The problem of allocating the sample numbers to the strata in multivariate stratified surveys, where, apart from the cost involved in enumerating the selected individuals in the sample, there is an overhead cost associated with each stratum, has been formulated as a non-linear programming problem. The variances of the posterior distributions of the means of various characters are put to restraints and the total cost is minimized. The main problem is broken into subproblems for each of which the objective function turns out to be convex. When the number of subproblems happens to be large an approach has been indicated for obtaining an approximate solution by solving only a small number of subproblems. 相似文献

ϕ-divergence statistics quantify the divergence between a joint probability measure and the product of its marginal probabilities
on the basis of contingency tables. Asymptotic properties of these statistics are investigated either considering random sampling
or stratified random sampling with proportional allocation and independence among strata. To finish same tests of hypotheses
of independence are presented.

In this paper we illustrate how certain design problems can be simplified by reparametrization of the response function. This alternative viewpoint provides further insights than the more traditional approaches, like minimax, Bayesian or sequential techniques. It will also improve a practitioner’s understanding of more general situations and their “classical” treatment. 相似文献

This study compares the use of flexible work practices in wholly owned South African (SA) companies with that in foreign-owned companies. Data were obtained from questionnaire results of a study conducted by Horwitz and Franklin (1996) of flexible work practices in SA organizations. The questionnaire was used as part of a collaborative research project involving three countries (Brosnan et al ., 1996). It was found that SA-owned companies use certain flexible work practices to a lesser extent than foreign-owned companies. This was found to be the case particularly in the use of numerical forms of flexibility, such as sub-contractors/consultants and the use of temporary employees. Use of subcontractors/consultants and temporary staff agencies was found to be the greatest in partially foreign-owned companies. A larger proportion of foreign-owned companies have lower labour costs than do SA-owned companies. This has, however, not been as a result of the greater use of flexible work practices. Foreign-owned companies make more joint decisions with unions than do SA-owned companies when changing work practices. 相似文献

This exploratory study examines how expatriate management practices differ with respect to three international management strategies (local, centralised or global) in 27 mature multinational corporations. In particular, this study examines the categories of expatriate assignments, the strategic integration of expatriate assignments into leadership development and the types of human resource practices that firms utilise to manage expatriates. Results indicate that organisations differentially assign expatriates based on the firm's respective international management strategy. Firms with a global management strategy made greater use of developmental expatriates, had a greater number of senior managers with expatriate experience and had a stronger focus on leadership development through expatriation. Firms did not differ with respect to their use of expatriate management practices based on their international management strategy. 相似文献

The potential of EDI is virtually unlimited, but the success of any EDI initiative hinges on its ability to directly support strategies that achieve your institution's business objectives. At its most fundamental level, EDI technology automates current business practices, speeding up the exchange of business information. This application of EDI most often is found in a hospital's material management department. But EDI integrated internally within a hospital and externally with suppliers and vendors has the potential to go beyond simple automation and to transform processes. This is where the full value of EDI can be realized. No matter which level of EDI participation hospital management decides is appropriate to fulfill its business objectives and strategies, EDI will affect the entire institution's exchange of information with its internal and external audiences. The question management must answer is: Will the hospital's EDI strategy be offensive and managed, or defensive and reactive? Today's environment leaves no room for a \"no-strategy\" EDI option. The options are either to proactively shape EDI, or reactively play catch-up. EDI can work for you. Adequately developing an EDI game plan in support of your business objectives and calling on your suppliers and other trading partners to work with you will ensure EDI is an asset to your facility. 相似文献

Expatriate development has become a critical issue for multinational enterprises (MNEs). There is substantial empirical research on expatriate management in the West but little on Asia, and comparative studies are lacking. This article presents findings from an empirical study on the training and development of expatriates from Singapore, Japan, Korea, Germany, and the United States. The study provides significant information on program types, content, duration, delivery mode, and providers. © 2000 by Jossey‐Bass, A Publishing Unit of John Wiley & Sons, Inc. 相似文献

A Jump-diffusion Model for Exchange Rates in a Target Zone 总被引：1，自引：0，他引：1
We propose a simple jump-diffusion model for an exchange rate target zone. The model captures most stylized facts from the existing target zone models while remaining analytically tractable. The model is based on a modified two-limit version of the C OX , I NGERSOLL and R OSS (1985) model. In the model the exchange rate is kept within the band because the variance decreases as the exchange rate approaches the upper or lower limits of the band. We also consider an extension of the model with parity adjustments, which are modeled as Poisson jumps. Estimation of the model is by GMM based on conditional moments. We derive prices of currency options in our model, assuming that realignment jump risk is idiosyncratic. Throughout, we apply the theory to EMS exchange rate data. We show that, after the EMS crisis of 1993, currencies remain in an implicit target zone which is narrower than the officially announced target zones. 相似文献
