THE ERS Standards, together with those of the Joint Committee, symbolize a commitment to the professionalization of evaluation. The two sets of standards, however, differ on at least five important dimensions: the perceived linearity of evaluation activities; preferred and permitted approaches (with one set heavily favoring quantitative/experimental approaches over any others); the purposes of evaluation; obligations to clients and stakeholders; and whether or not social science can be value-free (objective). Because these fundamental assumptions are so divergent, the possibility of combining or effecting a compromise between the two sets appears unlikely at this time.  相似文献

To date, tests of the minority-group status hypothesis relating to fertility have embodied a number of shortcomings—often in the nature of the data used, sometimes in the techniques of analysis, as well. Australian data particularly suited to a test of this hypothesis support it, but only when minority status is combined with pronatalism. In the absence of pronatalism, minority/majority fertility differences can instead be readily accounted for in terms of group differences either in socioeconomic composition or in the distribution of more specifically individual attributes.  相似文献

The construction industry involves many participants with different perspectives and requirements. Contracts can provide significant value, and yet ineffective contract management frequently leads to disputes. In practice, contracts are hardly reviewed, and contract management is limited. This study aims to investigate how firms can improve their internal processes relating to knowledge management (KM) through effective contract management to aid construction practitioners in managing contract disputes and changes. Using a questionnaire survey and a workshop involving experienced industry practitioners and researchers, the findings reveal that project- and individual-level implementation of KM processes is stronger than at the organizational level, and also there are substantial human resources (HR) practices that support contractual KM. Workshop participants believe efficient and effective KM can minimise losses from contract changes and disputes. A construction contract management process framework, a 19-step benchmarking model for contract management and a construction planning checklist for contractors are proposed.  相似文献

This study examined the temporal relation between self‐competence (academic, social, athletic, physical appearance, and close friend) and depressive symptoms in a large, diverse community sample of 636 adolescents. Surveys were administered to all 10th‐ and 11th‐grade students at participating high schools at baseline (mean age = 16.10, SD = .71) and 1 year later. Girls reported higher levels of self‐competence in close friendships and more depressive symptoms, whereas boys reported higher levels of self‐competence in athletics and physical appearance. However, there were no gender differences in the associations between self‐competence and depressive symptoms. Results from autoregressive, cross‐lagged path analyses indicated that depressive symptoms predicted self‐competence more consistently than self‐competence predicted depressive symptoms during middle–late adolescence. Implications for prevention are discussed.  相似文献

Abstract

In this essay, I argue for “fugitive gardening” as a form of “poaching” or “resignifying,” a radical appropriation of hegemonic spaces and practices that both deconstructs the logics of mastery and hygienic possessiveness that underpin colonial culture, and articulates what we might call a fugitive ecology: a dispossession of self in relation to the environment, a refusal to conceive of land, soil or planet in terms of property. Fugitive gardening sets itself in opposition to the prisons, camps and forts that index South African political history, restorying place, environment, and the self as grounds for community formation, dialogue and cooperation. Through readings of Coetzee’s Life & Times of Michael K and other examples of literary and material gardening, I show how such cultivation represents a gesture of belonging in a context where such claims are revolutionary, even treasonous; but unlike farm, fort or prison, fugitive gardening stakes a claim to belonging without possession, home without property and ecological care without an investment in the future. As such, gardening entails a very different understanding of self in relation to place, to nature and to future generations, and a reconceptualisation of narrative and language as representational modes.  相似文献

African Americans with mental health problems consult a variety of sources for assistance. Most studies report a preference for informal sources rather than professional sources of help with mental health concerns. While it is clear that African Americans seek help from both informal and professional sources, less known is whether there are unique subpopulations of African Americans that can be defined by their support and services use. Given the importance of religion in the lives of African Americans, it also important to understand the role of religious involvement in determining help-seeking behaviors. This study used latent class analysis and data from the National Survey of American Life (n = 1315) to identify distinct profiles of help-seeking behavior among African Americans with mental health disorders defined by informal (e.g., clergy, family, and friends) and professional sources (e.g., health and mental healthcare providers) of support and services. Findings revealed two help-seeking classes: Low Use/Informal Support (95%) and High Use/All Support (5%). Low subjective religious involvement was associated with membership in the Low Use/Informal Support class. High non-organizational religious involvement was associated with membership in the High Use/All Support class. No associations between demographic characteristics were found between the two classes. Findings highlight heterogeneity in help-seeking behavior among African Americans and the importance of considering multiple domains of religious involvement in influencing these behaviors. Findings highlight the importance of collaborative efforts between religious institutions, health and mental healthcare providers, family and friendship networks in the delivery of mental health care to African Americans.  相似文献

This study examines the demographic correlates of depressive symptoms, serious psychological distress (SPD), and major depressive disorder (MDD; 12-month and lifetime prevalence) among a national sample of African American men. Analysis of the National Survey of American Life (NSAL) data set provides first-time substantiation of important demographic differences in depressive symptoms (measured by the Center for Epidemiological Studies Depression scale [CES-D]), SPD (measured by the K6), and 12-month and lifetime MDD among African American men. Findings illuminate the heterogeneity within the African American male population. Findings also demonstrate the need for additional research focusing on within-group differences and a comprehensive research and mental health promotion agenda that recognizes the importance of improving access to education and employment and promoting healthy coping behaviors, while acknowledging the larger social context in which African American men live.  相似文献
