  1. Rethinking political correctness.

    Legal and cultural changes over the past 40 years ushered unprecedented numbers of women and people of color into companies' professional ranks. Laws now protect these traditionally underrepresented groups from blatant forms of discrimination in hiring and promotion. Meanwhile, political correctness has reset the standards for civility and respect in people's day-to-day interactions. Despite this obvious progress, the authors' research has shown that political correctness is a double-edged sword. While it has helped many employees feel unlimited by their race, gender, or religion,the PC rule book can hinder people's ability to develop effective relationships across race, gender, and religious lines. Companies need to equip workers with skills--not rules--for building these relationships. The authors offer the following five principles for healthy resolution of the tensions that commonly arise over difference: Pause to short-circuit the emotion and reflect; connect with others, affirming the importance of relationships; question yourself to identify blind spots and discover what makes you defensive; get genuine support that helps you gain a broader perspective; and shift your mind-set from one that says, "You need to change," to one that asks, "What can I change?" When people treat their cultural differences--and related conflicts and tensions--as opportunities to gain a more accurate view of themselves, one another, and the situation, trust builds and relationships become stronger. Leaders should put aside the PC rule book and instead model and encourage risk taking in the service of building the organization's relational capacity. The benefits will reverberate through every dimension of the company's work.

    Two experiments explored the ramifications of endorsing color blindness as a strategy for appearing unprejudiced. In Study 1, Whites proved adept at categorizing faces on the basis of race, but understated their ability to do so. In Study 2, Whites playing the Political Correctness Game--a matching task that requires describing other individuals--were less likely to use race as a descriptor when paired with a Black partner than when paired with a White partner, a strategy that impaired communication and performance. In addition, avoidance of race was associated with Whites making less eye contact with and appearing less friendly toward Black partners.

  5. The Unreasonable Destructiveness of Political Correctness in Philosophy

    2017-08-01

    Full Text Available I submit that epistemic progress in key areas of contemporary academic philosophy has been compromised by politically correct (“PC” ideology. First, guided by an evolutionary account of ideology, results from social and cognitive psychology and formal philosophical methods, I expose evidence for political bias in contemporary Western academia and sketch a formalization for the contents of beliefs from the PC worldview taken to be of core importance, the theory of social oppression and the thesis of anthropological mental egalitarianism. Then, aided by discussions from contemporary epistemology on epistemic values, I model the problem of epistemic appraisal using the frameworks of multi-objective optimization theory and multi-criteria decision analysis and apply it to politically correct philosophy. I conclude that philosophy guided by politically correct values is bound to produce constructs that are less truth-conducive and that spurious values which are ideologically motivated should be abandoned. Objections to my framework stemming from contextual empiricism, the feminine voice in ethics and political philosophy are considered. I conclude by prescribing the epistemic value of epistemic adequacy, the contextual value of political diversity and the moral virtue of moral courage to reverse unwarranted trends in academic philosophy due to PC ideology.

The difference in this direction from the classical international specialization is that it is at the intersection of several disciplines: military science, military-technical and military-industrial as well as International Relations. A specialist in military and political issues should not only be an expert in the field of international relations and diplomacy, but also have a deep knowledge of military-technical issues to understand the basic trends in the development of scientific and technological progress and its impact on the balance of forces in the world. Global changes in the balance of power and the nature of the conflict, the emergence of new types of weapons are changing the basic methods and approaches to the art of war, which requires a science-based perspective on problem solving and multi-disciplinary approach in achieving the goals. Military and political studies allow us to understand how the development of military technology and military organization of the state affected by the political situation in the world, the national security of the country and its place in the system of international relations. Military-political research has been developing at MGIMO for a few decades. It laid down the basis for a scientific school of political-military studies. Its founding fathers were such prominent scholars of international affairs, as I.G. Usachyov, A.D. Nikonov, A.G. Arbatov, V.G. Baranovsky, V.M. Kulagin, A.N. Nikitin and other well-known experts. Their work covers a wide range of military and political issues, including the topics of arms control and disarmament, international, and especially European security, military policy, NATO, the Western military-political doctrines and their practical application. Now the lead in the development of this research at MGIMO has taken Center for Military-Political Studies, which became a concentration of relevant

  7. Political Correctness and the System of Education: Selected Examples and Consequences

    Full Text Available This paper aims at analysing political correctness in the context of education. Political correctness has already been widely studied and commented on; however, the phenomenon has received surprisingly little attention in relation to schooling and, particularly, teachers. In the Polish system of education, political correctness is manifest first of all in the overt policy applied by people in charge of education, who refrain from using terminology of e.g. “free market,” “commercial value,” “product,” “competition,” or “profit,” which could be unfavourably received or assessed by teachers. It turns out that political correctness, though founded upon proper assumptions and ideally contributing to common good, can be incorrectly understood or used for political purposes, and thus lose its initial sense, thwart communication between politicians and teachers and hinder their mutual understanding or even render it impossible. This paper attempts to reveal yet another set of conditions, this time the language-related ones, in which contemporary teachers work.

    Reports an error in "Is Political Behavior a Viable Coping Strategy to Perceived Organizational Politics? Unveiling the Underlying Resource Dynamics" by Shuhua Sun and Huaizhong Chen ( Journal of Applied Psychology , Advanced Online Publication, May 22, 2017, np). In the article, Table 1 contained a formatting error. Correlation coefficient values in the last four cells of column 6 were misplaced with correlation coefficient values in the last four cells of column 7. All versions of this article have been corrected. (The following abstract of the original article appeared in record 2017-22542-001.) We conduct a theory-driven empirical investigation on whether political behavior, as a coping strategy to perceived organizational politics, creates resource trade-offs in moderating the relationship between perceived organizational politics and task performance. Drawing on conservation of resources theory, we hypothesize that political behavior mitigates the adverse effect of perceived organizational politics on task performance via psychological empowerment, yet exacerbates its adverse effect on task performance via emotional exhaustion. Three-wave multisource data from a sample of 222 employees and their 75 supervisors were collected for hypothesis testing. Findings supported our hypotheses. Our study enhances understandings of the complex resource dynamics of using political behavior to cope with perceived organizational politics and highlights the need to move stress-coping research from a focus on the stress-buffering effect of coping on outcomes to a focus on the underlying competing resource dynamics.

    2014-11-01

    Full Text Available We live in times that are particularly sensitive to issues such as freedom and are differentiated by strong aspirations for personal and societal freedom. One speaks of political-societal freedom, freedom of religion, artistic freedom and freedom to choose one’s own lifestyle. It would be possible to make a long list of the various kinds or manifestations of freedom, which modern individuals indentify in their lives. My essay considers the ways the law functions in regards to religious freedom in the context of the currently prevailing and implemented political visions in United Europe. Strictly speaking, this paper concerns the definition of place, which was assigned for religious convictions of citizens of the European Union and their role in shaping their personal and societal lives.

  12. Is the political animal politically ignorant? Applying evolutionary psychology to the study of political attitudes.

    Science.gov (United States)

    Petersen, Michael Bang; Aarøe, Lene

    2012-12-20

    As evidenced by research in evolutionary psychology, humans have evolved sophisticated psychological mechanisms tailored to solve enduring adaptive problems of social life. Many of these social problems are political in nature and relate to the distribution of costs and benefits within and between groups. In that sense, evolutionary psychology suggests that humans are, by nature, political animals. By implication, a straightforward application of evolutionary psychology to the study of public opinion seems to entail that modern individuals find politics intrinsically interesting. Yet, as documented by more than fifty years of research in political science, people lack knowledge of basic features of the political process and the ability to form consistent political attitudes. By reviewing and integrating research in evolutionary psychology and public opinion, we describe (1) why modern mass politics often fail to activate evolved mechanisms and (2) the conditions in which these mechanisms are in fact triggered.

  18. Cynical References to Political Correctness in Hungarian Media in the 2000s

    Directory of Open Access Journals (Sweden)

    Erzsébet Barát

    2011-01-01

    Full Text Available In this paper I analyze the strategy in Hungarian public discourse for discrediting feminism in the media in the early 2000s. The strategy consists in the systematic conflation of feminism with the demand for “politically correct” language. My analysis will show that the motivation for the conflation occurs, on the one hand, in the name of tolerance or, on the other, to the determent of feminism. These apparently very different discourses, however, overlap and are effects of the same strategy of discreditation. They both rest on the assumption that feminism is an exclusionary ideology hence it is to be tolerated at best, or to be fought mercilessly. Despite the apparent opposition between the two approaches, their goals are the same. The reduction of feminism to political correctness and its representation as the manifestation of some general practice of ‘language cleansing’ “benignly” masks the real object of feminist language criticism, namely, sexist and homophobic exclusionary language use and their symbolic and material consequences. These are found everywhere in contemporary Hungary. I shall argue that the alarming similarity of the two perspectives is a recent phenomenon in Hungarian public discourse that emerged in the first decade of the millennium. It replaces the strategy of the 1990s that represented feminism as a matter of some individual and isolated efforts and as such eventually harmless on a social scale. The turn of the first decade re-imagines feminism as a social practice that is argued to be an intolerant or aggressive attempt at purging language use. This change in the meaning of the concept is caused in part, I shall argue, by the stereotypical conceptualization of language use itself. The concept is stereotypical in that it draws on (value judgments expected to be understood as self-evident hence able to preempt any need for reflexivity on the part of the reader.

  20. 'It's got so politically correct now': parents' talk about empowering individuals with learning disabilities.

    Science.gov (United States)

    Jingree, Treena; Finlay, W M L

    2012-03-01

    Over the last decade the UK Government has made proposals to empower individuals with learning disabilities. Strategies have been implemented to reduce institutionalisation and social segregation. Consequently, some learning disability services are being phased out and the focus of care has moved away from institutions and into the community and family domain. Focusing on discourse as a site for social action and identity construction, we used critical discursive psychology to examine focus group discussions between family carers about facilitating the independence of adult family members with learning disabilities. Unlike official UK Government and learning disability services' constructions of empowerment policy, we found that parents invoked empowerment talk: (1) as a resource to construct the facilitation of independence as an abstract, irresponsible, politically correct professional trend; (2) dilemmatically with meritocratic or practical arguments to undermine notions of facilitating choices; and (3) as a resource to construct new service developments as contrary to the preferences of people with learning disabilities. Parents also described individuals with learning disabilities as unable to cope, and drew stark contrasts between their practice and those of service-professionals when expressing concerns about empowerment. We discuss possible implications of such discourses and contrasts on opportunities for empowering individuals with learning disabilities. © 2011 The Authors.

  1. Politicizing science: conceptions of politics in science and technology studies.

    Science.gov (United States)

    Brown, Mark B

    2015-02-01

    This essay examines five ideal-typical conceptions of politics in science and technology studies. Rather than evaluating these conceptions with reference to a single standard, the essay shows how different conceptions of politics serve distinct purposes: normative critique, two approaches to empirical description, and two views of democracy. I discuss each conception of politics with respect to how well it fulfills its apparent primary purpose, as well as its implications for the purpose of studying a key issue in contemporary democratic societies: the politicization of science. In this respect, the essay goes beyond classifying different conceptions of politics and also recommends the fifth conception as especially conducive to understanding and shaping the processes whereby science becomes a site or object of political activity. The essay also employs several analytical distinctions to help clarify the differences among conceptions of politics: between science as 'political' (adjective) and science as a site of 'politics' (noun), between spatial-conceptions and activity-conceptions of politics, between latent conflicts and actual conflicts, and between politics and power. The essay also makes the methodological argument that the politics of science and technology is best studied with concepts and methods that facilitate dialogue between actors and analysts. The main goal, however, is not to defend a particular view of politics, but to promote conversation on the conceptions of politics that animate research in social studies of science and technology.

  6. Donald Trump as a Cultural Revolt Against Perceived Communication Restriction: Priming Political Correctness Norms Causes More Trump Support

    Directory of Open Access Journals (Sweden)

    Lucian Gideon Conway

    2017-05-01

    Full Text Available Donald Trump has consistently performed better politically than his negative polling indicators suggested he would. Although there is a tendency to think of Trump support as reflecting ideological conservatism, we argue that part of his support during the election came from a non-ideological source: The preponderant salience of norms restricting communication (Political Correctness – or PC – norms. This perspective suggests that these norms, while successfully reducing the amount of negative communication in the short term, may produce more support for negative communication in the long term. In this framework, support for Donald Trump was in part the result of over-exposure to PC norms. Consistent with this, on a sample of largely politically moderate Americans taken during the General Election in the Fall of 2016, we show that temporarily priming PC norms significantly increased support for Donald Trump (but not Hillary Clinton. We further show that chronic emotional reactance towards restrictive communication norms positively predicted support for Trump (but not Clinton, and that this effect remains significant even when controlling for political ideology. In total, this work provides evidence that norms that are designed to increase the overall amount of positive communication can actually backfire by increasing support for a politician who uses extremely negative language that explicitly violates the norm.

    Chen, K.; Reiman, E.; Lawson, M.

    1995-01-01

    In order to reconstruct positron emission tomography (PET) images in quantitative dynamic studies, the data must be corrected for radioactive decay. One of the two commonly used methods ignores physiological processes including blood flow that occur at the same time as radioactive decay; the other makes incorrect use of time-accumulated PET counts. In simulated dynamic PET studies using 11 C-acetate and 18 F-fluorodeoxyglucose (FDG), these methods are shown to result in biased estimates of the time-activity curve (TAC) and model parameters. New methods described in this article provide significantly improved parameter estimates in dynamic PET studies

    The Fukushima Nuclear Reactor disaster of 2011 is still a continuing disaster three years later, although some experts have proclaimed the 4 reactors being already under control. It is surely an incredibly difficult task to properly terminate nuclear accidents. However, I should point out that the process of termination plan has been marred by too much of politics and business messing up a scientific approach to do it in a rational way. This blame must to go to both pro-nuclear and anti-nuclear power people. It makes me feel sad to see people not respecting science in executing such a difficult task. I shall list up where things went wrong with the hope that this kind of action, as I do here, would trigger people to get back to science to straighten out the execution process. I will show a few examples of published papers presenting the opinion that it is inappropriate what the Japanese government considers to be safe.

  17. Social positions and political recruitment: a study of Brazilian senators

    Directory of Open Access Journals (Sweden)

    Adriano Codato

    Full Text Available Abstract This article discusses the methodology for the definition, classification, and measurement of social positions of the parliamentary political elite. We present some theoretical and methodological strategies for classifying the variable “occupation held prior to political career”, and suggest the use of more than one indicator for this measurement. We argue that a typology of both social and political characteristics of parliament members is the best way to grasp the transformations on the patterns of political recruitment throughout the 20th century. The first model we tested classified Brazilian senators elected between 1918 and 2010 among occupations conventionally used in studies on political elites. The second applied model seeks to change the coding of occupations so as to grasp this group’s sociopolitical transformations over time. We conclude with a new classification suggestion, which results from a typology sensitive to the varying values ascribed to professional occupations throughout history.

These approaches being correct, nevertheless, dealing that is participating in some manner in the broad field of economic management had, on occasion, a social dimension that transcended by far the possible economic profit any businessman could naturally aspire to, even casting a shadow over the economic profit, reducing that aspect of his activity to the persecution of a purely social and ideological benefit. This profit did not derive straight from the specific economic activity but from the perception by the community of the reasons underlying the agent’s «extra-economic behaviour». This perception and the evaluation of these conducts, and the actors’ persecution of a behavioural model that positively fixed into that perception frame, explain a whole set of economical attitudes linked to the referential frameworks «service» and «common good». These attitudes were pursued by these individuals, were promoted by urban governments, and were positively perceived by the entire community.

    Towards the end of 2016, a milestone report from the International Energy Agency (IEA) set out what were described as the ''frontlines for additional emissions reductions'' in the global power sector in the years ahead. The tools for continuing efforts to rein in emissions and combat climate change include, according to the IEA's World Energy Outlook 2016, the ''accelerated deployment'' of renewables, carbon capture and storage, a ''strong push'' for greater electrification and efficiency across all end-uses and ''a robust and concerted'' clean energy research and development effort by governments and companies. Nuclear power was also included in the publication as one of the ways that countries could reduce emissions harmful to our planet.. although the IEA's report said nuclear's role would depend on it being ''politically acceptable''.

    Full Text Available The ideological dimension in textbooks is evidenced at different levels and through different discursive mechanisms. Following this, the objective of this paper is to demonstrate that certain social representations and politically correct attitudes (Courtine, 2006 are evidenced on the discursive materiality of textbooks. In this sense, we propose that politically correct gestures are not only configured through themes and words, present or silenced ones, but also through polyphonic and argumentative strategies. Among them, we focus on the forms identified as “autominic modalization” (Authier-Revuz, 1995 and we characterize them as modes of ideological positioning, in general, and as traces of a politically correct poses, in particular. Having a group of French authors as the theoretical framework for this study (Pêcheux, 1975, 1982, 1983; Courtine, 1982, 2006; Authier-Revuz, 1984, 1995; Amossy, 1999, we analyze a corpus of social science textbooks for secondary education, edited in Argentina between 1983 and 2005. On one hand, we show that one of the functions related to the “autonimic modalization” is based on having the locutor-author exhibiting disagreement when using a given disciplinary terminology. On the other hand, we corroborate that such ideological disagreement often evidences a politically correct attitude that is not necessarily accompanied with a transformation of the representations. In this way, stereotypes and social imagings are maintained through time and discourse, something that the “autonimic modalization” tried to avoid.

  2. Situating Poligen Studies: Between Moral Enquiry and Political Theory

    2017-12-01

    Full Text Available In this article, I argue that we can best appreciate those works that appeal to the notion of “political genealogy” as distinct forms of study by situating them between moral enquiry and political theory. They draw from moral enquiry the concern with how we ought to live but are not themselves prescriptive. They address the political constitution of our social lives but not as a theoretical object. Reversing the relation between enquiry and truth, political genealogies are historiographical studies motivated by forms of resistance that expose the will to truth of the present ordering of discourses, thereby releasing the hold such orderings have on what we think, say, and do to their on-going agonistic relations.

    The purpose of this paper is to examine key challenges associated with conducting politically sensitive research within a workplace setting, and to highlight strategic partnerships that can be developed to address these challenges. The author's research on employee mental health issues within a large healthcare facility serves as the foundation for identification and description of "political minefields" that investigators may encounter when conducting organizational case study research. Key methodological principles from the literature on qualitative case study research will frame discussion of how to understand and address political sensitivities in the research process. The benefits of conducting organizational case study research will be outlined, followed by discussion of methodological challenges that can emerge in negotiating entry, collecting data (gatekeepers, researcher reflexivity, participant authenticity and non-maleficence), and communicating research findings. Courage, collaboration and clear communication with stakeholders at all levels of the organization are critical to the success of workplace based case study research.

    The Canadian Light Source (CLS) Quantum Materials Spectroscopy Center (QMSC) beamline will employ a novel double period (55 mm, 180 mm) elliptically polarizing undulator (EPU) to produce photons of arbitrary polarization in the soft X-ray regime. The long period and high field of the 180 mm period EPU will have a strong dynamic focusing effect on the storage ring electron beam. We have considered two partial correction schemes, a 4 m long planar array of BESSY-II style current strips, and soft iron L-shims. In this paper we briefly consider the implementation of these correction schemes.

Minneapolis: University of Minnesota Press, 2009. xxvii + 242 pp. (Paper US$ 22.50 [First paragraph] Over the last ten years the field of Caribbean Studies has seen a precipitous expansion of work on sexualities, as recent review essays by Jenny Sharpe and Samantha Pinto (2006 and Kamala Kempadoo (2009 have observed. The three books under review here, all based on dissertation research and all published in 2009, make important contributions to this growing literature. While each one approaches sexual politics from a distinctive disciplinary, geographic, and theoretical vantage point, all three ask readers to take seriously the central place that sexual desires and practices occupy in the lives of Caribbean people, both at home and in the diaspora. Caribbean sexuality studies are still sometimes thought of as belonging to a domain outside of, or auxiliary to “real” politics, but these studies demonstrate without hesitation how sexuality functions as an important prism through which we might understand broader debates about ethics, politics, and economics in the region. Building from the insights of feminist theorists who connect the “private” realm to community, national, and global geopolitics, they show that sex is intimately connected to certain freedoms – be they market, corporeal, or political – as well as to their consequences. Taken together, they consider sexual subjectivity, political economy, and cultural production in unexpected ways and point to exciting new directions for the

    Using data from 28 countries in four continents, the present research addresses the question of how basic values may account for political activism. Study 1 (N = 35,116) analyses data from representative samples in 20 countries that responded to the 21-item version of the Portrait Values Questionnaire (PVQ-21) in the European Social Survey. Study 2 (N = 7,773) analyses data from adult samples in six of the same countries (Finland, Germany, Greece, Israel, Poland, and United Kingdom) and eight other countries (Australia, Brazil, Chile, Italy, Slovakia, Turkey, Ukraine, and United States) that completed the full 40-item PVQ. Across both studies, political activism relates positively to self-transcendence and openness to change values, especially to universalism and autonomy of thought, a subtype of self-direction. Political activism relates negatively to conservation values, especially to conformity and personal security. National differences in the strength of the associations between individual values and political activism are linked to level of democratization. © 2014 The British Psychological Society.

  16. Is evolutionary biology becoming too politically correct? A reflection on the scala naturae, phylogenetically basal clades, anatomically plesiomorphic taxa, and 'lower' animals.

    Science.gov (United States)

    Diogo, Rui; Ziermann, Janine M; Linde-Medina, Marta

    2015-05-01

    The notion of scala naturae dates back to thinkers such as Aristotle, who placed plants below animals and ranked the latter along a graded scale of complexity from 'lower' to 'higher' animals, such as humans. In the last decades, evolutionary biologists have tended to move from one extreme (i.e. the idea of scala naturae or the existence of a general evolutionary trend in complexity from 'lower' to "higher" taxa, with Homo sapiens as the end stage) to the other, opposite, extreme (i.e. to avoid using terms such as 'phylogenetically basal' and 'anatomically plesiomorphic' taxa, which are seen as the undesired vestige of old teleological theories). The latter view tries to avoid any possible connotations with the original anthropocentric idea of a scala naturae crowned by man and, in that sense, it can be regarded as a more politically correct view. In the past years and months there has been renewed interest in these topics, which have been discussed in various papers and monographs that tend to subscribe, in general, to the points defended in the more politically correct view. Importantly, most evolutionary and phylogenetic studies of tetrapods and other vertebrates, and therefore most discussions on the scala naturae and related issues have been based on hard tissue and, more recently, on molecular data. Here we provide the first discussion of these topics based on a comparative myological study of all the major vertebrate clades and of myological cladistic and Bayesian phylogenetic analyses of bony fish and tetrapods, including Primates. We specifically (i) contradict the notions of a scala naturae or evolutionary progressive trends leading to more complexity in 'higher' animals and culminating in Homo sapiens, and (ii) stress that the refutation of these old notions does not necessarily mean that one should not keep using the terms 'phylogenetically basal' and particularly 'anatomically plesiomorphic' to refer to groups such as the urodeles within the Tetrapoda

  18. Study of the orbital correction method

    International Nuclear Information System (INIS)

    Meserve, R.A.

    1976-01-01

    Two approximations of interest in atomic, molecular, and solid state physics are explored. First, a procedure for calculating an approximate Green's function for use in perturbation theory is derived. In lowest order it is shown to be equivalent to treating the contribution of the bound states of the unperturbed Hamiltonian exactly and representing the continuum contribution by plane waves orthogonalized to the bound states (OPW's). If the OPW approximation were inadequate, the procedure allows for systematic improvement of the approximation. For comparison purposes an exact but more limited procedure for performing second-order perturbation theory, one that involves solving an inhomogeneous differential equation, is also derived. Second, the Kohn-Sham many-electron formalism is discussed and formulae are derived and discussed for implementing perturbation theory within the formalism so as to find corrections to the total energy of a system through second order in the perturbation. Both approximations were used in the calculation of the polarizability of helium, neon, and argon. The calculation included direct and exchange effects by the Kohn-Sham method and full self-consistency was demanded. The results using the differential equation method yielded excellent agreement with the coupled Hartree-Fock results of others and with experiment. Moreover, the OPW approximation yielded satisfactory comparison with the results of calculation by the exact differential equation method. Finally, both approximations were used in the calculation of properties of hydrogen fluoride and methane. The appendix formulates a procedure using group theory and the internal coordinates of a molecular system to simplify the calculation of vibrational frequencies

    Full Text Available The aim of this paper is to present some results of a comparative study between the politeness strategies that two Spanish and two Brazilian professors would use, both in Portuguese and Spanish, in twelve hypothetical situations presented on a social behavior questionnaire. This work is based on a previous study published by Piatti (2003 in Argentina, where the author observed some pragmatic differences between a group of students of Spanish as a foreign language and a group of native speakers of the language. With her hypotheses as a starting point, the scope was moved to a small group of people with high communicative competence in both languages, in order to give a different insight on of the pragmatic differences that exist between Brazilians and the Spanish. Based on the findings, we have tried to establish some intercultural differences among the politeness strategies used in Brazil and in Spain.

    2011-04-01

    Full Text Available In today’s increasingly globalised yet disconnected world, especially in the contemporary context of a turbulent political landscape, there has been an increasing effort made by socio-political leaders at solidifying alliances and drawing support from different corners of the world in order to neutralize policies. Drawing on a multidimensional framework, in particular, critical discourse analysis and membership categorization analysis, this paper explores the various strategies employed by political leaders, attempting to reconcile disparate perspectives in the face of increasing socio-economic inter-connection and political dependence. More often than not, it was discovered, political leaders drew upon the somewhat “illusory” notion of “international community”, turning it into a tool of persuasion and membership category. In doing so, this paper aims to illustrate how the creation of illusive categories and perceptions are intended as a means of drawing support from diverse political leaders and projecting a united front before scrutinizing press and public.

    Tip loss correction is known to play an important role for engineering prediction of wind turbine performance. There are two different types of tip loss corrections: tip corrections on momentum theory and tip corrections on airfoil data. In this paper, we study the latter using detailed CFD...... computations for wind turbines with sharp tip. Using the technique of determination of angle of attack and the CFD results for a NordTank 500 kW rotor, airfoil data are extracted and a new tip loss function on airfoil data is derived. To validate, BEM computations with the new tip loss function are carried out...... and compared with CFD results for the NordTank 500 kW turbine and the NREL 5 MW turbine. Comparisons show that BEM with the new tip loss function can predict correctly the loading near the blade tip....

  4. The Europeanization of Politics: Building a Terminology for European Studies

    Directory of Open Access Journals (Sweden)

    Damir Grubiša

    2005-01-01

    Full Text Available The article discusses the problem of Europeanisation, one of the key concepts developed within the European Studies in the last ten years or so, since the adoption and entry into force of the Maastricht Treaty. The fi rst part of the article deals with various models of Europeanisation in a context extending beyond the conceptual framework of the European Union, within which the phenomenon of Europeanisation arises. Therefore, the author attempts to develop a typology of broader approaches to the identifi cation of the phenomenon and process of Europeanisation, which includes six conceptions thereof: the fi rst approach is a geographical-political one, where Europeanisation is seen as a change in outer borders of Europe, from the reduction of Europe to the countries of Western Europe and Central Europe, to the extension of the concept of Europe to marginal countries; the second approach links the concept of Europeanisation with the development of political institutions on the European level. The third defi nition identifi es Europeanisation as an export of various forms of political organisation, a process which proceeds from the experience of European colonisation to the diff usion of European values as a role model for other continents; the fourth model of Europeanisation is the identifi cation with the project of European unifi cation, i. e. the process of integration which ends up in a federal, unifi ed Europe; the fi fth subtype is the penetration of national systems of governance by the European model of multilevel governance, which becomes manifest in the adaptation, convergence and harmonisation of the political and legal systems of member nations. The author elaborates on this classic typology by adding the sixth approach, which he calls “retrospective Europeanisation”. It involves Europeanisation as identifi cation with traditional European values that existed before EC and EU, primarily with the preintegration traditional

    2015-10-01

    Full Text Available To gain and retain political power, politicians use the media to persuade the masses to vote and support them, especially during elections. Barisan Nasional (BN has successfully used the media to maintain its power for the past 57 years, making it the longest-serving elected government in the world still currently in office. However, the emergence of the Internet has challenged the status quo. The purpose of the research was to investigate how new media has influenced the political process and communication strategies in Malaysia and its impact on the political landscape. The researcher interviewed 19 respondents: politicians, bloggers and media consultants from both sides of the political divide. The findings showed that new media, especially Web 2.0, has expanded the public sphere and enabled more Malaysians to participate in the democratic process, through information dissemination, mobilisation or crowd-sourcing. However, the cyber-war between BN and the opposition Pakatan Rakyat (PR has caused confusion and disinformation, affecting the quality of democratic decision-making. Nevertheless, new media has enabled more voices to emerge and challenge the political hegemony.

    Taking a qualitative approach, this study sought to describe consumer attitudes toward political participation and the association between political engagement and social recovery. This study used data from seven focus groups of self-identified consumers of mental health services in the New York City area (N=52). Attitudes and behaviors related to voting and other forms of political engagement were identified and classified according to grounded theory, with a focus on the relationship between political engagement and broader social functioning, participation, and recovery. Participants described the symbolic meaning of voting and political participation in terms of connection to social inclusion versus exclusion. Participants described political participation as a component of empowerment for minority groups in general, including persons who use mental health services and those from racial-ethnic minority groups. Qualitative studies of the symbolic meanings of political participation are an important component of understanding the broad yet interconnected dimensions of social recovery.

On the other hand, research in international and comparative education demonstrates how conflicts and power asymmetries continue to characterize…

  14. Use of the discourse analysis method to study current political practice (by the example of representation of the political leader image

    2016-01-01

    Full Text Available The potentialities in the application of the discourse analysis method to study a political discourse as a current political practice are shown. The authors, using the Foucault methodology, offer a sociological definition for the political discourse. It is the authors’ opinion that the approach mentioned allows investigating a political discourse as a practice for the formation of a certain reality, specific agents, institutions and organizations. A political discourse is a simulative dynamic model of political area where various subdiscourses interact, thus creating their own ideas of policy, symbols and images. Subdiscourses of political leaders become dominating. Inasmuch as a political discourse in a current political system is carried out with the aid of mass media, it could be considered as a media discourse of policy. The authors consider the representation as a basic mechanism for the formation of a political discourse, by the example of the representation of the image of V.V. Putin, the President of the Russian Federation. The representation of a political leader image in a political discourse has a number of peculiarities. It is carried out on the basis of certain principles with the aid of the system of political codes. Empiric investigations allowed making a conclusion that the main symbolic image for the Russian President is an image of a super-hero. It is the authors’ opinion, the image of V.V. Putin as a leader super-hero is determined by the specificity of the Russian political culture within the limits of which a leader is a center of power establishing an authoritarian style of ruling. The authors show the process of the political legitimacy displacement from the institutional level to the personal one by means of mass media. A political leader gains a status of a subject establishing moral, social and value reference points for the whole of the society.

    Full Text Available We analyze the properties of various methods for bias-correcting parameter estimates in both stationary and non-stationary vector autoregressive models. First, we show that two analytical bias formulas from the existing literature are in fact identical. Next, based on a detailed simulation study, we show that when the model is stationary this simple bias formula compares very favorably to bootstrap bias-correction, both in terms of bias and mean squared error. In non-stationary models, the analytical bias formula performs noticeably worse than bootstrapping. Both methods yield a notable improvement over ordinary least squares. We pay special attention to the risk of pushing an otherwise stationary model into the non-stationary region of the parameter space when correcting for bias. Finally, we consider a recently proposed reduced-bias weighted least squares estimator, and we find that it compares very favorably in non-stationary models.

  18. Performing Femininity in Japanese Politics: Chikage Ogi Case Study

    Directory of Open Access Journals (Sweden)

    2016-07-01

    Full Text Available Women’s access to the political sphere in Japan has been limited by structural constraints which perpetuate their roles primarily as housewives and mothers. Some women who seek to become professional politicians use these images of traditional femininity as a deliberate tactic in political campaigns to provide a culturally acceptable way for them to express their political views. This paper analyses the life of Chikage Ōgi, a Japanese politician who was once a Takarazuka actress, in order to develop a deeper understanding of the ways in which gender-role expectations restrict women’s access to opportunities throughout their life course and the pragmatic ways that women strive to achieve their goals despite this. Ōgi used the performance skills she developed during her time as an actress to enhance her political image and fulfil her political ambitions. This paper highlights Ōgi’s creativity in enacting agency in Japan’s male-dominated political sphere and demonstrates the complex ways she both upheld and subverted gender norms in order to achieve political longevity.

    2012-07-01

    Full Text Available The objective of the research is to explore learner attitudes to correction of mistakes or feedback as a language learning tool in oral, electronically- and paper-written work as well as peer correction of mistakes.Feedback is a method used in the teaching of languages to improve performance by sharing observations, concerns and suggestions with regard to written work or oral presentation. It includes not only correcting learners, but also assessing them. Both correction and assessment depend on mistakes being made, reasons for mistakes, and class activities. Recently the value of feedback in language studies has been a matter of debate among language teaching practitioners. The research into the effects of feedback is far from conclusive. Teachers’ and students’ expectations toward feedback are found to be opposing, and the most frequent reason given is its negative impact on students’ confidence and motivation. However, at the university level the issue of feedback has been examined in passing and there is insufficient research into learner attitudes to feedback in English for Specific Purposes.The hypothesis for the present study is to find out whether criticism has a negative impact on student confidence and whether perceptions of feedback depend on professional specialization.The research methods. A survey of students’ perceptions of teachers’ feedback in various class activities was administered to various groups of undergraduate students of psychology and penitentiary law.

  5. West German nuclear politics: a study of international cooperative behavior

    Driscoll, R.F.

    1983-01-01

    This dissertation is an investigation of the motivations behind West German policies and behavior in the area of nuclear politics. It examines and attempts to explain this behavior using a taxonomy built around the factors of vulnerability, power, domestic support, and autonomy. These are called international cooperative behavior factors. Chapters I and II develop the taxonomy and define the factors in terms of the Federal Republic. Chapter III covers the period up through the functioning of the Nuclear Planning Group, while Chapter IV analyzes NATO's December 1979 modernization decision. The presentation is less chronological and more selective: it focuses on the four international cooperative behavior factors as explanatory concepts. Chapter V examines the utility of the taxonomy. It concludes that the factors of autonomy, domestic support and vulnerability appear to be key in understanding and predicting West German nuclear behavior. The chapter then studies the potential applicability of the taxonomy to other nations or issues. It concludes that the factors are very nation-specific, but they do in fact provide a useful classification and explanatory scheme

  7. How Internal Political Efficacy Translates Political Knowledge Into Political Participation

    Science.gov (United States)

    Reichert, Frank

    2016-01-01

    This study presents evidence for the mediation effect of political knowledge through political self-efficacy (i.e. internal political efficacy) in the prediction of political participation. It employs an action theoretic approach—by and large grounded on the Theory of Planned Behaviour—and uses data from the German Longitudinal Election Study to examine whether political knowledge has distinct direct effects on voting, conventional, and/or unconventional political participation. It argues that political knowledge raises internal political efficacy and thereby indirectly increases the chance that a citizen will participate in politics. The results of mediated multiple regression analyses yield evidence that political knowledge indeed translates into internal political efficacy, thus it affects political participation of various kinds indirectly. However, internal political efficacy and intentions to participate politically yield simultaneous direct effects only on conventional political participation. Sequentially mediated effects appear for voting and conventional political participation, with political knowledge being mediated by internal political efficacy and subsequently also by behavioural intentions. The mediation patterns for unconventional political participation are less clear though. The discussion accounts for restrictions of this study and points to questions for answer by future research.

    Full Text Available Political cartoons are anything but innocent caricatures. They have been described as “a confrontational art form” (Oliphant 25, as “purposefully designed to elicit strong emotions and reactions from readers” (Long, Bunch, and Lloyd 651, and as “among the more extreme forms of expression” (Long, Bunch, and Lloyd 651. Stories abound with the harsh punishments endured by political cartoonists under oppressive regimes. One might even say that what allows liberal and conservative American cartoonists to feel any sense of solidarity with one another is their bond through the First Amendment and their belief in the democratic enterprise that is criticizing government.

    2012-05-01

    Full Text Available The byzantine society, de jure and de facto heir of the Greco-Roman world, has it’s own philosophy, it’s own structure model and policy thinking. Without doubt, for the New Rome this model is that sprang from the Christian teachings, and as a philosophy it harmoniously blends the legacy of the Roman world with Blessed Augustine’s thinking about man and city which itself is a symbiosis between the acquired pagan knowledge and Christian experience of the latter. The Byzantine fortress (The Empire-n.n. will use religion as the main instrument for political and social consolidation. Religion (Christianity – n.n. is, for the Byzantine monarchy , the path to divinity, immortality... The Byzantine Christianity is not just a "phrase invented by them" as in the words of Eminescu, but a complex mechanism which represents the totality of good concepts about the world and about life of the constantinopolitan city.In preparing this study we started from the model offered by St. Augustine, "De Civitate Dei", a model which compares the two types of cities - people's city, with all its flaws, and the City of God, personified by the Church to which the Christian Roman Empire provides the Regnum. Our study tries to reflect how the model of the two cities becomes a political ideology of the Byzantine Empire and, arch over time, how it is manifested in the public and political mind of the Romanian society. This research tries to increase the understanding of the mental archetypes amongst those who are active participants in public life in Romania. However, we want our message to be disseminated in a wider public and to provide the possibility of assimilation, as much as it can, of the participatory political culture. Thus, the study becomes an attempt of reporting the Byzantine society, respectively the current Romanian society, to the model of the three types of political culture offered by Almond and Verba - participatory, parochial and dependent.

  16. First a hero of science and now a martyr to science: the James Watson Affair - political correctness crushes free scientific communication.

    Science.gov (United States)

    Charlton, Bruce G

    2008-01-01

    In 2007 James D. Watson, perhaps the most famous living scientist, was forced to retire from his position and retreat from public life in the face of international mass media condemnation following remarks concerning genetically-caused racial differences in intelligence. Watson was punished for stating forthright views on topics that elite opinion has determined should be discussed only with elaborate caution, frequent disclaimers, and solemn deference to the currently-prevailing pieties. James Watson has always struck many people as brash; however this blunt, truth-telling quality was intrinsic to his role in one of the greatest scientific discoveries. Much more importantly than 'good manners', Watson has consistently exemplified the cardinal scientific virtue: he speaks what he understands to be the truth without regard for the opinion of others. The most chilling aspect of the Watson Affair was the way in which so many influential members of the scientific research community joined the media condemnation directed against Watson. Perhaps the most egregious betrayal of science was an article by editorialists of the premier UK scientific journal Nature. Instead of defending the freedom of discourse in pursuit of scientific truth, Nature instead blamed Watson for being 'crass' and lacking 'sensitivity' in discussing human genetic differences. But if asked to choose between the 'sensitive' editors of Nature or the 'crass' genius of James D. Watson, all serious scientists must take the side of Watson. Because when a premier researcher such as Watson is hounded from office by a vicious, arbitrary and untruthful mob; all lesser scientists are made vulnerable to analogous treatment at the whim of the media. A zealous and coercive brand of 'political correctness' is now making the biological truth of human genetic differences intolerably difficult to discover and discuss in US and UK. This needs to change. My hope is that truth will prevail over political correctness and

    This paper describes a possible skew quadrupole correction system for linear coupling effects for the RHIC92 lattice. A simulation study has been done for this correction system. Results are given for the performance of the correction system and the required strength of the skew quadrupole corrections. The location of the correctors is discussed. For RHIC92, it appears possible to use the same 2 family correction system for all the likely choices of β*. The simulation study gives results for the residual tune splitting that remains after correction with a 2 family correction system. It also gives results for the beta functions before and after correction

  19. Expectation Violation in Political Decision Making: A Psychological Case Study

    Directory of Open Access Journals (Sweden)

    Michael Öllinger

    2017-10-01

    Full Text Available Since the early Gestaltists there has been a strong interest in the question of how problem solvers get stuck in a mental impasse. A key idea is that the repeated activation of a successful strategy from the past results in a mental set (‘Einstellung’ which determines and constrains the option space to solve a problem. We propose that this phenomenon, which mostly was tested by fairly restricted experiments in the lab, could also be applied to more complex problem constellations and naturalistic decision making. We aim at scrutinizing and reconstructing how a mental set determines the misinterpretation of facts in the field of political decision making and leads in consequence to wrong expectations and an ill-defined problem representation. We will exemplify this psychological mechanism considering a historical example, namely the unexpected stabilization of the Franco regime at the end of World War II and its survival thereafter. A specific focus will be drawn to the significant observation that erroneous expectations were taken as the basis for decisions. This is congruent with the notion that in case of discrepancy between preconceived notions and new information, the former prevails over the new findings. Based on these findings, we suggest a theoretical model for expectation violation in political decision making and develop novel approaches for cognitive empirical research on the mechanisms of expectation violation and its maintenance in political decision making processes.

  20. Good governance and political culture: A case study of Bangladesh

    2016-12-01

    Full Text Available In a democratic system it is essential to have a competitive, and a tolerant party system, but Bangladesh has experienced an intolerant and a confrontational party system that has created a deadlock and brought uncertainty to the whole country. Since 1990, except 2014, Bangladesh has witnessed four systematic peaceful free elections, one each--in 1991, 1996, 2001, and 2008. On January 5, 2014, however, a controversial election took place in which major opposition political parties did not participate except the ruling alliance parties. The two dominant parties—the Bangladesh Nationalist Party (BNP and the Awami League (AL—each won two previous free and fair elections, with the BNP winning in1991, and a BNP-led 4-party coalition in 2001, and the AL in 1996, and an AL-led 14 party alliance in 2008. However, from 2014 Bangladesh is heading towards an authoritarian system. All these are happening due to the lack of good governance. This article intends to emphasize that the political culture emanating from the party politics is retarding good governance in Bangladesh. This article argues that the cultural traits developed in the last four decades in various dimensions,, particularly in more recent years, have worked as an “earth-worm” in the fabrics of democracy in Bangladesh preventing ‘good governance’.

  1. POLITICAL MONETARY CYCLES IN COALITION AND SINGLE PARTY GOVERNMENT PERIODS: A CASE STUDY ON TURKEY

    Full Text Available According to the theory of political monetary cycles, the government manipulates monetary policy during election periods in order to be re-elected. According to the said theory, expansionary monetary policies are implemented before the elections with opportunistic objective, while the contractionary monetary policies are implemented to stabilize the economy immediately after the elections. The use of monetary policy instruments for political purposes depends on the presence of a non-autonomous central bank, flexible exchange rate regime in the country, and the coordination between fiscal and monetary policies. Thus, the changes in the monetary policy indicators in election periods during coalition and single party governments in Turkey between 1990 and 2016 were examined in the present study. The money in circulation (M0, M1 money supply, domestic loans and inflation series were analyzed with the seasonal Box-Jenkins method for the above mentioned periods. Based on the findings of the study, political monetary cycles were not observed during the 1990-2000 coalition governments. It was determined that there were political monetary cycles during the single party government period between 2000 and 2016.Furthermore, although it could be expected that the political monetary cycles would be removed with the liberalization of the Turkish central bank on 25 April 2001, the existence of political monetary cycles during the period of 2000-2016 indicates that central bank independence was not fully achieved in Turkey. Based on another finding of the present study, the lack of political monetary cycles during the coalition government periods could lead to the failure in financing the budget deficit that increase due to political reasons with monetary policies. However, due to the existence of political monetary cycles during the single party government period, it could be argued that politically induced budget deficits changed in consistence with the

  2. Organizational Life and Political Incorporation of Two Asian Immigrant Groups: A Case Study.

    2009-10-14

    Civil society is the foundation of a healthy democracy but its immigrant element has received little attention. This paper is a case study of immigrant organizations of highly-skilled Asian Indians and Chinese immigrants in a suburban town of Edison, New Jersey. I find that civic participation of Asian Indian immigrants spills over into political incorporation while Chinese immigrant organizations remain marginalized. I argue the local processes of racialization are central in explaining differences in political incorporation of immigrants. In the local context, the Chinese are seen as successful but conformist model minorities and Asian Indians as invaders and troublemakers. The racialization of Asian Indians has resulted in more political activity and higher levels of political visibility of their organizations. The results highlight shortcomings of current assimilation theories, which give little space to civic and political incorporation and view human capital in an unqualifiedly positive light.

    The low-frequency characteristics of polycrystalline taurine were studied experimentally by terahertz (THz) absorption spectroscopy and theoretically by ab initio density-functional simulations. Full optimizations with semi-empirical dispersion correction were performed in spectral computations and vibrational mode assignments. For comparison, partial optimizations with pure density functional theory were conducted in parallel. Results indicate that adding long-range dispersion correction to the standard DFT better reproduces the measured THz spectra than the popular partial optimizations. The main origins of the observed absorption features were also identified. Moreover, a coupled-oscillators model was proposed to explain the experimental observation of the unusual spectral blue-shift with the increase of temperature. Such coupled-oscillators model not only provides insights into the temperature dynamics of non-bonded interactions but also offers an opportunity to better understand the physical mechanisms behind the unusual THz spectral behaviors in taurine. Particularly, the simulation approach and novel coupled-oscillators model presented in this work are applicable to analyze the THz spectra of other molecular systems.

  6. The justification of studies in genetic epidemiology - political scaling in China Medical City.

    2018-04-01

    Genetic epidemiology examines the role of genetic factors in determining health and disease in families and in populations to help addressing health problems in a responsible manner. This paper uses a case study of genetic epidemiology in Taizhou, China, to explore ways in which anthropology can contribute to the validation of studies in genetic epidemiology. It does so, first, by identifying potential overgeneralizations of data, often due to mismatching scale and, second, by examining it's embedding in political, historical and local contexts. The example of the longitudinal cohort study in Taizhou illustrates dimensions of such 'political scaling'. Political scaling is a notion used here to refer to the effects of scaling biases in relation to the justification of research in terms of relevance, reach and research ethics. The justification of a project on genetic epidemiology involves presenting a maximum of benefits and a minimum of burden for the population. To facilitate the delineation of political scaling, an analytical distinction between donating and benefiting communities was made using the notions of 'scaling of relevance', 'scaling of reach' and 'scaling of ethics'. Political scaling results at least partly from factors external to research. By situating political scaling in the context of historical, political and local discourses, anthropologists can play a complementary role in genetic epidemiology.

  8. Public political thought: bridging the sociological-philosophical divide in the study of legitimacy.

    The study of political legitimacy is divided between prescriptive and descriptive approaches. Political philosophy regards legitimacy as principled justification, sociology regards legitimacy as public support. However, all people can, and occasionally do engage in morally reasoning their political life. This paper thus submits that in studying socio-political legitimation - the legitimacy-making process - the philosophical ought and the sociological is can be bridged. I call this construct 'public political thought' (PPT), signifying the public's principled moral reasoning of politics, which need not be democratic or liberal. The paper lays PPT's foundations and identifies its 'builders' and 'building blocks'. I propose that the edifice of PPT is built by moral agents constructing and construing socio-moral order (nomization). PPT's building blocks are justificatory common beliefs (doxa) and the deliberative language of legitimation. I illustrate the merits of this groundwork through two empirical puzzles: the end of apartheid and the emergence of Québécois identity. © London School of Economics and Political Science 2016.

    Full Text Available The article analyzes the works of Soviet historians, who first turned to the study of the post-revolutionary political situation in Baku in the 1920s. Among them are S.E Sef, S.S. Shaumyan, G. Stein, etc. It is concluded that the aim of this authors was justification of Bolsheviks’ coming to power while neglecting the role of other political forces. This historiographical situation makes it necessary to identify different interpretations of the events related to the political situation in Baku in 1917−1918 in order to restore the objective picture of the past history of Azerbaijan.

    Full Text Available BackgroundThe effect of yoga in the reduction of depressive symptoms, anxiety, stress, anger as well as in the increased ability of behavioral control has been shown. These effects of yoga are highly relevant for prison inmates who often have poor mental health and low impulse control. While it has been shown that yoga and meditation can be effective in improving subjective well-being, mental health, and executive functioning within prison populations, only a limited number of studies have proved this, using randomized controlled settings.MethodsA total of 152 participants from nine Swedish correctional facilities were randomly assigned to a 10-week yoga group (one class a week; N = 77 or a control group (N = 75. Before and after the intervention period, participants answered questionnaires measuring stress, aggression, affective states, sleep quality, and psychological well-being and completed a computerized test measuring attention and impulsivity.ResultsAfter the intervention period, significant improvements were found on 13 of the 16 variables within the yoga group (e.g., less perceived stress, better sleep quality, an increased psychological and emotional well-being, less aggressive, and antisocial behavior and on two within the control group. Compared to the control group, yoga class participants reported significantly improved emotional well-being and less antisocial behavior after 10 weeks of yoga. They also showed improved performance on the computerized test that measures attention and impulse control.ConclusionIt can be concluded that the yoga practiced in Swedish correctional facilities has positive effects on inmates’ well-being and on considerable risk factors associated with recidivism, such as impulsivity and antisocial behavior. Accordingly, the results show that yoga practice can play an important part in the rehabilitation of prison inmates.

    Full Text Available The primary motivation for this research, in which a qualitative method was employed, was to examine political apathy amongst students at Nelson Mandela Metropolitan University. The secondary motivation was to question whether youth political apathy threatens the consolidation of democracy. The researchers arranged four focus groups at Nelson Mandela Metropolitan University. A purposive sampling technique was utilised. All 50 participants in the study were Nelson Mandela Metropolitan University undergraduate and postgraduate black students, with ages ranging from 21 to 35 years. The researchers encouraged participants to have maximum participation in the focus group deliberations. The researchers also made use of elite interviews in the study. The findings of this study suggest that political apathy does exist amongst students at Nelson Mandela Metropolitan University. Most of the participants in the focus groups indicated that young people in post-apartheid South Africa have no interest in politics.

    To investigate the association between political trust in the Riksdag and lack of belief in the possibility to influence one's own health (external locus of control), taking horizontal trust into account. The 2008 public health survey in Skåne is a cross-sectional postal questionnaire study with a 55% participation rate. A random sample of 28,198 persons aged 18-80 years participated. Logistic regression models were used to investigate the associations between political trust in the Riksdag (an aspect of vertical trust) and lack of belief in the possibility to influence one's own health (external locus of control). The multiple regression analyses included age, country of birth, education, and horizontal trust in other people. A 33.7% of all men and 31.8% of all women lack internal locus of control. Low (external) health locus of control is more common in higher age groups, among people born outside Sweden, with lower education, low horizontal trust, low political trust, and no opinion concerning political trust. Respondents with not particularly strong political trust, no political trust at all and no opinion have significantly higher odds ratios of external locus of control throughout the multiple regression analyses. Low political trust in the Riksdag seems to be independently associated with external health locus of control.

    Politics is a manifestation of the uniquely human ability to debate, decide, and reach consensus on decisions affecting large groups over long durations of time. Recent neuroimaging studies on politics have focused on the association between brain regions and specific political behaviors by adopting party or ideological affiliation as a criterion to classify either experimental stimuli or subjects. However, it is unlikely that complex political beliefs (i.e., "the government should protect freedom of speech") are evaluated only on a liberal-to-conservative criterion. Here we used multidimensional scaling and parametric functional magnetic resonance imaging to identify which criteria/dimensions people use to structure complex political beliefs and which brain regions are concurrently activated. We found that three independent dimensions explained the variability of a set of statements expressing political beliefs and that each dimension was reflected in a distinctive pattern of neural activation: individualism (medial prefrontal cortex and temporoparietal junction), conservatism (dorsolateral prefrontal cortex), and radicalism (ventral striatum and posterior cingulate). The structures we identified are also known to be important in self-other processing, social decision-making in ambivalent situations, and reward prediction. Our results extend current knowledge on the neural correlates of the structure of political beliefs, a fundamental aspect of the human ability to coalesce into social entities.

    Workplace victimization is considered a major social stressor with significant implications for the wellbeing of employees and organizations. The aim of this study was to examine the influences of employees' personality traits and organizational politics on workplace victimization among Ghanaian employees. Using a cross-sectional design, data were collected from 631 employees selected from diverse occupations through convenience sampling. Data collection tools were standardized questionnaires that measured experiences of negative acts at work (victimization), the Big Five personality traits, and organizational politics. The results from hierarchical multiple regression analysis showed that among the personality traits neuroticism and conscientiousness had significant, albeit weak relationships with victimization. Organizational politics had a significant positive relationship with workplace victimization beyond employees' personality. The study demonstrates that compared with personal characteristics such as personality traits, work environment factors such as organizational politics have a stronger influence on the occurrence of workplace victimization.

    Full Text Available During the reformation era much political coercion took place in Buleleng Regency, Bali.Such political coercion occured repeatedly in the general election referred to as Pemiluconducted in 1999 and 2004, and in the election conducted to directly vote for district headsreferred to as Pilkada in 2007. It is interesting to investigate this phenomenon. The problems inthis study are formulated as follows: (1 what factors causing political coercion to take place inthe general election and in the election conducted to directly vote for district heads; (2 how ittook place; and 3 what ideology leading to it and what implications it had on the socio-cultureof the people living in Buleleng Regency?The practical theory, the theory of coercion and the theory of ideology were eclecticallyadopted to establish and analyze concepts. Qualitative method is employed and the data neededwere collected by observation, in-depth interview, and documentation study.The results of the study show: first, the factors causing political coercion to take placevaried; second, six cases of political coercion in Buleleng Regency did not take place suddenly,but through processes and were related to the cultural coercion inherent within local individualsand groups; third, they took place through semiologic deconstruction related to themeaningfulness provided by the common people and political elites to the ‘pemilu and pilkada’.Thus, the ideologies responsible for political coercion were paternalism, binary opposition ,pragmatism and ‘premanisme’ (the broker of coercion ; fourth, the implications the cases ofpolitical coercion had on the people in Buleleng Regency were: the pattern of kinship becamebroken, the culture of physical coercion shifted to the culture of symbolic and economiccoercion; a new consensus was established.The conclusions withdrawn in this study show that the characteristics of the politicalcoercion taking place in Buleleng Regency during the reformation

    Full Text Available Objective: to study whether posthypoxic brain dysfunctions may be corrected by low-intensity laser irradiation an hour after hypovolemic hypotension at late postresuscitation stages (following 30 days. Material and methods. Experiments were carried out on high-anxious male albino rats weighing 280—300 g. The study model was one-hour hypovolemic hypotension (blood pressure 40 mm Hg, followed by blood reinfusion. The integrative brain function was evaluated from the indices of the rat orientative-trying behavior in the elevated cross labyrinth test. The depressive component of the rats’ behavior was examined in the forced swimming test. Plasma norepinephrine levels were measured. Laser irradiation was performed 30 days after blood reinfusion. Results. Laser irradiation used at late postresuscitation stages leads to the normalization of plasma norepinephrine levels, the reduction of anxiety in the rats, and their improved orientative-trying behavior. Conclusion. The positive impact of laser irradiation on the rat orientative-trying behavior is associated with its anxiolytic effect, in which the recovery of autonomic homeostasis plays a considerable role. Key words: blood loss, postresuscitative period, behavior, laser, posthypoxic encephalopathy, norepinephrine.

    Correctional officers (COs) are exposed to various factors likely to jeopardize their health and safety. Even if numerous studies have been focused on work-related stress among COs, few studies have been carried out in Italy. Indentify the work-related factors and comprehend how they negatively affect the COs' psychological health in the Italian penal system. A qualitative approach was employed. Twenty-eight COs employed in a detention block of an Italian jail were interviewed face-to-face. For the analyses of the text, Template Analysis technique was followed. The analyses of the text highlighted six macro-categories and thirteen categories hierarchically linked to them: A) Intrinsic work-related factors with six categories: demanding contact with prisoners, high level of responsibility, health risks, critical events, lack of intellectual and social stimulation, and conflict value; B) Factors related to the type of contract and work organization: challenging working hours contrasted with social time, and relocation; C) Social factors: relationships with colleagues and hierarchy; D) Organizational factors: organizational injustice, E) External factors: negative social image; F) Physical environmental factors: physical structure of the prison building. The results indicated that COs are at high risk of stress. More specifically, the analyses highlighted that the most stressful part of the COs' job concerns their relationship with the inmates.

    Phase distortion exists in collected interferogram because of a variety of measure reasons when spatial heterodyne spectrometers are used in practice. So an improved phase correction method is presented. The phase curve of interferogram was obtained through Fourier inverse transform to extract single side transform spectrum, based on which, the phase distortions were attained by fitting phase slope, so were the phase correction functions, and the convolution was processed between transform spectrum and phase correction function to implement spectrum phase correction. The method was applied to phase correction of actually measured monochromatic spectrum and emulational water vapor spectrum. Experimental results show that the low-frequency false signals in monochromatic spectrum fringe would be eliminated effectively to increase the periodicity and the symmetry of interferogram, in addition when the continuous spectrum imposed phase error was corrected, the standard deviation between it and the original spectrum would be reduced form 0.47 to 0.20, and thus the accuracy of spectrum could be improved.

    This study investigates the association between political trust (an aspect of institutional trust) in the Riksdag (the national parliament in Sweden) and self-reported psychological health, taking generalized (horizontal) trust in other people into account. The 2004 public health survey in Skåne in Southern Sweden is a cross-sectional postal questionnaire study that was answered by 27,757 respondents aged 18-80 yielding a 59% response rate. A logistic regression model was used to investigate the associations between political trust and self-reported psychological health adjusting for possible confounders (age, country of origin, education, economic stress and generalized trust in other people i.e. horizontal trust). We found that 13.0% of the men and 18.9% of the women reported poor psychological health. A total of 17.3% and 11.6% of the male and female respondents, respectively, reported that they had no trust at all in the national parliament, and another 38.2% and 36.2%, respectively, reported that their political trust was not particularly high. Respondents in younger age groups, born abroad, with high education, high levels of economic stress, low horizontal trust and low political trust had significantly higher levels of self-reported poor psychological health. There was a significant association between low political trust and low horizontal trust. After adjustments for age, country of origin, education and economic stress, the inclusion of horizontal trust reduced the odds ratios of self-reported poor psychological health in the "no political trust at all" category compared to the "very high political trust" category from 1.6 to 1.4 among men and from 1.7 to 1.4 among women. It is concluded that low political trust in the Riksdag seems to be significantly and positively associated with poor mental health.

    Human activity and natural climate trends constitute a major threat to coral reefs worldwide. Models predict a significant reduction in reef spatial extension together with a decline in biodiversity in the relatively near future. In this context, monitoring programs to detect changes in reef ecosystems are essential. In recent years, coral reef mapping using remote sensing data has benefited from instruments with better resolution and computational advances in storage and processing capabilities. However, the water column represents an additional complexity when extracting information from submerged substrates by remote sensing that demands a correction of its effect. In this article, the basic concepts of bottom substrate remote sensing and water column interference are presented. A compendium of methodologies developed to reduce water column effects in coral ecosystems studied by remote sensing that include their salient features, advantages and drawbacks is provided. Finally, algorithms to retrieve the bottom reflectance are applied to simulated data and actual remote sensing imagery and their performance is compared. The available methods are not able to completely eliminate the water column effect, but they can minimize its influence. Choosing the best method depends on the marine environment, available input data and desired outcome or scientific application. PMID:25215941

    2017-03-01

    Effective obesity prevention requires a synergistic mix of population-level interventions including a strong role for government and the regulation of the marketing, labelling, content and pricing of energy-dense foods and beverages. In this paper we adopt the agenda of the Australian Federal Government (AFG) as a case study to understand the factors generating or hindering political priority for such 'regulatory interventions' between 1990 and 2011. Using a theoretically-guided process tracing method we undertook documentary analysis and conducted 27 interviews with a diversity of actors involved in obesity politics. The analysis was structured by a theoretical framework comprising four dimensions: the power of actors involved; the ideas the actors deploy to interpret and portray the issue; the institutional and political context; and issue characteristics. Despite two periods of sustained political attention, political priority for regulatory interventions did not emerge and was hindered by factors from all four dimensions. Within the public health community, limited cohesion among experts and advocacy groups hampered technical responses and collective action efforts. An initial focus on children (child obesity), framing the determinants of obesity as 'obesogenic environments', and the deployment of 'protecting kids', 'industry demonization' and 'economic costs' frames generated political attention. Institutional norms within government effectively selected out regulatory interventions from consideration. The 'productive power' and activities of the food and advertising industries presented formidable barriers, buttressed by a libertarian/neolibertarian rhetoric emphasizing individual responsibility, a negative view of freedom (as free from 'nanny-state' intervention) and the idea that regulation imposes an unacceptable cost on business. Issue complexity, the absence of a supportive evidence base and a strict 'evidence-based' policy-making approach were used as

    2007-10-13

    Why do some global health initiatives receive priority from international and national political leaders whereas others receive little attention? To analyse this question we propose a framework consisting of four categories: the strength of the actors involved in the initiative, the power of the ideas they use to portray the issue, the nature of the political contexts in which they operate, and characteristics of the issue itself. We apply this framework to the case of a global initiative to reduce maternal mortality, which was launched in 1987. We undertook archival research and interviewed people connected with the initiative, using a process-tracing method that is commonly employed in qualitative research. We report that despite two decades of effort the initiative remains in an early phase of development, hampered by difficulties in all these categories. However, the initiative's 20th year, 2007, presents opportunities to build political momentum. To generate political priority, advocates will need to address several challenges, including the creation of effective institutions to guide the initiative and the development of a public positioning of the issue to convince political leaders to act. We use the framework and case study to suggest areas for future research on the determinants of political priority for global health initiatives, which is a subject that has attracted much speculation but little scholarship.

    Full Text Available Performance appraisal politics are viewed as a vital human resource management issuewhere it consists of two salient features: motivational motive and punishment motive. The ability ofappraisers (e.g., immediate bosses/managers to properly implement such appraisal politics inallocating performance ratings may have significant impact on job satisfaction. Although the nature ofthis relationship is important, little is known about the role of performance appraisal politics as apredicting variable in the performance appraisal models. Therefore, this study was conducted toexamine the effect of performance appraisal politics on job satisfaction using 150 usablequestionnaires gathered from employees who have worked in a national postal company in Sarawak,Malaysia. In initial data analysis, the results of exploratory factor analysis confirmed that themeasurement scales used in this study satisfactorily met the standards of validity and reliabilityanalyses. Further, in hypothesis testing, the outcomes of stepwise regression analysis showed thatperformance appraisal politics (i.e., motivational motive and punishment motive significantlycorrelated with job satisfaction. Statistically, this result confirms that performance appraisal politicsact as important predictors of job satisfaction in the studied organization. In addition, discussion,implications and conclusion are elaborated.

    Full Text Available This case study examines the Walt Disney Company’s foray in the Chinese market from a political economic perspective. It focuses on two film-related events: 1 the 'Kundun' incident in 1996 that displays the ideological confrontation between Disney and China in the post-Cold War era, and 2 the production of 'Mulan 'in 1998 as both a political compromise and a strategic marketing decision for Disney to regain the Chinese market. The conflicts and negotiations between Disney and China provide a telling example to study the local operation of global capitalism, especially in terms of its interaction with the state. While many believe that the advent of globalization will open more free markets for fair competition, this study reveals how government policy intervenes in the global entertainment industry, and sheds light on the political and economic struggles behind the silver screen.

  14. Theorising Media, Power and Politics in Discourse Theory and Framing Studies

    DEFF Research Database (Denmark)

    Dindler, Camilla; Roslyng, Mette Marie

    The development of digital media has profound consequences for social and political interaction and, therefore, a new radical interactivity also influences the way in which media can be theorised and analysed? (Couldry, 2012, p. 2). As pointed out by Hall (2006) and others, media discourse may...... either contribute to or challenge the current status quo. Likewise, media framing studies indicate that the media may play an independent political role in terms of raising, shaping and morally judging issues of civic relevance (Entman, 2004). Framing and discourse theory have overlapping as well...... as different trajectories in empirical studies of mediated political communication. Both perspectives bear upon constructivist and critical thinking concerning the role of media in society (Gitlin 1980) and previous studies of media content have even sometimes conflated the terms discourse and frame...

    Unless a correction is made, population estimates derived from a sample of belt transects will be biased if a fraction of, the individuals on the sample transects are not counted. An approach, useful for correcting this bias when sampling immotile populations using transects of a fixed width, is presented. The method assumes that a searcher's ability to find objects near the center of the transect is nearly perfect. The method utilizes a mathematical equation, estimated from the data, to represent the searcher's inability to find all objects at increasing distances from the center of the transect. An example of the analysis of data, formation of the equation, and application is presented using waterfowl nesting data collected in Colorado.

  16. Positron annihilation lifetime spectroscopy source correction determination: A simulation study

    Positron annihilation lifetime spectroscopy (PALS) can provide sensitive detection and identification of vacancy-related point defects in materials. These measurements are normally performed using a positron source supported, and enclosed by, a thin foil. Annihilation events from this source arrangement must be quantified and are normally subtracted from the spectrum before analysis of the material lifetime components proceeds. Here simulated PALS spectra reproducing source correction evaluation experiments have been systematically fitted and analysed using the packages PALSfit and MELT. Simulations were performed assuming a single lifetime material, and for a material with two lifetime components. Source correction terms representing a directly deposited source and various foil supported sources were added. It is shown that in principle these source terms can be extracted from suitably designed experiments, but that fitting a number of independent, nominally identical, spectra is recommended.

    The goal of this work was the determination, using metrologic severity, the factors of correction for coincidences XX, Xγ and γγ and the factors of transference of efficiency for use in gamma spectrometry. On this way, it was carried through by determination of nuclear parameters of a nuclide used in medicine diagnostic ( 201 Tl) and the standardization of two environmental samples, of regular and irregular geometry, proceeding from the residual (ashes and slag) from the nuclear industry. The results shows that this adopted methodology is valid, and it allows its application for many different nuclides, including complex decay schema nuclides, using only photons spectrometry techniques on semiconductor detectors.

    Politics plays a critical role in agenda setting in health affairs; therefore, understanding the priorities of the political agenda in health is very important. The political priority for safe motherhood has been investigated at the national level in different countries. The objective of this study was to explore why and how maternal health became a political priority at sub-national level in the state of Madhya Pradesh in India. This study followed a qualitative design. Data were collected by carrying out interviews and review of documents. Semi-structured interviews were carried out with twenty respondents from four stakeholder groups: government officials, development partners, civil society and academics. Data analysis was performed using thematic analysis. The analysis was guided by Kingdon's multiple streams model. The emergence of maternal health as a political priority in Madhya Pradesh was the result of convergence in the developments in different streams: the development of problem definition, policy generation and political change. The factors which influenced this process were: emerging evidence of the high magnitude of maternal mortality, civil society's positioning of maternal mortality as a human rights violation, increasing media coverage, supportive policy environment and launch of the National Rural Health Mission (NRHM), the availability of effective policy solutions, India's aspiration of global leadership, international influence, maternal mortality becoming a hot debate topic and political transition at the national and state levels. Most of these factors first became important at national level which then cascaded to the state level. Currently, there is a supportive policy environment in the state for maternal health backed by greater political will and increased resources. However, malnutrition and population stabilization are the competing priorities which may push maternal health off the agenda. The influence of the events and factors

    Patient motion during dynamic PET studies is a well-documented source of errors. The purpose of this study was to investigate the incidence of frame-to-frame motion in dynamic 15 O-water myocardial perfusion PET studies, to test the efficacy of motion correction methods and to study whether implementation of motion correction would have an impact on the perfusion results. We developed a motion detection procedure using external radioactive skin markers and frame-to-frame alignment. To evaluate motion, marker coordinates inside the field of view were determined in each frame for each study. The highest number of frames with identical spatial coordinates during the study were defined as ''non-moved''. Movement was considered present if even one marker changed position, by one pixel/frame compared with reference, in one axis, and such frames were defined as ''moved''. We tested manual, in-house-developed motion correction software and an automatic motion correction using a rigid body point model implemented in MIPAV (Medical Image Processing, Analysis and Visualisation) software. After motion correction, remaining motion was re-analysed. Myocardial blood flow (MBF) values were calculated for both non-corrected and motion-corrected datasets. At rest, patient motion was found in 18% of the frames, but during pharmacological stress the fraction increased to 45% and during physical exercise it rose to 80%. Both motion correction algorithms significantly decreased (p<0.006) the number of moved frames and the amplitude of motion (p<0.04). Motion correction significantly increased MBF results during bicycle exercise (p<0.02). At rest or during adenosine infusion, the motion correction had no significant effects on MBF values. Significant motion is a common phenomenon in dynamic cardiac studies during adenosine infusion but especially during exercise. Applying motion correction for the data acquired during exercise clearly changed the MBF results, indicating that motion

    This research examined the interaction of organizational politics perceptions and employee age on job performance in 3 studies. On the basis of conservation of resources theory, the authors predicted that perceptions of politics would demonstrate their most detrimental effects on job performance for older workers. Results across the 3 studies provided strong support for the hypothesis that increases in politics perceptions are associated with decreases in job performance for older employees and that perceptions of politics do not affect younger employees' performance. Implications of these results, strengths and limitations, and directions for future research are discussed. Copyright 2005 APA, all rights reserved.

    2014-03-01

    In conventional digital radiography (DR) using a dual energy subtraction technique, a significant fraction of the detected photons are scattered within the body, resulting in the scatter component. Scattered radiation can significantly deteriorate image quality in diagnostic X-ray imaging systems. Various methods of scatter correction, including both measurement and non-measurement-based methods have been proposed in the past. Both methods can reduce scatter artifacts in images. However, non-measurement-based methods require a homogeneous object and have insufficient scatter component correction. Therefore, we employed a measurement-based method to correct for the scatter component of inhomogeneous objects from dual energy DR (DEDR) images. We performed a simulation study using a Monte Carlo simulation with a primary modulator, which is a measurement-based method for the DEDR system. The primary modulator, which has a checkerboard pattern, was used to modulate primary radiation. Cylindrical phantoms of variable size were used to quantify imaging performance. For scatter estimation, we used Discrete Fourier Transform filtering. The primary modulation method was evaluated using a cylindrical phantom in the DEDR system. The scatter components were accurately removed using a primary modulator. When the results acquired with scatter correction and without correction were compared, the average contrast-to-noise ratio (CNR) with the correction was 1.35 times higher than that obtained without correction, and the average root mean square error (RMSE) with the correction was 38.00% better than that without correction. In the subtraction study, the average CNR with correction was 2.04 (aluminum subtraction) and 1.38 (polymethyl methacrylate (PMMA) subtraction) times higher than that obtained without the correction. The analysis demonstrated the accuracy of scatter correction and the improvement of image quality using a primary modulator and showed the feasibility of

    Full Text Available The intention of this paper is to provide a historical overview and an introduction to the interviews with Bodgan Osolnik, Breda Pavlič, Cees Hamelink, Daya K. Thussu, Peter Golding and Dan Hind presented in this special section. Following Marx, we entitled the section The Point Is to Change It! Critical Political Interventions in Media and Communication Studies. We discuss the need for critical theory to bridge the divide between theory and practice because this notion is central to all of the interviews in one way or another. We also provide a historical contextualization of important theoretical as well as political developments in the 1970s and 1980s. This period may be seen as a watershed era for the critical political economy of communication and for the political articulation of demands for a widespread transformation and democratization in the form of the New World Information and Communication Order initiative. We believe that many contemporary issues have a long history, with their roots firmly based in this era. The historical perspective therefore cannot be seen as nostalgia, but as an attempt to understand the historical relations of power and how they have changed and shifted. In our view, the historical perspective is crucial not only for understanding long-lasting historical trends, but also to remind ourselves that the world is malleable, and to keep alive the promises of the progressive struggles of the past.

    Full Text Available This article analyzes the association between political finance and electoral performance in the 2010 Brazilian elections for state and federal deputies. It also investigates the interaction effect of incumbency and gender on this association. We conclude: (i there is a positive and statistically significant association between political finance and electoral performance, yet the intensity of this association varies according to the type of candidate; (ii the association is stronger for challengers than for incumbents – thus extending the "Jacobson effect" to the Brazilian case; and (iii the association is stronger for women than for men – which suggests an extension of the idea underlying the "Jacobson effect". The association between finance and electoral performance tends to be stronger for candidates facing electoral disadvantages, whether these stem from limited political capital, gender discrimination, or any other factor not studied here resulting in a similar effect. Political finance works as a tool that, to some extent, may counteract the negative effect of such factors on electoral performance.

  3. A simulation study of linear coupling effects and their correction in RHIC

    1992-11-01

    This paper describes a possible skew quadrupole correction system for linear coupling for the RHIC92 lattice. A simulation study has been done for the correction system. Results are given for the performance of the correction system, and the required strength of the skew quadruple correctors. An important effect of linear coupling in RHIC is to shift the tune ν x ν y , sometimes called tune splitting. Most of this tune splitting can be corrected with a two family skew quadrupole correction system. For RHIC92, the same 2 family correction system will work for all likely choices of β*. This was not the case for the RHIC91 lattice where different families of correctors were needed for different β*. The tune splitting described above which is corrected with a 2 family correction system is driven primarily by the ν x - ν y harmonic of the skew quadrupole field given by the field multipole αl. There are several other effects of linear coupling present which are driven primarily by the ν x + ν y harmonics of the skew quadrupole field, αl. These include the following: (1) A higher order residual tune shift that remains after correction with the 2 family correction system. This tune shift is roughly quadratic in αl; (2) Possible large changes in the beta functions; (3) Possible increase in the beam size at injection due to the beta function distortion and the emittance distortion at injection

    The true coincidence correction in measuring filter samples has been studied by high efficiency HPGe gamma detectors. The true coincidence correction for a specific three excited levels de-excitation case has been analyzed, and the typical analytical expressions of true coincidence correction factors have been given. According to the measured relative efficiency on the detector surface with 8 'single' energy gamma emitters and efficiency of filter samples, the peak and total efficiency surfaces are fitted. The true coincidence correction factors of sup 6 sup 0 Co and sup 1 sup 5 sup 2 Eu calculated by the efficiency surfaces agree well with experimental results

    Full Text Available Abstract Background This study aimed to examine the longitudinal contributions of four political and socioeconomic factors to the increase in life expectancy in less developed countries (LDCs between 1970 and 2004. Methods We collected 35 years of annual data for 119 LDCs on life expectancy at birth and on four key socioeconomic indicators: economy, measured by log10 gross domestic product per capita at purchasing power parity; educational environment, measured by the literacy rate of the adult population aged 15 years and over; nutritional status, measured by the proportion of undernourished people in the population; and political regime, measured by the regime score from the Polity IV database. Using linear mixed models, we analyzed the longitudinal effects of these multiple factors on life expectancy at birth with a lag of 0-10 years, adjusting for both time and regional correlations. Results The LDCs' increases in life expectancy over time were associated with all four factors. Political regime had the least influence on increased life expectancy to begin with, but became significant starting in the 3rd year and continued to increase, while the impact of the other socioeconomic factors began strong but continually decreased over time. The combined effects of these four socioeconomic and political determinants contributed 54.74% - 98.16% of the life expectancy gains throughout the lag periods of 0-10 years. Conclusions Though the effect of democratic politics on increasing life expectancy was relatively small in the short term when compared to the effects of the other socioeconomic factors, the long-term impact of democracy should not be underestimated.

Furthermore, we study the topics that are associated with the co-occurrence of two politicians in the same tweet. We cannot conclude, from a simple statistical analysis of tweet volume and their time evolution, that it is possible to precisely predict the election outcome (or at least not in our case of study that was characterized by a "too-close-to-call" scenario). On the other hand, we found that the volume of tweets and their change in time provide a very good proxy of the final results. We present this analysis both at a national level and at smaller levels, ranging from the regions composing the country to macro-areas (North, Center, South).

  16. Trends in Addressing Social Needs: A Longitudinal Study of Congregation-Based Service Provision and Political Participation

    Full Text Available When congregations seek to address social needs, they often pursue this goal through acts of service and political engagement. Over the past three decades, a tremendous amount of research has been dedicated to analyzing congregation-based service provision and political participation. However, little is known about how congregations’ involvement in these arenas has changed during this period. To help fill this gap, this study analyzes three waves of data from a national survey of congregations to assess how congregations’ participation patterns in service-related and political activities have been changing since the 1990s. It also examines trends among subpopulations of congregations grouped by their religious tradition, ethnoracial composition, and ideological orientation. Overall, this study finds that among most types of congregations, the percentage participating in service-related activities is substantial and increasing, while the percentage participating in political activities is less substantial and decreasing. This decline in political participation has implications for the role congregations play in addressing social needs. Relieving immediate needs through service provision without also pursuing long-term solutions through political participation can limit congregations’ ability to comprehensively address social needs. Among the few types of congregations that have high and/or increasing participation rates in both service-related and political activities are Catholic, predominantly Hispanic, and politically liberal congregations.

    Full Text Available This article studies the focus studies of geographically connected and geographically not connected countries, i.e. regional and comparative regional studies. In the first part of the article, a description of the role and development of this type of studies as a subdiscipline of comparative politics is provided. In the second part, I present the results of quantitative analysis of the content of articles published in the academic journals published or co-published by the Faculty of Political Science, University of Zagreb. The objects of analysis are regional studies of South-East Europe published in the journals. The main goal of this article is to determine which countries in their regional surroundings are researched the most by Croatian political scientists (and other authors who publish such articles in Croatian or English language in those journals, and which countries Croatia is most often compared to. This research has shown that, with regard to studies of the region, Croatian political scientists mostly focus on the countries of the former Yugoslavia.

  18. Virtually Impossible: Deleuze and Derrida on the Political Problem of Islands (and Island Studies

    Directory of Open Access Journals (Sweden)

    Stewart Williams

    2012-11-01

    Full Text Available It is commonplace to think of an island as a discreetly bounded unit. Selected writings on islands by the poststructuralist philosophers Gilles Deleuze and Jacques Derrida reveal the island variously to be both real and imaginary, mythological and scientific, but as most problematic when constituted in political terms as an indivisible, sovereign entity. These two thinkers’ more broadly developed concepts of the virtual and the impossible, respectively, are seen to disrupt any assumptions about the fixity and closure of the island polity. Instead they emphasize its actualization through processual relations that can be difficult yet dynamic and decisive in effecting the move from being to becoming-other. As the possibilities for instituting more ethical as well as different political relations open up, the question of island studies remaining in its currently coherent, familiar form is raised for consideration.

  19. Political Regime and Learning Outcomes of Stakeholder Participation: Cross-National Study of 81 Biosphere Reserves

    Directory of Open Access Journals (Sweden)

    Alba Mohedano Roldán

    2017-04-01

    Full Text Available Stakeholder participation in natural resource management has spread widely, even to nondemocracies, driven by expectations of beneficial outcomes such as multidirectional learning. However, can we expect participation to be equally effective in achieving multidirectional learning in democracies and nondemocracies? Unsurprisingly, previous studies indicate the relevance of power distribution for learning. Higher levels of repression and accumulation of political capital in nondemocracies should limit the distribution of power across stakeholders. Yet, the relationship between political regime, participation, and learning has rarely been studied empirically. I address this gap by analysing multidirectional learning in stakeholder participation in 81 Man and the Biosphere reserves across 35 countries using ordinary least squares regression, Firth logistic regression, and heat maps. The results suggest that the amount of stakeholders sharing knowledge and learning is similar in both regimes. However, a closer analysis reveals differences in the impact different stakeholders have on the learning process. More concretely, local actors share knowledge more often and have a greater impact on stakeholders’ learning in democracies, while state actors display similar behavior across regimes in terms of learning and sharing knowledge. Thus, although there are notable similarities across regimes, multidirectional learning through stakeholder participation is influenced by the political context.

As a method of achieving those faculty members "Simple randomized (random sampling" is used. The psychometric properties of the Turkish version of Perception of Organizational Politics Scale showed that the scale has a satisfactory level of reliability and validity for the Turkish employee sample.

  1. A Conceptual Shift in Studies of Belonging and the Politics of Belonging

    Directory of Open Access Journals (Sweden)

    Eva Youkhana

    2015-07-01

    Full Text Available The study of belonging, its underlying notions, and the politics of belonging shows that social, political, and territorial demarcations are still based on essentialist conceptions of the collective. These are often applied and reproduced in the social sciences as a result of methodological nationalism. Space-sensitive studies of migration and globalization and a return to the material have recently challenged social constructivist lines of argumentation and have provoked a conceptual shift from analytical categories with inherent spatiality, territoriality, and boundary marking to concepts based on movement and flow. In this paper the analysis of belonging and the related politics of belonging in migration studies incorporates space as an analytical category that cross-cuts established categorizations such as race, class, gender, and stage in the life cycle, and integrates a material semiotic perspective more systematically into the study of social relations at the intersection of the social categories mentioned. A new concept of belonging is defined which reflects the complex relations that individuals have with other people, circulating objects, artefacts, and changing social, political, and cultural landscapes, thus mirroring both the material conditions and the underlying power relations. Such an understanding of belonging proceeds from social naturalizations and fixations to the multiplicity and situatedness of individual attachments, which entangle social, imagined, and sensual-material relations that are constantly re-articulated and re-negotiated by actors in their day-to-day practices. In such a reading, belonging comes into being as a result of individual life stories, versatile contexts, and situated experiences and acts. In times of constant exchange through travel, mass media, and communication technologies, the conceptualization of belonging questions established sociocultural and political demarcations, indicates the

    Here we introduce the Genetic and Environmental Foundations of Political and Economic Behaviors: A Panel Study of Twins and Families (PIs Alford, Hatemi, Hibbing, Martin, and Smith). This study was designed to explore the genetic and environmental influences on social, economic, and political behaviors and attitudes. It involves identifying the psychological mechanisms that operate on these traits, the heritability of complex economic and political traits under varying conditions, and specific genetic correlates of attitudes and behaviors. In addition to describing the study, we conduct novel analyses on the data, estimating the heritability of two traits so far unexplored in the extant literature: Machiavellianism and Baron-Cohen's Empathizing Quotient.

Correlation coefficient values in the last four cells of column 6 were misplaced with correlation coefficient values in the last four cells of column 7. All versions of this article have been corrected.] We conduct a theory-driven empirical investigation on whether political behavior, as a coping strategy to perceived organizational politics, creates resource trade-offs in moderating the relationship between perceived organizational politics and task performance. Drawing on conservation of resources theory, we hypothesize that political behavior mitigates the adverse effect of perceived organizational politics on task performance via psychological empowerment, yet exacerbates its adverse effect on task performance via emotional exhaustion. Three-wave multisource data from a sample of 222 employees and their 75 supervisors were collected for hypothesis testing. Findings supported our hypotheses. Our study enhances understandings of the complex resource dynamics of using political behavior to cope with perceived organizational politics and highlights the need to move stress-coping research from a focus on the stress-buffering effect of coping on outcomes to a focus on the underlying competing resource dynamics.

    Wesley Soares de Melo

    Full Text Available ABSTRACT Objective: To build and validate a guide of attributes of the nurse's political competence. Method: Methodological research. This study comprised the construction of the instrument through literature review; experts validation of pre-established attributes for composing the guide; and clinical validation in the nurses work environment/reality. The data collection took place in the months from August to October 2014, and the analysis was based on the content analysis of Bardin and use of Epi info 3.5. All ethical precepts have been complied with. Results: From 29 attributes found in the literature, 25 have been validated by experts. Clinical/practical validation involved the participation of 43 nurses, who observed that the attributes are not articulated with the professional practices developed by them. Conclusion: The attributes of the nurse's political competence were identified with support of literature. It is concluded that the professionals still have limited and fragmented perception of political competence, expressing difficulty/limitation.

  5. A biased review of biases in Twitter studies on political collective action

    Cihon, Peter; Yasseri, Taha

    2016-08-01

    In recent years researchers have gravitated to Twitter and other social media platforms as fertile ground for empirical analysis of social phenomena. Social media provides researchers access to trace data of interactions and discourse that once went unrecorded in the offline world. Researchers have sought to use these data to explain social phenomena both particular to social media and applicable to the broader social world. This paper offers a minireview of Twitter-based research on political crowd behaviour. This literature offers insight into particular social phenomena on Twitter, but often fails to use standardized methods that permit interpretation beyond individual studies. Moreover, the literature fails to ground methodologies and results in social or political theory, divorcing empirical research from the theory needed to interpret it. Rather, investigations focus primarily on methodological innovations for social media analyses, but these too often fail to sufficiently demonstrate the validity of such methodologies. This minireview considers a small number of selected papers; we analyse their (often lack of) theoretical approaches, review their methodological innovations, and offer suggestions as to the relevance of their results for political scientists and sociologists.

    Full Text Available Freedom of speech or expression is an indication of a democratic country. Indonesia that has transformed itself from an authoritarian government during the New Order Era into a democratic country in the so called Reform Era. This study is an attempt to find out the existence of freedom of expression in the Indonesian printed media. The data were collected from the Jakarta Post Readers’Forum from 1 November 2010 to 28 February 2011. The data were then classified and analysed based on Brown and Levinson’s theory of politeness strategies. The data analysis shows that a lot of utterances can be classified under Politeness Strategy 1 (the least polite strategy out of the four strategies. This proves that people are now free to express their ideas and criticisms in the most direct manner without fear of being arrested or reprimanded by the government. Even the sensitive issues like SARA (Ethnic, Religion, Racial and Communal conflicts can be freely discussed in the printed media. Thus freedom of expression is prevailing in Indonesia under the New Era government.

    Purpose: To investigate the effect of lung density corrections on the dose delivered to lung cancer radiotherapy patients in a multi-institutional clinical trial, and to determine whether commonly available density-correction algorithms are sufficient to improve the accuracy and precision of dose calculation in the clinical trials setting. Methods and Materials: A benchmark problem was designed (and a corresponding phantom fabricated) to test density-correction algorithms under standard conditions for photon beams ranging from 60 Co to 24 MV. Point doses and isodose distributions submitted for a Phase III trial in regionally advanced, unresectable non-small-cell lung cancer (Radiation Therapy Oncology Group 88-08) were calculated with and without density correction. Tumor doses were analyzed for 322 patients and 1236 separate fields. Results: For the benchmark problem studied here, the overall correction factor for a four-field treatment varied significantly with energy, ranging from 1.14 ( 60 Co) to 1.05 (24 MV) for measured doses, or 1.17 ( 60 Co) to 1.05 (24 MV) for doses calculated by conventional density-correction algorithms. For the patient data, overall correction factors (calculated) ranged from 0.95 to 1.28, with a mean of 1.05 and distributional standard deviation of 0.05. The largest corrections were for lateral fields, with a mean correction factor of 1.11 and standard deviation of 0.08. Conclusions: Lung inhomogeneities can lead to significant variations in delivered dose between patients treated in a clinical trial. Existing density-correction algorithms are accurate enough to significantly reduce these variations

    In conventional digital radiography (DR) using a dual energy subtraction technique, a significant fraction of the detected photons are scattered within the body, making up the scatter component. Scattered radiation can significantly deteriorate image quality in diagnostic X-ray imaging systems. Various methods of scatter correction, including both measurement- and non-measurement-based methods, have been proposed in the past. Both methods can reduce scatter artifacts in images. However, non-measurement-based methods require a homogeneous object and have insufficient scatter component correction. Therefore, we employed a measurement-based method to correct for the scatter component of inhomogeneous objects from dual energy DR (DEDR) images. We performed a simulation study using a Monte Carlo simulation with a primary modulator, which is a measurement-based method for the DEDR system. The primary modulator, which has a checkerboard pattern, was used to modulate the primary radiation. Cylindrical phantoms of variable size were used to quantify the imaging performance. For scatter estimates, we used discrete Fourier transform filtering, e.g., a Gaussian low-high pass filter with a cut-off frequency. The primary modulation method was evaluated using a cylindrical phantom in the DEDR system. The scatter components were accurately removed using a primary modulator. When the results acquired with scatter correction and without scatter correction were compared, the average contrast-to-noise ratio (CNR) with the correction was 1.35 times higher than that obtained without the correction, and the average root mean square error (RMSE) with the correction was 38.00% better than that without the correction. In the subtraction study, the average CNR with the correction was 2.04 (aluminum subtraction) and 1.38 (polymethyl methacrylate (PMMA) subtraction) times higher than that obtained without the correction. The analysis demonstrated the accuracy of the scatter correction and the

    We discuss the effect of catchment area nonresidency on estimates of cancer incidence from a tumor-registry-based cohort study and demonstrate that a relatively simple correction is possible in the context of Poisson regression analysis if individual residency histories or the probabilities of residency are known. A comparison of a complete data maximum likelihood analysis with several Poisson regression analyses demonstrates the adequacy of the simple correction in a large simulated data set. We compare analyses of stomach-cancer incidence from the Radiation Effects Research Foundation tumor registry with and without the correction. We also discuss some implications of including cases identified only on the basis of death certificates. (author)

    We study theoretically and empirically whether natural resource windfalls affect political regimes. We document the following regularities. Natural resource windfalls have no effect on the political system when they occur in democracies. However, windfalls have significant political consequences in autocracies. In particular, when an autocratic country receives a positive shock to its flow of resource rents it responds by becoming even more autocratic. Furthermore, there is heterogeneity in t...

  15. Politeness, emotion, and gender: A sociophonetic study of voice pitch modulation

    Science.gov (United States)

    Yuasa, Ikuko

    The present dissertation is a cross-gender and cross-cultural sociophonetic exploration of voice pitch characteristics utilizing speech data derived from Japanese and American speakers in natural conversations. The roles of voice pitch modulation in terms of the concepts of politeness and emotion as they pertain to culture and gender will be investigated herein. The research interprets the significance of my findings based on the acoustic measurements of speech data as they are presented in the ERB-rate scale (the most appropriate scale for human speech perception). The investigation reveals that pitch range modulation displayed by Japanese informants in two types of conversations is closely linked to types of politeness adopted by those informants. The degree of the informants' emotional involvement and expressions reflected in differing pitch range widths plays an important role in determining the relationship between pitch range modulation and politeness. The study further correlates the Japanese cultural concept of enryo ("self-restraint") with this phenomenon. When median values were examined, male and female pitch ranges across cultures did not conspicuously differ. However, sporadically occurring women's pitch characteristics which culturally differ in width and height of pitch ranges may create an 'emotional' perception of women's speech style. The salience of these pitch characteristics appears to be the source of the stereotypically linked sound of women's speech being identified as 'swoopy' or 'shrill' and thus 'emotional'. Such women's salient voice characteristics are interpreted in light of camaraderie/positive politeness. Women's use of conspicuous paralinguistic features helps to create an atmosphere of camaraderie. These voice pitch characteristics promote the establishment of a sense of camaraderie since they act to emphasize such feelings as concern, support, and comfort towards addressees, Moreover, men's wide pitch ranges are discussed in view

    2012-01-01

    The motion of the head during brain positron emission tomography (PET) acquisitions has been identified as a source of artifact in the reconstructed image. In this study, a method is described to develop an image-based motion correction technique for correcting the post-acquisition data without using external optical motion-tracking system such as POLARIS. In this technique, GATE has been used to simulate PET brain scan using point sources mounted around the head to accurately monitor the position of the head during the time frames. The measurement of head motion in each frame showed a transformation in the image frame matrix, resulting in a fully corrected data set. Using different kinds of phantoms and motions, the accuracy of the correction method is tested and its applicability to experimental studies is demonstrated as well.

    2010-01-01

    Full Text Available The article is dealing with the issue of political support in Croatia, related to the issues of trust and legitimacy towards authority and institutions, as the elements of the political system. Previous research conducted in Croatia evidences a relatively low level of trust in the political authorities and institutions. In this paper we go by Easton’s dimensions of political support: authority support, support to institutions, support to democracy and support to community. All these forms of political support represent the subjective orientations of citizens towards the units of the political system. On the other hand, orientation and relationship of citizens towards the units of the political systems poses the question of citizenship. The paper is exploring the relation of subjective orientations of citizens towards the political systems units and different dimensions of political support in the specific context of Adriatic regions of Croatia, on the basis of the established models of citizenship developed by various authors. The results point out that the level of support rises as we go from the lower, specific types of support (support to authorities and support to institutions towards higher, diffuse modes of support (support to community. In the background of the political support, especially “support to democracy”, there are performances of the political system. In other words, political support is more instrumentally then intrinsically founded.

    2018-01-18

    Americans' confidence in science varies based on their political ideology. This ideological divide has potentially important effects on citizens' engagement with and participation in clinical studies of Alzheimer disease (AD). A probability sample of 1583 Americans was surveyed about their willingness to participate in longitudinal AD research and about their political attitudes. These survey results were compared with a survey of 382 participants in a longitudinal AD study at the Knight Alzheimer Disease Research Center. Among Americans, more conservative ideology decreases willingness to participate in a hypothetical longitudinal cohort study of AD both directly and through its negative effect on confidence in science. The Knight Alzheimer Disease Research Center study participants expressed more liberal ideology and greater confidence in science than Americans in general. Of the survey respondents opposed to participation, over a quarter changed to neutral or positive if the study returned their research results to them. Clinical studies of AD are likely biased toward participants who are more liberal and have higher confidence in science than the general population. This recruitment bias may be reduced by lowering the trust demanded of participants through measures such as returning research results to participants.

    The Kingdon model, based on the convergence of three streams (problem, policy, and politics) and the opening of a policy window, analyses the process by which a health issue is placed on the political agenda. We used this model to document the political agenda-setting process of the newborn hearing screening programme in Belgium. A qualitative study based on a document review and on semi-directed interviews was carried out. The interviews were conducted with nine people who had played a role in putting the issue in question on the political agenda, and the documents reviewed included scientific literature and internal reports and publications from the newborn hearing screening programme. The thematic analysis of the data collected was carried out on the basis of the Kingdon model's three streams. The political agenda-setting of this screening programme was based on many factors. The problem stream included factors external to the context under study, such as the technological developments and the contribution of the scientific literature which led to the recommendation to provide newborn hearing screening. The two other streams (policy and politics) covered factors internal to the Belgian context. The fact that it was locally feasible with financial support, the network of doctors convinced of the need for newborn hearing screening, the drafting of various proposals, and the search for financing were all part of the policy stream. The Belgian political context and the policy opportunities concerning preventive medicine were identified as significant factors in the third stream. When these three streams converged, a policy window opened, allowing newborn hearing screening onto the political agenda and enabling the policy decision for its introduction. The advantage of applying the Kingdon model in our approach was the ability to demonstrate the political agenda-setting process, using the three streams. This made it possible to identify the many factors involved in

    Full Text Available Today, in many countries of the world, in some cases women are barred from interfering in politics and social roles. Thus, still it is necessary to place women in political, social, economic and cultural activities. The purpose of this study is to examine individual and family barriers to women's political and social participation of the Shirez District in the city of Harsin. The research methodology used is descriptive-correlation and it is carried out by using a survey. The statistical population included the women older than 6 years in the Shirez District. A sample size of 333 person was determined by using the Kerejcie and Morgan table. They have been selected using the convenience sampling method with proportional assignment. Data analysis was done by using the Spearman coefficient and multiple regression analysis. The results showed that the political participation of women is in the medium level and their social participation is in the high level. Also, the results indicated that women believe that they are not able to participate in political affairs. The inability to communicate with others, the physical weakness and other problems, high volume of activities of women at home, high volume of activities in the agricultural sector and livestock, accepting dominance, lack of experience in political and administrative affairs and unwillingness of women compared to men in management are the main barriers of the political and social participation of rural women.

  5. Ezekiel and the politics of Yahweh : a study in the kingship of God

    OpenAIRE

    Bechtel, Christopher Ronald

    2012-01-01

    The book of Ezekiel, like much of the Hebrew Bible, depicts Yahweh as a king. However, Ezekiel’s presentation of Yahweh’s kingship has been largely ignored by modern scholarship, and, when it has been addressed, has been categorized as a grand metaphor for Yahweh’s divine superiority. In contrast, this study argues that Yahweh’s kingship is a genuine political force, not merely a cipher for the exalted status of Israel’s deity. To answer the objection that ‘Yahweh is king’ i...

    2009-07-01

    To investigate the associations between vertical (institutional) political trust in the Riksdag and daily smoking and smoking cessation. Cross-sectional study. In total, 27,757 individuals aged 18-80 years answered a postal questionnaire, which represents 59% of the random sample. A logistic regression model was used to investigate the associations between political trust in the Riksdag and daily smoking and smoking cessation. A multivariate analysis was performed to investigate the importance of possible confounders on the differences in daily smoking and smoking cessation according to political trust. In total, 14.9% of the men and 18.1% of the women were daily smokers. Middle-aged respondents were significantly more likely to be daily smokers than the young. The proportion of ever smokers who had quit smoking increased with age. Respondents with low generalized trust in other people [odds ratio (OR) 1.6, 95% confidence interval (CI) 1.5-1.8 among men; OR 1.7, 95% CI 1.5-1.8 among women] and not high political trust/no political trust at all (OR 1.6, 95% CI 1.4-1.8 among men; OR 1.8, 95% CI 1.6-2.0 among women) had significantly higher ORs of daily smoking. Men and women with not particularly high political trust/no political trust at all and no opinion of the Riksdag had significantly lower ORs of smoking cessation than people with very high/high political trust. These associations remained significant after multiple adjustments. The results suggest that political trust is independently associated with both daily smoking and smoking cessation.

    Increasing demands for luminosity in existing and future colliders have made lattice design and error tolerance and correction critical to achieving performance goals. The current state of the Tevatron collider is an example, with a strong skew quadrupole error present in the operational lattice. This work studies the high-order performance of the Tevatron and the strong nonlinear behavior introduced when a significant skew quadrupole error is combined with conventional sextupole correction, a behavior still clearly evident after optimal tuning of available skew quadrupole circuits. An optimization study is performed using different skew quadrupole families, and, importantly, local and global correction of the linear skew terms in maps generated by the code COSY INFINITY [M. Berz, COSY INFINITY version 8.1 user's guide and reference manual, Department of Physics and Astronomy MSUHEP-20704, Michigan State University (2002). URL http://cosy.pa.msu.edu/cosymanu/index.html]. Two correction schemes with one family locally correcting each arc and eight independent correctors in the straight sections for global correction are proposed and shown to dramatically improve linearity and performance of the baseline Tevatron lattice

  10. Summary Authoritarialism as Political Regime: Analysis of Historical and Empirical Studies

    Directory of Open Access Journals (Sweden)

    O. D. Grossman

    2016-01-01

    Full Text Available This article is devoted to the problems of existence of authoritarian regimes. The ambiguity of the resulting data determines the importance of the considered research. Authoritarianism is quite complicated socio-political phenomenon. For this reason, there are a lot of typologies and special features of authoritarianism as a political regime. Authoritarianism is not only a political regime, but it is also a set of social and political characteristics. Some countries, where the authoritarian tendencies dominate, are economically developed, and they have a competitive economy, but other countries, which are steeped in a reactionary authoritarian, do not develop properly. From the materials of this article it should be concluded that the political regime in Russia is principally authoritarian, or to be specific it is liberal authoritarian regime. This political regime has been established for the whole history of our country, and it is supported by paternalistic political culture and special mindset our nation.

    2015-05-01

    Ecological and cross-sectional studies have indicated that conservative political ideology is associated with better health. Longitudinal analyses of mortality are needed because subjective assessments of ideology may confound subjective assessments of health, particularly in cross-sectional analyses. Data were derived from the 2008 General Social Survey-National Death Index data set. Cox proportional analysis models were used to determine whether political party affiliation or political ideology was associated with time to death. Also, we attempted to identify whether self-reported happiness and self-rated health acted as mediators between political beliefs and time to death. In this analysis of 32,830 participants and a total follow-up time of 498,845 person-years, we find that political party affiliation and political ideology are associated with mortality. However, with the exception of independents (adjusted HR (AHR)=0.93, 95% CI 0.90 to 0.97), political party differences are explained by the participants' underlying sociodemographic characteristics. With respect to ideology, conservatives (AHR=1.06, 95% CI 1.01 to 1.12) and moderates (AHR=1.06, 95% CI 1.01 to 1.11) are at greater risk for mortality during follow-up than liberals. Political party affiliation and political ideology appear to be different predictors of mortality. Published by the BMJ Publishing Group Limited.

  12. Constructing Perceptions of Climate Change: a case study of regional political decision makers

    Bray, D.

    2012-12-01

    This case study of climate change communications assesses the salient means of communication and the message adopted by regional political decision makers on the German Baltic coast. Realizing that cultural factors and local values (and not simply knowledge) are significant influences in explaining attitudes towards climate change, this analysis draws from the records of regional weather, from scientists with a specific focus on the region, from the political decision makers for that region, and the media message reaching the decision makers, ensuring all elements of the analysis are drawn from the same socioeconomic, geophysical, political and cultural context. This is important as the social dynamics surrounding the trust in science is of critical importance and, as such, all elements of the case study are specifically contained within a common context. If the utility of climate change knowledge is to prompt well conceived adaptation/mitigation strategies then the political decision process, or at least the perceptions shaping it, can best be understood by locating it within the world view of the decision makers involved in the production process. Using the results of two survey questionnaires, one of regional climate scientists and one of regional political decision makers, ten years of local weather records, and a summary of the message from mass media circulation, the discord in perceptions of regional climate change are quantitatively explored. The conclusions drawn from the analysis include, compared to the scientific assessment: The decision makers' perceptions of recent past differ from actual observations. The decision makers' perceptions of the future differ from scientific assessments. The decision makers tend to over estimate the magnitude of regional climate change and its impacts. The decision makers tend to over estimate the sense of immediacy for adaptation measures. The conclusions drawn suggest that in the regional political realm, it is often a

    International Nuclear Information System (INIS)

    Nord, Lars; Stur, Elisabeth

    2010-11-01

    The overall purpose of this paper is to investigate how the premises for the political decision processes in the issue of final disposal of the Swedish nuclear waste are affected by changes in the public opinion climate and global events. The paper therefore focuses on questions concerning how the national political debate leading up to decisions interacts with the media debate, and the public opinion dynamic that arises when the two debates relate to each other. Particular interest is devoted to the arguments and standpoints that occur in politics and media and how they refer to the prevailing public opinion situation and to conditions in the surrounding world of a political, legal, economic, ecological and technological nature. An analysis of the arenas and actors involved in the debates ought to provide valuable knowledge regarding how the political agenda has been formed at different points in time. The following questions are of central interest to the study: - What characterizes the parliamentary and the party political debate in the nuclear waste issue, and in what way have actors, standpoints and arguments changed over time? - What characterizes opinion formation and news reporting in the media in the nuclear waste issue and in what way have actors, standpoints and arguments changed over time? The course of the debate at four different times and in connection with four parliamentary elections during the period 1976-2009 is analyzed in the study. The subject of the analysis includes the four parliamentary parties the Centre Party, the Liberal Party, the Moderates and the Social Democrats. These four parties have been chosen because they have been represented in the Swedish Parliament during the entire period studied and are therefore reasonable to compare. The study has mainly been conducted as a qualitative textual analysis of public print, party documents and media content. The qualitative text analysis is complemented to some extent by other existing

  17. Modeling time-series count data: the unique challenges facing political communication studies.

    Fogarty, Brian J; Monogan, James E

    2014-05-01

    This paper demonstrates the importance of proper model specification when analyzing time-series count data in political communication studies. It is common for scholars of media and politics to investigate counts of coverage of an issue as it evolves over time. Many scholars rightly consider the issues of time dependence and dynamic causality to be the most important when crafting a model. However, to ignore the count features of the outcome variable overlooks an important feature of the data. This is particularly the case when modeling data with a low number of counts. In this paper, we argue that the Poisson autoregressive model (Brandt and Williams, 2001) accurately meets the needs of many media studies. We replicate the analyses of Flemming et al. (1997), Peake and Eshbaugh-Soha (2008), and Ura (2009) and demonstrate that models missing some of the assumptions of the Poisson autoregressive model often yield invalid inferences. We also demonstrate that the effect of any of these models can be illustrated dynamically with estimates of uncertainty through a simulation procedure. The paper concludes with implications of these findings for the practical researcher. Copyright © 2013 Elsevier Inc. All rights reserved.

    2014-01-01

    Full Text Available His article deals with political dialogue as the basis of the progressive development of interstate cooperation and one of the few ways to diminish interstate tensions without use of military force. With the growing list of new threats and challenges it is very important to work out an effective mechanism of interstate cooperation and to use it in foreign policy. Political dialogue helps to form the basis for cooperation between states to ensure the security, political and socio-economic stability of countries. Moreover, the political dialogue in its various forms is no longer a seldom-used private practice. It is the "all-encompassing reality" now the study of which is necessary for understanding of the social, economic, and humanitarian phenomena in the international relations. The author analyzes principles, functions, rules of constructive interstate dialogue, reflects the conditions of the development of a true political dialogue and reveals the situation of its "stylization" The provisions presented in this article are presented from the viewpoint of practical use in the development of a constructive foreign policy. At the same time the author points to their philosophical basis, identifies regularities and characteristics from the standpoint of philosophical knowledge. As a practical demonstration of carrying on the political dialogue the article presents a brief description of Russian-German political relations at the present stage. Bilateral relations between these two countries, based on the rich history, consilience of main positions in resolving of international problems, largely reflect the basic terms and principles of a competent political dialogue.

  4. Putting politics into perspective. A Study of the Implementation of EU public utilities directives

    International Nuclear Information System (INIS)

    Berglund, S.K.

    2009-01-01

    In the area of public utilities, the member states of the European Union (EU) have agreed on ambitious policies to open up markets for competition and to regulate these markets. To have the expected effect, these policies have to be implemented effectively. In this book it is demonstrated that this is problematic; difficulties appear already in the first step of transposing the directives into national legislation. The analysis of an original quantitative data set including all public utilities directives and their transposition in five member states - the Netherlands, Germany, the United Kingdom, Spain, and Greece - shows that almost two thirds of all cases are transposed after the deadlines that are included in the directives. In order to explain problems with the implementation of EU policies, three main types of variables are used in the literature, namely political, administrative, and institutional variables. In recent literature on transposition the focus is on political explanations. However, despite a surge of attention for transposition there is no consensus regarding which type of variable is most important. In this book the focus on political variables is addressed. It is examined if such a focus is well founded, and whether and how different types of variables combine in order to produce the transposition outcome. To this end, a novel approach is taken by developing a theoretical framework that applies implementation theory to transposition. In this framework the three types of variables in the literature on transposition are combined in one coherent framework. The theoretical framework is applied mainly in a case study setting. The transposition of two packages of directives in the fields of telecommunications and energy in the Netherlands, Germany and Greece is studied in detail. The main conclusion is that political factors play an important role for the timeliness of transposition, but that a number of 'mediating' variables of institutional

    A computer based simulation method was developed to assess the relative effectiveness and availability of various attenuation compensation algorithms in single photon emission computed tomography (SPECT). The effect of the nonuniformity of attenuation coefficient distribution in the body, the errors in determining a body contour and the statistical noise on reconstruction accuracy and the computation time in using the algorithms were studied. The algorithms were classified into three groups: precorrection, post correction and iterative correction methods. Furthermore, a hybrid method was devised by combining several methods. This study will be useful for understanding the characteristics limitations and strengths of the algorithms and searching for a practical correction method for photon attenuation in SPECT. (orig.)

    2007-01-01

    Aim: the aim of this work is to study the influence of medium density on the CT or external source attenuation corrected images, by simulation on a phantom, with various positron emission tomographs. Material and method: a series of experiments on a cylindrical phantom filled with water marked with [18 F]-FDG, containing six vials filled per pair with mediums of different densities or solutions of KI, CaCl 2 and saccharose with various densities, was carried out under comparable conditions on three different tomographs. In only one of the vials of each pair, an identical radioactivity of [18 F]-FDG was added, three to five fold the surrounding activity. The reconstructions and attenuation corrections suggested by the manufacturers, were carried out under the usual conditions of each site. The activity of each structure was estimated by the methods of profiles and regions of interest, on the non attenuation corrected images (N.A.C.), the images corrected by CT (C.T.A.C.), and/or external source (G.P.A.C.). Results: with all three tomographs, the activities estimated on the N.A.C. images present an inverse correlation to the medium density (important absorption by dense material). On C.T.A.C. images, we observed with only two of the three tomographs, an overestimation of the activity in the 'radioactive' vials, depending on the medium mean Z number and density (over correction), and a artifactual 'activity' in the denser 'cold' vial (incorrect attenuation correction. The dense saccharose solutions, with non elevated Z number, do not affect the CT attenuation correction. (authors)

  10. Using machine-coded event data for the micro-level study of political violence

    Directory of Open Access Journals (Sweden)

    Jesse Hammond

    2014-07-01

    Full Text Available Machine-coded datasets likely represent the future of event data analysis. We assess the use of one of these datasets—Global Database of Events, Language and Tone (GDELT—for the micro-level study of political violence by comparing it to two hand-coded conflict event datasets. Our findings indicate that GDELT should be used with caution for geo-spatial analyses at the subnational level: its overall correlation with hand-coded data is mediocre, and at the local level major issues of geographic bias exist in how events are reported. Overall, our findings suggest that due to these issues, researchers studying local conflict processes may want to wait for a more reliable geocoding method before relying too heavily on this set of machine-coded data.

    Ji Zhilong; Ma Yuanwei; Wang Dezhong

    2014-01-01

    Background: In radioactive nuclides atmospheric diffusion models, the empirical dispersion coefficients were deduced under certain experiment conditions, whose difference with nuclear accident conditions is a source of deviation. A better estimation of the radioactive nuclide's actual dispersion process could be done by correcting dispersion coefficients with observation data, and Genetic Algorithm (GA) is an appropriate method for this correction procedure. Purpose: This study is to analyze the fitness functions' influence on the correction procedure and the forecast ability of diffusion model. Methods: GA, coupled with Lagrange dispersion model, was used in a numerical simulation to compare 4 fitness functions' impact on the correction result. Results: In the numerical simulation, the fitness function with observation deviation taken into consideration stands out when significant deviation exists in the observed data. After performing the correction procedure on the Kincaid experiment data, a significant boost was observed in the diffusion model's forecast ability. Conclusion: As the result shows, in order to improve dispersion models' forecast ability using GA, observation data should be given different weight in the fitness function corresponding to their error.

    1995-01-01

    This study presents different ballistic correction methods versus input count rate (from 3 to 50 kcounts/s) using four large Ge detectors of about 70 % relative efficiency. It turns out that the Tennelec TC245 linear amplifier in the BDC mode (Hinshaw method) is the best compromise for energy resolution throughout. All correction methods lead to narrow sum-peaks indistinguishable from single Γ lines. The full energy peak throughput is found representative of the pile-up inspection dead time of the corrector circuits. This work also presents a new and simple representation, plotting simultaneously energy resolution and throughput versus input count rate. (TEC). 12 refs., 11 figs

    Full Text Available Walter Benjamin’s observation that fascism turns politics into aesthetics is, by now, a well-worn idea. This article argues that Benjamin’s critique of politics can apply just as much to the modern democratic politics of the United States. Borrowing from Benjamin, Jürgen Habermas, and Carl Schmitt, this article suggests that modern political discourse in the United States does not follow the classical liberal ideal of rational discourse in the marketplace of ideas within the public sphere. Instead, contemporary politics has become spectacle where images and slogans replace thought and debate in a 24/7 news cycle and political infotainment programs. The result is that progressives and conservatives have their own political “ecospheres” which enable them to have their own perspective reinforced, and debate is replaced by straw man arguments and personal attacks.

    Full Text Available The paper considers a task of generating the requirements and creating a calibration target for automated microscopy systems (AMS of biomedical specimens to provide the invariance of algorithms and software to the hardware configuration. The required number of color fields of the calibration target and their color coordinates are mostly determined by the color correction method, for which coefficients of the equations are estimated during the calibration process. The paper analyses existing color calibration techniques for digital imaging systems using an optical microscope and shows that there is a lack of published results of comparative studies to demonstrate a particular useful color correction method for microscopic images. A comparative study of ten image color correction methods in RGB space using polynomials and combinations of color coordinate of different orders was carried out. The method of conditioned least squares to estimate the coefficients in the color correction equations using captured images of 217 color fields of the calibration target Kodak Q60-E3 was applied. The regularization parameter in this method was chosen experimentally. It was demonstrated that the best color correction quality characteristics are provided by the method that uses a combination of color coordinates of the 3rd order. The study of the influence of the number and the set of color fields included in calibration target on color correction quality for microscopic images was performed. Six train sets containing 30, 35, 40, 50, 60 and 80 color fields, and test set of 47 color fields not included in any of the train sets were formed. It was found out that the train set of 60 color fields minimizes the color correction error values for both operating modes of digital camera: using "default" color settings and with automatic white balance. At the same time it was established that the use of color fields from the widely used now Kodak Q60-E3 target does not

While MGIMO-University is celebrating its 70th anniversary the Department of Political Sciences turns 15. Despite the fact that political analyst is a relatively new profession in Russia, it acquired a legal standing only in the 1990s, the political science school at MGIMO-University is almost as old as the university itself. Unlike many other universities, focused on the training teachers of political science or campaign managers MGIMO-University has developed its own unique political science school of "full cycle", where students grow into political sciences from a zero level up to the highest qualifications as teachers and researchers, and campaign managers, consultants and practitioners. The uniqueness of the school of political science at MGIMO-University allows its institutional incarnation -the Department of Political Science - to offer prospective studentsa training in a wide range of popular specialties and specializations, while ensuring a deep theoretical and practical basis of the training. Studying at MGIMO-University traditionally includes enhanced linguistic component (at least two foreign languages. For students of international relations and political science learning foreign languages is particularly important.It allows not only to communicate, but also to produce expertise and knowledge in foreign languages.

    Full Text Available The development of new technologies, implicitely that of Internet contributed to the reconfiguration of the political communication field. In this respect, politicians report themselves to an electorate that is more detached from institutionalized politics and political ideologies, electorate that has the possibility to participate to debating alternative forms of the political, through some social movements and through online forums. Generally, new media created the possibility that journalists and media production agencies imagine more dynamic media formats from the point of view of interaction with citizens and visual strategies. Within the new context coming from the relation between politician, media and electorate, the Internet, through its functions, generates a special kind of „political communication management”.

    2011-01-01

    We propose a new approach to the study of the interquark potential in Lattice Gauge Theories. Instead of looking at the expectation value of Polyakov loop correlators we study the modifications induced in the chromoelectric flux by the presence of the Polyakov loops. In abelian LGTs, thanks to duality, this study can be performed in a very efficient way, allowing to reach high precision at a reasonable CPU cost. The major advantage of this strategy is that it allows us to eliminate the dominant effective string correction to the interquark potential (the Luescher term) thus giving an unique opportunity to test higher order corrections. Performing a set of simulations in the 3d spin Ising model and then translating the result in the 3d gauge Ising model using duality, we were thus able to precisely identify and measure both the quartic and the sextic effective string corrections to the interquark potential. While the quartic term perfectly agrees with the Nambu-Goto one the sextic term is definitely different. Our result seems to disagree with the recent proof of the universality of the sextic correction. We discuss a few possible explanations of this disagreement. (orig.)

  14. Attenuation correction for freely moving small animal brain PET studies based on a virtual scanner geometry

    2014-01-01

    Attenuation correction in positron emission tomography brain imaging of freely moving animals is a very challenging problem since the torso of the animal is often within the field of view and introduces a non negligible attenuating factor that can degrade the quantitative accuracy of the reconstructed images. In the context of unrestrained small animal imaging, estimation of the attenuation correction factors without the need for a transmission scan is highly desirable. An attractive approach that avoids the need for a transmission scan involves the generation of the hull of the animal’s head based on the reconstructed motion corrected emission images. However, this approach ignores the attenuation introduced by the animal’s torso. In this work, we propose a virtual scanner geometry which moves in synchrony with the animal’s head and discriminates between those events that traversed only the animal’s head (and therefore can be accurately compensated for attenuation) and those that might have also traversed the animal’s torso. For each recorded pose of the animal’s head a new virtual scanner geometry is defined and therefore a new system matrix must be calculated leading to a time-varying system matrix. This new approach was evaluated on phantom data acquired on the microPET Focus 220 scanner using a custom-made phantom and step-wise motion. Results showed that when the animal’s torso is within the FOV and not appropriately accounted for during attenuation correction it can lead to bias of up to 10% . Attenuation correction was more accurate when the virtual scanner was employed leading to improved quantitative estimates (bias < 2%), without the need to account for the attenuation introduced by the extraneous compartment. Although the proposed method requires increased computational resources, it can provide a reliable approach towards quantitatively accurate attenuation correction for freely moving animal studies.

    In Hungary one can mostly find references to the psychological processes of politics in the writings of publicists, public opinion pollsters, philosophers, social psychologists, and political analysts. It would be still important if not only legal scientists focusing on political institutions or sociologist-politologists concentrating on social structures could analyse the psychological aspects of political processes; but one could also do so through the application of the methods of political psychology. The authors review the history of political psychology, its position vis-à-vis other fields of science and the essential interfaces through which this field of science, which is still to be discovered in Hungary, connects to other social sciences. As far as its methodology comprising psycho-biographical analyses, questionnaire-based queries, cognitive mapping of interviews and statements are concerned, it is identical with the psychiatric tools of medical sciences. In the next part of this paper, the focus is shifted to the essence and contents of political psychology. Group dynamics properties, voters' attitudes, leaders' personalities and the behavioural patterns demonstrated by them in different political situations, authoritativeness, games, and charisma are all essential components of political psychology, which mostly analyses psychological-psychiatric processes and also involves medical sciences by relying on cognitive and behavioural sciences. This paper describes political psychology, which is basically part of social sciences, still, being an interdisciplinary science, has several ties to medical sciences through psychological and psychiatric aspects.

  17. Political liberalism and religious claims

    Science.gov (United States)

    2016-01-01

    This article gives an overview of 4 important lacunae in political liberalism and identifies, in a preliminary fashion, some trends in the literature that can come in for support in filling these blind spots, which prevent political liberalism from a correct assessment of the diverse nature of religious claims. Political liberalism operates with implicit assumptions about religious actors being either ‘liberal’ or ‘fundamentalist’ and ignores a third, in-between group, namely traditionalist religious actors and their claims. After having explained what makes traditionalist religious actors different from liberal and fundamentalist religious actors, the author develops 4 areas in which political liberalism should be pushed further theoretically in order to correctly theorize the challenge which traditional religious actors pose to liberal democracy. These 4 areas (blind spots) are: (1) the context of translation; (2) the politics of exemptions; (3) the multivocality of theology; and (4) the transnational nature of norm-contestation.

    2017-01-01

    Epidemiological studies often utilize stratified data in which rare outcomes or exposures are artificially enriched. This design can increase precision in association tests but distorts predictions when applying classifiers on nonstratified data. Several methods correct for this so-called sample selection bias, but their performance remains unclear especially for machine learning classifiers. With an emphasis on two-phase case-control studies, we aim to assess which corrections to perform in which setting and to obtain methods suitable for machine learning techniques, especially the random forest. We propose two new resampling-based methods to resemble the original data and covariance structure: stochastic inverse-probability oversampling and parametric inverse-probability bagging. We compare all techniques for the random forest and other classifiers, both theoretically and on simulated and real data. Empirical results show that the random forest profits from only the parametric inverse-probability bagging proposed by us. For other classifiers, correction is mostly advantageous, and methods perform uniformly. We discuss consequences of inappropriate distribution assumptions and reason for different behaviors between the random forest and other classifiers. In conclusion, we provide guidance for choosing correction methods when training classifiers on biased samples. For random forests, our method outperforms state-of-the-art procedures if distribution assumptions are roughly fulfilled. We provide our implementation in the R package sambia. PMID:29312464

    Full Text Available The present study aims to examine corrective feedback and learner uptake in classroom interactions. Inspired by Lyster and Ranta’s corrective feedback framework (1997, this study intends to describe and analyze the patterns of corrective feedback utilized by Iranian teachers, and learners' uptake and the repair of those errors. To this aim, 400 minutes of classroom interaction from three elementary EFL classes which comprised 29 EFL learners were audiotaped and transcribed. The learners were within age range of 16-29 and were native speakers of Turkish language. The teachers were within 26-31 age range and had 3-4 years experience of teaching and hold MA degree in TOEFL. Analysis of data constituted the frequency of six different feedback types used by three teachers, in addition distribution of learners' uptake following each feedback type. The findings indicated that among six corrective feedback types, recast was the most frequent feedback utilized by teachers although it did not lead to high amount of learner uptake. Metalinguistic feedback, elicitation and clarification request led to higher level of uptake. It was also found that explicit feedback was more effective than implicit feedback in promoting learner uptake.

    Full Text Available The Normality of EU Sport Policy Studies: Disciplinary Locus in Political Science, Sport Science or Elsewhere? Mainstream European integration research has shown that research on the EU tends to follow the conjunctures of European integration itself. This realisation has led to some debate on which branch of political science – international relations or government – or indeed other academic disciplines is/are the most appropriate locus for such research. The paper takes these debates one step further by looking at the occurrence of ‘EU & sport’ studies within the wider field of EU studies. The main material used comes from the ECLAS database. Findings lead to a discussion of whether ‘EU & sport’ studies should rather be for EU specialists or for sport specialists and a plea for disciplinary normalisation whereby sport science would need to get more directly involved (without necessarily overwriting political science. Some ideas are added regarding the need for a mapping of Central & Eastern European scholarship. Normalita politických studií EU v oblasti sportu: místo v oborech politologie, sportovních vědách či jinde?

  7. Do Political Attitudes Affect Consumer Choice? Evidence from a Large-Scale Field Study with Genetically Modified Bread in Switzerland

    Directory of Open Access Journals (Sweden)

    Philipp Aerni

    2011-09-01

    Full Text Available Independent of the left-right model of ideological structure, genetically modified organisms (GMOs in food and agriculture are resented across the political spectrum in Switzerland. In the absence of any real experience with genetically modified (GM food but faced with continuous exposure to warning messages in the media, conditioned feelings related to such a politically sensitive product may have a significant influence on revealed consumer choice. In our large-scale field study, we examined this assumption by selling three types of bread labeled as ‘made with organic corn’, ‘made with genetically modified corn’ and ‘made with conventional corn’ respectively in five locations across Switzerland using different price scenarios and selling groups. Customers who decided to buy bread also received an envelope containing a questionnaire about their prior political attitude expressed through their voting decision in a national referendum on a five-year ban on GMOs in 2005. The results demonstrate that consumer purchase decisions are determined by contextual factors not captured by general political attitudes. Surprisingly, the mere presence of GM food did have a positive impact on overall sales. The assumption that consumers would feel turned off by the mere presence of GM food for political reasons can therefore be safely discarded.

    Political campaigns are orchestrated attempts by political organizations to garner public support through persuasive communication in order to influence public policy in their favor. This broad definition encapsulates all forms of campaigns from those of neighborhood organizations seeking to influence local politicians to the campaigns of political parties and candidates who seek election to office in order to shape policy themselves. In pluralist democracies, campaigns are crucial for repres...

    We engage a discussion of political CSR in SMEs in an African context. Based on critical observations on Western MNC CSR action in emerging economies that holds counterproductive implications for social development, political economists have argued that business profit far more than society...... development in local African communities. Our findings extend political CSR research by directing attention to how the corporate influence in developing economies does not only emerge from MNCs but is also established and retained by SMEs CSR work....

    Mobile computing technology presents various possibilities and challenges for psychological assessment. Within forensic and correctional psychology, assessment of justice-involved persons facilitated by such technology has not been empirically examined. Accordingly, this randomized controlled experiment involved administering questionnaires about risk-needs, treatment readiness, and computerized technology opinions to a large (N = 212) and diverse sample of individuals under custodial correctional supervision using either a tablet computer or traditional paper-and-pencil materials. Results revealed that participants in the paper-and-pencil condition completed the packet of questionnaires faster but omitted items more frequently. Older participants and those with lower levels of education tended to take longer to complete the tablet-administrated measures. The tablet format was rated as more usable irrespective of demographic and personal characteristics, and most participants across the 2 conditions indicated that they would prefer to use computerized technology to complete psychological testing. Administration format did not have a clear effect on attitudes toward correctional rehabilitation services. Noteworthy for researchers is the substantial time saved and absence of practical problems with the tablet condition. Implications for practitioners include the general usability of the devices, their appeal to incarcerated persons, and the potential for tablets to facilitate clinical and administrative tasks with corrections clients. Considering the novel nature of this study, its promising results, and its limitations, future research in this area is warranted. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

    The biocompatibility and functionality of a new scoliosis correction device, based on the properties of the shape-memory metal nickel-titanium alloy, were studied. With this device, the shape recovery forces of a shape-memory metal rod are used to achieve a gradual three-dimensional scoliosis correction. In the experimental study the action of the new device was inverted: the device was used to induce a scoliotic curve instead of correcting one. Surgical procedures were performed in six pigs. An originally curved squared rod, in the cold condition, was straightened and fixed to the spine with pedicle screws. Peroperatively, the memory effect of the rod was activated by heating the rod to 50 degrees C by a low-voltage, high-frequency current. After 3 and after 6 months the animals were sacrificed. The first radiographs, obtained immediately after surgery, showed in all animals an induced curve of about 40 degrees Cobb angle - the original curve of the rod. This curve remained constant during the follow-up. The postoperative serum nickel measurements were around the detection limit, and were not significantly higher compared to the preoperative nickel concentration. Macroscopic inspection after 3 and 6 months showed that the device was almost overgrown with newly formed bone. Corrosion and fretting processes were not observed. Histologic examination of the sections of the surrounding tissues and sections of the lung, liver, spleen and kidney showed no evidence of a foreign body response. In view of the initiation of the scoliotic deformation, it is expected that the shape-memory metal based scoliosis correction device also has the capacity to correct a scoliotic curve. Moreover, it is expected that the new device will show good biocompatibility in clinical application. Extensive fatigue testing of the whole system should be performed before clinical trials are initiated.

  13. Final corrective action study for the former CCC/USDA facility in Ramona, Kansas.

    Past operations at a grain storage facility formerly leased and operated by the Commodity Credit Corporation of the U.S. Department of Agriculture (CCC/USDA) in Ramona, Kansas, resulted in low concentrations of carbon tetrachloride in groundwater that slightly exceed the regulatory standard in only one location. As requested by the Kansas Department of Health and Environment, the CCC/USDA has prepared a Corrective Action Study (CAS) for the facility. The CAS examines corrective actions to address groundwater impacted by the former CCC/USDA facility but not releases caused by other potential groundwater contamination sources in Ramona. Four remedial alternatives were considered in the CAS. The recommended remedial alternative in the CAS consists of Environmental Use Control to prevent the inadvertent use of groundwater as a water supply source, coupled with groundwater monitoring to verify the continued natural improvement in groundwater quality. The Commodity Credit Corporation of the U.S. Department of Agriculture (CCC/USDA) has directed Argonne National Laboratory to prepare a Corrective Action Study (CAS), consistent with guidance from the Kansas Department of Health and Environment (KDHE 2001a), for the CCC/USDA grain storage facility formerly located in Ramona, Kansas. This effort is pursuant to a KDHE (2007a) request. Although carbon tetrachloride levels at the Ramona site are low, they remain above the Kansas Tier 2 risk-based screening level (RBSL) and the U.S. Environmental Protection Agency (EPA) maximum contaminant level (MCL) of 5 {micro}g/L (Kansas 2003, 2004). In its request for the CAS, the KDHE (2007a) stated that, because of these levels, risk is associated with potential future exposure to contaminated groundwater. The KDHE therefore determined that additional measures are warranted to limit future use of the property and/or exposure to contaminated media as part of site closure. The KDHE further requested comparison of at least two corrective

    Full Text Available The article discusses the contribution of Croatian political science to the development of democracy in Croatia. The focus of the analysis is the concept of culture which author talks about in five steps. In the first step it is understood in the modern key, in the second step as different for nature and in the third as different from society. In the fourth step author differentiates political culture from political economy and political institutions, but in the fifth part there is an attempt to show culture as a fundamental part of politics, policy and polity. On the basis of these insights author shows that the matrix of Croatian political science is more and more devoted to scientific investigation of politics as culture as both study of political culture and as a source of development as politics as culture.

    To gain and retain political power, politicians utilise the mass media to persuade the polity to support them, especially during elections. The Barisan Nasional (BN) coalition has successfully manipulated the mass media in Malaysia to maintain power for the past 57 years, making it one of the longest serving government in the world. The emergence of new media, however, has challenged this status quo. The purpose of this thesis was to investigate how new media has influenced the political proc...

    Purpose: Scatter correction is a major challenge in x-ray imaging using large area detectors. Recently, the authors proposed a promising scatter correction method for x-ray computed tomography (CT) using primary modulation. Proof of concept was previously illustrated by Monte Carlo simulations and physical experiments on a small phantom with a simple geometry. In this work, the authors provide a quantitative evaluation of the primary modulation technique and demonstrate its performance in applications where scatter correction is more challenging. Methods: The authors first analyze the potential errors of the estimated scatter in the primary modulation method. On two tabletop CT systems, the method is investigated using three phantoms: A Catphan(c)600 phantom, an anthropomorphic chest phantom, and the Catphan(c)600 phantom with two annuli. Two different primary modulators are also designed to show the impact of the modulator parameters on the scatter correction efficiency. The first is an aluminum modulator with a weak modulation and a low modulation frequency, and the second is a copper modulator with a strong modulation and a high modulation frequency. Results: On the Catphan(c)600 phantom in the first study, the method reduces the error of the CT number in the selected regions of interest (ROIs) from 371.4 to 21.9 Hounsfield units (HU); the contrast to noise ratio also increases from 10.9 to 19.2. On the anthropomorphic chest phantom in the second study, which represents a more difficult case due to the high scatter signals and object heterogeneity, the method reduces the error of the CT number from 327 to 19 HU in the selected ROIs and from 31.4% to 5.7% on the overall average. The third study is to investigate the impact of object size on the efficiency of our method. The scatter-to-primary ratio estimation error on the Catphan(c)600 phantom without any annulus (20 cm in diameter) is at the level of 0.04, it rises to 0.07 and 0.1 on the phantom with an

    This study's objective was to understand how art therapy and mindfulness meditation could be integrated together in the context of different cultures and political violence and in work with asylum seekers suffering from trauma. We conducted a qualitative phenomenological study based on the social construction paradigm. Twelve participants took part in 4 intensive full-day art therapy and mindfulness workshops. The study's setting was an art therapy and mindfulness studio ( Inhabited Studio ) in Hong Kong where participants engaged in art making and in mindfulness-meditation practice. Different aspects of the Inhabited Studio appealed to participants based on each individual's worldview, culture, religion, and coping style. Responses to the Inhabited Studio were organized into 7 thematic clusters. Five themes were categorized into 2 broad categories composed of personal elements (memory, identity) and mediating aspects (emotional/self-regulation, communication, and imagination). The final 2, resilience and worldview, spanned both areas. Participants found the Inhabited Studio culturally compatible and some of the skills they learned helpful in times of stress. This points to how this combination can contribute to building resilience. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

    This double-blind study examined the effect of electromyographical (EMG) artifacts, which contaminate electroencephalographical (EEG) signals, by comparing artifact-corrected (AC) and non-artifact-corrected (NAC) neurofeedback (NF) training procedures. 14 unmedicated college students were randomly assigned to two groups: AC (n = 7) or NAC (n = 7). Both groups received 12 sessions of NF and were trained using identical NF treatment protocols to reduce their theta/beta power ratios (TBPR). Outcomes on a continuous performance test revealed that the AC group had statistically significant increases across measures of auditory and visual attention. The NAC group showed smaller gains that only reached statistical significance on measures of visual attention. Only the AC group reduced their TBPR, the NAC group did not. AC NF appears to play an important role during training that leads to improvements in both auditory and visual attention. Additional research is required to confirm the results of this study.

    International Nuclear Information System (INIS)

    Kim, Y.P.

    1982-01-01

    The sensational Three Mile Island Nuclear Power Plant Accident of 1979 raised many policy problems. Since the TMI accident, many authorities in the nation, including the President's Commission on TMI, Congress, GAO, as well as NRC, have researched lessons and recommended various corrective measures for the improvement of nuclear regulatory policy. As an effort to translate the recommendations into effective actions, the NRC developed the TMI Action Plan. How sound are these corrective actions. The NRC approach to the TMI Action Plan is justifiable to the extent that decisions were reached by procedures to reduce the effects of judgmental bias. Major findings from the NRC's effort to justify the corrective actions include: (A) The deficiencies and errors in the operations at the Three Mile Island Plant were not defined through a process of comprehensive analysis. (B) Instead, problems were identified pragmatically and segmentally, through empirical investigations. These problems tended to take one of two forms - determinate problems subject to regulatory correction on the basis of available causal knowledge, and indeterminate problems solved by interim rules plus continuing study. The information to justify the solution was adjusted to the problem characteristics. (C) Finally, uncertainty in the determinate problems was resolved by seeking more causal information, while efforts to resolve indeterminate problems relied upon collective judgment and a consensus rule governing decisions about interim resolutions

    Full Text Available Youth participation through political talk appears to be shifting to the online public sphere in many parts of the world. Many attribute this shift to online social networks such as Facebook. Emerging research seem to suggest that this may be a cure for the problem of political apathy among the youth. This study explores such a possibility in Jamaica. In all, 752 youth ages 15 to 24 were surveyed to ascertain whether Facebook encourages political talk among this age cohort, and what if any are the primary factors that discourage this practice. The findings suggest that (a Facebook is an extension of offline political talk among the civically engaged and politically charged youth of Jamaica; (b Facebook does not substantively encourage political talk among the politically apathetic Jamaican youth; and (c fear of political victimization is the primary factor that discourages many Jamaican youth to engage in political talk on Facebook.

    Political psychology is a dynamic field of research that offers a unique blend of approaches and methods in the social and cognitive sciences. Political psychologists explore the interactions between macrolevel political structures and microlevel factors such as decision-making processes, motivations, and perceptions. In this article, we provide a broad overview of the field, beginning with a brief history of political psychology research and a summary of the primary methodological approaches in the field. We then give a more detailed account of research on ideology and social justice, two topics experiencing a resurgence of interest in current political psychology. Finally, we cover research on political persuasion and voting behavior. By summarizing these major areas of political psychology research, we hope to highlight the wide variety of theoretical and methodological approaches of cognitive scientists working at the intersection of psychology and political science.

  8. Quantitative studies with the gamma-camera: correction for spatial and energy distortion

    International Nuclear Information System (INIS)

    Soussaline, F.; Todd-Pokropek, A.E.; Raynaud, C.

    1977-01-01

    The gamma camera sensitivity distribution is an important source of error in quantitative studies. In addition, spatial distortion produces apparent variations in count density which degrades quantitative studies. The flood field image takes into account both effects and is influenced by the pile-up of the tail distribution. It is essential to measure separately each of these parameters. These were investigated using a point source displaced by a special scanning table with two X, Y stepping motors of 10 micron precision. The spatial distribution of the sensitivity, spatial distortion and photopeak in the field of view were measured and compared for different setting-up of the camera and PM gains. For well-tuned cameras, the sensitivity is fairly constant, while the variations appearing in the flood field image are primarily due to spatial distortion, the former more dependent than the latter on the energy window setting. This indicates why conventional flood field uniformity correction must not be applied. A correction technique to improve the results in quantitative studies has been tested using a continuously matched energy window at every point within the field. A method for correcting spatial distortion is also proposed, where, after an adequately sampled measurement of this error, a transformation can be applied to calculate the true position of events. The knowledge of the magnitude of these parameters is essential in the routine use and design of detector systems

  9. Political dynamics promoting the incremental regulation of secondhand smoke: a case study of New South Wales, Australia

    2006-07-01

    Full Text Available Abstract Background The history of governmental responses to the accumulation of scientific evidence about the harms of secondhand smoke (SHS presents an intriguing case study of incremental public health policy development. Australia has long been considered a world-leader in progressive tobacco control policies, but in the last decade has fallen behind other jurisdictions in introducing SHS legislation that protects all workers. Bars, clubs and pubs remain the only public indoor spaces where smoking is legally permitted, despite SHS exposure in the hospitality industry being higher and affecting more people than in any other setting after domestic exposure. This paper examines the political dynamics that have shaped this incremental approach to SHS. Methods In-depth interviews with 21 key stakeholders in the state of New South Wales (NSW, including politicians, their advisors, health officials and tobacco control advocates, were conducted and subjected to thematic content analysis. Interviewees' comments provided insights into the dynamics surrounding the debates and outcomes of SHS legislative attempts and the current political environment, and about how to progress SHS legislation. Results SHS restrictions have been delayed by several broad factors: the influence of industry groups successfully opposing regulation; issue wear-out; and political perceptions that there is not a salient constituency demanding that smoking be banned in bars and clubs. Interviewees also provided suggestions of strategies that advocates might utilise to best overcome the current political inertia of incremental compromises and achieve timely comprehensive smoking bans. Conclusion Advocates concerned to shorten the duration of incremental endgames must continue to insist that governments address SHS fundamentally as a health issue rather than making political concessions to industry groups, and should broaden and amplify community voices calling on governments to

    Highlights: •Uncertainty over overlapping energy and climate policies affects investment choices. •An integrated real options and portfolio optimisation model is used in a case study. •Interacting carbon pricing and renewable supports can create private and social hedge. •Political uncertainty may justify overlapping carbon pricing and renewable supports. -- Abstract: The translation of a greenhouse gas (GHG) emissions reduction policy objective to the required investment in low emissions technologies may be hindered by political contest over the policy instruments employed to achieve it. Political contest may also result in enactment of overlapping policy instruments which, from a ‘policy purist’ perspective, may not appear well calibrated to a shared GHG emissions reduction objective. This paper reports insights gained from an integrated real options and portfolio optimisation model of electricity generation investment behaviour under political uncertainty over the futures of interacting carbon pricing and renewable portfolio standard (RPS) instruments. We compare modelling results and actual outcomes in Australia, where an emission reduction target has had bipartisan support but the means to achieve it has not, to test the assertion that overlapping policy instruments must always increase the social costs of GHG abatement. Results suggest that overlapping a politically contested carbon pricing policy with an RPS may result in a lower risk, renewable energy (RE) investment environment, as the overlap allows investors to hedge their portfolio against political uncertainty through RE additions. Consequently, GHG abatement objectives may be achieved at lower cost than would be the case without the policy interaction. The policies overlap can provide a ‘safety valve’ or ‘hedge’ to both private investors and policymakers when deep uncertainties over the future of energy and climate policies influence investment strategies.

    Quantification of breast density based on three-dimensional breast MRI may provide useful information for the early detection of breast cancer. However, the field inhomogeneity can severely challenge the computerized image segmentation process. In this work, the effect of the bias field in breast density quantification has been investigated with a postmortem study. T1-weighted images of 20 pairs of postmortem breasts were acquired on a 1.5 T breast MRI scanner. Two computer-assisted algorithms were used to quantify the volumetric breast density. First, standard fuzzy c-means (FCM) clustering was used on raw images with the bias field present. Then, the coherent local intensity clustering (CLIC) method estimated and corrected the bias field during the iterative tissue segmentation process. Finally, FCM clustering was performed on the bias-field-corrected images produced by CLIC method. The left-right correlation for breasts in the same pair was studied for both segmentation algorithms to evaluate the precision of the tissue classification. Finally, the breast densities measured with the three methods were compared to the gold standard tissue compositions obtained from chemical analysis. The linear correlation coefficient, Pearson's r, was used to evaluate the two image segmentation algorithms and the effect of bias field. The CLIC method successfully corrected the intensity inhomogeneity induced by the bias field. In left-right comparisons, the CLIC method significantly improved the slope and the correlation coefficient of the linear fitting for the glandular volume estimation. The left-right breast density correlation was also increased from 0.93 to 0.98. When compared with the percent fibroglandular volume (%FGV) from chemical analysis, results after bias field correction from both the CLIC the FCM algorithms showed improved linear correlation. As a result, the Pearson's r increased from 0.86 to 0.92 with the bias field correction. The investigated CLIC method

    The Phase 1 LHC Interaction Region (IR) upgrade aims at increasing the machine luminosity essentially by reducing the beam size at the Interaction Point (IP). This requires a total redesign of the full IR. A large set of options has been proposed with conceptually different designs. This paper reports on a general approach for the compensation of the multipolar errors of the IR magnets in the design phase. The goal is to use the same correction approach for the different designs. The correction algorithm is based on the minimization of the differences between the IR transfer map with errors and the design IR transfer map. Its performance is tested using the dynamic aperture as figure of merit. The relation between map coefficients and resonance terms is also given as a way to target particular resonances by selecting the right map coefficients. The dynamic aperture is studied versus magnet aperture using recently established relations between magnetic errors and magnet aperture.

    Abstract. Protein-protein interactions in cells are often studied using fluorescence resonance energy transfer (FRET) phenomenon by fluorescence lifetime imaging microscopy (FLIM). Here, we demonstrate approaches to the quantitative analysis of FRET in cell population in a case complicated by a highly heterogeneous donor expression, multiexponential donor lifetime, large contribution of cell autofluorescence, and significant presence of unquenched donor molecules that do not interact with the acceptor due to low affinity of donor-acceptor binding. We applied a multifrequency phasor plot to visualize FRET FLIM data, developed a method for lifetime background correction, and performed a detailed time-resolved analysis using a biexponential model. These approaches were applied to study the interaction between the Toll Interleukin-1 receptor (TIR) domain of Toll-like receptor 4 (TLR4) and the decoy peptide 4BB. TLR4 was fused to Cerulean fluorescent protein (Cer) and 4BB peptide was labeled with Bodipy TMRX (BTX). Phasor displays for multifrequency FLIM data are presented. The analytical procedure for lifetime background correction is described and the effect of correction on FLIM data is demonstrated. The absolute FRET efficiency was determined based on the phasor plot display and multifrequency FLIM data analysis. The binding affinity between TLR4-Cer (donor) and decoy peptide 4BB-BTX (acceptor) was estimated in a heterogeneous HeLa cell population. PMID:24770662

    Scattering is quite important for image activity quantification. In order to study the scattering factors and the efficacy of 3 multiple window energy scatter correction methods during 131 I thyroid studies with a pinhole collimator (5 mm hole) a Monte Carlo simulation (MC) was developed. The GAMOS MC code was used to model the gamma camera and the thyroid source geometry. First, to validate the MC gamma camera pinhole-source model, sensibility in air and water of the simulated and measured thyroid phantom geometries were compared. Next, simulations to investigate scattering and the result of triple energy (TEW), Double energy (DW) and Reduced double (RDW) energy windows correction methods were performed for different thyroid sizes and depth thicknesses. The relative discrepancies to MC real event were evaluated. Results: The accuracy of the GAMOS MC model was verified and validated. The image’s scattering contribution was significant, between 27-40 %. The discrepancies between 3 multiple window energy correction method results were significant (between 9-86 %). The Reduce Double Window methods (15%) provide discrepancies of 9-16 %. Conclusions: For the simulated thyroid geometry with pinhole, the RDW (15 %) was the most effective. (author)

  1. Supersymmetric QCD corrections and phenomenological studies in relation to coannihilation of dark matter

    In this thesis, we assume a minimal supersymmetric extension of the Standard Model (MSSM) with conserved R-parity such that the lightest neutralino is the cold dark matter candidate. A stringent constraint on the MSSM parameter space can be set by the comparison of the predicted neutralino relic density with the experimentally determined value. In order to match the high experimental precision, uncertainties within the theoretical calculation have to be reduced. One of the main uncertainties arises from the cross section of annihilation and coannihilation processes of the dark matter particle. In a phenomenological study we investigate the interplay of neutralino-neutralino annihilation, neutralino-stop coannihilation and stop-stop annihilation. We demonstrate that neutralino-stop coannihilation contributes significantly to the neutralino relic density and is furthermore very well motivated due to the recent discovery of a 125 GeV Higgs boson. Due to this ample motivation we have calculated the full O({alpha}{sub s}) supersymmetric QCD corrections to neutralino-squark coannihilation. We show in detail our DR/on-shell renormalization scheme for the treatment of ultraviolet divergences, and describe the phase space slicing method which is used to handle soft and collinear infrared divergences. Further, we comment on the treatment of occurring intermediate onshell states. The whole calculation is provided within the numerical tool DM rate at NLO that serves as an extension to existing relic density calculators, which consider only an effective tree-level calculation. Based on three example scenarios we study the impact of the NLO corrections on the total (co)annihilation cross section, and observe corrections of up to 30 %. This leads to a correction of 5 - 9 % on the relic density, which is larger than the current experimental uncertainty and is, thus, important to be taken into account.

    Because of confounding from the urban/rural and socioeconomic organizations of territories and resulting correlation between residential and nonresidential exposures, classically estimated residential neighborhood-outcome associations capture nonresidential environment effects, overestimating residential intervention effects. Our study diagnosed and corrected this "residential" effect fallacy bias applicable to a large fraction of neighborhood and health studies. Our empirical application investigated the effect that hypothetical interventions raising the residential number of services would have on the probability that a trip is walked. Using global positioning systems tracking and mobility surveys over 7 days (227 participants and 7440 trips), we employed a multilevel linear probability model to estimate the trip-level association between residential number of services and walking to derive a naïve intervention effect estimate and a corrected model accounting for numbers of services at the residence, trip origin, and trip destination to determine a corrected intervention effect estimate (true effect conditional on assumptions). There was a strong correlation in service densities between the residential neighborhood and nonresidential places. From the naïve model, hypothetical interventions raising the residential number of services to 200, 500, and 1000 were associated with an increase by 0.020, 0.055, and 0.109 of the probability of walking in the intervention groups. Corrected estimates were of 0.007, 0.019, and 0.039. Thus, naïve estimates were overestimated by multiplicative factors of 3.0, 2.9, and 2.8. Commonly estimated residential intervention-outcome associations substantially overestimate true effects. Our somewhat paradoxical conclusion is that to estimate residential effects, investigators critically need information on nonresidential places visited.

    To evaluate and correct the impact of non-response in the prevalence of underweight, overweight and obesity in children aged 6 to 15 years old using silhouette scales. Cross-sectional study carried out in 2013 among 8,145 Galician schoolchildren aged 6-15 years old. The students who agreed to participate were weighed and measured and, based on body mass index, the prevalence of underweight, overweight and obesity was estimated. Teachers rated all students using silhouette scales. The valuations were used to estimate the prevalence corrected by non-response. Using the Bayes theorem, participation rates were estimated according to weight status. The participation rate was 92.3% in the 6 -to 11-year-old group, and 90% in the 12- to 15-year old age group. In both groups, the prevalence of underweight and overweight were similar between participants and non-participants. However, obesity was higher among non-participants, especially at 12 to 15 years of age (6.3% vs. 12.2% ; p < 0.05). The prevalence did not change when corrected by the teacher's valuation. The participation rate of obese students was lower than the overall rate (82% vs. 90% at 12 to 15 years old; p < 0.05). The presence of participation bias, which was greater at 12-15 years old, was confirmed. However, the impact of the bias on prevalence was negligible due to the high participation rate. In obesity studies with objective measures, it is essential to quantify non-participation, as well as to assess its impact and correct it. Copyright © 2017 SESPAS.

    Full Text Available This paper intends to study some of the main problems presented, on different scales, by current politics, considering the spatial implications as well as various parameters offered lately by the geographical science. The proposal is supported by the theoretical bases developed from Emmanuel Wallerstein and Peter Taylor's statement about a world system structured as a world economy, based on the capitalist mode of production. Conversely, it attempts to provide a theoretical explanation for the dynamics experienced by the territories upon thee basis of such world system's mechanics. According to these assumptions, an analysis is proposed of some of the main phenomena resulting from the previous analysis and its spatial implications, such as the current power relations in the system, the subsistence of traditional power factors (Nation-states, ethnically based cultural configurations and the appearance of new ones (the forming of transnational blocs and associations, new social movements, new forms of local participation, the importance of hegemonic and counter-hegemonic discourses in the construction of symbolic representations and of the mass media in such processes or the new cultural identity and hybridization chart from population mobility.

  5. The (limited) political influence of ecological economics. A case study on Dutch environmental policies

    Although the ecological economics (EE) discourse attempts to influence environmental policy, empirical studies have concluded that its success in this endeavour has been limited thus far. In the Netherlands, however, two EE-related policy concepts, Environmental Utilisation Space and Ecological Footprint, were strongly present in environmental policy during certain periods in time, but subsequently disappeared from the environmental agenda. The central question of this article is how these ups and downs of the EE concepts can be understood: which factors determine their rise on and fall from the policy agenda over time? To answer this question, this article offers a conceptual model informed by the approaches in political science on framing, agenda-setting and knowledge utilisation. We conclude that the interplay of concept-specific characteristics, the formation of coalitions around the concept and contextual variables explain the rise and fall of the aforementioned concepts. A match between the dominant policy frame and the core elements of the concept provides the opportunity for the two concepts to be pushed on the agenda. We observe the alternation of 'constraining' frames, which allows for EE concepts to survive, and 'reconciling' frames, which block agenda entrance for EE concepts. Furthermore, the alternation of these frames seems to correlate with economic and public environmental attention cycles in the Netherlands. (author)

    In this study, the quantitative accuracy of different attenuation correction strategies presently available for the High Resolution Research Tomograph (HRRT) was investigated. These attenuation correction methods differ in reconstruction and processing (segmentation) algorithms used for generating a μ-image from measured 2D transmission scans, an intermediate step in the generation of 3D attenuation correction factors. Available methods are maximum-a-posteriori reconstruction (MAP-TR), unweighted OSEM (UW-OSEM) and NEC-TR, which transforms sinogram values back to their noise equivalent counts (NEC) to restore Poisson distribution. All methods can be applied with or without μ-image segmentation. However, for MAP-TR a μ-histogram is a prior during reconstruction. All possible strategies were evaluated using phantoms of various sizes, simulating preclinical and clinical situations. Furthermore, effects of emission contamination of the transmission scan on the accuracy of various attenuation correction strategies were studied. Finally, the accuracy of various attenuation corrections strategies and its relative impact on the reconstructed activity concentration (AC) were evaluated using small animal and human brain studies. For small structures, MAP-TR with human brain priors showed smaller differences in μ-values for transmission scans with and without emission contamination (<8%) than the other methods (<26%). In addition, it showed best agreement with true AC (deviation <4.5%). A specific prior designed to take into account the presence of small animal fixation devices only very slightly improved AC precision to 4.3%. All methods scaled μ-values of a large homogeneous phantom to within 4% of the water peak, but MAP-TR provided most accurate AC after reconstruction. However, for clinical data MAP-TR using the default prior settings overestimated the thickness of the skull, resulting in overestimations of μ-values in regions near the skull and thus in incorrect

    This study was conducted to assess political mapping in relation to road traffic injuries (RTIs) management and prevention to present a practical model for RTIs. A phenomenological qualitative study was developed to identify stakeholders on RTI in Iran in 2008. The designed questions were discussed by systematic discussion with the relevant specialists. After receiving written consent from the main responsible stakeholders, the questionnaire was filled in by trained experts. Themes were determined and content was analysed in each part. Main responsible stakeholders. By comparing other countries' political mappings which were found in the library and by Internet searching, political mapping of RTI in Iran was suggested. Subjects were 26 experts from governmental and non-governmental organizations. The main proposed leading agencies were traffic police and presidency (13% each). Findings showed that only 31% of our political mapping was formed according to the World Health Organization (WHO). In 94% of cases, the involved organizations had unspecified roles; the reason was poor monitoring for RTI in 39% of organizations. Lack of adequate authority and suitable legislation, appropriate laws and tasks definition were 94% and 18%, respectively. The most essential policy to overcome problems was defined as appropriate legislation (21%), and the most frequent type of support needed was mentioned as adequate budgeting (25%). Traffic police can play the leading agency role by government support, with strong leadership, appropriate legislation, defined tasks and adequate budget.

    In clinical myocardial single photon emission computed tomography (SPECT), attenuation artefacts may cause a loss of specificity in the identification of diseased vessels that can be corrected by means of gated SPECT (GSPECT) acquisition or CT attenuation correction (AC). The purpose of this multicentre study was to assess the impact of GSPECT and AC on the diagnostic performance of myocardial scintigraphy, according to patient's sex, body mass index (BMI) and site of coronary artery disease (CAD). We studied a group of 104 patients who underwent coronary angiography within 1 month before or after the SPECT study. Patients with a BMI > 27 were considered ''overweight''. Attenuation-corrected and standard GSPECT early images were randomly interpreted by three readers blinded to the clinical data. In the whole group, GSPECT and AC showed a diagnostic accuracy of 86.5% (sensitivity 82%, specificity 93%) and 77% (sensitivity 75.4%, specificity 81.4%), respectively (p < 0.05). In women, when anterior ischaemia was matched with CAD, AC failed to show any increase in specificity (AC 63.6% vs GSPECT 63.6%) with evident loss of sensitivity (AC 72.7% vs GSPECT 90.9%). AC significantly improved SPECT specificity in the identification of right CAD in overweight men (AC 100% vs GSPECT 66.7%, p <0.05). AC improved specificity in the evaluation of right CAD in overweight men. In the other evaluable subgroups specificity was not significantly affected while sensitivity was frequently reduced.

  11. An Empirical Study of Atmospheric Correction Procedures for Regional Infrasound Amplitudes with Ground Truth.

    Howard, J. E.

    2014-12-01

    This study focusses on improving methods of accounting for atmospheric effects on infrasound amplitudes observed on arrays at regional distances in the southwestern United States. Recordings at ranges of 150 to nearly 300 km from a repeating ground truth source of small HE explosions are used. The explosions range in actual weight from approximately 2000-4000 lbs. and are detonated year-round which provides signals for a wide range of atmospheric conditions. Three methods of correcting the observed amplitudes for atmospheric effects are investigated with the data set. The first corrects amplitudes for upper stratospheric wind as developed by Mutschlecner and Whitaker (1999) and uses the average wind speed between 45-55 km altitudes in the direction of propagation to derive an empirical correction formula. This approach was developed using large chemical and nuclear explosions and is tested with the smaller explosions for which shorter wavelengths cause the energy to be scattered by the smaller scale structure of the atmosphere. The second approach isa semi-empirical method using ray tracing to determine wind speed at ray turning heights where the wind estimates replace the wind values in the existing formula. Finally, parabolic equation (PE) modeling is used to predict the amplitudes at the arrays at 1 Hz. The PE amplitudes are compared to the observed amplitudes with a narrow band filter centered at 1 Hz. An analysis is performed of the conditions under which the empirical and semi-empirical methods fail and full wave methods must be used.

    2018-05-01

    This work assesses the suitability of a first simple attempt for process-conditioned bias correction in the context of seasonal forecasting. To do this, we focus on the northwestern part of Peru and bias correct 1- and 4-month lead seasonal predictions of boreal winter (DJF) precipitation from the ECMWF System4 forecasting system for the period 1981-2010. In order to include information about the underlying large-scale circulation which may help to discriminate between precipitation affected by different processes, we introduce here an empirical quantile-quantile mapping method which runs conditioned on the state of the Southern Oscillation Index (SOI), which is accurately predicted by System4 and is known to affect the local climate. Beyond the reduction of model biases, our results show that the SOI-conditioned method yields better ROC skill scores and reliability than the raw model output over the entire region of study, whereas the standard unconditioned implementation provides no added value for any of these metrics. This suggests that conditioning the bias correction on simple but well-simulated large-scale processes relevant to the local climate may be a suitable approach for seasonal forecasting. Yet, further research on the suitability of the application of similar approaches to the one considered here for other regions, seasons and/or variables is needed.

    This comparative study of young adults in an established democracy (America) and transitional democracy (Hong Kong) analyzed the impact of political efficacy on the relationship between Internet/Facebook use on political and civic participation. Regression analyses in both samples showed that Facebook use consistently predicted both types of participation. Moreover, there were significant negative interaction effects of political efficacy and Facebook use on participation, such that the relationship between Facebook use and participation was stronger for those with lower levels of political efficacy. The findings provide cross-cultural support for the argument that social media use among youth can facilitate greater political and civic engagement, particularly for those who perceive that they have limited ability to participate and understand political affairs.

    Full Text Available Romanian political parties’ websites have developed especially after 2000 and have been used to disseminate information about candidates, campaigns and political agendas. Combining the quantitative content analysis with well-known models I will quantify the degree in which the Romanian Social Democratic Party website contributes to informing, connecting, involving, and mobilizing visitors. Another objective of the analysis is to pinpoint the place that websites occupy on the trajectory web 1.0 – web 2.0. The findings show that the political website is used more to inform and less to involve or mobilize visitors and that the SDP website is far from the web 2.0. taking account the virtual practices performed.

    Full Text Available Few studies have systematically examined the rising political and social unrest in the Balkans. This paper investigates the local dynamics and consequences of widespread anti-establishment discontent in Kosovo through the analytical framework of populism. By focusing on the case of Lëvizja Vetëvendosje (LVV, the paper sets out to consider two related questions: the unique populist style of the LVV and the complex reasons behind its electoral breakthrough and continuing support among various groups. Based on a qualitative documentary analysis of the party programme, manifesto, party publications, speeches of the leadership and interviews, the paper finds that the LVV successfully melds a populist political style, leftist/social democratic agenda and contentious politics as a means to disperse its message. The second part of the article offers three arguments to explain its appeal: structural factors (electoral availability and party system, societal dynamics (political and economic dissatisfaction and the agency of the LVV (internal organisation, cohesion and leadership. The article contributes to the thriving literature on populism through a novel empirical scope, and to the literature on Southeast Europe through a focus on local agency, voter preferences and party system.

  18. Fuel for Debate: Three Studies of the Political Mobilization for and against Hydraulic Fracturing in New York State

    Science.gov (United States)

    Dokshin, Fedor Aleksandrovich

    This dissertation uses the context of the unfolding boom in oil and gas production enabled by hydraulic fracturing ("fracking") technology to ask several interrelated questions: What motivates people to oppose or support industrial development? How do material interests interact with political identities to shape political mobilization? What consequences does this political contestation have for policymaking? Three stand-alone articles, each using unique data and methods, provide new evidence for answering these questions. The three studies place a common emphasis on the multiple meanings that fracking has for opponents and supporters of proposed development as well as the alternative structural conditions that give rise to the divergent beliefs and the social networks that facilitate mobilization. The first article, examines the passage of local zoning ordinances prohibiting fracking and identifies spatial and temporal processes that influenced the pattern of ordinance adoption. The second article, looks more closely at political mobilization for and against hydraulic fracturing by examining individual-level data collected from one town's debate over a proposed ban on oil and gas development. The third article uses a large set of public comments to directly examine the meanings that the public attached to hydraulic fracturing and whether residents who live in close proximity to proposed development understood the industry in systematically different terms than individuals who participated in the debate despite facing little or no direct impact from fracking.

    Purpose: Current procedure guidelines for whole body [18F]fluoro-2-deoxy-D-glucose (FDG)-positron emission tomography (PET) state that studies with visible dose extravasations should be rejected for quantification protocols. Our work is focused on the development and validation of methods for estimating extravasated doses in order to correct standard uptake value (SUV) values for this effect in clinical routine. Methods: One thousand three hundred sixty-seven consecutive whole body FDG-PET studies were visually inspected looking for extravasation cases. Two methods for estimating the extravasated dose were proposed and validated in different scenarios using Monte Carlo simulations. All visible extravasations were retrospectively evaluated using a manual ROI based method. In addition, the 50 patients with higher extravasated doses were also evaluated using a threshold-based method. Results: Simulation studies showed that the proposed methods for estimating extravasated doses allow us to compensate the impact of extravasations on SUV values with an error below 5%. The quantitative evaluation of patient studies revealed that paravenous injection is a relatively frequent effect (18%) with a small fraction of patients presenting considerable extravasations ranging from 1% to a maximum of 22% of the injected dose. A criterion based on the extravasated volume and maximum concentration was established in order to identify this fraction of patients that might be corrected for paravenous injection effect. Conclusions: The authors propose the use of a manual ROI based method for estimating the effectively administered FDG dose and then correct SUV quantification in those patients fulfilling the proposed criterion.

  3. Study of the replacement correction factors for ionization chamber dosimetry by Monte Carlo simulations

    Wang, Lilie

    In ionization chamber radiation dosimetry, the introduction of the ion chamber into medium will unavoidably distort the radiation field near the chamber because the chamber cavity material (air) is different from the medium. A replacement correction factor, Prepl was introduced in order to correct the chamber readings to give an accurate radiation dose in the medium without the presence of the chamber. Generally it is very hard to measure the values of Prepl since they are intertwined with the chamber wall effect. In addition, the P repl values always come together with the stopping-power ratio of the two media involved. This makes the problem of determining the P repl values even more complicated. Monte Carlo simulation is an ideal method to investigate the replacement correction factors. In this study, four different methods of calculating the values of Prepl by Monte Carlo simulation are discussed. Two of the methods are designated as 'direct' methods in the sense that the evaluation of the stopping-power ratio is not necessary. The systematic uncertainties of the two direct methods are estimated to be about 0.1-0.2% which comes from the ambiguous definition of the energy cutoff Delta used in the Spencer-Attix cavity theory. The two direct methods are used to calculate the values of P repl for both plane-parallel chambers and cylindrical thimble chambers in either electron beams or photon beams. The calculation results are compared to measurements. For electron beams, good agreements are obtained. For thimble chambers in photon beams, significant discrepancies are observed between calculations and measurements. The experiments are thus investigated and the procedures are simulated by the Monte Carlo method. It is found that the interpretation of the measured data as the replacement correction factors in dosimetry protocols are not correct. In applying the calculation to the BIPM graphite chamber in a 60Co beam, the calculated values of P repl differ from those

    The comparison of implants and correction methods remain controversial in AIS. Excellent frontal and axial correction rates have been reported with all-screw constructs, but at the expense of sagittal alignment, which has a tendency to flatten postoperatively. Posteromedial translation using hybrid constructs seems to preserve and improve thoracic kyphosis (TK), but no series exist to date with a significant number of hypokyphotic patients. In addition, the measures of TK in 2D are often wrong in severe AIS due to axial rotation. The goals of this study were therefore to analyze the 3D radiological outcomes of a group of hypokyphotic AIS patients operated with sublaminar bands. 35 consecutive AIS hypokyphotic patients (T4T12 3D spinal reconstructions were performed preoperatively, postoperatively and at the latest follow-up by an independent observer using SterEOS (EOS imaging, Paris, France), and 2D and 3D measurements were compared. In addition, a new 3D parameter [sagittal shift of the apical vertebra (SSAV)], reflecting the translation of the apical vertebra of the main curve in the patient sagittal plane, was described and reported. The age of the cohort was 16 years and the number of sublaminar bands used for correction averaged 6 (±1.5). T1T12 and T4T12 sagittal Cobb angles appeared to be overestimated on 2D postoperatively (3°, p = 0.002 and 4°, p 3D measurements were kept for the quantitative analysis of the postoperative correction. T4T12 TK significantly increased after surgery (average 8° ± 7°, p 3D T4T12 kyphosis (r = 0.62). Measures in 2D tend to overestimate sagittal alignment and are not sufficient to evaluate postoperative correction. SSAV is a new 3D parameter reflecting the TK change that needs to be further investigated and used in the future. This series confirms that sublaminar bands should be considered in hypokyphotic patients, since thoracic sagittal alignment was restored in 68.6% of the cases.

    2013-01-01

    Full Text Available Abstract Background Many genetic diseases are due to defects in protein trafficking where the mutant protein is recognized by the quality control systems, retained in the endoplasmic reticulum (ER, and degraded by the proteasome. In many cases, the mutant protein retains function if it can be trafficked to its proper cellular location. We have identified structurally diverse correctors that restore the trafficking and function of the most common mutation causing cystic fibrosis, F508del-CFTR. Most of these correctors do not act directly as ligands of CFTR, but indirectly on other pathways to promote folding and correction. We hypothesize that these proteostasis regulators may also correct other protein trafficking diseases. Methods To test our hypothesis, we used stable cell lines or transient transfection to express 2 well-studied trafficking disease mutations in each of 3 different proteins: the arginine-vasopressin receptor 2 (AVPR2, also known as V2R, the human ether-a-go-go-related gene (KCNH2, also known as hERG, and finally the sulfonylurea receptor 1 (ABCC8, also known as SUR1. We treated cells expressing these mutant proteins with 9 structurally diverse F508del-CFTR correctors that function through different cellular mechanisms and assessed whether correction occurred via immunoblotting and functional assays. Results were deemed significantly different from controls by a one-way ANOVA (p  Results Here we show that F508del-CFTR correctors RDR1, KM60 and KM57 also correct some mutant alleles of other protein trafficking diseases. We also show that one corrector, the cardiac glycoside ouabain, was found to alter the glycosylation of all mutant alleles tested. Conclusions Correctors of F508del-CFTR trafficking might have broader applications to other protein trafficking diseases.

    Full Text Available According to Foucault, the uprising of the Iranian people in the seventies reveals how much the political force of Islam is due precisely to the fact that it is not principally located in the field of politics, but in that of ethics. Religion (Shiite Islam appears as the guarantee of real change in the very mode of existence. This spiritual politics is marginalized by Marxism, where it is understood as a discontinuity in relation to proper politics, given that the latter is necessarily linked to a strategic rationalization. By indicating, at this juncture of what is intolerable, the living source and the critical impulse of the Foucauldian ethics, this spiritual politics also leads to recognize in the concept of “subjectivation” a dimension that might escape the circle of freedom as determined by a total immanence to power. This conceptual possibility is highly present in the aporias of the Foucauldian concept of the “relation to oneself”, both as a first condition of governmentality and the ultimate point of resistance against any governmentality. It thus reveals the difficulties in relating political to ethical subjectivation.

  13. A case study in the politics of free-market health care.

    Begun, J W; Lippincott, R C

    1982-01-01

    Historically, most health occupations have developed legal and ethical restrictions on price advertising and other characteristics of "commercial" practice. Many of these regulations recently have come under critical scrutiny, on the grounds that they inhibit free-market health care delivery, thus keeping prices high, and productivity and innovation low. To help inform current health policy deliberations, we analyze the political history of anticompetitive regulations in one health occupation, optometry. Restrictions on commercial practice arose as a result of professional optometry's purge of commercial elements in the 1930s. Optometry's success in achieving commercial-practice restrictions at the state level was determined by the economic structure of the ophthalmic goods and services industry in each state in the 1930s, and by the political resources and organization of the competing interest groups. Efforts to deregulate health occupations will precipate political conflict to the extent that economic interests are threatened. Opposition to deregulation will be based overtly on the grounds that quality of care will deteriorate, and a significant political investment by proponents of free-market health care will be required to overcome such opposition.

    Full Text Available In a number of recent studies we used computer modeling to investigate the evolution of muscle leverage (moment arms and function in extant and extinct archosaur lineages (crocodilians, dinosaurs including birds and pterosaurs. These studies sought to quantify the level of disparity and convergence in muscle moment arms during the evolution of bipedal and quadrupedal posture in various independent archosaur lineages, and in doing so further our understanding of changes in anatomy, locomotion and ecology during the group’s >250 million year evolutionary history. Subsequent work by others has led us to re-evaluate our models, which revealed a methodological error that impacted on the results obtained from the abduction–adduction and long-axis rotation moment arms in our published studies. In this paper we present corrected abduction–adduction and long axis rotation moment arms for all our models, and evaluate the impact of this new data on the conclusions of our previous studies. We find that, in general, our newly corrected data differed only slightly from that previously published, with very few qualitative changes in muscle moments (e.g., muscles originally identified as abductors remained abductors. As a result the majority of our previous conclusions regarding the functional evolution of key muscles in these archosaur groups are upheld.

    Prior research suggests that high school experiences shape young adult political behaviors, particularly among immigrant youth. The U.S. social studies classroom, focused on democratic citizenship education, proves an interesting socializing institution. Through qualitative inquiry, we interviewed Latino immigrant young adults and their former teachers regarding their high school social studies experiences and evolving political and civic engagement. indicate that armed with experience bridging the worlds of the school and home, immigrant students respond and relate to the content and pedagogy of the social studies classroom in such a way that they (1) participate in civic discourse and (2) nurture a disposition toward leadership through teachers' civic expectations of them and instructional emphasis on critical thinking skills. The ability to engage in civic discourse and a disposition toward leadership are both necessary to foster America's democratic ideals, and to take on leadership roles during adulthood. With focused effort on the unique perspective of immigrant youth, high school social studies teachers can nurture in these students the ability to become leaders in young adulthood, broadening the potential leadership pool. This study highlights how the social studies curriculum may be particularly salient to Latino immigrant youth as they transition from adolescence to young adulthood and develop their political and civic identities.

    2006-11-01

    Full Text Available Politics, Law and Psychology are fields that come together in the symbolic. This text takes evidence from those three areas to develop an analysis of political symbols and political transitions. The development of the analysis goes through three stages. The first succinctly describes the concept of transition and its meaning. The second closely examines the notion of the symbol, in terms of its definition, to explain aspects that allow us to understand it, characterise it and make its functions clear. Finally, from the author's experience as a witness and as an actor, I suggest three ways of understanding symbols in the processes of political transition: as symbols of change, as symbols of acknowledgment, and as symbols of support.

    Full Text Available Introduction: Over the past two decades, numerous studies on indoor air and the Sick Building Syndrome (SBS have been conducted, mostly in office environments. However, there is little knowledge about SBS in police officers. This study was aimed to fill this gap. Methods: A cross-sectional questionnaire survey was conducted in 2016 at the Triveneto Penitentiary Center, Northern Italy. Chi-square was used to test the difference of prevalence between office workers (OWs and correctional officers (COs of personal characteristics, cases of SBS, and general and mucocutaneous symptoms associated with SBS. A binary logistic regression was used to identify among individual, environmental, and psychosocial characteristics, factors associated with correctional officers’ Sick Building Syndrome. Results: Chi-squared analyses revealed that there were statistically significant differences in the estimated prevalence of SBS general symptoms (χ2 (1 = 12.22, P < .05, SBS mucocutaneous symptoms (χ2 (1 = 9.04, P < .05, and cases of SBS (χ2 (1 = 4.39, P <.05 between COs and OWs. COs reported that their health had been affected by the passive smoking (β = 2.34, P < .05 and unpleasant odour (β = 2.51, P < .05 as environmental risk factors; work-family conflict (β = 2.14, P < .05, psychological and physical isolation (β = 2.07, P < .05, and negative public image (β = 2.06, P < .05 as psychosocial risk factors. Finally, atopy (β = 2.02, P < .05 and to be current smoker (β = 2.02, P < .05 were statistically significant behavioral predictors of SBS among correctional officers. Discussion: Our survey showed that symptoms compatible with the sick building syndrome are common in correctional officers and that psychosocial work climate and exposure to passive smoking could have a strong influence on the prevalence of both general and mucocutaneous symptoms associated with SBS.

    Chafin, W Sue; Biddle, Wendy L

    2013-04-01

    Retention of nursing staff is more complex in a correctional facility. After a period of 3 years, only 20% of the staff remained employed at this study facility. Without retention of qualified correctional nurses, there are decreases in access to care, gaps in continuity of care, and less time for mentorship. Trained correctional nurses improve patient and staff safety, provide more education, and are more team-oriented. The purpose of this study was to identify barriers and benefits to nursing staff satisfaction with their job and the likelihood that they will continue to work in correctional settings. Practice and patient care will be favorably impacted if correctional nurses are provided with services such as new hire orientation, clinical ladder programs to recruit and retain nursing staff, and teambuilding.

    Full Text Available Is Christian spirituality systematically associated with patterns in people’s political attitudes and worldview? Are spiritually active Christians predominantly conservative or liberal? If so, does this imply anything about the correctness of their political views? Is greater spiritual involvement associated with a friendlier disposition towards those with whom one otherwise strongly disagrees on social and political matters? In my review of the Orthodox spiritual literature, as well as my survey analysis of Orthodox Christians throughout the United States, I make a preliminary effort to address these and other questions. I point to the importance of transcending the liberal-conservative ideological dichotomy when studying Christians’ political outlooks. Communitarians, in particular, merit greater attention, given their apparently large size and high level of spiritual commitment. I also presents findings that suggest that spiritual commitment can result in friendlier attitudes towards those viewed as sociopolitical threats.

  15. Special report on the political and social contexts of health: Part I. Introduction: objectives and purposes of the study.

    Navarro, Vicente

    2003-01-01

    This article introduces a series of research projects (carried out by the International Network on Social Inequalities and Health) focused on the impact of politics on policy and the consequences for health and quality of life, an area that has been understudied in the social science literature. The introduction describes the conceptual model that guided the research, centered on the study of how political parties and social agents (such as trade unions) affect social inequalities and mortality indicators through labor market and welfare state policies. The major theme of this research is whether political and social interventions matter in health policy and health outcomes. The introduction also describes the different types of research projects carried out by the International Network at the national levels (among OECD countries) and at the regional and local levels (in the United Kingdom, Italy, Germany, Spain, and Sweden). This Journal issue presents the multinational study and the U.K. case study; the next issue will include the Italian, German, Spanish, and Swedish case studies and the summary and conclusions.

    2013-01-01

    The American Society of Nuclear Cardiology and the Society of Nuclear Medicine conclude that incorporation of attenuation corrected (AC) images in myocardial perfusion scintigraphy (MPS) will improve diagnostic accuracy. The aim was to investigate the value of adding AC stress-only images for the decision whether a rest study is necessary or not. 1,261 patients admitted to 99m Tc MPS were studied. The stress studies were interpreted by two physicians who judged each study as “no rest study necessary” or “rest study necessary”, by evaluating NC stress-only and NC + AC stress-only images. When there was disagreement between the two physicians, a third physician evaluated the studies. Thus, agreement between 2 out of 3 physicians was evaluated. The physicians assessed 214 more NC + AC images than NC images as “no rest study necessary” (17% of the study population). The number of no-rest-study-required was significantly higher for NC + AC studies compared to NC studies (859 vs 645 cases (p < 0.0001). In the final report according to clinical routine, ischemia or infarction was reported in 23 patients, assessed as “no rest study necessary” (22 NC + AC cases; 8 NC cases), (no statistically significant difference). In 11 of these, the final report stated “suspected/possible ischemia or infarction in a small area”. Adding AC stress-only images to NC stress-only images reduce the number of unnecessary rest studies substantially

  17. A study of the pressure correction approach in the colocated grid arrangement

    1997-12-31

    A pressure correction approach in a collocated grid arrangement is studied. The SIMPLE algorithm has been implemented into a two-dimensional Navier-Stokes solver for incompressible flows. A multigrid Poisson solver for the pressure correction equation is utilized. It has been tested alone and as a part of the Navier- Stokes solver. In the former case. the improvement in the convergence rate is remarkable. As a part of a carefully performed Navier-Stokes computation, the multigrid Poisson solver is able to decrease the total CPU time to one third. Cell-face velocity formulas for the continuity equation are also studied. The solution method is tested using several flow cases including a lid-driven cavity and a buoyancy-driven flow. The Rhie and Chow interpolation method and its simplified and limited versions are compared with each other. The traditional Rhie and Chow interpolation method had problems if the flow field contained a high pressure gradient, which can be overcome by using the two latter versions. For buoyancy-driven flows, a body force term in the cell-face velocity formula has been proposed, but the buoyancy-driven test case (Ra -> 10{sup 9}) indicated that this is not necessary.

    The conflict between technological and political decisions concerning a spent fuel policy is again proclaimed. It is pointed out that this must be a decision at the national level and that new studies on areas already studied is a method of avoiding decisions. The author states that he doubts that ''a policy, capable of implementation within a reasonable time frame,'' can be developed if restrictions are not placed ''upon the political as well as the technical community.''

    This journal's editorial statement is clear that political discourse should be studied not only as regards parliamentary type politics. In this introduction we argue precisely for the need to pay increasing attention to the way that political ideologies are infused into culture more widely...... of power, requires meanings and identities which can hold them in place. We explain the processes by which critical multimodal discourse analysis can best draw out this ideology as it is realized through different semiotics resources. © John Benjamins Publishing Company....

  1. Child health and nutrition in Peru within an antipoverty political agenda: a Countdown to 2015 country case study

    Miller, J

    1997-01-01

    The domain of inquiry for this study was the influence of the American political environmental context on professional and generic care patterns, expressions, and meanings of Czech American immigrants. The purpose of the research was to document, describe, interpret, and analyze the diversities and universalities of professional and generic care for this cultural group, to provide culturally congruent care to Czech Americans, and to explicate the role of politics as an influence on care patterns, health, and well being. The researcher's former transcultural ethnonursing study in Prague, Czechoslovakia in 1991 served as a stimulus for this in-depth study on politics and care. Twelve key and twenty general informants were interviewed. Five major themes were identified. The researcher discovered that the capitalist economic market structure of the United States influenced informant lifeways in all dimensions of Leininger's Theory of Culture Care Diversity and Universality, as depicted in the Sunrise Model. Specific care patterns discovered included care as choice, care as responsibility, and care as helping each other. Findings related to professional and generic care supported researcher predictions that generic culture care patterns would be important to immigrants. Provisions for culturally congruent nursing care were articulated based on research findings.

  3. Politics, markets and EU gas supply security. Case studies of the UK and Germany

    Energy Technology Data Exchange (ETDEWEB)

    Kopp, Sandu-Daniel

    2015-03-01

    Publication in the field of social sciences. Sandu-Daniel Kopp investigates whether carbon reduction targets are compatible with market-driven competition in gas (and power) industries, and whether security of supply is compatible with competitive markets. He examines the policy trade-offs which need to be made between the three different elements, and whether these policy judgements should be economically or politically based. The analysis shows the need for a complex set of politically determined options to protect (competitive) markets from price risks and emergency events and demonstrates that this has thus far failed the policy test. Overall, the author argues that the three major elements of EU energy policy are incompatible in important respects and thereby challenges much of the conventional wisdom of EU and Member State policies of the past decade.

    2006-01-01

    This article examines the processes by which the Anabolic Steroid Control Act of 2004, an act that added steroid precursors such as androstenedione to the list of Schedule III Controlled Substances in the United States, came to pass in both the House of Representatives and the Senate. Grounded theoretically in political economy, the article addresses, in the abstract, how the interplay of political pressures and economic influences stands to affect the actions of public officials, and how "tougher" drug policies-those touted to be more substantive and efficacious than existing regulations-often fail to effect change. The article concludes with implications for those involved in the regulation of anabolic steroids and steroid precursors.

  6. The political and social barriers for contraception in pest birds: a case study of Ovocontrol (nicarbazin).

    MacDonald, Alexander; Wolf, Erick

    2013-12-01

    In a joint program, Innolytics and the U.S. Department of Agriculture/Animal and Plant Health Inspection Service National Wildlife Research Center collaborated in the development of nicarbazin as an avian contraceptive, initially for resident Canada geese and subsequently for feral pigeons. Unfortunately, the introduction of the original goose product in 2005 was a commercial failure. Political and social barriers effectively thwarted attempts to establish the new technology with any meaningful market success. Although the market adoption of the pigeon contraceptive has been less difficult, the product still encounters significant social and political obstacles and opposition. Given the focus on instant results and gratification, the introduction of contraceptive technology for birds has been challenging and broad market acceptance remains elusive. Nevertheless, especially for short-lived and rapidly reproducing species, customers continue to replace outdated or ineffective techniques with the safer and more effective contraceptive tool.

  7. Theoretical and methodological bases of studying the symbolization of social and political reality in transit societies

    O. V. Slavina

    2014-10-01

    Full Text Available This article is an attempt to form a methodological foundation to explore the process of symbolic constructioning of reality in the political systems in a state of democratic transition. From the author’s point of view, such transit systems differ with the phenomenal features of transitional type of sign-symbolic context. There are the most significant of them: the confrontation of symbols of old and new, and the formation of public anxiety due to violation of the established values (significant symbols. The result of these processes is the emergence of the conditions for increasing capacity of perception of new symbols (re-symbolization, transmigration of symbolic forms, the appearance of spontaneous symbolic interactions in the community in the form of political protests, rallies, and panic. In this regard, it is necessary to understand the possibilities of the productive management of the collective consciousness in transit period to achieve mental solidarity of concrete society with democratic values. To perform this task, author develops the appropriate tools, which are based on the phenomenological theory, the Schutz’s theory of the constitution of the multiple realities, the philosophy of symbolic forms of E. Cassirer, the theory of social construction of P. Berger and T. Luckmann, as well as Lotman’s semiotic concept. It is concluded that in the collision of alternative symbolic projects of social order it is advisable to resort to controlled symbolization (the production of special symbolic codes of political legitimation. At the same time it is important to understand the mechanisms of auto- symbolization of the society (changing of mass consciousness by virtue of the progressive development of the political culture of people. Careless use of these technologies in the countries with non-consolidated democracy may become a factor of destabilization and formation of the conditions for authoritarian rollback.

    Mendelian randomization studies use genotypes as instrumental variables to test for and estimate the causal effects of modifiable risk factors on outcomes. Two-stage residual inclusion (TSRI) estimators have been used when researchers are willing to make parametric assumptions. However, researchers are currently reporting uncorrected or heteroscedasticity-robust standard errors for these estimates. We compared several different forms of the standard error for linear and logistic TSRI estimates in simulations and in real-data examples. Among others, we consider standard errors modified from the approach of Newey (1987), Terza (2016), and bootstrapping. In our simulations Newey, Terza, bootstrap, and corrected 2-stage least squares (in the linear case) standard errors gave the best results in terms of coverage and type I error. In the real-data examples, the Newey standard errors were 0.5% and 2% larger than the unadjusted standard errors for the linear and logistic TSRI estimators, respectively. We show that TSRI estimators with modified standard errors have correct type I error under the null. Researchers should report TSRI estimates with modified standard errors instead of reporting unadjusted or heteroscedasticity-robust standard errors. © The Author(s) 2017.

    Ekstrom, Pierce D; Federico, Christopher M

    2018-05-27

    To investigate how the relations between the Big Five personality traits and political preferences develop over a campaign. We rely on a 6-wave nationwide longitudinal survey from the 2008 U.S. election that included 20,000 respondents. Mean age: 49 (SD=15). 53% of respondents were women, 47% men. 82% were White, 8% Black, 6% Hispanic/Latino, 1% Asian, 1% Native American, and 2% other. Survey weights were applied to approximate a representative sample of the U.S. Ns for reported analyses range from 5,160 to 12,535. First, conscientiousness and openness to experience were significantly associated with changes in outcomes over time, such that individuals higher in conscientiousness and lower in openness tended to become more conservative, identify as more Republican, and evaluate John McCain more favorably relative to Barack Obama. Second, the effects of personality on candidate evaluations were mediated by partisanship and ideology. Finally, we find that the relations between traits and late-campaign candidate evaluations are stronger than those between traits and early-campaign candidate evaluations. Personality plays an important and dynamic role in the formation and change of political preferences over the course of political campaigns-a role which is not entirely visible in cross-sectional analyses.

  12. Predator Politics

    Directory of Open Access Journals (Sweden)

    Mary Louisa Cappelli

    2017-01-01

    Full Text Available Edward Abbey’s Desert Solitaire and Barbara Kingsolver’s Prodigal Summer urges readers to see coyotes as crucial members of the natural community whose predation is essential for the maintenance of biodiversity and ecological stability. Their cultural production provides a human story of ecocritical engagement for understanding the cascading effects of removing top predators from their ecosystems. By envisioning biocentric possibilities within place-based and scientific contexts, Edward Abbey and Barbara Kingsolver share a common theme of political ecology: political processes shape ecological conditions. A close reading of Edward Abbey’s Desert Solitaire and Barbara Kingsolver’s Prodigal Summer provides a literary entryway to connect research, arguments, and discourse across disciplines tasking readers to engage in political discussions of environmental sustainability and to consider viable solutions to preserve the ecological diversity of our predator populations and ecosystems.

  13. Alternative Forms of Energy Production and Political Reconfigurations: The Sociology of Alternative Energies as a Study of Collective Reorganization Potential

    2013-01-01

    Energy choices that are made in a society are also political choices. This article aims to study the extent to which these choices can be reoriented by technological developments related to renewable energies, thus contributing to a redistribution of possibilities and to social reorganization. Three steps are proposed to show that while the development of alternative energies depends on technological advances, it can, in this process, also reveal political potentials: 1) the first step clarifies the theoretical arguments that can be deployed in favour of an approach in terms of 'technological potentialism'; 2) the second step extends this approach by identifying a set of potentials linked to renewable energies and the model that could take shape through these alternative forms; 3) the third step examines how these potentials could find ways of being updated

    In this study, atmospheric radiative transfer model 6S was used to simulate the radioactive transfer process in the surface-atmosphere-sensor. An algorithm based on the look-up table (LUT) founded by 6S model was used to correct (HJ-1) CCD image pixel by pixel. Then, the effect of atmospheric correction on CCD data of HJ-1 satellite was analyzed in terms of the spectral curves and evaluated against the measured reflectance acquired during HJ-1B satellite overpass, finally, the normalized difference vegetation index (NDVI) before and after atmospheric correction were compared. The results showed: (1) Atmospheric correction on CCD data of HJ-1 satellite can reduce the ''increase'' effect of the atmosphere. (2) Apparent reflectance are higher than those of surface reflectance corrected by 6S model in band1∼band3, but they are lower in the near-infrared band; the surface reflectance values corrected agree with the measured reflectance values well. (3)The NDVI increases significantly after atmospheric correction, which indicates the atmospheric correction can highlight the vegetation information

    Head motion is difficult to avoid in long PET studies, degrading the image quality and offsetting the benefit of using a high-resolution scanner. As a potential solution in an integrated MR-PET scanner, the simultaneously acquired MR data can be used for motion tracking. In this work, a novel data processing and rigid-body motion correction (MC) algorithm for the MR-compatible BrainPET prototype scanner is described and proof-of-principle phantom and human studies are presented. Methods To account for motion, the PET prompts and randoms coincidences as well as the sensitivity data are processed in the line or response (LOR) space according to the MR-derived motion estimates. After sinogram space rebinning, the corrected data are summed and the motion corrected PET volume is reconstructed from these sinograms and the attenuation and scatter sinograms in the reference position. The accuracy of the MC algorithm was first tested using a Hoffman phantom. Next, human volunteer studies were performed and motion estimates were obtained using two high temporal resolution MR-based motion tracking techniques. Results After accounting for the physical mismatch between the two scanners, perfectly co-registered MR and PET volumes are reproducibly obtained. The MR output gates inserted in to the PET list-mode allow the temporal correlation of the two data sets within 0.2 s. The Hoffman phantom volume reconstructed processing the PET data in the LOR space was similar to the one obtained processing the data using the standard methods and applying the MC in the image space, demonstrating the quantitative accuracy of the novel MC algorithm. In human volunteer studies, motion estimates were obtained from echo planar imaging and cloverleaf navigator sequences every 3 seconds and 20 ms, respectively. Substantially improved PET images with excellent delineation of specific brain structures were obtained after applying the MC using these MR-based estimates. Conclusion A novel MR-based MC

    Full Text Available This article starts by identifying the crucial importance of the notion of historical handicap for the present-day social sciences of Latin America. Such notion is not an original invention made by Latinamericanists. On the contrary, I demonstrate that the genealogy of the notion of historical handicap must be sought in the tradition of Western political philosophy. Such genealogy must take into account the way it was integrated into ethnological descriptions. When and how did the Other become the backward, the primitive? While this relation was secondary for ancient Greek thought, theories of historical development became the main source of ethnological categories in the modern era. Interestingly enough, this modern synthesis suited the practical purpose of justifying two successive waves of European imperialistic: the era of discoveries, and 19th century colonialism. The article concludes by raising questions about the present role and application of the social sciences.Esse artigo começa por identificar o papel central da noção de incapacidade histórica para a literatura de Latin American studies produzida no pós-guerra. Tal noção não foi criada pelos Latinoamericanistas contemporâneos. É possível identificar o embrião da noção de incapacidade histórica nos mitos primitivistas da antiguidade clássica e, a partir daí, examinar as várias maneiras com que ela foi recebida e rearticulada pela tradição filosófica ocidental. Esse estudo é feito tendo em vista a incorporação da noção de incapacidade histórica a teorias etnológicas. Quando e como o "outro" passou a ser visto como o "atrasado", o "primitivo"? Se na antiguidade clássica essa identificação era incompleta, na era moderna teorias de desenvolvimento histórico se tornaram a fonte principal de categorias etnológicas. É importante notar que a síntese moderna dessas teorias também serviram para justificar as aventuras imperialistas Européias: a era dos

  19. Perceptions of political leaders.

    Science.gov (United States)

    David Schmitz, J; Murray, Gregg R

    2017-01-01

    Partisan identification is a fundamental force in individual and mass political behavior around the world. Informed by scholarship on human sociality, coalitional psychology, and group behavior, this research argues that partisan identification, like many other group-based behaviors, is influenced by forces of evolution. If correct, then party identifiers should exhibit adaptive behaviors when making group-related political decisions. The authors test this assertion with citizen assessments of the relative physical formidability of competing leaders, an important adaptive factor in leader evaluations. Using original and novel data collected during the contextually different 2008 and 2012 U.S. presidential elections, as well as two distinct measures obtained during both elections, this article presents evidence that partisans overestimate the physical stature of the presidential candidate of their own party compared with the stature of the candidate of the opposition party. These findings suggest that the power of party identification on political behavior may be attributable to the fact that modern political parties address problems similar to the problems groups faced in human ancestral times.

    This preliminary qualitative study evaluates the efficacy of cup suction in the correction of pectus excavatum (PE), and examines the place of this system as a strategic treatment and as an alternative to surgery. Between October 2011 and June 2014, a total of 84 patients (children and adult) presenting with PE were treated by cup suction, in our chest wall deformities unit. On first consultation, the patients with typical PE and with at least partial correction during the first application of cup suction and a maximal suction pressure for correction of less than 300 mbar (millibars) were included in this study. 11 patients were excluded from the present study as they presented with a complex carinatum/excavatum. The remaining 73 patients were divided into two groups: Group I, adult patients ≥ 18 year old, 17 patients. The mean age was 22.8 years old. Group II, pediatric patients cup suction, strengthening exercises, and clinical follow-up every two to three months. The evaluation criteria during, and on the completion of the trial were: depth of the PE, morbidity and treatment compliance. Partial and final results were evaluated by the patients, their parents, and doctor, using a qualitative scoring scale. A total of 73 patients presenting typical PE (symmetric in 52 cases and asymmetric in 21 cases) were treated by cup suction. The mean depth of PE was 23 mm (9-44). Of the 73 patients, one adult abandoned treatment and three children abandoned follow-up. The mean time of use of the device was 4h daily. At six months of treatment, the mean depth of PE was 9 mm (0-30) across all patients. 23 patients completed the treatment and exhibited flattening of the sternum. These patients were considered to have an excellent aesthetic result. The mean treatment duration to normal reshape was achieved at 10 months (4-21). The remaining patients are improving under continuing active treatment. The mean depth of PE in this group was 12 mm (4-30), after a mean treatment

    Purpose: The aim of this study was to determine fluence corrections necessary to convert absorbed dose to graphite, measured by graphite calorimetry, to absorbed dose to water. Fluence corrections were obtained from experiments and Monte Carlo simulations in low- and high-energy proton beams. Methods: Fluence corrections were calculated to account for the difference in fluence between water and graphite at equivalent depths. Measurements were performed with narrow proton beams. Plane-parallel-plate ionization chambers with a large collecting area compared to the beam diameter were used to intercept the whole beam. High- and low-energy proton beams were provided by a scanning and double scattering delivery system, respectively. A mathematical formalism was established to relate fluence corrections derived from Monte Carlo simulations, using the FLUKA code [A. Ferrari et al., “FLUKA: A multi-particle transport code,” in CERN 2005-10, INFN/TC 05/11, SLAC-R-773 (2005) and T. T. Böhlen et al., “The FLUKA Code: Developments and challenges for high energy and medical applications,” Nucl. Data Sheets 120, 211–214 (2014)], to partial fluence corrections measured experimentally. Results: A good agreement was found between the partial fluence corrections derived by Monte Carlo simulations and those determined experimentally. For a high-energy beam of 180 MeV, the fluence corrections from Monte Carlo simulations were found to increase from 0.99 to 1.04 with depth. In the case of a low-energy beam of 60 MeV, the magnitude of fluence corrections was approximately 0.99 at all depths when calculated in the sensitive area of the chamber used in the experiments. Fluence correction calculations were also performed for a larger area and found to increase from 0.99 at the surface to 1.01 at greater depths. Conclusions: Fluence corrections obtained experimentally are partial fluence corrections because they account for differences in the primary and part of the secondary

    Aims Baseline HbA1c is a major predictor of response to glucose lowering therapy and therefore a potential confounder in studies aiming to identify other predictors. However, baseline adjustment may introduce error if the association between baseline HbA1c and response is substantially due to measurement error and regression to the mean. We aimed to determine whether studies of predictors of response should adjust for baseline HbA1c. Methods We assessed the relationship between baseline HbA1c and glycaemic response in 257 participants treated with GLP-1R agonists and assessed whether it reflected measurement error and regression to the mean using duplicate ‘pre-baseline’ HbA1c measurements not included in the response variable. In this cohort and an additional 2659 participants treated with sulfonylureas we assessed the relationship between covariates associated with baseline HbA1c and treatment response with and without baseline adjustment, and with a bias correction using pre-baseline HbA1c to adjust for the effects of error in baseline HbA1c. Results Baseline HbA1c was a major predictor of response (R2 = 0.19,β = -0.44,pHbA1c were associated with response, however these associations were weak or absent after adjustment for baseline HbA1c. Bias correction did not substantially alter associations. Conclusions Adjustment for the baseline HbA1c measurement is a simple and effective way to reduce bias in studies of predictors of response to glucose lowering therapy. PMID:27050911

    While positron emission tomographic (PET) measurements of regional cerebral blood flow (rCBF) can be used to map brain regions that are involved in normal and pathological human behaviors, measurements in the anteromedial temporal lobe can be confounded by the combined effects of radiotracer activity in neighboring arteries and partial-volume averaging. The authors now describe two simple methods to address this vascular artifact. One method utilizes the early frames of a dynamic PET study, while the other method utilizes a coregistered magnetic resonance image (MRI) to characterize the vascular region of interest (VROI). Both methods subsequently assign a common value to each pixel in the VROI for the control (baseline) scan and the activation scan. To study the vascular artifact and to demonstrate the ability of the proposed methods correcting the vascular artifact, four dynamic PET scans were performed in a single subject during the same behavioral state. For each of the four scans, a vascular scan containing vascular activity was computed as the summation of the images acquired 0-60 s after radiotracer administration, and a control scan containing minimal vascular activity was computed as the summation of the images acquired 20-80 s after radiotracer administration. t-score maps calculated from the four pairs of vascular and control scans were used to characterize regional blood flow differences related to vascular activity before and after the application of each vascular artifact correction method. Both methods eliminated the observed differences in vascular activity, as well as the vascular artifact observed in the anteromedial temporal lobes. Using PET data from a study of normal human emotion, these methods permitted the authors to identify rCBF increases in the anteromedial temporal lobe free from the potentially confounding, combined effects of vascular activity and partial-volume averaging.

    Memory researchers have long been captivated by the nature of memory distortions and have made efforts to identify the neural correlates of true and false memories. However, the underlying mechanisms of avoiding false memories by correctly rejecting related lures remains underexplored. In this study, we employed a variant of the Deese/Roediger-McDermott paradigm to explore neural signatures of committing and avoiding false memories. ERP were obtained for True recognition, False recognition, Correct rejection of new items, and, more importantly, Correct rejection of related lures. With these ERP data, early-frontal, left-parietal, and late right-frontal old/new effects (associated with familiarity, recollection, and monitoring processes, respectively) were analysed. Results indicated that there were similar patterns for True and False recognition in all three old/new effects analysed in our study. Also, False recognition and Correct rejection of related lures activities seemed to share common underlying familiarity-based processes. The ERP similarities between False recognition and Correct rejection of related lures disappeared when recollection processes were examined because only False recognition presented a parietal old/new effect. This finding supported the view that actual false recollections underlie false memories, providing evidence consistent with previous behavioural research and with most ERP and neuroimaging studies. Later, with the onset of monitoring processes, False recognition and Correct rejection of related lures waveforms presented, again, clearly dissociated patterns. Specifically, False recognition and True recognition showed more positive going patterns than Correct rejection of related lures signal and Correct rejection of new items signature. Since False recognition and Correct rejection of related lures triggered familiarity-recognition processes, our results suggest that deciding which items are studied is based more on recollection

    Cervical spine injuries sustained in rear-end crashes cost at least $7 billion in insurance claims annually in the United States alone. When positioned correctly, head restraint systems have been proven effective in reducing the risk of whiplash associated disorders. Chiropractors should be knowledgeable about the correct use of head restraint systems to educate their patients and thereby prevent or minimize such injuries. The primary objective of this study was to determine the prevalence of correct positioning of car seat head restraints among the interns at our institution. The secondary objective was to determine the same chiropractic interns' knowledge of the correct positioning of car seat head restraints. It was hypothesized that 100 percent of interns would have their head restraint correctly positioned within an acceptable range and that all interns would possess the knowledge to instruct patients in the correct positioning of head restraints. Cross-sectional study of a convenient sample of 30 chiropractic interns from one institution. Interns driving into the parking lot of our health center were asked to volunteer to have measurements taken and to complete a survey. Vertical and horizontal positions of the head restraint were measured using a beam compass. A survey was administered to determine knowledge of correct head restraint position. The results were recorded, entered into a spreadsheet, and analyzed. 13.3 percent of subjects knew the recommended vertical distance and only 20 percent of subjects knew the recommended horizontal distance. Chi Square analyses substantiated that the majority of subjects were unaware of guidelines set forth by the National Highway Traffic Safety Administration (NHTSA) for the correct positioning of the head restraint (chi(2) (vertical) = 16.13, chi(2) (horizontal) = 10.80, p .05). Interestingly, the 13.3 percent of the subjects who were aware of the vertical plane recommendations did not correctly position their own

    This paper describes a conceptual design study for the circuit configuration of the Error Field Correction Coil (EFCC) power supply (PS) to maximize the expected performance with reasonable cost in JT-60SA. The EFCC consists of eighteen sector coils installed inside the vacuum vessel, six in the toroidal direction and three in the poloidal direction, each one rated for 30 kA-turn. As a result, star point connection is proposed for each group of six EFCC coils installed cyclically in the toroidal direction for decoupling with poloidal field coils. In addition, a six phase inverter which is capable of controlling each phase current was chosen as PS topology to ensure higher flexibility of operation with reasonable cost.

    2005-01-01

    The coincidence Doppler broadening (CDB) technique was applied to study the electron momentum distribution in anthracene, diphenyl, naphthalene, and polystyrene. A method for separation of the positron and positronium (Ps) components from the Doppler-broadened annihilation line (DBAL) was developed further to be applicable to hydrocarbons with different π and σ valence electron distributions. This method allows extraction of the electron momentum distribution (EMD) from DBAL for samples when Ps formation occurs. The annihilation on π valence electrons was detected as broadening of the EMD compared to that obtained for a polymer sample only with σ valence electrons. The broadening appeared as a significant change in the shape of the CDB ratio of the corresponding positronium-corrected curves: a slight enhancement above the unity line in the low-momentum region and a drop in the momentum region, 10-20x10 -3 m o c

    Full Text Available Relevance. Lack of iodine in the environment is one of the topical medico-social problems in many countries of the world. Iodine deficiency is an important risk factor for the developmental delay, memory loss, or the ability for analysis and abstract thinking. Traditionally in Ukraine the problem of iodine deficiency was relevant in Western regions, but recent studies indicate the existence of moderate iodine deficiency in all areas. The aim of our study was to assess the iodine status of primary schoolchildren from Kyiv. Materials and methods. The examination of 52 children aged 6–12 years was performed, which involved a survey of families on awareness of the consequences of iodine deficiency and frequency of consumption of foods containing iodine, objective and ultrasound thyroid investigation, determination of urine iodine content in single portions of urine. Results. Iodine deficiency was detected in 87 % of pupils, mostly mild. Diffuse goiter grade 1 was diagnosed in 23 % of patients. To correct iodine deficiency, we have used new generation product — jodis-concentrate as an aqueous solution. Conclusions. Research of iodine status in schoolchildren aged 6–12 years in Kyiv showed the presence of mild iodine deficiency in 87 % of them (in 68 and 19 %, respectively. In 12 (23 % children, we have diagnosed thyroid volume increase under normal echogenicity and homogeneous echostructure. Lack of iodine nutrition is caused by poor nutrition, lack of mass, group and individual iodine prophylaxis, low sanitary hygienic culture of the population. Pupils with iodine deficiency were administered an individual subsidy of iodine in the form of an aqueous solution of jodis-concentrate for 12 months, which has significantly improved the iodine status of children, normalized the level of urine iodine content. Early detection of iodine deficiency and its correction are the promising directions of modern pediatrics in terms of the prevention of thyroid

    The Correction of Myopia Evaluation Trial (COMET), a multicentre clinical trial based in 4 schools of optometry in the United States, evaluated the effect of progressive addition lenses versus single vision lenses on myopia progression in an ethnically diverse group of 469 myopic children aged 6 to 11 years. Completion of the clinical trial phase of the study provides an opportunity to evaluate aspects of the study design that contribute to its success. This article describes aspects of the study design that were influential in ensuring the smooth conduct of COMET. These include a dedicated team of investigators, an organisational structure with strong leadership and an independent Co-ordinating Centre, regular communication among investigators, flexible and creative approaches to recruitment and retention, sensitivity to concerns for child safety and child participation, and methods for enhancing and monitoring data reliability. The experience with COMET has provided a number of valuable lessons for all aspects of the study design that should benefit the development and implementation of future clinical trials, particularly those done in similar populations of children. The use of a carefully designed protocol using standard methods by dedicated members of the study team is essential in ensuring achievement of the study aims.

    This study investigated the cognitive processing of true and false political information. Specifically, it examined the impact of source credibility on the assessment of veracity when information comes from a polarizing source (Experiment 1), and effectiveness of explanations when they come from one's own political party or an opposition party (Experiment 2). These experiments were conducted prior to the 2016 Presidential election. Participants rated their belief in factual and incorrect statements that President Trump made on the campaign trail; facts were subsequently affirmed and misinformation retracted. Participants then re-rated their belief immediately or after a delay. Experiment 1 found that (i) if information was attributed to Trump, Republican supporters of Trump believed it more than if it was presented without attribution, whereas the opposite was true for Democrats and (ii) although Trump supporters reduced their belief in misinformation items following a correction, they did not change their voting preferences. Experiment 2 revealed that the explanation's source had relatively little impact, and belief updating was more influenced by perceived credibility of the individual initially purporting the information. These findings suggest that people use political figures as a heuristic to guide evaluation of what is true or false, yet do not necessarily insist on veracity as a prerequisite for supporting political candidates.

    Full Text Available In March 2014 a change took place on Europe's political map. The Crimean Peninsula became part of Russia, switching sovereignty after more than 20 years during which it was part of Ukraine. This took place following a Russian military intervention and a referendum. A majority of the world's countries however, do not recognize the Russian control of Crimea and still consider it a part of Ukraine, rendering the territory an area with undefined political status. Shortly after the sovereignty change, the region and its population started experiencing all kinds of hardships. An often neglected type of hardship Crimeans are experiencing is the difficulty of obtaining visas. Following the referendum, many diplomatic missions in Russia have instituted a policy of not issuing visas to residents of Crimea who apply with Russian-issued documents. This article shall make a summary of EU and Schengen countries' positions regarding this issue, as these are the biggest groups of countries that requires both Russians and Ukrainians to obtain visas before travelling there. This research was made mostly directly, by requesting each country's diplomatic mission in Moscow to give an official position. The research had the purpose of verifying the information that certain countries do issue visas to Crimeans with Russian documents and also to give a more general and complex picture on the matter of visas for residents of Crimea. This theme is important as a policy of not issuing visas has significant repercussions on the region's economy and on the freedom of movement of its citizens.

    Politics and policy affect all of us, both as scientists and as citizens, and issues ranging from laboratory budgets to arms control treaties clearly require research problem-solving skills and technical expertise. There is a critical role for scientists in each aspect of the political system, and in fact, we as a society need more scientists to take part in politics. Furthermore, the research we pursue has important societal applications and is fascinating! We have a right and a responsibility to share our scientific knowledge not only with each other, but with the general public as well. So, why are we as a community of scientists reticent in the public arena, hesitant to enter politics, and even at times unsupportive of our peers who transition into governmental roles? In this time of fiscal constraint, when difficult research funding (and de-funding) choices are regularly being made, we as scientists must step up to the plate, reach across the aisle, and explain why what we do is fascinating, inspiring, and important, not just to us, but to society as a whole. A range of policy-relevant roles exists inside and outside the laboratory, such as Congressional Fellowships. Each year the Congressional Fellowships program brings together approximately thirty scientists at all stages of their careers to serve as scientific advisors in a variety of offices in the U.S. Senate and House of Representatives. Although the jump from lab to lobbying meetings can be frustrating, the transition can also be intriguing. Firsthand experience with the ``how'' and ``why'' (or lack thereof) of politics and policy is invaluable and provides a unique opportunity to expand and broaden one's background. The opportunity to work on Capitol Hill is unparalleled, particularly because our nation has a definite need for scientists with the inclination and interest to inform and develop policy. But, whatever role you decide to take, from contributing scientific news to local publications to

  12. Monte Carlo study of correction factors for the use of plastic phantoms in clinical electron dosimetry

    In some recent dosimetry protocols, plastic is allowed as a phantom material for the determination of an absorbed dose to water in electron beams, especially for low energy with beam qualities R 50 2 . In electron dosimetry with plastic, a depth-scaling factor, c pl , and a chamber-dependent fluence correction factor, h pl , are needed to convert the dose measured at a water-equivalent reference depth in plastic to a dose at a reference depth in water. The purpose of this study is to calculate correction factors for the use of plastic phantoms for clinical electron dosimetry using the EGSnrc Monte Carlo code system. RMI-457 and WE-211 were investigated as phantom materials. First the c pl values for plastic materials were calculated as a function of a half-value depth of maximum ionization, I 50 , in plastic. The c pl values for RMI-457 and WE-211 varied from 0.992 to 1.002 and from 0.971 to 0.979, respectively, in a range of nominal energies from 4 MeV to 18 MeV, and varied slightly as a function of I 50 in plastic. Since h pl values depend on the wall correction factor, P wall , of the chamber used, they are evaluated using a pure electron fluence correction factor, φ pl w , and P wall w and P wall pl for a combination of water or plastic phantoms and plane-parallel ionization chambers (NACP-02, Markus and Roos). The φ pl w and P wall (P wall w and P wall pl ) values were calculated as a function of the water-equivalent depth in plastic materials and at a reference depth as a function of R 50 in water, respectively. The φ pl w values varied from 1.024 at 4 MeV to 1.013 at 18 MeV for RMI-457, and from 1.025 to 1.016 for WE-211. P wall w values for plane-parallel chambers showed values in the order of 1.5% to 2% larger than unity at 4 MeV, consistent with earlier results. The P wall pl values of RMI-457 and WE-211 were close to unity for all the energy beams. Finally, calculated h pl values of RMI-457 ranged from 1.009 to 1.005, from 1.010 to 1.003 and from 1

    We introduce a simple correction to the calculation of the lattice constants of fully occupied structure sI methane or carbon dioxide pure hydrates that are obtained from classical molecular dynamics simulations using the TIP4PQ/2005 water force field. The obtained corrected lattice constants are subsequently used in order to obtain isobaric thermal expansion coefficients of the pure gas hydrates that exhibit a trend that is significantly closer to the experimental behavior than previously reported classical molecular dynamics studies.

  14. Correction of population stratification in large multi-ethnic association studies.

    Full Text Available The vast majority of genetic risk factors for complex diseases have, taken individually, a small effect on the end phenotype. Population-based association studies therefore need very large sample sizes to detect significant differences between affected and non-affected individuals. Including thousands of affected individuals in a study requires recruitment in numerous centers, possibly from different geographic regions. Unfortunately such a recruitment strategy is likely to complicate the study design and to generate concerns regarding population stratification.We analyzed 9,751 individuals representing three main ethnic groups - Europeans, Arabs and South Asians - that had been enrolled from 154 centers involving 52 countries for a global case/control study of acute myocardial infarction. All individuals were genotyped at 103 candidate genes using 1,536 SNPs selected with a tagging strategy that captures most of the genetic diversity in different populations. We show that relying solely on self-reported ethnicity is not sufficient to exclude population stratification and we present additional methods to identify and correct for stratification.Our results highlight the importance of carefully addressing population stratification and of carefully "cleaning" the sample prior to analyses to obtain stronger signals of association and to avoid spurious results.

    Full Text Available This study attempts to describe the Turkish political market and determine where and how Turkish political parties are perceived by voters. The study uses a two-dimensional map to determine the voter perceptions of the parties in the Turkish political market based on a survey questionnaire applied to 400 young voters. It also investigates whether there are any major differences in the perception of parties in the political space based on voter ideologies. The study finds that young voters have clear perceptions of the positions of Turkish parties. It also finds that voter perceptions of parties vary based on voters’ ideological positions.

    Low cardiac output syndrome commonly complicates the postoperative course after open-heart surgery in children. To prevent low cardiac output syndrome, prophylactic administration of milrinone after cardiopulmonary bypass is commonly used in small children. The aim of this study was to compare the effect of prophylactically administered levosimendan and milrinone on cardiac index in neonates and infants after corrective open-heart surgery. Prospective, single-center, double-blind, randomized pilot study. Tertiary care center, postoperative pediatric cardiac intensive care unit. After written informed consent, 40 infants undergoing corrective open-heart surgery were included. At weaning from cardiopulmonary bypass, either a 24-hr infusion of 0.1 μg/kg/min levosimendan or of 0.5 μg/kg/min milrinone were administered. Cardiac output was evaluated at 2, 6, 9, 12, 18, 24, and 48 hrs after cardiopulmonary bypass using a transesophageal Doppler technique (Cardio-QP, Deltex Medical, Chichester, UK). Cardiac index was calculated from cardiac output and the patients' respective body surface area. Intention-to-treat data of 39 patients (19 in the levosimendan and 20 in the milrinone group) were analyzed using analysis of variance for repeated measurements for statistics. Analysis of variance revealed for both, cardiac index and cardiac output, similar results with no significant differences of the factors group and time. A significant interaction for cardiac output (p = .005) and cardiac index (p = .007) was found, which indicates different time courses of cardiac index in the two groups. Both drugs were well tolerated; no death or serious adverse event occurred. In our small study, postoperative cardiac index over time was similar in patients with prophylactically administered levosimendan and patients with prophylactically given milrinone. We observed an increase in cardiac output and cardiac index over time in the levosimendan group, whereas cardiac output and cardiac

    Head motion is difficult to avoid in long PET studies, degrading the image quality and offsetting the benefit of using a high-resolution scanner. As a potential solution in an integrated MR-PET scanner, the simultaneously acquired MRI data can be used for motion tracking. In this work, a novel algorithm for data processing and rigid-body motion correction (MC) for the MRI-compatible BrainPET prototype scanner is described, and proof-of-principle phantom and human studies are presented. To account for motion, the PET prompt and random coincidences and sensitivity data for postnormalization were processed in the line-of-response (LOR) space according to the MRI-derived motion estimates. The processing time on the standard BrainPET workstation is approximately 16 s for each motion estimate. After rebinning in the sinogram space, the motion corrected data were summed, and the PET volume was reconstructed using the attenuation and scatter sinograms in the reference position. The accuracy of the MC algorithm was first tested using a Hoffman phantom. Next, human volunteer studies were performed, and motion estimates were obtained using 2 high-temporal-resolution MRI-based motion-tracking techniques. After accounting for the misalignment between the 2 scanners, perfectly coregistered MRI and PET volumes were reproducibly obtained. The MRI output gates inserted into the PET list-mode allow the temporal correlation of the 2 datasets within 0.2 ms. The Hoffman phantom volume reconstructed by processing the PET data in the LOR space was similar to the one obtained by processing the data using the standard methods and applying the MC in the image space, demonstrating the quantitative accuracy of the procedure. In human volunteer studies, motion estimates were obtained from echo planar imaging and cloverleaf navigator sequences every 3 s and 20 ms, respectively. Motion-deblurred PET images, with excellent delineation of specific brain structures, were obtained using these 2 MRI

  20. Length bias correction in one-day cross-sectional assessments - The nutritionDay study.

    2016-04-01

    A major problem occurring in cross-sectional studies is sampling bias. Length of hospital stay (LOS) differs strongly between patients and causes a length bias as patients with longer LOS are more likely to be included and are therefore overrepresented in this type of study. To adjust for the length bias higher weights are allocated to patients with shorter LOS. We determined the effect of length-bias adjustment in two independent populations. Length-bias correction is applied to the data of the nutritionDay project, a one-day multinational cross-sectional audit capturing data on disease and nutrition of patients admitted to hospital wards with right-censoring after 30 days follow-up. We applied the weighting method for estimating the distribution function of patient baseline variables based on the method of non-parametric maximum likelihood. Results are validated using data from all patients admitted to the General Hospital of Vienna between 2005 and 2009, where the distribution of LOS can be assumed to be known. Additionally, a simplified calculation scheme for estimating the adjusted distribution function of LOS is demonstrated on a small patient example. The crude median (lower quartile; upper quartile) LOS in the cross-sectional sample was 14 (8; 24) and decreased to 7 (4; 12) when adjusted. Hence, adjustment for length bias in cross-sectional studies is essential to get appropriate estimates. Copyright © 2015 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

  2. Media Coverage of Alcohol Issues: A Critical Political Economy Framework-A Case Study from Ireland.

    There is a growing literature on news media representations of alcohol-related issues. However, current scholarship has neglected critical political economic frameworks to interpret media coverage of alcohol. This paper presents such a framework that conceives of news organisations as corporations that share the values and interests of political and economic elites. The media are thus expected to present viewpoints that are more aligned with the alcohol industry than the scientific consensus on public health policy would warrant. The media are also expected, but to a lesser extent, to present a certain amount of support for public health perspectives because these are supported by a few socioeconomic elite groups (the medical professions, progressive politicians). The case of Ireland from 2012 to 2017 illustrates the framework empirically. Four main newspapers' coverage of the Public Health (Alcohol) Bill and related policies is examined. Results show that, overall, 44.0% of articles support public health measures and 56.0% are opposed or remain neutral. It is argued that the media are not strong proponents of public health for multiple reasons: there are more articles opposed to or neutral toward public health measures than supporting them; the number of supportive articles remains relatively small and there are still many pieces presenting drinks industry views; there are virtually no calls in the media for stronger measures; supportive coverage is partially explained by the pub owners lobby's support for minimum unit pricing; the media often downplay or ignore the negative consequences of alcohol, such as its role in accidents; many news articles normalise drinking and promote events sponsored by the industry; there is not a single Irish journalist covering alcohol issues systematically; and other policy issues that are prioritised by elites receive multiple times more media coverage than public health measures.

    The role of politics has often been discussed in evaluation theory and practice. The political influence of the situation can have major effects on the evaluation design, approach and methods. Politics also has the potential to influence the decisions made from the evaluation findings. The current study focuses on the influence of the political context on stakeholder decision making. Utilizing a simulation scenario, this study compares stakeholder decision making in high and low stakes evaluation contexts. Findings suggest that high stakes political environments are more likely than low stakes environments to lead to reduced reliance on technically appropriate measures and increased dependence on measures better reflect the broader political environment.

    The paper will inform the audience about the energy crisis that has crippled Pakistan's economic growth since the last 6 years, and the role that Bioenergy can play in resolving the issue. In order to help ease Pakistan in its effort to curb this crisis and to get useful insights into the role that Bioenergy can play in solving Pakistan's problems, Business planning for a Small or Medium sized enterprise was attempted. The results were not encouraging and shed light onto the financial and technical hindrances involved in creating and running Small or Medium bioenergy businesses in Pakistan. These issues themselves were linked to the more general Social, Economic and Political barriers for the adoption of Bioenergy in the country. The paper concludes by providing suggestions and recommendations, as to what the government, private sector as well as the international community can do in order to overcome the crisis.

    1998-10-01

    This study was initiated to find a method of determining the prognosis for possible changes in hemodynamic and respiratory parameters in patients with pneumoperitoneum (PP). We devised a model for a pseudopneumoperitoneum (PPP), which is created by encircling the wide pneumochamber on the entire abdomen and inflating it to a preset pressure. To verify the prognostic possibilities of the proposed model, we studied the pneumotachygraphy parameters, noninvasive and invasive monitoring parameters of PPP after induction of anaesthesia, and venous circulation disturbances, as well as the medical effect of the intermittent sequential compression device. In healthy patients, the restrictive lung syndrome did not approach the risky limit. In patients >/=60 years old, this syndrome was very close to the limit. In a number of patients with serious cardiovascular and pulmonary pathology, the pressure of >10 mmHg was considered to be intolerable. Lung compliance, which was the parameter most sensitive to the increased intraabdominal pressure, was 47 +/- 10 at baseline, and 29 +/- 4 (p > 0.05) at both PPP and real PP (14 mmHg). The PPP model is quite similar to the real PP and can be used for preoperative prognosis in laparoscopic surgery. The elevated intraabdominal pressure results in a significant disturbance of venous blood flow in the lower extremities. The use of the device for peristaltic pneumomassage of the lower limbs is effective in correcting negative changes in venous hemodynamics in laparoscopic surgery.

    The aim of this study was to evaluate the precision of bimaxillary surgery performed to correct vertical maxillary excess, when the procedure is sequenced with mandibular surgery first or maxillary surgery first. Thirty-two patients, divided into two groups, were included in this retrospective study. Group 1 comprised patients who received bimaxillary surgery following the classical sequence with repositioning of the maxilla first. Patients in group 2 received bimaxillary surgery, but the mandible was operated on first. The precision of the maxillomandibular repositioning was determined by comparison of the digital prediction and postoperative tracings superimposed on the cranial base. The data were tabulated and analyzed statistically. In this sample, both surgical sequences provided adequate clinical accuracy. The classical sequence, repositioning the maxilla first, resulted in greater accuracy for A-point and the upper incisor edge vertical position. Repositioning the mandible first allowed greater precision in the vertical position of pogonion. In conclusion, although both surgical sequences may be used, repositioning the mandible first will result in greater imprecision in relation to the predictive tracing than repositioning the maxilla first. The classical sequence resulted in greater accuracy in the vertical position of the maxilla, which is key for aesthetics.

    2007-01-01

    Previous studies in temporal lobe epilepsy (TLE) have shown that, owing to brain atrophy, positron emission tomography (PET) can overestimate deficits in measures of cerebral function such as glucose metabolism (CMR glu ) and neuroreceptor binding. The magnitude of this effect on cerebral blood flow (CBF) is unexplored. The aim of this study was to assess CBF deficits in TLE before and after magnetic resonance imaging-based partial volume correction (PVC). Absolute values of CBF for 21 TLE patients and nine controls were computed before and after PVC. In TLE patients, quantitative CMR glu measurements also were obtained. Before PVC, regional values of CBF were significantly (p glu in middle and inferior temporal cortex, fusiform gyrus and hippocampus both before and after PVC. A significant positive relationship between disease duration and AIs for CMR glu , but not CBF, was detected in hippocampus and amygdala, before but not after PVC. PVC should be used for PET CBF measurements in patients with TLE. Reduced blood flow, in contrast to glucose metabolism, is mainly due to structural changes. (orig.)

    Subject motion in positron emission tomography (PET) studies leads to image blurring and artifacts; simultaneously acquired magnetic resonance imaging (MRI) data provides a means for motion correction (MC) in integrated PET/MRI scanners. To assess the effect of realistic head motion and MR-based MC on static [ 18 F]-fluorodeoxyglucose (FDG) PET images in dementia patients. Observational study. Thirty dementia subjects were recruited. 3T hybrid PET/MR scanner where EPI-based and T 1 -weighted sequences were acquired simultaneously with the PET data. Head motion parameters estimated from high temporal resolution MR volumes were used for PET MC. The MR-based MC method was compared to PET frame-based MC methods in which motion parameters were estimated by coregistering 5-minute frames before and after accounting for the attenuation-emission mismatch. The relative changes in standardized uptake value ratios (SUVRs) between the PET volumes processed with the various MC methods, without MC, and the PET volumes with simulated motion were compared in relevant brain regions. The absolute value of the regional SUVR relative change was assessed with pairwise paired t-tests testing at the P = 0.05 level, comparing the values obtained through different MR-based MC processing methods as well as across different motion groups. The intraregion voxelwise variability of regional SUVRs obtained through different MR-based MC processing methods was also assessed with pairwise paired t-tests testing at the P = 0.05 level. MC had a greater impact on PET data quantification in subjects with larger amplitude motion (higher than 18% in the medial orbitofrontal cortex) and greater changes were generally observed for the MR-based MC method compared to the frame-based methods. Furthermore, a mean relative change of ∼4% was observed after MC even at the group level, suggesting the importance of routinely applying this correction.

    The second-wave feminist movement crystallized a new politics of personal identity that was fueled by and became inextricably linked to the modern university. On and off campus women organized into groups to press for political and educational rights. Along the way, women discovered that politics and education were both personal and that the achievement of "identity" offered the most direct path to true selfhood and liberation. This conclusion helped forge an enduring bond between higher education and identity group politics that continues to shape American higher education and politics to this day.

    1975-07-01

    Calculations of collision probability leakage estimates are performed in one dimensional slab geometry with one neutron group to gain some insight into methods of correction for the coarseness of the mesh H. The chief result is that the correction factor, beta, can be written as CD/H where C → 4 for the diffusion limit. An explicit expression for C is derived in terms of the E 3 function, for a linear flux variation across the slabs. (author)

Specific research questions were informed by the ‘theory of niche’ (Dimmick, 2003 which examines the coexistence and competition between different media outlets by examining the breadth, overlap and superiority of one platform over another. The survey was distributed using a ‘snowball’ technique between July and August 2015. The survey was shared by 52 student research assistants on their Facebook profiles. They asked their friends to complete the survey and share it with their own networks. Main results – The mean (M age of the 422 respondents was 23.5 years (SD=8.25. The majority were female (61% with a high school degree (89%. TV news and news websites were the most frequently used sources of political news. Facebook ranked third, ahead of newspapers, search engines, magazines, email provider websites, and Twitter. The mean score for the importance of Facebook as a news sources was 2.46 (SD=1.13 on a scale of 1 to 5, where 1 is low and 5 is high.

    This study investigates the portrayal of traditional political cultures in West Kalimantan Province, a growing of election process. Results showed that Political life in Indonesia leads to modern political culture after experiencing a change of paradigm of political life. Political life in Indonesia leads to modern political culture after experiencing a change of paradigm of political life. Beginning Indonesia’s independence in the Old Order Phase, the politics used using the ideological paradigm, subsequent to the New Order Period used the political paradigm of unification and simplification of political parties but in practice it became the strategy of the State’s rulers to facilitate subjugating its citizens. After entering the reform era, several phenomena of political culture are displayed, some are using modern paradigm by giving women the widest possible role in political parties, and so on. Besides that there is the opposite of displaying and practicing traditional political culture, this is as it runs in West Borneo Province. The change of political culture in the modern direction is different from the political culture of the citizens in terms of who will be chosen, most West Borneo Province residents determine their political choice by using traditional patterns.

    Full Text Available Background: Radiographic examination of TMJ is indicated when there are clinical signs of pathological conditions, mainly bone changes that may influence the diagnosis and treatment planning. The purpose of this study was to evaluate and to compare the validity and diagnostic accuracy of uncorrected and corrected sagittal tomographic images in the detection of simulated mandibular condyle erosions. Methods : Simulated lesions were created in 10 dry mandibles using a dental round bur. Using uncorrected and corrected sagittal tomography techniques, mandibular condyles were imaged by a Cranex Tome X-ray unit before and after creating the lesions. The uncorrected and corrected tomography images were examined by two independent observers for absence or presence of a lesion. The accuracy for detecting mandibular condyle lesions was expressed as sensitivity, specificity, and validity values. Differences between the two radiographic modalities were tested by Wilcoxon for paired data tests. Inter-observer agreement was determined by Cohen′s Kappa. Results: The sensitivity, specificity and validity were 45%, 85% and 30% in uncorrected sagittal tomographic images, respectively, and 70%, 92.5% and 60% in corrected sagittal tomographic images, respectively. There was a significant statistical difference between the accuracy of uncorrected and corrected sagittal tomography in detection of mandibular condyle erosions (P = 0.016. The inter-observer agreement was slight for uncorrected sagittal tomography and moderate for corrected sagittal tomography. Conclusion: The accuracy of corrected sagittal tomography is significantly higher than that of uncorrected sagittal tomography. Therefore, corrected sagittal tomography seems to be a better modality in detection of mandibular condyle erosions.

    In this paper, we have compared different bias correction methodologies to assess whether they could be advantageous for improving the performance of a seasonal prediction model for volume anomalies in the Boadella reservoir (northwestern Mediterranean). The bias correction adjustments have been applied on precipitation and temperature from the European Centre for Middle-range Weather Forecasting System 4 (S4). We have used three bias correction strategies: two linear (mean bias correction, BC, and linear regression, LR) and one non-linear (Model Output Statistics analogs, MOS-analog). The results have been compared with climatology and persistence. The volume-anomaly model is a previously computed Multiple Linear Regression that ingests precipitation, temperature and in-flow anomaly data to simulate monthly volume anomalies. The potential utility for end-users has been assessed using economic value curve areas. We have studied the S4 hindcast period 1981-2010 for each month of the year and up to seven months ahead considering an ensemble of 15 members. We have shown that the MOS-analog and LR bias corrections can improve the original S4. The application to volume anomalies points towards the possibility to introduce bias correction methods as a tool to improve water resource seasonal forecasts in an end-user context of climate services. Particularly, the MOS-analog approach gives generally better results than the other approaches in late autumn and early winter. Copyright © 2017 Elsevier B.V. All rights reserved.

    Leg edema is a common manifestation of various underlying pathologies. Reliable measurement tools are required to quantify edema and monitor therapeutic interventions. Aim of the present work was to investigate the reproducibility of optoelectronic leg volumetry over 3 weeks' time period and to eliminate daytime related within-individual variability. Optoelectronic leg volumetry was performed in 63 hairdressers (mean age 45 ± 16 years, 85.7% female) in standing position twice within a minute for each leg and repeated after 3 weeks. Both lower leg (legBD) and whole limb (limbBF) volumetry were analysed. Reproducibility was expressed as analytical and within-individual coefficients of variance (CVA, CVW), and as intra-class correlation coefficients (ICC). A total of 492 leg volume measurements were analysed. Both legBD and limbBF volumetry were highly reproducible with CVA of 0.5% and 0.7%, respectively. Within-individual reproducibility of legBD and limbBF volumetry over a three weeks' period was high (CVW 1.3% for both; ICC 0.99 for both). At both visits, the second measurement revealed a significantly higher volume compared to the first measurement with a mean increase of 7.3 ml ± 14.1 (0.33% ± 0.58%) for legBD and 30.1 ml ± 48.5 ml (0.52% ± 0.79%) for limbBF volume. A significant linear correlation between absolute and relative leg volume differences and the difference of exact day time of measurement between the two study visits was found (P correction formula permitted further improvement of CVW. Leg volume changes can be reliably assessed by optoelectronic leg volumetry at a single time point and over a 3 weeks' time period. However, volumetry results are biased by orthostatic and daytime-related volume changes. The bias for day-time related volume changes can be minimized by a time-correction formula.

    The prospect of high accuracy measurements investigating the weak interactions, which are expected to take place at the electron-positron storage ring LEP at CERN and the linear collider SCL at SLAC, offers the possibility to study also the weak quantum effects. In order to distinguish if the measured weak quantum effects lie within the margins set by the standard model and those bearing traces of new physics one had to go beyond the lowest order and also include electroweak radiative corrections (EWRC) in theoretical calculations. These higher-order corrections also can offer the possibility of getting information about two particles present in the Glashow-Salam-Weinberg model (GSW), but not discovered up till now, the top quark and the Higgs boson. In ch. 2 the GSW standard model of electroweak interactions is described. In ch. 3 some special techniques are described for determination of integrals which are responsible for numerical instabilities caused by large canceling terms encountered in the calculation of EWRC effects, and methods necessary to get hold of the extensive algebra typical for EWRC. In ch. 4 various aspects related to EWRC effects are discussed, in particular the dependence of the unknown model parameters which are the masses of the top quark and the Higgs boson. The processes which are discussed are production of heavy fermions from electron-positron annihilation and those of the fermionic decay of the Z gauge boson.

    The use of FORC diagrams is becoming increasingly popular among researchers devoted to magnetism and magnetic materials. However, a thorough interpretation of this kind of diagrams, in order to achieve quantitative information, requires an appropriate model of the studied system. For that reason most of the FORC studies are used for a qualitative analysis. In magnetic systems thermal fluctuations 'blur' the signatures of the anisotropy, volume and particle interactions distributions, therefore thermal effects in nanoparticles systems conspire against a proper interpretation and analysis of these diagrams. Motivated by this fact, we have quantitatively studied the degree of accuracy of the information extracted from FORC diagrams for the special case of single-domain thermal corrected Stoner– Wohlfarth (easy axes along the external field orientation) nanoparticles systems. In this work, the starting point is an analytical model that describes the behavior of a magnetic nanoparticles system as a function of field, anisotropy, temperature and measurement time. In order to study the quantitative degree of accuracy of our model, we built FORC diagrams for different archetypical cases of magnetic nanoparticles. Our results show that from the quantitative information obtained from the diagrams, under the hypotheses of the proposed model, is possible to recover the features of the original system with accuracy above 95%. This accuracy is improved at low temperatures and also it is possible to access to the anisotropy distribution directly from the FORC coercive field profile. Indeed, our simulations predict that the volume distribution plays a secondary role being the mean value and its deviation the only important parameters. Therefore it is possible to obtain an accurate result for the inversion and interaction fields despite the features of the volume distribution. - Highlights: • Quantify the degree of accuracy of the information obtained using the FORC diagrams.

    This article offers critical sociological and philosophical reflections on ayahuasca and other psychedelics as objects of research in medicine, health and human sciences. It situates 21st century scientific inquiry on ayahuasca in the broader context of how early modern European social trends and intellectual pursuits translated into new forms of empiricism and experimental philosophy, but later evolved into a form of dogmatism that convenienced the political suppression of academic inquiry into psychedelics. Applying ideas from the field of science and technology studies, we consider how ayahuasca's myriad ontological representations in the 21st century--for example, plant teacher, traditional medicine, religious sacrament, material commodity, cognitive tool, illicit drug--influence our understanding of it as an object of inquiry. We then explore epistemological issues related to ayahuasca studies, including how the indigenous and mestizo concept of "plant teacher" or the more instrumental notion of psychedelics as "cognitive tools" may impact understanding of knowledge. This leads to questions about whether scientists engaged in ayahuasca research should be expected to have personal experiences with the brew, and how these may be perceived to help or hinder the objectivity of their pursuits. We conclude with some brief reflections on the politics of psychedelic research and impediments to academic knowledge production in the field of psychedelic studies.

    The absorption and enhancement effects in X-ray fluorescence analysis for Ti, V and Fe elements were studied in the present paper. Three bogus duality systems of Ti-V/Ti-Fe/V-Fe samples were confected and measured by X-ray fluorescence analysis technique using HPGe semiconductor detector, and the relation curve between unitary coefficient (R(K)) of element count rate and element content (W(K)) were obtained after the experiment. Having analyzed the degree of absorption and enhancement effect between every two elements, the authors get the result, and that is the absorption and enhancement effect between Ti and V is relatively distinctness, while it's not so distinctness in Ti-Fe and V-Fe. After that, a mathematics correction method of exponential fitting was used to fit the R(K)-W(K) curve and get a function equation of X-ray fluorescence count rate and content. Three groups of Ti-V duality samples were used to test the fitting method and the relative errors of Ti and V were less than 0.2% as compared to the actual results.

    In a mouse intercross with more than 500 animals and genome-wide gene expression data on six tissues, we identified a high proportion (18%) of sample mix-ups in the genotype data. Local expression quantitative trait loci (eQTL; genetic loci influencing gene expression) with extremely large effect were used to form a classifier to predict an individual's eQTL genotype based on expression data alone. By considering multiple eQTL and their related transcripts, we identified numerous individuals whose predicted eQTL genotypes (based on their expression data) did not match their observed genotypes, and then went on to identify other individuals whose genotypes did match the predicted eQTL genotypes. The concordance of predictions across six tissues indicated that the problem was due to mix-ups in the genotypes (although we further identified a small number of sample mix-ups in each of the six panels of gene expression microarrays). Consideration of the plate positions of the DNA samples indicated a number of off-by-one and off-by-two errors, likely the result of pipetting errors. Such sample mix-ups can be a problem in any genetic study, but eQTL data allow us to identify, and even correct, such problems. Our methods have been implemented in an R package, R/lineup.

  9. Raman database of amino acids solutions: A critical study of Extended Multiplicative Signal Correction

    2013-01-01

    The Raman spectra of biological materials always exhibit complex profiles, constituting several peaks and/or bands which arise due to the large variety of biomolecules. The extraction of quantitative information from these spectra is not a trivial task. While qualitative information can be retrieved from the changes in peaks frequencies or from the appearance/disappearance of some peaks, quantitative analysis requires an examination of peak intensities. Unfortunately in biological samples it is not easy to identify a reference peak for normalizing intensities, and this makes it very difficult to study the peak intensities. In the last decades a more refined mathematical tool, the extended multiplicative signal correction (EMSC), has been proposed for treating infrared spectra, which is also capable of providing quantitative information. From the mathematical and physical point of view, EMSC can also be applied to Raman spectra, as recently proposed. In this work the reliability of the EMSC procedure is tested by application to a well defined biological system: the 20 standard amino acids and their combination in peptides. The first step is the collection of a Raman database of these 20 amino acids, and subsequently EMSC processing is applied to retrieve quantitative information from amino acids mixtures and peptides. A critical review of the results is presented, showing that EMSC has to be carefully handled for complex biological systems. © 2013 The Royal Society of Chemistry.

    Positron range limits the spatial resolution of PET images and has a different effect for different isotopes and positron propagation materials. Therefore it is important to consider it during image reconstruction, in order to obtain optimal image quality. Positron range distributions for most common isotopes used in PET in different materials were computed using the Monte Carlo simulations with PeneloPET. The range profiles were introduced into the 3D OSEM image reconstruction software FIRST and employed to blur the image either in the forward projection or in the forward and backward projection. The blurring introduced takes into account the different materials in which the positron propagates. Information on these materials may be obtained, for instance, from a segmentation of a CT image. The results of introducing positron blurring in both forward and backward projection operations was compared to using it only during forward projection. Further, the effect of different shapes of positron range profile in the quality of the reconstructed images with positron range correction was studied. For high positron energy isotopes, the reconstructed images show significant improvement in spatial resolution when positron range is taken into account during reconstruction, compared to reconstructions without positron range modeling.

  12. European Union: Gender and politics

    Full Text Available Political representation is the central issue in contemporary debates on the level of democracy in political institutions and processes in the European Union. Underrepresentation of particular groups in political institutions, decision-making and policy-making processes is perceived as the problem of justice, legitimacy and effectiveness in democratic societies. In this paper, the author analyzes the gender aspects of democratic decision-making processes and political representation of women in the EU member states. The social, historical and political dimension of women's efforts to obtain and promote their civil status and political rights have been the framework for developing the principle of gender equality as one of the founding EU principles. In the past hundred years, one of the most significant trends in politics has been the expansion of formal political representation of women. Yet, even though it has been more than a hundered years since women won their political rights in the 19th and the 20th century (the right to vote and the right to be voted, gender differences in political rights are still a substantial part of debate. Today, women's political representation is still inadequate and their political capacity and power have not been exercised to a sufficient extent (or proportionally through their actual representation in parliament. In March 2012, the European Commisision published a report on gender equality in different areas of social life; the Eurobarometer survey shows that women are generally underrepresented in politics. In national parliaments, only one out of four MPs is a woman. In the European Parliament, three out of ten parliamentarians are women. The statistics shows a huge discrepancy among the EU Member States in terms of women's representation in parliament (44.7% in Sweden as contrasted to 13.3% in Romania. The prevailing view in many studies is that post-industrial democracies are deficient as they have failed

    Eliana Valeria Fucili

    2018-01-01

    Full Text Available This paper provides some theses to enrich studies on the conformation and characterization of nineteenth century Argentinean ruling groups. For this purpose, the article takes as its object of study the political teams of the Mendoza province that emerged during the second half of the 19th century, and presents solid empirical evidence to identify a set of 725 political actors responsible of embodying and activating the dynamics of the provincial state. This information has been analyzed with quantitative methods and qualitative tools such as prosopography, sociological interpretations and sociability analyses, allowing us to distinguish several features of the local leadership. A wide variety of documents—official records, departmental dispatches, press of the time— was used to investigate these questions, in order to explore the variables related to the unfolding of these actors’ political careers: their socio-professional profile, their continuity or permanence in public service positions, and the projection of their itineraries. As a whole, the article constitutes a contribution to current historiographical debates about the relative complexity of the nineteenth century political system and the role of provincial and local political groups in the process of shaping the Argentine national state. This study also represents a substantive advance in regard to literature about elites and ruling teams, which has been based on meager and unsystematic data, producing hasty generalizations that have nevertheless been taken as valid indicators to define a broad political spectrum.

    2017-05-01

    Full Text Available Galvanic distortions of magnetotelluric (MT data, such as the static-shift effect, are a known problem that can lead to incorrect estimation of resistivities and erroneous modelling of geometries with resulting misinterpretation of subsurface electrical resistivity structure. A wide variety of approaches have been proposed to account for these galvanic distortions, some depending on the target area, with varying degrees of success. The natural laboratory for our study is a hydraulically permeable volume of conductive sediment at depth, the internal resistivity structure of which can be used to estimate reservoir viability for geothermal purposes; however, static-shift correction is required in order to ensure robust and precise modelling accuracy.We present here a possible method to employ frequency–domain electromagnetic data in order to correct static-shift effects, illustrated by a case study from Northern Ireland. In our survey area, airborne frequency domain electromagnetic (FDEM data are regionally available with high spatial density. The spatial distributions of the derived static-shift corrections are analysed and applied to the uncorrected MT data prior to inversion. Two comparative inversion models are derived, one with and one without static-shift corrections, with instructive results. As expected from the one-dimensional analogy of static-shift correction, at shallow model depths, where the structure is controlled by a single local MT site, the correction of static-shift effects leads to vertical scaling of resistivity–thickness products in the model, with the corrected model showing improved correlation to existing borehole wireline resistivity data. In turn, as these vertical scalings are effectively independent of adjacent sites, lateral resistivity distributions are also affected, with up to half a decade of resistivity variation between the models estimated at depths down to 2000 m.

  17. Competition among states: Case studies in the political role of remote sensing capabilities

    Science.gov (United States)

    Ammons, Audrey Ann

    International politics is a competitive realm. One of the most powerful modern advantages in this competitive world is the ownership of independent and autonomous remote sensing satellites. Few have this venue for competition and those that do belong to a very exclusive groups of states. Kenneth Waltz, author of Theory of International Politics, theorized that states emulate the innovations, strategies and practices of those countries with the greatest capability and ingenuity. As Waltz explains, states will emulate the leader in an anarchic realm to attain the same capabilities that helped the hegemon attain or maintain its status. Waltz referred to this as a tendency toward sameness of the competitors. Modern-day states that pursue global preeminence often exhibit exceptional risk-taking and significant technological innovation. They also challenge the recognized hegemon in an area of expertise and leadership. Realists would say that these states are emulating the behavior of the states they view as successful in order to maintain or improve their position in the world order. Realists also point out that strategic interests lead states to try to gain or at least neutralize those areas that, if controlled by an adversary, could menace them. Realist writers suggest that states will be reluctant to cede control of an important new technology to another state, even a friendly one, lest they find themselves permanently disadvantaged in an on-going contest for wealth, influence and even preeminence. The purpose of this research is to investigate if remote sensing capabilities are a venue of competition among modern states and one that they view as a potential path to global preeminence. Why do some states expend scarce resources to develop and maintain an indigenous remote sensing capability when it appears that they can acquire much of the end product from other sources at a reasonable cost? If this is true, it should be possible to confirm that states acquire end

    2012-01-01

    This paper argues that the South Korean scholarship on modem Chinese history since 1945 can be characterized as apolitical with its objectivism,positivism,liberalism,and anti-communist nationalism.This characteristic is a product of not only the Cold War and the military regimes of South Korea but also the political orientation and stance of the senior historians who played an initial and decisive role in determining the goal,direc tion,and research methods of South Korean studies concerning modem China.The SouthKorean perspective they promoted usually meant the study of liberal,apolitical topics in Chinese history from a nationalist perspective without any political/ideological influences.The utility of modern Chinese history has mainly lain in helping to construct an anti-socialist,modern Korean nation-state through modernization.South Korean historians of modem China,the paper argues,have not been able to induce a meaningful,broad discussion of critical historical issues in modem China as they might pertain to South Korean society,thus failing to utilize them to help challenge and transform the undemocratic South Korean society and regimes.Hence,the future success of new academic undertakings since the 1990s by South Korean historians will be determined by whether or not they are able to make a radical break from the previous scholarship,in particular,from its objectivism and nationalism.

  19. Present status and future prospects of spherical aberration corrected TEM/STEM for study of nanomaterials

    International Nuclear Information System (INIS)

    Tanaka, Nobuo

    2008-01-01

    The present status of Cs-corrected TEM/STEM is described from the viewpoint of the observation of nanomaterials. Characteristic features in TEM and STEM are explained using the experimental data obtained by our group and other research groups. Cs correction up to the 3rd-order aberration of an objective lens has already been established and research interest is focused on correcting the 5th-order spherical aberration and the chromatic aberration in combination with the development of a monochromator below an electron gun for smaller point-to-point resolution in optics. Another fundamental area of interest is the limitation of TEM and STEM resolution from the viewpoint of the scattering of electrons in crystals. The minimum size of the exit-wave function below samples undergoing TEM imaging is determined from the calculation of scattering around related atomic columns in the crystals. STEM does not have this limitation because the resolution is, in principle, determined by the probe size. One of the future prospects of Cs-corrected TEM/STEM is the possibility of extending the space around the sample holder by correcting the chromatic and spherical aberrations. This wider space will contribute to the ease of performing in situ experiments and various combinations of TEM and other analysis methods. High-resolution, in situ dynamic and 3D observations/analysis are the most important keywords in the next decade of high-resolution electron microscopy. (topical review)

    Twenty-eight states have laws and regulations limiting the ability of nurse practitioners (NPs) to practice to the full extent of their education and training, thereby preventing patients from fully accessing NP services. Revisions to state laws and regulations require NPs to engage in the political process. Understanding the political engagement of NPs may facilitate the efforts of nurse leaders and nursing organizations to promote change in state rules and regulations. The purpose of this study was to describe the political efficacy and political participation of U.S. NPs and gain insight into factors associated with political interest and engagement. In the fall of 2015, we mailed a survey to 2,020 NPs randomly chosen from the American Academy of Nurse Practitioners' database and 632 responded (31% response rate). Participants completed the Trust in Government (external political efficacy) and the Political Efficacy (internal political efficacy) scales, and a demographic form. Overall, NPs have low political efficacy. Older age ( p≤.001), health policy mentoring ( p≤.001), and specific education on health policy ( p≤.001) were all positively associated with internal political efficacy and political participation. External political efficacy was not significantly associated with any of the study variables. Political activities of NPs are largely limited to voting and contacting legislators. Identifying factors that engage NPs in grassroots political activities and the broader political arena is warranted, particularly with current initiatives to make changes to state laws and regulations that limit their practice.

    The chapter engages in a survey of what political psychology and European integration have to say to each other in the understanding of the European Union. The chapter draws on five strands of political psychology as part of this engagement – conventional psychology, social psychology, social...... construction, psychoanalysis, and critical political psychology. Within each strand a number of examples of scholarship at the interface of political psychology and European integration are examined. The chapter argues that the study of the EU has much to benefit from political psychology in terms of theories...... and methods of European identity and integration, but it also argues that political psychology can benefit from the insights of European integration by rethinking the processes that drive the marking of inside and outside, interior and exterior, belonging and otherness....

    To assess the effectiveness of an intervention to promote standardized arm circumference measurement as way to choose appropriate cuff size to measure blood pressure. A before-after intervention study was performed in a basic health care area in Barcelona. Doctors, nurses and pharmacy staff participated by filling out an anonymous self-administered questionnaire pre- and post-intervention (3m). Variables included: demographics, type of professional, years since they finished their studies, availability of different cuff sizes, if arm circumference measurement were obtained or not, knowledge about the cutoff values for each cuff size and type of blood pressure monitor. The written results were given to the participants and presented in sessions. Pre- and post-intervention: 74.3 and 67.3% answered the questionnaires (P=ns), respectively. Determination of arm circumference varied from 1.3 to 19.1% (P=.009). A total of 37.3% and 44.1% declared that they had 2 or more available cuff sizes (P=ns). Knowledge about the correct measurement of the cuffs was 2.7 to 33.8% regarding the standard cuff size (P=.0198) and 0 to 23.5% for obese subjects (P<.05). When more than one cuff was available, reasons for the choice went from: «making a rough guess» or «when velcro stops sticking» before and after the intervention. All blood pressure devices in our primary health care center were electronic and automatic as were those of the 9 pharmacies. The intervention increased the determination of arm circumference prior to the reading of the blood pressure and the knowledge about the cutoff interval for standard and obese cuff size after intervention. There was greater availability of different sized cuffs. Despite this, the choice of the appropriate cuff size was not made based on arm circumference. Copyright © 2014 SEHLELHA.

    Previous studies in temporal lobe epilepsy (TLE) have shown that, owing to brain atrophy, positron emission tomography (PET) can overestimate deficits in measures of cerebral function such as glucose metabolism (CMR{sub glu}) and neuroreceptor binding. The magnitude of this effect on cerebral blood flow (CBF) is unexplored. The aim of this study was to assess CBF deficits in TLE before and after magnetic resonance imaging-based partial volume correction (PVC). Absolute values of CBF for 21 TLE patients and nine controls were computed before and after PVC. In TLE patients, quantitative CMR{sub glu} measurements also were obtained. Before PVC, regional values of CBF were significantly (p<0.05) lower in TLE patients than in controls in all regions, except the fusiform gyrus contralateral to the epileptic focus. After PVC, statistical significance was maintained in only four regions: ipsilateral inferior temporal cortex, bilateral insula and contralateral amygdala. There was no significant difference between patients and controls in CBF asymmetry indices (AIs) in any region before or after PVC. In TLE patients, AIs for CBF were significantly smaller than for CMR{sub glu} in middle and inferior temporal cortex, fusiform gyrus and hippocampus both before and after PVC. A significant positive relationship between disease duration and AIs for CMR{sub glu}, but not CBF, was detected in hippocampus and amygdala, before but not after PVC. PVC should be used for PET CBF measurements in patients with TLE. Reduced blood flow, in contrast to glucose metabolism, is mainly due to structural changes. (orig.)

    Full Text Available Based on Lakoff’s (2002 Strict Father and Nurturant Parent metaphors for political conservatism and liberalism respectively, two studies explored parenting styles, political ideology, and the moral orientations that might link the two. Restrictive parenting (by both mother and father predicted political conservatism, and this path was mediated by a strong Social Order orientation (Study 1 reflecting, more broadly, an inhibition-based proscriptive morality (Study 2. Political liberalism was associated with a Social Justice orientation, but was not predicted by nurturant parenting in either study. Study 1 included mothers’ reports of their own parenting, and these were correlated with the students’ responses. Findings support a restrictive moral underpinning for conservatism, but raise questions about the assumed unique association between parental nurturance and political liberalism, which is addressed in the discussion.

    Price, Terence.

    1990-01-01

    This book is a non-technical exploration of the political and policy issues that have influenced the development of nuclear power. Part One describes the successes, failures, horse-trading, and infighting that make up nuclear power's history, taking nine counties as examples. Part Two reviews the main problems that now confront us, as seen in mid-June 1990; like all contemporary accounts, the book is unavoidably incomplete. However, by then it was possible to make provisional judgements about two very important recent influences: the political consequences of Chernobyl, and concerns about the greenhouse effect. The story that emerges is of a nuclear industry that has rarely been guilty of dereliction of duty, though it was undeniably complacent in not addressing sooner the causes of the public's entirely reasonable anxieties. The anti-nuclear lobby has been skilled in debate, and sometimes extraordinarily percipient; but less than fair in failing to acknowledge the industry's achievements and its willingness to learn from past mistakes. As for the politicians, the book contains many examples that show how the flames of controversy can be deliberately fanned when there are votes to be gained. The story has few heroes, but within the industry fewer villains than the public has been led to believe. (author)

    Full Text Available I write from Prague, where, unlike in most urban formations, the main city street plays an iconic role; it references a history of political protest. However, before elaborating on the protest iconography of the Prague street, Vaclavske nam, I want to locate the ways in which the design of urban space is actualized in everyday life in the cities of the world. Three functions stand out; the first involves dwelling, the second seeing, and the third moving. With respect to the first function – dwelling – the design partitions and coordinates residential, commercial and leisure functions. At times these are organized to segregate different classes (Robert Moses’ redesign of much of New York stands out with respect to the segregation function. With respect to the second function – seeing – the design of urban space is allegiance-inspiring; it involves sight lines that afford urban dwellers and visitors views of iconic buildings and statues, which reference key founding moments in the past and/or authoritative political functions in the present (Here, L’Enfants design for Washington DC stands out as exemplary. Its manifest intention was to make the buildings housing executive, legislative and judicial functions visible from many vantage points. Rarely are the streets themselves iconic. Their dominant role is involved with the effectuation of movement. As for this third function: As Lewis Mumford famously points out, streets were once part of an asterisk design, radiating out from an exemplary, often spiritual center...

    The logarithmic amplification of video signals and the availability of data in digital form make digital subtraction videoangiography a suitable tool for videodensitometric estimation of physiological quantities. A system for this purpose was implemented with a digital video image processor. However, it was found that the radiation scattering and veiling glare present in the image-intensified video must be removed to make meaningful quantitations. An algorithm to make such a correction was developed and is presented. With this correction, the videodensitometry system was calibrated with phantoms and used to measure the left ventricular ejection fraction of a canine heart

    The aim of this study was to search for an effect of the adverse economic and political events that took place in 2015 in Greece (threat of bankruptcy, referendum, capital controls) on depressive symptoms of breast cancer patients on chemotherapy. The clinician-rated version of the Inventory of Depressive Symptomatology (IDS-C30) and a form documenting sociodemographic, medical and social network characteristics were administrated in two groups of patients: one in 2010 and one in the aftermath of the July 2015 events. No differences were found between medical, demographic and social characteristics. The IDS-C30 median value of patients treated in 2010 was 28.07 (CI, 25.91-31.60), while that of the 2015's group was 18.00 (CI, 16.92-20.60), indicating less depressive symptoms for the second group. The analysis revealed that the differences between the two groups were statistically significant (p = <.001), denoting a strong effect size (r = .53). Lower depressive symptoms after the July 2015 events could be explained by different personal and social factors- most possibly an increase of social support to the most vulnerable-yet to be proven. Future research on the effect of striking economic and political events on mental health of a larger cohort of breast cancer patients is warranted. © 2017 John Wiley & Sons Ltd.

    Despite the high prevalence rate of mental health problems among young prisoners, little is known about the longitudinal course and covariates of their mental health symptoms during incarceration, especially the influence of the correctional climate. The current study aimed: (1) to examine changes in young prisoners' mental health symptoms during incarceration, (2) to identify personal factors associated with their mental health symptoms and perceptions of the correctional climate, and (3) to test the incremental effect of perceptions of the correctional climate on mental health symptoms. Data were obtained from a sample of 75 youths (aged 17 to 22 years) detained in a Portuguese young offender prison. Data were gathered 1, 3, and 6 months after their admission in this facility. Socio-demographic, clinical and criminological variables were collected. Mental health symptoms and perceptions of the correctional climate were assessed through self-report assessment tools. Linear and logistic (multi-level) regressions and tests for differences between means were performed to analyze the data. Overall, mental health symptoms marginally declined by the sixth month in prison. Prisoners with a history of mental health treatment were more likely to have increased symptoms. Higher levels of mental health symptoms were associated with a history of mental health treatment, remand status, and a lower educational level. Better perceptions of the correctional climate were associated with Black race and participation in prison activities. A negative perception of the correctional climate was the strongest covariate of young prisoners' mental health symptoms and had incremental validity over that of personal variables. The results highlight that both characteristics of the prisoners and of the prison environment influence young prisoners' mental health. Prison management can try to reduce young prisoners' mental health problems by developing scientific procedures for their mental

    To understand the underlying physics behind the interaction of biomolecules with the nanomaterials to use them practically as bio-nanomaterials is very crucial. A first principles calculation under the frame work of density functional theory is executed to investigate the electronic structures and binding properties of alkaloids (Caffeine and Nicotine) over single walled boron nitride nanotube (BNNT) and boron nitride nanoribbon (BNNR) to determine their suitability towards filtration or sensing of these molecules. We have also used GGA-PBE scheme with the inclusion of Van der Waals (vdW) interaction based on DFT-D2. Increase in the accuracy by incorporating the dispersion correction in the calculation is observed for the long range Van der Waals interaction. Binding energy range of BNNT and BNNR with both alkaloids have been found to be -0.35 to -0.76 eV and -0.45 to -0.91 eV respectively which together with the binding distance shows physisorption binding of these molecules to the both nanostructures. The transfer of charge between the BN nanostructures and the adsorbed molecule has also been analysed by using Lowdin charge analysis. The sensitivity of both nanostructures BNNT and BNNR towards both alkaloids is observed through electronic structure calculations, density of states and quantum conductance. The binding of both alkaloids with BNNR is stronger. The analysis of the calculated properties suggests absence of covalent interaction between the considered species (BNNT/BNNR) and alkaloids. The study may be useful in designing the boron nitride nanostructure based sensing device for alkaloids.

  13. Destructiveness in Political Discourse

    2016-12-01

    Full Text Available Destructiveness is among the fundamental discourse categories that play a significant role in the organization of communicative interaction and define the pragmatics of discourse; its study helps to understand some mechanisms and principles of communication, identify strategies and tactics used by a destructive communicative personality. The relevance of this study is determined by the increasing aggressiveness in various types of discourse, and, accordingly, by the need to extend the knowledge of destructive behavior of a communicative personality. The study is based on the theory of discourse-analysis and theory of destructiveness (Z. Harris, T. van Dijk, A. Buss, E. Fromm, D. Ponton, K. Hacker, R. Wodak. N. Arutyunova, V. Karasik, M. Makarov, E. Sheigal et al. Developing the theory of destructiveness and relying on Erich Fromm’s research (1973, we specify the concept of “destructiveness” in relation to the political discourse and compare it with the related concept of aggressiveness. The paper analyses the category of destructiveness in modern US political discourse, using excerpts from the speeches of the candidates for presidency of 2016. Particular attention is paid to the dominant destructive intention - to harm the reputation of the opponent and reduce his political chances, as well as to the functions of verbal aggression: on the one hand - to discredit the opponent, bring accusations, on the other hand - to poison the audience mind against him/her and arouse the feeling of danger posed by a political opponent. The analysis of verbal and nonverbal means of destructiveness in the US political discourse is carried out. The article concludes that abusive remarks of politicians do not result from spontaneous emotional outburst, but from an elaborated destructive strategy where the agonistic nature of political discourse stipulates the use of instrumental aggression (Buss, 1971 for the sake of the conquest of power, lowering the

    Directory of Open Access Journals (Sweden)

    Benjamin Gross

    2013-02-01

    Full Text Available During the 2000 Presidential election between George H. W. Bush and Al Gore, journalists often used the terms blue states and red states to describe the political landscape within the United States. This article studies the framing of these terms during the years 2004 through 2007. Using latent and manifest qualitative content analyses, six different news media frames were found in a sample of 337 newspaper articles. Two hypotheses were also tested indicating that framing patterns varied slightly by time period and article types. However, the argument that increased levels of political polarization in the United States have been created by predominantly conflict-oriented coverage may not be true. Instead, these terms became journalistic heuristics that were used to organize how people think about politics in a way that fit with contemporary media practices, and there is no single agreed upon interpretation of these terms within this reporting.

    Objective: To explore the image correction of fracture displacement by conventional X-ray photography (ortho tropic and lateral) and test by computed tomography (CT). Methods: The correction method of fracture displacement was designed according to geometry of X-ray photography. Selected one midhumeral fracture specimen which designed with lateral shift and angular displacement, and scanned from anteroposterior and position respectively, and also volume scanned using CT, the data obtained from volume scan were processed using multiplanar reconstruction (MPR) and shaded surface display (SSD). The displacement data relied on X-ray image, CT with MPR and SSD processing, actual design of specimens were compared respectively. Results: The direction and degree of displacement among correction data of X-ray images and the data from MPR and SSD, actual design of specimen were little difference, location difference <1.5 mm, degree difference <1.5 degree. Conclusion: It is really reliable for fracture displacement by conventional X-ray photography with coordinate correction, and it is helpful to obviously improve the diagnostic accuracy of the degree of fracture displacement.

    Peak ratio correction factors for accurate quantitative determination of copper by NAA via 64 Cu radioisotope in presence of high 24 Na radioactivities has been established. Copper is the principal element as a marker of bullet residues on targets in connection to forensic ballistics cases. Reliable and precise estimation of copper by NAA either via non-destructive way or by resorting to radiochemical separation is of importance in forensic analysis for arriving at definitive inferences. However, majority of samples originating from wearing apparels, paper, leather, skin, glass or any other metal exhibit matrices contain high levels of sodium. The NAA scheme for determination of copper rests on measurements of net counts at 511 KeV which is the positron annihilation peak of 64 Cu. 24 Na also contributes significantly exactly at 511 KeV of gamma energy albeit by different mechanism i.e., by pair production. Therefore, total signal at 511 KeV is contributed by both. The easiest approach for correct estimation of copper traces has been established by the peak ratio correction factor. This has significance as both 64 Cu and 24 Na have comparable half lives, hence, as such time gap measurements cannot improve the situation. The consistency of peak ratio correction factor could be established for a particular geometry. (author)

  1. A study on improving international political and diplomatic acceptability of advanced nuclear fuel cycle for Korea

    International Nuclear Information System (INIS)

    Lee, Joeng Hoon

    2011-03-01

    In order to establish an advanced nuclear fuel cycle program for Korea, U.S. support and trust are imperative. In the midst of the negotiations for the renewal of the U.S.-South Korea agreement on peaceful nuclear cooperation, the two obvious components of an advanced nuclear fuel cycle - enrichment and reprocessing - have surfaced as major issues. Despite the United States' firm commitment to nonproliferation, South Korea is in dire need to advance its nuclear fuel cycle proportionate to its now significant nuclear energy program. This research project's objective is to put the U.S.-South Korea Nuclear Agreement into proper alliance perspective. The military alliance between the two countries have weathered decades of trials and tribulations. It is one of the most staunch alliances in existence in global politics. As such, the negotiations for the nuclear agreement must be dealt with in the context of the broader alliance relations, not to be lost in the technicalities of the nonproliferation arguments. But even so, South Korea's track record is far better than some of the states the United States has recently granted a most lenient nuclear agreement - India being a case in point. Fairness issue also surfaces when it comes to the agreement the United States has concluded with Japan. As an equally if not more important ally in Asia, South Korea must be permitted to make significant advancements in either enrichment or reprocessing procedures. This project argues that this is the appropriate direction given the history of the two nations' alliance relations. In the final analysis, this research puts forward the argument that the matter that should count the most is not the question of whether South Korea will proliferate or not, but rather whether the United States trusts its battle-tested ally, enough to help develop a peaceful and efficient advanced nuclear fuel cycle program in South Korea

    2015-08-15

    Purpose: To demonstrate the feasibility of proton dose calculation on scatter-corrected cone-beam computed tomographic (CBCT) images for the purpose of adaptive proton therapy. Methods: CBCT projection images were acquired from anthropomorphic phantoms and a prostate patient using an on-board imaging system of an Elekta infinity linear accelerator. Two previously introduced techniques were used to correct the scattered x-rays in the raw projection images: uniform scatter correction (CBCT{sub us}) and a priori CT-based scatter correction (CBCT{sub ap}). CBCT images were reconstructed using a standard FDK algorithm and GPU-based reconstruction toolkit. Soft tissue ROI-based HU shifting was used to improve HU accuracy of the uncorrected CBCT images and CBCT{sub us}, while no HU change was applied to the CBCT{sub ap}. The degree of equivalence of the corrected CBCT images with respect to the reference CT image (CT{sub ref}) was evaluated by using angular profiles of water equivalent path length (WEPL) and passively scattered proton treatment plans. The CBCT{sub ap} was further evaluated in more realistic scenarios such as rectal filling and weight loss to assess the effect of mismatched prior information on the corrected images. Results: The uncorrected CBCT and CBCT{sub us} images demonstrated substantial WEPL discrepancies (7.3 ± 5.3 mm and 11.1 ± 6.6 mm, respectively) with respect to the CT{sub ref}, while the CBCT{sub ap} images showed substantially reduced WEPL errors (2.4 ± 2.0 mm). Similarly, the CBCT{sub ap}-based treatment plans demonstrated a high pass rate (96.0% ± 2.5% in 2 mm/2% criteria) in a 3D gamma analysis. Conclusions: A priori CT-based scatter correction technique was shown to be promising for adaptive proton therapy, as it achieved equivalent proton dose distributions and water equivalent path lengths compared to those of a reference CT in a selection of anthropomorphic phantoms.

  5. The politics of harm reduction in federal prisons.

    Science.gov (United States)

    Watson, Tara Marie

    2014-09-01

    We need to understand better the political barriers to prison-based harm reduction programs. In this paper, I examine the situation in the Correctional Service of Canada (CSC), a federal prison agency with a zero-tolerance drug policy and general opposition to prison needle and syringe programs (PNSPs) and safer tattooing initiatives. This study draws on 16 interviews with former CSC senior officials, former frontline staff, and external stakeholders; CSC policy and practice documents; and testimony from a House of Commons Standing Committee public study. Thematic coding and comparison of texts were used to examine emergent themes of interest. Four interrelated issues were central for understanding the political barriers: a narrower definition of harm reduction used in corrections, both in principle and practice; the Conservative government's tough-on-crime agenda; strong union opposition; and stakeholder perceptions that political constraints will likely persist, including the view that litigation may offer the only way to introduce PNSPs. The system is at an impasse and key questions remain about the importability of harm reduction services into federal prisons. Despite a highly challenging policy environment, moving forward will demand asking new, critical questions and devising more strategic ways of entering the political-operational dialogue that opposes evidence-based programs.

    Theories suggest that political ideology relates to cooperation, with conservatives being more likely to pursue selfish outcomes, and liberals more likely to pursue egalitarian outcomes. In study 1, we examine how political ideology and political party affiliation (Republican vs. Democrat) predict cooperation with a partner who self-identifies as Republican or Democrat in two samples before (n = 362) and after (n = 366) the 2012 US presidential election. Liberals show slightly more concern for their partners’ outcomes compared to conservatives (study 1), and in study 2 this relation is supported by a meta-analysis (r = .15). However, in study 1, political ideology did not relate to cooperation in general. Both Republicans and Democrats extend more cooperation to their in-group relative to the out-group, and this is explained by expectations of cooperation from in-group versus out-group members. We discuss the relation between political ideology and cooperation within and between groups. PMID:29593363

  9. Aesthetics and Political Culture in Modern Society

    Nielsen, Henrik Kaare

    Do aesthetic appeals to senses and emotions in political debate necessarily marginalise political reason and reduce citizens to consumers – thus dangerously undermining democracy? Or is sensuous-emotional engagement, on the contrary, a basic fact of the political process and a crucial precondition...... in the political process do not by definition undermine politics’ content of reason. Instead, a differentiation must be made between a multiplicity of aesthetic forms of intervention – some of which tend to weaken the political judgement of citizens while other forms tend to stimulate competent judgement.......

    Full Text Available AIM: To study the ortho-k lens and frame glasses in patients with juvenile myopia the influence of the accommodative convergence/accommodation(AC/A, further clear the effectiveness of controlling the myopia development and security.METHODS: Randomly select 60 patients to our hospital check-up successfully with ortho-k lens of juvenile myopia patients as experimental group, and 60 cases were randomly selected given frame glasses as control group. we observed two groups of patients before and after refractive correction the changes of AC/A and spherical equivalent. Observation time was 1 month, 3 months, 6 months, 1 year.RESULTS: The AC/A of experimental group worn glasses before and after 1 month, 3 months, 6 months, 1 year were 4.05±2.03, 3.05±1.85, 3.31±1.02, 3.14±1.64 and 3.20±1.55,respectively with statistically significant difference(PP>0.05. Three months after worn glasses there was significant difference(PP>0.05. Wearing glasses after 1 month, 6 months, 12 months, the two groups had significant difference(PP>0.05. Spherical equivalent, observation time was 1 year: experimental group spherical equivalent degrees increased by 0.38±0.35DS, the control group spherical equivalent degrees increased by 0.84±0.56DS, the two groups were statistically significant difference(PCONCLUSION: Both groups could reduce the AC/A value. The experimental group than the control group was better and faster to improve the relationship between the adjustment and collection. The AC/A value was on the high side after myopic degree growth. The ortho-k lens is an effective lens for the moderate myopia.It can more effectively control the growth of juvenile myopia than frame glasses, which is an effective way to control myopia. The mechanism of improving his visual function remains to be further studied.

    Statistical image analysis of brain SPECT images has improved diagnostic accuracy for brain disorders. However, the results of statistical analysis vary depending on the institution even when they use a common normal database (NDB), due to different intrinsic spatial resolutions or correction methods. The present study aimed to evaluate the correction of spatial resolution differences between equipment and examine the differences in skull bone attenuation to construct a common NDB for use in multicenter settings. The proposed acquisition and processing protocols were those routinely used at each participating center with additional triple energy window (TEW) scatter correction (SC) and computed tomography (CT) based attenuation correction (CTAC). A multicenter phantom study was conducted on six imaging systems in five centers, with either single photon emission computed tomography (SPECT) or SPECT/CT, and two brain phantoms. The gray/white matter I-123 activity ratio in the brain phantoms was 4, and they were enclosed in either an artificial adult male skull, 1300 Hounsfield units (HU), a female skull, 850 HU, or an acrylic cover. The cut-off frequency of the Butterworth filters was adjusted so that the spatial resolution was unified to a 17.9 mm full width at half maximum (FWHM), that of the lowest resolution system. The gray-to-white matter count ratios were measured from SPECT images and compared with the actual activity ratio. In addition, mean, standard deviation and coefficient of variation images were calculated after normalization and anatomical standardization to evaluate the variability of the NDB. The gray-to-white matter count ratio error without SC and attenuation correction (AC) was significantly larger for higher bone densities (p correction. The proposed protocol showed potential for constructing an appropriate common NDB from SPECT images with SC, AC and spatial resolution compensation.

    The interaction between political executives and civil servants rests on a delicate balance between political responsiveness and the duty of civil servants and ministers to respect legal and other normative constraints on executive authority. In Danish central government, this balance is stressed...... by norms that define the correct behavior when the civil service provides ministers with political advice and assistance. Organizational factors strongly influence civil servants’ behavior when they have to balance responsiveness against constraints on their role as political advisers. Moreover, civil...

    The external security threat is known as the most important factor of nuclear weapons program, the domestic politics situation can also affect the nuclear proliferation decision of a country. For example, when a leader wants nuclear weapons as an ultimate weapon, the domestic politics situation can determine the effectiveness of the weapons program of a country. This study analyzes the current knowledge of the relationship between domestic politics and nuclear proliferation and suggests the main challenges of the quantitative models trying to calculate nuclear proliferation risk of countries. The domestic politics status is one of the most important indicators of nuclear program. However, some variables have never been used in quantitative analyses; for example, number of veto players and the public opinion on nuclear weapons; despite they are considered to be important in various qualitative studies. Future studies should focus on how should they be coded and how can they be linked with existing domestic politics variables

    Purpose: Target localization accuracy of cone-beam CT (CBCT) images used in radiation treatment of respiratory disease sites is affected by motion artifacts (blurring and streaking). The authors have previously reported on a method of respiratory motion correction in thoracic CBCT at end expiration (EE). The previous retrospective study was limited to examination of reducing motion artifacts in a small number of patient cases. They report here on a prospective study in a larger group of lung cancer patients to evaluate respiratory motion-corrected (RMC)-CBCT ability to improve lung tumor localization accuracy and reduce motion artifacts in Linac-mounted CBCT images. A second study goal examines whether the motion correction derived from a respiration-correlated CT (RCCT) at simulation yields similar tumor localization accuracy at treatment. Methods: In an IRB-approved study, 19 lung cancer patients (22 tumors) received a RCCT at simulation, and on one treatment day received a RCCT, a respiratory-gated CBCT at end expiration, and a 1-min CBCT. A respiration monitor of abdominal displacement was used during all scans. In addition to a CBCT reconstruction without motion correction, the motion correction method was applied to the same 1-min scan. Projection images were sorted into ten bins based on abdominal displacement, and each bin was reconstructed to produce ten intermediate CBCT images. Each intermediate CBCT was deformed to the end expiration state using a motion model derived from RCCT. The deformed intermediate CBCT images were then added to produce a final RMC-CBCT. In order to evaluate the second study goal, the CBCT was corrected in two ways, one using a model derived from the RCCT at simulation [RMC-CBCT(sim)], the other from the RCCT at treatment [RMC-CBCT(tx)]. Image evaluation compared uncorrected CBCT, RMC-CBCT(sim), and RMC-CBCT(tx). The gated CBCT at end expiration served as the criterion standard for comparison. Using automatic rigid image
