Information systems in organisations

Information organizations in organisationsAbstractSuccessful outline roll-out is non a task that can easily be achieved. As many organisations and governments pick up found to their cost, it is non solely the case that they can throw m sensationy at an information brass in the hope that it testament be triumphful. The primary case study used is that of the capital of the social united Kingdom Ambulance Service Computer Aided transport placement. later aspect at the background of the case the instruction execution and subsequent disappointment ar discussed. The reasons for chastening are explained, which show the confound as essentially being doomed from the start. Although carcass blow is a common occurrence many organisations do not seem to learn from the mistakes of the past, resulting in several otherwise high profile cases. There are some(a)(prenominal) strategies, however, that can be adopted in coiffe to combat against failure, which mainly side on the s ofter aspects of system design such(prenominal) as management, organisational culture and man relations.What are the major causes of systems roll-out success or failure? What strategies can organisations take to ensure the success?To consequence this question fully we must first understand what an information system (IS) is and more primary(prenominal)ly, what constitutes the success and, or failure of an IS. An information system in an organization provides processes and information useful to its members and clients (Avison Fitzgerald, 2003). Flynn (1992) besides describes it as An information system provides procedures to record and make avail fit information, concerning single-valued function of an organization, to assist organizations-related activities.An IS is make up of a composite set of factors, including military man, organisational, technological, political and financial factors (Flowers, 1996). The interaction between these can give rise to either the success or failure of a system roll-out. The success of an IS is measured mainly on whether or not it pile ups the productivity target of being developed on meter and to budget, and the quality target of meeting the clients requirements. A made system is one that meets its targets of quality and productivity (Flynn, 1992). An IS is deemed thwarted if it fails either one, or both of its targets. In some instances the system is never actually delivered to the end user, which obviously is another case of system failure. An unsuccessful system is one that fails to meet either its quality or its productivity targets (Flynn, 1992).Successful system roll-out is not the easiest of tasks, with many governments and companies finding this out to their cost. In some cases these cost have run into hundreds of millions of pounds. The latest Standish sort report CHAOS Summary 2009 shows that more projects than ever are failing, and also that the number of successful projects is on the decrease. Only 32% of projects met their targets and could be classed as successful with 44% of systems meeting either only some or none of their targets and 24% were never completed (The Standish Group, 2009). There are estimates that the cost of project failure in the U.S. alone is well in excess of $100 billion emphasising just how costly a problem system roll-out can be if not done correctly.One reason as to wherefore in that respect are so many instances of IS failure is partly due to the fact that a deal out of the time they are constructed without a full understanding or anticipation of reality (Xalles particular(a), 2005). This is k directn as the Vacuum Mentality syndrome (Xalles Limited, 2005). These realities include changes in technology, changes made by the user community, reorganisations, changes of needs, change of key players and project sponsors, issues with resources and changes of processes (Xalles Limited, 2005). This idea is backed up by Maddison Darnton (1996) who explai n that human issues are usually more important than technical ones in determining success or failure. Highlighting the fact that it is not necessarily technical issues with an IS that are the main problems during the development process, but instead ones regarding human incompetence.One of the most dramatic IS failures report in recent years is that of the London Ambulance Service Computer Aided Despatch (LASCAD) system. The LAS is the biggest ambulance service in the military man, relations with over 2,500 emergency calls a day. This inevitably put massive strains on the manual paper-based system that was being used, which already had several major problems with it. This led to the standards of performance travel below the ones agreed to as part of the national standards for ambulance response.It was, therefore, imperative that a immature, more effective computer aided despatch system was introduced in order to meet the performance levels. The new system worked by a Control co nfederate receiving an emergency call and entering the details given by the caller into the CAD system. Using call-box identifier and chromosome mapping systems, the exact location of the caller was calculated. Based on the information on the incident the CAD consequently worked out a level for the emergency, thus informing the Control Assistant on the appropriate specializer vehicles and skills that should be deployed to the emergency. The most appropriate and closest vehicle to the incident was then pinpointed via the use of mobile data terminals and the vehicle tracking system, and despatched to the emergency. The CAD system sent details of the incident to the vehicle via the on-board computer. Throughout dealing with the incident the crew were constantly updating the CAD system as to their arrival at the scene, their vent from it, their arrival at the hospital, and finally when they were free to deal with another call (Flowers, 1996).The intention of the CAD system was to er adicate the inefficiencies of the old paper-based system. However, as the LAS soon found out this was far from the case. On Monday 26th October 1992 the spotless LASCAD system went live. It became quickly apparent, however, that it could note cope with the volume of calls. A number of calls were somehow getting lost in the system, leading to duplicate calls being made (Flowers, 1996). This meant that people who were in emergency situations had to wait, in some cases, for 30 minutes for their call to be dealt with. Even when the calls were dealt with, the ambulance allocation system had also failed meaning this had to be done manually, resulting in further delays. Amidst the confusion, it was even reported in some cases that two ambulances turned up to a single emergency, or that one never turned up at all (Flowers, 1996). As the day progressed, the number of calls increased, putting even more pressure on the already faltering system. The newer calls were now overwriting the earlie r calls, resulting in even more incidents not being dealt with. The situation became that bad that all the queues were exonerated in an attempt to decongest the system. However, this only succeeded in making the problem even worse, as a new flood of calls that were previously lost came through (Flowers, 1996).It was only Tuesday afternoon when the system was eventually shut deck as a result of the escalating situation (Finkelstein, 1993). The LAS were instead forced to revert to a former part computerised system. Just over a week later they were back using the fully manual system.It is out of the question to consider all of the factors that contributed to the dying of the CAD system. However, there are several major issues which could, ultimately, be seen as the contributing factors towards its failure. Flowers (1996) states that the primary reasons behind the failure were those of the design of the system, the management ethos, the procurement process and the timet sufficient t o which the system was developed. The system had been designed without sufficient testing, and on the basis that it would be operating in a perfect world where everything goes according to plan. It relied solely on the requirement that all the information received was perfect. In reality this was far from the case, and so the system was unable to sufficiently despatch resources to the incidents. As highlighted in the official inquiry into the failureIt is probable that the development team did not have full appreciation of the importance of these elements or, at least, of the consequences of failure, or less than perfect performance, of any one part (Finkelstein, 1993).The management ethos at the LAS was one that was inward looking and old-fashioned (Flowers, 1996). As a result of the recent restructuring which had been forced upon the LAS by the National Health Service, there were reported high levels of stress amongst senior management, which had seen a great number of previously loyal rung quitting (Mellor, 1994). In the years leading up to this there was a distinct lack of investment in areas such as the readying and development of managers. During the implementation process a report was commissioned by the LAS into staff attitudes. It was clear to see from the results that staff had little faith in the management and were not live up to with their jobs. This view had already been exposed from the result from a survey conducted in 1989 (Flowers, 1996).The official inquiry also highlighted a culture within the organisation that bred a fear of failure amongst the employees whereby the success of the system was the one and only consideration (Flowers, 1996). This created an atmosphere in which people were scared to mention any problems or doubts they had with the system. As a result the system had become a sacred cow, in the fact that it became unreasonably resistant to criticism from anyone associated with it.Senior managers believed that the system could be developed at a cost of just 1.5 million. To meet the stringent financial restrictions regarding the purchase of the system, it was recommended by the selection team that the LAS digest the lowest offer, no proceeds who the tender was unless they believed they had good and sufficient reason on the contrary (Flowers, 1996). The consequence of being forced to accept a tender in this manner was that the one with the lowest offer was an inexperienced small packet company that had gravely underestimated that task at hand hence the reason for their offer being well lower than all others. Having never worked on a project of this kind the companys resources were massively stretched, leading to falling standards in areas such as quality assurance, resulting in several mistakes being made with the development of the software.The stiff time subdue of just 6 months to which the system was set was far less than the industry just of 18 months for a project of this scale. It was believed by a vast majority within the LAS that the time scale was highly unrealistic. Inquiry Team member Paul Williams stated that The timetable was impossible (Mellor, 1994).Staff complained of the inadequacy of the training received for the system. There were major doubts about the quality of the training received and that it was provided long before the system was actually implemented meaning it was not as effective as it could have been. The situation was made even worse by the fact that the control room staff were trained separately to the ambulance staff, which caused the order-so for miscommunication.Other reasons include the fact that it had been decided by management that there was to be a distribute off between the performance of the system and usability. The system was developed with little input from system users such as ambulance crews, with no LAS staff being assigned full time to the project (Mellor, 1994).These, therefore, were not type conditions in which to launch th e new CAD system. Flowers (1996), on the other hand, argues that there is never an ideal time to introduce a major new computer system. However, he does also go on to say that rarely has such a large scale information system ever been introduced under such difficult circumstances (Flowers, 1996). This was not the first time that the LAS had tried to implement a CAD system for ambulances. Beginning in the early 1980s the system was doomed after tests revealed it would not be able to deal with the sheer volume of calls and so was abandoned in 1990 at a cost of 7.5 million. For a system roll-out to be successful it must contain these four phases Implementation Planning, Implementation Delivery, Post-Implementation Support, Post-Implementation Analysis (Xalles Limited, 2005). These implementation methods are based on a number of principles and assumptions. The approach by management to the project should be disciplined. As the case of the LASCAD has shown strong and effective management is essential for the success of a system. Managers should be able to competently handle and issues or problems that develop during the implementation of the system. Accurate and concentrated documentation is needed in order to effectively communicate throughout each of the implementation phases. The end user(s) should be kept in mind throughout the development process so that the System Requirement Specification can be met. It is essential that organisations learn from the mistakes of others regarding the roll-out of an information system. However, this can pose quite difficult as many organisations, if they have difficulties, tend to keep these problems in-house, as not to bring any negative press to themselves. In demonstration it is clear to see that the roll-out of a successful IS is not an easy achievement, with organisations not always learning from the mistakes of others. After reading several case studies of high profile IS failures including LASCAD, TAURUS and Heathrow Te rminal 5, it shows that the price of failure are extremely high with these companies losing tens of millions of pounds between them, and in the case of the LASCAD people losing their lives. These cases also highlighted that the main contributing factors towards the demise of each project were in fact from poor management, rather than technical difficulties. It is argued that the main factors for success act of timing and budget, perceived usefulness and ease of use, fitting the organisations business strategy and objectives, the management culture and human relations, and lastly acceptance of the system by the user(s) (Maddison Darnton, 1996). In order for a system roll-out to be successful all of this must be taken into consideration.BibliographyAvison, D. Fitzgerald, G. (2003).

The History Of The Digital Watermarking Techniques

The History Of The digital Watermarking TechniquesAbstractdigital waterlineing proficiencys have been actual to protect the procure of media signals. This field aims to contri moreovere a universal revaluation and primer about the watermarking definition, thought and the primary(prenominal) contributions in this field. The study leave behind start with a cosmopolitan view of digital information, the Internet and the products of these two, namely, the multimedia and the e-commerce. The study pull up stakes confronts an lengthy and deep literature refresh of the field of digital watermarking and watermarking algorithmic rules.Introductiondigital watermarking techniques have been developed to protect the right of first publication of media signals. Different watermarking schemes have been suggested for multimedia content ( personas, video and audio signal). This study aims to provide an extensive literature review of the multimedia copyright tax shelter. It prese nts a universal review and soil about the watermarking definition, concept and the main contributions in this field.Digital Intellectual spaceInformation is becoming widely on tap(predicate) via global networks. These connected networks fall by the moodside cross-references between informationbases. The advent of multimedia is allowing different applications to mix sound, grasps, and video and to move with enlarged amounts of information (e.g., in e-business, distance education, and gay-machine interface). The industry is investing to supply audio, image and video information in electronic form to customers, and open television system companies, major corporations and photo archives atomic number 18 converting their content from parallel of latitude to digital form. This movement from traditional content, much(prenominal) as paper catalogues, analog recordings, to digital media is due to several avails of digital media over the traditional media. close to of th ese advantages arThe quality of digital signals is prouder than that of their corresponding analogue signals. traditionalistic assets degrade in quality as time passes. Analogue information require expensive systems to obtain high quality copies, whereas digital data lav be easily copied without outlet of fidelity.Digital data (audio, image and video signals) dejection be easily genic over networks, for ensample the Internet. A large amount of multimedia data is now available to users all over the world. This expansion will continue at an even off heavy(p)er rate with the widening availability of advanced multimedia operate the like electronic commerce, advertising, interactive TV, digital libraries, and a spread more. take copies of digital data can be easily make. This is very recyclable but it also creates problems for the possessor of valuable digital data like precious digital images. Replicas of a presumption percentage of digital data can non be place and their origin cannot be confirmed. It is im accomplishable to determine which piece is the pilot light and which is the copy.It is possible to mist some information within digital data in such a way that data modifications argon undetectable for the human senses.Copyright Protection of Intellectual PropertyAn strategic factor that slows down the growth of multimedia-networked services is that authors, publishers and providers of multimedia data are reluctant to allow the distribution of their documents in a networked environment. This is because the ease of reproducing digital data in their exact original form is likely to get along copyright violation, data misappropriation and abuse. These are the problems of theft and distribution of mental property. Therefore, creators and distributors of digital data are actively seeking reliable solutions to the problems associated with copyright protection of multimedia data.Moreover, the future development of networked multimedia syste ms, in finicky on open networks like the Internet, is conditi unmatchedd by the development of in force(p) manners to protect data owners against unofficial copying and redistribution of the material put on the network. This will guarantee that their rights are saved and their assets properly managed. Copyright protection of multimedia data has been accomplished by means of cryptography algorithms to provide control over data gravel and to make data undecipherable to non-authorized users. However, encoding systems do not completely solve the problem, because once encryption is removed there is no more control on the scattering of data. The concept of digital watermarking arose plot trying to solve problems related to the copyright of intellectual property in digital media. It is utilise as a means to identify the owner or distributor of digital data. Watermarking is the exhi chomp of encoding hidden copyright information since it is possible today to hold in information messages within digital audio, video, images and texts, by taking into account the limitations of the human audio and visual systems.Digital Watermarking What, Why, When and How?It seems that digital watermarking is a good way to protect intellectual property from dirty copying. It provides a means of introduceding a message in a piece of digital data without destroying its value. Digital watermarking embeds a known message in a piece of digital data as a means of identifying the rightful owner of the data. These techniques can be used on many types of digital data including hitherto imagery, movies, and music.What is Digital Watermarking?A digital watermark is a signal permanently embedded into digital data (audio, images, video, and text) that can be detected or extracted later by means of computing operations in set to make assertions about the data. The watermark is hidden in the multitude data in such a way that it is inseparable from the data and so that it is resistant t o many operations not degrading the armament document. so by means of watermarking, the work is still accessible but permanently marked.Digital watermarking techniques derive from steganography, which means covered writing (from the Greek actors line stegano or covered and graphos or to write). Steganography is the science of communicating information while secrecy the existence of the communication. The final stage of steganography is to fog an information message infixed harmless messages in such a way that it is not possible even to detect that there is a secret message present. both(prenominal) steganography and watermarking belong to a category of information hiding, but the purposeives and conditions for the two techniques are just the opposite. In watermarking, for example, the principal(prenominal) information is the external data (e.g., images, voices, etc.). The internal data (e.g., watermark) are additional data for protect the external data and to prove posses sion. In steganography, however, the external data (referred to as a vessel, container, or dummy data) are not very important. They are just a carrier of the important information. The internal data are the most important. On the other hand, watermarking is not like encryption. Watermarking does not restrict access to the data while encryption has the aim of making messages unintelligible to any unauthorized persons who readiness intercept them. Once encrypted data is decrypted, the media is no longer protected. A watermark is designed to permanently reside in the host data. If the ownership of a digital work is in question, the information can be extracted to completely characterize the owner.Digital watermarking is an enabling engineering science for e-commerce strategies conditional and user-specific access to services and resources. Digital watermarking offers several advantages. The details of a good digital watermarking algorithm can be made public knowledge. Digital waterma rking provides the owner of a piece of digital data the means to mark the data invisibly. The mark could be used to serialize a piece of data as it is sold or used as a method to mark a valuable image. For example, this marking allows an owner to safely short letter an image for viewing but legally provides an embedded copyright to repeal others from posting the same image. Watermarks and attacks on watermarks are two sides of the same coin. The goal of both is to preserve the value of the digital data. However, the goal of a watermark is to be robust enough to resist attack but not at the expense of altering the value of the data being protected. On the other hand, the goal of the attack is to remove the watermark without destroying the value of the protected data. The contents of the image can be marked without visible loss of value or dependence on specific formats. For example a bitmap (BMP) image can be compressed to a JPEG image. The top is an image that requires less stora ge space but cannot be distinguished from the original. Generally, a JPEG conglutination level of 70% can be use without humanly visible degradation. This property of digital images allows insertion of additional data in the image without altering the value of the image. The message is hidden in unused visual space in the image and stays below the human visible threshold for the image.When Did the Technique Originate?The idea of hiding data in another media is very old, as set forth in the case of steganography. Nevertheless, the term digital watermarking first appeared in 1993, when Tirkel et al. (1993) presented two techniques to hide data in images. These methods were based on modifications to the least significant bit (LSB) of the pixel values.How Can We Build an Effective Watermarking Algorithm?It is desired that watermarks win image-processing manipulations such as rotation, scaling, image compression and image enhancement, for example. Taking advantage of the discrete wav elet transmute properties and robust features extraction techniques are the innovative trends that are used in the recent digital image watermarking methods. boldness against geometrical convertation is essential since image-publishing applications often apply some benignant of geometrical renderations to the image, and thus, an intellectual property ownership protection system should not be affected by these changes.Visible vs. Invisible WatermarksDigital watermarking is dissever into two main categories visible and concealed. The idea behind the visible watermark is very simple. It is equivalent to stamping a watermark on paper, and for this reason its sometimes said to be digitally stamped. An example of visible watermarking is provided by television channels, like BBC, whose logo is visibly superimposed on the corner of the TV run into. Invisible watermarking, on the other hand, is a far more labyrinthian concept. It is most often used to identify copyright data, lik e author, distributor, and so forth.Though a lot of question has been done in the line of business of invisible watermarks, much less has been done for visible watermarks. Visible and invisible watermarks both serve to deter theft but they do so in very different ways. Visible watermarks are especially effective for conveying an immediate claim of ownership (Mintzer, Braudaway Yeung, 1997). Their main advantage, in commandment at least, is the virtual elimination of the commercial value of a document to a would-be thief, without lessening the documents utility for legitimate, authorized purposes. Invisible watermarks, on the other hand, are more of an aid in catching a thief than for discouraging theft in the first place (Mintzer et al., 1997 Swanson et al., 1998).Watermarking sortThere are different classifications of invisible watermarking algorithms. The reason behind this is the massive diversity of watermarking schemes. Watermarking approaches can be distinguished in ter ms of watermarking host signal (still images, video signal, audio signal, integrated circuit design), and the availability of original signal during extraction (non-blind, semi-blind, blind). Also, they can be categorized based on the landing field used for watermarking embedding process, as shown in Figure 1. The watermarking application is considered one of the criteria for watermarking classification. Figure 2 shows the subcategories based on watermarking applications.Figure 1 salmagundi of watermarking algorithms based on existence used for the watermarking embedding processFigure 2 Classification of watermarking engineering science based on applicationsDigital Watermarking AlgorithmsCurrent watermarking techniques described in the literature can be assort into three main classes. The first includes the convert stadium methods, which embed the data by modulating the transform region signal coefficients. The second class includes the spatial theatre of operations techni ques. These embed the watermark by directly modifying the pixel values of the original image. The transform domain techniques have been found to have the greater rigor, when the watermarked signals are well-tried after having been subjected to common signal distortions. The third class is the feature domain technique. This technique takes into account region, boundary and object characteristics. Such watermarking methods may present additional advantages in terms of staining and recovery from geometric attacks, compared to antecedent approaches.The algorithms in this study are organized according to their embedding domain, as indicated in Figure 1. These are grouped intospatial domain techniquesTransform domain techniquesFeature domain techniquesHowever, due to the amount of published work in the field of watermarking technology, the main focus will be on wavelet-based watermarking technique papers. The wavelet domain is the most efficient domain for watermarking embedding so fa r. However, the review considers some other techniques, which serve the purpose of giving a broader picture of the existing watermarking algorithms. rough examples of spatial domain and fractal-based techniques will be reviewed.Spatial landed estate TechniquesThis section gives a brief introduction to the spatial domain technique to gives some background information about watermarking in this domain. many a(prenominal) spatial techniques are based on adding fixed amplitude actor noise (PN) sequences to an image. PN sequences are used as the spreading key when considering the host media as the noise in a spread spectrum system, where the watermark is the transmitted message. In this case, the PN sequence is used to spread the data bits over the spectrum to hide the data.Transform Domain TechniquesMany transform-based watermarking techniques have been proposed. To embed a watermark, a transformation is first applied to the host data, and then modifications are made to the transfor m coefficients. In this section, the state of the art of the current watermarking algorithms using the transform domain is presented. The section has three main parts, including sermons of waveletbased watermarking, DCT-based watermarking and fractal domain watermarking.Digital Watermarking utilize Wavelet DecompositionThis algorithm can easily be make into video watermarking applications based on a 3-D wavelet transform due to its simple structure. The hierarchical nature of the wavelet representation allows multi-resolutional detection of the digital watermark, which is a Gaussian distributed random vector added to all the high pass bands in the wavelet domain.Discrete Cosine Transform-Based Digital Watermarking some(prenominal) watermarking algorithms have been proposed to utilize the DCT. However, the follow et al. (1995, 1997) and the Koch and Zhao (1995) algorithms are the most well-known DCT-based algorithms. Cox et al. (1995) proposed the most well-known spread spectrum w atermarking schemes. Figure 3 shows the block plot of the Cox algorithm. The image is first subjected to a global DCT. Then, the 1,000 largest coefficients in the DCT domain are selected for watermarking. They used a Gaussian sequence of pseudo-random real total of length 1,000 as a watermark. This approach achieves good robustness against compression and other common signal processing attacks. This is a result of the selection of perceptually significant transform domain coefficients. However, the algorithm is in a weak position against the invariability attack proposed by Craver (1997). Also, the global DCT utilise on the image is computationally expensive.Fractal Transform-Based Digital WatermarkingThough a lot of work has been done in the area of invisible watermarks using the DCT and the wavelet-based methods, relatively few references exist for invisible watermarks based on the fractal transform. The reason for this might be the computational expense of the fractal transfo rm. In fractal analysis, similar patterns are place in an image and only a limited amount of double star code can be embedded using this method. Since fractal analysis is computationally expensive and some images do not have many large self-similar patterns, the techniques may not be suitable for oecumenic use.Feature Domain Techniques (Second Generation Watermarking)First generation watermarking (1GW) methods have been mainly focused on applying the watermarking on the entire image/video domain. However, this approach is not compatible with novel approaches for still image and video compression. JPEG2000 and MPEG4/7 precedents are the rude(a) techniques for image and video compression. They are region or object-based, as can be seen in the compression process. Also, the 1GW algorithms proposed so far do not satisfy the watermarking requirements.Second generation watermarking (2GW) was developed in order to add the robustness and invisibility and to overcome the weaknesses of 1 GW. The 2GW methods take into account region, boundary and object characteristics and give additional advantages in terms of detection and recovery from geometric attacks compared to first generation methods. Exploiting salient region or object features and characteristics of the image achieve this. Also, 2GW methods may be designed so that selective robustness to different classes of attacks is obtained. As a result, watermark flexibility will be improved considerably.Digital Watermarking and Image Processing AttacksDigital watermarking was claimed to be the supreme solution for copyright protection over the Internet when the concept of digital watermarking was first presented. However, some problems related to robustness and shelter of watermarking algorithms to intentional or unintentional attacks still remain unsolved. These problems must be solved in advance digital watermarking can be claimed to be the ultimate solution for copyright ownership protection in digital media. O ne of these problems is the effect of geometrical transformations such as rotation, translation and scaling on the recovery of the watermark. another(prenominal) is the aegis of the watermarking algorithm when intentional attackers make use of knowledge of the watermarking algorithm to destroy or remove the watermark.Watermarking Standardization IssueThe most important question about watermarking technology is whether watermarking will be standardized and used in the near future. There are several movements to standardize watermarking technology, but no one standard has prevailed at this moment in time. Some researchers have been working to develop a standardized manakin for protecting digital images and other multimedia content through technology create into media files and corresponding application software. However, they have lacked a clear vision of what the framework should be or how it would be used.In addition, there was a discussion about how and whether watermarking shou ld form part of the standard during the standardization process of JPEG2000. The requirements regarding security have been identified in the framework of JPEG2000. However, there has been neither in-depth clearing nor a harmonized effort to address watermarking issues. It is important to deduce what rattling needs to be standardized for including the watermarking concept in JPEG2000 and to what extent. The initial drafts of the JPEG2000 standard did not mention the issue of watermarking. However, there is a plan to escort how watermarking might be best applied within JPEG2000. The features of a given watermarking scheme are likely to offer designers an opportunity to integrate watermarking technology into JPEG2000 for different application such as distributing images on the Internet. Also, standardization of digital watermarking will influence the progress in imaging standards of JPEG2000 where the data security will be part of this standard. Therefore, the likelihood is that wat ermarking technology will be used in conjunction with JPEG2000 (Clark, 2000).Future HighlightsNevertheless, the future seems bright for digital watermarking. Many companies have already been active in digital watermarking research. For example, Microsoft has developed a prototype system that limits unauthorized playback of music by embedding a watermark that remains permanently attached to audio files. Such technology could be included as a default playback mechanism in future versions of the Windows operating system. If the music industry begins to include watermarks in its striving files, Windows would refuse to play copyrighted music released after a real date that was obtained illegally. Also, Microsoft Research has also invented a separate watermarking system that relies on graph theory to hide watermarks in software. Normally the security technology is hack able. However, if the technology is combined with proper legal enforcement, industry standards and prize of the privac y of individuals seeking to legitimately use intellectual property, digital watermarking will encourage content creators to trust the Internet more. There is a nasty amount of money at stake for many firms. The value of illegal copies of multimedia content distributed over the Internet could reach billions of dollars a year. It will be interesting to see how the development and adoption of digital watermarking plays out. With such high stakes involved for entertainment and other multimedia companies, they are likely to keep pushing for (and be willing to pay for) a secure technology that they can use to track and reduce copyright violation and capture some of their foregone revenues. Finally, it is expected that a great deal of effort must still be put into research before digital image watermarking can be widely authorized as legal evidence of ownership.ConclusionThis study was started with a general view of digital data, the Internet and the products of these two, namely, multim edia and e-commerce. It provided some initial background and history of digital watermarking. This study gave an extensive and deep literature review of the field of digital watermarking. The concept of digital watermarking and the requirements of digital watermarking were discussed and digital watermarking algorithms were reviewed. They were grouped into three main collections based on the embedding domain, that is, spatial domain techniques, transform domain techniques or feature domain techniques. The algorithm of the frequency domain were further subdivided into wavelet, DCT and fractal transform techniques. Finally, the future perspective of digital watermarking was highlighted.

Human evolution Theory And Social go bad Issues Social Work EssayThis study conveys with the utility of kind-hearted exploitation possibleness in intellect virtual(a) loving exploit issues. It takes up the case of the Murray family (provided in the appendix to this essay) and using the family as a base, attempts to obligate different aspects of worlde organic evolution surmise in a practical real smell scenario.The study is divided into five specific sections. The world-class section briefly describes the circumstances of the Murray family. This is followed by the application of cardinal theories of tender-hearted study, (a) Erik Eriksons psychosocial flummoxment theory and Bronfenbrenners Ecological Model of Human maturement, to understand minor and adult increment, (b) the ways in which policy-making and social processes catch human ontogenesis, (c) the role of inequalities in human victimization, and (d) the ways in which theories of human outgrowth und erpin social work knowledge and values.The Murray family scenario is elaborated in occurrence in the appendix to this study and is thus being taken up briefly here. sea dog (43) and Evelyn (36) Murray stay with their daughter Lora (6) and Evelyns mother Doris (71). Jack has dickens other sons, Seb (17) and David (15), who consist separately. Jack Murray was an adopted child. He was brought up by p atomic number 18nts who were open most his adopted status and has never sh take in each inclination to trace his biological p bents.Jack has alcohol related problems and is abandoned towards domestic violence. Evelyn has been hurt and that too badly, in the recent past. Lora is doing well in indoctrinate and is cared for by Doris, who is however becoming frail. She had to be showd in an emergency foster care surround during her summer holidays, even as her mother made use of a womens shelter to escape the difficulties of her home. Doris worries about being separated from her grand daughter and family if she were to go to a care home. All family members bugger off expressed their willingness to work with a social worker.Application of Theories of Human DevelopmentErik Eriksons theory of human development was first advanced in 1950 and has been signifi toleratetly augmented in later long time (Brenman-Gibson, 1997, p 329). Eriksons psychosocial theory states that brio terminate be segregated into 8 presents from birth to death, which comprise of (a) infancy (birth to 18 months), (b) early childhood (18 months to 3 years), (c) play age (3 to 5 years), (d) school age (5 to 12 years), (e) adolescence (12 to 18 years), (f) young maturity date (18 to 35 years), (g) middle adulthood (35 to 55 or 65 years) and (h) late adulthood (55 or 65 to death) (Brenman-Gibson, 1997, p 329).Each of Eriksons 8 stages involves a crisis that is characterised by two opposing emotional forces. Infancy, for instance, involves trust v mistrust and is characterised by the care of t he mother for a child with an emphasis on speck and visual take (Christiansen Palkovitz, 1998, p 133). Successful transition by this compass point firmness of purposes in someones learning to trust in life and to have authority in the future, even as problems during this period nooky lead to feelings of awkwardness and mistrust (Christiansen Palkovitz, 1998, p 133).The school age of 6 to 12 years is similarly characterised by the opposing forces of industry and inferiority (Brenman-Gibson, 1997, p 331). Individuals are capable of learning, building and achieving numerous skills and knowledge during this period, thereby developing feelings of industry. This stage of development dejection also lead to the experiencing of feelings of inferiority and inadequacy with peers and resolution in problems of egotism esteem and competence (Brenman-Gibson, 1997, p 331).Eriksons philosophy rests on two all-important(a) themes, namely (a) that the world enlarges as state go along, a nd (b) that failure is cumulative (Douvan, 1997, p 16). The first theme is indisputable. Whilst the second is debatable, it is align that children who have to perforce deal with difficult circumstances find it challenge to negotiate later stages in their becomes in comparison with others (Douvan, 1997, p 16). conglomerate studies have revealed that children who were not stroked as infants find it difficult to connect with others in their adulthood. Eriksons theory of human development has gained wide acceptance and is often utilise as a framework for intellectual the nature of issues that lead to occurrent doings and to prepare for the coming stages (Douvan, 1997, p 16).The analysis of the Murray family members reveal that Jack Murray could have suffered from lack of stroking in his infancy, especially up to his toleration at the age of 6 months. This could have resulted in entrenched feelings of clumsiness and tendencies to mistrust the world. much(prenominal) feelings, along with his experience of heightening up as an adopted child, may have inculcated feelings of low self esteem and be causal in his current drinking problems. Whilst Lora has grown up in the presence of affectionate parents and a loving grandmother, she is now entering the school age and the coming 6 years will enlarge her contact with the world, where parents whilst still important will not be the complete political science they have been until death.The application of Eriksons theory of human development helps social workers in understanding the various influences that individuals experience in the course of their lives and the roles of much(prenominal) influences in guiding their current demeanor and their emotional and social attitudes (Raeff Benson, 2003, p 61).Bronfenbrenners ecologic framework was first introduced in the early 1970s. His general ecological model is defined by 2 propositions (Brendtro, 2006, p 162). The first proposition states that human development, specifically in the early phases but also throughout life, occurs through processes that progressively become more complex and involve reciprocal interaction amidst active and evolving humans, who are bio-psychological in their approach, and the people, objects, and symbols in their immediate environment (Brendtro, 2006, p 162). Such interaction, when it occurs over extended time periods, on a regular basis are termed as proximal processes and can be found in activities between parent and children, children and children, and solitary or class play, as well as in reading, getting to know parvenue skills and per progress toing complex and difficult tasks (Brendtro, 2006, p 162).The second proposition states that the power, content, form and direction of these proximal processes influence development in a varying manner on account of the characteristics of developing individuals (Brendtro, 2006, p 162). Such development is also influenced by the environment in which such processes take localise and the nature of development outcomes that are under study. The mother infant interaction, (an important proximal process) emerges as an important predictor of developmental outcomes (Brendtro, 2006, p 162).Bronfenbrenners theory defines 4 different types of remainss, namely the Micro system, the Meso system, the Exo system and the big system, which inning human development (Austrian, 2002, p 43). The Micro system comprises of the family, classrooms and schools, and other systems in the proximal environment in which people operate. The Meso system represents the interaction of two little systems, the likes of the connection between the home and the school of a child (Austrian, 2002, p 43). The Exo system represents the environment that is external to the experience of an individual and in which his or her involvement is indirect, but which effects development, all the same. The employment of the parents of a child is a relevant example of an Exo system. The Macr o system represents the bigger cultural context (Austrian, 2002, p 43).Bronfenbrenners theory perceives the environment of a child in terms of quality and context and attempts to explain differences between the knowledge, development and skills of individuals through the structure, donjon and guidance of the societies in which they exist (Ahuja, 2006, p 3). He states that interaction between over lapping eco systems affect people significantly. Applying Bronfenbrenners theory to the Murray family, it can be seen that Loras family and classrooms can be called the little systems, which instantly influence her working and development (Ahuja, 2006, p 3). When these two micro systems get started working together to educate Lora, such education occurs through the Meso system. The lodge and culture in which Lora is being raised provides the underlying influence to these systems and is termed the Macro system. The comprehension of interaction of these systems helps in understanding t he way in which children develop and the factors that influence failure and success (Ahuja, 2006, p 3).Analysis of various micro and macro systems can help social workers significantly in understanding the various influences that shape the development of children. Researchers have in fact specifically found the significance of macro systems to be causal to general belief and feelings of low self esteem in individuals (Ahuja, 2006, p 3).The application of Bronfenbrenners theory in the Murray family scenario enables the development of greater understanding on the influences of different micro and Macro systems on the development of Lora in her school age and can help social workers to adopt appropriate intervention methods.Role of governmental and Social Processes on Human DevelopmentWhilst there is little interrogative sentence that the development of individuals is largely shaped by their home and school environments, sociological theory also places significant stress on the infl uence of larger society on such development (Grusec Hastings, 2008, p 42). All individuals grow up in specific political, cultural and social environments that shape their attitudes and behaviours and influence their development in specific ways. The particular societies in which people live are home to different types of religious, cultural and social attitudes, biases and beliefs (Grusec Hastings, 2008, p 42). Such political and social processes provide individuals with the means to participate within their own society, which itself contains shared customs, norms, traditions, values and social roles (Grusec Hastings, 2008, p 42). These processes are essentially life long, starting in childhood and continuing till death. Both Erikson and Bronfenbrenners theories deal with the process of assimilation but through different perspectivesSuch acculturation occurs through the influence of the family, religion, schools and peer groups, workplaces and the larger community (Berns, 2009 , p 131). These processes are also influenced by local media and political thought. Children and young adults are significantly influenced by their peers. Such influences can often be negative and result in substance abuse, premature sexual activity and the need to live up to wrong expectations (Berns, 2009, p 131). Mass media plays an immense role in influencing human development. The constant exposure of children to glamour, sexual satisfaction and violence can influence the development of children and young adults in various ways (Berns, 2009, p 131).With regard to the Murray family, it can well be understood that the personal development of all concerned individuals is likely to be influenced by different political and social processes. The continuance of domestic violence at home can lead to feelings of distress in Lora, especially when she compares her domestic environment to that of her friends, and wooing her to wish to shift to a more peaceful environment. Such socialisati on processes can furthermore leads to feelings of shame about her background and low self esteem, lead her to shun her family and take solace in her peers and spark of hooky player and delinquent behaviour.Impact of Inequalities on Human DevelopmentSocial work theory and knowledge primarily aims to diminish and eliminate the impact of inequalities on the lives of individuals (Neckerman, 2004, p 189). Inequalities can arise on account of various factors like income, education, gender and ethnic status. Such inequalities essentially serve to reduce supererogatory of affected people to various facilities and reduce the prospects of their life outcomes and their chances to lead ruler and enriching lives, inequalities in income can for example deprive the children of such families from various educational and other facilities and severely diminish their life outcomes (Neckerman, 2004, p 189). Such inequalities can also generate feelings of low esteem and result in suboptimal feat in and out of school during childhood and in the workplace in adult life. Numerous studies have revealed that children with poorly educated parents receive significantly lesser educational sustenance and support at home, which in bowl over affects their cognitive development and adversely influences their performance at school (Marger, 2004, p 86). Lora the 6 year old Murray child has until now done in truth well in school. The disturbed domestic situation in her house, especially the gender inequality between her parents and the domestic violence faced by her mother can well result in poorer educational support at home, especially when she is moving into the learning stage and needs it the most. grammatical gender inequality has been widely accepted to be an important factor in the anisometric life chances offered to men and women of societies across the world and has resulted in unequal development and life chances of the two sexes (Marger, 2004, p 86).Influence of Human Developmen t Theories on Social Work Knowledge and ValuesTheories of human development help in shaping the ideas of readers on the essence of human behaviour (Austrian, 2002, p 56). It expands the understanding of individuals of the scope, the potential and complexity of human function. Whilst scholars of human development do not agree on or endorse a single theory, many of these theories provide new perspectives for the observation and interpretation of human behaviour (Austrian, 2002, p 56). Piagets theory of cognitive development has resulted in a new appreciation for the ways in which children construct sense and meat out of their experiences (Raeff Benson, 2003, p 81). Eriksons psychosocial theory highlights the concept of identity, even as the social learning theory of Bandura has resulted in the widespread use of modelling to imitate conditions under which children increase their learning by observing and imitating the behaviour of others (Raeff Benson, 2003, p 81). The social work profession draws extensively on theories of human development for understanding the behaviour of individuals, with specific regard to the causal influences of such behaviour. An understanding of such theories not only enables social workers to understand the causes for human behaviour but also helps them to plan appropriate interventions to improve the social, emotional and sparing conditions of people (Raeff Benson, 2003, p 81). It helps social workers to understand the dynamic interaction that takes place among human beings and the impact of social systems upon the lives of people. A greater understanding of such theories also helps social workers in appreciating human diversity, as well as the impact of different actions in helping human beings to access opportunities and go that foster realisation of social and economic justice (Austrian, 2002, p 56).Conclusions

London Underground Extension Project Management

capital of the United Kingdom Underground Extension Project counselingThe Jubilee follow origin all(prenominal)y opened in 1979 and consisted of 2 and a fractional mile tunnel leading from Baker Street to Charing Cross. until now delinquent to the short distance of line compared to others there was a need for an fender to fill the void. At the time the London transportation system did not fully accommodate direct train access to areas such as Westminster, the business sector in docklands and most of South and East London. London underground Ltd decided to extend the 2 and half mile line with an additional 10 miles from Green Park to Stratford.London Underground Ltd had already visualisened to undertake a extension of the line along with mixed other project such as creating new lines. However as with most public sector projects regimen approval was necessary in the first place work could commence. Initially the project faced being scrapped during parliamentary debates. fortu nately it was saved by its main selling point which was unlike whatsoever of the other lines underground the jubilee line would be competent to interchange into all existing underground lines. (Kenneth powell). Moreover the proposal for the line accommodated, one of Europes instantaneous growing business districts (Canary Wharf), the lack of transport links in south London (London bridge inter change) the regeneration of East London (Stratford) and a addition transport link to Parliament (Westminster). (Kenneth powell) The government eventually sanctioned and bearingated funding for the project on 29th October 1993 with crook beginning in December (JLE project bob mic Page 48-49). The expected project culmination time to be narrow around spring 1998, lasting a total of 52months and the estimated was approximately 2.1bn in 1994 (BBC).At the tendering stage It was decided that more than 30 major nail downs and a emergence of smaller contracts will be awarded this posed a te st on how the project would be managed actor being the difficulties that could arise from multiple contracts. (JLE project bob mic ) The contrasting contracts were awarded for legion(predicate) amounts of activities such as tunnelling, signalling and communication, M and E, the edifice of the 11 new station and other various works. (Kenneth powell JBLE).The WNSL opted for a low peril method of procurement known as design and build which the Australian contractor win the tender phone for the price of 326.5m (guardian). With design and build the contractor (multiplex) is ordained to design and build the project, this generally gives the contractor overall control of the project. However the contractor must follow the customers (WNSL) instructions from the brief. The client will let a employers agent is hired to monitor the state of affairs and enforce their instructions. (Murdock and Huges)The customer choose a fixed price contract with the contractors after the bid was signed it was agreed between both parties that the price would increase to 445m. earlier at the proposal stage the scheduled time for completion was set to be late 2003, however this goal was perceived to be unworkable due to the nature of the time the bid was won. As a return a realistic date was agreed upon with a stipulation that a penalty payment would incur if the project was over due by 31 Jan 2006. ()The concept of this project came about from the realisation in the archeozoic 1960s there was a lack of facilities and shortage of space in the British m dropums attic interpret room in Bloomsbury. It was decided that something had to be done to preserve the national library and an act was passed to re-house the increasing accretion and build a national library. (the British library, colin st john Wilson) Different design concepts were proposed based on the intentions of retaining the library in Bloomsbury but smashing it a yet three floors. However they did not allow fo r much room for design changes one construction commenced. The government approved the design in 1964 to expand the reading room with in the library. However there were strong debates which suggested that the dome reading room expansion should be scrapped since it would not be able to keep up with the storage demand of books in the future. This lead to the government ratifying their original decision and in 1973 the British library act allow the library to be constructed as a sever entity from the museum. (Inside the British Library, by Alan day)Even though the project had been approved to be a separate mental synthesis, the location had still not been decided, there was protests do by the reading room staff for the library to be built in Bloomsbury. The rootage was to build in the St Pancras area because of the convenience of the large space and the identification number of transport links there. ( the british library, colin st john Wilson)In 1975 the decision was made to move the project from Bloomsbury to St Pancras. The final design offered a library with number of reading room for humanities, science, business and various other shadejects, a plaza, offices, laboratories and conferences rooms. The building was proposed to be built in three phases and would have been able to go along all incoming books without storage out houses. The first stage of construction was approved in 1980 with excavation and construction of the site began in 1984 and was meant to be complete in 1993 at a cost of 170m.The procurement scheme that was chosen for Phase 1A of the project was management contract this was very convertible to JCT construction four-in-hand. However at the time this was not a JCT model form of contract, since JCT had not issued this method and it was not commonly used in the UK. (Murdock.J ,Hughes. W) The Management contracts was design to be a method of procurement use for high jeopardize and complex projects, with the purpose of reducing the r isk which is commonly exposed to the contractor/ managing contractor. The idea behind this modified construction manager contract is the client employs a design team and hires a construction manager to help coordinate the design and construction and to supervise site activity. There is no main contractor and all the work is sub contracted out, construction is divided into individual work packages carried out by different trade contractors.The use of Management contract had a invalidating effect on the project because there was literally no risk directed to the managing contractor and therefore no one to blame in the occurrence of cost over-runs and time delays. (Murdock.J, Hughes. W) In Hindsight one of the main causes for hardship with project was as a result of the procurement method chosen. It was considered by Day that the four key weaknesses with the management contract wereThe aim of contract choice should always be to distribute risk clearly the client needs to understand that each procurement thoroughfare decides the level of risk that brook be controlled by the parties involved. With the help of contract consultants the client groundwork be advised on the best procurement option that suits their needs. No one procurement system is better than another, each procurement route is designated for different circumstances.The majority of these risks can be trace back to procurement route and the success or failure of a project can depend on the choice of procurement reason being that different contracts have different clauses, and each contract has its own contingency plan which distributes the risk according to the situation and who is responsible for the risk.

Its Improving Home Energy Efficiency Construction Essay

Its upward(a) Home Energy expertness Construction EssayIntroductionThe typic piazza right away has an unquenchable thirst for brawn and there argon numerous steps homeowners chamberpot acquire to help lower their distinguish for nil. The main source for todays nothing is fossil elicits. The burning of these fossil fuels give ups carbon dioxide and CO2 is a major contri thoor to global warming. It is important that we take a much sustainable approach towards our vim usage. Sustainable energy usage benefits the environment and results in lower energy costs to the consumer. grammatical construction ShellThe exterior surfaces of a building are called the building lawsuit this may include the roof, seawalls, doors, and windowpanes. It is the proceedsiveness or ineffectiveness rather, of this scold that determines the take of energy demand a building exit film. It is the lovingness reciprocation through with(predicate) the buildings shell that places the large st demands on energy consumption of the home.Lets take a minute to focus on the walls and social structure with respects towards the building shell. A common trend in architecture today is to have m both extrusions and intrusions in the walls of a home. This is more aesthetically pleasing to todays homeowner. However, these extrusions conduct unneeded framing which results in decreased insulant in corners and probable melodic line passing water. Most single family re perspectivential homes are wood framed and any irregularities in the building shell are weak points when it comes to heat loss. busy homes are framed with metal studs, generally speaking. The increased metal front man combined with thinner walls and joints betwixt modular slits all create potential weak spots that allow greater thermal askivity. Multi-family housing units pay off from some of the same design flaws much of their structural support comes from metal components, larger billet handling units, and elevator shafts create weak points, thermally speaking. However from an energy usage point it is better to have an flatbed that is surrounded by some other apartments, the temperature change from one side of your wall/ crownwork ordain be al most(prenominal) cryptograph, this equates to lower heating and serene down costs. Later I lead discuss breed leakage and withdrawal more in-depth, for now just knows that when it comes to the exterior design of a building, simpler is better. wrinkle LeakageWhat re renders 5-40% of building teach costs also known as energy consumption, air leakage does. pedigree leakage is the exchange of air from the exterior to interior, or vice versa, of a building. Air leakage keep in line dirty dog increase ease, sign on damage to intra-wall components, prevent pest infestation, and save energy. While ventilation is needed for the building and human health, the goal is to subordination that ventilation and have it happen when we deem i t necessary. Ultimately this exchange in air is a result of pressure difference from the inside to distant of a structure. The pressure difference is ca mathematical functiond by the density difference in warm and cold air. This c at a timept is also known as the mho law of thermodynamics that is that warm will always move to cooler areas (when unassisted) until balance is met. Unchecked airflow will seek equilibrium inside and extracurricular by the most direct path. Examples of this sue at work during spend months would be warm air exiting the structure through leaks in the upper regions of the building and cool air entering through the lower regions, so creating a cycle that seeks equilibrium. Residents can prevent/ decoct air leakage by ensuring that the building shell is halally loaded, air tight. This task can be accomplished by using spray fizz well-nigh window and door frames as well as checking that the weather-stripping is in ripe condition, non worn out. Also, windows and doors must be latched in order to be air tight, it is not uncommon for a window to closed but not latched. Other building practices that should be avoided include duct work, galvanic fixtures, and plumbing components being placed in exterior surfaces. This could cause air leakage as well as reduced insulation where these components are present.InsulationInsulation prevents heat transmission through the building shell. In some winter months heat transmission poses a greater panic than air leakage. Insulation is placed in voids/cavities in the building structure to reduce heat transmission. Insulation accomplishes this goal by two means. It forces heat to transfer in the socio-economic class of a swash, gasses are inbornly woeful conductors. Second its presence reduces heat convection and radiation. Insulation comes in many forms it could be foam, fiberglass, wool, cellulose (shredded newspapers), and even straw bales in some construction. Every type of insulation h as its own pros and cons. Foam is by far the most effective, it has very spunky R-values and if sprayed will expand to fill air leaks, on the down side it can be expensive, is not very fire resistant, and does not explicate down quickly in a land fill (eventually this is where it will end up). Fiber glass is probably the most prevalent form of insulation it has good R-values, but until the wall is sealed can release particles into the air that are harmful if consumed. Wool/cotton is probably a more sustainable way to insulate a structure, generally it is do out of recycled jeans, can achieve comparable R-values, but due to its unpopularity can be significantly more expensive than more common insulations. Cellulose ranks approximately the same as wool, it is recycled content, but is blown in place and often will settle over time this leaves a small section of the cavity insulated once it settles. Straw-bale insulation is a controversial issue, its density makes it a good insulat or, and however there is much debate about how farseeing it will last. Each insulation is designated a specific R-value and is labeled as such. The R-value is a measure of how well the material resists heat transmission. The important amour to know about R-values is the higher the better, slight heat transfer equals less energy consumption. The inverse of the R-value is the U-value. U-values are used to localise windows and doors for their qualification.Windows entrysWindows and doors are the pass off opposite of insulation. So much so, that we do not rate them by their ability to resist thermal conductivity, but by their ability to conduct thermal heat transfer. The way we identify windows and doors also known as fenestration is with a U-value. The National Fenestration Rating Council is the private/public group tasked with interrogation and assigning a U order to fenestrations. Windows are make up of four basic parts the glass, sash, frame, and the rough disruption, al l of these contribute to a windows in skill regarding energy. Windows can have several opposite types of glass including Low-e, tinted bronze, reflective bronze, and clear glass. The best option for energy savings is to install an insulated, Low-e window. The insulative property is supplyd by a gas, unremarkably co2 and argon. The gas is injected between the window panes and sealed in place the use of a gas reduces the rate of convection between panes. The low-e is a coating placed on one pane of glass, usually inside the window, that reflects radiation. This coating is installed on the interior pane for cooler climates and on the exterior pane for warmer climates. The sash/frame is typically made of similar material, being moldable, metal, or wood. With relation to energy consumption the plastic construction is the way to go. When made of plastic the sash/frame is extruded through a mold and often can be fill up with foam insulation. The rough opening refers to the space betwe en the window frame and the structural frame of the opening in the rough framing (the actual opening in the wall). The rough opening is often larger than the frame of the window to allow the builder to make adjustments during installation. Once installed, this space should be filled with insulation the best to use for this situation is minimal expanding foam spray. Door construction is very similar. Doors can have glazing/fenestration within the door. They too, are granted a U-value. When discussing the U-value of doors/windows the most important for a consumer to know is that the lower the U-value, the better. displace U-values result in greater energy savings when heating and engine cooling brass a building.HeatingIn North America the heating demands of our homes require a huge amount of energy. This energy comes from mostly from fossil fuels that have been refined, mined, and converted to meet our needs. The residential heating fuels that are used today can be broken down int o four major categories natural gas 53%, electricity 29%, oil 9%, and other types make up the remaining 9%. Huge natural gas reserves have been found in North America and it is considered to be the most environmentally complaisant of the fossil fuels. It is the increased availability and societies continue for the environment that has led to exponential growth most recently in the natural gas industry. Electricity is considered to be 100% efficacious once harvested. It is the methods by which we harvest electricity that cause environmental damage. The most environmentally degrading method of harvesting electricity is by coal office plants however more sustainable methods such as harnessing wind and solar motive production are being developed and implemented. Some galvanic providers allow their customers to select the source/means of their power. Oil, once a major source of energy used to heat our homes is becoming quickly noncurrent as consumers become aware of more efficient and environmentally friendly ways to heat their homes. The other category refers to heat sources such as wood and coal, aside from the environmental impacts these sources are unpopular because they require more work by the consumer. A heating governance should be intentional to provide the home with heat at approximately the same rate that it is being lost in worst case scenarios. Each fuel type has a distribution system. These systems are given an ability rating. This rating measures how well the system operates and can be expressed as Efficiency = Output Input. The resultant will be a percentage ranging from 35-95% efficient. The efficiency of a system is directly proportionate to the amount of fuel the system consumes. Therefore, the more efficient a system is, the less energy it will consume. High efficiency systems are considered to be any system with an 80-97% efficiency rating.CoolingSecond to heating demands are the cooling demands, generally speaking, of a building. The re are passive and active methods of cooling a structure. Depending on the designers knowledge and foresight of these methods energy required to cool the structure could set off greatly. Passive methods require no mechanical operations the result is zero energy consumption. Active methods require the assistance of mechanical operations, although the level of energy consumption is defendant upon the system that is installed. Often it is a combination of these methods that provides the most comfort to the inhabitants of the home. One common passive method of cooling a structure is through the use of landscaping. The use of trees to shade a home is the most cost effective method of cooling. The trees must be broad-leafed so that they allow the sun to warm the building during winter months. some other passive method is ventilation through windows and other openings. A proper building design can create a chimney restore, puff cooler air in at lower portions of the home and psychot herapeutic warm air in upper portions of the home. Often this chimney affect can be assisted by proper placement of ceiling fans, an example of a combination of passive and active systems. The use of fans to refresh a home is the most energy efficient way to cool the building. Moving air is more comfortable to the inhabitants and can give the detection of a 4-8 degree temperature change. Window/Room air conditioners are the least(prenominal) energy efficient. The constant originate up and shut down process consumes large amounts of energy. They are subject to significant accumulations of dirt, unchecked over time, this causes greater inefficiency and eventual failure of the unit. The use of central air conditioning is another(prenominal) active method to cool a residence. Central air conditioning can provide the most comfort higher efficiency models reduce energy consumption. Central air conditioning systems are run by a thermostat and slowly cool a building. This prevents the c onstant start up and shut down process that occurs with a window unit. disregardless of the system and methods used to cool a building the inhabitants have chair over how much energy is used. The warmer the environment the residents can willingly tolerate the less energy will be consumed to cool the structure. referable to the fact that most people do are not present during the construction and design process of their home perhaps the most relevant way to save energy is to perform regular maintenance and select the proper lighting and appliances.LightingLighting has a huge effect on a homes energy consumption. There are many polar light fixtures and bulbs a one could install in a home. vertical as anything else thus far they vary in efficiency. The consumer must rake labels to ensure they are actually purchasing the most sustainable, energy efficient light. Often more lighting than what is required is used, different activities require different levels of illumination, be sur e to size fixtures adequately. Consumers must monitor their energy use by controlling when lights are on or off. If an area is not being utilized for a period of time the lights should be off off to conserve energy. Also, residents should refreshful the globes or covers around the light bulbs, clean fixtures provide more optimal lighting. When purchasing new appliances consumers should purchase energy star rated appliances. Energy Star guidelines are set by the EPA and provide the consumer with a means of determining the efficiency of appliances such as deal washers, TVs, clothes washers, and dryers. To help with the cost of these more efficient options some accede governments offer a tax rebate to those who purchase high efficiency appliances.ConclusionIn conclusion, even with the unquenchable thirst for energy, the consumer has more power than they realize to reduce the energy consumption of the buildings they reside in. With reference to the buildings shell basic is better irr egularities tend to be thermal weak spots. Air leakage can happen anywhere the building shell is penetrated, fish filet the unregulated air flow through a buildings shell will result in increased energy savings. The proper insulation is key, to providing comfort and energy efficiency. Windows and doors also known as fenestration create weak points in a buildings shell and must be sealed and properly installed to erect energy efficiency. Heating systems are produced by a wide miscellany of manufactures, it is crucial that the consumer is well informed with the potential energy consumption of the system before purchasing and installing. Cooling can be accomplished through passive and active means, often the most effective is a combination of both. Lighting fixtures must be sized and installed properly to promote energy efficiency. Consumers should purchase high efficiency Energy Star appliances to conserve and reduce their homes energy consumption.

Statistical Analysis: Causes and Death and Illness

Statistical Analysis Causes and Death and IllnessMeagan AtchesonThe statistics around piddles of stopping point argon dictatorial as come up as vital in determining and monitoring the wellness post of populations as well as for identifying unfavourable priorities for various health systems. Most industrialized countries feed good systems in place to determine the main causes of last. In origin to this, ontogeny countries ar non as advanced in placing much(prenominal) systems which proves bad in trying to improve the everyplaceall health of the nation. Indeed, there atomic number 18 vast protestences in the top causes of final st eon deep d suffer developed countries versus the underdeveloped countries. This canvas entrust comp ar and contrast the top louvre causes of decease in the United situates of America and in atomic number 16 Africa as well as provide evidence and ex platformations for these differences. Moreover, it ordain critically discuss th e take a chance factors, health polity, malady progression and manipulation advances or wishing whencece with regard to particular causes in each context. Finally, it will address legitimate approaches contracted to improve the health of populations.The most funda psychical aspect of each health policy looks at methods to maintain as well as improve the health status of a population. Defining the health of a nation as well as how health is measured is critical to any health c ar system (Kr iodinenfeld, 2002). The creative activity health transcription defines health not only in terms of the negative exposition where health is seen as the absence of malady but similarly incorporates physical, mental and social well being (World wellness Organization, 1948). Mortality rates ar the basic form of measurement needed to asses health status. By calculation the number of deaths in a year and comparing it to preceding long time, the health status of various populations lot be determined (Ogden, 2007).Health statistics take aim shown that sicknesss, their occurrence as well as mortality rates differ from one boorish to the next more specifically developed countries as opposed to exploitation countries (Tool Tool, 2004). Developed or industrialised countries such as the USA are typically more economically advanced with a high school level of economic growth and standard of living as well as advanced technological infrastructure. In contrast to this, developing countries like southwest Africa get to a lower standard of living, are under industrialised and have poorer economic growth (Szirmai, 2005).Ranking causes of death is an extremely useful method for re empowering mortality statistics (Ogden, 2007).The U.S plane section of health and homophile services released a report at the end of 2009 on the tether causes of death in the United States by age, sex and race. The top five causes death in rank order were found to be disorders of the sto ck ticker malignant neoplasms chronic lower respiratory diseases cerebrovascular disease and accidents (unwitting injury). It is imperative to note the differences in ranks for age. For precedent the track causes of death for infants were accidents congenital malformations deformations chromosomal abnormalities and malignant neoplasms. This differed to the age group of surrounded by 2-44 years where the leading causes were unintentional injuries, homicide as well as suicide. For one-on-ones over 45, the primary causes of mortality separately were breast disease and stoogecer. Certain variations and similarities exist in the midst of the unlike genders. For both(prenominal) genders, midpoint disease and cancer were the initiatory and cooperate leading causes of death. The troika cause for men was unintentional injury versus stroke for women. The fourth leading cause for both sexes was chronic lower respiratory disease followed by stroke for men and Alzheimers for women. Little deviation was found among the different races (Heron, 2012). These leave alones remained the same for info collected in 2011 (Hoyert Xu, 2012).The atomic number 16 African statistical release for 2010 showed terabyte (TB) to be the leading natural cause of death. The second leading cause of death was flu and pneumonia. The third primary cause was enteral infectious diseases followed by other forms of mall disease (not Ischaemic) and hence cerebrovascular diseases. The first twain causes tuberculosis and influenza and pneumonia were the top two causes for both male and female. The third leading cause for women was cerebrovascular disease followed by enteric infectious disease and thus other forms of inwardness disease. This differed to that of the male group whose third leading cause of death was intestinal infectious disease followed by other forms of marrow disease and therefore cerebrovascular disease. The age group as well as the various provinces in South Af rica were included in this statistical report to lucubrate s washy differences in the top causes of death. In the cease State as well as in Limpopo, the leading cause of death was influenza and pneumonia unlike all other distinguishs where tuberculosis remained the main cause of death. The study death cause for children below the age of fifteen years was intestinal infectious disease compared to the age group 15-64 whose main reason for death was collectible(p) to TB. For those aged over 65, cerebrovascular disease caused the most deaths (Statistics South Africa, 2010).Being a developing country, South African soulfulnesss face a high chance of contracting and dying from Tuberculosis. Tuberculosis is a disease where bacteria enters and invades various body threads such as the lungs, brain and kidney. It is administer from individuals who contain the untreated, active form of the Tuberculosis bacteria through droplets releases into the activate via coughing, sneezing or sp eaking (Wouk, 2010). Although there are numerous run a jeopardy factors for TB, it mostly affects poorer individuals who are living in rural areas with a lack of affordability for transport as well as treatment, people with weak tolerant systems, those who lack access to Directly Observed Treatment, Short course (DOTS) as well as those who are uninsured. Furthermore, the strongest gamble factor for the development of TB is human immunodeficiency virus. These two diseases continue to have a deadly association as each drives the development of the other. Drug resistant strains of the TB bacteria is a huge risk factor leading to the enormous amounts of deaths in South Africa (Davies, 2005). Moreover, the poor health care system as well as the trammel number of properly trained health arrive aters in South Africa threatens the majority of people who contract Tuberculosis (Downing, Gwyther, Mwangi-Powell, 2012).The national surgical incision of Health in South Africa implemented the National Tuberculosis hear program which aimed to reduce mortality due to TB as well as keep backion of medicate resistance development by 2005. However, the health policy surrounding TB in South Africa needs to be built considerably in various areas. Firstly, public health services need to improve DOTS implementation as well as more accent mark needs to be placed on access and utilisation of health services (World Health Organization, 2009). Moreover, different approaches need to be taken in regard to the HIV on TB relationship. Furthermore, higher quality strategies are needed for better TB diagnosis and treatment (South African Department of health, 2004)Although TB is curable, it is the progression from latent TB infection to multidrug- resistant TB that results in the high mortality figures in South Africa. Individuals with latent TB infection show no signs and symptoms of the disease as it is still in the harmless stage. However, if these individuals do not receive proper treatment, reflecting majority of the graphic symbols nonplus in South Africa, it develops into TB disease. It usually starts out with damage to lung tissue but frequently lands up affecting many body tissues and organs. Moreover, TB is extremely resilient and adaptable. Often in developing countries, the right junto of drugs are not taken for the right amount of time due to a large number of reasons such as poverty and this then leads to multidrug-resistant TB. If left untreated multi-drug resistant TB can be mordant (Dyer, 2010).There have been major efforts to improve TB go for and treatment in South Africa. Fixed dose combination tablets (FDCS) were introduced in 2000 in the hope of pr regulartion of resistance and easier administration. Together with the combination tablets, pointly notice treatment is enforced to ensure treatment adherence and to do prevent emergence of drug resistance (South African Department of health, 2004). Despite these efforts, the TB in cidence and fatality rates still continue to increase. It is therefore not a lack of treatment that hinders South Africa from reaching their target for TB overtop, but rather a lack of appropriate infection control measures in public health settings together with the high prevalence of HIV that results in increased numbers of drug resistant TB themes (Weyer, 2007). midriff disease in developed countries like the United States is mostly attributed to individual deportment and lifestyle unlike TB in South Africa. This disease can be linked to risk factors such as smoking, foaming diet, alcohol abuse, diabetes, lack of physical activity as well as high blood cholesterol and blood pressure. Age, heredity and gender too play a role in the development of heart disease (Brannon Feist, 2010). In contrast to developing countries, Americans face very different risk factors which can often be attributed to their fast paced and busy lifestyles.America implemented a public health achieve ment plan to prevent heart disease and stroke which addresses an urgent need for the action of prevention. This is in contrast to South Africas health policy that still needs to be strengthened. Public health agencies together with the general public of America are needed to help promote the national goals of preventing heart disease as support for these health programmes continue to remain low. The American health action plan aims to improve cardiovascular health through prevention, archaeozoic detective work as well as treatment of various risk factors. This plan similarly includes developing modern health policies that includes innovative intervention programmes for in particular high risk groups that will result in measurable impacts (U.S. department of health and human services, n.d.)Heart disease is a chronic former that tends to get worse over time. Unlike TB, heart disease is not infectious and cannot be spread from one person to the next which is often the case in smal l areas such as the townships in developing countries. Heart disease is mostly a direct result of lifestyle choices. Furthermore, the progression of heart disease can go bad extremely unpredictable as it is different for each person. In some instances, the symptoms of the disease can remain stable over months or even years sooner becoming worse, while in others these symptoms may rapidly development. In America, early stages of heart disease are seen as early as age 15. Hypertension as well as other cardiovascular risk factors has all been linked to the progression of heart failure (Abraham, 2001).New treatments for heart disease have dramatically improved the life expectancy of these individuals in America. Drugs such as statins, antihypertensive agents, thrombolytic agents, anti-platelet as well as anti-coagulation therapies have all proved to be effective treatments. Moreover, novel guile based therapies is an advancement in treatment that has contributed to a decline in card iac mortality in the United States. Through being a developed country, they have access to modern genetics and genomics that will impart for more targeted use of drugs to emerge in the future which will greatly improve the effectiveness of therapy. This is in contrast to South Africas limited resources and modern medical advances that still allow drug resistant TB to be a major cause of death (Weisfeldt Zieman, 2007).Apart from cerebrovascular disease and some forms of heart disease, the leading causes of mortality differed significantly mingled with the United States and South Africa. These variations can be explained by the different risk factors, health policies, disease progressions as well as treatment advances or a lack thereof between the two countries. In contrast to developed countries, developing countries have vastly different health priorities due to a diverse set of risks. The many factors such under industrialization, high unemployment rates, underdeveloped health c are system as well as the low standards of living is the answer to why causes of death are so unalike. Moreover, the problems in the quality of health care need to be intercommunicate in order to see the health of South Africans improve. In America, special intervention programmes need to be introduced to help better the health status of the nation. Furthermore, through the comparisons of the approaches South Africa takes in regard to Tuberculosis versus the approach to heart disease taken in America, proper explanations of the mortality cause differences can be seen.ReferencesAbraham, W.

Tuberculosis.NY Marshall Cavendish Corporation.Is internationalisation Undermining State Sovereignty?Is Globalisation Undermining State Sovereignty?Is globalisation undermining postulate sovereignty?Throughout the years it has been argued that globalization has a significant effect on enjoin sovereignty. That current debate between scholars and social scientists is trying to determine whether or not invoke can still maintain its own sovereignty. Weiss (1998) suggests that there are certain factors such as investments in supranational parsimoniousness, multinational corporations and non- organizational organizations which demoralize the recite sovereignty. On the other hand, Krasner (2001) argues that in the past similar things such as free swap exist ed and postulate sovereignty was able to dominate. The essay will focus on defining globalization and sovereignty. Then it will observe how multinational corporations, inter-governmental organizations, wanton market scrimping and unlike crime can reduce dry lands power and therefore disobey sovereignty.Sovereignty is a very broad term which Barkin and Cronin (1994, p.107-30) simply defines as the power of submit to make and amend any law at bottom its own accede boundaries. Moreover, sovereignty is defined as the absolute advantage over subjective affairs within its dominion, absolute right to govern its people, and freedom from any external interference in the above matters (Martinez, 1996 Wang, 2004, p.473). The landed estate is the supreme political authority within its territory and therefore it does not recognize any higher political authority outside it. With this definition it would be easier to determine whether or not globalization affects certain aspects of it. Beekens (2003, p.130) illustrates globalization as the world-wide interconnectedness between nation states supplemented by globalization as a process in which basic social arrangements (such as power, culture, markets, politics, rights, values, norms, ideology, identity, citizenship, and solidarity) become disembedded from their spatial context (mainly, the nation-state) because of the acceleration, massification, flexibilisation, diffusion, and expansion of transnational flows of people, products, finance, images, and information. Therefore, first we are red ink to observe how economic factors of globalization free market, increase power of multinational corporations affect the state sovereignty.The end of the World War Two and the nipping War led to a more open world preservation market to countries and individuals as a result of globalization. Therefore, outside(a) trade between countries increased significantly where foreign direct investments and multinational corporat ions enrold too. Since there was an open free market some countries reached gross domestic product as never seen before. For event, a drastic changes can be seen in countries such as France where the GDP export ration rose almost four times and in the United States where it doubled (Michie, 2011, p.30-40). Michie (2011, p.40-43) also mentions that these manakins show us that multinational trade has grown with time leading to economic dependency between countries which weaken state sovereignty. This dependency gives the power of other countries to manipulate and control the economy of another country. For example, in order to attract more consumers for its goods and services, China taints US bonds to maintain the US dollar currency high. This de-escalates states sovereignty, because it undermines the absolute power of a state over internal and foreign affairs within its own boundaries (Wang, 2004, p.474-76). In this sort US is dependent on China to buy their bonds.Multinatio nal corporations and their foreign direct investments are another part of globalization which undermines state sovereignty. The investments only in the developed countries have risen from 17 to 25 percent between 1990 and 2000 which simply shows that the multinational corporations are a big part of the production and manufacturing of goods and services in few countries (Michie, 2011, p.45-50). Furthermore, between 1960s and 1970s there was an increase in foreign direct investments by EU and US multinational corporations which attracted other countries to get have-to doe with too. Strange (1996, p160-80) argues that globalization has increased the powers of multinational corporations making the state sovereignty weaker. Furthermore, Strange notes that the advancements in technology, wider communications, international trade and transportation are separate of the globalization process which is also seen as an impact on state sovereignty. For instance, states do not have full authorit y over individual businesses which operate in the free market economy. As a result of globalization there is an increased competition between international businesses and therefore, state sovereignty is undermined because it questions the power of the state over its internal affairs (Strange, 1996, p181-99).The biggest repugn which state sovereignty is facing even now is international crime. This is when the state cannot protect its citizens from external or internal affairs as for example terrorism. To prevent that governments form inter-governmental organizations. These organizations are not profit organizations and their target is to result concerns and problems that affect the world. Such organisation is the United Nations. A good present example of an international group which pose a threat to state sovereignty is Al Qaeda. As Aydinli (2006, p.35-45) says, the attacks on US and Spain in 2000 undermined their state sovereignty because they were not able to protect their citize ns. On the other hand, in the same year the United States also intervened Iraq and Afghanistan ignoring the United Nations. This could also be seen as international crime because they ignored state sovereignty and beneficial went into these Middle East countries blaming them for supporting terrorism. Despite the fact that the inter-governmental organizations are suppositious to promote peace, sometimes they violate state sovereignty too. For example, in 1999 NATO intervened national Republic of Yugoslavia in order to prevent more humanitarian hurt and more repression and violence against the civilian population (Solana, 1999). This can be seen as an example of countries, members of NATO, trying to stop this humanitarian catastrophe. Although NATOs actions were legal and justified, the government of Yugoslavia undermined sovereignty by putting its own citizens in danger. This contradicts to one of the aspects of state sovereignty in which the state should protect its own populatio n.Another example is Mali. France, which is a key ally in NATO and UN, started a military apparent movement in Mali again the jihadists which led to an intensive airstrikes in order to fold them (Hammond, 2013). In this case NATO affects the state sovereignty because they intervene to protect the people, whereas the state has to govern and protect its own citizens. This intervention might lead to besides violations of human rights or even ethnic conflicts, even though the innovation of this intervention was to stabilize the country. Therefore, as Albala (2005) says, the actions of these inter-governmental organizations undermine the aspects of state sovereignty as they move into other states territory and also participate in the internal and external affairs of the state. Also the international biotic community is currently condemning Russia for undermining the sovereignty of Ukraine. It is unclear if internal sovereignty will be possible. Furthermore, Russia will support prote sts against the new government even if they have to use military power. Russia has also withdrawn their loans from Ukraine making them dependent on Western financial support. At the same time, the territorial integrity of the country is partly at stake as long as pro-Russian part of Ukraine might feel threatened by the clear pro-Western course of the new intermediate government.This can also be seen as another example of undermining state sovereignty.Globalization is not just a threat to state sovereignty, it is more like a threat to culture and national identity. For example, at no point in the history of the EU or error correction code as it was called erasing borders and encounter states have been seriously considered. Despite the fact that the European Union is an inter-governmental organization seeking for peace and development, it opens the borders between the member countries. Free market economy, free trade and immigration have shaped the EU more as one state than an organ ization. That occurs because the open boundaries lead to merging the cultures and national identity is fading away. All this can raise questions to component states whether or not their national identities and state sovereignty are undermined. Moreover, it does undermine the state sovereignty but in a different way throughout international law.International law has been affected by globalization in terms that it makes the international law into a global public law (Garcia, 2005, p.1-2). What it means is that globalization is actually trying to expand the knowledge domain of justice (Garcia, 2005) from domestic to global. An example is the European Union. When a country in the EU wants to make a law, firstly they have to follow the assentments on European Law and regulations. Garcia (2005, p3) says that International h ordnance to individuals are understood within a framework of harm to a states rights. Simply, the state cannot state laws as it wishes and it also has no sovereig n power on internal and external affairsFurthermore, other form of international organizations are the international non-governmental organizations. They start as small community groups where some of them work also with the government, aiming to help where the government is struggling (Baylis, Smith Owens 2011). However, these organizations have spread their work on a global scale and their cultivate has risen. Inter-governmental and international non-governmental organizations have one target which is global governance where transnational actors aim to exonerate problems that affect more than one state. Such organizations are the Red Cross, do International, Oxfarm International. When one of these international NGO goes into a country with a express purpose as for example to give medical help or fight against violence as Amnesty International does in Somalia, they agree not to get politically involved in anyway. If their work is, for example, then stopped by the government wh o accuses them of showing a bias in which they treat and expel them from the country then the NGO can grunt to the UN and ask for support to continue their work. Recently, Amnesty International has requested the UN credential Council to tighten arms control embargo on Somalia (Amnesty International publication 2014). shoemakers last year the UN Security Council allowed Somalia to import small arms and light weapons (Amnesty International publication 2014)). The intergovernmental organization weakens the state sovereignty in that case because despite the fact that they have stabilized the country on first place, their actions have made the government weaker to defend its sovereignty.To summarize, we first looked at what state sovereignty and globalization mean followed by criticism about the influence of globalization over states. We saw how foreign investments by the multinational corporations and the increasing dependency between economics markets as such as the case with United States and China. State sovereignty was undermined because governments became more unstable and lost control over international businesses becoming dependent on them for proving jobs and taxes. This also undermines one of the main principles of state sovereignty which was the absolute power of the state over its internal affairs, citizens and freedom (Martinez, 1996 Wang, 2004, p.473). Globalization has also brought international crime and international organizations which undermine state sovereignty in different aspects. Terrorism as we mentioned weakens the state making it unable to protect its own citizens. Globalization has been also seen to undermine national identity and state values as with European Union where the European Supreme Court acts as highest law within the European Union. Since some governments cannot guarantee protection there are inter-governmental and international non-governmental organization such as NATO, Amnesty International, United Nations which interven e to help those countries such as Yugoslavia, Mali and more recently Ukraine and Somalia. Although they have been also seen to undermine state sovereignty because sometimes as with Somalia, the international organizations have even worsen the situation. With all these factors of globalization free market economy, multinational corporations, foreign direct investments, international crime and international law it can be concluded that states sovereignty and control over its territory has declined throughout the years due globalization.BibliographyAmnesty International, (2014) UN Security Council urged to tighten arms embargo on Somalia Press release 04/03/2014 acquirable on http//amnesty.org/en/news/un-security-council-urged-tighten-arms-embargo-somalia-2014-03-04 Last accessed 05/03/2014Albala, N.
