The article deals with the question of how aggregated data which allow for generalizable insights can be generated from single-case based qualitative investigations. Thereby, two central challenges of qualitative social research are outlined: First, researchers must ensure that the single-case data can be aggregated and condensed so that new collective structures can be detected. Second, they must apply methods and practices to allow for the generalization of the results beyond the specific study. In the following, we demonstrate how and under what conditions these challenges can be addressed in research practice. To this end, the research process of the construction of an empirically based typology is described. A qualitative study, conducted within the framework of the Luxembourg Youth Report, is used to illustrate this process. Specifically, strategies are presented which increase the likelihood of generalizability or transferability of the results, while also highlighting their limitations. 相似文献

A sequel to the previous article “Roots of Excellence: The Releasing Effect of Individual Potentials through Educational Cultural Intervention in a Chinese School” (in press), the present study is on the unexpected reversal phenomena in the process of cultural intervention. The goal of the intervention is to construct the dynamics of Jiti (well-organized collective in Chinese) through creative activities to promote students’ development. In the intervention, the releasing effect (Wu et al. 2016) emerged as well, but the teacher’s concern about worsening discipline and academic performance evoked and reinforced his habitual notions and practices of education, turning the joint activities into a way of strengthening discipline. The energy that had been discharging at the beginning of the intervention was inhibited, so that many more problematic behaviors took shape. The whole class formed an inhibitory atmosphere, within which pupils formed self-defensive regulation strategies. By comparing with the productive collective in which intervention was effective and analyzing this unexpected reversal process, we can not only see pupils’ self-construction status in the inhibitory culture but illuminate the formation of the teacher’s resistance to educational and cultural transformation as well. Resistance is originated from teachers not being able to interpret pupils’ inner developmental needs but instead anxious about the ongoing problems. 相似文献

This paper examines the branding of ‘Canadian experience’ in Canadian immigration policy as a rhetorical strategy for neoliberal nation-building. Since 2008, the Canadian government has introduced an unprecedented number of changes to immigration policy. While the bulk of these policies produce more temporary and precarious forms of migration, the Canadian government has mobilized the rhetoric of ‘Canadian experience’ as a means to identify immigrants who carry the promise of economic and social integration. Through a critical discourse analysis of Canadian print media and political discourse, we trace how the brand of Canadian experience taps into the affective value of national identity in an era of global economic insecurity. We also illustrate how the discourse of Canadian experience (CE) remains ideologically deracialized, such that the government’s embrace of CE as an immigrant selection criterion dismisses the discriminatory effects that this discourse is shown to have for racialized immigrants in Canada. 相似文献

This multi-sited study in Canada, Mexico, and the Philippines examines how appraisals of English language competence transnationally mediate labor market entry for temporary migrant workers. Focusing on “low-skilled,” interactive service sector jobs, we show how border drawing along English language lines contributes to the regulation of access to global labor circuits and the segmentation of workers into occupational niches. Mediated by the migration industry, English linguistic capital acts as a marker of status and occupational desirability, shaping and reinforcing employer preferences and (re)defining the “properly embodied” service sector worker. This has implications for the social (re)organization of labor markets and the mobility options available to migrants and their sending states across sectors and scales. 相似文献

Chronicity, severity, and timing of maternal depressive symptoms: relationships with child outcomes at age 5 总被引:10,自引:0,他引:10
Brennan PA Hammen C Andersen MJ Bor W Najman JM Williams GM 《Developmental psychology》2000,36(6):759-766
The relationships between severity, chronicity, and timing of maternal depressive symptoms and child outcomes were examined in a cohort of 4,953 children. Mothers provided self-reports of depressive symptoms during pregnancy, immediately postpartum, and when the child was 6 months old and 5 years old. At the age 5 follow-up, mothers reported on children's behavior and children completed a receptive vocabulary test. Results suggest that both the severity and the chronicity of maternal depressive symptoms are related to more behavior problems and lower vocabulary scores in children. The interaction of severity and chronicity of maternal depressive symptoms was significantly related to higher levels of child behavior problems. Timing of maternal symptoms was not significantly related to child vocabulary scores, but more recent reports of maternal depressive symptoms were associated with higher rates of child behavior problems. 相似文献

When viewing ambiguous displays, observers can, via intentional efforts, affect which perceptual interpretation they perceive. Specifically, observers can increase the probability of seeing the desired percept. Little is known, however, about how intentional efforts interact with sensory inputs in exerting their effects on perception. In two experiments, the current study explored the possibility that intentional efforts might operate by multiplicatively enhancing the stimulus-based activation of the desired perceptual representation. Such a possibility is suggested by recent neurophysiological research on attention. In support of this idea, when we presented bistable apparent motion displays under stimulus conditions differentially favoring one motion percept over the other, observers' intentional efforts to see a particular motion were generally more effective under conditions in which stimulus factors favored the intended motion percept. 相似文献

The importance of scientific conflicts for theology andphilosophy is difficult to judge. In many disputes of significance, prominent scientists can be found on both sides. Profound philosophical and religious implications are sometimes said to be implied by the new theory as well. This article examines the dispute over natural selection between Richard Dawkins and Stephen Jay Gould as a contemporary instance of such a conflict. While both claim that profound philosophical conclusions flow from their own alternativeaccount of evolution, I suggest that the implication is not as great as is claimed and that the alleged implications have as much to do with their own perceptions of theology as with the actual theories themselves. Nevertheless, evolutionary theory is not irrelevant for theology. Theologians should be aware of the possible implications of evolutionary theory and at the same time theextent and limits of such implications. 相似文献

A therapy research team interviewed a therapist in the presence of a couple. Following each of six consecutive sessions with a couple, an interviewer posed questions to the therapist and couple. While one question was standard to each interview, other questions were generated by team members who tracked the entire process via live observation. These questions were directed first at the therapist, then at the couple, and then focused on therapeutic process and outcome. Findings of this process for the therapy system included decreasing the hierarchy within the client/therapist relationship; increasing the client ownership and energy in the therapy process; discovering the presence of parallel processes between the systems; and informing the direction of future therapy sessions. Practical, clinical implications are discussed for a variety of therapy settings. 相似文献

Confirmatory factor analysis and regression analyses of the Beavers Interactional Scales did not appear to support the model offered by its developers, namely, several specified family attributes contributing respectively to two global factors of Family Competence and Family Style. Moreover, regression analysis indicated that only three of 12 items predicted raters' assessments of Global Family Health, and one of seven items predicted Global Family Style. Individuals interested in the family dynamic centripetal/centrifugal might best think of that as a unitary entity and rate it accordingly. 相似文献
