Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
No full textWe 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
A case control study on personality traits and disorders among deliberate self-harm patients in Malaysian hospital
No full textObjective: This study was conducted to compare the personality traits in deliberate self-harm (DSH) patients with a control group matched for age, sex and race. Methods: A case-control study design was used in this study. A total of 50 consecutive admissions to Kuala Lumpur Hospital following episodes of deliberate self-harm were compared with equal number of controls from the admission for minor medical illness during the same period. They were assessed on socio-demographic profile, Axis I psychiatric diagnosis and personality traits. Results: The mean age for the cases and controls was 26 years old. Seventy-eight percent of them were females, mostly unmarried and majority had completed their secondary education. The respondents were Indians (52%), Malays (40%) and Chinese (8%). A high prevalence of major depression (22%) was found among the cases compared to none among the controls. Personality disorders were present in 68% of cases as compared to 38% among the controls, while sensitivity (p<0.0005), impulsivity (p<0.0005), and worthlessness (p<0.0005) were the commonly reported personality traits. Paranoid personality disorder (p<0.05) and borderline personality disorder (p<0.05) were significantly present in deliberate self-harm subjects compared to the control group. Conclusion: Psychiatric disorder, personality traits of sensitivity, impulsivity and worthlessness, and personality disorders of paranoid and borderline were common in DSH patients
The use of aripiprazole in early onset schizophrenia: safety and efficacy
No full textThe use of atypical antipsychotic agents in early onset schizophrenia is rising despite its limited data on efficacy, safety and tolerability. Early onset schizophrenia warrants effective pharmacological treatment that is safe and well tolerated by children and adolescent population. Existing atypical agents are not completely free of side effects. Aripiprazole has unique properties that differ from other atypical antipsychotics and fill up the missing gaps, as it is associated with minimal metabolic complications and extrapyramidal side effects that are more commonly seen in other atypical agents. It offers a better option for this population and may possibly be considered as first line treatment in future. This case report demonstrates the efficacy and safety of Aripiprazole in children and adolescent population
Life events and parasuicides in Hospital Kuala Lumpur, Malaysia
No full textObjective: The aim of this study is to compare the prevalence of life events among parasuicide patients with the prevalence of similar life events among age, sex and race matched patients with non-chronic medical illness. Methods: A hospital-based case-control study using convenience sampling method was conducted in Hospital Kuala Lumpur for a period of three and a half months. A total of 50 patients admitted consecutively after an episode of parasuicide and who fulfilled criteria for entry into the study agreed to participate. For each case one age-, sex- and race-matched control was selected from the list of patients who were admitted to the same hospital for non-chronic medical illness. Result: Statistical analysis showed that compared with medically ill patients, parasuicide patients had significantly higher prevalence of threatening life events six months (p<0.001) before their act and these life events were significantly concentrated in the last one month before the attempt (p=0.001). Among the seven categories of life events, cases had a significant excess of interpersonal problems (p<0.001) that included serious problems with a close friend, neighbour or relative, break-up of a steady relationship and separation due to marital difficulties. Conclusion: The results suggest that there is a high prevalence of life events among parasuicide patients when compared with medically ill patients especially during the month prior to their admission to the hospital. The data also indicate that there is a significant association between suicide attempts and interpersonal problems
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
