First and second best voting rules in committees   总被引:2,自引:0,他引:2  
A committee of people with common preferences but different abilities in identifying the best alternative (e.g., a jury) votes in order to decide between two alternatives. The first best voting rule is a weighted voting rule that takes the different individual competences into account, and is therefore not anonymous, i.e., the voters’ identities matter. Under this rule, it is rational for the committee members to vote according to their true opinions, or informatively. This is not necessarily true for an anonymous voting rule, under which members may have an incentive to vote non-informatively. Thus, strategic, sophisticated voters may vary their voting strategies according to the voting rule rather than naively voting informatively. This paper shows that the identity of the best anonymous and monotone (i.e., quota) voting rule does not depend on whether the committee members are strategic or naive or whether some are strategic and some are naive. One such rule, called the second best rule, affords the highest expected utility in all cases.

This review explores the literature on the concept of work in unemployment and its relationship to health. A range of literature about the activities of unemployed people is reviewed and discussed with reference to three questions: What do unemployed people do?, What activities are associated with the health of unemployed people? and Do unemployed people work? From the literature, two groups of unemployed people are described: those who are characterised by active patterns of activity and those characterised by passive patterns. It is argued that the active group is psychologically healthier than the passive group. Concepts of work in both groups of unemployed individuals are presented, arguing that the active group seeks to replace employment with other work activities and that the passive group are engaged in work also, but that this presents as fret and preoccupation about their situation. These concepts of work are presented in the context of three major theoretical models of the personal impact of unemployment. Finally, implications for practice and directions for future research are suggested.  相似文献

Providing care for an aged parent has immediate financial, emotional, psychological, and physical consequences for the primary caregiver. This pilot study of 138 middle aged and older females analyzes the long term financial consequences of providing care to aged relatives for female caregivers. The impact of this disruptive life event (e.g., caring for an aged relative) on retirement planning among middle aged and older adult women was analyzed using quantitative data collected from women residing in the Midwest region of the United States.  相似文献

The main object of this paper is to provide the logical machinery needed for a viable basis for talking of the consequences, the content, or of equivalences between inconsistent sets of premisses.With reference to its maximal consistent subsets (m.c.s.), two kinds of consequences of a propositional set S are defined. A proposition P is a weak consequence (W-consequence) of S if it is a logical consequence of at least one m.c.s. of S, and P is an inevitable consequence (I-consequence) of S if it is a logical consequence of all the m.c.s. of S. The set of W-consequences of a set S it determines (up to logical equivalence) its m.c.s. (This enables us to define a normal form for every set such that any two sets having the same W-consequences have the same normal form.) The W-consequences and I-consequences will not do to define the content of a set S. The first is too broad, may include propositions mutually inconsistent, the second is too narrow. A via media between these concepts is accordingly defined: P is a P-consequence of S, where P is some preference criterion yielding some of the m.c.s. of S as preferred to others, and P is a consequence of all of the P-preferred m.c.s. of S. The bulk of the paper is devoted to discussion of various preference criteria, and also surveys the application of this machinery in diverse contexts - for example, in connection with the processing of mutually inconsistent reports.  相似文献

This paper reports the views and feelings of semen donors at two London donor insemination (Dl) programmes regarding the recipients of Dl and the families created by this method. In particular it reports on: the types of recipients that donors wish to assist; their understanding of the legal position of donors and Di fathers; their views on the'matching' of donors and Dl fathers; their perception of Dl offspring's need or desire for information about the donor; their views on whether parents should tell their offspring about their Dl conception and regarding the secrecy surrounding Dl in general; and what they believe the community thinks about Dl. Overall, the donors perceive Dl families as being normal, and are very supportive of the autonomy and privacy of these families, but they also have concerns about the needs of the offspring. The authors draw attention to the need to take into account the views of donors in forming assisted reproduction policies, and also the need for the interests of the child to be paramount, as they are in the case of adoption.  相似文献

Abstract

How can one subscribe to forms of ethico-religious pacifism and revolutionary communism or anarchism simultaneously, let alone conceive of their adherents as comprising the same transnational social movement? The author explores this conundrum via a playful probing of her own paradoxes related to violence and peace, dualism and non-dualistic thinking, and activist engagement along with more contemplative and quiet reflection. It experiments with expressive auto-ethnography in order to convey what living in and through these paradoxes feels like, and to access and convey other kinds of insights, (self) knowledge, and wisdom, unavailable or inadmissible by more orthodox forms of social science inquiry and writing. It embraces the postmodern relationship among authors, audiences, and texts and valorizes storytelling as deeply pedagogical, constitutive, meaningful, and meaning-making phenomena. The essay weaves together newspaper headlines, apocryphal diary entries, and dream poems into a methodological bricolage drawing from postmodern, poststructural and postcolonial scholars Deleuze and Guattari, Michael Shapiro, Anna Agathangelou, and Ruth Behar among others.  相似文献

Abstract

As a selector, have you ever wondered if the resource you requested was ordered? As an acquisitions staff member, are you struggling with keeping track of your order requests from various channels? As a manager, are you finding it challenging to monitor staff work? CORAL, an open source electronic resource management system, proved to be one solution to these concerns for North Carolina State University (NCSU) Libraries. This article discusses how to manage workflows in CORAL and outlines a NCSU initiative to evolve this tool through collaboration across departments and across the CORAL community.  相似文献

There is increasing evidence that the COVID-19 pandemic has had substantial mental health impacts for adolescents. Yet, few definitive studies have investigated which adolescents were at higher risk of poor mental health and well-being during the pandemic. Data were drawn from the Childhood to Adolescence Transition Study, a prospective cohort study of students in Australia (N = 1211). Prevalence of mental health outcomes (depressive symptoms, anxiety symptoms, self-harm and good subjective well-being) was estimated in school Years 5–12, where Years 11 (2020) and 12 (2021) coincided with the pandemic. The age- and sex-adjusted relative risk of each mental health outcome for each priority group during the pandemic were estimated. During the pandemic, over 50% of study participants reported depressive symptoms, and one quarter reported anxiety symptoms. There was a decrease in good subjective well-being compared with pre-pandemic years, while self-harm prevalence remained similar. History of mental health problems, school disengagement and frequent peer victimisation increased the risk of experiencing mental health problems during the pandemic. Schools play a central role in maintaining the mental health and good subjective well-being of students, and this is particularly important during periods of social disruption, such as the COVID-19 pandemic.  相似文献
