Aircraft noise is a significant concern to communities near airports, and therefore a constraint to the growth of aviation. Advanced noise abatement approach and arrival procedures have been shown in previous studies and in limited implementation to be a cost effective means of achieving near- and medium-term noise reductions. Additionally, these procedures can be employed to reduce fuel bum, emissions, and flight time. However, because of aircraft trajectory variations due to operational uncertainties, it is difficult for air traffic controllers to predict and maintain separation between aircraft. Thus, without proper decision support tools, controllers need to add arbitrarily large buffers, thereby reducing airport throughput. A design and operational framework is proposed to advance the implementation of noise abatement arrival procedures. Under this framework, a target spacing is given at an intermediate metering point to ensure with a certain (limited) probability that the remainder of the noise abatement arrival procedure may be completed without further controller intervention. Small probability exceptions are handled by alternative plans.; (cont.) A design methodology is presented, along with the details of a unique Monte Carlo simulation-based Tool for the Analysis of Separation And Throughput (TASAT) that is used to determine the minimum possible target spacing between aircraft at the metering point. Hence...

Supply chain risk has become a major area of concern for companies in the agribusiness sector, as well as for their customers, financiers, and external stakeholders. The threats that environmental and social (E and S) risks pose to brand values and product quality are making those risks more material, often reaching thresholds of major importance to the core business of agriculture and food companies. This good practice handbook is intended for those agro-commodity companies that want to better manage supply chain E and S risks. Agro-commodity supply chains often stretch over multiple supplier companies and multiple countries. Through its eight performance standards on E and S sustainability, the International Finance Corporation (IFC) requires its clients to identify, avoid, mitigate, and manage E and S risks and impacts as a way of conducting sustainable business. IFC recognizes that there is a broader range of significant E and S risks in agro commodity supply chains beyond these four core areas, and the approach set out in this handbook can be applied beyond these areas. The handbook focuses on five major agro-commodity supply chains- palm oil...

Understanding the role of human capital is one of the key considerations in delivering and sustaining competitiveness. Managing employees in the hospitality industry is particularly a challenging task as the industry is considered to be labor intensive. High turnover and increasing employee demands are among the problems that are identified as threats to maintaining a strong competitive position. Successful hotels attempt to retain their best employees in an effort to adapt to changing environments and increased competition. Effective hotel human resource systems can produce positive outcomes, through effective employee retention strategies that focus on work force motivation, attitudes and perception. The positive implementation of these strategies can influence and create employee satisfaction. This study aims to focus on the relationship between the mediating variables of motivation, attitudes, perception and their effect on employee satisfaction. These findings are based upon an extensive survey carried out between April 2009 and June 2009 in the small mountainous state of Uttarakhand, located within the Indian sub-continent. Although the area of study is confined to the Kumaon region of Uttarakhand, the authors contend that the findings and implications can be applied to other remote developing tourist destinations in other regions.

Botswana has recently garnered analytic attention as an anomaly of the “resource curse” phenomenon. Worldwide, countries whose economies are highly skewed towards a dependence on the export of non-renewable natural resources such as oil, diamonds and uranium, have been among the most troubled, authoritarian, poverty-stricken and conflict-prone; a phenomenon widely regarded as the “resource curse". The resource curse explains the varying fortunes of countries based on their resource wealth, with resource-rich countries faring much worse than their resource-poor counterparts. However, Botswana, with diamond exports accounting for 50percent of government revenues and 80percent of total exports, has achieved one of the fastest economic growth rates in the developing world in the last 50 years. Furthermore, the Freedom House ranks it as the safest, most stable, least corrupt and most democratic country on sub-Saharan Africa. In attempting to answer why Botswana apparently escaped the “resource curse”, this research assumes that both formal and informal institutions within the state acted as intermediary variables in determining its fortune. This research thus addresses the deeper question of where Botswana obtained its unique institutional quality that facilitated its apparent escape of the resource curse. It traces Botswana’s history through four lenses: legitimacy and historical continuity...

Introduction: On January 12, 2010, an earthquake of unprecedented scale shook the small Caribbean nation of Haiti. The epicenter of the earthquake, which measured 7.0 on the Richter scale, was approximately 25 kilometers west of Port-au-Prince. The earthquake killed an estimated 222,570 people and left 3.7 million people affected one way or the other.1In the summer of 2010, 1.5 million internally displaced persons (IDPs) were in camps distributed across Port-au-Prince.2That summer, the International Organization for Migration (IOM), an intergovernmental organization dedicated to the humane and orderly migration, undertook a project in Haiti which involved placing suggestion boxes in IDP camps and inviting the displaced to voice their concerns, hopes and dreams. Given the opportunity, the traditionally under-served and under-represented displaced Haitians dropped letters in IOM’s suggestion boxes by the thousands (approximately 2,500). The name of this project was Voice of the Voiceless. The project was the first serious attempt in the country to provide a voice to those who were displaced by the earthquake. Voice of the Voiceless letters (both the hard copies and the digital copies) will soon be housed at the Special Collections of the Florida International University (FIU) Libraries (see Letter of Support from Mr. Leonard Doyle...

This thesis examines how skin bleaching can be understood within the cultural context of Jamaican dancehall. I argue that as a cultural practice, skin bleaching can be viewed as a critique of the concomitant structural inequalities precipitated by colorism, which is a by-product of racism. In proposing skin bleaching as a queer performance of color, I attempt to illustrate the manner in which the lightening of the skin exposes the instability of racism and colorism as socially constructed, discursive regimes. If race and skin color are biological and embodied facts dictated by social reality, then bodies, which are racially marked and colored subjects, can be used to project counter discourses that challenge these specific regimes. The space of discursive limit imposed on the racialized or colored body-subject is a space from which critiques of dominant discourses can be projected, and bleaching does precisely that. I conclude therefore, that skin bleaching is performed resistance which challenges the dominating discourses on race by first destabilizing the notion that skin color is an immutable biological fact, and second by contesting subsequent discourses that are contingent on the “facts” of color and race.

Commercial fisheries in the Florida Keys have experienced a significant decline in participation and harvest over the past two decades, with over half of the fishers exiting the fishery since 1990 and a 50-70% decline in annual landings compared to previous decades. The conventional narrative of fisheries management identifies overfishing and overcapacity as the malaise endemic to open-access fisheries systems, for which the remedy offered is technocratic management. Technocratic management, which seeks to restore ecological integrity and economic efficiency, has been increasingly employed in the Florida Keys, in the form of limited access and property rights measures. I contend that the technocratic management approach is flawed and in a large part responsible for the decline of Florida Keys fisheries because the approach has ignored social sustainability, leading to a significant reduction in fisher participation, the fragmentation of fishing communities, and erosion of social capital. Technocratic management has also underestimated the importance of non-fishery factors, unique to place, and these factors – including population, tourism, and globalization factors – have exacerbated the impacts of management measures. The net result has been the opening up of scarce and valuable coastal space...

This dissertation examined the effect of United States counter-drug policy on nationalism in small states, focusing on Jamaica and Trinidad and Tobago. The states were selected for their roles and geostrategic importance in the illegal drug trade; Jamaica being the largest drug producing country in the Anglophone Caribbean and having strong links to the trade of Colombian cocaine, and Trinidad being a mere seven miles from the South American coast. Since U.S. counterdrug policies have frequently been viewed in the region as imperialistic, this dovetails into ideas on the perceptions of smallness and powerlessness of Caribbean nations. Hence, U.S. drug policies affect every vulnerability faced by the Caribbean, individually and collectively. Thus, U.S. drug policy was deemed the most appropriate independent variable, with nationalism as the dependent variable. In both countries four Focus Groups and one Delphi Study were conducted resulting in a total of 60 participants. Focus Group participants, recruited from the general population, were asked about their perception of the illegal drug trade in the country and the policies their government had created. They were also asked their perception on how deeply involved the U.S. was in the creation of these policies and their opinions on whether this involvement was positive or negative. The Delphi Study participants were experts in the field of local drug policies and also gave their interpretations of the role the U.S. played in local policy creation. Coupled with this data...

This paper offers a causal analysis of the conflict between the Kurdistan Workers’ Party (PKK) and Turkey that has been ongoing since 1984. The history of Kurdish politics in Turkey is investigated in order to uncover the conflict’s causes. The conflict’s origins in the Turkish state’s refusal to recognize Kurdish identity and its forced attempts to assimilate Kurds into Turkish society are examined. Other causal factors such as the political turmoil of the decades prior to the conflict’s initiation, the involvement of the student youth in politics, the rise of the PKK, and the interrelationships between the causal factors are also analyzed. Further discussion on the conflict’s influence on sociopolitical and interstate motivations and how the causes of this conflict compare with other conflicts is provided.

Plagued with poverty, the countries of the Caribbean have grappled for years with numerous development models. As in many Third World countries, tourism has been used as an economic development strategy. Criticisms of the tourism industry have frequently been severe. So much that during the formation of the Caribbean Basin Initiative, the tourism industry was intentionally avoided and other industries favored. One of the most critical questions asked of tourism is whether or not the economic gains of the industry are worth the detrimental social, political and environmental effects on the host country. It is the objective of this thesis to examine the relationship between international tourism and socio-economic development in the Caribbean, and to determine whether or not the deficiencies of the industry prevent it from being a beneficial development tool.

Developed countries give foreign assistance for many reasons, one of which is the protection of national interests. Foreign aid gives a donor country leverage in international relations and is used as a tool of foreign policy. The United States and Japan are the two largest aid donors in the world. Each of these countries exert influence over specific regions through foreign assistance. Although the national interests of each country are different, both use foreign aid to protect these interests. This thesis discusses the means by which the United States and Japan use foreign aid in foreign policy. It looks specifically at U.S. food aid to Central America and Japanese aid to Asia.

When speaking of international criminal law, it is assumed that this system is of Western origin. The fact that concepts of human rights and a common international standard regulating these rights existed in Islam centuries (about 1409 years ago) before Western case law, the Universal Declaration of Human Rights, and the United Nations body existed is largely unrecognized. This research examines whether Islamic international criminal law and Western international criminal law are compatible, and analyzes the possibility of applying principles of Islamic human rights and justice universally. The analysis of primary textual material, mainly the Quran, supports the major arguments of my thesis. Evidence presented refutes competing explanations of Islamic international criminal law as being in contradiction to international law and human rights norms. On the contrary, Islam and human rights are not only compatible, they are more so inextricable from each other. I take the position that it is not Islam which should be reformed, but rather it is the Muslim people who must reform their understanding of Islam and revert to observing the mandates of their religion, thus living up to international standards.

Many U.S. students do not perform well on mathematics assessments with respect to algebra topics such as linear functions, a building-block for other functions. Poor achievement of U.S. middle school students in this topic is a problem. U.S. eighth graders have had average mathematics scores on international comparison tests such as Third International Mathematics Science Study, later known as Trends in Mathematics and Science Study, (TIMSS)-1995, -99, -03, while Singapore students have had highest average scores. U.S. eighth grade average mathematics scores improved on TIMMS-2007 and held steady onTIMMS-2011. Results from national assessments, PISA 2009 and 2012 and National Assessment of Educational Progress of 2007, 2009, and 2013, showed a lack of proficiency in algebra. Results of curriculum studies involving nations in TIMSS suggest that elementary textbooks in high-scoring countries were different than elementary textbooks and middle grades texts were different with respect to general features in the U.S. The purpose of this study was to compare treatments of linear functions in Singapore and U.S. middle grades mathematics textbooks. Results revealed features currently in textbooks. Findings should be valuable to constituencies who wish to improve U.S. mathematics achievement. Portions of eight Singapore and nine U.S. middle school student texts pertaining to linear functions were compared with respect to 22 features in three categories: (a) background features...

The object of this dissertation is to record and analyze the foreign policy of the Sultanate of Oman from the early twentieth century until 2004. It challenges the central assumption of the contemporary scholarship on the subject that Muscat's modern foreign policy begins in 1970. It is often presumed that the pre-1970 era does not merit a thorough investigation to understand Muscat's modus operandi today. This study argues that for a comprehensive understanding of Muscat's foreign policy since 1970, the frontier of the historical analysis of Oman's regional and international involvement should be pushed back to the 1930's, when the young Sultan Said assumed power over the country divided by the "Treaty" or the "Agreement" of Sib. Indeed, the thrust of this research lies at once in repudiating the conventional wisdom regarding both the persona of Sultan Said and the customary political/historical narrative of Said's reign. The critical analysis of this period is utilized to rebut the pervasive and largely inaccurate historical narrative of the events prior to 1970, to recount an original interpretation of the period, and to use the narrative as a preamble for subsequent foreign policy directions and initiatives. Furthermore, this dissertation covers the gaps in the literature resulting from the absence of any materials that either record or analyze Muscat's foreign policy from 1996 until 2004. In addition...

French-speaking countries in West Africa have a long history of inter-state cooperation that goes to the French colonization of the region. The culmination of their integration resulted in the creation of L'Union Economique et Monétaire Quest Africaine, UEMOA (The West African Economic and Monetary Union). With its financial and monetary arrangements, which include a common currency and a central bank, UEMOA is one of the most far-reaching examples of economic integration among developing countries. UEMOA's main advantage has thus been its "depth." What makes the study of Francophone regionalism in West Africa even more interesting at this particular time is the fact that it is taking place within the context of a new wave of integration characterized by a trend towards broader regional integration in West Africa. The efforts towards broader integration in West Africa are reflected in the activities of the Economic Community of West African States (ECOWAS). ECOWAS has been able to engage in integration activities in a broad range of sectors. The existence of the two integration schemes has raised questions regarding the chances for the successful accomplishment of regional integration in West Africa. More specifically, UEMOA has been seen as posing an obstacle to the progress of the larger sub-regional grouping of ECOWAS. In this study...

The International Coffee Agreements (ICA) involved the majority of nations producing and consuming coffee and provided relative economic stability to the coffee sectors of the exporting Third World countries. This study focuses on the serious impact of the 1989 collapse of the ICA on the domestic coffee sectors of Colombia and Cote d'Ivoire. In particular, the dissertation examines the role of the Colombian and Ivoirian coffee parastatals, the Federacion Nacional de Cafeteros de Colombia and the Caisse de Stabilisation et Soutien des Prix des Produits Agricoles, during the crisis and their transformation by it. The theoretical framework employed in this study is borrowed from the literature on state-society relations. The methodology includes: in-depth analysis of the historical roles of the parastatal agencies in coffee production, state-society relations and economic development in Colombia and Côte d'Ivoire; interviews with parastatal administrators, producers and other knowledgeable informants in both countries; and a comprehensive review of newspaper articles and official statements of coffee policy published in Colombia and Côte d'Ivoire prior to, during, and after the crisis. The Colombian and Ivoirian coffee sectors and their producers faced serious economic and social problems following the drop in coffee prices. The coffee parastatals in Colombia and Côte d'Ivoire first lost some of their responsibilities following the world coffee crisis. The Caisse was in the end eliminated while FEDECAFE struggled to remain in existence. Along the way...

This thesis examines the involvement of the United States in the decade-long trade dispute before the World Trade Organization (WTO) over the European Union's preferential banana regime. Washington's justification for bringing this case to the WTO comes from Section 301 of the U.S. trade act, which allows for disputes to be undertaken if U.S. "interests" are violated; however, this is the first case ever undertaken by the United States that does not directly threaten any American banana industry, nor affect any American jobs. Why, then, would the United States involve itself in this European-Caribbean-Latin American dispute? It is the contention of this thesis that the United States thrust itself headlong into this debate for two reasons: domestically, the United States Trade Representative came under pressure, via the White House and Congress, from Chiquita CEO Carl Lindner, who in the past decade donated more than $7.1 million to American politicians to take the case to the WTO. Internationally, the United States used the case as an opportunity to assert its power over Europe, with the Eastern Caribbean islands being caught in the economic crossfire. According to existing literature, in undertaking this case, the United States did as any nation would: it operated within both domestic and international levels...

In recent years the People’s Republic of China has begun to exhibit a more aggressive naval policy as a result of its decision to switch its naval force from a primarily green-water fleet (coastal) to a blue-water fleet (expeditionary) (“China’s New,” n.d.). This decision has brought China to loggerheads not only with other local East and South Asian powers such as India and Japan, but also with the predominant blue-water power of the world, the United States, that sees its supremacy threatened (“When Grand,” n.d.). Why would China embark on a route that would pit it against the world naval superpower, the United States, which has a huge lead on China in terms of naval blue-water power? Why would China try to challenge and match the U.S. Navy’s eleven aircraft carriers (“The World’s,” n.d.)? What could compel China to embark on a plan that would so disrupt the balance of power in the waters around Asia? To fully understand the Chinese government’s decision, one must first look at Chinese import figures and Chinese trade routes.

Access to basic services plays an important role in both individual well-being and a country's economic development. For this reason, general availability of these services to citizens, regardless of income level and geographical location, has generally been viewed as an important public policy goal. However, the precise definition of this goal and the means of attaining it have provoked controversy. This volume explores whether liberalization can contribute to achieving universal service goals and, if so, how, and looks at the types of complementary policies that may be required. It focuses on experience in four sectors: telecommunications, financial, water and sanitation, and energy services. For each sector, an overview paper and one or two case studies from developing countries examine the experience of governments in harnessing liberalization to meet social goals. It is hoped that this cross-sector view will yield general insights which a focus on a single sector may not, and help each sector to generate ideas by drawing upon experience in other sectors. A horizontal assessment also helps to determine how far the services negotiations at the World Trade Organization (WTO)...
