Peer-group and price influence students drinking along with planned behaviour

This article is available open access through the publisher’s website at the link below. Copyright @ 2008 The Authors.Aims: To examine the theory of planned behaviour (TPB), as a framework for explaining binge drinking among young adults. Methods: One hundred and seventy-eight students in a cross-sectional design study completed self-report questionnaires examining attitudes to drinking, intention to drink and drinking behaviour in university. Binge drinking was defined for females (and males) as consuming ‘four (males—five) or more pints of beer/glasses of wine/measures of spirits’ in a single session. Results: Drinking alcohol was common; 39.6% of males and 35.9% of females reported binge drinking. The TPB explained 7% of the variance in intention to drink. Overall, 43% of the variance in intention, 83% of the variance in total weekly consumption and 44% of the variance in binge drinking was explained. The frequency of drinking and the drinking behaviour of friends significantly predicted intention to drink and binge drinking, respectively. Binge drinkers were influenced by peers and social-situational factors. Pressure to drink was greater for males; undergraduates were influenced by the size of the drinking group, ‘special offer’ prices, and the availability of alcohol. Conclusions: The TPB appeared to be a weak predictor of student drinking but this may be a result of how constructs were measured. With friends’ drinking behaviour emerging as a significant predictor of alcohol consumption, interventions seeking to reduce excessive drinking should target the role of peers and the university environment in which drinking occurs

Do sleep difficulties exacerbate deficits in sustained attention following traumatic brain injury?

Sustained attention has been shown to be vulnerable following traumatic brain injury (TBI). Sleep restriction and disturbances have been shown to negatively affect sustained attention. Sleep disorders are common but under-diagnosed after TBI. Thus, it seems possible that sleep disturbances may exacerbate neuropsychological deficits for a proportion of individuals who have sustained a TBI. The aim of this prospective study was to examine whether poor sleepers post-TBI had poorer sustained and general attentional functioning than good sleepers post-TBI. Retrospective subjective, prospective subjective, and objective measures were used to assess participants’ sleep. The results showed that the poor sleep group had significantly poorer sustained attention ability than the good sleep group. The differences on other measures of attention were not significant. This study supports the use of measures that capture specific components of attention rather than global measures of attention, and highlights the importance of assessing and treating sleep problems in brain injury rehabilitation

Price, Tobacco Control Policies and Smoking Among Young Adults

The effects of cigarette prices and tobacco control policies (including restrictions on smoking in public places and limits on the availability of tobacco products to youths) on cigarette smoking among youths and young adults are estimated using data from a nationally representative survey of students in U.S. colleges and universities. Smoking participation rates, the quantity of cigarettes smoked by smokers, and level of smoking equations are estimated using appropriate econometric methods. The estimates indicate that college students are quite sensitive to the price of cigarettes, with an average estimated price elasticity of smoking participation of -0.66 and an overall average estimated price elasticity of cigarette smoking of -1.43. In addition, relatively stringent restrictions on smoking in public places are found to reduce smoking participation rates among college students, while the quantity of cigarettes consumed by smokers is lowered by any restrictions on public smoking. Finally, limits on the availability of tobacco products to underage youths have no impact on college students, almost all of whom can legally purchase these products.

The Impact of Price, Availability, and Alcohol Control Policies on Binge Drinking in College

The effects of beer prices, alcohol availability, and policies related to driving under the influence of alcohol on drinking and binge drinking among youths and young adults are estimated using data from a nationally representative survey of students in U.S. colleges and universities. Drinking participation, participation in binge drinking and level of drinking equations are estimated using appropriate econometric methods. The estimates indicate that the drinking practices of college students are sensitive to the price of beer, with an average estimated price elasticity of drinking participation of -0.066 and an average estimated price elasticity of binge drinking of -0.145. However, when dividing the sample by gender, one finds that the effects of prices on drinking are limited to young women. In addition, a significant negative relationship is found for the strength of policies related to drinking and driving among youths and young adults and drinking by college students. However, the results indicate that many elements of campus life, (including participation in a fraternity or sorority, living on campus, and the ready availability of alcoholic beverages) are among the most important determinants of drinking and binge drinking among college students.

Scaffolding human-centred innovation through design artefacts

University of Technology Sydney. Faculty of Design, Architecture and Building.Human-centred innovation refers to innovation that is informed by customer insight. Contemporary organisations are increasingly turning to human-centred design approaches to inform both their human-centred innovation efforts and the associated shift to customer-centricity. Unlike invention and design, innovation requires implementation. It rests upon collective outcomes, generated from the combined activities of many stakeholders. Design artefacts have always been at the core of design practice, comprising both outcomes of as well as inputs into design processes. Within human-centred innovation contexts, design practice and the roles of design artefacts have distinct qualities. Design artefacts such as personas, prototypes, customer journey maps and videos communicating customer research provide designers and other staff with valuable mediatory and enabling tools within human-centred innovation processes. Organisational studies literature points to the valuable role artefacts play in communication, collaboration, social mediation, knowledge sharing and transformation; however there is a gap in the literature about the roles design artefacts play as inputs into the innovation process and as instruments to support innovation within organisations. Investigation into how design artefacts function to facilitate and motivate collective action, enable communication and support organisational transformation is the central motivation of this research. The research aims to examine the role of design artefacts as flexible tools that mediate the social, interlinked demands of human-centred innovation initiatives within organisations. Through a practice-led case study, using the conceptual framework of Activity Theory, we examine how some specific design artefacts supported an organisation in designing and delivering a specific human-centred innovation initiative. Data from participant observation and qualitative interviews, conducted with a sample of artefact recipients and design practitioners, informs examination of the various roles the case artefacts played within organisational activities. The study draws attention to the persuasive character of design artefacts, their role as social mediators, their ability to facilitate a customer-centric perspective for diverse organisational members and their potential to affect organisational change. The term ‘scaffold’ in the thesis title signifies structures that enable and support the work of others. The research illustrates how design artefacts can function to scaffold human-centred innovation within the organisation. It contributes to knowledge about human-centred innovation processes, the role of the designer, design artefacts and design practices within organisational contexts. This research is relevant for academics, design practitioners and management audiences alike

Are There Differential Effects of Price and Policy on College Students' Drinking Intensity?

This paper investigates whether college students' response to alcohol price and policies differ according to their drinking intensity. Individual level data on drinking behavior, price paid per drink, and college alcohol policies come from the student and administrator components of the 1997 and 1999 waves of the Harvard School of Public Health (HSPH) College Alcohol Study (CAS). Students drinking behavior is classified on the basis of the number of drinks they typically consume on a drinking occasion, and the number of times they have been drunk during the 30 days prior to survey. A generalized ordered logit model is used to determine whether key variables impact differentially the odds of drinking and the odds of heavy drinking. We find that students who faced a higher money price for alcohol are less likely to make the transition from abstainer to moderate drinker and moderate drinker to heavy drinker, and this effect is equal across thresholds. Campus bans on the use of alcohol are a greater deterrent to moving from abstainer to moderate drinker than moderate drinker to heavy drinker.
