To ascertain the number, type, and overall usage of statistics in American Journal of Orthodontics and Dentofacial (AJODO) articles for 2008. These data were then compared to data from three previous years: 1975, 1985, and 2003. The frequency and distribution of statistics used in the AJODO original articles for 2008 were dichotomized into those using statistics and those not using statistics. Statistical procedures were then broadly divided into descriptive statistics (mean, standard deviation, range, percentage) and inferential statistics (t-test, analysis of variance). Descriptive statistics were used to make comparisons. In 1975, 1985, 2003, and 2008, AJODO published 72, 87, 134, and 141 original articles, respectively. The percentage of original articles using statistics was 43.1% in 1975, 75.9% in 1985, 94.0% in 2003, and 92.9% in 2008; original articles using statistics stayed relatively the same from 2003 to 2008, with only a small 1.1% decrease. The percentage of articles using inferential statistical analyses was 23.7% in 1975, 74.2% in 1985, 92.9% in 2003, and 84.4% in 2008. Comparing AJODO publications in 2003 and 2008, there was an 8.5% increase in the use of descriptive articles (from 7.1% to 15.6%), and there was an 8.5% decrease in articles using inferential statistics (from 92.9% to 84.4%).

The CAREM reactor and present currents in reactor design

International Nuclear Information System (INIS)

Ordonez, J.P.

1990-01-01

INVAP has been working on the CAREM project since 1983. It concerns a very low power reactor for electrical energy generation. The design of the reactor and the basic criteria used were described in 1984. Since then, a series of designs have been presented for reactors which are similar to CAREM regarding the solutions presented to reduce the chance of major nuclear accidents. These designs have been grouped under different names: Advanced Reactors, Second Generation Reactors, Inherently Safe Reactors, or even, Revolutionary Reactors. Every reactor fabrication firm has, at least, one project which can be placed in this category. Presently, there are two main currents of Reactor Design; Evolutionary and Revolutionary. The present work discusses characteristics of these two types of reactors, some revolutionary designs and common criteria to both types. After, these criteria are compared with CAREM reactor design.

Molecular biology and literature databases represent essential infrastructure for life science research. Effective integration of these data resources requires that there are structured cross-references at the level of individual articles and biological records. Here, we describe the current patterns of how database entries are cited in research articles, based on analysis of the full text Open Access articles available from Europe PMC. Focusing on citation of entries in the European Nucleotide Archive (ENA), UniProt and Protein Data Bank, Europe (PDBe), we demonstrate that text mining doubles the number of structured annotations of database record citations supplied in journal articles by publishers. Many thousands of new literature-database relationships are found by text mining, since these relationships are also not present in the set of articles cited by database records. We recommend that structured annotation of database records in articles is extended to other databases, such as ArrayExpress and Pfam, entries from which are also cited widely in the literature. The very high precision and high-throughput of this text-mining pipeline makes this activity possible both accurately and at low cost, which will allow the development of new integrated data services.

Full Text Available Abstract Background There is little evidence regarding the comparative quality of abstracts and articles in medical education research. The Medical Education Research Study Quality Instrument (MERSQI, which was developed to evaluate the quality of reporting in medical education, has strong validity evidence for content, internal structure, and relationships to other variables. We used the MERSQI to compare the quality of reporting for conference abstracts, journal abstracts, and published articles. Methods This is a retrospective study of all 46 medical education research abstracts submitted to the Society of General Internal Medicine 2009 Annual Meeting that were subsequently published in a peer-reviewed journal. We compared MERSQI scores of the abstracts with scores for their corresponding published journal abstracts and articles. Comparisons were performed using the signed rank test. Results Overall MERSQI scores increased significantly for published articles compared with conference abstracts (11.33 vs 9.67; P < .001 and journal abstracts (11.33 vs 9.96; P < .001. Regarding MERSQI subscales, published articles had higher MERSQI scores than conference abstracts in the domains of sampling (1.59 vs 1.34; P = .006, data analysis (3.00 vs 2.43; P < .001, and validity of evaluation instrument (1.04 vs 0.28; P < .001. Published articles also had higher MERSQI scores than journal abstracts in the domains of data analysis (3.00 vs 2.70; P = .004 and validity of evaluation instrument (1.04 vs 0.26; P < .001. Conclusions To our knowledge, this is the first study to compare the quality of medical education abstracts and journal articles using the MERSQI. Overall, the quality of articles was greater than that of abstracts. However, there were no significant differences between abstracts and articles for the domains of study design and outcomes, which indicates that these MERSQI elements may be applicable to abstracts.

Brychan Thomas

2012-01-01

Full Text Available The aim of the paper is to elucidate a systematic approach to convert a Masters dissertation into a journal article. This approach has involved a fundamental thematic review of the literature concerning the conversion of dissertations into journal articles. From these sources pertinent approaches, processes, lessons, and guidance have been noted and analysed. By undertaking this distillation of relevant material, to enable the efficient conversion of dissertations into journal articles, appropriate procedures and conclusions have been compiled. Findings present current thinking on the conversion of a dissertation into a journal paper in terms of how dissertations differ from journal articles, reframing for publication, rethinking the material, trimming the length, time taken to rewrite the material, specific lessons, and adapting for publication. Recommendations provided in the paper will enable staff to take this course of action when developing their publication portfolio to become more research active and to make an important contribution to the publication output of their department/school/faculty, especially with regard to assessment exercises such as the Research Excellence Framework. The value of the paper is that by following appropriate approaches, processes, and procedures it is possible to convert a good dissertation into a ranked journal article.

Folklore in China: Past, Present, and Challenges

Directory of Open Access Journals (Sweden)

Juwen Zhang

2018-04-01

Full Text Available This article first outlines the long history of folklore collection in China, and then describes the disciplinary development in the 20th century. In Section 3, it presents the current situation in terms of disciplinary infrastructure, development, contribution, and challenge, with a focus on the recent practice of safeguarding Intangible Cultural Heritage. These accounts are largely based on the views of the Chinese folklorists. In the final section, this article discusses the issues of cultural continuity, integration, and self-healing mechanisms in Chinese culture by putting Chinese folkloristics in a historical and world perspective. This paper suggests that, to understand Chinese folklore and culture, one must be aware of the most basic differences between Chinese fundamental beliefs and values and those of the West, and that Chinese folklore and folkloristics present new challenges to the current paradigms put forward in the post-colonial, post-modern, and imperial ideologies.

Prevezanos, Panagiotis; Tsolakis, Apostolos I; Christou, Panagiotis

2018-01-01

Identification of highly cited articles based on the h-index and its properties is important for the evaluation of the past, present, and future of any research discipline. In this study, we aimed to identify the h-classic articles in orthodontics. One search on the Web of Science identified all articles from 2000 to 2015 in the 89 journals indexed by the 2015 InCites Journal Citation Reports in the scientific area "dentistry, oral surgery, and medicine." A second search was performed in the Web of Science using all mesh terms related to orthodontics. Then, we applied the h-classic method to select the recent articles with the greatest scientific impact in orthodontics. Eighty articles were considered as h-classic articles. They were published in 20 of the 89 dental journals of the 2015 InCites Journal Citation Reports list. Only 36 articles appeared in orthodontic journals: 23 in the American Journal of Orthodontics & Dentofacial Orthopedics (28.8%), 7 in The Angle Orthodontist (8.8%), and 6 in European Journal of Orthodontics (7.5%). Thirty-eight articles originated from Europe, 28 from the Americas, and 14 from the Middle East and Asia. More than half of fundamental orthodontic research is published in nonorthodontic journals showing that our field is currently limited, and interactions with other research fields should be sought to increase orthodontic research importance and appeal.

BreakingNews: Article Annotation by Image and Text Processing.

Science.gov (United States)

Ramisa, Arnau; Yan, Fei; Moreno-Noguer, Francesc; Mikolajczyk, Krystian

2018-05-01

Building upon recent Deep Neural Network architectures, current approaches lying in the intersection of Computer Vision and Natural Language Processing have achieved unprecedented breakthroughs in tasks like automatic captioning or image retrieval. Most of these learning methods, though, rely on large training sets of images associated with human annotations that specifically describe the visual content. In this paper we propose to go a step further and explore the more complex cases where textual descriptions are loosely related to the images. We focus on the particular domain of news articles in which the textual content often expresses connotative and ambiguous relations that are only suggested but not directly inferred from images. We introduce an adaptive CNN architecture that shares most of the structure for multiple tasks including source detection, article illustration and geolocation of articles. Deep Canonical Correlation Analysis is deployed for article illustration, and a new loss function based on Great Circle Distance is proposed for geolocation. Furthermore, we present BreakingNews, a novel dataset with approximately 100K news articles including images, text and captions, and enriched with heterogeneous meta-data (such as GPS coordinates and user comments). We show this dataset to be appropriate to explore all aforementioned problems, for which we provide a baseline performance using various Deep Learning architectures, and different representations of the textual and visual features. We report very promising results and bring to light several limitations of current state-of-the-art in this kind of domain, which we hope will help spur progress in the field.

Honorary authorship epidemic in scholarly publications? How the current use of citation-based evaluative metrics make (pseudo)honorary authors from honest contributors of every multi-author article.

Science.gov (United States)

Kovacs, Jozsef

2013-08-01

The current use of citation-based metrics to evaluate the research output of individual researchers is highly discriminatory because they are uniformly applied to authors of single-author articles as well as contributors of multi-author papers. In the latter case, these quantitative measures are counted, as if each contributor were the single author of the full article. In this way, each and every contributor is assigned the full impact-factor score and all the citations that the article has received. This has a multiplication effect on each contributor's citation-based evaluative metrics of multi-author articles, because the more contributors an article has, the more undeserved credit is assigned to each of them. In this paper, I argue that this unfair system could be made fairer by requesting the contributors of multi-author articles to describe the nature of their contribution, and to assign a numerical value to their degree of relative contribution. In this way, we could create a contribution-specific index of each contributor for each citation metric. This would be a strong disincentive against honorary authorship and publication cartels, because it would transform the current win-win strategy of accepting honorary authors in the byline into a zero-sum game for each contributor.

Passage-Based Bibliographic Coupling: An Inter-Article Similarity Measure for Biomedical Articles

Science.gov (United States)

Liu, Rey-Long

2015-01-01

Biomedical literature is an essential source of biomedical evidence. To translate the evidence for biomedicine study, researchers often need to carefully read multiple articles about specific biomedical issues. These articles thus need to be highly related to each other. They should share similar core contents, including research goals, methods, and findings. However, given an article r, it is challenging for search engines to retrieve highly related articles for r. In this paper, we present a technique PBC (Passage-based Bibliographic Coupling) that estimates inter-article similarity by seamlessly integrating bibliographic coupling with the information collected from context passages around important out-link citations (references) in each article. Empirical evaluation shows that PBC can significantly improve the retrieval of those articles that biomedical experts believe to be highly related to specific articles about gene-disease associations. PBC can thus be used to improve search engines in retrieving the highly related articles for any given article r, even when r is cited by very few (or even no) articles. The contribution is essential for those researchers and text mining systems that aim at cross-validating the evidence about specific gene-disease associations. PMID:26440794

Full Text Available A review of the top-cited articles in a scientific discipline can identify areas of research that are well established and those in need of further development, and may, as a result, inform and direct future research efforts. Our objective was to identify and characterize the top-cited articles in traumatic brain injury (TBI. We used publically available software to identify the 50 TBI articles with the most lifetime citations, and the 50 TBI articles with the highest annual citation rates. A total of 73 articles were included in this review, with 27 of the 50 papers with the highest annual citation rates common to the cohort of 50 articles with the most lifetime citations. All papers were categorized by their primary topic or focus, namely: predictor of outcome, pathology/natural history, treatment, guidelines and consensus statements, epidemiology, assessment measures, or experimental model of TBI. The mean year of publication of the articles with the most lifetime citations and highest annual citation rates was, respectively, 1990 ± 14.9 years and 2003 ± 6.7 years. The 50 articles with the most lifetime citations typically studied predictors of outcome (34.0%, 17/50 and were specific to severe TBI (38.0%, 19/50. In contrast, the most common subject of papers with the highest annual citation rates was treatment of brain injury (22.0%, 11/50, and these papers most frequently investigated mild TBI (36.0%, 18/50. These findings suggest an intensified focus on mild TBI, which is perhaps a response to the dedicated attention these injuries are currently receiving in the context of sports and war, and because of their increasing incidence in developing nations. Our findings also indicate increased focus on treatment of TBI, possibly due to the limited efficacy of current interventions for TBI. This review provides a cross-sectional summary of some of the most influential articles in TBI, and a bibliometric examination of the current status of TBI

Comparison of SAR and induced current densities in adults and children exposed to electromagnetic fields from electronic article surveillance devices

Martínez-Búrdalo, M.; Sanchis, A.; Martín, A.; Villar, R.

2010-02-01

Electronic article surveillance (EAS) devices are widely used in most stores as anti-theft systems. In this work, the compliance with international guidelines in the human exposure to these devices is analysed by using the finite-difference time-domain (FDTD) method. Two sets of high resolution numerical phantoms of different size (REMCOM/Hershey and Virtual Family), simulating adult and child bodies, are exposed to a 10 MHz pass-by panel-type EAS consisting of two overlapping current-carrying coils. Two different relative positions between the EAS and the body (frontal and lateral exposures), which imply the exposure of different parts of the body at different distances, have been considered. In all cases, induced current densities in tissues of the central nervous system and specific absorption rates (SARs) are calculated to be compared with the limits from the guidelines. Results show that induced current densities are lower in the case of adult models as compared with those of children in both lateral and frontal exposures. Maximum SAR values calculated in lateral exposure are significantly lower than those calculated in frontal exposure, where the EAS-body distance is shorter. Nevertheless, in all studied cases, with an EAS driving current of 4 A rms, maximum induced current and SAR values are below basic restrictions.

Spontaneous and persistent currents in superconductive and mesoscopic structures (Review Article)

International Nuclear Information System (INIS)

Kulik, I.O.

2004-01-01

We briefly review aspects of superconductive persistent currents in Josephson junctions of the S/I/S, S/O/S and S/N/S types, focusing on the origin of jumps in the current versus phase dependences, and discuss in more detail the persistent as well as 'spontaneous' currents in the Aharonov-Bohm mesoscopic and nanoscopic (macromolecular) structures. A fixed-number-of-electrons mesoscopic or macromolecular conducting ring is shown to be unstable against structural transformation removing spatial symmetry (in particular, azimuthal periodicity) of its electron- lattice Hamiltonian. In case when the transformation is blocked by strong coupling to an external azimuthally symmetric environment, the system becomes bistable in its electronic configuration at certain number of electrons. At such a condition, the persistent current has a nonzero value even at the (almost) zero applied Aharonov-Bohm flux, and results in very high magnetic susceptibility dM/dH at small nonzero fields, followed by an oscillatory dependence at larger fields. We tentatively assume that previously observed oscillatory magnetization in cyclic metallo-organic molecules by Gatteschi et al. can be attributed to persistent currents. If this proves correct, it may open an opportunity (and, more generally, macromolecular cyclic structures may suggest the possibility) of engineering quantum computational tools based on the Aharonov-Bohm effect in ballistic nanostructures and macromolecular cyclic aggregates

2011-02-01

The goal of the present study was to evaluate the publication rate of abstracts presented during the German Anesthesia Congress (Deutscher Anästhesiecongress, DAC) and the meeting of the European Society of Anesthesiologists (ESA) in the years 2000 and 2005 in Medline listed journals (http://www.ncbi.nlm.nih.gov/pubmed). In addition, the respective impact factors of the journals in which the articles were published were evaluated (http://www.isiknowledge.com). All abstracts of free papers and posters presented at the DAC and ESA from the years 2000 and 2005 were included into the study. The presence of authors and the topics of abstracts in the literature were analyzed by a Medline based inquiry over a time period of 5 years. The search was based on the last name and initials of authors and when these could not be identified in Medline the search was extended by keywords of relevant topics of the abstract. Umlauts "ä/ö/ü" were replaced by "ae/oe/ue" and "ß" was replaced by "ss". Only original papers were included in this analysis. Once an original paper was found the impact factor of the journal in that year was identified. A total of 465 abstracts from the DAC 2000, 378 abstracts from the DAC 2005, 644 abstracts from the ESA 2000 and 720 abstracts from the ESA 2005 were included. Of the abstracts from the DAC 2000, 183 (39%) were published in Medline listed journals, 179 (47%) from DAC 2005, 218 (34%) from ESA 2000 and 233 (32%) from ESA 2005. The ESA abstracts were published in English more often than the DAC abstracts (ESA 2000: 95%; ESA 2005: 95%; DAC 2000: 78%; DAC 2005: 86%). While the publication rate after the ESA remained nearly unchanged between 2000 and 2005, the publication rate after the DAC increased by about 7%. The average impact factors of the publications were 1.777 (DAC 2000), 2.836 (DAC 2005), 1.825 (ESA 2000) and 2.36 (ESA 2005). Independent of the congress (DAC or ESA) where the abstract was presented, most articles were published in the

By regulation of the ratio of boron carbide particles to diluent particles, normally within the range of 1:9 and 9:1 and preferably within the range of 1:5 to 5:1, the neutron absorbing activity of the product may be controlled, which facilitates the manufacture of articles of particular absorbing activities best suitable for specific applications

Current collective engagement stakeholder strategies for South African labour relations

Directory of Open Access Journals (Sweden)

Popi C. Madlala

2018-05-01

Full Text Available Orientation: Collective engagement stakeholder strategies are significant for the creation of harmony in the workplace. It is a known fact that the South African (SA labour environment has been dominated by industrial action before and after the 1994 democratic transition. To be precise, the statistics reveals that industrial action has increased and become more destructive post-1994. Purpose: The purpose of this article was to present the current collective engagement stakeholder strategies for South African labour relations. Motivation for the study: The SA mining sector has seen more violent strikes, with a higher number of deaths, injuries, criminal activities, arrests, dismissals and job losses in recent years. This article captures the current mining stakeholder strategies shaping the existing labour relations environment. Research approach, design and method: This is a theoretical article highlighting the recent literature on collective engagement in the mining sector in South Africa. Main findings: This article presents the current labour relations incidents, reflecting the need for more effective collective engagement and stakeholder management strategies. Practical and managerial implications: The current labour relations context has prompted key stakeholders at the National Economic Development and Labour Council (NEDLAC to look specifically at promoting employment, labour market stability, the right to strike, minimising violence through collective bargaining and highlighting the role of the state, reducing vulnerability through social protection and increasing the minimum wage. Contribution or value add: This article adds theoretically to the existing body of knowledge regarding collective engagement and stakeholder strategies in the SA mining sector.

Full Text Available This short review article presents a current overview of existing publications and scientific results regarding liquid (ear acupuncture. The injection of liquids into defined acupuncture points of the ear is not a method commonly used in the Western world. The term liquid acupuncture has different definitions, which makes understanding each definition and differentiating one from the other difficult. General terms like pharmacopuncture, homeosiniatry, and liquid acupuncture, which all describe the method of injecting different kinds of drugs into a defined body acupuncture point, are used. This article presents the history of liquid acupuncture, as well as the current scientific state of the art, from the point of view of two European researchers. Some articles are discussed and a few practical examples are presented.

A CMC article and process for producing the article to have a layer on its surface that protects a reinforcement material within the article from damage. The method entails providing a body containing a ceramic reinforcement material in a matrix material that contains a precursor of a ceramic matrix material. A fraction of the reinforcement material is present and possibly exposed at a surface of the body. The body surface is then provided with a surface layer formed of a slurry containing a particulate material but lacking the reinforcement material of the body. The body and surface layer are heated to form the article by converting the precursor within the body to form the ceramic matrix material in which the reinforcement material is contained, and by converting the surface layer to form the protective layer that covers any fraction of the reinforcement material exposed at the body surface.

Review article: liver transplantation for hepatocellular carcinoma - a critical appraisal of the current worldwide listing criteria.

Menon, K V; Hakeem, A R; Heaton, N D

2014-10-01

Liver transplantation (LT) plays an important role in the management of patients with hepatocellular carcinoma (HCC). Although early results following LT for HCC were poor, since the introduction of the Milan criteria in 1996 morphological criteria have since been well established. Thereafter, various expansions of the Milan criteria were introduced worldwide. Listing criteria for LT for HCC in the United Kingdom (UK) initially conformed to the Milan criteria but were re-defined in 2009 by expansion of the Milan criteria. To look at the evidence in literature on listing criteria and management of HCC worldwide in comparison with the UK. Secondly, we aim to review worldwide vs. UK literature on prioritisation models, loco-regional therapy protocols and role of alpha-fetoprotein (AFP) in LT for HCC. An electronic literature search with Medline was carried out to identify articles related to LT for HCC. Although various expansions of the Milan criteria have been described, they remain the gold standard against which other criteria are measured. The UK criteria are an expansion of the Milan criteria that go beyond Milan and University of California, San Francisco (UCSF) criteria. The current UK listing criteria for LT for HCC when compared to the worldwide criteria have a worse survival benefit (projected 5-year survival between 35-50%) when plotted on the metroticket calculator. In keeping with most transplant centres worldwide, the UK have adopted expansions to Milan to allow more patients to benefit from LT. However, currently, as it stands the UK criteria when plotted in the modification of the Metroticket model project worse survival that would seem unjustified. © 2014 John Wiley & Sons Ltd.

Pronouns as Means of Impersonal Presentation in English Quality Press

Directory of Open Access Journals (Sweden)

Pavel Skorupa

2017-05-01

Full Text Available The current paper presents the analysis of pronouns as means of impersonal presentation in English quality press. The article gives the definition of the pronoun as a grammatical category and describes the use and purpose of impersonalization strategies. The data for the investigation was taken from the international English quality newspapers: The Financial Times (UK and The Wall Street Journal (US, which are the leading daily broadsheet newspapers in the UK and the USA having millions of both print and online subscribers worldwide. The articles on political, economic, and social issues were chosen on a random basis and scrutinized for pronouns as means of impersonal presentation of fact. The body of 187 cases of impersonalization chosen for the analysis were divided into groups with focus on the grammatical category they belong to. The most and least often used classes of pronouns were identified and compared. The results of the current study may be useful for editors, journalists, writers, as well as for further study of impersonalization strategies in the English language.

Graphical Presentation of Patient-Treatment Interaction Elucidated by Continuous Biomarkers. Current Practice and Scope for Improvement.

Science.gov (United States)

Shen, Yu-Ming; Le, Lien D; Wilson, Rory; Mansmann, Ulrich

2017-01-09

Biomarkers providing evidence for patient-treatment interaction are key in the development and practice of personalized medicine. Knowledge that a patient with a specific feature - as demonstrated through a biomarker - would have an advantage under a given treatment vs. a competing treatment can aid immensely in medical decision-making. Statistical strategies to establish evidence of continuous biomarkers are complex and their formal results are thus not easy to communicate. Good graphical representations would help to translate such findings for use in the clinical community. Although general guidelines on how to present figures in clinical reports are available, there remains little guidance for figures elucidating the role of continuous biomarkers in patient-treatment interaction (CBPTI). To combat the current lack of comprehensive reviews or adequate guides on graphical presentation within this topic, our study proposes presentation principles for CBPTI plots. In order to understand current practice, we review the development of CBPTI methodology and how CBPTI plots are currently used in clinical research. The quality of a CBPTI plot is determined by how well the presentation provides key information for clinical decision-making. Several criteria for a good CBPTI plot are proposed, including general principles of visual display, use of units presenting absolute outcome measures, appropriate quantification of statistical uncertainty, correct display of benchmarks, and informative content for answering clinical questions especially on the quantitative advantage for an individual patient with regard to a specific treatment. We examined the development of CBPTI methodology from the years 2000 - 2014, and reviewed how CBPTI plots were currently used in clinical research in six major clinical journals from 2013 - 2014 using the principle of theoretical saturation. Each CBPTI plot found was assessed for appropriateness of its presentation and clinical utility

Full Text Available This study sought to investigate whether there is any effect of the traditional grammar teaching on Standard Six learners’ performance in understanding and using simple present tense, simple past tense, pronouns and articles in writing. The sample for the study consisted of 40 Standard Six students of SK Tansau, Putatan, Kota Kinabalu, Sabah who was divided equally into two groups which were the treatment group and the control groups. Tests of understanding and of using the simple present tense, simple past tense, pronouns and articles were used as the instruments of the study. The data was collected through the administration of the pre-test and post-test. To analyze the collected data, the SPSS (Statistical Packages for Social Sciences version 11.5 was used. T-test was used to see if there was a significant difference in the mean of gain score. The Pearson Correlation was used on both tests between treatment group and control group to establish the relationship between scores on understanding and scores on using the grammatical features investigated. The study found that there was no significant difference in the mean of gain score in simple present tense, simple past tense and pronouns of the understanding test as well as writing test between the treatment and control groups. The results also indicated that there was no correlation between scores on test of understanding and test of using simple present tense, simple past tense, pronouns and articles on writing in the treatment group. There have been research studies in the past that lend clear cut support to the teaching of grammar as a mean of improving writing, however the results of this research clearly show that the implementation of Traditional Grammar Teaching has no effects on the students’ writing.

A neutron absorbing article, preferably in long, thin, flat form , suitable for but not necessarily limited to use in storage racks for spent nuclear fuel at locations between volumes of such stored fuel, to absorb neutrons from said spent fuel and prevent uncontrolled nuclear reaction of the spent fuel material, is composed of finely divided boron carbide particles and a solid, irreversibly cured phenolic polymer, forming a continuous matrix about the boron carbide particles, in such proportions that at least 6% of b10 from the boron carbide content is present therein. The described articles withstand thermal cycling from repeated spent fuel insertions and removals, withstand radiation from said spent nuclear fuel over long periods of time without losing desirable neutron absorbing and physical properties, are sufficiently chemically inert to water so as to retain neutron absorbing properties if brought into contact with it, are not galvanically corrodible and are sufficiently flexible so as to withstand operational basis earthquake and safe shutdown earthquake seismic events, without loss of neutron absorbing capability and other desirable properties, when installed in storage racks for spent nuclear fuel. The disclosure also relates to a plurality of such neutron absorbing articles in a storage rack for spent nuclear fuel and to a method for the manufacture of the articles

Electric Currents along Astrophysical Jets

Directory of Open Access Journals (Sweden)

Ioannis Contopoulos

2017-10-01

Full Text Available Astrophysical black holes and their surrounding accretion disks are believed to be threaded by grand design helical magnetic fields. There is strong theoretical evidence that the main driver of their winds and jets is the Lorentz force generated by these fields and their associated electric currents. Several researchers have reported direct evidence for large scale electric currents along astrophysical jets. Quite unexpectedly, their directions are not random as would have been the case if the magnetic field were generated by a magnetohydrodynamic dynamo. Instead, in all kpc-scale detections, the inferred electric currents are found to flow away from the galactic nucleus. This unexpected break of symmetry suggests that a battery mechanism is operating around the central black hole. In the present article, we summarize observational evidence for the existence of large scale electric currents and their associated grand design helical magnetic fields in kpc-scale astrophysical jets. We also present recent results of general relativistic radiation magnetohydrodynamic simulations which show the action of the Cosmic Battery in the vicinity of astrophysical black holes.

Basically, they give world leading physicists the opportunity to write what they think about the key issues in their field, free from the usual requirement to provide the fair and balanced presentations of the subject normally found in articles in Reports on Progress in Physics. We believe that the readers of the journal will be interested to learn about these exciting ideas. Just as Hilbert's famous paper of 1900 set the agenda for the next century or more in mathematics, so we hope that this series of papers will define the key issues and open questions in physics for the 21st Century and that the articles will be widely cited and downloaded. The first of these articles—'Insights from simulations of star formation' by Richard B Larson (Yale University, USA)—is published in the current issue. We trust that readers will find this article and its successors in the series to appear through 2007 and beyond entertaining and stimulating.

Advanced electrical current measurements of microdischarges: evidence of sub-critical pulses and ion currents in barrier discharge in air

Science.gov (United States)

Synek, Petr; Zemánek, Miroslav; Kudrle, Vít; Hoder, Tomáš

2018-04-01

Electrical current measurements in corona or barrier microdischarges are a challenge as they require both high temporal resolution and a large dynamic range of the current probe used. In this article, we apply a simple self-assembled current probe and compare it to commercial ones. An analysis in the time and frequency domain is carried out. Moreover, an improved methodology is presented, enabling both temporal resolution in sub-nanosecond times and current sensitivity in the order of tens of micro-amperes. Combining this methodology with a high-tech oscilloscope and self-developed software, a unique statistical analysis of currents in volume barrier discharge driven in atmospheric-pressure air is made for over 80 consecutive periods of a 15 kHz applied voltage. We reveal the presence of repetitive sub-critical current pulses and conclude that these can be identified with the discharging of surface charge microdomains. Moreover, extremely low, long-lasting microsecond currents were detected which are caused by ion flow, and are analysed in detail. The statistical behaviour presented gives deeper insight into the discharge physics of these usually undetectable current signals.

An On-Site Presentation of Invisible Prehistoric Landscapes

Directory of Open Access Journals (Sweden)

Jiri Unger

2017-03-01

Full Text Available The rapid development of information technology has enabled the creation of entirely new presentation frameworks and this article will attempt to explore the subject of on-site presentation of archaeological sites. The most frequently used environment currently has been in the form of a variety of virtual museums that are accessible on the Internet; in essence these keep their visitors stuck in front of a PC monitor. One option that allows leaving the monitor and stepping directly out-of-doors into a virtual open-air museum is by means of applications for mobile phones. Terms such as 'virtual' or 'augmented reality' no longer represent a million light-years away science-fiction concepts, but rather a new tool for public archaeology and for the preservation of the archaeological heritage. This article presents several projects that have been implemented by the Archaeological Institute in Prague, who, by using mobile applications, built virtual open-air museums directly in the locations of archaeological excavations.

To analyze the publication rates of full-text journal articles converted from the abstracts presented in the 22(nd) Turkish National Urology Congress in 2012. A total of 576 abstracts accepted for presentation at the 22(nd) Turkish National Urology Association Meeting were identified from the published abstract book. The abstracts were categorized into subsections such as endourology and pediatric urology. The subsequent publication rate for the studies was evaluated by scanning PubMed Medline. Abstracts published before the proceedings were excluded from the study. The abstracts were categorized as being presented orally (n=155), by poster (n=421), or by video (n=78). Of the 28 (18.3%) of 155 oral and 34 (8.15%) of 421 poster presentations, were subsequently published in several journals until March 2015. The publication rates of the abstracts based on urology subsections were as follows: neurology (25%), andrology (18.6%), endourology (17.2%), urolithiasis (15.3%), general urology (12.5%), infectious diseases (7.14%), pediatric urology (6.25%), uro-gynecology (6.06%), reconstructive urology (5.8%), and urooncology (3.8%). The average time to publication was 11.77 (0-33) months. This is the first study assessing the publication rates of abstracts presented at a Turkish National Urology Congress. It reveals that more qualified randomized studies need to be done to improve the rate of publication.

WAIS Searching of the Current Contents Database

Science.gov (United States)

Banholzer, P.; Grabenstein, M. E.

The Homer E. Newell Memorial Library of NASA's Goddard Space Flight Center is developing capabilities to permit Goddard personnel to access electronic resources of the Library via the Internet. The Library's support services contractor, Maxima Corporation, and their subcontractor, SANAD Support Technologies have recently developed a World Wide Web Home Page (http://www-library.gsfc.nasa.gov) to provide the primary means of access. The first searchable database to be made available through the HomePage to Goddard employees is Current Contents, from the Institute for Scientific Information (ISI). The initial implementation includes coverage of articles from the last few months of 1992 to present. These records are augmented with abstracts and references, and often are more robust than equivalent records in bibliographic databases that currently serve the astronomical community. Maxima/SANAD selected Wais Incorporated's WAIS product with which to build the interface to Current Contents. This system allows access from Macintosh, IBM PC, and Unix hosts, which is an important feature for Goddard's multiplatform environment. The forms interface is structured to allow both fielded (author, article title, journal name, id number, keyword, subject term, and citation) and unfielded WAIS searches. The system allows a user to: Retrieve individual journal article records. Retrieve Table of Contents of specific issues of journals. Connect to articles with similar subject terms or keywords. Connect to other issues of the same journal in the same year. Browse journal issues from an alphabetical list of indexed journal names.

Direct current induced short-term modulation of the left dorsolateral prefrontal cortex while learning auditory presented nouns

Directory of Open Access Journals (Sweden)

Meyer Martin

2009-07-01

Full Text Available Abstract Background Little is known about the contribution of transcranial direct current stimulation (tDCS to the exploration of memory functions. The aim of the present study was to examine the behavioural effects of right or left-hemisphere frontal direct current delivery while committing to memory auditory presented nouns on short-term learning and subsequent long-term retrieval. Methods Twenty subjects, divided into two groups, performed an episodic verbal memory task during anodal, cathodal and sham current application on the right or left dorsolateral prefrontal cortex (DLPFC. Results Our results imply that only cathodal tDCS elicits behavioural effects on verbal memory performance. In particular, left-sided application of cathodal tDCS impaired short-term verbal learning when compared to the baseline. We did not observe tDCS effects on long-term retrieval. Conclusion Our results imply that the left DLPFC is a crucial area involved in short-term verbal learning mechanisms. However, we found further support that direct current delivery with an intensity of 1.5 mA to the DLPFC during short-term learning does not disrupt longer lasting consolidation processes that are mainly known to be related to mesial temporal lobe areas. In the present study, we have shown that the tDCS technique has the potential to modulate short-term verbal learning mechanism.

100 articles every ecologist should read.

Science.gov (United States)

Courchamp, Franck; Bradshaw, Corey J A

2018-02-01

Reading scientific articles is a valuable and major part of the activity of scientists. Yet, with the upsurge of currently available articles and the increasing specialization of scientists, it becomes difficult to identify, let alone read, important papers covering topics not directly related to one's own specific field of research, or that are older than a few years. Our objective was to propose a list of seminal papers deemed to be of major importance in ecology, thus providing a general 'must-read' list for any new ecologist, regardless of particular topic or expertise. We generated a list of 544 papers proposed by 147 ecology experts (journal editorial members) and subsequently ranked via random-sample voting by 368 of 665 contacted ecology experts, covering 6 article types, 6 approaches and 17 fields. Most of the recommended papers were not published in the highest-ranking journals, nor did they have the highest number of mean annual citations. The articles proposed through the collective recommendation of several hundred experienced researchers probably do not represent an 'ultimate', invariant list, but they certainly contain many high-quality articles that are undoubtedly worth reading-regardless of the specific field of interest in ecology-to foster the understanding, knowledge and inspiration of early-career scientists.

Teleradiology - current status

International Nuclear Information System (INIS)

Baltadjiev, D.; Charakchiev

2000-01-01

Tele-radiology is a term becoming increasingly popular in the medical literature. Nevertheless, terminological definitions in this particular field are still rather vague. The scope of applications extend from simple image presenting via analogue telephone lines to transmission of 3-D medical images through a satellite. It is a matter of standards highly differing in terms of data transmission rates, safety, technical demands on the systems and the like. In this article new information technologies, technical aspects, as well as some major applications of tele-radiology are discussed. The current status of tele-medicine/tele-radiology in this country is likewise briefly outlined

Predicting the importance of current papers.

Energy Technology Data Exchange (ETDEWEB)

Klavans, Richard (SciTech Strategies, Inc., Berwyn, PA); Boyack, Kevin W.

2005-01-01

This article examines how well one can predict the importance of a current paper (a paper that is recently published in the literature). We look at three factors--journal importance, reference importance and author reputation. Citation-based measures of importance are used for all variables. We find that journal importance is the best predictor (explaining 22.3% out of a potential 29.1% of the variance in the data), and that this correlation value varies significantly by discipline. Journal importance is a better predictor of citation in Computer Science than in any other discipline. While the finding supports the present policy of using journal impact statistics as a surrogate for the importance of current papers, it calls into question the present policy of equally weighting current documents in text-based analyses. We suggest that future researchers take into account the expected importance of a document when attempting to describe the cognitive structure of a field.

Eddy current is a very important NDT inspection method widely used to perform integrity evaluation of tubes installed in heat exchangers. For nuclear power plants, a classical example is the remote inspection of steam generators and condensers, as well as other ordinary auxiliary equipment. Data evaluation can be performed by means of precise phase and amplitude measurements of complex impedance signals, represented as Lissajous figures plotted on the screen of the inspection systems. This paper presents the software EASY, a computer assisted analysis system developed at CDTN to help the characterization of volumetric discontinuities present in heat exchangers tubes. Data to be analyzed are obtained from commercial eddy current equipment data file, such as ECT MAD8D. Main advantage of that system is its portability and easy use, since it can be executed in ordinary PC, under Microsoft Windows operating system. (author)

Bejan, A.; Cluss, E.M. Jr.

1976-01-01

Superconducting magnets are energized through helium vapour-cooled cryogenic current leads operating at high ratios of current to mass flow. The high current operation where lead temperature, runaway, and eventual burn-up are likely to occur is investigated. A simple criterion for estimating the burn-up operation conditions (current, mass flow) for a given lead geometry (cross-sectional area, length, heat exchanger area) is presented. This article stresses the role played by the available heat exchanger area in avoiding burn-up at high ratios of current to mass flow. (author)

Research projects are presented at the Annual Meetings of the American Society for Surgery of the Hand (ASSH). It is unknown how many achieve publication in peer-reviewed journals. We sought to determine current rates of publication of podium and poster presentations. All ASSH podium and poster presentations from 2000 to 2005 were reviewed, and an Internet-based search using PubMed and Google was conducted to determine whether the presented studies had been published. Times to publication and journal names were recorded. Data were analyzed with descriptive statistics. Fisher's exact test was conducted to compare current trends with previous trends. Of 1127 podium and poster presentations reviewed, 46% were published in peer-reviewed journals. Forty-seven percent of published presentations (242 presentations) were in Journal of Hand Surgery, and 11% (59 presentations) were in Journal of Bone and Joint Surgery. Forty-five percent of presentations were published within 2 years and 66% within 3 years. The publication rate for podium presentations was significantly higher than that previously reported for Journal of Hand Surgery, at 54% compared with 44% (P=0.004). Currently, fewer than half of the studies presented at Annual Meetings of the ASSH achieve publication in peer-reviewed journals. Presentations are most likely to be published within 3 years, and almost half are published in Journal of Hand Surgery.

Questioning the efficacy of 'gold' open access to published articles.

Science.gov (United States)

Fredericks, Suzanne

2015-07-01

To question the efficacy of 'gold' open access to published articles. Open access is unrestricted access to academic, theoretical and research literature that is scholarly and peer-reviewed. Two models of open access exist: 'gold' and 'green'. Gold open access provides everyone with access to articles during all stages of publication, with processing charges paid by the author(s). Green open access involves placing an already published article into a repository to provide unrestricted access, with processing charges incurred by the publisher. This is a discussion paper. An exploration of the relative benefits and drawbacks of the 'gold' and 'green' open access systems. Green open access is a more economic and efficient means of granting open access to scholarly literature but a large number of researchers select gold open access journals as their first choices for manuscript submissions. This paper questions the efficacy of gold open access models and presents an examination of green open access models to encourage nurse researchers to consider this approach. In the current academic environment, with increased pressures to publish and low funding success rates, it is difficult to understand why gold open access still exists. Green open access enhances the visibility of an academic's work, as increased downloads of articles tend to lead to increased citations. Green open access is the cheaper option, as well as the most beneficial choice, for universities that want to provide unrestricted access to all literature at minimal risk.

2011-08-01

Full Text Available Abstract Many studies are currently investigating the development of safe and effective vaccines to prevent various infectious diseases. Multiple antigen-presenting peptide vaccine systems have been developed to avoid the adverse effects associated with conventional vaccines (i.e., live-attenuated, killed or inactivated pathogens, carrier proteins and cytotoxic adjuvants. Recently, two main approaches have been used to develop multiple antigen-presenting peptide vaccine systems: (1 the addition of functional components, e.g., T-cell epitopes, cell-penetrating peptides, and lipophilic moieties; and (2 synthetic approaches using size-defined nanomaterials, e.g., self-assembling peptides, non-peptidic dendrimers, and gold nanoparticles, as antigen-displaying platforms. This review summarizes the recent experimental studies directed to the development of multiple antigen-presenting peptide vaccine systems.

Statistical methods play an important role in medical and dental research. In earlier studies it has been observed that current use of methods and reporting of statistics are responsible for some of the errors in the interpretation of results. The aim of this study was to investigate the quality of statistical reporting in dental research articles. A total of 200 articles published in 2010 were analysed covering five dental journals: Journal of Dental Research, Caries Research, Community Dentistry and Oral Epidemiology, Journal of Dentistry and Acta Odontologica Scandinavica. Each paper underwent careful scrutiny for the use of statistical methods and reporting. A paper with at least one poor reporting item has been classified as 'problems with reporting statistics' and a paper without any poor reporting item as 'acceptable'. The investigation showed that 18 (9%) papers were acceptable and 182 (91%) papers contained at least one poor reporting item. The proportion of at least one poor reporting item in this survey was high (91%). The authors of dental journals should be encouraged to improve the statistical section of their research articles and to present the results in such a way that it is in line with the policy and presentation of the leading dental journals.

What's known on the subject? and What does the study add? It is well known that the transition of a presented abstract in a scientific meeting to a journal article improves the quality of the meeting and prevents an abstract being incorporated into meta-analyses or practice guidelines without proper appraisal. This is the first analysis of USANZ Annual Scientific Meeting abstracts' conversion to full publication. With relatively low publication rates compared to other international meetings, this review identifies the need for mechanisms to encourage USANZ researchers to convert their abstracts into published articles. The numbers and characteristics of the abstracts presented at the Annual Scientific Meetings (ASM) of the Urological Society of Australia and New Zealand (USANZ) that are converted to peer-reviewed publications have not previously been analysed and published. We undertook a review of all abstracts presented at the USANZ ASM from 2005 to 2009. A PubMed search was performed between 15 June and 15 July 2012, using a search algorithm to identify the full-text publications of the presented abstracts. Correlation between abstract characteristics and publication rate was then examined to distinguish the predictors for publications. Of 614 abstracts that were presented at USANZ ASM between 2005 and 2009, 183 papers were published, giving a publication rate of 29.80%. The papers were predominantly published in urological journals and were more likely to be published if they were presented by an international author or were retrospective studies or if basic science research. The mean (SD) time to publication was 14.46 (13.89) months and the mean Impact Factor of journals where papers were published was 2.90. The overall publication rate was relatively low compared with other urological meetings held in America and Europe. USANZ has a challenge of encouraging higher-quality research from the authors to further enhance its publication rate and consequently the

A correctly drafted original article gives information on what was done, why it was done, how it was done, the result of what was done, and the significance of what was done. Many articles fail to report their results effectively. To describe the characteristics of an original article and to give practical recommendations to prevent the most common errors in our environment. We performed a systematic search of the terms "how to write a scientific article", "structure of the original article" and "publishing an article" in the databases PubMed and SCOPUS. We analysed the structure of an original article and the characteristics of its parts and prepared advice on the publication of an article. The journal's guidelines for authors should be read. It is usual for the original article to follow the IMRAD structure: Introduction, Methods, Results and Discussion. The introduction states briefly why the study was performed. The methods' section should give a detailed explanation of how the study was performed. The results should be clearly presented, with the help of tables, without repeating information. The discussion explains the relevance of the results and contrasts them with those of other authors. Any limitations and a conclusion supported by the results must be included. Writing an original article correctly requires practice and it must be supported by a good research work in order to be published. Copyright © 2018 AEU. Publicado por Elsevier España, S.L.U.

2014-09-01

Full Text Available Background:  Research projects are presented at the Annual Meetings of the American Society for Surgery of the Hand (ASSH. It is unknown how many achieve publication in peer-reviewed journals. We sought to determine current rates of publication of podium and poster presentations.   Methods:  All ASSH podium and poster presentations from 2000 to 2005 were reviewed, and an Internet-based search using PubMed and Google was conducted to determine whether the presented studies had been published. Times to publication and journal names were recorded. Data were analyzed with descriptive statistics. Fisher’s exact test was conducted to compare current trends with previous trends. Results:  Of 1127 podium and poster presentations reviewed, 46% were published in peer-reviewed journals. Forty-seven percent of published presentations (242 presentations were in Journal of Hand Surgery , and 11% (59 entations were in Journal of Bone and Joint Surgery . Forty-five percent of presentations were published within 2 years and 66% within 3 years. The publication rate for podium presentations was significantly higher than that previously reported for Journal of Hand Surgery, at 54% compared with 44% (P=0.004.  Conclusions:  Currently, fewer than half of the studies presented at Annual Meetings of the ASSH achieve publication in peer-eviewed journals. Presentations are most likely to be published within 3 years, and almost half are published in Journal of Hand Surgery .

Wang, Ching-Min; Chen, Shou-Chien; Chen, Kow-Tong

2015-11-01

Rotaviruses remain the major cause of childhood diarrheal disease worldwide and of diarrheal deaths of infants and children in developing countries. The huge burden of childhood rotavirus-related diarrhea in the world continues to drive the remarkable pace of vaccine development. Research articles were searched using terms "rotavirus" and "rotavirus vaccine" in MEDLINE and PubMed. Articles not published in the English language, articles without abstracts, and opinion articles were excluded from the review. After preliminary screening, all articles were reviewed and synthesized to provide an overview of current vaccines and vaccination programs. In this review of the global rotavirus vaccines and vaccination programs, the principles of rotavirus vaccine development and the efficacy of the currently licensed vaccines from both developed and developing countries were summarized. Rotavirus is a common cause of diarrhea in children in both developed and developing countries. Rotavirus vaccination is a cost-effective measure to prevent rotavirus diarrhea.

Clinical linguistics: its past, present and future.

Science.gov (United States)

Perkins, Michael R

2011-11-01

Historiography is a growing area of research within the discipline of linguistics, but so far the subfield of clinical linguistics has received virtually no systematic attention. This article attempts to rectify this by tracing the development of the discipline from its pre-scientific days up to the present time. As part of this, I include the results of a survey of articles published in Clinical Linguistics & Phonetics between 1987 and 2008 which shows, for example, a consistent primary focus on phonetics and phonology at the expense of grammar, semantics and pragmatics. I also trace the gradual broadening of the discipline from its roots in structural linguistics to its current reciprocal relationship with speech and language pathology and a range of other academic disciplines. Finally, I consider the scope of clinical linguistic research in 2011 and assess how the discipline seems likely develop in the future.

A systematic review of Bayesian articles in psychology: The last 25 years.

Science.gov (United States)

van de Schoot, Rens; Winter, Sonja D; Ryan, Oisín; Zondervan-Zwijnenburg, Mariëlle; Depaoli, Sarah

2017-06-01

Although the statistical tools most often used by researchers in the field of psychology over the last 25 years are based on frequentist statistics, it is often claimed that the alternative Bayesian approach to statistics is gaining in popularity. In the current article, we investigated this claim by performing the very first systematic review of Bayesian psychological articles published between 1990 and 2015 (n = 1,579). We aim to provide a thorough presentation of the role Bayesian statistics plays in psychology. This historical assessment allows us to identify trends and see how Bayesian methods have been integrated into psychological research in the context of different statistical frameworks (e.g., hypothesis testing, cognitive models, IRT, SEM, etc.). We also describe take-home messages and provide "big-picture" recommendations to the field as Bayesian statistics becomes more popular. Our review indicated that Bayesian statistics is used in a variety of contexts across subfields of psychology and related disciplines. There are many different reasons why one might choose to use Bayes (e.g., the use of priors, estimating otherwise intractable models, modeling uncertainty, etc.). We found in this review that the use of Bayes has increased and broadened in the sense that this methodology can be used in a flexible manner to tackle many different forms of questions. We hope this presentation opens the door for a larger discussion regarding the current state of Bayesian statistics, as well as future trends.

How to respond to referee comments for scientific articles?

Science.gov (United States)

Kalemci, Mustafa Serdar; Turna, Burak

2013-09-01

Currently, the increasing number of article submissions to scientific journals forces editors to be more selective in their acceptance of papers. Consequently, editors have increased the frequency of their use of scientific referee mechanisms. For many researchers, the publication of a scientific article in a high impact factor journal is a gradual and difficult process. After preparation and submission of a manuscript, one of the most important issue is responding to the comments of referees. However, there is a paucity of published reports in the literature describing how to respond to these comments. The aim of this review is to assist researchers/authors in responding to referee comments as part of the publication process for scientific articles.

Low-Frequency Pulsed Current Versus Kilohertz-Frequency Alternating Current: A Scoping Literature Review.

Science.gov (United States)

Vaz, Marco Aurélio; Frasson, Viviane Bortoluzzi

2018-04-01

To compare the effectiveness of low-frequency pulsed current versus kilohertz-frequency alternating current in terms of evoked force, discomfort level, current intensity, and muscle fatigability; to discuss the physiological mechanisms of each neuromuscular electrical stimulation type; and to determine if kilohertz-frequency alternating current is better than low-frequency pulsed current for clinical treatment. Articles were obtained from PubMed, Scopus, Cochrane Central Register of Controlled Trials, CINAHL, MEDLINE, and SPORTSDiscus databases using the terms Russian current or kilohertz current or alternating current or pulsed current or Aussie current and torque or discomfort or fatigue or current intensity, and through citation tracking up to July 2017. Two independent reviewers selected studies comparing the use of the 2 neuromuscular electrical stimulation currents. Studies describing maximal current intensity tolerated and the main effects of the 2 different current types on discomfort, muscle force, and fatigability were independently reviewed. Data were systematized according to (1) methodology; (2) electrical current characteristics; and (3) outcomes on discomfort level, evoked force, current intensity, and muscle fatigability. The search revealed 15 articles comparing the 2 current types. Kilohertz-frequency alternated current generated equal or less force, similar discomfort, similar current intensity for maximal tolerated neuromuscular electrical stimulation, and more fatigue compared with low-frequency pulsed current. Similar submaximal levels of evoked force revealed higher discomfort and current intensity for kilohertz-frequency alternated current compared with low-frequency pulsed current. Available evidence does not support the idea that kilohertz-frequency alternated current is better than low-frequency pulsed current for strength training and rehabilitation.

Theile, Cheryl Westphal

2017-09-01

The state of the dental hygiene educational system in the United States is evolving. The numbers of programs, extent of curricula, and diversity of students, faculty, and practice settings vary significantly across the country. New trends in workforce utilization and delivery models are challenging current educational foundations and mandating an interprofessional approach to both the education and practice of dental hygienists. This article presents an overview of the current state of dental hygiene education to create a baseline for discussion of desired educational models for 2040. The strengths and weaknesses are defined to motivate change. Limitations of the current two-year associate degree are emphasized, along with the need to add expanded content and development of new skills. The developing non-traditional practice settings bring both a challenge to dental hygiene education and a promise of increasing potential in primary care interprofessional settings for the 21 st century. This article was written as part of the project "Advancing Dental Education in the 21 st Century."

Full Text Available Free-living amoebae belonging to the genus Acanthamoeba have an environmental distribution. Amoebic keratitis due to these protozoan parasites continue to rise in Iran and worldwide. In Iran, there are various researches regarding both morphological and molecular identification of Acanthamoeba spp. in environmental and clinical samples. However, there is no thorough review about Acanthamoeba genotypes and their distribution in environmental sources such as water, dust and biofilm in Iran. Besides, according to increasing cases of Amoebic keratitis in the region awareness regarding the pathogenic potential of these sight-threatening amoebae is of utmost importance.We conducted a thorough review based on the database sources such as MEDLINE, PubMed and Google scholar. No restrictions were placed on study date, study design or language of publication. We searched all valuable and relevant information considering the occurrence of the Acanthamoeba in both environmental and clinical samples.According to our thorough review Acanthamoeba belonging to T4 genotype is the most prevalent type strain in environmental and clinical samples in several regions in Iran and worldwide, however, there are reports regarding Acanthamoeba belonging to other genotypes such as T2, T3, T5, T6 and T11 and the mentioned point could leads us to more researches with the goal of presenting the real genotype dominance of Acanthamoeba and related disease in the country.Overall, the present review will focus on present status of genotypes of Acanthamoeba in Iran during recent years.

Tissue adhesives are gaining popularity in ophthalmology, as they could potentially reduce the complications associated with current surgical methods. An ideal tissue adhesive should have superior tensile strength, be non-toxic and anti-inflammatory, improve efficiency and be cost-effective. Both synthetic and biological glues are available. The primary synthetic glues include cyanoacrylate and the recently introduced polyethylene glycol (PEG) derivatives, while most biological glues are composed of fibrin. Cyanoacrylate has a high tensile strength, but rapidly polymerises upon contact with any fluid and has been associated with histotoxicity. Fibrin induces less toxic and inflammatory reactions, and its polymerisation time can be controlled. Tensile strength studies have shown that fibrin is not as strong as cyanoacrylate. While more research is needed, PEG variants currently appear to have the most promise. These glues are non-toxic, strong and time-effective. Through MEDLINE and internet searches, this paper presents a systematic review of the current applications of surgical adhesives to corneal, glaucoma, retinal, cataract and strabismus surgeries. Our review suggests that surgical adhesives have promise to reduce problems in current ophthalmic surgical procedures. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Using ASM Podcasts to Excite Undergraduate Students about Current Microbiological Research

Directory of Open Access Journals (Sweden)

Stacey E. Lettini

2014-08-01

Full Text Available Innovative technology is often used as a mechanism to engage students in and out of the classroom and can be used to increase critical thinking skills. Podcasts are an excellent way to introduce students to current topics and research in microbiology. The American Society for Microbiology (ASM produces three podcasts that are microbiologically focused: This Week in Microbiology (TWiM, This Week in Parasitology (TWiP, and This Week in Virology (TWiV. These podcasts are usually presented in a manner similar to a journal club, as the presenters regularly invite guests to discuss current research papers. Since students often find reading scientific literature difficult and get bogged down in the details rather than seeing the over-arching purpose of a paper, these podcasts have been used in a General Microbiology course to introduce recent research articles. The students were first assigned an original research article to read and review, and they were asked to generate questions pertaining to things they did not understand. Next, students listened to the corresponding podcast that discussed the article and used it to answer their questions. This was followed by a classroom discussion of the article and the podcast. The ASM podcast helped to demystify original research by providing details of the experimental design and presentation of the results in a language that is more casual and relatable. Students demonstrated greater critical thinking and comprehension of microbiology literature after listening to the podcast. This activity can be used in a variety of courses in the biology curriculum.

A total of 46 journals were identified, and all articles published within these journals were analyzed for citation counts. The top 100 highly cited articles were recorded. The most frequently cited radiologic articles appeared in 9 of the 46 journals. These included 59 articles in Radiology, 17 in Journal of Nuclear Medicine, 9 in the American Journal of Roentgenology, 5 in the British Journal of Radiology, 4 in Investigative Radiology, 2 in American Journal of Neuroradiology, 2 in European Radiology, 2 in Radiologic Clinics of North America, 1 in the Seminars in Nuclear Medicine, and 1 in Pediatric Radiology. The citation values ranged from 422 to 7506 with a mean of 751. Publication dates ranged from 1967 to 2006 with the 5-year period between 1986 and 1990 accounting for the largest percentage of articles. The most frequently studied radiologic modality was magnetic resonance imaging (MRI; 28 articles), followed by vascular/interventional (19 articles) and nuclear medicine (13 articles). The central nervous system was the most frequently studied organ system (22 articles), followed by mixed organ systems (14 articles) and liver (12 articles). The top cited articles in radiologic journals span a wide range of imaging modalities, subspecialties, and organ systems. Topics that occurred frequently in the top 100 cited articles included contrast and radiopharmaceutical characterization, MRI of motion, percutaneous radiofrequency ablation in the liver and percutaneous vertebroplasty. We present a methodology that uses citation analysis to

The overall aim of the present study was to compare the coverage of existing research funding information for articles indexed in Scopus, Web of Science, and PubMed databases. The numbers of articles with funding information published in 2015 were identified in the three selected databases and compared using bibliometric analysis of a sample of twenty-eight prestigious medical journals. Frequency analysis of the number of articles with funding information showed statistically significant differences between Scopus, Web of Science, and PubMed databases. The largest proportion of articles with funding information was found in Web of Science (29.0%), followed by PubMed (14.6%) and Scopus (7.7%). The results show that coverage of funding information differs significantly among Scopus, Web of Science, and PubMed databases in a sample of the same medical journals. Moreover, we found that, currently, funding data in PubMed is more difficult to obtain and analyze compared with that in the other two databases.

Moxibustion, a form of traditional Chinese medicine (TCM), is the burning of the herb moxa (Folium Artemisiae argyi or mugwort) over acupuncture points. It is often used in China to facilitate cephalic version of breech presentation. This article reviews the history, philosophy, therapeutic use, possible mechanisms of action, and literature pertaining to its use for this indication. For moxibustion, moxa can be rolled into stick form, placed directly on the skin, or placed on an acupuncture needle and ignited to warm acupuncture points. Studies have demonstrated that moxibustion may promote cephalic version of breech presentation and may facilitate external cephalic version. However, there is currently a paucity of research on the effects of moxibustion on cephalic version of breech presentation, and thus there is a need for further studies. Areas needing more investigation include efficacy, safety, optimal technique, and best protocol for cephalic version of breech presentation. © 2018 by the American College of Nurse-Midwives.

Article retracted, but the message lives on.

Greitemeyer, Tobias

2014-04-01

The retraction of an original article aims to ensure that readers are alerted to the fact that the findings are not trustworthy. However, the present research suggests that individuals still believe in the findings of an article even though they were later told that the data were fabricated and that the article was retracted. Participants in a debriefing condition and a no-debriefing condition learned about the scientific finding of an empirical article, whereas participants in a control condition did not. Afterward, participants in the debriefing condition were told that the article had been retracted because of fabricated data. Results showed that participants in the debriefing condition were less likely to believe in the findings than participants in the no-debriefing condition but were more likely to believe in the findings than participants in the control condition, suggesting that individuals do adjust their beliefs in the perceived truth of a scientific finding after debriefing-but insufficiently. Mediational analyses revealed that the availability of generated causal arguments underlies belief perseverance. These results suggest that a retraction note of an empirical article in a scientific journal is not sufficient to ensure that readers of the original article no longer believe in the article's conclusions.

Finding and Recommending Scholarly Articles

Science.gov (United States)

Kurtz, Michael J.; Henneken, Edwin A.

2014-05-01

The rate at which scholarly literature is being produced has been increasing at approximately 3.5 percent per year for decades. This means that during a typical 40 year career the amount of new literature produced each year increases by a factor of four. The methods scholars use to discover relevant literature must change. Just like everybody else involved in information discovery, scholars are confronted with information overload. Two decades ago, this discovery process essentially consisted of paging through abstract books, talking to colleagues and librarians, and browsing journals. A time-consuming process, which could even be longer if material had to be shipped from elsewhere. Now much of this discovery process is mediated by online scholarly information systems. All these systems are relatively new, and all are still changing. They all share a common goal: to provide their users with access to the literature relevant to their specific needs. To achieve this each system responds to actions by the user by displaying articles which the system judges relevant to the user's current needs. Recently search systems which use particularly sophisticated methodologies to recommend a few specific papers to the user have been called "recommender systems". These methods are in line with the current use of the term "recommender system" in computer science. We do not adopt this definition, rather we view systems like these as components in a larger whole, which is presented by the scholarly information systems themselves. In what follows we view the recommender system as an aspect of the entire information system; one which combines the massive memory capacities of the machine with the cognitive abilities of the human user to achieve a human-machine synergy.

2010-01-01

Defined as reviews of clinical aspects of a specific health problem published in peer-reviewed and non-peer-reviewed medical journals, offered without charge, continuing medical education (CME) articles form a key strategy for translating knowledge into practice. This study assessed CME articles for mention of evidence-based information on benefits and harms of available treatment and/or preventive options that are deemed essential for shared decision making (SDM) to occur in clinical practice. Articles were selected from 5 medical journals that publish CME articles and are provided free of charge to primary-care physicians of the Province of Quebec, Canada. Two individuals independently scored each article with the use of a 10-item checklist based on the International Patient Decision Aid Standards. In case of discrepancy, the item score was established by team consensus. Scores were added to produce a total article score ranging from 0 (no item present) to 10 (all items present). Thirty articles (6 articles per journal) were selected. Total article scores ranged from 1 to 9, with a mean (+/- SD) of 3.1 +/- 2.0 (95% confidence interval 2.8-4.3). Health conditions and treatment options were the items most frequently discussed in the articles; next came treatment benefits. Possible harms, the use of the same denominators for benefits and harms, and methods to facilitate the communication of benefits and harms to patients were almost never described. No significant differences between journals were observed. The CME articles evaluated did not include the evidence-based information necessary to foster SDM in clinical practice. Peer-reviewed and non-peer-reviewed medical journals should require CME articles to include this type of information.

Current therapy for stable angina includes surgical and percutaneous revascularization, which has been improved tremendously over the last decades. Smoking cessation and regular exercise are the cornerstone for prevention of further cerebrovascular events. Medical treatment includes treatment of cardiovascular risk factors and antithrombotic management, which can be a challenge in some patients. Owing to the fact the coronary revascularization is readily accessible these days in many industrialized countries, the importance of antianginal therapy has decreased over the past years. This article presents a contemporary overview of the management of patients with stable angina in the year 2015.

We present an article viewer application that allows a scientific reader to easily discover and share knowledge by linking genomics-related concepts to knowledge of disparate biomedical databases. High-throughput data streams generated by technical advancements have contributed to scientific knowledge discovery at an unprecedented rate. Biomedical Informaticists have created a diverse set of databases to store and retrieve the discovered knowledge. The diversity and abundance of such resources present biomedical researchers a challenge with knowledge discovery. These challenges highlight a need for a better informatics solution. We use a text mining algorithm, Genomine, to identify gene symbols from the text of a journal article. The identified symbols are supplemented with information from the GenoDB knowledgebase. Self-updating GenoDB contains information from NCBI Gene, Clinvar, Medgen, dbSNP, KEGG, PharmGKB, Uniprot, and Hugo Gene databases. The journal viewer is a web application accessible via a web browser. The features described herein are accessible on www.genotation.org The Genomine algorithm identifies gene symbols with an accuracy shown by .65 F-Score. GenoDB currently contains information regarding 59,905 gene symbols, 5633 drug-gene relationships, 5981 gene-disease relationships, and 713 pathways. This application provides scientific readers with actionable knowledge related to concepts of a manuscript. The reader will be able to save and share supplements to be visualized in a graphical manner. This provides convenient access to details of complex biological phenomena, enabling biomedical researchers to generate novel hypothesis to further our knowledge in human health. This manuscript presents a novel application that integrates genomic, proteomic, and pharmacogenomic information to supplement content of a biomedical manuscript and enable readers to automatically discover actionable knowledge. © 2016 by the Society for Experimental Biology and

Hoy, Matthew B

2017-01-01

The high cost of journal articles has driven many researchers to turn to a new way of getting access: "pirate" article sites. Sci-Hub, the largest and best known of these sites, currently offers instant access to more than 58 million journal articles. Users attracted by the ease of use and breadth of the collection may not realize that these articles are often obtained using stolen credentials and downloading them may be illegal. This article will briefly describe Sci-Hub and how it works, the legal and ethical issues it raises, and the problems it may cause for librarians. Librarians should be aware of Sci-Hub and the ways it may change their patrons' expectations. They should also understand the risks Sci-Hub can pose to their patrons and their institutions.

Staying current with the literature is of paramount importance to the pharmacist engaged in an evidence-based clinical practice. Given the expanding roles and responsibilities of today's pharmacists combined with exponential growth in new medical and health sciences literature, staying current has become an extremely daunting task. Traditional journal clubs have focused upon their role as a training vehicle for teaching critical reading skills to residents. However, schools of pharmacy are now required to provide instruction in biostatistics, research design, and interpretation. We present a paradigm shift in the traditional journal club model whereby a collection of periodicals is screened and a short synopsis of the pertinent articles is provided. The associated tasks for screening and presenting of the primary literature are shared among a group of clinicians and trainees with similar practice interests resulting in a more reasonable workload for the individual. This journal club method was effective in identifying a significant majority of articles judged to be pertinent by independent groups of clinicians in the same practice arenas. Details regarding the shared core practice and knowledge base elements, journal club format, identification of journals, and evaluation of the success of the journal club technique are provided.

Brainstem tumors: Current management and future directions

Full Text Available Tumors arising in the brainstem comprise 10-20% of all pediatric central nervous system (CNS tumors and account for a small percentage in adults. The prognosis for these tumors was considered uniformly poor prior to the era of modern neuroimaging and the location was fraught with disaster being considered a ′no man′s land′ for neurosurgeons. Following the introduction of advanced imaging modalities and neurophysiological monitoring, striking progress has occurred in the management of these lesions. Brainstem tumors are presently classified based on their anatomic location, focality, and histopathology. This article reviews the current classification of brainstem tumors, current management options, and future directions in the treatment for these rare tumors.

This article is a translation of a French article by Delay, Brion, and Escourolle. In a seminal article published in French in 1957 these authors summarized the work of previous researchers and reviewed a wide sample of frontotemporal dementia (FTD) cases formerly referred to as Pick's disease. The authors were among the first to define the critical clinical and anatomical differences between Alzheimer's disease (AD) and FTD and they even delineated distinctive FTD subtypes making possible the advances that now constitute the base of our studies. Reviewing their work allows us to appreciate the progress research has made.

2014-04-01

To identify the 100 most cited articles published in dental journals. A search was performed on the Institute for Scientific Information (ISI) Web of Science for the most cited articles in all the journals included in the Journal Citation Report (2010 edition) in the category of "Dentistry, Oral Surgery, and Medicine". Each one of the 77 journals selected was analyzed using the Cited Reference Search tool of the ISI Web of Science database to identify the most cited articles up to June 2012. The following information was gathered from each article: names and number of authors, journal, year of publication, type of study, methodological design, and area of research. The number of citations of the 100 selected articles varied from 326 to 2050. All articles were published in 21 of the 77 journals in the category. The journals with the largest number of the cited articles were the Journal of Clinical Periodontology (20 articles), the Journal of Periodontology (18 articles), and the Journal of Dental Research (16 articles). There was a predominance of clinical research (66 %) over basic research (34 %). The most frequently named author was Socransky SS, with 9 of the top 100 articles, followed by Lindhe J with 7. The decades with most articles published of the 100 selected were 1980-1989 (26 articles) and 1990-1999 (25 articles). The most common type of article was the case series (22 %), followed by the narrative review/expert opinion (19 %). The most common area of study was periodontology (43 % of articles). To our knowledge, this is the first report of the top-cited articles in Dentistry. There is a predominance of clinical studies, particularly case series and narrative reviews/expert opinions, despite their low-evidence level. The focus of the articles has mainly been on periodontology and implantology, and the majority has been published in the highest impact factor dental journals. The number of citations that an article receives does not necessarily reflect the

The visibility of scientific misconduct: A review of the literature on retracted journal articles.

Hesselmann, Felicitas; Graf, Verena; Schmidt, Marion; Reinhart, Martin

2017-10-01

Retractions of scientific articles are becoming the most relevant institution for making sense of scientific misconduct. An increasing number of retracted articles, mainly attributed to misconduct, is currently providing a new empirical basis for research about scientific misconduct. This article reviews the relevant research literature from an interdisciplinary context. Furthermore, the results from these studies are contextualized sociologically by asking how scientific misconduct is made visible through retractions. This study treats retractions as an emerging institution that renders scientific misconduct visible, thus, following up on the sociology of deviance and its focus on visibility. The article shows that retractions, by highlighting individual cases of misconduct and general policies for preventing misconduct while obscuring the actors and processes through which retractions are effected, produce highly fragmented patterns of visibility. These patterns resemble the bifurcation in current justice systems.

Solar module quality - Response to an article on 'premature senile decay'

Rebmann, R.

2009-01-01

In this response to an article on the premature loss of power and reduction of the service-life of photovoltaic panels, the opinion is taken that the original article was too negative and one-sided. Certain action taken by individual manufacturers in that they withdrew from the market is quoted as not being representative for the whole solar business. Recent efforts in the quality assurance area are noted. The opinions stated in the original article on the topic of thin-film photovoltaics are looked at critically. Current testing and certification systems are considered as being able to provide security for customers.

World petroleum refining capacity: Present and forecasted situation

1991-01-01

World petroleum demand is expected to increase from about 15 million barrels to 80 million after the year 2000. The resulting necessity to increase the currently over-extended global refining capacity will put a significant burden on financial resources within the industry. This article examines the developments, after a decade of restructuring, which have led to the present situation of the petroleum industry described as having greatly improved operational conditions but beset by worrisome problems with regard not only to capacity, but also to the costly constraints being imposed by new air pollution regulations, especially those relevant to desulfurization in refinery processes

Writing a review article - Are you making these mistakes?

Science.gov (United States)

Daldrup-Link, Heike E

2018-01-01

An explosion of scientific publications over the last decades has increased the need for review articles: Carefully crafted scientific review articles can provide the novice reader with an overview of a new subject and provide the expert with a synthesis of scientific evidence, proof of reproducibility of published data and pooled estimates of common truth through meta-analyses. Unfortunately, while there are ample presentations and published guidelines for the preparation of scientific articles available, detailed information about how to properly prepare scientific review articles is relatively scarce. This perspective summarizes possible mistakes that can lead to misinformation in scientific review articles with the goal to help authors to improve the scientific contribution of their review article and thereby, increase the respective value of these articles for the scientific community.

Introduction of article-processing charges for Population Health Metrics

Murray Christopher JL

2003-11-01

Full Text Available Abstract Population Health Metrics is an open-access online electronic journal published by BioMed Central – it is universally and freely available online to everyone, its authors retain copyright, and it is archived in at least one internationally recognised free repository. To fund this, from November 1 2003, authors of articles accepted for publication will be asked to pay an article-processing charge of US$500. This editorial outlines the reasons for the introduction of article-processing charges and the way in which this policy will work. Waiver requests will be considered on a case-by-case basis, by the Editor-in-Chief. Article-processing charges will not apply to authors whose institutions are 'members' of BioMed Central. Current members include NHS England, the World Health Organization, the US National Institutes of Health, Harvard, Princeton and Yale universities, and all UK universities. No charge is made for articles that are rejected after peer review. Many funding agencies have also realized the importance of open access publishing and have specified that their grants may be used directly to pay APCs.

The french law of 1991, decided to define management solutions in the radioactive wastes management policy, is now over. The results of researches led to the promulgation of a new planing act, the law of the 28 June 2006. This law concerns the sustainable management of radioactive materials and wastes. It takes also in account a public debate, organized in September 2005 by the National Commission for Public Debate. The Law project architecture can be described in three main points: the implementing of a national policy of radioactive materials and wastes, a better transparency and democratic control and the implementing of specific modalities for the organization and the financing of spent fuels and radioactive wastes management. This document presents what is in the different articles, with a special attention to the contributions of the parliamentary debate. (A.L.B.)

The purpose of this study was to use Web of Knowledge to determine which published arthroscopic surgery-related articles have been cited most frequently by other authors by ranking the 25 most cited articles. We furthermore wished to determine whether there is any difference between a categorical "journal-by-journal" analysis and an "all-database" analysis in arthroscopic surgery and whether such a search methodology would alter the results of previously published lists of "citation classics" in the field. We analyzed the characteristics of these articles to determine what qualities make an article important to this subspecialty of orthopaedic surgery. Web of Knowledge was searched on March 7, 2011, using the term "arthroscopy" for citations to articles related to arthroscopy in 61 orthopaedic journals and using the all-database function. Each of the 61 orthopaedic journals was searched separately for arthroscopy-related articles to determine the 25 most cited articles. An all-database search for arthroscopy-related articles was carried out and compared with a journal-by-journal search. Each article was reviewed for basic information including the type of article, authorship, institution, country, publishing journal, and year published. The number of citations ranged from 189 to 567 in a journal-by-journal search and from 214 to 1,869 in an all-database search. The 25 most cited articles on arthroscopic surgery were published in 11 journals: 8 orthopaedic journals and 3 journals from other specialties. The most cited article in arthroscopic orthopaedic surgery was published in The New England Journal of Medicine, which was not previously identified by a journal-by-journal search. An all-database search in Web of Knowledge gives a more in-depth methodology of determining the true citation ranking of articles. Among the top 25 most cited articles, autologous chondrocyte implantation/transplantation is currently the most cited and most popular topic in arthroscopic

Full Text Available This article aims to analyze motivations behind social sciences blog posts citing journal articles in order to find out whether blog citations of scholarly journal articles are good indicators for the societal impact of research. A random sample of 300 social sciences blog posts (out of 1,233 blog posts from ResearchBlogging published between 01/01/2012 to 18/06/2014 were subjected to content analysis. An existing categorization scheme was used and modified inductively. The 300 blog posts had 472 references including 424 journal articles from 269 different journals. Sixty-one (22.68% of all journals cited were from the category of social sciences and most of the journals with high frequency were highly cited general science journals such as PNAS and Science. Seventy-five percent of all journals were referenced only once. The average age of articles cited was 5.8 years. The most frequent (38, 12.67% motivation was to ‘neutrally presenting details of a study’. Overall, social science blogs were rather subject-oriented than article oriented. This means a considerable number of blog posts were not driven simply by writing about an article, instead bloggers tend to write about their subject of interest and use references to support their argument. The study shows the potential of blog citations as an altmetric measure and as a proxy for assessing the research impact.

Wilson, M K; Chestnutt, I G

2016-03-01

Evidence to inform clinical practice is reliant on research carried out using appropriate study design. The objectives of this work were to (i) identify the prevalence of articles reporting on human studies using uncontrolled intervention or observational research designs published in peer-reviewed dental journals and (ii) determine the nature of recommendations made by these articles. Six peer-reviewed dental journals were selected. Issues published in January to June 2013 were examined and the types of articles published categorized. Following pre-defined inclusion/exclusion criteria, human studies classified as using uncontrolled intervention or observational research designs were subject to detailed review by two independent investigators, to examine if they presented clinical, policy or research recommendations and if these recommendations were supported by the data presented. 52.9% (n = 156) of studies published during the time period met the inclusion criteria. Studies with uncontrolled intervention or observational research designs comprised a larger proportion of the primary research studies published in the journals with lower impact factors (73.3%; n = 107) compared to the high impact journals (38.9%; n = 49). Analysis showed that 60.9% (n = 95) of the included studies made recommendations for clinical practice/dental policy. In 28.2% (n = 44) of studies, the clinical/policy recommendations made were judged to not be fully supported by the data presented. Many studies published in the current dental literature, which are not considered to produce strong evidence, make recommendations for clinical practice or policy. There were some cases when the recommendations were not fully supported by the data presented. Copyright © 2016 Elsevier Inc. All rights reserved.

The current volume of the Parmenides Series "On Thinking" addresses our deepest and most personal experience of the world, the experience of "the present," from a modern perspective combining physics and philosophy. Many prominent researchers have contributed articles to the volume, in which they present models and express their opinions on and, in some cases, also their skepticism about the subject and how it may be (or may not be) addressed, as well as which aspects they consider most relevant in this context. While Einstein might have once hoped that "the present" would find its place in

Visualizing Article Similarities via Sparsified Article Network and Map Projection for Systematic Reviews.

Ji, Xiaonan; Machiraju, Raghu; Ritter, Alan; Yen, Po-Yin

2017-01-01

Systematic Reviews (SRs) of biomedical literature summarize evidence from high-quality studies to inform clinical decisions, but are time and labor intensive due to the large number of article collections. Article similarities established from textual features have been shown to assist in the identification of relevant articles, thus facilitating the article screening process efficiently. In this study, we visualized article similarities to extend its utilization in practical settings for SR researchers, aiming to promote human comprehension of article distributions and hidden patterns. To prompt an effective visualization in an interpretable, intuitive, and scalable way, we implemented a graph-based network visualization with three network sparsification approaches and a distance-based map projection via dimensionality reduction. We evaluated and compared three network sparsification approaches and the visualization types (article network vs. article map). We demonstrated the effectiveness in revealing article distribution and exhibiting clustering patterns of relevant articles with practical meanings for SRs.

To investigate the current prevalence of open access (OA) in the field of dentistry, the means used to provide OA, as well as the association between OA and citation counts. PubMed was searched for dental articles published in 2013. The OA status of each article was determined by manually checking Google, Google Scholar, PubMed and ResearchGate. Citation data were extracted from Google Scholar, Scopus and Web of Science. Chi-square tests were used to compare the OA prevalence by different subjects, study types, and continents of origin. The association between OA and citation count was studied with multivariable logistic regression analyses. A random sample of 908 articles was deemed eligible and therefore included. Among these, 416 were found freely available online, indicating an overall OA rate of 45.8%. Significant difference in OA rate was detected among articles in different subjects (Pdentistry, 54% of recent journal articles are behind the paywall (non-OA) one year after their publication dates. The 'Green road' of providing OA was more common than the 'Gold road'. No evidence suggested that OA articles received significantly more citations than non-OA articles.

Full Text Available This article discuss about Article 27 of Law No. 5 Year 1999 on the Restriction of Monopoly Practices and Unfair Business Practices (“Competition Law”. One may wonder the rigorousness to the application of Article 27 which arguably could ban any merger which meets market test without conducting any competitive assessment. For this, the law has been presumed that the acquisition or controlling of large market share from merger is per se illegality. Further, the effects of Article 27 would be discussed in this paper. A merger review itself is not an easy task and tends to bring complex issues that one needs to be dealt with. Things get more complicated when one deals with the merger application in developing countries since there are various aspects that need to be taken account by the respective antitrust authority (including Indonesia Obviously, every country needs to set up its competition law in accordance with its own economic characteristics and conditions. Many have argued as to point out the severe condition in market as a result of high concentration of competition. But more of them argued otherwise, as it could positively pushed on the market. This article would also include best practices from US and EU competition law practices regarding the issue at hand, as well as the relationship of merger control and practices in developing countries. The article offers suggestion with regard to the current approach to Article 27 of the Competition Law and from EU and US best practice which could be used for the benefit of Indonesia’s competition law especially to the application of Article 27.

The Peer Education Approach in Adolescents- Narrative Review Article.

Science.gov (United States)

Abdi, Fatemeh; Simbar, Masoumeh

2013-11-01

Adolescence is an important stage of human life span, which crucial developmental processes occur. Since peers play a critical role in the psychosocial development of most adolescents, peer education is currently considered as a health promotion strategy in adolescents. Peer education is defined as a system of delivering knowledge that improves social learning and provides psychosocial support. As identifying the outcomes of different educational approaches will be beneficial in choosing the most effective programs for training adolescents, the present article reviewed the impact of the peer education approach on adolescents. In this review, databases such as PubMed, EMBASE, ISI, and Iranian databases, from 1999 to 2013, were searched using a number of keywords. Peer education is an effective tool for promoting healthy behaviors among adolescents. The development of this social process depends on the settings, context, and the values and expectations of the participants. Therefore, designing such programs requires proper preparation, training, supervision, and evaluation.

We present the overall conductance as well as the circulating currents in individual loops of a Sierpinski gasket (SPG) as we apply bias voltage via the side attached electrodes. SPG being a self-similar structure, its manifestation on loop currents and magnetic fields is examined in various generations of this fractal and it has been observed that for a given configuration of the electrodes, the physical quantities exhibit certain regularity as we go from one generation to another. Also a notable feature is the introduction of anisotropy in hopping causes an increase in magnitude of overall transport current. These features are a subject of interest in this article. - Highlights: • Voltage driven circular current is analyzed in a fractal network. • Current induced magnetic field is strong enough to flip a spin. • Anisotropy in hopping enhances overall transport current.

Method for providing uranium articles with a corrosion resistant anodized coating

International Nuclear Information System (INIS)

Waldrop, F.B.; Washington, C.A.

1982-01-01

Uranium articles are provided with anodized oxide coatings in an aqueous solution of an electrolyte selected from the group consisting of potassium phosphate, potassium hydroxide, ammonium hydroxide, and a mixture of potassium tetraborate and boric acid. The uranium articles are anodized at a temperature greater than about 75 degrees C. With a current flow of less than about 0.036 A/cm2 of surface area while the Ph of the solution is maintained in a range of about 2 to 11.5. The Ph values of the aqueous solution and the low current density utilized during the electrolysis prevent excessive dissolution of the uranium and porosity in the film or watering. The relatively high temperature of the electrolyte bath inhibits hydration and the attendant deleterious pitting so as to enhance corrosion resistance of the anodized coating

2012-04-01

The first phase of Elsevier's Article of the Future article format was released on SciVerse ScienceDirect in January 2012. While this new format for online scholarly articles brings a significantly improved online presentation, it also enables further enhancements in terms of domain-specific content and contextualization of research results. Of particular interest to the Earth Sciences research community are the seamless integration of an interactive map viewer that displays author-submitted KML files inside the article, and real-time links to leading research data portals like Pangaea and Earthchem. These enhancements allow for a richer form of communication between authors and readers, and present researchers with valuable additional information in the context of the article. In this presentaion I will review these ongoing efforts to enhance online articles in the digital era.

Female pattern alopecia: current perspectives

Science.gov (United States)

Levy, Lauren L; Emer, Jason J

2013-01-01

Hair loss is a commonly encountered problem in clinical practice, with men presenting with a distinctive pattern involving hairline recession and vertex balding (Norwood-Hamilton classification) and women exhibiting diffuse hair thinning over the crown (increased part width) and sparing of the frontal hairline (Ludwig classification). Female pattern hair loss has a strikingly overwhelming psychological effect; thus, successful treatments are necessary. Difficulty lies in successful treatment interventions, as only two medications – minoxidil and finasteride – are approved for the treatment of androgenetic alopecia, and these medications offer mediocre results, lack of a permanent cure, and potential complications. Hair transplantation is the only current successful permanent option, and it requires surgical procedures. Several other medical options, such as antiandrogens (eg, spironolactone, oral contraceptives, cyproterone, flutamide, dutasteride), prostaglandin analogs (eg, bimatoprost, latanoprost), and ketoconazole are reported to be beneficial. Laser and light therapies have also become popular despite the lack of a profound benefit. Management of expectations is crucial, and the aim of therapy, given the current therapeutic options, is to slow or stop disease progression with contentment despite patient expectations of permanent hair regrowth. This article reviews current perspectives on therapeutic options for female pattern hair loss. PMID:24039457

2017-10-25

Background Bibliometric science employs statistical and quantitative analyses to analyse the scholarly impact and characteristics of publications within a research field. The present study was initiated to analyse and quantify the 100 most often cited papers in glaucoma research. Materials and Methods The databases of the Institute for Scientific Information were utilised for the identification of articles published from 1900 to December 2016. All glaucoma articles were identified that had been published in 109 relevant journals and which had been cited at least 200 times. The top 100 articles were selected for further analysis of authorship, source journal, number of citations, citation rate, geographic origin, article type, and level of evidence. Results The publication dates of the 100 most often cited articles ranged from 1966 to 2011, with the greatest number of articles published in the 1990s. Citations per article ranged from 258 to 1908. All articles were published in 18 of the 109 journals. The leading countries of origin were the U. S. A., followed by the U. K. The study focussed on two main clinical articles (diagnostics; epidemiology) and basic research articles. The number of citations per article was greatest for articles published in the 2000s. Most articles provided level III evidence, followed by levels I and II. Conclusion The majority of the most cited articles were published in three of the top-ranked journals. Most clinical articles dealt with epidemiology and diagnostics. Individuals who authored multiple articles in the list often focussed on one of these two areas. Most studies were conducted in the U. S. A. and presented level III clinical outcomes. This indicates that even studies with small case series or cohort studies can attract attention.

Current Medical Journalism Needs Major Revisions

Directory of Open Access Journals (Sweden)

Full Text Available Medical journalism commenced during early nineteenth century as an impressive adjunct for medical education. It is considered as a platform to share the results of the research studies and to disseminate medical information that could impact the present concept and practice of the medicine field. Medical journalism gained immense attention over the years; however, the present scenario revealed certain limitations. A rise in the number of researchers, by interest or forcefully, has led to an increase in the journal count, resulting in several fake research articles being published in the journals. This leads to inappropriate research and low quality of journals, where the data appearing in the research articles is not authentic; thus, the journals publishing such articles face several issues while verifying the authenticity of the data provided. All journals, in particular, the recent ones strive to achieve immense importance in regards to the impact factor, h-index, and similar quality assessments; however, attaining similar scores as that of the well-known journals is impossible. Hence, as a futile effort, the editorial team of the new or latest journals consider adding more references in their articles in order to achieve a higher score; however, certain references from the previously published papers, may decode as a conflict of interest. Based on an unwritten and unavailable rule, all new journals try to publish papers in same format as publishing in famous journals, and do not dare to deconstruct it. It seems that deconstruction should also be performed by the old journals founded the current style! In order to avoid the aforementioned issues, the Advanced Journal of Emergency Medicine emerged with the concept of being different, deconstructive, and without any futile competition with the other journals. Accordingly, we consider a large audience with several degrees of medical education to participate in the field of research, make the

Río, Jordi; Montalbán, Xavier

2014-12-01

Multiple sclerosis is a multifocal demyelinating disease leading to progressive neurodegeneration caused by an autoimmune response in genetically predisposed individuals. In the last few years, the knowledge and management of this disease has been revolutionized by a series of findings. The present article reviews pathological features of the disease, in which cortical involvement is increasingly implicated, and aspects related to novel pathogenic mechanisms, such as the role of the microbiota in the genesis of multiple sclerosis, as well as recent contributions from the fields of epidemiology and genetics. Also reviewed are the latest diagnostic criteria, which currently allow a much earlier diagnosis, with clear therapeutic implications. Copyright © 2014 Elsevier España, S.L.U. All rights reserved.

A PICTORIAL PRESENTATION OF ESOPHAGEAL HIGH RESOLUTION MANOMETRY CURRENT PARAMETERS.

Science.gov (United States)

Lafraia, Fernanda M; Herbella, Fernando A M; Kalluf, Julia R; Patti, Marco G

2017-01-01

High resolution manometry is the current technology used to the study of esophageal motility and is replacing conventional manometry in important centers for esophageal motility with parameters used on esophageal motility, following the Chicago Classification. This classification unifies high resolution manometry interpretation and classifies esophageal disorders. This review shows, in a pictorial presentation, the new parameters established by the Chicago Classification, version 3.0, aimed to allow an easy comprehension and interpretation of high resolution manometry. Esophageal manometries performed by the authors were reviewed to select illustrative tracings representing Chicago Classification parameters. The parameters are: Esophagogastric Morphology, that classifies this junction according to its physiology and anatomy; Integrated Relaxation Pressure, that measures the lower esophageal sphincter relaxation; Distal Contractile Integral, that evaluates the contraction vigor of each wave; and, Distal Latency, that measures the peristalsis velocity from the beginning of the swallow to the epiphrenic ampulla. Clinical applications of these new concepts is still under evaluation. Mostrar, de forma pictórica, os novos parâmetros compilados na versão 3.0 da Classificação de Chicago, buscando facilitar a compreensão e interpretação da manometria de alta resolução. Foram revistas as manometrias da casuística dos autores e selecionados os traçados representativos dos parâmetros da Classificação de Chicago. Entre os parâmetros apresentados foram considerados a Morfologia da Transição Gastroesofágica, que classifica o segmento de acordo com sua fisiologia e anatomia; a Integral da Pressão de Relaxamento, que mede o relaxamento do esfíncter esofagiano inferior; a Integral Contrátil Distal, que avalia o vigor contrátil da onda peristáltica; e, a Latência Distal, que mede o tempo da peristalse, desde o início da deglutição até a ampola epifr

Prior research shows that article reader counts (i.e. saves) on the online reference manager, Mendeley, correlate to future citations. There are currently no evidenced-based distribution strategies that have been shown to increase article saves on Mendeley. We conducted a 4-week randomized controlled trial to examine how promotion of article links in a novel online cross-publisher distribution channel (TrendMD) affect article saves on Mendeley. Four hundred articles published in the Journal of Medical Internet Research were randomized to either the TrendMD arm ( n  = 200) or the control arm ( n  = 200) of the study. Our primary outcome compares the 4-week mean Mendeley saves of articles randomized to TrendMD versus control. Articles randomized to TrendMD showed a 77% increase in article saves on Mendeley relative to control. The difference in mean Mendeley saves for TrendMD articles versus control was 2.7, 95% CI (2.63, 2.77), and statistically significant ( p  < 0.01). There was a positive correlation between pageviews driven by TrendMD and article saves on Mendeley (Spearman's rho r  = 0.60). This is the first randomized controlled trial to show how an online cross-publisher distribution channel (TrendMD) enhances article saves on Mendeley. While replication and further study are needed, these data suggest that cross-publisher article recommendations via TrendMD may enhance citations of scholarly articles.

The top 100 cited articles on urological emergencies: A bibliometric analysis.

Science.gov (United States)

Kazımoğlu, Hatem; Dokur, Mehmet

2018-05-01

In this study, we bibliometrically evaluated the top 100 cited articles on urological emergencies published since 1975 with a multidisciplinary and interdisciplinary perspective. We obtained the data for this study from the Thomson Reuters Web of Science and PubMed. We determined 360 articles which were related directly or indirectly to urological emergencies between 1975 and 2017 and analyzed retrospectively the top 100 cited articles among these. The mean citation impact factor of the top 100 cited articles was 25.8±50.1 (range: 4-467) between 1991 and 2014. We determined that classical articles were cited for 2588 times and the total number of self-citations was 23 (0.8%). Highest publication rate per year was in 2006 (n=9). Among the institutions which published ≥2 articles per year University of Texas led the way with 5 articles. The top 100 articles came from 27 countries and 58% of these are from the USA (n=29), the United Kingdom (n=23) and Germany (n=6). For the top 3 journals of the 33 of top 100 articles most frequently cited were published in journals with an impact factor ≥2 namely, Journal of Urology (n=15), British Journal of Urology International (n=13) and Urology (n=5) respectively. The most frequently cited main topics were penile emergencies with 22 articles and acute scrotal problems with 15 articles. Most of the classical articles on urological emergencies were based on clinical researches (n=95) and also we found that the average level of evidence for the top 100 cited articles was 4.16 (range: 1-5). Mostly preferred publishing language was English among this scientific papers (n=90). Although not considered as a completely unbiased and adequate criterion for scientific evaluations, analysis of the top 100 cited articles provides us with important current data on urological emergencies.

Method for hot pressing irregularly shaped refractory articles

Steinkamp, William E.; Ballard, Ambrose H.

1982-01-01

The present invention is directed to a method for hot pressing irregularly haped refractory articles with these articles of varying thickness being provided with high uniform density and dimensional accuracy. Two partially pressed compacts of the refractory material are placed in a die cavity between displaceable die punches having compact-contacting surfaces of the desired article configuration. A floating, rotatable block is disposed between the compacts. The displacement of the die punches towards one another causes the block to rotate about an axis normal to the direction of movement of the die punches to uniformly distribute the pressure loading upon the compacts for maintaining substantially equal volume displacement of the powder material during the hot pressing operation.

Brinjikji, Waleed; Klunder, Alexa; Kallmes, David F

2013-10-01

To characterize the 100 most-cited articles in medical imaging. The Scopus database was searched for citations to articles published in any of the 116 journals in the subject category "radiology, nuclear medicine, and medical imaging" at the Institute of Science Information Web of Science that the authors termed "imaging literature." Using the Scopus database, two authors searched electronic and print versions of these journals to determine the 100 most-cited articles. The following data were collected for each article: journal name, journal impact factor, number of authors, publication year, country in which the study was performed, department of all authors, article type, imaging modality, grant funding, and clinical subspecialty. Statistical and/or mathematic, magnetic resonance (MR) imaging technique, image processing and/or analysis and computer science, new imaging technique, and basic science articles were considered "preclinical." Using the Pearson correlation coefficient, the authors examined the relationship between journal impact factor and the number of top 100 cited articles included in the list. Most studies were classified as preclinical (n = 75). Fifty-eight of the 100 articles were neuroradiology articles. NeuroImage had the most highly cited articles (n = 22). MR imaging was the most commonly studied imaging modality (n = 69). The authors of 51 articles were from radiology departments. Most articles were published from 1990 to the present (n = 87). There was a statistically significant positive correlation between journal impact factor and the number of top 100 cited articles (r = 0.46, P < .001). Preclinical articles, primarily in the field of neurologic MR imaging, were highly represented in the top 100 cited articles in the medical imaging literature. © RSNA, 2013.

SUPPLEMENARY COMMUNICATIVE UNITS IN NEWSPAPER ARTICLES OF DIFFERENT GENRES

Directory of Open Access Journals (Sweden)

Elena Yurievna Viktorova

2014-11-01

Full Text Available The article studies the role of supplementary communicative units functioning as discourse markers in analytical articles and opinion columns of modern Russian and English newspapers. The dependence of quantitative and qualitative characteristics of different supplementary communicative units on the type of the article and on the language is discussed. The article proves that the use of supplementary units in opinion columns in Russian and in English has more common features than in analytical articles. The highest frequency of occurrence of these units is registered in Russian analytical articles, the lowest – in English articles. In Russian newspapers analytical articles and columns demonstrate more similar characteristics than in English materials. Supplementary communicative units with organizing functions occur more frequently in Russian articles, in English articles and columns they are equally rare. Regulative supplementary units are used equally often in all analyzed newspaper texts. There is a conclusion that regulative supplementary units tend to be more universal in their use in the two languages, while organizing units show greater dependence on the language. The presented analysis of the supplementary communicative units’ use can become one of the ways to take an inventory of persuasive language means in media discourse. These units produce a productive influence on the readers, help them interpret the text adequately; enhance their attention and mental activity.

E-waste is one of the fastest-growing waste streams in Iran, owing to an increase in consumption of electrical and electronic equipment. Nevertheless, as is the case in some other countries, E-waste management has not received sufficient attention. For the successful implementation of any waste management plan (including an E-waste management plan), the availability of sufficient and accurate information on the quantities and composition of the waste generated and on current management conditions is a fundamental prerequisite. At present, in Iran, there is no available and accurate information that describes the characteristics and generation rate of E-waste or the actual practice of management and handling of the waste. For this initial study, eight electronic products were selected for the determination of their E-waste generation rate in the country, and two cities, Tehran and Tabriz, were selected for assessment of the current condition of E-waste management. The study found that the amount of E-waste generation in the country for the eight selected electronic items alone was 115,286, 112,914 and 115,151 metric tons in 2008, 2009 and 2010, respectively. Of the types of electronic items included in the study, televisions, with an average of 42.42%, and PCs, with an average of 32.66% accounted for the greatest proportions of the total mass of E-waste generated during 2008-2010. Currently, despite the fact that primary legislation for E-waste management (as part of general waste legislation) exists in Iran, this primary legislation has not yet been implemented. In practical terms, there is no definite policy or plan for the allocation of funds to prepare suitable equipment and facilities for the management and recycling of E-waste at the end of the products' useful life. Proposed improvements in current conditions are identified, first by considering other countries' experiences and then suggesting specific practical policies, rules, and regulations that should be

Japanese and international standards related to radiation control and radiation protective management are presented focusing on the forming condition, significance, current situation, and their relationship. Japanese Industrial Standards (JIS) is quite useful in the field of atomic energy as well as other fields in terms of optimization and rationalization of the management. JIS includes JIS Z 4001 Atomic Energy Terminology which corresponds to internationl standards ISO 921 Nuclear Glossary, and JIS Z 4005 Medical Radiation Terminology, covering about 500 articles, which corresponds to IEC 788 Medical Radiology-Terminology. The first standards regarding radiation protection was established in X-ray Film Badge, which is included in the field of personal dosimeter, in 1956. Currently, 36 JIS has been established in the field of radiation management dosimeter and 3 are under arrangement. As for radiation protective supplies, 9 JIS has been established so far. Before proposal of JIS, investigation had been conducted to improve, simplify, and standardize the standards of radiation dosimetric technique, dosimeters, dosimetric procedures, and improvement. In this article, the results of material surface contamination monitoring and body surface monitoring conducted in Atomic Energy Safety Association and Radiation Dosimetry Associationare reported, and ISO and IEC are also treated.

We review the status of the Cabibbo-Kobayashi-Maskawa (CKM) matrix elements and the CP-violating phases in the CKM-unitarity triangle. The emphasis in these lecture notes is on B-meson physics, through we also review the current status and issues in the light quark sector of this matrix. Selected applications of theoretical methods in QCD used in the interpretation of data are given and some of the issues restricting the theoretical precision on the CKM matrix elements discussed. The overall consistency of the CKM theory with the available data in flavour physics is impressive and we quantify this consistency. Current data also show some anomalies which, however, are not yet statistically significant. They are discussed briefly. some benchmark measurements that remain to be done in experiments at the B-factories and hadron colliders are listed. Together with the already achieved results, they will provide unprecedented test of the CKM theory and by the same token may lead to the discovery of new physics. (Author) 284 refs

Much research has been done in Northeast Asia to show the efficacy of traditional medicine. While MEDLINE contains many biomedical articles including those on traditional medicine, it does not categorize those articles by specific research area. The aim of this study was to provide a method that searches for articles only on traditional medicine in Northeast Asia, including traditional Chinese medicine, from among the articles in MEDLINE. This research established an SVM-based classifier model to identify articles on traditional medicine. The TAK + HM classifier, trained with the features of title, abstract, keywords, herbal data, and MeSH, has a precision of 0.954 and a recall of 0.902. In particular, the feature of herbal data significantly increased the performance of the classifier. By using the TAK + HM classifier, a total of about 108,000 articles were discriminated as articles on traditional medicine from among all articles in MEDLINE. We also built a web server called DisArticle ( http://informatics.kiom.re.kr/disarticle ), in which users can search for the articles and obtain statistical data. Because much evidence-based research on traditional medicine has been published in recent years, it has become necessary to search for articles on traditional medicine exclusively in literature databases. DisArticle can help users to search for and analyze the research trends in traditional medicine.

To assist the pharmacy clinician engaged in nutrition support in staying current with the most pertinent literature. Several experienced board-certified clinical pharmacists engaged in nutrition support therapy compiled a list of articles published in 2014 and 2015 that they considered to be important to their practice. Only those articles available in print format were considered for potential inclusion. Articles available only in preprint electronic format were not evaluated. The citation list was compiled into a single spreadsheet where the author participants were asked to ascertain whether they considered the paper important to nutrition support pharmacy practice. A culled list of publications was then identified whereby the majority of author participants (at least 5 out of 8) considered the paper to be important. A total of 108 articles were identified; 36 of which were considered to be of high importance. An important guideline article published in early 2016, but not ranked, was also included. The top-ranked articles from the primary literature were reviewed. It is recommended that the informed pharmacist, who is engaged in nutrition support therapy, be familiar with the majority of these articles.

Louder than words: power and conflict in interprofessional education articles, 1954-2013.

Science.gov (United States)

Paradis, Elise; Whitehead, Cynthia R

2015-04-01

Interprofessional education (IPE) aspires to enable collaborative practice. Current IPE offerings, although rapidly proliferating, lack evidence of efficacy and theoretical grounding. Our research aimed to explore the historical emergence of the field of IPE and to analyse the positioning of this academic field of inquiry. In particular, we sought to investigate the extent to which power and conflict - elements central to interprofessional care - figure in the IPE literature. We used a combination of deductive and inductive automated coding and manual coding to explore the contents of 2191 articles in the IPE literature published between 1954 and 2013. Inductive coding focused on the presence and use of the sociological (rather than statistical) version of power, which refers to hierarchies and asymmetries among the professions. Articles found to be centrally about power were then analysed using content analysis. Publications on IPE have grown exponentially in the past decade. Deductive coding of identified articles showed an emphasis on students, learning, programmes and practice. Automated inductive coding of titles and abstracts identified 129 articles potentially about power, but manual coding found that only six articles put power and conflict at the centre. Content analysis of these six articles revealed that two provided tentative explorations of power dynamics, one skirted around this issue, and three explicitly theorised and integrated power and conflict. The lack of attention to power and conflict in the IPE literature suggests that many educators do not foreground these issues. Education programmes are expected to transform individuals into effective collaborators, without heed to structural, organisational and institutional factors. In so doing, current constructions of IPE veil the problems that IPE attempts to solve. © 2015 The Authors Medical Education Published by John Wiley & Sons Ltd.

There are important landmarks in their article on a disorder of the neuromuscular junction associated with thoracic neoplasm and the electrophysiological criteria for Lambert-Eaton myasthenic syndrome (LEMS). After 60 years, the main electrophysiological criteria described in Eaton and Lambert's pioneering article are still currently useful in the diagnosis of LEMS.

The Top 50 Articles on Minimally Invasive Spine Surgery.

Science.gov (United States)

Virk, Sohrab S; Yu, Elizabeth

2017-04-01

Bibliometric study of current literature. To catalog the most important minimally invasive spine (MIS) surgery articles using the amount of citations as a marker of relevance. MIS surgery is a relatively new tool used by spinal surgeons. There is a dynamic and evolving field of research related to MIS techniques, clinical outcomes, and basic science research. To date, there is no comprehensive review of the most cited articles related to MIS surgery. A systematic search was performed over three widely used literature databases: Web of Science, Scopus, and Google Scholar. There were four searches performed using the terms "minimally invasive spine surgery," "endoscopic spine surgery," "percutaneous spinal surgery," and "lateral interbody surgery." The amount of citations included was averaged amongst the three databases to rank each article. The query of the three databases was performed in November 2015. Fifty articles were selected based upon the amount of citations each averaged amongst the three databases. The most cited article was titled "Extreme Lateral Interbody Fusion (XLIF): a novel surgical technique for anterior lumbar interbody fusion" by Ozgur et al and was credited with 447, 239, and 279 citations in Google Scholar, Web of Science, and Scopus, respectively. Citations ranged from 27 to 239 for Web of Science, 60 to 279 for Scopus, and 104 to 462 for Google Scholar. There was a large variety of articles written spanning over 14 different topics with the majority dealing with clinical outcomes related to MIS surgery. The majority of the most cited articles were level III and level IV studies. This is likely due to the relatively recent nature of technological advances in the field. Furthermore level I and level II studies are required in MIS surgery in the years ahead. 5.

Stoneking, Lisa R; Grall, Kristi H; Min, Alice A; Panchal, Ashish R

2013-01-01

Many clinicians have difficulties reading current best practice journal articles on a regular basis. Discussion boards are one method of online asynchronous learning that facilitates active learning and participation. We hypothesized that an online repository of best practice articles with a discussion board would increase journal article reading by emergency medicine residents. PARTICIPANTS ANSWERED THREE QUESTIONS WEEKLY ON A DISCUSSION BOARD: What question does this study address? What does this study add to our knowledge? How might this change clinical practice? A survey regarding perceived barriers to participating was then distributed. Most participants completed an article summary once or twice in total (23/32, 71.9%). Only three were involved most weeks (3/32, 9.4%) whereas 5/32 (15.6%) participated monthly. The most common barriers were lack of time (20/32, 62.5%), difficulty logging on (7/32, 21.9%), and forgetting (6/32, 18.8%). Although subjects were provided weekly with an article link, email, and feedback, journal article reading frequency did not increase.

Improving your journal article using feedback from peer review.

Science.gov (United States)

Price, Bob

2014-09-30

While preparation of a journal article for submission may often include informal review by colleagues, an article is not accepted for publication until it has been formally peer reviewed. Peer review is the process whereby journal editors ask expert reviewers to examine the work submitted and prepare a report on its suitability for publication. Two or more revisions of the article may be required following peer review, with the author reworking the article in the light of feedback received on each occasion. This can be challenging for some authors, but used well, it offers a chance to improve the work to the required standard of the journal, and help the author present a more precise and coherent account of the arguments. The extent to which the author responds to the critical commentary of peer reviewers is important, because this may determine whether or not the article is published. This article explores the aims of peer reviewers and recommends ways in which authors can respond to the feedback provided.

RETRACTED ARTICLE: Personal distress, but not sympathy, predicts the negative influence of bystanders on responding to an emergency.

Science.gov (United States)

2015-06-01

At the request of the authors this article has been retracted. During the preparation of a follow-up study, a mistake was found in the experimental script of the cued reaction time task of experiment 2. Four out of six conditions were mislabeled. Consequently, the reported findings and their interpretation and discussion are incorrect. Careful reexamination and reanalyzing of the data using the correct labels revealed a pattern of results that is not entirely compatible with several of the main claims of the article. Importantly, the corrected results show that reaction times do not increase with more bystanders present at an emergency.Moreover, not only personal distress but also perspective taking predicts the negative influence of bystanders on reaction times.We believe that these new findings undermine our central claim of decreased action preparation as a function of bystanders present at an emergency and the enhancement of this effect in people with higher levels of trait personal distress. While the results and discussion of experiment 1 and 3 remain correct, the new results of experiment 2 influence the article to such an extent that we currently see no other option than to retract the article from publication. We will continue to work on this topic and hope to publish the new results in due time. We deeply regret the publication of invalid results.We sincerely apologize to the Editor and reviewers of the manuscript, and the readers of Cognitive, Affective, & Behavioral Neuroscience.

The Japanese artificial organs scene: current status.

Mitamura, Yoshinori; Murabayashi, Shun

2005-08-01

Artificial organs and regenerative medicine are the subjects of very active research and development (R&D) in Japan and various artificial organs are widely used in patients. Results of the R&D are presented at the annual conference of the Japanese Society for Artificial Organs (JSAO). Progress in the fields of artificial organs and regenerative medicine are reviewed annually in the Japanese Journal of Artificial Organs. The official English-language journal of JSAO, Journal of Artificial Organs, also publishes many original articles by Japanese researchers. Although the annual conference and the publications of JSAO provide the world with update information on artificial organs and regenerative medicine in Japan, the information is not always understood appropriately in the rest of the world, mainly due to language problems. This article therefore introduces the current status of artificial organs and regenerative medicine in Japan. Artificial hearts and metabolic support systems are reviewed here and other interesting areas such as regenerative medicine can be found elsewhere.

Exploring the evidence in pediatric hematology and oncology nursing through the "article of the month".

Science.gov (United States)

Linder, Lauri

2010-01-01

As the scope of pediatric hematology and oncology nursing expands, nurses are challenged with staying current in the evidence guiding their practice. Nurse-reported barriers to accessing and utilizing research include lack of time as well as difficulty in accessing, understanding, and synthesizing findings. Journal clubs provide a process to guide nurses in the review of current literature related to their practice and promote utilization of research and evidence-based practice among nurses. This article describes the transition of an in-person journal club to an electronically delivered "Article of the Month." The "Article of the Month" is offered six times each year and is posted on the service line's password-protected intranet website. Oversight of the "Article of the Month" is provided by the service line clinical nurse specialist who selects articles based on an annual learning needs assessment and develops a quiz to assess learning and promote critical thinking among nursing staff. Outcomes include anecdotal reports of increased staff confidence in managing emergent patient care needs and greater appreciation of nursing care issues for children with cancer. Areas for future development include exploring options for increasing in-person discussion of issues addressed in the "Article of the Month" among staff members, extending the "Article of the Month" to nurses in other service areas who care for children with cancer, and increasing staff participation in article selection and quiz item development. An ultimate goal is to develop formal evaluation strategies to link this educational strategy to clinical outcomes.

United Nations Charter, Chapter VII, Article 43: Now or Never.

Science.gov (United States)

Burkle, Frederick M

2018-04-25

For more than 75 years, the United Nations Charter has functioned without the benefit of Chapter VII, Article 43, which commits all United Nations member states "to make available to the Security Council, on its call, armed forces, assistance, facilities, including rights of passage necessary for the purpose of maintaining international peace and security." The consequences imposed by this 1945 decision have had a dramatic negative impact on the United Nation's functional capacity as a global body for peace and security. This article summarizes the struggle to implement Article 43 over the decades from the onset of the Cold War, through diplomatic attempts during the post-Cold War era, to current and often controversial attempts to provide some semblance of conflict containment through peace enforcement missions. The rapid growth of globalization and the capability of many nations to provide democratic protections to their populations are again threatened by superpower hegemony and the development of novel unconventional global threats. The survival of the United Nations requires many long overdue organizational structure and governance power reforms, including implementation of a robust United Nations Standing Task Force under Article 43.

Kandra, Prameela; Challa, Murali Mohan; Jyothi, Hemalatha Kalangi Padma

2012-01-01

The production of shrimp waste from shrimp processing industries has undergone a dramatic increase in recent years. Continued production of this biomaterial without corresponding development of utilizing technology has resulted in waste collection, disposal, and pollution problems. Currently used chemical process releases toxic chemicals such as HCl, acetic acid, and NaOH into aquatic ecosystem as byproducts which will spoil the aquatic flora and fauna. Environmental protection regulations have become stricter. Now, there is a need to treat and utilize the waste in most efficient manner. The shrimp waste contains several bioactive compounds such as chitin, pigments, amino acids, and fatty acids. These bioactive compounds have a wide range of applications including medical, therapies, cosmetics, paper, pulp and textile industries, biotechnology, and food applications. This current review article present the utilization of shrimp waste as well as an alternative technology to replace hazardous chemical method that address the future trends in total utilization of shrimp waste for recovery of bioactive compounds.

PUBLIC SUPPORT FOR THE EUROPEAN UNION IN THE CURRENT CONTEXT: PRELIMINARY REMARKS

Directory of Open Access Journals (Sweden)

Iuliana-Lacramioara TINCU

2017-12-01

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

Spin-zero mesons and current algebras

International Nuclear Information System (INIS)

Wellner, M.

1977-01-01

Large chiral algebras, using the f and d coefficients of SU(3) can be constructed with spin-1/2 baryons. Such algebras have been found useful in some previous investigations. This article examines under what conditions similar or identical current algebras may be realized with spin-0 mesons. A curious lack of analogy emerges between meson and baryon currents. Second-class currents, made of mesons, are required in some algebras. If meson and baryon currents are to satisfy the same extended SU(3) algebra, four meson nonets are needed, in terms of which we give an explicit construction for the currents

Toward a more materialistic medicine: the value of authentic materialism within current and future medical practice.

Science.gov (United States)

Leder, Drew; Krucoff, Mitchell W

2011-09-01

Modern medicine is often accused by diverse critics of being "too materialistic" and therefore insufficiently holistic and effective. Yet, this critique can be misleading, dependent upon the ambiguous meanings of "materialism." The term can refer to the prevalence of financial concerns in driving medical practice. Alternatively, it can refer to "mechanistic materialism," the patient viewed as a body-machine. In each case, this article shows that this represents not authentic "materialism" at play, but a focus upon high-level abstractions. "Bottom-line" financial or diagnostic numbers can distract practitioners from the embodied needs of sick patients. In this sense, medical practice is not materialist enough. Through a series of clinical examples, this article explores how an authentic materialism would look in current and future practice. The article examines the use of prayer/comfort shawls at the bedside; hospitals and nursing homes redesigned as enriched healing environments; and a paradigmatic medical device--the implantable cardioverter defibrillator--as it might be presented to patients, in contrast to current practice.

Nadri, Hamed; Rahimi, Bahlol; Timpka, Toomas; Sedghi, Shahram

2017-08-19

The number of citations that a research paper receives can be used as a measure of its scientific impact. The objective of this study was to identify and to examine the characteristics of top 100 cited articles in the field of Medical Informatics based on data acquired from the Thomson Reuters' Web of Science (WOS) in October, 2016. The data was collected using two procedures: first we included articles published in the 24 journals listed in the "Medical Informatics" category; second, we retrieved articles using the key words: "informatics", "medical informatics", "biomedical informatics", "clinical informatics" and "health informatics". After removing duplicate records, articles were ranked by the number of citations they received. When the 100 top cited articles had been identified, we collected the following information for each record: all WOS database citations, year of publication, journal, author names, authors' affiliation, country of origin and topics indexed for each record. Citations for the top 100 articles ranged from 346 to 7875, and citations per year ranged from 11.12 to 525. The majority of articles were published in the 2000s (n=43) and 1990s (n=38). Articles were published across 10 journals, most commonly Statistics in medicine (n=71) and Medical decision making (n=28). The articles had an average of 2.47 authors. Statistics and biostatistics modeling was the most common topic (n=71), followed by artificial intelligence (n=12), and medical errors (n=3), other topics included data mining, diagnosis, bioinformatics, information retrieval, and medical imaging. Our bibliometric analysis illustrated a historical perspective on the progress of scientific research on Medical Informatics. Moreover, the findings of the current study provide an insight on the frequency of citations for top cited articles published in Medical Informatics as well as quality of the works, journals, and the trends steering Medical Informatics.

[Credit problems on scientific article authorships: some solutions].

Casas-Martínez, María de la Luz

2008-01-01

Unfortunately, since the amount of publications has become a parameter for qualifying the scientific production, abuses and even frauds can take place easily. Along with the rising of new investigation projects in which numerous scientists participate, the multi-authorship has also taken place into the scientific scene, with articles having been damaged, modified or altered purposely with erroneous information and plagiarism, against the true author's will. The unconformities among the research team members reflect on a tense and stressful work atmosphere that interferes with investigation process itself; therefore, it is necessary to give and apply more transparency to these activities. The present article will analyze the recommendations from the International Committee of Medical Journal Editors on authorships for medical articles. Here it is pointed out, when an authorship should be considered as one or not, also offering possible solutions to avoid this problem, such as, the elaboration of an author's consent letters written previously to the publication of the article, the elaboration of credits and the limitation of qualified publications regarding each activity reason.

This article reviews current requirements for the analysis for mycotoxins in foods and identifies legislative as well as other factors that are driving development and validation of new methods. New regulatory limits for mycotoxins and analytical quality assurance requirements for laboratories to only use validated methods are seen as major factors driving developments. Three major classes of methods are identified which serve different purposes and can be categorized as screening, official and research. In each case the present status and future needs are assessed. In addition to an overview of trends in analytical methods, some other areas of analytical quality assurance such as participation in proficiency testing and reference materials are identified.

A process is disclosed for producing an article with improved ceramic surface properties including providing an article having a ceramic surface, and placing the article onto a conductive substrate holder in a hermetic enclosure. Thereafter a low pressure ambient is provided in the hermetic enclosure. A plasma including ions of solid materials is produced the ceramic surface of the article being at least partially immersed in a macroparticle free region of the plasma. While the article is immersed in the macroparticle free region, a bias of the substrate holder is biased between a low voltage at which material from the plasma condenses on the surface of the article and a high negative voltage at which ions from the plasma are implanted into the article. 15 figs

Current and Potential Chinese Foreign Direct Investment in the Slovak Republic

Directory of Open Access Journals (Sweden)

Zhang Liqun

2017-06-01

Full Text Available This article presents an overview of current and potential investment from China into the Slovak Republic within the broader CEEC region cooperation based on the 16+1 platform. Based on a business study on the automotive industry in the CEEC region, and particularly Slovakia as one of the industrial sectors for possible Chinese investment with immense potential, the article aims to identify the main advantages and disadvantages of the region as a foreign direct investment destination. The article also analyses the impact of FDI inflows on the Slovak economy. We come to the conclusion that the recent FDI inflow from China to Slovakia has been statistically insignificant, which may, however, change in case the envisaged Chinese investment into the steel industry in Slovakia will be realised. With respect thereto, the article also points at the need to set out a new revised framework for the international legal protection of Chinese investment in the EU. It has been established that further research is required to assess the impact of Chinese FDI on the Slovak economy.

Biography of biophenols: past, present and future

Directory of Open Access Journals (Sweden)

Hassan K. Obied

2013-06-01

Full Text Available ABSTRACTBackground: The term “biophenols” was first coined by Romeo and Uccella in 1996 to denote bioactive phenols in olives replacing the more common and less chemically accurate term “polyphenols”. “Biophenols” has started gaining popularity beyond olive chemistry and currently used by researchers to refer to plant phenols in general. Biophenols constitute the largest group of secondary plant metabolites with ubiquitous presence in plants and wide spectrum of biological activities. During the last three decades, biophenols have seized scientific attention, lured industry and attracted consumers’ interest due to their antioxidative potential in preservation of food and maintaining human health. For the first time, a definition for “biophenols” has been proposed to present a more precise and comprehensive umbrella term to encompass all phenolic compounds of botanical origin. In this article, the author is tracing the landmarks of the history of biophenol research; profiling contemporary research directions; highlighting research controversies and uncertainties; and presenting an outlook of the biophenols future research.Keywords: polyphenols, chemistry, pharmacology, biological activities, antioxidant

Review article: Methodology for the 'rapid review' series on musculoskeletal injuries in the emergency department.

Science.gov (United States)

Strudwick, Kirsten; McPhee, Megan; Bell, Anthony; Martin-Khan, Melinda; Russell, Trevor

2018-02-01

Musculoskeletal injuries are a common presentation to the ED, with significant costs involved in the management of these injuries, variances in care within the ED and associated morbidity. A series of rapid review papers were completed to guide best practice for the assessment and management of common musculoskeletal injuries presenting to the ED. This paper presents the methodology used across the rapid reviews. PubMed, CINAHL, EMBASE, TRIP and the grey literature, including relevant organisational websites, were searched in 2015. The search was repeated consistently for each topic area (injuries of the foot and ankle, knee, hand and wrist, elbow, shoulder, lumbar spine and cervical spine). English-language primary studies, systematic reviews and guidelines that were published in the last 10 years and addressed acute musculoskeletal injury management were considered for inclusion. Data extraction of each included article was conducted, followed by a quality appraisal. The extracted data from each article was synthesised to group similar evidence together. For each rapid review, the evidence has been organised in a way that a clinician can direct their attention to a specific component of the clinical cycle of care in the ED, such as the assessment, diagnostic tests, management and follow-up considerations from ED. The series of rapid reviews are designed to foster evidence-based practice within the ED, targeting the injuries most commonly presenting. The reviews provide clinicians in EDs with rapid access to the best current evidence, which has been synthesised and organised to assist decision-making. © 2017 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

Current issues in onychomycosis.

Science.gov (United States)

Trépanier, E F; Amsden, G W

1998-02-01

To review the epidemiology, mycology, clinical features and diagnosis, current pharmacotherapy, and pharmacoeconomics of onychomycosis. We conducted a MEDLINE search from 1966 to May 1997. References from these articles, manufacturers of the discussed antimycotics, and relevant abstracts from recent dermatology conferences were used to collect pertinent data. Data were obtained from published controlled studies and case reports. In the pharmacotherapy section, the most weight was placed on fully reported, randomized, controlled comparative trials, but abstracts and case series were included when well-controlled studies were unavailable. Onychomycosis is a common nail disorder that has a substantial impact on patients' quality of life. It is most commonly caused by dermatophytes, but yeasts and molds can also be involved. Diagnosis is made through clinical presentation, potassium hydroxide preparations, and culture of tissue/nail samples. Griseofulvin was the drug of choice for many years, but its low cure rates and the development of newer, more effective drugs made it fall out of favor. Current therapeutic alternatives include fluconazole, itraconazole, and terbinafine. Data on the use of fluconazole are limited to case series and reports. Continuous dosing of itraconazole and terbinafine are well-proven therapies. New data are becoming available on the use of pulse itraconazole dosing, which has recently been approved by the Food and Drug Administration for fingernail infections. These drugs are well tolerated, but attention to drug interactions is necessary with the azoles. Currently, continuous terbinafine appears to be the most cost-effective drug for dermatophyte onychomycosis.

du Prel, Jean-Baptist; Röhrig, Bernd; Blettner, Maria

2009-02-01

In the era of evidence-based medicine, one of the most important skills a physician needs is the ability to analyze scientific literature critically. This is necessary to keep medical knowledge up to date and to ensure optimal patient care. The aim of this paper is to present an accessible introduction into critical appraisal of scientific articles. Using a selection of international literature, the reader is introduced to the principles of critical reading of scientific articles in medicine. For the sake of conciseness, detailed description of statistical methods is omitted. Widely accepted principles for critically appraising scientific articles are outlined. Basic knowledge of study design, structuring of an article, the role of different sections, of statistical presentations as well as sources of error and limitation are presented. The reader does not require extensive methodological knowledge. As far as necessary for critical appraisal of scientific articles, differences in research areas like epidemiology, clinical, and basic research are outlined. Further useful references are presented. Basic methodological knowledge is required to select and interpret scientific articles correctly.

How do I write a scientific article?-A personal perspective.

Science.gov (United States)

Lippi, Giuseppe

2017-10-01

Scientific writing is not an easy task. Although there is no single and universally agreed strategy for assembling a successful scientific article, it is undeniable that some basic notions, gathered after decades of experience, may help increasing the chance of acceptance of a scientific manuscript. Therefore, the purpose of this article is to present a personal and arbitrary perspective on how to write a scientific article, entailing a tentative flowchart and a checklist describing the most important aspects characterizing each section of the manuscript. The final suggestion, which can be summarized in one simple and straightforward concept, is that you should always remember that a scientific article is meant to be read by others (i.e., referees and readers) and not by yourself.

Mining biological networks from full-text articles.

Science.gov (United States)

Czarnecki, Jan; Shepherd, Adrian J

2014-01-01

The study of biological networks is playing an increasingly important role in the life sciences. Many different kinds of biological system can be modelled as networks; perhaps the most important examples are protein-protein interaction (PPI) networks, metabolic pathways, gene regulatory networks, and signalling networks. Although much useful information is easily accessible in publicly databases, a lot of extra relevant data lies scattered in numerous published papers. Hence there is a pressing need for automated text-mining methods capable of extracting such information from full-text articles. Here we present practical guidelines for constructing a text-mining pipeline from existing code and software components capable of extracting PPI networks from full-text articles. This approach can be adapted to tackle other types of biological network.

Experiments with eddy currents: the eddy current brake

International Nuclear Information System (INIS)

Gonzalez, Manuel I

2004-01-01

A moderate-cost experimental setup is presented to help students to understand some qualitative and quantitative aspects of eddy currents. The setup operates like an eddy current brake, a device commonly used in heavy vehicles to dissipate kinetic energy by generating eddy currents. A set of simple experiments is proposed to measure eddy current losses and to relate them to various relevant parameters. Typical results for each of the experiments are presented, and comparisons with theoretical predictions are included. The experiments, which are devoted to first-year undergraduate students, deal also with other pedagogically relevant topics in electricity and magnetism, such as basic laws, electrical measurement techniques, the sources of the magnetic field and others

Full Text Available This article presents my reflections on the implementation of one-week-one-article program. Fifty-three students participated in this program. Every week they presented the article they had read. I found that the majority of students actively participated in this program, showing seriousness in understanding the content of the article, the pronunciation of difficult words, and the flow of the presentation. This program at least promoted three aspects: students’ motivation, cooperative learning, and their critical thinking. Even though this program was conducted for university students, it is likely to be working with students of junior and senior secondary school with some modification

Challenges for automatically extracting molecular interactions from full-text articles.

Science.gov (United States)

McIntosh, Tara; Curran, James R

2009-09-24

The increasing availability of full-text biomedical articles will allow more biomedical knowledge to be extracted automatically with greater reliability. However, most Information Retrieval (IR) and Extraction (IE) tools currently process only abstracts. The lack of corpora has limited the development of tools that are capable of exploiting the knowledge in full-text articles. As a result, there has been little investigation into the advantages of full-text document structure, and the challenges developers will face in processing full-text articles. We manually annotated passages from full-text articles that describe interactions summarised in a Molecular Interaction Map (MIM). Our corpus tracks the process of identifying facts to form the MIM summaries and captures any factual dependencies that must be resolved to extract the fact completely. For example, a fact in the results section may require a synonym defined in the introduction. The passages are also annotated with negated and coreference expressions that must be resolved.We describe the guidelines for identifying relevant passages and possible dependencies. The corpus includes 2162 sentences from 78 full-text articles. Our corpus analysis demonstrates the necessity of full-text processing; identifies the article sections where interactions are most commonly stated; and quantifies the proportion of interaction statements requiring coherent dependencies. Further, it allows us to report on the relative importance of identifying synonyms and resolving negated expressions. We also experiment with an oracle sentence retrieval system using the corpus as a gold-standard evaluation set. We introduce the MIM corpus, a unique resource that maps interaction facts in a MIM to annotated passages within full-text articles. It is an invaluable case study providing guidance to developers of biomedical IR and IE systems, and can be used as a gold-standard evaluation set for full-text IR tasks.

Full Text Available Lauren L Levy, Jason J Emer Department of Dermatology, Mount Sinai School of Medicine, New York, NY, USA Abstract: Hair loss is a commonly encountered problem in clinical practice, with men presenting with a distinctive pattern involving hairline recession and vertex balding (Norwood-Hamilton classification and women exhibiting diffuse hair thinning over the crown (increased part width and sparing of the frontal hairline (Ludwig classification. Female pattern hair loss has a strikingly overwhelming psychological effect; thus, successful treatments are necessary. Difficulty lies in successful treatment interventions, as only two medications – minoxidil and finasteride – are approved for the treatment of androgenetic alopecia, and these medications offer mediocre results, lack of a permanent cure, and potential complications. Hair transplantation is the only current successful permanent option, and it requires surgical procedures. Several other medical options, such as antiandrogens (eg, spironolactone, oral contraceptives, cyproterone, flutamide, dutasteride, prostaglandin analogs (eg, bimatoprost, latanoprost, and ketoconazole are reported to be beneficial. Laser and light therapies have also become popular despite the lack of a profound benefit. Management of expectations is crucial, and the aim of therapy, given the current therapeutic options, is to slow or stop disease progression with contentment despite patient expectations of permanent hair regrowth. This article reviews current perspectives on therapeutic options for female pattern hair loss. Keywords: androgenetic alopecia, female pattern hair loss, minoxidil, finasteride, antiandrogens, spironolactone

Iodine in different food articles and standard reference materials

International Nuclear Information System (INIS)

Dermelj, M.; Slejkovec, Z.; Byrne, A.R.; Stegnar, P.; Stibilj, V.; Rossbach, M.

1990-01-01

The greater part of essential iodine enters living organisms via the food chain. Nevertheless, quantitative data on its concentration in diets, food articles and also in available SRMs are very poor and scarce. This and WHO recommendations on daily allowances of iodine for man via food articles caused an added demand for accurate and reliable determination of iodine in these samples. From this point of view the purpose of the present was to analyse and to establish the concentration levels of total iodine in some food articles, diets, SRMs and candidate reference materials by the use of rapid radiochemical separation, developed in our laboratory. The results were checked by the analysis of SRMs with available certified values for iodine and good agreement is evident. (orig.)

Learning to rank figures within a biomedical article.

Full Text Available Hundreds of millions of figures are available in biomedical literature, representing important biomedical experimental evidence. This ever-increasing sheer volume has made it difficult for scientists to effectively and accurately access figures of their interest, the process of which is crucial for validating research facts and for formulating or testing novel research hypotheses. Current figure search applications can't fully meet this challenge as the "bag of figures" assumption doesn't take into account the relationship among figures. In our previous study, hundreds of biomedical researchers have annotated articles in which they serve as corresponding authors. They ranked each figure in their paper based on a figure's importance at their discretion, referred to as "figure ranking". Using this collection of annotated data, we investigated computational approaches to automatically rank figures. We exploited and extended the state-of-the-art listwise learning-to-rank algorithms and developed a new supervised-learning model BioFigRank. The cross-validation results show that BioFigRank yielded the best performance compared with other state-of-the-art computational models, and the greedy feature selection can further boost the ranking performance significantly. Furthermore, we carry out the evaluation by comparing BioFigRank with three-level competitive domain-specific human experts: (1 First Author, (2 Non-Author-In-Domain-Expert who is not the author nor co-author of an article but who works in the same field of the corresponding author of the article, and (3 Non-Author-Out-Domain-Expert who is not the author nor co-author of an article and who may or may not work in the same field of the corresponding author of an article.

Exploring the trends in surgical education research offers insight into concerns, developments, and questions researchers are exploring that are relevant to teaching and learning in surgical specialties. We conducted a review of the surgical education literature published between 2002 and 2012. The purpose was 2-fold: to provide an overview of the most frequently cited articles in the field of surgical education during the last decade and to describe the study designs and themes featured in these articles. Articles were identified through Web of Science by using "surgical education" and "English language" as search terms. Using a feature in Web of Science, we tracked the number of citations of any publication. Of the 800 articles produced by the initial search, we initially selected 23 articles with 45 or more citations, and ultimately chose the 20 articles that were most frequently cited for our analysis. Analysis of the most frequently cited articles published in US journals between the years 2002-2012 identified 7 research themes and presented them in order of frequency with which they appear: use of simulation, issues in student/resident assessment, specialty choice, patient safety, team training, clinical competence assessment, and teaching the clinical sciences, with surgical simulation being the central theme. Researchers primarily used descriptive methods. Popular themes in surgical education research illuminate the information needs of surgical educators as well as topics of high interest to the surgical community.

The Use of Electroconvulsive Therapy in Atypical Psychotic Presentations

Science.gov (United States)

Vasu, Devi

2007-01-01

Convulsive therapy and its progeny, electroconvulsive therapy (ECT), were originally used for the treatment of catatonic schizophrenia, and there is little doubt that ECT remains an effective intervention for the treatment of schizophrenia. However, current practice tends to favor the use of ECT in severe or treatment refractory affective disorders, and its use in schizophrenia and other nonaffective (atypical) psychotic disorders has become controversial. Case reports have suggested a role for ECT in two specific atypical psychotic disorders: Cotard's syndrome and cycloid psychosis. In this article, we review the atypical psychotic disorders and report a series of five case examples that signify the role of ECT in atypical psychotic presentations, particularly when the symptoms resemble those found in Cotard's syndrome and cycloid psychosis.

Method for fabricating boron carbide articles

International Nuclear Information System (INIS)

Ardary, Z.; Reynolds, C.

1980-01-01

Described is a method for fabricating an essentially uniformly dense boron carbide article of a length-to-diameter or width ratio greater than 2 to 1 comprising the steps of providing a plurality of article segments to be joined together to form the article with each of said article segments having a length-to-diameter or width ratio less than 1.5 to 1. Each segment is fabricated by hot pressing a composition consisting of boron carbide powder at a pressure and temperature effective to provide the article segment with a density greater than about 85% of theoretical density, providing each article segment with parallel planar end surfaces, placing a plurality of said article segments in a hot-pressing die in a line with the planar surfaces of adjacent article segments being disposed in intimate contact, and hot pressing the aligned article segments at a temperature and pressure effective to provide said article with a density over the length thereof in the range of about 94 to 98 percent theoretical density and greater than the density provided in the discrete hot pressing of each of the article segments and to provide a bond between adjacent article segments with said bond being at least equivalent in hardness, strength and density to a remainder of said article

Intracranial atherosclerosis: current concepts.

Science.gov (United States)

Arenillas, Juan F

2011-01-01

The most relevant ideas discussed in this article are described here. Intracranial atherosclerotic disease (ICAD) represents the most common cause of ischemic stroke worldwide. Its importance in whites may have been underestimated. New technical developments, such as high-resolution MRI, allow direct assessment of the intracranial atherosclerotic plaque, which may have a profound impact on ICAD diagnosis and therapy in the near future. Early detection of ICAD may allow therapeutic intervention while the disease is still asymptomatic. The Barcelonès Nord and Maresme Asymptomatic Intracranial Atherosclerosis Study is presented here. The main prognostic factors that characterize the patients who are at a higher risk for ICAD recurrence are classified and discussed. The best treatment for ICAD remains to be established. The Stenting Versus Aggressive Medical Management for Preventing Recurrent Stroke in Intracranial Stenosis Study is currently ongoing to address this crucial issue. These and other topics will be discussed at the Fifth International Intracranial Atherosclerosis Conference (Valladolid, Spain, autumn 2011).

Five currents of organizational psychology

2017-01-01

Organizational psychology may be seen as consisting of a number of mutually conflictual currents developed over several decades. This article discusses five currents in organizational psychology that have both been dominant in Scandinavia and have had particular significance in relation...... to the field of organizational development: The social psychological, the socio-technical, the humanistic, the work psychological and the social constructionist currents. Central arguments and works from leading scholars are discussed. It is argued that although treated differently the notions of the small...... group, group dynamics, resistance to change and process consultation constitute pivotal and through going tenets in all the currents. These notions, it is argued, link the discipline of organizational psychology together into a mutually discordant, but anyway relatively consistent research area...

MISO Current-mode Biquad Filter with Independent Control of Pole Frequency and Quality Factor

Directory of Open Access Journals (Sweden)

W. Jaikla

2012-09-01

Full Text Available This article presents a three-inputs single-output biquadratic filter performing completely standard functions: low-pass, high-pass, band-pass, band-reject and all-pass functions, based on current controlled current conveyor transconductance amplifier (CCCCTA. The quality factor and pole frequency can be electronically/independently tuned via the input bias current. The proposed circuit uses 2 CCCCTAs and 2 grounded capacitors without external any resistors which is very suitable to further develop into an integrated circuit. The filter does not require double input current signal. Each function response can be selected by suitably selecting input signals with digital method. Moreover, the circuit possesses high output impedance which would be an ideal choice for current-mode cascading. The PSPICE simulation results are included to verify the workability of the proposed filter. The given results agree well with the theoretical anticipation.

Voting Present

Directory of Open Access Journals (Sweden)

James Lo

2013-12-01

Full Text Available During his time as a state senator in Illinois, Barack Obama voted “Present” 129 times, a deliberate act of nonvoting that subsequently became an important campaign issue during the 2008 presidential elections. In this article, I examine the use of Present votes in the Illinois state senate. I find evidence that Present votes can largely be characterized as protest votes used as a legislative tool by the minority party. Incorporating information from Present votes into a Bayesian polytomous item-response model, I find that this information increases the efficiency of ideal point estimates by approximately 35%. There is little evidence of significant moderation by Obama when Present votes are accounted for, though my results suggest that Obama’s voting record may have moderated significantly before his subsequent election to the U.S. Senate. My results also suggest that because legislative nonvoting may occur for a variety of reasons, naive inclusion of nonvoting behavior into vote choice models may lead to biased results.

Technical Meeting on Impact of Fukushima Event on Current and Future Fast Reactor Designs. Presentations

International Nuclear Information System (INIS)

2012-01-01

The overall purpose of the Technical Meeting was to recognize and analyse the implications of the accident occurred at the Fukushima Dai-ichi Nuclear Power Station on current and future fast neutron systems design and operation. The aim was to provide a global forum for discussing the principal lessons learned from this event, and thus to review safety principles and characteristics of existing and future fast neutron concepts, especially in relation with extreme natural events which potentially may lead to severe accident scenarios. The participants also presented and discussed innovative technical solutions, design features and countermeasures for design extension conditions - including earthquakes, tsunami and other extreme natural hazards - which can enhance the safety level of existing and future fast neutron systems. Furthermore, the meeting gave the opportunity to present advanced methods for the evaluation of the robustness of plants against design extension conditions. Another important goal of this TM was to discuss how to harmonize safety approaches and goals for next generation’s fast reactors. Finally, the meeting was intended to identify areas where further research and development in nuclear safety, technology and engineering in the light of the Fukushima accident are needed. In the frame of the implementation of its Nuclear Safety Action Plan endorsed by all Member States, the IAEA will consider these areas as potential technical topics for new Coordinated Research Projects, to be launched in the near future

Knowledge categorization affects popularity and quality of Wikipedia articles.

Science.gov (United States)

Lerner, Jürgen; Lomi, Alessandro

2018-01-01

The existence of a shared classification system is essential to knowledge production, transfer, and sharing. Studies of knowledge classification, however, rarely consider the fact that knowledge categories exist within hierarchical information systems designed to facilitate knowledge search and discovery. This neglect is problematic whenever information about categorical membership is itself used to evaluate the quality of the items that the category contains. The main objective of this paper is to show that the effects of category membership depend on the position that a category occupies in the hierarchical knowledge classification system of Wikipedia-an open knowledge production and sharing platform taking the form of a freely accessible on-line encyclopedia. Using data on all English-language Wikipedia articles, we examine how the position that a category occupies in the classification hierarchy affects the attention that articles in that category attract from Wikipedia editors, and their evaluation of quality of the Wikipedia articles. Specifically, we show that Wikipedia articles assigned to coarse-grained categories (i. e., categories that occupy higher positions in the hierarchical knowledge classification system) garner more attention from Wikipedia editors (i. e., attract a higher volume of text editing activity), but receive lower evaluations (i. e., they are considered to be of lower quality). The negative relation between attention and quality implied by this result is consistent with current theories of social categorization, but it also goes beyond available results by showing that the effects of categorization on evaluation depend on the position that a category occupies in a hierarchical knowledge classification system.

Outside Mainstream Electronic Databases: Review of Studies Conducted in the USSR and Post-Soviet Countries on Electric Current-Assisted Consolidation of Powder Materials

Directory of Open Access Journals (Sweden)

Eugene G. Grigoryev

2013-09-01

Full Text Available This paper reviews research articles published in the former USSR and post-soviet countries on the consolidation of powder materials using electric current that passes through the powder sample and/or a conductive die-punch set-up. Having been published in Russian, many of the reviewed papers are not included in the mainstream electronic databases of the scientific articles and thus are not known to the scientific community. The present review is aimed at filling this information gap. In the paper, the electric current-assisted sintering techniques based on high- and low-voltage approaches are presented. The main results of the theoretical modeling of the processes of electromagnetic field-assisted consolidation of powder materials are discussed. Sintering experiments and related equipment are described and the major experimental results are analyzed. Sintering conditions required to achieve the desired properties of the sintered materials are provided for selected material systems. Tooling materials used in the electric current-assisted consolidation set-ups are also described.

2018-03-08

Retraction of previously published scientific articles is an important mechanism to preserve the integrity of scientific work. This study analyzed retractions of previously published articles from surgery journals. We searched for retracted articles in the 100 surgery journals with the highest SJR2 indicator grades. We found 130 retracted articles in 49 journals (49%). Five or more retracted articles were published in 8 journals (8%). The mean time between publication and retraction was 26 months (range 1 to 158 months). The United States, China, Germany, Japan, and the United Kingdom accounted for more than 3 out of 4 of the retracted articles. The greatest number of retractions came from manuscripts about orthopedics and traumatology, general surgery, anesthesiology, cardiothoracic surgery, and plastic surgery. Nonsurgeons were responsible for 16% of retractions in these surgery journals. The main reasons for retraction were duplicate publication (42%), plagiarism (16%), absence of proven integrity of the study (14%), incorrect data (13%), data published without authorization (12%), violation of research ethics (11%), documented fraud (11%), request of an author(s) (5%), and unknown (3%). In 25% of the retracted articles, other publications by the same authors also had been retracted. Retraction of published articles does not occur frequently in surgery journals. Some form of scientific misconduct was present in the majority of retractions, especially duplication of publication and plagiarism. Retractions of previously published articles were most frequent from countries with the greatest number of publications; some authors showed recidivism. Copyright © 2018 Elsevier Inc.

Results from the testing of cylinder test article SBKF-P2-CYL-TA02 (referred to herein as TA02) are presented. TA02 is an 8-foot-diameter (96-inches), 78.0-inch-long, aluminum-lithium (Al-Li), orthogrid-stiffened cylindrical shell similar to those used in current state-of-the-art launch-vehicle structures and was designed to exhibit global buckling when subjected to combined compression and bending loads. The testing was conducted at the Marshall Space Flight Center (MSFC), February 3-6, 2009, in support of the Shell Buckling Knockdown Factor Project (SBKF). The test was used to verify the performance of a newly constructed buckling test facility at MSFC and to verify the test article design and analysis approach used by the SBKF researchers.

The Survival of Total Knee Arthroplasty: Current Data from Registries on Tribology: Review Article.

Polyethylene (PE) wear is a major contributor to implant loosening following total knee arthroplasty (TKA), and advanced bearings in TKA are being investigated with hopes of reducing or eliminate wear-related loosening. Currently, information on knee tribology is available from national joint registries and may be the best tools to evaluate the efficacy and safety of design innovations in joint arthroplasty. We performed a review of national joint registries trying to answer the following questions: "Which is the main factor directly related to revisions rate in TKA?" and "Are there new bearing options better than conventional ones?" A review was performed of all published annual reports of National Joint Registers, as well as of the literature. The search was carried out using and comparing the National Joint Registers. Current data from registries for total knee arthroplasty indicates that age is the major factor affecting the outcome of primary total knee replacement. The 10-year cumulative revision rate for non-cross-linked PE was 5.8% and for XLPE it was 3.5%. The effect of cross-linked polyethylene was more evident in the younger patients. The survival of the oxidized zirconium (OxZr) femoral component appears better when compared to a similar age group of patients with conventional group of prostheses. Our review suggests that the revision rates are half for the OxZr components compared to conventional CoCr femoral components. Age is the most relevant single factor related to revision rate. Cross-linked PE has a statistical lower revision rate at 10 years compared to conventional PE and, in the OxZr group, the revision rate is 2 times lower than Co-Cr in the same group of age.

Advances in Psychiatric Diagnosis: Past, Present, and Future

Directory of Open Access Journals (Sweden)

Carol S. North

2017-04-01

Full Text Available This editorial examines controversies identified by the articles in this special issue, which explore psychopathology in the broad history of the classification of selected psychiatric disorders and syndromes over time through current American criteria. Psychiatric diagnosis has a long history of scientific investigation and application, with periods of rapid change, instability, and heated controversy associated with it. The articles in this issue examine the history of psychiatric nomenclature and explore current and future directions in psychiatric diagnosis through the various versions of accepted diagnostic criteria and accompanying research literature addressing the criteria. The articles seek to guide readers in appreciating the complexities of psychiatric diagnosis as the field of psychiatry pushes forward toward future advancements in diagnosis. Despite efforts of many scientists to advance a diagnostic classification system that incorporates neuroscience and genetics, it has been argued that it may be premature to attempt to move to a biologically-based classification system, because psychiatric disorders cannot yet be fully distinguished by any specific biological markers. For now, the symptom-based criteria that the field has been using continue to serve many essential purposes, including selection of the most effective treatment, communication about disease with colleagues, education about psychiatric illness, and support for ongoing research.

Observation of dark pulses in 10 nm thick YBCO nanostrips presenting hysteretic current voltage characteristics

Science.gov (United States)

Ejrnaes, M.; Parlato, L.; Arpaia, R.; Bauch, T.; Lombardi, F.; Cristiano, R.; Tafuri, F.; Pepe, G. P.

2017-12-01

We have fabricated several 10 nm thick and 65 nm wide YBa2Cu3O7-δ (YBCO) nanostrips. The nanostrips with the highest critical current densities are characterized by hysteretic current voltage characteristics (IVCs) with a direct bistable switch from the zero-voltage to the finite voltage state. The presence of hysteretic IVCs allowed the observation of dark pulses due to fluctuations phenomena. The key role of the bistable behavior is its ability to transform a small disturbance (e.g. an intrinsic fluctuation) into a measurable transient signal, i.e. a dark pulse. On the contrary, in devices characterized by lower critical current density values, the IVCs are non-hysteretic and dark pulses have not been observed. To investigate the physical origin of the dark pulses, we have measured the bias current dependence of the dark pulse rate: the observed exponential increase with the bias current is compatible with mechanisms based on thermal activation of magnetic vortices in the nanostrip. We believe that the successful amplification of small fluctuation events into measurable signals in nanostrips of ultrathin YBCO is a milestone for further investigation of YBCO nanostrips for superconducting nanostrip single photon detectors and other quantum detectors for operation at higher temperatures.

Full Text Available Abstract Background Epidemiological and experimental studies have suggested that exposure to particulate air pollution may promote progression of atherosclerosis. Methods In the present study, the characteristics and trends of the research field of particulate matter (PM and atherosclerosis were analyzed using bibliometric indicators. Bibliometric analysis was based on original papers obtained from PubMed/MEDLINE search results (from 1973 to 2014 using Medical Subject Headings (MeSH terms. A fully-detailed search strategy was employed, and articles were imported into the Thomson Data Analyzer (TDA software. Results The visualizing network of the collaborative researchers was analyzed by Ucinet 6 software. Main research topics and future focuses were explored by co-word and cluster analysis. The characteristics of these research articles were summarized. The number of published articles has increased from five for the period 1973–1978 to 89 for the period 2009–2014. Tobacco smoke pollution, smoke and air PM were the most studied targets in this research field. Coronary disease was the top health outcome posed by PM exposure. The aorta and endothelium vascular were the principal locations of atherosclerotic lesions, which were enhanced by PM exposure. Oxidative stress and inflammation were of special concern in the current mechanistic research system. The top high-frequency MeSH terms were clustered, and four popular topics were further presented. Conclusion Based on the quantitative analysis of bibliographic information and MeSH terms, we were able to define the study characteristics and popular topics in the field of PM and atherosclerosis. Our analysis would provide a comprehensive background reference for researchers in this field of study.

Writing business research article abstracts: A genre approach

Directory of Open Access Journals (Sweden)

Carmen Piqué-Noguera

2012-10-01

Full Text Available A great deal has been published about oral and written genres in business (e.g., letters, research articles, oral presentations, etc., and less attention has been paid to business research article abstracts as a written genre, as many experts would argue. This research intends to raise rhetorical awareness about the role of abstracts in today’s academic world. To this effect, the abstracts of two official publications of the Association of Business Communication, Journal of Business Communication and Business Communication Quarterly, have been analyzed and compared in terms of structure and content according to models published in the specialized literature. The results show an irregular and inconsistent presentation of abstracts, a good number of them following no set pattern and thus lacking in important information for researchers. These findings suggest, first of all, that abstracts have a specific mission to fulfil and should not be disregarded; and, secondly, that journal guidelines for authors should be more explicit in their instructions on how to write and structure abstracts.

percentage difference in means was 45% in philosophy, 51% in electrical and electronic engineering, 86% in political science, and 91% in mathematics. Mathematics had the highest rate of open access availability of articles, but political science had the greatest difference in mean citation rates, suggesting there are other, discipline‐specific factors apart from rate of open access uptake affecting research impact. Conclusion – The finding that, across these four disciplines, open access articles have a greater research impact than non‐open access articles, is only one aspect of the complex changes that are presently taking place in scholarly publishing and communication. However, it is useful information for librarians formulating strategies for building institutional repositories, or exploring open access publishing with patrons or publishers.

The History of Liquid Ear Acupuncture and the Current Scientific State of the Art

Measuring the Interestingness of News Articles

Energy Technology Data Exchange (ETDEWEB)

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

2007-09-24

An explosive growth of online news has taken place. Users are inundated with thousands of news articles, only some of which are interesting. A system to filter out uninteresting articles would aid users that need to read and analyze many articles daily, such as financial analysts and government officials. The most obvious approach for reducing the amount of information overload is to learn keywords of interest for a user (Carreira et al., 2004). Although filtering articles based on keywords removes many irrelevant articles, there are still many uninteresting articles that are highly relevant to keyword searches. A relevant article may not be interesting for various reasons, such as the article's age or if it discusses an event that the user has already read about in other articles. Although it has been shown that collaborative filtering can aid in personalized recommendation systems (Wang et al., 2006), a large number of users is needed. In a limited user environment, such as a small group of analysts monitoring news events, collaborative filtering would be ineffective. The definition of what makes an article interesting--or its 'interestingness'--varies from user to user and is continually evolving, calling for adaptable user personalization. Furthermore, due to the nature of news, most articles are uninteresting since many are similar or report events outside the scope of an individual's concerns. There has been much work in news recommendation systems, but none have yet addressed the question of what makes an article interesting.

Rashtak, Shahrooz; Murray, Joseph A

2014-01-01

STRUCTURED SUMMARY Background Celiac disease is managed by life-long gluten withdrawal from the diet. However strict adherence to a gluten-free diet is difficult and is not always effective. Novel therapeutic approaches are needed to supplement or even replace the dietary treatment. Aims To review recent advances in new therapeutic options for celiac disease. Methods A literature search was performed on MEDLINE, EMBASE, Web of Science, Scopus, DDW.org and ClinicalTrial.gov for English articles and abstracts. The search terms used include but not limited to “Celiac disease”, “new”, “novel”, Advances”, “alternatives” and “Drug therapy”. The cited articles were selected based on the relevancy to the review objective. Results Several new therapeutic approaches for celiac disease are currently under development by targeting its underlying pathogenesis. Alternative therapies range from reproduction of harmless wheat strains to immunomodulatory approaches. Some of these therapies such as enzymatic cleavage of gluten and permeability inhibitors have shown promise in clinical studies. Conclusion Gluten-free diet is still the only practical treatment for patients with celiac disease. Novel strategies provide promise of alternative adjunctive approaches to diet restriction alone for patients with this disorder. PMID:22324389

The dynamics of large scale plasma instabilities can be strongly influenced by the mutual interaction with currents flowing in conducting vessel structures. Especially eddy currents caused by time-varying magnetic perturbations and halo currents flowing directly from the plasma into the walls are important. The relevance of a resistive wall model is directly evident for Resistive Wall Modes (RWMs) or Vertical Displacement Events (VDEs). However, also the linear and non-linear properties of most other large-scale instabilities may be influenced significantly by the interaction with currents in conducting structures near the plasma. The understanding of halo currents arising during disruptions and VDEs, which are a serious concern for ITER as they may lead to strong asymmetric forces on vessel structures, could also benefit strongly from these non-linear modeling capabilities. Modeling the plasma dynamics and its interaction with wall currents requires solving the magneto-hydrodynamic (MHD) equations in realistic toroidal X-point geometry consistently coupled with a model for the vacuum region and the resistive conducting structures. With this in mind, the non-linear finite element MHD code JOREK [1, 2] has been coupled [3] with the resistive wall code STARWALL [4], which allows us to include the effects of eddy currents in 3D conducting structures in non-linear MHD simulations. This article summarizes the capabilities of the coupled JOREK-STARWALL system and presents benchmark results as well as first applications to non-linear simulations of RWMs, VDEs, disruptions triggered by massive gas injection, and Quiescent H-Mode. As an outlook, the perspectives for extending the model to halo currents are described

Farič, Nuša; Potts, Henry W W

2014-12-03

Wikipedia is one of the most accessed sources of health information online. The current English-language Wikipedia contains more than 28,000 articles pertaining to health. The aim was to characterize individuals' motivations for contributing to health content on the English-language Wikipedia. A set of health-related articles were randomly selected and recent contributors invited to complete an online questionnaire and follow-up interview (by Skype, by email, or face-to-face). Interviews were transcribed and analyzed using thematic analysis and a realist grounded theory approach. A total of 32 Wikipedians (31 men) completed the questionnaire and 17 were interviewed. Those completing the questionnaire had a mean age of 39 (range 12-59) years; 16 had a postgraduate qualification, 10 had or were currently studying for an undergraduate qualification, 3 had no more than secondary education, and 3 were still in secondary education. In all, 15 were currently working in a health-related field (primarily clinicians). The median period for which they have been an active editing Wikipedia was 3-5 years. Of this group, 12 were in the United States, 6 were in the United Kingdom, 4 were in Canada, and the remainder from another 8 countries. Two-thirds spoke more than 1 language and 90% (29/32) were also active contributors in domains other than health. Wikipedians in this study were identified as health professionals, professionals with specific health interests, students, and individuals with health problems. Based on the interviews, their motivations for editing health-related content were summarized in 5 strongly interrelated categories: education (learning about subjects by editing articles), help (wanting to improve and maintain Wikipedia), responsibility (responsibility, often a professional responsibility, to provide good quality health information to readers), fulfillment (editing Wikipedia as a fun, relaxing, engaging, and rewarding activity), and positive attitude to

Gabriel Louw

2016-12-01

Full Text Available Background The scope of practice of the traditional healer in South Africa is not guided or circumscribed by any statutory mandate at present. The traditional healer’s practice and services are currently based on and driven by the supernatural and the afterlife, lacking not only a scientific foundation, but also legal constraint. Aims This study aimed to determine and describe the present-day scope of practice and services of the South African traditional healer. Methods This is an exploratory and descriptive study that makes use of an historical approach by means of investigation and a literature review. The emphasis is on using current documentation like articles, books and newspapers as primary sources to reflect on the scope of practice and services of the South African traditional healer. The findings are offered in narrative form. Results There is no established curriculum and practice culture to serve as an evaluation and descriptive criteria for the present-day traditional healer’s scope of practice. Conclusion The South African traditional healer’s practice and rights are unwritten and legally unregulated, especially when viewed against in comparison with the current practice customs, traditions and rights of the South African statutorily regulated healthcare practitioners.

[Role of the EFSA in risk management system regarding food contact materials and articles].

Science.gov (United States)

Cwiek-Ludwicka, Kazimiera; Półtorak, Hanna; Pawlicka, Marzena

2009-01-01

The role of the European Food Safety Authority (EFSA) in the risk management system regarding food contact materials and articles is related with the risk assessment of the substances for the European Commission. General rules for the authorisation of substances used in materials and articles intended to contact with food is established in the Regulation (EC) no 1935/2004. For the evaluation of substances their toxicological properties and magnitude of migration into food simulants is taken into account. Toxicological studies include the mutagenicity tests, oral toxicity studies, carcinogenicity, reproduction and also studies on absorption, distribution, metabolism and excretion of the substance and other studies when needed. The set of the relevant toxicological data for substance depends on the magnitude of migration. In the case of positive opinion by EFSA the substance appears on the Community list of authorised substances. Sometimes, the earlier evaluated and authorized substances must undergo re-evaluation due to their new toxicological properties or as a result of a presence in the food of their earlier unknown decomposition products. Examples of the selected substances which underwent re-evaluation by EFSA in the light of the current toxicological knowledge and the relevant activities undertaken by the European Commission have been presented.

O'Sullivan, D; Wilk, S; Michalowski, W; Slowinski, R; Thomas, R; Kadzinski, M; Farion, K

2014-01-01

Online medical knowledge repositories such as MEDLINE and The Cochrane Library are increasingly used by physicians to retrieve articles to aid with clinical decision making. The prevailing approach for organizing retrieved articles is in the form of a rank-ordered list, with the assumption that the higher an article is presented on a list, the more relevant it is. Despite this common list-based organization, it is seldom studied how physicians perceive the association between the relevance of articles and the order in which articles are presented. In this paper we describe a case study that captured physician preferences for 3-element lists of medical articles in order to learn how to organize medical knowledge for decision-making. Comprehensive relevance evaluations were developed to represent 3-element lists of hypothetical articles that may be retrieved from an online medical knowledge source such as MEDLINE or The Cochrane Library. Comprehensive relevance evaluations asses not only an article's relevance for a query, but also whether it has been placed on the correct list position. In other words an article may be relevant and correctly placed on a result list (e.g. the most relevant article appears first in the result list), an article may be relevant for a query but placed on an incorrect list position (e.g. the most relevant article appears second in a result list), or an article may be irrelevant for a query yet still appear in the result list. The relevance evaluations were presented to six senior physicians who were asked to express their preferences for an article's relevance and its position on a list by pairwise comparisons representing different combinations of 3-element lists. The elicited preferences were assessed using a novel GRIP (Generalized Regression with Intensities of Preference) method and represented as an additive value function. Value functions were derived for individual physicians as well as the group of physicians. The results show

Connecting Scientific Articles with Research Data: New Directions in Online Scholarly Publishing

Directory of Open Access Journals (Sweden)

IJsbrand Jan Aalbersberg

2013-05-01

Full Text Available Researchers across disciplines are increasingly utilizing electronic tools to collect, analyze, and organize data. However, when it comes to publishing their work, there are no common, well-established standards on how to make that data available to other researchers. Consequently, data are often not stored in a consistent manner, making it hard or impossible to find data sets associated with an article - even though such data might be essential to reproduce results or to perform further analysis. Data repositories can play an important role in improving this situation, offering increased visibility, domain-specific coordination, and expert knowledge on data management. As a leading STM publisher, Elsevier is actively pursuing opportunities to establish links between the online scholarly article and data repositories. This helps to increase usage and visibility for both articles and data sets and also adds valuable context to the data. These data-linking efforts tie in with other initiatives at Elsevier to enhance the online article in order to connect with current researchers’ workflows and to provide an optimal platform for the communication of science in the digital era.

(Abstract only) The AAVSO is in the process of expanding its education, outreach and speakers bureau program. powerpoint presentations prepared for specific target audiences such as AAVSO members, educators, students, the general public, and Science Olympiad teams, coaches, event supervisors, and state directors will be available online for members to use. The presentations range from specific and general content relating to stellar evolution and variable stars to specific activities for a workshop environment. A presentation—even with a general topic—that works for high school students will not work for educators, Science Olympiad teams, or the general public. Each audience is unique and requires a different approach. The current environment necessitates presentations that are captivating for a younger generation that is embedded in a highly visual and sound-bite world of social media, twitter and U-Tube, and mobile devices. For educators, presentations and workshops for themselves and their students must support the Next Generation Science Standards (NGSS), the Common Core Content Standards, and the Science Technology, Engineering and Mathematics (STEM) initiative. Current best practices for developing relevant and engaging powerpoint presentations to deliver information to a variety of targeted audiences will be presented along with several examples.

Epidemiology: Past, Present, and Future Impacts on Understanding Disease Dynamics and Improving Plant Disease Management-A Summary of Focus Issue Articles.

Ojiambo, P S; Yuen, J; van den Bosch, F; Madden, L V

2017-10-01

Epidemiology has made significant contributions to plant pathology by elucidating the general principles underlying the development of disease epidemics. This has resulted in a greatly improved theoretical and empirical understanding of the dynamics of disease epidemics in time and space, predictions of disease outbreaks or the need for disease control in real-time basis, and tactical and strategic solutions to disease problems. Availability of high-resolution experimental data at multiple temporal and spatial scales has now provided a platform to test and validate theories on the spread of diseases at a wide range of spatial scales ranging from the local to the landscape level. Relatively new approaches in plant disease epidemiology, ranging from network to information theory, coupled with the availability of large-scale datasets and the rapid development of computer technology, are leading to revolutionary thinking about epidemics that can result in considerable improvement of strategic and tactical decision making in the control and management of plant diseases. Methods that were previously restricted to topics such as population biology or evolution are now being employed in epidemiology to enable a better understanding of the forces that drive the development of plant disease epidemics in space and time. This Focus Issue of Phytopathology features research articles that address broad themes in epidemiology including social and political consequences of disease epidemics, decision theory and support, pathogen dispersal and disease spread, disease assessment and pathogen biology and disease resistance. It is important to emphasize that these articles are just a sample of the types of research projects that are relevant to epidemiology. Below, we provide a succinct summary of the articles that are published in this Focus Issue .

Systems and methods for fabricating multi-functional articles comprised of additively formed gradient materials are provided. The fabrication of multi-functional articles using the additive deposition of gradient alloys represents a paradigm shift from the traditional way that metal alloys and metal/metal alloy parts are fabricated. Since a gradient alloy that transitions from one metal to a different metal cannot be fabricated through any conventional metallurgy techniques, the technique presents many applications. Moreover, the embodiments described identify a broad range of properties and applications.

Current simulation of symmetric contacts on CdTe

Ruzin, A.

2011-01-01

This article presents the calculated current-voltage characteristics of symmetric Metal-Semiconductor-Metal configurations for Schottky, Ohmic, and injecting-Ohmic contacts on high resistivity CdTe. The results clearly demonstrate that in the wide band-gap, semi-insulating semiconductors, such as high resistivity CdTe, the linearity of the I-V curves cannot be considered a proof of the ohmicity of the contacts. It is shown that the linear I-V curves are expected for a wide range of contact barriers. Furthermore, the slope of these linear curves is governed by the barrier height, rather than the bulk doping concentration. Therefore the deduction of bulk's resistivity from the I-V curves may be false.

Electron cyclotron heating and current drive: Present experiments to ITER. Revision 1

International Nuclear Information System (INIS)

Harvey, R.W.; Nevins, W.M.; Smith, G.R.; Lloyd, B.; O'Brien, M.R.; Warrick, C.D.

1995-08-01

Electron cyclotron (EC) power has technological and physics advantages for heating and current drive in a tokamak reactor, and advances in source development make it credible for applications in ITER. Strong single pass absorption makes heating to ignition particularly simple. The optimized EC current drive (ECCD) efficiency (left-angle n right-angle IR/P) shows a linear temperature scaling at temperatures up to ∼ 15 keV. For temperatures above 30 keV, the efficiency saturates at approximately 0.3·10 20 A/(m 2 W) for a frequency of 220 GHz in an ITER target plasma with toroidal field of 6 T, due primarily to harmonic overlap [G.R. Smith et al., Phys. Fluids 30 3633 (1987)] and to a lesser extent due to limitations arising from relativistic effects [N.J. Fisch, Phys. Rev. A 24 3245 (1981)]. The same efficiency can also be obtained at 170 GHz for the same plasma equilibrium except that the magnetic field is reduced to (170/220) x 6 T = 4.6 T. The ECCD efficiencies are obtained with the comprehensive 3D, bounce-averaged Fokker-Planck CQL3D codes [R.W. Harvey and M.G. McCoy, Proc. IAEA TCM/Advances in Simulation and Modeling in Thermonuclear Plasmas 1992, Montreal], and BANDIT3D [M.R. O'Brien, M. Cox, C.D. Warrick, and F. S. Zaitsev, ibid.

The article provides a summary of the epidemiologic and clinical aspects of testicular malignancy. Current standard imaging and novel techniques are reviewed. Present data and clinical treatment trends have favored surveillance protocols over adjuvant radiation or chemotherapy for low-stage testicular malignancy. This has resulted in increasing numbers of imaging studies and the potential for increased long-term exposure risks. Understanding imaging associated risks as well as strategies to minimize these risks is of increasing importance. The development, validation and incorporation of alternative lower risk highly efficacious and cost-effective imaging techniques is essential.

Marco Toledo Bastos

2013-09-01

Full Text Available In this article we investigate the impact of social media readership to the editorial profile of newspapers. We analyze tweets containing links to news articles from eight of the largest national newspapers in the United States, United Kingdom, Spain, Brazil, and Germany. The data collection follows the first two weeks of October 2012 and includes 2,842,699 tweets with links to news articles. Twitter-shortened links were resolved using a three-pass routine and assigned to 1 of the 21 newspaper sections. We found the concentration of links to news articles posted by top users to be lower than reported in the literature and the strategy of relaying headlines on Twitter via automatic news aggregators (feeds to be inefficient. The results of this investigation show which sections of a newspaper are the most and least read by readers in different parts of the world, with German readers placing greater emphasis on Politics and Economy; Brazilians on Sports and Arts; Spaniards on Local and National news; Britons and Americans on Opinion and World news. We also found that German and Spanish readers are more likely to read multiple national newspapers, while British readers more often resort to foreign sources of news. The results confirm that feedback to news items from a large user base is pivotal for the replication of content and that newspapers and news items can be clustered according to the editorial profile and principles of newsworthiness inherited from legacy media. The results of this investigation shed light onto the networked architecture of journalism that increasingly depends on readership agency.

Fire prevention in industrial installations presenting a risk for man and environment (ICPE)

Moche, L.

2000-01-01

The most likely accident in industrial installations is fire. 59 out of 100 accidents reported in 1999 describe a fire outbreak, the fire is either the initiating cause of the accident or the form into which the event eventually evolves. This article briefly describes the why and the wherefore of French regulations on fire prevention in installations presenting a risk for man and environment. The French system is based on the responsibility of the plant operator and on the result of inspections performed by authorities to check the conformity of the installation with current regulations.

Dense ceramic articles

International Nuclear Information System (INIS)

Cockbain, A.G.

1976-01-01

A method is described for the manufacture of articles of substantially pure dense ceramic materials, for use in severe environments. Si N is very suitable for use in such environments, but suffers from the disadvantage that it is not amenable to sintering. Some disadvantages of the methods normally used for making articles of Si N are mentioned. The method described comprises mixing a powder of the substantially pure ceramic material with an additive that promotes densification, and which is capable of nuclear transmutation into a gas when exposed to radiation, and hot pressing the mixture to form a billet. The billet is then irradiated to convert the additive into a gas which is held captive in the billet, and it is then subjected to a hot forging operation, during which the captive gas escapes and an article of substantially pure dense ceramic material is forged. The method is intended primarily for use for Si N, but may be applied to other ceramic materials. The additive may be Li or Be or their compounds, to the extent of at least 5 ppm and not more than 5% by weight. Irradiation is effected by proton or neutron bombardment. (UK)

Objective: This report summarizes data on traditional and nontraditional manifestations of primary hyperparathyroidism (PHPT) that have been published since the last International Workshop on PHPT. Participants: This subgroup was constituted by the Steering Committee to address key questions related to the presentation of PHPT. Consensus was established at a closed meeting of the Expert Panel that followed. Evidence: Data from the 5-year period between 2008 and 2013 were presented and discussed to determine whether they support changes in recommendations for surgery or nonsurgical follow-up. Consensus Process: Questions were developed by the International Task Force on PHPT. A comprehensive literature search for relevant studies was undertaken. After extensive review and discussion, the subgroup came to agreement on what changes in the recommendations for surgery or nonsurgical follow-up of asymptomatic PHPT should be made to the Expert Panel. Conclusions: 1) There are limited new data available on the natural history of asymptomatic PHPT. Although recognition of normocalcemic PHPT (normal serum calcium with elevated PTH concentrations; no secondary cause for hyperparathyroidism) is increasing, data on the clinical presentation and natural history of this phenotype are limited. 2) Although there are geographic differences in the predominant phenotypes of PHPT (symptomatic, asymptomatic, normocalcemic), they do not justify geography-specific management guidelines. 3) Recent data using newer, higher resolution imaging and analytic methods have revealed that in asymptomatic PHPT, both trabecular bone and cortical bone are affected. 4) Clinically silent nephrolithiasis and nephrocalcinosis can be detected by renal imaging and should be listed as a new criterion for surgery. 5) Current data do not support a cardiovascular evaluation or surgery for the purpose of improving cardiovascular markers, anatomical or functional abnormalities. 6) Some patients with mild PHPT

In contrast to past centuries, scientific researchers have been currently conducted systematically in all countries as part of an education strategy. As a consequence, scientists have published thousands of reports. Writing an effective article is generally a significant problem for researchers. All parts of an article, specifically the abstract, material and methods, results, discussion and references sections should contain certain features that should always be considered before sending a manuscript to a journal for publication. It is generally known that the material and methods section is a relatively easy section of an article to write. Therefore, it is often a good idea to begin by writing the materials and methods section, which is also a crucial part of an article. Because "reproducible results" are very important in science, a detailed account of the study should be given in this section. If the authors provide sufficient detail, other scientists can repeat their experiments to verify their findings. It is generally recommended that the materials and methods should be written in the past tense, either in active or passive voice. In this section, ethical approval, study dates, number of subjects, groups, evaluation criteria, exclusion criteria and statistical methods should be described sequentially. It should be noted that a well-written materials and methods section markedly enhances the chances of an article being published.

Preliminary determination of the energy potential of ocean currents along the southern coast of Brazil

The ocean can be a strategic alternative for obtaining energy supplies, both from ocean waves as from sea currents and tides. Among these features, the power generation projects based on ocean currents are still under development. Generating energy from ocean can have great impact on the Brazilian energy grid, since Brazil has a vast coastline, with more than 9,000 km long, with potential for generating energy from ocean currents not fully estimated. This article presents a preliminary determination of the energy potential for power generation from ocean currents along the coast of Rio Grande do Sul, the southernmost state of Brazil, and also presents notes that contribute to the characterization of the system of ocean currents in the region. The data used were obtained in two areas near Tramandai, allowing the determination of velocities and directions of the currents on a seasonal basis. The maximum speeds obtained rarely exceed 0.750 m/s, while the average speeds do not exceed 0.200 m/s. A relationship with the prevailing winds in the region was identified. Unfortunately, the results do not allow optimism about the power generation from ocean currents on the southern coast of Brazil, at least over the continental shelf.

In the past two decades enormously scientific researches on posttraumatic stress disorder (PTSD) have been undertaken and many related meta-analyses have been published. Citation analysis was used to get comprehensive perspectives of meta-analysis articles (MA articles) on PTSD for the purpose of facilitating the researchers, physicians and policy-makers to understand the PTSD. MA articles on PTSD in any languages from January 1980 to March 2009 were included if they presented meta-analytical methods and received at least one citation recorded in the Web of Science (WoS). Whereas studies, in which any effect sizes of PTSD were not distinguished from other psychological disorders, were excluded. Citations to and by identified MA articles were documented basing on records in WoS. Citation analysis was used to examine distribution patterns of characteristics and citation impact of MA articles on PTSD. Canonical analysis was used to explore the relationship between the characteristics of MA articles and citation impact. Thirty-four MA articles published during 1998 and 2008 were identified and revealed multiple study topics on PTSD: 10 (29.4%) were about epidemiology, 13 (38.2%) about treatment or intervention, 6 (17.6%) about pathophysiology or neurophysiology or neuroendocrine, 3 (8.8%) about childhood and 2 (5.9%) about psychosocial adversity. Two articles cited most frequently with 456 and 145 counts were published in Journal of Consulting and Clinical Psychology by Brewin (2000) and Psychological Bulletin by Ozer (2003), respectively. Mean cited count was 7.48 ± 10.56 and mean age (year 2009 minus article publication year) was (4.24 ± 2.91) years. They had been cited approximately by 67 disciplines and by authors from 42 countries or territories. Characteristics of meta-analysis highly correlated with citation impact and reflected by canonical correlation of 0.899 (P < 0.000 01). The age of MA articles predicted their citation impact. Citation analysis would

Measuring the Interestingness of Articles in a Limited User Environment

Energy Technology Data Exchange (ETDEWEB)

Pon, Raymond K. [Univ. of California, Los Angeles, CA (United States)

2008-01-01

Search engines, such as Google, assign scores to news articles based on their relevancy to a query. However, not all relevant articles for the query may be interesting to a user. For example, if the article is old or yields little new information, the article would be uninteresting. Relevancy scores do not take into account what makes an article interesting, which varies from user to user. Although methods such as collaborative filtering have been shown to be effective in recommendation systems, in a limited user environment, there are not enough users that would make collaborative filtering effective. A general framework, called iScore, is presented for defining and measuring the 'interestingness' of articles, incorporating user-feedback. iScore addresses various aspects of what makes an article interesting, such as topic relevancy, uniqueness, freshness, source reputation, and writing style. It employs various methods to measure these features and uses a classifier operating on these features to recommend articles. The basic iScore configuration is shown to improve recommendation results by as much as 20%. In addition to the basic iScore features, additional features are presented to address the deficiencies of existing feature extractors, such as one that tracks multiple topics, called MTT, and a version of the Rocchio algorithm that learns its parameters online as it processes documents, called eRocchio. The inclusion of both MTT and eRocchio into iScore is shown to improve iScore recommendation results by as much as 3.1% and 5.6%, respectively. Additionally, in TREC11 Adaptive Filter Task, eRocchio is shown to be 10% better than the best filter in the last run of the task. In addition to these two major topic relevancy measures, other features are also introduced that employ language models, phrases, clustering, and changes in topics to improve recommendation results. These additional features are shown to improve recommendation results by iScore by

Examination of top-cited articles is a tool that can help to identify and monitor outstanding scientific researches and landmark papers. We aimed to identify the 100 most cited published papers in peer-reviewed biomedical journals in the field of digestive diseases and to examine their characteristics. The Web of Science (including Science Citation Index) was searched for the most cited papers related to digestive diseases, published from 1955 to the present. The top 100 most cited articles were identified. The number of citations, countries, and institutions of origin, year of publication, study design, topic, and levels of evidence of the articles were noted and analyzed. The most top-cited articles had a mean of 1375 citations. These articles were published between 1978 and 2009 in 29 high-impact journals, with the New England Journal of Medicine (n = 22) topping the list. Of the 100 articles, 34 were clinical studies, 15 were review articles, and 34 were concerned basic science. These articles came from 18 countries, with the USA contributing most of the top-cited articles (n = 53). Eighty-seven institutions produced these 100 top-cited articles, led by the University of Barcelona (n = 4). Seven persons authored two or more of these top-cited articles. The mostly represented specialty was gastrointestinal oncology (n = 49). Our study can give a historical perspective on the scientific progress of digestive diseases, as well as allow for recognition of most important advances in this area and provide useful information to guide future researches. © 2015 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

Full Text Available Postoperative delirium (POD represents an acute brain dysfunction in the postsurgical period. Perioperative physicians caring for the older adults are familiar with the care of dysfunction of organs such as lungs, heart, liver, or kidney in the perioperative setting, but they are less familiar with management of brain dysfunction. As early detection and prompt treatment of inciting factors are utmost important to prevent or minimize the deleterious outcomes of delirium. The purpose of this review is to prepare perioperative physicians with a set of current clinical practice recommendations to provide optimal perioperative care of older adults, with a special focus on specific perioperative interventions that have been shown to prevent POD. On literature search in EMBASE, CINAHL, and PUBMED between January 2000 and September 2015 using search words delirium, POD, acute postoperative confusion, and brain dysfunction resulted in 9710 articles. Among them, 73 articles were chosen for review, in addition, National Institute for Health and Clinical Excellence guidelines, American Geriatric Society guidelines, hospital elderly life program-confusion assessment method training manual, New York geriatric nursing protocols, World Health Organization's International Classification of Diseases, 10th Revision classification of mental disorders, Food and Drug Administration requests boxed warnings on older class of antipsychotic drugs 2008 and delirium in Miller's text book of anesthesia were reviewed and relevant information presented in this article.

Dental prostheses mimic the natural enamel behavior under functional loading: A review article

Directory of Open Access Journals (Sweden)

Ahmed A. Madfa

2016-02-01

Full Text Available Alumina- and zirconia-based ceramic dental restorations are designed to repair functionality as well as esthetics of the failed teeth. However, these materials exhibited several performance deficiencies such as fracture, poor esthetic properties of ceramic cores (particularly zirconia cores, and difficulty in accomplishing a strong ceramic–resin-based cement bond. Therefore, improving the mechanical properties of these ceramic materials is of great interest in a wide range of disciplines. Consequently, spatial gradients in surface composition and structure can improve the mechanical integrity of ceramic dental restorations. Thus, this article reviews the current status of the functionally graded dental prostheses inspired by the dentino-enamel junction (DEJ structures and the linear gradation in Young's modulus of the DEJ, as a new material design approach, to improve the performance compared to traditional dental prostheses. This is a remarkable example of nature's ability to engineer functionally graded dental prostheses. The current article opens a new avenue for recent researches aimed at the further development of new ceramic dental restorations for improving their clinical durability.

How Dentists Read a Technique Article: A Grounded Theory Investigation.

Science.gov (United States)

Chambers, David W; Lyon, Lucinda J

2017-12-01

To conduct an empirical investigation using qualitative techniques of the way dentists engage in the process of reading a technique-oriented journal article and what they pay attention to in the process. Grounded theory was used to identify how dentists read an article describing the fabrication of an interim prosthesis in the esthetic zone. Twenty-one experienced practitioners were videotaped, and their verbatim reflections were coded. The sequence of attending to various features of the paper was noted. Ninety-five percent of readers voiced specific, multiple attempts to identify or refine the main purpose of the article as they processed the material. All readers engaged in various activities to navigate through the article, including skipping and backtracking, and none "read" the article straight through. All readers also made repeated observations about the relevance of the technique to their personal practice situation. Eighty percent used some form of "distancing," whereby the content and value of the article were accepted, but the reader reserved the privilege of not being bound by the results because of technical, sponsorship, or methodological issues that "might be present." The quality of photographs was accepted as a proxy for the quality of technical work performed. Dentists actively customized the reading of a journal article that described a technical procedure. They imposed a non-linear structure for absorbing information and a standard of personal relevance, and, while accepting the results, created reasons for not necessarily having to accept them as applicable. The approach clinicians use in reading a procedural article may be different from the structure writers use in preparing a paper. © 2016 by the American College of Prosthodontists.

Design guidelines for adapting scientific research articles: An example from an introductory level, interdisciplinary program on soft matter

Science.gov (United States)

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

2013-01-01

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

It is now almost 15 years since the publication of the first paper on text mining in the genomics domain, and decades since the first paper on text mining in the medical domain. Enormous progress has been made in the areas of information retrieval, evaluation methodologies and resource construction. Some problems, such as abbreviation-handling, can essentially be considered solved problems, and others, such as identification of gene mentions in text, seem likely to be solved soon. However, a number of problems at the frontiers of biomedical text mining continue to present interesting challenges and opportunities for great improvements and interesting research. In this article we review the current state of the art in biomedical text mining or ‘BioNLP’ in general, focusing primarily on papers published within the past year. PMID:17977867

Invited Review Article: Measurements of the Newtonian constant of gravitation, G.

Science.gov (United States)

Rothleitner, C; Schlamminger, S

2017-11-01

By many accounts, the Newtonian constant of gravitation G is the fundamental constant that is most difficult to measure accurately. Over the past three decades, more than a dozen precision measurements of this constant have been performed. However, the scatter of the data points is much larger than the uncertainties assigned to each individual measurement, yielding a Birge ratio of about five. Today, G is known with a relative standard uncertainty of 4.7 × 10 -5 , which is several orders of magnitudes greater than the relative uncertainties of other fundamental constants. In this article, various methods to measure G are discussed. A large array of different instruments ranging from the simple torsion balance to the sophisticated atom interferometer can be used to determine G. Some instruments, such as the torsion balance can be used in several different ways. In this article, the advantages and disadvantages of different instruments as well as different methods are discussed. A narrative arc from the historical beginnings of the different methods to their modern implementation is given. Finally, the article ends with a brief overview of the current state of the art and an outlook.

On the article by Henri Poincare' open-quotes on the dynamics of the electronclose quotes

International Nuclear Information System (INIS)

Logunov, A.A.

1996-01-01

The first complete translations into English are presented of two articles written by the outstanding French scientist Henri Poincare and submitted by him in 1905 under the common title of open-quotes Sur la dynamique de l'electronclose quotes to different journals. In the present edition of these articles by H. Poincare, modern notation is used, and the articles are accompanied by comments written by A.A. Logunov. The author of the comments explains the profound physical meaning and essential novelty of the particular points and relationships established by Poincare. Such explanations are often interspersed with quotations from earlier articles by Poincare, thus clearly indicating that the main initial points of the new theory were put forward by the French scientist much before 1905, while certain concepts like 'local' time and the arbitrariness of simultaneity were given a clear explanation from the point of view of physical meaning. A.A. Logunov's book, presenting the works of Poincare on the development of relativity theory, has had quite a high success among specialists interested in the history of physics, and since 1984 it has been published in Russian three times. The present English-language edition is identical to the last 1988 Russian edition, and is dedicated to the 90th anniversary of Poincare's articles 'On the Dynamics of the Electron'. In preparing the English text, fragments were used of the translation of the long article by H.Poincare published in the book by Professor C.W. Kilmister from King's College in London/Special Theory of Relativity, Pergamon Press, New York, 1970/

Near-Earth Magnetic Field Effects of Large-Scale Magnetospheric Currents

Luehr, Hermann; Xiong, Chao; Olsen, Nils; Le, Guan

2016-01-01

Magnetospheric currents play an important role in the electrodynamics of near- Earth space. This has been the topic of many space science studies. Here we focus on the magnetic fields they cause close to Earth. Their contribution to the geomagnetic field is the second largest after the core field. Significant progress in interpreting the magnetic fields from the different sources has been achieved thanks to magnetic satellite missions like Ørsted, CHAMP and now Swarm. Of particular interest for this article is a proper representation of the magnetospheric ring current effect. Uncertainties in modelling its effect still produce the largest residuals between observations and present-day geomagnetic field models. A lot of progress has been achieved so far, but there are still open issues like the characteristics of the partial ring current. Other currents discussed are those flowing in the magnetospheric tail. Also their magnetic contribution at LEO orbits is non-negligible. Treating them as an independent source is a more recent development, which has cured some of the problems in geomagnetic field modelling. Unfortunately there is no index available for characterizing the tail current intensity. Here we propose an approach that may help to properly quantify the magnetic contribution from the tail current for geomagnetic field modelling. Some open questions that require further investigation are mentioned at the end.

Writing papers can be used as a means to convey a message. Knowledge transfer is also about conveying the right message to the right target audience. The aim of this study was to determine the proportion of articles that had mentioned a clear message and the target audience in the abstract and the article as a whole, and also to examine their association with different determinant factors. Articles published from 2001 to 2006 that were based on clinical and health system research conducted on Iranian populations and on maternal care, diabetes and tuberculosis were searched systematically in domestic and international databases. Eventually checklists (Additional file 1) were completed for 795 articles. Overall, 98.5% of articles had a clear message, whereas 12.5% had addressed the direct target audience. Presence of a clear message in formatted abstracts were seen 3.6 times more (CI95%: 1.5-8.7) than in articles without formatted abstracts (p = 0.005). Addressing of the direct target audience was seen twice as much in health system research articles as compared to clinical studies, odds ratio was 2.3 (CI95%: 1.47-3.48, p<0.001). Creating a format for journal abstracts seems to be an effective intervention for presenting the message in articles.

Method of producing silicon carbide articles

International Nuclear Information System (INIS)

Milewski, J.V.

1985-01-01

A method of producing articles comprising reaction-bonded silicon carbide (SiC) and graphite (and/or carbon) is given. The process converts the graphite (and/or carbon) in situ to SiC, thus providing the capability of economically obtaining articles made up wholly or partially of SiC having any size and shape in which graphite (and/or carbon) can be found or made. When the produced articles are made of an inner graphite (and/or carbon) substrate to which SiC is reaction bonded, these articles distinguish SiC-coated graphite articles found in the prior art by the feature of a strong bond having a gradual (as opposed to a sharply defined) interface which extends over a distance of mils. A method for forming SiC whisker-reinforced ceramic matrices is also given. The whisker-reinforced articles comprise SiC whiskers which substantially retain their structural integrity

Shared Responsibility under Article 80 CISG

DEFF Research Database (Denmark)

Neumann, Thomas

2009-01-01

Article 80 exempts from liability in the situation where the promisor's failure to perform has been caused by the promisee. The Article has been insufficiently dealt with in the literature and has been overlooked in case law. The paper demonstrates that article 80 has an independent scope compared...... to articles 77, 79 and 80. Five areas are investigated in this regard; the placement in CISG, the focus of the Articles, the cause of the detriment or loss, the affected remedies and the duty to overcome the detriment or loss. Further more, the paper outlines the issues related to the particular situation...... of shared responsibility in which both the promisor and the promisee seem to have caused the promisor's failure to perform. Article 80 applies to three different case types. Firstly, cases of sole causation by the promisee. Secondly, cases of joint causation by both parties where the consequences of each...

Editorial: Journal article reporting standards.

Science.gov (United States)

Kazak, Anne E

2018-01-01

In this editorial, the author notes that this issue of American Psychologist features a pair of important articles related to newly updated standards for reporting research in psychology in scientific journals, covering both quantitative (Appelbaum et al., 2018) and qualitative (Levitt et al., 2018) research. The increasing breadth and complexity of research, and the importance of communicating it effectively, requires user-friendly resources that can be applied widely to scientific studies. These two articles are intended to serve that purpose, and to encourage thoroughness and accuracy in research reporting, for psychologists and other scientists in broader academic communities. The articles, known as the Journal Article Reporting Standards (JARS) reports, are based on the work of a task force appointed by the American Psychological Association (APA) Publications and Communications Board in 2015.

Predictors of article impact in suicidology: the bereavement literature, a research note.

Science.gov (United States)

Andriessen, Karl; Krysinska, Karolina; Stack, Steven

2015-02-01

Citation analysis has been neglected in suicidology. The present note applies a mixed-methods approach to both test and suggest hypotheses for the variation in article impact in the bereavement literature. One hundred three articles from three core suicidology journals met the criteria for inclusion in the investigation. Citations to the articles were obtained from the Web of Science. Predictor variables included structural characteristics of the author (e.g., gender) and the article itself (e.g., years since publication). A multivariate regression analysis determined that, controlling for the other variables, the most important predictor of citations was the review article (β = .461), followed by year of publication (β = -.414), the multiauthored article (β = .302), publication in Suicide and Life-Threatening Behavior (SLTB) (β = .161), and male gender (β = .156). The 12 most cited articles were published between 1979 and 2004 in SLTB. The majority of these papers was written by males, were U.S. authors, and had more than one author. Four of the most cited articles were reviews. The study concludes that structural characteristics of articles and authors explained 41% of the variance in citations. The qualitative analysis determined that review papers, and papers on characteristics of suicide bereavement and psychological autopsies have been most frequently cited. Replication studies are needed for other subfields of suicidology. © 2014 The American Association of Suicidology.

Shifting Global Climate Governance: Creating Long-Term Goals Through UNFCCC Article 2

Directory of Open Access Journals (Sweden)

P. Brian Fisher

2011-12-01

Full Text Available I argue that the long-term risk of global climate change has been mischaracterized as an environmental issue, and therefore, solutions based solely on national emission targets will be ineffective. Thus, this paper argues for establishing long-term goals emphasizing both adaptation and clean energy to generate equitable and effective global climate policy that addresses this fundamental threat. This requires defining and operationalizing the overall objective contained in Article 2 of the United Nations Framework Convention on Climate Change. A second key aspect to operationalizing Article 2 is to understand those ‘particularly vulnerable’ as declared in the Article and in various climate agreements. Once operationalized, these long-term objectives can be achieved through approaches that emphasize the development of clean energy (and concomitant technology, and adaptation within vulnerable communities in their local context. It necessitates dropping formal mechanisms at the current core of the regime designed to regulate national emissions, and instead build the core of the regime around the ‘stabilization’ of both the climate system through clean energy and vulnerable people through effective adaptation.
