We examine the relationships between electoral socio‐demographic characteristics and two‐party preferences in the six Australian federal elections held between 2001 and 2016. Socio‐demographic information is derived from the Australian Census which occurs every 5 years. Since a census is not directly available for each election, an imputation method is employed to estimate census data for the electorates at the time of each election. This accounts for both spatial and temporal changes in electoral characteristics between censuses. To capture any spatial heterogeneity, a spatial error model is estimated for each election, which incorporates a spatially structured random effect vector. Over time, the impact of most socio‐demographic characteristics that affect electoral two‐party preference do not vary, with age distribution, industry of work, incomes, household mobility and relationships having strong effects in each of the six elections. Education and unemployment are among those that have varying effects. All data featured in this study have been contributed to the eechidna R package (available on CRAN). 相似文献

Drawing upon the expectancy violation‐realignment theory of autonomy development, this qualitative study examined African American and Hmong adolescent autonomy‐seeking behaviors and parent–child communication about activities and relationships with peers. Twenty‐two African American and 11 Hmong adolescents in grades 6–12 and 14 African American and 8 Hmong primary caregivers were interviewed. Participants discussed their perspectives on adolescent information management regarding activities with friends. Four categories of information management strategies and four primary types of adolescent justifications were identified. Adolescents were pragmatic in their decisions about secretive behaviors but also considered the impact of their behaviors on their relationships with parents. Adolescent strategies were consistent across ethnic groups, whereas justifications for secretive behaviors were embedded within cultural and family experiences. 相似文献

Modeling Receptor-Mediated Processes with Dioxin: Implications for Pharmacokinetics and Risk Assessment 总被引:9,自引:0,他引:9

Dioxin (2,3,7,8-tetrachlorodibenzo- p -dioxin; TCDD), a widespread polychlorinated aromatic hydrocarbon, caused tumors in the liver and other sites when administered chronically to rats at doses as low as 0.01 μg/kg/day. It functions in combination with a cellular protein, the Ah receptor, to alter gene regulation, and this resulting modulation of gene expression is believed to be obligatory for both dioxin toxicity and carcinogenicity. The U.S. EPA is reevaluating its dioxin risk assessment and, as part of this process, will be developing risk assessment approaches for chemicals, such as dioxin, whose toxicity is receptor-mediated. This paper describes a receptor-mediated physiologically based pharmacokinetic (PB-PK) model for the tissue distribution and enzyme-inducing properties of dioxin and discusses the potential role of these models in a biologically motivated risk assessment. In this model, ternary interactions among the Ah receptor, dioxin, and DNA binding sites lead to enhanced production of specific hepatic proteins. The model was used to examine the tissue disposition of dioxin and the induction of both a dioxin-binding protein (presumably, cytochrome P4501A2), and cytochrome P4501A1. Tumor promotion correlated more closely with predicted induction of P4501A1 than with induction of hepatic binding proteins. Although increased induction of these proteins is not expected to be causally related to tumor formation, these physiological dosimetry and gene-induction response models will be important for biologically motivated dioxin risk assessments in determining both target tissue dose of dioxin and gene products and in examining the relationship between these gene products and the cellular events more directly involved in tumor promotion. 相似文献

While we commend Horwitz et al. (2003) for speaking to core issues in behavioral genetics, we disagree with many particulars of their article. We are skeptical of their claims regarding the particular contribution offered by both their methods and data. We believe also that the findings they present as challenging the equal environments assumption are, upon closer examination, not persuasive. Most fundamentally, we worry that the way in which Horwitz et al. conceptualize the relationship between genes and environments is not the best means of doing so for sociologists interested in engaging behavioral genetics. 相似文献

In this study, we explore how specific individual, family, and family-within-community characteristics, as well as aspects of in-home family therapy, relate to responses to treatment. The Child and Adolescent Functional Assessment Scale scores and Global Assessment of Functioning scores were used as outcome measures. Results revealed significant differences between pre- and post-scores for clients receiving in-home family therapy services, providing an initial indicator of treatment success. In addition, primary family caregiver social support, role performance in school/work, and self-harmful behavior were indicative of successful outcomes. Clients with higher problem levels had the greatest rates of change, and clients receiving more hours of services fared better in therapy. 相似文献

The relationship between interpersonal trust and membership in voluntary associations is a persistent research finding in sociology. What is more, the notion of trust has become a central issue in current social science theorizing covering such diverse approaches as transaction costs economics or cognitive sociology. In different ways and for different purposes, these approaches address the role of voluntary organizations, although, as this paper argues, much of this thinking remains sketchy and underdeveloped. Against an empirical portrait of this relationship, the purpose of this paper is to assess such theorizing. We first set out to explicate major approaches to trust in economics, sociology and political science, using the non-profit or voluntary organization as a focal point. We then examine the various approaches in terms of their strengths and weaknesses, and, finally, identify key areas for theoretical development. In particular, we point to the social movement literature, the social psychology of trust, and recent thinking about civil society. 相似文献

Much has been done to identify psychosocial factors influencing risk of vocational injury and prolonged disability. The purpose of this paper is to enhance the ability of injured workers to return to their prior worker role through the identification of the influencing psychosocial perceptions. Psychosocial perceptions may assist in the identification of negative or counterproductive factors that hinder the rehabilitative process. Identifying perceptions are individual centered and focused on the views of injured workers as they proceed through the transition in life following injury. Occupational therapists play a key role in the rehabilitative process of injured workers through enhancing the person-job-environment fit [4]. 相似文献
