The Personality Audit (PA) was developed to meet a need for a relatively simple multiple feedback instrument that could clarify the various motivational needs of executives. Using a psychodynamic approach to leadership, the PA allows the test-taker to assess him- or herself in seven personality dimensions important in human behaviour and to identify personal ‘blind spots’. The resulting insights can be used to formulate appropriate leadership development goals. The objective of this paper is to describe the design and psychometric properties of the PA. This instrument, in contrast with other tools that can be used to clarify the inner theatre of individuals, is designed not only to report information given by the test-taker but also to reflect the perceptions of observers representing both the test-taker's public and private spheres. This paper describes in detail the conceptual foundations of the questionnaire, the psychometric methods used to confirm its validity and reliability, and possible directions for future research. 相似文献

This paper seeks to provide the services sector with a focus on the assessment of quality and for this purpose, a technique that may able a quantitative approach to evaluating quality is proposed. The use of the fuzzy sets theory to process data was used, thus allowing a more flexible and suitable insight into the characteristics of the service sector. An extension of the technique for order performance by similarity to the ideal solution was used. This informs managers of the distance from the company $\prime $ s current level of quality, if compared to a company of perfect quality by means of an overall evaluation. The same technique was used to detect changes in the level of quality during the period surveyed by using a stratified assessment. Finally, a practical application of the approach proposed is presented. 相似文献

Abstract. The contribution of this paper is twofold. First, it builds and makes use of long-run data from Sweden on formal education that have never been used to date. Second, it provides a quantitative application of recent theoretical work on the link between demographic changes and economic growth through their effect on education. It concludes that changes in longevity may account for as much as 20% of the observed rise in education over the period from 1800–2000 via a horizon effect, but have little impact on income growth over the period. On the contrary, changes in population density and composition are central, mainly thanks to their effect on productivity. Most income growth over this period would not have materialized if demographic variables had stayed constant since 1800. 相似文献

A two sector model of learning-by-doing measured by means of production aggregated over time and of human capital accumulation in a schooling sector is presented. Time utilization is rival between schooling and learning-by-doing. Depending on the sum of elasticities of the accumulated factors (i.e., of production experience and educational human capital) in both sectors, a situation with or without endogenous growth results. Dynamic optimization of the choice between leisure and working and of the division of human capital between education and production is executed. Transitional dynamics are analyzed for a Cobb-Douglas example and a numerical simulation is performed.JEL classification: C61, D90, O41.Acknowledgements The author would like to thank Eric C.

The methodology in this paper combines an input–output structural decomposition approach with the supply-side perspective of mainstream growth accounting. In explaining the intertemporal change in consumption per worker, three sets of effects are distinguished. First, contributions due to several types of technological changes are considered. Second, effects caused by changes in international trade are discerned. Third, composition effects that reflect structural shifts in demand (including changes in tastes) are quantified. As an empirical illustration, we analyze the developments in the U.K. between 1979 and 1990. 相似文献

While financial globalization does not lack theoretical economic merit, the more far-reaching practical consequences of this phenomenon are often not fully appreciated from the vantage point of North America or the European Union. In particular, globalization can make it more difficult for emerging economies to achieve macroeconomic stabilization. This is especially true if the countries in question have chosen the vehicle of pegged exchange rates as an important element of domestic anti-inflation policy. The chief macroeconomic difficulties for emerging economies in a world of volatile capital flows can include a loss of monetary control, a real appreciation of the domestic currency, and a worsening of economic fundamentals leading to damaging currency crises. This paper concentrates on the recent experience of Brazil as illustrative of the abject plight faced by many developing countries attempting to secure economic stabilization against the background of the present globalized international economy.This paper has benefitted from discussion with participants of the Forty-Sixth International Atlantic Economic Conference, Boston, MA, October 8–11, 1998. 相似文献

We consider a semiparametric competing risk model given by k independent survival times. The paper offers an asymptotic treatment of tests for the semiparametric null hypothesis of equality of the underlying risks. It turns out that modified rank tests are asymptotically efficient for certain semiparametric submodels, where the baseline hazard is a nuisance parameter. In addition, the asymptotic relative efficiency of the present tests is derived. A comparison of asymptotic power functions can then be used to classify various tests proposed earlier in the literature. For instance a chi-square type test is efficient for proportional hazards. Data driven tests of likelihood ratio type are proposed for cones of alternatives. We will consider certain stochastically increasing alternatives as a special example. The paper shows how the concept of local asymptotic normality of Le Cam works for hazard oriented models. 相似文献

Probability theory in fuzzy sample spaces 总被引:2,自引:0,他引:2
This paper tries to develop a neat and comprehensive probability theory for sample spaces where the events are fuzzy subsets of The investigations are focussed on the discussion how to equip those sample spaces with suitable -algebras and metrics. In the end we can point out a unified concept of random elements in the sample spaces under consideration which is linked with compatible metrics to express random errors. The result is supported by presenting a strong law of large numbers, a central limit theorem and a Glivenko-Cantelli theorem for these kinds of random elements, formulated simultaneously w.r.t. the selected metrics. As a by-product the line of reasoning, which is followed within the paper, enables us to generalize as well as to bring together already known results and concepts from literature.Acknowledgement.

For random elements X and Y (e.g. vectors) a complete characterization of their association is given in terms of an odds ratio function. The main result establishes for any odds ratio function and any pre-specified marginals the unique existence of a corresponding joint distribution (the joint density is obtained as a limit of an iterative procedure of marginal fittings). Restricting only the odds ratio function but not the marginals leads to semi-parmetric association models for which statistical inference is available for samples drawn conditionally on either X or Y. Log-bilinear association models for random vectors X and Y are introduced which generalize standard (regression) models by removing restrictions on the marginals. In particular, the logistic regression model is recognized as a log-bilinear association model. And the joint distribution of X and Y is shown to be multivariate normal if and only if both marginals are normal and the association is log-bilinear.Acknowledgements The author thanks both referees for their helpful comments which improved the first draft of the paper. 相似文献

There is a general belief that federal commodity programs restrict adoption of more sustainable production systems. In the
1990 farm legislation, Congress introduced limited planting flexibility to address these concerns and to reduce federal farm
program costs. This program estimates the impact of planting flexibility on selected agricultural sustainability indicators
and its policy implications. Results show that planting flexibility is a necessary but not sufficient condition for implementing
more sustainable production systems. Other factors such as the availability of economically viable alternatives, macroeconomic
conditions, and local resource and environmental concerns need to be considered. Policy reforms can help in achieving economic
and environmental gains only in locations with economically viable alternatives. In other cases, increased research and development
of new systems are needed to achieve desired results. 相似文献
