The authors of this article identify and discuss some of the practical and ethical issues of qualitative research with children. The problems are illustrated through a research study about children's experience of asthma, and the way in which they perceive and interpret their condition. It is shown that social research with children has inherent difficulties relating to access, ethical and developmental issues. Researchers do not only have to gain parental permission but also want the child to enter the research voluntarily. Because of the children's stage of development and the asymmetrical relationship between researcher and informants, adequate safeguards and awareness of these problems are essential.  相似文献

Mr. Holloway joined the Gulf Oil Corporation in 1939. His previous publications are in the fields of chemical engineering, statistics and computing.He is now the Senior Adviser on Planning Systems and member of Gulf's European Planning Council.The paper presents the author's view that linear programming is an efficient vehicle for long range planning, that it is more comprehensive and when properly structured requires no more computer time than the perhaps more conventional simulation models.Further, that it has the great advantage that the planner himself can control not only the data content of his model, but can also control the way in which the data is treated within the model even to the extent of making drastic matrix changes.  相似文献

This article describes the findings and examines the issues arising from a small-scale investigation into the experience of higher education from the perspective of disabled students at a university in the United Kingdom, and makes recommendations for policy and practice. Methodology involved semi-structured interviews with participants to reveal individual experience and analysis of relevant documentation from the university to examine the rhetoric underlying their experience. Factors that create a positive experience for disabled students, and those which effect discriminatory practice and marginalisation are identified. The implications of the findings for policy and practice are discussed, and conclusions drawn including: the need for a central policy which supports the philosophy of an accessible learning environment for all students; central co-ordination to implement the policy with practical guidelines to departments; ongoing monitoring and evaluation procedures which involve disabled students; staff training and awareness; student advocacy.  相似文献

Young men who have sex with men (YMSM) have higher rates of cigarette smoking than their heterosexual counterparts, yet few studies have examined factors associated with cigarette smoking among YMSM. The present study sought to understand how different types of gay community connection (i.e., gay community identification and involvement, gay bar/club attendance) were associated with smoking among YMSM recruited through venue-based sampling in Los Angeles, California (N = 526). Structural equation modeling was used to isolate direct and indirect effects of gay community connection on smoking through cognitive and psychological mediators (i.e., psychological distress, health values, internalized homophobia). Findings indicate YMSM cigarette smoking prevention and intervention must be tailored to address the direct and indirect influences of the gay community.  相似文献

School-based child sexual abuse (CSA) prevention programs have proliferated since beginning over 30 years ago. Research on program effectiveness has emphasized summative outcomes while under-reporting implementation and process fidelity, limiting reliable comparisons across programs and populations. External validity is further limited by racially and economically homogenous samples, or a failure to report such demographics. This article presents data from a CSA prevention program delivered to 2nd and 3rd grade public school children. A formative concept and item level analysis on the Children’s Knowledge of Abuse Questionnaire at baseline and four week follow-up, as well as fidelity and implementation data, are reported. Results show that children learn and retain certain concepts, but vary widely in knowledge across items. This sample of low-income, minority children also show lower baseline and “learned” abuse prevention knowledge compared to published norms, which is not attributed to implementation variability. These data give critical insight into workshop effectiveness that is masked in summative reporting, yet essential to adapting and strengthening school-based CSA programs. Knowing the long-term consequences of adverse childhood experiences and disparate health outcomes linked to race and socioeconomic status, it is imperative to adequately assess CSA prevention program impact across diverse populations.  相似文献

Research in Australia on the digital divide has concentrated on the disparities that exist between metropolitan and non‐metropolitan areas, and supply side solutions rather than demand side barriers. This paper attempts to add to our understanding of the digital divide in Australia by examining Internet usage in Western Sydney. A survey of over seven hundred households was conducted to analyse disparities in Internet access within a metropolitan area, as well as to add to debates surrounding demand side barriers that inhibit the ability of individuals to access the Internet. The findings suggest that age, income and employment status are significant contributors to demand side barriers. The results confirm evidence from overseas that disparities in online access exist within metropolitan areas. This suggests that more local level information is required so that programs aimed at addressing disparities in Internet access are targeted to the most appropriate areas and individuals, and the circumstances and preferences of those areas and individuals.  相似文献

Gender asymmetry in mixed-race heterosexual partnerships and marriages is common. For instance, black men marry or partner with white women at a far higher rate than white men marry or partner with black women. This article asks if such gender asymmetries relate to the racial character of the neighborhoods in which households headed by mixed-race couples live. Gendered power imbalances within households generally play into decisions about where to live or where to move (i.e., men typically benefit more than women), and we find the same in mixed-race couple arrangements and residential attainment. Gender interacts with race to produce a measurable race-by-gender effect. Specifically, we report a positive relationship between the percentage white in a neighborhood and the presence of households headed by mixed-race couples with a white male partner. The opposite holds for households headed by white-blacks and white-Latinos if the female partner is white; they are drawn to predominantly nonwhite neighborhoods. The results have implications for investigations of residential location attainment, neighborhood segregation analysis, and mixed-race studies.  相似文献
