Selected AbstractsConcerns About Authorship and Bias in Scientific PublicationsJOURNAL OF CLINICAL HYPERTENSION, Issue 9 2006Marvin Moser MD Editor in Chief No abstract is available for this article. [source] The Ethical Assignment of Authorship in Scientific Publications: Issues and GuidelinesACADEMIC EMERGENCY MEDICINE, Issue 10 2008V. Ramana Feeser MD Abstract Properly assigning authorship of academic papers is often an ethical challenge. Through a hypothetical case study, the authors examine some of the potential ethical issues involved in determining who should and should not be listed as an author: the problems of honorary authorship, coerced authorship, and ghost authorship, as well as the question of how to order authors. Guidelines for avoiding and negotiating these issues are also discussed.

[source] Is my antibody-staining specific?EUROPEAN JOURNAL OF NEUROSCIENCE, Issue 12 2008How to deal with pitfalls of immunohistochemistry Abstract Immunohistochemistry is a sensitive and versatile method widely used to investigate the cyto- and chemoarchitecture of the brain. It is based on the high affinity and selectivity of antibodies for a single epitope. However, it is now recognized that the specificity of antibodies needs to be tested in control experiments to avoid false-positive results due to non-specific binding to tissue components or recognition of epitopes shared by several molecules. This ,Technical Spotlight' discusses other pitfalls, which are often overlooked, although they can strongly influence the outcome of immunohistochemical experiments. It also recapitulates the minimal set of information that should be provided in scientific publications to allow proper evaluation and replication of immunohistochemical experiments. In particular, tissue fixation and processing can have a strong impact on antigenicity by producing conformational changes to the epitopes, limiting their accessibility (epitope masking) or generating high non-specific background. These effects are illustrated for an immunoperoxidase staining experiment with three antibodies differing in susceptibility to fixation, using tissue from mice processed under identical conditions, except for slight variations in tissue fixation. In these examples, specific immunostaining can be abolished depending on fixation strength, or detected only after prolonged postfixation. As a consequence, antibody characterization in immunohistochemistry should include their susceptibility towards fixation and determination of the optimal conditions for their use. [source] Whither Latin America? trends and challenges of science in Latin AmericaIUBMB LIFE, Issue 4-5 2007Marcelo Hermes-Lima Abstract Science in Latin America has experienced vigorous growth in the past decade, as demonstrated by the fact that the Latin American share of the world's scientific publications increased from 1.8% in 1991 - 1995 to 3.4% in 1999 - 2003. Significant growth has also taken place in the numbers of PhDs in science and engineering (S&E) awarded in Latin American countries in recent years, including those in the natural sciences. Importantly, albeit at different rates, growth has been verified in almost all countries in the region, indicating a general effort to promote the development of S&E. In most research fields, however, the recognition or relative impact of Latin American science, as measured by the average number of citations received by published articles (CpP), is still below world averages and much lower than in developed nations. We show that average CpP values for a set of 34 representative developing and developed countries correlate significantly with gross expenditure in research and development (GERD), with gross domestic product (GDP) per capita and with the number of researchers per million inhabitants (RpM). Among those countries, Latin American nations present some of the lowest average values of CpP (<6), GERD (,1% of GDP) and RpM (<2,000). We also examined recent trends in scientific activity in Latin America, with focus on the natural sciences and on biochemistry and molecular biology (BMB). In terms of citation scores, publications in BMB compare favorably to those in other research fields within Latin America. At the same time, however, Latin American BMB is one of the areas for which relative impact - compared to developed nations or normalized to world averages - is lowest. These observations clearly indicate the need to establish effective policies to increase competitiveness in terms of the quality and international recognition of Latin American natural sciences in general, and BMB in particular, as opposed to merely increasing the absolute numbers of publications or the numbers of PhDs awarded in the region. IUBMB Life, 59: 199-210, 2007 [source] OPEN KNOWLEDGE DISCLOSURE: AN OVERVIEW OF THE EVIDENCE AND ECONOMIC MOTIVATIONSJOURNAL OF ECONOMIC SURVEYS, Issue 2 2007Julien Pénin Abstract This paper reviews current literature on open knowledge disclosure strategies used by firms. It is usually acknowledged that for an innovative firm that does not benefit from a natural protection (such as lead time advance) the best strategy is to keep an innovation secret as long as possible or to protect it through an exclusive patent. However, in apparent contrast to this traditional view, many studies suggest that firms often disclose important parts of their knowledge through scientific publications, conferences, the Internet, etc. This paper aims to provide an overview first of the evidence supporting the existence of open knowledge disclosure and second of the economic motivations that encourage rational, profit seeking firms to adopt these behaviours. [source] A historical review of research on the weaver ant Oecophylla in biological controlAGRICULTURAL AND FOREST ENTOMOLOGY, Issue 1 2008Paul Van Mele Abstract 1,Although the weaver ant Oecophylla is the first written record of biological control, dating from 304 ad, there have been fewer than 70 scientific publications on this predator as a biological control agent in Asia, from the early 1970s onwards, and fewer than 25 in Africa. 2,Apart from crop-specific ecological and perceptual factors, a historical review shows that political and market forces have also determined the extent to which Oecophylla was incorporated into research and development programmes. 3,In Africa, research on weaver ants in biological control concentrated on export crops, such as coconut and cocoa, whereas, in Asia and Australia, research focused on fruit and nut crops, primarily destined for domestic markets. 4,Increased evidence of pesticide inefficiency under tropical smallholder conditions, changing paradigm shifts in participatory research and a growing scientific interest in local knowledge in the early 1990s opened up new avenues for research on conservation biological control. 5,Lobbying and advocacy have been needed to ensure that Oecophylla was recognized as an effective biological control agent. 6,With an increased market demand for organic produce, holistic approaches such as conservation biological control, particularly the use of Oecophylla, are increasing in importance. 7,Multi-stakeholder strategies for collaborative learning are proposed for a better control of major fruit, nut and timber tree pests in Africa, Asia and Australia. [source] Review of the ethnobotany, chemistry, biological activity and safety of the botanical dietary supplement Morinda citrifolia (noni)*JOURNAL OF PHARMACY AND PHARMACOLOGY: AN INTERNATI ONAL JOURNAL OF PHARMACEUTICAL SCIENCE, Issue 12 2007Alison D. Pawlus Morinda citrifolia, commonly called noni, has a long history as a medicinal plant and its use as a botanical dietary supplement has grown tremendously in recent years. This has prompted a concomitant increase in research on the phytochemical constituents and biological activity of noni. A relatively large number of scientific publications on noni have been published in recent years, including a number of review articles. The goals of this review are to provide an updated categorization of the phytochemical constituents found in noni and to provide perspective for its extensive utilization as a major botanical dietary supplement. Included herein are a comprehensive list of known ethno-botanical uses and common names of M. citrifolia, a brief summary of relevant biological studies and a discussion of the safety of noni as a supplement. [source] Self-Help Groups in the Welfare State: Treatment Program or Voluntary Action?NONPROFIT MANAGEMENT & LEADERSHIP, Issue 2 2002Magnus Karlsson This article identifies two different perspectives used when studying self-help groups: the professional treatment perspective and the voluntary action perspective. An outline of the perspectives leads to a discussion of their consequences for self-help group research. The authors categorize about five hundred scientific publications from all over the world on the basis of the perspectives they present on self-help groups; the results indicate that different perspectives seem to be preferred in different countries and when discussing different subjects. Finally, the authors suggest questions and concepts that the perspectives generate, and they emphasize the importance of being aware of which perspective is used in the study of self-help groups. [source] Transatlantic innovation infrastructure networks: public-private, EU,US R&D partnershipsR & D MANAGEMENT, Issue 1 2004Elias G. Carayannis Collaborative, team-based research is now the most significant mode of activity in the global scientific community. Anecdotal and statistical evidence shows moreover that collaboration in scientific research is increasingly global in nature. That is, the groups of researchers who are involved in scientific progress often span one or more nations in origin, location and/or sponsorship. Another significant trend in recent cases of scientific collaboration is the increase in cross-sectoral cooperation, where researchers in a group are employed by government, private industry, and/or academic and other non-profit institutions. In this paper, we review the scale, scope and intensity of cross-national, cross-sectoral research collaboration through the analysis of historical data on co-authorship of scientific publications. The first part of the paper reviews existing literature on the analysis of co-authorship data, and discusses the limitations of this form of analysis and typical strategies to mitigate those limitations. The second part of the paper describes a preliminary study of cross-national, cross-sectoral scientific collaborations covering the years 1988 through 1997, where we examined the scale (volume of co-authored papers), intensity (co-authored papers versus other kinds of co-authorship), and scope (patterns in co-authorship) for cross-national, cross-sectoral collaborations. The conclusion of the paper discusses significant trends and patterns derived from this study, and their implications for further research into these types of collaborations. [source] Twenty Years of the Journal of Product Innovation Management: History, Participants, and Knowledge Stock and FlowsTHE JOURNAL OF PRODUCT INNOVATION MANAGEMENT, Issue 3 2007Wim Biemans The Journal of Product Innovation Management (JPIM) serves as a marketplace for science-based, innovative ideas that are produced and consumed by scholars and businesspeople. Now that JPIM has existed for 20 years, two intriguing questions emerge: (1) How has the journal evolved over time in terms of knowledge stock, that is, what are the characteristics of the growing stock of knowledge published by JPIM over the years; and (2) how has the journal evolved in knowledge flow, that is, how is JPIM influenced by other scientific publications and what is its impact on other journals? In terms of knowledge stock, over 35% of the articles published over the 20 years investigate processes and metrics for performance management. The next most frequently published area was strategy, planning, and decision making (20%), followed by customer and market research (17%). The dominant research method used was a cross-sectional large-sample survey, and the focus most usually is at the project level of the firm. The large majority of JPIM authors (60%) have a marketing background, with the remaining 40% representing numerous functional domains. Academics at all levels publish in JPIM, and though most authors hail from North America, the Dutch are a significant second group. JPIM was analyzed from a knowledge-flow perspective by looking at the scientific sources used by JPIM authors to develop their ideas and articles. To this end a bibliometric analysis was performed by analyzing all references in articles published in JPIM. During 1984,2003 JPIM published 488 articles, containing 10,314 references to journals and 6,533 references to other sources. Some 20% of these references (2,020) were self-references to JPIM articles. The remaining 8,294 journal references were to articles in 287 journals in the fields of management (25%), marketing (24%), and management of technology (14%). However, it should be pointed out that many domains were dominated by a limited number of journals. The second component of knowledge flow concerns the extent to which the ideas developed in JPIM are consumed by other authors. Again, bibliometric analysis was used to analyze data from the Social Sciences Citation Index (SSCI) about citations to JPIM in other journals. For the period 1984,2005, the SSCI registered 7,773 citations to JPIM in 2,067 articles published in 278 journals (including the 2,020 self-citations in JPIM). The functional areas most frequently citing JPIM are management of technology (25%), marketing (15%), management (14%), and operations management and management science (9%). Again, several domains were found to be dominated by a limited number of journals. At the level of individual journals the analysis shows a growing impact of JPIM on management of technology journals. The knowledge-flow analysis demonstrates how JPIM functions as a bridge between the knowledge from various domains and the body of knowledge on management of technology. It suggests a growing specialization of the field of technology innovation management, with JPIM being firmly entrenched as the acknowledged leading journal. [source] Sexual and Reproductive Health Knowledge in Cystic Fibrosis Female Patients and Their ParentsTHE JOURNAL OF SEXUAL MEDICINE, Issue 3 2009Aleksandra Korzeniewska MD ABSTRACT Introduction., The changing outcomes for young cystic fibrosis (CF) patients means that reproductive health issues have become an integral part of CF management. Aim., The aim of this study was to investigate the knowledge and experiences of reproductive and sexual health issues in women with CF and to investigate the knowledge and reproductive health attitudes of their parents. Main Outcome Measures., Assessment of reproductive and sexual health knowledge in female CF patients and their parents. Methods., A questionnaire study directed to 120 Polish women with CF aged 16 years and older and their parents. Results., Sixty-four patients and their parents responded to the questionnaire. Sixty-eight percent of the patients started sexual intercourse at a mean age of 19.2 years. Eighty-four percent of all sexually active women reported that they did not use any form of contraception. Only 32.8% of women understood the problems connected with their own and male fertility in CF. Popular scientific publications and other CF patients were identified as the most important source of information. Only 23% of parents understood the problems connected with female fertility in CF; 44% of parents thought that man with CF had normal fertility. Seventy-five percent of the women and 40% of the parents felt that sexual health discussions should begin between age 12 and 14 years with a CF doctor and the mother. Conclusions., Our study showed that significant knowledge gaps exist regarding fertility issues in both CF patients and CF parents. Women with CF have some general knowledge about sexual issues but insufficient knowledge to have a safe sexual life. The results helped us to develop the educational program for CF patients.

[source] Mosquito-borne disease and climate change in Australia: time for a reality checkAUSTRALIAN JOURNAL OF ENTOMOLOGY, Issue 1 2009Richard C Russell Abstract Will warming climate increase the risk or prevalence of mosquito-borne disease in Australia, as has been projected in a number of scientific publications and governmental reports? Unfortunately, most of these ,predictions' do not adequately consider the current and historical distribution of the vectors and diseases, their local ecology and epidemiology and the impact of societal features and the capacity for public health interventions in Australia. Overall, a strong case can be made that we are unlikely to see significant changes in the distribution of transmission of the exotic pathogens causing malaria and dengue, and while activity of endemic arboviruses such as Murray Valley encephalitis and Ross River viruses may possibly increase in some areas, it is likely to decrease in others. The ecologies of mosquito-borne diseases can be complex and difficult to predict, and any evaluation of potential effects of changes in climate will need a detailed examination of site-specific vector, host and other factors likely to influence the outcomes on human health. Of itself, climate change as currently projected, is not likely to provide great cause for public health concern with mosquito-borne disease in Australia. [source] Features and preliminary results of the Dutch centre of the ERSPC (Rotterdam, the Netherlands)BJU INTERNATIONAL, Issue 2003M.J. Roobol OBJECTIVE To describe the preliminary results of the Dutch section of a large multicentre study of screening for prostate cancer, the European Randomized study of Screening for Prostate Cancer (ERSPC), initiated in the Netherlands and Belgium in 1991. MATERIALS AND METHODS After a series of five pilot studies which started in 1991, full-capacity screening started in 1994 with the use of a serum prostate-specific antigen (PSA) determination, a digital rectal examination (DRE) and transrectal ultrasonography (TRUS) as screening tests. Depending on the results and the screening protocol used, men were referred for further examination by sextant biopsies (extended with a seventh biopsy if TRUS showed abnormality). The protocols used, efficiency of the different screening tests, number of cancers detected in the pilot studies, initial screening round and preliminary results of the second screening round are described. RESULTS After the pilot studies it became clear that a study of prostate cancer screening was feasible in the Rotterdam area. The screening protocol was workable and the recruitment rate acceptable (39.5%). An inventory of the population registries of Rotterdam and surrounding municipalities, and the known recruitment rate, made it clear that a contribution of 40 000 men (aged 55,74 years) from the Dutch centre to the ERSPC was feasible. The initial screening round started in December 1993 and lasted until December 1999 (protocol 5,10). In all, 42 376 men were randomized and 1014 cancers detected (5.1%). During this screening the protocol was simplified. After evaluating the different screening tests abnormal results of the DRE and TRUS were omitted as an indication for a sextant biopsy. Only a serum PSA level of , 3.0 ng/mL is now used as the indication. The second screening round started in December 1997 and continues. To December 2002, 9920 men were screened for the second time, 4 years after their initial screening visit. To date 446 cancers have been detected (4.5%); this round will last to December 2003. Further evaluation of the screening regimen and characteristics of the cancers detected are constantly assessed within the Dutch ERSPC. Meanwhile a third screening round has also been initiated, which will last to December 2007. CONCLUSION A prostate cancer screening study of the projected magnitude is feasible in Rotterdam; the recruitment rate is acceptable and the screening tests well tolerated. The study has generated many scientific publications and will be of great value in determining whether prostate cancer screening should be part of general healthcare. [source] The number of authors of scientific publicationsACTA PAEDIATRICA, Issue 5 2004Rolf Zetterström As in most other scientific journals, the number of authors per paper published in Acta Paediatrica is gradually increasing. In the 2003 volume, the number of authors was six or more in about one-third of the Regular papers and Clinical observations. The editorial board has handled several conflicts of interest due to disputes about authorship. Conclusion: Editors of scientific journals should promote a policy with the aim of creating a true balance between authorship and originality of papers. [source] | ||||||||||||||||
