An Information Theoretic Framework for Exploratory Multivariate Market Segmentation Research*

State-of-the-art market segmentation often involves simultaneous consideration of multiple and overlapping variables. These variables are studied to assess their relationships, select a subset of variables which best represent the subgroups (segments) within a market, and determine the likelihood of membership of a given individual in a particular segment. Such information, obtained in the exploratory phase of a multivariate market segmentation study, leads to the construction of more parsimonious models. These models have less stringent data requirements while facilitating substantive evaluation to aid marketing managers in formulating more effective targeting and positioning strategies within different market segments. This paper utilizes the information-theoretic (IT) approach to address several issues in multivariate market segmentation studies. A marketing data set analyzed previously is employed to examine the suitability and usefulness of the proposed approach [12]. Some useful extensions of the IT framework and its applications are also discussed.     

Game On: Past Year Gambling,Gambling-Related Problems,and Fantasy Sports Gambling Among College Athletes and Non-athletes

College students experience higher rates of gambling-related problems than most other population segments, including the general population. Although Division I (D1) athletes often have more at stake than the average student if and when they gamble (e.g., the potential to lose their athletic eligibility), relatively few studies have assessed the gambling behavior of this population and none have specifically assessed fantasy sports gambling. We conducted a study to examine gambling behavior (past-year gambling, gambling-related problems, and fantasy sport gambling) among a sample (N = 692) of college students at a private religiously affiliated university in the Southwest US. The sample for our study was unique in that approximately 30 % of the participants were D1 athletes. We compared the gambling behavior among three groups based on the athlete status: D1 athletes, club/intramural/recreational (CIR) athletes, and non-athletes (NAs). Compared to females in our sample, males observed higher rates of past year gambling, fantasy sports participation, fantasy sports gambling, and gambling-related problems. Among males, we found that CIR athletes observed the highest rates of past year gambling and fantasy sports participation and D1 athletes observed higher rates than NAs. We did not find differences in fantasy sport gambling and past year gambling-related problems based on athlete status in males or females.     

The United Nations Convention on the Rights of the Child: Its Relevance for Adolescents

The United Nations Convention on the Rights of the Child (CRC, United Nations General Assembly, 1989) is a transformative document which has already improved the lives of millions of young people worldwide. Ratified into law by the majority of the countries of the world, it is the first human rights treaty focusing specifically on the rights of individuals under 18 years of age. The rights described in the treaty, however, are often seen as more important for younger children than for adolescents. This policy statement reviews the germane research on the period of adolescence and affirms that the protections and entitlements in the CRC are as important for adolescents as for younger children. Recommendations for policy and research are included.     

Issues of collaboration,representation, meaning and emotions: utilising participant-led visual diaries to capture the everyday lives of people in mid to later life

In recent years there has been an increasing use of visual methods in ageing research. There are, however, limited reflections and critical explorations of the implications of using visual methods in research with people in mid to later life. This paper examines key methodological complexities when researching the daily lives of people as they grow older and the possibilities and limitations of using participant-generated visual diaries. The paper will draw on our experiences of an empirical study, which included a sample of 62 women and men aged 50 years and over with different daily routines. Participant-led photography was drawn upon as a means to create visual diaries, followed by in-depth, photo-elicitation interviews. The paper will critically reflect on the use of visual methods for researching the daily lives of people in mid to later life, as well as suggesting some wider tensions within visual methods that warrant attention. First, we explore the extent to which photography facilitates a ‘collaborative’ research process; second, complexities around capturing the ‘everydayness’ of daily routines are explored; third, the representation and presentation of ‘self’ by participants within their images and interview narratives is examined; and, finally, we highlight particular emotional considerations in visualising daily life.     

Exploring racism inside and outside the mathematics classroom in two different contexts: Colombia and USA

We give attention to the racial contexts of mathematics education in Colombia and the USA. We discuss the particularities of these contexts but also explore the how in both contexts Blackness and Black people are relegated to the lower rungs of the social order. In offering this comparative analysis, we call for expanded research on race, racism, and mathematics education in global contexts.     

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.     

Buffering income loss due to unemployment: Family and welfare state influences on income after job loss in the United States and western Germany

This article analyzes how the family and the welfare state influence household income trajectories after job loss in the United States and in western Germany. Drawing on panel data from the Panel Study of Income Dynamics (PSID) and the German Socio-Economic Panel (GSOEP), I study the income buffering effects of the family and the welfare state in the short an in the long run after job loss. I demonstrate that household income trajectories after job loss in the two countries are similar for couple households. However, men in the United States rely relatively more on family resources to overcome income loss, whereas German men’s incomes are secured mostly by the welfare state. Women’s unemployment in both countries is mainly buffered by their partners’ higher earnings. Because single households have no access to family support, they face much higher losses in the United States than in Germany. I also show that the more generous German welfare state triggers less private self-help in the form of increased labor force participation on the part of women when their partners lose their jobs. Over time, the family has become more important in buffering incomes after job loss in the United States which smoothed men’s and roughened women’s income trajectories in couple households. In Germany, worsening re-employment chances increased income losses in the long run after job loss.     

Talk changes things: The implications of McCloskey's Bourgeois Dignity for historical inquiry

In The Bourgeois Dignity, Deidre McCloskey asserts that although there were many reasons that have been posited for the rise of the bourgeois class and the tremendous increase in the world's standard of living that occurred during the Industrial Revolution, including the enlightenment and the Protestant ethic, something else was required. For her, that something else was a change in the esteem that was afforded to the bourgeois, to capitalists and to capitalism. The talk changed and a change in the talk was what ultimately changed things. In this article, we briefly explore and defend McCloskey's (2010) claim that a change in talk was at the root of the Industrial Revolution. Further, contrary to much of the literature on the relationship between discourse and social change which tends to focus on discourse as an artifact rather than a driver of change, we argue using examples from outside of economics and economic history that a change in talk not only tends to accompany but often precedes dramatic social transformation.
