Virtual Interpersonal Touch and Digital Chameleons

We studied the characteristics of hand touch with a mechanical device that approximated a handshake, and we then examined the effect of handshake mimicry on assessment of a partner. Two participants interacted with a force-feedback joystick that recorded each of their hand movements individually. The two participants then greeted one another by feeling the recording of the other person’s movements via the force-feedback device. For each dyad, one of the participants actually received his or her own virtual handshake back under the guise that it was the other person’s virtual handshake. Results demonstrated three significant findings. First, for any given participant, a metric that took into account position, angle, speed, and acceleration of the hand movements correlated highly within individuals across two handshakes. Second, across participants, these metrics demonstrated specific differences by gender. Finally, there was an interaction between gender and mimicry, such that male participants liked people who mimicked their handshakes more than female participants did. We discuss the implications of these findings and relate them to theories of social interaction.

Provident funds and investment in developing countries in the Pacific

This report describes the current avenues of investment used by provident fund schemes in seven island nations in the Pacific; the returns on these investments; the criteria for their selection; and the governments' guidelines and restrictions on these schemes. New investment guidelines from 1988 to 1992 are summarized and the reasons for them are explained. Limitations on permitted investment avenues are briefly described. The latter part of the report, and its main focus, analyses the problems faced when trying to balance the interests of provident fund members with national interests when selecting investments. The report concludes with some recommendations for solutions to the problems related to limited investment outlets and government restrictions. To gather information for this report, a questionnaire was sent to the provident fund schemes in the Pacific and the available annual reports were analysed. Responses, when received, have been included.     

Discreteness Causes Bias in Percentage-Based Comparisons: A Case Study From Educational Testing

Discretizing continuous distributions can lead to bias in parameter estimates. We present a case study from educational testing that illustrates dramatic consequences of discreteness when discretizing partitions differ across distributions. The percentage of test takers who score above a certain cutoff score (percent above cutoff, or “PAC”) often describes overall performance on a test. Year-over-year changes in PAC, or ΔPAC, have gained prominence under recent U.S. education policies, with public schools facing sanctions if they fail to meet PAC targets. In this article, we describe how test score distributions act as continuous distributions that are discretized inconsistently over time. We show that this can propagate considerable bias to PAC trends, where positive ΔPACs appear negative, and vice versa, for a substantial number of actual tests. A simple model shows that this bias applies to any comparison of PAC statistics in which values for one distribution are discretized differently from values for the other.     

Conception of male and female homosexual stereotypes among university undergraduates

Following the procedure used by Broverman, Broverman, Clarkson, Rosenkrantz, & Vogel (1970), male and female undergraduates described a male homosexual, lesbian, and normal adult in terms of 41 adjective rating scales, each scale having a masculine and a feminine pole. Results indicated that compared to ratings of the normal adult, the male homosexual was viewed unfavorably and was significantly different from "normality" on 27 scales. Ratings of the lesbian were closer to those for the normal adult, although significant differences appeared on 11 scales. Ratings for the lesbian differed significantly from those for the male homosexual on 20 scales. On all but two scales, lesbian ratings were closer to the more favorable pole than were male homosexual ratings. The position seems supported that male gender nonconformity is viewed more seriously than female gender nonconformity.     

Enabling,structuring and creating elite transnational lifestyles: intermediaries of the super-rich and the elite mobilities industry

ABSTRACT

This article considers how the migration industries lens can be usefully employed in understanding how professional intermediaries enable, structure, and create transnational migration lifestyles of the super-rich. In particular, we examine how intermediaries and their services (1) enable the continued sustenance of transnational migration lifestyles for this group of elites; and (2) structure and create elite transnational lifestyles. This article primarily draws on interviews with professional intermediaries who service the super-rich, and content analysis of their websites and brochures. Inspired by insights from the new mobilities paradigm (and in particular the politics of mobility), we argue for an expanded conceptualisation of the migration industries beyond the literature’s current focus on labour recruitment and migration management. Specifically, we suggest thinking of the migration industries as a collection of actors and services that enable, structure, and create different types of ‘migrants’, their spaces and their highly uneven transnational mobilities – including that of the super-rich and their elite transnational lifestyles. We conclude with suggestions for a research agenda that may help to better understand the role of intermediaries in the creation of differentiated mobilities.     

Single‐Period Two‐Product Assemble‐to‐Order Systems with a Common Component and Uncertain Demand Patterns

We consider a single‐period assemble‐to‐order system that produces two types of end products to satisfy two independent and stochastic customer orders. Each type of product is used to fulfill a particular customer order and these two products share a common component. Furthermore, one customer may confirm her order before the other one, and the manufacturer needs to make a commitment immediately upon the receipt of each customer order on how many products to be delivered. We propose a model for optimizing the inventory and production decisions under the above ATO environment. We also extend our model to the situation where the manufacturer can fulfill the unsatisfied low‐priority demand using the left‐over inventories after fulfilling the high‐priority demand, in case the low‐priority customer arrives first. Numerical experiments are conducted, which provide some interesting insights on the impact of uncertain demand pattern.     

Personality and Life Events as Predictors of Adolescents’ Life Satisfaction: Do Life Events Mediate the Link Between Personality and Life Satisfaction?

This study examined the association among personality traits, life events and life satisfaction, and the underlying pathways from personality traits to life satisfaction. A total of 1,961 adolescents were recruited from 21 secondary schools in Hong Kong. The adolescent version of the Chinese Personality Assessment Inventory (CPAI-A), the Chinese Adolescent Life Events Checklist (CALEC) and the Satisfaction With Life Scale (SWLS) were employed to assess their personality, life events and life satisfaction, respectively. Multiple regression analysis showed there was an additional value of the indigenously derived scales of CPAI-A, including the Family Orientation, Harmony and Ren-Qing scales, in predicting life satisfaction beyond the universal personality traits. Results also indicated that there was a partial mediation effect of negative life events on personality traits in the prediction of life satisfaction.
