Risk analysis of new maize technology in Zaire: a portfolio approach

Risk associated with the adoption of new maize technology and the impact of mandatory cotton production on traditional farmers in the Kasai Oriental Region of Zaire are evaluated within a portfolio context using a quadratic programming model. Seasonal net returns for farm plans including four levels of maize technology in combination with staple food crops are evaluated, with and without mandatory cotton production. The results indicate that cropping systems that include new maize technology are risk-efficient relative to local maize varieties while mandatory cotton production is not risk-efficient at the prevalent price and yield levels in the farming system.     

The Learning Transfer System Inventory (LTSI) translated into French: internal structure and predictive validity

The Learning Transfer System Inventory (LTSI, Holton et al., 2000 ) considers 16 factors likely to influence the transfer of training to the workplace. The purpose of this study is to translate the Learning Transfer System Inventory into French and to examine (1) the internal structure of the translated instrument; and (2) its predictive validity. The Learning Transfer System Inventory was administered to 328 participants from six companies during the week following the end of a training program. The transfer questionnaire was filled in by 106 of those participants 1–3 months later. The results showed that a principal component analysis reveals a factor structure very similar to the original structure: the 16 original factors are replicated. Second, seven factors display statistically significant correlations with transfer: learner readiness, motivation to transfer, transfer design, opportunity to use, transfer‐performance expectations, performance‐outcomes expectations and performance self‐efficacy. Comparisons with four similar previous studies allow us to draw directions for future research on the instrument.     

Managing temporary staffing services: selecting the right agency

The internationalization journey of a high‐tech cluster

We examine the internationalization processes of a sample of photonics companies, using in‐depth interviews conducted with twenty‐two CEOs. The texts of these interviews were appraised by using content analysis, combined with a grounded theory approach. In this way, the internationalization theory was critiqued and some insights developed into the international strategy process. Some salient findings emerged, such as that cluster externalities had a positive impact on the internationalization of firms within the cluster, and the degree of strategic vulnerability that cluster firms faced from developing‐country competitors. These findings are discussed in relation to their research and managerial implications. © 2005 Wiley Periodicals, Inc.

A longitudinal analysis of racial wage differentials for young nonfarm rural workers

A longitudinal data base is used to estimate racial wage differentials for young nonfarm rural workers for 1968, 1973, and 1978. The empirical results indicate the existence of large wage differentials between young white and young black nonfarm rural workers of both sexes. The results also indicate that the wage differential for young men has increased over time while the differential for young women has decreased slightly over time.     

Gold options,an attractive investment instrument for the non-U.S. investor — the case of the Belgian and Dutch investor

Summary Gold has always been an investment instrument whose popularity is closely linked to economic and political instability. Since gold transactions occur in U.S. dollars any investor with a non-U.S. dollar base currency will therefore assume exchange risk exposure. Empirical evidence is given that the gold price has historically varied inversely with the strength of the U.S. dollar. The investor whose base currency is not the dollar, i.e. the Belgian franc or Dutch guilder, incurs less risk when investing in gold than his dollar counterpart.
