Childrearing,Self‐Control,and Crime: Additional Evidence*

Gottfredson and Hirschi's model of caregiving to produce high self‐control is examined using survey data from a city population of adults. The data permit assessment of the predictive ability of all three elements of the regimen, separately and in com‐bination. While a combination of the elements of the specified model and some of the individual components prove to be statistically significant predictors of self‐control, the coefficients are only modest ones. In addition, the sequential model of crime production set forth by the theorists proves to be questionable. These findings add to an emerging body of research suggesting that self‐control may be dependent on things other than the childhood caregiving regimen identified in self‐control theory.     

Models, assumptions and model checking in ecological regressions

Ecological regression is based on assumptions that are untestable from aggregate data. However, these assumptions seem more questionable in some applications than in others. There has been some research on implicit models of individual data underlying aggregate ecological regression modelling. We discuss ways in which these implicit models can be checked from aggregate data. We also explore the differences in applications of ecological regressions in two examples: estimating the effect of radon on lung cancer in the United States and estimating voting patterns for different ethnic groups in New York City.     

Evaluating the effect of education on earnings: models, methods and results from the National Child Development Survey

Summary.  Regression, matching, control function and instrumental variables methods for recovering the effect of education on individual earnings are reviewed for single treatments and sequential multiple treatments with and without heterogeneous returns. The sensitivity of the estimates once applied to a common data set is then explored. We show the importance of correcting for detailed test score and family background differences and of allowing for (observable) heterogeneity in returns. We find an average return of 27% for those completing higher education versus anything less. Compared with stopping at 16 years of age without qualifications, we find an average return to O-levels of 18%, to A-levels of 24% and to higher education of 48%.     

Qualitative Health Research with Children

The authors of this article identify and discuss some of the practical and ethical issues of qualitative research with children. The problems are illustrated through a research study about children's experience of asthma, and the way in which they perceive and interpret their condition. It is shown that social research with children has inherent difficulties relating to access, ethical and developmental issues. Researchers do not only have to gain parental permission but also want the child to enter the research voluntarily. Because of the children's stage of development and the asymmetrical relationship between researcher and informants, adequate safeguards and awareness of these problems are essential.     

“Time Immemorial” and Indigenous Rights: A Genealogy and Three Case Studies (Calder,Van der Peet,Tsilhqot'in) from British Columbia

“Time immemorial” has operated as a legal fiction in the discourse of colonization, performing a genealogical function in the construction of “antiquity” and “legal memory” in English law, and repurposed in Indigenous rights cases in Canada. Beginning with a genealogical outline, this paper analyzes “time immemorial” in relation to Settler and Indigenous discourses of time, memory and the land in Calder, Van der Peet, and Tsilhqot'in.
