The dissemination of the practice of collaborative authorship (coauthorship) in Brazil and in the international scientific community has been accompanied by an increasing occurrence of frauds, manipulations and other deviations in the assignment of responsibility for a scientific paper. This article discusses the criteria for authorship attribution, the reasons for the growing indices of coauthorship and the challenges to determine authorship in electronic journals. Through literature review and case study (bibliographic search in scientific database), it shows ways to avoid that "misbehaviors" related to the authorship attribution affect the credibility of science.

"What is Authorship, and What Should it Be? A Survey of Prominent Guidelines for Determining Authorship in Scientific Publications"

Full Text Available Before the mid 20th century most scientific writing was solely authored (Claxton, 2005; Greene, 2007 and thus it is only relatively recently, as science has grown more complex, that the ethical and procedural issues around authorship have arisen. Fields as diverse as medicine (International Committee of Medical Journal Editors, 2008, mathematics (e.g., American Statistical Association, 1999, the physical sciences (e.g., American Chemical Society, 2006, and the social sciences (e.g., American Psychological Association, 2002 have, in recent years, wrestled with what constitutes authorship and how to eliminate problematic practices such as honorary authorship and ghost authorship (e.g., Anonymous, 2004; Claxton, 2005; Manton & English, 2008. As authorship is the coin of the realm in academia (Louis, Holdsworth, Anderson, & Campbell, 2008, it is an ethical issue of singular importance. The goal of this paper is to review prominent and diverse guidelines concerning scientific authorship and to attempt to synthesize existing guidelines into recommendations that represent ethical practices for ensuring credit where (and only where credit is due.

Full Text Available This article is a narrative review about how appropriate authorship can be achieved, a brief mention about various scientific misconducts, the reason and consequences of such misconducts and finally, the policies to be adopted by the aspiring authors to avert these problems. The literature search was performed in the Google and PubMed using ′scientific misconduct′, ′honorary/ghost authorship′, ′publish-or-perish′, ′plagiarism′ and other related key words and phrases. More than 300 free full-text articles published from 1990 to 2015 were retrieved and studied. Many consensus views have been presented regarding what constitutes authorship, the authorship order and different scientific misconducts. The conflicts about authorship issues related to publication of dissertation, the area of the grey zone have been discussed. Suggestions from different authorities about improving the existing inappropriate authorship issues have been included.

Multiple Authorship in Scientific Manuscripts: Ethical Challenges, Ghost and Guest/Gift Authorship, and the Cultural/Disciplinary Perspective.

Multiple authorship is the universal solution to multi-tasking in the sciences. Without a team, each with their own set of expertise, and each involved mostly in complementary ways, a research project will likely not advance quickly, or effectively. Consequently, there is a risk that research goals will not be met within a desired timeframe. Research teams that strictly scrutinize their modus operandi select and include a set of authors that have participated substantially in the physical undertaking of the research, in its planning, or who have contributed intellectually to the ideas or the development of the manuscript. Authorship is not an issue that is taken lightly, and save for dishonest authors, it is an issue that is decided collectively by the authors, usually in sync with codes of conduct established by their research institutes or national ministries of education. Science, technology and medicine (STM) publishers have, through independent, or sometimes coordinated efforts, also established their own sets of guidelines regarding what constitutes valid authorship. However, these are, for the greater part, merely guidelines. A previous and recent analysis of authorship definitions indicates that the definitions in place regarding authorship and its validity by many leading STM publishers is neither uniform, nor standard, despite several of them claiming to follow the guidelines as set forward by the International Committee of Medical Journal Editors or ICMJE. This disparity extends itself to ghost and guest authorship, two key authorship-related issues that are examined in this paper to assess the extent of discrepancies among the same set of STM publishers and what possible influence they might have on publishing ethics.

The purpose of this study was to examine gender disparities in prosthodontics by reviewing the trend of female authorship in prosthodontic journals and exploring the role of female leadership in prosthodontic organizations and Advanced Education in Prosthodontic (AEP) programs. Three journals representing the prosthodontic specialty were selected to analyze the percentage of female dentist first and last (senior) authors for the years 1995, 2000, 2005, and 2008. Article inclusion criteria were restricted to the first or last authors who held at least a DMD/DDS/BDS degree and were from U.S. institutions. Data on female leadership in prosthodontic organizations and advanced education programs were collected, and the trends were studied. Descriptive statistics were used to analyze the data. A linear regression analysis was performed to investigate the proportion of female authorship compared to male in the dental literature. A Fisher's Exact Test was performed to contrast differences of female first and last authorship in the selected journals between years 1995 and 2008. Overall, there was no statistically significant linear increase in the proportion of either first or last female authorship compared to male authorship over time. With respect to each journal, the linear regression analysis showed that the increase of first female authorship was statistically significant (p= 0.016) compared to male authorship only in the Journal of Prosthetic Dentistry. The percentage of female presidents of prosthodontic organizations has been very limited. A similar trend was also observed in AEP program director positions. Over the past 13 years, female dentists' participation in prosthodontics literature authorship has not increased significantly in the United States. Furthermore, female involvement in prosthodontics leadership has been limited over the past decades. © 2010 by The American College of Prosthodontists.

The aim of this study was to retrospectively identify trends in the representation of female authorship in prominent general radiology journals over the past 2 decades. A comprehensive search was conducted for all articles published in 1993, 2003, and 2013 in Radiology, the American Journal of Roentgenology (AJR), European Radiology, and Investigative Radiology. The genders of the first and last authors were collected. Chi-square tests were used for statistical analysis, and P values authorship, 24.7% of first authors, and 15.2% of senior authors. The average overall female first and senior authorship grew from 19.7% to 32.1% and from 13.6% to 19.1%, respectively from 1993 to 2013. Female first authorship grew over the past 2 decades in the journals reviewed, with significant growth in AJR and Radiology (P authorship in the individual journals grew from 16.4%-29.1% in 1993, to 29.1%-34.8% in 2013. Female senior authorship also demonstrated growth in the past 2 decades, growing from 4.3%-17.5% in 1993 to 15.5%-23.2% in 2013. There was significant growth in senior female authorship in Radiology (from 12.1% to 19.2%, P = .004) and European Radiology (from 4.3% to 15.5%, P = .0433). Female senior authorship remained significantly lower than first authorship over the past 2 decades (P = .002, P authorship in radiology literature is proportional to their growth in the specialty, they continue to remain a minority, especially in senior authorship, and demonstrate similar participation to other medical specialties.

New developments in publishing related to authorship.

Science.gov (United States)

Donev, Doncho

2014-01-01

To present the inappropriate types of authorship and practice, and the most recent developments related to basic principles and criteria to a fair system for allocating authorship in scientific publications. An analysis of relevant materials and documents, sources from the internet and published literature and personal experience and observations of the author. Working in multidisciplinary teams is a common feature of modern research processes. The most sensitive question is how to decide on who to acknowledge as author of a multi-authored publication. The pertinence of this question is growing with the increasing importance of individual scientists' publication records for professional status and career. However, discussions about authorship allocation might lead to serious conflicts and disputes among coworkers which could even endanger cooperation and successful completion of a research project. It seems that discussion and education about ethical standards and practical guidelines for fairly allocating authorship are insufficient and the question of ethical practices related to authorship in multi-authored publications remains generally unresolved. It is necessary to work for raising awareness about the importance and need for education about principles of scientific communication and fair allocation of authorship, ethics of research and publication of results. The use of various forms of education in the scientific community, especially young researchers and students, in order to create an ethical environment, is one of the most effective ways to prevent the emergence of scientific and publication dishonesty and fraud, including pathology of authorship.

Ongoing ethical issues concerning authorship in biomedical journals: an integrative review.

Kornhaber, Rachel Anne; McLean, Loyola M; Baber, Rodney J

2015-01-01

Health professionals publishing within the field of health sciences continue to experience issues concerning appropriate authorship, which have clinical, ethical, and academic implications. This integrative review sought to explore the key issues concerning authorship from a bioethical standpoint, aiming to explore the key features of the authorship debate. Studies were identified through an electronic search, using the PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Scopus databases of peer-reviewed research, published between 2009 and 2014, limited to English language research, with search terms developed to reflect the current issues of authorship. From among the 279 papers identified, 20 research papers met the inclusion criteria. Findings were compiled and then arranged to identify themes and relationships. The review incorporated a wide range of authorship issues encompassing equal-credited authors, honorary (guest/gift) and ghost authorship, perception/experiences of authorship, and guidelines/policies. This review suggests that the International Committee of Medical Journal Editors' (ICMJE) recommended guidelines for authorship are not reflected in current authorship practices within the domain of health sciences in both low-and high-impact-factor journals. This devaluing of the true importance of authorship has the potential to affect the validity of authorship, diminish the real contributions of the true authors, and negatively affect patient care.

2013-11-01

Full Text Available In this paper we present a model for email authorship identification (EAI by employing a Cluster-based Classification (CCM technique. Traditionally, stylometric features have been successfully employed in various authorship analysis tasks; we extend the traditional feature set to include some more interesting and effective features for email authorship identification (e.g., the last punctuation mark used in an email, the tendency of an author to use capitalization at the start of an email, or the punctuation after a greeting or farewell. We also included Info Gain feature selection based content features. It is observed that the use of such features in the authorship identification process has a positive impact on the accuracy of the authorship identification task. We performed experiments to justify our arguments and compared the results with other base line models. Experimental results reveal that the proposed CCM-based email authorship identification model, along with the proposed feature set, outperforms the state-of-the-art support vector machine (SVM-based models, as well as the models proposed by Iqbal et al. (2010, 2013 [1,2]. The proposed model attains an accuracy rate of 94% for 10 authors, 89% for 25 authors, and 81% for 50 authors, respectively on Enron dataset, while 89.5% accuracy has been achieved on authors’ constructed real email dataset. The results on Enron dataset have been achieved on quite a large number of authors as compared to the models proposed by Iqbal et al. [1,2].

Literature review. To examine changes in authorship characteristics for Spine publications from the year 2000-2015. Scientific publications are considered an indication of academic achievement for physicians. Recently, authorship trends have been investigated, however, limited information is available on this topic within spine-specific literature. Original research articles published in Spine in the years 2000, 2005, 2010, and 2015 were evaluated. Authorship characteristics were collected for each article, including the number of authors and institutions per publication, first and last author gender, publication origin, and highest degree held by the first and last author. Trends over time were analyzed using numeric and visual descriptive analyses including percentages, means, standard deviations, and graphs. An average of 506 articles per year were published in Spine during the years 2000, 2005, 2010, and 2015. The number of articles written by ≥ 10 authors increased during this time (0.9% to 14.4%). There was a substantial increase in the number of multiple institutional affiliations (33.6% to 68.7%) and articles originating from outside North America (47.6% to 55.7%) from 2000 to 2015. The percentage of first authors with bachelor's degrees was higher in 2015 (6.6%) as compared to 2000 (1.4%), and more last authors were identified as MD/PhDs in 2015 (19.2%) than in 2000 (10.0%). Similar female representation was noted for first and last authorship for all years evaluated. The results of this study demonstrate increases in authors per article published in Spine from 2000 to 2015. Additionally, first authors were more likely to hold bachelor's degrees over time. This may be attributed to increasing competition in spine-related fields, necessitating earlier research exposure to aid in academic achievement. Interestingly, the percentage of female authorship has not changed significantly over time, in contrast with much of the previous literature. 2.

Authorship in Radiation Oncology: Proliferation Trends Over 30 Years

Energy Technology Data Exchange (ETDEWEB)

Ojerholm, Eric, E-mail: eric.ojerholm@uphs.upenn.edu; Swisher-McClure, Samuel

2015-11-15

Purpose: To investigate authorship trends in the radiation oncology literature. Methods and Materials: We examined the authorship credits of “original research articles” within 2 popular radiation oncology journals–International Journal of Radiation Oncology, Biology, Physics and Radiotherapy and Oncology–in 1984, 1994, 2004, and 2014. We compared the number of authors per publication during these 4 time periods using simple linear regression as a test for trend. We investigated additional author characteristics in a subset of articles. Results: A total of 2005 articles were eligible. The mean number of authors per publication rose from 4.3 in 1984 to 9.1 in 2014 (P<.001). On subset analysis of 400 articles, there was an increase in the percentage of multidisciplinary bylines (from 52% to 72%), multi-institutional bylines (from 20% to 53%), and publications with a trainee first author (from 16% to 56%) during the study period. Conclusions: The mean number of authors per publication has more than doubled over the last 30 years in the radiation oncology literature. Possible explanations include increasingly complex and collaborative research as well as honorary authorship. Explicit documentation of author contributions could help ensure that scientific work is credited according to accepted standards.

Gender equality in academic research on epilepsy-a study on scientific authorships.

The study aims to elucidate the state of gender equality in epilepsy research, analyzing the representation of female authorships from 2008 to 2016. Gendermetrics aided in analyzing 106,282 authorships from 22,180 epilepsy-related original research articles. The key methodology was the combined analysis of the relative frequency and the odds ratio of female authorships. The Prestige Index measures the distribution of prestigious authorships between the two genders. The following were held by women: 39.6% of all authorships and 44.1% of the first, 41.0% of the co-, and 29.0% of the last authorships. Female authors have an odds ratio of 1.25 (95% CI 1.21-1.29) for first, 1.17 (CI 1.14-1.20) for co-, and 0.57 (CI 0.55-0.59) for last authorships. The female authorship ratios showed substantial growth in recent years, with an annual growth rate of 1.7% overall, with 2.4% for first, 1.4% for co-, and 1.9% for last authorships. Women publish fewer articles compared to men (43.8% female authors hold 39.6% of the authorships). Women are also less likely to secure prestigious authorships in articles with many authors that attract the highest citation rates. Multi-author articles with male key authors are cited slightly more frequently than articles with female key authors. Distinct differences at the country level were revealed. The prognosis for the next decade forecasts significantly increasing female odds for first authorships and only slightly higher female odds for last authorships. A female authorship ratio of 49.2% is predicted for the year 2026. The integration of women in the scientific field of epilepsy is advanced. However, a dichotomy is present: Although the current system promotes early career steps, there is an apparent lack of female research leaders. This structural imbalance is expected to grow in the next decade due to the consistently high increase of female early career researchers.

The frequency of conflicts about authorship of publications has increased along with the increase in the number of people involved in scientific work. Some of the factors that strongly influence the generation of conflicts and malpractices in authorship definition of scientific publications are the pressure of academia, economic incentives from the pharmaceutical industry in the field of biomedicine and authors’ wishes and expectations of recognition, among other factors. The article analyzes this problem, increasingly common in the field of medicine and related areas. Special attention is devoted to the prevailing laws in our country and international guidelines related to intellectual property and authorship of scientific publications, respectively. However, the ethical commitment, intellectual honesty and truthfulness of each of the authors about what is reported seems to be the decisive factor for the solution to these authorship conflicts.

Honorary and ghost authorship in nursing publications.

The purposes of this study were to (a) assess the prevalence of articles with honorary authors and ghost authors in 10 leading peer-reviewed nursing journals between 2010 to 2012; (b) compare the results to prevalence reported by authors of articles published in high-impact medical journals; and (c) assess the experiences of editors in the International Academy of Nursing Editors with honorary and guest authorship. Corresponding authors of articles published in 10 nursing journals between 2010 and 2012 were invited to complete an online survey about the contributions of coauthors to see if the International Committee of Medical Journal Editors () criteria for authorship were met. Additionally, members of the International Academy of Nursing Editors were invited to complete an online survey about their experiences in identifying honorary or ghost authors in articles submitted for publication. The prevalence of articles published in 10 nursing journals with honorary authors was 42%, and the prevalence of ghost authorship was 27.6%. This is a greater prevalence than what has been reported among medical journals. Qualitative data yielded five themes: lack of awareness around the rules for authorship; acknowledged need for debate, discussion, and promotion of ethical practice; knowingly tolerating, and sometimes deliberately promoting, transgressions in practice; power relations and expectations; and avoiding scrutiny. Among the 60 respondents to the editor survey, 22 (36.7%) reported identifying honorary authors and 13 (21.7%) reported ghost authors among papers submitted to their publications. Inappropriate authorship is a significant problem among scholarly nursing publications. If nursing scholarship is to maintain integrity and be considered trustworthy, and if publications are to be a factor in professional advancement, editors, nursing leaders, and faculty need to disseminate and adhere to ethical authorship practices. © 2014 Sigma Theta Tau International.

Human performance in orbit is currently limited by several factors beyond the intrinsic awkwardness of motor control in weightlessness. Cognitive functioning can be affected by such factors as cumulative sleep loss, stress and the psychological effects of long-duration small-group isolation. When an astronaut operates a scientific experiment, the performance decrement associated with such factors can lead to lost or poor quality data and even the total loss of a scientific objective, at great cost to the sponsors and to the dismay of the Principal Investigator. In long-duration flights, as anticipated on the International Space Station and on any planetary exploration, the experimental model is further complicated by long delays between training and experiment, and the large number of experiments each crew member must perform. Although no documented studies have been published on the subject, astronauts report that an unusually large number of simple errors are made in space. Whether a result of the effects of microgravity, accumulated fatigue, stress or other factors, this pattern of increased error supports the need for a computerized decision-making aid for astronauts performing experiments. Artificial intelligence and expert systems might serve as powerful tools for assisting experiments in space. Those conducting space experiments typically need assistance exactly when the planned checklist does not apply. Expert systems, which use bits of human knowledge and human methods to respond appropriately to unusual situations, have a flexibility that is highly desirable in circumstances where an invariably predictable course of action/response does not exist. Frequently the human expert on the ground is unavailable, lacking the latest information, or not consulted by the astronaut conducting the experiment. In response to these issues, we have developed "Principal Investigator-in-a-Box," or [PI], to capture the reasoning process of the real expert, the Principal

To evaluate the disparity in authorship based on gender and nationality of institutional affiliation among journals from developed and developing countries. Original articles from two neuroscience journals, with a 5 year impact factor >15 (Neuron and Nature Neuroscience) and from two neurology journals from a developing country (Neurology India and Annals of Indian Academy of Neurology) were categorized by gender and institutional affiliation of first and senior authors. Articles were further divided by the type of research (basic/translational/clinical), study/target population (adult/pediatrics/both) and field of neurology. Data was collected for the years 2002 and 2012. There are large disparities in authorship by women and from developing countries in high impact factor neuroscience journals. However, there was a non-statistical rise in female first and senior authorship over a 10 year period. Additionally there was a significant increase in first authorship from institutions based in developing countries in the two neuroscience journals examined (P < 0.05). In the two neurology journals based in India there was a significant increase in the number of articles published by international investigators between 2002 and 2012 (P < 0.05). Over the last decade, there has been a non-statistical increase in proportion of female first and senior authors, and a significant increase in authors from developing countries in high impact factor neuroscience journals. However they continue to constitute a minority. The disparity in authorship based on gender also exists in neurology journals based in a developing country (India).

Automated authorship attribution using advanced signal classification techniques.

Directory of Open Access Journals (Sweden)

Maryam Ebrahimpour

Full Text Available In this paper, we develop two automated authorship attribution schemes, one based on Multiple Discriminant Analysis (MDA and the other based on a Support Vector Machine (SVM. The classification features we exploit are based on word frequencies in the text. We adopt an approach of preprocessing each text by stripping it of all characters except a-z and space. This is in order to increase the portability of the software to different types of texts. We test the methodology on a corpus of undisputed English texts, and use leave-one-out cross validation to demonstrate classification accuracies in excess of 90%. We further test our methods on the Federalist Papers, which have a partly disputed authorship and a fair degree of scholarly consensus. And finally, we apply our methodology to the question of the authorship of the Letter to the Hebrews by comparing it against a number of original Greek texts of known authorship. These tests identify where some of the limitations lie, motivating a number of open questions for future work. An open source implementation of our methodology is freely available for use at https://github.com/matthewberryman/author-detection.

To develop a method for investigating co-authorship patterns and author team characteristics associated with the publications in high-impact journals through the integration of public MEDLINE data and institutional scientific profile data. For all current researchers at Columbia University Medical Center, we extracted their publications from MEDLINE authored between years 2007 and 2011 and associated journal impact factors, along with author academic ranks and departmental affiliations obtained from Columbia University Scientific Profiles (CUSP). Chi-square tests were performed on co-authorship patterns, with Bonferroni correction for multiple comparisons, to identify team composition characteristics associated with publication impact factors. We also developed co-authorship networks for the 25 most prolific departments between years 2002 and 2011 and counted the internal and external authors, inter-connectivity, and centrality of each department. Papers with at least one author from a basic science department are significantly more likely to appear in high-impact journals than papers authored by those from clinical departments alone. Inclusion of at least one professor on the author list is strongly associated with publication in high-impact journals, as is inclusion of at least one research scientist. Departmental and disciplinary differences in the ratios of within- to outside-department collaboration and overall network cohesion are also observed. Enrichment of co-authorship patterns with author scientific profiles helps uncover associations between author team characteristics and appearance in high-impact journals. These results may offer implications for mentoring junior biomedical researchers to publish on high-impact journals, as well as for evaluating academic progress across disciplines in modern academic medical centers.

To evaluate trends in the prevalence of women authors in ophthalmology in recent years. Cohort study. Authors listed in publications of 6 leading ophthalmology journals between January 2002 and December 2014. Using the PubMed search engine, we conducted an observational study of trends in gender distribution of all authors in 6 leading ophthalmology journals between January 2002 and December 2014. In multiauthored articles, the first listed author often is the lead investigator and the last author is the senior author. Therefore, the full names and positions (first, middle, or last) of all authors in every article were collected. A Google-based name identifier was used to assign the gender of authors. Proportion of women authors throughout the study period in all journals, general ophthalmology versus subspecialty journals, and basic science versus clinical research journals. Furthermore, we assessed the proportion of women in different authorship positions (first, middle, and last). A total of 102 254 authors from 23 026 published articles were analyzed. There was a significant rise over time in the percentage of women authors, with a steeper slope for first authors than for last authors (P<0.001), although in 2014, women authors were less than the 50% mark in all categories of authorship. The rise in the percentage of women authors was similar in basic and clinical research, but was steeper for first authorship than for last authorship (P<0.001). In all 3 authorship positions (first, middle, or last), women's contributions consistently were higher in basic research publications. The rise in the percentage of women authors was significantly steeper for general journals than for subspecialty journals (P<0.001). There was no significant rise for last authorship in subspecialty journals. In all 3 authorship positions, the proportion of women was consistently higher in general ophthalmology journals than for subspecialty journals. Despite an overall increase in

We evaluated the authorship count of all original research and review articles published in prominent Urology journals to trend patterns in authorship over the last decade. Secondarily, we evaluated bibliometric assessments and sought to understand whether authorship count was associated with citation rate and each article's field-normalized measure of impact. Information on authorship count, date of publication, study type, journal of publication, citation rate, and relative citation ratio (RCR) was collected for all original research and review articles published in European Urology, Journal of Urology, Urology , and British Journal of Urology International between 2006 and 2016. We examined trends in authorship count over the past decade, as well as between journals and article types. 21,336 articles were analyzed, of which 19,527 (91.5%) were original research and 1,809 (8.5%) were review articles. Overall, number of authors increased 46.1% from 2006 to 2016. Authorship counts in original research articles increased by an average of 2.45 per manuscript (43.3% increase) over the decade analyzed. More dramatically, authorship counts in review articles increased by an average of 3.14 per manuscript (92.6% increase). Articles with higher authorship counts were associated with more citations and greater RCR (r=0.13, p<0.001). There is a global trend towards more authors per article in urology publications-in both original research publications and review articles, and across each of the individual journals evaluated. An increase in author count has also been associated with increased citations and measures of article impact.

Full Text Available Studies on female co-authorship in the scientific production of various areas of knowledge are frequent in international scientific literature. However, this object of study has been little explored by Brazilian research in the field of Information Science. This article presents a contribution to this area by presenting the results of a research that investigated female co-authorship and the participation of women in the editorial staff of Brazilian scientific journals in the area of surgery published between 2010 and 2014. The corpus investigated consisted of 920 articles published in four scientific journals: Acta Cirúrgica Brasileira (ACB, Arquivos Brasileiros de Cirurgia Digestiva (ABCD, Revista Brasileira de Cirurgia Cardiovascular (RBCCV and Revista do Colégio Brasileiro de Cirurgiões (RCBC. The bibliometric analysis is the methodological approach adopted and sample universe were 920 articles written by 5649 co-authors. Men appear as coauthors in 63.5% (n=585 of articles, while women show up as coauthors in 23.8% (219 of all articles. By investigating the gender of coauthorship in original and review articles, the results showed that women's participation is lower than men in both types and in all four journals. Observing the participation of women in editorial boards of the journals, the results revealed that in only one journal (ABCD the female presence is unique and exclusive. The study showed that gender inequality persists in terms of authorship, co-authorships, types of articles, and also on the editorial board, scientific committee and board of reviewers.

Full Text Available This paper aims at analyzing a number of consequences of the concept of authorship in the contemporary debate. Therefore, two objects, representing current tendencies, where chosen, both marked by the dynamics of cyberculture: Facebook and fandom. The first, a social network widely used in Brazil, does not require introductions. The latter is less known by general public, because it refers to a space used by fans to discuss the works they love. Through the analysis of these two virtual spaces, this paper is going to show how the authorship is called into question nowadays. It is going to describe the attempts of authors hedging their symbolic space and the readers’ strategies to conquer the authorship field.

Measuring co-authorship and networking-adjusted scientific impact.

Directory of Open Access Journals (Sweden)

John P A Ioannidis

Full Text Available Appraisal of the scientific impact of researchers, teams and institutions with productivity and citation metrics has major repercussions. Funding and promotion of individuals and survival of teams and institutions depend on publications and citations. In this competitive environment, the number of authors per paper is increasing and apparently some co-authors don't satisfy authorship criteria. Listing of individual contributions is still sporadic and also open to manipulation. Metrics are needed to measure the networking intensity for a single scientist or group of scientists accounting for patterns of co-authorship. Here, I define I(1 for a single scientist as the number of authors who appear in at least I(1 papers of the specific scientist. For a group of scientists or institution, I(n is defined as the number of authors who appear in at least I(n papers that bear the affiliation of the group or institution. I(1 depends on the number of papers authored N(p. The power exponent R of the relationship between I(1 and N(p categorizes scientists as solitary (R>2.5, nuclear (R = 2.25-2.5, networked (R = 2-2.25, extensively networked (R = 1.75-2 or collaborators (R<1.75. R may be used to adjust for co-authorship networking the citation impact of a scientist. I(n similarly provides a simple measure of the effective networking size to adjust the citation impact of groups or institutions. Empirical data are provided for single scientists and institutions for the proposed metrics. Cautious adoption of adjustments for co-authorship and networking in scientific appraisals may offer incentives for more accountable co-authorship behaviour in published articles.

Gendered Authorship and Demographic Research: An Analysis of 50 Years of Demography.

Science.gov (United States)

Krapf, Sandra; Kreyenfeld, Michaela; Wolf, Katharina

2016-08-01

Demography, the official journal of the Population Association of America, has been given the highest rating among demographic journals by the Social Sciences Citation Index (SSCI). Our aim here is to investigate the development of research subfields and female authorship in Demography over the last 50 years. We find that female authorship in Demography has risen considerably since the 1980s and that currently a woman is about as likely as a man to be the sole or the first author of a paper published in the journal. However, we find some differences by subfield. Women seem to be overrepresented in the "family and household" research subfield but underrepresented in the "mortality and health" and "data and methods" categories.

Believing and perceiving: authorship belief modulates sensory attenuation.

Directory of Open Access Journals (Sweden)

Andrea Desantis

Full Text Available Sensory attenuation refers to the observation that self-generated stimuli are attenuated, both in terms of their phenomenology and their cortical response compared to the same stimuli when generated externally. Accordingly, it has been assumed that sensory attenuation might help individuals to determine whether a sensory event was caused by themselves or not. In the present study, we investigated whether this dependency is reciprocal, namely whether sensory attenuation is modulated by prior beliefs of authorship. Participants had to judge the loudness of auditory effects that they believed were either self-generated or triggered by another person. However, in reality, the sounds were always triggered by the participants' actions. Participants perceived the tones' loudness attenuated when they believed that the sounds were self-generated compared to when they believed that they were generated by another person. Sensory attenuation is considered to contribute to the emergence of people's belief of authorship. Our results suggest that sensory attenuation is also a consequence of prior belief about the causal link between an action and a sensory change in the environment.

Piper, Crystal L; Scheel, John R; Lee, Christoph I; Forman, Howard P

2016-01-01

The purpose of this study was to describe trends over time in female authorship in the radiology literature and to investigate the tendency of female first authors to publish with female senior authors. Data on the gender of academic physician authors based in the United States for all major articles published in three general radiology journals--Radiology, AJR, and Academic Radiology--were collected and analyzed for the years 1978, 1988, 1998, 2008, and 2013. Multivariate logistic regression was used to identify significant trends over time, and a chi-square test of independence was performed to determine significant relations between the genders of first and senior authors. The gender of 4182 of 4217 (99.17%) authors with MD degrees was determined. The proportion of original research articles published by women as first authors increased from 8.33% in 1978 to 32.35% in 2013 (p < 0.001). The proportion of original research articles with women as senior authors increased from 6.75% in 1978 to 21.90% in 2013 (p < 0.001). Female first and senior authorship increased significantly over time (first author, p < 0.001; senior author, p < 0.001). There was a statistically significant relation between the genders of first and senior authors of original research articles and guest editorials (p < 0.001). Over 35 years, there was a statistically significant upward linear trend of female physician participation in authorship of academic radiology literature. Female first authors were more likely to publish with female senior authors.

Eisenberg, Ronald L; Ngo, Long; Boiselle, Philip M; Bankier, Alexander A

2011-05-01

To quantify the frequency of perceived honorary authorship in radiologic journals and to identify specific factors that increase its prevalence. This study qualified for exempt status by the institutional review board. An electronic survey was sent to first authors of all original research articles published in Radiology and European Radiology over 3 years. Questions included guidelines used for determining authorship, contributions of coauthors, the perception of honorary authorship, and demographic information. Univariable analysis of sample proportions was performed by using χ(2) tests. Multivariable logistic regression models were used to assess the independent factors that were associated with the probability of perceiving honorary authorship. Of the 392 (29.3%) of 1338 first authors who responded to the survey, 102 (26.0%) perceived that one or more coauthors did not make sufficient contributions to merit being included as an author. Of the 392 respondents, 231 (58.9%) stated that one or more coauthors performed only "nonauthor" tasks according to International Committee of Medical Journal Editors criteria. Factors associated with an increased first-author perception of honorary authorship included lower academic rank (adjusted odds ratio [OR]: 2.89; 95% confidence interval [CI]: 1.66, 5.06), as well as working in an environment in which the section or department head was automatically listed as an author (adjusted OR: 3.80; 95% CI: 2.13, 6.79). The percentage of honorary authorship was significantly higher (P = .019) among respondents who did not follow journal requirements for authorship. The rate of perceived honorary authorship (overall, 26.0%) was substantially more frequent among respondents of lower academic rank and in those working in an environment in which their section or department head was automatically listed as an author. http://radiology.rsna.org/lookup/suppl/doi:10.1148/radiol.11101500/-/DC1.

2016-09-01

Full Text Available http://dx.doi.org/10.5007/2175-8026.2016v69n3p63 The theme of this article is 'Education for authorship in university'; it is organized to answer the following question: What challenges does the academic sphere face as regards education for authorship today? In order to answer that question, the text spouses a theoretical-epistemological affiliation of a historical-cultural basis, employing a comprehensive approach in the generation and analysis of data, which derive from a number of studies consolidated or in phase of consolidation in the Research Group 'Writing Culture and Schooling' of Universidade Federal de Santa Catarina. In response to the research question, it is argued that there are, among many others, three major challenges of substantive relevance in education for authorship: (i appropriation of knowledge tensioned by relativistic fundamentals in the school sphere; (ii academic expectations with condescending attitudes; and (iii selective attention as opposed to auscultation. It is argued that an education for authorship in the academic sphere involves the expansion of individuals’ cultural repertoire throughout their education so as they consolidate a condition of autonomy in opposition to heteronomy.

Popular Authorship Reconfigured: Stephen King’s Authorial Personae from Print to Digital Environments

Directory of Open Access Journals (Sweden)

Despoina Feleki

2014-04-01

Full Text Available The convergence of literary practices with computer information technologies (ICTs has immensely affected writing processes and theories of authorship. This paper aims to foreground contemporary sociocultural conditions which have reconfigured authorship in relation to the materiality of the product through the example of Stephen King’s writing and marketing choices. An investigation of selected printed and digital works, including Misery, Lisey’s Story, Duma’s Key, and UR, showcases King’s concern for the future of authorship in the digital age and the position of the writer in the book and entertainment industries. This article seeks to trace the trajectory of the concept of the author who is seen moving from print to digital environments and being entangled in new forms of communication with the reader. In particular, King, who leaves control of the narrative story to experts in digital mediation, takes advantage of the new medium’s immediacy, comes closer to the recipients of his works, and manages to re-invent his authorial image while his name turns into a brand.

Views on authorship: survey among academic staffs of the Korean radiologists

International Nuclear Information System (INIS)

Hwang, Seong Su

2004-01-01

The purpose of my survey is to assess the knowledge and views of the academic staff on authorship criteria. 363 academic staff were invited to fill out the survey via e-mail and the responses were collected for two weeks. A one-page questionnaire was prepared and it included 19 questions with three major groups. The first group of questions was demographic information including the responder's age, sex and academic position. The second group of questions was focused on the individual perception and personal experience for authorship on their publications. The last group of questions included awareness and views of authorship criteria established by International Committee of Medical Journal Editors (ICMJE). The responders were grouped according to age, sex and grade. To examine the difference of responses among each group, a Chi square test for categorical variables was performed. The overall response rate to the survey was 39.2% (113/288) and 20.7% (75/363) of e-mail address were undeliverable. The grade of respondents is relatively evenly distributed from fellowship (20%) to professor (22%). Most of the respondents (90.6%) had experienced difficulties with authorship. Although 72.2% of respondents had no awareness of ICMJE's criteria, they agreed with criteria fully (56.1%) and partially (42.4%). 42% of respondents expected that more than 50% of the authors per paper didn't fulfill the authorship criteria. Less than 5 authors per paper were adequate (96%). Most of respondents thought that the introduction of a contribution listing to the Journal of the Korean radiological society is necessary (93.5%) but it is not urgently needed (59.0%). I can see that there are authorship problems among the academic members of Korean radiological society. It is necessary to educate the members and to have them justify the validity of their authorship claims

The Gender of Authorship: Heiner Müller and Christa Wolf

Directory of Open Access Journals (Sweden)

Helen Fehervary

1980-09-01

Full Text Available The relationship between sexuality and politics has always been an underlying assumption of the avant-garde. In recent East German avant-garde literature, the notion of authorship as production has become associated with technological rationality and the patriarchal socialist state. The ensuing crisis of the traditional male author has thus led necessarily to a radicalization of subjectivity and to the politics of gender. A comparison of two contemporary texts, one by a female author, one by a male, shows that the crisis of authorship assumes two distinctly different forms when differences in gender are taken into account. The East German authors Heiner Müller and Christa Wolf have exhibited remarkably similar literary and political developments. Two of their most recent texts, Mülller's Hamletmachine and Wolf's No Place. Nowhere , both address the problematic of traditional male authorship and the disintegration of a preconceived literary gender identity. Yet, these two texts exemplify very different assumptions about the relationship between authorship and the literary tradition. Müller's text suggests the imprisonment of the male author within a petrified system of tradition and images, and hence the necessity of deconstruction. Wolf's text manifests a process of creating a new form of female-identified authorship and the possibility of redefining the tradition of literature and its future.

"Political co-authorships" in medical science journals.

Science.gov (United States)

Johal, Jaspreet; Loukas, Marios; Oskouian, Rod J; Tubbs, R Shane

2017-09-01

The issue of co-author relationships on medical sciences journal publications has become more pronounced as advances in technology have enabled collaboration across countries and institutions to occur much more efficiently. These relationships often have underlying political motivations and outcomes, including career advancement, attempting to increase prestige of a project, and maintaining research grants. Some authors may be listed as senior or honorary authors despite offering little or no contribution to the original research project. This may be done in an effort to enhance the gravitas of a research project, and attain publication in a highly regarded medical journal. The current review covers the topic of political co-authorship and germane literature and lists strategies to combat this phenomenon. Such co-authorship practices corrupt the integrity of the research process as they attempt to bypass the safeguard that medical journals and institutions have put in place to prevent fraud and falsification. A number of strategies have been proposed to combat the practice of co-authorship, but it may ultimately be an unavoidable feature of contemporary medical research publishing that is difficult to police.

2011-10-25

To assess the prevalence of honorary and ghost authors in six leading general medical journals in 2008 and compare this with the prevalence reported by authors of articles published in 1996. Cross sectional survey using a web based questionnaire. International survey of journal authors. Sample of corresponding authors of 896 research articles, review articles, and editorial/opinion articles published in six general medical journals with high impact factors in 2008: Annals of Internal Medicine, JAMA, Lancet, Nature Medicine, New England Journal of Medicine, and PLoS Medicine. Self reported compliance with International Committee of Medical Journal Editors (ICMJE) criteria for authorship for all authors on the selected articles. A total of 630/896 (70.3%) corresponding authors responded to the survey. The prevalence of articles with honorary authorship or ghost authorship, or both, was 21.0% (95% CI 18.0% to 24.3%), a decrease from 29.2% reported in 1996 (P = 0.004). Based on 545 responses on honorary authorship, 96 articles (17.6% (95% CI 14.6% to 21.0%)) had honorary authors (range by journal 12.2% to 29.3%), a non-significant change from 1996 (19.3%; P = 0.439). Based on 622 responses on ghost authorship, 49 articles (7.9% (6.0% to 10.3%)) had ghost authors (range by journal 2.1% to 11.0%), a significant decline from 1996 (11.5%; P = 0.023). The prevalence of honorary authorship was 25.0% in original research reports, 15.0% in reviews, and 11.2% in editorials, whereas the prevalence of ghost authorship was 11.9% in research articles, 6.0% in reviews, and 5.3% in editorials. Evidence of honorary and ghost authorship in 21% of articles published in major medical journals in 2008 suggests that increased efforts by scientific journals, individual authors, and academic institutions are essential to promote responsibility, accountability, and transparency in authorship, and to maintain integrity in scientific publication.

Ren, Xiaopeng; Su, Hong; Lu, Kewen; Dong, Xiawei; Ouyang, Zhengzheng; Talhelm, Thomas

2016-01-01

Unmerited authorship is a practice common to many countries around the world, but are there systematic cultural differences in the practice? We tested whether scientists from collectivistic countries are more likely to add unmerited coauthors than scientists from individualistic countries. We analyzed archival data from top scientific journals (Study 1) and found that national collectivism predicted the number of authors, which might suggest more unmerited authors. Next, we found that collectivistic scientists were more likely to add unmerited coauthors than individualistic scientists, both between cultures (Studies 2-3) and within cultures (Study 4). Finally, we found that priming people with collectivistic self-construal primes made them more likely to endorse questionable authorship attitudes (Study 5). These findings show that culture collectivism is related to unmerited authorship.

The authorship attribution is a problem of considerable practical and technical interest. Several methods have been designed to infer the authorship of disputed documents in multiple contexts. While traditional statistical methods based solely on word counts and related measurements have provided a simple, yet effective solution in particular cases; they are prone to manipulation. Recently, texts have been successfully modeled as networks, where words are represented by nodes linked according to textual similarity measurements. Such models are useful to identify informative topological patterns for the authorship recognition task. However, there is no consensus on which measurements should be used. Thus, we proposed a novel method to characterize text networks, by considering both topological and dynamical aspects of networks. Using concepts and methods from cellular automata theory, we devised a strategy to grasp informative spatio-temporal patterns from this model. Our experiments revealed an outperformance over structural analysis relying only on topological measurements, such as clustering coefficient, betweenness and shortest paths. The optimized results obtained here pave the way for a better characterization of textual networks.

Full Text Available The authorship attribution is a problem of considerable practical and technical interest. Several methods have been designed to infer the authorship of disputed documents in multiple contexts. While traditional statistical methods based solely on word counts and related measurements have provided a simple, yet effective solution in particular cases; they are prone to manipulation. Recently, texts have been successfully modeled as networks, where words are represented by nodes linked according to textual similarity measurements. Such models are useful to identify informative topological patterns for the authorship recognition task. However, there is no consensus on which measurements should be used. Thus, we proposed a novel method to characterize text networks, by considering both topological and dynamical aspects of networks. Using concepts and methods from cellular automata theory, we devised a strategy to grasp informative spatio-temporal patterns from this model. Our experiments revealed an outperformance over structural analysis relying only on topological measurements, such as clustering coefficient, betweenness and shortest paths. The optimized results obtained here pave the way for a better characterization of textual networks.

[AUTHORSHIP - A GREAT HONOR OR AN ONEROUS RESPONSIBILITY?

Over the years ethical issues have been raised regarding authorship of scientific literature. Research is mainly accomplished through teamwork, and publishing articles has a significant impact upon academic promotion and career path. Thus, concepts such as honorary authors, ghost authors, and equally contributing authors have been established. In order to maintain better regulation, authorship recommendation and policies have been developed such as the International Committee of Medical Journal Editors (ICMJE) guidelines. The senior researcher plays an important role in the process of publishing an article. While they may be eager to announce their findings, the senior researcher must first ensure that no falsification, fabrication or plagiarism has been committed, as well as address the sensitive subject of the correct order of authors on the paper. The senior researcher, along with the rest of the authors appearing on the paper, must also be accountable for the data reported in the article. In this editorial, we will review the topic of authorship and explore famous international incidents as well as our own experiences.

Alphabetical co-authorship in the social sciences and humanities: evidence from a comprehensive local database

Energy Technology Data Exchange (ETDEWEB)

Guns, R

2016-07-01

We present an analysis of alphabetical co-authorship in the social sciences and humanities (SSH), based on data from the VABB-SHW, a comprehensive database of SSH research output in Flanders (2000-2013). Using an unbiased estimator of the share of intentional alphabetical co-authorship (IAC), we find that alphabetical co-authorship is more engrained in SSH than in science as a whole. Within the SSH, large differences exist between disciplines. The highest proportions of IAC are found for Literature, Economics & business, and History. Furthermore, alphabetical co-authorship varies with publication type: it occurs most often in books, is less common in articles in journals or in books, and is rare in proceedings papers. The use of alphabetical co-authorship appears to be slowly declining. (Author)

Authors, authorship order, the moving finger writes

Jayakumar Avula

2015-01-01

Full Text Available There has been a phenomenal increase in the number of research papers with multiple authors. Increasing academic pressures and halo around individuals with prolific publications have made many aspirants to claim authorship. Increasing number of authors has brought its own issues of author credits, disputes, rivalry, and a degree of unwelcome scramble for credit sharing. Many unresolved issues about authorship and various guidelines and admonitions are more often infringed than adhered to. The position of the first and last author seem to be well recognized in medical and dental journals, but the fate of middle authors is left to guessing and often of inconsequential importance. Most of these issues, as well as fraud, misconduct in medical research publications, have been discussed amply but too of no avail. It is comforting to know that except for small shouts and whispers, dental research has been relatively free from scams and frauds. The complacency, however, needs to be tempered with constant vigil against fraud, falsification and fabrication of research reports. Honest authorship, vigilant editors, robust peer review, and a discerning readership are the sine qua non for a good research paper. Academic institutions and selection committees should be concentrating on the quality of research papers and not enamored of their number.

Culture and Unmerited Authorship Credit: Who Wants It and Why?

Unmerited authorship is a practice common to many countries around the world, but are there systematic cultural differences in the practice? We tested whether scientists from collectivistic countries are more likely to add unmerited coauthors than scientists from individualistic countries. We analyzed archival data from top scientific journals (Study 1) and found that national collectivism predicted the number of authors, which might suggest more unmerited authors. Next, we found that collectivistic scientists were more likely to add unmerited coauthors than individualistic scientists, both between cultures (Studies 2–3) and within cultures (Study 4). Finally, we found that priming people with collectivistic self-construal primes made them more likely to endorse questionable authorship attitudes (Study 5). These findings show that culture collectivism is related to unmerited authorship. PMID:28082940

We aimed to assess which factors correlate with collaborative behavior and whether such behavior associates with scientific impact (citations and becoming a principal investigator). We used the R index which is defined for each author as log(Np)/log(I1), where I1 is the number of co-authors who appear in at least I1 papers written by that author and Np are his/her total papers. Higher R means lower collaborative behavior, i.e. not working much with others, or not collaborating repeatedly with the same co-authors. Across 249,054 researchers who had published ≥30 papers in 2000-2015 but had not published anything before 2000, R varied across scientific fields. Lower values of R (more collaboration) were seen in physics, medicine, infectious disease and brain sciences and higher values of R were seen for social science, computer science and engineering. Among the 9,314 most productive researchers already reaching Np ≥ 30 and I1 ≥ 4 by the end of 2006, R mostly remained stable for most fields from 2006 to 2015 with small increases seen in physics, chemistry, and medicine. Both US-based authorship and male gender were associated with higher values of R (lower collaboration), although the effect was small. Lower values of R (more collaboration) were associated with higher citation impact (h-index), and the effect was stronger in certain fields (physics, medicine, engineering, health sciences) than in others (brain sciences, computer science, infectious disease, chemistry). Finally, for a subset of 400 U.S. researchers in medicine, infectious disease and brain sciences, higher R (lower collaboration) was associated with a higher chance of being a principal investigator by 2016. Our analysis maps the patterns and evolution of collaborative behavior across scientific disciplines.

Reconstructing Faculty Roles to Align with Self- Authorship Development: The Gentle Art of Stepping Back

Deborah A. Day

2014-11-01

Full Text Available Student development has connections to important academic purposes in higher education (King, Baxter Magolda, Barber, Kendall Brown & Lindsay, 2009. In particular, a growing body of work on self-authorship, a social-constructive theory of development, has demonstrated relevance to the purposes of higher education (Baxter Magolda, 2001; King & Baxter Magolda, 2004. The conditions which support self-authorship development in academic settings have been studied in detail, drawing attention to what King et al. (2009 frame as developmentally effective educational experiences. Explorations of self-authorship development in academic settings have focused on students’ experiences and outcomes. The classroom experiences of faculty, particularly those working outside institutional initiatives, to support self-authorship have received less attention. This study used a theory-driven (Baxter Magolda, 2001; Pizzolato, 2005, practice-based research framework, to explore a faculty-student affairs collaboration through participant observation as the collaborators sought to align their teaching practices with the tenets of self-authorship development in the context of a senior undergraduate course in Service-Learning. Four themes emerged, which have relevance for those who wish to consider student personal and academic development concurrently. We argue that individual faculty members can collaborate with student affairs professionals and use self-authorship theory to expand their constructions of what it means to be a “good professor” by approaching teaching as a mirror image of the self-authorship journey traveled by students.

Measuring co-authorship and networking-adjusted scientific impact.

Appraisal of the scientific impact of researchers, teams and institutions with productivity and citation metrics has major repercussions. Funding and promotion of individuals and survival of teams and institutions depend on publications and citations. In this competitive environment, the number of authors per paper is increasing and apparently some co-authors don't satisfy authorship criteria. Listing of individual contributions is still sporadic and also open to manipulation. Metrics are needed to measure the networking intensity for a single scientist or group of scientists accounting for patterns of co-authorship. Here, I define I(1) for a single scientist as the number of authors who appear in at least I(1) papers of the specific scientist. For a group of scientists or institution, I(n) is defined as the number of authors who appear in at least I(n) papers that bear the affiliation of the group or institution. I(1) depends on the number of papers authored N(p). The power exponent R of the relationship between I(1) and N(p) categorizes scientists as solitary (R>2.5), nuclear (R = 2.25-2.5), networked (R = 2-2.25), extensively networked (R = 1.75-2) or collaborators (Raccountable co-authorship behaviour in published articles.

Authorship and Moral Rights in Video Games

Full Text Available The complex and multimedia nature of video games results in several original and derivative works of copyright contained in a single game. Although there is no need to establish a new category of work and the current state of law offers comprehensive protection of the works, it also means there can be many different authors in a single production, so assignment of rights can be difficult.This interrelation of works and their respective authors can also have a negative effect on authors' moral rights, or, more specifically, the right to claim authorship and the right to object to derogatory treatment of the work.This article analyses the current law of the United Kingdom with regard to authorship and ownership of copyright in video games and underlying works before analysing and evaluating the moral rights of video games' contributors.

Scientific collaboration is among the most important subjects in scientometrics, and many studies have investigated this concept to this day. The goal of the current study is investigation of scientific collaboration and co-authorship patterns of researchers in the field of library and information science in Iran between years 2005 and 2009. The current study uses scientometrics method. The statistical population consists of 942 documents published in Iranian library and information science journals between years 2005 and 2009. Collaboration coefficient, collaboration index (CI), and degree of collaboration (DC) were used for data analysis. The findings showed that among 942 investigated documents, 506 documents (53.70%) was created by one individual researcher and 436 documents (46.30%) were the result of collaboration between two or more researchers. Also, the highest rank of different authorship patterns belonged to National Journal of Librarianship and Information Organization (code H). The average collaboration coefficient for the library and information science researchers in the investigated time frame was 0.23. The closer this coefficient is to 1, the higher is the level of collaboration between authors, and a coefficient near zero shows a tendency to prefer individual articles. The highest collaboration index with an average of 1.92 authors per paper was seen in year 1388. The five year collaboration index in library and information science in Iran was 1.58, and the average degree of collaboration between researchers in the investigated papers was 0.46, which shows that library and information science researchers have a tendency for co-authorship. However, the co-authorship had increased in recent years reaching its highest number in year 1388. The researchers' collaboration coefficient also shows relative increase between years 1384 and 1388. National Journal of Librarianship and Information Organization has the highest rank among all the investigated

To publish became almost compulsory in Medicine. There is no doubt about the importance of publishing research, but the ordering of its authors is not easy. The lack of internationally accepted criteria led to the establishment of several groups or conventions particularized medical and scientific sectors. To present numerical method to establish rule of value to people who carried out the research, and whether or not incorporated as authors. The proposed score is based on the needs of each step when conducting a scientific work. They were divided into topics in which the main ones were: 1) scientific criteria for authorship; 2) create the idea that originated the work and develop hypotheses; 3) structure the method of work; 4) guiding the work; 5) write the manuscript; 6) coordinate the group that carried out the work; 7) reviewing the literature; 8) suggestions incorporated into the work; 9) to solve fundamental problems of labor; 10) to collect data; 11) presentation at scientific meetings; 12 ) lead the job and raise funds; 13) providing patients or material; 14) to do the routine needs; 15) specific fee to participate; 16) criteria for ranking the authors; 17) honorary author; 18) usurpation of the main authorship, 19) acknowledgments . It is important to emphasize that, to prevent major conflicts, the group that is willing to conduct a scientific work should establish at the outset, as objectively as possible, the criteria to be adopted for distribution of authorship. The subjective criteria here proposed avoid interference and prevent conflicts of interest.

Teaching authorship and publication practices in the biomedical and life sciences.

Macrina, Francis L

2011-06-01

Examination of a limited number of publisher's Instructions for Authors, guidelines from two scientific societies, and the widely accepted policy document of the International Committee of Medical Journal Editors (ICMJE) provided useful information on authorship practices. Three of five journals examined (Nature, Science, and the Proceedings of the National Academy of Sciences) publish papers across a variety of disciplines. One is broadly focused on topics in medical research (New England Journal of Medicine) and one publishes research reports in a single discipline (Journal of Bacteriology). Similar elements of publication policy and accepted practices were found across the policies of these journals articulated in their Instructions for Authors. A number of these same elements were found in the professional society guidelines of the Society for Neuroscience and the American Chemical Society, as well as the ICMJE Uniform Requirements for Manuscripts Submitted to Biomedical Journals. Taken together, these sources provide the basis for articulating best practices in authorship in scientific research. Emerging from this material is a definition of authorship, as well as policy statements on duplicative publication, conflict of interest disclosure, electronic access, data sharing, digital image integrity, and research requiring subjects' protection, including prior registration of clinical trials. These common elements provide a foundation for teaching about scientific authorship and publication practices across biomedical and life sciences disciplines.

Authorship ethics in global health research partnerships between researchers from low or middle income countries and high income countries.

Smith, Elise; Hunt, Matthew; Master, Zubin

2014-05-28

Over the past two decades, the promotion of collaborative partnerships involving researchers from low and middle income countries with those from high income countries has been a major development in global health research. Ideally, these partnerships would lead to more equitable collaboration including the sharing of research responsibilities and rewards. While collaborative partnership initiatives have shown promise and attracted growing interest, there has been little scholarly debate regarding the fair distribution of authorship credit within these partnerships. In this paper, we identify four key authorship issues relevant to global health research and discuss their ethical and practical implications. First, we argue that authorship guidance may not adequately apply to global health research because it requires authors to write or substantially revise the manuscript. Since most journals of international reputation in global health are written in English, this would systematically and unjustly exclude non-English speaking researchers even if they have substantially contributed to the research project. Second, current guidance on authorship order does not address or mitigate unfair practices which can occur in global health research due to power differences between researchers from high and low-middle income countries. It also provides insufficient recognition of "technical tasks" such as local participant recruitment. Third, we consider the potential for real or perceived editorial bias in medical science journals in favour of prominent western researchers, and the risk of promoting misplaced credit and/or prestige authorship. Finally, we explore how diverse cultural practices and expectations regarding authorship may create conflict between researchers from low-middle and high income countries and contribute to unethical authorship practices. To effectively deal with these issues, we suggest: 1) undertaking further empirical and conceptual research regarding

Emerging Politics of Authorship: Recovering Collectivity, Negotiating the Risk

Directory of Open Access Journals (Sweden)

Andrea Pisac

2011-12-01

Full Text Available This article examines authorship as a socially embedded process by challenging Western notions of the autonomous creative genius. It considers social interactions between various agents in the field of literary production which in turn recovers the collective nature of modern authorship. Far from leaving it unexamined, it further contextualises authorial collectivity and its role in the emerging model of authorship. Questions and arguments raised in this article are informed by the ethnographic data collected during my doctoral research focusing on the reception of post-1990s ex-Yugoslav literature on the UK book market. Such ethnographic approach to literary translations – i.e. the micro-level analysis of social interactions that ‘create’ literature – demonstrated how the author is ‘created’ in the communication of two literary systems through linguistic translation as well as re-translations of symbolic and social capitals. My research was concerned with analysing the ‘backstage’ of the publishing industry – informal networks and international literary geopolitics – which all contributed to debunking the myth of the autonomous creative genius. However, instead of retracing my steps, this article outlines new avenues and questions that such analysis has opened up. One such question is how new technologies are (reconstructing and (repositioning the role of the author.

To investigate changes over a 20-year period in authorship and characteristics of articles in pharmacy journals. All articles published in the American Journal of Health-System Pharmacy, The Annals of Pharmacotherapy, and Pharmacotherapy in 1989, 1999, and 2009 were reviewed. Data collected for each article included article type, number of authors, number of physician authors, whether any author was affiliated with a pharmaceutical company, and source of funding. The number of articles included was 574 in 1989, 659 in 1999, and 589 in 2009. The mean number of authors per article increased from 2.5 in 1989 to 2.8 in 1999 and 3.6 in 2009 (p6 authors) increased from 2% in 1989 to 3% in 1999 and 9% in 2009 (pInternational Committee of Medical Journal Editors.

Authorship matrix: a rational approach to quantify individual contributions and responsibilities in multi-author scientific articles.

Science.gov (United States)

Clement, T Prabhakar

2014-06-01

We propose a rational method for addressing an important question-who deserves to be an author of a scientific article? We review various contentious issues associated with this question and recommend that the scientific community should view authorship in terms of contributions and responsibilities, rather than credits. We propose a new paradigm that conceptually divides a scientific article into four basic elements: ideas, work, writing, and stewardship. We employ these four fundamental elements to modify the well-known International Committee of Medical Journal Editors (ICMJE) authorship guidelines. The modified ICMJE guidelines are then used as the basis to develop an approach to quantify individual contributions and responsibilities in multi-author articles. The outcome of the approach is an authorship matrix, which can be used to answer several nagging questions related to authorship.

A comparative study on the reliability of co-authorship networks with emphases on edges and nodes

Full Text Available A scientific co-authorship network may be modeled by a graph G composed of k nodes and m edges. Researchers that make up this network may be interpreted as its nodes and the link between these agents (co-authored papers as its edges. Current work evaluated and compared the reliability measure of networks with two emphases: 1 On nodes (perfectly reliable edges and 2 On edges (perfectly reliable nodes. Specifically, the reliability of a fictitious co-authorship network at a given time t was analyzed taking into account, first, the reliability of nodes (researchers equal and different, and, second, the reliability of edges (co-authorship relations, equal and different. Additionally, centrality measures of nodes were obtained to identify situations where the insertion of an edge significantly increased the reliability of the network. Results showed that the reliability of the co-authorship network focusing on edges is more sensitive to changes in individual reliabilities than the reliability of the network focusing on nodes. Additionally, the use of centrality measures was viable to identify possible insertions of edges or co-authorship relations to increase the reliability of the network in the two approaches.

Studies have shown that women in emergency medicine (EM) lag behind their male counterparts in academic productivity. We compared the proportion of female attending physicians from EM academic programs to the proportion of female first or second authors of original scientific manuscripts and case reports from four major EM journals in a single year. We used a retrospective cross-sectional design. Original scientific manuscripts and case reports from four major EM journals published in 2005: Academic Emergency Medicine, Annals of Emergency Medicine, American Journal of Emergency Medicine, and Journal of Emergency Medicine were reviewed to determine genders of first and second authors. The proportion of female first or second authorship was then compared to the proportion of female EM attending physicians from 134 academic EM programs in the United States. Data were analyzed using Pearson's chi-squared and Clopper-Pearson binomial confidence intervals as appropriate. A p-value of ≤ 0.05 was considered significant. The percentage of female faculty; 940/3571 (26.32%, 95% confidence interval [CI] 24.9-27.8%) vs. the percentage of female first or second authorship 289/1123 (25.73%, 95% CI 23.3-28.4%) was not statistically significant (p = 0.562). There was no difference in the proportion of male and female authors with multiple manuscripts (p = 0.889). As measured by first and second authorship, there was no discrepancy between the proportion of female EM faculty and the proportion of female authorship in EM literature from 2005.

Twenty-year trends of authorship and sampling in applied biomechanics research.

Science.gov (United States)

Knudson, Duane

2012-02-01

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

Authors and authorship in brazilian information science journals

2003-01-01

Full Text Available This article discusses issues of authorship. It presents the analysis of 86 journal articles with 1528 bibliographical entries. The articles were all published in 2001 in four Brazilian journals of Information Science. Several characteristics of the authors were considered. Among them are the authors’ academic qualification, function and job held; individual and joint authorship, language of publication, papers published by sex and nationality and self-citation. Data show that the most significant number of papers are published by the academic community; they also show that publishing partnerships are more common among members of the same academic institution and that the male contribution to publications has lately increased. The analysis furthermore shows that self-citations privilege papers given at academic events and articles. However the preferred citations in articles are book chapters, journal articles and electronic texts. Finally, data show that most of the referred bibliography is recent, but they also show a certain degree of inbreeding since there are few references of interdisciplinary nature.

Perceptions of Scholars in the Field of Economics on Co-Authorship Associations: Evidence from an International Survey.

Kumar, Sameer; Ratnavelu, Kuru

2016-01-01

Scholars (n = 580) from 69 countries who had contributed articles in the field of Economics during the year 2015 participated in a survey that gauged their perceptions of various aspects of co-authorship, including its benefits, motivations, working relationships, order of authorship and association preferences. Among the main findings, significant differences emerged in the proportion of co-authored papers based on age, gender and number of years the researchers had spent in their present institution. Female scholars had a greater proportion of co-authored papers than male scholars. Respondents considered improved quality of paper, contribution of mutual expertise, and division of labor as the biggest benefits of and motivation for co-authorship. Contrary to common perceptions that Economics researchers used a predominantly alphabetical order of authorship, our study found that a considerable percentage of respondents (34.5%) had practiced an order of authorship based on the significance of the authors' contribution to the work. The relative importance of tasks differed significantly according to whether researchers co-authored as mentors or co-authored as colleagues. Lastly, researchers were found to associate, to varying degrees, with other researchers based on socio-academic parameters, such as nationality, ethnicity, gender, professional position and friendship. The study indicates that Economics authors perceive co-authorship as a rewarding endeavor. Nonetheless, the level of contribution and even the choice of association itself as a co-author depends to a great extent on the type of working relationship and socio-academic factors.

 To examine the association between the presence of individual principal investigators' financial ties to the manufacturer of the study drug and the trial's outcomes after accounting for source of research funding.  Cross sectional study of randomized controlled trials (RCTs).  Studies published in "core clinical" journals, as identified by Medline, between 1 January 2013 and 31 December 2013.  Random sample of RCTs focused on drug efficacy.  Association between financial ties of principal investigators and study outcome.  A total of 190 papers describing 195 studies met inclusion criteria. Financial ties between principal investigators and the pharmaceutical industry were present in 132 (67.7%) studies. Of 397 principal investigators, 231 (58%) had financial ties and 166 (42%) did not. Of all principal investigators, 156 (39%) reported advisor/consultancy payments, 81 (20%) reported speakers' fees, 81 (20%) reported unspecified financial ties, 52 (13%) reported honorariums, 52 (13%) reported employee relationships, 52 (13%) reported travel fees, 41 (10%) reported stock ownership, and 20 (5%) reported having a patent related to the study drug. The prevalence of financial ties of principal investigators was 76% (103/136) among positive studies and 49% (29/59) among negative studies. In unadjusted analyses, the presence of a financial tie was associated with a positive study outcome (odds ratio 3.23, 95% confidence interval 1.7 to 6.1). In the primary multivariate analysis, a financial tie was significantly associated with positive RCT outcome after adjustment for the study funding source (odds ratio 3.57 (1.7 to 7.7). The secondary analysis controlled for additional RCT characteristics such as study phase, sample size, country of first authors, specialty, trial registration, study design, type of analysis, comparator, and outcome measure. These characteristics did not appreciably affect the relation between financial ties and study outcomes (odds ratio 3.37, 1

Writing a research paper at the university: authorship vs plagiarism

Full Text Available Considering the need of producing academic texts at the university, many undergraduate students do it by copying texts that were already published. In this study we discuss the presence of plagiarism versus authorship marks in the introduction of academic articles produced by freshmen in a licenciateship degree. Therefore, we emphasize the issue of plagiarism and authorship, particularly from the perspective of the enunciative bakhtinian studies and then present the theoretical basis of Literacies, with the most recent studies on Literacies and Socio-Rhetorics. Data analysis revealed and confirmed the academic writing as a complex activity, given the practice of plagiarism found in the analyzed productions. The lack of knowledge of academic writing together not the theme domain contributed to the practice of plagiarism.

The research activities of the computational physicists utilizing high performance computing are analyzed by bibliometirc approaches. This study aims at providing the computational physicists utilizing high-performance computing and policy planners with useful bibliometric results for an assessment of research activities. In order to achieve this purpose, we carried out a co-authorship network analysis of journal articles to assess the research activities of researchers for high-performance computational physics as a case study. For this study, we used journal articles of the Scopus database from Elsevier covering the time period of 2004-2013. We extracted the author rank in the physics field utilizing high-performance computing by the number of papers published during ten years from 2004. Finally, we drew the co-authorship network for 45 top-authors and their coauthors, and described some features of the co-authorship network in relation to the author rank. Suggestions for further studies are discussed.

Authorship attribution is to identify the most likely author of a given sample among a set of candidate known authors. It can be not only applied to discover the original author of plain text, such as novels, blogs, emails, posts etc., but also used to identify source code programmers. Authorship attribution of source code is required in diverse applications, ranging from malicious code tracking to solving authorship dispute or software plagiarism detection. This paper aims to propose a new method to identify the programmer of Java source code samples with a higher accuracy. To this end, it first introduces back propagation (BP) neural network based on particle swarm optimization (PSO) into authorship attribution of source code. It begins by computing a set of defined feature metrics, including lexical and layout metrics, structure and syntax metrics, totally 19 dimensions. Then these metrics are input to neural network for supervised learning, the weights of which are output by PSO and BP hybrid algorithm. The effectiveness of the proposed method is evaluated on a collected dataset with 3,022 Java files belong to 40 authors. Experiment results show that the proposed method achieves 91.060% accuracy. And a comparison with previous work on authorship attribution of source code for Java language illustrates that this proposed method outperforms others overall, also with an acceptable overhead.

Scientific collaboration is very important, as it is the basis of the scientific development of every discipline. The aim of this paper is to identify the indicators of scientific collaboration and co-authorship networks of Spanish researchers and institutions publishing in national and international paediatric, multidisciplinary or other knowledge areas journals during the period 2006-2010. The papers studied were obtained from the databases including, Science Citation Index Expanded, Scopus, Índice Médico Español and Índice Bibliográfico Español en Ciencias de la Salud, by means of applying different search profiles. All the papers signed by co-authors were quantified in order to identify the authorship and institutional collaboration networks. Furthermore the degree, betweenness index, and closeness index were obtained as a measurement of the structural analysis. Co-authorships were represented graphically by the network analysis and display software Pajek. A total of 7971 articles were published during the period 2006-2010, with 90.55% completed in collaboration. Using a threshold of 10 or more co-authorships, 77 research groups in Pediatrics were identified. Most papers were published in collaboration between institutions of the same Autonomous Community (42.28%), and 14.84% with international collaboration. The analysis of institutional participation enabled a large nucleus or institutional collaboration network to be identified, with 52 linked institutions. International collaboration was led by the USA and European countries, such as United Kingdom, Germany and Italy. Authors, institutions and the most active working groups in Spanish pediatrics were identified, which is very interesting information to establish contacts to increase the existing networks, to prevent redundancies, and to take advantage of the new emerging groups. It is necessary to promote the collaboration of Spanish researchers, especially with their international colleagues, since a

Full Text Available Collaboration among scholars and institutions is progressively becoming essential to the success of research grant procurement and to allow the emergence and evolution of scientific disciplines. Our work focuses on analysing if the volume of collaborations of one author together with the relevance of his collaborators is somewhat related to his research performance over time. In order to prove this relation we collected the temporal distributions of scholars' publications and citations from the Google Scholar platform and the co-authorship network (of Computer Scientists underlying the well-known DBLP bibliographic database. By the application of time series clustering, social network analysis and non-parametric statistics, we observe that scholars with similar publications (citations patterns also tend to have a similar centrality in the co-authorship network. To our knowledge, this is the first work that considers success evolution with respect to co-authorship.

Full Text Available Background: Co-authorship is one of the most tangible forms of research collaboration. A co-authorship network is a social network in which the authors through participation in one or more publication through an indirect path have linked to each other. The present research using the social network analysis studied co-authorship network of 681 articles published in Journal of Research in Medical Sciences (JRMS during 2008-2012. Materials and Methods: The study was carried out with the scientometrics approach and using co-authorship network analysis of authors. The topology of the co-authorship network of 681 published articles in JRMS between 2008 and 2012 was analyzed using macro-level metrics indicators of network analysis such as density, clustering coefficient, components and mean distance. In addition, in order to evaluate the performance of each authors and countries in the network, the micro-level indicators such as degree centrality, closeness centrality and betweenness centrality as well as productivity index were used. The UCINET and NetDraw softwares were used to draw and analyze the co-authorship network of the papers. Results: The assessment of the authors productivity in this journal showed that the first ranks were belonged to only five authors, respectively. Furthermore, analysis of the co-authorship of the authors in the network demonstrated that in the betweenness centrality index, three authors of them had the good position in the network. They can be considered as the network leaders able to control the flow of information in the network compared with the other members based on the shortest paths. On the other hand, the key role of the network according to the productivity and centrality indexes was belonged to Iran, Malaysia and United States of America. Conclusion: Co-authorship network of JRMS has the characteristics of a small world network. In addition, the theory of 6° separation is valid in this network was also true.

Networks that represent connections between individuals can be valuable analytic tools. The Social Network Cytoscape app is capable of creating a visual summary of connected individuals automatically. It does this by representing relationships as networks where each node denotes an individual and an edge linking two individuals represents a connection. The app focuses on creating visual summaries of individuals connected by co-authorship links in academia, created from bibliographic databases like PubMed, Scopus and InCites. The resulting co-authorship networks can be visualized and analyzed to better understand collaborative research networks or to communicate the extent of collaboration and publication productivity among a group of researchers, like in a grant application or departmental review report. It can also be useful as a research tool to identify important research topics, researchers and papers in a subject area.

César Ortega Esquembre

2017-08-01

Full Text Available The aim of this paper is to study the Jürgen Habermas´s vision of genetic manipulation; in particular, it will be addressed critically his assumption that the genetically engineered person would loose his awareness of authorship. In the author´s view, positive genetic intervention —one that is to genetically enhance the subject— would eliminate the awareness of authorship of that subject, as well as his self-understanding as moral agent. Two aspects of the question will be approached: firstly, the correctness or incorrectness of Habermas´s thesis. Secondly, the relevance of the thesis to oppose positive eugenics. Could be other arguments considered within Habermas´s conceptual framework to oppose positive eugenics?

Publications are an important tool to measure one's success and achievement in academia. They can help propel a career forward and move one into a position of leadership. The overall purpose of this study was to investigate changes in bibliometric variables, authorship, and collaboration trends in the Journal of Orthopaedic Research (JOR®), since its inception in 1983. A bibliometric analysis was completed for all manuscripts meeting the inclusion criteria (638), which were published throughout the inaugural year plus one representative year of each decade. Several parameters were investigated including numbers of manuscripts, authors, collaborating institutions/countries, references, pages, and citations; region of origin and gender of authors over time and by region were main focuses. Significant increases over time were observed in all bibliometric variables analyzed except in the number of pages and citations. There was an approximate 27% point increase for both female first and corresponding authors from 1983 to 2015. While this is most likely due to the increase in the number of women that have entered the field over time, similar increases in the percentage of women holding positions on the JOR editorial board or in leadership positions within in the field may have also contributed to improvements in gender parity. Understanding changes in publishing characteristics over time, by region, and by gender are critical, especially with the rising demands of publishing in academia. JOR has seen increase in most variables analyzed, including improvements in authorship by women in the field of orthopaedic research. © 2018 Orthopaedic Research Society.

The Disputed Authorship of a Medieval Text: A New Solution to the Attribution Problem in the Case of Guillaume D’Angleterre

Directory of Open Access Journals (Sweden)

Maria Slautina

2012-11-01

Full Text Available This paper presents a case of disputed authorship concerning a literary medieval text, the Old French romance Guillaume d’Angleterre, and describes a new attempt to use the mathematical method of authorship attribution called the "method of pattern recognition”. After presenting an overview of previous approaches to the problem of the authorship of this text, I argue for the advantages of a statistical syntactic based method for authorship attribution of medieval texts. The method of pattern recognition consists in the identification of a domain of syntactic parameters and a measurement of the proximity or distance of texts as located in a multi-dimensional syntactic space. I find that the medieval text most likely belongs to Chrétien de Troyes, one of the most famous French authors of the twelfth century. I present for the first time an attempt to apply the method of pattern recognition to determine the authorship of a medieval text written in Old French.

Explaining international co-authorship in global environmental change research

Energy Technology Data Exchange (ETDEWEB)

Jappe, A.

2006-04-15

This paper maps the domain of earth and environmental sciences (EES) and investigates the relationship between cognitive problem structures and internationalisation patterns, drawing on the concepts of systemic versus cumulative global environmental change (GEC) and mutual task dependence in scientific fields. We find that scientific output concentration and internationalisation are significantly higher in the systemic GEC fields of Meteorology and Atmospheric Sciences and Oceanography than in the cumulative GEC fields Ecology and Water Resources. The relationship is explained by stronger mutual task dependence in systemic GEC fields. In contrast, the portion of co-authorships with developing, emerging and transition countries among all international publications is larger for Water Resources than for the three other fields, consistent with the most pressing needs for STI capacity development in these countries.

Non-Traditional Authorship Attribution Studies of William Shakespeare’s Canon: Some Caveats

Directory of Open Access Journals (Sweden)

Joseph Rudman

2016-03-01

Full Text Available The paper looks at the problems in conducting non-traditional authorship attribution studies on the canon of William Shakespeare. After a short introduction, the case is put forth that these studies are ‘scientific’ and must adhere to the tenets of the scientific method. By showing that a complete and valid experimental plan is necessary and pointing out the many and varied pitfalls (e.g., the text, the control groups, the treatment of errors, it becomes clear what a valid study of Shakespearean non-traditional authorship attribution demands. I then come to the conclusion that such a valid study is not attainable with the limits of present-day knowledge.

Hierarchical and Non-Hierarchical Linear and Non-Linear Clustering Methods to “Shakespeare Authorship Question”

Directory of Open Access Journals (Sweden)

Refat Aljumily

2015-09-01

Full Text Available A few literary scholars have long claimed that Shakespeare did not write some of his best plays (history plays and tragedies and proposed at one time or another various suspect authorship candidates. Most modern-day scholars of Shakespeare have rejected this claim, arguing that strong evidence that Shakespeare wrote the plays and poems being his name appears on them as the author. This has caused and led to an ongoing scholarly academic debate for quite some long time. Stylometry is a fast-growing field often used to attribute authorship to anonymous or disputed texts. Stylometric attempts to resolve this literary puzzle have raised interesting questions over the past few years. The following paper contributes to “the Shakespeare authorship question” by using a mathematically-based methodology to examine the hypothesis that Shakespeare wrote all the disputed plays traditionally attributed to him. More specifically, the mathematically based methodology used here is based on Mean Proximity, as a linear hierarchical clustering method, and on Principal Components Analysis, as a non-hierarchical linear clustering method. It is also based, for the first time in the domain, on Self-Organizing Map U-Matrix and Voronoi Map, as non-linear clustering methods to cover the possibility that our data contains significant non-linearities. Vector Space Model (VSM is used to convert texts into vectors in a high dimensional space. The aim of which is to compare the degrees of similarity within and between limited samples of text (the disputed plays. The various works and plays assumed to have been written by Shakespeare and possible authors notably, Sir Francis Bacon, Christopher Marlowe, John Fletcher, and Thomas Kyd, where “similarity” is defined in terms of correlation/distance coefficient measure based on the frequency of usage profiles of function words, word bi-grams, and character triple-grams. The claim that Shakespeare authored all the disputed

Comparing intermittency and network measurements of words and their dependence on authorship

International Nuclear Information System (INIS)

Amancio, Diego Raphael; Oliveira, Osvaldo N Jr; Fontoura Costa, Luciano da; Altmann, Eduardo G

2011-01-01

Many features of texts and languages can now be inferred from statistical analyses using concepts from complex networks and dynamical systems. In this paper, we quantify how topological properties of word co-occurrence networks and intermittency (or burstiness) in word distribution depend on the style of authors. Our database contains 40 books by eight authors who lived in the nineteenth and twentieth centuries, for which the following network measurements were obtained: the clustering coefficient, average shortest path lengths and betweenness. We found that the two factors with stronger dependence on authors were skewness in the distribution of word intermittency and the average shortest paths. Other factors such as betweenness and Zipf's law exponent show only weak dependence on authorship. Also assessed was the contribution from each measurement to authorship recognition using three machine learning methods. The best performance was about 65% accuracy upon combining complex networks and intermittency features with the nearest-neighbor algorithm of automatic authorship. From a detailed analysis of the interdependence of the various metrics, it is concluded that the methods used here are complementary for providing short- and long-scale perspectives on texts, which are useful for applications such as the identification of topical words and information retrieval.

Lin, Tony R; Kocher, Neil J; Klausner, Adam P; Raman, Jay D

2017-12-01

To further evaluate the academic representation of female urology residents in the United States, we reviewed abstracts from the Mid-Atlantic American Urological Association (MA-AUA) sectional meetings to determine if the recent increase in the number of female urology residents mirrored an increase in this group's abstract authorship. Full text abstracts from the MA-AUA meetings were analyzed from 2008 to 2014 excluding 1 joint section meeting. First-author gender was determined by querying publicly available institutional websites, social media platforms, and the U.S. News & World Report. First-author gender was indeterminable in 10 abstracts based on search criteria and these were excluded. Individual abstracts were broadly categorized based on keywords into 1 of several topics. Chi-square statistical tests examined the relationship between first-authorship gender, publication year, and abstract category. The number of female urology residents in the MA-AUA increased over the study period. A total of 484 abstracts were analyzed. Three hundred ninety-three abstracts (81%) included a male first-author, whereas 81 abstracts (17%) included a female first-author. Female first-authorship ranged from 13% to 25% annually. Comparison of male-to-female first-authorship was statistically significant in all years evaluated (P <.001). There was a statistically significant difference between male and female first-authorship in all topic categories (P <.01), except Education/Other (P = .56). Despite continued gains and increasing female representation in urology, these data highlight significantly fewer female first-authors at the regional Mid-Atlantic section meetings. Larger studies are necessary to identify contributing factors and further areas for improvement toward decreasing gender imbalances within the academic community. Copyright © 2017 Elsevier Inc.

Young, Taryn; Garner, Paul

2017-01-01

Objectives To document low/middle-income country (LMIC) health researchers’ views about authorship, redundant publication, plagiarism and conflicts of interest and how common poor practice was in their institutions. Design We developed a questionnaire based on scenarios about authorship, redundant publication, plagiarism and conflicts of interest. We asked participants whether the described practices were acceptable and whether these behaviours were common at their institutions. We conducted in-depth interviews with respondents who agreed to be interviewed. Participants We invited 607 corresponding authors of Cochrane reviews working in LMICs. From the 583 emails delivered, we obtained 199 responses (34%). We carried out in-depth interviews with 15 respondents. Results Seventy-seven per cent reported that guest authorship occurred at their institution, 60% reported text recycling. For plagiarism, 12% of respondents reported that this occurred ‘occasionally’, and 24% ‘rarely’. Forty per cent indicated that their colleagues had not declared conflicts of interest in the past. Respondents generally recognised poor practice in scenarios but reported that they occurred at their institutions. Themes identified from in-depth interviews were (1) authorship rules are simple in theory, but not consistently applied; (2) academic status and power underpin behaviours; (3) institutions and culture fuel bad practices and (4) researchers are uncertain about what conflict of interests means and how this may influence research. Conclusions LMIC researchers report that guest authorship is widely accepted and common. While respondents report that plagiarism and undeclared conflicts of interest are unacceptable in practice, they appear common. Determinants of poor practice relate to academic status and power, fuelled by institutional norms and culture. PMID:29170291

2017-11-22

To document low/middle-income country (LMIC) health researchers' views about authorship, redundant publication, plagiarism and conflicts of interest and how common poor practice was in their institutions. We developed a questionnaire based on scenarios about authorship, redundant publication, plagiarism and conflicts of interest. We asked participants whether the described practices were acceptable and whether these behaviours were common at their institutions. We conducted in-depth interviews with respondents who agreed to be interviewed. We invited 607 corresponding authors of Cochrane reviews working in LMICs. From the 583 emails delivered, we obtained 199 responses (34%). We carried out in-depth interviews with 15 respondents. Seventy-seven per cent reported that guest authorship occurred at their institution, 60% reported text recycling. For plagiarism, 12% of respondents reported that this occurred 'occasionally', and 24% 'rarely'. Forty per cent indicated that their colleagues had not declared conflicts of interest in the past. Respondents generally recognised poor practice in scenarios but reported that they occurred at their institutions. Themes identified from in-depth interviews were (1) authorship rules are simple in theory, but not consistently applied; (2) academic status and power underpin behaviours; (3) institutions and culture fuel bad practices and (4) researchers are uncertain about what conflict of interests means and how this may influence research. LMIC researchers report that guest authorship is widely accepted and common. While respondents report that plagiarism and undeclared conflicts of interest are unacceptable in practice, they appear common. Determinants of poor practice relate to academic status and power, fuelled by institutional norms and culture. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

A shortfall exists of female doctors in senior academic posts in the United Kingdom. Career progression depends on measures of esteem, including publication in prestigious journals. This study investigates gender differences in first and senior authorship in six peer-reviewed British journals and factors that are associated with publication rates. Data was collected on United Kingdom first and senior authors who had published in the British Medical Journal, Lancet, British Journal of Surgery, Gut, British Journal of Obstetrics and Gynaecology and the Archives of Diseases in Childhood. Authorship and gender were quantified for 1970, 1980, 1990, 2000 and 2004 (n=6457). In addition, selected questions from the Athena Survey of Science Engineering and Technology (ASSET2006), web-based doctor's self-report of publications were also analysed (n=1162). Female first authors increased from 10.5% in 1970 to 36.5% in 2004 (p<0.001) while female senior authors only increased from 12.3% to 16.5% (p=0.046). Within individual journals, the largest rise was in British Journal of Obstetric and Gynaecology with 4.5- and 3-fold increases for first and senior authors, respectively. In contrast, female senior authors marginally declined in Gut and Lancet by 2.8% and 2.2%, respectively. ASSET2006 identified that female respondents who were parents were less likely to have publications as sole (p=0.02) and joint authors (p<0.001) compared to male respondents. Female respondents with care responsibilities for parents/partner also had less publications as lead authors compared to those without carer responsibilities (p<0.001). The increase in UK female first authors is encouraging. In contrast, there is considerable lag and in some specialties a decline in female senior authors. Factors that could narrow the gender gap in authorship should be sought and addressed.

There is a clear gender gap in scientific authorship. Although the proportions of female authors in medicine and psychiatry have increased over the past decades, women are still underrepresented. Aims To analyse authorship gender trends in eating disorder research. First and last author gender in research articles on eating disorders during the period 1997-2016 were assessed in eating disorder specialty journals, high-impact psychiatry journals and high-impact clinical psychology journals. The total number of papers on eating disorders increased substantially over the observation period, although a decrease was observed in high-impact psychiatry journals. Female authorship increased in both specialty journals and high-impact psychiatry journals. Authors were significantly less likely to be female in high-impact psychiatry and clinical psychology journals than in speciality journals. Eating disorder research has been increasingly allocated to specialty journals over the past 20 years. A consistent gender gap between specialty and high-impact journals exists.

Research on social processes in the production of scientific output suggests that the collective research agenda of a discipline is influenced by its structural features, such as "invisible colleges" or "groups of collaborators" as well as academic "stars" that are embedded in, or connect, these research groups. Based on an encompassing dataset that takes into account multiple publication types including journals and chapters in edited volumes, we analyze the complete co-authorship network of all 1,339 researchers in German political science. Through the use of consensus graph clustering techniques and descriptive centrality measures, we identify the ten largest research clusters, their research topics, and the most central researchers who act as bridges and connect these clusters. We also aggregate the findings at the level of research organizations and consider the inter-university co-authorship network. The findings indicate that German political science is structured by multiple overlapping research clusters with a dominance of the subfields of international relations, comparative politics and political sociology. A small set of well-connected universities takes leading roles in these informal research groups.

For scientists, authorship is academic currency. Authorship characteristics have been studied in a subset of the surgical and medical literature, but trends in the specialty of hand surgery have not yet been investigated. Specifically, a longitudinal analysis of number, educational training, sex, and geographical origin of authors has not been conducted. We explored the progression of authorship of scientific articles in a leading hand surgery journal. We recorded number of authors, number of references, degrees, and sex of the first and senior authors as well as geographical origin of the corresponding author in The Journal of Hand Surgery in 1985, 1995, 2005, and 2015. All original work was analyzed. A total of 892 articles were reviewed. The mean number of authors per article increased significantly from 2.6 in 1985 to 3.9 in 2015 and the number of references increased significantly from 13.7 in 1985 to 22.6 in 2015. There was a significant increase in the proportion of first authors with an MD/PhD, PhD, master's or bachelor's degree since 1985. During that same time period, a decrease in the proportion of first authors who held solely an MD was seen. There was a significant increase in proportion of the number of last authors with an MD/PhD, PhD or Master's degree in that same time period. There has been significant growth in publications originating from the "Far East" and "Other" regions, with 4.2% and 5.0% of publications, respectively, in 1985 having increased to 10.3% and 7.4% of publications, respectively, in 2015. Female first authorship significantly increased over the study period from 7.9% in 1985 to 22.1% of publications in 2015. There has been a significant increase in number of authors per article in The Journal of Hand Surgery. Similar to other studies, we noted shifts in the degrees most commonly held by authors, an increase in references per article, and a greater representation of international authors in the hand surgery. In addition, the

In academia, authorship is considered a currency and is important for career advancement. As the Journal of Bone and Mineral Research (JBMR) is the highest-ranked journal in the field of bone, muscle, and mineral metabolism and is the official publication of the American Society for Bone and Mineral Research, we sought to examine authorship changes over JBMR's 30-year history. Two bibliometric methods were used to collect the data. The "decade method" included all published manuscripts throughout 1 year in each decade over the past 30 years starting with the inaugural year, yielding 746 manuscripts for analysis. The "random method" examined 10% of published manuscripts from each of the 30 years, yielding 652 manuscripts for analysis. Using both methods, the average number of authors per manuscript, numerical location of the corresponding author, number of collaborating institutions, number of collaborating countries, number of printed manuscript pages, and the number of times each manuscript was cited all significantly increased between 1986 and 2015 (p authorship trends over the past 30 years and demonstrate those countries having the most changes and where challenges still exist. © 2017 American Society for Bone and Mineral Research. © 2017 American Society for Bone and Mineral Research.

2003-11-01

Scientific analysis of the linguistic styles of different authors has generated considerable interest. We present a generic approach to measuring the similarity of two symbolic sequences that requires minimal background knowledge about a given human language. Our analysis is based on word rank order-frequency statistics and phylogenetic tree construction. We demonstrate the applicability of this method to historic authorship questions related to the classic Chinese novel “The Dream of the Red Chamber,” to the plays of William Shakespeare, and to the Federalist papers. This method may also provide a simple approach to other large databases based on their information content.

Patterns of authorship in the IPCC Working Group III report

Corbera, Esteve; Calvet-Mir, Laura; Hughes, Hannah; Paterson, Matthew

2016-01-01

The Intergovernmental Panel on Climate Change (IPCC) has completed its Fifth Assessment Report (AR5). Here, we explore the social scientific networks informing Working Group III (WGIII) assessment of mitigation for the AR5. Identifying authors’ institutional pathways, we highlight the persistence and extent of North-South inequalities in the authorship of the report, revealing the dominance of US and UK institutions as training sites for WGIII authors. Examining patterns of co-authorship between WGIII authors, we identify the unevenness in co-authoring relations, with a small number of authors co-writing regularly and indicative of an epistemic community’s influence over the IPCC’s definition of mitigation. These co-authoring networks follow regional patterns, with significant EU-BRICS collaboration and authors from the US relatively insular. From a disciplinary perspective, economists, engineers, physicists and natural scientists remain central to the process, with insignificant participation of scholars from the humanities. The shared training and career paths made apparent through our analysis suggest that the idea that broader geographic participation may lead to a wider range of viewpoints and cultural understandings of climate change mitigation may not be as sound as previously thought.

Plagiarism, Intertextuality and Emergent Authorship in University Students' Academic Writing

Directory of Open Access Journals (Sweden)

Celia Helen Thompson

2009-08-01

Full Text Available Issues of plagiarism, intertextuality and authorial presence in academic writing are fundamental to the teaching and learning activities of all university lecturers and their students. Knowing how to assist students, particularly those who speak English as an additional language (EAL, to develop a sense of text/knowledge ownership and authorial presence in the creation of discipline-based scholarly texts can be especially challenging. Clarifying what is encompassed by the notion of ‘common knowledge’ is also central to this process. The aim of this paper is to explore the political and intertextual nature of text/knowledge construction and emergent student authorship through the analysis of interviews and written assignments from two EAL students, together with interview data from lecturers from relevant disciplinary fields. Drawing on the work of Bakhtin, Kristeva and Penrose and Geisler, I conclude by suggesting that it is by engaging with, rather than fearing, intertextual connections, that we can create a dialogic pedagogy for academic writing that will enable students to articulate an authoritative authorial identity of their own. The importance of lecturer intervention during the drafting stages of text production is also emphasised. Keywords: plagiarism; intertextuality; emergent authorship; academic writing

The strength of co-authorship in gene name disambiguation

Directory of Open Access Journals (Sweden)

Farkas Richárd

2008-01-01

Full Text Available Abstract Background A biomedical entity mention in articles and other free texts is often ambiguous. For example, 13% of the gene names (aliases might refer to more than one gene. The task of Gene Symbol Disambiguation (GSD – a special case of Word Sense Disambiguation (WSD – is to assign a unique gene identifier for all identified gene name aliases in biology-related articles. Supervised and unsupervised machine learning WSD techniques have been applied in the biomedical field with promising results. We examine here the utilisation potential of the fact – one of the special features of biological articles – that the authors of the documents are known through graph-based semi-supervised methods for the GSD task. Results Our key hypothesis is that a biologist refers to each particular gene by a fixed gene alias and this holds for the co-authors as well. To make use of the co-authorship information we decided to build the inverse co-author graph on MedLine abstracts. The nodes of the inverse co-author graph are articles and there is an edge between two nodes if and only if the two articles have a mutual author. We introduce here two methods using distances (based on the graph of abstracts for the GSD task. We found that a disambiguation decision can be made in 85% of cases with an extremely high (99.5% precision rate just by using information obtained from the inverse co-author graph. We incorporated the co-authorship information into two GSD systems in order to attain full coverage and in experiments our procedure achieved precision of 94.3%, 98.85%, 96.05% and 99.63% on the human, mouse, fly and yeast GSD evaluation sets, respectively. Conclusion Based on the promising results obtained so far we suggest that the co-authorship information and the circumstances of the articles' release (like the title of the journal, the year of publication can be a crucial building block of any sophisticated similarity measure among biological articles

News Authorship and News Sources: Impacts on Environmental Coverage in The Nigerian Press

Directory of Open Access Journals (Sweden)

Ogadimma C. Emenyeonu

2017-07-01

Full Text Available This study examines the impacts of news authorship and news sources on environmental coverage in the Nigerian press to shed light on the roles they play in news construction. The study finds that journalists in conjunction with policy makers are the catalyst for environmental information, whereas citizens who are pivotal in creating relevant public opinion on environmental issues are left behind. The study reveals that investigative reporting lacks in environmental coverage because most coverage are events driven which explains why environmental news is reported as straight news and as such journalists rely heavily on official sources rather than subsidiary sources. The study opines that for proper environmental coverage, journalists must choose sources from both main and subsidiary actors and revert to proactive, investigative and interpretive reporting so as to make environmental stories relatable to the intended audiences.

A bibliometric analysis. The aim of this article was to study bibliometric changes over the last 30 years of Spine. These trends are important regarding academic publication productivity. Inflation in authorship number and other bibliometric variables has been described in the scientific literature. The issue of author gender is taking on increasing importance, as efforts are being made to close the gender gap. From 1985 to 2015, 10-year incremental data for several bibliometric variables were collected, including author gender. Standard bivariate statistical analyses were performed. Trends over time were assessed by the Cochran linear trend. A P < 0.05 was considered statistically significant. Inclusion criteria were met for 1566 manuscripts. The majority of the manuscripts were from North America (51.2%), Europe (25.2%), and Asia (20.8%). The number of manuscripts, authors, countries, pages, and references all increased from 1985 to 2015. There was a slight increase in female first authors over time (17.5% to 18.4%, P = 0.048). There was no gender change over time for corresponding authors (14.3% to 14.0%, P = 0.29). There was an 88% increase in the percentage of female first authors having male corresponding authors (P = 0.00004), and a 123% increase in male first authors having female corresponding authors (P = 0.0002). The 14% to 18% of female authors in Spine is higher than the ∼5% female membership of the Scoliosis Research Society and North American Spine Society. Manuscripts in Spine over the past 30 years have shown a significant increase in the number of authors, collaborating institutions and countries, printed pages, references, and number of times each manuscript was cited. There has been a mild increase in female first authorship, but none in corresponding authorship. Increases in female authorship will likely require recruitment of more females into the discipline rather than providing females in the discipline with authorship

Unmerited authorship is a practice common to many countries around the world, but are there systematic cultural differences in the practice? We tested whether scientists from collectivistic countries are more likely to add unmerited coauthors than scientists from individualistic countries. We analyzed archival data from top scientific journals (Study 1) and found that national collectivism predicted the number of authors, which might suggest more unmerited authors. Next, we found that collect...

The scientific authorship of Doctor Chernoviz, from the popularization of medicine to professional training: the Dicionário de medicina popular, 1842-1890.

Science.gov (United States)

Medeiros, Aline da Silva

2018-03-01

This article reflects on the scientific authorship of Pedro Luiz Napoleão Chernoviz, based on his Dicionário de medicina popular, which was published in six editions between 1842 and 1890. The first part of the text discusses Chernoviz's position within the regimes of scientific authorship which were present in the medical community in Rio de Janeiro. Next, we analyze the author's arguments justifying a text that popularized medical science while this field strove for exclusivity in the practice of medicine. Finally, we suggest new meanings around Chernoviz's scientific authorship based on how the Dicionário was used and read by an initiated public.

Blogs, Twitter Feeds, and Reddit Comments: Cross-domain Authorship Attribution

Overdorf Rebekah

2016-07-01

Full Text Available Stylometry is a form of authorship attribution that relies on the linguistic information to attribute documents of unknown authorship based on the writing styles of a suspect set of authors. This paper focuses on the cross-domain subproblem where the known and suspect documents differ in the setting in which they were created. Three distinct domains, Twitter feeds, blog entries, and Reddit comments, are explored in this work. We determine that state-of-the-art methods in stylometry do not perform as well in cross-domain situations (34.3% accuracy as they do in in-domain situations (83.5% accuracy and propose methods that improve performance in the cross-domain setting with both feature and classification level techniques which can increase accuracy to up to 70%. In addition to testing these approaches on a large real world dataset, we also examine real world adversarial cases where an author is actively attempting to hide their identity. Being able to identify authors across domains facilitates linking identities across the Internet making this a key security and privacy concern; users can take other measures to ensure their anonymity, but due to their unique writing style, they may not be as anonymous as they believe.

Authorship and authenticity in Sherlock Holmes pastiches

Directory of Open Access Journals (Sweden)

Sanna Nyqvist

2017-03-01

Full Text Available Rewritings and adaptations of the Sherlock Holmes stories are traditionally called pastiches among fandom. This article juxtaposes that established use with the literary critical notion of pastiche as imitation of style, and shows how stylistic affinity to the originals produces complex effects in the imitations. The article identifies two main strands in the pastiches: one that aims to correct the mistakes and fill in the gaps in the original stories, and one that supplements the canon with stories Watson left untold. Balancing among homage, criticism, and usurpation, the pastiches comment on the original story world and its cultural context, and engage in fictions of authorship to account for the apparent inauthenticity of the retellings.

Authorship Guidelines and Actual Practice: Are They Harmonized in Different Research Systems?

Directory of Open Access Journals (Sweden)

Sonia Vasconcelos

2014-10-01

Full Text Available Changing patterns in collaborative research networks reflect a new geography of science that is increasingly shaped by interactions between established and emerging scientific powers, whose cultural and political diversity are now reflected in perhaps never before thought of interactions. The various partners in these international collaborations are likely to produce research results that should gradually lead to stronger diversity in research output, including an increase in international co-authorship. When it comes to multinational co-authored publications, among sensitive questions that may complicate these relationships is the way different research systems deal with research integrity. It is well worth examining how to accommodate different cultural traditions and normative assumptions embedded in academic practices for collaborative research networks. Given the increasingly international and interdisciplinary nature of science and engineering, any guidelines for authorship practices in international collaborations must be clear about the variations that exist across disciplines and cultures, variations which will have an impact on accepted practices and expectations for collaboration. Collaborative endeavors in research will succeed only if a broader understanding of potential obstacles to these collaborations is reached.

Attributing Authorship in the Noisy Digitized Correspondence of Jacob and Wilhelm Grimm

Greta Franzini

2018-04-01

Full Text Available This article presents the results of a multidisciplinary project aimed at better understanding the impact of different digitization strategies in computational text analysis. More specifically, it describes an effort to automatically discern the authorship of Jacob and Wilhelm Grimm in a body of uncorrected correspondence processed by HTR (Handwritten Text Recognition and OCR (Optical Character Recognition, reporting on the effect this noise has on the analyses necessary to computationally identify the different writing style of the two brothers. In summary, our findings show that OCR digitization serves as a reliable proxy for the more painstaking process of manual digitization, at least when it comes to authorship attribution. Our results suggest that attribution is viable even when using training and test sets from different digitization pipelines. With regards to HTR, this research demonstrates that even though automated transcription significantly increases the risk of text misclassification when compared to OCR, a cleanliness above ≈ 20% is already sufficient to achieve a higher-than-chance probability of correct binary attribution.

Experimental Investigation of Principal Residual Stress and Fatigue Performance for Turned Nickel-Based Superalloy Inconel 718.

2018-05-24

Residual stresses of turned Inconel 718 surface along its axial and circumferential directions affect the fatigue performance of machined components. However, it has not been clear that the axial and circumferential directions are the principle residual stress direction. The direction of the maximum principal residual stress is crucial for the machined component service life. The present work aims to focuses on determining the direction and magnitude of principal residual stress and investigating its influence on fatigue performance of turned Inconel 718. The turning experimental results show that the principal residual stress magnitude is much higher than surface residual stress. In addition, both the principal residual stress and surface residual stress increase significantly as the feed rate increases. The fatigue test results show that the direction of the maximum principal residual stress increased by 7.4%, while the fatigue life decreased by 39.4%. The maximum principal residual stress magnitude diminished by 17.9%, whereas the fatigue life increased by 83.6%. The maximum principal residual stress has a preponderant influence on fatigue performance as compared to the surface residual stress. The maximum principal residual stress can be considered as a prime indicator for evaluation of the residual stress influence on fatigue performance of turned Inconel 718.

Full Text Available Residual stresses of turned Inconel 718 surface along its axial and circumferential directions affect the fatigue performance of machined components. However, it has not been clear that the axial and circumferential directions are the principle residual stress direction. The direction of the maximum principal residual stress is crucial for the machined component service life.

Full Text Available Information technology has given rise to the problem of controlling the use of copyrighted works of authorship from their unauthorized use. In this context, one of the effective solutions is the application of technological protection measures, which are aimed at a more efficient application of the protection measures prescribed by the law. Technological protection measures imply the use of any technology, device or component which may be aimed at preventing or restricting an unauthorized use of a protected work of authorship, which has not been approved by the author or holder of some related right. Generally, all these measures may be classified into three basic groups: technological measures aimed at controlling access, technological measured aimed at controlling exploitation, and technological measures aimed at protecting the integrity of the work of authorship. Considering their technical characteristics and mode of application, they may be hardware-based measures, software-based measures, or a combination thereof. Modern technology has enabled the development of digital systems which entail a controlled use of copyrighted works and facilitate obtaining licences for their exploitation. They are commonly known as digital rights management (DRM. The DRM system should provide for a compromise between safeguarding the intellectual property rights of the copyright holder, the end user privacy, and system costs. The envisaged goals are achieved by employing various cryptographic measures. The process of developing technological protection measures is accompanied by concurrent attempts to circumvent the application of these measures. Thus, the effectiveness of these measures primarily depends on their legal protection, which has been recognized by a vast majority of legal systems, we now know the most modern legal system. However, the normative solutions are not uniform. The observed differences actually reflect problems in finding adequate forms

Trends and Developments in Multi-Authorship in five Social Science disciplines from 1991 to 2014

Energy Technology Data Exchange (ETDEWEB)

Mayer, S.J

2016-07-01

This article explores developments in author numbers in five disciplines of the Social Sciences from 1991 to 2014, Economics, Educational Sciences, Political Science, Psychology, and Sociology. The relationship between the mean number of authors per article (in every discipline's five top journals) and three factors, publication year, international collaboration (IC), and article content (theoretical, experimental, or large-scale comparative) are analyzed. The findings show that single-authorship is decreasing and multi-authorship is on the rise, publication year was found to be significantly correlated with the number of authors. In addition, IC is positively correlated with the number of authors, even when publication year is controlled for. The content type “theoretical articles” is negatively related to the number of authors, even when publication year is controlled for. (Author)

The Gender of Authorship: Heiner Müller and Christa Wolf

OpenAIRE

Helen Fehervary

1980-01-01

The relationship between sexuality and politics has always been an underlying assumption of the avant-garde. In recent East German avant-garde literature, the notion of authorship as production has become associated with technological rationality and the patriarchal socialist state. The ensuing crisis of the traditional male author has thus led necessarily to a radicalization of subjectivity and to the politics of gender. A comparison of two contemporary texts, one by a female author, one by ...

Gender Differences in the Authorship of Original Research in Pediatric Journals, 2001-2016.

Fishman, Michael; Williams, Wadsworth A; Goodman, Denise M; Ross, Lainie Friedman

2017-12-01

To examine the gender of authors of original research in 3 high-impact pediatric journals between 2001 and 2016, given the importance of publishing on academic promotion, and to compare authorship gender with the percentage of women on editorial boards and with academic faculty composition. We assessed the prevalence of female first and senior (last-listed) authorship of original research articles published in 3 pediatric-focused journals Pediatrics, JAMA Pediatrics (entitled Archives of Pediatric and Adolescent Medicine until 2013), and The Journal of Pediatrics. We also examined the gender breakdown of the main editors and the broader editorial boards of these journals. In addition, we examined whether junior female faculty co-authored with male or female senior faculty. Of 3895 original articles, 22 were excluded because the gender of either the first or senior author could not be determined from the name. An analysis of authorship by year showed increasing female representation across the selected journals in both first (39.8% in 2001, 57.7% in 2016) and senior (28.6% in 2001, 38.1% in 2016) authors, respectively. Editorial boards also showed increasing female representation (17.8% in 2001 to 39.8% in 2016). Junior female faculty were more likely to co-author with senior female women (female first and last author); the gap remained unchanged despite the increasing number of women entering pediatrics. Women are underrepresented as authors and editors, although the gap is closing. Junior women are less likely to co-author with senior men, which may be a disservice given current gender disparities in promotion and leadership. Copyright © 2017 Elsevier Inc. All rights reserved.

Unfinalisability and the authorship of life - Narratives of young-old women from Taiwan.

Science.gov (United States)

Kok, Jin Kuan; Li, Ming-Chin

2017-08-01

This study investigates and presents the narratives of Taiwanese women who have reached the young-old stage. The narrative interview method was used for data collection from 12 Taiwanese women. After analysing the recurring themes emerging from the women's life histories, it is found that the meanings of these Taiwanese women's narratives could not be finalised according to traditional Confucian norms. These women rebelled, resisted, and resumed authorship to make changes to their lives in a patriarchal society. The women were reflexive, and had constant struggles. The findings also reveal a prominent characteristic of Taiwanese culture that emphasises relationships. The women were able to pursue their dreams to involve themselves in self-care, leisure, aesthetic activities, and classes for their personal growth and pleasure. Copyright © 2017 Elsevier Inc.

The literary science as de-facement. Problem of double authorship in Tadeusz Rachwał and Tadeusz Sławek's texts

Directory of Open Access Journals (Sweden)

Piotr Bogalecki

2007-11-01

Full Text Available The essay is an attempt of rethinking a mode of authorship in literary science discourse of Tadeusz Rachwał and Tadeusz Sławek. Their texts is being compared with G. Deleuze and F. Guattari's method of collective writing and interpreted according to theories of J. Derrida, P. de Man and M. Foucault. Rachwał and Sławek's strategy of double authorship (which is not the same as traditional co-authorship underlines the impossibility of recognition who is speaking in the text; therefore their collective books may be understood as a kind of performing theses which they contain (e.g. connected with poststructuralist "death of author" or a poet and God's mystical co-writing. Furthermore, double authorship leaves its marks on structure of text. We can see a lot of techniques which make Rachwał and Sławek's texts more complicated, e.g. fragmentary style of writing, using different types of typography and even creating an elements of visual poetry. These experiments and a new way of these texts' being in academic public sphere make them rather ethical than scientific - the ethic qualities and poetic function seem to be more important than the science typical cognitive functions. Because of unceasing underlining a linguistic aspect, the texts of Rachwał and Sławek may be read as examples of rhetorical type of ethic criticism. Not only do they ask about a significance of primary ethical ideas like friendship, community or responsibility, but also about an existence of category of author in literary studies after linguistic turn.

The role of gender in scholarly authorship.

Jevin D West

Full Text Available Gender disparities appear to be decreasing in academia according to a number of metrics, such as grant funding, hiring, acceptance at scholarly journals, and productivity, and it might be tempting to think that gender inequity will soon be a problem of the past. However, a large-scale analysis based on over eight million papers across the natural sciences, social sciences, and humanities reveals a number of understated and persistent ways in which gender inequities remain. For instance, even where raw publication counts seem to be equal between genders, close inspection reveals that, in certain fields, men predominate in the prestigious first and last author positions. Moreover, women are significantly underrepresented as authors of single-authored papers. Academics should be aware of the subtle ways that gender disparities can occur in scholarly authorship.

Directory of Open Access Journals (Sweden)

Rajesh Gyawali

2017-01-01

Full Text Available Objective: To explore the demographic features of the articles published in South Asian orthodontic journals in the last 6 years. Materials and Methods: All the orthodontic journals published from or representing South Asian countries from 2011 to 2016 were analyzed for the number of issues published, number of articles, number of authors, country affiliation of principal author, and international collaboration in authorship. Further, article type was classified and number of citations was noted. Descriptive statistics was used to characterize the various features of the published articles. Results: A total of 825 articles were found in five orthodontic journals published from or representing South Asian region with the number authors per article ranging up to 10. International collaboration in authorship varied from 0.98% to 12.75% of articles among those journals. For all journals, principal authors of most of the articles originated from the country of publishing journal. Cross-sectional study overnumbered other types of researches. However, systematic reviews and meta-analysis which are considered as the highest form of evidence were very scant in these journals. Conclusions: International collaboration in authorship and foreign principal investigator was found minimum. Greater percentage of publications were cross-sectional studies with few randomized controlled trials and systematic reviews/meta-analysis in the last 6 years.

This research is a descriptive-survey method and in terms purpose is practical. The statistical population of this study consisted of principals of the primary schools in Pakdasht city. The total number of primary school principals in this city is 135 people (75 male schools and 60 female schools. As data gathering tool, a researcher-made questionnaire was used. In order to analyze the validity of the questionnaire in this study, the Content Validation Method was used in which the questionnaires were first examined by the experts and the necessary corrections were made. The reliability of the questionnaire was evaluated using Cronbach's alpha coefficient. Research hypotheses were tested using structural equation modeling and AMOS software. The results show that competence and effectiveness aspects affect competence and success of principals of the Pakdasht elementary schools. Autonomy affects the competence level of elementary school principals in Pakdasht city but does not affect principals' success. Meaningfulness aspect did not affect principals’ competency however it is effective on principals’ success in Pakdasht elementary schools. Trust aspect was not effective on the Pakdasht elementary schools principals’ competence and success.

Research leadership and investigators: gender distribution in the federal government.

McCarren, Madeline; Goldman, Steven

2012-08-01

The National Academies reported in Beyond Bias and Barriers: Fulfilling the Potential of Women in Academic Science and Engineering (2006) that "women are very likely to face discrimination." In academic medicine, gender distribution is becoming more balanced. In the federal government, women also have made progress, doubling their representation in professional positions to 44%. The Department of Veterans Affairs (VA) has a research program and a mission to train health care professionals; however, its gender distribution has not been described. We conducted a descriptive study using public data for positions in the VA, National Institutes of Health (NIH), and Agency for Healthcare Research and Quality (AHRQ). We followed with a case-control analysis of predictors of receipt of grant funding in the VA. Participants were 224 leadership positions and 132 principal investigators. Women comprised 33% (AHRQ), 27% (NIH), and 0% (VA) of the top research leadership. Across all VA research levels, women comprised 45% to 0%, depending on the service. In the case-control analysis of principal investigators, men had greater odds (odds ratio 8.0) of a Cooperative Studies Program (CSP) trial award. History of first, last, or any authorship on a clinical trial publication in the 10 years before the index trial was only weakly associated with award of a CSP trial. The gender imbalance was not explained by publication history. Marked gender disparities were seen in the VA, except in Health Services Research. Organizations must investigate their practices to reveal disparities, investigate underlying factors, and intervene as needed. Published by Elsevier Inc.

The aim of this study was to evaluate the evolution of women authorship in France and to analyze the recent trends of the evolution of gender differences in French academic radiology. A retrospective bibliometric analysis was performed by searching for articles published in Diagnostic and Interventional Imaging (Diagn Interv Imaging) and in Journal de Radiologie (J Radiol) in Pubmed over the last three decades. For each of these articles, we determined the gender of the first and last author. The specific radiological field of each article was also determined. The proportion of women authors has significantly increased from 12% in 1984 to 34% in 2014 (Pauthorship in Diagnostic and Interventional Imaging has increased over the last years together with the proportion of women first authors. However, the fraction of women last authors is still underrepresented. More women need to become leaders in radiological research to contribute to stimulate women authorship.

Data mining of text as a tool in authorship attribution

Science.gov (United States)

Visa, Ari J. E.; Toivonen, Jarmo; Autio, Sami; Maekinen, Jarno; Back, Barbro; Vanharanta, Hannu

2001-03-01

It is common that text documents are characterized and classified by keywords that the authors use to give them. Visa et al. have developed a new methodology based on prototype matching. The prototype is an interesting document or a part of an extracted, interesting text. This prototype is matched with the document database of the monitored document flow. The new methodology is capable of extracting the meaning of the document in a certain degree. Our claim is that the new methodology is also capable of authenticating the authorship. To verify this claim two tests were designed. The test hypothesis was that the words and the word order in the sentences could authenticate the author. In the first test three authors were selected. The selected authors were William Shakespeare, Edgar Allan Poe, and George Bernard Shaw. Three texts from each author were examined. Every text was one by one used as a prototype. The two nearest matches with the prototype were noted. The second test uses the Reuters-21578 financial news database. A group of 25 short financial news reports from five different authors are examined. Our new methodology and the interesting results from the two tests are reported in this paper. In the first test, for Shakespeare and for Poe all cases were successful. For Shaw one text was confused with Poe. In the second test the Reuters-21578 financial news were identified by the author relatively well. The resolution is that our text mining methodology seems to be capable of authorship attribution.

On authorship in Samuel Beckett’s prose

Directory of Open Access Journals (Sweden)

Willian André

2014-06-01

Full Text Available This study aims at building a reflection on the notion of authorship in Samuel Beckett’s work, with a main focus on his short prose from the 60s and 70s. Thereunto, supported by the writings of Maurice Blanchot, S. E. Gontarski, João Adolfo Hansen and Hugh Kenner, we draw a route that starts with the Beckettian post-war trilogy, going through the subsequent productions that culminate in the short pieces outlined by the author after the publishing of How It Is (1961. As we take the path run by the Irish writer in his deal with failure (a path full of mud and light-grey-dark oscillations, we experience the rise of a paradoxical impression: the more severe are Beckett’s attacks against the shapes of the I, testifying the dilution of identity, more accurate become the shapes surrounding the idea of “author” that surmounts the whole of his literary project.

Quantitative Study of the Geographical Distribution of the Authorship of High-Energy Physics Journals

CERN Document Server

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.

Yun, Eun Joo; Yoon, Dae Young; Kim, Bitna; Moon, Ji Yoon; Yoon, Soo Jeong; Hong, Su Jin; Baek, Sora

2015-08-01

The purpose of this study was to evaluate gender differences in the authorship of original research articles by radiologists in two major American radiology journals, AJR and Radiology. In a retrospective bibliometric analysis, all original articles published in AJR and Radiology during three 3-year periods (1991-1993, 2001-2003, and 2011-2013) were reviewed to determine the gender of the first and corresponding radiology authors. In addition, radiologic subspecialty and country of the authors were also abstracted from each article. The gender of the first and corresponding authors could be determined for 10,043 of 10,228 authors (98.2%) of original research in radiology. Between the periods 1991-1993 and 2011-2013, the percentage of female authors significantly increased: from 20.4% to 34.4%, respectively, among first authors (p < 0.0001); and from 18.0% to 28.7%, respectively, among corresponding authors (p < 0.0001). There was a significant correlation between the gender of the first and corresponding authors (p < 0.05). In the 2011-2013 period, the proportion of female authors was highest in breast (64.2%) and pediatric (48.2%) and lowest in vascular and interventional (18.5%) and cardiac (21.0%) subspecialties. The proportion of female authors was the highest in The Netherlands (47.3%), South Korea (37.9%), France (36.2%), and Italy (33.6%). There was a significant increase in the female authorship of original research articles in two major American radiology journals between the periods 1991-1993 and 2011-2013.

Full Text Available Here we present the first empirical evidence to support the hypothesis that a gender-heterogeneous problem-solving team generally produced journal articles perceived to be higher quality by peers than a team comprised of highly-performing individuals of the same gender. Although women were historically underrepresented as principal investigators of working groups, their frequency as PIs at the National Center for Ecological Analysis and Synthesis is now comparable to the national frequencies in biology and they are now equally qualified, in terms of their impact on the accumulation of ecological knowledge (as measured by the h-index. While women continue to be underrepresented as working group participants, peer-reviewed publications with gender-heterogeneous authorship teams received 34% more citations than publications produced by gender-uniform authorship teams. This suggests that peers citing these publications perceive publications that also happen to have gender-heterogeneous authorship teams as higher quality than publications with gender uniform authorship teams. Promoting diversity not only promotes representation and fairness but may lead to higher quality science.

Database Documentary: From Authorship to Authoring in Remediated/Remixed Documentary

Directory of Open Access Journals (Sweden)

Hart Cohen

2012-06-01

Full Text Available The engagement with documentary from its inception as a film form is frequently a set of references to documentary auteurs. The names of Flaherty, Grierson, Vertov and later Ivens, Leacock and Rouch are immediate signifiers of whole documentary film practices. These practices have given rise to histories and criticism that have dominated discussion of documentary and provided the foundation for more nuanced thinking about problems of the genre. One of the seminal texts in the field, Documentary by Erik Barnouw (1974 celebrates the auteur as the structuring principle for his historical review of documentary. It may be a reflection of the influence of this book, that so much of documentary criticism reflects the auteur approach as a starting point for analysis. The shift towards a new documentary format, the Database Documentary, challenges the concept of an auteur in its presentation of documentary materials. This format relies on a remediation technique that recalibrates documentary media within new distributive networks supported by the web and enhanced by converged and designed visual and sonic interfaces. The reception modalities are necessarily removed from the familiar forms of projection and presentation of documentary film and television. The research focus for this paper is how the concept of authorship (the “auteur” is transformed by the emergence of the relatively new screen format of the database documentary. The paper reviews some of the more recent examples of Database Documentary, the contexts for their production and the literature on new conceptions of documentary knowledge that may be drawn from these examples. An analysis of the authoring program, Korsakow and the documentaries that have been made using its software will demonstrate the route documentary has travelled from authorship to authoring in contemporary media production.

2014-05-01

Biomedical research has grown considerably in the last few decades, and the authorship characteristics of the dental literature as a whole and of its specialty fields has changed significantly. Unfortunately, the bibliometrics of the periodontal literature have not been thoroughly investigated. The aim of this study is to investigate the bibliometrics of periodontal literature, assessing the geographic origin, study design, and topics investigated in periodontal research published from 1995 to 2010. Articles published in periodontal journals during 1995 to 2010 were retrieved through hand search. Inclusion/exclusion criteria were applied. The following variables were extrapolated from each article: number of authors, study design, topic investigated, financial support, and geographic origin. The general linear model assessed the influence of independent variables on number of authors per article, and χ(2) test assessed the statistical difference of the variables over years 1995 to 2010. A total of 2,260 articles were reviewed; 2,076 met the inclusion criteria. The number of authors per article increased (P <0.001) from 4.0 (1995) to 5.1 (2010). The proportion of articles published from North America and Europe decreased (P <0.001) from 84.3% (1995) to 58.6% (2010), whereas for Asia and South America the article proportion increased (P <0.001) from 13.8% (1995) to 40% (2010). Research targeting prevention and treatment of periodontal disease is decreasing (P <0.001) in favor of implant-related research. Governmental research funding is increasing (P <0.001). Periodontal research significantly changed during the last 15 years.

The existence of a gender gap in academia has been a hotly debated topic over the past several decades. It has been argued that due to the gender gap, it is more difficult for women to obtain higher positions. Manuscripts serve as an important measurement of one's accomplishments within a particular field of academia. Here, we analyzed, over the past 3 decades, authorship and other trends in manuscripts published in BONE, one of the premier journals in the field of bone and mineral metabolism. For this study, one complete year of manuscripts was evaluated (e.g. 1985, 1995, 2005, 2015) for each decade. A bibliometric analysis was then performed of authorship trends for those manuscripts. Analyzed fields included: average number of authors per manuscript, numerical position of the corresponding author, number of institutions collaborating on each manuscript, number of countries involved with each manuscript, number of references, and number of citations per manuscript. Each of these fields increased significantly over the 30-year time frame (pgender of both the first and corresponding authors was identified and analyzed over time and by region. There was a significant increase in the percentage of female first authors from 23.4% in 1985 to 47.8% in 2015 (p=0.001). The percentage of female corresponding authors also increased from 21.2% in 1985 to 35.4% in 2015 although it was not significant (p=0.07). With such a substantial emphasis being placed on publishing in academic medicine, it is crucial to comprehend the changes in publishing characteristics over time and geographical region. These findings highlight authorship trends in BONE over time as well as by region. Importantly, these findings also highlight where challenges still exist. Copyright © 2017 Elsevier Inc.

Mine, thine, and ours: collaboration and co-authorship in the material culture of the mid-twentieth century chemical laboratory.

Science.gov (United States)

Nye, Mary Jo

2014-08-01

Patterns of collaboration and co-authorship in chemical science from the 1920s to the 1960s are examined with an eye to frequency of co-authorship and differences in allocation of credit during a period of increasing team research and specialization within chemical research groups. Three research leaders in the cross-disciplinary and cutting edge field of X-ray crystallography and molecular structure are the focus of this historical study within a framework of sociological literature on different collaborative patterns followed by eminent scientists. The examples of Michael Polanyi in Berlin and Manchester, Linus Pauling in Pasadena, and Dorothy Crowfoot Hodgkin in Oxford demonstrate the need to de-centre historical narrative from the heroic 'he' or 'she' to the collaborative 'they.' These cases demonstrate, too, the roles of disciplinary apprenticeships, local conditions, and individual personalities for historical explanation that transcends universal generalizations about scientific practice, material culture, and sociological trends.

Major gender differences exist in cardiovascular diseases and lead to different outcomes in women and men. However, attention and incorporation of sex-/gender-specific research might vary among disciplines. We therefore conducted a systematic review comparing publication characteristics and trends between stroke and myocardial infarction (MI) with respect to sex- and gender-related aspects. A systematic literature search was performed in PubMed to identify gender-/sex-related articles published for stroke and MI between 1977 and 2008. A specifically designed text mining program was used, and all literature was rated by two independent investigators. Publications were classified according to type of research performed, publication year, funding, geographical location, and gender of first and last authors. 962 articles were retrieved and limited to 405 (42%) gender-relevant publications; 131 on stroke and 274 on MI. Type of performed research differed, especially in disease management, which received little attention (17%) in stroke, while representing the major focus in MI (40%). In both areas, clinical presentation received little attention (3 and 5%). Although publications progressively increased in both fields, an 8- to 10-year time gap emerged for stroke compared to MI. Last authors in both areas were predominantly men, but female last authorship is increasing more significantly over time in the field of stroke. Research on sex and gender differences in MI and stroke is largely underfunded, particularly by the EU. The data demonstrate how sex-/gender-specific research differs between specialties, most likely due to the diverse interest, funding opportunities and authorship distributions identified.

Scientific authorships and collaboration network analysis on Chagas disease: papers indexed in PubMed (1940-2009).

Science.gov (United States)

González-Alcaide, Gregorio; Park, Jinseo; Huamaní, Charles; Gascón, Joaquín; Ramos, José Manuel

2012-08-01

Chagas disease is a chronic, tropical, parasitic disease, endemic throughout Latin America. The large-scale migration of populations has increased the geographic distribution of the disease and cases have been observed in many other countries around the world. To strengthen the critical mass of knowledge generated in different countries, it is essential to promote cooperative and translational research initiatives. We analyzed authorship of scientific documents on Chagas disease indexed in the Medline database from 1940 to 2009. Bibliometrics was used to analyze the evolution of collaboration patterns. A Social Network Analysis was carried out to identify the main research groups in the area by applying clustering methods. We then analyzed 13,989 papers produced by 21,350 authors. Collaboration among authors dramatically increased over the study period, reaching an average of 6.2 authors per paper in the last five-year period. Applying a threshold of collaboration of five or more papers signed in co-authorship, we identified 148 consolidated research groups made up of 1,750 authors. The Chagas disease network identified constitutes a "small world," characterized by a high degree of clustering and a notably high number of Brazilian researchers.

2011-01-01

This research aimed to analyze the patterns of co-authorship network among the Korean radiation oncologists and to identify attributing factors for the formation of networks. A total of 1,447 articles including contents of 'Radiation Oncology' and 'Therapeutic Radiology' were searched from the KoreaMed database. The co-authorship was assorted by the author's full name, affiliation and specialties. UCINET 6.0 was used to figure out the author's network centrality and the cluster analysis, and KeyPlayer 1.44 program was used to get a result of key player index. Sociogram was analyzed with the Netdraw 2.090. The statistical comparison was performed by a t-test and ANOVA using SPSS 16.0 with p-value < 0.05 as the significant value. The number of articles written by a radiation oncologist as the fi rst author was 1,025 out of 1,447. The pattern of coauthorship was classified into fi ve groups. For articles of which the fi rst author was a radiation oncologist, the number of single author articles (type-A) was 81; single-institution articles (type-B) was 687; and multiple-author articles (type-C) was 257. For the articles which radiation oncologists participated in as a co-author, the number of single-institution articles (type-D) was 280 while multiple-institution articles (type-E) were 142. There were 8,895 authors from 1,366 co-authored articles, thus the average number of authors per article was 6.51. It was 5.73 for type-B, 6.44 for type-C, 7.90 for type-D, and 7.67 for type-E (p 0.000) in the average number of authors per article. The number of authors for articles from the hospitals published more than 100 articles was 7.23 while form others was 5.94 (p = 0.005). Its number was 5.94 and 7.16 for the articles published before and after 2001 (p = 0.000). The articles written by a radiation oncologist as the fi rst author had 5.92 authors while others for 7.82 (p = 0.025). Its number was 5.57 and 7.71 for the Journal of the Korean Society for Therapeutic Radiology

A Narrative Approach to Authorship: The Work of Evi Tampold from Her Mother/Publisher’s (and Her Own Perspective

2017-12-01

Full Text Available Collaborative authorship in graphic medicine is examinable from a number of perspectives.  One neglected approach is to look for developments in how an individual artist collaborates over the course of illustrating different graphic medicine novels.  In the first, the artist collaborated with her younger self in trying to regain memories of an until then forgotten past.  In the second, she worked closely with the writer to try to determine exactly what the author intended, adding a new dimension to the piece unavailable without the illustrations.  In the third still to be completed work, her illustrations are based on collaboration with only the text and a few photographs, lacking direct contact with the author.  How this artist’s three methods of collaboration have defined her collaborative authorship will be the focus.  What is unique is this study will be undertaken from the stand point of the illustrator’s publisher, who is also her mother.

One and done: Reasons principal investigators conduct only one FDA-regulated drug trial

Directory of Open Access Journals (Sweden)

Amy Corneli, PhD, MPH

2017-06-01

Full Text Available Concerns have been raised over the high turnover rate for clinical investigators. Using the U.S. Food and Drug Administration's (FDA Bioresearch Monitoring Information System database, we conducted an online survey to identify factors that affect principal investigators' (PIs decisions to conduct only a single FDA-regulated drug trial. Of the 201 PIs who responded, 54.2% were classified as “one-and-done.” Among these investigators, 28.9% decided for personal reasons to not conduct another trial, and 44.4% were interested in conducting another trial, but no opportunities were available. Three categories of broad barriers were identified as generally burdensome or challenging by the majority of investigators: 1 workload balance (balancing trial implementation with other work obligations and opportunities (63.8%; 2 time requirements (time to initiate and implement trial; investigator and staff time (63.4%; and 3 data and safety reporting (56.5%. Additionally, 46.0% of investigators reported being generally unsatisfied with finance-related issues. These same top three barriers also affected investigators' decisions to no longer conduct FDA-regulated trials. Our findings illuminate three key aspects of investigator turnover. First, they confirm that investigator turnover occurs, as more than half of respondents were truly “one-and-done.” Second, because a large proportion of respondents wanted to conduct more FDA-regulated trials but lacked opportunities to do so, mechanisms that match interested investigators with research sponsors are needed. Third, by focusing on the barriers we identified that affected investigators' decisions to no longer conduct FDA-regulated trials, future efforts to reduce investigator turnover can target issues that matter the most to investigators.

Lessons from implementation of ecohealth projects in Southern Africa: A principal investigator's perspective.

Science.gov (United States)

Chimbari, Moses John

2017-11-01

Ecohealth projects are designed to garner ownership among all stakeholders, such as researchers, communities, local leadership and policy makers. Ideally, designs should ensure that implementation goes smoothly and that findings from studies benefit the stakeholders, particularly bringing changes to the communities researched. Paradoxically, the process is fraught with challenges associated with implementation. Notwithstanding these challenges, evidence from projects implemented in southern Africa justify the need to invest in the subject of ecohealth. This paper describes and discusses a principal investigator's experience of leading ecohealth projects in Zimbabwe between 2002 and 2005, in Botswana between 2010 and 2014 and in South Africa (ongoing). The discourse is centred on issues of project management and leadership, transdisciplinarity, students' involvement, data management, community engagement, dissemination of research findings and the role of institutions in project management and implementation. The paper concludes that the ecohealth approach is valuable and should be encouraged making the following recommendations; 1) principal investigators must have a good understanding of socio-ecological systems, have excellent project management and writing skills, 2) more than one PI should be involved in the day-to-day running of the project in order to avoid disruption of project activities in the event that the PI leaves the project before it ends, 3) researchers should be trained in ecohealth principles and methodologies at the time of building the research teams, 4) full proposals should be developed with active participation of communities and stakeholders in order to develop a shared vision, 5) involvement of postdoctoral fellows and dedicated researchers with postgraduate students should be encouraged to avoid situations where some objectives are not fully addressed because of the narrow nature of students' work; and 6) citizen science should be

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

Science.gov (United States)

Koniaris, Leonidas G; Coombs, Mary I; Meslin, Eric M; Zimmers, Teresa A

2016-08-01

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

Introduction: Breast cancer is one of the highest reasons of deaths for people in the world. The objective of current study is to analyze and visualize the trend of global scientific activities in the field of breast cancer during a period of 10 years through 2006-2015. Methods: The current study was performed by utilizing the scientometrics analysis and mapping the co-authorship and co-organization networks. The Web of Science Core Collection (WoS-CC)database was used to extract all papers indexed as a topic of breast cancer through 2006 to 2015. Research productivity was measured through analysis several parameters, including: the number and time course of publications, the journal and language of publications, the frequency and type of publications, as well as top 20 active sub-categories together with country contribution. The extracted data were transferred into the Excel charts and plotted as diagrams. The Science of Science (Sci2) and CiteSpace softwares were used as tools for mapping the co-authorship and co-organization networks of the published papers. Results: Analysis of data indicated that the number of publications in the field of breast cancer has linearly increased and correlated with the time-course of the study. The number of publication indexed in WoS-CC in 2015 was two times greater than that of 2006, which reached from 15 229 documents in 2006 to 30 667 documents in 2015. English Language accounted for 98% of total publications as the most dominant language. The vast majority of publications' type was in the form of original journal articles (64.7%). Based on Bradford scatterings law, the journal of "Cancer Research" was the most productive journal among the core journals, while the USA, China, and England were the most prolific countries in the field. The co-organization network indicated the dominant role of Harvard University in the field. Conclusion: The integrity of network indicated that scientists in the field of breast cancer

Authorship in Croatian copyright legislation from 1846 to 2007

2015-04-01

Full Text Available The aim of this paper is to investigate and present concepts of the author and his/her copyright work in copyright legislation that entered into force in Croatia from 1846 to 2007. 17 legal documents (acts, corrigenda, amendments were investigated using the content analysis method. The analysis of the results gives an insight into various cultural and sociological dimensions of authorship in the given time-frame. Special attention was paid to definitions of the author and his/her copyright work, examples of copyright works and exceptions related to the duration of copyright for different kinds of copyright works. As there had been no systematic overview of such legal documents in the available literature, they were briefly described in the first part of the paper, highlighting the important articles that stress the role of authors and their copyright work. In the analysis and summary we provide a systematic overview of the main concepts, with a special review of copyright laws in relation to new technologies and artistic forms: it is their relationship that testifies to the complexity of the term 'copyright work'. The paper shows that the basic perception of the author, his/her copyright works and their relations in the analysed copyright legislation has not changed significantly during this period of time. All legal documents refer to the examples of copyright work, and in 1957 a definition of copyright work was included, according to which copyright work is every spiritual (later referred to as intellectual creation. The concept of the author is strongly linked with the concept of author's copyright work. Various examples of copyright works allow us to see the difference between works that are permanent (e.g. literary works, music works, art works and works that are yet to be protected by copyright thanks to the development of technology and new features of artistic expression (e.g. photography, movies, computer programs.

All original research articles published in Annals of Internal Medicine, Archives of Internal Medicine, The BMJ, JAMA, The Lancet, and the New England Journal of Medicine (NEJM) for one issue every alternate month from February 1994 to June 2014. Time and journal of publication. Prevalence of female first authorship and its adjusted association with time of publication and journal, assessed using a multivariable logistic regression model that accounted for number of authors, study type and specialty/topic, continent where the study was conducted, and the interactions between journal and time of publication, study type, and continent. Estimates from this model were used to calculate adjusted odds ratios against the mean across the six journals, with 95% confidence intervals and P values to describe the associations of interest. The gender of the first author was determined for 3758 of the 3860 articles considered; 1273 (34%) were women. After adjustment, female first authorship increased significantly from 27% in 1994 to 37% in 2014 (Pauthorship decreasing; it also seemed to decline in recent years in The BMJ but started substantially higher (approximately 40%), and The BMJ had the highest total proportion of female first authors. Compared with the mean across all six journals, first authors were significantly less likely to be female in the NEJM (adjusted odds ratio 0.68, 95% confidence interval 0.53 to 0.89) and significantly more likely to be female in The BMJ (1.30, 1.01 to 1.66) over the study period. The representation of women among first authors of original research in high impact general medical journals was significantly higher in 2014 than 20 years ago, but it has plateaued in recent years and has declined in some journals.

Presenting results as dynamically generated co-authorship subgraphs in semantic digital library collections

Directory of Open Access Journals (Sweden)

James Powell

2012-02-01

Full Text Available Semantic web representations of data are by definition graphs, and these graphs can be explored using concepts from graph theory. This paper demonstrates how semantically mapped bibliographic metadata, combined with a lightweight software architecture and Web-based graph visualization tools, can be used to generate dynamic authorship graphs in response to typical user queries, as an alternative to more common text-based results presentations. It also shows how centrality measures and path analysis techniques from social network analysis can be used to enhance the visualization of query results. The resulting graphs require modestly more cognitive engagement from the user but offer insights not available from text.

Nkenke, Emeka; Seemann, Rudolf; Vairaktaris, Elefterios; Schaller, Hans-Günter; Rohde, Maximilian; Stelzle, Florian; Knipfer, Christian

2015-07-01

The aim of the present study was to perform a bibliometric analysis of the gender distribution of first and senior authorships in important oral and maxillofacial journals over the 30-year period from 1980 to 2010. Articles published in three representative oral and maxillofacial surgery journals were selected. The years 1980, 1990, 2000, and 2010 were chosen as representative points in time for article selection. Original research, case reports, technical notes, and reviews were included in the analysis. Case reports and technical notes were pooled in one group. For each article, the gender of the first author as well as that of the senior author was determined, based on the inspection of their first name. The type of article was determined and the country of origin of the article was documented. A total 1412 articles were subjected to the data analysis. A significant increase in female authorship in oral and maxillofacial surgery could be identified over the chosen 30-year period. However, the number of publications by male authors was still significantly higher at all points of time, exceeding those of female authors by at least 3.8 fold in 2010. As there is a trend towards feminization of medicine and dentistry, the results of the present study may serve as the basis for further analysis of the current situation, and the identification of necessary actions to accelerate the closure of the gender gap in publishing in oral and maxillofacial surgery.

2007-01-01

Deformation quantization is an algebraic but still geometrical way to define noncommutative spacetimes. In order to investigate corresponding gauge theories on such spaces, the geometrical formulation in terms of principal fibre bundles yields the appropriate framework. In this talk I will explain what should be understood by a deformation quantization of principal fibre bundles and how associated vector bundles arise in this context. (author)

Recognising contributions to work in research collaboratives: Guidelines for standardising reporting of authorship in collaborative research.

Science.gov (United States)

2018-04-01

Trainee research collaboratives (TRCs) have been revolutionary changes to the delivery of high-quality, multicentre research. The aim of this study was to define common roles in the conduct of collaborative research, and map these to academic competencies as set out by General Medical Council (GMC) in the United Kingdom. This will support trainers and assessors when judging academic achievements of those involved in TRC projects, and supports trainees by providing guidance on how to fulfil their role in these studies. A modified Delphi process was followed. Electronic discussion with key stakeholders was undertaken to identify and describe common roles. These were refined and mapped to GMC educational domains and International Committee of Medical Journal Editors authorship (ICJME) guidelines. The resulting roles and descriptions were presented to a face-to-face consensus meeting for voting. The agreed roles were then presented back to the electronic discussion group for approval. Electronic discussion generated six common roles. All of these were agreed in face-to-face meetings, where two further roles identified and described. All eight roles required skills that map to part of the academic requirements for surgical training in the UK. This paper presents a standardised framework for reporting authorship in collaborative group authored research publications. Linkage of collaborator roles to the ICMJE guidelines and GMC academic competency guidelines will facilitate incorporation into relevant training curricular and journal publication policies.

2001-01-01

To describe authorship according to gender in the articles published in four Spanish scientific journals of general medicine and public health, and to analyse the type of presentation of the results in relation to the sex of the subjects of the study. We examined 423 articles from four Spanish scientific journals published during 1998. 70.7% of the articles revised had a man as the first author. The sex difference was significant in the editorials (12.4% of the women vs. 29.8% of the men, p < 0.05). Stratification of the results by sex was presented in 167 articles and in 85.6% of them the information about men. Gender inequalities in the publication of scientific works in the field of general medicine and public health are found.

Part II: Should the h-index be modified? An analysis of the m-quotient, contemporary h-index, authorship value, and impact factor.

Khan, Nickalus R; Thompson, Clinton J; Taylor, Douglas R; Gabrick, Kyle S; Choudhri, Asim F; Boop, Frederick R; Klimo, Paul

2013-12-01

The widely accepted h-index depends on the citation analysis source and does not consider the authorship position, the journal's impact factor (IF), or the age of the paper or author. We investigated these factors in citation statistics of academic neurosurgeons. An uncorrected h-index and the m-quotient, which corrects for career length, were calculated by the use of Scopus and Google Scholar. In a subset of neurosurgeons, we computed the contemporary h-index (hc), which accounts for the age of the publications; the authorship value (AV), weighted by author position; and the journal IF. An "overall' average for AV and IF including most of an author's publications and an average for publications comprising the h-index ("h-index core") were calculated. When we used Google Scholar, the mean h-index was significantly greater than that calculated when we used Scopus (P = 0.0030). m-quotient and hc-index increased with academic rank, with an m-quotient >1 achieved by 69% of chairmen and 48% of professors. The effect of AV was greatest on the greater h-indices. The average IF for the h-index core was greater than the overall IF, which did not correlate with academic rank. Few neurosurgeons consistently publish in high-impact journals. Google Scholar tends to inflate the h-index. The m-quotient and hc-index allow comparisons of researchers across time. Although average journal IF did not differ significantly among neurosurgeons academic ranks, it should be noted for individuals who consistently publish in high-impact journals. We recommend the creation of individual bibliometric profiles to better compare the academic productivity of neurosurgeons. Copyright © 2013 Elsevier Inc. All rights reserved.

Copyright and Computer Generated Materials – Is it Time to Reboot the Discussion About Authorship?

Directory of Open Access Journals (Sweden)

Anne Fitzgerald

Full Text Available Computer generated materials are ubiquitous and we encounter them on a daily basis, even though most people are unaware that this is the case. Blockbuster movies, television weather reports and telephone directories all include material that is produced by utilising computer technologies. Copyright protection for materials generated by a programmed computer was considered by the Federal Court and Full Court of the Federal Court in Telstra Corporation Limited v Phone Directories Company Pty Ltd.  The court held that the White and Yellow pages telephone directories produced by Telstra and its subsidiary, Sensis, were not protected by copyright because they were computer-generated works which lacked the requisite human authorship.The Copyright Act 1968 (Cth does not contain specific provisions on the subsistence of copyright in computer-generated materials. Although the issue of copyright protection for computer-generated materials has been examined in Australia on two separate occasions by independently-constituted Copyright Law Review Committees over a period of 10 years (1988 to 1998, the Committees’ recommendations for legislative clarification by the enactment of specific amendments to the Copyright Act have not yet been implemented and the legal position remains unclear. In the light of the decision of the Full Federal Court in Telstra v Phone Directories it is timely to consider whether specific provisions should be enacted to clarify the position of computer-generated works under copyright law and, in particular, whether the requirement of human authorship for original works protected under Part III of the Copyright Act should now be reconceptualised to align with the realities of how copyright materials are created in the digital era.

Unmet needs for analyzing biological big data: A survey of 704 NSF principal investigators.

Science.gov (United States)

Barone, Lindsay; Williams, Jason; Micklos, David

2017-10-01

In a 2016 survey of 704 National Science Foundation (NSF) Biological Sciences Directorate principal investigators (BIO PIs), nearly 90% indicated they are currently or will soon be analyzing large data sets. BIO PIs considered a range of computational needs important to their work, including high performance computing (HPC), bioinformatics support, multistep workflows, updated analysis software, and the ability to store, share, and publish data. Previous studies in the United States and Canada emphasized infrastructure needs. However, BIO PIs said the most pressing unmet needs are training in data integration, data management, and scaling analyses for HPC-acknowledging that data science skills will be required to build a deeper understanding of life. This portends a growing data knowledge gap in biology and challenges institutions and funding agencies to redouble their support for computational training in biology.

Recognizing and Imitating Programmer Style: Adversaries in Program Authorship Attribution

Directory of Open Access Journals (Sweden)

Simko Lucy

2018-01-01

Full Text Available Source code attribution classifiers have recently become powerful. We consider the possibility that an adversary could craft code with the intention of causing a misclassification, i.e., creating a forgery of another author’s programming style in order to hide the forger’s own identity or blame the other author. We find that it is possible for a non-expert adversary to defeat such a system. In order to inform the design of adversarially resistant source code attribution classifiers, we conduct two studies with C/C++ programmers to explore the potential tactics and capabilities both of such adversaries and, conversely, of human analysts doing source code authorship attribution. Through the quantitative and qualitative analysis of these studies, we (1 evaluate a state-of-the-art machine classifier against forgeries, (2 evaluate programmers as human analysts/forgery detectors, and (3 compile a set of modifications made to create forgeries. Based on our analyses, we then suggest features that future source code attribution systems might incorporate in order to be adversarially resistant.

Do gender-based disparities in authorship also exist in cancer palliative care? A 15-year survey of the cancer palliative care literature.

Science.gov (United States)

Singh, Preet Paul; Jatoi, Aminah

2008-01-01

Women physicians in the United States publish less than men and advance academically at a slower pace. Do such gender-based disparities also occur in cancer palliative care, a field in which women appear to hold a strong interest? We undertook a detailed survey of the cancer palliative care literature. We selected 5 cancer palliative care journals on the basis of their high impact factors, and we assessed authorship for the years 1990, 1995, 2000, and 2005. We determined gender and highest educational degree for all US first and last authors. A total of 794 authors are the focus of this report. In 2005, 50% of first authors were women, but only 14% were women physicians. Similarly, 39% of senior authors were women during this year, but only 8% were women physicians. Over this 15-year period, no statistically significant trends were detected to indicate an increase in the number of women authors. These findings are sobering. Future efforts might focus on strategies to improve rates of authorship and, ultimately, improve rates of academic promotion for women interested in cancer palliative care.

Multiple authorship and article type in journals of urology across the Atlantic: trends over the past six decades.

Hammad, Fayez T; Shaban, Sami; Abu-Zidan, Fikri

2012-01-01

The aim of this research was to study the trends in authorship and type of article in European and North American journals of urology over the past 6 decades. Using a self-developed Visual Basic program, the number of authors per article and the type of article in four European journals (BJU International, Current Opinion in Urology, European Urology and Urologia Internationalis) and four North American journals (Journal of Urology, Urologic Clinics of North America, Urology and World Journal of Urology) were extracted from the PubMed website from January 1946 to October 2010, and the number of authors per article in each year was calculated in all the journals. The average number of authors per article has increased and the percentage of single-author articles has decreased in both European and American journals. An increase in the number of authors per article was observed mainly in original articles and case reports. Since the early 1980s, there has also been a decreasing percentage of published case reports and a general increase in the percentage of letters to the editor and editorials. The multiple-authorship trends observed in both European and North American urology journals were similar and appeared to be mainly due to changes in original articles and case reports.

The Authorship of a Musical Work and the Position of a Music Arranger (Avtorstvo glasbenega dela in položaj glasbenega aranžerja

Directory of Open Access Journals (Sweden)

Matija Damjan

2015-11-01

Full Text Available The creation of the final form of a piece of popular music usually involves several people: the composer, the lyricist, the music arranger, performers, sound engineers, etc. The article explores under what conditions the contributions of these persons constitute co-authorship of a piece of music and discusses in which phase a musical work can be considered finished. The copyright status of a music arranger is discussed in particular, whose work is usually defined in theory as adaptation of existing musical works, whereas in the practice of Slovenian popular music, arrangers often act as co-authors of new original music. The last part of the article examines the rules on the duration of rights in musical works produced in co-authorship and discusses in what way the ownership and the duration of copyrights in musical works is affected by Directive 2011/77/EU, which sets out unified rules on the duration of rights in musical compositions with words.

Whistleblowing as Employee’s Freedom of Speech. Günther Wallraff’s authorship as an illustrative case

Directory of Open Access Journals (Sweden)

Kristian Alm

2016-11-01

Full Text Available In this paper, we use Günther Wallraff’s authorship as an illustrative case in order to discuss whistleblowing understood as employees’ freedom of speech. We define the phenomenon according to significant democratic values; the public, fallible search for a deeper truth. When it comes to the sources, our point of departure is based on several of the most significant books published by Wallraff during a period from the end of the 1960-ties to the end of the 1980-ties. We trace some of the personal motivation behind his whistleblowing-project in Marxism and focus that he applies the undercover methods of journalism on the profession of journalists themselves. We argue that the Wallraff-case deals with three important issues; 1 investigative journalism linked to the discussion of the legitimacy of lying, 2 freedom of speech as an active choice of publically disclosing unethical behavior and different types of repression in organizations, and 3 Wallraff’s whistle-blowing in organizations as related to analogues modern types of freedom of speech. In the end, we use different social theories to explain why the type of whistleblowing Wallraff is famous for was necessary.

Late Print Culture’s Social Media Revolution: Authorship, Collaboration and Copy Machines

Directory of Open Access Journals (Sweden)

Kate Eichhorn

2013-05-01

Full Text Available This article examines the impact of copy machines on late twentieth-century print cultures. Specifically, this article makes a case for “dry copying,” the method of print reproduction perfected by Xerox in the late 1950s, as a unique medium rather than a weak imitation of other printing methods. Following the claim that the widespread availability of copy machines in the late twentieth century represented the arrival of a new medium, this article further examines how understandings of authorship, established with print culture, came undone in the era of the copy machine. Finally, this paper makes a case for understanding copy machines as a form of “social media” that opened up opportunities for writers, readers and publishers to create, share, exchange and comment on texts and images in communities and networks of their own making in the decades preceding the development of the web.

Barriers to energy efficiency in shipping: A triangulated approach to investigate the principal agent problem

International Nuclear Information System (INIS)

Rehmatulla, Nishatabbas; Smith, Tristan

2015-01-01

Energy efficiency is a key policy strategy to meet some of the challenges being faced today and to plan for a sustainable future. Numerous empirical studies in various sectors suggest that there are cost-effective measures that are available but not always implemented due to existence of barriers to energy efficiency. Several cost-effective energy efficient options (technologies for new and existing ships and operations) have also been identified for improving energy efficiency of ships. This paper is one of the first to empirically investigate barriers to energy efficiency in the shipping industry using a novel framework and multidisciplinary methods to gauge implementation of cost-effective measures, perception on barriers and observations of barriers. It draws on findings of a survey conducted of shipping companies, content analysis of shipping contracts and analysis of energy efficiency data. Initial results from these methods suggest the existence of the principal agent problem and other market failures and barriers that have also been suggested in other sectors and industries. Given this finding, policies to improve implementation of energy efficiency in shipping need to be carefully considered to improve their efficacy and avoid unintended consequences. -- Highlights: •We provide the first analysis of the principal agent problem in shipping. •We develop a framework that incorporates methodological triangulation. •Our results show the extent to which this barrier is observed and perceived. •The presence of the barrier has implications on the policy most suited to shipping

Full Text Available You finished your PhD, have been a postdoc for a while, and you start wondering, “What's next?” Suppose you come to the conclusion that you want to stay in academia, and move up the ladder to become a principal investigator (PI. How does one reach this goal given that academia is one of the most competitive environments out there? And suppose you do manage to snatch your dream position, how do you make sure you hit the ground running? Here we report on the workshop “P2P - From Postdoc To Principal Investigator” that we organized at ISMB 2012 in Long Beach, California. The workshop addressed some of the challenges that many postdocs and newly appointed PIs are facing. Three experienced PIs, Florian Markowetz (Group Leader, Cambridge Research Institute, Cancer Research UK, Gary Bader (Associate Professor, The Donnelly Centre, University of Toronto, and Philip Bourne (Professor, Skaggs School of Pharmacy and Pharmaceutical Sciences, University of California San Diego, provided insight into the transition from a trainee to PI and shared advice on how to make the best out it.

Follow-up of an intelligent odd-mannered teenager with del(3)(p26). Remarks on authorship and ethical commitment.

Science.gov (United States)

Rivera, H; Domínguez, M G; Matute, E

2006-01-01

A male teenager formerly found to have a 46,XY,del(3)(p26)de novo karyotype was restudied. At the age of 14(8/12) yr, he attends the last grade of middle school and was a cooperating teenager with slender habitus, severe myopia, prominent nose, sacral dimples, pubertal stage Tanner III, and multiple surgical scars. Neuropsychological studies revealed a full scale IQ of 95 with slow performance (WISC-IV Spanish test) as well as an internalizing behavioral profile, poor social skills, a mild attention deficit, somatic complaints, and a feminized gender role. FISH with the 3p subtelomeric probe revealed that the deleted chromosome actually lacked the specific signal (n=10 cells). The patient's average intelligence confirms that euchromatic imbalances do not necessarily cause mental retardation and suggests that his deletion actually included the CALL gene, the Contactin 4 gene and other 3p26 genes related to intellectual capabilities; yet, the resulting hemizygosity either did not lead to haploinsufficiency or was minimally expressed. Moreover, the patient's peculiar cognitive and behavioral profile suggests that the 3p26 deletion is associated with a distinctive neuropsychological phenotype. Incidentally we comment on authorship and publication ethics in order to urge our institutional ethics committee to arbitrate authorship conflicts and thereby be consistent with its ethical commitment.

The European Zebrafish Principal Investigator Meeting (EZPM) is an ideal forum for group leaders using this fantastic animal model not only to discuss science but also to strengthen their interactions, to push forward technological advances, and to define guidelines for the use of this fish in research. The city of Lisbon (Portugal) was voted by the European group leaders to be the setting for the 4th EZPM, and the organizing committee, composed by Leonor Saúde (iMM Lisboa, PT), Susana Lopes (CEDOC, PT), Michael Orger (Champalimaud Foundation, PT), Rui Oliveira (ISPA, PT), and António Jacinto (CEDOC, PT), was very enthusiastic to organize a productive event. The 4th EZPM took place from March 15 to 19 at Pavilhão do Conhecimento, a Science Museum and Educational Center winner of The Great Prize FAD of Arquitecture 1999 and The Society for Environmental Graphic Design Award 2011. Over 5 days, 135 group leaders (89 men and 46 women) coming from 19 different European countries and also from the United States, Turkey, Israel, Chile, and Singapore presented and discussed their recent research achievements. In addition to the scientific oral and poster presentations, the group leaders gathered in very lively community sessions on morphants versus mutants (chaired by Didier Stainier, Max Planck Institute for Heart and Lung Research, DE), funding issues (chaired by Uwe Strahle, KIT-ITG, DE), and gender equality (chaired by Corinne Houart, KCL, United Kingdom). One of the highlights of the 4th EZPM was the guided visit to Oceanário de Lisboa, an international award-winning place that celebrates life with a stunning display of living aquatic creatures.

Authorship, Autobiography and the Archive: Marilyn on Marilyn, Television and Documentary Theory

Directory of Open Access Journals (Sweden)

Paul Kerr

2015-12-01

Full Text Available In 2004, documentary theorist Michael Renov described ‘the recent turn to filmic autobiography’ as ‘the defining trend of “post-verite” documentary practice...’ In 2008 Renov went further still, suggesting that ‘the very idea of autobiography challenges/reinvents the VERY IDEA of documentary.’ Archive based autobiographical filmmaking, meanwhile, is even more problematic for documentary theory. Indeed, a number of recent documentaries, because of their status somewhere in the spectrum between biography and autobiography, have prompted the construction of an entirely new conceptual category, deploying archival film, often in the form of home movies, to document the lives of their human subjects in Renov’s formulation ‘shared textual authority’.  In this article I examine one of ‘my’ own archive based documentaries, ‘Marilyn on Marilyn’ (BBC2 2001, as a way of asking questions not just about biographical and autobiographical documentary but also - and perhaps more urgently - about attributions of authorship in archive-based documentary.

Publication among academic staff and students: an analysis from the ethical perspective

Directory of Open Access Journals (Sweden)

María Teresa Urrutia Soto

2015-12-01

Full Text Available This article analyzes, from the ethical perspective, the authorship of particles carried out among students and professors and their potential conflicts. After the literature review, it has been found that the Vancouver criteria that should be fulfilled for the attribution of authorship of an article are not popularly known by students and academic staff. Many problems are posed in this area, among which the following are highlighted: ghost writer, honorary author, and incorrect assignment in the order authors should appear. The professor-student relationship brings with it implicit risks that could lead to conflict, against which it is the academician who should be cautious to curtail any ethical fault when assigning the authors. The measures recommended to avoid conflicts of authorship among students and academic staff are: early assignment of the authors, reflection among academicians, education to students/academic staff, and external control conducted by journal editors. Conclusion is that lack of awareness of the criteria of authorship by academicians and students is the principal problem in the attribution of authorships. It is indispensable to improve this knowledge and look after the application of said criteria in practice.

Background: The purpose of this study was to detect the prevalence of ghost and honorary authors and its determinant factors in bio-medical journals of Iran. Methods: The study was done in 2009–10 in Tehran, Kerman, and Iran Medical Universities, Iran. We contacted the first or corresponding authors of the papers had published papers in the recent two issues of Iranian Journal of Public Health, Journal of Kerman University of Medical Sciences, and Tehran University Medical Journal. They explored the role of each coauthor and others who had done mouthing for the paper. Then, according to ICMJE criteria, we counted how many of them are real, honorary or ghost author. For the analysis, we utilized two databases. One included articles as the records and the other included authors as the records. Results: From 124 articles, with 536 authors, 301 (56.1%) were honorary authors. Each article had 4.35 authors on average, while 2.4 of them were honorary authors. The percentage of honorary author in basic science articles was about 6% more than the articles of clinical sciences. Moreover, 89% of articles had at least one honorary author. About 20% of all articles had more than three honorary authors. Besides, 25 (21.43%) authors confessed they had colleague(s) omitted from the authors list, while only one (0.81%) of them met the authorship criteria. The percentage of agreement between the corresponding and the remaining authors on the number of honorary of the authors was about 47.4% (Kappa= 0.27, P= 0.01). Conclusion: It seems that the present data might assist the authorities to make a decisive decision on amending the process of authorship in Iran. PMID:23113050

National Institutes of Health (NIH) grants are becoming increasingly competitive in the academic research arena. Identifying NIH funding disparities is an important step in improving academic diversity. To examine recent NIH funding trends in dermatology. Retrospective study with linear regression analysis and repeated-measures analysis of variance of all NIH grants awarded to departments of dermatology from fiscal year 2009 to 2014. Funding data were exported from the NIH Research Portfolio Online Reporting Tools Expenditures and Results. Publication data were drawn from Scopus. All NIH-funded principal investigators in dermatology were categorized by their academic degree and sex. The NIH funding trends were compared by investigator degree (MD, PhD, or MD/PhD) and sex. A total of 1292 NIH-funded grants were awarded to dermatology research from fiscal year 2009 through 2014. Adjusted NIH funding for dermatologic research diminished by 4.6% from $67.3 million in 2009 to $64.2 million in 2014, with a nadir of $58.6 million in 2013. Funding for the NIH's Research Project Grant Program (R01) decreased by 21.0% from $43.9 million to $34.7 million during this period. The dollar amount of NIH funding significantly trended down for investigators with an MD degree by $1.35 million per year from $23.6 million in 2009 to $18.4 million in 2014 (P = .02) while there was no significant change in NIH funding for MD/PhD (from $17.6 million in 2009 to $19.8 million in 2014; P = .44) and PhD investigators (from $26.1 million in 2009 to $25.9 million in 2014; P = .74). Similarly, the total dollar amount of R01 grants awarded to principal investigators with only an MD degree trended down by $1.4 million per year from $13.2 million in 2009 to $6.0 million in 2014 (P dermatology trended down significantly compared with the trend of their male counterparts (from 49 women in 2009 to 43 women in 2014 vs from 84 men in 2009 to 97 men in 2014; P = .04).

The individual’s triumph: the eighteenth-century consolidation of authorship and art historiography

Directory of Open Access Journals (Sweden)

David Pullins

2017-06-01

Full Text Available The eighteenth-century consolidation of authorial identity – apparent in Salon livrets, art criticism, sales catalogs, inventories, the theoretical development of maniera, signing and hanging practices – was crucial to subsequent, nineteenth-century Romantic notions of what constituted individual authorship and to the kinds of eighteenth-century painting that were eventually written into or out of art history. Situating eighteenth-century paintings and drawings executed by multiple hands in a longue durée between workshop and court artisan practices on one hand and nineteenth-century singularity on the other, this article recovers an alternate thread of authorial identity. Having failed to find a place in art historiography as it developed in the nineteenth and twentieth centuries, these examples in fact find sympathetic counterparts in late twentieth-century theories of the author function. Reconsidering both these multi-authored works and writing about them helps to clarify the historical specificity with which we conceive of the relationship between object and maker.

Full Text Available The purpose of this study was to investigate the leadership roles and practices of the principal in improving school effectiveness. This descriptive study involved the principal , counselor, and 11 teachers from the Tonsley Park Primary School in South Australia. The findings showed that all respondents generally regarded team leader as the most important role, while supervisor was rated as the least important. Of the 20 tasks observed, generally revealed that a principal should work cooperatively with staff to ensure more effective use of their skills. While, the task of a principal in making decisions on staff development programs was not necessarily expected by the practicing teachers. All respondents considered organization coordination as the most important area within which a principal should provide more leadership, while curriculum or instructional improvement and innovation was regarded as the least important

Supporting the Cybercrime Investigation Process: Effective Discrimination of Source Code Authors Based on Byte-Level Information

Science.gov (United States)

Frantzeskou, Georgia; Stamatatos, Efstathios; Gritzalis, Stefanos

Source code authorship analysis is the particular field that attempts to identify the author of a computer program by treating each program as a linguistically analyzable entity. This is usually based on other undisputed program samples from the same author. There are several cases where the application of such a method could be of a major benefit, such as tracing the source of code left in the system after a cyber attack, authorship disputes, proof of authorship in court, etc. In this paper, we present our approach which is based on byte-level n-gram profiles and is an extension of a method that has been successfully applied to natural language text authorship attribution. We propose a simplified profile and a new similarity measure which is less complicated than the algorithm followed in text authorship attribution and it seems more suitable for source code identification since is better able to deal with very small training sets. Experiments were performed on two different data sets, one with programs written in C++ and the second with programs written in Java. Unlike the traditional language-dependent metrics used by previous studies, our approach can be applied to any programming language with no additional cost. The presented accuracy rates are much better than the best reported results for the same data sets.

Gertruida M. Steyn

2013-04-01

Full Text Available This study focussed on the socialisation of a new principal in a South African primary school with a strong Christian culture. He was appointed when the predecessor retired after more than two decades. The conceptual framework focuses on the three phases of socialisation: professional socialisation, organisational socialisation and occupational identity, which are used to interpret the study. A qualitative study, which occurred during two phases, investigated the phenomenon, principal succession, in the particular school. The data collection methods included a number of interviews with the principal, a focus group interview with staff members who experienced the previous principal’s leadership practice, and individual interviews with staff members. The following categories emerged from the data analysis: Recalling the previous principal: ‘One sees Mr X [the predecessor] everywhere’; Entry and orientation: ‘I found it intimidating initially’; and Immersion and reshaping: ‘Reins that previously were a bit slack, he is now pulling tight’.Die sosialisering van ’n primêre skoolhoof in Suid-Afrika.

Jurgita Kapočiūtė-Dzikienė

2014-12-01

Full Text Available In our paper we present a corpus of transcribed Lithuanian parliamentary speeches. The corpus is prepared in a specific format, appropriate for different authorship identification tasks. The corpus consists of approximately 111 thousand texts (24 million words. Each text matches one parliamentary speech produced during an ordinary session from the period of 7 parliamentary terms starting on March 10, 1990 and ending on December 23, 2013. The texts are grouped into 147 categories corresponding to individual authors, therefore they can be used for authorship attribution tasks; besides, these texts are also grouped according to age, gender and political views, therefore they are also suitable for author profiling tasks. Whereas short texts complicate recognition of author speaking style and are ambiguous in relation to the style of other authors, we incorporated only texts containing not less than 100 words into the corpus. In order to make each category as comprehensive and representative as possible, we included only those authors, who produced speeches at least 200 times. All the texts are lemmatized, morphologically and syntactically annotated, tokenized into the character n-grams. The statistical information of the corpus is also available. We have also demonstrated that the created corpus can be effectively used in authorship attribution and author profiling tasks with supervised machine learning methods. The corpus structure also allows using it with unsupervised machine learning methods and can be used for creation of rule-based methods, as well as in different linguistic analyses.

Geometry of Quantum Principal Bundles. Pt. 1

International Nuclear Information System (INIS)

Durdevic, M.

1996-01-01

A theory of principal bundles possessing quantum structure groups and classical base manifolds is presented. Structural analysis of such quantum principal bundles is performed. A differential calculus is constructed, combining differential forms on the base manifold with an appropriate differential calculus on the structure quantum group. Relations between the calculus on the group and the calculus on the bundle are investigated. A concept of (pseudo)tensoriality is formulated. The formalism of connections is developed. In particular, operators of horizontal projection, covariant derivative and curvature are constructed and analyzed. Generalizations of the first Structure Equation and of the Bianchi identity are found. Illustrative examples are presented. (orig.)

Multiple authorship trends in prestigious journals from 1950 to 2005.

Science.gov (United States)

Shaban, Sami

2007-06-01

Editors of many established journals have noticed throughout the years an increase in the number of authors per article. I wish to put this theory to rest by calculating this linear increase for several prestigious journals. I chose several prestigious journals and obtained authorship information for all articles published throughout the existence of these journals from the PubMed website. The data collection was performed on January 22, 2006, and was performed for the years from 1/1/1950 to 12/31/2005 for each journal. With the use of several self-developed software programs and database queries, I was able to calculate the average number of authors per article per year and the percent of single-author articles per year for these journals. The result confirms the increase in the number of authors per article in a linear fashion for all examined journals. The result also shows a decrease in the number of single-author articles in a sporadic fashion for all examined journals. The data collection and calculation method can be used for any journal indexed in PubMed. The resulting trends are likely due to the increasing complexity of research, the increasing pressure on researchers to publish or perish, among others. This paper, however, focuses less on the reasons for this trend and more on the computerized methods used to obtain the results.

Co-authorship Network Analysis: A Powerful Tool for Strategic Planning of Research, Development and Capacity Building Programs on Neglected Diseases

Morel, Carlos Medicis; Serruya, Suzanne Jacob; Penna, Gerson Oliveira; Guimarães, Reinaldo

2009-01-01

Background New approaches and tools were needed to support the strategic planning, implementation and management of a Program launched by the Brazilian Government to fund research, development and capacity building on neglected tropical diseases with strong focus on the North, Northeast and Center-West regions of the country where these diseases are prevalent. Methodology/Principal Findings Based on demographic, epidemiological and burden of disease data, seven diseases were selected by the Ministry of Health as targets of the initiative. Publications on these diseases by Brazilian researchers were retrieved from international databases, analyzed and processed with text-mining tools in order to standardize author- and institution's names and addresses. Co-authorship networks based on these publications were assembled, visualized and analyzed with social network analysis software packages. Network visualization and analysis generated new information, allowing better design and strategic planning of the Program, enabling decision makers to characterize network components by area of work, identify institutions as well as authors playing major roles as central hubs or located at critical network cut-points and readily detect authors or institutions participating in large international scientific collaborating networks. Conclusions/Significance Traditional criteria used to monitor and evaluate research proposals or R&D Programs, such as researchers' productivity and impact factor of scientific publications, are of limited value when addressing research areas of low productivity or involving institutions from endemic regions where human resources are limited. Network analysis was found to generate new and valuable information relevant to the strategic planning, implementation and monitoring of the Program.

Principal stratification in causal inference.

Science.gov (United States)

Frangakis, Constantine E; Rubin, Donald B

2002-03-01

Many scientific problems require that treatment comparisons be adjusted for posttreatment variables, but the estimands underlying standard methods are not causal effects. To address this deficiency, we propose a general framework for comparing treatments adjusting for posttreatment variables that yields principal effects based on principal stratification. Principal stratification with respect to a posttreatment variable is a cross-classification of subjects defined by the joint potential values of that posttreatment variable tinder each of the treatments being compared. Principal effects are causal effects within a principal stratum. The key property of principal strata is that they are not affected by treatment assignment and therefore can be used just as any pretreatment covariate. such as age category. As a result, the central property of our principal effects is that they are always causal effects and do not suffer from the complications of standard posttreatment-adjusted estimands. We discuss briefly that such principal causal effects are the link between three recent applications with adjustment for posttreatment variables: (i) treatment noncompliance, (ii) missing outcomes (dropout) following treatment noncompliance. and (iii) censoring by death. We then attack the problem of surrogate or biomarker endpoints, where we show, using principal causal effects, that all current definitions of surrogacy, even when perfectly true, do not generally have the desired interpretation as causal effects of treatment on outcome. We go on to forrmulate estimands based on principal stratification and principal causal effects and show their superiority.

Full Text Available Postdoc positions, intended to be advanced or continued research training in a field, are a part of the physics education research (PER enterprise yet little is known about them. PER postdocs differ from their traditional physics counterparts in that they may have different education and research experiences. This study examined the types of postdoc positions available as well as what hiring is like. To determine the types of postdoc positions available, we used the advertisements posted in PERJobs blog. To learn more about hiring practices, interviews were conducted with both principal investigators (PIs and current and former postdocs. Results show that many PER postdoc positions have been available since 2008, with many of these advertisements indicating that the PI will consider hiring someone with a physics or a PER or science, technology, engineering, or mathematics education background. The interviews indicate that there is no typical way for hiring PER postdocs. Some aspects that PIs consider include the background of the candidates and how well the candidates fit in with the group. Postdocs likewise consider whether they like the research group when accepting offers. For both, having ties to the PER community is important for hiring. Overall, PIs and postdocs have been satisfied. Postdocs who were originally in traditional physics have felt that being a PER postdoc has allowed them to transition to PER. In giving advice, both PIs and postdocs reiterate the importance of connecting to the community, evaluating the postdoc position as a stepping stone in the career trajectory, and holistically considering candidates.

Alqaydi, Ahlam R; Kanavakis, Georgios; Naser-Ud-Din, Shazia; Athanasiou, Athanasios E

2017-12-08

This study was conducted to explore authorship characteristics and publication trends of all orthodontic randomized controlled trials (RCTs), systematic reviews (SRs), and meta-analyses (MAs) published in non-orthodontic journals with impact factor (IF). Appropriate research strategies were developed to search for all articles published until December 2015, without restrictions regarding language or publication status. The initial search generated 4524 results, but after application of the inclusion criteria, the final number of articles was reduced to 274 (SRs: 152; MAs: 36; and RCTs: 86). Various authorship characteristics were recorded for each article. Frequency distributions for all parameters were explored with Pearson chi-square for independence at the 0.05 level of significance. More than half of the included publications were SRs (55.5 per cent), followed by RCTs (31.4 per cent) and MAs (13.1 per cent); one hundred seventy-eight (65 per cent) appeared in dental journals and 96 (35 per cent) were published in non-dental journals. The last decade was significantly more productive than the period before 2006, with 236 (86.1 per cent) articles published between 2006 and 2015. European countries produced 51.5 per cent of the total number of publications, followed by Asia (18.6 per cent) and North America (USA and Canada; 16.8 per cent). Studies published in journals without IF were not included. Level-1 evidence orthodontic literature published in non-orthodontic journals has significantly increased during 2006-15.

Network effects on scientific collaborations.

Directory of Open Access Journals (Sweden)

Shahadat Uddin

Full Text Available BACKGROUND: The analysis of co-authorship network aims at exploring the impact of network structure on the outcome of scientific collaborations and research publications. However, little is known about what network properties are associated with authors who have increased number of joint publications and are being cited highly. METHODOLOGY/PRINCIPAL FINDINGS: Measures of social network analysis, for example network centrality and tie strength, have been utilized extensively in current co-authorship literature to explore different behavioural patterns of co-authorship networks. Using three SNA measures (i.e., degree centrality, closeness centrality and betweenness centrality, we explore scientific collaboration networks to understand factors influencing performance (i.e., citation count and formation (tie strength between authors of such networks. A citation count is the number of times an article is cited by other articles. We use co-authorship dataset of the research field of 'steel structure' for the year 2005 to 2009. To measure the strength of scientific collaboration between two authors, we consider the number of articles co-authored by them. In this study, we examine how citation count of a scientific publication is influenced by different centrality measures of its co-author(s in a co-authorship network. We further analyze the impact of the network positions of authors on the strength of their scientific collaborations. We use both correlation and regression methods for data analysis leading to statistical validation. We identify that citation count of a research article is positively correlated with the degree centrality and betweenness centrality values of its co-author(s. Also, we reveal that degree centrality and betweenness centrality values of authors in a co-authorship network are positively correlated with the strength of their scientific collaborations. CONCLUSIONS/SIGNIFICANCE: Authors' network positions in co-authorship

African-American Female Students and STEM: Principals' Leadership Perspectives

Science.gov (United States)

Sampson, Kristin Morgan

As the U.S. becomes more diverse, school leaders, major corporations, and areas of national defense continue to investigate science, technology, engineering and math (STEM) education issues. African-American female students have historically been underrepresented in STEM fields, yet educational leadership research, examining this population is limited. The purpose of this qualitative study was to explore how principals support African-American female students in schools with a STEM program. The Critical Race Theory (CRT)was used as a theoretical framework to highlight the inadequacies to support educational inequalities. The application of the CRT in this study is due to the embedded inequality practices within the educational system, that have resulted in the underrepresentation of African-American female students in STEM. To complement CRT, the transformative leadership model was also utilized to examine the emancipatory leadership practices principals utilized. These theories framed the context of this study by recognizing the need to address how support is actualized to African-American female students in STEM by their principals. A case study approach was an appropriate method to answer the two research questions, 1) How do principals feel they support African-American female students in their STEM programs? and 2) What practices do principals engage in that support underrepresented students in STEM? This approach intended to uncover how a principal leads a multifaceted population of underrepresented students in STEM programs. Two principals of STEM schools, where more than 50% of the population were African-American, were interviewed and observed completing daily operations at community-wide events. The STEM Coordinators and a teacher were also interviewed, and test scores were examined to provide further information about the STEM program, and public records were obtained to analyze the principals' means of communication. I found that principals supported

Principal chiral model on superspheres

International Nuclear Information System (INIS)

Mitev, V.; Schomerus, V.; Quella, T.

2008-09-01

We investigate the spectrum of the principal chiral model (PCM) on odd-dimensional superspheres as a function of the curvature radius R. For volume-filling branes on S 3 vertical stroke 2 , we compute the exact boundary spectrum as a function of R. The extension to higher dimensional superspheres is discussed, but not carried out in detail. Our results provide very convincing evidence in favor of the strong-weak coupling duality between supersphere PCMs and OSP(2S+2 vertical stroke 2S) Gross-Neveu models that was recently conjectured by Candu and Saleur.

Erden Aki, Özlem; Özçelik Eroğlu, Elçin; Uslu, Ece

2015-03-01

The number of women with careers in medicine and with academic positions at medical schools has increased substantially since the 1980s; however, women remain underrepresented in medical academia, which may be because of the fewer research publications authored by women. This study aimed to determine the gender distribution among Turkish authors of psychiatry articles published in international scientific journals during a 30-year period. The ISI Web of Science database was searched for all psychiatry publications between 1980 and 2009 using the search term Turkey. All articles were classified according to publication period (1980-1989, 1990-1999, 2000-2004, and 2005-2009), gender of the first and last authors, first author title, total number of authors, and type of article. In all, 1961 articles meet the study criteria. The first author of 36.5% of the articles and 34.9% of last authors were women. The percentage of female first and last authors did not differ according to publication period (p=0.57). To the best of our knowledge this is the first study to examine gender and authorship of psychiatric research in Turkey. In total, 33% of academic positions in Turkish university psychiatry departments were occupied by women, which is comparable to the percentage of female first authors of psychiatric research papers from Turkey. It could be concluded that women academics in psychiatry departments from state universities are as reproductive as their male counterparts, but there is still a "gender gap" in psychiatry field in our country.

Steering the Author Discourse: The Construction of Authorship in Quality TV, and the Case of Game of Thrones

Directory of Open Access Journals (Sweden)

Tobias Steiner

2015-12-01

Full Text Available This essay examines how the authorship is discursively constructed and employed as an indicator of quality in the marketing of US cable network HBO's TV series Game of Thrones (2011-. It relates the authorial concept of literary studies to that in the visual media and analyses mise-en-scène and narrative structure of the show pilot in order to detect markers of an authorial voice within the text. Subsequently, it turns to a selection of paratexts – critical reviews, producers' commentaries and special features of the show’s DVD box set – to show how the team of producers help manufacture and promote the presence of a showrunner-auteur collective in order to foster a perception of this text as a ‘quality TV’ narrative.

Woolley, Karen L; Gertel, Art; Hamilton, Cindy W; Jacobs, Adam; Snyder, Gene P

2013-01-01

In this commentary, we present evidence that unethical authorship (eg, guest and ghost authoring) and other publication practices are not restricted to the pharmaceutical industry; they also occur in academia. Such practices are not an industry problem--they are a research problem. To enhance trust in industry-sponsored research, companies have made rapid and far-reaching changes to their publication guidelines, policies, and procedures. Professional medical writers have adopted, and continue to implement, these changes. Although evidence indicates that industry practices are improving, there is certainly more to do, both in industry and academia. We invite readers to join ongoing efforts to promote ethical publication practices.

Physicochemical properties of different corn varieties by principal components analysis and cluster analysis

International Nuclear Information System (INIS)

Zeng, J.; Li, G.; Sun, J.

2013-01-01

Principal components analysis and cluster analysis were used to investigate the properties of different corn varieties. The chemical compositions and some properties of corn flour which processed by drying milling were determined. The results showed that the chemical compositions and physicochemical properties were significantly different among twenty six corn varieties. The quality of corn flour was concerned with five principal components from principal component analysis and the contribution rate of starch pasting properties was important, which could account for 48.90%. Twenty six corn varieties could be classified into four groups by cluster analysis. The consistency between principal components analysis and cluster analysis indicated that multivariate analyses were feasible in the study of corn variety properties. (author)

Silvestre, Jason; Wu, Liza C; Lin, Ines C; Serletti, Joseph M

2016-07-01

An increasing number of women are entering the medical profession, but plastic surgery remains a male-dominated profession, especially within academia. As academic aspirations and advancement depend largely on research productivity, the authors assessed the number of articles authored by women published in the journal Plastic and Reconstructive Surgery. Original articles in Plastic and Reconstructive Surgery published during the years 1970, 1980, 1990, 2000, 2004, and 2014 were analyzed. First and senior authors with an M.D. degree and U.S. institutional affiliation were categorized by gender. Authorship trends were compared with those from other specialties. Findings were placed in the context of gender trends among plastic surgery residents in the United States. The percentage of female authors in Plastic and Reconstructive Surgery increased from 2.4 percent in 1970 to 13.3 percent in 2014. Over the same time period, the percentage of female plastic surgery residents increased from 2.6 percent to 32.5 percent. By 2014, there were more female first authors (19.1 percent) than senior authors (7.7 percent) (p < 0.001). As a field, plastic surgery had fewer female authors than other medical specialties including pediatrics, obstetrics and gynecology, general surgery, internal medicine, and radiation oncology (p < 0.05). The increase in representation of female authors in plastic surgery is encouraging but lags behind advances in other specialties. Understanding reasons for these trends may help improve gender equity in academic plastic surgery.

Multiscale principal component analysis

International Nuclear Information System (INIS)

Akinduko, A A; Gorban, A N

2014-01-01

Principal component analysis (PCA) is an important tool in exploring data. The conventional approach to PCA leads to a solution which favours the structures with large variances. This is sensitive to outliers and could obfuscate interesting underlying structures. One of the equivalent definitions of PCA is that it seeks the subspaces that maximize the sum of squared pairwise distances between data projections. This definition opens up more flexibility in the analysis of principal components which is useful in enhancing PCA. In this paper we introduce scales into PCA by maximizing only the sum of pairwise distances between projections for pairs of datapoints with distances within a chosen interval of values [l,u]. The resulting principal component decompositions in Multiscale PCA depend on point (l,u) on the plane and for each point we define projectors onto principal components. Cluster analysis of these projectors reveals the structures in the data at various scales. Each structure is described by the eigenvectors at the medoid point of the cluster which represent the structure. We also use the distortion of projections as a criterion for choosing an appropriate scale especially for data with outliers. This method was tested on both artificial distribution of data and real data. For data with multiscale structures, the method was able to reveal the different structures of the data and also to reduce the effect of outliers in the principal component analysis

The effective potential in universal like coordinates(U, V, θ, φ), which are smooth across the event horizon is derived and investigated the ISCO(Innermost Stable Circular Orbits) explicitly in these coordinates for extremal Kerr spacetime. Extremization of the effective potential for timelike circular orbit shows that the existence of a stable circular geodesics in the extremal spacetime for direct orbit, precisely on the event horizon in terms of the radial coordinate which coincides with the principal null geodesic congruences of the event horizon. These null geodesic congruences mold themselves to the spacetime curvature in such a way that Weyl conformal tensor and its dual are vanished, that is why they are in-fact doubly degenerate principal null congruences.

Full Text Available It is difficult to find in Brazilian literature works in which discursive constructions and narratives of women appear figured by male power. Prevail in them, for example, preachings of black female characters overwhelmed not only by patriarchy, as well as representations surrounded by traces of inferiority, virility and strong negative valuation of their ethnic and cultural diversity. When you add the fact that the invisibility of black women's writing, the scene of literary tradition, we can more easily understand the literature you want distinctive, innovative and transgressive, produced by them. Thus, this text will make an interpretative reading practices (un silencing of literary authorship and literary voices of black women writers, who, as discursive formations, march away from stigmas and deletions and coming brands of otherness.

Principal Curves on Riemannian Manifolds.

Science.gov (United States)

Hauberg, Soren

2016-09-01

Euclidean statistics are often generalized to Riemannian manifolds by replacing straight-line interpolations with geodesic ones. While these Riemannian models are familiar-looking, they are restricted by the inflexibility of geodesics, and they rely on constructions which are optimal only in Euclidean domains. We consider extensions of Principal Component Analysis (PCA) to Riemannian manifolds. Classic Riemannian approaches seek a geodesic curve passing through the mean that optimizes a criteria of interest. The requirements that the solution both is geodesic and must pass through the mean tend to imply that the methods only work well when the manifold is mostly flat within the support of the generating distribution. We argue that instead of generalizing linear Euclidean models, it is more fruitful to generalize non-linear Euclidean models. Specifically, we extend the classic Principal Curves from Hastie & Stuetzle to data residing on a complete Riemannian manifold. We show that for elliptical distributions in the tangent of spaces of constant curvature, the standard principal geodesic is a principal curve. The proposed model is simple to compute and avoids many of the pitfalls of traditional geodesic approaches. We empirically demonstrate the effectiveness of the Riemannian principal curves on several manifolds and datasets.

Reforms such as technology-enhanced instruction require principal leadership. Yet, many principals report that they need help to guide implementation of science and technology reforms. We identify strategies for helping principals provide this leadership. A two-phase design is employed. In the first phase we elicit principals' varied ideas about the Technology-enhanced Learning in Science (TELS) curriculum materials being implemented by teachers in their schools, and in the second phase we engage principals in a leadership workshop designed based on the ideas they generated. Analysis uses an emergent coding scheme to categorize principals' ideas, and a knowledge integration framework to capture the development of these ideas. The analysis suggests that principals frame their thinking about the implementation of TELS in terms of: principal leadership, curriculum, educational policy, teacher learning, student outcomes and financial resources. They seek to improve their own knowledge to support this reform. The principals organize their ideas around individual school goals and current political issues. Principals prefer professional development activities that engage them in reviewing curricula and student work with other principals. Based on the analysis, this study offers guidelines for creating learning opportunities that enhance principals' leadership abilities in technology and science reform.

Combined approach based on principal component analysis and canonical discriminant analysis for investigating hyperspectral plant response

Directory of Open Access Journals (Sweden)

Full Text Available Hyperspectral (HS data represents an extremely powerful means for rapidly detecting crop stress and then aiding in the rational management of natural resources in agriculture. However, large volume of data poses a challenge for data processing and extracting crucial information. Multivariate statistical techniques can play a key role in the analysis of HS data, as they may allow to both eliminate redundant information and identify synthetic indices which maximize differences among levels of stress. In this paper we propose an integrated approach, based on the combined use of Principal Component Analysis (PCA and Canonical Discriminant Analysis (CDA, to investigate HS plant response and discriminate plant status. The approach was preliminary evaluated on a data set collected on durum wheat plants grown under different nitrogen (N stress levels. Hyperspectral measurements were performed at anthesis through a high resolution field spectroradiometer, ASD FieldSpec HandHeld, covering the 325-1075 nm region. Reflectance data were first restricted to the interval 510-1000 nm and then divided into five bands of the electromagnetic spectrum [green: 510-580 nm; yellow: 581-630 nm; red: 631-690 nm; red-edge: 705-770 nm; near-infrared (NIR: 771-1000 nm]. PCA was applied to each spectral interval. CDA was performed on the extracted components to identify the factors maximizing the differences among plants fertilised with increasing N rates. Within the intervals of green, yellow and red only the first principal component (PC had an eigenvalue greater than 1 and explained more than 95% of total variance; within the ranges of red-edge and NIR, the first two PCs had an eigenvalue higher than 1. Two canonical variables explained cumulatively more than 81% of total variance and the first was able to discriminate wheat plants differently fertilised, as confirmed also by the significant correlation with aboveground biomass and grain yield parameters. The combined

Deconstructing doctoral dissertations: how many papers does it take to make a PhD?

Science.gov (United States)

Hagen, Nils T

2010-11-01

A collection of coauthored papers is the new norm for doctoral dissertations in the natural and biomedical sciences, yet there is no consensus on how to partition authorship credit between PhD candidates and their coauthors. Guidelines for PhD programs vary but tend to specify only a suggested range for the number of papers to be submitted for evaluation, sometimes supplemented with a requirement for the PhD candidate to be the principal author on the majority of submitted papers. Here I use harmonic counting to quantify the actual amount of authorship credit attributable to individual PhD graduates from two Scandinavian universities in 2008. Harmonic counting corrects for the inherent inflationary and equalizing biases of routine counting methods, thereby allowing the bibliometrically identifiable amount of authorship credit in approved dissertations to be analyzed with unprecedented accuracy. Unbiased partitioning of authorship credit between graduates and their coauthors provides a post hoc bibliometric measure of current PhD requirements, and sets a de facto baseline for the requisite scientific productivity of these contemporary PhD's at a median value of approximately 1.6 undivided papers per dissertation. Comparison with previous census data suggests that the baseline has shifted over the past two decades as a result of a decrease in the number of submitted papers per candidate and an increase in the number of coauthors per paper. A simple solution to this shifting baseline syndrome would be to benchmark the amount of unbiased authorship credit deemed necessary for successful completion of a specific PhD program, and then monitor for departures from this level over time. Harmonic partitioning of authorship credit also facilitates cross-disciplinary and inter-institutional analysis of the scientific output from different PhD programs. Juxtaposing bibliometric benchmarks with current baselines may thus assist the development of harmonized guidelines and

Resonant Homoclinic Flips Bifurcation in Principal Eigendirections

Directory of Open Access Journals (Sweden)

Tiansi Zhang

2013-01-01

Full Text Available A codimension-4 homoclinic bifurcation with one orbit flip and one inclination flip at principal eigenvalue direction resonance is considered. By introducing a local active coordinate system in some small neighborhood of homoclinic orbit, we get the Poincaré return map and the bifurcation equation. A detailed investigation produces the number and the existence of 1-homoclinic orbit, 1-periodic orbit, and double 1-periodic orbits. We also locate their bifurcation surfaces in certain regions.

Pintér, András

2015-08-01

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

2012-01-01

We describe a reduction process for symplectic principal R-bundles in the presence of a momentum map. These types of structures play an important role in the geometric formulation of non-autonomous Hamiltonian systems. We apply this procedure to the standard symplectic principal R-bundle associated with a fibration π:M→R. Moreover, we show a reduction process for non-autonomous Hamiltonian systems on symplectic principal R-bundles. We apply these reduction processes to several examples. (paper)

Principal minors and rhombus tilings

International Nuclear Information System (INIS)

Kenyon, Richard; Pemantle, Robin

2014-01-01

The algebraic relations between the principal minors of a generic n × n matrix are somewhat mysterious, see e.g. Lin and Sturmfels (2009 J. Algebra 322 4121–31). We show, however, that by adding in certain almost principal minors, the ideal of relations is generated by translations of a single relation, the so-called hexahedron relation, which is a composition of six cluster mutations. We give in particular a Laurent-polynomial parameterization of the space of n × n matrices, whose parameters consist of certain principal and almost principal minors. The parameters naturally live on vertices and faces of the tiles in a rhombus tiling of a convex 2n-gon. A matrix is associated to an equivalence class of tilings, all related to each other by Yang–Baxter-like transformations. By specializing the initial data we can similarly parameterize the space of Hermitian symmetric matrices over R,C or H the quaternions. Moreover by further specialization we can parametrize the space of positive definite matrices over these rings. This article is part of a special issue of Journal of Physics A: Mathematical and Theoretical devoted to ‘Cluster algebras mathematical physics’. (paper)

Full Text Available The article analyses co-authorship and co-citation networks in Food Policy, which is the most important agricultural policy journal in the field of agricultural economics. The paper highlights the principal researchers in this field together with their authorship and citation networks on the basis of 714 articles written between 2006 and 2015. Results suggest that the majority of the articles were written by a small number of researchers, indicating that groups and central authors play an important role in scientific advances. It also turns out that the number of articles and the central role played in the network are not related, contrary to expectations. Results also suggest that groups cite themselves more often than average, thereby boosting the scientific advancement of their own members.

Principals are school leaders who experienced stress while leading their schools towards excellence. However, principals stress experiences are always ignored and least studied. This mixed-methods study investigates primary principals' stress experiences and their Islamic coping strategies used in incapacitating the stress experiences. A total of 216 Muslim primary principals across different gender, types of schools and years of experiences as school leaders responded to the administrative stress and the Islamic coping strategies items. In addition, seven primary principals were purposefully selected and interviewed in exploring their reasons of using Islamic coping strategies for their relieving process. Results discovered that primary principals experienced fairly stress level and they perceived managing students' academic achievement was the most stressor followed by managing teachers' capabilities. Although findings revealed that no significant differences in terms primary principals' demographics; male primary principals, and experienced between 6 and 10 years and positioned in schools with least students (SLS) category have slightly higher level of stress. In terms of Islamic coping strategies used by primary principals, saying dhua to Allah, performing dhikir and reciting the Yassen are selected coping approaches employed in handling their stress. From interviews, primary principals also revealed that they used Islamic religious approaches as part of meaningful activities not just to overcoming their stress but also as part of religious approaches in remembering Allah, thinking back their past mistakes as part of the Muhasabah process. Therefore, we believed that religious approaches should be taken into consideration in principals' training as it provides peaceful and treatment in managing principals' stress issue.

Principal-vector-directed fringe-tracking technique.

Science.gov (United States)

Zhang, Zhihui; Guo, Hongwei

2014-11-01

Fringe tracking is one of the most straightforward techniques for analyzing a single fringe pattern. This work presents a principal-vector-directed fringe-tracking technique. It uses Gaussian derivatives for estimating fringe gradients and uses hysteresis thresholding for segmenting singular points, thus improving the principal component analysis method. Using it allows us to estimate the principal vectors of fringes from a pattern with high noise. The fringe-tracking procedure is directed by these principal vectors, so that erroneous results induced by noise and other error-inducing factors are avoided. At the same time, the singular point regions of the fringe pattern are identified automatically. Using them allows us to determine paths through which the "seed" point for each fringe skeleton is easy to find, thus alleviating the computational burden in processing the fringe pattern. The results of a numerical simulation and experiment demonstrate this method to be valid.

2013-01-01

Purpose: Publication analysis has value in evaluating the mechanics of academic efforts in specific scientific communities. The specific aim of this study was to evaluate whether established bibliometric patterns seen in other academic fields were likewise observed in radiation oncology publication parameters. Methods and Materials: We used a commercial bibliographic database to analyze all publications in Red Journal, or International Journal of Radiation Oncology Biology Physics (IJROBP), the New England Journal of Medicine (NEJM), the Journal of Clinical Oncology (JCO), and Radiology (Rad) between January 1, 1975 and May 18, 2011. Power-law (Lotka's law or 1/n 2 ) conformance was assessed. Curve fit analysis was then performed. Results: In all 4 journals, a total of 219,476 authors were responsible for 62,232 articles. Of those, 79,810 authors published 13,772 articles in IJROBP, with 79,446/16,707 authors/articles in NEJM, 106,984/11,920 authors/articles in JCO and 90,325/19,745 authors/articles in Rad. The mean ± standard deviation of authors per publication was 5.74 ± 4.61 overall. There were 5.8 ± 3.53, 4.8 ± 5.7, 8.9 ± 3.53, and 4.6 ± 2.8 authors per article in IJROBP, NEJM, JCO, and Rad, respectively (P 2.02 of those publishing 1 article in IJROBP, 1/n 2.52 in NEJM, 1/n 1.97 in JCO, and 1/n 2.16 in Rad. Conclusions: Bibliometric analysis shows that authorship distributions in IJROBP approximate those of the scientific literature in comparable scientific journals. Our results suggest that the majority of publications in the field of radiation oncology are produced by a small but highly productive group of authors.

Co-authoring History: Montpellier, the Vendée, and the Co-authorship of the Sources

Directory of Open Access Journals (Sweden)

István M. Szijártó

2013-10-01

Full Text Available The discourses of literature and history are generally regarded as two distinct genres. This essay sets out to investigate the use of fictitious, that is, the invented, as well as real elements, in addition to narrative tools in some literary and historical texts to examine whether there is evidence for a fundamental difference between them in this respect. In the first half of the article, from the juxtaposition of Merle’s historical novel, En nos vertes années, to Le Roy Ladurie’s The Beggar and the Professor, we shall see that real and fictitious elements are also interwoven in Merle’s text, just as history uses fictitious elements, necessarily and tacitly, or, in some works, in a rather provocative way. In the second half of this essay, in examining literary and historical narratives of the counter-revolution in the Vendée, it will become evident that historians also use the same narrative techniques as writers to orientate readers. While these findings would confound the normative distinction between history and literature, we cannot, however, finally conclude that there is no fundamental difference between literary fiction and history. Arguing against Alun Munslow, who claims in Authoring the Past that “’doing history’ is an authorial activity,” this present article tries to argue that, while in many aspects writing history is indistinguishable from writing fiction, the historian has co-authors: the sources themselves may enter the process of writing history. This is a conclusion that emerges from the analysis of Simon Schama’s Citizens. His text about the revolt in the Vendée points to a potential advantage of history when compared to literary fiction: historians may feel obliged to change their original point of view under the burden of the fact they themselves have enumerated—something we can call the latent but inherent co-authorship of the sources in historical narratives.

Sparse principal component analysis in medical shape modeling

Sjöstrand, Karl; Stegmann, Mikkel B.; Larsen, Rasmus

2006-03-01

Principal component analysis (PCA) is a widely used tool in medical image analysis for data reduction, model building, and data understanding and exploration. While PCA is a holistic approach where each new variable is a linear combination of all original variables, sparse PCA (SPCA) aims at producing easily interpreted models through sparse loadings, i.e. each new variable is a linear combination of a subset of the original variables. One of the aims of using SPCA is the possible separation of the results into isolated and easily identifiable effects. This article introduces SPCA for shape analysis in medicine. Results for three different data sets are given in relation to standard PCA and sparse PCA by simple thresholding of small loadings. Focus is on a recent algorithm for computing sparse principal components, but a review of other approaches is supplied as well. The SPCA algorithm has been implemented using Matlab and is available for download. The general behavior of the algorithm is investigated, and strengths and weaknesses are discussed. The original report on the SPCA algorithm argues that the ordering of modes is not an issue. We disagree on this point and propose several approaches to establish sensible orderings. A method that orders modes by decreasing variance and maximizes the sum of variances for all modes is presented and investigated in detail.

To sustain the critical progress made, prioritization and a multidisciplinary approach to malaria research remain important to the national malaria control program in Benin. To document the structure of the malaria collaborative research in Benin, we analyze authorship of the scientific documents published on malaria from Benin. We collected bibliographic data from the Web Of Science on malaria research in Benin from January 1996 to December 2016. From the collected data, a mulitigraph co-authorship network with authors representing vertices was generated. An edge was drawn between two authors when they co-author a paper. We computed vertex degree, betweenness, closeness, and eigenvectors among others to identify prolific authors. We further assess the weak points and how information flow in the network. Finally, we perform a hierarchical clustering analysis, and Monte-Carlo simulations. Overall, 427 publications were included in this study. The generated network contained 1792 authors and 116,388 parallel edges which converted in a weighted graph of 1792 vertices and 95,787 edges. Our results suggested that prolific authors with higher degrees tend to collaborate more. The hierarchical clustering revealed 23 clusters, seven of which form a giant component containing 94% of all the vertices in the network. This giant component has all the characteristics of a small-world network with a small shortest path distance between pairs of three, a diameter of 10 and a high clustering coefficient of 0.964. However, Monte-Carlo simulations suggested our observed network is an unusual type of small-world network. Sixteen vertices were identified as weak articulation points within the network. The malaria research collaboration network in Benin is a complex network that seems to display the characteristics of a small-world network. This research reveals the presence of closed research groups where collaborative research likely happens only between members. Interdisciplinary

2003-01-01

Research programmes appear to represent one of the more powerful instruments through which research funders (principals) steer and shape what researchers (agents) do. The fact that agents navigate between different sources and styles of programme funding and that they use programmes to their own ends is readily accommodated within principal-agent theory with the help of concepts such as shirking and defection. Taking a different route, I use three examples of research programming (by the UK, ...

The influence of iliotibial band syndrome history on running biomechanics examined via principal components analysis.

Science.gov (United States)

Foch, Eric; Milner, Clare E

2014-01-03

Iliotibial band syndrome (ITBS) is a common knee overuse injury among female runners. Atypical discrete trunk and lower extremity biomechanics during running may be associated with the etiology of ITBS. Examining discrete data points limits the interpretation of a waveform to a single value. Characterizing entire kinematic and kinetic waveforms may provide additional insight into biomechanical factors associated with ITBS. Therefore, the purpose of this cross-sectional investigation was to determine whether female runners with previous ITBS exhibited differences in kinematics and kinetics compared to controls using a principal components analysis (PCA) approach. Forty participants comprised two groups: previous ITBS and controls. Principal component scores were retained for the first three principal components and were analyzed using independent t-tests. The retained principal components accounted for 93-99% of the total variance within each waveform. Runners with previous ITBS exhibited low principal component one scores for frontal plane hip angle. Principal component one accounted for the overall magnitude in hip adduction which indicated that runners with previous ITBS assumed less hip adduction throughout stance. No differences in the remaining retained principal component scores for the waveforms were detected among groups. A smaller hip adduction angle throughout the stance phase of running may be a compensatory strategy to limit iliotibial band strain. This running strategy may have persisted after ITBS symptoms subsided. © 2013 Published by Elsevier Ltd.

Promoting principals' managerial involvement in instructional improvement.

Science.gov (United States)

Gillat, A

1994-01-01

Studies of school leadership suggest that visiting classrooms, emphasizing achievement and training, and supporting teachers are important indicators of the effectiveness of school principals. The utility of a behavior-analytic program to support the enhancement of these behaviors in 2 school principals and the impact of their involvement upon teachers' and students' performances in three classes were examined in two experiments, one at an elementary school and another at a secondary school. Treatment conditions consisted of helping the principal or teacher to schedule his or her time and to use goal setting, feedback, and praise. A withdrawal design (Experiment 1) and a multiple baseline across classrooms (Experiment 2) showed that the principal's and teacher's rates of praise, feedback, and goal setting increased during the intervention, and were associated with improvements in the academic performance of the students. In the future, school psychologists might analyze the impact of involving themselves in supporting the principal's involvement in improving students' and teachers' performances or in playing a similar leadership role themselves.

Stepping stones: Principal career paths and school outcomes.

Science.gov (United States)

Béteille, Tara; Kalogrides, Demetra; Loeb, Susanna

2012-07-01

More than one out of every five principals leaves their school each year. In some cases, these career changes are driven by the choices of district leadership. In other cases, principals initiate the move, often demonstrating preferences to work in schools with higher achieving students from more advantaged socioeconomic backgrounds. Principals often use schools with many poor or low-achieving students as stepping stones to what they view as more desirable assignments. We use longitudinal data from one large urban school district to study the relationship between principal turnover and school outcomes. We find that principal turnover is, on average, detrimental to school performance. Frequent turnover of school leadership results in lower teacher retention and lower student achievement gains. Leadership changes are particularly harmful for high poverty schools, low-achieving schools, and schools with many inexperienced teachers. These schools not only suffer from high rates of principal turnover but are also unable to attract experienced successors. The negative effect of leadership changes can be mitigated when vacancies are filled by individuals with prior experience leading other schools. However, the majority of new principals in high poverty and low-performing schools lack prior leadership experience and leave when more attractive positions become available in other schools.

Kamohelo Nthebe

2016-08-01

Full Text Available Orientation: School principals have an important role to play in the quality of service delivery in schools. Evidence suggests that school principals are generally poorly compensated, which has an adverse impact on their well-being and subsequent service quality orientation. Research purpose: This study investigated whether rewards are a predictor of well-being and service orientation of school principals in the North-West province. Motivation for the study: Effective school principals are fundamental to the success of any school, which necessitates the establishment of an effective reward and remuneration system. Research design, approach and method: Quantitative research was carried out among school principals (N = 155 in four districts of the North-West province. The Total Rewards Scale, Maslach’s Burnout Inventory – General Survey, the Utrecht Work Engagement Scale and the SERVQUAL measure were administered among the principals. Main findings: The results showed that rewards are a significant predictor of the well-being and service quality of school principals. The results further showed that burnout significantly reduces the service quality of school principals. No significant relationships were found between work engagement and the service quality of school principals. Practical/managerial implications: An effective total rewards system enhances the well-being of school principals and, subsequently, their willingness and commitment to delivering quality services. Contribution: The results of this study point out some key elements that need to be considered by the Department of Education to enable quality service delivery in South African schools.

EXPLORING THE IMPACT OF APPLICANTS’ GENDER AND RELIGION ON PRINCIPALS’ SCREENING DECISIONS FOR ASSISTANT PRINCIPAL APPLICANTS

Directory of Open Access Journals (Sweden)

SUSAN C. BON

2009-02-01

Full Text Available In this experimental study, a national random sample of high school principals (stratified by gender were asked to evaluate hypothetical applicants whose resumes varied by religion (Jewish, Catholic, nondenominational and gender (male, female for employment as assistant principals. Results reveal that male principals rate all applicants higher than female principals and that the gender and religion of applicants failed to negatively or positively affect principals’ evaluations. These results suggest that discrimination based on an applicant’s gender and religion failed to be manifested during the pre-interview stage of the selection process. The paper concludes with a theoretical discussion of the distinction between explicit and implicit prejudice, and encourages future researchers to investigate the potential impact of prejudice on employment selection decisions and to consider whether schools should promote diversity in leadership positions.

2003-06-15

In this study, acoustic emission (AE) signals due to surface cracking and moisture movement in the flat-sawn boards of oak (Quercus Variablilis) during drying under the ambient conditions were analyzed and classified using the principal component analysis. The AE signals corresponding to surface cracking showed higher in peak amplitude and peak frequency, and shorter in rise time than those corresponding to moisture movement. To reduce the multicollinearity among AE features and to extract the significant AE parameters, correlation analysis was performed. Over 99% of the variance of AE parameters could be accounted for by the first to the fourth principal components. The classification feasibility and success rate were investigated in terms of two statistical classifiers having six independent variables (AE parameters) and six principal components. As a result, the statistical classifier having AE parameters showed the success rate of 70.0%. The statistical classifier having principal components showed the success rate of 87.5% which was considerably than that of the statistical classifier having AE parameters

We provide unified phenomenological description of magnetooptic effects being linear and quadratic in magnetization. The description is based on few principal spectra, describing elements of permittivity tensor up to the second order in magnetization. Each permittivity tensor element for any magnetization direction and any sample surface orientation is simply determined by weighted summation of the principal spectra, where weights are given by crystallographic and magnetization orientations. The number of principal spectra depends on the symmetry of the crystal. In cubic crystals owning point symmetry we need only four principal spectra. Here, the principal spectra are expressed by ab initio calculations for bcc Fe, fcc Co and fcc Ni in optical range as well as in hard and soft x-ray energy range, i.e. at the 2p- and 3p-edges. We also express principal spectra analytically using modified Kubo formula.

An evaluation capacity building toolkit for principal investigators of undergraduate research experiences: A demonstration of transforming theory into practice.

Science.gov (United States)

Rorrer, Audrey S

2016-04-01

This paper describes the approach and process undertaken to develop evaluation capacity among the leaders of a federally funded undergraduate research program. An evaluation toolkit was developed for Computer and Information Sciences and Engineering(1) Research Experiences for Undergraduates(2) (CISE REU) programs to address the ongoing need for evaluation capacity among principal investigators who manage program evaluation. The toolkit was the result of collaboration within the CISE REU community with the purpose being to provide targeted instructional resources and tools for quality program evaluation. Challenges were to balance the desire for standardized assessment with the responsibility to account for individual program contexts. Toolkit contents included instructional materials about evaluation practice, a standardized applicant management tool, and a modulated outcomes measure. Resulting benefits from toolkit deployment were having cost effective, sustainable evaluation tools, a community evaluation forum, and aggregate measurement of key program outcomes for the national program. Lessons learned included the imperative of understanding the evaluation context, engaging stakeholders, and building stakeholder trust. Results from project measures are presented along with a discussion of guidelines for facilitating evaluation capacity building that will serve a variety of contexts. Copyright © 2016.

Lammers, Richard; Simunich, Thomas; Ashurst, John

2016-05-01

With the recent merger of the American Osteopathic Association (AOA) and the Accreditation Council for Graduate Medical Education (ACGME) a heightened pressure for publication may become evident. Our objective was to determine whether there was a gap in the type of both medical degree designation and advanced degree designation among authorship in three United States-based academic emergency medicine journals. We reviewed the Journal of Emergency Medicine, Academic Emergency Medicine and Annals of Emergency Medicine for the type of degree designation that the first and senior authors had obtained for the years 1995, 2000, 2005, 2010 and 2014. A total of 2.48% of all authors held a degree in osteopathic medicine. Osteopathic physician first authors contributed to 3.26% of all publications while osteopathic physician senior authors contributed 1.53%. No statistical trend could be established for the years studied for osteopathic physicians. However, we noted an overall trend for increased publication for allopathic senior authors (p=0.001), allopathic first authors with a dual degree (p=0.003) and allopathic senior authors with a dual degree (p=0.005). For each journal studied, no statistical trend could be established for osteopathic first or senior authors but a trend was noted for allopathic first and senior authors in the Journal of Emergency Medicine (p-value=0.020 and 0.006). Of those with dual degrees, osteopathic physicians were in the minority with 1.85% of osteopathic first authors and 0.60% of osteopathic senior authors attaining a dual degree. No statistical trend could be established for increased dual degree publications for osteopathic physicians over the study period, nor could a statistical trend be established for any of the journals studied. Very few osteopathic physicians have published in the Journal of Emergency Medicine, Academic Emergency Medicine or Annals of Emergency Medicine over the last two decades. Despite a trend for increased

Between Authorship and Oral Transmission: Negotiating the Attribution of Authorial, Oral and Collective Style Markers in Early Modern Playtexts

Directory of Open Access Journals (Sweden)

Lene Buhl Petersen

2016-03-01

Full Text Available The production of playtexts in early modern England falls between two categories of artistic provenance: textual production in quill and print and oral transmission of the text committed to paper. Both categories are rightly speaking processes, and may be repeated several times over within the lifespan of a play. The former is the domain of authors, scribes and printers, the latter the responsibility of actors using their memories to verbally transmit the play in performance. An early modern playtext may thus be (cowritten, probably performed and potentially printed, and possibly rewritten, reperformed and reprinted in almost any given combination. It is only to be expected that a number of stylistic ‘complications’ will ensue. The question remains how to determine which stylistic markers characterise which creative domain. This paper returns to the cross-roads between authorship attribution and the quantification of other (oral, collective style markers in an attempt to offer discussion and a better overview of appropriate methodologies for determining which features may feasibly be attributed to which source(s.

Honouring Roles: The Story of a Principal and a Student

Directory of Open Access Journals (Sweden)

Jerome Cranston

2012-11-01

Full Text Available The importance of the teacher-student relationship in educational practice is well established, as is the idea of principal leadership in relationship to staff. Even though principal leadership is regarded as a factor in student success, the principal’s effect is usually assumed to take place via the teaching staff. There is an absence of research about the “lived experience” of direct principal-student relationships that shed lights on the ways in which these relationships play a role in student success and principal transformation. This paper presents two narratives written about a particular set of principal-student interactions experienced by the researcher (principal and participant (student.  The analysis uses a narrative inquiry approach to explore both the individual and collective meanings of this principal-student relationship. The stories and their derived meanings have the potential to enliven and  influence educational practice as they explore the subtleties of the principal-student relationship.

Exploring functional data analysis and wavelet principal component analysis on ecstasy (MDMA wastewater data

Directory of Open Access Journals (Sweden)

Stefania Salvatore

2016-07-01

Full Text Available Abstract Background Wastewater-based epidemiology (WBE is a novel approach in drug use epidemiology which aims to monitor the extent of use of various drugs in a community. In this study, we investigate functional principal component analysis (FPCA as a tool for analysing WBE data and compare it to traditional principal component analysis (PCA and to wavelet principal component analysis (WPCA which is more flexible temporally. Methods We analysed temporal wastewater data from 42 European cities collected daily over one week in March 2013. The main temporal features of ecstasy (MDMA were extracted using FPCA using both Fourier and B-spline basis functions with three different smoothing parameters, along with PCA and WPCA with different mother wavelets and shrinkage rules. The stability of FPCA was explored through bootstrapping and analysis of sensitivity to missing data. Results The first three principal components (PCs, functional principal components (FPCs and wavelet principal components (WPCs explained 87.5-99.6 % of the temporal variation between cities, depending on the choice of basis and smoothing. The extracted temporal features from PCA, FPCA and WPCA were consistent. FPCA using Fourier basis and common-optimal smoothing was the most stable and least sensitive to missing data. Conclusion FPCA is a flexible and analytically tractable method for analysing temporal changes in wastewater data, and is robust to missing data. WPCA did not reveal any rapid temporal changes in the data not captured by FPCA. Overall the results suggest FPCA with Fourier basis functions and common-optimal smoothing parameter as the most accurate approach when analysing WBE data.

Full Text Available The purpose of this study was to investigate secondary school principals’ perceptions of multicultural education in a rural southeastern state. The researchers wanted to ascertain whether or not the race or gender of school principals have a role in how those principals view multicultural education in theory (its theoretical value. For the purpose of this study, multicultural education in theory was defined as the belief that multicultural education is for all students, elevates students’ self-esteem, is embedded in cultural pluralism, and recognizes the social, political, and economic community and societal constructs on students of color (Fernandez, 1996. Three hundred and two secondary school principals were surveyed in a designated southeastern state. A significant difference was discovered with regard to the gender of the school principals and their perceptions of the theoretical value of multicultural education.

3D face recognition with asymptotic cones based principal curvatures

KAUST Repository

Tang, Yinhang

2015-05-01

The classical curvatures of smooth surfaces (Gaussian, mean and principal curvatures) have been widely used in 3D face recognition (FR). However, facial surfaces resulting from 3D sensors are discrete meshes. In this paper, we present a general framework and define three principal curvatures on discrete surfaces for the purpose of 3D FR. These principal curvatures are derived from the construction of asymptotic cones associated to any Borel subset of the discrete surface. They describe the local geometry of the underlying mesh. First two of them correspond to the classical principal curvatures in the smooth case. We isolate the third principal curvature that carries out meaningful geometric shape information. The three principal curvatures in different Borel subsets scales give multi-scale local facial surface descriptors. We combine the proposed principal curvatures with the LNP-based facial descriptor and SRC for recognition. The identification and verification experiments demonstrate the practicability and accuracy of the third principal curvature and the fusion of multi-scale Borel subset descriptors on 3D face from FRGC v2.0.

Full Text Available This study investigates variability of tomato genotypes based on morphological and biochemical fruit traits. Experimental material is a part of tomato genetic collection from Institute of Filed and Vegetable Crops in Novi Sad, Serbia. Genotypes were analyzed for fruit mass, locule number, index of fruit shape, fruit colour, dry matter content, total sugars, total acidity, lycopene and vitamin C. Minimum, maximum and average values and main indicators of variability (CV and σ were calculated. Principal component analysis was performed to determinate variability source structure. Four principal components, which contribute 93.75% of the total variability, were selected for analysis. The first principal component is defined by vitamin C, locule number and index of fruit shape. The second component is determined by dry matter content, and total acidity, the third by lycopene, fruit mass and fruit colour. Total sugars had the greatest part in the fourth component.

Principal bundles the classical case

Sontz, Stephen Bruce

2015-01-01

This introductory graduate level text provides a relatively quick path to a special topic in classical differential geometry: principal bundles.  While the topic of principal bundles in differential geometry has become classic, even standard, material in the modern graduate mathematics curriculum, the unique approach taken in this text presents the material in a way that is intuitive for both students of mathematics and of physics. The goal of this book is to present important, modern geometric ideas in a form readily accessible to students and researchers in both the physics and mathematics communities, providing each with an understanding and appreciation of the language and ideas of the other.

BINABITROP is a bibliographical database of more than 38000 records about the ecosystems and organisms of Costa Rica. In contrast with commercial databases, such as Web of Knowledge and Scopus, which exclude most of the scientific journals published in tropical countries, BINABITROP is a comprehensive record of knowledge on the tropical ecosystems and organisms of Costa Rica. We analyzed its contents in three sites (La Selva, Palo Verde and Las Cruces) and recorded scientific field, taxonomic group and authorship. We found that most records dealt with ecology and systematics, and that most authors published only one article in the study period (1963-2011). Most research was published in four journals: Biotropica, Revista de Biología Tropical/ International Journal of Tropical Biology and Conservation, Zootaxa and Brenesia. This may be the first study of a such a comprehensive database for any case of tropical biology literature.

Multilevel sparse functional principal component analysis.

Science.gov (United States)

Di, Chongzhi; Crainiceanu, Ciprian M; Jank, Wolfgang S

2014-01-29

We consider analysis of sparsely sampled multilevel functional data, where the basic observational unit is a function and data have a natural hierarchy of basic units. An example is when functions are recorded at multiple visits for each subject. Multilevel functional principal component analysis (MFPCA; Di et al. 2009) was proposed for such data when functions are densely recorded. Here we consider the case when functions are sparsely sampled and may contain only a few observations per function. We exploit the multilevel structure of covariance operators and achieve data reduction by principal component decompositions at both between and within subject levels. We address inherent methodological differences in the sparse sampling context to: 1) estimate the covariance operators; 2) estimate the functional principal component scores; 3) predict the underlying curves. Through simulations the proposed method is able to discover dominating modes of variations and reconstruct underlying curves well even in sparse settings. Our approach is illustrated by two applications, the Sleep Heart Health Study and eBay auctions.

Principals, Trust, and Cultivating Vibrant Schools

Directory of Open Access Journals (Sweden)

Megan Tschannen-Moran

2015-03-01

Full Text Available Although principals are ultimately held accountable to student learning in their buildings, the most consistent research results have suggested that their impact on student achievement is largely indirect. Leithwood, Patten, and Jantzi proposed four paths through which this indirect influence would flow, and the purpose of this special issue is to examine in greater depth these mediating variables. Among mediating variables, we assert that trust is key. In this paper, we explore the evidence that points to the role that faculty trust in the principal plays in student learning and how principals can cultivate trust by attending to the five facets of trust, as well as the correlates of trust that mediate student learning, including academic press, collective teacher efficacy, and teacher professionalism. We argue that trust plays a role in each of the four paths identified by Leithwood, Patten, and Jantzi. Finally, we explore possible new directions for future research.

Dynamic of consumer groups and response of commodity markets by principal component analysis

Science.gov (United States)

Nobi, Ashadun; Alam, Shafiqul; Lee, Jae Woo

2017-09-01

This study investigates financial states and group dynamics by applying principal component analysis to the cross-correlation coefficients of the daily returns of commodity futures. The eigenvalues of the cross-correlation matrix in the 6-month timeframe displays similar values during 2010-2011, but decline following 2012. A sharp drop in eigenvalue implies the significant change of the market state. Three commodity sectors, energy, metals and agriculture, are projected into two dimensional spaces consisting of two principal components (PC). We observe that they form three distinct clusters in relation to various sectors. However, commodities with distinct features have intermingled with one another and scattered during severe crises, such as the European sovereign debt crises. We observe the notable change of the position of two dimensional spaces of groups during financial crises. By considering the first principal component (PC1) within the 6-month moving timeframe, we observe that commodities of the same group change states in a similar pattern, and the change of states of one group can be used as a warning for other group.

Incremental Tensor Principal Component Analysis for Handwritten Digit Recognition

Directory of Open Access Journals (Sweden)

Chang Liu

2014-01-01

Full Text Available To overcome the shortcomings of traditional dimensionality reduction algorithms, incremental tensor principal component analysis (ITPCA based on updated-SVD technique algorithm is proposed in this paper. This paper proves the relationship between PCA, 2DPCA, MPCA, and the graph embedding framework theoretically and derives the incremental learning procedure to add single sample and multiple samples in detail. The experiments on handwritten digit recognition have demonstrated that ITPCA has achieved better recognition performance than that of vector-based principal component analysis (PCA, incremental principal component analysis (IPCA, and multilinear principal component analysis (MPCA algorithms. At the same time, ITPCA also has lower time and space complexity.

Full Text Available One of the fundamental concerns in education is the management and the improvement of principals and teachers’ performance where selecting intelligent and capable managers can help solve many of present challenges and problems. Various researches conducted so far indicate that commonly the effective principals enjoy some of the essential multiple intelligences. In the present study, the relationship between the three types of Maneh & Semelqan high school principals and teachers’ intelligences, namely, intrapersonal intelligence, interpersonal intelligence, and verbal/linguistic intelligence and the strategic thinking skills was investigated. The research method was descriptive-correlational and the population consisted of 200 subjects of whom 127 were randomly selected. After assigning the subjects to the investigation, 127 questionnaires were distributed among them. Two standard questionnaires of multiple intelligences and strategic thinking skills were administered where Cronbach’s Alpha for the multiple intelligences was 0.893 and that of the strategic thinking skills was 0.944. To analyze the data, the researchers used the SPSS19 package and the EXCELL2013. The frequency distribution tabulation was organized by using descriptive statistics and the Pearson correlation test was based on the inferential statistics employed in the present study. At the end, the findings of study indicated that there was a significant relationship between high school principals and teachers’ multiple intelligences and their strategic thinking skills.

Informing principal policy reforms in South Africa through data-based evidence

Directory of Open Access Journals (Sweden)

Gabrielle Wills

2015-12-01

Full Text Available In the past decade there has been a notable shift in South African education policy that raises the value of school leadership as a lever for learning improvements. Despite a growing discourse on school leadership, there has been a lack of empirical based evidence on principals to inform, validate or debate the efficacy of proposed policies in raising the calibre of school principals. Drawing on findings from a larger study to understand the labour market for school principals in South Africa, this paper highlights four overarching characteristics of this market with implications for informing principal policy reforms. The paper notes that improving the design and implementation of policies guiding the appointment process for principals is a matter of urgency. A substantial and increasing number of principal replacements are taking place across South African schools given a rising age profile of school principals. In a context of low levels of principal mobility and high tenure, the leadership trajectory of the average school is established for nearly a decade with each principal replacement. Evidence-based policy making has a strong role to play in getting this right.

Getting from Here to There: The Roles of Policy Makers and Principals in Increasing Science Teacher Quality

Science.gov (United States)

Shen, Ji; Gerard, Libby; Bowyer, Jane

2010-04-01

In this study we investigate how federal and state policy makers, and school principals are working to improve science teacher quality. Interviews, focused discussions, and policy documents serve as the primary data source. Findings suggest that both policy makers and principals prioritize increasing incentives for teachers entering the science teaching profession, providing professional development for new teachers, and using students’ data to evaluate and improve instruction. Differences between the two leadership groups emerged in terms of the grain size and practicality of their concerns. Our findings indicate that the complexity of educational challenges to improve science teacher quality call for the co-construction of policy by multiple constituent groups including school principals, federal and state policy makers, and science education researchers.
