Wing‐Chung Ho offers an extensive critique of what he calls our “radical constructionist approach to family experience,” questioning the theoretical validity and empirical utility of the research program. This article responds to the charges in the broader context of the program's constructionist analytics, discussing family's experiential location, organizational embeddedness, and the importance of ethnographic sensibility. A brief extract of situated talk and interaction is presented to illustrate the discursive complexity and institutional bearings of family as a category of experience. The conclusion takes up the issue of whether the program is radical in conceptualization and empirical realization. 相似文献

Plant protection products are used in agriculture to improve yields, but this use can cause contamination of the environment and is also likely to have adverse short and long term effects on agricultural workers. This poster describes a systems approach to reducing the risk of operator exposure to plant protection products through the introduction of ergonomics to the design process of large agricultural sprayers. 相似文献

Since the 1990s, ethnic studies and other components of multicultural education have been criticized by neo-conservative and assimilationist scholars who maintain that school diversity initiatives weaken national identity and fail to help students attain the knowledge, attitudes, and skills needed to function effectively in the national mainstream culture. The banning of ethnic studies courses in the Tucson (Arizona) Unified School District in the USA was a widely publicized manifestation of the neo-conservative response to multicultural school initiatives. This article describes neo-conservative critiques of ethnic studies, and argues that ethnic studies is an important component of US history that is required to help students become effective and thoughtful citizens in a democratic nation and global world. 相似文献

Summary. Despite its potential pitfalls, ecological inference is an unavoidable part of some quantitative settings, including US voting rights litigation. In such applications, the analyst will typically encounter two-way tables with more than two rows and columns. Although several ecological inference methods are currently available for 2×2 tables, there are fewer options for analysing general R × C tables, and virtually none that model counts as opposed to fractions. We propose a count R × C method that respects the bounds deterministically, that allows for complex relationships between internal cell quantities, that is easily extensible and that results from transparent assumptions. We study the method via simulation, and then apply it to an example that is drawn from the state of Texas relevant to recent redistricting litigation there. 相似文献

This article examines the relationship between refugees andthe regional dynamics of peacebuilding. It argues that recentapproaches to peacebuilding have adopted a narrow understandingof conflict. The article outlines the links between protractedrefugee situations and regional insecurity to argue that therelationship between peacebuilding and refugees goes beyondrepatriation. Instead, the presence of "spoilers" within therefugee-populated areas, the potential for early and forcedrepatriation, and the politicization of refugees while in exilehave all the proven potential to undermine peacebuilding efforts,while the experience of exile may enable refugees to contributeto the peacebuilding process. 相似文献

ABSTRACTApplying primary socialization theory to a sample of early adolescents from Nicaragua, this study examines direct and indirect associations between family bonding and adolescent alcohol use via substance specific prevention communication (SSPC) and adolescent efficacy. Early adolescents in 7th and 8th grades completed a self-report, cross-sectional survey. Structural equation modeling revealed that family expressiveness was significantly indirectly related to adolescent lifetime alcohol use through SSPC. Results are discussed in relation to primary socialization theory, family communication, and international substance use prevention efforts. This study provides supportive evidence for the important role of positive family communication as a protective factor for early adolescents in Nicaragua. 相似文献
