    Schumacker, Randall E.

    In comparing measurement theories, it is evident that the awareness of the concept of measurement error during the time of Galileo has lead to the formulation of observed scores comprising a true score and error (classical theory), universe score and various random error components (generalizability theory), or individual latent ability and error…

  2. Contemporary prophetic preaching theory in the United States of America and South Africa: A comparative study through the lens of shared Reformation roots

    Directory of Open Access Journals (Sweden)

    Leonora Tubbs Tisdale

    2014-02-01

    Full Text Available In this article two homileticians – one from the United States of America (USA and one from South Africa (SA − enter into a dialog regarding how the task of prophetic preaching today might be revived, reframed and redefined in light of the Reformation principle of the viva vox Evangelii [living voice of the gospel]. Each author begins by summarising four contemporary approaches to prophetic preaching set forth by Reformed and Lutheran homiletical scholars in their respective contexts. Then each addresses the questions: Where do I particularly see Reformation themes and emphases at work in the work of these homileticians? And how might those Reformation emphases continue to challenge and reframe preaching practices today? Finally, each gives initial eflections on how a comparison between the perspectives deeens and expands his or her nderstanding of prophetic preaching and its role in church and society.

  3. Cohabitation in Latin America: a comparative perspective

    OpenAIRE

    2014-01-01

    The coexistence of marriage and cohabitation is an intriguing feature of Latin American nuptiality. Historically common among lower social classes in Central America and the Caribbean, the incidence of cohabitation is also increasing among higher educated groups and southern Latin American countries. This study uses census and survey data to investigate the characteristics of Latin American cohabitation.First, the countries’ socioeconomic characteristics, related to the incidence of cohabitat...

  4. Comparative study of forensic psychiatric system between China and America.

    Li, Gangqin; Gutheil, Thomas G; Hu, Zeqing

    2016-01-01

    Laws and regulations about the forensic psychiatric systems in China and America were compared, and suggestions for improving the forensic psychiatric system of China were provided. There are many differences regarding the role of the forensic psychiatrist, the initiation of the assessment and the admission of expert opinion because of elements in the legal systems in China and America. The Chinese system has the advantages of objectivity, cost saving and high efficiency; but it has deficiencies in procedural justice and the admission of expert opinion. China can persist with the current system while taking measures to give more rights to the litigants to participate in their assessment, and while improving the quality and utility of the expert opinion; however, this review article will compare broadly the two systems without addressing human rights issues or procedural justice issues, nor will it presume to address the entirety of Chinese systems. In addition, China is developing its legal system for dealing with the mentally ill defendant in situations involving the criminal justice system and civil commitment. Although China enacted new laws regarding the mandatory treatment for the mentally ill, both in criminal and civil systems, there remain many aspects to be improved, including but not limited to a system of review of the decision to detain a patient on psychiatric grounds, and the need for provisions in the laws preventing indefinite detention. From this viewpoint, America's laws and regulations are instructive for us, in matters such as the method of dealing with the mentally ill defendant who is "incompetent to stand trial", "not guilty only by reason of insanity" or "guilty but mentally ill". The conditional release of the committed mentally ill person and the special programs in the forensic security hospital are all worthy of study by China in order to manage the mentally ill offender and to reduce the recidivism rate.

  5. Traditional and modern cohabitation in Latin America: A comparative typology

    Directory of Open Access Journals (Sweden)

    Maira Covre-Sussai

    2015-05-01

    Full Text Available Background: The existence of cohabitation is a historical feature of nuptiality in Latin America. Traditionally, cohabitation was common in less developed regions, among the lower social classes. But today its occurrence is increasing and in social groups and regions in which it was not common. The features of this latter type of cohabitation remain unclear. Objective: We differentiate types of cohabitation in Latin America on the basis of relationship context at its outset and its outcomes in terms of childbearing. The comparability of these types over countries is attested, as well as their evolution over time and the educational and age profiles of cohabitants. Methods: Demographic and Health Survey data for the 1980s, 1990s, and 2000s for up to eight countries are analyzed by means of Multiple Group Latent Class Analysis. Results: Three types of cohabitation are found. The traditional type includes young and lower-educated women who start to cohabit during adolescence. They have more children at younger ages. The remaining two types of cohabitation included higher-educated women and are considered modern. The innovative type groups women from all age groups, with fewer children born at a higher age and never as a single woman. Blended cohabitation refers to older women, who could negotiate a marriage, but do not. They start to cohabit during adulthood, but always after single pregnancy. Conclusions: The persistence of historical trends is attested. Traditional cohabitation is related to socioeconomic deprivation and prevails in Central American and Caribbean countries.However, two modern types of cohabitation are emerging in the region. They are concentrated in the South and related to women's independence.

In the context of this argument we establish the importance of class analysis for grasping the changing dynamics of imperial power before proceeding to argue how specific alignments of class forces in the world economy, in their interactions with existing imperial power configurations, is leading to a realignment of economic power in the world capitalist system that constitutes a major challenge for US imperialism in its Latin American operations. In the final section of the paper we point to the discontinuities and continuities in US imperial relations with Latin America, and the potentialities and constraints of these relations on economic growth and development.Keywords: Imperialism Theory, US

    以背景依赖理论为基础,通过规范研究的方式从中美比较的独特视角,探讨中美文化与社会背景的差异及其对企业社会责任的影响。研究表明,美国个人主义价值观对个人权利的尊崇,对政府权力集中的警惕,使美国形成了“大社会———小政府”的社会结构,高度发达的非政府组织、独立自由的新闻媒体、自主维权的社会公众,这些都构成了对企业生死攸关的社会责任社会压力机制。而中国集体主义价值观对整体价值的强调,对政府干预的路径依赖,使中国形成了“强政府———弱社会”的社会结构,非政府组织的弱小幼稚、新闻媒体监督功能的不足、公众社会责任意识的淡薄,这些都导致了企业社会责任社会压力机制的缺失,加剧了企业的社会责任问题。%Based on the Context Dependency Theory, taking the normative research method, culture and social background differences between China and the United States and its impacts on corporate social responsibility is discussed from the unique perspective of the comparative analysis of China and the United States. The study shows that American individualism values ’ respect for individual rights, wary of the government ’ s power concentration, helps the United States form the social structure of a "big society and small government". Highly developed non-governmental organizations, independent and free news media, and autonomously protecting own rights on the public constitute the social pressure mechanism of the vital corporate social responsibility. China’ s collectivism values emphasize the overall value and ignores individual rights, and it makes China a " strong government and weak society". The underdevelopment of non government organization, the deficiency in the supervision function of news media, the weakness of the public social responsibility consciousness lead to the lack of social pressure

  14. Comparing operadic theories of $n$-categories

    CERN Document Server

    Cheng, Eugenia

    2008-01-01

    We give a framework for comparing on the one hand theories of n-categories that are weakly enriched operadically, and on the other hand n-categories given as algebras for a contractible globular operad. Examples of the former are the definition by Trimble and variants (Cheng-Gurski) and examples of the latter are the definition by Batanin and variants (Leinster). We will show how to take a theory of n-categories of the former kind and produce a globular operad whose algebras are the n-categories we started with. We first provide a generalisation of Trimble's original theory that allows for the use of other parametrising operads in a very general way, via the notion of categories weakly enriched in V where the weakness is parametrised by an operad P in the category V. We define weak n-categories by iterating the weak enrichment construction using a series of parametrising operads P_i. We then show how to construct from such a theory an n-dimensional globular operad for each $n \\geq 0$ whose algebras are precis...

    The production and usage amount of pesticides in US rank the leading position in the world. On the basis of protecting the environment and human health, US government has enacted a series of laws and regulations to normalize and manage the production and use of pesticides so as to ensure the development of modern agriculture. In this paper, US pesticide management system is briefly reviewed and compared with the pesticide management system of China, which may provide good reference for china in establishing its own management system and make steps towards the international standard.

  17. How theories became knowledge: Morgan's chromosome theory of heredity in America and Britain.

    Science.gov (United States)

    Brush, Stephen G

    2002-01-01

    T. H. Morgan, A. H. Sturtevant, H. J. Muller and C. B. Bridges published their comprehensive treatise The Mechanism of Mendelian Heredity in 1915. By 1920 Morgan's "Chromosome Theory of Heredity" was generally accepted by geneticists in the United States, and by British geneticists by 1925. By 1930 it had been incorporated into most general biology, botany, and zoology textbooks as established knowledge. In this paper, I examine the reasons why it was accepted as part of a series of comparative studies of theory-acceptance in the sciences. In this context it is of interest to look at the persuasiveness of confirmed novel predictions, a factor often regarded by philosophers of science as the most important way to justify a theory. Here it turns out to play a role in the decision of some geneticists to accept the theory, but is generally less important than the CTH's ability to explain Mendelian inheritance, sex-linked inheritance, non-disjunction, and the connection between linkage groups and the number of chromosome pairs; in other words, to establish a firm connection between genetics and cytology. It is remarkable that geneticists were willing to accept the CTH as applicable to all organisms at a time when it had been confirmed only for Drosophila. The construction of maps showing the location on the chromosomes of genes for specific characters was especially convincing for non-geneticists. PMID:12549500

  18. The Younger Dryas ET Impact Theory and Terminal Pleistocene Mammalian Extinctions in North America

    Science.gov (United States)

    Erlandson, J. M.; Kennett, D. J.; Kennett, J.; Braje, T.; Culleton, B.

    2007-05-01

    Despite decades of intensive study and debate, no consensus has been reached on what caused the extinction of North America's mammalian megafauna at the end of the Pleistocene. In a scholarly standoff, prominent scientists have shown that neither "human overkill" or "climate change" models adequately account for the patterns found in the paleontological and archaeological records of North America. The Younger Dryas ET Impact theory may dramatically alter this debate, adding a catastrophic trigger to help explain the rapid extinction of many large mammals about 12,900 years ago. New data suggest that an extraterrestrial impact focused in northern and eastern North America may have devastated the megafauna through: (1) direct mortality caused by the impacts shock wave, debris, and massive wildfires; (2) dramatic reduction of terrestrial food supplies, rapid climatic change, and ecological reorganization; and (3) coup-de-grace effects of surviving human populations rapidly expanding after the impact.

  19. West Nile virus and its theories, a big puzzle in Mexico and Latin America

    Directory of Open Access Journals (Sweden)

    Darwin Elizondo-Quiroga

    2013-01-01

    Full Text Available It has been 13 years since the first outbreak of West Nile Virus (WNV occurred in the Americas. Since then, thousands of human cases have been reported in the United States. In contrast, there has not yet been an outbreak of WNV in any Latin American countries, including Mexico where <20 cases have been reported. We aimed to review publications to gather the main theories related to the fact that not all the countries of the continent reported human cases or that they have reported few cases since the introduction of WNV in the Western Hemisphere. We identified relevant publications using the PubMed database. Furthermore, we present on-line published information from Mexico. We found that researchers have tried to explain this phenomenon using several theories, like pre-existing antibodies against a heterotypical virus that have conferred cross protection in the population. Another explanation is that the strains circulating in Latin America are attenuated or that they came from a different origin of introduction in the continent. Another theory is that a conclusive diagnostic in regions where more than one Flavivirus is circulating results in cross-reaction in serological tests. Probably the sum of factors described by researchers in these theories in order to explain the behavior of the virus has resulted in the low number of reported cases in Latin America.

  3. Adolescent Peer Relations and Socioemotional Development in Latin America: Translating International Theory into Local Research.

    Science.gov (United States)

    Berger, Christian; Lisboa, Carolina; Cuadros, Olga; de Tezanos-Pinto, Pablo

    2016-06-01

    Peer relations constitute a main developmental context for adolescents. Peers offer an instance for identity definition and set the norms of acceptable and valued characteristics, behaviors, and attitudes, representing a societal model that allows and restrains avenues for adolescents' socioemotional development. The present article departs from these considerations to review research on adolescents' peer relations in Latin America from a socioemotional perspective. First, approaches to adolescence are discussed, with a main focus on attachment and identity theories, based on a bioecological framework. Then, a review of research in Latin America on friendships, school climate, and intergroup relations is presented. The discussion addresses the tension between theories and evidence generated in developed societies and highlights the particularities of Latin American youth, stressing the need for collecting local data.

    2016-01-01

    We introduce a decision scheme for optimally choosing a classifier, which segments the cosmic web into different structure types (voids, sheets, filaments, and clusters). Our framework, based on information theory, accounts for the design aims of different classes of possible applications: (i) parameter inference, (ii) model selection, and (iii) prediction of new observations. As an illustration, we use cosmographic maps of web-types in the Sloan Digital Sky Survey to assess the relative performance of the classifiers T-web, DIVA and ORIGAMI for: (i) analyzing the morphology of the cosmic web, (ii) discriminating dark energy models, and (iii) predicting galaxy colors. Our study substantiates a data-supported connection between cosmic web analysis and information theory, and paves the path towards principled design of analysis procedures for the next generation of galaxy surveys. We have made the cosmic web maps, galaxy catalog, and analysis scripts used in this work publicly available.

    2013-01-01

    Full Text Available Purpose – The purpose of this study is to examine the diffusion pattern of new products in Latin America, and to compare the results of principal component analysis with other descriptive approaches. Design/methodology/approach – The author studies the introduction of eight new products in nine Latin American countries, analysing their diffusion rate, market potential, adoption and take-off. He performs a principal component analysis and presents a biplot. The results obtained are compared using the Mantel test. Findings – The results indicate that the approaches used are complementary. The biplot describes 92 per cent of the explained variance. Except for a few cases, in general, the diffusion pattern in Latin America is mainly determined by cross-country wealth differences. Research limitations/implications – This study only analyses durable goods, and does not include any Central American country. Practical implications – This study helps companies to predict which will be the characteristics of the diffusion pattern of other new products and to forecast their future sales. Social implications – This study helps public actors to decide how to segment the Latin American market when implementing policies that encourage the diffusion of new products. Originality/value – This research extends our current knowledge on the diffusion of innovations in emerging and less developed countries. This is the first study to compare the characteristics of innovation diffusion patterns in Latin America.

    2007-01-01

    The challenge of making central requirements work at local levels is a common problem for environmental governance throughout the world.Countries can learn from one another's approaches,but must understand the local con text in which they are set.This paper compares the features of the China and US environmental governance systems that need be understood by those working between the systems.Key features include:(1) common values which shape the environmental governance choices in both countries,but which may have different practical meanings in each country;(2) America's common law-based environmental governance system,and China's civil law system,which involves plan(s)as well as law;(3) America's Federal central-local system,and China's unitary central local system.This paper concludes by suggesting areas in which further comparative understanding may be of value,including:(1) better under standing of the role of plan and law in China's governance system;(2) comparing the American Federal-state agreement system for implementation of environmental law with the China central-local system of target responsibility agreements for plan implementation;(3) improving understanding of nongovernmental resources needed to assure compliance with environmental laws and plans;(4) identifying institutions that can coordinate central-local and cross-border environmental governance.

  13. Borders and border representations: Comparative approximations among the United States and Latin America

    Directory of Open Access Journals (Sweden)

    Marcos Cueva Perus

    2005-01-01

    Full Text Available This article uses a comparative approach regarding frontier symbols and myths among the United States, Latin America and the Caribbean. Although wars fought over frontiers have greatly diminished throughout the world, the conception of frontier still held by the United States is that of a nationalist myth which embodies a semi-religious faith in the free market and democracy. On the other hand, Latin American and Caribbean countries, whose frontiers are far more complex, have shown extraordinary stability for several decades. This paper points out the risks involved in the spread of United States´ notions of frontier which, in addition, go hand-in-hand with the problem of multicultural segmentation. Although Latin American and Caribbean frontiers may be stable, they are vulnerable to the infiltration of foreing frontier representations.

    Full Text Available Central America is an ideal region for comparative phylogeographic studies because of its intricate geologic and biogeographic history, diversity of habitats and dynamic climatic and tectonic history. The aim of this work was to assess the phylogeography of two rodents codistributed throughout Central America, in order to identify if they show concordant genetic and phylogeographic patterns. The synopsis includes four parts: (1 an overview of the field of comparative phylogeography; (2 a detailed review that describes how genetic and geologic studies can be combined to elucidate general patterns of the biogeographic and evolutionary history of Central America; and a phylogeographic analysis of two species at both the (3 intraspecific and (4 comparative phylogeographic levels. The last incorporates specific ecological features and evaluates their influence on the species’ genetic patterns. Results showed a concordant genetic structure influenced by geographic distance for both rodents, but dissimilar dispersal patterns due to ecological features and life history.

    In this study, the Palmer Drought Severity Index (PDSI) was used to analyze the average and extreme dry/wet states of Asia and North America from 1953 to 2003. The results indicate that the two continents underwent drying trends during this period. Compared with North America, Asia showed more severe drought trends. However, more significant and regular seasonal variation for drought was found in North America. The driest regions in Asia were located in the northern region of China, Mongolia, and eastern mid-Siberian plateau. Most regions in central North America were relatively wetter than other regions.The northern and southwestern regions of North America, as well as the Atlantic and Pacific coastal areas,experienced the most drought during this period. A sharp increase of the drought area and the number of extreme drought events took place from 1997 to 2003 in both Asia and North America. Severe drought events were more likely to occur during the summer on both continents. Asia had the most extreme drought events during July, but North America reached its highest drought frequency from June to September. In Asia, a persistent increasing trend of extreme drought emerged throughout the studied period. However,a more complex evolution of drought emerged in North America: a decreasing trend appeared before the mid-1960s and an increasing trend appeared after the late 1970s. A relatively steady dry/wet status was observed between the mid-1960s and the late 1970s. The role of exceptional, extreme drought events with respect to the La Nifia event was considered during 1997-2003.

  19. Forced genital cutting in North America: feminist theory and nursing considerations.

    This article will examine forced nontherapeutic genital cutting (FNGC) through the lens of feminist theory and in relation to the concept of social justice in nursing. I will address the underlying assumptions of feminism and how they apply to the two currently legal forms of FNGC in North America: male infant circumcision and intersex infant/child genital cutting. Through a literature review and critical analysis of these practices, I will illustrate the challenges they present when considering the role of nurses in promoting social justice. If feminism asserts that bodily integrity, autonomy, and fundamental human rights are essential components of gender equality, it follows that these must be afforded to all genders without discrimination. Historically, there have been few feminists who have made this connection, yet a growing and diverse movement of people is challenging the frameworks in which we consider genital cutting in our society. Nurses are positioned well to be at the forefront of this cause and have a clear ethical duty to advocate for the elimination of all forms of FNGC. PMID:24030105

    2012-06-01

    Full Text Available The main objective of the paper is to assess the impact of fiscal variables on private investment comparing some Latin-American economies to other advanced ones. For such purposes, the authors carry out an econometric analysis for the period 1990-2008. They make use of two dynamic panel models in which they group countries with similar characteristics and development levels. In one of them, they include Mexico, Brazil, Chile, Colombia and Uruguay; whereas in the second one the countries accounted for are the U.S., Canada, Spain, Korea, Ireland and Japan. They specify in both models an investment function using as arguments a wide range of variables, including those related with fiscal policy. From their results the authors infer that governments can, with higher spending, boost up the economy even when they finance spending with higher taxes. In Latin America, where income concentration is enormous, a proposal to boost up the economy through higher government expenditure financed with a progressive income tax, is even more justified.

  2. Cannabis policy reforms in the Americas: a comparative analysis of Colorado, Washington, and Uruguay.

    2014-07-01

    Legal reforms in the Americas are influencing the public debate on cannabis policy. Uruguay and the two US states of Colorado and Washington have taken steps to regulate and legitimize the production, distribution, and use of cannabis and its derivatives. Earlier experiences with medical cannabis in the United States and limited access and production models in Europe have been insightful. However, these reforms are going further still, venturing into a new area of cannabis policy. A lack of empirical evidence regarding the effects of such reforms poses a challenge for policymakers. These examples will inform the design and implementation of any future cannabis policies. Therefore, a clear understanding of the details of each jurisdiction is necessary in developing future legal changes. Literature comparing the models of Uruguay, Colorado, and Washington is thin. This paper is based on an exhaustive examination of the laws, regulations, and discussions with regulators and functionaries of each jurisdiction. The research and analysis herein will provide policymakers with a greater understanding of the laws and regulations relevant to legal cannabis in these three jurisdictions, as well as draw to their attention some potential impacts and challenges of cannabis reform that require additional consideration to ensure public safety and health.

    1997-09-01

    Full Text Available Neurocysticercosis is an important public health problem in South-Central America and South Asia. A review of the differences in epidemiological and clinical attributes of cysticercosis and taeniasis in South Central America and India, respectively, is undertaken in the present communication. Intestinal taeniasis is hyperendemic in several American countries. In comparison, the prevalence of Taenia solium infestation is lower in India. The clinical manifestations in several American neurocysticercosis series comprise epilepsy, intracranial hypertension and meningeal - racemose cysticercosis, in roughly equal proportions. An overwhelming majority of the Indian subjects present with seizures. The commonest pathological substrate of the disorder in Indian patients is the solitary parenchymal degenerating cyst. The reasons for the predominance of solitary forms in India, and of multilesional forms in South Central America are discussed. The magnitude of Taenia solium infestation and the frequency of pork consumption in a given population appear to influence the quantum of cyst load in affected individuals.

  5. Construction and harmonious development of urban-rural comparing financial systems based on comparative advantages theory

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    There exist differences between urban-rural financial systems. Generally, the development of urban financial industry has absolute advantages compared with rural financial industry. According to the Matthew Effect, the financial resources will flow into cities for higher benefit, so rural areas are unable to obtain absolute advantages. However, relative advantage theory of the comparative advantage theory provides an important way to observe respective advantage of both city and country. Therefore, there are comparative advantages for the development of financial industry in both urban and rural areas, The respective comparative advantages of urban-rural financial systems will supply greater efficiency than that in current dual pattern condition. Closely connected with China's financial development and reform and the fact of the recreation of urban-rural financial system, this paper tries to explain the comparative advantage of the urban-rural financial systems. The analysis of the comparative advantage between urban and rural finance is the clue for the boundary between urban-rural financial systems. This paper analyzes the current situation of urban.-rural financial system. Then it proposes some views and suggestions on how to develop and maintain these two systems as well as how to promote their coordinative development.

    This paper describes a comparative study of the climatology of large-scale traveling ionospheric disturbances (LSTIDs) over North America and China based on observations obtained in 2011-2012 using two GPS networks characterized by dense regional coverage. We identified a total of 390 LSTIDs in China and 363 events in North America. These can be categorized into three types, namely south, north, and westward propagating LSTIDs. The southward LSTIDs over North America show similar diurnal and seasonal variations to those of geomagnetic disturbances, but the southward LSTIDs over China do not show such variations. The occurrence of southward LSTIDs over China increases at ~1-2 h after the time of geomagnetic activity maximum; this increase lasts several hours until the geomagnetic minimum, which happens during the local evening. The southward LSTIDs over North America show a semiannual variation with two peaks in March and October, while the southward LSTIDs over China show a major peak in January. Northward LSTIDs occur much less frequently than their southward counterparts, and they are mainly observed in China. They mostly occur during geomagnetic activity maximum, indicating a possible relation with the degree of geomagnetic activity. Westward LSTIDs are seen in both regions during local sunrise and may be excited by the moving solar terminator. No relationship was found between these latter LSTIDs and the geomagnetic disturbances. The propagation direction of westward events changed from northwestward during winter solstice to southwestward at summer solstice. This is consistent with the seasonal orientation of the solar terminator.

    Full Text Available Abstract Background Taiwan has been dispatching an increasing number of short-term medical missions (STMMs to its allied nations to provide humanitarian health care; however, overall evaluations to help policy makers strengthen the impact of such missions are lacking. Our primary objective is to identify useful strategies by comparing STMMs to the South Pacific and Central America. Methods The data for the evaluation come from two main sources: the official reports of 46 missions to 11 countries in Central America and 25 missions to 8 countries in the South Pacific, and questionnaires completed by health professionals who had participated in the above missions. In Central America, STMMs were staffed by volunteer health professionals from multiple institutions. In the South Pacific, STMMs were staffed by volunteer health professionals from single institutions. Results In comparison to STMMs to Central America, STMMs to the South Pacific accomplished more educational training for local health providers, including providing heath-care knowledge and skills (p Conclusions Health-care services provided by personnel from multiple institutions are as efficient as those from single institutions. Proficiency in the native language and provision of education for local health-care workers are essential for conducting a successful STMM. Our data provide implications for integrating evidence into the deployment of STMMs.

  8. Historical atmospheric mercury emissions and depositions in North America compared to mercury accumulations in sedimentary records

    Science.gov (United States)

    Pirrone, Nicola; Allegrini, Ivo; Keeler, Gerald J.; Nriagu, Jerome O.; Rossmann, Ronald; Robbins, John A.

    Gold and silver production in North America (included United States, Canada and Mexico) released a large amount of mercury to the atmosphere until well into this century when mercury (Hg) amalgamation was replaced by cyanide concentration. Since then, emissions from industries have been the dominant anthropogenic sources of atmospheric Hg in North America as a whole. Past Hg emissions from gold and silver extractions in North America during the 1800s do not show a clear evidence of atmospheric deposition occurred at the coring sites considered in this study. Estimated atmospheric emissions of Hg in North America peaked in 1879 (at about 1708 t yr -1) and 1920 (at about 940 t yr -1), primarily due to Hg emissions from gold and silver mining. After the Great Economic Depression (1929) Hg emissions peaked again in the 1947 (274 t yr -1), in 1970 (325 t yr -1) and in 1989 (330 t yr -1) as result of increased Hg emissions from industrial sources, though improvements in the emissions control technology in United States and Canada have been substantial. Estimates of total atmospheric deposition fluxes of Hg to water and terrestrial receptors were in the range of 14.3-19.8 μg m -2 yr -1 in North America as a whole, and averaged 135 μg m -2 yr -1 (global background + local emissions) in the Great Lakes. These values were in good agreement with recent estimates reported in literature. The comparison of atmospheric Hg deposition fluxes with Hg accumulation rates in sediment cores suggests that atmospheric deposition was the major source of Hg entering the lakes system at coring sites, however, important contributions to Lake Ontario sediment cores sites from 1940 to 1970 were likely originated from local point sources (i.e. direct discharges).

    Full Text Available This study deals with one of the most important fundamental rules of criminal trial, both in the United States of America and in Romania, namely the right of the person accused of committing a crime to have a trial within a reasonable time. As regards the legal system of the United States of America, the author approached the issue from the perspective of the Constitution of the United States of America, respectively reviewing the legislative system of the State of Illinois. The presentation of the case law in this field had an important role in this review. As regards the legal system of Romania, the efforts to amend the legislation in order to ensure a reasonable time for carrying out the criminal proceedings are obvious even if sometimes, in this way, the applicability of other fundamental principles, such as the principle of finding out the truth, is restricted. The differences existing between the two penal legal systems are also obvious, after reading this study.

  12. Comparative Study of Basins within Palaeogene Seaway in East China and Cretaceous Seaway in North America and Its Reservoir Significance

    2007-01-01

    The well known Cretaceous seaway in North America was recognized in the middle of the last century and the Palaeogene seaway in East China was proposed by the author recently. The two seaways located on the opposite sides of North Pacific Ocean may be not a coincidence,and a comparative study was made in this paper. The results show that the two seaways inundated basins share several similarities particularly in basin origin,filling processes and reservoir facies. It is suggested that reservoir facies of estuarine sandstone and shelf bar sandstone related to sea level fluctuation,which are well developed in the Cretaceous seaway covered basins in North America might have been also developed here in Palaeogene seaway inundated basins in East China. Therefore it is worth paying more attention to finding these new reservoir facies on this side of the Pacific ocean. Evidences of sedimentology and ichnology indicate that good prospects are likely.

  15. The filmic emotion. A comparative analysis of film theories

    Directory of Open Access Journals (Sweden)

    Imanol Zumalde-Arregi, Ph.D.

    2011-01-01

    Full Text Available This article tries to explain the origins of the filmic emotion. Due to the lack of a widely agreed idea about the way film texts play with the emotional world of the empirical spectator, this work outlines the diverse arguments and approaches through which film theory has tried to explain the catalogue of emotions that a film can provoke in the spectator. This review reveals a conflict between the theories oriented to the spectator and context, and the theories focused on the text. There are, in fact, two approaches to evaluate the emotional effects provoked by films: the cultural studies approach, which is based on pragmatics and gender oriented theories, and focuses on the social and subjective conditions through which cinema is experienced, and the approach of structural semiotics and cognitive theory, which focuses on the way a film text tries to direct the spectator’s emotional experience. In the middle of these two approaches, the psychoanalytical theory conceives the filmic experience as a simulation of daily life.

  16. Willingness to Share Knowledge Compared with Selected Social Psychology Theories

    Full Text Available Knowledge is one of the key determinants in the growth and competitiveness of modern enterprises. Hence, it is essential to analyse the factors that induce employees to exchange knowledge. The problem of sharing an intangible asset — in this case, the knowledge of individuals — can be viewed from many perspectives: psychological, economic, organisational, sociological and technological. The aim of this article is to explore selected social psychology theories and to analyse the incentives for people to share knowledge. The article attempts to interpret the willingness to share knowledge through the Social Exchange Theory, the Social Impact Theory, the Theory of Reasoned Action and the Theory of Planned Behaviour. This analysis leads to the following conclusions: •we share our knowledge and expect a return; •we share our knowledge when we believe that the benefits of this action outweigh the costs; •we are pushed to share knowledge by the power of empathy; •workers’ willingness to share knowledge is influenced by three social processes: subordination, identification and internalisation; •the decision to share knowledge is preceded by an intention formed under the influence of an individual attitude towards that behaviour, subjective norms and perceived behavioural control; and •the decision to share knowledge is also influenced by additional components, including the knowledge and skills to implement this behaviour, environmental limitations, behavioural emphasis and habits.

    Full Text Available As a reflection of the ecological pressures associated with rapid modernization and globalization, the environment has become an enduring theme of public debate and protest in Latin America. Over the past decade, scholars have made increasing connections between such debate and a range of questions related to citizenship. Meanwhile, a discourse of ‘environmental citizenship’ has a growing prevalence in policy across the region. While these developments echo similar political and academic trends in the Global North, the Latin American context demands a unique set of theoretical and methodological approaches to studying the intersection of ecology and citizenship, sensitive to the specific historical, cultural, and ecological character of the region. We outline a research agenda spanning questions of land, identity and citizenship; environmental justice and de-colonization; social subjectivity and the state; urban natures and citizens; and the materiality/subjectivity of nature. This array of approaches points to a more acute conceptualization of citizenship, both in terms of its understanding of politics and its treatment of ecology; it also offers a point of view that recognizes citizens and natures as dynamic realities, which mutually condition each other in a sphere of ongoing contest.   Resumen: Medio ambiente y ciudadanía en América Latina: un nuevo paradigma para la teoría y práctica Como reflexión de los impactos ecológicos asociados con la modernización rápida y la globalización, el medio ambiente se ha transformado en un tema de debate y protesta constante en Latinoamérica.

Before now, the method has basically been a manual or hand methodwhich some engineers did not see a need for its use since there are many computer based packages in the analysis and design of slabs and other civil engineering structures. This paper presents a computer program that has adopted the yield line theory in the analysis of solid slabs. Two rectangular slabs of the same depth but differentdimensions were investigated. The Yield Line Theory was compared with two other analytical methods namely, Finite Element Method and Elastic Theory Method. The results obtained for a two-way spanning slab showed that the yield line theory is truly conservative, butincreasing the result by 25% caused the moment obtained to be very close to the results of the other two methods. Although it was still conservative, the check for deflections showed that it is reliable and economical in terms of reinforcement provision. For a one way spanning slab the results without any increment falls in between the two other methods with the Elastic method giving a conservative results. The paper concludes that the introduction of a computer-based yield line theory program will make the analytical method acceptable to design engineers in the developing countries of the world.

  13. Quantitative ethnobotany of palms in northwestern South America: a comparative analysis in Amazonia, Andes and Chocó

    DEFF Research Database (Denmark)

    Cámara-Leret, Rodrigo

    This Doctoral Thesis is the result of an interdisciplinary work between 2010-2014 to document and analyze the use patterns and traditional knowledge of palms (Arecaceae) in northwestern South America. The work is based on field data collected over 18 months in four countries (Colombia, Ecuador......, Peru and Bolivia), three ecoregions (Amazon, Andes, Chocó), three human groups (indigenous, mestizos, afro-americans), 55 Amerindian groups, 68 communities and 2201 informants. Altogether, 140 useful palm species, 2262 different uses and 87,886 use records were found. The Doctoral student conducted...... fieldwork collected more information than the existing literature on most of the analyzed scales, and represents the first empirical evidence that ethnobotanical knowledge is poorly documented in northwestern South America. Given our findings, we hope to stimulate the formulation of plans to systematically...

    Full Text Available This paper analyses the relationship between inequality and de facto regional economic integration during the last two decades in Latin America and East Asia Pacific regions, focusing on intra-regional exports. Globalization has been considered as a driving of inequality, although export-led growth models are associated with high economic growth rates. Export-led growth models have been more dynamic in East Asia than in Latin America, through the development of supply chain networks of intermediate and final goods. Research questions explore the relation between inequality and patterns of de facto intra-regional trade. Empirical analysis uses a fixed effects panel data with Heteroskedasticity and Autocorrelation Consistent (HAC covariance matrix. Results showed that increments in regional intra-trade are associated with reductions of inequality, more in East Asia Pacific than in Latin America. The contribution of this paper is the introduction of intra-regional trade as a new factor that is negatively associated with inequality.

    Experimental data on DNA melting in the presence of magnesium and calcium ions are compared with the calculated results by the "ligand" theory and "condensation" theory developed by de Marky and Manning (TMM). The maximum is observed in TMM dependences of DNA melting temperature change (delta Tm) on the ion concentration (D), absent in the experimental dependences and the "ligand" theory. The main cause of the discrepancy of calculated and experimental dependences delta Tm (D) is the fact that TMM neglects Na+ ion effects on Me2+ ion binding ("condensation") to DNA. The results obtained show that in comparison with TMM the "ligand" theory describes more adequately DNA helix-coil transition in the presence of divalent metal ions in the region of both low and high ionic strengths of solution.

    Comparative analysis of nonhuman animal communication systems and their complexity, particularly in comparison to human language, has been generally hampered by both a lack of sufficiently extensive data sets and appropriate analytic tools. Information theory measures provide an important quantitative tool for examining and comparing communication systems across species. In this paper we use the original application of information theory, that of statistical examination of a communication system's structure and organization. As an example of the utility of information theory to the analysis of animal communication systems, we applied a series of information theory statistics to a statistically categorized set of bottlenose dolphin Tursiops truncatus, whistle vocalizations. First, we use the first-order entropic relation in a Zipf-type diagram (Zipf 1949 Human Behavior and the Principle of Least Effort) to illustrate the application of temporal statistics as comparative indicators of repertoire complexity, and as possible predictive indicators of acquisition/learning in animal vocal repertoires. Second, we illustrate the need for more extensive temporal data sets when examining the higher entropic orders, indicative of higher levels of internal informational structure, of such vocalizations, which could begin to allow the statistical reconstruction of repertoire organization. Third, we propose using 'communication capacity' as a measure of the degree of temporal structure and complexity of statistical correlation, represented by the values of entropic order, as an objective tool for interspecies comparison of communication complexity. In doing so, we introduce a new comparative measure, the slope of Shannon entropies, and illustrate how it potentially can be used to compare the organizational complexity of vocal repertoires across a diversity of species. Finally, we illustrate the nature and predictive application of these higher-order entropies using a preliminary

  18. Comparative assessment of status and opportunities for carbon Dioxide Capture and storage and Radioactive Waste Disposal In North America

    2011-07-22

    Aside from the target storage regions being underground, geologic carbon sequestration (GCS) and radioactive waste disposal (RWD) share little in common in North America. The large volume of carbon dioxide (CO{sub 2}) needed to be sequestered along with its relatively benign health effects present a sharp contrast to the limited volumes and hazardous nature of high-level radioactive waste (RW). There is well-documented capacity in North America for 100 years or more of sequestration of CO{sub 2} from coal-fired power plants. Aside from economics, the challenges of GCS include lack of fully established legal and regulatory framework for ownership of injected CO{sub 2}, the need for an expanded pipeline infrastructure, and public acceptance of the technology. As for RW, the USA had proposed the unsaturated tuffs of Yucca Mountain, Nevada, as the region's first high-level RWD site before removing it from consideration in early 2009. The Canadian RW program is currently evolving with options that range from geologic disposal to both decentralized and centralized permanent storage in surface facilities. Both the USA and Canada have established legal and regulatory frameworks for RWD. The most challenging technical issue for RWD is the need to predict repository performance on extremely long time scales (10{sup 4}-10{sup 6} years). While attitudes toward nuclear power are rapidly changing as fossil-fuel costs soar and changes in climate occur, public perception remains the most serious challenge to opening RW repositories. Because of the many significant differences between RWD and GCS, there is little that can be shared between them from regulatory, legal, transportation, or economic perspectives. As for public perception, there is currently an opportunity to engage the public on the benefits and risks of both GCS and RWD as they learn more about the urgent energy-climate crisis created by greenhouse gas emissions from current fossil-fuel combustion practices.

    Zayakin, Andrey V.

    2011-01-17

    This Thesis is dedicated to a comparison of the two means of studying the electromagnetic properties of the QCD vacuum - holography and resummed field theory. I compare two classes of distinct models for the dynamics of the condensates. The first class consists of the so-called holographic models of QCD. Based upon the Maldacena conjecture, it tries to establish the properties of QCD correlation functions from the behavior of classical solutions of field equations in a higher-dimensional theory. Yet in many aspects the holographic approach has been found to be in an excellent agreement with data. These successes are the prediction of the very small viscosity-to-entropy ratio and the predictions of meson spectra up to 5% accuracy in several models. On the other hand, the resummation methods in field theory have not been discarded so far. Both classes of methods have access to condensates. Thus a comprehensive study of condensates becomes possible, in which I compare my calculations in holography and resummed field theory with each other, as well as with lattice results, field theory and experiment. I prove that the low-energy theorems of QCD keep their validity in holographic models with a gluon condensate in a non-trivial way. I also show that the so-called decoupling relation holds in holography models with chiral and gluon condensates, whereas this relation fails in the Dyson-Schwinger approach. On the contrary, my results on the chiral magnetic effect in holography disagree with the weak-field prediction; the chiral magnetic effect (that is, the electric current generation in a magnetic field) is three times less than the current in the weakly-coupled QCD. The chiral condensate behavior is found to be quadratic in external field both in the Dyson-Schwinger approach and in holography, yet we know that in the exact limit the condensate must be linear, thus both classes of models are concluded to be deficient for establishing the correct condensate behaviour in the

    This dissertation examines the reinvention of theoretical physics in the United States through pedagogical means after World War II. Physics graduate student enrollments ballooned immediately after the war. The unprecedented enrollments forced questions of procedures and standards for graduate training as never before. At the same time, the crush of numbers spurred an increased bureaucratization and, at least some American physicists feared, a different system of values than what had prevailed during the quieter interwar period. Out of these new bureaucratic and pedagogical developments, theoretical physics became a recognized specialty within American physics, surrounded by new ideas about what theory was for and how students should be trained to do it. Two case studies focus on developments within theoretical physics after the war, using pedagogy as a lens through which to understand the links between practices and practitioners. Within nuclear and particle physics, as Part II discusses, young graduate stud...

    Listening and reading are two receptive skills in language learning and language use . Although their modalities differ , listening and reading share a number of cognitive processes required for language comprehension this has resulted in some commonalities in research emphases for the two skills . One such focus is the role of metacognition in self-regulated learning and comprehension performance . In this article theory postulated for metacognition and its manifestation in listening and reading are discussed . The article also reviews selected studies conducted in two important dimensions of metacognition , namely metacognitive knowledge and strategy use , and the impact that metacognitive instruction has on listening and reading comprehension performance . Results from the review for each skill are synthesised and compared in order to draw insights into the processes of learning to listen and read in another language . Based on this comparative review , the authors offer suggestions for enhancing process-based instructional practices in the language classroom and identify possible directions for future research into the role of metacognition in listening and reading specifically as well as second language comprehension as a whole .

    Comparative decision making process is widely used to identify which option (system, product, service, etc.) has smaller environmental footprints and for providing recommendations that help stakeholders take future decisions. However, the uncertainty problem complicates the comparison and the decision making. Probability-based decision support in LCA is a way to help stakeholders in their decision-making process. It calculates the decision confidence probability which expresses the probability of a option to have a smaller environmental impact than the one of another option. Here we apply the reliability theory to approximate the decision confidence probability. We compare the traditional Monte Carlo method with a reliability method called FORM method. The Monte Carlo method needs high computational time to calculate the decision confidence probability. The FORM method enables us to approximate the decision confidence probability with fewer simulations than the Monte Carlo method by approximating the response surface. Moreover, the FORM method calculates the associated importance factors that correspond to a sensitivity analysis in relation to the probability. The importance factors allow stakeholders to determine which factors influence their decision. Our results clearly show that the reliability method provides additional useful information to stakeholders as well as it reduces the computational time. PMID:26815724

    Full Text Available This article reviews the concepts involved in the problem of foreign debt. From a Monetary Keynesian approach, it analyzes the differences and similarities between the Kindleberger model, the German Marxist view, the orthodox theory of debt cycles held by the World Bank and Latin American structuralism. Finally, there are some elements of German Monetary Keynesianism in an integration of financial factors and growing microeconomic concern for insti tutions. In the practical field there is a consideration of the policies required to solve the debt problem which each school of thought would recommend. The author supports the thesis of Riese, founder of the Berlin School: in view of their limi ted monetary and productive potential, developing countries are unable to counter the devaluation strategies of the leading industrial countries... the strategies of devaluation of the underdeveloped countries and the consolidation of the balance of payments as the ruling monetary policy, much promoted by recent academic literature, are doomed to fail.

    alpha-Amylase is one of the major enzymes present in the seeds of both Araucaria species of South America and it initiates starch hydrolysis during germination and early seedling growth. The pattern of the multiple forms of alpha-amylase of the two Araucaria species was investigated by electrophoresis and isoelectrofocusing of the native enzyme in polyacrylamide gels. The enzyme forms were compared in the embryo and megagametophyte of quiescent seeds and of seeds imbibed for 18, 48, and 90 hours. Specific alpha-amylase enzyme forms appear and disappear during these imbibition periods showing both similarities and differences between tissues and species. Before imbibition, there are five alpha-amylase forms identical in both tissues, but different between species. After 18 hours of imbibition, there are two enzyme forms in both tissues of Araucaria araucana seeds, only one form in the embryo of Araucaria angustifolia but two forms in the megagametophyte of this specie. After 48 hours of seed imbibition, most of the enzyme forms present in quiescent seeds reappear. At 90 hours of imbibition different enzyme forms are detected in the embryo with respect to the gametophyte. The changes in form patterns of alpha-amylase are discussed according to a possible regulation of gene expression by endogenous gibberellins. PMID:16664944

    1997-08-01

    The blade element momentum (BEM) model is still used in many aerodynamic and aeroelastic models for design and load calculations. This is due to its simplicity, robustness, computational speed and good accuracy for a wide range of applications. The question about accuracy is however closely connected to the airfoil section data and therefore correlation/lack of correlation with experimental results can both be due to the specific input data used and due to the induced velocity field predicted by the BEM method. It is also well-known that the BEM method for some applications is used under operational conditions that violates the assumptions made for the development of the model, e.g. operation in yaw and operation at high loading. The main objective with the present study is to investigate this part of the BEM method (the momentum strip theory MST) on which the determination of the induced velocities is based. This is done by comparing the results of the MST model with velocities predicted on basis of the Navier Stokes equations for the flow through an actuator disc. (au)

Rather than just imitating, reacting, or adjusting to the paradigms of modernity (and globalization), in the nineteenth century and early twentieth, the region elaborated and created modernity.

In particular, self-regard tracks social status to regulate behavioral assertiveness, augmenting or diminishing it to optimize performance in such contests. Hierometer theory also offers a conceptual counterpoint that helps resolve ambiguities in sociometer theory, which offers a complementary account of self-regard's evolutionary function. In two large-scale cross-sectional studies, we operationalized theoretically relevant variables at three distinct levels of analysis, namely, social (relations: status, inclusion), psychological (self-regard: self-esteem, narcissism), and behavioral (strategy: assertiveness, affiliativeness). Correlational and mediational analyses consistently supported hierometer theory, but offered only mixed support for sociometer theory, including when controlling for confounding constructs (anxiety, depression). We interpret our results in terms of a broader agency-communion framework. PMID:27065896

Hierometer theory also offers a conceptual counterpoint that helps resolve ambiguities in sociometer theory, which offers a complementary account of self-regard’s evolutionary function. In two large-scale cross-sectional studies, we operationalized theoretically relevant variables at three distinct levels of analysis, namely, social (relations: status, inclusion, psychological (self-regard: self-esteem, narcissism, and behavioral (strategy: assertiveness, affiliativeness. Correlational and mediational analyses consistently supported hierometer theory, but offered only mixed support for sociometer theory, including when controlling for confounding constructs (anxiety, depression. We interpret our results in terms of a broader agency-communion framework.

  2. Comparing brain networks of different size and connectivity density using graph theory.

    Directory of Open Access Journals (Sweden)

    Bernadette C M van Wijk

    Full Text Available Graph theory is a valuable framework to study the organization of functional and anatomical connections in the brain. Its use for comparing network topologies, however, is not without difficulties. Graph measures may be influenced by the number of nodes (N and the average degree (k of the network. The explicit form of that influence depends on the type of network topology, which is usually unknown for experimental data. Direct comparisons of graph measures between empirical networks with different N and/or k can therefore yield spurious results. We list benefits and pitfalls of various approaches that intend to overcome these difficulties. We discuss the initial graph definition of unweighted graphs via fixed thresholds, average degrees or edge densities, and the use of weighted graphs. For instance, choosing a threshold to fix N and k does eliminate size and density effects but may lead to modifications of the network by enforcing (ignoring non-significant (significant connections. Opposed to fixing N and k, graph measures are often normalized via random surrogates but, in fact, this may even increase the sensitivity to differences in N and k for the commonly used clustering coefficient and small-world index. To avoid such a bias we tried to estimate the N,k-dependence for empirical networks, which can serve to correct for size effects, if successful. We also add a number of methods used in social sciences that build on statistics of local network structures including exponential random graph models and motif counting. We show that none of the here-investigated methods allows for a reliable and fully unbiased comparison, but some perform better than others.

    Nucleic acids are biopolymers that carry genetic information and are also involved in various gene regulation functions such as gene silencing and protein translation. Because of their negatively charged backbones, nucleic acids are polyelectrolytes. To adequately understand nucleic acid folding and function, we need to properly describe its i) polymer/polyelectrolyte properties and ii) associating ion atmosphere. While various theories and simulation models have been developed to describe nucleic acids and the ions around them, many of these theories/simulations have not been well evaluated due to complexities in comparison with experiment. In this review, I discuss some recent experiments that have been strategically designed for straightforward comparison with theories and simulation models. Such data serve as excellent benchmarks to identify limitations in prevailing theories and simulation parameters. PMID:26482088

  5. Validating Monin Obukhov theory and comparing published with a new stability correction over snow

    Schlögl, Sebastian; Mott, Rebecca; Lehning, Michael

    Modeling turbulent fluxes over a homogenous snow cover is already a challenging task because atmospheric stability has often a strong but difficult to quantify influence. Monin Obukhov theory and stability corrections are often applied over complex terrain and non-equilibrium boundary layers with the result of unknown errors. Four different data sets collected with 3-D ultrasonics over snow-covered terrain of varying complexity in the Swiss Alps, were analyzed in order to 1) test the Monin-Obukhov theory, 2) evaluate the performance of different published parameterization schemes of the stability correction and 3) develop a new simple approach for a stability correction over snow. We first conducted a comprehensive analysis of the existence of a constant flux layer by analyzing the vertical evolution of turbulent sensible heat fluxes at the four different test sites. Three already published stability corrections were evaluated and compared with the assumption of a neutrally forced boundary layer. Non-parameterized stability correction values were directly calculated from measured friction velocities. Those values allowed a comparison between the Eddy Covariance method and the Monin Obukhov bulk formulation and a quantification of the uncertainty of modeling turbulent fluxes using the Monin Obukhov approach. Furthermore, the independent uncertainty that is introduced to energy balance modeling by applying a parameterization of the non-parameterized stability correction values was analyzed. This parameterization was conducted (a) assuming a linear dependence on the stability parameter and (b) assuming a two-parameter dependence on buoyancy and shear terms in a first order statistical model. Our results show that the constant flux layer occurs totally in 10 % of the time, particularly in the morning.

    We consider the two main classification methods of D-brane charges via K-theory, in type II superstring theory with vanishing B-field: the Gysin map approach and the one based on the Atiyah-Hirzebruch spectral sequence. Then, we find out an explicit link between these two approaches: the Gysin map provides a representative element of the equivalence class obtained via the spectral sequence. We also briefly discuss the case of rational coefficients, characterized by a complete equivalence between the two classification methods.

    2015-09-03

    We report a combined experimental and theoretical study on the optoelectronic properties of α-SnWO4 for UV-Vis excitation. The experimentally measured values for thin films were systematically compared with high-accuracy density functional theory and density functional perturbation theory using the HSE06 functional. The α-SnWO4 material shows an indirect bandgap of 1.52 eV with high absorption coefficient in the visible-light range (>2 × 105 cm−1). The results show relatively high dielectric constant (>30) and weak diffusion properties (large effective masses) of excited carriers.

Focussing mainly on the initial stages of these revolutionary events it will be shown that: a in all three cases the path towards a revolutionary break with the Old Regime was anything but predetermined and that b particularly in the Americas the question of the Nation was not settled at all by the revolutionaries. This is one of the most important explanations why later onwards Nation –and State– building in the Americas, both in Latin America and in North-America, became anything but a smooth and linear process.Este artículo compara las revoluciones francesa y estadounidense del último tercio del siglo XVIII con la independencia y la revolución en la América Latina de inicios del siglo XIX, bajo una perspectiva teórica particular.

    Full Text Available Introduction: Rates of both TB/HIV co-infection and multi-drug-resistant (MDR TB are increasing in Eastern Europe (EE. Data on the clinical management of TB/HIV co-infected patients are scarce. Our aim was to study the clinical characteristics of TB/HIV patients in Europe and Latin America (LA at TB diagnosis, identify factors associated with MDR-TB and assess the activity of initial TB treatment regimens given the results of drug-susceptibility tests (DST. Material and Methods: We enrolled 1413 TB/HIV patients from 62 clinics in 19 countries in EE, Western Europe (WE, Southern Europe (SE and LA from January 2011 to December 2013. Among patients who completed DST within the first month of TB therapy, we linked initial TB treatment regimens to the DST results and calculated the distribution of patients receiving 0, 1, 2, 3 and ≥4 active drugs in each region. Risk factors for MDR-TB were identified in logistic regression models. Results: Significant differences were observed between EE (n=844, WE (n=152, SE (n=164 and LA (n=253 for use of combination antiretroviral therapy (cART at TB diagnosis (17%, 40%, 44% and 35%, p<0.0001, a definite TB diagnosis (culture and/or PCR positive for Mycobacterium tuberculosis; 47%, 71%, 72% and 40%, p<0.0001 and MDR-TB prevalence (34%, 3%, 3% and 11%, p <0.0001 among those with DST results. The history of injecting drug use [adjusted OR (aOR = 2.03, (95% CI 1.00–4.09], prior TB treatment (aOR = 3.42, 95% CI 1.88–6.22 and living in EE (aOR = 7.19, 95% CI 3.28–15.78 were associated with MDR-TB. For 569 patients with available DST, the initial TB treatment contained ≥3 active drugs in 64% of patients in EE compared with 90–94% of patients in other regions (Figure 1a. Had the patients received initial therapy with standard therapy [Rifampicin, Isoniazid, Pyrazinamide, Ethambutol (RHZE], the corresponding proportions would have been 64% vs. 86–97%, respectively (Figure 1b.

  2. Comparative Accumulation of Injury from X-, Gamma and Neutron Irradiation - The Position of Theory and Experiment

    International Nuclear Information System (INIS)

    The theoretical formulation of the process of accumulation of radiation injury postulates that the injury is divided into two types, one of which recovers with time after irradiation, and the other of which is permanent. Experimentally it has been shown that both types of injury do exist independently and have magnitudes reasonably in conformity with theory. For a number of types of permanent injury the neutron/gamma RBE is the same as that for acute radiation death. Until recently, the theory has been unable to predict correctly the accumulation of injury in animals exposed to chronic irradiation. Recent studies, however, based on short-term (∼60 d) chronic LD50 studies with X-rays, have shown that the kinetics of recovery from the chronic injury are not necessarily those indicated by split-dose measurements; When the correct kinetics of recovery are used, the build-up of radiation injury is correctly predicted. For such limited-time exposures, the neutron/gamma RBE is the same as that for acute radiation death; hence, it is probable that the kinetics of recovery from neutron irradiation injury are qualitatively similar to those for X-ray injury. For long-term chronic exposures (> 5 months) the neutron/gamma RBE for accumulation of injury increases sharply over that for acute radiation death, and no satisfactory theory is available to predict the accumulation of injury from any kind of irradiation. For the short-term exposures however, the knowledge of the kinetics of recovery has advanced to the point where the biological basis of recovery and failure to recover can be investigated effectively.

  7. A Comparative Study of Three Inverse Kinematic Methods of Serial Industrial Robot Manipulators in the Screw Theory Framework

    Directory of Open Access Journals (Sweden)

    Emre Sariyildiz

    2011-11-01

    Full Text Available In this paper, we compare three inverse kinematic formulation methods for the serial industrial robot manipulators. All formulation methods are based on screw theory. Screw theory is an effective way to establish a global description of rigid body and avoids singularities due to the use of the local coordinates. In these three formulation methods, the first one is based on quaternion algebra, the second one is based on dual‐quaternions, and the last one that is called exponential mapping method is based on matrix algebra. Compared with the matrix algebra, quaternion algebra based solutions are more computationally efficient and they need less storage area. The method which is based on dual‐quaternion gives the most compact and computationally efficient solution. Paden‐Kahan sub‐problems are used to derive inverse kinematic solutions. 6‐DOF industrial robot manipulator's forward and inverse kinematic equations are derived using these formulation methods. Simulation and experimental results are given.

    In the past 30 years, the rates of incarceration and recidivism for women in the United States have increased dramatically. Choice Theory® Connections (CTC) is a gender-tailored pre-release intervention program based on Choice Theory® (Glasser, 1999), and designed to achieve meaningful and sustainable cognitive and behavioral change. This evaluation examines CTC among 96 female participants in a California state prison enrolled in an introductory (n = 58) or advanced (n = 38) course. CTC significantly improved perceived stress, mindfulness, emotion regulation, impulsivity, and well-being on completion; effects were stronger for the introductory cohort, but significant effects also emerged for the advanced cohort. In addition, participants in the advanced cohort reported better scores at baseline, demonstrating the effects of prolonged engagement with the intervention. Results suggest that CTC can improve incarcerated women's well-being pre-release, a strong predictor of recidivism post-release. Further study and wider use of CTC are encouraged. PMID:24441032

    2013-09-15

    The paper discusses social impact assessments (SIA) for mining projects in light of the international principles and guidelines for such assessments and the academic literature in the field. The data consist of environmental impact assessment (EIA) programmes and reports for six mining projects that have started up in northern Finland in the 2000s. A first observation is that the role of the SIAs in the EIA programmes and reports studied was quite minor: measured in number of pages, the assessments account for three or four percent of the total. This study analyses the data collection, research methodology and conceptual premises used in the SIAs. It concludes that the assessments do not fully meet the high standards of the international principles and guidelines set out for them: for example, elderly men are over-represented in the data and no efforts were made to identify and bring to the fore vulnerable groups. Moreover, the reliability of the assessments is difficult to gauge, because the qualitative methods are not described and where quantitative methods were used, details such as non-response rates to questionnaires are not discussed. At the end of the paper, the SIAs are discussed in terms of Jürgen Habermas' theory of knowledge interests, with the conclusion that the assessments continue the empirical analytical tradition of the social sciences and exhibit a technical knowledge interest. -- Highlights: • Paper investigates social impact assessments in Finnish mining projects. • Role of social impact assessment is minor in whole EIA-process. • Mining SIAs give the voice for elderly men, vulnerable groups are not identified. • Assessment of SIAs is difficult because of lacking transparency in reporting. • SIAs belong to empirical analytical tradition with technical knowledge interest.

Pertinent national education policies in countries receiving aid, in particular, are formed and implemented in a complex nexus. Cultural and context sensitivity can be stimulated through a thorough understanding of this confluence, which subsequently can enable the different policy agents, which function at this meeting point, collaborate to alleviate some of the educational challenges. Comparative and international education, in this respect, has a significant role to play.

Progress in our capabilities to build models for the computer simulation of polymers from the detailed atomistic scale up to coarse-grained mesoscopic models, together with the ever-improving performance of computers, have led to important insights from computer simulations into the structural and dynamic properties of amorphous polymers. Structurally, chain connectivity introduces a range of length scales from that of the chemical bond to the radius of gyration of the polymer chain covering 2-4 orders of magnitude. Dynamically, this range of length scales translates into an even larger range of time scales observable in relaxation processes in amorphous polymers ranging from about 10-13 to 10-3 s or even to 103 s when glass dynamics is concerned. There is currently no single simulation technique that is able to describe all these length and time scales efficiently. On large length and time scales basic topology and entropy become the governing properties and this fact can be exploited using computer simulations of coarse-grained polymer models to study universal aspects of the structure and dynamics of amorphous polymers. On the largest length and time scales chain connectivity is the dominating factor leading to the strong increase in longest relaxation times described within the reptation theory of polymer melt dynamics. Recently, many of the universal aspects of this behaviour have been further elucidated by computer simulations of coarse-grained polymer models. On short length scales the detailed chemistry and energetics of the polymer are important, and one has to be able to capture them correctly using chemically realistic modelling of specific polymers, even when the aim is to extract generic physical behaviour exhibited by the specific chemistry. Detailed studies of chemically realistic models highlight the central importance of torsional dynamics in

  16. Revisiting the formative works on the moving contact line to connect and compare modern theories

    The motion of a contact line is examined, and comparisons drawn, for a variety of proposed models in the literature. We provide an overview and extension of the original work on the moving contact line problem to elucidate and motivate some of the proposed methods to alleviate the multivalued velocity and nonintegrable stress and pressure singularities, offering a simple introduction to those unfamiliar with the situation and a contemporary look at the early work. We then compare a number of models from the literature in the classic prototype system of spreading of a thin two-dimensional droplet on a planar substrate, namely a variety of slip, disjoining pressure and interface formation models, the latter a sophisticated and complex model introduced by Shikhmurzaev, which differentiates itself from classical models through accounting for a variation in surface layer quantities and having finite-time surface tension relaxation. The thin droplet system utilising a long-wave model for the droplet thickness in a ...

    Properties of ferrofluid bilayer (modeled as a system of two planar layers separated by a distance h and each layer carrying a soft sphere dipolar liquid) are calculated in the framework of inhomogeneous Ornstein-Zernike equations with reference hypernetted chain closure (RHNC). The bridge functions are taken from a soft sphere (1/r(12)) reference system in the pressure-consistent closure approximation. In order to make the RHNC problem tractable, the angular dependence of the correlation functions is expanded into special orthogonal polynomials according to Lado. The resulting equations are solved using the Newton-GRMES algorithm as implemented in the public-domain solver NITSOL. Orientational densities and pair distribution functions of dipoles are compared with Monte Carlo simulation results. A numerical algorithm for the Fourier-Hankel transform of any positive integer order on a uniform grid is presented. PMID:25173007

    Different variants of the Uzawa algorithm are compared with one another. The comparison is performed for the case in which this algorithm is applied to large-scale systems of linear algebraic equations. These systems arise in the finite-element solution of the problems of elasticity theory for incompressible materials. A modification of the Uzawa algorithm is proposed. Computational experiments show that this modification improves the convergence of the Uzawa algorithm for the problems of solid mechanics. The results of computational experiments show that each variant of the Uzawa algorithm considered has its advantages and disadvantages and may be convenient in one case or another. PMID:27595019

    Full Text Available It is argued that Latin America contributed to modernity and the spread of what literature has called «the modern West». Rather than just imitating, reacting, or adjusting to the paradigms of modernity (and globalization, in the nineteenth century and early twentieth, the region elaborated and created modernity. This can be seen in two related but different processes: the formation of the Nation-State and the conceptualization of the Nation. While Latin America did, of course, look at Europe and the United States as possible models and attempted to emulate someof their modernity, no Latin American country seriously believed that they could reproduce Europe or the United States. Rather, in the context of post-colonialism, the region pioneered some of the precepts of modernity. The result was, as these brief comparisons with Europe and the United States suggest, a different path to modernity that later, in the twentieth century, one could find elsewhere in the global system.Se ha argumentado que América Latina no contribuyó a la modernidad y la expansión de lo que la literatura ha llamado «el Occidente moderno». Sin embargo, en lugar de sólo imitar, reaccionar o ajustarse a los paradigmas de la modernidad (y de la globalización, la región elaboró y creó modernidad durante el siglo XIX e inicios del siglo XX. Esto puede observarse en dos procesos distintos pero relacionados entre sí: la formación del Estado-Nación y la conceptualización de la Nación. Aun cuando América Latina sí miró a Europa y a Estados Unidos (EE.UU. como posibles modelos e incluso intentó emular algo de su modernidad, ningún país latinoamericano creyó seriamente que podría reproducir a Europa o a EE.UU. Más bien, en el contexto del poscolonialismo, la región fue pionera en algunos de los preceptos de modernidad. El resultado fue, como estas breves comparaciones con Europa y EE.UU. sugieren, un camino distinto a la modernidad que posteriormente, durante

    Abraham-Silver, Linda M.

    2005-11-01

    The study was designed to identify the beliefs held by visitors to natural history museums with respect to evolution and its mechanism. Visitors' levels of rejection and acceptance of evolutionary theory, their associated explanatory frameworks, and understanding of the nature of biological evolution were examined to determine whether differences existed between populations of museum visitors in the United States, Australia, Canada, and Great Britain. Data were collected at three natural history museums located outside of the United States and compared with existing data from previous studies conducted using the same methodology in American natural history museums. One hundred sixty-one museum visitors were interviewed in person in the non-U.S. sites; their interviews were tape recorded, transcribed, coded, and analyzed (using primarily chi-square) to identify similarities, patterns, and relationships among the data sets. Museum visitors outside of the United States demonstrated much lower levels of rejection of evolutionary theory when compared with data collected in the U.S. museums (an overall 2% rate of rejection was observed in the non-U.S. sample, while a 9.5% rejection rate was observed in the American sample). Surprising results included the finding that non-U.S. individuals held similar levels of naive conceptions with regard to the nature of evolutionary theory and the sequence of geologic time when compared with their American counterparts. Less than half of all museum visitors interviewed outside of the United States were able to describe natural selection, the mechanism by which evolution is thought to operate. Study participants showed consistent and deeply held tendencies to apply teleological or Lamarkian explanations to describe the mechanism for evolutionary change. Significant correlations between participants' age, their level of education, and their rejection or acceptance of evolution were not found among the data derived from these non

Em cada país constatam-se dinâmicas muito específicas da relação público/privado em seus respectivos sistemas de ensino superior. Em contraste com o Brasil, onde a expansão do setor privado iniciou-se em meados dos anos 60 e retraiu-se ao longo da década de 80, nos demais países, o crescimento absoluto e relativo das matrículas no setor privado, além de mais recente, ainda não apresentou sinais de esgotamento. Diferenças detiming na expansão do setor privado nos cinco países suscitam questões relevantes sobre a oportunidade da abertura do ensino superior para o mercado e sobre a relação do Estado com os respectivos sistemas nacionais, temas, sem dúvida, centrais no debate contemporâneo sobre ensino superior na América Latina.The article treats the relationship between the public and private sectors in five national systems of higher education: Argentina, Brazil, Chile, Colombia and Mexico. In each country there are very specific dynamics in the public/private relationship and their respective higher education systems. In contrast with Brazil where the expansion of the private sector began the mid 60s and contracted during the 80s, in the other countries the absolute and relative growth of enrollments in the private sector, in addition to being more recent, still shows no signs of exhaustion. Differences in timing in the expansion of the private sector in the five countries invite relevant questions about the opportunity for opening up higher education to the market and about the relationship with the State with the respective national systems. These issues doubtlessly are central in the contemporary debate on higher education in Latin America.

  7. Vanillin and isovanillin: Comparative vibrational spectroscopic studies, conformational stability and NLO properties by density functional theory calculations

    Science.gov (United States)

    Balachandran, V.; Parimala, K.

    This study is a comparative analysis of FT-IR and FT-Raman spectra of vanillin (3-methoxy-4-hydroxybenzaldehyde) and isovanillin (3-hydroxy-4-methoxybenzaldehyde). The molecular structure, vibrational wavenumbers, infrared intensities, Raman scattering activities were calculated for both molecules using the B3LYP density functional theory (DFT) with the standard 6-311++G∗∗ basis set. The computed values of frequencies are scaled using multiple scaling factors to yield good coherence with the observed values. The calculated harmonic vibrational frequencies are compared with experimental FT-IR and FT-Raman spectra. The geometrical parameters and total energies of vanillin and isovanillin were obtained for all the eight conformers (a-h) from DFT/B3LYP method with 6-311++G∗∗ basis set. The computational results identified the most stable conformer of vanillin and isovanillin as in the "a" form. Non-linear properties such as electric dipole moment (μ), polarizability (α), and hyperpolarizability (β) values of the investigated molecules have been computed using B3LYP quantum chemical calculation. The calculated HOMO and LUMO energies show that charge transfer occurs within the molecules.

    We have made careful measurements of Stark resonances in 7Li Rydberg states above and below the classical saddle point to test various theories and to obtain a precise calibration of the electric field. Rydberg states were populated by two-step diode laser excitation to the 3 2S state followed by He-Ne or diode laser excitation to Stark sublevels near the n=15 manifold energy. Calibration was performed by comparing measured resonance positions with theoretical results. For zero-field energies, the theoretical calculations were made using quantum defect parameters obtained by fitting available spectral data on Li, and from recent polarization model results of Drachman and Bhatia [Phys. Rev. A 51, 2926 (1995)]. Three theoretical methods were used: (1) matrix diagonalization over a basis of spherical coordinate states, for which the precision declines as one approaches the saddle point; (2) frame transformation theory, which makes very economical use of computer resources but is not reliable beyond a precision of about 500 ppm in an electric field; (3) a recently developed R-matrix method. The last of these was most accurate and, like the second, could be used both below and above the saddle point. From the measured resonance positions and an optimum set of Li quantum defect parameters, the R-matrix calculations provided a calibration of the electric field to about +/- 2 ppm +/-4 mV/cm. We briefly discuss certain refinements and shortcomings of the other two theoretical methods, and the special procedures used to obtain high accuracy with the R-matrix method.

    Full Text Available Abstract Background Scientifically rigorous general population-based studies comparing chiropractic with primary-care medical patients within and between countries have not been published. The objective of this study is to compare care seekers of doctors of chiropractic (DCs and general practitioners (GPs in the United States and Canada on a comprehensive set of sociodemographic, quality of life, and health-related variables. Methods Data are from the Joint Canada/U.S. Survey of Health (JCUSH, 2002–03, a random sample of adults in Canada (N = 3505 and the U.S. (N = 5183. Respondents were categorized according to their pattern of health-care use in the past year. Distributions, percentages, and estimates (adjusted odds ratios weighted to reflect the complex survey design were produced. Results Nearly 80% of respondents sought care from GPs; 12% sought DC care. Compared with GP only patients, DC patients in both countries tend to be under 65 and white, with arthritis and disabling back or neck pain. U.S. DC patients are more likely than GP only patients to be obese and to lack a regular doctor; Canadian DC patients are more likely than GP only patients to be college educated, to have higher incomes, and dissatisfied with MD care. Compared with seekers of both GP and DC care, DC only patients in both countries have fewer chronic conditions, take fewer drugs, and have no regular doctor. U.S. DC only patients are more likely than GP+DC patients to be uninsured and dissatisfied with health care; Canadian DC only patients are more likely than GP+DC patients to be under 45, male, less educated, smokers, and not obese, without disabling back or neck pain, on fewer drugs, and lacking a regular doctor. Conclusion Chiropractic and GP patients are dissimilar in both Canada and the U.S., with key differences between countries and between DC patients who do and do not seek care from GPs. Such variation has broad and potentially far-reaching health policy and

    The objective of this research was to use data from multiple studies to comprehensively quantify the effects of feeding 1) laidlomycin propionate (LP), alone and/or in combination with chlortetracycline, compared with 2) monensin sodium (MS), alone and/or in combination with tylosin, at commercially approved dosages, on ADG, DMI, feed efficiency (FE), mortality, and carcass characteristics (HCW and liver abscesses). A secondary objective was to explore potential sources of heterogeneity among the comparative effectiveness studies. A systematic review of peer-reviewed literature and industry reports was used to identify studies that included direct comparisons of these treatments in finishing steers in North America. Random-effects meta-analysis models of performance, carcass, and health-related outcomes were fitted with extracted data, consisting of a total of 17 data sets comprising a total of 135 pens and 13,603 steers. Results showed that pens of steers fed LP had increased ADG (live and carcass adjusted), DMI, and HCW compared with those fed monensin ( 0.05) were identified for FE or for health-related outcomes (overall and cause-specific mortality). There was a substantial amount of heterogeneity in outcomes among studies, and when pen size and type of production setting were included in mixed-effects meta-regression models, they accounted for only a small proportion of the between-study heterogeneity found in the meta-analysis models. Therefore, caution should be exercised when interpreting summary estimates in the presence of substantial heterogeneity. However, these results provide comprehensive information on the comparative effects of different ionophores across multiple studies and multiple years, states, and production settings. These unique results can enable quantitative and informed decisions by potential end users of these feed additives that are widely used in the U.S. beef industry for reducing the costs of beef production through enhanced cattle

    The voltammetry for the reduction of oxygen at a microdisc electrode is reported in two room temperature ionic liquids: 1-butyl-1-methylpyyrolidinium bis(trifluoromethylsulfonyl) imide ([Bmpyrr][NTf2]) and trihexyltetradecylphosphonium bis9trifluoromethylsulfonyl) imide ([P14,6,6,6][NTf2]) at 298 K. Simulated voltammograms using Butler-Volmer theory and Symmetric Marcus-Hush (SMH) theory were compared with experimental data. Butler-Volmer theory consistently provided experimental parameters with a higher level of certainty than SMH theory. A value of solvent reorganisation energy for oxygen reduction in ionic liquids was inferred for the first time as 0.4-0.5 eV, which is attributable to inner-sphere reorganisation with a negligible contribution from solvent reorganisation. The developed Butler-Volmer and Symmetric Marcus-Hush programs are also used to theoretically study the possibility of kinetically limited steady state currents, and to establish an approximate equivalence relationship between microdisc el...

    2016-07-01

    Haematopoietic cell transplants are done by more than 1500 transplant centres in 75 countries, mostly for life-threatening haematological disorders. However, transplant technology and access are not uniformly distributed worldwide. Most transplants are done predominately in Europe, North America and some Asian countries. We review transplant activity in Latin America, a geographic region with a population of >600 million persons living in countries with diverse economic and social development levels. These data indicate a 20-40-fold lower frequency of transplants in Latin America compared with Europe and North America. We show that although economics, infrastructure and expertise are important limitations, other variables also operate. Changes in several of these variables may substantially increase transplant activity in Latin America. PMID:26999468

    Some women receiving abnormal cervical screening tests do not complete recommended treatment. A prospective study (N = 660) investigated the value of conceptualizing attendance at colposcopy for treatment as either (a) an active problem-solving response to a health threat, motivated by attitudes toward an abnormal result, as implied by self-regulation theory (H. Leventhal, D. Meyer, & D. Nerenz, 1980); or (b) as a behavior motivated by attitudes toward clinic attendance, as implied by the theory of planned behavior (TPB; I. Ajzen, 1985). Responses to questionnaires containing variables specified by these models were used to predict women's subsequent attendance or nonattendance for treatment over the following 15 months. Although the TPB offered superior prediction of intentions and completion of treatment, discriminant function analyses showed that consideration of both models was important in distinguishing between those who attended all their appointments as scheduled, attended after being prompted, or ceased attending. Implications for measurement and theory in health protection are discussed. PMID:17014278

    2015-01-01

    Understanding and accurate prediction of gas or liquid phase (solute) diffusion are essential to accurate prediction of contaminant transport in partially saturated porous media. In this study, we propose analytical equations, using concepts from percolation theory and the Effective Medium Approximation (EMA) to model the saturation dependence of both gas and solute diffusion in porous media. The predictions of our theoretical approach agree well with the results of nine lattice Boltzmann simulations. We find that the universal quadratic scaling predicted by percolation theory, combined with the universal linear scaling predicted by the EMA, describes diffusion in porous media with both relatively broad and extremely narrow pore size distributions.

    2015-05-01

    Full Text Available The purpose of this paper is to compare probability theory with possibility theory, and to use this comparison in comparing probability theory with fuzzy set theory. The best way of comparing probabilistic and possibilistic conceptualizations of uncertainty is to examine the two theories from a broader perspective. Such a perspective is offered by evidence theory, within which probability theory and possibility theory are recognized as special branches. While the various characteristic of possibility theory within the broader framework of evidence theory are expounded in this paper, we need to introduce their probabilistic counterparts to facilitate our discussion.

  1. Pinta: Latin America's Forgotten Disease?

    Science.gov (United States)

    Stamm, Lola V

    2015-11-01

    Pinta is a neglected, chronic skin disease that was first described in the sixteenth century in Mexico. The World Health Organization lists 15 countries in Latin America where pinta was previously endemic. However, the current prevalence of pinta is unknown due to the lack of surveillance data. The etiological agent of pinta, Treponema carateum, cannot be distinguished morphologically or serologically from the not-yet-cultivable Treponema pallidum subspecies that cause venereal syphilis, yaws, and bejel. Although genomic sequencing has enabled the development of molecular techniques to differentiate the T. pallidum subspecies, comparable information is not available for T. carateum. Because of the influx of migrants and refugees from Latin America, U.S. physicians should consider pinta in the differential diagnosis of skin diseases in children and adolescents who come from areas where pinta was previously endemic and have a positive reaction in serological tests for syphilis. All stages of pinta are treatable with a single intramuscular injection of penicillin. PMID:26304920

  2. MOTIVATIONAL MEASURE OF THE INSTRUCTION COMPARED: Instruction Based on the ARCS Motivation Theory V.S. Traditional Instruction in Blended Courses

    Ozgur M. COLAKOGLU

    2010-04-01

    Full Text Available The ARCS Motivation Theory was proposed to guide instructional designers and teachers who develop their own instruction to integrate motivational design strategies into the instruction. There is a lack of literature supporting the idea that instruction for blended courses if designed based on the ARCS Motivation Theory provides different experiences for learners in terms of motivation than instruction developed following the standard instructional design procedure for blended courses. This study was conducted to compare the students’ motivational evaluation of blended course modules developed based on the ARCS Motivation Theory and students’ motivational evaluation of blended course modules developed following the standard instructional design procedure. Randomly assigned fifty junior undergraduate students studying at the department of Turkish Language and Literature participated in the study. Motivation Measure for the Blended Course Instruction (MMBCI instrument was used to collect data for the study after the Confirmatory Factor Analysis (CFA. Results of the study indicated that designing instruction in blended courses based on the ARCS Motivation Theory provides more motivational benefits for students and consequently contributes student learning.

  3. Comparative study of E⋯N (E = Se/Te) intramolecular interactions in organochalcogen compounds using density functional theory

    International Nuclear Information System (INIS)

    Highlights: • The nature and strength of E⋯N interaction in organochalcogen is investigated. • The E⋯N interaction (E = Se, Te) has a dominant covalent character. • Polar solvent favors the E⋯N interaction by shortening E-N distance. • Te⋯N interaction is found to be stronger than the corresponding Se⋯N interaction. - Abstract: The intramolecular E⋯N (E = Se, Te) interactions between the selenium (and tellurium) and the nitrogen atom in four series of o-substituted organochalcogen compounds have been analyzed using density functional theory. The nature and the strength of this interactions and their dependence on substituents and the rigidity are predicted using B3LYP/6-31G(d)/LanL2DZ method. The strength of these E⋯N interactions are found to be dependent on the nature of E-X (X = Cl, Br, I, SPh, CH2Ph; Ph: Phenyl) acceptor orbitals and follows the order I > Br > Cl > SPh > CH2Ph. The Natural Bond Orbital (NBO) analysis using DFT methods points to nN→σE−X* electron delocalization as the key contributing factor toward E⋯N nonbonding interactions. Both NBO and AIM methods suggest that the intramolecular interaction in these compounds is dominantly covalent in nature. Studies on the effect of solvent on the E⋯N interactions show that polar solvent stabilizes these interactions by shortening the E⋯N distances

    Full Text Available En América Latina durante el curso del siglo XX se lograron considerables avances para fortalecer los derechos de propiedad de la mujer casada. Sin embargo, se ha prestado atención limitada a los derechos de herencia de las esposas. La revisión de las normas legales en doce países permite argumentar que las viudas están a menudo en una posición de desventaja en comparación con las hijas/os de la pareja. Las normas sobre herencia no fueron diseñadas para dar a las viudas la posibilidad de autonomía económica, por medio del control de la finca familiar o los negocios. Si se tiene en cuenta la diferencia de género a favor de la mujer en la expectativa de vida y la cobertura limitada de las mujeres en la seguridad social (especialmente las rurales en la mayoría de los países, las mujeres son particularmente vulnerables cuando enviudan. Es urgente que el movimiento de mujeres tenga en cuenta en su agenda el tema de los derechos de herencia, en razón de que su fortalecimiento es necesario para el logro de la redistribución de la propiedad y de una al igualdad de géneroConsiderable gains were made in Latin America over the course of the twentieth century in strengthening the property rights of married women. Insufficient attention, nonetheless, has been given to the inheritance rights of wives. Reviewing the legal norms for twelve countries, it is argued that widows are often in a disadvantaged position compared to the children of a couple. Inheritance norms were not designed to give widows the possibility for economic autonomy, such as through control of the family farm or business. Moreover, given the gender gap favoring women in the lengthening of life spans and the low coverage of social security (particularly in rural areas in most countries, they are particularly vulnerable when they are widowed. The women's movement is urged to take on the issue of inheritance rights since strengthening these are necessary to achieve a

    During the last 4 billion years, the Earth's climate has changed many times. There have been periods of warming and there have been ice ages. These large-scale climatic changes are shaped by factors like the tilt of the Earth's axis and tectonic plate movement. These major changes were driven by cyclical changes in the Earth's orbit, which altered the distribution of solar energy between the seasons and across the Earth. Milankovitch cycles explain well changes in climate over periods hundreds of thousands of years and are related to ice age cycles, but these cycles cannot explain the current rapid warming. The Sun is the most driving force for causing climate change. Much of the Sun energy evaporates water and causes atmospheric convection. Solar radiation, general circulation of atmosphere, geographical location of continents, oceans and the largest forms of a relief are the primary factors influencing on climate of lands. The purpose of this study is to identify contribution of the Sun on climate variability in the two continents, North and South America during instrumental records of air temperature. There were compared air temperatures of different weather stations in dependence from solar activity during the period 1878-1996. The high correlation between averaged temperature and solar activity was found for many weather stations of Americas. Air temperature in dependence from solar activity over the period 1878-1996 can be described by following equations: In Buenos Aires: T° = 0,04W+ 15,05, r-0,9; Caracas, Venezuela: T° = 0,03W + 18,88, r-0,73; Cordoba, Argentina: T° = 0,03W + 16,16, r-0,93; New York, Central Park: T° = 0,04W + 9,86, r-0,82; Toronto, T = 0,03W+ 6,66, r-0,81; Santiago Pudahuel, T= 0,019W + 13, 01, r - 0, 91; Rio de Janeiro:T°= 0,02W + 21,95, r= 0,88; Mexico over 1923-1986, T°= 0,021W+ 14,05, r-0,78; Miami over 1902-1996, T = 0,012W + 12,87 r-0,75; In our study, we used stations with reasonably long, consistently measured time records

    This paper will present the procedure of measuring the deformation of the magnetostrictive bimorph specimens under an applied external magnetic field, and the theoretical and numerical analysis of the deformation. The magnetically smart material (MSM) KelvinAllTM and Terfenol-D is deposited on the nickel or glass substrates. The profiles of thin-film specimens were measured under an external magnetic field with White Light Interferometry. Using the theoretical calculation, the magnetostrictive property was evaluated for the coated Ni sample and glass sample. Employing the numerical approach, the influence of the magnetostrictive film on the deformation of the sample was simulated and compared with experimental results. The coated Ni specimen exhibited larger deformation than the coated glass specimen when the specimen is immersed in a 0.16 T magnetic field. In our experiments, the residual stress calculated in the thin film of the bimorph is acceptable and could be decreased by changing the parameters in the specimen preparation process. The experimental results in this paper was employed as the preliminary step to realize the future application of the magnetostrictive thin film bimorph to the adaptive X-ray mirror, and the theoretical and numerical approach was used to predict the influence of the magnetostrictive film on the larger mirror surface deformation.

    The human brain exhibits marked hemispheric differences, though it is not fully understood to what extent lateralization of the epileptic focus is relevant. Preoperative [18F]FDG-PET depicts lateralization of seizure focus in patients with temporal lobe epilepsy and reveals dysfunctional metabolic brain connectivity. The aim of the present study was to compare metabolic connectivity, inferred from inter-regional [18F]FDG PET uptake correlations, in right-sided (RTLE; n = 30) and left-sided TLE (LTLE; n = 32) with healthy controls (HC; n = 31) using graph theory based network analysis. Comparing LTLE and RTLE and patient groups separately to HC, we observed higher lobar connectivity weights in RTLE compared to LTLE for connections of the temporal and the parietal lobe of the contralateral hemisphere (CH). Moreover, especially in RTLE compared to LTLE higher local efficiency were found in the temporal cortices and other brain regions of the CH. The results of this investigation implicate altered metabolic networks in patients with TLE specific to the lateralization of seizure focus, and describe compensatory mechanisms especially in the CH of patients with RTLE. We propose that graph theoretical analysis of metabolic connectivity using [18F]FDG-PET offers an important additional modality to explore brain networks. PMID:27349503

  17. New views on American colonization: critical tests from South America

    Directory of Open Access Journals (Sweden)

    O'Rourke, Dennis

    2007-01-01

    Full Text Available The traditional view of colonization of the Americas as a migration across Beringia and subsequent dispersal southward following the last glacial maximum is being increasingly questioned. In North America, archaeological links to Siberia are tenuous and genetic data are more consistent with an earlier entry of people into the Americas, from Central rather than Northeast Siberia. An entry of populations into the Americas prior to the last glacial maximum forces a reconsideration not only of timing, but also geographic points of entry and speed of dispersal, based on ecological theory. A number of emerging alternative hypotheses on the colonization of the Americas predict early entry and dispersal of people into South America - earlier than, or coeval with, initial dispersal in North America. The study of genetic, morphological, and archaeological variation across South America is critical to testing these new, alternative hypotheses of Native American origins. I will review the evidence for emerging, alternative views of American Colonization, and suggest ways in which data from South American populations and prehistory will be crucial in testing them.

  12. A comparative study of smart passive piezoelectric structures interacting with electric networks: Timoshenko beam theory versus finite element plane stress calculations

    International Nuclear Information System (INIS)

    The present paper is devoted to the coupling between mechanical, piezoelectric and electric fields in piezoelastic beams whose electrodes are connected by electric circuits with arbitrary impedances. Taking advantage of the linear piezoelectric constitutive relations, the kinematic assumptions according to Timoshenko, the Gauss law of electrostatics as well as Kirchhoff's voltage rule, the equations of motion for lateral vibrations are derived in the Laplace domain considering the direct and converse piezoelectric effects. For beams with layerwise constant width, the governing equations are similar to the well-known Timoshenko beam equations, but the bending moment is extended by a so-called induced electric moment, which is influenced by the electric circuits. In order to demonstrate the interaction of mechanical and electrical fields, the theory that we develop is compared against plane stress finite element computations using ANSYS. For flexural vibrations with various mechanical boundary conditions and electric impedances, an eigenfrequency analysis is performed and mechanical and electrical field variables are compared for different harmonic excitations

We present in detail issues particularly relevant to prospective physicians, which are discussed with the main focus on the “theoretical and practical orientation of medical education”.Methods: We used the database in the Public Use File of the “11 Student Survey”, a written survey of randomly selected students studying at 25 German tertiary institutions during the 2009/2010 winter term, which was supplied by the Tertiary Education Research working group at the University of Constance. Data on 7536 students was included, of which 488 (6.5% were prospective physicians.Results: Human medicine students have a clear career aim and want to complete their education quickly. They have a far above-average interest in working with and for people. About one student in two is interested in a career in science or research (53% in each case – close to the average for all subjects. Compared with the other disciplines, HM students are most likely to consider their university education to have practical and research relevance and are most likely to feel prepared for their profession. Yet over half of all students (Ø 53.3%; HM 54.5% do not consider their education to have fostered their research skills. MINT students in particular are better able to enhance their skills through independent experimentation, while theory and practice are more likely to be communicated academically in the regular teaching of human medicine. Accordingly, the HM students feel less well supported in some areas of competence required for their later work than

    Time and its measurement belong to the most fundamental core of physics, and many scientific and technological advances are directly or indirectly related to time measurements. Timekeeping is essential to everyday life, and thus is the most measured physical quantity in modern societies. Time can also be measured with less uncertainty and more resolution than any other physical quantity. The measurement of time is of the utmost importance for many applications, including: global navigation satellite systems, communications networks, electric power generation, astronomy, electronic commerce, and national defense and security. This paper discusses how time is kept, coordinated, and disseminated in the Americas.

  5. Analysis of Long-Term Precipitation Sequencing Pattern Changes in North America

    Science.gov (United States)

    Roque, S.; Kumar, P.

    2015-12-01

    This study evaluates changes in long-term precipitation patterns in North America, focusing specifically on precipitation sequencing. Previous precipitation studies have explored changes in extreme precipitation events, intensity, and distribution, but sequencing changes and their effects are still largely not understood. Precipitation sequencing, or the overall temporal pattern of precipitation events, is a vital yet often overlooked part of developing long-term climate predictions; the assumption of long-term stationarity in climate variability, which suggests that past observed temporal patterns are likely to continue and can therefore be projected, weakens the robustness of climate models. Additionally, changes in sequencing could be a driver for fluctuations in the highly interconnected hydrologic cycle, meaning that tipping points and critical changes in the cycle could be better anticipated given a more complete picture of long-term temporal patterns. Analysis was based on precipitation data collected by the National Climatic Data Center for approximately 9000 stations in North America. Temporal patterns recorded at each station - the sequence of consecutive days with or without rain and the lengths of those increments - were reviewed and compared on a decadal and seasonal scale. Comparisons to date indicate that long-term precipitation patterns are non-stationary and therefore cannot be relied upon for long-term climate projections. It remains to be seen how exactly regional temporal patterns have fluctuated over time in North America, and results could provide interesting insight into observed hydrologic changes or serve to reinforce existing theories regarding regional hydrologic studies.

  6. The Regulation of Biosimilars in Latin America.

    2016-03-01

    This article summarizes the regulatory scenario on biological medications in Latin America focusing on comparability studies, extrapolation of indications, interchangeability and pharmacovigilance issues. In the case of comparability studies, what is being discussed is the possibility of decreasing the clinical trials requirement, but that the molecule should be well characterized in the studies of pharmacokinetics and pharmacodynamics. With the worldwide-level approval of the first monoclonal antibody biosimilar, infliximab, extrapolation of indications are being discussed, since the behavior of the Latin America regulatory agencies has been different with regard to such issue. Another issue discussed by the regulatory agencies is the interchangeability between biological medications and their biosimilars, mainly due to the fact that there is a clear confusion on interchangeability and substitution concepts. Finally, the pharmacovigilance debate, according to what takes place globally, is related to the need for identifying and differentiating the reference biological medication and its biosimilars for traceability purposes.

    Science.gov (United States)

    2003-01-01

    This anaglyph (stereoscopic view) of South America was generated with data from the Shuttle Radar Topography Mission (SRTM). It is best viewed at or near full resolution with anaglyph glasses. For this broad view the resolution of the data was first reduced to 30 arcseconds (about 928 meters north-south but variable east-west), matching the best previously existing global digital topographic data set called GTOPO30. The data were then resampled to a Mercator projection with approximately square pixels (about one kilometer, or 0.6 miles, on each side). Even at this decreased resolution the variety of landforms comprising the South American continent is readily apparent.Topographic relief in South America is dominated by the Andes Mountains, which extend all along the Pacific Coast. These mountains are created primarily by the convergence of the Nazca and South American tectonic plates. The Nazca Plate, which underlies the eastern Pacific Ocean, slides under western South America resulting in crustal thickening, uplift, and volcanism. Another zone of plate convergence occurs along the northwestern coast of South America where the Caribbean Plate also slides under the South American Plate and forms the northeastern extension of the Andes Mountains.East of the Andes, much of northern South America drains into the Amazon River, the world's largest river in terms of both watershed area and flow volume. Topographic relief is very low in much of the Amazon Basin but SRTM data provide an excellent detailed look at the basin's three-dimensional drainage pattern, including the geologic structural trough (syncline) that hosts the eastern river channel.North of the Amazon, the Guiana Highlands commonly stand in sharp contrast to the surrounding lowlands, indeed hosting the world's tallest waterfall, Angel Falls (979 meters or 3212 feet). Folded and fractured bedrock structures are distinctive in the topographic pattern.South of the Amazon, the Brazilian Highlands show a mix of

Theories with empirical supports include strain theory, learning theory, rational choice theory, and corporate structure theory. These theories approach corporate crime from different angles, so each has its own strengths. Strain theory emphasizes the relationship between corporate performance and crime, while learning theory concerns more about corporate culture and top management; on the other hand, rational choice theory, which is based on economic analysis, takes the cost-benefit analysis of corporate decision as the origin of corporate crime, meanwhile corporate structure theory is on quite the contrast, identifying the corporate governance as the source of corporate crime. As far as the relationship between corporate crime and corporate features, including corporate performance, size, top management backgrounds, the strength of these theories varies. Therefore, in order to improve corporate governance, a general explanatory theory

    International Nuclear Information System (INIS)

    The demand for uranium to be used in the world's nuclear power stations is barely increasing, but the supply is rocketing up. Much of it is coming from the countries of the former Soviet Union and some of it is so cheap that republics such as Russia, the Ukraine and Kazakhstan are being accused of dumping it. The strain is being felt in the uranium-producing countries of southern Africa, Australia and North America. Companies involved in various stages of the nuclear fuel cycle claim that unfairly priced imports form the former Soviet Union are damaging them and they have been busily lobbying authorities in the US and Europe for weeks. US uranium-producing firms, backed by the country's Oil, Chemical and Atomic Worker's Union, have asked the Department of Commerce to impose anti-dumping duties on deliveries of uranium and enriched uranium from the former Soviet republics to the US.

  18. Fermilab and Latin America

    International Nuclear Information System (INIS)

    As Director of Fermilab, starting in 1979, I began a series of meetings with scientists in Latin America. The motivation was to stir collaboration in the field of high energy particle physics, the central focus of Fermilab. In the next 13 years, these Pan American Symposia stirred much discussion of the use of modern physics, created several groups to do collaborative research at Fermilab, and often centralized facilities and, today, still provides the possibility for much more productive North-South collaboration in research and education. In 1992, I handed these activities over to the AAAS, as President. This would, I hoped, broaden areas of collaboration. Such collaboration is unfortunately very sensitive to political events. In a rational world, it would be the rewards, cultural and economic, of collaboration that would modulate political relations. We are not there yet

  19. A Comparative study of the theory of dual reality from the perspective of Averroes, followers of Averroes and the church of the thirteenth century

    Directory of Open Access Journals (Sweden)

    Ali Ghorbani

    2015-03-01

    Full Text Available In the thirteenth century, along with the return of the European thinkers and philosophers to Aristotelian philosophy and the emergence of the contradiction between Aristotle's philosophy and Christian teachings and religious beliefs, the church put forward a theory known as dual reality. According to this theory everything that is true in theology, its opposite can also be true in philosophy. With this theory, the church accused the philosophers of heresy, while the followers of Averroes considered themselves free of this charge. In his book Faṣl al-maqāl, Averroes appeared to be in favor of the above mentioned theory in a different form. By a precise analysis of the theory through reviewing the now available sources and considering the events followed by attributing this view to the philosophers, one can infer different implications from the theory from the perspective of each of the three sides involved (i.e. Averroes, followers of Averroes and church and the following division can be sketched: 1- ontological implications: that is to believe in the existence of two types of realities in the universe which can be described in two ways: A two contradictory scopes in the universe B two distinct scopes in the universe. 2- Epistemological implications of the dual reality: A Two ways to reach one reality. B Two dictions to narrate one reality. C Duality of the reality in practice. D Two levels of one single reality. By analyzing each of these implications of the dual reality, one can be led to some consequences according to which based on different works of Averroes he cannot be accused of believing in a kind of duality which makes him deserve heresy.

    Frame theory provides a new perspective for semantic research.Linguistic information and lexical meaning can evoke a frame and the construction of the frame is conducive to raising our understanding of linguistic expressions.Based on frame theory,this article focuses on linguistic expressions on the theme of values of freedom and democracy in American presidential inaugural speeches after World WarⅡ.It is found that American presidents frame American government as a hero and construct the moral framing of promoting values of freedom and democracy as a battle between "good and evil" by the use of some specific lexical items.%框架理论是一个语义研究的新视角,语言信息和词汇语义可以唤起框架;框架的构建有助于我们对语言表达的理解。本文从框架理论视角分析二战后美国总统就职演说中自由民主主题下的语言表达,发现美国总统使用一些特定语言词汇成功构建一个"英雄"框架来塑造美国的"英雄"形象,并把美国推广自由民主价值观的行为框定为"正义"与"邪恶"之战。

  7. Geoparks in Latin America

    International Nuclear Information System (INIS)

    A Geopark is a territory delimited part of a holistic concept of protection, education and sustainable development, based on geological sites of particular importance, rarity or aesthetic geological sites. A Geopark achieves its goals through three main areas: geoconservation, education and geotourism. The first network of Geoparks born in Europe in 2000, and from 2004 UNESCO is promoting the creation of a Global Geoparks Network (Global Geoparks Network, GGN ). Currently, there are 64 Global Geoparks in 19 countries, and the movement is in full development. In Latin America there is hardly Araripe Geopark in Brazil. Presented in this work, projects and studies related to the development of Geoparks in Argentina, Brazil, Chile, Costa Rica, Peru and Venezuela. We understand that Colombia, Cuba, Ecuador, Mexico and Nicaragua have projects in this line, but the details are not yet readily available. The authors invite geoscientists and professionals in related fields to join a movement for the creation of the Latin American Network of Geoparks, intended as a framework for the conservation, sustainable use and disclosure of our national geological heritage

  8. Wind Powering America

    International Nuclear Information System (INIS)

    At the June 1999 Windpower Conference, the Secretary of Energy launched the Office of Energy Efficiency and Renewable Energy's Wind Powering America (WPA) initiative. The goals of the initiative are to meet 5% of the nation's energy needs with wind energy by 2020 (i.e., 80,000 megawatts installed), to double the number of states that have more than 20 megawatts (MW) of wind capacity to 16 by 2005 and triple it to 24 by 2010, and to increase wind's contribution to Federal electricity use to 5% by 2010. To achieve the Federal government's goal, DOE would take the leadership position and work with its Federal partners. Subsequently, the Secretary accelerated the DOE 5% commitment to 2005. Achieving the 80,000 MW goal would result in approximately$60 billion investment and$1.5 billion of economic development in our rural areas (where the wind resources are the greatest). The purpose of this paper is to provide an update on DOE's strategy for achieving its goals and the activities it has undertaken since the initiative was announced

  15. Solvent dependence of Stokes shift for organic solute-solvent systems: A comparative study by spectroscopy and reference interaction-site model-self-consistent-field theory

    Science.gov (United States)

    2013-09-01

    The Stokes shift magnitudes for coumarin 153 (C153) in 13 organic solvents with various polarities have been determined by means of steady-state spectroscopy and reference interaction-site model-self-consistent-field (RISM-SCF) theory. RISM-SCF calculations have reproduced experimental results fairly well, including individual solvent characteristics. It is empirically known that in some solvents, larger Stokes shift magnitudes are detected than anticipated on the basis of the solvent relative permittivity, ɛr. In practice, 1,4-dioxane (ɛr = 2.21) provides almost identical Stokes shift magnitudes to that of tetrahydrofuran (THF, ɛr = 7.58), for C153 and other typical organic solutes. In this work, RISM-SCF theory has been used to estimate the energetics of C153-solvent systems involved in the absorption and fluorescence processes. The Stokes shift magnitudes estimated by RISM-SCF theory are ˜5 kJ mol-1 (400 cm-1) less than those determined by spectroscopy; however, the results obtained are still adequate for dipole moment comparisons, in a qualitative sense. We have also calculated the solute-solvent site-site radial distributions by this theory. It is shown that solvation structures with respect to the C-O-C framework, which is common to dioxane and THF, in the near vicinity (˜0.4 nm) of specific solute sites can largely account for their similar Stokes shift magnitudes. In previous works, such solute-solvent short-range interactions have been explained in terms of the higher-order multipole moments of the solvents. Our present study shows that along with the short-range interactions that contribute most significantly to the energetics, long-range electrostatic interactions are also important. Such long-range interactions are effective up to 2 nm from the solute site, as in the case of a typical polar solvent, acetonitrile.

  1. Social Pedagogy in North America: historical background and current developments

    Daniel Schugurensky

    2015-12-01

    Full Text Available In North America, the use of the term ‘social pedagogy’ is a relatively new phenomenon, but social pedagogical practices have been used for a long time. The recent interest in the field of social pedagogy can be explained in part by the publication of an unprecedented volume of books and articles in English language, the creation of a new international journal, the simultaneous development of graduate programs in social pedagogy in the UK and the USA, and the establishment of a social pedagogy association that brings together academics and practitioners. In North America, social pedagogy thinking is influenced by the history of the field, by current social pedagogy theory and practice in other parts of the world, and by several traditions that connect education with social change. The paper discusses ten of them: indigenous education, progressive education, social movement learning, community development, public pedagogy, popular education, participatory action research, social economy, participatory democracy, and critical theory

  2. Comparing the content of leadership theories and managers' shared perceptions of effective leadership: a Q-method study of trainee managers in the English NHS.

    2013-08-01

    Health service managers face potential conflicts between corporate and professional agendas, a tension sharpened for trainees by their junior status and relative inexperience. While academic leadership theory forms an integral part of contemporary management development programmes, relatively little is known of trainees' patterned subjectivities in relation to leadership theories. The objective of this study was to explore such subjectivities within a cohort of trainees on the National Health Service Graduate Management Training Scheme (NHS GMTS), a 'fast-track' programme which prepares graduate entrants for director-level health service management posts. A Q-method design was used and four shared subjectivities were identified: leadership as collaborative social process ('relational'); leadership as integrity ('moral'); leadership as effective support of subordinates ('team'); and leadership as construction of a credible leadership persona ('identity'). While the factors broadly map onto competencies indicated within the NHS Leadership Qualities Framework which underpin assessments of performance for this student group, it is important not to overstate the governance effect of the assessment regime. Rather, factors reflect tensions between required competencies, namely the mobilisation of diverse interest groups, the ethical base of decisions and the identity work required to convince others of leadership status. Indeed, factor 2 ('moral') effectively defines leadership as the embodiment of public service ethos. PMID:25595001

    Latin America`s incorporation into the international nuclear non-proliferation regime is well advanced. The 1967 Tlatelolco Treaty, which established a regional nuclear-weapon-free zone (NWFZ), is nearing completion. A signal event occurred January 18, when Argentina and Chile deposited instruments of ratification to the treaty, leaving Brazil and Cuba the only major countries in Latin America that are not yet contracting parties. And after more than two decades of concern about the nuclear programs and policies in Argentina and Brazil, there is room for great optimism that Brazil may now be moving quickly on important non-proliferation issues. Even Cuba, the {open_quotes}bad boy of the neighborhood{close_quotes} in the eyes of many, which held aloof from the Tlatelolco process for three decades, has stated its willingness to join the zone in the future.

    Full Text Available La investigación en torno a la violencia contra las mujeres en América Latina enfrenta una paradoja: el número de investigaciones es sumamente bajo, al mismo tiempo que existe una suerte de agotamiento del tema sin haberse dado aún respuestas definitivas sobre la naturaleza y las causas del problema. Ello responde a la orientación predominantemente empírica de las investigaciones, y a su falta de anclaje en la teoría sociológica más general. La investigación que se apoya en la teoría social suele ignorar las mediaciones existentes entre los arreglos estructurales y la conducta específica de los individuos, así como el carácter interaccional de la violencia. La investigación empírica, por su parte, presenta resultados inconsistentes y suele incurrir en problemas metodológicos tales como confusión operacional, y obviedad de los hallazgos y de las recomendaciones. Para enriquecer la investigación es indispensable diseñar nuevas investigaciones sustentadas en el corpus conceptual de las ciencias sociales y abandonar los diseños ateóricos y meramente estadísticos. Sólo así será posible imaginar las nuevas preguntas de investigación que requiere el problema de la violencia.Research on violence against women in Latin America presents an interesting paradox: while the number of studies is quite small, there also appears to be a sense that research on this topic has been exhausted, despite the lack of any definitive responses to the nature and causes of the problem. This results from the boom in studies with a strong empirical focus, lacking any basis in more general sociological theory. On the other hand, research using social theory tends to ignore the existing mediations between structural arrangements and any individual specific behavior, as well as the interactive nature of domestic violence. Meanwhile, empirical research presents inconsistent results and tends to run into methodological problems such as operational

    This anaglyph (stereoscopic view) of North America was generated with data from the Shuttle Radar Topography Mission (SRTM). It is best viewed at or near full resolution with anaglyph glasses. For this broad view the resolution of the data was first reduced to 30 arcseconds (about 928 meters north-south and 736 meters east-west in central North America), matching the best previously existing global digital topographic data set called GTOPO30. The data were then resampled to a Mercator projection with approximately square pixels (about one kilometer, or 0.6 miles, on each side). Even at this decreased resolution the variety of landforms comprising the North American continent is readily apparent.Active tectonics (structural deformation of the Earth's crust) along and near the Pacific North American plate boundary creates the great topographic relief seen along the Pacific coast. Earth's crustal plates converge in southern Mexico and in the northwest United States, melting the crust and producing volcanic cones. Along the California coast, the plates are sliding laterally past each other, producing a pattern of slices within the San Andreas fault system. And, where the plates are diverging, the crust appears torn apart as one huge tear along the Gulf of California (northwest Mexico), and as the several fractures comprising the Basin and Range province (in and around Nevada).Across the Great Plains, erosional patterns dominate, with stream channels surrounding and penetrating the remnants of older smooth slopes east of the Rocky Mountains. This same erosion process is exposing the bedrock structural patterns of the Black Hills in South Dakota and the Ozark Mountains in Arkansas. Lateral erosion and sediment deposition by the Mississippi River has produced the flatlands of the lower Mississippi Valley and the Mississippi Delta.To the north, evidence of the glaciers of the last ice age is widely found, particularly east of the Canadian Rocky Mountains and around the

    Grassi, A; Forte, G; Angilella, G G N; Pucci, R; March, N H

    2004-01-01

    The present study of small molecules containing silicon has been motivated by (a) the considerable interest being shown currently in the kinetics and reactivity of such molecules, and (b) the biotechnological potential of silicon-derivate surfaces as substrates in the adsorption of, for instance, amino acids and proteins. Therefore, we have studied by (i) a semi-empirical approach and (ii) an ab initio procedure employing low-order Moller-Plesset perturbation theory, the molecular correlation energies of some neutral closed and open shell silicon-containing molecules in the series SiXnYm. Procedure (i) is shown to have particular merit for the correlation of the ionic members studied in the above series, while the ab initio procedures employed come into their own for neutral species.

    Full Text Available This article explores the institutionalization of state-led development in Myanmar after 1988 in comparison with Suharto’s Indonesia. The analysis centres on the characteristics and theory of developmental states that emerged from the studies of East Asian countries like Japan, South Korea, and Taiwan. In Southeast Asia, Suharto’s Indonesia was perceived as a successful case and was studied by scholars in line with the characteristics of the developmental state. The Tatmadaw (military government in Myanmar was believed to follow the model of state-led development in Indonesia under Suharto where the military took the role of establishing economic and political development. However, Myanmar has yet to achieve its goal of building a successful state-led development. Therefore, this paper argues that implementing an efficient and effective institutionalization is essential for a successful state-led development (developmental state in Myanmar.

    Full Text Available The college transition represents a critical period for maintaining a healthy weight, yet intervention participation and retention represent significant challenges. The objective of this investigation was to evaluate the preliminary efficacy and acceptability of two interventions to prevent freshman weight gain. One intervention provided opportunities to improve outcome expectations and self-efficacy within a social cognitive theory framework (SCT, while the other targeted the same variables but focused on explicit training in self-regulation skills (SCTSR. Methods. Freshmen (n=45 aged >18 years were randomized to a 14-week intervention, SCT or SCTSR; both included online modules and in-class meetings. Of the 45 students randomized, 5 withdrew before the classes began and 39 completed pre- and posttesting.

    Full Text Available Mythological criticism is one of the main methods of contemporary literary criticism that has been based on findings of contemporary psychology and anthropology and history of civilisation, has been influenced particularly by the theories of Carl Gustav Jung, about the “collective unconscious” and “archetypes” that his psychology has been called analytic psychology, and his analytic method for mythology has been referred to as “Analytic Mythology.” In this paper, we observe the symbolism of fire in myths, with this approach. The opposition and the projection of formation of homeostasis between the elements is a result of psychological projection of collective unconscious contents on environmental subjects, in order to overcome on the nature. Meanwhile, there are the roles for the fire that it are observed in the world of mythology, including in the Ferdowsi’s Shahnameh and they are divided into two parts: First, in mythology, element of fire, as a higher element and the intermediate in between heaven and earth, is a symbol of the appearance of divine transfigure and eminence of a spiritual material in the world. Second, it is a symbol of heavenly power and object of the All-Powerful God’s torture (fire of hell, which this stage is a terrible and torrid shibboleth (the shibboleth of fire, that should be passed to a higher stage. Key words: mythological criticism, archetype, collective unconscious, Jung, Shahnameh, fire.

  20. Conservation and Development in Latin America and Southern Africa: Setting the Stage

    Directory of Open Access Journals (Sweden)

    2012-06-01

    Full Text Available The articles in this Special Feature stem from a 2010 conference (Bridging Conservation and Development in Latin America and Africa organized by the University of Florida's Tropical Conservation Development Program, Center for African Studies, and Center for Latin American Studies. The conference involved researchers and practitioners from Africa and Latin America focused on the complex and evolving relationship between conservation and development. The conference provided bridges between academics and non-academics, conservation and development, and theory and practice. The resulting comparative analyses focus on: empowerment of local institutions; enhanced capacity of local and regional stakeholders through a recognition and validation of local knowledge systems and the creation of knowledge networks; understanding of social and natural landscapes, history, contexts, and their evolution; and the roles of economic and market forces in shaping opportunities for using market-based incentives to promote conservation and development. In this introductory article we propose a conceptual framework based on the six connected pillars of natural resource characteristics, interactions of social actors, governance and participation, politics, information exchange, and economic issues that support spaces for both conflicts and synergies between conservation and development goals. Our goal is to foster informed dialogue and social learning to promote sustainability.

  19. A company I can trust? Organizational lay theories moderate stereotype threat for women.

    Science.gov (United States)

    Emerson, Katherine T U; Murphy, Mary C

    2015-02-01

    Women remain under-represented in the leadership of corporate America. According to stereotype threat theory, this under-representation may persist because women are concerned about being stereotyped in business settings. Three studies investigated whether an entity (fixed), compared with an incremental (malleable), organizational lay theory is threatening for women evaluating a consulting company. Men and women viewed a company mission statement or website containing an entity or incremental theory. Results revealed that women--more so than men--trusted the entity company less than the incremental company. Furthermore, only women's mistrust of the entity company was driven by their expectations about being stereotyped by its management. Notably, when combined with high or low representations of female employees, only organizational lay theories predicted trust. Finally, people's--particularly women's--mistrust of the entity company led them to disengage more before interacting with a representative. Implications for women's experiences and outcomes in workplace settings are discussed. PMID:25534242

    2009-05-01

    NOAM-SOIL is being created by combining the CONUS-SOIL database with pedon data and soil geographic data coverages from Canada and Mexico. Completion of the in-progress NOrth AMerica Soil (NOAM-SOIL) database will provide complete North America coverage comparable to CONUS. Canadian pedons, which number more than 500, have been painstakingly transcribed to a common format, from hardcopy, and key- entered. These data, along with map unit polygons from the 1:1,000,000 Soil Landscapes of Canada, will be used to create the required spatial data coverages. The Mexico data utilizes the INEGI 1:1,000,000 scale soil map that was digitized by U. S. Geological Survey EROS Data Center in the mid 1990's plus about 20,000 pedons. The pedon data were published on the reverse side of the paper 1:250,000 scale Soil Map of Mexico and key entered by USDA and georeferenced by Penn State to develop an attribute database that can be linked to the 1:1,000,000 scale Soil Map of Mexico based on taxonomic information and geographic proximity. The essential properties that will be included in the NOAM-SOIL data base are: layer thickness (depth to bedrock or reported soil depth); available water capacity; sand, silt, clay; rock fragment volume; and bulk density. For quality assurance purposes, Canadian and Mexican soil scientists will provide peer review of the work. The NOAM-SOIL project will provide a standard reference dataset of soil properties for use at 1km resolution by NACP modelers for all of North America. All data resources, including metadata and selected raw data, will be provided through the Penn State web site: Soil Information for Environmental Modeling and Ecosystem Management (www.soilinfo.psu.edu). Progress on database completion is reported.

  2. North America and Asia Pacific LNG markets

    International Nuclear Information System (INIS)

    The liquefied natural gas (LNG) export opportunities in the Asia Pacific market were reviewed. Some of the differences that affect a North American LNG projects compared to more typical LNG projects were also outlined. The two main aspects of the LNG market in North America include the establishment of LNG import terminals on the east and southern coasts of the United States and the development of export oriented LNG projects. The Pac-Rim LNG project calls for initial delivery to South Korea of 4.0 MTPA by the end of 2000. A large LNG project has also been proposed for the year 2005 which would use Prudhoe Bay gas. Generally, in North America, there is little use for large scale LNG import projects because of the vast pipeline network that delivers gas reliably and at low cost anywhere in North America. However, LNG remains a good alternative for the Asia Pacific region because of the lack of a pipeline network. Also, Japan, Korea and Taiwan, the three main centers for LNG demand, have no domestic energy supplies and rely on imported energy sources. China is another major market opportunity for LNG. The Pac-Rim LNG project differs from others of its kind in that usually, an LNG project is based on the availability of large reservoirs of natural gas owned by state governments and involves production agreements with multi-national oil and gas companies. This scenario is simply not possible in Canada's deregulated environment. In contrast, the existence of upstream facilities, technical expertise, and low capital costs, hence reduced risks and time to develop an LNG project, gives Canada significant advantages. 3 tabs., 3 figs

  8. Neo-newtonian theories

    CERN Document Server

    Fabris, J C

    2015-01-01

    General Relativity is the modern theory of gravitation. It has replaced the newtonian theory in the description of the gravitational phenomena. In spite of the remarkable success of the General Relativity Theory, the newtonian gravitational theory is still largely employed, since General Relativity, in most of the cases, just makes very small corrections to the newtonian predictions. Moreover, the newtonian theory is much simpler, technically and conceptually, when compared to the relativistic theory. In this text, we discuss the possibility of extending the traditional newtonian theory in order to incorporate typical relativistic effects, but keeping the simplicity of the newtonian framework. We denominate these extensions neo-newtonian theories. These theories are discussed mainly in the contexts of cosmology and compact astrophysical objects.

  9. Tlatelolco regime and nonproliferation in Latin America

    International Nuclear Information System (INIS)

    The regime established by the Treaty of Tlatelolco supports peace and security in the Latin American region and global nonproliferation efforts. Circumstances leading to the creation of the nuclear-weapon-free zone include careful preparations and negotiations, individual leadership, existence of certain shared cultural and legal traditions of Latin American countries, and the temporary stimulus of the Cuban missile crisis. The lack of overt superpower pressure on Latin America, compared with more turbulent regions, has permitted continued progress toward full realization of the zone. Tlatelolco's negotiating process, as well as the substance of the Treaty, deserve careful consideration relative to other areas. The Treaty enjoys wide international approval, but full support by certain Latin American States (Argentina, Brazil, Chile, Cuba) has been negatively affected by the failure of the US Senate to ratify Tlatelolco's Protocol I. Nuclear programs of Argentina, Brazil, and Mexico are expanding rapidly and these nations are forming linkages with West European countries, rather than the United States. The May 1980 Argentine-Brazilian nuclear agreement foresees significant cooperation between the two nation's nuclear energy commissions and more coordinated resistance to the nuclear supplier countries. Argentine-Brazilian nuclear convergence and the response accorded to it by the United States will have significant implications for the future of the Tlatelolco regime and nonproliferation in Latin America. 52 references

This paper aims at identifying the possible applications of these devices, as well as identifying obstacles to such utilities. Therefore, a two-part study was conducted: An expert Delphi study and a nationwide online survey in Germany and Austria. In this paper, the results of the online survey are reported and compared to the findings of the Delphi study. The questionnaire of the online survey was based on a theoretical framework comprising different dimensions for the use of MED. Overall, 120 projects were included in the study. The most common target groups were school classes and the devices most frequently used were GPS receivers. The projects addressed the criteria of ESD, such as elaboration of local/global perspectives of sustainability and competencies of EE like pro-environmental behavior or attitudes. All projects were classified according to their educational design in a 2 × 2-scheme. The most common activities were predefined routes within a narrow instructional setting. Divergences between expert views and practical realization are identified and discussed.

  11. Health outcomes among HIV-positive Latinos initiating antiretroviral therapy in North America versus Central and South America

    Full Text Available Introduction: Latinos living with HIV in the Americas share a common ethnic and cultural heritage. In North America, Latinos have a relatively high rate of new HIV infections but lower rates of engagement at all stages of the care continuum, whereas in Latin America antiretroviral therapy (ART services continue to expand to meet treatment needs. In this analysis, we compare HIV treatment outcomes between Latinos receiving ART in North America versus Latin America. Methods: HIV-positive adults initiating ART at Caribbean, Central and South America Network for HIV (CCASAnet sites were compared to Latino patients (based on country of origin or ethnic identity starting treatment at North American AIDS Cohort Collaboration on Research and Design (NA-ACCORD sites in the United States and Canada between 2000 and 2011. Cox proportional hazards models compared mortality, treatment interruption, antiretroviral regimen change, virologic failure and loss to follow-up between cohorts. Results: The study included 8400 CCASAnet and 2786 NA-ACCORD patients initiating ART. CCASAnet patients were younger (median 35 vs. 37 years, more likely to be female (27% vs. 20% and had lower nadir CD4 count (median 148 vs. 195 cells/µL, p<0.001 for all. In multivariable analyses, CCASAnet patients had a higher risk of mortality after ART initiation (adjusted hazard ratio (AHR 1.61; 95% confidence interval (CI: 1.32 to 1.96, particularly during the first year, but a lower hazard of treatment interruption (AHR: 0.46; 95% CI: 0.42 to 0.50, change to second-line ART (AHR: 0.56; 95% CI: 0.51 to 0.62 and virologic failure (AHR: 0.52; 95% CI: 0.48 to 0.57. Conclusions: HIV-positive Latinos initiating ART in Latin America have greater continuity of treatment but are at higher risk of death than Latinos in North America. Factors underlying these differences, such as HIV testing, linkage and access to care, warrant further investigation.

    The book represents the first, comprehensive attempt to take an empirical approach for comparative assessment of theories in sociology. The aims, problems, and advantages of the empirical approach are discussed in detail, and the three theories selected for the purpose of this work are explained. Their comparative assessment is performed within the framework of several research projects, which among other subjects also investigate the social aspects of the protest against nuclear power plants. The theories analysed in this context are the theory of mental incongruities and that of the benefit, and their efficiency in explaining protest behaviour is compared. (orig./HSCH)

    Ni, James

    2004-11-01

    Robert Kovach's second book looks at the interplay of earthquake and volcanic events, archeology, and history in the Americas. Throughout history, major earthquakes have caused the deaths of millions of people and have damaged countless cities. Earthquakes undoubtedly damaged prehistoric cities in the Americas, and evidence of these events could be preserved in archeological records. Kovach asks, Did indigenous native cultures-Indians of the Pacific Northwest, Aztecs, Mayas, and Incas-document their natural history? Some events have been explicitly documented, for example, in Mayan codices, but many may have been recorded as myth and legend. Kovach's discussions of how early cultures dealt with fearful events such as earthquakes and volcanic eruptions are colorful, informative, and entertaining, and include, for example, a depiction of how the Maya would talk to maize plants in their fields during earthquakes to reassure them.

    Full Text Available In contrast to the great time depth of Pleistocene rock art and mobiliary ‘art’ in the four other continents, the available evidence from the Americas is very limited, and restricted at best to the last part of the final Pleistocene. A review of what has so far become available is hampered by a considerable burden of literature presenting material contended to be of the Ice Age, even of the Mesozoic in some cases, that needs to be sifted through to find a minute number of credible claims. Even the timing of the first colonization of the Americas remains unresolved, and the lack of clear-cut substantiation of palaeoart finds predating about 12,000 years bp is conspicuous. There are vague hints of earlier human presence, rendering it likely that archaeology has failed to define its manifestations adequately, and Pleistocene palaeoart remains almost unexplored at this stage.

    Music is one of the most important and strongest types of cultural expression in South America. With diverse roots in the myriad of cultures of the many countries which shape our continent, music contributes to the South American identity. Distinct sounds, rhythms, styles and instruments compose a musical tissue, in which it is possible to recognize the special colors of a specific country or the printed image of the sonorous "language" from a special region.

  4. Presidential and Prime Ministerial Women in the Americas: A List with Interpretations

    Directory of Open Access Journals (Sweden)

    Rhodri Jeffreys-Jones

    2013-04-01

    Full Text Available The Americas and Latin America in particular are sharply in advance of the global norm when it comes to the incidence of female presidential and prime ministerial leadership. One reason is the relatively high and increasing incidence of democracy on the two continents. Another is that the Americas are more progressive than other parts of the world. The relatively peaceful state of the region over the last half century is an additional factor, for women favor peace and force works to their disadvantage. The theory that dynastic advantages account for the prominence of female leadership in the Americas is erroneous. United States has lacked female leadership because of a countervailing male culture that blocks women’s aspirations, and because the nation has been on a near-permanent war footing. In an appendix, the arguments are supported by a table listing the world’s “Women Prime Ministers and Presidents 1960-2010.”

  5. Natural gas in Latin America

    International Nuclear Information System (INIS)

    Despite having proven reserves equal to that of North America, natural gas has traditionally played a minor role in the energy policies of Latin American countries, being considered secondary to oil. There has, therefore, been a neglect of the sector with a resultant lack of an adequate infrastructure throughout the region, perhaps with the exception of Argentina. However, with a massive increase in energy demand, growing concerns with environmental matters and a need to reduce the massive pollution levels in major cities in the region, natural gas is forecast to play a much greater role in Latin America's energy profile, with final consumption forecast to rise at 5.4% per annum for the next 15 years. This book assesses both the development of the use of natural gas in the power industrial sector and proposals for its growth into the residential, commercial and transport sectors. It analyses the significant investment required and the governments' need to turn to the private sector for investment and innovation. Natural Gas in Latin America analyses the possibilities and pitfalls of investing in the sector and describes the key trends and issues. It analyses all aspects of the gas industry from exploration and production to transportation and distribution to end users. (Author)

    In December 2010, Peter Dreesen of CERN’s Technology Department (TE) returned from a long trip to South America. In four months he traversed the entire Andean range, from the equator to a latitude of 55 degrees south—on a bicycle!   Peter Dreesen on the Salar de Uyuni Lake, Bolivia. 11 000 kilometres is one long bike ride! And yet, that’s what Peter Dreesen did, travelling from Quito, Ecuador to Ushuaia, Argentina. Peter, an engineer in the TE Department, is no novice: the year before, he cycled from Paris to Peking, a distance of 13 500 kilometres, in just over four months. His latest voyage began last August, when he loaded his bicycle and boarded a plane for South America. In the saddle. After a week of acclimatisation at three thousand metres altitude, Peter left Quito on 6 August 2010. He arrived in Ushuaia (el fin del mundo, the end of the world, as it’s known in South America) on 12 December 2010. He recounts: “It was a bizarre sensation...

    Full Text Available As abordagens e expressões da questão social como pobreza envolvem discussões acerca da configuração e do enfrentamento de fraturas sociais, vinculadas ao processo de reestruturação produtiva capitalista, em diversas dimensões: econômicas, políticas, culturais e sociais. O objetivo do artigo é rever esse debate, passados 40 anos da teoria de marginalidade latino-americana, que inaugurou um olhar específico sobre a pobreza a partir da tese de massa marginal de Jose Nun. Ao longo desse período, são destacadas singularidades dos olhares sobre a pobreza como questão social na América Latina e a aproximação com os teóricos franceses da exclusão social. Após a década de 1990, observa-se o direcionamento do debate na perspectiva teórica da exclusão social, operacionalizada como uma categoria capaz de revelar processos de fragilização e ruptura da coesão social a partir de múltiplos níveis e dimensões relacionais.Approaches to, and expressions of, social issues as poverty involve discussing how social fractures connected with the process of capitalist restructuring are shaped and to be addressed in several dimensions (economic, political, cultural and social. This paper aims to review this debate 40 years after Jose Nun's marginality theory turned a fresh eye to Latin American poverty. It highlights singularities over that period in ways of looking at poverty as a social issue in Latin America and the approximation with French theorists of social exclusion. After the 1990's the debate is steered by the theoretical perspective of social exclusion, operationalised as a category capable of revealing the weakening and breakdown of social cohesion in terms of multiple levels and relational dimensions.

  10. Spin density distribution in open-shell transition metal systems: A comparative post-Hartree-Fock, Density Functional Theory and quantum Monte Carlo study of the CuCl2 molecule

    CERN Document Server

    Caffarel, Michel; Scemama, Anthony; Ramírez-Solís, Alejandro

    2014-01-01

    We present a comparative study of the spatial distribution of the spin density (SD) of the ground state of CuCl2 using Density Functional Theory (DFT), quantum Monte Carlo (QMC), and post-Hartree-Fock wavefunction theory (WFT). A number of studies have shown that an accurate description of the electronic structure of the lowest-lying states of this molecule is particularly challenging due to the interplay between the strong dynamical correlation effects in the 3d shell of the copper atom and the delocalization of the 3d hole over the chlorine atoms. It is shown here that qualitatively different results for SD are obtained from these various quantum-chemical approaches. At the DFT level, the spin density distribution is directly related to the amount of Hartree-Fock exchange introduced in hybrid functionals. At the QMC level, Fixed-node Diffusion Monte Carlo (FN-DMC) results for SD are strongly dependent on the nodal structure of the trial wavefunction employed (here, Hartree-Fock or Kohn-Sham with a particula...

    Blair, John E A; Huffman, Mark; Shah, Sanjiv J

    2013-05-01

    Heart failure is a major health problem that affects patients and healthcare systems worldwide. Within the continent of North America, differences in economic development, genetic susceptibility, cultural practices, and trends in risk factors and treatment all contribute to both inter-continental and within-continent differences in heart failure. The United States and Canada represent industrialized countries with similar culture, geography, and advanced economies and infrastructure. During the epidemiologic transition from rural to industrial in countries such as the United States and Canada, nutritional deficiencies and infectious diseases made way for degenerative diseases such as cardiovascular diseases, cancer, overweight/obesity, and diabetes. This in turn has resulted in an increase in heart failure incidence in these countries, especially as overall life expectancy increases. Mexico, on the other hand, has a less developed economy and infrastructure, and has a wide distribution in the level of urbanization as it becomes more industrialized. Mexico is under a period of epidemiologic transition and the etiology and incidence of heart failure is rapidly changing. Ethnic differences within the populations of the United States and Canada highlight the changing demographics of each country as well as potential disparities in heart failure care. Heart failure with preserved ejection fraction makes up approximately half of all hospital admissions throughout North America; however, important differences in demographics and etiology exist between countries. Similarly, acute heart failure etiology, severity, and management differ between countries in North America. The overall economic burden of heart failure continues to be large and growing worldwide, with each country managing this burden differently. Understanding the inter-and within-continental differences may help improve understanding of the heart failure epidemic, and may aid healthcare systems in delivering

    Two photolineation maps of southwestern Guatemala and Chiapas were made from S190 photographs along a ground track from Acajutla, El Salvador to San Cristobal de las Casas, Mexico. The maps document a structural complexity spanning the presumed triple junction of the Cocos, Americas, and Caribbean plates. The Polochic fault zone, supposedly the Americas-Caribbean plate boundary, is a sharply delineated feature across western Guatemala. Westward of the Mexican border it splays into a large number of faults with NW to SW trends. The structural pattern is quite different to the north (Americas plate) and to the south (Caribbean plate) of the Polochic fault, though both areas are dominated by NW-trending lineations. Within the Central American volcanic chain, the lineation patterns support the segmented model of the Benioff Zone, by showing a concentration of transverse lineations in the predicted locations, most notably NE-trending elements near Quezaltenango, Guatemala. The structural pattern obtained from the maps are compared to patterns described on recently published maps of more southerly parts of Central America, to begin a synthesis of the structure of the convergent plate boundary.

    We explore the bias in monthly and seasonal mean precipitation simulated by ensembles of different regional climate models over South America within the context of the EU-FP6 CLARIS project (A Europe-South America Network for Climate Change Assessment and Impact Studies). We briefly described two series of coordinated simulations: (i) Case studies of anomalous months for south-eastern South America performed with an ensemble of six models, and (ii) A multiyear simulation of the period 1991-2000 performed by four models. The models have been forced with the European Centre for Medium Range Weather Forecasting Reanalysis (ERA-40) and are compared to observational data compiled by the Climatic Research Unit (CRU). The ensemble-mean bias can be large when simulating particular extreme periods in La Plata Basin. Our multi-model analysis suggests that even though the ten-year ensemble mean is able to capture the major regional characteristics of seasonal mean precipitation for South America, models individually display considerable precipitation biases especially in tropical areas. The relatively good performance of the multi-model annual average over La Plata Basin results from the cancelation of offsetting errors in the individual models. (orig.)

  1. Nutritional situation in the Americas.

    Science.gov (United States)

    1994-09-01

    PAHO member countries maintain food and nutrition surveillance systems. The prevalence of malnutrition among children aged 0-4 in Latin American and Caribbean countries ranges from 0.8% in Chile to 38.5% in Guatemala. It is 2.9% in the US. Low height-for-age is most common among children aged 0-4 in Guatemala (57.9%), Bolivia (38.3%), Peru (35.2%), and Ecuador (34%). The interval between observations of malnutrition prevalence ranged from 22 years in Honduras to 3-4 years in Nicaragua and Panama. Overall, there was a downward trend in malnutrition rates in the Americas. Yet, malnutrition is increasing in Guatemala and Panama. Breast feeding, good weaning practices, appropriate feeding during disease episodes, nutrition education, and programs for immunization and control of diarrhea and respiratory diseases account for the downward trend. Anemia rates among pregnant women (=or 11 g Hb/dl) vary from 13% in Asuncion, Paraguay, to 61% in Misiones, Argentina. Those for preschoolers range from 22% to 45% in Brazil and 27% to 53% in Peru. The prevalence of goiter is more than 50% in Merida, Venezuela, and Chameza, Colombia. It differs greatly in different areas within the same country. Most countries have laws requiring iodination of all salt for human consumption, yet violations are common. Certain areas of the countries in the Americas have vitamin A deficiency rates ranging from 5% to 48.8%. Some countries have enacted laws for sugar enrichment with retinol palmitate to reduce vitamin A deficiency. During the 1970s, deaths from chronic diseases related to nutrition increased 105% in South America, 56% in Central America, Mexico, and Panama, and 21% in the Caribbean. Prevalence of obesity among children aged 0-6 varies from 2.2% in Nicaragua and Brazil to 10.7% in Chile. Adult obesity is most common in Uruguay (about 50%). It is more common among females than males. The highest rates among 20-29 year olds are in Chile, Costa Rica, Cuba, and Peru. The US adult obesity

  2. HEAVY ION FUSION SCIENCE VIRTUAL NATIONAL LABORATORY 2nd QUARTER 2010 MILESTONE REPORT. Develop the theory connecting pyrometer and streak camera spectrometer data to the material properties of beam heated targets and compare to the data

    International Nuclear Information System (INIS)

    This milestone has been accomplished. We have extended the theory that connects pyrometer and streak spectrometer data to material temperature on several fronts and have compared theory to NDCX-I experiments. For the case of NDCX-I, the data suggests that as the metallic foils are heated they break into droplets (cf. HIFS VNL Milestone Report FY 2009 Q4). Evaporation of the metallic surface will occur, but optical emission should be directly observable from the solid or liquid surface of the foil or from droplets. However, the emissivity of hot material may be changed from the cold material and interference effects will alter the spectrum emitted from small droplets. These effects have been incorporated into a theory of emission from droplets. We have measured emission using streaked spectrometry and together with theory of emission from heated droplets have inferred the temperature of a gold foil heated by the NDCX-I experiment. The intensity measured by the spectrometer is proportional to the emissivity times the blackbody intensity at the temperature of the foil or droplets. Traditionally, a functional form for the emissivity as a function of wavelength (such as a quadratic) is assumed and the three unknown emissivity parameters (for the case of a quadratic) and the temperature are obtained by minimizing the deviations from the fit. In the case of the NDCX-I experiment, two minima were obtained: at 7200 K and 2400 K. The best fit was at 7200 K. However, when the actual measured emissivity of gold was used and when the theoretical corrections for droplet interference effects were made for emission from droplets having radii in the range 0.2 to 2.0 microns, the corrected emissivity was consistent with the 2400 K value, whereas the fit emissivity at 7200 K shows no similarity to the corrected emissivity curves. Further, an estimate of the temperature obtained from beam heating is consistent with the lower value. This exercise proved to be a warning to be skeptical

  3. Lianas as invasive species in North America: Chapter 28

    Science.gov (United States)

    Leicht-Young, Stacey A.; Pavlovic, Noel B.

    2015-01-01

    Liana diversity is typically low in the temperate zones; however, the influx of non-native invasive liana species in North America has increased local diversity at the expense of native habitats and species. Some of the most illustrative studies of invasive lianas in temperate North America compared the biological traits of invasive lianas with native congeners or ecological analogs. The majority of these studies focused on two species, Celastrus orbiculatus (oriental bittersweet) and Lonicera japonica (Japanese honeysuckle). Temperate zone lianas generally have higher photosynthetic rates than other early successional species and their host trees. Invasive lianas are having an increasing impact on the dynamics and trajectories of North American plant communities. They often exhibit superior growth and survival compared to their native counterparts, and in some cases, invasive lianas may directly contribute to the decline of their native correlates.

    In this paper the economic performance of post-independence Latin America is assessed in comparative perspective. The release from the colonial fiscal burden was partly offset by higher costs of self-government, while the opening of independent Latin American countries to the international economy represented a handmaiden of growth. Regional disparities increased after independence, so generalisations about the region's long-run behaviour are not straightforward. However, on average, per capi...

    2001-01-01

    Pesticides are an extensively documented occupational and environmental hazard in Central America. Yet, severe problems persist. Toxic pesticide use in the Region increased during 1985-1999. High exposure levels and ineffectiveness of personal protective equipment evidence the difficulties for risk reduction. Acute poisonings remain a severe problem. Delayed and/or long-lasting health effects include dermatoses, cancer, and genotoxic, neurotoxic, and respiratory effects. The use of hazardous pesticides persists through deficiencies in government-driven assessment and risk management; excessive focus on regional harmonization; short-term economic interests; strong links between industry and governments; aggressive marketing; weak trade unions; and failure of universities to reach decision makers. Regulation based on local data is lacking. An agreement of the Ministries of Health for restricting the most toxic pesticides in Central America has potential for progress. The most effective way to reduce risk is to greatly reduce pesticide use. Actions needed include development of multidisciplinary strategies for local studies on health and environmental impact of pesticides; development of sustainable nonchemical agricultural technologies; evaluation of interventions; extending and sharing of expertise within the Region; strengthening of unions and communities; and redefining the role of industry toward development of safer products, with responsible marketing and reliable information.

  8. Atomic energy in Latin America

    International Nuclear Information System (INIS)

    Most countries in Latin America, including all those on the mainland, are Members of the Agency. Interest in the possibilities of nuclear energy has led to considerable activity, much of it in direct collaboration with the IAEA. Member States in the region are: Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Cuba, Dominican Republic, Ecuador, El Salvador, Guatemala, Haiti, Honduras, Jamaica, Mexico, Nicaragua, Panama, Paraguay, Peru, Uruguay, Venezuela. Of these, Argentina, Brazil, Colombia and Venezuela are operating, and Mexico and Uruguay are constructing, research reactors, while Chile and Peru are studying proposals. Argentina, Brazil, Mexico and Uruguay have all agreed to accept Agency safeguards for reactors. The possibility of future needs for nuclear power is under examination by several countries, in some cases being related to desalination of water. All atomic work in Latin America is devoted to peaceful uses, and note-worthy progress has been made with proposals for a treaty which would make the whole region a militarily de-nuclearized zone. It is proposed that when this comes into effect the Agency will be asked to apply the controls developed in its safeguards system, and to carry out the inspections necessary to establish that work in progress is solely for peaceful purposes

    2011-01-01

    Latin America is characterized by ethnic, geographical, cultural, and economic diversity; therefore, training in gastroenterology in the region must be considered in this context. The continent's medical education is characterized by a lack of standards and the volume of research continues to be relatively small. There is a multiplicity of events in general gastroenterology and in sub-disciplines, both at regional and local levels, which ensure that many colleagues have access to information. Medical education programs must be based on a clinical vision and be considered in close contact with the patients. The programs should be properly supervised, appropriately defined,and evaluated on a regular basis. The disparity between the patients' needs, the scarce resources available, and the pressures exerted by the health systems on doctors are frequent cited by those complaining of poor professionalism. Teaching development can play a critical role in ensuring the quality of teaching and learning in universities.Continuing professional development programs activities must be planned on the basis of the doctors' needs, with clearly defined objectives and using proper learning methodologies designed for adults. They must be evaluated and accredited by a competent body, so that they may become the basis of a professional regulatory system. The specialty has made progress in the last decades, offering doctors various possibilities for professional development. The world gastroenterology organization has contributed to the speciality through three distinctive, but closely inter-related, programs: Training Centers, Train-the-Trainers, and Global Guidelines, in which Latin America is deeply involved.

    Wind Power Activities by Country: Developers/Owners, Wind Plant Sizes, Wind Turbines Deployed, Commissioning Dates, Market Share, and Capacity Forecasts Latin American markets are a subject of intense interest from the global wind industry. Wind plant construction across Latin America is modest compared to the more established markets like the United States, Europe, and China, but it is an emerging market that is taking off at a rapid pace. The region has become the hottest alternative growth market for the wind energy industry at a time when growth rates in other markets are flat due to a variety of policy and macroeconomic challenges. Globalization is driving sustainable economic growth in most Latin American countries, resulting in greater energy demand. Wind is increasingly viewed as a valuable and essential answer to increasing electricity generation across most markets in Latin America. Strong wind resources, coupled with today's sophisticated wind turbines, are providing cost-effective generation that is competitive with fossil fuel generation. Most Latin American countries also rely heavily on hydroelectricity, which balances well with variable wind generation. Navigant Research forecasts that if most wind plants under construction with planned commissioning go online as scheduled, annual wind power installations in Latin America will grow from nearly 2.2 GW in 2013 to 4.3 GW by 2022. This Navigant Research report provides a comprehensive view of the wind energy market dynamics at play in Latin America. It offers a country-by-country analysis, outlining the key energy policies and development opportunities and barriers and identifying which companies own operational wind plants and which wind turbine vendors supplied those projects. Market forecasts for wind power installations, capacity, and market share in Latin America, segmented by country and company, extend through 2022. The report also offers an especially close analysis of Brazil and Mexico

    Kenneth N. Waltz's 1979 book, Theory of International Politics, is the most influential in the history of the discipline. It worked its effects to a large extent through raising the bar for what counted as theoretical work, in effect reshaping not only realism but rivals like liberalism and......-empiricism and anti-positivism of his position. Followers and critics alike have treated Waltzian neorealism as if it was at bottom a formal proposition about cause-effect relations. The extreme case of Waltz being so victorious in the discipline, and yet being consistently mis-interpreted on the question of...

  17. SOUTH AMERICA: INDUSTRIAL ROUNDWOOD SUPPLY POTENTIAL

    Directory of Open Access Journals (Sweden)

    Ronalds W. Gonzalez

    2008-02-01

    Full Text Available South America has substantial potential to expand its forest plantations and raw material supply. From 1997 to 2005, South America had a high annual growth rate in the production of industrial roundwood, with Brazil and Chile being the most important countries. In the same period, Asia had the only negative regional production growth rate in the world, and China became the largest round wood importer in the world. This paper summarizes the status of production, consumption, imports, and exports of industrial roundwood and forest products in South America. Produc-tion and exports from South America have continually increased at annual growth rates exceeding the forestry sector in general and the U.S. in particular. Based on timber growing investments to date, a strong timber production and forest products manufacturing sector has developed in the Southern Cone countries of Chile, Brazil, Argentina, and Uruguay, and is increasing in other countries in Latin America. There will be continued opportunities for forest plantations and new manufacturing facilities throughout South America, tempered somewhat by perceived country financial and political risks. These opportunities will allow South America to increase its share of world production and increase imports to North America and to Asia.

    This chapter argues that nominalization, as a subordination strategy, is significantly more pervasive in South America than would be predicted on the basis of global patterns. The patterns found within South America are most consistent with a scenario of several smaller spreads, possibly promoted by a few language families with major extensions (e.g. Quechuan, Tupian, Cariban).

  7. Biomass energy in Central America

    International Nuclear Information System (INIS)

    The objective of this paper is to introduce the concept of biomass to energy issues and opportunities in Central America. In this region, made up of seven countries (Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua and Panama), the biomass sector has the potential to play a crucial role in alleviating the environmental and development predicaments faced by all economies of the region. This paper assesses the available biomass resources at the regional and country levels and gives an overview of the current utilization of biomass fuels. It also describes the overall context in which the biomass-to-energy initiatives are immersed. At the regional level, biomass energy consumption accounts for more than 50% of total energy consumption. In regard to the utilization of biomass for energy purposes, it is clear that Central America faces a critical juncture at two levels, both mainly in rural areas: in the productive sector and at the household level. The absence of sustainable development policies and practices has jeopardized the availability of biomass fuels, particularly wood. Firewood is an important source of energy for rural industries such as coffee processing, which is one of the largest productive activities in the region. This paper comments on some of the most successful technological innovations already in place in the region, for instance, the rapid development of co-generation projects by the sugar cane industry, especially in El Salvador and Guatemala, the substitution of coffee husks for firewood in coffee processing plants in Costa Rica and El Salvador and the sustainable use of pine forests for co-generation in Honduras. Only one out of every two inhabitants in Central America now has access to electricity from the public grid. Biomass fuels, mainly firewood but also, to a lesser extent, other crop residues such as corn stalks, are the main source of energy for cooking and heating by most of the population. (It is foreseen that by the end

  8. Training centres in Latin America

    International Nuclear Information System (INIS)

    Early 1958 the Brazilian representative on the Board of Governors of the International Atomic Energy Agency - supported by the Governors from Argentina and Guatemala -proposed that a study should be made of the possibility of setting up one or more atomic energy training centres in Latin America. On the Board's recommendation, the Director General of the Agency appointed a fact-finding team to make anon-the-spot study. In drafting this report the team was invited to consider the following points: (a) The need for establishing one or more regional training centres; (b) Existing facilities that are being or could be used for training, together with technical data concerning them; (c) The general scientific technological and industrial conditions of the countries visited insofar as they have a bearing on their training needs and capabilities. The authors of the report conclude that 'a training centre in radio-botany should provide vitally needed knowledge and vitally needed specialists to all the agricultural installations in Latin America. A training centre like this might provide an excellent model upon which to base training centres in other areas'. The report recommends that: 1. The Agency should meet the requests of Latin American universities by, for example, supplying equipment and sending experts; 2. At least one specialized training centre should be established as soon as possible. Taking as an example the field of radio-botany, such a centre would provide trained specialists in radio-botany to agricultural institutions throughout Latin America and also provide basic research results vital to agriculture. The cost of new facilities might be of the order of $7 500 000, with an annual budget of approximately $650 000. Staff required: 40 scientists and 175 employees; 3. Whenever it appears feasible to gather necessary staff of high creative ability and established productivity and when funds can be made available for facilities, equipment and operating costs, at

  10. Developing nanotechnology in Latin America

    International Nuclear Information System (INIS)

    This article investigates the development of nanotechnology in Latin America with a particular focus on Argentina, Brazil, Chile, and Uruguay. Based on data for nanotechnology research publications and patents and suggesting a framework for analyzing the development of R and D networks, we identify three potential strategies of nanotechnology research collaboration. Then, we seek to identify the balance of emphasis upon each of the three strategies by mapping the current research profile of those four countries. In general, we find that they are implementing policies and programs to develop nanotechnologies but differ in their collaboration strategies, institutional involvement, and level of development. On the other hand, we find that they coincide in having a modest industry participation in research and a low level of commercialization of nanotechnologies.

    1988-01-01

    The widespread gravity coverage of North America provides a picture of the gross structural fabric of the continent via the trends of gravity anomalies. The structural picture so obtained reveals a mosaic of gravity trend domains, many of which correlate closely with structural provinces and orogenic terranes. The gravity trend map, interpreted in the light of plate-tectonic theory, thus provides a new perspective for examining the mode of assembly and growth of North America. Suture zones, palaeosubduction directions, and perhaps, contrasting tectonic histories may be identified using gravity patterns.

  13. Fermilab-Latin America collaboration

    International Nuclear Information System (INIS)

    Fermilab's program of collaboration with Latin America was initiated by then-Director Leon Lederman about 1980. His goal was to aid Latin American physics, and particularly its particle physics; this latter aim is in keeping with the Laboratory's particle physics mission. The reasons for collaboration between institutions in the US and Latin America are many, including geographic and cultural, together with the existence of many talented scientists and many centers of excellence in the region. There are also broader reasons; for example, it has been stated frequently that physics is the basis of much technology, and advanced technology is a necessity for a country's development. There is nothing unique about Fermilab's program; other US institutions can carry out similar activities, and some have carried out individual items in the past. On the Latin American side, such collaboration enables institutions there to carry out forefront physics research, and also to have the advantages of particle physics spin-offs, both in expertise in related technologies and in scientist training. In addition to particle physics, collaboration is possible in many other related areas. Although particle physics is frequently viewed as open-quotes big scienceclose quotes, all of the large research groups in the field are composed of many small university groups, each of which contributes to the experiment, the analysis and the physics. Fermilab is an international laboratory, open to all users; a research proposal is accepted on scientific merit and technical competence, not on the country of origin of the scientists making the proposal. Currently, of Fermilab's approximately 1400 users, about 30% are from non-US institutions. It should be noted here that Fermilab's funds, which come from the US government, are for particle physics only; however, there is some flexibility in interpretation of this

  14. Uncertainty assessments of climate change projections over South America

    Torres, Roger Rodrigues; Marengo, Jose Antonio

    2013-04-01

    This paper assesses the uncertainties involved in the projections of seasonal temperature and precipitation changes over South America in the twenty-first century. Climate simulations generated by 24 general circulation models are weighted according to the reliability ensemble averaging (REA) approach. The results show that the REA mean temperature change is slightly smaller over South America compared to the simple ensemble mean. Higher reliability in the temperature projections is found over the La Plata basin, and a larger uncertainty range is located in the Amazon. A temperature increase exceeding 2 °C is found to have a very likely (>90 %) probability of occurrence for the entire South American continent in all seasons, and a more likely than not (>50 %) probability of exceeding 4 °C by the end of this century is found over northwest South America, the Amazon Basin, and Northeast Brazil. For precipitation, the projected changes have the same magnitude as the uncertainty range and are comparable to natural variability.

    2011-10-01

    Comparative studies of the Raman and infrared spectra, the geometry, frequency and intensity of the vibrational bands of 5,7-dibromo-8-hydroxyquinoline (DBHQ) and 5,7-dichloro-8-hydroxyquinoline (DCHQ) were obtained by using Density Functional Theory calculations (DFT) with B3LYP functional and 6-311++G ** basis set. The effects of bromine and chlorine substituents on the vibrational frequencies of 8-hydroxyquinoline have been investigated. The assignments have been proposed with aid of the results of normal coordinate analysis. Coupling of vibrations have been determined by calculating potential energy distributions (PEDs). The molecular stability and bond strength was investigated by applying the Natural Bond Orbital analysis (NBO). The other molecular properties like Mulliken population analysis, thermodynamic functions and polarizabilities of the title compounds have been reported. The calculated HOMO and LUMO energies show that charge transfer occur in the molecules. Information about the size, shape, charge density distribution and site of chemical reactivity of the molecules has been obtained by mapping electron density isosurface with electrostatic potential (ESP).

  20. Supergravity theories

    International Nuclear Information System (INIS)

    Of all supergravity theories, the maximal, i.e., N = 8 in 4-dimension or N = 1 in 11-dimension, theory should perform the unification since it owns the highest degree of symmetry. As to the N = 1 in d = 11 theory, it has been investigated how to compactify to the d = 4 theories. From the phenomenological point of view, local SUSY GUTs, i.e., N = 1 SUSY GUTs with soft breaking terms, have been studied from various angles. The structures of extended supergravity theories are less understood than those of N = 1 supergravity theories, and matter couplings in N = 2 extended supergravity theories are under investigation. The harmonic superspace was recently proposed which may be useful to investigate the quantum effects of extended supersymmetry and supergravity theories. As to the so-called Kaluza-Klein supergravity, there is another possibility. (Mori, K.)

  9. Technical assistance in Latin America

    International Nuclear Information System (INIS)

    As in the other regions, nuclear technology development in Latin America reflects mainly the degree of technological development already existing in each country. It is quite significant that in nearly all countries in Latin America the medical profession has been the first to show interest in using nuclear techniques. As a result, a country such as Uruguay has become a source of recruitment for technical assistance experts in nuclear medicine to other developing countries, while at the same time it continues to receive assistance for new sophisticated techniques from the IAEA. Part of this assistance, in turn, comes from the neighbouring countries, Argentina and Brazil. For example, an expert from Uruguay is currently assigned under an Agency programme to Costa Rica, El Salvador and Guatemala, and experts from Argentina and Brazil have been sent to Uruguay. This is an example of 'horizontal' development, meaning mutual assistance between developing countries under programmes supported by the United Nations Agencies, which is now being emphasized by the United Nations Development Programme (UNDP). Still in the field of nuclear medicine, another significant model is provided by Bolivia. With assistance from the IAEA, and thanks to the availability of a good professional infrastructure in that country, a net of nuclear medicine services has been started, consisting of a well-developed nuclear medicine centre in La Paz and regional centres in Cochabamba, Sucre and Santa Cruz. Because of its great variations in altitude, Bolivia is in the position of being able to conduct research on the adaptation of man to diverse environmental conditions. The Agency has contributed, and continues to do so, to these programmes by sending experts, providing for training abroad of Bolivian doctors under its fellowship programmes, and providing basic equipment for all four centres. Independently of the cases described above, the IAEA has implemented or is implementing a considerable

  11. From upstream to downstream: Megatrends and latest developments in Latin America`s hydrocarbons sector

    Energy Technology Data Exchange (ETDEWEB)

    Wu, Kang; Pezeshki, S.; McMahon, J.

    1995-08-01

    In recent years, Latin America`s hydrocarbons sector has been characterized by reorganization, revitalization, regional cooperation, environmental awakening, and steady expansion. The pattern of these changes, which appear to be the megatrends of the region`s hydrocarbons sector development, will continue during the rest of the 1990s. To further study the current situation and future prospects of Latin America`s hydrocarbons sector, we critically summarize in this short article the key issues in the region`s oil and gas development. These megatrends in Latin America`s hydrocarbons sector development will impact not only the future energy demand and supply in the region, but also global oil flows in the North American market and across the Pacific Ocean. Each country is individually discussed; pipelines to be constructed are discussed also.

    Full Text Available The number of buffaloes in the American continent is growing at the explosive rate of 12.7 % a year, well above all other continents. Within this context the different situations of the southern part of South America are described, those countries that two hundred years ago were part of the River Plate Viceroyship and the Chile General Command, both of them part of the Spanish empire. The first steps of buffaloes in Paraguay, Bolivia and Uruguay. The expansion of buffaloes in Argentina and their recent start up in Chile. The production systems in the region are described, principally Argentina and Paraguay. The major changes and expansion of agriculture in Argentina are displacing cattle production from the North towards the Tropics, where buffalo has proven to be very superior in productivity compared to cattle production thanks to its very good adaptation to the local conditions. In Paraguay, a totally subtropical country, something very similar is happening. Paraguay has consolidated its sales of buffalo hides and beef. Argentina is well on its way to having a very efficient buffalo beef marketing competing with cattle of the highest quality. Buffalo milk production is still not mature in these countries, although there are several projects underway in Uruguay, Bolivia and Argentina.

    This final report summarizes the work conducted by the Building America Industrialized Housing Partnership (www.baihp.org) for the period 9/1/99-6/30/06. BAIHP is led by the Florida Solar Energy Center of the University of Central Florida and focuses on factory built housing. In partnership with over 50 factory and site builders, work was performed in two main areas--research and technical assistance. In the research area--through site visits in over 75 problem homes, we discovered the prime causes of moisture problems in some manufactured homes and our industry partners adopted our solutions to nearly eliminate this vexing problem. Through testing conducted in over two dozen housing factories of six factory builders we documented the value of leak free duct design and construction which was embraced by our industry partners and implemented in all the thousands of homes they built. Through laboratory test facilities and measurements in real homes we documented the merits of 'cool roof' technologies and developed an innovative night sky radiative cooling concept currently being tested. We patented an energy efficient condenser fan design, documented energy efficient home retrofit strategies after hurricane damage, developed improved specifications for federal procurement for future temporary housing, compared the Building America benchmark to HERS Index and IECC 2006, developed a toolkit for improving the accuracy and speed of benchmark calculations, monitored the field performance of over a dozen prototype homes and initiated research on the effectiveness of occupancy feedback in reducing household energy use. In the technical assistance area we provided systems engineering analysis, conducted training, testing and commissioning that have resulted in over 128,000 factory built and over 5,000 site built homes which are saving their owners over $17,000,000 annually in energy bills. These include homes built by Palm Harbor Homes, Fleetwood, Southern Energy

    Full Text Available In addition to increasing our knowledge and understanding of the naturalists who explored America at various times, particularly in the 18th and 19th centuries, we seek to discuss the personal, intimate, private, and sentimental nature of individuals who are usually described as well-bred, parsimonious, unfeeling, objective, rigorous, and methodical. For the same reason, perhaps, they are assumed to have stayed aloof from any form of sentimental or passionate relationships in the course of their excursions, despite the fact that the latter often lasted not for months but for years, and that in some instances were not conducted overland but involved prolonged voyages on the high seas.

    Además de avanzar en el conocimiento y comprensión de los naturalistas que exploraron América en algún momento, particularmente en los siglos XVIII y XIX, nos interesa relevar la dimensión personal, íntima, privada, sentimental, de sujetos que corrientemente son presentados como hombres comedidos, parcos, fríos, objetivos, rigurosos y metódicos y, tal vez por eso, se supone, ajenos a cualquier tipo de relación sentimental o pasional durante sus excursiones. Esto, a pesar de que muchas de ellas se prolongaron no ya por meses, sino que por años y que algunas de ellas no fueron itinerarios terrestres, sino que esencialmente marítimos, con largas temporadas en alta mar.

  6. Continuity and rupture: the fall of ‹‹Mel›› Zelaya in a comparative perspective

    Directory of Open Access Journals (Sweden)

    Mariana LLANOS

    2010-09-01

    Full Text Available This article analyses and compares the breakdown of the Honduran presidency of Manuel Zelaya with other presidential crises in Latin America during the Third Wave of democratization. Applying theory from analyses of presidential breakdowns, this work studies the procedures, causes and consequences of this presidential breakdown. The fall of Zelaya was caused by an escalating inter-institutional conflict, which was driven by the national, civilian elites. In a comparative perspective, the case is unique due to the military intervention, by invitation from the civil institutions, the lack of popular mobilisation before the crisis, and the international crisis and street conflicts after the presidential breakdown. The case of Honduras contributes to the theory of presidential breakdowns by raising attention to the role of the military and the state of the democratic regime within which the crisis occurs.

  12. Aquatic risk assessment of pesticides in Latin America.

    Carriquiriborde, Pedro; Mirabella, Paula; Waichman, Andrea; Solomon, Keith; Van den Brink, Paul J; Maund, Steve

    2014-10-01

    Latin America is anticipated to be a major growth market for agriculture and production is increasing with use of technologies such as pesticides. Reports of contamination of aquatic ecosystems by pesticides in Latin America have raised concerns about potential for adverse ecological effects. In the registration process of pesticides, all countries require significant data packages on aquatic toxicology and environmental fate. However, there are usually no specific requirements to conduct an aquatic risk assessment. To address this issue, the Society of Environmental Toxicology and Chemistry organized a workshop that brought together scientists from academia, government, and industry to review and elaborate on aquatic risk assessment frameworks that can be implemented into regulation of pesticides in Latin America. The workshop concluded that the international framework for risk assessments (protection goals, effects, and exposure assessments, risk characterization, and risk mitigation) is broadly applicable in Latin America but needs further refinement for the use in the region. Some of the challenges associated with these refinements are discussed in the article. It was recognized that there is potential for data sharing both within and outside of the region where conditions are similar. However, there is a need for research to compare local species and environmental conditions to those in other jurisdictions to be able to evaluate the applicability of data used in other countries. Development should also focus on human resources as there is a need to build local capacity and capability, and scientific collaboration and exchange between stakeholders in industry, government, and academia is also important. The meeting also emphasized that, although establishing a regionally relevant risk assessment framework is important, this also needs to be accompanied by enforcement of developed regulations and good management practices to help protect aquatic habitats

  13. A magmatic probe of dynamic topography beneath western North America

    Science.gov (United States)

    Klöcking, M.; White, N. J.; Maclennan, J.

    2014-12-01

    A region centered on the Yellowstone hotspot and encompassing the Colorado Plateau sits at an elevation 2 km higher than the cratonic North America. This difference broadly coincides with tomographically observed variations in lithospheric thickness: ~120 km beneath western North America, ~240 km beneath the craton. Thermochronology of the Grand Canyon area, sedimentary flux to the Gulf of Mexico, and river profile inversion all suggest that regional uplift occurred in at least two separate stages. High resolution seismic tomographic models, using USArray data, have identified a ring of low velocity material beneath the edges of the Colorado Plateau. Magmatism coincides with these low velocity zones and shows distinct phases: an overall increase in volume around 40 Ma and a change from lithospheric to asthenospheric signatures around 5 Ma. Volcanism is also observed to migrate north-east with time. Here, we attempt to integrate these different observations with lithospheric thickness. A dynamic topography model of progressive lithospheric erosion over a hot mantle plume might account for uplift as well as the temporal and spatial distribution of magmatism across western North America. Thinning of the lithosphere around the edges of the Colorado Plateau in combination with the hotter mantle potential temperature of a plume could create isostatic and dynamic uplift as well as allowing for melt production. To test this model, we have analysed around 100 samples from volcanic centers across western North America by ICP-MS for rare earth elements (REE). Most of the samples are younger than 5 Ma, and all of them have previously been analysed by XRF. Using trace element ratios such as La/Yb and Nb/Y we assess depth of melting and melt fraction, respectively. In addition, we use REE inversion modelling to estimate melt fractions as a function of depth and temperature of melting. The results are compared to existing constraints on lithospheric thickness and mantle potential

  14. Comparing 'Popular' and 'State' education in Latin Americaand Europe

    Directory of Open Access Journals (Sweden)

    2013-04-01

    Full Text Available In the 1970s, a radical adult education movement in Latin America, operating outside the state and engaging in what it called 'popular education', sparked world-wide interest in its educational theory and practice. More recently, with a change in state formations in Latin America, the movement has reconsidered its potential relationship with the state. Though Europe has its own history of popular education, some have argued that advanced economies and welfare states co-opted any strong independent educational movement: today popular education is more likely to take place 'within and against' the state, rather than outside it. Based on literature review, personal interviews and site visits, this article (a discusses what is understood by popular education (b outlines the development of popular education in Latin America, examining its relationship with different types of state (c considers differences between Latin America and Europe and what, if anything, popular educators in the two regions might learn from each other.

  16. Dual Double Field Theory

    CERN Document Server

    Bergshoeff, Eric A; Penas, Victor A; Riccioni, Fabio

    2016-01-01

    We present the dual formulation of double field theory at the linearized level. This is a classically equivalent theory describing the duals of the dilaton, the Kalb-Ramond field and the graviton in a T-duality or O(D,D) covariant way. In agreement with previous proposals, the resulting theory encodes fields in mixed Young-tableau representations, combining them into an antisymmetric 4-tensor under O(D,D). In contrast to previous proposals, the theory also requires an antisymmetric 2-tensor and a singlet, which are not all pure gauge. The need for these additional fields is analogous to a similar phenomenon for "exotic" dualizations, and we clarify this by comparing with the dualizations of the component fields. We close with some speculative remarks on the significance of these observations for the full non-linear theory yet to be constructed.

  17. An Expansion of Comparative Advantage Theory Based on "Sustainability" Factor%基于“可持续性”要素的比较优势理论拓展

    Institute of Scientific and Technical Information of China (English)

    杨青龙

    2012-01-01

    Comparative advantage is the difference of opportunity cost among different countries producing the same product. Traditional theories hold that the opportunity cost forming the comparative advantage is mainly production cost. "Sustainability" is a kind of inter-generational public goods, and the opportunity cost of sustainable attrition is inter-generational cost, i. e. the future potential net income abandoned when using some factors now. Therefore, sustainable diversity of different countries embodies discrepancy in inter-generational cost, and " sustainability" is a new factor shaping a country's comparative advantage. If China' s foreign trade excessively depends on comparative advantage of labor force and environment based on cheap labor force and loose environmental regulation policy, it is not sustainable in the long run. We can gradually achieve compatibility of the short-term rationality and the long-term one in the development of foreign trade through the internalization of inter-generational cost. Furthermore, China has to cope with the relationship between trade growth and the consumption of various scarce factors properly, balance the relationship between trade growth and sustainable development, and seek the equilibrium between the gross amount and structure of the present and future trade.%比较优势是不同国家生产同种产品的机会成本差异.传统理论认为,形成比较优势的机会成本主要为生产成本,而“可持续性”是一种代际公共品,耗费“可持续性”要素的机会成本是代际成本,即现在使用某(些)要素所放弃的未来使用之可能带来的纯收益.因此,不同国家的可持续性差异体现为代际成本差异,“可持续性”是塑造一国比较优势的新要素.着中国对外贸易过度依靠当代所具有的劳动力价格低廉和环境规制政策宽松所塑造的劳动力比较优势和环境比较优势,从长期看是不可持续的.通过代际成本内在化,可

    Dogma holds that the Caribbean Plate and its islands formed in the Pacific and comprise oceanic crust and intra- oceanic arc rocks. Middle America, between N and S America, manifests a regional, N35°E and N60°W tectonic fabric. The NE trend results from Triassic-Jurassic reactivation of Palaeozoic convergent structures as extensional faults during Pangean rifting and commencement of N America drift. The NW trend parallels major inter-continental faults and oceanic fractures along which extension and drift occurred. Triassic-Jurassic red beds accumulated in the NE trending, intra-continental rifts of N, S and Central America. Proximal extended continental margins subsided to accommodate thick Cretaceous carbonate sections (Florida - Bahamas, Campeche, Nicaragua Rise). Distal margins formed continental blocks flanked by seaward-dipping wedges. Seismic and drilling in basins along the eastern seaboard of N America (Baltimore Canyon to Blake Plateau) document Triassic-Jurassic red beds overlain by salt and carbonates. Hydrocarbons are present. In Middle America the Gulf of Mexico remained "intra-continental", surrounded by continental blocks (N America, Maya, Florida). The area further south experienced greater extension, manifest by diverging oceanic fracture patterns to the east and west. Seismic data over the Caribbean Plateau reveal deep architecture of NE trending highs flanked by dipping wedges of reflections, similar to eastern N America distal basins. DSDP drilling calibrated the overlying smooth seismic Horizon B" as recording Cenomanian basalts. Smoothness, great lateral extent and coeval exposed sections with palaeosols followed by shallow marine carbonates suggest they were sub-aerial. Adjacent, rough seismic Horizon B" probably records top of submarine, serpentinized mantle. Seismic over the plateau also reveals features identical to drilled Sigsbee salt diapirs of the Gulf of Mexico. The regional tectonic fabric demonstrates a shared geological history

    2016-01-01

    Full Text Available The political map of Latin America experienced some significant changes during the first decade of the 21st century. After a long period of political and social hegemony of right-wing coalitions, progressive parties assumed office in many countries. Their programs criticised the neoliberal model and underlined the role of the State in the development process. In that context, the 2008 world economic crisis strengthened the debate on the role of the State, particularly in what regards to its rapport with elites and foreign capital, as well as its capacity to lead a development strategy towards more prosperous and just societies. This article revisits two theoretical paradigms (the Neoliberal State and the Developmental State in the light of new approaches from different disciplinary grounds (Political Science, Economic History, Political Economy of Development. We argue the greatest challenge of a new theory and practice of the State in Latin America is to build broad developmental coalitions that are able to counter the centrifugal interests of local elites and transnational corporations.

  19. Undocumented Migration from Latin America in an Era of Rising U.S. Enforcement

    OpenAIRE

    Massey, Douglas S.; Riosmena, Fernando

    2010-01-01

    Available data have consistently pointed up the failure of U.S. policies to reduce undocumented migration from Latin America. To shed light on the reasons for this failure, we estimated a series of dynamic models of undocumented entry into and exit from the United States. Our estimates suggest that undocumented migration is grounded more in mechanisms posited by social capital theory and the new economics of labor migration rather than neoclassical economics. As a result, U.S. efforts to incr...

    In the context of gradual Cenozoic cooling, the timing of the onset of significant Northern Hemisphere glaciation 2.7 million years ago is consistent with Milankovitch’s orbital theory, which posited that ice sheets grow when polar summertime insolation and temperature are low. However, the role of moisture supply in the initiation of large Northern Hemisphere ice sheets has remained unclear. The subarctic Pacific Ocean represents a significant source of water vapour to boreal North America, ...

  1. At Last the Internationalization of Retail Banking? The Case of the Spanish Banks in Latin America

    OpenAIRE

    Mauro F. Guillén; Tschoegl, Adrian E.

    1999-01-01

    Since 1995 two Spanish banks -- Banco Santander Central Hispano and Banco Bilbao Vizcaya -- have become the largest foreign banks in retail banking in Latin America. This recent development merits careful analysis because foreign direct investment is rare in retail banking. We find that the Spanish banks are exhibiting asset-seeking, asset-exploiting, and oligopolistic behaviors, thus posing no serious challenge to established theories of foreign investment. We discuss the implications for re...

  2. Are civil wars to blame for crime in Central America?

    Directory of Open Access Journals (Sweden)

    Ana Sofia Cardenal Izquierdo

    2008-04-01

    Full Text Available The countries of Central America are high up on the list of nations with the highest crime rates in the world. According to the literature, the most common argument is that these high crimerates are a legacy of the armed conflicts of the 1980s. This article subjects this theory to an empirical examination. Even though the analysis is preliminary and limited, the results serve to question theexistence of such a link between war and crime. The data show that the areas most affected by war in El Salvador and Guatemala are not the ones that show the highest rates of crime. Furthermore, no direct relation exists between the presence of armed conflict and crime rates at a national level. The presence of armed conflict is neither a necessary factor nor a sufficient one for criminal violence. Onthe contrary, this work points to a close link between inequality and crime rates at a national level.

  3. A synthetic seismicity model for the Middle America Trench

    Science.gov (United States)

    Ward, Steven N.

    1991-01-01

    A novel iterative technique, based on the concept of fault segmentation and computed using 2D static dislocation theory, for building models of seismicity and fault interaction which are physically acceptable and geometrically and kinematically correct, is presented. The technique is applied in two steps to seismicity observed at the Middle America Trench. The first constructs generic models which randomly draw segment strengths and lengths from a 2D probability distribution. The second constructs predictive models in which segment lengths and strengths are adjusted to mimic the actual geography and timing of large historical earthquakes. Both types of models reproduce the statistics of seismicity over five units of magnitude and duplicate other aspects including foreshock and aftershock sequences, migration of foci, and the capacity to produce both characteristic and noncharacteristic earthquakes. Over a period of about 150 yr the complex interaction of fault segments and the nonlinear failure conditions conspire to transform an apparently deterministic model into a chaotic one.

  4. Cardiovascular Research Publications from Latin America between 1999 and 2008. A Bibliometric Study

    International Nuclear Information System (INIS)

    Cardiovascular research publications seem to be increasing in Latin America overall. To analyze trends in cardiovascular publications and their citations from countries in Latin America between 1999 and 2008, and to compare them with those from the rest of the countries. We retrieved references of cardiovascular publications between 1999 and 2008 and their five-year post-publication citations from the Web of Knowledge database. For countries in Latin America, we calculated the total number of publications and their citation indices (total citations divided by number of publications) by year. We analyzed trends on publications and citation indices over time using Poisson regression models. The analysis was repeated for Latin America as a region, and compared with that for the rest of the countries grouped according to economic development. Brazil (n = 6,132) had the highest number of publications in1999-2008, followed by Argentina (n = 1,686), Mexico (n = 1,368) and Chile (n = 874). Most countries showed an increase in publications over time, leaded by Guatemala (36.5% annually [95%CI: 16.7%-59.7%]), Colombia (22.1% [16.3%-28.2%]), Costa Rica (18.1% [8.1%-28.9%]) and Brazil (17.9% [16.9%-19.1%]). However, trends on citation indices varied widely (from -33.8% to 28.4%). From 1999 to 2008, cardiovascular publications of Latin America increased by 12.9% (12.1%-13.5%) annually. However, the citation indices of Latin America increased 1.5% (1.3%-1.7%) annually, a lower increase than those of all other country groups analyzed. Although the number of cardiovascular publications of Latin America increased from 1999 to 2008, trends on citation indices suggest they may have had a relatively low impact on the research field, stressing the importance of considering quality and dissemination on local research policies

  6. Anti-creationism in America

    Science.gov (United States)

    Park, Hee-Joo

    This thesis documents the development of organised anti-creationism in America. The revival of creationism culminated in the late 1970s with the success of creationists' national campaign for the introduction of legislation mandating "equal-time" for scientific creationism and evolution in the public schools. This prompted a proliferation of local protest groups which were eventually linked by the network called the Committees of Correspondence. This network became the political arm of the anti-creation movement at the grass-roots level. On the other hand, a small group of evolutionists responded to the creationist arguments by launching a journal, Creation/Evolution, which disseminated anti-creationism arguments. At the educational front, the National Association of Biology Teachers led the battle. These political, polemical and educational efforts were combined and evolved into the National Center for Science Education in 1986. With the NCSE, the evolution camp for the first time had its own full-time defenders to oppose large well-financed anti-evolution efforts. It appears, however, that the impact of organised anti-creationism was fairly limited. Evidence suggests that, despite anti-creationists' concerted efforts, the creationist movement in the nineties is as vigorous as ever and its influence on public beliefs about origins of the organic world remains strong. Gallup Polls have consistently shown that almost half of the adult population in the U.S. believes in the creation of humans about 10,000 years ago. Despite this dismal situation, major scientific bodies have failed to become directly engaged in the anti-creationism campaign due to their concern over public relation. Scientific organisations depend on public support for their research funds and therefore they generally do not want to offend the public by directly challenging its cherished beliefs such as creationism. Therefore, the ongoing battle has been largely left in the hands of individual

  10. The ribbon continent of northwestern South America

    Science.gov (United States)

    Altamira-Areyan, Armando

    The tectonic structure of the Plate Boundary Zone (PBZ) between the Caribbean Plate (CARIB) and the South American Plate (SOAM) is interpreted using models that require CARIB motion from the Pacific into the Atlantic. Those models can be subdivided into: (1) those in which the island arc rocks that are now in the CARIB-SOAM PBZ have collided with the northern South America margin, either obliquely or directly during the Cretaceous or during the Cenozoic, and (2) those in which the island arc rocks now in the CARIB-SOAM PBZ collided with the west coast of South America during the Cretaceous and were transferred to the northern margin by transform motion during the Cenozoic. Magnetic anomalies were first rotated in the Central and South Atlantic, holding Africa fixed to establish how much NOAM had converged on SOAM during the Cenozoic. WSW convergence was discovered to have been accommodated in the northern boundary of the CARIB. There is no evidence of convergence in the form of Cenozoic island arc igneous rocks on the north coast of South America. Those results are consistent only with models of Class (2) that call for transform movement of material that had collided with the west coast of South America along the CARIB-SOAM PBZ on the northern margin of South America. 40Ar/39Ar ages of island arc rocks from northern Venezuela were found to be older than ca 70 Ma, which is consistent with a requirement of models of Class (2) that those rocks are from an island arc which collided with the west coast of South America during Cretaceous times. Testing that conclusion using data from Ecuador, Colombia, Venezuela, the Netherlands Antilles, Trinidad and Tobago has led to the construction of a new ribbon continent model of the northwestern Cordillera of South America. Because the part of the ribbon continent on the north coast of South America has been experiencing substantial deformation in the Maracaibo block during the past 10 m.y., structures in that body have had to be

  11. Uncertainty theory

    Liu, Baoding

    2015-01-01

    When no samples are available to estimate a probability distribution, we have to invite some domain experts to evaluate the belief degree that each event will happen. Perhaps some people think that the belief degree should be modeled by subjective probability or fuzzy set theory. However, it is usually inappropriate because both of them may lead to counterintuitive results in this case. In order to rationally deal with belief degrees, uncertainty theory was founded in 2007 and subsequently studied by many researchers. Nowadays, uncertainty theory has become a branch of axiomatic mathematics for modeling belief degrees. This is an introductory textbook on uncertainty theory, uncertain programming, uncertain statistics, uncertain risk analysis, uncertain reliability analysis, uncertain set, uncertain logic, uncertain inference, uncertain process, uncertain calculus, and uncertain differential equation. This textbook also shows applications of uncertainty theory to scheduling, logistics, networks, data mining, c...

    CERN Document Server

    Kleiss, Ronald H P

    1999-01-01

    In these lectures I will build up the concept of field theory using the language of Feynman diagrams. As a starting point, field theory in zero spacetime dimensions is used as a vehicle to develop all the necessary techniques: path integral, Feynman diagrams, Schwinger-Dyson equations, asymptotic series, effective action, renormalization etc. The theory is then extended to more dimensions, with emphasis on the combinatorial aspects of the diagrams rather than their particular mathematical structure. The concept of unitarity is used to, finally, arrive at the various Feynman rules in an actual, four-dimensional theory. The concept of gauge-invariance is developed, and the structure of a non-abelian gauge theory is discussed, again on the level of Feynman diagrams and Feynman rules.

  14. Valence excitation energies of alkenes, carbonyl compounds, and azabenzenes by time-dependent density functional theory: Linear response of the ground state compared to collinear and noncollinear spin-flip TDDFT with the Tamm-Dancoff approximation

    Science.gov (United States)

    Isegawa, Miho; Truhlar, Donald G.

    2013-04-01

    Time-dependent density functional theory (TDDFT) holds great promise for studying photochemistry because of its affordable cost for large systems and for repeated calculations as required for direct dynamics. The chief obstacle is uncertain accuracy. There have been many validation studies, but there are also many formulations, and there have been few studies where several formulations were applied systematically to the same problems. Another issue, when TDDFT is applied with only a single exchange-correlation functional, is that errors in the functional may mask successes or failures of the formulation. Here, to try to sort out some of the issues, we apply eight formulations of adiabatic TDDFT to the first valence excitations of ten molecules with 18 density functionals of diverse types. The formulations examined are linear response from the ground state (LR-TDDFT), linear response from the ground state with the Tamm-Dancoff approximation (TDDFT-TDA), the original collinear spin-flip approximation with the Tamm-Dancoff (TD) approximation (SF1-TDDFT-TDA), the original noncollinear spin-flip approximation with the TDA approximation (SF1-NC-TDDFT-TDA), combined self-consistent-field (SCF) and collinear spin-flip calculations in the original spin-projected form (SF2-TDDFT-TDA) or non-spin-projected (NSF2-TDDFT-TDA), and combined SCF and noncollinear spin-flip calculations (SF2-NC-TDDFT-TDA and NSF2-NC-TDDFT-TDA). Comparing LR-TDDFT to TDDFT-TDA, we observed that the excitation energy is raised by the TDA; this brings the excitation energies underestimated by full linear response closer to experiment, but sometimes it makes the results worse. For ethylene and butadiene, the excitation energies are underestimated by LR-TDDFT, and the error becomes smaller making the TDA. Neither SF1-TDDFT-TDA nor SF2-TDDFT-TDA provides a lower mean unsigned error than LR-TDDFT or TDDFT-TDA. The comparison between collinear and noncollinear kernels shows that the noncollinear kernel

    Science.gov (United States)

    Tikly, Leon

    1999-11-01

    The article considers the relevance of recent developments in postcolonial theory for comparative education research. The article starts with an account of these developments. This account is then used as a basis for a critical discussion of previous theoretical frameworks that have been used by comparative researchers to explain the colonial legacy. The implications of adopting a postcolonial approach in comparative education are discussed in relation to issues of race, culture, language and the curriculum. The article concludes by arguing that a consideration of the postcolonial condition is necessary for developing a more holistic and less eurocentric understanding of the relationship between globalisation and education.

    1993-05-01

    This paper is an attempt to synthesize several models of health and levels of affluence in Latin America. An analysis is accomplished wherein various countries and regions of Latin America are classified for health purposes as either products of a poverty model or a wealth model. Variables utilized include: mortality rates in preschool children and infants; elderly mortality; life expectancy; and overall causes of death. All three of the general models can be found in different parts of Latin America. More developed countries and regions tend to approximate the wealth model where chronic and degenerative diseases dominate. Still, while life expectations are shorter in countries and regions with lower levels of development, some elderly are afflicted by chronic and degenerative diseases. PMID:8511622

    The freshwater and marine fish faunas of South America are the most diverse on Earth, with current species richness estimates standing above 9100 species. In addition, over the last decade at least 100 species were described every year. There are currently about 5160 freshwater fish species, and the estimate for the freshwater fish fauna alone points to a final diversity between 8000 and 9000 species. South America also has c. 4000 species of marine fishes. The mega-diverse fish faunas of South America evolved over a period of >100 million years, with most lineages tracing origins to Gondwana and the adjacent Tethys Sea. This high diversity was in part maintained by escaping the mass extinctions and biotic turnovers associated with Cenozoic climate cooling, the formation of boreal and temperate zones at high latitudes and aridification in many places at equatorial latitudes. The fresh waters of the continent are divided into 13 basin complexes, large basins consolidated as a single unit plus historically connected adjacent coastal drainages, and smaller coastal basins grouped together on the basis of biogeographic criteria. Species diversity, endemism, noteworthy groups and state of knowledge of each basin complex are described. Marine habitats around South America, both coastal and oceanic, are also described in terms of fish diversity, endemism and state of knowledge. Because of extensive land use changes, hydroelectric damming, water divergence for irrigation, urbanization, sedimentation and overfishing 4-10% of all fish species in South America face some degree of extinction risk, mainly due to habitat loss and degradation. These figures suggest that the conservation status of South American freshwater fish faunas is better than in most other regions of the world, but the marine fishes are as threatened as elsewhere. Conserving the remarkable aquatic habitats and fishes of South America is a growing challenge in face of the rapid anthropogenic changes of the 21

It treats several areas not commonly found between the covers of a single book: the physics of plasticity, constitutive theory, dynamic plasticity, large-deformation plasticity, and numerical methods, in addition to a representative survey of problems treated by classical methods, such as elastic-plastic problems, plane plastic flow, and limit analysis; the problem discussed come from areas of interest to mechanical, structural, and

  6. Ramsey theory

    OpenAIRE

    Hočevar, Mitja

    2015-01-01

    This BCs thesis deals with topics from graph theory. Ramsey theory in its most basic form deals with the problem of determining the minimal positive integer, such that for any edge-coloring of the complete graph of this size with a prescribed number of colors one can find a subgraph of predefined size all of whose edges are of the same colour. These minimal sizes are called Ramsey numbers. In this BCs thesis we present basic notions of graph theory needed to understand the basic theorem of...

    Andrews, George E

    1994-01-01

    Although mathematics majors are usually conversant with number theory by the time they have completed a course in abstract algebra, other undergraduates, especially those in education and the liberal arts, often need a more basic introduction to the topic.In this book the author solves the problem of maintaining the interest of students at both levels by offering a combinatorial approach to elementary number theory. In studying number theory from such a perspective, mathematics majors are spared repetition and provided with new insights, while other students benefit from the consequent simpl

    From ages to ages there had been expectation of individuals on a specific predictions and future occurrences. So also in a game, different participant that involves in those specified game have their various expectations of the results or the output of the game they are involved in. That is why we need a mathematical theory that helps in prediction of the future expectations in our day to day activities. Therefore the Martingale Theory is a very good theory that explains and dissects the expe...

  12. The Use of Government-Initiated Referendums in Latin America: Towards a Theory of Referendum Causes El uso de los referendos de iniciativa gubernamental en América Latina: Hacia una teoría sobre las causas del uso de votaciones populares iniciadas por el gobierno

    2009-01-01

    Full Text Available Over the past two decades there has been a considerable increase in the number of referendums worldwide. The existing literature on direct democracy has so far failed to explain this phenomenon by delivering a consistent theory on the causes of referendums. This explorative study aims at undertaking steps toward closing this gap by focusing on the specific type of facultative government-initiated referendums (FGIR and their use in presidential systems. Using QC A (a case-sensitive technique based on the formal logic of Boolean algebra, this study systematically compares the political opportunity structures of 49 presidential systems from 12 Latin American countries to detect the factors that spurred or obstructed the occurrence of FGIR. It concludes that FGIR are closely linked to high levels of party system fragmentation and divided government, i.e. two factors which have long been deemed problematic in the context of presidential systems, while their obstruction is mainly owed to the specific constitutional provisions regulating the referendum device.En las últimas dos décadas Ma existido alrededor del mundo un considerable aumento en el número de votaciones populares.

  15. Continuity theory

    CERN Document Server

    Nel, Louis

    2016-01-01

    This book presents a detailed, self-contained theory of continuous mappings. It is mainly addressed to students who have already studied these mappings in the setting of metric spaces, as well as multidimensional differential calculus. The needed background facts about sets, metric spaces and linear algebra are developed in detail, so as to provide a seamless transition between students' previous studies and new material. In view of its many novel features, this book will be of interest also to mature readers who have studied continuous mappings from the subject's classical texts and wish to become acquainted with a new approach. The theory of continuous mappings serves as infrastructure for more specialized mathematical theories like differential equations, integral equations, operator theory, dynamical systems, global analysis, topological groups, topological rings and many more. In light of the centrality of the topic, a book of this kind fits a variety of applications, especially those that contribute to ...

  19. Poverty and Corruption in Latin America, Callenges for a Sustainable Development Strategy

    Directory of Open Access Journals (Sweden)

    Ana Estefanía Carballo

    2010-11-01

    Full Text Available The effects of corruption on country-level economic performance are part of a dynamic debate in the social sciences, concerning the measure and monitoring of corruption. In Latin America, the coexistence of high poverty levels with high economic growth rates continues to be a puzzling situation that may be partly explained by corruption and institutional quality indicators. This study discusses the links between poverty and corruption, by constructing an econometric model that compares corruption measurements with poverty and development indicators for Latin America, for the 1998-2008 decade.
