Evaluation of some oxygen, sulfur, and selenium substituted ninhydrin analogues, nitrophenylninhydrin and benzo[f]furoninhydrin

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.     

Testing a Model of Resistance to Peer Pressure Among Mexican-Origin Adolescents

This study examined the factors associated with resistance to peer pressure toward antisocial behaviors among a sample of Mexican-origin adolescents (n=564) living in a large Southwestern city in the U.S. A model examining the influence of generational status, emotional autonomy from parents, and self-esteem on resistance to peer pressure was tested independently for boys and girls. Gender differences emerged in the factors that influenced resistance to peer pressure. Results indicated that resistance to peer pressure was influenced by generational status and emotional autonomy from parents for both boys and girls. However, self-esteem was found to influence resistance to peer pressure only for boys.Mayra Y. Bámaca is a graduate student in Family and Human Development at Arizona State University. Her research interests include adolescent development among ethnically diverse populations, the influence of contextual factors in development, parenting adolescents, and resiliency among Latino adolescents and their families. This work was based on the master’s thesis of the first author.Adriana J. Uma?a-Taylor received her Ph.D. from the University of Missouri-Columbia and is currently an Assistant Professor of Family and Human Development at Arizona State University. Her research interests include ethnic identity formation during adolescence and resilience among Latino adolescents and their families.This study was supported, in part, by a grant to the second author from the Fahs Beck Fund for Research and Experimentation of the New York Community Trust.     

Car ownership and welfare‐to‐work

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.     

Interministerielle Netzwerke: Formale und informelle Koordinationsstrukturen bei der Vorbereitung der deutschen Verhandlungspositionen zur Regierungskonferenz 1996

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.     

Agency, Structure and Causality in Political Science: A Comment on Sibeon

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.     

Political Skills or Lying and Manipulation? The Choreography of the Northern Ireland Peace Process

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.
