受访者推动抽样：研究隐藏人口的方法与实践

“隐藏人口”的特点是规模较小且成员一般不愿暴露身份，因此很难使用常规抽样方法对其进行研究。近年来出现了一种新的研究隐藏人口的方法——受访者推动抽样（RDS)方法，该方法在传统“雪球抽样”方法的基础上，结合社会网络分析的理论和方法，使研究者有可能根据样本对总体特征做出合理的推论。本文对RDS方法的理论渊源、基本思路、主要操作步骤和原理进行了简要介绍，并探讨了在实际操作过程中应注意的问题。     

Using complexity theory in kinship practice

This reflective discussion draws on data from a collaborative enquiry into kinship or family and friends practice. It introduces perspectives from complexity and chaos theory as a way of re‐examining the challenges of kinship practice. The discussion highlights the enduring challenges for practitioners, not least, managing anxiety and uncertainty, sustaining continuity and containment, becoming experienced and taking account of the complex developmental needs of the children and their families. The discussion particularly raises questions about appropriate settings for practitioners to undertake such a demanding area of child and family social work.

Department of Health Research Overviews – Past, Present and Future: An evaluation of the dissemination of the Blue Book, Child Protection: Messages from Research

Since 1985 the Department of Health has been providing child care research overviews as a means of bringing together the findings of its funded research programmes. With each successive publication a pattern of design and dissemination has emerged. This is illustrated by Child Protection: Messages from Research ( Department of Health 1995 ), an overview of 20 studies of child protection. It included an introductory essay, summaries of each project and a set of 'True for Us' exercises. Publication was followed by national seminars and widespread distribution of free copies. Given the substantial investment, it seems timely to assess the impact of the dissemination process in terms of reaching and affecting practice. The survey sought to assess awareness, use and opinions of the report from social services, education and health professionals. It consisted of questionnaires administered by post and telephone calls to a representative sample of 600 professionals working in child protection, 292 of whom replied. The results demonstrate that the book is very well known among most professionals working in child welfare, particularly in social services, and is perceived to have affected the practice of over half of the respondents. The study supports the structure adopted for the report but suggests further benefits in employing a variety of dissemination strategies for different professional groups. Finally, the paper discusses the relationship between overviews and evidence-based services.

An exploratory study of family‐centred help‐giving practices in early intervention: families of young children with autism spectrum disorder

The purpose of this exploratory qualitative study was to investigate the early intervention (EI) experiences of mothers who have a young child at risk for autism spectrum disorder. Data were collected through observations, interviews and document analyses. Results of the study suggest (i) interpersonal skills of practitioners and provisions for family choice and collaboration lead to positive experiences for mothers; (ii) asset‐based attitudes lead to family progress and competence; (iii) effective partnerships are developed through supportive provider communication techniques; and (iv) satisfaction with EI services results from practitioner responsiveness to help families access resources and facilitate child development.     

Critical Realism,Dialectics, and Qualitative Research Methods

Critical realism has been an important advance in social science methodology because it develops a qualitative theory of causality which avoids some of the pitfalls of empiricist theories of causality. But while there has been ample work exploring the relationship between critical realism and qualitative research methods there has been noticeably less work exploring the relationship between dialectical critical realism and qualitative research methods. This seems strange especially since the founder of the philosophy of critical realism, Roy Bhaskar, employs and develops a range of dialectical concepts in his later work in order to extend the main tenets of critical realism. The aim of this paper is to draw on Bhaskar's later work, as well as Marxism, to reorient a critical realist methodology towards a dialectical approach for qualitative research. In particular, the paper demonstrates how dialectical critical realism can begin to provide answers to three common criticisms made against original critical realist methodology: that the qualitative theory of causal powers and structures developed by critical realists is problematic; that critical realist methodology contains values which prove damaging to empirical research; and that critical realists often have difficulties in researching everyday qualitative dilemmas that people face in their daily lives.     

Protecting the Public's Health in An Era of Bioterrorism: The Model State Emergency Health Powers Act

During the fall of 2001, public health law scholars at the Center for Law and the Public's Health at Georgetown and Johns Hopkins Universities were asked by the Centers for Disease Control and Prevention (CDC) and a series of national partners to develop the Model State Emergency Health Powers Act (MSEHPA). The MSEHPA provides a series of modern powers for states to consider in responding to catastrophic public health emergencies, including bioterrorism events. Since December 2001, provisions based on the MSEHPA have been introduced in nearly 40 states and passed in 20. Underlying the development of the act is a long-standing debate between legal and ethical scholars and law- and policymakers as to the appropriate ways to balance individual and communal rights. The drafting challenge was to create a comprehensive model law that provides adequate powers to protect the public's health while also respecting individual and group rights. The MSEHPA empowers public health agents with broad authority and simultaneously limits the exercise of power in time, duration, and scope to accomplish communal goals of abating serious public health threats. Coercive public health powers, particularly isolation and quarantine, are exercised on a temporary basis, only so long as are reasonably necessary and only among persons who justifiably may pose a risk to others because of their contagious conditions. Individual rights to contest the coercive use of public health powers, even during an emergency, are secured.
