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
Police Recruitment Videos and their Relevance for Attracting Officers
No full textThis brief is based on the following published work:Simpson, R. (2023). Police recruitment videos and their relevance for attracting officers. Policing: A Journal of Policy and Practice, 17, 1-13. https://doi.org/10.1093/police/paac057
Police recruitment videos are a widely used and highly salient form of police marketing. These videos can attract prospective applicants, communicate information about a policing career with a given agency, and help prospective applicants to assess their potential fit with that agency.
Police agencies tend to highlight the more thrilling and high-risk elements of policing in their recruitment videos rather than the more community-oriented and low-risk elements of policing.
The content of recruitment videos could impact who decides to pursue policing careers, the behaviour of officers once hired, as well as officer satisfaction and retention. Police leaders should pay careful attention to the content of their recruitment videos
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

Officer Appearance and Perceptions of Police: Beyond an Instrumental Function, Toward a Signaling Framework
Full text linkAs an institution, the police are particularly sensitive and vulnerable to public opinion. Building upon existing research, this dissertation contributes to the policing literature by employing an experimental methodology in order to explore the effects of aesthetic factors associated with the police on perceptions of the police. As part of the experimental design, participants from a large public university (N = 399; Chapters 1-3) and Amazon’s Mechanical Turk (N = 349; Chapter 4) were presented with images of several different police officers under the guise of a memory study, and asked to rate them along six important outcomes: aggressive versus not aggressive, approachable versus not approachable, friendly versus not friendly, respectful versus not respectful, accountable versus not accountable, and competent versus not competent. In each image, the appearance of the pictured officer was carefully manipulated in order to empirically test the effects of different elements of appearance on perceptions of officers. For example, when presented on foot, officers were equipped with different accoutrements, including vests, gloves, batons, sunglasses, and baseball hats (Chapter 1). When presented in a police vehicle, officers occupied different styles of vehicles, including marked and non-marked vehicles with different color schemes (Chapter 2). Across all of the different aesthetic capacities, officers exhibited either a neutral facial expression or a smile (Chapter 3). The results revealed that police appearance significantly impacted perceptions of officers along all of the dependent variables. The validation analyses also revealed that the effects of police appearance were consistent across both samples of participants (Chapter 4). I argue that different elements of police appearance signal different types of officer intent, influence perceived legitimacy, and shed insight into the philosophical orientations of police. I conclude the dissertation by discussing the results from the experiment in the context of theory and methodology as well as policy and practice
