Cultural studies professed ‘radical contextualism’ imbues the project with a particular orientation toward ‘the present,’ a consideration of ‘the current moment’ as a configuration of forces shaping possibilities for politically engaged practice and affording concrete potentials for telling better stories. This essay elaborates these claims by way of tribute to Lawrence Grossberg. It is neither retrospective nor prospective. Instead – and in a manner more befitting a figure who continues to champion the political-intellectual practice of cultural studies here and now, in the present – this essay reflects on the author’s experiences learning with and from Grossberg in order to explore the the temporality of the cultural studies project. 相似文献

Predicting catastrophes involves heavy‐tailed distributions with no mean, eluding proactive policy as expected cost‐benefit analysis fails. We study US government counterterrorism policy, given heightened risk of terrorism. But terrorism also involves human behavior. We synthesize the behavioral and statistical aspects in an adversary‐defender game. Calibration to extensive data shows that where a Weibull distribution is the best predictor, US counterterrorism policy is rational (and optimal). Here, we estimate the adversary's unobserved variables, e.g., difficulty of an attack. We also find cases where the best predictor is a Generalized‐Pareto with no finite mean and rational policy fails. Here, we offer “work‐arounds”. (JEL H56, D81, C46) 相似文献

This study analyzes the stability of cohabiting and marital unions following a first birth. But unlike previous research, it compares the subsequent trajectories of unions that began with a pregnancy to those in which conceptions came after coresidence. The U.S. data from the 2006–2010 and 2011–2013 cross-sectional files of the National Survey of Family Growth indicate that roughly 1-in-5 first births were associated with rapid transitions from conception into either cohabitation or marriage. Moving in together following a pregnancy—especially an unintended one—is unlikely to lead to marital success or union stability. Compared with marital unions, dissolution rates following birth were particularly high for couples who entered a cohabiting union following conception. Only a small minority of these couples married (i.e., less than one-third), and these marriages experienced high dissolution rates. The results also suggest that the most committed cohabiting couples got married after finding themselves pregnant, leaving behind the most dissolution-prone cohabiting couples. The American family system is being transformed by newly emerging patterns of fertility among cohabiting couples. 相似文献

There is a significant amount of research that analyzes the consequences of repression on social movement mobilization. Yet most studies do not examine the strategic agency of protesters, who can avoid, minimize, or transform punitive sanctions. In this article, I call for an agency-centered approach that highlights the iterative dynamics between protesters and agents of repression, emphasizing that the consequences of repression are largely shaped by activists' responses. Reviewing the literature on this topic, I summarize common methods of repression used by both the state and private citizens—such as information gathering, planting provocateurs, legal harassment, and direct violence. I also discuss movement counter-methods for muting the impact of repression, which include tactical shifts, decentralized organizational structures, and obstructing surveillance technologies, among others. While researchers have documented typical methods of social control, we must also capture protesters' tool kit of strategic responses that enable movements to persist during periods of repression. 相似文献

The Personal Responsibility Work Opportunity Reconciliation Act, Pub.L. 104-193 (PRWORA) was passed creating the Temporary Assistance to Needy Families (TANF) program. Since the passage of PRWORA, many families were able to leave the welfare rolls while those remaining on welfare were likely composed of families facing barriers to leaving, such as caring for children with disabilities. This project addresses the gaps in knowledge regarding low-income families caring for children with disabilities by conducting qualitative research investigating the resources used by these families to find and keep employment and child care. The study used a sample from a research project entitled ‘Rural Families Speak’ and examined the data of 26 families caring for children with disabilities. Analysis resulted in policy recommendations for increasing the efficacy of the programs designed to help these families. 相似文献

This paper defines a general equilibrium model with exchange and club formation. Agents trade multiple private goods widely in the market, can belong to several clubs, and care about the characteristics of the other members of their clubs. The space of agents is a continuum, but clubs are finite. It is shown that (i) competitive equilibria exist, and (ii) the core coincides with the set of equilibrium states. The central subtlety is in modeling club memberships and expressing the notion that membership choices are consistent across the population. 相似文献

The focus of this edition of “The Balance Point” is text and data mining (TDM). The column editor invited Professor Michelle Alexopoulos from the University of Toronto to coauthor the column. Alexopoulos has completed several major TDM projects and gained considerable knowledge and expertise in the field. The authors conclude that TDM is an important research tool for most disciplines and is growing in importance. As such, libraries and librarians will need to develop new services and partnerships to meet the changing research needs of their constituencies. 相似文献

This paper shows that the semiparametric efficiency bound for a parameter identified by an unconditional moment restriction with data missing at random (MAR) coincides with that of a particular augmented moment condition problem. The augmented system consists of the inverse probability weighted (IPW) original moment restriction and an additional conditional moment restriction which exhausts all other implications of the MAR assumption. The paper also investigates the value of additional semiparametric restrictions on the conditional expectation function (CEF) of the original moment function given always observed covariates. In the program evaluation context, for example, such restrictions are implied by semiparametric models for the potential outcome CEFs given baseline covariates. The efficiency bound associated with this model is shown to also coincide with that of a particular moment condition problem. Some implications of these results for estimation are briefly discussed. 相似文献

This paper proposes a new method for identifying social interactions using conditional variance restrictions. The method provides a consistent estimate of the social multiplier when social interactions take the “linear‐in‐means” form (Manski (1993)). When social interactions are not of the linear‐in‐means form, the estimator, under certain conditions, continues to form the basis of a consistent test of the no social interactions null with correct large sample size. The methods are illustrated using data from the Tennessee class size reduction experiment Project STAR. The application suggests that differences in peer group quality were an important source of individual‐level variation in the academic achievement of Project STAR kindergarten students. 相似文献
