Terrestrial vertebrates in urban ecosystems: developing hypotheses for the Gwynns Falls Watershed in Baltimore,Maryland 总被引:2,自引:2,他引:0
We review the literature on terrestrial vertebrates in urban and urbanizing areas in terms of the new paradigm in ecology that focuses on the origin, spatial pattern, and current influences of habitat patches. Studies of terrestrial vertebrates have documented differences in species composition along an urban-rural gradient and have identified some of the key land use features associated with these differences. We use information from a database developed for the Gwynns Falls Watershed in Baltimore City and County, Maryland to demonstrate how a study of forest-dependent breeding birds could be used to identify mechanisms that account for differences in the bird communities of forest patches in urban areas, and to provide useful information to planners and managers involved in wildlife conservation and management. 相似文献

We conduct laboratory markets to evaluate the effects of consumer search costs on market performance. The primary research goal is to assess the behavioral relevance of Diamond's [1971] paradoxical conclusion that the injection of a small consumer search cost alters the equilibrium price prediction from competitive to monopoly levels. Although monopoly prices are not consistently observed, we find that search costs do tend to raise prices. Additional experimentation indicates that below-monopoly prices are not explained by buyer avoidance of high-pricing sellers, but that prices increase as search costs are raised. 相似文献

Despite drastic changes in the American family, a significant minority of Americans marry early. Using data from the National Longitudinal Study of Adolescent Health (N= 14,165), this study evaluates the prevalence and antecedents of early marriage in the United States. The results indicate 25% of women and 16% of men marry before age 23, and early marriage varies widely across a number of characteristics. Individuals who marry earlier are more likely to be from disadvantaged families, from conservative Protestant or Mormon families, to value their religious faith more highly, to have a high‐school diploma but a lower educational trajectory, and to cohabit before marriage. Scholars and policymakers interested in marriage should pay adequate attention to understanding and supporting these individuals’ marriages. 相似文献

Language theorists have often proposed lists of the defining properties of language. This account reviews some of these and offers as an alternative a three-item list consisting of instructional control, equivalence classes, and autoclitic processes.

The correlates of grievance initiation are described within the context of categories of relevant factors suggested by the
literature. The categories include environmental, management, union, union-management interaction, and employee factors. In
the environmental category, the literature indicates that technology effects provide substantial promise for the explanation
of grievances. Several important correlates of grievance activity are described in each of the other categories. Suggested
methodological improvements for future research include expanded sets of control variables, multiple industry data sets, greater
attention to grievance types, and the use of causal analytical techniques in longitudinal studies. Future research should
provide a better understanding of the effects of several variables, including technology, methods of grievance resolution,
workgroup cohesion, and fair representation requirements. It should also identify relationships that are specific to different
issues.
