The recent debate concerning the efficiency of sharecropping contracts yields a number of testable hypotheses, four of which can be examined in the light of some primary data for a group of sharecroppers in northeast Bihar. The salient feature of the empirical analysis is the comparison of the resource allocation patterns on owned and rented land cultivated by the same farmer, which provides a more powerful test of inefficiency than those advocated previously. Broadly speaking, the findings support the ‘Marshallian’ position that such contracts do involve inefficiency—in the Bihar context, at least.  相似文献

Abstract

Bringing together the work of Barad and Deleuze, this article develops the concept of the living present as a frame for an emerging feminist temporality. Within feminist and queer theories, there has been much discussion of the value of non-chronological time in opening up a transformative and unknown future. The author expands on this arena by discussing not only the future, but also the echoes, resonances and traces of the past—a past whose material effects continue to act as living, changing forces on the present and the future. Described as the present of retention and expectation, the living present is never a static ‘now’, but always a stretching between past and future as it contracts all past experiences and expects those yet to come. As it builds on the work of Grosz, Colebrook and others, the living present encourages non-linear, open-ended readings of past events, and therefore represents a new lens through which to approach documented and assumed histories. By opening up collaborative lines of flight between new materialism, Deleuze and feminism, the thick time of the living present reveals a past of forceful, intra-active materialities. It is a realm of possibility to which one is accountable, but not bound.  相似文献

The impact of the cardinal relationships amongpecuniary payoffs, and of social history and reputation, on thechoice of strategies in four one-shot Prisoner's Dilemma games isexperimentally examined. The results suggest that normalized payoffvalues linked to ``fear'' and ``greed'' are important as predictorsof behavior in the PD games. Success in coordinating on the payoffdominant equilibrium in previous plays of coordination games alsoincreases the probability of cooperative play in the PD games. Theeffect of past play is strongest when individuals are matchedrepeatedly with the same person in previous play, as contrasted tobeing matched randomly with another player.  相似文献

Lesbian, gay, and bisexual youth are at heightened risk for bullying and other forms of in-school victimization. Anti-bullying laws are a potential policy mechanism for addressing this issue, yet there has been little investigation of the impact of such policies for this population using generalizable samples or quasi-experimental designs. The current study explores whether the presence of state anti-bullying laws predicts lower likelihood of bullying victimization, fear-based absenteeism, in-school threats or injury with a weapon, and suicidality for lesbian, gay, bisexual, and questioning high school students in the United States. Based on Youth Risk Behavior Survey data across 22 states from 2005–2015, coupled with data about the presence of general and enumerated anti-bullying laws that include sexual orientation as a protected class, this study analyzes this topic using a quasi-experimental design (linear difference-in-difference models). The results indicate that lesbian, gay, bisexual, and questioning youth (particularly boys aged 15 or younger) experienced less bullying victimization in states with general or enumerated anti-bullying laws. There was modest evidence of a reduction in fear-based absenteeism among boys in states with such laws. However, there was little evidence of a relationship between such policies and in-school threats or injuries or suicidality. Further, lesbian, bisexual, and questioning girls’ likelihood of victimization, absenteeism, or suicidality was generally not related to the presence of anti-bullying laws. The results suggest that general and enumerated anti-bullying laws may help reduce bullying victimization for gay, bisexual, and questioning boys.  相似文献

The Asian economic crisis of 1997 highlighted the inherent instability of the new worldwide economic order being created by highly mobile capital, and also its destabilizing social and political effects, especially in the transitional societies which had proved so hospitable to the champions of globalization and to proffered capital inputs. Whether these societies are destined to be subsumed and captured by globalization processes, or whether they and their citizens have any possibility of capturing some genuine benefits from advancing globalization, may rest on whether these transitional states and societies can assert, or at least influence, the terms of their engagement with those processes. This will not be possible, however, if people, societies and states capitulate in advance to the forces and processes of globalization as irresistible. This issue is explored through the grounded investigation of four key questions: do globalization processes serve any ends beyond themselves? How might one grasp the best, and make the most, of globalization? Is the logic of the market immutable and inflexible transculturally, or is it amenable to varying forms of cultural inflection and political supervision? Can what globalization delivers be drawn upon selectively, or is it instead a 'package-deal'?  相似文献

It is argued that past approaches to the research of housing policy and housing organizations are now inadequate and unable to provide a clear explanation of modernization and change. The modernization of social housing is associated with changing core organizational competencies and the movement towards a variety of partnership approaches. In response we develop a tripartite theoretical framework based around new institutional economics, strategic management and institutional theory. An exploratory review of the evidence at a sectoral level (examining social housing as a field, regulation and the profession) and the organizational level (focusing upon changing organization behaviour) is used to illustrate the legitimacy of this approach. In conclusion a research agenda is outlined.  相似文献

A study was conducted on decomposition and insect succession in the Prairie Ecozone of Saskatchewan in the year 2000. Eighteen domestic pig carcasses (42-79 kg) were employed as human models for applications to future homicide investigations in this region. Two major variables were considered including the effect of season and habitat (sun versus shade). Research was conducted over 25 weeks, spanning three seasons: spring, summer and fall. Ambient temperature, internal carcass temperature, faunistic succession over time, and the rate of decay were all compared for each experimental variable. Results indicated that habitat was only a factor in the decompositional rate of carrion in the spring season. The ambient temperature was the chief factor determining the seasonal variations in decay rate. Maximum internal carcass temperatures always coincided with the presence of 3rd instar larvae. Patterns of insect succession occurred in a predictable sequence that varied across different habitats and seasons and was unique compared to previously published studies. Carcasses placed in spring and fall attracted a more diverse assemblage of insects than summer-placed carrion. Sun-exposed carrion also had greater variation in fauna than shaded carrion in spring and fall. Members of Silphidae were the first coleopteran colonizers in all habitats and seasons. This paper also marks the first record for Cochliomyia macellaria (Fabricius) in Saskatchewan.  相似文献

American courts use social science research in three distinct ways: to make law, to determine facts, and to provide context. In this article, we review and critique the approaches that courts have traditionally taken to dealing with each form of social research. We also summarize and integrate a body of work offering a different perspective that treats law-making research associal authority, fact-finding research associal fact, and context-providing research associal framework. We end by proposing a coherent sequence of steps that courts should take when confronted with an empirical question about human behavior.This article was prepared under the auspices of the Task Force on Judicial and Regulatory Decisionmaking of the Carnegie Commission on Science, Technology, and Government. The views expressed are those of the authors rather than of the Task Force or the Commission. We are grateful to David Z. Beckler, Associate Director, for his comments.
