Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Do health consultations for people with learning disabilities meet expectations? A narrative literature review
Get PDFThis is the peer reviewed version of the following article: Chapman, H. M., Lovell, A., & Bramwell, R. (2018). Do health consultations for people with learning disabilities meet expectations? A narrative literature review. British Journal of Learning Disabilities, 46(2), 118-135. https://doi.org/10.1111/bld.12222, which has been published in final form at https://onlinelibrary.wiley.com/doi/10.1111/bld.12222. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-ArchivingAim: To explore the benefits and disadvantages of annual health checks for people with learning disabilities, including: • What are the rationales and outcome measures for health checks? • How well do health checks meet the needs of people with learning disabilities? • What areas does research in this topic need to focus on in the future? Background Health consultations are an interpersonal activity that influence health outcomes and attitudes towards self and health professionals for people with learning disabilities. Annual health checks have been introduced to improve health inequalities for people with learning disabilities Method A narrative literature review of health care for people with learning disabilities was undertaken to evaluate health care for this population, and specifically the outcomes from annual health checks. Findings: While annual health checks have made some improvements in terms of health outcomes, attendance for appointments is still low, provision is variable and experiences of health checks for people with learning disabilities are under-researched. Conclusions: Service-user-led research into their health experiences is needed. Research into the attitudes and experiences of health professionals in relation to people with learning disabilities is needed. Health care inequalities are only being partially addressed – improvement is needed in terms of service user experience and engagement
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

The definitive version was published in Geobiology 15 (2017): 211–224, doi:10.1111/gbi.12222.Records of the Ediacaran carbon cycle (635 to 541 million years ago) include the
Shuram excursion (SE), the largest negative carbonate-carbon isotope excursion in
Earth history (down to -12 ‰). The nature of this excursion remains enigmatic given the
difficulties of interpreting a perceived extreme global decrease in the δ13C of seawater
dissolved inorganic carbon (DIC). Here, we present carbonate and organic carbon
isotope (δ13Ccarb and δ13Corg) records from the Ediacaran Doushantuo Formation along
a proximal-to-distal transect across the Yangtze Platform of South China as a test of the
spatial variation of the SE. Contrary to expectations, our results show that the
magnitude and morphology of this excursion and its relationship with coexisting δ13Corg
are highly heterogeneous across the platform. Integrated geochemical, mineralogical,
petrographic, and stratigraphic evidence indicates that the SE is a primary marine
signature. Data compilations demonstrate that the SE was also accompanied globally by
parallel negative shifts of δ34S of carbonate-associated sulfate (CAS) and increased
87Sr/86Sr ratio and coastal CAS concentration, suggesting elevated continental
weathering and coastal marine sulfate concentration during the SE. In light of these
observations, we propose a heterogeneous oxidation model to explain the high spatial
heterogeneity of the SE and coexisting δ13Corg records of the Doushantuo, with likely
relevance to the SE in other regions. In this model, we infer continued marine redox
stratification through the SE but with increased availability of oxidants (e.g., O2 and
sulfate) limited to marginal near-surface marine environments. Oxidation of limited
spatiotemporal extent provides a mechanism to drive heterogeneous oxidation of
subsurface reduced carbon mostly in shelf areas. Regardless of the mechanism driving
the SE, future models must consider the evidence for spatial heterogeneity in δ13C
presented in this study.We thank the National Key Basic Research Program of China (Grant
