    Full Text Available The growing role of franchising at the global level requires its further improvement. This business model has great business potential, especially in the Serbian market, given the current underdevelopment and inaccessibility of information. At the core of our research, we outlined the characteristics of this business model, its impact on business development and at the same time we tried to draw the attention of domestic business entities to the benefits of franchising as a modern way of doing business. We start our research with a focus on the comparative analysis of Serbia, as a very poorly developed market. We then discuss the concept of franchising in Europe, with a special focus on Poland as a country that is ready to export franchising systems, and we continue by providing comparisons with the world's largest markets, namely, the USA and Canada. In this paper, we tried to elaborate on the economic viability of this project, as well as the increasing expansion and importance franchising has been experiencing in the last few years. Emphasis is placed on the use of franchise in many areas of business where there is the possibility of implementing both business models.

  2. Explaining the judicial independence of international courts: a comparative analysis

    DEFF Research Database (Denmark)

    Beach, Derek

    What factors allow some international courts (ICs) to rule against the express preferences of powerful member states, whereas others routinely defer to governments? While judicial independence is not the only factor explaining the strength of a given international institution, it is a necessary...... condition. The paper first develops three sets of competing explanatory variables that potentially can explain variations in the judicial independence of ICs. The causal effects of these explanatory variables upon variance in judicial independence are investigated in a comparative analysis of the ACJ, ECJ...

    Full Text Available The goal of this paper is to compare the characteristics of Polish and Czech companies which follow the Born Global internationalization model. More concretely, the analysis aims to discover the differences or similarities in terms of the internationalization paths of Polish and Czech SMEs in the characteristics of their managers in terms of the so-called “international vision” and in their innovativeness level. The introductory part of article provides a description of this internationalization model and the International New Ventures traits (INV and summarizes the recent studies on this topic conducted in Poland and Czech Republic. In the empirical part, the International New Ventures from the two countries are compared. The Polish sample includes 105 companies which were surveyed with use of computer assisted telephone interviews in autumn 2014. For the Czech Republic, the sample consists of 54 small and medium-sized companies, which were surveyed using the computer assisted web interviews from November 2013 till January 2014. The surveyed companies in both countries fulfilled the definition of Born Globals. Descriptive statistics, cross-tabulation analysis and non-parametric tests are applied to accomplish the goals of the paper.

    2012-07-01

    The oil industry is dynamic and global, being performed worldwide and by investors from several countries. In this sense, it is essential for investors to be informed of the legal frameworks in target countries and the differences between the legislation in those countries and their own legal systems. In this article, we will analyze the main differences on the environmental liability in Brazil, which is, currently, one of the most attractive markets in the oil and gas industry, the United States of America (US), the largest consumer of oil and the third producer around the world; and the European Union (EU) which concentrates the second largest global consumer, besides being the main player in the international and diplomatic relationships. Thus, the present paper, without the intent to exhaust the subject matter, aims at presenting comparisons between the legal environment of the three main players in the international oil and gas scenario, specifying not only the legal aspects of each of them, but also outlining the economic impacts generated over business investors from the oil industry, determining that although the differences in the basis of legal framework, all players have presented the liability and the duty to compensate.

    This paper examines selected components of social security system in India and compares them with their OECD counterparts. Historically, the Indian policy makers have viewed the pension system as a welfare measure and therefore, it lacks in financial professionalism, diversification, and in the belief that pension funds can also be treated as an asset. The Indian system is biased towards the organized formal sector as workers in this sector are benefitted with the provisions under various lab...

  7. International Migration and Gender in Latin America: A Comparative Analysis.

    Science.gov (United States)

    Massey, Douglas S; Fischer, Mary J; Capoferro, Chiara

    2006-12-01

    We review census data to assess the standing of five Latin American nations on a gender continuum ranging from patriarchal to matrifocal. We show that Mexico and Costa Rica lie close to one another with a highly patriarchal system of gender relations whereas Nicaragua and the Dominican Republic are similar in having a matrifocal system. Puerto Rico occupies a middle position, blending characteristics of both systems. These differences yield different patterns of female relative to male migration. Female householders in the two patriarchal settings displayed low rates of out-migration compared with males, whereas in the two matrifocal countries the ratio of female to male migration was much higher, in some case exceeding their male counterparts. Multivariate analyses showed that in patriarchal societies, a formal or informal union with a male dramatically lowers the odds of female out-migration, whereas in matrifocal societies marriage and cohabitation have no real effect. The most important determinants of female migration from patriarchal settings are the migrant status of the husband or partner, having relatives in the United States, and the possession of legal documents. In matrifocal settings, however, female migration is less related to the possession of documents, partner's migrant status, or having relatives in the United States and more strongly related to the woman's own migratory experience. Whereas the process of cumulative causation appears to be driven largely by men in patriarchal societies, it is women who dominate the process in matrifocal settings.

  9. Comparative analysis of fiscal terms for Alberta oil sands and international heavy and conventional oils

    International Nuclear Information System (INIS)

    Van Meurs, P.

    2007-01-01

    There are considerable differences between international heavy oil and Alberta oil sands projects, notably the high viscosity of the bitumen in the oil sands reservoirs. The oil sands bitumen do not flow to wells without heating the bitumen, thereby adding to the already high cost of Alberta oil sand operations. This report provided an economic comparison of Alberta oil sands and international heavy oil projects. It also included a brief scoping review to compare with conventional oil regimes. Full exploration costs including the costs of dry holes were allocated to conventional oil operations in order to obtain a proper comparison. This investigation included the costs of dry holes. The report was a follow up to an earlier study released on April 12, 2007 on the preliminary fiscal evaluation of Alberta oil sand terms. The report provided an economic framework and described project selection. It then provided a discussion of production, costs and price data. Four adjusted projects were presented and compared with Alberta. The Venezuelan royalty formula was also discussed. Last, the report provided a detailed fiscal analysis. Comparisons were offered with Cold Lake and Athabasca Mine. A review of some other fiscal systems applicable to conventional oil were also outlined. It was concluded that Alberta oil sands developments are very competitive. It would be possible to modestly increase government revenues, without affecting the international competitive position of Alberta with respect to conventional oil. There is also some possibility to increase the base royalty on the Alberta oil sands without losing competitiveness. tabs., figs

    2014-01-01

    The objective of this study is to perform a comparative analysis between the Brazilian legislation and internationals protocols, with respect to the quality control tests for computerized tomography. We used 07 references, published from 1998-2012: the Protocolo Brasileiro - Portaria 453/98 SVS/MS and the Guia de Radiodiagnostico Medico da ANVISA; Quality Assurance Programme for Computed Tomography: Diagnostic and Therapy Applications of the IAEA; European Protocol - European Guidelines on Quality Criteria for Computed Tomography of the EUR No. 16262 EN; Radiation Protection No. 162 - Criteria for Acceptability of Medical Radiology, Nuclear Medicine and Radiotherapy of the European Commission; the Protocols of Control de Calidad en Radiodiagnostico IAEA / ARCAL XLIX; and the Protocolo Espanol de Control de Calidad en Radiodignostico. The comparative analysis of these legislations was based on aspects of tolerance / limit, frequency and objectives of the recommended tests. Were found 18 tests in the Brazilian legislation. The tests were grouped according to their nature (dosimetric tests / exposure and geometric tests and image quality tests). Among the evaluated protocols was identified divergence between tests contained in the documents and the criteria of assessment set out in this work. It is clear, moreover, that for certain documents are not observed tolerances, well-defined methodologies and even frequency of testing. We conclude that the current legislation in Brazil differs in certain respects from international protocols analyzed, although this has a great numbers of quality control tests. However, it is necessary that the Brazilian legislation takes into account technological advances presented to time

    The number of Health Technology Assessment (HTA) agencies increases. One component of HTAs are economic aspects. To incorporate economic aspects commonly economic evaluations are performed. A convergence of recommendations for methods of health economic evaluations between international HTA agencies would facilitate the adaption of results to different settings and avoid unnecessary expense. A first step in this direction is a detailed analysis of existing similarities and differences in recommendations to identify potential for harmonization. The objective is to provide an overview and comparison of the methodological recommendations of international HTA agencies for economic evaluations. The webpages of 127 international HTA agencies were searched for guidelines containing recommendations on methods for the preparation of economic evaluations. Additionally, the HTA agencies were requested information on methods for economic evaluations. Recommendations of the included guidelines were extracted in standardized tables according to 13 methodological aspects. All process steps were performed independently by two reviewers. Finally 25 publications of 14 HTA agencies were included in the analysis. Methods for economic evaluations vary widely. The greatest accordance could be found for the type of analysis and comparator. Cost-utility-analyses or cost-effectiveness-analyses are recommended. The comparator should continuously be usual care. Again the greatest differences were shown in the recommendations on the measurement/sources of effects, discounting and in the analysis of sensitivity. The main difference regarding effects is the focus either on efficacy or effectiveness. Recommended discounting rates range from 1.5%-5% for effects and 3%-5% for costs whereby it is mostly recommended to use the same rate for costs and effects. With respect to the analysis of sensitivity the main difference is that oftentimes the probabilistic or deterministic approach is recommended

    Carbon dioxide embodied flow in international trade has become an important factor in defining global carbon emission responsibility and climate policy. We conducted an empirical analysis for China and Japan for the years 2000-2014, using a multi-region input-output model and considering the rest of the world as a comparison group. We compared the two countries' direct and complete carbon dioxide emissions intensity and bilateral economic activities such as imports and exports, production and consumption to analyze the difference between China and Japan. The results showed that the intensities of carbon emissions in all sectors of China were higher than that in Japan and that China's annual production-based emissions were greater than consumption-based emissions, the opposite of these relationships in Japan. China was a typical net carbon export country, and carbon embodied in its imports and exports continued to increase throughout the study period. In contrast, Japan's volume and growth rate of embodied carbon emissions were far less than China's and Japan was a typical net carbon import country. Finally, the conclusions of this study support recommendations for the formulation of international carbon emission responsibility allocation, domestic abatement policy as well as China's trade policy.

  13. Efficiency of international cooperation schemata in African countries: A comparative analysis using a data envelopment analysis approach

    Directory of Open Access Journals (Sweden)

    Victor Martin-Perez

    2017-02-01

    Full Text Available Background: Efficiency measurement by means of data envelopment analysis (DEA in the non-profit sector has focused on the so-called Stage I of non-profit organisations, namely, fundraising efforts (which are the most influential determinants of raising funds in order to increase the amount of contributions. However, for the so-called Stage II of non-profit organisations, namely, spending the achieved resources to program services delivery, DEA studies are very scarce. In attempting to address this research gap and to the best of our knowledge, this investigation is the first study that applies DEA to the assessment of international cooperation schemata. Consequently, we offer a significant contribution to the literature by overcoming the limitations of other techniques used to assess the efficiency and providing new insight into the efficiency of targeted different international cooperation schemata (ICS in international cooperation development projects. Aim: The purpose of this study is to evaluate and compare the efficiency of the ICS of developmental projects funded by the Spanish Agency for International Cooperation for Development. Setting: Our setting is composed of different international cooperation projects funded with different schemata by the Spanish Agency for International Cooperation for Development between 2002 and 2006 in two African countries that are top priority targets of Spanish international aid: Morocco, and Mozambique. Methods: Using a sample of 48 international cooperation projects carried out in two African countries considered priorities in the Spanish Cooperation Master Plan, we analyse project efficiency using DEA. Results: The findings suggest that some schemata are more efficient than others when applied to international cooperation projects (ICS. Specifically, we find that permanent open-call subsidies are more efficient than non-governmental development organisation subsidies. Conclusion: Measures for evaluating

    2017-01-01

    Full Text Available Objectives: Performance indicators are a popular mechanism for measuring the quality of healthcare to facilitate both quality improvement and systems management. Few studies make comparative assessments of different countries’ performance indicator frameworks. This study identifies and compares frameworks and performance indicators used in selected Organisation for Economic Co-operation and Development health systems to measure and report on the performance of healthcare organisations and local health systems. Countries involved are Australia, Canada, Denmark, England, the Netherlands, New Zealand, Scotland and the United States. Methods: Identification of comparable international indicators and analyses of their characteristics and of their broader national frameworks and contexts were undertaken. Two dimensions of indicators – that they are nationally consistent (used across the country rather than just regionally and locally relevant (measured and reported publicly at a local level, for example, a health service – were deemed important. Results: The most commonly used domains in performance frameworks were safety, effectiveness and access. The search found 401 indicators that fulfilled the ‘nationally consistent and locally relevant’ criteria. Of these, 45 indicators are reported in more than one country. Cardiovascular, surgery and mental health were the most frequently reported disease groups. Conclusion: These comparative data inform researchers and policymakers internationally when designing health performance frameworks and indicator sets.

  15. The ‘Landscape’ of Nuclear Safeguards: A Comparative Analysis of the International and Regional Systems

    International Nuclear Information System (INIS)

    Colussi, I.A.

    2015-01-01

    The notion of “nuclear non-proliferation” is twofold. It refers to: (a) reduction of the number of existing arsenals (vertical non-proliferation), and (b) containment of the number of States that possess nuclear weapons, or control of non-state actors (horizontal non-proliferation). At the international law level, as vertical non-proliferation, there are bilateral or multilateral agreements that ban weapons of mass destruction in certain areas (e.g.: Nuclear–Weapon– Free Zones treaties). With respect to horizontal non-proliferation, beyond the Nuclear-Weapon-Free Zones approach, the main legal text for addressing the issue is the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). For the implementation of the principles contained in the NPT, a “nuclear safeguards” system has been created, and the International Atomic Energy Agency (IAEA) has been assigned the role of the nuclear “watchdog” for the NPT. However, along with this international system of safeguards, there are regional safeguards bodies: (a) the European Atomic Energy Community (EURATOM) model is the cornerstone of non-proliferation in the EU, while (b) the Brazilian-Argentine Agency for Accounting for and Control of Nuclear Materials (ABACC) controls nuclear activities in Brazil and Argentina. Moreover, the existing nuclear weapons free-zone treaties contain safeguards provisions that are additional or complementary to IAEA safeguards. For instance, (a) the Agency for the Prohibition of Nuclear Weapons in Latin America and the Caribbean (OPANAL) works for the implementation of Tlatelolco Treaty, (b) the African Commission on Nuclear Energy relates to Pelindaba Treaty, and (c) a Consultative Committee of the Parties is appointed in the context of Raratonga Treaty. The paper aims at critically analysing the different safeguards systems adopted at the international and regional level, through the adoption of a comparative approach. (author)

    Dementia is a life-limiting condition that is increasing in global prevalence in line with population ageing. In this context, it is necessary to accurately measure dementia knowledge across a spectrum of health professional and lay populations with the aim of informing targeted educational interventions and improving literacy, care, and support. Building on prior exploratory analysis, which informed the development of the preliminarily valid and reliable version of the Dementia Knowledge Assessment Scale (DKAS), a Confirmatory Factor Analysis (CFA) was performed to affirm construct validity and proposed subscales to further increase the measure's utility for academics and educators. A large, de novo sample of 3649 volunteer respondents to a dementia-related online course was recruited to evaluate the performance of the DKAS and its proposed subscales. Respondents represented diverse cohorts, including health professionals, students, and members of the general public. Analyses included CFA (using structural equation modelling), measures of internal consistency (α), and non-parametric tests of subscale correlation (Spearman Correlation) and score differences between cohorts (Kruskal-Wallis one-way analysis of variance). Findings of the CFA supported a 25-item, four-factor model for the DKAS with two items removed due to poor performance and one item moved between factors. The resultant model exhibited good reliability (α = .85; ω h  = .87; overall scale), with acceptable subscale internal consistency (α ≥ .65; subscales). Subscales showed acceptable correlation without any indication of redundancy. Finally, total and DKAS subscale scores showed good discrimination between cohorts of respondents who would be anticipated to hold different levels of knowledge on the basis of education or experience related to dementia. The DKAS has been confirmed as a reliable and valid measure of dementia knowledge for diverse populations that is capable of elucidating

    2007-01-01

    Relations between various values of the internal friction (tgδ, Q -1 , Q -1* , and Λ/π) measured by free decay and forced vibration are analyzed systemically based on a fundamental mechanical model in this paper. Additionally, relations between various natural frequencies, such as vibration frequency of free decay ω FD , displacement-resonant frequency of forced vibration ω d , and velocity-resonant frequency of forced vibration ω 0 are calculated. Moreover, measurement of natural frequencies of a copper specimen of 99.9% purity has been made to demonstrate the relation between the measured natural frequencies of the system by forced vibration and free decay. These results are of importance for not only more accurate measurement of the elastic modulus of materials but also the data conversion between different internal friction measurements

    2017-05-01

    Full Text Available Few studies have investigated how the press covers political leaders’ deaths and the societal, cultural and political connotations of such coverage. Even fewer have tackled the topic when that leader is black. We use Framing Theory applied through an interpretive textual analysis to over 80 news articles from two South African and two Brazilian dailies to understand how Nelson Mandela—a black iconic leader—was framed in the 11 days straddling his death and death events. These two countries were selected, because South Africa was Mandela’s home, and Brazil has the largest Black population of any country outside of Africa. Additionally, both nations are locked in partnerships, including their participation in BRICS and IBSA. Comparing and contrasting seven emergent frames points to the need to consider the social construction of the collective memory of his death as pursuant to understanding Mandela’s legacy.   Até agora poucos estudos investigaram como a imprensa cobre a morte de líderes políticos, e as consequentes conotações sociais, culturais e políticas dessa cobertura. Ainda menos estudos abordam o tema quando se trata de um líder negro. Utilizamos a Teoria do Enquadramento, aplicada através de uma análise textual interpretativa a mais de 80 artigos de notícias de dois jornais sul-africanos e dois brasileiros para entendermos como Nelson Mandela - um líder icônico negro - foi enquadrado nos 11 dias entre sua morte e os eventos ao redor da mesma. Estes dois países foram selecionados, porque a África do Sul era a nação de Mandela, e o Brasil devido ao fato de ter a maior população negra de qualquer país além da África. Além disso, essas nações são parceiras já que fazem parte dos BRICS e IBSA. Ao compararmos e contrastarmos sete quadros emergentes dessa cobertura, apontamos para a necessidade de considerarmos a construção social da memória coletiva de sua morte como modo de compreendermos o legado da

  9. Comparative international analysis of radiofrequency exposure surveys of mobile communication radio base stations

    Science.gov (United States)

    Rowley, Jack T; Joyner, Ken H

    2012-01-01

    This paper presents analyses of data from surveys of radio base stations in 23 countries across five continents from the year 2000 onward and includes over 173,000 individual data points. The research compared the results of the national surveys, investigated chronological trends and compared exposures by technology. The key findings from this data are that irrespective of country, the year and cellular technology, exposures to radio signals at ground level were only a small fraction of the relevant human exposure standards. Importantly, there has been no significant increase in exposure levels since the widespread introduction of 3G mobile services, which should be reassuring for policy makers and negate the need for post-installation measurements at ground level for compliance purposes. There may be areas close to antennas where compliance levels could be exceeded. Future potential work includes extending the study to additional countries, development of cumulative exposure distributions and investigating the possibility of linking exposure measurements to population statistics to assess the distribution of exposure levels relative to population percentiles.

The key findings from this data are that irrespective of country, the year and cellular technology, exposures to radio signals at ground level were only a small fraction of the relevant human exposure standards. Importantly, there has been no significant increase in exposure levels since the widespread introduction of 3G mobile services, which should be reassuring for policy makers and negate the need for post-installation measurements at ground level for compliance purposes. There may be areas close to antennas where compliance levels could be exceeded. Future potential work includes extending the study to additional countries, development of cumulative exposure distributions and investigating the possibility of linking exposure measurements to population statistics to assess the distribution of exposure levels relative to population percentiles.

  11. Comparative Analysis of Miniature Internal Combustion Engine and Electric Motor for UAV Propulsion

    Science.gov (United States)

    Chiclana, Branden Mark

    This thesis compares the performance of an engine/fuel tank based propulsion system to a motor/battery based propulsion system of equal total mass. The results show that the endurance of the engine/fuel system at the same thrust output is approximately 5 times greater than that of the motor/battery system. This is a direct result of the fact that the specific energy of the fuel is 20 times that of the lithium-polymer batteries used to power the motor. A method is also developed to account for the additional benefits of fuel consumption (and hence weight reduction) over the course of the flight. Accounting for this effect can increase endurance exponentially. Taken together, the results also demonstrate the dramatic performance improvements that are possible simply by replacing motor/battery systems with engine/fuel systems on small unmanned air vehicles.

  12. Effectiveness and Internal Security. A Comparative Analysis of El Salvador and Nicaragua

    Full Text Available Nicaragua and El Salvador share many commonalities, including geographical vulnerabilities, widespread poverty, the experience of civil conflict in the 1980s, and a transition to democracy in the early 1990s. Nevertheless, each state has drastically divergent levels of violence, as measured particularly by homicide rates, with Nicaragua among the lowest in Latin America and El Salvador among the highest in the world. This paper assesses the historical and institutional variables that account for this divergence and evaluates each state’s security structures using a civil-military relations analysis. In particular, the author uses Bruneau and Matei’s criterion of effectiveness. The findings demonstrate that Nicaragua’s security forces consolidated during the 1980s in a manner more capable of sustaining the democratic transition and confronting new security threats like gangs and organized crime.

    Full Text Available Due mainly to the privatization and commercialization of airline companies and deregulation of the aviation rules, the demand for air transport has continuously been increasing. Airport authorities state that transfer passengers, who contribute to the large portion of the airports’ profits, are gaining much more importance, particularly in the Northeast Asia region where the air transport industry is very vital. Therefore, this study aims to investigate the competitiveness of IIA (Incheon International Airport with other major airports located in Northeast Asia in passenger transfers made between Southeast Asia and China to North America using Conjoint Analysis. Results have indicated that airport brand is the most important attribute for the competitiveness of airport, followed by cost, connectivity and duty free shops. In further analysis focusing on brand value of the three airports measured by the use of transfer passengers, it was revealed that IIA needs more effort in developing their brand identity to become the leading transfer hub airport. Based on the results, recommendations for increasing the brand value have also been suggested.

    The oil industry is one of the more global sectors of the economy, with its economic agents acting and competing at the same time in many countries. The limitation of available funds for investment and competition in global scale make the host countries adapt some elements of their concession instruments, as a way to attract greater investments. The comparison of legal framework of diverse host countries is an essential part in this process of decision and an indispensable tool to help the host countries in the dispute for the attraction of international investors. Therefore, to place Brazil in this process of global competition between States is necessary the knowledge and the comparison between the conditions offered for its legal system and offered for countries considered as models of attraction of investment. This work intends to offer a comparative study of relevant legal aspects for the oil industry, amongst them: characterization of the concession instrument; reach of the participation of the state-owned company; intervention of the State in the private management. The comparison will be made between countries with different characteristics, to obtain a consolidation of paradigms that helps the evolution of the Brazilian exploration and production legal framework.

    Sialoadhesin (Sn) is a surface receptor expressed on resident macrophages with the ability to bind with sialic acids. During inflammation, an upregulation of Sn is observed. Upon binding of monoclonal antibodies to Sn, the receptor becomes internalized and this has been observed in multiple species. The latter characteristic, combined with the strong upregulation of Sn on inflammatory macrophages and the fact that Sn-positive macrophages contribute to certain inflammatory diseases, makes Sn an interesting entry portal for phenotype-modulating or cytotoxic drugs. Such drugs or toxins can be linked to Sn-specific antibodies which should enable their targeted uptake by macrophages. However, the activity of such drugs depends not only on their internalization but also on the intracellular trafficking and final fate in the endolysosomal system. Although information is available for porcine Sn, the detailed mechanisms of human and mouse Sn internalization and subsequent intracellular trafficking are currently unknown. To allow development of Sn-targeted therapies, differences across species and cellular background need to be characterized in more detail. In the current report, we show that internalization of human and mouse Sn is dynamin-dependent and clathrin-mediated, both in primary macrophages and CHO cell lines expressing a recombinant Sn. In primary macrophages, internalized Sn-specific F(ab') 2 fragments are located mostly in the early endosomes. With Fc containing Sn-specific antibodies, there is a slight shift towards lysosomal localization in mouse macrophages, possibly because of an interaction with Fc receptors. Surprisingly, in CHO cell lines expressing Sn, there is a predominant lysosomal localization. Our results show that the mechanism of Sn internalization and intracellular trafficking is concurrent in the tested species. The cellular background in which Sn is expressed and the type of antibody used can affect the intracellular fate, which in turn can

    In the recent years the fuel cells have received much attention. Among various technologies, the Proton Exchange Membrane Fuel Cell (PEMFC) is currently the most appropriate and is used in several vehicles prototype. A comparative technical, economical and ecological analysis between an Internal Combustion Engine fueled with Diesel driving an electricity Generator (ICE-G) and a PEMFC fed by hydrogen produced by ethanol steam reforming was performed. The technical analysis showed the advantages of the PEMFC in comparison to the ICE-G based in energetic and exergetic aspects. The economic analysis shows that fuel cells are not economic competitive when compared to internal combustion engine driving an electricity generator with the same generation capacity; it will only be economically feasible in a long term; due to the large investments required. The environmental analysis was based on concepts of CO 2 equivalent, pollution indicator and ecological efficiency. Different to the ICE-G system, the Fuel Cell does not emit pollutants directly and the emission related to this technology is linked mainly with hydrogen production. The ecological efficiency of PEMFC was 96% considering the carbon dioxide cycle, for ICE-G system this parameter reach 51%. -- Highlights: • The exergetic efficiency of ICE-G was 22% and for the fuel cell was 40%. • The PEM fuel cell at long-term become economically competitive compared to ICE-G. • The ecological efficiency of PEM fuel cell was 96% and Diesel ICE-G was 51%

    2012-11-01

    Full Text Available The aim in this study is to analyze the current stage of conceptual convergence between Brazilian accounting standards applied to the public sector (NBCTSP and the International Public Sector Accounting Standard (IPSAS. The complexity and range of transactions between public or private sector entities, as a result of market internationalization, demand continuous and dynamic assessment of the events that promote quantitative or qualitative equity changes. For this evaluation process, observing accounting principles and standards is important to guarantee, among other information characteristics, understandability and comparability, thus reducing costs for investors and users in general, in view of the barriers raised by diverse languages, cultures, tax and economic policies. For convergence analysis, the standards’ contents were subject to a comparative study, based on a descriptive analysis, with a view to verifying the existing adherence between Brazilian and international standards applied to the public sector. The results found highlight that different aspects still have to be discussed with a view to an actual convergence with the international standards; the current convergence is partial. The high-quality conceptual exposure of the NBCPSPs is observed though, while the contents of the IPSAS are more focused on operating procedures

    Introduction We evaluated with transit time flow the performance of the right and left thoracic arteries when used as a graft for the left anterior descending artery. Methods Fifty patients undergoing surgery for myocardial revascularization without cardiopulmonary bypass were divided into two groups. In group A patients received graft of right internal mammary artery to the anterior interventricular branch. In group B patients received graft of left internal mammary artery to the same branch. At the end of the operation the flow was assessed by measuring transit time. Results In group A, mean age was 60.6±9.49 years. The average height and weight of the group was 80.4±10.32 kg and 169.2±6.86 cm. The average number of grafts per patient in this group was 3.28±1.49. The mean flow and distal resistance obtained in right internal thoracic artery was 42.1±23.4 ml/min and 2.8±0.9 respectively. In group B, the mean age was 59.8±9.7 years. The average height and weight of this group was 77.7±14.22 kg and 166.0±8.2 cm. The average number of grafts per patient in this group was 3.08 ±0.82. The mean flow and distal resistance observed in this group was 34.2±19.1 ml/min and 2.0±0.7. There were no deaths in this series. Conclusion Right internal mammary artery presented a similar behavior to left internal mammary artery when anastomosed to the anterior interventricular branch of the left coronary artery. There was no statistical difference between the measured flow obtained between both arteries. PMID:25140463

    Full Text Available Theme The situation analysis, as a separate component of the strategic planning, involves collecting and analysing relevant types of information on the components of the marketing environment and their evolution on the one hand and also on the organization’s resources and capabilities on the other. Objectives of the Research The main purpose of the study of the analysis techniques of the internal environment is to provide insight on those aspects that are of strategic importance to the organization. Literature Review The marketing environment consists of two distinct components, the internal environment that is made from specific variables within the organization and the external environment that is made from variables external to the organization. Although analysing the external environment is essential for corporate success, it is not enough unless it is backed by a detailed analysis of the internal environment of the organization. The internal environment includes all elements that are endogenous to the organization, which are influenced to a great extent and totally controlled by it. The study of the internal environment must answer all resource related questions, solve all resource management issues and represents the first step in drawing up the marketing strategy. Research Methodology The present paper accomplished a documentary study of the main techniques used for the analysis of the internal environment. Results The special literature emphasizes that the differences in performance from one organization to another is primarily dependant not on the differences between the fields of activity, but especially on the differences between the resources and capabilities and the ways these are capitalized on. The main methods of analysing the internal environment addressed in this paper are: the analysis of the organizational resources, the performance analysis, the value chain analysis and the functional analysis.

    To determine whether internal limiting membrane (ILM) peeling during pars plana vitrectomy for rhegmatogenous retinal detachment reduces the incidence of epiretinal membrane (ERM) formation. In this retrospective study, preoperative, intraoperative, and postoperative data from all eyes undergoing pars plana vitrectomy for rhegmatogenous retinal detachment between January 2007 and December 2013 was analyzed. All cases with at least 1-year of follow-up were included. Data collection included vision, intraoperative complications, occurrence of ERM, and spectral domain optical coherence tomography characteristics. The OCTs were retrieved for all eyes and were graded by a single masked grader. Out of 159 eyes recruited, ILM peeling was done in 78 eyes (49%). Overall occurrence of ERM was 20%. Seven eyes (9%) in ILM peeling group and 25 eyes in the non-ILM peeling group (31%) showed ERM (P = 0.001). Postoperative vision was significantly better in eyes that had ILM peeling (0.48 ± 0.4 logarithm of the minimum angle of resolution [20/63] vs. 0.77 ± 0.6 logarithm of the minimum angle of resolution [20/125], P = 0.003). In multivariable models adjusting for type of tamponade, ILM peeling reduced the likelihood of ERM formation by 75% (P = 0.01). Internal limiting membrane peeling during pars plana vitrectomy for rhegmatogenous retinal detachment significantly reduces ERM formation in the postoperative period and is associated with better visual and anatomical outcomes.

    Full Text Available This article compares sentencing of those convicted of participation in the 1994 genocide in Rwanda. With over one million people facing trial, Rwanda constitutes the world’s most comprehensive case of criminal accountability after genocide and presents an important case study of punishing genocide. Criminal courts at three different levels— international, domestic, and local—sought justice in the aftermath of the violence. In order to compare punishment at each level, we analyze an unprecedented database of sentences given by the ICTR, the Rwandan domestic courts, and Rwanda’s Gacaca courts. The analysis demonstrates that sentencing varied across the three levels—ranging from limited time in prison to death sentences. We likewise find that sentencing at the domestic courts appears to have been comparatively more serious than sentencing at the ICTR and at the Gacaca courts, which calls into question consistency of sentences across levels of justice and should be explored in future research.

    Population management (PM) initiatives are introduced in order to create sustainable health care systems. These initiatives should focus on the continuum of health and well-being of a population by introducing interventions that integrate various services. To be successful they should pursue the Triple Aim, i.e. simultaneously improve population health and quality of care while reducing costs per capita. This study explores how PM initiatives measure the Triple Aim in practice. An exploratory search was combined with expert consultations to identify relevant PM initiatives. These were analyzed based on general characteristics, utilized measures and related selection criteria. In total 865 measures were used by 20 PM initiatives. All quality of care domains were included by at least 11 PM initiatives, while most domains of population health and costs were included by less than 7 PM initiatives. Although their goals showed substantial overlap, the measures applied showed few similarities between PM initiatives and were predominantly selected based on local priority areas and data availability. Most PM initiatives do not measure the full scope of the Triple Aim. Additionally, variety between measures limits comparability between PM initiatives. Consensus on the coverage of Triple Aim domains and a set of standardized measures could further both the inclusion of the various domains as well as the comparability between PM initiatives.

    1988-01-01

    In this paper, the risks of various energy systems are discussed considering severe accidents analysis, particularly the probabilistic safety analysis, and probabilistic safety criteria, and the applications of these criteria and analysis. The comparative risk analysis has demonstrated that the largest source of risk in every society is from daily small accidents. Nevertheless, we have to be more concerned about severe accidents. The comparative risk analysis of five different energy systems (coal, oil, gas, LWR and STEC (Solar)) for the public has shown that the main sources of risks are coal and oil. The latest comparative risk study of various energy has been conducted in the USA and has revealed that the number of victims from coal is 42 as many than victims from nuclear. A study for severe accidents from hydro-dams in United States has estimated the probability of dam failures at 1 in 10,000 years and the number of victims between 11,000 and 260,000. The average occupational risk from coal is one fatal accident in 1,000 workers/year. The probabilistic safety analysis is a method that can be used to assess nuclear energy risks, and to analyze the severe accidents, and to model all possible accident sequences and consequences. The 'Fault tree' analysis is used to know the probability of failure of the different systems at each point of accident sequences and to calculate the probability of risks. After calculating the probability of failure, the criteria for judging the numerical results have to be developed, that is the quantitative and qualitative goals. To achieve these goals, several systems have been devised by various countries members of AIEA. The probabilistic safety ana-lysis method has been developed by establishing a computer program permit-ting to know different categories of safety related information. 19 tabs. (author)

    This report outlines the current state of standardised energy management systems (EnMSs) worldwide whose aim is to promote energy efficiency in the industrial sector. The core intention of the study is to identify the potential of EnMSs for German energy efficiency policy. The study examines the experiences of countries that can be defined as front runners in this context, such as the Netherlands, Denmark, Sweden, Ireland and the USA. Further input was taken from recently completed, and still ongoing, development processes of national standards. Data were generated from an intensive literature review as well as interviews with experts. Central to the analysis are questions of characteristics as well as the effectiveness of national energy management standards. In addition, political frameworks (i.e. voluntary agreements), financial tools (i.e. subsidies) and other measures of assistance (i.e. capacity building) supporting the implementation of an EnMS were analysed. The study concludes with a comparison of findings from the country-by-country analysis and provides recommendations for the effective implementation of EnMS in Germany. As part of the entire project adelphi produced a manual on the use of EN 16001 which has been published by BMU/UBA. (orig.)

    Destruction of health systems in fragile and conflict-affected states increases civilian mortality. Despite the size, scope, scale and political influence of international security forces intervening in fragile states, little attention has been paid to array of ways they may impact health systems beyond their effects on short-term humanitarian health aid delivery. Using case studies we published on international security forces' impacts on health systems in Haiti, Kosovo, Afghanistan and Libya, we conducted a comparative analysis that examined three questions: What aspects, or building blocks, of health systems did security forces impact across the cases and what was the nature of these impacts? What forums or mechanisms did international security forces use to interact with health system actors? What policies facilitated or hindered security forces from supporting health systems? We found international security forces impacted health system governance, information systems and indigenous health delivery organizations. Positive impacts included bolstering the authority, transparency and capability of health system leadership. Negative impacts included undermining the impartial nature of indigenous health institutions by using health projects to achieve security objectives. Interactions between security and health actors were primarily ad hoc, often to the detriment of health system support efforts. When international security forces were engaged in health system support activities, the most helpful communication and consultative mechanisms to manage their involvement were ones that could address a wide array of problems, were nimble enough to accommodate rapidly changing circumstances, leveraged the power of personal relationships, and were able to address the tensions that arose between security and health system supporting strategies. Policy barriers to international security organizations participating in health system support included lack of mandate, conflicts

    Full Text Available Over the last 10-20 years, comparative research in the feld of communication has almost become fashionable. Many factors are responsible for this, for example: an increased awareness of globalisation as a communication-driven process; an awareness of increased transnational conglomerization of media organizations; and the increasing use of the Internet which facilitates easier access to information around the world. But the big question is how to organize collaborative international communication research efectively? Which models of cooperation are available to us, and what are their advantages and disadvantages? In this article, I analyze fve ways of doing collaborative researches and their respective challenges.

    Full Text Available The aim of this study was to analyze the adoption of calculative and collaborative practices dominating comparative international human resources management, according to the different profiles of the areas of Human Resources Management (HRM of private organizations operating in Brazil. The method employed was a Survey, operated by means of an electronic questionnaire on HRM practices and organizational characteristics. A total of 326 respondents was obtained. Initially a cluster was conducted, in which respondents were clustered into four groups with different HRM profiles. The use of calculative and collaborative practices was compared in the four groups formed through the ANOVA (analysis of variance collection of statistical models. The main findings showed that the strategic group was the one with the highest average of adoption of calculative and collaborative practices. The Communicative HRM group showed a higher propensity to collaborative practices and the Formalized HRM group would adopt calculative practices, although none of the groups showed an average of adoption than the Strategic HRM group. This suggests that it is necessary to learn how to deal with different aspects of the management of people in organizations operating in Brazil.

    The continuous emergence of new strains of canine parvovirus (CPV), poorly protected by current vaccination, is a concern among breeders, veterinarians, and dog owners around the world. Therefore, the understanding of the genetic variation in emerging CPV strains is crucial for the design of disease control strategies, including vaccines. In this paper, we obtained the sequences of the full-length gene encoding for the main capsid protein (VP2) of 11 canine parvovirus type 2 (CPV-2) Argentine representative field strains, selected from a total of 75 positive samples studied in our laboratory in the last 9 years. A comparative sequence analysis was performed on 9 CPV-2c, one CPV-2a, and one CPV-2b Argentine strains with respect to international strains reported in the GenBank database. In agreement with previous reports, a high degree of identity was found among CPV-2c Argentine strains (99.6-100% and 99.7-100% at nucleotide and amino acid levels, respectively). However, the appearance of a new substitution in the 440 position (T440A) in four CPV-2c Argentine strains obtained after the year 2009 gives support to the variability observed for this position located within the VP2, three-fold spike. This is the first report on the genetic characterization of the full-length VP2 gene of emerging CPV strains in South America and shows that all the Argentine CPV-2c isolates cluster together with European and North American CPV-2c strains.

  3. EPR compared to international requirements (Mainly EUR)

    1996-01-01

    A number of European Utilities have entered an agreement to write common requirements dedicated to future light water nuclear power plants to be built in Europe. The activities are known under the sign EUR (European Utilities Requirements). EPR, the future European Pressurized water Reactor, is the first installation of this type which will be operational from the year 2000 onwards, must fulfill the European requirements. EPR will serve as a test whether these requirements are realistic and well balanced. At the basic design stage of EPR, this paper concentrates on four main topics: the requirements which are new compared with existing reactors and which put a major challenge to the designer; the requirements today still open and the way they can be met by the EPR or not; the points for which already today the EPR special requirements exceed the EUR; the examples where the design of the EPR has given feedback which has led to a change of the EUR. EPR and EUR are different approaches to the reactor of the future. EUR is a set of requirements which leaves a flexibility to the designer while EPR is a real project which defines the technical solutions. EPR will fulfill the EUR and will at the same time serve as a test whether these requirements are realistic. EPR will also fulfill international requirements with minor changes. (J.S.). 7 figs

    The Cognitive Emotion Regulation Questionnaire (CERQ) is a cognitive and emotional tool measuring how individuals deal with stressful life events. However differences exist in the results of CERQ among individuals. This study was conducted to investigate the CERQ results and depressive symptoms of students at our university (both local and international students) in order to provide further guidance for psychological interventions. 255 sophomore and junior international students (171 male and 84 female) and 262 sophomore and junior Chinese students (124 male and 138 female) were investigated using CERQ, ASLEC and SDS questionnaires. Results were analyzed using SPSS 16.0. Compared to Chinese students, international students more often used cognitive adjustment methods such as "positive refocusing","re-focus on planning" and "catastrophizing". In regression equations where depression symptoms were used as the dependent variable, "self-blaming" and "catastrophizing"positively contributed to depression symptoms in international students, while"acceptance" was negatively correlated with depression symptoms.In Chinese students, "life events score" and "catastrophizing"were positively correlated withdepression symptoms, while "positive re-evaluating" was negatively correlated with depression symptoms. Among students of different races, positive coping methods were negatively correlated with depression symptoms and could possibly prevent the occurrence of depression, while negative coping methods were positively correlated with depression.Encouraging students to use adaptive coping methods during psychological intervention is an effective way to adjust cognitions and behavior for depression prevention.

    This study compared the conceptual foci and methodological characteristics of research projects which tested the effects of nursing interventions, published in four general nursing research journals with predominantly North American, and two with predominantly European/International authorship and readership. Dimensions and variables of comparison included: nature of subjects, design issues, statistical methodology, statistical power, and types of interventions and outcomes. Although some differences emerged, the most striking and consistent finding was that there were no statistically significant differences (and thus similarities) in the content foci and methodological parameters of the intervention studies published in both groups of journals. We conclude that European/International and North American nursing intervention studies, as reported in major general nursing research journals, are highly similar in the parameters studied, yet in need of overall improvement. Certainly, there is no empirical support for the common (explicit or implicit) ethnocentric American bias that leadership in nursing intervention research resides with and in the United States of America.

  6. Comparing the International Knowledge Flow of China’s Wind and Solar Photovoltaic (PV Industries: Patent Analysis and Implications for Sustainable Development

    Full Text Available Climate-relevant technologies, like wind and solar energy, are crucial for mitigating climate change and for achieving sustainable development. Recent literature argues that Chinese solar firms play more active roles in international knowledge flows, which may better explain their success in international markets when compared to those of Chinese wind firms; however, empirical evidence remains sparse. This study aims to explore to what extent and how do the international knowledge flows differ between China’s wind and solar photovoltaic (PV industries? From a network perspective, this paper develops a three-dimensional framework to compare the knowledge flows in both explicit and tacit dimensions: (i inter-country explicit knowledge clusters (by topological clustering of patent citation network; (ii inter-firm explicit knowledge flow (patent citation network of key firms; and, (iii inter-firm tacit knowledge flow (by desktop research and interviews. The results show that China’s PV industry has stronger international knowledge linkages in terms of knowledge clustering and explicit knowledge flow, but the wind power industry has a stronger tacit knowledge flow. Further, this study argues that the differences of global knowledge links between China’s wind and solar PV industries may be caused by technology characteristics, market orientation, and policy implementation. This suggests that these industries both have strong connections to global knowledge networks, but they may involve disparate catch-up pathways that concern follower-modes and leader-modes. These findings are important to help us understand how China can follow sustainable development pathways in the light of climate change.

    Interpretation of the growing body of global literature on health care risk is compromised by a lack of common understanding and language. This series of articles aims to comprehensively compare laws and regulations, institutional management, and administration of incidence reporting systems on medical risk management in the United Kingdom, the United States, Canada, Australia, and Taiwan, so as to provide evidence and recommendations for health care risk management policy in China. We searched the official websites of the healthcare risk management agencies of the four countries and one district for laws, regulatory documents, research reports, reviews and evaluation forms concerned with healthcare risk management and assessment. Descriptive comparative analysis was performed on relevant documents. A total of 146 documents were included in this study, including 2 laws (1.4%), 17 policy documents (11.6%), 41 guidance documents (28.1%), 37 reviews (25.3%), and 49 documents giving general information (33.6%). The United States government implemented one law and one rule of patient safety management, while the United Kingdom and Australia each issued professional guidances on patient safety improvement. The four countries implemented patient safety management policy on four different levels: national, state/province, hospital, and non-governmental organization. The four countries and one district adopted four levels of patient safety management, and the administration modes can be divided into an "NGO-led mode" represented by the United States and Canada and a "government-led mode" represented by the United Kingdom, Australia, and Taiwan. © 2011 Blackwell Publishing Asia Pty Ltd and Chinese Cochrane Center, West China Hospital of Sichuan University.

    Full Text Available Staphylococcus aureus is a human pathogen that can cause a wide range of diseases. Although formerly regarded as extracellular pathogen, it has been shown that S. aureus can also be internalized by host cells and persist within these cells. In the present study, we comparatively analyzed survival and physiological adaptation of S. aureus HG001 after internalization by two human lung epithelial cell lines (S9 and A549, and human embryonic kidney cells (HEK 293. Combining enrichment of bacteria from host-pathogen assays by cell sorting and quantitation of the pathogen´s proteome by mass spectrometry we characterized S. aureus adaptation during the initial phase between 2.5 h and 6.5 h post-infection. Starting with about 2x106 bacteria, roughly 1,450 S. aureus proteins, including virulence factors and metabolic enzymes were identified by spectral comparison and classical database searches. Most of the bacterial adaptation reactions, such as decreases in levels of ribosomal proteins and metabolic enzymes or increases in amounts of proteins involved in arginine and lysine biosynthesis, coding for terminal oxidases and stress responsive genes or activation of the sigma factor SigB were observed after internalization into any of the three cell lines studied. However, differences were noted in central carbon metabolism including regulation of fermentation and threonine degradation. Since these differences coincided with different intracellular growth behavior, complementary profiling of the metabolome of the different non-infected host cell types was performed. This revealed similar levels of intracellular glucose but host cell specific differences in the amounts of amino acids such as glycine, threonine or glutamate. With this comparative study we provide an impression of the common and specific features of the adaptation of S. aureus HG001 to specific host cell environments as a starting point for follow-up studies with different strain isolates and

    Why do governments pursue obesity legislation? And is the case of Brazil unique compared with other nations when considering the politics of policy reform? Using a nested analytic approach to comparative research, I found that theoretical frameworks accounting for why nations implement obesity legislation were not supported with cross-national statistical evidence. I then turned to the case of Brazil's response to obesity at three levels of government, national, urban, and rural, to propose alternative hypotheses for why nations pursue obesity policy. The case of Brazil suggests that the reasons that governments respond are different at these three levels. International forces, historical institutions, and social health movements were factors that prompted national government responses. At the urban and rural government levels, receiving federal financial assistance and human resource support appeared to be more important. The case of Brazil suggests that the international and domestic politics of responding to obesity are highly complex and that national and subnational political actors have different perceptions and interests when pursuing obesity legislation.

    The paper analyses the extent to which RPBF allocation mechanisms are being implemented in Europe. To do so, this study builds on a novel set of data on project and organisational level funding developed for the European Commission, which identifies funding allocation mechanisms in each of the EU-28 Member States. This approach allows to compare the scope of RPBF systems across European countries.Further, the paper build on an in-depth analysis of RPBF implementation in 28 European countries, which comes to a classification of different types of RPBF implementation around three characteristics, i.e. a) the way research performance is measured and b) the type of link between performance assessment and allocation of resources. The analysis furthermore identifies a number of good practices while highlighting the potential for adverse effects of RPBF systems in research systems at different stages of development. (Author)

    Ethical behaviour consists ofindividual choices inspired by knowledge and professional experience derived from the universally acknowledged ethical principles of beneficience/nonmaleficience, autonomy and justice. However, in spite of the unanimous consent on their universal importance, such principles do not usually have the strength of a law. The recently introduced Italian law on the protection of workers' health represents a novelty because it gives the Ethics Code of the International Commission on Occupational Health legal strength. This paper aims at examining article 25 of legislative decree 81/2008 by comparing the points of the Ethics Code and the Deontology Code of the Italian medical profession. The relationships between the 12 points of paragraph 1 of article 25, the 26 points ofthe Code ofEthics and the 75 articles of the Deontology Code are described with regard to the occupational health physician's duties (i) of collaboration with other occupational health professionals, (ii) of organization and execution of health surveillance, (iii) of recording, securing, transmitting of medical files on workers' health and (iv) of employee and employer information on the importance and meaning of health surveillance.

    A sediment reference material (S-37) was prepared as analytical quality control material to be used within an international project on polychlorinated hydrocarbon analysis in two Chinese rivers. The raw material was sampled during a cruise on Yangtse River and transported afterwards to the JRC Ispra for further processing. The material was treated according to the general principles applicable for candidate reference material production. After a thorough homogeneity study of the bulk the material was bottled. A total of 1,080 bottles each containing 50 g of dry sediment powder was obtained. Final homogeneity and stability testing proved the material to be fit for the purpose. Isotope dilution GC/MS was used to establish target values for pentachlorobenzene (1.17 +/- 0.08 ng/g), hexachlorobenzene (3.60 +/- 0.17 ng/g), octachlorostyrene (0.19 +/- 0.01 ng/g), pentachloroanisole (0.52 +/- 0.02 ng/g), alpha-HCH (0.70 +/- 0.05 ng/g), beta-HCH (1.38 +/- 0.18 ng/g), gamma-HCH (0.83 +/- 038 ng/g), 2,4'-DDT (0.36 +/- 0.04 ng/g), 2,4'-DDE (0.29 +/- 0.02 ng/g), 2,4'-DDD (0.49 +/- 0.02), 4,4'-DDT (3.42 +/- 0.47 ng/g), 4,4'-DDD (1.29 +/- 0.17 ng/g), PCB 28 (0.11 +/- 0.01 ng/g), PCB 52 (0.09 +/- 0.003 ng/g), PCB 101 (0.07 +/- 0.003 ng/g), PCB 138 (0.06 +/- 0.003 ng/g) and PCB 153 (0.06 +/- 0.003 ng/g). Furthermore, indicative values for major and minor constituents as well as for polychlorinated dibenzodioxines and -furanes were measured.

    Preclinical evaluation of the mechanical reliability of fixation devices is a mandatory activity before their introduction into market. There are two standardized protocols for preclinical testing of spinal implants. The American Society for Testing Materials (ASTM) recommends the F1717 standard, which describes a vertebrectomy condition that is relatively simple to implement, whereas the International Organization for Standardization (ISO) suggests the 12189 standard, which describes a more complex physiological anterior support-based setup. Moreover, ASTM F1717 is nowadays well established, whereas ISO 12189 has received little attention: A few studies tried to accurately describe the ISO experimental procedure through numeric models, but these studies totally neglect the recommended precompression step. This study aimed to build up a reliable, validated numeric model capable of describing the stress on the rods of a spinal fixator assembled according to ISO 12189 standard procedure. Such a model would more adequately represent the in vitro testing condition. This study used finite element (FE) simulations and experimental validation testing. An FE model of the ISO setup was built to calculate the stress on the rods. Simulation was validated by comparison with experimental strain gauges measurements. The same fixator has been previously virtually mounted in an L2-L4 FE model of the lumbar spine, and stresses in the rods were calculated when the spine was subjected to physiological forces and moments. The comparison between the FE predictions and experimental measurements is in good agreement, thus confirming the suitability of the FE method to evaluate the stresses in the device. The initial precompression induces a significant extension of the assembled construct. As the applied load increases, the initial extension is gradually compensated, so that at peak load the rods are bent in flexion: The final stress value predicted is thus reduced to about 50%, if

    Sex trafficking, trafficking for the purpose of forced sexual exploitation, is a widespread form of human trafficking that occurs in all regions of the world, affects mostly women and girls, and has far-reaching health implications. Studies suggest that up to 50 % of sex trafficking victims in the USA seek medical attention while in their trafficking situation, yet it is unclear how the healthcare system responds to the needs of victims of sex trafficking. To understand the intersection of sex trafficking and public health, we performed in-depth qualitative interviews among 277 antitrafficking stakeholders across eight metropolitan areas in five countries to examine the local context of sex trafficking. We sought to gain a new perspective on this form of gender-based violence from those who have a unique vantage point and intimate knowledge of push-and-pull factors, victim health needs, current available resources and practices in the health system, and barriers to care. Through comparative analysis across these contexts, we found that multiple sociocultural and economic factors facilitate sex trafficking, including child sexual abuse, the objectification of women and girls, and lack of income. Although there are numerous physical and psychological health problems associated with sex trafficking, health services for victims are patchy and poorly coordinated, particularly in the realm of mental health. Various factors function as barriers to a greater health response, including low awareness of sex trafficking and attitudinal biases among health workers. A more comprehensive and coordinated health system response to sex trafficking may help alleviate its devastating effects on vulnerable women and girls. There are numerous opportunities for local health systems to engage in antitrafficking efforts while partnering across sectors with relevant stakeholders.

    An extensive database has been assembled that contains the three most widely used sets of calculated internal conversion coefficients (ICC): [Hager R.S., Seltzer E.C., 1968. Internal conversion tables. K-, L-, M-shell Conversion coefficients for Z=30 to Z=103, Nucl. Data Tables A4, 1-237; Band I.M., Trzhaskovskaya M.B., 1978. Tables of gamma-ray internal conversion coefficients for the K-, L- and M-shells, 10≤Z≤104, Special Report of Leningrad Nuclear Physics Institute; Roesel F., Fries H.M., Alder K., Pauli H.C., 1978. Internal conversion coefficients for all atomic shells, At. Data Nucl. Data Tables 21, 91-289] and also includes new Dirac-Fock calculations [Band I.M. and Trzhaskovskaya M.B., 1993. Internal conversion coefficients for low-energy nuclear transitions, At. Data Nucl. Data Tables 55, 43-61]. This database is linked to a computer program to plot ICCs and their combinations (sums and ratios) as a function of Z and energy, as well as relative deviations of ICC or their combinations for any pair of tabulated data. Examples of these analyses are presented for the K-shell and total ICCs of the gamma-ray standards [Hansen H.H., 1985. Evaluation of K-shell and total internal conversion coefficients for some selected nuclear transitions, Eur. Appl. Res. Rept. Nucl. Sci. Tech. 11.6 (4) 777-816] and for the K-shell and total ICCs of high multipolarity transitions (total, K-, L-, M-shells of E3 and M3 and K-shell of M4). Experimental data sets are also compared with the theoretical values of these specific calculations

    We empirically examine the reporting on biotechnology in Kenyan and international newspapers between 2010 and early 2014. We identify news articles that reported on biotechnology and analyze their use of words to determine whether there is a balance in the reporting of perceived risks and benefits. We also consider how the sources used in news articles and how the publication of the Séralini study of rats fed genetically modified maize affect the balance of reporting of perceived risks and benefits. We find that in Kenyan news reporting, more articles mention perceived benefits than risks, but when risks are mentioned, new articles contain more references to risks than to benefits. We also find that sources affect the reporting of perceived risks and benefits and that the Séralini study increased the likelihood that perceived risks are reported in Kenyan news reporting, but not in international newspapers. © The Author(s) 2015.

    2014-07-01

    The objective of this study is to perform a comparative analysis between the Brazilian legislation and internationals protocols, with respect to the quality control tests for computerized tomography. We used 07 references, published from 1998-2012: the Protocolo Brasileiro - Portaria 453/98 SVS/MS and the Guia de Radiodiagnostico Medico da ANVISA; Quality Assurance Programme for Computed Tomography: Diagnostic and Therapy Applications of the IAEA; European Protocol - European Guidelines on Quality Criteria for Computed Tomography of the EUR No. 16262 EN; Radiation Protection No. 162 - Criteria for Acceptability of Medical Radiology, Nuclear Medicine and Radiotherapy of the European Commission; the Protocols of Control de Calidad en Radiodiagnostico IAEA / ARCAL XLIX; and the Protocolo Espanol de Control de Calidad en Radiodignostico. The comparative analysis of these legislations was based on aspects of tolerance / limit, frequency and objectives of the recommended tests. Were found 18 tests in the Brazilian legislation. The tests were grouped according to their nature (dosimetric tests / exposure and geometric tests and image quality tests). Among the evaluated protocols was identified divergence between tests contained in the documents and the criteria of assessment set out in this work. It is clear, moreover, that for certain documents are not observed tolerances, well-defined methodologies and even frequency of testing. We conclude that the current legislation in Brazil differs in certain respects from international protocols analyzed, although this has a great numbers of quality control tests. However, it is necessary that the Brazilian legislation takes into account technological advances presented to time.

    Comparative analysis of the methodologies was performed based on the discussions in the international workshop on 'Assessment Methodology of Proliferation Resistance for Future Nuclear Energy Systems' held in Tokyo, on March 2005. Through the workshop and succeeding considerations, it is clarified that the proliferation resistance assessment methodologies are affected by the broader nuclear options being pursued and also by the political situations of the state. Even the definition of proliferation resistance, despite the commonality of fundamental issues, derives from perceived threat and implementation circumstances inherent to the larger programs. Deep recognitions of the 'difference' among communities would help us to make further essential and progressed discussion with harmonization. (author)

    Ryakhovskiy, A N; Kostyukova, V V

    The aim of the study was to compare accuracy of digital impression's finishing line and the zone under it taken by different intraoral scanning systems. Parameters of comparison were: different level of the finishing line to the gingiva and width of sulcus after retraction. For this purpose two synthetic jaw models with prepared teeth were scanned using intraoral scanning systems: 3D Progress (MHT S.P.A., IT - MHT Optic Research AG, CH); True Definition (3M ESPE, USA); Trios (3Shape A/S, DNK); CEREC AC Bluecam, CEREC Omnicam (Sirona Dental System GmbH, DE); Planscan (Planmeca, FIN) (each n=10). Reference-scanning was done by ATOS Core (GOM mbH, DE). The resulting digital impressions were superimposed with the master-scan. The lowest measured deviations (trueness) for intraoral scanners, where the finishing line was 0.5 mm above gingiva were with scanner True Definition - 18.8±6.63 (on the finishing line) and 51.0±14.33 µm (0.3 mm under the finishing line). In conditions where finishing line was on the same level with gingiva, scanner Trios showed the best results: 17.0±3.96 and 52.7±6.52 µm. When the finishing line was 0.5 mm under gingiva, none of the testing scanners could visualize the zone 0.3 mm lower the finishing line. The best results for accuracy o the finishing line in that circumstances showed Trios: 15.1±5.05 µm. The optimum visualization of the finishing line and the zone under it was reached when the sulcus was 0.3 mm after retraction. Thus, the best accuracy was obtained with Trios: 10.3±2.69 (on the finishing line) and 57.2±13.58 µm (0.3 mm under finishing line). The results show that intraoral scanners also provide enough accuracy for indicating finishing line and the zone under it in different conditions of preparation and gingiva retraction. However, not all of the testing scanners can properly indicate finishing line and the zone under it when shoulder is below gingiva and the width of sulcus is less than 0.2 mm.

    2017-05-01

    Full Text Available The aim of this paper is to map this place of economics in the field of study of Comparative and International Education. Interrelationship between economy and education is concerned, two broad lines of enquiry lie within the scope of Comparative and International Education: economy as shaping force of education systems and the effect of education on the economy. In the interwar “factors and forces” stage of Comparative Education, the economy as a shaping force of national education systems came to the fore. In the social science phase of the 1960s the focus shifted to a study of the effect of education on the economy. This was reversed again in the 1970s, when socio-economic reproduction theories assigned a deterministic place to socio-economic stratification of society. In recent years neo-liberal economics dictated the research agenda of Comparative Education. In conclusion recommendations for a future research agenda in the field are made.

    This paper summarizes the on-orbit structural dynamic data and the related modal analysis, model validation and correlation performed for the International Space Station (ISS) configuration ISS Stage ULF7, 2015 Dedicated Thruster Firing (DTF). The objective of this analysis is to validate and correlate the analytical models used to calculate the ISS internal dynamic loads and compare the 2015 DTF with previous tests. During the ISS configurations under consideration, on-orbit dynamic measurements were collected using the three main ISS instrumentation systems; Internal Wireless Instrumentation System (IWIS), External Wireless Instrumentation System (EWIS) and the Structural Dynamic Measurement System (SDMS). The measurements were recorded during several nominal on-orbit DTF tests on August 18, 2015. Experimental modal analyses were performed on the measured data to extract modal parameters including frequency, damping, and mode shape information. Correlation and comparisons between test and analytical frequencies and mode shapes were performed to assess the accuracy of the analytical models for the configurations under consideration. These mode shapes were also compared to earlier tests. Based on the frequency comparisons, the accuracy of the mathematical models is assessed and model refinement recommendations are given. In particular, results of the first fundamental mode will be discussed, nonlinear results will be shown, and accelerometer placement will be assessed.

    2007-01-01

    The book gives an introduction to p-adic numbers from the point of view of number theory, topology, and analysis. Compared to other books on the subject, its novelty is both a particularly balanced approach to these three points of view and an emphasis on topics accessible to undergraduates. In addition, several topics from real analysis and elementary topology which are not usually covered in undergraduate courses (totally disconnected spaces and Cantor sets, points of discontinuity of maps and the Baire Category Theorem, surjectivity of isometries of compact metric spaces) are also included in the book. They will enhance the reader's understanding of real analysis and intertwine the real and p-adic contexts of the book. The book is based on an advanced undergraduate course given by the author. The choice of the topic was motivated by the internal beauty of the subject of p-adic analysis, an unusual one in the undergraduate curriculum, and abundant opportunities to compare it with its much more familiar real...

  5. Sociological analysis and comparative education

    Science.gov (United States)

    Woock, Roger R.

    1981-12-01

    It is argued that comparative education is essentially a derivative field of study, in that it borrows theories and methods from academic disciplines. After a brief humanistic phase, in which history and philosophy were central for comparative education, sociology became an important source. In the mid-50's and 60's, sociology in the United States was characterised by Structural Functionalism as a theory, and Social Survey as a dominant methodology. Both were incorporated into the development of comparative education. Increasingly in the 70's, and certainly today, the new developments in sociology are characterised by an attack on Positivism, which is seen as the philosophical position underlying both functionalism and survey methods. New or re-discovered theories with their attendant methodologies included Marxism, Phenomenological Sociology, Critical Theory, and Historical Social Science. The current relationship between comparative education and social science is one of uncertainty, but since social science is seen to be returning to its European roots, the hope is held out for the development of an integrated social theory and method which will provide a much stronger basis for developments in comparative education.

    Full Text Available Members of the genus Acinetobacter are ubiquitous in the environment and the multiple-drug resistant species A. baumannii is of significant clinical concern. This clinical relevance is currently driving research on bacterial viruses infecting A. baumannii, in an effort to implement phage therapy and phage-derived antimicrobials. Initially, a total of 42 Acinetobacter phage genome sequences were available in the international nucleotide sequence databases, corresponding to a total of 2.87 Mbp of sequence information and representing all three families of the order Caudovirales and a single member of the Leviviridae. A comparative bioinformatics analysis of 37 Acinetobacter phages revealed that they form six discrete clusters and two singletons based on genomic organisation and nucleotide sequence identity. The assignment of these phages to clusters was further supported by proteomic relationships established using OrthoMCL. The 4067 proteins encoded by the 37 phage genomes formed 737 groups and 974 orphans. Notably, over half of the proteins encoded by the Acinetobacter phages are of unknown function. The comparative analysis and clustering presented enables an updated taxonomic framing of these clades.

    The purpose of this internal hazards analysis is to identify and document the internal hazards and potential initiating events associated with preclosure operations of the repository at Yucca Mountain. Internal hazards are those hazards presented by the operation of the facility and by its associated processes that can potentially lead to a radioactive release or cause a radiological hazard. In contrast to external hazards, internal hazards do not involve natural phenomena and external man-made hazards. This internal hazards analysis was performed in support of the preclosure safety analysis and the License Application for the Yucca Mountain Project. The methodology for this analysis provides a systematic means to identify internal hazards and potential initiating events that may result in a radiological hazard or radiological release during the repository preclosure period. These hazards are documented in tables of potential internal hazards and potential initiating events (Section 6.6) for input to the repository event sequence categorization process. The results of this analysis will undergo further screening and analysis based on the criteria that apply to the performance of event sequence analyses for the repository preclosure period. The evolving design of the repository will be re-evaluated periodically to ensure that internal hazards that have not been previously evaluated are identified.

In doing so, a critique of the international transfer of globally dominant research modalities and strategies is presented--along with arguments for increased attention to context sensitivity in both international development cooperation and educational research in general. Illustrative examples that support these arguments are drawn from the author's own research, from an analysis of emergent educational policy debates in the UK, and from related studies being carried out in Malaysia. In concluding, the strategic role of comparative research traditions and perspectives in a rapidly globalizing world is highlighted, while supporting the promotion of new initiative and research centres for comparative and international education.

  13. RENT CONTROL: A COMPARATIVE ANALYSIS

    Directory of Open Access Journals (Sweden)

    Full Text Available Recent case law shows that vulnerable, previously disadvantaged private sector tenants are currently facing eviction orders – and consequential homelessness – on the basis that their leases have expired. In terms of the case law it is evident that once their leases have expired, these households do not have access to alternative accommodation. In terms of the Constitution, this group of marginalised tenants have a constitutional right of access to adequate housing and a right to occupy land with legally secure tenure. The purpose of this article is to critically analyse a number of legislative interventions, and specifically rent control, that were imposed in various jurisdictions in order to provide strengthened tenure protection for tenants. The rationale for this analysis is to determine whether the current South African landlord-tenant regime is able to provide adequate tenure protection for vulnerable tenants and therefore in the process of transforming in line with the Constitution. The legal construction of rent control was adopted in pre-1994 South Africa, England and New York City to provide substantive tenure protection for tenants during housing shortages. These statutory interventions in the different private rental markets were justified on the basis that there was a general need to protect tenants against exploitation by landlords. However, the justification for the persistent imposition of rent control in New York City is different since it protects a minority group of financially weak tenants against homelessness. The English landlord-tenant regime highlights the importance of a well-structured social sector that can provide secure, long-term housing options for low-income households who are struggling to access the private rental sector. Additionally, the English rental housing framework shows that if the social sector is functioning as a "safety net" for low-income households, the private sector would be able to uphold

    Elander, James; Beach, Mary Catherine; Haywood, Carlton

    2011-01-01

    Background/objectives Qualitative interview studies suggest that adult patients’ experiences of hospital treatment for sickle cell disease (SCD) pain reflect an absence of respect by providers for patients, and an absence or breakdown of trust. Systematic comparisons between treatment settings could help identify contextual influences on respect and trust. Design Quantitative comparison of concern-raising behaviors (pain treatment outcomes indicating breakdowns of trust) among adult SCD patients in Baltimore, Maryland, USA, and London, UK, followed by analysis of potential explanations for differences, including socio-cultural and behavioral factors, with a preliminary model of the processes leading to concern-raising behaviors. Results Rates of concern-raising behaviors were significantly higher in Baltimore than London. The model identifies respect and trust as key factors which could be targeted in efforts to improve the quality of SCD pain management in hospital. Conclusion An agenda for international, interdisciplinary research to improve the treatment of SCD pain in hospital should include: comparative analyses between countries and treatment settings of factors that could influence respect and trust; research to test hypotheses derived from models about the roles of respect and trust in the treatment of pain; studies of the impact of healthcare structures and policy on patients’ experiences of care; research focusing on developmental and interpersonal processes related to respect and trust; applications of attribution and other social psychology theories; and development and evaluation of interventions to improve the hospital treatment of SCD pain by increasing respect and trust.

    Hendrie, Hugh C

    2006-06-01

    International and crosscultural comparative studies of Alzheimer disease (AD) offer significant advantages in elucidating risk factors for the disease by providing a wider diversity of environmental exposures as well as greater genetic diversity than do studies confined to a single ethnic group in a developed country. They also present with major methodological problems. The problems and their possible solutions are discussed in this article by describing three projects involving the Cree and English-speaking residents of Manitoba, blacks from Indianapolis, Indiana, and Yoruba from Ibadan and residents of Chinese villages. In this review, the development and harmonization of a culture fair screening instrument for dementia, the CSID, is described. The advantage of a scientific paradigm that can incorporate genetic and environmental factors as well as their interactions to explore the etiology of AD is presented. The importance of developing strategies for recruitment and retention in international community-based studies is emphasized as is the necessity of establishing academic partnerships between the countries. The unique opportunity provided by geopolitical and sociocultural influences to study environmental exposures is exemplified by the ongoing study of the influence of selenium levels on cognition in Chinese villagers. Results from the Indianapolis, Indiana-Ibadan dementia project are presented suggesting that the incidence of AD is lower in Yoruba than in blacks and that this lower rate may be the result of a combination of genetic and environmental factors.

  3. Smoothing internal migration age profiles for comparative research

    Directory of Open Access Journals (Sweden)

    Aude Bernard

    2015-05-01

    Full Text Available Background: Age patterns are a key dimension to compare migration between countries and over time. Comparative metrics can be reliably computed only if data capture the underlying age distribution of migration. Model schedules, the prevailing smoothing method, fit a composite exponential function, but are sensitive to function selection and initial parameter setting. Although non-parametric alternatives exist, their performance is yet to be established. Objective: We compare cubic splines and kernel regressions against model schedules by assessingwhich method provides an accurate representation of the age profile and best performs on metrics for comparing aggregate age patterns. Methods: We use full population microdata for Chile to perform 1,000 Monte-Carlo simulations for nine sample sizes and two spatial scales. We use residual and graphic analysis to assess model performance on the age and intensity at which migration peaks and the evolution of migration age patterns. Results: Model schedules generate a better fit when (1 the expected distribution of the age profile is known a priori, (2 the pre-determined shape of the model schedule adequately describes the true age distribution, and (3 the component curves and initial parameter values can be correctly set. When any of these conditions is not met, kernel regressions and cubic splines offer more reliable alternatives. Conclusions: Smoothing models should be selected according to research aims, age profile characteristics, and sample size. Kernel regressions and cubic splines enable a precise representation of aggregate migration age profiles for most sample sizes, without requiring parameter setting or imposing a pre-determined distribution, and therefore facilitate objective comparison.

    Over 200 volunteers were recruited through Newspaper advertisements and other means to measure the BMD of the Lumbar Spine, Femoral Neck and Whole Body of normal healthy Canadians from the Toronto Area. All these people were carefully interviewed by trained scientists or medical personnel with respect to their medical history, life style and habits. Persons with histories that will affect bone mineral status were excluded from the study. The resulting study population consisted of 137 persons. The data was used to examine, using statistical methods, the parameters which determine bone mineral status of normal persons. The DEXA and In-vivo Neutron Activation Analysis (IVNAA) data on the same persons were compared. Further, the data was used to determine the age at which peak BMD is attained in this normal population. The Measurements were made using a DEXA instrument made by Hologic Inc., Model 1000 W.

This study examined the English Language Learning Strategies between local and international Chinese students who share the same cultural background but have been exposed to different learning experiences. Given the significant number of local and international Chinese students enrolled in educational institutions, there is a need to understand the differences and similarities in the learning strategies of these two groups. The sample for the study comprised of 60 local and 50 international Chinese students currently enrolled at a local private college. The Oxford Strategy Inventory for Language Learning (SILL was administered as a measure of learning strategy preferences. The study reveals that language learning experiences as well as socioeconomic status impact the learning strategy adopted by both local and international Chinese students. The findings of this study point to the need to address the needs of these students in order to enhance their English language learning experience in Malaysia.

    In-Vivo Neutron Activation Analysis (IVNAA) and Dual Energy X-ray Absorptiometry (DEXA) are routinely used in our laboratory for clinical and research investigation of Bone Mineral Content (BMC) and Bone Mineral Density (BMD in g/sq.cm). These two techniques differ in many respects. IVNAA is an established technique where 49 Ca radioisotope induced by the 48 Ca(n,gamma) 49 Ca reaction is measured to determine BMC. In DEXA, two X-rays of different energies are used and based on the known attenuation characteristics of bone and soft tissue and the measured attenuated signals, the BMC is calculated. Very little radiation dose (<0.1 mSv) is given in DEXA compared to IVNAA (3 to 5 mSv). Site specific information can be obtained in the former. Although DEXA is easier to use both the techniques are in use in the investigation of Osteopenia. The BMD, a clinical useful parameter, is a function of age and not height. The body calcium content determined by IVNAA is a function of height and not age. These differences are not yet clearly understood. Work is underway to determine the influence of several factors e.g. age, weight on BMD. We are also conducting experiments to determine the peak BMC and BMD of Canadians. The role of various life styles e.g. exercise, diet, ethnicity are being investigated as a determinant of BMD and BMC. Also the effects and safety of many drugs in the treatment of osteopenia and osteoporosis are also being studied. (author)

    2018-01-01

    Ongoing modal analyses and model correlation are performed on different configurations of the International Space Station (ISS). These analyses utilize on-orbit dynamic measurements collected using four main ISS instrumentation systems: External Wireless Instrumentation System (EWIS), Internal Wireless Instrumentation System (IWIS), Space Acceleration Measurement System (SAMS), and Structural Dynamic Measurement System (SDMS). Remote Sensor Units (RSUs) are network relay stations that acquire flight data from sensors. Measured data is stored in the Remote Sensor Unit (RSU) until it receives a command to download data via RF to the Network Control Unit (NCU). Since each RSU has its own clock, it is necessary to synchronize measurements before analysis. Imprecise synchronization impacts analysis results. A study was performed to evaluate three different synchronization techniques: (i) measurements visually aligned to analytical time-response data using model comparison, (ii) Frequency Domain Decomposition (FDD), and (iii) lag from cross-correlation to align measurements. This paper presents the results of this study.

    Mycobacterium spp. are renowned for being the causative agent of diseases like leprosy, Buruli ulcer and tuberculosis in human beings. With more and more mycobacterial genomes being sequenced, any knowledge generated from comparative genomic analysis would provide better insights into the biology, evolution, phylogeny and pathogenicity of this genus, thus helping in better management of diseases caused by Mycobacterium spp.With this motivation, we constructed MycoCAP, a new comparative analysis platform dedicated to the important genus Mycobacterium. This platform currently provides information of 2108 genome sequences of at least 55 Mycobacterium spp. A number of intuitive web-based tools have been integrated in MycoCAP particularly for comparative analysis including the PGC tool for comparison between two genomes, PathoProT for comparing the virulence genes among the Mycobacterium strains and the SuperClassification tool for the phylogenic classification of the Mycobacterium strains and a specialized classification system for strains of Mycobacterium abscessus. We hope the broad range of functions and easy-to-use tools provided in MycoCAP makes it an invaluable analysis platform to speed up the research discovery on mycobacteria for researchers.

    International Nuclear Information System (INIS)

    Leon, R.L.

    1992-01-01

    The paper presents the concept of comparative trace analysis and shows it to be very effective in diagnosing motor operated valve (MOV) problems. Comparative trace analysis is simply the process of interpreting simultaneously gathered traces, each presenting a different perspective on the same series of events. The opening and closing of a motor operated valve is such a series of events. The simultaneous traces are obtained using Liberty Technologies' Valve Operation Test and Evaluation System (VOTES)reg-sign. The traces include stem thrust, motor current, motor power factor, motor power, switch actuations, vibration in three different frequency bands, spring pack displacement, and spring pack force. Spare and auxiliary channels enable additional key parameters to be measured, such as differential pressure and stem displacement. Though not specifically illustrated in this paper, the VOTES system also provides for FFT analysis on all traces except switches

    Results are presented from an analysis of economic benefits (or losses), in the form of the life cycle cost savings, resulting from the development of the National Launch System (NLS) family of launch vehicles. The analysis was carried out by comparing various NLS-based architectures with the current Shuttle/Titan IV fleet. The basic methodology behind this NLS analysis was to develop a set of annual payload requirements for the Space Station Freedom and LEO, to design launch vehicle architectures around these requirements, and to perform life-cycle cost analyses on all of the architectures. A SEI requirement was included. Launch failure costs were estimated and combined with the relative reliability assumptions to measure the effects of losses. Based on the analysis, a Shuttle/NLS architecture evolving into a pressurized-logistics-carrier/NLS architecture appears to offer the best long-term cost benefit.

  4. Embedded Hyperchaotic Generators: A Comparative Analysis

    Science.gov (United States)

    Sadoudi, Said; Tanougast, Camel; Azzaz, Mohamad Salah; Dandache, Abbas

    In this paper, we present a comparative analysis of FPGA implementation performances, in terms of throughput and resources cost, of five well known autonomous continuous hyperchaotic systems. The goal of this analysis is to identify the embedded hyperchaotic generator which leads to designs with small logic area cost, satisfactory throughput rates, low power consumption and low latency required for embedded applications such as secure digital communications between embedded systems. To implement the four-dimensional (4D) chaotic systems, we use a new structural hardware architecture based on direct VHDL description of the forth order Runge-Kutta method (RK-4). The comparative analysis shows that the hyperchaotic Lorenz generator provides attractive performances compared to that of others. In fact, its hardware implementation requires only 2067 CLB-slices, 36 multipliers and no block RAMs, and achieves a throughput rate of 101.6 Mbps, at the output of the FPGA circuit, at a clock frequency of 25.315 MHz with a low latency time of 316 ns. Consequently, these good implementation performances offer to the embedded hyperchaotic Lorenz generator the advantage of being the best candidate for embedded communications applications.

    For environmental monitoring of radioactive materials, the competent authorities of the States and Federal Government of Germany continuously perform measurements and make their results accessible to the public in an appropriate way. In order to guarantee the comparability of measured values and a high degree of reliability of the applied methods, the authorities in charge of carrying out such tasks are obliged to take part in the comparative analyses (ring tests) organized by the central offices of the Federal Government. Therefore, the aim of this comparative analysis performed by order of the Federal Ministry of the Environment, Nature Protection and Reactor Safety consists mainly in providing the measuring offices in charge of monitoring waters, with samples with known tritium contents in order to get an overview of the accuracy of currently used processes; check the accuracy of the determinations performed, and, if necessary, detect and eliminate systematic errors; check, in particular by means of the samples T2 and T3, the calibration of the measuring devices and, if necessary, make corrections. To this effect, the comparative analysis fulfills the function of quality control of the processes used in environmental monitoring. (orig./BBR) [de

    Full Text Available On 1st January 2015 the Eurasian Economic Union (EAEU - a new integration block comprising initially Belarus, Kazakhstan, and Russia, and later that year also Armenia and Kyrgyzstan - appeared on the world map. This paper endeavors to identify the EAEU countries’ long-term international comparative advantages within four basic groups of goods according to the OECD classification of manufacturing industries based on technology intensity. The analysis, using B. Balassa’s RCA methodology and covering the years 2000-2014, indicates that these countries lack competitiveness, with none of them possessing any RCAs in the high-technology category whereas in the medium-hightechnology category - only Belarus. In contrast, all the EAEU countries fared the best in the medium-low-technology category, which is mostly attributable to the resources-based character of their economies. Surprisingly, dramatically low international competitiveness was recorded by Kazakhstan and Russia.

    The Enterobacter cloacae species includes an extremely diverse group of bacteria that are associated with plants, soil and humans. Publication of the complete genome sequence of the plant growth-promoting endophytic E. cloacae subsp. cloacae ENHKU01 provided an opportunity to perform the first comparative genome analysis between strains of this dynamic species. Examination of the pan-genome of E. cloacae showed that the conserved core genome retains the general physiological and survival genes of the species, while genomic factors in plasmids and variable regions determine the virulence of the human pathogenic E. cloacae strain; additionally, the diversity of fimbriae contributes to variation in colonization and host determination of different E. cloacae strains. Comparative genome analysis further illustrated that E. cloacae strains possess multiple mechanisms for antagonistic action against other microorganisms, which involve the production of siderophores and various antimicrobial compounds, such as bacteriocins, chitinases and antibiotic resistance proteins. The presence of Type VI secretion systems is expected to provide further fitness advantages for E. cloacae in microbial competition, thus allowing it to survive in different environments. Competition assays were performed to support our observations in genomic analysis, where E. cloacae subsp. cloacae ENHKU01 demonstrated antagonistic activities against a wide range of plant pathogenic fungal and bacterial species.

    Full Text Available The well known events which had taken place in our country over the period 1989-2001 provoked adverse effects on foreign trade exchange of the total economy, agriculture and commodities of plant origin. These effects and changes were analyzed using corresponding indices for the sub periods 1989-1992 and 1998-2001. The foreign trade exchange balance was substantially negative in both sub periods over the analyzed period showing an aggravating trend. Export covering import declined from 78.09% to only 47.71%. The positive balance of exchange of agricultural, especially commodities of plant origin in the first four years was turned into a negative balance of exchange in the second four years. Export covering import at the agricultural level declined from 164.79% to 78.58% and at the level of commodities of plant origin from 201,76% to 87.35%. There was a significant disturbance of commodity and regional structure exchange. The share of agriculture in the total export of the country was raised from 13.82% to 18.16%. The share of plant originating commodities in the total export of agriculture was raised from 71,96% to 86,34%. Basic agricultural products predominated in the export. In addition, in the domestic export the share of developed countries decreased which contributed to poor export results and increased the import dependence of the country. Considering the above said, the need arises to increase substantially agricultural production, i.e. commodities of plant origin. The structure and output of these productions should meet the needs of both domestic and foreign markets. International standards need to be applied in order to take hold of new foreign markets, exporting high technology processed products, using intensive and efficient promotive activities. Subsequently, greater investments and a planned production are needed, liberalization and especially the system of import control in foreign trade exchange of agricultural products, i

    In this study, 5 different gas hydrate production scenarios were modeled by the CMG STARS, HydateResSim, MH-21 HYDRES, STOMP-HYD and the TOUGH+HYDRATE reservoir simulators for comparative purposes. The 5 problems ranged in complexity from 1 to 3 dimensional with radial symmetry, and in horizontal dimensions of 20 meters to 1 kilometer. The scenarios included (1) a base case with non-isothermal multi-fluid transition to equilibrium, (2) a base case with gas hydrate (closed-domain hydrate dissociation), (3) dissociation in a 1-D open domain, (4) gas hydrate dissociation in a one-dimensional radial domain, similarity solutions, (5) gas hydrate dissociation in a two-dimensional radial domain. The purpose of the study was to compare the world's leading gas hydrate reservoir simulators in an effort to improve the simulation capability of experimental and naturally occurring gas hydrate accumulations. The problem description and simulation results were presented for each scenario. The results of the first scenario indicated very close agreement among the simulators, suggesting that all address the basics of mass and heat transfer, as well as overall process of gas hydrate dissociation. The third scenario produced the initial divergence among the simulators. Other differences were noted in both scenario 4 and 5, resulting in significant corrections to algorithms within several of the simulators. The authors noted that it is unlikely that these improvements would have been identified without this comparative study due to a lack of real world data for validation purposes. It was concluded that the solution for gas hydrate production involves a combination of highly coupled fluid, heat and mass transport equations combined with the potential for formation or disappearance of multiple solid phases in the system. The physical and chemical properties of the rocks containing the gas hydrate depend on the amount of gas hydrate present in the system. Each modeling and

    1995-09-01

    The Department of Energy`s (DOE) Strategic Plan (April 1994) states that DOE`s long-term vision includes world leadership in environmental restoration and waste management activities. The activities of the DOE Office of Environmental Management (EM) can play a key role in DOE`s goals of maintaining U.S. global competitiveness and ensuring the continuation of a world class science and technology community. DOE`s interest in attaining these goals stems partly from its participation in organizations like the Trade Policy Coordinating Committee (TPCC), with its National Environmental Export Promotion Strategy, which seeks to strengthen U.S. competitiveness and the building of public-private partnerships as part of U.S. industrial policy. The International Interactions Field Office task will build a communication network which will facilitate the efficient and effective communication between DOE Headquarters, Field Offices, and contractors. Under this network, Headquarters will provide the Field Offices with information on the Administration`s policies and activities (such as the DOE Strategic Plan), interagency activities, as well as relevant information from other field offices. Lawrence Livermore National Laboratory (LLNL) will, in turn, provide Headquarters with information on various international activities which, when appropriate, will be included in reports to groups like the TPCC and the EM Focus Areas. This task provides for the collection, review, and analysis of information on the more significant international environmental restoration and waste management initiatives and activities which have been used or are being considered at LLNL. Information gathering will focus on efforts and accomplishments in meeting the challenges of providing timely and cost effective cleanup of its environmentally damaged sites and facilities, especially through international technical exchanges and/or the implementation of foreign-development technologies.

Then, specific features of each alternative are highlighted, by contrasting the advantages and disadvantages of both types of FDI. Based on this analysis, some conclusions are drawn in the end concerning the most important factors that influence the decision of a company whether to choose a greenfield investment or an acquisition.

  19. Comparative international studies of osteoporosis using isotope techniques

    In Europe, there are great geographic variations in rates of osteoporotic fracture. The MEDOS study, a case-control study of hip fracture in southern Europe, demonstrated rates that in some age groups varied geographically by more than an order of magnitude. Additionally the prevalences of vertebral deforinities vary over a 3-fold range in both sexes. The incidence of hip fracture has also been shown to vary between another populations with apparently lower rates in Hong Kong and South Africa in Europe and North America. The greatest projected increases in hip fracture incidence will occur in China and South East Asia. It seems likely that the spread of fracture risk can at least be accounted for partly by differences in bone density. Bone density in later life is dependent on the maximum bone mass ('peak' bone mass) attained in early adulthood and the subsequent rate of loss. The purpose of this study was to determine whether early adult BMD varied between populations and to explore environmental and nutritional contributions to any detennined differences. The data analysed to-date demonstrate a highly significant difference in young adult bone mass across the centers. These differences are only partly attributable to differences in height and weight. By and large, low femoral neck BMD is accompanied by low spinal BMD. Femoral neck BMD appears constant between the age of 25-45 years, but this will require confirmation by further statistical analysis. The impact of family history, environmental factors and nutrition will be explored in subsequent analyses

  20. Comparative economic analysis: Anaerobic digester case study

    International Nuclear Information System (INIS)

    Lusk, P.D.

    1991-01-01

    An economic guide is developed to assess the value of anaerobic digesters used on dairy farms. Two varieties of anaerobic digesters, a conventional mixed-tank mesophilic and an innovative earthen psychrophilic, are comparatively evaluated using a cost-effectiveness index. The two case study examples are also evaluated using three other investment merit statistics: simple payback period, net present value, and internal rate of return. Life-cycle savings are estimated for both varieties, with sensitivities considered for investment risk. The conclusion is that an earthen psychrophilic digester can have a significant economic advantage over a mixed-tank mesophilic digester because of lower capital cost and reduced operation and maintenance expenses. Because of this economic advantage, additional projects are being conducted in North Carolina to increase the rate of biogas utilization. The initial step includes using biogas for milk cooling at the dairy farm where the existing psychrophilic digester is located. Further, a new project is being initiated for electricity production with thermal reclaim at a swine operation

    Fungi of the phylum Basidiomycota (basidiomycetes), make up some 37percent of the described fungi, and are important in forestry, agriculture, medicine, and bioenergy. This diverse phylum includes symbionts, pathogens, and saprotrophs including the majority of wood decaying and ectomycorrhizal species. To better understand the genetic diversity of this phylum we compared the genomes of 35 basidiomycetes including 6 newly sequenced genomes. These genomes span extremes of genome size, gene number, and repeat content. Analysis of core genes reveals that some 48percent of basidiomycete proteins are unique to the phylum with nearly half of those (22percent) found in only one organism. Correlations between lifestyle and certain gene families are evident. Phylogenetic patterns of plant biomass-degrading genes in Agaricomycotina suggest a continuum rather than a dichotomy between the white rot and brown rot modes of wood decay. Based on phylogenetically-informed PCA analysis of wood decay genes, we predict that that Botryobasidium botryosum and Jaapia argillacea have properties similar to white rot species, although neither has typical ligninolytic class II fungal peroxidases (PODs). This prediction is supported by growth assays in which both fungi exhibit wood decay with white rot-like characteristics. Based on this, we suggest that the white/brown rot dichotomy may be inadequate to describe the full range of wood decaying fungi. Analysis of the rate of discovery of proteins with no or few homologs suggests the value of continued sequencing of basidiomycete fungi.

    Effectiveness and safety of warfarin is associated with the time in therapeutic range (TTR) with an international normalised ratio (INR) of 2·0-3·0. In the Randomised Evaluation of Long-term Anticoagulation Therapy (RE-LY) trial, dabigatran versus warfarin reduced both stroke and haemorrhage. We aimed to investigate the primary and secondary outcomes of the RE-LY trial in relation to each centre's mean TTR (cTTR) in the warfarin population. In the RE-LY trial, 18 113 patients at 951 sites were randomly assigned to 110 mg or 150 mg dabigatran twice daily versus warfarin dose adjusted to INR 2·0-3·0. Median follow-up was 2·0 years. For 18 024 patients at 906 sites, the cTTR was estimated by averaging TTR for individual warfarin-treated patients calculated by the Rosendaal method. We compared the outcomes of RE-LY across the three treatment groups within four groups defined by the quartiles of cTTR. RE-LY is registered with ClinicalTrials.gov, number NCT00262600. The quartiles of cTTR for patients in the warfarin group were: less than 57·1%, 57·1-65·5%, 65·5-72·6%, and greater than 72·6%. There were no significant interactions between cTTR and prevention of stroke and systemic embolism with either 110 mg dabigatran (interaction p=0·89) or 150 mg dabigatran (interaction p=0·20) versus warfarin. Neither were any significant interactions recorded with cTTR with regards to intracranial bleeding with 110 mg dabigatran (interaction p=0·71) or 150 mg dabigatran (interaction p=0·89) versus warfarin. There was a significant interaction between cTTR and major bleeding when comparing 150 mg dabigatran with warfarin (interaction p=0·03), with less bleeding events at lower cTTR but similar events at higher cTTR, whereas rates of major bleeding were lower with 110 mg dabigatran than with warfarin irrespective of cTTR. There were significant interactions between cTTR and effects of both 110 mg and 150 mg dabigatran versus warfarin on the composite of all

    This article examines the intersecting roles of gender, ethnicity, and professional status in shaping the experiences of internationally educated health professionals in Canada. The article is based on 140 semi-structured qualitative interviews with internationally trained nurses and physicians who came to Canada within past 10 years with the intention to practice their profession. Describing the challenging process of professional integration in Canada, our participants highlighted incidents of discrimination they experienced along the way. Although some of the participants from both professional groups experienced racial discrimination, the context of those experiences differed. Physicians rarely reported instances of discrimination in communication with patients or nurses. Instead, they were concerned with instances of discrimination within their own professional group. Nurses, on the other hand, reported discrimination at the hands of patients and their families as well as racialization by physicians, management, and other nurses. We conclude our article with a reflection on the role that gender and professional status play in shaping the experiences of ethnic discrimination of internationally educated health professionals. © The Author(s) 2015.

    Undertaking an overview of privacy conditions can be a valuable step in comparing privacy and security requirements in different national regulations. The qualitative content analysis was found a suitable approach for this purpose because it enables the detection of fine characteristics. By using an incremental design, it is possible to adapt the coding system to include additional partners. However, the current coding system has the limitation that heterogeneity between the agreements leads to a fine granularity of categories that hamper the comparability between partners. Despite these problems, the approach allows the comparison of data privacy and supports the development of a data integration process for international harmonisation.

    Propolis is a resinous mixture of substances collected and processed from various botanical sources by honeybees (Apis mellifera). We recently obtained Hawaiian propolis, the study of which, to our knowledge, has not been reported. The purpose of this study was to analyze the composition of Hawaiian propolis and to identify its botanical origin. A comparative analysis of Hawaiian and Okinawan propolis and of the glandular trichomes on Macaranga tanarius fruit (the botanical origin of Okinawan propolis) was performed using reversed-phase high-performance liquid chromatography coupled with high resolution-electrospray mass spectrometry. Hawaiian propolis contained nine prenylflavonoids that were also isolated from Okinawan propolis. In conclusion, we suggest that the botanical origin of Hawaiian propolis is M. tanarius, the same as that of Okinawan propolis.

    Fungi of the phylum Basidiomycota (basidiomycetes), make up some 37percent of the described fungi, and are important in forestry, agriculture, medicine, and bioenergy. This diverse phylum includes the mushrooms, wood rots, symbionts, and plant and animal pathogens. To better understand the diversity of phenotypes in basidiomycetes, we performed a comparative analysis of 35 basidiomycete fungi spanning the diversity of the phylum. Phylogenetic patterns of lignocellulose degrading genes suggest a continuum rather than a sharp dichotomy between the white rot and brown rot modes of wood decay. Patterns of secondary metabolic enzymes give additional insight into the broad array of phenotypes found in the basidiomycetes. We suggest that the profile of an organism in lignocellulose-targeting genes can be used to predict its nutritional mode, and predict Dacryopinax sp. as a brown rot; Botryobasidium botryosum and Jaapia argillacea as white rots.

This fact suggests that the election of candidates for these positions is a part of strategic transformation of the body. There is a reason to believe that the strategy of the international organizations, not only related to their desire to be effectively involved in actions within their mandate, but also with the desire to increase their influence in comparison with the

    Ebolavirus is the pathogen for Ebola Hemorrhagic Fever (EHF). This disease exhibits a high fatality rate and has recently reached a historically epidemic proportion in West Africa. Out of the 5 known Ebolavirus species, only Reston ebolavirus has lost human pathogenicity, while retaining the ability to cause EHF in long-tailed macaque. Significant efforts have been spent to determine the three-dimensional (3D) structures of Ebolavirus proteins, to study their interaction with host proteins, and to identify the functional motifs in these viral proteins. Here, in light of these experimental results, we apply computational analysis to predict the 3D structures and functional sites for Ebolavirus protein domains with unknown structure, including a zinc-finger domain of VP30, the RNA-dependent RNA polymerase catalytic domain and a methyltransferase domain of protein L. In addition, we compare sequences of proteins that interact with Ebolavirus proteins from RESTV-resistant primates with those from RESTV-susceptible monkeys. The host proteins that interact with GP and VP35 show an elevated level of sequence divergence between the RESTV-resistant and RESTV-susceptible species, suggesting that they may be responsible for host specificity. Meanwhile, we detect variable positions in protein sequences that are likely associated with the loss of human pathogenicity in RESTV, map them onto the 3D structures and compare their positions to known functional sites. VP35 and VP30 are significantly enriched in these potential pathogenicity determinants and the clustering of such positions on the surfaces of VP35 and GP suggests possible uncharacterized interaction sites with host proteins that contribute to the virulence of Ebolavirus.

    Full Text Available The key processes in the business of insurance companies which define the financial viability of their business activities, as the most important element, are the adequate amount of technical reserves. A qualitative assessment of the technical reserves level is the basic support to the management of the key business processes and proper strategic and financial decision-making in order to maximize the viability, profitability, competitiveness, and further development of the company. Based on the data on the operations of an insurance company, within a single line of insurance, different, in practice, most frequently used methods were applied in order to determine the deviation amplitude of the projected amounts from the actual claims. Another direction of research focuses on actuarial practice in non-life insurance companies operating in the territory of the Republic of Serbia. The comparative analysis of the obtained projection points to the fact that the chosen methods, commonly used in actuarial practice in the Republic of Serbia, should be monitored and reviewed. The results of the multidirectional research and detection of the existing problems provide a useful framework and a stimulating mechanism, as well as the guidelines to improve the operations and better positioning of insurance in the commercial and economic environment of the Republic of Serbia.

    Full Text Available BACKGROUND: The threat of avian influenza and the 2004-2005 influenza vaccine supply shortage in the United States have sparked a debate about optimal vaccination strategies to reduce the burden of morbidity and mortality caused by the influenza virus. METHODS AND FINDINGS: We present a comparative analysis of two classes of suggested vaccination strategies: mortality-based strategies that target high-risk populations and morbidity-based strategies that target high-prevalence populations. Applying the methods of contact network epidemiology to a model of disease transmission in a large urban population, we assume that vaccine supplies are limited and then evaluate the efficacy of these strategies across a wide range of viral transmission rates and for two different age-specific mortality distributions. We find that the optimal strategy depends critically on the viral transmission level (reproductive rate of the virus: morbidity-based strategies outperform mortality-based strategies for moderately transmissible strains, while the reverse is true for highly transmissible strains. These results hold for a range of mortality rates reported for prior influenza epidemics and pandemics. Furthermore, we show that vaccination delays and multiple introductions of disease into the community have a more detrimental impact on morbidity-based strategies than mortality-based strategies. CONCLUSIONS: If public health officials have reasonable estimates of the viral transmission rate and the frequency of new introductions into the community prior to an outbreak, then these methods can guide the design of optimal vaccination priorities. When such information is unreliable or not available, as is often the case, this study recommends mortality-based vaccination priorities.

  6. International comparative studies in mathematics education: are we obsessed with the international rankings of measured educational outcomes?

    Science.gov (United States)

    Tsai, Tsung-Lung; Li, Hui-Chuan

    2017-11-01

    Over the past few decades, researchers, policy makers, educators and the general public, who have an interest in mathematics education in different countries, pay a great deal of attention to the results from international comparative studies. Of great interest to the international studies is the results of Eastern students consistently achieving higher marks among the participating countries. In recent years, we have seen a climate of intense global economic competition and a growing belief in the key role of education, which have persuaded governments to become increasingly obsessed with the international rankings of measured educational outcomes. Accordingly, educational policy is increasingly driven by national attempts to "copy" the perceived advantage associated with the educational strategies and techniques of other countries. In this note, we present a discussion of the benefits and criticisms of one of these international comparative studies: Trends in International Mathematics and Science Study (TIMSS) studies. In so doing, we attempt to call attention to a continuously growing culture of "teaching to the test" in mathematics education.

    This paper presents the performance analysis of a planar solid-oxide fuel cell (SOFC) under direct internal reforming conditions. A detailed solid-oxide fuel cell model is used to study the influences of various operating parameters on cell performance. Significant differences in efficiency and power density are observed for isothermal and adiabatic operational regimes. The influence of air number, specific catalyst area, anode thickness, steam to carbon (s/c) ratio of the inlet fuel, and extend of pre-reforming on cell performance is analyzed. In all cases except for the case of pre-reformed fuel, adiabatic operation results in lower performance compared to isothermal operation. It is further discussed that, though direct internal reforming may lead to cost reduction and increased efficiency by effective utilization of waste heat, the efficiency of the fuel cell itself is higher for pre-reformed fuel compared to non-reformed fuel. Furthermore, criteria for the choice of optimal operating conditions for cell stacks operating under direct internal reforming conditions are discussed. (author)

    Full Text Available In this article the negotiations and peace processes in the Third World are analized from a comparative viewpoint in order to focus in on the case of Centroamerica. Reference is made to the special features and common elements of those peace processes in otherregions of the Third World and they are compared to those which have taken place in Centroamerica. It is a retrospective and comparative analysis. For this reason, the author has decided to carry out a brief typology of those conflicts offered by Centroamerica: inNicaragua, El Salvador and Guatemala. Later, the author goes on to analyse the most relevant peace and negotiation processes involving the Third World including one or two from Latin America: the cases of Panama, Afghanistan, Iran-Iraq, Colombia, southern Africa (South Africa, Namibia and Angola and Cambodia. Later, the author goes overthe peace process periods in Centroamerica and the temporary contradictions which are presented by internal conflict, regional conflict and geopolitical conflict. Finally, a comparative methodological exercise is carried out which allows to focus on modes of implementation of the peace processes.

    Cox, Emily; Martin, Bradley C; Van Staa, Tjeerd; Garbe, Edeltraut; Siebert, Uwe; Johnson, Michael L

    2009-01-01

    The goal of comparative effectiveness analysis is to examine the relationship between two variables, treatment, or exposure and effectiveness or outcome. Unlike data obtained through randomized controlled trials, researchers face greater challenges with causal inference with observational studies. Recognizing these challenges, a task force was formed to develop a guidance document on methodological approaches to addresses these biases. The task force was commissioned and a Chair was selected by the International Society for Pharmacoeconomics and Outcomes Research Board of Directors in October 2007. This report, the second of three reported in this issue of the Journal, discusses the inherent biases when using secondary data sources for comparative effectiveness analysis and provides methodological recommendations to help mitigate these biases. The task force report provides recommendations and tools for researchers to mitigate threats to validity from bias and confounding in measurement of exposure and outcome. Recommendations on design of study included: the need for data analysis plan with causal diagrams; detailed attention to classification bias in definition of exposure and clinical outcome; careful and appropriate use of restriction; extreme care to identify and control for confounding factors, including time-dependent confounding. Design of nonrandomized studies of comparative effectiveness face several daunting issues, including measurement of exposure and outcome challenged by misclassification and confounding. Use of causal diagrams and restriction are two techniques that can improve the theoretical basis for analyzing treatment effects in study populations of more homogeneity, with reduced loss of generalizability.

    The application of instrumental neutron activation analysis for the determination of long-lived rare earth elements (REE) in rock samples is considered in this work. Two different methods are statistically compared: the well established external standard method carried out using standard reference materials, and the internal standard method (ISM), using Fe, determined through X-ray fluorescence analysis, as an element-comparator. The ISM proved to be the more precise method for a wide range of REE contents and can be recommended for routine practice. (author)

  7. Inside-out: comparing internally generated and externally generated basic emotions.

    Science.gov (United States)

    Salas, Christian E; Radovic, Darinka; Turnbull, Oliver H

    2012-06-01

    A considerable number of mood induction (MI) procedures have been developed to elicit emotion in normal and clinical populations. Although external procedures (e.g., film clips, pictures) are widely used, a number of experiments elicit emotion by using self-generated procedures (e.g., recalling an emotional personal episode). However, no study has directly compared the effectiveness of two types of internal versus external MI across multiple discrete emotions. In the present experiment, 40 undergraduate students watched film clips (external procedure) and recalled personal events (internal procedure) inducing 4 basic emotions (fear, anger, joy, sadness) and later completed a self-report questionnaire. Remarkably, both internal and external procedures elicited target emotions selectively, compared with nontarget emotions. When contrasting the intensity of target emotions, both techniques showed no significant differences, with the exception of Joy, which was more intensely elicited by the internal procedure. Importantly, when considering the overall level of intensity, it was always greater in the internal procedure, for each stimulus. A more detailed investigation of the data suggest that recalling personal events (a type of internal procedure) generates more negative and mixed blends of emotions, which might account for the overall higher intensity of the internal mood induction.

A statistical comparison between rigid fixation and monocortical fixation has been difficult because of multiple terms, definitions, and technical variations. The purpose of this study was to use the meta-analysis tool to combine information from multiple studies and to compare complication rates for different fixation methods. An English language literature search was conducted for articles on mandibular angle fractures. Information was collected on four variables of interest: compression/noncompression technique, monocortical/bicortical screws, number of plates, and location of plates. Five outcome rates were analyzed: infection, reoperation, hardware removal, malunion, and nonunion. Meta-analyses were run using Comprehensive Meta Analysis, version 2.2.03. Twenty-four studies with relevant data on the variables and outcomes of interest met the inclusion criteria. Significantly higher rates of infection, reoperation, and hardware removal were found for compression compared with noncompression, two plates compared with one plate, and for plates located on both the inferior and superior borders as compared with superior or inferior only. There were also significantly higher infection rates for bicortical screws compared with monocortical screws and higher malunion rates for compression compared with noncompression plating techniques. The results of this meta-analysis found lower complication rates with the use of noncompression, monocortical, and single-plate fixation, supporting the trend toward a single, superiorly placed, monocortical miniplate for fixation of mandibular angle fractures.

    Flowering is an important agronomic trait that determines crop yield. Soybean is a major oilseed legume crop used for human and animal feed. Legumes have unique vegetative and floral complexities. Our understanding of the molecular basis of flower initiation and development in legumes is limited. Here, we address this by using a computational approach to examine flowering regulatory genes in the soybean genome in comparison to the most studied model plant, Arabidopsis. For this comparison, a genome-wide analysis of orthologue groups was performed, followed by an in silico gene expression analysis of the identified soybean flowering genes. Phylogenetic analyses of the gene families highlighted the evolutionary relationships among these candidates. Our study identified key flowering genes in soybean and indicates that the vernalisation and the ambient-temperature pathways seem to be the most variant in soybean. A comparison of the orthologue groups containing flowering genes indicated that, on average, each Arabidopsis flowering gene has 2-3 orthologous copies in soybean. Our analysis highlighted that the CDF3, VRN1, SVP, AP3 and PIF3 genes are paralogue-rich genes in soybean. Furthermore, the genome mapping of the soybean flowering genes showed that these genes are scattered randomly across the genome. A paralogue comparison indicated that the soybean genes comprising the largest orthologue group are clustered in a 1.4 Mb region on chromosome 16 of soybean. Furthermore, a comparison with the undomesticated soybean (Glycine soja) revealed that there are hundreds of SNPs that are associated with putative soybean flowering genes and that there are structural variants that may affect the genes of the light-signalling and ambient-temperature pathways in soybean. Our study provides a framework for the soybean flowering pathway and insights into the relationship and evolution of flowering genes between a short-day soybean and the long-day plant, Arabidopsis.

    The bony labyrinth of vertebrates houses the semicircular canals. These sense rotational accelerations of the head and play an essential role in gaze stabilisation during locomotion. The sizes and shapes of the semicircular canals have hypothesised relationships to agility and locomotory modes in many groups, including birds, and a burgeoning palaeontological literature seeks to make ecological interpretations from the morphology of the labyrinth in extinct species. Rigorous tests of form-function relationships for the vestibular system are required to support these interpretations. We test the hypothesis that the lengths, streamlines and angles between the semicircular canals are related to body size, wing kinematics and flying style in birds. To do this, we applied geometric morphometrics and multivariate phylogenetic comparative methods to a dataset of 64 three-dimensional reconstructions of the endosseous labyrinth obtained using micro-computed tomography scanning of bird crania. A strong relationship between centroid size of the semicircular canals and body size indicates that larger birds have longer semicircular canals compared with their evolutionary relatives. Wing kinematics related to manoeuvrability (and quantified using the brachial index) explain a small additional portion of the variance in labyrinth size. We also find strong evidence for allometric shape change in the semicircular canals of birds, indicating that major aspects of the shape of the avian labyrinth are determined by spatial constraints. The avian braincase accommodates a large brain, a large eye and large semicircular canals compared with other tetrapods. Negative allometry of these structures means that the restriction of space within the braincase is intense in small birds. This may explain our observation that the angles between planes of the semicircular canals of birds deviate more strongly from orthogonality than those of mammals, and especially from agile, gliding and flying

  15. A comparative analysis of capacity adequacy policies

    2007-06-01

    In this paper a stochastic dynamic optimization model is used to analyze the effect of different generation adequacy policies in restructured power systems. The expansion decisions of profit-maximizing investors are simulated under a number of different market designs: Energy Only with and without a price cap, Capacity Payment, Capacity Obligation, Capacity Subscription, and Demand Elasticity. The results show that the overall social welfare is reduced compared to a centralized social welfare optimization for all policies except Capacity Subscription and Demand Elasticity. In particular, an energy only market with a low price cap leads to a significant increase in involuntary load shedding. Capacity payments and obligations give additional investment incentives and more generating capacity, but also result in a considerable transfer of wealth from consumers to producers due to the capacity payments. Increased demand elasticity increases social welfare, but also results in a transfer from producers to consumers, compared to the theoretical social welfare optimum. In contrast, the capacity subscription policy increases the social welfare, and both producers and consumers benefit. This is possible because capacity subscription explicitly utilizes differences in consumers' preferences for uninterrupted supply. This advantage must be weighed against the cost of implementation, which is not included in the model.

    To analyze and understand historical changes in economic, environmental, employment or other socio-economic indicators, it is useful to assess the driving forces or determinants that underlie these changes. Two techniques for decomposing indicator changes at the sector level are structural decomposition analysis (SDA) and index decomposition analysis (IDA). For example, SDA and IDA have been used to analyze changes in indicators such as energy use, CO 2 -emissions, labor demand and value added. The changes in these variables are decomposed into determinants such as technological, demand, and structural effects. SDA uses information from input-output tables while IDA uses aggregate data at the sector-level. The two methods have developed quite independently, which has resulted in each method being characterized by specific, unique techniques and approaches. This paper has three aims. First, the similarities and differences between the two approaches are summarized. Second, the possibility of transferring specific techniques and indices is explored. Finally, a numerical example is used to illustrate differences between the two approaches

    Full Text Available Higher education system occupies a special place in the policy of each nation. Regardless of geographical location, socio-economic or cultural differences, the need to improve the education offered for population by facilitating access to higher education becomes more and more important. Providing a suitable framework for the personal development of each student is expensive and involves high amounts of money. From the analyses carried out we couldn\\'t identify the substantial differences between the way it is structured and organized education system worldwide. However, we were able to identify a number of common elements that create a global University System. The need to invest in human resources through structural reforms in each country is present, and therefore a higher indention to pay greater attention to the development of the higher education system. In our work we decided to analyze education systems in countries like United States of America (USA, United Kingdom (GB, China (CHN, Germany (DE, France (FR, Russian Federation (RU, Japan (JPN average values recorded for EU-27 and last but not least Romania (RO. Although the investment in the University system is hard to quantify, it is unanimously acknowledged that a country can achieve a competitive advantage in international relations through a very well prepared and trained personnel. The countries reviewed in this paper have different policies when it comes to financial support of the University System. If Germany and France have decided to get involved directly in supporting the system by allocating the necessary funds from the State budget, another European country, the United Kingdom, decided to apply a policy diametrically opposite, similar to that existing in the USA and cover in a lesser degree the needs of universities in Government funds. Regardless of the policy adopted the results are intended to be the same: facilitating access to university education, a high quality of

    Random Early Detection (RED) is an active queue management (AQM) mechanism for routers on the Internet. In this paper, performance of RED and Adaptive RED are compared from the viewpoint of nonlinear dynamics. In particular, we reveal the relationship between the performance of the network and its nonlinear dynamical behavior. We measure the maximal Lyapunov exponent and Hurst parameter of the average queue length of RED and Adaptive RED, as well as the throughput and packet loss rate of the aggregate traffic on the bottleneck link. Our simulation scenarios include FTP flows and Web flows, one-way and two-way traffic. In most situations, Adaptive RED has smaller maximal Lyapunov exponents, lower Hurst parameters, higher throughput and lower packet loss rate than that of RED. This confirms that Adaptive RED has better performance than RED

    Full Text Available We compared the information retrieval performances of some popular search engines (namely, Google, Yahoo, AlltheWeb, Gigablast, Zworks and AltaVista and Bing/MSN in response to a list of ten queries, varying in complexity. These queries were run on each search engine and the precision and response time of the retrieved results were recorded. The first ten documents on each retrieval output were evaluated as being ‘relevant’ or ‘non-relevant’ for evaluation of the search engine’s precision. To evaluate response time, normalised recall ratios were calculated at various cut-off points for each query and search engine. This study shows that Google appears to be the best search engine in terms of both average precision (70% and average response time (2 s.

    We compare the behavior of solutions of Goodwin's business cycle equation in the form of neutral delay differential equation with fixed delay (NDDE model) and in the form of the differential equations of 3rd, 4th and 5th orders (ODE model's). Such ODE model's (Taylor series expansion of NDDE in powers of θ) are proposed in N. Dharmaraj and K. Vela Velupillai [6] for investigation of the short periodic sawthooth oscillations in NDDE. We show that the ODE's of 3rd, 4th and 5th order may approximate the asymptotic behavior of only main Goodwin's mode, but not the sawthooth modes. If the order of the Taylor series expansion exceeds 5, then the approximate ODE becomes unstable independently of time lag θ.

    Full Text Available Information is limited on how firearms move from legal possession to illegal possession and use in criminal activities, largely because of data collection capacity and a lack of recent, exhaustive recovery data across jurisdictions. This article includes both an analysis of firearms trace data and prisoner interviews across multiple jurisdictions: New Orleans, Louisiana, Prince George’s County, Maryland, and Chicago, Illinois. Findings indicate that recoveries and trace successes vary across jurisdictions and by type of crime. Jurisdiction regulations were associated with the proportion of guns purchased in state and time to recovery but not with purchaser characteristics. Interviews from imprisoned offenders in two jurisdictions revealed the most common method of obtaining a crime gun was to steal it or buy it off the street.

    The CMTB Thwacker hardware operates as a testbed analogue for the Flight Thwacker and Sieve components of CHIMRA, a device on the Curiosity Rover. The sieve separates particles with a diameter smaller than 150 microns for delivery to onboard science instruments. The sieving behavior of the testbed hardware should be similar to the Flight hardware for the results to be meaningful. The elastodynamic behavior of both sieves was studied analytically using the Rayleigh Ritz method in conjunction with classical plate theory. Finite element models were used to determine the mode shapes of both designs, and comparisons between the natural frequencies and mode shapes were made. The analysis predicts that the performance of the CMTB Thwacker will closely resemble the performance of the Flight Thwacker within the expected steady state operating regime. Excitations of the testbed hardware that will mimic the flight hardware were recommended, as were those that will improve the efficiency of the sieving process.

    Mechanical ventilation is a therapeutic action for newborns with respiratory diseases but may have side effects. Correct equipment knowledge and training may limit human errors. We aimed to test different neonatal mechanical ventilators' performances by an acquisition module (a commercial pressure sensor plus an isolated chamber and a dedicated software). The differences (ΔP) between peak pressure values and end-expiration pressure were investigated for each ventilator. We focused on discrepancies among measured and imposed pressure data. A statistical analysis was performed. We investigated the measured/imposed ΔP relation. The ΔP do not reveal univocal trends related to ventilation setting parameters and the data distributions were non-Gaussian. Measured ΔP represent a significant parameter in newborns' ventilation, due to the typical small volumes. The investigated ventilators showed different tendencies. Therefore, a deep specific knowledge of the intensive care devices is mandatory for caregivers to correctly exploit their operating principles.

  5. Comparative analysis of cystatin superfamily in platyhelminths.

    Directory of Open Access Journals (Sweden)

    Aijiang Guo

    Full Text Available The cystatin superfamily is comprised of cysteine proteinase inhibitors and encompasses at least 3 subfamilies: stefins, cystatins and kininogens. In this study, the platyhelminth cystatin superfamily was identified and grouped into stefin and cystatin subfamilies. The conserved domain of stefins (G, QxVxG was observed in all members of platyhelminth stefins. The three characteristics of cystatins, the cystatin-like domain (G, QxVxG, PW, a signal peptide, and one or two conserved disulfide bonds, were observed in platyhelminths, with the exception of cestodes, which lacked the conserved disulfide bond. However, it is noteworthy that cestode cystatins had two tandem repeated domains, although the second tandem repeated domain did not contain a cystatin-like domain, which has not been previously reported. Tertiary structure analysis of Taenia solium cystatin, one of the cestode cystatins, demonstrated that the N-terminus of T. solium cystatin formed a five turn α-helix, a five stranded β-pleated sheet and a hydrophobic edge, similar to the structure of chicken cystatin. Although no conserved disulfide bond was found in T. solium cystatin, the models of T. solium cystatin and chicken cystatin corresponded at the site of the first disulfide bridge of the chicken cystatin. However, the two models were not similar regarding the location of the second disulfide bridge of chicken cystatin. These results showed that T. solium cystatin and chicken cystatin had similarities and differences, suggesting that the biochemistry of T. solium cystatin could be similar to chicken cystatin in its inhibitory function and that it may have further functional roles. The same results were obtained for other cestode cystatins. Phylogenetic analysis showed that cestode cystatins constituted an independent clade and implied that cestode cystatins should be considered to have formed a new clade during evolution.

    Full Text Available In June 2013, Mount Fuji was nominated as a UNESCO World Heritage site. Subsequently, a new system was piloted encouraging climbers to make a donation of 1000 JPY to help improve environmental conservation. This research is part of a larger study from 2008 to 2014 monitoring the characteristics and behaviour of Fuji climbers. Specifically, this paper investigates Japanese and international climbers to compare their level of awareness and willingness to pay the new donation. Results revealed broad differences between Japanese and international climbers, with 71% of the latter unaware about the new fee prior to climbing, compared to only 16% of Japanese. 77% of Japanese supported the new fee compared to only 50% of international climbers. These findings seem to suggest that prior awareness is vital for compliance, as cross-analysis showed that among international climbers, 72% of those who knew in advance were willing to pay, compared to 43% of those without prior awareness. The new trial climbing fee will be extended for the entire 2014 season on a 24 hour basis, so these findings have implications for improved management based on a better understanding of market segments and more effective messaging to raise awareness, particularly among foreign climbers.

    Across the globe, public acceptance of nuclear power is a crucial factor for governmental establishment of a nuclear energy program. Therefore, it is important to understand the determinants of public acceptance of nuclear power. This study examines the effects of knowledge, trust, risk, and benefit related factors on public acceptance of nuclear power across 19 countries. We consider three levels of public acceptance – strongly accept, reluctantly accept, and oppose – and classify countries into four groups according to the ratio of those three levels of public acceptance. Our results indicate that knowledge of nuclear inspection is more effective than trust in inspection authorities in creating stronger public acceptance among people in the countries with a high level of reluctant acceptance and a low level of strong acceptance, while trust in inspection authorities is more important than knowledge of nuclear inspection for the selection between opposition and reluctant acceptance in countries with a low level of reluctant acceptance and a high level of strong acceptance. Without grouping the countries, we found that trust in inspection authorities is crucial for the decision between opposition and reluctant acceptance. Additionally, the generation of electricity has the most positive effect on public acceptance of nuclear power. - Highlights: • We examine public acceptance (PA) of nuclear power across 19 countries. • Three levels of PA – strongly accept, reluctantly accept, and oppose – are considered. • Knowledge is most effective in creating stronger PA. • Trust is effective in shifting PA from opposition to reluctant acceptance. • Low risk and benefit of electricity generation enhance PA the most

    2016-04-01

    Smoking and drinking constitute two risk factors contributing to the rising burden of non-communicable diseases in low- and middle-income countries. Both issues have gained increased international attention, but tobacco control has made more sustained progress in terms of international and domestic policy commitments, resources dedicated to reducing harm, and reduction of tobacco use in many high-income countries. The research presented here offers insights into why risk factors with comparable levels of harm experience different trajectories of global attention. The analysis focuses particular attention on the role of dedicated global health networks composed of individuals and organizations producing research and engaging in advocacy on a given health problem. Variation in issue characteristics and the policy environment shape the opportunities and challenges of global health networks focused on reducing the burden of disease. What sets the tobacco case apart was the ability of tobacco control advocates to create and maintain a consensus on policy solutions, expand their reach in low- and middle-income countries and combine evidence-based research with advocacy reaching beyond the public health-centered focus of the core network. In contrast, a similar network in the alcohol case struggled with expanding its reach and has yet to overcome divisions based on competing problem definitions and solutions to alcohol harm. The tobacco control network evolved from a group of dedicated individuals to a global coalition of membership-based organizations, whereas the alcohol control network remains at the stage of a collection of dedicated and like-minded individuals.

    Posterior-stabilized total knee prostheses were introduced to address instability secondary to loss of posterior cruciate ligament function, and they have either fixed or mobile bearings. Mobile bearings were developed to improve the function and longevity of total knee prostheses. In this study, the International Consortium of Orthopaedic Registries used a distributed health data network to study a large cohort of posterior-stabilized prostheses to determine if the outcome of a posterior-stabilized total knee prosthesis differs depending on whether it has a fixed or mobile-bearing design. Aggregated registry data were collected with a distributed health data network that was developed by the International Consortium of Orthopaedic Registries to reduce barriers to participation (e.g., security, proprietary, legal, and privacy issues) that have the potential to occur with the alternate centralized data warehouse approach. A distributed health data network is a decentralized model that allows secure storage and analysis of data from different registries. Each registry provided data on mobile and fixed-bearing posterior-stabilized prostheses implanted between 2001 and 2010. Only prostheses associated with primary total knee arthroplasties performed for the treatment of osteoarthritis were included. Prostheses with all types of fixation were included except for those with the rarely used reverse hybrid (cementless tibial and cemented femoral components) fixation. The use of patellar resurfacing was reported. The outcome of interest was time to first revision (for any reason). Multivariate meta-analysis was performed with linear mixed models with survival probability as the unit of analysis. This study includes 137,616 posterior-stabilized knee prostheses; 62% were in female patients, and 17.6% had a mobile bearing. The results of the fixed-effects model indicate that in the first year the mobile-bearing posterior-stabilized prostheses had a significantly higher hazard

    Each code has its own solver for depletion, which can produce different depletion calculation results. In order to produce reference solutions for depletion calculation comparison, sensitivity studies should be preceded for each depletion solver. The sensitivity tests for burnup interval, number of depletion zones, and recoverable energy per fission (Q-value) were performed in this paper. For the comparison of depletion calculation results, usually the multiplication factors are compared as a function of burnup. In this study, new comparison methods have been introduced by using the number density of isotope or element, and a cumulative flux instead of burnup. In this paper, optimum depletion calculation options are determined through the sensitivity study of the burnup intervals and the number of depletion intrazones. Because the depletion using CRAM solver performs well for large burnup intervals, smaller number of burnup steps can be used to produce converged solutions. It was noted that the depletion intra-zone sensitivity is only pin-type dependent. The 1 and 10 depletion intra-zones for the normal UO2 pin and gadolinia rod, respectively, are required to obtain the reference solutions. When the optimized depletion calculation options are used, the differences of Q-values are found to be a main cause of the differences of solutions. In this paper, new comparison methods were introduced for consistent code-to-code comparisons even when different kappa libraries were used in the depletion calculations

    All human activities are related with the energy consumption. Energy requirements will continue to rise, due to the modern life and the developing countries growth. Most of the energy demand emanates from fossil fuels. Fossil fuels combustion has negative environmental impacts, with the CO 2 production to be dominating. The fulfillment of the Kyoto protocol criteria requires the minimization of CO 2 emissions. Thus the management of the CO 2 emissions is an urgent matter. The use of appliances with low energy use and the adoption of an energy policy that prevents the unnecessary energy use, can play lead to the reduction of carbon emissions. A different route is the introduction of ''clean'' energy sources, such as renewable energy sources. Last but not least, the development of carbon sequestration methods can be promising technique with big future potential. The objective of this work is the analysis and comparison of different carbon sequestration and deposit methods. Ocean deposit, land ecosystems deposit, geological formations deposit and radical biological and chemical approaches will be analyzed

    take relevance as communication strategies to improve the promotion of a tourist destination. Among the functions performed by the municipal decentralized autonomous governments (GAD are regulate, control and promote the development of cantonal tourism. Most municipalities have their website where they display tourism information, but very few have an exclusive website to publish tourism information. In addition, as shown in this paper, the tourist information provided is very low. The method that was used in this research was the content analysis through a systematic, objective and quantitative analysis. The study was carried out through a direct observation of the municipal websites in Ecuador and their counterparts in Colombia and Spain. The results showed that the vast majority of municipal GADs own websites but very few are the websites that are making appropriate use of the services that an exclusive web destined to the tourism could offer.  Ecuador should work harder to improve its tourism promotion on the Web if it really wants to become a tourist power as posed by the Ecuadorian government.

    The end of the Cold War era has presented practitioners and analysts of international non-proliferation, arms control and disarmament (NACD) the opportunity to focus more intently on the range and scope of NACD treaties and their verification. Aside from obvious favorable and well-publicized developments in the field of nuclear non-proliferation, progress also has been made in a wide variety of arenas, ranging from chemical and biological weapons, fissile material, conventional forces, ballistic missiles, to anti-personnel landmines. Indeed, breaking from the constraints imposed by the Cold War United States-Soviet adversarial zero-sum relationship that impeded the progress of arms control, particularly on a multilateral level, the post Cold War period has witnessed significant developments in NACD commitments, initiatives, and implementation. The goals of this project - in its final iteration - will be fourfold. First, it will lead to the creation of a costing analysis model adjustable for uses in several current and future arms control verification tasks. Second, the project will identify data accumulated in the cost categories outlined in Table 1 in each of the five cases. By comparing costs to overall effectiveness, the application of the model will demonstrate desirability in each of the cases (see Chart 1). Third, the project will identify and scrutinize 'political costs' as well as real expenditures and investment in the verification regimes (see Chart 2). And, finally, the project will offer some analysis on the relationship between national and multilateral forms of arms control verification, as well as the applicability of multilateralism as an effective tool in the verification of international non-proliferation, arms control, and disarmament agreements.

    Full Text Available With the emergence of globalization, it has become increasingly important for all citizens to possess an international perspective. The trend of internationalizing educational systems has also emerged in various countries. Thus, to explore the degree to which students can possess international perspectives is an important topic worthy of studying. The purpose of this study was to develop a questionnaire to investigate the current status of the international perspectives of and the differences between sixth graders in Taipei and Shanghai. A total of 1,300 sixth -graders were randomly stratified from the two cities, with 1,111 valid questionnaires returned for further analysis. A significant difference was found in sixth graders’ international perspectives between the two cities. Differences of their demographic characteristics were also identified. More similarities than differences in their backgrounds and experiences were identified. Both similarities and differences were also found in their parents’ level of education and occupation.

    Allograft use has increased recently with the rising use of allograft materials in breast surgery. There are few data that compare the performance of the various allograft materials in this application, despite marketing efforts by the manufacturers to present one allograft material as superior to another. Phalloplasty is a procedure that uses allografts for penis girth augmentation. Preparation of these grafts differs with each manufacturer. We report our experience with 3 different types of allografts for this procedure. This allows for the comparison of these materials in their performance with a single model. Forty-seven patients who underwent penis girth enhancement with allograft material were reviewed. All patients underwent circumferential grafting to the shaft of the penis at the level of Buck's fascia. Graft materials included AlloDerm (n = 9), Belladerm (n = 20), and Repriza (n = 21). Charts were reviewed for material type, presence and type of infection, wound exposure, and graft loss with attention to the type of allograft material that was used. Follow-up ranged from 1 to 120 months with an average of 11.25 months. Infection, defined as an open wound with graft exposure, occurred in 20 (42%) of 47 patients. Of these, graft exposure only occurred in 17 (36%) patients, whereas 3 (6%) patients sustained total graft loss. Graft exposure or loss occurred in 3 patients who had AlloDerm, 9 patients with Belladerm, and 8 patients with Repriza. No patients with AlloDerm sustained graft loss, whereas 2 patients with Belladerm and 1 patient with Repriza sustained graft loss. There were no statistical differences among these graft types with regard to infection or graft loss. Three different brands of allograft material were used in 1 surgical procedure and followed up for their performance with regard to exposure and infection. In this model, there is no difference in the rate of infection in these materials despite their different methods of preparation

    Against the backdrop of demographic change and economic reconfiguration, recruiting international students, especially those at tertiary level, has drawn growing attention from advanced economies as part of a broad strategy to manage highly skilled migration. This comparative study focuses on three English speaking countries receiving international students: Canada, the United States, and the United Kingdom. International student policies, in particular entry and immigration regulations, and the trends in student mobility since the late 1990s are examined drawing on secondary data. By exploring the issue from the political economy perspectives, this study identifies distinct national strategies for managing student mobility, determines key factors shaping the environment of student migration in each nation, and addresses the deficiency of human capital theory in the analysis of global competition for high skills.

    Devulcanization of ground tire rubber (GTR) was done using twin screw extruder (TSE) and internal mixer (IM). Processing parameters were varied to analyze its effect on gel content. Fourier Transform Infrared Spectroscopy (FTIR) analysis was performed as qualitative technique to confirm structural change. The devulcanized rubbers with the least gel content percentage produced in both TSE and IM were then used as filler in natural rubber (NR)/coconut coir (CC) composite preparation. Effects of gel content percentage on NR/CC composite tensile strength and elongation at break were analyzed. The results show that the gel content decreased by 41% for sample processed in TSE and 50% in IM compared to control sample. Overall, the devulcanization is influenced by high energy generated by thermal or thermo-mechanical process. FTIR spectra show chemically structural changes of GTR as C=C, CH2, CH3 with higher intensity for IM sample than its counterpart indicated devulcanization. The replacement of GTR to DGTR on NR/CC/GTR composites provided less network structures and resulted better tensile strength and elongation at break.

    2016-04-01

    Full Text Available Post Second World War liberal economic order and its institutions have been challenged with the rapidly growing powerful economies of some Asian and Latin American countries in the last decade. Yet, there is ambiguity in international political economy field with regard to conceptualizing and categorizing these emerging economies. This study mainly aims to ravel out this obstacle by offering a new quantitative benchmarking framework. In other words, this study proposes a new evaluation criteria set for assessing emerging economies with combining testable domestic and systematic factors. Accordingly, this study presents the cross-country comparison by using quantitative benchmarking analysis between IBSA -India, Brazil and South Africa- and MIST -Mexico, Indonesia, South Korea and Turkey- countries over the period 2008- 2012. We compare these countries based on the criteria of economic growth, human development index, foreign direct investment, and official development assistance. This study also aims to evaluate the group performance of these newly emerging economies- namely the rise of IBSA and MIST countries-in a comparative perspective. In conclusion, the performance of these countries -from both group-of-country and individual-country perspectives- are discussed in light of the results

  17. Prospects for international trade in environmental services: An analysis of international carbon emission off-sets

    International Nuclear Information System (INIS)

    Swisher, J.N.

    1991-01-01

    This dissertation presents a case study analysis in which the costs to a US electric utility of reducing its carbon dioxide (CO 2 ) emissions are compared with the costs of carbon-saving forestry projects in Costa Rica and Guatemala. The results show that a large electric utility in the south-central US would find it relatively inexpensive, even profitable given a conducive regulatory treatment, to reduce its CO 2 emissions by a few percent over the next ten years, through direct investment in energy end-use efficiency improvements. In comparison, the costs of the forestry projects studied in Central America range from $1/TC to a worst-case value of about $55/TC, with most project costs between $5 and $13/TC, depending on the type of project, the climate, and the opportunity cost of land. The total amount of CO 2 storage potential is significant, about 100 million tons per country, but not enough to suggest that forestry can offset more than a few percent of global CO 2 emissions from fossil fuel use. These case studies suggest that international trade in the environmental service of reducing global CO 2 accumulation could have significant economic and ecological benefits. A transaction in which a utility pays for forestry projects in exchange for credit against an emission reduction policy is an example of an international carbon emission offset (ICEO). ICEO's could provide a currency for funding carbon-saving services as a way to comply with national policies to reduce CO 2 emissions, as long as compliance is allowed through investments in other countries. This type of North-South transfer is necessary to reconcile economic efficiency and international equity, because of the disparity between the national allocations of responsibility for greenhouse gas emissions and opportunities for emission reductions

  18. Comparison report of RPV pressurised thermal shock - international comparative assessment study (PTS ICAS)

    1999-01-01

    A summary of the recently completed International Comparative Assessment Study of Pressurized- Thermal-Shock in Reactor Pressure Vessels (RPV PTS ICAS) is presented here to record the results in actual and comparative fashions. The ICAS Project brought together an international group of experts from research, utility and regulatory organizations to perform a comparative evaluation of analysis methodologies employed in the assessment of RPV integrity under PTS loading conditions. The Project was sponsored jointly by Gesellschaft fuer Anlagen- und Reaktorsicherheit (GRS), Koeln, Germany, and Oak Ridge National Laboratory (ORNL), USA, with assistance from the Organization for Economic Co-operation and Development (OECD)/Nuclear Energy Agency (NEA)/Committee on the Safety of Nuclear Installations (CSNI)/Principal Working Group (PWG) No. 3 (Integrity of Components and Structures). The ICAS Project grew out of a strong interest expressed by participants in the previous FALSIRE II Project to proceed with further evaluations of analysis methods used in RPV integrity assessment. A Launch Meeting for the ICAS Project was held at GRS-Koeln, during June 1996, where an emphasis was placed on identifying the different approaches to RPV integrity assessment being employed within the international nuclear technology community. Also a Problem Statement was drafted that defined a Western type four-loop RPV with cladding on the inner surface. Also, a detailed task matrix was defined that included a set of transient thermal-mechanical loading conditions postulated to result from loss-of-coolant accidents. The primary focus of the analyses was on the behaviour of relatively shallow cracks under these conditions. The assessment activities based on the Problem Statement were divided under three tasks: deterministic fracture mechanics (DFM), probabilistic fracture mechanics (PFM) and thermal-hydraulic mixing (THM). An Intermediate Workshop was held at OECD/NEA-Paris during June 1997, to

    To estimate the relative number of deaths in member countries of the Organisation for Economic Co-operation and Development (OECD) from international terrorism and road crashes. Data on deaths from international terrorism (US State Department database) were collated (1994-2003) and compared to the road injury deaths (year 2000 and 2001 data) from the OECD International Road Transport Accident Database. In the 29 OECD countries for which comparable data were available, the annual average death rate from road injury was approximately 390 times that from international terrorism. The ratio of annual road to international terrorism deaths (averaged over 10 years) was lowest for the United States at 142 times. In 2001, road crash deaths in the US were equal to those from a September 11 attack every 26 days. There is a large difference in the magnitude of these two causes of deaths from injury. Policy makers need to be aware of this when allocating resources to preventing these two avoidable causes of mortality.

    Venous thromboembolism (VTE) is a major cause of morbidity and mortality with significant heterogeneity in its management, both within our local practice and in international guidelines. To provide a holistic evaluation of 'real-world' Australian experience in the warfarin era, including how we compare to international guidelines. Retrospective evaluation of VTE from July 2011 to December 2012 at two major hospitals in Melbourne, Australia. These results were compared to recommendations in the international guidelines. A total of 752 episodes involving 742 patients was identified. Contrary to international guidelines, an unwarranted heritable thrombophilia screen was performed in 22.0% of patients, amounting to a cost of AU$29 000. The duration of anticoagulation was longer compared to international recommendations, although the overall recurrence (3.2/100 person-years) and clinically significant bleeding rates (2.4/100 person-years) were comparable to 'real-world' data. Unprovoked VTE (hazard ratio 2.06; P = 0.01) was a risk factor for recurrence, and there was no difference in recurrence between major VTE (proximal deep vein thrombosis (DVT) and/or pulmonary embolism) and isolated distal DVT (3.02 vs 3.94/100 person-years; P = 0.25). Fourteen patients were subsequently diagnosed with malignancy, and patients with recurrent VTE had increased risk of prospective cancer diagnosis (relative risk 6.68; P management strategies, including excessive thrombophilia screening and longer duration of anticoagulation.

    With economic and cultural globalization, the trend of globalization of higher education becomes inevitable. Using the concept of competitiveness, the authors established a principal component analysis (PCA) model to examine disciplinary competitiveness in stomatology of various higher education institutions worldwide. A total of forty-four universities entered the final list according to these calculations. Possible reasons for their selection were explored and explained at macro and micro levels. The authors further accessed various sources of data and summarized several suggestions for enhancing disciplinary competitiveness for other universities in pursuit of promoting their position in the global spectrum.

  3. Policy lessons from comparing mortality from two global forces: international terrorism and tobacco

    Directory of Open Access Journals (Sweden)

    Wilson Nick

    2005-12-01

    Full Text Available Abstract Background The aim of this study was to compare the mortality burdens from two global impacts on mortality: international terrorism and the major cause of preventable death in developed countries – tobacco use. We also sought to examine the similarities and differences between these two causes of mortality so as to better inform the policy responses directed at prevention. Methods Data on deaths from international terrorism were obtained from a US State Department database for 1994–2003. Estimates for tobacco-attributable deaths were based on Peto et al 2003. The countries were 37 developed and East European countries. Results and discussion The collective annualized mortality burden from tobacco was approximately 5700 times that of international terrorism. The ratio of annual tobacco to international terrorism deaths was lowest for the United States at 1700 times, followed by Russia at 12,900 times. The tobacco death burden in all these countries was equivalent to the impact of an 11 September type terrorist attack every 14 hours. Different perceptions of risk may contribute to the relative lack of a policy response to tobacco mortality, despite its relatively greater scale. The lack is also despite tobacco control having a stronger evidence base for the prevention measures used. Conclusion This comparison highlights the way risk perception may determine different policy responses to global forces causing mortality. Nevertheless, the large mortality differential between international terrorism and tobacco use has policy implications for informing the rational use of resources to prevent premature death.

  4. Support for international trade law: The US and the EU compared.

    Eckhardt, Jappe; Elsig, Manfred

    2015-10-01

    In this article we compare US and EU support for bilateral and multilateral international trade law. We assess the support for international law of both trading blocs by focusing on the following four dimensions: leadership, consent, compliance and internalization. Although we find strong support for international trade law from both the US and the EU in general, we also witness some variation, most notably in relation to the design of preferential trade agreements (PTAs) and compliance with World Trade Organization (WTO) law. Turning to explaining these (moderate) differences, we argue that outcomes in US trade policy can best be explained by a domestic political factor, namely the direct influence of interest groups. Although the involvement of societal interests also goes a long way in explaining EU behavior, it does not tell the entire story. We posit that, in EU trade policy, institutions are a particular conditioning factor that needs to be stressed. Moreover, we suggest that foreign policy considerations in managing trade relations have characterized EU's support for international trade law.

    Full Text Available This comparative case study addresses a timely issue engaging researchers involved in the internationalisation of Nordic Higher Education, in the context of Sweden and Finland. The study examines a hypothetical imaginary in the transition between university international policy statements and their understandings from the position of a globalised episteme. The investigation forms a tag-project as part of a funded large international research project examining ethical internationalism in times of global crises, involving a partnership between more than twenty higher education institutions in excess of ten countries across five continents. The data was collected using a mixed-methods design, whilst being controlled across the matched data collection period in 2013-2014. Data consisted of policy texts, surveys and interviews. The current research inquiry reports on a within and across comparative analyses of certain policy texts and follow-up interviews with university management. The results yield logical support for a global higher education imaginary driving internationalisation in ways which reveal paradoxical associations between the imagined and the real worlds of international scholar-practitioners.

    2017-12-01

    Full Text Available Contract formation by electronic means nowadays is a widespread phenomenon. Nevertheless electronic contracting has been thoroughly explored by scholars all over the world and regulated both internationally and domestically, there still remain some issues which need to be carefully analyzed. In our view, the most essential question raised by electronic contracting is whether there is a need to amend substantial contract law provisions with regard to peculiarities of contracts concluded by electronic means. Seeking the answer to this question several approaches have been formulated, but none of them seems to be completely appropriate. In this paper the answer is also attempted to be found. For this purpose a comparative analysis of doctrine, legislation and judicial practice of certain states is performed. Particularly, offer, acceptance and moment of electronic contract formation are explored. On the basis of this research the following conclusion is done: amendments to substantial contract law provisions are not always necessary to improve the regulation of electronic contracting. Nevertheless the provisions of law should be applied correctly to the disputes arising from electronic contract formation taking into account the peculiarities of such contracts.

    Vladimir Gennadievich Ivanov

    2015-12-01

    Full Text Available In the given article, the author analyzes the concept of state capacity, widely popular among political scientists and international relations specialists. The author proves that the evaluations of the level of state capacity of the developing and postcommunist countries based on popular comparative ratings are generally biased because of methodological defects and discrepancy of the whole theory as well as politicization and indoctrination of the given ratings. The negative evaluations of the quality of the government and state capacity of a country could be used to discredit and delegitimize the political regime as well as substantiation of mass protests and color revolutions and a tool of information war. The author concludes that numerous comparative international ratings are often used as a tool of political influence.

  10. Public versus internal conceptions of addiction: An analysis of internal Philip Morris documents.

    Directory of Open Access Journals (Sweden)

    2018-05-01

    Full Text Available Tobacco addiction is a complex, multicomponent phenomenon stemming from nicotine's pharmacology and the user's biology, psychology, sociology, and environment. After decades of public denial, the tobacco industry now agrees with public health authorities that nicotine is addictive. In 2000, Philip Morris became the first major tobacco company to admit nicotine's addictiveness. Evolving definitions of addiction have historically affected subsequent policymaking. This article examines how Philip Morris internally conceptualized addiction immediately before and after this announcement.We analyzed previously secret, internal Philip Morris documents made available as a result of litigation against the tobacco industry. We compared these documents to public company statements and found that Philip Morris's move from public denial to public affirmation of nicotine's addictiveness coincided with pressure on the industry from poor public approval ratings, the Master Settlement Agreement (MSA, the United States government's filing of the Racketeer Influenced and Corrupt Organizations (RICO suit, and the Institute of Medicine's (IoM's endorsement of potentially reduced risk products. Philip Morris continued to research the causes of addiction through the 2000s in order to create successful potentially reduced exposure products (PREPs. While Philip Morris's public statements reinforce the idea that nicotine's pharmacology principally drives smoking addiction, company scientists framed addiction as the result of interconnected biological, social, psychological, and environmental determinants, with nicotine as but one component. Due to the fragmentary nature of the industry document database, we may have missed relevant information that could have affected our analysis.Philip Morris's research suggests that tobacco industry activity influences addiction treatment outcomes. Beyond nicotine's pharmacology, the industry's continued aggressive advertising

    Full Text Available In the world of investing and trading, in order to have a definite advantage and constantly create profit, you need to have a strategic approach. Generally speaking, the two main schools of thought and strategies in financial markets are fundamental and technical analysis. Fundamental and technical analysis differ in several aspects, such as the way of functioning and execution, the time horizon used, the tools used and their objective. These differences lead to certain advantages and disadvantages of each of the analyses. Fundamental and technical analysis are also a subject of critical reviews by the academic and scientific community and many of these reviews concern the methods of their application, i.e. the possibility of combining the two analyses and using them complementarily to fully utilize their strengths and advantages.

    In this paper a methodology was followed in order to support the decision-making of one industrial unit regarding its internal logistics system. The addressed factory was facing issues with their internal logistics approach. Some alternatives were pointed out and a proper total cost of ownership (TCO) analysis was developed. This analysis was taken in order to demonstrate the more cost-effective solution for the internal logistics system. This tool is more and more valued by the companies, due to their willing to reduce the costs that are associated with the way of doing business. Despite the proposal of the best choice for the internal logistics system of the enterprise, this study also intends to present some conclusions about the match between the nature of the industrial unit and the logistics systems that best fit the requirements of those.

    2015-12-01

    Full Text Available In order to avoid battery failure, a battery management system (BMS is necessary. Battery state of charge (SOC and state of health (SOH are part of information provided by a BMS. This research analyzes methods to estimate SOH based lithium polymer battery on change of its internal resistance and its capacity. Recursive least square (RLS algorithm was used to estimate internal ohmic resistance while coloumb counting was used to predict the change in the battery capacity. For the estimation algorithm, the battery terminal voltage and current are set as the input variables. Some tests including static capacity test, pulse test, pulse variation test and before charge-discharge test have been conducted to obtain the required data. After comparing the two methods, the obtained results show that SOH estimation based on coloumb counting provides better accuracy than SOH estimation based on internal ohmic resistance. However, the SOH estimation based on internal ohmic resistance is faster and more reliable for real application

    Full Text Available This article is devoted to the problem of the value orientations of modern young people, who begin their independent life in the current conditions of the difficult changes in the political, social and economic life of the countries. Greece and Russia are two of the countries, which are in crisis due to the globalisation processes. The article gives the details of the results of the empirical study of the value orientations in Greek and Russian students and presents their comparative analysis. It identifies the similarity of the value orientations in Greek and Russian students, which appears in the fact that the value of health (it seems quite difficult to achieve and the value of self-development and self-improvement (an easily achievable value are important to the students of both groups; and the values of creativity and financially-secure life (the value, which is difficult to achieve have little significance. The significant differences between the groups lie in the fact, that the Russian group is dominated by the people with the focus on business, the value of interesting work is important to them, they are more focused on business activity, as well as on love, and the interpersonal relations are less significant for them. The Greek students are often focused on themselves, on their families; freedom in actions, confidence and friendship are more important to them. The peculiarities of the value orientations of the Russian students are internally more conflicting: first of all, we are talking of an important value of love and its dissatisfaction, the important value of an interesting job and the idea that it is difficult to achieve these values. The internal conflict of the Greek students often concerns the importance and the low availability of the value of freedom. The study shows that the peculiarities of the value orientations of Russian students reflect the socio-economic changes in the society, while the values of Greek students

The analysis of mathematical content showed that the three textbooks have different approaches and priorities in terms of the positions of chapters and weights of the quadratics units, and the time allocated to them within the respective curricular programs. It was also found that the Turkish textbook covers a greater number of learning outcomes targeted for quadratics among the three mathematics syllabi, showing a detailed treatment of the topic compared to the other two textbooks.Key Words: Content analysis, international comparative studies, mathematics textbooks

  1. Frameworks for comparing emissions associated with production, consumption, and international trade.

    2012-01-03

    While the problem of climate change is being perceived as increasingly urgent, decision-makers struggle to agree on the distribution of responsibility across countries. In particular, representatives from countries hosting emissions-intensive exporting industries have argued that the importers of emissions-intensive goods should bear the responsibility, and ensuing penalties. Indeed, international trade and carbon leakage appear to play an increasingly important role in the carbon emissions debate. However, definitions of quantities describing the embodiment of carbon emissions in internationally traded products, and their measurement, have to be sufficiently robust before being able to underpin global policy. In this paper we critically examine a number of emissions accounting concepts, examine whether the ensuing carbon balances are compatible with monetary trade balances, discuss their different interpretations, and highlight implications for policy. In particular, we compare the emissions embodied in bilateral trade (EEBT) method which considers total trade flows with domestic emission intensities, with the multi-regional input-output (MRIO) method which considers trade only into final consumption with global emission intensities. If consumption-based emissions of different countries were to be compared, we would suggest an MRIO approach because of the global emissions coverage inherent in this method. If trade-adjusted emission inventories were to be compared, we would suggest an EEBT approach due to the consistency with a monetary trade balance.

    A suitable definition of primary care to capture the variety of prevailing international organisation and service-delivery models is lacking. Evaluation of strength of primary care in Europe. International comparative cross-sectional study performed in 2009-2010, involving 27 EU member states, plus Iceland, Norway, Switzerland, and Turkey. Outcome measures covered three dimensions of primary care structure: primary care governance, economic conditions of primary care, and primary care workforce development; and four dimensions of primary care service-delivery process: accessibility, comprehensiveness, continuity, and coordination of primary care. The primary care dimensions were operationalised by a total of 77 indicators for which data were collected in 31 countries. Data sources included national and international literature, governmental publications, statistical databases, and experts' consultations. Countries with relatively strong primary care are Belgium, Denmark, Estonia, Finland, Lithuania, the Netherlands, Portugal, Slovenia, Spain, and the UK. Countries either have many primary care policies and regulations in place, combined with good financial coverage and resources, and adequate primary care workforce conditions, or have consistently only few of these primary care structures in place. There is no correlation between the access, continuity, coordination, and comprehensiveness of primary care of countries. Variation is shown in the strength of primary care across Europe, indicating a discrepancy in the responsibility given to primary care in national and international policy initiatives and the needed investments in primary care to solve, for example, future shortages of workforce. Countries are consistent in their primary care focus on all important structure dimensions. Countries need to improve their primary care information infrastructure to facilitate primary care performance management.

    BACKGROUND Sepsis is a common cause of morbidity and mortality among hospitalized patients. The prevalence of this condition has increased significantly in different parts of the world. Patients admitted to dermatology wards often have severe loss of skin barrier and use systemic corticosteroids, which favor the development of sepsis. OBJECTIVES To evaluate the prevalence of sepsis among patients admitted to a dermatology ward compared to that among patients admitted to an internal medicine ward. METHODS It is a cross-sectional, observational, comparative study that was conducted at Hospital Santa Casa de Belo Horizonte. Data were collected from all patients admitted to four hospital beds at the dermatology and internal medicine wards between July 2008 and July 2009. Medical records were analyzed for the occurrence of sepsis, dermatologic diagnoses, comorbidities, types of pathogens and most commonly used antibiotics. RESULTS We analyzed 185 medical records. The prevalence of sepsis was 7.6% among patients admitted to the dermatology ward and 2.2% (p = 0.10) among those admitted to the internal medicine ward. Patients with comorbidities, diabetes mellitus and cancer did not show a higher incidence of sepsis. The main agent found was Staphylococcus aureus, and the most commonly used antibiotics were ciprofloxacin and oxacillin. There was a significant association between sepsis and the use of systemic corticosteroids (p <0.001). CONCLUSION It becomes clear that epidemiological studies on sepsis should be performed more extensively and accurately in Brazil so that efforts to prevent and treat this serious disease can be made more effectively.

    This in vitro study compared the tooth color and the ultrastructure of internal dental tissues before and after internal bleaching. Sodium perborate was placed in the pulp chamber of endodontically treated molars and sealed with intermediate restorative material. The test samples were stored in a physiologic solution, and the bleaching agent was replaced every 7 days. A control group was used. After 1 month, the colors of the test and control samples were measured with a colorimeter, and the internal surfaces were observed under field emission scanning electron microscopy (FESEM). Statistically significant differences were found between the test and control sample colors. The FESEM ultrastructure analysis of the internal enamel and dentin surfaces did not show any changes after the internal bleaching. The results of the present study show that sodium perborate is effective in bleaching nonvital teeth and does not produce ultrastructural changes in the dental tissues.

    Pajewski, Lara; Marciniak, Marian; Benedetto, Andrea; Tosti, Fabio

    2016-04-01

    Ground Penetrating Radar (GPR) can be effectively used for non-destructive testing of composite structures and diagnostics affecting the whole life-cycle of civil engineering works. Nevertheless, few recognised international standards exist in this field and inhomogeneous recommendations are present in different countries. Moreover, the levels of knowledge, awareness and experience regarding the use of GPR in civil engineering vary strongly across different European areas. The COST Action TU1208 is working hard on leveraging these differences, by sharing and disseminating knowledge and experience, as well as by developing guidelines and protocols for a safe and effective use of GPR in civil engineering. GPR users need to know which is the best way to conduct GPR measurements and what the quality level for the results should be. The TU1208 guidelines will ensure a higher efficiency and quality of GPR services and they will constitute a scientific basis for the introduction of European Standards on the application of GPR in civil engineering. The aim of this contribution is to present an in-depth overview and critical analysis of the existing GPR international and national standards and guidelines. The main documents considered in our work are listed and briefly described in the following. Three standards are provided by the American Society for Testing and Materials (ASTM), to guide the GPR use for subsurface investigation, evaluation of asphalt-covered concrete bridge decks, and determination of pavement-layer thickness: 1.

    2018-04-01

    This paper deals with the stability analysis of internally damped rotating composite shafts. An Euler-Bernoulli shaft finite element formulation based on Equivalent Single Layer Theory (ESLT), including the hysteretic internal damping of composite material and transverse shear effects, is introduced and then used to evaluate the influence of various parameters: stacking sequences, fiber orientations and bearing properties on natural frequencies, critical speeds, and instability thresholds. The obtained results are compared with those available in the literature using different theories. The agreement in the obtained results show that the developed Euler-Bernoulli finite element based on ESLT including hysteretic internal damping and shear transverse effects can be effectively used for the stability analysis of internally damped rotating composite shafts. Furthermore, the results revealed that rotor stability is sensitive to the laminate parameters and to the properties of the bearings.

    Full Text Available Unifying the economical-financial information at an international level represents today, within the context of the globalization and integration of the financial markets around the world, an important and urgent demand. One of the coordinates of accounting globalization is the fair value based valuation system. This tendency arises from the contents of international accounting standards and from the progress of world-wide regulating practice. The economic and market events of the past years have highlighted the importance of fair value measurements used in financial statements and have emphasized the need for consistency and comparability in those measurements infinancial statements prepared around the globe.

    2018-04-01

    A growing number of statistical analyses are being developed for single-case research. One important factor in evaluating these methods is the extent to which each corresponds to visual analysis. Few studies have compared statistical and visual analysis, and information about more recently developed statistics is scarce. Therefore, our purpose was to evaluate the agreement between visual analysis and four statistical analyses: improvement rate difference (IRD); Tau-U; Hedges, Pustejovsky, Shadish (HPS) effect size; and between-case standardized mean difference (BC-SMD). Results indicate that IRD and BC-SMD had the strongest overall agreement with visual analysis. Although Tau-U had strong agreement with visual analysis on raw values, it had poorer agreement when those values were dichotomized to represent the presence or absence of a functional relation. Overall, visual analysis appeared to be more conservative than statistical analysis, but further research is needed to evaluate the nature of these disagreements.

    Prior studies of modern scientific internationalism have been written primarily from the point of view of scientists, with little regard to the influence of the state. This study examines the state's role in international scientific relations. States sometimes encouraged scientific internationalism; in the mid-twentieth century, they often sought to restrict it. The present study examines state involvement in international scientific congresses, the primary intersection between the national and international dimensions of scientists' activities. Here we examine three comparative instances in which such restrictions affected scientific internationalism: an attempt to bring an international aerodynamics congress to Nazi Germany in the late 1930s, unsuccessful efforts by Soviet geneticists to host the Seventh International Genetics Congress in Moscow in 1937, and efforts by U.S. scientists to host international meetings in 1950s cold war America. These case studies challenge the classical ideology of scientific internationalism, wherein participation by a nation in a scientist's fame spares the scientist conflict between advancing his science and advancing the interests of his nation. In the cases we consider, scientists found it difficult to simultaneously support scientific universalism and elitist practices. Interest in these congresses reached the top levels of the state, and access to patronage beyond state control helped determine their outcomes.

  14. An analysis of international nuclear fuel supply options

    Science.gov (United States)

    Taylor, J'tia Patrice

    As the global demand for energy grows, many nations are considering developing or increasing nuclear capacity as a viable, long-term power source. To assess the possible expansion of nuclear power and the intricate relationships---which cover the range of economics, security, and material supply and demand---between established and aspirant nuclear generating entities requires models and system analysis tools that integrate all aspects of the nuclear enterprise. Computational tools and methods now exist across diverse research areas, such as operations research and nuclear engineering, to develop such a tool. This dissertation aims to develop methodologies and employ and expand on existing sources to develop a multipurpose tool to analyze international nuclear fuel supply options. The dissertation is comprised of two distinct components: the development of the Material, Economics, and Proliferation Assessment Tool (MEPAT), and analysis of fuel cycle scenarios using the tool. Development of MEPAT is aimed for unrestricted distribution and therefore uses publicly available and open-source codes in its development when possible. MEPAT is built using the Powersim Studio platform that is widely used in systems analysis. MEPAT development is divided into three modules focusing on: material movement; nonproliferation; and economics. The material movement module tracks material quantity in each process of the fuel cycle and in each nuclear program with respect to ownership, location and composition. The material movement module builds on techniques employed by fuel cycle models such as the Verifiable Fuel Cycle Simulation (VISION) code developed at the Idaho National Laboratory under the Advanced Fuel Cycle Initiative (AFCI) for the analysis of domestic fuel cycle. Material movement parameters such as lending and reactor preference, as well as fuel cycle parameters such as process times and material factors are user-specified through a Microsoft Excel(c) data spreadsheet

  15. Vibration behavior of PWR reactor internals Model experiments and analysis

    1975-01-01

    In the late 1971, the CEA and FRAMATOME decided to undertake a comprehensive joint program of studying the vibration behavior of PWR internals of the 900 MWe, 50 cycle, 3 loop reactor series being built by FRAMATOME in France. The PWR reactor internals are submitted to several sources of excitation during normal operation. Two main sources of excitation may effect the internals behavior: the large flow turbulences which could generate various instabilities such as: vortex shedding: the pump pressure fluctuations which could generate acoustic noise in the circuit at frequencies corresponding to shaft speed frequencies or blade passing frequencies, and their respective harmonics. The flow induced vibrations are of complex nature and the approach selected, for this comprehensive program, is semi-empirical and based on both theoretical analysis and experiments on a reduced scale model and full scale internals. The experimental support of this program consists of: the SAFRAN test loop which consists of an hydroelastic similitude of a 1/8 scale model of a PWR; harmonic vibration tests in air performed on full scale reactor internals in the manufacturing shop; the GENNEVILLIERS facilities which is a full flow test facility of primary pump; the measurements carried out during start up on the Tihange reactor. This program will be completed in April 1975. The results of this program, the originality of which consists of studying separately the effects of random excitations and acoustic noises, on the internals behavior, and by establishing a comparison between experiments and analysis, will bring a major contribution for explaining the complex vibration phenomena occurring in a PWR

    Oceanic top predators have ecological, social and economic value of global significance. These wide-ranging marine species, which include sharks, tunas and billfishes, marine mammals, turtles and seabirds, are the focus of international research attention under the Climate Impacts on Oceanic Top Predators (CLIOTOP) science programme, one of the Integrated Marine Biosphere Research (IMBeR) projects. Over more than a decade, research conducted under CLIOTOP has involved scientists from more than 30 countries, with international collaboration increasing markedly over time, and comparative analyses resulting in new knowledge and understanding of oceanic top predators. This special issue presents 27 papers arising from the 3rd CLIOTOP symposium, held in San Sebastián, Spain in September 2015, spanning topics such as conservation biology, trophic ecology, fisheries science, climate change, and adaptive management. The maturation and synthesis of CLIOTOP's collaborative research is now resulting in real-world management applications and improving understanding of potential ecological and socio-economic impacts of climate change in oceanic systems. The ultimate CLIOTOP goal of preparing both climate-sensitive predator populations and the human societies dependent on them for the impending impacts of climate change is now within reach.

    In the present study, six kinds of major equipment of a typical reactor internals were identified by incorporating recent research trend. Based on this, detailed numerical models were developed and used for establishment of optimum analysis methodology subjected to hydrodynamic loads. As a result, stress values of the major equipment were calculated through the acoustic-structure analysis under periodic hydrodynamic load and the turbulence-structure analysis under random hydrodynamic load. The numerical analysis scheme can be used for development of preventive action plan and management procedures of the reactor internals. Reactor internals installed in a pressure vessel have been exposed to harsh environment such as high neutron irradiation and temperature with complex fluid flow. As the increase of operational years of NPPs(Nuclear Power Plants), possibility of functional loss of the reactor internals is increased due to degradation caused by radiation embrittlement, thermal aging, fatigue, corrosion and FIV(Flow-Induced Vibration) etc. In practice, defects were detected at core support structure as well as upper and lower parts of structural assembly in European and United States NPPs. Recently, in a GALL(Generic Aging Lessons Learned) report, US NRC(Nuclear Regulatory Commission) identified reactor internals as a high priority component and addressed relevant management programs. In Korea, similar activities have been conducted for long-term operation beyond design lifetime but most of them were limited to qualitative evaluation based on examination and maintenance programs. Therefore, not only to reduce repair and replacement efforts but also to secure the stability of NPPs, necessity for development of quantitative evaluation technique as well as establishment of preventive action plan and management procedures is on the rise. The FIV represents the structural vibration phenomenon induced by liquid flow and generally occurs at contact surfaces. In the present

    Social inclusion of people with mental health issues is an aim of the World Health Organisation. Many countries have adopted that objective, including Brazil and the United Kingdom and both have focused treatment in the community. The aim of this article is to compare international results using the same inclusion instrument. The samples in this study were 225 people with mental health issues in community services in São Paulo, Brazil. Their results are compared to findings from 168 people with similar mental health issues in Hong Kong, China, and from the United Kingdom - a nationally representative sample of 212 people without mental health issues. The instrument used to measure a social inclusion called Social and Communities Opportunities Profile (SCOPE) has been validated for use in the United Kingdom, China and Brazil. The results are that people with mental health issues have worse social inclusion when compared to general population. Between the people with mental health issues, the sample of São Paulo has the lowest social inclusion index but, in relation to access to the Brazilian revised mental health services, that sample has a similarly high inclusion rating to the general population of the United Kingdom. Findings are important to understand mental health in the community context, as well as their adversities and potentialities.

    While all non-proliferation, arms control and disarmament (NACD) regimes must address the issue of information management, this area has remained an under-explored part of the arms control field. This paper compares information management processes across a variety of NACD regimes for the purpose of identifying potential synergies between regimes and suggesting means by which to strengthen future arms control verification efforts. The paper explores the information management systems of the International Atomic Energy Agency (IAEA), the United Nations Special Commission in Iraq (UNSCOM), the Conventional Forces in Europe Agreement (CFE), and the Comprehensive Test Ban Treaty (CTBT).

    In the deterministic design basis analysis of the United Kingdom (UK) EPR based nuclear power plants all postulated initiating events are grouped into two different types, internal faults and internal/external hazards. ''Internal Fires'' is one of the internal hazards analysed at the design stage of the UK EPR. In effect, the main safety objective for fire protection is to ensure that all the required safety functions are performed in the event of an internal fire. To achieve this safety objective, provisions for protection against fire risks are taken to: (i) limit the spread of a fire, protect the safety functions of the facility; (ii) limit the propagation of smoke and dispersion of toxic, radioactive, inflammable, corrosive or explosive materials, and (iii) ensure the achievement of a safe shutdown state, personnel evacuation and all other necessary emergency actions. This paper presents the UK EPR approach on how the above provisions are applied. Such provisions involve implementing means of fire prevention, surveillance, firefighting and limiting fire consequences, appropriate to the risks inherent to the facility. Overall, the design of the UK EPR fire protection systems is based on three types of measures: prevention, containment and control.

    Comparative analysis of multiple genomes of closely or distantly related Drosophila species undoubtedly creates excitement among evolutionary biologists in exploring the genomic changes with an ecology and evolutionary perspective. We present herewith the de novo assembled whole genome sequences of four Drosophila species, D. bipectinata, D. takahashii, D. biarmipes and D. nasuta of Indian origin using Next Generation Sequencing technology on an Illumina platform along with their detailed assembly statistics. The comparative genomics analysis, e.g. gene predictions and annotations, functional and orthogroup analysis of coding sequences and genome wide SNP distribution were performed. The whole genome of Zaprionus indianus of Indian origin published earlier by us and the genome sequences of previously sequenced 12 Drosophila species available in the NCBI database were included in the analysis. The present work is a part of our ongoing genomics project of Indian Drosophila species.

    The dissolved air flotation (DAF) system is a water treatment process that removes contaminants by attaching micro bubbles to them, causing them to float to the water surface. In the present study, two-phase flow of air-water mixture is simulated to investigate changes in the internal flow analysis of DAF systems caused by using different turbulence models. Internal micro bubble distribution, velocity, and computation time are compared between several turbulence models for a given DAF geometry and condition. As a result, it is observed that the standard κ-ε model, which has been frequently used in previous research, predicts somewhat different behavior than other turbulence models

The scope of the comparison includes the elements of the relevant legislations, the regulatory system and processes including the core functions of the regulatory body (authorization, review and assessment, inspection and enforcement, development of regulations and guides); and the staffing and training of regulatory body. The respective availabe data of the Malaysian and Philippine regulatory infrastructures and current practices were gathered and analyzed. Recommendations to fill the gaps and strengthen the existing regulatory infrastructure of each country was given using as bases relevant IAEA safety guides. Based on the analysis made, the main findings are: the legislations of both countries do not contain al the elements of teh national policy and strategy for safety as well as those of teh framework for safety in GR Part I. Among the provision that need to be included in the legislations are: emergency planning and response; decommissioning of facilities safe management of radioactive wastes and spent fuel; competence for safety; and technical sevices. Provisions on coordination of different authorities with safety responsibilities within the regulatory framework for safety as well as liaison with advisory bodies and support organizations need to be enhanced. The Philippines needs to establish an independent regulatory body, ie. separate from organizations charged with promotion of nuclear technologies and responsible for facilitiesand activities.

    TNF-α regulates immune cells and acts as an endogenous pyrogen. Reverse transcription polymerase chain reaction (RT-PCR) is one of the most commonly used methods for gene expression analysis. Among the alternatives to PCR, loop-mediated isothermal amplification (LAMP) shows good potential in terms of specificity and sensitivity. However, few studies have compared RT-PCR and LAMP for human gene expression analysis. Therefore, in the present study, we compared one-step RT-PCR, two-step RT-LAMP and one-step RT-LAMP for human gene expression analysis. We compared three gene expression analysis methods using the human TNF-α gene as a biomarker from peripheral blood cells. Total RNA from the three selected febrile patients were subjected to the three different methods of gene expression analysis. In the comparison of three gene expression analysis methods, the detection limit of both one-step RT-PCR and one-step RT-LAMP were the same, while that of two-step RT-LAMP was inferior. One-step RT-LAMP takes less time, and the experimental result is easy to determine. One-step RT-LAMP is a potentially useful and complementary tool that is fast and reasonably sensitive. In addition, one-step RT-LAMP could be useful in environments lacking specialized equipment or expertise.

    The benefit of increasing genomic sequence data to the scientific community depends on easy-to-use, scalable bioinformatics support. CloVR-Comparative combines commonly used bioinformatics tools into an intuitive, automated, and cloud-enabled analysis pipeline for comparative microbial genomics. CloVR-Comparative runs on annotated complete or draft genome sequences that are uploaded by the user or selected via a taxonomic tree-based user interface and downloaded from NCBI. CloVR-Comparative runs reference-free multiple whole-genome alignments to determine unique, shared and core coding sequences (CDSs) and single nucleotide polymorphisms (SNPs). Output includes short summary reports and detailed text-based results files, graphical visualizations (phylogenetic trees, circular figures), and a database file linked to the Sybil comparative genome browser. Data up- and download, pipeline configuration and monitoring, and access to Sybil are managed through CloVR-Comparative web interface. CloVR-Comparative and Sybil are distributed as part of the CloVR virtual appliance, which runs on local computers or the Amazon EC2 cloud. Representative datasets (e.g. 40 draft and complete Escherichia coli genomes) are processed in genomics projects, while eliminating the need for on-site computational resources and expertise.

    An important issue in public policy debates is the effect of international migration on welfare in source and host countries. We address this issue by constructing a general equilibrium model of a two-class source or host country. Each country produces many traded and non-traded goods, uses income taxes and distributes the tax receipts equally to all individuals. The analysis examines the effects of permanent migration on class, and national welfare. We show, among other things, that marginal...

    Tumoural portal vein thrombosis (PVT) is a major prognostic factor in hepatocellular carcinoma (HCC). The efficacy of sorafenib, the only treatment approved at an advanced stage, is limited. Based on previous data, selective internal radiation therapy (SIRT), or {sup 90}Y radioembolization, seems an interesting option. We aimed to compare both treatments in this population. We retrospectively compared patients treated in two centres for HCC with tumoural PVT. We compared overall survival (OS) between patients treated with SIRT and patients treated with sorafenib. Analyses were performed before and after 1:1 matching with a propensity score for controlling indication bias, using a Cox proportional hazards model. A total of 151 patients were analysed, 34 patients treated with SIRT and 117 patients treated with sorafenib only. In the whole population, SIRT was associated with a higher median OS as compared with sorafenib: 18.8 vs 6.5 months (log-rank p < 0.001). There was an imbalance of baseline characteristics between patients treated by SIRT and sorafenib, which justified patient matching with use of a propensity score: 24 patients treated with SIRT could be matched with 24 patients treated with sorafenib. OS was estimated with a median of 26.2 vs 8.7 months in patients treated with SIRT vs sorafenib, respectively (log-rank p = 0.054). Before and after patient matching, the adjusted hazard ratio related to treatment by SIRT was estimated at 0.62 [95 % confidence interval (CI) 0.39-0.97] (p = 0.037) and 0.40 (95 % CI 0.19-0.82) (p = 0.013), respectively. SIRT seems more effective than sorafenib in patients presenting with HCC and tumoural PVT. This hypothesis is being tested in prospective randomized trials. (orig.)

    In prokaryotic genomes, functionally coupled genes can be organized in conserved gene clusters enabling their coordinated regulation. Such clusters could contain one or several operons, which are groups of co-transcribed genes. Those genes that evolved from a common ancestral gene by speciation (i.e. orthologs) are expected to have similar genomic neighborhoods in different organisms, whereas those copies of the gene that are responsible for dissimilar functions (i.e. paralogs) could be found in dissimilar genomic contexts. Comparative analysis of genomic neighborhoods facilitates the prediction of co-regulated genes and helps to discern different functions in large protein families. We intended, building on the attribution of gene sequences to the clusters of orthologous groups of proteins (COGs), to provide a method for visualization and comparative analysis of genomic neighborhoods of evolutionary related genes, as well as a respective web server. Here we introduce the COmparative Gene Neighborhoods Analysis Tool (COGNAT), a web server for comparative analysis of genomic neighborhoods. The tool is based on the COG database, as well as the Pfam protein families database. As an example, we show the utility of COGNAT in identifying a new type of membrane protein complex that is formed by paralog(s) of one of the membrane subunits of the NADH:quinone oxidoreductase of type 1 (COG1009) and a cytoplasmic protein of unknown function (COG3002).

    Comparative analysis is used throughout biology. When entities under comparison (e.g. proteins, genomes, species) are related by descent, evolutionary theory provides a framework that, in principle, allows N-ary comparisons of entities, while controlling for non-independence due to relatedness. Powerful software tools exist for specialized applications of this approach, yet it remains under-utilized in the absence of a unifying informatics infrastructure. A key step in developing such an infrastructure is the definition of a formal ontology. The analysis of use cases and existing formalisms suggests that a significant component of evolutionary analysis involves a core problem of inferring a character history, relying on key concepts: "Operational Taxonomic Units" (OTUs), representing the entities to be compared; "character-state data" representing the observations compared among OTUs; "phylogenetic tree", representing the historical path of evolution among the entities; and "transitions", the inferred evolutionary changes in states of characters that account for observations. Using the Web Ontology Language (OWL), we have defined these and other fundamental concepts in a Comparative Data Analysis Ontology (CDAO). CDAO has been evaluated for its ability to represent token data sets and to support simple forms of reasoning. With further development, CDAO will provide a basis for tools (for semantic transformation, data retrieval, validation, integration, etc.) that make it easier for software developers and biomedical researchers to apply evolutionary methods of inference to diverse types of data, so as to integrate this powerful framework for reasoning into their research.

    The first Finnish sentence-based speech test in noise--the Finnish matrix sentence test--was recently developed. The aim of this study was to determine the characteristics of the new test with respect to test-retest reliability, speech recognition curve, and international comparability in Finnish cochlear implant (CI) recipients. The speech reception thresholds (SRT) were measured by means of an adaptive test procedure and compared with the results of the traditional Finnish word test. Additional measurements for concurrent slope and SRT estimation were conducted to determine the speech recognition curve and to check the test-retest reliability. The measurements were performed on 78 Finnish CI recipients. In a subset of 25 patients, additional measurements for test-retest reliability and slope determination were performed. The mean SRT was -3.5 ± 1.7 dB SNR, with only a weak correlation with the Finnish word test. Test-retest reliability was within ± 1 dB and the mean slope of the speech recognition curve was 14.6 ± 3.6 %/dB. The rehabilitation results were similar to the results published for the German matrix test. The Finnish matrix test was found to be suitable and efficient in CI recipients with similar characteristics as the German matrix test.

    The qualitative and quantitative chemical analysis with Neutron Activation Analysis (NAA) is an importance utilization of a nuclear research reactor, and this should be accelerated and promoted in application and its development to raise the utilization of the reactor. The application of Comparative NAA technique in GA Siwabessy Multi Purpose Reactor (RSG-GAS) needs special (not commercially available yet) soft wares for analyzing the spectrum of multiple elements in the analysis at once. The application carried out using a single spectrum software analyzer, and comparing each result manually. This method really degrades the quality of the analysis significantly. To solve the problem, a computer code was designed and developed for comparative NAA. Spectrum analysis in the code is carried out using a non-linear fitting method. Before the spectrum analyzed, it was passed to the numerical filter which improves the signal to noise ratio to do the deconvolution operation. The software was developed using the G language and named as PASAN-K The testing result of the developed software was benchmark with the IAEA spectrum and well operated with less than 10 % deviation

    Full Text Available Analysis of the internal music in Sahifeh Sajjadiyyeh Hasan Khalaf * Marziye Abad ** Seyed Hosseyn Seyedi *** Balasem mohseni **** Abstract Considering the fact that music is not just specific to poetry but it exists in all literary works, whether poetry or prose, this study attempts to examine the inner function of the music in the Sahifah Sajadieh. External music is related to the prosodic rhythms and rhymes, but the internal music relates to the Ayqa and rhythm through the repetition of letters and words, pun, balance and matched sentences in the words. Words of Imam Sajjad in Sahifeh have internal music which is highly excellent and outstanding. This internal music is created through repeated words, sentence repetition, and puns, returning the second hemistich to first hemistich, assonance and rhyme scheme. And literary techniques led to the creation of a musical space that is separate from the meaning of the word and is not part of the meaning of the word. Hence, this paper examines the main sources of local music in the Sahifah Sajadieh. Our approach in this paper is descriptive – analytical. We seek to explain the role of oratory skills in musical prose to explain the aesthetic value and music in Sahifeh Sajadieh. Keywords: Sahifeh Sajadieh, Music, technique of Repeat, Rhetorics.

    Seismic analysis of complex and large structures, consisting of thick shear walls, such as Reactor Building is very involved and time consuming. It is a standard practice to model the structure as a stick model to predict reasonably the dynamic behaviour of the structure. It is required to determine approximate equivalent sectional properties of Internal Structure for representation in the stick model. The restraint to warping can change the stress distribution thus affecting the centre of rigidity and torsional inertia, Hence, standard formulae does not hold good for determination of sectional properties of the Internal Structure. In this case the equivalent sectional properties for the Internal Structure are calculated using a Finite Element Model (FEM) of the Internal Structure and applying unit horizontal forces in each direction. A 3-D stick model is developed using the guidelines. Using the properties calculated by FEM and also by standard formulae, the responses of the 3-D stick model are compared. (J.P.N.)

    During the past decade, the development of high throughput nucleic sequencing and mass spectrometry analysis techniques have enabled the characterization of microbial communities through metagenomics, metatranscriptomics, metaproteomics and metabolomics data. To reveal the diversity of microbial communities and interactions between living conditions and microbes, it is necessary to introduce comparative analysis based upon integration of all four types of data mentioned above. Comparative meta-omics, especially comparative metageomics, has been established as a routine process to highlight the significant differences in taxon composition and functional gene abundance among microbiota samples. Meanwhile, biologists are increasingly concerning about the correlations between meta-omics features and environmental factors, which may further decipher the adaptation strategy of a microbial community. We developed a graphical comprehensive analysis software named MetaComp comprising a series of statistical analysis approaches with visualized results for metagenomics and other meta-omics data comparison. This software is capable to read files generated by a variety of upstream programs. After data loading, analyses such as multivariate statistics, hypothesis testing of two-sample, multi-sample as well as two-group sample and a novel function-regression analysis of environmental factors are offered. Here, regression analysis regards meta-omic features as independent variable and environmental factors as dependent variables. Moreover, MetaComp is capable to automatically choose an appropriate two-group sample test based upon the traits of input abundance profiles. We further evaluate the performance of its choice, and exhibit applications for metagenomics, metaproteomics and metabolomics samples. MetaComp, an integrative software capable for applying to all meta-omics data, originally distills the influence of living environment on microbial community by regression analysis

    Full Text Available Background. Several international groups develop asthma guidelines. Conflicting recommendations across guidelines have been described in several disease areas and may contribute to practice variability. Accordingly, we compared the latest Canadian Thoracic Society (CTS asthma guideline with contemporaneous international asthma guidelines to evaluate conflicting recommendations and their causes. Methods. We identified the latest CTS asthma guideline update (2012 and the following societies which also updated their guidelines in 2012: the British Thoracic Society and Scottish Intercollegiate Guidelines Network and the Global Initiative for Asthma. We compared these three guidelines on (1 key methodological factors and (2 adult pharmacotherapy recommendations. Results. Methods used and documentation provided for literature search strategy and dates, evidence synthesis, outcomes considered, evidence appraisal, and recommendation formulation varied between guidelines. Criteria used to define suboptimal asthma control varied widely between guidelines. Inhaled corticosteroid dosing recommendations diverged, as did recommendations surrounding use of budesonide/formoterol as a reliever and controller and recommendations in the subsequent step. Conclusions. There are important differences between recommendations provided in contemporaneous asthma guidelines. Causes include differences in methods used for interpreting evidence and formulating recommendations. Adopting a common set of valid and explicit methods across international societies could harmonize recommendations and facilitate guideline implementation.

    Full Text Available The fact that gastric surgery is at the moment the most effective treatment to fight against obesity highlights the relevance of gastric derived proteins as potential targets to treat this pathology. Taking advantage of a previously established gastric explant model for endocrine studies, the proteomic analysis of gastric secretome was performed. To validate this gastric explant system for proteomic analysis, the identification of ghrelin, a classical gastric derived peptide, was performed by MS. In addition, the differential analysis of gastric secretomes under differential nutritional status (control feeding vs fasting vs re-feeding was performed. The MS identified proteins are showed in the present manuscript. The data supplied in this article is related to the research article entitled “Comparative secretome analysis of rat stomach under different nutritional status” [1].

    2009-09-01

    Full Text Available Since 2000, a number of parliaments and governments have introduced electronic petitions systems (e-petitions. Compared to most other means of e-participation made available by public institutions, e-petitions have moved beyond the experimental stage and are characterized by a high level of institutionalization and procedural maturity. Hence, the field of e-petitioning is particularly promising if the relationship between public institutions and Internet-based participation channels is to be better understood. Based on empirical data generated in the research project "Public electronic petitions and civic involvement" conducted on behalf of the German Bundestag, the article undertakes an analysis of the e-petition systems of the Scottish Parliament, the Parliament of Queensland, the Bundestag and the Norwegian Municipalities in comparative perspective. Apart from presenting the systems’ main technical and procedural features and selected user statistics, the article attempts to explain the high attractiveness of e-petitions for parliaments and governments.

    Many guidelines and regulations allow children and adolescents to be enrolled in research without the prospect of clinical benefit when it poses minimal risk. However, few systematic methods exist to determine when research risks are minimal. This situation has led to significant variation in minimal risk judgments, raising concern that some children are not being adequately protected. To address this concern, we describe a new method for implementing the widely endorsed "risks of daily life" standard for minimal risk. This standard defines research risks as minimal when they do not exceed the risks posed by daily life activities or routine examinations. This study employed a conceptual and normative analysis, and use of an illustrative example. Different risks are composed of the same basic elements: Type, likelihood, and magnitude of harm. Hence, one can compare the risks of research and the risks of daily life by comparing the respective basic elements with each other. We use this insight to develop a systematic method, direct comparative analysis, for implementing the "risks of daily life" standard for minimal risk. The method offers a way of evaluating research procedures that pose the same types of risk as daily life activities, such as the risk of experiencing anxiety, stress, or other psychological harm. We thus illustrate how direct comparative analysis can be applied in practice by using it to evaluate whether the anxiety induced by a respiratory CO2 challenge poses minimal or greater than minimal risks in children and adolescents. Direct comparative analysis is a systematic method for applying the "risks of daily life" standard for minimal risk to research procedures that pose the same types of risk as daily life activities. It thereby offers a method to protect children and adolescents in research, while ensuring that important studies are not blocked because of unwarranted concerns about research risks.

    The purpose of this study is to compare the WoS with a national Chinese bibliometric database at the level of individual authors and measure the extent of the overlap of the group of authors that are the most active in the two data sources. The results indicate that Chinese scholars do not have homogeneous publication patterns: some very productive scholars mostly publish in international (WoS) journals while others prefer to diffuse their research results in national Chinese journals. Disciplines that are most international in scope exhibit a much higher level of overlap than those of the social sciences and humanities. These results suggest that the WoS does not accurately represent Chinese research activities, especially in social science and humanities, but that it also has a relative overlap with the Chinese national scientific literature in the natural and medical sciences.

    To suggest a scheme of decision making on pricing for medicines that are part of Free Regulated Regime, a regulation way of the pharmaceutical pricing policy in Colombia. It includes two regulation tools: international reference prices and a cost minimization analysis methodology. Following the current pricing policy, international reference prices were built with data from five countries for selected medicines, which are under Free Regulated Regime. The cost minimization analysis methodology includes selection of those medicines under Free Regulated Regime with possible comparable medicines, selection of comparable medicines, and treatment costs evaluation. As a result of the estimate of International Reference Prices, four medicines showed in the domestic pharmaceutical market a bigger price than the Reference Price. A scheme of decision-making was design containing two possible regulation tools for medicines that are part of Free Regulated Regime: estimate of international reference prices and cost minimization analysis methodology. This diagram would be useful to assist the pricing regulation of Free Regulated Regime in Colombia. As present results shows, international reference prices make clear when domestic prices are higher than those of reference countries. In the current regulation of pharmaceutical prices in Colombia, the international reference price has been applied for four medicines. Would be suitable to extend this methodology to other medicines of high impact on the pharmaceutical expenditure, in particular those covered by public funding. The availability of primary sources about treatment costs in Colombia needs to be improved as a requirement to develop pharmaco-economic evidence. SISMED is an official database that represents an important primary source of medicines prices in Colombia. Nevertheless, having into account that SISMED represents an important advantage of transparency in medicines prices, it needs to be improved in quality and data

Network meta-analyses published after January 2012 that compared at least five treatments and included at least 20 RCTs. Clinical experts were asked to identify in each network the treatment comparison of greatest clinical interest. Comparisons were excluded for which direct and indirect evidence disagreed, based on side, or node, splitting test (Pmeta-analyses were performed for each selected comparison. Monitoring boundaries of statistical significance were constructed and the evidence against the null hypothesis was considered to be strong when the monitoring boundaries were crossed. A significance level was defined as α=5%, power of 90% (β=10%), and an anticipated treatment effect to detect equal to the final estimate from the network meta-analysis. The frequency and time to strong evidence was compared against the null hypothesis between pairwise and network meta-analyses. 49 comparisons of interest from 44 networks were included; most (n=39, 80%) were between active drugs, mainly from the specialties of cardiology, endocrinology, psychiatry, and rheumatology. 29 comparisons were informed by both direct and indirect evidence (59%), 13 by indirect evidence (27%), and 7 by direct evidence (14%).

    ' interests, in that the turn-around time for assessments must be minimized, transparency must be maximized, the process must be considered fair using universally agreed standards and the process must be modifiable based on stakeholders' requirements; (ii) the assessment of medical technologies other than drugs may present different challenges and is managed separately in other HTA organizations; (iii) because of the link between HTA and reimbursement decisions, completion of the HTA process following regulatory approval can delay market access to new technologies, thus closer integration between regulatory approval and HTA processes is being explored internationally; (iv) there is a direct or indirect link to reimbursement in the jurisdictions explored - without this link the role of CER in the US will remain advisory; (v) each jurisdiction reviewed benefits from a single payer that is informed by the process - given the diverse multipayer environment in the US, CER in the US may usefully focus on generating comparative effectiveness evidence; (vi) a common metric for assessing intended and unintended effects of treatment allows comparison across different technologies; and (vii) one stated focus of CER is on therapeutic benefit among 'high-priority populations', including specific demographic groups (the elderly and children, racial and ethnic minorities) and individuals with disabilities, multiple chronic conditions and specific genomic factors. This will be difficult to achieve because epidemiological evidence of differences in therapeutic benefit among subgroups is detected through effect modification, or more specifically, statistical evidence of effect measure modification, typically on relative measures of effect. Few randomized trials have enough power to detect effect modification and these have been uncommon in the scientific literature. As consideration is given to the development of a publicly funded CER body in the US, much can be learned from the international

    Factors such as an external focus of attention (EF) and augmented feedback (AF) have been shown to improve performance. However, the efficacy of providing AF to enhance motor performance has never been compared with the effects of an EF or an internal focus of attention (IF). Therefore, the aim of the present study was to identify which of the three conditions (AF, EF or IF) leads to the highest performance in a countermovement jump (CMJ). Nineteen volunteers performed 12 series of 8 maximum CMJs. Changes in jump height between conditions and within the series were analysed. Jump heights differed between conditions (P jump heights at the end of the series in AF (+1.60%) and lower jump heights at the end of the series in EF (-1.79%) and IF (-1.68%) were observed. Muscle activity did not differ between conditions. The differences between conditions and within the series provide evidence that AF leads to higher performance and better progression within one series than EF and IF. Consequently, AF seems to outperform EF and IF when maximising jump height.

    Cell and tissue-based products, such as autologous adult stem cells, are being prescribed by physicians across the world for diseases and illnesses that they have neither been approved for or been demonstrated as safe and effective in formal clinical trials. These doctors often form part of informal transnational networks that exploit differences and similarities in the regulatory systems across geographical contexts. In this paper, we examine the regulatory infrastructure of five geographically diverse but socio-economically comparable countries with the aim of identifying similarities and differences in how these products are regulated and governed within clinical contexts. We find that while there are many subtle technical differences in how these regulations are implemented, they are sufficiently similar that it is difficult to explain why these practices appear more prevalent in some countries and not in others. We conclude with suggestions for how international governance frameworks might be improved to discourage the exploitation of vulnerable patient populations while enabling innovation in the clinical application of cellular therapies.

    This study assessed the performance of different single-stage continuous aerated submerged membrane bioreactors (MBR) for nitrogen removal. Almost complete nitrification was achieved in each MBR irrespective of operating mode and biomass system. Denitrification was found to be the rate-limiting step for total nitrogen (T-N) removal. The MBR with internal-loop airlift reactor (ALR) configuration performed better as regards T-N removal compared with continuous stirred-tank reactor (CSTR). It was demonstrated that simultaneous nitrification and denitrification (SND) is the mechanism leading to nitrogen removal and the contribution of microenvironment on SND is more remarkable for the MBRs with hybrid biomass. Macroenvironment analyses showed that gradient distribution of dissolved oxygen (DO) level in airlift MBRs imposed a significant effect on SND. Higher mixed liquor suspended solid (MLSS) concentration led to the improvement in T-N removal by enhancing anoxic microenvironment. Apparent nitrite accumulation coupled with higher nitrogen reduction was accomplished at MLSS concentration exceeded 12.6 g/L.

    Full Text Available Comparative analysis is used throughout biology. When entities under comparison (e.g. proteins, genomes, species are related by descent, evolutionary theory provides a framework that, in principle, allows N-ary comparisons of entities, while controlling for non-independence due to relatedness. Powerful software tools exist for specialized applications of this approach, yet it remains under-utilized in the absence of a unifying informatics infrastructure. A key step in developing such an infrastructure is the definition of a formal ontology. The analysis of use cases and existing formalisms suggests that a significant component of evolutionary analysis involves a core problem of inferring a character history, relying on key concepts: “Operational Taxonomic Units” (OTUs, representing the entities to be compared; “character-state data” representing the observations compared among OTUs; “phylogenetic tree”, representing the historical path of evolution among the entities; and “transitions”, the inferred evolutionary changes in states of characters that account for observations. Using the Web Ontology Language (OWL, we have defined these and other fundamental concepts in a Comparative Data Analysis Ontology (CDAO. CDAO has been evaluated for its ability to represent token data sets and to support simple forms of reasoning. With further development, CDAO will provide a basis for tools (for semantic transformation, data retrieval, validation, integration, etc. that make it easier for software developers and biomedical researchers to apply evolutionary methods of inference to diverse types of data, so as to integrate this powerful framework for reasoning into their research.

    2012-01-01

    In this work we presented a comparative analysis of the mitochondrial genomes in gastropods. Nucleotide and amino acids composition was calculated and a comparative visual analysis of the start and termination codons was performed. The organization of the genome was compared calculating the number of intergenic sequences, the location of the genes and the number of reorganized genes (breakpoints) in comparison with the sequence that is presumed to be ancestral for the group. In order to calculate variations in the rates of molecular evolution within the group, the relative rate test was performed. In spite of the differences in the size of the genomes, the amino acids number is conserved. The nucleotide and amino acid composition is similar between Vetigastropoda, Ceanogastropoda and Neritimorpha in comparison to Heterobranchia and Patellogastropoda. The mitochondrial genomes of the group are very compact with few intergenic sequences, the only exception is the genome of Patellogastropoda with 26,828 bp. Start codons of the Heterobranchia and Patellogastropoda are very variable and there is also an increase in genome rearrangements for these two groups. Generally, the hypothesis of constant rates of molecular evolution between the groups is rejected, except when the genomes of Caenogastropoda and Vetigastropoda are compared.

    Full Text Available Activity theory is a relevant framework for the Design field, and their graphic representations are cognitive artifacts that aid the understanding, use and communication of this theory. However, there is a lack of consistency around the graphics and labels used in these representations. Based on this, the aim of this study was to identify, analyze and evaluate these differences and propose a representation that aims to be more suitable for the theory. For this, uses as method a literature review based on Engeström (2001 and its three generations of visual models, combined with graphical analysis of representations collected in a hundred papers from international journals.

    Full Text Available To date, the Sociological Laboratory of the Peoples’ Friendship University of Russia has accumulated a vast experience in the field of cross-cultural studies reflected in the publications based on the results of mass surveys conducted in Moscow, Maikop, Beijing, Guangzhou, Prague, Belgrade, and Pristina. However, these publications mainly focus on the comparisons of the empirical data rather than methodological and technical issues, that is why the aim of this article is to identify key problems of the comparative analysis in cross-cultural studies that become evident only if you conduct an empirical research yourself - from the first step of setting the problem and approving it by all the sides (countries involved to the last step of interpreting and comparing the data obtained. The authors are sure that no sociologist would ever doubt the necessity and importance of comparative analysis in the broadest sense of the word, but at the same time very few are ready to discuss its key methodological challenges and prefer to ignore them completely. We summarize problems of the comparative analysis in sociology as follows: (1 applying research techniques to the sample in another country - both in translating and adapting them to different social realities and worldview (in particular, the problematic status of standardization and qualitative approach; (2 choosing “right” respondents to question and relevant cases (cultures to study; (3 designing the research scheme, i.e. justifying the sequence of steps (what should go first - methodology or techniques; (4 accepting the procedures that are correct within one country for cross-cultural work (whether or not that is an appropriate choice.

  11. F247. INTERNALIZED STIGMA HAS A STRONGER RELATIONSHIP WITH INTRINSIC MOTIVATION COMPARED TO AMOTIVATION IN EARLY PHASE AND PROLONGED SCHIZOPHRENIA

    Abstract Background Motivation deficits predict decreased functioning in schizophrenia. Recent work suggests deficits reflect challenges in separate domains: intrinsic motivation (one’s internal drive to engage in a behavior out of enjoyment or interest) and amotivation (one’s broader decrease in motivated behavior linked to avolition and anhedonia). Internalized stigma is another determinant of functioning for people with schizophrenia that may impact motivation. However, little is known about these relationships, including which aspects of motivation it may impact nor when these links emerge. Identifying the link between these constructs may help to identify whether internalized stigma may be a novel treatment target to facilitate improvements in motivation. Methods Forty adults with early phase schizophrenia and 66 adults with prolonged schizophrenia completed measures of internalized stigma, intrinsic motivation, and amotivation. Pearson’s correlations were examined followed by Fischer’s r-to-z transformations to compare differences in the magnitude of associations between internalized stigma and intrinsic motivation and internalized stigma and amotivation among the first episode and prolonged samples. Next, we conducted stepwise regressions to examine whether internalized stigma was associated with intrinsic motivation above and beyond associations with amotivation in each sample. Results In the early phase sample, the association between internalized stigma was greater with intrinsic motivation (r=-0.48, p=.00) compared to amotivation (r=0.27, p=0.10). Associations with internalized stigma in the prolonged sample were also greater with intrinsic motivation (r=-0.30, p=0.02) versus amotivation (r=0.19, p=0.12). The magnitude of the associations between internalized stigma and intrinsic motivation (z=1.03, p=0.15) and between internalized stigma and amotivation (z=0.41, p = 0.34) did not significantly differ when comparing phase of illness.

    Electronic medical records (EMR) offer a major potential for secondary use of data for research which can improve the safety, quality and efficiency of healthcare. They also enable the measurement of disease burden at the population level. However, the extent to which this is feasible in different countries is not well known. This study aimed to: 1) assess information governance procedures for extracting data from EMR in 16 countries; and 2) explore the extent of EMR adoption and the quality and consistency of EMR data in 7 countries, using management of diabetes type 2 patients as an exemplar. We included 16 countries from Australia, Asia, the Middle East, and Europe to the Americas. We undertook a multi-method approach including both an online literature review and structured interviews with 59 stakeholders, including 25 physicians, 23 academics, 7 EMR providers, and 4 information commissioners. Data were analysed and synthesised thematically considering the most relevant issues. We found that procedures for information governance, levels of adoption and data quality varied across the countries studied. The required time and ease of obtaining approval also varies widely. While some countries seem ready for secondary uses of data from EMR, in other countries several barriers were found, including limited experience with using EMR data for research, lack of standard policies and procedures, bureaucracy, confidentiality, data security concerns, technical issues and costs. This is the first international comparative study to shed light on the feasibility of extracting EMR data across a number of countries. The study will inform future discussions and development of policies that aim to accelerate the adoption of EMR systems in high and middle income countries and seize the rich potential for secondary use of data arising from the use of EMR solutions.

    Purpose: The midventilation (midV) approach can be used to take respiratory-induced pancreatic tumor motion into account during radiation therapy. In this study, the dosimetric consequences for organs at risk and tumor coverage of using a midV approach compared with using an internal target volume (ITV) were investigated. Methods and Materials: For each of the 18 patients, 2 treatment plans (25 × 2.0 Gy) were created, 1 using an ITV and 1 using a midV approach. The midV dose distribution was blurred using the respiratory-induced motion from 4-dimensional computed tomography. The resulting planning target volume (PTV) coverage for this blurred dose distribution was analyzed; PTV coverage was required to be at least V{sub 95%} >98%. In addition, the change in PTV size and the changes in V{sub 10Gy}, V{sub 20Gy}, V{sub 30Gy}, V{sub 40Gy}, D{sub mean} and D{sub 2cc} for the stomach and for the duodenum were analyzed; differences were tested for significance using the Wilcoxon signed-rank test. Results: Using a midV approach resulted in sufficient target coverage. A highly significant PTV size reduction of 13.9% (P<.001) was observed. Also, all dose parameters for the stomach and duodenum, except the D{sub 2cc} of the duodenum, improved significantly (P≤.002). Conclusions: By using the midV approach to account for respiratory-induced tumor motion, a significant PTV reduction and significant dose reductions to the stomach and to the duodenum can be achieved when irradiating pancreatic tumors.

    The authoritative contributions gathered in this volume reflect the state of the art in compositional data analysis (CoDa). The respective chapters cover all aspects of CoDa, ranging from mathematical theory, statistical methods and techniques to its broad range of applications in geochemistry, the life sciences and other disciplines. The selected and peer-reviewed papers were originally presented at the 6th International Workshop on Compositional Data Analysis, CoDaWork 2015, held in L’Escala (Girona), Spain. Compositional data is defined as vectors of positive components and constant sum, and, more generally, all those vectors representing parts of a whole which only carry relative information. Examples of compositional data can be found in many different fields such as geology, chemistry, economics, medicine, ecology and sociology. As most of the classical statistical techniques are incoherent on compositions, in the 1980s John Aitchison proposed the log-ratio approach to CoDa. This became the foundation...

    Tools of the theory of critical phenomena, namely the scaling analysis and universality, are argued to be applicable to large complex web-like network structures. Using a detailed analysis of the real data of the International Trade Network we argue that the scaled link weight distribution has an approximate log-normal distribution which remains robust over a period of 53 years. Another universal feature is observed in the power-law growth of the trade strength with gross domestic product, the exponent being similar for all countries. Using the 'rich-club' coefficient measure of the weighted networks it has been shown that the size of the rich-club controlling half of the world's trade is actually shrinking. While the gravity law is known to describe well the social interactions in the static networks of population migration, international trade, etc, here for the first time we studied a non-conservative dynamical model based on the gravity law which excellently reproduced many empirical features of the ITN

    Cristea, Gabriel; Constantinescu, Dan Mihai

    2018-02-01

    In practice, probability distributions are applied in such diverse fields as risk analysis, reliability engineering, chemical engineering, hydrology, image processing, physics, market research, business and economic research, customer support, medicine, sociology, demography etc. This article highlights important aspects of fitting probability distributions to data and applying the analysis results to make informed decisions. There are a number of statistical methods available which can help us to select the best fitting model. Some of the graphs display both input data and fitted distributions at the same time, as probability density and cumulative distribution. The goodness of fit tests can be used to determine whether a certain distribution is a good fit. The main used idea is to measure the "distance" between the data and the tested distribution, and compare that distance to some threshold values. Calculating the goodness of fit statistics also enables us to order the fitted distributions accordingly to how good they fit to data. This particular feature is very helpful for comparing the fitted models. The paper presents a comparison of most commonly used goodness of fit tests as: Kolmogorov-Smirnov, Anderson-Darling, and Chi-Squared. A large set of data is analyzed and conclusions are drawn by visualizing the data, comparing multiple fitted distributions and selecting the best model. These graphs should be viewed as an addition to the goodness of fit tests.

  19. Thermal mechanical analysis of applications with internal heat generation

    Science.gov (United States)

    Govindarajan, Srisharan Garg

    control blade, spatial variations in temperature within the control blade occur from the non-uniform heat generation within the BORAL as a result of the non-uniform thermal neutron flux along the longitudinal direction when the control blade is partially withdrawn. There is also variation in the heating profile through the thickness and about the circumferential width of the control blade. Mathematical curve-fits are generated for the non-uniform volumetric heat generation profile caused by the thermal neutron absorption and the functions are applied as heating conditions within a finite element model of the control blade built using the commercial finite element code Abaqus FEA. The finite element model is solved as a fully coupled thermal mechanical problem as in the case of the annular target. The resulting deflection is compared with the channel gap to determine if there is a significant risk of the control blade binding during reactor operation. Hence, this dissertation will consist of two sections. The first section will seek to present the thermal and structural safety analyses of the annular targets for the production of molybdenum-99. Since there hasn't been any detailed, documented, study on these annular targets in the past, the work complied in this dissertation will help to understand the thermal-mechanical behavior and failure margins of the target during in-vessel irradiation. As the work presented in this dissertation provides a general performance analysis envelope for the annular target, the tools developed in the process can also be used as useful references for future analyses that are specific to any reactor. The numerical analysis approach adopted and the analytical models developed, can also be applied to other applications, outside the Mo-99 project domain, where internal heat generation exists such as in electronic components and nuclear reactor control blades.

    Full Text Available Internalized weight stigma has gained growing interest due to its association with multiple health impairments in individuals with obesity. Especially high internalized weight stigma is reported by individuals undergoing bariatric surgery. For assessing this concept, two different self-report questionnaires are available, but have never been compared: the Weight Self-Stigma Questionnaire (WSSQ and the Weight Bias Internalization Scale (WBIS. The purpose of the present study was to provide and to compare reliability, convergent validity with and predictive values for psychosocial health outcomes for the WSSQ and WBIS.The WSSQ and the WBIS were used to assess internalized weight stigma in N = 78 prebariatric surgery patients. Further, body mass index (BMI was assessed and body image, quality of life, self-esteem, depression, and anxiety were measured by well-established self-report questionnaires. Reliability, correlation, and regression analyses were conducted.Internal consistency of the WSSQ was acceptable, while good internal consistency was found for the WBIS. Both measures were significantly correlated with each other and body image. While only the WSSQ was correlated with overweight preoccupation, only the WBIS was correlated with appearance evaluation. Both measures were not associated with BMI. However, correlation coefficients did not differ between the WSSQ and the WBIS for all associations with validity measures. Further, both measures significantly predicted quality of life, self-esteem, depression, and anxiety, while the WBIS explained significantly more variance than the WSSQ total score for self-esteem.Findings indicate the WSSQ and the WBIS to be reliable and valid assessments of internalized weight stigma in prebariatric surgery patients, although the WBIS showed marginally more favorable results than the WSSQ. For both measures, longitudinal studies on stability and predictive validity are warranted, for example, for weight

    This report documents work performed supporting the Department of Energy (DOE) Office of Nuclear Energy (NE) Fuel Cycle Technologies Used Fuel Disposition Campaign (UFDC) under work breakdown structure element 1.02.08.10, ST Analysis. In particular, this report fulfills the M4 milestone M4FT- 15OR0810036, Quantify effects of power uncertainty on fuel assembly characteristics, within work package FT-15OR081003 ST Analysis-ORNL. This research was also supported by the Consortium for Advanced Simulation of Light Water Reactors (http://www.casl.gov), an Energy Innovation Hub (http://www.energy.gov/hubs) for Modeling and Simulation of Nuclear Reactors under U.S. Department of Energy Contract No. DE-AC05-00OR22725. The discharge rod internal pressure (RIP) and cladding hoop stress (CHS) distributions are quantified for Watts Bar Nuclear Unit 1 (WBN1) fuel rods by modeling core cycle design data, operation data (including modeling significant trips and downpowers), and as-built fuel enrichments and densities of each fuel rod in FRAPCON-3.5. A methodology is developed which tracks inter-cycle assembly movements and assembly batch fabrication information to build individual FRAPCON inputs for each evaluated WBN1 fuel rod. An alternate model for the amount of helium released from the zirconium diboride (ZrB2) integral fuel burnable absorber (IFBA) layer is derived and applied to FRAPCON output data to quantify the RIP and CHS for these types of fuel rods. SCALE/Polaris is used to quantify fuel rodspecific spectral quantities and the amount of gaseous fission products produced in the fuel for use in FRAPCON inputs. Fuel rods with ZrB2 IFBA layers (i.e., IFBA rods) are determined to have RIP predictions that are elevated when compared to fuel rod without IFBA layers (i.e., standard rods) despite the fact that IFBA rods often have reduced fill pressures and annular fuel pellets. The primary contributor to elevated RIP predictions at burnups less than and greater than 30 GWd

    2015-03-01

    Stigma is a widely used concept in social science research and an extensive literature claims that stigmatisation contributes to numerous negative health outcomes. However, few studies compare groups that vary in the extent to which they are stigmatised and even fewer studies examine stigma's independent and mediating effects. This article addresses these gaps in a comparative study of perceived stigma and drug use among three low-income feminised service occupations: sex work, food and alcoholic beverage serving, and barbering and hairstyling. An analysis of longitudinal data shows positive associations between sex work, perceived stigma, and socially less acceptable drug use (for example, heroin and cocaine), and that stigma mediates part of the link between sex work and the use of these drugs. Our overall findings suggest that perceived stigma is pronounced among those who work in the sex industry and negatively affects health independently of sex work involvement. © 2015 Foundation for the Sociology of Health & Illness.

    The aim of this review was to assess the clinical relevance of the relative antidepressant efficacy of escitalopram and citalopram by meta-analysis. Studies in major depressive disorder (MDD) with both escitalopram and citalopram treatment arms were identified. Adult patients had to meet DSM-IV criteria for MDD. The primary outcome measure was the treatment difference in Montgomery-Asberg Depression Rating Scale (MADRS) total score at week 8 (or last assessment if escitalopram, n=995; citalopram, n=1014). Escitalopram was significantly more effective than citalopram in overall treatment effect, with an estimated mean treatment difference of 1.7 points at week 8 (or last assessment if escitalopram. In this meta-analysis, the statistically significant superior efficacy of escitalopram compared to citalopram was shown to be clinically relevant.

    The current growth of data and information occurs rapidly in varying amount and media. These types of development will eventually produce large number of data better known as the Big Data. Business Intelligence (BI) utilizes large number of data and information for analysis so that one can obtain important information. This type of information can be used to support decision-making process. In practice a process integrating existing data and information into data warehouse is needed. This data integration process is known as Extract, Transformation and Loading (ETL). In practice, many applications have been developed to carry out the ETL process, but selection which applications are more time, cost and power effective and efficient may become a challenge. Therefore, the objective of the study was to provide comparative analysis through comparison between the ETL process using Microsoft SQL Server Integration Service (SSIS) and one using Pentaho Data Integration (PDI).

    1995-06-01

    This paper describes a framework and a high-level language toolkit for comparative analysis of genome sequence alignment The framework integrates the information derived from multiple sequence alignment and phylogenetic tree (hypothetical tree of evolution) to derive new properties about sequences. Multiple sequence alignments are treated as an abstract data type. Abstract operations have been described to manipulate a multiple sequence alignment and to derive mutation related information from a phylogenetic tree by superimposing parsimonious analysis. The framework has been applied on protein alignments to derive constrained columns (in a multiple sequence alignment) that exhibit evolutionary pressure to preserve a common property in a column despite mutation. A Prolog toolkit based on the framework has been implemented and demonstrated on alignments containing 3000 sequences and 3904 columns.

    Full Text Available Cyclooxygenase-2 (COX-2 is the main targeted protein of non-steroidal anti-inflammatory drugs (NSAID; nevertheless, the latter substantially differ in pharmacological properties.Objective: to establish the spectrum of pharmacological actions of dexketoprofen, ketoprofen, and diclofenac, by using a chemoreactome analysis.Material and methods. A chemoinformation analysis was used to determine a list of the chemical structures closest to dexketoprofen. For each molecule, the investigators extracted the results of experimental measurements of the rheological properties of this molecule from databases and a chemoreactome analysis was carried out. The comparative chemoreactome analysis of the molecule of dexketoprofen and control molecules (ketoprofen, diclofenac could assess the biological activity of the studied molecule.Results and discussion. Unlike the molecules of comparison, dexketoprofen was found to be able to accumulate mainly in muscles, adipose tissue, and adrenal glands. The anti-inflammatory and analgesic effect of dexketoprofen can be carried out via modulation not only of the metabolism of prostaglandins, but also that of leukotrienes and encephalins, as well as via inhibition of metalloproteinases and glutamate receptors. In addition, the analysis showed a considerable difference in the interaction profiles of dexketoprofen, ketoprofen, and diclofenac with cytochrome P450 enzymes. Dexketoprofen can enhance the efficacy of anti-arrhythmic and antiadrenergic agents, whereas ketoprofen and diclofenac are able to negatively affect the metabolism of omega-3 polyunsaturated fatty acids and vitamin D.Conclusion. The chemoreactome analysis could identify the promising vasodilatory, antiplatelet, antidiabetic, and antitumor effects of dexketoprofen in addition to its main action.

    The completion of the Arabidopsis thaliana genome sequence allows a comparative analysis of transcriptional regulators across the three eukaryotic kingdoms. Arabidopsis dedicates over 5% of its genome to code for more than 1500 transcription factors, about 45% of which are from families specific to plants. Arabidopsis transcription factors that belong to families common to all eukaryotes do not share significant similarity with those of the other kingdoms beyond the conserved DNA binding domains, many of which have been arranged in combinations specific to each lineage. The genome-wide comparison reveals the evolutionary generation of diversity in the regulation of transcription.

    Isolates from two cases of acute measles, one case of acute measles encephalitis and three patients with subacute sclerosing panencephalitis were compared. This comparison was based upon the electrophoretic analysis of T 1 oligonucleotides from single-stranded, full-length RNA isolated from cytoplasmic nucleocapsids. Although all viruses have oligonucleotides in common, each isolate generated a unique pattern of oligonucleotides. However, no group of oligonucleotides was observed which would allow differentiation between viruses isolated from acute infections and those isolated from CNS diseases; indicating that probably all measles viruses differ in their nucleotide sequence, regardless of origin.

    Human racial classification has long been a problem for the discipline of anthropology, but much of the criticism of the race concept has focused on its social and political connotations. The central argument of this paper is that race is not a specifically human problem, but one that exists in evolutionary thought in general. This paper looks at various disciplinary approaches to racial or subspecies classification, extending its focus beyond the anthropological race concept by providing a comparative analysis of the use of racial classification in evolutionary biology, genetics, and anthropology.

    Digital Storytelling (DST) is a method of delivering information to the audience. It combines narrative and digital media content infused with the multimedia elements. In order for the educators (i.e the designers) to create a compelling digital story, there are sets of processes introduced by experts. Nevertheless, the experts suggest varieties of processes to guide them; of which some are redundant. The main aim of this study is to propose a single guide process for the creation of DST. A comparative analysis is employed where ten DST models from various experts are analysed. The process can also be implemented in other multimedia materials that used the concept of DST.

    2011-01-01

    The objective of this paper is to examine and compare the use of a number of policy evaluation tools, which can be used to measure the impact of transport policies and programmes as part of a strategic environmental assessment (SEA) or sustainability appraisal. The evaluation tools that were examined include cost-benefit analysis (CBA), cost-effectiveness analysis (CEA) and multi-criteria decision analysis (MCDA). It was concluded that both CEA and CBA are useful for estimating the costs and/or benefits associated with transport policies but are constrained by the difficulty in quantifying non-market impacts and monetising total costs and benefits. Furthermore, CEA is limited to identifying the most 'cost-effective policy' for achieving a single, narrowly defined objective, usually greenhouse gas (GHG) reduction and is, therefore, not suitable for evaluating policy options with ancillary costs or a variety of potential benefits. Thus, CBA or CEA evaluation should be complemented by a complete environmental and socio-economic impact assessment approach such as MCDA. This method allows for participatory analysis and qualitative assessment but is subject to caveats such as subjectivity and value-laden judgments.

We administered a survey study to participants in China, Colombia, Germany, Portugal, and USA, five countries from distinct cultural regions of the world. Participants were asked to report the likelihood of engaging in seven dishonest and illegal actions, and were asked to indicate the probability and severity of consequences for legal, friend, family, and internal sanctions. Results indicated that across countries, internal sanctions had the strongest deterrent effects on crime. The deterrent effects of legal sanctions were weaker and varied across countries. Furthermore, the deterrent effects of legal sanctions were strongest when internal sanctions were lax. Unexpectedly, social sanctions were positively related to likelihood of engaging in crime. Taken together, these results suggest that the relative strengths of legal and internal sanctions are robust across cultures and dishonest actions.

    RVIs (Reactor Vessel Internals) perform important safe-related functions such as upholding the nuclear fuel assembly as well as providing the coolant passage of the reactor core and supporting the control rod drive mechanism. Therefore, the components including RVIs have to be designed and constructed taking into account the structural integrity under various accident scenarios. The reliable seismic analysis is essentially demanded to maintain the safe-related functions of RVIs. In this study, a modal analysis was performed based on the previous researches to examine values of frequencies, mode shapes and participation factors. Subsequently, the structural integrity respecting to the earthquake was evaluated through a response spectrum analysis by using the output variables of modal analysis. In this study, the structural integrity of the assembled RVIs was carried out against the seismic event via the modal and response spectrum analyses. Even though 287MPa of the maximum stress value occurred at the connected region between UGS and CSA, which was lower than its allowable value. At present, fluid-structure interaction effects are being examined for further realistic simulation, which will be reported in the near future

    The rapidly growing area of cooperative international security calls for pervasive deployment of smart sensors that render valuable information and reduce operational costs and errors. Among the sensors used, vision sensors are by far the most versatile, tangible, and rich in the information they provide about their environment. On the flip side, they are also the most complex to analyze automatically for the extraction of high-level information. The ability to process imagery in a useful manner requires at least partial functional emulation of human capabilities of visual understanding. Of all visual cues available in image data, shape is perhaps the most important for understanding the content of an image. In this paper we present an overview of ongoing research at LANL on geometric shape analysis. The objective of our research is to develop a computational framework for multiscale characterization, analysis, and recognition of shapes. This framework will enable the development of a comprehensive and connected body of mathematical methods and algorithms, based on the topological, metrical, and morphological properties of shapes. We discuss its potential applications to automated surveillance, monitoring, container tracking and inspection, weapons dismantlement, and treaty verification. The framework will develop a geometric filtering scheme for extracting semantically salient shape features. This effort creates a paradigm for solving shape-related problems in Pattern Recognition, Computer Vision, and Image Understanding in a conceptually cohesive and algorithmically amenable manner. The research aims to develop an advanced image analysis capability at LANL for solving a wide range of problems in automated facility surveillance, nuclear materials monitoring, treaty verification, and container inspection and tracking. The research provides the scientific underpinnings that will enable us to build smart surveillance cameras, with a direct practical impact on LANL

    The unfavorable phenomena, such as flow induced vibration and aging process in reactor internals, cause degradation of structural integrity and may result in loosing some mechanical binding components which might impact other equipments and components or cause flow blockage. Since these malfunctions and potential failures change reactor noise signal, it is necessary to analyze reactor noise signal for early fault diagnosis in the point of few of safety and plant economics. The objectives of this study are to establish fault diagnostic and TS(thermal shield), and to develop a data acquisition and signal processing software system. In the first year of this study, an analysis technique for the reactor internal vibration using the reactor noise was proposed. With the technique proposed and the reactor noise signals (ex-core neutron and acceleration), the dynamic characteristics of Ulchin-1 reactor internals were obtained, and compared with those of Tricastin-1 which is the prototype of Ulchin-1. In the second year, a PC-based expert system for reactor internals fault diagnosis is developed, which included data acquisition, signal processing, feature extraction function, and represented diagnostic knowledge by the IF-THEN rule.

    Lithium-ion batteries are more suitable for the application of electric vehicle due to high energy and power density compared to other rechargeable batteries. However, the battery pack temperature has a great impact on the overall performance, cycle life, normal charging-discharging behaviour and even safety. During rapid charge transferring process, the internal temperature may exceed its allowable limit (460C). In this paper, an analysis of internal temperature during charge balancing and discharging conditions is presented. Specific interest is paid to the effects of temperature on the different rate of ambient temperature and discharging current. Matlab/Simulink Li-ion battery model and quasi-resonant converter base balancing system are used to study the temperature effect. Rising internal temperature depends on the rate of balancing current and ambient temperature found in the simulation results.

    High operational temperature and pressure in offshore pipelines may lead to unexpected lateral movements, sometimes call lateral buckling, which can have serious consequences for the integrity of the pipeline. The phenomenon of lateral buckling in offshore pipelines needs to be analysed in the design phase using FEM. The analysis should take into account many parameters, including operational temperature and pressure, fluid characteristic, seabed profile, soil parameters, coatings of the pipe, free spans etc. The buckling initiation force is sensitive to small changes of any initial geometric out-of-straightness, thus the modeling of the as-laid state of the pipeline is an important part of the design process. Recently some dedicated finite elements programs have been created making modeling of the offshore environment more convenient that has been the case with the use of general purpose finite element software. The present paper aims to compare thermal buckling analysis of sub sea pipeline performed using different finite elements tools, i.e. general purpose programs (ANSYS, ABAQUS) and dedicated software (SAGE Profile 3D) for a single pipeline resting on an the seabed. The analyses considered the pipeline resting on a flat seabed with a small levels of out-of straightness initiating the lateral buckling. The results show the quite good agreement of results of buckling in elastic range and in the conclusions next comparative analyses with sensitivity cases are recommended. (author)

    2009-01-01

    The electricity sector has entered into a phase of both challenges and opportunities. Challenges include workforce retirement, labour shortages, and increased competition from other employers to attract and retain the skilled people required to deliver on the increasing demand for electricity in Canada. The electricity sector in Canada is also moving into a new phase, whereby much of the existing infrastructure is either due for significant upgrades, or complete replacement. The increasing demand for electricity means that increased investment and capital expenditure will need to be put toward building new infrastructure altogether. The opportunities for the electricity industry will lie in its ability to effectively and efficiently react to these challenges. The purpose of this report was to provide employers and stakeholders in the sector with relevant and current trend data to help them make appropriate policy and human resource decisions. The report presented a comparative analysis of a 2004 Canadian Electricity Association employer survey with a 2008 Electricity Sector Council employer survey. The comparative analysis highlighted trends and changes that emerged between the 2004 and 2008 studies. Specific topics that were addressed included overall employment trends; employment diversity in the sector; age of non-support staff; recruitment; and retirements and pension eligibility. Recommendations were also offered. It was concluded that the electricity sector could benefit greatly from implementing on-going recruitment campaigns. refs., tabs., figs

    Breast cancer is the second most common cancer worldwide and the first among women. Invasive ductal carcinoma (IDC) and invasive lobular carcinoma (ILC) are the two major histological subtypes, and the clinical and molecular differences between them justify the search for new markers to distinguish them. As proteomic analysis allows for a powerful and analytical approach to identify potential biomarkers, we performed a comparative analysis of IDC and ILC samples by using two-dimensional electrophoresis and mass spectrometry. Twenty-three spots were identified corresponding to 10 proteins differentially expressed between the two subtypes. ACTB, ACTG, TPM3, TBA1A, TBA1B, VIME, TPIS, PDIA3, PDIA6, and VTDB were upregulated in ductal carcinoma compared to in lobular carcinoma samples. Overall, these 10 proteins have a key role in oncogenesis. Their specific functions and relevance in cancer initiation and progression are further discussed in this study. The identified peptides represent promising biomarkers for the differentiation of ductal and lobular breast cancer subtypes, and for future interventions based on tailored therapy.

    Full Text Available The logic that customer satisfaction is the starting point of marketing and business activities is based on the assumption that customer satisfaction leads to customer loyalty, keeping in mind all of the positive effects that customer loyalty has on business success of an organization. Because of this, marketing and management theory and practice dedicate particular attention to the concepts of customer satisfaction and loyalty. In this paper we will use the surveys of customers of banking services not only to show the levels of their satisfaction and loyalty, but also to make a comparative analysis of data obtained through online and offline research. This approach was made possible because the research was carried out on a sample which was divided in two groups. All of the participants answered the questions from a unique questionnaire, however, one group took the survey via the Internet (online while data from the other group of participants was collected in the field by using printed questionnaires (offline. The findings of the comparative analysis of online and offline survey results are presented in the final part of the paper.

  17. Comparative evaluation of civil liability conventions on radioactive and oil pollution and liability under international law

    1988-01-01

    In the event of transfrontier radioactive pollution or oil pollution, compensation for damage may be sought under two different liability systems: there is the framework of international law of liability of international persons, and there is the liability regime established by international conventions. The latter system has adopted a very friendly attitude towards the claims of a private victim claiming compensation from the private polluter. The book first sets out the basic principles and practice of the two liability systems, also considering the latest developments and current discussions advocating the acknowledgement of the principle of strict and absolute liability in international law. The relationship of the two systems is the major issue of the book, and the Chernobyl reactor accident has made it a particularly topical issue at that. The problems arising in the wake of this accident have shown the need for clarification in this field. The author suggests as a practical approach a strict separation of the two bases of claims, so that parallel or successive procedure on the level of international law or civil law is possible. Finally the problem of avoiding duplication in the payment of compensation is discussed. (orig./HP) [de

  18. Efficiency analysis of energy networks: An international survey of regulators

    2009-01-01

    Incentive regulation for networks has been an important part of the reform agenda in a number of countries. As part of this regulatory process, incentives are put in place to improve the cost efficiency of network companies by rewarding good performance relative to a pre-defined benchmark. The techniques used to establish benchmarks are central to the efficiency improvements that are ultimately achieved. Much experience has been gained internationally in the application of benchmarking techniques and we now have a solid understanding of the main indicators of best practice. What we are lacking is a more complete understanding of the factors that influence choice of methods by regulators. In this paper, we present the results of an international survey of energy regulators in 40 countries conducted electronically between June and October 2008. Regulators from European, Australasian and Latin American countries are represented in the survey. Our results show that benchmarking techniques are now widespread in the regulation of gas and electricity networks. Best practice, however, is limited to a small number of regulators. We conclude by summarising existing trends and offering some recommendations on overcoming barriers to best practice efficiency analysis.

    The genus Mycobacterium represents more than 120 species including important pathogens of human and cause major public health problems and illnesses. Further, with more than 100 genome sequences from this genus, comparative genome analysis can provide new insights for better understanding the evolutionary events of these species and improving drugs, vaccines, and diagnostics tools for controlling Mycobacterial diseases. In this present study we aim to outline a comparative genome analysis of fourteen Mycobacterial genomes: M. avium subsp. paratuberculosis K—10, M. bovis AF2122/97, M. bovis BCG str. Pasteur 1173P2, M. leprae Br4923, M. marinum M, M. sp. KMS, M. sp. MCS, M. tuberculosis CDC1551, M. tuberculosis F11, M. tuberculosis H37Ra, M. tuberculosis H37Rv, M. tuberculosis KZN 1435 , M. ulcerans Agy99,and M. vanbaalenii PYR—1, For this purpose a comparison has been done based on their length of genomes, GC content, number of genes in different data bases (Genbank, Refseq, and Prodigal). The BLAST matrix of these genomes has been figured to give a lot of information about the similarity between species in a simple scheme. As a result of multiple genome analysis, the pan and core genome have been defined for twelve Mycobacterial species. We have also introduced the genome atlas of the reference strain M. tuberculosis H37Rv which can give a good overview of this genome. And for examining the phylogenetic relationships among these bacteria, a phylogenic tree has been constructed from 16S rRNA gene for tuberculosis and non tuberculosis Mycobacteria to understand the evolutionary events of these species.

  20. PHARMACOPOEIA METHODS FOR ELEMENTAL ANALYSIS OF MEDICINES: A COMPARATIVE STUDY

    2018-01-01

    Full Text Available The article is devoted to the problem of quality assurance of medicinal products, namely the determination of elemental impurity concentration compared to permitted daily exposures for and the correct choice analytical methods that are adequate to the formulated tasks. The paper goal is to compare characteristics of four analytical methods recommended by the Pharmacopoeia of various countries to control the content of elemental impurities in medicines, including medicinal plant raw materials and herbal medicines. Both advantages and disadvantages were described for atomic absorption spectroscopy with various atomising techniques, as well as atomic emission spectroscopy and mass spectrometry with inductively coupled plasma. The choice of the most rational analysis method depends on a research task and is reasoned from the viewpoint of analytical objectives, possible complications, performance attributes, and economic considerations. The methods of ICP-MS and GFAAS were shown to provide the greatest potential for determining the low and ultra-low concentrations of chemical elements in medicinal plants and herbal medicinal products. The other two methods, FAAS and ICP-AES, are limited to the analysis of the main essential elements and the largest impurities. The ICP-MS is the most efficient method for determining ultra-low concentrations. However, the interference of mass peaks is typical for ICP-MS. It is formed not only by impurities but also by polyatomic ions with the participation of argon, as well as atoms of gases from the air (C, N and O or matrices (O, N, H, P, S and Cl. Therefore, a correct sample preparation, which guarantees minimisation of impurity contamination and loss of analytes becomes the most crucial stage of analytical applications of ICP-MS. The detections limits for some chemical elements, which content is regulated in modern Pharmacopoeia, were estimated for each method and analysis conditions of medicinal plant raw

  1. In silico comparative genomic analysis of GABAA receptor transcriptional regulation

    2007-06-01

    Full Text Available Abstract Background Subtypes of the GABAA receptor subunit exhibit diverse temporal and spatial expression patterns. In silico comparative analysis was used to predict transcriptional regulatory features in individual mammalian GABAA receptor subunit genes, and to identify potential transcriptional regulatory components involved in the coordinate regulation of the GABAA receptor gene clusters. Results Previously unreported putative promoters were identified for the β2, γ1, γ3, ε, θ and π subunit genes. Putative core elements and proximal transcriptional factors were identified within these predicted promoters, and within the experimentally determined promoters of other subunit genes. Conserved intergenic regions of sequence in the mammalian GABAA receptor gene cluster comprising the α1, β2, γ2 and α6 subunits were identified as potential long range transcriptional regulatory components involved in the coordinate regulation of these genes. A region of predicted DNase I hypersensitive sites within the cluster may contain transcriptional regulatory features coordinating gene expression. A novel model is proposed for the coordinate control of the gene cluster and parallel expression of the α1 and β2 subunits, based upon the selective action of putative Scaffold/Matrix Attachment Regions (S/MARs. Conclusion The putative regulatory features identified by genomic analysis of GABAA receptor genes were substantiated by cross-species comparative analysis and now require experimental verification. The proposed model for the coordinate regulation of genes in the cluster accounts for the head-to-head orientation and parallel expression of the α1 and β2 subunit genes, and for the disruption of transcription caused by insertion of a neomycin gene in the close vicinity of the α6 gene, which is proximal to a putative critical S/MAR.

    Prophages have been considered genetic units that have an intimate association with novel phenotypic properties of bacterial hosts, such as pathogenicity and genomic variation. Little is known about the genetic information of prophages in the genome of Streptococcus mutans, a major pathogen of human dental caries. In this study, we identified 35 prophage-like elements in S. mutans genomes and performed a comparative genomic analysis. Comparative genomic and phylogenetic analyses of prophage sequences revealed that the prophages could be classified into three main large clusters: Cluster A, Cluster B, and Cluster C. The S. mutans prophages in each cluster were compared. The genomic sequences of phismuN66-1, phismuNLML9-1, and phismu24-1 all shared similarities with the previously reported S. mutans phages M102, M102AD, and ϕAPCM01. The genomes were organized into seven major gene clusters according to the putative functions of the predicted open reading frames: packaging and structural modules, integrase, host lysis modules, DNA replication/recombination modules, transcriptional regulatory modules, other protein modules, and hypothetical protein modules. Moreover, an integrase gene was only identified in phismuNLML9-1 prophages. PMID:29158986

  3. Comparative Analysis for Robust Penalized Spline Smoothing Methods

    2014-01-01

    Full Text Available Smoothing noisy data is commonly encountered in engineering domain, and currently robust penalized regression spline models are perceived to be the most promising methods for coping with this issue, due to their flexibilities in capturing the nonlinear trends in the data and effectively alleviating the disturbance from the outliers. Against such a background, this paper conducts a thoroughly comparative analysis of two popular robust smoothing techniques, the M-type estimator and S-estimation for penalized regression splines, both of which are reelaborated starting from their origins, with their derivation process reformulated and the corresponding algorithms reorganized under a unified framework. Performances of these two estimators are thoroughly evaluated from the aspects of fitting accuracy, robustness, and execution time upon the MATLAB platform. Elaborately comparative experiments demonstrate that robust penalized spline smoothing methods possess the capability of resistance to the noise effect compared with the nonrobust penalized LS spline regression method. Furthermore, the M-estimator exerts stable performance only for the observations with moderate perturbation error, whereas the S-estimator behaves fairly well even for heavily contaminated observations, but consuming more execution time. These findings can be served as guidance to the selection of appropriate approach for smoothing the noisy data.

    Full Text Available Traditional biomechanical analyses of human movement are generally derived from linear mathematics. While these methods can be useful in many situations, they do not describe behaviors in human systems that are predominately nonlinear. For this reason, nonlinear analysis methods based on a dynamical systems approach have become more prevalent in recent literature. These analysis techniques have provided new insights into how systems (1 maintain pattern stability, (2 transition into new states, and (3 are governed by short- and long-term (fractal correlational processes at different spatio-temporal scales. These different aspects of system dynamics are typically investigated using concepts related to variability, stability, complexity, and adaptability. The purpose of this paper is to compare and contrast these different concepts and demonstrate that, although related, these terms represent fundamentally different aspects of system dynamics. In particular, we argue that variability should not uniformly be equated with stability or complexity of movement. In addition, current dynamic stability measures based on nonlinear analysis methods (such as the finite maximal Lyapunov exponent can reveal local instabilities in movement dynamics, but the degree to which these local instabilities relate to global postural and gait stability and the ability to resist external perturbations remains to be explored. Finally, systematic studies are needed to relate observed reductions in complexity with aging and disease to the adaptive capabilities of the movement system and how complexity changes as a function of different task constraints.

    In randomized-controlled trials, interim analyses are often planned for possible early trial termination to claim superiority or futility of a new therapy. While unblinding is necessary to conduct the formal interim analysis in blinded studies, blinded data also have information about the potential treatment difference between the groups. We developed a blinded data monitoring tool that enables investigators to predict whether they observe such an unblinded interim analysis results that supports early termination of the trial. Investigators may skip some of the planned interim analyses if an early termination is unlikely. We specifically focused on blinded, randomized-controlled studies to compare binary endpoints of a new treatment with a control. Assuming one interim analysis is planned for early termination for superiority or futility, we conducted extensive simulation studies to assess the impact of the implementation of our tool on the size, power, expected number of interim analyses, and bias in the treatment effect. The numerical study showed the proposed monitoring tool does not affect size or power, but dramatically reduces the expected number of interim analyses when the effect of the treatment difference is small. The tool serves as a useful reference when interpreting the summary of the blinded data throughout the course of the trial, without losing integrity of the study. This tool could potentially save the study resources and budget by avoiding unnecessary interim analyses.

  7. How Do the Approaches to Accountability Compare for Charities Working in International Development?

    2014-01-01

    Approaches to accountability vary between charities working to reduce under-five mortality in underdeveloped countries, and healthcare workers and facilities in Canada. Comparison reveals key differences, similarities and trade-offs. For example, while health professionals are governed by legislation and healthcare facilities have a de facto obligation to be accredited, charities and other international organizations are not subject to mandatory international laws or guidelines or to de facto international standards. Charities have policy goals similar to those found in the Canadian substudies, including access, quality, cost control, cost-effectiveness and customer satisfaction. However, the relative absence of external policy tools means that these goals may not be realized. Accountability can be beneficial, but too much or the wrong kind of accountability can divert resources and diminish returns. PMID:25305397

    The analysis for immobilized Pu follows the disposal criticality analysis methodology. In this study the focus is on determining the range of chemical compositions of the configurations which can occur following the aqueous degradation processes, particularly with respect to the concentrations of uranium, plutonium, and the principal neutron absorber, gadolinium. The principal analysis tool is a mass balance program that computes the amounts of plutonium, uranium, gadolinium, and chromium in solution as a function of time with inputs from a range of possible waste form dissolution rates, stainless steel corrosion rates, and compound solubilities for the neutronically significant elements. For the waste forms and degradation modes considered here, it is possible to preclude the possibility of criticality by maintaining a plutonium loading limit. Since the presence of hafnium is shown to increase this loading limit, the defense-in-depth policy would suggest the maximization of the amount of Hf as a backup criticality control material. At the end of 1997, after this study was completed, the ceramic waste form was downselected and a new formulation was developed, with the amount of Hf increased to the point where internal criticality may no longer be possible. In addition, recent calculations indicate that GdPO 4 is insoluble over a much broader range of pH than is Gd 2 O 3 , so that its use as the Gd carrier in the waste form would provide an extra margin of defense-in-depth

For radiative heat losses it is shown that for the temperatures considered here, surface to ambient radiation is a good approximation of the heat loss. For conductive heat transfer the module efficiency is shown to be comparable to the case...... of radiative losses. Finally, heat losses due to internal natural convection in the module is shown to be negligible for the millimetre sized modules considered here. The combined case of radiative and conductive heat transfer resulted in the lowest efficiency. The optimized load resistance is found...... to decrease for increased heat loss. The leg dimensions are varied for all heat losses cases and it is shown that the ideal way to construct a TEG module with minimal heat losses and maximum efficiency is to either use a good insulating material between the legs or evacuate the module completely, and use...

    Full Text Available Sovereign funds are an important actor occurring on international financial markets in the last decade, being, in fact, state controlled international investments. Generally, they are financed from foreign currency reserves of the emergent countries they are constituted in, being managed apart of the official reserves and used for external expansion; they are likely to be detrimental to certain strategic interests. As public financial vehicles, they own, endorse or manage public funds of some emergent countries, freely invested by them in a great number of assets, being seen as a foreign policy element.

  12. Social costs of road crashes: An international analysis.

    2016-09-01

    This paper provides an international overview of the most recent estimates of the social costs of road crashes: total costs, value per casualty and breakdown in cost components. The analysis is based on publications about the national costs of road crashes of 17 countries, of which ten high income countries (HICs) and seven low and middle income countries (LMICs). Costs are expressed as a proportion of the gross domestic product (GDP). Differences between countries are described and explained. These are partly a consequence of differences in the road safety level, but there are also methodological explanations. Countries may or may not correct for underreporting of road crashes, they may or may not use the internationally recommended willingness to pay (WTP)-method for estimating human costs, and there are methodological differences regarding the calculation of some other cost components. The analysis shows that the social costs of road crashes in HICs range from 0.5% to 6.0% of the GDP with an average of 2.7%. Excluding countries that do not use a WTP- method for estimating human costs and countries that do not correct for underreporting, results in average costs of 3.3% of GDP. For LMICs that do correct for underreporting the share in GDP ranges from 1.1% to 2.9%. However, none of the LMICs included has performed a WTP study of the human costs. A major part of the costs is related to injuries: an average share of 50% for both HICs and LMICs. The average share of fatalities in the costs is 23% and 30% respectively. Prevention of injuries is thus important to bring down the socio-economic burden of road crashes. The paper shows that there are methodological differences between countries regarding cost components that are taken into account and regarding the methods used to estimate specific cost components. In order to be able to make sound comparisons of the costs of road crashes across countries, (further) harmonization of cost studies is recommended. This can be

    The group of Mycobacteria is one of the most intensively studied bacterial taxa, as they cause the two historical and worldwide known diseases: leprosy and tuberculosis. Mycobacteria not identified as tuberculosis or leprosy complex, have been referred to by ‘environmental mycobacteria’ or ‘Nontuberculous mycobacteria (NTM). Mycobacterium kansasii (M. kansasii) is one of the most frequent NTM pathogens, as it causes pulmonary disease in immuno-competent patients and pulmonary, and disseminated disease in patients with various immuno-deficiencies. There have been five documented subtypes of this bacterium, by different molecular typing methods, showing that type I causes tuberculosis-like disease in healthy individuals, and type II in immune-compromised individuals. The remaining types are said to be environmental, thereby, not causing any diseases. The aim of this project was to conduct a comparative genomic study of M. kansasii types I-V and investigating the gene expression level of those types. From various comparative genomics analysis, provided genomics evidence on why M. kansasii type I is considered pathogenic, by focusing on three key elements that are involved in virulence of Mycobacteria: ESX secretion system, Phospholipase c (plcb) and Mammalian cell entry (Mce) operons. The results showed the lack of the espA operon in types II-V, which renders the ESX- 1 operon dysfunctional, as espA is one of the key factors that control this secretion system. However, gene expression analysis showed this operon to be deleted in types II, III and IV. Furthermore, plcB was found to be truncated in types III and IV. Analysis of Mce operons (1-4) show that mce-1 operon is duplicated, mce-2 is absent and mce-3 and mce-4 is present in one copy in M. kansasii types I-V. Gene expression profiles of type I-IV, showed that the secreted proteins of ESX-1 were slightly upregulated in types II-IV when compared to type I and the secreted forms of ESX-5 were highly down

    The Clinch River Breeder Reactor Plant (CRBRP) sodium pumps are currently being designed and the prototype unit is being fabricated. In the design of these large-scale pumps for elevated temperature Liquid Metal Fast Breeder Reactor (LMFBR) service, one major design consideration is the response of the critical parts to severe thermal transients. A detailed internal fluid flow distribution analysis has been performed using a computer code HAFMAT, which solves a network of fluid flow paths. The results of the analytical approach are then compared to the test data obtained on a half-scale pump model which was tested in water. The details are presented of pump internal hydraulic analysis, and test and evaluation of the half-scale model test results

    To compare three continuous glucose monitoring (CGM) devices in subjects with type 1 diabetes under closed-loop blood glucose (BG) control. Six subjects with type 1 diabetes (age 52 ± 14 years, diabetes duration 32 ± 14 years) each participated in two 51-h closed-loop BG control experiments in the hospital. Venous plasma glucose (PG) measurements (GlucoScout, International Biomedical) obtained every 15 min (2,360 values) were paired in time with corresponding CGM glucose (CGMG) measurements obtained from three CGM devices, the Navigator (Abbott Diabetes Care), the Seven Plus (DexCom), and the Guardian (Medtronic), worn simultaneously by each subject. Errors in paired PG-CGMG measurements and data reporting percentages were obtained for each CGM device. The Navigator had the best overall accuracy, with an aggregate mean absolute relative difference (MARD) of all paired points of 11.8 ± 11.1% and an average MARD across all 12 experiments of 11.8 ± 3.8%. The Seven Plus and Guardian produced aggregate MARDs of all paired points of 16.5 ± 17.8% and 20.3 ± 18.0%, respectively, and average MARDs across all 12 experiments of 16.5 ± 6.7% and 20.2 ± 6.8%, respectively. Data reporting percentages, a measure of reliability, were 76% for the Seven Plus and nearly 100% for the Navigator and Guardian. A comprehensive head-to-head-to-head comparison of three CGM devices for BG values from 36 to 563 mg/dL revealed marked differences in performance characteristics that include accuracy, precision, and reliability. The Navigator outperformed the other two in these areas.

    Microbe-mineral and -metal interactions represent a major intersection between the biosphere and geosphere but require high-resolution imaging and analytical tools for investigating microscale associations. Electron microscopy has been used extensively for geomicrobial investigations and although used bona fide, the traditional methods of sample preparation do not preserve the native morphology of microbiological components, especially extracellular polymers. Herein, we present a direct comparative analysis of microbial interactions using conventional electron microscopy approaches of imaging at room temperature and a suite of cryogenic electron microscopy methods providing imaging in the close-to-natural hydrated state. In situ, we observed an irreversible transformation of the hydrated bacterial extracellular polymers during the traditional dehydration-based sample preparation that resulted in their collapse into filamentous structures. Dehydration-induced polymer collapse can lead to inaccurate spatial relationships and hence could subsequently affect conclusions regarding nature of interactions between microbial extracellular polymers and their environment.

    Negri, L.; Florio, L. (Rome Univ. La Sapienza (Italy). Facolta' di Ingegneria, Dipt. di Idraulica, Trasporti e Strade)

    The evaluation, choice and design of public transportation systems for urban areas requires, in addition to consolidated use parameters, other dimensions essential to supply-demand qualiflcative realignment, e.g.: 'door-to-door time' which allows system differentiation in terms of commercial velocity, frequency and length of route; technical productivity expressed as 'transport power' and 'specific transport power'; and 'system/service quality'. By the means of surveys, these factors can be incorporated into suitable mathematical models representing, in a complete and reliable way, all the functions which a given system actually delivers and those functions which it is expected to deliver by its users. This paper illustrates the application of these concepts in a comparative analysis of different public transportation options - light rail rapid transit, tram and bus networks.

    Vermiculites are clay minerals similar to montmorillonites differing for crystalline structures. The product exfoliated is odorless, hydrophobic, not irritate the skin and not the lungs. These properties provide the modified thermally vermiculite a product of broad application in the sectors of construction, agriculture and industry. The aim this work is the comparative analysis between two vermiculites micron fractions from different localities of the northeastern Brazilian region, UBM/PB and EUCATEX/PI. Samples exfoliated to 950 deg C were leached for removal of organic matter by oxidation with hydrogen peroxide. The spectroscopy in the infrared, FTIR and X-ray diffraction, XRD, were used to characterize the samples. Data from X-ray diffraction showed that the structural characteristics of the mineral samples were not significantly altered with the process of leaching and the IR spectra proved the efficiency of procedure for removal of organic impurities (author)

    1978-01-01

    A critical survey was conducted of the most relevant correlations of boiling heat transfer in forced convection flow. Most of the investigations carried out on partial nucleate boiling and fully developed nucleate boiling have led to the formulation of correlations that are not able to cover a wide range of operating conditions, due to the empirical approach of the problem. A comparative analysis is therefore required in order to delineate the relative accuracy of the proposed correlations, on the basis of the experimental data presently available. The survey performed allows the evaluation of the accuracy of the different calculating procedure; the results obtained, moreover, indicate the most reliable heat transfer correlations for the different operating conditions investigated. This survey was developed for five pressure range (up to 180bar) and for both saturation and subcooled boiling condition

    2011-03-14

    Fungi of the phylum Basidiomycota, make up some 37percent of the described fungi, and are important from the perspectives of forestry, agriculture, medicine, and bioenergy. This diverse phylum includes the mushrooms, wood rots, plant pathogenic rusts and smuts, and some human pathogens. To better understand these important fungi, we have undertaken a comparative genomic analysis of the Basidiomycetes with available sequenced genomes. We report a phylogeny that sheds light on previously unclear evolutionary relationships among the Basidiomycetes. We also define a `core proteome? based on protein families conserved in all Basidiomycetes. We identify key expansions and contractions in protein families that may be responsible for the degradation of plant biomass such as cellulose, hemicellulose, and lignin. Finally, we speculate as to the genomic changes that drove such expansions and contractions.

    Full Text Available In this paper we study a comparative analysis of VAT in different states of the world. I made some observation on this theme because I believe that VAT is very important in carrying out transactions and the increase or decrease of this tax has a major impact upon national economies and also on the quality of life in developing countries. The papers has to pourpose to make a comparison between the American and European system of taxation with its advantages and disadvantages and, in the end to render an economic model and its statistics components. VAT is a value added tax which appeared about 50 years, initially with two purposes: one to replace certain indirect taxes, and another to reduce the budget deficit according to the faith of that time. The first country that has adopted this model was France, calling it today as value-added tax.

    Objective: To explore the better diagnostic method for acute splenic artery injury through comparative analysis of CT and DSA. Methods: Fifty-seven patients with acute splenic injury were examined by CT and DSA, treated with splenic arterial embolization and then undertook follow up. Results: CT examination possessed higher sensitivity and accuracy than DSA in demonstrating splenic parenchymal laceration, intrasplenic hematoma, subcapsular hematoma, rupture of splenic capsule and combined injury of intra-abdominal organs, especially in localizing splenic laceration. And there was a high significant difference statistically between the two kinds of examination (χ 2 =10.71, P 2 =12.57, P<0.005). Conclusions: CT and DSA are complementary in the diagnosis of splenic injury. After CT confirmation of splenic injury and the patient vital signs being stable, DSA should be referred to as soon as possible for further detail information as well as for possible interventional embolization and reduction of surgical complications.

    Ried, W

    1998-08-01

    The paper applies the method of comparative dynamic analysis to the full Grossman model. For a particular class of solutions, it derives the equations implicitly defining the complete trajectories of the endogenous variables. Relying on the concept of Frisch decision functions, the impact of any parametric change on an endogenous variable can be decomposed into a direct and an indirect effect. The focus of the paper is on marginal changes in the rate of health capital depreciation. It also analyses the impact of either initial financial wealth or the initial stock of health capital. While the direction of most effects remains ambiguous in the full model, the assumption of a zero consumption benefit of health is sufficient to obtain a definite for any direct or indirect effect.

    Looking at present day electricity scenario, there is a major electricity crisis in rural areas. The farmers are still dependant on the monsoon rains for their irrigation needs and livestock maintenance. Some of the agrarian population has opted to use Diesel Generators for pumping water in their fields. But taking into consideration the economics and environmental conditions, the above choice is not suitable for longer run. An effort to shift from non-renewable sources such as diesel to renewable energy source such as solar has been highlighted. An approximate comparative analysis showing the life cycle costs of a PV pumping system with Diesel Generator powered water pumping is done using MATLAB/STMULTNK.

    Full Text Available Data mining involves the computational process to find patterns from large data sets. Classification, one of the main domains of data mining, involves known structure generalizing to apply to a new dataset and predict its class. There are various classification algorithms being used to classify various data sets. They are based on different methods such as probability, decision tree, neural network, nearest neighbor, boolean and fuzzy logic, kernel-based etc. In this paper, we apply three diverse classification algorithms on ten datasets. The datasets have been selected based on their size and/or number and nature of attributes. Results have been discussed using some performance evaluation measures like precision, accuracy, F-measure, Kappa statistics, mean absolute error, relative absolute error, ROC Area etc. Comparative analysis has been carried out using the performance evaluation measures of accuracy, precision, and F-measure. We specify features and limitations of the classification algorithms for the diverse nature datasets.

    2009-03-01

    Full Text Available Abstract Background Spontaneous tumors in dog have been demonstrated to share many features with their human counterparts, including relevant molecular targets, histological appearance, genetics, biological behavior and response to conventional treatments. Mammary tumors in dog therefore provide an attractive alternative to more classical mouse models, such as transgenics or xenografts, where the tumour is artificially induced. To assess the extent to which dog tumors represent clinically significant human phenotypes, we performed the first genome-wide comparative analysis of transcriptional changes occurring in mammary tumors of the two species, with particular focus on the molecular pathways involved. Results We analyzed human and dog gene expression data derived from both tumor and normal mammary samples. By analyzing the expression levels of about ten thousand dog/human orthologous genes we observed a significant overlap of genes deregulated in the mammary tumor samples, as compared to their normal counterparts. Pathway analysis of gene expression data revealed a great degree of similarity in the perturbation of many cancer-related pathways, including the 'PI3K/AKT', 'KRAS', 'PTEN', 'WNT-beta catenin' and 'MAPK cascade'. Moreover, we show that the transcriptional relationships between different gene signatures observed in human breast cancer are largely maintained in the canine model, suggesting a close interspecies similarity in the network of cancer signalling circuitries. Conclusion Our data confirm and further strengthen the value of the canine mammary cancer model and open up new perspectives for the evaluation of novel cancer therapeutics and the development of prognostic and diagnostic biomarkers to be used in clinical studies.

  18. Comparative analysis of linear motor geometries for Stirling coolers

    Science.gov (United States)

    R, Rajesh V.; Kuzhiveli, Biju T.

    2017-12-01

    Compared to rotary motor driven Stirling coolers, linear motor coolers are characterized by small volume and long life, making them more suitable for space and military applications. The motor design and operational characteristics have a direct effect on the operation of the cooler. In this perspective, ample scope exists in understanding the behavioural description of linear motor systems. In the present work, the authors compare and analyze different moving magnet linear motor geometries to finalize the most favourable one for Stirling coolers. The required axial force in the linear motors is generated by the interaction of magnetic fields of a current carrying coil and that of a permanent magnet. The compact size, commercial availability of permanent magnets and low weight requirement of the system are quite a few constraints for the design. The finite element analysis performed using Maxwell software serves as the basic tool to analyze the magnet movement, flux distribution in the air gap and the magnetic saturation levels on the core. A number of material combinations are investigated for core before finalizing the design. The effect of varying the core geometry on the flux produced in the air gap is also analyzed. The electromagnetic analysis of the motor indicates that the permanent magnet height ought to be taken in such a way that it is under the influence of electromagnetic field of current carrying coil as well as the outer core in the balanced position. This is necessary so that sufficient amount of thrust force is developed by efficient utilisation of the air gap flux density. Also, the outer core ends need to be designed to facilitate enough room for the magnet movement under the operating conditions.

    2014-08-01

    Full Text Available INTRODUCTION: The economic and social development of Brazil during the recent decades has contributed to the installation of several new undergraduate and graduate study programs, as is the case of the undergraduate biochemistry programs at UFV, UFSJ and UEM. The new biochemical professionals are being prepared to work mainly in Industries, research Institutes, government agencies and Universities in all fields that involve Biochemistry and Molecular Biology. The aim of this study was to conduct a comparative analysis of the courses in Biochemistry in Brazil. MATERIAL AND METHODS: Comparative analysis of the course units of the UFV, UFSJ and UEM programs, centered on the curricula contents and organization and on the profiles of the students in terms of parameters such as the number of admissions and the graduation completion rates. RESULTS AND DISCUSSION: The UFV and UEM programs present a very similar distribution of workload over the biological, exact sciences, humanities, biochemical specialties and technological applications. The UFSJ program presents higher workloads in the areas of biological sciences and technological applications. No significant differences in the distribution of the workloads of mandatory and optional disciplines, complementary activities and supervised activities were detected. Over the past five years there was a decrease in the number of students that abandoned the programs, despite the increased retention time in the three courses. Most graduated students at both UFV and UFSJ continue their academic career toward the Master or Doctor degrees. CONCLUSION: Little difference between the study programs analyzed. This is somewhat surprising if one considers the fact that individual conception of each program was based on different local conditions and needs, which indeed justify small differences. The similarity of the programs, on the other hand, reflects the universality of the biochemical sciences and their broad

  20. Bisphenol A alters gut microbiome: Comparative metagenomics analysis.

    Mounting evidence has shown that an alteration of the gut microbiota is associated with diet, and plays an important role in animal health and metabolic diseases. However, little is known about the influence of environmental contaminants on the gut microbial community. Bisphenol A (BPA), which is widely used for manufacturing plastic products, has recently been classified as an environmental obesogen. Although many studies have demonstrated the metabolic-disrupting effects of BPA on liver and pancreatic functions, the possible effects of this synthetic compound on the metabolic diversity of the intestinal microbiota is unknown. Using 16S rRNA gene sequencing analysis on caecum samples of CD-1 mice, the present study aimed to test the hypothesis that dietary BPA intake may influence the gut microbiota composition and functions, an important attributing factor to development of the metabolic syndrome. A high-fat diet (HFD) and high-sucrose diet (HSD) were included as the positive controls for comparing the changes in the intestinal microbial profiles. Our results demonstrated a significant reduction of species diversity in the gut microbiota of BPA-fed mice. Alpha and beta diversity analyses showed that dietary BPA intake led to a similar gut microbial community structure as that induced by HFD and HSD in mice. In addition, comparative analysis of the microbial communities revealed that both BPA and a HFD favored the growth of Proteobacteria, a microbial marker of dysbiosis. Consistently, growth induction of the family Helicobacteraceae and reduction of the Firmicutes and Clostridia populations were observed in the mice fed BPA or a HFD. Collectively, our study highlighted that the effects of dietary BPA intake on the shift of microbial community structure were similar to those of a HFD and HSD, and revealed microbial markers for the development of diseases associated with an unstable microbiota.

    2008-07-01

    A comparative keyword analysis of the content of nine leading journals is used to suggest potential new directions for medical sociology. The major British and American journals in sociology and medical sociology tend to publish authors based in their own countries, contrasting with the internationalism of other social science disciplines relevant to health, although Sociology of Health and Illness is an exception to this. Medical sociology journals on both sides of the Atlantic focus on individual experience more than general sociology journals, which focus more on social systems levels of analysis. While journal contents reveal British medical sociology to be relatively atheoretical when compared with British general sociology journals, American medical sociology appears relatively apolitical on the same comparison with American general journals. American journals of sociology publish more quantitative studies than their British equivalents, more studies concerning race and other social divisions in American society, and less work drawing on social constructionist perspectives or that is engaged with social theory. Analysis of health and health care at societal and global levels and a deeper engagement with the political and public issues that concern non-sociologists represents a possible future for a medical sociology that is internationally relevant and outward looking.

Ltd, Zhejiang, China; 6New York State Institute for Basic Research in Developmental Disabilities, Staten Island, NY, USA Introduction: Multidrug resistance in Streptococcus pneumoniae has emerged as a serious problem to public health. A further understanding of the genetic diversity in antibiotic-resistant S. pneumoniae isolates is needed. Methods: We conducted whole-genome resequencing for 25 pneumococcal strains isolated from children with different antimicrobial resistance profiles. Comparative analysis focus on detection of single-nucleotide polymorphisms (SNPs and insertions and deletions (indels was conducted. Moreover, phylogenetic analysis was applied to investigate the genetic relationship among these strains. Results: The genome size of the isolates was ~2.1 Mbp, covering >90% of the total estimated size of the reference genome. The overall G+C% content was ~39.5%, and there were 2,200–2,400 open reading frames. All isolates with different drug resistance profiles harbored many indels (range 131–171 and SNPs (range 16,103–28,128. Genetic diversity analysis showed that the variation of different genes were associated with specific antibiotic resistance. Known antibiotic resistance genes (pbps, murMN, ciaH, rplD, sulA, and dpr were identified, and new genes (regR, argH, trkH, and PTS-EII closely related with antibiotic resistance were found, although these genes were primarily annotated

    Full Text Available For the past 10 to 13 million years, Antarctic notothenioid fish have undergone extraordinary periods of evolution and have adapted to a cold and highly oxygenated Antarctic marine environment. While these species are considered an attractive model with which to study physiology and evolutionary adaptation, they are poorly characterized at the molecular level, and sequence information is lacking. The transcriptomes of the Antarctic fishes Notothenia coriiceps, Chaenocephalus aceratus, and Pleuragramma antarcticum were obtained by 454 FLX Titanium sequencing of a normalized cDNA library. More than 1,900,000 reads were assembled in a total of 71,539 contigs. Overall, 40% of the contigs were annotated based on similarity to known protein or nucleotide sequences, and more than 50% of the predicted transcripts were validated as full-length or putative full-length cDNAs. These three Antarctic fishes shared 663 genes expressed in the brain and 1,557 genes expressed in the liver. In addition, these cold-adapted fish expressed more Ub-conjugated proteins compared to temperate fish; Ub-conjugated proteins are involved in maintaining proteins in their native state in the cold and thermally stable Antarctic environments. Our transcriptome analysis of Antarctic notothenioid fish provides an archive for future studies in molecular mechanisms of fundamental genetic questions, and can be used in evolution studies comparing other fish.

    To evaluate whether MRI correlates with CT and SPECT imaging for the diagnosis of juvenile spondylolysis, and to determine whether MRI can be used as an exclusive image modality. Juveniles and young adults with a history of extension low back pain were evaluated by MRI, CT and SPECT imaging. All images were reviewed blindly. Correlative analyses included CT vs MRI for morphological grading and SPECT vs MRI for functional grading. Finally, an overall grading system compared MRI vs CT and SPECT combined. Statistical analysis was performed using the kappa statistic. Seventy-two patients (mean age 16 years) were recruited. Forty pars defects were identified in 22 patients (31%), of which 25 were chronic non-union, five acute complete defects and ten acute incomplete fractures. Kappa scores demonstrated a high level of agreement for all comparative analyses. MRI vs SPECT (kappa: 0.794), MRI vs CT (kappa: 0.829) and MRI vs CT/SPECT (kappa: 0.786). The main causes of discrepancy were between MRI and SPECT for the diagnosis of stress reaction in the absence of overt fracture, and distinguishing incomplete fractures from intact pars or complete defects. MRI can be used as an effective and reliable first-line image modality for diagnosis of juvenile spondylolysis. However, localised CT is recommended as a supplementary examination in selected cases as a baseline for assessment of healing and for evaluation of indeterminate cases. (orig.)

    N-Terminal Methionine Excision (NME) is a universally conserved mechanism with the same specificity across all life forms that removes the first Methionine in proteins when the second residue is Gly, Ala, Ser, Cys, Thr, Pro, or Val. In spite of its necessity for proper cell functioning, the functional role of NME remains unclear. In 1988, Arfin and Bradshaw connected NME with the N-end protein degradation rule and postulated that the role of NME is to expose the stabilizing residues with the goal to resist protein degradation. While this explanation (that treats 7 stabilizing residues in the same manner) has become the de facto dogma of NME, comparative proteogenomics analysis of NME tells a different story. We suggest that the primary role of NME is to expose only two (rather than seven) amino acids Ala and Ser for post-translational modifications (e.g., acetylation) rather than to regulate protein degradation. We argue that, contrary to the existing view, NME is not crucially important for proteins with 5 other stabilizing residue at the 2nd positions that are merely bystanders (their function is not affected by NME) that become exposed to NME because their sizes are comparable or smaller than the size of Ala and Ser.

  13. Textbooks in transitional countries: Towards a methodology for comparative analysis

    Full Text Available In its first part, the paper analyses the ambiguous nature of the book as a medium: its physical production and its distribution to the end user takes place on a market basis; on the other hand, its content is predominantly consumed in a sector that was at least in the continental Europe traditionally considered as public and non-profit making. This ambiguous nature of the book and with it the impact of the market on the organization of knowledge in book format remains a dark spot in contemporary book research. On the other hand, textbooks are considered as ephemera both in contemporary education and book studies. Therefore, research on textbooks publishing models could be considered as a blind-spot of contemporary social studies. As a consequence, in the majority of European countries, textbook publishing and the organization of the textbook market are considered as self-evident. Throughout a comparative analysis of textbook publishing models in small transitional and developed countries, the paper points out that this self-evident organization of the textbook market is always culturally determined. In its final part, the paper compares different models of textbook publishing and outlines the scenarios for the development of the Slovene textbook market.

    The biophysical characterization of drug binding to proteins plays a key role in structural biology and in the discovery and optimization of drug discovery processes. The search for optimal combinations of biophysical techniques that can correctly and efficiently identify and quantify binding of metal-based drugs to their final target is challenging, due to the physicochemical properties of these agents. Different cisplatin derivatives have shown different citotoxicities in most common cancer lines, suggesting that they exert their biological activity via different mechanisms of action. Here we carried out a comparative analysis, by studying the behaviours of three Pt-compounds under the same experimental conditions and binding assays to properly deepen the determinants of the different MAOs. Indeed we compared the results obtained using surface plasmon resonance, isothermal titration calorimetry, fluorescence spectroscopy and thermal shift assays based on circular dichroism experiments in the characterization of the formation of adducts obtained upon reaction of cisplatin, carboplatin and iodinated analogue of cisplatin, cis-Pt (NH 3 ) 2 I 2 , with the model protein hen egg white lysozyme, both at neutral and acid pHs. Further we reasoned on the applicability of employed techniques for the study the thermodynamics and kinetics of the reaction of a metallodrug with a protein and to reveal which information can be obtained using a combination of these analyses. Data were discussed on the light of the existing structural data collected on the platinated protein.

    Full Text Available A thermal buckling analysis of functionally graded thick rectangular plates accord¬ing to von Karman non-linear theory is presented. The material properties of the functionally graded plate, except for the Poisson’s ratio, were assumed to be graded in the thickness direction, according to a power-law distribution, in terms of the volume fractions of the metal and ceramic constituents. Formulations of equilibrium and stability equations are derived using the high order shear deformation theory based on different types of shape functions. Analytical method for determination of the critical buckling temperature for uniform increase of temperature, linear and non-linear change of temperature across thickness of a plate is developed. Numeri¬cal results were obtained in МATLAB software using combinations of symbolic and numeric values. The paper presents comparative results of critical buckling tempera¬ture for different types of shape functions. The accuracy of the formulation presented is verified by comparing to results available from the literature.

    Highlights: • New regenerative Brayton cycle has been introduced. • New cycle has higher thermal efficiency and lower exhausted heat per output power. • Regenerator may remain useful in the new cycle even at high pressure ratio. • New regenerative Brayton cycle is suggested for low pressure ratio operations. - Abstract: Gas turbines are frequently used for power generation. Brayton cycle is the basis for gas turbine operation and developing the alternative cycles. Regenerative Brayton cycle is a developed cycle for basic Brayton cycle with higher thermal efficiency at low to moderate pressure ratios. A new regenerative Brayton cycle has been introduced in the present study. Energy analysis has been conducted on ideal cycles to compare them from the first law of thermodynamics viewpoint. Comparative analyses showed that the new regenerative Brayton cycle has higher thermal efficiency than the original one at the same pressure ratio, and also lower heat absorption and exhausted heat per unite output power. Computed results show that new cycle improves thermal efficiency from 12% to 26% relative to the original regenerative Brayton cycle in the range of studied pressure ratios. Contrary to the original regenerative Brayton cycle, regenerator remains useful in the new regenerative Brayton cycle even at higher pressure ratio.

    Full Text Available The MOOC platforms have known a considerable development in recent years due to the enlargement of online space and the shifting between traditional to virtual activities. These plat-forms made it possible for people almost everywhere to take online academic courses offered by top universities via open access to web and with unlimited participation. Thus, it came naturally to us to address the question what makes them so successful? The purpose of this paper is to report comparatively MOOC platforms in terms of features, based on the user’s implication and demands. First, we chose four relevant lifelong learning platforms and then we structured three main categories for the platforms' qualification, depending on which we built our theory regarding the comparison between them. Our analysis consists of three sets of criteria: business model, course design and popularity among online users. Starting from this perspective, we built a range of representative factors for which we highlighted the major aspects for each plat-form in our comparative research

    Control systems are vital to the safe operation of nuclear reactors. Their seismic design requirements are some of the most important criteria governing reactor system design evaluation. Consequently, the seismic analysis for nuclear reactors is directed to include not only the mechanical and structural seismic capabilities of a reactor, but the control system functional requirements as well. In the study described an alternate conceptual design of a safety rod system was compared with a prototypic system design to assess their relative functional reliabilities under design seismic conditions. The comparative methods utilized standard success tree and decision tree techniques to determine the relative figures of merit. The study showed: (1) The methodology utilized can provide both qualitative and quantitative bases for design decisions regarding seismic functional capabilities of two systems under comparison, (2) the process emphasizes the visibility of particular design features that are subject to common mode failure while under seismic loading, and (3) minimal improvement was shown to be available in overall system seismic performance of an independent conceptual design, however, it also showed the system would be subject to a new set of operational uncertainties which would have to be resolved by extensive development programs

    To explore the molecular basis of Sb tolerance mechanism in plant, a comparative proteomic analysis of both roots and leaves in Miscanthus sinensis has been conducted in combination with physiological and biochemical analyses. M. sinensis seedlings were exposed to different doses of Sb, and both roots and leaves were collected after 3 days of treatment. Two-dimensional gel electrophoresis (2-DE) and image analyses found that 29 protein spots showed 1.5-fold change in abundance in leaves and 19 spots in roots, of which 31 were identified by MALDI-TOF-MS and MALDI-TOF-TOF-MS. Proteins involved in antioxidant defense and stress response generally increased their expression all over the Sb treatments. In addition, proteins relative to transcription, signal transduction, energy metabolism and cell division and cell structure showed a variable expression pattern over Sb concentrations. Overall these findings provide new insights into the probable survival mechanisms by which M. sinensis could be adapting to Sb phytotoxicity. - Highlights: • Proteomics in Miscanthus sinensis leaves and roots exposed to Sb stress were studied. • There were 31 spots that were identified by mass spectrometry. • Most of these proteins were involved in antioxidant defense and stress response. • Our findings provide new insights into the tolerant mechanisms to Sb stress. - Miscanthus sinensis proteomic analysis under Sb stress reveals probable molecular mechanisms on Sb detoxification
