Cognitive Self‐Regulation and Depression: Examining Academic Self‐Efficacy and Goal Characteristics in Youth of a Northern Plains Tribe

The relationship between cognitive self‐regulatory processes and depression was examined in American Indian adolescents from a Northern Plains tribe. Students completed measures of negative life events, self‐efficacy, goals, and depressive symptoms. Results indicated that academic self‐efficacy was strongly associated with depression. Academic self‐efficacy also correlated with intrinsically motivating goal representations, such that students who indicated high academic self‐efficacy had goals that were more important to them, goals they thought more about, and goals they viewed as wanted by the self instead of as imposed on by others. However, we did not find the hypothesized mediational model in which academic self‐efficacy influenced depression indirectly by influencing goal characteristics. Rather, this indirect model varied by grade, and differed from what we expected. Specifically, for older adolescents, higher levels of academic self‐efficacy predicted goals that were more likely to be identified as the adolescent's own, and in turn, these self‐ as opposed to other‐oriented goals predicted higher levels of depressive symptoms. Results are discussed as providing support for continued investigations into the role of specific cognitive self‐regulatory processes in youth adjustment.     

Geographic Mobility and Spatial Assimilation among U. S. Latino Immigrants1

Although the spatial assimilation of immigrants to the United States has important implications for social theory and social policy, few studies have explored the atterns and determinants of interneighborhood geographic mobility that lead to immigrants’residential proximity to the white, non‐Hispanic majority. We explore this issue by merging data from three different sources ‐ the Latino National Political Survey, the Panel Study of Income Dynamics, and tract‐level census data ‐ to begin unraveling causal relationships among indicators of socioeconomic, social, cultural, segmented, and spatial assimilation. Our longitudinal analysis of 700 Mexican, Puerto Rican, and Cuban immigrants followed from 1990 to 1995 finds broad support for hypotheses derived from the classical account of minority assimilation. High income, English language use, and embeddedness in Anglo social contexts increase Latino immigrants’geographic mobility into Anglo neighborhoods. U. S. citizenship and years spent in the United Stares are ppsidvely associated with geographic mobility into more Anglo neighbor oods, and coethnic contact is inversely associated with this form of mobility, but these associations operate largely through other redictors. Prior experiences of ethnic discrimination increase and residence in public housing decreases the likelihood that Latino immigrants will move from their origin neighborhoods, while residing in metropolitan areas with large Latino populations leads to geographic moves into “less Anglo” census tracts.     

Evaluation of the Physical Hazards Associated with Two Remedial Alternatives at a Superfund Site

This study presents an evaluation of the risks due to the physical hazards associated with two remedial alternatives for a former chemical manufacturing facility in New Jersey. Both the on-site and off-site risk of work-related fatalities during remedy implementation and the risks of accident or accident-related fatalities during the off-site transport of site-related materials were evaluated. The two remedial alternatives evaluated were on-site containment and excavation with off-site incineration. The risk of at least one fatality due to a work-related accident was estimated for on-site activities associated with each remedial alternative, and for off-site incineration. The risks of at least one accident and of one accident-related fatality were calculated with accident and fatality data from the U.S. Department of Transportation. In addition, the risk of at least one accident that might potentially affect a natural resource (e.g., river, lake, or national park) was evaluated. This evaluation indicates that the risk of a work-related fatality is over an order of magnitude higher, and the risk of an accident or accident-related fatality is over three orders of magnitude higher, for the excavation/off-site incineration remedial alternative than for the on-site containment alternative. Overall, this study indicates that the physical hazards associated with excavation and off-site incineration are much greater than those associated with on-site containment for this site. Therefore, if a choice between the two remedial alternatives were to be made based solely on physical hazards and accident risk, the on-site containment alternative would be more protective of human health and the environment than the excavation/off-site incineration alternative.     

REGULATORY UPDATES: ICH E14 draft consensus guideline on clinical evaluation of QT/QTc interval prolongation

ICH E14 calls for public comment by epidemiologists and statisticians on the practical implications of thresholds to be used for regulatory decision‐making. Readers involved in QT/QTc assessment in drug development and those with an interest in this area are encouraged to give the topic some thought and to be prepared to engage in public debate on the proposed ICH E14 guidance in late 2004 and early 2005.

Parental experiences in cases of child sexual abuse: a qualitative study

This paper describes the themes which emerged from in-depth interviews with parents of a small number of Australian children who were believed to have been sexually abused. The parents' experiences in the wake of the abuse, including their involvement with three services - a hospital counselling service, the statutory child protection service, and the police - were explored in home interviews conducted 3 months following termination of the case by these services. The themes include: issues related to trust and authority in the casework relationship; expectations of counselling; contamination of normal sexuality in the family; the perception of the sexually abused child as'damaged'; and relationships within their family and social network. Some of the implications for practice are discussed.     

Assessing the Effects of Urbanism and Regionalism on Gender‐Role Attitudes, 1974–1998*

In this article, we analyze the effects of urbanism and Southern regionalism on traditional gender‐role attitudes. Our main dependent variable is an index of gender traditionalism constructed from four items asked across several years from 1974 to 1998 by the General Social Survey. As in previous research and consistent with the classical theoretical propositions of Wirth and Stouffer, we find that people living in more urban areas are more likely to hold more contemporary gender‐role attitudes compared to those living in less urban areas, and that those living in the South tend to maintain more traditional attitudes than their non‐Southern counterparts. The propositions of Wirth also predict a convergence in attitudes over time, creating similar attitudes across residential locations. Our findings support this assertion.     

A New Approach to Estimating Life Tables with Covariates and Constructing Interval Estimates of Life Table Quantities

Extant approaches to constructing life tables generally rely on the use of population data, and differences between groups defined by discrete characteristics are examined by disaggregating the data before estimation. When sample data are used, few researchers have attempted to include covariates directly in the process of estimation, and fewer still have attempted to construct interval estimates for state expectancies when covariates are used. In this paper, we present a Bayesian approach that is useful for producing interval estimates for single‐decrement, multiple‐decrement, and multistate life tables. The method involves (1) estimating a hazard or survival model using Bayesian Markov chain Monte Carlo (MCMC) methods to produce a sample from the posterior distribution for the parameters of the model; (2) generating distributions of transition probabilities for selected values of covariates using the sample of model parameters; (3) using these distributions of transition probabilities as inputs for life table construction; and (4) summarizing the distribution of life table quantities. We illustrate the method on data simulated from the Berkeley Mortality Database, data from the National Health and Nutrition Examination Survey (and follow‐ups), and data from the National Long Term Care Survey, and we show how the results can be used for hypothesis testing.
