Number Of Publications In Journals Research Articles

A bibliometric research in the tourism, leisure and hospitality fields

This paper presents a study of the most cited papers, the most productive and influential institutions and countries, and the most influential authors in the tourism, leisure, and hospitality fields. The number of publications in journals focused on these areas has increased exponentially over the past 40 years. This paper examines the fundamental contributions in these areas using a bibliometric approach. This paper also uses the visualization of similarities to graphically map the main topics and keywords. No study has examined all journals indexed in the Web of Science in these fields over a period as wide as the one considered in this study. This study is valuable for several reasons. It can help scholars and researchers to identify the countries and institutions with the most potential to develop and share research, as well as where it would be interesting to carry out their doctoral studies and develop their careers.

Guest Editorial: Special Section on Predictive Control in Power Electronics, Electrical Drives and Industrial Applications

The features and potential of predictive control techniques in power electronics applications have been demonstrated and widely studied during the last 15 years. The most remarkable advantages are the intuitive control scheme, great flexibility to cover a variety of degrees of freedom, and the straight-forward incorporation of nonlinear variables and constraints. Although this proposal with very attractive characteristics dates back to the 1970s, the experimental validation has only been possible recently, thanks to the development of modern digital controllers due to the relatively high computational burden associated with this method. The great effort of the researchers enabled a large number of publications in journals and dedicated conferences that has positioned this strategy as a viable alternative to the classical controllers. Thus, implementations based on this approach in proposals such as variable-speed drives, current, voltage, and power regulation, renewable energy generation systems, microgrids, energy storage, or electric vehicles (EVs) can be found in the literature. It is expected that the pace of developments with the predictive control keeps the current trend, because of the great opportunities in the research and industrial fields.

A statistical approach to identify, monitor, and manage incomplete curated data sets

BackgroundMany biological knowledge bases gather data through expert curation of published literature. High data volume, selective partial curation, delays in access, and publication of data prior to the ability to curate it can result in incomplete curation of published data. Knowing which data sets are incomplete and how incomplete they are remains a challenge. Awareness that a data set may be incomplete is important for proper interpretation, to avoiding flawed hypothesis generation, and can justify further exploration of published literature for additional relevant data. Computational methods to assess data set completeness are needed. One such method is presented here.ResultsIn this work, a multivariate linear regression model was used to identify genes in the Zebrafish Information Network (ZFIN) Database having incomplete curated gene expression data sets. Starting with 36,655 gene records from ZFIN, data aggregation, cleansing, and filtering reduced the set to 9870 gene records suitable for training and testing the model to predict the number of expression experiments per gene. Feature engineering and selection identified the following predictive variables: the number of journal publications; the number of journal publications already attributed for gene expression annotation; the percent of journal publications already attributed for expression data; the gene symbol; and the number of transgenic constructs associated with each gene. Twenty-five percent of the gene records (2483 genes) were used to train the model. The remaining 7387 genes were used to test the model. One hundred and twenty-two and 165 of the 7387 tested genes were identified as missing expression annotations based on their residuals being outside the model lower or upper 95% confidence interval respectively. The model had precision of 0.97 and recall of 0.71 at the negative 95% confidence interval and precision of 0.76 and recall of 0.73 at the positive 95% confidence interval.ConclusionsThis method can be used to identify data sets that are incompletely curated, as demonstrated using the gene expression data set from ZFIN. This information can help both database resources and data consumers gauge when it may be useful to look further for published data to augment the existing expertly curated information.

A Bibliometric Analysis of Lodging-Context Research From 1990 to 2016

This study evaluates lodging-context research by addressing the trend in the number of journal publications and the most prolific contributors from 1990 to 2016. To this end, data were collected from 16 leading academic journals. The study results suggest that the number of lodging-context articles from 1990 to 2016 increased significantly and that among the 16 leading journals analyzed, the International Journal of Hospitality Management and the International Journal of Contemporary Hospitality Management were the two most productive journals in publishing lodging-context–related articles. Contributors were identified according to author, institution, and country. Regarding lodging operations classifications, hotels appeared to be the most researched organizations while marketing was found to be the most studied research topic, followed by strategic management. This is the first study offering a bibliometric analysis of lodging-context research in our field.

Beyond ‘charting outcomes’ in the radiation oncology match: analysis of self-reported applicant data

ABSTRACTThe Charting Outcomes resource is useful in gauging an applicant’s competiveness for a given specialty. However, many variables are not reported in Charting Outcomes that may influence an applicant’s ability to match. A significant proportion of applicants record their experiences in an anonymous, self-reported applicant spreadsheet. We analyzed factors associated with a successful match using this dataset to test the hypothesis that research productivity and high academic performance correlates with success rates. A retrospective analysis of “RadOnc Interview Spreadsheet” for the 2015, 2016, and 2017 radiation oncology match was performed. Data were accessed via studentdoctor.net. Board scores, research characteristics, Sub-I participation, and interview invitation rates were available. Mann-Whitney U, Kruskal-Wallis, and chi-square tests were used for statistical analysis. When possible, results were compared to those reported in the National Residency Match Program’s “Charting Outcomes” report. A total of 158 applicants were examined for the applicant characteristics. Applicants applied to a median of 61 programs and received a median of 14 interviews. The mean step 1 score was 248 (range: 198 to 272) and most were in the highest grade point average quartile (68.3%). 21.7% participated in additional research year(s), and 19% obtained a PhD. The majority of applicants took three radiation oncology electives (48.7%). On multivariate analysis, alpha-omega-alpha (AOA) honors society status (p=0.033), participating in a research year (p=0.001) and number of journal publications (p=0.047) significantly correlated with higher interview invitation rates. In summary, this study identifies important considerations for radiation oncology applicants that have not been previously reported, such as induction into AOA and number of journal publications.

Диверсификация системы высшего образования в свете проблем научных коммуникаций

The article analyzes the problems of diversification of the higher education system in the light of the problems of scientific communications.With regard to the purpose of this study, as a key point was chosen the analysis of research activities of domestic universities and in particular-publication activity, as one of the criteria for assessing the effectiveness of research activities of higher education institutions. The author concludes that the role of Universities in the training of scientific personnel in Russia is growing. If this trend continues, we can say that the domestic trend of diversification of the education system, have full or almost full compliance with global trends, where the training of scientific personnel is conducted mainly in higher education. Based on the analysis of statistical material, it is noted that the number of publications in journals of Russia and other post-Soviet States indexed in the international citation databases Scopus and Web of Science Core Collection is small compared to other countries.

ELECTROLYTIC PLASMA POLISHING OF COPPER

Modern industrial technological processes require special preparation of metal surfaces. Currently, there are different methods of surface treatment of metal. Among them, it is possible to distinguish the method of electrolytic-plasma polishing (PEP– plasma electrolytic polishing) is distinguished as an innovative, due to its ecological properties, low energy consumption per unit of surface to be processed, high speed of modification and the possibility of processing parts of complex geometric shape. The main advantage of this method of surface modification is its ecological purity, which makes it possible to apply this technology to the food and pharmaceutical industry. Despite the large number of journal publications, electrolytic plasma polishing remains an innovative surface modification method that needs to be thoroughly studied in order to improve understanding of physical processes and optimize the surface modification process. The process of obtaining electrolytic plasma polishing of copper products in a solution of ammonium sulfate with the addition of sulfuric acid is considered in the paper. The experiment was divided into two stages. At first, the samples were treated for 600 seconds each for the obtain of temperature characteristics, with a strong correlation between the load current and the electrolyte temperature was observed. Dependence of the current on the temperature of the electrolyte showed four different modes of treatment. One of the modes showed the best results. During the second series of experiments, the processing of objects from 30 to 600 seconds. As a result of the conducted studies, optimal regimes for polishing copper objects were obtained.

A cross sectional observational study of research activity of allied health teams: is there a link with self-reported success, motivators and barriers to undertaking research?

BackgroundTeam-based approaches to research capacity building (RCB) may be an efficient means to promote allied health research participation and activity. In order to tailor such interventions, a clearer understanding of current patterns of research participation within allied health teams is needed. Different self-report measures exist which evaluate a team’s research capacity and participation, as well as associated barriers and motivators. However, it remains unclear how such measures are associated with a team’s actual research activity (e.g., journal publications, funding received). In response, this observational study aimed to identify the research activity, self-reported success, and motivations and barriers to undertaking research of eight allied health professional (AHP) teams and to explore whether any relationships exist between the self-reported measures and actual research activity within each team.MethodsA total of 95 AHPs from eight teams completed the research capacity and culture survey to evaluate team success, barriers and motivators to undertaking research, and an audit of research activity from January 2013 to August 2014 was undertaken within each team. Kendell’s correlation coefficients were used to determine the association between research activity (i.e., number of journal publications, ethically approved projects and funding received) and the self-reported measures.ResultsSeven out of eight teams rated their teams as having average success in research and demonstrated some form of research activity including at least two ethically approved projects. Research activity varied between teams, with funding received ranging from $0 to over $100,000, and half the teams not producing any journal publications. Team motivators demonstrated a stronger association with research activity compared to barriers, with the motivator “enhancing team credibility” being significantly associated with funding received. No significant association between self-reported research success and actual research activity was identified.ConclusionsPreliminary findings suggest that self-report measures of research success may not always correspond to actual research activity, and a combination of both these measures may be useful when planning RCB interventions. Variation in activity between teams and organisations should also be considered when tailoring RCB interventions. Reinforcing intrinsically motivating rewards of research may also be useful in promoting research participation for some teams.

The Disaster of the Impact Factor

Journal impact factor (IF) is a value calculated annually based on the number of times articles published in a journal are cited in two, or more, of the preceding years. At the time of its inception in 1955 (Garfield 1955), the inventor of the impact factor did not imagine that 1 day his tool would become a controversial and abusive measure, as he confessed 44 years later (Garfield 1999). The impact factor became a major detrimental factor of quality, creating huge pressures on authors, editors, stakeholders and funders. More tragically, in some countries the number of publications in journals with ‘‘high impact factors’’ condition the allocation of government funding for entire institutions (Plos Medicine Editorial 2006). Based on the assumption that IF reflects scientific quality, the impact factor produces a widespread impression of prestige and reputation, though no experimental data support this hypothesis (Brembs et al. 2013). The impact factor was originally conceived as a bibliometric assessment tool for publishers and librarians to provide helpful information for subscription and library collection purposes, but over the years, it has been used abusively to assess the quality of not only journals, universities, and institutions, but also individuals and countries to promote or to ‘‘denigrate’’. Its deficiencies and perverse effects are tangibly harmful that make one wonders why such a biased tool continues to exist in science. Apart from technical and business-oriented goals (Abbasi 2007, Seglen 1997), the journal impact factors suffer from two important flaws, often neglected by researchers, that need to be highlighted due to their intrinsic contradiction with fundamental scholarly ethics. First, if an article on the subject of impact factors (based on the arithmetic mean used in the calculation of impact factor) is submitted to one of the so-called ‘‘high impact factor’’ journals, the submitted article would be immediately rejected. The editors and/or reviewers would argue that the statistical approach is biased due to

Research Publication Output by Academicians in Public and Private Universities in Malaysia

The number of publication has been one of the measurement values in the performance evaluation for higher education academicians. Over the years, the obligation to publish has amplified to not just on getting published but also on getting published in high quality journal whereby the quality ranking is determined by publication categories. This paper gives an account on the publication output on Scopus by the Malaysian private and the public universities in 2010. The study employed a query search on the Malaysian universities affiliation using Scopus database. The result of the search was tabulated and narrowed to journal publications and the other types of publication such as reviews, proceedings and letters were omitted. The number of journal publications by each university was listed out and comparison on the average was made. Comparison was made between the average number of publications by the private and the public universities. Findings show that the spur on publishing among Malaysian universities has taken effect. The study found that the Malaysian private universities published a distinctively smaller number of documents in Scopus compared to the public universities. The percentage for publication of journal article from the overall Scopus publication type journal articles published by the private universities was also smaller compared to the public universities. In other words, compared to the public universities, the authors in the Malaysian private universities had lower inclination to publish journal articles and were more likely to publish in conference proceedings, reviews and articles in press. The discussion section explores the reasons for these differences and presents the possible trending on the issue of publication in Malaysia.

Distribution of Scholarly Publications Among Academic Radiology Departments

The aim of this study was to determine whether the distribution of publications among academic radiology departments in the United States is Gaussian (ie, the bell curve) or Paretian. The search affiliation feature of the PubMed database was used to search for publications in 3 general radiology journals with high Impact Factors, originating at radiology departments in the United States affiliated with residency training programs. The distribution of the number of publications among departments was examined using χ(2) test statistics to determine whether it followed a Pareto or a Gaussian distribution more closely. A total of 14,219 publications contributed since 1987 by faculty members in 163 departments with residency programs were available for assessment. The data acquired were more consistent with a Pareto (χ(2) = 80.4) than a Gaussian (χ(2) = 659.5) distribution. The mean number of publications for departments was 79.9 ± 146 (range, 0-943). The median number of publications was 16.5. The majority (>50%) of major radiology publications from academic departments with residency programs originated in <10% (n = 15 of 178) of such departments. Fifteen programs likewise produced no publications in the surveyed journals. The number of publications in journals with high Impact Factors published by academic radiology departments more closely fits a Pareto rather than a normal distribution.

Die Entrepreneurshipforschung in Deutschland, Österreich und der Schweiz. Eine Resonanzanalyse (Entrepreneurship Research in Germany, Austria, and Switzerland: A Resonance Analysis)

Over the last decades the number of journal publications in entrepreneurship research has increased dramatically. To analyze the perception of these studies, the present paper suggests a relative measure – the so-called resonance factor (RF) –, which puts a paper’s citations in relation to the number of expected citations of the average paper of the same age. We apply this resonance factor to 257 entrepreneurship studies published between 1997 and 2007 and the respective Google Scholar citations they achieved until 2010. All studies included in the sample were authored by researchers from Germany, Austria, and Switzerland. The study identifies trends in publications and discusses – based on the resonance factor – the most important contributions over the inspected time period in four areas of entrepreneurship research, i.e. entrepreneurial opportunities, the entrepreneurial personality, organization and management as well as environmental influences on entrepreneurship.

Quantification in ethnobotanical research: an overview of indices used from 1995 to 2009

Over the last few decades, local knowledge has begun to be studied by ethnobotanists using quantitative analyses to assess the relationship between biological and cultural diversity, and the relative importance of natural resources for the local population. A considerable number of published articles have proposed these quantitative analyses, necessitating discussion and analysis of the commonly employed quantitative techniques. This study examines two central issues: the nature of quantitative research in ethnobotany and the use of quantitative indices in ethnobotanical research. A literature review was completed consisting of books, reviews, articles and editorials in the main international periodicals in the areas of ethnobiology and ethnoecology. Scientific search sites were consulted, and a database was compiled and analyzed. The analysis of 64 papers and four books constituted the basis for this work. The United States produce the greatest number of publications in journals in this field (65%). A total of 87 different quantitative techniques was recorded. This work does not claim to provide a census of all the publications on the subject, but rather intends to present a panorama on the current state of quantification in ethnobotany.

Visibilidade em coloproctologia está correlacionada com atividade em pesquisa

INTRODUÇÃO: O objetivo do presente estudo foi avaliar a influencia da atividade médica em pesquisa, com a exposição que o coloproctologista tem nos congressos da Sociedade Brasileira de Coloproctologia (SBCP). MÉTODOS: Comparamos o número de publicações em revistas indexadas ao Medline e Lilacs de cada palestrante dos últimos cinco congressos da SBCP, com o número de publicações de médicos sócios não palestrantes, selecionados aleatoriamente. A pesquisa incluiu o ano de 1965 até 2005, respeitando o mesmo tempo de formado e estado de atuação profissional. RESULTADOS: Foram selecionados um total de 13 conferencistas e 88 palestrantes dos últimos 5 congressos da SBCP, que foram comparados com 102 médicos sócios não palestrantes da SBCP. Os palestrantes publicaram mais trabalhos científicos que os não palestrantes (p&lt;0,0009), e os conferencistas produziram estatisticamente mais publicações (p&lt;0,0009). Maior visibilidade foi observada em São Paulo, Rio de Janeiro e Minas Gerais (71,8%, 6,5% e 6,5% dos palestrantes respectivamente), e maior atividade científica foi observada entre 20 e 40 anos de atividade profissional. A grande maioria das publicações foi em revistas nacionais, especialmente na revista da SBCP (aproximadamente 45%). CONCLUSÃO: A exposição do médico como convidado nos congressos da SBCP e o volume de produção científica estão correlacionados.

CORE VALUES AND EVALUATION PROCESSES ASSOCIATED WITH ACADEMIC TENURE1

This study replicated the 1989 national study by the Carnegie Foundation for the Advancement of Teaching in which the relative importance of teaching, scholarship, and service in tenure decisions was examined. The deans of the National League for Nursing accredited programs (N = 187) and deans of Allied Health programs belonging to the Association of Schools of Allied Health Professions (N = 75) were surveyed to identify the core values and evaluation processes used in granting tenure. Most deans who participated stated it is difficult to achieve tenure in the absence of publication in refereed journals. The number of journal publications, reputation of the journal, presentation at scientific conferences, and published reviews of the scholars' books are considered critical in granting tenure. Furthermore, advising students, service in the department and university, and course evaluation by students were considered critical to granting tenure. Overall, the opinions of the nursing and allied health deans on the core values and the evaluation processes used in tenure decisions were similar, but divergent from those of the “health sciences” faculty members in the Carnegie Foundation study. These findings suggest a shift in the criteria used in tenure decisions today.

International Collaboration of Clinical Medicine Research in Taiwan, 1990-2004: A Bibliometric Analysis

The number of publications in journals indexed in the Institute for Scientific Information (ISI) database of the Thomson Corporation is generally used to assess the research performance of individuals, institutions and countries in scientific fields. The aim of this study was to analyze the trends in Taiwan's ISI publications in clinical medicine from 1990 to 2004. Special attention was paid to internationally collaborated works that were identified based on the countries of co-authors' affiliations. The bibliographic records of articles with an author's affiliation in Taiwan were downloaded from the Web of Science on the Internet. The analysis was then limited to the journals of clinical medicine defined as such in the ISI Essential Science Indicators. International collaboration was deemed to exist in an article if any co-author's affiliation was located outside Taiwan. The impact factors in the 2004 Journal Citation Reports Science Edition were arbitrarily adopted to estimate the quality of articles. Taiwan's ISI publications in clinical medicine increased from 315 articles in 1990 to 2,636 in 2004. Only 7.4% (n=1,494) of the 20,207 articles published during the study period were published in journals with an impact factor equal to or greater than 5. The share of articles with international collaboration was 13.6% (n=2,752) on average. Taiwan's researchers collaborated with colleagues in 76 countries. The USA, as the most important collaborating partner of Taiwan's clinical medicine researchers, had contributed to 69.9% of articles with international collaboration. Generally, articles with international collaboration were published in journals with higher impact factors or had more citations than those without international collaboration. The number of articles published in each year, in each of selected subject categories and from each of selected domestic institutions did not correlate with the percentage of articles with international collaboration, respectively. Taiwan has achieved a significant increase in the number of ISI publications in clinical medicine. Yet there exists opportunity for improvement in international collaboration.

The delicate topic of the impact factor

In the early 1960s, Irving H. Sher and Eugene Garfield created the journal impact factor (IF) to help select journals for the new Science Citation Index (SCI). They quickly recognised that small journals which specialise in certain topics may not be selected if dependent solely on total publications or citation counts. A simple method was then required for journals, regardless of size or citation frequency—the impact factor [1]. A journal’s IF is based on two elements: the numerator, which is the number of citations in the current year to any items published in a journal in the previous 2 years, and the denominator, which is the number of substantive articles (source items) published in the same 2 years. Experience has shown that in each specialty the best journals are those in which it is most difficult to have an article accepted, and these are the journals that have a high IF. The use of the impact factor in research evaluation Particularly in Germany, as in Austria and in Japan, the IF has developed significant influence beyond its original goal. In these countries, research assessment rests too heavily on the inflated status of the impact factor. In its original sense, the IF represents a comparative measure of the quality of a journal. The IF simply reflects the ability of journals and editors to attract the best papers available [2]. Hence, the IF stands for the quality of the journal and not for the quality of the individual paper. In practical use in Germany, however, the IF of the journal is taken as a measure for the individual paper. Furthermore, the journal’s IF is attributed to each author of that specific article, irrespective of the number of authors and the contribution he or she made to this article. The individual citation rate of an author or article is totally neglected in this system. Despite evident limitations, the IF is very influential. Although even Thomson Scientific acknowledges that the impact factor has grown beyond its control and is being used in many inappropriate ways, the impact factors of journals have been used to decide whether or not authors get promoted, are given tenure or are offered a position in a department, or are awarded a grant. In some countries, especially in Europe and Japan, government funding of entire institutions is dependent on the number of publications in journals with high impact factors. Finally, the sum of IF points of a person is considered as a measure of his individual research quality. This has obvious appeal for an academic administrator who knows neither the subject nor the journals [3]. Seglen points out that about 15% of the articles in a typical journal account for half of the citations gained by that publication. This means that an average paper in a journal with a high impact factor may not, in fact, be cited much more frequently than the average paper in a lower-ranking journal. Therefore the IF of the source journal should not be used as a substitute measure of the citation impact of individual articles in the journal [4].

Publikationsindikatoren und die Stabilität wirtschaftswissenschaftlicher Zeitschriftenrankings

The output of single researchers or departments can be measured by the number of publications in journals. Due to heterogenity in the quality of journals the publications must be weighted. The quality of a journal can be determined on the basis of citation analysis, by reputation or by the quality of the review process. We present rankings of German business and economics journals based on citation analysis for the last three decades of the twentieth century respectively. If used for decision making in universities journal rankings must be robust in respect to method and over time. Using correlation analysis we find that rankings of German business journals are very robust in respect to both method and time. Rankings of German economics journals are not as robust as business journals but still show positive correlations over time and with different methods.

Sociology research at liberal arts colleges

þis article examines the research activity in sociology by faculty at liberal arts col-leges. We used Sociological Abstracts to compile a list of journal articles published from 1960 to 1999 for which the first author's affiliation was among the 161 schools classified as liberal arts colleges by the Carnegie Foundation. We rank the colleges by the number of journal publications over the whole time period as well as a subset of the last ten years, and provide information on which journals are the most frequent outlets for liberal arts faculty. Finally, we provide some evidence that this research output is linked to teaching effectiveness. During the past fifty years there has been an amazing development of the colleges and universities of this country. They have grown in numbers, in size of faculties, in enrollments of students, in scope of work....It has seemed worth while to attempt to secure a rating of the graduate schools in the different lines of study based on the opinions of a considerable group of college professors....Such a rating also seems proper and desirable in printed form, so that any one interested can turn to it readily for a rough estimate of the work in a given field.
