Undecided - Research Paper Example During this process, water becomes produced first from the fractures present within the coal. This process continues until the pressure declines to the level where methane would begin to desorb from the coal surrounding substance itself. The extent of the coalbed fracture stays controlled by the characteristics of the geologic formation, the fluid used in fracturing, and the pressure employed in pumping. The distance at which the fracturing would be performed also comprises geological formation characteristics. The ability for a fracture to grow taller or longer would be determined by the material goods of the surrounding rock. A hydraulically generated fracture would take the route of least resistance through the surrounding rock formations and coal seams (EPA Chapter 1; 3-4). Studies by the Environmental Protection Agency (EPA), Marcellus Shale Team, and the Energy Institute have clearly confirmed the effectiveness of present-day state regulations in protecting water resources. Thi s research paper positions itself to supporting that methane hydraulic fracturing fluids into coalbed wells pose a minimal threat to underground drinking water sources. Discussion EPA conducted a research study into evaluating the impacts of hydraulic fracturing of coalbed methane to underground sources of drinking water. The study employed a methodology covering hydraulic fracturing processes and potential incidents of water quality associated with the process. Also, the methodology would determine hazardous constituents contained in hydraulic fracturing additives and fluids as well as identification of coalbed methane basins hydrogeology. The approach employed a detailed and extensive collection of reviews and information of theoretical and empirical data. EPA also reviewed cases of underground drinking water contamination alleged to have resulted from the injection of methane hydraulic fracturing fluids into coalbed methane beds (EPA Chapter 2; 2). Methane hydraulic fracturing fl uids include foamed gels, acids, potassium chloride water and clear water, cross or linear linked gels and a combined treatment of any two or more of these fluids. On the other hand, hydraulic additives include biocides, friction reducers, breakers, acid corrosion inhibitors and fluid loss additives (EPA Chapter 4; 2-8). Their findings on water quality incidents reflected data from formal studies, in addition to the opinions of, residents living near coalbed methane sites namely Black Warrior, Powder River Basins, San Juan and Central Appalachian. Incidences of contamination could be attributed to common production activities such as surface discharge of fracturing and production fluids, and methane migration through fracturing and drilling made outlets. In addition, contamination could arise from improperly abandoned production well, aquifer dewatering and poorly installed or sealed production wells. Moreover, natural factors, resource development, historical practices and populati on growth also constitute potential sources of contamination to drinking water. However, the follow-up outcomes of the study concluded that underground drinking water sources could not be contaminated by hydraulic fracturing. According to EPA, the production of ground water would minimize the likelihood that chemicals contained in fracturing fluids could impact negatively on underground drink

As the truth carefully unfolded, one could not help but feel disappointed and disgusted that a nation such as the Soviet Union could fabricate events and continue to mislead the public into the truth that happened within the labor camp. Suffice it to say, millions died due to diseases and malnutrition, rather than putting the blame on homicidal gassings that never occurred. The interview with Dr. Piper, the Head of Archives at the Auschwitz State Museum validated cover-ups and exposed falsified published information that contributed to the world’s indignation and anger towards the Nazis during Hitler’s regime. The presentation was clearly created and vividly revealed that people continue to mislead others for personal interests and hidden selfish agendas. However, despite the revelation, the truth of the matter per sists that still more than one million Jews died in those trying times when they could have been accorded the same human rights as those of their

Kinship Organizations Essay Example | Topics and Well Written Essays - 750 words

Kinship Organizations - Essay Example The Kinship System and Culture of Yonomamo Their social life is organized around the respected tribesmen, where kinship relationship descent from ancestors and marriages between these kinships. According to Webster (2004), the tribesmen are given responsibility to maintain order in the villages and determine the village’s relationships with people of other villages. The tribesmen are given these positions owing to kinship and marriage customs, and it depends on the main kinship groups in the villages they come from. Webster (2004) indicates that the social changes within Yonomamo villages are based on giving and receiving marriageable girls in society. Thus, marriages are arranged by order kin, who include uncles, brothers and fathers of the spouse. Marriage in Yonomamo is based on the political process where girls are promised marriages while their extremely young, and men involved forms alliances with other men via marriage exchanges. There is inadequate of women in the Yono mamo due to the sex ratio imbalance in the younger ages that result in men having more than one wife. In case of fighting in the village, this is as a result of sexual relationships and attacks done to married women by other men. Meanwhile, the fight can cause internal fighting and conflicts of such greatness that lead to splitting and fission of villages, and create new villages. Yonomamo have a series of quality forms of violence that include club fighting and chest pounding that prevent severe violence like shooting to kill. This offers them a great deal of flexibility in resolving the conflict without immediate resort to deadly violence (Webster, 2004). Meanwhile, they have incorporated patterns of alliance and friendship that serve to limit violence these include trading and feasting with others in order to promote friendships. According to Webster (2004), the thin line between friendship and hostility must be controlled by village leaders whose political acumen and strategies are both admirable and complex. The Yonomamo have developed one unique language that each community speaks in variety version of this language. Traditionally, they had no written language, but depended on the same words to describe several different things. For instance the Yonomamo word â€Å"Xawara† can mean disease, gold and epidemics at the same time; thus, they communicate by chanting, telling stories and using lively expressions. The Yonomamo culture does not have political readers or police force to keep law and order. However, they depend on village leaders, who do not have power over anyone, but are allowed to make suggestions about matters of daily activities. Children are an essential part of the Yonomamo culture that means the more children living in a village; the more they assisted with household tasks. To increase chances of having many, men are allowed to marry many wives that give the family a better chance of continuity. Moreover, the ceremonies are another significant part of the Yonomamo culture, and they are carried for many reasons and used to communicate with spirit. Webster (2004) indicates that ceremonial hunts may be introduced to practice catching a specific animal and they usually take part with the whole family. Meanwhile, they travel to other villages to share stories and socialize with other groups; thus, family and relationship are a significant part

Synchronized Access to Shared Memory by Multiple Essay

Synchronized Access to Shared Memory by Multiple - Essay Example Various techniques which can be used to achieve this are discussed in the following paper. A multi-core processor (or chip-level multiprocessor, CMP) combines two or more independent cores (normally a CPU) into a single package composed of a single integrated circuit (IC). The below diagram "Dual CPU Core Chip" (Schmitz, 2004) gives an idea about it. The principle behind current Multi-Processing (MP) systems is that computations requiring large amount of CPU usage could be broken up into many relatively independent parts. These parts, called threads, while being executed simultaneously, could either be of the same or different process. Since these threads could be inter-dependant, issues of memory architecture and in particular memory consistency and cache behavior are 'key' to both correctness and performance in multi-processing systems. Multi-Core Processors (CMPs) could be broadly classified as Uniform Memory Access (UMA) processors in which all the CPUs are able to access all the memory with no specific preference or Non-Uniform Memory Access (NUMA) processors, where each CPU may have its own special memory area. A system may maintain memory consistency using hardware or using a combination of hardware and software techniques. Hardware can provide a particular memory ordering guarantee, (hardware will maintain the sequential nature of program memory accesses), while software can be used supplement hardware-provided memory ordering by forcing additional ordering restrictions at desired times. The memory ordering scheme implemented is a design choice involving a tradeoff between hardware complexity, software complexity, and the desired ability to cache and buffer data. Non-Uniform Memory Access (NUMA) Architecture Refer Diagram "NUMA Architecture." (Watson, n.d., p. 4) In NUMA architecture a processor can access its own local memory faster than non-local memory that is, memory local to another processor or memory shared between processors. In this type, all the MPs may or may not be of similar capacity (Asymmetric Multi Processing). Communication between processors is often based on use of shared memory between those processors. An 'Inter Process Interrupt' (IPI) allows CPUs to generate notifications to other CPUs to invalidate entries for a shared region or to request termination. Uniform Memory Access (UMA) Architecture Refer Diagram "UMA Architecture." (Watson, n.d., p. 3) When multiple processors can access the same shared memory, the MP system has to make sure that the ordering of memory access from one processor is made visible to the other processors. Memory Fencing One way to achieve 'Cache Coherence' in a MP environment would be by using 'Fencing' technique. Refer Diagram 'MFDA and MFDR Instruction" (Mittal, 1997, p. 26). In this technique, MP system (11) access and release of shared memory space (15) is done using two special instructions - MFDA and MFDR. The Memory Fence Directional - Acquire (MFDA) (16) instruction locks the specified area from being accessed by other processors. Once the operation is over and data can be released, the Memory Fence Directional - Release (MFDR) (17) instruction is issued. Since an MFDA instruction 'locks' the shared data until its

To What Extent is BP Guilty of Greenwashing Literature review

To What Extent is BP Guilty of Greenwashing - Literature review Example The Concise Oxford English Dictionary defines 'greenwashing' as "disinformation disseminated by an organization so as to present an environmentally responsible public image." It is argued that the presence of the word in the dictionary indicates the growing trend of this phenomenon among corporations. The trend of 'greenwashing' seems to be on the rise as oil companies, known to reap heavily from degradation of the soil, pollution of the air and global warming, realize that they have to re-present themselves as partners towards global climate solutions, manufacturers of automobiles, jets and airplanes realise they can launder their image even as they promote their products and companies in all industries realize the importance of presenting their activities and products as climate-friendly, to make socially conscious investors and consumers more comfortable with buying their products. In most cases, the 'green' propaganda is also aimed at achieving an unfair advantage over competitors (BP's Rebranding,2005). Deen (2002) reports that the wave of 'greenwashing' began more than a decade and a half back, in 1990, when on 'Earth Day millions of people across the world gathered to protest the declining health of the planet. This made it glaringly clear to the several multinational corporations that the average human had started to take interest in the wellbeing of his environment. British Petroleum (BP)... The company also owns 23 refineries and 32 chemical manufacturing plants around the world (BP's Rebranding, 2005). In mid-2000, BP launched one of the most expensive public relations and advertising campaign in recent times, representing the company as an environmental-friendly one and introducing a new slogan 'Beyond Petroleum'. In line with the campaign, the chief of the company was quoted as saying; "The time to consider the policy dimensions of climate change is not when the link between greenhouse gases and climate change is conclusively proven, but when the possibility cannot be discounted and is taken seriously by the society of which we are part. We in BP have reached that point". During the course of the campaign, BP touted itself as the global leader in producing the cleanest burning fossil fuel, the first company to introduce cleaner burning fuels to many of the world's most polluted cities and the largest producer of solar energy in the world (BP's Rebranding, 2005).

Health Care Communication Methods Essay Example for Free

Health Care Communication Methods Essay Every day in the health care field, professional have to choose the most effective communication method when communicating to other professionals, patients, patient families, and the general public. Different circumstances have very specific methods of communication that need to be utilized for communication to be effective. Furthermore, in the health care field the regulations of HIPAA have to be considered to ensure that certain information is being protected as well as identity of people pertaining to the health scenarios. Further will be discussed the methods of communicating in the health care field, the advantages and disadvantages of using traditional, electronic, and social media for health care communicating, and the effects of HIPAA and other regulations on the use of media in the health care field of communicating. Communication coordinators of any health care field have to decide often which methods of communication he or she would have to utilize and the rules and regulations that govern those methods. In one scenario, a communication coordinator that works for a national drug manufacturer has received report that there has been a report of significant negative side effects caused by one of the medications that is used by a large population of people and one including a well-known public figure. News reports having been reporting that of the possible individuals who have been taking this particular drug is effected by the side effects. The communication coordinator has to decide how to address the news reports and the general public about this situation. There are many different ways to communicate with the general public regarding the scenario described. As mentioned before the communication coordinator has to reach out to the general public regarding a medication that was distributed by a national drug manufacturer company that lead to significant side effects. Some of the different methods of communication using media are campaigns, medical journals, news reports, blogs, and other social medias. For the specific scenarios described previously it would be best to use the ampaign method. A campaign would be used to increase awareness, create a better understanding, modify attitude, and modify behavior (Health Industry Communication, Ch. 5). This method may be used when reaching out to a significant sized population. â€Å"The communication program will target whom, to help them understand, believe, or do what, by informing them of messages, through messengers and channels, to result in objectives† (Cheesebro, T. , O’Co nnor, L. , Rios, F. , 2010, Ch. 5). The objective of utilizing the campaign method would reach out the larger population through possibly multiple different media methods, instead of just one or two. When considering using different types of media and which ones to include and exclude when communicating through media, it is important to consider the advantages and disadvantages of traditional, electronic, and social media. Traditional communication methods are the most common methods of communicating. This includes newspaper, journals, magazines, television, radio, and etc. While this might be considered one of the most effective methods compared to electronic and social media, there are disadvantages as well as advantages of traditional communication. One advantages of using traditional communication methods is this can reach a larger population which would then decrease the time it takes to reach the population by some other methods of communication. Another advantage of using traditional communication method is a larger part of the population uses this as resources to gain information for different point of interests. One disadvantage of using traditional communication methods is that it can be costly compared to some other communication methods. â€Å"Traditional medias have a high effect in creating awareness and influencing the attitude of the audience† (Tiwari, Singh, Tiwari, 2003, p. 2). Electronic communication method also can be an effective way to communicate to the general public. Electronic communication includes email, phone calls, text messaging, video calling, and etc. Although not every method of electronic communication would be considered effective for scenario previously described, some such as email would assist with retrieving audience attention. Just like any other communication method, electronic communication method also has its advantages and disadvantages. An advantage of electronic communication method is it creates direct communication methods to the intended audiences which can begin to change audience attitude towards a circumstance before any other communication tactic takes into effect. One disadvantage of using electronic communication is there is a large section of the population that does not have access to electronics such as computers and internet. This population does not also have access to email and may not have easy access to a phone. Those people would then be more difficult to reach out to (Tiwari, Singh, Tiwari, 2003). Another disadvantage may be the low literacy and language barrier of the population. Social media communication method is another way to communicate to the general public under different circumstances. Social media communication includes social sites such as Facebook, Twitter, online video sharing, podcasts, blogs, and etc. Although this may be an effective way to communicate to the public, there are advantages and disadvantages that come with social media communication. According to CDC (2011), In the last several years, the use of Facebook, YouTube, Twitter and other social media tools to disseminate health messages has grown significantly, and continues to trend upward. Using social media tools has become an effective way to expand reach, foster engagement and increase access to credible, science-based health messages† (4). This also has an advantage because it reaches a larger population at a faster rate and costs less than some other methods of media communication. A disadvantage of using social media method in communication is the credibility of the resources may be still questioned by a large portion of the population. Another disadvantage of using social media communication is it may not reach all of the population to whom the topic is regarding. HIPAA plays a significant role in media communications. The essential functions of HIPAA regulations protect the privacy rights of patients and its users. When communicating health information, all health providers and any participants of health communication must ensure that the facts they wish to release are authorized and as accurate as possible (Nhanet, 2012). Any information released about any patients must be authorized by patients through written authorization and must follow federal and state guidelines. HIPAA prohibits any person communicating about health to public to disclose any information about patients even if it is general speaking of the patient. According to Hader and Brown (2010) â€Å"Healthcare providers using social media must remain mindful of professional boundaries and their patients privacy rights† (p. 1). In conclusion, communicating through different media methods can be a useful source to communicate effectively to the public. Some methods are better than other, however all methods have different advantages when communicating to the public. There are also many disadvantages that are to be considered when implementing each method. There are also HIPAA regulations that have to be followed when communicating about patients or to patients regarding any facts and issues. The media is a way to communicate to a significant sized population when HIPAA laws are followed.

Major Roles Of Development Studies Politics Essay

Major Roles Of Development Studies Politics Essay We live in an unequal world: one part of the world is suffering from hunger, poverty, high child mortality rates, mortal diseases and numerous other grave issues; the other part of the world benefits from high income rates, very good health care systems, excellent educational institutions and superior standards of living. Progressively, many international institutions and non-governmental organizations have taken a stand against this inequality and they continuously seek to develop the world into a better place with better standards. These organizations believe they can make a change by supporting underdeveloped countries and by coming up with measures and goals for the whole world in order to try and stop the biggest threats to further development. Development Studies is, in fact, one of the recent and most important branches of political science nowadays. It is through Development Studies that one can understand the tragic imbalance of the world, and come up with solutions to tackl e the issues threatening development. Therefore, research and statistics form a major role in Development Studies; by carrying out specific research, one can identify what is hindering a particular country from further development and what solutions may be applied. Throughout the years, many scholars tried to quantify development and find ways to measure it and undoubtedly the most successful instrument for development existing today is the one named Human Development Index (HDI). While many believe that this is the best system and the best indicator vis-à  -vis global development, some others believe that there is still much more to be done, and that the HDI might still need some adjustments. This paper addresses the issue of development in todays unequal world, as well as presents all the arguments in favour and against the use of HDI as the first and most important tool to measure development. What is Development? Many scholars, politicians and writers use the term development in their studies, talks or books; however, these persons might be using the word in different contexts. For the sake of this essay, it is imperative to give out the definition of the word development as it is going to be used throughout the whole paper. Professor Jeffrey Haynes, successful author and lecturer, defines development as a key dimension of personal life, social relations, politics, economics and culture.  [1]  Development does, in fact, touch many branches of one particular country (economic, social and cultural development); therefore it is made up of various components. Furthermore, Development Studies is a vast and rapidly expanding field of inquiry  [2]  ; as the word itself suggests, development continuously changes it is never static. The components making part of development might increase or decrease throughout the years. It is difficult to set a date to the rise of interest in Development Studies. However, Dr Clark, through his acclaimed book, estimates the origin of awareness in the field of development around the late 1940s and early 1950s  [3]  , when there was an increasing interest in development economics  [4]  . Other scholars, such as Todaro and Smith comment on how the Europeans were unable to reach a certain level of developed economy within their countries a decade or so after, despite the willingness and hard work involved.  [5]   The notion of human development concerns the actual lives and conditions of the citizens of a specific country; Haynes accurately defines human development as a matter concerned with [the] stability, security and citizens relative prosperity.  [6]  Human development treats all of its components on an equal basis, giving them direct value  [7]  . Since development has a vital link with the wealth of a country, this does not mean that it is highly or solely influenced by the national income rates: Human development is about much more than the rise and fall of national incomes. It is about creating an environment in which people can develop their full potential and lead productive, creative lives in accord with their needs and interests. People are the real wealth of nations.  [8]   The importance of global development in the world has gradually increased. Nowadays we know more about development, how to measure it and achieve it. Furthermore, there are numerous organizations and international institutions, such as the UN, who give development a huge significance within their agenda and who continuously give their support to underdeveloped countries and urge the world to support each other out. Measuring Development There can be no improvement in the field of development if proper analysis is not carried out for every single country and region of the world. Good analysis of statistics provides identification of threats to further development and of possible solutions for improvement: The analysis of development goals is part of the analysis of development.  [9]   Therefore, measuring development is a significant step in identifying the development index of a country. The problem still remains on what is considered to be a component in measuring the development of a country. Development indicators can be many: the Gross Domestic Product (GDP) within a country, the Gross National Income (GNI), the life expectancy rate, gross education enrolment rates and more. Many scholars do not agree on what these development indicators should be. There have been numerous conflicting papers written by scholars stating their own opinions on the matter. For example, economist Jan Drewnowski repeatedly states that while economic development indicators contain concrete figures, social development indicators do not possess such precise quantitative results.  [10]  He states that welfare indicators are observable and measurable phenomena and that welfare is not directly measurable, but he also says that although measuring such development indicators might not produce perfect results, it is better than doing nothing at all. Other scholars provide other views; economists Irma Adelman and Cynthia Taft-Morris make a case for a more flexible approach to the measurement of institutional phenomena, which would rely on expert judgment on qualitative rankings.  [11]  12 Throughout the years many scholars and organizations have attempted to come up with an instrument to measure development. Although there is still no existing perfect method of achieving such data, there is one leading collection of data which is continuously cited by organizations and governments alike. This index-list was undertaken by the United Nations Development Programme (UNDP) and is mostly referred to as the Human Development Index (HDI). What are HDR and HDI? The HDI is a result of the Human Development Report (HDR), a report produced every year by the UNDP. The first HDR was published in 1990 while the latest HDR was published last year, marking its 20th anniversary edition.  [13]   Within the report, the UNDP analyses the results of its research in the development field. For example, the 2010 HDR published by the UNDP contained chapters about various branches of development which analyzed either progress or regress on a global level. In the 2010 HDR, one can learn how progress in the health sector has slowed down, while gender differences in the education sector decreased as well. Other examples include the increased (global) levels of education but also the problem of children not learning.  [14]   For better or for worse, the annual HD reports have provided an intrinsic method of measurement of development. One of the highlights of the HDR is undoubtedly the HDI. Most governments, international and national organizations give a lot of attention to the HDI, because it provides a set of ranks and indices attributed to a number of countries in the world.  [15]   The HDI essentially is a figure, ranging from 0 to 1. This is measured by combining indicators of life expectancy, educational attainment and income.  [16]  All countries participating in the HDR are ranked numerically according to this figure. The HDI list in itself is made up of four categories of groups of countries with: very high human development (42 countries in 2010), high human development (43 countries in 2010), medium human development (42 countries in 2010) and low human development (42 countries in 2010)  [17]  . It is through these three basic development indicators that the UNDP was able to produce such a high-quality index: Life expectancy For this particular development indicator, the HDI takes the average life years of a citizen in a specific country during a period of thirty years. For the 2010 HDI, for every country on the list, the life expectancy rate was calculated on the timeframe starting from 1980 till 2010. The minimum value was set at 20 years, whereas the maximum one was set at 83.2 years.  [18]   Education The second development indicator used in the HDI is education, and this is calculated by looking at the average years of schooling of every minor and adult citizen at every level of education.  [19]  This HDI indicator also encompasses the gross enrollment rate of the country; both the people applying for education and the school-leavers are taken into consideration when formulating the education indicator. This indicator, just like the previous one, reflects the regress or progress made in a specific country on a timeframe of thirty years, from 1980 till 2010.  [20]   Income The last indicator for development is income, or the wealth component.  [21]  When carrying out its research and analysis, the UNDP sets the minimum per capita gross national income (GNI) rate at $163 (purchasing power parity PPP) at its maximum income rate at $108,211.  [22]  The minimum rate was actually attained by Zimbabwe in 2008, marking it the lowest income rate in history so far. This income value of $163 means just around 45 cents of income every day.  [23]   It is therefore believed that the key to further development is found in the combination of the above three development indicators. Geometrically, the HDI ranking can be calculated using the following economic formula: HDI = ( 1/3 Life expectancy rate + 1/3 education rate + 1/3 income rate)  [24]   Using this formula, the UNDP was able to create the HDIs of the last twenty years. The following table portrays some results from the 2010 HDI, showing one country from all four categories of the HDI. For every country represented in the table there are the resultant figures of the three main HDI indicators. HDI Rank Country HDI value Life expectancy (years) Mean years of schooling (years) Expected years of schooling (years) GNI per capita (PPP 2008 $) GNI per capita rank minus HDI rank Nonincome HDI value 1 Norway 0.938 81.0 12.6 17.3 58,810 2 0.954 56 Mexico 0.750 76.7 8.7 13.4 13,971 -3 0.785 89 China 0.663 73.5 7.5 11.4 7,258 -4 0.707 169 Zimbabwe 0.140 47.0 7.2 9.2 176 0 0.472 Data source: UNDP 2010 HDI  [25]   As one can clearly see, the leading country in the world with the best possible value was found to be Norway, which attained the HDI value of 0.938. All Norwegian statistics are impressive in all sectors of development. Leading economical countries, such as China and India, do not have such impressive results, with them ranking 89th and 119th respectively. The country ranking last with the worst HDI value in the world is the African country of Zimbabwe, of which statistics contrast severely with those of Norway. In fact, an average Zimbabwean lives up to 47 years and enjoys only $176 GNI per capita. The Arguments in Favour of HDI Since 1990, there have been many scholars and economists who have praised the initiative behind the HDI. In fact, many have considered the HDI as a huge step towards understanding what human development constitutes and what changes are needed. The HDI was first seen as an ideal way to compare one country with another and to find a specific countrys place in the whole world. In fact, this method simplifies the comparison among countries  [26]  , and this can beneficial to all governments in order for them to perform better as countries and states. Consequently, this index is described as instructive  [27]  as its empirical relevance has proved to be very meaningful to [both] UN agencies and governments all over the world.  [28]   Throughout the years, distinguished political scientists have continuously declared that the HDI contributes in terms of multidimensionality  [29]  . Among such scholars, one finds Streeten (1994 and 1995), Desai (1993) and Ul Haq (1998), with the latter saying that HDI can capture many aspects of human life that were not capture before.  [30]   Most positive feedback concerning HDI has been about how the HDI has managed to reflect the human condition in no other way other methods can. The methodology used in HDI has also been described as being relatively simple  [31]  , thus favoring it over other indices such as the Corruption Perceptions Index (CPI) and the Environmental Sustainability Index (ESI); its strength lies in its simplicity: a simple measure is more understandable to the policy-maker and the public.  [32]   The Arguments against HDI The HDI gained a lot of criticism from scholars and economists alike; this chapter will focus on the most famous critiques. Some writers criticized the indicators the UNDP used to measure development and discourage the practice of classifying countries into the three bins,  [33]  while others disapproved of the whole system, labeling it theoretically weak (Srinivasan 1994). Moreover, Amartya Sen was concerned by the difficulties of capturing the full complexity of human capabilities in a single index.  [34]  There are also a few who think that the HDI leaves a lot of questions unanswered and they proposed development indices specific to each and every country (such as an American HDI)  [35]  In fact, the HDI seems to conduct general analysis, ignoring differences.  [36]  37This last argument is also sustained by Hicks.  [38]   The majority of critiques debate on the HDI indicators used. Some of them do not agree on how the UNDP uses these indicators, or on how the UNDP interprets its results. For example, the Task Force on Education and Gender Equality disapproves the use of education enrolment rates, finding them imprecise, and proposes school completion rates instead, defining them a more appropriate indicator of educational output'.  [39]   Some others argue on the lack of HDI indicators. Eric Neumayer believes that there is the need of a greener HDI; he argues that the HDI does not take into account natural resource exploitation and environmental degradation  [40]  Finally, there is also a group of writers (like McGillivray, 1991) who believe that the HDI is redundant, meaning that it provides very little or no insight to its analysis. Conclusion Taking into consideration what has been said on the subject, one cannot deny that the HDI has been influential in bringing forward the concept of development. It has been an impressive advancement from the previous attempts. Using the HDI as the main tool for development presents many advantages for governments, to improve their countries its role has been instructive throughout. However, many critics emphasize the disadvantages of HDI, such as the lack of sufficient insight or efficient indicators. Therefore, one can conclude that while it still stands as the reigning instrument to measure development, the HDI leaves much to be done and that in order to achieve a more efficient result, one has to make amendments the HDI is not [yet] an indicator that can reflect properly the idea that Human Development concept brings in itself.  [41]
