SIMONA RODAT

2014-12-01

Full Text Available The emergence of the opportunities opened by the internet raises also questions of interest for research regarding the extent to which these have an impact on the formations of non heterosexual life and on the experience of marginalised sexual identities. There have been different approaches in this regard and answers vary from optimistic and utopian appraisals concerning cyberspace in the early 90s to the more moderate and sceptic visions in the 2000s. Starting from this framework of debates, the present paper aims to explore the meaning of the term “cyberqueer”, including the theoretical context of its occurrence, to briefly highlight some critical considerations relating to cyberqueer research and to look over the main recurrent themes linked up with this concept, such as queer and cyberqueer identity, body and (disembodied practices and the forthcoming process of blurring the dividing boundaries between real/virtual, online/offline and public/private

Institutional Barriers to Research on Sensitive Topics: Case of Sex Communication Research Among University Students

Directory of Open Access Journals (Sweden)

Carey M. Noland

2012-11-01

Full Text Available When conducting research on sensitive topics, it is challenging to use new methods of data collection given the apprehensions of Institutional Review Boards (IRBs. This is especially worrying because sensitive topics of research often require novel approaches. In this article a brief personal history of navigating the IRB process for conducting sex communication research is presented, along with data from a survey that tested the assumptions long held by many IRBs. Results support some of the assumptions IRBs hold about sex communication research, but do not support some other assumptions.

Reflexive journaling on emotional research topics: ethical issues for team researchers.

Science.gov (United States)

Malacrida, Claudia

2007-12-01

Traditional epistemological concerns in qualitative research focus on the effects of researchers' values and emotions on choices of research topics, power relations with research participants, and the influence of researcher standpoints on data collection and analysis. However, the research process also affects the researchers' values, emotions, and standpoints. Drawing on reflexive journal entries of assistant researchers involved in emotionally demanding team research, this article explores issues of emotional fallout for research team members, the implications of hierarchical power imbalances on research teams, and the importance of providing ethical opportunities for reflexive writing about the challenges of doing emotional research. Such reflexive approaches ensure the emotional safety of research team members and foster opportunities for emancipatory consciousness among research team members.

How are topics born? Understanding the research dynamics preceding the emergence of new areas

Full Text Available The ability to promptly recognise new research trends is strategic for many stakeholders, including universities, institutional funding bodies, academic publishers and companies. While the literature describes several approaches which aim to identify the emergence of new research topics early in their lifecycle, these rely on the assumption that the topic in question is already associated with a number of publications and consistently referred to by a community of researchers. Hence, detecting the emergence of a new research area at an embryonic stage, i.e., before the topic has been consistently labelled by a community of researchers and associated with a number of publications, is still an open challenge. In this paper, we begin to address this challenge by performing a study of the dynamics preceding the creation of new topics. This study indicates that the emergence of a new topic is anticipated by a significant increase in the pace of collaboration between relevant research areas, which can be seen as the ‘parents’ of the new topic. These initial findings (i confirm our hypothesis that it is possible in principle to detect the emergence of a new topic at the embryonic stage, (ii provide new empirical evidence supporting relevant theories in Philosophy of Science, and also (iii suggest that new topics tend to emerge in an environment in which weakly interconnected research areas begin to cross-fertilise.

–1843, 2015), the most serious problems are the lack of an acknowledged definition of emergence and incomplete elaboration of the linkages between the definitions that are used and the indicators that are created. With these issues in mind, this study first adjusts the definition of an emerging technology...... that Rotolo et al. (2015) have proposed to accommodate the analysis. Next, a set of criteria for the identification of emerging topics is proposed according to the adjusted definition and attributes of emergence. Using two sets of parameter values, several emerging research topics are identified. Finally...

Evaluation of research topic evolution in psychiatry using co-word analysis.

Science.gov (United States)

Wu, Ying; Jin, Xing; Xue, Yunzhen

2017-06-01

With the rapid increase in the incidence of mental disorders and mental issues, psychiatry has become one of the fastest growing clinical medical disciplines. Development priorities and research foci in this field have evolved over different periods.All the articles in 10 psychiatric journals with the highest impact factors were selected from the Science Citation Index (SCI) in Web of Science from 2001 to 2015. The information visualization software Sci was used to conduct co-word and clustering analyses on these articles. The articles were divided into 3 periods: 2001 to 2005, 2006 to 2010, and 2011 to 2015. Each bibliographic record contained a title, author names, abstract, keywords, references, and other information.During the 3 periods between 2001 and 2015, child and adolescent psychiatry, major depression, schizophrenia, and prefrontal cortex were constant research foci. The brain and meta-analysis gradually became new research foci, although research on symptoms slowly decreased. Molecular genetics was also an area of interest.Using scientometrics technology to visualize research foci can provide us with new ideas and research methods. Co-word analysis for the preliminary exploration of research foci and developmental trends in psychiatry is helpful in finding developmental rules, choices of topics, and innovative research. Our study had some limitations. In the future, we should expand our research scope and use a variety of research methods to enrich our results.

Uncovering the Topic Landscape of Product-Service System Research: from Sustainability to Value Creation

Directory of Open Access Journals (Sweden)

Hakyeon Lee

2018-03-01

Full Text Available As the product-service system (PSS is considered a promising business model that can create more value for customers, PSS research has enjoyed remarkable growth in its volume and coverage over the last decade. This study aims to delineate the thematic landscape of PSS research by identifying latent topics from a large amount of scholarly data. Ten topics of PSS research are identified by applying the Latent Dirichlet Allocation (LDA model to 1229 PSS publications published between 2000 and 2016. The ten PSS topics are briefly reviewed to provide an overview of what has previously been studied in PSS research. We also investigate which topics rise or fall in popularity by identifying hot and cold topics of PSS research. It is observed that the focus of discussions on the benefits of PSS has shifted from sustainability to value creation. Also, increasing attention has been paid to more practical topics such as PSS implementation. The areas of subspecialty of the top ten PSS journals are also examined to explore the interdisciplinary nature of PSS research and thematic differences across disciplines. The findings of this study can provide rich implications for both academia and practice in the field of PSS.

2018-03-01

The ALLIANCE 6 Strategic Research Agenda (SRA) initiated by the STAR 7 Network of Excellence and integrated in the research strategy implemented by the COMET consortium, defines a long-term vision of the needs for, and implementation of, research in radioecology. This reference document, reflecting views from many stakeholders groups and researchers, serves as an input to those responsible for defining EU research call topics through the ALLIANCE SRA statement delivered each year to the EJP-CONCERT 8 (2015-2020). This statement highlights a focused number of priorities for funding. Research in radioecology and related sciences is justified by various drivers, such as policy changes, scientific advances and knowledge gaps, radiological risk perception by the public, and a growing awareness of interconnections between human and ecosystem health. The SRA is being complemented by topical roadmaps that have been initiated by the COMET 9 EC-funded project, with the help and endorsement of the ALLIANCE. The strategy underlying roadmap development is driven by the need for improved mechanistic understanding across radioecology. By meeting this need, we can provide fit-for-purpose human and environmental impact/risk assessments in support of the protection of man and the environment in interaction with society and for the three exposure situations defined by the ICRP (i.e., planned, existing and emergency). Within the framework of the EJP-CONCERT the development of a joint roadmap is under discussion among all the European research platforms and will highlight the major research needs for the whole radiation protection field and how these are likely to be addressed by 2030.

Risk to researchers in qualitative research on sensitive topics: issues and strategies.

Science.gov (United States)

Dickson-Swift, Virginia; James, Erica L; Kippen, Sandra; Liamputtong, Pranee

2008-01-01

Traditionally, risk assessments in research have been limited to examining the risks to the research participants. Although doing so is appropriate and important, there is growing recognition that undertaking research can pose risks to researchers as well. A grounded theory study involving a range of researchers who had undertaken qualitative health research on a sensitive topic was completed. Analysis of the in-depth, face-to-face unstructured individual interviews with 30 Australian public health researchers provided evidence that researchers do confront a number of physical and emotional risks when undertaking research. Training, preparation, and supervision must be taken into account so that the risk to researchers can be minimized. Researchers need to consider occupational health and safety issues in designing research projects that deal with physical and emotional risks. Recommendations for professional supervision, policy development, and minimum training standards for researchers are provided.

Identifying biological concepts from a protein-related corpus with a probabilistic topic model

Directory of Open Access Journals (Sweden)

Lu Xinghua

2006-02-01

Full Text Available Abstract Background Biomedical literature, e.g., MEDLINE, contains a wealth of knowledge regarding functions of proteins. Major recurring biological concepts within such text corpora represent the domains of this body of knowledge. The goal of this research is to identify the major biological topics/concepts from a corpus of protein-related MEDLINE© titles and abstracts by applying a probabilistic topic model. Results The latent Dirichlet allocation (LDA model was applied to the corpus. Based on the Bayesian model selection, 300 major topics were extracted from the corpus. The majority of identified topics/concepts was found to be semantically coherent and most represented biological objects or concepts. The identified topics/concepts were further mapped to the controlled vocabulary of the Gene Ontology (GO terms based on mutual information. Conclusion The major and recurring biological concepts within a collection of MEDLINE documents can be extracted by the LDA model. The identified topics/concepts provide parsimonious and semantically-enriched representation of the texts in a semantic space with reduced dimensionality and can be used to index text.

Sing, David C; Metz, Lionel N; Dudli, Stefan

2017-06-01

Retrospective review. To identify the top 100 spine research topics. Recent advances in "machine learning," or computers learning without explicit instructions, have yielded broad technological advances. Topic modeling algorithms can be applied to large volumes of text to discover quantifiable themes and trends. Abstracts were extracted from the National Library of Medicine PubMed database from five prominent peer-reviewed spine journals (European Spine Journal [ESJ], The Spine Journal [SpineJ], Spine, Journal of Spinal Disorders and Techniques [JSDT], Journal of Neurosurgery: Spine [JNS]). Each abstract was entered into a latent Dirichlet allocation model specified to discover 100 topics, resulting in each abstract being assigned a probability of belonging in a topic. Topics were named using the five most frequently appearing terms within that topic. Significance of increasing ("hot") or decreasing ("cold") topic popularity over time was evaluated with simple linear regression. From 1978 to 2015, 25,805 spine-related research articles were extracted and classified into 100 topics. Top two most published topics included "clinical, surgeons, guidelines, information, care" (n = 496 articles) and "pain, back, low, treatment, chronic" (424). Top two hot trends included "disc, cervical, replacement, level, arthroplasty" (+0.05%/yr, P < 0.001), and "minimally, invasive, approach, technique" (+0.05%/yr, P < 0.001). By journal, the most published topics were ESJ-"operative, surgery, postoperative, underwent, preoperative"; SpineJ-"clinical, surgeons, guidelines, information, care"; Spine-"pain, back, low, treatment, chronic"; JNS- "tumor, lesions, rare, present, diagnosis"; JSDT-"cervical, anterior, plate, fusion, ACDF." Topics discovered through latent Dirichlet allocation modeling represent unbiased meaningful themes relevant to spine care. Topic dynamics can provide historical context and direction for future research for aspiring investigators and trainees

Knowledge of epidemiologic research topics as well as trends is useful for scientific societies, researchers and funding agencies. In recent years researchers recognized the usefulness of keyword network analysis for visualizing and analyzing scientific research topics. Therefore, we applied keyword network analysis to present an overview of current epidemiologic research topics in Germany. Accepted submissions to the 9th annual congress of the German Society for Epidemiology (DGEpi) in 2014 were used as data source. Submitters had to choose one of 19 subject areas, and were ask to provide a title, structured abstract, names of authors along with their affiliations, and a list of freely selectable keywords. Keywords had been provided for 262 (82 %) submissions, 1030 keywords in total. Overall the most common keywords were: "migration" (18 times), "prevention" (15 times), followed by "children", "cohort study", "physical activity", and "secondary data analysis" (11 times each). Some keywords showed a certain concentration under one specific subject area, e.g. "migration" with 8 of 18 in social epidemiology or "breast cancer" with 4 of 7 in cancer epidemiology. While others like "physical activity" were equally distributed over multiple subject areas (cardiovascular & metabolic diseases, ageing, methods, paediatrics, prevention & health service research). This keyword network analysis demonstrated the high diversity of epidemiologic research topics with a large number of distinct keywords as presented at the annual conference of the DGEpi.

Pharmaceutical lobbying in Brazil: a missing topic in the public health research agenda.

Science.gov (United States)

Paumgartten, Francisco José Roma

2016-12-22

In the US, where registration of lobbyists is mandatory, the pharmaceutical industry and private health-care providers spend huge amounts of money seeking to influence health policies and government decisions. In Brazil, where lobbying lacks transparency, there is virtually no data on drug industry expenditure to persuade legislators and government officials of their viewpoints and to influence decision-making according to commercial interests. Since 1990, however, the Associação da Indústria Farmacêutica de Pesquisa (Interfarma - Pharmaceutical Research Industry Association), Brazilian counterpart of the Pharmaceutical Research and Manufacturers of America (PhRMA), main lobbying organization of the US pharmaceutical industry, has played a major role in the advocacy of interests of major drug companies. The main goals of Interfarma lobbying activities are: shortening the average time taken by the Brazilian regulatory agency (ANVISA) to approve marketing authorization for a new drug; making the criteria for incorporation of new drugs into SUS (Brazilian Unified Health System) more flexible and speeding up technology incorporation; changing the Country's ethical clearance system and the ethical requirements for clinical trials to meet the need of the innovative drug industry, and establishing a National Policy for Rare Diseases that allows a prompt incorporation of orphan drugs into SUS. Although lobbying affects community health and well-being, this topic is not in the public health research agenda. The impacts of pharmaceutical lobbying on health policies and health-care costs are of great importance for SUS and deserve to be investigated.

Fair Resource Allocation to Health Research: Priority Topics for Bioethics Scholarship.

Science.gov (United States)

Pratt, Bridget; Hyder, Adnan A

2017-07-01

This article draws attention to the limited amount of scholarship on what constitutes fairness and equity in resource allocation to health research by individual funders. It identifies three key decisions of ethical significance about resource allocation that research funders make regularly and calls for prioritizing scholarship on those topics - namely, how health resources should be fairly apportioned amongst public health and health care delivery versus health research, how health research resources should be fairly allocated between health problems experienced domestically versus other health problems typically experienced by disadvantaged populations outside the funder's country, and how domestic and non-domestic health research funding should be further apportioned to different areas, e.g. types of research and recipients. These three topics should be priorities for bioethics research because their outcomes have a substantial bearing on the achievement of health justice. The proposed agenda aims to move discussion on the ethics of health research funding beyond its current focus on the mismatch between worldwide basic and clinical research investment and the global burden of disease. Individual funders' decision-making on whether and to what extent to allocate resources to non-domestic health research, health systems research, research on the social determinants of health, capacity development, and recipients in certain countries should also be the focus of ethical scrutiny. © 2017 John Wiley & Sons Ltd.

Assessment of Research Reactors (INSARR) missions. The prime objective of these missions has been to conduct a comprehensive operational safety review of the research reactor facility and to verify compliance with the IAEA Safety Standards. The methods used during an INSARR mission have been collected and analysed. Some of the important issues identified are the following: general ageing of the facility; uncertain status of many research reactors (in extended shutdown); indefinite deferral of return to operation or decommissioning; inadequate regulatory supervision; insufficient systematic (periodic) reassessment of safety; lack of quality assurance (QA) programmes; lack of an international safety convention or arrangement; lack of financial support for safety measures (e.g. safety reassessment, safety upgrading, decommissioning) and utilization; lack of clear utilization programmes; inadequate emergency preparedness; inadequate safety documentation (e.g. safety analysis report, operating rules and procedures, emergency plan); inadequate funding of shutdown reactors; weak safety culture; loss of expertise and corporate memory; loss of information concerning radioactive materials contained in retired experimental devices stored in the facility indefinitely; obsolescence of equipment and lack of spare parts; inadequate training and qualifications of regulators and operators; safety implications of new fuel types. These issues have been addressed by the IAEA Secretariat and the chairman of the International Nuclear Safety Advisory Group (INSAG). INSAG has identified three major safety issues that are: the increasing age of research reactors, the number of research reactors that are not operating anymore but have not been decommissioned, and the number of research reactors in countries that do not have appropriate regulatory authorities. This issue paper discusses the concerns generated by an analysis of the results of INSARR missions and those expressed by INSAG. The

Environmental justice (EJ) research seeks to document and redress the disproportionate environmental burdens and benefits associated with social inequalities. Although its initial focus was on disparities in exposure to anthropogenic pollution, the scope of EJ research has expanded. In the context of intensifying social inequalities and environmental problems, there is a need to further strengthen the EJ research framework and diversify its application. This Special Issue of the International Journal of Environmental Research and Public Health (IJERPH) incorporates 19 articles that broaden EJ research by considering emerging topics such as energy, food, drinking water, flooding, sustainability, and gender dynamics, including issues in Canada, the UK, and Eastern Europe. Additionally, the articles contribute to three research themes: (1) documenting connections between unjust environmental exposures and health impacts by examining unsafe infrastructure, substance use, and children's obesity and academic performance; (2) promoting and achieving EJ by implementing interventions to improve environmental knowledge and health, identifying avenues for sustainable community change, and incorporating EJ metrics in government programs; and (3) clarifying stakeholder perceptions of EJ issues to extend research beyond the documentation of unjust conditions and processes. Collectively, the articles highlight potentially compounding injustices and an array of approaches being employed to achieve EJ.

2017-08-01

Digital heritage comprises a broad variety of approaches and topics and involves researchers from multiple disciplines. While the use of digital methods in the text-oriented disciplines dealing with cultural heritage is widely discussed and canonized, an up-to-date investigation on cultural heritage as a scholarly field is currently missing. The extended abstract is about a three-stage investigation on standards, publications, disciplinary cultures as well as scholars in the field of digital heritage, carried out in 2016 and 2017. It includes results of a workshop-based survey involving 44 researchers, 15 qualitative interviews as well as an online survey with nearly 1000 participants. As an overall finding, a community is driven by researchers from European countries and especially Italy with a background in humanities, dealing with topics of data acquisition, data management and visualization. Moreover, conference series are most relevant for a scientific discourse, and especially EU projects set pace as most important research endeavours.

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

ENTRIA (''Disposal Options for Radioactive Residues: Interdisciplinary Analyses and Development of Evaluation Principles'', www.entria.de) is a joint research project carried out by twelve departments and institutes from German universities and major research institutions and one partner from Switzerland. It is financed by the German Ministry of Education and Research (BMBF). Scientists representing natural sciences, civil engineering, philosophy, law, social and political sciences, and technology assessment carry out disciplinary and interdisciplinary research addressing three options to manage especially high-level radioactive waste: - Final disposal in deep geological formations without any arrangements for retrieval, - disposal in deep geological formations with arrangements for monitoring and retrieval, and - (prolonged) surface (or near-surface) storage. In the paper, the following selected research topics - both disciplinary and interdisciplinary - are briefly introduced in order to provide an impression of the project scope: - Surface storage, - reference concepts for emplacement in deep geological formations with retrievability and monitoring, - radiation exposure and justification of measures, - interdisciplinary perspectives on dose limits, - comparative studies on nuclear waste governance, - nuclear waste governance in Switzerland, - public involvement and the German Site Selection Act, and - citizens' jury.

Salinas, Alejandro; González, Gregorio; Manuel Ramos, Jose

2016-09-01

Rheumatic fever and rheumatic heart disease (RHD) are important health problems in developing countries. The study aim was to provide a review and content analysis of the scientific literature on rheumatic fever and RHD over a 70-year period. Medline was employed via the online PubMed service of the US National Library of Medicine, to search for all documents containing the MeSH terms 'rheumatic fever' or 'rheumatic heart disease' between January 1945 and December 2013. A total of 18,552 references was retrieved. Between 1945 and 1970 the number of annual publications containing the search terms increased, but decreased between 1971 and 2013. Between 1990 and 2013, national collaboration (co-authorship) was greatly increased, from 8.7% to 41.7% of the total reports. International collaboration also increased, from 2.5% to 14.8% (p = 0.001). The United States was the main collaborating country, sharing ties mainly with India, South Africa and Brazil. A content analysis led to the identification of three prominent core research topics, chief among which were heart diseases (rheumatic fever diseases, mitral valve diseases and endocarditis). Other areas of note included streptococcal infections and rheumatic diseases (which, in addition to rheumatic fever, also highlighted arthritis and juvenile arthritis). Publications on rheumatic fever and RHD had a major impact during the 1960s, but research groups interest has since declined overall, in line with a decreasing interest in these diseases in developed countries. In contrast, national and international collaboration has increased, a phenomenon that should be encouraged for research into these and other diseases that affect developing countries.

Some topics on radioecological research in marine environment

International Nuclear Information System (INIS)

Shimizu, Makoto

1993-01-01

In Japan, systematic researches on marine environmental radioactivity started in 1954 when 'Bikini incidence' occurred. After several years of handling emergency situations, basic studies were carried out to understand processes and mechanisms of contamination of aquatic organisms by radionuclides. At this period 'Hiyama Group' had a large contribution to the development of this new field of research. Important concepts and items have already been dealt with in this Grant Group. Toward the end of 'Hiyama Group', a new project started in Nuclear Safety Research Association. This project, so-called 'Kaihohtoku', aimed at gathering necessary information for safety assessment on the release of low-level radioactive liquid wastes from a newly planned spent-fuel reprocessing plant at Tokai. NIRS-Nakaminato Branch was established first as Marine Radioecological Station in this project. The term 'radioecology' got popularity also in this period. Many important results were obtained and scientific basis of the safety assessment was established in this project. Today we have not any urgent matter to be handled concerning radioecology in our coastal environment. Nuclides found are exclusively of fallout and of a quite low level. We have also established methodology of radiological assessment. So, what is the problem? The problem is 'from conservative to realistic', which is the trend in the world. Here, from this viewpoint, some topics such as models and parameters including concentration factors and their validation and verification in the natural environment were discussed. (author)

Topic Modeling of NASA Space System Problem Reports: Research in Practice

Science.gov (United States)

Layman, Lucas; Nikora, Allen P.; Meek, Joshua; Menzies, Tim

2016-01-01

Problem reports at NASA are similar to bug reports: they capture defects found during test, post-launch operational anomalies, and document the investigation and corrective action of the issue. These artifacts are a rich source of lessons learned for NASA, but are expensive to analyze since problem reports are comprised primarily of natural language text. We apply topic modeling to a corpus of NASA problem reports to extract trends in testing and operational failures. We collected 16,669 problem reports from six NASA space flight missions and applied Latent Dirichlet Allocation topic modeling to the document corpus. We analyze the most popular topics within and across missions, and how popular topics changed over the lifetime of a mission. We find that hardware material and flight software issues are common during the integration and testing phase, while ground station software and equipment issues are more common during the operations phase. We identify a number of challenges in topic modeling for trend analysis: 1) that the process of selecting the topic modeling parameters lacks definitive guidance, 2) defining semantically-meaningful topic labels requires nontrivial effort and domain expertise, 3) topic models derived from the combined corpus of the six missions were biased toward the larger missions, and 4) topics must be semantically distinct as well as cohesive to be useful. Nonetheless,topic modeling can identify problem themes within missions and across mission lifetimes, providing useful feedback to engineers and project managers.

GeneTopics - interpretation of gene sets via literature-driven topic models

Science.gov (United States)

2013-01-01

Background Annotation of a set of genes is often accomplished through comparison to a library of labelled gene sets such as biological processes or canonical pathways. However, this approach might fail if the employed libraries are not up to date with the latest research, don't capture relevant biological themes or are curated at a different level of granularity than is required to appropriately analyze the input gene set. At the same time, the vast biomedical literature offers an unstructured repository of the latest research findings that can be tapped to provide thematic sub-groupings for any input gene set. Methods Our proposed method relies on a gene-specific text corpus and extracts commonalities between documents in an unsupervised manner using a topic model approach. We automatically determine the number of topics summarizing the corpus and calculate a gene relevancy score for each topic allowing us to eliminate non-specific topics. As a result we obtain a set of literature topics in which each topic is associated with a subset of the input genes providing directly interpretable keywords and corresponding documents for literature research. Results We validate our method based on labelled gene sets from the KEGG metabolic pathway collection and the genetic association database (GAD) and show that the approach is able to detect topics consistent with the labelled annotation. Furthermore, we discuss the results on three different types of experimentally derived gene sets, (1) differentially expressed genes from a cardiac hypertrophy experiment in mice, (2) altered transcript abundance in human pancreatic beta cells, and (3) genes implicated by GWA studies to be associated with metabolite levels in a healthy population. In all three cases, we are able to replicate findings from the original papers in a quick and semi-automated manner. Conclusions Our approach provides a novel way of automatically generating meaningful annotations for gene sets that are directly

Topic Model for Graph Mining.

Science.gov (United States)

Xuan, Junyu; Lu, Jie; Zhang, Guangquan; Luo, Xiangfeng

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.

Sikandar, Shafaq; Patel, Ryan; Patel, Sital; Sikander, Sanam; Bennett, David L.H.; Dickenson, Anthony H.

2013-01-01

This review selectively explores some areas of pain research that, until recently, have been poorly understood. We have chosen four topics that relate to clinical pain and we discuss the underlying mechanisms and related pathophysiologies contributing to these pain states. A key issue in pain medicine involves crucial events and mediators that contribute to normal and abnormal pain signaling, but remain unseen without genetic, biomarker or imaging analysis. Here we consider how the altered genetic make-up of familial pains reveals the human importance of channels discovered by preclinical research, followed by the contribution of receptors as stimulus transducers in cold sensing and cold pain. Finally we review recent data on the neuro-immune interactions in chronic pain and the potential targets for treatment in cancer-induced bone pain. PMID:23500200

Topical Treatment of Degenerative Knee Osteoarthritis.

This article reviews topical management strategies for degenerative osteoarthritis (OA) of the knee. A search of Pubmed, Embase and the Cochrane library using MeSH terms including "topical," "treatment," "knee" and "osteoarthritis" was carried out. Original research and review articles on the effectiveness and safety, recommendations from international published guidelines and acceptability studies of topical preparations were included. Current topical treatments included for the management of knee OA include topical nonsteroidal anti-inflammatory drugs, capsaicin, salicylates and physical treatments such as hot or cold therapy. Current treatment guidelines recommend topical nonsteroidal anti-inflammatory drugs as an alternative and even first-line therapy for OA management, especially among elderly patients. Guidelines on other topical treatments vary, from recommendations against their use, to in favor as alternative or simultaneous therapy, especially for patients with contraindications to other analgesics. Although often well-tolerated and preferred by many patients, clinical care still lags in the adoption of topical treatments. Aspects of efficacy, safety and patient quality of life data require further research. Copyright © 2018 Southern Society for Clinical Investigation. Published by Elsevier Inc. All rights reserved.

The patient perspective in research on major depression

Directory of Open Access Journals (Sweden)

Cuijpers Pim

2011-05-01

Full Text Available Abstract Although thousands of studies have examined the genetics, epidemiology, etiology, biology, treatment and prevention of major depressive disorder, we still lack very basic knowledge about what patients with depressive disorders need. Despite the thousands of studies that have been conducted on major depression and the hundreds of randomized trials that have examined the effects of treatments, many patients still do not know how to cope with the daily problems caused by depressive disorders. In this Commentary the need for more research on the perspectives of patients is described. This research should guide treatment studies as well as basic research much more than it currently does. This perpective is especially important to understand and solve the undertreatment of depression, one of the major problems in this area. Up to 50% of depressed patients do not seek treatment, resulting in huge avoidable disease burden and economic costs. In order to solve this problem we need a better understanding of the problems patients encounter in daily life, and what factors contribute to the reasons for seeking treatment or not. Research from the patients' perspective is also necessary to meet the currently unmet information needs of patients, including information about the nature and causes of depression, stigma, medication, treatment and coping with the daily problems of having depression.

2008-01-01

Cancer is currently a major public health problem and, as such, emerging research is making significant progress in identifying major players in its biology. One recent topic of interest involves microRNAs (miRNAs) which are small, non-coding RNA molecules that inhibit gene expression post-transcriptionally. They accomplish this by binding to the 3? untranslated region (3?UTR) of target messengerRNA (mRNA), resulting in either their degradation or inhibition of translation, depending on the d...

In 2016, 13 topics were selected as major research advances in gynecologic oncology. For ovarian cancer, study results supporting previous ones regarding surgical preventive strategies were reported. There were several targeted agents that showed comparable responses in phase III trials, including niraparib, cediranib, and nintedanib. On the contrary to our expectations, dose-dense weekly chemotherapy regimen failed to prove superior survival outcomes compared with conventional triweekly regimen. Single-agent non-platinum treatment to prolong platinum-free-interval in patients with recurrent, partially platinum-sensitive ovarian cancer did not improve and even worsened overall survival (OS). For cervical cancer, we reviewed robust evidences of larger-scaled population-based study and cost-effectiveness of nonavalent vaccine for expanding human papillomavirus (HPV) vaccine coverage. Standard of care treatment of locally advanced cervical cancer (LACC) was briefly reviewed. For uterine corpus cancer, new findings about appropriate surgical wait time from diagnosis to surgery were reported. Advantages of minimally invasive surgery over conventional laparotomy were reconfirmed. There were 5 new gene regions that increase the risk of developing endometrial cancer. Regarding radiation therapy, Post-Operative Radiation Therapy in Endometrial Cancer (PORTEC)-3 quality of life (QOL) data were released and higher local control rate of image-guided adaptive brachytherapy was reported in LACC. In addition, 4 general oncology topics followed: chemotherapy at the end-of-life, immunotherapy with reengineering T-cells, actualization of precision medicine, and artificial intelligence (AI) to make personalized cancer therapy real. For breast cancer, adaptively randomized trials, extending aromatase inhibitor therapy, and ribociclib and palbociclib were introduced. Copyright © 2017.

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.

Topical treatment of mild to moderate psoriasis is first-line treatment and exhibits varying degrees of success across patient groups. Key factors influencing treatment success are physician topical treatment choice (high efficacy, low adverse events) and strict patient adherence. Currently, no formalized, international consensus guidelines exist to direct optimal topical treatment, although many countries have national guidelines. To describe and analyse cross-regional variations in the use and access of psoriasis topical therapies. The study was conducted as an observational cross-sectional study. A survey was distributed to dermatologists from the International Psoriasis Council (IPC) to assess topical therapy accessibility in 26 countries and to understand how body surface area (BSA) categories guide clinical decisions on topical use. Variation in the availability of tars, topical retinoids, dithranol and balneotherapy was reported. The vast majority of respondents (100% and 88.4%) used topical therapy as first-line monotherapy in situations with BSA 10%, the number of respondents who prescribe topical therapy decreased considerably. In addition, combination therapy of a topical drug and a systemic drug was frequently reported when BSA measured >10%. This physician survey provides new evidence on topical access and the influence of disease severity on topical usage in an effort to improve treatment strategies on a global level. © 2017 European Academy of Dermatology and Venereology.

Most American colleges and universities offer gateway biology courses to meet the needs of three undergraduate audiences: biology and related science majors, many of whom will become biomedical researchers; premedical students meeting medical school requirements and preparing for the Medical College Admissions Test (MCAT); and students completing general education (GE) graduation requirements. Biology textbooks for these three audiences present a topic scope and sequence that correlates with the topic scope and importance ratings of the biology content specifications for the MCAT regardless of the intended audience. Texts for "nonmajors," GE courses appear derived directly from their publisher's majors text. Topic scope and sequence of GE texts reflect those of "their" majors text and, indirectly, the MCAT. MCAT term density of GE texts equals or exceeds that of their corresponding majors text. Most American universities require a GE curriculum to promote a core level of academic understanding among their graduates. This includes civic scientific literacy, recognized as an essential competence for the development of public policies in an increasingly scientific and technological world. Deriving GE biology and related science texts from majors texts designed to meet very different learning objectives may defeat the scientific literacy goals of most schools' GE curricula.

General practitioners frequently encounter skin diseases and are accustomed to diagnosing the most common dermatologic conditions. We sought to determine the most common dermatologic topics published in five high-impact general medical journals (New England Journal of Medicine, The Lancet, the Journal of the American Medical Association, British Medical Journal (now The BMJ), and Annals of Internal Medicine). We conducted an independent search of the Thomson Reuters’ Science Citation Index for common dermatologic topics, limited to the period 1970 to 2012. Total number of publications dealing with each dermatologic topic considered. The five most common dermatologic topics published were melanoma, psoriasis, herpes simplex, herpes zoster, and acne. Melanoma and psoriasis were the top two dermatologic topics published in each journal except for Annals of Internal Medicine. Internists frequently diagnose herpes simplex, herpes zoster, and acne, which are also common dermatologic topics published. Although internists infrequently diagnose melanoma and psoriasis, they are major topics for general medical journals because of their increased community awareness, major advancements in therapeutic research, and their nondermatologic manifestations.

Topical antibiotics as a major contextual hazard toward bacteremia within selective digestive decontamination studies: a meta-analysis.

Science.gov (United States)

Hurley, James C

2014-12-31

Among methods for preventing pneumonia and possibly also bacteremia in intensive care unit (ICU) patients, Selective Digestive Decontamination (SDD) appears most effective within randomized concurrent controlled trials (RCCT's) although more recent trials have been cluster randomized. However, of the SDD components, whether protocolized parenteral antibiotic prophylaxis (PPAP) is required, and whether the topical antibiotic actually presents a contextual hazard, remain unresolved. The objective here is to compare the bacteremia rates and patterns of isolates in SDD-RCCT's versus the broader evidence base. Bacteremia incidence proportion data were extracted from component (control and intervention) groups decanted from studies investigating antibiotic (SDD) or non-antibiotic methods of VAP prevention and summarized using random effects meta-analysis of study and group level data. A reference category of groups derived from purely observational studies without any prevention method under study provided a benchmark incidence. Within SDD RCCTs, the mean bacteremia incidence among concurrent component groups not exposed to PPAP (27 control; 17.1%; 13.1-22.1% and 12 intervention groups; 16.2%; 9.1-27.3%) is double that of the benchmark bacteremia incidence derived from 39 benchmark groups (8.3; 6.8-10.2%) and also 20 control groups from studies of non-antibiotic methods (7.1%; 4.8 - 10.5). There is a selective increase in coagulase negative staphylococci (CNS) but not in Pseudomonas aeruginosa among bacteremia isolates within control groups of SDD-RCCT's versus benchmark groups with data available. The topical antibiotic component of SDD presents a major contextual hazard toward bacteremia against which the PPAP component partially mitigates.

Multiple health behavior change (MHBC) approaches are understudied. The purpose of this study is to provide strategic MHBC research direction. This cross-sectional study contacted participants through the Society of Behavioral Medicine email listservs and rated the importance of 24 MHBC research topics (1 = not at all important, 5 = extremely important) separately for general and underserved populations. Participants (n = 76) were 79 % female; 76 % White, 10 % Asian, 8 % African American, 5 % Hispanic, and 1 % Native Hawaiian/Pacific Islander. Top MHBC research priorities were predictors of behavior change and the sustainability, long-term effects, and dissemination/translation of interventions for both populations. Recruitment and retention of participants (t(68) = 2.17, p = 0.000), multi-behavioral indices (t(68) = 3.54, p = 0.001), and measurement burden (t(67) = 5.04, p = 0.001) were important for the underserved. Results identified the same top research priorities across populations. For the underserved, research should emphasize recruitment, retention, and measurement burden.

John Gore’s seminal 1984 paper on gel dosimetry spawned a vibrant research field ranging from fundamental science through to clinical applications. A preliminary bibliometric study was undertaken of the gel dosimetry family of publications inspired by, and resulting from, Gore’s original 1984 paper to determine active growth areas, research trends and hot topics from Gore’s paper up to and including 2016. Themes and trends of the gel dosimetry research field were bibliometrically explored by way of co-occurrence term maps using the titles and abstracts text corpora from the Web of Science database for all relevant papers from 1984 to 2016. Visualisation of similarities was used by way of the VOSviewer visualisation tool to generate cluster maps of gel dosimetry knowledge domains and the associated citation impact of topics within the domains. Heat maps were then generated to assist in the understanding of active growth areas, research trends, and emerging and hot topics in gel dosimetry. (paper)

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.

Dutch energy policies from a European perspective. Major developments in 2003

ECN is not only active in technological research and development; it also plays a major role in policy research and development. Since national energy policy is increasingly influenced by developments at the European level and vice versa, ECN is shifting its attention from a national to a European focus. More and more, national energy and environmental policies are implemented within the framework of EU (European Union) directives, while reversibly the success of European policies is dependent on harmonised national actions in a liberalised European energy market. To demonstrate this shifting research orientation towards a European position ECN decided to highlight four major national topics that dominated policy discussions in the Netherlands during 2003 in this special publication. The first topic concerns changes in national renewable energy policy. Earlier policies had led to a dramatic increase in imports of renewable electricity with major fiscal consequences and it was decided to redress the balance towards stimulating domestic investment in renewable energy capacity. In the summer of 2003 extreme weather events led to an electricity supply crisis providing a short-term argument to look into the policy options for preventing shortages. The opportunities and limitations of demand side response to electricity supply shortages is the second topic addressed. Regarding climate change policies the most notable development undoubtedly concerns the impending implementation of a greenhouse gas emissions trading scheme. The focus in this chapter is on the interaction between the EU directive on emissions trading and the Dutch approach. As a relatively small country the Netherlands has always found it difficult to make appropriate energy research and development choices. During 2003 new directions in RD and D policies were determined. Apart from the optimal choice of nationally relevant research priorities, an additional vexing problem concerns the relative amounts of

Historical trends in a scientific field should be apparent in the changing content of journal articles over time. Using a topic modeling approach, a statistical method for quantifying the thematic content of text, 70 topics were extracted from the abstracts of 3,603 articles published in the Journal of Counseling Psychology from 1963 to 2015. After examining interpretability of 70 topics derived from the model, 64 meaningful topics and their trends were named. In addition, the authors also classified some of the related topics into 4 categories-counseling process and outcome, multiculturalism, research methodology, and vocational psychology. Counseling process and outcome related topics have decreased recently, while topics relating to multiculturalism and diversity have shown increasing trends. The authors also discussed trends that were observed and tried to account for the changing frequencies of some important research topics within these categories.

Average accuracy was rather low, but articles in quality newspapers were relatively more accurate than in popular and free newspapers. Our results provide specific recommendations for researchers and science communicators, to improve the translation of neuroscience findings through the media: 1 Caution is warranted during periods of heightened attention (news waves, as reporting tends to be more optimistic; 2 Caution is also warranted not to follow topic-related biases in optimism (e.g., development or skepticism (e.g., law; 3 Researchers should keep in mind that overall accuracy of reporting is low, and especially articles in popular and free newspapers provide a minimal amount of details.

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

Topic prominence in Chinese EFL learners’ interlanguage

Directory of Open Access Journals (Sweden)

Shaopeng Li

2014-01-01

Full Text Available The present study aims to investigate the general characteristics of topicprominent typological interlanguage development of Chinese learners of English in terms of acquiring subject-prominent English structures from a discourse perspective. Topic structures mainly appear in Chinese discourse in the form of topic chains (Wang, 2002; 2004. The research target are the topic chain, which is the main topic-prominent structure in Chinese discourse, and zero anaphora, which is the most common topic anaphora in the topic chain. Two important findings emerged from the present study. First, the characteristics of Chinese topic chains are transferrable to the interlanguage of Chinese EFL learners, thus resulting in overgeneralization of the zero anaphora. Second, the interlanguage discourse of Chinese EFL learners reflects a change of the second language acquisition process from topic-prominence to subject-prominence, thus lending support to the discourse transfer hypothesis.

Full Text Available Abstract Background Evidence mapping describes the quantity, design and characteristics of research in broad topic areas, in contrast to systematic reviews, which usually address narrowly-focused research questions. The breadth of evidence mapping helps to identify evidence gaps, and may guide future research efforts. The Global Evidence Mapping (GEM Initiative was established in 2007 to create evidence maps providing an overview of existing research in Traumatic Brain Injury (TBI and Spinal Cord Injury (SCI. Methods The GEM evidence mapping method involved three core tasks: 1. Setting the boundaries and context of the map: Definitions for the fields of TBI and SCI were clarified, the prehospital, acute inhospital and rehabilitation phases of care were delineated and relevant stakeholders (patients, carers, clinicians, researchers and policymakers who could contribute to the mapping were identified. Researchable clinical questions were developed through consultation with key stakeholders and a broad literature search. 2. Searching for and selection of relevant studies: Evidence search and selection involved development of specific search strategies, development of inclusion and exclusion criteria, searching of relevant databases and independent screening and selection by two researchers. 3. Reporting on yield and study characteristics: Data extraction was performed at two levels - 'interventions and study design' and 'detailed study characteristics'. The evidence map and commentary reflected the depth of data extraction. Results One hundred and twenty-nine researchable clinical questions in TBI and SCI were identified. These questions were then prioritised into high (n = 60 and low (n = 69 importance by the stakeholders involved in question development. Since 2007, 58 263 abstracts have been screened, 3 731 full text articles have been reviewed and 1 644 relevant neurotrauma publications have been mapped, covering fifty-three high priority

Parent Refusal of Topical Fluoride for Their Children: Clinical Strategies and Future Research Priorities to Improve Evidence-Based Pediatric Dental Practice.

Science.gov (United States)

Chi, Donald L

2017-07-01

A growing number of parents are refusing topical fluoride for their children during preventive dental and medical visits. This nascent clinical and public health problem warrants attention from dental professionals and the scientific community. Clinical and community-based strategies are available to improve fluoride-related communications with parents and the public. In terms of future research priorities, there is a need to develop screening tools to identify parents who are likely to refuse topical fluoride and diagnostic instruments to uncover the reasons for topical fluoride refusal. This knowledge will lead to evidence-based strategies that can be widely disseminated into clinical practice. Copyright © 2017 Elsevier Inc. All rights reserved.

Major hazards onshore and offshore

International Nuclear Information System (INIS)

1992-01-01

This symposium continues the tradition of bringing together papers on a topic of current interest and importance in terms of process safety - in this case, Major Hazards Onshore and Offshore. Lord Cullen in his report on the Piper Alpha disaster has, in effect, suggested that the experience gained in the control of major hazards onshore during the 1980s should be applied to improve safety offshore during the 1990s. This major three-day symposium reviews what has been learned so far with regard to major hazards and considers its present and future applications both onshore and offshore. The topics covered in the programme are wide ranging and deal with all aspects of legislation, the application of regulations, techniques for evaluating hazards and prescribing safety measures in design, construction and operation, the importance of the human factors, and recent technical developments in protective measures, relief venting and predicting the consequences of fires and explosions.

Assessment of β-lapachone loaded in lecithin-chitosan nanoparticles for the topical treatment of cutaneous leishmaniasis in L. major infected BALB/c mice.

Moreno, Esther; Schwartz, Juana; Larrea, Esther; Conde, Iosune; Font, Maria; Sanmartín, Carmen; Irache, Juan Manuel; Espuelas, Socorro

Patients affected by cutaneous leishmaniasis need a topical treatment which cures lesions without leaving scars. Lesions are produced not only by the parasite but also by an uncontrolled and persistent inflammatory immune response. In this study, we proposed the loading of β-lapachone (β-LP) in lecithin-chitosan nanoparticles (NP) for targeting the drug to the dermis, where infected macrophages reside, and promote wound healing. Although the loading of β-LP in NP did not influence the drug antileishmanial activity it was critical to achieve important drug accumulation in the dermis and permeation through the skin. When topically applied in Leishmania major infected BALB/c mice, β-LP NP achieved no parasite reduction but they stopped the lesion progression. Immuno-histopathological assays in CL lesions and quantitative mRNA studies in draining lymph nodes confirmed that β-LP exhibited anti-inflammatory activity leading to the down-regulation of IL-1β and COX-2 expression and a decrease of neutrophils infiltrate. Cutaneous leishmaniasis often leaves patients with unsightly scars due to the body's inflammatory response to the infection. The authors in this paper described topical treatment using β-lapachone (β- LP) loaded in lecithin-chitosan nanoparticles (NP) in an animal model. Results confirmed the reduction of inflammatory response without affecting the parasite killing efficacy. These findings would pave way for further clinical testing in the near future.

2011-01-01

Research interests in addressing construction and demolition (C and D) waste management issues have resulted in a large amount of publications during the last decade. This study demonstrates that there is no systematic examination on the research development in literature in the discipline of C and D waste management. This study presents the latest research trend in the discipline through analyzing the publications from 2000 to 2009 in eight major international journals. The analysis is conducted on the number of papers published annually, main authors' contributions, research methods and data analysis methods adopted, and research topics covered. The results exhibit an increasing research interest in C and D waste management in recent years. Researchers from developed economies have contributed significantly to the development of the research in the discipline. Some developing countries such as Malaysia and China have also been making good efforts in promoting C and D waste management research. The findings from this study also indicate that survey and case study are major methods for data collection, and the data are mostly processed through descriptive analysis. It is anticipated that more future studies on C and D waste management will be led by researchers from developing economies, where construction works will remain their major economic activities. On the other hand, more sophisticated modeling and simulating techniques have been used effectively in a number of studies on C and D waste management research, and this is considered a major methodology for future research in the discipline. C and D waste management will continue to be a hot research topic in the future, in particularly, the importance of human factors in C and D waste management has emerged as a new challenging topic.

2014-07-01

Full Text Available The present study aims to investigate the general characteristics of topic-prominent typological interlanguage development of Chinese learners of English in terms of acquiring subject-prominent English structures from the discourse perspective. We have selected as the research target “topic chain” which is the main topic-prominent structure in Chinese discourse and “zero anaphora” which is the most common topic anaphor of topic chain. Topic structures mainly appear in Chinese discourse in the form of “topic chain” (Wang, 2002; 2004. Actually, in the event of a topic chain, research on topic structures should go into the typical range of discourse. Two important findings were yielded by the present study. First, the characteristics of Chinese topic chain are transferrable to the interlanguage of Chinese EFL learners, thus resulting in overgeneralization of zero anaphora; second, interlanguage discourse of Chinese EFL learners reflects the characteristics of a second language acquisition process from topic-prominence to subject-prominence, thus lending support to the discourse transfer hypothesis.

Research trends on Big Data in Marketing: A text mining and topic modeling based literature analysis

Full Text Available Given the research interest on Big Data in Marketing, we present a research literature analysis based on a text mining semi-automated approach with the goal of identifying the main trends in this domain. In particular, the analysis focuses on relevant terms and topics related with five dimensions: Big Data, Marketing, Geographic location of authors’ affiliation (countries and continents, Products, and Sectors. A total of 1560 articles published from 2010 to 2015 were scrutinized. The findings revealed that research is bipartite between technological and research domains, with Big Data publications not clearly aligning cutting edge techniques toward Marketing benefits. Also, few inter-continental co-authored publications were found. Moreover, findings show that research in Big Data applications to Marketing is still in an embryonic stage, thus making it essential to develop more direct efforts toward business for Big Data to thrive in the Marketing arena.

In 2008, the Ministry of Health, Welfare and Sport commissioned the National Care for the Elderly Programme. While numerous research projects in older persons' health care were to be conducted under this national agenda, the Programme further advocated the development of The Older Persons and Informal Caregivers Survey Minimum DataSet (TOPICS-MDS) which would be integrated into all funded research protocols. In this context, we describe TOPICS data sharing initiative (www.topics-mds.eu). A working group drafted TOPICS-MDS prototype, which was subsequently approved by a multidisciplinary panel. Using instruments validated for older populations, information was collected on demographics, morbidity, quality of life, functional limitations, mental health, social functioning and health service utilisation. For informal caregivers, information was collected on demographics, hours of informal care and quality of life (including subjective care-related burden). Between 2010 and 2013, a total of 41 research projects contributed data to TOPICS-MDS, resulting in preliminary data available for 32,310 older persons and 3,940 informal caregivers. The majority of studies sampled were from primary care settings and inclusion criteria differed across studies. TOPICS-MDS is a public data repository which contains essential data to better understand health challenges experienced by older persons and informal caregivers. Such findings are relevant for countries where increasing health-related expenditure has necessitated the evaluation of contemporary health care delivery. Although open sharing of data can be difficult to achieve in practice, proactively addressing issues of data protection, conflicting data analysis requests and funding limitations during TOPICS-MDS developmental phase has fostered a data sharing culture. To date, TOPICS-MDS has been successfully incorporated into 41 research projects, thus supporting the feasibility of constructing a large (>30,000 observations

Fusion research in Hungary

International Nuclear Information System (INIS)

Zoletnik, S.

2004-01-01

Hungarian fusion research started in the 1970s, when the idea of installing a small tokamak experiment emerged. In return to computer equipment a soviet tokamak was indeed sent to Hungary and started to operate as MT-1 at the Central Research Institute for Physics (KFKI) in 1979. Major research topics included diagnostic development, edge plasma studies and investigation of disruptions. Following a major upgrade in 1992 (new vacuum vessel, active position control and PC network based data acquisition system) the MT-1M tokamak was used for the study of transport processes with trace impurity injection, micropellet ablation studies, X-ray tomography and laser blow-off diagnostic development. Although funding ceased in the middle of the 90's the group was held alive by collaborations with EU fusion labs: FZ -Juelich, IPP-Garching and CRPP-EPFL Lausanne. In 1998 the machine was dismantled due to reorganization of the Hungarian Academy of Sciences. New horizons opened to fusion research from 1999, when Hungary joined EURATOM and a fusion Association was formed. Since then fusion physics studies are done in collaboration with major EU fusion laboratories, Hungarian researchers also play an active role in JET diagnostics upgrade and ITER design. Major topics are pellet ablation studies, plasma turbulence diagnosis using Beam Emission Spectroscopy and other techniques, tomography and plasma diagnostics using various neutral beams. In fusion relevant technology R and D Hungary has less records. Before joining EURATOM some materials irradiation studies were done at the Budapest Research Reactor at KFKI-AEKI. The present day fusion technology programme focuses still on irradiation studies, nuclear material database and electromagnetic testing techniques. Increasing the fusion technology research activities is a difficult task, as the competition in Hungarian industry is very strong and the interest of organizations in long-term investments into R and D is rather weak and

Nano-enabled drug delivery (NEDD) systems are rapidly emerging as a key area for nanotechnology application. Understanding the status and developmental prospects of this area around the world is important to determine research priorities, and to evaluate and direct progress. Global research publication and patent databases provide a reservoir of information that can be tapped to provide intelligence for such needs. Here, we present a process to allow for extraction of NEDD-related information from these databases by involving topical experts. This process incorporates in-depth analysis of NEDD literature review papers to identify key subsystems and major topics. We then use these to structure global analysis of NEDD research topical trends and collaborative patterns, inform future innovation directions. This paper describes the process of how to derive nano-enabled drug delivery-related information from global research and patent databases in an effort to perform comprehensive global analysis of research trends and directions, along with collaborative patterns.

1979-01-01

Ten search profiles are tested on the INIS system at the Japan Atomic Energy Research Institute. The results are plotted on recall-precision chart ranging from 100% recall to 100% precision. The curves are not purely systems-dependent nor search-dependent, and are determined substantially by the ''affinity'' between the system and the search topic. The curves are named ''Affinity curves of search topics with information retrieval systems'', and hence retrieval affinity factors are derived. They are obtained not only for individual search topics but also for averages in the system. By such a quantitative examination, the difference of affinity among search topics in a given system, that of the same search topic among various systems, and that of systems to the same group of search topics can be compared reasonably.

EvoRiver: Visual Analysis of Topic Coopetition on Social Media.

Sun, Guodao; Wu, Yingcai; Liu, Shixia; Peng, Tai-Quan; Zhu, Jonathan J H; Liang, Ronghua

2014-12-01

Cooperation and competition (jointly called "coopetition") are two modes of interactions among a set of concurrent topics on social media. How do topics cooperate or compete with each other to gain public attention? Which topics tend to cooperate or compete with one another? Who plays the key role in coopetition-related interactions? We answer these intricate questions by proposing a visual analytics system that facilitates the in-depth analysis of topic coopetition on social media. We model the complex interactions among topics as a combination of carry-over, coopetition recruitment, and coopetition distraction effects. This model provides a close functional approximation of the coopetition process by depicting how different groups of influential users (i.e., "topic leaders") affect coopetition. We also design EvoRiver, a time-based visualization, that allows users to explore coopetition-related interactions and to detect dynamically evolving patterns, as well as their major causes. We test our model and demonstrate the usefulness of our system based on two Twitter data sets (social topics data and business topics data).

A brief review is presented of fundamental research topics of primary importance to the development of improved solar cells based on chalcopyrite-structure materials. The opinions presented are a consensus opinion of the authors of the paper, with input from members of the chalcopyrite solar cells research community in the United States. Major topical areas identified included, in order of importance, are (1) development of an integrated predictive understanding of CIGS(S) materials and devices, (2) development of novel deposition techniques and characterization of the mechanisms of growth in existing and novel processes, (3) novel materials, especially with wide-energy gaps (is greater than or equal to 1.7 eV) other than Cu-based chalcopyrites, (4) development of real-time material characterizations for process control, and (5) alternative front- and rear-contact materials. Although the five topics identified are quite broad, they do not include all topics of interest. Also discussed briefly are some other potential research areas not in the highest priority topics, in particular, areas identified as primarily ''engineering'' rather than ''science.''

1986-11-01

The multidisciplinary project was initiated in fiscal year 1986. It comprises two major interrelated parts: (1) Technical Assistance. This part of the project includes: (a) review of the progress of major projects in the DOE Office of Civilian Radioactive Waste Management Program and advise the Engineering and Geotechnology Division on significant technical issues facing each project; (b) analyze geotechnical data, reports, tests, surveys and plans for the different projects; (c) review and comment on major technical reports and other program documents such as site characterization plans and area characterization plans and (d) provide scientific and technical input at technical meetings. (2) Topical Studies. This activity comprises studies on scientific and technical topics, and issues of significance to in-situ testing, test analysis methods, and performance assessment of nuclear waste geologic repositories. The subjects of study were selected based on discussions with DOE staff. For fiscal year 1986, one minor and one major area of investigation were undertaken. The minor topic is a preliminary consideration and planning exercise for post-closure monitoring studies. The major topic, with subtasks involving various geoscience disciplines, is on the mechanical, hydraulic, geophysical and geochemical properties of fractures in geologic rock masses. The present report lists the technical reviews and comments made during the fiscal year and summarizes the technical progress of the topical studies

Human memory research: Current hypotheses and new perspectives

Directory of Open Access Journals (Sweden)

Antônio Jaeger

Full Text Available Abstract Research on human memory has increased significantly in the last few decades. Inconsistencies and controversies inherent to such research, however, are rarely articulated on published reports. The goal of the present article is to present and discuss a series of open questions related to major topics on human memory research that can be addressed by future research. The topics covered here are visual working memory, recognition memory, emotion and memory interaction, and methodological issues of false memories studies. Overall, the present work reveals a series of open questions and alternative analysis which could be useful for the process of hypothesis generation, and consequently for the design and implementation of future research on human memory.

With the rapid accumulation of biological datasets, machine learning methods designed to automate data analysis are urgently needed. In recent years, so-called topic models that originated from the field of natural language processing have been receiving much attention in bioinformatics because of their interpretability. Our aim was to review the application and development of topic models for bioinformatics. This paper starts with the description of a topic model, with a focus on the understanding of topic modeling. A general outline is provided on how to build an application in a topic model and how to develop a topic model. Meanwhile, the literature on application of topic models to biological data was searched and analyzed in depth. According to the types of models and the analogy between the concept of document-topic-word and a biological object (as well as the tasks of a topic model), we categorized the related studies and provided an outlook on the use of topic models for the development of bioinformatics applications. Topic modeling is a useful method (in contrast to the traditional means of data reduction in bioinformatics) and enhances researchers' ability to interpret biological information. Nevertheless, due to the lack of topic models optimized for specific biological data, the studies on topic modeling in biological data still have a long and challenging road ahead. We believe that topic models are a promising method for various applications in bioinformatics research.

Topical infections, involving a number of diseases such as impetigo, eczema, pustular acne, psoriasis and infected seborrheic dermatitis are one among the many challenges to health which stand out for their profound impact on human species. The treatment of topical infections has always been a difficult proposition because of the lack of efficacy of existing anti-infectives, longer period of treatment and yet incomplete recovery. The increasing emergence of antibiotic resistant bacterial strains like Staphylococcus aureus, Methicillin-Resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa undermine the need of development of new delivery systems to enhance the therapeutic efficacy of existing topical anti-infectives. The application of nanotechnology to medicine, or nanomedicine, is rapidly becoming a major driving force behind ongoing changes in the anti-infective field because of its interaction at the sub-atomic level with the skin tissue. The latter, in the current scenario, points towards vesicular carriers like liposomes, lipidic nanoparticles and silver nanoparticles etc. as the most promising drug delivery solutions for topical infection disorders. These have exhibited immense significance owing to their uniqueness to facilitate the interactions at interfaces with the barrier membranes. The present review summarizes the emerging efforts in combating topical infections particularly using nanomedicine based delivery systems as new tools to tackle the current challenges in treating infectious diseases. Besides, compiling various research reports, this article also includes formulation considerations, mechanisms of penetration and patents reported. Despite the new emerging technologies and delivery systems, efforts are still needed in the right direction to combat this global challenge.

What can we learn from corporate sustainability reporting? Deriving propositions for research and practice from over 9,500 corporate sustainability reports published between 1999 and 2015 using topic modelling technique.

Science.gov (United States)

Székely, Nadine; Vom Brocke, Jan

2017-01-01

Organizations are increasingly using sustainability reports to inform their stakeholders and the public about their sustainability practices. We apply topic modelling to 9,514 sustainability reports published between 1999 and 2015 in order to identify common topics and, thus, the most common practices described in these reports. In particular, we identify forty-two topics that reflect sustainability and focus on the coverage and trends of economic, environmental, and social sustainability topics. Among the first to analyse such a large amount of data on organizations' sustainability reporting, the paper serves as an example of how to apply natural language processing as a strategy of inquiry in sustainability research. The paper also derives from the data analysis ten propositions for future research and practice that are of immediate value for organizations and researchers.

The Cochrane Collaboration aims to produce relevant and top priority evidence that responds to existing evidence gaps. Hence, research priority setting (RPS) is important to identify which potential research gaps are deemed most important. Moreover, RPS supports future health research to conform both health and health evidence needs. However, studies that are prioritising systematic review topics in public health are surprisingly rare. Therefore, to inform the research agenda of Cochrane Public Health Europe (CPHE), we introduce the protocol of a priority setting study on systematic review topics in several European countries, which is conceptualised as pilot. We will conduct a two-round modified Delphi study in Switzerland, incorporating an anonymous web-based questionnaire, to assess which topics should be prioritised for systematic reviews in public health. In the first Delphi round public health stakeholders will suggest relevant assessment criteria and potential priority topics. In the second Delphi round the participants indicate their (dis)agreement to the aggregated results of the first round and rate the potential review topics with the predetermined criteria on a four-point Likert scale. As we invite a wide variety of stakeholders we will compare the results between the different stakeholder groups. We have received ethical approval from the ethical board of the University of Bremen, Germany (principal investigation is conducted at the University of Bremen) and a certificate of non-objection from the Canton of Zurich, Switzerland (fieldwork will be conducted in Switzerland). The results of this study will be further disseminated through peer reviewed publication and will support systematic review author groups (i.a. CPHE) to improve the relevance of the groups´ future review work. Finally, the proposed priority setting study can be used as a framework by other systematic review groups when conducting a priority setting study in a different context. �

Telescopic Topics: The Impact of Student-Created Podcasts in a Large, General Education Course

Science.gov (United States)

Kraal, E. R.

2014-12-01

Large, general education courses are important to the geoscience community. These courses serve as valuable recruiting tools for future geoscience majors because over 55% of geoscience students select their major in the first two years of college (Wilson, 2013). These courses can have many challenges such as large class sizes, limited (or no) laboratory time and facilities, little financial resource support, non-permanent faculty, and a variety of student abilities and needs. High impact practices, such as writing courses, student research, and community service can be difficult to integrate into large, non-major courses. Student-produced audio (e. g. podcasts) provide one approach to providing high impact practices within these courses. Other researchers have found student produced audio to be effective at transmitting content, integrating place based experiences, and building community connections within the students. Here I present the implementation of student-created audio within a large (100+), general education course (AST 30 - Mission to the Planets) over the last 4 years called 'Telescopic Topics.' Activities scaffold the students through the semester where they select a topic on planetary science, work with the science reference librarian, visit the writing center, and record their podcast at campus student radio station. The top podcasts are then aired on the campus radio station during the news broadcasts through a rotating series. Surveys of student experiences find that student find the activity valuable and engaging. Students reported feeling less intimidated by the science content and more connected to the subject matter. In addition, it provides many of them with their first introduction to and use of the university library and associated campus resources.

Interactional Organization and Topic Control in Conciliation Hearings

Wânia Terezinha Ladeira

2011-07-01

Full Text Available We analyse discursive topic in talk-in-interaction within the institutional setting of three conciliation hearings held in a kind of small claims court for consumption conflict resolution. This research is based on Interactional Sociolinguistics and Conversation Analysis theories. The analysis shows that the participants of those meetings have asymmetric rights regarding the choice of discussion topics. Thus, the mediator is the one who has the right to suggest and control the discursive topics of the conversation. This topic control is the most important institutional procedure that can cause a reduction in accusations and adjacent replies. Consequently, the chance of mediators achieving their institutional task of reaching an agreement between parts in conflict is increased.

In the review article by Kopsky and Stahl, four critical barriers in the process of research and development of topical analgesics were indicated. The active pharmaceutical ingredient (API and the formulation are among the major challenges. The road to the development of such drugs passes through preclinical studies. These studies, if planned correctly, should serve as guidance for choosing the right API and formulation. Although rodent models for pain continue to provide valuable data on the mechanisms driving pain, their use in developing topical and localized treatment approaches is limited for technical (intraplate injection area is small as well as mechanical reasons (non-similarity to human skin and innervation. It has been previously shown that pigs are comparable to humans in ways that make them a better choice for evaluating topical and local analgesics. The aim of this study was to summarize several experiments that used pigs for testing postoperative pain in an incisional pain model (skin incision [SI] and skin and muscle incision [SMI]. At the end of the surgery, the animals were treated with different doses of bupivacaine solution (Marcaine®, bupivacaine liposomal formulation (Exparel® or ropivacaine solution (Naropin. Von Frey testing demonstrated a decrease in the animals’ sensitivity to mechanical stimulation expressed as an increase in the withdrawal force following local treatment.

Topics on continua

CERN Document Server

2005-01-01

Specialized as it might be, continuum theory is one of the most intriguing areas in mathematics. However, despite being popular journal fare, few books have thoroughly explored this interesting aspect of topology. In Topics on Continua, Sergio Macías, one of the field's leading scholars, presents four of his favorite continuum topics: inverse limits, Jones's set function T, homogenous continua, and n-fold hyperspaces, and in doing so, presents the most complete set of theorems and proofs ever contained in a single topology volume. Many of the results presented have previously appeared only in research papers, and some appear here for the first time. After building the requisite background and exploring the inverse limits of continua, the discussions focus on Professor Jones''s set function T and continua for which T is continuous. An introduction to topological groups and group actions lead to a proof of Effros''s Theorem, followed by a presentation of two decomposition theorems. The author then offers an...

For doing research on topics in primary care medicine participation of primary care physicians is necessary. Research in this field of medicine is only marginally established in Switzerland. In a postal survey we evaluate the general attitudes of physicians towards research in the field of primary care. In particular we were interested in their willingness to participate in research projects and the facilitating and impeding factors to take part in such projects. A purpose designed questionnaire was sent by post to 3044 primary care physicians in the central and eastern parts of Switzerland. The return rate was 52%. A majority of 94% of the responding physicians revealed interest in primary care research and 60% of all responders are willing to participate actively in such projects. They are prepared to spend about 15 min a day for data acquisition. Their willingness to participate depends on the conditions that, first, the research topic is relevant for daily practice and, second, boards odder Continuous Medical Education credits for time spent for research. Time constraints, additional administrative work and lack of relevance of research topics to daily practice are the main barriers. This survey demonstrates the general interest of primary care physicians to participate in relevant research projects. Therefore the structure to set up such research should be established.

Full Text Available Objectives: To analyze multi-source data including awards, publications, patents and drugs, and try to draw the whole landscape of the research and development community in the area of natural products (NPs against cancer. Materials and Methods: Awards, publications, patents and drugs data from National Institute of Health/Natural Science Foundation of China (NIH/NSFC, PubMed, Derwent Innovation Index and Cortellis were collected. Bibliometric methodologies and technology are used to investigate publications/patents/drugs, their contents and relationships. Results: NIH and NSFC respectively demonstrated a stable and sustained expenditure growth in this area. The number of publications is continuously increasing. Yet the annual patent applications worldwide and FDA drug approvals were little changed or not obviously fluctuated in 2003-2013. USA and several Asia-pacific countries/territories are important contributing powers. We described the evolution of major research topics by those MeSH Major Topics indexed in PubMed with the largest growth range in three intervals, and analyzed hot research topics in the recent 10 years which include NPs or NPs derivatives, cell line/animal model, laboratory technologies and activation mechanisms. Conclusions: China published the most publications and received the most patent applications, but drug discovery performance is no better than USA and Japan. Research on anti-neoplastic structures and compounds originated from Chinese traditional medicine (TCM, medicinal plants, herbal medicine and marine NPs are major research topics in the recent 10 years. There still exits translational gap between basic research and drug discovery. Translational research should be undertaken to strengthen the applicability of NPs.

2016-01-01

This review provides the first comprehensive overview of the use of both nanoparticles and nanofibers for topical drug delivery. Researchers have explored the use of nanotechnology, specifically nanoparticles and nanofibers, as drug delivery systems for topical and transdermal applications. This approach employs increased drug concentration in the carrier, in order to increase drug flux into and through the skin. Both nanoparticles and nanofibers can be used to deliver hydrophobic and hydrophilic drugs and are capable of controlled release for a prolonged period of time. The examples presented provide significant evidence that this area of research has—and will continue to have — a profound impact on both clinical outcomes and the development of new products.

Pediatric obesity is a world-wide challenge. Children with physical disabilities are particularly at risk of obesity, which is worrisome because obesity can result in serious secondary conditions that decrease health status, reduce independence, and increase impact on healthcare systems. However, the determinants of obesity and the health promotion needs of children with physical disabilities are relatively unexplored compared with their typically developing peers. This white paper describes a Canadian multi-stakeholder workshop on the topic of obesity and health in children with physical disabilities and provides recommendations for future research in this understudied area. Seventy-one knowledge gaps identified by attendees using a modified nominal group technique clustered into six themes: (1) early, sustained engagement of families; (2) rethinking determinants of obesity and health; (3) maximizing impact of research; (4) inclusive integrated interventions; (5) evidence-informed measurement and outcomes; and (6) reducing weight biases. Attendees worked together to develop research plans in more detail for three areas identified through consensus as high priority: "early, sustained engagement of families;" "rethinking determinants of obesity and health;" and "evidence informed measurement and outcomes." Using the workshop described here as a call to action, Canadian researchers are now well positioned to work toward a greater understanding of weight-related topics in children with physical disabilities, with the aim of developing evidence-based and salient obesity prevention and treatment approaches.

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.

It is thought that the science of ecology has experienced conceptual shifts in recent decades, chiefly from viewing nature as static and balanced to a conception of constantly changing, unpredictable, complex ecosystems. Here, we ask if these changes are reflected in actual ecological research over the last 30 years. We surveyed 750 articles from the entire pool of ecological literature and 750 articles from eight leading journals. Each article was characterized according to its type, ecological domain, and applicability, and major topics. We found that, in contrast to its common image, ecology is still mostly a study of single species (70% of the studies); while ecosystem and community studies together comprise only a quarter of ecological research. Ecological science is somewhat conservative in its topics of research (about a third of all topics changed significantly through time), as well as in its basic methodologies and approaches. However, the growing proportion of problem-solving studies (from 9% in the 1980s to 20% in the 2000 s) may represent a major transition in ecological science in the long run.

Topical anti-infective sinonasal irrigations: update and literature review.

Lee, Jivianne T; Chiu, Alexander G

2014-01-01

Sinonasal anti-infective irrigations have emerged as a promising therapeutic modality in the comprehensive management of chronic rhinosinusitis (CRS), particularly in the context of recalcitrant disease. The purpose of this article was to delineate the current spectrum of topical anti-infective therapies available and evaluate their role in the treatment of CRS. A systematic literature review was performed on all studies investigating the use of topical antimicrobial solutions in the medical therapy of CRS. Anti-infective irrigations were stratified into topical antibacterial, antifungal, and additive preparations according to their composition and respective microbicidal properties. The use of topical antibiotic irrigations has been supported by low-level studies in the treatment of refractory CRS, with optimal results achieved in patients who have undergone prior functional endoscopic sinus surgery and received culture-directed therapy. Multiple evidence-based reviews have not established any clinical benefit with the administration of topical antifungals, and their use is not currently recommended in the management of routine CRS. Topical additives including surfactants may be beneficial as adjunctive treatment for recalcitrant CRS, but additional research is needed to investigate their efficacy in comparison with other agents and establish safety profiles. Topical anti-infective solutions are not recommended as first-line therapy for routine CRS but may be considered as a potential option for patients with refractory CRS who have failed traditional medical and surgical intervention. Additional research is necessary to determine which patient populations would derive the most benefit from each respective irrigation regimen and identify potential toxicities associated with prolonged use.

Gunn, John S; Ledford, Cynthia H; Mousetes, Steven J; Grever, Michael R

2018-01-01

Many students entering professional degree programs, particularly M.D., Ph.D., and M.D./Ph.D., are not well prepared regarding the breadth of scientific knowledge required, communication skills, research experience, reading and understanding the scientific literature, and significant shadowing (for M.D.-related professions). In addition, physician scientists are a needed and necessary part of the academic research environment but are dwindling in numbers. In response to predictions of critical shortages of clinician investigators and the lack of proper preparation as undergraduates for these professions, the Biomedical Science (BMS) undergraduate major was created at The Ohio State University to attract incoming college freshmen with interests in scientific research and the healthcare professions. The intent of this major was to graduate an elite cohort of highly talented individuals who would pursue careers in the healthcare professions, biomedical research, or both. Students were admitted to the BMS major through an application and interview process. Admitted cohorts were small, comprising 22 to 26 students, and received a high degree of individualized professional academic advising and mentoring. The curriculum included a minimum of 4 semesters (or 2 years) of supervised research experience designed to enable students to gain skills in clinical and basic science investigation. In addition to covering the prerequisites for medicine and advanced degrees in health professions, the integrated BMS coursework emphasized research literacy as well as skills related to work as a healthcare professional, with additional emphasis on independent learning, teamwork to solve complex problems, and both oral and written communication skills. Supported by Ohio State's Department of Internal Medicine, a unique clinical internship provided selected students with insights into potential careers as physician scientists. In this educational case report, we describe the BMS

Richins, William; Novascone, Stephen; O'Brien, Cheryl

2009-01-01

The Idaho National Laboratory (INL, USA) and IASMiRT sponsored an international forum Nov 5-6, 2008 in Porvoo, Finland for nuclear industry, academic, and regulatory representatives to identify structural issues in current and future advanced reactor design, especially for extreme conditions and external threats. The purpose of this Topical Workshop was to articulate research, engineering, and regulatory Code development needs. The topics addressed by the Workshop were selected to address critical industry needs specific to advanced reactor structures that have long lead times and can be the subject of future SMiRT technical sessions. The topics were; (1) structural/materials needs for extreme conditions and external threats in contemporary (Gen. III) and future (Gen. IV and NGNP) advanced reactors and (2) calibrating simulation software and methods that address topic 1. The workshop discussions and research needs identified are presented. The Workshop successfully produced interactive discussion on the two topics resulting in a list of research and technology needs. It is recommended that IASMiRT communicate the results of the discussion to industry and researchers to encourage new ideas and projects. In addition, opportunities exist to retrieve research reports and information that currently exists, and encourage more international cooperation and collaboration. It is recommended that IASMiRT continue with an off-year workshop series on select topics.

Plant invasions in China: an emerging hot topic in invasion science

Directory of Open Access Journals (Sweden)

Jian Liu

2012-12-01

Full Text Available China has shown a rapid economic development in recent decades, and several drivers of this change are known to enhance biological invasions, a major cause of biodiversity loss. Here we review the current state of research on plant invasions in China by analyzing papers referenced in the ISI Web of Knowledge. Since 2001, the number of papers has increased exponentially, indicating that plant invasions in China are an emerging hot topic in invasion science. The analyzed papers cover a broad range of methodological approaches and research topics. While more that 250 invasive plant species with negative impacts have been reported from China, only a few species have been considered in more than a handful of papers (in order of decreasing number of references: Spartina alterniflora, Ageratina adenophora, Mikania micrantha, Alternanthera philoxeroides, Solidago canadensis, Eichhornia crassipes. Yet this selection might rather reflect the location of research teams than the most invasive plant species in China. Considering the previous achievements in China found in our analysis research in plant invasions could be expanded by (1 compiling comprehensive lists of non-native plant species at the provincial and national scales and to include species that are native to one part of China but non-native to others in these lists; (2 strengthening pathways studies (primary introduction to the country, secondary releases within the country to enhance prevention and management; and (3 assessing impacts of invasive species at different spatial scales (habitats, regions and in relation to conservation resources.

2001-07-01

Motivating nonscience majors in science and mathematics studies became one of the most interesting and important challenges in contemporary science and mathematics education. Therefore, designing and studying a learning environment, which enhances students' motivation, is an important task. This experimental study sought to explore the implications of student autonomy in topic choice in a project-based Physical Science Course for nonscience majors' on students' motivational orientation. It also suggested and tested a model explaining motivational outcomes of project-based learning environment through increased student ownership of science projects. A project, How Things Work, was designed and implemented in this study. The focus of the project was application of physical science concepts learned in the classroom to everyday life situations. Participants of the study (N = 59) were students enrolled in three selected sections of a Physical Science Course, designed to fulfill science requirements for nonscience majors. These sections were taught by the same instructor over a period of an entire 16-week semester at a large public research university. The study focused on four main variables: student autonomy in choosing a project topic, their motivational orientation, student ownership of the project, and the interest in the project topic. Achievement Goal Orientation theory became the theoretical framework for the study. Student motivational orientation, defined as mastery or performance goal orientation, was measured by an Achievement Goal Orientation Questionnaire. Student ownership was measured using an original instrument, Ownership Measurement Questionnaire, designed and tested by the researchers. Repeated measures yoked design, ANOVA, ANCOVA, and multivariate regression analysis were implemented in the study. Qualitative analysis was used to complement and verify quantitative results. It has been found that student autonomy in the project choice did not make a

Ageing management of nuclear power plant concrete structures - Overview and suggested research topics

International Nuclear Information System (INIS)

Naus, J.

2009-01-01

Nuclear power plant concrete structures are described and their operating experience noted. Primary considerations related to management of their ageing are noted and an indication of their status provided: degradation mechanisms, damage models, and material performance; assessment and remediation (i.e., component selection, in-service inspection, non-destructive examinations, and remedial actions); and estimation of performance at present or some future point in time (i.e., application of structural reliability theory to the design and optimisation of in-service inspection/maintenance strategies, and determination of the effects of degradation on plant risk). Several activities are identified that provide background information and data on areas of concern with respect to non-destructive examination of nuclear power plant concrete structures: inspection of thick-walled, heavily-reinforced sections; basemat; and inaccessible areas of the containment metallic pressure boundary. Topics are noted where additional research would be of benefit to ageing management of nuclear power plant concrete structures. (author)

Lin, Huey-Ya; Davidman, Patricia; Petersen, George; Thomas, R. Murray

1998-01-01

In a questionnaire survey, 94 teachers in Taiwan and 140 in the United States judged which topics among 20 moral issues would be appropriate subjects of study in grade six of the primary school and in the first year of the university. The issues related to religion, ethnicity, gender, health care, crime, alcohol, tobacco, gambling, guns, government corruption, birth control, caring for the elderly, and television programming. The results revealed great diversity of opinion within each group of respondents. No single topic was approved by all teachers in either group, nor was any topic rejected by all. Among the 234 teachers, no two offered precisely the same configuration of answers over the 20 topics. Nevertheless, some group trends could be identified for individual topics. For example, in both countries the great majority of respondents would teach about industrial pollution, whereas very few would approve of trying to identify the best religion. In the rationales teachers offered in support of their choices, the four reasons that figured most prominently in both countries were that a topic would contribute to the nation's welfare, would help students to make wise decisions, would be interesting for students, and would represent a peaceful way to face social problems.

Science.gov (United States)

Patel, Viral; Sharma, Om Prakash; Mehta, Tejal

2018-04-01

Skin is an important route of drug delivery for the treatment of various dermatological conditions. The advent of nanotechnology is paving the roadmaps for topical drug delivery by providing sustained release as well as maintaining a localized effect, outweighing the toxicity concern. Area covered: This review highlighted the morphology of skin, its barrier nature as well as drug penetration pathways after topical application of formulations. The existing methods to improve topical drug delivery, by infringing or permeating the skin barriers, are discussed. This context concretes the foundation to accentuate the need for the development of nanocrystal-based topical formulation. The mechanism of drug release, immediate as well as sustained release, after topical administration of drug nanocrystals is also elaborated. The special emphasis is given on the breakthrough achieved, in topical drug delivery using drug nanocrystals, so far in the plethora of literature, patents, and products, under clinical trial as well as in the market. Expert opinion: The current research on nanocrystals for topical drug delivery is highlighting the breakthroughs achieved so far. The output of these research envisages that topical nanocrystals based formulations can be a novel strategy for the drugs which are facing solubility, bioavailability and toxicity concerns.

Topics in Current Science Research (TCSR) is a five-week summer course offered at the University of California, Berkeley through a collaboration between the Level Playing Field Institute's Summer Math and Science Honors Academy (SMASH) Program and the Cryogenic Dark Matter Search (CDMS) group at UC Berkeley. 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.

Getting Started with Topic Modeling and MALLET

Directory of Open Access Journals (Sweden)

Shawn Graham

2012-09-01

Full Text Available In this lesson you will first learn what topic modeling is and why you might want to employ it in your research. 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.

Topic modeling for cluster analysis of large biological and medical datasets.

Science.gov (United States)

Zhao, Weizhong; Zou, Wen; Chen, James J

2014-01-01

The big data moniker is nowhere better deserved than to describe the ever-increasing prodigiousness and complexity of biological and medical datasets. New methods are needed to generate and test hypotheses, foster biological interpretation, and build validated predictors. Although multivariate techniques such as cluster analysis may allow researchers to identify groups, or clusters, of related variables, the accuracies and effectiveness of traditional clustering methods diminish for large and hyper dimensional datasets. Topic modeling is an active research field in machine learning and has been mainly used as an analytical tool to structure large textual corpora for data mining. Its ability to reduce high dimensionality to a small number of latent variables makes it suitable as a means for clustering or overcoming clustering difficulties in large biological and medical datasets. In this study, three topic model-derived clustering methods, highest probable topic assignment, feature selection and feature extraction, are proposed and tested on the cluster analysis of three large datasets: Salmonella pulsed-field gel electrophoresis (PFGE) dataset, lung cancer dataset, and breast cancer dataset, which represent various types of large biological or medical datasets. All three various methods are shown to improve the efficacy/effectiveness of clustering results on the three datasets in comparison to traditional methods. A preferable cluster analysis method emerged for each of the three datasets on the basis of replicating known biological truths. Topic modeling could be advantageously applied to the large datasets of biological or medical research. The three proposed topic model-derived clustering methods, highest probable topic assignment, feature selection and feature extraction, yield clustering improvements for the three different data types. Clusters more efficaciously represent truthful groupings and subgroupings in the data than traditional methods, suggesting

Garg, Tarun; Rath, Goutam; Goyal, Amit K

2015-12-01

Skin is the largest organ of the human body and plays the most important role in protecting against pathogen and foreign matter. Three important modes such as topical, regional and transdermal are widely used for delivery of various dosage forms. Among these modes, the topical dosage forms are preferred because it provides local therapeutic activity when applied to the skin or mucous membranes. Additives or pharmaceutical excipients (non-drug component of dosage form) are used as inactive ingredients in dosage form or tools for structuring dosage forms. The main use of topical dosage form additives are controling the extent of absorption, maintaining the viscosity, improving the stability as well as organoleptic property and increasing the bulk of the formulation. The overall goal of this article is to provide the clinician with information related to the topical dosage form additives and their current major applications against various diseases.

Influence of number of topics, topic duration, and curricular focus on biology achievement of Population 3 TIMSS countries

Science.gov (United States)

Hodges, Eddie Louis

The purposes of this study were to determine if a relationship exists between biology achievement and (1) number of topics, (2) topic duration, (3) curricular focus, and (4) science achievement using TIMSS data from Population 3---the final year of secondary school. Students included in this study were subsets of the 55,675 students from 22 countries who participated in the science literacy portion of TIMSS at the Population 3 level (IEA, 1997). The sample included in this study for the four research questions were comprised of between (1) 17,769 and 37,794 students from 15 countries, (2) 17,769 and 37,794 students from 15 countries, (3) 21,715 and 46,458 students from 18 countries, and (4) 19,518 and 46,458 students from 18 countries, respectively. A Pearson's product moment correlation was used to determine whether a relationship exists between the number of biology topics addressed by intended national science curricula and mean student achievement on selected items by country. No statistically significant correlation was found by country between biology achievement and number of topics. To determine whether a relationship exists between the topic duration of biology topics addressed by released, biology-oriented, Population 3 Science Literacy items and student achievement on those items, a Pearson's product moment correlation was also used. A statistically significant correlation between biology achievement and topic duration for only one topic (Interdependence of Life) was found at the .05 level of significance. A possible relationship between the degree of curricular focus of Population 3 TIMSS countries and student achievement on selected items by country was evaluated using a Pearson's product moment correlation. No statistically significant correlation by country between biology achievement and degree of curricular focus was found. A Pearson's product moment correlation was used to determine whether a relationship exists between science literacy

Arnold, Corey W; Oh, Andrea; Chen, Shawn; Speier, William

2016-02-01

Probabilistic topic models provide an unsupervised method for analyzing unstructured text. These models discover semantically coherent combinations of words (topics) that could be integrated in a clinical automatic summarization system for primary care physicians performing chart review. However, the human interpretability of topics discovered from clinical reports is unknown. Our objective is to assess the coherence of topics and their ability to represent the contents of clinical reports from a primary care physician's point of view. Three latent Dirichlet allocation models (50 topics, 100 topics, and 150 topics) were fit to a large collection of clinical reports. Topics were manually evaluated by primary care physicians and graduate students. Wilcoxon Signed-Rank Tests for Paired Samples were used to evaluate differences between different topic models, while differences in performance between students and primary care physicians (PCPs) were tested using Mann-Whitney U tests for each of the tasks. While the 150-topic model produced the best log likelihood, participants were most accurate at identifying words that did not belong in topics learned by the 100-topic model, suggesting that 100 topics provides better relative granularity of discovered semantic themes for the data set used in this study. Models were comparable in their ability to represent the contents of documents. Primary care physicians significantly outperformed students in both tasks. This work establishes a baseline of interpretability for topic models trained with clinical reports, and provides insights on the appropriateness of using topic models for informatics applications. Our results indicate that PCPs find discovered topics more coherent and representative of clinical reports relative to students, warranting further research into their use for automatic summarization.

2016-01-01

This topical review article gives an overview of the interplay between quantum information theory and thermodynamics of quantum systems. We focus on several trending topics including the foundations of statistical mechanics, resource theories, entanglement in thermodynamic settings, fluctuation theorems and thermal machines. This is not a comprehensive review of the diverse field of quantum thermodynamics; rather, it is a convenient entry point for the thermo-curious information theorist. Furthermore this review should facilitate the unification and understanding of different interdisciplinary approaches emerging in research groups around the world. (topical review)

Relationship between Usefulness Assessments and Perceptions of Work Task Complexity and Search Topic Specificity: An Exploratory Study

DEFF Research Database (Denmark)

Ingwersen, Peter; Wang, Peiling

2012-01-01

This research investigates the relations between the usefulness assessments of retrieved documents and the perceptions of task complexity and search topic specificity. Twenty-three academic researchers submitted 65 real task-based information search topics. These task topics were searched...... in an integrated document collection consisting of full text research articles in PDFs, abstracts, and bibliographic records (the iSearch Test Collection in Physics). The search results were provided to the researchers who, as task performers, made assessments of usefulness using a four-point sale (highly, fairly......, marginally, or not useful). In addition, they also assessed the perceived task complexity (highly, fairly, and routine/low) and the perceived specificity of the search topic (highly, fairly, and generic/low). It is found that highly specific topics associate with all degrees of task complexity, whereas...

Bibliographic analysis of scientific research on selected topics in public health nutrition in West Africa: Review of articles published from 1998 to 2008.

Science.gov (United States)

Aaron, Grant J; Wilson, Shelby E; Brown, Kenneth H

2010-01-01

Few countries in West Africa have the capacity for carrying out advanced training in nutrition and public health. To provide additional information on current regional applied nutrition research capacity and productivity, we analysed peer-reviewed articles on key public health nutrition topics that were published from 1998 to 2008. Using MEDLINE/PubMed, the following terms were searched: 'breast feeding', 'infant nutrition physiology' (comprising complementary feeding and weaning), 'protein energy malnutrition', 'nutrition and infection', 'vitamin A', 'iodine', 'zinc' and 'overweight', each linked with the term 'Western Africa'. In total, 412 unique articles (37±6 articles per year) were identified. Most research focused on infant and young child feeding practices, selected micronutrient deficiencies, and the emerging problem of overweight and obesity. The primary author of nearly half (46%) the publications was located in an institution outside of West Africa. Most articles were published in English (90%), and nearly half of all articles (41%) were cross-sectional studies. Our findings indicate that few peer-reviewed research studies are being published on key public health topics in the West African region, considering the magnitude of nutrition problems in this region. New approaches are needed to encourage and support research capacity and output in West Africa.

Full Text Available Designing usable forms of topical haemostatic agents is the most important activity during the design process, resulting in strengthened functional properties of the final medical devices. This study aimed to propose indications for a research programme based on risk management supporting the development of two usable forms of a topical haemostatic agent: chitosan/alginate lyophilized foam and chitosan/alginate impregnated gauze. Both of the usable forms of the topical haemostatic agent, being the main part of the modified combat gauze, were fabricated using the chitosan/alginate complex. Risk analysis is helpful in developing an appropriate research programme, significantly reducing the risk to an acceptable level.

Syntacticized topics in Kurmuk

DEFF Research Database (Denmark)

Andersen, Torben

2015-01-01

This article argues that Kurmuk, a little-described Western Nilotic language, is characterized by a syntacticized topic whose grammatical relation is variable. In this language, declarative clauses have as topic an obligatory preverbal NP which is either a subject, an object or an adjunct....... The grammatical relation of the topic is expressed by a voice-like inflection of the verb, here called orientation. While subject-orientation is morphologically unmarked, object-oriented and adjunct-oriented verbs are marked by a subject suffix or by a suffix indicating that the topic is not subject, and adjunct......-orientation differs from object-orientation by a marked tone pattern. Topic choice largely reflects information structure by indicating topic continuity. The topic also plays a crucial role in relative clauses and in clauses with contrastive constituent focus, in that objects and adjuncts can only be relativized...

Topical amitriptyline and ketamine for the treatment of neuropathic pain.

Science.gov (United States)

Mercadante, Sebastiano

2015-01-01

A neuropathy is a disturbance of function or pathological change in nerves. In some cases, peripheral neuropathic pain may occur due to a lesion or disease of the peripheral somatosensory nervous system. Efficacy of different agents for peripheral neuropathic pain conditions is less than optimal. The administration of topical analgesics might be an option, due to the potential of reduced adverse effects and increased patient compliance. There is major interest in compounding topical analgesics for peripheral neuropathic pain, but several challenges remain for this approach. Topical analgesics have the potential to be a valuable additional approach for the management of peripheral neuropathic pain. Topical amitriptyline-ketamine combination (AK) is a promising agent for peripheral neuropathic pain conditions. Some studies have shown its efficacy in neuropathic pain conditions. However, this data was not uniformely obtained and its role remains still controversial. Efficacy may depend on many factors, including the choice of the vehicle, the concentration, the pain site, and specific diseases. More studies are necessary to support the use of AK in clinical practice.

Ultraviolet radiation (UVR) contributes to the vast majority of nonmelanoma skin cancer (NMSC). As the incidence of NMSC continues to rise, topical therapies will be used with increasing frequency. Topical therapies may benefit high-risk surgical candidates as an alternative treatment modality and may improve overall cosmesis. The most commonly employed topical therapies are imiquimod, 5-fluorouracil (5-FU), and diclofenac. To review the detailed mechanism of action and side-effect profiles of each topical therapy used to treat NMSC and to explore newly discovered actions. Uncommon adverse events are also presented. An extensive literature search was performed to describe the pharmacologic actions of imiquimod, 5-FU, and diclofenac. A keen understanding of the pharmacologic concepts of these topical therapies may aid the dermatologic surgeon in making sound choices before, during, and after surgery. © 2011 by the American Society for Dermatologic Surgery, Inc.

Reflections on the Journal of Applied Psychology for 1989 to 1994: Changes in major research themes and practices over 25 years.

Science.gov (United States)

Schmitt, Neal

2017-03-01

Informal observations concerning journal content indicates that research investigating organizational behavior topics, including work on the structure of groups and determinants and consequences of group process along with the role of leadership in groups, has increased. Some topics have disappeared (e.g., job analysis, human factors, union-related work, consumer behavior) and others are declining (e.g., research methods, psychometrics). Perhaps the biggest change is in the length of articles, which is mostly a function of the inclusion of greater numbers of references and appendix material. Publishing some of this material in supplementary online materials is now current practice in the Journal of Applied Psychology. Concerns about use of journal space may also be entirely moot, if electronic publishing as opposed to print publishing becomes the norm. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

Detection of Cases of Noncompliance to Drug Treatment in Patient Forum Posts: Topic Model Approach.

Science.gov (United States)

Abdellaoui, Redhouane; Foulquié, Pierre; Texier, Nathalie; Faviez, Carole; Burgun, Anita; Schück, Stéphane

2018-03-14

Medication nonadherence is a major impediment to the management of many health conditions. A better understanding of the factors underlying noncompliance to treatment may help health professionals to address it. Patients use peer-to-peer virtual communities and social media to share their experiences regarding their treatments and diseases. Using topic models makes it possible to model themes present in a collection of posts, thus to identify cases of noncompliance. The aim of this study was to detect messages describing patients' noncompliant behaviors associated with a drug of interest. Thus, the objective was the clustering of posts featuring a homogeneous vocabulary related to nonadherent attitudes. We focused on escitalopram and aripiprazole used to treat depression and psychotic conditions, respectively. We implemented a probabilistic topic model to identify the topics that occurred in a corpus of messages mentioning these drugs, posted from 2004 to 2013 on three of the most popular French forums. Data were collected using a Web crawler designed by Kappa Santé as part of the Detec't project to analyze social media for drug safety. Several topics were related to noncompliance to treatment. Starting from a corpus of 3650 posts related to an antidepressant drug (escitalopram) and 2164 posts related to an antipsychotic drug (aripiprazole), the use of latent Dirichlet allocation allowed us to model several themes, including interruptions of treatment and changes in dosage. The topic model approach detected cases of noncompliance behaviors with a recall of 98.5% (272/276) and a precision of 32.6% (272/844). Topic models enabled us to explore patients' discussions on community websites and to identify posts related with noncompliant behaviors. After a manual review of the messages in the noncompliance topics, we found that noncompliance to treatment was present in 6.17% (276/4469) of the posts. ©Redhouane Abdellaoui, Pierre Foulquié, Nathalie Texier, Carole

Bottlenecks in the development of topical analgesics: molecule, formulation, dose-finding, and phase III design

Full Text Available Jan M Keppel Hesselink,1 David J Kopsky,2 Stephen M Stahl3 1Institute Neuropathic Pain, Bosch en Duin, the Netherlands; 2Institute Neuropathic Pain, Amsterdam, the Netherlands; 3University of California San Diego, La Jolla, CA, USA Abstract: Topical analgesics can be defined as topical formulations containing analgesics or co-analgesics. Since 2000, interest in such formulations has been on the rise. There are, however, four critical issues in the research and development phases of topical analgesics: 1 The selection of the active pharmaceutical ingredient. Analgesics and co-analgesics differ greatly in their mechanism of action, and it is required to find the most optimal fit between such mechanisms of action and the pathogenesis of the targeted (neuropathic pain. 2 Issues concerning the optimized formulation. For relevant clinical efficacy, specific characteristics for the selected vehicle (eg, cream base or gel base are required, depending on the physicochemical characteristics of the active pharmaceutical ingredient(s to be delivered. 3 Well-designed phase II dose-finding studies are required, and, unfortunately, such trials are missing. In fact, we will demonstrate that underdosing is one of the major hurdles to detect meaningful and statistically relevant clinical effects of topical analgesics. 4 Selection of clinical end points and innovatively designed phase III trials. End point selection can make or break a trial. For instance, to include numbness together with tingling as a composite end point for neuropathic pain seems stretching the therapeutic impact of an analgesic too far. Given the fast onset of action of topical analgesics (usually within 30 minutes, enrichment designs might enhance the chances for success, as the placebo response might decrease. Topical analgesics may become promising inroads for the treatment of neuropathic pain, once sufficient attention is given to these four key aspects. Keywords: topical, analgesics

2005-05-01

Full Text Available On today's "wired" college campuses, students avail themselves in increasing numbers of electronic channels, most notably e-mail, as a means to consult with their professors. While some research has investigated the purposes for which university students communicate with their instructors via e-mail, little research has examined differences in e-mail use between American and international students. In the present study, e-mail messages sent by American and international students enrolled in a teacher-preparation program to their professor were collected over the course of one semester. The messages were examined for three major communication topics (facilitative, substantive, relational and communication strategies (requesting, negotiating, reporting. Results indicate quantitative and qualitative differences in American and international students' e-mail topics and strategies, suggesting, similar to findings for face-to-face academic advising sessions, that American students demonstrate greater initiative and ability to adapt to the spatial and temporal remoteness between interlocutors in e-mail interaction, especially when using e-mail to solicit face-to-face appointments and input on projects. Findings also show that messages from both groups of students contained substantial relational communication, perhaps in an attempt to compensate for the lack of visual and paralinguistic clues in the e-mail medium.

[Bioequivalence of dermatological topical medicines:the Brazilian scenario and the challenges for health surveillance].

Soares, Kelen Carine Costa; Moraes, Marcelo Vogler; Gelfuso, Guilherme Martins; Gratieri, Taís

2015-11-01

The comparative evaluation required for the registration of generic topical medicines in Brazil is conducted by means of a pharmaceutical equivalence study, which merely assesses the physical/chemical and microbiological parameters of the formulations. At the international level, clinical or pharmacodynamic studies are now being required to prove the efficacy and safety of semisolid topical generic formulations. This work presents a comparison of the different requirements for the registration of topical formulations, taking into consideration the various regulatory authorities, and presents a survey of topical medicines registered in Brazil prior to 2013. The survey revealed that in comparison with the USA there were many more copies of these formulations registered in Brazil. This fact, together with the large number of studies in the literature showing the lack of bioequivalence of topical medication, is clear proof of the major importance of the need to realign Brazilian legislation with respect to the technical requirements for the registration of generic and similar medication for dermatological topical application in Brazil.

History of the APS Topical Group on Shock Compression of Condensed Matter

International Nuclear Information System (INIS)

Forbes, J W

2001-01-01

In order to provide broader scientific recognition and to advance the science of shock compressed condensed matter, a group of American Physical Society (APS) members worked within the Society to make this field an active part of the APS. Individual papers were presented at APS meetings starting in the 1940's and shock wave sessions were organized starting with the 1967 Pasadena meeting. Shock wave topical conferences began in 1979 in Pullman, WA. Signatures were obtained on a petition in 1984 from a balanced cross-section of the shock wave community to form an APS Topical Group (TG). The APS Council officially accepted the formation of the Shock Compression of Condensed Matter (SCCM) TG at its October 1984 meeting. This action firmly aligned the shock wave field with a major physical science organization. Most early topical conferences were sanctioned by the APS while those held after 1992 were official APS meetings. The topical group organizes a shock wave topical conference in odd numbered years while participating in shock wavehigh pressure sessions at APS general meetings in even numbered years

Science teacher orientations and PCK across science topics in grade 9 earth science

Science.gov (United States)

Campbell, Todd; Melville, Wayne; Goodwin, Dawne

2017-07-01

While the literature is replete with studies examining teacher knowledge and pedagogical content knowledge (PCK), few studies have investigated how science teacher orientations (STOs) shape classroom instruction. Therefore, this research explores the interplay between a STOs and the topic specificity of PCK across two science topics within a grade 9 earth science course. Through interviews and observations of one teacher's classroom across two sequentially taught, this research contests the notion that teachers hold a single way of conceptualising science teaching and learning. In this, we consider if multiple ontologies can provide potential explanatory power for characterising instructional enactments. In earlier work with the teacher in this study, using generic interview prompts and general discussions about science teaching and learning, we accepted the existence of a unitary STO and its promise of consistent reformed instruction in the classroom. However, upon close examination of instruction focused on different science topics, evidence was found to demonstrate the explanatory power of multiple ontologies for shaping characteristically different epistemological constructions across science topics. This research points to the need for care in generalising about teacher practice, as it reveals that a teacher's practice, and orientation, can vary, dependent on the context and science topics taught.

Topical drug administration offers an attractive route with minimal invasiveness. It also avoids limitations of intravenous administration such as the first pass metabolism and presystemic elimination within the gastrointestinal tract. Furthermore, topical drug administration is safe, have few side effects, is easy to apply, and offers a fast onset of action. However, the development of effective topical formulations still represents a challenge for the desired effect to be reached, locally or systemically. Solid lipid nanoparticles and nanostructured lipid carriers are particular candidates to overcome the problem of topical drug administration. The nanometric particle size of lipid nanoparticles favors the physical adhesion to the skin or mucosal, what can also be attained with the formation of hybrid (nanoparticles/polymer) systems. In this review, we discuss the major challenges for lipid nanoparticles formulations for topical application to oral mucosa, skin, and eye, highlighting the strategies to improve the performance of lipid nanoparticles for topical applications. Next, we critically analyzed the in vitro and in vivo approaches used to evaluate lipid nanoparticles performance and toxicity. We addressed some major drawbacks related to lipid nanoparticle topical formulations and concluded the key points that have to be overcome to help them to reach the market in topical formulations to oral mucosa, skin and eye.

Climate is traditionally one of the main fields of research interest and objects for study in Bulgaria. Therefore, many investigations on its genesis and specific features are carried out in the past and present. Recently, climate change research appears to be the most actual topic and it is in the centre of climatic studies. A major part of these studies are realized at the National Institute of Meteorology and Hydrology (NIMH) because of its essential role in collection and analysis of the basic climatic data for the country. A brief description of the climate change research at NIMH is presented and the obtained results are summarized

New guidelines for topical NSAIDs in the osteoarthritis treatment paradigm.

Science.gov (United States)

Altman, Roy D

2010-12-01

Osteoarthritis (OA), the most common form of arthritis, often affects hands, hips, and knees and involves an estimated 26.9 million US adults. Women have a higher prevalence of OA, and the risk of developing OA increases with age, obesity, and joint malalignment. OA typically presents with pain and reduced function. Therapeutic programs are often multimodal and must take into account pharmaceutical toxicities and patient comorbidities. For example, nonsteroidal anti-inflammatory drugs (NSAIDs) are associated with cardiovascular, gastrointestinal, and renal adverse events. Topical NSAIDs offer efficacy with reduced systemic drug exposure. This is a review of current guideline recommendations regarding the use of topical NSAIDs in OA of the hand and knee. Articles were identified by PubMed search (January 1, 2000 to May 21, 2010). Several current guidelines for management of OA recommend topical NSAIDs, indicating them as a safe and effective treatment. One guideline recommends that topical NSAIDs be considered as first-line pharmacologic therapy. A US guideline for knee OA recommends topical NSAIDs in older patients and in patients with increased gastrointestinal risk. The consensus across US and European OA guidelines is that topical NSAIDs are a safe and effective treatment for OA. Because the research base on topical NSAIDs for OA is small, guidelines will continue to evolve.

A Data-Based Approach to Discovering Multi-Topic Influential Leaders.

Directory of Open Access Journals (Sweden)

Xing Tang

Full Text Available Recently, increasing numbers of users have adopted microblogging services as their main information source. However, most of them find themselves drowning in the millions of posts produced by other users every day. To cope with this, identifying a set of the most influential people is paramount. Moreover, finding a set of related influential users to expand the coverage of one particular topic is required in real world scenarios. Most of the existing algorithms in this area focus on topology-related methods such as PageRank. These methods mine link structures to find the expected influential rank of users. However, because they ignore the interaction data, these methods turn out to be less effective in social networks. In reality, a variety of topics exist within the information diffusing through the network. Because they have different interests, users play different roles in the diffusion of information related to different topics. As a result, distinguishing influential leaders according to different topics is also worthy of research. In this paper, we propose a multi-topic influence diffusion model (MTID based on traces acquired from historic information. We decompose the influential scores of users into two parts: the direct influence determined by information propagation along the link structure and indirect influence that extends beyond the restrictions of direct follower relationships. To model the network from a multi-topical viewpoint, we introduce topic pools, each of which represents a particular topic information source. Then, we extract the topic distributions from the traces of tweets, determining the influence propagation probability and content generation probability. In the network, we adopt multiple ground nodes representing topic pools to connect every user through bidirectional links. Based on this multi-topical view of the network, we further introduce the topic-dependent rank (TD-Rank algorithm to identify the multi-topic

Atopic keratoconjunctivitis (AKC) is a chronic ocular surface non-infectious inflammatory condition that atopic dermatitis patients may suffer at any time point in the course of their dermatologic disease and is independent of its degree of severity. AKC is usually not self resolving and it poses a higher risk of corneal injuries and severe sequelae. Management of AKC should prevent or treat corneal damage. Although topical corticosteroids remain the standard treatment for patients with AKC, prolonged use may lead to complications. Topical cyclosporine A (CsA) may improve AKC signs and symptoms, and be used as a corticosteroid sparing agent. To determine the efficacy and gather evidence on safety from randomised controlled trials (RCTs) of topical CsA in patients with AKC. We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (The Cochrane Library 2012, Issue 6), MEDLINE (January 1946 to July 2012), EMBASE (January 1980 to July 2012), Latin American and Caribbean Literature on Health Sciences (LILACS) (January 1982 to July 2012), Cumulative Index to Nursing and Allied Health Literature (CINAHL) (January 1937 to July 2012), OpenGrey (System for Information on Grey Literature in Europe) (www.opengrey.eu/), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), ClinicalTrials.gov (www.clinicaltrials.gov), the WHO International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en), the IFPMA Clinical Trials Portal (http://clinicaltrials.ifpma.org/no_cache/en/myportal/index.htm) and Web of Science Conference Proceedings Citation Index- Science (CPCI-S). We did not use any date or language restrictions in the electronic searches for trials. The electronic databases were last searched on 9 July 2012.

Current and Emerging Topical Antibacterials and Antiseptics: Agents, Action, and Resistance Patterns.

Science.gov (United States)

Williamson, Deborah A; Carter, Glen P; Howden, Benjamin P

2017-07-01

Bacterial skin infections represent some of the most common infectious diseases globally. Prevention and treatment of skin infections can involve application of a topical antimicrobial, which may be an antibiotic (such as mupirocin or fusidic acid) or an antiseptic (such as chlorhexidine or alcohol). However, there is limited evidence to support the widespread prophylactic or therapeutic use of topical agents. Challenges involved in the use of topical antimicrobials include increasing rates of bacterial resistance, local hypersensitivity reactions (particularly to older agents, such as bacitracin), and concerns about the indiscriminate use of antiseptics potentially coselecting for antibiotic resistance. We review the evidence for the major clinical uses of topical antibiotics and antiseptics. In addition, we review the mechanisms of action of common topical agents and define the clinical and molecular epidemiology of antimicrobial resistance in these agents. Moreover, we review the potential use of newer and emerging agents, such as retapamulin and ebselen, and discuss the role of antiseptic agents in preventing bacterial skin infections. A comprehensive understanding of the clinical efficacy and drivers of resistance to topical agents will inform the optimal use of these agents to preserve their activity in the future.

Electronic cigarette (e-cigarette) is an emerging product with a rapid-growth market in recent years. Social media has become an important platform for information seeking and sharing. We aim to mine hidden topics from e-cigarette datasets collected from different social media platforms. This paper aims to gain a systematic understanding of the characteristics of various types of social media, which will provide deep insights into how consumers and policy makers effectively use social media to track e-cigarette-related content and adjust their decisions and policies. We collected data from Reddit (27,638 e-cigarette flavor-related posts from January 1, 2011, to June 30, 2015), JuiceDB (14,433 e-juice reviews from June 26, 2013 to November 12, 2015), and Twitter (13,356 "e-cig ban"-related tweets from January, 1, 2010 to June 30, 2015). Latent Dirichlet Allocation, a generative model for topic modeling, was used to analyze the topics from these data. We found four types of topics across the platforms: (1) promotions, (2) flavor discussions, (3) experience sharing, and (4) regulation debates. Promotions included sales from vendors to users, as well as trades among users. A total of 10.72% (2,962/27,638) of the posts from Reddit were related to trading. Promotion links were found between social media platforms. Most of the links (87.30%) in JuiceDB were related to Reddit posts. JuiceDB and Reddit identified consistent flavor categories. E-cigarette vaping methods and features such as steeping, throat hit, and vapor production were broadly discussed both on Reddit and on JuiceDB. Reddit provided space for policy discussions and majority of the posts (60.7%) holding a negative attitude toward regulations, whereas Twitter was used to launch campaigns using certain hashtags. Our findings are based on data across different platforms. The topic distribution between Reddit and JuiceDB was significantly different (Puser discussions focused on different perspectives across the

To present a model of translational research for behavioral science that communicates the role of behavioral research at each phase of translation. A task force identified gaps in knowledge regarding behavioral translational research processes and made recommendations regarding advancement of knowledge. A comprehensive model of translational behavioral research was developed. This model represents T1, T2, and T3 research activities, as well as Phase 1, 2, 3, and 4 clinical trials. Clinical illustrations of translational processes are also offered as support for the model. Behavioral science has struggled with defining a translational research model that effectively articulates each stage of translation and complements biomedical research. Our model defines key activities at each phase of translation from basic discovery to dissemination/implementation. This should be a starting point for communicating the role of behavioral science in translational research and a catalyst for better integration of biomedical and behavioral research. © The Author 2015.

Human-competitive automatic topic indexing

CERN Document Server

Medelyan, Olena

2009-01-01

Topic indexing is the task of identifying the main topics covered by a document. These are useful for many purposes: as subject headings in libraries, as keywords in academic publications and as tags on the web. Knowing a document’s topics helps people judge its relevance quickly. However, assigning topics manually is labor intensive. This thesis shows how to generate them automatically in a way that competes with human performance. Three kinds of indexing are investigated: term assignment, a task commonly performed by librarians, who select topics from a controlled vocabulary; tagging, a popular activity of web users, who choose topics freely; and a new method of keyphrase extraction, where topics are equated to Wikipedia article names. A general two-stage algorithm is introduced that first selects candidate topics and then ranks them by significance based on their properties. These properties draw on statistical, semantic, domain-specific and encyclopedic knowledge. They are combined using a machine learn...

Topic shift impairs pronoun resolution during sentence comprehension: Evidence from event-related potentials.

Science.gov (United States)

Xu, Xiaodong; Zhou, Xiaolin

2016-02-01

This study investigated how topic shift and topic continuation influence pronoun interpretation in Chinese. ERPs recorded on pronouns in topic structure showed stronger and earlier late positive responses (P600) for the topic-shift than for the topic-continuation conditions. However, in nontopic structure where the subject (denoting only subjecthood), rather than the topic (denoting both topichood and subjecthood), acted as the antecedent of the pronoun, almost indistinguishable P600 responses were obtained on the pronoun regardless of whether it was referring to the subject (i.e., subject continuation) or the object (i.e., subject shift). Moreover, stronger and earlier P600 responses were elicited by pronouns in the topic-shift than in the subject-shift conditions, although there was no difference between the topic-continuation and the subject-continuation conditions. These findings suggest that topic shift results in greater difficulty in the resolution stage of referential processing, although the bonding process is not sensitive to the manipulation of topic status, and that topic has a privileged cognitive status relative to other nontopic entities (e.g., subject) in real-time language processing. © 2015 Society for Psychophysiological Research.

Muralidhara, Sachin; Paul, Michael J

2018-06-29

Social media provides a complementary source of information for public health surveillance. The dominate data source for this type of monitoring is the microblogging platform Twitter, which is convenient due to the free availability of public data. Less is known about the utility of other social media platforms, despite their popularity. This work aims to characterize the health topics that are prominently discussed in the image-sharing platform Instagram, as a step toward understanding how this data might be used for public health research. The study uses a topic modeling approach to discover topics in a dataset of 96,426 Instagram posts containing hashtags related to health. We use a polylingual topic model, initially developed for datasets in different natural languages, to model different modalities of data: hashtags, caption words, and image tags automatically extracted using a computer vision tool. We identified 47 health-related topics in the data (kappa=.77), covering ten broad categories: acute illness, alternative medicine, chronic illness and pain, diet, exercise, health care & medicine, mental health, musculoskeletal health and dermatology, sleep, and substance use. The most prevalent topics were related to diet (8,293/96,426; 8.6% of posts) and exercise (7,328/96,426; 7.6% of posts). A large and diverse set of health topics are discussed in Instagram. The extracted image tags were generally too coarse and noisy to be used for identifying posts but were in some cases accurate for identifying images relevant to studying diet and substance use. Instagram shows potential as a source of public health information, though limitations in data collection and metadata availability may limit its use in comparison to platforms like Twitter. ©Sachin Muralidhara, Michael J.

Psoriatic patients have different attitudes toward their condition. Topical medications are essential for the treatment of psoriasis, but the majority of patients do not adhere to these therapies. Objective: The history of treatment success or failure seems to influence patient attitude toward topical therapy. Therefore, it is important to understand the psychological, experiential, and motivational aspects that could be critical for treatment adherence, and to describe the different attitudes toward topical treatment. Furthermore, the physician–patient relationship and the willingness to trust the dermatologist may have a substantial role in encouraging or discouraging patients’ attitudes toward topical therapy. Methods: A survey was designed to collect aspects that could be relevant to understanding different patient attitudes toward psoriasis and its treatments. A total of 495 self-administered questionnaires compiled by psoriatic patients were analyzed from 20 Italian specialized hospital centers in order to provide a nationwide picture. Results: Psoriatic patients have different perceptions and experiences in relation to their condition: half of them consider psoriasis as a disease, while the other half consider psoriasis as a disorder or a nuisance. Topical therapy is the most widely used treatment, even though it is not considered the most effective one and often perceived to be cosmetic. The main findings are: 1

Key Concept Identification: A Comprehensive Analysis of Frequency and Topical Graph-Based Approaches

Directory of Open Access Journals (Sweden)

Muhammad Aman

2018-05-01

Full Text Available Automatic key concept extraction from text is the main challenging task in information extraction, information retrieval and digital libraries, ontology learning, and text analysis. The statistical frequency and topical graph-based ranking are the two kinds of potentially powerful and leading unsupervised approaches in this area, devised to address the problem. To utilize the potential of these approaches and improve key concept identification, a comprehensive performance analysis of these approaches on datasets from different domains is needed. The objective of the study presented in this paper is to perform a comprehensive empirical analysis of selected frequency and topical graph-based algorithms for key concept extraction on three different datasets, to identify the major sources of error in these approaches. For experimental analysis, we have selected TF-IDF, KP-Miner and TopicRank. Three major sources of error, i.e., frequency errors, syntactical errors and semantical errors, and the factors that contribute to these errors are identified. Analysis of the results reveals that performance of the selected approaches is significantly degraded by these errors. These findings can help us develop an intelligent solution for key concept extraction in the future.

Mapping epidemiology's past to inform its future: metaknowledge analysis of epidemiologic topics in leading journals, 1974-2013.

Science.gov (United States)

Trinquart, Ludovic; Galea, Sandro

2015-07-15

An empiric perspective on what epidemiology has studied over time might inform discussions about future directions for the discipline. We aimed to identify the main areas of epidemiologic inquiry and determine how they evolved over time in 5 high-impact epidemiologic journals. We analyzed the titles and abstracts of 20,895 articles that were published between 1974 and 2013. In 5 time periods that reflected approximately equal numbers of articles, we identified the main topics by clustering terms based on co-occurrence. Infectious disease and cardiovascular disease epidemiology were the prevailing topics over the 5 periods. Cancer epidemiology was a major topic from 1974 to 2001 but disappeared thereafter. Nutritional epidemiology gained relative importance from 1974 to 2013. Environmental epidemiology appeared during 1996-2001 and continued to be important, whereas 2 clusters related to methodology and meta-analysis in genetics appeared during 2008-2013. Several areas of epidemiology, including injury or psychiatric epidemiology, did not make an appearance as major topics at any time. In an ancillary analysis of 6 high-impact general medicine journals, we found patterns of epidemiologic articles that were overall consistent with the findings in epidemiologic journals. This metaknowledge investigation allowed identification of the dominant topics in and conversely those that were absent from 5 major epidemiologic journals. We discuss implications for the field. © The Author 2015. Published by Oxford University Press on behalf of the Johns Hopkins Bloomberg School of Public Health. All rights reserved.

Topical vs. systemic treatments for acute otitis media.

Science.gov (United States)

Thornton, Kathy; Parrish, Francie; Swords, Christine

2011-01-01

Acute otitis media (AOM) is a common condition in children that is often treated with systemic antibiotic therapy; however, research suggests that non-complicated AOM will resolve spontaneously using only eardrops. To determine best practice for the use of systematic antibiotics compared to topical treatment of AOM, a systematic review of evidence was conducted. Cochrane, Medline, CINAHL, and other databases were searched. Inclusion criteria were studies published from 1995-2010 that included children with AOM and were randomized controlled trials (RCTs). Five systematic reviews and five RCTs were included in the review. Current evidence recommends using topical and other alternative approaches for treating non-complicated AOM in children 2 years of age or older; however, many practitioners are not currently following these recommendations for various reasons. Additional research to address these reasons may help determine how to improve practitioner adherence to best practice evidence and guidelines to help reduce the unnecessary use of systemic antibiotics.

2007-01-01

This systematic review aimed to evaluate the best available evidence regarding the effectiveness of topical skin care interventions for residents of aged care facilities. Natural changes to skin, as well as increased predisposition to pressure sores and incontinence, means residents of aged care facilities readily require topical skin care. A range of interventions exist that aim to maintain or improve the integrity of skin of older adults. Pubmed, Embase, Current Contents, CINAHL and The Cochrane Library databases were searched, as well as Health Technology Assessment websites up to April 2003. Systematic reviews and randomized or non-randomized controlled trials were evaluated for quality and data were independently extracted by two reviewers. The effectiveness of topical skin interventions was variable and dependent on the skin condition being treated. Studies examined the effectiveness of washing products on incontinence irritated skin. Disposable bodyworns may prevent deterioration of skin condition better than non-disposable underpads or bodyworns. Clinisan, a no-rinse cleanser may reduce the incidence of incontinence associated pressure ulcers when compared with soap and water. In general the quality of evidence for interventions to improve or maintain the skin condition in the older person was poor and more research in this area is needed. Skin care is a major issue for nurses working with older people. On the basis of this review no clear recommendations can be made. This lack of strong evidence for nurses to base effective practice decisions is problematic. However, the 'best' evidence suggests that disposable bodyworns are a good investment in the fight against skin deterioration. No rinse cleansers are to be preferred over soap and the use of the bag bath appears to be a useful practice to reduce the risk of dry skin (a risk factor for breaches in skin integrity).

2017-08-21

We are witnessing an explosive increase in redundant and overlapping publications of systematic reviews and meta-analyses (SRs/MAs) on the same topic, which often present conflicting results and interpretations, in the current medical literature. They represent wasted efforts on the part of investigators and peer reviewers and may confuse and possibly mislead clinicians and policymakers. Here, we present a protocol for a meta-epidemiological investigation to describe how often there are overlapping SRs/MAs on the same topic, to assess the quality of these multiple publications, and to investigate the causes of discrepant results between multiple SRs/MAs in the field of major surgery. We will use MEDLINE/PubMed to identify all SRs/MAs of randomised controlled trials (RCTs) published in 2015 regarding major surgical interventions. After identifying the 'benchmark' SRs/MAs published in 2015, a process of screening in MEDLINE will be carried out to identify the previous SRs/MAs of RCTs on the same topic that were published within 5 years of the 'benchmark' SRs/MAs. We will tabulate the number of previous SRs/MAs on the same topic of RCTs, and then describe their variations in numbers of RCTs included, sample sizes, effect size estimates and other characteristics. We will also assess the differences in quality of each SR/MA using A Measurement Tool to Assess Systematic Reviews (AMSTAR) score. Finally, we will investigate the potential reasons to explain the discrepant results between multiple SRs/MAs. No formal ethical approval and informed consent are required because this study will not collect primary individual data. The intended audiences of the findings include clinicians, healthcare researchers and policymakers. We will publish our findings as a scientific report in a peer-reviewed journal.

Selected Topics in Nuclear Theory. Lectures Given at the International Summer School on Selected Topics in Nuclear Theory

Energy Technology Data Exchange (ETDEWEB)

Janouch, F. [ed.

1963-01-15

An International Summer School on Selected Topics in Nuclear Theory was held during the period 20 August to 9 September 1962 in the Low Tatra Mountains, Czechoslovakia, under the auspices of the Nuclear Research Institute of the Czechoslovak Academy of Sciences, with financial support from the International Atomic Energy Agency. In view of the wide interest of the seven topics considered there and of the speed with which the field of theoretical physics is developing, the Agency decided to make available its facilities for rapid publication and to publish the lectures under its own imprint; however, all editorial and composition work has been performed under the supervision of the general editor. Dr. F. Janouch of the Nuclear Research Institute of the Czechoslovak Academy of Sciences. The problem of keeping in touch with the rapidly changing but fundamental field of theoretical physics is a difficult one, particularly for scientists in the developing countries. It is hoped that such publications as the present one and the companion volume containing the lectures presented at the Agency's Seminar on Theoretical Physics at Trieste w ill help, at least in a modest fashion, to overcome these difficulties.

Incorporating Topic Assignment Constraint and Topic Correlation Limitation into Clinical Goal Discovering for Clinical Pathway Mining

Directory of Open Access Journals (Sweden)

Xiao Xu

2017-01-01

Full Text Available Clinical pathways are widely used around the world for providing quality medical treatment and controlling healthcare cost. However, the expert-designed clinical pathways can hardly deal with the variances among hospitals and patients. It calls for more dynamic and adaptive process, which is derived from various clinical data. Topic-based clinical pathway mining is an effective approach to discover a concise process model. Through this approach, the latent topics found by latent Dirichlet allocation (LDA represent the clinical goals. And process mining methods are used to extract the temporal relations between these topics. However, the topic quality is usually not desirable due to the low performance of the LDA in clinical data. In this paper, we incorporate topic assignment constraint and topic correlation limitation into the LDA to enhance the ability of discovering high-quality topics. Two real-world datasets are used to evaluate the proposed method. The results show that the topics discovered by our method are with higher coherence, informativeness, and coverage than the original LDA. These quality topics are suitable to represent the clinical goals. Also, we illustrate that our method is effective in generating a comprehensive topic-based clinical pathway model.

Science.gov (United States)

Williams, A C

2013-01-01

Brian Barry published over 300 research articles across topics ranging from colloid science, vasoconstriction and the importance of thermodynamics in dermal drug delivery to exploring the structure and organisation of the stratum corneum barrier lipids and numerous strategies for improving topical and transdermal drug delivery, including penetration enhancers, supersaturation, coacervation, eutectic formation and the use of varied liposomes. As research in the area blossomed in the early 1980s, Brian wrote the book that became essential reading for both new and established dermal delivery scientists, explaining the background mathematics and principles through to formulation design. Brian also worked with numerous scientists, as collaborators and students, who have themselves taken his rigorous approach to scientific investigation into their own research groups. This paper can only describe a small fraction of the many significant contributions that Brian made to the field during his 40-year academic career.

Strategies of persuasion in offers to participate in cancer clinical trials I: Topic placement and topic framing.

Science.gov (United States)

Barton, Ellen; Eggly, Susan; Winckles, Andrew; Albrecht, Terrance L

2014-01-01

Clinical trials are the gold standard in medical research evaluating new treatments in cancer care; however, in the United States, too few patients enroll in trials, especially patients from minority groups. Offering patients the option of a clinical trial is an ethically-charged communicative event for oncologists. One particularly vexed ethical issue is the use of persuasion in trial offers. Based on a corpus of 22 oncology encounters with Caucasian-American (n = 11) and African-American (n = 11) patients, this discourse analysis describes oncologists' use of two persuasive strategies related to the linguistic structure of trial offers: topic placement and topic framing. Findings are presented in total and by patient race, and discussed in terms of whether these strategies may constitute ethical or unethical persuasion, particularly with respect to the ethical issue of undue influence and the social issue of underrepresentation of minorities in cancer clinical trials.

Curricular priorities for business ethics in medical practice and research: recommendations from Delphi consensus panels.

Science.gov (United States)

DuBois, James M; Kraus, Elena M; Gursahani, Kamal; Mikulec, Anthony; Bakanas, Erin

2014-11-15

No published curricula in the area of medical business ethics exist. This is surprising given that physicians wrestle daily with business decisions and that professional associations, the Institute of Medicine, Health and Human Services, Congress, and industry have issued related guidelines over the past 5 years. To fill this gap, the authors aimed (1) to identify the full range of medical business ethics topics that experts consider important to teach, and (2) to establish curricular priorities through expert consensus. In spring 2012, the authors conducted an online Delphi survey with two heterogeneous panels of experts recruited in the United States. One panel focused on business ethics in medical practice (n = 14), and 1 focused on business ethics in medical research (n = 12). Panel 1 generated an initial list of 14 major topics related to business ethics in medical practice, and subsequently rated 6 topics as very important or essential to teach. Panel 2 generated an initial list of 10 major topics related to business ethics in medical research, and subsequently rated 5 as very important or essential. In both domains, the panel strongly recommended addressing problems that conflicts of interest can cause, legal guidelines, and the goals or ideals of the profession. The Bander Center for Medical Business Ethics at Saint Louis University will use the results of the Delphi panel to develop online curricular resources for each of the highest rated topics.

Learning From Short Text Streams With Topic Drifts.

Science.gov (United States)

Li, Peipei; He, Lu; Wang, Haiyan; Hu, Xuegang; Zhang, Yuhong; Li, Lei; Wu, Xindong

2017-09-18

Short text streams such as search snippets and micro blogs have been popular on the Web with the emergence of social media. Unlike traditional normal text streams, these data present the characteristics of short length, weak signal, high volume, high velocity, topic drift, etc. Short text stream classification is hence a very challenging and significant task. However, this challenge has received little attention from the research community. Therefore, a new feature extension approach is proposed for short text stream classification with the help of a large-scale semantic network obtained from a Web corpus. It is built on an incremental ensemble classification model for efficiency. First, more semantic contexts based on the senses of terms in short texts are introduced to make up of the data sparsity using the open semantic network, in which all terms are disambiguated by their semantics to reduce the noise impact. Second, a concept cluster-based topic drifting detection method is proposed to effectively track hidden topic drifts. Finally, extensive studies demonstrate that as compared to several well-known concept drifting detection methods in data stream, our approach can detect topic drifts effectively, and it enables handling short text streams effectively while maintaining the efficiency as compared to several state-of-the-art short text classification approaches.

Using NASA Space Imaging Technology to Teach Earth and Sun Topics

Science.gov (United States)

Verner, E.; Bruhweiler, F. C.; Long, T.

2011-12-01

We teach an experimental college-level course, directed toward elementary education majors, emphasizing "hands-on" activities that can be easily applied to the elementary classroom. This course, Physics 240: "The Sun-Earth Connection" includes various ways to study selected topics in physics, earth science, and basic astronomy. Our lesson plans and EPO materials make extensive use of NASA imagery and cover topics about magnetism, the solar photospheric, chromospheric, coronal spectra, as well as earth science and climate. In addition we are developing and will cover topics on ecosystem structure, biomass and water on Earth. We strive to free the non-science undergraduate from the "fear of science" and replace it with the excitement of science such that these future teachers will carry this excitement to their future students. Hands-on experiments, computer simulations, analysis of real NASA data, and vigorous seminar discussions are blended in an inquiry-driven curriculum to instill confident understanding of basic physical science and modern, effective methods for teaching it. The course also demonstrates ways how scientific thinking and hands-on activities could be implemented in the classroom. We have designed this course to provide the non-science student a confident basic understanding of physical science and modern, effective methods for teaching it. Most of topics were selected using National Science Standards and National Mathematics Standards that are addressed in grades K-8. The course focuses on helping education majors: 1) Build knowledge of scientific concepts and processes; 2) Understand the measurable attributes of objects and the units and methods of measurements; 3) Conduct data analysis (collecting, organizing, presenting scientific data, and to predict the result); 4) Use hands-on approaches to teach science; 5) Be familiar with Internet science teaching resources. Here we share our experiences and challenges we face while teaching this course.

Twitter is an extremely high volume platform for user generated contributions regarding any topic. The wealth of content created at real-time in massive quantities calls for automated approaches to identify the topics of the contributions. Such topics can be utilized in numerous ways, such as public opinion mining, marketing, entertainment, and disaster management. Towards this end, approaches to relate single or partial posts to knowledge base items have been proposed. However, in microblogging systems like Twitter, topics emerge from the culmination of a large number of contributions. Therefore, identifying topics based on collections of posts, where individual posts contribute to some aspect of the greater topic is necessary. Models, such as Latent Dirichlet Allocation (LDA), propose algorithms for relating collections of posts to sets of keywords that represent underlying topics. In these approaches, figuring out what the specific topic(s) the keyword sets represent remains as a separate task. Another issue in topic detection is the scope, which is often limited to specific domain, such as health. This work proposes an approach for identifying domain-independent specific topics related to sets of posts. In this approach, individual posts are processed and then aggregated to identify key tokens, which are then mapped to specific topics. Wikipedia article titles are selected to represent topics, since they are up to date, user-generated, sophisticated articles that span topics of human interest. This paper describes the proposed approach, a prototype implementation, and a case study based on data gathered during the heavily contributed periods corresponding to the four US election debates in 2012. The manually evaluated results (0.96 precision) and other observations from the study are discussed in detail.

Showstack, Randy

2012-03-01

An 8 March congressional hearing about the U.S. National Science Foundation's Major Research Equipment and Facilities Construction (NSF MREFC) account focused on fiscal management and accountability of projects in that account and reviewed concerns raised by NSF's Office of Inspector General (OIG). NSF established the MREFC account in 1995 to better plan and manage investments in major equipment and facilities projects, which can cost from tens of millions to hundreds of millions of dollars, and the foundation has funded 17 MREFC projects since then. The Obama administration's proposed fiscal year (FY) 2013 budget includes funding for four MREFC projects: Advanced Laser Gravitational-Wave Observatory (AdvLIGO), Advanced Technology Solar Telescope (ATST), National Ecological Observatory (NEON), and Ocean Observatories Initiative (OOI). The hearing, held by a subcommittee of the House of Representatives' Committee on Science, Space, and Technology, reviewed management oversight throughout the life cycles of MREFC projects and concerns raised in recent OIG reports about the use of budget contingency funds. NSF's February 2012 manual called "Risk management guide for large facilities" states that cost contingency is "that portion of the project budget required to cover `known unknowns,'" such as planning and estimating errors and omissions, minor labor or material price fluctuations, and design developments and changes within the project scope. Committee members acknowledged measures that NSF has made to improve the MREFC oversight process, but they also urged the agency to continue to take steps to ensure better project management.

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.

Doctoral Dissertation Topics in Education: Do They Align with Critical Issues?

Ethan J Allen

2016-11-01

Full Text Available American society faces complex educational issues which impact many facets of its national interests. Institutions of higher education are granting doctoral degrees to educational leaders, but it is not known to what extent their dissertation topics are aligned with both longstanding and critical issues in education. Using a theoretical framework synthesizing Paul and Elder’s critical thinking model and Kuhlthau’s information seeking process, this study examines a set of education doctoral dissertation topical selections and categorizes them by general themes in relationship to many of the recognized educational issues in the United States. Investigators categorized dissertations from four departments within the College of Education of their home institution. The dataset, retrieved from ProQuest Dissertations and Theses Global, consisted of 231 documents published between 2005 and 2014. Through an inter-rater process examining dissertation titles, abstracts, and keywords, the dissertations were assigned critical issue themes culled from nine editions of a college text, and then categorized under a broader topical scheme situated within a well-used educational research website. Findings indicated that most dissertations concentrated in studies that researched problems and issues within schools. Further, some of the issues considered longstanding were not studied by dissertation authors within the sample. For example, privatization of schools and classroom discipline and justice were not selected for study. Findings also suggest new directions for those responsible for dissertation supervision and topic selection. The study adds to the literature on dissertation topic selection that addresses existing educational issues.

In this paper, we present a method that enable both homology-based approach and composition-based approach to further study the functional core (i.e., microbial core and gene core, correspondingly). In the proposed method, the identification of major functionality groups is achieved by generative topic modeling, which is able to extract useful information from unlabeled data. We first show that generative topic model can be used to model the taxon abundance information obtained by homology-based approach and study the microbial core. The model considers each sample as a “document,” which has a mixture of functional groups, while each functional group (also known as a “latent topic”) is a weight mixture of species. Therefore, estimating the generative topic model for taxon abundance data will uncover the distribution over latent functions (latent topic) in each sample. Second, we show that, generative topic model can also be used to study the genome-level composition of “N-mer” features (DNA subreads obtained by composition-based approaches). The model consider each genome as a mixture of latten genetic patterns (latent topics), while each functional pattern is a weighted mixture of the “N-mer” features, thus the existence of core genomes can be indicated by a set of common N-mer features. After studying the mutual information between latent topics and gene regions, we provide an explanation of the functional roles of uncovered latten genetic patterns. The experimental results demonstrate the effectiveness of proposed method.

An author is generally regarded as an individual "who has made substantial intellectual academic contributions to a published study". However, the extent of the contribution that laboratory medicine professionals have made as authors of research papers in high-impact medical journals remains unclear. From 1 January 2004 to 31 March 2009, 4837 original research articles appeared in the: New England Journal of Medicine, Lancet, Annals of Internal Medicine, JAMA and BMJ. Using authorship as an indicator of intellectual contribution, we analyzed articles that included laboratory medicine parameters in their titles in an observational cross-sectional study. We also extracted data regarding radiological topics that were published during the same time within the same journals. Out of 481 articles concerning laboratory medicine topics, 380 provided information on the affiliations of the authors. At least one author from an institution within the field of laboratory medicine was listed in 212 articles (55.8%). Out of 3943 co-authors, only 756 (19.2%) were affiliated with laboratory medicine institutions. Authors from laboratory medicine institutions were listed as the first, last or corresponding authors in 99 articles (26.1%). The comparative proportions for author affiliation from 55 radiology articles were significantly higher, as 72.7% (p=0.026) of articles and 24.8% (p=0.001) of authors indicated an affiliation with a radiology institution. Radiology professionals from 72.7% of the articles were listed as either the first, last or corresponding authors (pgeneral medicine journals.

Microblog sentiment analysis using social and topic context.

2018-01-01

Analyzing massive user-generated microblogs is very crucial in many fields, attracting many researchers to study. However, it is very challenging to process such noisy and short microblogs. Most prior works only use texts to identify sentiment polarity and assume that microblogs are independent and identically distributed, which ignore microblogs are networked data. Therefore, their performance is not usually satisfactory. Inspired by two sociological theories (sentimental consistency and emotional contagion), in this paper, we propose a new method combining social context and topic context to analyze microblog sentiment. In particular, different from previous work using direct user relations, we introduce structure similarity context into social contexts and propose a method to measure structure similarity. In addition, we also introduce topic context to model the semantic relations between microblogs. Social context and topic context are combined by the Laplacian matrix of the graph built by these contexts and Laplacian regularization are added into the microblog sentiment analysis model. Experimental results on two real Twitter datasets demonstrate that our proposed model can outperform baseline methods consistently and significantly.

Topical treatments of skin pain: a general review with a focus on hidradenitis suppurativa with topical agents.

Science.gov (United States)

Scheinfeld, Noah

2014-07-15

Hidradenitis Supprurativa (HS) is a painful chronic follicular disease. Few papers have addressed pain control for this debilitating condition. Possible topical agents include tricyclic antidepressants, opioids, anticonvulsants, NSAIDs, NMDA receptor antagonists, local anesthetics and other agents. The first line agents for the topical treatment of the cutaneous pain of HS are diclonefac gel 1% and liposomal xylocaine 4% and 5% cream or 5% ointment. The chief advantage of topical xylocaine is that is quick acting i.e. immediate however with a limited duration of effect 1-2 hours. The use of topical ketamine, which blocks n-methyl-D-aspartate receptors in a non-competitive fashion, might be a useful tool for the treatment of HS pain. Topical doxepin, which available in a 5% commercially preparation (Zonalon®) , makes patients drowsy and is not useful for controlling the pain of HS . Doxepin is available in a 3% or 3.3% concentration (which causes less drowsiness) from compounding pharmacies and can be used in compounded analgesic preparations with positive effect. Topical doxepin is preferred over use of topical amitriptyline because topical doxepin is more effective. Nevertheless, topical amitriptyline increase of the tactile and mechanical nociceptive thresholds and can be used for topical pain control in compound mixture of analgesics . Gabapentin and pregablin can also be used compounded with other agents in topical analgesic preparations with positive topical anesthetic effect. Capsaicin is not useful for topical treatment of the pain of HS. Sometimes compounded of anesthetics medications such as ketamine 10%, bupivacaine 1%, diclofenac 3%, doxepin 3% or 3.3%, and gabapentin 6% can extend the duration of effect so that medication only needs to be used 2 or 3 times a day. Still in my experience the easiest to get and most patient requested agent is topical diclonefac 1% gel.

2010-05-01

This article discusses the identification, selection, and refinement of topics for comparative effectiveness systematic reviews within the Agency for Healthcare Research and Quality's Effective Health Care (EHC) program. The EHC program seeks to align its research topic selection with the overall goals of the program, impartially and consistently apply predefined criteria to potential topics, involve stakeholders to identify high-priority topics, be transparent and accountable, and continually evaluate and improve processes. A topic prioritization group representing stakeholder and scientific perspectives evaluates topic nominations that fit within the EHC program (are "appropriate") to determine how "important" topics are as considered against seven criteria. The group then judges whether a new comparative effectiveness systematic review would be a duplication of existing research syntheses, and if not duplicative, if there is adequate type and volume of research to conduct a new systematic review. Finally, the group considers the "potential value and impact" of a comparative effectiveness systematic review. As the EHC program develops, ongoing challenges include ensuring the program addresses truly unmet needs for synthesized research because national and international efforts in this arena are uncoordinated, as well as engaging a range of stakeholders in program decisions while also achieving efficiency and timeliness.

Petty, David A; Blaiss, Michael S

2013-01-01

Guidelines from throughout the world recommend intranasal corticosteroids (INSs) as first-line treatment for most patients with moderate to severe allergic rhinitis. In general, limited comparative studies between different INSs have not indicated that one particular steroid moiety is more effective than another in controlling symptoms of allergic rhinitis. However, there are numerous formulations available with different ingredients that may influence a patient's adherence to treatment. This article looks at topical features with these agents, specifically, formulations, vehicles (aqueous vs aerosol), and side effects such as epistaxis and nasal septal perforation. Topical side effects are minimal with INSs with the exception of epistaxis. There are major differences in formulations, volumes, and vehicles between INSs, which could affect adherence. Physicians need to be aware of the different INS attributes to try to match patients' preferences in order to achieve better adherence and improve outcomes in sufferers of allergic rhinitis.

Mental Mechanisms for Topics Identification

Directory of Open Access Journals (Sweden)

Louis Massey

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.

Since society and science need interdisciplinary works, the interesting topic of chaos is chosen for interdisciplinary education in physics. The educational programme contains various university-level activities such as computer simulations, chaos experiment and team projects besides ordinary teaching. According to the participants, the programme seems useful and good. In addition, we discuss some issues which can be important to interdisciplinary education in physics: for example the possible difficulties in programme design, the expertise barriers of non-major fields, the role of non-theoretical education in understanding and the project-type team activities

Full Text Available Drug delivery across the skin is used for several millennia to ease gastrointestinal (GI ailments in Traditional Persian Medicine (TPM. TPM topical remedies are generally being applied on the stomach, lower abdomen, lower back and liver to alleviate GI illnesses such as dyspepsia, gastritis, GI ulcers, inflammatory bowel disease, intestinal worms and infections. The aim of the present study is to survey the topical GI remedies and plant species used as ingredients for these remedies in TPM. In addition, pharmacological activities of the mentioned plants have been discussed. For this, we searched major TPM textbooks to find plants used to cure GI problems in topical use. Additionally, scientific databases were searched to obtain pharmacological data supporting the use of TPM plants in GI diseases. Rosa × damascena, Pistacia lentiscus, Malus domestica, Olea europaea and Artemisia absinthium are among the most frequently mentioned ingredients of TPM remedies. β-asarone, amygdalin, boswellic acids, guggulsterone, crocin, crocetin, isomasticadienolic acid, and cyclotides are the most important phytochemicals present in TPM plants with GI-protective activities. Pharmacological studies demonstrated GI activities for TPM plants supporting their extensive traditional use. These plants play pivotal role in alleviating GI disorders through exhibiting numerous activities including antispasmodic, anti-ulcer, anti-secretory, anti-colitis, anti-diarrheal, antibacterial and anthelmintic properties. Several mechanisms underlie these activities including the alleviation of oxidative stress, exhibiting cytoprotective activity, down-regulation of the inflammatory cytokines, suppression of the cellular signaling pathways of inflammatory responses, improving re-epithelialization and angiogenesis, down-regulation of anti-angiogenic factors, blocking activity of acetylcholine, etc.

Superconcentration and related topics

CERN Document Server

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...

Scarinci, Fabio; Mezzana, Paolo; Pasquini, Paola; Colletti, Michelle; Cacciamani, Andrea

2012-06-01

Minoxidil is one of the drugs approved for the treatment of androgenetic alopecia. This article presents a case of central serous chorioretinopathy after application of topical minoxidil solution. We examined a 37-year-old man who complained of a positive relative scotoma, metamorphopsia and impaired dark adaptation involving the right eye. The patient reported an 8 month history of daily topical use but denied previous treatment with other drugs. Dilated fundus examination of right eye revealed central swelling located over the macula. Optical coherence tomography showed the presence of subretinal fluid. Fluorescein angiography disclosed one focal hyperfluorescent spot in the foveal area with minimal pigmentary changes limitated to that area. The patient was diagnosed with central serous chorioretinopathy (CSC) potentially related to an 8 month topical minoxidil solution administration. One month after the drug was discontinued, normal findings were found upon reexamination. The patient reported no previous episode of CSC. Major systemic side effects from topical solution of minoxidil are rare. To our knowledge, this is the first reported case of a central serous chorioretinopathy associated with long-term use of this drug.

Topical therapies have become an integral component in the management plan for chronic rhinosinusitis (CRS). Several topical therapy strategies have been evaluated, but a formal comprehensive evaluation of the evidence has never been performed. The purpose of this article is to provide an evidence-based approach for the utilization of topical therapies in the management of CRS. A systematic review of the literature was performed and the guidelines for development of an evidence-based review with recommendations were followed. Study inclusion criteria were: adult population >18 years old; chronic rhinosinusitis (CRS) based on published diagnostic criteria; and clearly defined primary clinical end-point. We focused on reporting higher-quality studies (level 2b or higher), but reported on lower-level studies if the topic contained insufficient evidence. We excluded drug-eluting spacer and stent therapy from this review. This review identified and evaluated the literature on 5 topical therapy strategies for CRS: saline irrigation, topical steroid, topical antibiotic, topical antifungal, and topical alternatives (surfactant, manuka honey, and xylitol irrigations). Based on the available evidence, sinonasal saline irrigation and standard topical nasal steroid therapy are recommended in the topical treatment of CRS. Nonstandard (off-label) topical sinonasal steroid therapies can be an option for managing CRS. The evidence recommends against the use of topical antifungal therapy and topical antibiotic therapy delivered using nebulized and spray techniques in routine cases of CRS. There is insufficient clinical research to provide recommendations for alternative therapies or topical antibiotic therapy delivered using other delivery methods (eg, irrigations). © 2013 ARS-AAOA, LLC.

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.

MELODI (Multidisciplinary European Low Dose Initiative) is a European radiation protection research platform with focus on research on health risks after exposure to low-dose ionising radiation. It was founded in 2010 and currently includes 44 members from 18 countries. A major activity of MELODI is the continuous development of a long-term European Strategic Research Agenda (SRA) on low-dose risk for radiation protection. The SRA is intended to identify priorities for national and European radiation protection research programs as a basis for the preparation of competitive calls at the European level. Among those key priorities is the improvement of health risk estimates for exposures close to the dose limits for workers and to reference levels for the population in emergency situations. Another activity of MELODI is to ensure the availability of European key infrastructures for research activities, and the long-term maintenance of competences in radiation research via an integrated European approach for training and education. The MELODI SRA identifies three key research topics in low dose or low dose-rate radiation risk research: (1) dose and dose rate dependence of cancer risk, (2) radiation-induced non-cancer effects and (3) individual radiation sensitivity. The research required to improve the evidence base for each of the three key topics relates to three research lines: (1) research to improve understanding of the mechanisms contributing to radiogenic diseases, (2) epidemiological research to improve health risk evaluation of radiation exposure and (3) research to address the effects and risks associated with internal exposures, differing radiation qualities and inhomogeneous exposures. The full SRA and associated documents can be downloaded from the MELODI website (http://www.melodi-online.eu/sra.html). (orig.)

Correlated Topic Vector for Scene Classification.

Wei, Pengxu; Qin, Fei; Wan, Fang; Zhu, Yi; Jiao, Jianbin; Ye, Qixiang

2017-07-01

Scene images usually involve semantic correlations, particularly when considering large-scale image data sets. This paper proposes a novel generative image representation, correlated topic vector, to model such semantic correlations. Oriented from the correlated topic model, correlated topic vector intends to naturally utilize the correlations among topics, which are seldom considered in the conventional feature encoding, e.g., Fisher vector, but do exist in scene images. It is expected that the involvement of correlations can increase the discriminative capability of the learned generative model and consequently improve the recognition accuracy. Incorporated with the Fisher kernel method, correlated topic vector inherits the advantages of Fisher vector. The contributions to the topics of visual words have been further employed by incorporating the Fisher kernel framework to indicate the differences among scenes. Combined with the deep convolutional neural network (CNN) features and Gibbs sampling solution, correlated topic vector shows great potential when processing large-scale and complex scene image data sets. Experiments on two scene image data sets demonstrate that correlated topic vector improves significantly the deep CNN features, and outperforms existing Fisher kernel-based features.

Off-highway vehicle technology roadmap.; TOPICAL

NONE

2002-01-01

The off-highway sector is under increasing pressure to reduce operating costs (including fuel costs) and to reduce emissions. Recognizing this, the Society of Automotive Engineers and the U.S. Department of Energy (DOE) convened a workshop in April 2001 (ANL 2001) to (1) determine the interest of the off-highway sector (consisting of agriculture, construction, surface mining, inland marine) in crafting a shared vision of off-highway, heavy machines of the future and (2) identify critical research and development (R and D) needs for minimizing off-highway vehicle emissions while cost-effectively maintaining or enhancing system performance. The workshop also enabled government and industry participants to exchange information. During the workshop, it became clear that the challenges facing the heavy, surface-based off-highway sector can be addressed in three major machine categories: (1) engine/aftertreatment and fuels/lubes, (2) machine systems, and (3) thermal management. Working groups convened to address these topical areas. The status of off-highway technologies was determined, critical technical barriers to achieving future emission standards were identified, and strategies and technologies for reducing fuel consumption were discussed. Priority areas for R and D were identified. Given the apparent success of the discussions at the workshop, several participants from industry agreed to help in the formation of a joint industry/government ''roadmap'' team. The U.S. Department of Energy's Office of Heavy Vehicle Technologies has an extensive role in researching ways to make heavy-duty trucks and trains more efficient, with respect to both fuel usage and air emissions. The workshop participants felt that a joint industry/government research program that addresses the unique needs of the off-highway sector would complement the current research program for highway vehicles. With industry expertise, in-kind contributions, and federal government funding (coupled with

Phenotypic topics learned from EHR data can be more stable and transferable than billing codes for characterizing the general status of a patient population. This suggests that EHR-based research may be able to leverage such phenotypic topics as variables when pooling patient populations in predictive models. Copyright © 2015 Elsevier Inc.

Full Text Available This paper reports a research capacity building exercise with a group of CNCs practicing in the speciality of paediatrics in New South Wales (NSW, Australia. It explores the first step in building a research culture, through identifying the research priorities of members of the NSW Child Health Networks Paediatric Clinical Nurse Consultant group, and this forms the major focus of this paper. A nominal group technique (NGT was utilised with sixteen members to identify research topics for investigation which were considered a priority for improving children's health care. The group reviewed and prioritised 43 research topics in children's health which were identified in the literature. As a result of conducting this research prioritisation exercise, the group chose two research topics to investigate: reasons for children representing to the Emergency Department and a comparison of the use of high-flow and low-flow nasal prongs in children with bronchiolitis. The research team will continue to mentor the nurses throughout their research projects which resulted from the NGT. One bridge to leadership development in enhancing patient care is translating knowledge to practice and policy development. This study leads the way for a group of CNCs in paediatric nursing to combine their research capacity and influence clinical knowledge.

Bioinformatics is an interdisciplinary field at the intersection of molecular biology and computing technology. To characterize the field as convergent domain, researchers have used bibliometrics, augmented with text-mining techniques for content analysis. In previous studies, Latent Dirichlet Allocation (LDA) was the most representative topic modeling technique for identifying topic structure of subject areas. However, as opposed to revealing the topic structure in relation to metadata such as authors, publication date, and journals, LDA only displays the simple topic structure. In this paper, we adopt the Tang et al.'s Author-Conference-Topic (ACT) model to study the field of bioinformatics from the perspective of keyphrases, authors, and journals. The ACT model is capable of incorporating the paper, author, and conference into the topic distribution simultaneously. To obtain more meaningful results, we use journals and keyphrases instead of conferences and bag-of-words.. For analysis, we use PubMed to collected forty-six bioinformatics journals from the MEDLINE database. We conducted time series topic analysis over four periods from 1996 to 2015 to further examine the interdisciplinary nature of bioinformatics. We analyze the ACT Model results in each period. Additionally, for further integrated analysis, we conduct a time series analysis among the top-ranked keyphrases, journals, and authors according to their frequency. We also examine the patterns in the top journals by simultaneously identifying the topical probability in each period, as well as the top authors and keyphrases. The results indicate that in recent years diversified topics have become more prevalent and convergent topics have become more clearly represented. The results of our analysis implies that overtime the field of bioinformatics becomes more interdisciplinary where there is a steady increase in peripheral fields such as conceptual, mathematical, and system biology. These results are

Nanotechnology is a rapidly growing discipline that capitalizes on the unique properties of matter engineered on the nanoscale. Vehicles incorporating nanotechnology have led to great strides in drug delivery, allowing for increased active ingredient stability, bioavailability, and site-specific targeting. Botulinum toxin has historically been used for the correction of neurological and neuromuscular disorders, such as torticollis, blepharospasm, and strabismus. Recent dermatological indications have been for the management of axillary hyperhydrosis and facial rhytides. Traditional methods of botulinum toxin delivery have been needle-based. These have been associated with increased pain and cost. Newer methods of botulinum toxin formulation have yielded topical preparations that are bioactive in small pilot clinical studies. While there are some risks associated with topical delivery, the refinement and standardization of delivery systems and techniques for the topical administration of botulinum toxin using nanotechnology is anticipated in the near future.

Applicants to US general surgery residency training programs submit standardized applications. Applicants use the personal statement to express their individual rationale for a career in surgery. Our research explores common topics and gender differences within the personal statements of general surgery applicants. We analyzed the electronic residency application service personal statements of 578 applicants (containing 3,82,405 words) from Liaison Committee on Medical Education-accredited medical schools to a single ACGME-accredited general surgery program using an automated textual analysis program to identify common topics and gender differences. Using a recursive algorithm, the program identified common words and clusters, grouping them into topic classes, which are internally validated. We identified and labeled 8 statistically significant topic classes through independent review: "my story," "the art of surgery," "clinical vignettes," "why I love surgery," "residency program characteristics," "working as a team," "academics and research," and "global health and policy." Although some classes were common to all applications, we also identified gender-specific differences. Notably, women were significantly more likely than men to be represented within the class of "working as a team." (p differences between the statements of men and women. Women were more likely to discuss surgery as a team endeavor while men were more likely to focus on the details of their surgical experiences. Our work mirrors what has been found in social psychology research on gender-based differences in how men and women communicate their career goals and aspirations in other competitive professional situations.

Topical 5-aminolevulinic acid-mediated photodynamic therapy (ALA-PDT) is effective for treatment of human oral precancerous lesions. This animal study aimed to assess whether topical methotrexate (MTX) pretreatment could enhance the therapeutic effect of topical ALA-PDT on hamster buccal pouch precancerous lesions. Twenty hamster buccal pouch precancerous lesions were treated with either topical ALA-PDT with topical MTX pretreatment (topical MTX-ALA-PDT group, n = 10) or topical ALA-PDT alone (topical ALA-PDT group, n = 10). The intracellular protoporphyrin IX (PpIX) level in another 12 precancerous lesions (n = 6 for either the topical MTX-ALA or topical ALA group) was monitored by fluorescence spectroscopy. The intracellular PpIX reached its peak level in precancerous lesions 6.5 hours and 2.5 hours after topical ALA application for the topical MTX-ALA group (5.63-fold higher in the lesion than in the normal mucosa) and topical ALA group (2.42-fold higher in the lesion than in the normal mucosa), respectively. The complete response rate of precancerous lesions was 80% for the topical MTX-ALA-PDT group and 70% for the topical ALA-PDT group. In addition, the topical MTX-ALA-PDT group required a significantly lower mean treatment number (2.1 ± 0.6) to achieve complete response than the topical ALA-PDT group (4.4 ± 1.3, p topical MTX-ALA-PDT group had a lower recurrence rate (12.5%) than the topical ALA-PDT group (28.6%). We conclude that topical MTX-pretreatment can increase intracellular PpIX production in hamster buccal pouch precancerous lesions and significantly improves the outcomes of the precancerous lesions treated with topical ALA-PDT.

The Topic of Life and Death in Verbal Creativity of Adolescents aged 14—16 Years

Directory of Open Access Journals (Sweden)

Hoziev V.B.,

2016-01-01

Full Text Available The paper focuses on how adolescents aged 14—16 years use the topic of life and death in their verbal creativity. The authors carried out an experimental research on the genesis of this process and describe how the topic evolves as a specific new formation of verbal creativity in adolescence. At the center of the research were conditions of verbal creativity. The subjects in three samples (traditional learning; spontaneous development; project-based-learning were asked to write an essay on any topic; these essays were subsequently assessed using content analysis. The outcomes revealed that the topic of life and death is likely to appear in the essays of those adolescents whose reference group is more comfortable psychologically. The literary merit of writing statistically correlates with the effectiveness of verbal creativity acquisition. In its psychological content the topic was actually a challenge, a manifestation of rebellion of a young man, an important attempt to get closer to the hidden boundary of the known, a significant step in initiation.

Topical diclofenac in the treatment of osteoarthritis of the knee

2011-02-01

Full Text Available Niklas Schuelert, Fiona A Russell, Jason J McDougallDepartment of Physiology and Pharmacology, University of Calgary, Calgary, AB, CanadaAbstract: Osteoarthritis (OA is a common disease that affects millions of people worldwide. As there is no cure for OA, drug treatment to relieve symptoms is the main form of management. Nonsteroidal anti-inflammatory drugs (NSAIDs such as diclofenac are the most commonly used drugs to treat knee OA pain. Unfortunately, these agents are associated with gastrointestinal and cardiovascular risks, which limit their chronic use. Topical NSAIDs are emerging as a viable alternative for managing OA pain. Because a pharmacologically effective dose can be restricted to the site of pain, there is superfluous systemic absorption, and the risk of related adverse effects is minimized. This article reviews the currently available preclinical and clinical information on topical diclofenac for the treatment of OA pain, including data from recently published randomized controlled trials regarding the efficacy and safety of topical diclofenac. Most studies confirm topical diclofenac to be as effective as oral diclofenac with significantly reduced side effects; however, the efficacy of NSAIDs is far from optimal, and more research needs to be done to investigate the underlying mechanisms of OA in order to improve treatment options, especially for patients with NSAID-resistant OA pain.Keywords: osteoarthritis, topical diclofenac, NSAID, joint pain

The fundamental properties of small particles and their potential for groundbreaking applications are among the most exciting areas of study in modern physics, chemistry, and materials science. The Clusters, Nanocrystals & Nanostructures Gordon ResearchConference and Gordon Research Seminar synthesize contributions from these inter-related fields that reflect the pivotal role of nano-particles at the interface between these disciplines. Size-dependent optical, electronic, magnetic and catalytic properties offer prospects for applications in many fields, and possible solutions for many of the grand challenges facing energy generation, consumption, delivery, and storage in the 21st century. The goal of the 2013 Clusters, Nanocrystals & Nanostructures Gordon Research Conference and Gordon Research Seminar is to continue the historical interdisciplinary tradition of this series and discuss the most recent advances, basic scientific questions, and emerging applications of clusters, nanocrystals, and nanostructures. The Clusters, Nanocrystals & Nanostructures GRC/GRS traditionally brings together the leading scientific groups that have made significant recent advances in one or more fundamental nanoscience or nanotechnology areas. Broad interests of the DOE BES and Solar Photochemistry Program addressed by this meeting include the areas of solar energy to fuels conversion, new photovoltaic systems, fundamental characterization of nanomaterials, magnetism, catalysis, and quantum physics. The vast majority of speakers and attendees will address either directly the topic of nanotechnology for photoinduced charge transfer, charge transport, and catalysis, or will have made significant contributions to related areas that will impact these fields indirectly. These topics have direct relevance to the mission of the DOE BES since it is this cutting-edge basic science that underpins our energy future.

Recent advances in topical anesthesia

Science.gov (United States)

2016-01-01

Topical anesthetics act on the peripheral nerves and reduce the sensation of pain at the site of application. In dentistry, they are used to control local pain caused by needling, placement of orthodontic bands, the vomiting reflex, oral mucositis, and rubber-dam clamp placement. Traditional topical anesthetics contain lidocaine or benzocaine as active ingredients and are used in the form of solutions, creams, gels, and sprays. Eutectic mixtures of local anesthesia cream, a mixture of various topical anesthetics, has been reported to be more potent than other anesthetics. Recently, new products with modified ingredients and application methods have been introduced into the market. These products may be used for mild pain during periodontal treatment, such as scaling. Dentists should be aware that topical anesthetics, although rare, might induce allergic reactions or side effects as a result of an overdose. Topical anesthetics are useful aids during dental treatment, as they reduce dental phobia, especially in children, by mitigating discomfort and pain. PMID:28879311

Research Ethics with Undergraduates in Summer Research Training Programs

2016-02-01

Many undergraduate research training programs incorporate research ethics into their programs and some are required. Engaging students in conversations around challenging topics such as conflict of interest, cultural and gender biases, what is science and what is normative science can difficult in newly formed student cohorts. In addition, discussing topics with more distant impacts such as science and policy, intellectual property and authorship, can be difficult for students in their first research experience that have more immediate concerns about plagiarism, data manipulation, and the student/faculty relationship. Oregon State University's Research Experience for Undergraduates (REU) in Ocean Sciences: From Estuaries to the Deep Sea as one model for incorporating a research ethics component into summer undergraduate research training programs. Weaved into the 10-week REU program, undergraduate interns participate in a series of conversations and a faculty mentor panel focused on research ethics. Topics discussed are in a framework for sharing myths, knowledge and personal experiences on issues in research with ethical implications. The series follows guidelines and case studies outlined from the text, On Being A Scientist: Responsible Conduct In Research Committee on Science, Engineering, and Public Policy, National Academy of Sciences.

Discriminative Relational Topic Models.

Chen, Ning; Zhu, Jun; Xia, Fei; Zhang, Bo

2015-05-01

Relational topic models (RTMs) provide a probabilistic generative process to describe both the link structure and document contents for document networks, and they have shown promise on predicting network structures and discovering latent topic representations. However, existing RTMs have limitations in both the restricted model expressiveness and incapability of dealing with imbalanced network data. To expand the scope and improve the inference accuracy of RTMs, this paper presents three extensions: 1) unlike the common link likelihood with a diagonal weight matrix that allows the-same-topic interactions only, we generalize it to use a full weight matrix that captures all pairwise topic interactions and is applicable to asymmetric networks; 2) instead of doing standard Bayesian inference, we perform regularized Bayesian inference (RegBayes) with a regularization parameter to deal with the imbalanced link structure issue in real networks and improve the discriminative ability of learned latent representations; and 3) instead of doing variational approximation with strict mean-field assumptions, we present collapsed Gibbs sampling algorithms for the generalized relational topic models by exploring data augmentation without making restricting assumptions. Under the generic RegBayes framework, we carefully investigate two popular discriminative loss functions, namely, the logistic log-loss and the max-margin hinge loss. Experimental results on several real network datasets demonstrate the significance of these extensions on improving prediction performance.

Spatial Relation is one of the important components of Geographical Information Science and Spatial Database. There have been lots of researches on Spatial Relation and many different spatial relations have been proposed. The relationships among these spatial relations such as hierarchy and so on are complex and this brings some difficulties to the applications and teaching of these spatial relations. This paper summaries some common spatial relations, extracts the topic types, association types, resource types of these spatial relations using the technology of Topic Maps, and builds many different relationships among these spatial relations. Finally, this paper utilizes Java and Ontopia to build a topic map among these common spatial relations, forms a complex knowledge network of spatial relations, and realizes the effective management and retrieval of spatial relations.

Rehabilitation Of Stroke Aphasia: Topics Of Research

2017-02-01

Full Text Available Background: Stroke may result in aphasia, an acquired language disorder which affects receptive and expressive language. The symptoms are observed in the auditory-verbal processing, oral expression, written expression and written language processing. As spoken language is the strongest tool of human communication, loss of it may cause great destructive consequences in the social and personal life of the affected individual. People with aphasia (PWA and their carers seek rehabilitation in an effort to remove or reduce the effects. Speech-language pathologists (SLPs are professional in offering such service. This paper aims at addressing new approaches and current research questions about the factors affecting the therapy. Main points: The issues which aphasia therapy research and reviews have addressed are the ones that are asked frequently in clinical settings and research areas. These include the intensity of treatment, the best post-onset time to start, quality of individualized treatment, efficacy of newly-introduced interventions, and the interventions based on the International Classification of Functioning, Disability and Health (ICF model with emphasis on activity/participation. Findings: The results of studies have revealed that compact therapy in a short period of time might result in better recovery of aphasia. Studies also indicated that starting treatments very early with intensive programs leads to the best therapy results. Chronic stage is good for some intervention strategies as well; however, the effectiveness of these interventions requires further investigations. Moreover, better treatment results could be attained by tailoring the program to match with individual needs. Manipulation of word frequency, personal relevance, and considering reaction time are among important factors in tailor-made therapies. Besides, the conceptual model of ICF which incorporates impairment (body structure and function, activity and participation

Full Text Available Topical anesthetics are being widely used in numerous medical and surgical sub-specialties such as anesthesia, ophthalmology, otorhinolaryngology, dentistry, urology, and aesthetic surgery. They cause superficial loss of pain sensation after direct application. Their delivery and effectiveness can be enhanced by using free bases; by increasing the drug concentration, lowering the melting point; by using physical and chemical permeation enhancers and lipid delivery vesicles. Various topical anesthetic agents available for use are eutectic mixture of local anesthetics, ELA-max, lidocaine, epinephrine, tetracaine, bupivanor, 4% tetracaine, benzocaine, proparacaine, Betacaine-LA, topicaine, lidoderm, S-caine patch™ and local anesthetic peel. While using them, careful attention must be paid to their pharmacology, area and duration of application, age and weight of the patients and possible side-effects.

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 ...

Problematic topic transitions in dysarthric conversation.

Bloch, Steven; Saldert, Charlotta; Ferm, Ulrika

2015-01-01

This study examined the nature of topic transition problems associated with acquired progressive dysarthric speech in the everyday conversation of people with motor neurone disease. Using conversation analytic methods, a video collection of five naturally occurring problematic topic transitions was identified, transcribed and analysed. These were extracted from a main collection of over 200 other-initiated repair sequences and a sub-set of 15 problematic topic transition sequences. The sequences were analysed with reference to how the participants both identified and resolved the problems. Analysis revealed that topic transition by people with dysarthria can prove problematic. Conversation partners may find transitions problematic not only because of speech intelligibility but also because of a sequential disjuncture between the dysarthric speech turn and whatever topic has come prior. In addition the treatment of problematic topic transition as a complaint reveals the potential vulnerability of people with dysarthria to judgements of competence. These findings have implications for how dysarthria is conceptualized and how specific actions in conversation, such as topic transition, might be suitable targets for clinical intervention.

The keyword-based entity search restricts search space based on the preference of search. When given keywords and preferences are not related to the same biomedical topic, existing biomedical Linked Data search engines fail to deliver satisfactory results. This research aims to tackle this issue by supporting an inter-topic search-improving search with inputs, keywords and preferences, under different topics. This study developed an effective algorithm in which the relations between biomedical entities were used in tandem with a keyword-based entity search, Siren. The algorithm, PERank, which is an adaptation of Personalized PageRank (PPR), uses a pair of input: (1) search preferences, and (2) entities from a keyword-based entity search with a keyword query, to formalize the search results on-the-fly based on the index of the precomputed Individual Personalized PageRank Vectors (IPPVs). Our experiments were performed over ten linked life datasets for two query sets, one with keyword-preference topic correspondence (intra-topic search), and the other without (inter-topic search). The experiments showed that the proposed method achieved better search results, for example a 14% increase in precision for the inter-topic search than the baseline keyword-based search engine. The proposed method improved the keyword-based biomedical entity search by supporting the inter-topic search without affecting the intra-topic search based on the relations between different entities.

Communication Capacity Research in the Majority World: Supporting the human right to communication specialist services.

Science.gov (United States)

Hopf, Suzanne C

2018-02-01

Receipt of accessible and appropriate specialist services and resources by all people with communication and/or swallowing disability is a human right; however, it is a right rarely achieved in either Minority or Majority World contexts. This paper considers communication specialists' efforts to provide sustainable services for people with communication difficulties living in Majority World countries. The commentary draws on human rights literature, particularly Article 19 of the Universal Declaration of Human Rights and the Communication Capacity Research program that includes: (1) gathering knowledge from policy and literature; (2) gathering knowledge from the community; (3) understanding speech, language and literacy use and proficiency; and (4) developing culturally and linguistically appropriate resources and assessments. To inform the development of resources and assessments that could be used by speech-language pathologists as well as other communication specialists in Fiji, the Communication Capacity Research program involved collection and analysis of data from multiple sources including 144 community members, 75 school students and their families, and 25 teachers. The Communication Capacity Research program may be applicable for achieving the development of evidence-based, culturally and linguistically sustainable SLP services in similar contexts.

Topical immunomodulators in dermatology

Directory of Open Access Journals (Sweden)

Khandpur Sujay

2004-04-01

Full Text Available Topical immunomodulators are agents that regulate the local immune response of the skin. They are now emerging as the therapy of choice for several immune-mediated dermatoses such as atopic dermatitis, contact allergic dermatitis, alopecia areata, psoriasis, vitiligo, connective tissue disorders such as morphea and lupus erythematosus, disorders of keratinization and several benign and malignant skin tumours, because of their comparable efficacy, ease of application and greater safety than their systemic counterparts. They can be used on a domiciliary basis for longer periods without aggressive monitoring. In this article, we have discussed the mechanism of action, common indications and side-effects of the commonly used topical immunomodulators, excluding topical steroids. Moreover, newer agents, which are still in the experimental stages, have also been described. A MEDLINE search was undertaken using the key words "topical immunomodulators, dermatology" and related articles were also searched. In addition, a manual search for many Indian articles, which are not indexed, was also carried out. Wherever possible, the full article was reviewed. If the full article could not be traced, the abstract was used.

Recent Advances In Topical Therapy In Dermatology

Directory of Open Access Journals (Sweden)

Mohan Thappa Devinder

2003-01-01

Full Text Available With changing times various newer topical agents are introduced in the field of dermatology. Tacrolimus and pimecrolimus are immunisuppressants, which are effective topically and are tried in the management of atopic dermatitis as well as other disorders including allergic contact dermatitis, atrophic lichen planus, pyoderma gangrenosum. Imiquimod, an immune response modifier, is presently in use for genital warts but has potentials as anti- tumour agent and in various other dermatological conditions when used topically. Tazarotene is a newer addition to the list of topical reginoids, which is effective in psoriasis and has better effect in combination with calcipotriene, phototherapy and topical costicosteroids. Tazarotene and adapelene are also effective in inflammatory acne. Calcipotriol, a vitamin D analogue has been introduced as a topical agent in the treatment of psoriasis. Steroid components are also developed recently which will be devoid of the side effects but having adequate anti-inflammatory effect. Topical photodynamic therapy has also a wide range of use in dermatology. Newer topical agents including cidofovir, capsaicin, topical sensitizers, topical antifungal agents for onychomycosis are also of use in clinical practice. Other promising developments include skin substitutes and growth factors for wound care.

Farahnik, Benjamin; Sharma, Divya; Alban, Joseph; Sivamani, Raja K

2017-08-01

Patients with psoriasis often enquire about the use of numerous botanical therapeutics. It is important for dermatologists to be aware of the current evidence regarding these agents. We conducted a systematic literature search using the PubMed, MEDLINE, and EMBASE databases for controlled and uncontrolled clinical trials that assessed the use of topical botanical therapeutics for psoriasis. The search included the following keywords: 'psoriasis' and 'plant' or 'herbal' or 'botanical'. We also reviewed citations within articles to identify additional relevant sources. We then further refined the results by route of administration and the topical botanical agents are reviewed herein. A total of 27 controlled and uncontrolled clinical trials addressing the use of topical botanical agents for psoriasis were assessed in this review. We found that the most highly studied and most efficacious topical botanical therapeutics were Mahonia aquifolium, indigo naturalis, aloe vera, and, to a lesser degree, capsaicin. The most commonly reported adverse effects were local skin irritation, erythema, pruritus, burning, and pain. However, the overall evidence for these therapeutics remains limited in quantity and quality. The literature addresses a large number of studies in regard to botanicals for the treatment of psoriasis. While most agents appear to be safe, further research is necessary before topical botanical agents can be consistently recommended to patients.

2017-11-01

Full Text Available A bibliometric analysis based on Scopus database was performed to identify the global research trends related to Supported Ionic Liquid Membranes (SILMs during the time period from 1995 to 2015. This work tries to improve the understanding of the most relevant research topics and applications. The results from the analysis reveal that only after 2005 the research efforts focused on SILMs became significant, since the references found before that year are scarce. The most important research works on the four main application groups for SILMs defined in this work (carbon dioxide separation, other gas phase separations, pervaporation and liquid phase separations were summarized in this paper. Carbon dioxide separation appeared as the application that has received by far the most attention according to the research trends during the analysed period. Comments about other significant applications that are gaining attention, such as the employment of SILMs in analytical tasks or their consideration for the production of fuel cells, have been included.

Self-medication is a common habit in our country; Nigeria, especially among patients with otorhinolaryngological disorders. Medication when taken wrongly may bring dire consequences to the individual, such as masking developing diseases and may cause many other undesirable effects. The aim of this study was to determine the prevalence and to analyze topical ear drop self-medication practices among respondents attending the Ear, Nose, and Throat Clinic of Federal Teaching Hospital Ido Ekiti, Nigeria. A 6-month hospital based cross-sectional study was conducted among patients who were seen in the Ear, Nose, and Throat facility of Federal Teaching Hospital, Ido Ekiti from July to December 2016 to determine topical ear drop self-medication practices. A pretested semi-structured questionnaire was used to obtained information from respondents. A total of 162 respondents out of 493 patients seen during the study had otological problems. Of which 107 (66%) respondents had engaged in self-medication with topical ear drops. Their ages ranged between 2 and 83 years with a mean age of 36.6 ± 19.1 years. There were 75 males and 87 females. The major reason for self-medication was that their ailments were minor in about 40.2% and the most common indication for self-medication was ear blockage with hearing impairment (33.6%). Pharmacy/chemist shops (42%) were major sources of information for those that self-medicated. Chloramphenicol and gentamycin were the major drugs that were used by the respondents. Majority of the respondents in this study practiced self-medication using different topical ear drops. Major source of information on the topical ear drops used was from pharmacy/chemist shops. There is a need for adequate public health education to create awareness among people on the danger of self-medication and to enact or enforce the law to reduce access to over the counter drugs. Healthcare should be made available and avoidable at primary health-care level.

Quantitative data are lacking on the profile of published research in aromatherapy. The objective of the study was to investigate the profile of original and review articles under the topic aromatherapy using bibliometric analysis. Articles on aromatherapy, published between 1995 and 2014, were retrieved from the Science Citation Index-Expanded database from the Web of Science. The records extracted were analyzed for citation characteristics, including the distribution of publication years, languages, countries or regions, journals, articles, and authors using HistCite 12.03.17. VOSviewer v.1.61 was used to construct bibliometric diagrams. A total of 549 original and review articles, published in 287 different peer-reviewed journals by 1888 authors, were identified. There was a steady increase in the number of published articles from 1995 to 2014. The majority of the articles was written in English (95.8%) and the United States was the leading country in the total number of published articles (n = 107, 19.5%) Journal of Alternative and Complementary Medicine published the greatest number of articles on the topic (n = 31, 5.6%). The article that received the greatest number of citations was published in Complementary Therapies in Medicine. Visualization analysis based on co-occurrences of words in the title and abstract revealed three clusters of research topics, including essential oil, intervention, and complementary medicine. This study provided a systematic overview of productivity and visibility of research work in aromatherapy and the findings could be used for organizing and prioritizing future research efforts in aromatherapy research.

Proceedings of the international symposium on research reactor safety operations and modifications

International Nuclear Information System (INIS)

1990-03-01

The International Symposium on Research Reactor Safety, Operations and Modifications was organized by the International Atomic Energy Agency in cooperation with Atomic Energy of Canada Limited-Research Company. The main objectives of this Symposium were: (1) to exchange information and to discuss current perspectives and concerns relating to all aspects to research reactor safety, operations, and modifications; and, (2) to present views and to discuss future initiatives and directions for research reactor design, operations, utilization, and safety. The symposium topics included: research reactor programmes and experience; research reactor design safety and analysis; research reactor modifications and decommissioning; research reactor licensing; and new research reactors. These topics were covered during eight oral sessions and three poster sessions. These Proceedings include the full text of the 93 papers presented. The subject of Symposium was quite wide-ranging in that it covered essentially all aspects of research reactor safety, operations, and modifications. This was considered to be appropriate and timely given the 326 research reactors currently in operation in some 56 countries; given the degree of their utilization which ranges from pure and applied research to radioisotopes production to basic training and manpower development; and given that many of these reactors are undergoing extensive modifications, core conversions, power upratings, and are becoming the subject of safety reassessment and regulatory reviews. Although the Symposium covered many topics, the majority of papers and discussions tended to focus mainly on research reactor safety. This was seen as a clear sign of the continuing recognition of the fundamental importance of identifying and addressing, particularly through international cooperation, issues and concerns associated with research reactor safety

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

Evaluating the biomedical literature and health-related websites for quality are challenging information retrieval tasks. Current commonly used methods include impact factor for journals, PubMed's clinical query filters and machine learning-based filter models for articles, and PageRank for websites. Previous work has focused on the average performance of these methods without considering the topic, and it is unknown how performance varies for specific topics or focused searches. Clinicians, researchers, and users should be aware when expected performance is not achieved for specific topics. The present work analyzes the behavior of these methods for a variety of topics. Impact factor, clinical query filters, and PageRank vary widely across different topics while a topic-specific impact factor and machine learning-based filter models are more stable. The results demonstrate that a method may perform excellently on average but struggle when used on a number of narrower topics. Topic-adjusted metrics and other topic robust methods have an advantage in such situations. Users of traditional topic-sensitive metrics should be aware of their limitations.

Medical mycology and fungal immunology: new research perspectives addressing a major world health challenge.

Science.gov (United States)

Gow, Neil A R; Netea, Mihai G

2016-12-05

Fungi cause more than a billion skin infections, more than 100 million mucosal infections, 10 million serious allergies and more than a million deaths each year. Global mortality owing to fungal infections is greater than for malaria and breast cancer and is equivalent to that owing to tuberculosis (TB) and HIV. These statistics evidence fungal infections as a major threat to human health and a major burden to healthcare budgets worldwide. Those patients who are at greatest risk of life-threatening fungal infections include those who have weakened immunity or have suffered trauma or other predisposing infections such as HIV. To address these global threats to human health, more research is urgently needed to understand the immunopathology of fungal disease and human disease susceptibility in order to augment the advances being made in fungal diagnostics and drug development. Here, we highlight some recent advances in basic research in medical mycology and fungal immunology that are beginning to inform clinical decisions and options for personalized medicine, vaccine development and adjunct immunotherapies.This article is part of the themed issue 'Tackling emerging fungal threats to animal health, food security and ecosystem resilience'. © 2016 The Authors.

Corporate governance, ownership and control: A review of recent scholarly research

Directory of Open Access Journals (Sweden)

Alex Kostyuk

2018-01-01

Full Text Available This manuscript is aimed at highlighting the most recent trends in corporate governance, ownership and control based on the manuscripts presented at the international conference “Corporate Governance, Ownership and Control” that took place in Rome on February 27, 2018. We have also used reputable papers published in the relevant academic journals in the past to support the arguments stated by the authors of the papers, presented at the conference. This paper covers a wide range of corporate governance topics in corporate ownership and control toward corporate governance mechanisms, such as board of directors, the board diversity, directors’ remuneration, firm performance, auditing and accounting, etc. We saw a growing interest of researchers to widen the scope of their major research to link it to corporate ownership and control issues. Currently, corporate governance research follows two major routs: classical empirical corporate governance research and multidisciplinary research aimed at findings non-conventional methods to solution of existing problems.

When the topic is you: genetic counselor responses to prenatal patients' requests for self-disclosure.

Science.gov (United States)

Balcom, Jessica R; Veach, Patricia McCarthy; Bemmels, Heather; Redlinger-Grosse, Krista; LeRoy, Bonnie S

2013-06-01

A limited amount of research indicates patient requests play a major role in genetic counselors' self-disclosure decisions and that disclosure and non-disclosure responses to patient requests may differentially affect genetic counseling processes. Studies further suggest patient requests may be more common in prenatal settings, particularly when counselors are pregnant. Empirical evidence is limited however, concerning the nature of patient requests. This study explored genetic counselors' experiences of prenatal patients' requests for self-disclosure. Four major research questions were: (1) What types of questions do prenatal patients ask that invite self-disclosure?; (2) Do pregnant genetic counselors have unique experiences with prenatal patient disclosure requests?; (3) How do genetic counselors typically respond to disclosure requests?; and (4) What strategies are effective and ineffective in responding to disclosure requests? One hundred seventy-six genetic counselors completed an online survey and 40 also participated in telephone interviews. Inductive analysis of 21 interviews revealed patient questions vary, although questions about counselor demographics are most common, and patients are more likely to ask pregnant counselors questions about their personal pregnancy decisions. Participants reported greater discomfort with self-disclosure requests during pregnancy, yet also disclosing more frequently during pregnancy. Counselor responses included personal self-disclosure, professional self-disclosure, redirection, and declining to disclose. Factors perceived as influencing disclosure included: topic, patient motivations, timing of request, quality of counseling relationship, patient characteristics, and ethical/legal responsibilities. Disclosure practices changed over time for most counselors. Additional findings, practice implications, and research recommendations are discussed.

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.

Under the Top-level Research Initiative, Gudmund Hernes, researcher, professor of sociology and former Norwegian minister, sets out assertions and theses as a basis for debate - and in time political action. How do we respond when we are faced with the repercussions of our interactions with nature? The aim of this report is to mobilise the social science disciplines. Only when we understand how and why we have reacted so far can we take effective action. From table of content: I. Introduction, II. The ''Ecological Revolution'', III. Seven events that changed the world, IV. Explanations of attitude change, V. Some topics for research (eb)

1991-01-01

Topics in Lightwave Transmission Systems is a second volume of a treatise on optical fiber communications that is devoted to the science, engineering, and application of information transmission via optical fibers. The first volume, published in 1985, dealt exclusively with fiber fabrication. The present volume contains topics that pertain to subsystems and systems. The book contains five chapters and begins with discussions of transmitters and receivers, which are basic to systems now operating in the field. Subsequent chapters cover topics relating to coherent systems: frequency and phase m

Towards Non-prescriptive Issues: a Teaching Framework for Selecting Marketing Dissertation Topics

OpenAIRE

Horan, Conor

2006-01-01

There is a significant absence in academic literature, textbooks and practical teaching tools for advising or guiding student learning, in a practical non-prescriptive manner, toward topic selection and development. Prescriptive or rational approaches, taken by many research methods textbooks, are not adequate or sufficient when teaching this important first stage in the research process. Non-prescriptive approaches describing manageable steps should be researched more to fill this pedagogic ...

Each of these topics is discussed in detail in this book

Design Topics for Superconducting RF Cavities and Ancillaries

International Nuclear Information System (INIS)

Padamsee, H

2014-01-01

RF superconductivity has become a major subfield of accelerator science. There has been an explosion in the number of accelerator applications and in the number of laboratories engaged. The first lecture at this meeting of the CAS presented a review of fundamental design principles to develop cavity geometries to accelerate velocity-of-light particles (β = v/c ~ 1), moving on to the corresponding design principles for medium-velocity (medium-β) and low-velocity (low-β) structures. The lecture included mechanical design topics. The second lecture dealt with input couplers, higher-order mode extraction couplers with absorbers, and tuners of both the slow and fast varieties

Information retrieval for systematic reviews in food and feed topics: A narrative review.

Wood, Hannah; O'Connor, Annette; Sargeant, Jan; Glanville, Julie

2018-01-09

Systematic review methods are now being used for reviews of food production, food safety and security, plant health, and animal health and welfare. Information retrieval methods in this context have been informed by human health-care approaches and ideally should be based on relevant research and experience. This narrative review seeks to identify and summarize current research-based evidence and experience on information retrieval for systematic reviews in food and feed topics. MEDLINE (Ovid), Science Citation Index (Web of Science), and ScienceDirect (http://www.sciencedirect.com/) were searched in 2012 and 2016. We also contacted topic experts and undertook citation searches. We selected and summarized studies reporting research on information retrieval, as well as published guidance and experience. There is little published evidence on the most efficient way to conduct searches for food and feed topics. There are few available study design search filters, and their use may be problematic given poor or inconsistent reporting of study methods. Food and feed research makes use of a wide range of study designs so it might be best to focus strategy development on capturing study populations, although this also has challenges. There is limited guidance on which resources should be searched and whether publication bias in disciplines relevant to food and feed necessitates extensive searching of the gray literature. There is some limited evidence on information retrieval approaches, but more research is required to inform effective and efficient approaches to searching to populate food and feed reviews.

A systematic review of the evidence for topical use of ginger.

2013-01-01

The use of ginger as a topical intervention is widely advocated in the popular media. However, there has been no attempt to date to synthesize the evidence for topically administered ginger. To systematically review and synthesize the best available evidence of effectiveness for topical ginger in any condition. CAM on PubMed, CINAHL, Google Scholar, MEDLINE, National Library of Australia, The Cochrane Library, TRIP, pertinent texts, and bibliographies of relevant papers. Data sources were systematically searched for studies investigating the clinical effectiveness of topical ginger, in any form and for any condition, regardless of study design. Studies were limited to those published between 1980 and 2010, and published in English, Mandarin, Cantonese, or Taiwanese. Data were extracted by two authors, independently, using standardized templates. Four studies met the inclusion criteria, including three randomized controlled trials and one non-randomized controlled trial. All studies differed in terms of study population, outcome measures, comparative interventions, and dose and form of ginger used, and thus, were not amenable to meta-analysis. Findings from all trials favored usage of ginger for most outcomes. However, the small sample sizes and inadequate methodological reporting indicate a high risk of bias and the need for caution when interpreting these results. Few studies have investigated the effectiveness of topically administered ginger for any condition. Until the findings of these studies are corroborated by more robust research, and the safety of ginger is adequately established, clinicians should remain cautious about using topical ginger in clinical practice. © 2013 Elsevier Inc.
