ABSTRACTThe precarity of young people’s transitions to work has been a longstanding focus in youth studies. As Furlong and others have demonstrated, processes of social, political and economic restructuring have led to a pronounced instability for young people entering the labour market. While the notion of labour market precarity has gained attention, the ‘contamination’ of precarity into other spheres of life such as leisure has been less developed. This article seeks to extend these debates through interrogation of the concept of ‘leisure precarity’. Drawing on a qualitative study of youth leisure in Glasgow, it argues that temporal anxieties have reframed young people’s experiences and understandings of leisure such that young people have come to fear ‘empty’ or unproductive time. The pressures of juggling work and study, or looking for work, meant that most participants in our research had limited time free for leisure, and temporal rhythms became fragmented between past, present and future. The paper argues that these multiple and contradictory leisure dispositions reveal new forms of individualisation and uncertainty, as well as traditional patterns of inequality, thereby bringing youth transitions into dialogue with the study of precarity in the twenty-first century. 相似文献

ABSTRACTThis article has two objectives. The first and narrower is to formalize the p-value function, which records all possible p-values, each corresponding to a value for whatever the scalar parameter of interest is for the problem at hand, and to show how this p-value function directly provides full inference information for any corresponding user or scientist. The p-value function provides familiar inference objects: significance levels, confidence intervals, critical values for fixed-level tests, and the power function at all values of the parameter of interest. It thus gives an immediate accurate and visual summary of inference information for the parameter of interest. We show that the p-value function of the key scalar interest parameter records the statistical position of the observed data relative to that parameter, and we then describe an accurate approximation to that p-value function which is readily constructed. 相似文献

It is indicated to what extent the conditional normality of the distribution of one comnonent of a bivariate random vector given the value of the other component together with a restricted type of conditional normality or the marginal normality for the other component is equivalent to the bivariate normality of this random vector. 相似文献

Unbiased estimation methods that are in some way local on the parameter space have been initiated by Barankin (1948) and Fraser (1964). The later methods involving local unbiasedness are extended to higher (derivative or difference) order at a parameter value (θ) and provide a basis for a computer algebra implementation concerning the improvement of unbiased estimates. 相似文献

The current study examined the associations between multiple aspects of the friend relationship (connection, companionship, psychological control) and global prosocial behavior toward friends. Participants included 467 early adolescents (M age of child = 13.32, SD = 1.05, 49% female, 69% European American), and data were collected at two time points, roughly 1 year apart. Structural equation modeling suggested that friend psychological control was negatively associated with prosocial behavior toward friends, while friend connection was positively associated (via adolescent sympathy). Discussion focuses on the friend relationship as an important influence on adolescent sympathy and prosocial behavior toward friends. 相似文献

A moderate common factors approach is proposed as a synthesis or middle path to integrate common and specific factors in evidence-based approaches to high-risk youth and families. The debate in family therapy between common and specific factors camps is reviewed and followed by suggestions from the literature for synthesis and creative flexibility in manual development. A preliminary integrative model termed Integrative Family and Systems Treatment is offered as one option in developing and testing a moderate common factors approach. Such a model might then be studied in eventual clinical trials with other well-developed evidence-based protocols to further address the common versus specific factor debate. Implications for further research and practice are offered. 相似文献

Changes in gay and bisexual men’s connectedness to the gay community are related to the declining public visibility of HIV/AIDS and greater acceptance for homosexuality and bisexuality in mainstream society. Little work, however, has focused on perceived acceptance for subgroups within the gay community or broader society. Using interviews (n = 20) and a survey (n = 202) of gay and bisexual men in a mid-sized Canadian city, we find perceived hierarchies of acceptance for the various subgroups as well as an age effect wherein middle-aged men perceive the least acceptance for all groups. These differences are linked with the uneven impact of social, political, and institutional changes relevant to gay and bisexual men in Canada. 相似文献

This paper presents an overview of some recent results concerning statistical models and inference. specifically: grounds for statistical models. types of models that simplify by standard probability analysis, the use of categorical information in the reduction of the model with data, and the role of additives in the inference process. The relevant technical material has been developed elsewhere. 相似文献
