Drawing on employment records, qualitative interviews, and a survey, we explore the experiences of apprentices in the highway trades in Oregon. We demonstrate that female and racial/ethnic minority apprentices have lower rates of recruitment and retention and disproportionately face challenges with interpersonal interactions, hiring practices, and supervisory practices. Yet, we find a pervasive narrative that attributes apprentices' success to “hard work,” which contributes to the legitimacy of these inequalities. Consistent with the conceptualization of work organizations as inequality regimes, we argue that the apprenticeship system has policies, practices, and ideologies that are on the surface gender and race/ethnicity neutral, yet lead to the perpetuation of inequalities. 相似文献

This paper presents findings from a study exploring the views of people with personality disorder diagnoses and various professionals working with them. After outlining the policy context and the study's conceptual framework, the aims and methods are described. Interviews were conducted with 12 service providers and 10 users. The main findings are then discussed, including user and provider perspectives on the meaning of 'personality disorder' and the strategies and support people use to address their difficulties. Finally, the theoretical implications of the findings are discussed. 相似文献

The 'Tasmania Together' social futures plan for Tasmania is critically examined. Authored by a Tasmanian Government appointed Community Leaders Group, on behalf of the people of Tasmania, the plan is supposed to deliver a better Tasmanian society by 2020, based upon community consultation. Rather than a step-forward in democracy, the process serves to remove the democratic rights of people, especially those who are disadvantaged. A critique from a disability perspective is offered, which suggests that this social plan constitutes a form of institutionalised disablism. 相似文献

The completely random character of radioactive disintegration provides the basis of a strong justification for a Poisson linear model for single-photon emission computed tomography data, which can be used to produce reconstructions of isotope densities, whether by maximum likelihood or Bayesian methods. However, such a model requires the construction of a matrix of weights, which represent the mean rates of arrival at each detector of photons originating from each point within the body space. Two methods of constructing these weights are discussed, and reconstructions resulting from phantom and real data are presented. 相似文献

The ability to infer parameters of gene regulatory networks is emerging as a key problem in systems biology. The biochemical
data are intrinsically stochastic and tend to be observed by means of discrete-time sampling systems, which are often limited
in their completeness. In this paper we explore how to make Bayesian inference for the kinetic rate constants of regulatory
networks, using the stochastic kinetic Lotka-Volterra system as a model. This simple model describes behaviour typical of
many biochemical networks which exhibit auto-regulatory behaviour. Various MCMC algorithms are described and their performance
evaluated in several data-poor scenarios. An algorithm based on an approximating process is shown to be particularly efficient. 相似文献

This paper investigates whether the perceived visioning behaviours of leaders influence the burnout process experienced by their followers. A structural equation model was used to examine these relationships using a sample of 480 senior managers from an Australian law-enforcement organization. Differences in the relationships between the two factors of visioning behaviour and aspects of burnout were identified. Inspirational motivation (concept-based) reduced the central factor of burnout, namely emotional exhaustion (psychological strain). Inspirational motivation (image-based) had a positive effect on personal accomplishment (self) and reduced depersonalization. The paper discusses the implications for leaders and followers and identifies directions for future research. 相似文献

This paper reports the findings from a recent study of nurse leavers at eight large hospitals in the National Health Service (NHS) of England and Wales. The study develops and extends an influential theory of employee turnover by describing how for some leavers a single, jarring event or shock triggers the decision to quit. By elaborating on the nature of shocks for this sample of 352 nurse leavers, the paper allows for improved understanding of nursing turnover and thus offers an example of relevant management research. The analysis of shock illustrates how conventional research methodologies can lead to a distorted picture of turnover. This has wider implications, both for any organization wishing to manage turnover effectively and for future research. The paper adds to the limited body of empirical analysis on actual leavers, thereby contributing to an ongoing methodological debate concerning the use of proxy variables. By highlighting flaws in the dominant methodology used to study turnover, the paper offers an example of management research that is also rigorous, and thus ‘pragmatic’. 相似文献

This paper concerns the geometric treatment of graphical models using Bayes linear methods. We introduce Bayes linear separation as a second order generalised conditional independence relation, and Bayes linear graphical models are constructed using this property. A system of interpretive and diagnostic shadings are given, which summarise the analysis over the associated moral graph. Principles of local computation are outlined for the graphical models, and an algorithm for implementing such computation over the junction tree is described. The approach is illustrated with two examples. The first concerns sales forecasting using a multivariate dynamic linear model. The second concerns inference for the error variance matrices of the model for sales, and illustrates the generality of our geometric approach by treating the matrices directly as random objects. The examples are implemented using a freely available set of object-oriented programming tools for Bayes linear local computation and graphical diagnostic display. 相似文献

Research has documented important connections between ethnic identity and academic success. In the multiethnic context of the US, ethnic self-identification is a dynamic process that develops through social interaction within institutions. Understanding the emergence of a Latino self-identity within schools can provide insight into the meanings adolescents confer to a “Latino” identity and the relationship between a Latino self-identity and academic success. This study uses data from the National Longitudinal Study of Adolescent Health to examine (1) the association between a Latino self-identification in-school but not at home and academic well-being, (2) the association between a Latino self-identification in-school but not at home and school processes, and (3) whether school processes help to mediate the relationship between Latino self-identification in-school but not at home and academic well-being. Results suggest that while adolescents who identify as Latino at school but not at home come from families and neighborhoods with higher levels of economic and human capital, by the end of high school they have accumulated less educational capital then either consistently identifying Latinos or non-Latino whites. Much of this association can be explained by prior academic experiences, yet other factors associated with resistance to institutional norms and attending low performing schools may also be important. Results suggest that non-minority, underachieving adolescents may choose to self-identify as Latino in schools as a way to save face and avert identity crises and that perhaps youth in schools have come to associate a Latino identity with poor school performance. 相似文献
