Models and estimation for systems with recurrent events and usage processes

This paper considers settings where populations of units may experience recurrent events, termed failures for convenience, and where the units are subject to varying levels of usage. We provide joint models for the recurrent events and usage processes, which facilitate analysis of their relationship as well as prediction of failures. Data on usage are often incomplete and we show how to implement maximum likelihood estimation in such cases. Random effects models with linear usage processes and gamma usage processes are considered in some detail. Data on automobile warranty claims are used to illustrate the proposed models and estimation methodology.     

Resettlement challenges faced by refugee claimant families in Montreal: lack of access to child care

Adult refugee claimants experience several well‐documented post‐migratory challenges. Little is known about the resettlement process for refugee claimant families with children. This study reports on 75 open‐ended, in‐depth interviews with refugee claimant families in Montreal about their resettlement challenges and their proposed solutions to them. These interviews were conducted with 33 dyads and triads of children and parents attending a paediatric hospital. Experiences accessing formal and informal child care in Montreal were addressed. Subsequently, a comparative policy analysis was conducted on residency eligibility criteria for child care subsidization. Twenty‐eight out of 39 parents (73%) report a lack of informal or formal child care and 15 out of 33 families (39%) propose improving access to formal child care services. They describe a lack of informal child care as a result of reduced social networks, and affordability as a barrier to formal child care services. Refugee claimants are not eligible for subsidized child care in Quebec. A comparative policy analysis within Canada and comparable countries reveals that this situation is not unique to Quebec. However, most provinces and European countries offer child care subsidies to refugee claimants. Refugee claimants should qualify for child care subsidies. Social workers and community organizations should consider their clients' child care needs in designing programmes and services.     

Weiterbilden und Weiterkommen? Non-formale berufliche Weiterbildung und Arbeitsmarktmobilität in Deutschland

Politicians and the business leaders regularly stress the importance of (further) education for individual life chances. Still, it is far from clear whether non-formal further training, i.?e. short training courses, which are the most common forms of further education in Germany, lead to career advancement. In this study, we analyze the impact of non-formal further training on labor market mobility using data from the German National Educational Panel Study (NEPS) over the period from 2009 to 2016. Event history models for discrete time intervals show that employer-provided courses reduce mobility and promote career stability, which contradicts hypotheses derived from human capital theory, which is commonly used in the literature. More concretely, employer-provided courses prevent downward mobility (safety net function), but also reduce upward mobility and firm changes. Based on these findings, we suggest that future research should consider transaction costs and the firm context as well as the distinction between employer-provided and non-employer-provided training.     

The levers of influence

Physicians often determine the demand for health care services, as well as control the clinical processes aimed at improving health outcomes at the individual and population level. Given their important role in enhancing health status and improving the health care delivery system, it is critical that physician executives master the tools necessary to positively influence physician behavior. But changing behavior is far more complex than "doing it or not doing it." The Nike slogan "just do it" is motivating, but over-simplified. The roots of human change include: consciousness-raising, emotional arousal, commitment, helping relationships, self-reevaluation, reward, and environmental control. A model to effectively influence behavior is presented and includes setting clear expectations, measuring and monitoring performance, providing feedback, and rewarding and recognizing improvement. If all else fails, try discipline. This five-step approach is based on the science of human behavior and working with physicians in diverse settings, ranging from academic medical centers to small practices.     

Treatment of noncustodial fathers: Gender issues and clinical dilemmas

This article addresses issues involved in the treatment of fathers who do not have custody of their children. It reviews literature on demographic trends and discusses fathers' reactions to loss of child custody. Assessment and treatment guidelines are offered so that clinical practice may become more responsive to the needs of the population. Gender concerns, particularly as they relate to transference and countertransference, are also discussed.     

Negative impact of sexual abuse on adult male gender: Issues and strategies of intervention

Although male sexual abuse has co-existed with female sexual abuse, the professional literature has paid minimal attention to the impact of sexual abuse of male children to their adult adaptation. This paper concentrates on the negative impact of sexual abuse on the adult male's gender identity. Examples of eight male clients' responses to sexual abuse in their adult life and the therapeutic framework utilized to work with them are discussed in the paper.This paper was originally presented at the ICAPP conference, 1993.He teaches advanced clinical practice, Human Behavior and AIDS ELECTIVE. He maintains a private practice specializing in Gay men, persons with HIV virus.
