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

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

The proper treatment of egophoricity in Kathmandu Newari

We develop a theory of so-called 'conjunct-disjunct marking', also known as 'egophoricity', in Kathmandu Newari. The signature pattern of egophoricity looks a bit like person agreement: In declaratives, there is a special marker that goes on first person verbs, but not second or third person (e.g. 'I drank-EGO too much'). But in interrogatives, the same marker goes on second person (e.g. 'Did you-EGO drink too much?'). This is called interrogative flip. Egophoric marking also interacts interestingly with the presence of evidential markers, and comes with an implication of knowing self-reference (emphasized in Newari by a restriction to volitional action). Our paper discusses two previous approaches, which we label indexical and evidential, and motivate our account, which we label egophoric. Along the way, we develop a theory of how de se attitudes are communicated.http://eecoppock.info/egophoricity-oup.pdfAccepted manuscrip
