Experimentelle vignettendesigns in faktoriellen surveys

Der faktorielle Survey (Vignettenanalyse) als empirisches Messmodell zur differenzierten Untersuchung komplexer Fragestellungen wurde vor allem in der jüngeren Vergangenheit wieder entdeckt und angewandt. Eine Herausforderung bei der Planung fast aller Vignettendesigns stellt die notwendige Reduktion der Vignettenpopulation dar, da zumeist nicht alle Vignetten jedem einzelnen Respondenten zur Beurteilung vorgelegt werden k?nnen. In diesem Beitrag thematisieren wir die mit den verschiedenen Strategien zur Vignettenselektion und Vignettensetbildung verbundenen Implikationen bezüglich der statistischen Analyse und inhaltlichen Interpretation der Ergebnisse. Dabei zeigen sich die Vorzüge von experimentellen Vignettendesigns, die auf den Techniken der gezielt geplanten Fraktionalisierung und Konfundierung aufbauen. Anhand einer Pilotstudie, bei der unter Einsatz des faktoriellen Surveys normative Meinungen über die Zuerkennung der ?sterreichischen Staatsbürgerschaft an Migranten erhoben wurden, beschreiben wir die praktische Umsetzung eines konfundiert faktoriellen Vignettendesigns und dessen ad?quate statistische Analyse. Empfehlungen für die praktische Umsetzung eines experimentellen Vignettendesigns beschlie?en den Beitrag.     

Division of Labor in German Dual‐Earner Families: Testing Equity Theoretical Hypotheses

On the basis of 52 German dual‐earner couples with at least 1 child younger than 5 years, we tested the effects of an unequal division of labor on relationship satisfaction. We analyzed diary reports of time allocated to productive activities according to the actor‐partner‐interdependence model. Hierarchical linear models showed that rather than individual time allocated to household work, the absolute difference in partners’ contribution to productive activities influenced relationship satisfaction. This reduction in satisfaction disappeared after accounting for perceived social appreciation of individual contributions. Models with gender‐specific slopes showed the effect of input and output to be different for women and men. The findings indicate that a relative equity model best explains the effects of an unequal division of labor.     

Balancing Qualified Staff Requirements with Shortage of Recruits in Child Care – The NSW Experience

In Australia and many other countries, government regulations require that children's services, such as long day care centres and preschools, employ certain numbers of qualified early childhood teachers. This recognises that training and experience of staff are the most significant factors determining the quality of care. At the same time Australia is facing a shortage of qualified early childhood teachers, and governments are grappling with how staff requirements can be met. In this article we examine the New South Wales Government approach, which waives temporarily the requirement to employ qualified teachers if children's services providers can show that they have made all reasonable effort at recruiting the required staff. We consider the impact of the temporary waiver on quality of care, and whether it is necessary to compromise government standards in this way. Our research concludes that most providers committed to good quality care do not resort to using the temporary waiver.     

An assessment of the validity and reliability of the SOGS-RA

The present is a validation study seeking to determine the degree of confidence that can be placed on inferences about problem gambling among adolescents in the Atlantic provinces, based on their South Oaks Gambling Screen-Revised for Adolescents (SOGS-RA) scores. The major source of data was a 1998 survey of 13,549 students in junior and high school of the public school systems of the 4 Atlantic provinces of Canada. The SOGS-RA was found to have adequate stability and internal consistency reliability. Statistically significant gender differences were demonstrated relative to endorsement and construct validity. Regarding the latter, this study shows that the existing cut-point of the SOGS-RA score for problem gambling identifies as problem gamblers, markedly different proportions of male than female daily gamblers. Regarding construct validity in relation to the Atlantic Alcohol and Drug Risk Continua, this study suggests that while statistically highly significant, the association between problem gambling and substance-related problems may be of low clinical significance. Regarding criterion validity, there is an urgent need to perform the types of enquiry that will allow clarification about how adolescent problem gambling is conceptualized, by adults versus adolescents, by males versus females, and from a clinical versus a public or population health perspective.     

Differences in health determinants between international and domestic students at a German university

The authors used a standardized questionnaire to survey 201 international and 193 German students at the University of Bielefeld, Germany, to determine differences in health practices between the 2 groups and to identify targets for health-promoting interventions. Multivariate logistic regression models revealed that long-term female international students (those whose duration of residency in Germany was more than 2 years) had lower levels of physical activity and alcohol consumption than their German counterparts and higher rates of smoking independently associated with international citizenship. Short-term international female students were less likely than German students to receive social support. Among men, long-term international student status was associated with daily smoking and inconsistent seat belt use, whereas short-term student status was associated with a lower rate of seat belt use, a higher level of perceived stress, and a healthier diet, compared with domestic students. Findings from the study could give rise to health-promotion activities for international students at German universities; additional studies at other European universities are necessary before making further recommendations.     

Problem Gambling Among Adolescent Students in the Atlantic Provinces of Canada

The objectives of the present study were to determine the prevalence of problem gambling among adolescent students in the Atlantic provinces of Canada, and to determine the role of age and deception about legal age status as potential risk factors for problem gambling. In 1998, a total of 13,549 students in grades 7, 9, 10 and 12 in the public school systems of the four Atlantic provinces completed a self-reported anonymous questionnaire that included the South Oaks Gambling Screen-Revised for Adolescents. About 8.2% and 6.4% of adolescent students met the broad definition of at-risk and problem gambling, respectively. About 3.8% and 2.2% of adolescent students met the narrow definition of at-risk and problem gambling, respectively. The prevalence of problem gambling did not vary according to age. Using a fake identification or lying about one's age was found to be an independent risk factor for problem gambling. Playing video gambling machines was the gambling activity associated with the single greatest independent risk of using a fake identification or lying about one's age. It was concluded that deception about legal age status may be a facilitating factor permitting adolescents to gamble to the point of experiencing problems.     

Das internationale Führungsparkett – Herausforderungen,Haltegriffe und hilfreiche Schrittfolgen

Managers and executives are increasingly facing the challenge of being successful in an complex international context. This article explains the specific demands international co-operation poses on leading executives. It offers encouragement as well as methods which could be used as ‘helping grips’ when observing and coming to terms with situations in this special working environment, with the objective of offering the involved players a larger spectrum of possible action. The first part describes concrete action fields of international co-operation that managers should pay attention to in their daily international work. The second part of the article dedicates itself to the fields of intercultural competencies that are helpful for leading executives. The concluding part deals with some highly demanding general challenges of international co-operation, which managers sometimes describe as surprising and overwhelming, and which are therefore good and quite helpful to know in advance.
