African American Single Full-time Fathers: How Are They Doing?

Using a symbolic interactionist approach, interviews of 10 Black single full-time fathers indicate that these fathers perceive parenting to have had positive results for themselves. Specifically, the employment and income of most of the men had remained stable or improved. While their dating lives had suffered the most, they had sustained social activities with friends and families at a high level. Moreover, their assessments of their parent-child relationships and their own life satisfaction was positive.     

Equilibrium Labor Turnover,Firm Growth,and Unemployment

This paper considers equilibrium quit turnover in a frictional labor market with costly hiring by firms, where large firms employ many workers and face both aggregate and firm specific productivity shocks. There is exogenous firm turnover as new (small) startups enter the market over time, while some existing firms fail and exit. Individual firm growth rates are disperse and evolve stochastically. The paper highlights how dynamic monopsony, where firms trade off lower wages against higher (endogenous) employee quit rates, yields excessive job‐to‐job quits. Such quits directly crowd out the reemployment prospects of the unemployed. With finite firm productivity states, stochastic equilibrium is fully tractable and can be computed using standard numerical techniques.

Specifying and facilitating family involvement in services to persons with developmental disabilities

This paper recognizes the important role of family involvement in services to people with developmental disabilities. The paper presents a conceptualization of involvement that was an outcome of a qualitative study of involvement from the perspective of family members themselves. The authors identify a framework of family involvement the composition of which incorporates four system levels (i.e. the individual, program/agency, community, society) and the five role opportunities for family members (i.e. treatment agent, planner, advocate, evaluator, and consultant/educator). Barriers to involvement are then delineated and the authors autline a process for promoting family involvement: 1) contracting for involvement; 2) developing a support system for involvement; and 3) monitoring and evaluating involvement.Presented at the Fourth Annual Conference of The Michigan Chapter, National Association of Social Workers, May 14, 1988.

Extremes of Markov chains with tail switching potential

Summary.  A recent advance in the utility of extreme value techniques has been the characteri- zation of the extremal behaviour of Markov chains. This has enabled the application of extreme value models to series whose temporal dependence is Markovian, subject to a limitation that prevents switching between extremely high and extremely low levels. For many applications this is sufficient, but for others, most notably in the field of finance, it is common to find series in which successive values switch between high and low levels. We term such series Markov chains with tail switching potential, and the scope of this paper is to generalize the previous theory to enable the characterization of the extremal properties of series displaying this type of behaviour. In addition to theoretical developments, a modelling procedure is proposed. A simulation study is made to assess the utility of the model in inferring the extremal dependence structure of autoregressive conditional heteroscedastic processes, which fall within the tail switching Markov family, and generalized autoregressive conditional heteroscedastic processes which do not, being non-Markov in general. Finally, the procedure is applied to model extremal aspects of a financial index extracted from the New York Stock Exchange compendium.     

Provincial Conditional Income Convergence in China, 1953-1997: A Panel Data Approach

This paper examines the tendency towards income convergence among China's main provinces during the two periods: the pre-reform period 1953-1977 and the reform period 1978-1997 using the framework of the Solow growth model. The panel data method accounts for not only province-specific initial technology level but also the heterogeneity of the technological progress rate between the fast-growing coastal and interior provinces. Estimation problems of weak instruments and endogeneity are addressed by the use of a system generalized method of moments (GMM) estimator. The main empirical finding is that there is a system-wide income divergence during the reform period because the coastal provinces do not share a common technology progress rate with the interior provinces.     

A Pilot Use of Letters to Clients before the Initial Session

This paper explores the nature of engagement in the therapy process, and proposes that engagement may be facilitated when both client and therapist are able to develop an appreciation of each other's position within the therapeutic relationship. Some ways that a therapist can assist in this process are explored. An experiment is described in which information letters are sent to clients before the initial therapy session, as a possible way to enhance the engagement process.     

Adverse Childhood Experiences and Healthcare Costs in Adult Life

ABSTRACT

The current study aims to present the prevalence of adverse childhood experiences and examine the healthcare costs associated with primary, allied, and specialist healthcare services. The Australian Longitudinal Study on Women’s Health is a general health survey of four nationally representative age cohorts. The current study uses 20 years of survey and administrative data (1996–2015) from the cohort born 1973–1978. Overall, 41% of women indicated at least one category of childhood adversity. The most commonly reported type of childhood adversity was having a household member with a mental illness (16%), with the most commonly reported ACES category being psychological abuse (17%). Women who had experienced adversity in childhood had higher healthcare costs than women who had not experienced adversity. The healthcare costs associated with experiences of adversity in childhood fully justify a comprehensive policy and practice review.     

Penalized likelihood inference in extreme value analyses

Models for extreme values are usually based on detailed asymptotic argument, for which strong ergodic assumptions such as stationarity, or prescribed perturbations from stationarity, are required. In most applications of extreme value modelling such assumptions are not satisfied, but the type of departure from stationarity is either unknown or complex, making asymptotic calculations unfeasible. This has led to various approaches in which standard extreme value models are used as building blocks for conditional or local behaviour of processes, with more general statistical techniques being used at the modelling stage to handle the non-stationarity. This paper presents another approach in this direction based on penalized likelihood. There are some advantages to this particular approach: the method has a simple interpretation; computations for estimation are relatively straightforward using standard algorithms; and a simple reinterpretation of the model enables broader inferences, such as confidence intervals, to be obtained using MCMC methodology. Methodological details together with applications to both athletics and environmental data are given.     

The Challenge of Disability: Being Solution Focused with Families

There is sometimes a perception in the counselling field that work in the area of disability is qualitatively different from all other work. Counsellors can easily disqualify themselves from thinking they have anything to offer when disability is present. This paper highlights the effects and limitations of the sort of thinking which defines clients according to their membership of a particular clinical population, and challenges counsellors to consider what they have to offer in this area. The paper describes the utilisation of a solution focused framework with families who have a child or adolescent with a disability. Some examples of the use of the ‘miracle’ question are described, with a consideration of dilemmas raised where disabilities are long term and unchanging.
