The overlapping coefficient as a measure of agreement between probability distributions and point estimation of the overlap of two normal densities

The overlapping coefficient is defined as a measure of the agreement between two probability distributions. Its relationship to the dissimilarity index and its propertie are described. An extensive treatment of maximum-likelihood estimation of the overlap between two normal distributions is presented as an example of estimating the overlapping coefficient from sample data.     

Developmental Trends in Self-regulation among Low-income Toddlers

The attainment of self‐regulatory skills during the toddler years is an understudied issue, especially among low‐income children. The present study used growth modeling to examine the change over time and the final status in children's abilities to self‐regulate, in a sample of 2,441 low‐income children aged 14 to 36 months. Positive growth in their self‐regulation occurred between 14 and 36 months, but individual variation was observed in both the growth rates and final status. Children who showed high degrees of negativity at 14, 24 and 36 months grew at slower rates than other children. Boys and children high in negativity had lower scores in self‐regulation at 36 months than girls and children with low negativity, whereas higher quality mother–child interactions at 14 and 24 months were associated with better self‐regulation at 36 months. The results suggest that some children may be at risk for developing problems in regulation because of mother–child interaction patterns and child characteristics such as high negativity.     

Dropping out of post-compulsory education in the UK: an analysis of determinants and outcomes

We analyse the decision to drop out of post-compulsory education over the period 1985–1994 using data from the Youth Cohort Surveys. We show that the dropout rate declined between 1985 and 1994, in spite of the rising participation rate in education, but is still substantial. Dropping out is more or less constant over the period of study, though the risk of dropout does vary with young people’s prior attainment, ethnicity, family background and the state of the labour market. The course of study has a substantial effect on the risk of dropout.

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.

The Effect of Distribution Processes on Replenishment Lead Time and Inventory

We investigate the interrelationship of distribution center picking policies and supply chain inventory performance. In particular, we show how the picking sequence in the upstream supply chain link affects the inventory levels of items being replenished to a downstream link for a common “ship‐when‐full” trailer dispatching policy. Perturbing the picking sequence affects items’ inventory levels asymmetrically which causes the aggregate system inventory to vary. We separate the items in replenishment into those units in transit and those awaiting shipment from the upstream distribution step: we call the latter the residual replenishment. We show that the process governing aggregate residual replenishment is Markov and has a stationary distribution that is discrete uniform. Computing the item‐level residual distribution is intractable and so we develop analytical models from which we derive hypotheses for the effectiveness of stable vs. random picking sequences, how item residual replenishment varies with stable picking sequences, and how the aggregate inventory level changes with picking sequence. These suggest a heuristic sequencing algorithm for minimizing inventory, which performs well in simulation tests over a large testbed of parameter sets.     

Exploring Stigmatization and Stigma Management in Mental Health Court: Assessing Modified Labeling Theory in a New Context

Drawing on Link and colleagues' modified labeling theory, this article examines whether the stigma management strategies defendants anticipate using after mental health court exit are associated with their reported experiences during court. Using survey data from 34 mental health court graduates, we find that respondents generally perceive the mental health court as procedurally just, did not experience stigmatizing shame, and anticipate using the inclusionary coping strategy of education over the exclusionary strategies of secrecy and withdrawal. Moreover, findings reveal that the anticipated use of stigma management strategies is associated with mental health court experiences in that procedural justice is associated with inclusionary coping strategies, while stigmatizing shame is associated with exclusionary coping strategies. We conclude by encouraging researchers to further explore the role of stigmatization and shame in specialty court contexts and to continue investigating these defendant perceptions of these courts' process.     

Sociological Stratification: Change and Continuity in the Distribution of Departmental Prestige, 1965–2007

Previous research has found that there is a good deal of stability in departmental prestige, but has not considered its long-term dynamics. This paper investigates a hypothesis implied by some accounts in the sociology of science and organizational theory: that there will be a permanent component of prestige associated with the department or university. The data are the ratings of graduate departments of sociology between 1965 and 2007 using a measure of prestige constructed from hiring patterns. There is no evidence of a permanent component for individual departments, but there is evidence of a permanent difference between departments in “elite” universities and those in other universities. Despite change in rankings within each group, the difference between the groups remained constant over the period. That is, there appear to be enduring barriers that limit the mobility of individual departments.     

Therapist presence in emotionally focused couple therapy blamer softening events: promoting change through emotional experience

The blamer softening event has been associated with successful treatment outcomes in emotionally focused couple therapy. Previous research has highlighted the critical role of softening events and heightened emotional experience in best sessions of emotionally focused couple therapy (EFT). This study examined the effects of a therapist's emotional presence in predicting heightened levels of client emotional experience in blamer softening events. Findings from a detailed analysis of successful and unsuccessful EFT softening attempts demonstrated that a therapist's emotional presence and corresponding evocative vocal quality were more likely to predict heightened levels of client emotional experience in successful softening attempts. Implications of these findings are reviewed in light of EFT research and practice.     

Practice and Research in Career Counseling and Development—2011

The Career Development Quarterly celebrated its 100th anniversary during the past year and continues to provide high‐quality research and conceptual articles of import to the study of career development and intervention. This article reviews the 2011 career counseling and development literature to highlight advances in theory, assessment, and intervention presented within the following themes: (a) from the past to the future, (b) work and well‐being, (c) diversity and career, (d) career theory and concepts, (e) career assessment, (f) career intervention, (g) career development: life‐span perspectives, and (h) international perspectives.     

Strengthening Social Programs to Promote Economic Stability During Childhood

Economic instability has increased in recent decades and is higher for families with low incomes and Black families. Such instability is thought to be driven primarily by precarious work and unstable family structure. In addition, the social safety net has become less of a stabilizing force for low-income families, in part because benefits are often tied to employment and earnings. Too much change in economic circumstances may disrupt investments in children, parenting practices, and family routines—particularly if the economic changes are unpredictable, undesired, or not part of upward mobility. Given the considerable evidence that economic circumstances affect child health and development, economic stability can and should be an important goal of multiple policy domains. In this report, we describe economic instability, review the pertinent theories for considering how economic instability might matter to children, and describe ideas for policies that could reduce or moderate instability. We include policies that reduce instability in earnings, use public assistance to stabilize income or reduce material hardship, or enhance parents' capacity to deal with or avoid instability.
