At the core of migratory experiences lie key questions pertaining to one's emotional changing Self: the complexity of conflicting identities, feelings of (un)belonging, varying degrees of emotional place (un)attachment, and the fundamental (re)conceptualizations of ‘home’. Though well-studied from various angles, ‘home’ as an emotional concept in the context of generational family migration research has many gains yet to be made. Through an in-depth study on three generations of one author's own family, this paper provides personal insight into the intergenerational and emotional dimensions of this topic. Unanimously, the findings demonstrate that notions of ‘home’ as where family is remain predominant, with ties to transnationally dispersed family members rendering ‘home’ as multiple. Places of familial heritage further remain central in conceptualizations of ‘home’ through a retainment of cultural practices and values derived from familial homelands. Despite these cross-generational similarities, challenges and emotional uncertainties on the topic are seen to be increasingly prevalent in the youngest generation. Above all, interviewees' post-migration reflections demonstrate that such conceptualizations are intricate, relational and do not exist in an emotional vacuum. 相似文献

Reflexivity is the act of examining one's own assumption, belief, and judgement systems, and thinking carefully and critically about how these influence the research process. The practice of reflexivity confronts and questions who we are as researchers and how this guides our work. It is central in debates on objectivity, subjectivity, and the very foundations of social science research and generated knowledge. Incorporating reflexivity in the research process is traditionally recognized as one of the most notable differences between qualitative and quantitative methodologies. Qualitative research centres and celebrates the participants' personal and unique lived experience. Therefore, qualitative researchers are readily encouraged to consider how their own unique positionalities inform the research process and this forms an important part of training within this paradigm. Quantitative methodologies in social and personality psychology, and more generally, on the other hand, have remained seemingly detached from this level of reflexivity and general reflective practice. In this commentary, we, three quantitative researchers who have grappled with the compatibility of reflexivity within our own research, argue that reflexivity has much to offer quantitative methodologists. The act of reflexivity prompts researchers to acknowledge and centre their own positionalities, encourages a more thoughtful engagement with every step of the research process, and thus, as we argue, contributes to the ongoing reappraisal of openness and transparency in psychology. In this paper, we make the case for integrating reflexivity across all research approaches, before providing a ‘beginner's guide’ for quantitative researchers wishing to engage reflexively with their own work, providing concrete recommendations, worked examples, and reflexive prompts. 相似文献

Abstract. The sciences may be conceptualized as a hierarchy ranked by level of organization (e.g., many-body physics ranks above particle physics). Each science serves as an antidiscipline for the science above it; that is, between each pair, tense but creative interplay is inevitable. Biology has advanced through such tension between its subdisciplines and now can serve as an antidiscipline for the social sciences—for anthropology, for example, by examining the connection between cultural and biological evolution; for psychology, by addressing the nature of learning and the structure of the unconscious; for economics, by examining economically irrational behavior and by comparing economic activity in humans and other species. Sociology, concerned mainly with advanced literate societies, is relatively remote from the genetic basis of human social behavior. However, moving between biological and social levels of organization generates richness and points to new and unexpected principles. 相似文献

To examine to what degree argumentation skills are mastered by pupils who attend the vocational, general and academic streams in Dutch secondary education various subtests were constructed. The theoretical study of argumentation as exposed by Van Eemeren and Grootendorst was the basis for this test construction. In this article tests for the identification of singular, multiple and subordinate argumentation are described. Also an account is given of a pretest of these three subtests. 相似文献

Survey research with diverse cultural and ethnic minority groups is a complex and challenging endeavor that confronts the researcher with problems related to linguistic and conceptual equivalence and measurement as well as problems related to difficulties that respondents have with the sociocultural dimensions of the survey/interview process. One way to improve the quality of cross-cultural surveys and to insure that the findings are culturally relevant and accurate is to combine qualitative and quantitative methods. This paper proposes that certain qualitative techniques from cognitive science, specifically cognitive anthropology and cognitive psychology, are particularly well suited to being combined with survey research. These techniques provide information corresponding to the underlying thought processes of respondents and enable researchers to better understand how different cultural and ethnic groups construe the world. The information obtained can be used improve the formulation of survey questions, design and structure questionnaire formats to coincide with the way particular groups organize concepts, and help researchers understand difficulties respondents may have with the survey/interview process. In addition, the techniques produce data that are easily codifiable and more manageable than traditional qualitative techniques including participant observation and in-depth interviews. 相似文献

Expert research administrators responded to questions to determine to what degree they had postformal thinking skills. Postformal
theory suggests that the interpersonal and institutional complexity of work roles would make them likely to exhibit postformal
thought. The tests included a questionnaire about the use of postformal operations on the job, and thinking-aloud taped interviews
of responses to job-related and standard postformal problems. The respondents demonstrated the use of postformal thinking
operations on job-related tests and a more moderate degree of use on the standard problems. The results support prior research
and our working hypothesis that a high degree of interaction with people and complex problems is associated with adults' postformal
thought. 相似文献

This paper addresses some critical issues in the applicability of quantitative performance measures (including bibliometric,
economic, and co-occurrence measures) to the assessment of basic research. The strengths and weaknesses of metrics applied
as research performance measures are examined. It is concluded that metrics have a useful role to play in the evaluation of
research. Each metric employed, whether bibliometric, economic, co-occurrence, or others, brings a new dimension of potential
insight to the complex problem of research assessment. However, when used in a stand-alone mode, metrics can be easily misinterpreted
and result in misleading conclusions. Metrics should be an integral part of a more comprehensive approach to research evaluation,
in which the leading role is assumed by expert peer review. Under this structure, the reviewers must be broadly constituted,
so that the technical correctness of the research approaches being taken (doing the job right) can be evaluated by technical
experts and the correctness of the research target (doing the right job) can be evaluated as well. This comprehensive approach
insures quality in the implementation of existing research paradigms and allows the introduction of revolutionary new research
paradigms as well.

This issue, redesigned in a new format, marks the beginning of Volume 25, the beginning of the silver anniversary year of the Journal of Abnormal Child Psychology. Data were compiled from the first 24 volumes to study changes over time, and Pearson correlations were calculated to determine linear trends in the journal's development The number of articles per volume has doubled, from about 25 to 50. In recent years the first authors of articles were more likely to be located outside the U.S. (up from about 5% to about 25%). Also, in recent years the first authors of articles were less likely to be affiliated with nonmedical school university departments and more likely to be affiliated with medical schools or research institutes. An introduction to this special 25th anniversary issue is provided. 相似文献

The current literature suggests that individuals who chronically abuse alcohol exhibit a wide variety of cognitive deficits
resulting from cerebral dysfunction that is either directly or indirectly related to their alcohol consumption history. Cognitive
deficits have been hypothesized as having implications for standard alcohol treatment efficacy as they may directly affect
cognitively impaired individuals’ abilities to utilize various treatment modalities. Although evidence is accumulating that
suggests this is actually the case, the majority of alcohol treatment programs neither directly consider the impact cognitive
deficits have on treatment efficacy nor do they employ cognitive rehabilitation treatment strategies to remediate identified
cognitive deficits. Few studies exist that investigate the remediability of neurobehavioral deficits or the efficacy of integrating
cognitive rehabilitation strategies into more traditional treatment programs. Empirical investigations conducted to date indicate
that some cognitive deficiencies secondary to alcoholism are amenable to cognitive rehabilitation and this remediation is
generalizable. Rigorous well-controlled treatment outcome investigations are needed in order to determine the efficacy of
cognitive rehabilitation techniques in naturalistic settings using ecological outcome measures. Also, emphasis should be placed
on integrating cognitive rehabilitation techniques with proven efficacy into traditional alcoholism treatment programs. 相似文献
