The Australian Census Longitudinal Dataset: using record linkage to create a longitudinal sample from a series of cross‐sections

The Australian Bureau of Statistics is creating a longitudinal sample, called the Australian Census Longitudinal Dataset (ACLD), by linking person records across its five‐yearly Census of Population and Housing. This paper proposes a Multi‐Panel framework for selecting and weighting records in the ACLD. This framework can be applied more generally to selecting longitudinal samples from a series of cross‐sectional administrative files. The proposed framework avoids some significant limitations of the popular ‘Top‐Up’ sampling approach to maintaining the cross‐sectional and longitudinal representativeness of a sample over time.     

Protective Factors of Family Life for Immigrant Youth

The purpose of the study was to identify the positive aspects and strengths experienced by newcomer youth within their home environments. Youth between the ages of 15 and 18 years old who immigrated within the previous 2 years and were living in a medium-sized Canadian city were interviewed. Group interviews were conducted with participants at a local community centre. Analysis of the data was completed using concept mapping (Trochim, 1989) which included multidimensional scaling and cluster analysis. Similar to the literature, results indicated that newcomer youth felt secure and experienced positive familial connections. Youth viewed their families as a source of support, while also acknowledging their need for autonomy. Differences between study results and the literature were found in relation to family rules and integration with Canadian culture. Implications of the findings are discussed within a counseling framework for mental health practitioners to better understand the protective resources of resilience available to newcomer youth.     

Project HOPE: Evaluation of Health Science Career Education Programming for Rural Latino and European American Youth

Project HOPE comprises a health science career pipeline program based in social cognitive career theory. The program aims to promote health science career exploration for rural and Latino middle school students while simultaneously emphasizing the importance of achieving in math and science subjects. The authors conducted 2 studies to evaluate Project HOPE using baseline and follow‐up evaluation data. Results of Study 1 indicated that Project HOPE was associated with increases in math/science self‐efficacy for both Latino (n = 42) and European American (n = 31) students. Results of Study 2 indicated that Project HOPE was associated with higher health science career self‐efficacy beliefs for European American students (n = 22) and higher health science career interests for Latino students (n = 28). These results suggest that domain‐specific career interventions for middle school students that focus on jobs tied to the local economy may be a useful way to engage students in career exploration.     

Control charts for generalized exponential distribution percentiles

The generalized exponential (GE) distribution, which was introduced by Mudholkar and Srivastava in 1993 Mudholkar, G. S., Srivastava, D. K. (1993). Exponentiated Weibull family for analyzing bathtub failure data. IEEE Transactions on Reliability 42:299–302. [Google Scholar], has been studied for various applications of lifetime modelings. In this article, five control charts, that comprise the Shewhart-type chart and four parametric bootstrap charts based on maximum likelihood estimation method, the moment estimation method, probability plot method, and least-square error method for the GE percentiles, are investigated. An extensive Monte Carlo simulation study is conducted to compare the performance among all five control charts in terms of average run length. Finally, an example is given for illustration.     

Race-Ethnicity and Health Trajectories: Tests of Three Hypotheses across Multiple Groups and Health Outcomes

Racial-ethnic disparities in static levels of health are well documented. Less is known about racial-ethnic differences in age trajectories of health. The few studies on this topic have examined only single health outcomes and focused on black-white disparities. This study extends prior research by using a life course perspective, panel data from the Health and Retirement Study, and multilevel growth curve models to investigate racial-ethnic differences in the trajectories of serious conditions and functional limitations among blacks, Mexican Americans, and whites. We test three hypotheses on the nature of racial-ethnic disparities in health across the life course (aging-as-leveler, persistent inequality, and cumulative disadvantage). Results controlling for mortality selection reveal that support for the hypotheses varies by health outcome, racial-ethnic group, and life stage. Controlling for childhood socioeconomic status, adult social and economic resources, and health behaviors reduces but does not eliminate racial-ethnic disparities in health trajectories.     

Is Executive Cognitive Function Associated with Youth Gambling?

Our objectives for this report were to identify trajectories of youth gambling behavior, and to examine their relation to executive cognitive function (ECF) and associated problem behaviors. Philadelphia school children, enrolled at ages 10–12 years (n = 387; 49% male), completed three annual assessments of risk behaviors, ECF, impulsivity, problem behaviors and demographics. Across ages 10–15 years, using methods from Nagin et al., two groups were identified: Early Gamblers (n = 111) initiated early and continued in later assessments, and Later Gamblers (n = 276) initiated at later ages and gambled less. Betting money on cards and sports were the most frequently reported gambling behaviors. Using gambling group as outcome, final backward selection logistic regression model showed Early Gamblers are more likely male (P = 0.001), report more active coping (P = 0.042), impulsive behaviors (P ≤ 0.008), and have friends who gamble (P = 0.001). Groups were similar in ECF, parental monitoring, marital status, SES, and race. Early Gamblers had higher incidence of problem behaviors and drug use (all P ≤ 0.006). Two gambling groups were identified in early adolescence with Early Gamblers showing higher levels of impulsivity and comorbid problems but similar levels of ECF compared to Late Gamblers. As more gambling groups are identified through later adolescence, ECF may emerge as a relevant precursor of problem gambling at this later time.     

Low Trait Self-Control in Problem Gamblers: Evidence from Self-Report and Behavioral Measures

Problems with self-control are seen as a key cause of problem gambling behavior. Yet, self-control is rarely studied directly in gambling studies. We demonstrated that self-report and behavioral measures (derived from the strength model of self-control) show lower trait self-control in problem gamblers. In Study 1, a sample of 2,208 undergraduate students from the University of Guelph, Canada (73% female, mean age?=?19?years, SD?=?4) completed a self-report measure of self-control strength. In Study 2, a sample of 296 University of Guelph students and staff (58% female, mean age?=?19?years, SD?=?2) completed multiple behavioral measures of self-control strength. Both studies demonstrated that, compared to lower-risk gamblers, higher-risk gamblers have relative trait self-control deficits.
