The illegal drug use behaviour and social circumstances of older adult class A drug users in Britain
Full text linkSubstance use problems are seen as the domain of younger age groups. However, recent trends in drug use and the demand for drug treatment show an increasing prevalence among older adults. Over the next twenty years it is anticipated that the number of older substance users will increase. It is therefore becoming more important to understand the compound challenges faced by older adults who use class A drugs.
The research questions for this study are: What are the illegal drug use behaviours and social circumstances of adult class A drug users over 50 in England? and How and why do they use class A drugs?
To answer these questions a constructivist grounded theory methodology was adopted. Semi-structured, face-to-face interviews were conducted with 30 (24 men and six women) participants, over 50 years old, living in England. All participants had used a class A drug in the last month.
The results showed a heterogeneity of social circumstances among the sample. For the majority of the participants their drug use was highly dynamic - frequently managed in line with their circumstances. These participants also adapted their drug use in line with their awareness of their changing physical vulnerability. For others however, their drug use was fixed and linear. All participants’ drug use is described by the major category ‘managing lifestyle’. Participants were using drugs to change the way they felt - described by the major category ‘altering feelings’. The data also suggested an apparent interaction between how and why these participants were using drugs. A model of drug use in older adults was developed from the fourteen major categories - underpinned by the core category ‘achieving balance’. It describes a process of ongoing balancing, influenced and informed by the participants’ experiences of the past and expectations of the future
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
Investigating the role of festivalscape in culinary tourism: The case of food and wine events
No full textThis paper analyses the importance of festivalscapes in determining emotions, satisfaction and future
behavior of participants at food and wine events. The study applies a structural equation model (SEM)
with latent variables to survey responses of visitors to the “Friuli DOC” Italian festival. The main results
are that festivalscape and emotions have significant direct effects on satisfaction, which in turn has
a significant effect on behavioral intention. The effects of the festivalscape on visitors’ future behavior are
only indirect and mediated by satisfaction. Thus, in order to enhance their visitors’ behavioral intentions,
festival organizers should monitor emotions and satisfaction deriving from the subjective perception of
exogenous characteristics as food and wine quality, comfort and entertainment
The determinants of food festival attendees' intention to revisit
No full textIn this paper we disentangle the roles of emotional and cognitive responses in determining behavioral intentions in food and wine events. We estimate a structural equation model on a sample of 380 people attending in 2007 the food and wine festival “Friuli Doc”, allowing for direct and indirect effects of different factors on the future behavior of participants. The only significant direct effect on Behavior comes from the “emotional” factor, while “cognitive” factors have only an indirect effect. Service quality, which is the only exogenous factor directly controlled by event organizers, has a direct effect on experience quality and on perceived service value, but only indirect effects on both satisfaction and behavior. Thus, an increased service quality may have an effect on future behavior only if it changes the perception of participants about the quality of their experience or the overall value of the event
