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

The Effects of Voluntary and Presumptive Sentencing Guidelines
No full textThis Article empirically illustrates that the introduction of voluntary and presumptive sentencing guidelines at the state-level can contribute to statistically significant reductions in sentence length, inter-judge disparities, and racial disparities.
For much of American history, judges had largely unguided discretion to select criminal sentences within statutorily authorized ranges. But in the mid-to-late twentieth century, states and the federal government began experimenting with sentencing guidelines designed to reign in judicial discretion to ensure that similarly situated offenders received comparable sentences. Some states have made their guidelines voluntary, while others have made their guidelines presumptive or mandatory, meaning that judges must generally adhere to them unless they can justify a departure.
In order to explore the effects of both voluntary and presumptive sentencing guidelines on judicial behavior, this Article relies on a comprehensive dataset of 221,934 criminal sentences handed down by 355 different judges in Alabama between 2002 and 2015. This dataset provides a unique opportunity to address this empirical question, in part because of Alabama’s legislative history. Between 2002 and 2006, Alabama had no sentencing guidelines. In 2006, the state introduced voluntary sentencing guidelines. Then in 2013, the state made these sentencing guidelines presumptive for some non-violent offenses.
Using a difference-in-difference framework, we find that the introduction of voluntary sentencing guidelines in Alabama coincided with a decrease in average sentence length of around seven months. When the same guidelines became presumptive, the average sentence length dropped by almost two years. Further, using a triple difference framework, we show that the adoption of these sentencing guidelines coincided with around eight to twelve-month reductions in race-based sentencing disparities and substantial reductions in inter-judge sentencing disparities across all classes of offenders. Combined, this data suggests that voluntary and presumptive sentencing guidelines can help states combat inequality in their criminal justice systems while controlling the sizes of their prison populations

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
