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
Treatment Efficacy for Antenatal Substance Use: A Meta-Analysis
Full text linkThis study was a meta-analysis of treatment outcome studies that have examined substance use treatment for pregnant women. To date, there have been no systematic reviews of this literature. Two independent coders collected the available studies and independently coded multiple variables, including statistical, methodological, client, and program factors. Quantitative outcomes were aggregated a) to determine whether substance use treatment programs for pregnant women were effective, and b) to examine additional variables, such as the type of intervention or treatment setting, that may have moderated the overall treatment effect. Twentysix studies met inclusion criteria. The overall treatment effect when aggregating across outcome variables was in the small to moderate range; the standard difference of means (SDM) was .3 (p<.001). Treatment seemed to have the greatest impact (SDM=.7, p<.0001) on maternal outcome variables, such as employment status, comorbid mental health disorders, parenting skills, prenatal visit compliance, and medical and health status. When assessing the overall treatment effect as determined by treatment/drug use outcomes, the SDM was .3 (p<.0001). For birth outcomes, the overall SDM was .2 (p<.001). Both the type of intervention treatment and the treatment setting significantly moderated the overall treatment effect. Substance use programs targeting pregnant women with substance use disorders appear to be beneficial, especially when a behavioral-contingency component or methadone maintenance component is added to the treatment protocol.M.S., Psychology -- Drexel University, 201
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
A survey of clinical neuropsychologists with experience in forensic contexts: prevalence, training, and jurisdictional differences in civil and criminal cases
No full textDespite the rapid growth of the subspecialty known as forensic neuropsychology, little is known about the prevalence of neuropsychologists acting as experts in civil and criminal forensic contexts, the training undertaken by these neuropsychologists, or differences in their practices across civil and criminal cases, legal questions, or jurisdictions. Neuropsychologists with experience in the forensic context were surveyed to address these gaps. The majority of participants reported conducting evaluations in both civil and criminal forensic contexts across a variety of legal issues, while others restricted their practices to civil cases alone. Participants appeared to have specialized early in neuropsychology through formal graduate and continued post-graduate training, while their training in forensic concepts appears to have occurred primarily through postgraduate continuing education and supervision. No jurisdictional differences were found between neuropsychologists conducting evaluations in civil cases, though participants were more likely to practice in criminal cases in Frye states. Challenges to the admissibility appeared infrequent, and were more likely to be partial challenges instead of challenging participants’ qualifications as experts overall. Continued investigation of neuropsychologists practicing in civil and criminal contexts will remain important as the subspecialty of forensic neuropsychology continues to develop. This is especially relevant given the growing role of neuropsychology in better informing decision-making in the United States legal system.M.S., Psychology -- Drexel University, 201
A survey of forensic mental health professionals with experience conducting criminal responsibility evaluations
Full text linkForensic mental health professionals have conducted criminal responsibility (CR) evaluations for decades; however, relatively little is known about the specific methodologies employed when conducting such evaluations. The current study surveyed 135 forensic psychologists and psychiatrists, examining components of CR evaluations, the use of psychological tests, time delay between offense date and evaluation date, and relationship between evaluator experience and opinions about CR evaluations. Results suggest very few differences between professional disciplines relating to reliance upon collateral records, number of collateral interviews conducted, and use of psychological assessment measures. Psychiatrists reported typically including a recognized psychiatric diagnosis in reports significantly more than psychologists. Respondents from both disciplines reported lengthy time delays between offense date and evaluation date, with time delays from respondents’ most recent evaluations averaging almost 10 months. Experience conducting CR evaluations was positively correlated with higher levels of confidence in ability to conduct accurate CR evaluations and greater knowledge of legal standards. The vast majority of respondents reporting that they felt they could detect when an examinee was malingering. Implications and future directions are discussed.
