The associations between menarcheal status and several child-rearing and outcome variables were examined for mother-daughter and father-daughter dyads. All variables were assessed with questionnaires as an extension of earlier observational studies. Analyses were conducted via multiple regression analyses wherein menarcheal status was treated as a continuous variable and was entered into the regression equation as a set of power polynomial terms. The results indicated that most of the significant relations occurred for the mother-daughter dyad, and most of these relations were curvilinear. When menarche occurs at or around the modal time, changes in parent-child relations may be best thought of as temporary perturbations, but when menarche occurs early the effects may persist.The research reported here was funded by Father Flanagan's Boys Home, Inc., and by a grant to the senior author from the John D. and Catherine T.

In economic hard-times, do Americans call for increases in governmental assistance, or do they clamor for declines in government assistance? We address this question by identifying the impact of state-level macroeconomic conditions on public support for social welfare spending. We analyze individual-level data from the 1984–2000 National Election Studies, combined with state-level macroeconomic indicators of inflation, unemployment, and productivity. We find that state-level inflation, not state-level unemployment nor state-level productivity, consistently and consequentially shapes citizens’ support for social welfare. With rising inflation, Americans become more supportive of means-tested social welfare spending. Our analyses generally reaffirm the value Americans place on the social welfare safety net, especially during times of economic duress. When the going gets tough, Americans reach out, rather than pull back.  相似文献

Family and dependency courts can become valuable partners in efforts to stem the tide of child maltreatment using a family‐centered strategy. Florida's response to a 2008 federal Child and Family Services Review included a commitment to implement family‐centered practice in child protection services and the courts that hear these cases. Evidence of this implementation was documented in a formative evaluation conducted in 2010 and 2011. Findings based on interviews with dependency judges, Children's Legal Services attorneys, and Guardian ad Litem volunteers provide useful insights on how these practices were perceived and implemented.  相似文献

This article contributes to existing explanations of political participation by proposing that citizens’ attitudes towards risk predict participation. I argue that people who are risk accepting participate in political life because politics offers novelty and excitement. Analyses of two independent Internet surveys establish a positive, significant relationship between risk attitudes and general political participation. The analyses also suggest that the relationship between risk attitudes and action varies with the political act: people who are more risk accepting are more likely to participate in general political acts, but they are no more or less likely to turn out in elections. Further analyses suggest that two key mechanisms—novelty seeking and excitement seeking—underlie the relationship between risk attitudes and political participation.  相似文献

Several parameters can delay the first arrival of flies on a corpse and the subsequent development of the larvae. This study focuses on the development of Lucilia sericata (Diptera: Calliphoridae) (Meigen, 1826) on household chemical‐contaminated substrates. bleach, perfume, hydrochloric acid, caustic soda, insecticide, mosquito repellent, and gasoline in quantities consistent with an amount that could possibly be spilled on a corpse were mixed with beef liver to simulate contaminated fleshes. Larvae were bred at 25°C on these media until emergence. Four developmental parameters were followed: survival rates, development times, sex ratios, and adult sizes. Hydrochloric acid, insecticide, and gasoline killed all larvae. In low quantities, caustic soda and mosquito repellent increased the development time and decreased the adult size. However, high quantities of these chemicals killed all larvae. Lastly, bleach and perfume did not affect the survival rate and barely impacted the development time or adult size. These results demonstrate common household products spilled on a corpse can strongly affect the development of Calliphoridae larvae. The effects of such products should be considered in forensic entomology cases.  相似文献

This analysis explores the role of city‐level and state‐level variables to explain why some cities make more progress on climate‐related policy implementation than others. Using multilevel modeling, we find little support for the influence of state factors on local government leadership among the 812 cities in the dataset, but local government institutional and community variables are strongly associated with climate policy initiatives. We argue for a rethinking of the notion of the limited and constrained city and suggest that, in the realm of climate protection and environmental policy, cities are leading a bottom‐up federalism. Moreover, where some political analysts and scholars have argued that climate protection and environmental policies may not be economically rational for cities to pursue, we theorize that cities are acting locally to further their self‐interest in an increasingly global economy.  相似文献
