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
Impact of joint forest management on forest resource base and livelihoods of communities in Amani nature reserve, Muheza district, Tanzania
No full textJoint Forest Management (JFM) is an institutional arrangement considered to be a proper
way forward for alleviating forest degradation. However, since the inception of JFM in
Amani Nature Reserve (ANR), its impacts to the forest resource base and livelihoods of
surrounding communities is not clearly known. Therefore the study assesses the impacts of
JFM on both forest resource base and livelihoods of the local communities around ANR.
Forest inventory was carried out by laying out 30 sample plots systematically. In the plots,
diameter at breast height and heights of all the trees were measured, recorded and tree
species were identified. Livelihood attributes were collected using a questionnaire,
checklist for key informants and a number of PRA techniques. To assess impact, both
inventory and livelihoods data were compared between 2001 and 2005. Microsoft Excel
Software was used to analyse quantitative data for various forest parameters. Data
collected during PRA were analyzed with the help of the local community. Content and
structural-functional analyses were applied to analyse socio-economic qualitative data.
Statistical Package for Social Sciences (SPSS) was used to analyse the socio economic
quantitative data. Logistic regression analysis model was developed to identify socio-
economic factors influencing participation of local communities surrounding ANR in JFM.
The study found that 3043 ± 360 (SE) stems per hectare were obtained in 2005 compared
to 1762 ± 225(SE)) of 2001 indicating significant increase (t = 3.09; p=0.004) though,
dominated by small diameter class of 2.5-10cm. The basal area and wood volume
decreased suggesting that there was tree cutting in ANR. Species diversity indices
increased from 3.271 to 3.379 between 2001 and 2005 indicating that the forest is still
facing human disturbance. Training sessions in JFM, tree planting, income shared from
forest under JFM and engagement of household in economic groups significantly (p<0.05)
increased the odds of participation of local communities by factors of 17.986, 45.894,
10.658 and 7.671 respectively. Household income and improved housing standards
significantly (p<0.05) influenced JFM performance. Poor monitoring capability as an
indicator of weaknesses in governance contributed to JFM to have negative impact on
basal area and wood. The study observed a positive impact on livelihoods. The study
among other things recommended improvement of in governance by ensuring transparency
and clear responsibilities of Village Natural Resources Committees
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
