Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
Dissociative Phenomenology and General Health in Normal Population
Full text linkBackground: Dissociative symptoms are most commonly found in females and adolescents, and when dis- cussing their background, they can be from lower socio-economic backgrounds and rural areas. They are al- ways preceded by psychosocial stressors. Dissociative disorders previously known as “hysteria” have been described since antiquity and Hippocrates even hypothesised “wandering uterus” to be the cause for dissociation in females. With the advances in science, there has been shift from these religious and spiritual concepts to a scientific basis for dissociation. Aim: To assess the dissociative phenomenology in normal population and to assess the subjective health in normal population. Methods: A group of 100 (50 females & 50 males) were selected from the community using a snowball sam- pling technique. Tools: Socio-demographic data sheet, General Health Questionnaire-12 and Dissociative Experience Scale-II were used. Results: The study found that females differ from males in the reporting of subjective health rating (X2=5.76, p=0.01) and similar results shown in terms of dissociative phenomenology (X2=67.76, p=0.001). Discussion: It has been found that only 4% from the female group and 2% from the male group rated their health under the “normal” category. 52% of females and 64% of males were categorised under “mild ill health” and 24% to 26% were in “moderate ill health”, whereas 20% of female participants and 8% of male participants rated their health as “severely ill”. In another domain of the study, dissociative phenomenology, 32% of female participants reported severe dissociative symptoms and 38% of male participants also showed similar results. Conclusion: Dissociative disorder significantly affects the population but it is hard to diagnose due to factors such as; cultural factors, socio-economic factors etc. The study shows clearly that dissociative symptoms are found in the general population also
Role of Psychological Stressors in Dissociative Phenomenology
Full text linkBACKGROUND: Dissociative phenomena have been observed in clinical populations as an independent diagnostic category as well as in non-clinical populations. It has been observed that a person with dissociation has relatively more adverse stressful life experiences than healthy controls. Various studies indicated that stressful life events may have a causative role in dissociative disorders, however findings are inconsistent. OBJECTIVES: To study this link the present study has been planned with the aim to assess and compare stressful life events and dissociative experience in patients with dissociative disorders and healthy controls. METHODS: The study comprises 80 participants (40 dissociative patients and 40 healthy controls). In the sample total, 16 males and 64 females were enrolled. All participants assessed using the Presumptive Stressful Life Events Scale and Multidimensional Inventory of Dissociation. Healthy controls were screened by the General Health Questionnaire-12. RESULTS: In the results of both groups have significant difference in the experience of life time psychological stress [t=2.92; p=0.05] and the correlation positively related with dissociative experiences and stressful life events. The finding from regression analysis indicates that the degree of life time stress emerged as a predictor of dissociative psychopathology treatment outcome (R2= 0.23, Beta coefficient = 0.48, p = 0.000, 95% Cl = 0.21- 0.50). This indicates that patients who had significantly higher psychological stress predicted dissociative psychopathology. CONCLUSION: A significant difference was found between both groups in the Presumptive Stressful Life Events Scale, the clinical population has higher scores than the normal population and higher psychological stress predicted dissociative psychopathology
