Severe departures from normality occur frequently for null distributions of statistics associated with applications of mulLi-response permutation procedures (MRPP) for either small or large finite populations. This paper describes the commonly encountered situation associated with asymptotic non-normality for null distributions of MRPP statistics which does not depend on the underlying multivariate distribution. In addition, this paper establishes the existence of a non-degenerate underlying distribution for which the null distributions of MRPP statistics are asymptotically non-normal for essentially all size structure configurations. It is known that MRPP statistics are symmetric versions of a broader class of statistics, most of which are asymmetric. Because of the non-normality associated with null distributions of MRPP statistics, this paper includes necessary results for inferences based on the exact first three moments of anv statistic in this broader class (analogous to existing results for MRPP statistics). 相似文献

An algorithm is presented for computing the finite population parameters and the approximate probability values associated with a recently-developed class of statistical inference techniques termed multi-response randomized block permutation procedures (MRBP). 相似文献

As many as three iterated statistical model deletion procedures are considered for an experiment.Population model coeff cients were chosen to simulate a saturated 24experiment having an unfavorable distribution of parameter values.Using random number studies, three model selection strategies were developed, namely, (1) a strategy to be used in anticipation of large coefficients of variation (neighborhood of 65 percent), (2) strategy to be used in anticipation of small coefficients of variation (4 percent or less), and (3) a security regret strategy to be used in the absence of such prior knowledge 相似文献

Survey data collected from a southwestern metropolitan area indicate that self-defined politically conservative individuals are less inclined to commit criminal or deviant acts than their liberal or moderate counterparts; however, results from multivariate analyses indicate that measures of self-control and pressure to conform all reduce the effects of political conservatism to nonsignificance. In general, the relationship between political ideology and misbehavior appears to be partly spurious and partly indirectly attributable to the effects of other social and situational factors. Moreover, responsiveness to pressures to conform is not due to self-control. The results provide some challenge to traditional interpretations of misbehavior but they also confirm an important part played by structural/contextual variables. 相似文献

Purpose: This study uses the selection, optimization, and compensation (SOC) model to compare older adults who have given up driving, those who still drive, and those who drive less to identify differences in the three groups. Design and Methods: This cross-sectional study of 281 older adults is part of the Naturally Occurring Retirement Community Demonstration Project. Study participants completed interviews that included questions on demographics, health and functioning, mental health, social support, and current levels of engagement in activities including current driving status. Results: Data suggest that driving retirement is a process and that a substantial number of people are in the transitional stage, where they are less functional than those who still drive and more similar to those who have retired from the road. Implications: Given the similarity of those who drive less to those who have given up driving, front-line professionals and policy makers must work together to ease the transition to driving retirement for those without adequate ability to effectively compensate for their inability to continue to drive safely. 相似文献

When nations fail to agree, can individual citizens make a difference? The third of our post-Copenhagen features is by Jonathan Gilligan, Thomas Dietz, Gerald T. Gardner, Paul C. Stern , and Michael P. Vandenbergh . They look at the effects that voluntary actions by individuals can have, and at the policies that can best encourage such actions. 相似文献

Salem Village, both before and through the witchcraft trials, was a religion-based community, allowing its minister to exert a level of political–economic control over its citizens. During the height of the witchcraft episode, there was an increased demand for ministerial services (salvation) in the Salem area. Recent research has argued that the minister used the witchcraft episode to maintain and build upon personal and corporate wealth. In the years after the witchcraft trials changes were made in the business and legal environment of the surrounding New England region. By transitioning to a more neutral rules system with a larger area of consensus for the system, Salem and the rest of the New England transitioned from the 17th Century traditional, religion-based community to a more rules-based, pro-business one in the 18th Century. 相似文献

We demonstrate the existence and uniqueness of optimal observation schedules for discrete observation of the simple death process. Optimality is framed in the sense of observing the process at times that maximise the Fisher information for the death rate. We examine the relationship of our designs with those obtained by other authors for the simple birth process. A number of interesting properties are uncovered. Practical considerations in the application of these designs in an experimental setting are investigated, and we examine the performance of some approximately optimal designs that are usually simpler to implement. We will show that our optimal designs are highly robust to mis-specification of the death rate. 相似文献

This paper explores the social relationships of wage labour formed or stabilized in British merchant shipping in the course of “off‐shoring” employment in the late‐19th century. It argues that Asian wage‐workers were mobilized for employment on British merchant vessels as “coolies”, i.e. nominally free but mediated labouring subjects who could only be stabilized through legal, penal, social, debt, or other forms of coercion. Once introduced “coolie” relations were not confined to Indian crews. They also affected wage labour relations more generally in British shipping. While occurring against the backdrop of anti‐colonial struggles, the seafaring coolie's transformation into maritime worker was closely mediated by employers and the colonial state and produced hybrid outcomes. The creation of the modern seafaring “coolie” and the nature and context of his transformation into a “worker” thus shed interesting light on wage labour relations in the modern and contemporary global economy. 相似文献
