2017-11-01

This article presents the results obtained from monitoring a VAV system with highly diversified zone occupancy density are presented in the article. The investigated VAV system meets the load for 72 zones (68 perimeters and 4 interiors) consisting of classrooms, offices, conference rooms, etc. with highly diversified occupancy densities from 1.875 to 2.5 m2/person for the classrooms and from 10 to 15 m2/person for the offices. The monitoring shows that the CO2 concentration can exceed the set point in the critical rooms. Simulation results are also presented in the article to show that it is often impossible to adjust the operation of such VAV systems because the adjusted System Outdoor Air Fractions, % OA, can reach 100% even where the zone CO2 concentration is not respected. The presented monitoring and simulation results were obtained in the winter, with the VAV system operating at partial load and with the minimum outdoor air flowrate required by the economizer system. As shown in the article, to respect the zone set point CO2 concentration in such period, the VAV system must operate mostly at a %OA equal to 100% instead of its minimum value. To circumvent this, the supply zone air flow rate may have to be designed taking into account the CO2 concentration resulting from the critical zones occupancy density.

This paper presents a bibliographic analysis of Nature articles based on altmetrics. We assess the concern degree of social users on the Nature articles through the coverage analysis of Twitter and Facebook by publication year and discipline. The social media impact of a Nature article is examined by evaluating the mention rates on Twitter and on Facebook. Moreover, the correlation between tweets and citations is analyzed by publication year, discipline and Twitter user type to explore factors affecting the correlation. The results show that Twitter users have a higher concern degree on Nature articles than Facebook users, and Nature articles have higher and faster-growing impact on Twitter than on Facebook. The results also show that tweets and citations are somewhat related, and they mostly measure different types of impact. In addition, the correlation between tweets and citations highly depends on publication year, discipline and Twitter user type. PMID:27906981

The concept of being at risk for psychosis has been introduced both for adults and children and adolescents, but fewer studies have been conducted in the latter population. The aim of this study is to systematically review the articles associated with clinical description, interventions, outcome and other areas in children and adolescents at risk for psychosis. We searched in MEDLINE/PubMed and PsycINFO databases for articles published up to 30/06/16. Reviewed articles were prospective studies; written in English; original articles with Clinical High Risk (CHR) for psychosis samples; and mean age of samples younger than 18 years. From 103 studies initially selected, 48 met inclusion criteria and were systematically reviewed. Studies show that CHR children and adolescents present several clinical characteristics at baseline, with most attenuated positive-symptom inclusion criteria observed, reporting mostly perceptual abnormalities and suspiciousness, and presenting comorbid conditions such as depressive and anxiety disorders. CHR children and adolescents show lower general intelligence and no structural brain changes compared with controls. Original articles reviewed show rates of conversion to psychosis between 17 and 20% at 1 year follow-up and between 7 and 21% at 2 years. While 36% of patients recovered from their CHR status at 6-year follow-up, 40% still met CHR criteria. Studies in children and adolescents with CHR were conducted with different methodologies, assessments tools and small samples. It is important to conduct studies on psychopharmacological and psychological treatment, as well as replication of the few studies found.

The aim of this study was to evaluate the publication rates of full-text articles after presentation of abstracts at a Turkish National Orthopaedics and Traumatology Congress, determine the time lag from the congress date to publication of full-text articles and assess the consistency between abstracts and the subsequent publications. All abstracts from the scientific program of the 20th Turkish National Orthopaedics and Traumatology Congress (2007) were identified and computerized PubMed searches were conducted to determine whether an abstract had been followed by publication of a full-text article and key features were compared to evaluate their consistency. The time lag to publication and the impact factors of the journals where the articles were published were noted. Of the 770 abstracts (264 oral, 506 poster presentations), 227 (29.5%) were followed by a full-text and 116 (44%) of the 264 oral and 111 (22%) of the 506 poster presentations were published. The mean time to publication was 14.9±16.075 (range: 33 to 55) months. Thirty-three (14.5%) were published prior to the presentation at the congress. The likelihood of publication decreased after the third year (26 of 227, 11.5%). A total of 182 (80.2%) articles showed inconsistencies with the abstract; 74 (32.6%) minor, 14 (6.2%) major, and 94 (41.4%) minor and major inconsistencies. The mean impact factor of the journals was 1.152±0.858. The vast majority of abstracts presented at this congress were not followed by publication of a full-text article. Additionally, frequent inconsistencies between the final published article and the original abstract indicated the inadequacy of quality of reporting in abstracts.

"Shades of Foreign Evil": "Honor Killings" and "Family Murders" in the Canadian Press.

This article compares murder cases labeled "honor killings" with cases labeled "family/spousal murders" in the Canadian news media, exploring the construction of boundaries between these two practices. We conducted a systematic qualitative content analysis, examining a sample of 486 articles from three major Canadian newspapers between 2000 and 2012. Our analysis shows that "honor killings" are framed in terms of culture and ethnic background, presenting a dichotomy between South Asian/Muslim and Western values. Conversely, articles presenting cases as "family/spousal murders" tend to focus on the perpetrators' personalities or psychological characteristics, often ignoring factors such as culture, patriarchy, honor, and shame. © The Author(s) 2015.

The data presented in this article are related to the article titled "Molecular Dynamics as a tool for in silico screening of skin permeability" (Rocco et al., 2017) [1]. Knowledge of the confidence interval and maximum theoretical value of the correlation coefficient r can prove useful to estimate the reliability of developed predictive models, in particular when there is great variability in compiled experimental datasets. In this Data in Brief article, data from purposely designed numerical simulations are presented to show how much the maximum r value is worsened by increasing the data uncertainty. The corresponding confidence interval of r is determined by using the Fisher r → Z transform.

The main objective of the present study was to classify doctoral programs with Quality Mention in Psychology based on their scientific productivity. For this purpose, articles in the Web of Science published by professors teaching in these doctoral programs were analyzed. In addition, we analyzed scientific journals in which these professors tend to publish more papers and the evolution in the number of papers published until 2009. Results showed that the most productive doctoral program was the Neurosciences program at the University of Oviedo. This program showed a ratio of 40 articles--published in journals included in Journal Citation Reports--by each professor. In contrast, other programs did not reach a ratio of 10 articles per professor. Regarding journals, results showed that 9 out of the 20 most popular journals are Hispanic and a gradual increase in the number of published papers was also observed. Lastly, results and implications for quality assessment are discussed.

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.

Objective The purposes of this study were to investigate the overall publication rates of presentations at the Association of Chiropractic Colleges Educational Conference/Research Agenda Conference (ACC/RAC) meetings (2002–2008), differences in the publication rates of platform vs poster presentations, and the consistency of the meeting abstract compared to the full-length journal article. Methods Abstracts were obtained from proceedings published in the Journal of Chiropractic Education. Literature searches using PubMed and the Index to the Chiropractic Literature (ICL) were performed to locate peer-reviewed journal articles based upon those abstracts. Whether the article was based upon a poster or platform presentation, and the congruence of the information in the abstract and article were recorded. Results We identified 776 proceeding abstracts, 249 of which eventually were published between 2002 and 2012. The overall publication rate was 32.2%. A total of 42.7% of platform presentations eventually were published vs 20.3% of posters. Congruency showed that 43.2% had the same title as the meeting abstract, 59.7% had the same authorship, and 88.8% had the same methods. Conclusion Publication rates of abstracts from spine and orthopedic surgery national meetings range from 34% to 59%. The ACC/RAC meetings have similar publication rates. More platform than poster presentations reach full publication. The congruency of ACC/RAC abstracts to published articles is higher than national meetings in other fields. PMID:24295363

Summary evaluations of the performance of laminar-flow control (LFC) leading edge test articles on a NASA JetStar aircraft are presented. Statistics, presented for the test articles' performance in haze and cloud situations, as well as in clear air, show a significant effect of cloud particle concentrations on the extent of laminar flow. The cloud particle environment was monitored by two instruments, a cloud particle spectrometer (Knollenberg probe) and a charging patch. Both instruments are evaluated as diagnostic aids for avoiding laminar-flow detrimental particle concentrations in future LFC aircraft operations. The data base covers 19 flights in the simulated airline service phase of the NASA Leading-Edge Flight-Test (LEFT) Program.

One of the obstacles to using them is difficulty with finding a method which would allow successful cooperation between concrete and timber, which has been proposed by the authors of the present article. The modern idea of sustainable construction design requires the use of new more environmentally-friendly solutions. Wood as an ecological material is easily accessible, less energy-consuming, and under certain conditions more corrosion-resistant than steel. The analysis presented in the article showed that cooperation between a wooden beam and a concrete slab on profiled steel sheeting is possible. The analysed composite beam has a greater load capacity and stiffness than the wooden beam.

The Physics of Equestrian Show Jumping

Stinner, Art

This article discusses the kinematics and dynamics of equestrian show jumping. For some time I have attended a series of show jumping events at Spruce Meadows, an international equestrian center near Calgary, Alberta, often referred to as the "Wimbledon of equestrian jumping." I have always had a desire to write an article such as this one, but when I searched the Internet for information and looked at YouTube presentations, I could only find simplistic references to Newton's laws and the conservation of mechanical energy principle. Nowhere could I find detailed calculations. On the other hand, there were several biomechanical articles with empirical reports of the results of kinetic and dynamic investigations of show jumping using high-speed digital cameras and force plates. They summarize their results in tables that give information about the motion of a horse jumping over high fences (1.40 m) and the magnitudes of the forces encountered when landing. However, they do not describe the physics of these results.

Specific skin signs as a cutaneous marker of diabetes mellitus and the prediabetic state - a systematic review.

PubMed

Bustan, Rewend Salman; Wasim, Daanyaal; Yderstræde, Knud Bonnet; Bygum, Anette

2017-01-01

Diabetes mellitus and the prediabetic state are associated with a number of skin manifestations. This study is a systematic review of the following manifestations: acanthosis nigricans (AN), skin tags (ST), diabetic dermopathy (DD), rubeosis faciei (RF), pruritus (PR), granuloma annulare (GA), necrobiosis lipoidica (NL), scleroedema diabeticorum (SD) and bullosis diabeticorum (BD). These conditions possibly relate to underlying diabetogenic mechanisms. Our aim was to determine whether skin signs are feasible as cutaneous markers for the prediabetic or diabetic state. Data were collected from the databases PubMed, Embase and Cochrane. Articles were excluded if the populations presented with comorbidities or received treatment with drugs affecting the skin. Also, animal studies, studies with poor methodology and pilot studies were excluded. Among the 34 included original articles, an association with diabetes was shown as follows: in eight articles with AN, five articles with ST, three articles with GA, two articles with NL, PR and SD respectively and in one article with RF. Three papers indirectly showed an association of DD with diabetes. Association between bullous skin lesions and diabetes was only documented by case reports and case series. The results indicate a benefit of diabetes screening in individuals presenting with AN, ST or BD. Further studies are required to enlighten a possible association with RF, GA, SD or NL. Until such studies are available, it is advisable to screen individuals with the skin lesions presented by measuring their glycated haemoglobin.

Perceiving the present and a systematization of illusions.

Over the history of the study of visual perception there has been great success at discovering countless visual illusions. There has been less success in organizing the overwhelming variety of illusions into empirical generalizations (much less explaining them all via a unifying theory). Here, this article shows that it is possible to systematically organize more than 50 kinds of illusion into a 7 × 4 matrix of 28 classes. In particular, this article demonstrates that (1) smaller sizes, (2) slower speeds, (3) greater luminance contrast, (4) farther distance, (5) lower eccentricity, (6) greater proximity to the vanishing point, and (7) greater proximity to the focus of expansion all tend to have similar perceptual effects, namely, to (A) increase perceived size, (B) increase perceived speed, (C) decrease perceived luminance contrast, and (D) decrease perceived distance. The detection of these empirical regularities was motivated by a hypothesis, called "perceiving the present," that the visual system possesses mechanisms for compensating neural delay during forward motion. This article shows how this hypothesis predicts the empirical regularity. 2008 Cognitive Science Society, Inc.

Stability investigations of relaxing molecular gas flows. Results and perspectives

Grigor'ev, Yurii N.; Ershov, Igor V.

2017-10-01

This article presents results of systematic investigations of a dissipative effect which manifests itself as the growth of hydrodynamic stability and suppression of turbulence in relaxing molecular gas flows. The effect can be a new way for control stability and laminar turbulent transition in aerodynamic flows. The consideration of suppression of inviscid acoustic waves in 2D shear flows is presented. Nonlinear evolution of large-scale vortices and Kelvin — Helmholtz waves in relaxing shear flows are studied. Critical Reynolds numbers in supersonic Couette flows are calculated analytically and numerically within the framework of both classical linear and nonlinear energy hydrodynamic stability theories. The calculations clearly show that the relaxation process can appreciably delay the laminar-turbulent transition. The aim of this article is to show the new dissipative effect, which can be used for flow control and laminarization.

This data article contains data related to the research article entitled, “A proteomic analysis of p53-independent induction of apoptosis by bortezomib in 4T1 breast cancer cell line” by Yerlikaya et al. [1]. The research article presented 2-DE and nLC-MS/MS based proteomic analysis of proteasome inhibitor bortezomib-induced changes in the expression of cellular proteins. The report showed that GRP78 and TCEB2 were over-expressed in response to treatment with bortezomib for 24 h. In addition, the report demonstrated that Hsp70, the 26S proteasome non-ATPase regulatory subunit 14 and sequestosome 1 were increased at least 2 fold in p53-deficient 4T1 cells. The data here show for the first time the increased expressions of Card10, Dffb, Traf3 and Trp53bp2 in response to inhibition of the 26S proteasome. The information presented here also shows that both Traf1 and Xiap (a member of IAPs) are also downregulated simultaneously upon proteasomal inhibition. The increases in the level of Card10 and Trp53bp2 proteins were verified by Western blot analysis in response to varying concentrations of bortezomib for 24 h. PMID:26217687

Public understanding of chemistry research in print news

NASA Astrophysics Data System (ADS)

Hands, Michael D., Jr.

Despite numerous calls for improving scientific literacy, many American adults show a lack of understanding of experiments, scientific study, and scientific inquiry. News media is one important avenue for science learning, but previous research investigating health and/or environmental science news has shown that it is inconsistent in the presentation of scientific research limitations, potentially impacting reader understanding. In the first phase of this dissertation, seventeen news articles reporting on a single chemistry research article, along with associated press releases and research articles, were analyzed using move analysis to determine the structure of each type of text. It was found that the overall structure of each text genre was similar, with the main difference being that research articles start by presenting background information, while the others lead with highlighting overall research outcomes. Analysis of the steps revealed that, as seen for health and environmental science news articles, descriptions of the study limitations and methods were generally omitted in the news articles. Using these findings, a pilot study was conducted where study limitations were added to a chemistry research news article and the effect of its presence on staff members employed at a large Midwestern university (n=12) and science faculty employed at the same institution (n=6) was explored. Interviews with the participants revealed that including limitations enhanced readers' ability to identify conclusions and evaluate claims, but decreased their trust in the information. In the final part of this study, the trends seen in the previous phase were explored to determine their generalizability. Members of the public (n=232) and science faculty (n=191) read a randomly assigned news article either presenting or omitting the study limitations and research methods. Participants reading articles presenting limitations were able to evaluate the reasonableness of claims based on the article better than those who read the article omitting limitations when accounting for their views on the tentativeness of science (ToS). Presenting limitations was important in identifying unreasonable claims for both public and science faculty, while ToS views predicted ability to identify reasonable claims for the public. Including limitations also decreased readers' trust in the conclusions of the research. However, it did not impact their ability to determine the conclusions of the research and including methods did not have any effect on the measured outcomes.

The fifth version of the American Psychiatric Association's classification, DSM, was released in May 2013. Its completion was preceded by years of intensive discussions, clinical trials and secondary data analysis, which were aimed at as best as possible reflecting of clinical reality. In the present article review of literature was presented, showing the range of work connected with the area of widely understood sexual disorders as well as the most important changes regarding it that are included in DSM-5. Review of Polish literature published in the last three years (2011-2013) regarding sexual issues in selected scientific journals: Seksuologia Polska, Ginekologia Polska, Psychiatria Polska, Psychoterapia was also conducted. It was aimed at analysis of basic research trends within the area of sexual disorders in Poland. The review shows that there were relatively not many articles, they were concentrated on interdisciplinary issues and clinical populations of patients suffering from disorders different than sexual. It was noticed that there were no articles on paraphilias, and at the same time publications regarding forensic sexology were present. It would be advisable to publish reports form scientific congresses of sexology on a more regular basis, that would perhaps inspire further research in the field of sexology in our country.

Taking climate change seriously: An analysis of op-ed articles in Spanish press.

In this article, we study the evolution of opinion genres regarding climate change in three Spanish newspapers ( El País, El Mundo, and ABC). Analyzing the op-ed articles in these newspapers, we observe a significant change in the evolution of opinion. While denialism was very present in conservative press in 2007, 7 years later it is almost absent from El Mundo, and its presence in ABC is much lower and inactive: this shows that scientific consensus has prevailed over time and Spanish denialism has weakened, exclusively supported by political arguments by the most conservative parties.

Imaging of juvenile spondyloarthritis. Part II: Ultrasonography and magnetic resonance imaging

2017-01-01

Juvenile spondyloarthropathies are mainly manifested by symptoms of peripheral arthritis and enthesitis. Early involvement of sacroiliac joints and spine is exceptionally rare in children; this usually happens in adulthood. Conventional radiographs visualize late inflammatory lesions. Early diagnosis is possible with the use of ultrasonography and magnetic resonance imaging. The first part of the article presented classifications and radiographic presentation of juvenile spondyloarthropathies. This part discusses changes seen on ultrasonography and magnetic resonance imaging. In patients with juvenile spondyloarthropathies, these examinations are conducted to diagnose inflammatory lesions in peripheral joints, tendon sheaths, tendons and bursae. Moreover, magnetic resonance also shows subchondral bone marrow edema, which is considered an early sign of inflammation. Ultrasonography and magnetic resonance imaging do not show specific lesions for any rheumatic disease. Nevertheless, they are conducted for early diagnosis, treatment monitoring and identifying complications. This article presents a spectrum of inflammatory changes and discusses the diagnostic value of ultrasonography and magnetic resonance imaging. PMID:29075522

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

PubMed Central

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

2017-05-01

The article presents the analysis of metrological properties of a two-current-source supplied circuit. It includes such data as precise and simplified equations for two circuit output voltages in the function of relative resistance increments of sensors. Moreover, graphs showing nonlinearity coefficients of both output voltages for two resistance increments varying widely are presented. Graphs of transfer resistances, depending on relative increments of sensors resistance were also created. The article also contains a description of bridge-based circuit realization with the use of a computer and a data acquisition (DAQ) card. Laboratory measurement of the difference and sum of relative resistance increments of two resistance decade boxes were carried out indirectly with the use of the created measurement system. Measurement errors were calculated and included in the article, as well.

Optimal Price Decision Problem for Simultaneous Multi-article Auction and Its Optimal Price Searching Method by Particle Swarm Optimization

NASA Astrophysics Data System (ADS)

Masuda, Kazuaki; Aiyoshi, Eitaro

We propose a method for solving optimal price decision problems for simultaneous multi-article auctions. An auction problem, originally formulated as a combinatorial problem, determines both every seller's whether or not to sell his/her article and every buyer's which article(s) to buy, so that the total utility of buyers and sellers will be maximized. Due to the duality theory, we transform it equivalently into a dual problem in which Lagrange multipliers are interpreted as articles' transaction price. As the dual problem is a continuous optimization problem with respect to the multipliers (i.e., the transaction prices), we propose a numerical method to solve it by applying heuristic global search methods. In this paper, Particle Swarm Optimization (PSO) is used to solve the dual problem, and experimental results are presented to show the validity of the proposed method.

Seeing Change in Time: Video Games to Teach about Temporal Change in Scientific Phenomena

NASA Astrophysics Data System (ADS)

Corredor, Javier; Gaydos, Matthew; Squire, Kurt

2014-06-01

This article explores how learning biological concepts can be facilitated by playing a video game that depicts interactions and processes at the subcellular level. Particularly, this article reviews the effects of a real-time strategy game that requires players to control the behavior of a virus and interact with cell structures in a way that resembles the actual behavior of biological agents. The evaluation of the video game presented here aims at showing that video games have representational advantages that facilitate the construction of dynamic mental models. Ultimately, the article shows that when video game's characteristics come in contact with expert knowledge during game design, the game becomes an excellent medium for supporting the learning of disciplinary content related to dynamic processes. In particular, results show that students who participated in a game-based intervention aimed at teaching biology described a higher number of temporal-dependent interactions as measured by the coding of verbal protocols and drawings than students who used texts and diagrams to learn the same topic.

Introduction  In Brazil, estimates show that 14.7% of the adult population smokes, and changes in smell and taste arising from tobacco consumption are largely present in this population, which is an aggravating factor to these dysfunctions. Objectives  The objective of this study is to systematically review the findings in the literature about the influence of smoking on smell and taste. Data Synthesis  Our research covered articles published from January 1980 to August 2014 in the following databases: MEDLINE (accessed through PubMed), LILACS, Cochrane Library, and SciELO. We conducted separate lines of research: one concerning smell and the other, taste. We analyzed all the articles that presented randomized controlled studies involving the relation between smoking and smell and taste. Articles that presented unclear methodologies and those whose main results did not target the smell or taste of the subjects were excluded. Titles and abstracts of the articles identified by the research strategy were evaluated by researchers. We included four studies, two of which were exclusively about smell: the first noted the relation between the perception of puff strength and nicotine content; the second did not find any differences in the thresholds and discriminative capacity between smokers and nonsmokers. One article considered only taste and supports the relation between smoking and flavor, another considered both sensory modalities and observes positive results toward the relation immediately after smoking cessation. Conclusion  Three of the four studies presented positive results for the researched variables. PMID:29371903

Learning the preferences of physicians for the organization of result lists of medical evidence articles.

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 that physicians assign significant value to the 1st position on a list and they expect that the most relevant article is presented first. Whilst physicians still prefer obtaining a correctly placed article on position 2, they are also quite satisfied with misplaced relevant article. Low consideration of the 3rd position was uniformly confirmed. Our findings confirm the importance of placing the most relevant article on the 1st position on a list and the importance paid to position on a list significantly diminishes after the 2nd position. The derived value functions may be used by developers of clinical decision support applications to decide how best to organize medical knowledge for decision making and to create personalized evaluation measures that can augment typical measures used to evaluate information retrieval systems.

The neglected 95%: why American psychology needs to become less American.

PubMed

Arnett, Jeffrey J

2008-10-01

This article proposes that psychological research published in APA journals focuses too narrowly on Americans, who comprise less than 5% of the world's population. The result is an understanding of psychology that is incomplete and does not adequately represent humanity. First, an analysis of articles published in six premier APA journals is presented, showing that the contributors, samples, and editorial leadership of the journals are predominantly American. Then, a demographic profile of the human population is presented to show that the majority of the world's population lives in conditions vastly different from the conditions of Americans, underlining doubts of how well American psychological research can be said to represent humanity. The reasons for the narrowness of American psychological research are examined, with a focus on a philosophy of science that emphasizes fundamental processes and ignores or strips away cultural context. Finally, several suggestions for broadening the scope of American psychology are offered.

Linear time-dependent reference intervals where there is measurement error in the time variable-a parametric approach.

PubMed

Gillard, Jonathan

2015-12-01

This article re-examines parametric methods for the calculation of time specific reference intervals where there is measurement error present in the time covariate. Previous published work has commonly been based on the standard ordinary least squares approach, weighted where appropriate. In fact, this is an incorrect method when there are measurement errors present, and in this article, we show that the use of this approach may, in certain cases, lead to referral patterns that may vary with different values of the covariate. Thus, it would not be the case that all patients are treated equally; some subjects would be more likely to be referred than others, hence violating the principle of equal treatment required by the International Federation for Clinical Chemistry. We show, by using measurement error models, that reference intervals are produced that satisfy the requirement for equal treatment for all subjects. © The Author(s) 2011.

Nutrigenomics and nutrigenetics (NGx) are fields of research that have raised significant expectations about their potential benefits. This article presents empirical data from an online survey seeking the opinions of NGx researchers (n=126) regarding the achievability of the potential benefits of NGx, the time envisioned for their realization, the motives that may lead to their explicit mention in scientific peer-reviewed articles and the audience(s) targeted by NGx researchers when reporting their results in such articles. Results show that caution should be taken to avoid the risks associated with biohype and the premature dissemination of the potential benefits of NGx among various audiences.

Evaluating the evidence base for relational frame theory: a citation analysis.

PubMed

Dymond, Simon; May, Richard J; Munnelly, Anita; Hoon, Alice E

2010-01-01

Relational frame theory (RFT) is a contemporary behavior-analytic account of language and cognition. Since it was first outlined in 1985, RFT has generated considerable controversy and debate, and several claims have been made concerning its evidence base. The present study sought to evaluate the evidence base for RFT by undertaking a citation analysis and by categorizing all articles that cited RFT-related search terms. A total of 174 articles were identified between 1991 and 2008, 62 (36%) of which were empirical and 112 (64%) were nonempirical articles. Further analyses revealed that 42 (68%) of the empirical articles were classified as empirical RFT and 20 (32%) as empirical other, whereas 27 (24%) of the nonempirical articles were assigned to the nonempirical reviews category and 85 (76%) to the nonempirical conceptual category. In addition, the present findings show that the majority of empirical research on RFT has been conducted with typically developing adult populations, on the relational frame of sameness, and has tended to be published in either The Psychological Record or the Journal of the Experimental Analysis of Behavior. Overall, RFT has made a substantial contribution to the literature in a relatively short period of time.

Where are the SVHCs?: 10 years consumer's 'right to know' about substances of very high concern.

PubMed

Klaschka, Ursula

2017-01-01

The European chemicals regulation REACH includes the legal duty for suppliers to inform consumers on request about the presence of substances of very high concern (SVHCs) in articles. Since this requirement has been in force now for 10 years, the intention of this study was to find out whether information on SVHCs is adequately communicated to the consumer today. Data on the presence of SVHCs in articles were collected as a prerequisite for the subsequent requests for a targeted choice of articles to examine the operability of the 'right to know.' Literature data show that SVHCs have been measured and described in a large variety of commodities. 32% of 334 information requests for articles which were suspected to contain SVHCs were answered by suppliers and a minor number of these answers were of good quality. Only two respondents indicated the presence of SVHCs in their articles. Suppliers are not legally obliged to respond to requests if their articles are free of SVHCs. Therefore, the absence of a response might be interpreted as an indication that SVHCs are present below 0.1% in the articles in question. However, there are certain doubts that only two out of 334 articles suspected contain SVHCs. The data question whether the ambitious aims of the SVHC regime can be achieved under the present conditions. Measures are proposed on how to improve implementation of the information requirement and to amend the legal criteria in the upcoming REACH revision.

Knowing pornography.

PubMed

Jensen, R

1996-03-01

This personal narrative presents an analysis of the impact of heterosexual pornography on constructs of male sexuality in the US based upon personal use. After a brief introduction, the essay reviews the radical feminist critique of pornography and shows how this critique arises from the understanding that, in patriarchal societies, male domination is the central dynamic in sexual relations. Next, the article discusses how the author adopted the feminist technique of presenting an embodied narrative for this article and how he arrived at this position. The article continues by describing the author's personal history of pornography use and how the use of pornography 1) contributed to his sex education, 2) caused him to objectify women, 3) created or reinforced desires for specific sex behaviors, 4) shaped and constrained his sexual imagination with standardized scripts, 5) reinforced the idea that women of color are "exotic primitives," 6) eroticized violence, and 7) reinforced his need for a sense of control over women and their sexuality.

Molander, Linda; Breitholtz, Magnus; Andersson, Patrik L; Rybacka, Aleksandra; Rudén, Christina

2012-10-01

It is widely acknowledged that the management of risks associated with chemicals in articles needs to be improved. The EU environmental policy states that environmental damage should be rectified at source. It is therefore motivated that the risk management of substances in articles also takes particular consideration to those substances identified as posing a risk in different environmental compartments. The primary aim of the present study was to empirically analyze to what extent the regulation of chemicals in articles under REACH is coherent with the rules concerning chemicals in the Sewage Sludge Directive (SSD) and the Water Framework Directive (WFD). We also analyzed the chemical variation of the organic substances regulated under these legislations in relation to the most heavily used chemicals. The results show that 16 of 24 substances used in or potentially present in articles and regulated by the SSD or the WFD are also identified under REACH either as a substance of very high concern (SVHC) or subject to some restrictions. However, for these substances we conclude that there is limited coherence between the legislations, since the identification as an SVHC does not in itself encompass any use restrictions, and the restrictions in REACH are in many cases limited to a particular use, and thus all other uses are allowed. Only a minor part of chemicals in commerce is regulated and these show a chemical variation that deviates from classical legacy pollutants. This warrants new tools to identify potentially hazardous chemicals in articles. We also noted that chemicals monitored in the environment under the WFD deviate in their chemistry from the ones regulated by REACH. In summary, we argue that to obtain improved resource efficiency and a sustainable development it is necessary to minimize the input of chemicals identified as hazardous to health or the environment into articles.

Insights into teaching quantum mechanics in secondary and lower undergraduate education

NASA Astrophysics Data System (ADS)

Krijtenburg-Lewerissa, K.; Pol, H. J.; Brinkman, A.; van Joolingen, W. R.

2017-06-01

This study presents a review of the current state of research on teaching quantum mechanics in secondary and lower undergraduate education. A conceptual approach to quantum mechanics is being implemented in more and more introductory physics courses around the world. Because of the differences between the conceptual nature of quantum mechanics and classical physics, research on misconceptions, testing, and teaching strategies for introductory quantum mechanics is needed. For this review, 74 articles were selected and analyzed for the misconceptions, research tools, teaching strategies, and multimedia applications investigated. Outcomes were categorized according to their contribution to the various subtopics of quantum mechanics. Analysis shows that students have difficulty relating quantum physics to physical reality. It also shows that the teaching of complex quantum behavior, such as time dependence, superposition, and the measurement problem, has barely been investigated for the secondary and lower undergraduate level. At the secondary school level, this article shows a need to investigate student difficulties concerning wave functions and potential wells. Investigation of research tools shows the necessity for the development of assessment tools for secondary and lower undergraduate education, which cover all major topics and are suitable for statistical analysis. Furthermore, this article shows the existence of very diverse ideas concerning teaching strategies for quantum mechanics and a lack of research into which strategies promote understanding. This article underlines the need for more empirical research into student difficulties, teaching strategies, activities, and research tools intended for a conceptual approach for quantum mechanics.

Since the German Anti-Corruption-Law (1997) the areas of financial support, sponsoring and corruption in medicine are analyzed much more intensively. This article sketches the crucial points of the debate on medical funding and shows the consequences of the new jurisdiction. Most important is the balance between a transparent documentation and a too-far-reaching bureaucracy, which hinders medical research. Finally, this article presents core principles as helpful rules in practice.

Morales-Morales, Cornelio; Adam-Medina, Manuel; Cervantes, Ilse; Vela-Valdés and, Luis G.; García Beltrán, Carlos Daniel

2013-01-01

This article proposes a virtual sensor for piecewise linear systems based on observability analysis that is in function of a commutation law related with the system's outpu. This virtual sensor is also known as a state estimator. Besides, it presents a detector of active mode when the commutation sequences of each linear subsystem are arbitrary and unknown. For the previous, this article proposes a set of virtual estimators that discern the commutation paths of the system and allow estimating their output. In this work a methodology in order to test the observability for piecewise linear systems with discrete time is proposed. An academic example is presented to show the obtained results.

1989-01-01

The purpose of this study was to identify objectively a hierarchical ranking of journals for health sciences librarians with faculty status. Such a guideline can indicate a journal's value for promotion and tenure consideration. Lists of recent research articles (1982-1986) in health sciences librarianship, and articles written by health sciences librarians, were compiled by searching Social SCISEARCH and MEDLINE. The journals publishing those articles are presented. Results show BMLA as the most prominent journal in the field. Therefore, citations from articles in BMLA from 1982 to 1986 were chosen as a sample for citation analysis. Citation analysis was employed to identify the most frequently cited journals. Some characteristics of the citations in BMLA are also discussed. The ranking of journals based on citation frequency, as a result, was identified. PMID:2655785

Closer look at autism and the measles-mumps-rubella vaccine.

PubMed

Hensley, Emily; Briars, Leslie

2010-01-01

To educate pharmacists regarding the hypothesis that the measles-mumps-rubella (MMR) vaccine is linked to the development of autism. Articles published from 1998 to 2009 were identified through electronic searches of Medline. Articles were included if they evaluated or reviewed a possible link between the MMR vaccine and autism or discussed MMR epidemiology, legal proceedings involving the MMR vaccine and autism, or health professionals' impact on immunization decisions. A total of 27 articles were identified. Of the articles, 74% (20 of 27) were included in the review because of their relevance to the study topic. The evidence presented does not show a causal relationship between the MMR vaccine and autism. Myths presented to potentially support any relationship between the MMR vaccine and autism have not been proven. Expert testimony refuting initial scientific theories has led to Supreme Court decisions that do not support a link between the MMR vaccine and autism. Pharmacists and all health care providers are responsible for informing and educating parents and families regarding this information so that they can make informed decisions about immunizations.

Trypophobia: What Do We Know So Far? A Case Report and Comprehensive Review of the Literature

PubMed Central

Martínez-Aguayo, Juan Carlos; Lanfranco, Renzo C.; Arancibia, Marcelo; Sepúlveda, Elisa; Madrid, Eva

2018-01-01

In this article, we describe the case of a girl who suffers from a phobia to repetitive patterns, known as trypophobia. This condition has not yet been recognised by diagnostic taxonomies such as the Diagnostic and Statistical Manual of Mental Disorders. Trypophobia usually involves an intense and disproportionate fear towards holes, repetitive patterns, protrusions, etc., and, in general, images that present high-contrast energy at low and midrange spatial frequencies. It is commonly accompanied by neurovegetative symptoms. In the case we present here, the patient also suffered from generalised anxiety disorder and was treated with sertraline. After she was diagnosed, she showed symptoms of both fear and disgust towards trypophobic images. After some time following treatment, she only showed disgust towards said images. We finish this case report presenting a comprehensive literature review of the peer reviewed articles we retrieved after an exhaustive search about trypophobia, we discuss how this case report contributes to the understanding of this anxiety disorder, and what questions future studies should address in order to achieve a better understanding of trypophobia.

Applicability of discovery science approach to determine biological effects of mobile phone radiation.

Leszczynski, Dariusz; Nylund, Reetta; Joenväärä, Sakari; Reivinen, Jukka

2004-02-01

We argue that the use of high-throughput screening techniques, although expensive and laborious, is justified and necessary in studies that examine biological effects of mobile phone radiation. The "case of hsp27 protein" presented here suggests that even proteins with only modestly altered (by exposure to mobile phone radiation) expression and activity might have an impact on cell physiology. However, this short communication does not attempt to present the full scientific evidence that is far too large to be presented in a single article and that is being prepared for publication in three separate research articles. Examples of the experimental evidence presented here were designed to show the flow of experimental process demonstrating that the use of high-throughput screening techniques might help in rapid identification of the responding proteins. This, in turn, can help in speeding up of the process of determining whether these changes might affect human health.*

2010-01-01

Progressive posterior cortical dysfunction (PPCD) is an insidious syndrome characterized by prominent disorders of higher visual processing. It affects both dorsal (occipito-parietal) and ventral (occipito-temporal) pathways, disturbing visuospatial processing and visual recognition, respectively. We report a case of a 67-year-old woman presenting with progressive impairment of visual functions. Neurologic examination showed agraphia, alexia, hemispatial neglect (left side visual extinction), complete Balint’s syndrome and visual agnosia. Magnetic resonance imaging showed circumscribed atrophy involving the bilateral parieto-occipital regions, slightly more predominant to the right. Our aim was to describe a case of this syndrome, to present a video showing the main abnormalities, and to discuss this unusual presentation of dementia. We believe this article can contribute by improving the recognition of PPCD. PMID:29213665

Industry 4.0 Concept Introduction into Construction SMEs

2017-10-01

The article presents a general idea of Industry 4.0 concept with the introduction presenting descriptions of the most important aspects in terms of production and construction industry development. The importance of the SME sector is stressed showing that this group of companies plays significant role in the European economy. The main objective of the article is to define and show possible research areas connected with the introduction of Industry 4.0 concept into SMEs with the main focus on the construction sector. For this purpose, an analysis was made, based on the most recent literature, to point out actual needs in the SMEs sector in terms of its evolution into 4.0 level. What is more, the analysis was performed based on the most popular articles published in journals available in Thomson Reuters Web of Science Core Collection database regarding Industry 4.0 concept in the last decade showing the actual change of interest in this filed, taking into account possibility of usage of this concept in the construction and production sector. Authors tried to describe current knowledge regarding Industry 4.0 introduction for SMEs. Performed analysis showed that there is a wide spectrum of disciplines that are affected by the Industry 4.0 that needs to be examined considering introduction into SMEs. Study also showed that multidiscipline approach was not investigated so far to create special rules, procedures and methods and know-how designed for introduction of main principles of Industry 4.0 in the SME sector. Authors came to the conclusions that there should be more stress put into research in this field especially taking into account the huge potential which lies in SME sector in terms of global economic strength.

Article retracted, but the message lives on.

PubMed

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.

A collective theory of happiness: words related to the word "happiness" in Swedish online newspapers.

PubMed

Garcia, Danilo; Sikström, Sverker

2013-06-01

It may be suggested that the representation of happiness in online media is collective in nature because it is a picture of happiness communicated by relatively few individuals to the masses. The present study is based on articles published in Swedish daily online newspapers in 2010; the data corpus comprises 1.5 million words. We investigated which words were most (un)common in articles containing the word "happiness" as compared with articles not containing this word. The results show that words related to people (by use of all relevant pronouns: you/me and us/them); important others (e.g., grandmother, mother); the Swedish royal wedding (e.g., Prince Daniel, Princess Victoria); and the FIFA World Cup (e.g., Zlatan, Argentina, Drogba) were highly recurrent in articles containing the word happiness. In contrast, words related to objects, such as money (e.g., millions, billions), bestselling gadgets (e.g., iPad, iPhone), and companies (e.g., Google, Windows), were predictive of contexts not recurrent with the word happiness. The results presented here are in accordance with findings in the happiness literature showing that relationships, not material things, are what make people happy. We suggest that our findings mirror a collective theory of happiness, that is, a shared picture or agreement, among members of a community, concerning what makes people happy. The fact that this representation is made public on such a large scale makes it collective in nature.

Metallic iron for environmental remediation: A review of reviews.

PubMed

Noubactep, Chicgoua

2015-11-15

This article critically evaluates recent review articles on using metallic iron (Fe(0)) for environmental remediation in order to provide insight for more efficient Fe(0)-based systems. The presentation is limited to peer-reviewed articles published during 2014 and 2015, excluding own contributions, dealing mostly with granular Fe(0). A literature search was conducted up to June 15th 2015 using Science Direct, SCOPUS, Springer and Web of Science databases. The search yielded eight articles that met the final inclusion criteria. The evaluation clearly shows that seven articles provide a narrative description of processes occurring in the Fe(0)/H20 system according to the concept that Fe(0) is a reducing agent. Only one article clearly follows a different path, presenting Fe(0) as a generator of adsorbing (hydroxides, oxides) and reducing (Fe(II), H/H2) agents. The apparent discrepancies between the two schools are identified and extensively discussed based on the chemistry of the Fe(0)/H20 system. The results of this evaluation indicate clearly that research on 'Fe(0) for environmental remediation' is in its infancy. Despite the current paucity of reliable data for the design of efficient Fe(0)-based systems, this review demonstrates that sensible progress could be achieved within a short period of time, specific recommendations to help guide future research are suggested.

The comparison between a quasi-static analytical solution for Stefan numbers less than one and numerical solutions shows good agreement. The computational results of phase change with internal heat generation show how convection cells form in the liquid region. A scale analysis of the same problem shows four distinct regions of the melting process.

Towards Automatic Classification of Wikipedia Content

NASA Astrophysics Data System (ADS)

Szymański, Julian

Wikipedia - the Free Encyclopedia encounters the problem of proper classification of new articles everyday. The process of assignment of articles to categories is performed manually and it is a time consuming task. It requires knowledge about Wikipedia structure, which is beyond typical editor competence, which leads to human-caused mistakes - omitting or wrong assignments of articles to categories. The article presents application of SVM classifier for automatic classification of documents from The Free Encyclopedia. The classifier application has been tested while using two text representations: inter-documents connections (hyperlinks) and word content. The results of the performed experiments evaluated on hand crafted data show that the Wikipedia classification process can be partially automated. The proposed approach can be used for building a decision support system which suggests editors the best categories that fit new content entered to Wikipedia.

Anhydrous trifluoroacetic acid pretreatment converts insoluble polyglutamine peptides to soluble monomers.

2015-12-01

The data provided in this article are related to the research article entitled "Unaided trifluoroacetic acid pretreatment solubilizes polyglutamine (polyGln) peptides and retains their biophysical properties of aggregation" by Burra and Thakur (in press) [1]. This research article reports data from size exclusion chromatography (SEC), reversed phase-high performance liquid chromatography (RP-HPLC) and mass spectrometry (MS) assays. This data show that trifluoroacetic acid (TFA) has the ability to convert insoluble polyGln peptides to soluble monomers. The data also clarify the possibility of trifluoroacetylation modification caused due to TFA. We hope the data presented here will enhance the understanding of polyGln disaggregation and solubilization. For more insightful and useful discussions, see the research article published in Analytical Biochemistry: Methods in the Biological Sciences (Burra and Thakur, in press [1]).

Presentation-Oriented Visualization Techniques.

Kosara, Robert

2016-01-01

Data visualization research focuses on data exploration and analysis, yet the vast majority of visualizations people see were created for a different purpose: presentation. Whether we are talking about charts showing data to help make a presenter's point, data visuals created to accompany a news story, or the ubiquitous infographics, many more people consume charts than make them. Traditional visualization techniques treat presentation as an afterthought, but are there techniques uniquely suited to data presentation but not necessarily ideal for exploration and analysis? This article focuses on presentation-oriented techniques, considering their usefulness for presentation first and any other purposes as secondary.

Research on publication trends in journal articles on sleep disorders (SDs) and the associated methodologies by using text mining has been limited. The present study involved text mining for terms to determine the publication trends in sleep-related journal articles published during 2000-2013 and to identify associations between SD and methodology terms as well as conducting statistical analyses of the text mining findings. SD and methodology terms were extracted from 3,720 sleep-related journal articles in the PubMed database by using MetaMap. The extracted data set was analyzed using hierarchical cluster analyses and adjusted logistic regression models to investigate publication trends and associations between SD and methodology terms. MetaMap had a text mining precision, recall, and false positive rate of 0.70, 0.77, and 11.51%, respectively. The most common SD term was breathing-related sleep disorder, whereas narcolepsy was the least common. Cluster analyses showed similar methodology clusters for each SD term, except narcolepsy. The logistic regression models showed an increasing prevalence of insomnia, parasomnia, and other sleep disorders but a decreasing prevalence of breathing-related sleep disorder during 2000-2013. Different SD terms were positively associated with different methodology terms regarding research design terms, measure terms, and analysis terms. Insomnia-, parasomnia-, and other sleep disorder-related articles showed an increasing publication trend, whereas those related to breathing-related sleep disorder showed a decreasing trend. Furthermore, experimental studies more commonly focused on hypersomnia and other SDs and less commonly on insomnia, breathing-related sleep disorder, narcolepsy, and parasomnia. Thus, text mining may facilitate the exploration of the publication trends in SDs and the associated methodologies.

Pregnancy and delivery are well-established risk factors for pelvic floor dysfunction (PFD), but the physiopathology, such as the delivery route, is not well understood. This study evaluated the impact of delivery route on the pelvic floor muscles via 3D ultrasound. This review is registered in the PROSPERO database. The criteria for inclusion were prospective studies with 3D translabial ultrasound assessment in primigravida women during pregnancy and postpartum published in English, Spanish or Portuguese between 1980 and 2016. We excluded studies that did not include the topic of urogenital hiatus measurement and literature reviews. The MeSH terms were obstetric delivery, postpartum period, labor, parturition, three-dimensional images, ultrasonography, pelvic floor, and pelvic floor disorders. The search retrieved 155 articles. After analysis, 6 articles were included. Four studies showed that vaginal delivery (VD) was associated with a larger hiatal area. One study associated the hiatal area with levator ani muscle (LAM) defects in VD. Four articles evaluated the bladder neck, 3 of which showed a significant increase in bladder neck mobility associated with VD and 1 showed decreased bladder neck elevation, not associated with the delivery mode; the first 3 articles all evaluated LAM injuries and showed an association between VD and LAM injury. Women who underwent VD presented defects of the puborectalis muscle. Vaginal delivery was associated with a higher number of LAM injuries, puborectalis defects, increased bladder neck mobility, and enlargement of the hiatal area.

Experimental studies were carried out on a single-cylinder gasoline engine UIT-85 with hydrogen additives up to 6% of the mass of fuel. The article shows the influence of hydrogen addition on the average velocity propagation of the flame front in the main combustion phase. The dependences of the turbulent propagation velocity of the flame front in the second combustion phase on the composition of the mixture and operating modes. The article shows the influence of the normal combustion rate on the average flame propagation velocity in the third combustion phase.

Pro-Life Arguments Against Infanticide and Why they are Not Convincing.

PubMed

Räsänen, Joona

2016-11-01

Alberto Giubilini and Francesca Minerva's controversial article 'After-Birth Abortion: Why Should the Baby Live?' has received a lot of criticism since its publishing. Part of the recent criticism has been made by pro-life philosopher Christopher Kaczor, who argues against infanticide in his updated book 'Ethics of Abortion'. Kaczor makes four arguments to show where Giubilini and Minerva's argument for permitting infanticide goes wrong. In this article I argue that Kaczor's arguments, and some similar arguments presented by other philosophers, are mistaken and cannot show Giubilini and Minerva's view to be flawed. I claim that if one wants to reject the permissibility of infanticide, one must find better arguments for doing so. © 2016 John Wiley & Sons Ltd.

Self-relation of adolescents in a family with a step-father.

PubMed

Belogai, Ksenia N

2010-11-01

This article represents an empirical study of adolescent's self-relation in a family where the mother has re-married. In many studies self-awareness and its functional aspect--self-relation--are selected as new stages in adolescence. The family is considered to be the most important factor in a child's and adolescent's personality development. Literature reviews on the specifics of a child's development in a family with a second marriage present some of the problems facing the parents and children in it. In the present article, problems of relations between children and parents are discussed. A principal finding of this report is that adolescents from families with a stepfather have a less flexible self-relation than adolescents from families with the biological father; to have a positive self-relation they need defence mechanisms. At the same time, analysis of adolescents' drawings shows that adolescents from families with a stepfather exclude themselves from the family system. In addition, the article discusses gender differences in self-relation in two types of families.

The presented article considers the influence of infiltrated outdoor air on the heat-shielding characteristics of the exterior walls of modern residential and public buildings. A review of the sources devoted to this problem confirmed its relevance at the present time, especially for high-rise buildings. The authors of the article analyzed the effect of longitudinal and transverse air infiltration on the heat-shielding characteristics of the outer wall of a 25-story building that was built in Samara. The results showed a significant reduction of the reduced resistance to the heat transfer of the outer wall when air is infiltrated through it. There are the results of full-scale examination of external walls to confirm the calculated data. Based on the results of the study carried out by the authors of the article, general recommendations on the internal finishing of the outer walls of high-rise buildings are given.

Introduction: Currently in Bosnia and Herzegovina there are 25 journals in the field of biomedicine, 6 of them are indexed in Medline/PubMed base (Medical Archives, Materia Socio-Medica, Acta Informatica Medica, Acta Medica Academica, Bosnian Journal of Basic Medical Sciences (BJBMS) and Medical Glasnik), and one (BJBMS) is indexed in Science Citation Index Expanded (SCIE)/Web of Science base. Aim: The aim of this study was to show the scope of work of the journals that were published by Academy of Medical Sciences of Bosnia and Herzegovina - Medical Archives, Materia Socio-Medica and Acta Informatica Medica. Material and Methods: The research presents a meta-analysis of three journals, or their issues, during the calendar year 2015 (retrospective and descriptive character). Results: During 2015 calendar year a total of 286 articles were published (in Medical Archives 104 (36.3%), in Materia Socio-Medica 99 (34.6%), and in Acta Informatica Medica 83 (29%)). Original articles are present in the highest number in all three journals (in Medical Archives 80.7%, in Materia Socio Medica 77.7%, and in Acta Informatica Medica 68.6%). In Medical Archives, 90.3% of the articles were related to the field of clinical medicine. In Materia Socio-Medica, the domain of clinical medicine and public health was the most represented. Preclinical areas are most frequent in Acta Informatica Medica. The period of 50-60 days for a decision on the admission of article is most common in all three journals, with trend of shortening of that period. Articles came from 19 countries, mostly from Bosnia and Herzegovina, then from Iran, Kosovo, Saudi Arabia and Greece. Conclusion: In Medical Archives original articles in the field of clinical medicine (usually internal and surgical disciplines) are most often present, and that is the case in last four years. The number of articles in Materia Socio-Medica and Acta Informatica Medica is growing from year to year. In Materia Socio-Medica there is a trend of growth of articles in the field of public health, while the most common articles in Acta Informatica Medica are about medical informatics. PMID:27041805

Phonotactic constraints: Implications for models of oral reading in Russian.

PubMed

Ulicheva, Anastasia; Coltheart, Max; Saunders, Steven; Perry, Conrad

2016-04-01

The present article investigates how phonotactic rules constrain oral reading in the Russian language. The pronunciation of letters in Russian is regular and consistent, but it is subject to substantial phonotactic influence: the position of a phoneme and its phonological context within a word can alter its pronunciation. In Part 1 of the article, we analyze the orthography-to-phonology and phonology-to-phonology (i.e., phonotactic) relationships in Russian monosyllabic words. In Part 2 of the article, we report empirical data from an oral word reading task that show an effect of phonotactic dependencies on skilled reading in Russian: humans are slower when reading words where letter-phoneme correspondences are highly constrained by phonotactic rules compared with those where there are few or no such constraints present. A further question of interest in this article is how computational models of oral reading deal with the phonotactics of the Russian language. To answer this question, in Part 3, we report simulations from the Russian dual-route cascaded model (DRC) and the Russian connectionist dual-process model (CDP++) and assess the performance of the 2 models by testing them against human data.

2015-01-01

This article examines developing trends within adolescent lesbian coming-out narratives in contemporary literary fiction and television shows. I argue that these texts, including ABC Family's Pretty Little Liars (2010-present), Madeleine George's The Difference Between You and Me (2012), A.S. King's Ask the Passengers (2012), and MTV's Faking It (2014-present), all experiment with the coming-out process in ways that complicate traditional narratives of adolescent queerness. By positioning their respective queer protagonists within broader queer and allied communities, these works articulate new complexities facing the young lesbian and her developing sexuality.

Proteus syndrome is a rare syndrome characterized by disproportionate overgrowth of limbs, multiple hamartomas, and vascular malformations. The cerebriform connective tissue nevi, also called cerebriform plantar hyperplasia, are present in most patients, and is the main characteristic of the syndrome. If present, even alone, they can be considered as a pathognomonic sign. This article reports a classic case of Proteus syndrome in a 2-year-old male patient who began to show a discrete asymmetry of the right hemibody in relation to the left one after birth, which increased over the months. He also showed cerebriform plantar hyperplasia and Port-wine stains, among other alterations. PMID:29166516

Doctor, Should I Use Computer Games to Prevent Dementia?

PubMed

O'Shea, Deirdre M; De Wit, Liselotte; Smith, Glenn E

2017-08-23

Commercial advertising of computerized "brain games" may result in clinicians being asked whether brain games prevent dementia. To address this question, we conducted a review of computerized cognitive training (CCT) interventions in older adults with Mild Cognitive Impairment (MCI). Studies were identified using a PubMed and PSYCinfo search for review articles. Within 11 review articles we identified 15 unique studies. Nine of these studies used commercially available "brain games" as their primary CCT intervention. Nine of 12 studies that examined the effect of CCT on episodic memory performance showed significant improvements in this domain. Furthermore, four of six studies that examined mood and or anxiety showed improvements in these domains following a CCT intervention. While more than double the amount of time was spent on the training that used commercially available "brain games" versus those designed by investigators, there were no differences in outcomes. Overall, it appears that "brain games" may modestly benefit aspects of cognition and aspects of mood in patients presenting with MCI. However, there is no direct evidence from the studies presented here that "brain games"/CCT can prevent dementia. We present recommendations to consider when discussing "brain games" with persons with MCI.

Modeling of Salmonella Contamination in the Pig Slaughterhouse.

Swart, A N; Evers, E G; Simons, R L L; Swanenburg, M

2016-03-01

In this article we present a model for Salmonella contamination of pig carcasses in the slaughterhouse. This model forms part of a larger QMRA (quantitative microbial risk assessment) on Salmonella in slaughter and breeder pigs, which uses a generic model framework that can be parameterized for European member states, to describe the entire chain from farm-to-consumption and the resultant human illness. We focus on model construction, giving mathematical formulae to describe Salmonella concentrations on individual pigs and slaughter equipment at different stages of the slaughter process. Variability among individual pigs and over slaughterhouses is incorporated using statistical distributions, and simulated by Monte Carlo iteration. We present the results over the various slaughter stages and show that such a framework is especially suitable to investigate the effect of various interventions. In this article we present the results of the slaughterhouse module for two case study member states. The model outcome represents an increase in average prevalence of Salmonella contamination and Salmonella numbers at dehairing and a decrease of Salmonella numbers at scalding. These results show good agreement when compared to several other QMRAs and microbiological studies. © 2016 Society for Risk Analysis.

PURPOSE The objective was to determine a link between the number of non-English language references in the bibliographies of publications in international pharmaceutical journals and the geographic origin of these publications. METHODS A systematic prospective analysis of 7 international pharmaceutical journals in 2005–2006. All research articles whom corresponding author was a pharmacist were included. For each article, were recorded: the geographic origin of the corresponding author (classified in: North America, Latin America, Oceania, Europe, Asia, others); the title of the journal; the number of non-English language references in the bibliography (classified in: Spanish, German, French, Portuguese, Dutch, Russian, Japanese, Chinese, others). RESULTS 1,568 articles were included, corresponding to 45,949 bibliographic references, of whom 542 where non-English references. North America is the geographic zone of the world with the lowest rate of non-English language references in bibliographies of published articles; significant differences appear between North America and Europe, Latin America and Asia. A sub-analysis by countries shows that United States, United Kingdom, Australia and China present a specific low rate of non-English language references. The two journals with the lowest rate of non-English language references in bibliographies of published articles are edited in the USA. CONCLUSIONS Despite some limitations, this study shows that pharmacists from regions where English language is the only or predominant language are refractory to include non-English language references in the bibliographies of their publications. The fundamental reasons of this restriction are not clear. PMID:19240258

Across academia and industry, text mining has become a popular strategy for keeping up with the rapid growth of the scientific literature. Text mining of the scientific literature has mostly been carried out on collections of abstracts, due to their availability. Here we present an analysis of 15 million English scientific full-text articles published during the period 1823-2016. We describe the development in article length and publication sub-topics during these nearly 250 years. We showcase the potential of text mining by extracting published protein-protein, disease-gene, and protein subcellular associations using a named entity recognition system, and quantitatively report on their accuracy using gold standard benchmark data sets. We subsequently compare the findings to corresponding results obtained on 16.5 million abstracts included in MEDLINE and show that text mining of full-text articles consistently outperforms using abstracts only.

Is herpes zoster vaccination likely to be cost-effective in Canada?

PubMed

Peden, Alexander D; Strobel, Stephenson B; Forget, Evelyn L

2014-05-30

To synthesize the current literature detailing the cost-effectiveness of the herpes zoster (HZ) vaccine, and to provide Canadian policy-makers with cost-effectiveness measurements in a Canadian context. This article builds on an existing systematic review of the HZ vaccine that offers a quality assessment of 11 recent articles. We first replicated this study, and then two assessors reviewed the articles and extracted information on vaccine effectiveness, cost of HZ, other modelling assumptions and QALY estimates. Then we transformed the results into a format useful for Canadian policy decisions. Results expressed in different currencies from different years were converted into 2012 Canadian dollars using Bank of Canada exchange rates and a Consumer Price Index deflator. Modelling assumptions that varied between studies were synthesized. We tabled the results for comparability. The Szucs systematic review presented a thorough methodological assessment of the relevant literature. However, the various studies presented results in a variety of currencies, and based their analyses on disparate methodological assumptions. Most of the current literature uses Markov chain models to estimate HZ prevalence. Cost assumptions, discount rate assumptions, assumptions about vaccine efficacy and waning and epidemiological assumptions drove variation in the outcomes. This article transforms the results into a table easily understood by policy-makers. The majority of the current literature shows that HZ vaccination is cost-effective at the price of $100,000 per QALY. Few studies showed that vaccination cost-effectiveness was higher than this threshold, and only under conservative assumptions. Cost-effectiveness was sensitive to vaccine price and discount rate.

Analyzing the presentation and the stigma of schizophrenia in French newspapers.

PubMed

Lampropoulos, Dimitrios; Wolman, Angelika; Apostolidis, Thémis

2017-12-01

It has been suggested that the stigmatizing presentation of people with schizophrenia by newspapers is an example of structural stigma. In this study, we explore how French newspapers contribute to the stigma of people with schizophrenia. All the articles of eight major newspapers (four national and four regional) that include the term schizophr* and that were published in 2015 were therefore analyzed using a coding scheme that we developed inductively. This analysis showed that among the identified themes, 40.4% of the articles used the term schizophrenia metaphorically and 28.3% referred to dangerousness. The first concerned mostly national newspapers, while the second were mostly published by regional newspapers. A more selective analysis was also carried out on these major themes in order to investigate how the "us" against "them" distinction is created and how negative stereotypes are associated with this distinction. In the case of the metaphorical use of the term, schizophrenia was presented as a "split personality" disorder and the label used in order to devalue the political opposition. Schizophrenia was presented either as a deterministic cause of dangerousness or as a potential cause of crime. In either case, the question of control was clearly present in these articles. These results are discussed in terms of the "us" against "them" distinction as a double process of stigmatization of people with schizophrenia and of reinforcement of one's own identity and security.

The scientific publications in anesthesiology research from East Asian authors have not been reported yet. The present study was designed to analyze the contribution of articles from East Asia to anesthesiology research. Articles published in 17 journals in anesthesiology originating from Japan, China, and South Korea from 2000 to 2009 were retrieved from the PubMed database and Web of Science. From 2000 to 2009, there were 3,076 articles published from East Asia. During this period, there were a notable decrease in publications from Japan and modest increases in publications from both China and South Korea. The average 5-year impact factor of the published articles was similar among the three regions, and China had the highest average number of citations to each article. Anesthesia & Analgesia published more articles than any other journal from all three regions. Our analysis showed that Japan was the most productive region in East Asia, but there was a notable decrease in publications from Japan in 2000-2009. The impact factor of the articles suggests similar levels of scholarship. Anesthesia & Analgesia was the most popular journal in East Asia.

The article presents an economic analysis and comparison of selected (district heating, natural gas, heat pump with renewable energy sources) methods for the preparation of domestic hot water in a building with low energy demand. In buildings of this type increased demand of energy for domestic hot water preparation in relation to the total energy demand can be observed. As a result, the proposed solutions allow to further lower energy demand by using the renewable energy sources. This article presents the results of numerical analysis and calculations performed mainly in MATLAB software, based on typical meteorological years. The results showed that system with heat pump and renewable energy sources Is comparable with district heating system.

Rare diseases, rare presentations: recognizing atypical inherited kidney disease phenotypes in the age of genomics.

PubMed

Ars, Elisabet; Torra, Roser

2017-10-01

A significant percentage of adults (10%) and children (20%) on renal replacement therapy have an inherited kidney disease (IKD). The new genomic era, ushered in by the next generation sequencing techniques, has contributed to the identification of new genes and facilitated the genetic diagnosis of the highly heterogeneous IKDs. Consequently, it has also allowed the reclassification of diseases and has broadened the phenotypic spectrum of many classical IKDs. Various genetic, epigenetic and environmental factors may explain 'atypical' phenotypes. In this article, we examine different mechanisms that may contribute to phenotypic variability and also provide case examples that illustrate them. The aim of the article is to raise awareness, among nephrologists and geneticists, of rare presentations that IKDs may show, to facilitate diagnosis.

Comparison Of Methods Used In Cartography For The Skeletonisation Of Areal Objects

NASA Astrophysics Data System (ADS)

Szombara, Stanisław

2015-12-01

The article presents a method that would compare skeletonisation methods for areal objects. The skeleton of an areal object, being its linear representation, is used, among others, in cartographic visualisation. The method allows us to compare between any skeletonisation methods in terms of the deviations of distance differences between the skeleton of the object and its border from one side and the distortions of skeletonisation from another. In the article, 5 methods were compared: Voronoi diagrams, densified Voronoi diagrams, constrained Delaunay triangulation, Straight Skeleton and Medial Axis (Transform). The results of comparison were presented on the example of several areal objects. The comparison of the methods showed that in all the analysed objects the Medial Axis (Transform) gives the smallest distortion and deviation values, which allows us to recommend it.

Introducing Pre-university Students to Primary Scientific Literature Through Argumentation Analysis

NASA Astrophysics Data System (ADS)

Koeneman, Marcel; Goedhart, Martin; Ossevoort, Miriam

2013-10-01

Primary scientific literature is one of the most important means of communication in science, written for peers in the scientific community. Primary literature provides an authentic context for showing students how scientists support their claims. Several teaching strategies have been proposed using (adapted) scientific publications, some for secondary education, but none of these strategies focused specifically on scientific argumentation. The purpose of this study is to evaluate a strategy for teaching pre-university students to read unadapted primary scientific literature, translated into students' native language, based on a new argumentation analysis framework. This framework encompasses seven types of argumentative elements: motive, objective, main conclusion, implication, support, counterargument and refutation. During the intervention, students studied two research articles. We monitored students' reading comprehension and their opinion on the articles and activities. After the intervention, we measured students' ability to identify the argumentative elements in a third unadapted and translated research article. The presented framework enabled students to analyse the article by identifying the motive, objective, main conclusion and implication and part of the supports. Students stated that they found these activities useful. Most students understood the text on paragraph level and were able to read the article with some help for its vocabulary. We suggest that primary scientific literature has the potential to show students important aspects of the scientific process and to learn scientific vocabulary in an authentic context.

Fluid flow through a high cell density fluidized-bed during centrifugal bioreactor culture.

Detzel, Christopher J; Van Wie, Bernard J; Ivory, Cornelius F

2010-01-01

An increasing demand for products such as tissues, proteins, and antibodies from mammalian cell suspension cultures is driving interest in increasing production through high-cell density bioreactors. The centrifugal bioreactor (CCBR) retains cells by balancing settling forces with surface drag forces due to medium throughput and is capable of maintaining cell densities above 10(8) cells/mL. This article builds on a previous study where the fluid mechanics of an empty CCBR were investigated showing fluid flow is nonuniform and dominated by Coriolis forces, raising concerns about nutrient and cell distribution. In this article, we demonstrate that the previously reported Coriolis forces are still present in the CCBR, but masked by the presence of cells. Experimental dye injection observations during culture of 15 microm hybridoma cells show a continual uniform darkening of the cell bed, indicating the region of the reactor containing cells is well mixed. Simulation results also indicate the cell bed is well mixed during culture of mammalian cells ranging in size from 10 to 20 microm. However, simulations also allow for a slight concentration gradient to be identified and attributed to Coriolis forces. Experimental results show cell density increases from 0.16 to 0.26 when centrifugal force is doubled by increasing RPM from 650 to 920 at a constant inlet velocity of 6.5 cm/s; an effect also observed in the simulation. Results presented in this article indicate cells maintained in the CCBR behave as a high-density fluidized bed of cells providing a homogeneous environment to ensure optimal growth conditions.

Metal-promoted titania photocatalysis for destruction of nitrates and organics from aqueous environments.

PubMed

Anderson, James A

2018-01-13

This review article provides an overview of activities in the rapidly developing field of water purification via photocatalytic methods and focuses on the removal of nitrate ions with simultaneous removal of the hole scavenger. Many of the issues associated with provision of potable water in the developing world may be resolved by the use of simple physical methodologies such as filtration. However, many of the issues associated with water purity in the developed world involve complex, stable molecules present at low concentrations that are nonetheless capable of producing toxic effects in plants and animals and that require more demanding removal technologies. Photocatalytic methods can be operated remotely and often show minimal production of undesired side products. Titania alone shows limitations, not only in terms of the slow rate of photoreduction of nitrate but also in terms of selectivity and the need to employ radiation in the UV region due to the magnitude of the band gap. Key challenges may be defined as: reducing the band gap/increasing absorption in the visible region, enhancing the adsorption capacity/access to the surface sites and reducing the rate of hole/electron recombination. The present article will focus on the use of titania-based materials that involve metal co-catalysts for nitrate reduction.This article is part of a discussion meeting issue 'Providing sustainable catalytic solutions for a rapidly changing world'. © 2017 The Author(s).

Every company must ensure that the production process proceeds without interferences. Within this article, the author uses the term "interferences" in reference to unplanned stoppages caused by breakdowns. Unfortunately, usually due to machine operators' mistakes, machines break, which causes stoppages thus generating additional costs for the company. This article shows a cause and effect analysis of a breakdown in a production process. The FMEA as well as quality management tools: the Ishikawa diagram and Pareto chart were used for the analysis. Correction measures were presented which allowed for a significant reduction in the number of stoppages caused by breakdowns.

The purposes of this bibliography are to present an overview of the published literature on equity in health and to summarize key articles relevant to the mission of the International Society for Equity in Health (ISEqH). The intent is to show the directions being taken in health equity research including theories, methods, and interventions to understand the genesis of inequities and their remediation. Therefore, the bibliography includes articles from the health equity literature that focus on mechanisms by which inequities in health arise and approaches to reducing them where and when they exist.

Food Systems and Public Health Disparities

PubMed Central

Neff, Roni A.; Palmer, Anne M.; Mckenzie, Shawn E.; Lawrence, Robert S.

2009-01-01

The United States has set a national goal to eliminate health disparities. This article emphasizes the importance of food systems in generating and exacerbating health disparities in the United States and suggests avenues for reducing them. It presents a conceptual model showing how broad food system conditions interplay with community food environments—and how these relationships are filtered and refracted through prisms of social disparities to generate and exacerbate health disparities. Interactions with demand factors in the social environment are described. The article also highlights the separate food systems pathway to health disparities via environmental and occupational health effects of agriculture. PMID:23173027

2015-01-01

This article aims to show the identity of “CPL-active simple organic molecules” as a new concept in Organic Chemistry due to the potential interest of these molecules, as availed by the exponentially growing number of research articles related to them. In particular, it describes and highlights the interest and difficulty in developing chiral simple (small and nonaggregated) organic molecules able to emit left- or right-circularly polarized light efficiently, the efforts realized up to now to reach this challenging objective, and the most significant milestones achieved to date. General guidelines for the preparation of these interesting molecules are also presented. PMID:26136234

Additively manufactured Ti-6Al-4V implants were biofunctionalized using plasma electrolytic oxidation. At various time points during this process scanning electron microscopy imaging was performed to analyze the surface morphology (van Hengel et al., 2017) [1]. This data shows the changes in surface morphology during plasma electrolytic oxidation. Data presented in this article are related to the research article "Selective laser melting porous metallic implants with immobilized silver nanoparticles kill and prevent biofilm formation by methicillin-resistant Staphylococcus aureus" (van Hengel et al., 2017) [1].

Towards a standard design model for quad-rotors: A review of current models, their accuracy and a novel simplified model

NASA Astrophysics Data System (ADS)

Amezquita-Brooks, Luis; Liceaga-Castro, Eduardo; Gonzalez-Sanchez, Mario; Garcia-Salazar, Octavio; Martinez-Vazquez, Daniel

2017-11-01

Applications based on quad-rotor-vehicles (QRV) are becoming increasingly wide-spread. Many of these applications require accurate mathematical representations for control design, simulation and estimation. However, there is no consensus on a standardized model for these purposes. In this article a review of the most common elements included in QRV models reported in the literature is presented. This survey shows that some elements are recurrent for typical non-aerobatic QRV applications; in particular, for control design and high-performance simulation. By synthesising the common features of the reviewed models a standard generic model SGM is proposed. The SGM is cast as a typical state-space model without memory-less transformations, a structure which is useful for simulation and controller design. The survey also shows that many QRV applications use simplified representations, which may be considered simplifications of the SGM here proposed. In order to assess the effectiveness of the simplified models, a comprehensive comparison based on digital simulations is presented. With this comparison, it is possible to determine the accuracy of each model under particular operating ranges. Such information is useful for the selection of a model according to a particular application. In addition to the models found in the literature, in this article a novel simplified model is derived. The main characteristics of this model are that its inner dynamics are linear, it has low complexity and it has a high level of accuracy in all the studied operating ranges, a characteristic found only in more complex representations. To complement the article the main elements of the SGM are evaluated with the aid of experimental data and the computational complexity of all surveyed models is briefly analysed. Finally, the article presents a discussion on how the structural characteristics of the models are useful to suggest particular QRV control structures.

[Changes in nursing administration in supporting transplantation in Brazil].

PubMed

Cintra, Vivian; Sanna, Maria Cristina

2005-01-01

This historical and bibliographic study aimed to understand how Nursing was organized to support care in transplantation. The HISA, LILACS, BDENF, PERIENF and DEDALUS databases were consulted, and thirteen references were found, ten of which were scientific articles, two were master's dissertations and one was a doctoral thesis. The span of time chosen for study ranges from the date of the first kidney transplant in Brazil (1965), to the date of publication of the last scientific article found in the databases mentioned above (2003). After reading these articles, the ones that were similar in topic were grouped together, thus creating the thematic axis for the presentation of the results. The results showed that the Nursing profession has played an important and active role in transplants ever since the first procedure in 1965.

A 60-year-old Nigerian man, who had lived in Europe for 30 years but had returned home frequently, presented with right frontalis muscle weakness and right ulnar nerve palsy, without skin lesions. Neurophysiology showed a generalised neuropathy with demyelinating features. Blood tests were positive for HIV, with a normal CD4 count. There was nerve thickening both clinically and on MRI. Nerve biopsy showed chronic endoneuritis and perineuritis (indicating leprosy) without visible mycobacteria. His neuropathy continued to deteriorate (lepra reaction) before starting treatment with WHO multidrug therapy, highly active antiretroviral therapy and corticosteroids. There are 10 new cases of leprosy diagnosed annually in the UK. Coinfection with HIV is rare but paradoxically does not usually adversely affect the outcome of leprosy or change treatment. However, permanent nerve damage in leprosy is common despite optimal therapy. Leprosy should be considered in patients from endemic areas who present with mononeuritis multiplex. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

When young adults are questioned about where they gain their knowledge of HIV, overwhelmingly popular media (including television) is reported. Thus, the goal of this article is to question how media is used to educate and influence young people's present perceptions of HIV/AIDS. Narrative analysis of popular prime time shows was used focusing on the story lines and characters used to introduce the topic, as well as the myths and facts about HIV. Results presented provide researchers a clearer insight to how popular shows discuss HIV/AIDS while also highlighting the ways Social Cognitive Theory can still be utilized.

The purpose of this article is to present the first chest radiographic and CT descriptions of organizing pneumonia in response to smoking synthetic marijuana. Chest radiographs showed a diffuse miliary-micronodular pattern. Chest CT images showed diffuse centrilobular nodules and tree-in-bud pattern and a histopathologic pattern of organizing pneumonia with or without patchy acute alveolar damage. This distinct imaging pattern should alert radiologists to include synthetic marijuana abuse in the differential diagnosis.

The present paper proposes two methods of calculating components of the dose absorbed by the human body after exposure to a mixed neutron and gamma radiation field. The article presents a novel approach to replace the common iterative method in its analytical form, thus reducing the calculation time. It also shows a possibility of estimating the neutron and gamma doses when their ratio in a mixed beam is not precisely known.

Temporary Thermocouple Attachment for Thermal/Vacuum Testing at Non-Extreme Temperatures - Test Results

NASA Technical Reports Server (NTRS)

Wright, Sarah E.; Ungar, Eugene K.

2017-01-01

Post-test examination and data analysis that followed a two week long vacuum test showed that numerous self-stick thermocouples became detached from the test article. The thermocouples were reattached with thermally conductive epoxy and the test was repeated to obtain the required data. Because the thermocouple detachment resulted in significant expense and rework, it was decided to investigate the temporary attachment methods used around NASA and to perform a test to assess their efficacy. The present work describes the testing that was performed in early and mid-2017. The test article and the temporary thermocouple attachment methods tested are described. During the first test, fully half of the thermocouples detached - although the detachment showed subtly in the data for some. The second test was performed to confirm the data from the first test and to investigate the effect of test article and thermocouple grounding. The results of the testing over temperatures ranging from -150 to 200degF are detailed and preliminary recommendations are made for temporary thermocouple attachment methods.

Campbell, Matthew Frederick; Owen, Kyle G.; Davidson, David F.

The purpose of this article is to explore the dependence of calculated postshock thermodynamic properties in shock tube experiments upon the vibrational state of the test gas and upon the uncertainties inherent to calculation inputs. This paper first offers a comparison between state variables calculated according to a Rankine–Hugoniot–equation-based algorithm, known as FROSH, and those derived from shock tube experiments on vibrationally nonequilibrated gases. It is shown that incorrect vibrational relaxation assumptions could lead to errors in temperature as large as 8% for 25% oxygen/argon mixtures at 3500 K. Following this demonstration, this article employs the algorithm to show themore » importance of correct vibrational equilibration assumptions, noting, for instance, that errors in temperature of up to about 2% at 3500 K may be generated for 10% nitrogen/argon mixtures if vibrational relaxation is not treated properly. Lastly, this article presents an extensive uncertainty analysis, showing that postshock temperatures can be calculated with root-of-sum-of-square errors of better than ±1% given sufficiently accurate experimentally measured input parameters.« less

The aim of the present review was to systematically present the clinicopathological data of desmoplastic ameloblastoma (DA) from articles published in the literature. A comprehensive search of the databases (PubMed, Medline, SCOPUS, Web of Science, and Google Scholar) for published articles on DA was conducted. A total of 238 cases were identified and analyzed from 76 published papers. DA showed a slight male predilection (male: female=1.07:1) with a predominance in the fourth and fifth decades of life. Mandibular involvement (52.55%) was most commonly seen with a marked tendency for the anterior region (mandible: 40.9%, maxilla: 48.07%). The size of the lesion ranged from .5 cm to 20.4 cm, with the majority of cases measuring more than 3 cm in size (53.84%). Radiologically, most of the lesions presented mixed radiolucency and radiopacity (62%), and root resorption was observed in only seven cases. The majority of the lesions showed ill-defined margins upon radiographic examination (65.78%). Most of the cases were treated with resection (78.57%), and five of the 10 recurrent cases were treated by enucleation/curettage. DA is characterized by the unique presentation of clinicopathological parameters. It is not possible to comment on its aggressive/recurrent nature and best treatment modality due to inadequate follow-up data. © 2017 John Wiley & Sons Australia, Ltd.

Although several studies have examined the contribution of specific countries, journals, and authors in different scientific disciplines, little is known about the contribution of different world countries, journals, and authors to scientific research in the field of "Spirituality, religion, and health" (S/R). The present study aims to analyze the last 15 years of research in the field of spirituality and religiousness (S/R) through a bibliometric analysis. Using the Pubmed database, we retrieved all articles related to S/R field for the period 1999-2013. We then estimated the total number of publications, number of articles published per year, articles published per country, journals with most publications in S/R field, most productive authors, and most used keywords. We found a growth of publications in the last years, most from the United States and the United Kingdom and published in the English language. Noteworthy, some developing countries such as India, Brazil, Israel, and Iran are at higher positions in this list. The S/R articles were published in journals embracing all fields of research, including high impact journals. In the present study, we took a closer look at the field of "Spirituality, religion, and health," showing that this field of research has been constantly growing and consolidating in the scientific community.

2015-01-01

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.

The data presented in this article are related to the research article entitled "Cyclic Shear behavior of conventional and harmonic structure-designed Ti-25Nb-25Zr β-titanium alloy: Back-stress hardening and twinning inhibition" (Dirras et al., 2017) [1]. The datasheet describes the methods used to fabricate two β-titanium alloys having conventional microstructure and so-called harmonic structure (HS) design via a powder metallurgy route, namely the spark plasma sintering (SPS) route. The data show the as-processed unconsolidated powder microstructures as well as the post-SPS ones. The data illustrate the mechanical response under cyclic shear loading of consolidated alloy specimens. The data show how electron back scattering diffraction(EBSD) method is used to clearly identify induced deformation features in the case of the conventional alloy.

Comparison of concepts in easy-to-use methods for MSD risk assessment.

2014-05-01

This article presents a comparative analysis of easy-to-use methods for assessing musculoskeletal load and the risk for developing musculoskeletal disorders. In all such methods, assessment of load consists in defining input data, the procedure and the system of assessment. This article shows what assessment steps the methods have in common; it also shows how those methods differ in each step. In addition, the methods are grouped according to their characteristic features. The conclusion is that the concepts of assessing risk in different methods can be used to develop solutions leading to a comprehensive method appropriate for all work tasks and all parts of the body. However, studies are necessary to verify the accepted premises and to introduce some standardization that would make consolidation possible. Copyright © 2013 Elsevier Ltd and The Ergonomics Society.

Retracted articles in surgery journals. What are surgeons doing wrong?

PubMed

Cassão, Bruna Dell'Acqua; Herbella, Fernando A M; Schlottmann, Francisco; Patti, Marco G

2018-06-01

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.

Health economic evaluation research plays an important role in selecting cost-effective interventions. The purpose of this study was to assess the quality of published articles in Iranian journals related to economic evaluation in health care programs based on Drummond's checklist in terms of numbers, features, and quality. In the present review study, published articles (Persian and English) in Iranian journals related to economic evaluation in health care programs were searched using electronic databases. In addition, the methodological quality of articles' structure was analyzed by Drummond's standard checklist. Based on the inclusion criteria, the search of databases resulted in 27 articles that fully covered economic evaluation in health care programs. A review of articles in accordance with Drummond's criteria showed that the majority of studies had flaws. The most common methodological weakness in the articles was in terms of cost calculation and valuation. Considering such methodological faults in these studies, it is anticipated that these studies would not provide an appropriate feedback to policy makers to allocate health care resources correctly and select suitable cost-effective interventions. Therefore, researchers are required to comply with the standard guidelines in order to better execute and report on economic evaluation studies.

Jung's evolving views of Nazi Germany: from 1936 to the end of World War II.

PubMed

Schoenl, William

2014-04-01

This article first shows Jung's evolving views of Nazi Germany from 1936 to the beginning of World War II. In a lecture at the Tavistock Clinic, London, in October 1936, he made his strongest and most negative statements to that date about Nazi Germany. While in Berlin in September 1937 for lectures to the Jung Gesellschaft, his observations of Hitler at a military parade led him to conclude that should the catastrophe of war come it would be far more and bloodier than he had previously supposed. After the Sudetenland Crisis in Fall 1938, Jung in interviews made stronger comments on Hitler and Nazi Germany. The article shows how strongly anti-Nazi Jung's views were in relation to events during World War II such as Nazi Germany's invasion of Poland, the fall of France, the bombings of Britain, the U.S. entry into the War, and Allied troops advancing into Germany. Schoenl and Peck, 'An Answer to the Question: Was Jung, for a Time, a "Nazi Sympathizer" or Not?' (2012) demonstrated how his views of Nazi Germany changed from 1933 to March 1936. The present article shows how his views evolved from 1936 to the War's end in 1945. © 2014, The Society of Analytical Psychology.

Whetstone Typology: Or the First Shipwreck of Turid Fiskarbekk and Marine Archaeologists Who Had to Think Again

NASA Astrophysics Data System (ADS)

Nymoen, Pål

2009-12-01

Finds from the Viking period, the middle ages and from more recent historical trading places and towns in northern Europe show that the export of whetstones from Eidsborg in the Telemark district of southern Norway has a history of more than 1,000 years. The water-based route from the quarry area, 600 m above sea level, to the nearest shipping port consists of 120 km of lakes, rivers and portages. This article takes up the export history in the light of a recently discovered cargo of whetstones found in Flåvann, Telemark. The history of the recovery of the find shows that the cargo examined most probably leads to an incident in the 1820s and, to a woman named Turid Fiskarbekk. The find leads to a wider perspective, more specific to the life of Turid Fiskarbekk. Therefore the article presents a side-story about her, where the intention is to show how integrating a gender perspective in maritime archaeology makes new knowledge possible.

Glutathione S - transferases class Pi and Mi and their significance in oncology.

Marchewka, Zofia; Piwowar, Agnieszka; Ruzik, Sylwia; Długosz, Anna

2017-06-19

In this article the current data, which shows that glutathione S-transferases (GST) class Pi and Mi are interesting and promising biomarkers in acute and chronic inflammatory processes as well as in the oncology, were presented based on the review of the latest experimental and clinical studies. The article shows their characteristics, functions and participation (direct - GST Pi, indirect - GST Mi) in the regulation of signaling pathways of JNK kinases, which are involved in cell differentiation. Overexpression of glutathione S-transferases class Pi and Mi in many cancer cells plays a key role in cancer treatment, making them resistant to chemotherapy. GST isoenzymes are involved in the metabolism of various types of xenobiotics and endogenous substrates, so their altered expression in cancer tissues as well as in serum and urine could be an important potential marker of the cancer and an indicator of oxidative stress. The study shows the role of glutathione S-transferases in redox homeostasis of tumor cells and in the mechanism of resistance to anticancer drugs.

Prevalence of Recommendations Made Within Dental Research Articles Using Uncontrolled Intervention or Observational Study Designs.

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.

Proton Pump Inhibitors: Risk for Myopathy?

PubMed

Colmenares, Evan W; Pappas, Ashley L

2017-01-01

The purpose of this article is to describe the relationship between proton pump inhibitors (PPIs) and symptoms of myopathy based on case reports. A literature search was conducted in PubMed (1946 to June 2016) using MeSH terms proton pump inhibitors, omeprazole, esomeprazole, lansoprazole, dexlansoprazole, rabeprazole, pantoprazole, and muscular diseases. Additionally, a search was conducted in ToxNet and EMBASE using similar search criteria. The resulting articles were scanned to assess relevance to the review. Bibliographies of all relevant articles were evaluated for additional sources; 26 articles resulted from the search of PubMed, ToxNet, and EMBASE; articles that involved medications typically considered to have myalgia-like side effects (eg, statins), or included patients who presented with a confounding disease state (eg, Guillain-Barré) were excluded. In total, 11 case reports as well as a review of an adverse event reporting database that included 292 cases were evaluated. Association of PPI use and myopathy symptoms does not have a clear etiology. Overall, the available published data do not show a high risk of myopathy with PPI use but should be considered if a patient presents with myopathy symptoms and concurrent PPI use. A limited body of published data suggests that PPI use has been associated with myopathy-like symptoms without long-term effects following discontinuation. Although myopathy is a rare adverse effect observed with PPIs, it can be a serious side effect to be considered when starting a patient on acid suppression therapy.

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

PubMed

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.

Conclusions: Original articles in endodontic publication from different universities in India have considerably increased, showing that research is becoming more important. PMID:27795645

Pursuing Pleasures of Productivity: University Students' Use of Prescription Stimulants for Enhancement and the Moral Uncertainty of Making Work Fun.

PubMed

Petersen, Margit Anne; Nørgaard, Lotte Stig; Traulsen, Janine M

2015-12-01

This article presents ethnographic data on the use of prescription stimulants for enhancement purposes by university students in New York City. The study shows that students find stimulants a helpful tool in preventing procrastination, particularly in relation to feeling disinterested, overloaded, or insecure. Using stimulants, students seek pleasure in the study situation, for example, to get rid of unpleasant states of mind or intensify an already existing excitement. The article illustrates the notion that enhancement strategies do not only concern productivity in the quantitative sense of bettering results, performances, and opportunities. Students also measure their own success in terms of the qualitative experience of working hard. The article further argues that taking an ethnographic approach facilitates the study of norms in the making, as students experience moral uncertainty-not because they improve study skills and results-but because they enhance the study experience, making work fun. The article thereby seeks to nuance simplistic neoliberal ideas of personhood.

Early detection of response to treatment is critically important in gastrointestinal stromal tumors (GIST). Therefore, the present systematic review and meta-analysis assessed the value of (18) f-fluorodeoxyglucose positron emission tomography ((18) FDG-PET) on prediction of therapeutic response of GIST patients to systemic treatments. The literature search was conducted using PubMed, SCOPUS, Cochrane, and Google Scholar databases, and review article references. Eligible articles were defined as studies included confirmed GIST patients who underwent (18) FDG-PET as well as assessing the screening role of it. Finally, 21 relevant articles were included. The analysis showed the pooled sensitivity and specificity of 18FDG-PET in evaluation of response to treatment of GIST patient were 0.90 (95% CI: 0.85-0.94; I(2)  = 52.59, P = 0.001) and 0.62 (95% CI: 0.49-0.75; I(2)  = 69.7, P = 0.001), respectively. In addition, the pooled prognostic odds ratio of (18) FDG-PET for was 14.99 (95% CI, 6.42-34.99; I(2)  = 100.0, P < 0.001). The Meta regression showed that sensitivity of (18) FDG-PET was higher if the sample size of study was equal or more than 30 cases (sensitivity = 0.93; 95% CI: 0.89-0.97), when using PET/CT (sensitivity = 0.92; 95% CI: 0.89-0.97), and self-design criteria (sensitivity = 0.93; 95% CI: 0.87-1.0). The present meta-analysis showed (18) FDG-PET has a significant value in predicting treatment response in GIST patients. © 2015 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

Although the cochlear implant has been widely acknowledged as the most successful neural prosthesis, only a fraction of hearing-impaired people who can potentially benefit from a cochlear implant have actually received one due to its limited awareness, accessibility, and affordability. To help overcome these limitations, a 26-electrode cochlear implant has been developed to receive China's Food and Drug Administration (CFDA) approval in 2011 and Conformité Européenne (CE) Marking in 2012. The present article describes design philosophy, system specification, and technical verification of the Nurotron device, which includes advanced digital signal processing and 4 current sources with multiple amplitude resolutions that not only are compatible with perceptual capability but also allow interleaved or simultaneous stimulation. The article also presents 3-year longitudinal evaluation data from 60 human subjects who have received the Nurotron device. The objective measures show that electrode impedance decreased within the first month of device use, but was stable until a slight increase at the end of two years. The subjective loudness measures show that electric stimulation threshold was stable while the maximal comfort level increased over the 3 years. Mandarin sentence recognition increased from the pre-surgical 0%-correct score to a plateau of about 80% correct with 6-month use of the device. Both indirect and direct comparisons indicate indistinguishable performance differences between the Nurotron system and other commercially available devices. The present 26-electrode cochlear implant has already helped to lower the price of cochlear implantation in China and will likely contribute to increased cochlear implant access and success in the rest of the world.

Symbol signal-to-noise ratio loss in square-wave subcarrier downconversion

NASA Technical Reports Server (NTRS)

Feria, Y.; Statman, J.

1993-01-01

This article presents the simulated results of the signal-to-noise ratio (SNR) loss in the process of a square-wave subcarrier down conversion. In a previous article, the SNR degradation was evaluated at the output of the down converter based on the signal and noise power change. Unlike in the previous article, the SNR loss is defined here as the difference between the actual and theoretical symbol SNR's for the same symbol-error rate at the output of the symbol matched filter. The results show that an average SNR loss of 0.3 dB can be achieved with tenth-order infinite impulse response (IIR) filters. This loss is a 0.2-dB increase over the SNR degradation in the previous analysis where neither the signal distortion nor the symbol detector was considered.

Emotion Recognition - the need for a complete analysis of the phenomenon of expression formation

NASA Astrophysics Data System (ADS)

Bobkowska, Katarzyna; Przyborski, Marek; Skorupka, Dariusz

2018-01-01

This article shows how complex emotions are. This has been proven by the analysis of the changes that occur on the face. The authors present the problem of image analysis for the purpose of identifying emotions. In addition, they point out the importance of recording the phenomenon of the development of emotions on the human face with the use of high-speed cameras, which allows the detection of micro expression. The work that was prepared for this article was based on analyzing the parallax pair correlation coefficients for specific faces. In the article authors proposed to divide the facial image into 8 characteristic segments. With this approach, it was confirmed that at different moments of emotion the pace of expression and the maximum change characteristic of a particular emotion, for each part of the face is different.

The disasters of war in Darfur, 1950-2004.

PubMed

Reyna, Stephen P

2010-01-01

This article investigates the conflict that had been developing since the 1950s in Darfur and which in 2003 and 2004 burst into intense warfare. A 'complex-structuring of violence' standpoint explains the warfare. The argument is organised in two parts. The first section formulates the position by introducing Darfur, next evaluating the prevailing barbarisation perspective's attempts to explicate Darfur warring and, finally, formally presenting the complex structuring standpoint. The second section offers evidence bearing upon this standpoint. This involves information showing that four interrelated structural realms form a causal complex producing the violence. The article ends with discussion of the US government's role in Darfurian disasters of war.

Bagley, Sue

2012-03-01

Emergency nurse practitioners should be prepared to prescribe post-exposure prophylaxis for sexual exposure (PEPSE) to people who may have been exposed to HIV, even where the number of such presentations is small. As this article makes clear, nurse prescribers require a sound knowledge of the drugs recommended in PEPSE protocols, and of their side effects, to relieve patients' anxiety and inform them about safe sexual practice. The article offers a case study and reflection to show that patients, particularly those who may have been exposed to HIV, who have been given the information they want are more likely to complete their courses of treatment.

de la Torre Díez, Isabel; Garcia-Zapirain, Begoña; Méndez-Zorrilla, Amaia; López-Coronado, Miguel

2016-07-01

In developed countries heart failure is one of the most important causes of death, followed closely by strokes and other cerebrovascular diseases. It is one of the major healthcare issues in terms of increasing number of patients, rate of hospitalizations and costs. The main aim of this paper is to present telemedicine applications for monitoring and follow-up of heart failure and to show how these systems can help reduce costs of administering heart failure. The search for e-health applications and systems in the field of telemonitoring of heart failure was pursued in IEEE Xplore, Science Direct, PubMed and Scopus systems between 2005 and the present time. This search was conducted between May and June 2015, and the articles deemed to be of most interest about treatment, prevention, self-empowerment and stabilization of patients were selected. Over 100 articles about telemonitoring of heart failure have been found in the literature reviewed since 2005, although the most interesting ones have been selected from the scientific standpoint. Many of them show that telemonitoring of patients with a high risk of heart failure is a measure that might help to reduce the risk of suffering from the disease. Following the review conducted, in can be stated that via the research articles analysed that telemonitoring systems can help to reduce the costs of administering heart failure and result in less re-hospitalization of patients.

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.

Reed, Jennifer

2010-01-01

This article argues that Rachel Maddow has become one of a growing number of new public lesbians. This is a subject position that makes no secret of or apology for lesbian identity. Nor does it seek to make explicit political claims for liberation or separation. Maddow uses this subject position as host of her own cable news show, The Rachel Maddow Show, combined with her presence in other media, where she presents as a butch lesbian and comments on her more conservative look on her television show, to create a lesbian presence that disrupts heteronormativity, offers alternatives to heterogender, and in particular as a news show, tells a more inclusive liberal humanist story.

Misuse of odds ratios in obesity literature: an empirical analysis of published studies.

PubMed

Tajeu, Gabriel S; Sen, Bisakha; Allison, David B; Menachemi, Nir

2012-08-01

Odds ratios (ORs) are widely used in scientific research to demonstrate the associations between outcome variables and covariates (risk factors) of interest, and are often described in language suitable for risks or probabilities, but odds and probabilities are related, not equivalent. In situations where the outcome is not rare (e.g., obesity), ORs no longer approximate the relative risk ratio (RR) and may be misinterpreted. Our study examines the extent of misinterpretation of ORs in Obesity and International Journal of Obesity. We reviewed all 2010 issues of these journals to identify all articles that presented ORs. Included articles were then primarily reviewed for correct presentation and interpretation of ORs; and secondarily reviewed for article characteristics that may have been associated with how ORs are presented and interpreted. Of the 855 articles examined, 62 (7.3%) presented ORs. ORs were presented incorrectly in 23.2% of these articles. Clinical articles were more likely to present ORs correctly than social science or basic science articles. Studies with outcome variables that had higher relative prevalence were less likely to present ORs correctly. Overall, almost one-quarter of the studies presenting ORs in two leading journals on obesity misinterpreted them. Furthermore, even when researchers present ORs correctly, the lay media may misinterpret them as relative RRs. Therefore, we suggest that when the magnitude of associations is of interest, researchers should carefully and accurately present interpretable measures of association--including RRs and risk differences--to minimize confusion and misrepresentation of research results.

Background: This systematic review aimed to extract recommendations from expert opinion articles on how to give a medical research presentation on a scientific conference and to determine whether the experts agree on what makes an effective or poor presentation. Methods: Presentation-related terms were searched within article titles listed in PubMed, restricting the search to English-language articles published from January 1975 to July 2015. Recommendations were extracted from the articles, grouped by content, and analyzed for frequency. Ninety-one articles were included. Among 679 different recommendations, 29 were given in more than 20% of articles each. The five most frequent recommendations were to keep slides simple, adjust the talk to the audience, rehearse, not read the talk from slides or a manuscript, and make eye contact. Results: No article gave advice that was the complete opposite of the 29 most frequent recommendations with the exception of whether a light or dark background should be used for slides. Conclusions: Researchers should comply with these widely accepted standards to be perceived as effective presenters.

Background: This systematic review aimed to extract recommendations from expert opinion articles on how to give a medical research presentation on a scientific conference and to determine whether the experts agree on what makes an effective or poor presentation. Methods: Presentation-related terms were searched within article titles listed in PubMed, restricting the search to English-language articles published from January 1975 to July 2015. Recommendations were extracted from the articles, grouped by content, and analyzed for frequency. Ninety-one articles were included. Among 679 different recommendations, 29 were given in more than 20% of articles each. The five most frequent recommendations were to keep slides simple, adjust the talk to the audience, rehearse, not read the talk from slides or a manuscript, and make eye contact. Results: No article gave advice that was the complete opposite of the 29 most frequent recommendations with the exception of whether a light or dark background should be used for slides. Conclusions: Researchers should comply with these widely accepted standards to be perceived as effective presenters. PMID:28293678

Chu, C. W.; Deng, L. Z.; Lv, B.

2015-07-01

Hole-doped cuprate high temperature superconductors have ushered in the modern era of high temperature superconductivity (HTS) and have continued to be at center stage in the field. Extensive studies have been made, many compounds discovered, voluminous data compiled, numerous models proposed, many review articles written, and various prototype devices made and tested with better performance than their nonsuperconducting counterparts. The field is indeed vast. We have therefore decided to focus on the major cuprate materials systems that have laid the foundation of HTS science and technology and present several simple scaling laws that show the systematic and universal simplicity amid the complexity of these material systems, while referring readers interested in the HTS physics and devices to the review articles. Developments in the field are mostly presented in chronological order, sometimes with anecdotes, in an attempt to share some of the moments of excitement and despair in the history of HTS with readers, especially the younger ones.

Coming out of the dark: content analysis of articles pertaining to gay, lesbian, and bisexual issues in couple and family therapy journals.

PubMed

2012-06-01

The present study seeks to extend previous research regarding literature related to gay, lesbian, and bisexual (GLB) issues published in couple and family therapy (CFT)-related journals by presenting the results from a content analysis of GLB studies in CFT-related journals from 1996 to 2010. Results of the analysis revealed a 238.8% increase in total GLB content published since the original review. Articles pertaining to therapy with GLB clients continue to represent the largest area of publication. With one exception, all surveyed journals showed an increase in the percentage of GLB content since the first study. Emerging areas of research include studies related to supervision and training, GLB mental health and substance use, and sexual minority adolescents. A movement away from deficit-based perspectives could open a new lens on family life. © 2012 American Association for Marriage and Family Therapy.

Clinical linguistics: its past, present and future.

PubMed

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.

Phylogenetic Trees and Networks Reduce to Phylogenies on Binary States: Does It Furnish an Explanation to the Robustness of Phylogenetic Trees against Lateral Transfers.

PubMed

Thuillard, Marc; Fraix-Burnet, Didier

2015-01-01

This article presents an innovative approach to phylogenies based on the reduction of multistate characters to binary-state characters. We show that the reduction to binary characters' approach can be applied to both character- and distance-based phylogenies and provides a unifying framework to explain simply and intuitively the similarities and differences between distance- and character-based phylogenies. Building on these results, this article gives a possible explanation on why phylogenetic trees obtained from a distance matrix or a set of characters are often quite reasonable despite lateral transfers of genetic material between taxa. In the presence of lateral transfers, outer planar networks furnish a better description of evolution than phylogenetic trees. We present a polynomial-time reconstruction algorithm for perfect outer planar networks with a fixed number of states, characters, and lateral transfers.

"Thinking-for-Writing": A Prolegomenon on Writing Signed Languages.

PubMed

Rosen, Russell S; Hartman, Maria C; Wang, Ye

2017-01-01

In his article in this American Annals of the Deaf special issue that also includes the present article, Grushkin argues that the writing difficulties of many deaf and hard of hearing children result primarily from the orthographic nature of the writing system; he proposes a new system based on features found in signed languages. In response, the present authors review the literature on D/HH children's writing difficulties, outline the main percepts of and assumptions about writing signed languages, discuss "thinking-for-writing" as a process in developing writing skills, offer research designs to test the effectiveness of writing signed language systems, and provide strategies for adopting "thinking-for-writing" in education. They conclude that until empirical studies show that writing signed languages effectively reflects writers' "thinking-for-writing," the alphabetic orthographic system of English should still be used, and ways should be found to teach D/HH children to use English writing to express their thoughts.

2013-01-01

Co-operation between different parties and effective safety management play an important role in ensuring safety in multiemployer worksites. This article reviews safety co-operation and factors complicating safety management in Finnish multiemployer manufacturing worksites. The paper focuses on the service providers' opinions; however, a comparison of the customers' views is also presented. The results show that safety-related co-operation between providers and customers is generally considered as successful but strongly dependent on the partner. Safety co-operation is provided through, e.g., training, orientation and risk analysis. Problems encountered include ensuring adequate communication, identifying hazards, co-ordinating work tasks and determining responsibilities. The providers and the customers encounter similar safety management problems. The results presented in this article can help companies to focus their efforts on the most problematic points of safety management and to avoid common pitfalls.

Although several methods exist for Adverse Drug events (ADE) detection due to past hospitalizations, a tool that could display those ADEs to the physicians does not exist yet. This article presents the ADE Scorecards, a Web tool that enables to screen past hospitalizations extracted from Electronic Health Records (EHR), using a set of ADE detection rules, presently rules discovered by data mining. The tool enables the physicians to (1) get contextualized statistics about the ADEs that happen in their medical department, (2) see the rules that are useful in their department, i.e. the rules that could have enabled to prevent those ADEs and (3) review in detail the ADE cases, through a comprehensive interface displaying the diagnoses, procedures, lab results, administered drugs and anonymized records. The article shows a demonstration of the tool through a use case.

To determine the characteristics and trends of the original articles published in two major American radiology journals, AJR American Journal of Roentgenology (AJR) and Radiology, between 2001 and 2010. This was a retrospective bibliometric analysis that did not involve human subjects and was exempt from institutional review board approval. All 6542 original articles published in AJR and Radiology between 2001 and 2010 were evaluated. The following information was abstracted from each article: radiologic subspecialty, radiologic technique used, type of research, sample size, study design, statistical analysis, study outcome, declared funding, number of authors, affiliation of the first author, and country of the first author. In addition, all the variables examined were presented along with the trend over time. The most common subspecialty of study was abdominal (1219 of 6542, 18.6%), followed by vascular/interventional (804 of 6542, 12.3%). A total of 3744 (57.2%) original articles used magnetic resonance (MR) imaging or computed tomography (CT), 5495 (84.1%) were clinical research articles, 3060 (46.8%) had sample size of more than 50, 4087 (62.5%) were retrospective, 4714 (72.1%) performed statistical analysis, 6225 (95.2%) showed positive study outcome, 4784 (73.1%) were not funded, 3942 (60.3%) had four to seven authors, and 5731 (87.6%) were written by the primary author who was from a department of radiology or radiology-related specialties. The United States published 45.5% (2975 of 6542) of the articles, followed by Japan (n = 525, 8.0%), Germany (n = 485, 7.4%), and South Korea (n = 455, 7.0%). In the time trend analysis, the following variables showed a significantly positive trend: cardiac subspecialty, CT and MR imaging as the radiologic techniques, type of research as other (nonbasic, nonclinical), sample size of more than 50, four to seven as the number of authors, medicine-related department of the first author, and South Korea and Italy as countries of the first author. On the other hand, pediatric subspecialty, combined (basic and clinical) type of research, and number of authors fewer than four showed a significantly negative trend. The bibliometric analysis of the AJR and Radiology journals with articles published between 2001 and 2010 revealed characteristics and trends of the current radiology research that may provide useful information to researchers and editorial staff in radiology. © RSNA, 2012

Year in review 2009: Critical Care--cardiac arrest, trauma and disasters.

PubMed

Metzger, Jeffery C; Eastman, Alexander L; Pepe, Paul E

2010-01-01

During 2009, Critical Care published nine papers on various aspects of resuscitation, prehospital medicine, trauma care and disaster response. One article demonstrated that children as young as 9 years of age can learn cardiopulmonary resuscitation (CPR) effectively, although, depending on their size, some may have difficulty performing it. Another paper showed that while there was a trend toward mild therapeutic hypothermia reducing S-100 levels, there was no statistically significant change. Another predictor study also showed a strong link between acute kidney injury and neurologic outcome while another article described a program in which kidneys were harvested from cardiac arrest patients and showed an 89% graft survival rate. One experimental investigation indicated that when a pump-less interventional lung assist device is present, leaving the device open (unclamped) while performing CPR has no harmful effects on mean arterial pressures and it may have positive effects on blood oxygenation and CO2 clearance. One other study, conducted in the prehospital environment, found that end-tidal CO2 could be useful in diagnosing pulmonary embolism. Three articles addressed disaster medicine, the first of which described a triage system for use during pandemic influenza that demonstrated high reliability in delineating patients with a good chance of survival from those likely to die. The other two studies, both drawn from the 2008 Sichuan earthquake experience, showed success in treating crush injured patients in an on-site tent ICU and, in the second case, how the epidemiology of earthquake injuries and related factors predicted mortality.

High Modulus Asphalt Concrete (HMAC) was introduced in Poland as a one of the solutions to the problem of rutting, type of deterioration common in the 1990s. After first encouraging trials in 2002 HMAC was widely used for heavily loaded national roads and motorways. However some concerns were raised about low-temperature cracking of HMAC. This was the main reason of the studies presented in this article were started. The article presents the comparison of performance of pavements constructed in typical contract conditions with the road bases made of HMAC and conventional asphalt concrete (AC). The field investigation was focused on the number of low-temperature cracks, bearing capacity (based on FWD test) of road sections localized in coldest region of Poland. Also load transfer efficiency of selected low-temperature cracks was assessed. FWD test confirmed lower deflections of pavements with HMAC and two times higher stiffness modulus of asphalt courses in comparison to pavements constructed with conventional AC mixtures. Relation of stiffness of asphalt layers and amount of low-temperature cracks showed that the higher stiffness modulus of asphalt layers could lead to increase of the number of low-temperature cracks. FWD test results showed that the load transfer efficiency of low-temperature cracks on pavements with HMAC presents very low values, very close to lack of load transfer. It was surprising as section with HMAC road base were aged from 2 to 5 years and presented very good bearing capacity.

Aim: A thesis is an important part of nursing graduate students’ education, which is also their first systematic and scientific attempt to learn the ABCs of research. Articles derived from theses are important for the dissemination of science and the improvement of nursing as a field. Therefore, it is the goal of the present research is to analyze the different aspects of nursing MSc theses and the number of published articles derived from them. Methods: This was a descriptive research carried out on 145 nursing MSc theses defended in Razi Faculty of Nursing and Midwifery in Kerman between 1990 and 2010. All of the extracted data were put into an Excel file (2007 version) followed by a data analysis. Results: The results of this study were then presented via the use of descriptive statistics and figures. The research findings showed that most of the theses used a descriptive or analytical-descriptive method, and 42% of them had patients as their participants. They were usually delivered on the subject of health care, and only 58 articles were extracted from the whole 145 theses. Conclusion: The process of writing nursing MSc theses and thesis research articles is improving gradually. However, there is a growing need for empirical and semi-empirical research to bridge the gap between theory and practice, which is also a major concern among nurses. PMID:25168988

As health organizations increasingly use the Internet to communicate medical information and advice (Shortliffe et al., 2000; World Health Organization, 2013), studying factors that affect health information processing and health-protective behaviors becomes extremely important. The present research applied the elaboration likelihood model of persuasion to explore the effects of media multitasking, polychronicity (preference for multitasking), and strength of health-related arguments on health-protective behavioral intentions. Participants read an online article about influenza that included strong and weak suggestions to engage in flu-preventive behaviors. In one condition, participants read the article and checked Facebook; in another condition, they were exposed only to the article. Participants expressed greater health-protective behavioral intentions in the media multitasking condition than in the control condition. Strong arguments were found to elicit more positive behavioral intentions than weak arguments. Moderate and high polychronics showed greater behavioral intentions than low polychronics when they read the article in the multitasking condition. The difference in intentions to follow strong and weak arguments decreased for moderate and high polychronics. The results of the present study suggest that health communication practitioners should account for not only media use situations in which individuals typically read about health online but also individual differences in information processing, which puts more emphasis on the strength of health-protective suggestions when targeting light multitaskers.

The aim of this article is to present a new and challenging model of treatment that combines two therapeutic interventions: hydrotherapy and Snoezelen or controlled multisensory stimulation. The combination of the two therapeutic approaches enhances the treatment effect by utilizing the unique characteristics of each approach. We believe that this combined model will further enhance each media to the benefit of the clients and create a new intervention approach. This article relates to a hydrotherapy swimming pool facility that has been established at the Williams Island Therapeutic Swimming and Recreation Center, Beit Issie Shapiro, Raanana in Israel, after acquiring many years of experience and gaining substantial knowledge both in the field of hydrotherapy and Snoezelen intervention. Beit Issie Shapiro is a non-profit community organization providing a range of services for children with developmental disabilities and their families. The organization provides direct services for nearly 6,000 children and adults each year. This article provides an overview of hydrotherapy and Snoezelen and presents a case study, which will demonstrate the new model of treatment and show how this new and innovative form of therapy can be used as a successful intervention. We believe it will open a path to enriching the repertoire of therapists helping people with special needs. This article is also addressed to researchers to provide ideas for further studies in this area.

Health economic evaluation research plays an important role in selecting cost-effective interventions. The purpose of this study was to assess the quality of published articles in Iranian journals related to economic evaluation in health care programs based on Drummond’s checklist in terms of numbers, features, and quality. In the present review study, published articles (Persian and English) in Iranian journals related to economic evaluation in health care programs were searched using electronic databases. In addition, the methodological quality of articles’ structure was analyzed by Drummond’s standard checklist. Based on the inclusion criteria, the search of databases resulted in 27 articles that fully covered economic evaluation in health care programs. A review of articles in accordance with Drummond’s criteria showed that the majority of studies had flaws. The most common methodological weakness in the articles was in terms of cost calculation and valuation. Considering such methodological faults in these studies, it is anticipated that these studies would not provide an appropriate feedback to policy makers to allocate health care resources correctly and select suitable cost-effective interventions. Therefore, researchers are required to comply with the standard guidelines in order to better execute and report on economic evaluation studies. PMID:29234174

Is there room in the DSM for consideration of deaf people?

PubMed

Lala, F J

1998-10-01

Recent changes to the Diagnostic and Statistical Manual of Mental Disorders, or DSM (4th ed., American Psychiatric Association, 1994), show recognition that cultural factors are relevant to assessment; thus, including specific information relevant to Deaf culture should help DSM users understand their deaf clients. For the present article, literature was surveyed on the psychological needs of the Deaf, and specifically how the Deaf views those needs. The review focused on four articles (Carver, 1995, 1997; Chapman, 1994; Dolnick, 1993). These articles suggest consensus on the thesis that the Deaf, as a minority culture, should provide information on Deaf culture to members of the helping professions. In addition to enhancing care providers' understanding, this would help society do a better job of including the Deaf in planning relevant to their needs. In particular, culturally deaf people should urge inclusion of relevant information about the Deaf in the next DSM revision.

Summary This article analyzes why adulteration became a key trope of the Indian drug market. Adulteration had a pervasive presence, being present in medical discourses, public opinion and debate, and the nationalist claim for government intervention. The article first situates the roots of adulteration in the composite nature of this market, which involved the availability of drugs of different potencies as well as the presence of multiple layers of manufacturers, agents, and distributors. It then shows that such a market witnessed the availability of drugs of diverse potency and strengths, which were understood as elements of adulteration in contemporary medical and official discourse. Although contemporary critics argued that the lack of government legislation and control allowed adulteration to sustain itself, this article establishes that the culture of the dispensation of drugs in India necessarily involved a multitude of manufacturer–retailers, bazaar traders, and medical professionals practicing a range of therapies.

A dynamic scheduling algorithm for singe-arm two-cluster tools with flexible processing times

NASA Astrophysics Data System (ADS)

Li, Xin; Fung, Richard Y. K.

2018-02-01

This article presents a dynamic algorithm for job scheduling in two-cluster tools producing multi-type wafers with flexible processing times. Flexible processing times mean that the actual times for processing wafers should be within given time intervals. The objective of the work is to minimize the completion time of the newly inserted wafer. To deal with this issue, a two-cluster tool is decomposed into three reduced single-cluster tools (RCTs) in a series based on a decomposition approach proposed in this article. For each single-cluster tool, a dynamic scheduling algorithm based on temporal constraints is developed to schedule the newly inserted wafer. Three experiments have been carried out to test the dynamic scheduling algorithm proposed, comparing with the results the 'earliest starting time' heuristic (EST) adopted in previous literature. The results show that the dynamic algorithm proposed in this article is effective and practical.

Multi-terminal pipe routing by Steiner minimal tree and particle swarm optimisation

NASA Astrophysics Data System (ADS)

Liu, Qiang; Wang, Chengen

2012-08-01

Computer-aided design of pipe routing is of fundamental importance for complex equipments' developments. In this article, non-rectilinear branch pipe routing with multiple terminals that can be formulated as a Euclidean Steiner Minimal Tree with Obstacles (ESMTO) problem is studied in the context of an aeroengine-integrated design engineering. Unlike the traditional methods that connect pipe terminals sequentially, this article presents a new branch pipe routing algorithm based on the Steiner tree theory. The article begins with a new algorithm for solving the ESMTO problem by using particle swarm optimisation (PSO), and then extends the method to the surface cases by using geodesics to meet the requirements of routing non-rectilinear pipes on the surfaces of aeroengines. Subsequently, the adaptive region strategy and the basic visibility graph method are adopted to increase the computation efficiency. Numeral computations show that the proposed routing algorithm can find satisfactory routing layouts while running in polynomial time.

Kim, Daniel; Kawachi, Ichiro

2006-05-01

This article highlights characteristics of two related yet distinct economic approaches to addressing the current obesity epidemic in the United States: the general taxation of soft drinks, snack foods, and/or fast foods, and the application of pricing incentives/disincentives on foods sold in schools and worksites. The article specifically focuses on the: (1) rationale for, (2) potential barriers and limitations to, and (3) possible unintended consequences of implementing these policy interventions at the state level. Novel empirical evidence showing strong positive associations between the presence of state-level taxation on soft drinks or snack foods between 1991 and 1998 and relative changes in obesity prevalence over the same time period is further presented. The article concludes by summarizing the similarities and dissimilarities of the two approaches, and by emphasizing some of the gaps and priorities regarding these strategies that should be addressed in future research and policies to best effect obesity prevention.

A Perspective on Consumers 3.0: They Are Not Better Decision-Makers than Previous Generations

2016-01-01

This perspective article builds upon the theory of local thinking in interpretation and prediction of consumer behavior in a contemporary world of information overload. It is shown that even informed and socially and environmentally responsible consumers (consumers 3.0) exhibit selective recall, limited attention, and bounded search in the perception and interpretation of price and quality of purchases. Their decisions fall into local cognitive frames, which specifically focus attention only on a narrow structure and content of the choice. The cognitive frames can be established by recent or regular purchases, but also extreme or primary purchase experiences. The article includes a short conceptual review of car, food, clothing, insurance, drugs, paintings, and other product purchases showing that the local cognitive frames often lead to bad bargains across various sectors. The article presents several suggestions for future research. PMID:27375527

Mental disorders cause impact in the work environment. Investigations of interaction among stakeholders who are involved in the return to work are scarce. Meta-ethnography serves to synthesize qualitative studies by means of ongoing interpretation and comparison of the ideas presented in the articles. The goal of this study is to present a meta-ethnography of the interactions among the stakeholders involved in the return to work process after leave of absence due to mental disorders. It aims: (1) to investigate the interactions among stakeholders involved in return to work; (2) to identify enablers or obstacles for the return to work. The database search found 619 articles, 16 of which met the inclusion criteria. Analysis of the articles revealed six second-order concepts that resulted in two syntheses. The first is about performance ethos in the return to work, and the second shows return to work as a catalyst of new life styles. Models that favor the worker's performance ethos, as well as a perspective oriented by psychosocial aspects may enable return to work practices after leave of absence due to mental disorders.

In this data article, we present a comprehensive dataset on electrical energy consumption in a university that is practically driven by Information and Communication Technologies (ICTs). The total amount of electricity consumed at Covenant University, Ota, Nigeria was measured, monitored, and recorded on daily basis for a period of 12 consecutive months (January-December, 2016). Energy readings were observed from the digital energy meter (EDMI Mk10E) located at the distribution substation that supplies electricity to the university community. The complete energy data are clearly presented in tables and graphs for relevant utility and potential reuse. Also, descriptive first-order statistical analyses of the energy data are provided in this data article. For each month, the histogram distribution and time series plot of the monthly energy consumption data are analyzed to show insightful trends of energy consumption in the university. Furthermore, data on the significant differences in the means of daily energy consumption are made available as obtained from one-way Analysis of Variance (ANOVA) and multiple comparison post-hoc tests. The information provided in this data article will foster research development in the areas of energy efficiency, planning, policy formulation, and management towards the realization of smart campuses.

Mapping cancer, cardiovascular and malaria research in Brazil.

PubMed

Rodrigues, P S; Fonseca, L; Chaimovich, H

2000-08-01

This paper presents performance indicators for the Brazilian cancer, cardiovascular and malaria research areas from 1981 to 1995. The data show an increasing number of papers since 1981 and author numbers indicate a continuous growth of the scientific community and suggest an expected impact of scientific activity on biomedical education. The data also characterize cardiovascular research as a well-established area and cancer research as a faster growing consolidating field. The 1989-1994 share of Brazilian articles among world publications shows a growing trend for the cancer (1.61) and cardiovascular (1.59) areas, and a decrease for the malaria area (0. 89). The burden of the three diseases on society is contrasted by the small number of consolidated Brazilian research groups, and a questionable balance of thematic activity, especially with regard to malaria. Brazilian periodicals play an important role in increasing the international visibility of science produced in the country. Cancer and cardiovascular research is strongly concentrated in the Southeastern and in Southern regions of Brazil, especially in São Paulo (at least one address from São Paulo in 64.5% of the 962 cancer articles and in 66.9% of the 2250 cardiovascular articles, the second state being Rio de Janeiro with at least one address in 14.1 and 11% of those articles, respectively). Malaria research (468 articles) is more evenly distributed across the country, following the pattern of the endemic distribution of the disease. Surveying these national indicator trends can be useful to establish policies in the decision process about health sciences, medical education and public health.

2014-10-01

The goal of this work is to present an analysis of articles published by the Latin American Journal of Astronomy Education (RELEA) since its beginning (2004) to the present. We analyzed the 59 articles available on the website of the journal (http://www.relea.ufscar.br), published in 15 issues. The articles were classified by: year of publication, issue, author's institutions, grade level, focus of the study and content. The results show that the number of articles is still small - although the journal has been initially qualified as B3 within the Journal Ranking scheme Qualis CAPES and in the latest ranking (current) advanced to the concept B1 in the Qualis, it is too early to expect an increase in the number of articles submitted. Among the main factors for the relatively low number of articles we can mention that the initially nominated Editorial Board did not succeed in a proper dissemination of the journal and call for papers, the ongoing absence of a ``critical mass'' of astronomy education researchers and the lack of publishing tradition in the area. Important aspects of the writing of articles submitted are also discussed, such as refereeing, acceptance rate of articles, participation of authors from countries other than Brazil and theoretical and methodological frameworks, as well as the recent editorial restructuration of the international Editorial Board of the RELEA and the nomination of Associate Editors from Brazil. Concluding, it is possible to note the contribution to the field up to the moment through citations in other works in the field. However, it is necessary to advance with regard to: publishing more articles, articles from greater variety of Latin American countries, training of the community for a minimum quality of the writing of articles submitted for publication in a journal aimed at education research. In this sense, additional analyses of the published papers would be desirable. Finally, it is pointed out the need for greater dissemination of the journal to increase the number of submissions, encouraging the diversification of contents and methods and increase the participation of authors in general and from Latin America in particular, aiming to greater academic contribution for astronomy education at various levels and places.

The quality of the abstracts presented at a conference reflects the scientific work and level of activity of the scientific association concerned. The aim of the present study was to determine the rate of publications of podium presentations and posters at the conferences of the European Paediatric Orthopaedic Society (EPOS) from 2006 to 2008 and to identify factors that favor publication in peer-reviewed journals. The results are compared with those of other international societies. All 646 abstracts (including podiums, posters, and e-posters) presented at the EPOS conferences were investigated using the PubMed database to identify any corresponding published articles in the journals listed in the database. A period of 5 years before and after the relevant conference was used for the PubMed search. Factors influencing publication and the quality of the study, such as the type of presentation and the level of evidence, were also investigated. A publication rate of 36.7% was observed, corresponding to 237 publications of 646 abstracts. The period to publication showed a mean of 13.88 ± 1.34 months. It was found that abstracts of podium presentations were published significantly more often than poster abstracts (P<0.001). Experimental studies, with a publication rate of 50.9%, showed better results than clinical studies (36.0%). Overall, the articles were published in 61 different journals, with the largest number (n=50) appearing in the Journal of Pediatric Orthopaedics. In addition, the present study shows that abstracts with a higher level of evidence were associated with a higher publication rate. At 36.7%, the rate of publication of EPOS abstracts is within the range reached by other specialist orthopaedics societies, such as the German Society of Orthopaedics and Trauma Surgery (36%) and the British Orthopaedic Association (36%). However, it is lower than the publication rate of the Pediatric Orthopaedic Society of North America (POSNA), at 50%. The high percentage of unpublished conference abstracts (63%), which did not go through a peer-reviewed process, casts doubts upon the practice of utilizing the citation of abstracts based purely on conference abstracts.

Since its inception in 2005, articles in Health Promotion Practice's social marketing department have focused on describing social marketing's unique contributions and the application of each to the practice of health promotion. This article provides a brief review of six unique features (marketing mix, consumer orientation, segmentation, exchange, competition, and continuous monitoring) and then presents two case studies-one on reducing stigma related to mental health and the other a large-scale campaign focused on increasing HIV testing among African American youth. The two successful case studies show that social marketing principles can be applied to a wide variety of topics among various population groups.

From affliction to affirmation: narrative transformation and the therapeutics of Candomblé mediumship.

Seligman, Rebecca

2005-06-01

Through the presentation and analysis of a prototypical mediumship narrative, this article shows how individuals initiated into the Candomblé religion of north-eastern Brazil come to alter their own self-narratives by learning and internalizing the cultural model for an established social/religious role: that of the medium. As individuals come to identify with this 'role model,' they are able to reinterpret their own life histories in terms of the model's structure and its symbolic content. This article also demonstrates how the social articulation and cognitive internalization of this new self-narrative act therapeutically, to foster a positive transformation in self-understanding that facilitates positive behavior.

The diffusion of recent regulations on work safety has captured mass-media's interest on work accidents. The present work aims to highlight the role of print media in building a social representation of work safety, by performing a qualitative analysis of articles published between 2009 and 2010 in three of the main national newspapers. Results showed that print media are accurate in reporting news, but they do not serve as source of education in work safety's issues. Information is mainly focused around catastrophic events, with headlines inducing negative emotions. Very few articles contain a critical discussion of methods and operational proposals tested around the Country. A possible transformation of media's role in promoting work safety is discussed.

2018-05-01

Between 1962 and 2004, Nobel Prize laureates appear in the British television science programme Horizon in various roles, denoting differing understandings of science in relation to society and culture. These representations are the outcome of an interplay of cultural and institutional factors. They vary with the broadcasting environment. Notably, the article establishes that the choice of presenting scientists as heroic characters in strongly determined storylines from the late-1990s onwards originates in a reaction to institutional imperatives as a means to preserve the existence of the Horizon series. The article shows that exigencies of the institutional context in which media professionals operate are major factors influencing the representation of science in public.

The hyperlinks pointing from one Wikipedia article to another are treated as directed links while the articles represent the nodes of the network. We show that many network characteristics are common to different language versions of Wikipedia, such as their degree distributions, growth, topology, reciprocity, clustering, assortativity, path lengths, and triad significance profiles. These regularities, found in the ensemble of Wikipedias in different languages and of different sizes, point to the existence of a unique growth process. We also compare Wikipedias to other previously studied networks.

The present article describes the case of two men, 18 and 30 years respectively, in whom renal insufficiency was discovered incidently. In the two cases renography showed 46 and 30% of expected function given two healthy kidneys. They had neither experienced clinical symptoms of urinary tract disorder, been operated upon, nor endoscopically examined. Micturition was normal without any sign of vesicourethral dysfunction. Micturition cystography revealed severe vesicoureteral reflux in both patients. They were treated by bilateral ureterovesical reimplantation. The cases presented here show that primary vesicoureteral reflux complicated by impaired renal function can be revealed in adults who have had no symptoms of urinary tract disorder. In these cases the probable cause of renal damage is the mechanical effect of reflux ("water-hammer effect") alone.

An entropy-based analysis of lane changing behavior: An interactive approach.

PubMed

Kosun, Caglar; Ozdemir, Serhan

2017-05-19

As a novelty, this article proposes the nonadditive entropy framework for the description of driver behaviors during lane changing. The authors also state that this entropy framework governs the lane changing behavior in traffic flow in accordance with the long-range vehicular interactions and traffic safety. The nonadditive entropy framework is the new generalized theory of thermostatistical mechanics. Vehicular interactions during lane changing are considered within this framework. The interactive approach for the lane changing behavior of the drivers is presented in the traffic flow scenarios presented in the article. According to the traffic flow scenarios, 4 categories of traffic flow and driver behaviors are obtained. Through the scenarios, comparative analyses of nonadditive and additive entropy domains are also provided. Two quadrants of the categories belong to the nonadditive entropy; the rest are involved in the additive entropy domain. Driving behaviors are extracted and the scenarios depict that nonadditivity matches safe driving well, whereas additivity corresponds to unsafe driving. Furthermore, the cooperative traffic system is considered in nonadditivity where the long-range interactions are present. However, the uncooperative traffic system falls into the additivity domain. The analyses also state that there would be possible traffic flow transitions among the quadrants. This article shows that lane changing behavior could be generalized as nonadditive, with additivity as a special case, based on the given traffic conditions. The nearest and close neighbor models are well within the conventional additive entropy framework. In this article, both the long-range vehicular interactions and safe driving behavior in traffic are handled in the nonadditive entropy domain. It is also inferred that the Tsallis entropy region would correspond to mandatory lane changing behavior, whereas additive and either the extensive or nonextensive entropy region would match discretionary lane changing behavior. This article states that driver behaviors would be in the nonadditive entropy domain to provide a safe traffic stream and hence with vehicle accident prevention in mind.

Articles regarding cosmetic surgery were coded from the top five most circulated English-language women's magazines in Canada between 2002 and 2006 for type of procedure, patient demographics, risk information, and indicators of emotional health. Content analysis techniques were used to identify patterns of portraying the risks and benefits of cosmetic surgery. Content analyses show the articles tend to present readers with detailed physical health risk information. However, 48% of articles discuss the impact that cosmetic surgery has on emotional health, most often linking cosmetic surgery with enhanced emotional well-being regardless of the patient's pre-existing state of emotional health. The articles also tend to use accounts given by males to provide defining standards of female attractiveness. These findings are consistent with arguments in the research literature that women's magazines contribute to the medicalization of the female body. Cosmetic surgery is generally portrayed as a risky--but worthwhile--option for women to enhance both their physical appearance and emotional health. The implications for future research and public education strategies are discussed.

Our journey to digital curation of the Jeghers Medical Index

PubMed Central

Gawdyda, Lori; Carter, Kimbroe; Willson, Mark; Bedford, Denise

2017-01-01

Background Harold Jeghers, a well-known medical educator of the twentieth century, maintained a print collection of about one million medical articles from the late 1800s to the 1990s. This case study discusses how a print collection of these articles was transformed to a digital database. Case Presentation Staff in the Jeghers Medical Index, St. Elizabeth Youngstown Hospital, converted paper articles to Adobe portable document format (PDF)/A-1a files. Optical character recognition was used to obtain searchable text. The data were then incorporated into a specialized database. Lastly, articles were matched to PubMed bibliographic metadata through automation and human review. An online database of the collection was ultimately created. The collection was made part of a discovery search service, and semantic technologies have been explored as a method of creating access points. Conclusions This case study shows how a small medical library made medical writings of the nineteenth and twentieth centuries available in electronic format for historic or semantic research, highlighting the efficiencies of contemporary information technology.

The workings of homonormativity: lesbian, gay, bisexual, and queer discourses on discrimination and public displays of affections in Portugal.

PubMed

de Oliveira, João Manuel; Costa, Carlos Gonçalves; Nogueira, Conceição

2013-01-01

This article analyzes how heteronormative discourse may be (re)produced by the very same people it serves to oppress, binding heteronormativity to a specific form of homonormativity. Furthermore, this article also links Portuguese history and society by discussing the context and the recent legal changes that led to legislation providing for same-sex marriage. Using thematic analysis of 14 interviews, this article demonstrates how heteronorms are upheld in the discourses of the lesbian, gay, bisexual, and queer (LGBQ) participants. Themes linked to public displays of affection and discrimination emerged from the interviews. Participant discourses are analyzed in terms of their incorporation of heteronorms. Homonormativity is present in both the themes subject to analysis. Analysis of the interviews shows how transgressing the heteronorm implies costs and is ultimately perceived as a personal risk. This article concludes that the lack of discursive resistance denies the possibility of re-signification and subversion even in LGBQ discourses. This clearly indicates the pervasiveness of discourses reiterating heteronorms, even those issued by those most oppressed by such norms.

The risk of congenital malformations appears to be higher in infants of mothers with mental disorders as compared to those of mothers with no history of psychiatric illness. This article presents a meta-analysis of studies on the association between maternal mental illness and congenital malformations. The review consisted of an article search in the MEDLINE, ISIWEB, Scopus, and SciELO databases, using the following key words: "mental disorders" OR "mental health" OR "psychotic disorders" OR "schizophrenia" AND "congenital abnormalities" OR "birth defects". A total of 108 studies were identified, and five articles were selected according to the established criteria. These articles were included in a meta-analysis, involving a total of 4,194 children of mothers with mental illness and 249,548 children of mothers with no such disorders. Pooled relative risk showed a significant association between exposure to mental illness in mothers and risk of malformations in newborns (RR = 2.06, 95%CI: 1.46-2.67). The study highlights the relationship between maternal mental health during pregnancy and its effects on the infant's health.

2018-01-01

Provisional restorations represent an important phase during the rehabilitation process, knowledge of the mechanical properties of the available materials allows us to predict their clinical performance. At present, there is no systematic review, which supports the clinicians’ criteria, in the selection of a specific material over another for a particular clinical situation. The purpose of this systematic review and meta-analysis was to assess and compare the mechanical properties of dimethacrylates and monomethacrylates used in fabricating direct provisional restorations, in terms of flexural strength, fracture toughness and hardness. This review followed the PRISMA guidelines. The searches were conducted in PubMed, Embase, Web of Science, Scopus, the New York Academy of Medicine Grey Literature Report and were complemented by hand-searching, with no limitation of time or language up to January 10, 2017. Studies that assess and compare the mechanical properties of dimethacrylate- and monomethacrylate-based provisional restoration materials were selected. A quality assessment of full-text articles were performed according to modified ARRIVE and CONSORT criteria and modified Cochrane Collaboration’s tool for in vitro studies. Initially, 256 articles were identified. After removing the duplicates and applying the selection criteria, 24 articles were included in the qualitative synthesis and 7 were included in the quantitative synthesis (meta-analysis). It may be concluded that dimethacrylate-based provisional restorations presented better mechanical behavior than monomethacrylate-based ones in terms of flexural strength and hardness. Fracture toughness showed no significant differences. Within the monomethacrylate group, polymethylmethacrylate showed greater flexural strength than polyethylmethacrylate. PMID:29489883

To examine how health advice is provided in popular magazines and the quality of that advice. A prospective quantitative analysis of the quality of health advice provided in Australian magazines between July and December 2011 was conducted. A rating instrument was adapted from the Media Doctor Australia rating tool used to assess quality of health news reporting. Criteria included: recommends seeing a doctor; advice based on reliable evidence; advice clear and easily applied; benefits presented meaningfully; potential harms mentioned; evidence of disease mongering; availability and cost of treatments; obvious advertising; vested interest, and anecdotal evidence. 163 health advice articles were rated showing a wide variation in the quality of advice presented between magazines. Magazines with 'health' in the title, rated most poorly with only 36% (26/73) of these articles presenting clear and meaningful advice and 52% (38/73) giving advice based on reliable evidence. Australian magazines, especially those with health in the title, generally presented poor quality, unreliable health advice. Teen magazine Dolly provided the highest quality advice. Consumers need to be aware of this when making health choices. © 2016 Public Health Association of Australia.

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.

Improved control of the betatron coupling in the Large Hadron Collider

NASA Astrophysics Data System (ADS)

Persson, T.; Tomás, R.

2014-05-01

The control of the betatron coupling is of importance for safe beam operation in the LHC. In this article we show recent advancements in methods and algorithms to measure and correct coupling. The benefit of using a more precise formula relating the resonance driving term f1001 to the ΔQmin is presented. The quality of the coupling measurements is increased, with about a factor 3, by selecting beam position monitor (BPM) pairs with phase advances close to π/2 and through data cleaning using singular value decomposition with an optimal number of singular values. These improvements are beneficial for the implemented automatic coupling correction, which is based on injection oscillations, presented in the article. Furthermore, a proposed coupling feedback for the LHC is presented. The system will rely on the measurements from BPMs equipped with a new type of high resolution electronics, diode orbit and oscillation, which will be operational when the LHC restarts in 2015. The feedback will combine the coupling measurements from the available BPMs in order to calculate the best correction.

History brings together meanings related to earlier periods, being aware of the past as a panorama to reread the present. Madeleine Leininger presented in 1970 an implicit and respectful message to the Nursing Profession when introducing Nursing and Anthropology. Two Worlds to Blend. Implicitly: Nursing you disregard culture. This article shows the absence of the history of anthropology and of nursing within Transcultural Nursing and it includes how education has influenced theoretic, methodological, and comparative approaches giving researchers the responsibility to decide their fundamentals. Berthoud (2001) has inspired the anthropological and historic perspectives of the author, thus universalism, relativism, and comparison are presented.

Hyperkalaemia in the age of aldosterone antagonism.

PubMed

Chapagain, A; Ashman, N

2012-11-01

Hyperkalaemia is well recognized as a medical emergency. However, with the publication of trials showing benefit with renin-aldosterone axis suppression in heart failure, the epidemiology of patients presenting with hyperkalaemia has changed. The reported incidence of rate of serious hyperkalaemia (>6.0 mEq/l of potassium) ranges from 6 to 12% in patients on spironolactone with congestive cardiac failure (CCF). A rational choice of therapy based on present evidence is different from the traditionally used algorithm, given our understanding of the physiology relevant to this patient group. This article discusses the changing face of hyperkalaemia and the present evidence and discusses options in treatment of hyperkalaemia.

Simultaneous effects of photo- and radio- darkening in ytterbium-doped aluminosilicate fibers

We present original characterizations of photo-radio-darkening in ytterbium-doped silica optical fibers submitted to the simultaneous action of the pump and of an ionizing radiation. We present the interplay between both radiations, showing e.g. that the pump is able to darken or bleach the fiber depending on the ionizing dose. The photo-resistance of the fiber is shown to play a crucial role on its radio-resistance, and that photo-resistant fibers should be also radio-resistant in low dose rate conditions. All the results are thoroughly explained by a physical model presented in a separate article by Mady et al. (this conference proceeding)

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.

Publication bias in dermatology systematic reviews and meta-analyses.

PubMed

Atakpo, Paul; Vassar, Matt

2016-05-01

Systematic reviews and meta-analyses in dermatology provide high-level evidence for clinicians and policy makers that influence clinical decision making and treatment guidelines. One methodological problem with systematic reviews is the under representation of unpublished studies. This problem is due in part to publication bias. Omission of statistically non-significant data from meta-analyses may result in overestimation of treatment effect sizes which may lead to clinical consequences. Our goal was to assess whether systematic reviewers in dermatology evaluate and report publication bias. Further, we wanted to conduct our own evaluation of publication bias on meta-analyses that failed to do so. Our study considered systematic reviews and meta-analyses from ten dermatology journals from 2006 to 2016. A PubMed search was conducted, and all full-text articles that met our inclusion criteria were retrieved and coded by the primary author. 293 articles were included in our analysis. Additionally, we formally evaluated publication bias in meta-analyses that failed to do so using trim and fill and cumulative meta-analysis by precision methods. Publication bias was mentioned in 107 articles (36.5%) and was formally evaluated in 64 articles (21.8%). Visual inspection of a funnel plot was the most common method of evaluating publication bias. Publication bias was present in 45 articles (15.3%), not present in 57 articles (19.5%) and not determined in 191 articles (65.2%). Using the trim and fill method, 7 meta-analyses (33.33%) showed evidence of publication bias. Although the trim and fill method only found evidence of publication bias in 7 meta-analyses, the cumulative meta-analysis by precision method found evidence of publication bias in 15 meta-analyses (71.4%). Many of the reviews in our study did not mention or evaluate publication bias. Further, of the 42 articles that stated following PRISMA reporting guidelines, 19 (45.2%) evaluated for publication bias. In comparison to other studies, we found that systematic reviews in dermatology were less likely to evaluate for publication bias. Evaluating and reporting the likelihood of publication bias should be standard practice in systematic reviews when appropriate. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Review of journal of cardiovascular magnetic resonance 2010

PubMed Central

2011-01-01

There were 75 articles published in the Journal of Cardiovascular Magnetic Resonance (JCMR) in 2010, which is a 34% increase in the number of articles since 2009. The quality of the submissions continues to increase, and the editors were delighted with the recent announcement of the JCMR Impact Factor of 4.33 which showed a 90% increase since last year. Our acceptance rate is approximately 30%, but has been falling as the number of articles being submitted has been increasing. In accordance with Open-Access publishing, the JCMR articles go on-line as they are accepted with no collating of the articles into sections or special thematic issues. Last year for the first time, the Editors summarized the papers for the readership into broad areas of interest or theme, which we felt would be useful to practitioners of cardiovascular magnetic resonance (CMR) so that you could review areas of interest from the previous year in a single article in relation to each other and other recent JCMR articles [1]. This experiment proved very popular with a very high rate of downloading, and therefore we intend to continue this review annually. The papers are presented in themes and comparison is drawn with previously published JCMR papers to identify the continuity of thought and publication in the journal. We hope that you find the open-access system increases wider reading and citation of your papers, and that you will continue to send your quality manuscripts to JCMR for publication. PMID:21914185

Two-Stage Surgical Management of Multilevel Symptomatic Thoracic Haemangioma Using Ethanol and Iliac Crest Bone Graft

PubMed Central

2014-01-01

This article presents a 56-year-old obese female who presented with back pain and progressive weakness in her lower limbs for three months. She was bed-ridden for one week before reporting to our hospital. Plain radiographs showed vertical striations in multiple vertebrae classical of haemangioma. Magnetic resonance imaging (MRI) spine revealed multiple thoracic and lumbar vertebral haemangiomas. Extra osseous extension of haemangioma at T12 was causing spinal cord compression. Two-stage surgery was performed with absolute alcohol (ethanol) injection followed by pedicle screw fixation and decompression with tricortical iliac crest bone graft into the vertebral body. Postoperatively rapid neurological improvement was seen. After three weeks, she could walk independently. One year later, computed tomography showed complete incorporation of bone graft and maintained vertebral body height. MRI showed complete resolution of the cord edema at T12. These findings indicated diminished vascularity of the tumor. PMID:25187869

We describe a 52-year-old woman presenting with acute onset of severe burning paraesthesia in the hands and feet associated with allodynia and antalgic gait. At the time of admission to hospital no motor weakness was present. A diagnosis of Guillain-Barré syndrome (GBS) was considered when neurophysiological studies were completed showing convincing evidence of demyelination on motor conduction studies and sural sparing on sensory nerve studies. 1 We describe this case as a sensory variant of GBS. Clinical improvement followed treatment with a single course of intravenous immunoglobulin (IVIG). The patient made a complete clinical recovery within 6 months of onset and repeat neurophysiological studies showed marked improvement. We encourage clinicians to consider an atypical variant of GBS in patients presenting with acute sensory complaints. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Clinical evidence vs preliminary speculation in newspaper coverage of diabetes innovations: a quantitative analysis.

PubMed

Vehof, H; Sanders, J; van Dooren, A; Heerdink, E; Das, E

2018-05-04

Researchers have discussed that journalistic reporting of medical developments is often characterised by exaggeration or lack of context, but additional quantitative evidence to support this claim is needed. This study introduces a quantitative approach to assessing coverage of medical innovations, by aiming at provided references to observed clinical effects. Although observed clinical effects reflect increased chances for future medical applications, it is unknown to which extent newspaper articles refer to it when spreading health information. We aimed to assess, over a 6-year period, newspaper publication characteristics of diabetes innovations, arising from all scientific areas of interest, regarding the total count and the proportion of articles that provide references to demonstrated clinical efficacy. Quantitative content analysis of newspaper articles covering innovative treatments for diabetes. We performed a systematic review of newspaper articles between 2011 and 2016 printed in the largest six Dutch newspapers. By assessing in-article references, it was possible to quickly distinguish between (1) articles that referred to actual clinical efficacy demonstrated in a scientific setting and (2) articles that presented either predictions, fundamental research, preclinical research or personal experiences and recommendations. Proportion differences between scientific areas of interest were analysed using the chi-squared test. A total of 613 articles were categorised. Total newspaper publication frequency increased with 9.9 articles per year (P = .031). In total, 17% of the articles contained a reference to any proven clinical efficacy. Articles about human nutrition science (7%; P = .001) and (neuro)psychology (4.3%; P = .014) less frequently provided a reference to actual clinical efficacy. Our findings show that less than one in five newspaper articles about diabetes research contains a reference to relevant clinical effects, while the publication count is increasing. These statistics may contribute to feelings of false hope and confusion in patients. Copyright © 2018 The Royal Society for Public Health. Published by Elsevier Ltd. All rights reserved.

Challenges and Developments in the Assessment of (Mal)adaptive Personality and Pathological States in Older Adults.

PubMed

Rossi, Gina; Videler, Arjan; van Alphen, S P J

2018-04-01

Since older adults often show an atypical presentation of (mal)adaptive personality traits and pathological states, the articles in this special issue will concisely discuss some perennial issues in clinical assessment in older adults and thus outline the main challenges this domain faces. By bringing empirical work and meta-analytic studies from leading scholars in the field of geropsychology, the articles will also address these challenges by reporting the latest developments in the field. This way, we hope to reshape the way clinicians and researchers assess (mal)adaptive personality and pathological states in older adults into a more reliable and valid assessment method that integrates the specific biopsychosocial context of older age.

NASA Technical Reports Server (NTRS)

Masters, W. C.; Scheeres, D. J.; Thurman, S. W.

1994-01-01

The theoretical aspects of an orbit determination filter that incorporates ground-system error sources as model parameters for use in interplanetary navigation are presented in this article. This filter, which is derived from sequential filtering theory, allows a systematic treatment of errors in calibrations of transmission media, station locations, and earth orientation models associated with ground-based radio metric data, in addition to the modeling of the spacecraft dynamics. The discussion includes a mathematical description of the filter and an analytical comparison of its characteristics with more traditional filtering techniques used in this application. The analysis in this article shows that this filter has the potential to generate navigation products of substantially greater accuracy than more traditional filtering procedures.

Shishkin, E. V.; Kazakov, S. V.

2017-10-01

This article describes the results of theoretical and experimental studies of a vibratory-percussion crusher, which is driven from a pair of self-synchronizing vibration exciters, attached to the shell symmetrically about its vertical axis. In addition to that, crusher’s dynamic model is symmetrical and balanced. Forced oscillation laws for crusher working members and their amplitude-frequency characteristics have been inducted. Domains of existence of synchronous opposite-phase oscillations of crusher working members (crusher’s operating mode) and crusher capabilities have been identified. The results of mechanical and technological tests of a pilot crusher presented in the article show that this crusher may be viewed as an advanced machine for disintegration of supertough materials with minimum regrinding of finished products.

Pros and cons of healthcare information technology implementation: the pros win.

PubMed

Maffei, Roxana

2006-01-01

Countless studies and investigations have been performed siding either for or against the implementation of technology in the healthcare setting. This article presents both sides of this debate, with an obvious conclusion that the pros of this debate win. The practice of information technology in the medical domain lags behind its knowledge and discovery by at least 7 years. The key to closing this gap is to show, through various studies, how information technology systems provide decision support to users at the point in time when decisions are needed. What the reader will obtain from this article is that the pros for information technology implementation in healthcare settings weigh much more and have a greater effect than the cons.

Retropharyngeal course of the internal carotid artery.

Ballivet de Regloix, Stanislas; Maurin, O

2017-12-01

A 77-year-old male patient presented with dysphonia. Endoscopic examination demonstrated a distortion of the posterior pharyngeal wall, which was pulsatile. The axial CT showed left internal carotid artery in a retropharyngeal location. An anomalous course of the carotid artery in the retropharyngeal space is an unusual finding that poses a risk of vascular injury during pharyngeal surgery and intubation. Such an anomaly may be congenital (incomplete descent of the third aortic arch) and may be more pronounced in older patients secondary to atherosclerosis and hypertension as occurred in our case noted here. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

2016-01-01

This article reports the case of a 68-year-old patient with anti-HU antibodies paraneoplastic encephalitis. The clinical manifestations were atypical and the paraclinical work-up, notably the magnetic resonance imaging (MRI) showing bilateral posterior thalamic hyperintensities (pulvinar sign), misleadingly pointed towards a variant Creutzfeld–Jakob disease. After presenting the case, the differential diagnosis of the pulvinar sign is discussed along with other important diagnostic considerations. PMID:27558994

2015-01-01

Biomedical Informatics is a growing interdisciplinary field in which research topics and citation trends have been evolving rapidly in recent years. To analyze these data in a fast, reproducible manner, automation of certain processes is needed. JAMIA is a “generalist” journal for biomedical informatics. Its articles reflect the wide range of topics in informatics. In this study, we retrieved Medical Subject Headings (MeSH) terms and citations of JAMIA articles published between 2009 and 2014. We use tensors (i.e., multidimensional arrays) to represent the interaction among topics, time and citations, and applied tensor decomposition to automate the analysis. The trends represented by tensors were then carefully interpreted and the results were compared with previous findings based on manual topic analysis. A list of most cited JAMIA articles, their topics, and publication trends over recent years is presented. The analyses confirmed previous studies and showed that, from 2012 to 2014, the number of articles related to MeSH terms Methods, Organization & Administration, and Algorithms increased significantly both in number of publications and citations. Citation trends varied widely by topic, with Natural Language Processing having a large number of citations in particular years, and Medical Record Systems, Computerized remaining a very popular topic in all years.

Horizontal lifelines - review of regulations and simple design method considering anchorage rigidity.

PubMed

Galy, Bertrand; Lan, André

2018-03-01

Among the many occupational risks construction workers encounter every day falling from a height is the most dangerous. The objective of this article is to propose a simple analytical design method for horizontal lifelines (HLLs) that considers anchorage flexibility. The article presents a short review of the standards and regulations/acts/codes concerning HLLs in Canada the USA and Europe. A static analytical approach is proposed considering anchorage flexibility. The analytical results are compared with a series of 42 dynamic fall tests and a SAP2000 numerical model. The experimental results show that the analytical method is a little conservative and overestimates the line tension in most cases with a maximum of 17%. The static SAP2000 results show a maximum 2.1% difference with the analytical method. The analytical method is accurate enough to safely design HLLs and quick design abaci are provided to allow the engineer to make quick on-site verification if needed.

Fuzzy logic for plant-wide control of biological wastewater treatment process including greenhouse gas emissions.

PubMed

Santín, I; Barbu, M; Pedret, C; Vilanova, R

2018-06-01

The application of control strategies is increasingly used in wastewater treatment plants with the aim of improving effluent quality and reducing operating costs. Due to concerns about the progressive growth of greenhouse gas emissions (GHG), these are also currently being evaluated in wastewater treatment plants. The present article proposes a fuzzy controller for plant-wide control of the biological wastewater treatment process. Its design is based on 14 inputs and 6 outputs in order to reduce GHG emissions, nutrient concentration in the effluent and operational costs. The article explains and shows the effect of each one of the inputs and outputs of the fuzzy controller, as well as the relationship between them. Benchmark Simulation Model no 2 Gas is used for testing the proposed control strategy. The results of simulation results show that the fuzzy controller is able to reduce GHG emissions while improving, at the same time, the common criteria of effluent quality and operational costs.

Equipment and Energy Usage in a Large Teaching Hospital in Norway.

PubMed

Rohde, Tarald; Martinez, Robert

2015-01-01

This article presents a study of how equipment is used in a Norwegian University hospital and suggests ways to reduce hospital energy consumption. Analysis of energy data from Norway's newest teaching hospital showed that electricity consumption was up to 50% of the whole-building energy consumption. Much of this is due to the increasing energy intensity of hospital-specific equipment. Measured power and reported usage patterns for equipment in the studied departments show daytime energy intensity of equipment at about 28.5 kBTU/ft2 per year (90 kWh/m2 per year), compared to building code standard value of only 14.9 kBTU/ft2 (47 kWh/m2 per year) for hospitals. This article intends to fill gaps in our understanding of how users and their equipment affect the energy balance in hospitals and suggests ways in which designers and equipment suppliers can help optimize energy performance while maintaining quality in the delivery of health services.

[Family violence and aggressive and oppositional behavior in childhood: a literature review].

PubMed

Pesce, Renata

2009-01-01

This article presents a review of the world literature about two important subjects: family violence and problems of aggressive behavior and oppositional defiant disorder in childhood. We opted for publications that had used the CBCL- Child Behavior Checklist for investigating behavior problems in children. This instrument is internationally recognized for its reliability and validity, considered an efficient tool for identifying behavior problems in children. Our findings showed that marital violence predominated in the studies as kind of familiar violence able to cause problems of aggressiveness and transgression in children. Another point discussed was the lack of consensus on the terms used in the articles to refer to such behavior problems. The review showed the need for in-depth studies into this subject, mainly in the sense of thinking about prevention and health promotion in childhood and adolescence. Aggressive behavior in children tends to remain and increase over time, a fact that points to the need for strategies for preventing these problems in the school, familiar and health environments.

[Potentials in the regionalization of health indicators using small-area estimation methods : Exemplary results based on the 2009, 2010 and 2012 GEDA studies].

Nationwide health surveys can be used to estimate regional differences in health. Using traditional estimation techniques, the spatial depth for these estimates is limited due to the constrained sample size. So far - without special refreshment samples - results have only been available for larger populated federal states of Germany. An alternative is regression-based small-area estimation techniques. These models can generate smaller-scale data, but are also subject to greater statistical uncertainties because of the model assumptions. In the present article, exemplary regionalized results based on the studies "Gesundheit in Deutschland aktuell" (GEDA studies) 2009, 2010 and 2012, are compared to the self-rated health status of the respondents. The aim of the article is to analyze the range of regional estimates in order to assess the usefulness of the techniques for health reporting more adequately. The results show that the estimated prevalence is relatively stable when using different samples. Important determinants of the variation of the estimates are the achieved sample size on the district level and the type of the district (cities vs. rural regions). Overall, the present study shows that small-area modeling of prevalence is associated with additional uncertainties compared to conventional estimates, which should be taken into account when interpreting the corresponding findings.

Carbonate Minerals with Magnesium in Triassic Terebratula Limestone in the Term of Limestone with Magnesium Application as a Sorbent in Desulfurization of Flue Gases

Stanienda-Pilecki, Katarzyna

2017-09-01

This article presents the results of studies of Triassic (Muschelkalk) carbonate rock samples of the Terebratula Beds taken from the area of the Polish part of the Germanic Basin. It is the area of Opole Silesia. The rocks were studied in the term of possibility of limestone with magnesium application in desulfurization of flue gases executed in power plants. Characteristic features of especially carbonate phases including magnesium-low-Mg calcite, high-Mg calcite, dolomite and huntite were presented in the article. They were studied to show that the presence of carbonate phases with magnesium, especially high-Mg calcite makes the desulfurization process more effective. Selected rock samples were examined using a microscope with polarized, transmitted light, X-ray diffraction, microprobe measurements and FTIR spectroscopy. The results of studies show a domination of low magnesium calcite in the limestones of the Terebratula Beds. In some samples dolomite and lower amounts of high-Mg calcite occurred. Moreover, huntite was identified. The studies were very important, because carbonate phases like high-Mg calcite and huntite which occurred in rocks of the Triassic Terebratula Beds were not investigated in details by other scientists but they presence in limestone sorbent could influence the effectiveness of desulfurization process.

Auditory Scene Analysis: An Attention Perspective

PubMed Central

2017-01-01

Purpose This review article provides a new perspective on the role of attention in auditory scene analysis. Method A framework for understanding how attention interacts with stimulus-driven processes to facilitate task goals is presented. Previously reported data obtained through behavioral and electrophysiological measures in adults with normal hearing are summarized to demonstrate attention effects on auditory perception—from passive processes that organize unattended input to attention effects that act at different levels of the system. Data will show that attention can sharpen stream organization toward behavioral goals, identify auditory events obscured by noise, and limit passive processing capacity. Conclusions A model of attention is provided that illustrates how the auditory system performs multilevel analyses that involve interactions between stimulus-driven input and top-down processes. Overall, these studies show that (a) stream segregation occurs automatically and sets the basis for auditory event formation; (b) attention interacts with automatic processing to facilitate task goals; and (c) information about unattended sounds is not lost when selecting one organization over another. Our results support a neural model that allows multiple sound organizations to be held in memory and accessed simultaneously through a balance of automatic and task-specific processes, allowing flexibility for navigating noisy environments with competing sound sources.

Steynberg, S; Rossouw, S F

1995-01-01

This paper describes the use of a document delivery test (DDT) to measure the availability of biomedical research journals in South African health sciences libraries. The methodology employed was developed twenty years ago by a team of researchers from the Institute for the Advancement of Medical Communication under the direction of R. H. Orr. The testing of the methodology was in itself an objective of the present research. A citation pool consisting of 307 items was constructed from references to journal articles in papers published in 1989 by South African biomedical researchers. The availability of each article was determined at each of seven medical library sites; the performance was measured and presented as an arithmetical value or document delivery capability index (CI). The results of the tests show a high level of availability, ranging from CI = 81.68 to CI = 92.97 for the journals sampled. The DDT methodology was found to be practical, applicable to such studies, and flexible. Its use is recommended for similar studies. Images PMID:7703944

The article gives an insight into the practice of Integrated Family Counseling and identifies their interfaces with psychotherapeutic approaches. The example of the child-centered educational counseling shows how consultancy, systemic and psychotherapeutic interventions interact in order to meet the parents educational needs defined by the parents. The first part of the article explains the term of Integrated Family Counseling, differentiates the various substantive areas of work and outlines the systematic attitude. The second part describes the psychotherapy-systemic action in the child-centered educational counseling from the perspective of the practice. Main priorities in the course of counseling, including cause-related behavioral and developmental diagnostics, play therapy intervention and parental involvement are presented. Here the systemic approach, major methodological elements as well as their effects are pointed up. The third part is devoted to the reflection of the relationship between counseling and psychotherapy. It becomes clear that in particular the intended effectiveness of an intervention determines their methodological design to a large extent.

Fetoscopy for meningomyelocele repair: past, present and future

PubMed Central

Bevilacqua, Nicole Silva; Pedreira, Denise Araujo Lapa

2015-01-01

ABSTRACT Meningomyelocele is a malformation with high prevalence, and one of its main comorbidities is Arnold-Chiari malformation type II. The intrauterine repair of this defect has been studied to reduce the progressive spinal cord damage during gestation. The purpose of the present review was to describe the evolution of fetal surgery for meningomyelocele repair. Searches on PubMed database were conducted including articles published in the last 10 years. Twenty-seven articles were selected, 16 experimental studies and 11 studies in humans. A recent study demonstrated that the fetal correction results in better prognosis of neurological and psychomotor development, but open surgery, which has being used widely, has considerable maternal risks. Studies in animal and human models show that the endoscopic approach is feasible and leads to lower maternal morbidity rates. Two endoscopic techniques are currently under assessment - one in Germany and another in Brazil, and we believe that the endoscopic approach will be the future technique for prenatal repair of this defect.

Juniperus phoenicea var. turbinata (Guss.) Parl. Leaf Essential Oil Variability in the Balkans.

PubMed

Rajčević, Nemanja F; Labus, Marina G; Dodoš, Tanja Z; Novaković, Jelica J; Marin, Petar D

2018-06-15

In the present work leaf essential oil from 97 individuals of Juniperus phoenicea var. turbinata (GUSS.) PARL. from the Balkan Peninsula was analysed. The essential oil was dominated by monoterpene hydrocarbons (45.5 - 71.8%), of which α-pinene was the most abundant in almost all of the samples (38.2 - 55.8%). Several other monoterpenes and sesquiterpenes were also present in relatively high abundances in samples such as myrcene, δ-3-carene, ß-phellandrene, α-terpinyl acetate, (E)-caryophyllene and germacrene D. Multivariate statistical analysis suggested the existence of three possible chemotypes based on the abundance of the four components. Even though the intrapopulation variability was high, discriminant analysis (DA) was able to separate populations. DA showed high separation between western and eastern populations but also grouped geographically closer populations along the west Balkan shoreline. The potential influence of the climate on the composition of the essential oil was also studied. This article is protected by copyright. All rights reserved. This article is protected by copyright.

A micro-level model of employment relations and health inequalities.

PubMed

Benach, Joan; Solar, Orielle; Santana, Vilma; Castedo, Antía; Chung, Haejoo; Muntaner, Carles

2010-01-01

Theoretical models are a way of visualizing, in context, the many factors that contribute to inequalities in health. This article presents a model showing the micro-level pathways relating employment and working conditions to health inequalities. A first important (indirect) pathway runs through the unequal distribution of harmful working conditions. Both employment and working conditions tend to be unequally distributed along the same social axes: social class, gender, ethnicity/race, immigration/migration status, territory, and so forth. Underlying mechanisms are exploitation, domination, and discrimination. Material deprivation and economic inequalities constitute a second direct pathway linking (nonstandard) employment conditions to health inequalities. In a third pathway, employment conditions may have an important effect on health inequalities via several psychosocial, behavioral, and physiopathological pathways. Although these several pathways are separated for analytical purposes, they are largely intertwined and, ideally, should be studied in an integrated way. The theoretical model presented in this article serves three main purposes: providing analytical clarity for organizing scientific data, encouraging further observation and causal testing, and identifying policy entry points.

The effect of physical height on workplace success and income: preliminary test of a theoretical model.

PubMed

Judge, Timothy A; Cable, Daniel M

2004-06-01

In this article, the authors propose a theoretical model of the relationship between physical height and career success. We then test several linkages in the model based on a meta-analysis of the literature, with results indicating that physical height is significantly related to measures of social esteem (rho =.41), leader emergence (rho =.24), and performance (rho =.18). Height was somewhat more strongly related to success for men (rho =.29) than for women (rho =.21), although this difference was not significant. Finally, given that almost no research has examined the relationship between individuals' physical height and their incomes, we present four large-sample studies (total N = 8,590) showing that height is positively related to income (beta =.26) after controlling for sex, age, and weight. Overall, this article presents the most comprehensive analysis of the relationship of height to workplace success to date, and the results suggest that tall individuals have advantages in several important aspects of their careers and organizational lives.

Assessment of alternative disposal methods to reduce greenhouse gas emissions from municipal solid waste in India.

PubMed

Yedla, Sudhakar; Sindhu, N T

2016-06-01

Open dumping, the most commonly practiced method of solid waste disposal in Indian cities, creates serious environment and economic challenges, and also contributes significantly to greenhouse gas emissions. The present article attempts to analyse and identify economically effective ways to reduce greenhouse gas emissions from municipal solid waste. The article looks at the selection of appropriate methods for the control of methane emissions. Multivariate functional models are presented, based on theoretical considerations as well as the field measurements to forecast the greenhouse gas mitigation potential for all the methodologies under consideration. Economic feasibility is tested by calculating the unit cost of waste disposal for the respective disposal process. The purpose-built landfill system proposed by Yedla and Parikh has shown promise in controlling greenhouse gas and saving land. However, these studies show that aerobic composting offers the optimal method, both in terms of controlling greenhouse gas emissions and reducing costs, mainly by requiring less land than other methods. © The Author(s) 2016.

Publications in PubMed on Ebola and the 2014 outbreak

PubMed Central

Ballabeni, Andrea; Boggio, Andrea

2015-01-01

In this research note we examine the biomedical publication output about Ebola in 2014. We show that the volume of publications has dramatically increased in the past year. In 2014 there have been over 888 publications with ‘ebola’ or ‘ebolavirus’ in the title, approximately 13 times the volume of publication of 2013. The rise reflects an impressive growth starting in the month of August, concomitant with or following the surge in infections, deaths and coverage in news and social media. Though non-research articles have been the major contributors to this growth, there has been a substantial increase in original research articles too, including many papers of basic science. The United States has been the country with the highest number of research articles, followed by Canada and the United Kingdom. We present a comprehensive set of charts and facts that, by describing the volumes and nature of publications in 2014, show how the scientific community has responded to the Ebola outbreak and how it might respond to future similar global threats and media events. This information will assist scholars and policymakers in their efforts to improve scientific research policies with the goal of maximizing both public health and knowledge advancement. PMID:26539291
