    To evaluate control group selection in nonrandomized studies published in the Journal of Hand Surgery American (JHS). We reviewed all papers published in JHS in 2013 to identify studies that used nonrandomized control groups. Data collected included type of study design and control group characteristics. We then appraised studies to determine whether authors discussed confounding and selection bias and how they controlled for confounding. Thirty-seven nonrandomized studies were published in JHS in 2013. The source of control was either the same institution as the study group, a different institution, a database, or not provided in the manuscript. Twenty-nine (78%) studies statistically compared key characteristics between control and study group. Confounding was controlled with matching, exclusion criteria, or regression analysis. Twenty-two (59%) papers explicitly discussed the threat of confounding and 18 (49%) identified sources of selection bias. In our review of nonrandomized studies published in JHS, papers had well-defined controls that were similar to the study group, allowing for reasonable comparisons. However, we identified substantial confounding and bias that were not addressed as explicit limitations, which might lead the reader to overestimate the scientific validity of the data. Incorporating a brief discussion of control group selection in scientific manuscripts should help readers interpret the study more appropriately. Authors, reviewers, and editors should strive to address this component of clinical importance. Copyright © 2015 American Society for Surgery of the Hand. Published by Elsevier Inc.

    Empirical measurement of interventions to address significant global health and development problems is necessary to ensure that resources are applied appropriately. Such intervention programs are often deployed at the group or community level. The gold standard design to measure the effectiveness of community-level interventions is the community-randomized trial, but the conditions of these trials often make it difficult to assess their external validity and sustainability. The sheer number of community interventions, relative to randomized studies, speaks to a need for rigorous observational methods to measure their impact. In this article, we use the potential outcomes model for causal inference to motivate a matched cohort design to study the impact and sustainability of nonrandomized, preexisting interventions. We illustrate the method using a sanitation mobilization, water supply, and hygiene intervention in rural India. In a matched sample of 25 villages, we enrolled 1,284 children <5 y old and measured outcomes over 12 mo. Although we found a 33 percentage point difference in new toilet construction [95% confidence interval (CI) = 28%, 39%], we found no impacts on height-for-age Z scores (adjusted difference = 0.01, 95% CI = −0.15, 0.19) or diarrhea (adjusted longitudinal prevalence difference = 0.003, 95% CI = −0.001, 0.008) among children <5 y old. This study demonstrates that matched cohort designs can estimate impacts from nonrandomized, preexisting interventions that are used widely in development efforts. Interpreting the impacts as causal, however, requires stronger assumptions than prospective, randomized studies. PMID:21149699

    Systematic reviews within the Cochrane Effective Practice and Organisation of Care Group (EPOC) can include both randomized and nonrandomized study designs. We explored how many EPOC reviews consider and identify nonrandomized studies, and whether the proportion of nonrandomized studies identified is linked to the review topic. We recorded the study designs considered in 65 EPOC reviews. For reviews that considered nonrandomized studies, we calculated the proportion of identified studies that were nonrandomized and explored whether there were differences in the proportion of nonrandomized studies according to the review topic. Fifty-one (78.5%) reviews considered nonrandomized studies. Forty-six of these reviews found nonrandomized studies, but the proportion varied a great deal (median, 33%; interquartile range, 25--50%). Reviews of health care delivery interventions had lower proportions of nonrandomized studies than those of financial and governance interventions. Most EPOC reviews consider nonrandomized studies, but the degree to which they find them varies. As nonrandomized studies are believed to be at higher risk of bias and their inclusion entails a considerable effort, review authors should consider whether the benefits justify the inclusion of these designs. Research should explore whether it is more useful to consider nonrandomized studies in reviews of some intervention types than others. Copyright © 2013 Elsevier Inc. All rights reserved.

    Full Text Available Utilisation of meta-analysis is becoming more and more common in interventional cardiology. The aim of this statistical approach is to collect a large number of patients from randomized clinical studies and nonrandomized registries in order to obtain a pooled estimate of the results. Nevertheless, simply pooling these results without a correct methodological approach can easily lead to biased conclusions. In this report we analyse the possible methodological drawbacks of such an approach and we suggest a simplified check-list of items to be considered in the effort of building-up a meta-analysis from non-randomized studies.

    Systematic reviews that include nonrandomized studies (NRS) face a number of logistical challenges. However, the greatest threat to the validity of such reviews arises from the differing susceptibility of randomized controlled trials (RCTs) and NRS to selection bias. Groups compared in NRS are unlik

    Full Text Available Abstract Background There is an increasing number of meta-analyses including data from non-randomized studies for therapeutic evaluation. We aimed to systematically assess the methods used in meta-analyses including non-randomized studies evaluating therapeutic interventions. Methods For this methodological review, we searched MEDLINE via PubMed, from January 1, 2013 to December 31, 2013 for meta-analyses including at least one non-randomized study evaluating therapeutic interventions. Etiological assessments and meta-analyses with no comparison group were excluded. Two reviewers independently assessed the general characteristics and key methodological components of the systematic review process and meta-analysis methods. Results One hundred eighty eight meta-analyses were selected: 119 included both randomized controlled trials (RCTs and non-randomized studies of interventions (NRSI and 69 only NRSI. Half of the meta-analyses (n = 92, 49 % evaluated non-pharmacological interventions. “Grey literature” was searched for 72 meta-analyses (38 %. An assessment of methodological quality or risk of bias was reported in 135 meta-analyses (72 % but this assessment considered the risk of confounding bias in only 33 meta-analyses (18 %. In 130 meta-analyses (69 %, the design of each NRSI was not clearly specified. In 131 (70 %, whether crude or adjusted estimates of treatment effect for NRSI were combined was unclear or not reported. Heterogeneity across studies was assessed in 182 meta-analyses (97 % and further explored in 157 (84 %. Reporting bias was assessed in 127 (68 %. Conclusions Some key methodological components of the systematic review process—search for grey literature, description of the type of NRSI included, assessment of risk of confounding bias and reporting of whether crude or adjusted estimates were combined—are not adequately carried out or reported in meta-analyses including NRSI.

  10. A Study of Innovative Features in Scholarly Open Access Journals

    Science.gov (United States)

    2011-01-01

    Background The emergence of the Internet has triggered tremendous changes in the publication of scientific peer-reviewed journals. Today, journals are usually available in parallel electronic versions, but the way the peer-review process works, the look of articles and journals, and the rigid and slow publication schedules have remained largely unchanged, at least for the vast majority of subscription-based journals. Those publishing firms and scholarly publishers who have chosen the more radical option of open access (OA), in which the content of journals is freely accessible to anybody with Internet connectivity, have had a much bigger degree of freedom to experiment with innovations. Objective The objective was to study how open access journals have experimented with innovations concerning ways of organizing the peer review, the format of journals and articles, new interactive and media formats, and novel publishing revenue models. Methods The features of 24 open access journals were studied. The journals were chosen in a nonrandom manner from the approximately 7000 existing OA journals based on available information about interesting journals and include both representative cases and highly innovative outlier cases. Results Most early OA journals in the 1990s were founded by individual scholars and used a business model based on voluntary work close in spirit to open-source development of software. In the next wave, many long-established journals, in particular society journals and journals from regions such as Latin America, made their articles OA when they started publishing parallel electronic versions. From about 2002 on, newly founded professional OA publishing firms using article-processing charges to fund their operations have emerged. Over the years, there have been several experiments with new forms of peer review, media enhancements, and the inclusion of structured data sets with articles. In recent years, the growth of OA publishing has also been

    Black Studies scholars have shown interest in the core journal concept. Indeed, the idea of core journals for the study of the Black experience has changed several times since 1940. While Black Studies scholars are citing Black Studies journals with frequency, they also cite traditional disciplinary journals a great deal of the time. However,…

    The major component of a systematic review is assessment of the methodologic quality and bias of randomized and nonrandomized trials. While there are multiple instruments available to assess the methodologic quality and bias for randomized controlled trials (RCTs), there is a lack of extensively utilized instruments for observational studies, specifically for interventional pain management (IPM) techniques. Even Cochrane review criteria for randomized trials is considered not to be a "gold standard," but merely an indication of the current state of the art review methodology. Recently a specific instrument to assess the methodologic quality of randomized trials has been developed for interventional techniques. Our objective was to develop an IPM specific instrument to assess the methodological quality of nonrandomized trials or observational studies of interventional techniques. The item generation for the instrument was based on a definition of quality, to the extent to which the design and conduct of the trial were congruent with the objectives of the study. Applicability was defined as the extent to which procedures produced by the study could be applied using contemporary IPM techniques. Multiple items based on Cochrane review criteria and Interventional Pain Management Techniques - Quality Appraisal of Reliability and Risk of Bias Assessment for Nonrandomized Studies (IPM-QRBNR) were utilized. A total of 16 items were developed which formed the IPM-QRBNR tool. The assessment was performed in multiple stages. The final assessment was 4 nonrandomized studies. The inter-rater agreement was moderate to good for IPM-QRBNR criteria. Limited validity or accuracy assessment of the instrument and the large number of items to be scored were limitations. We have developed a new comprehensive instrument to assess the methodological quality of nonrandomized studies of interventional techniques. This instrument provides extensive information specific to interventional

    Study Objectives: Previous case reports of intravenous immunoglobulins (IVIg) in pediatric narcolepsy have shown contradictory results. Methods: This was a nonrandomized, open-label, controlled, longitudinal observational study of IVIg use in pediatric narcolepsy with retrospective data collection from medical files obtained from a single pediatric national reference center for the treatment of narcolepsy in France. Of 56 consecutively referred patients with narcolepsy, 24 received IVIg (3 infusions administered at 1-mo intervals) in addition to standard care (psychostimulants and/or anticataplectic agents), and 32 continued on standard care alone (controls). Results: For two patients in each group, medical files were unavailable. Of the 22 IVIg patients, all had cerebrospinal fluid (CSF) hypocretin ≤ 110 pg/mL and were HLA-DQB1*06:02 positive. Of the 30 control patients, 29 were HLA-DQB1*06:02 positive and of those with available CSF measurements, all 12 had hypocretin ≤ 110 pg/mL. Compared with control patients, IVIg patients had shorter disease duration, shorter latency to sleep onset, and more had received H1N1 vaccination. Mean (standard deviation) follow-up length was 2.4 (1.1) y in the IVIg group and 3.9 (1.7) y in controls. In multivariate-adjusted linear mixed-effects analyses of change from baseline in Ullanlinna Narcolepsy Scale (UNS) scores, high baseline UNS, but not IVIg treatment, was associated with a reduction in narcolepsy symptoms. On time-to-event analysis, among patients with high baseline UNS scores, control patients achieved a UNS score narcolepsy symptoms were not significantly reduced by IVIg. However, in patients with high baseline symptoms, a subset of IVIg-treated patients achieved remission more rapidly than control patients.

    Nearly two-thirds of women in their first postpartum year have an unmet need for family planning. Adolescents often have repeat pregnancies within a year of giving birth. Women may receive counseling on family planning both antepartum and postpartum. Decisions about contraceptive use made right after counseling may differ considerably from actual postpartum use. In earlier work, we found limited evidence of effectiveness from randomized trials on postpartum contraceptive counseling. For educational interventions, non-randomized studies may be conducted more often than randomized trials. We reviewed non-randomized studies of educational strategies to improve postpartum contraceptive use. Our intent was to examine associations between specific interventions and postpartum contraceptive use or subsequent pregnancy. We searched for eligible non-randomized studies until 3 November 2014. Sources included CENTRAL, PubMed, POPLINE, and Web of Science. We also sought current trials via ClinicalTrials.gov and ICTRP. For additional citations, we examined reference lists of relevant reports and reviews. The studies had to be comparative, i.e., have intervention and comparison groups. The educational component could be counseling or another behavioral strategy to improve contraceptive use among postpartum women. The intervention had to include contact within six weeks postpartum. The comparison condition could be another behavioral strategy to improve contraceptive use, usual care, other health education, or no intervention. Our primary outcomes were postpartum contraceptive use and subsequent pregnancy. Two authors evaluated abstracts for eligibility and extracted data from included studies. We computed the Mantel-Haenszel odds ratio (OR) for dichotomous outcomes and the mean difference (MD) for continuous measures, both with 95% Confidence Intervals (CI). Where studies used adjusted analyses for continuous outcomes, we presented the results as reported by the investigators

    Background Tennis elbow is a common disorder of the upper extremity. It can be treated conservatively in the majority of patients, but some resistant cases eventually can be treated by percutaneous release with good functional outcome. Materials and methods This non-randomized control trial was conducted at the Department of Orthopaedics Surgery in a tertiary care hospital from July 2015 to June 2016 on 50 patients who underwent percutaneous release of the common extensor origin using an 18 gauge hypodermic needle. These patients did not respond to conservative treatment including rest, nonsteroidal anti-inflammatory drugs (NSAIDS) and local steroid injections. The outcome was graded as Excellent, Good, Fair, and Poor. Results Fifty patients (50 elbows) were included in the study. Thirty-two patients were female (64%), and 18 were male (36%). The right side was affected in 37 patients (74%) and left side in 13 (26%). The time taken to achieve a completely pain-free elbow ranged from one day to two months (average of 26.2 days). Those who did not achieve a pain-free elbow had a residual pain of 1.5 to six on the visual analogue scale (VAS) (average 2.32). Excellent outcome was noticed in 24 patients (48%); Good result in eight patients (36% ); Fair in four patients (eight percent) and Poor in four patients (eight percent). Conclusion Tennis elbow probably results from the degenerative tear of the common extensor origin, and a percutaneous tenotomy using an 18 gauge hypodermic needle is a simple, safe, patient-friendly, efficient, and easily reproducible method of treating tennis elbow in those who are resistant to conservative treatment, and it can be done as an outpatient procedure.

    Full Text Available Gustav Torisson,1 Lennart Minthon,1 Lars Stavenow,2 Elisabet Londos1 1Clinical Memory Research Unit, Department of Clinical Sciences, Lund University, 2Department of Internal Medicine, Skåne University Hospital, Malmö, Sweden Background: The purpose of this study was to examine whether a multidisciplinary intervention targeting drug-related problems, cognitive impairment, and discharge miscommunication could reduce readmissions in a general hospital population. Methods: This prospective, non-randomized intervention study was carried out at the department of general internal medicine at a tertiary university hospital. Two hundred medical inpatients living in the community and aged over 60 years were included. Ninety-nine patients received interventions and 101 received standard care. Control/intervention allocation was determined by geographic selection. Interventions consisted of a comprehensive medication review, improved discharge planning, post-discharge telephone follow-up, and liaison with the patient's general practitioner. The main outcome measures recorded were readmissions and hospital nights 12 months after discharge. Separate analyses were made for 12-month survivors and from an intention-to-treat perspective. Comparative analyses were made between groups as well as within groups over time. Results: After 12 months, survivors in the control group had 125 readmissions in total, compared with 58 in the intervention group (Mann–Whitney U test, P = 0.02. For hospital nights, the numbers were 1,228 and 492, respectively (P = 0.009. Yearly admissions had increased from the previous year in the control group from 77 to 125 (Wilcoxon signed-rank test, P = 0.002 and decreased from 75 to 58 in the intervention group (P = 0.25. From the intention-to-treat perspective, the same general pattern was observed but was not significant (1,827 versus 1,008 hospital nights, Mann–Whitney test, P = 0.054.

    The purpose of this study was to identify predatory journals in nursing, describe their characteristics and editorial standards, and document experiences of authors, peer reviewers, and editors affiliated with these journals. Using two sources that list predatory journals, the research team created a list of nursing journals. In Phase One, the team collected data on characteristics of predatory nursing journals such as types of articles published, article processing charge, and peer review process. In Phase Two, the team surveyed a sample of authors, reviewers, and editors to learn more about their experiences with their affiliated journals. Data from the review of predatory nursing journals were analyzed using descriptive statistics. Written comments were summarized and categorized. There were 140 predatory nursing journals from 75 publishers. Most journals were new, having been inaugurated in the past 1 to 2 years. One important finding was that many journals only published one or two volumes and then either ceased publishing or published fewer issues and articles after the first volume. Journal content varied widely, and some journals published content from dentistry and medicine, as well as nursing. Qualitative findings from the surveys confirmed previously published anecdotal evidence, including authors selecting journals based on spam emails and inability to halt publication of a manuscript, despite authors' requests to do so. Predatory journals exist in nursing and bring with them many of the "red flags" that have been noted in the literature, including lack of transparency about editorial processes and misleading information promoted on websites. The number of journals is high enough to warrant concern in the discipline about erosion of our scholarly literature. Nurses rely on the published literature to provide evidence for high-quality, safe care that promotes optimal patient outcomes. Research published in journals that do not adhere to the highest

    In order to determine the effect of intracorneal rings (Intacs SK), when implanted in keratoconic patients, on corneal curvature, Uncorrected Visual Acuity (UCVA), Best Corrected Visual Acuity (BCVA) and on the progression of the cone through three years follow-up period. In this prospective nonrandomized study 114 eyes of 71 keratoconic patients (38 females and 33 males) were implanted with Intacs SK. Incisions were always made in the steep meridian. UCVA, BCVA, Corneal Topography (TMS) were measured pre and postoperatively and at intervals of 1, 3, 6 & 12 months then yearly for 3 consecutive years. Preoperative mean k-reading was 52.53 and 48.18, 49.56, 49.17, 48.51, 48.15 & 48.01 at 1, 3, 6, 12, 24 & 36 months postoperatively (P‹0.01). In terms of UCVA, 15.64% of patients gained more than 3 lines and 69.73% gained 1-3 lines with a total of 85.37% of patients gaining lines compared to their preoperative UCVA (P‹0.01) while 14.63% of cases did not gain any lines at 1 month postoperative. At three months postoperatively, 12.64% gained more than 3 lines, 71.15% gained 1-3 lines with a total of 83.79% while 16.21% did not gain any lines. Three years postoperative 11.82% of cases gained more than 3 lines, 73.23% gained 1-3 lines with a total of 85.05% while 14.95% did not gain any lines (P‹0.01). With regard to BCVA, 19.73% gained more than 3 lines, 68.26% gained 1-3 lines with a total of 87.99% of cases gaining lines compared to their preoperative BCVA (P‹0.01) while 12.01% did not gained any lines at 1 month postoperative. At three months postoperatively, 14.96% gained more than 3 lines, 70.19% gained 1-3 lines with a total of 85.15% while 14.85% did not gain any lines.

    Full Text Available Open Access of information has had great boom nowadays, meanwhile, some authors don’t want to disseminate their knowledge, making difficult the process mentioned before. Some Databases have being created to answer to this problem. Repositories and scientific magazines are other possibilities that the authors have to diffuse their knowledge. In this work it is made a bibliometric study of the electronic journal INFOCIENCIA during five years in which productivity of articles, the origin of bibliography, quantity of articles by themes and if the bibliography was update or not, were determined, for doing it an analysis of bibliometric character was made. It consisted on summarizing, reviewing, identifying and systematizing the obtained information by means of investigations. The obtained results were: The productivity of article has decreased during these five years, being 2008 the year of less production. The number of biographies varies in the evaluated period. The themes with more quantity of articles were: health, agriculture and education. It was proved that persons consulted more bibliography since 5 to 10 years, followed by the last 5 years.

  5. Data fabrication and other reasons for non-random sampling in 5087 randomised, controlled trials in anaesthetic and general medical journals.

    Randomised, controlled trials have been retracted after publication because of data fabrication and inadequate ethical approval. Fabricated data have included baseline variables, for instance, age, height or weight. Statistical tests can determine the probability of the distribution of means, given their standard deviation and the number of participants in each group. Randomised, controlled trials have been retracted after the data distributions have been calculated as improbable. Most retracted trials have been written by anaesthetists and published by specialist anaesthetic journals. I wanted to explore whether the distribution of baseline data in trials was consistent with the expected distribution. I wanted to determine whether trials retracted after publication had distributions different to trials that have not been retracted. I wanted to determine whether data distributions in trials published in specialist anaesthetic journals have been different to distributions in non-specialist medical journals. I analysed the distribution of 72,261 means of 29,789 variables in 5087 randomised, controlled trials published in eight journals between January 2000 and December 2015: Anaesthesia (399); Anesthesia and Analgesia (1288); Anesthesiology (541); British Journal of Anaesthesia (618); Canadian Journal of Anesthesia (384); European Journal of Anaesthesiology (404); Journal of the American Medical Association (518) and New England Journal of Medicine (935). I chose these journals as I had electronic access to the full text. Trial p values were distorted by an excess of baseline means that were similar and an excess that were dissimilar: 763/5015 (15.2%) trials that had not been retracted from publication had p values that were within 0.05 of 0 or 1 (expected 10%), that is, a 5.2% excess, p = 1.2 × 10(-7) . The p values of 31/72 (43%) trials that had been retracted after publication were within 0.05 of 0 or 1, a rate different to that for unretracted trials, p = 1.03

    The primary aim of this study was to assess the overall effectiveness of individual and group outpatient cognitive behavioral therapy (CBT) for adults with a primary anxiety disorder in routine clinical practice. We conducted a random effects meta-analysis of 71 nonrandomized effectiveness studies on outpatient individual and group CBT for adult anxiety disorders. Standardized mean gain effect sizes pre- to posttreatment, and posttreatment to follow-up are reported for disorder-specific symptoms, depression, and general anxiety. The mean dropout from CBT is reported. Outpatient CBT was effective in reducing disorder-specific symptoms in completer (d=0.90-1.91) and intention-to-treat samples (d=0.67-1.45). Moderate to large (d=0.54-1.09) and small to large effect sizes (d=0.42-0.97) were found for depressive and general anxiety symptoms posttreatment. Across all anxiety disorders, the weighted mean dropout rate was 15.06%. Posttreatment gains for disorder-specific anxiety were maintained 12months after completion of therapy. CBT for adult anxiety disorders is very effective and widely accepted in routine practice settings. However, the methodological and reporting quality of nonrandomized effectiveness studies must be improved. © 2013.

    We study the statistics of citations made to the indexed Science journals in the Journal Citation Reports during the period 2004-2013 using different measures. We consider different measures which quantify the impact of the journals. To our surprise, we find that the apparently uncorrelated measures, even when defined in an arbitrary manner, show strong correlations. This is checked over all the years considered. Impact factor being one of these measures, the present work raises the question whether it is actually a nearly perfect index as claimed often. In addition we study the distributions of the different indices which also behave similarly.

    Kidney and cardiovascular disease are widespread among populations with high prevalence of diabetes, such as American Indians participating in the Strong Heart Study (SHS). Studying these conditions simultaneously in longitudinal studies is challenging, because the morbidity and mortality associated with these diseases result in missing data, and these data are likely not missing at random. When such data are merely excluded, study findings may be compromised. In this article, a subset of 2264 participants with complete renal function data from Strong Heart Exams 1 (1989-1991), 2 (1993-1995), and 3 (1998-1999) was used to examine the performance of five methods used to impute missing data: listwise deletion, mean of serial measures, adjacent value, multiple imputation, and pattern-mixture. Three missing at random models and one non-missing at random model were used to compare the performance of the imputation techniques on randomly and non-randomly missing data. The pattern-mixture method was found to perform best for imputing renal function data that were not missing at random. Determining whether data are missing at random or not can help in choosing the imputation method that will provide the most accurate results.

    Radon bath is a well-established modality of balneotherapy for the management of degenerative musculoskeletal disorders. The present study was conducted to ascertain whether baths of relatively low (80 Bq/l) radon concentration have any influence on the functioning of the endocrine system. In the study, a non-randomized pilot study, 27 patients with degenerative musculoskeletal disorders received 30-min radon baths (of 31-32 degrees C temperature and 80 Bq/l average radon concentration) daily, for 15 days. Twenty-five patients with matching pathologies were subjected to balneotherapy according to the same protocol, using thermal water with negligible radon content (6 Bq/l). Serum thyroid stimulating hormone, prolactin, cortisol, adrenocorticotropic hormone, and dehydroepiandrosterone levels were measured before and after a balneotherapy course of 15 sessions. Comparison of the accumulated data using the Wilcoxon test did not reveal any significant difference between pre- and post-treatment values or between the two patient groups. It is noted that while the beneficial effects of balneotherapy with radon-containing water on degenerative disorders is widely known, only few data have been published in the literature on its effect on endocrine functions. The present study failed to demonstrate any substantial effect of thermal water with relatively low radon content on the functioning of the endocrine system.

    2015-01-01

    As per the present curriculum in India, pre- and paraclinical subjects are taught away from the clinical setting. Therefore, students fail to connect the subject taught through didactic lectures to the clinical setting. Team-based learning (TBL) can be used in conjunction with lectures to teach applied microbiology. This study aims to evaluate the effectiveness of TBL sessions in conjunction with lectures to enhance learning of applied microbiology, among Indian students. All students enrolled in the study were taught systemic bacteriology through lectures. Of the 88 students, 49 students (study group) attended TBL sessions on the topics of diarrhea, fever of unknown origin, urinary tract infection and 39 students (control group) preferred self-study on the topics without attending the TBL sessions. Students' feedback on their perception on TBL sessions was collected using a questionnaire of 10 items. The performance of both the groups on the pre- and post-test were analyzed using unpaired t-test and analysis of variance (ANOVA). Gender-wise performance within the teams was analyzed by paired t-test using SPSS version 12. The TBL group outperformed the self-study group on the post-test [F 1 = 5.521, P = 0.021]. Female students as a whole performed better than males on the pre-test, scoring higher within both the TBL and self-study groups. Male students in the TBL group performed significantly better on the post-test than female students who participated in TBL sessions (P = 0.013). Students generally enjoyed and appreciated the TBL sessions. TBL sessions can be used judiciously in combination with the lectures to enhance learning of applied microbiology in India. In this study, TBL improved the performance of male students over self-study, but performance for female students following TBL was no better than when they simply studied by themselves.

    Full Text Available Abstract Background The associations of pesticide exposure with disease outcomes are estimated without the benefit of a randomized design. For this reason and others, these studies are susceptible to systematic errors. I analyzed studies of the associations between alachlor and glyphosate exposure and cancer incidence, both derived from the Agricultural Health Study cohort, to quantify the bias and uncertainty potentially attributable to systematic error. Methods For each study, I identified the prominent result and important sources of systematic error that might affect it. I assigned probability distributions to the bias parameters that allow quantification of the bias, drew a value at random from each assigned distribution, and calculated the estimate of effect adjusted for the biases. By repeating the draw and adjustment process over multiple iterations, I generated a frequency distribution of adjusted results, from which I obtained a point estimate and simulation interval. These methods were applied without access to the primary record-level dataset. Results The conventional estimates of effect associating alachlor and glyphosate exposure with cancer incidence were likely biased away from the null and understated the uncertainty by quantifying only random error. For example, the conventional p-value for a test of trend in the alachlor study equaled 0.02, whereas fewer than 20% of the bias analysis iterations yielded a p-value of 0.02 or lower. Similarly, the conventional fully-adjusted result associating glyphosate exposure with multiple myleoma equaled 2.6 with 95% confidence interval of 0.7 to 9.4. The frequency distribution generated by the bias analysis yielded a median hazard ratio equal to 1.5 with 95% simulation interval of 0.4 to 8.9, which was 66% wider than the conventional interval. Conclusion Bias analysis provides a more complete picture of true uncertainty than conventional frequentist statistical analysis accompanied by a

    Job stress and burnout are highly frequent in healthcare professionals, and prevalence in nurses can be as high as 40%. Mindfulness-based interventions have been shown to be effective in reducing stress and increasing well-being in a wide range of populations and contexts. However, controlled studies with healthcare professionals, and especially nurses, are scarce. The aim of this study was to explore the effectiveness of an on-site, abbreviated mindfulness-based intervention for nurses, using a nonrandomized, wait-list comparison design. The effectiveness of the intervention was measured through several validated self-report measures that participants completed before and after the intervention, assessing burnout, compassion fatigue, psychological symptoms, mindfulness, self-compassion, experiential avoidances, rumination, and satisfaction with life. A sample of 94 oncology nurses agreed to participate in the study and self-selected into an experimental (n=45) and comparison condition (n=48). Complete data was obtained for 48 of the initial 94 participants, mainly due to poor follow-up data rather than high drop-out rate. Statistical analyses included a series of 2×2 ANOVAs and ANCOVAs. Results indicated that nurses in the intervention reported significant decreases in compassion fatigue, burnout, stress, experiential avoidance, and increases in satisfaction with life, mindfulness and self-compassion, with medium to large effect sizes. Nurses in the comparison group didn't present significant changes in these variables. Results also pointed to a high degree of acceptability of the intervention. This study provides preliminary evidence that mindfulness-based interventions may be efficacious in reducing oncology nurses' psychological symptoms and improving their overall well-being, and thus may be worthy of further study in this population.

    Background. Dysphagia is one of the most common complications of stroke. Acupuncture is widely employed to treat poststroke dysphagia in East Asia. No evidence is established to support such treatment approach. This proposed study aims to evaluate the effectiveness and safety of acupuncture for the treatment of poststroke dysphagia. Methods and Design. This is a multicenter, pragmatic, single-blinded, nonrandomized controlled clinical trial. A total of 140 eligible patients will be enrolled in the study. Subjects who are eligible in study but refuse to have acupuncture treatment will be put on the no-acupuncture control arm. Both groups of patients will receive standard routine care, while the patients of intervention group will receive add-on standardized acupuncture treatment. Each participant in intervention group will receive a total of 24 sessions of acupuncture treatment (three times per week). The primary outcome measure is the Royal Brisbane Hospital Outcome Measure for Swallowing (RBHOMS). Secondary outcome measures include functional oral intake scale, swallow quality-of-life questionnaire in Chinese version, BMI of the participant, and adverse events. All outcome measures will be assessed at baseline, at the end of acupuncture treatment (month 2), and at two months after treatment (month 4). Ethics and Dissemination. The ethics approval of clinical research study was granted by the Research Ethics Committee of both New Territories East and West Cluster of Hong Kong. Written informed consent will be obtained from all participants and the study will be undertaken according to the ICH-GCP Guidelines. Trial Registration. This trial is registered with chictr.org (registration number: ChiCTR-TRC-12002621 and registration date: 2012-10-26). PMID:28246537

    To determine the acceptability of taking mifepristone at home for early medical abortion in the United States. This prospective, non-randomized, open-label study at six Planned Parenthood centers gave women with pregnancies up to 63 days' gestation seeking medical abortion the choice of taking mifepristone in the center or at home. Participants were interviewed at a follow-up visit 1-2 weeks after mifepristone administration to assess their experience with the option they selected. Four-hundred women were enrolled between April 2013 and June 2014 of which 32% (n=128) chose to take mifepristone at home. Abortion success rates did not differ between home and center users (96% and 97%). Among home users, 82% reported taking the mifepristone at the time they planned with their provider and no participant took it after 63 days' gestation. The most common reason cited for selecting home use was scheduling flexibility and significantly more home users took misoprostol on the weekend (50% vs. 36%, p=.02). Home users were more likely than center users to report missing no days of work due to the abortion (47% vs. 28%, p=.08). Ninety-nine percent of home users reported that they would take mifepristone at home again and 96% would recommend home use to a friend. Offering this option did not increase the service delivery burden on study providers, who would recommend home use in the future for most participants. Home use of mifepristone is a highly acceptable practice for which there is current demand, and it should be offered as part of routine medical abortion services. Offering the option of home use of mifepristone to medical abortion patients can provide women and clinics with more flexibility while maintaining a safe, effective and acceptable service. These results provide support for telemedicine or pharmacy distribution. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Introduction: Kiwifruit consumption has shown to improve functional constipation in healthy elderly population, according to studies in New Zealand and China. The aim of this study was to evaluate the effect of kiwifruit intake on functional constipation in a Mediterranean patient population characterized by its distinctive nutritional habits.Material and Methods: An open, non-controlled and non-randomized longitudinal study was conducted in 46 patients with constipation (Rome III criteria. Patients monitored for five weeks: weeks 1 and 2 no kiwifruit and weeks 3-5 three kiwifruit per day (Green kiwifruit, Actinidia deliciosa var Hayward. Bristol Scale, volume of stools, and ease of defecation was self- reported daily. The evolution of the categorical variables was tested using the Bhapkar test; functional data methodology was used for continuous variables, and Generalized Estimating Equation (GEE models were adjusted.Results: The percentage of patients with ≥3 stools per week increased from 82.61% (95% CI: 69–91.2 at week 1 to 97.78% (95% CI: 87.4–99.9 at week 2 of kiwifruit intake, with 76.09% (95% CI: 61.9–86.2 responding during the first week. The reporting of stable ideal stools increased from 17.39% (95% CI: 8.8–31 at week 2 to 33.33% (95% CI: 21.3–48 at week 5. According to GEE models, the number of depositions increased significantly (p-values<0.001 in 0.398 daily units at week 1 the first week of intake, up to 0.593 daily units at week 5; significant improvements on facility in evacuation and volume of evacuation were found from the firstweek of intake (all p-values<0.001.Conclusions: The intake of three kiwifruits per day significantly improves the quality of evacuation (number of depositions, volume, consistency and ease in a Mediterranean patient population suffering from functional constipation.

    BACKGROUND: Encephalofluctuograph Technology (ET) is an advanced and non-traumatic analytical method of brain function. ET can acquire super-slow waves from electroencephalic signals. Studies have shown that these particular spectra can reflect neurochemical processes in the brain. OBJECTIVE: To verify neurotransmitter changes in the brains Parkinson's disease (PD) patients through the use of ET. DESIGN, TIME AND SETTING: A non-randomized concurrent control experiment was performed at the Department of Neurology in Southern Building, General Hospital of Chinese PLA from August to December 2007. PARTICIPANTS: Sixty-one outpatients with PD were selected from the General Hospital of Chinese PLA from August 2007 to December 2007. In addition, 48 healthy subjects were selected as normal controls. METHODS: All patients underwent assessment of the sub scale Ⅱ,Ⅲ, and V of the Unified Parkinson's Disease Rating Scale (UPDRS), in which part Ⅱ was used to inform activity of daily living, part Ⅲ reflected athletic ability, and part Ⅴ was the Hoehn & Yahr grade for symptoms evaluation. Correlation analysis was performed between dopamine levels and UPDRS assessment. Neurotransmitter changes were observed forty-eight prior to and 1.5 hours after medicating with Benserazide. The S1, S2, S4, S5,S7, and S11 spectras respectively reflect gamma-aminobutyric acid (GABA), glutamic acid (Glu), 5-hydroxytryptamine (5-HT), acetylcholine (ACh), norepinephrine, and dopamine. MAIN OUTCOME MEASURES: Neurotransmitter changes in the brains of all subjects, and correlations between dopamine concentrations and UPDRS assessment. Neurotransmitter changes in a subgroup of patients prior to and 1.5 hours after medicating with Benserazide. RESULTS: Concentrations of 5-HT, ACh, and norepinephrine were decreased in the PD group, and GABA was increased. However, there was no significant difference compared with the normal control group (P > 0.05). The level of dopamine in PD group was

    Full Text Available The journal is fundamental to formal scholarly communication. This research reports highlights and preliminary findings from an empirical study of scholarly electronic journals. The purpose of the research is to assess the impact of electronic journals (e-journals on scholarly communication, by measuring the extent to which they are being cited in the literature, both print and electronic. The intent is to provide a snapshot of the impact e-journals were having on scholarly communication at a given point in time, roughly the end of 1995. This study provides one measure of that impact, specifically on the formal, as opposed to informal, communication process. The study also examines the forms in which scholars cite e-journals, the accuracy and completeness of citations to e-journals, and practical difficulties faced by scholars and researchers who wish to retrieve e-journals through the networks.

    Yamazaki, Shigeaki

    There have been hot discussions about the number and the rate of growth of scientific journals. The purpose of this review is intended to provide a critical assessment of those ecological studies on scientific journals. In 1961, Price presented his famous graph curve, and noted that rate of growth of journals had been fairly consisted at 5 per cent annum for nearly 300 years. But Price's graph curve has some primary error, and the author suggest to examine carefully his study. There is another problem that the loose definition of scientific journals is used. The author try to give a clear definition on the term ‘scientific journals’, and try to reestimate historically the growth rate in numbers of current scientific journals, referring several reliable studies previously conducted. The Author's estimation is about 1.85 per cent a year from the last of 18 century.

  14. Feminist Approaches to Journalism Studies: Canadian Perspectives

    Directory of Open Access Journals (Sweden)

    Gertrude J. Robinson

    2008-01-01

    Full Text Available One of the orthodoxies of communication scholarship is that much of the gender-based differences between males and females with regard to experiences in newsrooms can be attributed to demographics. The discussion presented in this paper challenges this claim by comparing the findings of two national surveys that measured the professional progress of Canadian press and television journalists. The first survey was undertaken in 1975, and the second in 1995. While the historical evidence points to reductions in gender-based structural inequalities over time, it also identifies the continued presence of gender-based assumptions about how work and family obligations should be combined. Such assumptions, it is argued, help to foster and reproduce systemic biases in the newsroom culture that still resonate today in the journalism profession and which can be best understood as a manifestation of the meaning of gender at three levels: as a classifying system, as a structuring structure, and as an ideology.

In this study, we first introduced top journals of obstetrics and gynecology field based on their Impact Factor (IF), Eigenfactor Score (ES) and SCImago Journal Rank (SJR) indicator indexed in Scopus databases and then the scientometric features of longitudinal changes of SJR in this field were presented. In our analytical and bibiliometric study, we included all the journals of obstetrics and gynecology field which were indexed by Scopus from 1999 to 2013. The scientometric features in Scopus were derived from SCImago Institute and IF and ES were obtained from Journal Citation Report through the Institute for Scientific Information. Generalized Estimating Equation was used to assess the scientometric features affecting SJR. From 256 journals reviewed, 54.2% and 41.8% were indexed in the Pubmed and the Web of Sciences, respectively. Human Reproduction Update based on the IF (5.924±2.542) and SJR (2.682±1.185), and American Journal of obstetrics and gynecology based on the ES (0.05685±0.00633) obtained the first rank among the other journals. Time, Index in Pubmed, H_index, Citable per Document, Cites per Document, and IF affected changes of SJR in the period of study. Our study showed a significant association between SJR and scientometric features in obstetrics and gynecology journals. According to this relationship, SJR may be an appropriate index for assessing journal quality.

    Chun, Y. C.; Yoo, J. B. [Korea Atomic Energy Research Institute, Taejon (Korea, Republic of)

    2006-07-01

    This paper is intended to provide some thoughts for a listing of the Korean nuclear journals in the Science Citation Index(SCI), by an analysis of indicators based on the data gathered from relevant literature : Journal of Korean Nuclear Society(JKNS) and Nuclear Engineering and Technology (NET) as cited in the SCI source journal. The study examines as an indicator the number of papers in the JKNS and NET that have been cited by KAERI researchers in the SCI Source Journal (to the end of August 2006). This paper also gives a review of the statistics provided by the Institute for Scientific Information (ISI), as an authoritative source for an evaluation of a global cataloguing of scientific and technical journals, and suggests a view for a listing of the Korean nuclear journals in the SCI by a review of associated selection criteria and methods. It concludes there is a need to increase the number of citations in the SCI source journals of the NET papers to be published from the most recent previous two years.

    Full Text Available Objective: To assess incidence, causality, severity, predictability and preventability of adverse drug reactions (ADRs in hospitalised oncology patients.Materials and Methods: A prospective observational, non-randomized, parallel sequence study was conducted at Dr B. Borooah Cancer Institute (BBCI after getting an approval from human ethical committee. Patients hospitalised at BBCI from Aug 2010 to June 2011 were interviewed about symptoms related to their drug therapy. Patient medical records were also reviewed for data collection.Results: Total 663 patients associated with hospitalizations were interviewed. 899 ADRs were identified in total 410 (61.84% patients detected with ADRs. Most of all ADRs were moderate, predictable and not preventable. The most common ADRs were leucopenia, weakness, anorexia, alopecia, vomiting, diarrhoea, nausea, abdominal pain, fatigue, and anaemia in this study.Conclusions: For definite conclusion study should be repeated. Strict drug analyzing and in vivo study is also required if feasible.Key message: The process of defining and concluding about ADRs should be continuous and ongoing to keep a record of newly marketed drugs and medicinal products.

    Full Text Available Abstract Background In some clinical situations, for which RCT are rare or impossible, the majority of the evidence comes from observational studies, but standard estimations could be biased because they ignore covariates that confound treatment decisions and outcomes. Methods Three observational studies were conducted to assess the benefit of Allo-SCT in hematological malignancies of multiple myeloma, follicular lymphoma and Hodgkin’s disease. Two statistical analyses were performed: the propensity score (PS matching approach and the inverse probability weighting (IPW approach. Results Based on PS-matched samples, a survival benefit in MM patients treated by Allo-SCT, as compared to similar non-allo treated patients, was observed with an HR of death at 0.35 (95%CI: 0.14-0.88. Similar results were observed in HD, 0.23 (0.07-0.80 but not in FL, 1.28 (0.43-3.77. Estimated benefits of Allo-SCT for the original population using IPW were erased in HR for death at 0.72 (0.37-1.39 for MM patients, 0.60 (0.19-1.89 for HD patients, and 2.02 (0.88-4.66 for FL patients. Conclusion Differences in estimated benefits rely on whether the underlying population to which they apply is an ideal randomized experimental population (PS or the original population (IPW. These useful methods should be employed when assessing the effects of innovative treatment in non-randomized experiments.

    Full Text Available Background. Fibromyalgia (FMS is a challenging condition for health care systems worldwide. Only limited trial data is available for FMS for outcomes of complex treatment interventions of complementary and integrative (CIM approaches. Methods. We conducted a controlled, nonrandomized feasibility study that compared outcomes in 21 patients treated with Ayurveda with those of 11 patients treated with a conventional approach at the end of a two-week inpatient hospital stay. Primary outcome was the impact of fibromyalgia on patients as assessed by the FIQ. Secondary outcomes included scores of pain intensity, pain perception, depression, anxiety, and quality of sleep. Follow-up assessments were done after 6 months. Results. At 2 weeks, there were comparable and significant improvements in the FIQ and for most of secondary outcomes in both groups with no significant in-between-group differences. The beneficial effects for both treatment groups were partly maintained for the main outcome and a number of secondary outcomes at the 6-month followup, again with no significant in-between-group differences. Discussion. The findings of this feasibility study suggest that Ayurvedic therapy is noninferior to conventional treatment in patients with severe FMS. Since Ayurveda was only used as add-on treatment, RCTs on Ayurveda alone are warranted to increase model validity. This trial is registered with NCT01389336.

    Hepatic cirrhosis is one of the leading causes of death worldwide, especially if complicated by ascites. This chronic condition can be related to the classical disease entity jalodara in Traditional Indian Medicine (Ayurveda). The present paper aims to evaluate the general potential of Ayurvedic therapy for overall clinical outcomes in hepatic cirrhosis complicated by ascites (HCcA). In form of a nonrandomized, uncontrolled, single group, open-label observational clinical study, 56 patients fulfilling standardized diagnostic criteria for HCcA were observed during their treatment at the P. D. Patel Ayurveda Hospital, Nadiad, India. Based on Ayurvedic tradition, a standardized treatment protocol was developed and implemented, consisting of oral administration of single and compound herbal preparations combined with purificatory measures as well as dietary and lifestyle regimens. The outcomes were assessed by measuring liver functions through specific clinical features and laboratory parameters and by evaluating the Child-Pugh prognostic grade score. After 6 weeks of treatment and a follow-up period of 18 weeks, the outcomes showed statistically significant and clinically relevant improvements. Further larger and randomized trials on effectiveness, safety, and quality of the Ayurvedic approach in the treatment of HCcA are warranted to support these preliminary findings.

    Probiotic supplementation has been part of the discussion on methods to enhance humoral immunity. Administration of Bifidobacterium bifidum OLB6378 (OLB6378) reduced the incidence of late-onset sepsis in infants. In this non-randomized study, we aimed to determine the effect of administration of live OLB6378 on infants’ humoral immunity. Secondly, we tried to elucidate whether similar effects would be observed with administration of non-live OLB6378. Low birth weight (LBW) infants weighing 1500–2500 g were divided into three groups: Group N (no intervention), Group L (administered live OLB6378 concentrate), and Group H (administered non-live OLB6378 concentrate). The interventions were started within 48 h after birth and continued until six months of age. Serum immunoglobulin G (IgG) levels (IgG at one month/IgG at birth) were significantly higher in Group L than in Group N (p food ingredient, showed a more marked effect than the viable bacteria.

    Spiritual care is still in infancy stage all over the globe including India. The present study was an original study evaluating the role of spiritual care in cancer patients and their primary caregivers regarding their spiritual and general well-being. The study was a prospective, non-randomized single-group study involving cancer patients undergoing surgery and their primary caregivers. Functional assessment of cancer therapy-general and functional assessment of chronic illness therapy-spiritual care was evaluated during the admission and at the time of discharge, two, four  and 6 months following discharge from the hospital. Descriptive statistics was used for demographic details and repeated measure ANOVA with Dunn's test was used for analysis of changes in the scores. A total of 107 (63 males and 44 females) patients with a mean (SD) of age 51 (13) years were recruited in the study. Similarly, for each patient one of their primary caregivers was recruited with their mean (SD) age of 39.4 (12.7) years. A total of 11/107 (10.3%) patients died and nine out of 107 (8.4%) were lost to follow-up eventually during the study period. There was a statistically significant (P spiritual care on the basis of MATCH guideline improved the level of not only spiritual well-being but general well-being also in both the patients and their primary caregivers. Control group could have improved scientific validity of study in accessing effect of spiritual care. Authors believe that more robust comparative study on each principle against all five MATCH principles in future will add scientific validity and clear the various ambiguities in spiritual care.

Recombinant human soluble thrombomodulin (rhTM is a new drug for the treatment of disseminated intravascular coagulation in Japan. The objective of this study was to evaluate the efficacy of rhTM for AE of IPF/NSIP.Methods: Twenty-two patients with AE-idiopathic interstitial pneumonia (16 patients with IPF and six patients with NSIP were enrolled in our study. Among them, eleven patients were treated with rhTM (rhTM group, and eleven patients were treated without rhTM (non-rhTM group. Patients admitted to our hospital prior to December 2013 were treated with rhTM, while those admitted after January 2014 were treated without rhTM. The primary endpoint was mortality at 90 days after AE treatment. The secondary endpoint was the safety of rhTM for AE-IPF/AE-NSIP. In addition, we examined prognostic factors of AE-IPF/AE-NSIP.Results: The mortality rate was significantly lower in the rhTM group than in the non-rhTM group (mortality rate at 90 days: 36% vs 90%, P=0.023; median survival time: not reached vs 15.0 days, P=0.019. A univariate analysis revealed the respiratory rate (hazard ratio [HR] 1.09, 95% confidence interval [CI] 1.00–1.18, P=0.039 and rhTM administration (HR 0.21, 95% CI 0.06–0.77, P=0.013 as predictors of mortality at 90 days, and a multivariate analysis identified rhTM administration (HR 0.025, 95% CI 0.0006–0.94, P=0.046 as an independent predictor of mortality at 90 days.

Transcatheter arterial chemoembolization (TACE) is the standardized therapy for the intermediate stage of HCC. However, the 3-year overall survival remains low (<30 %) in these patients. Thus, there is a critical need for the development of treatment modalities to improve the survival rate. This study aimed to evaluate whether the combination of {sup 131}I-metuximab with chemoembolization could improve treatment efficiency. Between January 2009 and January 2010, a prospective two-arm nonrandomized study was performed in patients with intermediate HCC. Of 138 patients, 68 (combination therapy group) received 132 courses of intraarterial {sup 131}I-metuximab injections combined with chemoembolization (mean 1.94 per patient, median 2, range 1-2), followed by 152 sessions of TACE (mean 2.24 per patient, median 2, range 0-4). The remaining 70 patients (monotherapy group) received 296 sessions of TACE (mean 4.23 per patient, median 4, range 1-7). The overall median survival times for the combination therapy group and the group treated only with TACE were 26.7 months (95 % CI 20.7-31.3 months) and 20.6 months (95 % CI 15.3-24.7 months), respectively. The combination therapy group had a significantly higher survival rate than the TACE-only group (P = 0.038). Age {>=}65 years, serum albumin {<=}35 g/l, and treatment category (combination therapy or TACE only) were independent prognostic factors for survival according to multivariate analysis. The combination of {sup 131}I-metuximab and chemoembolization extended survival in patients with intermediate HCC compared with TACE only, and was well tolerated by patients with Child-Pugh class A or B disease. This combination seems to be a promising treatment modality for patients with intermediate HCC. (orig.)

    Full Text Available Abstract Background Outcome data on two-stage revision surgery for deep infection after septic hip arthritis are limited and inconsistent. This study presents the medium-term results of a new, standardized two-stage arthroplasty with preformed hip spacers and cementless implants in a consecutive series of adult patients with septic arthritis of the hip treated according to a same protocol. Methods Nineteen patients (20 hips were enrolled in this prospective, non-randomized cohort study between 2000 and 2008. The first stage comprised femoral head resection, debridement, and insertion of a preformed, commercially available, antibiotic-loaded cement hip spacer. After eradication of infection, a cementless total hip arthroplasty was implanted in the second stage. Patients were assessed for infection recurrence, pain (visual analog scale [VAS] and hip joint function (Harris Hip score. Results The mean time between first diagnosis of infection and revision surgery was 5.8 ± 9.0 months; the average duration of follow up was 56.6 (range, 24 - 104 months; all 20 hips were successfully converted to prosthesis an average 22 ± 5.1 weeks after spacer implantation. Reinfection after total hip joint replacement occurred in 1 patient. The mean VAS pain score improved from 48 (range, 35 - 84 pre-operatively to 18 (range, 0 - 38 prior to spacer removal and to 8 (range, 0 - 15 at the last follow-up assessment after prosthesis implantation. The average Harris Hip score improved from 27.5 before surgery to 61.8 between the two stages to 92.3 at the final follow-up assessment. Conclusions Satisfactory outcomes can be obtained with two-stage revision hip arthroplasty using preformed spacers and cementless implants for prosthetic hip joint infections of various etiologies.

    Citation rates and impact factors are often used in an attempt to evaluate the apparent prestige of scholarly journals and the quality of research published by individual scholars. However, the apparent prestige of "top tier" journals may reflect aggressive marketing and advertising efforts as much as scholarship. Some journals have retained their independence from professional organizations and the funding, marketing, and advocacy policies that may be associated with such organizations. While lacking as much visibility as organizational journals and sometimes considered "lower tier," independent journals may be able to provide comparable scientific quality as measured by citation rates. To test this, the citation rates of 169 articles published by a frequently cited scholar were compared across first- and second-tier journals, including many sponsored and marketed by large professional organizations, and to rates for two independent journals combined, Psychological Reports and Perceptual and Motor Skills. Citation rates were higher for first-tier journals but for most comparisons, especially those that controlled for heterogeneity of variance, results did not differ in statistically significant ways among the three tiers of journals, though some nonsignificant trends (p journals appear to be a relatively weak indicator of scientific merit; journals at any tier contain articles that are useful and of good quality.

    This research analyzes a "who cites whom" matrix in terms of aggregated, journal-journal citations to determine the location of communication studies on the academic spectrum. Using the Journal of Communication as the seed journal, the 2006 data in the Journal Citation Reports are used to map communication studies. The results show that social and experimental psychology journals are the most frequently used sources of information in this field. In addition, several journals devoted to the use and effects of media and advertising are weakly integrated into the larger communication research community, whereas communication studies are dominated by American journals.

    Full Text Available BACKGROUND: Little evidence exists regarding efficacious HIV and sexually transmitted infections (STI prevention interventions with internally displaced populations. Internally displaced women are at elevated risk for HIV/STI due to limited access to health services, heightened poverty and social network breakdown. The FASY (Famn an Aksyon Pou Sante' Yo (Women Taking Action For Their Health study examined the effectiveness of a peer health worker (PHW delivered psycho-educational HIV/STI pilot study with internally displaced women in Leogane, Haiti. METHOD: This was a non-randomized cohort pilot study. Participants completed a computer-assisted pre-test programmed on Android tablet PCs followed by an HIV/STI educational video-based session and a 6-week psycho-educational group program of weekly meetings. Participants completed a post-test upon completion of group sessions. The primary outcome was HIV knowledge; our pre-specified index of clinically significant change was an effect size of 0.30. Secondary outcomes included: STI knowledge, condom use, social support, resilient coping, depression and relationship control. We used mixed-effects regression to calculate mean outcome pre-post score change. This study was registered (clinicaltrials.gov, NCT01492829.

    Full Text Available Abstract Background Taxane-platinum therapy (TP has replaced platinum-based therapy (PC or PAC, DNA damaging chemotherapy in the postoperative treatment of ovarian cancer patients; however, it is not always effective. TP53 protein plays a differential role in response to DNA-damaging agents and taxanes. We sought to define profiles of patients who benefit the most from TP and also of those who can be treated with PC. Methods We compared the effectiveness of PC/PAC (n = 253 and TP (n = 199 with respect to tumor TP53 accumulation in ovarian cancer patients with FIGO stage IIB-IV disease; this was a non-randomized retrospective study. Immunohistochemical analysis was performed on 452 archival tumors; univariate and multivariate analysis by the Cox's and logistic regression models was performed in all patients and in subgroups with [TP53(+] and without TP53 accumulation [TP53(-]. Results The advantage of taxane-platinum therapy over platinum-based therapy was seen in the TP53(+, and not in the TP53(- group. In the TP53(+ group taxane-platinum therapy enhanced the probability of complete remission (p = .018, platinum sensitivity (p = .014, platinum highly sensitive response (p = .038 and longer survival (OS, p = .008. Poor tumor differentiation diminished the advantage from taxane-platinum therapy in the TP53(+ group. In the TP53(- group PC/PAC was at least equally efficient as taxane-platinum therapy and it enhanced the chance of platinum highly sensitive response (p = .010. However, in the TP53(- group taxane-platinum therapy possibly diminished the risk of death in patients over 53 yrs (p = .077. Among factors that positively interacted with taxane-platinum therapy in some analyses were endometrioid and clear cell type, FIGO III stage, bulky residual tumor, more advanced age of patient and moderate tumor differentiation. Conclusion Our results suggest that taxane-platinum therapy is particularly justified in patients with TP53(+ tumors or older

    Laparoscopic left pancreatic resections are being increasingly performed. In this study, we provide a nonrandomized comparison between laparoscopic and open left pancreatectomy (OLP) for benign and borderline tumors, focusing on both perioperative and long-term results. Demographic, pathologic, and perioperative details from patients who underwent laparoscopic and OLP between 1999 and 2006 were retrieved from our database and analyzed. Long-term results, including resume to full-time work, occurrence of incisional hernias, and incidence of exocrine and endocrine insufficiency also were evaluated. A total of 116 patients were included in the analysis; 43 (37.1%) were managed laparoscopically and 73 (62.9%) underwent the open procedure. There were no significant differences regarding clinical and pathological data. All of the resections attempted laparoscopically were completed. The rate of splenic preservation was significantly higher in the laparoscopic group (P = 0.0001). Postoperative outcomes were similar between the two groups. Longitudinal comparison between two time periods (1999-June 2004 vs. July 2004-2006) showed that pancreatic fistula and hospital stay significantly diminished over time in the laparoscopic group (P = 0.04 and P = 0.004, respectively). Median follow-up was 53 months. The incidence of exocrine insufficiency and incisional hernias was significantly higher after open resections (both P = 0.05). After hospital discharge, median time to resume full-time work was 6 weeks in the open group and 3 weeks after laparoscopic resections (P < 0.0001). Laparoscopy also resulted as an independent factor for an early resume to full-time activities in the multivariate analysis (P < 0.0001). Laparoscopic left pancreatectomy is a safe procedure for benign and borderline tumors, with similar perioperative outcomes compared with the open procedure. In the long term, the laparoscopic approach is likely to be superior thanks to a more rapid resume

    Clinical trial registration has become an important part of editorial policies of various biomedical journals, including a few physical therapy journals. However, the extent to which editorial boards enforce the need for trial registration varies across journals. The purpose of this study was to identify editorial policies and reporting of trial registration details in MEDLINE-indexed English-language physical therapy journals. This study was carried out using a cross-sectional design. Editorial policies on trial registration of MEDLINE-indexed member journals of the International Society of Physiotherapy Journal Editors (ISPJE) (Journal of Geriatric Physical Therapy, Journal of Hand Therapy, Journal of Neurologic Physical Therapy, Journal of Orthopaedic and Sports Physical Therapy, Journal of Physiotherapy [formerly Australian Journal of Physiotherapy], Journal of Science and Medicine in Sport, Manual Therapy, Physical Therapy, Physical Therapy in Sport, Physiotherapy, Physiotherapy Research International, Physiotherapy Theory and Practice, and Revista Brasileira de Fisioterapia) were reviewed in April 2013. Full texts of reports of clinical trials published in these journals between January 1, 2008, and December 31, 2012, were independently assessed for information on trial registration. Among the 13 journals, 8 recommended trial registration, and 6 emphasized prospective trial registration. As of April 2013, 4,618 articles were published between January 2008 and December 2012, of which 9% (417) were clinical trials and 29% (121/417) of these reported trial registration details. A positive trend in reporting of trial registration was observed from 2008 to 2012. The study was limited to MEDLINE-indexed ISPJE member journals. Editorial policies on trial registration of physical therapy journals and a rising trend toward reporting of trial registration details indicate a positive momentum toward trial registration. Physical therapy journal editors need to show

    Evaluation of scientific literature, promoting the delivery of evidence-based care, became the focus of a group of dental hygiene colleagues. The "Journal Study Club" (JSC) was established from this concept. JSC members discuss and evaluate professional issues utilizing research-based literature. Topics include patient care, public health/access to care, technology, modalities of treatment, and professional issues. For each topic, one member serves as a program facilitator researching the scientific literature on an agreed upon topic, chooses appropriate articles, and disseminates the articles to the members to read prior to meeting. Discussion at the study club event follows the format of examining literature content, relevance, significance, evidence accuracy, and application to clinical practice. This process supports dental Hygienists' commitment to life-long learning and the practice of evidence-based care, while providing a valuable venue for continuing dental hygiene competence and professional development.

    Full Text Available Systematic reviews of the effects of healthcare interventions frequently include non-randomized studies. These are subject to confounding and a range of other biases that are seldom considered in detail when synthesizing and interpreting the results. Our aims were to assess the reliability and usability of a new Cochrane risk of bias (RoB tool for non-randomized studies of interventions and to determine whether restricting analysis to studies with low or moderate RoB made a material difference to the results of the reviews.We selected two systematic reviews of population-based, controlled non-randomized studies of the relationship between the use of thiazolidinediones (TZDs and cyclooxygenase-2 (COX-2 inhibitors and major cardiovascular events. Two epidemiologists applied the Cochrane RoB tool and made assessments across the seven specified domains of bias for each of 37 component studies. Inter-rater agreement was measured using the weighted Kappa statistic. We grouped studies according to overall RoB and performed statistical pooling for (a all studies and (b only studies with low or moderate RoB. Kappa scores across the seven bias domains ranged from 0.50 to 1.0. In the COX-2 inhibitor review, two studies had low overall RoB, 14 had moderate RoB, and five had serious RoB. In the TZD review, six studies had low RoB, four had moderate RoB, four had serious RoB, and two had critical RoB. The pooled odds ratios for myocardial infarction, heart failure, and death for rosiglitazone versus pioglitazone remained significantly elevated when analyses were confined to studies with low or moderate RoB. However, the estimate for myocardial infarction declined from 1.14 (95% CI 1.07-1.24 to 1.06 (95% CI 0.99-1.13 when analysis was confined to studies with low RoB. Estimates of pooled relative risks of cardiovascular events with COX-2 inhibitors compared with no nonsteroidal anti-inflammatory drug changed little when analyses were confined to studies with

    2015-06-01

    Full Text Available This article reports the results of a study examining the state of data guidance provided to authors by 50 oncology journals. The purpose of the study was the identification of data practices addressed in the journals’ policies. While a number of studies have examined data sharing practices among researchers, little is known about how journals address data sharing. Thus, what was discovered through this study has practical implications for journal publishers, editors, and researchers. The findings indicate that journal publishers should provide more meaningful and comprehensive data guidance to prospective authors. More specifically, journal policies requiring data sharing, should direct researchers to relevant data repositories, and offer better metadata consultation to strengthen existing journal policies. By providing adequate guidance for authors, and helping investigators to meet data sharing mandates, scholarly journal publishers can play a vital role in advancing access to research data.

    Full Text Available Approximately 350 English-language journals in the interdisciplinary field of marine science are published. Two decades of steeply rising prices have forced the cancellation of journal subscriptions in this and all other scientific, technical and medical areas. Two groups of marine science titles, one of fifty titles, and one of fourteen are analyzed for price increases between 1997 and 2003. Within the larger context of escalating journal prices in all scientific fields, the marine science journals have increased in price approximately 71% during this period, while general science titles have increased 34%. Promising attempts to alleviate the situation must be expanded to avert the end result of a breakdown in scientific communication.

We determined whether study design of clinical research published in high-impact journals influences media coverage.We compared the incidence and amount of media coverage of RCTs with that of observational studies published in the top 7 medical journals between 1 January 2013 and 31 March 2013. We specifically assessed media coverage of the most rigorous RCTs, those with >1000 participants that reported 'hard' outcomes. There was no difference between RCTs and observational studies in coverage by major newspapers or news agencies, or in total number of news stories generated (all P>0.63. Large RCTs reporting 'hard' outcomes did not generate more news coverage than small RCTs that reported surrogate outcomes and observational studies (all P>0.32. RCTs were more likely than observational studies to attract a journal editorial (70% vs 46%, P = 0.003, but less likely to be the subject of a journal press release (17% vs 50%, P0.99, nor were they more likely to be the subject of a journal press release (14% vs 38%, P = 0.14.The design of clinical studies whose results are published in high-impact medical journals is not associated with the likelihood or amount of ensuing news coverage.

    Drugs are a frequent subject in the news media. Despite the existence of an important dynamic interplay between the print media, public opinion, and public policies, studies on these relationships are still scarce regarding the drug issue. The objective of this study is to understand the newsmaking process regarding drugs from the vantage point of Brazilian journalism professionals. Using qualitative research, semistructured interviews were conducted among an intentional sample of 22 professionals who write news stories and articles about drugs in nationwide news media. Interviewees mentioned illegality and crime as the main factors leading to the production of stories and articles. They claimed that by instilling fear among readers, newspapers and magazines tend to increase their audiences and/or sales. Most interviewees considered the coverage of drugs in Brazil as weak. Main problems reported include lack of knowledge on the subject, and not enough time to prepare the stories. It was concluded that the newsmaking process regarding drugs undergoes a series of interferences that compromise the content of the stories, therefore social strategies are needed in order to improve the quality of the material published in Brazil.

    Neurological sciences form a multidisciplinary field that produces a wide range of scientific journals. The aim of this study was to perform a scientometric analysis of neurological science journals in the 2006 Journal Citation Reports-Science Citation Index (JCR-SCI) edition. We study the three areas dedicated to neurological sciences (Neurosciences, Clinical Neurology and Neuroimaging) in the 2006 JCR-SCI edition. Bibliometric indicators used are: journals, articles, citations, impact factor (IF), immediacy index, half life and journals with the greatest IF in each specialty. We also perform a special analysis of Spanish neurological journals in JCR-SCI. In the area of Neurosciences we find a total of 200 journals, 27.157 articles, 1.109.784 citations and an average IF of 2,446, the greatest IF belonging to Annu Rev Neurosci (28,533) and Nat Rev Neurosci (23,054); Spanish journals: Neurocirugia and Acta Esp Psiquiatr. The area of Clinical Neurology contains 147 journals, 18.114 articles, 540.364 citations and an average IF of 1,848, the greatest IF belonging to Lancet Neurol (9,479) and Ann Neurol (8,051); Spanish journals: Neurologia and Rev Neurol. The area of Neuroimaging contains 13 journals, 1.747 articles, 49.210 citations and an average IF of 1,298, the greatest IF belonging to Neuroimage (5,559) and Hum Brain Mapp (4,888). We found out a broad representation of neurological journals from the 6,166 journals included in the 2006 JCR-SCI edition. Bibliometric characteristics differ in accordance to the clinical (Clinical Neurology) or experimental (Neurosciences) nature of the area. Even though bibliometric indicators for the four Spanish neurological journals have gradually improve over the previous 5 years, they are still proportionally ranked low in JCR-SCI. Due to significant limitations observed in the IF, we suggest conducting its analysis from a multidimensional bibliometric perspective, and always within its contextual research area.

    Full Text Available This study attempts to investigate the electronic journal reading behaviour of social scientists in Taiwan and Mainland China. The main purposes of the study are as follows: to explore the importance of e-journals amongst social scientists’ research; to explore the e-journal reading behaviour of Taiwanese and Chinese social scientists; to unearth factors affecting e-journal article reading thereby allowing comparisons to be made between the e-journal reading behaviour of social scientists in Taiwan and Mainland China. Three surveys were carried out at ChengChi University in Taiwan, and Wuhan University and Nanjing University in Mainland China during 2012. The target population was social science faculty members and graduate students of the three universities. Three questionnaire surveys were conducted during January toApril 2012, with a total of 668 valid questionnaire responses collected. Analysis of reading e-journal critical incident articles showed that 46.7% were in Chinese and 53.3% in English. Each social scientist in Taiwan and Mainland China read on average 307 e-journal articles and spent about 380 hours annually reading e-journals; they read e-journals mainly for research purposes and the writing of papers. Information regarding the e-journal reading environments, reading methods, reading strategies and reading consequences of social scientists in Taiwan and Mainland China were collected and analysed. In this study four types of e-journal reading behaviour of social scientists in Taiwan and Mainland China are shown, namely; screen browsing; screen based-reading, print reading, and screen-based collocating reading. E-journal reading behavior of social scientists in Taiwan and Mainland China are studied and the study also illustrates some difference of e-journal reading behaviour between Taiwanese and Chinese social scientists. pp. 26-43

    The debate about the value of biomedical publications led to recommendations for improving reporting quality. It is unclear to what extent these recommendations have been endorsed by journals. We analyzed whether specific recommendations were included in author instructions, which journal characteristics were associated with their endorsement, how endorsement of the domains changed and whether endorsement was associated with change of impact factor between 2010 and 2015. We considered two study samples consisting of "Hematology" and "Oncology" journals of the Journal Citation Report 2008 and 2014, respectively. We extracted information regarding endorsement of the (1) recommendations of the International Committee of Medical Journal Editors, of (2) reporting guidelines, (3) requirement for trial registration and (4) disclosure of conflicts of interest. Data extraction was done by reading the author instructions before conducting a text search with keywords. We calculated a global generalized linear mixed effects model for endorsement of each of the four domains followed by separate multivariable logistic regression models and a longitudinal analysis. We defined endorsement as the author instructions saying that they approve the use of the recommendations. In 2015, the ICMJE recommendations were mentioned in author instructions of 156 journals (67.5%). CONSORT was referred to by 77 journals (33.3%); MOOSE, PRISMA, STARD and STROBE were referred to by less than 15% of journals. There were 99 journals (42.9%) that recommended or required trial registration, 211 (91.3%) required authors to disclose conflicts of interest. Journal impact factor, journal start year and geographical region were positively associated with endorsement of any of the four domains. The overall endorsement of all domains increased between 2010 and 2015. The endorsement of any domain in 2010 seemed to be associated with an increased impact factor in 2014. Hematology and oncology journals endorse

    Editors have a responsibility to retract seriously flawed articles from their journals. However, there appears to be little consistency in journals' policies or procedures for this. In a qualitative study, we therefore interviewed editors of science journals using semi-structured interviews to investigate their experience of retracting articles. We identified potential barriers to retraction, difficulties in the process and also sources of support and encouragement. Our findings have been used as the basis for guidelines developed by the Committee on Publication Ethics.

    Full Text Available This study reports on research that examined DEST data from 14 Australian universities to identify the diversity of journal outlets in the information systems (IS area. Across a total of 60 years of academic publishing output, 1449 journal articles were evaluated to identify 649 different journals in which IS-related articles were published. The most popular journals used by Australian academics to publish IS-related articles were the Lecture Notes in Computer Science (N=94 in the computer science area, with the Australasian Journal of Information Systems (N=25 being the most popular journal in the pure and business IS sphere. The study also examined publishing output against a set of 50 previously highly rated IS journals and concluded that the average annual publication of articles in these highly rated journals occurred at a very low rate. The research appears to be one of the first studies to use historical DEST data to report journal diversity in the Australian IS-sphere.

    The objective of this article was to record reporting characteristics related to study quality of research published in major specialty dental journals with the highest impact factor (Journal of Endodontics, Journal of Oral and Maxillofacial Surgery, American Journal of Orthodontics and Dentofacial Orthopedics; Pediatric Dentistry, Journal of Clinical Periodontology, and International Journal of Prosthetic Dentistry). The included articles were classified into the following 3 broad subject categories: (1) cross-sectional (snap-shot), (2) observational, and (3) interventional. Multinomial logistic regression was conducted for effect estimation using the journal as the response and randomization, sample calculation, confounding discussed, multivariate analysis, effect measurement, and confidence intervals as the explanatory variables. The results showed that cross-sectional studies were the dominant design (55%), whereas observational investigations accounted for 13%, and interventions/clinical trials for 32%. Reporting on quality characteristics was low for all variables: random allocation (15%), sample size calculation (7%), confounding issues/possible confounders (38%), effect measurements (16%), and multivariate analysis (21%). Eighty-four percent of the published articles reported a statistically significant main finding and only 13% presented confidence intervals. The Journal of Clinical Periodontology showed the highest probability of including quality characteristics in reporting results among all dental journals. Copyright © 2011 Elsevier Inc.

  19. Misalignment in Gas Foil Journal Bearings: An Experimental Study

    Howard, Samuel A.

    2008-01-01

    As gas foil journal bearings become more prevalent in production machines, such as small gas turbine propulsion systems and microturbines, system-level performance issues must be identified and quantified in order to provide for successful design practices. Several examples of system-level design parameters that are not fully understood in foil bearing systems are thermal management schemes, alignment requirements, balance requirements, thrust load balancing, and others. In order to address some of these deficiencies and begin to develop guidelines, this paper presents a preliminary experimental investigation of the misalignment tolerance of gas foil journal bearing systems. Using a notional gas foil bearing supported rotor and a laser-based shaft alignment system, increasing levels of misalignment are imparted to the bearing supports while monitoring temperature at the bearing edges. The amount of misalignment that induces bearing failure is identified and compared to other conventional bearing types such as cylindrical roller bearings and angular contact ball bearings. Additionally, the dynamic response of the rotor indicates that the gas foil bearing force coefficients may be affected by misalignment.

    Aim To explore immunoregulatory and anti-inflammatory pathways specifically targeted by a subcutaneous anti-TNFαdrug—adalimumab—which might be relevant for controlling refractory uveitis. Design Non-randomized pilot intervention study on the effects of adalimumab on Treg populations and plasma VEGF levels in refractory uveitis patients. Inflammatory and immunological parameters were measured in 12 patients before therapy, and 1 and 6 months after therapy, and analyzed in the context of ophthalmological outcomes. The results were compared with those obtained in 10 systemic prednisone-treated uveitis patients. Results After 1 month of treatment, all patients responded, with 67% of adalimumab group and 80% of the corticosteroid group achieving inactivity (P=0.5). Unlike steroid-treated patients, a significant increase in T-regulatory CD4+ CD25high Foxp3+ CD127− cells was observed in adalimumab patients after 1 month of treatment, and maintained after 6 months (P=0.003). A significant adalimumab-specific drop in plasma VEGF was observed after 1 and 6 months of treatment (P=0.019). In every single patient, Tregs but not VEGF correlated with disease activity. Conclusions In refractory uveitis patients treated with adalimumab, clinical efficacy may be mediated through upregulation of Tregs in addition to modulation of VEGF-mediated inflammatory pathways. These biological properties, which were not observed in patients treated with corticosteroids, may reflect the specificity of TNF-αtargeting. PMID:22222264

    Directory of Open Access Journals (Sweden)

    Liane Rothenberger

    2011-06-01

    Full Text Available Is journalism studies a sub-domain of communication studies, adistinct discipline, a multidisciplinary merger or a transdisciplinary endeavour? This question is discussed by analyzing the 2008 and2009 volumes of seven academic journals focusing on journalismresearch. The sample includes 349 articles published in BrazilianJournalism Research, Ecquid Novi, Journalism & CommunicationMonographs, Journalism & Mass Communication Quarterly, PacificJournalism Review, Journalism Studies, or Journalism: Theory,Practice and Criticism. Overall, the findings reveal that journalismresearch mainly applies theoretical approaches and empiricalmethods deriving from other disciplines, particularly sociology, psychology or cultural studies. In many countries, however, journalism studies has reached a comparatively high level of institutionalization indicated by the large number of specific schools, professorships, professional associations and respective academic journals. In conclusion, we argue that journalism studies is a sub-domain of communication studies, which integrates andtranscends various disciplines aiming to become one of the axialsubjects of the 21st century.

    Nuredini, K.; Peters, I.

    2016-07-01

    We present a case study of articles published in 30 journals from Economics and Business Studies (EBS) by using social media metrics from Altmetric.com. Our results confirm that altmetric information is significantly better present for recent articles. The Top 3 most used altmetric sources in EBS-journals are Mendeley, Twitter, and News. Low but positive correlations (r=0.2991) are identified between citation counts and Altmetric Scores on article level but they increase on journal level (r=0.614). However, articles from highly cited journals do neither receive high online attention nor are they better represented on social media. (Author)

    Krakow, Barry; McIver, Natalia D; Ulibarri, Victor A; Nadorff, Michael R

    2017-01-01

    Purpose Emerging evidence shows that positive airway pressure (PAP) treatment of obstructive sleep apnea (OSA) and upper airway resistance syndrome (UARS) in chronic insomnia patients (proposed “complex insomnia” disorder) leads to substantial decreases in insomnia severity. Although continuous PAP (CPAP) is the pressure mode most widely researched, intolerance to fixed pressurized air is rarely investigated or described in comorbidity patients. This retrospective study examined dual pressure, autoadjusting PAP modes in chronic, complex insomnia disorder patients. Patients and methods Chronic insomnia disorder patients (mean [SD] insomnia severity index [ISI] =19.11 [3.34]) objectively diagnosed with OSA or UARS and using either autobilevel PAP device or adaptive servoventilation (ASV) device after failing CPAP therapy (frequently due to intolerance to pressurized air, poor outcomes, or emergence of CSA) were divided into PAP users (≥20 h/wk) and partial users (insomnia patients, PAP users (n=246) averaged 6.10 (1.78) nightly hours and 42.71 (12.48) weekly hours and partial users (n=56) averaged 1.67 (0.76) nightly hours and 11.70 (5.31) weekly hours. For mean (SD) decreases in total ISI scores, a significant (group × time) interaction was observed (F[1,300]=13.566; Pinsomnia symptoms (r=−0.256, PInsomnia severity significantly decreased in patients using autoadjusting PAP devices, but the study design restricts interpretation to an association. Future research must elucidate the interaction between insomnia and OSA/UARS as well as the adverse influence of pressure intolerance on PAP adaptation in complex insomnia patients. Randomized controlled studies must determine whether advanced PAP modes provide benefits over standard CPAP modes in these comorbidity patients. PMID:28331381

    2017-07-01

    Medical error is common in crises, and the majority of observed errors are nontechnical in nature. The long-term impact of teaching crisis nontechnical skills to residents has not been evaluated. The objective of this study was to determine the effect of simulation-based teaching of crisis nontechnical skills compared to controls one year after initial teaching. This was a prospective study using both historical controls and a before-and-after methodology to evaluate the effect of a high-fidelity simulation curriculum that used crisis resource management principles to teach nontechnical skills. Postgraduate year 2 and 3 residents were invited to take part in a prospective training course over 2 years. The primary outcome was leader performance evaluated by expert raters using the previously validated 7-point Ottawa Global Rating Scale. Overall, 23 residents performed 30 simulations over the 2 years with the intervention group of 7 residents being assessed in both years. After adjustment, the postgraduate year 3 intervention group who received training the previous year had significantly higher overall performance scores than all postgraduate year 2 scores (1.09 95% confidence interval 0.70-1.47, P < .001) and the historical postgraduate year 3 cohort who received no prior training (1.20, 95% confidence interval 0.37-2.03, P = .005). There was no decay of skills noted over the course of the study. Postgraduate year 3 residents who had prior training had significantly improved crisis performance compared to historical postgraduate year 3 controls and untrained postgraduate year 2 residents. There were no significant differences between the crisis performance of postgraduate year 2 residents and the untrained postgraduate year 3 controls. This confirms the beneficial effect and long-term retention after crisis nontechnical skill training. Copyright © 2016 Elsevier Inc. All rights reserved.

    Participation in health studies may be inversely associated with employment and stress. We investigated whether employment, perceived stress, work-related stress, and family caregiving were related to participation in a longitudinal US community-based health study of black and white men and women aged ≥45 years. Prevalence ratios and confidence intervals were estimated for completion of the second stage (S2) of a two-stage enrollment process by employment (status, type), and stress (perceived stress, work-related stress, caregiving), adjusting for age, sex, race, region, income, and education. Eligibility and consent for a follow-up occupational survey were similarly evaluated. Wage- but not self-employed participants were less likely than the unemployed to complete S2. Among the employed, S2 completion did not vary by stress; however, family caregivers with a short time burden of care (<2 hour/d) were more likely to complete S2, compared to noncaregivers. Eligibility and participation in the follow-up occupational survey were higher among those employed (vs. unemployed) at enrollment but were not associated with enrollment stress levels. Limited evidence of selection bias was seen by employment and stress within a large US community-based cohort, but findings suggest the need for enrollment procedures to consider possible barriers to participation among wage-employed individuals.

The surgical procedure involved making a 1.7 mm temporal corneal incision, exposing an approximately 15° opening in the inner wall of Schlemm’s canal (nasal side using a Trabectome with a gonioscope, and inserting a 5-0 nylon suture rounded at the tip into Schlemm’s canal opened via the anterior chamber. The suture was then threaded around Schlemm’s canal, and the tip of the suture that emerged on the other side was then advanced through the opening to make a circumferential incision. Intraocular pressure (IOP, number of anti-glaucoma medications used, complications, and the surgery completion rate were prospectively studied.Results: Mean IOP, which was 19.4 mmHg at baseline, showed a significant decrease at each of the monthly observation points, reaching 13.8 mmHg at 6 months after surgery (P=0.0004, paired t-test. The mean number of anti-glaucoma medications decreased from 3.2 at baseline to 1.1 at 6 months after surgery. IOP spikes ≥30 mmHg were seen in 25% of patients, but there were no other serious complications and the surgery completion rate was 92%.Conclusion: The 360°LOT ab interno procedure preserves the conjunctiva and sclera, and has a high surgery completion rate when using the anterior chamber approach, and could therefore be an effective short-term treatment of open-angle glaucoma.Keywords: non-penetrating surgery, intraocular pressure, Schlemm’s canal, corneal incision, Trabectome

    Observational evidence suggests that dietary glycemic load may be one environmental factor contributing to the variation in acne prevalence worldwide. To investigate the effect of a low glycemic load (LGL) diet on endocrine aspects of acne vulgaris, 12 male acne sufferers (17.0 +/- 0.4 years) completed a parallel, controlled feeding trial involving a 7-day admission to a housing facility. Subjects consumed either an LGL diet (n = 7; 25% energy from protein and 45% from carbohydrates) or a high glycemic load (HGL) diet (n = 5; 15% energy from protein, 55% energy from carbohydrate). Study outcomes included changes in the homeostasis model assessment of insulin resistance (HOMA-IR), sex hormone binding globulin (SHBG), free androgen index (FAI), insulin-like growth factor-I (IGF-I), and its binding proteins (IGFBP-I and IGFBP-3). Changes in HOMA-IR were significantly different between groups at day 7 (-0.57 for LGL vs. 0.14 for HGL, p = 0.03). SHBG levels decreased significantly from baseline in the HGL group (p = 0.03), while IGFBP-I and IGFBP-3 significantly increased (p = 0.03 and 0.03, respectively) in the LGL group. These results suggest that increases in dietary glycemic load may augment the biological activity of sex hormones and IGF-I, suggesting that these diets may aggravate potential factors involved in acne development.

    Full Text Available Background: Home-based specialist palliative care services are developed to meet the needs of the patients in advanced stage of cancer at home with physical symptoms and distress. Specialist home care services are intended to improve symptom control and quality of life, enable patients to stay at home, and avoid unnecessary hospital admission. Materials and Methods: Total 690 new cases registered under home-based palliative care service in the year 2012 were prospectively studied to assess the impact of specialist home-based services using Edmonton symptom assessment scale (ESAS and other parameters. Results: Out of the 690 registered cases, 506 patients received home-based palliative care. 50.98% patients were cared for at home, 28.85% patients needed hospice referral and 20.15% patients needed brief period of hospitalization. All patients receiving specialist home care had good relief of physical symptoms ( P < 0.005. 83.2% patients received out of hours care (OOH through liaising with local general practitioners; 42.68% received home based bereavement care and 91.66% had good bereavement outcomes. Conclusion: Specialist home-based palliative care improved symptom control, health-related communication and psychosocial support. It promoted increased number of home-based death, appropriate and early hospice referral, and averted needless hospitalization. It improved bereavement outcomes, and caregiver satisfaction.

    To determine whether the quality of press releases issued by medical journals can influence the quality of associated newspaper stories. Retrospective cohort study of medical journal press releases and associated news stories. We reviewed consecutive issues (going backwards from January 2009) of five major medical journals (Annals of Internal Medicine, BMJ, Journal of the National Cancer Institute, JAMA, and New England Journal of Medicine) to identify the first 100 original research articles with quantifiable outcomes and that had generated any newspaper coverage (unique stories ≥100 words long). We identified 759 associated newspaper stories using Lexis Nexis and Factiva searches, and 68 journal press releases using Eurekalert and journal website searches. Two independent research assistants assessed the quality of journal articles, press releases, and a stratified random sample of associated newspaper stories (n=343) by using a structured coding scheme for the presence of specific quality measures: basic study facts, quantification of the main result, harms, and limitations. Proportion of newspaper stories with specific quality measures (adjusted for whether the quality measure was present in the journal article's abstract or editor note). We recorded a median of three newspaper stories per journal article (range 1-72). Of 343 stories analysed, 71% reported on articles for which medical journals had issued press releases. 9% of stories quantified the main result with absolute risks when this information was not in the press release, 53% did so when it was in the press release (relative risk 6.0, 95% confidence interval 2.3 to 15.4), and 20% when no press release was issued (2.2, 0.83 to 6.1). 133 (39%) stories reported on research describing beneficial interventions. 24% mentioned harms (or specifically declared no harms) when harms were not mentioned in the press release, 68% when mentioned in the press release (2.8, 1.1 to 7.4), and 36% when no press release

    Full Text Available Background and Aim: Widespread use of imipenem in intensive care units (ICUs in India has led to the development of numerous carbapenemase-producing strains of pathogens. The altered pathophysiological state in critically ill patients could lead to subtherapeutic antibiotic levels. Hence, the aim of this study was to investigate the variability in the pharmacokinetic and pharmacodynamic profile of imipenem in critically ill patients admitted to an ICU in India. Materials and Methods: Plasma concentration of imipenem was determined in critically ill patients using high performance liquid chromatography, at different time points, by grouping them according to their locus of infection. The elimination half-life (t΍ and volume of distribution (V d values were also computed. The patients with imipenem trough concentration values below the minimum inhibitory concentration (MIC and 5 times the MIC for the isolated pathogen were determined. Results: The difference in the plasma imipenem concentration between the gastrointestinal and the nongastrointestinal groups was significant at 2 h (P = 0.015 following drug dosing; while the difference was significant between the skin/cellulitis and nonskin/cellulitus groups at 2 h (P = 0.008, after drug dosing. The imipenem levels were above the MIC and 5 times the MIC for the isolated organism in 96.67% and 50% of the patients, respectively. Conclusions: The pharmacokinetic profile of imipenem does not vary according to the locus of an infection in critically ill patients. Imipenem, 3 g/day intermittent dosing, maintains a plasma concentration which is adequate to treat most infections encountered in patients admitted to an ICU. However, a change in the dosing regimen is suggested for patients infected with organisms having MIC values above 4 mg/L.

    To determine the parameters that may help the clinicians decide the best suitable treatment method for the pregnant women with symptomatic hydronephrosis which will be based on the easily accessible laboratory tests, monitoring methods and clinical symptoms. Digital data and documents of 246 pregnant women with symptomatic hydronephrosis who were hospitalized in our clinic between the dates of January 2011 and January 2016 were retrospectively evaluated. All patients were statistically evaluated in terms of age, symptomatic maximal anterior-posterior diameter of the renal pelvis (MADP), parity, C-reactive protein (CRP) level, white blood cell count (WBC), presence of pyuria, growth of urine culture, fever, serum urine and creatinine levels, visual analog scale (VAS) score of pre- and post-therapy and threatened preterm labor. The study includes a total of 211 pregnant women with symptomatic hydronephrosis. In the second and third trimester groups, the surgical treatment group statistically provided higher levels of CRP, WBC and VAS. Mean MADP in the second trimester of the conservative and surgical groups where symptomatic hydronephrosis was on the right side was 16.67 ± 4.67 and 28.68 ± 7.70 mm, respectively. Mean MADP in the third trimester group of the conservative and surgical groups where symptomatic hydronephrosis was on the right side was 16.96 ± 5.96 and 28.85 ± 7.64 mm, respectively. In patients with symptomatic pregnancy hydronephrosis, the likelihood of surgical treatment for CRP levels, WBC counts and VAS is high.

    BACKGROUND: Heart rate variability refers to the beat-to-beat alteration in heart rate. It is usually a slight periodic variation of R-R intervals. Much information of autonomic nerve system balance can be obtained by measuring the heart rate variability of patients. It remains to be shown whether heart rate variability can be used as an index for determining the severity of insomnia and cerebral infarction. OBJECTIVE: This study aimed to analyze the correlation for each frequency spectrum parameter of heart rate variability with an insomnia index, as well as the degree of neurological defects in patients with simple cerebral infarction and cerebral infarction complicated by insomnia. The goal was to verify the feasibility of frequency spectrum parameters for heart rate variability as a marker for insomnia and cerebral infarction. DESIGN: A case-control observation. SETTING: Department of Neurology, First Hospital Affiliated to China Medical University. PARTICIPANTS: Sixty inpatients, and/or outpatients, with cerebral infarction were admitted to the 202 Hospital of Chinese PLA between December 2005 and October 2006, confirmed by CT, and recruited to the study. According to the insomnia condition (insomnia is defined by a Pittsburgh Sleep Quality Index score > 7), the patients were assigned to a simple cerebral infarction group and a cerebral infarction complicated by insomnia group, with 30 subjects in each group. Thirty additional subjects, who concurrently received ex-aminations and were confirmed to not suffer from cerebral infarction and insomnia, were recruited into the control group. Written informed consent was obtained from each subject for laboratory specimens. The pro-tocol was approved by the Hospital's Ethics Committee. METHODS: Following admission, each subject's neurological impairment was assessed with the National Institutes of Health Stroke Scale and Pittsburgh Sleep Quality Index. Heart rate variability of each subject was measured with an

    A qualitative study of the impact of electronic journals on the information behavior of academics at Catalan universities shows that academics now read more, and more widely. However, their reading is becoming more superficial; they are compelled to improve their discrimination skills in order to decide what to read in more depth. The electronic accessibility of journals means that academics now make fewer library visits. Web browsing and TOC e-mail alerts are replacing physical browsing, and...

    This report describes the 12-month outcomes of the a prospective, multicenter, nonrandomized post-approval study of the MitraClip therapy in Europe (ACCESS-EU postapproval study of MitraClip therapy) with respect to preprocedural left ventricular ejection fraction (LVEF). Transcatheter deployment of the MitraClip device may be considered for patients who are not suitable for conventional surgery. A total of 567 patients with significant mitral regurgitation (MR) underwent MitraClip therapy. Of those, 393 had functional MR (FMR) and were subdivided by preprocedural LVEF (A: 10% to 20%, B: >20% to 30%, C: >30% to 40%, D: >40%). Procedural safety and efficacy and treatment outcomes including MR grade, New York Heart Association (NYHA) functional class, 6-minute walk test, and the Minnesota Living with Heart Failure Questionnaire were analyzed at baseline, 30 days, and 12 months. Baseline mean logistic EuroSCORE was 25 ± 19; 87% of patients were in NYHA classes III or IV (A: 96%, B: 83%, C: 90%, D: 86%). There was no incidence of death or stroke intraprocedurally. Eleven patients died within 30 days with no differences among subgroups. Kaplan-Meier survival at 12 months was 81.8% (A: 71%, B: 79%, C: 87%, D: 86%). There was a significant improvement in MR severity at 30 days and 12 months (p FMR. In conclusion, the low rates of hospital mortality and adverse events in patients with FMR-even in patients with severely reduced LVEF-provide additional evidence of substantial benefits after MitraClip implantation.

    To assess the relatedness of journal content to paid advertisements published in the journal. The case-control study was performed on a convenience sample of 7 journals subscribed by Central Medical Library in Moscow--4 international (American Journal of Hypertension, British Journal of General Practice, The Lancet, and New England Journal of Medicine) and 3 Russian peer reviewed journals (Terapevticheskii Arkhiv, Khirurgiia, and Voeno-Meditsinskii Zhurnal). In each issue containing a paid advertisement, classifieds excluded, we searched for articles related to the advertised product and compared this issue with a control issue - the next or a later issue without this advertisement. In American Journal of Hypertension (33 issues from 2002-2004) 94 placements of advertisements were found, 7 of which were closely related to the article topic in the same issue (7/94) vs 2/66 in the control issue. The odds ratio (OR) and 95% confidence interval (CI) for advertisements to be accompanied by related articles was OR, 2.6; 95%CI, 0.5-13). In British Journal of General Practice (27 issues from 2003-2005) there were 7/63 advertisements related to the article topic vs 0/28 in the control issue (OR, 7.2; 95% CI, 1.3 to 44). In The Lancet (49 issues from 2004) there were 8/162 advertisements related to the article topic vs 8/104 in the control issue (OR, 0.6; 95% CI, 0.3-1.5). In New England Journal of Medicine (37 issues from 2004) there were 12/81 advertisements related to the article topic vs 8/75 in the control issue (OR, 1.5; 95% CI, 0.56-3.79). In Terapevticheskii Arkhiv (10 issues from 2004) there were 38/93 advertisements related to the article topic vs 1/83 in the control issue (OR, 56.66; 95% CI, 4.4-253). In Khirurgiia (25 issues from 2003-2005) there were 3/83 advertisements related to the article topic vs 0/70 in the control issue (OR, 2.7; 95% CI, 0.3-26). In Voeno-Meditsinskii Zhurnal (33 issues from 2003-2005) there were 17/31 advertisements related to the

    Although qualitative studies have increased since the 1990s, some reports note that relatively few influential journals published them up until 2000. This study critically reviewed the characteristics of qualitative studies published in top tier medical journals since 2000. We assessed full texts of qualitative studies published between 2000 and 2004 in the Annals of Internal Medicine, BMJ, JAMA, Lancet, and New England Journal of Medicine. We found 80 qualitative studies, of which 73 (91%) were published in BMJ. Only 10 studies (13%) combined qualitative and quantitative methods. Sixty-two studies (78%) used only one method of data collection. Interviews dominated the choice of data collection. The median sample size was 36 (range: 9-383). Thirty-three studies (41%) did not specify the type of analysis used but rather described the analytic process in detail. The rest indicated the mode of data analysis, in which the most prevalent methods were the constant comparative method (23%) and the grounded theory approach (22%). Qualitative data analysis software was used by 33 studies (41%). Among influential journals of general medicine, only BMJ consistently published an average of 15 qualitative study reports between 2000 and 2004. These findings lend insight into what qualities and characteristics make a qualitative study worthy of consideration to be published in an influential journal, primarily BMJ.

    Full Text Available This paper presents the findings of a bibliometric study of Journal of Intellectual Property Rights. A total of 332 articles carrying 1,541 journal citations during the period of 2002-2010 were analyzed. 471 authors contributed articles during the nine years. Due to the absolute domination of solo contributions, the visibility of collaborative contribution was found remarkably less. About one third of the total publications received citations, more than half of the cited articles carried just 1 citation, one fourth got 2 citations, and the rest received citations between 3 to 9 times. The average number of citations against all published articles was found to be 0.66 per article. Moreover, it was discovered that self-citations among authors constituted 22.01% of the total cited scholarly papers. The top five cited journals were Journal of Intellectual Property Rights, European Intellectual Property Review, Research Policy, World Patent Information, Trademark Reporter, and Current Science.

    Full Text Available The purpose of this paper is multifold.Key aspects discussed include exploring the extent of theory discussion and progression in social work journals for the year 2004; discussing the necessity of theory in social work research and practice; reviewing previous research literature regarding evaluation of theory discussion and progression; proposing criteria for defining theory in social work journals; and presenting findings from the current study concerning theory discussion and progression in social work journals. Results: Of the 1,168 articles reviewed from 37 journals, 71 (approximately 6% met the criteria for theory development with empirical base. Thus, a minimal number of articles (3 out of 71 or 4.2% evaluated, based on the criteria in the theory quality scale (Table 1, received high quality ratings. Conclusion: Based on the results yielded by the analysis, we assert that social workers need to make a conscious effort to include theory in practice decisions.

    Full Text Available In this article, which reports the second part of a two-part study of the use of electronic journals by researchers in two French research institutions, we attempt to explain the integration of the use of electronic journals in the scientists' information habits, going beyond usage analysis. First, we describe how the development of electronic journals use follows a three-phase innovation process - research-development, first uses, and technical acculturation. Then, we attempt to find more significant explanatory factors, and emphasis is placed on the wider context of information activity. Three main information activity types are outlined - marginal, parallel, and integrated. Each of these types corresponds to a particular attitude towards scientific information and to different levels of electronic journal use.

    Full Text Available Background. The Journal Citation Reports journal impact factors (JIFs are widely used to rank and evaluate journals, standing as a proxy for the relative importance of a journal within its field. However, numerous criticisms have been made of use of a JIF to evaluate importance. This problem is exacerbated when the use of JIFs is extended to evaluate not only the journals, but the papers therein. The purpose of this study was therefore to investigate the relationship between the number of citations and journal IF for identical articles published simultaneously in multiple journals. Methods. Eligible articles were consensus research reporting statements listed on the EQUATOR Network website that were published simultaneously in three or more journals. The correlation between the citation count for each article and the median journal JIF over the published period, and between the citation count and number of article accesses was calculated for each reporting statement. Results. Nine research reporting statements were included in this analysis, representing 85 articles published across 58 journals in biomedicine. The number of citations was strongly correlated to the JIF for six of the nine reporting guidelines, with moderate correlation shown for the remaining three guidelines (median r = 0.66, 95% CI [0.45–0.90]. There was also a strong positive correlation between the number of citations and the number of article accesses (median r = 0.71, 95% CI [0.5–0.8], although the number of data points for this analysis were limited. When adjusted for the individual reporting guidelines, each logarithm unit of JIF predicted a median increase of 0.8 logarithm units of citation counts (95% CI [−0.4–5.2], and each logarithm unit of article accesses predicted a median increase of 0.1 logarithm units of citation counts (95% CI [−0.9–1.4]. This model explained 26% of the variance in citations (median adjusted r2 = 0.26, range 0.18–1.0. Conclusion

    Full Text Available The scope of the present study was to contrast publication rates and particularities of original scientific articles related to medical PhD theses defended between 2009 and 2013 from one developing country (Romania and two developed countries (France and the United Kingdom within the European Union. A sample from each of the three countries was evaluated and then compared based on the journal type (national/international, time span between two consecutive articles from the same thesis, number of articles, journal impact factor and journal rank. The results of our quantitative analysis suggest that the majority of Romanian articles were published in Romanian journals, while French and the United Kingdom articles were published in greater proportions in journals outside the borders of their own country. The time span between two consecutive articles from the same thesis was similar for the three groups. Even though articles from Romanian theses were significantly more numerous than in those from France or the United Kingdom, they were published in less cited journals, according to their impact factor. Furthermore, most of the Romanian articles were published in the bottom half of the journals’ ranking, while the majority of articles from France or the United Kingdom were published in the top half of the ranking.

    To adequately translate research into practice, research results should be reported in a way that is useful to practicing clinicians and policymakers. Based on evidence from systematic reviews, the implementation of reporting guidelines, such as CONSORT for randomized controlled trials, may improve the quality of research reporting. We assessed the endorsement of reporting guidelines in rheumatology journals. We analyzed guidelines for authors of all (n = 28) journals indexed in the "Rheumatology" Subject Category of the Journal Citation Reports published in 2012. Journal websites were reviewed for information relevant to reporting guidelines. Out of 28 indexed journals, only about a third (n = 10) endorsed 1 or more reporting guidelines, most commonly CONSORT. General editorial policies, such as those from the International Committee of Medical Journal editors (ICMJE), were endorsed by 19 journals (all 10 journals with and 9 out of 18 without reporting guidelines). Two rheumatology journals introduced specific reporting guidelines about economic studies and genetic association studies. The endorsement of reporting guidelines is low in rheumatology journals. To continue to serve their research community, rheumatology journals should provide the platform for the discussion on most relevant reporting guidelines and adopt them as a group, especially those specific for rheumatology research. Coordinated action of journals and other stakeholders in rheumatology research in the promotion of accurate and transparent reporting of health research studies would be an important part of knowledge translation into practice and well-being of rheumatology patients.

    We study the hypothesis of information panspermia assigned recently among possible solutions of the Fermi paradox ("where are the aliens?"). It suggests that the expenses of alien signaling can be significantly reduced, if their messages contained compressed information. To this end we consider universal compression and decoding mechanisms ( e.g. the Lempel-Ziv-Welch algorithm) that can reveal non-random structures in compressed bit strings. The efficiency of the Kolmogorov stochasticity parameter for detection of non-randomness is illustrated, along with the Zipf's law. The universality of these methods, i.e. independence from data details, can be principal in searching for intelligent messages.

    Globally, efforts aimed at the prevention of childhood obesity have led to the implementation of a range of school-based interventions. This study assessed whether augmenting physical activity (PA) within the school setting resulted in increased daily PA and decreased overweight/obesity levels in 6-9-year-old children. Across the first to third primary school years, PA of 84 girls and 92 boys was objectively monitored five times (each for seven successive days) using Yamax pedometer (step counts) and Caltrac accelerometer (activity energy expenditure AEE - kcal/kg per day). Four schools were selected to participate in the research (2 intervention, 2 controls), comprising intervention (43 girls, 45 boys) and control children (41 girls, 47 boys). The study was non-randomized and the intervention schools were selected on the basis of existing PA-conducive environment. Analyses of variance (ANOVA) for repeated measures examined the PA programme and gender effects on the step counts and AEE. Logistic regression (Enter method) determined the obesity and overweight occurrence prospect over the course of implementation of the PA intervention. There was a significant increase of school-based PA during schooldays in intervention children (from ≈ 1718 to ≈ 3247 steps per day; and from 2.1 to ≈ 3.6 Kcal/Kg per day) in comparison with the control children. Increased school-based PA of intervention children during schooldays contributed to them achieving >10,500 steps and >10.5 Kcal/Kg per school day across the 2 years of the study, and resulted in a stop of the decline in PA levels that is known to be associated with the increasing age of children. Increased school-based PA had also positive impact on leisure time PA of schooldays and on PA at weekends of intervention children. One year after the start of the PA intervention, the odds of being overweight or obese in the intervention children was almost three times lower than that of control children (p

  7. How journal rankings can suppress interdisciplinarity. The case of innovation studies in business and management

    2011-01-01

    While interdisciplinary research (IDR) is valued as a means of encouraging scientific breakthroughs, innovation and socially relevant science, it is also widely perceived as being at a disadvantage in research evaluations. Various qualitative studies have provided evidence that peer review tends to be biased against IDR. However, quantitative investigations on this claim have been few and inconclusive. This paper provides new quantitative evidence of how journal rankings can disadvantage IDR in evaluation. Using publication data it compares the degree of interdisciplinarity and the research performance of innovation studies units with business and management schools in the UK. The paper uses various mappings and metrics to show that innovation studies units are consistently more interdisciplinary than business and management schools. It shows that the top journals in the Association of Business Schools' rankings span a less diverse set of disciplines than lower ranked journals, and that this bias results in a...

    2010-01-01

    The objective of this study was to examine the article production on psychosis from the main spanish journals of psychology and psychiatry, as well as to make comparisons among them. 16 journals of psychology and 5 of psychiatry were selected and a period of revision of four years settled down (2003-2006). The sample was constituted by 183 articles. For the comparison of the journals four index were used: proportion of articles on psychosis in relation to the total of generated articles; used type of methodology; used type of sample; and aspect of the psychosis in whose investigation it is centered. The results show that little is investigated, that most of the studies is theoretical or ex- post facto, that more the frequently studied subjects are those with psychosis and that the taken care of aspects more are related to the etiology and the treatment of the disease.

    To analyze the scientific activity and the production of information of the Farmacia Hospitalaria journal as the Spanish scientific publication of reference in the pharmaceutical area. Transversal descriptive study of the results obtained from the bibliometric analysis of the articles published in the journal. Data was obtained from direct queries and Internet access to the scientific literature contained in the electronic version of the journal during the 2004-2012 period. During the period studied 756 articles were published. The number of original articles was 258 (34.12%) with a productivity index of 2.40. The number of institutions identified with published articles was 246. The predominant language was Spanish with 733 (96.96%) articles. We counted 1828 keywords, of which 527 (28.83%) coincided with MeSH. The median calculation of the obsolescence of quoted references was 10, and the Price Index was 8.81%. The percentage of selfquotes was 5.18%. We confirmed a low proportion of original articles and an adequate percentage of satisfactory quotable articles. The low percentage of keywords that coincide with Medical Subject Headings is noteworthy. The bibliographical references found in the articles come mainly from the English-speaking area and from journals indexed in the Journal Citation Report. The obsolescence analysis of these references produced high results.

    Informative journal abstracts are crucial for the identification and initial appraisal of studies. We aimed to evaluate the informativeness of abstracts of diagnostic accuracy studies. PubMed was searched for reports of studies that had evaluated the diagnostic accuracy of a test against a clinical reference standard, published in 12 high-impact journals in 2012. Two reviewers independently evaluated the information contained in included abstracts using 21 items deemed important based on published guidance for adequate reporting and study quality assessment. We included 103 abstracts. Crucial information on study population, setting, patient sampling, and blinding as well as confidence intervals around accuracy estimates were reported in items per abstract was 10.1 of 21 (standard deviation 2.2). The mean number of reported items was significantly lower for multiple-gate (case-control type) studies, in reports in specialty journals, and for studies with smaller sample sizes and lower abstract word counts. No significant differences were found between studies evaluating different types of tests. Many abstracts of diagnostic accuracy study reports in high-impact journals are insufficiently informative. Developing guidelines for such abstracts could help the transparency and completeness of reporting. Copyright © 2015 Elsevier Inc. All rights reserved.

    This study evaluated physiotherapy students' perception of a reflective journal in developing reflective thinking and practice and identified the main concepts recorded by students in the journal. A mixed methods study with qualitative content analysis of student journals and quantitative analysis of questionnaire responses. 131 (74 female, 57 male) physiotherapy students undergoing their first clinical placement. On completion of their placement, students submitted a reflective journal electronically and completed a questionnaire of closed and open ended questions. Questionnaires were analysed using frequencies for the responses of the closed questions and thematic analysis of the open ended questions. Journals were de-indentified and underwent a content analysis using Leximancer software to obtain a concept map and frequencies of the main concepts identified in the journals, with specific examples. The majority (88%, 79/90) of respondents found the journal useful in assisting them to learn from their experiences, and to develop reflective thinking and practice. 54% (49/90) indicated they would continue to use the journals. The most frequently identified concepts were residents, time and exercises; representing more than 5000 of the total concepts identified in the journals. Analysis of the reflective journals indicated that students demonstrated improvements in the three stages of reflective practice: awareness of thoughts and feelings, critical analysis of situation, and development of new perspectives. Guided journal writing may be a useful tool in facilitating reflective thinking and practice during clinical placements of physiotherapy students. Copyright © 2012 Chartered Society of Physiotherapy.

    2011-07-01

    Full Text Available The past academic gender literature has focused on the underproduction of academic women in research outcomes and related reasons such as prejudice, more frequent career breaks and personality differences between genders.  This study examines the top six journals in the world and finds no difference between women and men productivity when the percentage of women participating in the academic work force is factored in. Women have a 30-35% participation rate in academic university positions and represented almost 30% of the authors in the top tiered journals. There are also no significantly statistical differences in Journal Impact Factor ratings between men and women. These findings are consistent across all the major disciplines, science, business and social science.  Other trends are noted such as the significantly higher number of authors in science journals and the different trends between US and non-US authors. Science authors’ quality (as measured by Journal Impact Factor (JIF of 31.9 is significantly higher than non-science authors (JIF 6.5; thus differences in quality are discipline specific not a gender issue. The implications are that academic women’s research contribution matches that of a man’s productivity.

    2002-09-01

    Full Text Available Abstract Background Physicians reading the medical literature attempt to determine whether research studies are valid. However, articles with negative results may not provide sufficient information to allow physicians to properly assess validity. Methods We analyzed all original research articles with negative results published in 1997 in the weekly journals BMJ, JAMA, Lancet, and New England Journal of Medicine as well as those published in the 1997 and 1998 issues of the bimonthly Annals of Internal Medicine (N = 234. Our primary objective was to quantify the proportion of studies with negative results that comment on power and present confidence intervals. Secondary outcomes were to quantify the proportion of these studies with a specified effect size and a defined primary outcome. Stratified analyses by study design were also performed. Results Only 30% of the articles with negative results comment on power. The reporting of power (range: 15%-52% and confidence intervals (range: 55–81% varied significantly among journals. Observational studies of etiology/risk factors addressed power less frequently (15%, 95% CI, 8–21% than did clinical trials (56%, 95% CI, 46–67%, p Conclusion Prominent medical journals often provide insufficient information to assess the validity of studies with negative results.

  1. Is it really theoretical? A review of sampling in grounded theory studies in nursing journals.

    Science.gov (United States)

    McCrae, Niall; Purssell, Edward

    2016-10-01

    Grounded theory is a distinct method of qualitative research, where core features are theoretical sampling and constant comparative analysis. However, inconsistent application of these activities has been observed in published studies. This review assessed the use of theoretical sampling in grounded theory studies in nursing journals. An adapted systematic review was conducted. Three leading nursing journals (2010-2014) were searched for studies stating grounded theory as the method. Sampling was assessed using a concise rating tool. A high proportion (86%) of the 134 articles described an iterative process of data collection and analysis. However, half of the studies did not demonstrate theoretical sampling, with many studies declaring or indicating a purposive sampling approach throughout. Specific reporting guidelines for grounded theory studies should be developed to ensure that study reports describe an iterative process of fieldwork and theoretical development. © 2016 John Wiley & Sons Ltd.

    Full Text Available This study aims to analyze the visibility of the journals that publish research on metric studies (MS by using the impact indicators of these journals, present at the databases Scopus and Web of Science (WOS. The selected journals represent the domain metric studies in the SciELO database and are present in the other databases, which were taken from their citation indicators. The study identifies the total number of each journal and the total number of publications related to metric studies in the 2009-2013 period, and the total number of citations received by each journal and his quote to MS articles in the time window 2009-2016, showing the average quotation by journal, areas and countries in the thematic and in their general publication. Soon after, it compares the citation measures given by the SJR of Scopus and the JCR Web of Science, pointing journals, areas and countries with the greatest impact on the theme and overall. It concludes that the majority of the journals have a higher number of citations in Scopus over the WOS, suggesting greater visibility in the first database to the articles about with metric studies. A similar situation occurs when considering any scientific journal and their citations received in relation to their overall impact. In relative terms, it observes that, in both databases, the Applied Social Sciences journals presents the highest percentage of articles on EMI in detriment to the other disciplines journals. Finally, it considers that Scopus indexing policies are responsible for their wider coverage and greater visibility of their journals, which are available in different languages.

  4. Evaluating the Effectiveness of an Antimicrobial Stewardship Program on Reducing the Incidence Rate of Healthcare-Associated Clostridium difficile Infection: A Non-Randomized, Stepped Wedge, Single-Site, Observational Study.

    Giulio DiDiodato

    Full Text Available The incidence rate of healthcare-associated Clostridium difficile infection (HA-CDI is estimated at 1 in 100 patients. Antibiotic exposure is the most consistently reported risk factor for HA-CDI. Strategies to reduce the risk of HA-CDI have focused on reducing antibiotic utilization. Prospective audit and feedback is a commonly used antimicrobial stewardship intervention (ASi. The impact of this ASi on risk of HA-CDI is equivocal. This study examines the effectiveness of a prospective audit and feedback ASi on reducing the risk of HA-CDI.Single-site, 339 bed community-hospital in Barrie, Ontario, Canada. Primary outcome is HA-CDI incidence rate. Daily prospective and audit ASi is the exposure variable. ASi implemented across 6 wards in a non-randomized, stepped wedge design. Criteria for ASi; any intravenous antibiotic use for ≥ 48 hrs, any oral fluoroquinolone or oral second generation cephalosporin use for ≥ 48 hrs, or any antimicrobial use for ≥ 5 days. HA-CDI cases and model covariates were aggregated by ward, year and month starting September 2008 and ending February 2016. Multi-level mixed effect negative binomial regression analysis was used to model the primary outcome, with intercept and slope coefficients for ward-level random effects estimated. Other covariates tested for inclusion in the final model were derived from previously published risk factors. Deviance residuals were used to assess the model's goodness-of-fit.The dataset included 486 observation periods, of which 350 were control periods and 136 were intervention periods. After accounting for all other model covariates, the estimated overall ASi incidence rate ratio (IRR was 0.48 (95% 0.30, 0.79. The ASi effect was independent of antimicrobial utilization. The ASi did not seem to reduce the risk of Clostridium difficile infection on the surgery wards (IRR 0.87, 95% CI 0.45, 1.69 compared to the medicine wards (IRR 0.42, 95% CI 0.28, 0.63.

    Full Text Available The dynamic behaviour of a double-helical gear system supported by journal bearings is theoretically and experimentally investigated in this study. A bending–torsional–axial coupling model for dynamic analysis of double-helical gear system is developed. Influence of the time-varying mesh stiffness and damping is considered. Oil film stiffness and damping of the supporting journal bearing are supposed to be time-varying, and the time-varying oil film stiffness and damping are predicted by a back propagation neural network, which is optimized by genetic algorithm. A double-helical gear–rotor–journal bearing system test rig is also established to carry out the experimental investigations, such as the dynamic transmission errors of gear pairs. The comparisons between theoretical and experimental results show that the time-varying oil film dynamic coefficients of journal bearings are an important internal excitation. The theoretical model with time-varying oil film stiffness and damping can predict the gear dynamics more accurate than the model with time-invariant oil film stiffness and damping, and the neural network optimized by genetic algorithm can obtain the time-varying oil film stiffness and damping efficiently and accurately for the dynamic analysis of double-helical gear system.

    Full Text Available This study sought to evaluate the effect of dialogue journal writing on writing performance as well as its different sub-components, namely content, organization, vocabulary, language use, and mechanics (Following Polio, 2013. Participants were 84 EFL intermediate learners who were selected based on their performance on Oxford Quick Placement Test (2004 and divided randomly into experimental and control groups. While the participants in the control group took part in descriptive writing pre and post-tests only, their counterparts in experimental group were asked to write 3 journals a week for about 6 months in the period between the pre- and post-tests. The instructor of the experimental group provided feedback to each journal entry mostly on its content and message to which the participants replied in a dialogic manner. Results of independent sample t-test located a significant difference between the experimental and control group regarding the overall writing performance, as well as the sub-components of content, organization, and vocabulary in the post-test. However, the obtained results did not reveal a significant effect of dialogue journal writing on language use and mechanics of writing performance. The results which promise implications for writing instructors, curriculum developers, and material designers are fully discussed.

  14. A Bibliometric Study to Manage a Journal Collection in an Astronomical Library: Some Results

    Science.gov (United States)

    Gomez, Monique

    The evaluation of the use of library collections is a fundamental tool for the development of a relevant and cost-effective collection. Bibliometrics offers several methods to measure the level of use of collections. In this paper, we present the first results of a bibliometric analysis of the references cited in the articles published by authors of the Instituto de Astrofísica de Canarias during the last decade. We have determined which kinds of publications and which journals are mainly used. We also have studied the ages of the cited journals and their cost-effectiveness. Additionally, to see if the advent of the WWW in the mid 1990s has influenced the reading or citing practices of the authors, we have compared two sets of data: articles published over the period 1991--3 that we define as the pre-WWW period and articles published over the period 1997--9 defined as the WWW period.

    2014-06-01

    Full Text Available Our article aims to explore how the emergence of independent journalism could reconfigure local news. Our field research, carried out from January to April 2013, focuses on two news-based websites in Toulouse: Carré d'infos and LibéToulouse. The results of our research show how newcomers to the world of independent journalism are struggling to maintain their business. A business which is even more precarious than that of their national counterparts, also highlighting the low number of readers and limited exposure they get within the local public space. However, our study has shown that these new players concentrate on field reporting, covering issues that mainstream media often does not and, in particular, cherishing their independence from local politics and economics.

  16. A comparative study on communication structures of Chinese journals in the social sciences

    CERN Document Server

    Zhou, Ping; Leydesdorff, Loet

    2010-01-01

    We argue that the communication structures in the Chinese social sciences have not yet been sufficiently reformed. Citation patterns among Chinese domestic journals in three subject areas -- political science and marxism, library and information science, and economics -- are compared with their counterparts internationally. Like their colleagues in the natural and life sciences, Chinese scholars in the social sciences provide fewer references to journal publications than their international counterparts; like their international colleagues, social scientists provide fewer references than natural sciences. The resulting citation networks, therefore, are sparse. Nevertheless, the citation structures clearly suggest that the Chinese social sciences are far less specialized in terms of disciplinary delineations than their international counterparts. Marxism studies are more established than political science in China. In terms of the impact of the Chinese political system on academic fields, disciplines closely r...

  17. Evaluation of Oil Film Pressure and Temperature of an Elliptical Journal Bearing - An Experimental Study

    2016-03-01

    Full Text Available The present study is aimed at experimental evaluation of both oil film pressure and temperature at the central plane of finite elliptical journal bearing configuration. These parameters have been obtained by running the machine at various speeds under different applied loads ranging from 500 N to 2000 N using three different grades of oil (HYDROL 32, 68 and 150. The data has been obtained through a test rig which is capable of measuring both pressure and temperature at the same location on the elliptical bearing profile. An elliptical journal bearing with journal diameter=100 mm, L/D ratio=1.0, Ellipticity Ratio=1.0 and radial clearance=0.1 mm has been designed and tested to access the pressure and temperature rise of the oil film at the central plane of the bearing. Two different lobes of positive pressure have been obtained for elliptical bearing which results in smaller area for cavitation zone and accounts for better thermal stability. Also, with the increase in load both pressure and temperature of an oil film increases for all the three grades of oil. Experimentally, it has been established that the HYDROL 68 is suitable grade of lubricating oil which gives the optimum rise of pressure and temperate under all operating conditions among the lubricating oils under study.

    To investigate the planning of subgroup analyses in protocols of randomised controlled trials and the agreement with corresponding full journal publications. Cohort of protocols of randomised controlled trial and subsequent full journal publications. Six research ethics committees in Switzerland, Germany, and Canada. 894 protocols of randomised controlled trial involving patients approved by participating research ethics committees between 2000 and 2003 and 515 subsequent full journal publications. Of 894 protocols of randomised controlled trials, 252 (28.2%) included one or more planned subgroup analyses. Of those, 17 (6.7%) provided a clear hypothesis for at least one subgroup analysis, 10 (4.0%) anticipated the direction of a subgroup effect, and 87 (34.5%) planned a statistical test for interaction. Industry sponsored trials more often planned subgroup analyses compared with investigator sponsored trials (195/551 (35.4%) v 57/343 (16.6%), P<0.001). Of 515 identified journal publications, 246 (47.8%) reported at least one subgroup analysis. In 81 (32.9%) of the 246 publications reporting subgroup analyses, authors stated that subgroup analyses were prespecified, but this was not supported by 28 (34.6%) corresponding protocols. In 86 publications, authors claimed a subgroup effect, but only 36 (41.9%) corresponding protocols reported a planned subgroup analysis. Subgroup analyses are insufficiently described in the protocols of randomised controlled trials submitted to research ethics committees, and investigators rarely specify the anticipated direction of subgroup effects. More than one third of statements in publications of randomised controlled trials about subgroup prespecification had no documentation in the corresponding protocols. Definitive judgments regarding credibility of claimed subgroup effects are not possible without access to protocols and analysis plans of randomised controlled trials. © The DISCO study group 2014.

    Full Text Available The present study investigates the extent of utilization of two meta tags – “keywords” and “descriptors” – in Web-based Open-Access Journals. A sample composed of 707 journals taken from DOAJ was used. These were analyzed on the account of utilization of the said meta tags. Findings demonstrated that these journals utilized “keywords” and “descriptors” meta-tags, 33.1% and 29.9% respectively. It was further demonstrated that among various subject classifications, “General Journals” had been the highest while “Mathematics and Statistics Journals” had the least utilization as “keywords” meta-tags. Moreover, “General Journals” and “Chemistry journals”, with 55.6% and 15.4% utilization respectively, had the highest and the lowest “descriptors” meta-tag usage rate. Based on our findings, and when compared against other similar research findings, there had been no significant growth experienced in utilization of these meta tags.

  20. REFLECTIVE PRACTICE THROUGH JOURNAL WRITING AND PEER OBSERVATION: A Case Study

    Directory of Open Access Journals (Sweden)

    2014-10-01

    Full Text Available Journal writing and Peer Observation in an educational context have become popular techniques, with several different types of applications. They have now been used quite widely in both language teaching and in teacher training. However, despite its reported advantages in both teaching and research, there are not many Peer Observation and Diary studies available based on the writing of experienced language teachers. The Teacher participants maintain Journal writing and Peer Observation as a means of reflective practice. They consider these practices as a mirror, which reflects the teacher’s own image as a practioner. The post-reflection discussion reveals that the teacher participants believe in reflective practice as an effective means of self-evaluation and of developing sensitivity to students’ learning. This paper examines Peer Observation and journal writing of two teachers working on the same language programme in terms of a variety of topic headings, and suggests that reflective practice can be a useful tool for both classroom research and teachers’ professional development.

    To evaluate the methodological adequacy of voice and laryngeal study designs published in speech-language pathology and otorhinolaryngology journals indexed for the ISI Web of Knowledge (ISI Web) and the MEDLINE database. A cross-sectional study conducted at the Universidade Federal de São Paulo (Federal University of São Paulo). Two Brazilian speech-language pathology and otorhinolaryngology journals (Pró-Fono and Revista Brasileira de Otorrinolaringologia) and two international speech-language pathology and otorhinolaryngology journals (Journal of Voice, Laryngoscope), all dated between 2000 and 2004, were hand-searched by specialists. Subsequently, voice and larynx publications were separated, and a speech-language pathologist and otorhinolaryngologist classified 374 articles from the four journals according to objective and study design. The predominant objective contained in the articles was that of primary diagnostic evaluation (27%), and the most frequent study design was case series (33.7%). A mere 7.8% of the studies were designed adequately with respect to the stated objectives. There was no statistical difference in the methodological quality of studies indexed for the ISI Web and the MEDLINE database. The studies published in both national journals, indexed for the MEDLINE database, and international journals, indexed for the ISI Web, demonstrate weak methodology, with research poorly designed to meet the proposed objectives. There is much scientific work to be done in order to decrease uncertainty in the field analysed.

    To determine the frequency and the main methodological characteristics of the epidemiological designs used in the research studies published in the journal Atencion Primaria between 1984 and 1990. A descriptive study. Included are all the articles presenting data produced by the authors themselves in the context of a research study and published in the sections of original articles, special contributions or clinical notes in the issues of the journal Atencion Primaria between 1984 and 1990. A data-gathering questionnaire was used, whose concordance was previously assessed blindly by two observers. There were 324 articles included. Of these, 93% were descriptive studies, out of which 27% were prevalence studies. Of these prevalence studies, 15.7% were conducted among the population as a whole. A questionnaire, which had been previously validated in 47.7% of cases, was used in 13.5% of the studies. Experimental research accounted for 21 studies (6.5%), of which 85% had an explicit control group. Only a small proportion are analytical studies. The majority of descriptive studies are carried out among the population attending for treatment.

    The current study evaluates the results of a previously reported method for creating a core medical electronic journal collection for a new medical school library, validates the core collection created specifically to meet the needs of the new school, and identifies strategies for making cost-effective e-journal selection decisions. Usage data were extracted for four e-journal packages (Blackwell-Synergy, Cell Press, Lippincott Williams & Wilkins, and ScienceDirect). Usage was correlated with weighted point values assigned to a core list of journal titles, and each package was evaluated for relevancy and cost-effectiveness to the Florida State University College of Medicine (FSU COM) population. The results indicated that the development of the core list was a valid method for creating a new twenty-first century, community-based medical school library. Thirty-seven journals are identified for addition to the FSU COM core list based on use by the COM, and areas of overlapping research interests between the university and the COM are identified based on use of specific journals by each population. The collection development approach that evolved at the FSU COM library was useful during the initial stages of identifying and evaluating journal selections and in assessing the relative value of a particular journal package for the FSU COM after the school was established.

    The effects of journal misalignment on the transient flow of a finite grooved journal bearing are presented in this study.A new 3D computational fluid dynamics (CFD) analysis method is applied.Also,the quasi-coupling calculation of transient fluid dynamics of oil film in journal bearing and rotor dynamics is considered in the analysis.Based on the structured mesh,a new approach for mesh movement is proposed to update the mesh volume when the journal moves during the fluid dynamics simulation of an oil film.Existing dynamic mesh models provided by FLUENT are not suitable for the transient oil flow in journal bearings.The movement of the journal is obtained by solving the moving equations of the rotor-bearing system with the calculated film pressure as the boundary condition of the load.The data exchange between fluid dynamics and rotor dynamics is realized by data files.Results obtained from the CFD model were consistent with previous experimental results on misalignedjournal bearings.Film pressure,oil film force,friction torque,misalignment moment and attitude angle were calculated and compared for misaligned and aligned journal bearings.The results indicate that bearing performances are greatly affected by misalignment which is caused by unbalanced excitation,and the CFD method based on the fluid-structure interaction (FSI) technique can effectively predict the transient flow field ofa misaligned journal bearing in a rotor-bearing system.

    2010-10-01

    Full Text Available BACKGROUND: transparency in reporting of conflict of interest is an increasingly important aspect of publication in medical journals. Publication of large industry-supported trials may generate many citations and journal income through reprint sales and thereby be a source of conflicts of interest for journals. We investigated industry-supported trials' influence on journal impact factors and revenue. METHODS AND FINDINGS: we sampled six major medical journals (Annals of Internal Medicine, Archives of Internal Medicine, BMJ, JAMA, The Lancet, and New England Journal of Medicine [NEJM]. For each journal, we identified randomised trials published in 1996-1997 and 2005-2006 using PubMed, and categorized the type of financial support. Using Web of Science, we investigated citations of industry-supported trials and the influence on journal impact factors over a ten-year period. We contacted journal editors and retrieved tax information on income from industry sources. The proportion of trials with sole industry support varied between journals, from 7% in BMJ to 32% in NEJM in 2005-2006. Industry-supported trials were more frequently cited than trials with other types of support, and omitting them from the impact factor calculation decreased journal impact factors. The decrease varied considerably between journals, with 1% for BMJ to 15% for NEJM in 2007. For the two journals disclosing data, income from the sales of reprints contributed to 3% and 41% of the total income for BMJ and The Lancet in 2005-2006. CONCLUSIONS: publication of industry-supported trials was associated with an increase in journal impact factors. Sales of reprints may provide a substantial income. We suggest that journals disclose financial information in the same way that they require them from their authors, so that readers can assess the potential effect of different types of papers on journals' revenue and impact.

    Full Text Available Background: Child abuse is a state of emotional, physical, economic and sexual maltreatment meted out to a person below the age of eighteen and is a globally prevalent phenomenon. A total of 33,098 cases of crimes against children were reported in India during 2011 as compared to 26,694 cases during 2010, suggesting a recent increase of 24 percent. Objectives: To explore the contents of the published articles/reports on child abuse in India from scientific journals and newspapers identifying areas and gaps for further research and program development. Material and Methods: Published articles in scientific journals during the years 2007-2012 with free access and online versions of English newspapers (2007-2012 in India were searched using the search engines such as ‘PubMed’ and ‘Google’. The key words used were ‘child abuse in (on, about India. First two researchers independently reviewed the content of articles/newspaper reports and decided the categories emerging from the articles and reports. Later on, the quantification of these categories was done by identifying the number of times it was reported in the reports. Results: The nature and extent of reporting child abuse in scientific journal is different from that of newspapers. In Journals, our search provided us with 9 articles, of which prevalence studies were predominant (4 followed by case reports (3 and Knowledge, Attitude, Practice studies (2. The studies were mostly conducted in the hospital setting. We obtained 38 reports from newspapers. Child abuse was found more among girls. Among type of abuse, sexual abuse was more common (84.2%. About 52.6% of the abusers were members known to the victim. The maximum cases were reported from West India especially in Goa, followed by South region. Most reports reported legal action on accused. Little was reported on what happened to a victim, indicators of abuse and settings of the abuse. The motives and consequences of the abuses were

  16. Implications of nonrandom seed abscission and global stilling for migration of wind-dispersed plant species.

    Thompson, Sally E; Katul, Gabriel G

    2013-06-01

    Migration of plant populations is a potential survival response to climate change that depends critically on seed dispersal. Biological and physical factors determine dispersal and migration of wind-dispersed species. Recent field and wind tunnel studies demonstrate biological adaptations that bias seed release toward conditions of higher wind velocity, promoting longer dispersal distances and faster migration. However, another suite of international studies also recently highlighted a global decrease in near-surface wind speeds, or 'global stilling'. This study assessed the implications of both factors on potential plant population migration rates, using a mechanistic modeling framework. Nonrandom abscission was investigated using models of three seed release mechanisms: (i) a simple drag model; (ii) a seed deflection model; and (iii) a 'wear and tear' model. The models generated a single functional relationship between the frequency of seed release and statistics of the near-surface wind environment, independent of the abscission mechanism. An Inertial-Particle, Coupled Eulerian-Lagrangian Closure model (IP-CELC) was used to investigate abscission effects on seed dispersal kernels and plant population migration rates under contemporary and potential future wind conditions (based on reported global stilling trends). The results confirm that nonrandom seed abscission increased dispersal distances, particularly for light seeds. The increases were mitigated by two physical feedbacks: (i) although nonrandom abscission increased the initial acceleration of seeds from rest, the sensitivity of the seed dispersal to this initial condition declined as the wind speed increased; and (ii) while nonrandom abscission increased the mean dispersal length, it reduced the kurtosis of seasonal dispersal kernels, and thus the chance of long-distance dispersal. Wind stilling greatly reduced the modeled migration rates under biased seed release conditions. Thus, species that require

    Numerous analyses of research published in scientific nursing journals have been examined over the past decades. However, a comprehensive analysis of trends in research has not been reported since 1980. The aim of this analysis was to review randomly selected research articles published in four scientific nursing journals for the years 1985, 1990, 1995, 2000, 2005, and 2010 to identify changes in selected aspects of research and to compare the findings with those from an earlier similar study. This descriptive study used percentages to present trends in published studies in four scientific nursing journals for twenty-five years. A total of 976 studies were identified; 50% were randomly selected for each year analyzed. The foci of the research problem, care orientation, conceptual bases, research designs, data analysis procedures, discussion of findings, and recommendations and implications were analyzed. Most studies from 1985 (66%) through 2010 (73%) focused on nursing practice issues; in 2010 they focused on primary health (46%) and chronicity (41%). A decrease in theory-testing research from 1985 (32%) to 2010 (21%), and in theory-based studies from 1985 (31%) to 2010 (22%) was noted. Qualitative studies increased from 1985 (3%) to 2010 (21%). Psychological variables and adult populations continue to be studied mainly over 25 years. For quantitative studies, there were increases in correlational designs from 1985 (35%) to 2010 (38%), experimental designs from 1985 (16%) to 2010 (18%), and methodological studies from 1985 (5%) to 2010 (24%). There were decreases in descriptive studies from 1985 (20%) to 2010 (5%), and comparative studies from 1985 (19%) to 2010 (10%). The use of multivariate statistics increased over time. In 1985, 61% of researchers did not link their findings to theory guiding the study; 52% did not in 2010. For qualitative research, approximately 50% fell in the "other category" over the 25 years; in 2010, grounded theory (15

    Full Text Available This case study is based on the experiences with the Electronic Journal of Information Technology in Construction (ITcon, founded in 1995. This journal is an example of a particular category of open access journals, which use neither author charges nor subscriptions to finance their operations, but rely largely on unpaid voluntary work in the spirit of the open source movement. The journal has, after some initial struggle, survived its first decade and is now established as one of half-a-dozen peer reviewed journals in its field. The journal publishes articles as they become ready, but creates virtual issues through alerting messages to “subscribers”. It has also started to publish special issues, since this helps to attract submissions, and also helps in sharing the work-load of review management. From the start the journal adopted a rather traditional layout of the articles. After the first few years the HTML version was dropped and papers are only published in PDF format. The journal has recently been benchmarked against the competing journals in its field. Its acceptance rate of 53% is slightly higher and its average turnaround time of seven months almost a year faster compared to those journals in the sample for which data could be obtained. The server log files for the past three years have also been studied. Our overall experience demonstrates that it is possible to publish this type of OA journal, with a yearly publishing volume equal to a quarterly journal and involving the processing of some fifty submissions a year, using a networked volunteer-based organization.

  20. The Nonrandom Brain: Efficiency, Economy, and Complex Dynamics

    Full Text Available Modern anatomical tracing and imaging techniques are beginning to reveal the structural anatomy of neural circuits at small and large scales in unprecedented detail. When examined with analytic tools from graph theory and network science, neural connectivity exhibits highly nonrandom features, including high clustering and short path length, as well as modules and highly central hub nodes. These characteristic topological features of neural connections shape nonrandom dynamic interactions that occur during spontaneous activity or in response to external stimulation. Disturbances of connectivity and thus of neural dynamics are thought to underlie a number of disease states of the brain, and some evidence suggests that degraded functional performance of brain networks may be the outcome of a process of randomization affecting their nodes and edges. This article provides a survey of the nonrandom structure of neural connectivity, primarily at the large-scale of regions and pathways in the mammalian cerebral cortex. In addition, we will discuss how nonrandom connections can give rise to differentiated and complex patterns of dynamics and information flow. Finally, we will explore the idea that at least some disorders of the nervous system are associated with increased randomness of neural connections.

  1. The Power-weakness Ratios (PWR as a Journal Indicator: Testing the “Tournaments” Metaphor in Citation Impact Studies

    Full Text Available Purpose: Ramanujacharyulu developed the Power-weakness Ratio (PWR for scoring tournaments. The PWR algorithm has been advocated (and used for measuring the impact of journals. We show how such a newly proposed indicator can empirically be tested. Design/methodology/approach: PWR values can be found by recursively multiplying the citation matrix by itself until convergence is reached in both the cited and citing dimensions; the quotient of these two values is defined as PWR. We study the effectiveness of PWR using journal ecosystems drawn from the Library and Information Science (LIS set of the Web of Science (83 journals as an example. Pajek is used to compute PWRs for the full set, and Excel for the computation in the case of the two smaller sub-graphs: (1 JASIST+ the seven journals that cite JASIST more than 100 times in 2012; and (2 MIS Quart+ the nine journals citing this journal to the same extent. Findings: A test using the set of 83 journals converged, but did not provide interpretable results. Further decomposition of this set into homogeneous sub-graphs shows that—like most other journal indicators—PWR can perhaps be used within homogeneous sets, but not across citation communities. We conclude that PWR does not work as a journal impact indicator; journal impact, for example, is not a tournament. Research limitations: Journals that are not represented on the “citing” dimension of the matrix—for example, because they no longer appear, but are still registered as “cited” (e.g. ARIST—distort the PWR ranking because of zeros or very low values in the denominator. Practical implications: The association of “cited” with “power” and “citing” with “weakness” can be considered as a metaphor. In our opinion, referencing is an actor category and can be Metaphor in Citation Impact Studies in terms of behavior, whereas “citedness” is a property of a document with an expected dynamics very different from that of

  2. Frugivores bias seed-adult tree associations through nonrandom seed dispersal: a phylogenetic approach.

    Frugivores are the main seed dispersers in many ecosystems, such that behaviorally driven, nonrandom patterns of seed dispersal are a common process; but patterns are poorly understood. Characterizing these patterns may be essential for understanding spatial organization of fruiting trees and drivers of seed-dispersal limitation in biodiverse forests. To address this, we studied resulting spatial associations between dispersed seeds and adult tree neighbors in a diverse rainforest in Madagascar, using a temporal and phylogenetic approach. Data show that by using fruiting trees as seed-dispersal foci, frugivores bias seed dispersal under conspecific adults and under heterospecific trees that share dispersers and fruiting time with the dispersed species. Frugivore-mediated seed dispersal also resulted in nonrandom phylogenetic associations of dispersed seeds with their nearest adult neighbors, in nine out of the 16 months of our study. However, these nonrandom phylogenetic associations fluctuated unpredictably over time, ranging from clustered to overdispersed. The spatial and phylogenetic template of seed dispersal did not translate to similar patterns of association in adult tree neighborhoods, suggesting the importance of post-dispersal processes in structuring plant communities. Results suggest that frugivore-mediated seed dispersal is important for structuring early stages of plant-plant associations, setting the template for post-dispersal processes that influence ultimate patterns of plant recruitment. Importantly, if biased patterns of dispersal are common in other systems, frugivores may promote tree coexistence in biodiverse forests by limiting the frequency and diversity of heterospecific interactions of seeds they disperse.

  3. How psychiatry journals support the unbiased translation of clinical research. A cross-sectional study of editorial policies.

    Full Text Available INTRODUCTION: Reporting guidelines (e.g. CONSORT have been developed as tools to improve quality and reduce bias in reporting research findings. Trial registration has been recommended for countering selective publication. The International Committee of Medical Journal Editors (ICMJE encourages the implementation of reporting guidelines and trial registration as uniform requirements (URM. For the last two decades, however, biased reporting and insufficient registration of clinical trials has been identified in several literature reviews and other investigations. No study has so far investigated the extent to which author instructions in psychiatry journals encourage following reporting guidelines and trial registration. METHOD: Psychiatry Journals were identified from the 2011 Journal Citation Report. Information given in the author instructions and during the submission procedure of all journals was assessed on whether major reporting guidelines, trial registration and the ICMJE's URM in general were mentioned and adherence recommended. RESULTS: We included 123 psychiatry journals (English and German language in our analysis. A minority recommend or require 1 following the URM (21%, 2 adherence to reporting guidelines such as CONSORT, PRISMA, STROBE (23%, 7%, 4%, or 3 registration of clinical trials (34%. The subsample of the top-10 psychiatry journals (ranked by impact factor provided much better but still improvable rates. For example, 70% of the top-10 psychiatry journals do not ask for the specific trial registration number. DISCUSSION: Under the assumption that better reported and better registered clinical research that does not lack substantial information will improve the understanding, credibility, and unbiased translation of clinical research findings, several stakeholders including readers (physicians, patients, authors, reviewers, and editors might benefit from improved author instructions in psychiatry journals. A first step of

    Biased negative studies not only reflect poor research effort but also have an impact on 'patient care' as they prevent further research with similar objectives, leading to potential research areas remaining unexplored. Hence, published 'negative studies' should be methodologically strong. All parameters that may help a reader to judge validity of results and conclusions should be reported in published negative studies. There is a paucity of data on reporting of statistical and methodological parameters in negative studies published in Indian Medical Journals. The present systematic review was designed with an aim to critically evaluate negative studies published in prominent Indian Medical Journals for reporting of statistical and methodological parameters. Systematic review. All negative studies published in 15 Science Citation Indexed (SCI) medical journals published from India were included in present study. Investigators involved in the study evaluated all negative studies for the reporting of various parameters. Primary endpoints were reporting of "power" and "confidence interval." Power was reported in 11.8% studies. Confidence interval was reported in 15.7% studies. Majority of parameters like sample size calculation (13.2%), type of sampling method (50.8%), name of statistical tests (49.1%), adjustment of multiple endpoints (1%), post hoc power calculation (2.1%) were reported poorly. Frequency of reporting was more in clinical trials as compared to other study designs and in journals having impact factor more than 1 as compared to journals having impact factor less than 1. Negative studies published in prominent Indian medical journals do not report statistical and methodological parameters adequately and this may create problems in the critical appraisal of findings reported in these journals by its readers.

    The study assessed 54 advertisements of 145 different drugs, published over one year (from December 2011 to November 2012) in an Indian medical journal, circulated widely mainly among general practitioners (GPs). The ethical guidelines of the World Health Organization (WHO) and Organisation of Pharmaceutical Producers of India (OPPI) for medicinal drug promotion were applied. The brand name was mentioned in all advertisements (100% compliance both with the WHO and OPPI criteria) and the names of the active ingredients were also mentioned in 128 (90.14%) advertisements. However, major adverse drug reactions were mentioned in only two advertisements (1.37%); precautions, contraindications and warnings in only two (1.37%); and major interactions in only one (0.68%). Only three advertisements (2.06%) were well substantiated with references. To ensure the ethical promotionof drugs among GPs, journals must introduce compulsory review and appraisal of promotional advertisements by a dedicated review board, including at least one member trained in pharmacology and one representative from the medical division of a pharmaceutical company.

  7. Study of design parameters for squeeze film air journal bearing – excitation frequency and amplitude

    2011-07-01

    Full Text Available The paper presents a design of squeeze film air journal bearing based on the design rules derived from CFX and FEA simulation study of an air film in between two flat plates, one of which was driven in a sinusoidal manner. The rules are that the oscillation frequency should be at least 15 kHz and that the oscillation amplitude be as large as possible to ensure a greater film thickness and to allow the bearing to reach its stable equilibrium quickly. The proposed journal bearing is made from AL2024-T3, of 20.02 mm outer diameter, 600 mm length and 2 mm thickness. Three 20-mm long fins are on the outer surface of the bearing tube and are spaced 120° apart; three longitudinal flats are milled equi-spaced between the fins and two piezoelectric actuators are mounted lengthwise on each flat. Such a design produces a modal shape on the bearing tube which resembles a triangle. When excited in this mode at the frequency of 16.37 kHz, and a voltage of 75 V AC with 75 V DC offset acting on the piezoelectric actuators, the air gap underneath of the bearing tube behaves as a squeeze air film with a response amplitude of 3.22 μm. The three design rules were validated by experiments.

    Lack of reproducibility of preclinical studies has been identified as an impediment for translation of basic mechanistic research into effective clinical therapies. Indeed, the National Institutes of Health has revised its grant application process to require more rigorous study design, including sample size calculations, blinding procedures, and randomization steps. We hypothesized that the reporting of such metrics of study design rigor has increased over time for animal-experimental research published in anesthesia journals. PubMed was searched for animal-experimental studies published in 2005, 2010, and 2015 in primarily English-language anesthesia journals. A total of 1466 publications were graded on the performance of sample size estimation, randomization, and blinding. Cochran-Armitage test was used to assess linear trends over time for the primary outcome of whether or not a metric was reported. Interrater agreement for each of the 3 metrics (power, randomization, and blinding) was assessed using the weighted κ coefficient in a 10% random sample of articles rerated by a second investigator blinded to the ratings of the first investigator. A total of 1466 manuscripts were analyzed. Reporting for all 3 metrics of experimental design rigor increased over time (2005 to 2010 to 2015): for power analysis, from 5% (27/516), to 12% (59/485), to 17% (77/465); for randomization, from 41% (213/516), to 50% (243/485), to 54% (253/465); and for blinding, from 26% (135/516), to 38% (186/485), to 47% (217/465). The weighted κ coefficients and 98.3% confidence interval indicate almost perfect agreement between the 2 raters beyond that which occurs by chance alone (power, 0.93 [0.85, 1.0], randomization, 0.91 [0.85, 0.98], and blinding, 0.90 [0.84, 0.96]). Our hypothesis that reported metrics of rigor in animal-experimental studies in anesthesia journals have increased during the past decade was confirmed.

    It is unclear how medical journals address authors' financial and non-financial conflict of interest (COI). To assess the policies of clinical journals for disclosure of financial and non-financial COI. Cross sectional study that included both review of public documents as well as a simulation of a manuscript submission for the National Library of Medicine's "core clinical journals". The study did not involve human subjects. Investigators who abstracted the data, reviewed "instructions for authors" on the journal website and, in order to reflect the actual implementation of the COI disclosure policy, simulated the submission of a manuscript. Two individuals working in duplicate and independently to abstract information using a standardized data abstraction form, resolved disagreements by discussion or with the help of a third person. All but one of 117 core clinical journals had a COI policy. All journals required disclosure of financial COI pertaining to the authors and a minority (35%) asked for financial COI disclosure pertaining to the family members or authors' institution (29%). Over half required the disclosure of at least one form of non-financial COI (57%), out of which only two (3%) specifically referred to intellectual COI. Small minorities of journals (17% and 24% respectively) described a potential impact of disclosed COI and of non-disclosure of COI on the editorial process. While financial COI disclosure was well defined by the majority of the journals, many did not have clear policies on disclosure of non-financial COI, disclosure of financial COI of family members and institutions of the authors, and effect of disclosed COI or non-disclosure of COI on editorial policies.

  11. Are shorter article titles more attractive for citations? Cross-sectional study of 22 scientific journals.

    2010-04-01

    To investigate the correlation between the length of the title of a scientific article and the number of citations it receives, in view of the common editorial call for shorter titles. Title and the number of citations to all articles published in 2005 in 22 arbitrarily chosen English-language journals (n=9031) were retrieved from citation database Scopus. The 2008 journal impact factors of these 22 journals were also retrieved from Thomson Reuters' Journal Citation Report (JCR). Assuming the article title length as the independent variable, and the number of citations to the article as the dependent variable, a linear regression model was applied. The slope of the regression line for some journals (n=6, when titles were measured in characters but 7 when titles were measured in words) was negative - none was significantly different from 0. The overall slope for all journals was 0.140 (when titles were measured in characters) and 0.778 (when titles were measured in words), which is significantly different from 0 (Pcitations - Spearman rho=0.266 - when titles were measured in characters, and rho=0.244 when titles were measured in words (Pjournals with impact factor >10 and for 2 out of 14 journals with impact factor citation rates. This association is more pronounced for journals with high impact factors. Editors who insist on brief and concise titles should perhaps update the guidelines for authors of their journals and have more flexibility regarding the length of the title.

  12. Good journalism or peace journalism?

    Directory of Open Access Journals (Sweden)

    David Loyn

    2007-10-01

    Full Text Available This paper argues against the prescriptive notions of Peace Journalism, and in particular its exclusive nature and attempt to define itself as a new orthodoxy. Most of the paper is a critique of the work of Jake Lynch and Annabel McGoldrick, in a book published in 2005, as well as their earlier Reporting the World series. They condemn all other ways of reporting as 'War Journalism, biased in favour of war.' I argue instead that the opposite of Peace Journalism is good journalism. Much of this Peace Journalism argument is derived from the work of Johan Galtung, who accuses 'war journalists' of reporting war in an enclosed space and time, with no context, concealing peace initiatives and making wars 'opaque/secret.' Galtung specifically calls on journalists as part of their mission to search out peace proposals which might begin as something small and beneath notice, but which might then be picked up and owned by politicians as their own. My response is clear and simple: creating peacemaking politicians is not the business of a reporter. I examine the traditional journalistic methods of using objectivity to get at a version of the truth. I concede that perfect truth is unattainable, (and paradoxically the tool of objectivity we use to get there is slippery too. I conclude that a more quotidian truth, or 'truthfulness' is though a manageable goal. I engage with philosophers who examine objectivity, concluding with the assistance of Thomas Nagel that it does still have a value. Nagel's account also has the merit of explaining how practices such as peace-reporting are bound to be less objective than alternatives, 'since they commit themselves to the adoption of particular perspectives, in effect giving up on the ideal of stripping away as much…as possible.' I examine the responses of the so-called 'journalism of attachment' framed as a desire of journalists faced by the horrors of Bosnia to cast off impartiality and emotional detachment and take

    2012-12-01

    This paper recommends how authors of statistical studies can communicate to general audiences fully, clearly, and comfortably. The studies may use statistical methods to explore issues in science, engineering, and society or they may address issues in statistics specifically. In either case, readers without explicit statistical training should have no problem understanding the issues, the methods, or the results at a non-technical level. The arguments for those results should be clear, logical, and persuasive. This paper also provides advice for editors of general journals on selecting high quality statistical articles without the need for exceptional work or expense. Finally, readers are also advised to watch out for some common errors or misuses of statistics that can be detected without a technical statistical background.

    2015-12-08

    Twitter is an increasingly popular means of research dissemination. I sought to examine the relation between scientific merit and mainstream popularity of general medical journals. I extracted impact factors and citations for 2014 for all general medical journals listed in the Thomson Reuters InCites Journal Citation Reports. I collected Twitter statistics (number of followers, number following, number of tweets) between July 25 and 27, 2015 from the Twitter profiles of journals that had Twitter accounts. I calculated the ratio of observed to expected Twitter followers according to citations via the Kardashian Index. I created the (Fifty Shades of) Grey Scale to calculate the analogous ratio according to impact factor. Only 28% (43/153) of journals had Twitter profiles. The scientific and social media impact of journals were correlated: in adjusted models, Twitter followers increased by 0.78% (95% confidence interval [CI] 0.38%-1.18%) for every 1% increase in impact factor and by 0.62% (95% CI 0.34%-0.90%) for every 1% increase in citations. Kardashian Index scores above the 99% CI were obsverved in 16% (7/43) of journals, including 6 of the 7 highest ranked journals by impact factor, whereas 58% (25/43) had scores below this interval. For the Grey Scale, 12% (5/43) of journals had scores above and 35% (15/43) had scores below the 99% CI. The size of a general medical journal's Twitter following is strongly linked to its impact factor and citations, suggesting that higher quality research received more mainstream attention. Many journals have not capitalized on this dissemination method, although others have used it to their advantage. © 2015 Canadian Medical Association or its licensors.

  16. Case studies identify savings of up to $40,000 for academic research laboratories with the use of video journals

    Pritsker, Moshe

    2015-04-01

    Recent studies indicate that 70% to 90% of results published in science journals are not reproducible, which presents troubling uncertainty about the future of scientific research. In contrast to the text format of traditional journals, novel video-based journals allow for systematic, step-by-step visualized demonstrations of research experiments. Video articles produce a more efficient transfer of knowledge between laboratories and therefore offer a viable solution to the issue of reproducibility. To quantify the savings of time and money generated by this alternative mode of scientific communication, we conducted a number of case studies among academic laboratories who use the peer-reviewed video journal JoVE. One study determined that using video as a guide to learn a new dissection technique saved a bioengineering lab at the University of Washington 40,000. A second case study found that a laboratory at Cornell University studying muscular dystrophy eliminated 6 months of experimentation by learning a new complex stem cell injection technique from the video journal. Results from a third study indicated that a laboratory at the University of Helsinki shortened the time to learn a surgical technique from 1 year to 2 weeks. Together, these studies indicate that video publication significantly enhances the reproducibility and productivity of scientific research.

    Alain R. Lamothe

    2012-05-01

    Full Text Available This paper reports the results of a quantitative analysis examining factors affecting electronic journal usage at the J.N. Desmarais Library of Laurentian University. This study covered an 11-year period, from 2000 to 2010. The number of full-text articles downloaded was compared to the size of the e-journal collection, the number of students, and the number of faculty members at the university, all of which exerted varying degrees of influence on the rate of use of e-journals. Pearson’s Product-Moment Correlation Coefficients were calculated to determine the strength of any existing linear relationship. Although the size of the e-journal collection did impact its level of use, there seems to be a “critical mass” which once reached will slow or stop any further increase in usage. Among the student population, the number of doctoral students demonstrated the strongest linear relationship to the use of the e-journal collection while the undergraduate population showed the least strong linear relationship. Faculty members were important users of the library’s e-journal collection but the linear relationship was not as strong as that observed for graduate students. In fact, faculty members demonstrated the least strong linear relationship of all segments of the Laurentian University community. It may be wise for the library to consult not only its faculty members but also its graduate students when seeking advice on collection building and management.

    Krause, Jan; Mele, S

    2007-01-01

    The recent debate on Open Access publishing in High-Energy Physics has exposed the problem of assessing the scienti c production of every country where scholars are active in this discipline. This assessment is complicated by the highly-collaborative cross-border tradition of High-Energy Physics research. We present the results of a quantitative study of the geographical distribution of authors of High-Energy Physics articles, which takes into account cross-border co-authorship by attributing articles to countries on a pro-rata basis. Aggregated data on the share of scienti c results published by each country are presented together with a breakdown for the most popular journals in the eld, and a separation for articles by small groups or large collaborations. Collaborative patterns across large geographic areas are also investigated. Finally, the High-Energy Physics production of each country is compared with some economic indicators.

  9. How journalism contributes to reproduce inequalities: an ethnographic study about news production

    Directory of Open Access Journals (Sweden)

    Marcia Veiga da Silva

    2011-12-01

    Full Text Available This article analyzes the data originated in a research carried out in order to cast some light on the participation of journalism in shaping values that create stereotypes and social inequalities. The research investigated how these values are formed and how they evolve. Through an ethnographic method, all the stages of the news production of a news broadcast were monitored along 11 weeks. The program is regularly broadcast by RBS TV, which belongs to Grupo RBS, the biggest communication conglomerate in Southern Brazil. Analyzing the daily routine of the journalists, with focus on the relationships they keep among themselves, and also on the productive routines, the study reached the conclusion that heterosexuality was a normative pattern that guided their personal and professional values in the decision-taking process, which resulted in presentations marked by hegemonic social values that reinforce hierarchies and inequalities from some social markers

    2011-01-01

    Colombian scientific journals are poorly represented in international digital libraries; however, through Google Scholar (GS) it is possible to determine their use by the community. Between the years of 2003 and 2007 a classification of 185 Colombian journals indexed in the Colombian National Bibliographical Index (IBNP) was performed using the information provided by GS, basing categorization on size indicators, indexation and citation. The indicators were analyzed by grouping the journals in two general areas: sciences and social sciences. In each area, the indicators provided by the digital libraries Scopus, Redalyc and Scielo were compared. Additionally, the indicators provided by IBNP journals categories (A1, A2, B and C) were also compared. The sciences and social sciences had a similar pattern in their indicators. The existence of positive correlations was established between some indicators and they predicted that the number of citations per journal in GS and the h index depends on its visibility in G...

    1977-01-01

    The consistent occurrence of nonrandom chromosome changes in human malignancies suggests that they are not trivial epiphenomena. Whereas we do not understand their significance at present, one possible role which they may fulfill is to provide the chromosomally aberrant cells with a proliferative advantage as the result of alteration of the number and/or location of genes related to nucleic acid biosynthesis. It would be expected that the proliferative advantage provided by various chromosome aberrations differs in patients with different genetic constitutions.

    Evidence-informed health policymaking logically depends on timely access to research evidence. To our knowledge, despite the substantial political and societal pressure to enhance the use of the best available research evidence in public health policy and program decision making, there is no study addressing availability of peer-reviewed research in Canadian health ministries. To assess availability of (1) a purposive sample of high-ranking scientific journals, (2) bibliographic databases, and (3) health library services in the fourteen Canadian health ministries. From May to October 2011, we conducted a cross-sectional survey among librarians employed by Canadian health ministries to collect information relative to availability of scientific journals, bibliographic databases, and health library services. Availability of scientific journals in each ministry was determined using a sample of 48 journals selected from the 2009 Journal Citation Reports (Sciences and Social Sciences Editions). Selection criteria were: relevance for health policy based on scope note information about subject categories and journal popularity based on impact factors. We found that the majority of Canadian health ministries did not have subscription access to key journals and relied heavily on interlibrary loans. Overall, based on a sample of high-ranking scientific journals, availability of journals through interlibrary loans, online and print-only subscriptions was estimated at 63%, 28% and 3%, respectively. Health Canada had a 2.3-fold higher number of journal subscriptions than that of the provincial ministries' average. Most of the organisations provided access to numerous discipline-specific and multidisciplinary databases. Many organisations provided access to the library resources described through library partnerships or consortia. No professionally led health library environment was found in four out of fourteen Canadian health ministries (i.e. Manitoba Health, Northwest

    Full Text Available Aims: To determine the quality of reporting in the proceedings of the All India Ophthalmological Conference (AIOC 2000, subsequent rate of publication in an indexed journal and differences between the proceedings and the journal version of these papers. Design: Observational study. Materials and Methods: All papers presented at the AIOC 2000 were retrieved from the proceedings and assessed for completeness of reporting. To determine the subsequent full publication, a Medline search was performed as of January 2007; consistency between the proceedings paper and the final publication was evaluated. Statistical analysis: Chi square and Fisher′s exact tests were used to compare publication rates based on geographical location, subspecialty and study design; Student′s t -test was used to compare differences based on the number of authors and sample size. Results: Two hundred papers were retrieved; many failed to include study dates, design or statistical methods employed. Thirty-three (16.5% papers were subsequently published in indexed journals by January 2007. The published version differed from the proceedings paper in 27 (81.8% instances, mostly relating to changes in author name, number or sequence. Conclusions: The overall quality of reporting of scientific papers in the proceedings of the AIOC 2000 was inadequate and many did not result in publication in an indexed journal. Differences between the published paper in journals and in proceedings were seen in several instances. Ophthalmologists should be cautious about using the information provided in conference proceedings in their ophthalmic practice.

  1. Study of journal bearing dynamics using 3-dimensional motion picture graphics

    Science.gov (United States)

    Brewe, D. E.; Sosoka, D. J.

    1985-01-01

    Computer generated motion pictures of three dimensional graphics are being used to analyze journal bearings under dynamically loaded conditions. The motion pictures simultaneously present the motion of the journal and the pressures predicted within the fluid film of the bearing as they evolve in time. The correct prediction of these fluid film pressures can be complicated by the development of cavitation within the fluid. The numerical model that is used predicts the formation of the cavitation bubble and its growth, downstream movement, and subsequent collapse. A complete physical picture is created in the motion picture as the journal traverses through the entire dynamic cycle.

    The influences of preload factor on the characteristics of three-lobe journal beating, such as dimen-sionless load capacity, attitude angle, stiffness coefficients and damping coefficients, were studied by using the numerical calculation. And the influences of eccentricity ratio and wide-to-diameter ratio on the characteristics of journal bearing were investigated as well. The results show that with the increasing of preload factor, eccen-tricity ratio and wide-to-diameter ratio, the dimensionless load capacity and damping coefficients increase; meanwhile, the absolute value of stiffness coefficients increases;and with the increasing of preload factor and eccentricity ratio and the decreasing of wide-to-diameter ratio, the attitude angle decreases. The study offers theoretical base for engineering application of three-lobe journal bearing.

    2016-03-29

    This article explores science journalism in the context of the media competition for readers' attention. It offers a qualitative stylistic perspective on how popular journalism colonizes science communication. It examines a sample of 400 headlines collected over the period of 15 months from the ranking of five 'most-read' articles on the website of the international magazineNew Scientist Dominant lexical properties of the sample are first identified through frequency and keyness survey and then analysed qualitatively from the perspective of the stylistic projection of newsworthiness. The analysis illustrates various degrees of stylistic 'hybridity' in online popularization of scientific research. Stylistic patterns that celebrate, domesticate or personalize science coverage (characteristic of popular journalism) are intertwined with devices that foreground tentativeness, precision and informativeness (characteristic of science communication). The article reflects on the implications of including various proportions of academic and popular styles in science journalism.

    Full Text Available We explore the use and usefulness of the hybrid open access publishing model in agricultural sciences using a combination of quantitative and qualitative methods. To ascertain the level of usage of the paid open access option in hybrid open access journals in agriculture, we studied the agriculture-related journals published by six commercial publishers. These publishers offer authors the option of paying a fee, often close to $3,000 per article, to make their article immediately freely available, usually with a Creative Commons license. We defined agriculture broadly but also assigned each journal to a subspecialty (e.g., animal science in order to see if there were differences based on these subdivisions. For each journal we gathered data for 2014-2015 and noted the total number of research articles and the number of those that were made freely available by authors paying the open access fee. To give context to our results we also surveyed local faculty in agricultural sciences, asking their reasons for considering the paid open access options and the sources of the funds to pay for it. Survey respondents were asked about their academic position and rank to see if there were differences to be noted. We also investigated the findability of the open access articles, noting if each individual publisher offered a way to easily locate all the freely available articles in a particular journal and if there are other avenues to easily locate these articles.

  13. Classroom Journal Club: Collaborative Study of Contemporary Primary Literature in the Biomechanics Classroom.

    Kuxhaus, Laurel; Corbiere, Nicole C

    2016-07-01

    Current engineering pedagogy primarily focuses on developing technical proficiency and problem solving skills; the peer-review process for sharing new research results is often overlooked. The use of a collaborative classroom journal club can engage students with the excitement of scientific discovery and the process of dissemination of research results, which are also important lifelong learning skills. In this work, a classroom journal club was implemented and a survey of student perceptions spanning three student cohorts was collected. In this collaborative learning activity, students regularly chose and discussed a recent biomechanics journal article, and were assessed based on specific, individual preparation tasks. Most student-chosen journal articles were relevant to topics discussed in the regular class lecture. Surveys assessed student perceptions of the activity. The survey responses show that, across all cohorts, students both enjoyed the classroom journal club and recognized it as an important learning experience. Many reported discussing their journal articles with others outside of the classroom, indicating good engagement. The results demonstrate that student engagement with primary literature can foster both technical knowledge and lifelong learning skills.

    Study design and statistical methods have become core components of medical research, and the methodology has become more multifaceted and complicated over time. The study of the comprehensive details and current trends of study design and statistical methods is required to support the future implementation of well-planned clinical studies providing information about evidence-based medicine. Our purpose was to illustrate study design and statistical methods employed in recent medical literature. This was an extension study of Sato et al. (N Engl J Med 2017; 376: 1086-1087), which reviewed 238 articles published in 2015 in the New England Journal of Medicine (NEJM) and briefly summarized the statistical methods employed in NEJM. Using the same database, we performed a new investigation of the detailed trends in study design and individual statistical methods that were not reported in the Sato study. Due to the CONSORT statement, prespecification and justification of sample size are obligatory in planning intervention studies. Although standard survival methods (eg Kaplan-Meier estimator and Cox regression model) were most frequently applied, the Gray test and Fine-Gray proportional hazard model for considering competing risks were sometimes used for a more valid statistical inference. With respect to handling missing data, model-based methods, which are valid for missing-at-random data, were more frequently used than single imputation methods. These methods are not recommended as a primary analysis, but they have been applied in many clinical trials. Group sequential design with interim analyses was one of the standard designs, and novel design, such as adaptive dose selection and sample size re-estimation, was sometimes employed in NEJM. Model-based approaches for handling missing data should replace single imputation methods for primary analysis in the light of the information found in some publications. Use of adaptive design with interim analyses is increasing

To do so, a systematic review of the literature was performed with the use of bibliometric study in the papers of the International Journal of Project Management (IJPM, included in SCOPUS, from its first volume to 2015, covering a period of more than 30 years. It was found that developing countries are increasingly concerned in developing research into the field of project management, especially in mega infrastructure projects and public-private partnerships. The risk is a central topic in all periods of analysis, however, the strategic topics such as success in project and portfolio management are among the fastest growing. Issues related to the soft side of project management as skills, culture, and knowledge management have emerged in recent periods. According to the industry, construction projects and projects in information technology are the most studied along the period analysed.

    Electronic journals are so embedded into practice in academic libraries that it is easy to forget that this is not the case everywhere. In NHS libraries, for example, the staff face a particular set of issues. This article is based on Rebecca England's dissertation on this topic, completed as part of the MSc Econ course in Information and Library studies at Aberystwyth University. Rebecca is E-resources Librarian at the Maidstone and Tunbridge Wells NHS Trust. She investigated the momentum towards electronic journals in NHS libraries in the Kent, Surrey and Sussex region and the potential for a regional purchasing consortium.

    Articles from open access and local journals are important resources for research in Korea and the usage trends of these articles are important indicators for the assessment of the current research practice. We analyzed an institutional collection of published papers from 1998 to 2014 authored by researchers from Seoul National University, and their references from papers published between 1998 and 2011. The published papers were collected from Web of Science or Scopus and were analyzed according to the proportion of articles from open access journals. Their cited references from published papers in Web of Science were analyzed according to the proportion of local (South Korean) or open access journals. The proportion of open access papers was relatively stable until 2006 (2.5 ~ 5.2% in Web of Science and 2.7 ~ 4.2% in Scopus), but then increased to 15.9% (Web of Science) or 18.5% (Scopus) in 2014. We analyzed 2,750,485 cited references from 52,295 published papers. We found that the overall proportion of cited articles from local journals was 1.8% and that for open access journals was 3.0%. Citations of open access articles have increased since 2006 to 4.1% in 2011, although the increase in open access article citations was less than for open access publications. The proportion of citations from local journals was even lower. We think that the publishing / citing mismatch is a term to describe this difference, which is an issue at Seoul National University, where the number of published papers at open access or local journals is increasing but the number of citations is not. The cause of this discrepancy is multi-factorial but the governmental / institutional policies, social / cultural issues and authors' citing behaviors will explain the mismatch. However, additional measures are also necessary, such as the development of an institutional citation database and improved search capabilities with respect to local and open access documents.

    Despite widespread adoption of simulation-based training in medical education, there remains scepticism about its cost-effectiveness and long-term impact on patient outcomes. Medical simulation is well established in anaesthesia where it is considered an important educational tool. This review of key clinical anaesthesia literature is used as a case study of clinician uptake within a specialty and to investigate evidence for translational impact using both qualitative and quantitative data. We examined high-impact journal publications from 2001 to 2010 and extracted data covering authors, institutions, simulation modality, purposes of simulation, and various aspects of study design/methodology used. A total of 320 papers containing primary data were included. We found broad acceptance and uptake in anaesthesia with an increase in publications over the time period, mainly attributable to a steady increase in manikin studies. Studies using manikin technology (130/320; 41%) are distinguished as skills/performance studies (76; 58%) and studies focused on the use, testing, and validation of equipment (52; 40%). A total of 110 papers (34%) assessed the performance of technical and non-technical skills (68% and 32%, respectively). Growth in the use of structured checklists/validated tools to assess performance is mainly observed in the non-technical domain. Only 10% of these papers include follow-up data from the clinical environment. There is a lack of research examining performance transfer, sustainability, and direct patient outcomes and experiences. These publication patterns are instructive for those involved in medical educational and for other clinical specialties developing simulation.

    2017-01-01

    Objective The research assessed nursing faculty awareness and knowledge of the journal impact factor (JIF) and its impact on their publication choices. Methods A qualitative cross-sectional questionnaire was developed using Fluid Survey and distributed electronically to nursing faculty and instructors at three post-secondary institutions in Saskatchewan. Data were collected on place and status of employment, knowledge and awareness of JIFs, and criteria used to choose journals for publication. Results A total of forty-four nursing faculty and instructors completed the questionnaire. The authors found that faculty lack awareness or complete understanding of JIFs and that JIFs are not the most important or only criterion used when they choose a journal for publication. Conclusions There are various reasons for choosing a journal for publication. It is important for librarians to understand faculty views of JIFs and their criteria for choosing journals for publication, so that librarians are better equipped to guide researchers in considering their academic goals, needs, and personal values.

    Scientometrics is an emerging academic field for the exploration of the structure of science through journal citation relations.However,this article aims to study those subject-relevant journals’contents rather than studying their citations contained therein with the purpose of discovering a given disciplinary structure of science such as mechanics in our case.Based on the title wordings of 68,075 articles published in 66 mechanics journals,and using such research tools as the word frequency analysis,multidimensional scaling analysis and factor analysis,this article analyzes similarity and distinctions of those journals’contents in the subject field of mechanics.We first convert complex internal relations of these mechanics journals into a small number amount of independent indicators.The group of selected mechanics journals is then classified by a cluster analysis.This article demonstrates that the relations of the research contents of mechanics can be shown in an intuitively recognizable map,and we can have them analyzed from a perspective by taking into account about how those major branches of mechanics,such as solid mechanics,fluid mechanics,rational mechanics(including mathematical methods in mechanics),sound and vibration mechanics,computational mechanics,are related to the main thematic tenet of our study.It is hoped that such an approach,buttressed with this new perspective and approach,will enrich our means to explore the disciplinary structure of science and technology in general and mechanics in specific.

    In the past decade, scientific research has developed rapidly in China, but the growth seems to vary widely between different disciplines. In this study, we aimed to compare the quantity and quality of publications in urology and nephrology journals from USA, China and Japan. Journals listed in the "Urology and Nephrology" category of Science Citation Index Expanded subject categories were included. Scientific papers in these journals written by researchers from USA, Japan and China were retrieved from the "PubMed" and "Web of Knowledge" online databases. The annual number of total scientific articles increased significantly from 2001 to 2010 in China, and has ranked second in the world since 2006. In the field of urology and nephrology, the annual number increased significantly from 2001 to 2010 in USA and China; but not in Japan. The share of articles increased significantly over time in China, decreased significantly in Japan, and remained unchanged in USA. In 2010, USA contributed 32.17% of the total world output in urology and nephrology field and ranked 1(st); Japan contributed 5.19% and ranked 5(th); China contributed 3.83% and ranked 9(th). Publications from USA had the highest accumulated IFs and the highest total citations of articles (USA>Japan>China, pJapan(6704)>China(2233), pJapan>China, pscientific publication in urology and nephrology journals in the past decade, it still lags far behind USA and Japan in the field of urology and nephrology in terms of quantity and quality.

    Full Text Available This paper explores students’ motivation to study journalism, the expectations that students had regarding the study, and the fulfillment of those expectations. The survey was conducted on a convenience sample of journalism students at the Faculty of Political Sciences in Zagreb (academic year 2010-2011, which included: 1st and 3rd year students of undergraduate study and 2nd year students of graduate study. Since the selected questions were open-ended, the obtained responses were widely dispersed, and were later classified into defined categories after the survey. The results show that the most common reason among students to study journalism is a wish to enroll in that specific study and the desire to work in the media. The expectations that students have mainly refer to good and adequate training. In their senior year of study (3rd year of undergraduate and 2nd year of graduate study, there are many disappointed students as a result of unfulfilled expectations (mainly because of the lack of practice and practical subjects.

  15. Discovering non-random segregation of sister chromatids: The naïve treatment of a premature discovery

    Directory of Open Access Journals (Sweden)

    Karl G. Lark

    2013-02-01

    Full Text Available The discovery of non-random chromosome segregation is discussed from the perspective of what was known in1965 and1966. The distinction between daughter, parent or grandparent strands of DNA was developed in a bacterial system and led to the discovery that multiple copies of DNA elements of bacteria are not distributed randomly with respect to the age of the template strand. Experiments with higher eukaryotic cells demonstrated that during mitosis Mendel’s laws were violated; and the initial serendipitous choice of eukaryotic cell system led to the striking example of non-random segregation of parent and grand-parent DNA template strands in primary cultures of cells derived from mouse embryos. Attempts to extrapolate these findings to established TC lines demonstrated that the property could be lost. Experiments using plant root tips demonstrated that the phenomenon exists in plants and that it was, at some level, under genetic control. Despite publication in major journals and symposia (Lark et al. (1966a; Lark (1967a; 1967b; 1969, 1969a; 1969b the potential implications of these findings were ignored for several decades. Here we explore possible reasons for the pre-maturity (Stent, 1972 of this discovery.

  16. Non-random mate choice in humans: insights from a genome scan.

    Laurent, R; Toupance, B; Chaix, R

    2012-02-01

    Little is known about the genetic factors influencing mate choice in humans. Still, there is evidence for non-random mate choice with respect to physical traits. In addition, some studies suggest that the Major Histocompatibility Complex may affect pair formation. Nowadays, the availability of high density genomic data sets gives the opportunity to scan the genome for signatures of non-random mate choice without prior assumptions on which genes may be involved, while taking into account socio-demographic factors. Here, we performed a genome scan to detect extreme patterns of similarity or dissimilarity among spouses throughout the genome in three populations of African, European American, and Mexican origins from the HapMap 3 database. Our analyses identified genes and biological functions that may affect pair formation in humans, including genes involved in skin appearance, morphogenesis, immunity and behaviour. We found little overlap between the three populations, suggesting that the biological functions potentially influencing mate choice are population specific, in other words are culturally driven. Moreover, whenever the same functional category of genes showed a significant signal in two populations, different genes were actually involved, which suggests the possibility of evolutionary convergences.

  17. Three journal similarity metrics and their application to biomedical journals.

    In the present paper, we have created several novel journal similarity metrics. The MeSH odds ratio measures the topical similarity of any pair of journals, based on the major MeSH headings assigned to articles in MEDLINE. The second metric employed the 2009 Author-ity author name disambiguation dataset as a gold standard for estimating the author odds ratio. This gives a straightforward, intuitive answer to the question: Given two articles in PubMed that share the same author name (lastname, first initial), how does knowing only the identity of the journals (in which the articles were published) predict the relative likelihood that they are written by the same person vs. different persons? The article pair odds ratio detects the tendency of authors to publish repeatedly in the same journal, as well as in specific pairs of journals. The metrics can be applied not only to estimate the similarity of a pair of journals, but to provide novel profiles of individual journals as well. For example, for each journal, one can define the MeSH cloud as the number of other journals that are topically more similar to it than expected by chance, and the author cloud as the number of other journals that share more authors than expected by chance. These metrics for journal pairs and individual journals have been provided in the form of public datasets that can be readily studied and utilized by others.

    2014-01-01

    Analyzing a large data set of publications drawn from the most competitive journals in the natural and social sciences we show that research careers exhibit the broad distributions of individual achievement characteristic of systems in which cumulative advantage plays a key role. While most researchers are personally aware of the competition implicit in the publication process, little is known about the levels of inequality at the level of individual researchers. We analyzed both productivity and impact measures for a large set of researchers publishing in high-impact journals. For each researcher cohort we calculated Gini inequality coefficients, with average Gini values around 0.48 for total publications and 0.73 for total citations. For perspective, these observed values are well in excess of the inequality levels observed for personal income in developing countries. Investigating possible sources of this inequality, we identify two potential mechanisms that act at the level of the individual that may play...

    Full Text Available We present here an analysis of papers on teacher education published in journals of the science teaching area in Brazil, covering the period of 1979 to 2007. The following journals taken part of this analysis: Revista Brasileira de Ensino de Física, Caderno Brasileiro de Ensino de Física, Ciência & Educação, Investigações em Ensino de Ciências, Ensaio: pesquisa em educação em ciências, Revista Brasileira de Pesquisa em Educação em Ciências. In order to develop this research we took the textual analysis as a general methodology for collecting and analyzing data. For the systematization of information were highlighted words and phrases of the title, keywords and the summary presented in the papers. Systematized information shows that this theme has always been one of the focuses of research journals. The analysis undertaken allowed the delimitation of a corpus which is the starting point for a more extensive and detailed research on the field. As a first result we found 112 words, summarized in 6 categories (action, attributes, constitution, identity, profession and knowledge which allowed a broad characterization of the science teacher’s education field in Brazil.

  4. Inbreeding avoidance through non-random mating in sticklebacks.

    Frommen, Joachim G; Bakker, Theo C M

    2006-06-22

    Negative effects of inbreeding are well documented in a wide range of animal taxa. Hatching success and survival of inbred offspring is reduced in many species and inbred progeny are often less attractive to potential mates. Thus, individuals should avoid mating with close kin. However, experimental evidence for inbreeding avoidance through non-random mating in vertebrates is scarce. Here, we show that gravid female three-spined sticklebacks (Gasterosteus aculeatus) when given the choice between a courting familiar brother and a courting unfamiliar non-sib prefer to mate with the non-sib and thus avoid the disadvantages of incest. We controlled for differences in males' body size and red intensity of nuptial coloration. Thus, females adjust their courting behaviour to the risk of inbreeding.

  5. Evidence for Non-Random Hydrophobicity Structures in Protein Chains

    Irbäck, A; Potthast, F; Irb\\"ack, Anders; Peterson, Carsten; Potthast, Frank

    1996-01-01

    The question of whether proteins originate from random sequences of amino acids is addressed. A statistical analysis is performed in terms of blocked and random walk values formed by binary hydrophobic assignments of the amino acids along the protein chains. Theoretical expectations of these variables from random distributions of hydrophobicities are compared with those obtained from functional proteins. The results, which are based upon proteins in the SWISS-PROT data base, convincingly show that the amino acid sequences in proteins differ from what is expected from random sequences in a statistical significant way. By performing Fourier transforms on the random walks one obtains additional evidence for non-randomness of the distributions. We have also analyzed results from a synthetic model containing only two amino-acid types, hydrophobic and hydrophilic. With reasonable criteria on good folding properties in terms of thermodynamical and kinetic behavior, sequences that fold well are isolated. Performing t...

    2011-07-01

    Ceramic is the oldest synthetic material created by the mankind and has been present in human societies from around ten thousand years ago. During the last few decades, within the research field of Archaeometry, the study of archaeological and historical ceramic materials has experienced a significant increase in the application of chemical-physical techniques to obtain information on technology and production of these materials in the past. This paper presents the results obtained in a biblio metric study undertaken on 589 articles published on this subject in JCR journals and conference proceedings during the last decade (2000-2010). The main purpose of this research was to address the recent evolution and trends of this kind of investigations. The parameters analyzed were: date of publication, type of journal, topic, cultural-chronological classification of materials studied, origin country of authors, and analytical techniques used. Resulting data indicated a continual, stable, and growing publication rate on the subject in journals and conference proceedings of the three JCR indexes, namely SCI, AHCI, and SSCI, which evidences a high level of interdisciplinary. Authors from Europe and the United States carried out the majority of contributions. (Author) 30 refs.

  9. A Study of the Subject Categorization of the MIS-related Journals in the ISI Databases Using Topical Features in the Text Content and Machine Learning Methods

    Sung-Chien Lin

    2015-07-01

    Full Text Available In this study we analyzed and discussed that the MIS-related journals under the ISI subject category of IS&LS are simultaneously given with subject category Management, using methods of topic modeling, journal clustering and subject category prediction. In the experiment of journal clustering, all journals under subject category Management and other journals also having similar topical features can be gathered into a cluster, and “management” is their common and the most distinct topic. Because the journals belonged to this cluster are almost same to those in the MIS clusters generated by the previous studies, we considered it as the MIS cluster in this study. In the second experiment, we used the classification and regression tree (CART technique to predict assignment of subject category with that the journals in the original subject category Management and in the MIS cluster produced in this study as positive examples, respectively. The trees generated by the two tests both used the occurring probabilities of the topic “management” as the main classification rule. However, in the latter test, we did not only obtain a simpler classification tree but also had a result with less predicting errors. This means that if all journals in the MIS cluster could be given with subject category Management, the retrieval results can be more effective and complete.

    2003-08-01

    Despite its many imperfections, the peer review process is a firmly established quality control system for scientific literature. It gives readers some assurance that the work and views that are reported meet standards that are acceptable to a journal. Maureen Revington's editorial in a recent issue of the Australian Veterinary Journal (Revington2002) gives a good concise warts and all overview of the process and is well worth reading. I have some concerns about several articles in the December 2002 issue of the New Zealand Veterinary Journal (Volume 50, Number 6), devoted to the health and welfare of farmed deer, that relate to extensive citing of non-peer reviewed papers. I can understand the need for information to flow from researchers to the wider community but that need is already satisfied by publications such as the proceedings of the Deer Branch of the New Zealand Veterinary Association and Proceedings of the New Zealand Society of Animal Production. Non-peer reviewed papers have been cited in the Journal in the past but never to the extent displayed in this particular issue. It degrades the peer-review process and creates an added burden for reviewers who are forced to grapple with the uncertainties of the science in non-peer reviewed citations. One of my fears is that this process allows science from non peer reviewed articles to be legitimised by its inclusion in a peer reviewed journal and perhaps go on to be accepted as dogma. This is a real danger given the difficulties associated with tracing back to original citations and the increasing volume of scientific literature. It also affords opportunities for agencies to pick up questionable and doubtful science and tout it as support for their products or particular points of view. If deer researchers choose to publish most of their work in proceedings then so be it. However this approach, which seems to becoming increasingly prevalent in the deer sector, is questionable from an established science point

    Cognitive behavioural therapy (CBT) has been useful in the treatment of chronic pain conditions for many years. Given the increasing number of persons with chronic pain and associated psychosocial problems, the development and implementation of effective interventions based on CBT is warranted. The aim of this study is to evaluate the effects of a multidisciplinary pain management programme on health-related quality of life (HRQL), as measured by the Short Form Health Survey (SF-36), pain perception as measured by the Brief Pain Inventory (BPI), and readiness-to-change as measured by the Pain Stages of Change Questionnaire (PSOCQ). A pretest-post-test quasi-experimental design, with waiting list controls and baseline and post-test measures, was used. The study was conducted in the rehabilitation unit of a university hospital. Of 117 people suffering from chronic pain, 113 completed the 8-week multidisciplinary pain management programme. The patients were consecutive referrals. Inclusion criteria were: adults (18-67 years), pain lasting over 6 months, motivation and no ongoing litigation. Exclusion criteria were affected by major mental disorders or major medical conditions requiring treatment. The intervention was based on a cognitive behavioural approach. Therapeutic dialogues and training, combined with physical activity, were provided to a fixed plan, including homework. The programme has several features that directly address psychosocial aspects of chronic pain. Statistical and clinical significance are considered. The findings suggest that this programme has the potential to improve HRQL, reduce pain intensity and interference, and contribute to improvement in readiness-to-change. Statistically significant results are supplemented by results showing their clinical significance. Improvements in HRQL, pain-related disability, and readiness-to-change suggest that the vicious cycle of chronic pain may be alleviated by our programme. As we see it, effective

    Full Text Available We explored the effectiveness of loxoprofen sodium (loxoprofen, which is the most common non-steroidal anti-inflammatory drug (NSAID in Japan, for patients with benign prostatic hyperplasia (BPH complaining of nocturia. A total of 93 BPH patients aged 49-84 years were enrolled in the study. These patients had received standard drug therapy with alpha1-blocker for BPH, followed by anticholinergic drugs, hypnotics, tricyclic antidepressants, and/or antiduretic hormone, but they still complained about 2 or more episodes of nocturia. They each took a single 60-mg tablet of loxoprofen prior to sleeping at night for 14 days in addition to their BPH treatments. The effects were assessed by questionnaire before and after treatment as excellent (nocturia disappeared or decreased by 2 or more voids/night, improved (nocturia decreased by 1 void/night, unchanged, or worsened (nocturia increased. Nocturia improved or disappeared in 74.2% of patients: excellent, improved, unchanged, and worsened results were obtained in 37.6%, 36.6%, 21.5%, and 4.3% of patients, respectively. The effects were better in patients whose baseline nocturia was > 2 times than in those with a lesser frequency at enrollment (P = 0.04. Loxoprofen can be an effective and useful treatment option for patients with BPH complaining of refractory nocturia.

    Full Text Available Abstract Background In recent years an increasing number of patients have been referred to the medical sector with stress symptoms. Moreover, these conditions imply increased sickness absence. This indicates a need for treatment programmes in general medical practice. The aim of this study was to test the effect of a multidisciplinary stress treatment programme on the return to work (RTW rate in persons with work-related stress and establish predictive factors for this outcome. Methods During a two-year period 63 out of 73 referrals to the Stress Clinic (a section of a Clinic of Occupational Medicine completed a stress treatment programme consisted of the following: 1 Identification of relevant stressors. 2. Changing the coping strategies of the participants. 3. Evaluating/changes in participant workload and tasks. 4. Relaxation techniques. 5. Physical exercise. 6. Psychiatric evaluation when indicated by depression test score. On average each patient attended six one-hour sessions over the course of four months. A group of 34 employees referred to the Clinic of Occupational Medicine by their general practitioners served as a control group. Each participant had a one-hour consultation at baseline and after four months. A specialist in occupational medicine carried out all sessions. Return To Work (RTW, defined as having a job and not being on sick leave at the census, was used as outcome measure four months after baseline, and after one and two years. Results The level of sick leave in the stress treatment group dropped from 52% to 16% during the first four months of follow-up and remained stable. In the control group, the reduction in sick leave was significantly smaller, ranging from 48% at baseline to 27% after four months and 24% after one year. No statistically significant difference between the two groups was observed after one and two years. Age below 50 years and being a manager increased the odds ratio for RTW after one and two years

    1988-03-01

    The statistical quality of 103 original articles published in The Journal of Bone and Joint Surgery (British Volume) in 1984 was assessed. Some papers were found to be deficient: thus, it was not always clear how series were selected and sometimes neither the data nor the results were clearly presented. Sample sizes were frequently inadequate for the conclusions reached and statistical techniques should have been used more frequently. A majority of papers were descriptions of case series for which no comparative data were made available. It is suggested that collaborative research would best advance knowledge about the relative benefits of various managements, and that statistical advice could make a substantial contribution.

    Full Text Available This study aims to assess the methodological rigor of case studies in management accounting published in Brazilian journals. The study is descriptive. The data were collected using documentary research and content analysis, and 180 papers published from 2008 to 2012 in accounting journals rated as A2, B1, and B2 that were classified as case studies were selected. Based on the literature, we established a set of 15 criteria that we expected to be identified (either explicitly or implicitly in the case studies to classify those case studies as appropriate from the standpoint of methodological rigor. These criteria were partially met by the papers analyzed. The aspects less aligned with those proposed in the literature were the following: little emphasis on justifying the need to understand phenomena in context; lack of explanation of the reason for choosing the case study strategy; the predominant use of questions that do not enable deeper analysis; many studies based on only one source of evidence; little use of data and information triangulation; little emphasis on the data collection method; a high number of cases in which confusion between case study as a research strategy and as data collection method were detected; a low number of papers reporting the method of data analysis; few reports on a study's contributions; and a minority highlighting the issues requiring further research. In conclusion, the method used to apply case studies to management accounting must be improved because few studies showed rigorous application of the procedures that this strategy requires.

    A time-honored strategy for keeping up to date in medicine and improving critical appraisal skills is the Journal Club (JC). There are several reports of its use in medicine and allied health sciences but almost no reports of JC focused on medical education. The purpose of the study is to describe and evaluate an eight years' experience with a medical education Journal Club (MEJC). We started a monthly medical education JC in 2006 at UNAM Faculty of Medicine in Mexico City. Its goal is to provide faculty with continuing professional development in medical education. A discussion guide and a published paper were sent 2 weeks before sessions. We reviewed the themes and publication types of the papers used in the sessions, and in June-July 2014 administered a retrospective post-then-pre evaluation questionnaire to current participants that had been regular attendees to the JC for more than 2 years. The retrospective post-then-pre comparisons were analyzed with Wilcoxon signed-rank test. Effect sizes were calculated for the pre-post comparisons with Cohen's r. There have been 94 MEJC sessions until July 2014. Average attendance is 20 persons, a mix of clinicians, educators, psychologists and a sociologist. The articles were published in 32 different journals, and covered several medical education themes (curriculum, faculty development, educational research methodology, learning methods, assessment, residency education). 22 Attendees answered the evaluation instrument. The MEJC had a positive evaluation from good to excellent, and there was an improvement in self-reported competencies in medical education literature critical appraisal and behaviors related to the use of evidence in educational practice, with a median effect size higher than 0.5. The evaluation instrument had a Cronbach's alpha of 0.96. A periodic Medical Education Journal Club can improve critical appraisal of the literature, and be maintained long-term using evidence-based strategies. This activity

    Context Over the past three decades, industry sponsored research expanded in the United States. Financial incentives can lead to potential conflicts of interest (COI) resulting in underreporting of negative study results. Objective We hypothesized that over the three decades, there would be an increase in: a) reporting of conflict of interest and source of funding; b) percentage of randomized control trials c) number of patients per study and d) industry funding. Data sources and Study Selection Original articles published in three calendar years (1988, 1998, and 2008) in The Lancet, New England Journal of Medicine and Journal of American Medical Association were collected. Data Extraction Studies were reviewed and investigational design categorized as prospective and retrospective clinical trials. Prospective trials were categorized into randomized or non-randomized and single-center or multi-center trials. Retrospective trials were categorized as registries, meta-analyses and other studies, mostly comprising of case reports or series. Study outcomes were categorized as positive or negative depending on whether the pre-specified hypothesis was met. Financial disclosures were researched for financial relationships and profit status, and accordingly categorized as government, non-profit or industry sponsored. Studies were assessed for reporting COI. Results 1,671 original articles were included in this analysis. Total number of published studies decreased by 17% from 1988 to 2008. Over 20 year period, the proportion of prospective randomized trials increased from 22 to 46% (p < 0.0001); whereas the proportion of prospective non-randomized trials decreased from 59% to 27% (p < 0.001). There was an increase in the percentage of prospective randomized multi-center trials from 11% to 41% (p < 0.001). Conversely, there was a reduction in non-randomized single-center trials from 47% to 10% (p < 0.001). Proportion of government funded studies remained constant, whereas

    The aim of this study is to provide an update as to whether authors in the orthodontic field of research currently report randomized clinical trials (RCTs) adequately as defined by the Consolidated Standards of Reporting Trials (CONSORT) statement. The American Journal of Orthodontics and Dentofacial Orthopedics (AJO-DO), Journal of Orthodontics (JO), European Journal of Orthodontics (EJO) and Angle Orthodontist (AO) were reviewed to identify all articles that reported RCTs published between January 2008 and June 2012.Reports were scored using the CONSORT 37 item checklist. A 10% random sample of the papers was scored by a second examiner to assess inter-examiner reliability of the CONSORT score. Another 10% random sample of the papers was scored a second time by the first examiner 3 months after initial data collection to test intra-examiner reliability. A total of 151 clinical trial reports have been identified out of 3335 articles in the four journals from January 2008 to June 2012.Mean CONSORT score of the four journals was 51.7%. Journal of Orthodontics achieved the highest score of 73.6% and the lowest score was achieved by AO with a score of 44.5%. Overall compliance with CONSORT increased from 47.8 to 56.3% between 2008 and 2012. Clinical trials reports represented orthodontic journals between 2008 and 2012. • CONSORT mean score ranged from 44.5 to 73.6% between journals. • CONSORT mean score increased through the period of investigation.

    Full Text Available The objective of this work is to study the relationship between journals and the members of their editorial committees who publish articles in them. The results show that editorial committee members have their articles published much faster than authors who do not belong to the committees. Furthermore, there is a lack of collaboration between members who serve on committees of different journals, when compared with that existing between committee members of the same journal. In 6 of the 10 journals analyzed the percentage of articles signed by a committee member is higher than 25%, and in three of these journals the publishing time of the articles is significantly lower than for authors who do not belong to a committee. It is possible to conclude that being part of an editorial committee is a path used by authors who wish to publish their articles in a timelier manner.

  12. Global Journalism Ethics: Widening the Conceptual Base

    2008-01-01

    Full Text Available For most of its history, journalism ethics has been highly practical in aim, in theorizing, and in application. Inquiry analyzed what was occurring inside newsrooms and its scope was parochial. Starting from the premise that a parochial approach no longer serves journalism, the study of journalism, or the public of journalism, in this paper it is argued that a major task of journalism ethics is to construct a more non-parochial ethics—a global journalism ethics informed by critical work from various disciplines and cultures. The discussion presented charts the trajectory of journalism ethics over several centuries to explain the role of parochialism and the limits of theorizing in journalism ethics. This historical perspective also serves as a foundation for outlining what a future journalism ethics might look like, if we widen the conceptual base by incorporating new knowledge of media from outside journalism ethics, and by redefining journalism ethics as a global enterprise.

    Quality of life (QoL) is known to be indicative of the level of social functioning in mental health patients. However, the research on QoL, in the field of psychiatry, is not as comprehensive as it is in other domains of medicine. The aim of this study was to review the research evidence on QoL in psychiatric patients, published in Serbian medical journals during the last decade. The research data from studies on quality of life in psychiatric patients, published in Serbian medical journals from 2000 to 2009, were obtained by searching the databases Kobson and Medline. We found eight studies on QoL in psychiatric patients published in Serbian medical journals from 2000 to 2009. The reviewed articles were focused on the comparison of QoL between psychiatric patients and healthy controls, or somatic patients, the research on the relationship of QoL and general psychopathology, and the research on QoL and medical treatment. QoL in patients suffering from mental disorders, as the outcome variable, is of a paramount interest in the follow-up treatment studies in psychiatry targeting critical issues of mental illness management strategies. QoL of psychiatric patients in Serbia is still under-researched, and it would be important to measure QoL from both a patient's and observer's (i.e. family members, friends, nursing staff, mental health professionals, etc.) perspective, in the context of social, economic, and cultural background of the patient. In the future, the studies on QoL in psychiatric patients in Serbia should also rely on "disease specific" assessment scales, which would consider particular aspects of psychopathology, and eventually follow up longitudinal course of mental illness, treatment outcome, and recovery.

    We show how a combination of virtual reality and robotics can be used to beam a physical representation of a person to a distant location, and describe an application of this system in the context of journalism. Full body motion capture data of a person is streamed and mapped in real time, onto the limbs of a humanoid robot present at the remote location. A pair of cameras in the robot's 'eyes' stream stereoscopic video back to the HMD worn by the visitor, and a two-way audio connection allows the visitor to talk to people in the remote destination. By fusing the multisensory data of the visitor with the robot, the visitor's 'consciousness' is transformed to the robot's body. This system was used by a journalist to interview a neuroscientist and a chef 900 miles distant, about food for the brain, resulting in an article published in the popular press.

  3. Did Evolution Select a Nonrandom "Alphabet" of Amino Acids?

    Science.gov (United States)

    Philip, Gayle K.; Freeland, Stephen J.

    2011-04-01

    The last universal common ancestor of contemporary biology (LUCA) used a precise set of 20 amino acids as a standard alphabet with which to build genetically encoded protein polymers. Considerable evidence indicates that some of these amino acids were present through nonbiological syntheses prior to the origin of life, while the rest evolved as inventions of early metabolism. However, the same evidence indicates that many alternatives were also available, which highlights the question: what factors led biological evolution on our planet to define its standard alphabet? One possibility is that natural selection favored a set of amino acids that exhibits clear, nonrandom properties - a set of especially useful building blocks. However, previous analysis that tested whether the standard alphabet comprises amino acids with unusually high variance in size, charge, and hydrophobicity (properties that govern what protein structures and functions can be constructed) failed to clearly distinguish evolution's choice from a sample of randomly chosen alternatives. Here, we demonstrate unambiguous support for a refined hypothesis: that an optimal set of amino acids would spread evenly across a broad range of values for each fundamental property. Specifically, we show that the standard set of 20 amino acids represents the possible spectra of size, charge, and hydrophobicity more broadly and more evenly than can be explained by chance alone.

    Background The past 3 decades have witnessed a boost in science development in China; in parallel, more and more Chinese scientific journals are indexed by the Journal Citation Reports issued by Thomson Reuters (SCI). Evaluation of the performance of these Chinese SCI journals is necessary and helpful to improve their quality. This study aimed to evaluate these journals by calculating various journal self-citation rates, which are important parameters influencing a journal impact factor. Methodology/Principal Findings We defined three journal self-citation rates, and studied these rates for 99 Chinese scientific journals, almost exhausting all Chinese SCI journals currently available. Likewise, we selected 99 non-Chinese international (abbreviated as ‘world’) journals, with each being in the same JCR subject category and having similar impact factors as their Chinese counterparts. Generally, Chinese journals tended to be higher in all the three self-citation rates than world journal counterparts. Particularly, a few Chinese scientific journals had much higher self-citation rates. Conclusions/Significance Our results show that generally Chinese scientific journals have higher self-citation rates than those of world journals. Consequently, Chinese scientific journals tend to have lower visibility and are more isolated in the relevant fields. Considering the fact that sciences are rapidly developing in China and so are Chinese scientific journals, we expect that the differences of journal self-citation rates between Chinese and world scientific journals will gradually disappear in the future. Some suggestions to solve the problems are presented. PMID:23173041

And how will we continue practicing it into the coming era? on this article I would like to think through some of the most important challenges facing the study of contemporary journalism. I’ll be drawing from my own work that has been somewhat focused on the fundamental question of what journalism is for.

    Using the free volume of van der Waals equation, Carnahan-Starling equation for hard spheres, Wilson equation for nonrandom mixing of solution, NRTL equation and our equation, several new equations of states for pure gases are derived. Using these equations, compressibility factors for pure gases are calculated and compared with Nelson-Obert generalized compressibility factor charts. The equation of states using the concept of molecular nonrandom distribution gave better results than those of molecular random distribution. This shows that the molecular nonrandom distribution makes considerable effect on the equation of states.

    Controlling for confounders is a crucial step in analytical observational studies, and multivariable models are widely used as statistical adjustment techniques. However, the validation of the assumptions of the multivariable regression models (MRMs) should be made clear in scientific reporting. The objective of this study is to review the quality of statistical reporting of the most commonly used MRMs (logistic, linear, and Cox regression) that were applied in analytical observational studies published between 2003 and 2014 by journals indexed in MEDLINE.Review of a representative sample of articles indexed in MEDLINE (n = 428) with observational design and use of MRMs (logistic, linear, and Cox regression). We assessed the quality of reporting about: model assumptions and goodness-of-fit, interactions, sensitivity analysis, crude and adjusted effect estimate, and specification of more than 1 adjusted model.The tests of underlying assumptions or goodness-of-fit of the MRMs used were described in 26.2% (95% CI: 22.0-30.3) of the articles and 18.5% (95% CI: 14.8-22.1) reported the interaction analysis. Reporting of all items assessed was higher in articles published in journals with a higher impact factor.A low percentage of articles indexed in MEDLINE that used multivariable techniques provided information demonstrating rigorous application of the model selected as an adjustment method. Given the importance of these methods to the final results and conclusions of observational studies, greater rigor is required in reporting the use of MRMs in the scientific literature.

    An important attribute of the traditional impact factor was the controversial 2-year citation window. So far, several scholars have proposed using different citation time windows for evaluating journals. However, there is no confirmation whether a longer citation time window would be better. How did the journal evaluation effects of 3IF, 4IF, and 6IF comparing with 2IF and 5IF? In order to understand these questions, we made a comparative study of impact factors with different citation time windows with the peer-reviewed scores of ophthalmologic journals indexed by Science Citation Index Expanded (SCIE) database. The peer-reviewed scores of 28 ophthalmologic journals were obtained through a self-designed survey questionnaire. Impact factors with different citation time windows (including 2IF, 3IF, 4IF, 5IF, and 6IF) of 28 ophthalmologic journals were computed and compared in accordance with each impact factor's definition and formula, using the citation analysis function of the Web of Science (WoS) database. An analysis of the correlation between impact factors with different citation time windows and peer-reviewed scores was carried out. Although impact factor values with different citation time windows were different, there was a high level of correlation between them when it came to evaluating journals. In the current study, for ophthalmologic journals' impact factors with different time windows in 2013, 3IF and 4IF seemed the ideal ranges for comparison, when assessed in relation to peer-reviewed scores. In addition, the 3-year and 4-year windows were quite consistent with the cited peak age of documents published by ophthalmologic journals. Our study is based on ophthalmology journals and we only analyze the impact factors with different citation time window in 2013, so it has yet to be ascertained whether other disciplines (especially those with a later cited peak) or other years would follow the same or similar patterns. We designed the survey questionnaire

    Prognostic research studies in anesthesiology aim to identify risk factors for an outcome (explanatory studies) or calculate the risk of this outcome on the basis of patients' risk factors (predictive studies). Multivariable models express the relationship between predictors and an outcome and are used in both explanatory and predictive studies. Model development demands a strict methodology and a clear reporting to assess its reliability. In this methodological descriptive review, we critically assessed the reporting and methodology of multivariable analysis used in observational prognostic studies published in anesthesiology journals. A systematic search was conducted on Medline through Web of Knowledge, PubMed, and journal websites to identify observational prognostic studies with multivariable analysis published in Anesthesiology, Anesthesia & Analgesia, British Journal of Anaesthesia, and Anaesthesia in 2010 and 2011. Data were extracted by 2 independent readers. First, studies were analyzed with respect to reporting of outcomes, design, size, methods of analysis, model performance (discrimination and calibration), model validation, clinical usefulness, and STROBE (i.e., Strengthening the Reporting of Observational Studies in Epidemiology) checklist. A reporting rate was calculated on the basis of 21 items of the aforementioned points. Second, they were analyzed with respect to some predefined methodological points. Eighty-six studies were included: 87.2% were explanatory and 80.2% investigated a postoperative event. The reporting was fairly good, with a median reporting rate of 79% (75% in explanatory studies and 100% in predictive studies). Six items had a reporting rate identified in the STROBE checklist: blinded evaluation of the outcome (11.9%), reason for sample size (15.1%), handling of missing data (36.0%), assessment of colinearity (17.4%), assessment of interactions (13.9%), and calibration (34.9%).

    Nurses are required to interpret and apply knowledge so communities will receive care based on best available evidence, as opposed to care that is simply based on tradition or authority. Fostering nursing students' critical appraisal skills will assist in their capacity to engage with, interpret and use best evidence. Journal clubs are frequently used approach to engage learners with research and develop critical appraisal skills. Given new flipped and blended approaches to teaching and learning there is need to rejuvenate how research is utilised and integrated within journal clubs to maximise engagement and translation of evidence. This paper provides a case study of a single site Australian university experience of transitioning a traditional physical journal club, to a social media-facilitated club within a postgraduate health subject to stimulate and facilitate engagement with the chosen manuscripts. This case study is based on our own experiences, supported by literature and includes qualitative comments obtained via student feedback surveys during November 2015. Case study. Social media-facilitated journal clubs offer an efficient way to continue developing critical appraisal skills in nursing students. The integration of a social media-facilitated journal clubs increased student attention, engagement with presented activities and overall student satisfaction within this evidence-based practice subject. Future rigorously-designed, large-scale studies are required to evaluate the impact of online journal clubs on the uptake of evidence-based practice, including those resulting in improved patient outcomes.

    Ko, Wen-Ru; Hung, Wei-Te; Chang, Hui-Chin; Lin, Long-Yau

    2014-03-01

    The study was designed to investigate the frequency of misusing standard error of the mean (SEM) in place of standard deviation (SD) to describe study samples in four selected journals published in 2011. Citation counts of articles and the relationship between the misuse rate and impact factor, immediacy index, or cited half-life were also evaluated. All original articles in the four selected journals published in 2011 were searched for descriptive statistics reporting with either mean ± SD or mean ± SEM. The impact factor, immediacy index, and cited half-life of the journals were gathered from Journal Citation Reports Science edition 2011. Scopus was used to search for citations of individual articles. The difference in citation counts between the SD group and SEM group was tested by the Mann-Whitney U test. The relationship between the misuse rate and impact factor, immediacy index, or cited half-life was also evaluated. The frequency of inappropriate reporting of SEM was 13.60% for all four journals. For individual journals, the misuse rate was from 2.9% in Acta Obstetricia et Gynecologica Scandinavica to 22.68% in American Journal of Obstetrics & Gynecology. Articles using SEM were cited more frequently than those using SD (p = 0.025). An approximate positive correlation between the misuse rate and cited half-life was observed. Inappropriate reporting of SEM is common in medical journals. Authors of biomedical papers should be responsible for maintaining an integrated statistical presentation because valuable articles are in danger of being wasted through the misuse of statistics.

  10. Reducing bias in survival under non-random temporary emigration

    Science.gov (United States)

    Peñaloza, Claudia L.; Kendall, William L.; Langtimm, Catherine Ann

    2014-01-01

    Despite intensive monitoring, temporary emigration from the sampling area can induce bias severe enough for managers to discard life-history parameter estimates toward the terminus of the times series (terminal bias). Under random temporary emigration unbiased parameters can be estimated with CJS models. However, unmodeled Markovian temporary emigration causes bias in parameter estimates and an unobservable state is required to model this type of emigration. The robust design is most flexible when modeling temporary emigration, and partial solutions to mitigate bias have been identified, nonetheless there are conditions were terminal bias prevails. Long-lived species with high adult survival and highly variable non-random temporary emigration present terminal bias in survival estimates, despite being modeled with the robust design and suggested constraints. Because this bias is due to uncertainty about the fate of individuals that are undetected toward the end of the time series, solutions should involve using additional information on survival status or location of these individuals at that time. Using simulation, we evaluated the performance of models that jointly analyze robust design data and an additional source of ancillary data (predictive covariate on temporary emigration, telemetry, dead recovery, or auxiliary resightings) in reducing terminal bias in survival estimates. The auxiliary resighting and predictive covariate models reduced terminal bias the most. Additional telemetry data was effective at reducing terminal bias only when individuals were tracked for a minimum of two years. High adult survival of long-lived species made the joint model with recovery data ineffective at reducing terminal bias because of small-sample bias. The naïve constraint model (last and penultimate temporary emigration parameters made equal), was the least efficient, though still able to reduce terminal bias when compared to an unconstrained model. Joint analysis of several

    Directory of Open Access Journals (Sweden)

    Francisco J. Bonilla-Escobar

    2013-12-01

    Full Text Available Background: Bibliometric or scientometric studies are methodological fields focused on the structural analysis of the information contained in scientific publication and generate indicators that help identify challenges and achievements in research. We aimed to characterize the publications that used this method authored by medical students in Latin America. Methods: We reviewed articles that performed a bibliometric analysis and were published in a Latin American medical student journal, between 2001 and 2012. We analyzed the characteristics of the articles, authors and references. Linear simple regression and Pearson correlation coefficient (PCC were developed to identify trends and correlations with 95% confidence. Results: There were 12 volumes of the journal available online, with a total of 236 articles. Of these, 13 (5.5% were bibliometric studies: five original articles, four letters to the editor, two editorials, one short communication, and one review. There was a positive significant relationship between time (years and number of publications (ß1=0.16, p=0.03, PCC=63%, and citations of each article (not significant, ß1=1.3, p=0.09, PCC=49%. Conclusion: There was an increase in the number of bibliometric publications after 2008, possibly influenced by a popularization of these types of studies in Latin America. Findings should motivate new and collaborative studies in this field. Moreover, it will be necessary to clarify publication areas of interest of medical students around the world.

  17. Technological innovation and convergent journalism. Case study on the transformation process of Bavaria’s public broadcasting service

    Directory of Open Access Journals (Sweden)

    Klaus MEIER

    2017-01-01

    Full Text Available As a consequence of technological innovations and their social utilisation, media organisations and newsrooms are undergoing a fundamental transformation process. This article analyses the interrelations between technological innovations and the challenges of convergent journalism. Studies conducted on newsroom convergence to date set out from one-sided influences: They investigated the extent to which technical innovations determine the newsrooms, or whether journalistic structures and long-range trends are so strong as to largely obstruct the adoption of new technologies in journalism. Therefore technology — especially in studies carried out on newsroom convergence — is considered as an influencing factor on somehow resisting or non-resisting newsrooms. We broaden the scope of this investigation by considering that any such influence might not come exclusively from technology, but that impulses can come also from innovative newsrooms: technological gaps, wishes and obstacles are identified from the journalist's viewpoint and brought to the attention of the developers of newsroom technologies — on the basis of empirical research findings from a case study of Bavaria’s public broadcasting service, Bayerischer Rundfunk (BR. With its 5.000 employees, BR is one of Germany's largest media organisations. It is undergoing a fundamental and long-term convergence process. A variety of gaps, problems and wishes came to light from 25 in-depth interviews with journalists working on innovative projects. For example, criticism is expressed of complicated, partly unknown or non-existent networking of cross-media production systems. There is a desire for the increased use of consumer devices like smartphones in professional news production. There exists a creative potential for innovative solutions, but these are not comprehensively evaluated. To date, there has been no systematic implementation of the findings of innovative media projects in everyday

  18. Microstructural descriptors and cellular automata simulation of the effects of non-random nuclei location on recrystallization in two dimensions

    Directory of Open Access Journals (Sweden)

    Paulo Rangel Rios

    2006-06-01

    Full Text Available The effect of non-random nuclei location and the efficiency of microstructural descriptors in assessing such a situation are studied. Cellular automata simulation of recrystallization in two dimensions is carried out to simulate microstrutural evolution for nuclei distribution ranging from a periodic arrangement to clusters of nuclei. The simulation results are compared in detail with microstrutural descriptors normally used to follow transformation evolution. It is shown that the contiguity is particularly relevant to detect microstructural deviations from randomness. This work focuses on recrystallization but its results are applicable to any nucleation and growth transformation.

    Johnson, E D; Sievert, M C; McKinin, E J

    1995-01-01

    It has been established that subject searches of medical full-text databases obtain higher recall than subject searches in a bibliographic database. In this study we attempted to determine if the same rule might apply when searching for a non-subject parameter such as study design. A simultaneous search of bibliographic and full-text records from the New England Journal of Medicine provided data on the number of items retrieved by each kind of search. Filtering strategies were created for 5 different study types: randomized controlled trials, other clinical trials and prospective studies, cohort studies, longitudinal and follow-up studies, and multicenter studies. The point of the study was to compare the numbers of items retrieved from the bibliographic database, MEDLINE, and those retrieved from the full-text version of NEJM, and to examine the unique access points available in each file. For all the study types the full-text file retrieved a larger number of records than MEDLINE, most of which were retrieved because of methodology terms found in the text but not in the title or abstract. In MEDLINE, descriptors and publication types, two value-added fields supplied by indexers, retrieved 11-89% more than title and abstract alone.

  4. Molecular cloaking of H2A.Z on mortal DNA chromosomes during nonrandom segregation.

    Science.gov (United States)

    Huh, Yang Hoon; Sherley, James L

    2011-10-01

    Although nonrandom sister chromatid segregation is a singular property of distributed stem cells (DSCs) that are responsible for renewing and repairing mature vertebrate tissues, both its cellular function and its molecular mechanism remain unknown. This situation persists in part because of the lack of facile methods for detecting and quantifying nonrandom segregating cells and for identifying chromosomes with immortal DNA strands, the cellular molecules that signify nonrandom segregation. During nonrandom segregation, at each mitosis, asymmetrically self-renewing DSCs continuously cosegregate to themselves the set of chromosomes that contain immortal DNA strands, which are the oldest DNA strands. Here, we report the discovery of a molecular asymmetry between segregating sets of immortal chromosomes and opposed mortal chromosomes (i.e., containing the younger set of DNA template strands) that constitutes a new convenient biomarker for detection of cells undergoing nonrandom segregation and direct delineation of chromosomes that bear immortal DNA strands. In both cells engineered with DSC-specific properties and ex vivo-expanded mouse hair follicle stem cells, the histone H2A variant H2A.Z shows specific immunodetection on immortal DNA chromosomes. Cell fixation analyses indicate that H2A.Z is present on mortal chromosomes as well but is cloaked from immunodetection, and the cloaking entity is acid labile. The H2A.Z chromosomal asymmetry produced by molecular cloaking provides a first direct assay for nonrandom segregation and for chromosomes with immortal DNA strands. It also seems likely to manifest an important aspect of the underlying mechanism(s) responsible for nonrandom sister chromatid segregation in DSCs.

    2015-01-01

    Scientific journals are the repositories of the gradually accumulating knowledge of mankind about the world surrounding us. Just as our knowledge is organised into classes ranging from major disciplines, subjects and fields to increasingly specific topics, journals can also be categorised into groups using various metrics. In addition to the set of topics characteristic for a journal, they can also be ranked regarding their relevance from the point of overall influence. One widespread measure is impact factor, but in the present paper we intend to reconstruct a much more detailed description by studying the hierarchical relations between the journals based on citation data. We use a measure related to the notion of m-reaching centrality and find a network which shows the level of influence of a journal from the point of the direction and efficiency with which information spreads through the network. We can also obtain an alternative network using a suitably modified nested hierarchy extraction method applied ...

    This cross-sectional study aimed at evaluating the abstracts of all articles published in the 'Jornal Brasileiro de Odontopediatria e Odontologia do Bebê' in order to collect data on the study design used, the most researched topics and the Brazilian states with the highest scientific production. Copies were made of the abstracts of each article, totaling 572 abstracts. Data categorization was done by two trained and independent reviewers. The results showed that the most used study design were case report (33%) and cross-sectional study (30%). On the other hand, there were only 2.5% of randomized clinical trials and no systematic review or meta-analysis. The most researched topics were cariology (15%) and restorative dentistry / dental materials (10%). The state with the greatest number of publications was São Paulo (40%), followed by Rio de Janeiro (17%). It was concluded that the majority of the articles published referred to studies with a low potential to establish scientific evidence, indicating a need for conducting research based on better quality methodology. Moreover, it was found that the assessed literature reflected the trends observed in the clinical practice of Pediatric Dentistry in Brazil.

    The impact factor has become the subject of widespread controversy. It has gradually developed to mean both journal and author impact. The emphasis on impact factors obscures the main purpose of bibliographic databases created at the Institute for Scientific Information. I will here show how two of these databases, Journal Citation Reports and the Journal Performance Indicators, can be used to study scientific journals and the articles they publish, as well as the evolution of scientific fields.

    The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement is a set of recommendations about what should be included in a more accurate and complete description of observational studies. The aim was to assess the quality of reporting of cross-sectional studies by evaluating the extent to which they adhere to the STROBE statement. This study has a cross-sectional design. All the articles published as original articles in Indian Journal of Community Medicine from January 2010 to September 2011 were downloaded from the journal website. A total of 96 articles were downloaded out of which 80 were found to have a cross-sectional design. Variables were: (1) Percentage of STROBE items included in a report and (2) percentage of articles reporting each item in the STROBE checklist. Data analysis was done by descriptive statistics using frequencies and percentages. A total of 80 articles were evaluated. About 46% (37/80) articles reported 12-15 items of the STROBE checklist. Bias, nonparticipants and reasons for nonparticipation, other analyses done, generalizability, and source of funding were reported by < 25% of studies. The most frequently reported items of the checklist were summary of what was done and what was found in the abstract, background/rationale, objectives, setting, outcome data, key results in discussion, interpretation of results. None of the articles reported all items of the STROBE checklist. This study reveals that the quality of reporting cross-sectional studies in Indian Journal of Community Medicine is not satisfactory and there is room for improvement.

  10. A new non-randomized model for analysing sensitive questions with binary outcomes.

    Science.gov (United States)

    2007-10-15

    We propose a new non-randomized model for assessing the association of two sensitive questions with binary outcomes. Under the new model, respondents only need to answer a non-sensitive question instead of the original two sensitive questions. As a result, it can protect a respondent's privacy, avoid the usage of any randomizing device, and be applied to both the face-to-face interview and mail questionnaire. We derive the constrained maximum likelihood estimates of the cell probabilities and the odds ratio for two binary variables associated with the sensitive questions via the EM algorithm. The corresponding standard error estimates are then obtained by bootstrap approach. A likelihood ratio test and a chi-squared test are developed for testing association between the two binary variables. We discuss the loss of information due to the introduction of the non-sensitive question, and the design of the co-operative parameters. Simulations are performed to evaluate the empirical type I error rates and powers for the two tests. In addition, a simulation is conducted to study the relationship between the probability of obtaining valid estimates and the sample size for any given cell probability vector. A real data set from an AIDS study is used to illustrate the proposed methodologies.

    Full Text Available Ceramic is the oldest synthetic material created by the mankind and has been present in human societies from around ten thousand years ago. During the last few decades, within the research field of Archaeometry, the study of archaeological and historical ceramic materials has experienced a significant increase in the application of chemical-physical techniques to obtain information on technology and production of these materials in the past. This paper presents the results obtained in a bibliometric study undertaken on 589 articles published on this subject in JCR journals and conference proceedings during the last decade (2000-2010. The main purpose of this research was to address the recent evolution and trends of this kind of investigations. The parameters analyzed were: date of publication, type of journal, topic, cultural-chronological classification of materials studied, origin country of authors, and analytical techniques used. Resulting data indicated a continual, stable, and growing publication rate on the subject in journals and conference proceedings of the three JCR indexes, namely SCI, AHCI, and SSCI, which evidences a high level of interdisciplinarity. Authors from Europe and the United States carried out the majority of contributions.

    Full Text Available The objective of this article is to compare the self-regulatory systems of the journalistic profession in Austria, Germany, Denmark, Estonia, Spain, France and Poland. Based on the analysis of the different cases and situations in these seven countries, we offer a comparative analysis of the existence of: ethical codes, pro-consumers associations, print and audiovisual press councils, level of organization and unionism among journalists. The results reveal deficiencies in the European systems as well as progressions in the implementation of self-regulation tools in the journalistic profession, mainly in the field of print and audiovisual media. In most European countries under study, online newspapers lack self-regulatory tools, except for the regulation coming from their parent print or broadcast media companies.

    Statistical power (and conversely, Type II error) is often ignored by biologists. Power is important to consider in the design of studies, to ensure that sufficient resources are allocated to address a hypothesis under examination. Deter- mining appropriate sample size when designing experiments or calculating power for a statistical test requires an investigator to consider the importance of making incorrect conclusions about the experimental hypothesis and the biological importance of the alternative hypothesis (or the biological effect size researchers are attempting to measure). Poorly designed studies frequently provide results that are at best equivocal, and do little to advance science or assist in decision making. Completed studies that fail to reject Ho should consider power and the related probability of a Type II error in the interpretation of results, particularly when implicit or explicit acceptance of Ho is used to support a biological hypothesis or management decision. Investigators must consider the biological question they wish to answer (Tacha et al. 1982) and assess power on the basis of biologically significant differences (Taylor and Gerrodette 1993). Power calculations are somewhat subjective, because the author must specify either f or the minimum difference that is biologically important. Biologists may have different ideas about what values are appropriate. While determining biological significance is of central importance in power analysis, it is also an issue of importance in wildlife science. Procedures, references, and computer software to compute power are accessible; therefore, authors should consider power. We welcome comments or suggestions on this subject.

  19. The generation of meanings on TV journalism: a study of the public health in the Jornal Nacional

    2013-08-01

    Full Text Available The picture is likely to produce senses that generate meanings, mainly in the culture media, taken as the products of the media, with their respective vehicles. These are mechanisms for building values, beliefs and customs. Therefore, the television news is an important space for the construction of senses that create meaning for the viewer. In this context, the objective of this dissertation is to identify the elements of the message of TV news in reporting on public health in the Jornal Nacional (JN, of Globo Television Network, pointing the senses produced. The methodology of this study adopts the instrument of data collection, the technique of valence (positive, negative, neutral and balanced. The reports of JN on public health were classified by category (MedicalCareHospital, Program / Project Health, Complementary Health, Outpatient Medical Care, Drugs, Death, Disease, Health Financing, the format (Report, Full Report, Special Report, Series, Note Hedged and the duration. In all, 42 were classified and analyzed raw, aired by National Journal in 2011, with a total of 133 minutes and 49 seconds.

The reporting formats are used (14 and Full Feature (12. The approach of the National Journal to public health, mostly negative, is symbolic and serves on the representation bias, producing meanings that are decoded by the viewer to construct different meanings. The confirmation of the three hypotheses of this study shows that the Jornal Nacional builds negative meanings in relation to the Brazilian public health when first, mainly emphasizes facts and bad events, and second, it addresses public health in factual events, treating them superficially and decontextualized from the

  1. Assessing the impacts of nonrandom seed dispersal by multiple frugivore partners on plant recruitment.

    Science.gov (United States)

    Razafindratsima, Onja H; Dunham, Amy E

    2015-01-01

    Directed dispersal is defined as enhanced dispersal of seeds into suitable microhabitats, resulting in higher recruitment than if seeds were dispersed randomly. While this constitutes one of the main explanations for the adaptive value of frugivore-mediated seed dispersal, the generality of this advantage has received little study, particularly when multiple dispersers are involved. We used probability recruitment models of a long-lived rainforest tree in Madagascar to compare recruitment success under dispersal by multiple frugivores, no dispersal, and random dispersal. Models were parameterized using a three-year recruitment experiment and observational data of dispersal events by three frugivorous lemur species that commonly disperse its seeds. Frugivore-mediated seed dispersal was nonrandom with respect to canopy cover and increased modeled per-seed sapling recruitment fourfold compared to no dispersal. Seeds dispersed by one frugivore, Eulemur rubriventer, had higher modeled recruitment probability than seeds dispersed randomly. However, as a group, our models suggest that seeds dispersed by lemurs would have lower recruitment than if dispersal were random. Results demonstrate the importance of evaluating the contribution of multiple frugivores to plant recruitment for understanding plant population dynamics and the ecological and evolutionary significance of seed dispersal.

    2001-06-01

    The authors conducted a descriptive, archival study of adolescent (mass murderers-subjects who intentionally killed three or more victims in one event-to identify demographic, clinical, and forensic characteristics. A nonrandom sample of convenience of adolescent mass murderers was utilized. Thirty-four subjects, acting alone or in pairs, committed 27 mass murders between 1958 and 1999. The sample consisted of males with a median age of 17. A majority were described as "loners" and abused alcohol or drugs; almost half were bullied by others, preoccupied with violent fantasy, and violent by history. Although 23% had a documented psychiatric history, only 6% were judged to have been psychotic at the time of the mass murder. Depressive symptoms and historical antisocial behaviors were predominant. There was a precipitating event in most cases--usually a perceived failure in love or school--and most subjects made threatening statements regarding the mass murder to third parties. The majority of the sample clustered into three types: the family annihilator, the classroom avenger, and the criminal opportunist. The adolescent mass murderer is often predatorily rather than affectively violent and typically does not show any sudden or highly emotional warning signs. Although the act of mass murder is virtually impossible to predict because of its extremely low frequency, certain clinical and forensic findings can alert the clinician to the need for further, intensified primary care, including family, school, community, law enforcement, and mental health intervention.

  3. Next generation sequencing and FISH reveal uneven and nonrandom microsatellite distribution in two grasshopper genomes.

    Simple sequence repeats (SSRs), also known as microsatellites, are one of the prominent DNA sequences shaping the repeated fraction of eukaryotic genomes. In spite of their profuse use as molecular markers for a variety of genetic and evolutionary studies, their genomic location, distribution, and function are not yet well understood. Here we report the first thorough joint analysis of microsatellite motifs at both genomic and chromosomal levels in animal species, by a combination of 454 sequencing and fluorescent in situ hybridization (FISH) techniques performed on two grasshopper species. The in silico analysis of the 454 reads suggested that microsatellite expansion is not driving size increase of these genomes, as SSR abundance was higher in the species showing the smallest genome. However, the two species showed the same uneven and nonrandom location of SSRs, with clear predominance of dinucleotide motifs and association with several types of repetitive elements, mostly histone gene spacers, ribosomal DNA intergenic spacers (IGS), and transposable elements (TEs). The FISH analysis showed a dispersed chromosome distribution of microsatellite motifs in euchromatic regions, in coincidence with chromosome location patterns previously observed for many mobile elements in these species. However, some SSR motifs were clustered, especially those located in the histone gene cluster.

    Full Text Available Abstract Background Journal advertising is used by pharmaceutical companies to disseminate medicine information to doctors. The quality of claims, references and the presentation of risk results in Australia and the US has been questioned in several studies. No recent evidence is available on the quality of claims, references and the presentation of risk results in journal advertising in Australia and the US and no Malaysian data have been published. The aim of this study was to compare the quality of claims, references and the presentation of risk results in journal advertising in these three countries. Methods A consecutive sample of 85 unique advertisements from each country was selected from journal advertising published between January 2004 to December 2006. Claims, references and the presentation of risk results in medical journal advertising were compared between the three countries. Results Less than one-third of the claims were unambiguous claims (Australia, 30%, Malaysia 17%, US, 23%. In Malaysia significantly less unambiguous claims were provided than in Australia and the US (P Conclusions The majority of claims were vague suggesting poor quality of claims in journal advertising in these three countries. Evidence from a randomized controlled trial, systematic review or meta- analysis was commonly cited to support claims. However, the more frequent use of data that have not been published and independently reviewed in the US compared to Australia and Malaysia raises questions on the quality of references in the US. The use of relative rather than absolute benefits may overemphasize the benefit of medicines which may leave doctors susceptible to misinterpreting information.

    The paper presents a two-sided approach to establish understanding of the cavitation phenomenon in dynamically loaded journal bearings, more specifically the engine bearings of large two-stroke marine diesel engines. One disadvantage of the journal bearing is the converging-diverging geometry...... making it prone to cavitation which again affects the load carrying capacity of the bearing. In combustion engines the journal bearing plays a vital role especiallyas main and crosshead bearings transmitting the combustion forces. Those forces vary highly during one combustion cycle which is further....... Validation of the results is done against the Ruston and Hornsby 6VEB-X Mk III engine. Besides the numerical investigations a cavitation test rig has been developed. With this rig it is possible to generate cavitation under controlled conditions in terms ofload/eccentricity and rotational speed...

    Full Text Available Journal writing can be a creative adjunct to psychotherapy. This article will describe a qualitative study of the experiences of journal writers. Each participant’s narrative illustrates the integration of Winnicott’s transitional phenomena, Freeman’s four stages of epiphanies, and Kegan’s adult developmental stages through journal writing. The central findings of this research are that the experience of the participants can be identified in the following three categories: therapeutic experience,meditative experience, and a transformative experience. Journal writing can be adapted by psychotherapists, as an adjunct to therapy, to aid clients in elaborating their stories, listening within, identifying epiphanies, and moving forward in the change process.This article will present a case study of one of the narratives from this research.

    Cadet de Gassicourt wrote a brief Eloge of Fourcroy in January 1810 as he died in December of 1809. Fourcroy had a major role concerning the new ideas on the place of pharmacy at the beginning of the 19th century. Fourcroy has had a key influence for the start of several pharmaceutical journals that wanted to emphasize the link between the new chemistry and pharmacy. None of these journals created with him will survive and one has to wait for 1909 to see the creation, without Fourcroy, of a new pharmaceutical journal, the "Journal de Pharmacie" that will become "Journal de Pharmacie et des Sciences accessoires", then "Journal de Pharmacie et de Chimie", before taking the name of"Annales Pharmaceutiques Françaises", the present official journal of the French Academy of Pharmacy. In spite of the essential role of Fourcroy at the start of pharmaceutical journals, Cadet did not even mention it in his Eloge of 1810.
