The potential of and obstacles to agriculture in the Southern African Development Community

This article focuses on the potential of and obstacles to agriculture in the Southern Afri can Development Community. The potential for horizontal and vertical expansion of agri cultural production is discussed Specific attention is given to problems of data availabil ity, macroeconomic policy and trade in the region, inadequate research, technology de velopment and extension, human capital and land tenure. The article integrates the con tributions of an African Development Bank study, regional policy and macroeconomic programmes, international studies on potential population‐supporting capacity and re gional rural and agricultural programmes.     

Determinants of state equity ownership,and its effect on value/performance: China's privatized firms

Evidence on the relationship between state ownership and performance in China's privatized firms is convex, concave and linear. Hence, the nature of this relationship is not resolved. This study examines this relationship for a larger, more recent sample of 4315 firm year observations of privatized Chinese firms during 1996–2003. Results support the hypothesis of a convex relationship between state ownership and performance showing benefits from strong privatization and state control. Not only is ownership structure found to affect performance, but also ownership concentration and balance of power jointly affect performance. Chinese firms with mixed control show significantly poorer performance than state or private controlled firms affirming the problem of ambiguity of ownership control, property rights, agency issues, profits and welfare objectives. New determinants of state ownership in China's firms are strategic importance, legal ownership, profitability, and market performance. Privatization benefits because there is a causal relation between ownership and performance.     

Analysis of ultra-high-frequency financial data using advanced Fourier transforms

This paper presents a novel application of advanced methods from Fourier analysis to the study of ultra-high-frequency financial data. The use of Lomb–Scargle Fourier transform, provides a robust framework to take into account the irregular spacing in time, minimising the computational effort. Likewise, it avoids complex model specifications (e.g. ACD or intensity models) or resorting to traditional methods, such as (linear or cubic) interpolation and regular resampling, which not only cause artifacts in the data and loss of information, but also lead to the generation and use of spurious information.     

Are Men Always Picked Over Women? The Effects of Employment Equity Directives on Selection Decisions

This study replicates and extends previous work by Oppenheimer and Wiesner [1990, Sex discrimination: Who is hired and do employment equity statements make a difference? Proceedings of the 11th Annual Conference of the Administrative Sciences Association of Canada, Personnel and Human Resources Division], and examined the effects of minority qualifications on hiring decisions, the effects of employment equity directives when minority candidates are less qualified and the effects of different types and strengths of employment equity directives on hiring decisions. The results indicate that when employment equity is in place, people are increasingly more likely to hire underrepresented group members, to the extent that they are more qualified. Men appear to be treated in a positively biased manner, and are more likely to be hired when they are less qualified. Women are less likely to be hired when they are under-qualified, and in the absence of employment equity directives or when there is a suggestion that women are underrepresented. Moreover, when␣employment equity directives are strengthened, there appears to be a subtle backlash for women but not for men. Eddy S. Ng is an assistant professor at Trent University.

Does corruption increase emerging market bond spreads?

We study the relationship between corruption and borrowing costs for governments and firms in emerging markets. Combining data on bonds traded in the global market with survey data on corruption compiled by Transparency International, we show that countries that are perceived as more corrupt must pay a higher risk premium when issuing bonds. The global bond market ascribes a significant cost to corruption: an improvement in the corruption score from the level of Lithuania to that of the Czech Republic lowers the bond spread by about one-fifth. This is true even after controlling for macroeconomic effects that are correlated with corruption. We find little evidence that investors became more sensitive to corruption in the wake of the Asian financial crisis.     

Retaining volunteers for the cause: Hope and pride associated with cause-related charity events in cancer control

Special charity events are an important source of revenue for non-profit organisations in cancer control yet volunteering is declining and turnover is high. Experiences at cause-related events may influence retention, particularly emotions connected to the cause and ceremonies which honour cancer survivors and remember loved ones. We explore the degree to which emotions associated with cause-related volunteering and collective action in the literature are felt in response to Relay For Life and what emotions predict three indicators of retention: intention to return for future events, satisfaction with volunteering, and organisational commitment. Volunteers (n = 410) completed a cross-sectional survey at Relay For Life events in Queensland, Australia. Multiple regression analyses examined whether emotions associated with events predicted each indicator of retention, adjusting for number of years spent volunteering for events. Sixty-two percent reported an intention to return the following year. The most commonly reported event-related emotions were hope, pride, and empathy (62–69%). Intention to return, satisfaction, and commitment were each significantly predicted by hope and pride. The findings suggest special charity events in cancer control could retain volunteers by fostering pride and hope (e.g., for a cancer free future); however, future prospective research which examines the mechanisms of these relationships is warranted.     

Consumer perceptions of risks of chemical and microbiological contaminants associated with food chains: a cross-national study

The development and implementation of effective systems to identify vulnerabilities in food chains to chemical and microbiological contaminants must take account of consumer priorities and preferences. The present investigation attempted to understand consumer perceptions associated with chemical and microbiological contaminants in four specific food chains (drinking water, farmed salmon, chicken and milk powder). To this end, ten focus group discussions were held in five different countries (Poland, Ireland, the Netherlands, France and Brazil). Consumers expressed higher concerns about chemical, as compared with microbial, contaminants. Chemical contaminants were more strongly associated with the potential for severe consequences, long-term effects and lack of personal control. Traceability was considered by consumers as a useful tool that offers the potential to improve consumer confidence in food safety.
