The Search Institute framework for conceptualizing developmental assets was used in a longitudinal study of African American male youth involved in gangs or in community-based organizations (CBOs) serving youth. Analyses of intraindividual change indicated that individual and ecological assets are linked to positive developmental trajectories among these youth.  相似文献

This article examines the articulation between the senses of taste and sight through the representations of their organs, the tongue and the eye, in early modern Europe. The relationship between taste and sight first brings to mind gastronomical aesthetics, and the part played by the eye in the relish of beautifully presented dishes. The first part of this article is therefore devoted to exploring the taste of the eye (or the foretaste of sight) and highlights the harmony of taste and sight in early modern cuisine. However, the forms of reciprocity between taste and sight cannot be reduced to the sole figure of culinary aesthetics, which tends to blur the other multiple modalities that this sensorial association could reveal. The second part, the sight of the tongue (or the invisibility of taste), thus examines more complex layers of the relationship between the sense of sight and the taste organ, through a study of the representations of the tongue and of the gaping mouth in early modern visual culture. Drawing on early modern textual and iconographic resources and exploring: cookbooks; physiognomic works; conduct books; and also engravings and paintings related to the culinary arts, the seven deadly sins, and representations of madness and the fool in early modern visual culture, this essay argues that examining the representations of the sense organs is a suggestive way to explore the relationship between the senses.  相似文献

The aim of this article is to develop methodology for detecting influential observations in crossover models with random individual effects. Various case‐weighted perturbations are performed. We obtain the influence of the perturbations on each parameter estimator and on their dispersion matrices. The obtained results exhibit the possibility to obtain closed‐form expressions of the influence using the residuals in mixed linear models. Some graphical tools are also presented.  相似文献

How urban habitats contribute to biodiversity conservation is a key challenge in a rapidly urbanising world. Urban parks can provide important habitats for native species, but previous studies are geographically biased; fast growing megacities, in particular in South America, are clearly understudied. To assess habitat functions and underlying drivers in parks of Santiago de Chile, we analysed the assemblages of wild growing plant species in two ubiquitous park habitat types (grasslands, wooded areas) in 15 parks (150 plots) along an urban-rural gradient. We first used linear contrasts to compare species richness, beta diversity and the proportion of introduced species. We then tested for the explanatory value of environmental variables operating at different spatial scales (plot, park, urban matrix). Unlike in most previous studies, biodiversity patterns were not related to the position of the parks on the urban-rural gradient. Introduced species, mostly from Europe, generally dominated both habitat types (>90 %). Socio-economic (population growth or density), but not spatial, variables were retained in most models. Maintenance intensity was most influential in predicting species assemblages, complemented by park age in wooded areas. A high proportion of European grassland species indicates a trend of homogenisation in park grassland at a cross-continental scale. We conclude that habitat functions of urban parks for native species that have been mainly demonstrated for Europe cannot be generalised to South American megacities. This highlights the need for innovative and locally appropriate conservation approaches (e.g., re-introduction of native species) to foster biodiversity functions in urban parks of South American megacities.  相似文献
