  6. Focus: Global histories of science. Introduction.

    Sivasundaram, Sujit

    2010-03-01

    An interest in global histories of science is not new. Yet the project envisioned by this Focus section is different from that pursued by natural historians and natural philosophers in the early modern age. Instead of tracing universal patterns, there is value in attending to the connections and disconnections of science on the global stage. Instead of assuming the precision of science's boundaries, historians might consider the categories of "science" and "indigenous knowledge" to have emerged from globalization. New global histories of science will be characterized by critical reflection on the limits of generalization, as well as a creative adoption of new sources, methods, and chronologies, in an attempt to decenter the European history of science. Such a project holds the promise of opening up new conversations between historians, anthropologists, philosophers, and sociologists of science. It is of critical importance if the discipline is not to fragment into regional and national subfields or become dominated by structural frameworks such as imperialism.

    ; (5) seek institutional stability; and (6) design processes for learning. In addition, CSC outputs should help decision makers to embrace and focus on uncertainty rather than on attempts to reduce uncertainty. Model building can be a useful exercise if used as a broad intellectual exercise to understand systems instead of narrow projection-based efforts. In some cases DOI agencies may want very simple products including scientific syntheses. Social science work including but not limited to economics and policy should be considered when appropriate to decision maker needs. One method for allocating CSC resources would involve a limited number of small scoping meetings with climate sensitive regional DOI agencies. In the Southwest, for example, regional entities would include at least the Landscape Conservation Cooperatives, National Park Service, Fish and Wildlife Service, Bureau of Land Management, Reclamation and the US Forest Service, a critically important land manager with a well-funded and well-structured climate program. Given DOI's trust responsibility to the tribes, at least one project should be focused on meeting those needs in this region. The goal of these meetings would be to identify a small number of projects each with adequate funding for interdisciplinary teams of university and USGS scientists and DOI decision makers. Done correctly, the CSCs should be able to leverage resources with these DOI partners.

  10. Reimagining publics and (non)participation: Exploring exclusion from science communication through the experiences of low-income, minority ethnic groups.

    Dawson, Emily

    2018-01-01

    This article explores science communication from the perspective of those most at risk of exclusion, drawing on ethnographic fieldwork. I conducted five focus groups and 32 interviews with participants from low-income, minority ethnic backgrounds. Using theories of social reproduction and social justice, I argue that participation in science communication is marked by structural inequalities (particularly ethnicity and class) in two ways. First, participants' involvement in science communication practices was narrow (limited to science media consumption). Second, their experiences of exclusion centred on cultural imperialism (misrepresentation and 'Othering') and powerlessness (being unable to participate or change the terms of their participation). I argue that social reproduction in science communication constructs a narrow public that reflects the shape, values and practices of dominant groups, at the expense of the marginalised. The article contributes to how we might reimagine science communication's publics by taking inclusion/exclusion and the effects of structural inequalities into account.

  11. Popper, laws, and the exclusion of biology from genuine science.

    2007-01-01

    The primary purpose of this paper is to argue that biologists should stop citing Karl Popper on what a genuinely scientific theory is. Various ways in which biologists cite Popper on this matter are surveyed, including the use of Popper to settle debates on methodology in phylogenetic systematics. It is then argued that the received view on Popper--namely, that a genuinely scientific theory is an empirically falsifiable one--is seriously mistaken, that Popper's real view was that genuinely scientific theories have the form of statements of laws of nature. It is then argued that biology arguably has no genuine laws of its own. In place of Popperian falsifiability, it is suggested that a cluster class epistemic values approach (which subsumes empirical falsifiability) is the best solution to the demarcation problem between genuine science and pseudo- or non-science.

  12. Focus: science, history, and modern India. Introduction.

    Science.gov (United States)

    Phalkey, Jahnavi

    2013-06-01

    Histories of science in India are revisitations of the colonial question. Science is ideology to be unraveled and exposed--as modernity and progress making or violence and oppression making--depending on where you stand on the interpretive spectrum. It has been seen as ideologically driven practice, as a mode of knowledge production whose history is inseparable from the social and political uses to which it is tethered. In the colonial as well as the postcolonial context, science and technology have been seen as the "ideology of empire," "tools of empire," "tentacles of progress," and "reasons of state." Yet science and technology are practices and bodies of knowledge that inhabitants of the subcontinent have engaged with enthusiasm, that they have used to invent themselves in their global, national, and individual lives. We know remarkably little about the histories of these complex engagements. A departure from current historiographical preoccupations is called for to map and explain the lives, institutions, practices, and stories of science on the subcontinent as they connect with, and where they break away from, the world at large.

    2018-01-01

    The 6-month exclusive breastfeeding rate in the Northeast region of Thailand has recently significantly decreased in contrast to all other regions in Thailand. The factors that have influenced this decrease remain unknown. Hence, it is suggested that an investigation into factors that could improve or hinder EBF for 6 months in Northeast Thailand may be required to inform the development of relevant interventions to improve this situation. This study aimed to identify perceived facilitators and barriers to providing exclusive breastfeeding for 6 months in Northeast Thailand among breastfeeding mothers. Six focus group discussions were conducted with a total of 30 mothers aged 20 to 40 years who had children aged between 4 and 6 months and were currently breastfeeding or had breastfeeding experience. Participants were recruited through self-selection sampling from Khonkaen hospital (urban), Numphong hospital (peri-urban) and private hospitals (urban) in Khonkaen, Thailand. Thematic analysis was employed to analyse the data. Five main themes, with 10 sub-themes, were identified as either facilitators (+) or barriers (-), or in some cases, as both (+/-). Breastfeeding knowledge, perceptions, maternal circumstances, support, and traditional food were the main identified themes. Mother's breastfeeding knowledge, intention to breastfeed, and social media were perceived as facilitators. Perceptions, employment, and formula milk promotion were perceived as barriers. Family, healthcare, and traditional food were perceived as both facilitators and barriers. The perception that social media was a way to access breastfeeding knowledge and support mothers in Northeast Thailand emerged as a new facilitating factor that had not previously been identified in Thai literature relating to facilitators and barriers to exclusive breastfeeding. Intention to breastfeed, family support, healthcare support and traditional food were mentioned by all groups, whereas mothers from urban

    2015-09-01

    Historians of science see knowledge and its claimants as constrained by myriad factors. These limitations range from the assumptions and commitments of scientific practitioners to the material and ideational contexts of their practice. The precise nature of such limits and the relations among them remains an open question in the history of science. The essays in this Focus section address this question by examining one influential portrayal of constraints--Herbert Simon's theory of "bounded rationality"--as well as the responses to which it has given rise over the last half century.

    2010-06-01

    Twenty years after the fall of the Berlin Wall, the Cold War looks ever more like a slice of history rather than a contemporary reality. During those same twenty years, scholarship on science, technology, and the state during the Cold War era has expanded dramatically. Building on major studies of physics in the American context--often couched in terms of "big science"--recent work has broached scientific efforts in other domains as well, scrutinizing Cold War scholarship in increasingly international and comparative frameworks. The essays in this Focus section take stock of current thinking about science and the Cold War, revisiting the question of how best to understand tangled (and sometimes surprising) relationships between government patronage and the world of ideas.

    Congress` decision to close down the $11 billion Superconducting Supercollider is spreading anxiety throughout the scientific community. As funding for the nation`s research laboratories becomes increasingly scarce, technical communicators in these organizations must focus much of their communications efforts on a new culture: Congress and the public. We discuss how to characterize this new audience and the importance of evaluating communication products, and we highlight some strategies for interpreting science to nonscientists more effectively.

  17. van Eijck and Roth's utilitarian science education: why the recalibration of science and traditional ecological knowledge invokes multiple perspectives to protect science education from being exclusive

    Science.gov (United States)

    Mueller, Michael P.; Tippins, Deborah J.

    2010-12-01

    This article is a philosophical analysis of van Eijck and Roth's (2007) claim that science and traditional ecological knowledge (TEK) should be recalibrated because they are incommensurate, particular to the local contexts in which they are practical. In this view, science maintains an incommensurate status as if it is a "fundamental" basis for the relative comparison of other cultural knowledges, which reduces traditional knowledge to a status of in relation to the prioritized (higher)-status of natural sciences. van Eijck and Roth reject epistemological Truth as a way of thinking about sciences in science education. Rather they adopt a utilitarian perspective of cultural-historical activity theory to demonstrate when traditional knowledge is considered science and when it is not considered science, for the purposes of evaluating what should be included in U.S. science education curricula. There are several challenges for evaluating what should be included in science education when traditional knowledges and sciences are considered in light of a utilitarian analysis. Science as diverse, either practically local or theoretically abstract, is highly uncertain, which provides opportunities for multiple perspectives to enlarge and protect the natural sciences from exclusivity. In this response to van Eijck and Roth, we make the case for considering dialectical relationships between science and TEK in order to ensure cultural diversity in science education, as a paradigm. We also emphasize the need to (re)dissolve the hierarchies and dualisms that may emerge when science is elevated in status in comparison with other knowledges. We conclude with a modification to van Eijck and Roth's perspective by recommending a guiding principle of cultural diversity in science education as a way to make curriculum choices. We envision this principle can be applied when evaluating science curricula worldwide.

  18. Evaluation of factors influencing on non-exclusive breast feeding during the first six months of life in Bushehr Port using focus group discussion

    Full Text Available Non-exclusive breast feeding in the early years of life is one of the most important factors in growth and development of infants. Therefore, exclusive breast feeding is recommended during the first six months of life. For determining the effective factors of non-exclusive breast feeding during the first six months of life, we used focus group discussion by participation of 60 mothers who had an infant under 6 months age and enjoyed non-exclusive breast feeding. Mothers divided into eight groups considering their occupation and number of child. All groups reported scanty of mother’s milk, mother’s occupation, mother’s illness, mother’s comfort, wrong beliefs, infant’s illness, doctors and health care providers recommendations, infant’s dependency to feeding bottle and pacifiers as the most frequent factors in using nonexclusive breast feeding. All mothers believed that health care centers, relatives and older members of family, books and pamphlets, mass media, physicians were their effective sources of awareness and promotion of exclusive breast feeding. Considering the presented ideas in all groups, it is realized that mothers during their pregnancy have sparse information about exclusive breast feeding and because of lack of enough essential training, some socio – cultural beliefs affects non-exclusive breast feeding. Mass media and especial training programs should be implemented to promote exclusive breast feeding in Bushehr Port.

    Basic research in surface and interface science is highly interdisciplinary, covering the fields of physics, chemistry, biophysics, geo-, atmospheric and environmental sciences, material science, chemical engineering, and more. The various phenomena are interesting by themselves, and they are most important in nearly all modern technologies, as for example electronic, magnetic, and optical devices, sensors, catalysts, lubricants, hard and thermal-barrier coatings, protection against corrosion and crack formation under harsh environments. In fact, detailed understanding of the elementary processes at surfaces is necessary to support and to advance the high technology that very much founds the prosperity and lifestyle of our society. Current state-of-the-art experimental studies of elementary processes at surfaces, of surface properties and functions employ a variety of sophisticated tools. Some are capable of revealing the location and motion of individual atoms. Others measure excitations (electronic, magnetic and vibronic), employing, for example, special light sources such as synchrotrons, high magnetic fields, or free electron lasers. The surprising variety of intriguing physical phenomena at surfaces, interfaces, and nanostructures also pose a persistent challenge for the development of theoretical descriptions, methods, and even basic physical concepts. This second focus issue on the topic of 'Advances in Surface and Interface Science' in New Journal of Physics, following on from last year's successful collection, provides an exciting synoptic view on the latest pertinent developments in the field.

    Recent advances in atmospheric sciences and hydrology have identified the key role of atmo-spheric rivers (ARs) in determining the distribution of strong precipitation events in the midlatitudes. The growth of the subject is evident in the increase in scientific publications that discuss ARs (Fig. 1a). Combined with related phenomena, that is, warm conveyor belts (WCBs) and tropical moisture exports (TMEs), the frequency, position, and strength of ARs determine the occurrence of floods, droughts, and water resources in many parts of the world. A conference at the Scripps Institution of Oceanography in La Jolla, California, recently gathered over 100 experts in atmospheric, hydrologic, oceanic, and polar science; ecology; water management; and civil engineering to assess the state of AR science and to explore the need for new information. This first International Atmospheric Rivers Conference (IARC) allowed for much needed introductions and interactions across fields and regions, for example, participants came from five continents, and studies covered ARs in six continents and Greenland (Fig. 1b). IARC also fostered discussions of the status and future of AR science, and attendees strongly supported the idea of holding another IARC at the Scripps Institution of Oceanography in the summer of 2018.

    Supramolecular chemistry is an extremely useful and important domain for understanding pharmaceutical sciences because various physiological reactions and drug activities are based on supramolecular chemistry. However, it is not a major domain in the pharmaceutical field. In this review, we propose a new concept in pharmaceutical sciences termed "supramolecular pharmaceutical sciences," which combines pharmaceutical sciences and supramolecular chemistry. This concept could be useful for developing new ideas, methods, hypotheses, strategies, materials, and mechanisms in pharmaceutical sciences. Herein, we focus on cyclodextrin (CyD)-based supermolecules, because CyDs have been used not only as pharmaceutical excipients or active pharmaceutical ingredients but also as components of supermolecules.

  5. The Priority of the Question: Focus Questions for Sustained Reasoning in Science

    Science.gov (United States)

    Lustick, David

    2010-08-01

    Science education standards place a high priority on promoting the skills and dispositions associated with inquiry at all levels of learning. Yet, the questions teachers employ to foster sustained reasoning are most likely borrowed from a textbook, lab manual, or worksheet. Such generic questions generated for a mass audience, lack authenticity and contextual cues that allow learners to immediately appreciate a question’s relevance. Teacher queries intended to motivate, guide, and foster learning through inquiry are known as focus questions. This theoretical article draws upon science education research to present a typology and conceptual framework intended to support science teacher educators as they identify, develop, and evaluate focus questions with their students.

  7. Competitive exclusion: an ecological model demonstrates how research metrics can drive women out of science

    O'Brien, K.; Hapgood, K.

    2012-12-01

    While universities are often perceived within the wider population as a flexible family-friendly work environment, continuous full-time employment remains the norm in tenure track roles. This traditional career path is strongly re-inforced by research metrics, which typically measure accumulated historical performance. There is a strong feedback between historical and future research output, and there is a minimum threshold of research output below which it becomes very difficult to attract funding, high quality students and collaborators. The competing timescales of female fertility and establishment of a research career mean that many women do not exceed this threshold before having children. Using a mathematical model taken from an ecological analogy, we demonstrate how these mechanisms create substantial barriers to pursuing a research career while working part-time or returning from extended parental leave. The model highlights a conundrum for research managers: metrics can promote research productivity and excellence within an organisation, but can classify highly capable scientists as poor performers simply because they have not followed the traditional career path of continuous full-time employment. Based on this analysis, we make concrete recommendations for researchers and managers seeking to retain the skills and training invested in female scientists. We also provide survival tactics for women and men who wish to pursue a career in science while also spending substantial time and energy raising their family.

    The goal of the NIH Science of Behavior Change (SOBC) Common Fund Program is to provide the basis for an experimental medicine approach to behavior change that focuses on identifying and measuring the mechanisms that underlie behavioral patterns we are trying to change. This paper frames the development of the program within a discussion of the substantial disease burden in the U.S. attributable to behavioral factors, and details our strategies for breaking down the disease- and condition-focused silos in the behavior change field to accelerate discovery and translation. These principles serve as the foundation for our vision for a unified science of behavior change at the NIH and in the broader research community. Copyright © 2017. Published by Elsevier Ltd.

    2018-04-01

    We assessed the real-life use of direct oral anticoagulants (DOACs) in patients with venous thromboembolism (VTE) and exclusion criteria for randomized trials. From 2013 to 2016, 3,578 of 18,853 patients (19%) had exclusion criteria. Irrespective of which anticoagulant was chosen, they had more VTE recurrences (hazard ratio (HR): 3.10; 95% confidence interval (CI): 2.47-3.88), major bleeds (HR: 4.10; 95% CI: 3.38-4.96), and deaths (HR: 9.47; 95% CI: 8.46-10.6) than those without exclusion criteria. During initial therapy, no patient with exclusion criteria on DOACs (n = 115) recurred, but those on rivaroxaban bled less often (adjusted HR: 0.18; 95% CI: 0.04-0.79) than those on unfractionated heparin (n = 224) and similar to those (n = 3,172) on low-molecular-weight (LMWH) heparin. For long-term therapy, patients on rivaroxaban (n = 151) had nonsignificantly fewer VTE recurrences (adjusted HR: 0.74; 95% CI: 0.08-1.32) and major bleeds (adjusted HR: 0.41; 95% CI: 0.15-1.15) than those on LMWH (n = 2,071). The efficacy and safety of DOACs were similar to standard therapy. © 2017 American Society for Clinical Pharmacology and Therapeutics.

  15. Guiding students towards sensemaking: teacher questions focused on integrating scientific practices with science content

    2017-10-01

    Science education reforms articulate a vision of ambitious science teaching where teachers engage students in sensemaking discussions and emphasise the integration of scientific practices with science content. Learning to teach in this way is complex, and there are few examples of sensemaking discussions in schools where textbook lessons and teacher-directed discussions are the norm. The purpose of this study was to characterise the questioning practices of an experienced teacher who taught a curricular unit enhanced with educative features that emphasised students' engagement in scientific practices integrated with science content. Analyses indicated the teacher asked four types of questions: explication questions, explanation questions, science concept questions, and scientific practice questions, and she used three questioning patterns including: (1) focusing students on scientific practices, which involved a sequence of questions to turn students back to the scientific practice; (2) supporting students in naming observed phenomena, which involved a sequence of questions to help students use scientific language; and (3) guiding students in sensemaking, which involved a sequence of questions to help students learn about scientific practices, describe evidence, and develop explanations. Although many of the discussions in this study were not yet student-centred, they provide an image of a teacher asking specific questions that move students towards reform-oriented instruction. Implications for classroom practice are discussed and recommendations for future research are provided.

    Dijkstra, Elma; Goedhart, Martin

    2011-07-01

    Background and purpose This study examines secondary-school students' opinions on participating in authentic science projects which are part of an international EU project on climate change research in seven countries. Partnerships between schools and research institutes result in student projects, in which students work with and learn from scientists about the global carbon cycle. This study focuses in particular on differences between male and female students, as female students normally like traditional school science less than male students. Sample and design Data, drawn from 1370 students from 60 secondary schools across Europe, were collected through questionnaires taken at the end of the projects. The evaluated aspects were: organization; enjoyment; difficulty; and impact of the projects. Results The findings suggest that authentic science education is appreciated very much by both male students and even more by female students. The projects had positive impacts on climate change ideas, in particular for female students. Female students felt that they had learned many new things more often than male students. Conclusions Both male and female students have positive opinions about the authentic science projects. The results further point to positive effects of activities in which students have an active role, like hands-on experiments or presentation of results. The findings are placed in the international context of science education and their implications for policy are discussed.

    2015-12-01

    Empirical studies show that academia is socially exclusive. I argue that this social exclusion works, at least partly, through the systematic methodological disqualification of contributions from members of underrepresented social groups. As methodological quality criteria are underdetermined their interpretation and weighting can be biased with relation to gender, race, social background, etc. Such biased quality evaluation can take place on a local or global level. The current situation of women in academic philosophy illuminates this. I conclude that only mechanical solutions can effectively change the situation. Copyright © 2015 Elsevier Ltd.

    Full Text Available Theoretical work that seeks to highlight the possible reasons why the STS approach has not effectively be inserted in the educational process and point out alternative to its insertion. It thus explores the origin of the STS movement and discusses its focus on education, science teaching and teacher education. It is a study in a critical perspective, from a documentary research focused on scientific production published in books, theses, papers presented in conference proceedings and journals in the field of education. The readings allowed direct the discussions, assuming the interpretative analysis for the organization of the text. The study shows that teacher education, the problems presented in its theoretical and epistemological aspects and ethical, is the main obstacle to the insertion of the STS approach in the educational process. Alternatively, points to issues of social-scientific approach to STS approach in a complementary perspective, as the possibility of improvements in the aspects highlighted

  19. The Pitfalls of a Tool-based Science and the Promise of a Problem-focused Science

    2011-05-01

    Full Text Available Our present social sciences are at risk of losing sight of their primary purpose: the goal of reducing uncertainty. For years social scientists have drifted slowly toward the routine of employing of accepted methodological, conceptual, and analytical tools rather than engaging in problem oriented inquiry. Scientific contributions are reviewed in accordance to their compliance with the routine application of tools rather than focusing on their ability to problem-solve for a wider population. Researchers in every area of psychology for instance now insist on using methods such as random assignment and control groups, as well as data analytic procedures such as null hypothesis significance testing without regard to their relevance. A problem-focused inquiry would not dictate the routine use of any particular tool but rather the judicious application of tools when deemed appropriate. The following article describes  the current situation in the framework contrasting toolbased and problem-focused inquiry and offers several insights that may create a more balanced and fruitful approach to scientific inquiry. DOI: 10.2458/azu_jmmss.v1i2.99

    2017-01-01

    Social exclusion anxiety is a term which builds on a social-psychological concept of human beings as existentially dependent on social embeddedness. This entry explores the concept in relation to bullying among children, which is a widespread and serious problem in schools and institutions. Social...... exclusion anxiety and longing for belonging are both central aspects of the affects and processes that enact and challenge social groups. Social exclusion anxiety should not be confused with ‘social phobia’, which is a concept within clinical psychology that focuses on the individual and refers to a phobic...... psychological condition. Social exclusion anxiety instead points to a distributed affect which circulates and smolders in all social groups. This is the result of an ever-present risk of someone being judged unworthy to belong to, or deemed not a legitimate participant in, a social group. Such anxiety may...

  1. Cascadia GeoSciences: Community-Based Earth Science Research Focused on Geologic Hazard Assessment and Environmental Restoration.

    Science.gov (United States)

    2007-12-01

    Cascadia GeoSciences (CG) is a new non-profit membership governed corporation whose main objectives are to conduct and promote interdisciplinary community based earth science research. The primary focus of CG is on geologic hazard assessment and environmental restoration in the Western U.S. The primary geographic region of interest is Humboldt Bay, NW California, within the southern Cascadia subduction zone (SCSZ). This region is the on-land portion of the accretionary prism to the SCSZ, a unique and exciting setting with numerous hazards in an active, dynamic geologic environment. Humboldt Bay is also a region rich in history. Timber harvesting has been occurring in California's coastal forestlands for approximately 150 years. Timber products transported with ships and railroads from Mendocino and Humboldt Counties helped rebuild San Francisco after the 1906 earthquake. Historic land-use of this type now commonly requires the services of geologists, engineers, and biologists to restore road networks as well as provide safe fish passage. While Humboldt Bay is a focus of some of our individual research goals, we welcome regional scientists to utilize CG to support its mission while achieving their goals. An important function of CG is to provide student opportunities in field research. One of the primary charitable contributions of the organization is a student grant competition. Funds for the student grant will come from member fees and contributions, as well as a percent of all grants awarded to CG. A panel will review and select the student research proposal annually. In addition to supporting student research financially, professional members of CG will donate their time as mentors to the student researchers, promoting a student mentor program. The Humboldt Bay region is well suited to support annual student research. Thorough research like this will help unravel some of the mysteries of regional earthquake-induced land-level changes, as well as possible fault

    Abstract This article suggests to focus on the history of human variation instead of focussing on the history of race science. It views the latter as a subset of the former, hence views race science as embedded into the larger field of life scientists' investigations into human variation. This paper explores why human variation is such an attractive and productive object particularly for the life sciences. It proposes that knowledge about human variation is incomplete in a promising way, and ...

    Citizen science projects, which engage non-professional scientists in one or more stages of scientific research, have been gaining popularity; yet maintaining participants’ activity level over time remains a challenge. The objective of this study was to evaluate the potential for a short-term, focused campaign to increase participant activity in a national-scale citizen science program. The campaign that we implemented was designed to answer a compelling scientific question. We invited participants in the phenology-observing program, Nature’s Notebook, to track trees throughout the spring of 2012, to ascertain whether the season arrived as early as the anomalous spring of 2010. Consisting of a series of six electronic newsletters and costing our office slightly more than 1 week of staff resources, our effort was successful; compared with previous years, the number of observations collected in the region where the campaign was run increased by 184%, the number of participants submitting observations increased by 116%, and the number of trees registered increased by 110%. In comparison, these respective metrics grew by 25, 55, and 44%, over previous years, in the southeastern quadrant of the United States, where no such campaign was carried out. The campaign approach we describe here is a model that could be adapted by a wide variety of programs to increase engagement and thereby positively influence participant retention.

    2013-12-01

    The "global turn" in the history of science offers new ways to think about how to do national and regional histories of science, in this case the history of science in Latin America. For example, it questions structuralist and diffusionist models of the spread of science and shows the often active role that people in Latin America (and the rest of the Global South) played in the construction of "universal" scientific knowledge. It suggests that even national or regional histories of science must be situated in a global context; all too often, such histories have treated global processes as a distant backdrop. At the same time, historians need to pay constant attention to the role of power in the construction of scientific knowledge. Finally, this essay highlights a methodological tool for writing globally inflected histories of science: the method of "following".

  9. IAEA Meeting Focuses on Nuclear and Isotopic Science to Protect Oceans

    International Nuclear Information System (INIS)

    2013-01-01

    Full text: The marine ecosystems that keep the oceans healthy are subject to increasing stress. Levels of acidity are rising in a process that is taking place at a more rapid pace than ever observed before. This poses risks to all life in the ocean - and all who depend on the oceans. Starting today, some of the world's top marine scientists are meeting in Vienna to discuss this multi-faceted problem and ways to tackle it. Science conducted and coordinated by the IAEA that uses isotopic techniques plays a key role in learning about ocean acidification and its effects. ''In dealing with threats to the health of the seas, governments need accurate data. For that, they need skilled researchers who can devise accurate models to help predict future conditions. That way, governments can start implementing the appropriate strategies to protect the seas and oceans,'' IAEA Director General Yukiya Amano told participants in the IAEA's Scientific Forum, titled The Blue Planet - Nuclear Applications for a Sustainable Marine Environment. ''The IAEA helps to make this possible. We promote a comprehensive approach to the study, monitoring and protection of marine, coastal and terrestrial ecosystems. We support effective global cooperation to address the threats to our oceans.'' The oceans not only produce as much as half of the world's oxygen; they also absorb more than a quarter of man-made CO 2 . This reduces the greenhouse effect, but it also increases the acidity of seawater, resulting in a hostile environment for calciferous plankton, crustaceans, molluscs and coral reefs. With all parts of the ecosystem connected, all life in the oceans suffers from the increased level of acidity. The two-day Forum, held on the sidelines of the IAEA's annual General Conference, is divided into three sessions. The first session focuses on the pressures faced by the coastal and marine systems and the need for partnerships and science to develop targeted responses. The second session addresses

  10. Using focus groups to design systems science models that promote oral health equity.

    While the US population overall has experienced improvements in oral health over the past 60 years, oral diseases remain among the most common chronic conditions across the life course. Further, lack of access to oral health care contributes to profound and enduring oral health inequities worldwide. Vulnerable and underserved populations who commonly lack access to oral health care include racial/ethnic minority older adults living in urban environments. The aim of this study was to use a systematic approach to explicate cause and effect relationships in creating a causal map, a type of concept map in which the links between nodes represent causality or influence. To improve our mental models of the real world and devise strategies to promote oral health equity, methods including system dynamics, agent-based modeling, geographic information science, and social network simulation have been leveraged by the research team. The practice of systems science modeling is situated amidst an ongoing modeling process of observing the real world, formulating mental models of how it works, setting decision rules to guide behavior, and from these heuristics, making decisions that in turn affect the state of the real world. Qualitative data were obtained from focus groups conducted with community-dwelling older adults who self-identify as African American, Dominican, or Puerto Rican to elicit their lived experiences in accessing oral health care in their northern Manhattan neighborhoods. The findings of this study support the multi-dimensional and multi-level perspective of access to oral health care and affirm a theorized discrepancy in fit between available dental providers and patients. The lack of information about oral health at the community level may be compromising the use and quality of oral health care among racial/ethnic minority older adults. Well-informed community members may fill critical roles in oral health promotion, as they are viewed as highly credible

  11. Understanding public opinion in debates over biomedical research: looking beyond political partisanship to focus on beliefs about science and society.

    Directory of Open Access Journals (Sweden)

    Matthew Nisbet

    Full Text Available As social scientists have investigated the political and social factors influencing public opinion in science-related policy debates, there has been growing interest in the implications of this research for public communication and outreach. Given the level of political polarization in the United States, much of the focus has been on partisan differences in public opinion, the strategies employed by political leaders and advocates that promote those differences, and the counter-strategies for overcoming them. Yet this focus on partisan differences tends to overlook the processes by which core beliefs about science and society impact public opinion and how these schema are often activated by specific frames of reference embedded in media coverage and popular discourse. In this study, analyzing cross-sectional, nationally representative survey data collected between 2002 and 2010, we investigate the relative influence of political partisanship and science-related schema on Americans' support for embryonic stem cell research. In comparison to the influence of partisan identity, our findings suggest that generalized beliefs about science and society were more chronically accessible, less volatile in relation to media attention and focusing events, and an overall stronger influence on public opinion. Classifying respondents into four unique audience groups based on their beliefs about science and society, we additionally find that individuals within each of these groups split relatively evenly by partisanship but differ on other important dimensions. The implications for public engagement and future research on controversies related to biomedical science are discussed.

  15. Experiences of exclusion when living on a ventilator: reflections based on the application of Julia Kristeva's philosophy to caring science.

    Science.gov (United States)

    Lindahl, Berit

    2011-01-01

    The research presented in this work represents reflections in the light of Julia Kristeva's philosophy concerning empirical data drawn from research describing the everyday life of people dependent on ventilators. It also presents a qualitative and narrative methodological approach from a person-centred perspective. Most research on home ventilator treatment is biomedical. There are a few published studies describing the situation of people living at home on a ventilator but no previous publications have used the thoughts in Kristeva's philosophy applied to this topic from a caring science perspective. The paper also addresses what a life at home on a ventilator may be like and will hopefully add some new aspects to the discussion of philosophical issues in nursing and the very essence of care. Kristeva's philosophy embraces phenomena such as language, abjection, body, and love, allowing her writings to make a fruitful contribution to nursing philosophy in that they strengthen, expand, and deepen a caring perspective. Moreover, her writings about revolt having the power to create hope add an interesting aspect to the work of earlier philosophers and nursing theorists. © 2010 Blackwell Publishing Ltd.

    Today, the challenges of quality improvement and customer focus as well as systems development are important and inevitable matters in higher education institutes. There are some highly competitive challenges among educational institutes, including accountability to social needs, increasing costs of education, diversity in educational methods and centers and their consequent increasing competition, and the need for adaptation of new information and knowledge to focus on students as the main customers. Hence, the purpose of this study was to determine the rate of costumer focus based on Isfahan University of Medical Sciences students' viewpoints and to suggest solutions to improve this rate. This was a cross-sectional study carried out in 2011. The statistical population included all the students of seven faculties of Isfahan University of Medical Sciences. According to statistical formulae, the sample size consisted of 384 subjects. Data collection tools included researcher-made questionnaire whose reliability was found to be 87% by Cronbach's alpha coefficient. Finally, using the SPSS statistical software and statistical methods of independent t-test and one-way analysis of variance (ANOVA), Likert scale based data were analyzed. The mean of overall score for customer focus (student-centered) of Isfahan University of Medical Sciences was 46.54. Finally, there was a relation between the mean of overall score for customer focus and gender, educational levels, and students' faculties. Researcher suggest more investigation between Medical University and others. It is a difference between medical sciences universities and others regarding the customer focus area, since students' gender must be considered as an effective factor in giving healthcare services quality. In order to improve the customer focus, it is essential to take facilities, field of study, faculties, and syllabus into consideration.

    "Water in the Solar System" is an out-of-school time (OST) science education activity for middle school students that was developed as part of the Planetary Learning that Advances the Nexus of Engineering, Technology, and Science (PLANETS) project. The PLANETS project was selected in support of the NASA Science Mission Directorate's Science Education Cooperative Agreement Notice, with the goal of developing and disseminating OST curriculum and related professional development modules that integrate planetary science, technology, and engineering. "Water in the Solar System" is a science activity that addresses the abundance and availability of water in the solar system. The activity consists of three exercises based on the following guiding questions: 1) How much water is there on the Earth? 2) Where can you find water in the solar system? and 3) What properties affect whether or not water can be used by astronauts? The three exercises involve a scaling relationship demonstration about the abundance of useable water on Earth, a card game to explore where water is found in the solar system, and a hands-on exercise to investigate pH and salinity. Through these activities students learn that although there is a lot of water on Earth, most of it is not in a form that is accessible for humans to use. They also learn that most water in the solar system is actually farther from the sun, and that properties such as salinity and pH affect whether water can be used by humans. In addition to content for students, the activity includes background information for educators, and links to in-depth descriptions of the science content. "Water in the Solar System" was developed through collaboration between subject matter experts at the USGS Astrogeology Science Center, and curriculum and professional development experts in the Center for Science Teaching and Learning at Northern Arizona University. Here we describe our process of curriculum development, education objectives of

    2013-06-01

    A recent report of the United States' Presidential Commission for the Study of Bioethical Issues highlights how important it is for the research community to enjoy the "earned confidence" of the public and how creating a "culture of responsibility" can contribute to that confidence. It identifies a major role for "creative, flexible, and innovative" ethics education in creating such a culture. Other recent governmental reports from various nations similarly call for a renewed emphasis on ethics education in the sciences. We discuss why some common approaches to ethics education in the graduate sciences fail to meet the goals envisioned in the reports and we describe an approach, animated by primary attention on excellent science as opposed to bad scientists, that we have employed in our ethics teaching that we think is better suited for inspiring and sustaining responsible, trustworthy science. © 2013 Wiley Periodicals, Inc.

    In the past ten years, increasing evidence has demonstrated that scientific teaching and active learning improve student retention and learning gains in the sciences. Graduate teaching assistants (GTAs), who play an important role in undergraduate education at many universities, require training in these methods to encourage implementation, long-term adoption, and advocacy. Here, we describe the design and evaluation of a two-day training workshop for first-year GTAs in the life sciences. This workshop combines instruction in current research and theory supporting teaching science through active learning as well as opportunities for participants to practice teaching and receive feedback from peers and mentors. Postworkshop assessments indicated that GTA participants' knowledge of key topics increased during the workshop. In follow-up evaluations, participants reported that the workshop helped them prepare for teaching. This workshop design can easily be adapted to a wide range of science disciplines. Overall, the workshop prepares graduate students to engage, include, and support undergraduates from a variety of backgrounds when teaching in the sciences. © 2018 by The International Union of Biochemistry and Molecular Biology, 2018. © 2018 The International Union of Biochemistry and Molecular Biology.

    Jon Amiel, director of the 2003 science fiction blockbuster movie The Core, told a room packed with geophysicists at the recent AGU Fall Meeting that he had a confession to make. The confession had nothing to do with what he called the “preposterous premises” of the movie, including that humans could start or stop the spinning of Earth's core. Rather, he told the crowd at the Tuesday evening presentation “Science and the Cinema: AGU Sciences Meet Hollywood” about his recurring dream of being on stage wearing nothing but a skimpy T-shirt. “This dream now has come true. Here I am, I'm talking to a whole room of geophysicists about The Core. I've never felt like the T-shirt was this short,” he said.

    Social networks have been used to teach and engage people about the importance of science. The integration of social networks in the daily routines of faculties and scientists is strongly recommended to increase their personal brand, improve their skills, enhance their visibility, share and communicate science to society, promote scientific culture, and even as a tool for teaching and learning. Here we review the use of Twitter in science and comment on our previous experience of using this social network as a platform for a Massive Online Open Course (MOOC) in Spain and Latin America. We propose to extend this strategy to a pan-European Microbiology MOOC in the near future. © FEMS 2017. All rights reserved. For permissions, please e-mail: journals.permissions@oup.com.

  16. Mentoring a new science teacher in reform-based ways: A focus on inquiry

    Science.gov (United States)

    Schomer, Scott D.

    The processes, understandings, and uses of inquiry are identified by the National Science Education Standards (National Research Council, 1996) as a key component of science instruction. Currently, there are few examples in the literature demonstrating how teachers go about co-constructing inquiry-based activities and how mentors can promote the use of reform-based practices by novices. The purpose of this interpretive case study was to investigate how a mentor and her protege collaboratively developed, implemented and assessed three inquiry-based experiences. The questions that guided this research were: (1) How does the mentor assist protege growth in the development, implementation and assessment of inquiry-based experiences for secondary science students? (2) How are the protege's perceptions of inquiry influenced by her participation in developing, implementing and assessing inquiry-based experiences for secondary science students? The co-construction of the inquiry activities and the facilitation provided by the mentor represented Lev Vygotsky's (1978) social construction of information as the mentor guided the protege beyond her cognitive zone of proximal development. The participants in this study were a veteran science teacher who was obtaining her mentor certification, or Teacher Support Specialist, and her protege who was a science teacher in the induction phase of her career. Data were collected through in-depth, semi-structured interviews, tape recordings of planning sessions, researcher field notes, and email reflections during the co-construction process. Inductive analysis of the data led to the identification of common categories and subsequent findings, which reflected what the mentor and protege discussed about inquiry and the process of collaboration. The six themes that emerged from this study led to several implications that are significant for science teacher preparation and the mentoring community. The teachers indicated tools, such as the

    We produced two fun-to-play card games with the theme, The Nexus of Energy, Water, and Climate, that directly support teaching to the NGSS. In the games, players come to understand how demand for energy, water use, and climate change are tightly intertwined. Analysis by scientists from the national laboratories ensured that the games are reflect current data and research. The games have been tested with high school and informal science educators and their students and have received a formal evaluation. The games website http://isenm.org/games-for-learning shows how the games align with the NGSS, the Common Core, and the NRC's Strands of Science Learning. It also contains an extensive collection of accessible articles on the nexus to support use of the games in instruction. Thirst for Power is a challenging resource management game. Players, acting as governors of regions, compete to be the first to meet their citizens' energy needs. A governor can choose from a variety of carbon-based or renewable energy sources, but each source uses water and has an environmental—including climate change—impact. Energy needs must be met using only the water resources allocated to the region and without exceeding the environmental impact limit. "ACTION" cards alter game play and increase competition. Challenge and Persuade is a game of scientific argumentation, using evidence on nexus-related fact cards. Players must evaluate information, develop fact-based arguments, and communicate their findings. One card deck contains a set of adjectives, a second a series of fact cards. Players use their fact cards to make the best argument that aligns with an adjective selected by the "Judge". Players take turns being the "Judge," who determines who made the best argument. The games particularly align with NGSS elements: Connections to Engineering, Technology, and Application of Science. Players come to understand the science and engineering behind many energy sources and their impacts

    Over the last four years, the Green Ninja Project (GNP) has been developing educational media (e.g., videos, games and online lessons) to help motivate student interest and engagement around climate science and solutions. Inspired by the new emphasis in NGSS on climate change, human impact and engineering design, the GNP is developing a technology focused, integrative, and yearlong science curriculum focused around solutions to climate change. Recognizing the importance of teacher training on the successful implementation of NGSS, we have also integrated teacher professional development into our curriculum. During the presentation, we will describe the design philosophy around our middle school curriculum and share data from a series of classes that are piloting the curriculum during Fall 2015. We will also share our perspectives on how data, media creation and engineering can be used to create educational experiences that model the type of 'three-dimensional learning' encouraged by NGSS.

    The choice of geological disposal of high level radioactive waste is based on science. So, public understanding of science (PUS) becomes important issue in public acceptance (PA). Considering PUS, there are two problems. One is the literacy to understand scientific information and the other is the paradigm of the public on which the knowledge formed in the public depends heavily. In this research, survey of awareness and attitude to geological disposal on the postgraduate students was conducted. They have been studying civil and rock engineering, so they belong to 'the group' that acquires high education, culture and faculty. The results of questionnaires show that the awareness of danger is affected strongly by given information even in this groups, but they become thoughtful and prudent in their opinion and decision-making as increasing information.

    The scientific articles and Indoor Air conference publications of the indoor air sciences (IAS) during the last 50 years are summarized. In total 7524 presentations, from 79 countries, have been made at Indoor Air conferences held between 1978 (49 presentations) and 2014 (1049 presentations). In the Web of Science, 26 992 articles on indoor air research (with the word "indoor" as a search term) have been found (as of 1 Jan 2016) of which 70% were published during the last 10 years. The modern scientific history started in the 1970s with a question: "did indoor air pose a threat to health as did outdoor air?" Soon it was recognized that indoor air is more important, from a health point of view, than outdoor air. Topics of concern were first radon, environmental tobacco smoke, and lung cancer, followed by volatile organic compounds, formaldehyde and sick building syndrome, house dust-mites, asthma and allergies, Legionnaires disease, and other airborne infections. Later emerged dampness/mold-associated allergies and today's concern with "modern exposures-modern diseases." Ventilation, thermal comfort, indoor air chemistry, semi-volatile organic compounds, building simulation by computational fluid dynamics, and fine particulate matter are common topics today. From their beginning in Denmark and Sweden, then in the USA, the indoor air sciences now show increasing activity in East and Southeast Asia. © 2017 John Wiley & Sons A/S.

    Transformation of research in all biological fields necessitates the design, analysis and, interpretation of large data sets. Preparing students with the requisite skills in experimental design, statistical analysis, and interpretation, and mathematical reasoning will require both curricular reform and faculty who are willing and able to integrate mathematical and statistical concepts into their life science courses. A new Faculty Learning Community (FLC) was constituted each year for four years to assist in the transformation of the life sciences curriculum and faculty at a large, Midwestern research university. Participants were interviewed after participation and surveyed before and after participation to assess the impact of the FLC on their attitudes toward teaching, perceived pedagogical skills, and planned teaching practice. Overall, the FLC had a meaningful positive impact on participants' attitudes toward teaching, knowledge about teaching, and perceived pedagogical skills. Interestingly, confidence for viewing the classroom as a site for research about teaching declined. Implications for the creation and development of FLCs for science faculty are discussed. © 2016 by The International Union of Biochemistry and Molecular Biology, 44(6):517-525, 2016. © 2016 The International Union of Biochemistry and Molecular Biology.

    The U.S. National Science Education Standards provide guidelines for teaching science through inquiry, where students actively develop their understanding of science by combining scientific knowledge with reasoning and thinking skills. Inquiry activities include reading scientific literature, generating hypotheses, designing and carrying out investigations, interpreting data, and formulating conclusions. Inquiry-based instruction emphasizes questions, evidence, and explanation, the essential features of inquiry. We present two projects designed to develop learning materials for laboratory experiences in an undergraduate astronomy course. First, we engage students in inquiry-based learning by using "mini-journal” articles that follow the format of a scientific journal article, including a title, authors, abstract, introduction, methods, results, discussion and citations to peer-reviewed literature. The mini-journal provides a scaffold and serves as a springboard for students to develop and carry out their own follow-up investigation. They then present their findings in the form of their own mini-journal. This mini-journal format more directly reflects and encourages scientific practice. We use this technique in both introductory and upper level courses. The second project develops 3D virtual reality environments to help students interact with scientific constructs, and the use of collaborative learning tools to motivate student activity, deepen understanding and support knowledge building.

  5. Using a creativity-focused science program to foster general creativity in young children: A teacher action research study

    Science.gov (United States)

    Gomes, Joan Julieanne Mariani

    The importance of thinking and problem-solving skills, and the ability to integrate and analyze information has been recognized and yet may be lacking in schools. Creativity is inherently linked to problem finding, problem solving, and divergent thinking (Arieti, 1976; Csikszentmihalyi, 1990; Milgram, 1990). The importance of early childhood education and its role in the formation of young minds has been recognized (Caine & Caine, 1991; Montessori, 1967a, 1967b; Piaget, 1970). Early childhood education also impacts creativity (Gardner, 1999). The features of brain-based learning (Caine & Caine, 1991; Jensen, 1998; Sousa, 2001; Wolfe, 2001) have a clear connection to nurturing the creative potential in students. Intrinsic motivation and emotions affect student learning and creativity as well (Hennessey & Amabile, 1987). The purpose of this study was to discern if a creativity-focused science curriculum for the kindergarteners at a Montessori early learning center could increase creativity in students. This action research study included observations of the students in two classrooms, one using the creativity-focused science curriculum, and the other using the existing curriculum. The data collected for this interpretive study included interviews with the students, surveys and interviews with their parents and teachers, teacher observations, and the administration of Torrance's (1981) Thinking Creatively in Action and Movement (TCAM) test. The interpretation of the data indicated that the enhanced science curriculum played a role in enhancing the creativity of the children in the creativity-focused group. The results of the TCAM (Torrance, 1981) showed a significant increase in scores for the children in the creativity-focused group. The qualitative data revealed a heightened interest in science and the observation of creative traits, processes, and products in the creativity-focused group children. The implications of this study included the need for meaningful

    The peaceful application of atomic energy was introduced into Ghana about fifty years ago. This is the first bibliometric study of nuclear science and technology research publications originating from Ghana and listed in the International Nuclear Information System (INIS) Database. The purpose was to use the simple document counting method to determine the geographical distribution, annual growth and the subject areas of the publications as well as communication channels, key journals and authorship trends. The main findings of the study were that, a greater number of the nuclear science and technology records listed in the Database were published in Ghana (598 or 56.57% against 459 or 43.43% published outside Ghana). There has been a steady growth in the number of publications over the years with the most productive year being 2012. The main focus of research has been in the area of applied life sciences, comprising plant cultivation & breeding, pest & disease control, food protection and preservation, human nutrition and animal husbandry; followed by chemistry; environmental sciences; radiation protection; nuclear reactors; physics; energy; and radiology and nuclear medicine. The area with the least number of publications was safeguards and physical protection. The main channel of communicating research results was peer reviewed journals and a greater number of the journal articles were published in Ghana followed by the United Kingdom, Hungary and the Netherlands. The core journals identified in this study were Journal of Applied Science and Technology; Journal of Radioanalytical and Nuclear Chemistry; Journal of the Ghana Science Association; Radiation Protection Dosimetry; Journal of the Kumasi University of Science and Technology; West African Journal of Applied Ecology; Ghana Journal of Science; Applied Radiation and Isotopes; Annals of Nuclear Energy, IOP Conference Series (Earth and Environmental Science) and Radiation Physics and Chemistry.

    While access to computers, other technologies, and cyber-enabled resources that could be leveraged for enhancing student learning in science is increasing, generally it has been found that teachers use technology more for administrative purposes or to support traditional instruction. This use of technology, especially to support traditional instruction, sits in opposition to most recent standards documents in science education that call for student involvement in evidence-based sense-making activities. Many see technology as a potentially powerful resource that is reshaping society and has the potential to do the same in science classrooms. To consider the promise of technology in science classrooms, this research investigated the impact of a professional development project focused on enhancing teacher and student learning by using information and communication technologies (ICTs) for engaging students in reformed-based instruction. More specifically, these findings revealed positive teacher outcomes with respect to reformed-based and technology-supported instruction and increased ICT and new literacies skills. When considering students, the findings revealed positive outcomes with respect to ICT and new literacies skills and student achievement in science.

    Psychology as a science offers an enormous diversity of theories, principles, and methodological approaches to understand mental health, abnormal functions and behaviours and mental disorders. A selected overview of the scope, current topics as well as strength and gaps in Psychological Science may help to depict the advances needed to inform future research agendas specifically on mental health and mental disorders. From an integrative psychological perspective, most maladaptive health behaviours and mental disorders can be conceptualized as the result of developmental dysfunctions of psychological functions and processes as well as neurobiological and genetic processes that interact with the environment. The paper presents and discusses an integrative translational model, linking basic and experimental research with clinical research as well as population-based prospective-longitudinal studies. This model provides a conceptual framework to identify how individual vulnerabilities interact with environment over time, and promote critical behaviours that might act as proximal risk factors for ill-health and mental disorders. Within the models framework, such improved knowledge is also expected to better delineate targeted preventive and therapeutic interventions that prevent further escalation in early stages before the full disorder and further complications thereof develop. In contrast to conventional "personalized medicine" that typically targets individual (genetic) variation of patients who already have developed a disease to improve medical treatment, the proposed framework model, linked to a concerted funding programme of the "Science of Behaviour Change", carries the promise of improved diagnosis, treatment and prevention of health-risk behaviour constellations as well as mental disorders.

    The purpose of this study was to identify the key barriers to a customer-focused drug development process and develop a comprehensive framework to overcome them. The paper draws on existing literature, both academic and practitioner, across a range of disciplines (innovation management, marketing, organizational behavior, behavioral economics, health economics, industry reports). On the basis of this extensive review, a conceptual framework is developed that offers concrete suggestions on how organizations can overcome the barriers and enable a more customer-focused development process. The barriers to collaboration are organized into three distinct categories (economic, behavioral, organizational), and within each category, a one-to-one mapping between barriers and solutions is developed. The framework is specifically designed with the objective of offering actionable and practical advice to executives who face these challenges in their organizations. The paper provides a unique theoretical contribution by synthesizing findings from several academic disciplines with concrete examples from the pharmaceutical industry.

    NASA's Earth Right Now communication team kicked off an ambitious multimedia campaign in March 2016 to tell the stories of eight major field campaigns studying regions of critical change from the land, sea and air. Earth Expeditions focused on the human side of science, with live reporting from the field, behind-the-scenes images and videos, and extended storytelling over a six-month period. We reported from Greenland to Namibia, from the eastern United States to the South Pacific. Expedition scientists explored ice sheets, air quality, coral reefs, boreal forests, marine ecosystems and greenhouse gases. All the while the campaign communications team was generating everything from blog posts and social media shareables, to Facebook Live events and a NASA TV series. We also participated in community outreach events and pursued traditional media opportunities. A massive undertaking, we will share lessons learned, best practices for social media and some of our favorite moments when science communication touched our audience's lives.

    An important part of the ARGONA project is the testing and application of novel participation and dialogue approaches. The Czech Republic is one of the countries where these approaches will be applied and tested. The ways in this is being done include a series of events involving different stakeholders such as a focused science shop, a consensus panel and an interaction panel. In the framework of these activities in the Czech Republic the focused science shop was held on March 12, 2008 in the Nuclear Research Institute (NRI) in Rez, and addressed the theme: 'Radioactive waste management and radiation risk in comparison with other hazardous waste and risks'. The main goal of this focused science shop was to increase awareness amongst the public of actual and potential effects of radioactive and toxic wastes and to prioritise questions/uncertainties that people might have in this field. The following topics were discussed: - Differences in the general perception of nuclear waste in comparison with other toxic wastes; - General public awareness of the issue of nuclear waste management and other toxic wastes management; - Management and ultimate disposal of radioactive waste and other toxic waste in terms of the technology employed; - NIMBY effect. A broader audience was selected with a suitable mixture of specialists and interested technical and non-technical peers including representatives from NRI, universities, Ministry of Industry and Trade, Ministry of the Environment, State Office for Nuclear Safety and Radioactive Waste Repository Authority, representatives of municipalities and NGOs, and waste producers such as CEZ plc etc. In the Czech Republic there is a general unwillingness by the public to actively participate in the NWM decision-making process. Therefore, despite all the efforts made by the project team, not all invited stakeholders attended the meeting. Despite this, the meeting was very positively received by those who did attend and indicates the

    In this dialogue with Monica Ridgeway and Randy Yerrick's Whose banner are we waving?: exploring STEM partnerships for marginalized urban youth, I engage the critical race theory (CRT) tenet of interest convergence. I first expand Derrick Bell's (1980) initial statement of interest convergence with subsequent scholarly work in this area. I then explore ways CRT in general and interest convergence specifically have been applied in the field of education. Using this framing, I examine how interest convergence may be shed new insights into Monica Ridgeway and Randy Yerrick's study. For example, the tenet of interest convergence is used to frame why it was beneficial for the White artist, Jacob, and the Achievement Scholars to collaborate in the service-learning mural. Then the idea of interest divergence is brought into explore the ways in which Jacob benefitted from his participation in the service learning project while the Achievement Scholars were left with an unfinished project which they had to problem solve. To conclude, I provide future directions for the application of interest convergence and divergence to issues facing science education.

  13. Symbolic Interaction and Applied Social Research: A FOCUS ON TRANSLATIONAL SCIENCE RESEARCH1.

    Kotarba, Joseph A

    2014-08-01

    In symbolic interaction, a traditional yet unfortunate and unnecessary distinction has been made between basic and applied research. The argument has been made that basic research is intended to generate new knowledge, whereas applied research is intended to apply knowledge to the solution of practical (social and organizational) problems. I will argue that the distinction between basic and applied research in symbolic interaction is outdated and dysfunctional. The masters of symbolic interactionist thought have left us a proud legacy of shaping their scholarly thinking and inquiry in response to and in light of practical issues of the day (e.g., Znaniecki, and Blumer). Current interactionist work continues this tradition in topical areas such as social justice studies. Applied research, especially in term of evaluation and needs assessment studies, can be designed to serve both basic and applied goals. Symbolic interaction provides three great resources to do this. The first is its orientation to dynamic sensitizing concepts that direct research and ask questions instead of supplying a priori and often impractical answers. The second is its orientation to qualitative methods, and appreciation for the logic of grounded theory. The third is interactionism's overall holistic approach to interfacing with the everyday life world. The primary illustrative case here is the qualitative component of the evaluation of an NIH-funded, translational medical research program. The qualitative component has provided interactionist-inspired insights into translational research, such as examining cultural change in medical research in terms of changes in the form and content of formal and informal discourse among scientists; delineating the impact of significant symbols such as "my lab" on the social organization of science; and appreciating the essence of the self-concept "scientist" on the increasingly bureaucratic and administrative identities of medical researchers.

    2005-09-01

    Full Text Available In this paper I focus on a distinctive kind of sociological ethnography which is particularly, though not exclusively, adopted in applied research. It has been proposed that this branch of ethno­graphy be referred to as focused ethnography. Focused ethnography shall be delineated within the context of other common conceptions of what may be called conventional ethnography. However, rather than being opposed to it, focused ethno­graphy is rather complementary to conventional ethnography, particularly in fields that are charac­teristic of socially and functionally differentiated contemporary society. The paper outlines the back­ground as well as the major methodological features of focused ethnography, such as short-term field visits, data intensity and time intensity, so as to provide a background for future studies in this area.

    2016-12-01

    In order to better communicate relevant scientific knowledge to policy- and decision makers, Stockholm University and the Baltic Sea 2020 Foundation partnered to create Baltic Eye in 2014. Seven scientists and two communicators constitute the core team of this initiative. The team integrates communications with scientific analysis and synthesis of Baltic Sea environmental issues. In the past year, the team has focused on two main issues: fisheries management and microplastics. Baltic Sea cod stocks are in poor condition, with large numbers of small individuals. Baltic Eye recommended improvements to the European Union's multiannual fisheries plan to better align with ecosystem-based management principles: prioritization of cod stock recovery, greater consideration of natural variability of temperature and salinity (which affects cod spawning success), and inclusion of mechanisms to adjust quotas in the event of major environmental changes. Communications included policy briefs and debate articles targeted to the European Parliament, national government ministries, and non-governmental organizations. Every year, up to 40 tons of microplastics from personal care products are released in the Baltic Sea catchment. Baltic Eye raised awareness of the issue and made recommended ways to reduce microplastic emissions. Communications included a public presentation to journalists, politicians, and representatives of Swedish government ministries. A policy brief was provided Heads of Delegates of the Helsinki Commission (for protrection of the Baltic Sea environment) in advance of a meeting to develop a plan of action for marine litter. Researchers were interviewed for radio, TV, and print media in Sweden, Finland, and Germany. Next steps are to engage with multinational manufacturers about plans to voluntarily phase out microplastics in personal care products.

    Pujana, I.; Stern, R. J.; Ledbetter, C. E.

    2004-12-01

    With NSF-CCLI funding, we have developed, taught, and evaluated a new lower-division science course for non-majors, entitled "Geography, Resources, and Environment of Hispanic America" (GRELA). This is an adaptation of a similar course, "Geology and Development of Modern Africa" developed by Barbara Tewksbury (Hamilton College), to attract African American students to science by highlighting cultural ties with their ancestral lands. We think that a similar approach focusing on Latin America may attract Hispanic undergraduates, at the same time that it increases awareness among non-Hispanic students about challenges facing our neighbors to the south. GRELA is an interdisciplinary exploration of how the physical and biological environment of Mexico, Central America, and South America have influenced the people who live there. The course consists of 20 lectures and requires the student to present a report partnering with correspondents in Latin American universities. GRELA begins with an overview of Latin American physical and cultural geography and geologic evolution followed by a series of modules that relate the natural resources and environment of Latin America to the history, economy, and culture of the region. This is followed by an exploration of pre-Columbian cultures. The use of metals by pre-Columbian, colonial, and modern cultures is presented next. We then discuss hydrocarbon resources, geothermal energy, and natural hazards of volcanoes and earthquakes. The last half of the course focuses on Earth System Science themes, including El Nino, glaciers, the Amazon river and rainforest, and coral reefs. The final presentation concerns population growth and water resources along the US-Mexico border. Grades are based on two midterms, one final, and a project which requires that groups of students communicate with scientists in Latin America to explore some aspect of geography, natural resources, or the environment of a Latin American region of common interest

  18. The impact of a Latino outreach project on science museums: A program evaluation focused on institutional change

    Castaneda, Mario E.

    The purpose of this program evaluation was to determine the impact of the Community Science Festivals Project on the science museums that participated. This project, also known as Celebra la Ciencia (CLC), was a federally funded effort to engage the Latino communities throughout the United States in activities promoting appreciation of the importance of science education. The festivals brought together various educational, community, and scientific organizations that collaborated in producing community-hosted interactive educational events to which students and their families were invited. The evaluation takes the form of a qualitative study based on interviews of key individuals at 1 museum in each of the 5 festival cities. The evaluation focuses on the museums' changes in: (a) their view of their roles as involving the Latino population in their service area, (b) publicity efforts aimed at the Latino population, (c) outreach toward the Latino population, and (d) accommodation of Latinos within the museums. The results for each site are listed separately then are discussed jointly. Implications for practice include the following: (a) intensive and long-term programming, as opposed to one-time events, are likely more effective for creating direct impact on student achievement, although the festivals had many positive effects; (b) funding for smaller organizations (or individual departments within larger organization) seemed to have a more observable impact, enabling them to create Latino-oriented advertising, outreach, and accommodations that would not have been possible otherwise; and (c) Spanish-language media was an effective advertising tool, especially radio, but use of public service announcements should be monitored to ensure that they are aired at times that are effective for reaching the target audience. Recommendations for future studies are made.

A special teacher strand focused on leadership development supporting teachers to become effective change agents in their classrooms and schools, and developing strong teacher communities.

  20. Can a Three-Day Training Focusing on the Nature of Science and Science Practices as They Relate to Mind in the Making Make a Difference in Preschool Teachers' Self-Efficacy Engaging in Science Education?

    Science.gov (United States)

    Meacham, Colleen

    As technology and our world understanding develop, we will need citizens who are able to ask and answer questions that have not been thought of yet. Currently, high school and college graduates entering the workforce demonstrate a gap in their ability to develop unique solutions and fill the current technology-driven jobs. To address this gap, science needs to be prioritized early in children's lives. The focus of this research was to analyze a science training program that would help pre-school teachers better understand Mind in the Making life skills, the nature of science, science practices, and improve their self-efficacy integrating science education into their classrooms and curriculum. Seventy-one teachers enrolled in two three-day, professional development trainings that were conducted over three, five-hour sessions approximately one month apart... During that training the teachers learned hands-on activities for young children that introduced life and physical science content. They were also given the task of developing and implementing a science-based lesson for their students and then analyzing it with other participants. The information from the lesson plans was collected for analysis. After the last training the teachers were given a pre/post retrospective survey to measure effective outcomes. The results from the lesson plans and surveys indicate that the trainings helped improve the teachers' understanding of Mind in the Making, the nature of science, and science practices. The results also show that the teachers felt more comfortable integrating science education into their classrooms and curriculum.

    Hard exclusive processes in high energy electron proton scattering offer the opportunity to get access to a new generation of parton distributions, the so-called generalized parton distributions (GPDs). This functions provide more detailed informations about the structure of the nucleon than the usual PDFs obtained from DIS. In this work we present a detailed analysis of exclusive processes, especially of hard exclusive meson production. We investigated the influence of exclusive produced mesons on the semi-inclusive production of mesons at fixed target experiments like HERMES. Further we give a detailed analysis of higher order corrections (NLO) for the exclusive production of mesons in a very broad range of kinematics. (orig.)

Observes the International Year of the Astronomy 2009 [IYA 2009] as one of the greatest experiences STS worldwide, causing unprecedented integration between science, technology and humanities, with positive impacts in many sectors of society and are still worthy of study, specially in Brazil due to the implementation of the International Year of Astronomy, Brazil 2009 [IYABrazil-2009}. Astronomy is also investigated in the area of Education, based mainly on theoretical aspects of educational socio-interacionist of Lev Semenovich Vygotsky (Vygotsky, 1991, 2008 and 2012, p. 103-117) and socio-historical cultural of Paulo Reglus Neves Freire (1979, 1982 and 1996), but when necessary and still keeping the field of constructivism, properly taking advantage of the interactionism and transdisciplinarity of Jean William Fritz Piaget (1983). Concerning Distance Education [DE], it is noted significant growth at the graduate and postgraduate courses. New challenges arise, with the establishment of an increasingly accustomed to Information and Communication Technologies [ICT] and the teaching methodologies to be used and developed, with Astronomy becoming an important instrument in the teaching-learning process associated technologies. Using the methodology of action research, we proceeded with a case study involving 26 students of the discipline of Astronomy Topics applied to Education, between November 1 and December 17, 2012, of the postgraduation courses in Distance Education at the Universidade Cruzeiro do Sul [Southern Cross University]. The results obtained permit statistical surveys therefore quantitative, but also qualitative information about the teaching-learning Astronomy by DE.

    2014-11-01

    Early science instruction is important in order to lay a firm basis for learning scientific concepts and scientific thinking. In addition, young children enjoy science. However, science plays only a minor role in the kindergarten curriculum. It has been reported that teachers feel they need to prioritize language and literacy practices over science. In this paper, we investigate whether science lessons might be integrated with learning the language functional for school: academic language. The occurrence of scientific reasoning and sophisticated vocabulary in brief science lessons with 5-year-olds is evaluated. The aim of the study was twofold: first, to explore the nature of kindergarten science discourse without any researcher directions (pre-intervention observation). Second, in a randomized control trial, we evaluated the effect on science discourse of a brief teacher training session focused on academic language awareness. The science lessons focussed on air pressure and mirror reflection. Analyses showed that teachers from the intervention group increased their use of scientific reasoning and of domain-specific academic words in their science discourse, compared to the control group. For the use of general academic words and for lexical diversity, the effect was task-specific: these dependent measures only increased during the air pressure task. Implications of the study include the need to increase teachers' awareness of possibilities to combine early science instruction and academic language learning.

An exclusive dealing agreement is a contract between a buyer and a seller where the buyer commits to buy a good exclusively from the seller. One main concern of the literature is to explain how an incumbent seller is able to persuade the buyers to sign an exclusive dealing agreement that deters the entry of a more efficient rival seller. We propose a new explanation when the buyers are downstream ...

  13. Further Democratizing Latin America: Broadening Access to Higher Education and Promoting Science Policies Focused on the Advanced Training of Human Resources

    Directory of Open Access Journals (Sweden)

    Manuel Heitor

    2014-08-01

    Full Text Available We focus this paper on the conditions to build reliable science, technology and higher education systems in Latin America, based on international comparative studies, fieldwork and interviews conducted over the last three years. The analysis shows that science can have a major role in furthering the democratization of society through public policies that foster opportunities to access knowledge and the advanced training of human resources. Broadening the social basis for higher education promotes the qualification of the labour force and contributes to social and economic development. The need to guarantee higher education diversity, strengthening scientific institutions and investing in a strong science base, is deemed as critical, but goes far beyond policies centred on innovation and industry-science relationships. It requires adequate training and attraction of skilled people, as well as the social promotion of a scientific and technological culture.

    2007-05-01

    As minorities are predicted to comprise at least 33% of the US population by the year 2010, their representation in the STEM fields, including the ocean sciences, is still poorly established. In order to advance the goal of better decision making, the Ocean Sciences community must achieve greater levels of diversity in membership. To achieve this objective of greater diversity in the sciences, the Minorities Striving and Pursuing Higher Degrees of Success in Earth System Science® Professional Development Program (MS PHD'S PDP), which was launched in 2003, is supported via grants from NASA's Office of Earth Science, and NSF's Directorate for Geosciences. The MS PHD'S PDP is designed to provide professional and mentoring experiences that facilitate the advancement of minorities committed to achieving outstanding Earth System Science careers. The MS PHD'S PDP is structured in three phases, connected by engagement in a virtual community, continuous peer and mentor to mentee interactions, and the professional support necessary for ensuring the educational success of the student participants. Since the pilot program in 2003, the MSPHD'S PDP, housed at the University of South Florida's College of Marine Science, has produced 4 cohorts of students. Seventy-five have completed the program; of those 6 have earned their doctoral degrees. Of the 45 current participants 10 are graduate students in Marine Science and 15 are still undergraduates, the remaining 10 participants are graduate students in other STEM fields. Since the implementation of the MSPHD'S PDP a total of 87 students and 33 scientist mentors have become part of the MSPHD'S virtual community, helping to improve the learning environment for current and future participants as well as build a community of minority students that encourages each other to pursue their academic degrees.

    Formal support for undergraduates to participate in marine/ocean science research at Savannah State University (SSU), a historically-Black unit of the University System of Georgia, began in 1989 with funding from the National Science Foundation for an unsolicited proposal (OCE-8919102, 34,935). Today SSU, which has offered B.S degrees since 1979 and M.S. degrees since 2001 in Marine Sciences, is making major contributions nationally to demographic diversity in ocean sciences. 33% of Master's degrees in marine/ocean sciences earned by African Americans in the U.S. from 2004-2007 were earned at SSU. 10% of African American Master's and Doctoral students in marine/ ocean sciences in 2007 were either enrolled in the Master's program at SSU or were former SSU students enrolled in Doctoral programs elsewhere. Collaborative REU programs that focus on early (freshman and sophomore) undergraduate students have been a consistent and vital part of that success. In the most recent iteration of our summer REU program we used six of the best practices outlined in the literature to increase success and retention of underrepresented minority students in STEM fields: early intervention, strong mentoring, research experience, career counseling, financial support, workshops and seminars. The early intervention with strong mentoring has proven successful in several metrics: retention in STEM majors (96%), progression to graduate school (50%), and continuation to later research experiences (75%). Research mentors include faculty at staff at SSU, the Skidaway Institute of Oceanography, Gray's Reef National Marine Sanctuary and Georgia Tech-Savannah. Formal collaborative and cooperative agreements, externally-funded grants, and contracts in support of student research training have proven to be critical in providing resources for growth and improvement marine science curricular options at the University. Since 1981 the program has had four formal partnerships and 36 funded grant awards

    Ellwood, Robin B.

    This research investigated how student social interactions within two approaches to an inquiry-based science curriculum could be related to student motivation and achievement outcomes. This qualitative case study consisted of two cases, Off-Campus and On-Campus, and used ethnographic techniques of participant observation. Research participants included eight eighth grade girls, aged thirteen to fourteen years old. Data sources included formal and informal participant interviews, participant journal reflections, curriculum artifacts including quizzes, worksheets, and student-generated research posters, digital video and audio recordings, photographs, and researcher field notes. Data were transcribed verbatim and coded, then collapsed into emergent themes using NVIVO 9. The results of this research illustrate how setting conditions that promote focused concentration and communicative interactions can be positively related to student motivation and achievement outcomes in inquiry-based science. Participants in the Off-Campus case experienced more frequent states of focused concentration and out performed their peers in the On-Campus case on forty-six percent of classroom assignments. Off-Campus participants also designed and implemented a more cognitively complex research project, provided more in-depth analyses of their research results, and expanded their perceptions of what it means to act like a scientist to a greater extent than participants in the On-Campus case. These results can be understood in relation to Flow Theory. Student interactions that promoted the criteria necessary for initiating flow, which included having clearly defined goals, receiving immediate feedback, and maintaining a balance between challenges and skills, fostered enhanced student motivation and achievement outcomes. This research also illustrates the positive gains in motivation and achievement outcomes that emerge from student experiences with extended time in isolated areas referred to

    Building on growing interest in translational research, this paper provides an overview of a special issue of Administration and Policy in Mental Health and Mental Health Service Research, which is focused on the process of forging and sustaining partnerships to support child mental health prevention and services research. We propose that partnership-focused research is a subdiscipline of translational research which requires additional research to better refine the theoretical framework and the core principles that will guide future research and training efforts. We summarize some of the major themes across the eight original articles and three commentaries included in the special issue. By advancing the science of partnership-focused research we will be able to bridge the gap between child mental health prevention and services research and practice.

    Tartrazine is the best known and one of the most commonly used food additives. Food colorants are also used in many medications as well as foods. There has been conflicting evidence as to whether tartrazine causes exacerbations of asthma with some studies finding a positive association especially in individuals with cross-sensitivity to aspirin. To assess the overall effect of tartrazine (exclusion or challenge) in the management of asthma. A search was carried out using the Cochrane Airways Group specialised register. Bibliographies of each RCT was searched for additional papers. Authors of identified RCTs were contacted for further information for their trials and details of other studies. RCTs of oral administration of tartrazine (as a challenge) versus placebo or dietary avoidance of tartrazine versus normal diet were considered. Studies which focused upon allergic asthma, were also included. Studies of tartrazine exclusion for other allergic conditions such as hay fever, allergic rhinitis and eczema were only considered if the results for subjects with asthma were separately identified. Trials could be in either adults or children with asthma or allergic asthma (e.g. sensitivity to aspirin or food items known to contain tartrazine). Study quality was assessed and data abstracted by two reviewers independently. Outcomes were analysed using RevMan 4.1.1. Ninety abstracts were found, of which 18 were potentially relevant. Six met the inclusion criteria, but only three presented results in a format that permitted analysis and none could be combined in a meta-analysis. In none of the studies did tartrazine challenge or avoidance in diet significantly alter asthma outcomes. Due to the paucity of available evidence, it is not possible to provide firm conclusions as to the effects of tartrazine on asthma control. However, the six RCTs that could be included in this review all arrived at the same conclusion. Routine tartrazine exclusion may not benefit most patients

    Full Text Available Breastfeeding saves the lives of more than half a million infants in a year and cause strong emotional relationship between mother and child and their psychosocial development of personality. The aim of this study is to evaluate the effect of exclusive breastfeeding education on mothers' breastfeeding self-efficacy and stress. This experimental study with clinical trial has randomly selected three hospitals from hospitals affiliated to medical sciences universities of Tehran with intensive care units for premature infants, and 100 eligible nulliparous mothers were sampled during three months. Mothers are randomly classified into case and control groups (each group with 50 samples. The case group received breastfeeding education and educational booklet, but control group received no education. A month later, the samples reanswered to questionnaires. Data is collected through questionnaires and analyzed by descriptive and inferential statistics, T-test, paired-t, and Chi-Square tests. The results indicate that there is a significant difference between breastfeeding self-efficacy in pre and posteducational case group, so that education has significant effect on breastfeeding self-efficacy (t=10.7, p<0.01. Breastfeeding education especially in premature infants increases the mothers' breastfeeding self-efficacy, and thus the mothers with premature infants require special breastfeeding education.

    In this talk I concentrate on purely exclusive processes. In Sec. II form factors and exclusive decays of heavy quarkonium states will be discussed. In Sec. III elastic wide angle elastic scattering will be considered with emphasis placed on the energy dependence for a fixed angle. The x → 1 limit of structure functions is discussed in Sec. IV. This is a limit which matches on, in a rather complicated way, with transition form factors. In Sec. V the idea of intrinsic charm is considered, mostly from a conceptual viewpoint as to its definition and possible existence. In Sec. VI there is a brief discussion of calculations of matrix elements which occur in deeply inelastic scattering by use of a bag model. In Sec. VII wee parton cancellations and Sudakov corrections for μ-pair production are considered. Sec. VIII concerns soft particle production and the mutliplicity of hadrons in a jet. (orig./HSI)

    The aim of the current review was to examine the scope of studies published in the Science of Salt Weekly that contained a measure of self-reported knowledge, attitudes, and behavior (KAB) concerning salt. Specific objectives were to examine how KAB measures are used to evaluate salt reduction intervention studies, the questionnaires used, and whether any gender differences exist in self-reported KAB. Studies were reviewed from the commencement of Science of Salt Weekly, June 2013 to the end of August 2017. Seventy-five studies had relevant measures of KAB and were included in this review, 13 of these were salt-reduction intervention-evaluation studies, with the remainder (62) being descriptive KAB studies. The KAB questionnaires used were specific to the populations studied, without evidence of a best practice measure. 40% of studies used KAB alone as the primary outcome measure; the remaining studies used more quantitative measures of salt intake such as 24-hour urine. Only half of the descriptive studies showed KAB outcomes disaggregated by gender, and of those, 73% showed women had more favorable KAB related to salt. None of the salt intervention-evaluation studies showed disaggregated KAB data. Therefore, it is likely important that evaluation studies disaggregate, and are appropriately powered to disaggregate all outcomes by gender to address potential disparities. ©2018 Wiley Periodicals, Inc.

  12. The psychology of exclusivity

    Directory of Open Access Journals (Sweden)

    Troy Jollimore

    2008-02-01

    Full Text Available Friendship and romantic love are, by their very nature, exclusive relationships. This paper suggests that we can better understand the nature of the exclusivity in question by understanding what is wrong with the view of practical reasoning I call the Comprehensive Surveyor View. The CSV claims that practical reasoning, in order to be rational, must be a process of choosing the best available alternative from a perspective that is as detached and objective as possible. But this view, while it means to be neutral between various value-bearers, in fact incorporates a bias against those value-bearers that can only be appreciated from a perspective that is not detached—that can only be appreciated, for instance, by agents who bear long-term commitments to the values in question. In the realm of personal relationships, such commitments tend to give rise to the sort of exclusivity that characterizes friendship and romantic love; they prevent the agent from being impartial between her beloved’s needs, interests, etc., and those of other persons. In such contexts, I suggest, needs and claims of other persons may be silenced in much the way that, as John McDowell has suggested, the temptations of immorality are silenced for the virtuous agent.

    2017-11-01

    Full Text Available This paper locates the development of a science and technology museum within the history of the predominantly object-based Vienna Museum, which was founded early in the twentieth century. It portrays interactive engagement with young people in terms of its continuity with the aim of popularising science, which had been a founding principle of the museum. At the same time, this paper examines the way in which the rise of interactivity represented a radical shift from an emphasis on technology itself towards a focus upon scientific principles, a phenomenon which in turn had an influence upon enquiry-based learning.

    Kalenda, Peter

    Research on exhibit design over the past twenty years has started to identify many different methods to increase the learning that occurs in informal education environments. This study utilized relevant research on exhibit design to create and study the effectiveness of a mobile interactive exhibit at the Seneca Park Zoo that promotes socialization, engagement in science, and conservation-related practices among guests. This study will serve as one component of a major redesign project at the Seneca Park Zoo for their Rocky Coasts exhibit. This action research study targeted the following question, "How can interactive exhibits be designed to promote socialization, engagement in science, and real-world conservation-related practices (RCPs) among zoo guests?" Specific research questions included: 1. In what ways did guests engage with the exhibit? 2. In what ways were guests impacted by the exhibit? a) What evidence exists, if any, of guests learning science content from the exhibit? b) What evidence exists, if any, of guests being emotionally affected by the exhibit? c) What evidence exists, if any, of guests changing their RCPs after visiting the exhibit? Data were collected through zoo guest surveys completed by zoo guests comparing multiple exhibits, interviews with guests before and after they used the prototype exhibit, observations and audio recordings of guests using the prototype exhibit, and follow-up phone interviews with guests who volunteered to participate. Data were analyzed collaboratively with members of the zoo's exhibit Redesign Team using grounded theory qualitative data analysis techniques to find patterns and trends among data. Initial findings from data analysis were used to develop shifts in the exhibit in order to increase visitor engagement and learning. This process continued for two full action research spirals, which resulted in three iterations of the prototype exhibit. The overall findings of this study highlight the ways in which

    Psychotropic drug prescribing is problematic and knowledge of factors affecting the initiation and maintenance of such prescribing is incomplete. Such knowledge could provide a basis for the design of interventions to change prescribing patterns for psychotropics. The aim of this study was to explore the views of general practitioners (GPs), GP interns, and heads of primary care units on factors affecting the prescribing of psychotropic drugs in primary care. We performed four focus group discussions in Gothenburg, Sweden, with a total of 21 participants (GPs, GP interns, and heads of primary care units). The focus group discussions were transcribed verbatim and analyzed using manifest content analysis. Three different themes emerged from the focus group discussions. The first theme Seeking care for symptoms, reflects the participants' understanding of why patients approach primary care and comprised categories such as knowledge, attitudes, and society and the media. The second theme, Lacking a framework, resources, and treatment alternatives, which reflects the conditions for the physician-patient interaction, comprised categories such as economy and resources, technology, and organizational aspects. The third theme, Restricting or maintaining prescriptions, with the subthemes Individual factors and External influences, reflects the physicians' internal decision making and comprised categories such as emotions, knowledge, and pharmaceutical industry. The results of the present study indicate that a variety of factors may affect the prescribing of psychotropic medications in primary care. Many factors were related to characteristics of the patient, the physician or their interaction, rather than the patients' medical needs per se. The results may be useful for interventions to improve psychotropic prescribing in primary care.

    In this study a group of experts and clinical radiological technologists were surveyed to evaluate the clinical importance of current subjects in the radiological sciences. For the data collection and analysis, an open-ended questionnaire was distributed to the group of experts, and a multiple choice questionnaire was distributed to radiological technologists. Subjects were classified into 9 groups for analysis of the importance of subjects, and in regard to the questionnaire design for measurement of variables, departments and type of hospital were set up as independent variables, and the 9 groups of subjects were set up as dependent variables. As a result, clinical radiological technologists perceived Diagnostic Imaging Technology and practical courses, including general radiography, CT and MRI, as the most clinically necessary subjects, and the group of experts placed most weight on basic courses for the major. The result of this study suggests that the curriculum should be revised in a way that combines theory and practice in order to foster radiological technologists capable of adapting to the rapidly changing healthcare environment.

  18. Exclusion and authorization

    Cooper, J.R.

    'Everyone in the world is exposed to radiation from natural and artificial sources. Any realistic system of radiological protection must have a clearly defined scope if it is not to apply to the whole of mankind's activities'. This quote, from ICRP Publication 60 (ICRP, 1991), remains apposite. The main tool for defining scope is the concept of exclusion: situations, sources or exposures that are excluded from the system of radiological protection are, to all intents and purposes, ignored. Sources and exposures that are not excluded are within the scope of the system of protection and by inference within regulatory systems implementing ICRP recommendations. These sources and exposures should be subject to appropriate authorization by the relevant regulatory authority. In order to avoid excessive regulatory procedures, however, provisions should be made for granting an exemption in cases where it is clear that regulatory provisions are unnecessary. Exemption is a regulatory tool intended to facilitate efficient use of regulatory resources. Nevertheless, the regulatory act of granting exemptions is, in itself, a form of authorization and the material or situation so exempted remains within the regulatory system. This distinction between exclusion and exemption is an important one. Historically, the concept of exclusion has been applied to sources or exposures that are essentially unamenable to control because of their widespread nature. The usually quoted examples are cosmic radiation at ground level and 40 K in the body. Clearly, many exposures from natural sources could fall into this category. The challenges are firstly to establish a sound basis for deciding which should be excluded and which should be controlled, and secondly to see if the concept could or should be applied to artificial sources and exposures. These two questions are the subject of this paper. (author)

My definition in this chapter contributed to the shorter definition of bullying in the Introduction (see page XX), but it is more fully developed here in relation to the types of mechanisms and processes involved.

    Full Text Available Social exclusion is a process whereby certain individuals are pushed to the edge of society and prevented from participating fully by virtue of their poverty, or lack of basic competencies and lifelong learning opportunities or as a result of discrimination. This distances them from job, income and education opportunities as well as social and community networks and activities. Quality education (conditions and access/accessibility/availability is one of the factors that significantly influence the reduced social exclusion. In other words, education has is key role key role in ensuring social inclusion (equal opportunities and active social participation. At the same time, education and lifelong learning is established as the basis for achieving the goals of sustainable economic development (economy based on knowledge and to achieve social cohesion. Quality education is a prerequisite for progress, development and well-being of the community. Conditions and accessibility to education have become priorities of national reforms in most European countries. The subject of this paper is the educational structure of population of Serbia and the accessibility of education. The analysis covers the educational structure with regard to age, gender and type of settlement (city and other/villages settlements.

    Crowdfunding involves raising money from large groups of individuals, often through the use of websites dedicated to this purpose. Crowdfunding campaigns aimed at raising money to pay for expenses related to receiving medical treatment are receiving increased media attention and there is evidence that medical crowdfunding websites are heavily used. Nonetheless, virtually no scholarly attention has been paid to these medical crowdfunding campaigns and there is no systematic evidence about how widely they are used and for what reasons, and what effects they have on the provision of medical care and individuals' relationships to their health systems. Ethical concerns have been raised in relation to these campaigns, focusing on issues for campaigners and donors such as exposure to fraudulent campaigns, loss of privacy, and fairness in how medical crowdfunding funds are distributed. Medical crowdfunding websites themselves have not been systematically studied, despite their significant influence on how these campaigns are developed and promoted. In this paper, we identify three very broad and pressing ethical questions regarding medical crowdfunding for social scientists to address and offer some preliminary insights into key issues informing future answers to each: Who benefits the most from medical crowdfunding and how does medical crowdfunding affect access to medical care; How does medical crowdfunding affect our understanding of the causes of inadequate access to medical care; and How are campaigner and donor privacy affected by website design? Our observations indicate the need for increased scholarly attention to the ethical and practical effects of medical crowdfunding for campaigners, recipients, donors, and the health system as a whole.

    The University of Washington is adapting a popular UW Atmospheric Sciences course on Climate and Climate Change for the high school environment. In the process, a STEM-focused teaching and learning community has formed. With the support of NASA Global Climate Change Education 20 teachers have participated in an evolving professional development program that brings those actively engaged in research together with high school teachers passionate about bringing a formal climate science course into the high school. Over a period of several months participating teachers work through the UW course homework and delve deeply into specific subject areas. Then, during a week-long summer institute, scientists bring their particular expertise (e.g. radiation, modeling) to the high school teachers through lectures or labs. Together they identify existing lectures, textbook material and peer-reviewed resources and labs available through the internet that can be used to effectively teach the UW material to the high school students. Through this process the scientists learn how to develop teaching materials around their area of expertise, teachers engage deeply in the subject matter, and both the university and high school teachers are armed with the tools to effectively teach a STEM-focused introductory course in climate science. To date 12 new hands-on modules have been completed or are under development, exploring ice-cores, isotopes, historical temperature trends, energy balance, climate models, and more. Two modules have been tested in the classroom and are ready for peer-review through well-respected national resources such as CLEAN or the National Earth Science Teachers Association; three others are complete and will be implemented in a high school classroom this year, and the remainder under various stages of development. The UWHS ATMS 211 course was piloted in two APES (Advanced Placement Environmental Science classrooms) in Washington State in 2011/2012. The high school

Further study is required for comparative analysis of the factors impacting on the number of papers and citations, which is the criteria for quality evaluation of papers, in other area than the Nuclear Energy and Engineering to which this study was limited. As the media for research process and results, papers play an important role in the evaluation of research projects. While the traditional methods for evaluation of research results have been focused on quantity aspects, the implication of quality aspect is increasingly recognized. Most national labs have begun to shift from quantity to quality in their criteria for overall evaluation of research results. It is therefore desired to maximize the quality level of the research papers for which the trends in citation as quality indicator could be analyzed as well as the quantity aspect. This paper looks at the trends in the number of citation and papers as the indicators of quality and quantify, as drawn from Scopus Data Base. It also suggest top 5 Science Citation Index(Expanded) journals in terms of increase rate in both number of papers and citations. The purpose is to compare them with top 20 Science Citation Index(Expanded) journals in which Korea Atomic Energy Research researchers have published their papers in the past 10 years from 2005 to 2014 were submitted. This paper looked at the trends in the number of papers and citations as an indicator of quality of the research papers in the area of Nuclear Energy and Engineering which is in fact a limitation to the key subject area, not covering the whole nuclear science and technology.

    The nature of science (NOS) has become a central goal of science education in many countries. This study refers to a developmental work research program, in which four fifth-grade elementary in-service teachers participated. It aimed to improve their understandings of NOS and their abilities to teach it effectively to their students. The 1-year-long, 2012-2013, program consisted of a series of activities to support teachers to develop their pedagogical content knowledge of NOS. In order to accomplish our goal, we enabled teacher-researchers to analyze their own discourse practices and to trace evidence of effective NOS teaching. Many studies indicate the importance of examining teachers' discussions about science in the classroom, since it is teachers' understanding of NOS reflected in these discussions that will have a vital impact on students' learning. Our proposal is based on the assumption that reflecting on the ways people form meanings enables us to examine and seek alternative ways to communicate aspects of NOS during science lessons. The analysis of discourse data, which has been carried out with the teacher-researchers' active participation, indicated that initially only a few aspects of NOS were implicitly incorporated in teacher-researchers' instruction. As the program evolved, all teacher-researchers presented more informed views on targeted NOS aspects. On the whole, our discourse-focused professional development program with its participatory, explicit, and reflective character indicated the importance of involving teacher-researchers in analyzing their own talk. It is this involvement that results in obtaining a valuable awareness of aspects concerning pedagogical content knowledge of NOS teaching.

    There is growing literature exploring the possibility of parallel retrieval of location memories, although this literature focuses primarily on the speed of retrieval with little attention to the accuracy of location memory recall. Baguley, Lansdale, Lines, and Parkin (2006) found that when a person has two or more memories for an object's location, their recall accuracy suggests that only one representation can be retrieved at a time (exclusivity). This finding is counterintuitive given evidence of non-exclusive recall in the wider memory literature. The current experiment explored the exclusivity effect further and aimed to promote an alternative outcome (i.e., independence or superadditivity) by encouraging the participants to combine multiple representations of space at encoding or retrieval. This was encouraged by using anchor (points of reference) labels that could be combined to form a single strongly associated combination. It was hypothesised that the ability to combine the anchor labels would allow the two representations to be retrieved concurrently, generating higher levels of recall accuracy. The results demonstrate further support for the exclusivity hypothesis, showing no significant improvement in recall accuracy when there are multiple representations of a target object's location as compared to a single representation.

  9. Generalized exclusion and Hopf algebras

    Breastfeeding behaviour is explored in Kenya using data collected in the town of Eldoret, Kenya. This paper specifically examines duration of exclusive breastfeeding among young mothers below 20 years of age as compared to older cohorts. Additionally, focus is laid on the effect of first time motherhood and breastfeeding difficulties on exclusive breastfeeding. Results show that Eldoret mothers are aware of benefits of breastfeeding; nevertheless, the mean duration for exclusive breastfeeding in this sample is 2.4 months. Higher durations of exclusive breastfeeding are associated with increasing age and first time motherhood. Predictably, breastfeeding difficulties bear a negative association with exclusive breastfeeding. While HIV is transmissible through breastfeeding, breast milk remains a vital source of nourishment for infants in Sub-Saharan Africa. More research on mothering should examine the changing socio-economic milieu and its influence on women's infant feeding decisions

    This paper highlights the rationale for exclusive territories in a model of repeated interaction between competing supply chains. We show that with observable contracts exclusive territories have two countervailing effects on manufacturers' incentives to sustain tacit collusion. First, granting local monopolies to retailers distributing a given brand softens inter- and intrabrand competition in a one-shot game. Hence, punishment profits are larger, thereby rendering deviation more profitable....

    The definition of exclusion statistics, as given by Haldane, allows for a statistical interaction between distinguishable particles (multi-species statistics). The thermodynamic quantities for such statistics ca be evaluated exactly. The explicit expressions for the cluster coefficients are presented. Furthermore, single-species exclusion statistics is realized in one-dimensional integrable models. The interesting questions of generalizing this correspondence onto the higher-dimensional and the multi-species cases remain essentially open

    2017-12-01

    Science conducted in collaborative, cross-institutional research projects, requires active sharing of research ideas, data, documents and further information in a well-managed, controlled and structured manner. Thus, it is important to establish corresponding infrastructures and services for the scientists. Regular project meetings and joint field campaigns support the exchange of research ideas. Technical infrastructures facilitate storage, documentation, exchange and re-use of data as results of scientific output. Additionally, also publications, conference contributions, reports, pictures etc. should be managed. Both, knowledge and data sharing is essential to create synergies. Within the coordinated programme `Collaborative Research Center' (CRC), the German Research Foundation offers funding to establish research data management (RDM) infrastructures and services. CRCs are large-scale, interdisciplinary, multi-institutional, long-term (up to 12 years), university-based research institutions (up to 25 sub-projects). These CRCs address complex and scientifically challenging research questions. This poster presents the RDM services and infrastructures that have been established for two CRCs, both focusing on environmental sciences. Since 2007, a RDM support infrastructure and associated services have been set up for the CRC/Transregio 32 (CRC/TR32) `Patterns in Soil-Vegetation-Atmosphere-Systems: Monitoring, Modelling and Data Assimilation' (www.tr32.de). The experiences gained have been used to arrange RDM services for the CRC1211 `Earth - Evolution at the Dry Limit' (www.crc1211.de), funded since 2016. In both projects scientists from various disciplines collect heterogeneous data at field campaigns or by modelling approaches. To manage the scientific output, the TR32DB data repository (www.tr32db.de) has been designed and implemented for the CRC/TR32. This system was transferred and adapted to the CRC1211 needs (www.crc1211db.uni-koeln.de) in 2016. Both

    Today, 29 years after the Chernobyl accident, the Exclusion Zone still remains an areal unsealed radiation source of around 2600 km"2. It is not just a gigantic radioactive waste storage facility (the amount of radioactive waste accumulated within the Zone, except for the Shelter, is estimated at about 2.8 million m"3), but also a unique research and engineering platform for biologists, radiologists, chemists and physicists. Taking into account the amount of the radionuclides released during the accident, it becomes quite understood that the radiological environment in the Exclusion Zone is far from favorable. However, among the Exclusion Zone personnel who numbers 5000, there are female workers. The poster represents the results of the research performed among the female employees of the largest enterprise of the Exclusion Zone, “Chornobyl Spetskombinat”. The survey was performed with the view to knowing what makes women work in the most radioactively contaminated area in Europe, and what their role is, to revealing their fears and hopes, and to estimating the chances of the brave women of Chernobyl Exclusion Zone to succeed in their careers.

    Gegelashvili, M; Meca, A; Schwartz, S J

    2015-01-01

    In the present study we sought to clarify links between religious exclusivity, as form of intergroup favoritism, and indices of psychosocial functioning. The study of in group favoritism has generally been invoked within Social Identity Theory and related perspectives. However, there is a lack of literature regarding religious exclusivity from the standpoint of social identity. In particular, the ways in which religious exclusivity is linked with other dimensions of religious belief and practice, and with psychosocial functioning, among individuals from different religious backgrounds are not well understood. A sample of 8545 emerging-adult students from 30 U.S. universities completed special measures. Measure of religious exclusivity was developed and validated for this group. The results suggest that exclusivity appears as predictor for impaired psychosocial functioning, low self-esteem and low psychosocial well-being for individuals from organized faiths, as well as for those identifying as agnostic, atheist, or spiritual/nonreligious. These findings are discussed in terms of Social Identity Theory and Terror Management Theory (TMT).

Furthermore, single-species exclusion statistics is realized in one-dimensional integrable models of the Calogero-Sutherland type. The interesting questions of generalizing this correspondence to the higher-dimensional and the multispecies cases remain essentially open; however, our results provide some hints as to searches for the models in question

    Science.gov (United States)

    de Berg, Kevin C.

    2011-07-01

    This paper discusses the findings of a search for the intellectual tools used by Joseph Priestley (1733-1804) in his chemistry, education, and theology documents. Priestley's enquiring democratic view of knowledge was applicable in all three areas and constitutes a significant part of his lifework. Current epistemological issues in science education are examined from the point of view of the nature of theory and experiment as observed in Priestley's writings and as espoused in modern philosophy of science. Science and religious faith issues in the context of science education are examined from the point of view of one's understanding of sacred texts, and the suggestion is made that a Priestleyan model of "the liberty to think for oneself" and "to hold knowledge with humility and virtue" could prove helpful in dealing with the known divergent opinions in relation to science, education, and religion.

In addition, I propose a new definition of bullying. This new thinking technology reflects a shift in focus from individual characteristics...... to the social processes that may lead to bullying. The social approach theorises bullying as one of many reactions to particular kinds of social insecurity. The concepts I develop include the necessity of belonging, social exclusion anxiety and the production of contempt and dignity by both children and adults....... I also draw on Judith Butler’s concept of abjection. In the last part of the article, I employ Karen Barad’s theory of agential realism, focusing specifically on her concept of intraacting enacting forces.

  1. Social exclusion impairs distractor suppression but not target enhancement in selective attention.

    Social exclusion has been thought to weaken one's ability to exert inhibitory control. Existing studies have primarily focused on the relationship between exclusion and behavioral inhibition, and have reported that exclusion impairs behavioral inhibition. However, whether exclusion also affects selective attention, another important aspect of inhibitory control, remains unknown. Therefore, the current study aimed to explore whether social exclusion impairs selective attention, and to specifically examine its effect on two hypothesized mechanisms of selective attention: target enhancement and distractor suppression. The Cyberball game was used to manipulate social exclusion. Participants then performed a visual search task while event-related potentials were recorded. In the visual search task, target and salient distractor were either both presented laterally or one was presented on the vertical midline and the other laterally. Results showed that social exclusion differentially affected target and distractor processing. While exclusion impaired distractor suppression, reflected as smaller distractor-positivity (Pd) amplitudes for the exclusion group compared to the inclusion group, it did not affect target enhancement, reflected as similar target-negativity (Nt) amplitudes for both the exclusion and inclusion groups. Together, these results extend our understanding of the relationship between exclusion and inhibitory control, and suggest that social exclusion affects selective attention in a more complex manner than previously thought.

    Homelessness and poverty are extreme forms of social exclusion which extend beyond the lack of physical or material needs. The purpose of this study was to explore and expand the concept of social exclusion within the social determinants of health perspective - to understand how the social environment, health behaviours and health status are associated with material and social deprivation. Fundamental qualitative description with tones of focused ethnography. Participants who identified as hidden homeless described their everyday living conditions and how these everyday conditions were impacted and influenced by their social environments, coping/health behaviours and current health status. Research Ethics Board approval was granted and informed consents were obtained from 21 participants prior to the completion of individual interviews. Qualitative content analysis examined the descriptions of men and women experiencing hidden homelessness. Participants described the 'lack of quality social interactions and supports' and their 'daily struggles of street life'. They also shared the 'pain of addiction' and how coping strategies influenced health. Participants were hopeful that their insights would 'better the health of homeless people' by helping shape public policy and funding of community resources that would reduce barriers and improve overall health. Health professionals who understand health behaviours as coping mechanisms for poor quality social environments can provide more comprehensive and holistic care. The findings of this study can be used to support the importance of housing as a key factor in the health and well-being of people experiencing poverty, homelessness and social exclusion; and consequently, reinforces the need for a national housing strategy.

  3. Rationality alters the rank between peer punishment and social exclusion

    Science.gov (United States)

    Sui, Xiukai; Wu, Bin; Wang, Long

    2018-02-01

    Peer punishment and social exclusion are two ways to punish free-riders. Previous work usually focuses on how their presence, either peer punishment or social exclusion, shapes the evolution of cooperation. Little attention has been given to which of these two strategies is favored by natural selection when they are both present. Here we investigate how rationality alters the ranking of these two strategies. Under weak rationality, for compulsory public goods games, peer punishment has an evolutionary advantage over social exclusion if the efficiency of punishment or the cost of exclusion is high. Furthermore, this rank is preserved for voluntary public goods games where loners are involved. Under strong rationality, however, peer punishment cannot prevail over social exclusion for both compulsory and voluntary public goods games. This indicates that rationality greatly alters the rank between peer punishment and social exclusion. Moreover, we find that this ranking is sensitive to the rationality. Our work thus gives an insight into how different types of punishment evolve.

    In January 1994, the US Department of Energy Office of Environmental Management (DOE EM) formally introduced its new approach to managing DOE`s environmental research and technology development activities. The goal of the new approach is to conduct research and development in critical areas of interest to DOE, utilizing the best talent in the Department and in the national science community. To facilitate this solutions-oriented approach, the Office of Science and Technology (EM-50, formerly the Office of Technology Development) formed five Focus AReas to stimulate the required basic research, development, and demonstration efforts to seek new, innovative cleanup methods. In February 1995, EM-50 selected the DOE Morgantown Energy Technology Center (METC) to lead implementation of one of these Focus Areas: the Decontamination and Decommissioning (D & D) Focus Area.

  7. Without 'Focus'

    Directory of Open Access Journals (Sweden)

    Aldo Sevi

    2010-12-01

    Full Text Available It is widely accepted that a notion of 'focus', more or less as conceived of in Jackendoff (1972, must be incorporated into our theory of grammar, as a means of accounting for certain observed correlations between prosodic facts and semantic/pragmatic facts. In this paper, we put forth the somewhat radical idea that the time has come to give up this customary view, and eliminate 'focus' from our theory of grammar. We argue that such a move is both economical and fruitful.Research over the years has revealed that the correlations between prosody, 'focus', and the alleged semantic/pragmatic effects of focus are much less clear and systematic than we may have initially hoped. First we argue that this state of affairs detracts significantly from the utility of our notion of 'focus', to the point of calling into question the very motivation for including it in the grammar. Then we look at some of the central data, and show how they might be analyzed without recourse to a notion of 'focus'. We concentrate on (i the effect of pitch accent placement on discourse congruence, and (ii the choice of 'associate' for the so-called 'focus sensitive' adverb only. We argue that our focus-free approach to the data improves empirical coverage, and begins to reveal patterns that have previously been obscured by preconceptions about 'focus'.ReferencesBeaver, D. & Clark, B. 2008.

    Rew, Lynn; Thurman, Whitney; McDonald, Kari

    Sexual health and sexual rights are integral to nursing science but ignored in nursing publications. We searched Advances in Nursing Science for prevalence of these topics. Fifteen articles (1.3%) met our criteria. No nursing theories were used as frameworks, and few concrete suggestions were made for further theory development. Discussion of sociopolitical influences on sexual health and/or sexual rights was limited, mostly unrelated to health care. Information to influence nursing practice, theory development, further research, or policy across the life span, for both males and females, and for variant-gender individuals, was limited. We urge authors to contribute further to this field of discourse in nursing.

    Full Text Available Hoarding Disorder (HD was originally conceptualized as a subcategory of Obsessive Compulsive Disorder (OCD, and numerous studies have in fact focused exclusively on investigating the comorbidity between OCD and HD. Hoarding behavior can nevertheless also be found in other clinical populations and in particular in patients with eating disorders (ED, anxiety disorders (AD, major depression (MD, and psychotic disorders (PD. The current study was carried out with the aim of investigating, using a validated instrument such as the Saving Inventory-Revised (SI-R, the presence of HD symptoms in patients diagnosed with ED, AD, MD and PD. Hoarding symptomatology was also assessed in groups of self-identified hoarders (SIH and healthy controls. The results revealed that 22.5% of the ED patients exceeded the cut-off for the diagnosis of HD, followed by 7.7% of the patients with MD, 7.4% of the patients with AD, and 5.9% of the patients with PD. The patients with ED had significantly higher SI-R scores than the other groups in the Acquisition and Difficulty Discarding scales while the AD, MD, and PD patients were characterized exclusively by Difficulty Discarding. These data suggest to clinicians that hoarding symptoms should be assessed in other types of patients and especially in those affected by Bulimia and Binge eating.

    2017-07-01

    As the two leading markets for pharmaceutical and biotech companies, the USA and Europe offer incentives to stimulate drug innovation, including patent and regulatory exclusivities. These exclusivities extend periods during which companies can market their products free of generic or other competition and recoup their investment. Pharmaceutical and biotech companies should carefully assess the different types of exclusivities available when developing regulatory submissions, patent filing strategies. The authors have previously summarized the USA exclusivities in an earlier publication. This article focuses on European exclusivities. Due to space limitations, it focuses on small molecule drugs. Analogously to the format previously used, we have provided a cheat sheet of European exclusivities for small molecule drugs in Figure 1 .

To provide an impetus for research on the interactive nature of exclusion, we propose the Responsive Theory of Social Exclusion.

We propose that sources have three options: explicit rejection (clearly stating no, ostracism (ignoring, and ambiguous rejection (being unclear.

  20. Measuring social exclusion in healthcare settings: a scoping review.

    Science.gov (United States)

    O'Donnell, Patrick; O'Donovan, Diarmuid; Elmusharaf, Khalifa

    2018-02-02

    Social exclusion is a concept that has been widely debated in recent years; a particular focus of the discussion has been its significance in relation to health. The meanings of the phrase "social exclusion", and the closely associated term "social inclusion", are contested in the literature. Both of these concepts are important in relation to health and the area of primary healthcare in particular. Thus, several tools for the measurement of social exclusion or social inclusion status in health care settings have been developed. A scoping review of the peer-reviewed and grey literature was conducted to examine tools developed since 2000 that measure social exclusion or social inclusion. We focused on those measurement tools developed for use with individual patients in healthcare settings. Efforts were made to obtain a copy of each of the original tools, and all relevant background literature. All tools retrieved were compared in tables, and the specific domains that were included in each measure were tabulated. Twenty-two measurement tools were included in the final scoping review. The majority of these had been specifically developed for the measurement of social inclusion or social exclusion, but a small number were created for the measurement of other closely aligned concepts. The majority of the tools included were constructed for engaging with patients in mental health settings. The tools varied greatly in their design, the scoring systems and the ways they were administered. The domains covered by these tools varied widely and some of the tools were quite narrow in the areas of focus. A review of the definitions of both social inclusion and social exclusion also revealed the variations among the explanations of these complex concepts. There are several definitions of both social inclusion and social exclusion in use and they differ greatly in scope. While there are many tools that have been developed for measuring these concepts in healthcare settings, these

  5. `Teaching What I Learned': Exploring students' Earth and Space Science learning experiences in secondary school with a particular focus on their comprehension of the concept of `geologic time'

    Science.gov (United States)

    Yoon, Sae Yeol; Peate, David W.

    2015-06-01

    According to the national survey of science education, science educators in the USA currently face many challenges such as lack of qualified secondary Earth and Space Science (ESS) teachers. Less qualified teachers may have difficulty teaching ESS because of a lack of conceptual understanding, which leads to diminished confidence in content knowledge. More importantly, teachers' limited conceptual understanding of the core ideas automatically leads to a lack of pedagogical content knowledge. This mixed methods study aims to explore the ways in which current secondary schooling, especially the small numbers of highly qualified ESS teachers in the USA, might influence students' learning of the discipline. To gain a better understanding of the current conditions of ESS education in secondary schools, in the first phase, we qualitatively examined a sample middle and high school ESS textbook to explore how the big ideas of ESS, particularly geological time, are represented. In the second phase, we quantitatively analyzed the participating college students' conceptual understanding of geological time by comparing those who had said they had had secondary school ESS learning experience with those who did not. Additionally, college students' perceptions on learning and teaching ESS are discussed. Findings from both the qualitative and quantitative phases indicate participating students' ESS learning experience in their secondary schools seemed to have limited or little influence on their conceptual understandings of the discipline. We believe that these results reflect the current ESS education status, connected with the declining numbers of highly qualified ESS teachers in secondary schools.

  6. Teaching/learning styles, performance, and students' teaching evaluation in S/T/E/S-focused science teacher education: A quasiquantitative probe of a case study

    Science.gov (United States)

    Toller, Uri

    In response to the new needs for S/T/E/S-literate science teachers, an S/T/E/S-oriented ISMMC-IEE combination model of instruction was implemented in two specially designed undergraduate courses and one graduate course within college science teacher training programs. These three courses served as case studies for class-based, quasiquantitative pilot investigation aimed at gaining a deeper insight into some of the issues involved in the implementation in college of nontraditional, open-ended, problem-solving-oriented teaching strategies which are in dissonance with the cognitive or affective styles and functional paradigms of most students. This probe into the dissonance issue revealed that prospective teachers are capable of handling the new instructional model and do gain in their higher-level cognitive learning. However, undergraduates perceive these courses to be either difficult or not in accord with their needs, and their appreciation of the instructional techniques and style employed is different from that of graduate students accordingly. The current study suggests that although the ISMMC-IEE model is useful in S/T/E/S-oriented courses in science teacher training programs, special attention to the implementation stage is required to close the gap between students' and S/T/E/S educators' functional paradigms.

    2007-01-01

    We investigate electroproduction of pion pairs on the nucleon in the framework of QCD factorization for hard exclusive processes. We extend previous analyses by taking the hard-scattering coefficients at next-to-leading order in α s . The dynamics of the produced pion pair is described by two-pion distribution amplitudes, for which we perform a detailed theoretical and phenomenological analysis. In particular, we obtain constraints on these quantities by comparing our results with measurements of angular observables that are sensitive to the interference between two-pion production in the isoscalar and isovector channels.

    2018-01-01

    We introduce a rigorous approach to the many-body spectral theory of extended anyons, that is quantum particles confined to two dimensions that interact via attached magnetic fluxes of finite extent. Our main results are many-body magnetic Hardy inequalities and local exclusion principles for these particles, leading to estimates for the ground-state energy of the anyon gas over the full range of the parameters. This brings out further non-trivial aspects in the dependence on the anyonic statistics parameter, and also gives improvements in the ideal (non-extended) case.

  9. Grounded Theory Method: Sociology's Quest for Exclusive Items of Inquiry

    Directory of Open Access Journals (Sweden)

    Edward Tolhurst

    2012-09-01

    Full Text Available The genesis and development of grounded theory method (GTM is evaluated with reference to sociology's attempt to demarcate exclusive referents of inquiry. The links of objectivist GTM to positivistic terminology and to the natural scientific distinction from "common sense" are explored. It is then considered how the biological sciences have prompted reorientation towards constructivist GTM, underpinned by the metaphysics of social constructionism. GTM has been shaped by the endeavor to attain the sense of exactitude associated with positivism, whilst also seeking exclusive referents of inquiry that are distinct from the empirical realm of the natural sciences. This has generated complex research techniques underpinned by tortuous methodological debate: eschewing the perceived requirement to define and defend an academic niche could help to facilitate the development of a more useful and pragmatic orientation to qualitative social research.

  14. Implementation of exclusive truck facilities

    Energy Technology Data Exchange (ETDEWEB)

    Fekpe, E. [Battelle Memorial Inst., Columbus, OH (United States). Transportation Market Sector

    2007-07-01

    This paper discussed the issue of highway congestion, safety, and efficiency in freight movement on highways, with particular reference to the challenge of supporting increasing capacity demand from truck traffic. Innovative and practical solutions are needed to address the growing need for more efficient freight movement while maintaining acceptable levels of safety on highways. The concept of exclusive truck facilities (ETFs) is becoming an attractive option as a feasible strategy to help stabilize traffic flow, reduce congestion, improve safety, enhance transportation system management, improve access to freight facilities, and improve efficiency in freight movement along corridors of national importance. ETFs can either be truck only lanes or truckways. Passenger cars may not use ETFs. However, the use of ETFs could involve high costs of construction, maintenance, and acquisition of additional right of way. A cost-benefit analysis was performed for alternative ETF configurations under different traffic and site characteristics. A set of criteria was then proposed for identifying suitable locations for exclusive truck lanes. It was proposed that ETFs are economically feasible at locations with traffic volume of 100,000 vehicles per day or more and with a truck volume of at least 25 per cent of the traffic. In addition, the rate of truck-involved fatal crashes and level of service should be used to prioritize preliminary candidate locations that satisfy the traffic criteria. Consideration should also be given to the existence of freight terminals, ports, processing centers or regional distribution centres that are close to highways. 11 refs., 1 tab.

  15. Exclusive scattering off the deuteron

    2007-12-15

    Exclusive processes are a special class of processes giving insight into the inner structure of hadrons. In this thesis we consider two exclusive processes and compute their total cross sections as well as the beam charge and beam polarization asymmetries for different kinematical constraints. These calculations o er the opportunity to get access to the nonperturbative GPDs. Theoretically they can be described with the help of models. The rst process we investigate contains a GPD of the pion, which is basically unknown so far. We include different models and make predictions for observables that could in principle be measured at HERMES at DESY and CLAS at JLab. The second process we consider is electron-deuteron scattering in the kinematical range where the deuteron breaks up into a proton and a neutron. This can be used to investigate the neutron, which cannot be taken as a target due to its lifetime of approximately 15 minutes. For the calculation of the electron-deuteron cross section we implement models for the proton and neutron GPDs. Once there are experimental data available our calculations are ready for comparison.

  17. Focusing horn

    CERN Multimedia

    1980-01-01

    This was the first magnetic horn developed by Simon Van der Meer to collect antiprotons in the AD complex. It was used for the AA (antiproton accumulator). Making an antiproton beam took a lot of time and effort. Firstly, protons were accelerated to an energy of 26 GeV/c (protons at 26GeV/c, antiprotons at 3.6GeV/c) in the PS and ejected onto a metal target. From the spray of emerging particles, a magnetic horn picked out 3.6 GeV antiprotons for injection into the AA through a wide-aperture focusing quadrupole magnet. For a million protons hitting the target, just one antiproton was captured, 'cooled' and accumulated. It took 3 days to make a beam of 3 x 10^11 -, three hundred thousand million - antiprotons. The development of this technology was a key step to the functioning of CERN's Super Proton Synchrotron as a proton - antiproton collider.

    2014-01-01

    Full Text Available A preferential subscription right to shares is a subjective property right of a shareholder based on which he or she has a preferential right of subscription to shares from a new issue in proportion to the number of fully paid-in shares of that class he or she holds on the date of adoption of the decision on issuing of shares compared with the total number of shares of that class. However, this right of a shareholder can be completely or partially excluded, if formal and substantial requirements for such exclusion are met. This paper focuses primarily on analysis of formal requirements for exclusion envisaged by the Serbian Law on Companies with a brief review of EU law and comparative law. According to the Serbian Law on Companies, there are three formal requirements for exclusion of a preferential subscription right: 1. shares are issued through the offer for which there is no obligation to publish a prospectus; 2. there is a written proposal for exclusion from the Board of Directors, or of the Supervisory Board if a company has a two-tier management system; 3. the exclusion is based on a decision of the General Meeting of the Joint-stock company. With regards formal requirements, the paper concentrates on several weaknesses of the Serbian Law on Companies which considerably undermine the position of the so-called small shareholders.

  1. Longitudinal Study of Career Cluster Persistence from 8th Grade to 12th Grade with a Focus on the Science, Technology, Engineering, & Math Career Cluster

    Science.gov (United States)

    Wagner, Judson

    Today's technology driven global economy has put pressure on the American education system to produce more students who are prepared for careers in Science, Technology, Engineering, and Math (STEM). Adding to this pressure is the demand for a more diverse workforce that can stimulate the development of new ideas and innovation. This in turn requires more female and under represented minority groups to pursue future careers in STEM. Though STEM careers include many of the highest paid professionals, school systems are dealing with exceptionally high numbers of students, especially female and under represented minorities, who begin but do not persist to STEM degree completion. Using the Expectancy-Value Theory (EVT) framework that attributes student motivation to a combination of intrinsic, utility, and attainment values, this study analyzed readily available survey data to gauge students' career related values. These values were indirectly investigated through a longitudinal approach, spanning five years, on the predictive nature of 8 th grade survey-derived recommendations for students to pursue a future in a particular career cluster. Using logistic regression analysis, it was determined that this 8 th grade data, particularly in STEM, provides significantly high probabilities of a 12th grader's average grade, SAT-Math score, the math and science elective courses they take, and most importantly, interest in the same career cluster.

    1996-08-01

    To ensure research and development programs focus on the most pressing environmental restoration and waste management problems at the U.S. Department of Energy (DOE), the Assistant Secretary for the Office of Environmental Management (EM) established a working group in August 1993 to implement a new approach to research and technology development. As part of this new approach, EM developed a management structure and principles that led to the creation of specific Focus Areas. These organizations were designed to focus the scientific and technical talent throughout DOE and the national scientific community on the major environmental restoration and waste management problems facing DOE. The Focus Area approach provides the framework for intersite cooperation and leveraging of resources on common problems. After the original establishment of five major Focus Areas within the Office of Technology Development (EM-50, now called the Office of Science and Technology), the Nuclear Materials Stabilization Task Group (EM-66) followed the structure already in place in EM-50 and chartered the Plutonium Focus Area (PFA).

    Driven diffusive systems are often used as simple discrete models of collective transport phenomena in physics, biology or social sciences. Restricting attention to one-dimensional geometries, the asymmetric simple exclusion process (ASEP) plays a paradigmatic role to describe noise-activated driven motion of entities subject to an excluded volume interaction and many variants have been studied in recent years. While in the standard ASEP the noise is Poissonian and the process is therefore Markovian, in many applications the statistics of the activating noise has a non-standard distribution with possible memory effects resulting from internal degrees of freedom or external sources. This leads to temporal correlations and can significantly affect the shape of the current-density relation as has been studied recently for a number of scenarios. In this paper we report a general framework to derive the fundamental diagram of ASEPs driven by non-Poissonian noise by using effectively only two simple quantities, viz., the mean residual lifetime of the jump distribution and a suitably defined temporal correlation length. We corroborate our results by detailed numerical studies for various noise statistics under periodic boundary conditions and discuss how our approach can be applied to more general driven diffusive systems.

  7. Authentic Leadership, Research Integrity, and Institutions of Higher Learning: Why Focusing on Departmental Leadership is Critical for Preserving the Sanctity of Science

    Science.gov (United States)

    Echols, Katherine I.

    One of the most overlooked and complex problems that universities and colleges face nation-wide is how to reduce and eliminate research misconduct. Because of the confidential nature of allegations of research misconduct and the high rate of underreporting, administrators at scholarly institutions struggle with understanding the cause of such behavior. Without a clear picture of the prevalence of misconduct or the barriers to reporting, leaders at institutions of higher learning find themselves at a disadvantage when dealing with these problems. This uncertainty coupled with a growing regulatory emphasis from federal funding agencies, results in a reactionary approach while questionable practices go unchecked. In the early 2000s, federal funding agencies began requiring colleges and universities to provide training in the responsible conduct of research prior to receiving funding. The Responsible Conduct of Research (RCR) training covers research misconduct (falsification of data, fabricating data, and plagiarism) as well as other topics related to research misbehaviors (mentoring, peer review, data management, authorship, etc). This emphasis on training, while well intended, has not had a significant impact on faculty and student knowledge about misconduct. Authentic Leadership Theory is based on Aristotle's concept of authenticity and has gained attention over the last decade. It is comprised of four main components: Balanced processing, internalized moral perspective, relational transparency, and self-awareness. These types of leaders focus on moral standards and values and that is what guides his or her leadership. This study evaluates the impact authentic leaders have on shaping the ethical attitudes of faculty when they are placed in direct departmental supervisory positions. A survey of faculty from 15 Mississippi colleges and universities was conducted. Results indicate that the self-awareness and relational transparency constructs of authentic leadership

    Full Text Available One of the main consequences of the large Norwegian curriculum reform in 2006 is that teachers in all subjects are now responsible for focusing on the basic skills of reading, writing, oral, arithmetic and the use of digital tools. However, research following the implementation of the reform report a gap between curriculum intentions and classroom practice regarding basic skills. Hence the curriculum in science and four other subjects are now revised to clarify basic skills. This article describes some of the background for the revision, the revision process and some main changes in the revised curriculum.

    Our brain is sensitive to stress. Both acute and chronic stress cause cognitive deficits and induce chronic disorders such as drug addiction. In a June 2011 conference at Yale entitled "The Science of Stress: Focus on the Brain, Breaking Bad Habits, and Chronic Disease," Drs. Amy Arnsten and Sherry Mckee discussed the roles of prefrontal cortex in the treatment of stress impairments and addiction. Medications to strengthen the prefrontal function, such as prazosin and guanfacine, may reduce the harm of stress and help overcome smoking and alcohol abuse.

The main results are related to the effects created at the interaction of powerful pulses of different types of radiation (soft and hard X-rays, hot plasma and fast ion streams, neutrons, etc. generated in Dense Plasma Focus (DPF) facilities) with various materials including those that are counted as perspective ones for their use in future thermonuclear reactors. Besides we discuss phenomena observed at the irradiation of biological test objects. We examine possible applications of nanosecond powerful pulses of neutrons to the aims of nuclear medicine and for disclosure of hidden illegal objects. Special attention is devoted to discussions of a possibility to create extremely large and enormously diminutive DPF devices and probabilities of their use in energetics, medicine and modern electronics.

    Full Text Available The aim of this paper is critically examining assumptions underlying the Inclusive Education concept, arguing that this can only be effectively considered when understood in a broader context of social inclusion and exclusion. Methodologically, this article relies on international documents and bibliographic references about Inclusive Education, that have been chosen by systematize and characterize different social and educational inclusive practices, encouraging the elaboration of a general overview on this topic. The results of this analysis conclude that it is essential for Inclusive Education that educational institutions review their goals and reasons of social existence. In the concluding remarks it is argued that education is better understood as the act of encouraging and welcoming the efforts of individuals in their attempts to engage in social networking, which sustains life. This includes the acceptance of other reality interpretations and understanding that educational action cannot be restricted by the walls of institutions. It requires the participation of the whole community. Action perspectives likely to promote social inclusion and inclusive education are suggested.

  14. Perturbative QCD and exclusive processes

    International Nuclear Information System (INIS)

    Bennett, J.; Hawes, F.; Zhao, M.; Zyla, P.

    1991-01-01

    The authors discuss perturbation theory as applied to particle physics calculations. In particle physics one is generally interested in the scattering amplitude for a system going from some initial state to a final state. The intermediate state or states are unknown. To get the scattering amplitude it is necessary to sum the contributions from processes which pass through all possible intermediate states. Intermediate states involve the exchange of intermediate vector bosons between the particles, and with this interaction is associated a coupling constant α. Each additional boson exchange involves an additional contribution of α to the coupling. If α is less than 1, one can see that the relative contribution of higher order processes is less and less important as α falls. In QCD the gluons serve as the intermediate vector bosons exchanged by quarks and gluons, and the interaction constant is not really a constant, but depends upon the distance between the particles. At short distances the coupling is small, and one can assume perturbative expansions may converge rapidly. Exclusive scattering processes, as opposed to inclusive, are those in which all of the final state products are detected. The authors then discuss the application of perturbative QCD to the deuteron. The issues of chiral conservation and color transparancy are also discussed, in the scheme of large Q 2 interations, where perturbative QCD should be applicable

    Many studies have investigated how exclusion affects cognitive control and have reported inconsistent results. However, these studies usually treated cognitive control as a unitary concept, whereas it actually involved two main sub-processes: conflict detection and response implementation. Furthermore, existing studies have focused primarily on exclusion’s effects on conscious cognitive control, while recent studies have shown the existence of unconscious cognitive control. Therefore, the present study investigated whether and how exclusion affects the sub-processes underlying conscious and unconscious cognitive control differently. The Cyberball game was used to manipulate social exclusion and participants subsequently performed a masked Go/No-Go task during which event-related potentials were measured. For conscious cognitive control, excluded participants showed a larger N2 but smaller P3 effects than included participants, suggesting that excluded people invest more attention in conscious conflict detection, but less in conscious inhibition of impulsive responses. However, for unconscious cognitive control, excluded participants showed a smaller N2 but larger P3 effects than included participants, suggesting that excluded people invest less attention in unconscious conflict detection, but more in unconscious inhibition of impulsive responses. Together, these results suggest that exclusion causes people to rebalance attention allocation priorities for cognitive control according to a more flexible and adaptive strategy.

  2. Exclusive language: The tool to empower and create identity

    Directory of Open Access Journals (Sweden)

    Ananda Geyser-Fouche

    2016-03-01

    Full Text Available This article used some postmodern literary theories of philosophers such as Jean-Fran�ois Lyotard, Michel Foucault, Jacques Derrida and Julia Kristeva to scrutinise a selection of texts from the post-exilic period with regard to the exclusive language employed in these texts. Lyotard�s insights relate to and complement Foucault�s concept of �counter-memory�. Foucault also focuses on the network of discursive powers that operate behind texts and reproduce them, arguing that it is important to have a look from behind so as to see which voices were silenced by the specific powers behind texts. The author briefly looked at different post-exilic texts within identity-finding contexts, focusing especially on Chronicles and a few Qumran texts, to examine the way in which they used language to create identity and to empower the community in their different contexts. It is generally accepted that both the author(s of 1 & 2 Chronicles and the Qumran community used texts selectively, with their own nuances, omissions and additions. This study scrutinised the way the author(s of Chronicles and the Qumran community used documents selectively, focusing on the way in which they used exclusive language. It is clear that all communities used such language in certain circumstances to strengthen a certain group�s identity, to empower them and to legitimise this group�s conduct, behaviour and claims � and thereby exclude other groups.Intradisciplinary and/or interdisciplinary implications: Based on postmodern literary theories, this article compares the exclusive language used in Chronicles and in the texts of the Qumran community, pointing to the practice of creating identity and empowering through discourse. In conclusion, the article reflects on what is necessary in a South African context, post-1994, to be a truly democratic country.Keywords: Exclusive language; inclusive; Jean-Fran�ois Lyotard, Michel Foucault, Pierre Bourdieu; Derrida

  3. Science Communication in Teacher Personal Pronouns

    Oliveira, Alandeom W.

    2011-09-01

    In this study, I explore how personal pronouns used by elementary teachers during science inquiry discussions communicate science and frame teacher-student-science relations. A semiotic framework is adopted wherein teacher pronominal choices are viewed as symbolically expressing cognitive meanings (scientific thinking, forms of expression, and concepts) and indexically communicating social meanings (hidden messages about social and personal aspects of science-human agency, science membership, and gender). Through the construction of interactional maps and micro-ethnographic analysis of classroom video-recordings, I focus specifically on participant examples (oral descriptions of actual or hypothetical situations wherein the teacher presents herself and/or her students as characters to illustrate topics under discussion). This analysis revealed that the teacher use of the generalised you communicated to the students how to mean scientifically (i.e. to speak like a scientist), while I communicated scientific ways of thinking and reasoning. Furthermore, teacher pronouns communicated the social nature of science (NOS) (e.g. science as a human enterprise) as well as multiple teacher-student-science relational frames that were inclusive of some students (mainly boys) but excluded girls (i.e. positioned them as science outsiders). Exclusive use of he was taken as indicative of a gender bias. It is argued that science teachers should become more aware of the range of personal pronouns available for science instruction, their advantages and constraints for science discussions, their potential as instructional tools for humanising and personalising impersonal science curricula as well as the risk of 'NOS' miscommunication.

    2017-02-01

    Breastfeeding has many well-established health benefits for infants and mothers. There is greater risk reduction in health outcomes with exclusive breastfeeding (EBF). Our urban academic facility has had long-standing low EBF rates, serving a population with breastfeeding disparities. We sought to improve EBF rates through a Learning Collaborative model by participating in the Best Fed Beginnings project. Formal improvement science methods were used, including the development of a key driver diagram and plan-do-study-act cycles. Improvement activities followed the Ten Steps to Successful Breastfeeding. We demonstrated significant improvement in the median adherence to 2 process measures, rooming in and skin-to-skin after delivery. Subsequently, the proportion of infants exclusively breastfed at hospital discharge in our facility increased from 37% to 59%. We demonstrated an increase in sustained breastfeeding in a subset of patients at a postpartum follow-up visit. These improvements led to Baby-Friendly designation at our facility. This quality improvement initiative resulted in a higher number of infants exclusively breastfed in our patient population at "high risk not to breastfeed." Other hospitals can use these described methods and techniques to improve their EBF rates. Copyright © 2017 by the American Academy of Pediatrics.

  6. Reasons for Stopping Exclusive Breastfeeding Between Three and Six Months: A Qualitative Study.

    Science.gov (United States)

    Alianmoghaddam, Narges; Phibbs, Suzanne; Benn, Cheryl

    Scant published qualitative literature exists focusing on why exclusive breastfeeding rates decline between three and six months. This study aims to develop an understanding of why exclusive breastfeeding tails off so dramatically between three and six months after birth in New Zealand. A generic qualitative methodology was employed in this study and social constructionism selected as the main epistemological framework underpinning the research. This study was carried out between September 2013 and July 2014, involving face-to-face interviews with 30 women who were characterised as highly motivated to complete six months exclusive breastfeeding prior to the birth of their child. In order to gain an in-depth understanding of the research material, thematic analysis of the interview transcripts was completed using manual coding techniques. After thematic analysis of the data four key themes were identified: 1) The good employee/good mother dilemma. 2) Breastfeeding is lovely, but six months exclusively is demanding. 3) Exclusive breastfeeding recommendations should be individualised. 4) Introducing solids early as a cultural practice. Most studies have linked barriers to six months exclusive breastfeeding to difficulties within the mother-infant dyad, as well as negative maternal socioeconomic and socio-demographic characteristics. However, this study has shown that the maintenance of six months exclusive breastfeeding is also challenging for this group of mothers who were socially advantaged, well-educated and highly motivated to breastfeed their babies exclusively for six months.

  7. Costs of promoting exclusive breastfeeding at community level in three sites in South Africa.

    Directory of Open Access Journals (Sweden)

    Lungiswa Leonora Nkonki

    Full Text Available Community-based peer support has been shown to be effective in improving exclusive breastfeeding rates in a variety of settings.We conducted a cost analysis of a community cluster randomised-controlled trial (Promise-EBF, aimed at promoting exclusive infant feeding in three sites in South Africa. The costs were considered from the perspective of health service providers. Peer supporters in this trial visited women to support exclusive infant feeding, once antenatally and four times postpartum.The total economic cost of the Promise-EBF intervention was US$393 656, with average costs per woman and per visit of US$228 and US$52, respectively. The average costs per woman and visit in an operational 'non research' scenario were US$137 and US$32 per woman and visit, respectively. Investing in the promotion of exclusive infant feeding requires substantial financial commitment from policy makers. Extending the tasks of multi-skilled community health workers (CHWs to include promoting exclusive infant feeding is a potential option for reducing these costs. In order to avoid efficiency losses, we recommend that the time requirements for delivering the promotion of exclusive infant feeding are considered when integrating it within the existing activities of CHWs.This paper focuses on interventions for exclusive infant feeding, but its findings more generally illustrate the importance of documenting and quantifying factors that affect the feasibility and sustainability of community-based interventions, which are receiving increased focus in low income settings.

    - In verifying compliance with the Comprehensive Nuclear-Test-Ban Treaty (CTBT), there is a motivation to be effective, efficient and economical and to prevent abuse of the right to conduct an On-site Inspection (OSI) in the territory of a challenged State Party. In particular, it is in the interest of a State Party to avoid irrelevant search in specific areas. In this study we propose several techniques to determine `exclusion zones', which are defined as areas where an event could not have possibly occurred. All techniques are based on simple ideas of arrival time differences between seismic stations and thus are less prone to modeling errors compared to standard event location methods. The techniques proposed are: angular sector exclusion based on a tripartite micro array, half-space exclusion based on a station pair, and closed area exclusion based on circumferential networks.

  17. Model of reversible vesicular transport with exclusion

    International Nuclear Information System (INIS)

    Bressloff, Paul C; Karamched, Bhargav R

    2016-01-01

    A major question in neurobiology concerns the mechanics behind the motor-driven transport and delivery of vesicles to synaptic targets along the axon of a neuron. Experimental evidence suggests that the distribution of vesicles along the axon is relatively uniform and that vesicular delivery to synapses is reversible. A recent modeling study has made explicit the crucial role that reversibility in vesicular delivery to synapses plays in achieving uniformity in vesicle distribution, so called synaptic democracy (Bressloff et al 2015 Phys. Rev. Lett. 114 168101). In this paper we generalize the previous model by accounting for exclusion effects (hard-core repulsion) that may occur between molecular motor-cargo complexes (particles) moving along the same microtubule track. The resulting model takes the form of an exclusion process with four internal states, which distinguish between motile and stationary particles, and whether or not a particle is carrying vesicles. By applying a mean field approximation and an adiabatic approximation we reduce the system of ODEs describing the evolution of occupation numbers of the sites on a 1D lattice to a system of hydrodynamic equations in the continuum limit. We find that reversibility in vesicular delivery allows for synaptic democracy even in the presence of exclusion effects, although exclusion does exacerbate nonuniform distributions of vesicles in an axon when compared with a model without exclusion. We also uncover the relationship between our model and other models of exclusion processes with internal states. (paper)

    Full Text Available The aluminium (Al cation Al3+ is highly rhizotoxic and is a major stress factor to plants on acid soils, which cover large areas of tropical and boreal regions. Many woody plant species are native to acid soils and are well adapted to high Al3+ conditions. In tropical regions, both woody Al accumulator and non-Al accumulator plants occur, whereas in boreal regions woody plants are non-Al accumulators. The mechanisms of these adaptations can be divided into those that facilitate the exclusion of Al3+ from root cells (exclusion mechanisms and those that enable plants to tolerate Al3+ once it has entered the root and shoot symplast (internal tolerance mechanisms. The biochemical and molecular basis of these mechanisms have been intensively studied in several crop plants and the model plant Arabidopsis. In this review, we examine the current understanding of Al3+ exclusion and tolerance mechanisms from woody plants. In addition, we discuss the ecology of woody non-Al accumulator and Al accumulator plants, and present examples of Al3+ adaptations in woody plant populations. This paper complements previous reviews focusing on crop plants and provides insights into evolutionary processes operating in plant communities that are widespread on acid soils.

    The gambling industry has offered self-exclusion programs for quite a long time. Such measures are designed to limit access to gaming opportunities and provide problem gamblers with the help they need to cease or limit their gambling behaviour. However, few studies have empirically evaluated these programs. This study has three objectives: (1) to observe the participation in an improved self-exclusion program that includes an initial voluntary evaluation, phone support, and a mandatory meeting, (2) to evaluate satisfaction and usefulness of this service as perceived by self-excluders, (3) to measure the preliminary impact of this improved program. One hundred sixteen self-excluders completed a questionnaire about their satisfaction and their perception of the usefulness during the mandatory meeting. Among those participants, 39 attended an initial meeting. Comparisons between data collected at the initial meeting and data taken at the final meeting were made for those 39 participants. Data showed that gamblers chose the improved self-exclusion program 75% of the time; 25% preferred to sign a regular self-exclusion contract. Among those who chose the improved service, 40% wanted an initial voluntary evaluation and 37% of these individuals actually attended that meeting. Seventy percent of gamblers came to the mandatory meeting, which was a required condition to end their self-exclusion. The majority of participants were satisfied with the improved self-exclusion service and perceived it as useful. Major improvements were observed between the final and the initial evaluation on time and money spent, consequences of gambling, DSM-IV score, and psychological distress. The applicability of an improved self-exclusion program is discussed and, as shown in our study, the inclusion of a final mandatory meeting might not be so repulsive for self-excluders. Future research directives are also proposed.

    This paper explores the issue of inclusion in governance networks. It shows that mainstream understandings of inclusion in societal steering – perspectives on governance networks, neocorporatism and neopluralism – mainly focus on structural characteristics of potential members of governance...... networks and do not adequately explain who actually gets access to these networks. Instead I argue that we need to analyse actions taken consciously and deliberately to design inclusion – as well as exclusion – in governance networks, i.e. we need to bring agency into the analysis and analyse...

  6. “Not Designed for Us”: How Science Museums and Science Centers Socially Exclude Low-Income, Minority Ethnic Groups

    2014-01-01

    This paper explores how people from low-income, minority ethnic groups perceive and experience exclusion from informal science education (ISE) institutions, such as museums and science centers. Drawing on qualitative data from four focus groups, 32 interviews, four accompanied visits to ISE institutions, and field notes, this paper presents an analysis of exclusion from science learning opportunities during visits alongside participants’ attitudes, expectations, and conclusions about participation in ISE. Participants came from four community groups in central London: a Sierra Leonean group (n = 21), a Latin American group (n = 18), a Somali group (n = 6), and an Asian group (n = 13). Using a theoretical framework based on the work of Bourdieu, the analysis suggests ISE practices were grounded in expectations about visitors’ scientific knowledge, language skills, and finances in ways that were problematic for participants and excluded them from science learning opportunities. It is argued that ISE practices reinforced participants preexisting sense that museums and science centers were “not for us.” The paper concludes with a discussion of the findings in relation to previous research on participation in ISE and the potential for developing more inclusive informal science learning opportunities.

  7. ''Follow that quark!'' (and other exclusive stories)

    International Nuclear Information System (INIS)

    Carroll, A.S.

    1987-01-01

    Quarks are considered to be the basic constituents of matter. In a series of recent experiments, Carroll studied exclusive reactions as a means of determining the interactions between quarks. Quantum Chromo-dynamics (QCD) is the modern theory of the interaction of quarks. This theory explains how quarks are held together via the strong interaction in particles known as hadrons. Hadrons consisting of three quarks are called baryons. Hadrons made up of a quark and an antiquark are called mesons. In his lecture, Carroll describes what happens when two hadrons collide and scatter to large angles. The violence of the collision causes the gluons that bind the quarks in a particular hadron to temporarily lose their grip on particular quarks. Quarks scramble toward renewed unity with other quarks, and they undergo rearrangement, which generally results in additional new particles. A two-body exclusive reaction has occurred when the same number of particles exist before and after the collisions. At large angles these exclusive reactions are very rare. The labels on the quarks known as flavor enable the experimenter to follow the history of individual quarks in detail during these exclusive reactions. Carroll describes the equipment used in the experiment to measure short distance, hard collisions at large angles. The collisions he discusses occur when a known beam of mesons or protons collide with a stationary proton target. Finally, Carroll summarizes what the experiments have shown from the study of exclusive reactions and what light some of their results shed on the theory of QCD

    Much research has been devoted recently to developing technologies for renewable energy and improving the efficiency of the processes and devices used in industry and everyday life. Efficient solutions have been found using novel materials such as platinum and palladium-based catalysts for car exhaust systems, samarium-cobalt and neodymium-iron-boron permanent magnets for electrical motors, and so on. However, their realization has resulted in an increasing demand for rare elements and in their deficit, the development of new materials based on more abundant elements and new functionalities of traditional materials. Moreover, increasing environmental and health concerns demand substitution of toxic or hazardous substances with nature-friendly alternatives. In this context, this focus issue on advanced ceramics aims to review current trends in ceramics science and technology. It is related to the International Conference on Science and Technology of Advanced Ceramics (STAC) held annually to discuss the emerging issues in the field of ceramics. An important direction of ceramic science is the collaboration between experimental and theoretical sciences. Recent developments in density functional theory and computer technology have enabled the prediction of physical and chemical properties of ceramics, thereby assisting the design of new materials. Therefore, this focus issue includes articles devoted to theory and advanced characterization techniques. As mentioned above, the potential shortage of rare elements is becoming critical to the industry and has resulted in a Japanese government initiative called the 'Ubiquitous Element Strategy'. This focus issue also includes articles related to this strategy and to the associated topics of energy conversion, such as phosphors for high-efficiency lighting and photocatalysts for solar-energy harvesting. We hope that this focus issue will provide a timely overview of current trends and problems in ceramics science and

    One of the fundamental rules of nature and a pillar in the foundation of quantum theory and thus of modern physics is represented by the Pauli Exclusion Principle. We know that this principle is extremely well fulfilled due to many observations. Numerous experiments were performed to search for tiny violation of this rule in various systems. The experiment VIP at the Gran Sasso underground laboratory is searching for possible small violations of the Pauli Exclusion Principle for electrons leading to forbidden X-ray transitions in copper atoms. VIP is aiming at a test of the Pauli Exclusion Principle for electrons with high accuracy, down to the level of 10 −29 – 10 −30 , thus improving the previous limit by 3–4 orders of magnitude. The experimental method, results obtained so far and new developments within VIP2 (follow-up experiment at Gran Sasso, in preparation) to further increase the precision by 2 orders of magnitude will be presented

    The integration and adoption of digital technologies have enabled improvements in the quality of and inclusion in higher education. However, a significant proportion of the population has either remained or become digitally excluded. This systematic literature review elucidates the factors...... underlying the concepts of “digital exclusion” and the “digital divide” in higher education. The identified factors are grouped into three categories: social exclusion (i.e., low income, ICT-avoidance as the norm, lack of motivation and commitment, and physical or mental disability), digital exclusion (i.......e., lack of hardware devices and Internet services) and accessibility (which include the division between rural and urban areas, as well as disparities in ICT literacy and information literacy). These factors are multi-tiered and overlapping. Studies on the digital divide, digital exclusion, and barriers...

    The exclusive photoproduction of {Upsilon} has been studied with the ZEUS detector in ep collisions at HERA. The exponential slope, b, of the |t|-dependence of the cross section, where t is the squared four-momentum transfer at the proton vertex, has been measured. This constitutes the first measurement of the |t|-dependence of the {gamma}p{yields}{Upsilon}p cross section. The differential crosssections as a function of t at lower energies of {gamma}p centre-of-mass has been studied in exclusive diffractive photoproduction of J/{psi} mesons with the H1 detector. The exclusive electroproduction of two pions has been measured by the ZEUS experiment. The two-pion invariant-mass distribution is interpreted in terms of the pion electromagnetic form factor, assuming that the studied mass range includes the contributions of the {rho}, {rho} Prime and . {rho}'' vector-meson states.

    Full Text Available Abstract Background Breastfeeding is accepted as the natural form of infant feeding. For mothers to be able to breastfeed exclusively to the recommended six months, it is important to understand the factors that influence exclusive breastfeeding. The aim of the study was to identify factors associated with exclusive breastfeeding in Peninsular Malaysia. Methods This was a cross-sectional study involving 682 mother-infant pairs with infants up to six months attending maternal and child health section of the government health clinics in Klang, Malaysia. Data were collected by face-to-face interviews using a pre-tested structured questionnaire over 4 months in 2006. Data on breastfeeding were based on practice in the previous one month period. Logistic regression was used to assess the independent association between the independent variables and exclusive breastfeeding adjusting for infant age. Results The prevalence of exclusive breastfeeding among mothers with infants aged between one and six months was 43.1% (95% CI: 39.4, 46.8. In the multivariate model exclusive breastfeeding was positively associated with rural residence, Malay mothers, non-working and non-smoking mothers, multiparous mothers, term infants, mothers with husbands who support breastfeeding and mothers who practice bed-sharing. Conclusions Interventions that seek to increase exclusive breastfeeding should focus on women who are at risk of early discontinuation of breastfeeding.

    Teenage pregnancy is an important health issue globally and in Thailand Younger age mothers decide on the breastfeeding practices ofthe first 6-month. To find the rates of 6-month exclusive breastfeeding practices of teenage mothers and compare them with the rates of 6-month exclusive breastfeeding practices in mothers who are 20 years of age or more. Three thousand five hundred sixty three normal, postpartum women, who delivered without complications at the HRH Princess Maha Chakri Sirindhorn Medical Center in the Nakhon Nayok Province between 2010 and2013 were included in this study. At the second daypostpartum, the data of latch scores and the data of the practice of exclusive breastfeeding were collected Telephone follow-ups on the seventh, fourteenth, and forty-fifth postpartum days and at the second, fourth, and sixth month postpartum month were collected and used for exclusive breastfeeding data following discharge. Demographic data included the maternal age, parity, gestational age, marital status, occupation, religion, route ofdelivery, estimated blood loss, body mass index, nipple length, and the childs birth weight. The collected data was analyzed by the t-test, Chi-square, and odds ratio with 95% confidence interval. The percentage of teenage pregnancies was at 14.8% (527 cases). On postpartum day 2, the percentage of latch scores of 8 or less was 66.4%. At the seventh, fourteenth, and forty-fifth day and at the second, fourth, and sixth months postpartum, the exclusive breastfeeding rates were 88.5, 78.5, 57.6, 43.1, 32.9, and27.0%, respectively. Comparison of the 6-month exclusive breastfeeding rates between teenage mothers and mothers 20 years ofage or older were not statistically significant (pteenage mothers was at 27.0% and had no significant differences from the rates of mothers 20 years of age or more.

    Full Text Available Background: Breastfeeding is the unique source of nutrition and it plays an important role in the growth, development and survival of the infants. The initiation of breastfeeding within one hour and continuation of only breast milk up to six months ensure maximum benefits. The prevalence of exclusive breastfeeding in Bangladesh is 56% which is low. We designed this study to find out the factors influencing the duration of breastfeeding in Bangladeshi population. Objective: To study the factors influencing noncompliance to exclusive breastfeeding. Materials and Methods: This cross sectional study was conducted in Dhaka Shishu Hospital during the period January to June 2011. It includes 125 infant (1–12 months-mother pairs randomly selected from the inpatient and outpatient departments of Dhaka Shishu Hospital. Mother-infant pairs were divided into two groups based on continuation of only breastfeeding up to six months. Outcomes were compared between two groups. Results: In this study exclusive breastfeeding was found in 27.2% and nonexclusive breastfeeding was in 72.8% cases. It was found that in most cases (40% termination of breastfeeding was at 3--4 months. The study revealed that insufficient milk production due to poor position and attachment, social factors such as influence of husband and other family members, joining to service etc act as barrier to exclusive breastfeeding. Mass media and advice from health professionals had a higher influence on lower rate of exclusive breastfeeding. Women who were multiparous, housewives were more likely to maintain optimal breastfeeding. Conclusion: The present study reveals some important factors contributing to low rate of exclusive breastfeeding in Bangladesh.

    Hadronic and nuclear processes are covered, in which all final particles are measured at large invariant masses compared with each other, i.e., large momentum transfer exclusive reactions. Hadronic wave functions in QCD and QCD sum rule constraints on hadron wave functions are discussed. The question of the range of applicability of the factorization formula and perturbation theory for exclusive processes is considered. Some consequences of quark and gluon degrees of freedom in nuclei are discussed which are outside the usual domain of traditional nuclear physics. 44 refs., 7 figs

    We propose a new method for investigating the exclusion statistics of quasiparticles in conformal field theory (CFT) spectra. The method leads to one-particle distribution functions, which generalize the Fermi-Dirac distribution. For the simplest SU(n) invariant CFTs we find a generalization of Gentile parafermions, and we obtain new distributions for the simplest Z N -invariant CFTs. In special examples, our approach reproduces distributions based on 'fractional exclusion statistics' in the sense of Haldane. We comment on applications to fractional quantum Hall effect edge theories. copyright 1997 The American Physical Society

    Full Text Available Organic materials are usually thought of as electrical insulators. Progress in chemical synthesis, however, has brought us a rich variety of conducting organic materials, which can be classified into conducting polymers and molecular crystals. Researchers can realize highly conducting molecular crystals in charge-transfer complexes, where suitable combinations of organic electron donor or acceptor molecules with counter ions or other organic molecules provide charge carriers. By means of a kind of chemical doping, the charge-transfer complexes exhibit high electrical conductivity and, thanks to their highly crystalline nature, even superconductivity has been observed. This focus issue of Science and Technology of Advanced Materials is devoted to the research into such 'organic conductors'The first organic metal was (TTF(TCNQ, which was found in 1973 to have high conductivity at room temperature and a metal–insulator transition at low temperatures. The first organic superconductor was (TMTSF2PF6, whose superconductivity under high pressures was reported by J´erome in 1980. After these findings, the research on organic conductors exploded. Hundreds of organic conductors have been reported, among which more than one hundred exhibit superconductivity. Recently, a single-component organic conductor has been found with metallic conductivity down to low temperatures.In these organic conductors, in spite of their simple electronic structures, much new physics has arisen from the low dimensionality. Examples are charge and spin density waves, characteristic metal–insulator transitions, charge order, unconventional superconductivity, superconductor–insulator transitions, and zero-gap conductors with Dirac cones. The discovery of this new physics is undoubtedly derived from the development of many intriguing novel organic conductors. High quality single crystals are indispensable to the precise measurement of electronic states.This focus issue

    Hesselink, Wim H.; IJbema, Mark

    The standard implementation of mutual exclusion by means of a semaphore allows starvation of processes. Between 1979 and 1986, three algorithms were proposed that preclude starvation. These algorithms use a special kind of semaphore. We model this so-called buffered semaphore rigorously and provide

    2005-01-01

    This paper aims to show that a counterfactual approach to causation is not sufficient to provide a solution to the causal exclusion problem in the form of systematic overdetermination. Taking into account the truthmakers of causal counterfactuals provides a strong argument in favour of the identity of causes in situations of translevel, causation.

    2016-03-09

    Despite the importance of multiple psychosocial factors on nutrition-related behavior, very few studies have explored beyond the role of mothers' knowledge and perception of child-focused outcomes on the duration of exclusive breastfeeding in Africa. Our objective was to determine the relationships among mothers' knowledge, outcome expectancies, normative beliefs, and cessation of exclusive breastfeeding in rural Kenya. A cross-sectional survey was conducted among 400 mothers of children, 0-24 months old, in rural Kenya. Early child-feeding practices, knowledge of breastfeeding recommendations, beliefs associated with impact of exclusive breastfeeding on child- and mother-focused outcomes and perception of acceptability of exclusive breastfeeding by important others were examined. Cox regression analysis was used to assess the relationship between independent variables of interest and cessation of exclusive breastfeeding. Being knowledgeable of breastfeeding-related recommendations, positive beliefs on the impact of exclusive breastfeeding on child- focused outcomes, having a more positive perception of the impact of exclusive breastfeeding on mother-focused outcomes and a more positive perception of acceptability of exclusive breastfeeding by important others were associated with significantly lower risks of premature cessation of exclusive breastfeeding. In addition to knowledge levels, mothers' beliefs play an important role in mothers' decisions to practice exclusive breastfeeding. Mother's beliefs on the impact of exclusive breastfeeding on the mother's health, physical appearance and ability to engage in other activities were shown to have the strongest relationship with premature cessation of exclusive breastfeeding. Addressing these beliefs has the potential to contribute to more effective exclusive breastfeeding promotion efforts in rural Kenya.

  3. The exclusion from welfare benefits: Resentment and survey attrition in a randomized controlled trial in Mexico.

    Stecklov, Guy; Weinreb, Alexander; Winters, Paul

    2016-11-01

    Public policy programs must often impose limits on who may be eligible for benefits. Despite research on the impact of exclusion in developed countries, there is little evidence on how people react to being excluded from benefits in developing societies. Utilizing repeated waves of data from an experimental evaluation of Mexico's foundational PROGRESA antipoverty program, we examine the impact of exclusion and distinguish two separate forms. "Statistical exclusion" occurs where determination of benefits is based on randomized assignment to a treatment and control group. "Needs-based exclusion" occurs when benefits programs are designed to be selective rather than universal, basing eligibility on characteristics, like relative poverty, that are difficult to measure simply and accurately. Focusing on temporal variation in survey non-response as our behavioral outcome, we show that needs-based exclusion has much greater negative effects on continued participation than statistical exclusion. We also show that these effects are concentrated among the wealthy, that is, those furthest from the eligibility cut-off line. These findings reinforce general concerns about the validity of evaluation studies when incentives are at work. We discuss both the behavioral explanations that might underlie these findings as well as some potential approaches to reduce threats to evaluation validity. Copyright © 2016 Elsevier Inc.

    to examine postpartum maternal recall of their intentions to exclusively breast feed among breastfeeding women and identify its predictors. a cross-sectional descriptive study was conducted in a regional teaching hospital at Guangzhou, China between April 1 and July 14, 2014. 571 mothers who were within four days after delivery were recruited to the study. data were collected by four research assistants with maternal intention to breast feed data sheet, the Network Support for Breastfeeding Scale (NSBS), and a socio-demographic data sheet. greater than half of the mothers (69.5%) intended to exclusively breast feed. The logistic regression analysis revealed six variables which predicted postpartum maternal recall of their intentions to exclusively breast feed. They were support from husband, being breast-fed as an infant, previous breast feeding experience, attending antenatal breast feeding class, time of decision to breast feed, and the rating of the importance of my baby's health. health care professionals could develop strategies to enhance mothers' intention to exclusively breast feed, such as providing antenatal breast feeding class on internet, a strong focus on the benefits of exclusive breast feeding on the baby's health in the education programme, and more efforts directed toward educating school-aged children and adolescents to modify societal perceptions of what are considered normal infant feeding. Mothers' husband could be encouraged in supporting exclusive breast feeding. Copyright © 2017 Elsevier Ltd. All rights reserved.

Single-spin and double-spin asymmetries are measured, some of which are sensitive to the Generalised Parton Distributions E that are related to quark orbital angular momenta. The results, which are sensitive also to the pion-pole contribution to the production mechanism, are compared to the predictions of a phenomenological model.

    The exclusive two-body nonleptonic B→VV decays are investigated, within the factorization approximation, in the relativistic independent quark model based on a confining potential in the scalar-vector harmonic form. The branching ratios and the longitudinal polarization fraction (R L ) are calculated yielding the model predictions in agreement with experiment. Our predicted CP-odd fraction (R perpendicular ) for B→D*D (s) * decays are in general agreement with other model predictions and within the existing experimental limit.

  11. Immunoglobulin heavy chain exclusion in the shark.

    Directory of Open Access Journals (Sweden)

    Karolina Malecek

    2008-06-01

    Full Text Available The adaptive immune system depends on specific antigen receptors, immunoglobulins (Ig in B lymphocytes and T cell receptors (TCR in T lymphocytes. Adaptive responses to immune challenge are based on the expression of a single species of antigen receptor per cell; and in B cells, this is mediated in part by allelic exclusion at the Ig heavy (H chain locus. How allelic exclusion is regulated is unclear; we considered that sharks, the oldest vertebrates possessing the Ig/TCR-based immune system, would yield insights not previously approachable and reveal the primordial basis of the regulation of allelic exclusion. Sharks have an IgH locus organization consisting of 15-200 independently rearranging miniloci (VH-D1-D2-JH-Cmu, a gene organization that is considered ancestral to the tetrapod and bony fish IgH locus. We found that rearrangement takes place only within a minilocus, and the recombining gene segments are assembled simultaneously and randomly. Only one or few H chain genes were fully rearranged in each shark B cell, whereas the other loci retained their germline configuration. In contrast, most IgH were partially rearranged in every thymocyte (developing T cell examined, but no IgH transcripts were detected. The distinction between B and T cells in their IgH configurations and transcription reveals a heretofore unsuspected chromatin state permissive for rearrangement in precursor lymphocytes, and suggests that controlled limitation of B cell lineage-specific factors mediate regulated rearrangement and allelic exclusion. This regulation may be shared by higher vertebrates in which additional mechanistic and regulatory elements have evolved with their structurally complex IgH locus.

We argue that the BLM scale should be extracted from the squared amplitudes which are directly related to observables. (orig.)

    We consider the cross section limits for light dark matter cadnidates (m=0.4 to 10 GeV). We calculate the interaction of dark matter in the crust above underground dark matter detectors and find that in the intermediate cross section range, the energy loss of dark matter is sufficient to fall below the energy threshold of current underground experiments. This implies the existence of a window in the dark matter exclusion limits in the micro-barn range

  4. Robust Visual Tracking via Exclusive Context Modeling

    KAUST Repository

    Zhang, Tianzhu

    2015-02-09

    In this paper, we formulate particle filter-based object tracking as an exclusive sparse learning problem that exploits contextual information. To achieve this goal, we propose the context-aware exclusive sparse tracker (CEST) to model particle appearances as linear combinations of dictionary templates that are updated dynamically. Learning the representation of each particle is formulated as an exclusive sparse representation problem, where the overall dictionary is composed of multiple {group} dictionaries that can contain contextual information. With context, CEST is less prone to tracker drift. Interestingly, we show that the popular L₁ tracker [1] is a special case of our CEST formulation. The proposed learning problem is efficiently solved using an accelerated proximal gradient method that yields a sequence of closed form updates. To make the tracker much faster, we reduce the number of learning problems to be solved by using the dual problem to quickly and systematically rank and prune particles in each frame. We test our CEST tracker on challenging benchmark sequences that involve heavy occlusion, drastic illumination changes, and large pose variations. Experimental results show that CEST consistently outperforms state-of-the-art trackers.

    Exclusive vector meson photoproduction is studied in ultra-peripheral pPb collisions at $\\sqrt{s_{NN}} = 5.02$ TeV. The cross sections are measured as a function of the photon-proton centre-of-mass energy, extending the energy range explored by H1 and ZEUS Experiments at HERA. In addition, the differential cross sections ($d\\sigma/d\\left |t\\right|$), where $\\left |t\\right|\\approx p^{2}_{T}$ is the squared transverse momentum of produced vector mesons, are measured and the slope parameters are obtained. The results are compared to previous measurements and to theoretical predictions.

In this study, we look for any deviations that there might be from the Standard Model, and the results are used to set limits on the Anomalous Quartic Gauge Couplings. Finally, the latest p...

  6. Density profiles of the exclusive queuing process

    Science.gov (United States)

    Arita, Chikashi; Schadschneider, Andreas

    2012-12-01

    The exclusive queuing process (EQP) incorporates the exclusion principle into classic queuing models. It is characterized by, in addition to the entrance probability α and exit probability β, a third parameter: the hopping probability p. The EQP can be interpreted as an exclusion process of variable system length. Its phase diagram in the parameter space (α,β) is divided into a convergent phase and a divergent phase by a critical line which consists of a curved part and a straight part. Here we extend previous studies of this phase diagram. We identify subphases in the divergent phase, which can be distinguished by means of the shape of the density profile, and determine the velocity of the system length growth. This is done for EQPs with different update rules (parallel, backward sequential and continuous time). We also investigate the dynamics of the system length and the number of customers on the critical line. They are diffusive or subdiffusive with non-universal exponents that also depend on the update rules.

  7. Effect of Buffers on Aqueous Solute-Exclusion Zones around Ion-Exchange Resins

    Science.gov (United States)

    Zheng, Jian-ming; Wexler, Adam

    2009-01-01

    Interaction between charged surfaces in aqueous solution is a fundamental feature of colloid science. Theoretically, surface potential falls to half its value at a distance equal to a Debye length, which is typically on the order of tens to hundreds of nanometers. This potential prevents colloids from aggregating. On the other hand, long-range surface effects have been frequently reported. Here we report additional long-range effects. We find that charged latex particles in buffer solutions are uniformly excluded from several-hundred-micron-thick shells surrounding ion-exchange beads. Exclusion is observed whether the beads are charged similarly or oppositely to the particles. Hence, electrostatic interactions between bead and microsphere do not cause particle exclusion. Rather, exclusion may be the consequence of water molecules re-orienting to produce a more ordered structure, which then excludes the particles. PMID:19185312

    Jean-Marie Moutquin

    2009-04-01

    Full Text Available Background:This study examines the effect of exclusive versus non-exclusive breastfeeding on specific infant morbidities from birth to nine months, in Conakry (Guinea. Methods:A cross-sectional study was conducted on 1,167 mother-infant pairs who visited one of 20 immunization centres in Conakry for vaccination between the 45th and 270th days of the child’s life. Two data sources were used: the infant health book and an orally administered questionnaire completed with the mother. Data analyses included univariate cross-tabulations and multivariate logistic regression models to estimate the effect of breastfeeding on infant morbidity. Results:Exclusive breastfeeding decreased with the infant’s age. At six months of age, the proportion of infants who were exclusively breastfed was only 15.5%. After adjusting for the infant’s age, and the interaction between the type of breastfeeding and the infant’s age, exclusive breastfeeding significantly protected the infants against many of the studied morbidities (OR: 0.28, CI: 0.15-0.51 and specifically against diarrhoea (OR: 0.38; 95% CI: 0.17 – 0.86, respiratory infections (OR: 0.27; 95% CI: 0.14 – 0.50, and low growth rate (OR: 0.11; 95% CI: 0.02 – 0.46, but not for otitis, urinary infection, or meningitis. Conclusion:This investigation confirmed the protective effects of exclusive breastfeeding on some specific infant’s morbidities during the first nine months of life. The results of this study are of great importance for the development of an information program designed to encourage the exclusive breastfeeding among the mothers of Conakry, Guinea.

The latter, face unusual challenges as a result of being undocumented, forcing them to pursue mobility within a formal system that blocks their way. I review these tendencies through a "positive" lens, focusing mainly on Latino youth who are using different strategies to fight social exclusion. I aim to raise the paradoxical temporality , which indicates that as we learn and analyze more, we tend to move further away from the possibility of transforming pressing problems in society. I raise the question of how to intervene using more knowledge in the alarming situation of one of the most excluded social groups, Latino Youth and also of how to alert and visualize ways of integrating those youth who migrate and become undocumented.

  13. Transverse Imaging of the Proton in Exclusive Diffractive pp Scattering

    2006-01-01

    In a forthcoming paper we describe a new approach to rapidity gap survival (RGS) in the production of high-mass systems (H = dijet, Higgs, etc.) in exclusive double-gap diffractive pp scattering, pp -> p + H + p. It is based on the idea that hard and soft interactions are approximately independent (QCD factorization), and allows us to calculate the RGS probability in a model-independent way in terms of the gluon generalized parton distributions (GPDs) in the colliding protons and the pp elastic scattering amplitude. Here we focus on the transverse momentum dependence of the cross section. By measuring the ''diffraction pattern'', one can perform detailed tests of the interplay of hard and soft interactions, and even extract information about the gluon GPD in the proton from the data

    2010-01-01

    We discuss a method to construct observables protected against QCD uncertainties based on the angular distribution of the exclusive Bd -> K(*0}(-> Kpi) l+ l- decay. We focus on the identification and the interpretation of all the symmetries of the distribution. They constitute a key ingredient to construct a set of so-called transverse observables. We work in the framework of QCD factorization at NLO supplemented by an estimate of power-suppressed Lambda/mb corrections. A discussion of the new physics properties of two of the transverse asymmetries, AT^{(2)} and AT^{(5)}, is presented. A comparison between the transverse asymmetry AT^{(2)} and the forward-backward asymmetry shows that AT^{(2)} emerges as an improved version of it.

  16. Synthetic focusing in ultrasound modulated tomography

    KAUST Repository

    Kuchment, Peter; Kunyansky, Leonid

    2010-01-01

    Several hybrid tomographic methods utilizing ultrasound modulation have been introduced lately. Success of these methods hinges on the feasibility of focusing ultrasound waves at an arbitrary point of interest. Such focusing, however, is difficult to achieve in practice. We thus propose a way to avoid the use of focused waves through what we call synthetic focusing, i.e. by reconstructing the would-be response to the focused modulation from the measurements corresponding to realistic unfocused waves. Examples of reconstructions from simulated data are provided. This non-technical paper describes only the general concept, while technical details will appear elsewhere. © 2010 American Institute of Mathematical Sciences.

  18. Social Inclusion and Exclusion: A Review

    Directory of Open Access Journals (Sweden)

    Nabin Rawal

    2008-10-01

    Full Text Available The concept of social exclusion/inclusion figured prominently in the policy discourse in France in the mid 1970s. The concept was later adopted by the European Union in the late 1980s as a key concept in social policy and in many instances replaced the concept of poverty. This concept which had first appeared in Europe as a response to the crisis of the welfare State has now gained considerable currency over the last five years in both official and development discourses in Nepal. The issue gained considerable leverage when the Nepal Government recognized inclusion as a policy issue as one of the four pillars of 2003 Poverty Reduction Strategy Paper (PRSP, which is also Nepal's Tenth Plan. The debates surrounding inclusion/exclusion have ascended to conspicuous importance in the present political transition in Nepal with several groups such as Dalit, women, ethnic communities, donor communities, Madhesi communities and region voicing their demands for an inclusive state by virtue of which, the issue has now come to be a part of the popular public discourse. However, what has to be borne in mind is that the concept lacks universality in the way it has been defined and employed. While some claim that social exclusion is more illuminating and holds the promise of understanding disadvantaged groups better, others argue that this concept is so evocative, ambiguous, multidimensional and elastic that it can be defined in many different ways and owing to its ambiguity in definition it may mean all things to all people. Howsoever, the term has been used, defined, conceptualized, the article here makes an effort to review accessible literature on the topic.DOI = 10.3126/dsaj.v2i0.1362Dhaulagiri Journal of Sociology and Anthropology Vol.2 pp.161-180

  19. Exclusive ρ0 production at HERMES

    International Nuclear Information System (INIS)

    Rostomyan, Armine Armand

    2008-11-01

    In this thesis the exclusive electroproduction of ρ 0 mesons is analyzed using the data accumulated with the HERMES spectrometer in the years 2002-2005 by scattering the lepton beam of the HERA accelerator of the internal target of HERMES filled with transversely polarized hydrogen gas atoms. The ρ 0 production mechanism and, in a model-dependent way, the structure of the nucleon are studied by measuring the spin-density matrix elements (SDMEs), which parameterize the ρ 0 production and decay angular distribution. The decomposition of the angular distribution in terms of SDMEs was previously done for both polarized and unpolarized lepton beam and unpolarized target. Recently, the angular distribution was decomposed in terms of SDMEs also for a transversely polarized target. A first measurement of the 30 'transverse' SDMEs is reported in this thesis, yielding information on the degree of s-channel helicity conservation and natural-parity exchange in the case of a transversely polarized target. The measured SDMEs are implemented into the rhoMC Monte Carlo generator, which is currently the only one capable of fully simulating the exclusive ρ 0 production and decay for both unpolarized and polarized beam and target. The interest in SDMEs for a polarized target arose after it was shown that at leading twist the corresponding SDMEs can be related to the azimuthal transverse target-spin asymmetry in the cross section of exclusive ρ 0 production which is sensitive to the unknown nucleon helicity-ip GPDs. Since the GPD formalism is only valid for longitudinally polarized vector mesons produced by longitudinal photons, for the first time the transverse target-spin asymmetry of longitudinally polarized ρ 0 mesons is extracted and compared to the available theoretical predictions, specically considering possible problems with next-to-leading order corrections.

    The exclusive two-body nonleptonic B{yields}VV decays are investigated, within the factorization approximation, in the relativistic independent quark model based on a confining potential in the scalar-vector harmonic form. The branching ratios and the longitudinal polarization fraction (R{sub L}) are calculated yielding the model predictions in agreement with experiment. Our predicted CP-odd fraction (R{sub perpendicular}) for B{yields}D*D{sub (s)}* decays are in general agreement with other model predictions and within the existing experimental limit.

    We discuss which part of information about hadron structure encoded in the Generalized Parton Distributions (GPDs) [part of total GPD image] can be restored from the known amplitude of a hard exclusive process. The physics content of this partial image is analyzed. Among other things, we show that this partial image contains direct information about how the target hadron responses to the (string) quark-antiquark operator of arbitrary spin J. Explicit equations relating physics content of the partial image of GPDs directly to the data are derived. Also some new results concerning the dual parametrization of GPDs are presented

    2010-01-01

    The aim of this paper is to investigate the mathematical properties of a continuum model for diffusion of multiple species incorporating size exclusion effects. The system for two species leads to nonlinear cross-diffusion terms with double degeneracy, which creates significant novel challenges in the analysis of the system. We prove global existence of weak solutions and well-posedness of strong solutions close to equilibrium. We further study some asymptotics of the model, and in particular we characterize the large-time behavior of solutions. 2010 © Society for Industrial and Applied Mathematics.

  5. Power corrections to exclusive processes in QCD

    Energy Technology Data Exchange (ETDEWEB)

    Mankiewicz, Lech

    2002-02-01

    In practice applicability of twist expansion crucially depends on the magnitude to power corrections to the leading-twist amplitude. I illustrate this point by considering explicit examples of two hard exclusive processes in QCD. In the case of {gamma}{sup *}{gamma} {yields} {pi}{pi} amplitude power corrections are small enough such that it should be possible to describe current experimental data by the leading-twist QCD prediction. The photon helicity-flip amplitude in DVCS on a nucleon receives large kinematical power corrections which screen the leading-twist prediction up to large values of the hard photon virtuality.

  6. Death to perturbative QCD in exclusive processes?

    1994-04-01

    The authors discuss the question of whether perturbative QCD is applicable in calculations of exclusive processes at available momentum transfers. They show that the currently used method of determining hadronic quark distribution amplitudes from QCD sum rules yields wave functions which are completely undetermined because the polynomial expansion diverges. Because of the indeterminacy of the wave functions no statement can be made at present as to whether perturbative QCD is valid. The authors emphasize the necessity of a rigorous discussion of the subject and the importance of experimental data in the range of interest.

  13. Social inclusion/exclusion as matters of social (in)justice: a call for nursing action.

    Science.gov (United States)

    Yanicki, Sharon M; Kushner, Kaysi E; Reutter, Linda

    2015-06-01

    Social inclusion/exclusion involves just/unjust social relations and social structures enabling or constraining opportunities for participation and health. In this paper, social inclusion/exclusion is explored as a dialectic. Three discourses--discourses on recognition, capabilities, and equality and citizenship--are identified within Canadian literature. Each discourse highlights a different view of the injustices leading to social exclusion and the conditions supporting inclusion and social justice. An Integrated Framework for Social Justice that incorporates the three discourses is developed and used to critique the dominant focus on distributive justice within foundational Canadian nursing documents. We propose a broader conceptualization of social (in)justice that includes both relational and structural dimensions. Opportunities for multilevel interventions to promote social justice are identified. This framework is congruent with nursing's moral imperative to promote health equity and with the multiple roles played by nurses to promote social justice in everyday practice. © 2014 John Wiley & Sons Ltd.

  15. National simple: Constitutionality Analysis of Exclusions Sectorial

    Guilherme Adolfo dos Santos Mendes

    2016-06-01

    Full Text Available The Constitution defines the favored legal treatment for small businesses without making any explicit exception, including and especially for tax obligations. Nevertheless, all the laws, which have introduced tax benefits guided by this higher provision, have discriminated small companies due to the economic sector of activity. Known as “National Simple” and introduced by the Complementary Law No. 123/06, the current legislation did not extend its benefits to small production units of a number of industries, such as the automotive industry, the passenger transport industry, the energy industry and the industry of manufacture of weapons, beverages and tobacco products. By demonstrating the mistakes of the arguments in favor of such exclusions, the article holds up that none of these provisions meets constitutional standards. Furthermore, based on a critical analysis of the Positive Law, it is shown that the hidden desire behind the exclusions was to keep the economic sectors of high profitability under control of big corporations to the detriment of smaller initiatives.

    Full Text Available Intercellular communication was long thought to be regulated exclusively through direct contact between cells or via release of soluble molecules that transmit the signal by binding to a suitable receptor on the target cell, and/or via uptake into that cell. With the discovery of small secreted vesicular structures that contain complex cargo, both in their lumen and the lipid membrane that surrounds them, a new frontier of signal transduction was discovered. These “extracellular vesicles” (EV were initially thought to be garbage bags through which the cell ejected its waste. Whilst this is a major function of one type of EV, i.e., apoptotic bodies, many EVs have intricate functions in intercellular communication and compound exchange; although their physiological roles are still ill-defined. Additionally, it is now becoming increasingly clear that EVs mediate disease progression and therefore studying EVs has ignited significant interests among researchers from various fields of life sciences. Consequently, the research effort into the pathogenic roles of EVs is significantly higher even though their protective roles are not well established. The “Focus on extracellular vesicles” series of reviews highlights the current state of the art regarding various topics in EV research, whilst this review serves as an introductory overview of EVs, their biogenesis and molecular composition.

    2011-09-01

    Full Text Available The concept of social exclusion is context-specific and there is no uniform paradigm of exclusion across the world. This paper attempts to analyse exclusion of resource-poor groups in watershed development programmes in the Indian context. It aims to explore excluded community groups from the perspective of people’s equal opportunity and equal access to newly generated economic benefits in watershed development programmes. The paper also traces the determinant factors responsible for denial and exclusion of resource-poor groups and describes the detailed processes involved in their exclusion from institutional and livelihood opportunities in watershed programmes. At the same time, the paper also explores suggestions and views of resource-poor groups about their meaningful social inclusion in watershed programme. The Gadiwat Indo-German Watershed Development Project in Aurangabad district in the State of Maharashtra is studied in detail in terms of its social, economic and political realities through mix-method and multi-stakeholder approaches. The key findings of the paper are that landownership, caste, gender, membership in village institutions and/or watershed institutions or close relationship with members, as well as the limitations of the programme guidelines, are the major determinants of institutional inclusion and the extent of resulting economic benefits. The exclusion of resource-poor groups mainly takes the form of their exclusion from institutional representation. In order to promote meaningful social inclusion of resource-poor groups, there is need for a more livelihood-oriented focus and their equal representation and participation in watershed institutions.

    In American Samoa, initiation of breastfeeding is almost universal but exclusive breastfeeding, a promising target for obesity prevention, is short in duration. (1) To examine American Samoan mothers' feeding experiences and attitudes and beliefs about infant feeding and (2) to identify potential barriers to exclusive breastfeeding. Eighteen semi-structured interviews were conducted with American Samoan mothers at 16-32 days postpartum. Interviews focused on mother's knowledge and beliefs about infant feeding, how their infants were fed, why the mother had chosen this mode of infant feeding, and how decisions about feeding were made within her social surroundings. A thematic qualitative analysis was conducted to identify salient themes in the data. Intention to exclusively breastfeed did not predict practice; most women supplemented with formula despite intending to exclusively breastfeed. The benefits of breastfeeding were well-recognized, but the importance of exclusivity was missed. Formula-use was not preferred but considered an innocuous "back-up option" where breastfeeding was not possible or not sufficient for infant satiety. Identified barriers to exclusive breastfeeding included: the convenience of formula; perceptions among mothers that they were not producing enough breast milk; and pain while breastfeeding. The important support role of family for infant feeding could be utilized in intervention design. This study identified barriers to exclusive breastfeeding that can be immediately addressed by providers of breastfeeding support services. Further research is needed to address the common perception of insufficient milk in this setting. Copyright © 2015 Australian College of Midwives. Published by Elsevier Ltd. All rights reserved.

  1. Constraints to exclusive breastfeeding practice among breastfeeding mothers in Southwest Nigeria: implications for scaling up

    2012-04-01

    Full Text Available Abstract Background The practice of exclusive breastfeeding is still low despite the associated benefits. Improving the uptake and appropriating the benefits will require an understanding of breastfeeding as an embodied experience within a social context. This study investigates breastfeeding practices and experiences of nursing mothers and the roles of grandmothers, as well as the work-related constraints affecting nurses in providing quality support for breastfeeding mothers in Southwest Nigeria. Methods Using a concurrent mixed method approach, a structured questionnaire was administered to 200 breastfeeding mothers. In-depth interviews were also held with breastfeeding mothers (11, nurses (10 and a focus group discussion session with grandmothers. Results Breastfeeding was perceived as essential to baby's health. It strengthens the physical and spiritual bond between mothers and their children. Exclusive breastfeeding was considered essential but demanding. Only a small proportion (19% of the nursing mothers practiced exclusive breastfeeding. The survey showed the major constraints to exclusive breastfeeding to be: the perception that babies continued to be hungry after breastfeeding (29%; maternal health problems (26%; fear of babies becoming addicted to breast milk (26%; pressure from mother-in-law (25%; pains in the breast (25%; and the need to return to work (24%. In addition, the qualitative findings showed that significant others played dual roles with consequences on breastfeeding practices. The desire to practice exclusive breastfeeding was often compromised shortly after child delivery. Poor feeding, inadequate support from husband and conflicting positions from the significant others were dominant constraints. The nurses decried the effects of their workload on providing quality supports for nursing mothers. Conclusion Breastfeeding mothers are faced with multiple challenges as they strive to practice exclusive breastfeeding. Thus

  3. My Critique is Bigger than Yours: Constituting Exclusions in Critical Security Studies

    Directory of Open Access Journals (Sweden)

    David Roger Mutimer

    2009-10-01

    Full Text Available Critical Security Studies proceeds from the premise that words are world-making, that is that the ways we think about security are constitutive of the worlds of security we analyse. Turned to conventional security studies and the practices of global politics, this critical insight has revealed the ways in which the exclusions that are the focus of this conference have been produced. Perhaps most notable in this regard has been David Campbell's work, showing how the theory and practice of security are an identity discourse producing both insides and outsides, but the production of excluded others is a theme that runs through the critical scholarship on security in the past decade or more. This article turns the critical security studies gaze on itself, to explore the field's own complicity in the production of exclusions. The article reads three important instances of critical security studies for the inclusions and exclusions they produce: Ken Booth's Theory of World Securitv, the epilogue to David Campbell's Writing Security, and the CASE Collective Manifesto. The article concludes by asking about the nature of the inclusions and exclusions these divisions produce and the politics which those exclusions, in turn, (reproduce.

  6. Competitions between prosocial exclusions and punishments in finite populations

    2017-04-01

    Prosocial punishment has been proved to be a powerful mean to promote cooperation. Recent studies have found that social exclusion, which indeed can be regarded as a kind of punishment, can also support cooperation. However, if prosocial punishment and exclusion are both present, it is still unclear which strategy is more advantageous to curb free-riders. Here we first study the direct competition between different types of punishment and exclusion. We find that pool (peer) exclusion can always outperform pool (peer) punishment both in the optional and in the compulsory public goods game, no matter whether second-order sanctioning is considered or not. Furthermore, peer exclusion does better than pool exclusion both in the optional and in the compulsory game, but the situation is reversed in the presence of second-order exclusion. Finally, we extend the competition among all possible sanctioning strategies and find that peer exclusion can outperform all other strategies in the absence of second-order exclusion and punishment, while pool exclusion prevails when second-order sanctioning is possible. Our results demonstrate that exclusion is a more powerful strategy than punishment for the resolution of social dilemmas.

  8. Why every national deep-geological-isolation program needs a long-term science & technology component

    International Nuclear Information System (INIS)

    Budnitz, R J

    2006-01-01

    The objective of this paper is to set down the rationale for a separate Science & Technology (S&T) Program within every national deep-geological-isolation program. The fundamental rationale for such a Program is to provide a dedicated focus for longer-term science and technology activities that ultimately will benefit the whole repository mission. Such a Program, separately funded and with a dedicated staff (separate from the ''mainline'' activities to develop the repository, the surface facilities, and the transportation system), can devote itself exclusively to the development and management of a long-term science and technology program. Broad experience in governments worldwide has demonstrated that line offices are unlikely to be able to develop and sustain both the appropriate longer-term philosophy and the specialized skills associated with managing longer-term science and technology projects. Accomplishing both of these requires a separate dedicated program office with its own staff

    Full Text Available Abstract Background Exclusive breast feeding (EBF has important protective effects on the survival of infants and decreases risk for many early-life diseases. The purpose of this study was to assess the factors associated with EBF in Nigeria. Methods Data on 658 children less than 6 months of age were obtained from the Nigeria Demographic and Health Survey (NDHS 2003. The 2003 NDHS was a multi-stage cluster sample survey of 7864 households. EBF rates were examined against a set of individual, household and community level variables using a backward stepwise multilevel logistic regression method. Results The average EBF rate among infants younger than 6 months of age was 16.4% (95%CI: 12.6%-21.1% but was only 7.1% in infants in their fifth month of age. After adjusting for potential confounders, multivariate analyses revealed that the odds of EBF were higher in rich (Adjusted Odds Ratios (AOR = 1.15, CI = 0.28-6.69 and middle level (AOR = 2.45, CI = 1.06-5.68 households than poor households. Increasing infant age was associated with significantly less EBF (AOR = 0.65, 95%CI: 0.51-0.82. Mothers who had four or more antenatal visits were significantly more likely to engage in EBF (AOR = 2.70, 95%CI = 1.04-7.01. Female infants were more likely to be exclusively breastfed than male infants (AOR = 2.13, 95%CI = 1.03-4.39. Mothers who lived in the North Central geopolitical region were significantly more likely to exclusively breastfeed their babies than those mothers who lived in other geopolitical regions. Conclusions The EBF rate in Nigeria is low and falls well short of the expected levels needed to achieve a substantial reduction in child mortality. Antenatal care was strongly associated with an increased rate of EBF. Appropriate infant feeding practises are needed if Nigeria is to reach the child survival Millennium Development Goal of reducing infant mortality from about 100 deaths per 1000 live births to a target of 35 deaths per 1000 live

    1997-07-01

    The Waste Policy Institute, through a cooperative agreement with the U.S. Department of Energy's (DOE) Office of Science and Technology (OST), conducted two focus groups with people who live or work near DOE sites. The purpose of the focus groups was to gain a better understanding of the general community's information needs about the development of innovative technologies that are used in the cleanup of the sites. The authors wanted to better understand of what role these people want to play in the development of new technologies, how OST communication products can help facilitate that role, and the usefulness of current OST communication products. WPI held the focus groups in communities near the Idaho National Engineering and Environmental Laboratory (INEEL) and the Savannah River Site (SRS) because they are among the DOE sites that cannot be cleaned up before 2006. To include many facets of the communities, WPI randomly selected participants from membership lists of organized groups in each community including: elected officials, school boards, unions, chambers of commerce, economic development organizations, environmental organizations, health and human service organizations, and area clergy. While in the communities, WPI also interviewed stakeholders such as tribal representatives and a Citizens Advisory Board (CAB) member. Qualitative data gathered during the focus group sessions give some indication of general stakeholder opinions. However, the authors caution readers not to make broad assumptions about the general stakeholder audience based on the opinions of a limited number of general community stakeholders

  12. Commercialisation of science in Australia

    2003-01-01

    Major changes are occurring across the science and technology (S and T) landscape in this country. Messages from Federal and State Governments in recent times could not have been clearer - in return for 'taxpayer $ into ideas' (in other words, funding for front end basic research) there is an expectation that 'ideas will be translated into $' (in other words, commercialisation will be pursued aggressively). As we in Australian S and T are constantly reminded, with part justification only, Australian researchers (especially in the life sciences) are good at generating a wealth of ideas but not much wealth from ideas. It is claimed that despite scientific excellence, many in the sector are risk averse, immobile, prone to academic snobbery, better employees than employers, not entrepreneurial etc, etc. Regardless of the veracity of any of this, the 1990s has seen a change with many more scientists interested in pursuing the progression of ideas to research to invention to intellectual property to competitive advantage to commercialisation to wealth, jobs and social development to profits and tax dollars to increased support for innovation, R and D, basic research etc. In regard to biomedical research, it has been said that '... medical biotechnology was the first business with enough glamour to persuade eminent scientists that the entrepreneurial spirit and academic respectability are not mutually exclusive. Maybe it's OK to be a science-literate businessman and to make money from science. Successful biotech companies emerge when good science meets excellent management and that combination, in an enabling environment, attracts informed investors and partners. Biotech companies may focus on a single product, a portfolio, or a technology platform and the majority are destined not to become, and have no intention of becoming, an integrated biopharmaceutical or agrochemical company. Their capacity to raise funds is influenced by 'signals' that the technology, the people

    Full Text Available This study was designed to assess the frequency of exclusive breastfeeding in two health centers of Shahid Beheshti University of Medical sciences in Khak Sefid, Tehran, Iran. A total of 175 mothers, referred for the third dose of their infants' DPT vaccination program participated in the study by completing a questionnaire regarding characteristics of their pregnancy, delivery and exclusive breastfeeding within the first six months of birth. Two-variable analysis and logistic regression test were applied to evaluate factors influencing exclusive breastfeeding. Results indicated that the frequency of exclusive breastfeeding, i.e., breastfeeding within the first six months of birth without the use of any other food with or without vitamin supplementation, was 31.17% (95% CI=23.77%-38.57%, which means 48 infants of 154<179 days old Among 154 infants (<179 days old 48 did not have a history of being separated from their mothers. In logistic regression analysis, the variables which were directly associated with exclusive breastfeeding, with 0.05 significance level of alpha, included breastfeeding within the first hour of birth, eight times or more breastfeeding per day and receiving breastfeeding education during pregnancy. Variables with a negative association with breastfeeding included lack of breast milk, presence of a breast problem that could hinder breastfeeding, bottle feeding, physician or family's advice not to breastfeed and infant's refusal to breastfeed. Frequency of breastfeeding within the six months of birth is less than similar frequencies which are obtained by asking about breastfeeding on the day of the interview. It is recommended to apply real frequency for assessment, evaluation and programming of exclusive breastfeeding during the first six months of birth.

    The exclusive rare radiative B decays are studied in the relativistic independent quark model based on the confining potential in the scalar-vector harmonic form. The relevant form factors as well as the branching ratios for the processes B 0 →K *0 γ and B ± →K *± γ have been estimated in reasonable agreement with the available experimental data. The result compares well with several other model predictions. The calculation has been extended to the CKM-favored process B s →φγ and CKM-suppressed processes B u,d →ργ and B s →K * γ. copyright 1997 The American Physical Society

    2015-01-01

    The likelihood of resisting gender-stereotypic peer group norms, along with expectations about personal resistance, was investigated in 9- to 10-year-olds and 13- to 14-year-olds (N = 292). Participants were told about a stereotype conforming group (boys playing football; girls doing ballet) and a stereotype nonconforming group (boys doing ballet; girls playing football). Contrary to expectations from gender-stereotyping research, participants stated that they would personally resist gender-stereotypic norms, and more so than they would expect their peers to resist. However, expecting peers to resist declined with age. Participants expected that exclusion from the group was a consequence for challenging the peer group, and understood the asymmetrical status of gender stereotypes with an expectation that it would be more difficult for boys to challenge stereotypes than for girls. © 2014 The Authors.

    Full Text Available As the internet has become an integral part of everyday life, it is understood that patterns of racial stereotyping and discrimination found in the offline world are often reproduced online. In our paper, we examine two exclusionary practices in an online environment for adult toy collectors: First, the exclusion of non-white individuals who are expected to form immediate friendships with other non-white members; and second, the essentializing of racial issues when concerns over the lack of racial diversity in the toys are discussed. This dismissal is often directly connected to non-white members’ decisions to no longer participate, resulting in a new form of segregation within virtual space.

  17. Orthogonality catastrophe and fractional exclusion statistics

    We show that the N -particle Sutherland model with inverse-square and harmonic interactions exhibits orthogonality catastrophe. For a fixed value of the harmonic coupling, the overlap of the N -body ground state wave functions with two different values of the inverse-square interaction term goes to zero in the thermodynamic limit. When the two values of the inverse-square coupling differ by an infinitesimal amount, the wave function overlap shows an exponential suppression. This is qualitatively different from the usual power law suppression observed in the Anderson's orthogonality catastrophe. We also obtain an analytic expression for the wave function overlaps for an arbitrary set of couplings, whose properties are analyzed numerically. The quasiparticles constituting the ground state wave functions of the Sutherland model are known to obey fractional exclusion statistics. Our analysis indicates that the orthogonality catastrophe may be valid in systems with more general kinds of statistics than just the fermionic type.

    The concept of Generalized Parton Distributions (GPDs) combines the two-dimensional spatial information, given by form factors, with the longitudinal momentum information from the PDFs. Thus, GPDs provide a three-dimensional 'tomography' of the nucleon. Furthermore, according to Ji's sum rule, the GPDs H and E enable access to the total angular momenta of quarks, antiquarks and gluons. While H can be approached using electroproduction cross section, hard exclusive meson production off a transversely polarized target can help to constrain the GPD E. At the COMPASS experiment at CERN, two periods of data taking were performed in 2007 and 2010, using a longitudinally polarized 160 GeV/c muon beam and a transversely polarized NH{sub 3} target. This talk introduces the data analysis of the process μ + p → μ' + p' + V, and recent results are presented.

    We analyze completely exclusive 1 GeV/nucleon gold-emulsion reaction data with special emphasis on quantities which may help to settle the unsolved problem of which reaction mechanism produces the multifragmentation of heavy nuclei. We present results on correlations between target fragments and projectile fragments and among projectile fragments. In particular, we present for the first time the evolution of the mass yield distribution with the violence of the collisions which is characterized by the number of Z = 1 particles. We find that events producing Z = 2 particles have a different signature than those producing medium mass fragments. This shows that the agreement of the data with theories describing the inclusive mass yield by a single process: like a liquid gas phase transition: is accidental

  20. Exclusion from the Health Insurance Scheme

    2003-01-01

    A CERN pensioner, member of the Organization's Health Insurance Scheme (CHIS), recently provided fake documents in support of claims for medical expenses, in order to receive unjustified reimbursement from the CHIS. The Administrator of the CHIS, UNIQA, suspected a case of fraud: Accordingly, an investigation and interview of the person concerned was carried out and brought the Organization to the conclusion that fraud had actually taken place. Consequently and in accordance with Article VIII 3.12 of the CHIS Rules, it was decided to exclude this member permanently from the CHIS. The Organization takes the opportunity to remind Scheme members that any fraud or attempt to fraud established within the framework of the CHIS exposes them to: - disciplinary action, according to the Staff Rules and Regulations, for CERN members of the personnel; - definitive exclusion from the CHIS for members affiliated on a voluntary basis.

    Social inclusion and exclusion are concepts which have been widely associated with politics and policy in the first decade of the 2000s. People with mental health problems have become the focus of a range of social inclusion initiatives. A literature review was conducted to explore the peer-reviewed evidence relating social inclusion/exclusion and mental health. In total 36 papers were included in the review from the UK, Canada, Australia and Scandinavia. The papers had used a range of different approaches to research and evaluation. The included papers associated being socially included to: social roles and responsibilities such as employment, participation in social activities, environmental work and voting. Although some papers engaged in a critical discussion of the concept, many offered only simplistic accounts or definitions. Social inclusion is such a widely used term within political and policy discourses that it is surprising so little research is available within the mental health realm. There was a lack of clarity related to the concept of social exclusion and the qualitative studies focused entirely on the experiences of being excluded within an institutional or semi-institutional setting. The relationship between exclusion, inequality and injustice is identified and the relevance of the concept to current and future mental health policy is questioned. © 2012 Blackwell Publishing.

    Despite growing evidence that supports the importance of 6-month exclusive breastfeeding, few Canadian mothers adhere to this, and early weaning onto solids is a common practice. This study assessed infant feeding transitions during the first 6 months postpartum and factors that predicted exclusive breastfeeding to 3 and 6 months. This prospective cohort study was part of the Alberta Pregnancy Outcomes and Nutrition study (APrON). From an initial sample of 600 pregnant women recruited from Edmonton and Calgary, 402 mothers provided complete details at 3 months postpartum; 300 stayed on to provide information at 6 months postpartum. During pregnancy and at 3 and 6 months postpartum, data on maternal and infant socio-demographic, behavior, and feeding were collected. Even though there was a high rate of "ever having breastfed" (98.6%), exclusive breastfeeding rates for 3 and 6 months were 54.0% and 15.3%, respectively. After controlling for potential confounders, the study showed that mothers who held post-graduate university degrees were 3.76 times more likely to breastfeed exclusively for 6 months than those without a university degree (95% CI: 1.30-10.92; p = 0.015). In addition, mother of previous children were more likely to breastfeed exclusively for 6 months (OR: 2.21, 95% CI: 1.08-4.52; p = 0.031). Mothers who were in the highest quartile of the Iowa Infant Feeding Attitude Score were 4.29 and 5.40 times more likely to breastfeed exclusively for 3 months (95% CI: 1.31-14.08; p-trend < 0.001) and 6 months (95% CI: 2.75-10.60; P-trend < 0.001), respectively. The 6-month exclusive breastfeeding rate in Alberta is considerably below national and international breastfeeding recommendations. Professional advice that focuses on prenatal maternal knowledge, attitudes, and misperceptions may promote adherence to World Health Organization breastfeeding guidelines. Knowing that exclusive breastfeeding is less likely to take place among lower

    Full Text Available Ronald H Silverman1,2 1Department of Ophthalmology, Columbia University Medical Center, 2F.L. Lizzi Center for Biomedical Engineering, Riverside Research, New York, NY, USA Abstract: The use of focused ultrasound to obtain diagnostically significant information about the eye goes back to the 1950s. This review describes the historical and technological development of ophthalmic ultrasound and its clinical application and impact. Ultrasound, like light, can be focused, which is crucial for formation of high-resolution, diagnostically useful images. Focused, single-element, mechanically scanned transducers are most common in ophthalmology. Specially designed transducers have been used to generate focused, high-intensity ultrasound that through thermal effects has been used to treat glaucoma (via cilio-destruction, tumors, and other pathologies. Linear and annular transducer arrays offer synthetic focusing in which precise timing of the excitation of independently addressable array elements allows formation of a converging wavefront to create a focus at one or more programmable depths. Most recently, linear array-based plane-wave ultrasound, in which the array emits an unfocused wavefront and focusing is performed solely on received data, has been demonstrated for imaging ocular anatomy and blood flow. While the history of ophthalmic ultrasound extends back over half-a-century, new and powerful technologic advances continue to be made, offering the prospect of novel diagnostic capabilities.

    2018-01-23

    Previous rubber/virtual hand illusion studies have established important constraints for the illusion that an artificial effector becomes part of one's own body (perceived ownership), and that its actions are being caused by oneself (perceived agency). We can take these observed constraints to establish two of three Wegner's (Trends Cogn Sci 7:65-69; Wegner, Trends in Cognitive Sciences 7:65-69, 2003) criteria for the perception of personal agency: priority and consistency, but not Wegner's third criterion-exclusivity. In this study we tested with virtual hand illusion, whether exclusivity (participant is certain who was controlling the virtual effector) can also be established. We manipulated two factors: exclusivity and consistency. Our results show that on both ownership and agency judgments, consistency and exclusivity produced main effects, and the two effects interacted in an underadditive fashion. Taken together, these findings provide support for our suggestion to extend Wegner's agency theory to explain perceived body ownership, which in turn provides an integrative framework for interpreting constraints on ownership and agency illusions.

    Paris, O.; Fratzl, P.

    1999-01-01

    Small-angle scattering (SAS) of X-rays (SAXS) or neutrons (SANS) are a powerful tools to investigate inhomogeneities in the size range from ∼ 1 nm to ∼ 100 nm. Typical examples in materials science are pores, precipitates in metal alloys or nano-particles in composites. Frequently, these inhomogeneities are not spherical and their alignment is not random, quite in contrast to many other applications of SAS. This requires the use of pinhole geometry and area detectors for the experimental set-up. The present paper focuses on evaluation techniques of two-dimensional (2D) SAS-patterns from some materials investigated by the authors, i.e. metal alloys, carbon composites, wood and bone. Although the examples shown are derived exclusively from SAXS measurements, most of them could stem from SANS measurements as well. (author)

  11. Achieving conservation science that bridges the knowledge-action boundary.

    2013-08-01

    There are many barriers to using science to inform conservation policy and practice. Conservation scientists wishing to produce management-relevant science must balance this goal with the imperative of demonstrating novelty and rigor in their science. Decision makers seeking to make evidence-based decisions must balance a desire for knowledge with the need to act despite uncertainty. Generating science that will effectively inform management decisions requires that the production of information (the components of knowledge) be salient (relevant and timely), credible (authoritative, believable, and trusted), and legitimate (developed via a process that considers the values and perspectives of all relevant actors) in the eyes of both researchers and decision makers. We perceive 3 key challenges for those hoping to generate conservation science that achieves all 3 of these information characteristics. First, scientific and management audiences can have contrasting perceptions about the salience of research. Second, the pursuit of scientific credibility can come at the cost of salience and legitimacy in the eyes of decision makers, and, third, different actors can have conflicting views about what constitutes legitimate information. We highlight 4 institutional frameworks that can facilitate science that will inform management: boundary organizations (environmental organizations that span the boundary between science and management), research scientists embedded in resource management agencies, formal links between decision makers and scientists at research-focused institutions, and training programs for conservation professionals. Although these are not the only approaches to generating boundary-spanning science, nor are they mutually exclusive, they provide mechanisms for promoting communication, translation, and mediation across the knowledge-action boundary. We believe that despite the challenges, conservation science should strive to be a boundary science, which

The purpose was to understand what members of the interested and involved public want to know about technology development and ways to get that information to them. These data collection activities were used as a follow-up to two previously held focus groups with the general public near Idaho National Engineering and Environmental Laboratory (INEEL) and the Savannah River Site (SRS). Most participants from the first two focus groups said they did not have time and/or were not interested in participating in technology decision-making.

    Full Text Available We report the results on the search for exclusive production of W pairs in the LHC with data collected by the Compact Muon Solenoid detector in proton-proton collisions at √s = 7 TeV. The analysis comprises the two-photon production of a W pairs, pp → pW+ W− p → p νe± νµ∓ p. Two events are observed in data for pT(ℓ > 4 GeV, |η(ℓ| 20 GeV, in agreement with the standard model prediction of 2.2 ± 0.4 signal events with 0.84 ± 0.15 background events. Moreover, a study of the tail of the lepton pair transverse momentum distribution is performed to search for an evidence of anomalous quartic gauge couplings in the γγ → W+ W− vertex. As no events are observed in data, it results in a model-independent upper limits for the anomalous W quartic gauge couplings aW0,C/Λ2, which are of the order of 10−4.

    In the present work exclusive φ meson leptoproduction at HERMES experiment in DESY was studied using the data collected at HERA accelerator in the period from 1998 till 2000 and from 2006 till 2007 years. In the analysis unpolarized and longitudinally polarized hydrogen and deuteron targets were used, the beam consisted of longitudinally polarized leptons. Via measurement of the angular and momentum distribution of the φ meson decay products 23 spin density matrix elements (SDMEs) for the φ meson were obtained. The number of SDMEs was defined by the experiment conditions, e.g. by the beam and target polarization directions. For the mentioned time period φ meson SDMEs were defined at HERMES for the first time. The quantities U 1 , U 2 and U 3 which can be used to check presence of unnatural parity exchange (UPE) mechanism in phi meson production were calculated from SDMEs. All the results were obtained in 3 kinematic bins of Q 2 , 4 kinematic bins of t' and for the integrated kinematics. No statistically significant difference between the results for hydrogen and deuteron targets was observed. The UPE quantities were found to be zero within 2 σ for the integrated kinematics, indicating negligible contribution of UPE for the φ meson production which is in agreement with theory predictions. The test of s-channel helicity conservation hypothesis via comparison of corresponding SDME values showed helicity conservation for the φ meson production.

    The analysis of radiation danger of the Exclusion Zone objects was made. Here, the Zone is defined as the territory from which the population has been evacuated in 1986 owing to the Chernobyl accident and possible outflow of the contaminated substances out of the borders is potentially dangerous to the Ukraine. In the present work were analyzed such problems as sources of radiation danger in the Zone, ways of radionuclide migration out of the borders of the Zone in normal and emergency situations, the non-radiation (ecological) danger factors of the Zone objects, doses (individual and collective) from various sources and on separate ways of their formation, and the characteristics of radiation danger of the Zone objects. The conclusions are: (1) Radionuclide flows both from technologic and natural sources exceed those from Shelter objects, (2) Under emergency conditions, radionuclide flows and doze loading remain comparable with those from emergency sources, (3) To solve some management tasks in radiation situation, the basic works on the Shelter objects should be oriented to decrease probability of emergency occurrence and to reduce radiation influence (prevention wash-outs during high waters, fire-prevention measures in forests and strengthening of the control behind non-authorized use of objects in the Zone).

    The exclusive electroproduction of two pions in the mass range 0.4 < M{\\pi}{\\pi} < 2.5 GeV has been studied with the ZEUS detector at HERA using an integrated luminosity of 82 pb-1. The analysis was carried out in the kinematic range of 2 < Q2 < 80 GeV2, 32 < W < 180 GeV and |t| < 0.6 GeV2, where Q2 is the photon virtuality, W is the photon-proton centre-of-mass energy and t is the squared four-momentum transfer at the proton vertex. The two-pion invariant-mass distribution is interpreted in terms of the pion electromagnetic form factor, |F(M{\\pi}{\\pi})|, assuming that the studied mass range includes the contributions of the {\\rho}, {\\rho}' and {\\rho}" vector-meson states. The masses and widths of the resonances were obtained and the Q2 dependence of the cross-section ratios {\\sigma}({\\rho}' \\rightarrow {\\pi}{\\pi})/{\\sigma}({\\rho}) and {\\sigma}({\\rho}" \\rightarrow {\\pi}{\\pi})/{\\sigma}({\\rho}) was extracted.

    A comparison is made using size-exclusion chromatography (SEC) of synthetic polymers between fully porous particles (FPPs) and superficially porous particles (SPPs) with similar particle diameters, pore sizes and equal flow rates. Polystyrene molecular weight standards with a mobile phase of tetrahydrofuran are utilized for all measurements conducted with standard HPLC equipment. Although it is traditionally thought that larger pore volume is thermodynamically advantageous in SEC for better separations, SPPs have kinetic advantages and these will be shown to compensate for the loss in pore volume compared to FPPs. The comparison metrics include the elution range (smaller with SPPs), the plate count (larger for SPPs), the rate production of theoretical plates (larger for SPPs) and the specific resolution (larger with FPPs). Advantages to using SPPs for SEC are discussed such that similar separations can be conducted faster using SPPs. SEC using SPPs offers similar peak capacities to that using FPPs but with faster operation. This also suggests that SEC conducted in the second dimension of a two-dimensional liquid chromatograph may benefit with reduced run time and with equivalently reduced peak width making SPPs advantageous for sampling the first dimension by the second dimension separator. Additional advantages are discussed for biomolecules along with a discussion of optimization criteria for size-based separations. Copyright © 2016 Elsevier B.V. All rights reserved.

    2011-08-26

    A size-exclusion chromatography (SEC) method in N,N-dimethylformamide containing 0.1 M LiNO(3) is shown to be suitable for the determination of molar mass distributions of three classes of perfluorosulfonated ionomers, including Nafion(®). Autoclaving sample preparation is optimized to prepare molecular solutions free of aggregates, and a solvent exchange method concentrates the autoclaved samples to enable the use of molar-mass-sensitive detection. Calibration curves obtained from light scattering and viscometry detection suggest minor variation in the specific refractive index increment across the molecular size distributions, which introduces inaccuracies in the calculation of local absolute molar masses and intrinsic viscosities. Conformation plots that combine apparent molar masses from light scattering detection with apparent intrinsic viscosities from viscometry detection partially compensate for the variations in refractive index increment. The conformation plots are consistent with compact polymer conformations, and they provide Mark-Houwink-Sakurada constants that can be used to calculate molar mass distributions without molar-mass-sensitive detection. Unperturbed dimensions and characteristic ratios calculated from viscosity-molar mass relationships indicate unusually free rotation of the perfluoroalkane backbones and may suggest limitations to applying two-parameter excluded volume theories for these ionomers.

    Full Text Available The paper represents the first report of negative superposition in our country. Photo of randomly selected young, living woman was superimposed on the previously discovered female skull. Computer program Adobe Photoshop 7.0 was used in work. Digitilized photographs of the skull and face, after uploaded to computer, were superimposed on each other and displayed on the monitor in order to assess their possible similarities or differences. Special attention was payed to matching the same anthropometrical points of the skull and face, as well as following their contours. The process of fitting the skull and the photograph is usually started by setting eyes in correct position relative to the orbits. In this case, lower jaw gonions go beyond the face contour and gnathion is highly placed. By positioning the chin, mouth and nose their correct anatomical position cannot be achieved. All the difficulties associated with the superposition were recorded, with special emphasis on critical evaluation of work results in a negative superposition. Negative superposition has greater probative value (exclusion of identification than positive (possible identification. 100% negative superposition is easily achieved, but 100% positive - almost never. 'Each skull is unique and viewed from different perspectives is always a new challenge'. From this point of view, identification can be negative or of high probability.

    The type of gift bags given to new mothers at the time of discharge from the hospital can influence their confidence in breastfeeding. Most hospitals in the US continue to distribute commercial gift bags containing formula samples despite the reported negative influence of commercial bags on the duration of breastfeeding. This study compared breastfeeding outcomes in women receiving three different kinds of gift bags at discharge. A prospective intervention study was conducted during 2009-2010 in New Jersey. Three breastfeeding cohorts were recruited and assigned to three groups: COMMERCIAL received discharge bags containing formula samples, BF-INFO received breastfeeding information and supplies, and PUMP received breastfeeding information/supplies plus a manual breast pump. Follow-up contacts were at 2, 4, and 12 postpartum weeks to determine breastfeeding outcome. The mean durations of exclusive (EBF) and partial breastfeeding were compared between groups using ANOVA. A total of 386 participants completed the study. The mean EBF duration (weeks) in the PUMP (n = 138, 8.28 ± 4.86) and BF-INFO (n = 121, 7.87 ± 4.63) were significantly longer (P < 0.01) than COMMERCIAL (n = 127, 6.12 ± 4.49). The rate of EBF through 12 weeks in PUMP was most consistent. The mean duration of partial breastfeeding showed similar results: significantly longer in PUMP and BF-INFO than COMMERCIAL (P < 0.01).

    In the present work exclusive φ meson leptoproduction at HERMES experiment in DESY was studied using the data collected at HERA accelerator in the period from 1998 till 2000 and from 2006 till 2007 years. In the analysis unpolarized and longitudinally polarized hydrogen and deuteron targets were used, the beam consisted of longitudinally polarized leptons. Via measurement of the angular and momentum distribution of the φ meson decay products 23 spin density matrix elements (SDMEs) for the φ meson were obtained. The number of SDMEs was defined by the experiment conditions, e.g. by the beam and target polarization directions. For the mentioned time period φ meson SDMEs were defined at HERMES for the first time. The quantities U{sub 1}, U{sub 2} and U{sub 3} which can be used to check presence of unnatural parity exchange (UPE) mechanism in phi meson production were calculated from SDMEs. All the results were obtained in 3 kinematic bins of Q{sup 2}, 4 kinematic bins of t' and for the integrated kinematics. No statistically significant difference between the results for hydrogen and deuteron targets was observed. The UPE quantities were found to be zero within 2 σ for the integrated kinematics, indicating negligible contribution of UPE for the φ meson production which is in agreement with theory predictions. The test of s-channel helicity conservation hypothesis via comparison of corresponding SDME values showed helicity conservation for the φ meson production.

  7. Abnormal neural responses to social exclusion in schizophrenia.

    Directory of Open Access Journals (Sweden)

    Victoria B Gradin

    Full Text Available Social exclusion is an influential concept in politics, mental health and social psychology. Studies on healthy subjects have implicated the medial prefrontal cortex (mPFC, a region involved in emotional and social information processing, in neural responses to social exclusion. Impairments in social interactions are common in schizophrenia and are associated with reduced quality of life. Core symptoms such as delusions usually have a social content. However little is known about the neural underpinnings of social abnormalities. The aim of this study was to investigate the neural substrates of social exclusion in schizophrenia. Patients with schizophrenia and healthy controls underwent fMRI while participating in a popular social exclusion paradigm. This task involves passing a 'ball' between the participant and two cartoon representations of other subjects. The extent of social exclusion (ball not being passed to the participant was parametrically varied throughout the task. Replicating previous findings, increasing social exclusion activated the mPFC in controls. In contrast, patients with schizophrenia failed to modulate mPFC responses with increasing exclusion. Furthermore, the blunted response to exclusion correlated with increased severity of positive symptoms. These data support the hypothesis that the neural response to social exclusion differs in schizophrenia, highlighting the mPFC as a potential substrate of impaired social interactions.

    A snow-plough and slug models have been used to obtain the optimum matching conditions of the plasma in the focus. The dimensions of the plasma focus device are, inner electrode radius = 2 cm, outer electrode radius = 5.5 cm, and its length = 8 cm. It was found that the maximum magnetic energy of 12.26 kJ has to be delivered to plasma focus whose density is 10 19 /cm 3 at focusing time of 2.55 μs and with total external inductance of 24.2 n H. The same method is used to evaluate the optimum matching conditions for the previous coaxial discharge system which had inner electrode radius = 1.6 cm, outer electrode radius = 3.3 cm and its length = 31.5 cm. These conditions are charging voltage = 12 kV, capacity of the condenser bank = 430 μf, plasma focus density = 10 19 /cm 3 focusing time = 8 μs and total external inductance = 60.32 n H.3 fig., 2 tab

    Full Text Available Social exclusion is a wider concept than poverty and includes not only material conditions but also inability to participate in economic, social, political and cultural life. The essence of social exclusion is social relationships (more exactly breaking off relationships, which may mean not only pushing away some members of the society, but also breaking off relationships with the society from the side of a person himself/herself. The reasons of origin of social exclusion may be legal, political, economical, social and cultural. Nowadays social exclusion is predetermined by social-economic factors. According to Poviliūnas (2001, the problems of children’s social exclusion may be solved ensuring proper education, care of public health, safety and minimal life standard. Growing aggression and violence of schoolchildren and their social exclusion are nowadays an important issue of political debate and media reports. Often schoolchildren face the risk of social exclusion at school during the period of adolescence. The risk also depends on the social status of their family in the society and the relationship of the family members. The aim of the article is to identify characteristic features of schoolchildren at risk of social exclusion and analyze social support provided for them. A quantitative research was carried out to achieve the aim. The method of data collection is a questionnaire. 105 teachers working in 3 secondary schools in Lithuania participated in the research. The research results revealed that most often schoolchildren face the risk of social exclusion at school during adolescence period. They are characterized as incommunicative, unsociable, passive, and shy, do not trust others, are vulnerable, have learning problems and avoid collaborative activities. These schoolchildren usually come from families of social risk or single parent families. The support provided at school by teachers to schoolchildren at risk of social exclusion

    Full Text Available Interpersonal sensitivity, particularly threat of potential exclusion, is a critical condition in borderline personality disorder (BPD which impairs patients’ social adjustment. Current evidence-based treatments include group components, such as mentalization-based group therapy (MBT-G, in order to improve interpersonal functioning. These treatments additionally focus on the therapeutic alliance since it was discovered to be a robust predictor of treatment outcome. However, alliance is a multidimensional factor of group therapy, which includes the fellow patients, and may thus be negatively affected by the exclusion-proneness of BPD patients. The aim of this pilot study was to examine the predictive value of threat of social exclusion for the therapeutic alliance in MBT-G. In the first part of the study, social exclusion was experimentally induced in 23 BPD inpatients and 28 healthy subjects using the Cyberball paradigm, a virtual ball tossing game. The evoked level of threat was measured with the Need-Threat Scale (NTS which captures four dimensions of fundamental human needs, i.e., the need for belongingness, for self-esteem, for control, and for a meaningful existence. In the second part of the study, therapeutic alliance was measured on three dimensions, the therapists, the fellow patients and the group as a whole, using the Group-Questionnaire (GQ-D. BPD patients scored higher in their level of threat according to the NTS in both, the inclusion and the exclusion condition. The level of threat after exclusion predicted impairments of the therapeutic alliance in MBT-G. It was associated with more negative relationships, lower positive bonding and a lower positive working alliance with the fellow patients and lower positive bonding to the group as a whole whilst no negative prediction of the alliance to the therapists was found. Consequently, our translational study design has shown that Cyberball is an appropriate tool to use as an approach

  18. Predictors of exclusive breastfeeding: observations from the Alberta pregnancy outcomes and nutrition (APrON) study

    2013-01-01

    Background Despite growing evidence that supports the importance of 6-month exclusive breastfeeding, few Canadian mothers adhere to this, and early weaning onto solids is a common practice. This study assessed infant feeding transitions during the first 6 months postpartum and factors that predicted exclusive breastfeeding to 3 and 6 months. Methods This prospective cohort study was part of the Alberta Pregnancy Outcomes and Nutrition study (APrON). From an initial sample of 600 pregnant women recruited from Edmonton and Calgary, 402 mothers provided complete details at 3 months postpartum; 300 stayed on to provide information at 6 months postpartum. During pregnancy and at 3 and 6 months postpartum, data on maternal and infant socio-demographic, behavior, and feeding were collected. Results Even though there was a high rate of “ever having breastfed” (98.6%), exclusive breastfeeding rates for 3 and 6 months were 54.0% and 15.3%, respectively. After controlling for potential confounders, the study showed that mothers who held post-graduate university degrees were 3.76 times more likely to breastfeed exclusively for 6 months than those without a university degree (95% CI: 1.30-10.92; p = 0.015). In addition, mother of previous children were more likely to breastfeed exclusively for 6 months (OR: 2.21, 95% CI: 1.08-4.52; p = 0.031). Mothers who were in the highest quartile of the Iowa Infant Feeding Attitude Score were 4.29 and 5.40 times more likely to breastfeed exclusively for 3 months (95% CI: 1.31-14.08; p-trend breastfeeding rate in Alberta is considerably below national and international breastfeeding recommendations. Professional advice that focuses on prenatal maternal knowledge, attitudes, and misperceptions may promote adherence to World Health Organization breastfeeding guidelines. Knowing that exclusive breastfeeding is less likely to take place among lower-educated, primiparous women may help health practitioners focus their

    A key goal of research into quantum information processing is the development of technologies that are scaleable in complexity while allowing the mass manufacture of devices that promise transformative effects on information science. The demonstration that integrated photonics circuits could be made to perform operations that exploit the quantum nature of the photon has turned them into leading candidates for practical quantum information processing technologies. To fully achieve their promise, however, requires research from diverse fields. This focus issue provides a snapshot of some of the areas in which key advances have been made. We are grateful for the contributions from leading teams based around the globe and hope that the degree of progress being made in a challenging and exciting field is apparent from the papers published here.

  2. Exclusive Backward-Angle Omega Meson Electroproduction

    Energy Technology Data Exchange (ETDEWEB)

    Wenliang, Li [Univ. of Regina, Regina, SK (Canada)

    2017-10-01

    Exclusive meson electroproduction at different squared four-momenta of the exchanged virtual photon, Q2 , and at different four-momentum transfers, t and u, can be used to probe QCD's transition from hadronic degrees of freedom at the long distance scale to quark-gluon degrees of freedom at the short distance scale. Backward-angle meson electroproduction was previously ignored, but is anticipated to offer complimentary information to conventional forward-angle meson electroproduction studies on nucleon structure. This work is a pioneering study of backward-angle ω cross sections through the exclusive 1H(e, e'p)ω reaction using the missing mass reconstruction technique. The extracted cross sections are separated into the transverse (T), longitudinal (L), and LT, TT interference terms. The analyzed data were part of experiment E01-004 (Fπ-2), which used 2.6-5.2 GeV electron beams and HMS+SOS spectrometers in Jefferson Lab Hall C. The primary objective was to detect coincidence π in the forward-angle, where the backward-angle omega events were fortuitously detected. The experiment has central Q2 values of 1.60 and 2.45 GeV2 , at W = 2.21 GeV. There was significant coverage in phi and epsilon, which allowed separation of σT,L,LT,TT . The data set has a unique u coverage of -u ~ 0, which corresponds to -t > 4 GeV2 . The separated σT result suggest a flat ~ 1/Q1.33±1.21 dependence, whereas sigma_L seems to hold a stronger 1/Q9.43±6.28 dependence. The σL/σT ratio indicate σT dominance at Q2 = 2.45 GeV2 at the ~90% confidence level. After translating the results into the -t space of the published CLAS data, our data show evidence of a backward-angle omega electroproduction peak at both Q2 settings. Previously, this phenomenon showing both forward and backward-angle peaks was only observed in the meson

  3. Functional vision loss: a diagnosis of exclusion.

    Most cases of visual acuity or visual field loss can be attributed to ocular pathology or ocular manifestations of systemic pathology. They can also occasionally be attributed to nonpathologic processes or malingering. Functional vision loss is any decrease in vision the origin of which cannot be attributed to a pathologic or structural abnormality. Two cases of functional vision loss are described. In the first, a 58-year-old man presented for a baseline eye examination for enrollment in a vision rehabilitation program. He reported bilateral blindness since a motor vehicle accident with head trauma 4 years prior. Entering visual acuity was "no light perception" in each eye. Ocular health examination was normal and the patient made frequent eye contact with the examiners. He was referred for neuroimaging and electrophysiologic testing. The second case was a 49-year-old man who presented with a long history of intermittent monocular diplopia. His medical history was significant for psycho-medical evaluations and a diagnosis of factitious disorder. Entering uncorrected visual acuities were 20/20 in each eye, but visual field testing found constriction. No abnormalities were found that could account for the monocular diplopia or visual field deficit. A diagnosis of functional vision loss secondary to factitious disorder was made. Functional vision loss is a diagnosis of exclusion. In the event of reduced vision in the context of a normal ocular health examination, all other pathology must be ruled out before making the diagnosis of functional vision loss. Evaluation must include auxiliary ophthalmologic testing, neuroimaging of the visual pathway, review of the medical history and lifestyle, and psychiatric evaluation. Comanagement with a psychiatrist is essential for patients with functional vision loss.

    To describe the profile of women with children aged under 4 months living in the Brazilian state capitals and in the Federal District according to their working status and to analyze the influence of maternity leave on exclusive breastfeeding (EBF) among working women. This was a cross-sectional study with data extracted from the II National Maternal Breastfeeding Prevalence Survey carried out in 2008. Initially, a descriptive analysis of the profile of 12,794 women was performed, according to their working status and maternity leave and the frequency of maternity leave in the Brazilian regions and capitals. The study used a multiple model to identify the influence of maternity leave on EBF interruption, including 3766 women who declared they were working and were on maternity leave at the time of the interview. The outcome assessed in the study was the interruption of the EBF, classified by the WHO. Regarding the working status of the mothers, 63.4% did not work outside of their homes and among those who worked, 69.8% were on maternity leave. The largest prevalence among workers was of women older than 35 years of age, with more than 12 years of schooling, primiparous and from the Southeast and South regions. The lack of maternity leave increased by 23% the chance of EBF interruption. Maternity leave contributed to increase the prevalence of EBF in the Brazilian states capitals, supporting the importance of increasing the maternity leave period from four to six months.

    Comprehensive protein interaction maps can complement genetic and biochemical experiments and allow the formulation of new hypotheses to be tested in the system of interest. The computational analysis of the maps may help to focus on interesting cases and thereby to appropriately prioritize the validation experiments. We show here that, by automatically comparing and analyzing structurally similar regions of proteins of known structure interacting with a common partner, it is possible to identify mutually exclusive interactions present in the maps with a sensitivity of 70% and a specificity higher than 85% and that, in about three fourth of the correctly identified complexes, we also correctly recognize at least one residue (five on average) belonging to the interaction interface. Given the present and continuously increasing number of proteins of known structure, the requirement of the knowledge of the structure of the interacting proteins does not substantially impact on the coverage of our strategy that can be estimated to be around 25%. We also introduce here the Estrella server that embodies this strategy, is designed for users interested in validating specific hypotheses about the functional role of a protein-protein interaction and it also allows access to pre-computed data for seven organisms.

    Task conflicts among medical professions are essential problems to be solved in health care organizations. This study examined job conflicts between practical nurses (PNs) and registered nurses (RNs) in their duties and tasks with representative panelists from South Korea. This qualitative study used the Dacum Task Analysis process. Subject-matter experts in practical nursing were recruited utilizing stratified sampling: Ten experts developed job descriptions of PNs, and 20 validated the descriptions. The on-site tasks and duties of the PNs were measured by means of Dacum, and the results were reviewed by RNs using 3 focus-group interviews. The job description of PNs consisted of 10 duties and 117 tasks, overlapping with some tasks of RNs. Core tasks performed by PNs, such as invasive activities, led to task conflicts between the 2 groups, as these activities were regarded as the inherent duty of nursing professions. Thus, the RNs did not concede the expanded job scope of the PNs in terms of exclusive professionalism. To reduce task conflict, there is a need for the balanced development of nursing professionalism.

    Full Text Available Mexico's southern border is the entry point for different migratory flows, mainly from Central America, these flows have taken place under socioeconomic contexts and conditions which demand the constant livelihood strategies pursuit from people. This paper is focused on the agricultural laborers from Guatemalan origin, within coffee plantation farms at the Soconusco, Chiapas. The main objective is arguing how the lack of access -or restricted access- to education and the precarious inclusion to work and migration, have positioned youth population of migrant laborers, from Guatemalan origin, into social processes of social exclusion and vulnerability. It is concluded that conditions generated from these processes, preclude the generation of different work expectations, the access to a higher quality of life and the social mobility in a men and woman development crucial stage. The exposed information comes from quantitative and qualitative research methods. A nonrandom survey was applied to 129 families; 20 semi-structured interviews for children and adolescents within farms and 25 to actors involved in the recognition and performance of the human rights of migrant children in the southern Mexican border area.

    Full Text Available Social exclusion affects mental and physical health. The ability to regulate emotional responses to social exclusion is therefore essential for our well-being. As individual differences in detecting bodily signals (interoceptive sensitivity, IS have been associated with the ability of emotion regulation, we aimed at exploring whether IS fosters coping with social exclusion and flexibility in emotion regulation.The first study investigated subjective feelings and behavioral affiliation tendencies in response to ostracism using a cyberball paradigm. 69 participants were assessed who differed with respect to IS. The second study examined habitual emotion regulation processes focusing on suppression and reappraisal as well as IS in 116 participants. Main results were that the effect of ostracism on distress and behavioral affiliation tendencies were qualified by IS – being ostracized had less impact on participants with stronger IS. Furthermore, Study 2 revealed that IS was associated with habitually stronger emotion regulation strategies. We conclude that having access to bodily signals helps (IS reducing aversive states provoked by social exclusion, probably due to the fact that IS is associated with emotion regulation strategies..

  11. Is normal science good science?

    Directory of Open Access Journals (Sweden)

    Adrianna Kępińska

    2015-09-01

    Full Text Available “Normal science” is a concept introduced by Thomas Kuhn in The Structure of Scientific Revolutions (1962. In Kuhn’s view, normal science means “puzzle solving”, solving problems within the paradigm—framework most successful in solving current major scientific problems—rather than producing major novelties. This paper examines Kuhnian and Popperian accounts of normal science and their criticisms to assess if normal science is good. The advantage of normal science according to Kuhn was “psychological”: subjective satisfaction from successful “puzzle solving”. Popper argues for an “intellectual” science, one that consistently refutes conjectures (hypotheses and offers new ideas rather than focus on personal advantages. His account is criticized as too impersonal and idealistic. Feyerabend’s perspective seems more balanced; he argues for a community that would introduce new ideas, defend old ones, and enable scientists to develop in line with their subjective preferences. The paper concludes that normal science has no one clear-cut set of criteria encompassing its meaning and enabling clear assessment.

    Introduction. We present a new bibliometric indicator to measure journal specialisation over time, named the focus factor. This new indicator is based on bibliographic coupling and counts the percentage of re-citations given in subsequent years. Method. The applicability of the new indicator....... To validate re-citations as caused by specialisation, other possible causes were measured and correlated (obsolescence, journal self-citations and number of references). Results. The results indicate that the focus factor is capable of distinguishing between general and specialised journals and thus...... effectively measures the intended phenomenon (i.e., journal specialisation). Only weak correlations were found between journal re-citations and obsolescence, journal self-citations, and number of references. Conclusions. The focus factor successfully measures journal specialisation over time. Measures based...

    A search for exclusive or semi-exclusive photon pair production, pp to p(*) + photon pair + p(*) (where p(*) stands for a diffractively-dissociated proton), and the observation of exclusive and semi-exclusive electron pair production, pp to p(*) + ee + p(*), in proton-proton collisions at sqrt(s) = 7 TeV, are presented. The analysis is based on a data sample corresponding to an integrated luminosity of 36 inverse picobarns recorded by the CMS experiment at the LHC at low instantaneous luminosities. Candidate photon pair or electron pair events are selected by requiring the presence of two photons or a positron and an electron, each with transverse energy ET > 5.5 GeV and pseudorapidity abs(eta) < 2.5, and no other particles in the region abs(eta) < 5.2. No exclusive or semi-exclusive diphoton candidates are found in the data. An upper limit on the cross section for the reaction pp to p(*) + photon pair + p(*), within the above kinematic selections, is set at 1.18 pb at 95% confidence level. Seventeen exclusive or semi-exclusive dielectron candidates are observed, with an estimated background of 0.85 +/- 0.28 (stat.) events, in agreement with the QED-based prediction of 16.3 +/- 1.3 (syst.) events.

  4. Tanks Focus Area annual report FY2000

    2000-01-01

    The U.S. Department of Energy (DOE) continues to face a major radioactive waste tank remediation effort with tanks containing hazardous and radioactive waste resulting from the production of nuclear materials. With some 90 million gallons of waste in the form of solid, sludge, liquid, and gas stored in 287 tanks across the DOE complex, containing approximately 650 million curies, radioactive waste storage tank remediation is the nation's highest cleanup priority. Differing waste types and unique technical issues require specialized science and technology to achieve tank cleanup in an environmentally acceptable manner. Some of the waste has been stored for over 50 years in tanks that have exceeded their design lives. The challenge is to characterize and maintain these contents in a safe condition and continue to remediate and close each tank to minimize the risks of waste migration and exposure to workers, the public, and the environment. In 1994, the DOE's Office of Environmental Management (EM) created a group of integrated, multiorganizational teams focusing on specific areas of the EM cleanup mission. These teams have evolved into five focus areas managed within EM's Office of Science and Technology (OST): Tanks Focus Area (TFA); Deactivation and Decommissioning Focus Area; Nuclear Materials Focus Area; Subsurface Contaminants Focus Area; and Transuranic and Mixed Waste Focus Area

    No research, to date, has investigated the role of ethnic school composition (and intergroup contact) on European-American youth's use of stereotypes to explain interracial discomfort in the context of peer exclusion. In this study European-American 4 th , 7 th and 10 th grade students ( N = 414), attending low and high ethnically diverse public schools (with low and high self-reports of cross-race/ethnic friendships, respectively) evaluated three contexts of interracial exclusion (at lunch time, at a school dance, and at a sleepover). In addition to age and context effects, participants enrolled in high diversity schools were less likely to use stereotypes to explain racial discomfort, more likely to view racial exclusion as wrong, and more likely to estimate that racial exclusion occurs, than were participants enrolled in low diversity schools. These findings have implications for the role of social experience on racial attitudes and judgments about exclusion.

    The detection of four formaldehyde (H{sub 2}CO) maser regions toward young high-mass stellar objects in the last decade, in addition to the three previously known regions, calls for an investigation of whether H{sub 2}CO masers are an exclusive tracer of young high-mass stellar objects. We report the first survey specifically focused on the search for 6 cm H{sub 2}CO masers toward non high-mass star-forming regions (non HMSFRs). The observations were conducted with the 305 m Arecibo Telescope toward 25 low-mass star-forming regions, 15 planetary nebulae and post-AGB stars, and 31 late-type stars. We detected no H{sub 2}CO emission in our sample of non HMSFRs. To check for the association between high-mass star formation and H{sub 2}CO masers, we also conducted a survey toward 22 high-mass star-forming regions from a Hi-GAL (Herschel infrared Galactic Plane Survey) sample known to harbor 6.7 GHz CH{sub 3}OH masers. We detected a new 6 cm H{sub 2}CO emission line in G32.74−0.07. This work provides further evidence that supports an exclusive association between H{sub 2}CO masers and young regions of high-mass star formation. Furthermore, we detected H{sub 2}CO absorption toward all Hi-GAL sources, and toward 24 low-mass star-forming regions. We also conducted a simultaneous survey for OH (4660, 4750, 4765 MHz), H110α (4874 MHz), HCOOH (4916 MHz), CH{sub 3}OH (5005 MHz), and CH{sub 2}NH (5289 MHz) toward 68 of the sources in our sample of non HMSFRs. With the exception of the detection of a 4765 MHz OH line toward a pre-planetary nebula (IRAS 04395+3601), we detected no other spectral line to an upper limit of 15 mJy for most sources.

    Data science has attracted a lot of attention, promising to turn vast amounts of data into useful predictions and insights. In this article, we ask why scientists should care about data science. To answer, we discuss data science from three perspectives: statistical, computational, and human. Although each of the three is a critical component of data science, we argue that the effective combination of all three components is the essence of what data science is about.

  12. The lone gamer: Social exclusion predicts violent video game preferences and fuels aggressive inclinations in adolescent players.

    Gabbiadini, Alessandro; Riva, Paolo

    2018-03-01

    Violent video game playing has been linked to a wide range of negative outcomes, especially in adolescents. In the present research, we focused on a potential determinant of adolescents' willingness to play violent video games: social exclusion. We also tested whether exclusion can predict increased aggressiveness following violent video game playing. In two experiments, we predicted that exclusion could increase adolescents' preferences for violent video games and interact with violent game playing fostering adolescents' aggressive inclinations. In Study 1, 121 adolescents (aged 10-18 years) were randomly assigned to a manipulation of social exclusion. Then, they evaluated the violent content of nine different video games (violent, nonviolent, or prosocial) and reported their willingness to play each presented video game. The results showed that excluded participants expressed a greater willingness to play violent games than nonviolent or prosocial games. No such effect was found for included participants. In Study 2, both inclusionary status and video game contents were manipulated. After a manipulation of inclusionary status, 113 adolescents (aged 11-16 years) were randomly assigned to play either a violent or a nonviolent video game. Then, they were given an opportunity to express their aggressive inclinations toward the excluders. Results showed that excluded participants who played a violent game displayed the highest level of aggressive inclinations than participants who were assigned to the other experimental conditions. Overall, these findings suggest that exclusion increases preferences for violent games and that the combination of exclusion and violent game playing fuels aggressive inclinations. © 2017 Wiley Periodicals, Inc.

  13. Collective focusing ion accelerator

    International Nuclear Information System (INIS)

    Goldin, F.J.

    1986-01-01

    The principal subject of this dissertation is the trapping confinement of pure electron plasmas in bumpy toroidal magnetic fields, with particular attention given to the trapping procedure and the behavior of the plasma during the final equilibrium. The most important aspects of the equilibrium studied were the qualitative nature of the plasma configuration and motion and its density, distribution and stability. The motivation for this study was that an unneutralized cloud of electrons contained in a toroidal system, sufficiently dense and stable, may serve to electrostatically focus ions (against centrifugal and self space charge forces) in a cyclic ion accelerator. Such an accelerator, known as a Collective Focusing Ion Accelerator (CFIA) could be far smaller than conventional designs (which use external magnetic fields directly to focus the ions) due to the smaller gyro-radium of an electron in a magnetic field of given strength. The electron cloud generally drifted poloidally at a finite radius from the toroidal minor axis. As this would preclude focusing ions with such clouds, damping this motion was investigated. Finite resistance in the normally perfectly conductive vessel wall did this. In further preparation for a working CFIA, additional experiments studied the effect of ions on the stability of the electron cloud

    The primary objective of this project is to provide a relatively simple pulsed power source for high density pulsed fusion studies with a variety of DT and other fusion microexplosion targets. The plasma focus operated on DT at 1 MJ should produce greater than or equal to 10 15 DT neutrons per pulse corresponding to 2800 J of nuclear energy release and for low pressure operation and appropriately configured high Z anode center should yield an x-ray burst of about 1000 J with a substantial fraction of this x-ray energy concentrated in the 5-100 kV range. Because of its x-ray and neutron production potential, the operation of the focus as an x-ray source is also under study and an initial design study for a repetitively pulsed 1 MJ plasma focus as a pulsed neutron materials testing source has been completed. The plasma focus seems particularly appropriate for application as a materials testing source for pulsed fusion reactors, for example, based on laser driven fusion microexplosions. The construction status of the device is described

  19. Factors that influence women's dispositions toward science

    Atria, Catherine Graczyk

    Females have been underrepresented in the study of science and science careers for decades although advancements have been made in closing this gender gap, the gap persists particularly in the physical sciences. Variables which influence a woman's desire to pursue and maintain a science course of study and career must be discovered. The United States lags behind other industrialized countries in the fields of science, math, and engineering. Females comprise an estimated half of the population; their potential contributions cannot be ignored or overlooked. This retrospective research study explores the personal experiences of ten women enrolled in science majors, with science related career plans. The goal of this study is to describe the factors that influence the participants' interest in science. The findings, the effect of science coursework, science teachers' personality and manner, other influential educational personnel, role models and mentors, external influences exclusive of school, parental influence, locus of control and positive attitudes toward science confirm what other researchers have found.

    Recent reform efforts in science education focus on scientific literacy for all citizens. In order to be scientifically literate, an individual must have informed understandings of nature of science (NOS), scientific inquiry, and science content matter. This study specifically focused on Science Olympiad students' understanding of NOS as one piece of scientific literacy. Research consistently shows that science students do not have informed understandings of NOS (Abd-El-Khalick, 2002; Bell, Blair, Crawford, and Lederman, 2002; Kilcrease and Lucy, 2002; Schwartz, Lederman, and Thompson, 2001). However, McGhee-Brown, Martin, Monsaas and Stombler (2003) found that Science Olympiad students had in-depth understandings of science concepts, principles, processes, and techniques. Science Olympiad teams compete nationally and are found in rural, urban, and suburban schools. In an effort to learn from students who are generally considered high achieving students and who enjoy science, as opposed to the typical science student, the purpose of this study was to investigate Science Olympiad students' understandings of NOS and the experiences that formed their understandings. An interpretive, qualitative, case study method was used to address the research questions. The participants were purposefully and conveniently selected from the Science Olympiad team at a suburban high school. Data collection consisted of the Views of Nature of Science -- High School Questionnaire (VNOS-HS) (Schwartz, Lederman, & Thompson, 2001), semi-structured individual interviews, and a focus group. The main findings of this study were similar to much of the previous research in that the participants had informed understandings of the tentative nature of science and the role of inferences in science, but they did not have informed understandings of the role of human imagination and creativity, the empirical nature of science, or theories and laws.

    Full Text Available Objectives: To describe the profile of women with children aged under 4 months living in the Brazilian state capitals and in the Federal District according to their working status and to analyze the influence of maternity leave on exclusive breastfeeding (EBF among working women. Methods: This was a cross-sectional study with data extracted from the II National Maternal Breastfeeding Prevalence Survey carried out in 2008. Initially, a descriptive analysis of the profile of 12,794 women was performed, according to their working status and maternity leave and the frequency of maternity leave in the Brazilian regions and capitals. The study used a multiple model to identify the influence of maternity leave on EBF interruption, including 3766 women who declared they were working and were on maternity leave at the time of the interview. The outcome assessed in the study was the interruption of the EBF, classified by the WHO. Results: Regarding the working status of the mothers, 63.4% did not work outside of their homes and among those who worked, 69.8% were on maternity leave. The largest prevalence among workers was of women older than 35 years of age, with more than 12 years of schooling, primiparous and from the Southeast and South regions. The lack of maternity leave increased by 23% the chance of EBF interruption. Conclusion: Maternity leave contributed to increase the prevalence of EBF in the Brazilian states capitals, supporting the importance of increasing the maternity leave period from four to six months. Resumo: Objetivos: Descrever perfil das mulheres com filhos menores de 4 meses residentes nas capitais brasileiras e no Distrito Federal segundo situação de trabalho e analisar a influência da licença-maternidade sobre o aleitamento materno exclusivo entre as mulheres trabalhadoras. Métodos: Trata-se de um estudo transversal com dados extraídos da II Pesquisa Nacional de Prevalência do Aleitamento Materno realizada em 2008

    Full Text Available This paper reports on the findings obtained from a study conducted in 2009: “Exclusión educativa y abandono (deserción escolar en la enseñanza secundaria en Costa Rica” [Education Exclusion and Dropping out in Costa Rica], focused on the students from the 7th to the 11th grades of the General Basic Education. For this research, fieldwork was carried out in 22 institutions, in different educational regions of the country. Interviews were conducted with the school principals and counselors in each of the institutions visited. Focal groups were organized with students and parents in order to –as naturalism and qualitative focus suggest –understand the meaning of education exclusion and dropping out from the point of view of the different agents involved– principals, counselors, students, parents. A relevant conceptual aspect included in this study is the analysis of the problems related to dropping out and exclusion, generally, in a nonjudgmental way, to characterize this phenomenon.

    Understanding the role of different planetary surface formation processes within our Solar System is one of the fundamental goals of planetary science research. There has been a revolution in planetary surface observations over the last 8 years, especially in 3D imaging of surface shape (down to resolutions of 10cm) and subsequent terrain correction of imagery from orbiting spacecraft. This has led to the ability to be able to overlay different epochs back to the mid-1970s, examine time-varying changes (such as impact craters, RSLs, CO2 geysers, gullies, boulder movements and a host of ice-related phenomena). Consequently we are seeing a dramatic improvement in our understanding of surface formation processes. Since January 2004 the ESA Mars Express has been acquiring global data, especially HRSC stereo (12.5-25m nadir images) with 98% coverage with images ≤100m and more than 70% useful for stereo mapping (e.g. atmosphere sufficiently clear). It has been demonstrated [Gwinner et al., 2010] that HRSC has the highest possible planimetric accuracy of ≤25m and is well co-registered with MOLA, which represents the global 3D reference frame. HRSC 3D and terrain-corrected image products therefore represent the best available 3D reference data for Mars. Recently [Gwinner et al., 2015] have shown the ability to generate mosaiced DTM and BRDF-corrected surface reflectance maps. NASA began imaging the surface of Mars, initially from flybys in the 1960s with the first orbiter with images ≤100m in the late 1970s from Viking Orbiter. The most recent orbiter to begin imaging in November 2006 is the NASA MRO which has acquired surface imagery of around 1% of the Martian surface from HiRISE (at ≈25cm) and ≈5% from CTX (≈6m) in stereo. Unfortunately, for most of these NASA images, especially MGS, MO, VO and HiRISE their accuracy of georeferencing is often worse than the quality of Mars reference data from HRSC. This reduces their value for analysing changes in time

    1996-01-01

    The focusing of electromagnetic waves inside a slab has been examined together with two special cases in which the slab is reduced to a single interface or a single medium. To that end the exact solutions for the fields inside a layered medium have been used, given in terms of the outside current source in order to obtain the solutions for the focused electric field inside a slab. Both exact and asymptotic solutions of the problem have been considered, and the validity of the latter has been discussed. The author has developed a numerical algorithm for evaluation of the diffraction integral with special emphasis on reducing the computing time. The numerical techniques in the paper can be readily applied to evaluate similar diffraction integrals occurring e.g. in microstrip antennas. 46 refs

  5. Magnetic Focusing Horn

    1974-01-01

    This magnetic focusing horn was used for the AA (antiproton accumulator). Its development was an important step towards using CERN's Super Proton Synchrotron as a proton - antiproton collider. This eventually led to the discovery of the W and Z particles in 1983. Making an antiproton beam took a lot of time and effort. Firstly, protons were accelerated to an energy of 26 GeV in the PS and ejected onto a metal target. From the spray of emerging particles, a magnetic horn picked out 3.6 GeV antiprotons for injection into the AA through a wide-aperture focusing quadrupole magnet. For a million protons hitting the target, just one antiproton was captured, 'cooled' and accumulated. It took 3 days to make a beam of 3 x 10^11 -, three hundred thousand million - antiprotons.

    Theoretical analysis is made of an intense relativistic electron beam, such as would be available from a linear collider, moving through a plasma of increasing density, but density always less than that of the beam (underdense). In this situation, the plasma electrons are expelled from the beam channel and the electrons are subject to an ever-increasing focusing force provided by the channel ions. Analysis is made on the beam radiation energy loss in the classical, the transition, and the quantum regimes. It is shown that the focuser is insensitive to the beam energy spread behaviors in the nonclassical regimes, the radiation limit on lenses (the Oide limit) can be exceeded. The sensitivity of the system to the topic mismatch and the nonlinearity is also analyzed. Examples are given with SLC-type and TLC-type parameters. 9 refs., 1 tab

  7. Line broadening by focusing

    It is pointed out that the spectral width of a quasi-monochromatic light beam broadens when the beam is focused. A quantitative formula for this broadening is derived from classical wave theory. The effect is shown to explain some experiments on laser beams done by E. Panarella which that author has explained under the ad-hoc hypothesis that the frequency of the photons changes along with the intensity of the light beam. The line broadening by focusing might also contribute to gas ionization by incident light when the ionization potential is well above the mean photon energy. Some remarks are made on some direct applications of the Heisenberg relations in comparison with our treatment. (Author) [pt

    Full Text Available On the initial problem the gender gap in enrollment in engineering careers, this paper analyzes the link between masculinity attribution of science and technology, and the perception of symbolic violence in the everyday experience of women trying to study these careers. From testimonies and narrations, I explore the experiences of students to identify assumptions about how the subjects and formed in these areas and should be, as well as the possibilities, capabilities and limitations that are assigned to them, contributing from the empiria to a conceptualization of modes of exclusion and delegitimization that support the formation of a strongly masculinized scene.

    Objective Trauma-Focused Cognitive-Behavioral Therapy (TF-CBT) is a conjoint parent-child treatment developed by Cohen, Mannarino, and Deblinger that uses cognitive-behavioral principles and exposure techniques to prevent and treat posttraumatic stress, depression, and behavioral problems. This review defined TF-CBT, differentiated it from other models, and assessed the evidence base. Methods Authors reviewed meta-analyses, reviews, and individual studies (1995 to 2013). Databases surveyed were PubMed, PsycINFO, Applied Social Sciences Index and Abstracts, Sociological Abstracts, Social Services Abstracts, PILOTS, the ERIC, and the CINAHL. They chose from three levels of research evidence (high, moderate, and low) on the basis of benchmarks for number of studies and quality of their methodology. They also described the evidence of effectiveness. Results The level of evidence for TF-CBT was rated as high on the basis of ten RCTs, three of which were conducted independently (not by TF-CBT developers). TF-CBT has demonstrated positive outcomes in reducing symptoms of posttraumatic stress disorder, although it is less clear whether TF-CBT is effective in reducing behavior problems or symptoms of depression. Limitations of the studies include concerns about investigator bias and exclusion of vulnerable populations. Conclusions TF-CBT is a viable treatment for reducing trauma-related symptoms among some children who have experienced trauma and their nonoffending caregivers. Based on this evidence, TF-CBT should be available as a covered service in health plans. Ongoing research is needed to further identify best practices for TF-CBT in various settings and with individuals from various racial and ethnic backgrounds and with varied trauma histories, symptoms, and stages of intellectual, social, and emotional development.

    Happiness is increasingly named as a target of policy measures. Apart from the confusing fact that the attention-grabbing catchword ‘happiness’ refers to ‘life satisfaction’ in most cases, this approach appears preferable to alternatives as utility functions, magic polygons or to the opaque decisions of politicians. A life-satisfaction-oriented policy would prove welfare-improving, focusing on fair distribution of income and wealth, social goals and institutional goals such as health,...

    The US Department of Enregy (DOE) Subsurface Contaminants Focus Area is developing technologies to address environmental problems associated with hazardous and radioactive contaminants in soil and groundwater that exist throughout the DOE complex, including radionuclides, heavy metals; and dense non-aqueous phase liquids (DNAPLs). More than 5,700 known DOE groundwater plumes have contaminated over 600 billion gallons of water and 200 million cubic meters of soil. Migration of these plumes threatens local and regional water sources, and in some cases has already adversely impacted off-site rsources. In addition, the Subsurface Contaminants Focus Area is responsible for supplying technologies for the remediation of numerous landfills at DOE facilities. These landfills are estimated to contain over 3 million cubic meters of radioactive and hazardous buried Technology developed within this specialty area will provide efective methods to contain contaminant plumes and new or alternative technologies for development of in situ technologies to minimize waste disposal costs and potential worker exposure by treating plumes in place. While addressing contaminant plumes emanating from DOE landfills, the Subsurface Contaminants Focus Area is also working to develop new or alternative technologies for the in situ stabilization, and nonintrusive characterization of these disposal sites

    The Laboratório de Aceleradores e Tecnologias de Radiação (LATR) at the Campus Tecnológico e Nuclear, of Instituto Superior Técnico (IST) has a horizontal electrostatic particle accelerator based on the Van de Graaff machine which is used for research in the area of material characterization. This machine produces alfa (He+) and proton (H+) beams of some μA currents up to 2 MeV/q energies. Beam focusing is obtained using a cylindrical lens of the Einzel type, assembled near the high voltage terminal. This paper describes the developed system that automatically focuses the ion beam, using a personal computer running the LabVIEW software, a multifunction input/output board and signal conditioning circuits. The focusing procedure consists of a scanning method to find the lens bias voltage which maximizes the beam current measured on a beam stopper target, which is used as feedback for the scanning cycle. This system, as part of a wider start up and shut down automation system built for this particle accelerator, brings great advantages to the operation of the accelerator by turning it faster and easier to operate, requiring less human presence, and adding the possibility of total remote control in safe conditions.

    This study examined children's judgements and emotions associated with weight-based social exclusion using an ethnically diverse sample of one hundred and seventeen 9- and 13-year-old children. Children were interviewed about three scenarios depicting weight-based exclusion in athletic, academic, and social contexts. Children's judgements of exclusion, emotions attributed to the excluder and excluded targets, and justifications for judgements and emotions were examined. Overall, children judged weight-based exclusion to be wrong for moral reasons. However, they viewed weight-based exclusion in athletic contexts as less wrong compared with academic contexts, and they used more social-conventional reasoning to justify judgements and emotions attributed to excluders in athletic contexts compared with academic and social contexts. Children also expected excluded targets to feel negative emotions, whereas a range of positive and negative emotions was attributed to excluders. In addition, older children were more accepting of weight-based exclusion in athletic contexts than in academic and social contexts. We discuss the results in relation to the development of children's understanding of, and emotions associated with, exclusion based on weight. © 2014 The British Psychological Society.
