Employed individuals from a range of jobs (n=18) were interviewed using a repertory grid technique, to explore the criteria they used to distinguish between different jobs. The concepts of 'a good job' and 'a job good for health' were also discussed. Interactions with others and the job itself were the most commonly used criteria and were also the most common features of a 'good job'. Pay and security were mentioned frequently but were less important when comparing jobs and when defining a 'good job'. Physical activity was rarely associated by interviewees with a 'good job' but was frequently associated with a 'job good for health'. A comprehensive definition of a 'good job' needs to take all these factors into account. 相似文献

Childbearing behavior in East Asian countries has changed rapidly during the past half century from an average of five to seven children per family, to replacement-level fertility, and subsequently to unprecedentedly low levels, the lowest in the world. This article analyzes fertility trends in Hong Kong, Japan, singapore, south Korea, and Taiwan using cohort fertility data and methods, then examines social and economic causes of the childbearing trends, and surveys policies pursued to reverse the fertility trends. Postponement of childbearing started in the 1970s with continuously fewer delayed births being "recuperated," which resulted in ultra-low fertility. A rapid expansion of education and employment among women in a patriarchal environment has generated a stark dilemma for women who would like to combine childbearing with a career. Policy responses have been slow, with a more serious attempt to address issues in recent years. Thus far public and private institutions are not devoting sufficient attention to generating broad social change supportive of parenting. 相似文献

This article uses a case study of the Niagara Movement, which functioned from 1905–1910, to demonstrate that the use of prosopography (collective biographies) is a propitious methodological tool, particularly for those interested in the social-psychological analysis of movement actors within networks. I present a prosopography of the founders of the Niagara Movement. Learning more about the identity of political actors provides clues to the ways strategic choices are made and how collective action frames are developed. The prosopography of the Niagara Movement also provides theoretical insights into discursive processes that are often lost in studies of long movement trajectories. I analyze potential explanations for the absence of organizations such as the Niagara Movement from the civil rights canon, and, through an analysis of talk as a resource for mobilization, pinpoint directions for future researchers interested in micro theories of mobilization. 相似文献

Explaining the survival and failure of firms is an important issue for researchers and managers of firms in society. Ecological approaches to the study of firms have existed for over 100 years, and have been increasingly popular during the past 40 years, especially since the pioneering works of Hannan and Freeman on one hand, and Aldrich on the other. This paper, in keeping with recent developments elsewhere in mainstream ecology outlines and positions the theoretical and philosophical foundations of an alternative ecological approach, autecology, that has not yet been formulated for the study of firms. The autecological approach affords the individual firm more autonomy in creating its own future evolutionary trajectory. The idea of an ecological complex is developed to provide clear focus on what is central to the application of autecology to the study of firms. The paper also considers several emergent research opportunities that highlight the potential value of employing an autecological approach to the study of firms. 相似文献

The emergence of positive psychology has generated increased interest about the correlates of positive psychological functioning. Researchers have identified and studied various positive psychological constructs (e.g., hope, optimism, self-efficacy, gratitude, and life satisfaction) and found them to covary and to be positively associated with optimal human functioning and negatively associated with mental illness. This study of 528 college students examined the co-occurrence of selected positive psychological traits and explored their relations with a proposed second-order latent construct called covitality and with psychological well-being. Structural equation modeling examined each first-order positive psychology construct related to the second-order concept of covitality. Findings supported the second-order latent factor model of covitality, which was also significantly related to indicators of psychological well-being. Implications for theory development related to understanding positive human resources and applications within the context of college student populations are discussed. 相似文献

This article charts the response of social work educators in addressing HIV–AIDS. Based at the University of the West Indies in the Republic of Trinidad and Tobago, the faculty within the Social Work Unit developed a model of teaching, research and practice that was innovative and transcended cultural, geographical and professional boundaries. The model has contributed a lasting legacy of knowledge and culturally relevant practices to enhance the capacity and effectiveness of social workers working with people living with HIV–AIDS (PLWHIV). Inherent in the propositions that underpinned the model was a belief in the role of education in alleviating psychosocial and other impacts of social problems. This article describes this unique initiative and discusses its relevance to current social work practice and the implications for contemporary social work education. The authors argue that while social work draws on a common body of knowledge, an established set of professional skills and a universal code of values, these central tenets of the profession should not be regarded as concrete and fixed but must be figured and reconfigured as needed to address emerging contemporary problems and their specific sociocultural manifestations. 相似文献

1. Postpartum depression has been used as a catchall phase for many postpartum emotional symptoms. Categorizing a number of diverse disorders under one title has resulted in an inability to identify who is most at risk for developing postpartum problems. 2. The postpartum period is a particularly vulnerable period for depression, despite the fact that it is perceived as a time of joy and emotional well-being. 3. By increasing awareness among all health care professionals who care for women during the period following childbirth, postpartum psychiatric disorders can be identified early and treated correctly. 4. Limiting postpartum psychiatric disorders to postpartum depression may result in limited or inappropriate treatment options. 相似文献

k-POD: A Method for k-Means Clustering of Missing Data 总被引:1,自引:0,他引:1
The k-means algorithm is often used in clustering applications but its usage requires a complete data matrix. Missing data, however, are common in many applications. Mainstream approaches to clustering missing data reduce the missing data problem to a complete data formulation through either deletion or imputation but these solutions may incur significant costs. Our k-POD method presents a simple extension of k-means clustering for missing data that works even when the missingness mechanism is unknown, when external information is unavailable, and when there is significant missingness in the data.[Received November 2014. Revised August 2015.] 相似文献
