Reverse mandated benefits is a government-mandated policy that requires employees to provide their employers with benefits
that workers would not provide otherwise. Of course, only those benefits would be mandated that are worth more to employers
than they cost, as determined by political authorities. My case for such a policy argues that it is at least as sensible as
policies mandating that employers provide benefits to their employees that would not be provided otherwise. 相似文献

This paper investigates how individuals evaluate delayed outcomes with risky realization times. Under the discounted expected utility (DEU) model, such evaluations depend only on intertemporal preferences. We obtain several testable hypotheses using the DEU model as a benchmark and test these hypotheses in three experiments. In general, our results show that the DEU model is a poor predictor of intertemporal choice behavior under timing risk. We found that individuals are averse to timing risk and that they evaluate timing lotteries in a rank-dependent fashion. The main driver of timing risk aversion is nothing but probabilistic risk aversion that stems from the nonlinear treatment of probabilities. 相似文献

Supporting processes of belonging in supervision and coachingThe contemporary employee has to cope with frequent changes. Not only does he lose his familiar environment, he also has to find ways to familiarize himself with new places and to develop a fresh sense of belonging. This process can be understood and facilitated by interpreting the German concept of “Heimat“ as something we have to create ourselves. First experiences demonstrate the usefulness of this approach in coaching processes. 相似文献

In this paper, the task of determining expected values of sample moments, where the sample members have been selected based on noisy information, is considered. This task is a recurring problem in the theory of evolution strategies. Exact expressions for expected values of sums of products of concomitants of selected order statistics are derived. Then, using Edgeworth and Cornish-Fisher approximations, explicit results that depend on coefficients that can be determined numerically are obtained. While the results are exact only for normal populations, it is shown experimentally that including skewness and kurtosis in the calculations can yield greatly improved results for other distributions. 相似文献

20世纪初所发生的“视觉现代化”(modernising vision)转向源于自19世纪以来传统的视觉概念所发生的深刻变化。它旨在将人们从过时的观看习惯中解放出来,视觉的本质不应主要被理解为给定可见世界的机械再现模式,而应该从根本上被理解为由文化构造的、具有历史多样性的感知数据的生产性过程。现代艺术试图通过艺术品本身来创造一种现代化的视觉形式,艺术作品被定义为实现视觉现代化的手段或工具,画家试图用艺术来表达一种新的视觉观——观看中充斥着时间的流动,而绝不仅是一个明确的视觉顺序的实现;观看不是一个视觉固定化过程,而是更加有意识地、集中地观察世界。从丢勒式的空间中心透视观到塞尚式的时间和空间相结合的多重透视观,后者更加强调了观者的参与和观看的过程,这种观看方式的变化也是人与世界关系的变化。视觉现代化的探讨在今天仍然具有重要的意义(2)。 相似文献

Author of the highly acclaimed Borrowed Time: An AIDS Memoir (1988) and winner of the 1992 National Book Award for his autobiography Becoming a Man: Half a Life Story, Paul Monette died of complications from AIDS in Los Angeles on February 12, 1995. His most recent work, Last Watch of the Night: Essays Too Personal and Otherwise (1994), is his third volume in a trilogy of autobiographical writing on growing up gay, coming-out, and living with AIDS. A graduate of Phillips Academy and Yale University, Monette received a number of awards for his writing and his work as an outspoken voice in the battle against AIDS, including the National Book Award, three Lambda Literary awards, the PEN Center West Freedom to Write Award, and three honorary doctorate degrees, from Wesleyan University, the City University of New York, and the State University of New York at Oswego. A memorial service was held for Monette on Sunday, February 19, 1995, at the Directors Guild of America on Sunset Boulevard in Los Angeles. Paul Monette was 49. 相似文献

In the binary single constraint Knapsack Problem, denoted KP, we are given a knapsack of fixed capacity c and a set of n items. Each item j, j = 1,...,n, has an associated size or weight wj and a profit pj. The goal is to determine whether or not item j, j = 1,...,n, should be included in the knapsack. The objective is to maximize the total profit without exceeding the capacity c of the knapsack. In this paper, we study the sensitivity of the optimum of the KP to perturbations of either the profit or the weight of an item. We give approximate and exact interval limits for both cases
(profit and weight) and propose several polynomial time algorithms able to reach these interval limits. The performance of
the proposed algorithms are evaluated on a large number of problem instances. 相似文献

Dual Career Couples as a form of work-life-integrationThe author discusses the situation of dual career couples, when both are university graduates following an own career. Basing on a respective publication she delineates the current, mostly American research and reports on several German research projects, which endeavour to analyse the relation between gender and inequality in dual career couples. 相似文献
