Outpatient marijuana treatment for adolescents. Economic evaluation of a multisite field experiment

An economic evaluation of five outpatient adolescent treatment approaches (12 total site-by-conditions) was conducted. The economic cost of each of the 12 site-specific treatment conditions was determined by the Drug Abuse Treatment Cost Analysis Program (DATCAP). Economic benefits of treatment were estimated by first monetizing a series of treatment outcomes and then analyzing the magnitude of these monetized outcomes from baseline through the 12-month follow-up. The average economic costs ranged from $90 to $313 per week and from $839 to $3,279 per episode. Relative to the quarter before intake, the average quarterly cost to society for the next 12 months (including treatment costs) significantly declined in 4 of the 12 site-by-treatment conditions, remained unchanged in 6 conditions, and increased in 2 treatment conditions (both in the same site). These results suggest that some types of substance-abuse intervention for adolescents can reduce social costs immediately after treatment.     

The Affection Effect in Insurance Decisions

We use insurance behavior as a context to study affective influences in seemingly purely monetary decisions. We report two related findings. First, people are more willing to purchase insurance for an object at stake, the more affection they have for the object, holding the amount of compensation constant. Second, if the object is damaged, people are also more willing to go through the trouble of claiming a fixed amount of compensation, the more affection they have for the object. These effects are not predicted by standard decision theories. We explain these findings by a consolation hypothesis, according to which, people perceive insurance compensation as a token of consolation, and we discuss its implications for affective influences in other types of decisions.

ON THE ESTIMATION OF REACTION FUNCTIONS FOR SEVERAL ECONOMIC POLICY MAKERS

When two policy authorities are exercising instruments to affect a common macroeconomic variable, this paper emphasizes the need for nonpolicy agents anticipating policy actions to identify a separate reaction function for each fully informed policy maker, based on observed equilibrium instrument settings. Estimation problems on reaction functions arise if the policy authorities have imperfect knowledge about the system they are attempting to control: if intercept errors occur in the system, long run policy may attain global equilibrium, but short run observed policy must be modelled as a disequilibrium process; if slope coefficient errors exist, even long run instrument settings may be biased due to asymptotic biases on coefficient estimation by authorities.     

Variability in PAH-DNA Adduct Measurements in Peripheral Mononuclear Cells: Implications for Quantitative Cancer Risk Assessment

Biomarkers such as DNA adducts have significant potential to improve quantitative risk assessment by characterizing individual differences in metabolism of genotoxins and DNA repair and accounting for some of the factors that could affect interindividual variation in cancer risk. Inherent uncertainty in laboratory measurements and within-person variability of DNA adduct levels over time are putatively unrelated to cancer risk and should be subtracted from observed variation to better estimate interindividual variability of response to carcinogen exposure. A total of 41 volunteers, both smokers and nonsmokers, were asked to provide a peripheral blood sample every 3 weeks for several months in order to specifically assess intraindividual variability of polycyclic aromatic hydrocarbon (PAH)-DNA adduct levels. The intraindividual variance in PAH-DNA adduct levels, together with measurement uncertainty (laboratory variability and unaccounted for differences in exposure), constituted roughly 30% of the overall variance. An estimated 70% of the total variance was contributed by interindividual variability and is probably representative of the true biologic variability of response to carcinogenic exposure in lymphocytes. The estimated interindividual variability in DNA damage after subtracting intraindividual variability and measurement uncertainty was 24-fold. Inter-individual variance was higher (52-fold) in persons who constitutively lack the Glutathione S-Transferase M1 (GSTM1) gene which is important in the detoxification pathway of PAH. Risk assessment models that do not consider the variability of susceptibility to DNA damage following carcinogen exposure may underestimate risks to the general population, especially for those people who are most vulnerable.     

THE INFORMATION SOCIETY AS MEGA-MACHINE

Too often the history of information and communication technologies (ICTs) is wrenched out of the history of technology and presented as something altogether separate and therefore different, rendering previous analyses irrelevant. However, there are sufficient analytical tools to hand without the continual invention of new paradigms to understand the current stage of technological advance. To support this contention, in this article, the continuing relevance of Lewis Mumford is explored. Mumford's discussion of the megalopolis and the emergence of the invisible city as its most developed state make a direct link with the networked information society, establishing a link between the information society and Mumford'sanalysis of the previous history of technology.At the centre of Mumford'sdiscussion of this history is the dialectic interaction of authoritarian and democratic technics. Mumford's notion of technics stresses that technologies can not be divided from the social relations in which they appear. In the information society,this dialectical pair map onto the twin dynamics of enclosure and disclosure. The former dynamic represents the control of information through commodification and marketization, the latter the recognition of the empowering and emancipatory qualities of ICTs. Up until now,discussions of the information society have regarded only one or other dynamic as normal, whereas utilizing Mumford'sinsight, the contradictory character of the information society can be theorized without rendering the second dynamic abnormal. Thus, the article concludes that recourse to Mumford's ideas, to re-embed ICTs in the history of technology, allows a more nuanced and fruitful treatment of current developments in information society.     

ASSERTING THE POLITICAL SELF: Community Activism Among Black Women Who Relocate to the Rural South

In this article, I address the collective process of politicization in a group of urban working-class black women who have departed from large cities in the northeast United States and resettled in small towns and scattered, isolated rural communities in the Southeast. The study examines how newcomes became politically involved in their new environment and particularly, how social constraints and opportunities embedded within local political culture influenced their experiences of becoming activists. I employ a critical feminist approach in which an understanding of political agency is grounded in culturally and geographically specific social relations. I argue that activist politics of returnees are framed and formed by unequal gender, race, and class relations resonant in the political culture of the rural South. Localized social conventions define and normalize allowable political roles, discourses, and actions for working-class black women. As newcomers and outsiders, women activists and their actions become politicized in the process of encountering, questioning, and ultimately, subverting these conventions. As the women returnees engaged local political culture, their practices were interpreted as a violation of established paternalist norms of community activism by both white power holders and local working-class black women. This transgression influenced the formation of their identities as political agents and may potentially disrupt the power relations in the surrounding community as well. The study's findings demonstrate the importance of situating race, class, and gender relations in the analysis of activist politics in general and among black working-class women in particular. The study is based on participant observation and interviews with working-class black women activists in three counties in southeastern North Carolina.     

An examination of relationships between children's protective services social worker assessment of risk and independent LONGSCAN measures of risk constructs

Risk assessment as a Child Protective Services (CPS) decision-making model has been implemented in the field since the late 1980s. Research activities on risk assessment have included comparative analyses, prioritization, classification studies, implementation, and cultural sensitivity analyses. In the last decade, the major research focus has been on studies related to predictive validity. Little research on risk assessment has focused on other types of construct validity, including convergent validity. Using data from the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN) and CPS investigation records, this study examined the correlations between CPS workers' ratings of risk on nine risk factors and independent measures of the same risk constructs collected by research interviewers. The data indicate significant correlations with caregiver risk factors such as physical/mental/emotional impairment, however there is little correlation with child risk factors associated with developmental or behavioral issues, or socio-economic factors such as stress and social support. Implications of the findings for policy and practice are discussed.     

Language and power in Japanese transplants in Scotland

Previous research into Japanese owned and managed enterprises in western countries has been alert to problems in cross‐cultural communication but there has been little research into the linguistic patterns accompanying these activities. This study of seven such plants in Scotland illustrates key features of the linguistic patterns evident in them. Forms of pidgin develop in co‐operative working environments but unusually they are based on the language of the formal subordinates, local English speaking managers and workers. In contrast, and more in line with expectations from socio‐linguistic theory, the local dialect is used as a device to promote local workforce solidarity against expatriate management. The former discrepancy between material and cultural power, which is not expected on the basis of Bourdieu's and related theories of cultural behaviour, is explained in terms of the differing career paths of Japanese and non‐Japanese personnel, the marginal involvement of Japanese management in the local society and their reticence in asserting cultural power commensurate with their economic power. However, these lingusitic developments were local phenomena that did not challenge Japanese managerial control, both local and corporate, of decisions on development and investment. Hence, the opposition between cultural and material power may be permitted to persist because of these limited effects.
