Interval Estimation for the Difference of Two Independent Variances

Analytical methods for interval estimation of differences between variances have not been described. A simple analytical method is given for interval estimation of the difference between variances of two independent samples. It is shown, using simulations, that confidence intervals generated with this method have close to nominal coverage even when sample sizes are small and unequal and observations are highly skewed and leptokurtic, provided the difference in variances is not very large. The method is also adapted for testing the hypothesis of no difference between variances. The test is robust but slightly less powerful than Bonett's test with small samples.     

The future of PR is ‘fantastic’, ‘friendly’ and ‘funny’: Occupational stereotypes and symbolic capital in entry-level job advertisements

Over the past decade, there has been a move towards examining public relations as a socio-cultural practice, acknowledging practitioners as influential communicators who produce and symbolise cultural values through public relations messages. Ideally, a diverse group of professionals would aide in representing a diverse society, but to date, the profession remains female dominated. In this article, it is proposed that practitioners’ own discourse do not only establish what is most valued in the occupation and which habitus suits the practice best, but that the discourse also opens and closes occupational entry for new practitioners thereby contributing to a lack of diversity.This article presents the findings of an indicative thematic content analysis of one of the most common, yet under-research sites of discourse, namely entry-level job advertisements in New Zealand and Australia. Using an interdisciplinary approach, the analysis found that the advertisements placed little to no emphasis on the nature of the work, instead focusing on elements of ‘fit’ whereby new entrants were expected to be charismatic, friendly, and willing to work in an environment that is ‘fun’ and ‘flexible’. In doing so, public relations practitioners tacitly created invisible barriers, a self-limiting occupational culture and furthered existing stereotypes of the ‘perfect’ practitioner.     

Extending public relationship-building through the theory of politeness

For more than thirty years, relationship-building has been recognized as central to public relations, and yet, exactly how practitioners go about building and maintaining relationships at the micro level has been insufficiently explored in public relations scholarship. Politeness, or a lack thereof, is ever-present in all communicative interactions, affecting the formation and development of relationships. There is therefore value in extending our understanding of how these relationships are impacted by (im)polite communicative acts. Principally, politeness attempts to balance participants’ face needs or needs for self-esteem through employing various strategies, and this article attempts to explicate the theory of politeness for public relations work. It concludes that an understanding of the fundamentals of politeness theory and strategies enables practitioners to be more effective at building relationships within and across communities, avoiding potential pragmatic failure.     

Problem Gambling Among International and Domestic University Students in Australia: Who is at Risk?

Young people are a high risk group for gambling problems and university (college) students fall into that category. Given the high accessibility of gambling in Australia and its association with entertainment, students from overseas countries, particularly those where gambling is restricted or illegal, may be particularly vulnerable. This study examines problem gambling and its correlates among international and domestic university students using a sample of 836 domestic students (286 males; 546 females); and 764 international students (369 males; 396 females) at three Australian universities. Our findings indicate that although most students gamble infrequently, around 5 % of students are problem gamblers, a proportion higher than that in the general adult population. Popular gambling choices include games known to be associated with risk (cards, horse races, sports betting, casino games, and gaming machines) as well as lotto/scratch tickets. Males are more likely to be problem gamblers than females, and almost 10 % of male international students could be classified as problem gamblers. Hierarchical regression analysis showed that male gender, international student status, financial stress, negative affect and frequency of gambling on sports, horses/dogs, table games, casino gaming machines, internet casino games and bingo all significantly predicted problem gambling. Results from this study could inform gambling-education programs in universities as they indicate which groups are more vulnerable and specify which games pose more risk of problem gambling.     

Exploring the value of involving experts-by-experience in social work research: experiences from Slovenia and the UK

The evidence base for the methodological validity of conducting participatory research is becoming established. This article reviews the experiences of two researchers undertaking Ph.D. studies in Slovenia and UK, respectively, and considers the value of involving service users and carers in social work research. The Slovenian research involved user-researchers who developed research tools and undertook qualitative research. The first author explores the co-researchers’ impact on the research process and its outcomes, identifying both individual and collective empowerment of the co-researchers. The English study involved people from diverse backgrounds, who developed a recovery training programme for carers of people with schizophrenia. The second author describes how the steering group, and the carers who participated in the programme were impacted by the research process and experienced a sense of empowerment and how they influenced the development of new knowledge through the reflexive cycle. The authors draw out the commonalities and differences in our research that add to the existing evidence base supporting the development of participatory inquiry. We conclude by affirming the value of user participation in research in leading to the empowerment of users, the development of new research perspectives, and in contributing to theory in social work research and practice.     

Führungskräfte auf dem Meditationskissen – eine Investition in die Führungskultur bei Bosch

As a result of our fast paced working environment managers are constantly faced with high requirements, which leads to a high stress load. These can impact their professional and individual achievements negatively. The following practice case is illuminating “mindfulness” which plays a highly decisive role in facing these challenges. In the automotive electronics (AE) division at Bosch interventions have been developed, in which “mindfulness” is in the focus. In this case, concrete topics of the interventions are examined, as well as questions about how and why this procedure is useful. The results of the evaluation show, that even when requirements remain high, the perceived stress level of each individual participant is reduced. Moreover we observe an increase in the ability to concentrate and in productivity.     

Muster des schulischen Erfolgs von jugendlichen Migranten in Deutschland: Evidenz für segmentierte Assimilation?

Using the extension of the national PISA 2003 sample (PISA 2003-E) of 15-year-old students, this study analyzes assimilation patterns of immigrants from Turkey, the former USSR, and Poland in terms of educational attainment and performance in mathematics. It explores the extent to which segmented assimilation processes are observed for these groups. Increasing similarity of immigrant students across generations with native students on these dimensions would support the notion of straight-line assimilation, whereas stability in disparities would point to downward assimilation. The results of the study suggest downward assimilation for immigrant students of Turkish descent regarding educational attainment and performance in mathematics. Students whose families immigrated from the former USSR or Poland, in contrast, show patterns of straight-line assimilation. In addition, our analyses suggest that capturing immigrant status as precisely as possible (1.5 generation, intermarriage) is important, as significant differences in educational success and living conditions of these groups would otherwise be overlooked.     

The development of intercultural pedagogy and its influences on primary schools: conclusions and perspectives

The integration debate in Germany is closely connected to the education debate. Both are related to recent societal changes. Discussions at the social and political level in the past couple of years have shown how highly emotionally charged attitudes towards migration and integration in this country truly are. This article aims to provide an overview of intercultural developments in German educational contexts, especially those related to primary schools, against the background of societal change. We trace the developments in Germany from foreigner pedagogy and intercultural pedagogy to a pedagogy incorporating antiracism elements and subsequently a pedagogical approach focused on diversity (diversity pedagogy). We conclude that though many gains have been made, there is presently a danger that we will lose sight of cultural heterogeneity as diversity pedagogy in Germany has expanded to incorporate social inclusion.     

Homo ludens im sozialwissenschaftlichen Seminar

The teaching of social sciences consists of social interactions and is, therefore, an appropriate object for scientific analysis. A game-theoretic approach reveals that ”chicken games“ and ”prisoner’s dilemmas“ are abundant in university level courses. It can also deliver systematic solutions to the problems of cooperation students and teachers are confronted with in everyday a cademic life. One of these solutions is the reforming of courses into games, as based on a perspective borrowed from cultural anthropology. ”Excitement and fun“ become the ”selective incentives“ which may boost seminar interaction and output, and forge ”privileged groups“, i.e. ”teams“.
