This exploratory study examines the effects of rural and urban population change on forest cover at the local level across the southern United States. Using county‐level data from the National Land Cover Database and other U.S. government sources, we regressed the total area of forest cover on rural and urban population size in spatial panel models with two‐way fixed effects. When we controlled for several other factors, including the number of forestry operations at the county level, regression results indicate that urban change had no effect, but rural population size was positively related to total forest area, and this effect was most pronounced in and around Georgia. Thus, in areas of the southern United States, rural growth was associated with afforestation, not deforestation. We speculate on how this unusual finding contributes to the debate between ecological modernization and urban political economy implicated in previous cross‐national research. 相似文献

Using a long panel of roll call voting data, I find that “flip‐flopping” senators face significant electoral costs when changing positions. In models of electoral competition, as the costs to candidates changing position approach zero, the equilibrium prediction is the convergence of platforms. Such convergence is at odds with empirical observation. Using a dynamic, structural model of candidate positioning, I identify the nature of the costs associated with changing position that may result in such non‐convergence. (JEL D72, C61, H11) 相似文献

It has been argued that transracially adopted children have increased risk of problems related to self-esteem and ethnic identity development. We evaluated this hypothesis across four groups of transracial adoptees: Asian (n = 427), Latino (n = 28), Black (n = 6), mixed/other (n = 20), and same-race White adoptees (n = 126) from 357 adoptive families. No mean differences were found in adoptees’ ratings of affect about adoption or of curiosity about birth parents. Some differences were found in general identity development and adjustment. There were notable differences in communication about race/ethnicity across groups and between parent and child report. 相似文献

Estimating the prevalence of adolescent gambling disorders: A quantitative synthesis and guide toward standard gambling nomenclature 总被引:6,自引:0,他引:6
Dr. Howard J. Shaffer Matthew N. Hall 《Journal of gambling studies / co-sponsored by the National Council on Problem Gambling and Institute for the Study of Gambling and Commercial Gaming》1996,12(2):193-214
This article reviews the extant published and unpublished studies that estimate the prevalence of adolescent gambling problems in North America. The nine nonduplicative studies identified by our literature search included data collected from more than 7700 adolescents from five different regions of the United States and Canada. In addition to comparing the conceptual and methodological differences that exist among these studies, this article employed a meta-analytic strategy to synthesize prevalence estimates from the existing studies. This analysis revealed that within a 95 percent confidence interval, between 9.9% and 14.2% of adolescents are at risk of developing or returning to serious gambling problems. Similarly, between 4.4% and 7.4% of adolescents exhibit seriously adverse compulsive or pathological patterns of gambling activity. Finally, the discussion proposes a generic multi-level classification scheme to reconcile the divergent classification methods and data reporting strategies. This new multi-level approach to reporting gambling prevalence will facilitate interstudy comparisons among existing estimates of gambling prevalence and help to provide a general data reporting system for future research. 相似文献

Unexpected events such as environmental catastrophes capture wide public attention. Soon after five major shocks—Three Mile
Island, Love Canal, Bhopal, Chernobyl, and the Exxon Valdez oil spill—Congress voted on new risk regulation. This paper conducts
an event study to test whether individual congressional representatives were “shocked” by these environmental disasters into
increasing their probability of voting in favor of risk legislation. On average, representatives were less likely to vote
in favor of bills tied to these five events. Significant heterogeneity in representatives’ responses to these shocks is documented.
Liberal Northeast representatives were most likely to increase their pro-environment voting in the aftermath of these shocks.

Revolution is the triumph of freedom; its organization is based on spontaneity, not on the dictates of a “hero” who imposes himself through violence. It is a continuous and systematic elevation of a people, following the lines of a hierarchy, and creating for itself one by one the organs that the new social life demands. 相似文献

Objective. This article investigates how race/ethnicity is associated with specific types of violent crime such as killings between intimates, robbery homicide, or drug‐related killings. We extend the study of the role of race and ethnicity for violence by examining five ethnic/immigrant groups, including the Mariel Cubans—a group singled out by many as particularly drug‐crime‐prone. Methods. Using 1980 through 1990 homicide data for the City of Miami, we use multinomial logistic regression to examine the association between race/ethnicity, nativity, and several types of homicide motives. Results. Contrary to popular expectations, ethnicity and immigration status rarely play a role in the types of homicide involvement of victims or violators. Incident characteristics, such as multiple offenders, or gender and age, were consistently more important influences in shaping homicide circumstances. Conclusions. The analyses revealed few significant relationships between immigration status and homicide motives, suggesting that immigrant groups like the Marielitos have more in common with native groups' experiences of criminal violence than is commonly assumed. 相似文献
