Mentoring receipt and personality: Evidence for non-linear relationships

The research investigates the relationship of the Big-Five of personality with mentoring receipt with the use of two independent studies. The findings of the studies show substantial consistency. Equations of quadratic form describe half of the tested relationships better than linear equations. The association of openness to experience and agreeableness with mentoring receipt is of inverted U-shape. The benefits of being open and agreeable for mentoring receipt cease to exist at high values of these traits. On the other hand, emotional stability and conscientiousness demonstrate exclusively positive linear relationships with mentoring receipt. The form of the relationship of extraversion differs between the two studies, but the overall trend is positive. The substantial quadratic component in the association of personality with receipt of mentoring means that research hitherto may be grossly underestimating the effects of personality on developmental relationships because earlier studies assume strictly linear associations. Parts of the results also imply that the associations of certain personality traits with mentoring receipt may depend upon the occupational context.     

Partly primitive: discursive constructions of the domestic surfer

Various studies highlight the importance of discourses in consumer culture, yet fewer explore the historical development of these phenomena. This paper examines a long-view of the meanings and uses of primitive discourse in consumer culture. An investigation of the changing representation of indigenous Hawaiian surfing within Euro-American culture between the late-eighteenth and mid-twentieth century illustrates the ambiguous and malleable articulations of marketplace discourses. We find that over the course of this period, primitive discourses are expressed differently by changing figurations of social actors in manners that serve colonial, celebratory, contemplative and countercultural intentions. Finally, we find that the construction of surfing as a partly primitive marketplace culture combines these discourses to offer consumers a distinct and domesticated theatre of liberatory othering. Illustrating the changing possibilities and potentials for otherness in consumer culture, this paper reaffirms that contemporary marketplace cultures have complex historical roots. These legacies justify extended contextual investigations. Implications concerning representation and the politics of marketplace primitivism are discussed.

The establishment of injury surveillance in Thailand

The Provincial Injury Surveillance System was initiated in Thailand in 1993 to establish a database for assessment of the quality of acute care and referral services provided to the injured at the provincial level, and to facilitate injury prevention and control at both local and national levels. An injury surveillance system model that adopted a trauma registry as the record form, was established in five selected large hospitals, one from Bangkok and four from major regions of Thailand. Data analysis was undertaken and utilized at both local and national levels. The Epidemiology Division of the Ministry of Public Health supervised and assessed the data quality. Evaluators from the School of Public Health identified problems in operating the system at the provincial level and assessed the feasibility of expanding the project. The data of 66,895 injuries including 1,755 deaths reported in 1995; revealed fundamental problems in the emergency medical services. Causes of major injuries were identified and their epidemiology described. The coverage of reporting was over 90%. The completeness and reliability of recording ranged from 80.6–100%. This model of sentinel surveillance is appropriate for injury problems, which are of large magnitude and are at the early phase of problem solving. Development of the information systems administration and human resource in computer technology are necessary to cope with the problems of increased workload in data collecting and processing. This model of surveillance is feasible for expansion but its data system has to be appropriately integrated into the existing systems of the hospitals.     

Values Versus Regulations: How Culture Plays Its Role

This study examines the impact of culture on regulation and corruption. Our empirical results suggest that cultural values have significant effects on countries’ regulatory policies, levels of corruption, and economic development. Contrary to the conclusions drawn by others, this study shows no significant relationship between the regulatory policies of countries and their perceived levels of corruption. Thus, evidence of the “public choice view” toward entry regulation derived in related studies seems to be at least attenuated.

Socio-Cultural Change and Business Ethics in Post-Soviet Countries: The Cases of Belarus and Estonia

The aim of this literature-based study is to explore the influence of socio-cultural factors on business ethics in post-soviet countries with dissimilar cultural contexts. Specifically, this article seeks to identify and compare contextual influences on informal norms of morality in business in transitional post-soviet societies. In order to pursue this investigation, the countries of Belarus and Estonia were identified as being among the most noteworthy examples of culturally different post-soviet countries in transition. The study reveals contradictory manifestations of mixtures of business norms in both Estonia and Belarus, which are conditioned by the merger of an autocratic bureaucratic soviet system with more participative and empowering forms of western management. The most persistent changes relate to moves from patriarchal and paternalistic types of relationship and low work motivation. The significance of these differences, which include nationality and religious legacies, will almost inevitably be overlooked should the countries be placed under the general umbrella of ‘former soviet states’ when considering business ethics in these contexts.

Corporate Philanthropy in the U.K. 1985–2000 Some Empirical Findings

This paper briefly reviews the theories that seek to explain the phenomenon of corporate charitable donations and then provides a review of the empirical issues that have arisen in previous studies in this area. The findings of an analysis of charitable donations data from the entire U.K. FTSE index for the years 1985–2000 are then reported. These findings include the observation of a time-related increase in charitable donations, which is compared with an earlier study to give a 24 year history of charitable donations in the U.K. The findings note little responsiveness of the monetary value of charitable donations to the economic performance of firms. An international comparison over time against U.S. trends is also reported and shows how U.S. corporations have traditionally been more generous than U.K. firms, but that the trend in the U.S. is downwards. Membership of a U.K.-based "tithing" club (the PerCent Club) is shown to be associated with higher profit performance against non-members. Members' charitable contributions against profit are shown to be higher than the FTSE mean although short of the 0.5% target figure in "cash" terms. The paper concludes with a brief discussion of these findings in relation to the theoretical positions advanced for corporate philanthropy.
