The roller-coaster of experiences: becoming the parent of a deaf child

When early testing indicates a hearing loss, parents find themselves on a roller-coaster of experiences leaving little time or space for reflection. This study is based on interviews with families in the Flemish region of Belgium, one of the earliest in the world to introduce universal neonatal screening for hearing loss. Starting from a phenomenological approach, we explore parents’ accounts of their experiences in order to uncover the meanings of early parenting of a child identified with a label. Soon after birth, these parents encounter a different world in which intertwined discourses construct parenthood with a deaf child. During the process of becoming a parent, representations of deafness as impairment were omnipresent. In contrast to a medical and technological perspective that insists on the need to intervene as fast as possible, it is argued that the private and social implications of rapid intervention require explicit consideration.     

t-Type corrected-loss estimation for error-in-variable model

In this article, we consider a linear model in which the covariates are measured with errors. We propose a t-type corrected-loss estimation of the covariate effect, when the measurement error follows the Laplace distribution. The proposed estimator is asymptotically normal. In practical studies, some outliers that diminish the robustness of the estimation occur. Simulation studies show that the estimators are resistant to vertical outliers and an application of 6-minute walk test is presented to show that the proposed method performs well.

What Works in Group Care? - A Structured Review of Treatment Models for Group Homes and Residential Care

This paper presents findings from a structured review of treatment models that are relevant to group care and residential treatment settings for children involved with the child welfare system. Initiated and guided by The California Evidence-Based Clearinghouse for Child Welfare, five treatment models — Positive Peer Culture, Teaching Family Model, Sanctuary Model, Stop-Gap Model, and Re-ED — were reviewed for effectiveness. In this paper, each model's treatment features are described and relevant outcome studies reviewed in terms of their effectiveness as well as relevance for child welfare practice. Findings indicate that four of the models are either supported or promising in terms of evidence for effectiveness. Implications for group care practice and research are discussed.     

Mixed contracts for the newsvendor problem with real options and discrete demand

In this paper we consider the newsvendor model with real options under discrete demand. We consider a mixed contract where the retailer can order a combination of q units subject to the conditions in a classical newsvendor contract and Q real options on the same items. We provide a closed form solution to this mixed contract when the demand is discrete and study some of its properties. In particular we demonstrate that a mixed contract may be superior to a real option contract when a manufacturer has a bound on how much variance she is willing to accept.     

Evaluationsstudien zum Mentoring

There is a lack of evaluation of mentoring programs which however, in the practice, gains more and more in importance. Therefore, quantitative and qualitative evaluation studies, concerning the process of mentoring have been made in several different size companies as well as in frame of a comparison of mentoring-models in Austria and Germany.A case study which is connected to an evaluation-interview-study completes the perspective of the “women mentees”. At the end, a short is-analysis will be made which shows to what extent, evaluation of mentoring programs are evaluated by companies.The article concludes with a coaching or training program which enables mentors to establish a collegial support based on a structured advisory methodology.     

“The troublesome other and I”: Parallel stories of separated parents in prolonged conflicts

This qualitative study aims to explore how noncohabiting parenting couples in prolonged conflict construct the other parent and themselves. Ten parents from five parent couples were interviewed. A dyadic analytical design was used, where parent's stories of conflict were analyzed in parallel with their co‐parent. Drawing on positioning theory, self‐identity as parents emerged as implicit counter positions in storylines, which construct the co‐parent as “the troublesome other.” Two typologies of conflicted storylines were prominent in the findings: storylines of violations of trust, positioning the co‐parents in relation to traumatic events in the past and, storylines of who is bad, positioning the co‐parent as either a disloyal co‐parent or a dysfunctional parent. The findings indicate that prolonged conflicts made it impossible to find available positions for cooperation. We argue that family therapists should aid each household toward promoting child and family resilience rather than continued efforts to solve chronic conflicts.     

Shift scheduling for tank trucks

In this paper we deal with shift scheduling of tank trucks for a small oil company. Given are a set of tank trucks with different characteristics and a set of drivers with different skills. The objective is to assign a feasible driver to every shift of the tank trucks such that legal and safety restrictions are satisfied, the total working times of the drivers are within desired intervals, requested vacation of the drivers is respected and the trucks are assigned to more favored drivers. We propose a two-phase solution algorithm which is based on a mixed integer linear programming formulation and an improvement procedure. Computational results are reported showing that the algorithm is able to generate feasible schedules in a small amount of time.
