Moving Extremes Ranked Set Sampling (MERSS) is a useful modification of Ranked Set Sampling (RSS). Unlike RSS, MERSS allows
for an increase of set size without introducing too much ranking error. The method is considered parametrically under exponential
distribution. Maximum likelihood estimator (MLE), and a modified MLE are considered and their properties are studied. The
method is studied under both perfect and imperfect ranking (with error in ranking). It appears that these estimators can be
real competitors to the MLE using the usual simple random sampling (SRS). 相似文献

In a dynamic environment, organizations often are required to effect major changes in operations. The success of such changes invariably depends upon numerous factors one of which is how the change affects the work environment. Therefore, in planning organizational change it is important to consider the work environment and to objectively evaluate changes in the work environment in a timely fashion so that corrective actions may be formulated if needed. Such framing and monitoring of the organizational change facilitates successful implementation of the organizational change. This paper suggests a measure which may be used in evaluating an organization's work environment. A case is discussed. 相似文献

In this paper, we introduce a multivariate generalization of the population version of Gini's rank association coefficient,
giving a response to this open question posed in [4]. We also study some properties of this version, present the corresponding
results for the sample statistic, and provide several examples. 相似文献

We state sufficient conditions for asymptotic normality of convergent estimates of the conditional mode, irrespective of data dependence, and give an application to α-mixing stationary processes. 相似文献

We examine the role of managers in controlling the positive impact of stakeholder management (SM) on firm financial performance (FP) in the long term. We develop and test competing hypotheses on whether managers act as “good citizens” or engage in “self‐dealing” when allowed greater discretion. We test our assertions using dynamic panel data analysis of a sample of 806 U.S. public firms operating in 34 industries over 5 years (2005–2009). Our results indicate a nuanced influence of managerial discretion contexts on the SM‐FP relationship. We infer that given more latitude in decision making, as long as the “going is good” managers act as good citizens, but otherwise they revert to managerial self‐dealing. In light of our results, firms designing governance mechanisms to encourage managers to balance the needs of both shareholders and stakeholders must remain cognizant of contextual contingencies. 相似文献

The issue of employment has become a crucial one in Algeria. Not only does the economy no longer offer opportunities for jobseekers; economic reforms have led to countless public-sector businesses being wound up, putting thousands of people out of work. Against this background, a system of temporary unemployment benefits has been introduced, though its effectiveness has been sharply criticized. How many of the occupations targeted by the legislation setting up the system are actually covered by Algeria's unemployment insurance system, and on what terms? What obstacles are there to the full realization of this system's objectives, and how effective is it in an economic and financial sense? The unemployment insurance system is traditionally accused of clogging up the machinery of employment and preventing a return to a competitive labour market. There are also those who believe that this system helps to foster voluntary unemployment and encourages people to spend more time on leisure pursuits. Our article considers all these views. At the end the reader will also find brief details of unemployment insurance in South Africa and Egypt. 相似文献

Our “Restated diversification theorem” (Skogh and Wu, 2005) says that risk-averse agents may pool risks efficiently without assignment of subjective probabilities to outcomes, also at genuine uncertainty. It suffices that the agents presume that they face equal risks. Here, the theorem is tested in an experiment where the probability of loss, and the information about this probability, varies. The result supports our theorem. Moreover, it tentatively supports an evolutionary theory of the insurance industry—starting with mutual pooling at uncertainty, turning into insurance priced ex ante when actuarial information is available. 相似文献

Older people, work and equal opportunity 总被引:1,自引:0,他引:1

People in industrialized countries are living longer, having fewer children and retiring sooner. The proportion of older people in the population is rising; their labour force participation is declining. These trends are arousing apprehensions about future labour supply and pension financing as contributor/beneficiary ratios decrease. A widely advocated policy response is to seek higher participation rates, especially by raising pensionable ages and restricting early retirement. Little has been done to improve the labour market position of seniors. Three-pronged action is needed: promoting training, placement and workplace flexibility; changing attitudes through education and information; and prohibiting age discrimination in employment. 相似文献

In this article optimality of experimental design for fitting a lower-order polynomial to a higher order response function for the situation in which observations may be subject to shift in means as well as in variances is considered. It is found that Karson, Manson and Hader‘s (1969) optimum designs provide pro-tection, in some sense, against model inadequacies even when observations are subject to shift in means and variances. 相似文献
