This study establishes the relationship between a manager’s Machiavellian personality and unethical behavior. It also tests the cross-level interaction effects of collectivism and power distance on the relationship between a Machiavellian personality and unethical behavior. The multi-level and multi-source data are collected from 22 public sector organizations from which 202 responses from managers about their personalities, power distance, and collectivism, and 626 subordinates’ ratings of the managers’ unethical behavior were received and used. The results show that Machiavellian personality has a positive relationship with unethical behavior. The cross-level interaction effects also show that cultural dimensions such as power distance, and collectivism—significantly and positively moderate the relationship between Machiavellian personality and unethical behavior. Based on the study’s findings, implications for theory and practice are offered.

Variations in health and medication use exist across cultures. Medication use among Chinese-Canadian older persons is complicated by many factors including combined use of Western and traditional Chinese medicines (TCM). There is little research on health, psycho-social and cultural determinants of medication use in the Chinese. A cross-sectional census study of community-based Chinese-Canadian older persons in the Kitchener/Waterloo area was conducted using the Minimum Data Set for Home Care and a supplementary questionnaire for cultural issues. The response rate was 89.1 per cent with 106 participants using face-to-face assessments. Socio-demographic and cultural variables were summarized. The multivariate logistic model for TCM use included pain symptoms and being hospitalized, and a curvilinear association between TCM use and health beliefs. For combined medicine use, living with a child, pain symptoms, hospitalization, and social isolation problems were the main effects. Living with a child, physical health problems and number of diseases were associated with Western medicine use. Health, psycho-social and cultural factors were significant determinants for medication use. Education programs for both Chinese-Canadian older persons and health care providers are necessary to understand the appropriate use of Western and TCM treatments.

Background: Cultural factors may influence cross-national variations in elderly suicide rates.

Methods: A cross-national study examining the relationship between elderly suicide rates and elderly dependency ratios was conducted with the a priori unidirectional hypothesis that lower elderly dependency ratios (ratio of people over the age of 65 years to people under the age of 65 years) may imply a greater number of younger people being potentially available to provide support and respect to the elderly and to hold them in high esteem, and this would lead to a reduction in elderly suicide rates. Data on elderly suicide rates, and the total number of elderly and young people were ascertained from the World Health Organization website.

Results: Significant positive correlations were found between the natural logarithm of suicide rates, in both sexes in two elderly age-bands (65–74 years and 75+ years), and the elderly dependency ratio for males, females and both sexes combined.

Conclusions: The impact of elderly dependency ratios on elderly suicide rates may interact with and be modified and mediated through cultural factors. The contribution of cross-national differences in cultural factors on elderly suicide rates require further study by formally measuring cultural factors with validated instruments.

A sample of 119 pairs of twins, together with their 87 siblings and 100 pairs of parents, were examined with respect to susceptibility to the motion sickness syndrome. Children were found to exhibit resistance to the syndrome below two years of age, and females were more susceptible than males. The incidence appeared to be highest in families with both parents affected. Concordance rates were much higher in MZ (100%) than in DZ pairs (27.6%). Genetic effects are likely, but cultural factors should not be ignored.
