Factor Structure,Reliability, and Known Groups Validity of the German Version of the Childhood Trauma Questionnaire (Short-Form) in Swiss Patients and Nonpatients

The Childhood Trauma Questionnaire–Short Form is the most widely used instrument to assess childhood trauma and has been translated into 10 languages. However, research into validity and reliability of these translated versions is scarce. The present study aimed to investigate the factor structure, internal consistency, reliability, and known-groups validity of the German Childhood Trauma Questionnaire–Short Form (Bernstein & Fink, 1998). Six-hundred and sixty-one clinical and nonclinical participants completed the German Childhood Trauma Questionnaire–Short Form. A confirmatory factor analysis was conducted to assess the 5-factor structure of the original Childhood Trauma Questionnaire–Short Form. To investigate known-groups validity, the confirmatory factor analysis latent factor levels between clinical and nonclinical participants were compared. The original 5-factor structure was confirmed, with only the Physical Neglect scale showing rather poor fit. As a conclusion, the results support the validity and reliability of the German Childhood Trauma Questionnaire–Short Form. It is recommended to use the German Childhood Trauma Questionnaire–Short Form to assess experiences of childhood trauma.     

Cross dock scheduling: Classification,literature review and research agenda

At cross docking terminals incoming deliveries of inbound trucks are unloaded, sorted, moved across the dock and finally loaded onto outbound trucks, which immediately leave the terminal towards their next destination in the distribution chain. Accordingly, a cross dock is a consolidation point in a distribution network, where multiple smaller shipments can be merged to full truck loads in order to realize economies in transportation. In this context, the truck scheduling problem, which decides on the succession of truck processing at the dock doors, is especially important to ensure a rapid turnover and on-time deliveries. Due to its high real-world significance, several truck scheduling procedures have been introduced during recent years, which all treat specific cross dock settings. In order to structure and promote scientific progress, this paper introduces a classification of deterministic truck scheduling. With the help of this classification, existing literature is reviewed and future research needs are identified. Moreover, we represent a yet unexplored class of truck scheduling problems which is highly relevant in real-world distribution networks.     

Preparing international social work students to engage with unequal power relations

Global processes with their political, economic, social, and environmental implications have led to growing awareness of the need to train social workers for transnational/international practice. In this article, we propose a model to prepare students for the complexity of international social work practice in an arena characterized by unequal relations between the parties taking part on international social work training. Helms’ White and People of Color Racial Identity Model will serve to conceptualize the process that students go through in relation to themselves, the Other and sociopolitical realities while learning and training in international social work.     

The Bernstein–von Mises theorem in semiparametric competing risks models

Semiparametric Bayesian models are nowadays a popular tool in event history analysis. An important area of research concerns the investigation of frequentist properties of posterior inference. In this paper, we propose novel semiparametric Bayesian models for the analysis of competing risks data and investigate the Bernstein–von Mises theorem for differentiable functionals of model parameters. The model is specified by expressing the cause-specific hazard as the product of the conditional probability of a failure type and the overall hazard rate. We take the conditional probability as a smooth function of time and leave the cumulative overall hazard unspecified. A prior distribution is defined on the joint parameter space, which includes a beta process prior for the cumulative overall hazard. We first develop the large-sample properties of maximum likelihood estimators by giving simple sufficient conditions for them to hold. Then, we show that, under the chosen priors, the posterior distribution for any differentiable functional of interest is asymptotically equivalent to the sampling distribution derived from maximum likelihood estimation. A simulation study is provided to illustrate the coverage properties of credible intervals on cumulative incidence functions.     

Die Definition in der betriebswirtschaftlichen Forschung — Reflexionen und empirischer Befund

Zusammenfassung  Definitionen geh?ren zum Handwerkszeug eines jeden Wissenschaftlers. Durch sie muss — speziell in den Realwissenschaften — den Adressaten wissenschaftlicher Erkenntnis laufend der Rückschluss von der sprachlichen Darstellung auf den behandelten in der Wirklichkeit vorhandenen Gegenstand erm?glicht werden. Dieser Beitrag hat zum Ziel, Funktion und alternative Formen der Definition zu verdeutlichen und zu beurteilen. Eine empirische Untersuchung über den Gebrauch der Definition in der Betriebswirtschaftslehre versucht die Konvention zu erheben, damit eigene Definitionen auf „festen Grund“ gestellt werden k?nnen.

On the use of definitions in business research — thoughts and empirical findings

Summary  Definitions are among the most basic tools of every scientist. Especially in the social sciences, they constitute an essential means for the addressee of the scientific insight, in order to infer from the linguistic term to the actual object in reality. The aim of this article is to explain and assess functions and alternative forms of definitions. By an empirical study on the use of definitions in business science literature, we identify linguistic conventions which assist in laying the foundation for subsequent definitions.

     

The consequences of own and spousal disability on labor market outcomes and subjective well-being: evidence from Germany

In this paper, I contrast the effects of individual and spousal disability on subjective well-being and labor supply using data on couples from the German Socio-Economic Panel for the years 1984–2006. I find almost no effects in terms of labor market outcomes for both men and women, which stands in stark contrast to the effects of individual disability. The life-satisfaction of women, but not of men, is reduced considerably by their partners’ disability. The effects are about 50–73 % as large as those of individual disability. I also find no evidence that individuals adapt to their partners’ disability, although there is adaptation to individual disability.     

How Dresses Can Make You Mentally Ill: Examining Gender Identity Disorder in Children

This paper examines the diagnostic category of Gender Identity Disorder in Children (GIDC) and its evolution. It also critiques the continued use of GIDC on conceptual, psychometric, and ethical grounds. Gender atypicality is a social construction that varies over time according to culture and social class and therefore should not be pathologized.
