Emotional and behavioral correlates of Type A behavior in children and adolescents were examined in 184 fifth-, seventh-, and ninth-grade students, classified as high or low Type A, using self-report, teacher ratings (fifth grade only), and structured interview procedures. Measures included the Hunter-Wolf A-B Rating Scale, Behavioral Symptoms of Stress Inventory, Dimensions of Temperament Survey, Desire for Control Scale, Eysenck Personality Inventory, and the Multiple Affect Adjective Checklist. High Type A children reported significantly more stressed-related behaviors, higher levels of depression, anger, anxiety, and cognitive disorganization, and greater reactivity than Low Type A. No differences were found on measures of temperament (activity level, attention span, adaptibility, and rhythmicity), desire for control, or introversion-extroversion. Females, in general, reported significantly more behavioral stress symptoms. However, no other gender differences were found. Possible reasons for reported differences between Type A children and adults are discussed, along with gender differences in behavioral symptoms. Need for multiple measures of Type A across situation is considered along with need for controlled longitudinal studies of Type A components and the influence of contexts.Received Ph.D. from Stanford.

The social and economic consequences of adolescent motherhood are known, yet the psychological associates are largely unstudied. Clinical studies point to distressing reactions to adolescent pregnancy, and do not reflect changes in social attitudes about teenage parenting. In this study, adolescent mothers (n=62), pregnant teenagers (n=63), and non-pregnant and nonparenting (n=60) adolescents enrolled in public high schools completed measures of socioeconomic status, depression, anxiety, loneliness, self-esteem, and social supports. Findings suggest that adolescent mothers and pregnant teenagers are less distressed by their situation than was once thought. Social supports and socioeconomic status predicted psychological well-being better than parenting status. Expanded school programs for teenage mothers and renewed efforts to enhance young mothers' social and socioeconomic resources are called recommended.Funding was provided by the William T.

A simple technique is presented for the longitudinal sectioning of hair samples without the need for any embedding medium. The technique applies to single hair samples that are placed in a groove of a particular depth and can either be scraped or cut to the desired level. Planar sections are obtained that reveal the internal structure of the sample and are ideal for the application of surface analytical techniques for the study of internal transverse and longitudinal distributions of xenobiotics. 相似文献

Six ninhydrin analogues containing oxygen, sulfur, and selenium substituents at the C-5 position, 5-(4-nitrophenyl)ninhydrin, and benzo[f]furoninhydrin were evaluated as fingerprint development reagents. The analogues all showed good fingerprint color development but were not superior to ninhydrin in this respect. The benzo[f]furoninhydrin complex was strongly luminescent at room temperature following zinc complexation, while the remaining analogues required cooling to -196 degrees C to produce optimum luminescence. The benzo[f]furo, nitrophenyl, and methyl selenide analogues showed the best potential as fingerprint reagents with the benzo[f]furo analogue comparing favorably with DFO. 相似文献

This study examines the role of car ownership in facilitating employment among recipients under the current welfare‐to‐work law. Because of a potential problem with simultaneity, the analysis uses predicted car ownership constructed from two instrumental variables, insurance premiums and population density for car ownership. The data come from a 1999–2000 survey of TANF recipients in the Los Angeles metropolitan area. The empirical results show a significant independent contribution of car ownership on employment. The presence of an predicted ownership is associated with a 9 percentage point increase in the odds of being employed. Moreover, the results indicate that lowering insurance premiums by $100 can increase the odds of employment by 4 percentage points. © 2002 by the Association for Public Policy Analysis and Management. 相似文献

How do German ministries manage the preparation of national negotiation positions for EU intergovernmental conference? After a survey of the debate on organizational deficits of the interministerial coordination in Germany, we are consulting decision- and organization-theoretic approaches in IR. Drawing on organizational economics we concretise and supplement these older frameworks. We conceive the management of a governmental organization as a specific aggregation of heterogeneous preferences and information. Applying social network analysis we take into account formal as well as informal aspects of coordination channels. The objective of this article is to make visible the complex structures and processes that constitute foreign policy making, and to provide a preliminary assessment of its efficiency. 相似文献

Researchers in political science are devoting increasing attention to the ontological commitments of their theories – that is, to what those theories presuppose about the nature of the political world. This article focuses on a recent contribution to this 'ontological turn' in political science ( Sibeon, 1999 ). Tensions are identified in Sibeon's account of the causal interplay between agency and social structure. It is argued that these tensions can be resolved by reflecting explicitly on ontological issues, in particular the causal efficacy of social structure, using a particular approach to the philosophy of the social sciences known as critical realism. The value of such reflection for the explanatory power of political analysis is highlighted. 相似文献

The 'real war' and 'propaganda war' fought over Northern Ireland for thirty years polarised party and public opinion. The key dilemma faced by politicians during the recent peace process has been how to wind down the 'war' and win sufficient party and public support for an accommodation between unionists and nationalists which falls so far short of previous expectations. Scripts telling contrasting stories have been prepared to convince rival republican and unionist audiences to support the peace process. In addition, the pro-Agreement parties have attempted to shift opinion towards accommodation through a range of political skills and choreography. Key competing parties and governments have sometimes co-operated back stage while front stage they have on occasion 'play acted' conflict between each other. The political skills, or lying and manipulation, by which the peace process has been driven forward have been uncovered creating public distrust in the political process. Realists see such political deception as an inevitable part of politics and permissible on the grounds that the ends justify the means. Absolutists attack the 'spin, lying and manipulation' of the peace process as an assault on democracy. A third democratic realist position argues that sometimes moral leadership requires doing wrong to do right but the gap between 'truth' and 'spin' should be narrowed. A more open and honest politics would not only be more accountable and democratic but also effective in advancing the peace process. 相似文献
