Procrastinators lack a broad action perspective

In the first study, the hypothesis was tested that in general optimistic procrastinators have chronically high action identities (i.e., a broad perspective on their actions), whereas pessimistic procrastinators have chronically low action identities to describe their behaviour. However, the data of the first study suggested that all procrastinators lack high action identities. The second study was set up to confront our original hypothesis with the alternative one that was based on the findings of the first study. Procrastinating students (classified based on questionnaire data), irrespective of type, were found to lack high action identities to describe their study activities, to have more specific intentions regarding studying, to postpone more of their intentions, and study less in general than did nonprocrastinators. Some recommendations are made to provide students with higher action identities. Copyright © 2000 John Wiley & Sons, Ltd.     

Conceptualizing parental autonomy support: adolescent perceptions of promotion of independence versus promotion of volitional functioning

In current research on parenting, 2 ways of conceptualizing perceived parental autonomy support can be distinguished. Parental autonomy support can be defined in terms of promotion of independence (PI) or in terms of promotion of volitional functioning (PVF). This study aimed to establish the empirical distinctiveness of both conceptualizations and to examine their relative contribution to the prediction of adolescents' adjustment. The authors conducted 3 studies, 2 which sampled late adolescents (N=396, mean age=18.70 years, 79% female; and N=495, mean age=19.30 years, 74% female, respectively) and 1 which sampled middle adolescents (N=153, mean age=15.12 years, 70% female). Factor analyses pointed to the distinction between perceived PVF and PI. Structural equation modeling (SEM) indicated that whereas perceived PVF uniquely predicted adjustment (ps<.01), perceived PI did not (ps>.05). SEM also demonstrated that adolescents' self-determined functioning significantly mediates the relationship between perceived parental PVF and adjustment (ps<.001). Results are discussed in terms of the type of autonomy that parents might want to facilitate among their adolescents to foster well-being.     

Parenting styles and psychological needs influences on adolescent life goals and aspirations in a South African setting

The present study examined the role of parenting styles and basic psychological needs in the adoption of goals and aspirations of learners, as well as for their psychological wellbeing (positive versus negative affect) in a South African sample of learners. A cross-sectional design was used to conduct this study with a sample of 853 learners at public schools in the Western Cape of South Africa (females?=?57%, mean age 16.96 years, SD?=?1.12). Data were collected using the Parenting Style and Dimensions Questionnaire (PSDQ), Psychological Needs Scale, Aspiration Index and the Positive And Negative Affect Schedule (PANAS). The results suggest that authoritative and authoritarian parenting styles influence the adoption of life goals and psychological wellbeing of adolescents with fathers' negative parenting possibly reducing adolescent wellbeing. Extrinsic life goals was a significant predictor of positive affect, while need frustration was a significant predictor of negative affect. These findings suggest parenting styles and basic psychological needs influence life aspirations and psychological wellbeing of learners in a developing country context.     

At the borders of medical reasoning: aetiological and ontological challenges of medically unexplained symptoms

Medically unexplained symptoms (MUS) remain recalcitrant to the medical profession, proving less suitable for homogenic treatment with respect to their aetiology, taxonomy and diagnosis. While the majority of existing medical research methods are designed for large scale population data and sufficiently homogenous groups, MUS are characterised by their heterogenic and complex nature. As a result, MUS seem to resist medical scrutiny in a way that other conditions do not. This paper approaches the problem of MUS from a philosophical point of view. The aim is to first consider the epistemological problem of MUS in a wider ontological and phenomenological context, particularly in relation to causation. Second, the paper links current medical practice to certain ontological assumptions. Finally, the outlines of an alternative ontology of causation are offered which place characteristic features of MUS, such as genuine complexity, context-sensitivity, holism and medical uniqueness at the centre of any causal set-up, and not only for MUS. This alternative ontology provides a framework in which to better understand complex medical conditions in relation to both their nature and their associated research activity.     

Which influence tactics lead to sales performance? It is a matter of style

The application of influence is a key behaviour set at the heart of the sales role. But we know little about how or whether influence tactics affect salespeople's actual job performance. We extend existing research on salespeople's use of influence by: (1) showing that influence tactics can be used to predict objective sales performance (and delineating which tactics are most predictive); (2) demonstrating that the effect of tactics on performance varies across salespeople, and these patterns of influence effectiveness allow us to identify different influence ‘styles’ and (3) revealing that the influence styles our data uncover are not consistent with existing theoretical classifications of influence tactics. The article concludes with a discussion of theoretical and managerial implications, and directions for future work.     

High Speed: Amphetamine Use in the Context of Conventional Culture

While the use of cannabis is often anchored in subversive values, and the use of heroin is situated at the social margins, the use of amphetamines appears to be associated with more conventional values. Interviews with 55 Norwegian amphetamine and/or methamphetamine users reveal that the substance is used for three main reasons. First, amphetamines are used by binge drinkers to “keep the party going.” Second, amphetamines are used by segments of the marginalized working class to enable them to work longer hours. Third, amphetamines are used medically by some to treat self-diagnosed symptoms of illnesses such as attention deficit hyperactivity disorder (ADHD).
