An evaluation of bridging methods using race data from Census 2000

The question on race from Census 2000 was different from previous censuses because it allowed respondents to select one or more races to indicate their racial identities. Because of this change, the race data from Census 2000 are not directly comparable with data from earlier censuses. Researchers can use `bridging' methods to assign more than one race respondents to single race categories to maximize the comparability of Census 2000 race data with earlier censuses. This paper uses several bridging methods to generate race population estimates and analyzes the variability in those estimates across six single race groups.     

Paternal child care and children's development

This paper uses the NLSY-Child data to assess the effects on cognitive and social-emotional development of father care as a child care arrangement among children in two-parent families with working mothers. Our results show that father care for infants is no better or worse than other types of arrangements. However, toddlers in non-paternal modes of child care (e.g., relatives, family day care or center care) have slightly better cognitive outcomes than those whose fathers provided care. Although our analyses do not provide a definitive explanation for this finding, there is a substantial influx of fathers in our data who provide child care in years 2 and 3 and these fathers appear compositionally different from fathers who provided care during a child's infancy. In particular, there is some indication that these fathers who are newly providing care during a child's toddler years may be temporary care providers due to changing economic circumstances. The research was supported by NICHD grant #HD30944. Responsible editor: Deborah Cobb-Clark.     

Private and Public Displays of Affection Among Interracial and Intra‐Racial Adolescent Couples*

Objective. This article examines variation in displays of affection between interracial and intra‐racial adolescent couples. Method. Using the National Longitudinal Study of Adolescent Health (Add Health), a nationally representative sample of adolescents in the United States, we estimate hierarchical linear models to compare characteristics of interracial and intra‐racial relationships among white, African‐American, Hispanic, Asian American, and Native American adolescents. In our comparisons we highlight three dimensions of relationship attributes: public display, private display, and intimate physical contact. Results. Our findings suggest that interracial couples are less likely than intra‐racial couples to exhibit public and private displays of affection, but are not different from intra‐racial couples in intimate displays of affection. Conclusions. Social barriers against interracial dating still exist such that even though interracial couples are similar to intra‐racial couples in their levels of intimacy in private, they are less comfortable displaying their feelings in public.     

Presidential Success in the Realm of Foreign Affairs: Institutional Reform and the Role of House Committees*

Objective This analysis focuses on institutional reform and the House foreign policy committees to assess the resurgent‐Congress explanation of presidential success in international affairs between 1953–1998. Method Logit models are used to determine the changing effects on presidential success resulting from the support of chairmen and the president's co‐partisans on the foreign policy committees due to the 1970s congressional reforms. Results The analysis illustrates differences in the effects of committee leaders and committee co‐partisans on roll‐call success before and after the reforms. Also, contrasts are found in the effects of the foreign policy panels that differentially influence presidential success. Conclusion The article offers evidence that the institutional reforms that changed the House policy process from one dominated by committee chairs to one responsive to political parties significantly altered presidential success. These findings emphasize the importance of the changing congressional environment in explaining presidential success in foreign policy.     

Assessing the educational literature in the responsible conduct of research for core content

To determine core content for RCR instruction, content analysis was conducted using key instructional resources for ORI's nine RCR "core instructional areas". Topics discussed in these key RCR resources were identified and their frequency across resources was tabulated. Topics covered most frequently were judged to be core content. Although key educational resources cited a variety of references, specific topics and issues addressed were generally consistent across the materials examined. Nonetheless, key resources varied in organization and depth of coverage for core instructional areas. Recent resources were more systematic and comprehensive than earlier works. This was particularly evident in materials about human participant research, conflicts of interest, and data management and sharing. Key resources presented additional "non-core" issues, such as scientific values, ethical principles, creativity and objectivity, moral reasoning, genetics, epidemiological issues, and scientists' societal roles, suggesting that ORI's core instructional areas should be reconfigured or expanded. Because educational material available on RCR and professionalism was so comprehensive, we recommend that ORI consider research integrity, not research misconduct, as one core instructional area. We also recommend that compliance with research regulations be restored as a core instructional area to accentuate ethical, financial and legal requirements related to acceptance of federal funding.     

The Relations among Observational, Physiological, and Self-Report Measures of Children's Anger

Our first goal was to examine the relations among observational, physiological, and self‐report measures of children's anger. Our second goal was to investigate whether these relations varied by reactive or proactive aggression. Children (272 second‐grade boys and girls) participated in a procedure in which they lost a game and prize to a confederate who cheated. Skin conductance reactivity, heart rate reactivity, self‐reports of anger, angry facial expressions, and angry nonverbal behaviors were measured for each turn of the game. We used multi‐level regressions to calculate the relations among the 10 pairs of the five anger variables over the course of the game. Six of the 10 pairs of anger variables were positively related. These findings suggest that measuring children's anger using any one approach may not capture the full complexity of children's overall experience and expression of anger. Furthermore, three of the 10 relations were stronger at higher levels of reactive aggression, although none varied by proactive aggression. These findings suggest that reactive aggression is related to greater cohesiveness in the experience and expression of anger than is proactive aggression.
