Three outcomes of personnel practice (rates of discipline, quitting and absence) are analysed. There was no firm association with measures of practices associated with Human Resource Management. By contrast, unionisation was strongly associated with the low use of discipline and low quit rates: union ‘voice’ remains influential in the 1990s. 相似文献

In Western Europe in the last two decades the unemployment rate has increased during cyclical downturns only to persist at or around the higher level in the following phase of economic recovery. One of the most notable exceptions to this pattern of unemployment persistence, often termed hysteresis, is the United States. The following article examines the empirical evidence and the possible theoretical explanations for this difference. 相似文献

Summary Completeness of a family of probability distributions implies its bounded completeness but not conversely. An example of a
family which is boundedly complete but not complete was presented by Lehmann and Scheffe [5]. This appears to be the only
such example quoted in the statistical literature. The purpose of this note is to provide further examples of this type. It
is shown that any given family of power series distributions can be used to construct a class containing infinitely many boundedly
complete, but not complete, families. Furthermore, it is shown that the family of continuous distributions
, is boundedly complete, but not complete, whereU denotes the uniform distribution on [a, b] and {P
ϑ,ϑ ∈ IR}, is a translation family generated by a distributionP
0 with mean value zero, which is continuous with respect to the Lebesgue measure. 相似文献

Summary The excess burden of a tax is the diminution of utility above that which would have occurred had the tax been collected as a lump sum. Computing the excess burden for the 1983 and 1985 Dutch tax and social premium system enables a partial welfare evaluation of the recent changes in the system, the so-called Tweeverdienersmaatregelen. Based on the equivalent and compensating variation, the excess burden as a percentage of the taxes and social premiums for the 1983 and 1985 system are valued at 27010 and 84010, and 37010 and 58010 respectively. This result indicates that, welfare-theoretically, the old system seems preferable to the new one.The author wishes to thank Hans Doodeman, Paul Renaud and Jacques Siegers for their critical remarks on an earlier version of this article. 相似文献

"A projection model based on a multivariate continuous state, stochastic process is presented. The model allows multiple time-varying covariates to be used so parameters can be estimated from time series information on health changes and mortality, and their interaction. Health changes are simulated by altering parameters controlling the age trajectory and diffusion of risk factor means, variances, and covariances....By increasing the information used in projections it may be possible to better (a) anticipate the state of health at extreme ages, (b) forecast changes in health at specific ages over time, (c) stimulate the effects of specific interventions, and (d) determine the sensitivity of outcomes to a range of interventions." 相似文献

The authors study the acceptance of family planning methods according to the level of couple's literacy in 14 states in India during 1986-87, using the Lorenz curve. The Gini Concentration Ratio and Index of Dissimilarity were calculated by level of couple's literacy for vasectomy, tubectomy, IUD, and all method combined. Firstly, analysis found literates to have accepted vasectomy and IUD more than tubectomy. Secondly, among the 3 methods, a high Gini Concentration Ratio was found for vasectomy when the wife was literate. Moreover, when the wife was literate, the Gini Concentration Ratio of IUD acceptance was higher than the acceptance of IUD by the wife whose husband was literate. Thirdly, the same trend was observed when the husband was illiterate. It is therefore clear that the level of a woman's literacy is a key factor in securing the acceptance of male or female methods of family planning. Planners should therefore concentrate on literacy programs for females independently of their age. Increasing the level of female literacy may ultimately help improve the understanding of family planning methods, while these women may also motivate their husbands to undergo vasectomy which will ultimately foster the success of the family planning program. 相似文献
