Ketamine use: minimising problems and maximising pleasure
In January 2006 ketamine shifted from medical regulation through the Medicines Act to a Class C drug through an amendment to the Misuse of Drugs Act. In the debate surrounding this criminalisation, interest has grown in prevalence and patterns of ketamine consumption. Such information is scarce however, particularly given that ketamine has yet to be included in the British Crime Survey or most other surveys of youth and young adult drug use. Here Karenza Moore and Fiona Measham reveal the true extent of ketamine use, who is using it and how.</jats:p
A more fluid approach to drinking
Young adults are consuming less alcohol than previousgenerations. Dominic Conroy and Fiona Measham lookto understand changing ‘styles’. Might a consideration offluid/transient ‘drinking styles’, alongside traditional harm-focused approaches, be the key to understanding young adult drinking practices
“Doing Gender”—“Doing Drugs”: Conceptualizing the Gendering of Drugs Cultures
Women's illicit drug use has been increasing rapidly in the 1990s in the UK and elsewhere in the developed world. Lifetime prevalence rates show that gender is no longer a significant predictor of, or protector from, illicit drug use. The concentration on lifetime prevalence in the academic debate, however, has been to the detriment of the wider cultural context of drug-related attitudes and behavior in drug-using groups and wider society. This paper considers the socio-cultural context of gender and drug use, and reasserts the central importance of gender to our understanding of drugs cultures. Drug use is not just mediated by gender, but, far more significantly, drug use and the associated leisure, music and style cultures within which drug use is located are themselves ways of accomplishing a gendered identity. Building on Messerschmidt's concept of crime as structured action, the author suggests that gender does not just influence “doing drugs”–drug use itself can be seen as a way of “doing gender.” </jats:p
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
