  2. Researching Distressing Topics

    Directory of Open Access Journals (Sweden)

    Full Text Available Qualitative researchers who explore sensitive topics may expose themselves to emotional distress. Consequently, researchers are often faced with the challenge of maintaining emotional equilibrium during the research process. However, discussion on the management of difficult emotions has occupied a peripheral place within accounts of research practice. With rare exceptions, the focus of published accounts is concentrated on the analysis of the emotional phenomena that emerge during the collection of primary research data. Hence, there is a comparative absence of a dialogue around the emotional dimensions of working with secondary data sources. This article highlights some of the complex ways in which emotions enter the research process during secondary analysis, and the ways in which we engaged with and managed emotional states such as anger, sadness, and horror. The concepts of emotional labor and emotional reflexivity are used to consider the ways in which we “worked with” and “worked on” emotion. In doing so, we draw on our collective experiences of working on two collaborative projects with ChildLine Scotland in which a secondary analysis was conducted on children’s narratives of distress, worry, abuse, and neglect.

  3. Photosynthesis, environmental change, and plant adaptation: Research topics in plant molecular ecology. Summary report of a workshop

    1995-07-01

    As we approach the 21st Century, it is becoming increasingly clear that human activities, primarily related to energy extraction and use, will lead to marked environmental changes at the local, regional, and global levels. The realized and the potential photosynthetic performance of plants is determined by a combination of intrinsic genetic information and extrinsic environmental factors, especially climate. It is essential that the effects of environmental changes on the photosynthetic competence of individual species, communities, and ecosystems be accurately assessed. From October 24 to 26, 1993, a group of scientists specializing in various aspects of plant science met to discuss how our predictive capabilities could be improved by developing a more rational, mechanistic approach to relating photosynthetic processes to environmental factors. A consensus emerged that achieving this goal requires multidisciplinary research efforts that combine tools and techniques of genetics, molecular biology, biophysics, biochemistry, and physiology to understand the principles, mechanisms, and limitations of evolutional adaptation and physiological acclimation of photosynthetic processes. Many of these basic tools and techniques, often developed in other fields of science, already are available but have not been applied in a coherent, coordinated fashion to ecological research. The efforts of this research program are related to the broader efforts to develop more realistic prognostic models to forecast climate change that include photosynthetic responses and feedbacks at the regional and ecosystem levels.

This study aims to address especifically this question, by visiting the articles published by Brazilian scholars since 1980, all of whom have been recognized and sponsored by the Brazilian National Council on Scientific and Technological Development (CNPq. Production from 80 Brazilian researchers was analysed, based on phenomena traditionally studied by Social Psychologists (e.g., Social Influence, which served as a priori categories. Articles that reflect studies developed in 5 geopolitical regions of the country, but data showed regions South and Southeast with the highest concentration in terms of academic production. Such finding is discussed in terms of the influence of an individualist culture on Brazilian research. Observing the main Social Psychology topics studied by Brazilians, it was noticed a centrality of the "Psychological" approach to Social Psychology, mainly originated in English-speaking countries.

    Full Text Available A Large number of digital text information is generated every day. Effectively searching, managing and exploring the text data has become a main task. In this paper, we first represent an introduction to text mining and a probabilistic topic model Latent Dirichlet allocation. Then two experiments are proposed - Wikipedia articles and users’ tweets topic modelling. The former one builds up a document topic model, aiming to a topic perspective solution on searching, exploring and recommending articles. The latter one sets up a user topic model, providing a full research and analysis over Twitter users’ interest. The experiment process including data collecting, data pre-processing and model training is fully documented and commented. Further more, the conclusion and application of this paper could be a useful computation tool for social and business research.

  5. Adaptation to heat and exercise performance under cooler conditions: a new hot topic.

    Science.gov (United States)

    Corbett, Jo; Neal, Rebecca A; Lunt, Heather C; Tipton, Michael J

    2014-10-01

    Chronic exposure to a stressor elicits adaptations enhancing the tolerance to that stressor. These adaptive responses might also improve tolerance under less stressful conditions. For example, historically there has been much interest in the adaptive responses to high-altitude, or hypoxia, and their ergogenic potential under sea-level, or normoxic, conditions. In contrast, the influence of the adaptive responses to heat on exercise under cooler conditions has received relatively little interest. Heat acclimation/acclimatization (HA) is known to increase work capacity in hot environments. Yet, aerobic exercise performance can progressively deteriorate as ambient temperature increases beyond ~10 °C, indicating a thermal limitation even under relatively cool conditions. The improved thermoregulatory capability induced by HA might attenuate this thermal decrement in a manner similar to that seen when exposed to hotter temperatures. Moreover, the suite of adaptations elicited by HA has the potential to increase maximal oxygen uptake, lactate threshold and economy, and thus may be ergogenic even under conditions where performance is not thermally limited. Indeed, evidence is now emerging to support an ergogenic effect of HA but the number of studies is limited and in some instances lack appropriate control, are confounded by methodological limitations, or do not address the mechanisms of action. Nevertheless, these tantalising insights into the ergogenic potential of heat will likely generate considerable interest in this new 'hot topic'. Future research will need to employ well-designed studies to clarify the exercise conditions under which ergogenic effects of HA are apparent, to elucidate the precise mechanisms, and to optimise HA strategies for performance.

  7. Characterizing interdisciplinarity of researchers and research topics using web search engines.

    Science.gov (United States)

    Sayama, Hiroki; Akaishi, Jin

    2012-01-01

    Researchers' networks have been subject to active modeling and analysis. Earlier literature mostly focused on citation or co-authorship networks reconstructed from annotated scientific publication databases, which have several limitations. Recently, general-purpose web search engines have also been utilized to collect information about social networks. Here we reconstructed, using web search engines, a network representing the relatedness of researchers to their peers as well as to various research topics. Relatedness between researchers and research topics was characterized by visibility boost-increase of a researcher's visibility by focusing on a particular topic. It was observed that researchers who had high visibility boosts by the same research topic tended to be close to each other in their network. We calculated correlations between visibility boosts by research topics and researchers' interdisciplinarity at the individual level (diversity of topics related to the researcher) and at the social level (his/her centrality in the researchers' network). We found that visibility boosts by certain research topics were positively correlated with researchers' individual-level interdisciplinarity despite their negative correlations with the general popularity of researchers. It was also found that visibility boosts by network-related topics had positive correlations with researchers' social-level interdisciplinarity. Research topics' correlations with researchers' individual- and social-level interdisciplinarities were found to be nearly independent from each other. These findings suggest that the notion of "interdisciplinarity" of a researcher should be understood as a multi-dimensional concept that should be evaluated using multiple assessment means.

    Full Text Available Text Streams are a class of ubiquitous data that came in over time and are extraordinary large in scale that we often lose track of. Basically, text streams forms the fundamental source of information that can be used to detect semantic topic which individuals and organizations are interested in as well as detect burst events within communities. Thus, intelligent system that can automatically extract interesting temporal pattern from text streams is terribly needed; however, Evolutionary Pattern Mining is not well addressed in previous work. In this paper, we start a tentative research on topic evolutionary pattern mining system by discussing fully properties of a topic after formally definition, as well as proposing a common and formal framework in analyzing text streams. We also defined three basic tasks including (1 online topic Detection, (2 event evolution extraction and (3 topic property life cycle, and proposed three common mining algorithms respectively. Finally we exemplify the application of Evolutionary Pattern Mining and shows that interesting patterns can be extracted in newswire dataset

    2013-05-01

    Full Text Available In today’s world redundancy is the most vital probl em faced in almost all domains. Novelty detection is the identification of new or unknown d ata or signal that a machine learning system is not aware of during training. The problem become s more intense when it comes to “Research Articles”. A method of identifying novelty at each sections of the article is highly required for determining the novel idea proposed in the research paper. Since research articles are semi- structured, detecting novelty of information from t hem requires more accurate systems. Topic model provides a useful means to process them and p rovides a simple way to analyze them. This work compares the most predominantly used topic mod el- Latent Dirichlet Allocation with the hierarchical Pachinko Allocation Model. The results obtained are promising towards hierarchical Pachinko Allocation Model when used fo r document retrieval.

  20. An Adaptive Updating Topic Specific Web Search System Using T-Graph

    Directory of Open Access Journals (Sweden)

    Ahmed Patel

    2010-01-01

    Full Text Available Problem statement: The main goal of a Web crawler is to collect documents that are relevant to a given topic in which the search engine specializes. These topic specific search systems typically take the whole document's content in predicting the importance of an unvisited link. But current research had proven that the document's content pointed to by an unvisited link is mainly dependent on the anchor text, which is more accurate than predicting it on the contents of the whole page. Approach: Between these two extremes, it was proposed that Treasure Graph, called T-Graph is a more effective way to guide the Web crawler to fetch topic specific documents predicted by identifying the topic boundary around the unvisited link and comparing that text with all the nodes of the T-Graph to obtain the matching node(s and calculating the distance in the form of documents to be downloaded to reach the target documents. Results: Web search systems based on this strategy allowed crawlers and robots to update their experiences more rapidly and intelligently that can also offer speed of access and presentation advantages. Conclusion/Recommendations: The consequences of visiting a link to update a robot's experiences based on the principles and usage of T-Graph can be deployed as intelligent-knowledge Web crawlers as shown by the proposed novel Web search system architecture.

    2013-12-01

    A major challenge of the research community is to provide relevant information to policymakers on vulnerability, impacts and adaptation (VIA) in the context of a changing climate, and to do so in a coherent and coordinated way. The Programme of Research on Climate Change Vulnerability, Impacts and Adaptation (PROVIA) aims to respond to this challenge by harmonizing, mobilizing, and communicating the growing knowledgebase on VIA to relevant audiences. PROVIA, in consultation with experts and policymakers, has developed a set of Research Priorities for the global VIA research community, whose activities are primarily carried out by individual researchers and research institutions. The Research Priorities include new and emerging topics as well as topics that have long been recognized as important but for which research is still required. To develop the Research Priorities, input was gathered from expert and policymaker communities through separate solicitation pathways. The expert prioritization of research topics began with a gap analysis based on existing literature. The members of the PROVIA Scientific Steering Committee (SSC) then participated in a two-day Foresight Panel that focused on determining selection criteria for inclusion in the Research Priorities, grouping the research topics into themes, and identifying additional topics. A newly framed list of 54 priority research topics was generated by compiling the SSC selections and updated findings from new literature. This list was distributed as an electronic survey to a broad group of experts in the VIA community. Respondents were asked to score each topic, provide suggestions for additional topics, and offer comments. A research prioritization process with policymakers was developed in parallel with the expert community process described above and included representatives from both developed and developing countries. The rankings of the expert and policymaker processes were then combined, along with an

  5. Research recommendations of the ESA Topical Team on Artificial Gravity

    Clément, Gilles; Bukley, Angie

    Many experts believe that artificial gravity will be required for an interplanetary mission. However, despite its attractiveness as an efficient, multi-system countermeasure and its potential for simplifying operational activities, much still needs to be learned regarding the human response to rotating environments before artificial gravity can be successfully implemented. The European Space Agency (ESA) Topical Team on Artificial Gravity recommended a comprehensive program to determine the gravity threshold required to reverse or prevent the detrimental effects of microgravity and to evaluate the effects of centrifugation on various physiological functions. Part of the required research can be accomplished using animal models on a dedicated centrifuge in low Earth orbit. Studies of human responses to centrifugation could be performed during ambulatory, short- and long-duration bed rest, and in-flight studies. Artificial-gravity scenarios should not be a priori discarded in Moon and Mars mission designs. One major step is to determine the relationship between the artificial gravity dose level, duration, and frequency and the physiological responses of the major body functions affected by spaceflight. Once its regime characteristics are defined and a dose-response curve is established, artificial gravity should serve as the standard against which all other countermeasure candidates are evaluated, first on Earth and then in space.

  18. Topical advances and recent studies in paleolimnological research

    Directory of Open Access Journals (Sweden)

    Thomas J. Whitmore

    2014-04-01

    Full Text Available Paleolimnology combines the disciplines of limnology, geology and ecology, but because of challenges that separate investigators from direct knowledge about past lake conditions, the field is multidisciplinary by necessity. As a result, paleolimnology is influenced continuously by advances in many disciplines. As with limnological studies in recent decades, paleolimnology has diverged largely from the ecological and theoretical focuses of early investigators, but recent studies demonstrate the need for more integration of ecological and paleolimnological research. This paper provides a brief overview of recent paleolimnological investigations that have addressed questions related to theoretical ecology, as well as applied lake-management and climate research issues. We examine the use of transfer function models for estimating past water-quality conditions, and important caveats expressed by investigators about limitations in the development and use of such models. Paleolimnological research has contributed new insights about biological, physical and chemical processes in lakes that have been subject to change because of climate drivers and anthropogenic influences. These findings are relevant to predicting how lakes will respond to climate change, and will require new management approaches in the future. As the range of paleolimnological studies expands, there will be greater need for basic limnological research in order for paleolimnological investigators to better understand how sediments reflect lake processes of those regions.

    2001-05-01

    A large sentence corpus has been developed for use in speech recognition research. Sentences (n=881, three scoring words per sentence) were developed under 23 topics. In the first phase of development subjects rated each individual scoring word for relatedness to its given topic on a Likert scale. Next, two groups of young, normal-hearing listeners (n=16/group) listened and responded to the recordings of the sentences (spoken by a female talker) presented with one of two types of maskers: steady-state noise (S:N=-13 dB) or two other females speaking random sentences (S:N=-8 dB). Each subject responded to half of the sentences with topic supplied and half with no topic supplied. Data analyses focused on addressing two questions: whether supplementation of topic would be more important in the presence of the speech masker versus the noise masker, and how the degree of relatedness of each key word to the topic influenced the effect of topic on recognition. The data showed little difference in how beneficial the topic was for speech versus noise maskers. Moreover, there was a complex relationship between effect of topic, type of masker, and position of the word in the sentence. [Work supported by NIDCD DC01625.

    1992-03-01

    The Gas Research Institute (GRI) Metering Research Facility (MRF) has been designed to provide two independent natural gas recirculation flow loops: a Low Pressure Loop (LPL) and High Pressure Loop (HPL). Initially, these loops can accommodate meter sizes of 1 to 6 inches and 6 to 16 inches respectively. Requirements were established for the MRF complex which consists of both loops and a building with a control room, calibration labs, and work areas. All major mechanical and electrical components were specified and engineering designs completed in sufficient detail to provide for construction and fabrication drawings. Construction of the MRF has been proposed in a staged process where each succeeding stage provides new or expanded capabilities. The report primarily concentrates on the design of Stage I of the MRF. Operating ranges for the Stage I LPL are pressures up to 200 psia, temperatures from 40 F to 120 F, flow rates to 6MMSCFD, and Reynolds number to 1.1 million. Corresponding operating ranges for the Stage I HPL are pressures to 1440 psig, temperatures from 20 F to 120 F, flow rates to 165MMSCFD, and Reynolds number in excess of 14 million. In the LPL, a state-of-the-art gyroscopic balance and computer-controlled fast acting flow diversion system provide primary mass flow measurement within an accuracy of better than 0.25%. A similar primary calibration system is planned for Stage II of the HPL.

    2010-02-01

    There is much research into problems of the elderly in The Netherlands. It seems however that studies from a macro-sociological perspective are scarce. This is discussed in greater detail focusing on the concept of power. Using a well-known definition of Max Weber, it is assumed that the dependency of many older people gives rise to serious powerlessness. Firstly this is reflected in the usual problem representation, with shows a heavy emphasis on "dangers" of the burden of the babyboom-generation and on the "leisure class-life" of old people. Second, considering the policy measures with the pensions and the care system, the question can be raised if a countervailing power is actually present. In most cases a comparison with younger cohorts is lacking, and there is not much insight in the processes underlying the decision making processes and the networks involved.

    The Delphi process, widely used in health research to seek consensus on key issues amongst large stakeholder groups, was adopted to allow families, hospice staff/volunteers and linked professionals to identify and prioritize future research priorities for children's hospice care. In the qualitative Round 1, interviews with families (n = 5), linked professionals (n = 18) and focus groups with hospice staff and volunteers (n = 44) led to the generation of 56 research topics categorised within 14 broad themes. To give a larger number of stakeholders (n = 621) (including families n = 293; hospice staff/volunteers n = 216 and professionals n = 112) the opportunity to rate the importance of each research topic and seek group consensus on the future research priorities for children's hospice care, subsequent Rounds 2 and 3 involved the use of postal questionnaires. Response rates to questionnaires were 44% in Round 2 (274/621) and 83% in Round 3 (204/247). Participants prioritized research topics relating to 1) hospice and respite care needs of young people (aged 16 +), 2) pain and symptom management and 3) bereavement and end-of-life care. There was wide acknowledgement by those took part in the process of the difficulty in rating the topics, and emphasis on the fact that all of the topics raised during the project are of high importance and merit further research. The current salient issues perceived by key stakeholders as being the research priorities for children's hospice care were identified. Addressing these priority topics for research would further contribute to the development of a much needed evidence base in children's hospice and palliative care research and optimise the delivery of children's hospice services that are underpinned by valid and robust research.

  9. Confronting international research topics with stakeholders on multifunctional land use: the case of Inner Mongolia, China

    Directory of Open Access Journals (Sweden)

    2014-12-01

    Full Text Available The established pattern of land use in the Inner Mongolia Autonomous Region is being challenged by China’s rapid overall economic transition. The provision of required land-related functions and services is subject to land management decision making. Scientific research can offer substantial support for this decision making by providing evidence of the interaction between land management and land function services. This paper’s objective was to identify the most important land use functions and services from a local perspective and to compare these functions and services with the land-related research topics addressed in the scientific literature. For this purpose, we conducted a workshop with local stakeholders (land use decision makers in the West Ujimqin Banner (Inner Mongolia as a specific case study and performed a comprehensive survey of the Inner Mongolian land use research published in international scientific journals. Our analysis indicated that the stakeholders assigned particular importance to social land use functions, such as jobs, as well as environmental land use functions and ecosystem processes. In contrast, the research topics were primarily concerned with natural science. We discussed possible shortcomings in the research agenda by emphasising and contrasting local stakeholder perspectives with the research topics and concluded that without bottom-up stakeholder participation, there would be a mismatch between the research interests of land use scientists and the needs of stakeholders. Future research that can contribute to local policy making with the aim of meeting the objectives of a multifunctional land use concept is required.

    2016-02-01

    The 2015 United Nations Climate Change Conference in Paris (COP21) highlighted the importance of cities to climate action, as well as the unjust burdens borne by the world's most disadvantaged peoples in addressing climate impacts. Few studies have documented the barriers to redressing the drivers of social vulnerability as part of urban local climate change adaptation efforts, or evaluated how emerging adaptation plans impact marginalized groups. Here, we present a roadmap to reorient research on the social dimensions of urban climate adaptation around four issues of equity and justice: (1) broadening participation in adaptation planning; (2) expanding adaptation to rapidly growing cities and those with low financial or institutional capacity; (3) adopting a multilevel and multi-scalar approach to adaptation planning; and (4) integrating justice into infrastructure and urban design processes. Responding to these empirical and theoretical research needs is the first step towards identifying pathways to more transformative adaptation policies.

    2012-07-01

    Nearly two years have passed since a small team of researchers began a new chapter in Nordic co-operation on climate change by organising a conference in Stockholm, Sweden. The conference, entitled Climate Adaptation in the Nordic Countries - Science, Practice, Policy, co-ordinated by the Stockholm Environment Institute and hosted by Stockholm University in November 2010, was the first of its kind in the Nordic region. Since the European Commission adopted its White Paper on adaptation to climate change in 2009, many of that document's 33 actions have been implemented, a climate change adaptation platform, Climate-ADAPT, was launched at the European Environment Agency in March this year, and just a week before this conference the Commission concluded a public consultation of stakeholders and experts in member states designed to feed into the preparation of a European Union adaptation strategy. The 2012 conference therefore presents an ideal opportunity to take stock of ongoing efforts and to consider how adaptation research efforts are keeping pace with policy demands as well as the needs of public and private decision-makers operating at a range of scales. It brings together researchers, public and private decision- makers, as well as those who plan and realize adaptation plans. Session themes include, among others: national and local adaptation plans, climate portals and climate services, adaptation in developing countries, legal aspects of adaptation, economic appraisal of adaptation, analysing and handling risk and uncertainty, urban planning and scenarios. The contributors have very diverse backgrounds, ranging from biosciences to social sciences, economics to geo-sciences, and engineering to architecture. Interest in climate change adaptation in the Nordic region is clearly high, with over 70% of our participants drawn from the five Nordic countries, but the conference has also managed to attract participation from further afield, with registrations

    With respect m dialectal-accented speech recognition, dialect-specific lexicon adaptation is an indispensable component to improve the performance. In this paper, a phone-based confusion matrix is adopted to obtain dialect-specific pronunciation variants. A weighting method, improved context-dependent weighting (ICDW) is proposed to characterize the pronunciation probability precisely by taking both the surface form left-context-dependency and the base form left-context-dependency into account. To make a much robust lexicon, a pruning criterion, syllable-dependent pruning (SDP), is also proposed which achieves the most effective result. In summary, the dialect-specific dialect adaptation reduces a 2.9% absolute and a 3.6% absolute in syllable error rate (SER) respectively on read speech and spontaneous speech from Shanghai-accented speakers.

    Full Text Available Over the past 30 years, policy makers and professionals who provide services to older adults with chronic conditions and impairments have placed greater emphasis on conceptualizing aging in place as an attainable and worthwhile goal. Little is known, however, of the changes in how this concept has evolved in aging research. To track trends in aging in place, we examined scholarly articles published from 1980 to 2010 that included the concept in eleven academic gerontology journals. We report an increase in the absolute number and proportion of aging-in-place manuscripts published during this period, with marked growth in the 2000s. Topics related to the environment and services were the most commonly examined during 2000–2010 (35% and 31%, resp., with a substantial increase in manuscripts pertaining to technology and health/functioning. This underscores the increase in diversity of topics that surround the concept of aging-in-place literature in gerontological research.

  8. Adaptive nonlinear control for a research reactor

    International Nuclear Information System (INIS)

    Linearization by feedback of states is based on the idea of transform the nonlinear dynamic equation of a system in a linear form. This linear behavior can be achieve well in a complete way (input state) or in partial way (input output). This can be applied to systems of single or multiple inputs, and can be used to solve problems of stabilization and tracking of references trajectories. Comparing this method with conventional ones, linearization by feedback of states is exact in certain region of the space of state, instead of linear approximations of the equations in a certain point of the operation. In the presence of parametric uncertainties in the model of the system, the introduction of adaptive schemes provide a type toughness to the control system by nonlinear feedback, which gives as result the eventual cancellation of the nonlinear terms in the dynamic relationship between the output and the input of the auxiliary control. In the same way, it has been presented the design of a nonlinearizing control for the non lineal model of a TRIGA Mark III type reactor, with the aim of tracking a predetermined power profile. The asymptotic tracking of such profile is, at the present moment, in the stage of verification by computerized simulation the relative easiness in the design of auxiliary variable of control, as well as the decoupling action of the output variable, make very attractive the utilization of the method herein presented.

    2012-12-01

    Research experiences have been shown to successfully help draw undergraduates into STEM fields. In the SOARS and RESESS summer internship programs, which focus on the atmospheric and Earth sciences respectively, we attempt to match each intern with a project that is of specific interest to them, and to place the student with a science mentor with that expertise. Initially interns are solicited before the summer on their preferred topics of interest by having applicants or reapplicants choose fields of study from a list of topics. Follow-up conversations help to better define their area of interest. We then match those with the projects that have been proposed by prospective mentors, or seek scientists in the community who do research in that subdiscipline. Mentors also evaluate the intern's course background to determine if they have the foundation necessary for that work. Interns report that the opportunity to work on a topic that they perceive as interesting is vital to their engagement in the research. One intern wrote, "One of the most important components of internships like this is definitely letting the students somewhat chose their project. I think that a really good way to turn students OFF from research is by having them spend a summer researching something they are not even close to interested in." Another commented, "I really appreciated being matched with a project in my interest area. I think that's really important, even if it just teaches you that you might want to work in a different field than you initially thought." Being immersed in such a research group or lab provides interns with a rich opportunity to learn relevant content and skills, and to start developing a professional support network. Interns continue to engage with experts in their field of interest when they present at at scientifically relevant meeting sessions during the following academic year. Many of our interns go on to study the same subdiscipline of atmospheric or Earth

    Keeping track of conceptual and methodological developments is a critical skill for research scientists, but this task is increasingly difficult due to the high rate of academic publication. As a crisis discipline, conservation science is particularly in need of tools that facilitate rapid yet insightful synthesis. We show how a common text-mining method (latent Dirichlet allocation, or topic modeling) and statistical tests familiar to ecologists (cluster analysis, regression, and network analysis) can be used to investigate trends and identify potential research gaps in the scientific literature. We tested these methods on the literature on ecological surrogates and indicators. Analysis of topic popularity within this corpus showed a strong emphasis on monitoring and management of fragmented ecosystems, while analysis of research gaps suggested a greater role for genetic surrogates and indicators. Our results show that automated text analysis methods need to be used with care, but can provide information that is complementary to that given by systematic reviews and meta-analyses, increasing scientists' capacity for research synthesis.

  11. International topical meeting on nuclear research applications and utilization of accelerators. Book of abstracts

    International Nuclear Information System (INIS)

    Applications of particle accelerators cover a number of areas, from strategic and applied research, safety and security, environmental applications, materials research and analytical sciences, to radioisotope production and radiation processing. Accelerator based techniques and pulsed neutron sources are expected to lead to new initiatives in materials research of relevance for both the nuclear and non-nuclear fields. Material science studies with the use of accelerators, neutron beams and other nuclear analytical methods are relevant to the development of advanced reactors, nuclear fuel cycle needs and fusion research. In this regard, a better understanding of the irradiation effects in materials for energy and non-energy applications is needed, and is reflected in accelerator techniques for modification and analysis of materials for nuclear technologies. Accelerator applications for innovative nuclear systems aiming at rad-waste transmutation (e.g., accelerator driven systems) are being pursued in many countries. Research and development using accelerators involves a broad spectrum of skills to build a cadre of trained experts in nuclear techniques in IAEA Member States, and to generate knowledge for innovative methodologies and tools. The present conference is also being held in cooperation with the American Nuclear Society (ANS), which successfully organized the series of accelerator applications conferences known as AccApp. The ANS series of topical meetings has provided a forum for the global exchange of scientific and technical knowledge on a wide variety of related topics since the first AccApp took place in 1997 in Albuquerque, USA. The last conference which was held in 2007 in Pocatello, USA, was jointly organized by the ANS and the IAEA. The main objectives of the conference are to promote exchange of information among IAEA Member States representatives/delegates and to discuss new trends in accelerator applications including nuclear materials research

  12. Evaluating research for clinical significance: using critically appraised topics to enhance evidence-based neuropsychology.

    2014-01-01

    Meehl's (1973, Psychodiagnosis: Selected papers. Minneapolis: University of Minnesota Press) distinction between statistical and clinical significance holds special relevance for evidence-based neuropsychological practice. Meehl argued that despite attaining statistical significance, many published findings have limited practical value since they do not inform clinical care. In the context of an ever expanding clinical research literature, accessible methods to evaluate clinical impact are needed. The method of Critically Appraised Topics (Straus, Richardson, Glasziou, & Haynes, 2011, Evidence-based medicine: How to practice and teach EBM (4th ed.). Edinburgh: Elsevier Churchill-Livingstone) was developed to provide clinicians with a "toolkit" to facilitate implementation of evidence-based practice. We illustrate the Critically Appraised Topics method using a dementia screening example. We argue that the skills practiced through critical appraisal provide clinicians with methods to: (1) evaluate the clinical relevance of new or unfamiliar research findings with a focus on patient benefit, (2) help focus of research quality, and (3) incorporate evaluation of clinical impact into educational and professional development activities.

    Full Text Available The world is faced with the challenge to feed an estimated 9 billion population of the Earth by 2050. To address the scientific evidence for the safety of food, I searched the Web of Science bibliographical and citation database for most cited articles from this research area. The topics with greatest impact on the research community, judged by their annual rate of citations during the last decade, were foodborne pathogens and toxins, with emerging genetic studies and new methods of visualising toxins on surfaces. Epidemiological and survey studies demonstrated that there was systematic effort to document, rapidly detect and control epidemic spread of disease and that these measures decreased the threat to food safety in developed countries, but that there is still much room for improvement. Research relevant for developing countries included the potential molecular targets to alleviate accumulation of arsenic in rice. As in other areas of research and life, human factor seems to be the most important one for the safety of food. The five keys to safer food of the WHO – keep clean, separate raw and cooked, cook thoroughly, keep food at safe temperatures, use safe water and raw materials – are thus still very relevant for the developed as much as the developing world.

SMASH is an academic enrichment program geared towards under-resourced, high school students of color. The goals of the course are to expand the students' conception of STEM, to teach the students that science is a method of inquiry and not just a collection of facts that are taught in school, and to expose the scholars to critical thinking within a scientific setting. The course's curriculum engages the scholars in hands-on scientific research, project proposal writing, and presentation of their scientific work to their peers as well as to a panel of UC Berkeley scientists. In this talk, we describe the course and the impact it has had on previous scholars, we discuss how the course's pedagogy has evolved over the past 10 years to enhance students' perception and understanding of science, and we present previous participants' reflections and feedback about the course and its success in providing high school students a genuine research experience at the university level.

  6. Demographic changes and the demands on agricultural landscapes: Refl ections on a new research topic

    Directory of Open Access Journals (Sweden)

    K. Müller

    2008-12-01

    Full Text Available Demographic change suggests substantial effects on future societal demands on agricultural landscape use and thus on rural areas. Demographic change is thereby defined as both the decrease of the population and the shift in the age distribution („aging“ and in the spatial distribution („rural flight“ particularly of young people. The exploration of the research object is based on the starting hypothesis that the demands and preferences of an aging and urbanizing population are changing and have effects on the controlling state interventions, which are also reflected in the agricultural use of landscapes. After a short description of demographic change, a conceptual politico-economic model, which describes the transmission of demographic change on land use, through the analysis of group (age groups, groups of residences demands on agrarian landscape use is presented. The focus is on the demand for land use related non-commodity outputs (NCO. The starting hypothesis is then examined using selected studies. The literature suggests that urban-rural dichotomy is likely to be greatly diminished. In addition, the urbanization of preferences is expected while preferences differentiated against heterogeneous cultural lifestyles seem to become even more important. However, without further research on the related topics, the basic issues cannot be clearly dealt with. Assumptions are finally made regarding changing societal demands for agrarian landscapes due to demographic change. The limitations of the selected approach and the identification of further research needs will be discussed in closing.

    Full Text Available This systematic review looks at thematic trends in clinical research publications on dental implants. For this purpose, MEDLINE electronic searches as well as additional hand searches of six main journals in the field were conducted. A total of 2875 clinical studies published between 2001 and 2012 met the inclusion criteria and were subjected to statistical analysis. Hot topics in dental implant literature included immediate loading (14.3%, bone substitutes (11.6%, cross-arch full bridges (8.0%, and immediate implant placement (7.5%. A significant increase in scientific interest for immediate loading (+6.3%, p = 0.001, platform switching (+2.9%, p = 0.001, guided implant surgery (+1.9%, p = 0.011, growth factors (p = 0.014, +1.4%, piezoelectric surgery (+1.3%, p = 0.015, and restorative materials (+0.7%, p = 0.011 was found. A declining scientific interest in onlay grafting (−0.3%, p = 0.042 was recorded.

    2015-10-01

    Nowadays, Photovoltaic module contains more high-performance components in smaller space. It is also demanded to work in severe temperature condition for special use, such as aerospace. As temperature rises, the failure rate will increase exponentially which makes reliability significantly reduce. In order to improve thermal adaptability of photovoltaic module, this paper makes a research on reinforcement technologies. Thermoelectric cooler is widely used in aerospace which has harsh working environment. So, theoretical formulas for computing refrigerating efficiency, refrigerating capacity and temperature difference are described in detail. The optimum operating current of three classical working condition is obtained which can be used to guide the design of driven circuit. Taken some equipment enclosure for example, we use thermoelectric cooler to reinforce its thermal adaptability. By building physical model and thermal model with the aid of physical dimension and constraint condition, the model is simulated by Flotherm. The temperature field cloud is shown to verify the effectiveness of reinforcement.

    Langbeheim, Elon; Safran, Samuel A.; Yerushalmi, Edit

    2013-01-01

    We present design guidelines for using Adapted Primary Literature (APL) as part of current interdisciplinary topics to introductory physics students. APL is a text genre that allows students to comprehend a scientific article, while maintaining the core features of the communication among scientists, thus representing an authentic scientific discourse. We describe the adaptation of a research paper by Nobel Laureate Paul Flory on phase equilibrium in polymer-solvent mixtures that was presented to high school students in a project-based unit on soft matter. The adaptation followed two design strategies: a) Making explicit the interplay between the theory and experiment. b) Re-structuring the text to map the theory onto the students' prior knowledge. Specifically, we map the theory of polymer-solvent systems onto a model for binary mixtures of small molecules of equal size that was already studied in class.

    2009-06-15

    The report proposes five key research themes under the heading 'Future climate and climate adaptation' which can support the Danish climate adaptation efforts. These themes underpin climate adaptation in the light of research needs identified by the research environments and sectors under the government's strategy on adaptation to climate change in Denmark from March 2008. The paper has been prepared within the framework of RESEARCH2015-proposal by the Ministry of Science, Technology and Innovation in order to bring about the knowledge and tools that are demanded by sectors and authorities to implement the government's climate adaptation strategy. This concept paper for research themes is a thorough, holistic and inter-sectoral suggestion for future research priorities in climate adaptation with anchoring in both the research community as well as in the political-administrative system. The five key themes are; 1. Models and climate adaptation; 2. Communities and climate adaptation; 3. Construction and climate adaptation; 4. Landscape and climate adaptation; 5. Climate adaptation in the coastal zone. The overall research needs over a 5 year period is estimated at 700 million DKK, of which 85 million DKK yearly can be estimated to be financed primarily through national basic funds and research council funds. Research is assumed to be coupled to external financing, for which the EU's 7th Framework Program and the Nordic excellence and innovation program in the energy, climate and environment will be significant sources.

    2015-12-01

    The gendered dimensions of climate change have received increasing interest in climate change adaptation, resilience, and vulnerability (ARV) research. Yet concerns have been expressed that engagement with ‘gender’ in this work has been tokenistic. In this context, we ask: how is climate change ARV research engaging with gender? To answer this question, we develop an assessment framework capturing key attributes of engagement and use it to evaluate peer reviewed ARV articles with a focus on gender published since 2006 (n = 123). Results indicate an increase in ARV studies with a gender focus over this period, with the level of gender engagement also increasing. There are a relatively equal numbers of studies categorized as engaging gender at a high, medium, and low level, with studies from Sub-Saharan Africa consistently exhibiting high levels of gender engagement. Gender focused ARV has a strong focus on examining female experiences, with few studies explicitly focusing on men, and no work accounting for those identifying outside the gender binary.

  3. State of research and perspective on adaptive response to low doses of ionizing radiation in Japan

    International Nuclear Information System (INIS)

    In a review article entitled ''Physical Benefits from Low Levels of Ionizing Radiation,'' published in Health Physics in December of 1982, Professor T.D. Luckey of the University of Missouri, asserted the ''radiation hormesis'' with 200 references. This resulted in the first International Symposium on Radiation Hormesis in Oakland, California (August 1985). CRIEPI consulted many specialists about Luckey's paper and studied many other papers such as Lorenz, 1954; Luckey, 1980, Liu et al., 1985. Radiation hormesis research in Japan has been based on the rationale that if Luckey's claim were to be true, radiation management in Japan has been extremely erroneous. CRIEPI organized a Hormesis Research Steering Committee composed of leading specialists in the field concerned, and began research in cooperation with a number of universities, as well as the National Cancer Research Institute, and the National Institute of Radiological Sciences. After obtaining interesting results in various experiments on the health effects of exposure to low doses of radiation, we have proceeded on an expanded program, which involves fourteen universities and two research institutes throughout Japan. The interesting results we obtained can be categorized in five groups. 1. Enhancement of immune systems such as lymphocytes and suppression of cancer, 2. Radio-adaptive response relating to the activation of DNA repair and adoptosis, 3. Rejuvenation of cells such as increase of SOD and cell membrane permeability, 4. Radiation effect on neuro-transmitting system through increase of key enzymes, 5. Others, including the therapy of adult-disease such as diabetes and hypertension. We are now carrying out experimental activities on the effects of low-dose radiation on mammals. After several years of research activities, we are recognizing Luckey's claim. Some basic surveys including Hiroshima Nagasaki and animal experiments in Japan have brought us valuable informations on the health effects of low

    Full Text Available The completion of a master’s thesis requires the advisor’s guidance on topic selection, data collection, analysis, interpretation and writing. The advisory committee’s input also contributes to the work. This study conducted content analysis and network analysis on a sample of 547 master’s theses from eight departments of the College of Journalism and Communications of Shih Hsin University to examine the relationships between the advisors and committee members as well as the connections of research topics. The results showed that the topic “lifestyle” have attracted cross-department research interests in the college. The academic network of the college is rather loose, and serving university administration duties may have broadened a faculty member’s centrality in the network. The Department of Communications Management and the Graduate Institute of Communications served as the bridges for the inter-departmental communication in the network. One can understand the interrelations among professors and departments through study on network analysis of thesis as to identify the characteristics of each department, as well as to reveal invisible relations of academic network and scholarly communication.

  11. For a better understanding of adaptive capacity to climate change: a research framework

    International Nuclear Information System (INIS)

    It is generally accepted that there exists a systematic link between a low level of adaptive capacity and a low level of development, which thus implies that the poor inevitably have low adaptive capacities. We argue here that this viewpoint is biased because adaptation to climate change is not solely determined by economic and technological capacities. Many other characteristics of a community can play a major role in its ability to react to and anticipate climate changes (e.g. the territorial identity or the social relationships). From our point of view, this limited view of adaptive capacity is related to a relative immaturity of the science of adaptation, a discipline that analyses the processes and determinants of adaptive capacity. This can be explained by the fact that there are currently few existing frameworks for studying adaptive capacity. This paper consists in a proposal for a research framework which is based upon four main fields of investigation: (i) the influential factors of adaptive capacity and their interactions, (ii) the relevant spatial and temporal scales of adaptive capacity, (iii) the links between adaptive capacity, vulnerability and the level of development and (iv) the theoretical links between adaptation and sustainability. These four fields of research should bring new knowledge on adaptive capacity and feed a more general reflection on the adaptation pathways for dealing with climate change. (author)

  12. (Post-Yugoslav anti-war engagement: A research topic awaiting attention

    2011-01-01

    Full Text Available (Post-Yugoslav anti-war contention has remained an under-theorised topic almost twenty years after the end of the wars of Yugoslav succession. Rather than focusing on the “ontogenesis” of individual pacifist enterprises, this paper examines the reasons for which (post-Yugoslav anti-war activisms have been marginalised in recent East European sociological scholarship. I argue that a thorough appreciation of these phenomena requires a Yugoslav/regional approach which has not been favoured by post-Yugoslav social science scholars. This article also offers a critical reading of the existing attempts to theorise (post- Yugoslav anti-war activisms. It criticises their failure to draw upon the rich conceptual ap­paratus of social movement theories developed within Western political sociology over the last couple of decades. In spite of the fact that the concept of “social movement” may be contested in the context of post-Yugoslav anti-war engagement on the basis of its quantitative marginality, this should not deter (post-Yugoslav social scientists from applying and refining Anglo-Saxon social movement theories in a culturally sensitive manner. Specific dynamics of anti-war activism occurring within an armed conflict has not been sufficiently studied. This is an important knowledge lacuna where regional sociologists could offer a substantive contribution.

    2016-01-01

    Background: The purpose of this study is to provide a report on scientific production during the period 2010–2014 in order to identify the major topics as well as the predominant actors (journals, countries, continents) involved in the field of eye disease. Methods: A PubMed search was carried out to extract articles related to eye diseases during the period 2010–2014. Data were downloaded and processed through developed PHP scripts for further analysis. Results: A total of 62,123 articles were retrieved. A total of 3,368 different journals were found, and 19 journals were identified as “core journals” according to Braford’s law. English was by far the predominant language. A total of 853,182 MeSH terms were found, representing an average of 13.73 (SD = 4.98) MeSH terms per article. Among these 853,182 MeSH terms, 14,689 different MeSH terms were identified. Vision Disorders, Glaucoma, Diabetic Retinopathy, Macular Degeneration, and Cataract were the most frequent five MeSH terms related to eye diseases. The analysis of the total number of publications showed that Europe and Asia were the most productive continents, and the USA and China the most productive countries. Interestingly, using the mean Five-Year Impact Factor, the two most productive continents were North America and Oceania. After adjustment for population, the overall ranking positions changed in favor of smaller countries (i.e. Iceland, Switzerland, Denmark, and New Zealand), while after adjustment for Gross Domestic Product (GDP), the overall ranking positions changed in favor of some developing countries (Malawi, Guatemala, Singapore). Conclusions: Due to the large number of articles included and the numerous parameters analyzed, this study provides a wide view of scientific productivity related to eye diseases during the period 2010–2014 and allows us to better understand this field.

    2009-12-01

    Full Text Available There have been advances in the understanding of supply chain management (SCM since its inception in the early-1980s. However, there are still some basic issues of SCM that remain unresolved. Much of the research that has been conducted takes one or more of the following three perspectives: (1 development of methods and techniques to study SCM and its components/processes; (2 developing solutions or answers to specific supply chain-related problems or challenges; and/or (3 measuring the results or outcomes of supply chain strategies and tactics. Each of these three perspectives is briefly examined, with selected examples from the literature cited to illustrate the type of research that has been conducted. Some potential areas of research exploration are presented. The areas examined include: theory development, and SCM processes and functions.

  17. What is big data? A consensual definition and a review of key research topics

    Science.gov (United States)

    De Mauro, Andrea; Greco, Marco; Grimaldi, Michele

    2015-02-01

    Although Big Data is a trending buzzword in both academia and the industry, its meaning is still shrouded by much conceptual vagueness. The term is used to describe a wide range of concepts: from the technological ability to store, aggregate, and process data, to the cultural shift that is pervasively invading business and society, both drowning in information overload. The lack of a formal definition has led research to evolve into multiple and inconsistent paths. Furthermore, the existing ambiguity among researchers and practitioners undermines an efficient development of the subject. In this paper we have reviewed the existing literature on Big Data and analyzed its previous definitions in order to pursue two results: first, to provide a summary of the key research areas related to the phenomenon, identifying emerging trends and suggesting opportunities for future development; second, to provide a consensual definition for Big Data, by synthesizing common themes of existing works and patterns in previous definitions.

  18. Fuels and Space Propellants for Reusable Launch Vehicles: A Small Business Innovation Research Topic and Its Commercial Vision

    Science.gov (United States)

    Palaszewski, Bryan A.

    1997-01-01

    Under its Small Business Innovation Research (SBIR) program (and with NASA Headquarters support), the NASA Lewis Research Center has initiated a topic entitled "Fuels and Space Propellants for Reusable Launch Vehicles." The aim of this project would be to assist in demonstrating and then commercializing new rocket propellants that are safer and more environmentally sound and that make space operations easier. Soon it will be possible to commercialize many new propellants and their related component technologies because of the large investments being made throughout the Government in rocket propellants and the technologies for using them. This article discusses the commercial vision for these fuels and propellants, the potential for these propellants to reduce space access costs, the options for commercial development, and the benefits to nonaerospace industries. This SBIR topic is designed to foster the development of propellants that provide improved safety, less environmental impact, higher density, higher I(sub sp), and simpler vehicle operations. In the development of aeronautics and space technology, there have been limits to vehicle performance imposed by traditionally used propellants and fuels. Increases in performance are possible with either increased propellant specific impulse, increased density, or both. Flight system safety will also be increased by the use of denser, more viscous propellants and fuels.

  8. Flash Flood Risk Perception in an Italian Alpine Region. From Research into Adaptive Strategies.

    Science.gov (United States)

    Scolobig, A.; de Marchi, B.; Borga, M.

    2009-04-01

    Flash floods are characterised by short lead times and high levels of uncertainty. Adaptive strategies to face them need to take into account not only the physical characteristics of the hydro-geological phenomena, but also peoples' risk perceptions, attitudes and behaviours in case of an emergency. It is quite obvious that a precondition for an effective adaptation, e.g. in the case of a warning, is the awareness of being endangered. At the same time the perceptions of those at risk and their likely actions inform hazard warning strategies and recovery programmes following such events. Usually low risk awareness or "wrong perceptions" of the residents are considered among the causes of an inadequate preparedness or response to flash floods as well as a symptom of a scarce self-protection culture. In this paper we will focus on flood risk perception and on how research on this topic may contribute to design adaptive strategies and give inputs to flood policy decisions. We will report on a flood risk perception study of the population residing in four villages in an Italian Alpine Region (Trentino Alto-Adige), carried out between October 2005 and January 2006. A total of 400 standardised questionnaires were submitted to local residents by face to face interviews. The surveys were preceded by focus groups with officers from agencies in charge of flood risk management and semi-structured and in-depth interviews with policy, scientific and technical experts. Survey results indicated that people are not so worried about hydro-geological phenomena, and think that their community is more endangered than themselves. The knowledge of the territory and danger sources, the unpredictability of flash floods and the feeling of safety induced by structural devices are the main elements which make the difference in shaping residents' perceptions. The study also demonstrated a widespread lack of adoption of preparatory measures among residents, together with a general low

  9. Balancing Constraints and the Sweet Spot as Coming Topics for Creativity Research

    DEFF Research Database (Denmark)

    Onarheim, Balder; Biskjaer, Michael Mose

    2015-01-01

    The aim of this chapter is the introduction of two new concepts, ‘balancing constraints’ and ‘the sweet spot of creativity’, as promising new paths for creativity research. This is motivated by the fact that creativity research shows a growing interest in the fundamental entwinement of constraints...... and creativity, with skillful and innovative handling of constraints seen as a prerequisite for apt creative performance. Based on a brief review of current disparate conceptualizations of constraints as both enablers and restrainers of creative activities, we begin by proposing the unifying concept ‘creativity...... constraints’ to help establish common terminological ground. Since the presence of constraints change over time, we suggest the term ‘constrainedness’ to articulate this total constraint intensity at a given time. This allows us to introduce our main contribution, the concept ‘the sweet spot’, to address...

    The aim of this chapter is the introduction of two new concepts, ‘balancing constraints’ and ‘the sweet spot of creativity’, as promising new paths for creativity research. This is motivated by the fact that creativity research shows a growing interest in the fundamental entwinement of constraints...... and creativity, with skillful and innovative handling of constraints seen as a prerequisite for apt creative performance. Based on a brief review of current disparate conceptualizations of constraints as both enablers and restrainers of creative activities, we begin by proposing the unifying concept ‘creativity...... constraints’ to help establish common terminological ground. Since the presence of constraints change over time, we suggest the term ‘constrainedness’ to articulate this total constraint intensity at a given time. This allows us to introduce our main contribution, the concept ‘the sweet spot’, to address...

    The rapidly changing requirements and business rules stimulate software developers to make their applications more dynamic, configurable, and adaptable. An effective way to meet such requirements is to apply an adaptive object-model (AOM). The AOM architecture style is composed of metamodel, model engine and tools. Firstly, two small patterns for building up metamodel are analyzed in detail. Then model engine for interpreting metamodel and tools for end-uses to define and configure object models are discussed. Finally, a novel platform-applicationware-is proposed.

    Active Data Archive Product Tracking (ADAPT) is a collection of software routines that permits one to generate XML metadata files to describe and register data products in support of the NASA Heliophysics Virtual Observatory VxO effort. ADAPT is also a philosophy. The ADAPT concept is to use any and all available metadata associated with scientific data to produce XML metadata descriptions in a consistent, uniform, and organized fashion to provide blanket access to the full complement of data stored on a targeted data server. In this poster, we present an application of ADAPT to describe all of the data products that are stored by using the Common Data File (CDF) format served out by the CDAWEB and SPDF data servers hosted at the NASA Goddard Space Flight Center. These data servers are the primary repositories for NASA Heliophysics data. For this purpose, the ADAPT routines have been used to generate data resource descriptions by using an XML schema named Space Physics Archive, Search, and Extract (SPASE). SPASE is the designated standard for documenting Heliophysics data products, as adopted by the Heliophysics Data and Model Consortium. The set of SPASE XML resource descriptions produced by ADAPT includes high-level descriptions of numerical data products, display data products, or catalogs and also includes low-level "Granule" descriptions. A SPASE Granule is effectively a universal access metadata resource; a Granule associates an individual data file (e.g. a CDF file) with a "parent" high-level data resource description, assigns a resource identifier to the file, and lists the corresponding assess URL(s). The CDAWEB and SPDF file systems were queried to provide the input required by the ADAPT software to create an initial set of SPASE metadata resource descriptions. Then, the CDAWEB and SPDF data repositories were queried subsequently on a nightly basis and the CDF file lists were checked for any changes such as the occurrence of new, modified, or deleted

  18. Compilation status and research topics in Hokkaido University nuclear reaction data centre

    International Nuclear Information System (INIS)

    The Hokkaido University Nuclear Reaction Data Centre (JCPRG) is a member of the International Network of Nuclear Reaction Data Centres (NRDC) under the auspices of the International Atomic Energy Agency (IAEA). JCPRG contributes about 10 percent of the data on charged-particle nuclear reactions in the EXFOR. In addition to the worldwide collaboration of compilation, Asian collaboration on compilation and evaluation was also promoted. As a result of this promotion, a research on the 9Be+n reaction was launched between Hokkaido University and Al-Farabi Kazakh National University. Beryllium is one of essential materials as a target window and a reflector for a spallation neutron source. The theoretical study and evaluation of the 9Be+n reaction are indispensable for nuclear engineering. We report current status of our activity and collaboration on compilation and evaluation of nuclear reaction data. (author)

    Science.gov (United States)

    Dornes, M

    1993-12-01

    In Dornes' view it is time for psychoanalytic development psychology to stand back from its preoccupation with the reconstructed child and gain access to the real child via direct observation, thus re-establishing contact with the state of research in neighbouring disciplines. Such direct observation would both stimulate a review of the cogency of the symbiosis and borderline theories of normal early development and question the assumption of lack of psychic differentiation in newborn children. So far, the author contends, psychoanalytic theory has both underestimated and overestimated the abilities of infants, ascribing to them in the latter case the capacity for complicated psychic operations (hallucinatory wish fulfillment, grandeur fantasies, projective identifications) which are in fact beyond their powers.

    Chloroplasts, the green differentiation form of plastids, are the sites of photosynthesis and other important plant functions. Genetic and genomic technologies have greatly boosted the rate of discovery and functional characterization of chloroplast proteins during the past decade. Indeed, data obtained using high-throughput methodologies, in particular proteomics and transcriptomics, are now routinely used to assign functions to chloroplast proteins. Our knowledge of many chloroplast processes, notably photosynthesis and photorespiration, has reached such an advanced state that biotechnological approaches to crop improvement now seem feasible. Meanwhile, efforts to identify the entire complement of chloroplast proteins and their interactions are progressing rapidly, making the organelle a prime target for systems biology research in plants.

  5. Key Topics for High-Lift Research: A Joint Wind Tunnel/Flight Test Approach

    Science.gov (United States)

    Fisher, David; Thomas, Flint O.; Nelson, Robert C.

    1996-01-01

    Future high-lift systems must achieve improved aerodynamic performance with simpler designs that involve fewer elements and reduced maintenance costs. To expeditiously achieve this, reliable CFD design tools are required. The development of useful CFD-based design tools for high lift systems requires increased attention to unresolved flow physics issues. The complex flow field over any multi-element airfoil may be broken down into certain generic component flows which are termed high-lift building block flows. In this report a broad spectrum of key flow field physics issues relevant to the design of improved high lift systems are considered. It is demonstrated that in-flight experiments utilizing the NASA Dryden Flight Test Fixture (which is essentially an instrumented ventral fin) carried on an F-15B support aircraft can provide a novel and cost effective method by which both Reynolds and Mach number effects associated with specific high lift building block flows can be investigated. These in-flight high lift building block flow experiments are most effective when performed in conjunction with coordinated ground based wind tunnel experiments in low speed facilities. For illustrative purposes three specific examples of in-flight high lift building block flow experiments capable of yielding a high payoff are described. The report concludes with a description of a joint wind tunnel/flight test approach to high lift aerodynamics research.

    One of the challenges that come from the development of Grid Computing applications is to predigest complicated process of compiling, deploying on the infrastructures and toolkits such as Globus Toolkit. As we explain in this article, we think it is essential to find the solution for rapid Grid Computing applications development. Gbuilder is just such a tool we worked out for rapid develop on extant Grid Computing infrastructure platforms. By using Gbuilder, applications should be able to react dynamically to different infrastructures and toolkits. Since WS-Resource Framework (WSRF) specifications provide technique standard to developers to declare and implement the association between Web service and one or more stateful resources, we aim at making infrastructures provide WS-Resource according these specifications automatically by adding a middleware. This paper focuses on the adapting mechanisms that are provided as the lowermost component of Gbuilder. First we study the adapting model for Globus Toolkit in patterns of combination dynamic and static. Then it describes how to apply the dynam-static adaptation flexibly to adjust different infrastructures to provide WS-Resource based on WSRF. At last, it comes along the conclusion and we give out our future works.

  9. Hydrogen from biomass: state of the art and research challenges; TOPICAL

    International Nuclear Information System (INIS)

    appropriate feedstocks and deployment scenarios that match hydrogen to the local markets. Co-production opportunities are of particular interest for near-term deployment since multiple products improve the economics; however, co-product development is not covered in this report. Biomass has the potential to accelerate the realization of hydrogen as a major fuel of the future. Since biomass is renewable and consumes atmospheric CO2 during growth, it can have a small net CO2 impact compared to fossil fuels. However, hydrogen from biomass has major challenges. There are no completed technology demonstrations. The yield of hydrogen is low from biomass since the hydrogen content in biomass is low to being with (approximately 6% versus 25% for methane) and the energy content is low due to the 40% oxygen content of biomass. Since over half of the hydrogen from biomass comes from splitting water in the steam reforming reaction, the energy content of the feedstock is an inherent limitation of the process . The low yield of hydrogen on a weight basis is misleading since the energy conversion efficiency is high. However, the cost for growing, harvesting, and transporting biomass is high. Thus even with reasonable energy efficiencies, it is not presently economically competitive with natural gas steam reforming for stand-alone hydrogen without the advantage of high-value co-products. Additionally, as with all sources of hydrogen, production from biomass will require appropriate hydrogen storage and utilization systems to be developed and deployed. The report also looked at promising areas for further research and development. The major areas for R,D and D are: feedstock preparation and feeding; gasification gas conditioning; system integration; modular systems development; valuable co-product integration; and larger-scale demonstrations. These are in addition to the challenges for any hydrogen process in storage and utilization technologies

  10. Adapting Western research methods to indigenous ways of knowing.

    Science.gov (United States)

    Simonds, Vanessa W; Christopher, Suzanne

    2013-12-01

    Indigenous communities have long experienced exploitation by researchers and increasingly require participatory and decolonizing research processes. We present a case study of an intervention research project to exemplify a clash between Western research methodologies and Indigenous methodologies and how we attempted reconciliation. We then provide implications for future research based on lessons learned from Native American community partners who voiced concern over methods of Western deductive qualitative analysis. Decolonizing research requires constant reflective attention and action, and there is an absence of published guidance for this process. Continued exploration is needed for implementing Indigenous methods alone or in conjunction with appropriate Western methods when conducting research in Indigenous communities. Currently, examples of Indigenous methods and theories are not widely available in academic texts or published articles, and are often not perceived as valid.

    1992-05-01

    The Mineral Resources Institute at the University of Alabama, along with investigators from the University of Pittsburgh and the University of Nevada-Reno, have conducted a research program on the beneficiation, of Eastern oil shales. The objective of the research program was to evaluate and adapt those new and emerging technologies that have the potential to improve the economics of recovering oil from Eastern oil shales. The technologies evaluated in this program can be grouped into three areas: fine grinding kerogen/mineral matter separation, and waste treatment and disposal. Four subtasks were defined in the area of fine grinding. They were as follows: Ultrasonic Grinding, Pressure Cycle Comminution, Stirred Ball Mill Grinding, and Grinding Circuit Optimization. The planned Ultrasonic grinding research was terminated when the company that had contracted to do the research failed. Three technologies for effecting a separation of kerogen from its associated mineral matter were evaluated: column flotation, the air-sparged hydrocyclone, and the LICADO process. Column flotation proved to be the most effective means of making the kerogen/mineral matter separation. No problems are expected in the disposal of oil shale tailings. It is assumed that the tailings will be placed in a sealed pond and the water recycled to the plant as is the normal practice. It may be advantageous, however, to conduct further research on the recovery of metals as by-products and to assess the market for tailings as an ingredient in cement making.

  12. Helping fluid teams work: A research agenda for effective team adaptation in healthcare.

    Bedwell, Wendy L; Ramsay, P Scott; Salas, Eduardo

    2012-12-01

    Although membership changes within teams are a common practice, research into this phenomenon is relatively nascent (Summers et al.; Acad Manag J 55:314-338, 2012). The small literature base, however, does provide insight into skills required for effective adaptation. The purpose of this effort is to provide a brief research synopsis, leading to research hypotheses about medical team training. By generalizing previous scientific findings regarding skills required for effective membership adaptation in different kinds of teams, we posit mechanisms whereby teamwork training might also support adaptation among medical teams (Burke et al.; Qual & Saf Health Care 13:i96-i104, 2004 and Salas et al.; Theor Issues Ergon Sci 8:381-394, 2007). We provide an overview of the membership change literature. Drawing upon literature from both within and outside of the medical domain, we suggest a framework and research propositions to aid in research efforts designed to determine the best content for helping to create adaptable medical teams through team training efforts. For effective adaptation, we suggest ad hoc teams should be trained on generalizable teamwork skills, to share just "enough" and the "right" information, to engage in shared leadership, and to shift from explicit to implicit coordination. Our overarching goal was to present what is known from the general research literature on successful team adaptation to membership changes, and to propose a research agenda to evaluate whether findings generalize to member changes in medical teams.

    From dealing with the inherent uncertainties in outcomes of scientific research to the lack of applicability of current NASA Procedural Requirements guidance documentation, research-based projects present challenges that require unique application of classical project management techniques. If additionally challenged by the creation of a new program transitioning from basic to applied research in a technical environment often unfamiliar with the cost and schedule constraints addressed by project management practices, such projects can find themselves struggling throughout their life cycles. Finally, supplying deliverables to a prime vehicle customer, also in the formative stage, adds further complexity to the development and management of research-based projects. The Biomedical Research and Countermeasures Projects Branch at NASA Johnson Space Center encompasses several diverse applied research-based or research-enabling projects within the newly-formed Human Research Program. This presentation will provide a brief overview of the organizational structure and environment in which these projects operate and how the projects coordinate to address and manage technical requirements. We will identify several of the challenges (cost, technical, schedule, and personnel) encountered by projects across the Branch, present case reports of actions taken and techniques implemented to deal with these challenges, and then close the session with an open forum discussion of remaining challenges and potential mitigations.

    NC code or STL file can be generated directly from measuring data in a fast reverse-engineering mode.Compressing the massive data from laser scanner is the key of the new mode.An adaptive compression method based on triangulated-surfaces model is put forward.Normal-vector angles between triangles are computed to find prime vertices for removal.Ring data structure is adopted to save massive data effectively.It allows the efficient retrieval of all neighboring vertices and triangles of a given vertices.To avoid long and thin triangles,a new re-triangulation approach based on normalized minimum-vertex-distance is proposed,in which the vertex distance and interior angle of triangle are considered.Results indicate that the compression method has high efficiency and can get reliable precision.The method can be applied in fast reverse engineering to acquire an optimal subset of the original massive data.

    The Ribble Rivers Trust leads a partnership of land and water management organisations that use a holistic approach to water management in the Ribble catchment. They are interested in incorporating sustainable stormwater systems, into their program of delivery with a view to ensuring that their activities to improve the environments and habitats of the catchment also contribute to reducing flood risk. A methodology, to locate interventions that would slow water within the catchment are identified; however partner buy in, institutional caution and economic barriers are felt to be hindering delivery. In response a transdisciplinary research project in which both the academics of the University of Liverpool and the practitioners of The Ribble Rivers Trust are active investigators has been established. The project aims to increase the uptake of sustainable stormwater management techniques through the analysis of the institutional, experiential and governance processes and their interactions with the physical hydrological processes governing stormwater systems. Research that is transdisciplinary must integrate academic knowledge with practitioner, local understanding and practice. Furthermore methodologies belonging to different academic fields must be blended together to collect, analyse and interpret data in order to examine complex problems through different disciplinary lenses in an integrated way. This approach has been developed in response to the complex relationships of cause and effect of contemporary inter-related economic, environmental and societal challenges. There have been a number of challenges to overcome as transdisciplinary researchers, the first and most important was to understand the different research philosophies and theoretical assumptions behind various natural science and social science research methods. Without this understanding research methodologies could be flawed and would not be effectively integrated and the data would not be

    2013-01-01

    Spanish-speaking Mexican Americans (MAs) need representation in cancer research studies to provide an empirical base for developing culturally relevant health care interventions. One factor that limits research with MAs is the lack of Spanish language measurement tools. Bilingual, bicultural student research assistants (RAs), working with faculty researchers and translation consultants, adapted the English version Distress Thermometer and Problem List (DT-PL) tool into the Spanish language. Additionally, RAs assessed tool feasibility with five MA women to determine its usefulness for a later study. The translation process resulted in a distress assessment instrument suitable for use in a low-literacy, Spanish-speaking population. RAs can enhance a process of adapting a measurement tool for use in research. Health care researchers should now pilot the Spanish DT-PL tool to assess its reliability and validity.

    Cold-adapted microorganisms such as psychrotrophs and psychrophiles widely exist in the soils of sub-Arctic, Arctic, Antarctic, alpine, and high mountains, being the important microbial resources for the biodegradation of petroleum hydrocarbons at low temperature. Using the unique advantage of cold-adapted microorganisms to the bioremediation of petroleum hydrocarbon-contaminated soils in low temperature region has become a research hotspot. This paper summarized the category and cold-adaptation mechanisms of the microorganisms able to degrade petroleum hydrocarbon at low temperature, biodegradation characteristics and mechanisms of different petroleum fractions under the action of cold-adapted microorganisms, bio-stimulation techniques for improving biodegradation efficiency, e. g., inoculating petroleum-degrading microorganisms and adding nutrients or bio-surfactants, and the present status of applying molecular biotechnology in this research field, aimed to provide references to the development of bioremediation techniques for petroleum hydrocarbon-contaminated soils.

  7. Spotlight Topics

    Science.gov (United States)

    A Spotlight Topic consists of a set of two or more review articles focused on a specific subject in surface science. The topics are recommended by the Board of Editors. A topic may be chosen because it is particularly new or fast-breaking, thus deserving introduction to the general readership. Or, it may be because a topic is especially controversial or confusing, requiring clarification by experts. Each review will give a critical assessment rather than an encyclopedic report. While our editors always will insist on fairness and accuracy, any review which forwards an opinion is bound to be somewhat subjective. Therefore, it is the editors' wish that the set of reviews written by different authors on the same subject matter will provide a broad and balanced viewpoint. It is often the case that an author who is an expert in a technique or method may be especially enthusiastic or critical about this technique or method. A companion review in the set may provide a different viewpoint. We are hopeful that the reader, after studying these reviews and checking some of the key references, will obtain an informed opinion of the subject. We think the set of reviews in a spotlight area will considerably shorten the ``learning time'' that a nonexpert would otherwise need to become knowledgeable about a subject. In this issue, we feature a spotlight topic on oxide surfaces. The set contains an overview article by Jacques Jupille, and four articles written by G. Pacchioni, F. Cosandey and T. E. Madey, B. G. Daniels, R. Lindsay and G. Thornton, and C. Noguera respectively. Of these, the article by Pacchioni has already appeared in SRL 7, 277 (2000). The other three articles appear in this issue. A reader who wishes to suggest a spotlight topic or recommend authors to write such reviews should contact the Editor-in-Chief. We would like to hear from you.

  13. Planning adaptation for food and farming: lessons from 40 year's research

    Energy Technology Data Exchange (ETDEWEB)

    Reid, Hannah; Chambwera, Muyeye; Murray, Laurel

    2012-05-15

    Local farmers and pastoralists in poor countries have long coped with droughts, floods and variable rainfall patterns. This first-hand experience is invaluable for those working on climate change adaptation policies, but how do we access it? The International Institute for Environment and Development (IIED) has 40 years' experience working alongside vulnerable communities to help inform regional, national and global policies. Our research has shown that measures to increase climate change resilience must view food, energy, water and waste management systems as interconnected and mutually dependent. This holistic approach must also be applied to economic analysis on adaptation planning. Similarly, it is vital to use traditional knowledge and management skills, which can further support adaptation planning. Taking these lessons into account, we can then address the emerging policy challenges that we face.

  14. Social and natural sciences differ in their research strategies, adapted to work for different knowledge landscapes.

    Science.gov (United States)

    Jaffe, Klaus

    2014-01-01

    Do different fields of knowledge require different research strategies? A numerical model exploring different virtual knowledge landscapes, revealed two diverging optimal search strategies. Trend following is maximized when the popularity of new discoveries determine the number of individuals researching it. This strategy works best when many researchers explore few large areas of knowledge. In contrast, individuals or small groups of researchers are better in discovering small bits of information in dispersed knowledge landscapes. Bibliometric data of scientific publications showed a continuous bipolar distribution of these strategies, ranging from natural sciences, with highly cited publications in journals containing a large number of articles, to the social sciences, with rarely cited publications in many journals containing a small number of articles. The natural sciences seem to adapt their research strategies to landscapes with large concentrated knowledge clusters, whereas social sciences seem to have adapted to search in landscapes with many small isolated knowledge clusters. Similar bipolar distributions were obtained when comparing levels of insularity estimated by indicators of international collaboration and levels of country-self citations: researchers in academic areas with many journals such as social sciences, arts and humanities, were the most isolated, and that was true in different regions of the world. The work shows that quantitative measures estimating differences between academic disciplines improve our understanding of different research strategies, eventually helping interdisciplinary research and may be also help improve science policies worldwide.

    2006-08-15

    As part of a long-term effort to both improve access to information on climate change and freshwater resources, and to understand the state of the science, we compiled an electronic bibliography of scientific literature in that area. We analyzed the distribution of information on climatic impacts on freshwater resources, with an emphasis on differences between developed and developing regions as well as differences in the types and focus of research carried out among regions. There has been more research overall in developed countries than in the developing world. Proportionally more of the available research on natural and human systems pertains to developed regions, while most of the analysis done in developing countries is limited to higher-level climatology and hydrology. We argue that scientific information and understanding are important elements of the ability to adapt to potential climatic changes. The distribution of the scientific literature in our database suggests that the types of science most directly relevant to adaptive capacity are skewed towards developed countries, which may exacerbate existing disparities in adaptive capacity, and ultimately worsen the consequences of climatic impacts in developing countries.

    2010-01-01

    Full Text Available This introspective essay was inspired by a desire to reflect on the use of qualitative research methods--where I am a Caucasian woman examining work experiences of women of color. I launched a journey backward to discover respondents' motivation for participating in my focus groups over the years, to closely examine their comfort level with a cross-ethnic dyad. The exercise enabled me to reflect on how I had negotiated power issues inherent in the research process. It contributes to the ongoing dialogue about autoethnography--where understanding of self in socio-cultural context is both the subject and object of the research enterprise. Overall, I interrogate epistemological and methodological practicalities of researching difference.

    1982-02-01

    Recently there has been little interest in topical contraceptives. The most popular are the cervical cap and the diaphragm. Other types of mechanical contraceptive devices are being investigated. Standley and Kessler have developed a device for introduction into the cervical canal with a reservoir of spermatocide, it does not block the flow of blood during menstruation. New models of vaginal rings are also being developed which are simple enough for self-insertion and also contain a reservoir of spermatocide. Work is being done on spermatocide-containing sponges in many countries. Another project being investigated is the possibility of using natural proteins, collagens, and other substances which absorb spermatozoids. The ancients used various vaginal suppositories to kill spermatozoids; in the late 19th century quinine sulfate was used for this, and a variety of substances have been used recently. These spermicidal creams also have the advantage of acting as anti-infectious agents in many cases. But they do have some negative effects. They are about 85% effective, are local irritants, and some cause discomfort during intercourse. And it is possible that some are resorbed by the body and act on the liver and other organs. Vaginal globules and suppositories are also popular. The "Kontraceptin-T" brand contains quinosol, boric acid, and tannin. There are also foaming tablets which are mixed with water and then introduced. New locally-active chemical substances are being developed in Japan, West Germany, and the USSR. Kontraceptin-E contains paranonyl-phenoxypolyethylene glycol and sodium dioctylsulfosuccinate. The "Norforks" and other preparations contain mercurial compounds which may turn out to be harmful. The future promises the development of products which will act to prevent fertilization by acting on the hyaluronidase and the acrosine of the spermatozoid, thus preventing it from penetrating the ovum. It would be best to find enzyme inhibitors which are

  2. Genomic resources for a model in adaptation and speciation research: characterization of the Poecilia mexicana transcriptome

    Kelley Joanna L

    2012-11-01

    Full Text Available Abstract Background Elucidating the genomic basis of adaptation and speciation is a major challenge in natural systems with large quantities of environmental and phenotypic data, mostly because of the scarcity of genomic resources for non-model organisms. The Atlantic molly (Poecilia mexicana, Poeciliidae is a small livebearing fish that has been extensively studied for evolutionary ecology research, particularly because this species has repeatedly colonized extreme environments in the form of caves and toxic hydrogen sulfide containing springs. In such extreme environments, populations show strong patterns of adaptive trait divergence and the emergence of reproductive isolation. Here, we used RNA-sequencing to assemble and annotate the first transcriptome of P. mexicana to facilitate ecological genomics studies in the future and aid the identification of genes underlying adaptation and speciation in the system. Description We provide the first annotated reference transcriptome of P. mexicana. Our transcriptome shows high congruence with other published fish transcriptomes, including that of the guppy, medaka, zebrafish, and stickleback. Transcriptome annotation uncovered the presence of candidate genes relevant in the study of adaptation to extreme environments. We describe general and oxidative stress response genes as well as genes involved in pathways induced by hypoxia or involved in sulfide metabolism. To facilitate future comparative analyses, we also conducted quantitative comparisons between P. mexicana from different river drainages. 106,524 single nucleotide polymorphisms were detected in our dataset, including potential markers that are putatively fixed across drainages. Furthermore, specimens from different drainages exhibited some consistent differences in gene regulation. Conclusions Our study provides a valuable genomic resource to study the molecular underpinnings of adaptation to extreme environments in replicated sulfide

    Full Text Available Compared with Space-Time Adaptive Processing (STAP, Space-Time Adaptive Detection (STAD employs the data in the cell under test and those in the training to form reasonable detection statistics and consequently decides whether the target exists or not. The STAD has concise processing procedure and flexible design. Furthermore, the detection statistics usually possess the Constant False Alarm Rate (CFAR property, and hence it needs no additional CFAR processing. More importantly, the STAD usually exhibits improved detection performance than that of the conventional processing, which first suppresses the clutter then adopts other detection strategy. In this paper, we first summarize the key strongpoint of the STAD, then make a classification for the STAD, and finally give some future research tracks.

    2011-04-01

    Full Text Available Climate change and air pollution are two of the anthropogenic stressors that require international collaboration. Influence mechanisms and combating strategies towards them have similarities to some extent. Impacts of air pollution and climate change have long been studied under IUFRO Research Group 7.01 and state of the art findings are presented at biannual meetings. Monitoring, modelling, assessment of multiple stressors, ecophysiology, and nutrient cycles have been thoroughly studied aspects of climate change and air pollution research for a long time under the umbrella of IUFRO RG 7.01. Recently, social and economic issues together with water relations are gaining more attention in parallel with science requirements on adaptation. In this paper, we summarise the main research needs emphasized at the recent 24th IUFRO RG 7.01 Conference titled “Adaptation of Forest Ecosystems to Air Pollution and Climate Change”. One important conclusion of the conference was the need for information on nutritional status of forest stands for sustainable forest management. It has been suggested to maintain long-term monitoring programs and to account for the effects of extreme years, and past and present management practices. Long-term monitoring can also help to understand the effects of forestry treatments on the nutrient and water budgets of the ecosystems which may enable to improve management practices like water saving silviculture.

    Ground control is one of the four subsystems of underground mining. It covers not only roof control, but also rib control, floor control, pillar design, shield design, overburden failures and subsidence. In the past three decades, ground control has made a tremendous advancement and many case studies have demon-strated its important role in the daily mining operations. However, there are plenty of room for improve-ments. This paper discusses the research needs in 12 subject areas including research approach, rock property, geology, computer modeling, in-situ stresses, roof bolting, coal pillars, field instrumentation, failures, surface subsidence, shield supports and coal bumps.

    Mishra, Srikanta; Schuetter, Jared

    2014-11-01

    We compare two approaches for building a statistical proxy model (metamodel) for CO₂ geologic sequestration from the results of full-physics compositional simulations. The first approach involves a classical Box-Behnken or Augmented Pairs experimental design with a quadratic polynomial response surface. The second approach used a space-filling maxmin Latin Hypercube sampling or maximum entropy design with the choice of five different meta-modeling techniques: quadratic polynomial, kriging with constant and quadratic trend terms, multivariate adaptive regression spline (MARS) and additivity and variance stabilization (AVAS). Simulations results for CO₂ injection into a reservoir-caprock system with 9 design variables (and 97 samples) were used to generate the data for developing the proxy models. The fitted models were validated with using an independent data set and a cross-validation approach for three different performance metrics: total storage efficiency, CO₂ plume radius and average reservoir pressure. The Box-Behnken–quadratic polynomial metamodel performed the best, followed closely by the maximin LHS–kriging metamodel.

    Full Text Available Participatory research has in recent years become a popular approach for problem-oriented scientific research that aims to tackle complex problems in a real management context. Within the European Union project NeWater, stakeholder processes were initiated in seven case studies to develop approaches for adaptive water management. The Uzbek part of the Amudarya River basin was one of the studied river basins. However, given the current political and cultural context in Uzbekistan, which provides little room for stakeholder participation, it was unclear to what extent participation could be realized there. In this paper, we present an evaluation of the participatory research carried out in the Amudarya case study with respect to (i the choice and application of different participatory methods and their adaptation to the given political, socioeconomic, and cultural environment, (ii their usefulness in improving system understanding and developing strategies and measures to improve water management and monitoring, and (iii their acceptance and suitability for enhancing policy-making processes in the Amudarya River basin context. The main lessons learned from the comparison of the different participatory methods were (1 the stakeholder process provided an opportunity for meetings and discussions among stakeholders from different organizational levels and thus promoted communication between different levels and organizations, and (2 in a context where most stakeholders are not generally involved in policy-making, there is a danger of raising expectations that a research project cannot meet, e.g., of transferring local interests to higher levels. Our experience shows that in order to choose participatory methods and adapt them to the Uzbek cultural and political setting (and most likely this applies to other post-Soviet transition countries as well, four aspects should be taken into account: the time required to prepare and apply the method, good

    Full Text Available Because of the jamming signal is real-time changeable and control algorithm cannot timely tracking control flywheel rotor, this paper takes vehicle maglev flywheel battery as the research object. One kind of dual-model control strategy is developed based on the analysis of the vibration response impact of the flywheel battery control system. In view of the complex foundation vibration problems of electric vehicles, the nonlinear dynamic simulation model of vehicle maglev flywheel battery is solved. Through analyzing the nonlinear vibration response characteristics, one kind of dual-mode adaptive hybrid control strategy based on H∞ control and unbalance displacement feed-forward compensation control is presented and a real-time switch controller is designed. The reliable hybrid control is implemented, and the stability in the process of real-time switch is solved. The results of this project can provide important basic theory support for the research of vehicle maglev flywheel battery control system.

  2. Ground-Based Research on Vestibular Adaptation to G-Level Transitions

    At TNO research is ongoing on neuro-vestibular adaptation to altered G-levels. It is well-known that during the first days in weightlessness 50-80% of all astronauts suffer from the Space Adaptation Syndrome (SAS), which involves space motion sickness, spatial disorientation and motion illusions. After return on Earth the problems re-appear, but now also accompanied by postural imbalance. Standard tests for motion sickness, typically applied in astronaut selection programs, do not correlate with SAS at all. TNO developed a method which effectively simulates SAS on Earth, by exposing astronauts to a hypergravity stimulus of 3G in a human centrifuge for one hour. So far we tested the susceptibility for SIC in 12 astronauts and cosmonauts who also rated their susceptibility for SAS in actual spaceflight. The correlation is 100%, suggesting a common mechanism for any G-level transition, whether it is from 1G to 0G or from 3G to 1G. This paper describes the current status of this research.

  3. Adaptive Water Governance: Assessing the Institutional Prescriptions of Adaptive (Co-Management from a Governance Perspective and Defining a Research Agenda

    2009-06-01

    Full Text Available This article assesses the institutional prescriptions of adaptive (co-management based on a literature review of the (water governance literature. The adaptive (co-management literature contains four institutional prescriptions: collaboration in a polycentric governance system, public participation, an experimental approach to resource management, and management at the bioregional scale. These prescriptions largely resonate with the theoretical and empirical insights embedded in the (water governance literature. However, this literature also predicts various problems. In particular, attention is called to the complexities associated with participation and collaboration, the difficulty of experimenting in a real-world setting, and the politicized nature of discussion on governance at the bioregional scale. We conclude this article by outlining a common research agenda that invites the collaborative efforts of adaptive (co-management and governance scholars.

    Low temperature and drought are the main environmental factors threatening the animals living in arctic area and cold temperate regions. To adapt the severe environment, the animals should adopt appropriate strategies. As a group of arthopods with freeze-avoiding strategy, soil springtails have the similar ecological mechanisms and modes of cold resistance/tolerance as insects, manifesting in the cold acclimation and drought tolerance to decrease the damage of ice crystal formation. During cold acclimation, there are a rapid increase of glycerol, a rapid decrease of fucose and glucose, and the production of anti-freeze proteins (AFP) , and exists the inter-transformation of different kinds of lipids to improve the flow of cell membrane to protect the cell from low temperature injury. In addition, soil springtails have their own specific modes and mechanisms to tolerate low temperature stress, mainly the vertical migration under the protection of snow cover and the excretion of ice nucleator from haemolymph, illustrating that it's of significance to research the cryobiology of soil springtails. This paper summarized the modes and mechanisms of soil springtails in tolerating low temperature environment, reviewed the research progress on the eco-physiology of the springtails, discussed the existing problems of the researches on the low temperature tolerance of the springtails, and prospected the research directions of the springtails low temperature ecology under the background of global change.

    2012-09-05

    The Department of Energy’s High Temperature, Low Relative Humidity Membrane Program was begun in 2006 with the Florida Solar Energy Center (FSEC) as the lead organization. During the first three years of the program, FSEC was tasked with developing non-Nafion® proton exchange membranes with improved conductivity for fuel cells. Additionally, FSEC was responsible for developing protocols for the measurement of in-plane conductivity, providing conductivity measurements for the other funded teams, developing a method for through-plane conductivity and organizing and holding semiannual meetings of the High Temperature Membrane Working Group (HTMWG). The FSEC membrane research focused on the development of supported poly[perfluorosulfonic acid] (PFSA) – Teflon membranes and a hydrocarbon membrane, sulfonated poly(ether ether ketone). The fourth generation of the PFSA membrane (designated FSEC-4) came close to, but did not meet, the Go/No-Go milestone of 0.1 S/cm at 50% relative humidity at 120 °C. In-plane conductivity of membranes provided by the funded teams was measured and reported to the teams and DOE. Late in the third year of the program, DOE used this data and other factors to decide upon the teams to continue in the program. The teams that continued provided promising membranes to FSEC for development of membrane electrode assemblies (MEAs) that could be tested in an operating fuel cell. FSEC worked closely with each team to provide customized support. A logic flow chart was developed and discussed before MEA fabrication or any testing began. Of the five teams supported, by the end of the project, membranes from two of the teams were easily manufactured into MEAs and successfully characterized for performance. One of these teams exceeded performance targets, while the other requires further optimization. An additional team developed a membrane that shows great promise for significantly reducing membrane costs and increasing membrane lifetime.

    2016-09-01

    Parent Management Training-Oregon Model (PMTO(®) ) is a set of theory-based parenting programs with status as evidence-based treatments. PMTO has been rigorously tested in efficacy and effectiveness trials in different contexts, cultures, and formats. Parents, the presumed agents of change, learn core parenting practices, specifically skill encouragement, limit setting, monitoring/supervision, interpersonal problem solving, and positive involvement. The intervention effectively prevents and ameliorates children's behavior problems by replacing coercive interactions with positive parenting practices. Delivery format includes sessions with individual families in agencies or families' homes, parent groups, and web-based and telehealth communication. Mediational models have tested parenting practices as mechanisms of change for children's behavior and found support for the theory underlying PMTO programs. Moderating effects include children's age, maternal depression, and social disadvantage. The Norwegian PMTO implementation is presented as an example of how PMTO has been tailored to reach diverse populations as delivered by multiple systems of care throughout the nation. An implementation and research center in Oslo provides infrastructure and promotes collaboration between practitioners and researchers to conduct rigorous intervention research. Although evidence-based and tested within a wide array of contexts and populations, PMTO must continue to adapt to an ever-changing world. PMID:27283222

    Maintaining contact with and collecting outcome data from adolescent study participants can present a significant challenge for researchers conducting longitudinal studies. Establishing an organized and effective protocol for participant follow-up is crucial to reduce attrition and maintain high retention rates. This paper describes our methods in using and adapting the evidence-based Engagement, Verification, Maintenance, and Confirmation (EVMC) model to follow up with adolescents 6 and 12 months after implementation of a health program. It extends previous research by focusing on two key modifications to the model: (1) the central role of cell phones and texting to maintain contact with study participants throughout the EVMC process and, (2) use of responsive two-way communication between staff and participants and flexible administration modes and methods in the confirmation phase to ensure that busy teens not only respond to contacts, but also complete data collection. These strategies have resulted in high overall retention rates (87-91%) with adolescent study participants at each follow-up data collection point without the utilization of other, more involved tracking measures. The methods and findings presented may be valuable for other researchers with limited resources planning for or engaged in collecting follow-up outcome data from adolescents enrolled in longitudinal studies.

    Full Text Available The biomedical information environment is in a state of constant and rapid change due to the increase in research data and rapid technological advances. In Taiwan, few research has investigated the information literacy of biomedical graduate students. This exploratory study examined the information literacy abilities and training of biomedical graduate students in Taiwan. Semi-structured interviews based on the Association of College and Research Libraries Information Literacy Competency Standards for Science and Engineering/Technology were conducted with 20 molecular biological graduate students. The interview inquired about their information-seeking channels and information literacy education. The findings show that the biomedical graduate students developed a workable thesis topic with their advisors. Through various information-seeking channels and retrieval strategies, they obtained and critically evaluated information to address different information needs for their thesis research. Through seminars, annual conferences and papers, the interviewees were informed of current developments in their field. Subsequently, through written or oral communications, they were able to integrate and exchange the information. Most interviewees cared about the social, economic, legal, and ethical issues surrounding the use of information. College courses and labs were the main information literacy education environment for them to learn about research skills and knowledge. The study concludes four areas to address for the information literacy of biomedical graduate students, i.e., using professional information, using the current information, efficiency in assessing the domain information, and utilization of diverse information channels. Currently, the interviewees showed rather low usage of library resources, which is a concern for biomedical educators and libraries. [Article content in Chinese

  17. Topic Model for Graph Mining.

    2015-12-01

    Graph mining has been a popular research area because of its numerous application scenarios. Many unstructured and structured data can be represented as graphs, such as, documents, chemical molecular structures, and images. However, an issue in relation to current research on graphs is that they cannot adequately discover the topics hidden in graph-structured data which can be beneficial for both the unsupervised learning and supervised learning of the graphs. Although topic models have proved to be very successful in discovering latent topics, the standard topic models cannot be directly applied to graph-structured data due to the "bag-of-word" assumption. In this paper, an innovative graph topic model (GTM) is proposed to address this issue, which uses Bernoulli distributions to model the edges between nodes in a graph. It can, therefore, make the edges in a graph contribute to latent topic discovery and further improve the accuracy of the supervised and unsupervised learning of graphs. The experimental results on two different types of graph datasets show that the proposed GTM outperforms the latent Dirichlet allocation on classification by using the unveiled topics of these two models to represent graphs.

    This topical issue of Physica Scripta collects selected peer-reviewed contributions based on invited and contributed talks and posters presented at the 15th Central European Workshop on Quantum Optics (CEWQO) which took place in Belgrade 29 May-3 June 2008 (http://cewqo08.phy.bg.ac.yu). On behalf of the whole community took place in Belgrade 29 May-3 June 2008 (http://cewqo08.phy.bg.ac.yu, cewqo08.phy.bg.ac.yu). On behalf of the whole community of the workshop, we thank the referees for their careful reading and useful suggestions which helped to improve all of the submitted papers. A brief description of CEWQO The Central European Workshop on Quantum Optics is a series of conferences started informally in Budapest in 1992. Sometimes small events transform into important conferences, as in the case of CEWQO. Professor Jozsef Janszky, from the Research Institute of Solid State Physics and Optics, is the founder of this series. Margarita Man'ko obtained the following information from Jozsef Janszky during her visit to Budapest, within the framework of cooperation between the Russian and Hungarian Academies of Sciences in 2005. He organized a small workshop on quantum optics in Budapest in 1992 with John Klauder as a main speaker. Then, bearing in mind that a year before Janszky himself was invited by Vladimir Buzek to give a seminar on the same topic in Bratislava, he decided to assign the name 'Central European Workshop on Quantum Optics', considering the seminar in Bratislava to be the first workshop and the one in Budapest the second. The third formal workshop took place in Bratislava in 1993 organized by Vladimir Buzek, then in 1994 (Budapest, by Jozsef Janszky), 1995 and 1996 (Budmerice, Slovakia, by Vladimir Buzek), 1997 (Prague, by Igor Jex), 1999 (Olomouc, Czech Republic, by Zdenek Hradil), 2000 (Balatonfüred, Hungary, by Jozsef Janszky ), 2001 (Prague, by Igor Jex), 2002 (Szeged, Hungary, by Mihaly Benedict), 2003 (Rostock,Germany, by Werner Vogel and

  5. International topical meeting on research reactor fuel management (RRFM) - United States Foreign Research Reactor (FRR) Spent Nuclear Fuel (SNF) acceptance program: 2007 update

    International Nuclear Information System (INIS)

    The Nuclear Weapons Non-proliferation Policy Concerning Foreign Research Reactor Spent Nuclear Fuel, adopted by The United States Department of Energy (DOE), in consultation with the Department of State in May 1996, has been extended to expire May 12, 2016, providing an additional 10 years to return fuel to the U.S. This paper provides a brief update on the program, now transferred to the National Nuclear Security Administration (NNSA), and discusses program initiatives and future activities. The goal of the program continues to be recovery of nuclear materials (27 countries have participated so far, returning a total of 7620 spent nuclear fuel elements), which could otherwise be used in weapons, while assisting other countries to enjoy the benefits of nuclear technology. More than ever before, DOE and reactor operators need to work together to schedule shipments as soon as possible, to optimize shipment efficiency over the remaining years of the program. The NNSA is seeking feedback from research reactor operators to help us understand ways to include eligible reactor who have not yet participated in the program

    2012-12-01

    Climate change could significantly impact the personal and operations of federal coastal laboratories. The Goddard Institute for Space Studies has made downscaled climate projections for Hampton Roads, Virginia a coastal region which includes NASA Langley Research Center (LaRC). These projections are being used to formulate adaptation and mitigation strategies to reduce climate change impacts at the center. Sea level rise and hurricanes will have significant impacts on LaRC and strategies such as surge modeling and tide gauge measurements and now underway. A proposed windbreak will reduce the impact of hurricane winds on center infrastructure. Disease vectors such as mosquitoes and ticks are being monitored and studied for their response to climate change. LaRC has significant forest and ecosystems which will be impacted by climate change and these impacts are being quantified. Mitigation strategies are being proposed such as the design of a 3 MW solar photovoltaic array to protect the center from brownouts and loss of power to critical missions. These and other programs will be discussed to reduce climate change impacts and allow LaRC to accomplish its mission into the next century.

  11. The future of topical analgesics.

    Science.gov (United States)

    Arnstein, Paul M

    2013-07-01

    Topically applied analgesic therapies have been used throughout history to treat a variety of patient conditions that present with pain. Before modem pharmaceuticals became readily available, mud-based emollients, salves, cold therapies, and other natural remedies were often used. Now we have effective therapies and are developing advanced topical analgesics as we learn more about the physiology and pathophysiology of pain. The use of topical analgesics may be associated with fewer patient systemic side effects than are seen with oral, parenteral, or transdermally administered agents, making the topical route of administration attractive to prescribers and patients. With further refinement of existing drugs and the development of novel agents, topical analgesics may offer relief for treating patient pain conditions that are currently challenging to treat, such as pain resulting from burns, wound debridement, and pressure ulcers. Recognizing the value of a multimodal approach, topical analgesics may offer a therapeutic option that can become part of a comprehensive treatment plan for the patient. With continued advancements in targeted drug-delivery systems, topical analgesics may be able to provide a method to prevent or reverse the phenomena of peripheral and central sensitization, or the neuroplastic changes believed to be responsible for the transition from acute to chronic pain states in patients. For those patients at risk for developing chronic pain states, such as complex regional pain syndrome, the combination of cutaneous stimulation (achieved through rubbing during application) and analgesic effects produced by the drug itself may prevent the disabling pain that often emerges during the subacute phase of disease. In summary, better utilization of currently available topical analgesics and continued research promise to ensure that topical analgesics are, and will continue to be, important tools in the treatment of patients with resistant pain.

    We propose the Adaptive Leadership Framework for Chronic Illness as a novel framework for conceptualizing, studying, and providing care. This framework is an application of the Adaptive Leadership Framework developed by Heifetz and colleagues for business. Our framework views health care as a complex adaptive system and addresses the intersection at which people with chronic illness interface with the care system. We shift focus from symptoms to symptoms and the challenges they pose for patients/families. We describe how providers and patients/families might collaborate to create shared meaning of symptoms and challenges to coproduce appropriate approaches to care. PMID:25647829

  16. Reduced analysis and confirmatory research on co-adaptability theoretical solution to conflicting events in construction engineering projects

    Institute of Scientific and Technical Information of China (English)

    2010-01-01

    The co-adaptability theoretical solution to conflicting events in construction engineering projects has three problems. First, the transformation of constraint conditions of theoretical solution is very difficult in practical engineering applications; second, some coefficients are difficult to be determined; third, there are overfull circular arithmetic operations involved in it. To resolve these problems, a new method to reduce the theoretical solution complications is proposed. By analyzing the operating mechanism of theoretical solution model, redundancies in the theoretical solution can be eliminated, and the ISM mapping with the co-adaptability solution can be set up. Based on this approach, a procedure to solve practical conflicting events in construction projects is established by replacing characteristic variables with mathematic variables. The research results show that the procedure can replace the co-adaptability theoretical solution effectively and solve practical conflicting events in construction projects.

    2014-01-01

    This article reviews the research at the Department of Human Biology at the Christian-Albrechts-University in Kiel since 2006. The research focuses on the investigation of recent human populations with respect to aging, chronobiology, and adaptation to high altitude. The research areas are outlined presenting findings, ongoing projects and future directions. Aging research examines biological changes in humans considering that aging is a multidimensional process. Changes in body composition, resting energy metabolism, oxidative stress, and sleep have been examined. The applicability of specific research methods to older people has been tested. Chronobiological research concentrates on investigating circadian rhythms of humans. The emphasis lies on the sleep-wake rhythm, body temperature rhythms, hormonal rhythms (cortisol and melatonin) and the circadian expression of so-called clock genes which are involved in the generation of circadian rhythms. Association studies examine the relationship between defined chronobiological phenotypes and clock gene polymorphisms. Genetic aspects are as well investigated within the third research area on the adaptation of native populations to life at high altitude in the South American Andes. Both candidate gene analysis and epigenetic parameters are investigated. Future research will concentrate on the aging of the circadian system. PMID:24818445

    2006-01-01

    The study of atomic physics propelled us into the quantum age in the early twentieth century and carried us into the twenty-first century with a wealth of new and, in some cases, unexplained phenomena. Topics in Atomic Physics provides a foundation for students to begin research in modern atomic physics. It can also serve as a reference because it contains material that is not easily located in other sources. A distinguishing feature is the thorough exposition of the quantum mechanical hydrogen atom using both the traditional formulation and an alternative treatment not usually found in textbooks. The alternative treatment exploits the preeminent nature of the pure Coulomb potential and places the Lenz vector operator on an equal footing with other operators corresponding to classically conserved quantities. A number of difficult to find proofs and derivations are included as is development of operator formalism that permits facile solution of the Stark effect in hydrogen. Discussion of the classical hydrogen...

    demonstrated range of validity of soundproof models, showing that they are more broadly applicable than some had previously thought. Substantial testing of EULAG included application and extension of the Jablonowski-Williamson baroclinic wave test - an archetype of planetary weather - and further analysis of multi-scale interactions arising from collapse of temperature fronts in both the baroclinic wave test and simulations of the Held-Suarez idealized climate. These analyses revealed properties of atmospheric gravity waves not seen in previous work and further demonstrated the ability of EULAG to simulate realistic behavior over several orders of magnitude of length scales. Additional collaborative work enhanced capability for modeling atmospheric flows with adaptive moving meshes and demonstrated the ability of EULAG to move into petascale computing. 3b. CAM-EULAG Advances We have developed CAM-EULAG in collaboration with former project postdoc, now University of Cape Town Assistant Professor, Babatunde Abiodun. Initial study documented good model performance in aqua-planet simulations. In particular, we showed that the grid adaptivity (stretching) implemented in CAM-EULAG allows higher resolution in selected regions without causing anomalous behavior such as spurious wave reflection. We then used the stretched-grid version to analyze simulated extreme precipitation events in West Africa, comparing the precipitation and event environment with observed behavior. The model simulates fairly well the spatial scale and the interannual and intraseasonal variability of the extreme events, although its extreme precipitation intensity is weaker than observed. In addition, both observations and the simulations show possible forcing of extreme events by African easterly waves. 3c. Other Contributions Through our collaborations, we have made contributions to a wide range of outcomes. For research focused on terrestrial behavior, these have included (1) upwind schemes for gas dynamics

    Full Text Available Topic maps are an ISO standard (ISO 13250 that is used for presenting the information about information resources structures. The initial idea of this standard was raised in 1991 and due to its strength; it turned into an ISO standard. This paper investigates concepts and model of topic maps and aims to mention applications of this standard in library and information science (LIS realm. A topic map, as a type of document is defined as XML or SGML technically. Research show that this standard is compatible with some of LIS techniques and rules especially in knowledge organization, but it attempts to use these rules in the web. So it can be said that according to some challenges that LIS field faces in adapting traditional techniques for knowledge organization in the Web, topic maps standard can help in solving such problems and challenges and this is what some experts of LIS tried to do.

    2014-02-01

    Full Text Available This paper presents an adaptive controller equipped with a stiffness estimation method for a novel material-testing machine, in order to alleviate the performance depression caused by the stiffness variance of the tested specimen. The dynamic model of the proposed machine is built using the Kane method, and the kinematic model is established with a closed-form solution. The stiffness estimation method is developed based on the recursive least-squares method and the proposed stiffness equivalent matrix. Control performances of the adaptive controller are simulated in detail. The simulation results illustrate that the proposed controller can greatly improve the control performance of the target material-testing machine by online stiffness estimation and adaptive parameter tuning, especially in low-cycle fatigue (LCF and high-cycle fatigue (HCF tests.

  7. The burgeoning field of transdisciplinary adaptation research in Quebec (1998-): a climate change-related public health narrative.

    2011-01-01

    This paper presents a public health narrative on Quebec's new climatic conditions and human health, and describes the transdisciplinary nature of the climate change adaptation research currently being adopted in Quebec, characterized by the three phases of problem identification, problem investigation, and problem transformation. A transdisciplinary approach is essential for dealing with complex ill-defined problems concerning human-environment interactions (for example, climate change), for allowing joint research, collective leadership, complex collaborations, and significant exchanges among scientists, decision makers, and knowledge users. Such an approach is widely supported in theory but has proved to be extremely difficult to implement in practice, and those who attempt it have met with heavy resistance, succeeding when they find the occasional opportunity within institutional or social contexts. In this paper we narrate the ongoing struggle involved in tackling the negative effects of climate change in multi-actor contexts at local and regional levels, a struggle that began in a quiet way in 1998. The paper will describe how public health adaptation research is supporting transdisciplinary action and implementation while also preparing for the future, and how this interaction to tackle a life-world problem (adaptation of the Quebec public health sector to climate change) in multi-actors contexts has progressively been established during the last 13 years. The first of the two sections introduces the social context of a Quebec undergoing climate changes. Current climatic conditions and expected changes will be described, and attendant health risks for the Quebec population. The second section addresses the scientific, institutional and normative dimensions of the problem. It corresponds to a "public health narrative" presented in three phases: (1) problem identification (1998-2002) beginning in northern Quebec; (2) problem investigation (2002-2006) in which

    As the existing sentiment analysis of public opinion on Internet cannot meet the demand for deep excavation of public opinion sentiment, we propose a topic sentiment analysis method based on PLSA. By this method, we extract the sub-topic of public opinion in different period with PLSA and build sentiment vocabularies. Considering the impact of modifiers and the contribution of the sentiment words to the sub-topic, we obtain every sub-topic sentiment orientation in different period as well as the whole topic sentiment evolution. Experiments show that this method cannot only describe the sentiment evolution of one sub-topic over time, but also describe the whole topic sentiment evolution with the change of sub-topic dimensions and content.%针对现有的关于网络舆情内容进行情感分析的研究不能满足舆情情感深度挖掘的需求,提出一种基于概率潜在语义分析( PLSA)的网络舆情话题情感分析方法,利用PLSA模型对不同时间段上的网络舆情话题进行子话题提取和情感词表构建,综合考虑修饰词对情感词的影响以及情感词对子话题的贡献程度,最终得到一个时间序列上各个子话题的情感倾向值以及整个话题的情感变化趋势。实验结果证明该方法不仅可以描述同一个子话题随时间的情感演化过程,还可以描述话题情感随子话题维度和内容的演变情况。

  10. Tracking topic birth and death in LDA.

    Energy Technology Data Exchange (ETDEWEB)

    Wilson, Andrew T.; Robinson, David Gerald

    2011-09-01

    Most topic modeling algorithms that address the evolution of documents over time use the same number of topics at all times. This obscures the common occurrence in the data where new subjects arise and old ones diminish or disappear entirely. We propose an algorithm to model the birth and death of topics within an LDA-like framework. The user selects an initial number of topics, after which new topics are created and retired without further supervision. Our approach also accommodates many of the acceleration and parallelization schemes developed in recent years for standard LDA. In recent years, topic modeling algorithms such as latent semantic analysis (LSA)[17], latent Dirichlet allocation (LDA)[10] and their descendants have offered a powerful way to explore and interrogate corpora far too large for any human to grasp without assistance. Using such algorithms we are able to search for similar documents, model and track the volume of topics over time, search for correlated topics or model them with a hierarchy. Most of these algorithms are intended for use with static corpora where the number of documents and the size of the vocabulary are known in advance. Moreover, almost all current topic modeling algorithms fix the number of topics as one of the input parameters and keep it fixed across the entire corpus. While this is appropriate for static corpora, it becomes a serious handicap when analyzing time-varying data sets where topics come and go as a matter of course. This is doubly true for online algorithms that may not have the option of revising earlier results in light of new data. To be sure, these algorithms will account for changing data one way or another, but without the ability to adapt to structural changes such as entirely new topics they may do so in counterintuitive ways.

    2007-12-01

    Full Text Available Although cross-disciplinary research collaboration is necessary to achieve a better understanding of how human and natural systems are dynamically linked, it often turns out to be very difficult in practice. We outline a framing approach to cross-disciplinary research that focuses on the different perspectives that researchers from different backgrounds use to make sense of the issues they want to research jointly. Based on interviews, participants’ evaluations, and our own observations during meetings, we analyze three aspects of frame diversity in a large-scale research project. First, we identify dimensions of difference in the way project members frame the central concept of adaptive water management. Second, we analyze the challenges provoked by the multiple framings of concepts. Third, we analyze how a number of interventions (interactive workshops, facilitation, group model building, and concrete case contexts contribute to the connection and integration of different frames through a process of joint learning and knowledge construction.

    This paper describes the interaction of four elements of social science as they have evolved in concert with the Center for Adaptive Optics Professional Development Program (CfAO PDP). We hope these examples persuade early-career scientists and engineers to include social science activities as they develop grant proposals and carry out their research. To frame our discussion we use a metaphor from astronomy. At the University of California Santa Cruz (UCSC), the CfAO PDP and the Educational Partnership Center (EPC) are two young stars in the process of forming a solar system. Together, they are surrounded by a disk of gas and dust made up of program evaluation, applied research, educational assessment, and pedagogy. An idea from the 2001 PDP intensive workshops program evaluation developed into the Assessing Scientific Inquiry and Leadership Skills (AScILS) applied research project. In iterative cycles, AScILS researchers participated in subsequent PDP intensive workshops, teaching social science while piloting AScILS measurement strategies. Subsequent "orbits" of the PDP program evaluation gathered ideas from the applied research and pedagogy. The denser regions of this disk of social science are in the process of forming new protoplanets as tools for research and teaching are developed. These tools include problem-solving exercises or simulations of adaptive optics explanations and scientific reasoning; rubrics to evaluate the scientific reasoning simulation responses, knowledge regarding inclusive science education, and student explanations of science/engineering inquiry investigations; and a scientific reasoning curriculum. Another applied research project is forming with the design of a study regarding how to assess engineering explanations. To illustrate the mutual shaping of the cross-disciplinary, intergenerational group of educational researchers and their projects, the paper ends with a description of the professional trajectories of some of the

    Full Text Available Abstract Background Community-based organizations (CBOs are important stakeholders in health systems and are increasingly called upon to use research evidence to inform their advocacy, program planning, and service delivery. To better support CBOs to find and use research evidence, we sought to assess the capacity of CBOs in the HIV/AIDS sector to acquire, assess, adapt, and apply research evidence in their work. Methods We invited executive directors of HIV/AIDS CBOs in Ontario, Canada (n = 51 to complete the Canadian Health Services Research Foundation's "Is Research Working for You?" survey. Findings Based on responses from 25 organizations that collectively provide services to approximately 32,000 clients per year with 290 full-time equivalent staff, we found organizational capacity to acquire, assess, adapt, and apply research evidence to be low. CBO strengths include supporting a culture that rewards flexibility and quality improvement, exchanging information within their organization, and ensuring that their decision-making processes have a place for research. However, CBO Executive Directors indicated that they lacked the skills, time, resources, incentives, and links with experts to acquire research, assess its quality and reliability, and summarize it in a user-friendly way. Conclusion Given the limited capacity to find and use research evidence, we recommend a capacity-building strategy for HIV/AIDS CBOs that focuses on providing the tools, resources, and skills needed to more consistently acquire, assess, adapt, and apply research evidence. Such a strategy may be appropriate in other sectors and jurisdictions as well given that CBO Executive Directors in the HIV/AIDS sector in Ontario report low capacity despite being in the enviable position of having stable government infrastructure in place to support them, benefiting from long-standing investment in capacity building, and being part of an active provincial network. CBOs in other

    2015-01-01

    Full Text Available This paper deals with the problems of “explosion of term,” uncertain parameter in static synchronous compensator (STATCOM system with nonlinear time-delay. An improved adaptive controller is proposed to enhance the transient stability of system states and reduce computational complexity of STATCOM control system. In contrast to backstepping control scheme in high order systems, the problem of “explosion of term” is avoided by designing dynamic surface controller. The low pass filter is included to allow a design where the model is not differentiated and thus has prevented the mathematical complexities effectively. In addition, unlike the traditional adaptive control schemes, the certainty equivalence principle is not required for estimating the uncertain parameter by system immersion and manifold invariant (I&I adaptive control. A smooth function is added to ensure that the estimation error converges to zero in finite time. The effectiveness of the proposed controller is verified by the simulations. Compared with adaptive backstepping and proportion integration differentiation (PID, the oscillation amplitudes of transient response are reduced by nearly half, and the time of reaching steady state is shortened by at least 11%.

    Metronidazole and azelaic acid are the only topical medications approved for rosacea. All other topical treatments for rosacea and its special forms are used off-label. Topical steroids are not indicated in rosacea, because of their side effects (induction of steroid rosacea, high risk of facial skin atrophy, and high risk of rebound after cessation of therapy). Topical as well as systemic steroids are allowed only as initial and short term therapy for acute forms of rosacea (e.g. rosacea fulminans). Papular and pustular rosacea is the major indication for topical therapy. Sebaceous gland and connective tissue hyperplasia in glandular-hypertrophic rosacea as well as erythema in erythematous rosacea do not respond well to topical measures. A new active substance, the alpha-2-adrenoreceptor agonist brimonidine, will be approved soon for the topical treatment of erythema in rosacea. All severe forms of rosacea should initially be treated with a combination of topical and systemic agents. After improvement of the clinical symptoms, topical treatment alone is usually adequate to maintain the control.

    2013-01-01

    Do scientists follow hot topics in their scientific investigations? In this paper, by performing analysis to papers published in the American Physical Society (APS) Physical Review journals, it is found that papers are more likely to be attracted by hot fields, where the hotness of a field is measured by the number of papers belonging to the field. This indicates that scientists generally do follow hot topics. However, there are qualitative differences among scientists from various countries, among research works regarding different number of authors, different number of affiliations and different number of references. These observations could be valuable for policy makers when deciding research funding and also for individual researchers when searching for scientific projects.

A transdisciplinary approach is essential for dealing with complex ill-defined problems concerning human–environment interactions (for example, climate change, for allowing joint research, collective leadership, complex collaborations, and significant exchanges among scientists, decision makers, and knowledge users. Such an approach is widely supported in theory but has proved to be extremely difficult to implement in practice, and those who attempt it have met with heavy resistance, succeeding when they find the occasional opportunity within institutional or social contexts. In this paper we narrate the ongoing struggle involved in tackling the negative effects of climate change in multi-actor contexts at local and regional levels, a struggle that began in a quiet way in 1998. The paper will describe how public health adaptation research is supporting transdisciplinary action and implementation while also preparing for the future, and how this interaction to tackle a life-world problem (adaptation of the Quebec public health sector to climate change in multi-actors contexts has progressively been

    2012-07-01

    Full Text Available At present, most aggregation routing algorithms for WSNs assume that aggregation expends are so little as to be neglected. But with the growing demand for the collection of multimedia data, the aggregation expends are much larger and can’t be neglect. In view of this problem, this paper proposes an adaptive aggregation routing algorithm with the minimal energy consumption (RMEAAT. Firstly, it constructs an -balancing spanning tree on the basis of SPT and MST as the initial communication path. And then it defines the aggregation benefit with consideration of aggregation expend and transmission expend, and data are adaptively judged whether to aggregate at every node of -balancing spanning tree according to aggregation benefit in the process of transmission. Correspondingly, the initial transmission path is gradually improved in terms of the aggregation judgment. The simulation results show that RMEAAT algorithm has better performance in WSNs with different aggregation expends and fusion degrees.

    Full Text Available The key problem of computer-aided diagnosis (CAD of lung cancer is to segment pathologically changed tissues fast and accurately. As pulmonary nodules are potential manifestation of lung cancer, we propose a fast and self-adaptive pulmonary nodules segmentation method based on a combination of FCM clustering and classification learning. The enhanced spatial function considers contributions to fuzzy membership from both the grayscale similarity between central pixels and single neighboring pixels and the spatial similarity between central pixels and neighborhood and improves effectively the convergence rate and self-adaptivity of the algorithm. Experimental results show that the proposed method can achieve more accurate segmentation of vascular adhesion, pleural adhesion, and ground glass opacity (GGO pulmonary nodules than other typical algorithms.

    In multimedia conference, the capability of audio processing is basic and requires more for real-time criteria. In this article, we categorize and analyze the schemes, and provide several multipoint speech audio mixing schemes using weighted algorithm, which meet the demand of practical needs for real-time multipoint speech mixing, for which the ASW and AEW schemes are especially recommended. Applying the adaptive algorithms, the high-performance schemes we provide do not use the saturation operation widely used in multimedia processing. Therefore, no additional noise will be added to the output. The above adaptive algorithms have relatively low computational complexity and good hearing perceptibility. The schemes are designed for parallel processing, and can be easily implemented with hardware, such as DSPs, and widely applied in multimedia conference systems.

    A robust adaptive trajectory linearization control (RATLC) algorithm for a class of nonlinear systems with uncertainty and disturbance based on the T-S fuzzy system is presented. The unknown disturbance and uncertainty are estimated by the T-S fuzzy system, and a robust adaptive control law is designed by the Lyapunov theory. Irrespective of whether the dimensions of the system and the rules of the fuzzy system are large or small, there is only one parameter adjusting on line. Uniformly ultimately boundedness of all signals of the composite closed-loop system are proved by theory analysis. Finally, a numerical example is studied based on the proposed method. The simulation results demonstrate the effectiveness and robustness of the control scheme.

    This paper proposes a corpus-based language model for topic identification. We analyze the association of noun-noun and noun-verb pairs in LOB Corpus. The word association norms are based on three factors: 1) word importance, 2) pair co-occurrence, and 3) distance. They are trained on the paragraph and sentence levels for noun-noun and noun-verb pairs, respectively. Under the topic coherence postulation, the nouns that have the strongest connectivities with the other nouns and verbs in the discourse form the preferred topic set. The collocational semantics then is used to identify the topics from paragraphs and to discuss the topic shift phenomenon among paragraphs.

  1. Research on the adaptation of skeletal muscle to hypogravity: Past and future directions

    Science.gov (United States)

    Riley, D. A.; Ellis, S.

    Our current understanding of hypogravity-induced atrophy of skeletal muscles is based primarily on studies comparing pre- and post-flight properties of muscles. Interpretations are necessarily qualified by the assumption that the stress of reentry and readjustment to terrestrial gravity do not alter the parameters being analyzed. The neuromuscular system is highly responsive to changes in functional demands and capable of rapid adaptation, making this assumption questionable. A reexamination of the changes in the connective tissue and synaptic terminals of soleus muscles from rats orbited in biosatellites and sampled postflight indicates that these structural alterations represent adaptative responses of the atrophic muscles to the increased workload of returning to 1 G, rather than hypogravity per se. The atrophy of weightlessness is postulated to result because muscles are both underloaded and used less often. Proper testing of this hypothesis requires quantitation of muscle function by monitoring electromyography, force output and length changes during the flight. Experiments conducted in space laboratories, like those being developed for the Space Shuttle, will avoid the complications of reentry before tissue sampling and allow time course studies of the rate of development of adaptive changes to zero gravity. Another area of great importance for future studies of muscle atrophy is inflight measurement of plasma levels of hormones and tissue receptor levels. Glucocorticoids, thyroid hormone and insulin exert dramatic regulatory influences on muscle structure. Prevention of neuromuscular atrophy becomes increasingly more important as spaceflights increase in duration. Definition of the atrophic mechanism is essential to developing means of preventing neuromuscular atrophy.

    Shimao, T

    2000-07-01

    I have engaged in the research on tuberculosis for 50 years, and lessons I have learnt during this period could be summarized in the following ten topics. First is great research achievements by our predecessors on the establishment of so-called primary infection theory on the pathogenesis of TB, planning of TB control principles based on the theory and development of new technologies used for TB control, such as mass miniature X-ray examination and BCG vaccination in 1920s and 1930s. TB control law was enforced in 1951, and the modern TB programme was initiated. Second, the field is a treasure house of interesting data. Several interesting data on TB soon after the World War II in Tokyo and a rural area were collected and analyzed from the mass health examination. Third, looking at the increase of tuberculin positivity with age, it was found that the tuberculin negativity decreased as the exponential function of age, and the current concept of the annual risk of TB infection was already developed in late 1940s. It was 18.1% in male and 11.6% in female in Tokyo in late 1940s. Based on this concept, age specific TB mortality was analyzed by the type of TB, and the rates of miliary TB and TB meningitis were similar to the rate of newly infected to the total population, while the rate of all forms could be divided into early and late death as shown in Fig. 1. Fourth, I suffered from TB by myself from 1951 to 1953, receiving first thoracoplasty in two stages under local anaesthesia, then right upper lobectomy and segmentectomy of superior segment of right lower lobe. From this experience, I learnt a lot about the psychology and suffering of TB patients. Fifth, the importance of recognition of real magnitude of the problem in such a disease as TB in which many TB cases did not aware of their disease. The answer to this was the first TB prevalence survey in 1953 using stratified random sampling method, and based on the results of the survey, the mass health examination

    2014-01-01

    Full Text Available Energy management control strategy of hybrid electric vehicle has a great influence on the vehicle fuel consumption with electric motors adding to the traditional vehicle power system. As vehicle real driving cycles seem to be uncertain, the dynamic driving cycles will have an impact on control strategy’s energy-saving effect. In order to better adapt the dynamic driving cycles, control strategy should have the ability to recognize the real-time driving cycle and adaptively adjust to the corresponding off-line optimal control parameters. In this paper, four types of representative driving cycles are constructed based on the actual vehicle operating data, and a fuzzy driving cycle recognition algorithm is proposed for online recognizing the type of actual driving cycle. Then, based on the equivalent fuel consumption minimization strategy, an ant colony optimization algorithm is utilized to search the optimal control parameters “charge and discharge equivalent factors” for each type of representative driving cycle. At last, the simulation experiments are conducted to verify the accuracy of the proposed fuzzy recognition algorithm and the validity of the designed control strategy optimization method.

    2002-10-01

    This article examines a partnership between researchers from the United States who are involved in corrections health issues and scientists from South Africa who conduct prison health research, a previously underresearched area in South Africa. The article discusses some of the challenges as well as opportunities for knowledge and skills exchange via capacity building and collaboration strategies. Through historical and contemporary perspectives, it also discusses barriers and benefits of collaboration when forging links between researchers from developed and less developed nations. A focus on conducting public health research in South Africa, and on HIV/AIDS studies in particular, is placed within the context of the 2001 document of the Council on Health Research for Development. The South African prison health study represents a collaborative between the South African National Health Promotion Research and Development Group of the Medical Research Council, the South African Department of Correctional Services, and Emory University in Atlanta, Georgia. The article illuminates the process of adapting a model for a postapartheid prison study from one designed for use in the American correctional system. PMID:12413197

    2009-01-01

    Full Text Available Melasma is a common hypermelanotic disorder affecting the face that is associated with considerable psychological impacts. The management of melasma is challenging and requires a long-term treatment plan. In addition to avoidance of aggravating factors like oral pills and ultraviolet exposure, topical therapy has remained the mainstay of treatment. Multiple options for topical treatment are available, of which hydroquinone (HQ is the most commonly prescribed agent. Besides HQ, other topical agents for which varying degrees of evidence for clinical efficacy exist include azelaic acid, kojic acid, retinoids, topical steroids, glycolic acid, mequinol, and arbutin. Topical medications modify various stages of melanogenesis, the most common mode of action being inhibition of the enzyme, tyrosinase. Combination therapy is the preferred mode of treatment for the synergism and reduction of untoward effects. The most popular combination consists of HQ, a topical steroid, and retinoic acid. Prolonged HQ usage may lead to untoward effects like depigmentation and exogenous ochronosis. The search for safer alternatives has given rise to the development of many newer agents, several of them from natural sources. Well-designed controlled clinical trials are needed to clarify their role in the routine management of melasma.

    2011-01-01

    This paper presents a public health narrative on Quebec's new climatic conditions and human health, and describes the transdisciplinary nature of the climate change adaptation research currently being adopted in Quebec, characterized by the three phases of problem identification, problem investigation, and problem transformation. A transdisciplinary approach is essential for dealing with complex ill-defined problems concerning human-environment interactions (for example, climate change), for allowing joint research, collective leadership, complex collaborations, and significant exchanges among scientists, decision makers, and knowledge users. Such an approach is widely supported in theory but has proved to be extremely difficult to implement in practice, and those who attempt it have met with heavy resistance, succeeding when they find the occasional opportunity within institutional or social contexts. In this paper we narrate the ongoing struggle involved in tackling the negative effects of climate change in multi-actor contexts at local and regional levels, a struggle that began in a quiet way in 1998. The paper will describe how public health adaptation research is supporting transdisciplinary action and implementation while also preparing for the future, and how this interaction to tackle a life-world problem (adaptation of the Quebec public health sector to climate change) in multi-actors contexts has progressively been established during the last 13 years. The first of the two sections introduces the social context of a Quebec undergoing climate changes. Current climatic conditions and expected changes will be described, and attendant health risks for the Quebec population. The second section addresses the scientific, institutional and normative dimensions of the problem. It corresponds to a "public health narrative" presented in three phases: (1) problem identification (1998-2002) beginning in northern Quebec; (2) problem investigation (2002-2006) in which

    Full Text Available Abstract Background Molluscum contagiosum is a non-severe pediatric viral infection. Because it is highly contagious and current treatments have negative aesthetic and psychological effects, we want to test an alternative treatment in the primary care setting, consisting of two different concentrations of potassium hydroxide solution. Methods/design The study design is a double-blind, randomized clinical trial, using three types of topical treatment. The treatment consist of daily applications of potassium hydroxide (KOH in aqueous solution at 10% and 15% concentration, and a placebo administered in the control group. Four follow-up visits (at 15, 30, 45 and 60 days are planned to evaluate treatment effectiveness and patient tolerance. The main outcome measure of the trial will be the healing rate, defined as lesion disappearance in the affected zones after the topic application of the experimental treatment. Secondary measures will be the principal characteristics and evolution of the affected zone (surface area, number of lesions, size and density of lesions, treatment tolerance (hyperpigmentation, itching, burning, pain, recurrence rate and the natural evolution of lesions in the control group. Discussion KOH can potentially be an effective and safe treatment for MC in primary care, and can also reduce referrals to dermatologists and hospital pediatric departments. In addition, KOH may be a valid and less expensive alternative to current invasive treatments (surgical excision. Trial Registration ClinicalTrials.gov: NCT01348386

We show that a certain number of nominal inversion cases in French, a syntactic configuration which is triggered by the presence of an explicit stage topic, are explained by the presence of an implicit stage topic. The fact that implicit stage topics interact with syntactic structure the same way explicit stage topics do constitutes a strong empirical argument in favour of their existence.

    Consumer research on advertising response has gradually separated the act of reading an ad from the acquisition of brand information. Because the advertising text is the pathway through which brand information is accessed, current models truncate the process that leads to response in a way that distorts our view of both advertising and the mind that reads it. This author proposes that reader-response theory would help researchers study the process of reading as an essential link between adver...

  16. The significance of 'hierarchy' in a research project on adoption and adaptation.

    Mander, R

    1999-06-01

    In the course of phenomenological research project focusing on the midwife's care of the mother who relinquishes her baby for adoption, hierarchy emerged repeatedly as a significant theme. This concept manifested itself both methodologically as well as thematically. In methodological terms, hierarchy first became apparent during the planning phase in the selection of the research design: at this point it took the form of the distinction between quantitative and qualitative research design. In the course of applying for research access the same attitudes re-emerged in the gatekeepers' responses to the research design which had been chose. Later, during the field work, hierarchy appeared in the course of the interviews, in the form of the unequal balance of power between the interviewer and the informant. Specific tactics were required to overcome the likelihood of hierarchy affecting the data at this stage. Eventually this concept was raised by the informants, who included both relinquishing mothers an midwives, and became a major theme. The informants' use of hierarchy to explain the unselfishness of relinquishment proved to be one of a number of strategies which facilitated coping either with the experience of relinquishment or with caring for a women going through that experience. The conclusion which emerges is that hierarchy features in many aspects of life. While it may be beneficial when applied to certain situations to facilitate coping, in other circumstances it may be less than positive. PMID:10703416

    There are some types of complex systems that are built like clockwork, with well-defined parts that interact in well-defined ways, so that the action of the whole can be precisely analyzed and anticipated with accuracy and precision. Some systems are not themselves so well-defined, but they can be modeled in ways that are like trained pilots in well-built planes, or electrolyte balance in healthy humans. But there are many systems for which that is not true; and among them are many whose understanding and control we would value. For example, the model for the trained pilot above fails exactly where the pilot is being most human; that is, where he is exercising the highest levels of judgment, or where he is learning and adapting to new conditions. Again, sometimes the kinds of complexity do not lead to easily analyzable models at all; here we might include most economic systems, in all forms of societies. There are several factors that seem to contribute to systems being hard to model, understand, or control. ...

  5. From ships in the night to exchanges in the piazza: Renegotiating the researcher-stakeholder nexus in climate adaptation

    Science.gov (United States)

    Jackson, S. T.

    2015-12-01

    A substantial divide remains between the communities of research, embedded largely in universities and science agencies, and the communities of practice, comprising the natural-resource managers and other decision-makers in diverse federal, state, local, and tribal agencies and in private-sector enterprises and organizations. In spite of clear needs and best intentions, engagement among the respective communities is imperfect; researchers and stakeholders are often like ships passing in the night, exchanging brief, cryptic signals. A variety of boundary organizations have been developed to facilitate the communications, and a number of successful models for researcher-stakeholder exchange and engagement have been applied. At least two substantial challenges remain. First, how can the successes be scaled up and proliferated to meet the vast demands posed by climate adaptation? Second, how can the various boundary organizations most effectively foster this expansion, individually and collectively? Meeting these challenges will require coordination among the respective organizations, changes in the cultures of research and management, and careful assessment of process and outcomes.

  6. Topical ketoprofen patch.

    Mazières, Bernard

    2005-01-01

    Although oral nonsteroidal anti-inflammatory drugs (NSAIDs) are effective in the treatment of a variety of acute and chronic pain conditions, their use may be associated with serious systemic adverse effects, particularly gastrointestinal disorders. In order to minimise the incidence of systemic events related to such agents, topical NSAIDs have been developed. Topical NSAIDs, applied as gels, creams or sprays, penetrate the skin, subcutaneous fatty tissue and muscle in amounts that are sufficient to exert a therapeutic effect on peripheral and central mechanisms in the absence of high plasma concentrations. Data indicate that topical NSAIDs are effective at relieving pain in a number of acute and chronic pain indications. This review article discusses the pharmacokinetics, efficacy and tolerability of a new formulation of ketoprofen available as a topical patch. The topical patch containing ketoprofen 100mg as the active principle has been developed using a novel delivery system that dispenses therapeutic doses of the drug directly to the site of injury. Pharmacokinetic data indicate that although plasma levels of ketoprofen are higher when the drug is administered as a patch versus a gel, the total systemic bioavailability of ketoprofen 100 mg administered via a patch is no more than 10% of that reported for ketoprofen 100 mg administered orally. Because the patch facilitates ketoprofen delivery over a 24-hour period, the drug remains continually present in the tissue subjacent to the site of application. High tissue but low plasma ketoprofen concentrations mean that while tissue concentrations are high enough to exert a therapeutic effect, plasma concentrations remain low enough to not result in systemic adverse events caused by elevated serum NSAID levels. Phase III clinical trials in patients with non-articular rheumatism and traumatic painful soft tissue injuries showed that the topical ketoprofen patch was significantly more effective than placebo at

    This title adopts the view that physics is the primary driving force behind a number of developments in mathematics. Previously, science and mathematics were part of natural philosophy and many mathematical theories arose as a result of trying to understand natural phenomena. This situation changed at the beginning of last century as science and mathematics diverged. These two fields are collaborating once again; 'Topics in Mathematical Physics' takes the reader through this journey. The author discusses topics where the interaction of physical and mathematical theories has led to new points o

    Traditional supervised learning algorithms assume that the training data and the test data are drawn from the same probability distribution. But in many cases, this assumption is too simplified, and too harsh in light of modern applications of machine learning. Domain adaptation approaches are used to solve the problem that arises when the data distribution in the test domain is different from that in the training domain. Although the domain adaptation problem is a fundamental problem in machine learning, it only started gaining much attention very recently. In view of the theoretical and practical significance of domain adaptation methods, this paper summarizes the learning algorithm for domain adaptation. Firstly, the basic issues of domain adaptation and several important methods on domain adaptation are summarizes. Next, learning theory and hot research direction on domain adaptation are described, including instance weighting based method, feature representation based method, parameter and feature decomposition based method, domain adaptation with multiple sources. Thirdly, the theoretical analysis for domain adaptation and the effective distribution metric learning are illustrated. At the same time, the error bounds of those algorithms are also presented. Fourthly, new research and development in three aspects on domain adaptation in recent years are reviewed, including learning algorithm, model structure and practical application. Finally, the problems to be solved in aspects of feature transform and assumption, optimization algorithm, data representation and model, and the problem to be solved in NLP are discussed.%传统的机器学习假设测试样本和训练样本来自同一概率分布。但当前很多学习场景下训练样本和测试样本可能来自不同的概率分布。域自适应学习能够有效地解决训练样本和测试样本概率分布不一致的学习问题,作为机器学习新出现的研究领域在近几年受到了广

    This report synthesizes the knowledge, opinions, and concerns of many Federal and State land managers, scientists, stakeholders, and partners from a workshop, held at the University of Nevada, Las Vegas, on April 20-22, 2010. Land managers, research scientists, and resource specialists identified common concerns regarding the potential effects of climate change on public lands and natural resources in the Great Basin and Mojave Desert and developed recommendations for mitigation, adaptation, and research needs. Water and, conversely, the effects of drought emerged as a common theme in all breakout sessions on terrestrial and aquatic species at risk, managing across boundaries, monitoring, and ecosystem services. Climate change models for the southwestern deserts predict general warming and drying with increasing precipitation variability year to year. Scientists noted that under these changing conditions the past may no longer be a guide to the future in which managers envision increasing conflicts between human water uses and sustaining ecosystems. Increasing environmental stress also is expected as a consequence of shifting ecosystem boundaries and species distributions, expansion of non-native species, and decoupling of biotic mutualisms, leading to increasingly unstable biologic communities. Managers uniformly expressed a desire to work across management and agency boundaries at a landscape scale but conceded that conflicting agency missions and budgetary constraints often impede collaboration. More and better science is needed to cope with the effects of climate change but, perhaps even more important is the application of science to management issues using the methods of adaptive management based on long-term monitoring to assess the merits of management actions. Access to data is essential for science-based land management. Basic inventories, spatial databases, baseline condition assessments, data quality assurance, and data sharing were identified as top

    2009-07-01

    Full Text Available Abstract Background The SRS-22 is a valid instrument for the assessment of the health related quality of life of patients with Idiopathic scoliosis. The SRS-22 questionnaire was developed in USA and has been widely used in the English speaking countries. Recently it has been translated and validated in many other languages. The purpose of this study is to evaluate the reliability and validity of the adapted Greek version of the refined Scoliosis Research Society-22 Questionnaire. Methods Following the steps of cross – cultural adaptation the adapted Greek version of the SRS-22 questionnaire and a validated Greek version of the SF-36 questionnaire were mailed to 68 patients treated surgically for Idiopathic Scoliosis. 51 out of the 68 patients returned the 1st set of questionnaires, while a second set was emailed to 30 randomly selected patients of the first time responders. 20 out of the 30 patients returned the 2nd set. The mean age at the time of operation was16,2 years and the mean age at the time of evaluation was 21,2 years. Descriptive statistics for content analysis were calculated. Reliability assessment was determined by estimating Cronbach's α and intraclass correlation coefficient (ICC respectively. Concurrent validity was evaluated by comparing SRS-22 domains with relevant domains in the SF-36 questionnaire using Pearson's Correlation Coefficient (r. Results The calculated Cronbach's α of internal consistency for three of the corresponding domains (pain 0.85; mental health 0.87; self image 0.83 were very satisfactory and for two domains (function/activity 0.72 and satisfaction 0.67 were good. The ICC of all domains of SRS-22 questionnaire was high (ICC>0.70, demonstrating very satisfactory or excellent test/retest reproducibility. Considering concurrent validity all correlations were found to be statistically significant at the 0.01 level among related domains and generally demonstrated high correlation coefficient.

    In applications we may want to compare different document collections: they could have shared content but also different and unique aspects in particular collections. This task has been called comparative text mining or cross-collection modeling. We present a differential topic model for this application that models both topic differences and similarities. For this we use hierarchical Bayesian nonparametric models. Moreover, we found it was important to properly model power-law phenomena in topic-word distributions and thus we used the full Pitman-Yor process rather than just a Dirichlet process. Furthermore, we propose the transformed Pitman-Yor process (TPYP) to incorporate prior knowledge such as vocabulary variations in different collections into the model. To deal with the non-conjugate issue between model prior and likelihood in the TPYP, we thus propose an efficient sampling algorithm using a data augmentation technique based on the multinomial theorem. Experimental results show the model discovers interesting aspects of different collections. We also show the proposed MCMC based algorithm achieves a dramatically reduced test perplexity compared to some existing topic models. Finally, we show our model outperforms the state-of-the-art for document classification/ideology prediction on a number of text collections. PMID:26353238

  20. Contrastive topics decomposed

    Directory of Open Access Journals (Sweden)

    Michael Wagner

    2012-12-01

    Full Text Available The analysis of contrastive topics introduced in Büring 1997b and further developed in Büring 2003 relies on distinguishing two types of constituents that introduce alternatives: the sentence focus, which is marked by a FOC feature, and the contrastive topic, which is marked by a CT feature. A non-compositional rule of interpretation that refers to these features is used to derive a topic semantic value, a nested set of sets of propositions. This paper presents evidence for a correlation between the restrictive syntax of nested focus operators and the syntax of contrastive topics, a correlation which is unexpected under this analysis. A compositional analysis is proposed that only makes use of the flatter focus semantic values introduced by focus operators. The analysis aims at integrating insights from the original analysis while at the same time capturing the observed syntactic restrictions. http://dx.doi.org/10.3765/sp.5.8 BibTeX info

    Full Text Available Pictorial stimuli and words have been widely used to evaluate mnemonic processes in clinical settings, neuropsychological investigations, as well as in studies on the mechanisms underlying the phenomena of memory. However, there seem to be few studies of standardisation of pictures for research in this field. The present paper aimed at adapting the use of a set of pictures standardised for English speaking subjects for Portuguese speakers. Name agreement of 150 pictures was assessed in 100 high-school students. Ninety pictures were found to present the same name for over 90 subjects. Results yield data that may help create more controlled tests for the study of memory for pictorial stimuli in Brazil.

    2009-01-01

    Grey relational analysis is an important part of the grey systems theory, and it is the basis of the grey clustering analysis, grey decision-making and grey controlling. To research whether grey relational models satisfy the four grey relational theorems, several kinds of grey relational models are commented. Some problems including the properties of normality, pair symmetry and wholeness are discussed. The phenomenon that the lower value of almost each grey relational model is not equal to zero is proved. The contradiction problems between the properties of wholeness and pair symmetry are verified. Finally, several propositions are constructed to explain the above problems.

    2016-04-01

    Full Text Available Trying to make sense and gain deeper insight from large sets of data is becoming a task very central to computer science in general. Topic models, capable of uncovering the semantic themes pervading through large collections of documents, have seen a surge in popularity in recent years. However, topic models are high level statistical tools; their output is given in terms of probability distributions, suited neither for simple interpretation nor deep analysis. Interpreting the fitted topic models in an intuitive manner requires visual and interactive tools. Additionally, some measure of human interaction is typically required for refining the output offered by such models. In the research, this area remains relatively unexplored – only recently has this aspect been receiving more attention. In this paper, the literature is surveyed as it pertains to interactivity and visualisation within the context of topic models, with the goal of finding current research trends in this area.

    Topical retinoids are currently approved by the US Food and Drug Administration for the treatment of acne vulgaris in nonpregnant, nonlactating patients 12 years of age and older. Their efficacy, safety, and tolerability are well documented for inflammatory and noninflammatory acne with studies repeatedly demonstrating a decrease in the number of lesions, significant improvement in acne severity, improvement in the cosmetic appearance of acne, and the prevention of acne lesions through microcomedone formation. There is some variability between prescription retinoid products regarding efficacy, safety, and tolerability; with erythema, peeling, and dryness being common, potential side effects. Due to their efficacious and safe profile, topical retinoids remain the first-line treatment for acne vulgaris. PMID:27416308

    基于文本关系图摘要是当下多主题文本摘要中常用方法,针对该方法的不足,对其进行了改进。首先,由于基于词频统计的文本相似度计算方法对句子作用有限,引入依存句法分析,通过挖掘语义信息来扩展句子特征项,提高句子相似度计算准确性。其次,选择基于图结构的无尺度图K-中心点聚类算法对文本关系图进行聚类分析,提高主题挖掘的准确性。最后,综合考虑句子相似度和位置信息来计算句子权重,提高摘要句抽取的准确性。最后用实验证明该改进方法的有效性。%Summarization based on text relationship map is often used in the multiple topics document summary. The defects of this meth-od are improved in this paper. Firstly, because the text similarity computing method based on word frequency statistics is limited to sen-tence, this paper introduces the dependency parsing. We extend sentences feature items by mining the semantic information to improve the accuracy of sentence similarity computing. Secondly, this paper selects the scale-free graph clustering algorithm based on graph structure for clustering analysis to improve the accuracy of the theme mining. Then, this paper calculates the weight of the sentence by considering the sentence similarity and location information to improve the accuracy of summary sentence extraction. Finally, the effectiveness of this improved method is proved by experiments.

  18. Practical considerations for adaptive trial design and implementation

    CERN Document Server

    Pinheiro, José; Kuznetsova, Olga

    2014-01-01

    This edited volume is a definitive text on adaptive clinical trial designs from creation and customization to utilization. As this book covers the full spectrum of topics involved in the adaptive designs arena, it will serve as a valuable reference for researchers working in industry, government and academia. The target audience is anyone involved in the planning and execution of clinical trials, in particular, statisticians, clinicians, pharmacometricians, clinical operation specialists, drug supply managers, and infrastructure providers.  In spite of the increased efficiency of adaptive trials in saving costs and time, ultimately getting drugs to patients sooner, their adoption in clinical development is still relatively low.  One of the chief reasons is the higher complexity of adaptive design trials as compared to traditional trials. Barriers to the use of clinical trials with adaptive features include the concerns about the integrity of study design and conduct, the risk of regulatory non-acceptance, t...

  19. Topics in Banach space theory

    CERN Document Server

    Albiac, Fernando

    2016-01-01

    This text provides the reader with the necessary technical tools and background to reach the frontiers of research without the introduction of too many extraneous concepts. Detailed and accessible proofs are included, as are a variety of exercises and problems. The two new chapters in this second edition are devoted to two topics of much current interest amongst functional analysts: Greedy approximation with respect to bases in Banach spaces and nonlinear geometry of Banach spaces. This new material is intended to present these two directions of research for their intrinsic importance within Banach space theory, and to motivate graduate students interested in learning more about them. This textbook assumes only a basic knowledge of functional analysis, giving the reader a self-contained overview of the ideas and techniques in the development of modern Banach space theory. Special emphasis is placed on the study of the classical Lebesgue spaces Lp (and their sequence space analogues) and spaces of continuous f...

  20. Synergetics introduction and advanced topics

    CERN Document Server

    Haken, Hermann

    2004-01-01

    This book is an often-requested reprint of two classic texts by H. Haken: "Synergetics. An Introduction" and "Advanced Synergetics". Synergetics, an interdisciplinary research program initiated by H. Haken in 1969, deals with the systematic and methodological approach to the rapidly growing field of complexity. Going well beyond qualitative analogies between complex systems in fields as diverse as physics, chemistry, biology, sociology and economics, Synergetics uses tools from theoretical physics and mathematics to construct an unifying framework within which quantitative descriptions of complex, self-organizing systems can be made. This may well explain the timelessness of H. Haken's original texts on this topic, which are now recognized as landmarks in the field of complex systems. They provide both the beginning graduate student and the seasoned researcher with solid knowledge of the basic concepts and mathematical tools. Moreover, they admirably convey the spirit of the pioneering work by the founder of ...

  1. Innovative and adaptive technologies in decommissioning of nuclear facilities. Final report of a coordinated research project 2004-2008

    International Nuclear Information System (INIS)

    There are dozens of old reactors and other nuclear facilities worldwide that are either being actively dismantled or are candidates for decommissioning in the near term. A significant proportion of these facilities are situated in Member States or institutions that do not have adequate expertise and technologies for planning and implementing state of the art decommissioning projects. The technology selection process is critical in that regard. The main objective of the IAEA technical activities on decommissioning is to promote the exchange of lessons learned in order to improve the technologies, thereby contributing to successful planning and implementation of decommissioning. This should be achieved through a better understanding of the decision making process in technology comparison and selection and relevant issues affecting the entire decommissioning process. The specific objectives of the Coordinated Research Project (CRP) on Innovative and Adaptive Technologies in Decommissioning of Nuclear Facilities include the following general aspects: (a) To establish methodologies and data needs for developing concepts and approaches relevant to technology comparison and selection in decommissioning; (b) To improve and expand the database on applications and performance of various types of decommissioning technologies; (c) To address specific issues for individual decommissioning technologies and generate data relevant to their comparison and selection. It is also expected that this project, and in particular the papers collected in this TECDOC, will draw Member States' attention to the practicality and achievability of timely planning and implementation of decommissioning, especially for many smaller projects. Concluding reports that summarized the work undertaken under the aegis of the CRP were presented at the third and final research coordination meeting held in Rez, Czech Republic, 3-7 December 2007, and collected in this technical publication.

  2. A research needs assessment for the capture, utilization and disposal of carbon dioxide from fossil fuel-fired power plants. Volume 2, Topical reports: Final report

    Energy Technology Data Exchange (ETDEWEB)

    1993-07-01

    This study, identifies and assesses system approaches in order to prioritize research needs for the capture and non-atmospheric sequestering of a significant portion of the carbon dioxide (CO{sub 2}) emitted from fossil fuel-fired electric power plants (US power plants presently produce about 7% of the world`s CO{sub 2} emissions). The study considers capture technologies applicable either to existing plants or to those that optimistically might be demonstrated on a commercial scale over the next twenty years. The research needs that have high priority in establishing the technical, environmental, and economic feasibility of large-scale capture and disposal of CO{sub 2} from electric power plants are:(1) survey and assess the capacity, cost, and location of potential depleted gas and oil wells that are suitable CO{sub 2} repositories (with the cooperation of the oil and gas industry); (2) conduct research on the feasibility of ocean disposal, with objectives of determining the cost, residence time, and environmental effects for different methods of CO{sub 2} injection; (3) perform an in-depth survey of knowledge concerning the feasibility of using deep, confined aquifers for disposal and, if feasible, identify potential disposal locations (with the cooperation of the oil and gas industry); (4) evaluate, on a common basis, system and design alternatives for integration of CO{sub 2} capture systems with emerging and advanced technologies for power generation; and prepare a conceptual design, an analysis of barrier issues, and a preliminary cost estimate for pipeline networks necessary to transport a significant portion of the CO{sub 2} to potentially feasible disposal locations.

  10. The use of fiber Bragg grating sensors in biomechanics and rehabilitation applications: the state-of-the-art and ongoing research topics.

    Science.gov (United States)

    Al-Fakih, Ebrahim; Abu Osman, Noor Azuan; Mahamd Adikan, Faisal Rafiq

    2012-01-01

    In recent years, fiber Bragg gratings (FBGs) are becoming increasingly attractive for sensing applications in biomechanics and rehabilitation engineering due to their advantageous properties like small size, light weight, biocompatibility, chemical inertness, multiplexing capability and immunity to electromagnetic interference (EMI). They also offer a high-performance alternative to conventional technologies, either for measuring a variety of physical parameters or for performing high-sensitivity biochemical analysis. FBG-based sensors demonstrated their feasibility for specific sensing applications in aeronautic, automotive, civil engineering structure monitoring and undersea oil exploration; however, their use in the field of biomechanics and rehabilitation applications is very recent and its practicality for full-scale implementation has not yet been fully established. They could be used for detecting strain in bones, pressure mapping in orthopaedic joints, stresses in intervertebral discs, chest wall deformation, pressure distribution in Human Machine Interfaces (HMIs), forces induced by tendons and ligaments, angles between body segments during gait, and many others in dental biomechanics. This article aims to provide a comprehensive overview of all the possible applications of FBG sensing technology in biomechanics and rehabilitation and the status of ongoing researches up-to-date all over the world, demonstrating the FBG advances over other existing technologies.

  11. Wilsonville Advanced Coal Liquefaction Research and Development Facility, Wilsonville, Alabama. Topical report No. 14. Catalyst activity trends in two-stage coal liquefaction

    Energy Technology Data Exchange (ETDEWEB)

    1984-02-01

    The Two Stage Coal Liquefaction process became operational at Wilsonville in May 1981, with the inclusion of an H-OIL ebullated-bed catalytic reactor. The two stage process was initially operated in a nonintegrated mode and has recently been reconfigurated to fully integrate the thermal and the catalytic stages. This report focuses on catalyst activity trends observed in both modes of operation. A literature review of relevant catalyst screening studies in bench-scale and PDU units is presented. Existing kinetic and deactivation models were used to analyze process data over an extensive data base. Based on the analysis, three separate, application studies have been conducted. The first study seeks to elucidate the dependence of catalyst deactivation rate on type of coal feedstock used. A second study focuses on the significance of catalyst type and integration mode on SRC hydrotreatment. The third study presents characteristic deactivation trends observed in integrated operation with different first-stage thermal severities. In-depth analytical work was conducted at different research laboratories on aged catalyst samples from Run 242. Model hydrogenation and denitrogenation activity trends are compared with process activity trends and with changes observed in catalyst porosimetric properties. The accumulation of metals and coke deposits with increasing catalyst age, as well as their distribution across a pellet cross-section, are discussed. The effect of catalyst age and reactor temperature on the chemical composition of flashed bottoms product is addressed. Results from regenerating spent catalysts are also presented. 35 references, 31 figures, 18 tables.

    International Nuclear Information System (INIS)

    The growth of the Internet has provided a unique opportunity to expand research collaborations between industry, universities, and the national laboratories. The Virtual Robotics Laboratory (VRL) is an innovative program at Oak Ridge National Laboratory (ORNL) that is focusing on the issues related to collaborative research through controlled access of laboratory equipment using the World Wide Web. The VRL will provide different levels of access to selected ORNL laboratory secondary education programs. In the past, the ORNL Robotics and Process Systems Division has developed state-of-the-art robotic systems for the Army, NASA, Department of Energy, Department of Defense, as well as many other clients. After proof of concept, many of these systems sit dormant in the laboratories. This is not out of completion of all possible research topics. but from completion of contracts and generation of new programs. In the past, a number of visiting professors have used this equipment for their own research. However, this requires that the professor, and possibly his/her students, spend extended periods at the laboratory facility. In addition, only a very exclusive group of faculty can gain access to the laboratory and hardware. The VRL is a tool that enables extended collaborative efforts without regard to geographic limitations

  16. A Many-Objective Approach to Developing Adaptive Water Supply Portfolios in the 'Research Triangle' Region of North Carolina

    Science.gov (United States)

    Zeff, H. B.; Kasprzyk, J. R.; Reed, P. M.; Characklis, G. W.

    2012-12-01

    This study uses many-objective evolutionary optimization to quantify the tradeoffs water utilities face when developing flexible water shortage response plans. Alternatives to infrastructure development, such as temporary demand management programs and inter-utility water transfer agreements, allow local water providers to develop portfolios of water supply options capable of adapting to changing hydrologic conditions and growing water demand. The extent to which these options are implemented will be determined by a number of conflicting operational and financial considerations. An integrated reservoir simulation model including four large water utilities in the 'Research Triangle' region of North Carolina is used to evaluate the potential tradeoffs resulting from regional demands on shared infrastructure, customer concerns, and the financial uncertainty caused by the intermittent and irregular nature of drought. Instead of providing one optimal solution, multi-objective evolutionary algorithms (MOEAs) use the concept of non-dominations to discover a set of portfolio options in which no solution is inferior to any other solution in all objectives. Interactive visual analytics enable water providers to explore these tradeoffs and develop water shortage response plans tailored to their individual circumstances. The simulation model is evaluated under a number of different formulations to help identify and visualize the impacts of water efficiency, revenue/cost variability, consumer effects, and inter-utility cooperation. The different problems are formulated by adding portfolio options and objectives in such a way that the lower dimensional problem formulations are sub-sets of the full formulation. The full formulation considers reservoir reliability, water use restriction frequency, total water transfer allotment, total costs, revenue/cost variability, and additional consumer losses during restrictions. The simulation results highlight the inadequacy of lower order

    2015-06-30

    Reduced-order models provide a means for greatly accelerating the detailed simulations that will be required to manage CO2 storage operations. In this work, we investigate the use of one such method, POD-TPWL, which has previously been shown to be effective in oil reservoir simulation problems. This method combines trajectory piecewise linearization (TPWL), in which the solution to a new (test) problem is represented through a linearization around the solution to a previously-simulated (training) problem, with proper orthogonal decomposition (POD), which enables solution states to be expressed in terms of a relatively small number of parameters. We describe the application of POD-TPWL for CO2-water systems simulated using a compositional procedure. Stanford’s Automatic Differentiation-based General Purpose Research Simulator (AD-GPRS) performs the full-order training simulations and provides the output (derivative matrices and system states) required by the POD-TPWL method. A new POD-TPWL capability introduced in this work is the use of horizontal injection wells that operate under rate (rather than bottom-hole pressure) control. Simulation results are presented for CO2 injection into a synthetic aquifer and into a simplified model of the Mount Simon formation. Test cases involve the use of time-varying well controls that differ from those used in training runs. Results of reasonable accuracy are consistently achieved for relevant well quantities. Runtime speedups of around a factor of 370 relative to full- order AD-GPRS simulations are achieved, though the preprocessing needed for POD-TPWL model construction corresponds to the computational requirements for about 2.3 full-order simulation runs. A preliminary treatment for POD-TPWL modeling in which test cases differ from training runs in terms of geological parameters (rather than well controls) is also presented. Results in this case involve only small differences between

    Full Text Available Christos E Lampropoulos, David P D’CruzLupus Research Unit, Rayne Institute, St. Thomas’ Hospital, London, UKAbstract: Cutaneous lupus erythematosus (CLE encompasses a variety of lesions that may be refractory to systemic or topical agents. Discoid lupus erythematosus (DLE and subacute cutaneous lupus erythematosus (SCLE are the most common lesions in clinical practice. The topical calcineurin inhibitors, tacrolimus and pimecrolimus, have been used to treat resistant cutaneous lupus since 2002 and inhibit the proliferation and activation of T-cells and suppress immune-mediated cutaneous inflammation. This article reviews the mechanism of action, efficacy, adverse effects, and the recent concern about their possible carcinogenic effect. Although the total number of patients is small and there is only one relevant randomized controlled study, the data are encouraging. Many patients, previously resistant to systemic agents or topical steroids, improved after four weeks of treatment. DLE and SCLE lesions were less responsive, reflecting the chronicity of the lesions, although more than 50% of patients still showed improvement. Topical calcineurin inhibitors may be a safe and effective alternative to topical steroids for CLE although the only approved indication is for atopic dermatitis.Keywords: tacrolimus, pimecrolimus, cutaneous lupus erythematosus, topical calcineurin inhibitors

    2010-01-01

    This thesis is based on some selected topics in open topological string theory which I have worked on during my Ph.D. It comprises an introductory part where I have focused on the points most needed for the later chapters, trading completeness for conciseness and clarity. Then, following [12], we discuss tadpole cancellation for topological strings where we mainly show how its implementation is needed for ensuring the same "odd" moduli decoupling encountered in the closed theory. Next we move to analyse how the open and closed effective field theories for the B model interact writing the complete Lagrangian. We first check it deriving some already known tree level amplitudes in term of target space quantities, and then we extend the recipe to new results; later we implement open closed duality from a target field theory perspective. This last subject is also analysed from a worldsheet point of view extending the analysis of [13]. Some ideas for future research are briefly reported.

    2007-02-15

    We introduce multiple topic tracking (MTT) for iScore to better recommend news articles for users with multiple interests and to address changes in user interests over time. As an extension of the basic Rocchio algorithm, traditional topic detection and tracking, and single-pass clustering, MTT maintains multiple interest profiles to identify interesting articles for a specific user given user-feedback. Focusing on only interesting topics enables iScore to discard useless profiles to address changes in user interests and to achieve a balance between resource consumption and classification accuracy. Also by relating a topic's interestingness to an article's interestingness, iScore is able to achieve higher quality results than traditional methods such as the Rocchio algorithm. We identify several operating parameters that work well for MTT. Using the same parameters, we show that MTT alone yields high quality results for recommending interesting articles from several corpora. The inclusion of MTT improves iScore's performance by 9% to 14% in recommending news articles from the Yahoo! News RSS feeds and the TREC11 adaptive filter article collection. And through a small user study, we show that iScore can still perform well when only provided with little user feedback.

    J-Earth is a Geographic Information Systems (GIS) application used for viewing and processing satellite and airborne remote sensing data and includes NASA imagery such as ASTER, Landsat, MODIS, TIMS, as well as other geological, ecological, and social datasets. The J-Earth team is working with the National Science Foundation-funded Central Arizona-Phoenix Long Term Ecological Research Project (CAP LTER) to incorporate its data and develop functionality for J-Earth. J-Earth was developed by the Arizona State University Mars Space Flight Facility as part of the JMARS (Java Mission-planning and Analysis for Remote Sensing) suite of open-source tools. J-Earth has been enhanced to support the needs of CAP LTER users with the use of web tutorials, social networking, user surveys and interviews. CAP LTER consists of an interdisciplinary urban ecology research group with different needs in the area of socio-ecological systems. Adapting J-Earth for the CAP LTER community has provided a test of J-Earth’s functionality for interdisciplinary datasets and has shown the potential for expanding J-Earth to include future users within the entire LTER network. This project could potentially be expanded to bring data from the other twenty-six LTER sites into J-Earth. J-Earth utilizes the analytical tools of JMARS and makes them available to a broad range of users. J-Earth utilizes a layered system to view data from different sources that can be exported, scaled, colored and superimposed for quick comparisons. The functionality of JMARS is focused on the planetary geology community, while J-Earth has the potential to be used by geologists, geographers, sociologists, and ecologists as well as policy makers. This presentation will provide an overview of information and feedback gathered from users of J-Earth, especially those of the CAP LTER. Collecting additional feedback in the form of social networking, interviews, trainings, and tutorials will help make J-Earth more functional and

    The Accellera Universal Verification Methodology (UVM) standard is architected to scale, but verification is growing and in more than just the digital design dimension. It is growing in the SoC dimension to include low-power and mixed-signal and the system integration dimension to include multi-language support and acceleration. These items and others all contribute to the quality of the SOC so the Metric-Driven Verification (MDV) methodology is needed to unify it all into a coherent verification plan. This book is for verification engineers and managers familiar with the UVM and the benefits it brings to digital verification but who also need to tackle specialized tasks. It is also written for the SoC project manager that is tasked with building an efficient worldwide team. While the task continues to become more complex, Advanced Verification Topics describes methodologies outside of the Accellera UVM standard, but that build on it, to provide a way for SoC teams to stay productive and profitable.

  10. Superconcentration and related topics

    Chatterjee, Sourav

    2014-01-01

    A certain curious feature of random objects, introduced by the author as “super concentration,” and two related topics, “chaos” and “multiple valleys,” are highlighted in this book. Although super concentration has established itself as a recognized feature in a number of areas of probability theory in the last twenty years (under a variety of names), the author was the first to discover and explore its connections with chaos and multiple valleys. He achieves a substantial degree of simplification and clarity in the presentation of these findings by using the spectral approach. Understanding the fluctuations of random objects is one of the major goals of probability theory and a whole subfield of probability and analysis, called concentration of measure, is devoted to understanding these fluctuations. This subfield offers a range of tools for computing upper bounds on the orders of fluctuations of very complicated random variables. Usually, concentration of measure is useful when more direct prob...

  11. Topics in statistical mechanics

    International Nuclear Information System (INIS)

    This thesis deals with four independent topics in statistical mechanics: (1) the dimer problem is solved exactly for a hexagonal lattice with general boundary using a known generating function from the theory of partitions. It is shown that the leading term in the entropy depends on the shape of the boundary; (2) continuum models of percolation and self-avoiding walks are introduced with the property that their series expansions are sums over linear graphs with intrinsic combinatorial weights and explicit dimension dependence; (3) a constrained SOS model is used to describe the edge of a simple cubic crystal. Low and high temperature results are derived as well as the detailed behavior near the crystal facet; (4) the microscopic model of the lambda-transition involving atomic permutation cycles is reexamined. In particular, a new derivation of the two-component field theory model of the critical behavior is presented. Results for a lattice model originally proposed by Kikuchi are extended with a high temperature series expansion and Monte Carlo simulation. 30 references

    In psychology there are two main branches of research into narcissism, clinical and social psychology. These approaches differ in their view of narcissism, the former treating it as a disorder, thus as discrete, and the latter treating it as a personality trait, thus as a continuum. There was a great deal of empirical research on narcissism in the Western psychological field. This research relied on the theoretical study of predecessors in social psychological research, explored undergraduate students' narcissism and its relationship with mental adaptation. The subjects, freshmen, sophomores, and juniors, came from different departments. 189 valid responses were analysed. The present investigation examined associations among gender, department, narcissism, mental adaptation and the 4 factors of mental adaptation. The results showed: (1) There wasn't a significant gender difference in Narcissism. But there was significant difference in mental adaptation~ Male students were better than female students in mental adaptation, (2) Students from different specialized subjects showed no significant difference in narcissism. But there was significant difference in mental adaptation. (3) Compared with narcissism and 4 factors of mental adaptation, there was a relationship between narcissism with mental self-control and self-confidence.%西方心理学界对自恋已有大量的实证研究,文章在依托前人研究的基础上,对大学生自恋与心理适应性的关系进行实证研究,结果表明,(1)男女生在自恋方面无显著性差异,在心理适应性方面存在显著性差异。男生的心理适应性均分高于女生。(2)不同系不同专业的学生,自恋方面无显著性差异,心理适应性方面呈显著性差异。(3)自恋与心理适应性的4个因子的关系研究显示,自恋与心理自控力、自信心有关系。

  19. Discovering health topics in social media using topic models.

    Directory of Open Access Journals (Sweden)

    Michael J Paul

    Full Text Available By aggregating self-reported health statuses across millions of users, we seek to characterize the variety of health information discussed in Twitter. We describe a topic modeling framework for discovering health topics in Twitter, a social media website. This is an exploratory approach with the goal of understanding what health topics are commonly discussed in social media. This paper describes in detail a statistical topic model created for this purpose, the Ailment Topic Aspect Model (ATAM, as well as our system for filtering general Twitter data based on health keywords and supervised classification. We show how ATAM and other topic models can automatically infer health topics in 144 million Twitter messages from 2011 to 2013. ATAM discovered 13 coherent clusters of Twitter messages, some of which correlate with seasonal influenza (r = 0.689 and allergies (r = 0.810 temporal surveillance data, as well as exercise (r =  .534 and obesity (r =  -.631 related geographic survey data in the United States. These results demonstrate that it is possible to automatically discover topics that attain statistically significant correlations with ground truth data, despite using minimal human supervision and no historical data to train the model, in contrast to prior work. Additionally, these results demonstrate that a single general-purpose model can identify many different health topics in social media.

You will then learn how to install and work with the MALLET natural language processing toolkit to do so. MALLET involves modifying an environment variable (essentially, setting up a short-cut so that your computer always knows where to find the MALLET program and working with the command line (ie, by typing in commands manually, rather than clicking on icons or menus. We will run the topic modeller on some example files, and look at the kinds of outputs that MALLET installed. This will give us a good idea of how it can be used on a corpus of texts to identify topics found in the documents without reading them individually.

    simulations 'would be seriously in error'. One may ask if this magazine should give space to Lindzen or those involved in geoengineering to air their views. Given the uncertainties still present within climate models and the potential costs of dealing with global warming, it would be wrong for Physics World to ignore those outside the mainstream. After all, as Richard Feynman once wrote: 'There is no harm in doubt and scepticism, for it is through these that new discoveries are made'. Physicists should never take anything at face value, not least a topic as important as climate change. (U.K.)

  8. Seven topics in functional magnetic resonance imaging.

    2009-09-01

    Functional MRI (fMRI) is a non-invasive brain imaging methodology that started in 1991 and allows human brain activation to be imaged at high resolution within only a few minutes. Because it has extremely high sensitivity, is relatively easy to implement, and can be performed on most standard clinical MRI scanners. It continues to grow at an explosive rate throughout the world. Over the years, at any given time, fMRI has been defined by only a handful of major topics that have been the focus of researchers using and developing the methodology. In this review, I attempt to take a snapshot of the field of fMRI as it is in mid-2009 by discussing the seven topics that I feel are most on the minds of fMRI researchers. The topics are, in no particular order or grouping: (1) Clinical impact, (2) Utilization of individual functional maps, (3) fMRI signal interpretation, (4) Pattern effect mapping and decoding, (5) Endogenous oscillations, (6) MRI technology, and (7) Alternative functional contrast mechanisms. Most of these topics are highly interdependent, each advancing as the others advance. While most fMRI involves applications towards clinical or neuroscience questions, all applications are fundamentally dependent on advances in basic methodology as well as advances in our understanding of the relationship between neuronal activity and fMRI signal changes. This review neglects almost completely an in-depth discussion of applications. Rather the discussions are on the methods and interpretation.

  9. Tracking Multiple Topics for Finding Interesting Articles

    Energy Technology Data Exchange (ETDEWEB)

    Pon, R K; Cardenas, A F; Buttler, D J; Critchlow, T J

    2008-01-03

    We introduce multiple topic tracking (MTT) for iScore to better recommend news articles for users with multiple interests and to address changes in user interests over time. As an extension of the basic Rocchio algorithm, traditional topic detection and tracking, and single-pass clustering, MTT maintains multiple interest profiles to identify interesting articles for a specific user given user-feedback. Focusing on only interesting topics enables iScore to discard useless profiles to address changes in user interests and to achieve a balance between resource consumption and classification accuracy. iScore is able to achieve higher quality results than traditional methods such as the Rocchio algorithm. We identify several operating parameters that work well for MTT. Using the same parameters, we show that MTT alone yields high quality results for recommending interesting articles from several corpora. The inclusion of MTT improves iScore's performance by 25% in recommending news articles from the Yahoo! News RSS feeds and the TREC11 adaptive filter article collection. And through a small user study, we show that iScore can still perform well when only provided with little user feedback.

    The primary treatment for superficial fungal infections is antifungal topical formulations, and allylamines and azoles represent the two major classes of topical formulations that are used to treat these infections. The stratum corneum (SC) is composed of keratinocytes that are surrounded by a matrix of lipids. The efficacy of topically applied formulations depends on their ability to penetrate this lipid matrix, and the vehicle plays an integral role in the penetration of active molecule into skin. There are several challenges to formulating topical drugs, which include the biotransformation of the active molecules as they pass through the SC and the physical changes that occur to the vehicle itself when it is applied to the skin. This article will review current and emerging topical antifungal vehicles. PMID:26885798

  8. Learning to Adapt. Organisational Adaptation to Climate Change Impacts

    International Nuclear Information System (INIS)

    Analysis of human adaptation to climate change should be based on realistic models of adaptive behaviour at the level of organisations and individuals. The paper sets out a framework for analysing adaptation to the direct and indirect impacts of climate change in business organisations with new evidence presented from empirical research into adaptation in nine case-study companies. It argues that adaptation to climate change has many similarities with processes of organisational learning. The paper suggests that business organisations face a number of obstacles in learning how to adapt to climate change impacts, especially in relation to the weakness and ambiguity of signals about climate change and the uncertainty about benefits flowing from adaptation measures. Organisations rarely adapt 'autonomously', since their adaptive behaviour is influenced by policy and market conditions, and draws on resources external to the organisation. The paper identifies four adaptation strategies that pattern organisational adaptive behaviour

  9. Mental Mechanisms for Topics Identification

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Topics identification (TI is the process that consists in determining the main themes present in natural language documents. The current TI modeling paradigm aims at acquiring semantic information from statistic properties of large text datasets. We investigate the mental mechanisms responsible for the identification of topics in a single document given existing knowledge. Our main hypothesis is that topics are the result of accumulated neural activation of loosely organized information stored in long-term memory (LTM. We experimentally tested our hypothesis with a computational model that simulates LTM activation. The model assumes activation decay as an unavoidable phenomenon originating from the bioelectric nature of neural systems. Since decay should negatively affect the quality of topics, the model predicts the presence of short-term memory (STM to keep the focus of attention on a few words, with the expected outcome of restoring quality to a baseline level. Our experiments measured topics quality of over 300 documents with various decay rates and STM capacity. Our results showed that accumulated activation of loosely organized information was an effective mental computational commodity to identify topics. It was furthermore confirmed that rapid decay is detrimental to topics quality but that limited capacity STM restores quality to a baseline level, even exceeding it slightly.

    2001-07-01

    The first chapter in this thesis is a survey of studies on electricity trade, which has been included in order to show how subjects in this thesis fit into this aspect of energy research. Transitions from centralised monopolies to liberalised electricity markets have been inaugurated in the northern European countries during the last decade. The backgrounds and speed of transitions differ within the countries. Where Norway liberalised its electricity market in order to stabilise the prices, EU urged a liberalisation in order to make the electricity supply industry more effective. Together with national liberalisation, the opening of the cross border trade between the countries is also urged. The first paper in this thesis describes those different liberalisation processes within northern Europe and discusses problems that may arise in a transition period for integrating the countries into a common electricity market with efficient cross-border competition. Before the liberalisation process started, the electricity generation was determined by a central load dispatch at known prices. The introduction of competition has necessitated the creation of new competitive markets, power exchanges and financial markets where generation and prices are determined by demand and supply on the markets. One implication of this is that investments in new plants shall be made under levels of uncertainty about future prices. The second paper in this thesis analyses the importance of introducing uncertainty in energy-economic modelling of the electricity supply sector. Another implication, which arises on introducing a new market structure and power exchanges, is that the design of the power exchanges influences the price setting on the markets. The third paper of this thesis analyses the price setting on the regulating power market on the Nordic power exchange Nord Pool. More precisely, the paper reveals the pattern of the prices on the regulating power market by analysing the cost of

    2016-03-01

    Full Text Available Wind energy is increasingly considered one of the most promising sustainable energy sources for its characteristics of cleanliness without any pollution. Wind speed forecasting is a vital problem in wind power industry. However, individual forecasting models ignore the significance of data preprocessing and model parameter optimization, which may lead to poor forecasting performance. In this paper, a novel hybrid [k, Bt] -ABBP (back propagation based on adaptive strategy with parameters k and Bt model was developed based on an adaptive boosting (AB strategy that integrates several BP (back propagation neural networks for wind speed forecasting. The fast ensemble empirical mode decomposition technique is initially conducted in the preprocessing stage to reconstruct data, while a novel modified FPA (flower pollination algorithm incorporating a conjugate gradient (CG is proposed for searching for the optimal parameters of the [k, Bt] -ABBP mode. The case studies of five wind power stations in Penglai, China are used as illustrative examples for evaluating the effectiveness and efficiency of the developed hybrid forecast strategy. Numerical results show that the developed hybrid model is simple and can satisfactorily approximate the actual wind speed series. Therefore, the developed hybrid model can be an effective tool in mining and analysis for wind power plants.

    Full Text Available Jonisha Shepherd,1 Arash Taheri,1 Steven R Feldman1–31Center for Dermatology Research, Department of Dermatology, 2Department of Pathology, 3Department of Public Health Sciences, Wake Forest School of Medicine, Winston-Salem, NC, USABackground: Topical treatments are usually effective in mild psoriasis. However, the complexity of their use may result in low patient adherence with treatment. Combination of a vitamin D analog and a corticosteroid into a two-compound topical formulation has increased efficacy compared with either drug administered alone. Once-daily application of such a product would likely improve adherence. The purpose of this study was to determine whether twice-daily application of a calcipotriene + betamethasone topical formulation can provide improved clinical outcomes compared with once-daily treatment with the same product.Methods: A review of the literature was performed seeking clinical trials comparing once-daily versus twice-daily application of calcipotriene + betamethasone topical formulations for the treatment of psoriasis.Results: We found only one relevant clinical trial. This study showed similar efficacy and safety with once-daily versus twice-daily application of a topical calcipotriene + betamethasone formulation in the treatment of psoriasis vulgaris.Conclusion: Once-daily application of a topical calcipotriene + betamethasone formulation may offer increased patient convenience and potentially increased patient adherence with long-term treatment, compared with twice-daily use, without reducing the efficacy. In order to enhance adherence, patient preference regarding frequency of application of topical treatments should be considered when prescribing medications.Keywords: calcipotriene, betamethasone, once daily, twice daily, psoriasis, combination product

    2014-01-01

    Do different field of knowledge require different research strategies? A numerical model exploring different virtual knowledge landscapes, revealed different optimal search strategies. Trend following is maximized when the popularity of new discoveries determine the number of individuals researching it. This strategy works best when many researchers explore few large areas of knowledge. In contrast, individuals or small groups of researchers are better in discovering small bits of information in dispersed knowledge landscapes. The best technique for all situations simulated, is to adjust the number of researchers needed to explore a knowledge cluster according to the opportunities and the level of crowding in that cluster. Bibliometric data of scientific publications showed a continuous bipolar distribution of these strategies, ranging from natural sciences, with highly cited publications in journals containing a large number of articles, to the social sciences, with rarely cited publications in journals cont...

    Owing to its ability to regenerate epidermal cells Dexpanthenol (D-panthenol; chemically known as (+)-2,4-dihydroxy-N-(3-hydroxypropyl)-3,3-dimethylbutyramide) has found use for the treatment of patholytic ileus and postoperative distention. The purpose of research was to develop a gel containing dexpanthenol by monitoring the effect of various concentrations of a gelating agent on the activity of the ciliary apparatus. A system containing 2.5% of hydroxyethylcellulose was optimal for the preparation of the gel. Together with a formulation containing 5% of dexpanthenol, drops with equal concentration of the active compound were tested for comparison. Physical characteristics, such as osmotic pressure, acidity, density and viscosity of the preparation were determined as well as its microbiological sterility. The anti-inflammatory activity of the gel was determined following its topical application. Epidermal tests showed its good tolerance after topical application to the shaved skin of guinea pigs.

    Full Text Available Introduction Understanding of fluid shifts and recognition of the importance of early and appropriate fluid replacement therapy have significantly reduced mortality in the early post burn period. After the bum patient successfully passes the resuscitation period, the burn wound represents the greatest threat to survival. History Since the dawn of civilization, man has been trying to find an agent which would help burn wounds heal, and at the same time, not harm general condition of the injured. It was not until the XX century, after the discovery of antibiotics, when this condition was fulfilled. In 1968, combining silver and sulfadiazine, fox made silver-sulfadiazine, which is a 1% hydro-soluble cream and a superior agent in topical treatment of burns today. Current topical agents None of the topical antimicrobial agents available today, alone or combined, have the characteristics of ideal prophylactic agents, but they eliminate colonization of burn wound, and invasive infections are infrequent. With an excellent spectrum of activity, low toxicity, and ease of application with minimal pain, silver-sulfadiazine is still the most frequently used topical agent. Conclusion The incidence of invasive infections and overall mortality have been significantly reduced after introduction of topical burn wound antimicrobial agents into practice. In most burn patients the drug of choice for prophylaxis is silver sulfadiazine. Other agents may be useful in certain clinical situations.

  17. Research on application of active disturbance rejection control based on adaptive GA in water level control of steam generator

    International Nuclear Information System (INIS)

    The steam generator of nuclear power plant is a nonlinear, time-varying system. Application of the active disturbance rejection control method in the water level control of steam generator can solve the contradiction between speed and overshoot in the conventional PID control system, and it also can compensate the internal and external disturbances of the object model dynamically. However, ADRC parameters are numerous and without uniform adjustment specification, and are very difficult to be tuned. In order to overcome the difficulties in the parameter tuning of the ADRC, the adaptive genetic algorithm is used to tune ADRC parameters. The simulation results show that its robustness and its control quality are better than those of the traditional cascade PID control. (authors)

    Full Text Available U-model can approximate a large class of smooth nonlinear time-varying delay system to any accuracy by using time-varying delay parameters polynomial. This paper proposes a new approach, namely, U-model approach, to solving the problems of analysis and synthesis for nonlinear systems. Based on the idea of discrete-time U-model with time-varying delay, the identification algorithm of adaptive neural network is given for the nonlinear model. Then, the controller is designed by using the Newton-Raphson formula and the stability analysis is given for the closed-loop nonlinear systems. Finally, illustrative examples are given to show the validity and applicability of the obtained results.

    Nowadays, for gait instability phenomenon, many researches have been carried out at home and abroad. However, the relationship between plantar pressure and gait parameters in the process of balance adjustment is still unclear. This study describes the human body adaptive balance reaction during slip events on slippery level walk by plantar pressure and gait analysis. Ten healthy male subjects walked on a level path wearing shoes with two contrastive contaminants (dry, oil). The study collected and analyzed the change rule of spatiotemporal parameters, plantar pressure parameters, vertical ground reaction force (VGRF), etc. The results showed that the human body adaptive balance reaction during slip events on slippery level walk mainly included lighter touch at the heel strikes, tighter grip at the toe offs, a lower velocity, a shorter stride length and longer support time. These changes are used to maintain or recover body balance. These results would be able to explore new ideas and provide reference value for slip injury prevention, walking rehabilitation training design, research and development of walking assistive equipments, etc. PMID:27079090

  4. Web mining for topics defined by complex and precise predicates

    The enormous growth of the World Wide Web has made it important to perform resource discovery efficiently for any given topic. Several new techniques have been proposed in the recent years for this kind of topic specific web-mining, and among them a key new technique called focused crawling which is able to crawl topic-specific portions of the web without having to explore all pages. Most existing research on focused crawling considers a simple topic definition that typically consists of one or more keywords connected by an OR operator. However this kind of simple topic definition may result in too many irrelevant pages in which the same keyword appears in a wrong context. In this research we explore new strategies for crawling topic specific portions of the web using complex and precise predicates. A complex predicate will allow the user to precisely specify a topic using Boolean operators such as "AND", "OR" and "NOT". Our work will concentrate on defining a format to specify this kind of a complex topic definition and secondly on devising a crawl strategy to crawl the topic specific portions of the web defined by the complex predicate, efficiently and with minimal overhead. Our new crawl strategy will improve the performance of topic-specific web crawling by reducing the number of irrelevant pages crawled. In order to demonstrate the effectiveness of the above approach, we have built a complete focused crawler called "Eureka" with complex predicate support, and a search engine that indexes and supports end-user searches on the crawled pages.

  5. Genomics of local adaptation with gene flow.

    2016-05-01

    Gene flow is a fundamental evolutionary force in adaptation that is especially important to understand as humans are rapidly changing both the natural environment and natural levels of gene flow. Theory proposes a multifaceted role for gene flow in adaptation, but it focuses mainly on the disruptive effect that gene flow has on adaptation when selection is not strong enough to prevent the loss of locally adapted alleles. The role of gene flow in adaptation is now better understood due to the recent development of both genomic models of adaptive evolution and genomic techniques, which both point to the importance of genetic architecture in the origin and maintenance of adaptation with gene flow. In this review, we discuss three main topics on the genomics of adaptation with gene flow. First, we investigate selection on migration and gene flow. Second, we discuss the three potential sources of adaptive variation in relation to the role of gene flow in the origin of adaptation. Third, we explain how local adaptation is maintained despite gene flow: we provide a synthesis of recent genomic models of adaptation, discuss the genomic mechanisms and review empirical studies on the genomics of adaptation with gene flow. Despite predictions on the disruptive effect of gene flow in adaptation, an increasing number of studies show that gene flow can promote adaptation, that local adaptations can be maintained despite high gene flow, and that genetic architecture plays a fundamental role in the origin and maintenance of local adaptation with gene flow.

  6. How can clinical biobanks and patient information be adapted for research – Establishing a hospital based data warehouse solution

    Full Text Available The use of human biological material and related clinical information is central in basic research, translational research and clinical research. Extracting this information from hospital information systems is time-consuming and labor intensive. Establishing a data warehouse is a possible solution to extract the information in an efficient and secure way. An information model for a data warehouse has been developed at the Oslo University Hospital in collaboration with Akershus University Hospital. Being hospitals, the overall information model is patientcentered. The model also allows for appropriate data exchange between different organizations. The model is described with a focus on some of the major conditions for success with respect to the legal and organizational framework of Norwegian hospitals. A web-based information and tracking system for clinical biobanks is an important element of the model, and one of the aims of the national project Biobank Norway

    Full Text Available Knowledge management (KM has received much attention from both academics and practitioners in the past few years. Following the KM trend, many organizations have built their own knowledge repositories or data warehouses. However, information or knowledge is still scattered everywhere without being properly managed. The rapid growth of the Internet accelerates the creation of unstructured and unclassified information and causes the explosion of information overload. The effort of browsing information through general-purpose search engines turns out to be tedious and painstaking. Hence, an effective technology to solve this information retrieval problem is much needed. The purpose of this research is to explore the application of text mining technique in organizing knowledge stored in unstructured natural language text documents. Major components of text mining techniques required for topic map in particular will be presented in detail.Two sets of unstructured documents are utilized to demonstrate the usage of SOM for topic categorization. The first set of documents is a collection of speeches given by Y.C. Wang, Chairman of the Taiwan Plastics Group, and the other is the collection of all laws and regulations related to securities and future markets in Taiwan. We also try to apply text mining to these two sets of documents to generate their respective topic maps, thus revealing the differences between organizing explicit and tacit knowledge as well as the difficulties associated with tacit knowledge.[Article content in Chinese

    The first ever symposium dedicated solely to drug delivery to the nail following topical application was held on the 2nd April 2007, in London, UK, organised by Dr Clive Roper (Charles River Laboratories, Scotland) and Dr Sudaxshina Murdan (School of Pharmacy, University of London, UK), under the auspices of Skin Forum. The 1-day meeting was attended by approximately 35 delegates from industry, academia and hospitals, and provided a much-needed forum for the presentation and discussion of research and problems in this emerging field. Topical drug delivery is especially suitable for onychomycosis (fungal infections of the nail plate and/or nail bed) and nail psoriasis, which affect 2 - 13 and 1 - 3% of the general population, respectively, and make up the bulk of nail disorders. Topical therapy would avoid the adverse events and drug interactions of systemic antifungal agents and the pain of injection when antipsoriatic agents are injected into affected nail folds. However, successful topical therapy is extremely challenging due to the very low permeability of the nail plate. Five speakers spoke about various aspects of topical drug delivery to the nail, including review of the nail plate structure, function, diseases, their existing therapies (systemic and topical), limitations and global sales. The need for effective topical drug delivery to the nail to overcome the problems associated with present treatment, and the fact that there are few topical formulations available for the treatment of nail fungal infections and psoriasis, and the even fewer effective formulations, was highlighted.

    Adaptive Lighting Adaptive lighting is based on a partial automation of the possibilities to adjust the colour tone and brightness levels of light in order to adapt to people’s needs and desires. IT support is key to the technical developments that afford adaptive control systems. The possibilities...... offered by adaptive lighting control are created by the ways that the system components, the network and data flow can be coordinated through software so that the dynamic variations are controlled in ways that meaningfully adapt according to people’s situations and design intentions. This book discusses...... distributed differently into an architectural body. We also examine what might occur when light is dynamic and able to change colour, intensity and direction, and when it is adaptive and can be brought into interaction with its surroundings. In short, what happens to an architectural space when artificial...

  14. The pharmacology of topical analgesics.

    2013-07-01

    Pain management of patients continues to pose challenges to clinicians. Given the multiple dimensions of pain--whether acute or chronic, mild, moderate, or severe, nociceptive or neuropathic--a multimodal approach may be needed. Fortunately, clinicians have an array of nonpharmacologic and pharmacologic treatment choices; however, each modality must be chosen carefully, because some often used oral agents are associated with safety and tolerability issues that restrict their use in certain patients. In particular, orally administered nonsteroidal antiinflammatory drugs, opioids, antidepressants, and anticonvulsants are known to cause systemic adverse effects in some patients. To address this problem, a number of topical therapies in various therapeutic classes have been developed to reduce systemic exposure and minimize the risks of patients developing adverse events. For example, topical nonsteroidal anti-inflammatory drug formulations produce a site-specific effect (ie, cyclo-oxygenase inhibition) while decreasing the systemic exposure that may lead to undesired effects in patients. Similarly, derivatives of acetylsalicylic acid (ie, salicylates) are used in topical analgesic formulations that do not significantly enter the patient's systemic circulation. Salicylates, along with capsaicin, menthol, and camphor, compose the counterirritant class of topical analgesics, which produce analgesia by activating and then desensitizing epidermal nociceptors. Additionally, patches and creams that contain the local anesthetic lidocaine, alone or co-formulated with other local anesthetics, are also used to manage patients with select acute and chronic pain states. Perhaps the most common topical analgesic modality is the cautious application of cutaneous cold and heat. Such treatments may decrease pain not by reaching the target tissue through systemic distribution, but by acting more directly on the affected tissue. Despite the tolerability benefits associated with avoiding

  15. An Interdisciplinary and Intersectoral Action-research Method: Case-Study of Climate Change Adaptation by Cities Using Participatory Web 2.0 Urban Design

    Geneviève VACHON

    2014-01-01

    Full Text Available This paper discusses the last segment of a three-year interdisciplinary and intersectoral action research on climate change and urban transformation. The project had, as one of its core missions, the role of imagining urban and architectural adaptations for urban neighbourhoods that would contribute to minimizing the negative impacts of climate change on people’s comfort, health and safety. The first part of the paper describes the collaborative design and augmented participation method used in the context of Québec City, Canada. These include the design process conducted to imagine adaptation scenarios, the visual strategies undertaken to make these understandable for the population, and the Web 2.0 crowdsourcing approach forwarded to measure feasibility and social acceptability of the design and visualization strategies. The second part discusses three positive outcomes of the process. First, collaborative design conducted with intersectoral groups of experts constitutes a promising avenue to identify adaptations and evaluate their relevance. Second, crowdsourcing is a powerful tool to inform the general public about climate change including both negative and potential aspects. As well, the crowdsource model allows access to particular knowledge which empowered users to make changes around their homes and neighbourhoods or advocating action from their local government. Crowdsourcing is also an efficient tool to help understand what people know about the potential impact of climate change and how it bears on their comfort, health and safety. Third and finally, the design proposals and the evaluation comments generated by working closely with various stakeholders, along with the public on-line consultation, allow for the induction of pragmatic recommendations that can be used as decision aids by elected officials and civil servants to better prepare their municipalities for climate change.

    Working knowledge of the relations of various quantities and their derivatives across a shock wave is useful for any advanced research involving shock waves. Although these relations can be derived in principle by any diligent student of the subject, the derivations are often not trivial, and once derived, neither the approach nor the result can be confidently verified. Comprehensive and analytical, Shock Wave Dynamics: Derivatives and Related Topics includes not only the final results but also the methods, which are of great practical value as examples of mathematical procedure in this field.

    Painter, Sally L; Hildebrand, Göran Darius

    2016-01-01

    The treatment of infantile hemangiomas changed from the use of oral corticosteroids to oral propranolol on the serendipitous discovery of propanolol's clinical effectiveness in 2008. Since then, clinicians have begun to use topical beta blockers--in particular, timolol maleate 0.5% gel forming solution--with good effect. Topical beta blockers are now used for lesions with both deep and superficial components and those that are amblyogenic. When initiated in the proliferative phase of the lesion, the effectiveness of the treatment can be seen within days. There is no consensus on dosing, treatment bioavailability, or clinical assessment of lesions, but these are topics for future research.

    In order to improve the security of batch steganography,this paper proposed a novel adaptive batch steganography system.First,it estimated embedding capacity of images under current steganalysis techniques by bringing ensemble classifier based on random forest into steganalysis,then distributed message bits to the images according to their embedding capacities.The new system could make full use of the images and improve batch steganography security further by dividing the message into groups.Experimental results show that the new security definition decreases the total detection error and running time,having a good balance between missed detection rate and false alarm rate.%为了进一步提高批量隐写的安全性,针对以往自适应批量隐写方案的不足设计了一种简单可靠的新方案.首先借助基于随机森林的集成分类器确定当前隐写分析技术下图像的隐写容量,在此基础上确定各个图像嵌入的信息量,方案最大程度地利用了载体资源,并通过对秘密信息进行分割分组进一步增强了安全性.实验结果表明,隐写容量计算中的安全判定方法准确性高,在保证低漏检率的同时避免了较高的虚警率,且运行时间更短.

  20. Knowledge exchange for climate adaptation planning in western North America

    Garfin, Gregg; Orr, Barron

    2015-04-01

    In western North America, the combination of sustained drought, rapid ecosystem changes, and land use changes associated with urban population growth has motivated concern among ecosystem managers about the implications of future climate changes for the landscapes which they manage. Through literature review, surveys, and workshop discussions, we assess the process of moving from concern, to planning, to action, with an emphasis on questions, such as: What are the roles of boundary organizations in facilitating knowledge exchange? Which practices lead to effective interactions between scientists, decision-makers, and knowledge brokers? While there is no "one size fits all" science communication method, the co-production of science and policy by research scientists, science translators, and decision-makers, as co-equals, is a resource intensive, but effective practice for moving adaptation planning forward. Constructive approaches make use of alliances with early adopters and opinion leaders, and make strong communication links between predictions, impacts and solutions. Resource managers need information on the basics of regional climate variability and global climate change, region-specific projections of climate changes and impacts, frank discussion of uncertainties, and opportunities for candid exploration of these topics with peers and subject experts. Research scientists play critical roles in adaptation planning discussions, because they assist resource managers in clarifying the cascade of interactions leading to potential impacts and, importantly, because decision-makers want to hear the information straight from the scientists conducting the research, which bolsters credibility. We find that uncertainty, formerly a topic to avoided, forms the foundation for constructive progress in adaptation planning. Candid exploration of the array of uncertainties, including those due to modeling, institutional, policy and economic factors, with practitioners, science
