A review of the randomized response model introduced by Warner (1965) is given, then a randomized response model applicable to continuous data that considers a mixture of two normal distributions is considered. The target here is not to estimate any parameter, but rather to select the population with the best parameter value. This article provides a study on how to choose the best population between k distinct populations using an indifference-zone procedure. Also, this article includes tables for the required sample size needed in order to have a probability of correct selection higher than some specified value in the preference zone for the randomized response model considered. 相似文献

A recent article by Byrd and Turner (2001) reported that interpersonal skills on the part of information systems personnel had a negative influence on the success of systems as measured by competitive advantage. Several reasons were forwarded to account for this unexpected result, including lack of richness in the measure of these skills, the use of strategic success measures, the true complexity of interpersonal relations within an organization, and the sample of CIOs who may have a bias in favor of technical skills. We address these concerns by incorporating a set of communication skills into the interpersonal skills set, sampling users for a different set of stakeholders, and employing a more complex model based on theories of expectation. The results indicate that the impacts of interpersonal skills on system success is not a simple function of the perceived level of the IS staff's skill proficiency but is also determined by the understood expectations of skill requirements. 相似文献

This is a study of single and parallel machine scheduling problems with controllable processing time for each job. The processing time for job j depends on the position of the job in the schedule and is a function of the number of resource units allocated to its processing. Processing time functions and processing cost functions are allowed to be nonlinear. The scheduling problems considered here have important applications in industry and include many of the existing scheduling models as special cases. For the single machine problem, the objective is minimization of total compression costs plus a scheduling measure. The scheduling measures include makespan, total flow time, total differences in completion times, total differences in waiting times, and total earliness and tardiness with a common due date for all jobs. Except when the total earliness and tardiness measure is involved, each case the problem is solved efficiently. Under an assumption typically satisfied in just-in-time systems, the problem with total earliness and tardiness measure is also solved efficiently. Finally, for a large class of processing time functions; parallel machine problems with total flow time and total earliness and tardiness measures are solved efficiently. In each case we reduce the problem to a transportation problem. 相似文献

The nucleolus linear programming (LP) method for allocating joint costs associated with a shared resource often stops short of uniquely specifying all savings allocations. Barton [1] recently presented the minimum total propensity to disrupt (MTPD) as a secondary criterion for uniquely determining those allocations not provided by the initial LP solution. Barton demonstrated the uniqueness of his solution on a specific example with a four-entity grand coalition. We show a practical approach for implementing Barton's two-step procedure. Our purpose is to make the nucleolus/MTPD model readily accessible to a wide range of practitioners using commonly available spreadsheet tools. We also demonstrate the global optimality of the allocations that the model provides. 相似文献

A sequential time-variation method is utilized in an attempt to detect changes over time in the effectiveness of market communication for an ethical drug. Sudden changes are indicated at three different points in time, and two of these are confirmed by subsequent analysis and information. Gradual changes are also indicated, but these are not confirmed by market information or statistical analysis. 相似文献

In a recent issue of Decision Sciences, Raiborn and Harris [2] discussed the integration of inventory and product sales-mix models. While they formulated a model which reflected some of the interactions between product sales-mix and inventory decisions, the purpose of this note is to point out deficiencies in their decision rule analysis for solving such integrated models. 相似文献

Conceptualization of national human resource development (NHRD) emphasizes that it is an ongoing development process of the individual that is shaped by context. However, the extant literature has focused primarily on describing and evaluating NHRD policies and interventions in different countries with limited consideration of NHRD across the lifespan and the interaction of life stage with context. Using ecological systems theory (EST) and a lifespan development perspective (LDP), we present a systematic review of the NHRD literature based on 310 sources. We identify key themes and gaps in research across the lifespan and at distinct levels of the ecological system. We build on this review to suggest future research informed by both EST and an LDP. We propose a future research agenda focused on several key areas, including: the developing individual as the primary focus of NHRD; the dynamic relationship between NHRD microsystems and how this evolves over time; the exosystem and macrosystem, which provide the context of the NHRD development experience for the individual over their lifespan; and the imperatives of directing research attention to top-down and bottom-up influences within the ecological system. We also propose three methodological innovations to address many of the questions raised by our review, drawing on national archive databases, the use of historical methods and a focus on longitudinal data analysis. Finally, we highlight the practical implications of our analysis for ecosystem and microsystem NHRD actors. 相似文献
