Author lists should inform readers about who did a piece of research. If authorship attribution is incorrect, the wrong people may take the credit or the blame. Correct authorship of medical papers is also important because the research and publication process relies on trust. If scientists or clinicians are prepared to lie about who was involved with a research project why should we believe their findings? Groups of journal editors, notably the International Committee of Medical Journal Editors, have tried to establish criteria for authorship but these are not universally accepted. Despite the lack of agreement, authorship of journal articles continues to be the basis for academic appointments and is used to measure the research output of departments and therefore determine future funding. Some journals have started to use contributor lists, indicating the role of each individual, in place of, or in addition to, traditional lists of authors. However, problems about the threshold of involvement that merits authorship, and the order of listing remain unresolved. Journal editors are usually unable to adjudicate on authorship disputes since detailed, local knowledge is required. Institutions might therefore play a greater role in setting and enforcing authorship policies. Disputes could be reduced if authorship criteria were agreed, in writing, among all contributors at the start of a research project.  相似文献

We performed a bibliometric search covering a 1-year period to evaluate the number and the scientific weight of nuclear medicine papers published from European as compared with other countries. The scientific impact of our discipline was evaluated according to the impact factor of each publication, and we also aimed to identify those countries and topics that are making the principal contributions to the development of our discipline. To this end, a search on MEDLINE (PubMed) was run to find all peer-reviewed articles published between April 2002 and May 2003, using isotope definitions as search terms. A total of 3,292 publications were identified. Of these, 650 were of no nuclear medicine interest, 229 were reviews and 82 had no country specified. In absolute numbers, Europe leads research in nuclear medicine (939 papers, 38.9%) followed by the USA (608 papers, 25.2%). Among European countries, Germany is the nation that is currently making the greatest contribution to the scientific production of nuclear medicine in Europe. Articles concerning the use of nuclear medicine in oncology account for more than one-quarter of all published nuclear medicine papers.  相似文献

The Editors’ Network of the European Society of Cardiology (ESC) provides a dynamic forum for editorial discussions and endorses the recommendations of the International Committee of Medical Journal Editors (ICMJE) to improve the scientific quality of biomedical journals. Authorship confers credit and important academic rewards. Recently, however, the ICMJE emphasized that authorship also requires responsibility and accountability. These issues are now covered by the new (fourth) criterion for authorship. Authors should agree to be accountable and ensure that questions regarding the accuracy and integrity of the entire work will be appropriately addressed. This review discusses the implications of this paradigm shift on authorship requirements with the aim of increasing awareness on good scientific and editorial practices.  相似文献

Lay persons who are trained to conduct research in their own communities form an essential part of many research projects. However, the effects of conducting research in their own communities have not been adequately explored. This paper examines the experiences, perceptions, and challenges faced by a group of community researchers during their involvement in a research project that examined if, and how, the relationships between mothers and their adolescent daughters could be harnessed to develop a daughter-initiated cervical cancer intervention. Seven community researchers interviewed 157 mother-daughter pairs in Cape Town, South Africa. We examine the use of journaling as a tool to document the experiences of community researchers, and we consider how journaling may help the community-based researcher grapple with the research process, and, more broadly, what such journal content illustrates with respect to the nature and challenges of community-engaged health research. An analysis of the content of the journals provides a strong indication of how personal and intimate the research process can be for community researchers by virtue of the background that they bring into the process as well as the additional weight of the research process itself. The complexities of navigating dual and somewhat oppositional roles - the role of impartial scientist or researcher and the role of invested community person - has been both underestimated and insufficiently researched.  相似文献
