On the Discrete Version of the Aumann–Shapley Cost‐Sharing Method

Each agent in a finite set requests an integer quantity of an idiosyncratic good; the resulting total cost must be shared among the participating agents. The Aumann–Shapley prices are given by the Shapley value of the game where each unit of each good is regarded as a distinct player. The Aumann–Shapley cost‐sharing method charges to an agent the sum of the prices attached to the units she consumes. We show that this method is characterized by the two standard axioms of Additivity and Dummy, and the property of No Merging or Splitting: agents never find it profitable to split or to merge their consumptions. We offer a variant of this result using the No Reshuffling condition: the total cost share paid by a group of agents who consume perfectly substitutable goods depends only on their aggregate consumption. We extend this characterization to the case where agents are allowed to consume bundles of goods.     

Inference in a Binary Response Model with Applications to Data Analysis*

Standard errors of the coefficients of a logistic regression (a binary response model) based on the asymptotic formula are compared to those obtained from the bootstrap through Monte Carlo simulations. The computer intensive bootstrap method, a nonparametric alternative to the asymptotic estimate, overestimates the true value of the standard errors while the asymptotic formula underestimates it. However, for small samples the bootstrap estimates are substantially closer to the true value than their counterpart derived from the asymptotic formula. The methodology is discussed using two illustrative data sets. The first example deals with a logistic model explaining the log-odds of passing the ERA amendment by the 1982 deadline as a function of percent of women legislators and the percent vote for Reagan. In the second example, the probability that an ingot is ready to roll is modelled using heating time and soaking time as explanatory variables. The results agree with those obtained from the simulations. The value of the study to better decision making through accurate statistical inference is discussed.     

VALIDATION OF EXPERT SYSTEMS- WITH APPLICATIONS TO AUDITING AND ACCOUNTING EXPERT SYSTEMS*

This paper proposes a set of definitions for the concepts “validation” and “assessment” applied to expert systems (ESs). It develops a framework for this validation and demonstrates the framework on existing accounting and auditing ESs to elicit some of the research issues involved in ES validation. Validation is critical to the design and implementation of decision-making ESs. In a setting where objectivity is sought and variance is avoided, validation ascertains what a system knows, knows incorrectly, or does not know. Validation ascertains the system's level of expertise and investigates the theoretical basis on which the system is based. It evaluates the reliability of decisions made by the system. The validation framework developed in this paper is research methods. It is designed to reflect the unique aspects of ESs (in contrast to other types of computer programs) and can be used by ES developers as a basis from which to perform validation and by researchers as a framework to elicit research issues in validation.     

Notes and Communications “A DECISION THEORY EXAMPLE IN FOOTBALL”: A COMMENT*

Janssen and Daniel analyzed the choice between a one- or a two-point conversion for a particular game situation in college football. Their decision criteria was maximum expected utility based on a von Neumann-Morgenstern utility function defined over the games outcomes. An alternative approach based on a stochastic dominance criterion is presented that does not rely on knowledge of the relative importance of tying vs. winning; rather, it relies on a notion of consistency in the sequential problem.     

A DECISION THEORY EXAMPLE IN FOOTBALL

In the 1967 Harvard-Cornell football game, Harvard was ahead 14–0 late in the game when Cornell scored two touchdowns. On both occasions, Cornell tried and failed on the two-point conversion attempt and lost the game 14–12. Postgame arguments were divided on the merits of Cornell's strategy. For this frequently occurring scenario in college football, we derive a maximum expected utility decision rule for the decision of kicking versus running/passing based on the relative utility of a win, a tie, or a loss and the probabilities of success with a kick as opposed to a run/pass.     

Taking the reins: A grounded theory study of women's experiences of negotiating water immersion for labour and birth after a previous caesarean section

BackgroundWomen seeking a vaginal birth after a caesarean section (VBAC) frequently want to keep their subsequent labour and birth free from intervention. Water immersion (WI) during labour is potentially an effective tool for women having a VBAC for its natural pain-relieving properties. However, negotiating access to WI can be difficult, especially in the context of VBAC.AimTo explore women's experiences of negotiating WI for labour and birth in the context of VBAC.MethodologyThis Grounded Theory study followed Strauss and Corbin's framework and analytic process. Twenty-five women planning or using WI for their VBAC labour or birth were recruited from two midwifery practices and a social media group across Australia. Participants were interviewed during pregnancy and/or postnatally.Findings‘Taking the reins’, the core category explaining the women’s experiences of assuming authority over their birth, comprised five categories: ‘Robbed of my previous birth experience’; ‘My eyes were opened’; ‘Water is my tool for a successful VBAC’; ‘Actioning my choices and rights for WI’, and ‘Empowered to take back control’. ‘Wanting natural and normal’ was the driving force behind women’s desire to birth vaginally. Two mediating factors: Having someone in your corner and Rules for birth facilitated or hindered their birth choices, respectively.ConclusionThe women became active participants in their healthcare by seeking information and options to keep their birth experience natural and normal. Support from other women and advocacy in the form of continuity of midwifery care was crucial in successfully negotiating WI for their VBAC when navigating the complex health system.     

中国城市老人自杀问题分析

文章将在老龄化和城市变迁的背景下审视中国城市老人自杀的问题。笔者对中国自杀数据的整理和分析显示,中国城市老人在千禧年后的自杀率超过2000年之前的年均水平。以往的研究通常将久病厌世和家庭纠纷视为中国城市老人自杀的主要诱因。笔者却认为,相对剥夺感的大小可以强化或缓解这两个导致自杀的驱动力,所以应该在相关的分析中加以重视。为此,本文将集中分析医保的缺乏和城市开发对城市老人自杀问题的影响。     

Forward and backward, horizontal and vertical: Transformation of occupational credentialing in the schooled society

Underdeveloped theory about educational credentialing flies in the face of the immense practice of educational degree attainment by ever increasing proportions of each new generation, and the ensuing pervasive belief in the power of degrees to both allocate individuals in the labor market and to serve as job requirements throughout the occupational structure. Considering educational credentialing at the center of the educational revolution in postindustrial society, a new theoretical argument is developed from the premise that education as an institution provides the logic by which educational credentialing becomes evermore legitimate, more so than from forces outside the institution itself such as the economy and labor market demand. In support of the proposed theory of credentialing, multiple sets of new findings about education, occupations, and work show that the common negative notion of run-away educational credentialism does not fit empirical trends. Second, as a function of widely held beliefs about education in postindustrial society, four institutional processes by which educational credentialing has deeply integrated into the occupational structure are described and illustrated with empirical observations and analyses. Lastly, consequences of the rapid and robust educational transformation of occupational credentialing for future sociological inquiry into social stratification and mobility are discussed.     

新世纪管理与组织研究面临的挑战

近一个世纪来,管理理论和组织学研究促进了一系列根本性改变的表述,使得管理者们在其职业生涯中必须大量地学习、学习、再学习。人们会认为,在大学商学院里,应该是组织学研究者们而不是其他领域的专家,引导着适应变化环境的新范式的发展。然而,本文将指出组织学范式的研究与经营实践迄今为止基本上是相互分离的。本文还将详细说明,尽管存在着这种分离,经营范式文献对组织学研究和引导它的理论范式还是产生了相当大的影响,特别是在这个“实用知识”越来越受重视的年代。
