For multivariate probit models, Spiess and Tutz suggest three alternative performance measures, which are all based on the decomposition of the variation. The multivariate probit model can be seen as a special case of the discrete copula model. This paper proposes some new measures based on the value of the likelihood function and the prediction-realization table. In addition, it generalizes the measures from Spiess and Tutz for the discrete copula model. Results of a simulation study designed to compare the different measures in various situations are presented.  相似文献

Market failures, government failures and some of the characteristics of both the poor and business actors as well as their environment can act as barriers preventing the poor from participating more actively in markets, both as consumers and as producers. Private actors ‐ including for‐profit and not‐for‐profit entities, often in partnership with the public sector ‐ have been able to mitigate some of these constraints through innovations that have helped to make markets more inclusive for the poor, enabling them not just to gain access, but also to participate in ways that enhance their economic empowerment and human development. This article identifies the strategies and innovations used and devises a possible typology for them.  相似文献

Planned unit developments (PUD) have been celebrated as one of the few means of escape from the stranglehold of Euclidean zoning but little is known empirically about their use and implementation. In this paper, I present quantitative data from Michigan exploring the factors affecting successful PUD implementation. Results indicate that citizen participation, emphasis of PUD regulations, PUD appeal and differences among key players during PUD review have significant impacts on successful PUD implementation. I also find that Michigan municipalities are more successful at achieving mixed-use, density, preservation, affordable housing, community facilities and design through PUDs than through other regulatory vehicles.  相似文献

Associations among (a) self-disclosures between early adolescent siblings, (b) emotional understanding, and (c) relationship warmth were investigated. Grade 5–6 children (M age = 11.5 years) were interviewed concerning the incidence of disclosures to closest-in-age siblings (20 = older, 20 = younger), feelings regarding disclosing (or not), and sibling relationship quality. Warmth was measured with the Sibling Relationship Questionnaire (Furman & Buhrmester, 1985) and emotional understanding was assessed with the Hypothetical Relationships Picture Task (adapted from Schneider, 1989, & Aquan-Assee, 1992). Hierarchical multiple regressions indicated self-disclosure was positively associated with feeling good about sharing and negatively associated with reports of not trusting or not receiving emotional support from their sibling. Sibling relationship warmth was a key characteristic associated with both emotional understanding and self-disclosure; female target children demonstrated greater emotional understanding. Warmth, but not emotional understanding, was associated with self-disclosure. Findings are discussed in light of the importance of links between affective relationships and children's social-emotional understanding.  相似文献

This article seeks to identify factors associated with the formation and development of nonmetropolitan destinations for older in‐migration, thereby explaining why some U.S. counties are more likely than others to be nonmetro retirement destinations. We contend that most nonmetro retirement destinations are established and developed over time through a path‐dependent process. When amenities are commodified as recreation and tourism, migration streams tend to be established that ultimately produce sustained in‐migration of older persons to selected destination communities. We use data from a variety of official sources and a spatial statistics methodology to examine intercounty variability in net migration rates at ages 60–74. Our findings are consistent with the aforementioned path‐dependent development framework. Counties with a long history of population growth, previous experience attracting older in‐migrants, attractive natural amenities, and a developed recreation and tourism industry are those most likely to be retirement‐age migration destinations. In contrast, agricultural heartland and relatively large population size are associated with lower rates of older in‐migration. Older in‐migration should be seen as neither a panacea for strapped rural communities nor a “pensions and care issue.” Older migrants can be “gray gold,” but they can also pose challenges, such as possibly increased demand for public services as they age in place.  相似文献
