This article describes the findings of a study undertaken to shed light on some of the factors that determine the employment of foreign biomedical scientists in the United States by examining their presence at the National Institutes of Health (NIH). NIH was selected as the focus of the study for its unique combination of characteristics. It is a federal agency with the ambiance of academe that carries out biomedical research and training internally while supporting like activities externally through grant‐ and contract‐based linkages with a host of academic institutions and biotechnology firms in the United States and abroad. Over a two‐year period, in‐depth interviews were conducted with more than 200 stakeholders at the NIH campus and elsewhere, as well as ethnographic observations. The study identified several hitherto unreported important functions that NIH plays in facilitating the inflow of talented foreign scientists to meet its manpower needs and those of the broader national economy. 相似文献

In this paper a surrogate to traditional utility optimization is presented. This approach is based on multiple criteria decision making techniques through a theorem which connects utility function optimization with compromise programming. Apart from common assumptions in the literature the only specific assumption underlying the approach seems realistic, and is markedly related to traditional analysis. 相似文献

Supply chain integration (SCI) is a competitive business approach for enterprises that has not been implemented as widely as expected in small and medium-sized enterprises (SMEs). One of the factors explaining this low level of application is the lack of methodologies to develop SCI that fit the characteristics of this type of enterprise. In this article, we present a methodology that enables SMEs to achieve correct SCI in a manner that is simple, straightforward and oriented towards their particular characteristics. Thus, SMEs will be able to align and coordinate the aims, resources, decisions, methods, business processes and employees involved in the supply chain. The methodology addresses the problem of SMEs SCI and it was produced by applying the case study research method to 30 industrial SMEs. The methodology is organised in phases and the activities to be performed, the techniques and supporting tools to be used, as well as the expected outcomes are all described for each phase. With this methodology, it becomes possible to overcome the main barriers that prevent SMEs from achieving a correct integration of their supply chains. In addition to the methodology, this article also outlines the significant benefits observed in the 30 enterprises as a result of its application. 相似文献

We propose measuring individual employability as a weighted average across occupations of a worker’s predicted wage for each occupation. Weights are given by the individual occupational probability distribution. Under this measure, a worker is more employable than another if she has a greater chance to obtain a better paid occupation. After normalization, expected employability corresponds to the population correlation between occupational predicted wages and the chance to obtain employment in these occupations and serves as a measure of the allocative efficiency of labor market. We apply the methodology to Brazil and found that employability increased and became less unequally distributed from 2002 to 2011. We used a decomposition method to investigate the causes of these changes. Although average normalized employability is weakly positive, it has increased for the period, which suggests that there is room for efficiency gains in the allocation of workers to occupations in the Brazilian labor market. 相似文献

The well-known equivalence of Wilcoxon and Mann-Whitney location statistics is herein extended to dispersion tests. Mood (1954) statistic is related to a statistic based on “triplets”. The triplet version of Mood statistic is useful for proving the asymptotic normality (under alternatives) of the test. 相似文献

A Bayesian nonparametric model for Taguchi's on-line quality monitoring procedure for attributes is introduced. The proposed model may accommodate the original single shift setting to the more realistic situation of gradual quality deterioration and allows the incorporation of an expert's opinion on the production process. Based on the number of inspections to be carried out until a defective item is found, the Bayesian operation for the distribution function that represents the increasing sequence of defective fractions during a cycle considering a mixture of Dirichlet processes as prior distribution is performed. Bayes estimates for relevant quantities are also obtained. 相似文献
