In contrast to younger populations, little attention has been paid to the increase in seniors using Internet-based venues to find relationships and the potential risk for adverse outcomes this poses. This study examined data collected via an online survey from 45 ethnically diverse women aged 50+ “seeking relationships” on MySpace. The majority of women reported a relationship with someone they met online (85%). They also reported experiencing adverse events including financial exploitation (40%), threats (55%), and physical harm (38%) by someone they met online at levels greater than traditional relationship seeking in the general population. Directions for future research are explored.  相似文献

This paper gives an account of working-class studies as it has developed in the USA and UK. It includes a comparative assessment of ways in which the working-class and class analysis appear within academe. This argues that the different role played by social classes in the post-war settlement and its subsequent breakdown can account for divergent fortunes of class analysis in response to similar developments. The paper unpacks some of the opportunities and threats to further development of working-class studies in the UK. It is argued that the field needs to be developed in a way that is reflexively self-critical and avoids reproducing middle-class experience as universal. However, it notes the challenge of opening up space for the working class within the academy, particularly given the problem of the institutional embodiment of class together with the rigid framework of higher education in the UK.  相似文献

Summary. The problem of analysing longitudinal data that are complicated by possibly informative drop-out has received considerable attention in the statistical literature. Most researchers have concentrated on either methodology or application, but we begin this paper by arguing that more attention could be given to study objectives and to the relevant targets for inference. Next we summarize a variety of approaches that have been suggested for dealing with drop-out. A long-standing concern in this subject area is that all methods require untestable assumptions. We discuss circumstances in which we are willing to make such assumptions and we propose a new and computationally efficient modelling and analysis procedure for these situations. We assume a dynamic linear model for the expected increments of a constructed variable, under which subject-specific random effects follow a martingale process in the absence of drop-out. Informal diagnostic procedures to assess the tenability of the assumption are proposed. The paper is completed by simulations and a comparison of our method and several alternatives in the analysis of data from a trial into the treatment of schizophrenia, in which approximately 50% of recruited subjects dropped out before the final scheduled measurement time.  相似文献

This article explicates the concept of respect as philosophers discuss and utilize it. After identifying the main questions about respect which philosophers have raised and addressed, including questions about the nature, importance, objects, grounds, psychological and behavioral elements, and implications of respect, I sketch an account of the most general elements of the attitude of respect and identify different kinds of respect and their connections to and differences from similar attitudes such as esteem and honor. I then discuss the most influential account of respect for persons, that of Immanuel Kant. The final section explores the importance of respect in moral, social and political life and in moral, social, and political theory, and highlights some implications for issues in applied ethics and social and political theory.  相似文献

The present study explores the relationship between the characteristics of youth in foster care and youth attitudes about mentoring and adoption. Using a positive youth development framework, the study examines the relationship between youth risk and resilience variables (youth risk scores, youth assets and youth perception of control) and youth attitudes about mentoring and adoption. Data were collected from 54 youth, ages 10 to 17 years, through intake interviews and surveys. Participants were 25 male and 29 female adolescents; 33 were Caucasian and 21 were African American. Overall, the youth had positive attitudes about both mentoring and adoption, with Caucasian youth having more positive attitudes than African American youth. A 2 × 2 (Gender × Race) analysis of variance revealed greater feelings of control for male and Caucasian youth. Hierarchical regression analyses revealed that the youths' perceptions of their strengths and assets were related to how positively they viewed mentoring and adoption.  相似文献

Photovoice is part of the growing use of participatory research approaches with people with intellectual disabilities. In this paper we explore the process, opportunities and challenges associated with the use of photovoice with people with intellectual disabilities, illustrated through a research project entitled ‘This Is Me’. Photovoice requires researchers to share power and control in the research process and to tolerate uncertainty. Large investments in time and money are also required. These challenges, however, are outweighed by the benefits of the use of photovoice with people with intellectual disabilities. Photovoice creates a space where people with intellectual disabilities can meaningfully participate and exert control in the research process, and as such is an empowering experience. As a participatory research approach, photovoice is accessible and offers the opportunity for people with intellectual disabilities to develop new skills, confidence and experience inclusiveness in their own terms.  相似文献

The ideal of scientific progress is that we accumulate measurements and integrate these into theory, but recent discussion of replicability issues has cast doubt on whether psychological research conforms to this model. Developmental research—especially with infant participants—also has discipline‐specific replicability challenges, including small samples and limited measurement methods. Inspired by collaborative replication efforts in cognitive and social psychology, we describe a proposal for assessing and promoting replicability in infancy research: large‐scale, multi‐laboratory replication efforts aiming for a more precise understanding of key developmental phenomena. The ManyBabies project, our instantiation of this proposal, will not only help us estimate how robust and replicable these phenomena are, but also gain new theoretical insights into how they vary across ages, linguistic communities, and measurement methods. This project has the potential for a variety of positive outcomes, including less‐biased estimates of theoretically important effects, estimates of variability that can be used for later study planning, and a series of best‐practices blueprints for future infancy research.  相似文献

To address the risk posed to human health by the consumption of VTEC O157 within contaminated pork, lamb, and beef products within Great Britain, a quantitative risk assessment model has been developed. This model aims to simulate the prevalence and amount of VTEC O157 in different meat products at consumption within a single model framework by adapting previously developed models. The model is stochastic in nature, enabling both variability (natural variation between animals, carcasses, products) and uncertainty (lack of knowledge) about the input parameters to be modeled. Based on the model assumptions and data, it is concluded that the prevalence of VTEC O157 in meat products (joints and mince) at consumption is low (i.e., <0.04%). Beef products, particularly beef burgers, present the highest estimated risk with an estimated eight out of 100,000 servings on average resulting in human infection with VTEC O157.  相似文献
