This research note builds upon recent discussions in this journal in an exploration of different scenarios for the way that critical management education and studies can relate to mainstream management education and studies. It is argued that there is no choice but for there to be a relationship of some sort between the two, albeit of a complex sort. Three scenarios are envisaged. In one, the two approaches largely ignore each other and their relationship is left tacit and covert. In the second, there is an engagement between the two. In the third, critical approaches gain ascendancy and become the mainstream. Whilst fraught with difficulties, the conclusion is that the second scenario, that of engagement, is preferable.  相似文献

This article considers what corporations' attitudes toward women will be in the year 2000, and what women's attitudes toward corporations will be at that time. Women's current position in the workforce is characterized. Consideration is given to the direction today's workplace is taking as it transitions to the start of a new century. Based on current observations and trends, the article explores the needs and desires of the twenty-first century woman. Four major tools available to U.S. corporations preparing to enter the next century are discussed, including family issues, a commitment to innovation, training, and women's contributions to the management of transition.  相似文献

The objective of this paper is to define and compare alternative sampling frames for the representative population coverage as a basis for sample selection in internet surveys. The study aims to provide a methodology for domain weighting and adjustment procedures for free access web surveys that are based on the restricted access surveys. Some basic variables can be proposed for the data adjustment, namely gender breakdown, age groups, and education groups. The application of our work consists of a first stage based on a web survey by an e-mail invitation (restricted access) and a second stage based on a voluntary participation web survey (free access). An advertising company’s registered customer list was taken as the sampling frame population for the first stage. This frame was an electronic e-mail list of the population of registered customers. Two different types of questionnaire were loaded on the company’s internet web site for a month each, for two independent rounds, for testing the visual aspects of the questionnaire design. The restricted access internet survey design relies on probability selection procedures in this study. These results are used with the provided algorithms for the adjustment procedures of free access web surveys. A new methodology is also proposed for the estimation and allocation of the population frame characteristics of adult internet users by gender and age groups. The proposed alternative methodologies will be beneficial tools for future web survey users.  相似文献

成败型产品一次抽样检验方案研究   总被引:2,自引:0,他引:2  
一、引言 抽样检验是产品检验的最基本方式之一。对一次性使用的产品,我们无法整批逐个检验:其次。即使是非破坏性的检验。当产品批量很大时,用于检验的人力、物力、财力都很惊人,并且大量重复劳动容易引起人们的厌倦和疲劳.反而会造成漏检和误检。  相似文献

In many survey situations simple random sampling of units and estimation of a total of interest by the expansion estimator are attractive methods, at least at first sight. Considering cost aspects suggests rather to use multiple stage sampling which, in general, is cheaper, but less effective. The design effect is an adequate criterion of the decrease of efficiency. We discuss this criterion for clusters (primary units) of equal size and derive exact conditions for a decrease of efficiency. The equality condition for cluster sizes seems not to be very restrictive, because in many cases one will be interested in clusters of approximately the same size, or, if sizes differ essentially, the clusters are partitioned into strata according to their sizes and the procedures for different strata are independent, each dealing with clusters of equal size or nearly so. In the context considered the use of the Horvitz–Thompson estimator is quite general. We examine a class of estimators with the Horvitz–Thompson estimator and a straight forward modification of it as special elements. As for the design effect all elements of the class are very similar, as for other aspects such as admissibility there are remarkable differences.  相似文献

In outsourcing situations involving manufacturing and assembly, the sampling of units produced is important since in many situations not all of the units can be tested. Destructive sampling, which commonly occurs in the assembly and manufacturing industry, is a form of sampling where all units produced cannot be tested since the parts are destructively tested. In this situation, sampling techniques are used to determine if an entire lot should be accepted or rejected based on the sampling results. The traditional sampling techniques include single or classical sampling, double sampling, multiple sampling, skip-lot sampling, chain sampling and MIL-STD-105E. The purpose of this paper is to develop a sophisticated technique that monitors quality at a lower cost than traditional methods yet has similar monitoring characteristics in situations where quality is high and tests are destructive. The proposed technique, Destructive Sampling Method for High Quality production processes (DSM-HQ), is based on a cost function, which balances the costs of sampling versus the costs of finding a defect on the field. DSM-HQ assumes to have a Poisson process defect pattern and uses an Empirical Bayesian analysis to allow the researcher to include prior knowledge.  相似文献

This paper considers the problem of unbiasedly estimating the population proportion when the study variable is potential sensitive in nature. In order to protect the respondent’s privacy, various techniques of generating randomized response rather than direct response are available in the literature. But the theory concerning them is developed only under the hypothesis of completely truthful reporting. Actually, the occurrence of untruthful reporting is a prospect in dealing with highly sensitive matters such as abortion or socially deviant behaviors. Illustrating Warner’s [(1965), Journal of the American Statistical Association. 60: 63–69] randomized response technique we show how unbiased estimation of the population proportion can be extended to cover a case when some respondents may lie.  相似文献

This note describes how a convex N-input-M -output production possibility frontier can be locally approximated by means of a flexible Nonseparable Nested Constant-Elasticity-of-Substitution/Constant-Elasticity-of-Transformation (NNCES-CET) restricted profit function. This technique yields a summary representation of technology sets that is globally regular and thus suitable for use in applications where regularity is crucial.  相似文献
