This study was motivated by a need to empower the Human Resource function to rationally and purposefully monitor and manage the determinants of turnover intention, and through that, the intention to quit of talented employees. A partial talent management structural model was developed, mapping line-manager talent management competencies on the outcomes of job satisfaction, affective commitment and intention to quit. The partial talent management structural model was tested using LISREL. Reasonable to good model fit was indicated for the structural model. Ten of the 24 stated hypotheses were confirmed. The study provides unique insight into the manner in which the talent management competencies are causally related among themselves, and provides support for studies which link affective commitment and intention to quit, as well as job satisfaction and intention to quit. Suggestions for the expansion and elaboration of the existing model are made.
The relationship between economic value added and data envelopment analysis based on financial statements : empirical evidence of South African listed banksSource: Management Dynamics : Journal of the Southern African Institute for Management Scientists 19, pp 29 –41 (2010)More Less
The purpose of the study is to estimate the relationship between bank efficiency and the creation of shareholders' value. Annual financial statement reports are used to estimate technical, allocative and cost efficiency with the aid of two Data Envelopment Analysis (DEA) models (one mainly income statement-based and the other mainly balance sheet-based) for five banks listed on the Johannesburg Stock Exhange (JSE) over a 10-year period. The creation of shareholders' value is estimated by using Economic Value Added (EVA). The study found that there appears to be a weak relationship between EVA values and the efficiency estimates of the two DEA models. In addition, neither of the two DEA models is significantly superior as a driver for shareholders' value. Further research is needed to estimate why the efficient operation of a bank does not necessarily contribute to the creation of shareholders' value. Researchers may consider including different variables in their DEA model(s) or use variables with time lags.

Online auctions are an attractive non-store buying method for many buyers and a selling option for many sellers. In an online auction, sellers must provide a description of the item they want to sell and specify a starting bid amount, bid increment, and so on. Buyers then use this information to base their decisions to bid or not to bid on the item. The research question addressed in this study is: to what extent does information on an auction page determine the success of an online auction (item sold)? To address the research question, information on 2 000 auctions ending in May 2010 was directly obtained from BidorBuy, a major South African third-party online auction site. A multiple logistic regression model was used to investigate the extent to which various types of information contribute to the probability of an auction ending successfully (item sold). The results of the study indicate that the condition of an item, together with the bid step amount, influence the outcome of the auctions, as well as the number of positive ratings of the seller, the seller-defined payment options, and the size of the starting bid.
