The global potential for wind power generation is vast, and the number of installations is increasing rapidly. We review case studies from around the world of the effects on raptors of wind-energy development. Collision mortality, displacement, and habitat loss have the potential to cause population-level effects, especially for species that are rare or endangered. The impact on raptors has much to do with their behavior, so careful siting of wind-energy developments to avoid areas suited to raptor breeding, foraging, or migration would reduce these effects. At established wind farms that already conflict with raptors, reduction of fatalities may be feasible by curtailment of turbines as raptors approach, and offset through mitigation of other human causes of mortality such as electrocution and poisoning, provided the relative effects can be quantified. Measurement of raptor mortality at wind farms is the subject of intense effort and study, especially where mitigation is required by law, with novel statistical approaches recently made available to improve the notoriously difficult-to-estimate mortality rates of rare and hard-to-detect species. Global standards for wind farm placement, monitoring, and effects mitigation would be a valuable contribution to raptor conservation worldwide.

The economic case for low-carbon development in rapidly growing developing world cities: A case study of Palembang, Indonesia

Where costs or risks are higher, evidence is lacking or supporting institutions are less developed, policymakers can struggle to make the case for low-carbon investment. This is especially the case in developing world cities where decision-makers struggle to keep up with the pace and scale of change. Focusing on Palembang in Indonesia, this paper considers the economic case for proactive investment in low-carbon development. We find that a rapidly growing industrial city in a developing country can reduce emissions by 24.1% in 2025, relative to business as usual levels, with investments of USD405.6 million that would reduce energy expenditure in the city by USD436.8 million. Emissions from the regional grid could be reduced by 12.2% in 2025, relative to business as usual trends, with investments of USD2.9 billion that would generate annual savings of USD175 million. These estimates understate the savings from reduced expenditure on energy subsidies and energy infrastructure. The compelling economic case for mainstreaming climate mitigation in this developing country city suggests that the constraints on climate action can be political and institutional rather than economic. There is therefore a need for more effective energy governance to drive the transition to a low-carbon economy. - Highlights: • We evaluate the economic case for low carbon investment in a developing world city. • Cost-effective measures could reduce emissions by 24.1% relative to BAU levels. • These pay for themselves in <1 year and generate savings throughout their lifetime. • Further savings come from reduced expenditure on energy infrastructure, subsidies. • Limitations on climate action seem to be political/institutional – not economic

The aim of this study was to examine the effect of playing the online game World of Warcraft (WoW), both on adolescent's (effective) social interaction and on the competence they developed on it. Social interactions within the game environment have been investigated by integrating qualitative and quantitative methods: conversation analysis and social network analysis (SNA). From a psychosocial point of view, the in-game interactions, and in particular conversational exchanges, turn out to be a collaborative path of the joint definition of identities and social ties, with reflection on in-game processes and out-game relationship.

World Biofuels Study

Energy Technology Data Exchange (ETDEWEB)

Alfstad,T.

2008-10-01

rapidly over the next two decades, provided policymakers stay the course with their policy goals. This project relied on a scenario-based analysis to study global biofuel markets. Scenarios were designed to evaluate the impact of different policy proposals and market conditions. World biofuel supply for selected scenarios is shown in Figure 1. The reference case total biofuel production increases from 12 billion gallons of ethanol equivalent in 2005 to 54 billion gallons in 2020 and 83 billion gallons in 2030. The scenarios analyzed show volumes ranging from 46 to 64 billion gallons in 2020, and from about 72 to about 100 billion gallons in 2030. The highest production worldwide occurs in the scenario with high feedstock availability combined with high oil prices and more rapid improvements in cellulosic biofuel conversion technologies. The lowest global production is found in the scenario with low feedstock availability, low oil prices and slower technology progress.

An Analysis of Open World PvP in LOTRO's PvMP as a Case Study for PvP Games

Directory of Open Access Journals (Sweden)

Toh Weimin

2014-11-01

Full Text Available This article focuses on the analysis of emergent gameplay, based on a case study of the author's subjective gameplay experience of Player versus Monster Player (PvMP in The Lord of the Rings Online (LOTRO. The argument presented here is that although there is a core system of Player versus Player (PvP which LOTRO shares with other online games, each type of online game has a specific kind of PvP system which attracts players to engage in the gameplay. For instance, the open world sandbox type of PvP attracts certain players to play in LOTRO's PvMP. One of the main aims of this study is thus to investigate some of the core systems of PvP gameplay in open world sandbox PvP. In this article, LOTRO is shown to offer unique opportunities for studying emergent gameplay in open world games, with particular relevance to PvP studies. Two of the core systems of PvP discussed include the design of the simple gameplay rules to support emergent gameplay, and the community's attitudes towards player's behaviours. The types of emergent gameplay discussed include free play versus negotiated fair play, the players' utilisation of strategies in open world PvP to support collaborative and competitive gameplay, and the changing dynamics of open ended gameplay. It is hoped that the analysis provided in this article would form the­ basis of future work on a more general framework for understanding PvP in other online games.

Climate change adaptation under uncertainty in the developing world: A case study of sea level rise in Kiribati

Science.gov (United States)

Donner, S. D.; Webber, S.

2011-12-01

Climate change is expected to have the greatest impact in parts of the developing world. At the 2010 meeting of U.N. Framework Convention on Climate Change in Cancun, industrialized countries agreed in principle to provide US$100 billion per year by 2020 to assist the developing world respond to climate change. This "Green Climate Fund" is a critical step towards addressing the challenge of climate change. However, the policy and discourse on supporting adaptation in the developing world remains highly idealized. For example, the efficacy of "no regrets" adaptation efforts or "mainstreaming" adaptation into decision-making are rarely evaluated in the real world. In this presentation, I will discuss the gap between adaptation theory and practice using a multi-year case study of the cultural, social and scientific obstacles to adapting to sea level rise in the Pacific atoll nation of Kiribati. Our field research reveals how scientific and institutional uncertainty can limit international efforts to fund adaptation and lead to spiraling costs. Scientific uncertainty about hyper-local impacts of sea level rise, though irreducible, can at times limit decision-making about adaptation measures, contrary to the notion that "good" decision-making practices can incorporate scientific uncertainty. Efforts to improve institutional capacity must be done carefully, or they risk inadvertently slowing the implementation of adaptation measures and increasing the likelihood of "mal"-adaptation.

WTO confidential: the case of asbestos. World Trade Organization.

Science.gov (United States)

Castleman, Barry

2002-01-01

The World Trade Organization (WTO), created in 1995, adjudicates "trade disputes" between member nations in cases with great human rights, cultural, environmental, and public health significance. Throughout the process of dispute resolution and even after a case is concluded, very little of what happens is made accessible to the public. However, it is one thing to criticize the WTO for its lack of transparency from outside the process, and another to critically examine what was withheld from disclosure and what dangers that presents. This is the inside story from a scientific adviser to one of the parties in a WTO case, analyzing what happened from a public health point of view. This analysis concludes that the public health justification of banning asbestos was accepted in the end by the economists at the WTO, despite the WTO's bias in favoring the party (Canada) making the free trade challenge (to public health legislation, in this case) in numerous stages of the process, despite the WTO's utter lack of expertise in science, medicine, engineering, and public health, and despite important erroneous statements made to the WTO under the cover of confidentiality. Despite its result, this case illustrates that the WTO's threat to national sovereignty could never withstand the light of day, that the people of the world would reject this dangerous free trade fundamentalism if the limitations and dangers of the process were open for all to see.

Stakeholder collaboration in a prospective World Heritage Area: The case of Kokoda and the Owen Stanley Ranges

Directory of Open Access Journals (Sweden)

Amy Louise Bott

2011-05-01

Full Text Available The process of listing a World Heritage Area (WHAc in developing countries is often much more complex than in the West. Often all stakeholders are not taken into consideration and there is a lack of understanding of the concept of World Heritage and what it entails. This is particularly true for stakeholders who live in or adjacent to the proposed WHA, such as local communities. This paper presents a case study of Kokoda and the Owen Stanley Ranges, currently a tentative World Heritage site, to show the complexities in stakeholder collaboration and attribution in the process of World Heritage designation. Six key stakeholders were identified in the study. Upon examination of four attributes of stakeholders: power; legitimacy; urgency; and proximity, it was found that all stakeholders in this case study have a high legitimacy in the listing process however only the local community holds high levels of power, urgency and proximity. Additionally it was found that several stakeholders, like the private sector, have too many weak relationships with other stakeholders, resulting in a lack of communication. These findings present the first step in understanding how it might be possible to improve the listing process of World Heritage Sites in developing countries through effective stakeholder collaboration.

Full Text Available In summer, 2010, gambling cases of sumo wrestlers and bosses and the connection with the gangsters were reported day after day through mass media. This article chases the summary of a chain of these cases and the correspondence of the Sumo Association for it. The article looks at the present conditions of a unique competition called sumo from these a series of cases. At first, it examines the summary of the illegal gambling case of Ozeki Kotomitsuki, the top of Japanese sumo wrestlers, and the correspondence of Sumo Association and other social organs. It takes up a problem about holding the tournament at Nagoya this summer next. And it relates to dark customs of sumo world that a series of cases are able to happen and tries to explain such customs through the tradition of sumo. While writing this article, the news to ask the self-purification capacity of the Association and to suggest relations with the sumo world and the gangsters are reported every day. The darkness of the sumo world seems to be wide and deep.This article is in Japanese. In summer 2010, a scandal in gambling on baseball matches implicating sumo wrestlers and their bosses was reported day after day by Japanese mass media. This scandal revealed the connections between the sumo world and criminal organizations and lead to unprecedented actions, such as the dismissal of the active Ozeki Kotomitsuki, one of the top Japanese sumo wrestlers, and the suspension of live television broadcasting of the sumo tournament. The reason why the Japanese public instigated mass public debates may relate to the notion that sumo has an intimate association with the gods, reinforced with its special position in Japanese tradition and culture. This article first presents a brief history of sumo and explains its particular characteristics. Then it provides a summary of the chain of events in the baseball gambling scandal and the responses from the Japan Sumo Association. In conjunction with

Kozikowski, Tania A; Magdesian, K Gary; Puschner, Birgit

2009-08-01

To characterize the clinical and clinicopathologic effects and evaluate outcome associated with oleander toxicosis in New World camelids. Retrospective case series. 11 llamas and 1 alpaca. Medical records from a veterinary medical teaching hospital from January 1, 1995, to December 31, 2006, were reviewed. Records of all New World camelids that had detectable amounts of oleandrin in samples of serum, urine, or gastrointestinal fluid were included in the study. Descriptive statistics were used to evaluate the history, physical examination findings, clinicopathologic data, and outcome of affected camelids. 11 llamas and 1 alpaca met the inclusion criteria of the study. Either oleander plants were present where the camelids resided (n = 7) or oleander plant material was identified in the hay fed to the camelids (5). One llama was dead on arrival at the hospital, and another was euthanized upon admission because of financial concerns. Of the 10 treated camelids, 9 had evidence of acute renal failure, 7 had gastrointestinal signs, and 4 had cardiac dysrhythmias on initial evaluation. The overall mortality rate was 25%, but the mortality rate for the 10 camelids that were medically treated was 10%. In New World camelids, oleander intoxication was associated with a triad of clinical effects (ie, renal, gastrointestinal, and cardiovascular dysfunction). Oleander intoxication often represented a herd problem but carried a fair to good prognosis if treated promptly. Oleander toxicosis should be considered a differential diagnosis in sick camelids.

Many have previously reviewed empirical findings and theoretical developments from this work. Here we instead provide a brief perspective on approaches, considerations, and challenges to studying real-world perceptual expertise. We discuss factors like choosing to use real-world versus artificial object domains of expertise, selecting a target domain of real-world perceptual expertise, recruiting experts, evaluating their level of expertise, and experimentally testing experts in the lab and online. Throughout our perspective, we highlight expert birding (also called birdwatching as an example, as it has been used as a target domain for over two decades in the perceptual expertise literature.

Art, Science and History in a Globalized World: the Case of Italy-China

Directory of Open Access Journals (Sweden)

Salvatore Lorusso

2015-12-01

Full Text Available Art and science, over the centuries, though starting from different positions, have very often led to the same conclusions. History, on the other hand, establishes identities that derive from our past and allows for exchanges and unity between people of different nationalities, in both a commercial and scientific context, in a world without borders, in spite of obvious contradictions related to this globalized world. The case of Italy-China bears witness to this in a significant way.A case in point is represented by the scientific collaboration between the Alma Mater University of Bologna and Zhejiang University, as well as that between the Salesian Pontifical University of Rome and Fudan University in Shanghai, Zhejiang University and the Foreign Studies University of Beijing.In the first case, the ongoing research project “Historical anamnesis, preservation and valorization of the statues of the Longxing Buddhist Temple of Qingzhou (China” is being carried out between the Department of Cultural Heritage Diagnostic Laboratory for Cultural Heritage of the University of Bologna and the Cultural Heritage Institute of Zhejiang University. In the second case, collaboration between the Salesian Pontifical University and the Chinese Universities, covers activities relating to the study of philosophy, pedagogy and Latin language and literature.The paper highlights the importance of drawing value of a cultural, conservative, social, identitary nature within the context of the holistic value of cultural heritage and respecting ethical aspects at a personal and interpersonal level, in particular, by offering young people the opportunity to enter the employment market and of which they are currently experiencing all the problematic fluctuations.

Humanitarian logistics: Review and case study of Zimbabwean experiences

Directory of Open Access Journals (Sweden)

Charles Mbohwa

2010-11-01

Full Text Available This paper reviews and presents findings on mini-case studies done on the difficulties and problems faced by humanitarian organisations in running logistics systems in Zimbabwe. Document analysis was done and this was complemented by mini-case studies and semi-structured interviews and site visits. Mini-case studies of the operations of the World Food Programme, the International Red Cross Society and the Zimbabwe Red Cross Society, the World Health Organisation, the United Nations Children's Fund and the Zimbabwean Civil Protection Organisation in Zimbabwe are discussed. These clarify the difficulties and problems faced such as the lack of trained logistics personnel, lack of access to specialised humanitarian logistics courses and research information, the difficulty in using and adapting existing logistics systems in attending to humanitarian logistics and the lack of collaborative efforts that address the area specifically. This study seeks to use primary and secondary information to inform decision-making in humanitarian logistics with possible lessons for neighbouring countries, other regions in Africa and beyond. Activities on collaborative networks that are beneficial to humanitarian logistics are also suggested.

Objectives Healthcare leaders around the world are calling for radical, transformational change of our health and care systems. This will be a difficult and complex task. In this article, we examine case studies in which transformational change has been achieved, and seek to learn from these experiences. Methods We used the case study method to investigate examples of transformational change in healthcare. The case studies were identified from preliminary doctoral research into the transition towards future sustainable health and social care systems. Evidence was collected from multiple sources, key features of each case study were displayed in a matrix and thematic analysis was conducted. The results are presented in narrative form. Results Four case studies were selected: two from the US, one from Australia and one from the UK. The notable features are discussed for each case study. There were many common factors: a well communicated vision, innovative redesign, extensive consultation and engagement with staff and patients, performance management, automated information management and high-quality leadership. Conclusions Although there were some notable differences between the case studies, overall the characteristics of success were similar and collectively provide a blueprint for transformational change in healthcare. What is known about the topic? Healthcare leaders around the world are calling for radical redesign of our systems in order to meet the challenges of modern society. What does this paper add? There are some remarkable examples of transformational change in healthcare. The key factors in success are similar across the case studies. What are the implications for practitioners? Collectively, these key factors can guide future attempts at transformational change in healthcare.

To provide examples of a qualitative multiple case study to illustrate the specific strategies that can be used to ensure the credibility, dependability, confirmability and transferability of a study. There is increasing recognition of the valuable contribution qualitative research can make to nursing knowledge. However, it is important that the research is conducted in a rigorous manner and that this is demonstrated in the final research report. A multiple case study that explored the role of the clinical skills laboratory in preparing students for the real world of practice. Multiple sources of evidence were collected: semi-structured interviews (n=58), non-participant observations at five sites and documentary sources. Strategies to ensure the rigour of this research were prolonged engagement and persistent observation, triangulation, peer debriefing, member checking, audit trail, reflexivity, and thick descriptions. Practical examples of how these strategies can be implemented are provided to guide researchers interested in conducting rigorous case study research. While the flexible nature of qualitative research should be embraced, strategies to ensure rigour must be in place.

The Good, the Bad and the Ugly: Using good and Cooperative Governance to improve Environmental Governance of South African World Heritage sites: A Case Study of the Vredefort Dome

Full Text Available South Africa became a signatory to and ratified the World Heritage Convention, 1972 (WHC in 1997. It thereby voluntarily agreed to identify and conserve world heritage areas of universal value for the benefit of mankind. This article presents a case study of the Vredefort Dome, one of South Africa's World Heritage Sites (WHS and specifically its governance strategies to ensure proper and sustainable governance. Firstly, the issue of fragmentation of the environmental governance regime applicable to WHS is discussed, and in doing so, refers to the various legislative and common law responsibilities and institutional structures related to environmental governance of WHS. Secondly, it briefly discusses the concept of good governance and the concept of cooperative governance as a sub-component of good governance. Finally it comprehensively proposes various strategies to ameliorate the current fragmented and unsustainable environmental governance effort relating to WHS.

Achieving attainable outcomes from good science in an untidy world: case studies in land and air pollution.

While scientific understanding of environmental issues develops through careful observation, experiment and modelling, the application of such advances in the day to day world is much less clean and tidy. Merseyside in northwest England has an industrial heritage from the earliest days of the industrial revolution. Indeed, the chemical industry was borne here. Land contamination issues are rife, as are problems with air quality. Through the examination of one case study for each topic, the practicalities of applied science are explored. An integrated, multidisciplinary response to pollution needs more than a scientific risk assessment. The needs of the various groups (from public to government) involved in the situations must be considered, as well as wider, relevant contexts (from history to European legislation), before a truly integrated response can be generated. However, no such situation exists in isolation and the introduction of environmental investigations and the exploration of suitable, integrated responses will alter the situation in unexpected ways, which must be considered carefully and incorporated in a rolling fashion to enable solutions to continue to be applicable and relevant to the problem being faced. This integrated approach has been tested over many years in Merseyside and found to be a robust approach to ever-changing problems that are well described by the management term, "wicked problems".

Barriers and opportunities in realising sustainable energy concepts--an analysis of two Swiss case studies

International Nuclear Information System (INIS)

Pohl, Christian; Gisler, Priska

2003-01-01

What assists and what hinders sustainable energy use in being put into effect? Two case studies of sustainable energy concepts--the Zurich Solarstromboerse, where electricity can be purchased that is produced by solar panels, and the Swiss CO 2 -law, a consensus oriented implementation of the Kyoto-protocol--were analysed in order to investigate this question. In both case studies the unfolding of the sustainable energy concepts is reconstructed as a process starting with an abstract idea moving to a concrete realisation. This process passes through a series of different social worlds and is, in turn, affected by them. These social worlds are e.g. those of the concerned scientists, the professional investors, energy suppliers or governmental agencies. The case studies reveal three neuralgic challenges that have to be met when a concept advances from idea to realisation through the social worlds: Firstly, the translation between social worlds changes the content of the idea. Secondly, the way each social world looks at things (socially) constructs best solutions to problems and hides others. Thirdly, the actual dynamics of the social world within which it is finally implemented must be adopted by the idea. In order to integrate these neuralgic points, scientists as well as other inventors have to retain responsibility for their sustainable energy ideas and are requested to follow them through the social worlds in order to critically survey and eventually influence their 'content in flux'

Communicating solutions for a greener world - a case study of the Bellona Foundation's communication process within the hydrogen project

International Nuclear Information System (INIS)

Loene, Cecilie

2001-01-01

The world is facing increasing energy and global climate change problems. Facing future depletion of fossil fuels and the threat of increased temperatures on earth due to air pollution from the burning of fossil fuels, there is a need for a clean alternative. The Norwegian environmental organization The Bellona Foundation believes that hydrogen as an energy carrier coupled with hydrogen technology is the solution and the only road to a 0-emissions society-a hydrogen society. Under the slogan, ''From Talking to Walking the Hy-way,'' Bellona is through their Hydrogen Project working to achieve this green society. In a case study of Bellona's Hydrogen Project, this thesis aims to examine how Bellona communicates with the intended target groups within this project and how the organization perceives the communication process. As the slogan suggests, in order for the Hydrogen Project to be completely successful, Bellona has to not only inform people about the hydrogen solution but also convince them and get them to begin implementing hydrogen technology. This is conducted through a communication process. The communication process includes both internal and external activities and is divided into four stages: translation, strategy, channels and feedback. Through contrasting the communication process with science communication models, the need for an interactive, multi-directional approach that makes problematic the receiver and recognizes the receiver as an active participant in addition to adhering to the correlation between message and context of the receiver. The case study aims to look at how Bellona conducts and perceives the different stages in the communication process and find out whether Bellona recognizes these features in or adheres to these factors within the Hydrogen Project.

Occupational therapy practitioners frequently identify opportunities for international practice. The World Health Organization and the World Federation of Occupational Therapists have encouraged occupational therapists to address transnational issues, social inclusion, and equal access to opportunities grounded in meaningful occupation (WFOT, 2012). This case study describes a partnership between two U.S. schools of occupational therapy and a Cuban community based pediatric clinic. It examines the dynamics that have sustained the partnership despite political, economic, and logistical barriers. The literature is scrutinized to show how this case study fits into other accounts of collaborative international partnerships. Particularly, it investigates structural and institutional conditions that shape international sustainable partnerships. In doing so, we answer the following questions: (1) Under which circumstances do international partnerships emerge and flourish? (2) What structural and institutional conditions shape international sustainable partnerships? And (3) How do partners perceive and experience the bilateral international partnership? It also discusses and illustrates the foundations and development of international partnerships that succeed. Through the use of a case study we illustrate the development of this partnership. Finally, we consider the next steps of this particular sustainable and collaborative international partnership. © 2015 John Wiley & Sons, Ltd.

Case-control studies are commonly used to evaluate effectiveness of licensed vaccines after deployment in public health programs. Such studies can provide policy-relevant data on vaccine performance under 'real world' conditions, contributing to the evidence base to support and sustain introduction of new vaccines. However, case-control studies do not measure the impact of vaccine introduction on disease at a population level, and are subject to bias and confounding, which may lead to inaccurate results that can misinform policy decisions. In 2012, a group of experts met to review recent experience with case-control studies evaluating the effectiveness of several vaccines; here we summarize the recommendations of that group regarding best practices for planning, design and enrollment of cases and controls. Rigorous planning and preparation should focus on understanding the study context including healthcare-seeking and vaccination practices. Case-control vaccine effectiveness studies are best carried out soon after vaccine introduction because high coverage creates strong potential for confounding. Endpoints specific to the vaccine target are preferable to non-specific clinical syndromes since the proportion of non-specific outcomes preventable through vaccination may vary over time and place, leading to potentially confusing results. Controls should be representative of the source population from which cases arise, and are generally recruited from the community or health facilities where cases are enrolled. Matching of controls to cases for potential confounding factors is commonly used, although should be reserved for a limited number of key variables believed to be linked to both vaccination and disease. Case-control vaccine effectiveness studies can provide information useful to guide policy decisions and vaccine development, however rigorous preparation and design is essential.

Papargyropoulou, Effie; Colenbrander, Sarah; Sudmant, Andrew Heshedahl; Gouldson, Andy; Tin, Lee Chew

2015-11-01

The provision of appropriate waste management is not only an indicator of development but also of broader sustainability. This is particularly relevant to expanding cities in developing countries faced with rising waste generation and associated environmental health problems. Despite these urgent issues, city authorities often lack the evidence required to make well-informed decisions. This study evaluates the carbon and economic performance of low-carbon measures in the waste sector at a city level, within the context of a developing country. Palembang in Indonesia is used as a case of a medium-sized city in a newly industrialized country, with relevance to other similar cities in the developing world. Evidence suggests that the waste sector can achieve substantial carbon emission reductions, and become a carbon sink, in a cost effective way. Hence there is an economic case for a low carbon development path for Palembang, and possibly for other cities in developing and developed countries facing similar challenges.

It provides a case study which illuminates the problems of extending occupational health services in developing economies and questions of public policy regarding utilization of medical resources and the priority that occupational health should hold in such a society. Occupational health has become a serious problem in the developing world as new industries and accelerating ecnomic development occur without adequate resources for worker protection. The study of cases such as that of Venezuela may provide guidance for anticipating and preventing problems in other nations. This paper should be considered a pilot study to explore a social aspect of occupational health that has not received adequate attention.

Davis, Mary E; Rappaport, Ann

2014-10-15

Data on air quality are remarkably limited in the poorest of the world's countries. This is especially true for post-conflict and disaster zones, where international relief efforts focus largely on more salient public health challenges such as water and sanitation, infectious diseases, and housing. Using post-earthquake Haiti as the example case, this commentary explores air quality challenges in the developing world, highlighting concerns related to infrastructure damage from post-conflict and disaster settings. We contend that there is a growing and presently unmet need for further research and attention from the global health community to address these issues. Copyright © 2014 Elsevier B.V.

Enhancing Systems Engineering Education Through Case Study Writing

Science.gov (United States)

Stevens, Jennifer Stenger

2016-01-01

Developing and refining methods for teaching systems engineering is part of Systems Engineering grand challenges and agenda for research in the SE research community. Retention of systems engineering knowledge is a growing concern in the United States as the baby boom generation continues to retire and the faster pace of technology development does not allow for younger generations to gain experiential knowledge through years of practice. Government agencies, including the National Aeronautics and Space Administration (NASA), develop their own curricula and SE leadership development programs to "grow their own" systems engineers. Marshall Space Flight Center (MSFC) conducts its own Center-focused Marshall Systems Engineering Leadership Development Program (MSELDP), a competitive program consisting of coursework, a guest lecture series, and a rotational assignment into an unfamiliar organization engaged in systems engineering. Independently, MSFC developed two courses to address knowledge retention and sharing concerns: Real World Marshall Mission Success course and its Case Study Writers Workshop and Writers Experience. Teaching case study writing and leading students through a hands-on experience at writing a case study on an SE topic can enhance SE training and has the potential to accelerate the transfer of experiential knowledge. This paper is an overview of the pilot experiences with teaching case study writing, its application in case study-based learning, and identifies potential areas of research and application for case study writing in systems engineering education.

The Problem of World Order in Western IR Studies

Maria Victorovna Soljanova

2016-01-01

Full Text Available The article "Problem of world order in modern Western studies" is the study of one of the most debated issues in the science of international relations - world order. Discussion of the structure of world order is underway in various countries, both at the state level and in the expert community. Some researchers insist on the fact that after the end of the cold war, the collapse of the bipolar model of international relations, the world has become unipolar. Others argue that the increase in the number of centers of power and the need for a multilateral approach to solving global problems (terrorism, proliferation of weapons of mass destruction, environmental and climate issues talking about the formation of multipolarity. However, it should be recognized that currently no widely accepted theoretical and conceptual apparatus, which complicates not only the study of the world order, but makes it impossible to search for common approaches of the international community in solving the problems associated with global development, new challenges and threats. The author of this article seeks to research and analyze the various theoretical paradigms (neo-realism, neo-liberalism, institutionalism, neo-marxism, etc. and concepts to form a coherent picture of the structure of the world system, its main features and to offer readers the vision of the concept of "world order". Thus, the article notes that the multidimensional structure of the modern system of international relations established after the end of the cold war is so complex that none of the concepts can claim to accurate interpretation of the world order. The modern system differs from systems of the past centuries. Characteristics inherent in it (on the one hand, the increasing global processes in economy, politics, culture, etc., on the other, the attraction to return to the concept of "nation state", the closure of borders, the disintegration, require new approaches to the study of world

The vast numbers of studies regarding caloric restriction (CR) and breast cancer risk are based on war-related extreme situations. Studying the impact of CR in Jews during World War II (WW II) is challenging due to its variance and duration. To develop novel research tools in order to assess CR exposure in Jews that occurred more than 60 years ago during WW II. A pilot study based on Israeli women born in Europe in 1926-45, who lived there during WWII. Primary incident breast cancer patients and population-based controls were interviewed using a detailed questionnaire referring to demographic, obstetric factors and WW II experiences. Exposure to WWII-related CR was assessed by several proxy variables based on this information. The individual hunger score was higher in the exposed cases [mean score 141.06 vs. 130.07 in the controls). The same trend was observed for self perceived hunger score (mean score 2.75 in cases vs. 2.40 in controls) and hunger symptoms score (4.89 vs. 3.56, respectively). The novel research tools are appropriate for comparative assessment of CR exposure in case control studies.

Paradoxes of ideological privilege – a case study

Directory of Open Access Journals (Sweden)

Kaja Kaźmierska

2014-01-01

Full Text Available The paper discusses a case study based on Lodz as an industrial city and a biography of a female textile worker who worked in one of textile factories in Lodz between 1975 -1998. In order to analyse the case I have also used other materials – works of historians and sociological research carried out by Hanna Świda-Ziemba in late 1940′s in Lodz. I place the analysed biography in both chronological and social context in order to reconstruct a complete image of Lodz and the world of female textile workers. Lodz, as the industrial city which had not been damaged during World War two became – from the point of view of authorities – the place where main assumptions of the new political deal could come true. Conversely the analyses of empirical data disclose the paradoxes of the system related to the asymmetry between the powerful ideological definition of workers as a leading class and the reality of their lives represented in analysed material.

These examinations are delivered in partnership with a commercial online testing company as part of the Industry Master’s degree at Charles Sturt University (CSU. The Industry Master’s degree is an academic program for students currently employed in the IT industry. Using Internet Based Testing (IBT, these students are examined in test centres throughout the world. This offers many benefits. For example, students have the freedom of sitting exams at any time during a designated interval. Computer-based testing also provides instructors with valuable feedback through test statistics and student comments. In this paper, we document CSU’s use of the IBT system, including how tests are built and delivered, and how both human and statistical feedback is used to evaluate and enhance the testing process.

Shuttle Transportation System Case-Study Development

Science.gov (United States)

Ransom, Khadijah

2012-01-01

A case-study collection was developed for NASA's Space Shuttle Program. Using lessons learned and documented by NASA KSC engineers, analysts, and contractors, decades of information related to processing and launching the Space Shuttle was gathered into a single database. The goal was to provide educators with an alternative means to teach real-world engineering processes and to enhance critical thinking, decision making, and problem solving skills. Suggested formats were created to assist both external educators and internal NASA employees to develop and contribute their own case-study reports to share with other educators and students. Via group project, class discussion, or open-ended research format, students will be introduced to the unique decision making process related to Shuttle missions and development. Teaching notes, images, and related documents will be made accessible to the public for presentation of Space Shuttle reports. Lessons investigated included the engine cutoff (ECO) sensor anomaly which occurred during mission STS-114. Students will be presented with general mission infom1ation as well as an explanation of ECO sensors. The project will conclude with the design of a website that allows for distribution of information to the public as well as case-study report submissions from other educators online.

To compare the diagnostic accuracy of emergency department (ED) physicians with the World Health Organization (WHO) case definition in a large community-based SARS (severe acute respiratory syndrome) cohort. This was a cohort study of all patients from Hong Kong's Amoy Garden complex who presented to an ED SARS screening clinic during a 2-month outbreak. Clinical findings and WHO case definition criteria were recorded, along with ED diagnoses. Final diagnoses were established independently based on relevant diagnostic tests performed after the ED visit. Emergency physician diagnostic accuracy was compared with that of the WHO SARS case definition. Sensitivity, specificity, predictive values and likelihood ratios were calculated using standard formulae. During the study period, 818 patients presented with SARS-like symptoms, including 205 confirmed SARS, 35 undetermined SARS and 578 non-SARS. Sensitivity, specificity and accuracy were 91%, 96% and 94% for ED clinical diagnosis, versus 42%, 86% and 75% for the WHO case definition. Positive likelihood ratios (LR+) were 21.1 for physician judgement and 3.1 for the WHO criteria. Negative likelihood ratios (LR-) were 0.10 for physician judgement and 0.67 for the WHO criteria, indicating that clinician judgement was a much more powerful predictor than the WHO criteria. Physician clinical judgement was more accurate than the WHO case definition. Reliance on the WHO case definition as a SARS screening tool may lead to an unacceptable rate of misdiagnosis. The SARS case definition must be revised if it is to be used as a screening tool in emergency departments and primary care settings.

The research aimed to identify the interaction of nurses and clients suffering from bulimia and anorexia. We use the case study as a resource in which we collect clinical data and did interviews with eight of fourteen nurses, who have been our subject-object. According to the nurses, clients are isolated from the world living in a world without hunger and mirrors reflecting a body always above the "ideal weight", they were lonely people, personnel who have lost their shine, sending signals that could extinguish their lives at any time. In the study, was possible to identify the manner in which nurses interacted and perceived customers and, as a result, we elucidate a peculiar practice in nursing.

Searching in small-world networks

We study the average time it takes to find a desired node in the Watts-Strogatz family of networks. We consider the case when the look-up time can be neglected and when it is important, where the look-up time is the time needed to choose one among all the neighboring nodes of a node at each step in the search. We show that in both cases, the search time is minimum in the small-world regime, when an appropriate distance between the nodes is defined. Through an analytical model, we show that the search time scales as N 1/D(D+1) for small-world networks, where N is the number of nodes and D is the dimension of the underlying lattice. This model is shown to be in agreement with numerical simulations

Networking Journalism Studies: Towards a World Journalism Survey

Directory of Open Access Journals (Sweden)

Thomas Hanitzsch

2007-12-01

Full Text Available Most scholars argue that cross-national research is indispensable for establishing the generalizability of theories and the validity of interpretations derived from single-nation studies. Another important aspect of comparative studies is that they force us to test our interpretations against cross-cultural diferences and inconsistencies. In journalism studies, the advantages of cross-national research are obvious. While the empirical inquiry into news-making has generated a vast quantity of data, some of the more fundamental questions in journalism research remain largely unresolved: What shapes the news and the structures of journalism most? Is it politics, economy, or culture? How do the conventional Western values of objective journalism ft in with non-Western cultures? In this article, I would like to propose the creation of a “World Journalism Survey”, modeled after the World Values Survey, for a better map of the cultural diferences in journalism practices around the world.

The Geometric Construction Abilities Of Gifted Students In Solving Real - World Problems: A Case From Turkey

2016-10-01

Full Text Available Geometric constructions have already been of interest to mathematicians. However, studies on geometric construction are not adequate in the relevant literature. Moreover, these studies generally focus on how secondary school gifted students solve non-routine mathematical problems. The present study aims to examine the geometric construction abilities of ninth-grade (15 years old gifted students in solving real-world geometry problems; thus a case study was conducted. Six gifted students participated in the study. The data consisted of voice records, solutions, and models made by the students on the GeoGebra screen. Results indicate that gifted students use their previous knowledge effectively during the process of geometric construction. They modeled the situations available in the problems through using mathematical concepts and the software in coordination. Therefore, it is evident that gifted students think more creatively while solving problems using GeoGebra.

It has become widely accepted that the discipline of International Relations (IR) is ironically not "international" at all. IR scholars are part of a global discipline with a single, shared object of study - the world, and yet theorizing gravitates around a number of concepts that have been...... conceived solely in the United States. The purpose of this book is to re-balance this "western bias" by examining the ways in which IR has evolved and is practiced around the world. The fifteen case studies offer fresh insights into the political and socioeconomic environments that characterize diverse...

Antihypertensive treatment with calcium channel blockers (CCBs) is consolidated in clinical practice; however, different studies observed increased risks of acute events for short-acting CCBs. This study aimed to provide real-world evidence on risks of acute cardiovascular (CV) events, hospitalizations and mortality among users of different CCB classes in secondary CV prevention. Three case-control studies were nested in a cohort of Italian elderly hypertensive CV-compromised CCBs users. Cases were subjects with CV events (n = 25,204), all-cause hospitalizations (n = 19,237), or all-cause mortality (n = 17,996) during the follow-up. Up to four controls were matched for each case. Current or past exposition to CCBs at index date was defined based on molecule, formulation and daily doses of the last CCB delivery. The odds ratio (OR) and 95% confidence intervals (CI) were estimated using conditional logistic regression models. Compared to past users, current CCB users had significant reductions in risks of CV events [OR 0.88 (95% CI: 0.84-0.91)], hospitalization [0.90 (0.88-0.93)] and mortality [0.48 (0.47-0.49)]. Current users of long-acting dihydropyridines (DHPs) had the lowest risk [OR 0.87 (0.84-0.90), 0.86 (0.83-0.90), 0.55 (0.54-0.56) for acute CV events, hospitalizations and mortality], whereas current users of short-acting CCBs had an increased risk of acute CV events [OR 1.77 (1.13-2.78) for short-acting DHPs; 1.19 (1.07-1.31) for short-acting non-DHPs] and hospitalizations [OR 1.84 (0.96-3.51) and 1.23 (1.08-1.42)]. The already-existing warning on short-acting CCBs should be potentiated, addressing clinicians towards the choice of long-acting formulations.

Houghton, Catherine; Murphy, Kathy; Shaw, David; Casey, Dympna

2015-05-01

To illustrate an approach to data analysis in qualitative case study methodology. There is often little detail in case study research about how data were analysed. However, it is important that comprehensive analysis procedures are used because there are often large sets of data from multiple sources of evidence. Furthermore, the ability to describe in detail how the analysis was conducted ensures rigour in reporting qualitative research. The research example used is a multiple case study that explored the role of the clinical skills laboratory in preparing students for the real world of practice. Data analysis was conducted using a framework guided by the four stages of analysis outlined by Morse ( 1994 ): comprehending, synthesising, theorising and recontextualising. The specific strategies for analysis in these stages centred on the work of Miles and Huberman ( 1994 ), which has been successfully used in case study research. The data were managed using NVivo software. Literature examining qualitative data analysis was reviewed and strategies illustrated by the case study example provided. Discussion Each stage of the analysis framework is described with illustration from the research example for the purpose of highlighting the benefits of a systematic approach to handling large data sets from multiple sources. By providing an example of how each stage of the analysis was conducted, it is hoped that researchers will be able to consider the benefits of such an approach to their own case study analysis. This paper illustrates specific strategies that can be employed when conducting data analysis in case study research and other qualitative research designs.

Three-Capital Approach to the Study of Young People who Excel in Vocational Occupations: A Case of WorldSkills Competitors and Entrepreneurship

Directory of Open Access Journals (Sweden)

Maia Chankseliani

2016-04-01

Full Text Available This paper examines the entrepreneurial inclinations of young people who achieved excellence in vocational occupations. We propose a three-capital approach to the study of entrepreneurship. Relying on the existing theories and original qualitative and quantitative data analyses, findings from interviews with 30 entrepreneurial and 10 non-entrepreneurial WorldSkills competitors show that psychological capital, social capital and human capital can be combined to explore how young people who excel in vocational occupations develop entrepreneurial mindsets. We show that training for and participation in the largest vocational skills event globally - WorldSkills competition - develops selected aspects of three capitals. However, we also discover that the entrepreneurial motivation precedes competitors' involvement with WorldSkills.

Dynamic Competition and Cooperation of Road Infrastructure Investment of Multiple Tourism Destinations: A Case Study of Xidi and Hongcun World Cultural Heritage

Directory of Open Access Journals (Sweden)

Jun Li

2015-01-01

Full Text Available The transportation infrastructure always plays an important role in the development of the local tourism. A system dynamics method incorporated with a destination choice model is proposed in this paper to analyze the dynamic impacts of transportation infrastructure on the tourism development, where multiple tourism destinations share a common market. Tourists’ destination choice behaviors are characterized by a multinomial logit choice model based on the utility of destinations, which depends heavily on the accessibility of destinations that the local administration has strong willingness to improve. The system dynamics method is used to model dynamic interactions among destinations and to simulate the dynamic evolution of the competition on the tourism market. A case study of the World Cultural Heritage Sites, Xidi and Hongcun villages, shows the competition for road infrastructure investment can produce a win-win situation and bring the cooperation on investment due to the positive externality of transport infrastructure and two villages show a tendency to merge into one bigger destination. Finally, the tourism development strategies for two villages are discussed based on the scenario analysis.

Pega, Frank; Veale, Jaimie F

2015-03-01

We analyzed the case of the World Health Organization's Commission on Social Determinants of Health, which did not address gender identity in their final report. We argue that gender identity is increasingly being recognized as an important social determinant of health (SDH) that results in health inequities. We identify right to health mechanisms, such as established human rights instruments, as suitable policy tools for addressing gender identity as an SDH to improve health equity. We urge the World Health Organization to add gender identity as an SDH in its conceptual framework for action on the SDHs and to develop and implement specific recommendations for addressing gender identity as an SDH.

Full Text Available The article is focused on the Black Sea Province rear activity in the First World War. The article is based on the data of local and regional periodical press, such as: «Chernomorsky Kray», «Sochinsky Listok», «Chernomorskoe Poberezh’e», «Chernomorsky Listok Voyny», etc. Among the rear area activities, we can name charity for the wounded, entertainment at military hospitals, foundation of Mercy Sisters schools and Red Cross regional offices. Attention is also attached to the interaction with state institutions in charge of hospital work and the attitude of the royal family towards hospital care. Red Cross activities in the First World War are also significant. The conclusion states that cooperation between centre and outskirts in terms of help for the wounded was close in the First World War. Almost all of the work, concerning the establishment of regional (province hospitals was charity-funded. Outskirts attempted to model the supreme authority behavior, concerning this question and as a result the care for war victims had become the duty of the whole Russian community.

Linking biomedical engineering ethics case study approach and policy.

Science.gov (United States)

Dibrell, William; Dobie, Elizabeth Ann

2007-01-01

In this paper we link bioengineering case study methods to the development of policy. The case study approach to ethics is an excellent way to show the complex nature of practical/moral reasoning. This approach can, however, lead to a kind of overwhelming complexity. The individual nature of each case makes it difficult to identify the most important information and difficult to see what moral considerations are most relevant. In order to make the overwhelming complexity less debilitating, we present a framework for moral decision making derived from suggestions made by W.D. Ross and Virginia Held. Ross articulates the multiple sources of morality and Held deepens the discussion by reminding us of the foundational importance of care and sympathy to our moral natures. We show how to use the notion of prima facie duty and discuss moral conflict. In doing this, we show how the framework, applied to cases, can be of assistance in helping us develop policies and codes of ethics with sufficient plasticity to be useful in the complex world of the bioengineer.

A number of people injured during the second world war harbour foreign bodies such as grenade splinters or bullets in some part of the body. Most of these metal fragments remain clinically silent. Some of them, however, may cause delayed complications. The purpose of this study was to determine the characteristics of delayed complications associated with foreign bodies after world war II injuries. 159 patients with retained foreign bodies after world war II injuries were retrospectively identified radiologically in our data bases in the time interval from 1997 to 2009. Diverse delayed complications secondary to the metal objects were diagnosed in 3 cases (2%): one patient with grenade splinter migration into the choledochal duct, one case with pseudotumoural tissue reaction, and one patient with late osteomyelitis. The time from injury to clinical presentation varied from 56 to 61 years. PubMed and Medline were screened for additional cases with delayed sequelae after foreign body acquisition during the 2nd world war. A 30 year search period from 1980 up to date was selected. 15 cases were identified here. Our study demonstrates that health consequences of the 2nd world war extend into the present time, and therefore physicians should be aware of the presence of hidden foreign bodies and their different possible late reactions.

Vulnerability and Inequality in an Increasingly Wetter World: A Namibia Case Study

Science.gov (United States)

Kelly, M.; Silva, J.; Mandl, D.; Sohlberg, R. A.

2016-12-01

Over the past two decades, Namibia has experienced increased instances of flooding that have grown in intensity and duration. Major flooding events in 2008 and 2009 displaced hundreds of thousands of people, causing thousands to remain in flood relocation camps for months at a time. Due to lack of topographic relief in the region, water tends to sit until it evaporates. Both inter-annual variability and changes in climate may lead to even greater rainfall and flooding in the future. In 2009, 29% of Namibians lived below the national poverty line (World Bank) and many make their living off of subsistence farming, as well as trading livestock. Using socio-economic data collected from the Namibia Household Income & Expenditure Survey (NHIES) reports by the Namibia Statistics Agency for the years 1993-1994, 2003-2004, and 2009-2010, and Landsat imagery for the corresponding years, we aim to characterize flood impact and flood vulnerability. Water coverage maps of Namibia were created for each time period using Landsat imagery overlain with socio-economic data to see how flooding impacts socio-variables such as income, inequality, access to livestock and grazing lands, and consumption over time. Because Namibia is not a data-rich environment, it is difficult to obtain the fine granularity of socio-data needed to put a dollar value on loss and vulnerability in flood prone areas. We hope the findings of this study will draw attention to these problems and allow us to access the data needed to more accurately characterize flood vulnerability in Namibia.

Researching virtual worlds methodologies for studying emergent practices

CERN Document Server

Phillips, Louise

2013-01-01

This volume presents a wide range of methodological strategies that are designed to take into account the complex, emergent, and continually shifting character of virtual worlds. It interrogates how virtual worlds emerge as objects of study through the development and application of various methodological strategies. Virtual worlds are not considered objects that exist as entities with fixed attributes independent of our continuous engagement with them and interpretation of them. Instead, they are conceived of as complex ensembles of technology, humans, symbols, discourses, and economic structures, ensembles that emerge in ongoing practices and specific situations. A broad spectrum of perspectives and methodologies is presented: Actor-Network-Theory and post-Actor-Network-Theory, performativity theory, ethnography, discourse analysis, Sense-Making Methodology, visual ethnography, multi-sited ethnography, and Social Network Analysis.

Case studies in organic contaminant hydrogeology

International Nuclear Information System (INIS)

Baker, J.A.

1989-01-01

The effective management of domestic solid waste and hazardous, toxic, and radioactive waste is a major problem in the area of environmental geology and water sciences throughout the world. A series of case studies is presented of organic contaminants from both solid and hazardous waste disposal facilities to provide examples of these problems. The facilities were investigated to determine risks and liabilities before acquisition, to determine the site hydrogeologic conditions for design of appropriate groundwater monitoring plans, and/or to determine the potential for groundwater contamination. The case studies are of disposal facilities located in glacial tills, carbonaceous weathered clay soils, weathered shale, limestone bedrock, dolomite bedrock, and alluvial and sedimentary deposits. The results of these studies and investigations show certain relationships in the distribution of organic pollutants to the different geologic and hydrogeologic characteristics of each facility. In each of the four case studies, all 129 priority pollutants were analyzed in private wells and/or monitoring wells. The 31 volatile organic compounds (VOCs) of the priority pollutant list were the majority of organic compounds detected. When VOCs are found in groundwater impacted by disposal facilities, they are present in groups and tend to be distributed in patterns based on their relative concentrations. It is rare to find only one or two VOCs from facilities where leakage has been detected. The ethylenes and ethanes appear to be more prevalent and mobile than aromatic VOCs. The aromatics are restricted primarily to leachates and wastes and in monitoring wells located adjacent to facilities. 2 refs., 15 figs

Scaling in small-world resistor networks

Korniss, G.; Hastings, M.B.; Bassler, K.E.; Berryman, M.J.; Kozma, B.; Abbott, D.

2006-01-01

We study the effective resistance of small-world resistor networks. Utilizing recent analytic results for the propagator of the Edwards-Wilkinson process on small-world networks, we obtain the asymptotic behavior of the disorder-averaged two-point resistance in the large system-size limit. We find that the small-world structure suppresses large network resistances: both the average resistance and its standard deviation approaches a finite value in the large system-size limit for any non-zero density of random links. We also consider a scenario where the link conductance decays as a power of the length of the random links, l -α . In this case we find that the average effective system resistance diverges for any non-zero value of α

Abshier, Patricia

2012-04-01

In a world where funding is limited, training for healthcare professionals is turning more and more to distance learning in an effort to maintain a knowledgeable and skilled work force. In 2010, Cicatelli Associates, Inc. began exploring the feasibility of using games and virtual worlds as an alternative means to teach skills-training in a distance-learning environment. The pilot study was conducted with six individuals familiar with general counseling and communication skills used by the healthcare industry to promote behavior change. Participants reported that the venue, although challenging at first, showed great potential for use with healthcare providers, as it allowed for more interaction and activities than traditional Webinars. However, there are significant limitations that must be overcome in order for this healthcare training modality to be utilized on a large scale. These limitations included a lack of microgestures and issues regarding the technology being used. In spite of the limitations, however, the potential use of virtual worlds for the training of healthcare providers exists and should be researched further. This article discusses the need and intended benefits of virtual world training as well as the results and conclusions of the pilot study.

Modern Standardization -- Case Studies at the Crossroads of Technology, Economics, and Politics covers the development of new technical standards, how these standards are typically triggered, and how they are submitted to standards development organizations (SDOs) for review and evaluation. It fills the gap in the shortage of reference material in the development of real-world standards. The increasing pace of innovation in technology has accelerated the competitive nature of standardization, particularly in emerging markets. Modern Standardization addresses these and other issues through a series of case studies in a format designed for academics and their engineering, business, and law school students.

ANALYSIS ON THE RELATIONSHIP BETWEEN THE PROFIT TAX AND INVESTMENTS IN THE CONTEXT OF A GLOBALISED WORLD. CASE STUDY – ROMANIA

2010-09-01

Full Text Available Although it is a relative old concept, having ruts in the writings of the late „60s, globalization has become in current times a cliché, being used in many parts of the world and in many languages but not having a specific definition. Financial globalization is considered to be the core element of the process of globalization and consists in a complex integration of financial markets through exchange and financial flows. In this context, the economic agents are considered to be important players, given the fact that fortheir investments they appeal to financial recourses wherever they may be. However there investment behavior is greatly influenced by the state, through the fiscal policy, especially through a very important instrument at its disposal, the profit tax rate.The aim of this paper is to emphasize the evolution of the relationship between the profit tax and investments, in the case of Romania from 1990 until 2008, trying to show particular developments of each of this two variables studied and the relations between them, the amplitude of influence exercised by them. The paper also focuses upon a better understanding of how the variables analyzed influence the real economy in this globalized environment.

The Rise of the Spirit of National Interest and the Existence of World Trade Organization Agreement: A Case Study of Indonesia

Full Text Available There has been an anxiety over the rise of the spirit of national interest on the existence of World Trade Organization. This spirit that has been reflected from domestic trade policy, to some extent, has undermined trade negotiation process under the WTO as shown by the failure of the Doha Round to conclude significant trade deals. Countries also started concluding bilateral and regional trade agreements instead of the WTO. This article aimed to analyze whether the rise of the spirit of national interest has threaten the existence of the WTO agreements, putting Indonesia as a case study. This article is a normative research, analyzing the dynamics development of the national interest under the WTO, especially Indonesia, and how the judicial body has responded the rise of this spirit in its decisions. This article argues that the spirit of national interest will not threaten the existence of WTO as this spirit has been exist from the early establishment of the General Agreement on Tariffs and Trade in 1947 to the latest WTO negotiation. Moreover, the existence of the WTO judicial body will secure the existence of the WTO, especially because it has successfully controlled the overwhelming spirit of national interest of its members through its decisions.

A multi-case study of school gardens in Southwest Montana

Science.gov (United States)

Yates, Kimberly Ann

Many children today spend little time outdoors exploring the natural world and a great deal of time inside viewing the television or playing video games. This new condition of childhood has many negative ramifications, such as poor social development, childhood obesity, and a lack of feeling connected to the environment. One instructional tool being used by some schools to address these rising concerns is a school garden. School gardens can provide an opportunity for students to experience learning in a real-world application, outside of the classroom walls. This qualitative multi-case study explores three school gardens in Southwest Montana and tells each of their unique stories. Through the process of participant observation, interviews, and the collection of multiple data sources, a thorough description is given of the history behind the gardens, how they have impacted the teachers and students, what challenges they have faced, and the common characteristics found in a successful school garden program. During the data analysis process, themes for each case study site were revealed. The results of this study found that each school garden was unique in character and purpose and that a number of dedicated garden supporters are essential to the success of a garden program. In conclusion, suggestions and resources were provided for practitioners interested in pursuing a garden program.

Elizabeth Pisani

2017-08-01

Full Text Available Background: Increasingly, biomedical researchers are encouraged or required by research funders and journals to share their data, but there's very little guidance on how to do that equitably and usefully, especially in resource-constrained settings. We performed an in-depth case study of one data sharing pioneer: the WorldWide Antimalarial Resistance Network (WWARN. Methods: The case study included a records review, a quantitative analysis of WAARN-related publications, in-depth interviews with 47 people familiar with WWARN, and a witness seminar involving a sub-set of 11 interviewees. Results: WWARN originally aimed to collate clinical, in vitro, pharmacological and molecular data into linked, open-access databases intended to serve as a public resource to guide antimalarial drug treatment policies. Our study describes how WWARN navigated challenging institutional and academic incentive structures, alongside funders' reluctance to invest in capacity building in malaria-endemic countries, which impeded data sharing. The network increased data contributions by focusing on providing free, online tools to improve the quality and efficiency of data collection, and by inviting collaborative authorship on papers addressing policy-relevant questions that could only be answered through pooled analyses. By July 1, 2016, the database included standardised data from 103 molecular studies and 186 clinical trials, representing 135,000 individual patients. Developing the database took longer and cost more than anticipated, and efforts to increase equity for data contributors are on-going. However, analyses of the pooled data have generated new methods and influenced malaria treatment recommendations globally. Despite not achieving the initial goal of real-time surveillance, WWARN has developed strong data governance and curation tools, which are now being adapted relatively quickly for other diseases. Conclusions: To be useful, data sharing requires

Anaphora resolution without world knowledge

Directory of Open Access Journals (Sweden)

Leffa Vilson J.

2003-01-01

Full Text Available A typical problem in the resolution of pronominal anaphora is the presence of more than one candidate for the antecedent of the pronoun. Considering two English sentences like (1 "People buy expensive cars because they offer more status" and (2 "People buy expensive cars because they want more status" we can see that the two NPs "people" and "expensive cars", from a purely syntactic perspective, are both legitimate candidates as antecedents for the pronoun "they". This problem has been traditionally solved by using world knowledge (e.g. schema theory, where, through an internal representation of the world, we "know" that cars "offer" status and people "want" status. The assumption in this paper is that the use of world knowledge does not explain how the disambiguation process works and alternative explanations should be explored. Using a knowledge poor approach (explicit information from the text rather than implicit world knowledge the study investigates to what extent syntactic and semantic constraints can be used to resolve anaphora. For this purpose, 1,400 examples of the word "they" were randomly selected from a corpus of 10,000,000 words of expository text in English. Antecedent candidates for each case were then analyzed and classified in terms of their syntactic functions in the sentence (subject, object, etc. and semantic features (+ human, + animate, etc.. It was found that syntactic constraints resolved 85% of the cases. When combined with semantic constraints the resolution rate rose to 98%. The implications of the findings for Natural Language Processing are discussed.

The Special Place Project: Efficacy of a Place-Based Case Study Approach for Teaching Geoscience

Science.gov (United States)

Moosavi, Sadredin

2014-05-01

Achieving geoscience literacy of the general population has become increasingly important world wide as ever more connected and growing societies depend more and more on our planet's limited natural resource base. Building citizen understanding of their dependence on the local environment, and the geologic processes which created and continue to change it, has become a great challenge to educators at all levels of the education system. The Special Place Project described in this presentation explores use of a place-based case study approach combining instruction in geoscience content with development of observation, reasoning, writing and presentation skills. The approach allows students to select the locations for their individual case studies affording development of personal connections between the learner and his environment. The approach gives instructors at many grade levels the ability to develop core pedagogical content and skills while exploring the unique geologic environments relevant to the local population including such critical issues as land use, resource depletion, energy, climate change and the future of communities in a changing world. The geologic reasons for the location of communities and key events in their histories can be incorporated into the students' case studies as appropriate. The project is unique in placing all course instruction in the context of the quest to explore and gain understanding of the student's chosen location by using the inherently more generalized course content required by the curriculum. By modeling how scientists approach their research questions, this pedagogical technique not only integrates knowledge and skills from across the curriculum, it captures the excitement of scientific thinking on real world questions directly relevant to students' lives, increasing student engagement and depth of learning as demonstrated in the case study reports crafted by the students and exam results.

2018-04-01

Full Text Available Human settlements are social-economic-natural complex ecosystems centered on human activities and the most prominent site for the contradictions between humans and the environment. Taking Hongcun, a UNESCO World Heritage site in China, as an example, this paper analyzes the methods and effect of coupling man and nature in Hongcun, summarizes the ecological wisdom of dealing with the relationship between human and nature, and uses this wisdom to shed light on the planning, construction, and management of contemporary urban and rural settlements. Firstly, the study introduces the Human-Natural Intergraded Ecological Planning (HNIEP model’s hypothesis, explaining its foundation and potential principles or approaches. Secondly, using the case study of Hongcun to explain, support, and validate the HNIEP model and its framework, the study found that the unique planning and construction of Hongcun has greatly promoted ecosystem services, such as local microclimate regulation, rainwater runoff regulation, water conservation, landscape aesthetic, and engagement with nature. Thirdly, Hongcun reflects the concept of harmonious coexistence between human and nature, the wisdom of rational use of ecosystem structures, processes and functions, and the wisdom of coupling human activities with the living environment and natural ecosystem. Finally, the paper summarizes the enlightenment brought by both the HNIEP model and Hongcun wisdom to contemporary urban-rural planning and construction management.

2017-11-01

Randomised clinical trials (RCTs) are considered the basis of evidence-based medicine. It is recognised more and more that application of RCT results in daily practice of clinical decision-making is limited because the RCT world does not correspond with the clinical real world. Recent strategies aiming at substitution of RCT databases by improved population-based registries (PBRs) or by improved electronic health record (EHR) systems to provide significant data for clinical science are discussed. A novel approach exemplified by the HemoBase haemato-oncology project is presented. In this approach, a PBR is combined with an advanced EHR, providing high-quality data for observational studies and support of best practice development. This PBR + EHR approach opens a perspective on randomised registry trials. Copyright © 2017 Elsevier Ltd. All rights reserved.

In this case study, a young women who has chronic verbal, emotional, and physical abuse and was exposed to repetitive adult acts of abuse as a child initially presented with Posttraumatic Stress Disorder (PTSD) marked by constriction and disconnection, which resulted in her feeling passive and tortured. As part of her occupational therapy intervention, based on the occupational adaptation, psychoanalytic, and recovery frames of reference, she was able to use her skills as a musician and lyricist to work through her trauma by performing heavy metal music. She used work to express emotions and tell and retell her story to audiences eager to hear her. Work helped her develop an identity that allowed her to be active in the world and reach out to others through her music. This case study focuses on the intervention - how music and occupation functioned as a foundation for relieving her PTSD.

Leon, P.T.; Cuesta, L.; Serra, E.; Yague, L.

2010-01-01

Life extension of nuclear power plants above 40 years of operation is an important issue in many countries. The Kyoto limits for CO 2 emissions, the security of supply, the costs of renewable energies and the economic crisis have pushed governments to continue operation of nuclear plants over the 40 years design life. In the Usa 59 units have obtained the extension of operation license from 40 to 60 years, and currently 19 units are in the reviewing process. The situation in the rest of the world is different. A list of countries, where nuclear units with a service life over 30 years, are still operating has been drawn up. A few countries like Belgium, Germany, Spain and Sweden are opposed to life extension. Some countries like Finland, the Netherlands, Switzerland, India, Japan and Usa, have adopted a life extension policy for their nuclear fleet. Other countries like France, Russia, United-Kingdom, Pakistan, South-Korea and Argentina have not yet taken any final decision. United-Kingdom and France have a case by case policy. In some countries like Japan, Indian or Pakistan, the legislation makes no reference to a maximum operating time but the reactors are allowed to continue operating as long as they comply with established safety conditions.

Dementia in retired boxers, also referred to as "dementia pugilistica" (DP), is usually attributed to repeated concussive and subconcussive blows to the head. We report the case of a former world boxing champion whose progressive cognitive decline could be ascribed to DP, cerebral infarcts and Wernicke-Korsakoff syndrome. This case demonstrates that dementia in retired boxers may be caused and/or exacerbated by etiologic factors other than DP. We correlated the clinical features with the histochemical and immunohistochemical changes observed on autopsy brain material from a retired boxer, reviewed the literature on boxing-related dementia, and compared our findings with previous reports on DP. Neuropathologic examination revealed numerous neurofibrillary tangles (NFTs), rare neuritic plaques (NPs), multiple cerebral infarcts, fenestrated septum pellucidum, atrophic and gliotic mamillary bodies, and pale substantia nigra and locus ceruleus. Our neuropathologic data confirmed the notion that dementia in retired boxers could be due to several factors such as DP, multiple cerebral infarcts and Wernicke-Korsakoff syndrome. Our findings illustrate the need to comprehensively examine former boxers with dementia as well as carefully evaluate the neuropathologic changes that may cause or contribute to the patient's cognitive and behavioral symptoms. Such an approach is crucial in order to provide prompt and more definitive therapies.

Full Text Available The large number of regional trade agreements notified to the World Trade Organization (WTO significantly influenced the flow of world trade. By April 2014 there had been notified 583 regional trade agreements to the WTO, of which only 379 are in force. The objective of this paper is to highlight the importance of regional trade agreements in world trade, especially the importance of establishing a regional competition policy in these agreements. The research methodology used is the analysis of legislation governing preferential trade agreements at the level of WTO, the collection and interpretation of statistical data provided by the WTO Secretariat, the case study, namely the study of literature. The paper is structured in three parts. The first part of the paper examines the basic laws based on which regional trade agreements are notified to the WTO and the evolution of these agreements in the period 1958-2013. The second part of the paper is devoted to the analysis of competition policy in regional trade agreements. In this part of the paper, to highlight the patterns of competition policy adopted under these agreements was analyzed by three case studies of competition policy in the EU, ASEAN and NAFTA. The three case studies have revealed that the three preferential trade agreements present regional competition policies with varying degrees of integration. The most complex form of competition policy is found in the European Union, because we are talking about a centralized model of competition policy. ASEAN presents a partially decentralized model, while NAFTA scrolls with a decentralized model of competition policy. The last part of the paper presents the characteristics of the four models of competition policy identified in the preferential trade agreements in force. It should be emphasized that if the initial preferential trade agreements have not put a great emphasis on the rules of competition policy, practice has shown the importance

World oil: the growing case for international policy

International Nuclear Information System (INIS)

Chapman, D.; Khanna, N.

2000-01-01

Can the economic theory of depletion be reconciled with low petroleum prices? This article uses a revision of the theory, which reflects demand functions that rise in response to increasing world population and income. The magnitude of producers' and consumers' surplus is estimated under both competitive and monopolistic assumptions; the result indicates a present value comparable to or in excess of today's gross world economic product. Game theory suggests a framework that explains the interaction between oil pricing and military policy, and the economic incentives that result in a general pattern of recent market equilibrium crude oil prices often fluctuating with a 15-20 US dollars per barrel range. The analysis concludes that the economic incentives for political instability in the Persian Gulf will increase, and more formal methods of setting the international framework for Persian Gulf oil may be expected.

Gordon, B. L.; Ajami, N.; Quesnel, K.

2017-12-01

Aging infrastructure, population growth, and urbanization are demanding new approaches to management of all components of the urban water cycle, including stormwater. Traditionally, urban stormwater infrastructure was designed to capture and convey rainfall-induced runoff out of a city through a network of curbs, gutters, drains, and pipes, also known as grey infrastructure. These systems were planned with a single-purpose and designed under the assumption of hydrologic stationarity, a notion that no longer holds true in the face of a changing climate. One solution gaining momentum around the world is green infrastructure (GI). Beyond stormwater quality improvement and quantity reduction (or technical benefits), GI solutions offer many environmental, economic, and social benefits. Yet many practical barriers have prevented the widespread adoption of these systems worldwide. At the center of these challenges is the inability of stakeholders to know how to monitor, measure, and assess the multi-sector performance of GI systems. Traditional grey infrastructure projects require different monitoring strategies than natural systems; there are no overarching policies on how to best design GI monitoring and evaluation systems and measure performance. Previous studies have attempted to quantify the performance of GI, mostly using one evaluation method on a specific case study. We use a case study approach to address these knowledge gaps and develop a conceptual model of how to evaluate the performance of GI through the lens of financing. First, we examined many different case studies of successfully implemented GI around the world. Then we narrowed in on 10 exemplary case studies. For each case studies, we determined what performance method the project developer used such as LCA, TBL, Low Impact Design Assessment (LIDA) and others. Then, we determined which performance metrics were used to determine success and what data was needed to calculate those metrics. Finally, we

This case study of the Argentina Road Safety Project demonstrates how the application of World Bank road safety project guidelines focused on institution building can accelerate knowledge transfer, scale up investment and improve the focus on results. The case study highlights road safety as a development priority and outlines World Bank initiatives addressing the implementation of the World Report on Road Traffic Injury's recommendations and the subsequent launch of the Decade of Action for Road Safety, from 2011-2020. The case study emphasizes the vital role played by the lead agency in ensuring sustainable road safety improvements and promoting the shift to a 'Safe System' approach, which necessitated the strengthening of all elements of the road safety management system. It summarizes road safety performance and institutional initiatives in Argentina leading up to the preparation and implementation of the project. We describe the project's development objectives, financing arrangements, specific components and investment staging. Finally, we discuss its innovative features and lessons learned, and present a set of supplementary guidelines, both to assist multilateral development banks and their clients with future road safety initiatives, and to encourage better linkages between the health and transportation sectors supporting them.

Transportation Structure Analysis Using SD-MOP in World Modern Garden City: A Case Study in China

Directory of Open Access Journals (Sweden)

2012-01-01

Full Text Available The idea of the “garden city” was developed theoretically to offer solutions to serious city development problems such as traffic congestion, population, and environmental pollution, among which the transportation is considered the most important. The question is how to develop balanced transportation in a garden city. Transportation is a complex system, particularly in a garden city. Therefore, we establish a new approach named the transportation multiobjective optimization system dynamics  (SD-MOP model, which firstly calculates the optimal proportion of different transport means with an MOP approach and then applies them to the dynamic transportation system to analyze the results and analyze the influence on the whole system using different transportation means variation. In this paper, we take Chengdu as an example, one of the few cities in the world declared as building a garden city, and then develop some recommendations about world modern garden city transportation system development.

2017-01-01

The comparative analysis of world music cultures has been the focus of several ethnomusicological studies in the last century. With the advances of Music Information Retrieval and the increased accessibility of sound archives, large-scale analysis of world music with computational tools is today feasible. We investigate music similarity in a corpus of 8200 recordings of folk and traditional music from 137 countries around the world. In particular, we aim to identify music recordings that are most distinct compared to the rest of our corpus. We refer to these recordings as ‘outliers’. We use signal processing tools to extract music information from audio recordings, data mining to quantify similarity and detect outliers, and spatial statistics to account for geographical correlation. Our findings suggest that Botswana is the country with the most distinct recordings in the corpus and China is the country with the most distinct recordings when considering spatial correlation. Our analysis includes a comparison of musical attributes and styles that contribute to the ‘uniqueness’ of the music of each country. PMID:29253027

de Chadarevian, Soraya

2015-01-01

This essay draws attention to the role of the WHO in shaping research agendas in the biomedical sciences in the postwar era. It considers in particular the genetic studies of human populations that were pursued under the aegis of the WHO from the late 1950s to 1970s. The study provides insights into how human and medical genetics entered the agenda of the WHO. At the same time, the population studies become a focus for tracking changing notions of international relations, cooperation, and development and their impact on research in biology and medicine in the post-World War I era. After a brief discussion of the early history of the WHO and its position in Cold War politics, the essay considers the WHO program in radiation protection and heredity and how the genetic study of "vanishing" human populations and a world-wide genetic study of newborns fitted this broader agenda. It then considers in more detail the kind of support offered by the WHO for these projects. The essay highlights the role of single individuals in taking advantage of WHO support for pushing their research agendas while establishing a trend towards cooperative international projects in biology.

The case-control methodology is frequently used to evaluate vaccine effectiveness post-licensure. The results of such studies provide important insight into the level of protection afforded by vaccines in a 'real world' context, and are commonly used to guide vaccine policy decisions. However, the potential for bias and confounding are important limitations to this method, and the results of a poorly conducted or incorrectly interpreted case-control study can mislead policies. In 2012, a group of experts met to review recent experience with case-control studies evaluating vaccine effectiveness; we summarize the recommendations of that group regarding best practices for data collection, analysis, and presentation of the results of case-control vaccine effectiveness studies. Vaccination status is the primary exposure of interest, but can be challenging to assess accurately and with minimal bias. Investigators should understand factors associated with vaccination as well as the availability of documented vaccination status in the study context; case-control studies may not be a valid method for evaluating vaccine effectiveness in settings where many children lack a documented immunization history. To avoid bias, it is essential to use the same methods and effort gathering vaccination data from cases and controls. Variables that may confound the association between illness and vaccination are also important to capture as completely as possible, and where relevant, adjust for in the analysis according to the analytic plan. In presenting results from case-control vaccine effectiveness studies, investigators should describe enrollment among eligible cases and controls as well as the proportion with no documented vaccine history. Emphasis should be placed on confidence intervals, rather than point estimates, of vaccine effectiveness. Case-control studies are a useful approach for evaluating vaccine effectiveness; however careful attention must be paid to the collection

Full Text Available Eating disorders lead to special biological and psychological states. The result of the total lack of food is treated in a distinct way by anorexia. Nutritionists have thus had difficulty in coming to an agreement on the best therapy to prevent such disorders. First it is essential to understand which treatment aims are and then to attempt to know how the several treatment models used nowadays can reach those aims. Someone who suffers from eating disorders, together with an inner deformation, suffers from too much sensitiveness. In order to solve these problems, one needs a change in the relationship with oneself, with the others and with the world. This study presents a teenager’s case study – Anorexia. Is, in fact, a problem that society faces and can’t ignore. Many youngsters have already died and others are following their steps. But there are also those ones that succeeded in overcoming the problem and now are reporting their stories.

Richards, Ted

2017-01-01

Science is the most reliable means available for understanding the world around us and our place in it. But, since science draws conclusions based on limited empirical evidence, there is always a chance that a scientific inference will be incorrect. That chance, known as inductive risk, is endemic to science. Though inductive risk has always been present in scientific practice, the role of values in responding to it has only recently gained extensive attention from philosophers, scientists, and policy-makers. Exploring Inductive Risk brings together a set of eleven concrete case studies with the goals of illustrating the pervasiveness of inductive risk, assisting scientists and policymakers in responding to it, and moving theoretical discussions of this phenomenon forward. The case studies range over a wide variety of scientific contexts, including the drug approval process, high energy particle physics, dual-use research, climate science, research on gender disparities in employment, clinical trials, and to...

The Grose River is contained almost entirely within a World Heritage Area. While sewage pollution in the area has been addressed, pollution at damaging levels continues from a disused coal mine, closed in 1997. Despite some surface rehabilitation, no action has occurred to remediate zinc polluted waters emanating from the mine. We examine the historical regulation and management of the Australian Commonwealth and New South Wales governments and highlight gaps in both regulatory systems. We conclude that there is an urgent need to improve regulation of water pollution, mining and management of the environment in highly valued world heritage areas.

Yogic breathing and Ayurveda in aphasia: a case study.

Mohapatra, Bijoyaa; Marshall, Rebecca Shisler; Laures-Gore, Jacqueline

2014-01-01

We present a case study of a woman who used yogic breathing as Ayurvedic medicine in her recovery from poststroke aphasia. Ayurvedic medicine is one of the most ancient medicines of the world, but it is not widely used for aphasia rehabilitation in many Western countries. The description of this case aims to further the understanding of the benefits that this type of medicine may provide to poststroke patients living with aphasia. After her stroke, the patient received brief conventional language therapy for her aphasia. At 5 weeks post stroke, she received no further conventional rehabilitation; instead, she consulted with a Vedic priest. She followed a regimen of different body manipulations, yogic breathing techniques, and ingestion of coconut oil. Cognitive and language testing was performed throughout a 3-month period while she was involved in this therapy. Overall, improvement was noted in language, visual attention, and some mood measures. Although case studies lead to limited conclusions, changes were observed for this individual using Ayurvedic medicine. Given the changes in language and some aspects of cognition seen in this patient, further exploration of the effectiveness of yogic breathing and Ayurvedic medicine in the treatment of poststroke aphasia is warranted.

Fan filmmaking and copyright in a global world: Warhammer 40,000 fan films and the case of Damnatus

John Walliss

2010-09-01

Full Text Available The last decade has witnessed a proliferation, both online and off-line, of films produced by amateurs inspired by mainstream films, TV shows, and novels. As with much other fan production, fan films exist in, at best, a legally gray area since they are produced by amateurs, rather than by the media companies that own the copyrights to the films and novels that provide both their inspiration and settings. I examine the phenomenon of fan filmmaking, focusing on films produced by fans of the Warhammer 40,000 (W40K tabletop battle game. In particular, I examine the case of Damnatus: The Enemy Within (Damnatus: Feind Im Innern, 2005, a German-made fan film set in the W40K universe, which was banned from release by the game's rights holder, the UK company Games Workshop, in 2007. Damnatus offers an interesting case study in both the ongoing struggle between rights holders and textual poachers and the tensions that can exist between different legal understandings of copyright in an increasingly globalized world.

Snowboard cross (SBX) became an official Olympic sport in 2006. This discipline includes manoeuvring several obstacles while competing in heats. It is common for the riders to collide, making this sport both exciting and at risk of injuries. Although a recent study from the 2010 Olympic Games has shown that the injury risk was high, little is known about the injury mechanisms. To qualitatively describe the injury situation and mechanism of injuries in World Cup Snowboard Cross. Descriptive video analysis. Nineteen video recordings of SBX injuries reported through the International Ski Federation Injury Surveillance System for four World Cup seasons (2006 to 2010) were obtained. Five experts in the field of sports medicine, snowboard and biomechanics performed analyses of each case to describe the injury mechanism in detail (riding situation and rider behaviour). Injuries occurred at jumping (n=13), bank turning (n=5) or rollers (n=1). The primary cause of the injuries was a technical error at take-off resulting in a too high jump and subsequent flat-landing. The rider was then unable to recover leading to fall at the time of injury. Injuries at bank turn was characterised by a pattern where the rider in a balanced position lost control due to unintentional contact with another rider. Jumping appeared to be the most challenging obstacle in SBX, where a technical error at take-off was the primary cause of the injuries. The second most common inciting event was unintentional board contact between riders at bank turning.

Rasheva, E. A.

2015-12-01

For decades, role-play and simulation exercises have been utilized for learning and policy decision making. While the power of Model UN simulations in building first-person experience and understanding of complex international issues is well known, the effectiveness of simulations for inspiring citizen engagement in scientific public-policy issues is little studied. My work hypothesizes that climate-change negotiation simulations can enhance students' scientific literacy and policy advocacy. It aims to determine how age and gender influence the responsiveness of students to such simulations. During the 2015 fall semester, I am conducting World Climate exercises for fellow graduate and undergraduate students at San Francisco State University. At the end of the exercise, I will have collected the responses to an anonymous questionnaire in which the participants indicate age and gender. The questionnaire asks participants to describe their hopes and fears for the future and to propose public and personal actions for achieving a strong climate change agreement. I am tracking differences to determine whether participants' age and gender correlate with particular patterns of feeling and thinking. My future research will aim to determine whether and how strongly the World Climate Exercise has affected participants' actual policy engagement. This work will also reflect on my experiences as a World Climate facilitator. I will describe the facilitation process and then discuss some of my observations from the sessions. I will specify the challenges I have encountered and suggest strategies that can strengthen the learning process. World Climate is a computer-simulation-based climate change negotiations role-playing exercise developed by Climate Interactive in partnership with the System Dynamics Group at the MIT Sloan School of Management.

Life extension of Nuclear Power Plants above 40 years of operation is an important issue in many countries. The Kyoto limits for CO 2 emissions, the security of supply, the costs and predictability of renewable energy, etc., are putting nuclear energy in the agenda of many countries all around the world. The delay, due to the economic crisis, of the new nuclear projects in many countries, push governments to continue operation of nuclear plants above the 40 years design life. This is the case in the USA, where 59 units have obtained the extension of operation license from 40 to 60 years, and currently have 19 units are in the reviewing process. The life extension of these plants permits savings in CO 2 emissions and in the consumption of additional amounts of fossil fuels. In this paper, the position of the different nuclear countries about the Extension of Life will be reviewed, with a special emphasis on the situation in the USA. In this last case, the NRC approach for operation licenses above 40 years will be explained, and actions taken by nuclear companies in the country will be reviewed. In this country, the debate about life extension over 40 years has been surpassed, and the new technical discussion focuses on the operation of nuclear power plants above 60 years. (authors)

Full Text Available In the global economy, the market occupies a representative place because the grain is grown on a large area and it is important both to ensure food security and safety, but also for animal feed. In order to accomplish this study we have used certain indicators, of which the most representative are: acreage, production obtained, yield per hectare, food consumption, imports, exports and last but not least the price. World market of cereals has increased in the past decade due to increased consumption of cereals, especially in less developed countries economically. World grain market evolution in the analyzed period was disrupted on one side by the global economic crisis and on the other side by bad weather changes that occur on a global scale and have had a negative impact on acreage, production achieved, prices etc. According to forecasts the global market for cereals is expected to increase trade with cerereale, while diminishing stocks.

CERN Document Server

2016-01-01

Social innovators and social entrepreneurs look for creative and affordable solutions to specific societal problems. Fueled by the spread of the internet and the ubiquity of cell phones, it is easier than ever before to attempt to solve pressing social and environmental problems in the world. "Social Entrepreneurship and Innovation" presents the journeys of pioneering and often accidental social innovators who used their courage, tenacity, and creative thinking to find a solution to their problem. The case studies do not gloss over the setbacks and dead ends these people faced; instead, they offer a realistic insight into the challenges and mindset needed to overcome them. From bringing solar-powered lighting to Nigerian midwives, to using surplus food to reconnecting broken refugee families, each case draws out the lessons learned and provides guidance and advice for anyone inspired to take action of their own.

Full Text Available Purpose: To provide insights into the energy requirements as well as the physiological adaptations of an experienced 50-year-old ultra-marathon male athlete during the world's most challenging mountain ultra-marathon (MUM.Methods: The international race supporting the study was the Tor des Geants®, characterized by 330 km with +24,000 m D+ to be covered within 150 h. Before the MUM, we assessed the peak oxygen uptake (V˙O2peak by means of an incremental graded running test. During the MUM we monitored six ascents (once per race day with a portable gas analyzer, a GPS and a finger pulse oximeter. We then calculated the net metabolic cost per unit of distance (C, the vertical metabolic cost (Cvert and the mechanical efficiency of locomotion (Effmech throughout the six uphills monitored. We further monitored the distance covered, speed, altimetry and D+ from the GPS data as well as the pulse oxygen saturation with the finger pulse oximeter.Results: Subject's V˙O2peak was 48.1 mL·kg−1·min−1. Throughout the six uphills investigated the mean exercise intensity was 57.3 ± 6.0% V˙O2peak and 68.0 ± 8.7% HRpeak. C, Cvert and Effmech were 11.4 ± 1.9 J·kg−1·m−1, 57.9 ± 15.2 J·kg−1·mvert−1, and 17.7 ± 4.8%, respectively. The exercise intensity, as well as C, Cvert, and Effmech did not consistently increase during the MUM.Conclusions: For the first time, we described the feasibility of assessing the energy requirements as well as the physiological adaptations of a MUM in ecologically valid environment settings. The present case study shows that, despite the distance performed during the MUM, our participant did not experience a metabolic fatigue state. This is likely due to improvements in locomotor efficiency as the race progressed.

Do countries rely on the World Health Organization for translating research findings into clinical guidelines? A case study.

The World Health Organization's (WHO) antiretroviral therapy (ART) guidelines have generally been adopted rapidly and with high fidelity by countries in sub-Saharan Africa. Thus far, however, WHO has not published specific guidance on nutritional care and support for (non-pregnant) adults living with HIV despite a solid evidence base for some interventions. This offers an opportunity for a case study on whether national clinical guidelines in sub-Saharan Africa provide concrete recommendations in the face of limited guidance by WHO. This study, therefore, aims to determine if national HIV treatment guidelines in sub-Saharan Africa contain specific guidance on nutritional care and support for non-pregnant adults living with HIV. We identified the most recent national HIV treatment guidelines in sub-Saharan African countries with English as an official language. Using pre-specified criteria, we determined for each guideline whether it provides guidance to clinicians on each of five components of nutritional care and support for adults living with HIV: assessment of nutritional status, dietary counseling, micronutrient supplementation, ready-to-use therapeutic or supplementary foods, and food subsidies. We found that national HIV treatment guidelines in sub-Saharan Africa generally do not contain concrete recommendations on nutritional care and support for non-pregnant adults living with HIV. Given that decisions on nutritional care and support are inevitably being made at the clinician-patient level, and that clinicians have a relative disadvantage in systematically identifying, summarizing, and weighing up research evidence compared to WHO and national governments, there is a need for more specific clinical guidance. In our view, such guidance should at a minimum recommend daily micronutrient supplements for adults living with HIV who are in pre-ART stages, regular dietary counseling, periodic assessment of anthropometric status, and additional nutritional

Exploitation of the Virtual Worlds in Tourism and Tourism Education

Directory of Open Access Journals (Sweden)

Zejda Pavel

2016-12-01

Full Text Available Academics perceive a great potential of virtual worlds in various areas, including tourism and education. Efforts adapting the virtual worlds in practice are, however, still marginal. There is no clear definition of the virtual world. Therefore the author of this article attempts to provide one. The paper also focuses on the barriers of a wider exploitation of the virtual worlds and discusses the principles that might help to increase their potential in tourism area. One of the principles – gamification – favours a wider adaptation of the virtual worlds in tourism. Applying gamification principles provides visitors with some unique experiences while serving as a powerful marketing tool for institutions. The benefits of implementing tourism education activities based on cooperative principles set in an immersive environment of the virtual worlds are depicted afterwards. Finally, this paper includes successful case studies, which show advantages and drawbacks of some approaches in exploiting the virtual worlds in tourism and tourism education.

Randviir, Edward P; Illingworth, Samuel M; Baker, Matthew J; Cude, Matthew; Banks, Craig E

2015-01-01

The Royal Society of Chemistry held, to our knowledge, the world's first Twitter conference at 9am on February 5 (th), 2015. The conference was a Twitter-only conference, allowing researchers to upload academic posters as tweets, replacing a physical meeting. This paper reports the details of the event and discusses the outcomes, such as the potential for the use of social media to enhance scientific communication at conferences. In particular, the present work argues that social media outlets such as Twitter broaden audiences, speed up communication, and force clearer and more concise descriptions of a researcher's work. The benefits of poster presentations are also discussed in terms of potential knowledge exchange and networking. This paper serves as a proof-of-concept approach for improving both the public opinion of the poster, and the enhancement of the poster through an innovative online format that some may feel more comfortable with, compared to face-to-face communication.

Teaching Mathematical Modelling for Earth Sciences via Case Studies

Science.gov (United States)

Yang, Xin-She

2010-05-01

Mathematical modelling is becoming crucially important for earth sciences because the modelling of complex systems such as geological, geophysical and environmental processes requires mathematical analysis, numerical methods and computer programming. However, a substantial fraction of earth science undergraduates and graduates may not have sufficient skills in mathematical modelling, which is due to either limited mathematical training or lack of appropriate mathematical textbooks for self-study. In this paper, we described a detailed case-study-based approach for teaching mathematical modelling. We illustrate how essential mathematical skills can be developed for students with limited training in secondary mathematics so that they are confident in dealing with real-world mathematical modelling at university level. We have chosen various topics such as Airy isostasy, greenhouse effect, sedimentation and Stokes' flow,free-air and Bouguer gravity, Brownian motion, rain-drop dynamics, impact cratering, heat conduction and cooling of the lithosphere as case studies; and we use these step-by-step case studies to teach exponentials, logarithms, spherical geometry, basic calculus, complex numbers, Fourier transforms, ordinary differential equations, vectors and matrix algebra, partial differential equations, geostatistics and basic numeric methods. Implications for teaching university mathematics for earth scientists for tomorrow's classroom will also be discussed. Refereces 1) D. L. Turcotte and G.

International Nuclear Information System (INIS)

2003-01-01

This paper comments the different points of the reference scenario described in the WETO study (World energy, technology and climate policy outlook). This scenario describes a world energy situation, assuming a continuation of the present day trends and structural changes. A comment is made for each of the following aspects of the scenario: world energy demand, share of fossil fuels in the world energy supplies, world CO 2 emissions, petroleum reserves, world petroleum, gas and coal productions, petroleum and gas prices trend, end-use energy demand, power production and natural gas share in power generation. Then, the document analyses the impact of changes linked with hydrocarbon resources and technology developments: reduction of hydrocarbon resources, increase of gas resources, acceleration of technological developments in power generation. A third part analyzes the natural gas market of the European Union in a world perspective: market, reserves, demand, supply risks. Finally, the last part presents the impact of environmental policies in the case of a CO 2 tax and in the case of a carbon abatement scenario. (J.S.)

Pollination networks of oil-flowers: a tiny world within the smallest of all worlds.

Science.gov (United States)

Bezerra, Elisângela L S; Machado, Isabel C; Mello, Marco A R

2009-09-01

1. In the Neotropics, most plants depend on animals for pollination. Solitary bees are the most important vectors, and among them members of the tribe Centridini depend on oil from flowers (mainly Malpighiaceae) to feed their larvae. This specialized relationship within 'the smallest of all worlds' (a whole pollination network) could result in a 'tiny world' different from the whole system. This 'tiny world' would have higher nestedness, shorter path lengths, lower modularity and higher resilience if compared with the whole pollination network. 2. In the present study, we contrasted a network of oil-flowers and their visitors from a Brazilian steppe ('caatinga') to whole pollination networks from all over the world. 3. A network approach was used to measure network structure and, finally, to test fragility. The oil-flower network studied was more nested (NODF = 0.84, N = 0.96) than all of the whole pollination networks studied. Average path lengths in the two-mode network were shorter (one node, both for bee and plant one-mode network projections) and modularity was lower (M = 0.22 and four modules) than in all of the whole pollination networks. Extinctions had no or small effects on the network structure, with an average change in nestedness smaller than 2% in most of the cases studied; and only two species caused coextinctions. The higher the degree of the removed species, the stronger the effect and the higher the probability of a decrease in nestedness. 4. We conclude that the oil-flower subweb is more cohesive and resilient than whole pollination networks. Therefore, the Malpighiaceae have a robust pollination service in the Neotropics. Our findings reinforce the hypothesis that each ecological service is in fact a mosaic of different subservices with a hierarchical structure ('webs within webs').

Report on decision-making of geological disposal. Discussion based on case study

History of geological disposal from 1950 to 2000 in the world and some examples of change of policy in France, Sweden and Canada are explained. On the case study of three countries, investigations of background of the change, site decision process, communication, flexible concept of disposal are stated. Japan decided the high level radioactive waste is disposed in underground (300m deeper) under the Law Concerning the Final Disposal of Special Radioactive Waste in June, 2000. NUMO (Nuclear Waste Management Organization of Japan) was established to manage disposal of radioactive waste in October, 2000. NUMO started to accept application for the site of disposal in the country in December, 2002. The above case study is a good guide to promote geological disposal of radioactive waste. (S.Y.)

Long-term outlook for world gas trade: 1920-2015

International Nuclear Information System (INIS)

MacDougall, M.W.; Linder, P.T.

1992-01-01

The World Gas Trade Model (WGTM) was designed to simulate the economic relationships of world and regional gas markets. Using the data gathered for supply, transportation and demand, the model calculated a consistent set of prices and quantities that, through time, would simultaneously satisfy all physical, behavioural and financial relations embodied in the model network. Three sensitivity cases were examined. The first one examined the effects on world gas supply, demand and trade with oil prices remaining constant throughout the study period. The second sensitivity case examined the effects of lower costs of new liquefied natural gas (LNG) liquefaction facilities. The third sensitivity case examined the effects of policy shifts in favour of natural gas over other fossil fuels for environmental reasons. During the 25-year period of the study, global production of natural gas was projected to almost double, with the overall level of final consumption being very similar to production. Results indicated that natural gas would remain predominantly a regionally traded commodity. The relatively high cost of natural gas transportation was shown to provide a substantial competitive advantage to local producers compared to more distant competitors. The cost of new liquefaction facilities was not considered to be competitive with long distance pipeline transportation. The model also indicated that reducing transportation costs or increasing the wellhead price differential between exporting and importing regions would accelerate the development of global natural gas trade. figs., tabs., refs

Abu Bakar Abdul Rahim

2013-12-01

Full Text Available The increasing competition and commercialization of higher education has led to the internationalization of Higher Education Institutions (HEIs around the world. While internationalization appears to be inevitable, differences are apparent in its definitions, depth, scope and mode. The main aim of this paper is to assess the internationalization efforts of Malaysian HEIs through a case study on the internationalization process of one private HEI. The case highlights various weaknesses of the internationalization effort in the institution. The symptoms and the causes of the problems in the institution corroborate similar findings in other studies involving the internationalization of HEIs. Suggestions and recommendations are presented to enable other organizations that wish to undertake similar internationalization efforts to learn from the case study institution’s experience.

Indonesia is ranked as the 4th highest contributor to tuberculosis (TB) in the world. Semarang District in Central Java displays extremely low case detection rate (CDR), possibly contributing to the local prevalence of TB. A case-control study was performed to explore the factors that cause such low CDR. We recruited 129 TB cases and 83 controls that visited the same centers and were not diagnosed with TB. The cases had 7.5 ± 2.3 symptoms/person on average, indicating the delay in diagnosis because the controls only displayed 1.0 ± 1.7. The multiple logistic regression analysis comparing the cases/controls extracted following factors as a risk to have TB: farmer, close contact with TB patients, ignorance of whether Bacillus Calmette-Guérin (BCG) was accepted or no, smoking, low income, a lot of people living in the same room, irregular hand wash before meals, not wash hands after blow, soil floor, and no sunlight and no ventilation in the house. Neither the cases nor the controls knew the symptoms and how to avoid TB infection, which probably caused the delay in diagnosis. It is difficult to change the current living conditions. Thus, the amendment of the community-based education program of TB seems to be required.

Estimating Forest Aboveground Biomass by Combining ALOS PALSAR and WorldView-2 Data: A Case Study at Purple Mountain National Park, Nanjing, China

Directory of Open Access Journals (Sweden)

Songqiu Deng

2014-08-01

Full Text Available Enhanced methods are required for mapping the forest aboveground biomass (AGB over a large area in Chinese forests. This study attempted to develop an improved approach to retrieving biomass by combining PALSAR (Phased Array type L-band Synthetic Aperture Radar and WorldView-2 data. A total of 33 variables with potential correlations with forest biomass were extracted from the above data. However, these parameters had poor fits to the observed biomass. Accordingly, the synergies of several variables were explored to identify improved relationships with the AGB. Using principal component analysis and multivariate linear regression (MLR, the accuracies of the biomass estimates obtained using PALSAR and WorldView-2 data were improved to approximately 65% to 71%. In addition, using the additional dataset developed from the fusion of FBD (fine beam dual-polarization and WorldView-2 data improved the performance to 79% with an RMSE (root mean square error of 35.13 Mg/ha when using the MLR method. Moreover, a further improvement (R2 = 0.89, relative RMSE = 17.08% was obtained by combining all the variables mentioned above. For the purpose of comparison with MLR, a neural network approach was also used to estimate the biomass. However, this approach did not produce significant improvements in the AGB estimates. Consequently, the final MLR model was recommended to map the AGB of the study area. Finally, analyses of estimated error in distinguishing forest types and vertical structures suggested that the RMSE decreases gradually from broad-leaved to coniferous to mixed forest. In terms of different vertical structures (VS, VS3 has a high error because the forest lacks undergrowth trees, while VS4 forest, which has approximately the same amounts of stems in each of the three DBH (diameter at breast height classes (DBH > 20, 10 ≤ DBH ≤ 20, and DBH < 10 cm, has the lowest RMSE. This study demonstrates that the combination of PALSAR and WorldView-2 data

Iriarte, Alfredo; Almeida, Maria Gabriela; Villalobos, Pablo

2014-02-15

Nowadays, the new international market demands challenge the food producing countries to include the measurement of the environmental impact generated along the production process for their products. In order to comply with the environmentally responsible market requests the measurement of the greenhouse gas emissions of Ecuadorian agricultural goods has been promoted employing the carbon footprint concept. Ecuador is the largest exporter of bananas in the world. Within this context, this study is a first assessment of the carbon footprint of the Ecuadorian premium export banana (Musa AAA) using a considerable amount of field data. The system boundaries considered from agricultural production to delivery in a European destination port. The data collected over three years permitted identifying the hot spot stages. For the calculation, the CCaLC V3.0 software developed by the University of Manchester is used. The carbon footprint of the Ecuadorian export banana ranged from 0.45 to 1.04 kg CO2-equivalent/kg banana depending on the international overseas transport employed. The principal contributors to the carbon footprint are the on farm production and overseas transport stages. Mitigation and reduction strategies were suggested for the main emission sources in order to achieve sustainable banana production. Copyright © 2013 Elsevier B.V. All rights reserved.

ELECTRONIC RETAILING IN MACEDONIA-CASE STUDY OF OHRID REGION

2017-04-01

Full Text Available With electronic retailing that offers the possibility of direct sales, is no longer need expensive business premises, or paying high rents, or employing a number of vendors. There is also the possibility of selling to final consumers in any geographical region in different countries of the world by establishing instant communication, through presenting an interactive multimedia catalog that can offer numerous information то the customers. However, on the other hand, sales through the Internet can appear certain problems. Many potential buyers in the world still do not use the Internet, others don't have fast connections, others do not speak good English, also it requires the existence of trust between both parties, buyer and seller, as well as security in the execution of transactions. The aim of this paper is to treat electronic retailing in Macedonia which is becoming more popular as worldwide, especially in developed parts of the world like the US and Europe. Macedonian companies are increasingly applying electronic method of sale and communication with customers. The number of Internet users and on-line purchase is rapidly expanding what undoubtedly indicates that there is potential for advancement in this field. Also in this paper will be presented a case study where will be analyzed the current state for development of electronic retailing in Macedonia, especially region of Ohrid.

Case studies and case reports form an important and ever growing part of scientific and scholarly literature. The paper deals with the share and citation rate of these publication types on different fields of research. In general, evidence seems to support the opinion that an excessive number of such publications may negatively influence the impact factor of the journal. In the literature of scientometrics, case studies (at least the presence of the term "case study" in the titles of the papers) have a moderate share, but their citation rate is practically equal to that of other publication types.

Drawing the Ideal World and Real World: A Study of Lesbian, Labour and Social Inclusion

Full Text Available In this paper, we analyze the experience of lesbian women in Juiz de Fora on the scope of work, society and the individual, from drawings made by them. Discussed the experience of sexuality and lesbophobia as aspects present in their lives and at work, considering that fall into a heteronormative context. So, we conducted a qualitative study with the preparation of drawings and interviews that allowed the construction of categories: being lesbian, inclusion and social integration, personal and professional development, and real world and the ideal world. These drawings are shown as a rich and interesting technique to provide access to their subjective and symbolic dimensions as to their social and work experiences. Finally, we advocate a reflective and humanistic stance both in society and in organizations about the socially constructed and valued patterns that can marginalize or stigmatize those fleeing them.

Full Text Available Abstract Background The highest Hepatitis C Virus (HCV prevalence in the world occurs in Egypt. Several studies from different parts of the world have found that 13% to 33% of patients with chronic HCV have associated diabetes, mostly type II Diabetes Mellitus (DM. In Egypt the prevalence of DM is 25.4% among HCV patients. Therefore, it is important to identify the magnitude of the problem of diabetes in order to optimize the treatment of chronic hepatitis C. Methods The objective of this case-control study was to evaluate the prevalence of DM and other extrahepatic (EH manifestations among patients with different HCV morbidity stages including asymptomatic, chronic hepatic and cirrhotic patients. In this study, 289 HCV patients older than 18 were selected as cases. Also, 289 healthy controls were included. Laboratory investigations including Liver Function tests (LFT and blood glucose level were done. Also serological assays including cryoglobulin profile, rheumatoid factor, antinuclear antibody, HCV-PCR were performed. Results Out of 289 HCV cases, 40 (13.84% were diabetic. Out of 289 healthy controls, 12 (4.15% were diabetic. It was found that the diabetic HCV group mean age was [48.1 (± 9.2]. Males and urbanians represented 72.5% and 85% respectively. Lower level of education was manifested in 52.5% and 87.5% were married. In the nondiabetic HCV group mean age was [40.7 (± 10.4]. Males and urbanians represented 71.5% and 655% respectively. secondary and higher level of education was attained in 55.4% and 76.7% were married. Comparing between the diabetic HCV group and the non diabetic HCV group, age, residence and alcohol drinking were the only significant factors affecting the incidence of diabetes between the two groups. There was no significant difference regarding sonar findings although cirrhosis was more prevalent among diabetic HCV cases and the fibrosis score was higher in diabetic HCV patients than among the non diabetic HCV cases

On World Religion Adherence Distribution Evolution

Science.gov (United States)

Ausloos, Marcel; Petroni, Filippo

Religious adherence can be considered as a degree of freedom, in a statistical physics sense, for a human agent belonging to a population. The distribution, performance and life time of religions can thus be studied having in mind heterogeneous interacting agent modeling. We present a comprehensive analysis of 58 so-called religions (to be better defined in the main text) as measured through their number of adherents evolutions, between 1900 and 2000, - data taken from the World Christian Trends (Barrett and Johnson, "World Christian Trends AD 30 - AD 2200: Interpreting the Annual Christian Megacensus", William Carey Library, 2001): 40 are considered to be "presently growing" cases, including 11 turn overs in the twentieth century; 18 are "presently decaying", among which 12 are found to have had a recent maximum, in the nineteenth or the twentieth century. The Avrami-Kolmogorov differential equation which usually describes solid state transformations, like crystal growth, is used in each case in order to obtain the preferential attachment parameter introduced previously (Europhys Lett 77:38002, 2007). It is not often found close to unity, though often corresponding to a smooth evolution. However large values suggest the occurrence of extreme cases which we conjecture are controlled by so-called external fields. A few cases indicate the likeliness of a detachment process. We discuss a few growing and decaying religions, and illustrate various fits. Some cases seem to indicate the lack of reliability of the data, but others some marked departure from Avrami law. Whence the Avrami evolution equation might be surely improved, in particular, and somewhat obviously, for the decaying religion cases. We point out two major difficulties in such an analysis: (1) the "precise" original time of apparition of a religion, (2) the time at which there is a maximum number of adherents, both information being necessary for integrating reliably any evolution equation.

Experimental quantum annealing: case study involving the graph isomorphism problem.

Zick, Kenneth M; Shehab, Omar; French, Matthew

2015-06-08

Quantum annealing is a proposed combinatorial optimization technique meant to exploit quantum mechanical effects such as tunneling and entanglement. Real-world quantum annealing-based solvers require a combination of annealing and classical pre- and post-processing; at this early stage, little is known about how to partition and optimize the processing. This article presents an experimental case study of quantum annealing and some of the factors involved in real-world solvers, using a 504-qubit D-Wave Two machine and the graph isomorphism problem. To illustrate the role of classical pre-processing, a compact Hamiltonian is presented that enables a reduced Ising model for each problem instance. On random N-vertex graphs, the median number of variables is reduced from N(2) to fewer than N log2 N and solvable graph sizes increase from N = 5 to N = 13. Additionally, error correction via classical post-processing majority voting is evaluated. While the solution times are not competitive with classical approaches to graph isomorphism, the enhanced solver ultimately classified correctly every problem that was mapped to the processor and demonstrated clear advantages over the baseline approach. The results shed some light on the nature of real-world quantum annealing and the associated hybrid classical-quantum solvers.

2012-05-01

The objectives of this article were to study the reported prevalence of haemophilia B (HB) on a country-by-country basis and to analyse whether the prevalence of HB varied by national economy. The prevalence of HB is the proportion of diagnosed, reported cases of HB in a population at a specific point of time. We collected data on the HB prevalence for 105 countries from the World Federation of Hemophilia annual global surveys. Our results showed that the HB prevalence varied considerably among countries, even among the wealthiest of countries. The HB prevalence (per 100 000 males) for the highest income countries was 2.69 ± 1.61 (mean ± SD), whereas the prevalence for the rest of the world was 1.20 ± 1.33 (mean ± SD). Ireland had the highest reported HB prevalence of 8.07 per 100 000 males. There was a strong trend of increasing HB prevalence (per 100 000 males) over time. Prevalence data reported from the WFH compared well with prevalence data from the literature. The WFH annual global surveys have some limitations, but they are the best available source of worldwide haemophilia data. Prevalence data are extremely valuable information for the planning efforts of national healthcare agencies in setting priorities and allocating resources for the treatment of HB. © 2011 Blackwell Publishing Ltd.

The world health organization multicountry survey on maternal and newborn health: study protocol

Directory of Open Access Journals (Sweden)

2011-10-01

Full Text Available Abstract Background Effective interventions to reduce mortality and morbidity in maternal and newborn health already exist. Information about quality and performance of care and the use of critical interventions are useful for shaping improvements in health care and strengthening the contribution of health systems towards the Millennium Development Goals 4 and 5. The near-miss concept and the criterion-based clinical audit are proposed as useful approaches for obtaining such information in maternal and newborn health care. This paper presents the methods of the World Health Organization Multicountry Study in Maternal and Newborn Health. The main objectives of this study are to determine the prevalence of maternal near-miss cases in a worldwide network of health facilities, evaluate the quality of care using the maternal near-miss concept and the criterion-based clinical audit, and develop the near-miss concept in neonatal health. Methods/Design This is a large cross-sectional study being implemented in a worldwide network of health facilities. A total of 370 health facilities from 29 countries will take part in this study and produce nearly 275,000 observations. All women giving birth, all maternal near-miss cases regardless of the gestational age and delivery status and all maternal deaths during the study period comprise the study population. In each health facility, medical records of all eligible women will be reviewed during a data collection period that ranges from two to three months according to the annual number of deliveries. Discussion Implementing the systematic identification of near-miss cases, mapping the use of critical evidence-based interventions and analysing the corresponding indicators are just the initial steps for using the maternal near-miss concept as a tool to improve maternal and newborn health. The findings of projects using approaches similar to those described in this manuscript will be a good starter for a more

Agalmatophilia. The love for the statues in the Ancient World: the Cnidian Aphrodite and the case of Pygmalion

Directory of Open Access Journals (Sweden)

Giulia Ferrari

2013-02-01

Full Text Available The sexual attraction to statues, also known as 'agalmatophilia', seems to be prevalent in the Ancient World: the case of the Cnidian Aphrodite is of particular interest. According to multiples ancient sources, this statue, made by Praxiteles was able to arouse the erotic desire in the observer. However, this case must be contextualised in the ancient Greece, where different powers were ascribed to the divinities and great importance was given to Mimesis. The literary case of Pygmalion, recorded by Ovid in the Metamorphoses, plays a key role in this context as well. Here, the power of poetry allows the achievement of a happy end through the transformation of the statue into a real woman. Hereof we underline the analogies between the sculpture moulded by Pygmalion and the doll, which allow us to perceive in this myth a sort of conceptual bridge towards a contemporary form of agalmatophilia, the one that employs sex dolls.

Vision is the ability of seeing with a definite understanding of features, color and contrast, and to distinguish between objects visually. In the year 1999, the World Health Organization (WHO) and the International Agency for the Prevention of Blindness formulated a worldwide project for the eradication of preventable loss of sight with the subject of "Vision 2020: the Right to Sight". This global program aims to eradicate preventable loss of sight by the year 2020. This study was conducted to determine the main causes of low vision in Saudi Arabia and also to assess their visual improvement after using low vision aids (LVD).The study is a retrospective study and was conducted in low vision clinic at Eye World Medical Complex in Riyadh, Saudi Arabia. The file medical record of 280 patients attending low vision clinics from February 2008 to June 2010 was included. A data sheet was filled which include: age, gender, cause of low vision, unassisted visual acuity for long distances and short distances, low vision devices needed for long distances and short distances that provides best visual acuity. The result shows that the main cause of low vision was Optic atrophy (28.9%). Retinitis pigmentosa was the second cause of low vision, accounting for 73 patients (26%) followed by Diabetic retinopathy and Macular degeneration with 44 patients (15.7%) and 16 patients (5.7%) respectively. Inter family marriage could be one of the main causes of low vision. Public awareness should be embarked on for enlightenment on ocular diseases result in consanguineous marriage. Also, it is an important issue to start establishing low vision clinics in order to improve the situation.

There is no doubt that real-world evidence studies have the potential to improve and accelerate the development and delivery of safe and cost-effective innovative medicines to patients as well as influence the way we approach health and health care. Real-world evidence studies are a great challenge in terms of development and conduct, so there should be a good collaboration between the study team and clinical sites at all times, resulting eventually in timely and efficient enrollment. Engaging the sites and key external experts as early as possible during feasibility and routine visits, as well as highlighting the science rationale behind AstraZeneca's portfolio at investigator meetings and during medical science liaison (MSL) interactions, can create a positive impact on physician perception of a particular study and prioritization of patient recruitment in such studies. Therefore, we would like to underline the important role of MSLs in the risk-based monitoring setting of real-world evidence studies, with special attention to the studies with complicated patient profiles, tough timelines, and/or seasonal factors. This approach will be used further for other real world evidence projects of AstraZeneca Russia MC to ensure timelines and budget deliverables are met for the generation of high-quality evidence and eventually better health care for all of us.

Case Study: Iran, Islam, the NPT, and the Bomb

Energy Technology Data Exchange (ETDEWEB)

Saunders, E .

2011-04-01

The goals of this case study are: (1) To examine the correlation between Iran's nuclear program and clerical statements; (2) To evaluate the importance of these statements; (3) To understand the relationship between policy and fatwas (Islamic decrees); (4) To address the issue of a 'nuclear fatwa'; and (5) To examine how, if at all, Sharia (Islamic law) has influenced Iran's actions or inactions with respect to the Non-Proliferation Treaty (NPT), the International Atomic Energy Agency (IAEA), and Iran's adherence to its IAEA Safeguards Agreements and the Additional Protocol. The Islamic Republic of Iran (hereinafter Iran) is one of two theocracies in the world, the second being Vatican City. Iran's government derives its constitutional, moral, and political legitimacy from Islam. As a result of this theocratic culture, rules are set and interpreted with a much different calibrator than that of the Western world. Islam affects all aspects of Iranian life. This is further complicated by the fact that Islam is not a nationalistic faith, in that many people all over the world believe in and adhere to Islamic principles. As a result, a political system that derives much of its fervor from being nationalistic is caught between two worlds, one within the land boundaries of Iran and the other within a faith that transcends boundaries. Thus, any understanding of Islamic law must first be understood within this delicate balance of nationalism and transcendence. Iran has found itself on the international stage concerning its nuclear program. Because Iran is a theocratic state, it is imperative to examine its political moves, speeches, rights, and obligations through the lens of Islam. This study will examine how Islam plays a role in Iran's dealing with the International Atomic Energy Agency (IAEA), its understanding of the Nuclear Non-Proliferation Treaty (NPT), including parties obligations under Safeguards Agreements and the Additional

2011-07-01

Full Text Available This paper presents a case study of the design issues facing a large multi-format virtual conference. The conference took place twice in two different years, each time using an avatar-based 3D world with spatialized audio including keynote, poster and social sessions. Between year 1 and 2, major adjustments were made to the architecture and design of the space, leading to improvement in the nature of interaction between the participants. While virtual meetings will likely never supplant the effectiveness of face-to-face meetings, this paper seeks to outline a few design principles learned from this experience, which can be applied generally to make computer mediated collaboration more effective.

Full Text Available Using the two case studies presented in this work, this article aims to evaluate identification technology used in the Brazilian cattle market. Although Brazil possesses large companies in this sector (one of which is the largest exporter of meat in the world some of them have yet to implement information technology (IT for cattle identification purposes. Radio Frequency Identification (RFID is an IT that identifies cattle using electronic ear tags. This particular form of technology is especially accurate and dependable as it can be used to trace a product from the origin of conception to the consumer. This paper utilizes a qualitative approach – two case studies – which were created with the application of a questionnaire (open and closed questions. Using RFID for internal control purposes only, each of the sample companies has limited use of the technology. Instead, these companies use barcode systems to trace and identify cattle and to send important information to their supply chain partners.

Science.gov (United States)

Mahoney, James; Barrenechea, Rodrigo

2017-12-19

In this paper, we develop a set-theoretic and possible worlds approach to counterfactual analysis in case-study explanation. Using this approach, we first consider four kinds of counterfactuals: necessary condition counterfactuals, SUIN condition counterfactuals, sufficient condition counterfactuals, and INUS condition counterfactuals. We explore the distinctive causal claims entailed in each, and conclude that necessary condition and SUIN condition counterfactuals are the most useful types for hypothesis assessment in case-study research. We then turn attention to the development of a rigorous understanding of the 'minimal-rewrite' rule, linking this rule to insights from set theory about the relative importance of necessary conditions. We show why, logically speaking, a comparative analysis of two necessary condition counterfactuals will tend to favour small events and contingent happenings. A third section then presents new tools for specifying the level of generality of the events in a counterfactual. We show why and how the goals of formulating empirically important versus empirically plausible counterfactuals stand in tension with one another. Finally, we use our framework to link counterfactual analysis to causal sequences, which in turn provides advantages for conducting counterfactual projections. © London School of Economics and Political Science 2017.

Introduction: Researching online worlds: challenging media and communication studies

Directory of Open Access Journals (Sweden)

Kjetil Sandvik

2009-12-01

Full Text Available Digital media and network communication technology have not changed this setup, but rather have opened the possibility for encountering and experiencing additional types of worlds and performing additional types of spatial practices. Being situated online and being globally networked with the possibility of both synchronous and asynchronous communication, digitally mediated worlds provide possible interactions between users which are radically more independent of time and place than the ones facilitated by older media. From this perspective, the concept of online worlds both challenges and broadens our understanding of how media shape the world and how the media technology creates new social structures.

1978-01-01

The extent of the threat to the US helicopter industry posed by a determined effort by foreign manufacturers, European companies in particular, to supply their own domestic markets and also to penetrate export markets, including the USA is assessed. Available data on US and world markets for civil and military uses are collated and presented in both graphic and tabular form showing the past history of production and markets and, where forecasts are available, anticipated future trends. The data are discussed on an item-by-item basis and inferences are drawn in as much depth as appears justified.

1998-01-01

World spinors are objects that transform w.r.t. double covering group Diff(4, R) of the Group of General Coordinate Transformations. The basic mathematical results and the corresponding physical interpretation concerning these, infinite-dimensional, spinorial representations are reviewed. The role of groups Diff(4, R), GA(4, R), GL(4, R), SL(4, R), SO(3,1) and the corresponding covering groups is pointed out. New results on the infinite dimensionality of spinorial representations, explicit construction of the SL(4, R) representations in the basis of finite-dimensional non-unitary SL(2, C) representations, SL(4, R) representation regrouping of tonsorial and spinorial fields of an arbitrary spin Lagrangian field theory, as well as its SL(5, R) generalization in the case of infinite-component world spinor and tensor field theories are presented.

Case Studies of Community-Academic Partnerships Established Using the Give-Get Grid Model.

Science.gov (United States)

Behringer, Bruce; Southerland, Jodi L; Plummer, Robert M

2017-11-01

While partnerships for health delivery and improvement are frequently described by their structure, goals, and plans, less attention is paid to the interactive relationships among partners or for larger stakeholder groups' coalition memberships. The Give-Get Grid group process tool can be used to assess each stakeholders' expected benefits ("gets") and contributions ("gives") needed to establish and maintain long-term, mutually advantageous community-academic partnerships. This article describes three case study experiences using the Give-Get Grid in real-world context to understand and generate ideas to address contemporary health promotion opportunities among a variety of stakeholders. The case studies address three distinct community health promotion opportunities: prevention of school-based adolescent obesity disparities, higher education health professions training programs in rural community-based settings, and methods for engaging community coalitions in state Comprehensive Cancer Control Programs. The case studies demonstrate the Give-Get Grid's utility in both planning and evaluating partnerships and documenting key elements for progress in health promotion initiatives built on long-term community-academic relationships. Steps are explained with practical lessons learned in using the Grid.

Bianchi type II brane-world cosmologies (U≥0)

International Nuclear Information System (INIS)

Hoogen, R.J. van den; Ibanez, J.

2003-01-01

The asymptotic properties of the Bianchi type II cosmological model in the brane-world scenario are investigated. The matter content is assumed to be a combination of a perfect fluid and a minimally coupled scalar field that is restricted to the brane. The isotropic brane-world solution is determined to represent the initial singularity in all brane-world cosmologies. Additionally, it is shown that it is the kinetic energy of the scalar field which dominates the initial dynamics in these brane-world cosmologies. It is important to note that the dynamics of these brane-world cosmologies is not necessarily asymptotic to general relativistic cosmologies to the future in the case of a zero four-dimensional cosmological constant

Radiochemistry in the world: a biblio-metric study (1989-1998)

International Nuclear Information System (INIS)

Guillaumont, R.; Madic, Ch.; Pichot, Ch.; Rousseau-Hans, F.

2002-01-01

The study analyzes the world literature in the field of radiochemistry. It tries to represent the radiochemistry, through the development of its sub-fields in the different parts of the world and through the international collaboration patterns. Most data come from the INIS (International Nuclear Information System) database operated by the International Atomic Energy Agency (IAEA) and cover the 1989-1998 era. Less rich countries publish proportionally more in fundamental radiochemistry whereas high developed countries invest more in nuclear medicine. Another aspect of the radiochemistry is approached with the study of scientific national and international journals which publish articles in this field. English remains the most important language used in the fundamental fields of radiochemistry while national languages, such as russian, japanese and chinese, keep a certain importance in applied sciences like earth sciences, waste management and nuclear medicine.

Blended learning in health education: three case studies.

Science.gov (United States)

de Jong, Nynke; Savin-Baden, Maggi; Cunningham, Anne Marie; Verstegen, Daniëlle M L

2014-09-01

Blended learning in which online education is combined with face-to-face education is especially useful for (future) health care professionals who need to keep up-to-date. Blended learning can make learning more efficient, for instance by removing barriers of time and distance. In the past distance-based learning activities have often been associated with traditional delivery-based methods, individual learning and limited contact. The central question in this paper is: can blended learning be active and collaborative? Three cases of blended, active and collaborative learning are presented. In case 1 a virtual classroom is used to realize online problem-based learning (PBL). In case 2 PBL cases are presented in Second Life, a 3D immersive virtual world. In case 3 discussion forums, blogs and wikis were used. In all cases face-to-face meetings were also organized. Evaluation results of the three cases clearly show that active, collaborative learning at a distance is possible. Blended learning enables the use of novel instructional methods and student-centred education. The three cases employ different educational methods, thus illustrating diverse possibilities and a variety of learning activities in blended learning. Interaction and communication rules, the role of the teacher, careful selection of collaboration tools and technical preparation should be considered when designing and implementing blended learning.

Final report on case studies

DEFF Research Database (Denmark)

Ljungberg, Daniel; McKelvey, Maureen; Lassen, Astrid Heidemann

2012-01-01

Case study as a research design means investigating a single or multiple instance(s) or setting(s) (i.e. a case) and its entire context to explain a phenomenon and its processes. This is achieved through detailed understanding, usually comprised of multiple sources of information. In this way, case...... studies attempt to provide as a complete an understanding of a (complex) phenomenon as possible. Within the AEGIS project, survey and case study research are complementary. They are complementary in the sense that the former can provide more generalizable evidence on a phenomenon in terms of cross......-sectional data, while the latter can provide more in-depth (qualitative) understanding on specific issues. In systematically examining the case studies, however, this report goes beyond a typical single case study. Here we provide a synthesis of 86 case studies.

In academic education systems and in the business world under the term ‘business communication’ various definitions exist, which are applied across the fields of academic studies and in the business world. After the comparison of definitions of ‘business communication’, we demonstrate the various layers of business communication in the contemporary corporate world based upon a model of the corporate world and these cases using examples of companies implementing ‘business communication’ into their corporate structure.

Development of a tissue engineered heart valve for pediatrics: a case study in bioengineering ethics.

Science.gov (United States)

Merryman, W David

2008-03-01

The following hypothetical case study was developed for bioengineering students and is concerned with choosing between two devices used for development of a pediatric tissue engineered heart valve (TEHV). This case is intended to elicit assessment of the devices, possible future outcomes, and ramifications of the decision making. It is framed in light of two predominant ethical theories: utilitarianism and rights of persons. After the case was presented to bioengineering graduate students, they voted on which device should be released. The results revealed that these bioengineering students preferred the more reliable (and substantially more expensive) design, though this choice precludes the majority of the world from having access to this technology. This case is intended to examine and explore where the balance lies between design, cost, and adequate distribution of biomedical devices.

To determine the incidence, severity and nature of injuries sustained during the Rugby World Cup (RWC) 2015 together with the inciting events leading to the injuries. A prospective, whole population study. 639 international rugby players representing 20 countries. The study protocol followed the definitions and procedures recommended in the consensus statement for epidemiological studies in rugby union; output measures included players' age (years), stature (cm), body mass (kg) and playing position, and the group-level incidence (injuries/1000 player-hours), mean and median severity (days-absence), location (%), type (%) and inciting event (%) for match and training injuries. Incidence of injury was 90.1 match injuries/1000 player-match-hours (backs: 100.4; forwards: 81.1) and 1.0 training injuries/1000 player-training-hours (backs: 0.9; forwards: 1.2). The mean severity of injuries was 29.8 days-absence (backs: 30.4; forwards: 29.1) during matches and 14.4 days-absence (backs: 6.3; forwards: 19.8) during training. During matches, head/face (22.0%), knee (16.2%), muscle-strain (23.1%) and ligament-sprain (23.1%) and, during training, lower limb (80.0%) and muscle-strain (60.0%) injuries were the most common locations and types of injury. Being-tackled (24.7%) was the most common inciting event for injury during matches and rugby-skills-contact activities (70.0%) the most common during training. While the incidence, nature and inciting events associated with match injuries at RWC 2015 were similar to those reported previously for RWCs 2007 and 2011, there were increasing trends in the mean severity and total days-absence through injury.

World uranium supply and demand

International Nuclear Information System (INIS)

Patterson, J.A.

1980-01-01

The role of nuclear energy is under increasing scrutiny and uncertainty. None the less, there will be an increasing need for expansion of uranium supply to fuel committed reactors. Longer-term demand projections are very uncertain. Improved knowledge of the extent of world resources and their availability and economics is needed to support planning for reactor development, especially for breeder reactors, and for fuel-cycle development, especially enrichment, and reprocessing and recycle of uranium and plutonium. Efforts to date to estimate world uranium resources have been very useful but have largely reflected the state of available knowledge for the lower cost resources in regions that have received considerable exploration efforts. The IUREP evaluation of world resources provides an initial speculative estimate of world resources, including areas not previously appraised. Projections of long-range supply from the estimated resources suggest that the high-growth nuclear cases using once-through cycle may not be supportable for very long. However, additional effort is needed to appraise and report more completely and consistently on world resources, the production levels attainable from these resources, and the economic and price characteristics of such production.

Possible limitations to SSPS use due to distribution of world population and world energy consumption centers

Energy Technology Data Exchange (ETDEWEB)

Claverie, M.J.; Dupas, A.P.

1980-09-01

Satellite solar power stations, as envisioned now, would be very large energy systems from the point of view of power output (about 5 GW) and of land requirements (more than 400 sq km for a rectenna and the associated exclusion area). These size constraints could lead to limitations in the use of SSPS in significant parts of the world, due to three main incompatibilities: too high population density, insufficient density of electrical demand, and obligation for a single power station to provide less than about 20% of the total electrical demand in a given geographical zone to assure reliability. The extent of these three possible limitations was assessed, using a future world energy model developed previously. The rationale behind this model is to divide the world into 10 deg latitude by 10 deg longitude zones, in which future electrical demands (in 2000 and 2020/2025) are computed according to energetical previsions of the Case Western Reserve University (CWRU) and of the World Energy Conference (WEC). The results are world wide maps of electrical demand densities in 2000 and 2020/2025.

Contraceptive social marketing in the third world: a case of multiple transfer.

Science.gov (United States)

Luthra, R

1991-01-01

A researcher conducted a case study of the Family Planning Social Marketing Project (FPSMP) in Bangladesh between 1974-1987 to point out the irreducible qualitative differences between the commercial and social contexts and between the developed and developing world. The research consisted of interviews with chief personnel of the technical assistance contractor Population Services International (PSI), project documentation, a review of marketing principles and methods, and summary reports on contraceptive social marketing projects in various countries. FPSMP, a vertical marketing organization, marketed 3 condom brands, 2 oral contraceptive brands, and 1 vaginal foam tablet. At least 70% of the advertising budget was allocated for conventional media (television [TV], radio, and newspapers), even though the poor and illiterate target population did not own a radio or TV and could not read a newspaper. In fact, conventional media were basically accessible to the urban elite. A PSI leader defended the use of conventional media because opinion leaders (urban elite) exert considerable influence on the population so they must receive the family planning messages in order to support family planning. Yet this assumption had not been tested, but was based on the experience of technical assistance contractors from previous projects in developing countries. Moreover, FPSMP based acceptability of message content on the elite's definition and not on the definition of the target group. Its information strategy included emphasis on the sales indicator and the creation of positive product associations while downplaying information about side effects and contraindications. This indicated that FPSMP did not consider client health and well being as important. Another issue was the need to satisfy USAID and the government. More research on other social marketing projects is needed.

Prayer Healing: A Case Study Research Protocol.

Science.gov (United States)

Kruijthoff, Dirk J; van der Kooi, Cornelis; Glas, Gerrit; Abma, Tineke A

2017-01-01

Context • Prayer healing is a common practice in many religious communities around the world. Even in the highly secularized Dutch society, cases of prayer healing are occasionally reported in the media, often generating public attention. There is an ongoing debate regarding whether such miraculous cures do actually occur and how to interpret them. Objective • The aim of the article was to present a research protocol for the investigation of reported cases of remarkable and/or unexplained healing after prayer. Design • The research team developed a method to perform a retrospective, case-based study of prayer healing. Reported prayer healings can be investigated systematically in accordance with a step-by-step methodology. The focus is on understanding the healing by studying it from multiple perspectives, using both medical judgment and patients' narratives collected by qualitative methods Setting • The study occurred at Vrije Universiteit (VU) and VU Medical Center (Amsterdam, Netherlands) as well as the general medical practice of the first author. Participants • Potential participants could be any individuals in the Netherlands or neighboring countries who claim to have been healed through prayer. The reports of healing came from multiple sources, including the research team's medical practices and their direct vicinities, newspaper articles, prayer healers, and medical colleagues. Outcome Measures • Medical data were obtained before and after prayer. Subsequently, a member of a research team and of a medical assessment committee made a standardized judgment that evaluated whether a cure was clinically remarkable or scientifically unexplained. The participants' experiences and insider perspectives were studied, using in-depth interviews in accordance with a qualitative research methodology, to gain insight into the perceptions and explanations of the cures that were offered by participants and by the members of the medical assessment committee.

This article presents a pilot study of the use of two new tangible interfaces and virtual worlds for teaching geometry in a secondary school. The first tangible device allows the user to control a virtual object in six degrees of freedom. The second tangible device is used to modify virtual objects, changing attributes such as position, size, rotation and color. A pilot study on using these devices was carried out at the "Florida Secundaria" high school. A virtual world was built where students used the tangible interfaces to manipulate geometrical figures in order to learn different geometrical concepts. The pilot experiment results suggest that the use of tangible interfaces and virtual worlds allowed a more meaningful learning (concepts learnt were more durable).

World Regional Studies as a Research Framework and Academic Discipline

2016-01-01

Full Text Available Dynamic development of international processes at the regional level, various trajectories of regionalization in Europe, Asia, Latin America and other parts of the world created a complex and multidimensional picture of the contemporary international relations. However Social Sciences and IR retained a distinct eurocentrism. This eurocentrism only partly meant that students of IR did not take into account non-European or non-Western realities. Thus, a German Scholar J. Vullers from German Institute of Global and Area Studies analyzing in 2014 three leading International Relations journals (International Organization, World Politics, European Journal of International Relations diagnosed a serious geographic imbalance in the international studies, which meant a very limited number of articles based on the nonWestern empirical data.Even with such geographic imbalance in IR studies more important for preserving eurocentrism there was the absence of non-Western IR theories or IR theories originating from non-Western political context. The collective monograph edited by Barry Buzan and Amitav Acharya focused exactly on this problem. The title of the book was provocatively asking why there is no non-Western IR theory. Thus, the book in question provoked a lively academic debate on the topic. Russia was not covered in this book. Therefore, this very fact gives one some reasons to reflect on how Russian research in the field may face a double challenge of a changing international environment and an inappropriate level of its intellectual assessment. Against this background this article analyzes World Regional Studies, a research framework and discipline, which is rapidly developing in Russia and may to some extent contribute to a more correct understanding of the international processes.

Case-non case studies belongs to the methods assessing drug safety by analyzing the disproportionality of notifications of adverse drug reactions in pharmacovigilance databases. Used for the first time in the 1980s, the last few decades have seen a significant increase in the use of this design. The principle of the case-non case study is to compare drug exposure in cases of a studied adverse reaction with that of cases of other reported adverse reactions and called "non cases". Results are presented in the form of a reporting odds ratio (ROR), the interpretation of which makes it possible to identify drug safety signals. This article describes the principle of the case-non case study, the method of calculating the ROR and its confidence interval, the different modalities of analysis and how to interpret its results with regard to the advantages and limitations of this design.

Boulos, Maged N Kamel; Hetherington, Lee; Wheeler, Steve

2007-12-01

This hybrid review-case study introduces three-dimensional (3-D) virtual worlds and their educational potential to medical/health librarians and educators. Second life (http://secondlife.com/) is perhaps the most popular virtual world platform in use today, with an emphasis on social interaction. We describe some medical and health education examples from Second Life, including Second Life Medical and Consumer Health Libraries (Healthinfo Island-funded by a grant from the US National Library of Medicine), and VNEC (Virtual Neurological Education Centre-developed at the University of Plymouth, UK), which we present as two detailed 'case studies'. The pedagogical potentials of Second Life are then discussed, as well as some issues and challenges related to the use of virtual worlds. We have also compiled an up-to-date resource page (http://healthcybermap.org/sl.htm), with additional online material and pointers to support and extend this study.

Full Text Available The authors set out to examine the impact of Psychoanalysis in Nigeria. In doing this they selected a significant stakeholder, who trained in Germany and returned to Nigeria as a case study. Examining the activities as he set out to indigenize psychotherapy in Nigeria, it was found that psychoanalytic thinking helped in the psychodynamic observations on the frequent somatic complaints of psychological origin which helped to make treatment possible. Family therapy based on psychoanalysis was modeled to treat patients classified as traditional, mixed and westernized. Dream analysis and hypnosis were also used for treatment in Nigeria with good results. Finally the harmony restoration theory was put forward whereby the African is healthy when he is at peace with his world of relationship (cosmos comprising endocosmos – mind body relationship, mesocosmos relationship with significant others and exocosmos relationship with spirits, ancestors, deities, gods, God. He/she is sick when there is a distortion in the person’s world of relationship. Treatment is restoration of harmony. In every one there is a yearning to reach out to others (cosmic expansion drive and an inclination to be interested in the self (cosmic reduction drive at the various levels of the cosmos. Eight personality types were worked out of the combination of expansion and reduction drives. The conclusion was that psychoanalysis has come to stay in Nigeria.

Heffner, G.; Maurer, L.; Sarkar, A.; Wang, X. [The World Bank, 1818 H Street, NW, Washington DC 20433 (United States)

2010-04-15

This paper describes the World Bank's technical assistance and lending efforts in support of developing countries facing power shortages. The paper reviews the World Bank's experience in helping governments to mitigate power shortages in Africa, South Asia, East Asia, and Latin America regions. The paper stresses the need to consider each power ''crunch'' on an individual basis, and describes the process used in diagnosing a shortage situation and prescribing mitigation strategies. Several brief case studies are presented, including Botswana, Brazil, Uganda, and South Africa. The political and customer-centric dimensions of power shortage mitigation are briefly described, with suggestions for minimizing the socio-economic impacts of power shortages on the urban and rural poors. The paper concludes that an integrated supply-demand portfolio approach works best, and within the portfolio a mix of market-based rationing, emergency mobilization of customer-owned generation, interruptible rates, load control, and energy efficient lighting should be sought. Although the best formulation will vary according to market structure, demand composition, and nature of the crisis, World Bank practitioners have found one program that works almost everywhere to produce fast and effective results - mass market Compact Fluorescent Lamp (CFL) replacement programs.

Full Text Available This article aims to continue the study by Kilimnik et al. (2011 - as in previous studies conducted on the subject by Kilimnik, Correa Oliveira (2009a and Kilimnik and Correa (2009b - on professional skills and managers who made a career transition from corporations to the academic field. Using these authors’ original proposal five years after their research, we seek to investigate any changes in their teaching skills as well as to identify didactic and pedagogical strategies used. Adopting the qualitative approach as done previously, this research features a longitudinal cohort study and it involved conducting 25 semi-structured interviews in depth with individuals who participated in the previous empirical survey. The content analysis of interviews was carried out with the help of the QDA Miner software. The results confirm a significant part of the competencies identified in the previous survey. It was also verified that the respondents seek to transfer the experience of the corporate world to the academia using educational techniques such as case studies and dynamics. According to the respondents themselves, work experience, despite being one of the strengths they brought from the corporate world, is not enough if not associated with theory, generating learning.

Full Text Available Lesson Study as a growing interest in the education world has attracted educators, experts, and professionals in the area to make use of it in improving the lessons—it also happens in Indonesia. Originally applied in the teaching of mathematics in Japan, now it turns to be used in other fields, and English is one of them. This paper highlights the guideline on Lesson Study and pictures its application in a private senior high school in Malang, East Java, Indonesia. The adaptation of Lesson Study is interesting since Japan and Indonesia have different cultural background. How Lesson Study is usually implemented in Japan and the US and how it is applied in Indonesia will be seen here. As this is a case study, it will only focus on a school and the result should not be used to generalize Lesson Study applications in Indonesia. Interview and observation were instruments used in this study. The interview was used to gain information on how Lesson Study was normally conducted and observation (and the researchers’ involvements was used to see the real implementation of Lesson Study. What happened during the implementation of Lesson Study and during the teaching and learning process become a great attention here.

New information on world uranium resource, production, supply and demand is introduced. Up to now, explored uranium resources at production cost < USD 40/kg U has 2523257 t uranium; production cost < USD 80/kg U has 5911514 t uranium; production cost < USD130/kg U has 11280488 t uranium; and cost range unassigned has 3102000 t uranium. At moment, the demand uranium of each year is about 67000 t U. After 2020, world uranium demand will rise well above 100000 t per annum with sharp revival of nuclear power plants. With three kinds of economic growth the cumulative requirement of the uranium in low demand case, middle demand case and high demand case from 2000 to 2050 is 3390000, 5394100 and 7577300 t respectively. In the world market uranium price rises from 20 years lowest 18.2 USD/kg U to 75.4 USD/kg U. In 2003, global uranium product is about 35385 t U, and 2004, global uranium product is about 40475 t U. In 2004's world uranium production underground mining, open pit, in situ, by product, and combination account for 39%, 27%, 19%, 11% and 4% respectively. (authors)

Objective After 9/11/2001, some Fire Department of New York (FDNY) workers had excessive lung function decline. We hypothesized that early serum matrix metalloproteinases (MMP) expression predicts World Trade Center-Lung Injury (WTC-LI) years later. Methods This is a nested case-control analysis of never-smoking male firefighters with normal pre-exposure Forced Expiratory Volume in one second (FEV1) who had serum drawn up to 155 days post 9/11/2001. Serum MMP-1, 2,3,7,8, 9, 12 and 13 were measured. Cases of WTC-LI (N = 70) were defined as having an FEV1 one standard deviation below the mean (FEV1≤77%) at subspecialty pulmonary evaluation (SPE) which was performed 32 months (IQR 21–53) post-9/11. Controls (N = 123) were randomly selected. We modeled MMP's ability as a predictor of cases status with logistic regression adjusted for time to blood draw, exposure intensity, weight gain and pre-9/11 FEV1. Results Each log-increase in MMP-3 and MMP-12 showed reduced odds of developing WTC-LI by 73% and 54% respectively. MMP-3 and MMP-12 consistently clustered together in cases, controls, and the cohort. Increasing time to blood draw significantly and independently increased the risk of WTC-LI. Conclusions Elevated serum levels of MMP-3 and MMP-12 reduce the risk of developing WTC-LI. At any level of MMP-3 or 12, increased time to blood draw is associated with a diminished protective effect. PMID:24146820

Observational studies, such as cohort and case-control studies, are valuable instruments in evidence-based medicine. Case-control studies, in particular, are becoming increasingly popular in the neurosurgical literature due to their low cost and relative ease of execution; however, no one has yet systematically assessed these types of studies for quality in methodology and reporting. The authors performed a literature search using PubMed/MEDLINE to identify all studies that explicitly identified themselves as "case-control" and were published in the JNS Publishing Group journals (Journal of Neurosurgery, Journal of Neurosurgery: Pediatrics, Journal of Neurosurgery: Spine, and Neurosurgical Focus) or Neurosurgery. Each paper was evaluated for 22 descriptive variables and then categorized as having either met or missed the basic definition of a case-control study. All studies that evaluated risk factors for a well-defined outcome were considered true case-control studies. The authors sought to identify key features or phrases that were or were not predictive of a true case-control study. Those papers that satisfied the definition were further evaluated using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist. The search detected 67 papers that met the inclusion criteria, of which 32 (48%) represented true case-control studies. The frequency of true case-control studies has not changed with time. Use of odds ratios (ORs) and logistic regression (LR) analysis were strong positive predictors of true case-control studies (for odds ratios, OR 15.33 and 95% CI 4.52-51.97; for logistic regression analysis, OR 8.77 and 95% CI 2.69-28.56). Conversely, negative predictors included focus on a procedure/intervention (OR 0.35, 95% CI 0.13-0.998) and use of the word "outcome" in the Results section (OR 0.23, 95% CI 0.082-0.65). After exclusion of nested case-control studies, the negative correlation between focus on a procedure

Full Text Available More than million foods have been made by people from all over the world in the latest years. People now try to create new cooks and make some creativity on it. Then, cooking which the field is culinary has become an art because it needs an artistic value to decorate the food, a good taste and proper technique in processing delicious food in order to make it a masterpiece. French culinary is as famous as the Eiffel tower in the heart of the country, Paris. Most of fine dining international restaurants apply the French menu and cooking. This article presents an overview about the French element in culinary world; starts from its history, kitchen organization, French menu spelling, and French cooking vocabulary. The discussion proceeds library research to compile the data. Later, the art of culinary is interesting to be learned because it contains the classical history of world civilization, in this case French civilization. The issue of cooking trend “nouvelle cuisine” was a masterpiece of one of the greatest chef in his time, Escoffier. French culinary is widely well-known in all over the world because of innovation, creativity, and proud. Those are spirits that we must learn.   

From Science to e-Science to Semantic e-Science: A Heliosphysics Case Study

Science.gov (United States)

Narock, Thomas; Fox, Peter

2011-01-01

The past few years have witnessed unparalleled efforts to make scientific data web accessible. The Semantic Web has proven invaluable in this effort; however, much of the literature is devoted to system design, ontology creation, and trials and tribulations of current technologies. In order to fully develop the nascent field of Semantic e-Science we must also evaluate systems in real-world settings. We describe a case study within the field of Heliophysics and provide a comparison of the evolutionary stages of data discovery, from manual to semantically enable. We describe the socio-technical implications of moving toward automated and intelligent data discovery. In doing so, we highlight how this process enhances what is currently being done manually in various scientific disciplines. Our case study illustrates that Semantic e-Science is more than just semantic search. The integration of search with web services, relational databases, and other cyberinfrastructure is a central tenet of our case study and one that we believe has applicability as a generalized research area within Semantic e-Science. This case study illustrates a specific example of the benefits, and limitations, of semantically replicating data discovery. We show examples of significant reductions in time and effort enable by Semantic e-Science; yet, we argue that a "complete" solution requires integrating semantic search with other research areas such as data provenance and web services.

How Symmetric Are Real-World Graphs? A Large-Scale Study

Directory of Open Access Journals (Sweden)

Fabian Ball

2018-01-01

Full Text Available The analysis of symmetry is a main principle in natural sciences, especially physics. For network sciences, for example, in social sciences, computer science and data science, only a few small-scale studies of the symmetry of complex real-world graphs exist. Graph symmetry is a topic rooted in mathematics and is not yet well-received and applied in practice. This article underlines the importance of analyzing symmetry by showing the existence of symmetry in real-world graphs. An analysis of over 1500 graph datasets from the meta-repository networkrepository.com is carried out and a normalized version of the “network redundancy” measure is presented. It quantifies graph symmetry in terms of the number of orbits of the symmetry group from zero (no symmetries to one (completely symmetric, and improves the recognition of asymmetric graphs. Over 70% of the analyzed graphs contain symmetries (i.e., graph automorphisms, independent of size and modularity. Therefore, we conclude that real-world graphs are likely to contain symmetries. This contribution is the first larger-scale study of symmetry in graphs and it shows the necessity of handling symmetry in data analysis: The existence of symmetries in graphs is the cause of two problems in graph clustering we are aware of, namely, the existence of multiple equivalent solutions with the same value of the clustering criterion and, secondly, the inability of all standard partition-comparison measures of cluster analysis to identify automorphic partitions as equivalent.

To evaluate real-world clinical and economic outcomes in patients with Clostridium difficile infection (CDI) treated with fidaxomicin. Retrospective case series. Academic medical center. A total of 61 patients with CDI who were treated with fidaxomicin monotherapy or combination therapy from September 2011 to December 2012. Data on demographics, infection characteristics, and clinical and economic outcomes were evaluated. Clinical cure was defined as resolution of diarrhea (less than or equal to three unformed stools for at least 2 consecutive days) maintained for the duration of therapy with no further requirement for CDI therapy and was achieved in 44 (72.1%) patients. Clinical cure was significantly higher for patients receiving fidaxomicin monotherapy compared with fidaxomicin combination therapy (25/29 [86.2%] patients vs 19/32 [59.4%] patients, p=0.04). Clinical cure was similar in patients with a first or prior CDI episode (65.5% vs 78.1%, p=0.27) and in patients with severe versus nonsevere disease (68.4% vs 73.8%, p=0.66). Recurrence occurred in 6 (13.6%) of the 44 patients who achieved clinical cure. Mortality attributable to CDI was 11.5%, and 30-day readmission rate was 4.9%. Median cost accrued during CDI was $19,483/patient. Our real-world experience with fidaxomicin significantly differs from the findings of phase III clinical trials. Fidaxomicin is also associated with substantial costs. Multicenter studies are needed to determine the optimal role of fidaxomicin in the treatment of CDI. © 2014 Pharmacotherapy Publications, Inc.

The Requel: Between the Remake and the Sequel. Jurassic World as a Case Study Analysis

Irene RAYA BRAVO

2017-06-01

Full Text Available In the audiovisual field, the expansion of the stories is, specifically, materialized through remakes, adaptations and franchises. In this context, the remakes or new versions are recurrent formulas because they recover familiar contents for audiences and, at the same time, they reinvent it in order to capture new generations’ attention. Nevertheless, the remake formula has been changing in the new millennium, adapting to new narrative trends. In recent years, because of the rise of intertextuality and the increasing value of nostalgia, many films have been produced halfway between the remake and the sequel, such as Star Wars. Episode VII: The Force Awakens or Terminator Genisys. In particular, the aim of this paper is to make a comparative analysis between Jurassic Park and Jurassic World because, although this last film extends the original discourse as a sequel, it also offers a reinterpretation of the first film.

Seven steps towards the classical world

Classical physics is about real objects, like apples falling from trees, whose motion is governed by Newtonian laws. In standard quantum mechanics only the wavefunctions or the results of measurements exist, and to answer the question of how the classical world can be part of the quantum world is a rather formidable task. However, this is not the case for Bohmian mechanics which, like classical mechanics, is a theory about real objects. In Bohmian terms, the problem of the classical limit becomes very simple: when do the Bohmian trajectories look Newtonian?

Energy Provider: Delivered Energy Efficiency: A global stock-taking based on case studies

NONE

2013-06-01

In 2011 the IEA and the Regulatory Assistance Project (RAP) took on a work programme focused on the role of energy providers in delivering energy efficiency to end-users. This work was part of the IEA’s contribution to the PEPDEE Task Group, which falls under the umbrella of the International Partnership on Energy Efficiency Cooperation (IPEEC). In addition to organizing regional dialogues between governments, regulators, and energy providers, the PEPDEE work stream conducted global stock-takings of regulatory mechanisms adopted by governments to obligate or encourage energy providers to delivery energy savings and the energy savings activities of energy providers. For its part the IEA conducted a global review of energy provider-delivered energy savings programmes. The IEA reached out to energy providers to identify the energy savings activities they engaged in. Some 250 energy saving activities were considered, and 41 detailed case studies spanning 18 countries were developed. Geographic balance was a major consideration, and much effort was expended identifying energy provider-delivered energy savings case studies from around the world. Taken together these case studies represent over USD 1 billion in annual spending, or about 8% of estimated energy provider spending on energy efficiency.

Game-Based Virtual Worlds as Decentralized Virtual Activity Systems

Science.gov (United States)

Scacchi, Walt

There is widespread interest in the development and use of decentralized systems and virtual world environments as possible new places for engaging in collaborative work activities. Similarly, there is widespread interest in stimulating new technological innovations that enable people to come together through social networking, file/media sharing, and networked multi-player computer game play. A decentralized virtual activity system (DVAS) is a networked computer supported work/play system whose elements and social activities can be both virtual and decentralized (Scacchi et al. 2008b). Massively multi-player online games (MMOGs) such as World of Warcraft and online virtual worlds such as Second Life are each popular examples of a DVAS. Furthermore, these systems are beginning to be used for research, deve-lopment, and education activities in different science, technology, and engineering domains (Bainbridge 2007, Bohannon et al. 2009; Rieber 2005; Scacchi and Adams 2007; Shaffer 2006), which are also of interest here. This chapter explores two case studies of DVASs developed at the University of California at Irvine that employ game-based virtual worlds to support collaborative work/play activities in different settings. The settings include those that model and simulate practical or imaginative physical worlds in different domains of science, technology, or engineering through alternative virtual worlds where players/workers engage in different kinds of quests or quest-like workflows (Jakobsson 2006).

Childhood pneumonia is among the leading infectious causes of mortality in children younger than 5 years of age globally. Streptococcus pneumoniae (pneumococcus) is the leading infectious cause of childhood bacterial pneumonia. The diagnosis of childhood pneumonia remains a critical epidemiological task for monitoring vaccine and treatment program effectiveness. The chest radiograph remains the most readily available and common imaging modality to assess childhood pneumonia. In 1997, the World Health Organization Radiology Working Group was established to provide a consensus method for the standardized definition for the interpretation of pediatric frontal chest radiographs, for use in bacterial vaccine efficacy trials in children. The definition was not designed for use in individual patient clinical management because of its emphasis on specificity at the expense of sensitivity. These definitions and endpoint conclusions were published in 2001 and an analysis of observer variation for these conclusions using a reference library of chest radiographs was published in 2005. In response to the technical needs identified through subsequent meetings, the World Health Organization Chest Radiography in Epidemiological Studies (CRES) project was initiated and is designed to be a continuation of the World Health Organization Radiology Working Group. The aims of the World Health Organization CRES project are to clarify the definitions used in the World Health Organization defined standardized interpretation of pediatric chest radiographs in bacterial vaccine impact and pneumonia epidemiological studies, reinforce the focus on reproducible chest radiograph readings, provide training and support with World Health Organization defined standardized interpretation of chest radiographs and develop guidelines and tools for investigators and site staff to assist in obtaining high-quality chest radiographs.

Childhood pneumonia is among the leading infectious causes of mortality in children younger than 5 years of age globally. Streptococcus pneumoniae (pneumococcus) is the leading infectious cause of childhood bacterial pneumonia. The diagnosis of childhood pneumonia remains a critical epidemiological task for monitoring vaccine and treatment program effectiveness. The chest radiograph remains the most readily available and common imaging modality to assess childhood pneumonia. In 1997, the World Health Organization Radiology Working Group was established to provide a consensus method for the standardized definition for the interpretation of pediatric frontal chest radiographs, for use in bacterial vaccine efficacy trials in children. The definition was not designed for use in individual patient clinical management because of its emphasis on specificity at the expense of sensitivity. These definitions and endpoint conclusions were published in 2001 and an analysis of observer variation for these conclusions using a reference library of chest radiographs was published in 2005.

The World Resources series is intended to meet the critical need for accessible, accurate information on some of the most pressing issues of our time. Wise management of natural resources and protection of the global environment are essential to achieve sustainable economic development and hence to alleviate poverty, improve the human condition, and preserve the biological systems on which all life depends. This volume has a special focus on sustainable development, in support of the upcoming 1992 United Nations Conference on Environment and Development (UNCED). Part 1 consists of four special chapters on sustainable development: an overview chapter and three case studies of what sustainable development might mean in industrial countries, low-income countries, and rapidly industrializing countries. Additional material pertinent to this topic is found throughout the volume. Part 2 continues the tradition of examining in each volume a particular region in more detail - in this case, an overview of the severe environmental and resource problems faced by Central Europe as that region makes a difficult transition to more democratic governments and more market-oriented economies. Part 3 reports on basic conditions and trends, key issues, major problems and efforts to resolve them, and recent developments in each of the major resource categories, from population and human development to energy to atmosphere and climate. Where data exist, the chapters give a 20-year perspective on trends in the physical environment - spanning the time between the first United Nations Conference on the Environment and UNCED. Supporting data, as well as the core data tables from the World Resources Data Base, are found in Part 4. Chapters have been processed separately for inclusion on the data base

These six case studies examined the use of different biodiesel blends as fuel supply sources for businesses in British Columbia (BC). In the first case study, 6 municipalities participated in a pilot program designed to compare the performance of biodiesel and diesel fuels. Each municipality operated 2 base vehicles running on conventional diesel along with 2 similar vehicles which used biodiesel. Real time emissions tests and analyses of the vehicles using biodiesel were also conducted by 2 of the participating municipalities. All municipalities participating in the study agreed to purchase significant volumes of biodiesel. The second case study described a pilot study conducted by the City of Vancouver's equipment services branch in 2004. As a result of the study, the city now has over 530 types of equipment that use biodiesel. The third case study described a program designed by TSI Terminals in Vancouver to assess the emission reduction impact of using biodiesel at its port facility. Six different pieces of equipment were used to confirm that biodiesel could be used throughout the terminal. Test results confirmed that biodiesel blends could be used to reduce emissions. Overall emissions were reduced by 30 per cent. The fourth case study described a waste renderer that used a fleet of 36 trucks to deliver raw products to its plants. The company made the decision to use only biodiesel for its entire fleet of trucks. Since July 2005, the company has logged over 1.7 million km using biodiesel blends. The fifth case study described a salmon hatchery that switched from diesel to biodiesel in order to reduce emissions. The biodiesel blends are used to fuel the hatchery's 2 diesel generators. The hatchery has reduced emissions of greenhouse gases (GHGs) by an estimated 1800 tonnes annually. The sixth case study described how the Township of Langley has started using biodiesel for its entire fleet of of approximately 250 pieces of equipment. The township has not

Full Text Available Renewable energy is a socially and politically defined category of energy sources. Renewable energy is generally defined as energy that comes from resources which are continually replenished on a human timescale such as sunlight, wind, rain, tides, waves and geothermal heat. About 16% of global final energy consumption comes from renewable resources, with 10% of all energy from traditional biomass, mainly used for heating, and 3.4% from hydroelectricity. New renewables (small hydro, modern biomass, wind, solar, geothermal, and biofuels accounted for another 3% and are growing rapidly. This paper seeks is aimed at presenting the impact solar energy could have on a world level given the finitude, reachability and ever increasing prices of fossil fuels. As a case study we will present the solar energy industry in Germany emphasizing the advantages and disadvantages this form of energy has in this country and worldwide.

Teaching Introductory Oceanography through Case Studies: Project based approach for general education students

Farnsworth, K. L.; House, M.; Hovan, S. A.

2013-12-01

A recent workshop sponsored by SERC-On the Cutting Edge brought together science educators from a range of schools across the country to discuss new approaches in teaching oceanography. In discussing student interest in our classes, we were struck by the fact that students are drawn to emotional or controversial topics such as whale hunting and tsunami hazard and that these kinds of topics are a great vehicle for introducing more complex concepts such as wave propagation, ocean upwelling and marine chemistry. Thus, we have developed an approach to introductory oceanography that presents students with real-world issues in the ocean sciences and requires them to explore the science behind them in order to improve overall ocean science literacy among non-majors and majors at 2 and 4 year colleges. We have designed a project-based curriculum built around topics that include, but are not limited to: tsunami hazard, whale migration, ocean fertilization, ocean territorial claims, rapid climate change, the pacific trash patch, overfishing, and ocean acidification. Each case study or project consists of three weeks of class time and is structured around three elements: 1) a media analysis; 2) the role of ocean science in addressing the issue; 3) human impact/response. Content resources range from textbook readings, popular or current print news, documentary film and television, and data available on the world wide web from a range of sources. We employ a variety of formative assessments for each case study in order to monitor student access and understanding of content and include a significant component of in-class student discussion and brainstorming guided by faculty input to develop the case study. Each study culminates in summative assessments ranging from exams to student posters to presentations, depending on the class size and environment. We envision this approach for a range of classroom environments including large group face-to-face instruction as well as hybrid

Breast cancer is the most common malignancy in women around the world. Information on the incidence and mortality of breast cancer is essential for planning health measures. This study aimed to investigate the incidence and mortality of breast cancer in the world using age-specific incidence and mortality rates for the year 2012 acquired from the global cancer project (GLOBOCAN 2012) as well as data about incidence and mortality of the cancer based on national reports. It was estimated that 1,671,149 new cases of breast cancer were identified and 521,907 cases of deaths due to breast cancer occurred in the world in 2012. According to GLOBOCAN, it is the most common cancer in women, accounting for 25.1% of all cancers. Breast cancer incidence in developed countries is higher, while relative mortality is greatest in less developed countries. Education of women is suggested in all countries for early detection and treatment. Plans for the control and prevention of this cancer must be a high priority for health policy makers; also, it is necessary to increase awareness of risk factors and early detection in less developed countries.

2015-01-01

Recent developments in "Big Data" have brought significant gains in the ability to process large amounts of data on commodity server hardware. Stream computing is a relatively new paradigm in this area, addressing the need to process data in real time with very low latency. While this approach has been developed for dealing with large scale data from the world of business, security and finance, there is a natural overlap with clinical needs for physiological signal processing. In this work we present a case study of streams processing applied to a typical physiological signal processing problem: QRS detection from ECG data.

Field Balancing in the Real World: Part 2

1999-01-01

This paper is a follow-up to an earlier paper, Field Balancing in the Real World, which was presented at CSI Reliability Week 1997 in Nashville. Case studies of excessive vibrations on fans at ORNL will be discussed. Except for a few small sections from the earlier paper, this paper is entirely new. The case studies are new. As in the first paper, all fans are rigid-rotor type fans. Normal operation, therefore, is at less than the shaft's first critical speed. The presentation of case studies with root cause problems other than unbalance is a major departure from the first paper. We believe they belong here, since unbalance is suspected most of the time when a fan is vibrating excessively, even when it is not the root cause. In reality, unbalance is the underlying cause of the excess vibration on fans we have fixed at ORNL only about half the time. Furthermore, the analyst's credibility could be called into question upon an unsuccessful attempt at field balancing when underlying causes are later discovered and fixed. A demonstration will follow the case study presentation. The additional tests described in this paper to confirm centrifugal force (probable unbalance) will be performed

The energy of patients and members of the public worldwide who care about improving health is a huge, but still largely unrecognized and untapped, resource. The aim of patient engagement is to shift the clinical paradigm from determining "what is the matter?" to discovering "what matters to you?" This article presents four case studies from around the world that highlight the proven and potential abilities of increased patient engagement to improve health outcomes and reduce costs, while extending the reach of treatment and diagnostic programs into the community. The cases are an online mental health community in the United Kingdom, a genetic screening program in the United Arab Emirates, a World Health Organization checklist for new mothers, and a hospital-based patient engagement initiative in the United States. Evidence from these and similar endeavors suggests that closer collaboration on the part of patients, families, health care providers, health care systems, and policy makers at multiple levels could help diverse nations provide more effective and population-appropriate health care with fewer resources.

Full Text Available As one of the new producing approaches, lean production has brought in new opportunities for producers all around the world. Many producers have adopted the technique for surviving the growing world market. By combining competitive advantages, lean attributes, and lean enablers as three factors, the present study attempts to determine the most suitable enablers for improvement of lean attributes in a case study. Quality Function Deployment (QFD in fuzzy environment and House of Quality (HOQ matrix, successfully employed for development of new products, are adopted as approach of the study. Weights of competitive advantages, lean attributes and enablers are calculated through fuzzy analysis hierarchy process (FAHP, while fuzzy logarithmic least square method (LLSM is used in calculation of the weights. Throughout the methodology, fuzzy logic is the basis for translating linguistic judgments required for the relationships and correlation matrix to numerical values. Moreover, final ranking of lean enablers is represented through area ranking method and taking into account various techniques of decision makers’ risk. Finally, a case study in automotive industry is introduced to demonstrate the implementation of the proposed methodology.

Novel therapies need to be evaluated in normal clinical practice to allow a true representation of the treatment effectiveness in real-world settings. The Salford Lung Study is a pragmatic randomised controlled trial in adult asthma, evaluating the clinical effectiveness and safety of once-daily fluticasone furoate (100 μg or 200 μg)/vilanterol 25 μg in a novel dry-powder inhaler, versus existing asthma maintenance therapy. The study was initiated before this investigational treatment was licensed and conducted in real-world clinical practice to consider adherence, co-morbidities, polypharmacy, and real-world factors. Asthma Control Test at week 24; safety endpoints include the incidence of serious pneumonias. The study utilises the Salford electronic medical record, which allows near to real-time collection and monitoring of safety data. The Salford Lung Study is the world's first pragmatic randomised controlled trial of a pre-licensed medication in asthma. Use of patients' linked electronic health records to collect clinical endpoints offers minimal disruption to patients and investigators, and also ensures patient safety. This highly innovative study will complement standard double-blind randomised controlled trials in order to improve our understanding of the risk/benefit profile of fluticasone furoate/vilanterol in patients with asthma in real-world settings.

With the globalization and rapid development every filed is taking an increasing interest in physical geography and human economics. There is a surging demand for small scale world map in large formats all over the world. Further study of automated mapping technology, especially the realization of small scale production on a large scale global map, is the key of the cartographic field need to solve. In light of this, this paper adopts the improved model (with the map and data separated) in the field of the mapmaking generalization, which can separate geographic data from mapping data from maps, mainly including cross-platform symbols and automatic map-making knowledge engine. With respect to the cross-platform symbol library, the symbol and the physical symbol in the geographic information are configured at all scale levels. With respect to automatic map-making knowledge engine consists 97 types, 1086 subtypes, 21845 basic algorithm and over 2500 relevant functional modules.In order to evaluate the accuracy and visual effect of our model towards topographic maps and thematic maps, we take the world map generalization in small scale as an example. After mapping generalization process, combining and simplifying the scattered islands make the map more explicit at 1 : 2.1 billion scale, and the map features more complete and accurate. Not only it enhance the map generalization of various scales significantly, but achieve the integration among map-makings of various scales, suggesting that this model provide a reference in cartographic generalization for various scales.

Oderda, Gary; Sifford-Wilson, S Monet

2012-06-01

Faced with competition from other drugs and therapies, drug manufacturers may be able to use comparative effectiveness research (CER) to help reduce barriers to a new drug's adoption and integration into formularies. But few examples exist to show how CER can be used effectively and whether the data can make a difference. To examine how CER can help strengthen a new drug's entry into the market and integration into formularies, and how ongoing CER might be valuable as a drug is implemented in the real world. A roundtable of 9 representatives from health plans, including formulary decision makers, evaluated how CER in phase 3 development of a new drug can add to the drug's strength of evidence, helping decision makers understand how and where to integrate that drug into a formulary. The round table participants viewed, as a case study, the development of liraglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist for adults with type 2 diabetes that was approved by the FDA in January 2010. With this drug, CER was incorporated into an extensive type 2 diabetes clinical development program, comparing how the drug worked in comparison with other established therapies. Although there are many antidiabetic drugs available for use, patients with type 2 diabetes often need additional agents. The FDA approved liraglutide with the conclusion that benefits of the drug outweighed potential risks but noted the association with pancreatitis in humans and animal data that showed rare medullary thyroid cancer associated with liraglutide. Roundtable participants agreed that while pre-launch CER can be valuable, ongoing real-world research is also important for confirming expected results, identifying additional uses and indications and managing risks. The participants also suggested opportunities for additional CER studies and made recommendations for manufacturers. Roundtable thought leaders agreed that well-planned trial designs incorporating CER result in high

One of the main challenges of today's society is the need to fulfill at the same time the two sides of the dichotomy between the growing energy demand and the need to look after the environment. Smart Grids are one of the answers: intelligent energy grids which retrieve data about the environment through extensive sensor networks and react accordingly to optimize resource consumption. In order to do this, the Smart Grids need to understand the existing relationship between energy demand and a set of relevant climatic variables. All smart “systems” (buildings, cities, homes, consumers, etc.) have the potential to employ their intelligence for self-adaptation to climate conditions. After introducing the Smart World, a global framework for the collaboration of these smart systems, this paper presents the relationship found at experimental level between a range of relevant weather variables and electric power demand patterns, presenting a case study using an agent-based system, and emphasizing the need to consider this relationship in certain Smart World (and specifically Smart Grid and microgrid) applications.

After Fukushima Daiichi Accident, importance and public concern for Multi-Unit Risk (MUR) or Probabilistic Safety Assessment (PSA) have been increased. Most of nuclear power plant sites in the world have more than two units. These sites have been facing the problems of MUR or accident such as Fukushima. In case of South Korea, there are generally more than four units on the same site and even more than ten units are also expected. In other words, sites in South Korea also have been facing same problems. Considering number of units on the same site, potential of these problems may be larger than other countries. The purpose of this paper is to perform case study based on another paper submitted in the conference. MUR is depended on various site features such as design, shared systems/structures, layout, environmental condition, and so on. Considering various dependencies, we assessed Multi-Unit Station Black-out (MSBO) accident based on Hanul Unit 3 and 4 model. In this paper, case study for multi-unit risk or PSA had been performed. Our result was incomplete to assess total multi-unit risk because of two challenging issues. First, economic impact had not been evaluated to estimate multi-unit risk. Second, large uncertainties were included in our result because of various assumptions. These issues must be resolved in the future.

Full Text Available Since the beginning of the 21st century, the China-Islamic World relationship has gained more impetus and entered into the fast track of development due to increasing bilateral, regional and global strategic interests. From a strategic perspective, China focuses more on energy and resources, national security in relation to religious extremism, national separatism and terrorism, and changes of regional geo-strategic structures in the Islamic World. Along with increasing mutual interests and the role of China in the Islamic World (including Central Asia, West Asia, South Asia and South-East Asia, political, economic and security relations between China and the Islamic World have been of great significance. As regards this, the recent developments of the relationships between China and both the Central Asian as well as the West Asian States can be used as examples. During these processes, the bilateral and multilateral cooperative regimes, such as Shanghai Cooperative Organization (SCO and Sino-Arab Co-operation Forum (SACF, were established. In the future, the regional challenges in the Islamic World and the rising role of Central Asia, West Asia, South Asia and South-East Asia and their competitors from current great powers, including the U.S.A., Russia, India, Japan and the EU, will have an impact on the relationship between China and the Islamic World.

After the adjustment of disciplinary categorization of Chinese colleges in 2011, world history, along with Chinese history and archeology, became the first-level disciplines in history. As a first-level discipline, world history has a meaning clearly different from its western sense: it is not a simply course, nor a single field, but a disciplinary system combined by many second-level disciplines, including ancient world history, modern world history, history of specific nations or regions, and history of specialized subjects.

The Source of Variation in Policies around the World: The Case of Protection of Human Health from Extremely Low Frequency Electromagnetic Fields

International Nuclear Information System (INIS)

Kandel, S.

2006-01-01

Scientific evidence supposedly plays a dominant role in environmental and public health regulation. This paper uses the example of Extremely Low Frequency Electromagnetic Fields regulation to test whether this is indeed the case. The paper first shows that there exists a significant variation in health protection policies for Extremely Low Frequencies Extremely Low Frequency Electromagnetic Fields around the world. Some countries adopt the international scientific-based guidelines while other countries choose to apply additional precautionary regulations of varying severity. Electromagnetic Fields policy makers around the world indicate that the Cost Benefit Analysis is one of the parameters considered for their choice among various policy options. A simple Cost Benefit Analysis framework is presented, utilizing scientific evidence on health risks from Extremely Low Frequencies as well as parameter values used in the Cost Benefit Analysis studies from California, Netherlands, Israel, and the United Kingdom to determine the justification of using several mitigation techniques. This Cost Benefit Analysis using data from the different countries leads to a clear conclusion: under all parameter values considered, only the low cost intervention measures, such as re-phasing and compacting lines, are justified. Re-routing lines, except in cases of very close proximity to residences, and under grounding existing lines cannot be justified due to the high costs involved and the small health benefits that are projected. Since the stringent policies cannot be accomplished with the low-cost measures, this suggests that if the Cost Benefit Analysis were indeed the basis for the policies implemented in different countries, one would expect a smaller variation in the worldwide policies observed today. The divergence between the policies that are implemented and those that can be supported by the Cost Benefit Analysis suggests that the Cost Benefit Analysis is either not used to

The impact of Body Worlds on adult visitors' knowledge on human anatomy: A preliminary study.

Fonseca, Guilherme R B C; Finn, Gabrielle M

2016-05-01

Body Worlds is an anatomical exhibition that shows human remains to the public. It has been considered controversial since it raises ethical tensions and issues. However, organizers and supporters of Body Worlds have claimed the exhibition is intended to promote visitors' understanding over the human body. Despite these claims, no studies were found that support or refute the hypothesis that a visit to Body Worlds increases the public's objective knowledge on human anatomy. Consequently, the objective of this study was to determine the impact of Body Worlds on anatomical knowledge. We constructed and delivered a questionnaire to both a previsit random sample and a postvisit random sample of visitors of Body Worlds' event Facets of Life, in Berlin. The questionnaire was available in both English and German languages and contained (a) basic sociodemographic questions and (b) a valid and reliable anatomy quiz. The quiz consisted of 16 multiple-choice questions that assessed the ability to identify the location of major anatomical structures on the human body. Average scores achieved on the quiz by the postvisit sample (X¯= 9.08, s = 2.48, n = 164) were significantly higher (unpaired t = 3.3957, P = 0.0008) than those achieved by the previsit sample (X¯= 8.11, s = 2.69, n = 167). Our results suggest that a visit to Body Worlds' event Facets of Life may have a beneficial effect in anatomical knowledge. However, further studies with better empirical designs and fewer limitations are needed to confirm our results. © 2016 Wiley Periodicals, Inc.

Full Text Available Purpose The purpose of this study was to conduct a strengths, weaknesses, opportunities, and threats (SWOT analysis of integrating the World Health Organization (WHO patient safety curriculum into undergraduate medical education in Pakistan. Methods A qualitative interpretive case study was conducted at Riphah International University, Islamabad, from October 2016 to June 2017. The study included 9 faculty members and 1 expert on patient safety. The interviews were audiotaped, and a thematic analysis of the transcripts was performed using NVivo software. Results Four themes were derived based on the need analysis model. The sub-themes derived from the collected data were arranged under the themes of strengths, weaknesses, opportunities, and threats, in accordance with the principles of SWOT analysis. The strengths identified were the need for a formal patient safety curriculum and its early integration into the undergraduate program. The weaknesses were faculty awareness and participation in development programs. The opportunities were an ongoing effort to develop an appropriate curriculum, to improve the current culture of healthcare, and to use the WHO curricular resource guide. The threats were attitudes towards patient safety in Pakistani culture, resistance to implementation from different levels, and the role of regulatory authorities. Conclusion The theme of patient safety needs to be incorporated early into the formal medical education curriculum, with the main goals of striving to do no harm and seeing mistakes as opportunities to learn. Faculty development activities need to be organized, and faculty members should to be encouraged to participate in them. The lack of a patient safety culture was identified as the primary reason for resistance to this initiative at many levels. The WHO curriculum, amended according to local institutional culture, can be implemented appropriately with support from the corresponding regulatory bodies.

THE ROLE OF MODERN WORLD CURRENCIES IN PRIVATE SECTOR

2018-01-01

Full Text Available The authors compare the factors determining the scale of international world currencies transactions as saving means and means of payment. The change in the role of the US dollar, euro, pound sterling, Japanese Yen and Chinese Yuan in the private sector over the past few decades are also juxtaposed with the previous factors. The conclusion is made about an incomplete correlation of modern conditions determining the international demand for a common European and Chinese national currency, and the demand for the volumes of their use in the world. On the basis of the comparative analysis of the volumes of world currencies transactions in different spheres, the authors demonstrate the top priority of the means of payment function in the process of calling forth the demand for these means on the part of non-residents using them as payment and saving means. It is proved that the main reasons of maintaining the dominant role of the US dollar as a world currency in the private sector are the leading position of the American economy concerning its contribution into the creation of the world product, support of a relatively high level of the development of the national financial market of the USA, long-term period of the American currency being world unit of account, low operation costs concerning the operations with them and also the inertia character of private actors of the world economy. It is shown that in a short-term period in case of a further growth of the economic power of the euro zone and China, provision of a complete convertibility of the Yuan and removal of the restrictions for non-residents in the Chinese financial market and also in case of maintaining a stable economic situation in the USA, the function of the world money will be carried out mainly by the American dollar.

Noah’s Ark or World Wild Web? Cultural Perspectives in Global Scenario Studies and Their Function for Biodiversity Conservation in a Changing World

Full Text Available In this paper, we review the Intergovernmental Panel on Climate Change and the Millennium Ecosystem Assessment Scenarios and their assumptions on biodiversity conservation, using a framework based on the cultural theory (CT perspectives. We explored an adaptation of the CT typology and the significance of some underrepresented worldviews for discussions on conservation in a changing world. The evaluation of the assumptions on biodiversity conservation in the scenario studies and storylines adds to our understanding of the socio-cultural dimensions of biodiversity loss in a changing world. It contributes to an understanding of the worldviews underlying the complex debates on biodiversity conservation and sustainable development. Making such assumptions and world views explicit will help policymakers and conservationists discuss the diversity of conservation strategies in the face of uncertainty.

The reproducibility of the World Health Organization 2008 classification for myelodysplastic syndromes is uncertain and its assessment was the major aim of this study. The different peripheral blood and bone marrow variables required for an adequate morphological classification were blindly evaluated by four cytomorphologists in samples from 50 patients with myelodysplastic syndromes. The degree of agreement among observers was calculated using intraclass correlation coefficient and the generalized kappa statistic for multiple raters. The degree of agreement for the percentages of blasts in bone marrow and peripheral blood, ring sideroblasts in bone marrow, and erythroid, granulocytic and megakaryocytic dysplastic cells was strong (P<0.001 in all instances). After stratifying the percentages according to the categories required for the assignment of World Health Organization subtypes, the degree of agreement was not statistically significant for cases with 5-9% blasts in bone marrow (P=0.07), 0.1-1% blasts in peripheral blood (P=0.47), or percentage of erythroid dysplastic cells (P=0.49). Finally, the interobserver concordance for World Health Organization-defined subtypes showed a moderate overall agreement (P<0.001), the reproducibility being lower for cases with refractory anemia with excess of blasts type 1 (P=0.05) and refractory anemia with ring sideroblasts (P=0.09). In conclusion, the reproducibility of the World Health Organization 2008 classification for myelodysplastic syndromes is acceptable but the defining criteria for blast cells and features of erythroid dysplasia need to be refined.

Light Up The World (LUTW) is an organization dedicated to bringing renewable energy (RE) based solid state lighting (SSL) to the developing world. A typical SSL system consists of white light emitting diodes (WLEDs), a renewable energy source, and an energy storage device. Sufficient energy to operate a system with 2 1W lamps can be obtained using a 5W photovoltaic (PV) module. Use of the systems will help to eliminate the use of fuel-based lighting sources and their associated environmental impacts and safety and health hazards. This paper included a case study of a rural African community, as well as case studies of refugee camps in Sri Lanka and Nepal. The socio-economic impacts of SSL were evaluated, including potential impacts on taxation, business activities, and economic growth. The paper also demonstrated how the implementation of SSL will achieve all 8 of the United Nations' millennium development goals. 14 refs., 9 figs.

The purpose of this study was to determine the prevalence of odontogenic cysts at the Pernambuco School of Dentistry - Universidade de Pernambuco (Brazil) and compare this prevalence with other international studies. Data for the study were obtained from reports of patients diagnosed with odontogenic cysts between 1992 and 2007. Case records of patients who fit the Histological Classification of the World Health Organization (2005) were included. The following variables were analyzed: gender, age group, anatomical location, histological type and ethnic background. Odontogenic cysts accounted for 9.94% of all lesions biopsied throughout the study period. Mean patient age was 28.9 years and 57.6% of the patients were males (P > 0.05). Radicular cyst was the most prevalent histological type (52.2%), followed by dentigerous cyst (30.7%). Regarding ethnic background, 41.8 % of the patients were of African descent, followed by Caucasians and other ethnic groups (P > 0.05). The mandible was the most prevalent site of the lesions (56%). Odontogenic cysts appear to have a distinct predilection for the male gender, the second and third decades of life (P keratocysts from the new WHO classification has not altered the order of the most prevalent cysts in the maxillofacial complex.

Irani, Soussan; Esfahani, Alireza Monsef; Ghorbani, Anahita

2016-01-01

Backgrounds: Lichen planus is a chronic systemic disease and oral mucosa is commonly involved. Oral lichen planus (OLP) most commonly affects middle-aged women. The prevalence of the disease ranges between 0.5% and 2.6% in the general population and the range of malignant transformation varies between 0% and 10%. Objectives: To assess the rate of malignant transformation of OLP samples. Materials and Methods: This retrospective study was carried out on 112 medical records of patients with histological diagnosis of OLP who attended the Department of Pathology at the Educational Hospital from 2005 to 2012. H&E-stained slides were reviewed by two pathologists using strict clinical and histopathological diagnostic World Health Organization (WHO) criteria. Dysplastic changes were diagnosed and graded according to the latest WHO classification. Results: Of the 112 cases diagnosed as OLP, there were 39 males and 73 females and the patients’ ages ranged from 15 to 86 years (mean age 44.5 years). The erosive form with fifty cases was the most common clinical type and the papular type with one case was the least common clinical type. Regarding the site, the buccal mucosa was the most common site with 52 cases. Totally, dysplastic changes were found in 12 samples, among them five cases showed mild dysplasia and seven cases showed moderate dysplasia. One case developed oral squamous cell carcinoma after 3 years. Conclusion: OLP is considered as a premalignant condition by the WHO and several authors. Although the malignancy rate is not so high, to reduce morbidity and mortality from cancer arising on OLP lesions, a regular follow-up examination is recommended. PMID:27721603

Directory of Open Access Journals (Sweden)

Jerry Bentley

2012-05-01

Full Text Available Building on his long career as a distinguished historian of early modern Europe, John Miles Headley has recently turned his gaze to the influence of Europe in the larger world. In The Europeanization of the World, Headley makes an insistent case for the uniqueness of European values—particularly human rights and democracy—and argues that these values are Europe’s most precious gifts to the larger world. Without seeking to diminish the remarkable intellectual and cultural achievements of European peoples, this presentation will suggest a more nuanced view of relations between Europe and the larger world. Human rights and democracy mean different things to different peoples in different contexts at different times, and there have in fact been numerous expressions of both in societies beyond Europe. Furthermore, European theorists of human rights and democracy drew influence from societies beyond Europe. To the extent that the Europeanization of the world is a persuasive idea, it is possible only because of a prior globalization of Europe.

Full Text Available It is not easy to study socially marginalized groups such as gays, ethnic minorities, and others. This is, however,an extremely relevant topic in the consumer behavior area since the status of members of a modern consumersociety is largely denied to stigmatized social groups (Barbosa, 2006. The objective of this work is to shed lighton how gay men in Rio de Janeiro use the discourse associated with their possessions to build and maintain thesymbolic and hierarchical boundaries between the gay and heterosexual worlds, as well as to investigate the roleconsumption plays in this boundary setting. An ethnographic observation of a group of gay men in Rio deJaneiro was conducted, along with 20 semi-structured interviews with openly gay men between 2005 and 2008.The results suggest that: (a the world culturally built by gays seems to be divided into a gay world and aheterosexual world, where the division between these two worlds not only happens in their minds, but also intheir possessions and purchasing decisions; (b the meaning of gay mens’ places of consumption range fromprofane to sacred along their lives; and (c in the gay world, the body is seen both as a cultural construction andas an asset.

Three-dimensional virtual worlds are becoming very popular among educators in the medical field. Virtual clinics and patients are already used for case study and role play in both undergraduate and continuing education levels. Dental education can also take advantage of the virtual world's pedagogical features in order to give students the opportunity to interact with virtual patients (VPs) and practice in treatment planning. The objective of this study was to design and evaluate a virtual patient as a supplemental teaching tool for pediatric dentistry. A child VP, called Erietta, was created by utilizing the programming and building tools that online virtual worlds offer. The case is about an eight-year old girl visiting the dentist with her mother for the first time. Communication techniques such as Tell-Show-Do and parents' interference management were the basic elements of the educational scenario on which the VP was based. An evaluation of the simulation was made by 103 dental students in their fourth year of study. Two groups were formed: an experimental group which was exposed to the simulation (n=52) and a control group which did not receive the simulation (n=51). At the end, both groups were asked to complete a knowledge questionnaire and the results were compared. A statistically significant difference between the two groups was found by applying a t test for independent samples (Pworld offers significant learning potential when used as a supplement to the traditional teaching techniques.

The World of Nothing

2017-11-01

Full Text Available The article presents a comparative analysis of knowledge about the world of nothingness. J. Boehme pointed to the fact that the world of Nothing is everlasting emptiness, where and wherein the material world could emerge. But the thing is that the world of absolute emptiness did not vanish at the moment of beginning of the world, quite the reverse, it has somehow been permanently enlarging. What will happen next is still a question. Perhaps our world will begin to be moving back on a new spiral of development, perhaps a real transition to the world of nothing will have appeared in this subtle place. For the present it is clear that these two worlds have not touched each other in mutually beneficial communication so far, and everything from our world passes into the world of nothing, and in general, the world of nothing ontologically appears to be much more existential than the world of apparent reality. What can give us some kind of key point at least, be some kind of organon in interaction with these two worlds - with the world of Nothing in which there is no matter and which cannot be perceived by any senses, and with the world of matter in which all senses are unstable and changeable? In our opinion, the only beacon and the instrument of knowledge can be the mind. To understand this phenomenon, by benefiting from a comparative methodology, this study investigates opinions of a number of philosophers, J. Boehme, G.V.F. Hegel, M. Heidegger, and J.P. Sartre, on the existence of the world of nothing.

Oil Prophets: Looking at World Oil Studies Over Time

Energy Technology Data Exchange (ETDEWEB)

Andrews, Steve [Denver, CO (United States); Udall, Randy [Carbondale, CO (United States)

2003-07-01

Early reports of world oil assessments date back to the 1940s. In the intervening 60 years, the number of studies projecting Estimated Ultimately Recoverable (EUR) oil reached well over 50. A detailed search would undoubtedly lengthen the list that will be provided with this paper. How have their estimates fared? Given general agreement that we haven't yet reached the halfway point in eventual production, it's too early to offer definitive assessments. However, several factors stand out: The learning curve. It took over a decade of effort for projections to emerge that are in line with lower-end projections of more recent studies. The learning curve has flattened. For those individuals and groups who conducted multiple studies, their subsequent EUR numbers generally trend higher. The analyses lack a common definitional framework. Beyond crude oil, what liquids are included? Heavy oil and tar sands? Some or all gas liquids? Polar and deepwater oil? While the ability to locate, evaluate and extract oil in the field has drastically improved over time, analysts continue to be hampered by a lack of access to definitive data plus disagreements about assessment methodologies. Striving to determine how many petroleum liquids we have left is a useful exercise, but primarily as a means to help determine when daily worldwide production is likely to peak. To that end, a key point is that 'not all liquids resources are created equal'; many of the larger new fields are located in harsh and remote regions, in politically unstable environments, or require large energy inputs during extraction. Production rates and costs will vary dramatically. Since demand is somewhat fickle, identifying a year or range of years when liquids production will peak qualifies as part art, part science. That said, the paper will list estimates by 'oil prophets' as to when they project that petroleum liquids production will peak. The estimates range from 1995 to 2025. How have their estimates fared

2017-01-01

Full Text Available Objective: Psoriasis is a chronic, relapsing and disfiguring dermatological disorder with a significant effect on occupational, social, and other areas of functioning. Psychological stress has been known to have a significant role in the onset and exacerbation of this illness. To study the prevalence of psychiatric morbidity in psoriasis and the influence of specified demographic, psychological, social and illness-related variables. Methods: The study was carried out at a tertiary care hospital in a large urban setup. In this case–control study, 100 cases of psoriasis were studied in comparison with healthy controls who were matched for sociodemographic profile. The participants were given a sociodemographic questionnaire, clinical profile sheet, and psoriasis area and severity index (PASI. General Health Questionnaire-12 (GHQ-12 was used to screen for psychological distress, and subsequently, Hospital Anxiety and Depression Scale for screening for depression and anxiety and World Health Organization Quality of Life-BREF scale for assessing the quality of life (QOL were administered. The results obtained were analyzed for evaluating the psychiatric morbidity and its various correlates. Appropriate statistical analysis was done using SPSS 21. Results: Using GHQ-12 cutoff score (≥3 for psychological distress, the overall prevalence of psychological distress was significantly more in cases of in comparison to healthy controls with an odds ratio of 8.54 (95% confidence interval 3.16–23.07, P < 0.0001. Statistical analysis showed a statistically significant correlation of educational status with QOL and severity of skin lesions (PASI with anxiety level. Severe skin lesions, more so on visible body parts were associated more commonly with psychological distress. Conclusions: All patients of psoriasis should be educated about the nature of the illness and screened for psychological distress. Dermatologists and family members should be educated to

1998-12-31

This thesis discusses implementation and application of Geographical Information systems (GIS) in international River Basin Organizations (RBOs) in the Third World. Third World countries sharing the same river basin are increasingly experiencing conflicts because they exploit the same water resource. Empirical knowledge is derived from two case studies. (1) The Mekong River Commission Secretariat`s experiences in applying GIS are investigated. The conditions assessed are related to institutional, funding, expertise, training and technology issues for successful application of GIS. (2) The prospects for the implementation of GIS at a future WATERNET Centre in Amman are investigated. Israel, Jordan and the Palestinian Authority have decided to establish a regional GIS Centre in the lower Jordan River Basin. The study assesses political, legal and institutional conditions for the successful implementation of GIS. It is concluded that implementing and applying GIS successfully in RBOs in the Third World is challenging, although not for technological reasons. 265 refs., 28 figs., 13 tabs.

Full Text Available INTRODUCTION: Snake bite envenomation is a frequently encountered problem in tropical countries like India, especially in the rural areas of south India. Most of the victims are farmers. The World Health Organization has estimated that nearly 1,25,000 deaths occur among 2,50,000 poisonous snake bites world - wide, of which India accounts for 10,000 deaths. Acute Kidney Injury (AKI is an important consequence of a snake bite and its proper supportive management after the anti - venom administration is of utmost importance, for a good patient outcome. AIM AND OBJECTIVES : To assess the incidence of Acute Kidney Injury in patients with hemotoxic snake envenomation . To assess the etiological factors involved in Acute Kidney Injury on snake bite victims. METHODOLOGY: This prospective study was carried out at King George Hospital, Visakhapatnam, Andhra Pradesh. It is a tertiary care government hospital, attached to Andhra Medical College, Visakhapatnam. STUDY DESIGN: This was a prospective and descriptive type of study. RESULTS: A total of 214 cases of hemotoxic snake bite were included in this study, who were admitted in the hospital from September 2012 to August 2014. The incidence of renal failure in hemotoxic snake bite is 23.3%. The probable etiology of AKI in snake bite victims is DIC in 48% of cases, direct nephrotoxicity in 24% of cases. CONCLUSION: This study concludes that Acute Kidney Injury occurs in 23.3% of cases of hemotoxic snake bite. DIC is the most common etiologic factor for AKI in snake bite followed by direct nephrotoxicity, hypotension, capillary leak syndrome and sepsis

To review Campylobacter cases in England and Wales over 2 decades and examine the main factors/mechanisms driving the changing epidemiology. A descriptive study of Campylobacter patients between 1989 and 2011. Cases over 3 years were linked anonymously to postcode, population density, deprivation indices and census data. Cases over 5 years were anonymously linked to local weather exposure estimates. Patients were from general practice, hospital and environmental health investigations through primary diagnostic laboratories across England and Wales. There were 1 109 406 cases. Description of changes in Campylobacter epidemiology over 23 years and how the main drivers may influence these. There was an increase in Campylobacter cases over the past 23 years, with the largest increase in people over 50 years. Changes in the underlying population have contributed to this, including the impacts of population increases after World War I, World War II and the 'baby boom' of the 1960s. A recent increase in risk or ascertainment within this population has caused an increase in cases in all age groups from 2004 to 2011. The seasonal increase in cases between weeks 18 (Early May) and 22 (Early June) was consistent across ages, years and regions and was most marked in children and in more rural regions. Campylobacter prevalence by week in each region correlated with temperature 2 weeks before. There were higher prevalences in areas with a low population density, low deprivation and lower percentage of people of ethnic origin. Data from sero-phage and multilocus sequence typing show a few common types and many uncommon types. The drivers/mechanisms influencing seasonality, age distribution, population density, socioeconomic and long-term differences are diverse and their relative contributions remain to be established. Surveillance and typing provide insights into Campylobacter epidemiology and sources of infection, providing a sound basis for targeted interventions.

The aim of this study is to provide an overview of the scientific activity of different psychoanalytic schools of thought in terms of the content and production of case studies published on ISI Web of Knowledge. Between March 2013 and November 2013, we contacted all case study authors included in the online archive of psychoanalytic and psychodynamic case studies (www.singlecasearchive.com) to inquire about their psychoanalytic orientation during their work with the patient. The response rate for this study was 45%. It appears that the two oldest psychoanalytic schools, Object-relations psychoanalysis and Ego psychology or "Classical psychoanalysis" dominate the literature of published case studies. However, most authors stated that they feel attached to two or more psychoanalytic schools of thought. This confirms that the theoretical pluralism in psychoanalysis stretches to the field of single case studies. The single case studies of each psychoanalytic school are described separately in terms of methodology, patient, therapist, or treatment features. We conclude that published case studies features are fairly similar across different psychoanalytic schools. The results of this study are not representative of all psychoanalytic schools, as some do not publish their work in ISI ranked journals.

There is a rising interest for clinical cases in medicine. Actually, they don't necessarily conflict with the evidence-based medicine approach; rather, as several authors made clear, EBM-oriented case reports and clinical trials could be complementary. Cases and case series could even represent the first line of evidence and they are extremely valuable in discovering new pathologies and monitoring unexpected drug effects. They also play a relevant role in continuing medical education. The new section of Recenti Progressi in Medicina is edited by a prominent Italian research Institute (Istituto di Fisiologia Clinica, CNR). It focuses on a single case, guiding the physicians' decision-making from differential diagnosis to the treatment options.

Influenza outbreak during Sydney World Youth Day 2008: the utility of laboratory testing and case definitions on mass gathering outbreak containment.

Directory of Open Access Journals (Sweden)

Sebastiaan J van Hal

Full Text Available BACKGROUND: Influenza causes annual epidemics and often results in extensive outbreaks in closed communities. To minimize transmission, a range of interventions have been suggested. For these to be effective, an accurate and timely diagnosis of influenza is required. This is confirmed by a positive laboratory test result in an individual whose symptoms are consistent with a predefined clinical case definition. However, the utility of these clinical case definitions and laboratory testing in mass gathering outbreaks remains unknown. METHODS AND RESULTS: An influenza outbreak was identified during World Youth Day 2008 in Sydney. From the data collected on pilgrims presenting to a single clinic, a Markov model was developed and validated against the actual epidemic curve. Simulations were performed to examine the utility of different clinical case definitions and laboratory testing strategies for containment of influenza outbreaks. Clinical case definitions were found to have the greatest impact on averting further cases with no added benefit when combined with any laboratory test. Although nucleic acid testing (NAT demonstrated higher utility than indirect immunofluorescence antigen or on-site point-of-care testing, this effect was lost when laboratory NAT turnaround times was included. The main benefit of laboratory confirmation was limited to identification of true influenza cases amenable to interventions such as antiviral therapy. CONCLUSIONS: Continuous re-evaluation of case definitions and laboratory testing strategies are essential for effective management of influenza outbreaks during mass gatherings.

Ocean World Exploration and SLS: Enabling the Search for Life

Whether life exists on worlds other than Earth is one of the most compelling questions facing space science today. Given that, on Earth, life exists wherever water is found, worlds harboring large amounts of water are prime targets in the search for an answer to this question. Jovian moons Europa, Callisto, and Ganymede; Saturnian moons Enceladus and Titan; and possibly Neptune's Triton are all worlds in the outer solar system on which large quantities of water can be found in solid and liquid form. So compelling are these worlds as targets for scientific study that the United States Congress recently initiated a directive to NASA to create an "Ocean Worlds Exploration Program, comprised of frequent small, medium and large missions that poses the potential to revolutionize our understanding of the solar system and life within it, perhaps more profoundly event than the modern-day search for past or extant life on Mars. Any life detected at the remote "ocean worlds" in the outer solar system would likely have formed and evolved along an independent path from life on Earth itself, giving us a deeper understanding of the potential for broad variety amongst life in the universe. In NASA's robotic study of Mars, a key to the success of the "search for water" was the ability to conduct iterative exploration via a series of missions launched on a regular cadence based on 26-month cycles of prime planetary-alignment windows of reduced transit time. Through this cadence, NASA was able to send to Mars a series of orbiters and landers, using the knowledge gained from each mission to inform and refine the goals of the next. The ability to conduct iterative exploration in this manner could have a substantial impact on exploration of the "ocean worlds," allowing scientists to narrow their targets of interest in the search for life based on data sent back by successive missions. This ability is currently limited by the transit periods available from contemporary evolved expendable

Analysis of the decision-support function of policy assessment in real-world policy making in the field of poverty and social inequalities. Case study on migrant integration policies in the Brussels-Capital Region

Despite its high potential to support decision-making, the role of policy assessment in real-world policy making in the field of poverty and social inequalities remains largely questioned. In this study, we analyse policy assessment's role in a context of real-world policymaking, by means of a case study on a legislative proposal on integration policy for immigrant newcomers in the Brussels-Capital Region, for which we evaluate the potential effects on poverty and social inequalities. We first analyse the policy process surrounding the policy proposal – a process that is often treated as a black box within policy assessment research. Understanding the factors that influence and determine the decision-making process, enables us to gain insight into the potential decision-support function(s). Second, we develop an approach to policy assessment that aims to fully exploit its potential to contribute to the functions of both instrumental and conceptual learning. For this purpose, we propose to introduce the approach of realist evaluation and to focus on evaluating the underlying policy intervention theory from the perspective of poverty and social inequalities. Finally, we illustrate this new approach and its added value by applying it to the legislative proposal on integration policy and analyse its contribution to policy-oriented learning. - Highlights: •The field of policy assessment should draw on insights from policy studies. •We unpacked the policymaking black-box to identify the mechanisms of policy change. •The policy process is driven by an interaction of ideas, interests and institutions. •Policy assessment's potential lies in both instrumental and conceptual learning. •We propose to integrate realist evaluation's logic of inquiry within policy assessment.

Can virtual science foster real skills? A study of inquiry skills in a virtual world

Dodds, Heather E.

Online education has grown into a part of the educational market answering the demand for learning at the learner's choice of time and place. Inquiry skills such as observing, questioning, collecting data, and devising fair experiments are an essential element of 21st-century online science coursework. Virtual immersive worlds such as Second Life are being used as new frontiers in science education. There have been few studies looking specifically at science education in virtual worlds that foster inquiry skills. This quantitative quasi-experimental nonrandomized control group pretest and posttest study explored what affect a virtual world experience had on inquiry skills as measured by the TIPS (Test of Integrated Process Skills) and TIPS II (Integrated Process Skills Test II) instruments. Participants between the ages of 18 and 65 were recruited from educator mailing lists and Second Life discussion boards and then sorted into the experimental group, which received instructions to utilize several displays in Mendelian genetics at the Genome Island location within Second Life, or the control group, which received text-based PDF documents of the same genetics course content. All participants, in the form of avatars, were experienced Second Life residents to reduce any novelty effect. This study found a greater increase in inquiry skills in the experimental group interacting using a virtual world to learn science content (0.90 points) than a control group that is presented only with online text-based content (0.87 points). Using a mixed between-within ANOVA (analysis of variance), with an alpha level of 0.05, there was no significant interaction between the control or experimental groups and inquiry skills, F (1, 58) = .783, p = .380, partial eta squared = .013, at the specified .05 alpha level suggesting no significant difference as a result of the virtual world exercise. However, there is not enough evidence to state that there was no effect because there was a

Utilising real-world case studies illustrated by companies that have adopted this model (interviews with Saint-Gobain, L’Oréal, Tetra Pak, Bemis, and Bel Executives), it describes common patterns drawn from decades of hands-on experience, so as to present a theoretical approach together with the concrete application of its principles. WCOM, adopted by several multinational companies, is one of the more innovative management practises, as it integrates the best Continuous Improvement approaches (Lean, Total Productive Management, World Class Manufacturing) as well as the most innovative approaches in human dynamics like Change Leadership, Performance Behavior, Shingo Model, to name a few. Maximising reader insights into the successful implementation of such an approach, and explaining not only its potentialities, but also its implementation dy...

Resilience, or the process of adjusting well to risk, relies on constructive collaboration between youths and their social ecologies. Although the literature details the risks of an intellectual disability (ID), there is little explanation of why some young people cope well despite these risks. Accordingly, we report a multiple case study that affords insight into the resilience of 24 adolescents with ID. Using a draw-and-talk methodology, these young people explained their resilience as enabled primarily by supportive social ecologies (which facilitated behavioral and emotional regulation, encouraged mastery, treated them as agentic beings, and offered safe spaces). Adolescents' positive orientation to their life-worlds co-facilitated their resilience. These insights advance effective ways to champion the resilience of young people with ID.

Efforts at immunizing children against measles was intensified in Nigeria with nation-wide measles vaccination campaigns in 2005-2006, 2008 and 2011 targeting children between 9 and 59 months. However, there were measles outbreaks in 2010 and 2011 in Abia state Nigeria. This study seeks to find out if there is any association between measles immunization coverage and measles outbreak. This is a descriptive analysis of the 2007 to 2011 Abia state measles case-based surveillance data supplied to Abia state World Health Organization office and Abia State Ministry of Health by the disease surveillance and notification officers. As the proportion of cases with febrile rash who were immunized decreased from 81% in 2007 to 42% in 2011, the laboratory confirmed cases of measles increased from two in 2007 to 53 in 2011.Of the laboratory confirmed cases of measles, five (7%) occurred in children Abia state bearing in mind that measles immunization coverage in urban and rural areas was not markedly different.

Full Text Available In the third millennium of the Christian era, which is characterised by the emergence of a world economy and eventually a world society, the concept of world law is needed to embrace not only the traditional disciplines of public international law, and comparative law, but also the common underlying legal principles applicable in world trade, world finance, transnational transfer of technology and other fields of world economic law, as well as in such emerging fields as the protection of the world's environment and the protection of universal human rights. World law combines inter-state law with the common law of humanity and the customary law of various world communities.

Female genital mutilation, condemned by all UN member countries has spread throughout the world as a result of migratory flows and is practiced under the guise of a custom, tradition or culture. In Spain, it is punishable as a personal injury offence under the current penal code. A clinical case study reviewedthe main actions of the midwife in this kind of injury in a pregnant woman during labour. The data collected from the physical examination and the midwife's assessment according to the Virginia Henderson model are presented and a complete care plan developed. From the case it can be concluded that in the hospital area, midwives can and should reinforce and complete the work with these women and their families, of informing, educating and reinforcing the decision not to mutilate. This work should have been started in, the health centre. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.
