Student Functioning,Concerns, and Socio-Personal Well-Being

The following study used the Student Quality of Lifeand Satisfaction (SQOLAS) instrument and 467University of Rhode Island undergraduate and graduatestudents as participants in order to examinerelationships among functioning and performancevariables, student concern and importance areas, andmeasures of socio-personal satisfaction andwell-being. Canonical correlational analysis revealedtwo statistically significant canonical correlationsbetween a student functioning/performance variable setand a concern/importance area variable set. A set ofvariables related to increased concern and importanceratings of socio-sexual behavior, and decreasedratings of crime, violence, multicultural, and genderissues was significantly associated with a second setof variables: increased levels of alcohol use andassociated negative consequences, younger age,increased mental health concerns, men more than women,decreased class year, and less positive ratings towarddirection in life. Standard multiple regressionanalysis produced a statistically significant modelwhere positive attitude towards direction in life canbe predicted by higher levels of socio-personalsatisfaction and deep metacognitive processing, andlower levels of alcohol use and associated negativeconsequences, and fewer mental health concerns.Implications of the results are discussed in relationto theories of cognitive behavior, phenomenologicalfunctioning, life meaning, and well-being.     

Imaging convex quadrilateral inclusions in uniform conductors from electrical boundary measurements

We demonstrate simulation-based Bayesian imaging from electrical impedance tomographic data, by summarizing the set of conductance images which could give rise to the data. The forward map from conductance image to data requires the solution of a partial differential equation subject to boundary conditions. We develop the example of recovering an unknown convex polygonal insulating inclusion within an object made of otherwise uniformly conducting material, and illustrate our methods with noisy synthetic data. Sampling is carried out using Markov chain Monte Carlo with the efficiency of the algorithm investigated over a range of noise levels.     

The magnitude of educational disadvantage of indigenous minority groups in Australia

Indigenous groups are amongst the most disadvantaged minority groups in the developed world. This paper examines the educational disadvantage of indigenous Australians by assessing academic performance at a relatively early age. We find that, by the age of 10, indigenous Australians are substantially behind non-indigenous Australians in academic achievement. Their relative performance deteriorates further over the next 2 years. School and locality do not appear to be important determinants of the indigenous to non-indigenous achievement gap. However, geographic remoteness, indigenous ethnicity and language use at home have a marked influence on educational achievement. A current focus of Australian indigenous policy is to increase school resources. Our results suggest that this will not eliminate indigenous educational disadvantage on its own.

Population Redistribution in Australia: The Problem of Competing Location Preferences

Results from an exploratory survey are used to indicate the importance of the subjective dimension in relocation decisions and policies directed towards population redistribution. The competition between alternative residential location preferences amongst the sample surveyed indicates possible obstacles to the implementation of selective decentralization programmes and the rapid development of designated growth centres.     

Evaluating the complex interactions between malaria and cholera prevalence,neglected tropical disease comorbidities,and community perception of health risks of climate change

The burgeoning literature on the climate change–human health nexus has focused almost exclusively on the health impacts of climate change with little attention to how ill-health and disease influence public perception of the health risks of climate change. Based on a cross-sectional survey of 1,253 individuals, linear regression was used to examine the independent effects of malaria and cholera prevalence, and neglected tropical disease comorbidities on perceived health risks of climate change. Individuals who reported more comorbidities had higher scores on perceived health risks of climate change compared with those who did not report any comorbidities. Unexpectedly, at the multivariate level, there were no statistically significant relationships between age of respondents, gender, and educational attainment on the one hand, and perceived health risks of climate change on the other hand. Individuals who were diagnosed with cholera in the past 12 months had higher scores on perceived health risks of climate change but there was no relationship between diagnosis with malaria in the past 12 months and perceived health risks. Individuals who had attained secondary education had lower scores on perceived health risks of climate change compared with those without any formal education. Given that this relationship did not exist at the bivariate level, it indicates that biosocial and sociocultural factors suppressed the relationship between secondary education attainment and perceived health risks of climate change. The findings underscore the complex relationship between perceived health risks of climate change and infectious disease, comorbidities, compositional, and contextual factors at the multivariate level.     

Measurement and structural invariance of the US version of the Birth Satisfaction Scale-Revised (BSS-R) in a large sample

Background

The 10-item Birth Satisfaction Scale-Revised (BSS-R) is being increasingly used internationally. The use of the measure and the concept has gathered traction in the United States following the development of a US version of the tool. A limitation of previous studies of the measurement characteristics of the BSS-R is modest sample size. Unplanned pregnancy is recognised as being associated with a range of negative birth outcomes, but the relationship to birth satisfaction has received little attention, despite the importance of birth satisfaction to a range of postnatal outcomes.

Robust adaptive Lasso for variable selection

The adaptive least absolute shrinkage and selection operator (Lasso) and least absolute deviation (LAD)-Lasso are two attractive shrinkage methods for simultaneous variable selection and regression parameter estimation. While the adaptive Lasso is efficient for small magnitude errors, LAD-Lasso is robust against heavy-tailed errors and severe outliers. In this article, we consider a data-driven convex combination of these two modern procedures to produce a robust adaptive Lasso, which not only enjoys the oracle properties, but synthesizes the advantages of the adaptive Lasso and LAD-Lasso. It fully adapts to different error structures including the infinite variance case and automatically chooses the optimal weight to achieve both robustness and high efficiency. Extensive simulation studies demonstrate a good finite sample performance of the robust adaptive Lasso. Two data sets are analyzed to illustrate the practical use of the procedure.     

Children's behavior problems in the United States and Great Britain

We analyze the effects of family capital on child behavior problems in the United States and Great Britain by comparing a longitudinal survey sample of 5- to 13-year-old children from the 1994 National Longitudinal Survey of Youth (N = 3,864) with a similar sample of children from the 1991 National Child Development Study "British Child" (N = 1,430). Findings suggest that in both societies, male children, those with health problems, and those whose mothers are divorced are at increased risk for behavior problems, while those with stronger home environments are at reduced risk. Family structure effects are more pervasive in Great Britain than in the United States, although some of these findings are a function of our racially diverse U.S. sample. We conclude that parents are important in both societies in promoting child social adjustment, and evidence that the more developed welfare state in Great Britain may substitute for capital at home is weak.
