INVESTIGACION CLINICA was founded by the initiative of Américo Negrette, who became its first editor, and it has been published uninterruptedly since July 1960, with a quarterly frequency. The first issues consisted mainly of a collection of reviews of seminars held at the now called Instituto de Investigaciones Clínicas "Dr. Américo Negrette", Facultad de Medicina, Universidad del Zulia, its publisher. Very soon, original research results from this institution were included in the novel journal. In the 60's, papers on results obtained during the outbreaks of Venezuelan Equine Encephalitis present in the area, were prominent. Originally, the journal published 3-4 papers, but due to the increased number of contributions, in 2001, its format changed from 1/16 to 1/8, and now each number includes 11 original articles. Currently, INVESTIGACION CLINICA publishes 44 papers a year, in Spanish or English on different biomedical topics, from contributors all around the world. Progressively it has been included in different renowned indexes, such as PubMed/MEDLINE, Science Citation Index Expanded, Excerpta Medica, Tropical Diseases Bulletin, Copernicus, Scopus, Periodica, and several others. Besides, it can be found in open access through www.Scielo.org.ve, www.freemedicaljournals.com and in our new Web page: https://sites. google.com/site/revistainvestigacionesclinicas/home. Most papers published in INVESTIGACION CLINICA have been cited in the regional or foreign literature accumulating more than 1200 citations by now. For this particular issue, to celebrate the 50th anniversary of INVESTIGACION CLINICA, we have invited some of our more recent referees or authors to contribute with Reviews in their respective areas of expertise.

Several indicators have been used to analyze scientific journals, with the impact factor and the number of citations in a 2-yr calendar time frame (2-YRC) being the most common factors. However, considering that the Journal of Applied Physiology (JAPPL) appears monthly and that calculations of these indicators are based on citations of papers published in previous years, we hypothesized that articles published at the beginning of the year would be cited more in the 2-YRC compared with those appearing in the last issues of the year, a phenomena known as a relative age effect. Our objective was to confirm the existence of a relative age effect in the 2-YRC for original articles published in JAPPL. From 2005 to 2008, a total of 1,726 original articles were published, according to the Web of Science, and 9,973 citations in 2-YRC, varying from 0 to 45, with a mean of 5.78 for individual papers. Although there were no differences in the number of original articles published in a given month (P = 0.99), the 2-YRC varied considerably throughout the year, being higher for those earlier issues of the year, as shown by the linear regression analysis (r(2) = 0.76; P < 0.001). The 2-YRC began at 6.62 during the first 3 mo of the year, dropping by 10% at each 3-mo period. In summary, the longer an article has been out there, the more citations it collects. The relative age effect is a potential confounding variable for the assessment and interpretation of 2-YRC (using calendar years) from JAPPL original articles.

To investigate the dynamics of indexing the Journal of the Balkan Union of Oncology (JBUON) in important biomedical databases, the effects on the quantity and type of published articles, and also the countries of the (co)authors of these papers. The process of the JBUON indexing started with EMBASE/Excerpta Medica, followed in 2006 (PUBMED/MEDLINE) and continued every second year in other important biomedical databases, until 2012 when JBUON became Open Access Journal (for even more information please visit www.jbuon.com). Including the next two years for monitoring the effect of the last indexing, we analyzed 9 volumes consisting of 36 issues that were published from January 2006 to December 2014, with regard to the number and category of articles, the contribution of authors from Balkan and non-Balkan countries, and the (co)authorship in the published articles. In the period 2006-2014, 1165 articles of different categories were published in J BUON. The indexing progress of JBUON immediately increased the submission rate, and enlarged the number of publications, original papers in particular, in every volume of JBUON. Authors from Balkan countries contributed in 80.7% of all articles. The average number of coauthors per original article grew slowly and was higher at the end of the investigated period than at the start (6.6 and 5.8, respectively). The progressing covering of JBUON in important biomedical databases and its visibility on international level attracted the attention of a large readership, and submission rate and the number of published articles grew significantly, particularly the number of original papers. This is the most important consequence of the editorial policy which will hopefully lead to even more progress of JBUON in the near future.

Background: This is an analysis of papers published by Iranian neurosurgeons while working in Iran until the year 2010. Methods: We collected bibliometric data and assigned a level of evidence (LOE) for each paper and compared neurosurgical research productivity across three time periods (before 1990, between 1991 and 2000, and after 2000). For further illustration, the annual growth rates of Iranian publications were calculated for all papers published after 1995. Results: We found a total of 1196 papers by 422 Iranian neurosurgeons. Five authors accounted for 22.9% of the papers. The average number of authors for each published manuscript was 3.48 and increased significantly from 2.0 to 4.0 across the three investigated periods (P < 0.001). 58.9% of Iranian papers were published in local journals only. A total of 74.6% articles were published after 2000, which was a significant increase compared with the decades before (P < 0.001). Original articles and case reports accounted for 63.8% and 31.1% of the publications, respectively. The proportion of case reports decreased while the proportion of original articles increased across the three time periods (P < 0.001). The adjusted growth rate for the total number of publications, original articles, case reports, clinical trials, and randomized clinical trials (RCTs) were 14.4%, 16.6%, 10.7%, 13.46%, and 14.7% per year, respectively. Overall, the four most frequently investigated topics were spine (27.3%), trauma (22.3%), tumor (19.1%), and vascular diseases (13.5%). The mean impact factor for journals publishing these studies and average number of citations for each paper (obtained from web of science) were found to be 1.2 and 5.46, respectively. A partitioning of these publications into assigned categories reflecting the LOE of each paper yielded the following LOE distribution for all assessed publications: Ib: 6.02%, Ic: 0.3%, IIa: 0.2%, IIb: 5.4%, IIc: 0.41%, IIIb: 4.8%, IV: 22.5%, and V: 1.2%. The relative number of publications categorized into higher LOE classes increased over the three investigated periods (P = 0.003). Based on growth curve model, the rate of increase in total numbers of publications following each position change from nonuniversity affiliated neurosurgeon to university affiliated and from university affiliated neurosurgeon to chairman university affiliated neurosurgeon was 81%. Conclusions: A considerable increase in amount and quality of Iranian papers was observed during the past decade as reflected in a higher number of papers categorized in upper LOE classes.

Recent original scientific contributions published in selected Brazilian periodicals and classifiable under cardiovascular and pulmonary subject categories cover a wide range of sub specialties, both clinical and exprimental. Because they appear in journals with only recently enhanced visibility, we have decided to highlight a number of specific items appeared in four Brazilian journals, because we understand that this is an important subsidy to keep our readership adequately informed. These papers cover extensive sub-areas in both fields. PMID:22189744

How to reduce scientific irreproducibility: the 5-year reflection.

PubMed

Fiala, Clare; Diamandis, Eleftherios P

2017-10-26

We discuss in depth six causes of scientific irreproducibility and their ramifications for the clinical sciences: fraud, unfounded papers published by prominent authorities, bias, technical deficiencies, fragmented science and problems with big data. Some proposed methods to combat this problem are briefly described, including an effort to replicate results from some high impact papers and a proposal that authors include detailed preclinical data in papers with supposedly high translational value. We here advocate for a 5-year reflection on papers with seemingly high clinical/translational potential, published alongside the original paper where authors reflect on the quality, reproducibility and impact of their findings. These reflections can be used as a benchmark for credibility, and begin a virtuous cycle of improving the quality of published findings in the literature.

The increased number of articles published in nutrition is a reflection of the relevance to scientific community. The characteristics and quality of nutritional studies determine whether readers can obtain valid conclusions from them, as well as their usefulness for evidence-based strategic policies. To determine the characteristics of papers published in nutrition journals. Descriptive study design. We reviewed 330 original papers published between January-June 2007. From: American Journal of Clinical Nutrition (AJCN), Journal of Nutrition, European Journal Nutrition, European Journal of Clinical Nutrition and Public Health Nutrition. We classified them according to the subjects studied; risk factors, study design and country of origin. Almost half the papers studied healthy people (53.3%). The most frequent illness was obesity (13.9%). Food consumption is the most frequent risk factor (63.3%). Social factors appear exclusively only in 3.6% of the papers. Clinical trials were the most common analytical design (31.8%), mainly in the AJCN (45.6%). Cross-sectional studies were the most frequent type of observational design (37.9%). Ten countries produced over half of the papers (51.3%). The US publishes the highest number of papers (20.6%), whilst developing countries make only scarce contributions to scientific literature on nutrition. Most of the papers had inferential power. They generally studied both healthy and sick subjects, coinciding with the aims of international scientific policies. However, the topics covered reflect a clear bias, prioritizing problems pertaining to developed countries. Social determinants of health should also be considered, along with behavioral and biological risk factors.

Realizing the Living Paper using the ProvONE Model for Reproducible Research

Science has advanced through traditional publications that codify research results as a permenant part of the scientific record. But because publications are static and atomic, researchers can only cite and reference a whole work when building on prior work of colleagues. The open source software model has demonstrated a new approach in which strong version control in an open environment can nurture an open ecosystem of software. Developers now commonly fork and extend software giving proper credit, with less repetition, and with confidence in the relationship to original software. Through initiatives like 'Beyond the PDF', an analogous model has been imagined for open science, in which software, data, analyses, and derived products become first class objects within a publishing ecosystem that has evolved to be finer-grained and is realized through a web of linked open data. We have prototyped a Living Paper concept by developing the ProvONE provenance model for scientific workflows, with prototype deployments in DataONE. ProvONE promotes transparency and openness by describing the authenticity, origin, structure, and processing history of research artifacts and by detailing the steps in computational workflows that produce derived products. To realize the Living Paper, we decompose scientific papers into their constituent products and publish these as compound objects in the DataONE federation of archival repositories. Each individual finding and sub-product of a reseach project (such as a derived data table, a workflow or script, a figure, an image, or a finding) can be independently stored, versioned, and cited. ProvONE provenance traces link these fine-grained products within and across versions of a paper, and across related papers that extend an original analysis. This allows for open scientific publishing in which researchers extend and modify findings, creating a dynamic, evolving web of results that collectively represent the scientific enterprise. The Living Paper provides detailed metadata for properly interpreting and verifying individual research findings, for tracing the origin of ideas, for launching new lines of inquiry, and for implementing transitive credit for research and engineering.

The Republic of Ireland has always had an influence on medicine and has produced many renowned doctors who have helped shape its history. Furthermore, many clinical articles that have originated from Ireland have changed clinical practice throughout the world. The Irish have also had an impact on the plastic surgery literature yet it has never specifically been analyzed before. The purpose of this study was to identify and analyze all papers that have originated from the plastic surgery units in the Republic of Ireland in the medical literature over the past 21 years. Twenty-four well-known plastic surgery, hand surgery and burns journals were selected for this study. By utilizing Scopus, the largest abstract and citation database of peer-reviewed literature, we analyzed each of our chosen 24 journals looking for Irish publications. Each paper was examined for article type, authorship, year of publication, institution of origin and level of evidence. Papers from the Republic of Ireland were published in 20 of the 24 journals over the past 21 years. A total of 245 articles from Ireland were published in the plastic surgery, hand surgery and burns literature over the 21-year period. Of these, 111 were original articles and 73 were case reports. The institution that published the most papers over the past 21 years was University Hospital Galway (66 publications) followed by Cork University Hospital with 54 papers. The journal with the most Irish articles was the Journal of Plastic, Reconstructive and Aesthetic Surgery with 56 papers. 2014 was the year with the most publications (28 papers). Authorship numbers also increased over time as the average number of authors in 1994 was 3.5, whereas it was 5.54 in 2014. The number of publications per year continues to increase along with authorship numbers. This mirrors the trend in other specialties. Publications are now no longer required for selection on to a higher surgical training scheme. There is now a fear that the academic output of trainees will decrease as a consequence. To prevent this, each unit must actively support and encourage research activity with their trainees.

Over the past 50 years, there has been a significant increase in published articles in the medical literature. The aesthetic surgery literature is vast, consisting of a plethora of diverse articles written by a myriad of illustrious authors. Despite this considerable archive of published material, it remains nebulous as to which precise papers have had the greatest impact on our specialty. The aim of our study was to identify and analyse the characteristics of the top 50 papers in the field of aesthetic surgery in the published literature. The 50 most cited papers were identified in several surgical journals through the Web of Science. The articles were ranked in order of the number of citations received. These classic 50 papers were analysed for article type, their journal distribution, level of evidence as well as geographic and institutional origin. Six journals contributed to the top 50 papers in aesthetic surgery with Plastic and Reconstructive Surgery contributing the most with 31 papers.

Concentration of the Most-Cited Papers in the Scientific Literature: Analysis of Journal Ecosystems

PubMed Central

Ioannidis, John P. A.

2006-01-01

Background A minority of scientific journals publishes the majority of scientific papers and receives the majority of citations. The extent of concentration of the most influential articles is less well known. Methods/Principal Findings The 100 most-cited papers in the last decade in each of 21 scientific fields were analyzed; fields were considered as ecosystems and their “species” (journal) diversity was evaluated. Only 9% of journals in Journal Citation Reports had published at least one such paper. Among this 9%, half of them had published only one such paper. The number of journals that had published a larger number of most-cited papers decreased exponentially according to a Lotka law. Except for three scientific fields, six journals accounted for 53 to 94 of the 100 most-cited papers in their field. With increasing average number of citations per paper (citation density) in a scientific field, concentration of the most-cited papers in a few journals became even more prominent (p<0.001). Concentration was unrelated to the number of papers published or number of journals available in a scientific field. Multidisciplinary journals accounted for 24% of all most-cited papers, with large variability across fields. The concentration of most-cited papers in multidisciplinary journals was most prominent in fields with high citation density (correlation coefficient 0.70, p<0.001). Multidisciplinary journals had published fewer than eight of the 100 most-cited papers in eight scientific fields (none in two fields). Journals concentrating most-cited original articles often differed from those concentrating most-cited reviews. The concentration of the most-influential papers was stronger than the already prominent concentration of papers published and citations received. Conclusions Despite a plethora of available journals, the most influential papers are extremely concentrated in few journals, especially in fields with high citation density. Existing multidisciplinary journals publish selectively most-cited papers from fields with high citation density. PMID:17183679

Quantifying reproducibility in computational biology: the case of the tuberculosis drugome.

How easy is it to reproduce the results found in a typical computational biology paper? Either through experience or intuition the reader will already know that the answer is with difficulty or not at all. In this paper we attempt to quantify this difficulty by reproducing a previously published paper for different classes of users (ranging from users with little expertise to domain experts) and suggest ways in which the situation might be improved. Quantification is achieved by estimating the time required to reproduce each of the steps in the method described in the original paper and make them part of an explicit workflow that reproduces the original results. Reproducing the method took several months of effort, and required using new versions and new software that posed challenges to reconstructing and validating the results. The quantification leads to "reproducibility maps" that reveal that novice researchers would only be able to reproduce a few of the steps in the method, and that only expert researchers with advance knowledge of the domain would be able to reproduce the method in its entirety. The workflow itself is published as an online resource together with supporting software and data. The paper concludes with a brief discussion of the complexities of requiring reproducibility in terms of cost versus benefit, and a desiderata with our observations and guidelines for improving reproducibility. This has implications not only in reproducing the work of others from published papers, but reproducing work from one's own laboratory.

The purpose of our study was to describe the dissemination of research into the clinical nursing literature. The literature provides a means of transferring knowledge from a research study through citations of the work by other authors. This was a citation analysis study to explore the dissemination of research into the clinical nursing literature, beginning with the publication of an original research study and including all of the citations to that article through 2009. The authors searched five academic nursing research journal titles, using CINAHL, for original research reports that had clinical relevance and were published between 1990-1999. The search process yielded a final data set of 28 research articles. For each of the articles, the authors searched three databases, CINAHL, Web of Science(®) and Google Scholar, to determine the citation patterns from the date of publication to August 2009. All of the research studies were cited in articles published in clinical journals although there was a wide range in the number of citations, from 3-80. The 28 research articles had a total of 759 citations; 717 (94.5%) of those citations were in articles published in clinical nursing journals. The median length of time between publication of the original study and the first citation was 1.5 years. Some of the studies were still being cited for 18 years after publication of the original work. All of the original research reports examined in this study were cited in articles in clinical journals, disseminating the research beyond the original work to reach clinicians. Clinical nursing journals keep readers up-to-date and informed about new practices in nursing and serve another important role: they disseminate research that is clinically relevant by publishing original studies and papers that cite research reports. © 2010 Blackwell Publishing Ltd.

To analyze the highly cited malaria papers published in Chinese journals from 2006 to 2013, so as to provide the evidence for formulating the plan of selecting topics to the journal editors. The published articles related to malaria included in CNKI and Wanfang medical network from 2006 to 2013 were collected, and the highly cited papers were selected according to the citation frequency calculated by Price's formula. Then the characteristics of the highly cited papers were analyzed. From 2006 to 2013, a total of 1 976 published papers related to malaria were searched in Chinese journals and 98 papers of them were selected as highly cited papers. In the highly cited papers, 18 papers were published in China Tropical Medicine , and 16 and 15 papers were published in Chinese Journal of Parasitology and Parasitic Diseases and Chinese Journal of Schistosomiasis Control , respectively; and original articles accounted for 42.86%; the first authors of these papers were from 44 institutions, and 40.91% of them were from centers for disease control and prevention (CDCs); a percentage of 22.45% of the highly cited papers received fund programs, and most of them were national or provincial funds. The research hotspots were focused on the epidemiology and control, and epidemic situation of malaria. The highly cited papers related to malaria are mainly from CDCs and research institutions, and the related journals could use this information to chose topics and solicit contributions to improve their influence.

Numerous vaccines are being actively developed for use in dermatologic diseases. Advances in the fields of immunotherapy, genetics and molecular medicine have allowed for the design of prophylactic and therapeutic vaccines with immense potential in managing infections and malignancies of the skin. This review addresses the different vaccines available for use in dermatological diseases and those under development for future potential use. The major limitation of our review is its complete reliance on published data. Our review is strictly limited to the availability of published research online through available databases. We do not cite any of the authors' previous publications nor have we conducted previous original research studies regarding vaccines in dermatology. Strength would have been added to our paper had we conducted original studies by our research team regarding the candidate vaccines delineated in the paper.

2009-06-01

We present facsimiles of some of the scientifically and historically most relevant papers published in Astronomische Nachrichten/Astronomical Notes (AN) between 1821 and 1938. Almost all of these papers were written and printed in German and it is sometimes not completely straightforward to find these original works and then to cite the historically correct version, e.g. in case of a series of articles or editorial letters. It was common during the early years that many contributions were made in form of letters to the editor. We present a summary for these original works with an English translation of their titles. Among the highlights are the originals of the discovery of stellar parallaxes by Friedrich Wilhelm Bessel, the discovery of the solar cycle by Heinrich Schwabe, the discovery of the planet Neptune by Johann Gottfried Galle, the first ever measured stellar radial velocity by Hermann Vogel, the discovery of radio emission from the Sun by Wilsing and Scheiner, the first ever conducted photoelectric photometry of stars by Paul Guthnick and up to the pioneering work by Karl Schwarzschild, Ejnar Hertzsprung, Erwin Finlay Freundlich and others. As a particular gimmick we present the still world record holding shortest paper ever published; by Johannes Hartmann in AN 226, 63 (1926) on Nova Pictoris. Our focus is on contributions in the early years and published until 1938 near the verge of the second world war.

Adaptation: a contemporary view, revisiting Crichton-Miller's 1925 paper.

PubMed

Music, Graham

2016-03-01

In this paper I discuss a contemporary 'take' on the concept of adaptation in light of Crichton-Miller's original 1926 paper. I look briefly at some of the ways that contemporary thinking is both similar to and different from ideas of 90 years ago. In particular I think about how recent neurobiological findings, epigenetic research and attachment theory have cast new light on our understanding of the ways humans adapt to social and emotional environments. It looks at how psychiatric presentations which are seen as maladaptive might well have an adaptive origin in early life. In this account I emphasise how a more modern version of evolutionary theory can be developed, particularly one influenced by life history theory, and suggest that such ideas have powerful explanatory power as well as being based solidly in good research.

Shuval, Kerem; Harker, Karen; Roudsari, Bahman; Groce, Nora E.; Mills, Britain; Siddiqi, Zoveen; Shachak, Aviv

2011-01-01

Background Qualitative research appears to be gaining acceptability in medical journals. Yet, little is actually known about the proportion of qualitative research and factors affecting its publication. This study describes the proportion of qualitative research over a 10 year period and correlates associated with its publication. Design A quantitative longitudinal examination of the proportion of original qualitative research in 67 journals of general medicine during a 10 year period (1998–2007). The proportion of qualitative research was determined by dividing original qualitative studies published (numerator) by all original research articles published (denominator). We used a generalized estimating equations approach to assess the longitudinal association between the proportion of qualitative studies and independent variables (i.e. journals' country of publication and impact factor; editorial/methodological papers discussing qualitative research; and specific journal guidelines pertaining to qualitative research). Findings A 2.9% absolute increase and 3.4-fold relative increase in qualitative research publications occurred over a 10 year period (1.2% in 1998 vs. 4.1% in 2007). The proportion of original qualitative research was independently and significantly associated with the publication of editorial/methodological papers in the journal (b = 3.688, P = 0.012); and with qualitative research specifically mentioned in guidelines for authors (b = 6.847, P<0.001). Additionally, a higher proportion of qualitative research was associated only with journals published in the UK in comparison to other countries, yet with borderline statistical significance (b = 1.776, P = 0.075). The journals' impact factor was not associated with the publication of qualitative research. Conclusions Despite an increase in the proportion of qualitative research in medical journals over a 10 year period, the proportion remains low. Journals' policies pertaining to qualitative research, as expressed by the appearance of specific guidelines and editorials/methodological papers on the subject, are independently associated with the publication of original qualitative research; irrespective of the journals' impact factor.

To describe the academic impact of publications from National Institute of Parasitic Diseases (NIPD), Chinese Center for Disease Control and Prevention, so as to give the quantity evidence for scientific research decision making. The SCIE papers of NIPD published from 2011-2015 were searched and statistically analyzed. The number of published papers, citation frequencies, h-index, and funding resources were analyzed. The academic impact of the institute was assessed according to these data. A total of 361 papers were published by NIPD, and the quantity increased year by year. The majority type is original articles. The total citations were 1 641 times, the average citation per paper was 5.19 and h-index was 17. The majority of these papers were published in foreign professional periodicals, whose impact factors were between 1.194 and 6.751. The major resources of NIPD were from China, and NIPD also had good collaborations with institutions in US and Switzerland. In China and Asia, NIPD led the research in the field of parasitology and tropical medicine. The quantity and quality of annual published papers of NIPD are on the rise. However, NIPD lagged behind the leading institutions in the world.

To identify the 100 most cited papers in cataract surgery, we performed a comprehensive bibliometric analysis basing on the literature search on the Thomson Reuters Web of Knowledge. The number of citations, including the total citations, latest 5y citations and average citation number per year (ACY), authorship, year of publication, major topics, journal of publication, country and institution of origin of each paper were recorded and then analyzed. Pearson's correlation analysis was conducted to evaluate the correlation between the published year and the number of citations. The correlation between journal's impact factor (IF) and number of citations was assessed as well. The most cited paper was the classic paper done by the European Society of Cataract & Refractive Surgeons (ESCRS) group. This paper focused on the topic of endophthalmitis. Not only the most cited papers originated from the USA, but also some American institutions like Johns Hopkins University, Harvard Medical School, etc. had the most citations. Pearson's correlation analysis indicated that the latest 5y citations and ACY were significantly related with the published year (5y citations: r =0.615, P <0.001; ACY: r =0.657, P <0.001), whereas no association between the total number of citations and published year was found ( r =0.045). Moreover, the IFs of journals were found to have no significant effect on the number of total citations. To our knowledge, this is the first study on the most influential papers in cataract surgery after a comprehensive research of relevant literatures. The present work may provide us concise information concerning the development history of cataract surgery over the past 66y.

Data compression is crucial in effective handling of genomic data. Among several recently published algorithms, ERGC seems to be surprisingly good, easily beating all of the competitors. We evaluated ERGC and the previously proposed algorithms GDC and iDoComp, which are the ones used in the original paper for comparison, on a wide data set including 12 assemblies of human genome (instead of only four of them in the original paper). ERGC wins only when one of the genomes (referential or target) contains mixed-cased letters (which is the case for only the two Korean genomes). In all other cases ERGC is on average an order of magnitude worse than GDC and iDoComp. sebastian.deorowicz@polsl.pl, iochoa@stanford.edu Supplementary data are available at Bioinformatics online. © The Author 2015.

This article describes the methodology of preparation, writing and publishing scientific papers in biomedical journals. given is a concise overview of the concept and structure of the System of biomedical scientific and technical information and the way of biomedical literature retreival from worldwide biomedical databases. Described are the scientific and professional medical journals that are currently published in Bosnia and Herzegovina. Also, given is the comparative review on the number and structure of papers published in indexed journals in Bosnia and Herzegovina, which are listed in the Medline database. Analyzed are three B&H journals indexed in MEDLINE database: Medical Archives (Medicinski Arhiv), Bosnian Journal of Basic Medical Sciences and Medical Gazette (Medicinki Glasnik) in 2010. The largest number of original papers was published in the Medical Archives. There is a statistically significant difference in the number of papers published by local authors in relation to international journals in favor of the Medical Archives. True, the Journal Bosnian Journal of Basic Medical Sciences does not categorize the articles and we could not make comparisons. Journal Medical Archives and Bosnian Journal of Basic Medical Sciences by percentage published the largest number of articles by authors from Sarajevo and Tuzla, the two oldest and largest university medical centers in Bosnia and Herzegovina. The author believes that it is necessary to make qualitative changes in the reception and reviewing of papers for publication in biomedical journals published in Bosnia and Herzegovina which should be the responsibility of the separate scientific authority/ committee composed of experts in the field of medicine at the state level.

The original article from which these excerpts were taken, "Some Hints to the Nurse Who Seeks to Become a Successful Partner in the Community Health Program," by Mary Margaret Muckley, was published the 1923 volume of the original Public Health Nursing journal. The paper listed practical pointers to nurses wanting to work in the area of public or community health nursing. The author's advice involved personal attributes, professional engagement, skills, effective organization, and community relations. Much of the original article contained sound advice for aspirants to nursing work in community settings, but some advice may be considered too idealistic even for this optimistic time period. While the particular references to organizations and agencies existing in Helena, Montana have been omitted, the nurse reading the paper in 1923 had a general guide to her key stakeholders. The excerpts from this paper may give contemporary readers an appreciation of the endurance of what Muckley terms the public health nurse's "Valuable Assets."

2010-02-01

The objective of this study was to analyze and record the published evidence regarding community pharmacy practice in India during the past decade (1998-2008). A bibliometric review analysis of the original papers was undertaken to assess the different aspects of community pharmacy practice in India. The MEDLINE, Index Copernicus, IndMed, DOAJ databases and the journals such as Indian Journal of Pharmaceutical Sciences and Indian Journal of Hospital Pharmacy were used as data sources. Type of papers, type of journals, category of papers, production indicators and impact factor of the journals were analyzed. Thirty papers were included in the study. The papers were published in 13 different journals, 33.3% of them being in the Indian Journal of Hospital Pharmacy. The average number of authors per paper was 2.73 (SD=1.41). Impact factor was available for only three journals. There are limited studies being published in India which cover the community pharmacy related activities in India. The key indicators which emerge from the literature review present some fundamental challenges to the development of the role of the community pharmacist in India.

Aniszewski, Wojciech

2016-12-01

In this paper, a specific subgrid term occurring in Large Eddy Simulation (LES) of two-phase flows is investigated. This and other subgrid terms are presented, we subsequently elaborate on the existing models for those and re-formulate the ADM-τ model for sub-grid surface tension previously published by these authors. This paper presents a substantial, conceptual simplification over the original model version, accompanied by a decrease in its computational cost. At the same time, it addresses the issues the original model version faced, e.g. introduces non-isotropic applicability criteria based on resolved interface's principal curvature radii. Additionally, this paper introduces more throughout testing of the ADM-τ, in both simple and complex flows.

Darwin's Influence on Mendel: Evidence from a New Translation of Mendel's Paper.

PubMed

Fairbanks, Daniel J; Abbott, Scott

2016-10-01

Gregor Mendel's classic paper, Versuche über Pflanzen-Hybriden (Experiments on Plant Hybrids), was published in 1866, hence 2016 is its sesquicentennial. Mendel completed his experiments in 1863 and shortly thereafter began compiling the results and writing his paper, which he presented in meetings of the Natural Science Society in Brünn in February and March of 1865. Mendel owned a personal copy of Darwin's Origin of Species, a German translation published in 1863, and it contains his marginalia. Its publication date indicates that Mendel's study of Darwin's book could have had no influence while he was conducting his experiments but its publication date coincided with the period of time when he was preparing his paper, making it possible that Darwin's writings influenced Mendel's interpretations and theory. Based on this premise, we prepared a Darwinized English translation of Mendel's paper by comparing German terms Mendel employed with the same terms in the German translation of Origin of Species in his possession, then using Darwin's counterpart English words and phrases as much as possible in our translation. We found a substantially higher use of these terms in the final two (10th and 11th) sections of Mendel's paper, particularly in one key paragraph, where Mendel reflects on evolutionary issues, providing strong evidence of Darwin's influence on Mendel.

In response, the World Health Organization (WHO) has declared the Ebola outbreak in West Africa as a "Public Health Emergency of International Concern". A small proportion of scientific literature is dedicated to Ebola research. To identify global research trends in Ebola research, the Institute for Scientific Information (ISI) Web of Science™ database was used to search for data, which encompassed original articles published from 1900 to 2013. The keyword "Ebola" was used to identify articles for the purposes of this review. In order to include all published items, the database was searched using the Basic Search method. The earliest record of literature about Ebola indexed in the Web of Science is from 1977. A total of 2477 publications on Ebola, published between 1977 and 2014 (with the number of publications increasing annually), were retrieved from the database. Original research articles (n = 1623, 65.5%) were the most common type of publication. Almost all (96.5%) of the literature in this field was in English. The USA had the highest scientific output and greatest number of funding agencies. Journal of Virology published 239 papers on Ebola, followed by Journal of Infectious Diseases and Virology, which published 113 and 99 papers, respectively. A total of 1911 papers on Ebola were cited 61,477 times. This analysis identified the current state of research and trends in studies about Ebola between 1977 and 2014. Our bibliometric analysis provides a historical perspective on the progress in Ebola research.

Introduction to positivism, interpretivism and critical theory.

PubMed

Ryan, Gemma

2018-03-16

There are three commonly known philosophical research paradigms used to guide research methods and analysis: positivism, interpretivism and critical theory. Being able to justify the decision to adopt or reject a philosophy should be part of the basis of research. It is therefore important to understand these paradigms, their origins and principles, and to decide which is appropriate for a study and inform its design, methodology and analysis. To help those new to research philosophy by explaining positivism, interpretivism and critical theory. Positivism resulted from foundationalism and empiricism; positivists value objectivity and proving or disproving hypotheses. Interpretivism is in direct opposition to positivism; it originated from principles developed by Kant and values subjectivity. Critical theory originated in the Frankfurt School and considers the wider oppressive nature of politics or societal influences, and often includes feminist research. This paper introduces the historical context of three well-referenced research philosophies and explains the common principles and values of each. The paper enables nurse researchers to make informed and rational decisions when embarking on research. ©2018 RCN Publishing Company Ltd. All rights reserved.

Strehl, Letícia; Calabró, Luciana; Souza, Diogo Onofre; Amaral, Lívio

2016-01-01

In recent decades, we have observed an intensification of science, technology and innovation activities in Brazil. The increase in production of scientific papers indexed in international databases, however, has not been accompanied by an equivalent increase in the impact of publications. This paper presents a methodology for analyzing production and the impact of certain research areas in Brazil related to two aspects: the origin of the journals (national or foreign) and international collaboration. These two variables were selected for being of particular importance in understanding the context of scientific production and communication in countries with emerging economies. The sample consisted of papers written by Brazilian researchers in 19 subfields of knowledge published from 2002 to 2011, totaling 85,082 papers. To calculate the impact, we adopted a normalized indicator called the relative subfield citedness (Rw) using a window of 5 years to obtain measurements evaluated in 2 different years: 2007 and 2012. The data on papers and citations were collected from the Web of Science database. From the results, we note that most of the subfields have presented, from one quinquennium to another, improved performance in the world production rankings. Regarding publication in national and foreign journals, we observed a trend in the distribution maintenance of production of the subfields based on the origin of the journal. Specifically, for impact, we identified a lower Rw pattern for Brazilian papers when they were published in national journals in all subfields. When Brazilian products are published in foreign journals, we observed a higher impact for those papers, even surpassing the average global impact in some subfields. For international collaboration, we analyzed the percentage of participation of foreign researchers and the connection between collaboration and the impact of papers, especially emphasizing the distinction of hyperauthorship papers in terms of production and impact.

Citation patterns of a controversial and high-impact paper: Worm et al. (2006) "Impacts of biodiversity loss on ocean ecosystem services".

PubMed

Branch, Trevor A

2013-01-01

Citation patterns were examined for Worm et al. 2006 (Science 314:787-790), a high-impact paper that focused on relationships between marine biodiversity and ecosystem services. This paper sparked much controversy through its projection, highlighted in the press release, that all marine fisheries would be collapsed by 2048. Analysis of 664 citing papers revealed that only a small percentage (11%) referred to the 2048 projection, while 39% referred to fisheries collapse in general, and 40% to biodiversity and ecosystem services. The 2048 projection was mentioned more often in papers published soon after the original paper, in low-impact journals, and in journals outside of fields that would be expected to focus on biodiversity. Citing papers also mentioned the 2048 projection more often if they had few authors (28% of single-author papers vs. 2% of papers with 10 or more authors). These factors suggest that the more knowledgeable the authors of citing papers were about the controversy over the 2048 projection, the less likely they were to refer to it. A noteworthy finding was that if the original authors were also involved in the citing papers, they rarely (1 of 55 papers, 2%) mentioned the 2048 projection. Thus the original authors have emphasized the broader concerns about biodiversity loss, rather than the 2048 projection, as the key result of their study.

We review and comment original articles published in the main peer reviewed journals between September 2015 and September 2016 on hypertension, with relevance and potential impact in clinical practice. The selection of the original papers has been necessarily limited and subjective, given the extremely high volume of publications over the period. Some large clinical trials such as SPRINT, HOPE3 or PATHWAY-2, epidemiological studies, cohort studies or studies about ambulatory blood pressure evaluation are discussed. Aspects of the target blood pressure level and treatment are also discussed. In all cases, we present the new evidences on the diagnosis, evaluation and therapeutic management of hypertension published in the last year. Our goal is to motivate thorough reading of the originals that can only be commented briefy here. © 2017 SEHLELHA. Published by Elsevier España, S.L.U. All rights reserved.

Objective: The number of scientific papers is a conventional metric to measure a country’s research performance in a particular area. The aim of this survey was to demonstrate statistical information about orthodontic research published in international and national journals. Materials and Methods: Pubmed as an international and IranMedex and SID as national databases were searched between1997 and 2012. The keyword searching method was used in English and Persian. Abstracts were reviewed and unrelated articles were omitted. Data were obtained and transferred to Microsoft Excel to survey the scintometric indicators. Results: According to the defined criteria, a total of 733 papers were found showing a considerable increase. Five hundred papers (68.2%) were published in domestic journals, and 233 (31.8%) were published in PubMed indexed journals. Most of the orthodontic articles originated from Shahid Beheshti University of Medical Sciences (22.9%). The Journal of Dental School, Shahid Beheshti University of Medical Sciences published most of the national papers (27.8%) and the Australian Orthodontic Journal published the majority of international papers (9.9%) In terms of study design, 52.5% of the articles were observational and 39.4% were interventional. Conclusion: Orthodontic research production in Iran has made significant strides in the recent years and researchers should focus on the quality of the study in this field in order to apply research production in evidence base dentistry.

If you downloaded the original PDF, but are unable to access the revision, please contact SPIE Digital Library Customer Service for assistance. One of the most important areas in biometrics is matching partial fingerprints in fingerprint databases. Recently, significant progress has been made in designing fingerprint identification systems for missing fingerprint information. However, a dependable reconstruction of fingerprint images still remains challenging due to the complexity and the ill-posed nature of the problem. In this article, both binary and gray-level images are reconstructed. This paper also presents a new similarity score to evaluate the performance of the reconstructed binary image. The offered fingerprint image identification system can be automated and extended to numerous other security applications such as postmortem fingerprints, forensic science, investigations, artificial intelligence, robotics, all-access control, and financial security, as well as for the verification of firearm purchasers, driver license applicants, etc.

John F. Dewey—Tectonics Editor

Richman, Barbara T.

‘I want the journal to acquire a reputation for very rapid, fair, and accurate reviewing,’ asserted John F. Dewey, editor-in-chief of AGU's newest journal, Tectonics. Dewey said that he will rule the bimonthly, which will begin publication in February, ‘with a bit of a rod of iron’ to ensure that Tectonics is ‘where only original and important papers are published.’‘I'm going to be very strict with reviewers,’ Dewey explained in his quick British clip. ‘If the review does not come back to me within 10 days to 2 weeks, I'll review the paper myself. I'm also going to have a system whereby, if a paper needs major surgery after being refereed, it will be rejected. Papers will have to be in virtually publishable condition before they are first submitted,’ he said.

Spinal deformity is a condition that has been recognized for many millennia. There have been major advances in the treatment of spinal deformity in recent years and studies outlining new ideas can inspire others to further advance the speciality. The number of citations a paper receives may indicate the influence of that paper. It is therefore important that we evaluate and analyze the most cited works in our field. The aim of this study is to identify the 100 most cited papers relevant to spinal deformity surgery in the literature. A search through the Thomson Reuters Web of Science™ for citations related to spinal deformity surgery was performed. The number of citations, mean citation number (total number citations/years since publication), journal, authors, year of publication and country of origin of the top 100 papers was recorded. The top 100 papers were cited a combined 17,646 times, ranging from 453 to 112. The majority of papers originated from the United States (71) and were published in 20 different journals. The decade 1990-1999 was the most prolific, with 36 of the 100 papers published during this time. Papers pertaining to the management of scoliosis (49) were the most common. This study identifies the top 100 most cited papers in the field of spinal deformity surgery. While citation is not a specific marker of the scientific quality of a paper, it is a surrogate for the influence a paper has had on the orthopedic community. This list of papers provides an invaluable resource for both those in training and those actively practicing and involved in the further development of spinal deformity surgery.

The paper "The lowest surface brightness disc galaxy known' by J.I. Davies, S. Phillipps and M.J. Disney was published in Mon. Not. R. astr. Soc. (1988), 231, 69p. The declination of the object given in section 2 of the paper is incorrect and should be changed to +19^deg^48'23". Thus the object cannot be identified with GP 1444 as in the original paper. To minimize confusion we propose to refer to the low surface brightness galaxy as GP 1444A.

Objectives: The objective of this study was to analyze and record the published evidence regarding community pharmacy practice in India during the past decade (1998-2008). Methods: A bibliometric review analysis of the original papers was undertaken to assess the different aspects of community pharmacy practice in India. The MEDLINE, Index Copernicus, IndMed, DOAJ databases and the journals such as Indian Journal of Pharmaceutical Sciences and Indian Journal of Hospital Pharmacy were used as data sources. Type of papers, type of journals, category of papers, production indicators and impact factor of the journals were analyzed. Results: Thirty papers were included in the study. The papers were published in 13 different journals, 33.3% of them being in the Indian Journal of Hospital Pharmacy. The average number of authors per paper was 2.73 (SD=1.41). Impact factor was available for only three journals. Conclusions: There are limited studies being published in India which cover the community pharmacy related activities in India. The key indicators which emerge from the literature review present some fundamental challenges to the development of the role of the community pharmacist in India. PMID:23093877

[The trend and prospect of studies on the history of Western medicine in Korea.].

PubMed

Kim, Ock Joo

2010-06-30

Studies on the history of Western medicine in Korea began to be actively conducted and published since the restart of the Korean Society for the History of Medicine in 1991, which had been originally inaugurated in 1947, and the publication of its official journal, the Korean Journal of Medical History in 1992. In 1970s and 1980s, even before the start of the Journal, articles on a history of Western medicine were published mainly written by physicians in medical journals. This paper aims to provide an overview of the publications on the history of Western medicine in Korea, comparing papers published in the Journal with those published in other journals. Authors of the papers in the Journal are those who majored in history of medicine or history science whose initial educational backgrounds were medicine or science, whereas authors of the papers in other journals majored in Western history, economic history, social history, religious history, or women's history. While a large portion of papers in the Journal deal with medicine in ancient Greek or in modern America with no paper on medieval medicine, the papers in other journals deal with more various periods including ancient, medieval and modern periods and with diverse areas including France, Britain, Germany, Europe etc. Recent trends in 2000s show an increase in the number of researchers who published the history of Western medicine in other journals, total number of their publications, and the topics that they dealt with in their papers. In contrast, however, the number of researchers published in the Journal, the number of the papers and its topics - all decreased in recent years. Only three papers on the history of diseases have been published in the Journal, while eleven published in other journals. In order to stimulate research on the history of Western medicine in Korea, concerted efforts are necessary including academic communication among various disciplines, formulation of a long term plan to enlarge the pool of researchers and readers of the history of Western medicine, and development of strategic educational programs for both graduates and undergraduates including students of medicine and of humanities in Korea.

In 2007, the European Society of Physical and Rehabilitation Medicine (ESPRM) established the European Physical and Rehabilitation Medicine Journal Network (EPRMJN) with a view to increase scientific knowledge among physical and rehabilitation medicine (PRM) specialists and to foster collaboration among the national, regional (multinational) and European PRM journals. In this connection, this paper gives the readers of national and regional, and European PRM journals a complete overview of the European Journal of Physical and Rehabilitation Medicine (EJPRM), the official ESPRM journal, and a review of the papers published in 2008. The evolution of the EJPRM in the last five years was analyzed, and the papers published in 2008 were systematically reviewed and classified by content and discussed. The EJPRM is listed in PubMed and Current Contents; at now the unofficial 2008 Impact Factor is 1.14, like the Impact Factor, also the independent SCImago Journal Rate and Cites per Doc (two years) have increased steadily since 2005. The EJPRM published 72 papers in 2008, with a well balanced coverage of different rehabilitation topics. The rejection rate is around 40%; the review and publication times are 1.2 and 10.0 months, respectively. The published papers are presented here by topic, highlighting multi-journal initiatives (such as the EPRMJN and the Euro-American Focus with the American Journal of PRM), monographic Special Sections, systematic Cochrane PRM reviews, original papers and case reports, and other contents including the Internet Bookshelf. This paper represents the start of the EPRMJN collaborative efforts to increase scientific knowledge among PRM specialists in Europe, independently of the language in which papers are published.

The construction of mind, self, and society: the social process behind G. H. Mead'S social psychology.

PubMed

Huebner, Daniel R

2012-01-01

Mind, Self, and Society, the posthumously published volume by which George Herbert Mead is primarily known, poses acute problems of interpretation so long as scholarship does not consider the actual process of its construction. This paper utilizes extensive archival correspondence and notes in order to analyze this process in depth. The analysis demonstrates that the published form of the book is the result of a consequential interpretive process in which social actors manipulated textual documents within given practical constraints over a course of time. The paper contributes to scholarship on Mead by indicating how this process made possible certain understandings of his social psychology and by relocating the materials that make up the single published text within the disparate contexts from which they were originally drawn. © 2012 Wiley Periodicals, Inc.

Publication of original research, clinical experiences, and critical reviews of literature are vital to the growth of the genetic counseling field, delivery of genetic counseling services, and professional development of genetic counselors. Busy clinical schedules, lack of time and funding, and training that emphasizes clinical skills over research skills may make it difficult for new genetic counselors to turn their thesis projects into publications. This paper summarizes and elaborates upon a presentation aimed at de-mystifying the publishing process given at the 2008 National Society of Genetic Counselors Annual Education Conference. Specific topics include familiarizing prospective authors, particularly genetic counseling students, with the basics of the publication process and related ethical considerations. Former students' experiences with publishing master's theses also are described in hopes of encouraging new genetic counselors to submit for publication papers based on their thesis projects.

Here, we present a significantly improved version of our previously published method for the extraction of fungal genomic DNA from pure cultures using Whatman FTA filter paper matrix technology. This modified protocol is extremely rapid, significantly more cost effective than our original method, and importantly, substantially reduces the problem of potential cross-contamination between sequential filters when employing FTA technology.

CORRIGENDUM: Universal variational expansion for high-precision bound-state calculations in three-body systems. Applications to weakly bound, adiabatic and two-shell cluster systems

NASA Astrophysics Data System (ADS)

Bailey, David H.; Frolov, Alexei M.

2003-12-01

Since the above paper was published we have received a suggestion from T K Rebane that our variational energy, -402.261 928 652 266 220 998 au, for the 3S(L = 0) state from table 4 (right-hand column) is wrong in the fourth and fifth decimal digits. Our original variational energies were E(2000) = -402.192 865 226 622 099 583 au and E(3000) = -402.192 865 226 622 099 838 au. Unfortunately, table 4 contains a simple typographic error. The first two digits after the decimal point (26) in the published energies must be removed. Then the results exactly coincide with the original energies. These digits (26) were left in table 4 from the original version, which also included the 2S(L = 0) states of the helium-muonic atoms. A similar typographic error was found in table 4 of another paper by A M Frolov (2001 J. Phys. B: At. Mol. Opt. Phys. 34 3813). The computed ground state energy for the ppµ muonic molecular ion was -0.494 386 820 248 934 546 94 mau. In table 4 of that paper the first figure '8' (fifth digit after the decimal point) was lost from the energy value presented in this table. We wish to thank T K Rebane of the Fock Physical Institute in St Petersburg for pointing out the misprint related to the helium(4)-muonic atom.

U.S. Radioecology Research Programs of the Atomic Energy Commission in the 1950s

Reichle, D.E.

2004-01-12

This report contains two companion papers about radiological and environmental research that developed out of efforts of the Atomic Energy Commission in the late 1940s and the 1950s. Both papers were written for the Joint U.S.-Russian International Symposium entitled ''History of Atomic Energy Projects in the 1950s--Sociopolitical, Environmental, and Engineering Lessons Learned,'' which was hosted by the International Institute for Applied Systems Analysis in Laxemberg, Austria, in October 1999. Because the proceedings of this symposium were not published, these valuable historic reviews and their references are being documented as a single ORNL report. The first paper, ''U.S. Radioecology Research Programsmore » Initiated in the 1950s,'' written by David Reichle and Stanley Auerbach, deals with the formation of the early radioecological research programs at the U.S. Atomic Energy Commission's nuclear production facilities at the Clinton Engineering Works in Oak Ridge, Tennessee; at the Hanford Plant in Richland, Washington; and at the Savannah River Plant in Georgia. These early radioecology programs were outgrowths of the environmental monitoring programs at each site and eventually developed into the world renowned National Laboratory environmental program sponsored by the Office of Biological and Environmental Research of the U.S. Department of Energy. The original version of the first paper was presented by David Reichle at the symposium. The second paper, ''U.S. Atomic Energy Commission's Environmental Research Programs Established in the 1950s,'' summarizes all the environmental research programs supported by the U.S. Atomic Energy Commission in the 1950s and discusses their present-day legacies. This paper is a modified, expanded version of a paper that was published in September 1997 in a volume commemorating the 50th anniversary symposium of the U.S. Department of Energy's Office of Biological and Environmental Research (DOE/BER). Contributors to the original work--Murray Schulman, DOE Headquarters, retired; Jerry Elwood, DOE/BER; David Reichle, Oak Ridge National Laboratory; and Ward Wicker, Colorado State University--provided further insight into environmental research in the decade of the 1950s and expanded the environmental part of the original document. The original version of the second paper was presented by David Reichle in poster session at the symposium.« less

Comparative study of methods used in the RIC articles published in 3-years periods representing three decades (1972-74, 1982-84, 1992-94). Out of 273 original papers, 218 (80%) were of clinical research. There was an increased percentage of longitudinal vs cross-sectional studies, with cohort and randomized clinical trials showing the largest increase. The total number of research manuscripts also increased. The clinical research methods of the papers in the RIC have shown an increased rate of designs with a higher scientific value.

Dosimetric validation of the Acuros XB Advanced Dose Calculation algorithm: fundamental characterization in water

2011-05-01

This corrigendum intends to clarify some important points that were not clearly or properly addressed in the original paper, and for which the authors apologize. The original description of the first Acuros algorithm is from the developers, published in Physics in Medicine and Biology by Vassiliev et al (2010) in the paper entitled 'Validation of a new grid-based Boltzmann equation solver for dose calculation in radiotherapy with photon beams'. The main equations describing the algorithm reported in our paper, implemented as the 'Acuros XB Advanced Dose Calculation Algorithm' in the Varian Eclipse treatment planning system, were originally described (for the original Acuros algorithm) in the above mentioned paper by Vassiliev et al. The intention of our description in our paper was to give readers an overview of the algorithm, not pretending to have authorship of the algorithm itself (used as implemented in the planning system). Unfortunately our paper was not clear, particularly in not allocating full credit to the work published by Vassiliev et al on the original Acuros algorithm. Moreover, it is important to clarify that we have not adapted any existing algorithm, but have used the Acuros XB implementation in the Eclipse planning system from Varian. In particular, the original text of our paper should have been as follows: On page 1880 the sentence 'A prototype LBTE solver, called Attila (Wareing et al 2001), was also applied to external photon beam dose calculations (Gifford et al 2006, Vassiliev et al 2008, 2010). Acuros XB builds upon many of the methods in Attila, but represents a ground-up rewrite of the solver where the methods were adapted especially for external photon beam dose calculations' should be corrected to 'A prototype LBTE solver, called Attila (Wareing et al 2001), was also applied to external photon beam dose calculations (Gifford et al 2006, Vassiliev et al 2008). A new algorithm called Acuros, developed by the Transpire Inc. group, was built upon many of the methods in Attila, but represents a ground-up rewrite of the solver where the methods were especially adapted for external photon beam dose calculations, and described in Vassiliev et al (2010). Acuros XB is the Varian implementation of the original Acuros algorithm in the Eclipse planning system'. On page 1881, the sentence 'Monte Carlo and explicit LBTE solution, with sufficient refinement, will converge on the same solution. However, both methods produce errors (inaccuracies). In explicit LBTE solution methods, errors are primarily systematic, and result from discretization of the solution variables in space, angle, and energy. In both Monte Carlo and explicit LBTE solvers, a trade-off exists between speed and accuracy: reduced computational time may be achieved when less stringent accuracy criteria are specified, and vice versa' should cite the reference Vassiliev et al (2010). On page 1882, the beginning of the sub-paragraph The radiation transport model should start with 'The following description of the Acuros XB algorithm is as outlined by Vassiliev et al (2010) and reports the main steps of the radiation transport model as implemented in Eclipse'. The authors apologize for this lack of clarity in our published paper, and trust that this corrigendum gives full credit to Vassiliev et al in their earlier paper, with respect to previous work on the Acuros algorithm. However we wish to note that the entire contents of the data and results published in our paper are original and the work of the listed authors.

The British Journal of Oral and Maxillofacial Surgery (BJOMS) publishes many types of papers including original articles, review articles, and short communications. Many of the latter are isolated case reports of rare or interesting diseases or of difficult or unexpected complications. While case reports are sometimes considered to be of little educational or clinical value, and as such do little to advance medical knowledge, they do have an important role, and many trainees begin their publishing careers writing such papers. There is increasing pressure for space in paper medical journals and, for this reason, some journals either limit or do not publish short publications in print copy but instead put them online. Using established criteria, we previously evaluated all 142 short communications published in the BJOMS during 2008-2009 and found that 48% of them had little or no educational value. As a result, the editorial board of BJOMS took the decision to publish most short communications online only. We have now analysed 48 short communications that were published online only during 2010-2011. Most (80%) were single case reports that covered virtually the whole remit of the specialty, and over half (56%) were published by authors based in the UK. While many of these papers did not add important new information to existing knowledge, these types of article are clearly of value both for trainees and for experienced surgeons. We think that these should continue to be supported as, in addition to their educational value, they are an excellent way for trainees to start to write.

The governments and organizations responsible for scientific policies try to encourage equality of gender, among their priorities that of obtaining equal participation and full integration of women in all aspects of the scientific profession. The study analyzes the scientific production of women in the areas of Psychiatry by means of the bibliometric study of the papers published in ACTAS ESPANOLAS DE PSIQUIATRIA. A total of 458 papers published from 1999- 2006 period were downloaded from the Science Citation Index-Expanded database, these including original research papers, review articles and clinical cases. A bibliometric study broken down by gender was carried out to determine the existence or inequalities between men and women regarding scientific productivity, type of document, order of author signatures, on the institutional and geographical level. The papers were published by 1,194 different authors. The gender of 977 authors was identified, 587 (60.08%) men and 390 (39.92%) women. The percentage of women authorship has risen from 29.92% in 1999 to 38.86% in 2006. A total of 42.92% of authors having one published article were women, while (those with more than nine articles) only accounted for 33%. Bibliometric studies on scientific activity provide essential information to promote gender equality. An annual increase over 1% in the number of female authors in the journal has been observed, which if it continues will lead to a parity in coming years.

Translation of the V. I. Arnold paper "From Superpositions to KAM Theory" (Vladimir Igorevich Arnold. Selected — 60, Moscow: PHASIS, 1997, pp. 727-740)

V. I. Arnold (12 June 1937-3 June 2010) published several papers where he described, in the form of recollections, his two earliest research problems (superpositions of continuous functions and quasi-periodic motions in dynamical systems), the main results and their interrelations: [A1], then [A2] (reprinted as [A4, A6]), and [A3] (translated into English by the author as [A5]). The first exposition [A1] has never been translated into English; however, it contains many details absent in the subsequent articles. It seems therefore that publishing the English translation of the paper [A1] would not be superfluous. What follows is this translation. In many cases, the translator gives complete bibliographic descriptions of various papers mentioned briefly in the original Russian text. The English translations of papers in Russian are also pointed out where possible. A related material is contained also in Arnold's recollections "On A.N. Kolmogorov". Slightly different versions of these reminiscences were published several times in Russian and English [A7-A12]. The early history of KAM theory is also discussed in detail in the recent brilliant semi-popular book [A13].

Electronic formats (ePROs) of paper-based patient-reported outcomes (PROs) should be validated before they can be reliably used. This review aimed to examine studies investigating measurement equivalence between ePROs and their paper originals to identify methodologies used and to determine the extent of such validation. Three databases (OvidSP, Web of Science and PubMed) were searched using a set of keywords. Results were examined for compliance with inclusion criteria. Articles or abstracts that directly compared screen-based electronic versions of PROs with their validated paper-based originals, with regard to their measurement equivalence, were included. Publications were excluded if the only instruments reported were stand-alone visual analogue scales or interactive voice response formats. Papers published before 2007 were excluded, as a previous meta-analysis examined papers published before this time. Fifty-five studies investigating 79 instruments met the inclusion criteria. 53 % of the 79 instruments studied were condition specific. Several instruments, such as the SF-36, were reported in more than one publication. The most frequently reported formats for ePROs were Web-based versions. In 78 % of the publications, there was evidence of equivalence or comparability between the two formats as judged by study authors. Of the 30 publications that provided preference data, 87 % found that overall participants preferred the electronic format. When examining equivalence between paper and electronic versions of PROs, formats are usually judged by authors to be equivalent. Participants prefer electronic formats. This literature review gives encouragement to the further widespread development and use of ePROs.

Historical review of a long-overlooked paper by R. A. Daly concerning the origin and early history of the Moon

NASA Astrophysics Data System (ADS)

Baldwin, Ralph B.; Wilhelms, Don E.

1992-03-01

In 1946 the great geologist R. A. Daly published an important paper in which he discussed a great many problems concerning the Moon and its features and origin. His paper was almost completely ignored by the scientists of the day and was ``lost'' for nearly half a century. The present paper marks an attempt to outline Daly's contributions to the interpretation of these lunar problems, in particular the origin of the Moon. One of the major ideas, which probably was the incentive for him to write the paper, was that the Moon was born as a result of a very early glancing collision of the Earth and a planet-sized body. Other subjects covered are the origin of the craters from Earth fragments, although meteoritic impact is also presented; the nature of the maria as lava from the body of the Moon; and origin of the lines of small craters as produced by gas escaping from the Moon. Daly rejected all non impact models for crater origin except for the tiny gas-made aligned pits. He vigorously stated that the Moon was largely created from the body of the Earth and discussed three methods by which this could be accomplished, one internal and two external, before settling on the glancing collision model. Daly clearly was the pioneer in presenting the impact model of the origin of the Moon. Much later, works by others have modified the hypothesis, but this is only natural evolution. Two other ``lost'' papers will be mentioned to show that this is an all too frequent occurrence. In 1893 Gilbert wrote a milestone paper that was generally unrecognized for more than 50 years. He espoused the impact theory of the origin of lunar basins and craters. He was wrong about the mechanism involved, but he was right about the impact idea. Similarly, Öpik in 1916 showed that impact craters must be formed by explosions due to the high energies of striking meteorites. He showed that such impacts, even at low angles of fall would result in circular craters, thus correcting Gilbert, whom he did not mention. His paper also ``disappeared'' for many years. Early recognition and understanding of these three papers would have advanced lunar studies by many years.

The Original Michaelis Constant: Translation of the 1913 Michaelis-Menten Paper

PubMed Central

Johnson, Kenneth A.; Goody, Roger S.

2011-01-01

Nearly 100 years ago Michaelis and Menten published their now classic paper (Michaelis, L., and Menten, M. L. (1913) Die Kinetik der Invertinwirkung, Biochemische Zeitschrift 49, 333–369), in which they show that the rate of an enzyme-catalyzed reaction is proportional to the concentration of enzyme-substrate complex predicted by the Michaelis-Menten equation. Because the original text was written in German, yet is often quoted by English speaking authors, we undertook a complete translation of the 1913 publication, which we provide as an online supplement (http://pubs.acs.org). Here we introduce the translation, describe the historical context of the work, and show a new analysis of the original data. In doing so, we uncovered several surprises that reveal an interesting glimpse into the early history of enzymology. In particular, our re-analysis of Michaelis and Menten’s data using modern computational methods revealed an unanticipated rigor and precision in the original publication and uncovered a sophisticated, comprehensive analysis that has been overlooked in the century since their work was published. Michaelis and Menten not only analyzed initial velocity measurements, but they also fit their full time course data to the integrated form of the rate equations, including product inhibition, and derived a single global constant to represent all of their data. That constant was not the Michaelis constant, but rather, Vmax/Km, the specificity constant times the enzyme concentration (kcat/Km*E0). PMID:21888353

We previously showed that the number of publications in dermatology is increasing year by year, and positively correlates with improved economic conditions in mainland China, a still developing Asian country. However, the characteristics of publications in dermatology departments in more developed Asian countries such as Japan and South Korea are unknown. In the present study, publications from 2003 through 2012 in dermatology in Japan, South Korea and mainland China were characterized. All data were obtained from http://www.pubmed.com. Dermatology departments in Japan published 4,094 papers, while mainland China and South Korea published 1528 and 1,758 articles, respectively. 48% of articles from dermatology in Japan were original research and 36% were case reports; The number of publications in Japan remained stable over time, but the overall impact factors per paper increased linearly over the last 10 year period (p < 0.05). In mainland China, 67% of articles from dermatology were original research, while 19% were case reports; The number of publications and their impact factors per paper increased markedly. In South Korea, 65% of articles from dermatology were original research and 20% were case reports. The impact factors per paper remained unchanged, despite of the fact that the number of publications increased over the last 10 year period (r2 = 0.6820, p = 0.0032). Only mainland China showed a positive correlation of the number of publications with gross domestic product per capita during this study period. These results suggest that the total number of publications in dermatology correlates with economic conditions only in developing country, but not in more developed countries in Asia. The extent of economic development could determine both the publication quantity and quality.

Research is important for the development of family medicine as a professional field in primary care. The aim of this study was to suggest directions for the development of family medicine research by analyzing research trends in original papers published in the Korean Journal of Family Medicine (KJFM) and international journals. We investigated original research papers published in KJFM and 4 international journals from August 2009 to July 2010. Analysis was conducted according to research topics, authors, methods, participants, and data sources. 'Clinical research' was the most common research topic in both the KJFM (88.3%) and international journals (57.3%); however, international journals had more studies in other domains ('education and research,' 'health service,' and 'family medicine'). More authors other than family physicians participated in international journals than in the KJFM (58% and 3.3%, respectively). Most studies were 'cross-sectional' in KJFM (77.0%) and international journals (51.5%): however, the latter had more 'qualitative' studies, 'cohort' studies, and 'systematic reviews' than the former. The largest study population was 'visitors of health promotion center' in the KJFM and 'outpatients' in international journals. Most of the study sources were 'survey' and 'medical records' in both. There were limitations of diversity in the papers of the KJFM. Future investigation on papers of other than family medicine journals should be planned to assess research trends of family physicians.

Fan, XiaoMing; Gao, Ying; Ma, Bing; Xia, ZhaoFan

2016-11-01

The objective of this study was to conduct a survey of the academic contribution and influence of Chinese scholars in the field of burns. The PubMed database was searched to obtain literature items originating from various countries and Chinese provinces from 1985 to 2014. The citation data were collected through the Google Scholar engine. A total of 1037 papers published in 256 journals were included in this survey. China was second only to the USA in the number of publications on burns since 2010. In addition, the annual number of papers has increased significantly since 2001. The journal Burns published the most number of articles, but its proportion has been decreasing. Of the papers included in the survey, 58.34% were published in journals with a 5-year impact factor between 1 and 2, whereas only 3.66% were published in journals with an impact factor >5. Both total citations and citations per paper have decreased in the past decade. Randomized controlled trials or systematic reviews merely accounted for a small proportion. Twenty-nine provinces including 64 cities contributed one paper at least. The publications from Taiwan, Beijing, Chongqing, Shanghai, and Guangdong were high in both quantity and quality.

Publishing a Master’s Thesis: A Guide for Novice Authors

PubMed Central

Resta, Robert G.; McCarthy Veach, Patricia; Charles, Sarah; Vogel, Kristen; Blase, Terri

2010-01-01

Publication of original research, clinical experiences, and critical reviews of literature are vital to the growth of the genetic counseling field, delivery of genetic counseling services, and professional development of genetic counselors. Busy clinical schedules, lack of time and funding, and training that emphasizes clinical skills over research skills may make it difficult for new genetic counselors to turn their thesis projects into publications. This paper summarizes and elaborates upon a presentation aimed at de-mystifying the publishing process given at the 2008 National Society of Genetic Counselors Annual Education Conference. Specific topics include familiarizing prospective authors, particularly genetic counseling students, with the basics of the publication process and related ethical considerations. Former students’ experiences with publishing master’s theses also are described in hopes of encouraging new genetic counselors to submit for publication papers based on their thesis projects.

Food for thought: ethics case discussion as slow nourishment in a fast world.

Higgs, Roger

2015-01-01

Case discussion offers important opportunities to do good medical ethics, but do we understand what the benefits might be? This paper looks at the 'Case Conference' series in the JME, its origins and methods, examines some cases in outline, and reviews issues that arise that are not usually taken into account. Cases are harder to publish now, not least because of ethical constraints. Ways past this apparently paradoxical outcome are suggested. Published by the BMJ Publishing Group Limited.

Creationism and intelligent design are incompatible with scientific progress: A response to Shanta and Vêdanta.

PubMed

Caetano-Anollés, Gustavo

2016-01-01

In a recent opinion paper, B.K. Shanta claims science leaves no room for the subjective aspect of consciousness, and in doing so, attacks both origin of life and evolutionary research. He claims Vêdanta, one of the 6 orthodox schools of Hindu philosophy, offers an explanation: "the origin of everything material and nonmaterial is sentient and absolute." Here I discuss how the pseudoscience of these creationist views, which are aligned with Intelligent Design, are incompatible with scientific progress and should not be published in scientific journals.

The correct citation and spelling of Ptiliogonys and type locality of Ptiliogonys cinereus

USGS Publications Warehouse

Browning, M. Ralph

William Swainson published descriptions and illustrations of many new forms of New World birds. In some of his earlier papers, Swainson cited his own works (of which only some parts have been published) as well as some manuscripts that were never published (see McMillan 1971). Swainson also referred to works that were published later under different titles. For example, Swainson (1827a) listed several names of birds and cited his "Mexican Zoology," a work that was never published. Later he (Swainson 1831-1832) referred to the "Cat. of Mex. Mus. App. p. 4 (1824)," in which he claimed to have described the taxa he had listed in Swainson (1827a).Modern authorities (e.g. Greenway 1960: 371; American Ornithologists' Union [AOU] 1983: 582) refer to the 1824 source as the original publication for the genus they render as Ptilogonys and (AOU 1983) for the species Ptilogonys cinereus. However, there is no evidence that the 1824 work was ever seen as a manuscript or published. In this paper, I review the use of "Swainson, 1824," as a citation and discuss the actual publication, spelling of the names Ptiliogonys and Ptiliogonys cinereus, and type locality of the species.

This paper reports on a qualitative exploration of the reasons for differences in pathways to care and duration of untreated psychosis (DUP) in the African, Caribbean and European (ACE) Pathways to Care study from the perspective of respondents to the study and their families. Ontario, Canada. Thirty-four participants in total. Twenty-five young people who had experienced a first episode of psychosis and nine family members. Participants were part of the ACE Pathways to Care study. We implemented six focus groups. Furthermore, we implemented four in-depth interviews with two African-origin young women, one Caribbean-origin woman, and one European-origin woman with lived experience of psychosis. Factors that influenced help-seeking delays across the three groups were: personal awareness of symptoms, family members' knowledge of psychotic symptoms and knowledge of mental health services. Youth and their family members described how stigma played a key role in pathways to care by stopping them from asking for help. The way in which stigma operated on the three groups' members, from feeling ashamed to feeling guilty for their mental illnesses, helped to explain differences in DUP between the groups. Guilt feelings emerged as a prominent theme among members from the African and Caribbean groups and it was not discussed in the European focus group. Delay in entering into first-episode psychosis programmes was also influenced by the stigma perceived by young people in healthcare settings. This had an impact on the therapeutic relationships, disclosure of symptoms and overall trust in the healthcare system. The findings of this paper suggest that stigma, especially internalised stigma, may operate in different ways in European-origin, African-origin and Caribbean-origin groups. These findings could inform the development of more equitable services for people in early stages of psychosis. Published by the BMJ Publishing Group Limited.

Affiliation search of the Scopus database was performed on November 23, 2014 in order to identify published papers from the Ss Cyril and Methodius University of Skopje (UC&M), Republic of Macedonia. A total number of 3960 articles (3055 articles from UC&M, 861 articles from Faculty of Medicine, UC&M, and 144 articles from Faculty of Pharmacy, UC&M) were selected for analysis (1960-2014). SCImago Journal Rank (SJR), Source Normalized Impact per Paper (SNIP) and h-index were calculated from the Scopus database. The number of published papers was sharply increased with maximum of 379 papers in 2012 year. The largest number of papers has been published in Macedonian Journal of Medical Sciences, Journal of Molecular Structure, Lecture Notes in Computer Science, Acta Pharmecutica, and Macedonian Journal of Chemistry and Chemical Engineering. The biggest SJR and SNIP has journal Nephrology Dialysis Transplantation. First three places of the top ten authors belong to Dimirovski GM, Gavrilovska L, and Gusev M. Top three places based on Scopus h-index (total number of published papers) belong to Kocarev L, Stafilov T, and Polenakovic M. The majority of papers originate from UC&M, but significant numbers of papers are affiliated to Faculty of Medicine, Faculty of Pharmacy, and Institute of Chemistry as members of UC&M, as well as Macedonian Academy of Sciences and Arts. Articles are the most dominant type of documents followed by conference papers, and review articles. Medicine is the most represented subject. Officials of the Ss Cyril and Methodius University of Skopje should undertake more effective and proactive policies for journal publishers and their Editorial Boards in order to include more journals from UC&M in the Scopus database.

2011-01-01

Modern science is increasingly dependent on computational analysis of very large data sets. Organizing, referencing, publishing those data has become a complex problem. Published research that depends on such data often fails to cite the data in sufficient detail to allow an independent scientist to reproduce the original experiments and analyses. This paper explores some of the challenges related to data identification, equivalence and reproducibility in the domain of data intensive scientific processing. It will use the example of Earth Science satellite data, but the challenges also apply to other domains.

2013-01-01

Background China has been experiencing huge changes in all aspects including dermatologic research since its reform in 1978. However, how the economic and intellectual development has influenced the publication trends in the field of dermatology, which could mirror the scientific development in other medical disciplines, is unknown. In the present study, we analyzed the publication trends from departments of dermatology in mainland China from 2002 to 2011. Materials and Methods All publication data were obtained from www.pubmed.com. Only papers published from dermatology departments of mainland China were used for analysis. Results The number of publications increased 10-fold over this 10 year period. A total 1,231 of articles were published in English in 251 journals between 2002 and 2011. A total of 129 journals published only one paper from dermatology departments of mainland China. Over 60% of articles were original research and 21.7% were case reports. Among these 251 journals, foremost was the Journal of Clinical Experimental Dermatology, which published 5.9% of all papers from mainland China. 2.7% papers were published in the Journal of Investigative Dermatology. The number of publications positively correlated with the changes in gross domestic product per capita during the study period. Conclusions These results suggest that the number of publications in the dermatology field has increased markedly in mainland China over the last 10 years. This dramatic increase in publications could be, at least partially, attributed to the significant improvement in economic conditions in mainland China. PMID:23968296

2015-01-01

We aimed to identify the 100 top-cited articles published on chronic obstructive pulmonary disease (COPD) and to analyze their characteristics so as to provide information on the achievement and development in COPD research over the past decades. A comprehensive list of citation classics in COPD was generated by searching the Science Citation Index expanded database, using the keywords "COPD" or "chronic obstructive pulmonary disease" or "chronic obstructive pulmonary diseases". The 100 top-cited research papers were retrieved by reading the abstract or full text if needed. All eligible articles were read for basic information, including country of origin, organizations, article type, journals, research field, and authors. The 100 top-cited articles on COPD were published between 1966 and 2010. The number of citations ranged from 254 to 2,164, with a mean of 450 citations for each article. These citation classics were from 32 countries, with 38 from the United States. The Imperial College London led the list of classics, with 16 papers. The 100 top-cited articles were distributed in 18 journals, with the American Journal of Respiratory, Critical Care Medicine, and Journal of the American Medical Association topping the list. Among the various fields, both respiratory system (63%) and general internal medicine (63%) were the most common fields of study for the 100 articles. Our bibliometric analysis provides a historical perspective on the progress of scientific research on COPD. Articles originating from the United States and published in high-impact specialized respiratory journals are most likely to be cited in the field of COPD research.

Epidemiological data on urolithiasis in Spain have appeared in publications especially local and regional level, with few referrals to Spanish national territory. The aim of this paper is to review and systematize the epidemiological data published on urolithiasis in Spain. We reviewed publications in national and international scientific journals, meetings and conferences, and research reports (1977-2016). PubMed search (indexed papers) and manual bibliography search (not indexed works) were performed. Bibliometric data evaluated: Year of publication, geographic area, number of cases, sample type, study design and publishing format. Demographic systematization of data: age, age and frequency distribution by gender, family history, social stratum, profession, place of residence, ethnics, seasonality and dietary habits. Publications revised: 79 corresponding to 56 main authors. Selected publications with original data: 42 (2 composed by Part I and II, and 2 composed by paper and thesis), corresponding to 35 authors. Bibliometric and demographic data of all publications are displayed in tables, sorted by variables. The comprehensive review of studies on epidemiology in Spain constitutes a solid basis for future research about epidemiology of urolithiasis.

This study documented the trends in authorship and sampling in applied biomechanics research published in the Journal of Applied Biomechanics and ISBS Proceedings. Original research articles of the 1989, 1994, 1999, 2004, and 2009 volumes of these serials were reviewed, excluding reviews, modeling papers, technical notes, and editorials. Compared to 1989 volumes, the mean number of authors per paper significantly increased (35 and 100%, respectively) in the 2009 volumes, along with increased rates of hyperauthorship, and a decline in rates of single authorship. Sample sizes varied widely across papers and did not appear to change since 1989.

Since the first paper published in 2005 Isogeometric Analysis (IGA) has gained strong interest and found applications in many engineering problems. Despite the advancement of the method, there are still far fewer software implementations comparing to Finite Element Method. The paper presents an approach to the development of data structures that can support multi-region IGA with local mesh refinement (patch-based) and possible application in IGA-FEM models. The purpose of this paper is to share original design concepts, that authors have created while developing an IGA package, which other researchers may find beneficial for their own simulation codes.

Changing Authorship Patterns and Publishing Habits in the European Journal of Pediatric Surgery: A 10-Year Analysis.

Pintér, András

2015-08-01

The aim of this study is an analysis of the changing authorship patterns and publishing habits encountered in papers published in the European Journal of Pediatric Surgery (EJPS) over the past 10 years. Furthermore, it seeks to anticipate the trends in the years ahead. We conducted a retrospective review of articles published in the EJPS during a 10-year period (January 1, 2003-December 31, 2012). Each article was classified as an Original Report/Original Article (OR/OA) or as a Case Report/Case Gallery (CR/CG), and they were analyzed separately. For investigation of the percentage distribution of publications according to the number of authors per articles, papers were combined and into three groups (1-2, 3-5, and 6 ≤ authors). The analysis focused on whether the work was done by members of one institution, or in collaboration with other units of the same institution, or in collaboration with other national or multinational institutes. In the past 10 years, the EJPS published 996 articles (616 ORs/OAs, 380 CRs/CGs). The one and two authored publications (125) have not decreased, the three to five authored articles (552) changed minimally, whereas the number of 6 ≤ authored publications (319) has increased. Of 996 publications, 348 were from single institutes and 648 were written in collaboration with two or more other institutes. In addition, in this 10-year period, the number of multinational articles has increased significantly from 24 to 59. Increase in cooperation within and between institutions is a positive trend, aiming with the goal of improving quality of publications. Georg Thieme Verlag KG Stuttgart · New York.

In his 1960 paper Man-Machine Symbiosis, Licklider predicted that human brains and computing machines will be coupled in a tight partnership that will think as no human brain has ever thought and process data in a way not approached by the information-handling machines we know today. Today we are on the threshold of resurrecting the vision of symbiosis. While Licklider’s original vision suggested a co-equal relationship, here we discuss an updated vision, neo-symbiosis, in which the human holds a superordinate position in an intelligent human-computer collaborative environment.

To analyze factors associated with progression of an original scientific presentation at the American Society of Pediatric Otolaryngology (ASPO) Annual Meeting to publication in a peer-reviewed journal. A dataset of presenters was created to enable prospective follow-up to assess early impressions regarding publication success with longer-term publication outcomes. Prior to the Annual ASPO meeting in 2013, a survey consisting of 10 questions was e-mailed to all 59 presenters. Questions were designed to assess presenter expectations on publication, barriers to publishing, and experience in presenting, publishing and clinical practice. A second survey was sent 12 months later to those respondents of the first survey who were amenable to follow-up. Overall, 46 of 59 (78%) presenters responded to the initial survey prior to their ASPO 2013 presentation. Of these, 34 agreed to participate in a longer-term follow-up of their presentation to publication experience. Of these 34, there were 17 who participated in the follow-up survey 1 year later. Just under half of the original respondents were residents (46%). All presenters (100%) planned to re-submit a revised manuscript if initially rejected. However, 35% of follow-up respondents did not make initial submission to a peer-reviewed journal. Results of a descriptive analysis suggest that more experienced researchers expect their submitted manuscript to be accepted for publication within a shorter time frame than those that have published fewer papers. Time was ranked as the greatest barrier to publication (60%) of those surveyed both in the initial prospective survey and for those who did not publish a paper in the follow-up survey (83%). This study suggests a strong desire and expectation of publishing ASPO presentations. Despite this expectation, past research and this data set suggest this expectation often does not materialize. "Time constraints" were the most commonly identified barrier to publication. To enhance dissemination of new findings from ASPO meetings, institutions and individuals should examine methods that facilitate and incentivize publication of findings in peer-reviewed publications.

The production and recognition of psychiatric original articles published in languages other than English.

PubMed

Baethge, Christopher

2013-03-26

Whereas the most influential journals in psychiatry are English language journals, periodicals published in other languages serve an important purpose for local communities of clinicians and researchers. This study aimed at analyzing the scientific production and the recognition of non-English general psychiatry journals. In a cohort study, the 2009 volume of ten journals from Brazil (1), German language countries (5), France (2), Italy (1), and Poland (1) was searched for original articles. Patterns of citations to these articles during 2010 and 2011 as documented in Web of Science were analyzed. The journals published 199 original articles (range: 4-46), mostly observational studies. Half of the papers were cited in the following two years. There were 246 citations received, or an average of 1.25 cites per article (range: 0.25-4.04). Many of these citations came from the local community, that is, from the same authors and journals. Citations by other periodicals and other authors accounted for 36% [95%-CI: 30%-42%], citations in English sources for 33% [28%-39%] of all quotations. There was considerable heterogeneity with regard to citations received among the ten journals investigated. Non-English language general psychiatry journals contribute substantially to the body of research. However, recognition, and in particular recognition by the international research community is moderate.

Despite increasing numbers of women attending medical school and completing residencies, women continue to lag behind men in academic achievement. Other specialties have found that women publish fewer journal articles than men. While family medicine is becoming increasingly gender balanced, the aim of this study was to evaluate the gender balance of published material within family medicine journals. All original articles were reviewed in five family medicine journals published in the United States (Family Medicine, Journal of Family Practice, Journal of the American Board of Family Medicine, Annals of Family Medicine, and American Family Physician) between 2006-2008. The articles were categorized based on type of publication and gender of first author. The editorial boards of each of the journals were examined to determine gender breakdown. A total of 2,126 articles were included in the study. Females were first author on 712 (33.5%) of the articles, and males authored 1,414 (66.5%). There was no significant difference between years. More female authors wrote original research, and fewer wrote letters to the editor. Only Family Medicine had gender parity on its editorial board. Female authors wrote about a third of all original publications in family medicine journals between 2006-2009 even though they comprise 44% of the faculty. Further research can evaluate reasons for this gender disparity.

The Response Evaluation Criteria in Solid Tumours (RECIST) were developed and published in 2000, based on the original World Health Organisation guidelines first published in 1981. In 2009, revisions were made (RECIST 1.1) incorporating major changes, including a reduction in the number of lesions to be assessed, a new measurement method to classify lymph nodes as pathologic or normal, the clarification of the requirement to confirm a complete response or partial response and new methodologies for more appropriate measurement of disease progression. The purpose of this paper was to summarise the questions posed and the clarifications provided as an update to the 2009 publication. Copyright © 2016. Published by Elsevier Ltd.

Effects of gamma irradiation on deteriorated paper

Bicchieri, Marina; Monti, Michela; Piantanida, Giovanna; Sodo, Armida

Even though gamma radiation application, also at the minimum dosage required for disinfection, causes depolymerization and degradation of the paper substrate, recently published papers seemed, instead, to suggest that γ-rays application could be envisaged in some conditions for Cultural Heritage original documents and books. In some of the published papers, the possible application of γ-rays was evaluated mainly by using mechanical tests that scarcely reflect the chemical modifications induced in the cellulosic support. In the present article the effect of low dosage γ-irradiation on cellulosic substrates was studied and monitored applying different techniques: colorimetry, spectroscopic measurements, carbonyl content and average viscometric degree of polymerization. Two different papers were investigated, a non-sized, non-filled cotton paper, and a commercial permanent paper. To simulate a real deteriorated document, which could need γ-rays irradiation, some samples were submitted to a hydrolysis treatment. We developed a treatment based on the exposition of paper to hydrochloric acid vapors, avoiding any contact of the samples with water. This method induces a degradation similar to that observed on original documents. The samples were then irradiated with 3 kGy γ-rays at a 5258 Gy/h rate. The aforementioned analyses were performed on the samples just irradiated and after artificial ageing. All tests showed negative effects of gamma irradiation on paper. Non-irradiated paper preserves better its appearance and chemical properties both in the short term and after ageing, while the irradiated samples show appreciable color change and higher oxidation extent. Since the Istituto centrale restauro e conservazione patrimonio archivistico e librario is responsible for the choice of all restoration treatments that could be applied on library and archival materials under the protection of the Italian State (http://www.icpal.beniculturali.it/allegati/DM-7-10-2008-Istituto.pdf), it has been evaluated that the modifications induced by γ-rays irradiation are not acceptable as safe conservation treatment (http://www.icpal.beniculturali.it/allegati/Nota_uso_raggi_gamma.pdf).

Examining the Reproducibility of 6 Published Studies in Public Health Services and Systems Research.

Research replication, or repeating a study de novo, is the scientific standard for building evidence and identifying spurious results. While replication is ideal, it is often expensive and time consuming. Reproducibility, or reanalysis of data to verify published findings, is one proposed minimum alternative standard. While a lack of research reproducibility has been identified as a serious and prevalent problem in biomedical research and a few other fields, little work has been done to examine the reproducibility of public health research. We examined reproducibility in 6 studies from the public health services and systems research subfield of public health research. Following the methods described in each of the 6 papers, we computed the descriptive and inferential statistics for each study. We compared our results with the original study results and examined the percentage differences in descriptive statistics and differences in effect size, significance, and precision of inferential statistics. All project work was completed in 2017. We found consistency between original and reproduced results for each paper in at least 1 of the 4 areas examined. However, we also found some inconsistency. We identified incorrect transcription of results and omitting detail about data management and analyses as the primary contributors to the inconsistencies. Increasing reproducibility, or reanalysis of data to verify published results, can improve the quality of science. Researchers, journals, employers, and funders can all play a role in improving the reproducibility of science through several strategies including publishing data and statistical code, using guidelines to write clear and complete methods sections, conducting reproducibility reviews, and incentivizing reproducible science.

The top-cited articles in medical education: a bibliometric analysis.

PubMed

Azer, Samy A

2015-08-01

To identify and examine the characteristics of the 50 top-cited articles in medical education. Two searches were conducted in the Web of Knowledge database in March 2014: a search of medical education journals in the category "Education, Scientific Discipline" (List A) and a keyword search across all journals (List B). Articles identified were reviewed for citation count, country of origin, article type, journal, authors, and publication year. Both lists included 56 articles, not 50, because articles with the same absolute number of citations shared the same rank. The majority of List A articles were published in Academic Medicine (34; 60.7%) and Medical Education (16; 28.6%). In List B, 27 articles (48.2%) were published in medical education journals, 19 (33.9%) in general medicine and surgery journals, and 10 (17.9%) in higher education and educational psychology journals. Twenty-six articles were included in both lists, with different rankings. Reviews and articles constituted the majority of articles; there were only 8 research papers in List A and 13 in List B. Articles mainly originated from the United States, Canada, the Netherlands, and the United Kingdom. The majority were published from 1979 to 2007. There was no correlation between year and citation count. The finding that over half of List B articles were published in nonmedical education journals is consistent with medical education's integrated nature and subspecialty breadth. Twenty of these articles were among their respective non-medical-education journals' 50 top-cited papers, showing that medical education articles can compete with subject-based articles.

The Archives also constitute, since their origin, one of the preferential organs of expression for the Strasbourgian morphological works. All fields of morphology are represented. All zoological groups are concerned, some Invertebrates, but principally Vertebrates: Fishes, Amphibia, Reptiles, Birds, and Mammals amongst which the human species occupies a priviliged place. A total of 938 papers has been published in the Archives. Most papers are in French (833 i.e. 89.0%). Papers in English (89 i.e. 9.5%) are more numerous in the most recent volumes; other papers are in Italian (11 i.e. 1.0%) and in German (5 i.e. 0.5%).

Republication of: Contributions to the theory of gravitational radiation fields. Exact solutions of the field equations of the general theory of relativity V

Kundt, Wolfgang; Trümper, Manfred

2016-04-01

This is an English translation of a paper by Wolfgang Kundt and Manfred Trümper, first published in 1962 in the proceedings of the Academy of Sciences and Literature in Mainz (Germany). The original paper was the last of a five-part series of articles containing the first summary of knowledge about exact solutions of Einstein's equations found until then. (All the other parts of the series have already been re-published as Golden Oldies.) This fifth contribution summarizes key points of the earlier papers and applies them, in particular results from papers II and IV in the series, in the context of the propagation of gravitational radiation when matter is present. The paper has been selected by the Editors of General Relativity and Gravitation for re-publication in the Golden Oldies series of the journal. This republication is accompanied by an editorial note written by Malcolm A.H. MacCallum and by a brief autobiography of Manfred Trümper.

Lessons from a doctoral thesis.

The production of a doctoral thesis is a time-consuming affair that until recently was done in conjunction with professional publishing services. Advances in computer technology have made many sophisticated desktop publishing techniques available to the microcomputer user. We describe the computer method used, the problems encountered, and the solutions improvised in the production of a doctoral thesis by computer. The Apple Macintosh was selected for its ease of use and intrinsic graphics capabilities. A scanner was used to incorporate text from published papers into a word processing program. The body of the text was updated and supplemented with new sections. Scanned graphics from the published papers were less suitable for publication, and the original data were replotted and modified with a graphics-drawing program. Graphics were imported and incorporated in the text. Final hard copy was produced by a laser printer and bound with both conventional and rapid new binding techniques. Microcomputer-based desktop processing methods provide a rapid and cost-effective means of communicating the written word. We anticipate that this evolving technology will have increased use by physicians in both the private and academic sectors.

Creationism and intelligent design are incompatible with scientific progress: A response to Shanta and Vêdanta

Caetano-Anollés, Gustavo

2016-01-01

ABSTRACT In a recent opinion paper, B.K. Shanta claims science leaves no room for the subjective aspect of consciousness, and in doing so, attacks both origin of life and evolutionary research. He claims Vêdanta, one of the 6 orthodox schools of Hindu philosophy, offers an explanation: “the origin of everything material and nonmaterial is sentient and absolute.” Here I discuss how the pseudoscience of these creationist views, which are aligned with Intelligent Design, are incompatible with scientific progress and should not be published in scientific journals.

2010-06-01

This review of original reports on metabolic and infectious diseases that were recently published in Brazilian journals is designed to inform the readership of CLINICS about their content. I conducted a search in PubMed for original research articles (clinical or basic research) recently published (2008-2009) by Brazilian medical and biological periodicals. Papers on metabolic pathologies were retrieved by searching for appropriate keywords such as metabolic syndrome and obesity. Papers on infectious disease were obtained by entering 15 different keywords for the most commonly occurring pathologies. Review articles, editorials, letters to the editor, and case reports were manually excluded. Selected titles were then categorized into appropriate sub-categories. This search produced a total of 123 articles, which filtered down to 72 articles after eliminating editorials, review articles, letters to the Editor and case reports. Reviewed periodicals were Arquivos Brasileiros de Cardiologia, Arquivos Brasileiros de Endocrinologia e Metabologia, Brazilian Journal of Biological and Medical Research, Brazilian Journal of Infectious Diseases, Jornal de Pediatria, Jornal de Pneumologia, Revista da Associação Médica Brasileira, Revista da Escola de Enfermagem da Universidade de São Paulo, and São Paulo Medical Journal. The articles were then briefly summarized.

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

Chromatic confocal microscope using hybrid aspheric diffractive lenses

NASA Astrophysics Data System (ADS)

Rayer, Mathieu; Mansfield, Daniel

2014-05-01

A chromatic confocal microscope is a single point non-contact distance measurement sensor. For three decades the vast majority of the chromatic confocal microscope use refractive-based lenses to code the measurement axis chromatically. However, such an approach is limiting the range of applications. In this paper the performance of refractive, diffractive and Hybrid aspheric diffractive are compared. Hybrid aspheric diffractive lenses combine the low geometric aberration of a diffractive lens with the high optical power of an aspheric lens. Hybrid aspheric diffractive lenses can reduce the number of elements in an imaging system significantly or create large hyper- chromatic lenses for sensing applications. In addition, diffractive lenses can improve the resolution and the dynamic range of a chromatic confocal microscope. However, to be suitable for commercial applications, the diffractive optical power must be significant. Therefore, manufacturing such lenses is a challenge. We show in this paper how a theoretical manufacturing model can demonstrate that the hybrid aspheric diffractive configuration with the best performances is achieved by step diffractive surface. The high optical quality of step diffractive surface is then demonstrated experimentally.

To recognize the characteristics and path taken by the through analysis of the scientific production it has published over the period from 1967 to 2005. Scientometric methods were used to analyze reference data on the articles published in the Revista, retrieved from the databases ISI/Thomson Scientific (Web of Science), National Library of Medicine (PubMed) and Scientific Electronic Library Online (SciELO). The Revista is the only Brazilian publication in the field of public health that is indexed by ISI/Thomson Scientific. It is prominent as a medium for publishing Brazilian scientific production in public health and is displaying a geometric increase in publication and citation, with annual rates of 4.4% and 12.7%, respectively. The mean number of authors per paper has risen from 2 to 3.5 over recent years. Although original research articles predominate, the numbers of reviews, multicenter studies, clinical trials and validation studies have been increasing. The number of articles published in foreign languages has also increased, accounting for 13% of the total, and the leading countries originating these are the UK, USA, Argentina and Mexico. The number and diversity of journals citing the Journal has been increasing, many of which are non-Brazilian. Authorship per author shows good fit to Lotka's Law, but the parameters suggest greater concentration and less dispersion than would be expected. Among the fields of interest of published papers, the following topics account for more than 50% of the total volume: infectious-parasitic diseases and vectors; health promotion, policies and administration; and epidemiology, surveillance and disease control. The Revista shows great dynamism, without signs of abating or reaching a plateau any time soon. There are signs of progressively increasing complexity in the studies published, and more multidisciplinary work. The Revista seems to be widening its outreach and recognition, while remaining faithful to the field of public health in Brazil.

Plant proteome analysis: a 2006 update.

Jorrín, Jesús V; Maldonado, Ana M; Castillejo, Ma Angeles

2007-08-01

This 2006 'Plant Proteomics Update' is a continuation of the two previously published in 'Proteomics' by 2004 (Canovas et al., Proteomics 2004, 4, 285-298) and 2006 (Rossignol et al., Proteomics 2006, 6, 5529-5548) and it aims to bring up-to-date the contribution of proteomics to plant biology on the basis of the original research papers published throughout 2006, with references to those appearing last year. According to the published papers and topics addressed, we can conclude that, as observed for the three previous years, there has been a quantitative, but not qualitative leap in plant proteomics. The full potential of proteomics is far from being exploited in plant biology research, especially if compared to other organisms, mainly yeast and humans, and a number of challenges, mainly technological, remain to be tackled. The original papers published last year numbered nearly 100 and deal with the proteome of at least 26 plant species, with a high percentage for Arabidopsis thaliana (28) and rice (11). Scientific objectives ranged from proteomic analysis of organs/tissues/cell suspensions (57) or subcellular fractions (29), to the study of plant development (12), the effect of hormones and signalling molecules (8) and response to symbionts (4) and stresses (27). A small number of contributions have covered PTMs (8) and protein interactions (4). 2-DE (specifically IEF-SDS-PAGE) coupled to MS still constitutes the almost unique platform utilized in plant proteome analysis. The application of gel-free protein separation methods and 'second generation' proteomic techniques such as multidimensional protein identification technology (MudPIT), and those for quantitative proteomics including DIGE, isotope-coded affinity tags (ICAT), iTRAQ and stable isotope labelling by amino acids in cell culture (SILAC) still remains anecdotal. This review is divided into seven sections: Introduction, Methodology, Subcellular proteomes, Development, Responses to biotic and abiotic stresses, PTMs and Protein interactions. Section 8 summarizes the major pitfalls and challenges of plant proteomics.

Citation analysis represents one of the best currently available methods for quantifying the impact of articles. Bibliometric studies list the ''best sellers'' in a single field of interest. The purpose of the present study was to identify and analyze the most frequently cited papers in dry eye research that may be of high interest for researchers and clinicians. We reviewed the database of the Institute for Scientific Information to identify articles published from 1900 to September 2016. All dry eye articles published in 59 ophthalmology journals were identified. The top 100 articles were selected for further analysis of authorship, source journal, number of citations, citation rate, geographic origin, article type, and level of evidence. The 100 most-cited articles were published between 1983 and 2011, with most of them in the 2000s. The number of citations per article ranged from 96 to 610, and was greatest for articles published in the 2000s. Each of these articles was published in one of 15 journals. Most articles represented Level-III evidence, followed by Levels II and I. The present study focusing on dry eye research revealed that 55% of the most-cited articles came from the U.S. and 18% from Japan. Diagnostics and therapy were the areas of focus of most of the clinical articles; 13% of the most cited papers were review articles. This analysis provides researchers and clinicians with a detailed overview on the most cited dry eye papers over the past decades. Copyright © 2017 Elsevier Inc. All rights reserved.

Chordomas are rare malignant primary tumors of the spine. In the mobile spine and sacrum an en-bloc resection is associated with decreased rates of recurrence. Our objective was to identify the top cited articles in chordoma research and to further analyze characteristics of these articles. In March 2017, we used ISI Web of Science (v5.11, Thomas Reuter, Philadelphia, Pennsylvania, USA) to search for the following key word: "chordoma". Articles were searched from 1900 to 2017. Articles were ranked based on number of citations. The results were evaluated to determine articles most clinically relevant to the management of chordomas. The top 50 articles that met the search criteria were further characterized on the basis of: title, author, citation density, journal of publication, year (and decade) of publication, institution and country of origin and paper topic. A total of 1,043 articles matched the search criteria. The most influential 50 articles were cited 65 to 290 times. The articles were published between 1926 and 2012, and all articles were published in English. Thirty-three publications (66%) originated from the United States and seven (14%) from Italy. Cancer accounted for the most frequent (n=9) destination journal followed by Journal of Bone and Joint Surgery (n=4). A total of 41 institutions contributed to the top 50 articles. The most common article types were: clinical 44% (n=22), papers that combined clinical and pathology findings 18% (n=9) and basic science research 14% (n=7). The top 50 cited articles on chordomas are predominantly clinical papers, arising from the United States and most frequently published in Cancer and Journal of Bone and Joint Surgery .

To identify and analyze the 50 most-cited gastroenterology and hepatology articles originating from mainland China. We utilized the 2015 edition of Journal Citation Reports and PubMed to determine the 50 most-cited gastroenterology and hepatology articles from 75 professional journals and four leading journals in clinical medicine, which are The New England Journal of Medicine, The Lancet, The Journal of the American Medical Association, and The British Medical Journal. Then we excluded the articles written outside mainland China and collected the basic information, including the title, authors, year of publication, source journal, city, institution, number of citations, and topic of the research. The number of citations for the top 50 papers ranged from 279 to 89 (mean, 129). These articles were published between 2005 and 2012, in which 2009 was the year with the largest number of highly cited papers(13). All articles were published in 15 journals. The journal Hepatology published the largest number of articles(21), followed by Journal of Gastroenterology and Hepatology(4), Journal of Hepatology(4) and World Journal of Gastroenterology(4). The top 50 articles originated mainly from Shanghai(20), Guangzhou(13) and Beijing(6). Sun Yat-sen University produced most highly cited papers(10). The number of basic research was far more than clinical research, of which the ratio was about 1.78(32:18). In all these articles, hepatocellular carcinoma was the most-discussed topic(19), followed by hepatitis B virus(8) and endoscopic(5). Although a large gap remains between mainland China and the global community, the gastroenterology and hepatology research from China is gradually recognized by the world.

Motivation: Data compression is crucial in effective handling of genomic data. Among several recently published algorithms, ERGC seems to be surprisingly good, easily beating all of the competitors. Results: We evaluated ERGC and the previously proposed algorithms GDC and iDoComp, which are the ones used in the original paper for comparison, on a wide data set including 12 assemblies of human genome (instead of only four of them in the original paper). ERGC wins only when one of the genomes (referential or target) contains mixed-cased letters (which is the case for only the two Korean genomes). In all other cases ERGC is on average an order of magnitude worse than GDC and iDoComp.

Motivation Reproducing the results from a scientific paper can be challenging due to the absence of data and the computational tools required for their analysis. In addition, details relating to the procedures used to obtain the published results can be difficult to discern due to the use of natural language when reporting how experiments have been performed. The Investigation/Study/Assay (ISA), Nanopublications (NP), and Research Objects (RO) models are conceptual data modelling frameworks that can structure such information from scientific papers. Computational workflow platforms can also be used to reproduce analyses of data in a principled manner. We assessed the extent by which ISA, NP, and RO models, together with the Galaxy workflow system, can capture the experimental processes and reproduce the findings of a previously published paper reporting on the development of SOAPdenovo2, a de novo genome assembler. Results Executable workflows were developed using Galaxy, which reproduced results that were consistent with the published findings. A structured representation of the information in the SOAPdenovo2 paper was produced by combining the use of ISA, NP, and RO models. By structuring the information in the published paper using these data and scientific workflow modelling frameworks, it was possible to explicitly declare elements of experimental design, variables, and findings. The models served as guides in the curation of scientific information and this led to the identification of inconsistencies in the original published paper, thereby allowing its authors to publish corrections in the form of an errata. Availability SOAPdenovo2 scripts, data, and results are available through the GigaScience Database: http://dx.doi.org/10.5524/100044; the workflows are available from GigaGalaxy: http://galaxy.cbiit.cuhk.edu.hk; and the representations using the ISA, NP, and RO models are available through the SOAPdenovo2 case study website http://isa-tools.github.io/soapdenovo2/.

A review of literature published a decade ago noted a significant increase in empirical papers across nine bioethics journals. This study provides an update on the presence of empirical papers in the same nine journals. It first evaluates whether the empirical trend is continuing as noted in the previous study, and second, how it is changing, that is, what are the characteristics of the empirical works published in these nine bioethics journals. A review of the same nine journals (Bioethics; Journal of Medical Ethics; Journal of Clinical Ethics; Nursing Ethics; Cambridge Quarterly of Healthcare Ethics; Hastings Center Report; Theoretical Medicine and Bioethics; Christian Bioethics; and Kennedy Institute of Ethics Journal) was conducted for a 12-year period from 2004 to 2015. Data obtained was analysed descriptively and using a non-parametric Chi-square test. Of the total number of original papers (N = 5567) published in the nine bioethics journals, 18.1% (n = 1007) collected and analysed empirical data. Journal of Medical Ethics and Nursing Ethics led the empirical publications, accounting for 89.4% of all empirical papers. The former published significantly more quantitative papers than qualitative, whereas the latter published more qualitative papers. Our analysis reveals no significant difference (χ2 = 2.857; p = 0.091) between the proportion of empirical papers published in 2004-2009 and 2010-2015. However, the increasing empirical trend has continued in these journals with the proportion of empirical papers increasing from 14.9% in 2004 to 17.8% in 2015. This study presents the current state of affairs regarding empirical research published nine bioethics journals. In the quarter century of data that is available about the nine bioethics journals studied in two reviews, the proportion of empirical publications continues to increase, signifying a trend towards empirical research in bioethics. The growing volume is mainly attributable to two journals: Journal of Medical Ethics and Nursing Ethics. This descriptive study further maps the still developing field of empirical research in bioethics. Additional studies are needed to completely map the nature and extent of empirical research in bioethics to inform the ongoing debate about the value of empirical research for bioethics.

Teaching How to Prepare a Manuscript by Means of Rewriting Published Scientific Papers

Tomaska, Lubomir

2007-01-01

The objective of the course described here is to train undergraduate students to write a scientific manuscript. The students participate in selection of a current topic in contemporary genetics or molecular biology by choosing the most interesting paper of a given year. After the teacher provides all essential background about the selected subject, he or she selects a recent article from the corresponding field and presents the students with all the necessary information contained in the paper without revealing its title and author. The data presented in the paper are reviewed by the class so that each student understands every experiment and the main points of the work. Simultaneously, the students are informed about the basic rules of writing the individual sections of a scientific paper. They are then asked to write and formally submit a manuscript summarizing the data. Finally, the students act as reviewers of their colleagues' manuscripts and compare their papers with the original published articles. This enables them to identify both the strengths and the weaknesses of their manuscripts and to gain confidence in the writing skills that will be so critical for their future scientific activities.

This article has been removed at the request of the Editor-in-chief and Author. Please see Elsevier Policy on Article Withdrawal ( http://www.elsevier.com/locate/withdrawalpolicy). Reason: This article has been retracted at the request of the Editor-in-Chief and Author as the author has plagiarized part of a paper that had already appeared in another journal, as written by the following authors: Roy, Weeks, Rouault, Nelson, Barlow, Van der Lingen. "Extreme oceanographic events recorded in the Southern Benguela during the 1999-2000 summer season", South African J. Sci., 2001, volume 97 (11-12), pp. 465-471. While the underlying scientific data of Dr Krishna's work may be original, the wording, sentence, and paragraph structure of the entire manuscript shows such strong similarity (in many cases wholesale replication of sentences and phrases) that we must conclude that there has been excessive use of previously published material without appropriate attribution and is consequently not an original contribution. One of the conditions of submission of a paper for publication is that authors declare explicitly that their work is original and has not appeared in a publication elsewhere. Re-use of any data should be appropriately cited. As such this article represents a severe abuse of the scientific publishing system. The scientific community takes a very strong view on this matter and we apologize to readers of the journal that this was not detected during the submission process.

Background Statistical analysis is essential in regard to obtaining objective reliability for medical research. However, medical researchers do not have enough statistical knowledge to properly analyze their study data. To help understand and potentially alleviate this problem, we have analyzed the statistical methods and errors of articles published in the Korean Journal of Pain (KJP), with the intention to improve the statistical quality of the journal. Methods All the articles, except case reports and editorials, published from 2004 to 2008 in the KJP were reviewed. The types of applied statistical methods and errors in the articles were evaluated. Results One hundred and thirty-nine original articles were reviewed. Inferential statistics and descriptive statistics were used in 119 papers and 20 papers, respectively. Only 20.9% of the papers were free from statistical errors. The most commonly adopted statistical method was the t-test (21.0%) followed by the chi-square test (15.9%). Errors of omission were encountered 101 times in 70 papers. Among the errors of omission, "no statistics used even though statistical methods were required" was the most common (40.6%). The errors of commission were encountered 165 times in 86 papers, among which "parametric inference for nonparametric data" was the most common (33.9%). Conclusions We found various types of statistical errors in the articles published in the KJP. This suggests that meticulous attention should be given not only in the applying statistical procedures but also in the reviewing process to improve the value of the article. PMID:20552071

Jerzy Morawiecki (1910-1997) was a man with versatile interests. Being an assistant of Professor Władysław Szumowski in the Jagiellonian University he published papers devoted to the history of medicine. After getting his medical degree in 1937 he worked in the Public Health Department in Warsaw under the very well known Ludwik Hirszfeld. There he carried out pioneer studies on the blood groups, the very beginning of a new science - immunology which moulded the scientific interests to which he was faithful for the rest of his life. Under the Nazi occupation of Warsaw he managed to send his paper on blood groups to Switzerland where it was published in 1941. Between 1946 and 1992 he published 18 papers in the field of immunology mainly of the eye. He did pioneer work on the precipitation of antigens and antibodies. The phenomenon of precipitation lines in the cornea is quoted in the literature as the "Morawiecki phenomenon" or as "Morawiecki' lines". He presented the original hypothesis of immunotherapy of intravitreal hemorrhages - the method of acceleration of hemorrhage absorption. The use of Anti-RhD antibodies subsequently became the most effective method of intraocular hemorrhages.

Last year, the centenary of the 1916 Easter rising in Ireland was marked by a commemorative programme organised by the Irish government including both historical and cultural events. The main themes of these events were remembering the past, celebrating Irish achievements and imagining our future. Reviewing the medical literature offers an insight into a century of achievement and change in Irish medicine, captured from the unique perspective of Ireland's oldest medical journal. This manuscript examines papers published during the last 100 years of the Irish Journal of Medical Science, specifically examining the most cited paper from each year. The majority of top cited papers originate in Ireland (77%) with Trinity College Dublin the commonest institution (n = 12) and obstetrics the most common specialty (n = 9). The average number of citations per article was 20.56 (SD ± 22.36; range 1-118) and the article with most citations was 'Coagulative properties of cancers' published in 1958 by O'Meara et al. The mean number of citations for the top cited publication each year has increased over time. The journal continued to publish even amidst backgrounds of war and civil unrest and represents an important cultural artefact that deserves our ongoing support.

The purpose of this study was to identify the characteristics associated with highly cited papers in orthognathic surgery. This was a cohort study of articles published in the English-language literature from 1900 to 2017. Citation databases were searched for papers related to orthognathic surgery and the most frequently cited papers were identified. For each paper, the following variables were collected: region of origin, time-period of publication, corresponding author specialty, journal of publication, topic area, study design, and number of citations. The outcome variable was the citation index (citations per year). North American investigators published 70% of the 100 most-cited articles in orthognathic surgery. The majority of papers were from oral and maxillofacial surgeons. Frequent content areas were diagnosis, virtual planning, fixation/stability, and complications. The majority (54%) of studies were cohort or case report/series. The mean number of citations was 235.0±126.5; the mean citation index was 9.9±6.1 citations per year. Time-period, content area, and study design were associated with the citation index (all P<0.001). Time-period, content area, and study design predicted the citation index (all P≤0.009). Among frequently cited papers in orthognathic surgery, oral and maxillofacial surgeons had the highest volume of contributions. Diagnosis, treatment planning, and complications were the most common topics studied. Copyright © 2018 International Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd.

Bibliometric review of the literature. To analyze and quantify the most frequently cited papers in lumbar spine surgery and to measure their impact on the entire lumbar spine literature. Lumbar spine surgery is a dynamic and complex field. Basic science and clinical research remain paramount in understanding and advancing the field. While new literature is published at increasing rates, few studies make long-lasting impacts. The Thomson Reuters Web of Knowledge was searched for citations of all papers relevant to lumbar spine surgery. The number of citations, authorship, year of publication, journal of publication, country of publication, and institution were recorded for each paper. The most cited paper was found to be the classic paper from 1990 by Boden et al that described magnetic resonance imaging findings in individuals without back pain, sciatica, and neurogenic claudication showing that spinal stenosis and herniated discs can be incidentally found when scanning patients. The second most cited study similarly showed that asymptomatic patients who underwent lumbar spine magnetic resonance imaging frequently had lumbar pathology. The third most cited paper was the 2000 publication of Fairbank and Pynsent reviewing the Oswestry Disability Index, the outcome-measure questionnaire most commonly used to evaluate low back pain. The majority of the papers originate in the United States (n=58), and most were published in Spine (n=63). Most papers were published in the 1990s (n=49), and the 3 most common topics were low back pain, biomechanics, and disc degeneration. This report identifies the top 100 papers in lumbar spine surgery and acknowledges those individuals who have contributed the most to the advancement of the study of the lumbar spine and the body of knowledge used to guide evidence-based clinical decision making in lumbar spine surgery today. 3.

The status of citations can reflect the impact of a paper and its contribution to surgical practice. The aim of our study was to identify and review the 100 most-cited papers in general thoracic surgery. Relevant papers on general thoracic surgery were searched through Thomson Reuters Web of Science in the last week of November 2017. Results were returned in descending order of total citations. Their titles and abstracts were reviewed to identify whether they met our inclusion criteria by two thoracic surgeons independently. Characteristics of the first 100 papers, including title, journal name, country, first author, year of publication, total citations, citations in latest 5 years and average citation per year (ACY) were extracted and analyzed. Of the 100 papers, the mean number of citations was 322 with a range from 184 to 921. 19 journals published the papers from 1956 to 2012. Annals of Surgery had the largest number (29), followed by Journal of Thoracic and Cardiovascular Surgery (22) and Annals of Thoracic Surgery (21). The majority of the papers were published in 2000s (48) and originated from United States of America (62). There were 65 retrospective studies, 13 RCTs and 11 prospective studies. Orringer MB and Grillo HC contributed 4 first-author articles respectively. There were 53 papers on esophagus, 36 on lung, 6 on pleura and 5 on trachea. Our study identified the most-cited papers in the past several decades and offered insights into the development and advances of general thoracic surgery. It can help us understand the evidential basis of clinical decision-making today in the area. Copyright © 2018. Published by Elsevier Ltd.

The production and recognition of psychiatric original articles published in languages other than English

PubMed Central

2013-01-01

Background Whereas the most influential journals in psychiatry are English language journals, periodicals published in other languages serve an important purpose for local communities of clinicians and researchers. This study aimed at analyzing the scientific production and the recognition of non-English general psychiatry journals. Methods In a cohort study, the 2009 volume of ten journals from Brazil (1), German language countries (5), France (2), Italy (1), and Poland (1) was searched for original articles. Patterns of citations to these articles during 2010 and 2011 as documented in Web of Science were analyzed. Results The journals published 199 original articles (range: 4–46), mostly observational studies. Half of the papers were cited in the following two years. There were 246 citations received, or an average of 1.25 cites per article (range: 0.25-4.04). Many of these citations came from the local community, that is, from the same authors and journals. Citations by other periodicals and other authors accounted for 36% [95%-CI: 30%-42%], citations in English sources for 33% [28%-39%] of all quotations. There was considerable heterogeneity with regard to citations received among the ten journals investigated. Conclusion Non-English language general psychiatry journals contribute substantially to the body of research. However, recognition, and in particular recognition by the international research community is moderate. PMID:23531084

Steen, M

2001-06-30

The decline in incidence of tuberculosis in Scandinavia has stagnated in the last decades because of a growing number of immigrants from high incidence countries. The aim of this study was to find out what has been published on tuberculosis among immigrants in Denmark, Norway and Sweden in the main medical journals in these countries from 1995 to 2000. 23 papers on the topic were identified through PubMed searches. Eight papers were selected for a more detailed description of their content. The main medical journals in Denmark, Norway and Sweden have published papers on epidemiological aspects and clinical traits as well as the challenge for the health services of controlling tuberculosis in immigrants. The majority of patients are under the age of 40 and of African origin. They seldom infect the population of the host country. Extrapulmonary tuberculosis is relatively common. Control on arrival could be improved in all three countries. Considerable doctor's and patient's delay is not uncommon. Medical journals are an important source for knowledge on tuberculosis among immigrants from high incidence countries.

From Kratzenstein to Wheatstone: Episodes in the early history of free reed acoustics

NASA Astrophysics Data System (ADS)

Cottingham, James P.

2002-05-01

In 1780 C. G. Kratzenstein published a paper in St. Petersburg describing a machine which produced vowel sounds using free reeds with resonators of various shapes. This marks a convenient, if arbitrary, starting point for the history of the free reed musical instruments of European origin. These instruments developed rapidly, and by 1850 the accordion, concertina, harmonica, reed organ, and harmonium all had been invented and developed into more or less final form. A key figure in this period is Charles Wheatstone, who not only published papers on acoustical research but was also an inventor and commercially successful manufacturer of musical instruments, most notably the Wheatstone English concertina. Much of Wheatstone's research in acoustics and almost all of his work as an inventor of musical instruments involved free reeds. This paper presents some episodes in the development of the free reed instruments and some examples of acoustical research involving free reeds during the 18th and 19th centuries.

Job satisfaction among hospital nurses revisited: a systematic review.

2012-08-01

The current nursing shortage and high turnover is of great concern in many countries because of its impact upon the efficiency and effectiveness of any healthcare delivery system. Recruitment and retention of nurses are persistent problems associated with job satisfaction. To update review paper published in 2005. This paper analyses 100 papers relating to job satisfaction among hospital nurses derived from systematic searches of seven databases covering English and Chinese language publications 1966-2011 (updating the original paper with 46 additional studies published 2004-2011). Despite varying levels of job satisfaction across studies, sources and effects of job satisfaction were similar. Hospital nurse job satisfaction is closely related to working conditions and the organizational environment, job stress, role conflict and ambiguity, role perception and role content, organizational and professional commitment. More research is required to understand the relative importance of the many identified factors relating to job satisfaction of hospital nurses. It is argued that the absence of a robust causal model reflecting moderators or moderator is undermining the development of interventions to improve nurse retention. Copyright © 2011 Elsevier Ltd.

The experience of critiquing published research: learning from the student and researcher perspective.

PubMed

Knowles, Judie M; Gray, Morag A

2011-11-01

This paper commences with affirmation of the importance of research critique within academic programmes of study, and the context of this skill within the nursing profession. Judie (student) shares an experience from a Professional Doctorate in Education (EdD) assignment that involved selecting and critiquing a piece of published research. "The qualities of an effective mentor" (Gray and Smith, 2000) was critiqued using the Critical Appraisal Skills Programme (CASP, 2006) framework. Morag was the researcher and co-author (Gray and Smith, 2000) and was subsequently contacted by Judie for the purposes of validating her critique assignment. On the tenth anniversary since publication of her PhD research findings Morag reflects on the original article in the light of Judie's critique and shares evaluative comments. Some of the assignment critique is validated by Morag, whilst some of the evaluation demonstrates unreliability of critique shown by Judie. Discussion surrounding sufficiency of research critique through systematic examination of a published article, versus an original research report such as a thesis ensues. The student and researcher/author reveal their learning from this collaborative experience and conclude with recommendations for; setting critique assignments; authors publishing their research findings; and students undertaking critique assignments.

Electronic health (eHealth) and mobile health (mHealth) approaches to address low physical activity levels, sedentary behavior, and unhealthy diets have received significant research attention. However, attempts to systematically map the entirety of the research field are lacking. This gap can be filled with a bibliometric study, where publication-specific data such as citations, journals, authors, and keywords are used to provide a systematic overview of a specific field. Such analyses will help researchers better position their work. The objective of this review was to use bibliometric data to provide an overview of the eHealth and mHealth research field related to physical activity, sedentary behavior, and diet. The Web of Science (WoS) Core Collection was searched to retrieve all existing and highly cited (as defined by WoS) physical activity, sedentary behavior, and diet related eHealth and mHealth research papers published in English between January 1, 2000 and December 31, 2016. Retrieved titles were screened for eligibility, using the abstract and full-text where needed. We described publication trends over time, which included journals, authors, and countries of eligible papers, as well as their keywords and subject categories. Citations of eligible papers were compared with those expected based on published data. Additionally, we described highly-cited papers of the field (ie, top ranked 1%). The search identified 4805 hits, of which 1712 (including 42 highly-cited papers) were included in the analyses. Publication output increased on an average of 26% per year since 2000, with 49.00% (839/1712) of papers being published between 2014 and 2016. Overall and throughout the years, eHealth and mHealth papers related to physical activity, sedentary behavior, and diet received more citations than expected compared with papers in the same WoS subject categories. The Journal of Medical Internet Research published most papers in the field (9.58%, 164/1712). Most papers originated from high-income countries (96.90%, 1659/1717), in particular the United States (48.83%, 836/1712). Most papers were trials and studied physical activity. Beginning in 2013, research on Generation 2 technologies (eg, smartphones, wearables) sharply increased, while research on Generation 1 (eg, text messages) technologies increased at a reduced pace. Reviews accounted for 20 of the 42 highly-cited papers (n=19 systematic reviews). Social media, smartphone apps, and wearable activity trackers used to encourage physical activity, less sedentary behavior, and/or healthy eating were the focus of 14 highly-cited papers. This study highlighted the rapid growth of the eHealth and mHealth physical activity, sedentary behavior, and diet research field, emphasized the sizeable contribution of research from high-income countries, and pointed to the increased research interest in Generation 2 technologies. It is expected that the field will grow and diversify further and that reviews and research on most recent technologies will continue to strongly impact the field. ©Andre Matthias Müller, Carol A Maher, Corneel Vandelanotte, Melanie Hingle, Anouk Middelweerd, Michael L Lopez, Ann DeSmet, Camille E Short, Nicole Nathan, Melinda J Hutchesson, Louise Poppe, Catherine B Woods, Susan L Williams, Petra A Wark.

High-energy physicists worldwide rely on online resources such as SPIRES and arXiv to perform gather research and share their own publications. SPIRES is a tool designed to search the literature within high-energy physics, while arXiv provides the actual full-text documents of this literature. In high-energy physics, papers are often ranked according to the number of citations they acquire - meaning the number of times a later paper references the original. This paper investigates the correlation between the number of times a paper is clicked in order to be downloaded and the number of citations it receives following the click.

The published articles of the Chinese Journal of Parasitology and Parasitic Diseases in 2009-2012 (including original articles, experimental researches, field researches and clinical researches) were statistically analyzed. Together 258 research papers were published in the 4 years, and funded papers occupied 82.2% (212/258). The number of papers funded by 1, 2, 3, 4, and 5 foundations projects was 116, 58, 29, 7 and 2, respectively. 61.8% (131/212) of the foundations projects were at the national level; 28.3% (60/212) were at provincial and ministerial level. The papers supported by academy and international agencies accounted for 7.1% (15/212), 2.8% (6/212), respectively. The funded thesis mainly referred to schistosomiasis (35, 16.5%), cystic echinococcosis (29, 13.7%), malaria (24, 11.3%), toxoplasmosis (22, 10.4%), and cysticercosis (9, 4.2%). Five fields covered in these papers were as follows: epidemiology (29, 13.7%), immunology and diagnosis (53, 25%), molecular biology (75, 35.4%), etiology (28,13.2%), and pharmacology (24, 11.3%). The ratio of founded paper was 0.70, 0.67, 0.74, and 0.65 during 2009-2012, respectively. The high ratio of founded paper indicated that this journal is with domestic and abroad importance in the field of parasitology.

As duplicate publication is unethical, our aim was to find out how common it is among published papers on oral and maxillofacial surgery. We used PubMed to identify index articles published in 2010 in the Journal of Oral and Maxillofacial Surgery, the British Journal of Oral and Maxillofacial Surgery, and the European Journal of Cranio-Maxillo-Facial Surgery, and searched for possible duplicate publications from 2008 to 2012 using the first or second and last authors' names. Suspected duplicates were categorised into "non-duplicate" (no overlap), "duplicate" (identical results and conclusions), or "salami-sliced" publications (part of the index article repeated or continued). Of the 589 index articles, 17 (3%) had some form of duplication, but specifically, we found 3 duplicate, and 15 salami-sliced publications. Most redundant articles originated from China (n=4), followed by Italy, Japan, and Germany (3 from each) and the United States and Denmark (2 each). Of the 18 redundant publications, 9 did not reference the related index article. Duplicate material is still being published, and salami-slicing is relatively common among publications on oral and maxillofacial surgery. Further research is required into the extent and impact of this finding. Copyright © 2015 The British Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd. All rights reserved.

Glioma is the most common intracranial tumor and has a poor patient prognosis. The presence of brain tumor stem cells was gradually being understood and recognized, which might be beneficial for the treatment of glioma. To use bibliometric indexes to track study focuses on glioma stem cell, and to investigate the relationships among geographic origin, impact factors, and highly cited articles indexed in Web of Science. A list of citation classics for glioma stem cells was generated by searching the database of Web of Science-Expanded using the terms "glioma stem cell" or "glioma, stem cell" or "brain tumor stem cell". The top 63 cited research articles which were cited more than 100 times were retrieved by reading the abstract or full text if needed. Each eligible article was reviewed for basic information on subject categories, country of origin, journals, authors, and source of journals. Inclusive criteria: (1) articles in the field of glioma stem cells which was cited more than 100 times; (2) fundamental research on humans or animals, clinical trials and case reports; (3) research article; (4) year of publication: 1899-2012; and (5) citation database: Science Citation Index-Expanded. Exclusive criteria: (1) articles needing to be manually searched or accessed only by telephone; (2) unpublished articles; and (3) reviews, conference proceedings, as well as corrected papers. Of 2 040 articles published, the 63 top-cited articles were published between 1992 and 2010. The number of citations ranged from 100 to 1 754, with a mean of 280 citations per article. These citation classics came from nineteen countries, of which 46 articles came from the United States. Duke University and University of California, San Francisco led the list of classics with seven papers each. The 63 top-cited articles were published in 28 journals, predominantly Cancer Research and Cancer Cell, followed by Cell Stem Cell and Nature. Our bibliometric analysis provides a historical perspective on the progress of glioma stem cell research. Articles originating from outstanding institutions of the United States and published in high-impact journals are most likely to be cited.

The General Adaptation Syndrome: Potential misapplications to resistance exercise.

Buckner, Samuel L; Mouser, J Grant; Dankel, Scott J; Jessee, Matthew B; Mattocks, Kevin T; Loenneke, Jeremy P

2017-11-01

Within the resistance training literature, one of the most commonly cited tenets with respect to exercise programming is the "General Adaptation Syndrome" (GAS). The GAS is cited as a central theory behind the periodization of resistance exercise. However, after examining the original stress research by Hans Selye, the applications of GAS to resistance exercise may not be appropriate. To examine the original work of Hans Selye, as well as the original papers through which the GAS was established as a central theory for periodized resistance exercise. We conducted a review of Selye's work on the GAS, as well as the foundational papers through which this concept was applied to resistance exercise. The work of Hans Selye focused on the universal physiological stress responses noted upon exposure to toxic levels of a variety of pharmacological agents and stimuli. The extrapolations that have been made to resistance exercise appear loosely based on this concept and may not be an appropriate basis for application of the GAS to resistance exercise.

2013-11-01

The ensuing paper by Professor Giovanni Neri and colleagues was originally published in 1984, American Journal of Medical Genetics 19:195–207. The original article described a new family with a condition that the authors designated as the Perlman syndrome. This disorder, while uncommon, is an important multiple congenital anomaly and dysplasia syndrome; the causative gene was recently identified. This paper is a seminal work and is graciously republished by Wiley-Blackwell in the Special Festschrift issue honoring Professor Neri. We describe a familial syndrome of renal dysplasia, Wilms tumor, hyperplasia of the endocrine pancreas, fetal gigantism, multiple congenital anomalies and mental retardation. This condition was previously described by Perlman et al. [1973, 1975] and we propose to call it the "Perlman syndrome." It appears to be transmitted as an autosomal recessive trait. The possible relationships between dysplasia, neoplasia and malformation are discussed. © 2013 Wiley Periodicals, Inc.

Unique voices in harmony: Call-and-response to address race and physics teaching

2017-09-01

In the February 2016 issue of The Physics Teacher, we announced a call for papers on race and physics teaching. The response was muted at first, but has now grown to a respectable chorale-sized volume. As the manuscripts began to come in and the review process progressed, Geraldine Cochran graciously agreed to come on board as co-editor for this remarkable collection of papers, to be published throughout the fall of 2017 in TPT. Upon reviewing the original call and the responses from the physics community, the parallels between generating this collection and the grand call-and-response tradition became compelling. What follows is a conversation constructed by the co-editors that is intended to introduce the reader to the swell of voices that responded to the original call. The authors would like to thank Pam Aycock for providing many useful contributions to this editorial.

Social mobility and the well-being of individuals.

Chan, Tak Wing

2018-03-01

Several papers published in recent years have revived interest in Sorokin's dissociative thesis: the view that intergenerational social mobility has detrimental effects on the social relationships and wellbeing of individuals. In this paper, I test the dissociative thesis using data from the British Household Panel Survey and Understanding Society. On a wide range of indicators that measure participation in civic associations, contact with parents, close personal relationships, social support, subjective wellbeing, etc. individuals who have achieved long-range upward mobility (i.e. those who move from working class origin to salariat destination) tend to fare better than those who are immobile in the working class. Those who have experienced long-range downward mobility (moving from salariat origin to working class destination) do about as well as second-generation members of the working class. Overall, there is no support for Sorokin's thesis. © London School of Economics and Political Science 2017.

An updated methodology to review developing-country vaccine manufacturer viability.

Luter, Nicholas; Kumar, Ritu; Hozumi, Dai; Lorenson, Tina; Larsen, Shannon; Gowda, Bhavya; Batson, Amie

2017-07-05

In 1997, Milstien, Batson, and Meaney published "A Systematic Method for Evaluating the Potential Viability of Local Vaccine Producers." The paper identified characteristics of successful vaccine manufacturers and developed a viability framework to evaluate their performance. This paper revisits the original study after two decades to determine the ability of the framework to predict manufacturer success. By reconstructing much of the original dataset and conducting in-depth interviews, the authors developed informed views on the continued viability of manufacturers in low- and middle-income country markets. Considering the marked changes in the market and technology landscape since 1997, the authors find the viability framework to be predictive and a useful lens through which to evaluate manufacturer success or failure. Of particular interest is how incumbent and potentially new developing-country vaccine manufacturers enter and sustain production in competitive international markets and how they integrate (or fail to integrate) new technology into the production process. Ultimately, most manufacturers will need to meet global quality standards to be viable. As governments and donors consider investments in vaccine producers, the updated viability factors will be a useful tool in evaluating the prospects of manufacturers over the mid to long term. The paper emphasizes that while up-front investments are important, other critical factors-including investments in a national regulatory authority, manufacturer independence, and ability to adapt and adopt new technology-are necessary to ensure viability.

Some of our research results are discussed here and a list the papers submitted or published in the past year is provided. Besides our original model of an outer heliosheath source for the IBEX "ribbon" we have continued to explore alternative possibilities and further our understanding of this very complex region, especially in light of the possibility raised by the IBEX results that suggest the possibility of a 1-shock model.

Constructing conceptual meaning from a popular scientific paper—the case of E = mc2

NASA Astrophysics Data System (ADS)

Kapon, Shulamit

2013-01-01

Although high school physics students solve problems using the expression E = mc2, the origin of this expression and its deep conceptual meaning are hardly ever discussed due to students’ limited prior knowledge. In 1946, a year after the atomic bombs were first dropped, Albert Einstein published a popular scientific paper explaining the equivalence between mass and energy to the general public and the implications of this principle for our daily lives. This paper describes the utilization of Einstein’s paper in a high-school physics lesson on the equivalence of mass and energy, and discusses the instructional affordances of discussing exemplary popular scientific texts in a physics lesson.

EDITORIAL: Are higher quality papers cited more often? Are higher quality papers cited more often?

NASA Astrophysics Data System (ADS)

Patterson, Michael S.; Harris, Simon

2009-09-01

Most researchers are aware of the increasing emphasis placed on citations as an indicator of quality by their colleagues, as well as by administrators and librarians. But is it true that high quality papers are cited more often? In what we believe to be the only previous publication to examine this question, West and McIlwaine (2002) selected 79 papers that had been published in the journal Addiction in 1997. These papers were rated by an assistant editor of the journal on a five-level quality scale (ranging from 'among the top 10%' to 'should not have been published') as well as a second 'blind' rater. The authors found that the number of citations to each paper from 1997 to 2000 did not correlate with the mean score of the two reviewers, the score assigned by the editors, or the score assigned by the blind referees. The peer-review system used by Physics in Medicine and Biology (PMB) facilitates a larger, prospective study with much less effort. In general, two reviewers are asked to assign each paper a score of 1 to 10 in each of three categories: originality, soundness and significance. The total scores (out of 30) are averaged and on this basis manuscripts are given a quality rating from Q1 (highest quality) to Q5. In a paper recently published in Scientometrics (Patterson and Harris 2009), we compared the number of citations to papers published in PMB in 2003, 2004 and 2005 to the mean quality rating assigned by the reviewers. In total, data were analyzed for 1095 published papers. For each year we found that there was a low but statistically robust correlation between citations and quality rating: for 2003, -0.227 (p < 0.001); for 2004, -0.238 (p < 0.001), and for 2005, -0.154 (p < 0.01). The low correlation means that it is not possible to predict the citation frequency of an individual paper with accuracy but, as a group, the highest ranked papers were cited about twice as often as the average for all published papers. We also examined the data retrospectively by dividing the papers published in each year into five citation quintiles. A paper of the highest quality (Q1) was about ten times more likely to be found in the most-cited quintile than in the least-cited. While it is reassuring to find that the best papers in PMB are, indeed, cited more often on average, we cannot discount the hypothesis that both measures might be influenced by an extrinsic factor, such as the reputation of the authors. We suggest that a study similar to ours be performed for a journal that utilizes a system of double-blind peer review.

This paper describes the development of standard and reference atmosphere models along with the history of their origin and use since the mid 19th century. The first "Standard Atmospheres" were established by international agreement in the 1920's. Later some countries, notably the United States, also developed and published "Standard Atmospheres". The term "Reference Atmospheres" is used to identify atmosphere models for specific geographical locations. Range Reference Atmosphere Models developed first during the 1960's are examples of these descriptions of the atmosphere. This paper discusses the various models, scopes, applications and limitations relative to use in aerospace industry activities.

Protecting Ideas: Ethical and Legal Considerations When a Grant's Principal Investigator Changes.

2016-08-01

Ethical issues related the responsible conduct of research involve questions concerning the rights and obligations of investigators to propose, design, implement, and publish research. When a principal investigator (PI) transfers institutions during a grant cycle, financial and recognition issues need to be addressed to preserve all parties' obligations and best interests in a mutually beneficial way. Although grants often transfer with the PI, sometimes they do not. Maintaining a grant at an institution after the PI leaves does not negate the grantee institution's obligation to recognize the PI's original ideas, contributions, and potential rights to some forms of expression and compensation. Issues include maintaining a role for the PI in determining how to take credit for, share and publish results that involve his or her original ideas. Ascribing proper credit can become a thorny issue. This paper provides a framework for addressing situations and disagreements that may occur when a new PI continues the work after the original PI transfers. Included are suggestions for proactively developing institutional mechanisms that address such issues. Considerations include how to develop solutions that comply with the responsible conduct of research, equitably resolve claims regarding reporting of results, and avoid the possibility of plagiarism.

Understanding the nineteenth century origins of disciplines: lessons for astrobiology today?

NASA Astrophysics Data System (ADS)

Brazelton, William J.; Sullivan, Woodruff T., III

2009-10-01

Astrobiology's goal of promoting interdisciplinary research is an attempt to reverse a trend that began two centuries ago with the formation of the first specialized scientific disciplines. We have examined this era of discipline formation in order to make a comparison with the situation today in astrobiology. Will astrobiology remain interdisciplinary or is it becoming yet another specialty? As a case study, we have investigated effects on the scientific literature when a specialized community is formed by analyzing the citations within papers published during 1802-1856 in Philosophical Transactions of the Royal Society (Phil. Trans.), the most important ‘generalist’ journal of its day, and Transactions of the Geological Society of London (Trans. Geol. Soc.), the first important disciplinary journal in the sciences. We find that these two journals rarely cited each other, and papers published in Trans. Geol. Soc. cited fewer interdisciplinary sources than did geology papers in Phil. Trans. After geology had become established as a successful specialized discipline, geologists returned to publishing papers in Phil. Trans., but they wrote in the new, highly specialized style developed in Trans. Geol. Soc. They had succeeded in not only creating a new scientific discipline, but also a new way of doing science with its own modes of research and communication. A similar citation analysis was applied to papers published over the period 2001-2008 in the contemporary journals Astrobiology and the International Journal of Astrobiology to test the hypothesis that astrobiologists are in the early stages of creating their own specialized community. Although still too early to reliably detect any but the largest trends, there is no evidence yet that astrobiologists are drifting into their own isolated discipline. Instead, to date they appear to remain interdisciplinary.

In 2011, Nephrology Dialysis and Transplantation (NDT) established a more restrictive selection process for manuscripts submitted to the journal, reducing the acceptance rate from 25% (2008-2009) to currently about 12-15%. To achieve this goal, we decided to score the priority of manuscripts submitted to NDT and to reject more papers at triage than in the past. This new scoring system allows a rapid decision for the authors without external review. However, the risk of such a restrictive policy may be that the journal might fail to capture important studies that are eventually published in higher-ranked journals. To look into this problem, we analysed random samples of papers (∼10%) rejected by NDT in 2012. Of the papers rejected at triage and those rejected after regular peer review, 59 and 61%, respectively, were accepted in other journals. A detailed analysis of these papers showed that only 4 out of 104 and 7 out of 93 of the triaged and rejected papers, respectively, were published in journals with an impact factor higher than that of NDT. Furthermore, for all these papers, independent assessors confirmed the evaluation made by the original reviewers. The number of citations of these papers was similar to that typically obtained by publications in the corresponding journals. Even though the analyses seem reassuring, previous observations made by leading journals warn that the risk of 'big misses', resulting from selective editorial policies, remains a real possibility. We will therefore continue to maintain a high degree of alertness and will periodically track the history of manuscripts rejected by NDT, particularly papers that are rejected at triage by our journal. © The Author 2015.

Constraints on Generality (COG): A Proposed Addition to All Empirical Papers.

PubMed

Simons, Daniel J; Shoda, Yuichi; Lindsay, D Stephen

2017-11-01

Psychological scientists draw inferences about populations based on samples-of people, situations, and stimuli-from those populations. Yet, few papers identify their target populations, and even fewer justify how or why the tested samples are representative of broader populations. A cumulative science depends on accurately characterizing the generality of findings, but current publishing standards do not require authors to constrain their inferences, leaving readers to assume the broadest possible generalizations. We propose that the discussion section of all primary research articles specify Constraints on Generality (i.e., a "COG" statement) that identify and justify target populations for the reported findings. Explicitly defining the target populations will help other researchers to sample from the same populations when conducting a direct replication, and it could encourage follow-up studies that test the boundary conditions of the original finding. Universal adoption of COG statements would change publishing incentives to favor a more cumulative science.

Boris Choubert: The forgotten fit of the circum-Atlantic continents

NASA Astrophysics Data System (ADS)

Kornprobst, Jacques

2017-01-01

Boris Choubert was a strong supporter of Wegener's continental drift theory. In 1935, he published a very accurate fit of the circum-Atlantic continents, which was based on continental edges instead of coastlines; in the same paper, he interpreted the Palaeozoic belts as the result of horizontal movements of the Precambrian blocks; so, he greatly expanded the role of continental drift through time. This original and very prophetic work was almost completely ignored by his contemporaries. Thirty years later (1965), Bullard, Everett and Smith published in turn a similar but more sophisticated fit; they did not acknowledge Choubert's initial work. Bullard's fit was met with immediate and tremendous success. The present paper analyses the reasons why Boris Choubert was frustrated of his pioneering role. This lack of recognition is related to: (1) a great evolution in the geological concepts between 1935 and 1965, and (2) a poor choice of Choubert, regarding the title of his 1935 article.

Purpose The purpose of this study is to perform a citation analysis on the most frequently cited articles in the topic of cervical spine surgery and report on the top 100 most cited publication in this topic. Methods We used the Thomson Reuters Web of Science to search citations of all articles from 1945 to 2015 relevant to cervical spine surgery and ranked them according to the number of citations. The 100 most cited articles that matched the search criteria were further analyzed by number of citations, first author, journal, year of publication, country and institution of origin. Results The top 100 cited articles in the topic of cervical spine surgery were published from 1952-2011. The number of citations ranged from 106 times for the 100th paper to 1206 times for the top paper. The decade of 1990-1999 saw the most publications. The Journal of Spine published the most articles, followed by Journal of Bone and Joint Surgery America. Investigators from America authored the most papers and The University of California contributed the most publications. Cervical spine fusion was the most common topic published with 36 papers, followed by surgical technique and trauma. Conclusion This article identifies the 100 most cited articles in cervical spine surgery. It has provided insight to the history and development in cervical spine surgery and many of which have shaped the way we practice today. PMID:28765803

Revised simulation model does not predict rebound in gonorrhoea prevalence where core groups are treated in the presence of antimicrobial resistance.

To determine the effects of using discrete versus continuous quantities of people in a compartmental model examining the contribution of antimicrobial resistance (AMR) to rebound in the prevalence of gonorrhoea. A previously published transmission model was reconfigured to represent the occurrence of gonorrhoea in discrete persons, rather than allowing fractions of infected individuals during simulations. In the revised model, prevalence only rebounded under scenarios reproduced from the original paper when AMR occurrence was increased by 10(5) times. In such situations, treatment of high-risk individuals yielded outcomes very similar to those resulting from treatment of low-risk and intermediate-risk individuals. Otherwise, in contrast with the original model, prevalence was the lowest when the high-risk group was treated, supporting the current policy of targeting treatment to high-risk groups. Simulation models can be highly sensitive to structural features. Small differences in structure and parameters can substantially influence predicted outcomes and policy prescriptions, and must be carefully considered. Published by the BMJ Publishing Group Limited.

This paper reviews the huge promotion of Chairman Mao Zedong's two poems entitled "Farewell to the God of Plague" which were published 60 years ago, and the great achievements of the national schistosomiasis control programme in China. The publication of the two poems promotes the establishment of the mechanism for the national schistosomiasis control programme in China, and in addition, the schistosomiasis control spirit of the people from Yujiang County is still the source of power for the promotion of transferring the schistosomiasis control to elimination stage in China. Now, that we commemorate the 60th anniversary of publishing Chairman Mao Zedong's two poems entitled "Farewell to the God of Plague" means we remain the true to our original aspiration to serve the people forever, which is also to promote the progress of schistosomiasis elimination in China according to the law, the scientific principle, and local conditions, so as to contribute our efforts for realizing the healthy China's dream.

A Bayesian Perspective on the Reproducibility Project: Psychology

PubMed Central

Etz, Alexander; Vandekerckhove, Joachim

2016-01-01

We revisit the results of the recent Reproducibility Project: Psychology by the Open Science Collaboration. We compute Bayes factors—a quantity that can be used to express comparative evidence for an hypothesis but also for the null hypothesis—for a large subset (N = 72) of the original papers and their corresponding replication attempts. In our computation, we take into account the likely scenario that publication bias had distorted the originally published results. Overall, 75% of studies gave qualitatively similar results in terms of the amount of evidence provided. However, the evidence was often weak (i.e., Bayes factor < 10). The majority of the studies (64%) did not provide strong evidence for either the null or the alternative hypothesis in either the original or the replication, and no replication attempts provided strong evidence in favor of the null. In all cases where the original paper provided strong evidence but the replication did not (15%), the sample size in the replication was smaller than the original. Where the replication provided strong evidence but the original did not (10%), the replication sample size was larger. We conclude that the apparent failure of the Reproducibility Project to replicate many target effects can be adequately explained by overestimation of effect sizes (or overestimation of evidence against the null hypothesis) due to small sample sizes and publication bias in the psychological literature. We further conclude that traditional sample sizes are insufficient and that a more widespread adoption of Bayesian methods is desirable. PMID:26919473

Virtual special issues: A new outreach effort from The Journal of Magnetic Resonance

NASA Astrophysics Data System (ADS)

2017-01-01

The Journal of Magnetic Resonance (JMR) prides itself in the quality of its publications. JMR has seen ground-breaking concepts appear in its pages, and literally whole sub-fields have sprung up from ideas published in its articles, equations and data. The search for original papers arising from you, the magnetic resonance expert, user, contributor and reader, was and remains the Journal's raison d'etre. This bottom-up approach seeks to give an outlet to contributions from all areas of magnetic resonance, while keeping the vibrancy, depth and ingenuity that have characterized our field and our Journal for nearly fifty years. While our ambition to be a forum for all matters concerning NMR, MRI, EPR and NQR -principles and applications, science and engineering, solids and liquids, physics and chemistry- lies at the core of our editorial spirit, it also raises a paradoxical situation. The variety of topics that magnetic resonance has given origin to and that JMR intends to cover, coupled with the multiplication of journals and the diversification in publication media formats, pose severe challenges to the scientist trying to keep abreast of the latest developments in our field. In order to deal with such challenge we are hereby launching, in partnership with Elsevier, a new effort: the Virtual Special Issue (VSI). Convinced that our papers contain excellent science that may go under-noticed in the short term, VSIs seek to highlight recent original JMR publications within the context of a relatively focused area of magnetic resonance. To do so the editorial team -working together with the magnetic resonance community at large- seeks to identify a thematic goal represented by JMR, and compile on its basis a homogeneous monograph relying on papers that have been recently published or accepted in the Journal. In order to bring these VSIs to our constituency we have designed a special workflow for these selected papers: while these publications will keep their original doi's, acceptance dates and publication pages, our Journal's website will be modified to accept them as part of a "VSI Volume" in its side banners. This should maximize the immediacy, publicity and impact of the articles selected for the VSI; their profile should be further enhanced by providing email announcements of the release of these VSIs, and by making these articles available free of charge for a 6-month period after their release.

Central granular cell odontogenic tumor: a systematic review.

PubMed

Sarode, Sachin C; Sarode, Gargi S; Vaidya, Kedar

2014-03-01

Central granular cell odontogenic tumor (CGCOT) is a rare benign odontogenic neoplasm reported with various terms and is not included in the 2005 WHO classification of odontogenic tumors. It shows a predilection for middle-aged women, usually presenting as an asymptomatic swelling of the mandibular premolar-molar region. Radiographic manifestations include unilocular or multilocular radiolucent lesion, but mixed density lesions can also occur. Histopathology shows sheets and lobules of round to polygonal cells with abundant eosinophilic, granular cytoplasm and eccentrically placed nuclei. Immunohistochemical and ultrastructural features suggest the histiocytic origin of granular cells. The neoplasm does not exhibit an aggressive biological behavior and hence enucleation or curettage ensuring complete removal remains the treatment of choice. We present a systematic review on clinical, radiological, histopathological, immunohistochemical and treatment aspect of CGCOT. Published articles were identified through a literature search using online databases (PubMed, MEDLINE, Scopus) and cross-references for papers published from the year 1950 to March 2013. From a total of 37 papers, 26 (38 cases) were extracted from the database for systematic review. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Animal models for studying homeopathy and high dilutions: conceptual critical review.

PubMed

Bonamin, Leoni Villano; Endler, Peter Christian

2010-01-01

This is a systematic review of the animal models used in studies of high dilutions. The objectives are to analyze methodological quality of papers and reported results, and to highlight key conceptual aspects of high dilution to suggest clues concerning putative mechanisms of action. Papers for inclusion were identified systematically, from the Pubmed-Medline database, using 'Homeopathy' and 'Animal' as keywords. Only original full papers in English published between January 1999 and June 2009 were included, reviews, scientific reports, thesis, older papers, papers extracted from Medline using similar keywords, papers about mixed commercial formulas and books were also considered for discussion only. 31 papers describing 33 experiments were identified for the main analysis and a total of 89 items cited. Systematic analysis of the selected papers yielded evidence of some important intrinsic features of high dilution studies performed in animal models: a) methodological quality was generally adequate, some aspects could be improved; b) convergence between results and materia medica is seen in some studies, pointing toward to the possibility of systematic study of the Similia principle c) both isopathic and Similia models seem useful to understand some complex biological phenomena, such as parasite-host interactions; d) the effects of high dilutions seem to stimulate restoration of a 'stable state', as seen in several experimental models from both descriptive and mathematical points of view.

2013-03-01

Establishment of the frequency of reporting internal consistency of the scales in research published in the Colombian Journal of Psychiatry (CJP) between 2006 and 2010. A descriptive study was carried out which computes the report of internal consistency (Cronbach alpha) of scales in research published as original papers in the CJP. Validation studies were excluded. A total of 114 articles were published and 30 of them were included in the analysis. Researchers applied 67 scales for measuring some variables and Cronbach alpha of 20 (29.8%) scales was reported in the participating population. In the CJP, few published studies that apply measuring scales for variables report internal consistency in the analyzed sample. It is necessary for authors to report the internal consistency of used scales in the study population to guarantee the validity of conclusions. Copyright © 2013 Asociación Colombiana de Psiquiatría.

Interdisciplinary Laboratory Course Facilitating Knowledge Integration, Mutualistic Teaming, and Original Discovery.

2015-11-01

Experiencing the thrill of an original scientific discovery can be transformative to students unsure about becoming a scientist, yet few courses offer authentic research experiences. Increasingly, cutting-edge discoveries require an interdisciplinary approach not offered in current departmental-based courses. Here, we describe a one-semester, learning laboratory course on organismal biomechanics offered at our large research university that enables interdisciplinary teams of students from biology and engineering to grow intellectually, collaborate effectively, and make original discoveries. To attain this goal, we avoid traditional "cookbook" laboratories by training 20 students to use a dozen research stations. Teams of five students rotate to a new station each week where a professor, graduate student, and/or team member assists in the use of equipment, guides students through stages of critical thinking, encourages interdisciplinary collaboration, and moves them toward authentic discovery. Weekly discussion sections that involve the entire class offer exchange of discipline-specific knowledge, advice on experimental design, methods of collecting and analyzing data, a statistics primer, and best practices for writing and presenting scientific papers. The building of skills in concert with weekly guided inquiry facilitates original discovery via a final research project that can be presented at a national meeting or published in a scientific journal. © The Author 2015.

Lawrence, Dana J; Meeker, William C

2006-01-01

This commentary reports on the advances that have occurred over the 10-year period since the first National Workshop to Develop the Chiropractic Research Agenda was held and introduces the second set of white papers that were produced as a result of the 10th annual Research Agenda Conference. Four working groups were convened to update the original 5 white papers that represented the most significant results from the first workshop in 1996. Each group was to review the first report, examine the action steps and recommendations that were published in each report to see how much had been completed in the past decade, and develop new action steps and recommendations for the future. Four new articles were developed, each updating and adding significant amounts of new research to the original versions. New action steps and recommendations will help move the profession forward into the future. Chiropractic scientists have worked diligently over the past decade to address the recommendations noted in the first set of white papers. Despite significant advances in knowledge and scientific capacity, the chiropractic profession is still confronted with a large number of research challenges.

Genealogical Trees of Scientific Papers

PubMed Central

Waumans, Michaël Charles; Bersini, Hugues

2016-01-01

Many results have been obtained when studying scientific papers citations databases in a network perspective. Articles can be ranked according to their current in-degree and their future popularity or citation counts can even be predicted. The dynamical properties of such networks and the observation of the time evolution of their nodes started more recently. This work adopts an evolutionary perspective and proposes an original algorithm for the construction of genealogical trees of scientific papers on the basis of their citation count evolution in time. The fitness of a paper now amounts to its in-degree growing trend and a “dying” paper will suddenly see this trend declining in time. It will give birth and be taken over by some of its most prevalent citing “offspring”. Practically, this might be used to trace the successive published milestones of a research field. PMID:26954677

Scientists from less-developed countries (LDC) perceive that it is difficult to publish in international journals from their countries. This online survey was conducted with the primary aim of determining the opinion of corresponding authors of published papers in international Pharmacology journals regarding the difficulties in publications and their possible solutions. The titles of all Pharmacology journals were retrieved from Pubmed. 131 journals were included in study. The latest issue of all journals was reviewed thoroughly. An online survey was conducted from the corresponding authors of the published papers who belonged to LDC. 584 out 1919 papers (30.4%) originated from the LDC. 332 responses (response rate; 64.5%) were received from the authors. Approximately 50% the papers from LDC were published in journals with impact factor of less than 2. A weak negative correlation (r = -0.236) was observed between journal impact factor and the percentage of publications emanating from LDC. A significant majority of the corresponding authors (n = 254; 76.5%) perceived that it is difficult to publish in good quality journals from their countries. According to their opinion, biased attitude of editors and reviewers (64.8%) is the most important reason followed by the poor writing skills of the scientists from LDC (52.8%). The authors thought that well-written manuscript (76.1%), improvement in the quality of research (69.9%) and multidisciplinary research (42.9%) are important determinants that may improve the chances of publications. The LDC are underrepresented in publications in Pharmacology journals. The corresponding authors of the published articles think that biased attitude of the editors as well as the reviewers of international journals and the poor writing skills of scientists are the major factors underlying the non-acceptance of their results. They also think that the improvement in the writing skills and quality of research will increase the chances of acceptance of their works in international journals.

Neural regeneration following nerve injury is an emerging field that attracts extending interests all over the world. To use bibliometric indexes to track studies focusing on neural regeneration, and to investigate the relationships among geographic origin, countries and institutes, keywords in the published articles, and especially focus on the region distribution, institution distribution, as well as collaborations in Chinese papers indexed in the Web of Science. A list of neural regeneration studies was generated by searching the database of the Web of Science-Expanded using the term "Neural Regenera*". Inclusive criteria: (1) articles in the field of neural regeneration; (2) fundamental research on animals, clinical trials and case reports; (3) article types: article, review, proceedings paper, note, letter, editorial material, discussion, book chapter; (4) year of publication: 2003-2012; and (5) citation database: Science Citation Index-Expanded. Exclusive criteria: (1) articles requiring manual searching or with access only by telephone; (2) unpublished articles; and (3) corrections. A total of 4 893 papers were retrieved from the Web of Science published between 2003 and 2012. The papers covered 65 countries or regions, of which the United States ranked first with 1 691 papers. The most relevant papers were in the neurosciences and cell biology, and the keyword "stem cell" was the most frequent. In recent years, China showed a great increase in the number of papers. Over the entire 10 years, there were 922 Chinese papers, with Jilin University ranking first with 58 articles. Chinese papers were published in connection with many countries, including the United States, Japan, and the United Kingdom. Among the connections, the papers published by the Chinese and the American are 107, with the highest rate. With regard to funding, 689 articles were funded from various projects, occupying 74.72% of the total amount. In these projects, National Foundation and Science and Technology programs were the majority. Our bibliometric analysis provides a historical perspective on the progress of neural regeneration research. At present, the number of articles addressing neural regeneration is increasing rapidly; however, through analysis of citations it is clear that there is a long way to go to improve the academic quality.

To the best of our knowledge, there has been no systematic assessment of the classification of scientific production within the scope of radiation oncology relating to central nervous system tumors. The aim of this study was to systematically assess the status of evidence relating to the central nervous system and to evaluate the geographic origins and major content of these published data. Descriptive critical appraisal study conducted at a private hospital in São Paulo, Brazil. We evaluated all of the central nervous system studies published in the journal Radiotherapy & Oncology between 2003 and 2012. The studies identified were classified according to their methodological design and level of evidence. Information regarding the geographical location of the study, the institutions and authors involved in the publication, main condition or disease investigated and time of publication was also obtained. We identified 3,004 studies published over the 10-year period. Of these, 125 (4.2%) were considered eligible, and 66% of them were case series. Systematic reviews and randomized clinical trials accounted for approximately 10% of all the published papers. We observed an increase in high-quality evidence and a decrease in low-quality published papers over this period (P = 0.036). The inter-rater reliability demonstrated significant agreement between observers in terms of the level of evidence. Increases in high-level evidence and in the total number of central nervous system papers were clearly demonstrated, although the overall number of such studies remained relatively small.

The effect of the European Clinical Trials Directive on published drug research in anaesthesia.

Walker, E; Hankins, M C; White, S M

2009-09-01

The clinical indications for anaesthetic drugs are developed through peer-reviewed publication of clinical trials. We performed a bibliometric analysis of all human research papers reported in nine general anaesthesia journals over 6 years (n = 6489), to determine any effects of the 2004 European Clinical Trials Directive on reported drug research in anaesthesia originating from Europe and the United Kingdom. We found 89% studies involved patients and 11% volunteers. Of 3234 (50%) drug studies, 96% were phase IV (post-marketing) trials. Worldwide, the number of research papers fell by 3.6% (p < 0.004) in the 3 years following introduction of the European Clinical Trials Directive (5% Europe, 18% United Kingdom), and drug research papers fell by 12% (p < 0.001; 15% Europe, 29% United Kingdom). The introduction of the Clinical Trials Directive has therefore coincided with a decline in European drug research, particularly that originating from the United Kingdom. We suggest a number of measures researchers could take in response, and we propose a simplification of the application process for phase IV clinical trials, emphasising patient risk assessment.

Test Barcelona. Bilingüismo catalán-castellano. Adaptación lingüística de instrumentos neuropsicológicos. The present paper develops the Catalan version of the language subtests of the Barcelona Test (Peña-Casanova,1986) the original version of which was published in Spanish. To reach the Catalan version of the test it has been necessary to analyse the psycholinguistic variables of every item to then establish linguistically equivalent correlations. There are some subtests for which no modifications have been needed. Nevertheless, and because of some psycholinguistic features of Catalan (Catalan's spelling is not completely free of ambiguity) some subtests have suffered substantial modifications. The following paper presents the justification of every modification based on the features of the Catalan language and also based on the original goals of the test. An appendix contains the final version of the Catalan adaptation for the language subtests of the Barcelona Test. The present paper represents an advance in the assessment of neurological patients with language disfunctions. It will permit an appropiate assessment for the Spanish-Catalan bilingual patients.

2004-05-01

In conjunction with the upcoming release of \\it Binary Maker 3.0, an extensive on-line database of eclipsing binaries is being made available. The purposes of the atlas are: \\begin {enumerate} Allow quick and easy access to information on published eclipsing binaries. Amass a consistent database of light and radial velocity curve solutions to aid in solving new systems. Provide invaluable querying capabilities on all of the parameters of the systems so that informative research can be quickly accomplished on a multitude of published results. Aid observers in establishing new observing programs based upon stars needing new light and/or radial velocity curves. Encourage workers to submit their published results so that others may have easy access to their work. Provide a vast but easily accessible storehouse of information on eclipsing binaries to accelerate the process of understanding analysis techniques and current work in the field. \\end {enumerate} The database will eventually consist of all published eclipsing binaries with light curve solutions. The following information and data will be supplied whenever available for each binary: original light curves in all bandpasses, original radial velocity observations, light curve parameters, RA and Dec, V-magnitudes, spectral types, color indices, periods, binary type, 3D representation of the system near quadrature, plots of the original light curves and synthetic models, plots of the radial velocity observations with theoretical models, and \\it Binary Maker 3.0 data files (parameter, light curve, radial velocity). The pertinent references for each star are also given with hyperlinks directly to the papers via the NASA Abstract website for downloading, if available. In addition the Atlas has extensive searching options so that workers can specifically search for binaries with specific characteristics. The website has more than 150 systems already uploaded. The URL for the site is http://ebola.eastern.edu/.

Review and critical appraisal of studies mapping from quality of life or clinical measures to EQ-5D: an online database and application of the MAPS statement.

PubMed

Dakin, Helen; Abel, Lucy; Burns, Richéal; Yang, Yaling

2018-02-12

The Health Economics Research Centre (HERC) Database of Mapping Studies was established in 2013, based on a systematic review of studies developing mapping algorithms predicting EQ-5D. The Mapping onto Preference-based measures reporting Standards (MAPS) statement was published in 2015 to improve reporting of mapping studies. We aimed to update the systematic review and assess the extent to which recently-published studies mapping condition-specific quality of life or clinical measures to the EQ-5D follow the guidelines published in the MAPS Reporting Statement. A published systematic review was updated using the original inclusion criteria to include studies published by December 2016. We included studies reporting novel algorithms mapping from any clinical measure or patient-reported quality of life measure to either the EQ-5D-3L or EQ-5D-5L. Titles and abstracts of all identified studies and the full text of papers published in 2016 were assessed against the MAPS checklist. The systematic review identified 144 mapping studies reporting 190 algorithms mapping from 110 different source instruments to EQ-5D. Of the 17 studies published in 2016, nine (53%) had titles that followed the MAPS statement guidance, although only two (12%) had abstracts that fully addressed all MAPS items. When the full text of these papers was assessed against the complete MAPS checklist, only two studies (12%) were found to fulfil or partly fulfil all criteria. Of the 141 papers (across all years) that included abstracts, the items on the MAPS statement checklist that were fulfilled by the largest number of studies comprised having a structured abstract (95%) and describing target instruments (91%) and source instruments (88%). The number of published mapping studies continues to increase. Our updated database provides a convenient way to identify mapping studies for use in cost-utility analysis. Most recent studies do not fully address all items on the MAPS checklist.

Progress in Magnetospheric Physics: 1983-86 (Paper 7R0217)

1987-04-01

It has been a distinct pleasure, as well as an educational experience, to have served as associate editor for magnetospheric physics on this quadrennial report to IUGG. Fourteen authors and eighteen referees have done their utmost, despite the pressure of firm deadlines and the constraint of severe page limits, to make the magnetospheric report (consisting of the ten papers that follow) a valuable resource for the international space-research community. Users of this report are encouraged to cite not only the original references found pertinent to their research but also the IUGG review article(s) in which those original references were compiled. Authors of the ten review articles that follow were asked to compile fairly complete lists of relevant papers based on work performed at institutions in the United States and published between late 1982 and late 1986. Additional papers could be cited in the interest of providing context or perspective. Review authors were not required to mention in text every article included in their reference lists. The reader should attach no stigma, however, to the omission of any paper from either the text or the reference list of an IUGG review article. Any omission may have been an oversight, or it may have been necessary for the flow or balance of a particular review.

2018-06-01

Astronomy Research Seminars are offered by a rapidly growing number of community colleges and universities. Over the past decade some 120 student team research papers have been published with approximately 500 coauthors. Each team manages their own research, obtains and analyzes original data, writes a team paper, obtains an external review, submits their paper for publication, and gives a public PowerPoint presentation. The student teams are supported by: (1) an extensive community-of-practice which consists of professional and amateur astronomers, educators, and Seminar graduates; (2) the Institute for Student Astronomical Research (www.in4star.org); (3) the Small Telescope Astronomy Research Handbook and (4) an in-person/online, open-source Canvas learning management system with videos, quizzes, and other, extensive supporting material. Team research projects are completed in a semester or less and are managed by the students themselves. The Seminars have expanded from double star astronomy to asteroid astrometry, eclipsing binary times of minima, and exoplanet transits. Conducting authentic research inspires students, provides them with important skills in teamwork, project management and scientific literacy, and gives them confidence in their abilities to participate in scientific research. Being coauthors of published papers boosts student educational careers with respect to admissions and scholarships.

Objective To compare the volume and quality of original research in primary care published by researchers from primary care in the United Kingdom against five countries with well established academic primary care. Design Bibliometric analysis. Setting United Kingdom, United States, Australia, Canada, Germany, and the Netherlands. Studies reviewed Research publications relevant to comprehensive primary care and authored by researchers from primary care, recorded in Medline and Embase, with publication dates 2001-7 inclusive. Main outcome measures Volume of published activity of generalist primary care researchers and the quality of the research output by those publishing the most using citation metrics: numbers of cited papers, proportion of cited papers, and mean citation scores. Results 82 169 papers published between 2001 and 2007 in the six countries were classified as research on primary care. In a 15% pragmatic random sample of these records, 40% of research on primary care from the United Kingdom and 46% from the Netherlands was authored by researchers employed in a primary care setting or employed in academic departments of primary care. The 141 researchers with the highest volume of publications reporting research findings published between 2001 and 2007 (inclusive) authored or part authored 8.3% of the total sample of papers. For authors with the highest proportion of publications cited at least five times, the best performers came from the United States (n=5), United Kingdom (n=4), and the Netherlands (n=2). In the top 10 of authors with the highest proportions of publications achieving 20 or more citations, six were from the United Kingdom and four from the United States. The mean Hirsch index (measure of a researcher’s productivity and impact of the published work) was 14 for the Netherlands, 13 for the United Kingdom, 12 for the United States, 7 for Canada, 4 for Australia, and 3 for Germany. Conclusion This international comparison of the volume and citation rates of papers by researchers from primary care consistently placed UK researchers among the best performers internationally.

2015-04-28

To define the 100 citation classic papers of interventional radiology. Using the database of Journal Citation Reports the 40 highest impact factor radiology journals were chosen. From these journals the 100 most cited interventional radiology papers were chosen and analysed. The top paper received 2497 citations and the 100(th) paper 200 citations. The average number of citations was 320. Dates of publication ranged from 1953 - 2005. Most papers originated in the United States (n = 67) followed by Italy (n = 20) and France (n = 10). Harvard University (n = 18) and Osped Civile (n = 11) were the most prolific institutions. Ten journals produced all of the top 100 papers with "Radiology" and "AJR" making up the majority. SN Goldberg and T Livraghi were the most prolific authors. Nearly two thirds of the papers (n = 61) were published after 1990. This analysis identifies many of the landmark interventional radiology papers and provides a fascinating insight into the changing discourse within the field. It also identifies topics, authors and institutions which have impacted greatly on the specialty.

Choo, Carol C; Burton, André Ad

2018-06-07

The advent of mobile technology has ushered in an era in which smartphone apps can be used as interventions for suicidality. We aimed to review recent research that is relevant to smartphone apps that can be used for mindfulness interventions for suicidality in Asian youths. The inclusion criteria for this review were: papers published in peer-reviewed journals from 2007 to 2017 with usage of search terms (namely "smartphone application" and "mindfulness") and screened by an experienced Asian clinician to be of clinical utility for mindfulness interventions for suicidality with Asian youths. The initial search of databases yielded 375 results. Fourteen full text papers that fit the inclusion criteria were assessed for eligibility and 10 papers were included in the current review. This review highlighted the paucity of evidence-based and empirically validated research into effective smartphone apps that can be used for mindfulness interventions for suicidality with Asian youths. ©Carol C Choo, André AD Burton.

2018-02-01

The aim of this study is to present a review based on the literature and proceedings from selected telemedicine conferences. The review was developed using the PRISMA framework. The Embase and PubMed (updated until July 13, 2015) literature databases were searched for telemedicine-related terms and Poland. The literature search identified 129 eligible articles in the databases and 85 in conference proceedings until July 2015. Articles measured as a number of contributions per year presented a similar rising, fluctuating and almost parallel pattern. Fifty-nine percent of the reviewed papers were published in impacted journals. Almost half of all publications presented original papers. The published articles concerned mostly cardiology (16%), family medicine (15%) and pathology (11%). Conference proceedings papers concerned orthopedics (29%, significantly more frequent; p < 0.001) and cardiology (14%). Scientific activity of researchers and practitioners in Poland in the field of telemedicine is not high, but it is increasing over time. There is a tendency to present the research rather in high-quality journals instead of conferences before publication. The occurrence of individual medical specialty telemedicine in Poland may reflect country-specific needs.

Issues Regarding the Assimilation of Cloud and Precipitation Data

NASA Technical Reports Server (NTRS)

Errico, Ronald M.; Bauer, Peter; Mahfouf, Jean-Francois

2008-01-01

This is the authors' response to a set of criticisms regarding a previously published work. It briefly addresses the main criticisms. In particular, it explains why some papers identified as having some fundamental flaws were referenced in the original work without detailed exposition of those flaws. It also explains why parts of the conclusion criticized as being contradictory are, in fact, not. It further highlights the need for more publishing of scientific criticisms. In the December 2007, special issue of the Journal of Atmospheric Sciences devoted to the Workshop on Assimilation of Satellite Cloud and Precipitation Observations, the authors published an article summarizing the many critical issues that render observations of cloud and precipitation difficult to analyze. Essentially, these include the inaccuracies of both current instruments and the relationships between what is actually observed (infrared or microwave energy detected at the altitude of the satellite) to what is desired (e.g., estimates of cloud drop sizes or rain rates) and the chaotic nature of atmospheric behavior and the complex mathematics describing it. The paper also included recommendations for future research and brief descriptions of many previous works concerning the subject. One reader is now attempting to publish a criticism of that paper. Her three complaints are that there was insufficient explanation of the identification of some cited works as being fundamentally flawed, that as a review the paper should have referenced some works additional to those it did, and that two recommendations were contradictory. Each of these complaints is addressed briefly in this response. First we explain why a brief list of works cited in our paper were identified as "flawed" with only a brief explanation. The design and conduct of the experiments reported in those papers violate well-established fundamentals such that, once the errors are recognized, their interpretations are no longer supported. Unfortunately, over the years, no researchers have bothered to publish criticisms of those papers, such that there are now too many to address in any single paper not devoted to that purpose. Yet, those papers are so often cited that we could not simply ignore them. Furthermore, if we had cited them without warning our readers regarding their flaws, we would have perpetrated a great disservice. In our response, however, we do offer further explanation of why some details, neglected in these papers, are critical to proper scientific evaluation. Neither did we offer insufficient references. Although we intentionally did not claim to be a "review' paper, we did cite 100 papers. That number is approximately 5 times the usual amount cited in journal articles. Although we only referenced few papers published after 2005, that was because our manuscript was submitted in January 2006, with its final, editorially-reviewed form in June 2006. We therefore could not reference papers published after this date. The problem here is that our paper was "in press" for 18 months. Finally, we explain that a careful reading of our paper reveals that our recommendations are not contradictory. Essentially, although we recommend 2 very distinct research approaches, these are complimentary and either alone is insufficient to accelerate progress. In conclusion, we recommend that the scientific community expends greater effort in publishing careful scientific criticisms so that others do not face the same dilemma we did. Likely this requires some reward system for doing so.

To identify and analyse the 100 most cited papers on stress in nurses published in nursing journals. The number of citations an article receives is an index of its impact on the scientific community. An analysis of the most cited articles on stress in nursing would allow us to identify the most important articles and to obtain information about this area of knowledge. A retrospective bibliometric analysis. In 2016, 111 journals belonging to the "nursing" category were identified in the Science and Social Science Citation Index. A search was performed of the Science Core Collection Website for articles on stress published in these journals. The topic, type of article, publishing journal, countries and institutions of origin and year of publication were extracted from the articles. The impact factor, immediacy index, journal country and publisher and h index were collected from the Institute for Scientific Information. The citation density, citation tendency and Bradford's law were calculated. They identified articles were mostly empirical quantitative studies with a transversal design, published from 1975 - 2011 in 23 journals. They were signed by 233 authors, most of whom are English-speaking from the USA and UK. The core distribution of the publications comprises a single journal, the Journal of Advanced Nursing. The study of stress in nursing has shown increased visibility and recognition each decade. The most recent articles have the highest number of citations, are the highest in rank and have the higher citation densities. © 2018 John Wiley & Sons Ltd.

Publishing articles in a prestigious journal is a golden rule for university professors and researchers nowadays. Impact factor, journal rank, and citation count, included in Science Citation Index managed by Thomson Reuters Web of Science, are the most important indicators for evaluating the quality of academic journals. By listing the journals encompassed in the “Integrative and Complementary Medicine” category of Science Citation Index from 2003 to 2013, this paper examines the publication trends of journals in the category. The examination includes number, country of origin, ranking, and languages of journals. Moreover, newly listed or removed journals in the category, journal publishers, and open access strategies are examined. It is concluded that the role of journal publisher should not be undermined in the “Integrative and Complementary Medicine” category. PMID:26213508

To identify global research trends in the use of acupuncture to treat cerebral infarction. We performed a bibliometric analysis of studies on the use of acupuncture to treat cerebral infarction published during 2002-2011, retrieved from Scopus, using the key words of acupuncture and cerebral infarction or ischemic stroke. peer-reviewed articles on the use of acupuncture to treat cerebral infarction indexed in Scopus and published between 2002 and 2011; types of publications were original research articles, reviews, meeting abstracts, proceedings papers, book chapters, editorial material, and news items. articles that required manual searching or telephone access; documents that were not published in the public domain; and corrected papers. (a) Annual publication output; (b) language of publication; (c) type of publication; (d) key words of publication; (e) publication by research field; (f) publication by journal; (g) publication by country and institution; (h) publication by author; (i) most-cited papers between 2002 and 2006; and (j) most-cited papers between 2007 and 2011. A total of 160 publications on the use of acupuncture to treat cerebral infarction from 2002-2011 were retrieved from Scopus. The number of publications increased gradually over the 10-year study period; most were written in Chinese or English. Articles and reviews constituted the major types. The most frequent key word used was acupuncture. The most prolific journals in this area were Zhongguo Zhen Jiu and the Chinese Journal of Clinical Rehabilitation. Of the 160 publications retrieved, half came from Chinese authors and institutions. Tianjin University of Traditional Chinese Medicine was the most prolific research institute. Two papers were cited 30 times; they were published in 2002 and 2009, respectively. In the field of neuroscience, there is little literature on acupuncture for cerebral infarction. The most-cited papers were cited 30 times in the past 3 years. We believe that, with advances in the study of mechanisms in neurobiology, research on acupuncture will also advance and will become the concern of more scholars.

Haxby, James V

2012-08-15

In 2001, we published a paper on the representation of faces and objects in ventral temporal cortex that introduced a new method for fMRI analysis, which subsequently came to be called multivariate pattern analysis (MVPA). MVPA now refers to a diverse set of methods that analyze neural responses as patterns of activity that reflect the varying brain states that a cortical field or system can produce. This paper recounts the circumstances and events that led to the original study and later developments and innovations that have greatly expanded this approach to fMRI data analysis, leading to its widespread application.

Ghost marketing: pharmaceutical companies and ghostwritten journal articles.

PubMed

Moffatt, Barton; Elliott, Carl

2007-01-01

The use of ghostwriters by industry is subject to increasing public attention and scrutiny. This article addresses the practice and ethics of scientific ghostwriting. We focus on the type of ghostwriting that involves a pharmaceutical company hiring a medical education and communications company to write a paper favorable of their product, who then hires a well-known academic to publish it under his or her name without disclosing the paper's true origins. We argue that this practice is harmful both to the public and to the institutions of science and that it is not justified by an analogy to accepted scientific authorship practices. Finally, we consider ways to discourage the practice.

[Who finances medical research in Chile?].

PubMed

Reyes, H; Kauffmann, R; Goic, A

1995-10-01

To identify those institutions granting medical research in Chile, every issue of Revista Médica de Chile published between 1987 and 1994 was reviewed, under the assumption that a vast majority (over 70%) of papers released by Chilean authors in topics of internal medicine and related subspecialties would have been submitted for publication in this journal. This assumption was based in the solid prestige of Revista Médica de Chile among Chilean physicians and investigators: it is one of the oldest medical journals in the world (founded in 1872) and its inclusion in the most important international indexes (e.g. Index Medicus, Current Contents) qualifies it in the "mainstream literature". Papers classified as "Original Articles", "Clinical Experiences", "Review Articles", "Public Health", "Case Reports", "Clinical Laboratory", "Special Articles" and "Medical Education" were screened for acknowledgment of financial support beyond the resources needed for routine clinical work. Among 1,528 manuscripts published, 344 were "Original Articles" and 61.3% of them acknowledged special financial support. Five hundred and one manuscripts were "Clinical Experiences" and 21.5% of them received special financial support; similar proportions were detected in "Review Articles" and "Public Health" topics. The institution ranked as providing support most often was the "Fondo Nacional de Ciencias y Tecnología" (FONDECYT), a governmental fund that assigns resources to research in all areas of science and technology through a peer-reviewed nationwide annual contest. FONDECYT was identified as provider of financial support to 45.2% of the "Original Articles" and "Clinical Experiences"; Chilean universities were mentioned by 33.6% and other entities (including pharmaceutical companies, other national and foreign organizations) by 23.1%. The University of Chile was the main Chilean university mentioned in the acknowledgments. The proportion of papers receiving special financial support was lower in Revista Médica de Chile than in three leading journals from developed countries (70% of Articles published in Annals of Internal Medicine, 74% in Lancet and 78% in The New England Journal of Medicine) but this proportion has been steadily increasing since 1987. The increase has been due only to FONDECYT and it would be unreasonable to expect that this institution will maintain such an expansion indefinitely. Therefore, Chilean investigators should attract more resources from the universities, the pharmaceutical companies and other non-governmental institutions.

In 2009 the journal published in the region of 200 papers including reviews, editorials, opinion pieces and original papers that ran the full gamut of allergic disease. It is instructive to take stock of this output to determine patterns of interest and where the cutting edge lies. We have surveyed the field of allergic disease as seen through the pages of Clinical and Experimental Allergy (CEA) highlighting trends, emphasizing notable observations and placing discoveries in the context of other key papers published during the year. The review is divided into similar sections as the journal. In the field of Asthma and Rhinitis CEA has contributed significantly to the debate about asthma phenotypes and expressed opinions about the cause of intrinsic asthma. It has also added its halfpennyworth to the hunt for meaningful biomarkers. In Mechanisms the considerable interest in T cell subsets including Th17 and T regulatory cells continues apace and the discipline of Epidemiology continues to invoke a steady stream of papers on risk factors for asthma with investigators still trying to explain the post-second world war epidemic of allergic disease.

Origin of Neutron Stars

Brecher, K.

1999-12-01

The origin of the concept of neutron stars can be traced to two brief, incredibly insightful publications. Work on the earlier paper by Lev Landau (Phys. Z. Sowjetunion, 1, 285, 1932) actually predated the discovery of neutrons. Nonetheless, Landau arrived at the notion of a collapsed star with the density of a nucleus (really a "nucleus star") and demonstrated (at about the same time as, and independent of, Chandrasekhar) that there is an upper mass limit for dense stellar objects of about 1.5 solar masses. Perhaps even more remarkable is the abstract of a talk presented at the December 1933 meeting of the American Physical Society published by Walter Baade and Fritz Zwicky in 1934 (Phys. Rev. 45, 138). It followed the discovery of the neutron by just over a year. Their report, which was about the same length as the present abstract: (1) invented the concept and word supernova; (2) suggested that cosmic rays are produced by supernovae; and (3) in the authors own words, proposed "with all reserve ... the view that supernovae represent the transitions from ordinary stars to neutron stars (italics), which in their final stages consist of extremely closely packed neutrons." The abstract by Baade and Zwicky probably contains the highest density of new, important (and correct) ideas in high energy astrophysics ever published in a single paper. In this talk, we will discuss some of the facts and myths surrounding these two publications.

In some biomedical sciences, changes in patterns of collaboration and authorship have complicated the assignment of credit and responsibility for research. It is unclear if this problem of "promiscuous coauthorship" or "hyperauthorship" (defined as six or more authors) is also apparent in the applied research disciplines within sport and exercise science. This study documented the authorship and sampling of patterns of original research reports in three applied biomechanics (Clinical Biomechanics, Journal of Applied Biomechanics, and Sports Biomechanics) and five similar subdisciplinary journals within sport and exercise science (International Journal of Sports Physiology and Performance, Journal of Sport Rehabilitation, Journal of Teaching Physical Education, Measurement in Physical Education and Exercise Sciences, and Motor Control). Original research reports from the 2009 volumes of these biomechanics and sport and exercise journals were reviewed. Single authorship of papers was rare (2.6%) in these journals, with the mean number of authors ranging from 2.7 to 4.5. Sample sizes and the ratio of sample to authors varied widely, and these variables tended not to be associated with number of authors. Original research reports published in these journals in 2009 tended to be published by small teams of collaborators, so currently there may be few problems with promiscuous coauthorship in these subdisciplines of sport and exercise science.

In conventional image trading systems, images are usually stored unprotected on a server, rendering them vulnerable to untrusted server providers and malicious intruders. This paper proposes a conceptual image trading framework that enables secure storage and retrieval over Internet services. The process involves three parties: an image publisher, a server provider, and an image buyer. The aim is to facilitate secure storage and retrieval of original images for commercial transactions, while preventing untrusted server providers and unauthorized users from gaining access to true contents. The framework exploits the Discrete Cosine Transform (DCT) coefficients and the moment invariants of images. Original images are visually protected in the DCT domain, and stored on a repository server. Small representation of the original images, called thumbnails, are generated and made publicly accessible for browsing. When a buyer is interested in a thumbnail, he/she sends a query to retrieve the visually protected image. The thumbnails and protected images are matched using the DC component of the DCT coefficients and the moment invariant feature. After the matching process, the server returns the corresponding protected image to the buyer. However, the image remains visually protected unless a key is granted. Our target application is the online market, where publishers sell their stock images over the Internet using public cloud servers.

The frequency with which a scientific article is cited by other studies is one way to measure its academic influence. A comprehensive search was performed to identify journal articles in the otorhinolaryngology subject category of the 2013 Journal Citation Report Science Edition over the last 30 years (1985-2014). The 100 most cited articles were reviewed and basic information including the publication year, country of origin, source journal, article type and research field was collected. The 100 most cited articles were published in 15 of the 44 otorhinolaryngology journals. The number of citations per article ranged between 208 and 1559. The leading research field was otology and neurotology (n = 50), followed by rhinology (n = 23) and head and neck surgery (n = 11). Most papers originated in the USA (n = 64). The possibility of an article being cited is influenced by the publication language, country of origin and source journal.

Author disclosure of conflict of interest in vascular surgery journals.

Forbes, Thomas L

2011-09-01

Advances in vascular surgery are increasingly technology-driven, and the relationships between surgeons and the medical device industry can be complex. This study reviewed conflict of interest (COI) disclosure in the vascular surgery journals regarding several selected technology-driven topics, including endovascular stent grafts (EV), carotid artery stenting (CAS), and peripheral arterial interventions (PI), to suggest further directions. Authors' COI disclosures were reviewed from all clinical papers published in 2008 and 2009 in each of six vascular surgery journals, and pertaining to three selected topics (EV, CAS, and PI). Rate of COI disclosure was evaluated as a function of journal, topic, article type (randomized trial, case series, case report, review, or meta-analysis), and authors' region of origin. Secondarily, consistency of authors' disclosure was evaluated by reviewing papers by the same author and of the same topic. Six hundred thirty-five papers were reviewed from the six journals. A COI was declared in 125 (19.7%) of these papers. This rate differed between journals (range, 3.2%-34.1%; P < .0001). Rate of disclosure did not differ between topics (range, 12.8%-21.2%; P = .12), article type (range, 14.7%-30%; P = .28), or region of origin (range, 0%-33.3%; P = .09). There were 116 instances of the same author writing papers describing the same general topic. COI disclosure was consistent in the majority of these instances (72.4%), but inconsistent in 32 cases (27.6%). The most common (P = .006) inconsistencies involved the same type of article in different journals (46.9%), or in the same journal (25%). Rates of disclosure of COI, and inconsistencies in disclosure in the vascular surgery literature are at least partially due to differences in journals' reporting policies, while a smaller proportion of these inconsistencies are due to individual author behavior. Journals should adopt a consistent requirement for a separate COI declaration where all relevant financial arrangements are disclosed. Copyright © 2011 Society for Vascular Surgery.

Scientific research is an essential aspect in the ongoing development of medical education and improved patient care. Dissemination of findings is a pivotal goal of any health research study. The number of citations that a published article receives is reflective of the importance that paper has on clinical practice. To date, it is unknown which journals are most frequently cited as influencing the management of pelvic trauma. The aim of this study was to identify the top 50 publications relating to the management of pelvic trauma. The database of the Science Citation Index of the Institute for Scientific Information (1945 to 2016) was reviewed to identify the 50 papers most commonly cited. A total of 1535 papers were included. Of these, 31 papers were cited over 100 times with the top 50 cited 69 times or more. The top 50 were subjected to further analysis to identify the authors and institutions involved. The majority of these publications originated in the USA, followed by Canada. The most cited paper is "pelvic ring fractures-should they be fixed", published by Tile in 1988. We have identified and analysed the publications that have contributed most to the assessment and management of pelvic trauma over the past 50 years. We have also identified the researchers and institutions which have most influenced the evidence-based approach currently employed in the management of pelvic trauma.

The Comment of Colmenero asserts no change in Fs(Q,t) of the poly(ethylene oxide) (PEO) chains in blends with poly(methyl methacrylate) on crossing times of about 1-2 ns in data obtained by neutron scattering experiments and simulations. The assertion is opposite to that reported in the original papers where the neutron data and simulations were published. To make this point clear, we cite the data and the very statements made in the original papers concluding that indeed in the time interval from 60 ps to 1-2 ns the dynamics of PEO chain follows approximately the Rouse model, but becomes slower and departs from the Rouse model in the dependencies on time, momentum transfer, and temperature at longer times past tc = 1-2 ns. It is noteworthy that similar crossover of chain dynamics in entangled homopolymers at the ns time scale was found by neutron scattering.

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

A workshop on Processing, Microstructure and Performance of Materials was held at the University of Auckland, School of Engineering, on 8-9 April 2009. Organised by the Department of Chemical and Materials Engineering, University of Auckland, this meeting consisted of international participants and aimed at addressing the state-of-the-art research activities in processing, microstructure characterization and performance integrity investigation of materials. This two-day conference brought together scientists and engineers from New Zealand, Australia, Hong Kong, France, and the United Kingdom. Undoubtedly, this diverse group of participants brought a very international flair to the proceedings which also featured original research papers on areas such as Materials processing; Microstructure characterisation and microanalysis; Mechanical response at different length scales, Biomaterials and Material Structural integrity. There were a total of 10 invited speakers, 16 paper presentations, and 14 poster presentations. Consequently, the presentations were carefully considered by the scientific committee and participants were invited to submit full papers for this volume. All the invited paper submissions for this volume have been peer reviewed by experts in the various fields represented in this conference, this in accordance to the expected standards of the journal's Peer review policy for IOP Conference Series: Materials Science and Engineering. The works in this publication consists of new and original research as well as several expert reviews of current state-of-the art technologies and scientific developments. Knowing some of the real constraints on hard-copy publishing of high quality, high resolution images, the editors are grateful to IOP Publishing for this opportunity to have the papers from this conference published on the online open-access platform. Listed in this volume are papers on a range of topics on materials research, including Ferguson's high strain rate deformation studies of wood, Nebosky et al's manufacturing methods of tantalum metal implant material, Tan et al's self-healing materials, Gabbitas et al's work on titanium alloys and others. Also among the review papers, topics include that on small-scale plasticity by Ng and Ngan showing how distinct plasticity between micro- and macro-specimens can be interpreted by size-dependent dislocation activities; and the latest advancements in electron microscopy, with a special emphasis on its application to materials engineering. Niche areas such as cartilage, dental and biomineralisation research are also included in several of the papers, as a recognition of the rapidly growing interest in biological materials research and its clinical relevance. Decidedly a resounding success, the conference and this volume owes much to all the individuals, organising committee, helpers and participants, who have taken time out to put in the effort of organising the meeting, preparing the presentations and writing the papers.

How accurate are quotations and references in medical journals?

PubMed

de Lacey, G; Record, C; Wade, J

1985-09-28

The accuracy of quotations and references in six medical journals published during January 1984 was assessed. The original author was misquoted in 15% of all references, and most of the errors would have misled readers. Errors in citation of references occurred in 24%, of which 8% were major errors--that is, they prevented immediate identification of the source of the reference. Inaccurate quotations and citations are displeasing for the original author, misleading for the reader, and mean that untruths become "accepted fact." Some suggestions for reducing these high levels of inaccuracy are that papers scheduled for publication with errors of citation should be returned to the author and checked completely and a permanent column specifically for misquotations could be inserted into the journal.

This paper investigates the output feedback control problem of a class of nonlinear systems with sensor noise and actuator degradation. Firstly, by using the descriptor observer approach, the origin system is transformed into a descriptor system. On the basis of the descriptor system, a novel Proportional Derivative (PD) observer is developed to asymptotically estimate sensor noise and system state simultaneously. Then, by designing an adaptive law to estimate the effectiveness of actuator, an adaptive observer-based controller is constructed to ensure that system state can be regulated to the origin asymptotically. Finally, the design scheme is applied to address a flexible joint robot link problem. Copyright © 2016 ISA. Published by Elsevier Ltd. All rights reserved.

This paper introduced the Revised Tool for the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2), including the development and comparison with the original QUADAS, and illustrated the application of QUADAS-2 in a published paper related to the study on diagnostic accuracy which was included in systematic review and Meta-analysis. QUADAS-2 presented considerable improvement over the original tool. Confused items that included in QUADAS had disappeared and the quality assessment of the original study replaced by the rating of risk on bias and applicability. This was implemented through the description on the four main domains with minimal overlapping and answering the signal questions in each domain. The risk of bias and applicability with 'high','low' or 'unclear' was in line with the risk of bias assessment of intervention studies in Cochrane, so to replace the total score of quality assessment in QUADAS. Meanwhile, QUADAS-2 was also applicable to assess the diagnostic accuracy studies in which follow-up without prognosis was involved in golden standard. It was useful to assess the overall methodological quality of the study despite more time consuming than the original QUADAS. However, QUADAS-2 needs to be modified to apply in comparative studies on diagnostic accuracy and we hope the users would follow the updates and give their feedbacks on line.

Publication in a Brazilian journal by Brazilian scientists whose papers have international impact.

Meneghini, R

2010-09-01

Nine Brazilian scientists with an outstanding profile of international publications were invited to publish an original article in the same issue of a Brazilian Journal (Anais da Academia Brasileira de Ciências). The objective was to measure the impact of the papers on the number of citations to the articles, the assumption being that these authors would carry their international prestige to the Brazilian periodical. In a 2-year period there was a larger number of citations of these articles compared to others published in the same journal. Nevertheless, the number of citations in Brazilian journals did not equal the number of citations obtained by the other papers by the same authors in their international publications within the same 2-year period. The reasons for this difference in the number of citations could be either that less significant invited articles were submitted or that it was due to the intrinsic lack of visibility of the Brazilian journals, but this could not be fully determined with the present data. Also relevant was a comparison between the citations of Brazilian journals and the publication in Brazilian journals by these selected authors. A clear imbalance due to a remarkable under-citation of Brazilian authors by authors publishing in Brazilian journals raises the possibility that psychological factors may affect the decision of citing Brazilian journals.

To characterize the situation of pulmonology journals published in Latin America. A survey was conducted in a meeting sponsored by the Latin American Thoracic Society. Each journal editor presented a report and answered a questionnaire. Improving information acquisition is the main motivation for pulmonology societies to edit their own journals, whereas disseminating medical knowledge and reporting experiences are the main motivations for authors to submit papers. The most common failing in the manuscripts submitted is poor compliance with the journal guidelines. Improving author-editor-reviewer relationships would be the best strategy for improving the quality of manuscripts. Suggestions for improving Latin American journals included the following: promoting professionalism in editorial tasks; encouraging manuscript reviewers to be more meticulous; and embracing international norms for editing medical journals. The following major problems were reported: a lack of regular, appropriate periodicity of issues; a shortage of original papers that are considered 'milestones' in the specialty; a low rejection rate for submitted papers; a high turnover of editors. Based on our findings, we can make the following recommendations: although many journals are available in electronic form, they should also be maintained in print form; each journal should divulge its subscription fee, even if it is included in the annual society membership dues; although each Latin American country might decide to publish its own pulmonology journal, the feasibility of publishing a multinational Latin American pulmonology journal should be explored.

A number of papers since Rampino and Stothers published in Science 1984 have reported common periodicities in a wide range of climate, geomagnetic, tectonic and biological proxies, including marine extinctions. Single taper and multitaper spectral analysis of marine fluctuations between the Late Cretaceous and the Miocene replicates a number of the published harmonics. Whereas these common periodicities have been argued to have a galactic origin, this paper presents an alternative fractal model based on large scale fluctuations of the magnetic field of the Sun. The fluctuations follow a self-similar matrix of periodicities and the solutions of the differential equation allow for models to be constructed predicting extreme events for solar emissions. A comparison to major Phanerozoic extinction, climate and geomagnetic events, captured in the geological record, show a striking loop symmetry summarised in major 66 Ma irradiance and electromagnetic pulses from the Sun.

Although English is medicine's lingua franca, practising physicians in Germany express the need for articles in German. This study aimed at surveying the number and characteristics of German-language psychiatric journals in Germany. Journals were identified by the standard handbook "Fachmedien Gesundheit" as well as by an online and library search, and divided into specialty journals and general psychiatry journals. Volume 2009 of all general psychiatry journals was analyzed regarding form and content. In 2009 74 journals addressed psychiatrists, albeit many not exclusively. Ten were general psychiatry journals publishing 391 review articles and 97 original papers. They differed with regard to focus (science, education, health politics) and formal characteristics, such as circulation (500-30  000), share of academia-affiliated authors (39-93 %), female first-authors (13-44 %), COI statements (0-98 % of articles), and international visibility. While much of German psychiatric science appears in English, there are still a substantial number of original articles published in German, and there is a diverse psychiatric journal scene in Germany. © Georg Thieme Verlag KG Stuttgart · New York.

Optical spectroscopic technologies are increasingly used for cancer diagnostics. Feasibility of differentiation between malignant and healthy samples of human kidney using Fluorescence, Raman, MIR and NIR spectroscopy has been recently reported . In the present work, a simplification of NIR spectroscopy method has been studied. Traditional high-resolution NIR spectrometry was replaced by an optical sensor based on a set of light-emitting diodes at selected wavelengths as light sources and a photodiode. Two prototypes of the sensor have been developed and tested using 14 in-vitro samples of seven kidney tumor patients. Statistical evaluation of results using principal component analysis and partial least-squares discriminant analysis has been performed. Despite only partial discrimination between tumor and healthy tissue achieved by the presented new technique, the results evidence benefits of LED-based near-infrared sensing used for oncological diagnostics.

The Fleischner Society has published several recommendations for terms for thoracic imaging. The most recent glossary was released in 2008. One glossary in German language was published in 1996. This review provides an updated German glossary of terms for thoracic imaging. It closely adheres to the Fleischner Society terminology. In some instances adaptions to the usage of German language were necessary, as well as some additions of terms which were later defined or redefined. These deviations are summarized in a revision report. The Fleischner Society has published a revised version of her glossary of terms for thoracic imaging in 2008. This paper presents a German adaption of this glossary. Some terms not contained in the original version have been added. The general use of the presented terminology in radiological reports is recommended. © Georg Thieme Verlag KG Stuttgart · New York.

The pineal gland has interested humans from millenniums. In this paper we review back in the history and the evolution of the pineal gland surgery. Originally, this surgery used to carry a high rate of morbidity and mortality. Nowadays the development of the anesthetic, radiological, surgical and intensive care techniques have been responsible of an improvement of the surgical results and better quality of life. It is always interesting to know from where we come. Copyright © 2014. Published by Elsevier Masson SAS.

The cytochrome P450 (CYP450) enzyme family is involved in the oxidative metabolism of many therapeutic drugs and various endogenous substrates. These enzymes are highly polymorphic. Prevalence of CYP450 enzyme gene polymorphisms vary among different populations and substantial inter- and intra-ethnic variability in frequency of CYP450 enzyme gene polymorphisms has been reported. This paper provides an overview and investigation of CYP450 genotypic and phenotypic reports published in the Greek population.

For some time, the most of reports have been being disseminated by way of scientific journals, bibliometric studies therefore being fundamental to the characterization and evaluation thereof. The purpose of this study is that of characterizing the Revista Española de Salud Pública based on the original articles published therein throughout the 1991-2000 period. Original articles published in the Revista Española de Salud Pública throughout the 1991-2000 period, all inclusive. A study has been made of the following variables: number of original articles, collaboration index or number of signing authors per study, productivity index, geographical spread and main subject. Throughout the 1991-2000 period, 290 original studies (52.3%) of a total of 555 studies were published. The number of originals averaged 29 originals/year A 4.5 degree of collaboration was found to exist for this journal (number signing authors/number originals) for the period under study. The annual of originals by Autonomous Community reveals in the Autonomous Community of Madrid (20.7%), Autonomous Community of Valencia (16.4%), Andalusia (16.1%) and Catalunya (10.0%) have published studies every year throughout the ten-year period under study. The most prevalent subject of all was that related to "Communicable disease" (86 originals), Primary Health Care" (34) and "Environmental pollution" (21). Generally speaking, it apparently follows that the Revista Española de Salud Pública continues to fall within the output-related indicators of other Spanish and foreign journals and that it has also evolved in keeping with the trend proper of scientific output in the biomedical field. Although "Communicable diseases" are not the main cause of mortality, they continue being the main subject more frequently studied.

Inadvertently submitting a paper to a journal that is unlikely to publish it is a waste of resources and ultimately delays dissemination of one's research. A high proportion of manuscripts are rejected by their author's first-choice journal. The aim of the present work was to review guidance provided within the literature for journal selection that might minimize the chance of manuscript rejection. We also consider papers that encompass more than one main medical science and describe the selection process that we used with a paper that was published in Cardiovascular Endocrinology . A database search (Embase, PubMed and Medworm) was performed for all articles published in the scientific literature providing guidance on journal selection. Articles were identified that either had journal selection as their principal topic or included journal selection as part of a broader discussion of publishing. The relative performance of four free-to-use, web-based applications that claim to provide guidance on journal selection was compared. The searches identified 286 hits, of which 249 were in English. Of these papers, 16 discussed journal selection and a further 10 articles were identified from citations within the original 16 articles. Only one article described a comprehensive model for submission decision-making. Identification of appropriate candidate journals by various web-based applications was erratic, with the Jane database providing the most robust suggestions. Our work suggests that little attention has been focused in the scientific literature on the mechanisms that authors use to select a journal for their work. Nevertheless, scientists for the most part seem to have a good sense of where their papers are most likely to be accepted. Beyond ensuring that a manuscript fulfils all the target journal's requirements, the literature suggests that it is important to have an objective view of the scientific contribution or 'value' of your work.

The health of the Roma people: a review of the published literature.

PubMed

Hajioff, S; McKee, M

2000-11-01

The Roma people originated in northern India and have been known in Europe for nearly a thousand years. For much of that time they have been the subjects of discrimination and oppression, culminating in the extermination of half a million Roma in the Nazi death camps. While it is widely believed that the health of Roma people is often poorer than the majority population, these inequalities remain largely unresearched. Published literature on the health of the Roma people was identified using Medline. Opinion pieces were excluded, as were papers relating to anthropometry and to genetic markers. The resultant papers were analysed by country of study and by disease type or care group. Some 70% of papers identified related to just three countries; Spain and the Czech and Slovak Republics. Much literature concentrates upon communicable disease or reproductive health. The limited evidence suggests increased morbidity from non-communicable disease, but there is little published on this topic. Evidence on health care, though fragmentary, suggests poorer access to health services and uptake of preventative care. Published research on the health needs of the Roma population is sparse. The topics that have received attention suggest a focus on concepts of contagion or social Darwinism, indicating a greater concern with the health needs of the majority populations with which they live. There is a need for both further research into the health of Roma people; with particular emphasis on non-communicable disease; and also for interventions that improve Roma health. Such research must, however, be handled with sensitivity, recognising the social and political context of the society concerned.

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

To identify and discuss the findings of publications on mechanical behavior of maxillofacial prosthetic materials published since 1969. Original experimental articles reporting on mechanical properties of maxillofacial prosthetic materials were included. A two-stage search of the literature, electronic and hand search, identified relevant published studies up to May 2015. An extensive electronic search was conducted of databases including PubMed, Embase, Scopus, and Google Scholar. Included primary studies (n = 63) reported on tensile strength, tear strength, and hardness of maxillofacial prosthetic materials at baseline and after aging. The search revealed 63 papers, with more than 28 papers being published in the past 10 years, which shows an increased number of publications when compared to only 6 papers published in the 1970s. The increase is linear with significant correlation (r = 0.85). Such an increase reflects great awareness and continued developments and warrants more research in the field of maxillofacial prosthetic materials properties; however, it is difficult to directly compare results, as studies varied in maxillofacial prosthetic materials tested with various silicone elastomers being heavily investigated, standards followed in preparing test specimens, experimental testing protocols, and parameters used in setting simulated aging conditionings. It is imperative to overcome the existing variability by establishing unified national or international standards/specifications for maxillofacial prosthetic materials. Standardization organizations or bodies, the scientific community, and academia need to be coordinated to achieve this goal. In the meantime and despite all of these theoretically significant alternatives, clinical practice still faces problems with serviceability of maxillofacial prostheses. © 2016 by the American College of Prosthodontists.

The fifty highest cited papers in anterior cruciate ligament injury.

Vielgut, Ines; Dauwe, Jan; Leithner, Andreas; Holzer, Lukas A

2017-07-01

The anterior cruciate ligament (ACL) is one of the most common injured knee ligaments and at the same time, one of the most frequent injuries seen in the sport orthopaedic practice. Due to the clinical relevance of ACL injuries, numerous papers focussing on this topic including biomechanical-, basic science-, clinical- or animal studies, were published. The purpose of this study was to determine the most frequently cited scientific articles which address this subject, establish a ranking of the 50 highest cited papers and analyse them according to their characteristics. The 50 highest cited articles related to Anterior Cruciate Ligament Injury were searched in Thomson ISI Web of Science® by the use of defined search terms. All types of scientific papers with reference to our topic were ranked according to the absolute number of citations and analyzed for the following characteristics: journal title, year of publication, number of citations, citation density, geographic origin, article type and level of evidence. The 50 highest cited articles had up to 1624 citations. The top ten papers on this topic were cited 600 times at least. Most papers were published in the American Journal of Sports Medicine. The publication years spanned from 1941 to 2007, with the 1990s and 2000s accounting for half of the articles (n = 25). Seven countries contributed to the top 50 list, with the USA having by far the most contribution (n = 40). The majority of articles could be attributed to the category "Clinical Science & Outcome". Most of them represent a high level of evidence. Scientific articles in the field of ACL injury are highly cited. The majority of these articles are clinical studies that have a high level of evidence. Although most of the articles were published between 1990 and 2007, the highest cited articles in absolute and relative numbers were published in the early 1980s. These articles contain well established scoring- or classification systems. The identification of important papers will help current clinicians and scientists to get an overview on past and current trends in that special field of ACL injury and provides a basis for both further discussion as well as future research.

Even if not so ancient, the history of the heat engine efficiency at maximum power expression has been yet turbulent. More than a decade after the publication of the seminal article by Curzon and Ahlborn in 1975, two older works by Chambadal and Novikov were rediscovered, both dating from 1957. Then, some years ago, the name of Yvon arose from a textual reference to this famous relation in a conference article published in 1955. Thanks to a historical study of French-written books not published for a long time, and since never translated into other languages, we bring to light in this paper that this relation was actually first proposed by Henri B. Reitlinger in 1929.

Access to data and the information explosion: oral contraceptives and risk of cancer.

This report describes a technically feasible method to deal with the enormous volume of literature published regarding oral contraceptives. This subject was discussed in 3735 publications during the period from November 1977 through October 1980. Our findings showed that those papers reporting original, numeric relationships involving risk of cancer and use of oral contraceptives were one percent of the total 3735 publications. However, only seven of the 27 articles involved were authored by individuals from departments of obstetrics and gynecology. Further, only four of the 27 were published in journals devoted to obstetrics and gynecology. The analyses suggest a form of censorship taking place, in that the obstetrics/gynecology specialists do not have ready access to the primary data.

Illogical and unethical scientific sanctions against Iranian authors.

2013-01-01

Restriction of free submission of Iranian manuscripts is not a new matter. However, the recent political decision of the USA Office of Foreign Assets Control of the Department of the Treasury saying who can and who cannot publish scientific papers in journals is completely against free distribution of data in scholarly and scientific communities and scientific journals and publications which requires discussions and challenges with the statutory authorities. Publishers' mission requires bringing suit against this illogical and unethical decision. Science should not be involved in the political game of sanctions. Policies of governments and the origins of the manuscript, including the race, ethnicity, nationality, religion, and political belief of the authors should not affect the editorial decisions of scientific publications.

2016-05-01

We sought to investigate whether exposing scientific papers to social media (SM) has an effect on article downloads and citations. We randomized all International Journal of Public Health (IJPH) original articles published between December 2012 and December 2014 to SM exposure (blog post, Twitter and Facebook) or no exposure at three different time points after first online publication. 130 papers (SM exposure = 65, control = 65) were randomized. The number of downloads did not differ significantly between groups (p = 0.60) nor did the number of citations (p = 0.88). Adjusting for length of observation and paper's geographical origin did not change these results. There was no difference in the number of downloads and citations between the SM exposure and control group when we stratified for open access status. The number of downloads and number of citations were significantly correlated in both groups. SM exposure did not have a significant effect on traditional impact metrics, such as downloads and citations. However, other metrics may measure the added value that social media might offer to a scientific journal, such as wider dissemination.

To analyze the impact of articles published in English compared to those published in Spanish in multilingual Spanish biomedical journals. We analyzed the language of publication, the number of original articles, the nationality of the authors, the citations received, the citing article and the nationality of the citing authors among the articles published from 2008-2012 in 5 multilingual Spanish biomedical journals. The study included 4,296 documents, 85 of which were published in English (2%). The percentage of original articles and of non-Spanish authorship was significantly higher among these latter articles and they also achieved more citations and more citing articles per article published. The proportion of articles published in English by multilingual Spanish biomedical journals is low and they are more often originals signed exclusively by foreign authors and receive more citations than those published in Spanish, which are also more frequently made by foreign authors.

The publication of anesthesiology papers presents the importance of understanding the corresponding research activity. This research used the bibliographic method to investigate the publication trend in anesthesiology using Science Citation Index Expanded over the period 1995-2014. The journals listed in the subject category of anesthesiology in the 2014 Journal Citation Reports were selected, and bibliographic information was collected from Science Citation Index Expanded, with 128,003 papers published from 1995 to 2014. Only the document type "article" was analyzed. The productivity and impact of various journals, countries, and institutions are discussed. A total of 64,199 articles published from 1995 to 2014, with 1,084,491 cited times, were examined. The total number of articles published by journals showed a slight increase in the 2 nd decade. More than 45% of these articles were published by the top five journals, which have maintained their ranking over 2 decades. Most publications originated from North America and European countries, of which the United States had the highest number of publications and citations. Most of the institutions are academic universities and hospitals. More than half of the top 25 institutions (in rankings) are located in the United States, and Harvard University accounted the highest number of articles and citations among all institutions. The results reported here may aid clinicians and researchers to better understand the worldwide contribution of anesthesiology research activities over 2 decades. Copyright © 2016.

Sport prostheses are used by both upper- and lower-limb amputees while participating in sports and other physical activities. Although the number of these devices has increased over the past decade, no overview of the peer reviewed literature describing them has been published previously. Such an overview will allow specialists to choose appropriate prostheses based on available scientific evidence rather than on personal experience or preference. To provide an overview of the sport prostheses as they are described by the papers published in peer reviewed literature. Literature review. Four electronic databases were searched using free text and Medical Subject Headings (MESH) terms. Papers were included if they concerned a prosthesis or a prosthetic adaptation used in sports. Papers were excluded if they did not originate from peer reviewed sources, if they concerned prostheses for body parts other than the upper or lower limbs, if they concerned amputations distal to the wrist or ankle, or if they were written in a language other than English. Twenty-four papers were included in this study. The vast majority contained descriptive data and consisted of expert opinions and technical notes. Data concerning the energy efficiency, technical characteristics and special mechanical properties of prostheses or prosthetic adaptations for sports, other than running, are scarce.

Nutrition campaigns in Primary Health Care (PHC) play an important role in health promotion and the prevention and treatment of injuries. The scope of this paper is to chart and evaluate the scientific output of nutrition in Brazilian PHC. A search and review of the literature and papers was conducted on the PubMed and Lilacs databases, using key words related to PHC and nutrition. The studies were restricted to Brazil with the professionals or population assisted by PHC in the Brazilian Unified Health System and published prior to March 2011. The references in the selected articles were also consulted in order to identify additional studies. From the total of papers located, 68 were eligible and a further 49 were identified in the references lists, such that a total of 117 papers were analyzed. The studies reviewed were mostly original articles, using quantitative methodology, carried out by São Paulo University in that state and published from 2002 to 2011. The main issues were diagnosis seeking the evaluation of nutritional status involving children. The output in this field is growing, although there is a need to redirect the scope of future studies to a focus on intervention models and program evaluation.

Point-of-collection (POC) devices aim for a fast, on-site detection for medical and environmental purposes. In this area, microfluidic Paper-based Analytical Devices (μPADs) have recently gained popularity because these are potentially cheap and environmentally friendly to produce, and easy to use. From an analytical perspective, paper is well known for its use as a substrate for chromatography, but less known for its use in electrophoretic separations. With the recent interest in μPADs, most applications are based on rather simple assays with relatively few applications incorporating an analytical separation. The focus of this review is on paper-based electrophoresis, originating with the key developments in the 1940s and 1950s as well as the recent developments of electrophoretic μPADs, and concluding with a critical discussion of the opportunities and challenges for electrophoretic μPADS in the future.

Literature review. Merseyside ENT Research Collaborative. The abstracts of presentations at Otorhinolaryngology Research Society meetings are published in Clinical Otolaryngology. A structured search of PubMed was undertaken to identify published Otorhinolaryngology Research Society presentations. Publication rates. A total of 460 abstracts were identified. The interobserver reliability among reviewers was 98%. Of the total, 259 (56.3%) abstracts were published in peer-reviewed journals. The average time from Otorhinolaryngology Research Society presentation to publication was 27.7 months (median 23), which was not significantly different from the previous review. Publication by subspeciality was as follows: head and neck (45.6%), otology (30.5%), rhinology (22%) and others (1.9%). Most published Otorhinolaryngology Research Society presentations were published in Clinical Otolaryngology (22.4%), followed by the Journal of Laryngology and Otology (8.1%) and the Laryngoscope (7.3%). Clinical research was the most common category of abstracts being presented at Otorhinolaryngology Research Society meetings, followed by laboratory-based research. Over half (56.5%) of laboratory research presented were head and neck themed, while otology and rhinology predominated clinical research presentations. Over half (52.1%) of Otorhinolaryngology Research Society abstracts originated from units in the North of England. Bristol presented the most abstracts (30.1%), followed by Newcastle (25.1%). The publication rate of Otorhinolaryngology Research Society presentations remains high and many are subsequently published in high-impact factor otolaryngology journals. More Otorhinolaryngology Research Society presentations are now published in American and European journals. © 2015 John Wiley & Sons Ltd.

Crockett, Matthew T; Browne, Ronan FJ; MacMahon, Peter J; Lawler, Leo

2015-01-01

AIM: To define the 100 citation classic papers of interventional radiology. METHODS: Using the database of Journal Citation Reports the 40 highest impact factor radiology journals were chosen. From these journals the 100 most cited interventional radiology papers were chosen and analysed. RESULTS: The top paper received 2497 citations and the 100th paper 200 citations. The average number of citations was 320. Dates of publication ranged from 1953 - 2005. Most papers originated in the United States (n = 67) followed by Italy (n = 20) and France (n = 10). Harvard University (n = 18) and Osped Civile (n = 11) were the most prolific institutions. Ten journals produced all of the top 100 papers with “Radiology” and “AJR” making up the majority. SN Goldberg and T Livraghi were the most prolific authors. Nearly two thirds of the papers (n = 61) were published after 1990. CONCLUSION: This analysis identifies many of the landmark interventional radiology papers and provides a fascinating insight into the changing discourse within the field. It also identifies topics, authors and institutions which have impacted greatly on the specialty. PMID:25918585

[Translation of titles into English in Medicina Clínica: quality and influence of the Spanish language].

PubMed

Navarro, F A; Barnes, J

1996-03-02

Journals that are not published solely in English have the titles of papers translated into English, the international language of medicine. The aim of this paper is to analyse the accuracy and quality of such translations in Medicina Clínica and to assess the influence of the morphology and syntax of Spanish on the English versions of the titles. Two professional medical translators, one Spanish and the other English, each with a knowledge of both languages, compared the original Spanish and the English translations of the titles of the 292 papers and communications published in the 20 issues of volume 100 of Medicina Clínica. The discrepancies or "errors" were classified in five groups of increasing seriousness. Of the titles studied, 77% contained some sort of error (458 errors were detected). In 100 titles (34%) there were differences in meaning between the original Spanish and the English translations. Another 72 titles contained serious orthographical, lexical or grammatical mistakes, though the basic meaning was not distorted. Approximately a third of the lexical and grammatical errors were attributable to the direct influence of Spanish. The English translations of titles in Medicina Clínica contain numerous orthographical, lexical and gammatical mistakes. Serious errors of meaning in a number of translated titles could result in misinterpretation by readers who do not know Spanish. We recommend that the authors should play a part in the translation of the titles, as this should provide a simple and effective mean of improving the accuracy of the translations. Our comparison yielded much worse results than had been expected, which suggests that similar studies with other medical journals in Spanish and other languages would be justified.

There is widespread evidence that statistical methods play an important role in original research articles, especially in medical research. The evaluation of statistical methods and reporting in journals suffers from a lack of standardized methods for assessing the use of statistics. The objective of this study was to develop and evaluate an instrument to assess the statistical intensity in research articles in a standardized way. A checklist-type measure scale was developed by selecting and refining items from previous reports about the statistical contents of medical journal articles and from published guidelines for statistical reporting. A total of 840 original medical research articles that were published between 2007-2015 in 16 journals were evaluated to test the scoring instrument. The total sum of all items was used to assess the intensity between sub-fields and journals. Inter-rater agreement was examined using a random sample of 40 articles. Four raters read and evaluated the selected articles using the developed instrument. The scale consisted of 66 items. The total summary score adequately discriminated between research articles according to their study design characteristics. The new instrument could also discriminate between journals according to their statistical intensity. The inter-observer agreement measured by the ICC was 0.88 between all four raters. Individual item analysis showed very high agreement between the rater pairs, the percentage agreement ranged from 91.7% to 95.2%. A reliable and applicable instrument for evaluating the statistical intensity in research papers was developed. It is a helpful tool for comparing the statistical intensity between sub-fields and journals. The novel instrument may be applied in manuscript peer review to identify papers in need of additional statistical review.

Leaf mass per area is independent of vein length per area: avoiding pitfalls when modelling phenotypic integration (reply to Blonder et al. 2014).

It has been recently proposed that leaf vein length per area (VLA) is the major determinant of leaf mass per area ( MA), and would thereby determine other traits of the leaf economic spectrum (LES), such as photosynthetic rate per mass (A(mass)), nitrogen concentration per mass (N(mass)) and leaf lifespan (LL). In a previous paper we argued that this 'vein origin' hypothesis was supported only by a mathematical model with predestined outcomes, and that we found no support for the 'vein origin' hypothesis in our analyses of compiled data. In contrast to the 'vein origin' hypothesis, empirical evidence indicated that VLA and LMA are independent mechanistically, and VLA (among other vein traits) contributes to a higher photosynthetic rate per area (A(area)), which scales up to driving a higher A(mass), all independently of LMA, N(mass) and LL. In their reply to our paper, Blonder et al. (2014) raised questions about our analysis of their model, but did not address our main point, that the data did not support their hypothesis. In this paper we provide further analysis of an extended data set, which again robustly demonstrates the mechanistic independence of LMA from VLA, and thus does not support the 'vein origin' hypothesis. We also address the four specific points raised by Blonder et al. (2014) regarding our analyses. We additionally show how this debate provides critical guidance for improved modelling of LES traits and other networks of phenotypic traits that determine plant performance under contrasting environments. © The Author 2014.

Today if you use the Thomson-Reuters Science Citations Index to search for "aerosol*", across all scientific disciplines and years, with no constraints, and you sort by number of citations, you will find a 2005 paper published in the Journal of the Atmospheric Sciences in the top 20. This is the "The MODIS Aerosol Algorithm, Products and Validation". Although I am the first author, there are in total 12 co-authors who each made a significant intellectual contribution to the paper or to the algorithm, products and validation described. This paper, that algorithm, those people lie at the heart of a lineage of scientists whose collaborations and linked individual pursuits have made a significant contribution to our understanding of radiative transfer and climate, of aerosol properties and the global aerosol system, of cloud physics and aerosol-cloud interaction, and how to measure these parameters and maximize the science that can be obtained from those measurements. The 'lineage' had its origins across the globe, from Soviet Russia to France, from the U.S. to Israel, from the Himalayas, the Sahel, the metropolises of Sao Paulo, Taipei, and the cities of east and south Asia. It came together in the 1990s and 2000s at the NASA Goddard Space Flight Center, using cultural diversity as a strength to form a common culture of scientific creativity that continues to this day. The original algorithm has spawned daughter algorithms that are being applied to new satellite and airborne sensors. The original MODIS products have been fundamental to analyses as diverse as air quality monitoring and aerosol-cloud forcing. AERONET, designed originally for the need of validation, is now its own thriving institution, and the lineage continues to push forward to provide new technology for the coming generations.

Rail-related suicide is a relatively rare but extremely lethal method of suicide that can have far-reaching consequences. The aim of the systematic literature review was to analyze the existing literature on the effectiveness of rail-suicide prevention activities. Databases used were Scopus, Medline, and ProQuest. The search terms used were "suicid*," "prevent*," "rail*," or "train." English-language studies published in peer-reviewed journals between 1 January 1990 and 30 April 2015 that presented an overview of rail-related suicide prevention activities and included an analysis of effectiveness were used. We retrieved 1,229 results in the original search with nine papers presenting empirical evidence. Three studies in the review analyzed the effectiveness of platform screen doors and another three analyzed the installation of blue lights, two papers analyzed the effectiveness of suicide pits, and one included the influence of media reporting guidelines. Platform screen doors, suicide pits, blue lights, and improved media guidelines all have the potential to reduce rail-related suicide events and deaths. The review was restricted to English-language peer-reviewed papers published within the chosen time period. © 2016 John Wiley & Sons Australia, Ltd.

The case-cohort study design combines the advantages of a cohort study with the efficiency of a nested case-control study. However, unlike more standard observational study designs, there are currently no guidelines for reporting results from case-cohort studies. Our aim was to review recent practice in reporting these studies, and develop recommendations for the future. By searching papers published in 24 major medical and epidemiological journals between January 2010 and March 2013 using PubMed, Scopus and Web of Knowledge, we identified 32 papers reporting case-cohort studies. The median subcohort sampling fraction was 4.1% (interquartile range 3.7% to 9.1%). The papers varied in their approaches to describing the numbers of individuals in the original cohort and the subcohort, presenting descriptive data, and in the level of detail provided about the statistical methods used, so it was not always possible to be sure that appropriate analyses had been conducted. Based on the findings of our review, we make recommendations about reporting of the study design, subcohort definition, numbers of participants, descriptive information and statistical methods, which could be used alongside existing STROBE guidelines for reporting observational studies.

To identify global research trends of stem cell transplantation for treating Parkinson's disease using a bibliometric analysis of the Web of Science. We performed a bibliometric analysis of data retrievals for stem cell transplantation for treating Parkinson's disease from 2002 to 2011 using the Web of Science. (a) peer-reviewed articles on stem cell transplantation for treating Parkinson's disease which were published and indexed in the Web of Science; (b) type of articles: original research articles, reviews, meeting abstracts, proceedings papers, book chapters, editorial material and news items; (c) year of publication: 2002-2011. (a) articles that required manual searching or telephone access; (b) we excluded documents that were not published in the public domain; (c) we excluded a number of corrected papers from the total number of articles. (1) Type of literature; (2) annual publication output; (3) distribution according to journals; (4) distribution according to subject areas; (5) distribution according to country; (6) distribution according to institution; (7) comparison of countries that published the most papers on stem cell transplantation from different cell sources for treating Parkinson's disease; (8) comparison of institutions that published the most papers on stem cell transplantation from different cell sources for treating Parkinson's disease in the Web of Science from 2002 to 2011; (9) comparison of studies on stem cell transplantation from different cell sources for treating Parkinson's disease. In total, 1 062 studies on stem cell transplantation for treating Parkinson's disease appeared in the Web of Science from 2002 to 2011, almost one third of which were from American authors and institutes. The number of studies on stem cell transplantation for treating Parkinson's disease had gradually increased over the past 10 years. Papers on stem cell transplantation for treating Parkinson's disease appeared in journals such as Stem Cells and Experimental Neurology. Although the United States published more articles addressing neural stem cell and embryonic stem cell transplantation for treating Parkinson's disease, China ranked first for articles published on bone marrow mesenchymal stem cell transplantation for treating Parkinson's disease. From our analysis of the literature and research trends, we found that stem cell transplantation for treating Parkinson's disease may offer further benefits in regenerative medicine.

Postural Re-Education of Scoliosis - State of the Art (Mini-review).

A new development of correcting exercises has been derived from the original Schroth program in 2010 and the preliminary results have been published that year. Since then the program has been applied in some centers worldwide. As the original Schroth program was the only program so far to improve many signs and symptoms of scoliosis besides the angle of curvature (Cobb angle) it was interesting to look for the preliminary results of the recent development of scoliosis pattern specific corrective exercises derived from the original program, to see if similar effects can be achieved with this less complicated method. A manual search in Pubmed was conducted, using the key words, Schroth, rehabilitation, and idiopathic scoliosis. Three papers have been found describing the short-term results of this new development today called Schroth Best Practice program (SBP). The papers were reviewed and analyzed with respect to the outcome parameters used. Outcome parameters were Angle of Trunk Rotation (ATR), Vital Capacity (VC), surface topography, electromyography, stabilometry and Cobb angle before and after a course of treatment. There was a significant improvement of all parameters after the application of this new program in all the three papers in the short- to mid-term. Scoliosis corrective exercises are supported by two randomized controlled trials (RCT) and should regularly be applied in mild scoliosis at risk for progression. Unspecific exercises such as Yoga, Dobomed cannot be regarded as effective as exercises using a well defined scoliosis pattern specific corrective routine.

The Acid Test for Biological Science: STAP Cells, Trust, and Replication.

PubMed

Lancaster, Cheryl

2016-02-01

In January 2014, a letter and original research article were published in Nature describing a process whereby somatic mouse cells could be converted into stem cells by subjecting them to stress. These "stimulus-triggered acquisition of pluripotency" (STAP) cells were shown to be capable of contributing to all cell types of a developing embryo, and extra-embryonic tissues. The lead author of the publications, Haruko Obokata, became an overnight celebrity in Japan, where she was dubbed the new face of Japanese science. However, in the weeks that followed publication of the research, issues arose. Other laboratories and researchers (including authors on the original papers) found that they were unable to replicate Obokata et al.'s work. Closer scrutiny of the papers by the scientific community also suggested that there was manipulation of images that had been published, and Obokata was accused of misconduct. Those who should have been supervising her work (also her co-authors on the publications) were also heavily criticised. The STAP cell saga of 2014 is used as an example to highlight the importance of trust and replication in twenty-first century biological science. The role of trust in the scientific community is highlighted, and the effects on interactions between science and the public examined. Similarly, this essay aims to highlight the importance of replication, and how this is understood by researchers, the media, and the public. The expected behaviour of scientists in the twenty-first century is now more closely scrutinised.

Miller raised the hopes of understanding the origin of life when on 15 May, Science published his paper on the synthesis of amino acids under conditions that simulated primitive Earth's atmosphere. Miller had applied an electric discharge to a mixture of CH4, NH3, H2O, and H2 - believed at the time to be the atmospheric composition of early Earth. Surprisingly, the products were not a random mixture of organic molecules, but rather a relatively small number of biochemically significant compounds such as amino acids, hydroxy acids, and urea. With the publication of these dramatic results, the modem era in the study of the origin of life began.

OBJECTIVE: To identify global research trends in the use of acupuncture to treat cerebral infarction. DATA RETRIEVAL: We performed a bibliometric analysis of studies on the use of acupuncture to treat cerebral infarction published during 2002–2011, retrieved from Scopus, using the key words of acupuncture and cerebral infarction or ischemic stroke. SELECTION CRITERIA: Inclusion criteria: peer-reviewed articles on the use of acupuncture to treat cerebral infarction indexed in Scopus and published between 2002 and 2011; types of publications were original research articles, reviews, meeting abstracts, proceedings papers, book chapters, editorial material, and news items. Exclusion criteria: articles that required manual searching or telephone access; documents that were not published in the public domain; and corrected papers. MAIN OUTCOME MEASURES: (a) Annual publication output; (b) language of publication; (c) type of publication; (d) key words of publication; (e) publication by research field; (f) publication by journal; (g) publication by country and institution; (h) publication by author; (i) most-cited papers between 2002 and 2006; and (j) most-cited papers between 2007 and 2011. RESULTS: A total of 160 publications on the use of acupuncture to treat cerebral infarction from 2002–2011 were retrieved from Scopus. The number of publications increased gradually over the 10-year study period; most were written in Chinese or English. Articles and reviews constituted the major types. The most frequent key word used was acupuncture. The most prolific journals in this area were Zhongguo Zhen Jiu and the Chinese Journal of Clinical Rehabilitation. Of the 160 publications retrieved, half came from Chinese authors and institutions. Tianjin University of Traditional Chinese Medicine was the most prolific research institute. Two papers were cited 30 times; they were published in 2002 and 2009, respectively. CONCLUSION: In the field of neuroscience, there is little literature on acupuncture for cerebral infarction. The most-cited papers were cited 30 times in the past 3 years. We believe that, with advances in the study of mechanisms in neurobiology, research on acupuncture will also advance and will become the concern of more scholars. PMID:25317148

It is nearly 35 years since I gave the 7th Sir Frederick Bartlett lecture at Oxford University. This was published as a paper entitled Orienting of Attention in the Quarterly Journal (1980, 32: 3–25). The topic was then primarily in Psychology, but now equally often in Neuroscience. This paper summarizes the background of the reaction time methods used in the original paper and findings that emerged later on the sensory consequences of orienting, mainly in the visual system. It then discusses the brain network which is the source of the sensory amplification and other brain networks that are involved in attention. Next, it reviews studies of the development of attentional networks in early life. Finally, it indicates how the new tools available to explore the human brain can lead to further progress.

2004-10-01

Molecular biology has expanded the horizons of anaesthesia during the last 20 years and has led to an increase of basic science articles that are published in the specialised anaesthetic journals or originate in anaesthetic institutions. We searched for and analysed the specific features, such as year of publication, publishing journal, and country of origin, of all such molecular biology articles stored in the MEDLINE database during the period 1986-2002. We identified 1265 original articles that used molecular biology techniques; 223 (18%) of these articles were published in anaesthetic journals and 1042 (82%) articles in 556 other biomedical journals. While in the late 1980s only a few molecular biology articles were published each year by anaesthetic institutions, worldwide this number reached approximately 200 basic science articles by the end of 2002. The USA clearly dominates the field of anaesthesia with respect to molecular biology research with 839 (66%) such articles.

Twice-yearly meetings of The British Society of Rehabilitation Medicine (BSRM) take place at which posters and free papers are generated, as abstracts, to present novel research findings, audits and case reports. The aim of this study was to evaluate the academic value of these meetings, by determining the subsequent rate of publication in peer-reviewed journals of abstracts presented. This was compared to the publication rate of other European medical specialist society meetings. The authors used MEDLINE, PubMed and Google Scholar search engines to look for publication of abstracts presented at BSRM meetings within peer-reviewed journals over a 7-year period (2000-2006). The abstracts were categorised into sub-groups (original study, audit, review, case report and service description) to determine which type was more likely to be published. The above databases were used also to extract studies on publication rate of other medical specialties in Europe. In 7 years, a total of 251 abstracts (of which 152 are original studies) have been presented as free papers or posters in a total of 13 meetings. The publication rate for the described study categories were: total 34%, original study 52%, review 50%, case report 5%, audit 0% and service description 0%. Publication rates from other specialist meetings in Europe range from 10% to 70%. The average publication rate for an abstract submitted to a BSRM meeting is 34% for any abstract and 52% for an original study suggesting that the meeting is generating abstracts of comparable academic interest to other specialist societies.

Crisis, change and creativity in science and technology: chemistry in the aftermath of twentieth-century global wars.

Johnson, Jeffrey Allan

2011-07-01

This paper presents the organising ideas behind the symposium "Chemistry in the Aftermath of World Wars," held at the 23rd International Congress of History of Science and Technology, Budapest, 2009, whose theme was "Ideas and Instruments in Social Context." After first recounting the origins of the notion of "crisis" as a decisive turning point in general history as well as in the history of science, the paper presents war and its aftermath as a form of crisis that may affect science and technology, including chemistry, in a variety of contexts and leading to a variety of types of change. The twentieth-century world wars were exemplary forms of crisis, whose aftermaths shaped the contexts for decisive changes in modern chemistry, which continue to offer challenging opportunities for historical research. In discussing these, the paper cites selected current literature and briefly describes how the individual papers of the symposium, including the three papers published in this volume, approached these challenges.

[How can I keep up with my literature?].

PubMed

Vandenbroucke, J P

1998-03-28

To keep up with the literature, the author and his wife have personal home subscriptions to the 'big five' general medical journals, two top general science journals, and close to a dozen specialist journals. Two of the general medical journals are regularly read in more depth. Since computerized search systems permit almost immediate retrieval on whatever subject at whatever work location, the author keeps no filing system of the items of interest. For three (slowly growing) subjects that transgress the boundaries of the usual keywords of search systems, copies of papers are collected in piles: (a) important methodological papers (which may have been published anywhere, on any subject), (b) papers about concepts of the origin and evolution of diseases, and (c) papers of strong general interest. The disadvantage of not keeping track of the literature by a personal filing system is that the author regularly forgets about papers and books he already has; the advantage is that no time is spent keeping a personal filing system.

The "Big-Bang" for modern glial biology: Translation and comments on Pío del Río-Hortega 1919 series of papers on microglia.

The word "glia" was coined in the mid-19th century and defined as "the nerve glue". For decades, it was assumed to be a uniform matrix, until cell theorists raised the "neuron doctrine" which stipulated that nervous tissue was composed of individual cells. The term "astrocytes" was introduced in the late 19th century as a synonym for glial cells, but it was Santiago Ramón y Cajal who defined a "third element" distinct from glial cells (astrocytes) and neurons. It was not until 1919 when Pío del Río-Hortega, an alumnus of the Cajal School, introduced the modern terms we use today, and thoroughly described both "oligodendrocytes" and "microglia" to clearly distinguish them from astrocytes. In a series of four papers published that year in Spanish, Río-Hortega described the distribution and morphological phenotype of microglia. He also noted that these cells were the origin of the rod cells described earlier in pathologic tissue, and recognized that resting microglia transformed into an ameboid phenotype in different types of brain diseases and pathologies. He also noted the mesodermal origin of these cells and recognized their phagocytic capacity. We here provide the first English translation of these landmark series of papers, which paved the way for modern glial research. To heighten the value and accessibility of these classic papers and their original figures, an introduction to this critical period of neuroscience is provided, along with unpublished photographs. By adding comments to the translated text, we provide sufficient context so that contemporary scientists may fully appreciate it. GLIA 2016;64:1801-1840. © 2016 Wiley Periodicals, Inc.

The thesis is an integral part of postgraduate medical education in India. Publication of the results of the thesis in an indexed journal is desirable; it validates the research and makes results available to researchers worldwide. To determine publication rates in indexed journals, of works derived from theses, and factors affecting publication. Postgraduate theses submitted over a five-year period (2001-05) in a university medical college were analyzed in a retrospective, observational study. Data retrieved included name and gender of postgraduate student, names, department and hierarchy of supervisor and co-supervisor(s), year submitted, study design, sample size, and statistically significant difference between groups. To determine subsequent publication in an indexed journal, Medline search was performed up to December 2007. Chi square test was used to compare publication rates based on categorical variables; Student's t-test was used to compare differences based on continuous variables. One hundred and sixty theses were retrieved, forty-eight (30%) were published. Papers were published 8-74 (33.7+/-17.33) months after thesis submission; the postgraduate student was first author in papers from 26 (54%) of the published theses. Gender of the student, department of origin, year of thesis submission, hierarchy of the supervisor, number and department of co-supervisors, and thesis characteristics did not influence publication rates. Rate of publication in indexed journals, of papers derived from postgraduate theses is 30%. In this study we were unable to identify factors that promote publication.

Does a lack of design and repeatability compromise scientific criticism? A Response to Smith et al. (2009)

In a recent paper published in The Auk, Smith et al. (2009) raised serious concerns over an apparent lack of reproducibility in their study of stable hydrogen isotope values (δDf ) in raptor feathers. The authors based their concerns on results obtained from different laboratories to which they submitted original and blind “repeats” over a multiyear period. A regression of the original sample δD versus “repeat” measurements showed an increase in the magnitude of residuals with increasing δDf , especially for values greater than about −80‰ (Smith et al. 2009: fig. 2). Because of this, the authors “caution against the continued use of δDf for predicting geographic origin, and for addressing important conservation questions” (p. 41) and conclude that “it is counterproductive to move forward [with hydrogen isotopes in avian studies] without first establishing full confidence in the technique that underlies such insights and conservation recommendations” (p. 45). We disagree with these sentiments.

A mass spectrometry method for the determination of the species of origin of gelatine in foods and pharmaceutical products.

Gelatine is a component of a wide range of foods. It is manufactured as a by-product of the meat industry from bone and hide, mainly from bovine and porcine sources. Accurate food labelling enables consumers to make informed decisions about the food they buy. Since labelling currently relies heavily on due diligence involving a paper trail, there could be benefits in developing a reliable test method for the consumer industries in terms of the species origin of gelatine. We present a method to determine the species origin of gelatines by peptide mass spectrometry methods. An evaluative comparison is also made with ELISA and PCR technologies. Commercial gelatines were found to contain undeclared species. Furthermore, undeclared bovine peptides were observed in commercial injection matrices. This analytical method could therefore support the food industry in terms of determining the species authenticity of gelatine in foods. Crown Copyright © 2015. Published by Elsevier Ltd.

The health of the Roma people: a review of the published literature

PubMed Central

Hajioff, S.; McKee, M.

2000-01-01

BACKGROUND—The Roma people originated in northern India and have been known in Europe for nearly a thousand years. For much of that time they have been the subjects of discrimination and oppression, culminating in the extermination of half a million Roma in the Nazi death camps. While it is widely believed that the health of Roma people is often poorer than the majority population, these inequalities remain largely unresearched.
METHODS—Published literature on the health of the Roma people was identified using Medline. Opinion pieces were excluded, as were papers relating to anthropometry and to genetic markers. The resultant papers were analysed by country of study and by disease type or care group.
RESULTS—Some 70% of papers identified related to just three countries; Spain and the Czech and Slovak Republics. Much literature concentrates upon communicable disease or reproductive health. The limited evidence suggests increased morbidity from non-communicable disease, but there is little published on this topic. Evidence on health care, though fragmentary, suggests poorer access to health services and uptake of preventative care.
DISCUSSION—Published research on the health needs of the Roma population is sparse. The topics that have received attention suggest a focus on concepts of contagion or social Darwinism, indicating a greater concern with the health needs of the majority populations with which they live. There is a need for both further research into the health of Roma people; with particular emphasis on non-communicable disease; and also for interventions that improve Roma health. Such research must, however, be handled with sensitivity, recognising the social and political context of the society concerned.

Assessing the height of block for caesarean section over the past three decades: trends from the literature.

PubMed

Hoyle, J; Yentis, S M

2015-04-01

There are multiple methods of assessing the height of block before caesarean section under regional anaesthesia, and surveys of practice suggest considerable variation in practice. So far, little emphasis has been placed on the guidance to be gained from published research literature or textbooks. We therefore set out to investigate the methods of block assessment documented in published articles and textbooks over the past 30 years. We performed two searches of PubMed for randomised clinical trials with caesarean section and either spinal anaesthesia or epidural anaesthesia as major Medical Subject Headings. A total of 284 papers, from 1984 to 2013, were analysed for methods of assessment of sensory and motor block, and the height of block deemed adequate for surgery. We also examined 45 editions of seven anaesthetic textbooks spanning 1950-2014 for recommended methods of assessment and height of block required for caesarean section. Analysis of published papers demonstrated a wide variation in techniques, though there has been a trend towards the increased use of touch, and an increased use of a block height of T5 over the study period. Only 115/284 (40.5%) papers described the method of assessing motor block, with most of those that did (102/115; 88.7%) describing it as the 'Bromage scale', although only five of these (4.9%) matched the original description by Bromage. The required height of block recommended by textbooks has risen over the last 30 years to T4, although only four textbooks made any recommendation about the preferred sensory modality. The variation in methods suggested by surveys of practice is reflected in variation in published trials, and there is little consensus or guidance in anaesthetic textbooks. © 2014 The Association of Anaesthetists of Great Britain and Ireland.

There is a paucity of information about the oral and maxillofacial cytology-related articles published in a cytology journal. Journal of Cytology (JOC) is the official publication of Indian Academy of Cytologists. This study aimed to audit the oral and maxillofacial cytology-related articles published in JOC from 2007 to 2015 over a 9-year period. Bibliometric analysis of issues of JOC from 2007 to 2015 was performed using web-based search. The articles published were analyzed for type of article and individual topic of oral and maxillofacial cytology. The articles published were also checked for authorship trends. Of the total 93 published articles related to oral and maxillofacial cytology, original articles (43) and case reports (33) contribute the major share. The highest number of oral and maxillofacial cytology-related articles was published in 2014 with 17 articles and the least published year was 2010 with three articles. Among the oral and maxillofacial cytology-related articles published in JOC, diseases of salivary gland (26) followed by oral exfoliated cells (17), soft tissue tumors (7), round cell tumors (6) and spindle cell neoplasms (5) form the major attraction of the contributors. The largest numbers of published articles related to oral and maxillofacial cytology were received from Postgraduate Institute of Medical Education and Research, Chandigarh (5), and Jawaharlal Nehru Medical College, Aligarh (5). This paper may be considered as a baseline study for the bibliometric information regarding oral and maxillofacial cytology-related articles published in India.

[Contrastive analysis of Latin terms for denoting human organs and structural body parts and parts of organs in anatomy literature in English and Serbian].

Vukčević-Lacković, Biljana

2011-01-01

This paper is concerned with the analysis of the use of Latin terms in the field of human anatomy through the contrastive analysis of examples from anatomy atlases and textbooks, and research papers in the area of human anatomy in English and Serbian. The contrastive analysis of examples has highlighted a certain tendency towards the use of original Latin terms in anatomy literature in the Serbian language, while the tendency of anatomy literature in English is towards the use of English terms which most often have a Latin root. It has also been noted that Serbian literature, in addition to original Latin terms, uses a significant number of terms with a Latin root. The noted tendencies differ depending on the type of literature (anatomy atlas, textbook or research paper). A significantly greater uniformity in the use of terminology has been noted in editions in English as compared to the Serbian anatomy literature where a lack of such a uniform system is evident. Bearing in mind the ever increasing significance of the English language in the world of science, one of the conclusions of this paper is that these differences may be of practical significance for authors from Serbia looking to publish their work in English as well as for translators of medical literature.

To identify global research trends in three therapies for children with cerebral palsy. We performed a bibliometric analysis of studies on therapies for children with cerebral palsy from 2002 to 2011 retrieved from Web of Science. (a) peer-reviewed published articles on botulinum toxin, constraint-induced movement therapy, or acupuncture for children with cerebral palsy indexed in Web of Science; (b) original research articles, reviews, meeting abstracts, proceedings papers, book chapters, editorial material, and news items; and (c) publication between 2002 and 2011. (a) articles that required manual searching or telephone access; (b) documents that were not published in the public domain; and (c) a number of corrected papers from the total number of articles. (1) Number of publications on the three therapies; (2) annual publication output, distribution by journals, distribution by institution, and top-cited articles on botulinum toxin; (3) annual publication output, distribution by journal, distribution by institution, and top-cited articles on constraint-induced movement therapy; (4) annual publication, distribution by journal, distribution by institution, and top-cited articles on acupuncture. This analysis, based on Web of Science articles, identified several research trends in studies published over the past 10 years of three therapies for children with cerebral palsy. More articles on botulinum toxin for treating children with cerebral palsy were published than the articles regarding constraint-induced movement therapy or acupuncture. The numbers of publications increased over the 10-year study period. Most papers appeared in journals with a focus on neurology, such as Developmental Medicine and Child Neurology and Journal of Child Neurology. Research institutes publishing on botulinum toxin treatments for this population are mostly in the Netherlands, the United States of America, and Australia; those publishing on constraint-induced movement therapy are mostly in Australia and the United States of America; and those publishing on acupuncture are mostly in China, Sweden and the United States of America. Analysis of literature and research trends indicated that there was no one specific therapy to cure cerebral palsy. Further studies are still necessary.

The history of photosynthesis research can be found in original papers and books. However, a special history is available from the prefatory chapters and the personal perspectives of various researchers who published them in several journals over the last 40 years. We have compiled a list of such perspectives published since 1964. Selection is not easy, especially of authors who were not directly engaged in photosynthesis research; some are included for their special insights related to central issues in the study of photosynthesis. Our journal, Photosynthesis Research, contains other valuable historic data in the occasional tributes, obituaries and historical notes, that have been published. Lists of these items are included. This article ends by listing the Nobel prizes related to photosynthesis and the Kettering Awards for Excellence in Photosynthesis Research. Wherever possible, a web page address is provided. The web page addresses have been taken from the article 'Photosynthesis and the Web: 2001' by Larry Orr and Govindjee, available at http://www.life.uiuc.edu/govindjee/photoweb and at http://photoscience.la.asu.edu/photosyn/ photoweb/default.html.When I find a bit of leisureI trifle with my papers.This is one of the lesserfrailities.'- Horace, Satires I, IV.

Citation counts can identify landmark papers. The aim of this study was to identify and characterize the top-cited articles in the pediatric liver transplantation literature. A search strategy for the Scopus ® database was designed for pediatric liver transplantation publications from 1945 to 2014. The 50 top-cited articles were analyzed. Author co-citation analysis was performed using VOSviewer techniques. There were 2896 articles published between 1969 and 2015. The mean citation count of the top 50 cited articles was 166 (range 95-635). There were three case reports in this top-cited list. There were 15 collaborations in this top-cited list with nine being international. The top-cited publications originated in 12 countries, with the USA and the UK contributing 31 and seven articles, respectively. There were 14 authors with four or more publications in this list. There was a single author with nine publications in the top-cited list. These top-cited papers were found in 16 journals, with three journals collectively publishing over 50% of these publications. Pediatric liver transplantation research is an evolving entity. Surgical techniques and case reports are influential articles. Collaborations at a national and international level produce highly cited articles, which are found in influential journals. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

2015-01-01

There is a paucity of studies that compare the differences in published articles submitted from the East and the West in the area of neurogastroenterology and motility (NM). To compare the article topics from the East and the West which have been published, 5 Western (Gastroenterology, Gut, American Journal of Gastroenterology, American Journal of Physiology-Gastrointestinal and Liver Physiology, and Neurogastroenterology and Motility) and 3 Eastern gastrointestinal journals (Journal of Gastroenterology, Journal of Gastroenterology and Hepatology, and Journal of Neurogastroenterology and Motility) were selected based on the impact factor. Published papers were classified into 12 categories and 60 subcategories. The titles and abstracts of review articles, original articles, and meta-analyses from these journals were reviewed for the last 2 years (2013–2014). In case of Journal of Neurogastroenterology and Motility which is published quarterly, this search was performed for 5 years (2010–2014). Of the total 2656 reviewed articles, 842 (260 from the East and 582 from the West) were classified into the category of NM. The most frequently published papers from the Western researchers were categorized as brain-gut interaction, visceral hypersensitivity, and irritable bowel syndrome, whereas those from the Eastern researchers were categorized as gastroesophageal reflux disease, functional dyspepsia, and irritable bowel syndrome. This difference between the East and the West is not just due to the journal itself, but it also depends on the author’s affiliation and their ability to perform high quality research in the area of the NM. These data provide evidence for the research trend and give valuable information to the researchers for determining subjects for the study and for selecting proper journals for publishing their studies.

Malformation or dysmorphic syndromes are conditions that are defined by the combination of a set of major and minor malformations that generally have a genetic origin. We investigated the early Spanish descriptions of a large number of sydromes. We started the study from the definition in a classic treatise on the subject. Among the 60 selected syndromes studied, at least two articles of each syndrome among those published in Spain and for the first time were listed in the Spanish Medical Index. For years prior to 1970, it expanded The search was expanded to PubMed, for the years before 1970. We collected 64 articles that referred to 58 syndromes. Four articles were written during the first half of the twentieth century. Almost half of the works (n=30) appeared in the 1970's. The papers were published in ten Spanish pediatric, nine Spanish non-pediatric, three pediatric non-Spanish and two non-Spanish non-pediatric Journals. The Journals with the most articles published were Anales de Pediatría y Revista Española de Pediatría. The hospitals where the articles originate more often were Hospital La Paz, Madrid and Hospital Clinic, Barcelona. The rest of the works were written in 30 pediatric hospitals and two more in non-Spanish hospitals. The number of authors increased with the passage of time. Although there were potential limitations, we have identified what may be the first descriptions of 58 syndromes, among the 60 chosen initially. Copyright © 2012 Asociación Española de Pediatría.

Are C-reps contextual representations? A reply to Brewin and Burgess.

PubMed

Pearson, David G

2014-03-01

Brewin and Burgess (2013) argue that our recent papers investigating the role of contextual representations in intrusive memories do not pose a challenge to dual-representation theory as originally claimed (Pearson, 2012; Pearson, Ross, & Webster, 2012). Here I point out that their alternative explanation for our results can be rejected using data already published in both papers. I also argue that their definition of what constitutes a contextual representation renders their revised dual-representation theory incompatible with experimental results that have previously been argued in the literature to support it. Valuable though their contribution is, it does not impact on our main conclusion that abstract contextual representations serve to increase intrusive memories for traumatic material.

This article has been withdrawn at the request of the Editors. Soon after the publication of this paper was announced, several experts in the field contacted the Editors to report errors. After extensive review, the Editors unanimously concluded that the results are in obvious conflict with a proven scientific fact, i.e., violation of local realism that has been demonstrated not only theoretically but experimentally in recent experiments. On this basis, the Editors decided to withdraw the paper. As a consequence, pages 67-79 originally occupied by the withdrawn article are missing from the printed issue.

In a previous analysis of the country of origin of papers published in Naunyn-Schmiedeberg's Archives of Pharmacology, a major shift toward contributions from emerging market countries, was noticed in comparison of 2010 to 2001 publications. Repeating such analysis for 2012 publications in the journal confirmed this trend. An interesting new trend was the emerging presence of papers from a variety of Islamic countries including Egypt. Based on this trend, we shortly review the history and current structure of pharmacology in Egypt. It appears that the presence of Egyptian pharmacology in international journals including pharmacology journals has sharply been increasing over the last two decades. Challenges for a continuation of this encouraging trend are being discussed.

Lorenz Heister (1683-1758) was the major academic surgeon of the eighteenth century. He served as an army surgeon in a number of campaigns and eventually became the professor of anatomy and surgery at Altdorf University. In 1739, he published a comprehensive book on surgery that became the standard text on the subject. It was widely reprinted and translated into many languages. The English version was the first systematic treatise on surgery to appear in that language. The book has many chapters devoted to diseases of the mouth and their treatment.

Leo Kanner begins his landmark 1943 case series on autistic children by stating the condition was first brought to his attention in 1938. Recent letters to JADD have described this reference as "mysterious" and speculated it refers to papers published that year by Despert or Asperger. In fact, as Kanner goes on to state, 1938 is when he examined the first child in his case series. An exchange of letters with Despert and later writing by Kanner also point to the originality of his observations.

CALL FOR PAPERS: Special Issue on `Singular Interactions in Quantum Mechanics: Solvable Models'

2004-07-01

This is a call for contributions to a special issue of Journal of Physics A: Mathematical and General entitled `Singular Interactions in Quantum Mechanics: Solvable Models'. This issue should be a repository for high quality original work. We are interested in having the topic interpreted broadly, that is, to include contributions dealing with point-interaction models, one- and many-body, quantum graphs, including graph-like structures coupling different dimensions, interactions supported by curves, manifolds, and more complicated sets, random and nonlinear couplings, etc., as well as approximations helping us to understand the meaning of singular couplings and applications of such models on different parts of quantum mechanics. We believe that when the second printing of the `bible' of the field, the book Solvable Models in Quantum Mechanics by S Albeverio, F Gesztesy, the late R Høegh-Krohn and H Holden, appears it is the right moment to review new developments in this area, with the hope of stimulating further development of these extremely useful techniques. The Editorial Board has invited G Dell'Antonio, P Exner and V Geyler to serve as Guest Editors for the special issue. Their criteria for acceptance of contributions are as follows: bullet The subject of the paper should relate to singular interactions in quantum mechanics in the sense described above. bullet Contributions will be refereed and processed according to the usual procedure of the journal. bullet Papers should be original; reviews of a work published elsewhere will not be accepted. The guidelines for the preparation of contributions are as follows: bullet The DEADLINE for submission of contributions is 31 October 2004.

Mortimer Frank, Johann Ludwig Choulant, and the history of anatomical illustration.

PubMed

Feibel, Robert M

2018-01-01

Mortimer Frank (1874-1919) was an ophthalmologist in Chicago, Illinois. He published a number of papers on the history of medicine, and was secretary of the Chicago Society of the History of Medicine and editor of their Bulletin. His major contribution to the history of medicine relates to the history of anatomical illustration. The classic book on that subject had been published in 1852 in German by the physician and historian, Johann Ludwig Choulant (1791-1861). However, by Frank's time this text was both out dated and out of print. Frank took on the tremendous project of translating Choulant's German text into English as History and Bibliography of Anatomic Illustration in Its Relation to Anatomic Science and The Graphic Arts. He improved Choulant's text with the results of his and other scholars' research, greatly enlarging the text. Frank supplemented the original book with a biography of Choulant, essays on anatomists not considered in the original text, and an essay on the history of anatomical illustration prior to those authors discussed by Choulant. This book, now referred to as Choulant/Frank, has been reprinted several times, and is still useful as a reference in this field, though some of its research is now dated.

Influence of the Casserius Tables on fetal anatomy illustration and how we envision the unborn.

PubMed

Heilemann, Heidi A

2011-01-01

The paper demonstrates how visual representation of the fetus in early anatomy texts influenced the reader's perception of the unborn child as an autonomous being. The health, art, and history literatures were used as sources. Original texts and illustrations, with particular attention paid to the Casserius Tables, published by Andreas Spigelius in 1627, are discussed. A review of the literature was conducted to identify and analyze published renderings, reproductions, and discussion of images of the unborn child. Original anatomy atlases were consulted. Artists' renderings of a particularly vulnerable state of human life influenced early perceptions of the status of the unborn child. The images show fetuses as highly independent, providing a visual cue that life is fully formed in utero. The legacy of the Casserius Tables is that they are still able to capture our attention because they portray the idea of a fetus and newborn even more clearly than our modern representations of this charged topic. The use of deceptive realism provides the viewer with an accessible visual representation of the unborn child. These early anatomy illustrations continue to influence modern-day perception of the unborn child as a separate being, completely autonomous from the mother.

The influence of organic production on food quality - research findings, gaps and future challenges.

Although several meta-analysis studies have been published comparing the quality of food derived from organic and non-organic origin, it is still not clear if food from organic production per se can guarantee product-related added value to consumers. This paper aims to summarize the status quo in order to identify research gaps and suggest future research challenges. Organic food is described according to a quality model already published. The influence of organic production on food quality is structured in primary production and processing. Furthermore, organic food authentication is discussed. Organic food seems to contain fewer pesticide residues and statistically more selected health-related compounds such as polyphenols in plant products and polyunsaturated fatty acids in milk and meat products, but the health relevance for consumers is not clear yet. Comparing food from organic origin with so called 'conventional' food seems not to be appropriate, because 'conventional' is not defined. In organic food quality research a system approach is needed from which systemic markers can be selected. Research on the impact of processing technologies on the quality according to organic principles seems of high relevance, since most of the food is processed. © 2014 Society of Chemical Industry.

Zweideutigkeit about "Zweideutigkeit": Sommerfeld, Pauli, and the methodological origins of quantum mechanics

NASA Astrophysics Data System (ADS)

Seth, Suman

In early 1925, Wolfgang Pauli (1900-1958) published the paper for which he is now most famous and for which he received the Nobel Prize in 1945. The paper detailed what we now know as his "exclusion principle." This essay situates the work leading up to Pauli's principle within the traditions of the "Sommerfeld School," led by Munich University's renowned theorist and teacher, Arnold Sommerfeld (1868-1951). Offering a substantial corrective to previous accounts of the birth of quantum mechanics, which have tended to sideline Sommerfeld's work, it is suggested here that both the method and the content of Pauli's paper drew substantially on the work of the Sommerfeld School in the early 1920s. Part One describes Sommerfeld's turn away from a faith in the power of model-based (modellmässig) methods in his early career towards the use of a more phenomenological emphasis on empirical regularities (Gesetzmässigkeiten) during precisely the period that both Pauli and Werner Heisenberg (1901-1976), among others, were his students. Part two delineates the importance of Sommerfeld's phenomenology to Pauli's methods in the exclusion principle paper, a paper that also eschewed modellmässig approaches in favour of a stress on Gesetzmässigkeiten. In terms of content, a focus on Sommerfeld's work reveals the roots of Pauli's understanding of the fundamental Zweideutigkeit (ambiguity) involving the quantum number of electrons within the atom. The conclusion points to the significance of these results to an improved historical understanding of the origin of aspects of Heisenberg's 1925 paper on the "Quantum-theoretical Reformulation (Umdeutung) of Kinematical and Mechanical Relations."

Thomas McKeown and Archibald Cochrane: a journey through the diffusion of their ideas.

In the 1970s Thomas McKeown and Archibald L Cochrane were two of the most influential voices in criticizing the dominance of medical thinking. A bibliometric study of the citations to McKeown's The Role of Medicine: Dream, Mirage or Nemesis and Cochrane's Effectiveness and Efficiency: Random Reflections on Health Services was performed from the publication of each book until 1988 to study how their ideas have been disseminated. During the study period 430 papers in the Science Citation Index or the Social Sciences Citation Index cited Cochrane's book, 133 cited McKeown's, and 166 cited both. The citations came mainly from original papers published in journals of internal medicine or public health and epidemiology (35%) and written by authors from the United States or the United Kingdom. Cochrane's book was cited most frequently in medical journals, suggesting a higher degree of penetration of his ideas among medical scientists. Although the dominance of original papers among the citations suggests that these books have been important in stimulating new knowledge, the main problems that McKeown and Cochrane identified--namely, the relatively small impact of clinical medicine on health outcomes and the poor use of scientific methods in clinical practice--are still with us.

In the past decade, a large influx of migrants presented in Europe. Their country of origin was mainly either Syria or Eritrea. Public health institutions in host countries in Europe are challenged to screen and care for migrant populations with regard to infectious diseases. We performed a systematic literature review (according to PRISMA guidelines) to define the infectious disease profile of migrants originating in Syria and Eritrea. The search resulted in 825 papers of possible relevance for infectious diseases in migrants from Syria, of which, after screening, we included 35 in the systematic review. A further 265 papers of possible relevance for infectious diseases in Eritrean migrants were screened, of which we included 27 in the systematic review. In migrants from Syria, leishmaniasis was the most frequently reported infectious disease. In addition, colonisation with drug resistant, Gram-negativ bacteria was reported. In the Eritrean migrants the infectious disease most described in the selected papers was louse-borne relapsing fever. Other frequently reported infectious diseases were scabies and Plasmodium vivax malaria. Our systematic analysis defines the profiles of infectious diseases for migrants from Syria and Eritrea and serves as an evidence base for public health screening and care of presenting migrants.

The Falck-Hillarp, formaldehyde fluorescence method for the demonstration of monoamine neurons in a microscope was established in Lund, Sweden and published in 1962. In the same year Hillarp moved to Karolinska Institutet in Stockholm. Two years later Dahlström and Fuxe published the famous supplement in Acta Physiologica Scandinavica, describing the distribution of the dopamine, noradrenaline and serotonin cell groups in the rat brain. This landmark paper also represented an important contribution to an emerging discipline in neuroscience - chemical neuroanatomy. During the following years several modifications of the original method were developed, attempting to solve some shortcomings, one being the reproducible demonstration of noradrenaline nerve terminals in cortical regions. One result was the paper focused on in the present article, which also describes other efforts in the same direction going on in parallel, primarily, in Lund and Stockholm. As a result there was, in the mid 1970s, a fairly complete knowledge of the catecholamine systems in the rat brain. This article is part of a Special Issue entitled SI:50th Anniversary Issue.

With the number of scientific papers published in journals, conference proceedings, and international literature ever increasing, authors and reviewers are not only facilitated with an abundance of information, but unfortunately continuously confronted with risks associated with the erroneous copy of another's material. In parallel, Information Communication Technology (ICT) tools provide to researchers novel and continuously more effective ways to analyze and present their work. Software tools regarding statistical analysis offer scientists the chance to validate their work and enhance the quality of published papers. Moreover, from the reviewers and the editor's perspective, it is now possible to ensure the (text-content) originality of a scientific article with automated software tools for plagiarism detection. In this paper, we provide a step-bystep demonstration of two categories of tools, namely, statistical analysis and plagiarism detection. The aim is not to come up with a specific tool recommendation, but rather to provide useful guidelines on the proper use and efficiency of either category of tools. In the context of this special issue, this paper offers a useful tutorial to specific problems concerned with scientific writing and review discourse. A specific neuroscience experimental case example is utilized to illustrate the young researcher's statistical analysis burden, while a test scenario is purpose-built using open access journal articles to exemplify the use and comparative outputs of seven plagiarism detection software pieces.

Forty-two years of Revista Mexicana de Astronomía y Astrofísica: Some history and musings on the future

Allen, C.; Torres-Peimbert, S.

2017-07-01

After 42 years of continuously publishing the Revista Mexicana de Astronomía y Astrofísica, we cast a short retrospective view on its history and we share our plans for the future. RMxAA was founded in 1974. Founding editors were P. Pishmish, E. Mendoza and S. Torres-Peimbert. RMxAA has published original research papers in all areas of astronomy, astrophysics and related fields. Until 1994 RMxAA also published the proceedings of astronomical conferences held in México and Latin America. Since 1995 a Series devoted exclusively to such proceedings was founded, RMxAC, Revista Mexicana de Astronomía y Astrofísica (Serie de Conferencias). All papers submitted to RMxAA are sent to internationally recognized experts to be strictly refereed. RMxAA is included in Current Contents, Science Citation Index and other relevant international indexes. Both publications are fully integrated into the ADS. Their contents have always been freely available to the general public. All this ensures a wide international visibility, comparable to that of the best astronomical journals. The impact factor of RMxAA has varied over the years, mostly as a consequence of small number statistics. The average impact factor is about 2.4, far larger than that of all but a few Latin American scientific journals. The editorial independence of RMxAA, the fact that there are no page charges for authors, and that the printed version is distributed free of charge to astronomical libraries all over the world motivate us to look forward with optimism to many more years of publication. In view of recent developments in the scientific publishing field, we have applied to obtain the DOI for the published papers, and are in the process of becoming an all-electronic publication.

Measuring maternal satisfaction with maternity care: A systematic integrative review: What is the most appropriate, reliable and valid tool that can be used to measure maternal satisfaction with continuity of maternity care?

Perriman, Noelyn; Davis, Deborah

2016-06-01

The objective of this systematic integrative review is to identify, summarise and communicate the findings of research relating to tools that measure maternal satisfaction with continuity of maternity care models. In so doing the most appropriate, reliable and valid tool that can be used to measure maternal satisfaction with continuity of maternity care will be determined. A systematic integrative review of published and unpublished literature was undertaken using selected databases. Research papers were included if they measured maternal satisfaction in a continuity model of maternity care, were published in English after 1999 and if they included (or made available) the instrument used to measure satisfaction. Six hundred and thirty two unique papers were identified and after applying the selection criteria, four papers were included in the review. Three of these originated in Australia and one in Canada. The primary focus of all papers was not on the development of a tool to measure maternal satisfaction but on the comparison of outcomes in different models of care. The instruments developed varied in terms of the degree to which they were tested for validity and reliability. Women's satisfaction with maternity services is an important measure of quality. Most satisfaction surveys in maternity appear to reflect fragmented models of care though continuity of care models are increasing in line with the evidence demonstrating their effectiveness. It is important that robust tools are developed for this context and that there is some consistency in the way this is measured and reported for the purposes of benchmarking and quality improvement.

The objective of this study was to examine the type and content of Journal of Women's Health Physical Therapy (JWHPT) publications over the last decade. Content and bibliometric analysis of published literature. Component sections, such as the Section on Women's Health (SoWH) of the American Physical Therapy Association provide content expertise to areas of specialty physical therapist practice, thereby supporting the dissemination of evidence for physical therapists to use. Closely aligned with the mission of the SoWH, JWHPT provides evidence reflecting this practice area. The purpose of our analysis was to examine publications within JWHPT to determine how closely JWHPT is meeting the mission and focus of section members. We used established bibliographic methodology to code and review manuscripts published online between 2005 and 2015 in JWHPT using established domains (article type, participant type, research design, study purpose, and area of focus). Total publications and proportion of publications based on domain were described. Impact by citation and author was examined using bibliometric software. Eighteen percent of the items published in JWHPT were original research papers submitted for the first time. Of those papers, the primary study design was cross-sectional experimental research, most commonly studying interventions. The primary practice area reported was management of incontinence. We suggest that a continued need to increase efforts for the submission and publication of a greater proportion of randomized controlled trials and metric articles.

Transmission loss of double panels filled with porogranular materials.

2009-12-01

Sound transmission through hollow structures found its interest in several industrial domains such as building acoustics, automotive industry, and aeronautics. However, in practice, hollow structures are often filled with porous materials to improve acoustic properties without adding an excessive mass. Recently a lot of interest arises for granular materials of low density that can be an alternative to standard absorbing materials. This paper aims to predict vibro-acoustic behavior of double panels filled with porogranular materials by using the patch-mobility method recently published. Biot's theory is a basic tool for the description of porous material but is quite difficult to use in practice, mostly because of the solid phase characterization. The original simplified Biot's model (fluid-fluid model) for porogranular material permitting a considerable reduction in data necessary for calculation has been recently published. The aim of the present paper is to propose a model to predict sound transmission through a double panel filled with a porogranular material. The method is an extension of a previous paper to take into account the porogranular material through fluid-fluid Biot's model. After a global overview of the method, the case of a double panel filled with expanded polystyrene beads is studied and a comparison with measurements is realized.

With this editorial note we would like to update you on the performance of the International Journal of Applied Earth Observation and Geoinformation (JAG) and inform you about changes that have been made to the composition of the editorial team. Our Journal publishes original papers that apply earth observation data for the management of natural resources and the environment. Environmental issues include biodiversity, land degradation, industrial pollution and natural hazards such as earthquakes, floods and landslides. As such the scope is broad and ranges from conceptual and more fundamental work on earth observation and geospatial sciences to the more problem-solving type of work. When I took over the role of Editor-in-Chief in 2012, I together with the Publisher set myself the mission to position JAG in the top-3 of the remote sensing and GIS journals. To do so we strived at attracting high quality and high impact papers to the journal and to reduce the review turnover time to make JAG a more attractive medium for publications. What has been achieved? Have we reached our ambitions? We can say that: The submissions have increased over the years with over 23% for the last 12 months. Naturally not all may lead to more papers, but at least a portion of the additional submissions should lead to a growth in journal content and quality.

Selected techniques in water resources investigations, 1965

Mesnier, Glennon N.; Chase, Edith B.

Increasing world activity in water-resources development has created an interest in techniques for conducting investigations in the field. In the United States, the Geological Survey has the responsibility for extensive and intensive hydrologic studies, and the Survey places considerable emphasis on discovering better ways to carry out its responsibility. For many years, the dominant interest in field techniques has been "in house," but the emerging world interest has led to a need for published accounts of this progress. In 1963 the Geological Survey published "Selected Techniques in Water Resources Investigations" (Water-Supply Paper 1669-Z) as part of the series "Contributions to the Hydrology of the United States."The report was so favorably received that successive volumes are planned, of which this is the first. The present report contains 25 papers that represent new ideas being tested or applied in the hydrologic field program of the Geological Survey. These ideas range from a proposed system for monitoring fluvial sediment to how to construct stream-gaging wells from steel oil drums. The original papers have been revised and edited by the compilers, but the ideas presented are those of the authors. The general description of the bubble gage on page 2 has been given by the compilers as supplementary information.

Deep transfer learning for automatic target classification: MWIR to LWIR

Publisher's Note: This paper, originally published on 5/12/2016, was replaced with a corrected/revised version on 5/18/2016. If you downloaded the original PDF but are unable to access the revision, please contact SPIE Digital Library Customer Service for assistance. When dealing with sparse or no labeled data in the target domain, transfer learning shows its appealing performance by borrowing the supervised knowledge from external domains. Recently deep structure learning has been exploited in transfer learning due to its attractive power in extracting effective knowledge through multi-layer strategy, so that deep transfer learning is promising to address the cross-domain mismatch. In general, cross-domain disparity can be resulted from the difference between source and target distributions or different modalities, e.g., Midwave IR (MWIR) and Longwave IR (LWIR). In this paper, we propose a Weighted Deep Transfer Learning framework for automatic target classification through a task-driven fashion. Specifically, deep features and classifier parameters are obtained simultaneously for optimal classification performance. In this way, the proposed deep structures can extract more effective features with the guidance of the classifier performance; on the other hand, the classifier performance is further improved since it is optimized on more discriminative features. Furthermore, we build a weighted scheme to couple source and target output by assigning pseudo labels to target data, therefore we can transfer knowledge from source (i.e., MWIR) to target (i.e., LWIR). Experimental results on real databases demonstrate the superiority of the proposed algorithm by comparing with others.

Data reuse and the open data citation advantage

PubMed Central

Vision, Todd J.

2013-01-01

Background. Attribution to the original contributor upon reuse of published data is important both as a reward for data creators and to document the provenance of research findings. Previous studies have found that papers with publicly available datasets receive a higher number of citations than similar studies without available data. However, few previous analyses have had the statistical power to control for the many variables known to predict citation rate, which has led to uncertain estimates of the “citation benefit”. Furthermore, little is known about patterns in data reuse over time and across datasets. Method and Results. Here, we look at citation rates while controlling for many known citation predictors and investigate the variability of data reuse. In a multivariate regression on 10,555 studies that created gene expression microarray data, we found that studies that made data available in a public repository received 9% (95% confidence interval: 5% to 13%) more citations than similar studies for which the data was not made available. Date of publication, journal impact factor, open access status, number of authors, first and last author publication history, corresponding author country, institution citation history, and study topic were included as covariates. The citation benefit varied with date of dataset deposition: a citation benefit was most clear for papers published in 2004 and 2005, at about 30%. Authors published most papers using their own datasets within two years of their first publication on the dataset, whereas data reuse papers published by third-party investigators continued to accumulate for at least six years. To study patterns of data reuse directly, we compiled 9,724 instances of third party data reuse via mention of GEO or ArrayExpress accession numbers in the full text of papers. The level of third-party data use was high: for 100 datasets deposited in year 0, we estimated that 40 papers in PubMed reused a dataset by year 2, 100 by year 4, and more than 150 data reuse papers had been published by year 5. Data reuse was distributed across a broad base of datasets: a very conservative estimate found that 20% of the datasets deposited between 2003 and 2007 had been reused at least once by third parties. Conclusion. After accounting for other factors affecting citation rate, we find a robust citation benefit from open data, although a smaller one than previously reported. We conclude there is a direct effect of third-party data reuse that persists for years beyond the time when researchers have published most of the papers reusing their own data. Other factors that may also contribute to the citation benefit are considered. We further conclude that, at least for gene expression microarray data, a substantial fraction of archived datasets are reused, and that the intensity of dataset reuse has been steadily increasing since 2003.

The advancement of knowledge is based on the results of previously conducted research studies, which are reflected in the reference sources listed in a scientific article. This study is aimed at studying the scientific information used in the Revista Española de Salud Pública based on the references cited in the original articles published during the 1991-2000 period. The data regarding the year and where published, document type, language and country in which published was taken from the reference sources listed in the 290 original articles published, the obsolescence, Price and isolation indexes being calculated, and the Bradford core distribution being established according to the source journals. The self-citing rate was also calculated. A total of 7465 references were cited in the Reference section of the 290 original articles. An average of 25.7 references were cited per article. The Price index was 40.7. The scientific articles showed an obsolescence index of 5, the books and book chapters having an index of 6. A total 50.6% of the citations were from studies published in Spanish. The isolation index of the references was 48.1. The first Bradford core is comprised of 10 journals, the first four of which are Spanish. The self-citing rate was 3.8%. The information consumption of the original articles published in the Revista Española de Salud Pública show parameters similar to those of other Spanish health sciences journals for those same years, and the parameters regarding which this Journal differs from other Spanish health sciences journals seem to be justified by those particular aspects unique to public health, which does not fall within the patterns inherent to the clinical disciplines.

To analyse the institutionalisation of nutrition sciences in Spain in the second half of the twentieth century, and evaluate the activities of the journal Anales de Bromatología. Descriptive bibliometric study of the original articles. Full names of the authors and the complete article title were recorded. Using key words, each article was assigned by consensus of the researchers to a single main subject in accordance with the thirteen subject areas addressed by the Spanish Society of Bromatology in its meetings. An analysis was conducted of the distribution and trends of general productivity indicators and their characteristics. A total of 917 original articles were published, with a mean of 20.8 papers/year. The subjects for which the highest percentage of articles was recorded were foreign substances in foods, foods of plant origin and nutrition. A total of 874 authors contributed, with a collaboration rate of 2.43 and a transience rate of 70.1%. Distribution of the number of authors per article was close to that indicated by Lotka's law of scientific productivity. The top twelve producers, predominantly women, participated in 49.9% of the articles published. The journal showed low productivity and was of an endogamous nature, with a predominance of authors related to the School of Bromatology in the Faculty of Pharmacy, at the Complutense University. The subjects addressed reflected the demands of the nutrition transition in Spain.

EDITORIAL: On plagiarism

Harris, Simon; Webb, Steve; Hendee, William R.

2008-03-01

Plagiarism Plagiarism is, we are pleased to observe, not a common occurrence in Physics in Medicine & Biology (PMB); however, like those responsible for all scientific journals, we are concerned about plagiarism, and very keen to prevent it. The Publications Committee of the International Organization of Medical Physics (IOMP) has prepared a generic editorial on plagiarism. The editorial is reproduced here (with permission of the IOMP), with slight modifications to enhance its relevance to the audience of PMB, along with our procedures for dealing with any cases of plagiarism should they ever arise. Plagiarism (from the Latin 'plagiare', 'to kidnap') is defined as 'the appropriation or imitation of the language, ideas, and thoughts of another author, and representation of them as one's original work' (the Random House Dictionary of the English Language—unabridged). Plagiarism is a serious breach of research ethics that, if committed intentionally, is considered research misconduct. Plagiarism in its most serious form is the passing off of all, or large sections, of another author's published paper as one's original work. If, following appropriate confidential investigation (see below), such a plagiarism is established, this will result in heavy sanctions including retraction of the article, up to a 5 year publication ban from PMB, and informing of employers and/or professional bodies (even after one offence). This may result in loss of research funding, loss of professional stature, and even termination of employment of the plagiarizing author(s). Plagiarism undermines the authenticity of research manuscripts and the journals in which they are published, and compromises the integrity of the scientific process and the public regard for science. Plagiarism violates the literary rights of the individuals who are plagiarized, and the property rights of copyright holders. Violation of these rights may result in legal action against the individual(s) committing plagiarism. Although plagiarism has been present since the beginning of science, it seems to be increasing because the internet facilitates finding and copying the work of others. As Editors we are aware of some astonishing plagiarisms in some other publications that fortunately are rare but which encourage us to be increasingly vigilant. It is possible to plagiarize not only the work of others, but also one's own work through re-use of identical or nearly identical portions of manuscripts without acknowledgement and without citation. Simultaneous or subsequent submission of similar manuscripts with only minor differences and without citation between the manuscripts is, unfortunately, a not uncommon practice by authors hoping to acquire multiple publications from a research project. PMB strongly discourages this practice and will act against it if the facts become known before publication. In extreme cases of self-plagiarism (duplicate publication of a (nearly) full paper which has already been published elsewhere in a peer-review journal) sanctions similar to those outlined above may be applied. Occasionally similar articles may legitimately be published in two journals, because the journals reach different audiences and both would be interested in the article. This practice must be approved by the editors of both journals, and the duplication must be acknowledged in each article. When the possibility of plagiarism exists (often through an allegation of plagiarism by the original author, a reviewer, or an interested third party), the journal's Editor and Publisher will act quickly (particularly if the article in question has already been published online or in print). We will examine the original material and the publication alleged to constitute plagiarism. If the Editor and Publisher conclude that no plagiarism has occurred, the accuser will be notified and no further action is necessary. If the evidence suggests that plagiarism may have occurred, then we will contact the accused authors (all of them), the authors whose work may have been plagiarized, and the copyright holder of the original material. The correspondence will include the alleged plagiarizing language and a copy of the original and suspected work. If all parties agree that plagiarism (whether intentional or unintentional) has occurred, a written letter of apology should be sent promptly by the offending author(s) to the Editor/Publisher and to the authors and copyright holder whose work has been plagiarized. If the offending work has been published, a notice of plagiarism, citing both the plagiarized and the offending articles, will be published in the next available issue of PMB. The plagiarizing authors shall agree that all dissemination of the offending article shall be accompanied by the notice of plagiarism. In the most serious cases of plagiarism, a retraction (erratum) will be published (in accordance with the STM guidelines on 'Preservation of the objective record of science', retraction is favoured over removal in virtually all cases), and further sanctions applied. If the offending work hasn't yet been published (i.e. it is detected by the referees), sanctions will still be applied. If the accused authors deny that plagiarism has occurred, the Editor and Publisher must explore the accusation further. The investigation will also involve the Journals Director and the Chief Scientific Adviser of IOP Publishing (who publish PMB on behalf of IPEM) and also the General Secretary of IPEM. All parties to the allegation will be encouraged to submit corroborating evidence, and the accused authors granted an opportunity (at no expense to the journal) to testify in person to defend themselves against the allegation. The investigation should be concluded as quickly as possible (particularly if the article in question has already been published online or in print). If the investigation of the allegation of plagiarism concludes in support of the allegation, then the process for the case where plagiarism is admitted shall be instituted. A retraction will be published in PMB, and the authors banned from publishing in PMB for a number of years. Further, in the most serious cases the Publisher will report the plagiarism to the guilty parties' employer, and/or professional organization. If the investigation rules against the accusation of plagiarism, a letter stating this ruling shall be provided to the accuser, the authors accused of plagiarism, the authors of the original work, and the copyright holder. In either case, these actions should constitute closure of the allegation of plagiarism. An allegation of plagiarism is a very serious accusation, and should never be made lightly. On the other hand, self-policing is a major strength of the scientific community, and plagiarism should always be reported when it is suspected to have occurred. PMB reserves the right to amend the above detailed procedures should the practice of plagiarism worryingly become less rare than it is today.

Recently, Pierre Germain from CES - Silicon Europe published a comment on the paper "Volatile methylsiloxanes in personal care products - Using QuEChERS as a "green" analytical approach", raising concerns that the artefacts employed in the analysis of cyclic volatile methylsiloxanes (cVMS) were not adequately controlled, while using this example as an opportunity to emphasize the difficulties associated with siloxanes analyses in complex matrices such as personal care products (PCPs). We are now addressing these concerns and conveying some clarifications regarding the experiments performed to validate the analytical method adequately. Those details were not included in the original publication because the objective was the quantification of VMS in several PCPs. Copyright © 2017 Elsevier B.V. All rights reserved.

Pharmaceutical pricing in emerging markets: effects of income, competition, and procurement.

Danzon, Patricia M; Mulcahy, Andrew W; Towse, Adrian K

2015-02-01

This paper analyzes determinants of ex-manufacturer prices for originator and generic drugs across countries. We focus on drugs to treat HIV/AIDS, TB, and malaria in middle and low-income countries (MLICs), with robustness checks to other therapeutic categories and the full income range of countries. We examine the effects of per capita income, income dispersion, competition from originator and generic substitutes, and whether the drugs are sold to retail pharmacies versus tendered procurement by non-government organizations. The cross-national income elasticity of prices is 0.27 across the full income range of countries but is 0.0-0.10 between MLICs, implying that drugs are least affordable relative to income in the lowest income countries. Within-country income inequality contributes to relatively high prices in MLICs. Although generics are priced roughly 30% lower than originators on average, the variance is large. Additional generic competitors only weakly affect prices, plausibly because generic quality uncertainty leads to competition on brand rather than price. Tendered procurement that imposes quality standards attracts multinational generic suppliers and significantly reduces prices of originator and generic drugs, compared with their respective prices to retail pharmacies. © 2013 The Authors Health Economics Published by John Wiley & Sons Ltd.

EDITORIAL: A word from the new Editor-in-Chief A word from the new Editor-in-Chief

Mostowski, Jan

2011-01-01

TIn the autumn of 2010 I became the Editor-in Chief of European Journal of Physics (EJP). EJP is a place for teachers, instructors and professors to exchange their views on teaching physics at university level and share their experience. It is general opinion that no good research is possible without connection with good, high-quality teaching, at the university level in particular. Therefore excellence in physics teaching is important to the physics community. European Journal of Physics is proud of its contribution to achieving this goal. As Editor-in-Chief, I will continue to work to this general objective of the journal. We will publish articles on specific topics in physics, stressing originality of presentation and suitability for use in students'laboratories, lectures and physics teaching in general. We will also publish more pedagogical papers presenting the achievements of particular teaching methods. In addition, we will continue to publish special sections on particular areas of physics, as well as the annual special section on physics competitions. European Journal of Physics is in good shape. Due to the work of the previous editors and the publisher, the readership is high and growing steadily, and many excellent papers are being submitted and published. I hope that this positive trend for the journal will continue, and I will do my best to keep to this high standard. A few words about myself. I work in the Institute of Physics in Warsaw, Poland. My main research interests are in theoretical quantum optics and I have published about 80 research papers on this topic. For many years I was involved in teaching physics at university and in high school. I am a co-author of a textbook on physics for high-school students and of a problem book in quantum mechanics. For the last ten years, I have been involved in the International Physics Olympiad and over the last few years I have been a member of the Editorial Board of European Journal of Physics.

Bibliometric analysis of oral and maxillofacial cytology-related articles published in a cytology journal from India

Shamim, Thorakkal

2018-01-01

Background: There is a paucity of information about the oral and maxillofacial cytology-related articles published in a cytology journal. Journal of Cytology (JOC) is the official publication of Indian Academy of Cytologists. Objective: This study aimed to audit the oral and maxillofacial cytology-related articles published in JOC from 2007 to 2015 over a 9-year period. Materials and Methods: Bibliometric analysis of issues of JOC from 2007 to 2015 was performed using web-based search. The articles published were analyzed for type of article and individual topic of oral and maxillofacial cytology. The articles published were also checked for authorship trends. Results: Of the total 93 published articles related to oral and maxillofacial cytology, original articles (43) and case reports (33) contribute the major share. The highest number of oral and maxillofacial cytology-related articles was published in 2014 with 17 articles and the least published year was 2010 with three articles. Among the oral and maxillofacial cytology-related articles published in JOC, diseases of salivary gland (26) followed by oral exfoliated cells (17), soft tissue tumors (7), round cell tumors (6) and spindle cell neoplasms (5) form the major attraction of the contributors. The largest numbers of published articles related to oral and maxillofacial cytology were received from Postgraduate Institute of Medical Education and Research, Chandigarh (5), and Jawaharlal Nehru Medical College, Aligarh (5). Conclusion: This paper may be considered as a baseline study for the bibliometric information regarding oral and maxillofacial cytology-related articles published in India. PMID:29731569

Peer-Reviewed Veterinary Journals From Arabic-Speaking Countries: A Systematic Review.

PubMed

Robertson, Kristen M; Bowser, Jacquelyn E; Bernstein, Joshua; Aboul-Enein, Basil H

The prevalence of diseases of foodborne and zoonotic origin in Arabic-speaking countries highlights the importance of collaboration between human and animal health professionals. However, accessibility of research and evidence-based practices in these countries is not well characterized. This brief report determines the availability of professional veterinary journals within the Arabic-speaking region. An electronic search using 6 databases assessed for publication period, activity status, and available languages incorporated all aspects of veterinary medicine and specialties. Among 29 veterinary journals identified, the oldest current publication originated 63 years ago, with 10 journals currently interrupted or ceased. All 19 currently active journals are available electronically as open access, with 8 also offered in paper format. Veterinary journals published within Arabic-speaking countries are predominantly produced in Egypt, Iraq, and Sudan. Electronic access is lacking compared with English-speaking countries, and there is a lack of journals with an Arabic-language option. The reasons associated with language options in veterinary publications are not immediately apparent, yet may highlight differences among public health, health education, and zoonotic professionals and the populations they serve. Veterinary journals in Arabic-speaking countries do not adequately represent the overall region and are limited in access. Further evaluation of regional culture and publisher preferences is indicated to identify new collaboration opportunities among health professionals and local stakeholders.

Masters theses from a university medical college: Publication in indexed scientific journals

PubMed Central

Dhaliwal, Upreet; Singh, Navjeevan; Bhatia, Arati

2010-01-01

Background: The thesis is an integral part of postgraduate medical education in India. Publication of the results of the thesis in an indexed journal is desirable; it validates the research and makes results available to researchers worldwide. Aims: To determine publication rates in indexed journals, of works derived from theses, and factors affecting publication. Settings and Design: Postgraduate theses submitted over a five-year period (2001-05) in a university medical college were analyzed in a retrospective, observational study. Materials and Methods: Data retrieved included name and gender of postgraduate student, names, department and hierarchy of supervisor and co-supervisor(s), year submitted, study design, sample size, and statistically significant difference between groups. To determine subsequent publication in an indexed journal, Medline search was performed up to December 2007. Statistical Analysis: Chi square test was used to compare publication rates based on categorical variables; Student's t-test was used to compare differences based on continuous variables. Results: One hundred and sixty theses were retrieved, forty-eight (30%) were published. Papers were published 8-74 (33.7 ± 17.33) months after thesis submission; the postgraduate student was first author in papers from 26 (54%) of the published theses. Gender of the student, department of origin, year of thesis submission, hierarchy of the supervisor, number and department of co-supervisors, and thesis characteristics did not influence publication rates. Conclusions: Rate of publication in indexed journals, of papers derived from postgraduate theses is 30%. In this study we were unable to identify factors that promote publication. PMID:20195030

Christian, Joy

2016-10-01

This article has been withdrawn at the request of the Editors. Soon after the publication of this paper was announced, several experts in the field contacted the Editors to report errors. After extensive review, the Editors unanimously concluded that the results are in obvious conflict with a proven scientific fact, i.e., violation of local realism that has been demonstrated not only theoretically but experimentally in recent experiments. On this basis, the Editors decided to withdraw the paper. As a consequence, pages 67-79 originally occupied by the withdrawn article are missing from the printed issue. The publisher apologizes for any inconvenience this may cause. The full Elsevier Policy on Article Withdrawal can be found at http://www.elsevier.com/locate/withdrawalpolicy.

In the limelight of stars. Einstein, Mandl, and the origins of gravitational lens research (German Title: Im Rampenlicht der Sterne. Einstein, Mandl und die Ursprünge der Gravitationslinsenforschung)

NASA Astrophysics Data System (ADS)

Renn, Jürgen; Sauer, Tilman

Einstein's paper on gravitational lensing from 1936 was published only as a result of insistent prodding by the Czech amateur scientist Rudi Mandl. We discuss Mandl's role for the publication history of Einstein's paper and point out striking similarities between Mandl's situation in 1936 and Einstein's own position in 1912. At that time, Einstein himself had already considered the idea of gravitational lensing, as had been discovered some years ago through the identification of research notes from that period. Other early discussions of gravitational lensing by Lodge, Chwolson, Tikhov, Zwicky, Russell, and others were either only perceived or only written after Mandl had succeeded to persuade Einstein into publication.

Kepler's mathematization of Cosmology

Field, Judith V.

The paper concerns with mathematical knowledge of Johannes Kepler. A part of the paper describes the mathematical education of Kepler which includes the Euclidean geometry and texts by Ptolemy. The first He knew from the Proclus' Commentary which was published in 1533. The author is pointing out that Kepler's epistemology was close to Plato's. The "polyhedral archetype" is discussed in detail. The greatest error was in the case of Mercury (~20%) Kepler's reaction was otherwise absolutely what one would exopect of a theoretician in the twentieth century: he suggested that better observations would imoprouve matter. The author make an analogy with modern discussions on metal abundances in the outer layers of old stars. The author is mentioning also that the Kepler's version of Copernicus' system is noticeably different from Copernicus' original one, including important improvements.

Peter J. W. Debye - a whole life devoted to science.

Dalba, Giuseppe

2016-11-01

In 1915 P. Debye, one of the most prominent scientists in the field of condensed-matter physics and physical chemistry, published an X-ray scattering equation for randomly oriented scattering sites. This formula, since then used for describing the structure of powders, liquids and gases, has become a model for material analysis at the nanoscale. This paper re-examines briefly Debye's works on the origin and evolution of the scattering equation and its first uses. The career of the great scientist and some of his other numerous and diverse contributions to science are also reviewed. Additionally the paper addresses aspects of his life as a teacher, as a science manager and as a man, including the recent controversy about his conduct during the Third Reich regime.

On ‘lost’ indigenous etymological origins with the specific case of the name Ameiva

Angeli, Nicole Frances

2018-01-01

Abstract Modern biology builds upon the historic exploration of the natural world. Recognizing the origin of a species’ name is one path to honor the historic exploration and description of the natural world and the indigenous peoples that lived closely with organisms prior to their description. While digitization of historic papers catalogued in databases such as the Biodiversity Heritage Library (BHL) allows for searching of the first use and origin of names, the rapid pace of taxonomic publishing can occlude a thorough search for etymologies. The etymological origin of the genus name Ameiva is one such case; while unattributed in multiple recent works, it is of Tupí language origin. The first description was in the Historiae Rerum Naturalium Brasiliae by George Marcgrave (1648). Ameiva was the name used by Marcgrave’s Amerindian hosts in 17th century Dutch Brazil, where local people spoke the now extinct language Tupí. The Tupí origin was not lost, however, until as recently as the 2000s. Herein, the pre- and post-Linnaean use of the name Ameiva is traced and when the name is attributed to the Tupí language and to Marcgrave through time it is noted. The opportunity to discover and/or recover etymological origins, especially names from extinct and indigenous languages, provides insight into the early Western sciences. Careful study of etymology by naturalists is consistent with the idea that science is an evolving process with many predecessors to appreciate. PMID:29674919

Theoretical domains framework (TDF) provides an integrative model for assessing barriers to behavioral changes in order to suggest interventions for improvement in behavior and ultimately outcomes. However, there are other tools that are used to assess barriers. The objective of this study is to determine the degree of concordance between domains and constructs identified in two versions of the TDF including original (2005) and refined version (2012) and independent studies of other tools. We searched six databases for articles that studied barriers to health-related behavior changes of health care professionals or the general public. We reviewed quantitative papers published in English which included their questionnaires in the article. A table including the TDF domains of both original and refined versions and related constructs was developed to serve as a reference to describe the barriers assessed in the independent studies; descriptive statistics were used to express the results. Out of 552 papers retrieved, 50 were eligible to review. The barrier domains explored in these articles belonged to two to eleven domains of the refined TDF. Eighteen articles (36%) used constructs outside of the refined version. The spectrum of barrier constructs of the original TDF was broader and could meet the domains studied in 48 studies (96%). Barriers in domains of "environmental context and resources", "beliefs about consequences", and "social influences" were the most frequently explored in 42 (84%), 37 (74%), and 33 (66%) of the 50 articles, respectively. Both refined and original TDFs cataloged barriers measured by the other studies that did not use TDF as their framework. However, the original version of TDF explored a broader spectrum of barriers than the refined version. From this perspective, the original version of the TDF seems to be a more comprehensive tool for assessing barriers in practice.

The number of citations a scientific article receives provides a good indication of its impact within any given field. This bibliometric analysis aimed to identify the 100 most cited articles in Emergency Abdominal Surgery (EAS), to highlight key areas of interest and identify those that have most significantly shaped contemporary clinical practice in this newly evolving surgical specialty. This is of increasing relevance as concerns grow regarding the variable and suboptimal outcomes in Emergency General Surgery. The Thomson Reuters Web of Science database was used to search using the terms [Emergency AND Abdom* AND Surg*] to identify all English language, full manuscripts. Results were ranked according to citation number. The top 100 articles were further analysed by subject, author, journal, year of publication, institution, and country of origin. The median (range) citation number of the top 100 out of 7433 eligible papers was 131 (1569-97). The most cited paper (by Goldman et al., Massachusetts General Hospital, New England Journal of Medicine; 1569 citations) focused on cardiac risk stratification in non-cardiac surgery. The Journal of Trauma, Injury, Infection and Critical Care published the most papers and received most citations (n = 19; 2954 citations. The majority of papers were published by centres in the USA (n = 52; 9422 citations), followed by the UK (n = 13; 1816 citations). The most common topics of publication concerned abdominal aneurysm management (n = 26) and emergency gastrointestinal surgery (n = 26). Vascular surgery, risk assessment and gastrointestinal surgery were the areas of focus for 59% of the contemporary most cited emergency abdominal surgery manuscripts. By providing the most influential references this work serves as a guide to what makes a citable emergency surgery paper. Crown Copyright © 2016. Published by Elsevier Ltd. All rights reserved.

To describe the Peruvian scientific production in indexed journals in the Institute for Scientific Information (ISI) and the characteristics of the institutional collaborative networks. All papers published in the ISI database (Clinical Medicine collection) were included during 2000 to 2009 with at least one author with a Peruvian affiliation. The publication trend, address of corresponding author, type of article, institution, city (only for Peru), and country were evaluated. The collaborative networks were analized using the Pajek® software. 1210 papers were found, increasing from 61 in 2000 to 200 in 2009 (average of 121 articles/year). 30.4% articles included a corresponding author from a Peruvian institution. The average of authors per article was 8.3. Original articles represented 82.1% of total articles. Infectious diseases-related journals concentrated most of the articles. The main countries that collaborate with Peru are: USA (60.4%), England (12.9%), and Brazil (8.0%). Lima concentrated 94.7% of the publications and three regions (Huancavelica, Moquegua and Tacna) did not register any publication. Only two universities published more than one article/year and four institutions published more than 10 articles/year. Universidad Peruana Cayetano Heredia published 45% of the total number of articles, being the most productive institution and which concentrated the most number of collaborations with foreign institutions. The ministry of Health--including all dependencies--published 37.3% of the total number of publications. There is a higher level of collaboration with foreign institutions rather than local institutions. The Peruvian scientific production in medicine represented in the ISI database is very low but growing, and is concentrated in Lima and in a few institutions. The most productive Peruvian institutions collaborate more intensively with foreign journals rather than local institutions.

2016-05-03

Purpose The purpose of this paper is to explore selective leadership approaches in the context of dentistry in the UK. Design/methodology/approach This is a conceptual paper utilising published sources from relevant literature about leadership theory and practice and the policy background to dentistry in the UK. Findings This paper suggests that there is merit in identifying and applying an eclectic mix of leadership theory to the case of dentistry. It offers insight into individual aspects of the leadership role for dentists and applies this to the dental context. It also contrasts these individual approaches with shared leadership and suggests this may also be relevant to dentistry. It highlights the fact that leadership will be of growing concern for dentistry in the light of recent policy changes. Research limitations/implications This paper points out that there are developmental implications depending on the particular approach taken. It argues that leadership development will become increasingly important in dentistry in the UK. Originality/value This paper addresses a topic that has so far received limited attention in the literature.

Unpublished draft paper on sexuality by Donald Meltzer.

Editor's note: Albert Mason discovered an unpublished paper by Donald Meltzer dating from around 1968 and has made the text available to the IJP. He writes "my best guess is that Meltzer gave me the paper to read/approve about the time I was preparing to move to Los Angeles (1968-69) and that I hastily packed it away with other papers. It got buried, and only came to light recently, kind of like a lost score that turns up in someone's attic!" The patient Meltzer discusses in his paper is a patient who Dr Mason treated for approximately 11 years, and about whom Dr Mason consulted with Dr Meltzer early in the treatment. Dr Mason has also provided the original report he wrote about the patient in the 1960s. Following an introduction by Dr Abbot Bronstein, we have published extracts from Dr Mason's report, including the following: details about the case, the two dreams which Dr Mason believes were 'turning point dreams', and a third dream called the 'hula hula dream', as well as the clinical material leading up to it.

There is an ongoing interest in the society in promoting gender equality and in women integration in research activities. The purpose of this work is to identify from a gender perspective the bibliometric characteristics of articles published in Revista de Neurología journal during the 2002-2006 period. Records were obtained from Science Citation Index database of ISI-Thomson platform. The following indicators were determined, disaggregated by gender: year of publication, type of document, number and order of signatures, number of collaborators, signature/papers index and in the institutional and geographical level. 4527 authors were identified, 2614 (57.74%) men and 1913 (42.,26%) women. The highest women's participation took place in original articles (39.01% of signatures). 44.5% of authors with one published article were women, while 'big women producers' (those with more than 9 articles) only were 16.67%. A greater productivity in men and a greater rate of collaboration in women has been detected. Scientific activity studies disaggregated by gender give an essential information in order to establish the basis of a scientific policy for promoting the woman as researcher. The evolution in the number of female authors in Revista de Neurología journal does not present an aiming growth to reach the parity in the next years. A low presence of women in positions of high productivity has been detected, whose causes should be identified.

The rapid development of analytical methods in the last four decades has led to the discovery of a fascinating diversity of defensive chemicals used by termites. The last exhaustive review on termite defensive chemicals was published by G.D. Prestwich in 1984. In this text, we aim to fill the gap of the past 25 years and overview all of the relevant primary sources about the chemistry of termite defense (126 original papers, see Fig. 1 and online supplementary material) along with related biological aspects, such as the anatomy of defensive glands and their functional mechanisms, alarm communication, and the evolutionary significance of these defensive elements.

Reproducibility is a pillar of the scientific endeavour. We view computer simulations as laboratories for electronic experimentation and therefore as tools for science. Recent studies have addressed model reproduction and found it to be surprisingly difficult to replicate published findings. There have been enough failed simulation replications to raise the question, 'can computer models be fully replicated?' This paper answers in the affirmative by reporting on a successful reproduction study using Mathematica, Repast and Swarm for the Beer Game supply chain model. The reproduction process was valuable because it demonstrated the original result's robustness across modelling methodologies and implementation environments.

Modeling and simulation of soft sensor design for real-time speed estimation, measurement and control of induction motor.

PubMed

Etien, Erik

2013-05-01

This paper deals with the design of a speed soft sensor for induction motor. The sensor is based on the physical model of the motor. Because the validation step highlight the fact that the sensor cannot be validated for all the operating points, the model is modified in order to obtain a fully validated sensor in the whole speed range. An original feature of the proposed approach is that the modified model is derived from stability analysis using automatic control theory. Copyright © 2012 ISA. Published by Elsevier Ltd.

Recognition that psychological and behavioral factors play an important role in insomnia has led to increased interest in therapies targeting these factors. A review paper published in 1999 summarized the evidence regarding the efficacy of psychological and behavioral treatments for persistent insomnia. The present review provides an update of the evidence published since the original paper. As with the original paper, this review was conducted by a task force commissioned by the American Academy of Sleep Medicine in order to update its practice parameters on psychological and behavioral therapies for insomnia. A systematic review was conducted on 37 treatment studies (N = 2246 subjects/patients) published between 1998 and 2004 inclusively and identified through Psyclnfo and Medline searches. Each study was systematically reviewed with a standard coding sheet and the following information was extracted: Study design, sample (number of participants, age, gender), diagnosis, type of treatments and controls, primary and secondary outcome measures, and main findings. Criteria for inclusion of a study were as follows: (a) the main sleep diagnosis was insomnia (primary or comorbid), (b) at least 1 treatment condition was psychological or behavioral in content, (c) the study design was a randomized controlled trial, a nonrandomized group design, a clinical case series or a single subject experimental design with a minimum of 10 subjects, and (d) the study included at least 1 of the following as dependent variables: sleep onset latency, number and/or duration of awakenings, total sleep time, sleep efficiency, or sleep quality. Psychological and behavioral therapies produced reliable changes in several sleep parameters of individuals with either primary insomnia or insomnia associated with medical and psychiatric disorders. Nine studies documented the benefits of insomnia treatment in older adults or for facilitating discontinuation of medication among chronic hypnotic users. Sleep improvements achieved with treatment were well sustained over time; however, with the exception of reduced psychological symptoms/ distress, there was limited evidence that improved sleep led to clinically meaningful changes in other indices of morbidity (e.g., daytime fatigue). Five treatments met criteria for empirically-supported psychological treatments for insomnia: Stimulus control therapy, relaxation, paradoxical intention, sleep restriction, and cognitive-behavior therapy. These updated findings provide additional evidence in support of the original review's conclusions as to the efficacy and generalizability of psychological and behavioral therapies for persistent insomnia. Nonetheless, further research is needed to develop therapies that would optimize outcomes and reduce morbidity, as would studies of treatment mechanisms, mediators, and moderators of outcomes. Effectiveness studies are also needed to validate those therapies when implemented in clinical settings (primary care), by non-sleep specialists. There is also a need to disseminate more effectively the available evidence in support of psychological and behavioral interventions to health-care practitioners working on the front line.

B. F. Skinner's contributions to applied behavior analysis

2005-01-01

Our paper reviews and analyzes B. F. Skinner's contributions to applied behavior analysis in order to assess his role as the field's originator and founder. We found, first, that his contributions fall into five categorizes: the style and content of his science, his interpretations of typical and atypical human behavior, the implications he drew from his science for application, his descriptions of possible applications, and his own applications to nonhuman and human behavior. Second, we found that he explicitly or implicitly addressed all seven dimensions of applied behavior analysis. These contributions and the dimensions notwithstanding, he neither incorporated the field's scientific (e.g., analytic) and social dimensions (e.g., applied) into any program of published research such that he was its originator, nor did he systematically integrate, advance, and promote the dimensions so to have been its founder. As the founder of behavior analysis, however, he was the father of applied behavior analysis. PMID:22478444

[Summary: from "psychical treatment" to psychoanalysis. Remarks on the misdating of an early text of Freud and publication of a previously unnoticed addition to it].

PubMed

Fichtner, Gerhard

2007-01-01

Freud's early article, "Psychical (or mental) treatment," first appeared in a health textbook for educated lay people. It was included in his Gesammelte Werke with the publication date of 1905. Subsequently, this date was questioned because the text dealt mainly with hypnosis and suggestion, so James Strachey, among others, erroneously changed it to 1890. This error is corrected in the present paper. Until now, no one noticed that a second edition of the textbook, which appeared in 1918-19, contained an amended version of Freud's original article in which he added a summary of psychoanalytic theory and practice. The first edition was published in 1905-06. However, Freud's contribution must have been written at a much earlier date. Its presumed date of composition is discussed. Freud's addition to the original text is reprinted in an appendix for the first time.

The Last Word: Magnetic Storm-Still an Adequate Name?

NASA Astrophysics Data System (ADS)

Daglis, Ioannis A.

The magnetic storm is the principal and most complex collective phenomenon in geospace. It involves the magnetic fields of the Sun and the Earth, as well as plasma originating in the solar and terrestrial atmosphere. Magnetic storms involve more than just the geomagnetic field, as the original perception suggests. They involve a variety of dynamic processes among which charged particle acceleration and electric current intensification are the most important. Is the name still adequate, or should we switch to something more general and wide-ranging, such as ``space storms,'' or ``geospace storms''? The oldest printed record of ``magnetic storms'' that I was able to find appears in a letter published in Annalen der Physik written by the famous explorer Alexander von Humboldt to Paul Erman. I located this paper in the amazingly rich library of the Air Force Research Laboratory at Hanscom Air Force Base in Massachusetts with the kind help of Mike Heinemann.

Nathaniel Everett Green: artist and astronomer

McKim, R. J.

N. E. Green, a well-known BAA member from the decade of the 1890s, managed to successfully combine his hobby with his profession as a landscape artist and art teacher. One-time drawing master to Queen Victoria, and exhibitor at the Royal Academy, Green became equally famous for his beautiful and realistic drawings of the planets, above all for his expedition to Madeira in 1877 to observe the perihelic opposition of Mars. He inevitably became an important figure in the early martian 'canal debate'. Green was an Original Member of the BAA who twice directed the early Saturn Section, and ultimately served as President in 1896-'98. In this paper Green's life and works are reviewed, together with new details of his instruments and his approach to painting and drawing. Opportunity has been taken to publish some more of his original work, in colour, for the very first time.

Georges Lemaître and Stigler's Law of Eponymy

NASA Astrophysics Data System (ADS)

Block, David L.

One of the greatest discoveries of modern times is that of the expanding Universe, almost invariably attributed to Hubble (Proceedings of the National Academy of Sciences of the United States of America 15:168, 1929). What is not widely known is that the original treatise by Lemaître (Annales de la Société Scientifique de Bruxelles, Sèrie A 47:49, 1927) contained a rich fusion of both theory and of observation. The French paper was meticulously censored when published in English: all discussions of radial velocities and distances, and the very first empirical determination of H 0 , were suppressed. Stigler's law of eponymy is yet again affirmed: no scientific discovery is named after its original discoverer (Merton, American Sociological Review 22(6):635, 1957). An appeal is made for a Lemaître Telescope naming opportunity, to honour the discoverer of the expanding universe.

Bute's "Botanical tables": dictated by nature.

Lazarus, Maureen H; Pardoe, Heather S

2009-10-01

In the final years of his life, after a long and turbulent political career, John Stuart, third Earl of Bute, was at last free to indulge in one of his passions: botany. The publication of Linnaeus's "Systema naturae" in 1735 threw the botanical world into disarray and academic argument raged throughout Europe. The production of the "Botanical tables" (1785) was an ambitious project to explain Bute's individual view of Linnaeus's system of taxonomy and was particularly composed for the "Fair Sex". Twelve volumes were published privately and presented to family, royalty and botanical colleagues across Europe. The "Botanical tables" were illustrated by the renowned botanical artist, John Miller. The illustrations are both aesthetically pleasing and scientifically correct. In this paper we consider the circumstances of the production of the "Botanical tables" and explore how the original sets of this publication and original material have been dispersed.

We aimed to analyze scientific papers published by Turkish authors in "radiology, nuclear medicine and medical imaging" journals included in the Science Citation Index Expanded and compared the number of published scientific papers from Turkey and other countries. We retrospectively searched all papers published by Turkish authors between 1945 and 2008 by using Web of Science software. We performed the analysis by typing "Turkey" in the address section and all radiology and medical imaging journals in the source title section using the general search function of the software. We further analyzed these results by using "analyze" function of the software according to the number of publications per year, journals, institution and type of papers. We also calculated total number of citations to published scientific papers using citation report function. We analyzed the rank of Turkey among other countries in terms of the number of published papers. Overall, 4,532 papers were published between 1945 and 2008. The first paper was published in 1976. Number of publications increased dramatically from 1976 (n = 1) to 2008 (n = 383). The top 5 journals publishing papers from Turkish authors were European Journal of Nuclear Medicine and Molecular Imaging (n = 328), Clinical Nuclear Medicine (n = 296), European Journal of Radiology (n = 289), European Radiology (n = 207) and Journal of Clinical Ultrasound (n = 186). All published papers received 18,419 citations and citation to paper ratio was 4.06. The rank of Turkey among other countries in terms of published papers improved during the last 25 years. Number of papers from Turkey published in radiology and medical imaging journals has increased at the start of the new millennium. Currently, Turkey is among the top 12 countries when the number of scientific papers published in radiology journals is taken into consideration.

Geospatial Health is an international, peer-reviewed scientific journal produced by the Global Network for Geospatial Health (GnosisGIS). This network was founded in 2000 and the inaugural issue of its official journal was published in November 2006 with the aim to cover all aspects of geographical information system (GIS) applications, remote sensing and other spatial analytic tools focusing on human and veterinary health. The University of Naples Federico II is the publisher, producing two issues per year, both as hard copy and an open-access online version. The journal is referenced in major databases, including CABI, ISI Web of Knowledge and PubMed. In 2008, it was assigned its first impact factor (1.47), which has now reached 1.71. Geospatial Health is managed by an editor-in-chief and two associate editors, supported by five regional editors and a 23-member strong editorial board. This overview takes stock of the first five years of publishing: 133 contributions have been published so far, primarily original research (79.7%), followed by reviews (7.5%), announcements (6.0%), editorials and meeting reports (3.0% each) and a preface in the first issue. A content analysis of all the original research articles and reviews reveals that three quarters of the publications focus on human health with the remainder dealing with veterinary health. Two thirds of the papers come from Africa, Asia and Europe with similar numbers of contributions from each continent. Studies of more than 35 different diseases, injuries and risk factors have been presented. Malaria and schistosomiasis were identified as the two most important diseases (11.2% each). Almost half the contributions were based on GIS, one third on spatial analysis, often using advanced Bayesian geostatistics (13.8%), and one quarter on remote sensing. The 120 original research articles, reviews and editorials were produced by 505 authors based at institutions and universities in 52 countries. Importantly, a considerable proportion of the authors come from countries with a low or medium human development index (29.3%). In view of the increasing number of submissions, we are considering to publish more than two issues per year in the future. Finally, our vision is to open-up a new section predominantly based on visual presentations, including brief video clips, as discussed in a symposium at the 60th annual meeting of the American Society of Tropical Medicine and Hygiene in December 2011.

The Danish Medical Association (DMA) performed a survey together with TNS Gallup Denmark among the readers of Ugeskrift for Laeger (Journal of the Danish Medical Association). The main motivation for the questionnaire was to evaluate the acceptability of changing the publication language in original articles from Danish into English. The study was conducted as an on-line questionnaire among the members of the DMA. A systematic sample was drawn from the DMA's member database. The sample comprised a total of 1,970 e-mail addresses. Among these, 1,952 were valid, and 1,952 physicians were invited to participate by e-mail. The response rate (1,046/1,952) was 54%. Among the participants 43% were specialists, 36% were junior doctors and 20% general practitioners. Overall, 45% of the respondents published scientific articles, and particularly specialists and junior doctors did not object to the shift from Danish to English language. Our survey showed that the readers and authors were willing to accept a shift from Danish into English publication language for original research papers.

Carbon dioxide emission factors for U.S. coal by origin and destination

USGS Publications Warehouse

Quick, J.C.

2010-01-01

This paper describes a method that uses published data to calculate locally robust CO2 emission factors for U.S. coal. The method is demonstrated by calculating CO2 emission factors by coal origin (223 counties, in 1999) and destination (479 power plants, in 2005). Locally robust CO2 emission factors should improve the accuracy and verification of greenhouse gas emission measurements from individual coal-fired power plants. Based largely on the county origin, average emission factors for U.S. lignite, subbituminous, bituminous, and anthracite coal produced during 1999 were 92.97,91.97,88.20, and 98.91 kg CO2/GJgross, respectively. However, greater variation is observed within these rank classes than between them, which limits the reliability of CO2 emission factors specified by coal rank. Emission factors calculated by destination (power plant) showed greater variation than those listed in the Emissions & Generation Resource Integrated Database (eGRID), which exhibit an unlikely uniformity that is inconsistent with the natural variation of CO2 emission factors for U.S. coal. ?? 2010 American Chemical Society.

Recent developments in application of stable isotope analysis on agro-product authenticity and traceability.

With the globalisation of agro-product markets and convenient transportation of food across countries and continents, the potential for distribution of mis-labelled products increases accordingly, highlighting the need for measures to identify the origin of food. High quality food with identified geographic origin is a concern not only for consumers, but also for agriculture farmers, retailers and administrative authorities. Currently, stable isotope ratio analysis in combination with other chemical methods gradually becomes a promising approach for agro-product authenticity and traceability. In the last five years, a growing number of research papers have been published on tracing agro-products by stable isotope ratio analysis and techniques combining with other instruments. In these reports, the global variety of stable isotope compositions has been investigated, including light elements such as C, N, H, O and S, and heavy isotopes variation such as Sr and B. Several factors also have been considered, including the latitude, altitude, evaporation and climate conditions. In the present paper, an overview is provided on the authenticity and traceability of the agro-products from both animal and plant sources by stable isotope ratio analysis.

Warp Field Mechanics 101

NASA Technical Reports Server (NTRS)

White, Harold

2011-01-01

This paper will begin with a short review of the Alcubierre warp drive metric and describes how the phenomenon might work based on the original paper. The canonical form of the metric was developed and published in [6] which provided key insight into the field potential and boost for the field which remedied a critical paradox in the original Alcubierre concept of operations. A modified concept of operations based on the canonical form of the metric that remedies the paradox is presented and discussed. The idea of a warp drive in higher dimensional space-time (manifold) will then be briefly considered by comparing the null-like geodesics of the Alcubierre metric to the Chung-Freese metric to illustrate the mathematical role of hyperspace coordinates. The net effect of using a warp drive technology coupled with conventional propulsion systems on an exploration mission will be discussed using the nomenclature of early mission planning. Finally, an overview of the warp field interferometer test bed being implemented in the Advanced Propulsion Physics Laboratory: Eagleworks (APPL:E) at the Johnson Space Center will be detailed. While warp field mechanics has not had a Chicago Pile moment, the tools necessary to detect a modest instance of the phenomenon are near at hand.

Anesthetic Agents of Plant Origin: A Review of Phytochemicals with Anesthetic Activity.

PubMed

Tsuchiya, Hironori

2017-08-18

The majority of currently used anesthetic agents are derived from or associated with natural products, especially plants, as evidenced by cocaine that was isolated from coca ( Erythroxylum coca , Erythroxylaceae) and became a prototype of modern local anesthetics and by thymol and eugenol contained in thyme ( Thymus vulgaris , Lamiaceae) and clove ( Syzygium aromaticum , Myrtaceae), respectively, both of which are structurally and mechanistically similar to intravenous phenolic anesthetics. This paper reviews different classes of phytochemicals with the anesthetic activity and their characteristic molecular structures that could be lead compounds for anesthetics and anesthesia-related drugs. Phytochemicals in research papers published between 1996 and 2016 were retrieved from the point of view of well-known modes of anesthetic action, that is, the mechanistic interactions with Na⁺ channels, γ-aminobutyric acid type A receptors, N -methyl-d-aspartate receptors and lipid membranes. The searched phytochemicals include terpenoids, alkaloids and flavonoids because they have been frequently reported to possess local anesthetic, general anesthetic, antinociceptive, analgesic or sedative property. Clinical applicability of phytochemicals to local and general anesthesia is discussed by referring to animal in vivo experiments and human pre-clinical trials. This review will give structural suggestions for novel anesthetic agents of plant origin.

Journals in this category of the Science Citation Index Expanded were included in the study. Scientific papers were retrieved from the Web of Science online database. Quality was measured according to impact factor, citation of articles, number of articles published in top 10 journals, and the 10 most popular journals by country (area). In the field of health care sciences and services, the annual incremental rates of scientific articles published from 2007 to 2014 were higher than rates of published scientific articles in all fields. Researchers from the Chinese mainland published the most original articles and reviews and had the highest accumulated impact factors, highest total article citations, and highest average citation. Publications from India had the highest average impact factor. In the field of health care sciences and services, China has made remarkable progress during the past eight years in the annual number and percentage of scientific publications. Yet, there is room for improvement in the quantity and quality of such articles. PMID:26712774

An historical look at the Binghamton Geomorphology Symposium

Sawyer, Carol F.; Butler, David R.; O'Rourke, Tela

2014-10-01

The Binghamton Geomorphology Symposium (BGS) is an annual meeting held since 1970, usually in the U.S.A., on timely topics in the field of geomorphology. A special issue of this journal presents the papers from each meeting and provides an opportunity to disseminate to the international community research relevant to that year's theme written by key people in that field. In this paper, we review the history of the BGS, examine the academic disciplines of each year's organizers, compile a list of the researchers who have made multiple contributions to BGS, note the citation impact of papers published in the annual proceedings, map the spatial distribution of the meeting locations, and categorize the gender distribution of the contributors to the symposium. Contributions from female authors to the BGS have steadily increased since the 1970s; however, from 2003 to 2013, females still only accounted for 23.6% of the proceeding's papers, an increase of 16.4% from the 1970s. These numbers are not surprising when compared to the gender distribution of the top positions in specialty groups in the U.S. Between 1989 and 2010, over 7000 citations were from articles published in BGS special issues, indicating their contributions to the geomorphology field. When normalized by the number of years the articles have been available, papers from BGS whose themes combined geomorphology with other fields (i.e., natural hazards and geomorphology), rated higher numbers of citations. The dispersion of the location of BGS meetings illustrates how the series is maturing by moving away from its origin in the U.S. northeast.

Defining and identifying Sleeping Beauties in science

PubMed Central

Ke, Qing; Ferrara, Emilio; Radicchi, Filippo; Flammini, Alessandro

2015-01-01

A Sleeping Beauty (SB) in science refers to a paper whose importance is not recognized for several years after publication. Its citation history exhibits a long hibernation period followed by a sudden spike of popularity. Previous studies suggest a relative scarcity of SBs. The reliability of this conclusion is, however, heavily dependent on identification methods based on arbitrary threshold parameters for sleeping time and number of citations, applied to small or monodisciplinary bibliographic datasets. Here we present a systematic, large-scale, and multidisciplinary analysis of the SB phenomenon in science. We introduce a parameter-free measure that quantifies the extent to which a specific paper can be considered an SB. We apply our method to 22 million scientific papers published in all disciplines of natural and social sciences over a time span longer than a century. Our results reveal that the SB phenomenon is not exceptional. There is a continuous spectrum of delayed recognition where both the hibernation period and the awakening intensity are taken into account. Although many cases of SBs can be identified by looking at monodisciplinary bibliographic data, the SB phenomenon becomes much more apparent with the analysis of multidisciplinary datasets, where we can observe many examples of papers achieving delayed yet exceptional importance in disciplines different from those where they were originally published. Our analysis emphasizes a complex feature of citation dynamics that so far has received little attention, and also provides empirical evidence against the use of short-term citation metrics in the quantification of scientific impact.

It is instructive to take stock of this output to determine patterns of interest and where the cutting edge lies. We have surveyed the field of allergic disease as seen through the pages of Clinical and Experimental Allergy (CEA) highlighting trends, emphasizing notable observations and placing discoveries in the context of other key papers published during the year. The review is divided into similar sections as the journal. In the field of Asthma and Rhinitis CEA has contributed significantly to the debate about asthma phenotypes and expressed opinions about the cause of intrinsic asthma. It has also added its halfpennyworth to the hunt for meaningful biomarkers. In Mechanisms the considerable interest in T cell subsets including Th17 and T regulatory cells continues apace and the discipline of Epidemiology continues to invoke a steady stream of papers on risk factors for asthma with investigators still trying to explain the post-second world war epidemic of allergic disease. Experimental Models continue to make important contributions to our understanding of pathogenesis of allergic disease and in the Clinical Allergy section various angles on immunotherapy are explored. New allergens continue to be described in the allergens section to make those allergen chips even more complicated. A rich and vibrant year helpfully summarized by some of our associate editors.

Forensic science is a multidisciplinary field, which covers many branches of the pure, the applied and the biomedical sciences. Writing-up and publishing research findings helps to enhance the reputation of the investigators and the laboratories where the work was done. The number of times an article is cited in the reference lists of other articles is generally accepted as a mark of distinction. Indeed, citation analysis has become widely used in research assessment of individual scientists, university departments and entire nations. This article concerns the most highly cited papers published in the Journal of Forensic Sciences (JFS) between 1956 and 2005. These were identified with the help of Web-of-Science, which is the on-line version of Science Citation Index, produced by Thomson Institute for Scientific Information (Thomson ISI) with head offices in Philadelphia, USA. This database tracks, among other things, the annual citation records of articles published in several thousand scientific journals worldwide. Those JFS articles accumulating 50 or more citations were identified and rank-ordered according to the total number of citations. These articles were also evaluated according to the name of first author, the subject category of the article, the country of origin and the pattern of co-authorship. This search strategy located 46 articles cited between 50 and 292 times since they first appeared in print. The most highly cited paper by far was by Kasai, Nakamura and White (USA and Japan) concerning DNA profiling and the application of the polymerase chain reaction (PCR) in forensic science. Some forensic scientists appeared as first author on two to three highly cited articles, namely Wetli (USA), Budowle (USA) and Comey (USA). When the highly cited articles were sub-divided into subject category, 15 were identified as coming from toxicology, closely followed by criminalistics (14 articles), pathology (nine articles), physical anthropology (five articles), forensic psychiatry (two articles) and one from odontology. The number of co-authors on these highly cited articles ranged from one to nine and the names of some investigators appeared on as many as four highly cited papers. The vast majority of papers originated from US laboratories although five came from Japan, two each from Sweden and Canada and there was also a joint USA-Swiss collaboration. The Thompson ISI citation databases provide unique tools for tracking citations to individual articles and impact and citation records of scholarly journals.

Objective The objective of this study was to examine the type and content of Journal of Women’s Health Physical Therapy (JWHPT) publications over the last decade. Study Design Content and bibliometric analysis of published literature Background Component sections, such as the Section on Women’s Health (SoWH) of the American Physical Therapy Association provide content expertise to areas of specialty physical therapist practice, thereby supporting the dissemination of evidence for physical therapists to use. Closely aligned with the mission of the SoWH, JWHPT provides evidence reflecting this practice area. The purpose of our analysis was to examine publications within JWHPT to determine how closely JWHPT is meeting the mission and focus of section members. Methods and Measures We used established bibliographic methodology to code and review manuscripts published online between 2005 and 2015 in JWHPT using established domains (article type, participant type, research design, study purpose, and area of focus). Total publications and proportion of publications based on domain were described. Impact by citation and author was examined using bibliometric software. Results Eighteen percent of the items published in JWHPT were original research papers submitted for the first time. Of those papers, the primary study design was cross-sectional experimental research, most commonly studying interventions. The primary practice area reported was management of incontinence. Conclusions We suggest that a continued need to increase efforts for the submission and publication of a greater proportion of randomized controlled trials and metric articles. PMID:29375281

Citing a Data Repository: A Case Study of the Protein Data Bank

The Protein Data Bank (PDB) is the worldwide repository of 3D structures of proteins, nucleic acids and complex assemblies. The PDB’s large corpus of data (> 100,000 structures) and related citations provide a well-organized and extensive test set for developing and understanding data citation and access metrics. In this paper, we present a systematic investigation of how authors cite PDB as a data repository. We describe a novel metric based on information cascade constructed by exploring the citation network to measure influence between competing works and apply that to analyze different data citation practices to PDB. Based on this new metric, we found that the original publication of RCSB PDB in the year 2000 continues to attract most citations though many follow-up updates were published. None of these follow-up publications by members of the wwPDB organization can compete with the original publication in terms of citations and influence. Meanwhile, authors increasingly choose to use URLs of PDB in the text instead of citing PDB papers, leading to disruption of the growth of the literature citations. A comparison of data usage statistics and paper citations shows that PDB Web access is highly correlated with URL mentions in the text. The results reveal the trend of how authors cite a biomedical data repository and may provide useful insight of how to measure the impact of a data repository. PMID:26317409

Cometary Origin of Atmospheric Methane Variations on Mars Unlikely

2016-01-01

The detection of methane in the atmosphere of Mars was first reported in 2004. Since then a number of independent observations of methane have been reported, all showing temporal variability. Up until recently, the origin of methane was attributed to sources either indigenous to Mars or exogenous, where methane is a UV degradation byproduct of organics falling on to the surface. Most recently, a new hypothesis has been proposed that argues that the appearance and variation of methane are correlated with specific meteor events at Mars. Indeed, extraplanetary material can be brought to a planet when it passes through a meteoroid stream left behind by cometary bodies orbiting the Sun. This occurs repeatedly at specific times in a planet's year as streams tend to be fairly stable in space. In this paper, we revisit this latest hypothesis by carrying out a complete analysis of all available data on Mars atmospheric methane, including the very recent data not previously published, together with all published predicted meteor events for Mars. Whether we consider the collection of individual data points and predicted meteor events, whether we apply statistical analysis, or whether we consider different time spans between high methane measurements and the occurrence of meteor events, we find no compelling evidence for any correlation between atmospheric methane and predicted meteor events.

Influence of the Casserius Tables on fetal anatomy illustration and how we envision the unborn*

Objective: The paper demonstrates how visual representation of the fetus in early anatomy texts influenced the reader's perception of the unborn child as an autonomous being. Data Sources: The health, art, and history literatures were used as sources. Original texts and illustrations, with particular attention paid to the Casserius Tables, published by Andreas Spigelius in 1627, are discussed. Study Selection: A review of the literature was conducted to identify and analyze published renderings, reproductions, and discussion of images of the unborn child. Original anatomy atlases were consulted. Main Results: Artists' renderings of a particularly vulnerable state of human life influenced early perceptions of the status of the unborn child. The images show fetuses as highly independent, providing a visual cue that life is fully formed in utero. Conclusion: The legacy of the Casserius Tables is that they are still able to capture our attention because they portray the idea of a fetus and newborn even more clearly than our modern representations of this charged topic. The use of deceptive realism provides the viewer with an accessible visual representation of the unborn child. These early anatomy illustrations continue to influence modern-day perception of the unborn child as a separate being, completely autonomous from the mother. PMID:21243052

If you downloaded the original PDF but are unable to access the revision, please contact SPIE Digital Library Customer Service for assistance. The Payload Technology Validation Section (SRE-FV) at ESTEC has the goal to validate new technology for future or on-going mission. In this framework, a test set up to characterize the quantum efficiency of near-infrared (NIR) detectors has been created. In the context of the NIR European Large Format Array ("LFA"), 3 deliverables detectors coming from SELEX-UK/ATC (UK) on one side, and CEA/LETI- CEA/IRFU-SOFRADIR (FR) on the other side were characterized. The quantum efficiency of an HAWAII-2RG detector from Teledyne was as well measured. The capability to compare on the same setup detectors from different manufacturers is a unique asset for the future mission preparation office. This publication will present the quantum efficiency results of a HAWAII-2RG detector from Teledyne with a 2.5um cut off compared to the LFA European detectors prototypes developed independently by SELEX-UK/ATC (UK) on one side, and CEA/LETI- CEA/IRFU-SOFRADIR (FR) on the other side.

[Trisomy 21 in visual art].

Stahl, A; Tourame, P

In 1866, J. Langdon Down published a paper on "an ethnic classification of idiots" and noted their facial resemblance with individuals of the Mongolian people. In 1959, J. Lejeune, M. Gautier, and R. Turpin demonstrated that the children with Down syndrome had an extra copy of chromosome 21. There is now a debate within the medical literature on the age of trisomy 21 as a disease affecting mankind. Since it was not described before 1866, some authors questioned whether this disease is an old or new condition in humans. Three methods of investigation are useful for demonstrating that trisomy 21 has been present in humans for a long time: the figuration of this condition in historical paintings, figurines, and pottery; its presence in old skeletal remains; and the origin of human chromosome 21 during primate phylogeny. Figurines strongly suggestive of trisomy 21 have been found in the Greco-Roman world, in many Central and South American pre-Columbian cultures, and in Khmer temples. In Europe, during the Renaissance, Italian and Flemish artists represented trisomy 21 in paintings of religious inspiration. Studies on the origin and pathology of chromosome 21 have shown that the ancestral human chromosome 21 arose 30-50 million years ago and that trisomy 21 has existed since time immemorial.

Use of bipolar radiofrequency catheter ablation in treatment of cardiac arrhythmias.

Soucek, Filip; Starek, Zdenek

2018-05-23

Background Arrhythmia management is a complex process involving both pharmacological and non-pharmacological approaches. Radiofrequency ablation is the pillar of non-pharmacological arrhythmia treatment. Unipolar ablation is considered to be the gold standard in the treatment of the majority of arrhythmias; however, its efficacy is limited to specific cases. In particular, the creation of deep or transmural lesions to eliminate intramurally originating arrhythmias remains inadequate. Bipolar ablation is proposed as an alternative to overcome unipolar ablation boundaries. Results Despite promising results gained from in vitro and animal studies showing that bipolar ablation is superior in creating transmural lesions, the use of bipolar ablation in daily clinical practice is limited. Several studies have been published showing that bipolar ablation is effective in the treatment of clinical arrhythmias after failed unipolar ablation, however there is inconsistency regarding safety of bipolar ablation within the available research papers. According to research evidence the most common indications for bipolar ablation use are ventricular originating rhythmic disorders in patients with structural heart disease resistant to standard radiofrequency ablation. Conclusions To allow wider clinical application the efficiency and safety of bipolar ablation need to be verified in future studies.

Definition of chronic kidney disease and measurement of kidney function in original research papers: a review of the literature.

Anderson, Jocelyn; Glynn, Liam G

2011-09-01

Over the past decade, chronic kidney disease (CKD) has become an area of intensive clinical and epidemiological research. Despite the clarity provided by the Kidney Disease Outcomes Quality Initiative (KDOQI) guidelines, there appears to be within the CKD research literature significant disagreement on how to define CKD and measure kidney function. The objectives of this study were to investigate the variety of methods used to define CKD and to measure kidney function in original research papers as well as to investigate whether the quality of the journal had any effect on the quality of the methodology used. This was a descriptive review and not a meta-analysis. Information was extracted from each article including publication details (including the journal's impact factor), definition of CKD, method used to estimate kidney function and quantity of serum creatinine readings used to define CKD. An electronic search of MEDLINE through OVID was completed using the search term CKD. The search was limited to articles in English published in 2009. Studies were included in the review only if they were original research articles including patients with CKD. Articles were excluded if they reported data from a paediatric population, a population solely on dialysis or if there was no full-text access through OVID. Each article was assessed for quality with respect to using KDOQI CKD definition criteria. A description of the pooled data was completed and chi-square tests were used to investigate the relation between article quality and journal quality. Analysis was carried out using SPSS (15.0) and a P-value of <0.05 was considered to indicate statistical significance. The final review included 301 articles. There were a variety of methods used to define CKD in original research articles. Less than 20% (n = 59) of the articles adhered to the established international criteria for defining CKD. The majority of articles (52.1%) did not indicate the quantity of serum creatinine measurements used to define CKD. The impact factor or specialist nature of the scientific journal appears to have no bearing on whether or not published articles use the gold standard KDOQI guidelines for labelling a patient with a diagnosis of CKD. This review of literature found that a variety of definitions are being used in original research articles to define CKD and measure kidney function which calls into question the validity and reliability of such research findings and associated clinical guidelines. International consensus is urgently required to improve validity and generalizability of CKD research findings.

[Purpose] The purpose of this study was to investigate the degree of collaboration between practitioners and researchers through research papers related to the implementation of electrical stimulation (ES) for stroke patients. [Methods] A systematic review of the literature was conducted to collect data from ES studies published before January 7, 2015. Five databases were searched for search terms related to stroke and ES. Inclusion criteria were original papers that reported on ES of the upper or lower limbs following stroke, after the exclusion of case reports, brain stimulation studies, and papers written in any languages other than English or Japanese. The outcome was the prevalence of research papers that included a practitioner as an author, that included a practitioner as an author or in the acknowledgements, and in which the practitioner was the first author. [Results] Based on the selection criteria, 165 papers were included in the final analysis. The prevalence of papers in which a practitioner was included as an author was 39%. The prevalence of papers in which a practitioner was included as an author or in the acknowledgements was 50%. A practitioner was the first author of 34% of the papers. [Conclusion] Collaboration on research papers related to ES for stroke patients is limited.

Proteomics of Plant Pathogenic Fungi

Plant pathogenic fungi cause important yield losses in crops. In order to develop efficient and environmental friendly crop protection strategies, molecular studies of the fungal biological cycle, virulence factors, and interaction with its host are necessary. For that reason, several approaches have been performed using both classical genetic, cell biology, and biochemistry and the modern, holistic, and high-throughput, omic techniques. This work briefly overviews the tools available for studying Plant Pathogenic Fungi and is amply focused on MS-based Proteomics analysis, based on original papers published up to December 2009. At a methodological level, different steps in a proteomic workflow experiment are discussed. Separate sections are devoted to fungal descriptive (intracellular, subcellular, extracellular) and differential expression proteomics and interactomics. From the work published we can conclude that Proteomics, in combination with other techniques, constitutes a powerful tool for providing important information about pathogenicity and virulence factors, thus opening up new possibilities for crop disease diagnosis and crop protection.

Scientists who are members of an editorial board have been accused of preferentially publishing their scientific work in the journal where they serve as editor. Reputation and academic standing do depend on an uninterrupted flow of published scientific work and the question does arise as to whether publication mainly occurs in the self-edited journal. This investigation was designed to determine whether editorial board members of five urological journals were more likely to publish their research reports in their own rather than in other journals. A retrospective analysis was conducted for all original reports published from 2001–2010 by 65 editorial board members nominated to the boards of five impact leading urologic journals in 2006. Publications before editorial board membership, 2001–2005, and publications within the period of time as an editorial board member, 2006–2010, were identified. The impact factors of the journals were also recorded over the time period 2001–2010 to see whether a change in impact factor correlated with publication locality. In the five journals as a whole, scientific work was not preferentially published in the journal in which the scientists served as editor. However, significant heterogeneity among the journals was evident. One journal showed a significant increase in the amount of published papers in the ‘own’ journal after assumption of editorship, three journals showed no change and one journal showed a highly significant decrease in publishing in the ‘own’ journal after assumption of editorship.

Even though citation analysis has several limitations, it is a commonly used tool to determine the impact of scientific articles in different research fields. The study aims to identify and systematically review the 100 most cited articles in the field of visceral surgery focusing on papers that modified therapeutic concepts and influenced the surgeons' decision making. The 100 most cited clinical articles in visceral surgery were identified using Journal Citation Reports and Science Citation Index Expanded of the Web of Science (Thomson Reuters, Philadelphia, Pa., USA). Data for characterization of the articles were determined: Number of citations, research topic, journal, publication time, authorship, country of origin, type of article and level of evidence if reasonable. The 100 most cited articles were published in 17 journals; 72 articles were found in the 3 journals: New England Journal of Medicine (38), Annals of Surgery (21) and Lancet (13). The oldest article was published in 1908 in Annals of Surgery (ranked 76th) and the most recent in 2012 in Lancet (65th). Eighty articles were published between 1990 and 2010. The number of citations ranged from 667 to 4,666 (median 925). The leading country of origin was the United States with 39 articles, followed by articles originating from more than one country (30). There were 45 interventional studies (27 randomized controlled trials), 32 observational studies, 19 reviews and 4 guidelines, definitions or classifications. The level of evidence was low (IV) in 42 articles and high in 35 articles (Ia or Ib). A high number of citations did not reflect a high level of evidence. The topics and research questions of the identified articles covered a large area of visceral surgery. Some of the milestones in visceral surgery were identified. The high impact measured by citations did not reflect a high quality of research (level of evidence) in a considerable number of publications. © 2016 S. Karger AG, Basel.

Taxonomic descriptions are traditionally composed in natural language and published in a format that cannot be directly used by computers. The Exploring Taxon Concepts (ETC) project has been developing a set of web-based software tools that convert morphological descriptions published in telegraphic style to character data that can be reused and repurposed. This paper introduces the first semi-automated pipeline, to our knowledge, that converts morphological descriptions into taxon-character matrices to support systematics and evolutionary biology research. We then demonstrate and evaluate the use of the ETC Input Creation - Text Capture - Matrix Generation pipeline to generate body part measurement matrices from a set of 188 spider morphological descriptions and report the findings. From the given set of spider taxonomic publications, two versions of input (original and normalized) were generated and used by the ETC Text Capture and ETC Matrix Generation tools. The tools produced two corresponding spider body part measurement matrices, and the matrix from the normalized input was found to be much more similar to a gold standard matrix hand-curated by the scientist co-authors. Special conventions utilized in the original descriptions (e.g., the omission of measurement units) were attributed to the lower performance of using the original input. The results show that simple normalization of the description text greatly increased the quality of the machine-generated matrix and reduced edit effort. The machine-generated matrix also helped identify issues in the gold standard matrix. ETC Text Capture and ETC Matrix Generation are low-barrier and effective tools for extracting measurement values from spider taxonomic descriptions and are more effective when the descriptions are self-contained. Special conventions that make the description text less self-contained challenge automated extraction of data from biodiversity descriptions and hinder the automated reuse of the published knowledge. The tools will be updated to support new requirements revealed in this case study.

LETTERA DEL DIRETTORE.

Picardi, Nicola

2016-01-01

In nearly three decades to the direction of the journal Annali Italiani di Chirurgia I could add to my personal experiences as surgeon and University Professor of Surgery, those very special in the rather different field of scientific literature from the specific point of view of Chief Editor - English term that identifies the "Director" of a scientific journal. The original wish to enhance and promote the qualities of researches and professional activity of Italian surgery within the journal, after an initial phase of normal management has expanded ambitiously, and over the last decade has been taken new editorial strategic decisions to promote more and more the cultural value and the diffusion of the magazine, for the benefit of its subscribers and its readers. Therefore, since 2007 the preferential adoption of English was introduced, then it became the exclusive language from 2010. Later in 2008 there was the authoritative introduction of the magazine in the "informatics network" with the activation of a "web site" to constitute the parallel Digital Edition of Annali Italiani di Chirurgia, ISSN credited with the CNR, to constitute a large interactive library where there are nowadays collected in free reading all articles published in press from 2000 up to those published in the first half of 2015 - with subsequent to follow. In parallel it was inaugurated the section reserved to the individual "Clinical cases", published exclusively online in the same Digital Edition, with preservation of iconography colors. The own search motor of the "site" (www.annitalchir.com) enables the identification of all articles published in the Digital Edition, whether published in print or exclusively online, proceeding by title, by author, by keyword, and of course by date of publication. The functionality of the purchase mechanism of each article with the procedure of "e-commerce" right from the site and the possibility for all readers to interactively express the own evaluation of published articles, has transformed the site into a "portal" constantly updated, and this has led to the growing number of foreign authors asking access with their papers to the magazine, especially from the Mediterranean area and Eastern Europe. Considering the variety and quality of the studies performed not only in Italy but also in such a vast geographical and cultural area, evident in the articles already published, it seems appropriate not only the substantial analysis by the Scientific Committee of the articles received to be published, but also to underline the care of the formal aspects of those proposed to the press, and to express a series of suggestions, to urge the Authors to improve the formal aspects in the preparation and exposure for their articles, to benefit of their image of Authors and for prestige of the magazine in an international perspective. This is the meaning of the Leading Article of this first issue 2016. I conclude by listing the qualitative preferences adopted for accepting articles to be published, provided that the individual clinical cases - the surgical "chronicle" - have a privileged place in the Digital Edition of Annali Italiani di Chirurgia, preserving the colors of the iconography, but that only exceptionally will be published in the printed issues. IDEAL TYPES OF PAPER to be submitted for publication in Annali Italiani di Chirurgia 1. Results of original research on a topical issue; 2. Update on a theme with contributions of personal experiences; 3. Analysis of personal case histories of prospective studies; 4. Evaluation of case studies personal accompanied by extensive and comprehensive bibliographic revisions; 5. setups on the individual, with the formulation of opinions by the Authors; 6. Proposals for new surgical techniques; 7. Technological innovations; ACCEPTABLE TYPES OF PAPER to be submitted for publication in the Annals of Surgery Italian a) Editorial updating or development to the work of a single author; b) Description of unusual clinical cases (exclusively for online e-publish in www.annitalchir.com); c) Reviews of multicenter studies.

Background Electronic health (eHealth) and mobile health (mHealth) approaches to address low physical activity levels, sedentary behavior, and unhealthy diets have received significant research attention. However, attempts to systematically map the entirety of the research field are lacking. This gap can be filled with a bibliometric study, where publication-specific data such as citations, journals, authors, and keywords are used to provide a systematic overview of a specific field. Such analyses will help researchers better position their work. Objective The objective of this review was to use bibliometric data to provide an overview of the eHealth and mHealth research field related to physical activity, sedentary behavior, and diet. Methods The Web of Science (WoS) Core Collection was searched to retrieve all existing and highly cited (as defined by WoS) physical activity, sedentary behavior, and diet related eHealth and mHealth research papers published in English between January 1, 2000 and December 31, 2016. Retrieved titles were screened for eligibility, using the abstract and full-text where needed. We described publication trends over time, which included journals, authors, and countries of eligible papers, as well as their keywords and subject categories. Citations of eligible papers were compared with those expected based on published data. Additionally, we described highly-cited papers of the field (ie, top ranked 1%). Results The search identified 4805 hits, of which 1712 (including 42 highly-cited papers) were included in the analyses. Publication output increased on an average of 26% per year since 2000, with 49.00% (839/1712) of papers being published between 2014 and 2016. Overall and throughout the years, eHealth and mHealth papers related to physical activity, sedentary behavior, and diet received more citations than expected compared with papers in the same WoS subject categories. The Journal of Medical Internet Research published most papers in the field (9.58%, 164/1712). Most papers originated from high-income countries (96.90%, 1659/1717), in particular the United States (48.83%, 836/1712). Most papers were trials and studied physical activity. Beginning in 2013, research on Generation 2 technologies (eg, smartphones, wearables) sharply increased, while research on Generation 1 (eg, text messages) technologies increased at a reduced pace. Reviews accounted for 20 of the 42 highly-cited papers (n=19 systematic reviews). Social media, smartphone apps, and wearable activity trackers used to encourage physical activity, less sedentary behavior, and/or healthy eating were the focus of 14 highly-cited papers. Conclusions This study highlighted the rapid growth of the eHealth and mHealth physical activity, sedentary behavior, and diet research field, emphasized the sizeable contribution of research from high-income countries, and pointed to the increased research interest in Generation 2 technologies. It is expected that the field will grow and diversify further and that reviews and research on most recent technologies will continue to strongly impact the field. PMID:29669703

Open access is not only a form of publishing such that research papers become available to the large public free of charge, it also refers to a trend in science that the act of doing research becomes more open and transparent. When science transforms to open access we not only mean access to papers, research data being collected, or data being generated, but also access to the data used and the procedures carried out in the research paper. Increasingly, scientific results are generated by numerical manipulation of data that were already collected, and may involve simulation experiments that are completely carried out computationally. Reproducibility of research findings, the ability to repeat experimental procedures and confirm previously found results, is at the heart of the scientific method (Pebesma, Nüst and Bivand, 2012). As opposed to the collection of experimental data in labs or nature, computational experiments lend themselves very well for reproduction. Some of the reasons why scientists do not publish data and computational procedures that allow reproduction will be hard to change, e.g. privacy concerns in the data, fear for embarrassment or of losing a competitive advantage. Others reasons however involve technical aspects, and include the lack of standard procedures to publish such information and the lack of benefits after publishing them. We aim to resolve these two technical aspects. We propose a system that supports the evolution of scientific publications from static papers into dynamic, executable research documents. The DFG-funded experimental project Opening Reproducible Research (ORR) aims for the main aspects of open access, by improving the exchange of, by facilitating productive access to, and by simplifying reuse of research results that are published over the Internet. Central to the project is a new form for creating and providing research results, the executable research compendium (ERC), which not only enables third parties to reproduce the original research and hence recreate the original research results (figures, tables), but also facilitates interaction with them as well as their recombination with new data or methods. Building on existing open standards and software, this project develops standards and tools for ERCs, and will demonstrate and evaluate these, focusing on the geosciences domains. The project goes beyond a technical solution for ERCs by evaluating the system from the perspectives of geoscience researchers as participants in a scientific publication process. It will focus on the statistical environment R, but also evaluate larger run time systems captured in virtual environments (Docker containers). ERCs are built upon and integrate well with both established day-to-day workflows of digital research and the scientific publication process. They make research accessible on different levels at any stage to anyone via open web platforms. Other scientists can transfer a compendium of software and tools to their own local environment and collaborate, while others make minimal changes and compare changed results in a web browser. Building on recent advances in mainstream IT, ORR envisions a new architecture for storing, executing and interacting with the original analysis environment alongside the corresponding research data and text. ORR bridges the gap between long-term archives, practical geoscience researchers, as well as publication media. Consequently, the project team seeks input and feedback from researchers working with geospatial data to ensure usable and useful open access publications as well as a publication process that minimizes effort while maximizing usability and re-usability. {References} Pebesma, E., D.

2016-06-01

Variety of problems in science and engineering may be described by fractional partial differential equations (FPDE) in relation to space and/or time fractional derivatives. The difference between time fractional diffusion equations and standard diffusion equations lies primarily in the time derivative. Over the last few years, iterative schemes derived from the rotated finite difference approximation have been proven to work well in solving standard diffusion equations. However, its application on time fractional diffusion counterpart is still yet to be investigated. In this paper, we will present a preliminary study on the formulation and analysis of new explicit group iterative methods in solving a two-dimensional time fractional diffusion equation. These methods were derived from the standard and rotated Crank-Nicolson difference approximation formula. Several numerical experiments were conducted to show the efficiency of the developed schemes in terms of CPU time and iteration number. At the request of all authors of the paper an updated version of this article was published on 7 July 2016. The original version supplied to AIP Publishing contained an error in Table 1 and References 15 and 16 were incomplete. These errors have been corrected in the updated and republished article.

Traditional science lectures and labs are often enhanced through project- and team-based learning. Some students go beyond these classroom studies by conducting research, often under the guidance of university professors. A one-semester astronomy research seminar was initiated in 2006 in collaboration with the community of professional and amateur double star astronomers. The result was dozens of jointly-authored papers published in the Journal of Double Star Observations and the Annual Proceedings of the Society of Astronomical Sciences. This seminar, and its affiliated community, launched a series of conferences and books, providing students with additional forums to share their double star research. The original seminar, and its derivatives, enhanced educational careers through college admissions and scholarships. To expand the seminar's reach, it was restructured from a few teams at one school, to many teams, each from a different school. A volunteer from each school became an assistant instructor. Most of them were seminar veterans, experienced astronomers, or science teachers. The assistant instructors, in turn, recruited enthusiastic students for their teams. To avoid student and instructor overload, the seminar focused on its three deliverables: a formal proposal, published paper, and public PowerPoint presentation. Future seminars may offer other astronomical research options such as exoplanet transit or eclipsing binary photometry.

The purpose of this paper was to describe patterns of superficial reflux in the groin with respect to the terminal valve (TV), which is located at the saphenous opening to the common femoral vein, the great saphenous vein, and its tributary veins. This study included 2019 legs with chronic venous insufficiency that received endoluminal varicose vein treatment because of varicosities with insufficiency of the saphenofemoral junction (SFJ). In a preoperative duplex ultrasound investigation of the superficial vein system, reflux after provocation in the SFJ, great saphenous vein, cranial veins (superficial external pudendal vein, superficial epigastric vein, superficial circumflex iliac vein), and anterior and posterior accessory saphenous veins was recorded and classified on the basis of the origin of reflux. In 1348 legs (66.8%), the reflux had its origin exclusively in the common femoral vein. In 170 legs (8.4%), the reflux had its origin in the common femoral and cranial veins. In 430 legs (21.3%), the insufficiency was due to saphenocranial reflux only. In 71 legs (3.5%), the origin of reflux could not be determined. Reflux in the SFJ does not involve the TV in 24.8% of the legs, implying that routine high ligation and ablation close to the TV might be overtreatment in these patients.

Trends in the field of fluvial geomorphology have been reviewed by a number of authors, who have emphasized the dramatic change occuring in the field in the last two decades of the twentieth century, largely as a result of technological advances. Nevertheless, no prior authors have systematically compiled data on publications in fluvial geomorphology over a long period and statistically analyzed the resulting data set. In this contribution we present a quantitative analysis of fluvial geomorphology papers published in the twenty-two-year period 1987–2009 in five journals of the discipline with a more specific focus on Geomorphology and Earth Surface Processes and Landforms (ESPL), identifying authorships, geographic origin of authors, and spatial and temporal scales covered. We also documented the tools employed, demonstrating the transformation of the field with the emergence of new tools over this period, and conducted a cluster to highlight links between tools and a set of factors (country of author's origin, journals, time, and spatial and temporal scales). Of the 1717 papers published in the five journals during this period, the results showed an increased diversity in the nationality of the first author, mainly when dealing with present time scale, and channel feature. Our data show a significant change in methods used in the field as a result of the increase in data availability and new sources of information from remote sensing (ground, airborne and, satellite). Clearly, a new era in knowledge production is observed since 2000, showing the emergence of a second period of active quantification and an internationalization of the fields.

We aimed to examine the impact and quality of the research presented in the Israel Society of Rheumatology (ISR) annual scientific meetings by measuring publication rates of the abstracts in peer-reviewed journals and investigating the factors that influenced publication. We examined the outcome of all 79 abstracts submitted to the ISR for the 1998-2000 annual meetings. A MEDLINE search of all abstracts, by authors, topics and keywords was performed. Senior authors of abstracts not found to be published in this search were interviewed regarding publication and factors influencing submission. We described the effect of variable factors on the rate of publication. As of September 2002, 63 (80%) abstracts were published in peer-reviewed journals or are currently in-press. Most abstracts were published in prominent journals (with a high impact factor). The majority of the abstracts (61%) were published in rheumatologic journals, 65% of the studies originated from tertiary centers and 19% of the studies were multicenter. The most common diseases studied were antiphospholipid syndrome (20%), systemic lupus erythematosus (19%) and inflammatory arthritis (18%). Most of the studies were of disease pathogenesis (35%) and clinical manifestations (33%). The most common study designs were basic science (34%). An overall 57% of the studies reported "positive" results and 9% reported "negative" results. None of the factors studied were associated with publication or non-publication. The main cause cited by authors for not publishing their abstract was lack of time to prepare a full paper or a desire to further expand the study. Within this group of 16 authors of abstracts, 11 authors still plan to submit a paper. The ISR annual meetings have an important clinical scientific impact as measured by the high rate of abstracts published as full length articles in leading peer-reviewed journals.

An automatically updateable web publishing solution: taking document sharing and conversion to enterprise level

Rahman, Fuad; Tarnikova, Yuliya; Hartono, Rachmat; Alam, Hassan

2006-01-01

This paper presents a novel automatic web publishing solution, Pageview (R). PageView (R) is a complete working solution for document processing and management. The principal aim of this tool is to allow workgroups to share, access and publish documents on-line on a regular basis. For example, assuming that a person is working on some documents. The user will, in some fashion, organize his work either in his own local directory or in a shared network drive. Now extend that concept to a workgroup. Within a workgroup, some users are working together on some documents, and they are saving them in a directory structure somewhere on a document repository. The next stage of this reasoning is that a workgroup is working on some documents, and they want to publish them routinely on-line. Now it may happen that they are using different editing tools, different software, and different graphics tools. The resultant documents may be in PDF, Microsoft Office (R), HTML, or Word Perfect format, just to name a few. In general, this process needs the documents to be processed in a fashion so that they are in the HTML format, and then a web designer needs to work on that collection to make them available on-line. PageView (R) takes care of this whole process automatically, making the document workflow clean and easy to follow. PageView (R) Server publishes documents, complete with the directory structure, for online use. The documents are automatically converted to HTML and PDF so that users can view the content without downloading the original files, or having to download browser plug-ins. Once published, other users can access the documents as if they are accessing them from their local folders. The paper will describe the complete working system and will discuss possible applications within the document management research.

Dhat syndrome: a systematic review.

Udina, Marc; Foulon, Hubert; Valdés, Manuel; Bhattacharyya, Sagnik; Martín-Santos, Rocío

2013-01-01

Dhat syndrome is a widely recognized clinical condition often seen on the Indian subcontinent that is characterized by a preoccupation with semen loss in urine and other symptoms such as fatigue or depressed mood. Although it has been considered to be a culture-bound syndrome, it may also be regarded as a distinct manifestation of depression or another medical illness. The purpose of this paper was to carry out a systematic review on Dhat syndrome. A review of the literature published up until February 2012 was conducted using the key words [Dhat syndrome] or [semen-loss anxiety] or [semen-loss syndrome]. We included only original studies. The majority of studies reported patients from the Indian subcontinent. There was a high degree of heterogeneity among the studies. Dhat was a common condition in young people from certain cultures and origins. Depressive and anxiety symptoms were common, including fatigue, sleepiness, and sexual dysfunction. Good clinical engagement, social support, and sexual education were useful in some cases. Given the high rate of comorbid depressive symptoms, antidepressant has been used. In an increasingly globalized world, clinicians must be able to properly diagnose and treat patients from other cultures, who may report symptoms that are influenced by their beliefs, culture, or place of origin. Dhat may be a common manifestation of a depressive or anxiety disorder in certain cultures. Further research is needed to improve our understanding of this condition, to clarify its nosologic status, and to offer appropriate treatment to affected individuals.

The quiet revolution: reporting of health outcomes in general medical journals.

PubMed

Seymour, J; Newell, D; Shiell, A

1997-01-01

This study reviews the extent of evaluation of health outcomes in three general medical journals over the past decade by examining papers published in the original research section of the New England Journal of Medicine (NEJM), The Lancet, and the Medical Journal of Australia (MJA) in 1982 and 1992. Evaluations were identified and classified according to the type of comparison group and the type of outcome measures employed. They were divided into three categories: those employing a comparison group; those employing a before-and-after study design (or own comparison group); and those with no comparison group. The categories of outcome measures were mortality, clinical or intermediate measures of health state, and final outcome measures (quality of life). Results show that the proportion of papers evaluating a health services intervention remained stable over the period. However, the MJA published considerably fewer evaluations than the other journals. In the NEJM and The Lancet, 75 per cent of evaluations incorporated comparison groups, in the MJA, less than 40 per cent. Overall, the proportion of papers reporting final outcome measures increased significantly between 1982 and 1992 (p = 0.04) but the change in each journal individually did not reach statistical significance. This study indicates that the reporting of health outcomes evaluations has remained constant but there has been some change in the use of comparison groups and final outcome measures over time.

With the tremendous advances in the field of brain-computer interfaces (BCI), the literature in this field has grown exponentially; examination of highly cited articles is a tool that can help identify outstanding scientific studies and landmark papers. This study examined the characteristics of 100 highly cited BCI papers over the past 10 years. The Web of Science was searched for highly cited papers related to BCI research published from 2006 to 2015. The top 100 highly cited articles were identified. The number of citations and countries, and the corresponding institutions, year of publication, study design, and research area were noted and analyzed. The 100 highly cited articles had a mean of 137.1(SE: 15.38) citations. These articles were published in 45 high-impact journals, and mostly in TRANSACTIONS ON BIOMEDICAL ENGINEERING (n=14). Of the 100 articles, 72 were original articles and the rest were review articles. These articles came from 15 countries, with the USA contributing most of the highly cited articles (n=52). Fifty-seven institutions produced these 100 highly cited articles, led by Duke University (n=7). This study provides a historical perspective on the progress in the field of BCI, allows recognition of the most influential reports, and provides useful information that can indicate areas requiring further investigation.

The Darwins and Wells: from revolution to evolution.

PubMed

Wade, Nicholas J

2010-04-08

In the biography of his grandfather (Erasmus Darwin), Charles Darwin hinted that his father (Robert Darwin) had received parental assistance in conducting and writing his medical thesis (which concerned afterimages). The experiments also involved visual vertigo, and they were elaborated by the senior Darwin in his Zoonomia, published in 1794. Erasmus Darwin's interpretation was in terms of trying to pursue peripheral afterimages formed during rotation; it was at variance with one published two years earlier by William Charles Wells, who had investigated the visual consequences of body rotation when the body is subsequently still. Wells penned two retorts to the Darwins' theory; although they were not accepted by Erasmus, he did devise a human centrifuge, models of which were employed in later studies of vertigo. Wells's ideas on evolution were expressed in a paper delivered to the Royal Society (in 1813) but not published in its Transactions. Commenting on the case of a white woman, part of whose skin was black, he proposed a process of change that was akin to natural selection. His ideas were acknowledged by Charles Darwin in the fourth edition of On the Origin of Species.

Profiling quinones in ambient air samples collected from the Athabasca region (Canada).

PubMed

Wnorowski, Andrzej; Charland, Jean-Pierre

2017-12-01

This paper presents new findings on polycyclic aromatic hydrocarbon oxidation products-quinones that were collected in ambient air samples in the proximity of oil sands exploration. Quinones were characterized for their diurnal concentration variability, phase partitioning, and molecular size distribution. Gas-phase (GP) and particle-phase (PM) ambient air samples were collected separately in the summer; a lower quinone content was observed in the PM samples from continuous 24-h sampling than from combined 12-h sampling (day and night). The daytime/nocturnal samples demonstrated that nighttime conditions led to lower concentrations and some quinones not being detected. The highest quinone levels were associated with wind directions originating from oil sands exploration sites. The statistical correlation with primary pollutants directly emitted from oil sands industrial activities indicated that the bulk of the detected quinones did not originate directly from primary emission sources and that quinone formation paralleled a reduction in primary source NO x levels. This suggests a secondary chemical transformation of primary pollutants as the origin of the determined quinones. Measurements of 19 quinones included five that have not previously been reported in ambient air or in Standard Reference Material 1649a/1649b and seven that have not been previously measured in ambient air in the underivatized form. This is the first paper to report on quinone characterization in secondary organic aerosols originating from oil sands activities, to distinguish chrysenequinone and anthraquinone positional isomers in ambient air, and to report the requirement of daylight conditions for benzo[a]pyrenequinone and naphthacenequinone to be present in ambient air.

Use of unsolicited first-person written illness narratives in research: systematic review.

PubMed

O'Brien, Mary R; Clark, David

2010-08-01

This paper is a report of a methodological systematic review conducted to critically analyze the use of unsolicited first-person written illness narratives for research purposes. Documenting illness experiences through written narratives enables individuals to record the impact of illness on themselves and those closest to them. In health research, unsolicited first-person written illness narratives are recognized increasingly as legitimate data sources. To date there has been no critical evaluation of the method. The ISI Web of Knowledge; CINAHL; PubMed; MEDLINE; PsycINFO; Science Direct; Cochrane Library databases and the internet metasearch engine 'Dogpile' were searched for the period up to 2009. The search terms were: 'patient experience', 'narratives', 'autobiography', 'pathography', 'written narratives', 'illness narratives', 'internet', 'published', 'unsolicited'. Recommendations within the Centre for Reviews and Dissemination guidance informed the review. Eligible studies were evaluated according to inclusion/exclusion criteria. The data were extracted by one reviewer and monitored by the second reviewer. Eighteen papers met the inclusion criteria, 12 from the original search in 2008 and six from the updated search in October 2009. Nine used unpublished (internet) narratives, eight used published (print) accounts and one drew on both genres. The method has been used to explore a wide range of illness experiences. There was lack of agreement on key terminology. Methodological issues were often poorly-described, and confused ethical stances were reported. The lack of methodological detail in published papers requires attention if this method is to be used effectively in healthcare research. The confused ethical stance adopted needs to be addressed and clarified. A theoretical conceptual framework to define and describe the method accurately is urgently required.

PHARMACEUTICAL PRICING IN EMERGING MARKETS: EFFECTS OF INCOME, COMPETITION, AND PROCUREMENT

This paper analyzes determinants of ex-manufacturer prices for originator and generic drugs across countries. We focus on drugs to treat HIV/AIDS, TB, and malaria in middle and low-income countries (MLICs), with robustness checks to other therapeutic categories and the full income range of countries. We examine the effects of per capita income, income dispersion, competition from originator and generic substitutes, and whether the drugs are sold to retail pharmacies versus tendered procurement by non-government organizations. The cross-national income elasticity of prices is 0.27 across the full income range of countries but is 0.0–0.10 between MLICs, implying that drugs are least affordable relative to income in the lowest income countries. Within-country income inequality contributes to relatively high prices in MLICs. Although generics are priced roughly 30% lower than originators on average, the variance is large. Additional generic competitors only weakly affect prices, plausibly because generic quality uncertainty leads to competition on brand rather than price. Tendered procurement that imposes quality standards attracts multinational generic suppliers and significantly reduces prices of originator and generic drugs, compared with their respective prices to retail pharmacies. ©2013 The Authors.

The ornithologist Alfred Russel Wallace and the controversy surrounding the dinosaurian origin of birds.

PubMed

Ibrahim, Nizar; Kutschera, Ulrich

2013-12-01

Over many years of his life, the British naturalist Alfred Russel Wallace (1823-1913) explored the tropical forests of Malaysia, collecting numerous specimens, including hundreds of birds, many of them new to science. Subsequently, Wallace published a series of papers on systematic ornithology, and discovered a new species on top of a volcano on Ternate, where he wrote, in 1858, his famous essay on natural selection. Based on this hands-on experience, and an analysis of an Archaeopteryx fossil, Wallace suggested that birds may have descended from dinosaurian ancestors. Here, we describe the "dinosaur-bird hypothesis" that originated with the work of Thomas H. Huxley (1825-1895). We present the strong evidence linking theropod dinosaurs to birds, and briefly outline the long and ongoing controversy around this concept. Dinosaurs preserving plumage, nesting sites and trace fossils provide overwhelming evidence for the dinosaurian origin of birds. Based on these recent findings of paleontological research, we conclude that extant birds indeed descended, with some modifications, from small, Mesozoic theropod dinosaurs. In the light of Wallace's view of bird origins, we critically evaluate recent opposing views to this idea, including Ernst Mayr's (1904-2005) arguments against the "dinosaur-bird hypothesis", and document that this famous ornithologist was not correct in his assessment of this important aspect of vertebrate evolution.

An explosive epidemic occurred in Madeira Island (Portugal) from October 2012 to February 2013. Published data showed that dengue virus type 1 introduced from South America was the incriminated virus. We aim to determine the origin of the strain introduced to Madeira by travellers returning to Europe. Using phylogeographic analysis and complete envelope sequences we have demonstrated that the most probable origin of the strain is Venezuela. Copyright © 2015 The Authors. Published by Elsevier Ltd..

Investigación Clínica has been published uninterruptedly for 55 years and for this reason, the University of Zulia has recognized the work of its editorial team with the imposition of the Order "Jesus Enrique Lossada". Despite some financial and structural problems we are optimistic because our journal has been included in new international indices and it is connected to the scientific world through the contributions from all continents; by the selfless collaboration of hundreds of domestic and foreign referees who respond with great professionalism; and through the visits to our website, from virtually around the world. Reviewing the SCImago statistical analysis, we found that among the Venezuelan medical journals, Investigación Clínica is first in cites per document (2 years) and second in the H index, and compares favorably with prestigious Latin-American journals. It is noteworthy that both in Venezuela and beyond our borders, the submission of topic reviews has increased in detriment of original papers or contributions. It seems that the lack of financial support to research institutes and universities, has led to a decline in experimental projects, at least in the medical field that occupies this journal, so researchers resort to reviews in their respective fields, as a compensation to maintain their productivity. This has caused that the Editorial Board has limited the reception of reviews to keep intact the percentage of published original contributions. Finally, we would like to think that there are no obstacles that can not be overcome to maintain our excellence in publishing Investigación Clínica.

Prior Publication and Redundancy in Contemporary Science: Are Authors and Editors at the Crossroads?

PubMed

de Vasconcelos, Sonia Maria Ramos; Roig, Miguel

2015-10-01

We discuss prior publication and redundancy in contemporary science in the context of changing perceptions of originality in the communication of research results. These perceptions have been changing in the publication realm, particularly in the last 15 years. Presenting a brief overview of the literature, we address some of the conflicts that are likely to arise between authors and editors. We illustrate our approach with conference presentations that are later published as journal articles and focus on a recent retraction of an article that had been previously published as a conference proceedings. Although we do not make definitive pronouncements on the matter-as many concepts are evolving-we do argue that conference papers that contain sufficient details for others to attempt a replication and are indexed in scientific databases such as PubMed, challenge some currently held assumptions of prior publication and originality in the sciences. Our view is that these important issues are in need of further clarification and harmonization within the science publishing community. This need is more evident when we consider current notions of research integrity when it comes to communication to peers. Revisiting long-standing views about what constitutes prior publication and developing a clearer set of guidelines for authors and editors to follow should reduce conflicts in the research environment, which already exerts considerable pressure, especially on newcomers in academia. However, while clearer guidelines are timely, developing them is only part of the challenge. The present times seem to call for deeper changes in the research and publication systems.

The G3 Experience with Electronic Publishing: An Editor's Perspective

NASA Astrophysics Data System (ADS)

White, W. M.

2003-12-01

G3 (Geochemistry, Geophysics, Geosystems) is an all-electronic journal published jointly by the AGU, the Geochemical Society, and the European Association of Geochemistry. G3 publishes original scientific contributions pertaining to understanding the Earth as a system, including relevant observational, experimental, and theoretical investigations of the solid Earth, hydrosphere, atmosphere, and biosphere. The journal was initiated as a result of a grass roots effort with the following goals in mind: a copyright policy designed to enhance, rather than inhibit, the dissemination of scientific information (for example, allowing authors to post electronic reprints on their web sites), provide a means of publishing, in immediately useable formats, large data sets, provide a means for ready dissemination of computer modeling and analysis tools, and provide a forum where authors could use novel ways of illustrating both data and models (e.g., formats such as movies, virtual reality images, sound, mathematical models, etc.), and finally to reduce costs and speed publication. In most respects, G3 has been enormously successful and has met most of its goals. G3 began publishing in December of 1999; in the subsequent 3 1/2 years 625 papers have been submitted to it and 325 have been published. It currently has over 600 institutional and personal subscribers. Papers are submitted through the web (a variety of formats are accepted, however, Microsoft Word is most common) and are converted to Adobe pdf format for peer review. Except that it is fully electronic using the web and e-mail, the peer review process is traditional, which insures the quality of the papers published. Accepted papers are copyedited and converted to SGML for archival purposes. HTML and Acrobat pdf versions are then generated from the SGML and published as they are ready on the G3 web site (www.g-cubed.org). Large data sets are routinely published in digital formats that can be readily downloaded by readers and immediately imported into programs such as Excel. Numerous animations and movies have been published in animated GIF, Apple Quicktime, Macromedia Flash, and Wolfram Research Mathreader formats. Computer models and tools have been published as Excel Macros and MATLAB Scripts. Full color, high resolution images allow superior publication of detailed maps and photographs. While G3 is a success by most measures, the process of pioneering electronic publication has at times been painful and frustrating. Early on, there were problems and delays in converting files, particularly graphics, to pdf format for both review and final publication. Costs have been higher than anticipated - primarily due to the cost of file conversion and formatting. The time from acceptance to publication (currently 10 weeks), although improving, it still longer than the goal, again because of the time required for copy-editing and formatting. Automation of this process in the future is the primary opportunity to both reduce cost and further speed publication. Authors have been slow to take advantage of the new illustration formats, with most relying on tradition figures instead. This will likely change slowly in the future, as these new formats, and the software tools to create them, become more familiar.

Enlarging the bounds of moral philosophy: Why did Isaac Newton conclude the Opticks the way he did?

PubMed Central

Henry, John

2017-01-01

This paper draws attention to the remarkable closing words of Isaac Newton's Optice (1706) and subsequent editions of the Opticks (1718, 1721), and tries to suggest why Newton chose to conclude his book with a puzzling allusion to his own unpublished conclusions about the history of religion. Newton suggests in this concluding passage that the bounds of moral philosophy will be enlarged as natural philosophy is ‘perfected’. Asking what Newton might have had in mind, the paper first considers the idea that he was foreshadowing the ‘moral Newtonianism’ developed later in the eighteenth century; then it considers the idea that he was perhaps pointing to developments in natural theology. Finally, the paper suggests that Newton wanted to at least signal the importance of attempting to recover the true original religion, and perhaps was hinting at his intention to publish his own extensive research on the history of the Church.

The US National Institutes of health, Fogarty International Center (NIH-FIC) has, for the past 13 years, been a leading funder of international research ethics education for resource-limited settings. Nearly half of the NIH-FIC funding in this area has gone to training programs that train individuals from sub-Saharan Africa. Identifying the impact of training investments, as well as the potential predictors of post-training success, can support curricular decision-making, help establish funding priorities, and recognize the ultimate outcomes of trainees and training programs. Comprehensive evaluation frameworks and targeted evaluation tools for bioethics training programs generally, and for international research ethics programs in particular, are largely absent from published literature. This paper shares an original conceptual framework, data collection tool, and detailed methods for evaluating the inputs, processes, outputs, and outcomes of research ethics training programs serving individuals in resource-limited settings. This paper is part of a collection of papers analyzing the Fogarty International Center’s International Research Ethics Education and Curriculum Development program. PMID:24782071

Republication of: Contributions to the theory of pure gravitational radiation. Exact solutions of the field equations of the general theory of relativity II

Jordan, Pascual; Ehlers, Jürgen; Sachs, Rainer K.

2013-12-01

This is an English translation of a paper by Pascual Jordan, Juergen Ehlers and Rainer Sachs, first published in 1961 in the proceedings of the Academy of Sciences and Literature in Mainz (Germany). The original paper was part 2 of a five-part series of articles containing the first summary of knowledge about exact solutions of Einstein's equations found until then. (Parts 1 and 4 of the series have already been reprinted, parts 3 and 5 will be printed as Golden Oldies in near future.) This second paper discusses the geometry of geodesic null congruences, the algebraic classification of the Weyl tensor by spinor methods, and applies these to a study of the propagation of gravitational and electromagnetic radiation. It has been selected by the Editors of General Relativity and Gravitation for republication in the Golden Oldies series of the journal. The republication is accompanied by an editorial note written by Malcolm A. H. MacCallum and Wolfgang Kundt.

Conservation of cultural heritage treasures is the most important issue for transferring knowledge to the public through the next generation of students, academics, and researchers. Although this century is authenticating e-books and information by means of electronic text, still historical manuscripts as content as well as objects are the main original recourses of keeping a record of this transformation. The current work focuses on cleaning paper samples by the application of pulsed light, which is interventional. Experiments carried out using paper samples that are artificially colonized with Ulocladium chartarum. Paper is treated by Nd:YAG laser light. The available wavelength is 1064 nm, at various fluences, repetition rates and number of pulses. Two types of paper are stained with fungi colonies, which grow on substrates of clean paper, as well as on paper with ink text. The first type of paper is Whatman No.1056, which is closer to pure cellulose. The second type of paper is a page of a cultural heritage book published in 1926. Cleaning is performed using laser irradiation, thus defining the damage threshold of each sample. The treatment on paper Watman showed a yellowing, especially on areas with high concentration of fungi. The second sample was more durable to the exposure, performing the best results at higher fluences. Eventually, the paper samples are characterized, with optical microscopy and SEM/EDX analyses, prior to and after cleaning.

Honoring the Past and Looking to the Future: Updates on Seminal Behavior Therapy Publications on Etiology and Mechanisms of Change.

PubMed

Newman, Michelle G

2016-09-01

This is the introduction to the first of two special issues in honor of the 50th anniversary of the Association for Behavioral and Cognitive Therapies. The goal of this issue is to pay tribute to prior seminal Behavior Therapy publications on etiology and mechanisms of change, to provide an updated review of important topics covered by these papers, and to make recommendations for the future. Each invited paper highlights a particular Behavior Therapy publication's contribution to our understanding and also provides an updated review or meta-analysis on the topic of the original paper. The topics covered here include mechanisms of etiology such as preparedness, reinforcement, and control. In terms of papers on mechanisms of change, we cover mechanisms related to extinction including fear activation, within- and between-session extinction, safety behaviors, and variables related to imagery. In addition, we examine principles related to generalization of learning and optimizing the impact of homework. With the two special issues of Behavior Therapy, we hope to inspire additional research and discussion. Copyright © 2016. Published by Elsevier Ltd.

DOORS to the semantic web and grid with a PORTAL for biomedical computing.

Taswell, Carl

2008-03-01

The semantic web remains in the early stages of development. It has not yet achieved the goals envisioned by its founders as a pervasive web of distributed knowledge and intelligence. Success will be attained when a dynamic synergism can be created between people and a sufficient number of infrastructure systems and tools for the semantic web in analogy with those for the original web. The domain name system (DNS), web browsers, and the benefits of publishing web pages motivated many people to register domain names and publish web sites on the original web. An analogous resource label system, semantic search applications, and the benefits of collaborative semantic networks will motivate people to register resource labels and publish resource descriptions on the semantic web. The Domain Ontology Oriented Resource System (DOORS) and Problem Oriented Registry of Tags and Labels (PORTAL) are proposed as infrastructure systems for resource metadata within a paradigm that can serve as a bridge between the original web and the semantic web. The Internet Registry Information Service (IRIS) registers [corrected] domain names while DNS publishes domain addresses with mapping of names to addresses for the original web. Analogously, PORTAL registers resource labels and tags while DOORS publishes resource locations and descriptions with mapping of labels to locations for the semantic web. BioPORT is proposed as a prototype PORTAL registry specific for the problem domain of biomedical computing.

PubMed Central

2017-01-01

Bibliometric indices are a widely used measure of research impact. The aim of the current study was to identify and characterise the top one hundred most-cited research articles in the topic of chronotype research. A search of the Thomson Reuters Web of Science database returned 974 eligible articles (published between 1990 and 2016). Citations for the 100 most-cited articles ranged between 438 and 29. The most represented journal was Chronobiology International (n = 30). Nearly 50% of articles originated in Germany and the U.S. The bibliometrics reported identify key publications and provide insight into trends within the topic of chronotype research.

The exact probability distribution of the rank product statistics for replicated experiments.

PubMed

Eisinga, Rob; Breitling, Rainer; Heskes, Tom

2013-03-18

The rank product method is a widely accepted technique for detecting differentially regulated genes in replicated microarray experiments. To approximate the sampling distribution of the rank product statistic, the original publication proposed a permutation approach, whereas recently an alternative approximation based on the continuous gamma distribution was suggested. However, both approximations are imperfect for estimating small tail probabilities. In this paper we relate the rank product statistic to number theory and provide a derivation of its exact probability distribution and the true tail probabilities.

The Origin of Gravitational Lensing: A Postscript to Einstein's 1936 Science Paper

PubMed

Renn; Sauer; Stachel

1997-01-10

Gravitational lensing, now taken as an important astrophysical consequence of the general theory of relativity, was found even before this theory was formulated but was discarded as a speculative idea without any chance of empirical confirmation. Reconstruction of some of Einstein's research notes dating back to 1912 reveals that he explored the possibility of gravitational lensing 3 years before completing his general theory of relativity. On the basis of preliminary insights into this theory, Einstein had already derived the basic features of the lensing effect. When he finally published the very same results 24 years later, it was only in response to prodding by an amateur scientist.

Between the years 1346 and 1353, a terrible epidemic swept over Western Asia, the Middle East, Africa, and Europe, causing catastrophic losses of population everywhere, both in the rural areas and in towns and cities. The Black Death was a disease of such magnitude that it not only shook the Old World to its economic and social foundations but changed the course of human history. The authors considered and analyzed many studies on the Black Death published in different languages. In the present paper they report medical and epidemiological specificities of the pandemic as well as its geographical origins and the routes of its spread.

Influence of Article Type on the Impact Factor of Dermatology Journals.

Rodríguez-Lago, L; Molina-Leyva, A; Pereiro-Ferreirós, M; García-Doval, I

2018-06-01

For scientific journals, achieving a high impact factor (IF) has become a goal in its own right. Our aim was to describe the influence of article type on the IF of dermatology journals. We used the Scopus database to calculate an IF for Actas Dermo-Sifiliográficas and the major dermatology journals, excluding articles without abstracts, letters to the editor, and conference proceedings. Included articles were classified into 4 categories: case reports, original articles, narrative reviews, and other. We also calculated the mean IF for each article type. We then compared our results with IFs published by the Institute for Scientific Information. The proportion of each type of article differed between journals. Original articles carried the greatest weight in the major journals (BJD, 76.8%; Contact, 81.1%; JAAD, 63.4%; JAMA Dermatol, 63.7%.) but not in Actas Dermo-Sifiliográficas, where only 31.7% were original research articles. A higher IF was associated with the publication of reviews and original articles; a lower IF was associated with the publication of case reports and other article types. Publishing case reports, which have lower citation rates, leads to a lower IF. Publishing reviews and original articles will lead to a higher IF. Journals that seek a higher IF should probably publish more reviews and original articles and fewer case reports. Editorial boards should seek a balance between the interests of their clinician readers and the journal's need for a higher IF.

The aims of this study were to evaluate the trends in funding, geographic origin, and study types of original articles in the dental implant literature and to investigate the relationships among these factors. Articles published in Clinical Oral Implants Research, The International Journal of Oral and Maxillofacial Implants, Clinical Implant Dentistry and Related Research, Implant Dentistry, and Journal of Oral Implantology from 2005 to 2009 were reviewed. Nonoriginal articles were excluded. For each article included, extramural funding source, geographic origin, and study type were recorded. Descriptive and analytic analyses (α = .05), including a logistic regression analysis, and chi-square test were used where appropriate. Of a total of 2,085 articles published, 1,503 met the inclusion criteria. The most common source of funding was from industry (32.4%). The proportion of studies that reported funding increased significantly over time. Europe represented the highest percentage (55.8%) of published articles. Most of the articles reported on clinical studies (49.9%), followed by animal studies (25.9%). Articles from Asia and South America and animal and in vitro studies were significantly more likely to be funded. Almost half of the original dental implant articles were funded. The trend toward internationalization of authorship was evident. A strong association was observed between funding and geographic origin and between funding and study type. Most studies in North America and Europe were clinical studies and supported by industry, whereas a greater proportion of studies in Asia and South America were in vitro or animal studies funded through government resources.
