Though political scientists generally understand the origins of native‐born reactions to foreigners, less is known about how anti‐immigrant contexts trigger a political response within immigrant groups. I address this question by studying the connection between xenophobic rhetoric and Latino politics. I claim that xenophobic rhetoric raises the salience of ethnic identity and impugns its worth. This identity threat leads high‐identifying group members to engage in political efforts that assert their group's positive value, whereas low identifiers shun political opportunities to bolster their group's devaluation. I test these claims with an experiment embedded in a nationally representative opinion survey of Latino adults. In light of xenophobic rhetoric, I find that relative to low identifiers, high‐identifying Latinos become less politically trusting, more ethnocentric, and increasingly supportive of policies that emphasize ingroup pride. These results clarify xenophobic rhetoric's role in amplifying the influence of ethnic identity on immigrant politics. 相似文献

According to judicial precedents, administrators informed by their expertise can speak on issues of public concern under First Amendment protections. In one sense, they could dissent by working against their employers in an attempt to direct issues of public concern through an educational function. The power to act like a statesman in raising such issues allows administrators to lead from behind and in front, as long as certain judicial thresholds are met. However, the U.S. Supreme Court recently moved to tighten the scope of such activity. This article assesses how an ethic of dissent has been translated into a constitutional perspective that at first was moderately constrained and later became very restricted. While the move to limit an ethic of dissent provides necessary constraints, it also may have weakened administrators’ ability to perform necessary statesmanship acts rooted in guerrilla government to achieve the common good. 相似文献

Performance‐Related Pay and the Crowding Out of Motivation in the Public Sector: A Randomized Field Experiment

This article advances our understanding of the effects of monetary rewards on public employee performance and of the contingencies that may moderate these effects. In a randomized control‐group experiment with nurses working at a local health authority in Italy, performance‐related pay (PRP) had a larger effect on task performance when the rewards were kept secret than when they were disclosed. The negative interaction between PRP and visibility was stronger among participants who were exposed to direct contact with a beneficiary of their efforts, which heightened their perception of making a positive difference in other people's lives. These results are consistent with theoretical predictions that monetary incentives for activities with a prosocial impact may crowd out employee image motivation. There were no crowding‐out effects when a symbolic reward was substituted for the monetary incentive. 相似文献

In February 2005, Illinois became the first U.S. state to grant home‐based child care providers (HBCPs) the right to form a labor union in order to bargain collectively with the state government. This policy inspired similar efforts across the country and represents a potentially important direction for child care policy. To date, the implications of labor unions for the cost, type, and availability of subsidized child care have not been evaluated empirically. In this study, we examine the impact of granting Illinois HBCPs the right to form a labor union on (a) the type of child care (licensed vs. license‐exempt/home‐based vs. center‐based) used by subsidy‐receiving Illinois infants and toddlers; (b) the per‐child cost of subsidized child care for infants and toddlers; and (c) the percentage of Illinois infants and toddlers who use child care subsidies. To conduct these analyses, we combine data from the Current Population Survey with Child Care and Development Fund administrative records on U.S. infants and toddlers whose families received child care subsidies during the period from 2002 to 2008. We use both a traditional difference‐in‐differences as well as a comparative case study with a “synthetic” control group approach. The synthetic control group approach improves on traditional comparative case studies by providing a transparent, empirical approach for constructing the counterfactual, documenting comparison units’ contribution to the synthetically created control group and detailing the degree to which the synthetic control group is, or is not, similar to the treated unit on preintervention measures of the outcome as well as on other selected characteristics. We find that subsidy‐receiving Illinois infants and toddlers spent an average of between 6.4 and 7 percentage points more hours in licensed care settings, as compared to license‐exempt settings, in the three years following child care unionization. We also find that between 0.7 and 1.1 percentage points fewer Illinois infants and toddlers used child care subsidies following unionization. 相似文献

AbstractThis article takes an unlikely approach to thinking about intersectionality theory. Exploring key concepts from the writings of Hannah Arendt, such as plurality, conscious pariah, and statelessness, alongside her embodied interrogation of anti-Semitism and the Jewish Question, it suggests a way to transgress the ordinary boundaries of the concepts of queer, international, and feminist and, conversely, to unbound the ordinary ways Arendt’s theories have been interpreted as less relevant, if not antithetical to, feminist, intersectional, and queer theories and politics. 相似文献

Sexual offenses represent an alarming proportion of crimes committed yearly. To address these concerns, several states, including South Carolina (SC), have enacted laws requiring sexually violent predators (SVPs) to be civilly committed to treatment. To date, no published study has examined sexual offenders recommended for treatment in SC. This study used a specially designed statewide database (SC-SVP research database) to determine which offender and offense characteristics were associated with increased likelihood of being recommended for civil commitment. Factors correlated with being more likely to be recommended included: being of a younger age at time of evaluation, prior sex convictions, having related and unrelated victims, a higher number of victims, frequent substance use, and a history of suicide attempts. Prior sex convictions, having both related and non-related victims, and a higher total number of victims align with characteristics associated with sexual recidivism. Frequent substance abuse and a history of suicide attempts do not mirror previous findings regarding sexual recidivism. These findings present new information regarding the civil commitment process of offenders being committed to the SC-SVP treatment program, characterize types of offenders committed to SC-SVP treatment program, and provide a foundation for using a computerized database in conducting sex offender research. 相似文献
