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

基于2001—2012数据和显示性对称比较优势指数(RSCA),运用散点图和非参数核密度估计统计方法,实证分析两岸农产品贸易比较优势的动态变化。结果显示:大陆农产品的比较优势在恶化,农产品出口贸易越来越集中在少数具有比较优势的产品上;台湾农产品基本上不具有比较优势,但是2007年以来比较优势有改善趋势;在双边贸易中,大陆对台湾出口农产品的比较优势总体上呈上升趋势,具有比较优势的产品在增加,而台湾对大陆农产品贸易则不具有比较优势,但是在统计期间出口专业化程度明显下降,比较优势趋于改善。 相似文献

Fatal Fentanyl Patch Misuse in a Hospitalized Patient with a Postmortem Increase in Fentanyl Blood Concentration 下载免费PDF全文

Opioid‐related mortality happens, even in healthcare settings. We describe serial postmortem fentanyl blood concentrations in a hospital inpatient who fatally abused transdermal fentanyl. This is a single‐patient case report. A 42‐year‐old man with lymphoma was started on transdermal fentanyl therapy while hospitalized for chronic abdominal pain. The patient was last seen awake 1.3 h prior to being found apneic and cyanotic. During the resuscitation attempt, a small square‐shaped film was removed from the patient's oropharynx. Femoral blood was collected 0.5 and 2 h postmortem, and the measured fentanyl concentration increased from 1.6 to 14 ng/mL. Study limitations include potential laboratory or collection errors and missing data. (i) Providers must be vigilant for signs of fentanyl patch abuse. (ii) Postmortem blood concentrations are not static postmortem, likely secondary to decreasing pH, increased aqueous solubility, and tissue redistribution, and are therefore unlikely to accurately represent antemortem blood concentrations. 相似文献

Human security has increasingly shifted attention to the individual, while the state has become guarantor (or violator) of security given its role in governing the domestic environment. This article examines how variations in regime forms influence security, pointing to the importance of political security in the wider human security framework. To illustrate, the article examines the nature of political security in Central America, a region with weakly democratized states and histories of political violence. The findings suggest a link between democracy and human security that is mediated by state capacity and the ability to control non-state violence against individuals. 相似文献
