This article reviews the existing literature on young disadvantaged fathers' involvement with children. It first outlines the predominant theoretical perspectives regarding father involvement among resident (married and cohabiting) biological fathers, resident social fathers (unrelated romantic partners of children's mothers), and nonresident biological fathers. Second, it presents a brief discussion of the ways in which fathers contribute to childrearing. Third, it describes the socioeconomic characteristics of men who enter fatherhood at a young age, highlighting that they tend to be socioeconomically disadvantaged. Fourth, it reviews the empirical research on both antecedents of father involvement and patterns of involvement across father types. Finally, it describes the limitations of existing research and provides suggestions for future research and policy. 相似文献

How effective was organizational reform implemented inside one critical New York City health agency? Specifically, we examine the extent to which the reorganization of the HIV/AIDS Services Administration (HASA) into the Medical Insurance Services Administration (MICSA) achieved three goals: (1) realizing synergies among the component MICSA programs; (2) cross‐fertilizing ideas among MICSA agencies; and (3) facilitating HASA operations through the lens of organization change theory. Qualitative methods including interviews, site visits, and document analysis triangulate the effects of the reorganization. Implications for organization change literature are explored, especially highlighting where more theoretical and empirical studies are needed. 相似文献

Since 1944, United States financing of the International Monetary Fund (IMF) has been appropriated and approved in Congress by roll-call vote. If voting to increase funds to the IMF is viewed as an observable signal of ??support?? for the IMF, these votes provide a historical record of legislative support for the IMF in the United States. I analyze roll-call voting on IMF financing from 1944 to 2009 at both the aggregate (congressional) and the micro (legislator) levels. At the aggregate level, I show that support for the IMF has fallen over time in the House of Representatives but not in the Senate. In the micro-analysis, I use a ??natural experiment?? to establish that this intercameral difference is the result of the Senate??s larger and more heterogeneous constituencies, as opposed to other modeled and unmodeled factors. I also find that legislator support for the IMF is shaped strongly by ideology: regardless of chamber, left-wing legislators are as much as 31 percentage points more likely to support the IMF than right-wing legislators. Yet controlling for ideology, senators are more likely to support the IMF than representatives, and representatives are more sensitive to constituency pressures than senators. I attribute these differences to chamber-specific rules governing the size of constituencies. 相似文献

Parole officials have traditionally been afforded considerable discretion when making sanctioning decisions to be able to tailor sanctions according to substantively rational concerns such as individuals' unique needs and situations. However, the application of substantive rationality in sanctioning can also generate unwanted disparities because sanctioning decisions may be based on extralegal factors that parole officials consider relevant. Concerns regarding disparate treatment of offender groups have prompted a number of states to consider adopting administrative violation response policies that emphasize formal rationality and uniformity by restricting parole officers' discretion and structuring sanctioning decisions according to legally relevant criteria. By emphasizing formal rationality in sanctioning, structured sanction policies present a dilemma for parole officers—uniformity versus individualized treatment. In 2005, the state of Ohio implemented an administrative violation response policy designed to reduce parole officers' reliance on revocation hearings and promote uniformity in sanctioning decisions. This study involved an examination of whether Ohio's shift to structured sanctioning coincided with differences in legal and extralegal effects on parole officers' decisions to pursue revocation hearings. Analyses of data collected before and after the implementation of the policy revealed a reduction in the number of revocation hearings officers pursued. Only modest increases in uniformity were observed, however, because there was little disparity resulting from officers' hearing decisions before the policy was put in place. These findings are discussed within perspectives on justice system actors' decision making. 相似文献

Although extensive research analyzes the factors that motivate European parties to shift their policy positions, there is little cross‐national research that analyzes how voters respond to parties’ policy shifts. We report pooled, time‐series analyses of election survey data from several European polities, which suggest that voters do not systematically adjust their perceptions of parties’ positions in response to shifts in parties’ policy statements during election campaigns. We also find no evidence that voters adjust their Left‐Right positions or their partisan loyalties in response to shifts in parties’ campaign‐based policy statements. By contrast, we find that voters do respond to their subjective perceptions of the parties’ positions. Our findings have important implications for party policy strategies and for political representation. 相似文献

This study has shown that the combination of simple techniques with the use of multivariate statistics offers the potential for the comparative analysis of soil samples. Five samples were obtained from each of twelve state parks across New Jersey in both the summer and fall seasons. Each sample was examined using particle‐size distribution, pH analysis in both water and 1 M CaCl2, and a loss on ignition technique. Data from each of the techniques were combined, and principal component analysis (PCA) and canonical discriminant analysis (CDA) were used for multivariate data transformation. Samples from different locations could be visually differentiated from one another using these multivariate plots. Hold‐one‐out cross‐validation analysis showed error rates as low as 3.33%. Ten blind study samples were analyzed resulting in no misclassifications using Mahalanobis distance calculations and visual examinations of multivariate plots. Seasonal variation was minimal between corresponding samples, suggesting potential success in forensic applications. 相似文献

An existing victim and witness advocate program is described and evaluated in terms of costs, benefits, and operations. Quantitative and qualitative data indicate that the program is cost beneficial and is also socially beneficial to both the victims and witnesses and the criminal justice system. Proposed programmatic changes are recommended to further improve the programs. 相似文献
