Managerial Selection Decisions in Multinational Corporations: Teaching International Business Using Problem-Based Learning

Companies face many challenges as they staff managerial positions in overseas operations, including decisions on whether to staff using expatriates, host-country nationals, or third-country nationals. We developed an exercise—designed to help students understand the differences between these three groups of employees—that requires students to develop a set of criteria that would form the basis for choosing the candidate they deem to be the best one. In addition, the exercise can serve as a springboard to discussion of the different training and compensation requirements for each of the three different types of employee. The steps involved in the exercise are presented together with suggestions for debriefing the exercise.     

Body image as a leisure constraint: Examining the experience of aerobic exercise classes for young women

Abstract

Previous research has shown that women, and especially young women, in this culture experience pressure to be thin. Although considerable research has been directed toward the investigation of body image and its relationship to psychological health and self‐image, the impact of body image on leisure behavior has not been adequately addressed, nor has body image received much attention as a potential leisure constraint. The purpose of this study was to investigate ways in which body image might function as a constraint to young women's participation in aerobic exercise classes. The study used both quantitative and qualitative methods, including a survey of 190 women undergraduate students and in‐depth interviews with a sub‐sample of 11 students. The qualitative data are the main focus of this analysis. The data indicated that body image did not seem to prevent participation or constrain levels of participation in aerobics. Nevertheless, body image concerns were shown to constrain the enjoyment of aerobics as a leisure activity, and this reduction of enjoyment was related to the clothing worn for aerobics and to competition over appearance and body weight among participants. The findings also showed that body image functioned as a constraint into participation in that body‐image‐related concerns were a major motivating factor exerting pressure on young women to participate in aerobics. In sum, the study suggested that body image can constrain leisure in some situations, although it is not a constraint in the traditional sense of preventing participation. The implications of these findings for the conceptualization of leisure constraints were discussed. Furthermore, some practical implications for the provision of aerobics classes were provided.     

A comparison of work absence periods and the associated costs for two different modes of exercise therapies for patients with longstanding subacromial pain

Abstract

Background: There are no studies on economic issues concerning rehabilitation exercises for shoulder pain.

Objective: The aim of the study was to investigate sick leave and the associated costs after a medical exercise therapy programme in patients with longstanding subacromial pain/impingement.

Methods: A randomised controlled trial in which 61 patients were randomly assigned either to a high-dosage medical exercise therapy group (HD) (n=31) or to a low dosage exercise therapy group (LD) (n=30). Both groups were given three treatments a week over 3 months. The differences between the groups were number of repetitions, number of sets and time performing global aerobic exercises.

Results: The outcome for the HD group was significantly (p<0.05) better compared to the LD group. The reduction in costs for sick leave for the HD group was 59.1%, whereas for the LD group, the reduction was only 42.3%, which is a significant difference.

Conclusion: In patients with longstanding subacromial pain, HD medical exercise therapy might be an efficient treatment approach.

What determines early exercise of employee stock options in Australia?

Employee stock options (ESOs) are a popular way of remunerating employees. We analyse factors at the firm and option level affecting the employee's decision to exercise ESOs before they mature. Exercises over the period 1998–2004 are analysed and the key factor influencing early exercise is found to be dividends. Exercises frequently occur well before maturity, but in most cases little time value is sacrificed. Our findings have implications for the ‘fair’ valuation of ESOs in companies’ financial statements, as required by the relevant Australian accounting standard, AASB 2.
