Mentoring adolescent foster youth: promoting resilience during developmental transitions

The current exploratory study used quantitative and qualitative data from an evaluation of the ‘Advocates to Successful Transition to Independence’ programme, a mentoring programme designed to train mentors to assist older adolescent foster youth in acquiring skills and resources needed for successful transition out of foster care and into adulthood. The study was conducted in two phases over 2 years. Quantitative methods were used to describe characteristics of the older adolescent foster youth and advocates, and qualitative methods were used to describe the experiences of youth and advocates in the programme. Results suggest that the use of a mentoring programme for older adolescent foster youth represents a particularly beneficial prevention strategy that may help prevent negative outcomes as youth emancipate from the foster care system and transition into young adulthood. Implications and recommendations for developing mentoring programmes for transition‐aged youth are presented.     

Semi‐Parametric Models for the Multivariate Tail Dependence Function – the Asymptotically Dependent Case

Abstract. In general, the risk of joint extreme outcomes in financial markets can be expressed as a function of the tail dependence function of a high‐dimensional vector after standardizing marginals. Hence, it is of importance to model and estimate tail dependence functions. Even for moderate dimension, non‐parametrically estimating a tail dependence function is very inefficient and fitting a parametric model to tail dependence functions is not robust. In this paper, we propose a semi‐parametric model for (asymptotically dependent) tail dependence functions via an elliptical copula. Under this model assumption, we propose a novel estimator for the tail dependence function, which proves favourable compared to the empirical tail dependence function estimator, both theoretically and empirically.     

Characteristics and factors impacting reunification outcomes among Vietnamese immigrant families in the child welfare system

Using a mixed methods approach, this study examined reunification processes and outcomes among Vietnamese immigrant families involved in the child welfare system. A quantitative design was used to describe characteristics and reunification outcomes of Vietnamese immigrant children and families who are involved in family reunification services. Qualitative methods were used to explore factors that may influence reunification outcomes among Vietnamese families.The quantitative portion of the study included an exploratory design using administrative data from one county in the Northern California. The quantitative sample (N = 32) included children entering the foster care system for 8 or more days between January 1, 2001 and December 31, 2007 from child welfare administrative data (CWS/CMS) which was merged with eligibility data (CalWIN) in order to obtain parent and child place of birth to determine country of origin. The qualitative study included an exploratory design using interview data from child welfare workers (N = 8) and Vietnamese immigrant parents who had successfully reunified (N = 7).Quantitative results indicated that the most common type of maltreatment leading to entry into care was caretaker absence or incapacity, an abuse category that is often used in cases of parental substance abuse. 53.8% of Vietnamese immigrant children in the quantitative sample reunified with their parents, which is close to the national rate of reunification. Qualitative findings pointed to the importance of the following factors within reunification: acculturation-related issues, parental substance abuse, child welfare worker cultural competency and issues related to service availability and effectiveness. Implications for social work practice and policy are discussed.     

Scheduling professionals in the retail pharmacy chain

To control operating costs, a zero-one integer programming model is developed to assist pharmacy staff scheduling decisions. Variable scheduling needs are met by the assignment of relief (mobile) pharmacists to help or temporarily replace full-time pharmacists. Assignments of relief pharmacists over a two-week planning horizon are determined with consideration given to variations in wage rates and travel costs together with the underlying corporate, contractual and operating constraints. The developed model has been applied with considerable success using data collected from a business district in the US located in northern Louisiana related to a national retail chain pharmacy. Forecasting the number of chain retail outlets in the near future has been also performed and the results obtained argue in favor of adopting the model by the entire chain.
