UNDERSTANDING THE CONTEXT OF RISK PRACTICES AMONG INJECTING DRUG USERS: IMPLICATIONS FOR HEPATITIS C PREVENTION

‘Risk’ is central to recent sociological studies of health and related behaviour, particularly in discourses about HIV/AIDS and hepatitis C (HCV). While epidemiological survey predominates over qualitative investigation in HCV risk reduction, it is necessary to move beyond individual‐level characteristics to gain a fuller understanding of the social context of risk. This paper investigates the context of HCV‐related risk behaviour among injecting drug users (IDUs) and discusses the behavioural and social determinants of risk practices. Data from 336 IDUs completing a self‐administered questionnaire were analysed. The data show that needle‐sharing practices are often integral to long‐standing relationships, particularly sexual ones. The level of drug dependency, trust relationships between partners and misconceptions about HCV transmission have been demonstrated to be associated with risk behaviour. Logistic factors, such as poor access to injecting equipment, limited hours of operation, and fear of police were given as barriers to safer injecting. Given the progression of the HCV epidemic, prevention campaigns should aim at risk reduction rather than risk elimination.     

Strategic decision‐making: Process perspectives

This paper reviews the strategic decision‐making process literature with respect to the synoptic formalism/political incrementalism debate. Procedural rationality is chosen as a representative of the synoptic formalism perspective; and both intuitive synthesis and political behaviour are employed as representatives of the political‐incrementalism perspective. In this paper, the author discusses the theoretical underpinnings of these three process dimensions, as well as the key research efforts gathered together under each perspective. In conducting this review, a number of areas have been identified which could profitably be examined further, and a number of implications for managers will be highlighted and discussed.     

On the optimality of a class of minimal covering designs

It is shown that the minimal covering designs for v=6t+5 treatments in blocks of size 3 are optimal w.r.t. a large class of optimality criteria. This class of optimality criteria includes the well-known criteria of A-, D- and E-optimality. It is conjectured that these designs are also optimal w.r.t. other criteria suggested by Takeuchi (1961).     

A Simpler Approximation for Areas under the Standard Normal Curve

A simple approximation for areas under the standard normal curve is presented that is suitable for use when tables and/or calculators are not available or not permitted.     

It’s Complicated: Sociocultural factors and the Disclosure Decision of Transgender Individuals in Pakistan

The literature on the disclosure decision of transsexual individuals is sparse, and that which does exist either uses empirical quantitative methods or aggregates transsexuals with other non-heterosexual individuals. The current study focuses this underresearched group and examines the disclosure decision of transsexual people in Pakistan, a developing Muslim country with a unique amalgam of social, cultural, and religious ground realities. Drawing on thematic analysis technique using in-depth interviews with 16 transsexuals, we show how sociocultural factors that are inherently embedded in the environment influence the disclosure decision in work and non-work settings. In particular, our respondents illustrate that their disclosure decision, which ranges from total disclosure on one end to nondisclosure on the other end, is influenced by the complexities of family honor, tightly integrated family network, social obligation to get married, and prevalent religious beliefs in the society. This study advances understanding of identity and disclosure decision of transsexual individuals by explicating the ways in which sociocultural factors are intricate part of their decision of coming out.     

Consumer Culture Theory,Nonverbal Communication,and Contemporary Politics: Considering Context and Embracing Complexity

This commentary addresses Olivola and Todorov’s “Elected in 100 ms: Appearance-Based Trait Inferences and Voting” and considers its valuable contribution to the field of nonverbal communication. This work suggests that contemporary politics and voting behavior are so complex that they can be better understood outside of laboratory settings where the vital elements on culture and context come into play. By using consumer culture theory and other cultural theories of branding, this commentary evaluates elements of Barack Obama’s presidential run, and considers why his campaign resonated so well with voters in contemporary United States culture.     

Can balance exercise programmes improve balance and related physical performance measures in people with dementia? A systematic review

This review presents the physical performance outcomes of randomised trials investigating exercise programmes that included balance exercise for older people with dementia. A systematic literature search through five computerised bibliographic databases until February 2009 was carried out. Of 1,038 potentially relevant published articles, only seven met the inclusion criteria and were extracted. Findings from the review for a total of 632 participants showed that almost all of the included studies addressed exercise or physical activities as the main intervention; however, only two of the studies focused on balance exercise. The effect size values varied from no effect (0.00) to a large effect (3.29) of the interventions for a range of physical performance outcome measures. Findings also suggest that it is feasible to conduct exercise programmes with older people with dementia. However, further studies with more specific exercise designed to improve balance performance in order to prevent falls are required for older people with dementia.
