    Creativity is an important human quality upon which many achievements of humankind are based. Defined as the ability to produce something that is novel and useful or meaningful, it is difficult to operationalize for research. This text provides an overview of the historical and cultural context of this research. The assumption that creativity is related to psychiatric vulnerability dates back to antiquity. The modern interest in the subject stems from the romantic era and gained a scientific aura in the 19th century. In the 20th century, a further entanglement of creativity and psychopathology came about through the influence of patient artists on regular art. Psychometric, psychodiagnostic and genetic research supports a connection between creativity and psychiatric illness within the bipolar-psychotic continuum, with schizotypy/thymotypy as prototypes of creativity-related disorders. Evolutionary hypotheses link the schizophrenia paradox to a survival advantage through enhanced creative ability. The relevance of scientific research in this complex and heterogeneous area can be increased if creativity and psychopathology are further operationalized and if underlying art concepts are made explicit and placed in a broader cultural context. There is a continuing need for meaningful definitions and measures, as well as a multidisciplinary collaboration. Copyright © 2012 S. Karger AG, Basel.

    The assessment of radiation risk needs to be seen against the background of a historical development that has reversed the initial belief in a general beneficial effect of radiation to apprehension and fear. Numerical risk estimates are, today, based on large epidemiological studies, and the observations on the A-bomb survivors are outlined as the primary source of information. Since the epidemiological findings are obtained from relatively high radiation exposures, extrapolations are required to the much lower doses that are relevant to radiation protection. The evolution of extrapolation procedures up to current attempts at mechanistic modelling is outlined, and some of the open issues are reviewed. (author)

  8. Constructing New World Views: Learning Science in a Historical Context

    Science.gov (United States)

    Becker, B. J.

    1994-12-01

    Recent research has shown that children, like scientists, can tolerate a wide range of observations that do not match their expectations, or that even directly conflict with them, without abandoning their personally constructed system of beliefs about the natural world. Traditional approaches -- even laboratory experiences that support textbook presentations of theories -- do not guarantee students will alter their convictions concerning how things "ought" to work. In contrast, a history-grounded approach to presenting scientific concepts has the potential for doing precisely that. In this paper, the author argues that embedding science learning in a historical context engages students in thinking about science in a way that complements and enriches a "hands-on" approach to inquiry learning. It conveys the creative and very human character of scientific explanation -- its tentative, probabilistic, and serendipitous nature. By integrating well-chosen historical images and ideas into traditional content-centered science units, educators can stimulate productive classroom discussion and establish a classroom atmosphere that nurtures students to think critically about the meaning of scientific activity in different cultures and times More importantly, the use of historic episodes in teaching science opens up opportunities for students to identify their own untutored beliefs about the workings of the natural world, to examine them critically in the light of considered historical debate, and to confront these beliefs in a way that results in positive, long-lasting conceptual change.

    It is rare to find anything written about hearing loss or its treatment in either representative art or in a medicalhistorical context in ear, nose and throat journals. Examples dating back over the past 4000 years found in medical-historical, philosophical, and literary documents are presented and commented on. The ancient Egyptians and Greeks attempted to explain deafness and sought remedies,making use not only of empiric rational means but also magic and religion. Later, in the Middle Ages, examples from Christian iconography are found demonstrating miracle healing of deafness.Education of the deaf was not considered possible from the time of Aristotle to the sixteenth century, but from then on was organized on a large scale utilizing speech with gestures.

    The passage of the Medicare Access and CHIP Reauthorization Act (MACRA) replaces the sustainable growth rate with a payment system based on quality and alternative payment model participation. The general structure of payment under MACRA is included in the statute, but the rules and regulations defining its implementation are yet to be formalized. It is imperative that the radiology profession inform policymakers on their role in health care under MACRA. This will require a detailed understanding of prior legislative and nonlegislative actions that helped shape MACRA. To that end, the authors provide a detailed historical context for payment reform, focusing on the payment quality initiatives and alternative payment model demonstrations that helped provide the foundation of future MACRA-driven payment reform.

  12. The Historical Context of the 2017 Hurricane Season's Ocean Warmth

    2017-12-01

    Public discussion of the unusually active 2017 North Atlantic Hurricane Season quickly focused on the role of sea surface temperatures (SSTs) in the North Atlantic. Some meteorologists characterized them as near-normal, while climate-focused voices tended to characterize them as warmer than average, placing them in the context of anthropogenic warming. Much of this divergence in views can be explained by the relatively recent, relatively warm baseline (1981-2010) used for daily SST information, such as provided by OISSTv2. Longer term records of SSTs, such as HadISST, HadSST, and ERSST only attempt to provide monthly averages, while tropical cyclones have lifetimes on the timescale of days. Further, hurricanes create a cold wake which can impact storm movement and intensity, as well as subsequent storms, but is gradually wiped out by the sun. This process is further complicated by the role of ocean heat content (OHC), an increase in which can mitigate the impact of upwelled water. Here we examine the statistical characteristics of daily SSTs and OHC during the satellite record, including their temporal autocorrelation, and use this information in conjunction with longer term monthly records to bound what we can and cannot confidently say about the longer term historical context of the storms Harvey, Irma, and Maria.

El fenómeno puede caracterizarse como un paso más en la elección de estilos de vida propios de las sociedades contemporáneas, y como uno de los más importantes ensayos de libertad de circulación internacional y de ejercicio de los derechos de la ciudadanía de todos los europeos. Este texto quiere ahondar en aspectos de la interacción social y la relación antropológica de los nuevos residentes y la población autóctona, también europeos; a la vez que hacerse eco de las diversas actitudes críticas que este experimento social despierta en las ciencias sociales. Y va a procurar hacerlo ubicándolo en el contexto de las relaciones históricas de España y Europa y de cierta desesperanza que provoca la situación de crisis mundial que vivimos.Abstract: In the first decade of this century, Spain, which already had a long trajectory as an exceptional tourist destination, prepared to receive a deluge of people from North and Central Europe, who chose our country as their place of residence.

    The authors discuss the evolution of the evaluation and management of colonic trauma, as well as the debate regarding primary repair versus fecal diversion. Their evidence-based review covers diagnosis, management, surgical approaches, and perioperative care of patients with colon-related trauma. The management of traumatic colon injuries has evolved significantly over the past 50 years; here the authors describe a practical approach to the treatment and management of traumatic injuries to the colon based on the most current research. However, management of traumatic colon injuries remains a challenge and continues to be associated with significant morbidity. Familiarity with the different methods to the approach and management of colonic injuries will allow surgeons to minimize unnecessary complications and mortality. PMID:24294119

This is partly explained by the fact that the philosophy of the concept of guilt tried to give the followers of different schools of thought and jurisprudence in the concept of guilt is different in each area of law. That is why it is important to identify common features of the legal and philosophical category of "guilt".The purpose of this study to trace the evolution of the concept of guilt in the philosophy and theory of law.Scientific and practical significance of the work lies in the fact that comprehensive studies of this nature brings us closer to the development of a unified concept of guilt.The author uses an analytical, philosophical and comparative - historical methods.The article analyzes the evolution of the concept of guilt in a historical context. The author analyzes the legal significance of the concept of guilt in theology and philosophy, focusing on Russian philosophy and Marxism, and comes to the conclusion that the issue of guilt is recognized by all philosophies, the most consistent explanation of the fault is given in the idealist doctrine. In the understanding of guilt there is dualism, which leads to the need for the external and internal sides of human actions.The results of this study provide scientific and practical value, since they can be used in teaching students of legal and philosophical disciplines, as well as - a legislator, in the formulation of the concept of a single fault in the law.DOI: http://dx.doi.org/10.12731/2218-7405-2013-10-19

    Full Text Available This report will trace the development of the historical earthquake catalog of the Philippines, assess its present state and recommend future research directions. The current Philippine historical earthquake catalog is culled from various catalogs, both global and local, that were developed since the first Philippine catalog by Perrey was published in 1860. While early global catalogs gave simple mention of earthquakes in the Philippines, more focused earthquake catalogs about the Philippines gave more explicit descriptions of earthquake accounts and adopted descriptions by local historians. Over the years, various historians and seismologists continued to compile their catalogs whose contents depended on the author?s perspectives and purposes. These works varied from simple listings to others including detailed descriptions. It was only recently that an attempt made to parameterize the magnitudes and epicenters of Philippine historical earthquakes using magnitude-felt area relations was done. A more detailed catalog, however, is now underway that will show details of intensity distribution for each significant historical earthquake. By comparing the historical catalog with the recent catalog and assuming that the recent catalog is complete, we find that there are still a substantial amount of historical earthquakes that needs to be reviewed and located. Possible sources of new information are local libraries, museums and archives in the Philippines, Spain and other Southeast Asian countries to which the country was in contact with during historical times.

    Using cross-sectional data for 76 countries, we apply instrumental variable techniques based on pronoun drop, temperature and monarchies to demonstrate that historical trust levels predict several indicators of current welfare state design, including universalism and high levels of regulatory...... freedom. We argue that high levels of trust and trustworthiness are necessary, but not sufficient, conditions for societies to develop successful universal welfare states that would otherwise be highly vulnerable to free riding and fraudulent behavior. Our results do not exclude positive feedback from...... welfare state universalism to individual trust, although we claim that the important causal link runs from historically trust levels to current welfare state design....

    Full Text Available Ancient treasuries promoted wealth and prosperity of the donation community. Preserved relief scenes portrayed mythological stories used for expressing certain characteristic reflection of reality (chaos, wilderness, heroism, etc. By analyzing historical sources is possible to assign events related to the poleis in historical context. This paper shall serve as introduction of hypothetical nature of political program and contribution to the knowledge of political promotion of polis in relief decoration. Figural decoration became a form of political program, or even metaphorical ideology. The main carrier of ideological reference were figure decorated pediments and friezes. Those visualized political agenda of polis even for illiterate observers. In particular mythological stories, those that might have some ideological scheme, were preferred. They can be applied to current events of polis, but only if adequate historical sources or archaeological evidence. Mythological battles were frequent motifs. The story of Gigantomachy allowed various kind of exploitation in political ideology. The main idea was the battle between world full of chaos and world representing stability and certainty. Analogies are identifiable in the whole archaic period. The main inspiration were military confrontations with other Greek or non-Greek cities. From preserved decorative elements is possible to roughly characterize also political significance of mythological heroes. Visual display is closely related to foreign policy and inner political conflict of poleis. It is important that preserved reliefs with motives that do not deal with panhellenic scenes are lessnumerous.

Additionally, this paper considers the historical events that have shaped the conditions, bureaucracies, and interactions of urban institutions. When the findings from these urban science education studies were consolidated with the historical overview provided, it was revealed that the basic design and regulatory policies of urban schools have not substantively changed since their establishment in the nineteenth century. Teachers in urban science classrooms continue to face issues of inequality, poverty, and social injustice as they struggle to meet the needs of an increasingly diverse student population. Furthermore, persistent concerns of conflicting Discourses, cultural dissonance, and oppression create formidable barriers to science learning. Despite the many modifications in structure and organization, urban students are still subjugated and marginalized in systems that emphasize control and order over high-quality science education.

    Various types of psychology have come into existence in and have been interacting with a plurality of contexts, contexts that have been radically varying in different states or nations. One important factor in the development of psychology has been the multiple relationships to the Christian religion, whether understood as an institution, a worldview, or a form of personal spirituality. The articles in this issue focus on the intertwinements between institutional religion and national political structures and on their influence on developing forms of psychology in four different national contexts: Spain, the Netherlands, the United Kingdom, and the United States. Within these four settings, aspects of the ways in which varying forms of Christian religion coconstituted, facilitated, and shaped psychology, theoretically, practically, and institutionally, are examined. The formative power of the religions was not independent of the relationships between religion and political power, but rather mediated by these.

    This document was prepared to support u.s. Department of Energy / National Nuclear Security Agency (DOE/NNSA) compliance with Sections 106 and 110 of the National Historic Preservation Act (NHPA). Lawrence Livermore National Laboratory (LLNL) is a DOE/NNSA laboratory and is engaged in determining the historic status of its properties at both its main site in Livermore, California, and Site 300, its test site located eleven miles from the main site. LLNL contracted with the authors via Sandia National Laboratories (SNL) to prepare a historic context statement for properties at both sites and to provide assessments of those properties of potential historic interest. The report contains an extensive historic context statement and the assessments of individual properties and groups of properties determined, via criteria established in the context statement, to be of potential interest. The historic context statement addresses the four contexts within which LLNL falls: Local History, World War II History (WWII), Cold War History, and Post-Cold War History. Appropriate historic preservation themes relevant to LLNL's history are delineated within each context. In addition, thresholds are identified for historic significance within each of the contexts based on the explication and understanding of the Secretary of the Interior's Guidelines for determining eligibility for the National Register of Historic Places. The report identifies specific research areas and events in LLNL's history that are of interest and the portions of the built environment in which they occurred. Based on that discussion, properties of potential interest are identified and assessments of them are provided. Twenty individual buildings and three areas of potential historic interest were assessed. The final recommendation is that, of these, LLNL has five individual historic buildings, two sets of historic objects, and two historic districts eligible for the National Register. All are

    Dore, C.; Murphy, M.

    2017-08-01

    In an extensive review of existing literature a number of observations were made in relation to the current approaches for recording and modelling existing buildings and environments: Data collection and pre-processing techniques are becoming increasingly automated to allow for near real-time data capture and fast processing of this data for later modelling applications. Current BIM software is almost completely focused on new buildings and has very limited tools and pre-defined libraries for modelling existing and historic buildings. The development of reusable parametric library objects for existing and historic buildings supports modelling with high levels of detail while decreasing the modelling time. Mapping these parametric objects to survey data, however, is still a time-consuming task that requires further research. Promising developments have been made towards automatic object recognition and feature extraction from point clouds for as-built BIM. However, results are currently limited to simple and planar features. Further work is required for automatic accurate and reliable reconstruction of complex geometries from point cloud data. Procedural modelling can provide an automated solution for generating 3D geometries but lacks the detail and accuracy required for most as-built applications in AEC and heritage fields.

    Full Text Available Abstract Background There is evidence of a contribution of early life socioeconomic exposures to the risk of chronic diseases in adulthood. However, extant studies investigating the impact of the neighborhood social environment on health tend to characterize only the current social environment. This in part may be due to complexities involved in obtaining and geocoding historical addresses. The Life Course Socioeconomic Status, Social Context, and Cardiovascular Disease Study collected information on childhood (1930–1950 and early adulthood (1960–1980 place of residence from 12,681 black and white middle-aged and older men and women from four U.S. communities to link participants with census-based socioeconomic indicators over the life course. Results Most (99% participants were linked to 1930–50 county level socioeconomic census data (the smallest level of aggregation universally available during this time period corresponding to childhood place of residence. Linkage did not vary by race, gender, birth cohort, or level of educational attainment. A commercial geocoding vendor processed participants' self-reported street addresses for ages 30, 40, and 50. For 1970 and 1980 censuses, spatial coordinates were overlaid onto shape files containing census tract boundaries; for 1960 no shape files existed and comparability files were used. Several methods were tested for accuracy and to increase linkage. Successful linkage to historical census tracts varied by census (66% for 1960, 76% for 1970, 85% for 1980. This compares to linkage rates of 94% for current addresses provided by participants over the course of the ARIC examinations. Conclusion There are complexities and limitations in characterizing the past social context. However, our results suggest that it is feasible to characterize the earlier social environment with known levels of measurement error and that such an approach should be considered in future studies.

    Full Text Available The study analyses the historical development of vocational literacy in basic education and Non-Formal Vocational Education (NFVE in Mozambique, as well as current challenges and contradictions. The theoretical lens of Cultural-Historical Activity Theory (CHAT is employed in the study. Methodologically the study was executed through an analysis of oral, printed and e-resources produced by the main stakeholders and also the reflective experiences of the authors in their extensive educational work in the country. The findings reveal poorly developed vocational literacy education in schools and non-formal settings in spite of recurrent political declarations about its importance. There is a strong dependence by formal and particularly NFVE sectors on the technical and financial support provided by international organisations. Vocational literacy courses are characterized by a lack of adequate equipment and poor practice. As a consequence, theoretical or elementary forms of vocational knowledge are dominant in the courses, resulting in the dissatisfaction of both learners and educators. Vocational literacy development proved to be a complex field that faces many challenges and ischaracterised by diverse internal contradictions.

  19. Alberta's oil sands fiscal system : historical context and system performance

    International Nuclear Information System (INIS)

    2007-01-01

    This report described the fiscal system applied to Alberta's oil sands. It is the first technical report forming part of a series designed to provide information and to invite comment as part of the Government of Alberta's public review of the fiscal system applied to the province's oil and gas resources. Specifically, this report assessed the robustness of Alberta's oil sands fiscal system and assessed how the regime balanced the risks and rewards to both investors and Albertans across a range of expected and probable economic outcomes. The report provided an explanation of the history and context of Alberta's royalty regime and included a case-by-case approach. It also provided a discussion of the oil sands fiscal system description. Next, it described the methodology employed for the analysis of the oil sands fiscal system. It also provided the assumptions for 5 scenario cases and presented the fiscal map approach for assessing project economics and fiscal system performance. Last, summary observations were presented. It was found that the oil sands fiscal system is very flexible for adverse economic conditions and much less so for highly profitable conditions. tabs., figs

    McCool, W F; McCool, S J

    1989-01-01

    Despite the fact that the profession of nurse-midwifery and feminism are both disciplines concerned with women and issues affecting women's lives, there has been little investigation or acknowledgement of relationships between their two paradigms. The work presented here is an attempt to discover both similarities and differences between nurse-midwifery and feminist thought. Using a historical approach, it is shown that despite the common goal of improving and maintaining women's status in the world, whether in general or more specifically with regard to health, feminist theorists and nurse-midwives, to a large degree, have worked separately from each other, rarely acknowledging in any formal way the importance of the other discipline. Current issues that have an effect on the practice of nurse-midwifery today--lay midwifery, the profession of nursing, and nurse-midwifery research--are presented in relation to contemporary feminist thought.

  2. Abortion in context: historical trends and future changes.

    Science.gov (United States)

    Rossi, A S; Sitaraman, B

    1988-01-01

    Reform of abortion laws in the United States stemmed from concern over the health consequences of illegal abortion. Feminists were relative latecomers to the movement, and abortion did not become a major political issue until after the Roe v. Wade decision by the Supreme Court. Most social scientists began to study public attitudes toward abortion, which have been relatively stable since that 1973 decision, only after the Supreme Court ruling, and they thus probably missed documenting the period in which the major attitudinal changes occurred. Polls showed that the American public is most likely to approve of abortion when there is a fetal defect and when the pregnancy endangers maternal health or is the result of rape. These single reasons do not seem to jibe with the complexities of real life, however: The majority of women who have abortions indicate more than one reason for doing so, and the major reasons given concern the conflicting responsibilities of school, work and family and an inability to afford another child. A view of the abortion controversy that puts it into a larger context than do most polls and most American research suggests that legal abortion in the United States is unlikely to be jeopardized in the long run. The trend in most Western industrial nations is toward a more secularized society that features more individual discretion and less control by religious and political institutions over private aspects of life. In the immediate future, a number of factors will perpetuate the need for access to abortion. Among them are early sexual activity that often results in pregnancies among very young women; dim prospects for innovative technological advances in the contraceptive field; and the AIDS epidemic, which may result in the use of contraceptives that are more effective against that deadly virus but less effective at preventing pregnancy. Nor will abortion decisions become any easier for the families and individuals involved, as technology

  5. Gambling in China: socio-historical evolution and current challenges.

    Science.gov (United States)

    Wu, Anise M S; Lau, Joseph T F

    2015-02-01

    This paper provides an overview of gambling issues in China, including historical development, governmental responses and social consequences. Based on materials written in Chinese or English available at academic databases and other online resources, historical, cultural and policy analyses were conducted. The focus is on mainland China, but reference is made to Hong Kong and Macao to illustrate differences. Throughout Chinese history, gambling was strictly prohibited by law. In contrast, small-stakes betting for entertainment instead of monetary gain, defined as 'gaming' in this paper, has been culturally acceptable and tolerated by governments. After banning gambling for three decades, the Chinese government attempts to meet public demand for 'gaming' and to confine gambling to 'gaming' by issuing national lotteries. In response to increased economic wealth, gambling opportunities were allowed to develop, but were restricted to Macao. Social problems such as illegal and youth gambling are, however, emerging. The 'gaming' perception may predispose Chinese individuals to wagering activities and increase the risk of gambling disorder, which has been widely seen as misconduct rather than a mental disorder. Currently, the country has a dearth of gambling research and limited prevention and rehabilitation services, almost none at national level. A distinction between small-stakes 'gaming' and large-stakes 'gambling', which has cultural roots, plays an important role in relevant governmental policies and social responses in mainland China. Gambling disorder prevention and treatment is not yet on the national agenda. The country's knowledge and services gaps on gambling problems need to be filled out. © 2014 Society for the Study of Addiction.

  6. Estimated Historical and Current Nitrogen Balances for Illinois

    2001-01-01

    Full Text Available The Midwest has large riverine exports of nitrogen (N, with the largest flux per unit area to the Mississippi River system coming from Iowa and Illinois. We used historic and current data to estimate N inputs, outputs, and transformations for Illinois where human activity (principally agriculture and associated landscape drainage have had a dominant impact. Presently, ~800,000 Mg of N is added each year as fertilizer and another 420,000 Mg is biologically fixed, primarily by soybean (Glycine max L. Merr.. These annual inputs are greater than exports in grain, which results in surplus N throughout the landscape. Rivers within the state export approximately 50% of this surplus N, mostly as nitrate, and the remainder appears to be denitrified or temporarily incorporated into the soil organic matter pool. The magnitude of N losses for 1880, 1910, 1950, and 1990 are compared. Initial cultivation of the prairies released large quantities of N (~500,000 Mg N year�1, and resulted in riverine N transport during the late 19th century that appears to have been on the same order of magnitude as contemporary N losses. Riverine flux was estimated to have been at a minimum in about 1950, due to diminished net mineralization and low fertilizer inputs. Residual fertilizer N from corn (Zea mays L., biological N fixed by soybean, short-circuiting of soil water through artificial drainage, and decreased cropping-system diversity appear to be the primary sources for current N export.

    Full Text Available This contribution presents the methods of research and filing of the historical data which are at the basis of the Catalogue of Strong Italian Earthquakes (CFTI3. Seen from the point of view of historical research, this is the first research carried out in Italy with continuous methods and objectives exceeding 15 years. Here the basic, historical and scientific sources that were used are presented, considering the peculiarity of these sources in relation to the testimonies of the seismic effects. In total, there are 25 780 recorded and analysed bibliographical entries, which have disclosed and located 33 150 seismic effects from the ancient world till 1997. The basic work has not only consisted of a meticulous indexing of the sources and texts, but also of a new outlining of the particular historical and cultural contexts, in which 605 analysed strong earthquakes occurred. Moreover, a small historical guide is presented to help orientate the user of the CFTI3. The complex history of the present-day Italian territory (which has passed for centuries under very different dominations and institutional structures has demanded a non-superficial analysis of these contexts in order to better trace and interpret the testimonies of the seismic effects on buildings as well as on the natural environment. The work, carried out with groups of specialised researchers, has also led to the compiling of a database capable of dynamically managing the interpreted information. The open structure of this work allows for the continuous data updating and expansion.

  12. Science and Society: Public History in the Context of Historical Culture of the Globalization Era

    Directory of Open Access Journals (Sweden)

    Lorina P. Repina

    2015-12-01

    Full Text Available In the XIX century known as the „historical age”, a high degree of trust to history and social prestige of historical science relied on the entrenched in public consciousness the idea of continuity of historical development of a human civilization and, respectively, of the unique opportunities of the use of the past experience as a means to solve the problems of the present and to build „the bright future”. But the understanding of the dramatic experi-ence of the XX century undermined the belief in the “use of history”, and this situation has been greatly aggravated with intensification of the processes of globalization on the bor-der of XX and XXI centuries. The problems of interaction between “academic (professional history” and the wide public in the concrete societies and the changes in their relations in the context of deep social transformations proved to take place at the center of many re-searchers’ attention. Public history is purposefully overcoming the typical for historical science of the XX century alienation from „the uninitiated”; it strives to restore the interest of the consumer to the historians’ production, to propagate professional standards, histor-ical knowledge and proper understanding of the specific character of “historian’s craft” among the wide circles of the non-professionals.

  13. Arctic development and historical analysis: the use of historical methodology in addressing current issues in the Arctic.

    Douglas, Vasiliki Kravariotis

    2008-06-01

    To demonstrate the applicability of historical methodology to current issues in the Canadian Arctic. This is a literature-based analytical historical study, which draws on material from database searches of MEDLINE, Anthropology Plus, POLARInfo, the Arctic Blue Books and Historical Abstracts. Material was also obtained from physical searches of the University of Alberta Libraries and Library and Archives Canada collections, as well as from field research in the records of the Inuulitsivik Maternities. The historical technique of tracing epistemological change over time, pioneered by Michel Foucault and further developed by Ian Hacking, was applied to the history of Canadian authority in the Arctic. This was linked with epistemological changes occurring throughout Western/Southern culture in this period. The applicability of this historical analysis for current issues in the region was then evaluated. An epistemological shift in Western society has moved authority from traditional human actors in government, medicine and, increasingly, science to statistics, which is seen as both impartial and accurate. Human authorities now routinely appeal to statistical authority to validate policy decisions. This change is as apparent in the Arctic as elsewhere, but it has also opened a space for Inuit practices, rooted in traditional Inuit epistemology, to reassert themselves, provided they can satisfy demands for statistical validity. Historical analysis provides a means to identify the spaces which epistemological change and historical contingency have opened in which social and cultural change can occur.

  16. Coming-out across the life course: implications of age and historical context.

    2006-06-01

    Effects of age and the calendar year when individuals first self-identified as gay, lesbian, or bisexual on their sexual orientation identity development were examined in a large community sample (N=767, 47% female, 18-74-years-old). These 2 variables were used to examine the timing and sequencing of 7 coming-out experiences: first awareness of same-sex attraction; first sexual experiences with opposite-sex partners; first sexual experiences with same-sex partners; self-identification as gay, lesbian, or bisexual; disclosure to someone other than a parent; disclosure to mother; and disclosure to father. The significant effects of age revealed that self-identification in adolescence as opposed to adulthood was associated with an overall young coming-out trajectory for all milestone experiences, which occurred in both earlier and recent historical contexts. Adolescents as opposed to adult self-identifiers were also more likely to demonstrate identity-centered sequences in which self-identification preceded same-sex sexual experiences, and fewer of these individuals had any heterosexual experience. Significant historical context effects indicated recent trends toward younger disclosure of orientation to others and to parents, greater likelihood of an identity-centered sequence, and younger ages for first heterosexual but not same-sex, sexual experiences. Among women, there was a recent trend toward greater likelihood of having a bisexual identity milestone. In general, the maturational effects were independent of historical context, with the exception that only adolescent self-identifiers who came out recently disclosed to others and to parents at an average age younger than 18 years. These developmental and historical trends expand on the stage-sequential framework to show how the process of sexual orientation identity development is driven by maturational factors as well as social changes.

    The history of the temperament concept begins in ancient Greece. The humoral theory remained influential over the centuries. At the beginning of the 20 th century, both Wilhelm Wundt and his pupil Emil Kraepelin formulated new aspects. Wundt described two dimensions: "speed of variability of emotions" and "intensity of emotions". Kraepelin observed four fundamental states (depressive, manic, irritable and cyclothymic), which he linked to manic-depressive illness. Since then different lines of temperament research have evolved: (1) psychiatric-psychopathological theories (e. g. Ewald, Kretschmer and Sheldon), which tend to see temperament as a dilution of full-blown affective disorders; (2) neurobiological theories (e. g. Pavlov, Eysenck and Gray), which understand temperament as determined by underlying neurobiological processes - especially levels of arousal; and (3) developmental theories (e. g. Chess & Thomas, Rothbart and Kagan), which derived their temperament concept from early childhood observations. Recent theories (e. g. those of Cloninger or Akiskal) combine different aspects. After reviewing the historical temperament concepts we present underlying factors which are linked to affective disorders (such as emotional reactivity, cyclicity or trait affectivity). Finally, we illustrate the importance of temperament concepts for research in affective disorders.

    2016-03-01

    Ethnicity and cultural experience can affect neuropsychological performance, but they are rarely assessed in historical context. Attention measures are considered strongly biologically determined and therefore potentially culture-fair. In this study, we assessed the cross-cultural equivalence of Spanish and English versions of the Trail Making Test (TMT; Reitan, 1958, Perceptual and Motor Skills, 8, 271-276) and the Brief Test of Attention (BTA; Schretlen et al., 1996, The Clinical Neuropsychologist, 10, 80-89) in two large samples of Americans (N = 203) and Spaniards (N = 213), divided into younger and older subgroups. The older Spaniards lived under Franco's political regime (1936-1975), whereas the Americans never experienced such repression. Overall, TMT performance was culture-sensitive, whereas BTA performance was not. However, when both groups were stratified by age, cultural differences in TMT performance were restricted to older participants, suggesting that historical experience across generations might have contributed to the observed differences in cognitive performance. Even such basic cognitive processes as attention, working memory, and resource sharing might be shaped to some degree by historical experiences that contribute to cultural differences. © 2015 The Authors.

    The evolution and development of opinions on the diagnosis and treatment of breast cancer since Galen to present time is presented. The concept of breast cancer as a local disease has been replaced by the understanding of its systemic character. On this background described are the methods of surgical treatment beginning from early - supraradical, to present -conservative approaches. The ''milestones'' in diagnosis and treatment of breast cancer of the last 40 years are presented. Current methods of breast cancer management include correct diagnosis (clinical examination, mammography, ultrasound, fine needle aspiration biopsy), TNM staging, adequate loco-regional therapy, systemic therapy, rehabilitation, reconstruction and careful follow-up.

    The discovery of evolutionarily conserved Atg genes required for autophagy in yeast truly revolutionized this research field and made it possible to carry out functional studies on model organisms. Insects including Drosophila are classical and still popular models to study autophagy, starting from the 1960s. This review aims to summarize past achievements and our current knowledge about the role and regulation of autophagy in Drosophila, with an outlook to yeast and mammals. The basic mechanisms of autophagy in fruit fly cells appear to be quite similar to other eukaryotes, and the role that this lysosomal self-degradation process plays in Drosophila models of various diseases already made it possible to recognize certain aspects of human pathologies. Future studies in this complete animal hold great promise for the better understanding of such processes and may also help finding new research avenues for the treatment of disorders with misregulated autophagy.

    2018-03-01

    Full Text Available The contract underwent several changes from Roman law to the current civil law. These transformations are felt in the study of contractual theory, especially of principles, which reflect the influence of the social-historical context on the legal design of the institute. The present article aims to make a study of the main contractual principles of the present civil law, from the historical-social moment of its emergence and from a dynamic perspective, contemplating the reflexes of the social-historical changes in these principles. To do so, it starts with the contract as a source of obligations in Roman law, passing through the so-called classic contract, the rise of contractual freedom, until arriving at the current contractual model, in which the so-called social principles emerge and coexist together.

    Clinical pharmacology in Russia has long history and is currently active, but rather unrecognized internationally. It is governmentally approved as a teaching/scientific specialty since 1983 and as a medical specialty since 1997. Courses of clinical pharmacology are included in the undergraduate curricula in the 5th and/or 6th year of education at all medical schools in the Russian Federation. Postgraduate education includes initial specialization in internal medicine with further residency in clinical pharmacology. Governmental legislation recommends that every healthcare institution has either a department or a single position of clinical pharmacologist. Major routine duties include information about and monitoring of medication use, consultations in difficult clinical situations, pharmacogenetic counseling, therapeutic drug monitoring, pharmacovigilance, and participation in drug and therapeutics (formulary) committees. There are official experts in clinical pharmacology in Russia responsible for coordinating relevant legislative issues. The chief expert clinical pharmacologist represents the discipline directly at the Ministry of Health. Research in clinical pharmacology in Russia is extensive and variable, but only some of it is published internationally. Russia is a participant of international societies of clinical pharmacology and therapeutics and collaboration is actively ongoing. There are still certain problems related to the development of the discipline in Russia-some healthcare institutions do not see the need for clinical pharmacology. However, the number of clinical pharmacologists in Russia is increasing as well as their role in physicians' education, national healthcare, and research.

    Full Text Available This paper analyzes the urban edges of historic cities. Managing these edges would enhance the success of any intervention projects inside the historic fabric. The paper develops and tests a method of analytical assessment framework that is applicable for quantitative analysis within an urban edge. It is capable of measuring micro and macro levels of analysis of historic urban edges with reference to their spatial configuration. In addition, the paper searches for repetitive spatial configuration patterns. The main case study is Historic Cairo. The paper reveals that there are apparent patterns of cause and effect of both spatial configurations and related activities along the urban edges, forming different type of barriers. The paper discovers the repetitive spatial, architectural, and land-use patterns that exist on various edges. These patterns enable the possibility of learning and acquiring from other successful interventions that have been applied to similar patterns, without being limited to cultural or contextual differences.

    Full Text Available Financial crisis determined the fast extension of global financial bankruptcy upon the world, representing at the same time the first crisis of the accounting term of "fair value", under the shade of which subsists a number of standards which request to the institutions to estimate at the market value much of the assets they possess. The Council for International Standards in Accountancy (IASB revised the rules regarding the accountancy at the fair value, as a reaction before the critics which sustains that the accountancy rules at the fair value were the basis of volatility of financial market. The alternative for "fair value" – the historical cost of assets – has little admirers within the financial crisis. In the pages of the present article, we will try to achieve an incursion through specialized literature while analysing the two methods of valuation within the context of financial crisis.

    Full Text Available The paper is submitted to a scientific discussion the possibility of considering the idea of political science, based on the criteria of intellectual integrity and disciplinary unity. In this context, generally accepted among professionals and political scientists idea that political science as a scientific discipline occurs in the early twentieth century and its conceptual framework is still in a state of development, and a long preceding period should be characterized as a period of political thought is being challenged. The main idea that is being proved is recognition the existence of such scientific discipline as political science requires recognition of the existence of specific inherent ideals of science, cognitive standards, rules, procedures, explanations, etc. They allow political thinkers from the ancient world as well as modern researchers to combine it into a single, unique, different from others in their methodological principles and heuristic potential Science. It is convinced that the existence of intellectual integrity and disciplinary unity in Political Science is possible due to the existence of the ideals of scholarship, which are closely related to the cultural and historical context in which Political Science is being developed. The possibility of applying such disciplinary and integrated approach is considered as an example of the impact that was made by changes of the Great French Revolution and its consequences on transformation of the conceptual framework of Political Science.  It is concluded that the consideration of the peculiarities of political thought development in the social and cultural contexts related to the events of the Great French Revolution and its consequences argues that political science is responsive to changing the social context, makes changes in categorical apparatus, introduces the new field of scientific inquiry, actualized subject field. These actions are due to the specific disciplinary unity

  13. Compromised Rivers: Understanding Historical Human Impacts on Rivers in the Context of Restoration

    Directory of Open Access Journals (Sweden)

    Full Text Available A river that preserves a simplified and attractive form may nevertheless have lost function. Loss of function in these rivers can occur because hydrologic and geomorphic processes no longer create and maintain the habitat and natural disturbance regimes necessary for ecosystem integrity. Recognition of compromised river function is particularly important in the context of river restoration, in which the public perception of a river's condition often drives the decision to undertake restoration as well as the decision about what type of restoration should be attempted. Determining the degree to which a river has been altered from its reference condition requires a knowledge of historical land use and the associated effects on rivers. Rivers of the Front Range of the Colorado Rocky Mountains in the United States are used to illustrate how historical land uses such as beaver trapping, placer mining, tie drives, flow regulation, and the construction of transportation corridors continue to affect contemporary river characteristics. Ignorance of regional land use and river history can lead to restoration that sets unrealistic goals because it is based on incorrect assumptions about a river's reference condition or about the influence of persistent land-use effects.

  14. Geology and religion - historical perspective and current problems

    Kölbl-Ebert, Martina

    2010-05-01

    Today, when referring to the relationship between geology and religion, people usually at once think of Christian (and other) fundamentalists and their chronic palaeontological illiteracy leading to Creationism, to Intelligent Design, and a distrust of science in general among them most prominently geology, palaeontology and evolutionary biology. Thus the relationship of geology and religion is usually considered to be under strain. In former times things used to be quite different, and for most of human history the observation of geological phenomena and the acquisition of geological expertise was intimately connected with religious ideas. The Judeo-Christian sense of a finite Earth history prepared the ground for accepting the Earth's different strata as testimony to the development of our globe through time. It was this religious, theological framework, from which the early geology started to evolve. However, with increasing observations there was a growing mismatch between what was expected according to ancient, scriptural authorities and the actual data. The release of geology from religious connotations or associations was a development closely connected with the Enlightenment, when geology and religion started to drift apart not with a violent rupture but in a subtle and sometimes circuitous manner. However, outside the group of people with geological expertise, not all was smooth and peaceful, and some conservative clergymen as well as laypersons were rather shocked by the new ideas that came with geology: the immensity of the timescale, a dynamic Earth, not just a ruin shaped by the Deluge, and a dynamic biology too with the Darwinian theory of evolution, which was founded in part on palaeontological evidence and the assumption of a long geological time scale. Nevertheless and interestingly the Creationism we face today is a rather recent phenomenon influenced by a number of motives, most of them philosophical and theological in nature. And so, the current

  15. Katrina in Historical Context: Environment and Migration in the U.S.

    2010-01-01

    The massive publicity surrounding the exodus of residents from New Orleans spurred by Hurricane Katrina has encouraged interest in the ways that past migration in the U.S. has been shaped by environmental factors. So has Timothy Egan's exciting book, The Worst Hard Time: The Untold Story of those who survived the Great American Dust Bowl. This paper places those dramatic stories into a much less exciting context, demonstrating that the kinds of environmental factors exemplified by Katrina and the Dust Bowl are dwarfed in importance and frequency by the other ways that environment has both impeded and assisted the forces of migration. We accomplish this goal by enumerating four types of environmental influence on migration in the U.S.: 1) environmental calamities, including floods, hurricanes, earthquakes, and tornadoes, 2) environmental hardships and their obverse, short-term environmental benefits, including both drought and short periods of favorable weather, 3) environmental amenities, including warmth, sun, and proximity to water or mountains, and 4) environmental barriers and their management, including heat, air conditioning, flood control, drainage, and irrigation. In U.S. history, all four of these have driven migration flows in one direction or another. Placing Katrina into this historical context is an important task, both because the environmental calamities of which Katrina is an example are relatively rare and have not had a wide impact, and because focusing on them defers interest from the other kinds of environmental impacts, whose effect on migration may have been stronger and more persistent, though less dramatic.

  16. Britain between the wars: the historical context of Bowlby's theory of attachment.

    Newcombe, N; Lerner, J C

    1982-02-01

    As developmental psychology "comes of age," there is increasing interest in tracing the history of thought and research concerning children (Lomax, Kagan, and Rosenkrantz 1978; Sears 1975; Senn 1975). Such an enterprise offers the possibility of providing not only a descriptive chronicle of personal or anecdotal interest, but a basis for insights into how our ideas have been shaped by the cultural context in which they were developed. It is, for instance, by now commonplace to note that much of Freud's thought should be seen in the context of 19th-century Vienna, and that many of his perceptions may have been correct for the individuals he observed although they may fail as immutable observations of human behavior in general (see, e.g., Mitchell 1974). The present paper explores the cultural and historical context of another major theorist of child development, John Bowlby. The early origins of Bowlby's theory are sought in events set in train in Britain by the First World War, and occurring during the interwar period. This may surprise readers who think of Bowlby's work as beginning with the WHO Report (Bowlby 1951) and consequently as related to the Second World War, to observations by Burlingham and Freud (1942, 1944) of children separated from their families, and to Spitz's (Spitz and Wolf 1946) work on infants in foundling homes and orphanages. But formulations in the WHO report clearly appear in Bowlby's work before World War II and are also evident in the writings of Klein (1935, 1940) and Suttie (1935), who were working on themes first drawn into focus during the first World War. In a personal interview, Bowlby identified 1929 as the time when he was first struck by the importance of separation in children's lives. Thus, this paper focuses on the effect of the "Great War" on psychoanalytic thought and, more generally, on psychiatry in Britain.

    2017-10-01

    Current policy and practice directed towards people with learning disabilities originates in the deinstitutionalisation processes, civil rights concerns and integrationist philosophies of the 1970s and 1980s. However, historians know little about the specific contexts within which these were mobilised. Although it is rarely acknowledged in the secondary literature, MIND was prominent in campaigning for rights-based services for learning disabled people during this time. This article sets MIND's campaign within the wider historical context of the organisation's origins as a main institution of the inter-war mental hygiene movement. The article begins by outlining the mental hygiene movement's original conceptualisation of 'mental deficiency' as the antithesis of the self-sustaining and responsible individuals that it considered the basis of citizenship and mental health. It then traces how this equation became unravelled, in part by the altered conditions under the post-war Welfare State, in part by the mental hygiene movement's own theorising. The final section describes the reconceptualisation of citizenship that eventually emerged with the collapse of the mental hygiene movement and the emergence of MIND. It shows that representations of MIND's rights-based campaigning (which have, in any case, focused on mental illness) as individualist, and fundamentally opposed to medicine and psychiatry, are inaccurate. In fact, MIND sought a comprehensive community-based service, integrated with the general health and welfare services and oriented around a reconstruction of learning disabled people's citizenship rights.

    Full Text Available Human occupation for several centuries was recorded in the archaeological layers of "Place d'Armes", Namur, Belgium. Preventive archaeological excavations were carried out between 1996/1997 and seven historical strata were observed, from Gallo-Roman period up to Modern Times. Soil samples from cesspools, latrines, and structures-like were studied and revealed intestinal parasite eggs in the different archaeological contexts. Ascaris lumbricoides, A. suum, Trichuris trichiura, T. suis. Taenia sp., Fasciola hepatica, Diphyllobothrium sp., Capillaria sp. and Oxyuris equi eggs were found. Paleoparasitology confirmed the use of structures as latrines or cesspit as firstly supposed by the archaeologists. Medieval latrines were not only used for rejection of human excrements. The finding of Ascaris sp. and Trichuris sp. eggs may point to human's or wild swine's feces. Gallo-Roman people used to eat wild boar. Therefore, both A. suum and T. suis, or A. lumbricoides and T. trichuris, may be present, considering a swine carcass recovered into a cesspit. Careful sediment analysis may reveal its origin, although parasites of domestic animals can be found together with those of human's. Taenia sp. eggs identified in latrine samples indicate ingestion of uncooked beef with cysticercoid larvae. F. hepatica eggs suggest the ingestion of raw contaminated vegetables and Diphyllobothrium sp. eggs indicate contaminated fresh-water fish consumption. Ascaris sp. and Trichuris sp. eggs indicate fecal-oral infection by human and/or animal excrements.

    Full Text Available The aim of this overview is to evaluate the primo vascular system research in the context of the history of meridian theory and the modern meanings of it. The 12 meridian systems were naturally presupposed in the conventional study of the meridians and acupuncture. But the excavations of Mawang-tui old documents and Sichuan Mianyang wooden puppet revealed the primordial concepts of meridians uncolored by the numerological cosmology of Han era. Further, the meridian map of horse, cow and hawk show another resemblance to the primordial type of meridians. Modern meridian theory has been challenged by the material based scientific theory and the primo vascular theory presents the most radical answer for it. It aims to reveal the anatomical entity of meridians. However, the study of primo vascular system is unexpectedly opening the new horizon of scientific integration of East and West beyond the mere searching for anatomical entity of meridians. Conclusions we have drawn from the historical reviews are, (1 the surface structure of the body reflects the physiopathological changes of inside the body, (2 by stimulating specific sites on the surface, it is possible to acquire therapeutic effects of certain symptoms, and (3 numbers and locations of meridian acupoints are variable among traditional meridian theories.

  1. The French state and the church: Socio-historical context, structural conditionality and character of laicism

    Directory of Open Access Journals (Sweden)

    Mladenović Ivica

    2014-01-01

    Full Text Available In the article, the author deals with the political and social influences of the relationship between the state and religious communities in France. The first part of the paper is an analysis of historical context and the construction (evolution of laicism in France through its local characteristics, values and social strengths, contributing to its formation. The fact that Catholic Church was one of the main legitimizing pillars of „the old regime“, permanently determined the relationship between church and state, most importantly - it’s subsequent social exclusion under the Republic. The 1789 French revolution in conjunction with the 1905 law on the Separation of church and state, up until present time, have been seen as the most important events in defining the relationship between political and religious entities in France. The second part of the paper continues in outlining the founding logic and principles of the contemporary relationship between religious communities and the French state. The article concludes in suggesting that through its persistence of a purely Laicistic model of state-church affiliation, view of the nation as a community of citizens, Weberian definition of the State, and the acceptance of the public sphere as common space in which communal interests are negated, France today represents an isolated island on the European continent.

    2007-01-01

    Review paper deals with the historical analysis of intellectual activity of some famous parasitologists working in tropics on malaria in the XIX/XX century: A. Laveran (1845-1922), R. Ross (1857-1932), P. Manson (1844-1922), B. Grassi (1854-1925), and other Nobelprize researchers: P. H. Müller (1899-1965) and J. W. von Jauregg (1857-1940). Those chief investigations are interpreted from the point of view of the so-called anthropology of knowledge based on L. Fleck's (1896-1961) philosophy and sociology of science. Parasitological investigations, especially in the field of malaria, were undertaken in the developed economically countries in answer to the social demands. It was connected with development of colonies and the needs of stabilization of epidemiological situation in tropics. To mid of the eigthies of 19th century the lack of positive effects resulted from the theoretical barriers and conservative thinking style of the European academic society. It caused that great parasitological discoveries of the etiological agents of parasitic diseases (like plasmodia, life cycle in malaria) took place behind university circles. They were done by the physicians - general practitioners--in the colony areas. Doctors A. Laveran, P. Manson and R. Ross were not restricted by traditional standards and the obliging normative concepts in the academic naturalism. Those medical men worked out a new impulse for parasitology and supported an idea based on the rule that each disease should be assigned with the materialistic biological factor (pathogen). In the years 1800-1900 the old and a new concepts were competed in the natural sciences and medicine. Near year 1900 a new way in the context of modern interpretations was brought into general use. It was proved experimentally that etiological theory of parasitic disease was more practically usuful. It resulted in the formation of the effective prophylactic theory as well as the development of research in the field of chemotherapy

    2016-08-01

    Full Text Available In 2011, Germany carried out its first census after a 20-year break. In light of the United Nations’ recommendations that countries initiate a population census at least every 10 years, the census was long overdue. Moreover, demographers had for some time been demanding a new enumeration that would enable them to place the calculation of demographic indicators on a reliable basis. With the 2011 census, Germany not only met the demand for a current population census, but also broke new ground by using a register-based approach. Unlike the Scandinavian countries, which have a long tradition of performing register-based data analyses, the linking of administrative data in Germany is restricted by the country’s legal framework. Thus, the 2011 census was an ambitious project. After contextualising the 2011 census historically, we discuss in this contribution the census’ relevance for generating central demographic data. Specifically, we compare the updated population estimates of the 1987 census to the results of the 2011 census in order to identify possible systematic sources of error that distort demographic indicators and analyses.

  9. PERSPECTIVES OF INFLATION TARGETING, IN THE CURRENT ECONOMIC CONTEXT

    Directory of Open Access Journals (Sweden)

    COROIU SORINA IOANA

    2015-04-01

    Full Text Available In the context of economic crisis, monetary policy makers are facing a number of challenges, including the selection and implementation of the best monetary policy. In this paper, we want to see if inflation targeting is or is not a solution to exit the economic crisis. If the answer is positive, then what would be the optimal level of inflation? Many central banks target an inflation rate of 2%. In this paper we intend to show that, in certain circumstances, a very low level of inflation can significantly reduce the stabilizing effects of monetary policy. A slightly higher value of inflation targeting would reduce the constraints on monetary policy, caused by the appearance of liquidity trap. The risk for the interest rates of monetary policy to achieve zero level is related to the central banks’ choise of the appropriate inflation target. We believe that an increase in the inflation target of 2% to 4% would ease monetary policy constraints arising from the liquidity trap problem. If inflation targeting is not a solution to exit the crisis, then are there other strategies that would be a better alternative? Following this analysis, no obvious alternatives were identified, so far, there is no clear reason for that to abandon inflation targeting.

    The objectives of our work are to fully exploit the historic Soviet Lunokhod data and use the results for scientific and public purposes. Unfortunately, many of the relevant operational parameters of the Lunokhods missions are lost. Modern photogrammetry is a key to solving these issues, providing analysis techniques, not available at the time of the early lunar missions. For this purpose we use special developed software, GIS tools and high-resolution LRO data [1]. Results of new image processing of historic data are part of PRoViDE project (Planetary Robotics Vision Data Exploitation) which aims to assemble a major portion of the imaging data gathered from different vehicles and probes on planetary surfaces into a unique database, bringing them into a spatial context and providing access to a complete set of 3D vision products (http://www.provide-space.eu/). Our technology of archive panorama processing allows us to recover lost information of Soviet lunar missions and study lunar landing site imagery by state-of-the-art photogrammetric techniques. Our main task is to perform lunar panoramas in measurement form based on photogrammetry and geoanalyses methods, and then involve them in more detailed morphometric analyses [2] and 3D-modeling of lunar surface based on LROC NAC image processing [3]. The results of our work are various types of new products: panoramas in different projections, updated metadata with recovering parameters, and ortho-panoramas, which can be used for quantitative geomorphology assessment based on spatial tools [4]. All data products obtained as a result of the study are to be placed into Planetary data storage which is developing as Geodesy and Cartography Node [5]. Access to archive lunar data will be organized via Geo-portal (http://cartsrv.mexlab.ru/geoportal/) using authorization service, which provided data security and user control. Planetary spatial information system can integrate various types of data for planets and their

This revision points out both the historical and ethical contexts, which conditioned the banning of Thalidomide in the early 60's, and the clinical conditions in which its therapeutic effects are used and studied today.

  12. A historical context of municipal solid waste management in the United States.

    Municipal solid waste management (MSWM) in the United States is a system comprised of regulatory, administrative, market, technology, and social subcomponents, and can only be understood in the context of its historical evolution. American cities lacked organized public works for street cleaning, refuse collection, water treatment, and human waste removal until the early 1800s. Recurrent epidemics forced efforts to improve public health and the environment. The belief in anticontagionism led to the construction of water treatment and sewerage works during the nineteenth century, by sanitary engineers working for regional public health authorities. This infrastructure was capital intensive and required regional institutions to finance and administer it. By the time attention turned to solid waste management in the 1880s, funding was not available for a regional infrastructure. Thus, solid waste management was established as a local responsibility, centred on nearby municipal dumps. George Waring of New York City organized solid waste management around engineering unit operations; including street sweeping, refuse collection, transportation, resource recovery and disposal. This approach was adopted nationwide, and was managed by City Departments of Sanitation. Innovations such as the introduction of trucks, motorized street sweepers, incineration, and sanitary landfill were developed in the following decades. The Resource Conservation and Recovery Act of 1976 (RCRA), is the defining legislation for MSWM practice in America today. It forced the closure of open dumps nationwide, and required regional planning for MSWM. The closure of municipal dumps caused a 'garbage crisis' in the late 1980s and early 1990s. Private companies assumed an expanded role in MSWM through regional facilities that required the transportation of MSW across state lines. These transboundary movements of MSW created the issue of flow control, in which the US Supreme Court affirmed the protection

    Full Text Available Arnason and Raaflaub’s edited volume, The Roman Empire in Context: Historical and Comparative Perspectives, is the fifth volume in a series entitled The Ancient World: Comparative Histories. The overarching aim of the series is to bring a comparative perspective to studies of ancient histories, and earlier titles focus either on content or geography. This is the only volume to date that focuses on a specific civilization, and Rome is of course significant enough to merit its own volume.

  14. THE IMPACT OF THE CONVERSION OF HISTORICAL COST TO CORRECTED CURRENT COST ON RETURN ON ASSETS AND EQUITY: ANALYSIS FROM DUPONT SYSTEM.

    Full Text Available Historical cost is the most used form of accounting valuation, but it does not reflect the effect of currency in time. The Theory of Corrected Current Cost, albeit with limitations, may show evidence of real and relevant accounting information of the entity. In this context, a question can be formulated: What is the impact of the conversion of historical cost to corrected current cost in return on assets and equity? In order to answer this question, the DuPont system was applied in a model company as a tool for analysis. The results showed that the return of assets at historical cost and corrected current cost were 12.11% and 3.14%, respectively, a decrease of 74.07%, and the result of the return on equity, the historical cost and corrected current cost were 20.59% and 4.96%, respectively, decreased 75.91%. Based on these variations it is observed that the impacts of the conversion of the corrected current cost were significant,confirming the importance of the adoption of this practice, whenever possible.

  15. A free church perspective on military chaplains role in its historical context

    Neil E. Allison

    2016-12-01

    Full Text Available The waning influence of Christianity in the United Kingdom’s armed forces since 1960 and the growing ignorance of personnel who have ties to a particular denomination, gave rise to a new assessment of the military chaplain in a modern and postmodern context. This article gives an overview of the practice during the two world wars and after the 1960s. It also gives an overview of the debate on the current role of the military chaplain, especially the beliefs of Herspring, Zahn, Coleman and McCormack, and eventually set up a role model from a Free Church perspective. It is shown that an operating model that is only defined in pastoral terms does not satisfy. The pastoral and spiritual definition, in terms of a liminal serving as an alternative, is suggested because it frees the chaplain to act more independent and also describes the best practice that has always prevailed in the British army.

    Wright, J.; Townsend, A.; Alexander, K.

    2005-05-01

    We compared the stonefly diversity sampled from 11 selected sites in the Gunnison River Basin over the last three years to the stonefly diversity recorded by Knight (1965) from the same or nearby sites. The 11 sites in this study were chosen from the 22 sites reported by Knight (1965) because they represented mainstem Gunnison River sites that would be predicted to experience the most alteration due to anthropogenic changes such as the construction of impoundments, differences in land use patterns, and effects from the increase in human population of the region. We have been unable to locate ten of the stonefly species that were historically found and we presume that they have gone locally extinct or have become increasingly rare. We have also found six species present today that were not historically reported from Knight (1965). Maps showing current and historical stonefly diversity and distribution have been produced using ArcGIS and analyzed with relevant geographical data to form hypotheses to account for specific changes in the stonefly fauna of the basin.

  6. Current and historical drivers of landscape genetic structure differ in core and peripheral salamander populations.

    Directory of Open Access Journals (Sweden)

    Rachael Y Dudaniec

    Full Text Available With predicted decreases in genetic diversity and greater genetic differentiation at range peripheries relative to their cores, it can be difficult to distinguish between the roles of current disturbance versus historic processes in shaping contemporary genetic patterns. To address this problem, we test for differences in historic demography and landscape genetic structure of coastal giant salamanders (Dicamptodon tenebrosus in two core regions (Washington State, United States versus the species' northern peripheral region (British Columbia, Canada where the species is listed as threatened. Coalescent-based demographic simulations were consistent with a pattern of post-glacial range expansion, with both ancestral and current estimates of effective population size being much larger within the core region relative to the periphery. However, contrary to predictions of recent human-induced population decline in the less genetically diverse peripheral region, there was no genetic signature of population size change. Effects of current demographic processes on genetic structure were evident using a resistance-based landscape genetics approach. Among core populations, genetic structure was best explained by length of the growing season and isolation by resistance (i.e. a 'flat' landscape, but at the periphery, topography (slope and elevation had the greatest influence on genetic structure. Although reduced genetic variation at the range periphery of D. tenebrosus appears to be largely the result of biogeographical history rather than recent impacts, our analyses suggest that inherent landscape features act to alter dispersal pathways uniquely in different parts of the species' geographic range, with implications for habitat management.

    Physics as a discipline in El Salvador's higher education system has struggled historically; however, since 1991, it has enjoyed a growth-friendly environment. While there are few female physicists in El Salvador, they are employed in various organizations and educational institutions, demonstrating that physics is a viable career path. El Salvador currently offers a range of opportunities for women in physics. With the support of the 5th IUPAP International Conference on Women in Physics, we will both meet the challenges and take advantage of the opportunities that face female physicists in El Salvador.

    Jäger, M; Becker, T; Wigand, M E

    2016-08-01

    Against the background of Max Weber's and Karl Jaspers' outstanding historical contributions to the conceptual development of different typologies, the importance of a psychiatric typology is examined. The term "ideal type" was introduced into social science by Weber as an analytical construct to describe and classify cultural phenomena. This concept was adopted for the psychiatric context by Jaspers who proposed to establish a typological system in the field of psychotic disturbances without an organic correlate. He emphasized the importance of the course of psychopathological symptoms for such a typological system. The concept of typology can be regarded as a promising heuristic approach in psychiatry, providing a classification system for complex psychopathological symptoms. Even though several historic typologies exist in psychopathology, their usefulness in the fields of therapy and prognosis needs to be critically assessed. Also, new typologies will have to be developed, taking into account neurobiological knowledge now available. © Georg Thieme Verlag KG Stuttgart · New York.

    The declaration of Leiden pronounces the demand to conserve pathological-anatomical collections as cultural heritage. Likewise, the Institute of Pathology of the Friedrich-Alexander-University Erlangen-Nuremberg owns macroscopic pathological-anatomical specimens reaching back over 150 years. The purpose of this work is to examine the impact, meaning, and perception of such historical preparations during the current medical curriculum. Additionally, the experiences from the renovation process can be used as a template for other institutes. All preparations were documented, photographed, and catalogued in an electronic database. During a restoration period, a series of didactically suitable specimens were professionally restored. Hereby, the help of a special course of interested students was admitted. In a second step, the specimens were integrated into the regular teaching of students in macroscopic pathology. An evaluation was carried out on two student cohorts with and without historical specimens by means of a questionnaire with 23 items and two free text fields. In total, 1261 specimens were registered covering diseases from almost the complete human body with a strong representation of the cardiovascular, urinary, gastrointestinal, and central nervous systems. Hereby, exceptional rare and untreated cases with medical relevance could be found and stepwise implemented into the curriculum. The student evaluation positively addressed that the courses became livelier and interactive. Furthermore, a more comprehensive overview and a better understanding of the macroscopic pathology were appreciated. However, more self-study time with the specimen was demanded. The authenticity of historical specimens contrasts with the tendency to carry out virtual "online" didactic methods. The stereoscopic view on often untreated and, therefore, unbiased cases enhances a skill-oriented deeper understanding of diseases. In conclusion, historical specimens regain interest and even

    Full Text Available The influence of geologic and Pleistocene glacial cycles might result in morphological and genetic complex scenarios in the biota of the Mesoamerican region. We tested whether berylline, blue-tailed and steely-blue hummingbirds, Amazilia beryllina, Amazilia cyanura and Amazilia saucerottei, show evidence of historical or current introgression as their plumage colour variation might suggest. We also analysed the role of past and present climatic events in promoting genetic introgression and species diversification. We collected mitochondrial DNA (mtDNA sequence data and microsatellite loci scores for populations throughout the range of the three Amazilia species, as well as morphological and ecological data. Haplotype network, Bayesian phylogenetic and divergence time inference, historical demography, palaeodistribution modelling, and niche divergence tests were used to reconstruct the evolutionary history of this Amazilia species complex. An isolation-with-migration coalescent model and Bayesian assignment analysis were assessed to determine historical introgression and current genetic admixture. mtDNA haplotypes were geographically unstructured, with haplotypes from disparate areas interdispersed on a shallow tree and an unresolved haplotype network. Assignment analysis of the nuclear genome (nuDNA supported three genetic groups with signs of genetic admixture, corresponding to: (1 A. beryllina populations located west of the Isthmus of Tehuantepec; (2 A. cyanura populations between the Isthmus of Tehuantepec and the Nicaraguan Depression (Nuclear Central America; and (3 A. saucerottei populations southeast of the Nicaraguan Depression.

    Smirnova E.O.,

    2016-12-01

    Full Text Available The article describes the possible application of the principles of cultural-historical approach and activity theory to the inspection of toys and play environments. A children’s playground is treated as cultural means or artifact created by adults for starting a child’s activity. In terms of cultural and historical psychology, psycho-pedagogical analysis of a playground is based on the identification of the play value level and the compliance with the objectives peculiar to the age. Analysis and design are based on the understanding of the playground as a single space, where each element has the potential for any children’s development activity — games, communication, experimentation, etc. The following criteria of psychological and pedagogical inspection are identified and well-grounded: the principle of orientation to age-related peculiarities, the principle of high play value, the principle of transparency of objects, the principle of supporting acceptable risk, the principle of taking account of visitors’ activity levels, invitation to dialogue — the principle of dialogueness. The use of these principles in the course of designing playgrounds is illustrated by examples. These show that the conceptual apparatus of cultural and historical psychology may be used not only to explain the mechanisms and forms of mental development, but also for the analysis of particular conditions of a child’s mental development and design of play environments.

    Full Text Available Industrial revolution in the late nineteenth century in Western societies was a new emerging phenomenon promising a better life for the future of humanity. However, its development and growth exposed human values to fundamental changes. The challenge shaped between the development and growth of the industry and human values spread quickly to other sections. Artificial environment were one of these sections. Before the emergence of the industrial revolution the development and growth of cities were through a ritual process and there wasn’t any challenge between the development process and values. Urban values can be categorized on three parts issues of cultural-historical values, issues of skeletal-physical values, issues of environmental perceptions values. The aim of this research is to study the challenges between the development and conservation of the urban values, raising the question that ‘what has been the position of urban values in the development of the cities of Iran?’ In spite of the fact that the historical cores of the cities are valuable, there has been no attention to the present values in the process of the urban contemporary development. The present research is of the fundamental-development research type using the interpretive-historical method by data-gathering and qualitative analyses. The research revealed that the development process was based on the identity and cultural values in the cities of Iran before the advent of modernity and since the city met the existing needs, a desired coordination was shaped between urban values and development; however, the arrival of new urban elements supported legally by the government led to ignorance of many urban values in the contemporary development.

    A historical group consisting of 35 patients with osteosarcoma was compared to a concurrent group of 23 patients. The treatment for the primary tumors differed only slghtly in the two groups. A more active approach was adopted for treatment of pulmonary metastases in the concurrent group. The percentage of patients not developing metastases and the survival rate in the historical group were approximately one half those for the concurrent group. An analysis of prognostic factors disclosed differences between the two groups as regards the size and histological type of the tumor. The results of the study cast doubt on the suitability of historical controls in current clinical trials conducted to ascertain the effectiveness of adjuvant therapy for osteosarcoma

    2008-08-20

    65 surveys were completed in 2002 to assess the current distribution of special status amphibians at the Lawrence Livermore National Laboratory's (LLNL) Livermore Site and Site 300. Combined with historical information from previous years, the information presented herein illustrates the dynamic and probable risk that amphibian populations face at both sites. The Livermore Site is developed and in stark contrast to the mostly undeveloped Site 300. Yet both sites have significant issues threatening the long-term sustainability of their respective amphibian populations. Livermore Site amphibians are presented with a suite of challenges inherent of urban interfaces, most predictably the bullfrog (Rana catesbeiana), while Site 300's erosion issues and periodic feral pig (Sus scrofa) infestations reduce and threaten populations. The long-term sustainability of LLNL's special status amphibians will require active management and resource commitment to maintain and restore amphibian habitat at both sites.

    In this paper, we present a historical overview of the science communication activities in Brazil since the nineteenth century and we analyze the current situation and its main concerns. The principal scopes and tools for science communication discussed here are the following: science centers and museums, mass media and large public events for communicating science and technology (S&T). In recent years, such activities have had a significant breakthrough in Brazil. Yet, there is still a long way to go in order to deliver a quality and extensive science and technology communication to the Brazilians as well as to achieve a suitable level of social appropriation of knowledge on S&T by the Brazilian society. Some of the main challenges that we are facing are discussed herein.

    Many recent studies have explored the effects of present and past landscape structure on species distribution and diversity. However, we know little about the effects of past landscape structure on distribution of genetic diversity within and between populations of a single species. Here we describe the relationship between present and past landscape structure (landscape connectivity and habitat size estimated from historical maps) and current genetic structure in a perennial herb, Succisa pratensis. We used allozymes as co-dominant markers to estimate genetic diversity and deviation from Hardy-Weinberg equilibrium in 31 populations distributed within a 5 km(2) agricultural landscape. The results showed that current genetic diversity of populations was related to habitat suitability, habitat age, habitat size and habitat connectivity in the past. The effects of habitat age and past connectivity on genetic diversity were in most cases also significant after taking the current landscape structure into account. Moreover, current genetic similarity between populations was affected by past connectivity after accounting for current landscape structure. In both cases, the oldest time layer (1850) was the most informative. Most populations showed heterozygote excess, indicating disequilibrium due to recent gene flow or selection against homozygotes. These results suggest that habitat age and past connectivity are important determinants of distribution of genetic diversity between populations at a scale of a few kilometres. Landscape history may significantly contribute to our understanding of distribution of current genetic structure within species and the genetic structure may be used to better understand landscape history, even at a small scale. © 2012 German Botanical Society and The Royal Botanical Society of the Netherlands.

  4. Roles of sunlight and natural ventilation for controlling infection: historical and current perspectives.

    Infections caught in buildings are a major global cause of sickness and mortality. Understanding how infections spread is pivotal to public health yet current knowledge of indoor transmission remains poor. To review the roles of natural ventilation and sunlight for controlling infection within healthcare environments. Comprehensive literature search was performed, using electronic and library databases to retrieve English language papers combining infection; risk; pathogen; and mention of ventilation; fresh air; and sunlight. Foreign language articles with English translation were included, with no limit imposed on publication date. In the past, hospitals were designed with south-facing glazing, cross-ventilation and high ceilings because fresh air and sunlight were thought to reduce infection risk. Historical and recent studies suggest that natural ventilation offers protection from transmission of airborne pathogens. Particle size, dispersal characteristics and transmission risk require more work to justify infection control practices concerning airborne pathogens. Sunlight boosts resistance to infection, with older studies suggesting potential roles for surface decontamination. Current knowledge of indoor transmission of pathogens is inadequate, partly due to lack of agreed definitions for particle types and mechanisms of spread. There is recent evidence to support historical data on the effects of natural ventilation but virtually none for sunlight. Modern practice of designing healthcare buildings for comfort favours pathogen persistence. As the number of effective antimicrobial agents declines, further work is required to clarify absolute risks from airborne pathogens along with any potential benefits from additional fresh air and sunlight.

  5. Current and historic mercury deposition to New Haven Harbor (CT, USA): Implications for industrial coastal environments

    Clark, Heather F.; Benoit, Gaboury

    2009-01-01

    This study quantifies historic and current mercury contamination in New Haven Harbor (New Haven, Connecticut, USA) through the analysis of sediment cores. The mercury concentration measured in surface sediment ranged from 320 to 1640 μg kg -1 with an average of 530 μg kg -1 . The harbor is relatively small in area (6.6 km 2 ) but displays a large range in concentrations, illustrating the important methodological issue that a large number of samples may be necessary to capture the variability in even a small area. Depth profiles of mercury reflect sedimentation over a range of 20 to 200 years and indicate a complex history of contamination. Mercury depth profiles were compared with lead, copper, cadmium, and silver concentrations and the metals generally covary. This trend indicates that the sources of mercury and heavy metals are linked and that regionally specific sources dominate the historic input of metals rather than large-scale atmospheric deposition patterns. Results also show there are large differences in absolute concentrations of metals among sites in the harbor. Differences in the abundance of Fe-rich, fine-grained sediment likely control the level of metals in various parts of the harbor. Proximity to current sources and the long, diverse industrial history of the harbor also influence the distribution pattern. All of the cores can be modeled as mixing between pre-industrial sediments and either one or two pollution endmembers. This study demonstrates the importance of riverine sources in the mass balance of mercury delivered to coastal areas and of watershed management to preserve coastal ecosystems.

  6. Psychosocial Adaptation to Disability Within the Context of Positive Psychology: Philosophical Aspects and Historical Roots.

    Livneh, Hanoch; Martz, Erin

    2016-03-01

    The purpose of this article is to review the conceptual and clinical similarities that exist between the principles of positive psychology and those underlying rehabilitation counseling and psychology, occupational rehabilitation, and those espoused by the field of psychosocial adaptation to chronic illness and disability (CID). Three themes were selected for review. These included the historical contributions of early scholars in the area of psychosocial adaptation to CID that later were indirectly infused into mainstream positive psychology; state and trait constructs that constitute much of the infrastructure of positive psychology and psychosocial adaptation to CID; and, finally, the philosophical congruencies between positive psychology and psychosocial adaptation to CID. The existing literature indicates that there is a substantial philosophical and conceptual overlap between the fields of positive psychology and psychosocial adaptation to CID. Since theoreticians and researchers, from both fields, often use differing terminology and definitions to describe similar concepts, as well as seek similar research goals, it would behoove both fields to seek a closer partnership in order to establish a meaningful dialogue that focuses on human strengths and virtues in the lives of people with CID.

  7. The Administration of Tibetan Precious Pills: Efficacy in Historical and Ritual Contexts.

    2015-01-01

    Precious pills represent a special kind of Tibetan drug that once was, and still is, highly sought after by Tibetan, Chinese, and Mongolian patients. Such pills are generally taken as a potent prophylactic remedy, and can be used to cure various diseases. The present study seeks to discuss the dispensation and efficacy of precious pills according to the presentations of historical Tibetan medical scholars. Several treatises dealing with these instructions will be analysed, thereby revealing their underlying concepts, and highlighting their points of both general consensus and disagreement. The analysis of these detailed instructions will reveal the fact that these precious pills were not merely given to a patient but, in order to ensure their full efficacy, involved an elaborate regimen concerning three chronological periods: (1) the time of preparation, (2) the time of dispensation, and (3) the time after dispensation. Thus the present study surveys not only the ritual empowerment of drugs in Tibetan medicine, but also the importance of social relationships between doctors and patients in Tibetan medical history.

    This article provides an overview of the historical arguments surrounding reproductive health policy and current policy initiatives. Because reproductive policy itself is a vast subject matter with sometimes blurry boundaries, the struggle concerning the advent of birth control is used to illustrate the historic complexities of policy affecting such a wide array of individuals. The battle over introduction of the birth control pill is pertinent because the very same arguments are used today in debates over reproductive health policy.

    Analyzing people's decisions can reveal key variables that affect their behaviors. Despite the demonstrated utility of this approach, it has not been applied to livelihood decisions in the context of conservation initiatives. We used ethnographic decision modeling in combination with qualitative comparative analysis (QCA) to examine the herding decisions of Maasai households living near Tarangire National Park (TNP) during recent and historical droughts. The effects of the establishment of TNP on herding practices during drought were different than anticipated based on the size and reliability of several prominent resource areas that are now within the park. We found little evidence of people relying on these swamps and rivers for watering cattle during historical droughts; rather, these sites were more commonly used as grazing areas for small stock and wet-season grazing areas for cattle to avoid disease carried by calving wildebeest. Yet during the 2009 drought, many herders moved their livestock - especially cattle from outside of the study area - toward TNP in search of grazing. Our analysis of herding decisions demonstrates that resource-use decisions are complex and incorporate a variety of information beyond the size or reliability of a given resource area, including contextual factors (e.g., disease, conflict, grazing) and household factors (e.g., social capital, labor, herd size). More broadly, this research illustrates that pairing decision modeling with QCA is a structured approach to identifying these factors and understanding how opportunities, constraints, and perceptions influence how people respond to changes in resource access.

The aim of the proposed itinerary is to organize its specific fruition as well as the preservation of their environmental and historic heritage.

  12. Measuring retrograde autobiographical amnesia following electroconvulsive therapy: historical perspective and current issues.

    2013-06-01

    Retrograde amnesia following electroconvulsive therapy (ECT) is a major concern for both patients and clinicians. In contemporary ECT research, retrograde autobiographical amnesia (RAA) is commonly measured with instruments assessing autobiographical memory (AM) consistency over time. However, normal AM recall loses in consistency with the passage of time, and time has a differential effect on stability of personal memories. In addition, experiencing depression is associated with a decreased ability to recall specific AMs, and this difficulty may persist in the euthymic phase of recurrent depression. Despite these scientific facts, relatively few attempts have been made to accurately measure the specific effect of ECT on AM independent of both normal and mood-associated forgetting over time. This major gap in our knowledge prevents us at present from objectively quantifying the nature and extent of RAA associated with ECT. In turn, this hinders our identifying and implementing strategies for prevention or remediation of AM deficits. The present article aims to provide an up-to-date review and historical perspective of this major methodological conundrum for ECT research, highlight current issues in retrograde amnesia assessment following ECT, and propose directions for future studies. In conclusion, we suggest methods to reliably and specifically measure the extent and progression over time of ECT-associated RAA independently from persistent depressive symptoms' contribution and normal loss in AM consistency over time.

    Data show that international medical graduates (IMGs), both US and foreign born, are more likely to enter primary care specialties and practice in underserved areas. Comprehensive assessments of representation trends for IMGs in the US physician workforce are limited. We reported current and historical representation trends for IMGs in the graduate medical education (GME) training pool and US practicing physician workforce. We compared representation for the total GME and active practicing physician pools with the 20 largest residency specialties. A 2-sided test was used for comparison, with P  < .001 considered significant. To assess significant increases in IMG GME trainee representation for the total pool and each of the specialties from 1990-2015, the slope was estimated using simple linear regression. IMGs showed significantly greater representation among active practicing physicians in 4 specialties: internal medicine (39%), neurology (31%), psychiatry (30%), and pediatrics (25%). IMGs in GME showed significantly greater representation in 5 specialties: pathology (39%), internal medicine (39%), neurology (36%), family medicine (32%), and psychiatry (31%; all P  < .001). Over the past quarter century, IMG representation in GME has increased by 0.2% per year in the total GME pool, and 1.1% per year for family medicine, 0.5% for obstetrics and gynecology and general surgery, and 0.3% for internal medicine. IMGs make up nearly a quarter of the total GME pool and practicing physician workforce, with a disproportionate share, and larger increases over our study period in certain specialties.

    Harm reduction and structural approaches to reduce HIV risk among sex workers face several barriers. One such barrier is based on moral arguments, and it has a rich historical context. This article examines the historical context of interventions with sex workers in New York City during the Progressive Era (1890-1920). Present at the time, though under a different name, the harm reduction approach was largely dismissed. These same moral underpinnings may be active today in driving interventions and policy toward those that are morally focused and away from those that focus on harm reduction and structural change.

    Approximately 25 yr ago, the first computer-based process control systems, including computer-generated displays, appeared. It is remarkable how slowly the human-computer interfaces (HCI's) of such systems have developed over the years. The display design approach in those early days had its roots in the topology of the process. Usually, the information came from the piping and instrumentation diagrams. Later, some important additional functions were added to the basic system, such as alarm and trend displays. Today, these functions are still the basic ones, and the end-user displays have not changed much except for improved display quality in terms of colors, font types and sizes, resolution, and object shapes, resulting from improved display hardware.Today, there are two schools of display design competing for supremacy in the process control segment of the HCI community. One can be characterized by extension and integration of current practice, while the other is more revolutionary.The extension of the current practice approach can be described in terms of added system functionality and integration. This means that important functions for the plant operator - such as signal validation, plant overview information, safety parameter displays, procedures, prediction of future states, and plant performance optimization - are added to the basic functions and integrated in a total unified HCI for the plant operator.The revolutionary approach, however, takes as its starting point the design process itself. The functioning of the plant is described in terms of the plant goals and subgoals, as well as the means available to reach these goals. Then, displays are designed representing this functional structure - in clear contrast to the earlier plant topology representation. Depending on the design approach used, the corresponding displays have various designations, e.g., function-oriented, task-oriented, or ecological displays.This paper gives a historical overview of past

    During the past three decades, improvements in the treatment of childhood leukemia have resulted in high cure rates, particularly for acute lymphoblastic leukemia (ALL). Unfortunately, successful therapy has come with a price, as significant morbidity can result from neurological affects which harm the brain and spinal cord. The expectation and hope is that chemotherapy, as a primary means of CNS therapy, will result in acceptable disease control with less CNS morbidity than has been observed with combinations of chemotherapy and radiotherapy over the past several decades. In this review we discuss the poignant, historical aspects of CNS leukemia therapy, outline current methods of systemic and CNS leukemia therapy, and present imaging findings we have encountered in childhood leukemia patients with a variety of acute neurological conditions. A major objective of our research is to understand the neuroimaging correlates of acute and chronic effects of cancer and therapy. Specific features related to CNS leukemia and associated short-term toxicities, both disease- and therapy-related, are emphasized in this review with the specific neuroimaging findings. Specific CNS findings are similarly important when treating acute myelogenous leukemia (AML), and details of leukemic involvement and toxicities are also presented in this entity. Despite contemporary treatment approaches which favor the use of chemotherapy (including intrathecal therapy) over radiotherapy in the treatment of CNS leukemia, children still occasionally experience morbid neurotoxicity. Standard neuroimaging is sufficient to identify a variety of neurotoxic sequelae in children, and often suggest specific etiologies. Specific neuroimaging findings frequently indicate a need to alter antileukemia therapy. It is important to appreciate that intrathecal and high doses of systemic chemotherapy are not innocuous and are associated with acute, specific, recognizable, and often serious neurological

    Full Text Available Following WHO recommandations and in order to improve medical coverage, Madagascar officially recognized in 2007 its traditional medicine as a legitimate practice.UNESCO, to sustain traditional healers in the Indian Ocean, wanted to use anthropological tools to explore the current situation in Madagascar.Despit a plurality of practices, data collected for three months in the Southeast of the Island, allowed us to identify some fundamental aspects of Malagasy traditional medicine, such as the omnipresence of symbolism or the complexity of healers’ roles at the crossroads of social, sacred and therapeutic registries.The study shows that the national policy on traditional medicine improves gradually the promotion of these practices too often undervalued. Nevertheless, the institutional context exposes weaknesses which might explain the difficulty encountered by some tradipractitioners to find their place in this new regulation. Indeed, regarding the current context, a reducing process of the healers' practices is likely to emerge.

    Full Text Available Abstract Background Many investigators are concerned that the modes of implementation and enforcement of the federal regulations designed to protect children are unduly impeding pediatric clinical research. Objective To assess regulatory impediments to clinical research involving children and to develop recommendations to ameliorate them. Participants The Pediatric Endocrine Society and The Endocrine Society convened a consensus conference involving experts and stakeholders in patient-oriented research involving children and adolescents in 2008. Consensus process Following presentations that reviewed problematic issues around key regulations, participants divided into working groups to develop potential solutions that could be adopted at local and federal levels. Presentations to the full assembly were then debated. A writing committee then drafted a summary of the discussions and main conclusions, placing them in historical context, and submitted it to all participants for comment with the aim of developing consensus. Conclusions Recommendations designed to facilitate the ethical conduct of research involving children addressed the interpretation of ambiguous regulatory terms such as "minimal risk" and "condition" and called for the development by professional societies of best practice primers for common research procedures that would be informative to both investigators and institutional review boards. A call was issued for improved guidance from the Office for Human Research Protections and Food and Drug Administration as well as for the development by professional societies of a process to monitor progress in improving human subject research regulation. Finally, a need for systematic research to define the nature and extent of institutional obstacles to pediatric research was recognized.

    Full Text Available Refunctioning is a widely used method for protecting historical structures. However, throughout architectural education, functioning historical structures and producing new designs in terms of historical pattern do not attract great attention within the framework of design studios. It is a fact that in such schools that abovementioned items are more popular, the connection between protection oriented studio and design studio is pretty weak. In this study refunctioning was discussed as a design studio topic in relation to the old girls' teacher training school and its immediate surroundings. The primary objective of this design studio is to increase architecture students' awareness in terms of visual and perceptual levels of project designs in historical patterns. Within the context of this manuscript, the experiences gained during design studio process were transferred and discussed.

    2016-01-01

    Following up on the largest case-control study of malignant mesothelioma yet performed, investigators at the London School of Hygiene and Tropical Medicine assessed 1732 male and 670 female cases as of May 2013. Epidemiological findings of a subset of these were published previously, excluding patients who died or who refused to be interviewed. Pathology reports were collected for subjects, including those both eligible and ineligible for epidemiology study based on vital status. The current investigation examined 860 cases having pathology reports available. Sixty-one cases were diagnosed using cytology only, often with equivocal diagnoses, while 799 reported at least a biopsy of the tumor. Of these, 748 had pathology sufficiently detailed for evaluation. These reports were examined for basis of diagnosis, differences between study cases and ineligible cases, pathology characteristics, and immunohistochemical and other tests used. The most prominent subtype was epithelioid (64% of study cases but only 49% of ineligible cases). Biphasic subtype was present in 10% of study cases and 16% of those ineligible. Sarcomatoid subtype was present in 7% of study cases and 19% of ineligible cases, most of whom died. Twelve percent of study cases displayed no specified subtype, versus 7% of ineligible cases. Of recorded immunohistochemical stains specific for mesothelial cell origin, calretinin (95%) and CK 5/6 or CK5 alone (84%) were by far the most common. Calretinin and CK 5/6 or CK 5 alone were also most sensitive and positive in 92% of cases presenting with surgical pathology report. Ninety percent of cases had at least one immunohistochemical marker for possible lung carcinoma applied, with BER-Ep4 and TTF-1 the most frequent at 68% and CEA at 58%. TTF-1 and CEA were positive in 1% or less of cases. Patterns of use and positive and negative results for each of these as well as other immunohistochemical stains are presented and discussed, along with a brief historical

    Full Text Available This paper presents studies of wooden installations which use the power of water flows for electric power generation and for other industrial activities. This paper focuses on the historical context as well by identifying the places where wooden installations have worked since the 15th century, in the Fagaras Mountains foothills, on the Berivoi River valley, by using the power of water flows for timber production activities, fulling mills and mills. The paper also aims through the archaeological sites which contain important material and highlight the traditions of the Romanian nation around these places and the development of these old craft techniques from ancient times. Apart the identification of these sites (which are not found on any map, other places with hydropower potential are rediscovered, and by using some low investments, they may become centres to produce electricity needed for holiday dwellings, guesthouses, agricultural and livestock facilities located far away from the power station. The implementation of 'green energy' which generates systems by using wood installations as mechanical subsystems of water flow energy conversion, in combination with modern subsystems of conversion, storage and transport, as well as the development of some integrated modules (hydroelectric, photovoltaic and eoalian represent the optimal solution that contribute to the development of foothill areas, in the context of promotion of the Romanian traditional spirituality and the development of sustainable programs. This paper proposes solutions to promote the small hydroelectric power stations on the watercourses of mountains and foothills regions by using fractions of minimum water flows thereof, of maintaining a water flow on the main valley as well, so as the aquatic fauna permanently regenerate, and to protect the specificity of the environment and of the surrounding areas. The studies were referred to Berivoi River valley from the northern part of

    South Africans have a long association with water. It has provided a source of food, a medium for trade and a catalyst for migration and development. The country's geographical position as a crossroads of maritime trade between Europe and the East means that its history is inextricably linked to the history of the rest of the world. The result is a multi-faceted representation of sites, objects and mythologies related to water and maritime heritage that reflect not only local historical and social development, but global cultural change as well. Given the importance of South Africa's underwater cultural heritage (UCH), managers have grappled with management principles, ethics and theoretical models in an effort to produce and enforce heritage legislation that is relevant and effective. This paper outlines South Africa's maritime context from 1.5 million years ago until the present, summarises legislative and mitigation developments over the past half century and provides details of current trends in maritime archaeology and UCH management at the southern tip of Africa. Training programmes and public awareness are keys to this strategy to bring UCH and maritime archaeology into the mainstream and counter treasure hunting and looting of this rich, friable resource.

    The muriqui (Brachyteles spp.), endemic to the Atlantic Forest of Brazil, is the largest primate in South America and is endangered, mainly due to habitat loss. Its distribution limits are still uncertain and need to be resolved in order to determine their true conservation status. Species distribution modeling (SDM) has been used to estimate potential species distributions, even when information is incomplete. Here, we developed an environmental suitability model for the two endangered species of muriqui (Brachyteles hypoxanthus and B. arachnoides) using Maxent software. Due to historical absence of muriquis, areas with predicted high habitat suitability yet historically never occupied, were excluded from the predicted historical distribution. Combining that information with the model, it is evident that rivers are potential dispersal barriers for the muriquis. Moreover, although the two species are environmentally separated in a large part of its distribution, there is a potential contact zone where the species apparently do not overlap. This separation might be due to either a physical (i.e., Serra da Mantiqueira mountains) or a biotic barrier (the species exclude one another). Therefore, in addition to environmental characteristics, physical and biotic barriers potentially shaped the limits of the muriqui historical range. Based on these considerations, we proposed the adjustment of their historical distributional limits. Currently only 7.6% of the predicted historical distribution of B. hypoxanthus and 12.9% of B. arachnoides remains forested and able to sustain viable muriqui populations. In addition to measurement of habitat loss we also identified areas for conservation concern where new muriqui populations might be found.

    Highlights: • A comparison among methods for calculating heating degree-days (HDD) is provided. • ASHRAE method is used for analyze the historical trends of HDD and CDD in Italy. • The HDD historical profile for Rome is decomposed in its characterizing components. - Abstract: Degree days (DD) represent a versatile climatic indicator which is commonly used in the analysis of building energy performance, as e.g. (i) to perform energetic assessment of existent and new buildings, (ii) to analyze the territory energy consumption, (iii) to develop scenario analyses in terms of energy consumption forecasting, and so on. Different methods can be used for determining the DD values, depending on the available climatic data of each location. In the present paper, the simplified methods based on reduced climatic data set have been compared assuming the mean daily degree-hours method (MDDH) as reference. Hourly temperature profiles recorded by the meteorological station located at the University of Genoa have been used for these analyses. In the second part of the present work, the ASHRAE method has been selected to calculate heating (HDD) and cooling (CDD) degree days for several Italian cities. In particular, daily meteorological data of several Italian cities (covering the whole climatic conditions which occur in Italy) have been used to calculate heating and cooling degree days in the period 1978–2013, in order to analyze their trends in the last years. Finally, the historical profiles of Rome and Milan have been treated as time-series and analyzed in the frequency domain, performing a decomposition of the original data set into different characterizing components. This simplified approach permits to deeply analyze the historical profile of DD and represents a simple starting point method for future analyses with forecasting perspectives

    Management of menstruation in contexts of humanitarian emergencies can be challenging. A lack of empirical research about effective interventions which improve menstrual hygiene management (MHM) among female populations in humanitarian emergencies and a lack of clarity about which sectors within a humanitarian response should deliver MHM interventions can both be attributable to the lack of clear guidance on design and delivery of culturally appropriate MHM intervention in settings of humanitarian emergencies. The objective of this review was to collate, summarize, and appraise existing peer-reviewed and gray literature that describes the current scenario of MHM in emergency contexts in order to describe the breadth and depth of current policies, guidelines, empirical research, and humanitarian aid activities addressing populations' menstrual needs. A structured-search strategy was conducted for peer-reviewed and gray literature to identify studies, published reports, guidelines, and policy papers related to menstrual response in emergency humanitarian contexts. Of the 51 articles included in the review, 16 were peer-reviewed papers and 35 were gray literature. Most of the literature agreed that hardware interventions should focus on the supply of adequate material (not only absorbent material but also other supportive material) and adequate sanitation facilities, with access to water and private space for washing, changing, drying, and disposing menstrual materials. Software interventions should focus on education in the usage of materials to manage menstruation hygienically and education about the female body's biological processes. There was clear agreement that the needs of the target population should be assessed before designing any intervention. Although there is insight about which factors should be included in an effective menstrual hygiene intervention, there is insufficient empirical evidence to establish which interventions are most effective in

    We examined the effects of a commonly used preservation technique on mercury concentration in fish tissue. After fixing fish muscle tissue in formalin followed by preservation in isopropanol, we found that mercury concentration in fish muscle tissue increased by 18%, reaching an asymptote after 40 days. We used formalin-isopropanol-preserved longear sunfish (Lepomis megalotis) from the Sam Noble Oklahoma Museum of Natural History to examine historical changes and predict current mercury concentrations in fish from two rivers in southeastern Oklahoma. Glover River was free-flowing, while Mountain Fork River was impounded in 1970 and a coldwater trout fishery was established upstream from the collection site in 1989. Mercury concentrations in longear sunfish from Glover River showed no historical changes from 1963 to 2001. Mercury concentrations in longear sunfish from Mountain Fork River showed no change from 1925 to 1993 but declined significantly from 1993 to 2003. We also compared mercury concentrations of the most recently collected longear sunfish in the museum to mercury concentrations of unpreserved fish collected from the rivers in 2006. Concentrations of mercury in museum fish were not significantly different from mercury concentrations in unpreserved fish we collected from the rivers. Our study indicates that preserved museum fish specimens can be used to evaluate historical changes and predict current levels of mercury contamination in fish.

  3. Potential effects of climate change on a marine invasion: The importance of current context

    Full Text Available Species invasions threaten marine biodiversity globally. There is a concern that climate change is exacerbating this problem. Here, we examined some of the potential effects of warming water temperatures on the invasion of Western Atlantic habitats by a marine predator, the Indo-Pacific lionfish (Pterois volitans and P. miles. We focussed on two temperature-dependent aspects of lionfish life-history and behaviour: pelagic larval duration, because of its link to dispersal potential, and prey consumption rate, because it is an important determinant of the impacts of lionfish on native prey. Using models derived from fundamental metabolic theory, we predict that the length of time spent by lionfish in the plankton in early life should decrease with warming temperatures, with a concomitant reduction in potential dispersal distance. Although the uncertainty around change in dispersal distances is large, predicted reductions are, on average, more than an order of magnitude smaller than the current rate of range expansion of lionfish in the Caribbean. Nevertheless, because shorter pelagic larval duration has the potential to increase local retention of larvae, local lionfish management will become increasingly important under projected climate change. Increasing temperature is also expected to worsen the current imbalance between rates of prey consumption by lionfish and biomass production by their prey, leading to a heightened decline in native reef fish biomass. However, the magnitude of climate-induced decline is predicted to be minor compared to the effect of current rates of lionfish population increases (and hence overall prey consumption rates on invaded reefs. Placing the predicted effects of climate change in the current context thus reveals that, at least for the lionfish invasion, the threat is clear and present, rather than future [Current Zoology 58 (1: 1–8, 2012].

    Full Text Available In this paper I have approached issues concerning the importance of Lean Management method in the current context of evolution of an organization. With roots in the just in time method, Lean Management model focuses on the process of changes evolving and adapting to them and regards issues such as: the dimensioning of life cycle, the dimensioning of processes, the dimensioning of ranges of products. I have also presented the relationship between Lean Management method and the human factor as a determinant in forming an organizational culture which leads to the formation and development of Lean thinking. Relevant factors which determine the change and interact with the Lean Management method are: training, motivation, teamwork spirit, communication methods, training and motivation. An important aspect of this paper is to integrate Lean Management with Six Sigma, and with other managerial techniques leading to getting quality products at low costs

    This study updates three similar investigations conducted in 1981, 1991, and 2001 on APA Division of Psychotherapy members in order to paint a contemporary portrait of psychologists conducting psychotherapy and to chronicle historical trends among Division 29 members. Four hundred twenty-eight psychologists (43% response) completed a questionnaire in 2012 regarding their demographic characteristics, professional activities, theoretical orientations, employment settings, and career experiences. The results point to an increasingly female and aging membership, which continues to be employed primarily in private practices and universities. Psychodynamic (27%), integrative (25%), and cognitive (17%) orientations continue to prevail. Professional activities have remained quite similar across the past 30 years with the exception of declines in projective testing and growth in neuropsychological and health testing. Training and career satisfactions remain high as well.

    Urban landscapes are increasingly recognized as providing important ecosystem services (ES) to their occupants. Yet, urban ES assessments often ignore the complex spatial heterogeneity and land-use history of cities. Soil-based services may be particularly susceptible to land-use legacy effects. We studied indicators of three soil-based ES, carbon storage, water quality regulation, and runoff regulation, in a historically agricultural urban landscape and asked (1) How do ES indicators vary with contemporary land cover and time since development? (2) Do ES indicators vary primarily among land-cover classes, within land-cover classes, or within sites? (3) What is the relative contribution of urban land-cover classes to potential citywide ES provision? We measured biophysical indicators (soil carbon [C], available phosphorus [P], and saturated hydraulic conductivity [K s ]) in 100 sites across five land-cover classes, spanning an ~125-year gradient of time since development within each land-cover class. Potential for ES provision was substantial in urban green spaces, including developed land. Runoff regulation services (high K s ) were highest in forests; water quality regulation (low P) was highest in open spaces and grasslands; and open spaces and developed land (e.g., residential yards) had the highest C storage. In developed land covers, both C and P increased with time since development, indicating effects of historical land-use on contemporary ES and trade-offs between two important ES. Among-site differences accounted for a high proportion of variance in soil properties in forests, grasslands, and open space, while residential areas had high within-site variability, underscoring the leverage city residents have to improve urban ES provision. Developed land covers contributed most ES supply at the citywide scale, even after accounting for potential impacts of impervious surfaces. Considering the full mosaic of urban green space and its history is needed to

    Full Text Available The European Union appears, in the context of a conceptual and transformational change, in the shape of a fluid structure that is continuously shaped by a wide variety of factors. Under the current redefining process, the present article pursues the amplitude of the social force in the Union’s configuration. The EU can be currently viewed as a reality found at crossroads, due to a growing fragility of public support for integration and the increasing contestation of the EU through the amplification of Eurosceptic attitudes and the rising popularity of the populist-nationalist parties. In the conditions of a populism-terrorism-migration triad that is threatening the European integration project, this article represents an attempt to provide a preliminary insight on the forces that shape the configuration of this supranational structure, with regard to the factors that are accountable for the growing scepticism among the European citizens and have shifted the citizens’ approach on the EU from a permissive consensus to a constraining dissensus.

    In December 2014, China announced that only voluntarily donated organs from citizens would be used for transplantation after January 1, 2015. Many medical professionals worldwide believe that China has stopped using organs from death-row prisoners. In the present article, we briefly review the historical development of organ procurement from death-row prisoners in China and comprehensively analyze the social-political background and the legal basis of the announcement. The announcement was not accompanied by any change in organ sourcing legislations or regulations. As a fact, the use of prisoner organs remains legal in China. Even after January 2015, key Chinese transplant officials have repeatedly stated that death-row prisoners have the same right as regular citizens to "voluntarily donate" organs. This perpetuates an unethical organ procurement system in ongoing violation of international standards. Organ sourcing from death-row prisoners has not stopped in China. The 2014 announcement refers to the intention to stop the use of organs illegally harvested without the consent of the prisoners. Prisoner organs procured with "consent" are now simply labelled as "voluntarily donations from citizens". The semantic switch may whitewash sourcing from both death-row prisoners and prisoners of conscience. China can gain credibility only by enacting new legislation prohibiting use of prisoner organs and by making its organ sourcing system open to international inspections. Until international ethical standards are transparently met, sanctions should remain.

    Spanish moss (Tillandsia usnesoides) is an epiphytic member of the pineapple family, Historically, tissue levels in this plant have illustrated the elevated concentration of lead near well traveled roads, as well as nickel and tin in the vicinity of battery fabrication or smelting facilities, respectively. From a survey of Spanish moss plants growing throughout the Southeast, mercury at or slightly above the limit of detection was present in eight of 128 samples. Five of these samples were collected in Florida. As part of a biomonitoring project, Spanish moss was collected from 1991 to 1993 around a waste-to-energy facility in Lake County, Florida, After three years, the percentage of Spanish moss samples which contained detectable levels of arsenic and cadmium decreased over time. Lead was detected in all samples collected throughout the monitoring period, but the mean concentration decreased from 3.7 mg/kg on a dry weight basis (1991) to 1.4 mg/kg (1993). This trend in lead levels may indicate clearance that is occurring due to the discontinuation of leaded gasoline. The percentage of moss samples containing mercury above the limit of detection increased from 67% (1991) to 97% (1993); however, mean concentrations do not support a trend in increasing concentration of this element (0.30 mg/kg on a fresh weight basis in 1991 vs. 0.19 mg/kg in 1993). Apparently, atmospheric metal concentrations are not increasing in the vicinity of the facility at this time.

    The author analyzed the problem in historical, diagnostic and psychopathological aspects and presented the results of his own study. The aim was to study the structure and dynamics of endogenous juvenile mixed states in order to work out the psychopathological typology and to clarify the criteria of diagnosis, differential treatment and clinical-social prognosis. The study included 174 patients, 118 men and 56 women, aged from 17 to 25 years (mean age 20, 4 years). Depressive states were found in 65%, mania in 16% and mixed in 19% of patients. The clinical differentiation of mixed states was carried out basing on the dominating pole of affective disorders and the following types were singled out and described: mania type (dysphoria-like mania)--34%, depressive type (association-driven depression)--38%; alternating type of mixed states--28%. The preference of the formation of alternating and atypical variants of mixed states in the juvenile age demonstrated in the study may reflect the pathogenetic and pathoplastic effect of biological features characteristic of this age--lability and polymorphism of clinical presentations as well as immaturity of emotional and cognitive spheres.

    Full Text Available In this article the author offers a historical and bibliological analysis of a Cyrillic edition of the German Protestant Bishop Wilhelm Stratemann work «Featron or Historical Shame» (SPb.: typography of Alexander Nevsky Monastery, 1724 against the background of the Russian book culture, historical thought and book publishing in the first quarter of XVIII century.The research has revealed that the publication of secular books in Russia during this period was under the governmental control and largely depended on the reformation activity of Peter I. We have defined that the main goal of secular publishing was the distribution of enlightenment, science and education ideas. In the article we have revealed the characteristic features of the development of Western European Protestant and Catholic historiography of XVI-XVII centuries. The study of sources and scientific materials allows us to disclose the value of the work of W. Stratemann as the first Russian edition of the world history textbook in the distribution and popularization of historical knowledge, as well as its influence on the Russian historical science formation. We have studied the main historical ideas of W. Stratemann work and G. Buzhinsky foreword, as well as their influence on the development of historical thought in Russia during the studied period. The author attempts to make a bibliological analysis of W. Stratemann publication exemplars which are stored in the holdings of rare books of the largest libraries of Kyiv: the printing features of these printed works, bindings and engravings state, contents of provenances, marginalia etc are characterized.

    The Queen Charlotte fault (QCF) is a dextral transform system located offshore of southeastern Alaska and western Canada, accommodating ∼4.4  cm/yr of relative motion between the Pacific and North American plates. Oblique convergence along the fault increases southward, and how this convergence is accommodated is still debated. Using seismic reflection data, we interpret offshore basement structure, faulting, and stratigraphy to provide a geological context for two recent earthquakes, an Mw 7.5 strike‐slip event near Craig, Alaska, and an Mw 7.8 thrust event near Haida Gwaii, Canada. We map downwarped Pacific oceanic crust near 54° N, between the two rupture zones. Observed downwarping decreases north and south of 54° N, parallel to the strike of the QCF. Bending of the Pacific plate here may have initiated with increased convergence rates due to a plate motion change at ∼6  Ma. Tectonic reconstruction implies convergence‐driven Pacific plate flexure, beginning at 6 Ma south of a 10° bend the QCF (which is currently at 53.2° N) and lasting until the plate translated past the bend by ∼2  Ma. Normal‐faulted approximately late Miocene sediment above the deep flexural depression at 54° N, topped by relatively undeformed Pleistocene and younger sediment, supports this model. Aftershocks of the Haida Gwaii event indicate a normal‐faulting stress regime, suggesting present‐day plate flexure and underthrusting, which is also consistent with reconstruction of past conditions. We thus favor a Pacific plate underthrusting model to initiate flexure and accommodation space for sediment loading. In addition, mapped structures indicate two possible fault segment boundaries along the QCF at 53.2° N and at 56° N.

    Spatial variation of elemental deposition to lichen receptors across Maricopa County, Arizona, USA is documented for 1998 and historical trends relative to 1974 are documented. - Spatial patterns of atmospheric deposition of trace elements to an epilithic lichen were assessed using a spatial grid of 28 field sites in 1998 throughout Maricopa County, Arizona, USA. In addition, samples of Xanthoparmelia spp. from Arizona State University lichen herbarium material (1975-1976) was utilized for a limited number of sites in order to explore temporal trends. The lichen material was cleaned, wet digested and analyzed by ICP-MS for a suite of elemental concentrations [antimony (Sb), cadmium (Cd), cerium (Ce), chromium (Cr), cobalt (Co), copper (Cu), dysprosium (Dy), europium (Eu), gadolinium (Gd), gold (Au), holmium (Ho), lead (Pb), lutetium (Lu), neodymium (Nd), nickel (Ni), palladium (Pd), platinum (Pt), praseodymium (Pr), samarium (Sm), scandium (Sc), silver (Ag), terbium (Tb), thulium (Tm), tin (Sn), uranium (U), ytterbium (Yb), yttrium (Y), and zinc (Zn)]. Cluster analysis and principal component analysis suggest three major factors, which, depending on regional aerosol fractionation, explain most of the variation in elemental signatures: (1) a group of widely distributed rare earth elements (2) a highly homogenous Co, Cr, Ni, and Sc component representing the influence of mafic rocks, and (3) anthropogenic emissions. Elemental concentrations in Maricopa County lichens were generally comparable to those reported for relatively unpolluted areas. Only highly urbanized regions, such as the greater Phoenix Metropolitan Area and the NW corner of the county, exhibited elevated concentrations for Zn, Cu, Pb, and Cd. Lead levels in lichens have fallen over the last 30 years by 71%, while Zn concentrations for some regions have increased by as much as 245%. From the spatial pattern of elemental deposition for Cd, Cu, Ni, Pr, Pb, and Cu, we infer that agriculture, mining

    The development of new fibrilar materials based on electrospinning (ES) technique has a notable history of nearly four centuries of discoveries and results. The eletrospinning manufacturing is one of the most widely reported methods for nanofiber (NF) manufacturing, providing security, high quality and productivity. In spite of the first patent about electrospinning has been applied in April 5(th), 1900 by John Francis Cooley, a historical perspective (since 1600s) about this amazing discovery represents an important step for future applications. Nanofibers have been considered one of the top interesting fundamental study objects for academicians, and greatest intriguing business materials for modern industry. As a consequence, lucrative organizations and companies have explored the relevance of nanofibers. In this paper, the quantity of published manuscripts and patent inventions is presented and the correlation of research activities to the production of new electrospinning materials is shown. China and the United States have been leading in electrospinning and nanofibers development. The company triumph is mostly dependent on applications improvement relevant for broader business society. A dramatic rise of interest in nanofibers produced by electrospinning technique has been confirmed due to the publication data, author's affiliation, keywords, and essential characterization procedures. Is has been shown that the number of publications on electrospinning and nanofibers researches from academic institutions is higher than industrial laboratories. More than 1,891 patents using the term "electrospinning" and 2,960 with the term "nanofibers" according to the European Patent Office at title or abstract have been filed around the world up to 2013. These numbers just continue to increase along with worldwide ES-related sales. Curiously, for the same period 11,973 electrospinning documents and 18,679 nanofibers-related (mainly manuscripts) were published considering

    In the early 20th century, the British anthropologist Melville William Hilton-Simpson (1881-1938) did explorations in Africa, mainly the Congo region and the Aurès region in Algeria. He showed considerable interest in local medicinal practices and plants used by the natives, mainly the Algerian Berbers. He left notes, letters and publications about traditional medicine which were screened for relevant information about medicinal plant use. His reports were compared with current knowledge and recent study results. Many plants described by Hilton-Simpson as therapeutically relevant could prove their efficacy in current studies which again shows that historical sources may exert some reliability. The study, however, unveiled a couple of plants reported as traditionally used, but neglected by modern science so far. These, including Marrubium supinum, Cynoglossum pictum (= C. creticum), Sonchus maritimus, and two Erodium species, are strongly recommended to be further studied. Foresightedly, this approach was already intended by Hilton-Simpson himself.

    One of the ways to analyse textbook is to trace back how such a mathematical content was explicated in a current and historical textbooks. The purpose of this study is to compare the explanation of proportion in three different textbooks from two different periods. By using praxeology, I analyse...... a current open online US textbook and two historical US textbooks. I describe how proportion is explained and appeared in examples and in exercises. The results show that each textbook has its own typical type of task and technique. I also observe that the way proportion is explained in current textbooks...... draws on what we could call ‘daily life situations’ while the historical textbooks use a more formal definition. Furthermore, I find that the historical textbooks provide more algebraic approaches to discuss property of proportion while the current textbook gives advantage for students to have more than...

    2011-04-05

    Many live, attenuated viral vaccines are derived from wild type viruses with known neurovirulent properties. To assure the absence of residual neurotoxicity, pre-clinical neurovirulence safety testing of candidate vaccines is performed. For mumps virus, a highly neurotropic virus, neurovirulence safety testing is performed in monkeys. However, laboratory studies suggest an inability of this test to correctly discern among virus strains of varying neurovirulence potential in man, and, further, some vaccines found to be neuroattenuated in monkeys were later found to be neurovirulent in humans when administered in large numbers. Over the past decade, concerted efforts have been made to replace monkey-based neurovirulence safety testing with more informative, alternative methods. This review summarizes the current status of mumps vaccine neurovirulence safety testing and insights into models currently approved and those under development. Published by Elsevier Ltd.

    Full Text Available Through the hereby study we set ourselves on an analysis over the internal control and the ways of implementation of it. The final purpose of our research is represented by the characteristics of the internal control system in the context of current accountancy regulations. The accomplishment of such goal has forced us to research the current literature in the area and also the legal regulations over internal control. Of course, the accomplishment of such a research was possible only after a pertinent analysis over the opinions expressed in specialty literature regarding this area. Our research wants to be with a theoretical and applicative character. It is based on analysing the internal control system, the methodology of internal control and the steps of internal control. We express our belief that the implementation of the internal control in a very exact manner comes as an aid to the company management and lead to the accomplishment of managerial objectives and policies. In what it regards the result of our research there can be drawn the following conclusions: from the legal regulations (OMFP nr. 3055/2009, there is no clear conclusion over the procedures and policies of implementation of internal control applicable to an economical entity; also there are not presented in a detailed way the types (forms of internal control, being presented in the legal regulations only a classification of them after the time in which they are exercised (before, during or after the finishing of the operations; also in the legal regulations there is developed a certain way of internal control, represented by the financial and accounting internal control, as if the other forms of internal control do not exist; in what regards the components of internal control, these are presented in another way, but similar to already known models of internal control (Coso and Coco; also in the legal regulations there are presented the general objectives of internal control

    Full Text Available Following formal opposition by France, the harmonized safety standards regarding manually-loaded wood chippers (EN 13525:2005+A2:2009 which presumed compliance with the Essential Health and Safety Requirements (EHSR required by the Machine Directive (Directive 2006/42/EC, have recently been withdrawn, and a new draft of the standard is currently under revision. In order to assess the potential impact of the expected future harmonized standards within the Italian context, this study has examined the main issues in implementing EHSRs on wood chippers already being used. Safety issues regarding wood chippers already in use were identified in an analysis of the draft standard, through the observation of a number of case studies, and qualitative analysis of the essential technical interventions. A number of agricultural and forestry operators and companies participated in the study, pointing out the technical and economic obstacle facing the safety features requested by the pending new standard. It emerged that the main safety issues concerned the implementation of the reverse function, the stop bar, and the protective devices, the infeed chute dimension, the emergency stop function, and the designated feeding area. The possibility of adopting such solutions mainly depends on technical feasibility and costs, but an important role is also played by the attitude towards safety and a lack of adequate information regarding safety obligations and procedures among users.

    In Argentina there are two tephritid fruit fly species of major economic and quarantine importance: the exotic Ceratitis capitata that originated from Southeast Africa and the native Anastrepha fraterculus. In recent years, the use of fruit fly parasitoids as biocontrol agents has received renewed attention. This increasing interest has recently led to the establishment of a program for the mass rearing of five million Diachasmimorpha longicaudata parasitoids per week in the BioPlanta San Juan facility, San Juan, Argentina. The first augmentative releases of D. longicaudata in Argentina are currently occurring on commercial fig crops in rural areas of San Juan as part of an integrated fruit fly management program on an area-wide basis. In this context, research is ongoing to assess the suitability of indigenous parasitoid species for successful mass rearing on larvae of either C. capitata or A. fraterculus. The purpose of this article is to provide a historical overview of the biological control of the fruit fly in Argentina, report on the strategies currently used in Argentina, present information on native parasitoids as potential biocontrol agents, and discuss the establishment of a long-term fruit fly biological control program, including augmentative and conservation modalities, in Argentina's various fruit growing regions.

    Directory of Open Access Journals (Sweden)

    George P. Dinos

    2016-06-01

    Full Text Available Chloramphenicol (CAM is the D-threo isomer of a small molecule, consisting of a p-nitrobenzene ring connected to a dichloroacetyl tail through a 2-amino-1,3-propanediol moiety. CAM displays a broad-spectrum bacteriostatic activity by specifically inhibiting the bacterial protein synthesis. In certain but important cases, it also exhibits bactericidal activity, namely against the three most common causes of meningitis, Haemophilus influenzae, Streptococcus pneumoniae and Neisseria meningitidis. Resistance to CAM has been frequently reported and ascribed to a variety of mechanisms. However, the most important concerns that limit its clinical utility relate to side effects such as neurotoxicity and hematologic disorders. In this review, we present previous and current efforts to synthesize CAM derivatives with improved pharmacological properties. In addition, we highlight potentially broader roles of these derivatives in investigating the plasticity of the ribosomal catalytic center, the main target of CAM.

    To describe the history, refinements, implementation, physiology, and clinical outcomes achieved over the past several centuries of thyroid hormone replacement strategies. A Medline search was initiated using the following search terms: bioidentical thyroid hormone, thyroid hormone extract, combination thyroxine (T4) and tri-iodothyronine (T3) therapy, homeopathic thyroid hormone therapy, and thyroid hormone replacement. Pertinent articles of interest were identified by title (and where available abstract) for further review. Additional references were identified during a review of the identified literature. A rich history of physician intervention in thyroid dysfunction was identified dating back more than 2 millennia. Although not precisely documented, thyroid ingestion from animal sources had been used for centuries but was finally scientifically described and documented in Europe over 130 years ago. Since the reports by Bettencourt and Murray, there has been a continuous documentation of outcomes, refinement of hormone preparation production, and updating of recommendations for the most effective and safe use of these hormones for relieving the symptoms of hypothyroidism. As the thyroid extract preparations contain both levothyroxine (LT4) and liothyronine (LT3), current guidelines do not endorse their use as controlled studies do not clearly document enhanced objective outcomes compared with LT4 monotherapy. Among current issues cited, the optimum ratio of LT4 to LT3 has yet to be determined, and the U.S. Food and Drug Administration (FDA) does not appear to be monitoring the thyroid hormone ratios or content in extract preparations on the market. Taken together, these limitations are important detriments to the use of thyroid extract products. The evolution of thyroid hormone therapies has been significant over the extended period of time they have been in use to treat hypothyroidism. Although numerous websites continue to advocate the use of thyroid hormone

    Different types of managed aquifer recharge (MAR) schemes are widely distributed and applied on various scales and for various purposes in the European countries, but a systematic categorization and compilation of data has been missing up to now. The European MAR catalogue presented herein contains various key parameters collected from the available literature. The catalogue includes 224 currently active MAR sites found in 23 European countries. Large quantities of drinking water are produced by MAR sites in Hungary, Slovakia, the Netherlands, Germany, Finland, Poland, Switzerland and France. This inventory highlights that, for over a century, MAR has played an important role in the development of European water supply and contributes to drinking-water production substantially. This development has occurred autonomously, with "trial-and-error" within the full range of climatically and hydrogeologically diverse conditions of the European countries. For the future, MAR has the potential to facilitate optimal (re)use and storage of available water resources and to take advantage of the natural purification and low energy requirements during MAR operations. Particularly with respect to the re-use of wastewater treatment-plant effluent and stormwater, which is currently underdeveloped, the use of MAR can support the public acceptance of such water-resource efficient schemes. Particularly for the highly productive and urbanized coastal zones, where the pressure on freshwater supplies increases by growing water demand, salinization and increased agricultural needs for food production (such as along the Mediterranean and North Sea coasts), MAR is expected to be increasingly relied on in Europe.

    Cannabis (marijuana) has been used for medicinal purposes for millennia, said to be first noted by the Chinese in c. 2737 BCE. Medicinal cannabis arrived in the United States much later, burdened with a remarkably checkered, yet colorful, history. Despite early robust use, after the advent of opioids and aspirin, medicinal cannabis use faded. Cannabis was criminalized in the United States in 1937, against the advice of the American Medical Association submitted on record to Congress. The past few decades have seen renewed interest in medicinal cannabis, with the National Institutes of Health, the Institute of Medicine, and the American College of Physicians, all issuing statements of support for further research and development. The recently discovered endocannabinoid system has greatly increased our understanding of the actions of exogenous cannabis. Endocannabinoids appear to control pain, muscle tone, mood state, appetite, and inflammation, among other effects. Cannabis contains more than 100 different cannabinoids and has the capacity for analgesia through neuromodulation in ascending and descending pain pathways, neuroprotection, and anti-inflammatory mechanisms. This article reviews the current and emerging research on the physiological mechanisms of cannabinoids and their applications in managing chronic pain, muscle spasticity, cachexia, and other debilitating problems.

  15. Chaos as a psychological construct: historical roots, principal findings, and current growth directions.

    Science.gov (United States)

    Guastello, Stephen J

    2009-07-01

    The landmarks in the use of chaos and related constructs in psychology were entwined with the growing use of other nonlinear dynamical constructs, especially catastrophes and self-organization. The growth in substantive applications of chaos in psychology is partially related to the development of methodologies that work within the constraints of psychological data. The psychological literature includes rigorous theory with testable propositions, lighter-weight metaphorical uses of the construct, and colloquial uses of "chaos" with no particular theoretical intent. The current state of the chaos construct and supporting empirical research in psychological theory is summarized in neuroscience, psychophysics, psychomotor skill and other learning phenomena, clinical and abnormal psychology, and group dynamics and organizational behavior. Trends indicate that human systems do not remain chaotic indefinitely; they eventually self-organize, and the concept of the complex adaptive system has become prominent. Chaotic turbulence is generally higher in healthy systems compared to unhealthy systems, although opposite appears true in mood disorders. Group dynamics research shows trends consistent with the complex adaptive system, whereas organizational behavior lags behind in empirical studies relative to the quantity of its theory. Future directions for research involving the chaos construct and other nonlinear dynamics are outlined.

    The complex and sometimes controversial subject of malrotation and midgut volvulus is reviewed commencing with the 19th-century Bohemian anatomist, Vaclav Treitz, who described the suspensory muscle anchoring of the duodenal-jejunal junction in the left upper quadrant, and continuing with William Ladd, the 20th-century American ''father of pediatric surgery'' who pioneered the surgical treatment of midgut volvulus. In this review, we present the interesting history of malrotation and discuss the current radiologic and surgical controversies surrounding its diagnosis and treatment. In the symptomatic patient with malrotation and possible midgut volvulus, prompt diagnosis is critical. The clinical examination and plain film are often confusing, and delayed diagnosis can lead to significant morbidity and death. Despite recent intense interest in the position of the mesenteric vessels on US and CT scans, the upper gastrointestinal series remains the fastest and most accurate method of demonstrating duodenal obstruction, the position of the ligament of Treitz, and, if the contrast agent is followed distally, cecal malposition. Controversy exists over the management of asymptomatic patients with malrotation in whom the diagnosis is made incidentally during evaluation for nonspecific complaints, prior to reflux surgery, and in those with heterotaxy syndromes.

    The relationship between pastoralists, their livestock, wildlife and the rangelands of East Africa is multi-directional, complex and long-standing. The tumultuous events of the past century, however, have rewritten the nature of this relationship, reshaping the landscapes that were created, and relied upon, by both pastoralists and wildlife. Presently, much of the interaction between wildlife and pastoralists takes place in and around protected areas, the most contentious occurring in pastoral lands surrounding national parks. In conservation terminology these areas are called buffer zones. In the past century buffer zones have been shaped by, and contributed to, restrictive conservation policies, expropriation of land, efforts to include communities in conservation, both positive and negative wildlife/livestock interactions, and political tensions. In this review paper, the authors outline the history that shaped the current relationship between pastoralists, livestock and wildlife in buffer zones in East Africa and highlight some of the broader issues that pastoralists (and pastoralism as an effective livelihood strategy) now face. Finally, they consider some of the sustainable and equitable practices that could be implemented to improve livelihoods and benefit wildlife and pastoralism alike.

  19. Computer-aided diagnosis in medical imaging: historical review, current status and future potential.

    Computer-aided diagnosis (CAD) has become one of the major research subjects in medical imaging and diagnostic radiology. In this article, the motivation and philosophy for early development of CAD schemes are presented together with the current status and future potential of CAD in a PACS environment. With CAD, radiologists use the computer output as a "second opinion" and make the final decisions. CAD is a concept established by taking into account equally the roles of physicians and computers, whereas automated computer diagnosis is a concept based on computer algorithms only. With CAD, the performance by computers does not have to be comparable to or better than that by physicians, but needs to be complementary to that by physicians. In fact, a large number of CAD systems have been employed for assisting physicians in the early detection of breast cancers on mammograms. A CAD scheme that makes use of lateral chest images has the potential to improve the overall performance in the detection of lung nodules when combined with another CAD scheme for PA chest images. Because vertebral fractures can be detected reliably by computer on lateral chest radiographs, radiologists' accuracy in the detection of vertebral fractures would be improved by the use of CAD, and thus early diagnosis of osteoporosis would become possible. In MRA, a CAD system has been developed for assisting radiologists in the detection of intracranial aneurysms. On successive bone scan images, a CAD scheme for detection of interval changes has been developed by use of temporal subtraction images. In the future, many CAD schemes could be assembled as packages and implemented as a part of PACS. For example, the package for chest CAD may include the computerized detection of lung nodules, interstitial opacities, cardiomegaly, vertebral fractures, and interval changes in chest radiographs as well as the computerized classification of benign and malignant nodules and the differential diagnosis of

  20. Current and historical perspectives on methodological flaws in processing umbilical cord blood.

    Umbilical cord blood (UCB) hematopoietic stem cells (HSC-CD34+) are valuable for treating malignant or nonmalignant disease. Processing UCB by HESPAN-6% and anti-CD34-Miltenyi particles provides insufficient cells for treating adults. Physicochemical-electrokinetic studies on UCB-mononuclear cells (MNCs) under conditions of delayed processing, ice or very low temperatures, and some cell separation media identified artifacts introduced by procedures. Adsorption of biomaterials from cell damage by temperature, degradation products after using enzymes, harsh reagents, dithiothreitol, and HESPAN affect cell properties and distribution. Miltenyi particles internalized by cells could release iron that accumulating in liver or spleen would then risk toxicity. Summary topics included the effects of temperature, HESPAN (fast sedimenting agent), glycoproteases, DNase, and dithiothreitol risk affecting cell receptors in recognition, "homing," leading to possible unintended iatrogenic bioeffects should such cells be transfused into humans. The loss of undetectable and uncaptured low CD34 antigen-bearing cells by Miltenyi particles seems to occur when the current methods of isolation of CD34+ cells and other cells are critically assessed. The purpose here is to highlight and suggest avoiding the procedural flaws involved. Preventing ice temperatures avoids ice-damaged platelets releasing biomaterials that are adsorbed on cells altering UBC-MNCs/HSC properties and cell loss. Omitting the positive selection with antibody-linked Miltenyi particles obviates the use of harsh reagents to release the cells. Internalized Miltenyi particles are a toxicity hazard that needs investigations. Achieving approximately 5% yields of CD34+ cells (153 × 10(5) /110 mL cord-placenta blood) is a major advance holding great promise, for the first time increasing the prospect of stem cell therapy of 70-kg adults, using a single UCB donation (with dose of 1.5 × 10(5) cells/kg) and

  1. Current economic cost, the ARENH (Regulated Access to the Historic (EDF) Nuclear Energy Supplier) price, the differential rent and the scarcity rent of nuclear power: some observations

    Percebois, J.

    2012-01-01

    This article sets out to explain the ARENH mechanism, the regulated price at which the EDF (France's historic monopoly supplier) must sell part of its production to its competitors in the framework of the Nome Act (New Organisation of the Electricity Market). This price by its nature is different from the Current Economic Cost (CEC) of nuclear power, as estimated by France's Government Accounting Office in its report submitted in January 2012. These two approaches revert to the problem of the determination of the scarcity rent of nuclear power in the context of the liberalised European market, in which nuclear power benefits from a 'cost' advantage relative to thermal electricity generated from fossil fuels. Furthermore, scarcity rent is not the same thing as differential rent. Selling a nuclear kWh at the price of a 'gas' kWh at certain times results in a differential rent enabling nuclear generated power to cover fixed costs. One can only speak of scarcity rent for nuclear power when the price at which the kWh is sold allows the recovery of more than is necessary to cover overall costs of nuclear power and it is this scarcity rent and its allocation that is the subject of debate.

    Full Text Available The purpose of this study was to investigate the importance of present and historical climate as determinants of current species richness pattern of forestry trees in South America. The study predicted the distribution of 217 tree species using Maxent models, and calculated the potential species richness pattern, which was further deconstructed based on range sizes and modeled against current and historical climates predictors using Geographically Weighted Regressions (GWR analyses. The current climate explains more of the wide-ranging species richness patterns than that of the narrow-ranging species, while the historical climate explained an equally small amount of variance for both narrow-and-wide ranging tree species richness patterns. The richness deconstruction based on range size revealed that the influences of current and historical climate hypotheses underlying patterns in South American tree species richness differ from those found in the Northern Hemisphere. Notably, the historical climate appears to be an important determinant of richness only in regions with marked climate changes and proved Pleistocenic refuges, while the current climate predicts the species richness across those Neotropical regions, with non-evident refuges in the Last Glacial Maximum. Thus, this study's analyses show that these climate hypotheses are complementary to explain the South American tree species richness. Keywords: climate changes, glacial refuges, water-energy availability, GWR analysis, spatial non-stationarity

  4. The current regulatory requirements on optimisation and BAT in Sweden in the context of geological disposal

    2010-01-01

    Bjorn Dverstorp, Swedish Radiation Safety authority (SSM) presented 'The current regulatory requirements on optimisation and BAT in Sweden in the context of geological disposal'. In Sweden, a nuclear waste repository will be evaluated according to both to general environmental legislation (the Environmental Code, SFS, 1998:808) and according to more specific requirements in the Act on Nuclear Activities (SFS, 1984:3) and the Radiation Protection Act (SFS, 1988:220). The evaluations according to these laws will be carried out according to two separate, but coordinated, legal-review and decision-making processes. This will be a basis for the siting process. Although the requirements on BAT and siting in the Environmental Code apply to radiological protection, they aim at a broader system optimisation. The more specific requirements on optimisation and BAT of radiological protection of geological disposal systems are given in the regulations associated with the Radiation Protection Act. The Swedish radiation protection regulations (SSM, 2009) comprise three corner stones: a risk target, environmental protection goals and the use of optimisation and BAT. In SSM' s guidance optimisation is defined as a means to reduce risk, guided by the results of risk calculations. In case of a conflict between BAT and optimisation, measures satisfying BAT should have priority. Application of optimisation and BAT on different timescales are described as well as for human intrusion scenarios. B. Dverstorp explained that because of uncertainties in the long term there is a need for additional arguments in the safety case in support of decision making. It is in this context that the requirements on optimisation and BAT should be seen as supplementary to the risk target, in providing evidence that the developer has taken into consideration, as far as reasonably possible, measures and options for reducing future doses and risks. Both principles focus on the proponent's work on developing

  5. Historical and social contexts for scientific writing and use of passive voice: Toward an undergraduate science literacy course

    Science.gov (United States)

    Ding, Dan Xiong

    The passive voice is a major stylistic feature of modern scientific discourse, but such a feature did not dominate scientific writing until the 1890s. It has its roots in the philosophical thoughts of experimental science of Francis Bacon and his followers such as Thomas Sprat and John Locke. In the early seventeenth century. Bacon called for a new science that emphasized collective knowledge of nature. Such a science was a cooperative and public enterprise in which scientists should work as a group to advance knowledge of nature. When science was moving gradually toward a public enterprise from the early seventeenth century, the passive voice gradually replaced the active voice in science writing as a dominant stylistic feature. The passive voice in scientific writing is thus historically and socially conditioned. Scientists take advantage of the linguistic functions of the passive voice to serve their rhetorical and pragmatic purposes such as presenting experiments as they are for others to reproduce and verify the results. It embodies two major conventions of scientific communities: (1) science is a public enterprise and (2) it is also a cooperative venture. Other conventions are related to these two: the collective authority of an scientific community is above the personal authority of any one individual scientist; science is not an infallible force, so any research result needs to be verified by a scientific community before it becomes knowledge; scientists use passive voice to approach their writing to make it appear as if it were objective; and science is a human profession. Therefore, we need to teach science students to use the passive voice, and more importantly, why and when to use it. We should emphasize writing practice to have students' see that they use passives rhetorically to present experimental processes, materials and methods.

  6. A review of the new provisions for sanctioning mentally disordered offenders in China, in a broader historical context.

    Science.gov (United States)

    Pei, Wei; van der Wolf, Michiel

    Reforms of the criminal justice system in China in recent years have included the 2012 Code of Criminal Procedure (CCP), which resulted in new disposals for mentally disordered offenders. From a Western perspective, changes in Chinese criminal law are sometimes clichéd as toothless window dressing, but they may represent a genuine step forward in safeguarding human rights. Taking a historical perspective, this paper reveals that in the East, as much as in the West, there is a 'moral tradition' of not punishing mentally disordered offenders who are not considered responsible for their acts. There are clear differences in disposal for those acquitted having been found 'not guilty by reason of insanity'. Whereas Western jurisdictions have offered (criminal) courts the opportunity for commitment in (forensic) mental hospitals from the early 19th Century, in China, disposal has remained, until the recent changes, the responsibility of the administration (mainly the police) or the family of the offender. A few high profile cases brought to light the inadequacy of these arrangements and the general disregard of obvious mental health issues when sentencing offenders. There was lack of clarity regarding who would take responsibility for treatment and issues of future public protection arising from a mental disorder. The 2012 CCP introduces the power of mental health commitment by the judiciary for those found non-responsible for an offense because of a mental disorder. Similar to provisions in Western jurisdictions there remain human rights concerns regarding aspects of 2012 CCP and the role of 'preventive detention' for mentally disordered offenders on indeterminate secure mental health detention. Nevertheless, the shift to judicial decision making in such cases and the possibility of mental health commitment are welcome steps in improving the human rights of this vulnerable population.

  7. Comparing Variance/Covariance and Historical Simulation in the Context of the Financial Crisis – Do Extreme Movements Have an Influence onto Portfolio Selection?

    Directory of Open Access Journals (Sweden)

    Svend Reuse

    2010-09-01

    Full Text Available Portfolio theory and the basic ideas of Markowitz have been extended in the recent past by alternative risk models as historical simulation or even copula functions. The central question of this paper is if these approaches lead to different results compared to the classical variance/covariance approach. Therefore, empirical data of the last 10 years is analysed. Both approaches are compared in the special context of the financial crisis. The worst case optimization and the Value at Risk (VaR are defined in order to define the minimum risk portfolio before and after the financial crisis. The result is that the financial crisis has nearly no impact onto the portfolio, but the two approaches lead to different results.

    Following the Second World War, the Food and Agriculture Organization (FAO) and the World Health Organization (WHO) teamed up to construct an International Codex Alimentarius (or 'food code') which emerged in 1963. The Codex Committee on Food Hygiene (CCFH) was charged with the task of developing microbial hygiene standards, although it found itself embroiled in debate with the WHO over the nature these standards should take. The WHO was increasingly relying upon the input of biometricians and especially the International Commission on Microbial Specifications for Foods (ICMSF) which had developed statistical sampling plans for determining the microbial counts in the final end products. The CCFH, however, was initially more focused on a qualitative approach which looked at the entire food production system and developed codes of practice as well as more descriptive end-product specifications which the WHO argued were 'not scientifically correct'. Drawing upon historical archival material (correspondence and reports) from the WHO and FAO, this article examines this debate over microbial hygiene standards and suggests that there are many lessons from history which could shed light upon current debates and efforts in international food safety management systems and approaches.

    Full Text Available The split into the predominantly Muslim Northern Sudan, and Southern Sudan with a Christian and animist majority, had been emerging in the course of many centuries. Without any doubt, one is bound to mention the natural and geographical boundaries, the ethnical diversity of the regions, the influence exercised during the centuries by the Egyptians, Arabs and later on by the British. According to the opinions of some experts on the subject, there can be two distinct matters that have contributed to the split of the North and the South. These were education and religion. Apart from education, also the issue of religion was dividing the Sudan. After the declaration of independence on January 1, 1954 all the Christian private schools in the South were closed down. There remained only state schools with Arabic as the language of instruction and with the upbringing model based on the Koran teaching. Having obtained political independence, the fears of the British administration and Christian missionaries became a reality: Islam was made the state religion. The only way to attain an occupational and social status was to convert to Islam. Frequently, this took place according to the rule of an already accomplished fact or by pressure. In the context of Sudan, one of the biggest country in Africa, with its population of over 37 million, made up of 70 per cent Muslim believers , 14 per cent of Christians, and 12 per cent of animists, it is of great importance for the perception of fundamentalism to be familiar with the history of this country.

    On the basis of this, this research investigates the historical context of one of the shared tales of Mathnavi and Fihe Mafih, that is, Nazar Kardane Peighambar be Asiran, and proposes this idea that commentators are divided into three groups due to their negligence of Molavi’s techniques: 1 those who consider the battle of Badr as the historical context of the tale, 2 those who consider the battles of Bani Nazir and Bani Ghorayze as the historical context of that tale, 3 those who are silent on this issue. While analyzing the ideas of commentators, the reasons behind their mistake in two issues are explained: 1 similar tale in Fihe Mafih, 2 the structure of the tale and the creativity of Molavi.

    Full Text Available . The article presents an analysis of the way public debt operates in Romania, in the context of states economies trends, of complex and topical financial environments. In the context of a functional market economy, the issues faced by certain states involving high public debt levels or potential budgetary pressure risks converge towards the idea that public finances sustainability needs to be a major challenge at the level of public policies. Considering this situation, the adequate policies to tackle public finances sustainability need to have, as a launching base, the overall strategy of the European Union, focused on the three component parts, namely abatement of public debt, increasing productivity and employment and last but not least, reforming the pension and healthcare systems. To ensure reasonably sustainable public debt levels, EU member states need to attain medium term strategic budgetary objectives, that would ensure a downward trend of public debt, a condition which can be fulfilled by compliance with budget policies rules, which ground development in the macroeconomic framework.

    2018-02-01

    Children's health is influenced by the context in which they live. We provide a descriptive essay on the status of children in rural America to highlight features of the rural environment that may affect health. We compiled information concerning components of the rural environment that may contribute to health outcomes. Areas addressed include the economic characteristics, provider availability, uniquely rural health risks, health services use, and health outcomes among rural children. Nearly 12 million children live in the rural United States. Rural counties are economically disadvantaged, leading to higher rates of poverty among rural versus urban children. Rural and urban children are approximately equally likely to be insured, but Medicaid insures a higher proportion of children in rural areas. While generally similar in health, rural children are more likely to be overweight or obese than urban children. Rural parents are less likely to report that their children received preventive medical or oral health visits than urban parents. Rural children are more likely to die than their urban peers, largely due to unintentional injury. Improving rural children's health will require both increased public health surveillance and research that creates solutions appropriate for rural environments, where health care professionals may be in short supply. Most importantly, solutions must be multisectoral, engaging education, economic development, and other community perspectives as well as health care. © 2016 National Rural Health Association.

    Full Text Available Globalization represents a controversial phenomenon both because of its complexity and because of the various implications it has on the global economy. Globalization will act simultaneously on many levels, its effects being correlated with the diversity of the angles from which this phenomenon can be approached from – economic, social, politic, cultural, philosophic etc. The article represents an incursion into the issue regarding the implications and effects of globalization grouped in several areas of analysis such as the disappearance of borders, the effects on culture, the effects on the education, the impact on labour market impact and the phenomenon of immigration, the effects of globalization in the context of the food crisis underdevelopment and poverty. To complete the analysis that points out enough elements considered to be negative, at the end of the article, there are also approached the development opportunities that globalization can offer in terms of boosting the economic exchanges, the exchange of genuine cultural values and ensuring a transfer of information at a global scale, so necessary for the scientific and technological progress.  The conclusions of the article weighs the many aspects highlighted, both negative and positive, and suggests a series of useful research directions in order to fathom the complex features of this concept so controversial – globalization.

Yet their strategic contribution and the value they add remain unrecognised. Research purpose: The main objective of this research was to explore the extent to which HR practitioners are currently allowed to display HR competencies in the workplace, and whether any significant differences exist between perceived HR competencies, based on the respondents’ demographic characteristics. Motivation for the study: Limited empirical research exists on the extent to which HR practitioners are allowed to display key competencies in the South African workplace. Research approach, design, and method: A quantitative research approach was followed. A Human Resource Management Professional Competence Questionnaire was administered to HR practitioners and managers (N = 481. Main findings: The results showed that HR competencies are poorly applied in selected South African workplaces. The competencies that were indicated as having the poorest application were talent management, HR metrics, HR business knowledge, and innovation. The white ethic group experienced a poorer application of all human research management (HRM competencies compared to the black African ethnic group. Practical/managerial implications: The findings of the research highlighted the need for management to evaluate the current application of HR practices in the workplace and also the extent to which HR professionals are involved as strategic business partners. Contribution/value-add: This research highlights the need for the current application of HR competencies in South African workplaces to be improved.

  4. The Ethics of Big Data: Current and Foreseeable Issues in Biomedical Contexts.

    Mittelstadt, Brent Daniel; Floridi, Luciano

    2016-04-01

    The capacity to collect and analyse data is growing exponentially. Referred to as 'Big Data', this scientific, social and technological trend has helped create destabilising amounts of information, which can challenge accepted social and ethical norms. Big Data remains a fuzzy idea, emerging across social, scientific, and business contexts sometimes seemingly related only by the gigantic size of the datasets being considered. As is often the case with the cutting edge of scientific and technological progress, understanding of the ethical implications of Big Data lags behind. In order to bridge such a gap, this article systematically and comprehensively analyses academic literature concerning the ethical implications of Big Data, providing a watershed for future ethical investigations and regulations. Particular attention is paid to biomedical Big Data due to the inherent sensitivity of medical information. By means of a meta-analysis of the literature, a thematic narrative is provided to guide ethicists, data scientists, regulators and other stakeholders through what is already known or hypothesised about the ethical risks of this emerging and innovative phenomenon. Five key areas of concern are identified: (1) informed consent, (2) privacy (including anonymisation and data protection), (3) ownership, (4) epistemology and objectivity, and (5) 'Big Data Divides' created between those who have or lack the necessary resources to analyse increasingly large datasets. Critical gaps in the treatment of these themes are identified with suggestions for future research. Six additional areas of concern are then suggested which, although related have not yet attracted extensive debate in the existing literature. It is argued that they will require much closer scrutiny in the immediate future: (6) the dangers of ignoring group-level ethical harms; (7) the importance of epistemology in assessing the ethics of Big Data; (8) the changing nature of fiduciary relationships that

    The current article analyzes the figure of the American bioethicist James Drane (1930). Drane not only played a crucial role in the birth of Bioethics in the United States, but was also instrumental in the inception and development of the field in Spain and Latin America. His «sliding scale» was the first dynamic tool encouraging a systematic evaluation of a patient's capacity to make healthcare-related decisions. However Drane's major contribution to the field was his application of virtue Ethics to the doctor-patient relationship. His proposal rests on the physician's compromise with the patient in all his/her dimensions. This goal will guide the physician's character and serve as compass, with which to exercise a virtuous practice, since only by exercising these virtues can doctors become truly good.

    The author investigates the clinical affinity between Klein and Winnicott (1935-46) asa way to historically situate Winnicott 's later criticism of Klein's 'temperamental' inability to understand the impact of the environment on the infant's development. By setting out Klein s theories at the time when Winnicott began supervision with her in 1935, a context is established for the analysis of an unpublished 1937 manuscript by Klein ('Notes on baby'). The author argues that this direct and extensive infant observation demonstrates Klein's sensitivity to the familial environment. While Winnicott as a paediatrician showed enthusiasm for Klein s ideas, he also demonstrated a difference of opinion in emphasising the maternal environment of provision after his wartime evacuation experiences with London children. The factors leading to their mutual distancing are outlined as follows: (1) the post-Controversial Discussion atmosphere of the British Psycho-Analytical Society in 1944. The new non-aligned psychoanalytic 'middle group' allowed Winnicott to take a pick and choose attitude towards available analytic theories; (2) Winnicott us new clinical practices and theory differed from Klein 's, leading to a widening gap between 1946 and 1951. Winnicott's new theory and practice simultaneously represented his technical marginalisation of Klein s emphasis on the direct analysis of the patient s destructiveness by the time he delivered the 'Transitional objects' paper in 1951.

    Full Text Available Current phosphorus (P use in European countries is highly dependent on mineral P imports and not sustainably managed. In order to identify and implement measures for sustainable P management, a comprehensive understanding of national P flows and stocks and their temporal dynamics is essential. We conduct a substance flow analysis (SFA of the Swiss P system of the year 2015, and study the dynamics of the national P system by looking into its development since 1989. Furthermore, we investigate how political-legislative interventions affected the P system during this period. The results show that between 1989 and 2015, the P efficiency in Swiss agriculture increased from 59% to 94%, mainly due to a considerable reduction of fertilization in the agricultural subsystem. At the same time, Switzerland's P import dependency decreased from 33% to 24% between 1989 and 2002 because of a reduction of mineral fertilizer import and use. Between 2002 and 2015, the import dependency stagnated because further improvements in P use efficiency in agriculture were outweighed by a decrease of P recycling and an increase of P losses in the waste management system. By embedding these temporal dynamics in their political-legislative context, we found that top-down interventions such as incentives for a balanced nutrient budget in agriculture, restrictions of the use of animal by-products in the agri-food system or the ban of direct sewage sludge recycling in agriculture significantly affected and shaped the national P system. Our analysis provides profound quantitative and qualitative insights into past and present P management in Switzerland and is followed by part 2 of the paper, where we analyze possible future pathways of P management.

  10. On the Need for Rethinking Current Practice that Highlights Goal Achievement Risk in an Enterprise Context.

    Science.gov (United States)

    Aven, Eyvind; Aven, Terje

    2015-09-01

    This article addresses the issue of how performance and risk management can complement each other in order to enhance the management of an enterprise. Often, we see that risk management focuses on goal achievements and not the enterprise risk related to its activities in the value chain. The statement "no goal, no risk" is a common misconception. The main aim of the article is to present a normative model for describing the links between performance and risk, and to use this model to give recommendations on how to best structure and plan the management of an enterprise in situations involving risk and uncertainties. The model, which has several novel features, is based on the interaction between different types of risk management (enterprise risk management, task risk management, and personal risk management) and a structure where the enterprise risk management overrules both the task and personal risk management. To illustrate the model we use the metaphor of a ship, where the ship is loaded with cash-generating activities and has a direction over time determined by the overall strategic objectives. Compared to the current enterprise risk management practice, the model and related analysis are founded on a new perspective on risk, highlighting knowledge and uncertainties beyond probabilities. © 2015 Society for Risk Analysis.

    Patient motion is an important consideration in modern PET image reconstruction. Advances in PET technology mean motion has an increasingly important influence on resulting image quality. Motion-induced artifacts can have adverse effects on clinical outcomes, including missed diagnoses and oversized radiotherapy treatment volumes. This review aims to summarize the wide variety of motion correction techniques available in PET and combined PET/CT and PET/MR, with a focus on the latter. A general framework for the motion correction of PET images is presented, consisting of acquisition, modeling, and correction stages. Methods for measuring, modeling, and correcting motion and associated artifacts, both in literature and commercially available, are presented, and their relative merits are contrasted. Identified limitations of current methods include modeling of aperiodic and/or unpredictable motion, attaining adequate temporal resolution for motion correction in dynamic kinetic modeling acquisitions, and maintaining availability of the MR in PET/MR scans for diagnostic acquisitions. Finally, avenues for future investigation are discussed, with a focus on improvements that could improve PET image quality, and that are practical in the clinical environment. © 2017 American Association of Physicists in Medicine.

  12. SOME CONSIDERATIONS ON LOCAL FINANCIAL AUTONOMY IN THE CONTEXT OF THE CURRENT FINANCIAL CRISIS

    Full Text Available Financing of local authorities is currently at the Centre of the political discourse is a daily concern. Romania faces, usually with an attempt to offset the need for control and reduction of public spending with greater financial autonomy of local authorities. At the time, it was searched and searches for a path, a means to achieve a fair distribution of financial resources between the various levels of administration, budget reductions to all of them. If strengthening democracy means to strengthen local autonomy, then it means you have created a system for financing local authorities to be efficient, fair and pointing towards the economic needs of States. In other words, decentralization and local financing and the principle of subsidiarity are mutually dependent. Rightly, the decentralisation of financial management is considered to be the "backbone" of the administrative system of decentralisation, the financial resources being those which are operational link between the needs of local communities and the rules necessary to satisfy them. Thus, the lack of financial resources of the local self-government can result in failure to meet the needs of its members, which at the same time failure of administrative decentralization. The decentralisation of financial management can also be seen as the Government of some specific functions on the line of management authority and the tax revenue to the local public authorities.

    In 2008, between 129,000 and 194,000 of the 430,000 pediatric HIV infections worldwide were attributable to breastfeeding. Yet in many settings, the health, economic, and social consequences of not breastfeeding would have dire consequences for many more children. In the first part of this review we provide an overview of current knowledge about infant feeding in the context of HIV. Namely, we describe the benefits and risks of breastmilk, the evolution of recommended infant feeding modalities in high-income and low-income countries in the last two decades, and contextualize the recently revised guidelines for infant feeding in the context of HIV current knowledge. In the second section, we suggest areas for future research on the postnatal prevention of mother-to-child transmission of HIV (PMTCT) in developing and industrialized countries. We suggest two shifts in perspective. The first is to evaluate PMTCT interventions more holistically, to include the psychosocial and economic consequences as well as the biomedical ones. The second shift in perspective should be one that contextualizes postnatal PMTCT efforts in the cascade of maternal health services. We conclude by discussing basic, clinical, behavioral, and programmatic research questions pertaining to a number of PMTCT efforts, including extended postnatal ARV prophylaxis, exclusive breastfeeding promotion, counseling, breast milk pasteurization, breast milk banking, novel techniques for making breast milk safer, and optimal breastfeeding practices. We believe the research efforts outlined here will maximize the number of healthy, thriving, HIV-free children around the world.

    Some studies done in Asian patients have shown that serum levels of hepatitis B virus (HBV) DNA predict the development of cirrhosis. However, it is unclear whether this also applies for non-Asian patients. This study investigated historic and current HBV DNA and quantitative hepatitis B surface antigen (HBsAg) levels as predictors of cirrhosis in non-Asian women with chronic HBV. A retrospective cohort study of non-Asian women with chronic HBV was performed. Among other variables, HBV DNA and quantitative HBsAg levels were measured in stored historic serum samples obtained during pregnancy (period 1990-2004) and current serum samples (period 2011-2012) to determine any association with liver cirrhosis by liver stiffness measurement (LSM). One hundred and nineteen asymptomatic, treatment-naïve non-Asian women were included; the median number of years between the historic sample and the current sample was 17 (interquartile range (IQR) 13-20). The median historic log HBV DNA and quantitative log HBsAg levels were 2.5 (IQR 1.9-3.4) IU/ml and 4.2 (IQR 3.6-4.5) IU/ml, respectively. LSM diagnosed 14 patients (12%) with F3-F4 fibrosis, i.e. stiffness >8.1kPa. No association of cirrhosis was found with historic HBV DNA (relative risk (RR) 0.34, 95% confidence interval (CI) 0.05-2.44) or with the quantitative HBsAg level (HBsAg level >1000 IU/ml, RR 0.35, 95% CI 0.11-1.11). Multivariable analysis identified alcohol consumption (odds ratio (OR) 6.4, 95% CI 1.3-30.1), aspartate aminotransferase >0.5 times the upper limit of normal (OR 15.4, 95% CI 1.9-122.6), and prothrombin time (OR 12.0, 95% CI 1.2-120.4), but not HBV DNA or quantitative HBsAg level, to be independent predictors of the presence of cirrhosis. Neither historic nor current HBV DNA or the quantitative HBsAg level is associated with the development of HBV-related cirrhosis in non-Asian women. Copyright © 2014 The Authors.

  16. Teaching the content and context of science: The effect of using historical narratives to teach the nature of science and science content in an undergraduate introductory geology course

    Science.gov (United States)

    Vanderlinden, David Winston

    This study reports the use of historically accurate narratives (short stories) to simultaneously teach geology content and the nature of science in an introductory, undergraduate geology course. The stories describe key events involved in the development of geologists' ideas about continental drift/plate tectonics and deep time/the age of the Earth. The design of the stories provides a highly contextualized setting which is designed to promote NOS and geology understanding by explicitly attending students to fundamental concepts and requiring students to reflect on the short story content. Evidence is reported to support the conclusion that students using these short stories constructed a better understanding of (1) the variety of processes involved in the construction of scientific knowledge, (2) the subjective nature of data that allows it to be interpreted differently by different scientists, and (3) the roles that culture and society play in determining the way in which scientific work is conducted and scientific ideas are constructed, while maintaining equal levels of understanding of geology content when compared to students who did not use the short stories. In some cases, students' preconceptions about objectivity in science, the degree to which scientific ideas can be considered as "proven" or "true," and the role of discovery in science appear to have adversely affected their ability to interpret the short story content in the ways intended. In addition, students' misconceptions about differences in how oceanic and continental plates were formed and geologists' use of relative and absolute dating techniques, especially the appropriate uses of radio-isotopic dating, are described. This study has implications for science instructors as they make efforts to efficiently use class time and curriculum resources to teach about the both the content and context of science and for geology instructors as they consider students' misconceptions about plate tectonics

    Full Text Available Germany and Russia share a strong economic interdependence, Germany being presently the largest importer of Russian gas. At the time of writing, the on-going conflict between Ukraine and Russia, compounded with economic sanctions imposed on Russia by the European Union, has raised concerns about Russia as a reliable gas supplier. This article analyses Germany’s dependence on Russian gas within the present economic and political contexts and assesses a the most plausible course of action of German energy policy, taking into account Germany’s current role as a gas transit country; and b the impact of the present context on the shaping of Germany’s foreign policy towards Russia. It is concluded that energy policy measures will not enable drastic reductions in Germany’s dependence on Russian gas in the short term and, moreover, that no abrupt change of direction in German foreign policy towards Russia is to be expected.

    Isabel Virginia de Alencar Pires

    2011-07-01

    Full Text Available Este artigo aborda o livro "A hora da estrela", de Clarice Lispector, à luz dos pressupostos da Teoria da Recepção, de Jauss, que leva em conta o contexto histórico nas análises literárias. Publicada em fins de 1977, essa obra – que conta a história de Macabéa, uma nordestina que, “sem saber como nem por que”, acaba indo morar no “inacreditável Rio de Janeiro” – é considerada por diversos estudiosos como a “mais explicitamente social” da autora, pois até então os livros clariceanos costumavam ser recorrentemente acusados pela crítica da época de se “alhearem” da realidade, dedicando-se predominantemente a abordagens de caráter psicológico e deixando de lado o contexto político e social. Em A hora da estrela, a temática social passa a ser mais explícita, verificando-se assim uma espécie de “ruptura” na trajetória literária clariceana, interrompida no mesmo ano de publicação da obra, com a morte da autora. Este artigo busca apreender, nas entrelinhas do texto, as marcas que o diálogo do último livro lançado em vida pela escritora, durante o período do autoritarismo brasileiro, realiza com o seu contexto de surgimento. Para tanto, o estudo faz ainda uma aproximação entre o último livro de Clarice Lispector e o cinema de Glauber Rocha. This article contemplates Clarice Lispector’s “A hora da estrela” (The Hour of the Star, based on Jauss´ Reception Theory, which takes into account the historical context in literary analyses. Published in late 1977,  this work – which tells the story of Macabéa - a natural born northeast Brazilian woman that “not knowing why or how” moves to the “unbelievable city of Rio de Janeiro” – is considered by many scholars the “most explicitly social” one  done by the author. Up to that moment, her books had frequently been accused by critics of “deviating” from reality, focusing predominantly on psychological features and leaving social

    New risks in nosocomial infections and the dramatic increase in antibiotic-resistant pathogens in healthcare facilities have pointed to the urgent need for a good education of students and practitioners in the basics of hospital hygiene and infection prevention. On the other hand in the last 10 years a large number of institutes of hygiene in universities were closed with remarkable consequences concerning the decreased education in modern hygiene and public health. A broad historical overview over the last 200 years of teaching hygiene and public health at German universities is given which was integrated into the education of medical students. Nowadays many universities do not teach modern hygiene and public health. The demand of re-establishing new institutes of hygiene by the German Medical Council is discussed. The curriculum for the formation of hospital hygienists is presented.

    2016-06-01

    The current neoliberal context of schools presents difficult challenges in addressing persistent issues of social inequalities. In this article, first, I argue that because of today's market-driven education, the rise of fitness testing in school physical education (PE) can be seriously detrimental to young people in general and to ethnic-minority young people's embodied identity in particular. Second, I explain how the racialization process circulated by the body-at-risk discourse, sustained by the media, and reproduced by high-stakes testing in PE forces ethnic-minority young people to construct their identities through White eyes, which alienates them from a consciousness of their own identity. Third, I explore the possible uses and pitfalls of Spivak's theoretical notion of "strategic essentialism" to put forward strategies to build a positive image of the "other" while attempting to avoid the erasure of difference. Fourth, I conclude the article by suggesting how Spivak's notion of strategic essentialism can be useful in rethinking current PE fitness practices.

    Full Text Available This article aims at analyzing the current role of civil society organized in improving the democratic setup of the Brazilian State. To this end, it has been shown through a literature review and application of the hypothetical deductive method, the evolution and the current application of the concepts of Democracy and Third Sector. As a specific objective it was conceptually demonstrated what democracy stand for, its function today, collating classic and current authors. The theoretical construction of the classic constitutional paradigms and the need for realization of the democratic rule of law now has been shown. The concepts of the Third Sector and its function of acting as an effective instrument of social change were also analyzed. Finally, it is concluded that the third sector is an instrument that seeks the realization of current Brazilian democracy, besides having a role of service provider that would imminently be a responsibility from the State.

    Full Text Available Background Why biodiversity is not uniformly distributed on the Earth is a major research question of biogeography. One of the most striking patterns of disparity in species distribution are the biodiversity hotspots, which generally do not fit with the distribution of relevant components of the Neotropical biota. In this study, we assess the proximal causes of the species-richness pattern of one of the most conspicuous groups of Neotropical mammals, the New World monkeys the Platyrrhini. We test two complementary hypotheses: (1 there is a historical source-sink dynamic (addressed using macroevolutionary and macroecological approaches; (2 the large number of species in the Amazon basin is due to the constraints imposed by environmental variables occurring outside this area. Methods We first characterize spatial patterns of species richness and biodiversity hotspots using a new, objective protocol based on probabilities. Then we evaluate the source-sink hypothesis using BioGeoBEARS analysis and nestedness analysis of species richness patterns. Complementarily, to measure how often different species pairs appear in the same sites, we used null models to estimate the checkerboard score index (C-score. Finally, we evaluate the relationship between several climatic variables and species richness through ordinary least squares (OLS and spatial autoregressive (SAR models, and the potential environmental constraints on the pattern. Results We found one significant cluster of high values for species richness in the Amazon basin. Most dispersal events occurred from the Amazonian subregion to other Neotropical areas. Temperature (T, discrepancy (BR, and NODF indexes show a significant nesting in the matrix ordered by species richness and available energy. The C-score observed was significantly smaller than the null expectation for all sites in the Neotropics where there are records of platyrrhine species. Ten climatic variables comprised the best

    Santa Cruz Island is the largest of the northern Channel Islands located off the coast of California. It is owned and managed as a conservation reserve by The Nature Conservancy and the Channel Islands National Park. The island is home to nine plant taxa listed in 1997 as threatened or endangered under the federal Endangered Species Act, because of declines related to nearly 150 years of ranching on the island. Feral livestock were removed from the island as a major conservation step, which was part of a program completed in early 2007 with the eradication of pigs and turkeys. For the first time in more than a century, the rare plants of Santa Cruz Island have a chance to recover in the wild. This study provides survey information and living plant materials needed for recovery management of the listed taxa. We developed a database containing information about historical collections of the nine taxa and used it to plan a survey strategy. Our objectives were to relocate as many of the previously known populations as possible, with emphasis on documenting sites not visited in several decades, sites that were poorly documented in the historical record, and sites spanning the range of environmental conditions inhabited by the taxa. From 2003 through 2006, we searched for and found 39 populations of the taxa, indicating that nearly 80 percent of the populations known earlier in the 1900s still existed. Most populations are small and isolated, occupying native-dominated habitat patches in a highly fragmented and invaded landscape; they are still at risk of declining through population losses. Most are not expanding beyond the edges of their habitat patches. However, most taxa appeared to have good seed production and a range of size classes in populations, indicating a good capacity for plant recruitment and population growth in these restricted sites. For these taxa, seed collection and outplanting might be a good strategy to increase numbers of populations for species

  6. The under-representation of African American women in the STEM fields within the academy: A historical profile and current perceptions

    Howard, Tenisha Senora

    This research project seeks to discover the reasons behind the underrepresentation of African American women (AAW) in higher education, particularly in the Science Technology Engineering and Mathematics fields. Why is there underrepresentation of AAW in the STEM fields? Research evidence has demonstrated that AAW face social disparities such as race, gender, and class in the academy. A lack of adequate mentoring and financial resources to support their research efforts are related to these disparities and present fundamental challenges for them. To conduct the inquiry about the barriers AAW have to overcome to achieve success in STEM disciplines, a qualitative research method was used to "attend to social, historical, and temporal context. The findings of these studies are tentatively applied; that is, they may be applicable in diverse situations based on comparability of other contexts" (Mariano, 1995, p. 464). The researcher collected data by conducting in-depth interviews with five participants, using an open-ended conversational format to facilitate the development of trust, rapport, and maximum elicitation of stories from the participants. The results suggest that AAW overcome barriers to successful STEM careers through their family and social ties, mentoring relationships as well as their religious practices.

    Since 1982 withdrawals from the Boise Geothermal aquifer system have increased from less than 300 million to over 600 million gals/yr. Prior to 1983 the system appears to have been in or near equilibrium. Current production levels exceed the ability of the system to recover on an annual basis. Potentiometric levels within the aquifer are declining at increasing rates and a new equilibrium level is not evident. Thus, exploitation of the geothermal aquifer is currently outstripping knowledge and understanding of the aquifer. It is time to give serious consideration to placing a temporary moratorium on further development and production from the system until a better understanding of its capacity is achieved.

    Radioactive iodine (RAI, 131 I) has been used as a therapeutic agent for differentiated thyroid cancer (DTC) with over 50 years of history. Recently, it is now attracting attention in medical fields as one of the molecular targeting therapies, which is known as targeted radionuclide therapy. Radioactive iodine therapy (RIT) for DTC, however, is now at stake in Japan, because Japan is confronting several problems, including the recent occurrence of the Great East Japan Disaster (GEJD) in March 2011. RIT for DTC is strictly limited in Japan and requires hospitalization. Because of strict regulations, severe lack of medical facilities for RIT has become one of the most important medical problems, which results in prolonged waiting time for Japanese patients with DTC, including those with distant metastasis, who wish to receive RIT immediately. This situation is also due to various other factors, such as prolonged economic recession, super-aging society, and subsequent rapidly changing medical environment. In addition, due to the experience of atomic bombings in Hiroshima and Nagasaki, Japanese people have strong feeling of ''radiophobia ''. There is fear that GEJD and related radiation contamination may worsen this feeling, which might be reflected in more severe regulation of RIT. To overcome these difficulties, it is essential to collect and disclose all information about the circumstances around this therapy in Japan. In this review, we would like to look at this therapy through several lenses, including historical, cultural, medical, and socio-economic points of view. We believe that clarifying the problems is sure to lead to the resolution of this complicated situation. We have also included several recommendations for future improvements. (author)

    Social practice theory has brought new perspectives to ‘sustainable consumption’ studies in terms of both conceptual developments and rich empirical research. One appealing and shared understanding is that practices change over time, suggesting that shifts away from current unsustainable practices toward more environmentally sound and socially just alternatives are possible. Much work has focused on how to recruit new practitioners to more ‘sustainable’ practices (Jack 2013; Plessz et al. 201...

  12. Historizing epistemology in psychology.

    2010-12-01

    The conflict between the psychometric methodological framework and the particularities of human experiences reported in psychotherapeutic context led Michael Schwarz to raise the question whether psychology is based on a methodological error. I take this conflict as a heuristic tool for the reconstruction of the early history of psychology, which bears witness to similar epistemological conflicts, though the dominant historiography of psychology has largely forgotten alternative conceptions and their valuable insights into complexities of psychic phenomena. In order to work against the historical amnesia in psychology I suggest to look at cultural-historical contexts which decisively shaped epistemological choices in psychology. Instead of keeping epistemology and history of psychology separate, which nurtures individualism and naturalism in psychology, I argue for historizing epistemology and for historical psychology. From such a historically reflected perspective psychology in contemporary world can be approached more critically.

  14. Examining historical and current mixed-severity fire regimes in ponderosa pine and mixed-conifer forests of western North America.

    Dennis C Odion

    Full Text Available There is widespread concern that fire exclusion has led to an unprecedented threat of uncharacteristically severe fires in ponderosa pine (Pinus ponderosa Dougl. ex. Laws and mixed-conifer forests of western North America. These extensive montane forests are considered to be adapted to a low/moderate-severity fire regime that maintained stands of relatively old trees. However, there is increasing recognition from landscape-scale assessments that, prior to any significant effects of fire exclusion, fires and forest structure were more variable in these forests. Biota in these forests are also dependent on the resources made available by higher-severity fire. A better understanding of historical fire regimes in the ponderosa pine and mixed-conifer forests of western North America is therefore needed to define reference conditions and help maintain characteristic ecological diversity of these systems. We compiled landscape-scale evidence of historical fire severity patterns in the ponderosa pine and mixed-conifer forests from published literature sources and stand ages available from the Forest Inventory and Analysis program in the USA. The consensus from this evidence is that the traditional reference conditions of low-severity fire regimes are inaccurate for most forests of western North America. Instead, most forests appear to have been characterized by mixed-severity fire that included ecologically significant amounts of weather-driven, high-severity fire. Diverse forests in different stages of succession, with a high proportion in relatively young stages, occurred prior to fire exclusion. Over the past century, successional diversity created by fire decreased. Our findings suggest that ecological management goals that incorporate successional diversity created by fire may support characteristic biodiversity, whereas current attempts to "restore" forests to open, low-severity fire conditions may not align with historical reference conditions in

    Full Text Available The article is aimed at researching the historical evolution and a current interpretation of the definition of essence of the category of «competitiveness of enterprise of the automobile industry». Using the monographic analysis, the article reviews the historical evolution of the definition of essence of the category of «competitiveness of enterprise» in the national scientific literature in the period from 2007 to 2016. It has been concluded that the essence of the concept of «competitiveness of enterprise» is actually reduced to the competitiveness of products or operational efficiency. The author’s own definition of the essence of the category of «competitiveness of enterprise of the automobile industry» has been suggested: it has been specified that under the given term be understood «...the dynamic ability of enterprise of the automobile industry to ensure the efficiency of all activities as result of interaction of the internal competitive potential and the external competitive environment factors in accordance with the chosen competitive strategy at a certain stage of the life cycle».

    Conclusions of the research: Estimating the M. M. Kovalevsky’s efforts in the methodology of historical and legal comparative study it should be noted that the attitude to his method in the scientific community is controversial. While agreeing, in general, with a positive appreciation of the M. M. Kovalevsky’s scientific heritage it should be pointed that the scientist first qualitatively tried to develop theoretical and methodological basis for the historical and comparative method in the domestic comparative study. Despite the fact that while theoretically reasoning his own method, M. M. Kovalevsky lacked modern structural and functional approach, but in most cases he was able to aptly describe the individual elements of the theory, methods and technique of the new means of special and scientific knowledge.

    The aims of our study were to describe the history and development of intracavitary brachytherapy in the treatment of gynecological tumors, to introduce our current practice for intracavitary brachytherapy treatments based on CT planning. Gynecological intracavitary brachytherapy has been applied in our department since the early 1930s. After a long development it has been completely renewed by 2014. In our center definitive and/or preoperative gynecological HDR-AL brachytherapy treatments were given to 25 patients (13 corpus uterine cancer patients and 12 cervical cancer patients) during the period of 01. 01. 2014-31. 01. 2015. In each case, target volumes were planned by CT images, DVH (dose volume histogram) analysis was performed in order to calculate the radiation tolerance dose of rectum and urinary bladder. Evaluation was performed by the EclipseTM 11.0.47. brachytherapy treatment planning system. During the definitive treatments of the 13 uterine cancer patients the D2cc value related to rectum tolerance was 66.3 GyEQD2 (46-91 Gy). The average D2cc value of urinary bladder tolerance was 76.5 GyEQD2 (30-112 Gy). CI was 0.72 (0.6-0.95). Average value of COIN was 0.57 (0.35-0.78). Compared to the prescribed dose D100 and D90 values were given in ratios. Compared to the volume which receives 100% of reference dose V150 and V200 values were also given in ratios. D100 and D90 were calculated to be 0.66 (0.47-0.97) and 0.91 (0.8-1.25). V150 and V200 volumes were 0.11 (0.04-0.18) and 0.06 (0.02-0.1). During the definitive treatments of 12 cervical cancer patients the D2cc value related to rectum tolerance calculated by DVH was 75.2 GyEQD2 (60-82 Gy). The average D2cc value of urinary bladder tolerance was 85 GyEQD2 based on DVH. CI was 0.66 (0.42-0.76). Average value of COIN was 0.52 (0.32-0.78). Mean value of DHI was 0.46 (0.27-0.54). D100 and D90 were calculated to be 0.72 (0.57-0.89) and 0.91 (0.84-1.11). V150 and V200 volumes were 0.057 (0.02-0.13) and 0.02 (0

    Full Text Available The Anglo-Saxon model of employment has certain features that derive from the specificity of the political and economic system of Great Britain. The labour market policies in the United Kingdom were different depending on the historical and political period; however, the Anglo-Saxon model is characterized mainly by high flexibility but low security. This paper presents the main features of the Anglo-Saxon model of employment, compared to the Nordic and the Mediterranean model and shows Britain's economic situation before and after the crisis.

  1. Should the definition of "sleep hygiene" be antedated of a century? A historical note based on an old book by Paolo Mantegazza, rediscovered. To place in a new historical context the development of the concept of sleep hygiene.

    Science.gov (United States)

    Gigli, Gian Luigi; Valente, Mariarosaria

    2013-05-01

    The article contains a historical note on the concept of sleep hygiene, developed in 1977 by Peter Hauri, who developed a set of sleep-promoting rules, considered the fundament for sleep-hygiene techniques. Somnologists, unanimously ascribed to Hauri the fatherhood of the lucky term, while numerous books included at least a section on sleep hygiene. "Inadequate sleep hygiene" was included as a nosological entity in the International Classification of Sleep Disorders. This article intends to demonstrate that the concept of sleep hygiene was developed many years before, thanks to the pioneering work of Paolo Mantegazza, a scientist and a professor in the Medical School of the University of Pavia, Italy. After presenting briefly the history of the University of Pavia and illustrating the profile of Paolo Mantegazza, the article presents the original book published by Mantegazza in 1864 (second edition in 1865). The authors report extensive citations of Mantegazza's original book dealing with sleep hygiene. Mantegazza's indications, compared with Hauri's rules show important similarities. The authors support the view that the fatherhood of sleep hygiene should be acknowledged to Mantegazza and antedated to 1864. Hauri keeps the merit of giving more solid scientific roots to the concept of sleep hygiene and of inserting it in the frame of modern sleep medicine.

    Full Text Available Traditional medicines still prevail in current Malagasy context. A careful historical analysis shows however that Malagasy traditional medicine has been screened through many filters before being accepted in a global context. Traditional medicine in its authentic form has been more or less rejected with the advent of  modern medicine – although not without reaction. This paper will retrace the historical encountering of the modern and traditional to determine the extent to which traditional medicine is acknowledged and used in the current prevailing modern, rational and scientific global context.

    Full Text Available Polymorphism of Y-chromosome is an interdisciplinary science which aims to answer historical questions related to the peoples’ ethnogenesis on the basis of population genetic research . Scientific research of Y-chromosome polymorphism began at the end of 1990s. Studies of Y-chromosome polymorphism represent only part of population genetic researches. In 2002 there was introduced a single standard regarding SNP-tree mutations and names haplogroups (consortium of Y-chromosome. Prior to this there was no less than 5 different classifications haplogroups. About this time, the National Genographic Project have been started, which purpose was to explore all the world populations by STR (short tandem repeats and SNP (single nucleotide polymorphism mutations of Y-chromosome. The basis is the principle of geographical residence. The results of research of the participants of this project resulted in hundreds of articles on the ethnogenesis of different nations of the earth published in journals specialized in population genetics, mainly in the English. In this article, the author presents his view on the methodological problems related to establishing of new application of historical science (the study of polymorphism of the Y-chromosome. The article contains descriptions and examples of faulty research and methodological mistakes. The author also addressed the issue of historiography of the study of the ethnogenesis of the Turkic peoples of Eurasia and methods of population genetics identifying the tools and methods for the study of Y-chromosome polymorphism. This article describes the methods of population genetics such as cluster analysis, phylogenetic networks, multidimensional scaling, calculation of “genetic” distances, TMRCA.

    Full Text Available Confrontations with threats and challenges to the existence of governments and societies have marked the flow of time throughout history. Present and future threats associated, as they are, with historical and traditional challenge are, in many places, of such complexity that they already require new forms of relations between civilian authorities and the leadership of professional institutions dedicated to defense and security. These new relations will have to be based on an understanding of the processes of democratization and globalization as much as on the complex nature of conflicts that affect the security, sovereignty and stability of 21st century nation-states. As formidable as they appear, these threats and challenges may be considered current reiterations of others that mark our histories. In the Atlantic World, nowhere more so than in Latin America, the literature of the military profession has always demonstrated the recognition of lessons of the past applied to problems of the presentation aid in preparation for the future. A principal reason for this is that said literature is in and of itself the product of civil-military collaborations.

  7. Contrasting Effects of Historical Sea Level Rise and Contemporary Ocean Currents on Regional Gene Flow of Rhizophora racemosa in Eastern Atlantic Mangroves.

    Directory of Open Access Journals (Sweden)

    Magdalene N Ngeve

    Full Text Available Mangroves are seafaring taxa through their hydrochorous propagules that have the potential to disperse over long distances. Therefore, investigating their patterns of gene flow provides insights on the processes involved in the spatial genetic structuring of populations. The coastline of Cameroon has a particular geomorphological history and coastal hydrology with complex contemporary patterns of ocean currents, which we hypothesize to have effects on the spatial configuration and composition of present-day mangroves within its spans. A total of 982 trees were sampled from 33 transects (11 sites in 4 estuaries. Using 11 polymorphic SSR markers, we investigated genetic diversity and structure of Rhizophora racemosa, a widespread species in the region. Genetic diversity was low to moderate and genetic differentiation between nearly all population pairs was significant. Bayesian clustering analysis, PCoA, estimates of contemporary migration rates and identification of barriers to gene flow were used and complemented with estimated dispersal trajectories of hourly released virtual propagules, using high-resolution surface current from a mesoscale and tide-resolving ocean simulation. These indicate that the Cameroon Volcanic Line (CVL is not a present-day barrier to gene flow. Rather, the Inter-Bioko-Cameroon (IBC corridor, formed due to sea level rise, allows for connectivity between two mangrove areas that were isolated during glacial times by the CVL. Genetic data and numerical ocean simulations indicated that an oceanic convergence zone near the Cameroon Estuary complex (CEC presents a strong barrier to gene flow, resulting in genetic discontinuities between the mangrove areas on either side. This convergence did not result in higher genetic diversity at the CEC as we had hypothesized. In conclusion, the genetic structure of Rhizophora racemosa is maintained by the contrasting effects of the contemporary oceanic convergence and historical climate

    We present a short review of current theories of glass weathering, including glass dissolution, and hydrolysis of nuclear waste glasses, and leaching of historical glasses from an XAFS perspective. The results of various laboratory leaching experiments at different timescales (30 days to 12 years) are compared with results for historical glasses that were weathered by atmospheric gases and soil waters over 500 to 3000 years. Good agreement is found between laboratory experiments and slowly leached historical glasses, with a strong enrichment of metals at the water/gel interface. Depending on the nature of the transition elements originally dissolved in the melt, increasing elemental distributions are expected to increase with time for a given glass durability context

    Landsberg, H. E.

    It was a pleasure to learn, from a recent (May 4) issue of Eos, of the formation of a permanent Committee on History of Geophysics. There is a dire need for reference material, books, and articles on geophysical history.Let me recommend to them that they take a good look at the Dictionary of the History of Science (W.F. Bynum, E.J. Browne, Roy Porter (Eds.), Princeton University Press, 494 pp., 1981). What follows is not a book review, although it may appear so. It is meant to be a challenge to place geophysics on the map in historical context. In this book, hydrology is dealt with in one sentence under the heading ‘cycle,’ geomagnetism under ‘declination and dip,’ and its history ends with Edward Sabine. Seismology appears under earthquakes. No important seismologist is mentioned. In the biographical index, Wiechert is included only for a contribution to physics. Where are Sir Harold Jeffreys, Galitzin, Gutenberg, Mohorovičić, Lehman, and many others? Meteorology ends with V. Bjerknes and Solberg; Köppen, Richardson, Rossby, and other notables [of] the last century do not seem to exist.

    Full Text Available We comprehend the learning room as a space where teachers and students knowledge cross it other, permeated by the idiosyncrasies from the society that surrounds the school. This study aims know the pedagogical practice of two teachers in the history teaching for the formers years of the fundamental school, to comprehend as the work that they develop interfere in the student’s historical knowledge construction. The study of case method of survey had the contribution of the teachers of two municipal schools from Londrina. The data, collected through the observation inside the learning room and semi structured interviews with the teachers, were analyzed from the theoretical assumptions announced by Isabel Barca, Hilary Cooper and Keity Barton. We concluded that there are similarities and differences on the teacher’s practice and the students behavior in both classrooms. From a general view, the work with the history is based, nearly exclusively, in the didactical book reading and in the demand to the students retain the information from it. There’s a silence in front of the questions raised by the students about the content and the mechanisms that permit the students to comprehend that the past can have many interpretations are inexistent.

  12. The beauty and the beast: reflections about the socio-historical and subcultural context of drag queens and "Tunten" in Berlin.

    Science.gov (United States)

    Balzer, Carsten

    2004-01-01

    In this article, I focus on two different faces found in Berlin's gay subculture: the Tunten and the drag queens. Both are commonly seen as "male homosexual transvestites," although many such individuals today prefer to identify themselves somewhere within a diverse transgender spectrum rather than as transvestites. Tunten and drag queens differ in their gender performativity, their self-image and their chosen role models as well as in the niches in which they have been able to establish themselves in German mainstream society. Based on ethnographic data, I argue against the widespread reductionist view that the differences between Tunten and drag queens lie primarily in style, behavior, talent and success. Nor can these differences be easily explained away as a result of subculture globalization. Instead, I show that there is a simultaneous coexistence of both a subculturally established, "traditional" local transgender culture and a more recently adopted and partly imported, new local transgender culture. The coexistence of these two urban transgender cultures also indicates the paradigm shift in German gay and youth cultures of the last decades. Thus, I will emphasize the importance of the socio-historical and subcultural processes in studying transgender cultures in Western societies.

    Critics of the target article objected to our account of art appreciators' sensitivity to art-historical contexts and functions, the relations among the modes of artistic appreciation, and the weaknesses of aesthetic science. To rebut these objections and justify our program, we argue that the current neglect of sensitivity to art-historical contexts persists as a result of a pervasive aesthetic–artistic confound; we further specify our claim that basic exposure and the design stance are necessary conditions of artistic understanding; and we explain why many experimental studies do not belong to a psycho-historical science of art.

    Conservationists and agriculturists face unprecedented challenges trying to minimize tradeoffs between increasing demands for food, fiber, feed, and biofuels and the resulting loss or reduced values of other ecosystem services, such as those derived from wetlands and biodiversity (Millenium Ecosystem Assessment 2005a, 2005c; Maresch et al. 2008). The Food, Conservation, and Energy Act of 2008 (Pub. L. 110-234, Stat. 923, HR 2419, also known as the 2008 Farm Bill) reauthorized the USDA to provide financial incentives for agricultural producers to reduce environmental impacts via multiple conservation programs. Two prominent programs, the Wetlands Reserve Program (WRP) and the Conservation Reserve Program (CRP), provide incentives for producers to retire environmentally sensitive croplands, minimize erosion, improve water quality, restore wetlands, and provide wildlife habitat (USDA FSA 2008a, 2008b; USDA NRCS 2002). Other conservation programs (e.g., Environmental Quality Incentives Program, Conservation Stewardship Program) provide incentives to implement structural and cultural conservation practices to improve the environmental performance of working agricultural lands. Through its Conservation Effects Assessment Project, USDA is supporting evaluation of the environmental benefits obtained from the public investment in conservation programs and practices to inform decisions on where further investments are warranted (Duriancik et al. 2008; Zinn 1997).

    Full Text Available In South Africa, 2015 was violently ushered out by several ‘must fall’ campaigns, of which the most prominent were the ‘fees’ and ‘Zuma must fall’ campaigns. These ‘must fall’ campaigns conveyed a new sense of urgency by the disgruntled masses towards certain institutions and individuals. Aligning with the ‘must fall’ analogy, the focus of this article is on combatting the notion of misconstrued identities in post-apartheid South Africa. Based on negative generalisation and perceptions of the ‘others’, misconstrued identities prohibit the formation of a collective identity that allows for peaceful co-existence. Consequently, the dynamics of collective identity formation and some of the possibilities for identity formation that reside within the Christian faith are investigated from a practical theological perspective. Given that a practical theological investigation takes both the context and theological reflection as points of departure, it is argued that it can contribute towards the dismantling of misconstrued identities to provide clues for the formation of a positive collective identity for South Africans.

  18. Mind's historicity: its hidden history.

    2013-02-01

    Whereas psychological research can hardly accept the idea of a changing psychological architecture, mind's historicity seems to be commonplace among historians of psychology, at least in recent decades. Attempts to promote a convergence between psychology and history have always existed, though mainly in the margins of both disciplines. Among these attempts, there is a tradition in French psychology that remains quite marginal even to the history of the discipline and is practically unknown out of the French context. Our goal is to introduce this approach, through the work of its main architect, Ignace Meyerson, to an English speaking reader, in the light of current pleas for historicity. Developed within the core of the discipline of psychology, though in dialogue with many others disciplines, Meyerson's historical psychology appears to be more ambitious than other attempts, as it aims at studying psychological activity itself, beyond the history of its conceptualizations. It is concerned not with the analysis of fragmented, isolated, and mechanistic behaviors or cognitive process, but with the study of mind in its functioning through the multiple and changing fields of experience where human beings are involved.

    Full Text Available Assessment and research into this phenomenon of social marginalization and social exclusion of young people at both national and European levels has as a target to find methods of prevention and reduction of this phenomenon and understand the fact that it is only through communication, debates and dialog that will we be able to establish benchmarks for joint action. Young people are one of the age segments which are most affected by the economic recession. It is also accepted that in each of the Member States of the EU, despite different circumstances and levels of economic development, major issues faced by young people are the same: from access to essential services (such as education and health and up to their integration into the labour market with a view to achieving a higher standard of living. The decision makers are constantly interested in solving these stringent problems, which can be found in the policies and strategies for economic recovery and fighting the austerity measures adopted by the Member States of the EU, through a series of programs that have as main objectives combating unemployment and poverty among young people and providing opportunities for more active involvement in their community life: political, social, economic, cultural. In Romania, the problem of young people constitutes an issue of major importance for the Government, which has drawn up for the first time an Integrated Strategy of Romania with regard to young people called "National Strategy for Youth 2014-2020", with particular emphasis on the first role that education must play in this context. Examples of solutions identified by the governors are: an increase in public funding for mentoring programs, for the prevention of school dropout rates, establishment of differentiated educational offers, training schemes designed to eliminate lack of qualification in young people, in such a way as to maintain a competitive and well-prepared generation in the country

    The National Institutes of Health National Heart, Lung, and Blood Institute convened a working group in March 2008 to discuss how therapies for heart failure (HF) might be best advanced using clinical trials involving left ventricular assist devices (LVAD). This group opined that the field was ready for a trial to assess the use of long-term ventricular assist device therapy in patients who are less ill than patients currently eligible for destination therapy, which resulted in the Randomized Evaluation of VAD InterVEntion before Inotropic Therapy (REVIVE-IT) pilot study. The specific objective of REVIVE-IT was to compare LVAD therapy with optimal medical management in patients with less advanced HF than current LVAD indications to determine if wider application of permanent LVAD use to less ill patients would be associated with improved survival, quality of life, or functional capacity. REVIVE-IT represented an extraordinary effort to provide data from a randomized clinical trial to inform clinicians, scientists, industry, and regulatory agencies about the efficacy and safety of LVAD therapy in a population with less advanced HF. Despite significant support from the medical community, industry, and governmental agencies, REVIVE-IT failed to accomplish its goal. The reasons for its failure are instructive, and the lessons learned from the REVIVE-IT experience are likely to be relevant to any future study of LVAD therapy in a population with less advanced HF.

  2. VOX POPULI? VOX HUMBUG! – RISING TENSION BETWEEN THE SOUTH AFRICAN EXECUTIVE AND JUDICIARY CONSIDERED IN HISTORICAL CONTEXT – PART ONE

    Directory of Open Access Journals (Sweden)

    David Hulme

    2012-12-01

    Full Text Available This article takes as its starting point a controversy which has arisen around a proposed assessment by the South African government of the decisions of the Constitutional Court, giving rise to concerns that this will constitute undue interference with the independence of the judiciary. Part One of this article traces and analyses the developing controversy. It then compares the current clash between the South African Executive and Judiciary to a similar clash which took place in seventeenth century England, between King James I and Chief Justice Edward Coke. Such clashes appear to be fairly common, particularly in young democracies in which democratic institutions are yet to be properly consolidated. Although not immediately apparent, the similarities between the situation which existed in seventeenth England at the time of James I and that in present-day South Africa are instructive. In tracing the development of these two clashes between the executive and judiciary, Part One of this article lays the foundation for a more in-depth comparison in Part Two.

  3. Assessing historical empathy through simulation – How do Finnish teacher students achieve contextual historical empathy?

    Full Text Available There has been a great deal of international debate about introducing historical empathy as the focus in teaching history. However, as it is, the contents of the concept have been included in the curricula in many countries. Nevertheless, practising stepping into the shoes of a person from a previous era is still in its infancy in schools in many locations – Finland included. This article discusses Finnish class teacher students' understanding of historical empathy. The article is based on a study where 360 class teacher students played a game simulating the Cuban Missile Crisis. Their task was to assume the roles of the superpower leaders and make decisions on the basis of these roles. The simulation showed that a majority of the student teachers are able to attain a level of contextual historical empathy. They were able to empathize with the historical context in question and make such decisions that would have been possible for the historical actors. Some of the playing groups on the other hand, referred to their current knowledge and attitudes, which, according to Ashby and Lee's empathy classification, shows lower-level empathy. The study corroborates previous research results concerning great discrepancies in the understanding of empathy prevalent within one age group. Moreover, the study raises the question of how historical empathy should be handled in teaching if many future teachers have difficulties in understanding it.

    Flow in and around coral reefs affects a number of physical, chemical and biologic processes that influence the health and sustainability of coral reef ecosystems. These range from the residence time of sediment and contaminants to nutrient uptake and larval retention and dispersal. As currents approach a coast they diverge to flow around reef structures, causing high horizontal and vertical shear. This can result in either the rapid advection of material in localized jets, or the retention of material in eddies that form in the lee of bathymetric features. The high complexity and diversity both within and between reefs, in conjunction with past technical restrictions, has limited our understanding of the nature of flow and the resulting flux of physical, chemical, and biologic material in these fragile ecosystems. Sediment, nutrients, and other pollutants from a variety of land-based activities adversely impact many coral reef ecosystems in the U.S. and around the world. These pollutants are transported in surface water runoff, groundwater seepage, and atmospheric fallout into coastal waters, and there is compelling evidence that the sources have increased globally as a result of human-induced changes to watersheds. In Guam, and elsewhere on U.S. high islands in the Pacific and Caribbean, significant changes in the drainage basins due to agriculture, feral grazing, fires, and urbanization have in turn altered the character and volume of land-based pollution released to coral reefs. Terrigenous sediment run-off (and the associated nutrients and contaminants often absorbed to it) and deposition on coral reefs are recognized to potentially have significant impact on coral health by blocking light and inhibiting photosynthesis, directly smothering and abrading coral, and triggering increases in macro algae. Studies that combine information on watershed, surface water- and groundwater-flow, transport and fate of sediment and other pollutants in the reef environment

  7. Historical context of the Albanian Constitutional Court

    Full Text Available The Albanian legal tradition is based mostly on the traditional and customary laws. The Ottoman Empire ruled Albania for nearly five centuries and applied some of its translation of Sharia law together with its own rules and procedures. However, the Albanian population, especially in the north was governed by its own customary laws that were included in the Kanun of Lek Dukagjini. For a long period of time, these customary laws were unwritten and were learned generation aft er generation. The Kanun of Lek Dukagjini had very few rules and procedures regarding penal law. They were not arranged properly and there were some repetition for different cases. The National Court was implemented by a popular gathering of the oldest man of the village called Pleqnia. It used to decide on issues immediately, and there was no review of their issues. The rules were clear, simple and strict. There are some ideas from different Albanian researchers that the communist system although exported as an idea from abroad, based its laws and rules very much on the Albanian tradition as for example the creation also People’s Court. There was no institution of judicial review. These researchers point out that it was for this reason that the communist system in Albania lasted for nearly fifty years.

    Full Text Available This paper aims to show some contributions of historical critical pedagogy to Geography teaching. Such thoughts aim to discuss how this teaching enters school education in the context of neoliberalism. Assuming that the emptiness in Geography teaching in school education is a result of Brazilian educational policies in neoliberalism, we intend to characterize the impairment of the critical perspective on this area of knowledge and present some contributions of historical critical pedagogy to face and overcome the current order. Besides, we seek to highlight the required knowledge to achieve an education that contributes to build a different society.

    King, Jackie; McFarlane, Gordon A; Gertseva, Vladlena; Gasper, Jason; Matson, Sean; Tribuzio, Cindy A

    For over 100 years, sharks have been encountered, as either directed catch or incidental catch, in commercial fisheries throughout the Northeast Pacific Ocean. A long-standing directed fishery for North Pacific Spiny Dogfish (Squalus suckleyi) has occurred and dominated shark landings and discards. Other fisheries, mainly for shark livers, have historically targeted species including Bluntnose Sixgill Shark (Hexanchus griseus) and Tope Shark (Galeorhinus galeus). While incidental catches of numerous species have occurred historically, only recently have these encounters been reliably enumerated in commercial and recreational fisheries. In this chapter we present shark catch statistics (directed and incidental) for commercial and recreational fisheries from Canadian waters (off British Columbia), southern US waters (off California, Oregon, and Washington), and northern US waters (off Alaska). In total, 17 species of sharks have collectively been encountered in these waters. Fishery encounters present conservation challenges for shark management, namely, the need for accurate catch statistics, stock delineation, life history parameter estimates, and improved assessments methods for population status and trends. Improvements in management and conservation of shark populations will only come with the further development of sound science-based fishery management practices for both targeted and incidental shark fisheries. © 2017 Elsevier Ltd All rights reserved.

  13. Physiologically based pharmacokinetic modeling of human exposure to perfluorooctanoic acid suggests historical non drinking-water exposures are important for predicting current serum concentrations.

    2017-09-01

    Manufacturing of perfluorooctanoic acid (PFOA), a synthetic chemical with a long half-life in humans, peaked between 1970 and 2002, and has since diminished. In the United States, PFOA is detected in the blood of >99% of people tested, but serum concentrations have decreased since 1999. Much is known about exposure to PFOA in drinking water; however, the impact of non-drinking water PFOA exposure on serum PFOA concentrations is not well characterized. The objective of this research is to apply physiologically based pharmacokinetic (PBPK) modeling and Monte Carlo analysis to evaluate the impact of historic non-drinking water PFOA exposure on serum PFOA concentrations. In vitro to in vivo extrapolation was utilized to inform descriptions of PFOA transport in the kidney. Monte Carlo simulations were incorporated to evaluate factors that account for the large inter-individual variability of serum PFOA concentrations measured in individuals from North Alabama in 2010 and 2016, and the Mid-Ohio River Valley between 2005 and 2008. Predicted serum PFOA concentrations were within two-fold of experimental data. With incorporation of Monte Carlo simulations, the model successfully tracked the large variability of serum PFOA concentrations measured in populations from the Mid-Ohio River Valley. Simulation of exposure in a population of 45 adults from North Alabama successfully predicted 98% of individual serum PFOA concentrations measured in 2010 and 2016, respectively, when non-drinking water ingestion of PFOA exposure was included. Variation in serum PFOA concentrations may be due to inter-individual variability in the disposition of PFOA and potentially elevated historical non-drinking water exposures.

    Lee Irwin

    2017-10-01

    Full Text Available American theories of reincarnation have a long and complex history, dating from 1680s to the present. It is the purpose of this paper to highlight the main currents of reincarnation theory in the American context, giving a brief historical survey. Sources surveyed begin with Native American traditions, and then move to immigrant traditions based in Western Esotericism, Christianity, Judaism, missionary Hinduism and Buddhism, Spiritualism, Theosophy, Rosicrucianism, and concludes with more current theoretical influences, based in paranormal science research. The paper demonstrates that current theories of reincarnation are increasingly less dependent upon religious support and increasingly based in direct personal experience, paranormal research, and new therapeutic models. The paper concludes with some reflections on the complexity of reincarnation theory and raises questions concerning the future development of such theory.

  15. Historical centres: changing definitions

    Directory of Open Access Journals (Sweden)

    Roberta Lazzarotti

    2014-02-01

    Full Text Available Since the end of the Second World War, the architectural and planning culture has been showing a fluctuating attention to the theme of historical centres and their enhancement. First of all this uneven progress explains the difficulty to reach a homogeneous definition and this is still lacking. During a long phase of this period, the historical parts of the town were considered as objects to be preserved in an integral way, as urban monuments. This is mostly due to the high symbolic value of these settlements, that represent fundamental landmarks. Identity building and empowerment of local communities are indispensable conditions for any development programme, especially in the case of centres or other historic environments at risk of abandonment. The progressive evolution of this concept brings awareness of the impossibility of separating – either in analytical or in planning terms ­ historical centres from their urban and territorial contexts, which are linked by mutual, deep relationships. This article attempts to retrace the steps signaled by the publication of international documents and conventions, from the Charter of Gubbio (1960 to the Charter of Krakow and the European Landscape Convention (2000; they obviously represent particular points of view, not exhaustive of the richness of the positions in the debate, but extremely significant in terms of diffusion and consensus.

    Hunger knows no boundaries or borders. While much research has focused on undernutrition on a national scale, this report evaluates it at subnational levels for Sub-Saharan Africa (SSA) to pinpoint hotspots where the greatest challenges exist. Undernutrition is assessed with a spatial resolution of 30 arc-minutes by investigating anthropometric data on weight and length of individuals. The impact of climate change on production of six major crops (cassava, maize, wheat, sorghum, rice and millet) is analyzed with a GIS-based Environmental Policy Integrated Climate (GEPIC) model with the same spatial resolution. Future hotspots of hunger are projected in the context of the anticipated climate, social, economic, and bio-physical changes. The results show that some regions in northern and southwestern Nigeria, Sudan and Angola with a currently high number of people with undernutrition might be able to improve their food security situation mainly through increasing purchasing power. In the near future, regions located in Ethiopia, Uganda, Rwanda and Burundi, southwestern Niger, and Madagascar are likely to remain hotspots of food insecurity, while regions located in Tanzania, Mozambique and the Democratic Republic of Congo might face more serious undernutrition. It is likely that both the groups of regions will suffer from lower capacity of importing food as well as lower per capita calorie availability, while the latter group will probably have sharper reduction in per capita calorie availability. Special attention must be paid to the hotspot areas in order to meet the hunger alleviation goals in SSA.

  17. Programming maternal and child overweight and obesity in the context of undernutrition: current evidence and key considerations for low- and middle-income countries.

    Jaacks, Lindsay M; Kavle, Justine; Perry, Abigail; Nyaku, Albertha

    2017-05-01

    The goals of the present targeted review on maternal and child overweight and obesity were to: (i) understand the current situation in low- and middle-income countries (LMIC) with regard to recent trends and context-specific risk factors; and (ii) building off this, identify entry points for leveraging existing undernutrition programmes to address overweight and obesity in LMIC. Trends reveal that overweight and obesity are a growing problem among women and children in LMIC; as in Ghana, Kenya, Niger, Sierra Leone, Tanzania and Zimbabwe, where the prevalence among urban women is approaching 50 %. Four promising entry points were identified: (i) the integration of overweight and obesity into national nutrition plans; (ii) food systems (integration of food and beverage marketing regulations into existing polices on the marketing of breast-milk substitutes and adoption of policies to promote healthy diets); (iii) education systems (integration of nutrition into school curricula with provision of high-quality foods through school feeding programmes); and (iv) health systems (counselling and social and behaviour change communication to improve maternal diet, appropriate gestational weight gain, and optimal infant and young child feeding practices). We conclude by presenting a step-by-step guide for programme officers and policy makers in LMIC with actionable objectives to address overweight and obesity.

    Marco D'Arienzo

    2013-03-01

    Full Text Available 90Y is traditionally considered as a pure β– emitter. However, the decay of this radionuclide has a minor branch to the 0+ first excited state of 90Zr at 1.76 MeV, that is followed by a β+/β– emission. This internal pair production has been largely studied in the past because it is generated by a rare electric monopole transition (E0 between the states 0+/0+ of 90Zr. The positronic emission has been recently exploited for nuclear medicine applications, i.e. positron emission tomography (PET acquisitions of 90Y-labelled radiopharmaceuticals, widely used as therapeutic agents in internal radiation therapy. To date, this topic is gaining increasing interest in the radiation dosimetry community, as the possibility of detecting β+ emissions from 90Y by PET scanners may pave the way for an accurate patient-specific dosimetry. This could lead to an explosion in scientific production in this field. In the present paper the historical background behind the study of the internal pair production of the 0+/0+ transition of 90Zr is presented along with most up to date measured branch ratio values. An overview of most recent studies that exploit β+ particles emitted from 90Y for PET acquisitions is also provided.

    Full Text Available Paul Ricoeur is passionate for life and society. This is not a matter of discussion, since one knows his trajectory, his fights and achievements which reflect wonderful multicolor prisms in his works. We can say that he is, and not that he was, because his essays of narrating the time that is today, the time of the narrative which is brought to our present perspective each moment while one narrates something, indicate a Ricoeur that is revived at different and new moments in which the reader exposes himself or herself in his presence, by narrating.In Time and Narrative 3, based on his passion, one can find a text that inquires about the manner in which we have faced, as a society, our past and in which we expect to construct our future. In Towards a Hermeneutics of Historical Consciousness, Ricoeur presents a problem that reveals how humans are becoming something different than themselves while they “preterify” the past and leave the present without a tradition; it means that such a thought is equivalent to an absence of expectations and hopes about the future. This is the discussion of the text that follows.

    The model marine broadcast-spawner barnacle Chthamalus montagui was investigated to understand its genetic structure and quantify levels of population divergence, and to make inference on historical demography in terms of time of divergence and changes in population size. We collected specimens from rocky shores of the north-east Atlantic Ocean (4 locations), Mediterranean Sea (8) and Black Sea (1). The 312 sequences 537 bp) of the mitochondrial cytochrome c oxidase I allowed to detect 130 haplotypes. High within-location genetic variability was recorded, with haplotype diversity ranging between h = 0.750 and 0.967. Parameters of genetic divergence, haplotype network and Bayesian assignment analysis were consistent in rejecting the hypothesis of panmixia. C. montagui is genetically structured in three geographically discrete populations, which corresponded to north-eastern Atlantic Ocean, western-central Mediterranean Sea, and Aegean Sea-Black Sea. These populations are separated by two main effective barriers to gene flow located at the Almeria-Oran Front and in correspondence of the Cyclades Islands. According to the 'isolation with migration' model, adjacent population pairs diverged during the early to middle Pleistocene transition, a period in which geological events provoked significant changes in the structure and composition of palaeocommunities. Mismatch distributions, neutrality tests and Bayesian skyline plots showed past population expansions, which started approximately in the Mindel-Riss interglacial, in which ecological conditions were favourable for temperate species and calcium-uptaking marine organisms.

    Full Text Available The POD Parser is Python software for parsing the OCR’d (optical character recognised text of digitised historical Scottish Post Office Directories (PODs to produce a consistent structured format for the data and for geocoding each address. The software was developed as part of the AddressingHistory project which sought to combine digitised historic directories with digitised and georeferenced historic maps.  The software has potential for reuse in multiple research contexts where historical post office directory data is relevant, and is therefore particularly of use in historical research into social, economic or demographic trends. The POD Parser is currently designed for use with Scottish directories but is extensible, perhaps with some adaptation, to use with other similarly formatted materials such as the English Trade Directories.

    2016-12-01

    Classroom teachers face many challenges today such as new standards, the moving targets of high stakes tests and teacher evaluations, inconsistent/insufficient access to resources and evolving education policies. Science education in the K-5 context is even more complex. NGSS can be intimidating, especially to K-5 educators with little science background. High stakes science tests are slow to catch up with newly drafted state level science standards, leaving teachers unsure about what to change and when to implement updated standards. Amid all this change, many schools are also piloting new technology programs. Though exciting, tech initiatives can also be overwhelming to teachers who are already overburdened. A practical way to support teachers in science while remaining mindful of these stressors is to design and share resources that leverage other K-5 school initiatives. This is often done by integrating writing or math into science learning to meet Common Core requirements. This presentation will suggest a method for bringing Earth and space science learning into elementary / early childhood classrooms by utilizing the current push for tablet technology. The goal is to make science integration reasonable by linking it to technology programs that are in their early stages. The roles and uses of K-5 Earth and space science apps will be examined in this presentation. These apps will be linked to NGSS standards as well as to the science and engineering practices. To complement the app resources, two support frameworks will also be shared. They are designed to help educators consider new technologies in the context of their own classrooms and lessons. The SAMR Model (Puentadura, 2012) is a conceptual framework that helps teachers think critically about the means and purposes of integrating technology into existing lessons. A practical framework created by the author will also be shared. It is designed to help teachers identify and address the important logistical

    In late 1915, Albert Einstein (1879-1955) completed as series of papers on a generalized theory of gravitation that were to constitute a major conceptual change in the history of modern physics and the crowning achievement of his scientific career. But this accomplishment came after a decade of intense intellectual struggle and was received with muted enthusiasm. Einstein's previously unpublished writings and massive correspondence, edited by the Einstein Papers Project, provide vivid insights into the historical, personal, and scientific context of the formulation, completion, and reception of GR during the first decades of the 20th century.

    In 2013, the NSF's Ocean Observatories Initiative (OOI) will deploy 22 instrument suites within the caldera of Axial Seamount as part of the cabled observatory component implemented by the Regional Scale Nodes (RSN) at the University of Washington. The cabled infrastructure will initially provide Axial caldera with a total of 8kW of power and 11Gbps of data bandwidth. Only an approximate 20% fraction will be used by "core instrumentation"-instrumentation supported and maintained by OOI-RSN. Thus, the OOI provided infrastructure is highly, and readily, expandable to include community-generated instrumention once the system is commissioned and begins operations in early 2015. Here we present the details of the current design of the cabled observatory at Axial Seamount, including locations of instruments, data products, and sampling rates placed in the context of meter scale resolution bathymetry and down-looking photomosaics of the experimental sites. The April 2011 Axial eruption is a demonstration of the importance of transmitting seismic, video, and vent fluid chemistry information in real-time. The eruptive event, or series of events, in April 2011 went undetected until a series of ROV/AUV cruises, planned separately and years in advance, made observations to discover, confirm, and detail the transformation to Axial (see Chadwick et al., this session). What transpired during, and shortly after, the eruption will remain largely unknown, as the initial extraordinary fluxes of heat, chemistry and biology will have decayed in the intervening three and a half months. Here we detail the response capabilities of the OOI-RSN cabled observatory to a future eruptive event under two scenarios-as built, and an expanded version using existing technology.

  11. Certification of forests and wood products in Serbia in the context of new European union legislations: Current situation, problems and challenges

    Full Text Available The paper presents research results of the current situation in the area of certification of forests and wood products in Serbia in the context of new European Union legislation referring to the placement of wood and wood products on this market. The objective of the research was to observe the situation, phases which Serbia implemented in the process of forest and wood products certification until now, as well as the problems and challenges the companies in this process face. Based on research results, future development of the market of certified wood products in Serbia was assessed and the proposal of measures which should be realized in order for Serbia to become a country whose companies will be ready for the moment when provisions and measures of the new EU legislation become effective was given. The selection of the abovementioned objective was conditioned by the fact that from January 1st, 2013 new legislation takes effect, with significantly stricter terms for the placement of wood and wood products from other countries on this market. One of the conditions which will have to be fulfilled by the companies wishing to export their products on this market refers to proving their origin. Since the EU is the most significant market for wood products exported from Serbia, fulfillment of the stated and other terms from the new EU legislation is of great importance to Serbian companies. Until the beginning of September 2010, only 387,000 ha were certified, namely 17.2% of the total area under forests. In the same period, only 33 wood processing companies in Serbia possessed CoC certificates for their products. Such a small number of companies possessing certificates for their wood products compared to competitive neighboring countries can represent a serious limitation in achieving their satisfactory competitiveness on the EU market in the following period.

  12. Anomalies and contradictions in an airport construction project: a historical analysis based on Cultural-Historical Activity Theory.

    Large construction projects involve the functioning of a complex activity system (AS) in network format. Anomalies such as accidents, delays, reworks, etc., can be explained by contradictions that emerge historically in the system. The aim of this study was to analyze the history of an airport construction project to understand the current contradictions and anomalies in the AS and how they emerged. A case study was conducted for this purpose, combining Collective Work Analysis, interviews, observations, and analysis of documents that provided the basis for sessions in the Change Laboratory, where a participant timeline was elaborated with the principal events during the construction project. Based on the timeline, a historical analysis of the airport's AS revealed critical historical events and contradictions that explained the anomalies that occurred during the project. The analysis showed that the airport had been planned for construction with politically determined deadlines that were insufficient and inconsistent with the project's complexity. The choice of the contract modality, which assigned responsibility to a joint venture for all of the project's phases, was another critical historical event, because it allowed launching the construction before a definitive executive project had been drafted. There were also different cultures in companies working together for the first time in the context of a project with time pressures and outsourcing of activities without the necessary coordination. Identifying these contradictions and their historical origins proved essential for understanding the current situation and efforts to prevent similar situations in the future.

  13. Current levels and composition profiles of PBDEs and alternative flame retardants in surface sediments from the Pearl River Delta, southern China: Comparison with historical data

    Polybrominated diphenyl ethers (PBDEs) and alternative flame retardants were measured in surface sediments collected during 2009–2010 from the Pearl River Delta, southern China (a large manufacturing base for electronics/electrical products), to evaluate the influence of China's RoHS directive (adopted in 2006) on their environmental occurrence. The concentrations in sediments from different water systems ranged from 3.67 to 2520 ng/g (average of 17.1–588 ng/g) for PBDEs and from 0.22 to 5270 ng/g (average of 11.3–454 ng/g) for the alternative retardants. Although the PBDE levels have decreased significantly compared with those in sediments collected in 2002 in this region, the levels of alternative decabromodiphenyl ethane (DBDPE) have exceeded those of BDE209 (two predominant halogenated flame retardants (HFRs) in China) in the majority of sediments. This finding suggests a different contaminant pattern of HFRs in current sediments due to the replacement of the deca-BDE mixture with DBDPE in this region. In addition, sediment concentrations of discontinued PBDEs in the rural area are clearly elevated due to e-waste dismantling. The congener profiles of PBDEs in the current sediments (with more abundant lower-brominated congeners) differed substantially from those in 2002 and from the technical products, suggesting that biological or photolytic debromination of PBDEs may have occurred in the environment. - Highlights: ► PBDE levels in sediments have decreased substantially since China's RoHS directive. ► Contamination of novel DBDPE has exceeded that of deca-BDE in the PRD sediments. ► The congener profiles of PBDEs in the sediments have changed significantly. ► Significant biological or photolytic degradation of PBDEs may occur in the environment

    The objective of the study was to investigate how exposure to carbon disulfide (CS2) in a rayon-manufacturing plant has changed within two decades and whether it is possible to calculate valid data for the individual cumulative exposure. The data for CS2 concentration in air and biological exposure monitoring (2-thio-1,3-thiaxolidine-4-carboxylic acid (TTCA) in urine) from two cross-sectional studies, performed in 1992 (n = 362) and 2009 (n = 212) in a German rayon-manufacturing plant, were compared to data obtained from company-internal measurements between the studies. Using the data from the cross-sectional studies and company-internal data, cumulative external exposure and the cumulative internal exposure were calculated for each worker. External and internal CS2 exposure of the employees decreased from 1992 (medians 4.0 ppm and 1.63 mgTTCA/g creatinine) to 2009 (medians 2.5 ppm and 0.86 mg/g). However, company-internal CS2 data do not show a straight trend for this period. The annual medians of the company-internal measurement of external exposure to CS2 have varied between 2.7 and 8.4 ppm, in which median values exceeded 5 ppm generally since 2000. The annual medians for the company-internal biomonitoring assessment ranged between 1.2 and 2.8 mg/g creatinine. The cumulative CS2 exposure ranged from 8.5 to 869.5 ppm years for external exposure and between 1.30 and 176.2 mg/g creatinine years for the internal exposure. Significant correlations were found between the current air pollution and the internal exposure in 2009 but also between the cumulative external and internal CS2 exposure. Current exposure data, usually collected in cross-sectional studies, rarely allow a reliable statement on the cumulative dose, because of higher exposure in the past and of fluctuating courses of exposure. On the other hand, company-internal exposure data may be affected by non-representative measurement strategies. Some verification of the reliability of

    The organizations and machines engaged in a severe nuclear crisis would be its tangible and partially quantifiable factors. For that reason they often dominate our thinking about superpower confrontations. Military organizations, however, are not automatons that can run amok on their own. The perceptions of leaders and populations propel the course of events, and their mindsets are shaped by what experience, history, and myth claim to say about war. Since there has never been combat between nuclear-armed states, it is debatable whether the past has any relevance to what we now face. But the part is all we have to go on. Thus soldiers and statesmen are still haunted by the manner in which this century's two great wars began, and the past thereby influences the thoughts that lead to weapons, to military plans, and to decisions that could turn peace into war. It is therefore essential to have some appreciation for the historical roots that nourish our expectations about international conflict. This paper describes some of these roots

  19. Historical perspective

    1982-01-01

    A historical perspective of the nuclear waste issue is presented, beginning from the Atoms for Peace Legislation which made nuclear technology available to private industry in 1953 to 1954. Once the nuclear process had been demonstrated to be a technically and economically feasible method to convert thermal energy for electric power generation, commercial application began. The issue of nuclear waste management did not keep up with higher priorities. As early as 1957, research into storing the waste in geological structures was conducted by the National Academy of Sciences, and considerable technical progress was made in the 60's. During the 60's and 70's, numerous legislative actions (e.g., Clean Air Act, Clean Water Act, Environmental Policy Act) had a significant impact on nuclear waste dipsosal decisions. In 1971 to 1972 the Atomic Energy Commission authorized a nuclear waste repository in Kansas, a decision which was amended the following year and finally abandoned altogether in 1974. The OPEC oil embargo and ensuing price actions moved nuclear power into a more prominent position in the United States' plans for energy independence. This increased the stress between environmental concerns and economic need. The Carter Administration indefinitely deferred reprocessing of spent fuel and initiated a government-wide review of nuclear policy issues. The Congress did not actively begin to fashion a nuclear waste program until February 1980. The legislation which passed the Senate in the Spring of '82, and a compromise version pending before the House, may resolve the issue by establishing a long-term stable policy which will contain milestones, goals and specific decision making processes; it will include a mechanism for the public and the states to be involved; and it will insure adequate financing provisions

    2007-01-01

    The appearance of an adrenocorticotropic hormone (ACTH)-producing tumor after bilateral adrenalectomy for Cushing disease was first described by Nelson in 1958. The syndrome that now bears his name was characterized by hyperpigmentation, a sellar mass, and increased plasma ACTH levels. The treatment of Cushing disease has changed drastically since the 1950s, when the choice was adrenalectomy. Thus, the occurrence, diagnosis, and treatment of Nelson syndrome have changed as well. In the modern era of high-resolution neuroimaging, transsphenoidal microneurosurgery, and stereotactic radiosurgery, Nelson syndrome has become a rare entity. The authors describe the history of the diagnosis and treatment of Nelson syndrome. In light of the changes described, the authors believe this disease must be reevaluated in the contemporary era and a modern paradigm adopted.

    2014-06-01

    Recent years have seen the rise of historical trauma as a construct to describe the impact of colonization, cultural suppression, and historical oppression of Indigenous peoples in North America (e.g., Native Americans in the United States, Aboriginal peoples in Canada). The discourses of psychiatry and psychology contribute to the conflation of disparate forms of violence by emphasizing presumptively universal aspects of trauma response. Many proponents of this construct have made explicit analogies to the Holocaust as a way to understand the transgenerational effects of genocide. However, the social, cultural, and psychological contexts of the Holocaust and of post-colonial Indigenous "survivance" differ in many striking ways. Indeed, the comparison suggests that the persistent suffering of Indigenous peoples in the Americas reflects not so much past trauma as ongoing structural violence. The comparative study of genocide and other forms of massive, organized violence can do much to illuminate both common mechanisms and distinctive features, and trace the looping effects from political processes to individual experience and back again. The ethics and pragmatics of individual and collective healing, restitution, resilience, and recovery can be understood in terms of the self-vindicating loops between politics, structural violence, public discourse, and embodied experience. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Recently increasing evidence has been provided pointing to a close relation of salt consumption to hypertension as well as to target organ damage. It is interesting to note that the discussion concerning salt is unusually emotional. This may be explained, at least in part, by the fact that since ancient times salt had deep symbolic significance, as exemplified, mostly subconsciously, by many customs and expressions still in current use. In the past salt was essential to preserve food. The past importance of salt as a commodity can well be compared with that of oil today. These and further historical aspects of the role of salt are briefly dealt with in this article.

    2017-05-01

    In 2003, nuclear power received renewed interest as a perceived climate-neutral way to meet high energy demands of large industrialized countries, such as China, India, Russia and the USA. It triggered a growing demand for uranium (U) as nuclear fuel. Dubbed the 'nuclear renaissance', the U-price rose over tenfold before the global credit crisis dampend the rush. Many efforts to capitalise on the renewed demand focused on Africa. This paper provides an overview on the type and extent of uranium mining, production and exploration on the African continent and discusses the economic benefits as well as the potential environmental and health risks and the long-term needs for remediation of legacy sites. The actual historical results of uranium mining activities in more than thirty African countries provide data against which to assess the existing risks of uranium development. The already existing uraniferous waste in several African countries threatens scarce water resources and the health of adjacent residents. Responsibility should rest with the governments and the companies to ensure that these threats are not realized.

    As part of a community/university collaborative effort to promote the mental health and well-being of Diné (Navajo) youth, we explored the relevance of addressing historical trauma and current structural stressors, and of building on individual and community strengths through healing and social transformation at multiple levels. Qualitative analyses of 74 ethnographic interviews with 37 Diné youth, parents, and grandparents suggested that a focus on historical trauma as a conceptual frame for behavioral health inequities, understood within the context of resilience and survival, is appropriate. Our findings also highlight the salience of current stressors such as poverty and violence exposure. We explore the fit of an historical trauma healing framework and present implications for intervention and transformation through revitalization of traditional knowledge, culturally based healing practices, intergenerational education, and social change strategies designed to eliminate social inequities.

    The U.S. Geological Survey (USGS) Pacific Coastal and Marine Science Center (PCMSC) initiated an investigation in the National Park Service’s (NPS) War in the Pacific National Historical Park (WAPA) to provide baseline scientific information on coastal circulation and water-column properties along west-central Guam, focusing on WAPA’s Agat Unit, as it relates to the transport and settlement of coral larvae, fish, and other marine organisms. The oceanographic data and numerical circulation modeling results from this study demonstrate that circulation in Agat Bay was strongly driven by winds and waves at longer (>1 day) timescales and by the tides at shorter (Turbidity was relatively low in Agat Bay and was similar to levels measured elsewhere along west-central Guam. The numerical circulation modeling results provide insight into the potential paths of buoyant material released from a series of locations along west-central Guam under summer non-trade wind forcing conditions that characterize coral spawning events. This information may be useful in evaluating the potential zones of influence/impact resulting from transport by surface currents of material released from these select locations.

  13. Historical ecology: past, present and future.

    2015-11-01

    The term 'historical ecology' has been used with various meanings since the first half of the 20th century. Studies labelled as historical ecology have been produced in at least four academic disciplines: history, ecology, geography and anthropology. Although all those involved seem to agree that historical ecology concerns the historical interconnectedness of nature and human culture, this field of study has no unified methodology, specialized institutional background and common publication forums. Knowledge of the development of historical ecology is also limited. As a result, the current multitude of definitions of historical ecology is accompanied by divergent opinions as to where the origins of the field are to be sought. In this review, I follow the development of historical ecology from the 18th century to the present. In the first part, I briefly describe some early examples of historical ecological investigations, followed by a description of the various scientific strands in the 20th century that contributed to the formation of historical ecology. In the second part, I discuss the past five decades of historical ecological investigations in more detail, focusing mostly (but not exclusively) on works that their respective authors identified as historical ecology. I also examine the appearance and interconnectedness of the two main trends (ecological and anthropological) in historical ecological research. In the last part, I attempt to outline the future of historical ecology based on common features in existing research. It appears that at present historical ecology is at a crossroads. With rapidly growing interest in historical ecological research, it may move towards institutionalization or remain an umbrella term. © 2014 The Authors.

    Full Text Available This paper discusses two Serbian science-fiction stories with a special emphasis on the motives in their narrative structure; the motive analysis is focused on those motives that represent a transposition of 'historical tradition' elements. The key words connecting images appearing in this context are: fear of losing (national identity and a strategy of resistance towards those, who presumably, want to 'take over' the identity. In this sense, a return to 'the historical tradition', in the analyzed texts, aims to reassess certain past models indicating at the same time those that have successfully served and endured as historical models in this discourse.

    Full Text Available State leadership in Russia is determined by historical and cultural as well as by legal and institutional premises. The analysis of ways of obtaining legitimacy by state leaders of the Russian Federation is a borderline issue of political science, sociology, and history. The conditions that favor the creation of the archetype on the Russian ground are undoubtedly: extremely centralized political power in Russia (one central decision-making center whose decisions were arbitrarily arbitrary, the problem of the enforcement of the rules of the trilateral division of power (the legislative sphere dominated the legislature, the low level of control Social rulers (lack of effective legal mechanisms to verify the effects of their activities, paternalism of the leadership system and low participation of representative institutions in public life. The aim of the article is to situate in the field of considerations about the archetype of Russian power the concept of Yuri Pivovarov, according to which not only civilization baggage and the immaturity of civil society have decided the legitimacy of the state leadership of the Russian Federation. According to him, the problem of the participation of the political elite in the redistribution of goods (and the low level of participation of citizens in the process of ownership separation is of significant importance. According to the theory of the Russian political scientist, the basis for understanding the phenomenon of Russian state leadership is the combination of elements of archetypal leadership with a proper interpretation of the relation of freedom – property.

  19. A case study of secondary teachers facilitating a historical problem-based learning instructional unit

    Science.gov (United States)

    Pecore, John L.

    Current curriculum trends promote inquiry-based student-centered strategies as a way to foster critical thinking and learning. Problem-based learning (PBL), a type of inquiry focusing on an issue or "problem," is an instructional approach taught on the basis that science reform efforts increase scientific literacy. PBL is a constructivist approach to learning real life problems where understanding is a function of content, context, experiences, and learner goals; historical PBL situates the lesson in a historical context and provides opportunities for teaching NOS concepts. While much research exists on the benefits of historical PBL to student learning in general, more research is warranted on how teachers implement PBL in the secondary science curriculum. The purpose of this study was to examine the classroom-learning environment of four science teachers implementing a historical PBL instructional unit to identify the teachers' understandings, successes and obstacles. By identifying teachers' possible achievements and barriers with implementing a constructivist philosophy when executing historical PBL, educators and curriculum designers may improve alignment of the learning environment to constructivist principles. A qualitative interpretive case study guided this research study. The four participants of this study were purposefully and conveniently selected from biology teachers with at least three years of teaching experience, degrees in education, State Licensure, and completion of a PBL workshop. Data collection consisted of pre and post questionnaires, structured interviews, a card sort activity in which participants categorized instructional outcomes, and participant observations. Results indicated that the four teachers assimilated reform-based constructivist practices to fit within their preexisting routines and highlighted the importance of incorporating teachers' current systems into reform-based teacher instruction. While participating teachers

    Full Text Available This paper attempts to review and reconsider the role of context in mobile learning and starts by outlining definitions of context-aware mobile learning as the technologies have become more mature, more robust and more widely available and as the notion of context has become progressively richer. The future role of context-aware mobile learning is considered within the context of the future of mobile learning as it moves from the challenges and opportunities of pedagogy and technology to the challenges and opportunities of policy, scale, sustainability, equity and engagement with augmented reality, «blended learning», «learner devices», «user-generated contexts» and the «internet of things». This is essentially a perspective on mobile learning, and other forms of technology-enhanced learning (TEL, where educators and their institutions set the agenda and manage change. There are, however, other perspectives on context. The increasing availability and use of smart-phones and other personal mobile devices with similar powerful functionality means that the experience of context for many people, in the form of personalized or location-based services, is an increasingly social and informal experience, rather than a specialist or educational experience. This is part of the transformative impact of mobility and connectedness on our societies brought about by these universal, ubiquitous and pervasive technologies. This paper contributes a revised understanding of context in the wider context (sic of the transformations taking place in our societies. These are subtle but pervasive transformations of jobs, work and the economy, of our sense of time, space and place, of knowing and learning, and of community and identity. This leads to a radical reconsideration of context as the notions of ‹self› and ‹other› are transformed.

This legal instrument of education also has a troubled historical record throughout the legal process in Congress and by the social period in which it was discussed, since the history of Brazilian education is characterized by very different events based on changes of government in each moment, so that it is presented a historical review of its creation. This law was discussed for a long time and, yet, failed to fully meet the initial needs of Brazilian education, requiring many changes since its promulgation. We consider this law an important achievement that contributes to the fight for better education, which in spite of the legal repertoire, moves to its legitimacy.

    Prekallikrein (PK) is one of the clotting factors involved in the contact phase of blood. PK has an important historical role as its deficiency state represents the second instance of a clotting defect without bleeding manifestations, the first one being factor XII deficiency. PK deficiency is a rare clotting disorder. Moreover, only 11 patients have been investigated so far by molecular biology techniques. In this article, we briefly review some of the history around PK and also present some recent data on a newly identified family from Argentina suffering from PK deficiency. Two patients are homozygous whereas other family members are heterozygous. PK activity and antigen are 1% of normal in the homozygotes and around 60 to 70% of normal in the heterozygotes. As expected, all patients are asymptomatic of bleeding or thrombosis presentations. However, the two homozygotes showed essential hypertension. The PK deficiency in this family is due to a new mutation (Arg541Gln) in exon 14. The defect segregates together with a known polymorphism, Asn124Ser, in exon 5. The significance of the presence of hypertension in the two homozygotes is discussed in view of the extra coagulation effects of PK on vasodilation, vessel permeability, and the control of blood pressure. Structure function analysis indicates that the substitution of Arg with Gln probably impedes the transmembrane diffusion of the molecule, which therefore cannot be secreted in the homozygotes. The presence of hypertension in patients with PK deficiency has been previously reported in some but not all patients. Future research activities will probably concentrate on the effect of PK and other contact phase factors on the vascular system.

    Since 1975 in order to be in conformity with the requirements of the French nuclear program, a review of historical seismicity was undertaken in France. The assessment of seismic hazard for the safety of nuclear plants is in fact based upon a seismotectonic approach which needs to take into account the seismic activity over as long a period of time as possible. The method adopted for reviewing historical earthquakes entails a systematic consultation of the original sources and a critical analysis there of in the light of the historical, geographical and political contexts of the time. The same standards apply where the acquisition of new elements of information is involved. Each item of information is assigned a degree of reliability, then compiled in a computer file, up-dated annually; this file currently contains more than 4.500 events covering a period of time of about a millenary

In § 6 of the Introduction to ‘Being and Time’ Heidegger understands that the historicity refers to the temporality of Dasein, to its finitude. Thiking of the historicity requires, as its main task, overcoming history as history of entities, in terms of history of forgotten being.

  8. Historical research in the Hanford site waste cleanup

    1992-01-01

    This paper will acquaint the audience with role of historical research in the Hanford Site waste cleanup - the largest waste cleanup endeavor ever undertaken in human history. There were no comparable predecessors to this massive waste remediation effort, but the Hanford historical record can provide a partial road map and guide. It can be, and is, a useful tool in meeting the goal of a successful, cost-effective, safe and technologically exemplary waste cleanup. The Hanford historical record is rich and complex. Yet, it poses difficult challenges, in that no central and complete repository or data base exists, records contain obscure code words and code numbers, and the measurement systems and terminology used in the records change many times over the years. Still, these records are useful to the current waste cleanup in technical ways, and in ways that extend beyond a strictly scientific aspect. Study and presentations of Hanford Site history contribute to the huge educational and outreach tasks of helping the Site's work force deal with 'culture change' and become motivated for the cleanup work that is ahead, and of helping the public and the regulators to place the events at Hanford in the context of WWII and the Cold War. This paper traces historical waste practices and policies as they changed over the years at the Hanford Site, and acquaints the audience with the generation of the major waste streams of concern in Hanford Site cleanup today. It presents original, primary-source research into the waste history of the Hanford Site. The earliest, 1940s knowledge base, assumptions and calculations about radioactive and chemical discharges, as discussed in the memos, correspondence and reports of the original Hanford Site (then Hanford Engineer Works) builders and operators, are reviewed. The growth of knowledge, research efforts, and subsequent changes in Site waste disposal policies and practices are traced. Examples of the strengths and limitations of the

    Full Text Available South African universities are in the process of serious transformation and restructuring. The place of faculties of theology at universities has come under the spotlight resulting in the closure of several theological faculties or in the moving of theology to other faculties, mainly humanities or arts. Theology is under pressure and in the current academic environment, Church History, in its traditional form, has all but disappeared from South African universities.  This article is an attempt to address the current situation. Whilst this article looks at the issue of theology at public universities, its main focus is to explore the future study of church history in the context of universities and, in particular, a Faculty of Theology. Understanding church history in the broad framework as Historical Theology, this article asserts the significance of church history at public universities, but points out the need to restructure the Department giving due consideration to community engagement, internationalisation, transformation, africanisation and interreligious collaboration. All of these would have a serious impact on teaching, learning and research.

    The impending development for the west Hawai‘i coastline adjacent to Kaloko-Honokōhau National Historical Park (KAHO) may potentially alter coastal hydrology and water quality in the marine waters of the park. Water resources are perhaps the most significant natural and cultural resource component in the park, and are critical to the health and well being of six federally listed species. KAHO contains ecosystems of brackish anchialine pools, two 11-acre fishponds, and 596 acres of coral reef habitats, all fed by groundwater originating upslope. The steep gradients on high islands, combined with typically porous substrates and high rainfall levels at upper elevations, make these settings especially vulnerable to shifts in submarine groundwater discharge (SGD) and its entrained nutrients and pollutants. Little is known about the magnitude, rate, frequency, and variability of SGD and its influence on contaminant loading to Hawaiian coastal environments. Recent studies show that groundwater flux through the park is vital to many ecosystem components including anchialine ponds and wetland biota. The function of these ecosystems may be vulnerable to changes in groundwater flow stemming from natural changes (climate and sea level) and land use (groundwater pumping and contamination). Oki and others (1999) showed that increased groundwater withdrawals for urban development since 1978 likely decreased groundwater flux to the coast by 50%. During this same time, the quality of groundwater has been vulnerable to increases in contaminant and nutrient/fertilizer additions associated with industrial, commercial and residential use upslope from KAHO (Oki and others, 1999). High-resolution measurements of waves, currents, water levels, temperature and salinity were collected in the marine portion of the park from November, 2005, through July, 2006, to establish baseline information on the magnitude, rate, frequency, and variability of SGD. These data are intended to help

    Historic districts are a special type of cultural heritage, as living cultural heritage, the utilization and development of historical districts is an inevitable issue. How to accurately position the protection and utilization of districts and achieve its healthy and sustainable development is the key work in the protection of districts. In this paper, the Internet data including Tencent's location big data are employed to study some Chinese historic and cultural streets, establish protection and development index system for historic and cultural streets, carry out in-depth study of ten core indicators, and sum up the positioning and development direction for the protection and use of districts. Historic district, as a special type of cultural heritage, is the birthplace and supporting zone of urban context, and also the place for the daily life of the general public. It boasts profound historic and humanistic background and the characteristics of a living form. As the living cultural heritage, its use and development are necessary, and attention shall also be paid to static protection and dynamic comprehensive management. But judging from the current practice, protection and use of historic districts face a host of challenges. Some districts are devoid of popularity and vitality and become cold galleries. Some districts suffer excessive development for tourism and commercialism, and lose its "original" cultural characteristics. In addition, throngs of tourists exert a negative impact on the life of the local people and the protection of immovable cultural relics. Disorderly business format and increasingly similar landscape go against the presentation of local characteristics. We should regard historic district as a dynamic urban heritage, and achieve dynamic development and protection in accordance with its inherent development laws and the principle of "step by step" through the "organic update" mode, with emphasis on the continuous comprehensive management of

    Handwritten texts carry significant information, extending beyond the meaning of their words. Modern neurology, for example, benefits from the interpretation of the graphic features of writing and drawing for the diagnosis and monitoring of diseases and disorders. This article examines how handwriting analysis can be used, and has been used historically, as a methodological tool for the assessment of medical conditions and how this enhances our understanding of historical contexts of writing. We analyze handwritten material, writing tests and letters, from patients in an early 20th-century psychiatric hospital in southern Germany (Irsee/Kaufbeuren). In this institution, early psychiatrists assessed handwriting features, providing us novel insights into the earliest practices of psychiatric handwriting analysis, which can be connected to Berkenkotter’s research on medical admission records. We finally consider the degree to which historical handwriting bears semiotic potential to explain the psychological state and personality of a writer, and how future research in written communication should approach these sources.

    2013-06-01

    Full Text Available This paper argues that transparency projects retain a political hue from the social-technological context from which they are created. Thus, radical transparency is considered as an opportunity to evolve both journalistic and democratic practices. Transparency in practice reveals diverse expectations of how journalists reporting should be used, and these expectations in turn, seem dependent on specific worldviews. This paper presents a comparative analysis of the effects of the current exemplar of radical journalism, WikiLeaks. It compares Wikileaks to its historical equivalents, including Hansard in the 18th century, and the reporting of open diplomacy in the early 20th century. This analysis shows how journalism evolves along with radical transparency projects, and how the current context of networked radical transparency can, and will, be made into news with specific political effects. In conclusion, this paper argues that practitioners should be aware of the political hues that new transparency mechanisms afford. Being cognizant of context and design choices can increase the degree to which new initiatives can have a deep systemic impact—as well as acknowledge the qualities and repercussions of that impact.

Apresentam-se a evolução histórica, o estado atual do debate e as perspectivas de desenvolvimento das teorias econômicas de oferta de educação, abarcando-se o período compreendido entre o início da década de 1960 e as contribuições mais recentes. Argumenta-se que as teorias tradicionais de economia da educação (capital humano e sinalização não deram tratamento adequado ao lado da oferta da educação. Mais tarde, os conceitos e o instrumental da microeconomia da firma foram mobilizados a fim de se tentar mapear a "tecnologia de produção de educação". A abordagem das funções de produção de educação, baseadas inicialmente apenas em insumos monetários, não foi suficiente para que se apreendesse toda a complexidade envolvida no processo de provisão de educação. Uma análise de artigos mais recentes revela três caminhos promissores para o desenvolvimento das teorias de oferta de educação: (i incluir insumos não monetários às funções de produção; (ii levar em consideração aspectos institucionais e organizacionais do sistema educativo; e (iii aprimorar as técnicas econométricas de estimação das funções de produção.

    In this paper we use three disparate examples to highlight the relevance of historical methods in the context of ethnobotany and ethnopharmacology. Unfortunately, in ethnopharmacology we have only very few examples where such historical depth is possible. On the other hand the first hand data available through ethnopharmacological research, may be of relevance for interpreting historical information. Three distinct methods were used successfully in the retrospective exploration of diachronic data. In order to gain an insight into historical developments in the use of plant species and evolution of pharmacopoeias we used a botanico-historical approach (Rosmarinus officinalis), one that combines linguistic and statistical methods (Popoluca/Mixe), and one that uses historical documentary evidence (Ch'orti). We hope that this methodological discussion encourages a wider use of such historical methods in ethnopharmacology and related areas of research.

  6. Information field for historical research

    Directory of Open Access Journals (Sweden)

    2017-09-01

    Full Text Available The article analyzes the main information collision of historical knowledge, which consists in physical inaccessibility of events and phenomena of the past as an object of historical science for a historian as an investigator. The aim of the research is to formulate and discuss a working hypothesis about the information field of historical science. The article provides an analytical background on the main ideas and approaches in the field of modern information field theory. The author carries out the projection of the main provisions of the information field theory on historical research. It is shown that the information field is a really existing information carrier that provides its acquisition, transportation, storage and visualization, as well as provides information and knowledge recorded in various forms, realizes cultural communications. One of the manifestations of such a culture is the sign systems, which determine certain contexts. Signs are characterized by polysemy. Despite artificial origin, semiotic reality is objective. Simultaneously, signs provide intellectual activity of people. Mental signs in the historical process of use by society acquire additional meanings, generating new symbols. Polysemy shapes the problem of epistemological uncertainty of two stages – identifying the problem and solving it. Historians as researchers resort to cognitive models, which, thanks to the translational function, ensure the transfer of information from the known to the unknown. One of the explanations of polysemy is the theory of conceptual integration, according to which the structures of the original mental spaces are projected onto a new, constructed, mental space – blend. This is the result of a personʼs intellectual ability to create new meanings on the basis of the available ones. Since signs and symbols are multi-valued, they form a multiplicity of retrospective scenarios of historical research at the stage of problem formulation

  7. Generative Contexts

    Science.gov (United States)

    Lyles, Dan Allen

    Educational research has identified how science, technology, engineering, and mathematics (STEM) practice and education have underperforming metrics in racial and gender diversity, despite decades of intervention. These disparities are part of the construction of a culture of science that is alienating to these populations. Recent studies in a social science framework described as "Generative Justice" have suggested that the context of social and scientific practice might be modified to bring about more just and equitable relations among the disenfranchised by circulating the value they and their non-human allies create back to them in unalienated forms. What is not known are the underlying principles of social and material space that makes a system more or less generative. I employ an autoethnographic method at four sites: a high school science class; a farm committed to "Black and Brown liberation"; a summer program geared towards youth environmental mapping; and a summer workshop for Harlem middle school students. My findings suggest that by identifying instances where material affinity, participatory voice, and creative solidarity are mutually reinforcing, it is possible to create educational contexts that generate unalienated value, and circulate it back to the producers themselves. This cycle of generation may help explain how to create systems of justice that strengthen and grow themselves through successive iterations. The problem of lack of diversity in STEM may be addressed not merely by recruiting the best and the brightest from underrepresented populations, but by changing the context of STEM education to provide tools for its own systematic restructuring.

    2016-12-01

    Full Text Available The aim of this article is to explore the historical context of vocationalism in universities. It is based on an analysis of the history of the university from a vocational perspective. It looks for evidence of vocational engagement in the activities of universities over time, taking a long view from the birth of the Western University in the Middle Ages to the 1980s with the emergence of current issues of vocationalism in university education. It adopts a chronological perspective initially and then a thematic one. The main findings are: (1 vocationalism in university education is as old as the Western University itself, (2 there is evidence from the start of the Western University of vocational engagement in terms of the provision of vocationally relevant subjects, vocationally relevant skills and the development of vocationally relevant attitudes, (3 whereas most graduate employers used to be concerned with the vocationally relevant knowledge, skills and attitudes students acquired on their degree courses, most are now more concerned with graduate capacity and disposition to learn within their employment after graduation and (4 subject-centred education is compatible with university education that supports the vocational aspirations of students.

  14. The AIDS pandemic in historic perspective.

    Science.gov (United States)

    Kazanjian, Powel

    2014-07-01

    Potent antiretroviral drugs (ART) have changed the nature of AIDS, a once deadly disease, into a manageable illness and offer the promise of reducing the spread of HIV. But the pandemic continues to expand and cause significant morbidity and devastation to families and nations as ART cannot be distributed worldwide to all who need the drugs to treat their infections, prevent HIV transmission, or serve as prophylaxis. Furthermore, conventional behavioral prevention efforts based on theories that individuals can be taught to modify risky behaviors if they have the knowledge to do so have been ineffective. Noting behavioral strategies targeting individuals fail to address broader social and political structures that create environments vulnerable to HIV spread, social scientists and public health officials insist that HIV policies must be comprehensive and also target a variety of structures at the population and environmental level. Nineteenth-century public health programs that targeted environmental susceptibility are the historical analogues to today's comprehensive biomedical and structural strategies to handle AIDS. Current AIDS policies underscore that those fighting HIV using scientific advances in virology and molecular biology cannot isolate HIV from its broader environment and social context any more than their nineteenth-century predecessors who were driven by the filth theory of disease. © The Author 2012.

  15. On the role of openness in education: A historical reconstruction

    Directory of Open Access Journals (Sweden)

    Sandra Peter

    2013-01-01

    Full Text Available In the context of education, “open(ness” has become the watermark for a fast growing number of learning materials and associated platforms and practices from a variety of institutions and individuals. Open Educational Resources (OER, Massive Open Online Courses (MOOC, and more recently, initiatives such as Coursera are just some of the forms this movement has embraced under the “open” banner. Yet, ongoing calls to discuss and elucidate the “meaning” and particularities of openness in education point to a lack of clarity around the concept. “Open” in education is currently mostly debated in the context of the technological developments that allowed it to emerge in its current forms. More in-depth explorations of the philosophical underpinnings are moved to the backstage. Therefore, this paper proposes a historical approach to bring clarity to the concept and unmask the tensions that have played out in the past. It will then show how this knowledge can inform current debates around different open initiatives.

    The aim of this paper is to reflect, in the theoretical scope, about the Vygotsky's socio-historical constructivism and the contributions from this Russian researcher to build the nursing knowledge. The Vygotskian approach has as its philosophical, epistemological and methodological purposes, the principles of the historical materialism, it emphasizes the social and cultural context in the working process, also in the use of instruments and in the dialectical interaction between human beings and environment. We understand that the ideas preconized by Vygotsky can represent an alternative method to the practical and theoretical studies, specially, as the subjective dimension of the working process near by the nursing staff.

    2015-11-01

    Full Text Available “Big Data” can revolutionize historical social science if it arises from substantively important contexts and is oriented towards answering substantively important questions. Such data may be especially important for answering previously largely intractable questions about the timing and sequencing of events, and of event boundaries. That said, “Big Data” makes no difference for social scientists and historians whose accounts rest on narrative sentences. Since such accounts are the norm, the effects of Big Data on the practice of historical social science may be more limited than one might wish.

    Science.gov (United States)

    Lombardo, P A

    2001-01-01

    This article reviews the uses of family studies carried out in the early 20th century under the banner of eugenics, a companion discipline to early genetics. It explores how, in an attempt to analyze and quantify purportedly biologic bases of social problems, the eugenicists constructed pedigree charts of notoriously "defective" families. Investigation of individuals with suspect traits formed the basis for instruction of field workers who linked those traits to larger groups. The resulting eugenic family studies provided a "scientific" face for a popular hereditarian mythology that claimed to explain all social failure in systematic terms. The eugenicists were successful in fueling public fear about the growing "army of idiots and imbeciles" graphically depicted in their pedigree charts. Their success was the result of a finely crafted educational program--propaganda that reduced science to simplistic terms. The tendency to oversimplify concepts of genetic causation and the rush to amplify the significance of research findings through the popular media is also apparent today. What begins as publicity has the potential to be transformed into propaganda. Although many in the scientific community are understandably reluctant to revisit the abuses of the past, that community must confront the history of eugenics as a necessary antidote to the genetic hype that surrounds us.

  3. Medical ethics in its American context. An historical survey.

    Science.gov (United States)

    Toulmin, S

    1988-01-01

    Until the 1950's, moral aspects of clinical practice were handled in the USA within the medical profession. Over the last 30 years, these issues have become subjects for public debate, and have changed the public perception of medicine, in four steps. In the 1950's, moral theologians questioned the implications of medical technology at the edges of life. In the late '60s and '70s, these theologians were joined by political activists, whose zeal provoked a counter-reaction from physicians. In the late '70s and early '80s, the debate became largely theoretical; but in the late '80s it is once again "clinical", though respecting the rights of patients, their families, and other nonphysicians to participate in the relevant moral decisions. In part, these four steps reflect the special feature of American social history in the last 30 years; but in part they also had counterparts in Britain and elsewhere. Either way, the monopoly control over the ethics of medical practice exercised by doctors before the 1950s is unlikely to return.

  8. A Historical Analysis of the Relationship of Faith and Science and its Significance within Education

    Science.gov (United States)

    Yegge, John G.

    Science curriculum and pedagogy are at the center of a centuries-long debate concerning the appropriate relationship of faith and science. The difficulties that science educators face seem to be based in misinformation about the historical roots of this conflict. To address that conflict, the goals of this research were to separate myth from reality and to provide a necessary context to the current tensions that are disrupting science pedagogy and curriculum content within American public schools. Working within a theoretical framework of historical literacy, this qualitative, historical analysis was a comprehensive examination of the relationship of faith and science from ancient times through the Renascence to the emergence and development of Darwinism. The historical approach methodology was utilized as a means to document the systematic examination of past events, in order to illuminate and interpret the meaning of those events. The historical record revealed that science and religion are not necessarily incompatible and that the early Christian religion provided a fertile environment in which modern science could emerge. Also noted were many instances where the record was inconsistent with what educators have commonly taught as historical fact. Finally, the complex sources of tension between modern fundamentalist Christianity and Darwinism, which has appeared as a flashpoint in public discourse within science education, were examined in depth. Based on this analysis, the study includes recommendations for educators in their approach to addressing these challenges and teaching science. This analysis can produce positive social change for educators and their students, as this information is advanced as a means to enhance historical literacy among educators and their students.

  11. Historical imagination, narrative learning and nursing practice: graduate nursing students' reader-responses to a nurse's storytelling from the past.

    Science.gov (United States)

    Wood, Pamela J

    2014-09-01

    Storytelling and narrative are widely used in nurse education and the value of narrative-based curricula, such as those governed by narrative pedagogy, is well recognised. Storytelling stimulates students' imagination, a central feature of narrative learning. One form of story and imagination yet to be fully considered by educators is the historical story and historical imagination. The use of historical storytelling creates a temporal dissonance between the story and reader that stimulates readers' imagination and response, and enables them to gain rich insights which can be applied to the present. Reader-response theory can support educators when using narrative and storytelling. This article presents an analysis of graduate nursing students' reader-responses to a nurse's story from the past. This narrative learning group used their historical imagination in responding to the story and prompted and challenged each other in their interpretation and in translating their responses to their current nursing practice. The article discusses this analysis within the context of reader-response theory and its potential application to narrative-based learning in nurse education. Historical stories stimulate historical imagination and offer a different frame of reference for students' development of textual competence and for applying insights to the present.

  16. An integrated developmental model for studying identity content in context.

    Science.gov (United States)

    Galliher, Renee V; McLean, Kate C; Syed, Moin

    2017-11-01

    Historically, identity researchers have placed greater emphasis on processes of identity development (how people develop their identities) and less on the content of identity (what the identity is). The relative neglect of identity content may reflect the lack of a comprehensive framework to guide research. In this article, we provide such a comprehensive framework for the study of the content of identity, including 4 levels of analysis. At the broadest level, we situate individual identity within historical, cultural, and political contexts, elaborating on identity development within the context of shifting cultural norms, values, and attitudes. Histories of prejudice and discrimination are relevant in shaping intersections among historically marginalized identities. Second, we examine social roles as unique and central contexts for identity development, such that relationship labels become integrated into a larger identity constellation. Third, domains of individual or personal identity content intersect to yield a sense of self in which various aspects are subjectively experienced as an integrated whole. We explore the negotiation of culturally marginalized and dominant identity labels, as well as idiosyncratic aspects of identities based on unique characteristics or group memberships. Finally, we argue that the content of identity is enacted at the level of everyday interactions, the "micro-level" of identity. The concepts of identity conflict, coherence, and compartmentalization are presented as strategies used to navigate identity content across these 4 levels. This framework serves as an organizing tool for the current literature, as well as for designing future studies on the identity development.

    CERN Document Server

    Marcum, James A

    2015-01-01

    This new edition of Thomas Kuhn's Revolution marks the 50th anniversary of the publication of Kuhn's most influential work. Drawing on the rich archival sources at MIT, and engaging fully with current scholarship, James Marcum provides the historical background to the development of The Structure of Scientific Revolutions. Exploring the shift Kuhn makes from a historical to an evolutionary philosophy of science and examining Kuhn's legacy in depth, Marcum answers key questions: What exactly was Kuhn's historiographic revolution and how did it come about? Why did it have the impact it did? What will its future impact be for both academia and society? Marcum's answers build a new portrait of Kuhn: his personality, his pedagogical style and the intellectual and social context in which he practiced his trade. Thomas Kuhn's Revolution shows how Kuhn transcends the boundaries of the philosophy of science, influencing sociologists, economists, theologians and even policy makers and politicians. This is a comprehensi...

    Full Text Available The pattern of generalization following motor learning can provide a probe on the neural mechanisms underlying learning. For example, the breadth of generalization to untrained regions of space after visuomotor adaptation to targets in a restricted region of space has been attributed to the directional tuning properties of neurons in the motor system. Building on this idea, the effect of different types of perturbations on generalization (e.g., rotation versus visual translation have been attributed to the selection of differentially tuned populations. Overlooked in this discussion is consideration of how the context of the training environment may constrain generalization. Here, we explore the role of context by having participants learn a visuomotor rotation or a translational shift in two different contexts, one in which the array of targets were presented in a circular arrangement and the other in which they were presented in a rectilinear arrangement. The perturbation and environments were either consistent (e.g., rotation with circular arrangement or inconsistent (e.g., rotation with rectilinear arrangement. The pattern of generalization across the workspace was much more dependent on the context of the environment than on the perturbation, with broad generalization for the rectilinear arrangement for both types of perturbations. Moreover, the generalization pattern for this context was evident, even when the perturbation was introduced in a gradual manner, precluding the use of an explicit strategy. We describe how current models of generalization might be modified to incorporate these results, building on the idea that context provides a strong bias for how the motor system infers the nature of the visuomotor perturbation and, in turn, how this information influences the pattern of generalization.

    Biblical Interpretation beyond Historicity evaluates the new perspectives that have emerged since the crisis over historicity in the 1970s and 80s in the field of biblical scholarship. Several new studies in the field, as well as the ‘deconstructive’ side of literary criticism that emerged from...... writers such as Derrida and Wittgenstein, among others, lead biblical scholars today to view the texts of the Bible more as literary narratives than as sources for a history of Israel.

    1991-01-01

    This paper acquaints the audience with historical waste practices and policies as they changed over the years at the Hanford Site, and with the generation of the major waste streams of concern in Hanford Site clean-up today. The paper also describes the founding and basic operating history of the Hanford Site, including World War 11 construction and operations, three major postwar expansions (1947-55), the peak years of production (1956-63), production phase downs (1964-the present), and some past suggestions and efforts to chemically treat, open-quotes fractionate,close quotes and/or immobilize Hanford's wastes. Recent events, including the designation of the Hanford Site as the open-quotes flagshipclose quotes of Department of Energy (DOE) waste remediation efforts and the signing of the landmark Hanford Federal Facility Agreement and Consent Order (Tri-Party Agreement), have generated new interest in Hanford's history. Clean-up milestones dictated in this agreement demand information about how, when, in what quantities and mixtures, and under what conditions, Hanford Site wastes were generated and released. This paper presents original, primary-source research into the waste history of the Hanford Site. The earliest, 1940s knowledge base, assumptions and calculations about radioactive and chemical discharges, as discussed in the memos, correspondence and reports of the original Hanford Site (then Hanford Engineer Works) builders and operators, are reviewed. The growth of knowledge, research efforts, and subsequent changes in Site waste disposal policies and practices are traced. Finally, the paper places the current Hanford Site waste remediation endeavors in the broad context of American and world history

    2018-01-01

    Introduction Low back pain (LBP) is a major health problem commonly requiring healthcare. In Sweden, there is a call from healthcare practitioners (HCPs) for the development, implementation and evaluation of a best practice primary healthcare model for LBP. Aims (1) To improve and understand the mechanisms underlying changes in HCP confidence, attitudes and beliefs for providing best practice coherent primary healthcare for patients with LBP; (2) to improve and understand the mechanisms underlying illness beliefs, self-care enablement, pain, disability and quality of life in patients with LBP; and (3) to evaluate a multifaceted and sustained implementation strategy and the cost-effectiveness of the BetterBack☺ model of care (MOC) for LBP from the perspective of the Swedish primary healthcare context. Methods This study is an effectiveness-implementation hybrid type 2 trial testing the hypothesised superiority of the BetterBack☺ MOC compared with current routine care. The trial involves simultaneous testing of MOC effects at the HCP, patient and implementation process levels. This involves a prospective cohort study investigating implementation at the HCP level and a patient-blinded, pragmatic, cluster, randomised controlled trial with longitudinal follow-up at 3, 6 and 12 months post baseline for effectiveness at the patient level. A parallel process and economic analysis from a healthcare sector perspective will also be performed. Patients will be allocated to routine care (control group) or the BetterBack☺ MOC (intervention group) according to a stepped cluster dogleg structure with two assessments in routine care. Experimental conditions will be compared and causal mediation analysis investigated. Qualitative HCP and patient experiences of the BetterBack☺ MOC will also be investigated. Dissemination The findings will be published in peer-reviewed journals and presented at national and international conferences. Further national dissemination and

    of educational strategies oriented to the facilitation of handicap children’s school learning. Starting from Vygotsky’s contribution to this topic and including the contributions of the Theory of the subjectivity from a historical cultural standpoint, are discussed some principles that in their systemic configuration could become a strong basis for the reorganization of some aspects concerning educational work in special education. In a first moment of the paper are discussed some conceptions and concepts developed by Vygotsky in his works “The Fundamentals of Defectology”. Concepts like the social character of the handicapped, the concepts of primary and secondary deficiency, the creative character of learning and the development of handicapped children are introduced and discussed. Following that moment are brought to the discussion some of the González Rey’s central ideas about subjectivity, emphasizing the definition of the school learning as a subjective process irreducible to intellectual skills and processes. Finally are proposed three educational implications resulted from the articulation of the two discussed theoretical approaches: the creation of new communicative scenarios oriented to the development of new subjective sense productions by children, concerning learning and their own defects, the effort to the emergence of the subject condition of the child, a position witch has been rejected by paternalistic dominant positions in this area, and the importance of a constructive, singular and interactive qualitative approach for the school processes of diagnosis and evaluation.

    Summary Current models of motor learning posit that skill acquisition involves both the formation and decay of multiple motor memories that can be engaged in different contexts [1?9]. Memory formation is assumed to be context dependent, so that errors most strongly update motor memories associated with the current context. In contrast, memory decay is assumed to be context independent, so that movement in any context leads to uniform decay across all contexts. We demonstrate that for both obj...

  6. Use of cartography in historical seismicity analysis: a reliable tool to better apprehend the contextualization of the historical documents

    Science.gov (United States)

    Thibault, Fradet; Grégory, Quenet; Kevin, Manchuel

    2014-05-01

    Historical studies, including historical seismicity analysis, deal with historical documents. Numerous factors, such as culture, social condition, demography, political situations and opinions or religious ones influence the way the events are transcribed in the archives. As a consequence, it is crucial to contextualize and compare the historical documents reporting on a given event in order to reduce the uncertainties affecting their analysis and interpretation. When studying historical seismic events it is often tricky to have a global view of all the information provided by the historical documents. It is also difficult to extract cross-correlated information from the documents and draw a precise historical context. Use of cartographic and geographic tools in GIS software is the best tool for the synthesis, interpretation and contextualization of the historical material. The main goal is to produce the most complete dataset of available information, in order to take into account all the components of the historical context and consequently improve the macroseismic analysis. The Entre-Deux-Mers earthquake (1759, Iepc= VII-VIII) [SISFRANCE 2013 - EDF-IRSN-BRGM] is well documented but has never benefited from a cross-analysis of historical documents and historical context elements. The map of available intensity data from SISFRANCE highlights a gap in macroseismic information within the estimated epicentral area. The aim of this study is to understand the origin of this gap by making a cartographic compilation of both, archive information and historical context elements. The results support the hypothesis that the lack of documents and macroseismic data in the epicentral area is related to a low human activity rather than low seismic effects in this zone. Topographic features, geographical position, flood hazard, roads and pathways locations, vineyards distribution and the forester coverage, mentioned in the archives and reported on the Cassini's map confirm this

  7. Perfumed historic buildings: Issues of authenticity

    Tošić Jovana

    2016-01-01

    Full Text Available Contemporary historical preservation practice includes olfactory preservation as an experimental method of architectural preservation. The implementation of manufactured scents in historic buildings raises important issues of authenticity. This paper focuses on three important issues in the relation between olfactory preservation and authenticity: the importance of phenomenology in memory evocation; the relative character of the authenticity concept; and the significance of social values in historic preservation. This requires a critical examination of charters, documents and theoretical interpretations which reflect a broader concept of authenticity. The paper discusses certain articles of the Venice Charter, the Nara Document on Authenticity, as well as the sense of smell in architectural experience through critical analysis of the theories of John Ruskin, Viollet-le-Duc, Roger Scruton and Juhani Pallasmaa and their concepts of authenticity. Authenticity issues are illustrated by the examples of olfactory preservation: olfactory reconstruction of Philip Johnson’s Glass House; interior restoration and olfactory reconstruction of the Arts Club in Mayfair, London; and the creation process of the perfume brand Arquiste, a meaningful example which relocates the olfactory reconstruction context. These critical analyses raise the question of scent in historic buildings as a value in itself.

    1981-01-01

    Nuclear power plants licensed in Canada have been designed to resist earthquakes: not all plants, however, have been explicitly designed to the same level of earthquake induced forces. Understanding the nature of strong ground motion near the source of the earthquake is still very tentative. This paper reviews historical and scientific accounts of the three strongest earthquakes - St. Lawrence (1925), Temiskaming (1935), Cornwall (1944) - that have occurred in Canada in 'modern' times, field studies of near-field strong ground motion records and their resultant damage or non-damage to industrial facilities, and numerical modelling of earthquake sources and resultant wave propagation to produce accelerograms consistent with the above historical record and field studies. It is concluded that for future construction of NPP's near-field strong motion must be explicitly considered in design

  12. Historical Contingency in Controlled Evolution

    Science.gov (United States)

    Schuster, Peter

    2014-12-01

    A basic question in evolution is dealing with the nature of an evolutionary memory. At thermodynamic equilibrium, at stable stationary states or other stable attractors the memory on the path leading to the long-time solution is erased, at least in part. Similar arguments hold for unique optima. Optimality in biology is discussed on the basis of microbial metabolism. Biology, on the other hand, is characterized by historical contingency, which has recently become accessible to experimental test in bacterial populations evolving under controlled conditions. Computer simulations give additional insight into the nature of the evolutionary memory, which is ultimately caused by the enormous space of possibilities that is so large that it escapes all attempts of visualization. In essence, this contribution is dealing with two questions of current evolutionary theory: (i) Are organisms operating at optimal performance? and (ii) How is the evolutionary memory built up in populations?

    The history of treatment for cryptorchidism dates back more than 200 years. This review is intended to highlight some historical aspect that led us to our current surgical treatment of this condition. The medical and historical surgical literatures pertaining to cryptorchidism were reviewed. Data sources were PubMed, Embase, conference proceedings, and bibliographies. No language, date, or publication status restrictions were imposed. The study of cryptorchidism began with the anatomical descriptions of Baron Albrecht von Haller and John Hunter. Attempts at surgical correction of the undescended testis began in the early 1800s, culminating in the first successful orchiopexy by Thomas Annandale in 1877. Max Schüller, Arthur Dean Bevan and Lattimer contributed to the establishment of current techniques for standard orchiopexy. Later, laparoscopy, high inguinal incision (Jones' approach) and scrotal approach were added to the list of current orchiopexy.

In this paper, the Internet data including Tencent’s location big data are employed to study some Chinese historic and cultural streets, establish protection and development index system for historic and cultural streets, carry out in-depth study of ten core indicators, and sum up the positioning and development direction for the protection and use of districts. Historic district, as a special type of cultural heritage, is the birthplace and supporting zone of urban context, and also the place for the daily life of the general public. It boasts profound historic and humanistic background and the characteristics of a living form. As the living cultural heritage, its use and development are necessary, and attention shall also be paid to static protection and dynamic comprehensive management. But judging from the current practice, protection and use of historic districts face a host of challenges. Some districts are devoid of popularity and vitality and become cold galleries. Some districts suffer excessive development for tourism and commercialism, and lose its “original” cultural characteristics. In addition, throngs of tourists exert a negative impact on the life of the local people and the protection of immovable cultural relics. Disorderly business format and increasingly similar landscape go against the presentation of local characteristics. We should regard historic district as a dynamic urban heritage, and achieve dynamic development and protection in accordance with its inherent development laws and the principle of “step by step” through the “organic update” mode, with emphasis on the

    The purpose of this conceptual paper is to explore and map the "espoused theories" (Argyris and Schön 1978) of agency used in educational contexts. More precisely, we limit the focus on the normative view of student agency assumed within dominant school practices, desired by educational practitioners, leaving out non-normative emerging agencies such as student agency of resistance. Agency is a "tricky" concept, and often scholars who use the concept of agency do not define or operationalize it (e.g., Archer 2000). One reason is that there is no consensus among scholars about the notion of agency, especially when applied to educational contexts (Hitlin and Elder Sociological Theory, 25 (2), 170-191, 2007). Moreover, the recent neoliberal framing of individuals' agency as fully autonomous, flexible, and self-entrepreneur is adding the dilemma of agency manipulation in the sphere of education (Gershon 2011; Sidorkin 2004). To tackle this dilemma in educational contexts, we suggest to further interrogating the normative notion of agency in all its modes and develop a more nuanced conceptualization. We hope that such conceptualization would produce an understanding of the diverse manifestations and definitions of agency within a human ideal, educational content, behaviors, and social settings. We observed diverse uses of the normative term "agency" in educational discourse. We examined the term as used by researchers and practitioners. We also looked at the different ways it has been used in philosophical discussions of education, political framing of the civic role of schooling, disciplinary policy statements, school mission statements, and in everyday common use. It is worthy to note that our categorization of the use and meaning of the normative term "agency" depends on the scholars' epistemological paradigmatic assumptions, socio-political and historical situatedness, and ontological projects being translated into diverse scholarships of education. As a result of

    Policymakers have set a goal of limiting temperature increase from human influence on the climate. This motivates the identification of decarbonization pathways to stabilize atmospheric concentrations of CO2. In this context, the future behavior of CO2 sources and sinks define the CO2 emissions necessary to meet warming thresholds with specified probabilities. We adopt a simple model of the atmosphere-land-ocean carbon balance to reflect uncertainty in how natural CO2 sinks will respond to increasing atmospheric CO2 and temperature. Bayesian inversion is used to estimate the probability distributions of selected parameters of the carbon model. Prior probability distributions are chosen to reflect the behavior of CMIP5 models. We then update these prior distributions by running historical simulations of the global carbon cycle and inverting with observationally-based inventories and fluxes of anthropogenic carbon in the ocean and atmosphere. The result is a best-estimate of historical CO2 sources and sinks and a model of how CO2 sources and sinks will vary in the future under various emissions scenarios, with uncertainty. By linking the carbon model to a simple climate model, we calculate emissions pathways and carbon budgets consistent with meeting specific temperature thresholds and identify key factors that contribute to remaining uncertainty. In particular, we show how the assumed history of CO2 emissions from land use change (LUC) critically impacts estimates of the strength of the land CO2 sink via CO2 fertilization. Different estimates of historical LUC emissions taken from the literature lead to significantly different parameterizations of the carbon system. High historical CO2 emissions from LUC lead to a more robust CO2 fertilization effect, significantly lower future atmospheric CO2 concentrations, and an increased amount of CO2 that can be emitted to satisfy temperature stabilization targets. Thus, in our model, historical LUC emissions have a

    Pyrochemical Operations began at Los Alamos National Laboratory (LANL) during 1962 (1). Electrorefining (ER) has been implemented as a routine process since the 1980’s. The process data that went through the ER operation was recorded but had never been logged in an online database. Without a database new staff members are hindered in their work by the lack of information. To combat the issue a database in Access was created to collect the historical data. The years from 2000 onward were entered and queries were created to analyze trends. These trends will aid engineering and operations staff to reach optimal performance for the startup of the new lines.

    2015-02-03

    Three extraordinary, historical documents stemming from observations made in 1697, 1803 and 1817 quote medicinal plant uses among the Fante, Ga and Ashanti people of present-day Ghana, and can be linked to original botanical specimens in European herbaria. This provides a unique opportunity to gain insight to the historical materia medica of Ghana and compare this to contemporary medicinal plant uses. By critical literary and taxonomic review, the present study (re-)establishes the earliest known history of many important Ghanaian medicinal plants, and assesses the scale of change and loss of medicinal plant knowledge in Ghana over time. The study provides the foundation to reconstruct lost or discontinued Ghanaian plant uses in local or ethnopharmacological contexts. Historical botanical specimens were located in the herbaria of University of Copenhagen Herbarium (C) and British Museum of Natural History (BM). The classification and synonymy of the specimens were updated for the study, and the historical vernacular names and medicinal uses of the plants compared with 20th/21st century literature. The plants of the historical Ga materia medica were (re-)collected to aid in semi-structured interviews. The interviews aimed to document the contemporary uses and names of the plants among the Ga, and to determine to what extent the historical medicinal uses and names are extant. The study identified 100 species in historical medicinal use in Ghana, which could be linked to 134 unique uses and 105 vernacular names in Twi (Ashanti/Fante) and Ga. Most of the plants are common in Ghana. At least 52% of the historical vernacular names appear to still be in use today. Of the specific historical uses, 41 (31%) were traced among contemporary medicinal plant uses in Ghana and represent some of the most important Ghanaian medicinal plant species. However, 93 (69%) of the historical uses could not be traced and appears to be discontinued or forgotten. Among the Ga, two medicinal

    As a new school year approaches, nurses will find themselves faced with students with symptoms of attention-deficit/hyperactivity disorder (ADHD). Navigating the diagnostic label changes and numerous psychopharmacological treatment options can prove time-consuming and confusing. The current article explores the early years of symptom identification, various diagnostic labels, and subsequent psychopharmacological treatments from psychostimulants to non-stimulant alternatives (including a prescription medical food). The current article also serves as a discussion guide for nurses and clinicians when providing education to patients and their loved ones, teachers, coaches, and others who may question the diagnosis and treatment of ADHD. This disorder can have a significant impact on one's ability to function within family, school, work, and social settings. A historical context is provided for the evolution of today's diagnostic criteria and the pharmacotherapy used in the treatment of ADHD.

  3. Identification and classification of Serbia's historic floods

    2009-01-01

    Full Text Available River flooding in Serbia is a natural phenomenon which largely exceeds the scope of water management and hydraulic engineering, and has considerable impact on the development of Serbian society. Today, the importance and value of areas threatened by floods are among the key considerations of sustainable development. As a result, flood protection techniques and procedures need to be continually refined and updated, following innovations in the fields of science and technology. Knowledge of high flows is key for sizing hydraulic structures and for gauging the cost-effectiveness and safety of the component structures of flood protection systems. However, sizing of hydraulic structures based on computed high flows does not ensure absolute safety; there is a residual flood risk and a risk of structural failure, if a flood exceeds computed levels. In hydrological practice, such floods are often referred to as historic/loads. The goal of this paper is to present a calculation procedure for the objective identification of historic floods, using long, multiple-year series of data on high flows of natural watercourses in Serbia. At its current stage of development, the calculation procedure is based on maximum annual discharges recorded at key monitoring stations of the Hydro-Meteorological Service of Serbia (HMS Serbia. When applied, the procedure results in the identification of specific historic maximum stages/floods (if any at all gauge sites included in the analysis. The probabilistic theory is then applied to assess the statistical significance of each identified historic flood and to classify the historic flood, as appropriate. At the end of the paper, the results of the applied methodology are shown in tabular and graphic form for various Serbian rivers. All identified historic floods are ranked based on their probability of occurrence (i.e., return period.

    Full Text Available EXTENDED ABSTRACT:The paper presents three language resources enabling better full-text access to digitised printed historical Slovenian texts: a hand-annotated corpus, a hand-annotated lexicon of historical words and a collection of transcribed texts. The aim of the resources is twofold: on one hand they support empirical linguistic research (corpus, collection and represent a reference tool for the research of historical Slovenian (lexicon while on the other hand they may serve as training data for the development of Human Language Technologies enabling better full-text search in digital libraries containing Slovenian written cultural heritage, modernisation of historical texts, and the development of better technological solutions for text recognition and scanning. The hand annotated corpus of historical Slovenian contains the text from 1,000 pages sampled from the years 1750 to 1900, two texts date to the end of the 16th or 17th century. The corpus contains a little more than 250,000 word tokens; each of them being annotated with hand validated linguistic features: modernised form, lemma or base form, and morhpo-syntactic description. Thus the word token »ajfram« is annotated with the normalised form »ajfrom«, by the lemma »ajfer« and morphosyntactic description »Som« or »Samostalnik« (noun, »občni« (common, »moški« (masculine and a modernised form »gorečnost« (fervour. At first the corpus was annotated automatically and then manually verified and corrected. The lexicon was created automatically from the hand-annotated corpus. It contains only attested word-forms and examples of use. The word-forms are ordered under their modern equivalents. All the modern forms of a particular word constitute a dictionary entry, defined by its lemma with conjoint information i.e. the morpho-syntactic description and the closest contemporary synonyms. Thus the entry »ajfrer/Som/gorečnost« is annotated by two modernised words »ajfra

    Full Text Available El enfoque aquí desarrollado presupone una nueva visión del mundo civilizado (Weltanschauungen. La idea del historiador de los hechos históricos presupone una visión global del mundo, a excepción de las sociedades que carecen de un lenguaje escrito. Por eso, la razón histórica discutida aquí se limita al tipo de historia que trata de civilizaciones más elevadas. El análisis de visiones del mundo aquí utilizado presupone que los símbolos son muy importantes y que pierden su poder simbólico si se cristalizan en un único sentido. Como en la teoría de Jung, un símbolo tiene la capacidad de estar activo en la mente como un transformador de la conciencia, libre de asociarse con nuevas experiencias y pensamientos. Esta teoría presta especial atención al problema de Dilthey: es decir, el problema de la calidad racional de los hechos históricos. Las visiones del mundo, que dan un significado profundo a muchos hechos históricos, se componen de símbolos y metáforas, incluyendo ideas, imágenes, valores y emociones. Estos tipos de visiones son casi todos instintivos. Es cierto que los historiadores pueden haber formulado, consciente definiciones de estos tipos de visiones del mundo así como ocurrió por las civilizaciones griega y china. Dado que la actual Weltbilt es mucho más compleja e inconsciente, se necesita algo más que una definición lógica para entenderla. Este artículo indica la forma en que puede ser alcanzada una comprensión racional de estas visiones del mundo._____________ABSTRACT:The approach here entertained presupposes a fresh theory of world pictures (Weltanschauungen of higher civilizations.

    Basavarajeeyam is an important handbook for an Ayurvedic physician of Andhra region. It is a bilingual work and the content was presented in Sanskrit and Telugu languages. With regard to the place and date of Basavarajeeyam there is no common opinion among the present day scholars. Pt Govardhana Sharma Changani in his introduction to the Sanskrit version of Basavarajeeyam exposed a historical profile of Basavrajeeyam picturising him as Basava who was a staunch follower of Veerashaivism and a contemporary of king Bijjala (end of 12(th) cent. AD). The same statement is carried out in the works of Ayurvedic Itihasa written by Atredeva Vidyawalkan and Acharya Priyavrata Sharma. It appears that the historical evidence shown by these scholars is one sided and cannot stand any reason. Basavraju stated that he had started writing this work after a thorough study of many works such as Charaka, Nithyanatheeyam (1360 AD), Revenakalpam, Pujyapadiyam, Bahatam, Kashikhandam (1435 AD) etc. Basavraju has faithfully reproduced certain chapter of Vaidyachintamani, which is considered to be a work of 15(th) century. Basavraju not only mentioned Phirangiroga in the index of diseases described by him at the end of the book, but also indicated Phirangichekka (Madhusnuhi) in the management of Meharoga and Granthi. By this evidence Basavarajiyam should be considered as the work of post Bhavaprakasha period. Basavraju indicates in the Gulmaroga Chikitsa that Sankhadravaka should be administered in the dose of 'Ekanni'. The name Ekanni was given for a copper coin which came in to circulation of money during British India produced from Madras mint (1794 AD). Based on these internal evidences, it can be safely concluded that Basavraju belong to 18(th)century.

    Full Text Available The battles that have come to this day had spectacular psychologic and psychiatric effects. Battle stres reactions in historical development phase has been mentioned with such different names as nostalgia, shell shock, soldier’s heart, Da Costra Syndrome, old sergeant syndrome, agent orange effect and post traumatic stress disorder (PTSD due to the symptoms coming into prominence. On the othere hand they do tend to show similarities (palpilation, stomach complaints, rhomatizmal aches, neurological and psychiatric symptoms, etc. in the context of symptoms and findigs. During the historical phase, the transition of methods have also infliuenced the prominent clinical characteristics of the war stress syndromes. The symptoms that arose during the gulf War have exhibited neither similarities nor explainable characteristics with previous war stress reactions of the past. Therefore, in the context of diagnostics systems, there is no clarity about where it should be incorporated. The inability to find any satisfactory organic pathology in war stress reactions have been the unchanging characteristic of the illness. In collaboration with the increasing mortality and morbidity that arise in wars it is not only an important factor but the resistance of patients, who had been effected, to amelioration is continuing to be an important concern which preoccupies governments, military authorities and doctors.

    The movie genre "snuff" appeared in the late 70s and shows the allegedly real, often cruel killing of people. More recently, a growing number of short video clips have been distributed via the internet, which also belong into this category and were clearly recognized as fictional on the basis of technical details by two study groups at the 80th Annual Meeting of the German Society of Legal Medicine held in Interlaken from 25 to 29 September 2001 (Schyma/Seidl). By means of a brief review of film history the article shows that "snuff movies" originated from a certain prevailing trend, examples of which are the murder of the actress Sharon Tate by the group around Charles Manson, the development of B horror movies, a promotional campaign for a film which flopped in 1971 (renamed several times by the distribution company from "American Cannibal" to "Snuff" to "Big Snuff") and elements of urban legends. Retrospectively there are no clues that Snuff films--i.e. movies openly distributed and actually available to the public, which were not private documentations found by the police at the homes of killers during investigations of homicides (such as in the murder series of the couple Bernardo/Homolka)--show real killings.

    Live attenuated vaccines against human viral diseases have been amongst the most successful cost effective interventions in medical history. Smallpox was declared eradicated in 1980; poliomyelitis is nearing global eradication and measles has been controlled in most parts of the world. Vaccines function well for acute diseases such as these but chronic infections such as HIV are more challenging for reasons of both likely safety and probable efficacy. The derivation of the vaccines used has in general not been purely rational except in the sense that it has involved careful clinical trials of candidates and subsequent careful follow up in clinical use; the identification of the candidates is reviewed.

  19. Cancer imaging with CEA antibodies: historical and current perspectives.

    1992-01-01

    This article reviews the history and status of cancer imaging with radiolabeled antibodies against carcinoembryonic antigen (CEA). Although CEA and many other cancer-associated antigens are not distinct for neoplasia, the quantitative increase of these markers in malignant tissues provides a sufficient differential for selective antibody targeting. Animal studies with xenografted human tumors provided the first evidence of the prospects of this technology, followed by initial clinical success with purified goat whole IgG antibodies to CEA, labeled with 131I and with the use of dual-isotope subtraction methods. Subsequently, improved and earlier imaging could be accomplished with monoclonal antibody fragments, which then would permit the use of shorter-lived radionuclides, such as 111In, 123I, and 99mTc. The preferred use of a monoclonal anti-CEA IgG Fab' fragment, labeled with 99mTc by a recently developed, simple and rapid kit, has enabled the detection of small lesions, including those in the liver, within 4 h of injection. By means of SPECT imaging, a high sensitivity and specificity for RAID could be achieved.

    Recommender systems and context awareness is currently a vital field of research. Most hybrid recommendation systems implement content based and collaborative filtering techniques whereas this work combines context and collaborative filtering. The paper presents a hybrid context aware recommender system for books and movies that gives recommendations based on the user context as well as user or item similarity. It also addresses the issue of dimensionality reduction using weighted pre filtering based on dynamically entered user context and preference of context. This unique step helps to reduce the size of dataset for collaborative filtering. Bias subtracted collaborative filtering is used so as to consider the relative rating of a particular user and not the absolute values. Cosine similarity is used as a metric to determine the similarity between users or items. The unknown ratings are calculated and evaluated using MSE (Mean Squared Error) in test and train datasets. The overall process of recommendation has helped to personalize recommendations and give more accurate results with reduced complexity in collaborative filtering.

  6. Are Historical Observations ``Ancient'' or ``Modern''?

    Griffin, R. Elizabeth

    2016-10-01

    The demarcation between ``old'', ``historic'' and ``heritage'' is fuzzy. To a large degree it depends upon purpose and usefulness, and it will always be subjective. At what point does the intrinsic value of an historic item outpace the mystique associated just with its age? When, for instance, does an ``old'' car become a ``vintage'' car? When do archived astronomical records contribute something of quantitative value to science? When can they be extricated from the realms of the museum and placed in the context of modern research? Celestial objects vary. Some do so explosively, often irreversibly; many vary periodically over time-scales from a hour or less to a century or more. Furthermore, all celestial objects change as they evolve, mostly so slowly as to be practically imperceptible, but while the general time-scale of that evolution is millions of years there are a few stages (such as the collapse from AGB towards planetary nebula and white dwarf) which happen rather suddenly, and invaluable examples of ``before-after'' can be found in some plate stores. Astrophysics has a comprehensive need to investigate the nature and time-scales of all types of change, especially ones which only access to its ``heritage'' data can describe. Surely in this day and age we have enough tools, capacity and technologies to fulfil such a basic requirement? The frustrating answer is that we do have some of the necessary tools, and most of the technologies, but as a community we lack ``capacity'' if that means manpower and funds. The problem is a technical one of accessing the older data in useable formats; it was generated by the universal change in detector technology from photography to electronic device, an exciting development in efficiency and scope that heralded a new era of research capability and data management, archiving and sharing, but it left pre-digital photographic data right out of the picture. Developments of that nature should have made research more inclusive

    Full Text Available The article reveals the urgency of the problems of revitalization and preservation of historical memory in the national and regional contexts at different stages of the past and in the present. It is shown that the historical memory of our region, like most other regions of the country, reflected the five main periods, in particular Russian, Cossack, Imperial, Soviet, modern Ukrainian. Noted that the heterogeneity of the historical memory caused rather substantial differences in the individual and collective media, despite the fact that the inhabitants of the region were a territorial community which were distinguishable features: social, ethnic, political, religious, linguistic, cultural, professional, age, sex, etc. are Focused on those key features, which caused quite stable signs of historical memory inherent in our region in different historical periods. Value is defined revival and preservation of historical memory in the development of modern national identity, the modern historical consciousness and thinking.

    Full Text Available The issue of history and historicity is reviewed in this article. The efforts of New Historicism is brought to bear on this question in an effort to find a way out of the impasse created by the modernist demand for objectivity and the postmodern resignation to radical relativism. The possibility of historiography is explored in conjunction with the pragmatic approach and leads to the conclusion that a kind of historical knowledge is attainable which can be described as useful even if not perfect. The author concurs with Crossan and his working definition of history as the past reconstructed interactively by the present through argued evidence in public discourse. The intersubjective nature of any historical enterprise leads the author to the conclusion that the search for the historical Jesus can only be done in the dialectical approach of a both ... and: both the historical Jesus and the kerygmatic Christ

    Full Text Available This study aims to understand the institutional transformation of university with historical perspective.The university has been presumed as an institution of Western civilization within a perspective that extends from medieval times to present. It is possible to identify two different university model in this time period; medieval university and modern university. Also the modern university model is divided into four sub-models within itself; German, French, English and American. Both distinctions about university are explained by the political and economic conditions of the period and the country that the university belongs. The differences pointed out by these distinctions are embodied in the context of the university’s missions and autonomy concept. A new university model called entrepreneurial university model is discussed within the context of information society in current literature. These discussions are also included at the end of the study.

    Accurate establishment of baseline conditions is critical to successful management and habitat restoration. We demonstrate the ability to robustly estimate historical fish community composition and assess the current status of the urbanized Barton Creek watershed in central Texas, U.S.A. Fish species were surveyed in 2008 and the resulting data compared to three sources of fish occurrence information: (i) historical records from a museum specimen database and literature searches; (ii) a nearly identical survey conducted 15 years earlier; and (iii) a modeled historical community constructed with species distribution models (SDMs). This holistic approach, and especially the application of SDMs, allowed us to discover that the fish community in Barton Creek was more diverse than the historical data and survey methods alone indicated. Sixteen native species with high modeled probability of occurrence within the watershed were not found in the 2008 survey, seven of these were not found in either survey or in any of the historical collection records. Our approach allowed us to more rigorously establish the true baseline for the pre-development fish fauna and then to more accurately assess trends and develop hypotheses regarding factors driving current fish community composition to better inform management decisions and future restoration efforts. Smaller, urbanized freshwater systems, like Barton Creek, typically have a relatively poor historical biodiversity inventory coupled with long histories of alteration, and thus there is a propensity for land managers and researchers to apply inaccurate baseline standards. Our methods provide a way around that limitation by using SDMs derived from larger and richer biodiversity databases of a broader geographic scope. Broadly applied, we propose that this technique has potential to overcome limitations of popular bioassessment metrics (e.g., IBI) to become a versatile and robust management tool for determining status of

  12. Hierarchical Context Modeling for Video Event Recognition.

    Current video event recognition research remains largely target-centered. For real-world surveillance videos, targetcentered event recognition faces great challenges due to large intra-class target variation, limited image resolution, and poor detection and tracking results. To mitigate these challenges, we introduced a context-augmented video event recognition approach. Specifically, we explicitly capture different types of contexts from three levels including image level, semantic level, and prior level. At the image level, we introduce two types of contextual features including the appearance context features and interaction context features to capture the appearance of context objects and their interactions with the target objects. At the semantic level, we propose a deep model based on deep Boltzmann machine to learn event object representations and their interactions. At the prior level, we utilize two types of prior-level contexts including scene priming and dynamic cueing. Finally, we introduce a hierarchical context model that systematically integrates the contextual information at different levels. Through the hierarchical context model, contexts at different levels jointly contribute to the event recognition. We evaluate the hierarchical context model for event recognition on benchmark surveillance video datasets. Results show that incorporating contexts in each level can improve event recognition performance, and jointly integrating three levels of contexts through our hierarchical model achieves the best performance.

    Several studies about tank waste contents have been published using historical records of tank transactions and various analytical measurements. While these records offer a wealth of information, the results are questionable until error estimates associated with the results can be established. However, they do provide a direction for investigation. Two principal observations from the studies are: (1) Large quantities of individual waste types from the various separations processes were widely distributed throughout the tank farms, and (2) The compositions of many of these waste types are quite distinct from one another. A key assumption associated with these observations is that the effects of time and location on the tank wastes are either nominal or not discernable. Since each waste type has a distinct composition, it would benefit all programs to better quantify that composition, and establish an uncertainty for each element of that composition. Various process, disposal, or other decisions could then be made based on current information reducing the need for extended sampling and analysis

    Mexican psychiatry initiated since pre-Hispanic times. Historically, treatments were a mixture of magic, science and religion. Ancient Nahuas had their own medical concepts with a holistic view of medicine, considering men and cosmos as a whole. The first psychiatric hospital appeared in 1566 and a more modern psychiatric asylum emerged until 1910. International exchanges of theoretical approaches started in the National University with the visit of Pierre Janet. There were other important figures that influenced Mexican psychiatry, such as Erich Fromm, Henri Ey, Jean Garrabé and Yves Thoret. Regarding Mexican psychiatrists, some of the most important contributors to Mexican psychiatry were José Luis Patiño Rojas, Manuel Guevara Oropeza and Ramón de la Fuente Muñiz. This article includes excerpts from "Clinical Psychiatry", a book by Patiño Rojas where he tries to understand and describe the inner world experienced by patients with schizophrenia; also, the thesis conducted by Guevara Oropeza ("Psychoanalisis"), which is a critical comparison between the theories of Janet and Freud. Finally, we include "The study of consciousness: current status" by Ramón de la Fuente, which leads us through the initial investigations concerning consciousness, its evolution, and the contributions made by psychology, philosophy and neurobiology.

    Full Text Available Reconstruction of the penis in transgender operations, amputation of the penis, congenital deformities and anomalies of the penis was and remains today an important issue in plastic surgery of the urogenital region. The only method to restore the penis is phalloplasty. In general, over the past decades, generations of clinicians have different ways and flaps for total fallouretheral reconstruction. Thus was formulated the characteristics of an ideal flap for the formation of neophallos, which should be safe, sensitive, without hair, and with long leg. However, despite the fact that the characteristics of a perfect flap, nowadays there is no “gold standard” in the formation of neophallos, as phalloplasty is a fairly complicated surgery, and the choice of method depends on many factors. The choice of methodology is determined by the plastics surgeon and to each patient is individual, depends on the etiology of the disease and the possibility of choosing the form of the donor’s transplant. This article presents a literature review devoted to the historical aspects of phalloplasty. In the article, in chronological order reflected the evolution of the different forming methods neofallos, phallourethrоplasty, describes their advantages and disadvantages.

    Full Text Available Antakya, known as Antioch during the ancient period, is significant among Turkey’s historical urban contexts. It is located in the south-east of Turkey, near the Syrian border and is the capital of Hatay province. Called the ‘Queen of the East’ at one time, it is an important city historically since it was an early center of Christianity and one of the capital cities of the Roman Empire. As a result of its importance, the city has been formed/re-formed over time by different empires, and many structures from various periods are still persist in the current urban form. The aim of this paper is to examine the French Mandate and Turkish Republican Period urban conservation and development strategies in Antakya in order to better understand their influences and effects on its historical urban core. The paper thus begins with an introduction and brief outline of the historical development of the core of Antakya. The second part focuses on the French Mandate and Turkish Republican Period urban conservation and development plan strategies. The final part discusses the effects of different urban development strategies on the historic core of the city.
