工作要求—资源模型的缓压效应受到组织与学者的关注,文章就该模型以压力主体无差异性为前提下实证结果的不一致性,引入个体能力信念变量——自我效能感,从个体与环境匹配的角度,提出自我效能感与工作资源的匹配,扩展工作要求—资源模型。问卷分析结果显示,自我效能感与工作资源对工作要求与工作压力关系的联合调节效应显著,进而得出以下结论:高自我效能感员工有能力且有意愿利用丰富的工作资源积极应对压力刺激;低自我效能感员工对自身能力缺乏信心且态度消极,在低工作资源情境即组织对工作资源代为控制下,更能有效缓解压力刺激。  相似文献

杨慎在哲学上主张“合性情”,反对将“性”“情”割裂来谈,同时又强调“以性统情”,使情欲在性的指引下得到合理发展与满足。杨慎“约情合性”“缘情绮靡”“含蓄蕴藉”的诗学主张便是这种“性情”观的体现。他还以自己的创作部分地实践了这种诗学观念,从而形成一种“穰丽婉至”的诗风。  相似文献

A new discrete family of probability distributions that are generated by the 3 F 2 function with complex parameters is presented. Some of the properties of this new family are studied as well as methods of estimation for its parameters. It affords considerable flexibility of shape which turns the distribution into an appropriate candidate for modeling data that cannot be adequately fitted by classical families with fewer parameters. Finally, three examples in the fields of Agriculture and Education are included in order to show the versatility and utility of this distribution.  相似文献

In this article, another version of the generalized exponential geometric distribution different to that of Silva et al. (2010 Silva , R. B. , Barreto-Souza , W. , Cordeiro , G. M. ( 2010 ). A new distribution with decreasing, increasing and upside-down bathtub failure rate. Computat. Statist. Data Anal. 54: 935–944 . [Google Scholar]) is proposed. This new three-parameter lifetime distribution with decreasing, increasing, and bathtub failure rate function is created by compounding the generalized exponential distribution of Gupta and Kundu (1999 Gupta , R. D. , Kundu , D. ( 1999 ). Generalized exponential distributions . Austral. NZ J. Statist. 41 ( 2 ): 173188 .[Crossref], [Web of Science ®] [Google Scholar]) with a geometric distribution. Some basic distributional properties, moment-generating function, rth moment, and Rényi entropy of the new distribution are studied. The model parameters are estimated by the maximum likelihood method and the asymptotic distribution of estimators is discussed. Finally, an application of the new distribution is illustrated using the two real data sets.  相似文献

This paper considers the building of stochastic models and the related analysis of discrete data in two biological problems, The first arises from the reproduction of yeast cells, while the secondis concerned with the aggregation of nucleoli. Galton-Watson and aggregation models are constructed for the respective processes and their goodness of fit to the data tested  相似文献

Ever since R. A. Fisher published his 1936 article , "Has Mendel's Work Been Rediscovered?", historians of both biclogy and statistics have been fascinated by the surprisingly high conformity between Gregor (Johann) Mendel's observed and expected ratios in his famous experiments with peas. Fisher's calculatftl x2 statistic of the experiments, taken as a whole, suggested that results on a par or better than those Mendel reported coultl only be expected to occur about three times in every 100,000 attempts. The ensuing controversy as to whether or not the good Father "sophisticated" his data has continued to this very day. In recent years the controversy has focused upon the more technical question of what underlying genetic arrangement Mendel actually studied.

The statistical issues of the controversy are exam:.led in am historical and comparative perspective. The changes the controversy has gone through are evaluated, and the nature of its current, more biological, status is briefly discussed.  相似文献

A family of distributions labelled as Poisson v Katz is formulated, which includes, as particular or limiting cases, the Negative Binomial, Neyman Type A, Poisson v Pascal, and Poisson v Binomial. Thus, while analyzing data, estimating the parameters in the Poisson v Katz family obviates the necessity of having to choose from among the particular or limiting cases. In this article minimum chi-square estimators are presented and their asymptotic relative efficiency obtained. An example is presented to illustrate the procedure  相似文献

ABSTRACT

A bivariate distribution, whose marginal distributions are truncated Poisson distributions, is developed as a product of truncated Poisson distributions and a multiplicative factor. The multiplicative factor takes into account the correlation, either positive or negative, between the two random variables. The distributional properties of this model are studied and the model is fitted to a real life bivariate data.  相似文献

In this paper we develop a technique that is useful in goodness of fit problems with nuisance location and scale parameters. Using Basu's lemma, we transform the sample so that it is independent of the nuisance parameters. The technique will be illustrated by several examples, a discussion of the efficiency of the proposed procedure, and some concluding remarks will given.  相似文献
