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
Deliberate self-harm in urban Uganda – a case-control study
Get PDFBackground: Deliberate self-harm (DSH) is both a personal problem and a public health problem not only in the West but also in sub-Saharan Africa including Uganda. Generally however, there is an absence of suicide interventions on the continent and linked to this problem an absence of recent studies on suicidal behaviour from Africa. To partly address these shortcomings, this present project examined the demographic, social and psychological characteristics of deliberate self-harm in the urban environment of Uganda.
Methods of the study: One hundred cases of deliberate self-harm attending three general hospitals in the Ugandan capital of Kampala were compared with 300 non-DSH in-patient controls from the participating hospitals. Both the cases and controls were interviewed using a Luganda translated version of the modified European Parasuicide Interview Schedule I (EPSIS I; Kerkhof et al. 1989). Two study samples were constituted where sample 1 were the cases and sample 2 the controls. For purposes of DSH repetition part of the study, sample 1 was split into the ‘suicide repeaters’ and the ‘non-repeaters’. Data on; socio-demographics, methods of DSH, precipitating factors of present act of DSH, life events, psychological factors and DSH repetition was collected.
Analysis: The statistical package SPSS 8.0 was used both at data entry and analysis. Analysis involved the generation of frequencies, means and mean rank scores and cross-tabulations using Pearson’s Chi-square test, Fischer’s Exact test and the independent t-test. Multivariate analysis using logistical regression was used to determine the independent effect of various variables in suitably specified models. The level of significance was set at 0.05.
Results: Results revealed that DSH in urban Uganda in a hospital based population was predominantly a problem for male (63%), adolescents and young adults (50%). The predominant method of DSH used was by organophosphate poisoning (45%). The main psychiatric diagnoses associated with DSH in this population were; adjustment disorder (35%), acute stress reaction (18%) and depression (23%).
Disturbed interpersonal relationships (with a partner/lover, parent(s) or children) were a precipitant in 65% of the DSH cases. The number of negative life events in; Childhood (categories of parents, significant others, and personal), Later in life (category of partner), and Last year (category personal and the total number of life events) were significantly associated with DSH in this study. The psychological factors found to be associated with DSH were; global psychological distress, hopelessness and state anger but not depression, trait anger nor alcohol abuse. Suicidal intent was found to be independently correlated with both depression and hopelessness.
Twenty five percent of the DSH cases in this study were repeaters with the socio-demographic factors associated with repetition of DSH including; being single, having children and staying alone or with parents. Other factors found to be associated with DSH repetition were; the number of negative life events in childhood and in the last year, global psychological distress and trait anger but not depression, hopelessness nor state anger.
Conclusion: The picture of DSH in urban Uganda is similar to a great extent to that observed elsewhere on the African continent and in the West. There are however important differences particularly with the picture of DSH as seen in the West.PhD i psykologiPhD in Psycholog

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
