Danyk, Y., et S. Vdovenko. « A CHAIN EFFECTS IN THE CYBER-ACTIONS ». Collection of scientific works of the Military Institute of Kyiv National Taras Shevchenko University, no 64 (2019) : 71–80. http://dx.doi.org/10.17721/2519-481x/2019/64-08.
Texte intégralRésumé :
The article presents the results of research on the features of the hybrid war that occurs in Ukraine and other states in cyberspace. Established role and place of chain effects and asymmetric destructive actions in the field of information and cyber security. Due to the fact that at present energy is the basic industry of national economy and national security of any state, the features of complex destructive cyber-, informational and cognitive actions and influences in cyberspace and through cyberspace are considered on the example of the energy sphere taking into account threats, risks and features of cyber-impacts on systems and objects of the critical infrastructure of the fuel and energy complex. The urgency of ensuring energy security of the countries of the world is increasing, as evidenced by the revision of energy development strategies of the European Union, the United States, and other countries. According to the views of a number of domestic and foreign specialists, energy in the field of economics has become an instrument of geopolitics. The level of national security in general, the pace of structural transformation in the economy, the provision of the needs of the population, social production and defense depend to a large extent on its effective, reliable and sustainable functioning. The use of state-of-the-art computer, information-telecommunication and cyber-tech equipment in state critical infrastructure objects requires the implementation and implementation of measures on cyber security, countering cyberterrorism and providing cyber defense. The most important aspects of these influences are identified, approaches are offered for the development of sound organizational and technical measures to ensure the cyber security of society and the state in modern conditions.

Texte intégralRésumé :
This paper makes a contribution to the analysis of regulatory change, an aspect of the broader theoretical debate initiated by the ‘regulation school’ of economic theorists and others. Unlike much of that debate this paper is focused on an empirical field—telecommunications deregulation—and on questions of market strategy rather than those purely of production. After an analysis of the nature and rationale for regulation there is a focus upon the political and economic processes leading to deregulation in the telecommunications industry in the United Kingdom and USA. Attention is directed to ‘natural monopoly’ and ‘public service’ rationales for regulation and the importance of spatial issues is noted. The deregulatory climate and its effects upon computing and communication are then traced out and it is shown how corporate activity is tending towards ‘quasi-regulation’ to reduce competitive and market-based uncertainties.

Texte intégralRésumé :
The scope of this paper is limited to an overview of mutilingualism in the U.S. from 1980 to the present. During this period, discussions of language diversity in the U.S. have been largely dominated by an effort to exert the hegemony of English. This effort has been brought on by changes in the demographic makeup of the U.S. population and supported by a commonly held belief that the economic strength of the U.S. in the international sphere is declining. A dramatic increase in the number of immigrants from Central and South America and the Pacific Rim, coupled with increasing economic competition from industrialized European and Asian nations, has resulted in widespread support for the exclusive use of English in the U.S. This emphasis on English is seen as a way to minimize the threat of the “foreign” influences that are believed to be undermining both the internal unity of the U.S., and its economic world dominance. Whereas nativism is nothing new in the U.S., its current intensity has been fueled by global aspects of migration and economic trade.

Texte intégralRésumé :
Subject. The article addresses the tax reform of 2017, initiated by D. Trump. Objectives. The aim is to determine the relationship between the total volume of tax revenues to the budget of the U.S. Government and the growth of U.S. GDP in the long run. Methods. To identify the impact of the tax reform on the investment climate in the country and the subsequent GDP growth, we formulate a hypothesis and propose a regression model. The quarterly data from 04.01.1960 to 07.01.2019 serve as a statistical sampling, published by financial departments of the U.S. Office of Management and Budget and the U.S. Bureau of Economic Analysis. The study rests on the econometric analysis enabling to identify the impact of the volume of tax revenues from the corporate income tax and individual income taxes on the level of the GDP of the United States. Results. In the short term, we observe a decrease in tax revenues and a subsequent increase in the budget deficit, in the long term – an increase in business activity of the country, a growth in foreign direct investment, and, consequently, an increase in the GDP. The paper offers a model for assessing the economic growth of the GDP of the United States, in which tax predictors were used in combination with macroeconomic indicators. Conclusions. The experience of the United States and the results of this study may be used by the governments of developing countries and experts in the field of taxation for tax policy development.

Texte intégralRésumé :
Information technology (IT) leaders who do not invest in big data projects may struggle to gain a competitive advantage and business insights to improve performance. Grounded in Kotter’s change and Six Sigma models, the purpose of this qualitative multiple case study was to explore strategies IT leaders use to implement big data analytics successfully. The participants comprised 4 IT leaders from 2 telecommunication organizations in the United States of America, who expertly used big data analytics strategies to promote and maximize competitive advantage. Data were collected from semistructured interviews, company documents, and project-related documents. The collected information was examined by utilizing a thematic analysis approach. Four themes emerged from the data analysis process communication, training, employee involvement in decisions, and teamwork strategy. A key recommendation from these findings is for IT leaders to use successful communication strategies to convey the vision and objectives to all organizational levels. The successful communication-strategy can help evaluate business trends, forecasts, improve overall organizational performance and competitive advantage. The implications for positive social change include the potential for job creation, thus catalysing economic growth within communities.

Oehrle, Elizabeth. « The Economic Accountability of Music Education ». British Journal of Music Education 4, no 3 (novembre 1987) : 223–27. http://dx.doi.org/10.1017/s0265051700006057.
Texte intégralRésumé :
Music education struggles to survive in countries such as England, United States and South Africa because of the lack of financial support, particularly during economic recessions. To counter this unfortunate situation, well-written books and articles have been appeared over the years, propounding the truth that the arts do have an essential place in the balanced education of children, but these well-founded and constructed arguments continually fall on deaf ears. During economic recessions government planners and educational authorities rationalise that they can afford to do away with the arts because these subjects make little or no difference to the economic welfare of the country.Information from the best-seller by Peters & Waterman, In Search of Excellence, reveals that the principle characteristics of the managers of excellent companies in the United States are characteristics that concern the creative process of thinking, creative aspects of personality, creative products and environmental conditions. These companies have a positive effect on the United States economy. As the aspect of education which is best equipped to nurture these characteristics is the arts, then it is reasonable to argue that we can not afford to ‘phase out’ music education.Because education in the United States, England and South Africa is closely linked to the economy, music educators in capitalist countries should begin to argue for the arts from an economic standpoint, as capitalistic societies are orientated primarily toward capital gain. Failing this, we shall have to argue for more fundamental changes in political and economic systems.

Texte intégralRésumé :
The article analyzes economic aspects of the interaction between New Zealand and the United States of America as international actors in the Asia-Pacific region. The substantiation of the importance of the Asia-Pacific region in the foreign policy of the two countries is given. We determined that the economic component is one of the most significant components of bilateral relations. Statistical data for the five-year period (2016-2021) are presented, demonstrating the evolution of economic relations between New Zealand and the United States. We established that the economic policy of the two countries is aimed at continuing intensive international cooperation and implementing a recovery strategy in 2021. We concluded that the "soft power" course used by Wellington would enable the country to achieve significant benefits even more in cooperation with other states and reach qualitatively new levels in the existing system of international relations in the Asia-Pacific region.

Texte intégralRésumé :
The introductory piece attempts to set forth as objectively as possible the economic legacy of the Reagan Administration, with emphasis on its international aspects, and thereby to provide the background for the other articles. Gilpin charts the shift in the 1980s from a supply-side, laissez-faire style policy to one that acknowledges a need for cooperation between the United States and its economic partners. While this has been a responsible and productive change, it has also generated ambiguity as to what the U.S. stance on economic international activity should be.

Texte intégralRésumé :
The effects of the Federal Communications Commission Registration Program of 1977 on the structure of the domestic telecommunications equipment producing industry was evaluated. Econometric analysis and anecdotal evidence were used as the foundation for the investigation.
The major hypothesis of the paper was that the FCC Registration Program of 1977 changed the structure of the telecommunications equipment producing industry from a monopoly to an industry characterized by competition. This resulted in a change in the equilibrium price and output in the market place with price decreasing and output increasing.
The three major component subsectors, i.e., transmission equipment, switching equipment, and customer premises equipment (CPE) were discussed individually and collectively to determine any differential effects. This was particularly relevant because the FCC Registration Program focussed on CPE.
Empirically, the central hypothesis was supported. Also, differential effects in the various subsectors were found.M.A.

Texte intégralRésumé :
Domestic mineral consumption is defined as a net sum of apparent consumption plus embodied mineral contained in net imported goods. The U.S. is a net importer of copper-containing products, such as automobiles, electrical products, and construction and industrial machinery. Embodied copper which is contained in net imports of these products constitute part of domestic copper consumption. On the other hand, the U.S. is a net exporter of sulfur-using/embodying products, such as fertilizers and grains. The sulfur which is contained/employed in manufacturing exported products is not actually part of domestic sulfur consumption. Net embodied U.S. imports (exports) of copper (sulfur) are estimated. For copper, it is shown that domestic U.S. consumption is understated and increasing, intensity of use is constant rather than decreasing, and, in general, forecast increases in domestic consumption of copper are due mainly to embodied copper imports. For sulfur, it is shown that domestic consumption is overstated and declining; domestic intensity of use is also declining. The domestic copper and sulfur industries will be differentially impacted as a result of this increased reliance on overseas markets.

Texte intégralRésumé :
This study examined the determinants of U.S. foreign direct investment (FDI) and exports of processed food. This study also examined the impact of U.S. FDI on U.S. exports on processed food. FDI and export models used for estimation in this study were based on the cost-minimizing production function. The analysis focused on ten countries for the period of 1989-2004. Four of them were Asian countries: India, Japan, South Korea, and Thailand. Six of them were European countries: Belgium, France, Germany, Italy,
Spain, and the United Kingdom. The model was estimated using the two-way error component three-stage least squares (EC3SLS) method. Results from this study show that U.S. FDI and U.S. exports of processed food are complements. Major factors affecting U.S. FDI in the processing industry are GDP, GDP per capita, exchange rate, tariff rate, labor compensation cost, interest rate, and distance. Major factors affecting U.S. exports in the processed food industry are GDP, distance, and GDP from the agri-sector.

Wells, Camille. « Social and economic aspects of eighteenth-century housing on the northern neck of Virginia ». W&M ScholarWorks, 1994. https://scholarworks.wm.edu/etd/1539623857.
Texte intégralRésumé :
This study is an attempt to discern what eighteenth-century houses--their forms, dimensions, internal organization, and external settings--have to contribute to scholarly understanding of colonial Virginia's society, economy, and culture.;Historic Virginia houses usually were built more recently than traditional scholars and popular writers have supposed, and standing eighteenth-century houses are, almost without exception, far larger and finer than the dwellings most colonial Virginians inhabited. Yet even lightly constructed and shabbily finished houses stood at the center of a complex of buildings where most of the planter's household and agricultural work was performed. Thus eighteenth-century Virginia houses were more mundane and unpretentious yet more symbolically and functionally dominant components of the landscape than surviving houses and their isolated rural sites can suggest.;This dissertation employs documentary, architectural, and archaeological evidence to address three questions. What can a close reading of written sources convey about the character and context of houses in eighteenth-century Virginia? What can a close inspection of surviving houses, their archaeological remains, and their associated documentary histories convey about the circumstances of their construction and use, the significance of their form and presentation? Finally, what was the economic background and the social significance of a pretentious Virginia house which was built, accoutred, and inhabited during a time and in a place where such structures were exceedingly rare?

Napit, Krishna Bahadur. « Economic impacts of extension integrated pest management programs in the United States ». Thesis, Virginia Polytechnic Institute and State University, 1986. http://hdl.handle.net/10919/74524.
Texte intégralRésumé :
Integrated pest management (IPM) is an approach to pest control which emphasizes the Integration of biological, cultural, and chemical control methods for optimal pest management. The purpose of this thesis is to empirically examine the level and distribution of net economic benefits of Extension IPM, and to assess the relative importance of socioeconomic factors in affecting the adoption of IPM in the states of Indiana, Virginia, Georgia, New York, North Carolina, Texas, Massachusetts, Mississippi and the Northwest region.
Budgeting and hypothesis testing procedures are used to conduct a net returns analysis. Consumer-producer surplus analysis is used to assess IPM benefits to producers and consumers. Finally, a polychotomous logit model is used to assess the importance of socioeconomic factors affecting IPM adoption.
The results of these analyses show significantly higher returns and less variability of returns per acre for users of IPM as compared to non-users. Moreover, consumers receive significant positive economic gains. However, pesticide cost and the variance of pesticide cost per acre increase with increasing levels of IPM use in several states but decrease in a few others. Gross farm income, percent family income from farming, frequency of contacts with Extension agents, and the education level of respondents are the most important factors related to adoption of IPM. A typical user of IPM is white, male, with at least some college education, has frequent contacts with Extension agents, has a relatively large farm, higher gross farm income, and a higher percent family income from farming.Master of Science

Roth, Richard A. « Sustainable development : political/ideological aspects and implications for planning ». Diss., Virginia Tech, 1993. http://hdl.handle.net/10919/39119.
Texte intégralRésumé :
Recent evidence of widespread environmental degradation and global changes resulting from human activities have revived a debate about the sustainability of the progress of human welfare that began at least 200 years ago. In this renewed debate, the seriousness and causes of environmental degradation are subject to widely divergent interpretations. There are many conceivable sustainable futures; the most important differences among them are not technical but political and ideological.
The practice of environmental planning is concerned with a wide variety of contexts and situations at the human-environment interface. Because land use is at the root of many of the problems of environmental degradation (e.g., habitat destruction, air pollution, water pollution), land use planning is an appropriate focus for consideration of the role of environmental planning in sustainable development.
Planning as a profession, with its inherent future orientation and focus on public values, is well situated to deal with the kinds of problems raised in the discourse regarding sustainability. Examination of mainstream land use planning practices, however, reveals a reactive, reformist incrementalism that responds to environmental degradation caused by growth, but that addresses neither its causes nor its dynamics. Mainstream land use planning approaches have attempted to resolve conflicts between development and environment through spatial solutions at various scales. The need to plan for ecological sustainability is difficult to reconcile with the democratic ideal of local self-determination.
Many alternative approaches to land use planning for sustainable development focus on design solutions. The requirements of sustainability are not merely technical, however. There are both emancipatory possibilities and their opposite in sustainability. Implementing sustainability offers planners a number of choices.
They can act as mediators, demystifyers of technical information, exposers of hidden ideological assumptions, and advocates. They can strengthen existing authority, or work towards an enlightened self-determination at the local level.Ph. D.

Yok, Larry Tom. « The philanthropic priorities of Chinese and Japanese Americans as they relate to Asian American culturally specific museums ». Thesis, Nelson Mandela Metropolitan University, 2016. http://hdl.handle.net/10948/13160.
Texte intégralRésumé :
Asian American culturally specific museums began forming in the United States in 1963. There are now 11 in existence. Four of these museums (two Chinese American, one Japanese American and one Pan Asian American) dramatically expanded their programs and constructed large new facilities. These culturally specific museums are private nonprofit organizations that are reliant on private donors for most of their financial support. Asian Americans comprise the majority of these Asian American museums’ donor bases. Understanding why donors support these museums may be useful to the museums’ abilities to raise funds.In this thesis I explore the reasons Chinese and Japanese Americans support these culturally specific museums. I used data from my qualitative study involving in-depth interviews of 16 Chinese and Japanese American current and former donors to a Pan Asian culturally specific museum in Seattle, Washington along with interviews of chief executives and other key informants of five other culturally specific museums in addition to primary documents provided by the museums and related secondary information available through the Internet. I also conducted a literature review in the fields of Development Studies, racial and ethnic identity, museology, and philanthropy. While identifying the reasons donors support these culturally specific museums, I also identify the philanthropic priorities and criteria of Chinese and Japanese Americans residing in Seattle and compare them with similar studies of Asian American philanthropy conducted in other cities in the 1990’s. I also examine the roles played by these culturally specific museums in the promotion of social capital, cultural capital and heritage capital in their communities. Chinese and Japanese Americans support these museums to preserve and educate their communities about the contributions their forebears made to the development of the United States. Asian American history has been marginalized in conventional narratives and one mission of the Asian American culturally specific museums is to bring their stories into the American history mainstream. Creating and operating these museums requires substantial networking within the Chinese and Japanese American communities and with other ethnic communities to bring in visitors and obtain financial and other support. The museums promote social capital development through collaboration in the museums’ operations. They increase the communities’ cultural capital by assembling the dispersed cultural and heritage capital of the Chinese and Japanese American communities into curated collections. These Asian American culturally specific museums face challenges stemming from attrition in their donor bases due to age. The museums need to develop activities that attract new supporters who may be mixed race or mixed ethnicity or who are interested in social activism that impacts society. The museums also must create programs that are relevant to younger generations. The findings of this study lay the groundwork for further inquiry into the ways culturally specific museums promote bonding and bridging capital in low and middle class Asian American communities and the degree to which they affect development in their neighbourhoods. Further research into the museums’ educational programs efficacy as they relate to correcting misperceptions about Asian Americans among non-Asian Americans may be desirable.

The dissertation consists of three essays: 1) Productivity growth in the transportation industries in the United States: An application of the DEA Malmquist productivity index; 2) how does a carbon dioxide emissions change affect transportation productivity? A case study of the U.S. transportation sector from 2002 to 2011; and 3) forecast of CO2 emissions from the U.S. transportation sector: Estimation from a double exponential smoothing model. The first essay reviews productivity growth in the five major transportation industries in the United States (airline, truck, rail, pipeline, and water) and the pooled transportation industry from 2004 to 2011. The major findings are that the U.S. transportation industry shows strong and positive productivity growth except in the years of the global financial crisis in 2007, 2008, and 2010, and among the five transportation industries, the rail and water sectors show the highest productivity growth in 2011. The second essay examines the effects of a carbon dioxide (CO2) emissions change on actual productivity in the U.S. transportation sector. This study finds that a CO2 emissions increase from 2002 to 2007 had a negative effect on actual productivity in the U.S. transportation sector, but the CO2 emissions reduction for 2008?2011 increases actual productivity. States mainly showing sustainable growth patterns (decrease in CO2 emissions concurrent with increasing actual productivity) experience higher technological innovation increase than an efficiency decrease. This finding suggests that fuel-efficient and carbon reduction technologies as well as alternative transportation energy sources may be essential factors to both grow transportation and slow global warming. The third essay reviews whether the decreasing trend in U.S. CO2 emissions from the transportation sector since the end of the 2000s is consistent across all states in the nation for 2012?2021. A double exponential smoothing model is used to forecast CO2 emissions for the transportation sector in the 50 states and the U.S., and its findings are supported by pseudo out-of-sample forecasts validity testing. This study concludes that the decreasing trend in transportation CO2 emissions in the U.S. will continue in most states in the future.Mountain Plains Consortium (MPC)

Texte intégralRésumé :
AbstractThis chapter addresses social enterprises as a special corporate category, which in some European jurisdictions, and increasingly so after their promotion by the European Union, are provided with a specific legal framework to promote and encourage their development. The paper begins with a brief compilation of the several social enterprise concepts developed by economic doctrines both in the United States and Europe, which reveal a great diversity of approaches. This is followed by an analysis of the various documents published by the European Union, showing the increasing recognition of this business phenomenon, from the publication of the Social Business Initiative in 2011 to the recent Action Plan for the Social Economy in 2021. Finally, the results obtained from the analysis of the different European legal systems are presented, and three main models of legal regulation of social enterprises are distinguished, namely, the use of the social cooperative form, enactment of a special law, and integration into a social economy law.

Texte intégralRésumé :
This chapter elaborates on the culture of anonymity empowerment engrained within US history. It starts with Junius' letters, which became a prominent example of pseudonyms and anonymous speech that proliferated in England and the American colonies. Junius' letters feature potential legal, safety, economic, privacy, speech, and power motivations for seeking anonymity. The chapter also covers the Common Sense pamphlet making a call for colonial independence from England. The anonymous political speech did not halt when colonies achieved independence as Federalists like Alexander Hamilton, James Madison, and John Jay published articles to rebut Anti-Federalist criticisms and address aspects of the Constitution.

Texte intégralRésumé :
These five stories tell how poor relief shaped Americans’ lives in the early United States. Although the five subjects were unique individuals, living in the local contexts of Rhode Island towns, their stories teach much about welfare around the country at the time. This is because nearly every American state inherited colonial laws based on the Elizabethan Poor Law of England. How Welfare Worked in the Early United States focuses on several aspects of how these laws were implemented. Some aspects are rarely discussed in other histories: the difficulty of financing this safety net, the prominence of healthcare in poor relief, the use of paupers as temporary workers, and the isolation of poorhouse inmates. Other aspects, described well in other histories, are carefully illustrated in these narrative-style biographies: the benevolent effects of poor relief, the economic stimulus of poor relief spending, and the racialized application of the poor laws.

Texte intégralRésumé :
The United States` Critical Infrastructure System (CIs) represents an umbrella concept grouping all those resources that are essential for national economic, financial, and social system. These critical infrastructures are vital and without them, or with any damages to them, would cripple the nation, states, and/or local communities and tribes. Based on a systematic review approach (methodology), this paper aims to review the United States’ Critical Infrastructure Protection System (USCIPS) at tree aspects. In section one, the policy pillars of USCIPS are outlined based on studding Presidential Policy Directive 21 (PPD-21) and National Infrastructure Protection Plan (NIPP). Section two discusses the interdependent nature of the sixteen critical infrastructure sectors and identified the further designation of life-line sectors. Final sector introduces USCIPS stakeholders, collaboration and partnership across between the private sector and public sector stakeholders.

Texte intégralRésumé :
Mathematical competence is one of the eight basic key competencies which are defined by EU Directives. Mathematical competence includes the skills of applying basic processes and principles of mathematics in everyday contexts. The aim of current research is to identify the role of adult mathematics education and mathematical competence in sustainable development in case of Baltic States. We are continuing the investigations that began in the Nordplus research project “Cooperation to strengthen the citizens' math skills in the context of sustainable development and welfare”. The main objective of the research is to highlight the role of mathematics in a lifelong context. We separate two aspects of mathematics role in sustainable development. The first considers mathematics as a tool in processional work, the second considers the role of mathematical competence in the development of person's intelligence and personality. Both aspects are widely discussed in the scientific literature and in the programmatic documents of United Nations, United Nations Educational Scientific and Cultural Organizationn, Organisation for Economic Cooperation and Development. Through combining insights of theoretical goals of leading international institutions and actual survey data we can show the value of mathematical competence in adults in the Baltic states.

Texte intégralRésumé :
A detailed methodology was used to select the sea states tested in the final stage of the Wave Energy Prize (WEPrize), a public prize challenge sponsored by the U.S. Department of Energy [1]. The winner was selected based on two metrics: a threshold value expressing the benefit to effort ratio (ACE metric) and a second metric which included hydrodynamic performance-related quantities (HPQ). HPQ required additional sea states to query aspects of the techno-economic performance not addressed by ACE. Due to the nature of the WEPrize, limited time was allotted to each contestant for testing and thus a limitation on the total sea states was required. However, the applicability of these sea states was required to encompass seven deployment locations representative of the United States West Coast and Hawaii. A cluster analysis was applied to scatter diagrams in order to determine a subset of sea states that could be scaled to find the average annual power flux at each wave climate for the ACE metric. Four additional sea states were selected, including two highly energetic sea states and two bimodal sea states, to evaluate HPQ. These sea states offer a common experimental testing platform for performance in United States deployment climates.

Texte intégralRésumé :
Abstract Idaho was the 3rd largest milk producer in the United States in 2019, and the dairy industry remains one of the most considerable sections of the state’s economy. The dairy industry itself has many effects on the environment, and there are many opportunities within this industry to improve its environmental impacts. This paper explores a dairy processing facility (under current operating norms and an improved set of operating conditions) to assess techno-economic aspects, determine the gate-to-gate environmental impacts, and identify critical process parameters. In this study, the environmental impact was determined using the life cycle assessment method to evaluate greenhouse gas emissions in kg CO2 equivalents per kg of packaged milk. The economic assessment was performed, using a life cycle costing analysis method for estimating the net present value, payback period, and total profit of the various scenarios, as well as determining the major cost drivers to the process. The results show that the total environmental impact of 1 kg of packaged milk was between 0.0102 to 0.0125 kg CO2 equivalents. It was also determined that the proposed adjustments to the operating conditions could reduce the heating costs by 84% and the overall annual costs by 16.3%. This study can help provide justification for further research when determining the optimum operating conditions and energy sources for dairy processing equipment and facilities. This includes investigating both real-world and theoretical models when making plans for improving dairy processes.

Texte intégralRésumé :
Offshore wind power is an emerging technology capable of providing coastal cities, states, and countries with a substantial portion of their energy needs. The vast potential of offshore wind power has not been fully explored. This work endeavors to perform a review of the literature on offshore wind power. Structural, economic, and environmental aspects are discussed keeping in mind the current status of offshore wind power development around the world. Offshore wind power is a relatively new technology being used by countries such as Denmark, the United Kingdom, the United States, Germany, and China to provide larger and larger portions of their total energy needs. In 1991 Denmark opened its first commercial offshore wind farm in Vindeby producing a mere 4.95 MW of power. More ambitious projects followed and in 2001 the Middelgrunden, Copenhagen wind farm opened producing 40 MW of power. Then in 2000 the Horns Rev wind farm was put online producing 160 MW of power. The United Kingdom has many offshore wind power projects as well. The Blyth Offshore was opened in 2000 and produces 3.8 MW of power and several others in the United Kingdom produce anywhere from 10 to 90 MW of power. By 2007 end, Denmark had 402 MW and the UK had 395 MW, Ireland, Sweden and the Netherlands had varying amounts. Countries such as China and Germany are also leaders in the development of offshore wind power. In the United States, commercial offshore wind projects had a late start. The first operational offshore wind farms opened in 2007. However, the United States does not lag behind in wind power. In 2008 the United States produced more megawatt of wind power than any other country, making them the leader of wind power production. Offshore wind, however, only constitutes a tiny portion of the total wind power production of the United States. Recent advancements in the technology associated with wind power as a renewable energy source have made it a feasible form of climate change mitigation. Recent development has led countries such as Denmark, Portugal, and Spain to devote as much as 19% of their total energy production to wind power as of 2008, and is encouraging many other developed countries to do the same. This paper performs a review of the status of offshore wind projects internationally. It considers specifically the potential of the West Wind Drift near the southernmost tip of South America and the Antarctic Peninsula as a geographically and meteorologically advantageous location for the implementation of these wind technologies. Many of the more general problems associated with the use of wind turbines are eliminated by location alone. The winds that cause the Antarctic Circumpolar Currents (ACC) have a consistent west to east pattern and are some of the strongest winds on Earth, both ideal qualities when considering the possibility of wind power, and the wind in this area has very low intermittency. The average wind speed between 40°S and 60°S is 15 to 24 knots with strongest winds typically between 45°S and 55°S. Cape Horn is about 56°S [1]. Historically, the ACC has been called the ‘West Wind Drift’ because the prevailing westerly wind and current are both eastward. Owing to the remoteness of the Cape Horn area and Antarctica, many of the social matters associated with the development of wind farms are eliminated. Obvious factors must be considered when developing in such an area. The paper will cover the engineering requirements of turbines functioning in subzero temperatures consistently as well as the long distance transmission associated with development in this area and its economic feasibility. It will also cover the environmental and regulatory issues associated with the development in such an area.

Texte intégralRésumé :
Von Roll Inova is a major provider of thermal treatment technologies ranging from combustion, energy recovery, air pollution control, and residue processing. The company is headquartered in Switzerland and its portfolio includes over 300 WTEs around the world, processing more than 100,000 metric tons of solid wastes per day. This paper discusses the technological and political trends in Europe regarding waste-to-energy, the state-of-the-art-technology and presents an an overview of recently executed projects by Von Roll Inova. During the hiatus on new plant construction in the U.S., European countries pursued a variety of different approaches. Not all the results showed environmental, social or economic promise. Of the aspects developed since the mid-nineties, some are applicable to the United States. Particularly the advances in air pollution control technology and improved thermal efficiency will be useful as new Waste-to-Energy capacity is added in the U.S. and delays in permitting may be avoided by taking advantage of such experience transfers.

Texte intégralRésumé :
Liquefied Natural Gas (LNG) is an important component in meeting the future energy needs of the United States and other industrialized countries. The ability to locate (produce), process, liquefy, transport, and re-gasify stranded natural gas is vital to maintaining a stable long-term natural gas supply necessary for sustained economic growth [1]. Two of the key components in this supply chain are the vaporization of the LNG at the import terminal and the peak shaver trains that liquefy pipe line natural gas, store it and then vaporize the liquid to feed the gas to the pipe line when additional flow is required. This paper outlines a novel approach incorporating a traditional fired heater with waste heat recovery to vaporize LNG at an import terminal or peak shaver train while maintaining a high thermal efficiency. A comparison is made between the new technology and more conventional methods, with emphasis on emissions. Some of the advantages and disadvantages associated with the design and implementation of these systems are explored in this presentation. As a fundamental cannon of ethics, engineers are obligated to address the most efficient and responsible use of resources. The environmental impact of supplying the necessary natural gas energy to industry and consumers is significant. This paper addresses these aspects as considered during the development of the alternative LNG vaporization technology.

Texte intégralRésumé :
Cloud computing, as defined by United States National Institute of Standards and Technology (NIST), “... is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.” Goal of the study is to highlight the positive economical impacts of cloud computing for companies, which can be assessed by focusing on their business goals to make more profit. Under the cloud computing model, firms can rent as many virtual machines as they need at any given time, and either design or use off-the-shelf solutions to integrate company-wide data and then easily distribute access to users within and outside of the company. Hence, cloud computing converts fixed capital costs to variable costs, prevents under or over provisioning, and allows minute by minute flexibility. Hence, the companies concentrate on their own business goals on top on a stable and effective information technology backbone. Most literature on cloud computing reside in computer science resources. However, there is little work focusing on the social and economic significance of cloud computing in the economics literature. Hence, this paper first discusses the basics of the cloud computing along with its implications on information technology (IT) field, with paying special attention to economical aspects. Then, empirical results and elaborations are to be given to yield a conclusion.

Texte intégralRésumé :
When local governments evaluate the environmental benefits and costs of alternatives for managing non-recyclable municipal solid waste, the relative costs of modern waste-to-energy (WTE) technology can be a significant stumbling block despite WTE technology’s environmental benefits. Although the preceding point is an important economic reality that has constrained WTE development in the United States, fortunately there is a highly effective means — the use of municipal solid waste “flow control” (or “facility designation”) authority — to overcome WTE’s perceived cost disadvantage. The relationship between flow control and WTE development, including significant encouragement for use of flow control as a result of the U.S. Supreme Court’s recent decision in United Haulers Association v. Oneida-Herkimer Solid Waste Management Authority, 127 S.Ct. 1786 (2007), is the focus of this paper, which will address the following topics: Policy Basis for Flow Control — Absent government intervention, management of municipal solid waste will seek the lowest cost (i.e., short-term cost) and frequently less environmentally protective alternatives. Flow control can counter the tendency to choose alternatives with lower short-term costs and at the same time facilitate implementation of the environmentally-preferable waste management alternatives a local government selects, such as WTE technology and other aspects of “integrated waste management.” Flow Control and the Courts — While the authority of a given local government to use flow control is grounded in state law, flow control also implicates matters that arise under federal law, such as Commerce Clause issues, given the possibility that solid waste regulation in one state can affect commercial interests in solid waste management in another state. Although concerns regarding claims of impact on interstate commerce prompted a negative Supreme Court response to flow control in C&A Carbone, Inc. v. Town of Clarkstown, 511 U.S. 383 (1994), the Court’s decision 13 years later in the Oneida-Herkimer case was in many ways just the opposite. WTE’s Correlation with Flow Control and Practical Guideposts — WTE development can be significantly advanced by the use of flow control. That conclusion is borne out by empirical data. The concluding portion of this paper addresses that topic as well as corollary issues, such as public-private collaboration for WTE development and other practical guideposts for implementing flow control ordinances.

Texte intégralRésumé :
An estimated 623,000 individuals are living with a major lower leg amputation in the United States [1]. Of these amputations, 78% were due to peripheral vascular disease (PVD) and 45% were due to PVD in individuals with type I or II diabetes [2]. With diabetes and PVD incidence levels on the rise [1] and those in a depressed socio-economic situation more susceptible to develop type II diabetes [3], the demand for affordable, high quality ankle prostheses has never been higher. Prostheses currently available on the market include both passive and active devices, neither of which fully satisfies user requirements. Passive prostheses, the more commonly prescribed style, are economically priced but lack the powered push-off observed in a natural ankle [4] due to the absence of an actuator. As a result, passive prostheses cause a multitude of quality of life detriments to the end user including asymmetrical gait (for unilateral amputees), slower self-selected walking speeds, higher metabolic cost per distance traveled and increased pain in the residual limb [5–6]. Conversely, active devices can nearly match the functionality and powered push-off of a natural ankle [7] but are cost prohibitive. Among active devices, one of the most successful models is the BiOM. Initially developed at MIT, the BiOM uses an actuator in series with a spring to achieve near natural ankle behavior. In 2013, two years after the product’s official launch, the device cost approximately $50,000 and had only sold about 1,000 units [7]. The limitations of currently available ankle prostheses motivates work on a new solution, the EaSY-Walk (Early Stance Y-deflection), a passive ankle device that mimics several key aspects of a natural ankle joint, especially nonlinear rotational stiffness and rotational work output (powered push-off) that increases with walking velocity while remaining relatively inexpensive.

Texte intégralRésumé :
This document makes an assessment of the Political Dialogue and Cooperation Agreement (PDCA) between Cuba and the European Union (EU) in its four years of validity, and of the evolution of political and economic relations between both parties. The analysis is structured in five headings that address the background, determinants and significance of the PDCA between Cuba and the EU; the main elements discussed in the political dialogue —and in thematic dialogue— between the two parties since 2018, and the central aspects of trade, investment and cooperation relations between Cuba and the EU. The report concludes that, unlike the United States, the EU is able to support the complex process of economic and institutional transformations underway in Cuba, in four fundamental areas: i) technical assistance and advice for the design and implementation of public policies, macroeconomic management, decentralisation and local development; ii) cooperation to fight climate change and transform Cuba’s productive and technological structure; iii) the promotion and encouragement of foreign investment flows from Europe, targeting key productive sectors; and iv) the exploration of financial opportunities for Cuba through the European Investment Bank (EIB) under the current PDCA.

Kislev, Yoav, Ramon Lopez et Ayal Kimhi. Intergenerational Transfers by Farmers under Different Institutional Environments. United States Department of Agriculture, avril 1995. http://dx.doi.org/10.32747/1995.7604936.bard.
Texte intégralRésumé :
This research studies the issues of intergenerational transfers in general and farm succession in particular in two different institutional environments. One is the relatively unregulated farm sector in the United States, and the other is the heavily regulated family farms in Israeli moshavim. Most of the analysis is based on modern economic theory dealing with inheritance and other intergenerational issues. However, we start with two background studies. One is a review of the legal system affecting farm succession in the moshav, which, as we claim throughout the report, is of major importance to the question in hand. The second is an ethnographical study aimed at documenting various inheritance and succession practices in different moshavim. These two studies provide insight for most of the economic studies included here. The theoretical studies mostly deal with various aspects of two major decisions faced by farmers: who will succeed them on the farm, and when will succession take place. The first decision clearly depends on the institutional structure: for instance, Israeli farmers are limited to one successor while American farmers are not. The second decision can be taken in three stages: sharing farm work with the successor, sharing farm management, and eventually transferring the ownership. The occurrence and length of each stage depend on the first decision as well as on the institutional structure directly. The empirical studies are aimed at analyzing the practices and considerations of Israeli and American farmers regarding various intergenerational transfers-related issues. We found that American farmers' decisions are mainly driven by the desire to let the farm prosper in future generations and by a preference for equal treatment of heirs, and not at all by old-age support considerations. In contrast, we demonstrate the significant effect of old-age support on the value of the transferred farm in a sample of Israeli farms. Using Israeli census data, we find that the time of farm ownership transfer responds to economic incentives. A smaller Israeli panel data set shows that controlling for the occurrence of succession, farm size rises with operator's age and eventually falls, while intensity of production seems to decline steadily. This explains another finding, that farm transfer contributed significantly to farm growth when farming was attractive to successors. This finding supports our main conclusion, that the succession decisions are of major importance to the viability and profitability of family farms over the long run.

Kimhi, Ayal, Barry Goodwin, Ashok Mishra, Avner Ahituv et Yoav Kislev. The dynamics of off-farm employment, farm size, and farm structure. United States Department of Agriculture, septembre 2006. http://dx.doi.org/10.32747/2006.7695877.bard.
Texte intégralRésumé :
Objectives: (1) Preparing panel data sets for both the United States and Israel that contain a rich set of farm attributes, such as size, specialization, and output composition, and farmers’ characteristics such as off-farm employment status, education, and family composition. (2) Developing an empirical framework for the joint analysis of all the endogenous variables of interest in a dynamic setting. (3) Estimating simultaneous equations of the endogenous variables using the panel data sets from both countries. (4) Analyzing, using the empirical results, the possible effects of economic policies and institutional changes on the dynamics of the farm sector. An added objective is analyzing structural changes in farm sectors in additional countries. Background: Farm sectors in developed countries, including the U.S. and Israel, have experienced a sharp decline in their size and importance during the second half of the 20th century. The overall trend is towards fewer and larger farms that rely less on family labor. These structural changes have been a reaction to changes in technology, in government policies, and in market conditions: decreasing terms of trade, increasing alternative opportunities, and urbanization pressures. As these factors continue to change, so does the structure of the agricultural sector. Conclusions: We have shown that all major dimensions of structural changes in agriculture are closely interlinked. These include farm efficiency, farm scale, farm scope (diversification), and off-farm labor. We have also shown that these conclusions hold and perhaps even become stronger whenever dynamic aspects of structural adjustments are explicitly modeled using longitudinal data. While the results vary somewhat in the different applications, several common features are observed for both the U.S. and Israel. First, the trend towards the concentration of farm production in a smaller number of larger farm enterprises is likely to continue. Second, at the micro level, increased farm size is negatively associated with increased off-farm labor, with the causality going both ways. Third, the increase in farm size is mostly achieved by diversifying farm production into additional activities (crops or livestock). All these imply that the farm sector converges towards a bi-modal farm distribution, with some farms becoming commercial while the remaining farm households either exit farming altogether or continue producing but rely heavily on off-farm income. Implications: The primary scientific implication of this project is that one should not analyze a specific farm attribute in isolation. We have shown that controlling for the joint determination of the various farm and household attributes is crucial for obtaining meaningful empirical results. The policy implications are to some extent general but could be different in the two countries. The general implication is that farm policy is an important determinant of structural changes in the farm sector. For the U.S., we have shown the different effects of coupled and decoupled (direct) farm payments on the various farm attributes, and also shown that it is important to take into account the joint farm-household decisions in order to conduct a meaningful policy analysis. Only this kind of analysis explains the indirect effect of direct farm payments on farm production decisions. For Israel, we concluded that farm policy (or lack of farm policy) has contributed to the fast structural changes we observed over the last 25 years. The sharp change of direction in farm policy that started in the early 1980s has accelerated structural changes that could have been smoother otherwise. These accelerated structural changes most likely lead to welfare losses in rural areas.

Texte intégralRésumé :
Mycobacterium avium subsp. paratuberculosis (MAP) is the etiological agent of a severe inflammatory bowel disease (IBD) in ruminants, known as Johne’s disease or paratuberculosis. Johne’s disease is considered to be one of the most serious diseases affecting dairy cattle both in Israel and worldwide. Heavy economic losses are incurred by dairy farmers due to the severe effect of subclinical infection on milk production, fertility, lower disease resistance and early culling. Its influence in the United States alone is staggering, causing an estimated loss of $1.5 billion to the agriculture industry every year. Isolation of MAP from intestinal tissue and blood of Crohn's patients has lead to concern that it plays a potential pathogenic role in promoting human IDB including Crohn’s disease. There is great concern following the identification of the organism in animal products and shedding of the organism to the environment by subclinically infected animals. Little is known about the molecular basis for MAP virulence. The goal of the original proposed research was to identify MAP genes that are required for the critical stage of initial infection and colonization of ruminants’ intestine by MAP. We proposed to develop and use signature tag mutagenesis (STM) screen to find MAP genes that are specifically required for survival in ruminants upon experimental infection. This research projected was approved as one-year feasibility study to prove the ability of the research team to establish the animal model for mutant screening and alternative in-vitro cell systems. In Israel, neonatal goat kids were repeatedly inoculated with either one of the following organisms; MAP K-10 strain and three transposon mutants of K-10 which were produced and screened by the US PI. Six months after the commencement of inoculation we have necropsied the goats and taken multiple tissue samples from the jejunum, ileum and mesenteric lymph nodes. Both PCR and histopathology analysis indicated on efficient MAP colonization of all the inoculated animals. We have established several systems in the Israeli PI’s laboratory; these include using IS900 PCR for the identification of MAP and using HSP65-based PCR for the differentiation between MAV and MAP. We used Southern blot analysis for the differentiation among transposon mutants of K-10. In addition the Israeli PI has set up a panel of in-vitro screening systems for MAP mutants. These include assays to test adhesion, phagocytosis and survival of MAP to/within macrophages, assays that determine the rate of MAPinduced apoptosis of macrophages and MAP-induced NO production by macrophages, and assays testing the interference with T cell ã Interferon production and T cell proliferation by MAP infected macrophages (macrophage studies were done in BoMac and RAW cell lines, mouse peritoneal macrophages and bovine peripheral blood monocytes derived macrophages, respectively). All partners involved in this project feel that we are currently on track with this novel, highly challenging and ambitious research project. We have managed to establish the above described research systems that will clearly enable us to achieve the original proposed scientific objectives. We have proven ourselves as excellent collaborative groups with very high levels of complementary expertise. The Israeli groups were very fortunate to work with the US group and in a very short time period to master numerous techniques in the field of Mycobacterium research. The Israeli group has proven its ability to run this complicated animal model. This research, if continued, may elucidate new and basic aspects related to the pathogenesis MAP. In addition the work may identify new targets for vaccine and drug development. Considering the possibility that MAP might be a cause of human Crohn’s disease, better understanding of virulence mechanisms of this organism might also be of public health interest as well.
