On a distribution of Jasso and Kotz

Explicit expressions are derived for the moments and the Gini coefficient of the ring-exponential distribution introduced by Jasso and Kotz ( Statistica Neerlandica , 61 , 2007, 305–328).     

Nonparametric estimation of variance, skewness and kurtosis of the distribution of a statistic by jackknife and bootstrap techniques

While jackknife and bootstrap estimates of the variance of a statistic are well–known, the author extends these nonparametric maximum likelihood techniques to the estimation of skewness and kurtosis. In addition to the usual negative jackknife also a positive jackknife as proposed by BERAN (1984) receives interest in this work. The performance of the methods is investigated by a Monte Carlo study for Kendall's tau in various situations likely to occur in practice. Possible applications of these developments are discussed.     

The development of a work-value model assessing the cumulative impact of individual and cultural differences on managers' work-value systems: empirical evidence from French and British managers

This study is the first attempt in Europe to develop an analytical model, based on multidimensional scaling and regression analysis, which enables the operationalization of cultural concepts related to the work context at both the individual and cultural levels of analysis. The development of the model consists of adapting Schwartz's motivational theory of human values (1992, 1994, 1999) to the work context by testing his theory on the domain of work-values and social behaviour in the workplace. For this purpose, two new questionnaires were developed: 1) a new work-value questionnaire based on both Schwartz's and Hofstede's conceptual frameworks – the purpose of this questionnaire was to enable the assessment of the cumulative impact of both cultural and individual differences, and 2) a new Communication Style Questionnaire which enabled us to establish the cross-cultural validity at the behavioural level of the newly developed workvalue dimensions. The model was empirically tested with a population of French and British managers from two different sectors, bank/insurance and pharmaceutical/healthcare organizations. This was done so that the impact of organizational culture differences could be controlled. In total more than 2,500 questionnaires were collected for statistical analysis. The final four work-value scales (Self-enhancement; Individual dynamics; Consideration for others; Group dynamics) elicited through rigorous five-step analysis successfully achieved the purpose of the model's development.
