Parent‐Child Communication About Adolescent Tobacco and Alcohol Use: What Do Parents Say and Does It Affect Youth Behavior?

Parent‐child communication about tobacco and alcohol use is assumed to be critical to child use of these substances, but it rarely has been systematically described and related to adolescent use. This study included a national sample of 537 adolescent‐parent pairs interviewed by telephone at baseline and again 1 year later. Factor analysis of parent reports of communication identified 3 domains: rules and discipline, consequences and circumstances, and media influences. Communication in these domains varied by family characteristics, including parents' substance use and mother's education level. Contrary to assumptions, parent‐child communication was not related to initiation of smoking or drinking. Additional analyses suggested, however, that parent‐child communication about rules and discipline predicted escalation of use.     

Bayesian Estimation of Pharmacokinetic and Pharmacodynamic Parameters in a Mode-of-Action-Based Cancer Risk Assessment for Chloroform

Chloroform is a carcinogen in rodents and its carcinogenicity is secondary to events associated with cytotoxicity and regenerative cell proliferation. In this study, a physiologically based pharmacokinetic/pharmacodynamic (PBPK/PD) model that links the processes of chloroform metabolism, reparable cell damage, cell death, and regenerative cellular proliferation was developed to support a new cancer dose-response assessment for chloroform. Model parameters were estimated using Markov Chain Monte Carlo (MCMC) analysis in a two-step approach: (1) metabolism parameters for male and female mice and rats were estimated against available closed chamber gas uptake data; and (2) PD parameters for each of the four rodent groups were estimated from hepatic and renal labeling index data following inhalation exposures. Subsequently, the resulting rodent PD parameters together with literature values for human age-dependent physiological and metabolism parameters were used to scale up the rodent model to a human model. The human model was used to predict exposure conditions under which chloroform-mediated cytolethality is expected to occur in liver and kidney of adults and children. Using the human model, inhalation Reference Concentrations (RfCs) and oral Reference Doses (RfDs) were derived using an uncertainty factor of 10. Based on liver and kidney dose metrics, the respective RfCs were 0.9 and 0.09 ppm; and the respective RfDs were 0.4 and 3 mg/kg/day.     

Contest time: time, territory, and representation in the postmodern electoral crisis

Prior generations’ electoral crises (e.g., gerrymandering) have dealt mainly with political maneuverings around geographical shifts. We analyze four recent (1998–2003) American electoral crises: the Clinton impeachment controversy, the 2000 Florida presidential election, the Texas legislators’ flight to Oklahoma and New Mexico, and the California gubernatorial recall. We show that in each case temporal manipulation was at least as important as geographical. We highlight emergent electoral practices surrounding the manipulation of time, which we dub “temporal gerrymandering.” We suggest a theory of postmodern electoral crises, in which the rules of time and space are simultaneously in flux. These crises expose concerns with early American democratic theory, which was based on an understanding of “the people” as geographically and temporally unidimensional. Representative systems, therefore, were designed largely without reference to geographic and temporal complexity.     

Capital Constructions: Newspaper Reporting in Death Penalty Cases

This study evaluates aspects of newspaper reporting about death penalty cases and capital defendants. In a content analysis of newspaper coverage of a representative sample of 26 death penalty-eligible defendants who were brought to trial in California, we found that articles tended to cite primarily from law enforcement and prosecutorial sources, focused very heavily on the characteristics of the crime, and omitted or de-emphasized most other aspects of the case. News coverage generally failed to place the criminal behavior of the defendant in any social historical or contextual framework from which readers (as potential voters and jurors) could grasp the potential mitigating elements of the case. We conclude that newspaper coverage of capital crimes may influence public support for the death penalty, and undermine public appreciation of the role of social contextual factors in crime causation in general. It also may bias the perspective with which potential jurors approach specific capital trials and even contribute to the lack of instructional comprehension that has been found to plague the death sentencing process.     

Altruism, ideological entrepreneurs and the non-profit firm

Ideology and altruism are central to understanding the non-profit charitable sector. This paper addresses three questions. Why do people make charitable gifts? Why do they usually give to non-profit organisations? When can non-profits run by committed ideologues compete with profit-oriented entrepreneurs in the provision of services? the altruistic motives of individuals and the ideological commitments of entrepreneurs come together to support charitable organisations. The non-profit form provides a weak guarantee that gifts are not being syphoned off as profits. Furthermore, independent non-profits can often better reflect donors' desires than public agencies constrained by majoritarian claims, and ideological entrepreneurs can use the non-profit form to reify their beliefs without being accountable to profit-seeking investors. A non-profit organisation can only survive, however, if it can attract money and customers. Sometimes its ideological character will facilitate both tasks. Non-ideological customers may, nevertheless, patronise an ideological non-profit if the entrepreneur's commitment helps to guarantee high quality.     

“A Little More Than Kin,and Less Than Kind”: Basic Interests in Vocational Research and Career Counseling

The history of basic interests helps explain their under-use as a meaningful dimension in the interpretation of career inventories. Research and reflection support new attention to basic interests for four reasons: (a) basic interests may be more optimal cognitive categories than other levels of classification, (b) the RIASEC arrangement of general occupational types may not adequately represent the complexity of the interest space, (c) the interest space itself may be differently conceptualized by men and by women, and (d) the realities of work in this technological era are fundamentally different than they were when occupational inventories such as the Strong Interest Inventory? (Campbell, 1977) were designed.     

Best Practice Options: Mali

Mali, a poor country that embraced democracy in 1991, is considered a democratic role model for francophone Africa. It is grappling with several migration issues, including well–established networks that move thousands of Malians abroad, often with false documents, for $2,000 to $3,000; the dependence of the Kayes region, with 1.5 million residents, on emigration, particularly the remittances sent by its workers abroad; and the migration of Mali and Burkina Faso children to work on cocoa and coffee plantations in Côte d'Ivoire and other neighbouring countries.
Mali is generally considered among the poorest five countries around the world, but is also considered one of the most promising democracies in West Africa (Helderman, 2002). The site visit revealed that the Kayes region of Mali is extraordinarily dependent on remittances, which have improved the lives of residents, and added schools and clinics, but do not seem to have led to the establishment of large numbers of businesses that promise stay–at–home development; that the Mali government seems open to co–development, cooperates with assisted return programmes for unauthorized Malians in France, and works with international organizations to attract educated Malians back to Mali; and that Mali is open to donor suggestions for economic development so that most residents will not have to depend agriculture and cattle raising in a water–scarce region. However, there was little evidence that Mali and its donors have found the country's comparative advantage for sustained economic growth.     

Antisocial and Prosocial Teasing Among Children: Perceptions and Individual Differences

Two studies examined fifth‐ and sixth‐grade students’ perceptions of antisocial and prosocial teasing among peers and potential correlates of individual differences in their tendencies to engage in both forms of teasing. The children were rated as showing a greater tendency to be prosocial teasers than antisocial teasers by both teachers and peers. In addition, the children indicated that they generally experienced and observed prosocial teasing more frequently than antisocial teasing at home and in school. Although boys were perceived to tease in a hostile, antisocial manner to a greater extent than were girls, the evidence for a gender difference in affiliative, prosocial teasing among these children was relatively weak. Additionally, systematic relations were found among ratings of the children's tendencies to engage in antisocial and prosocial teasing with peers, teachers’ ratings of their general level of antisocial and prosocial behavior with peers, ratings of the frequency with which they experienced antisocial and prosocial teasing at home and at school, and their attitudes toward antisocial and prosocial teasing.
