There is growing interest in the use of unconditional cash transfers as a means to alleviate poverty, yet little is known about the effects of such transfers in the U.S. This paper reports on the results of a randomized controlled study of a one-time $1,000 unconditional cash transfer in May 2020 to families with low incomes in 12 U.S. states. The families were receiving, or had recently received, Supplemental Nutrition Assistance Program benefits. We examine the impact of the cash transfer on five pre-registered outcomes (material hardship, mental health, parenting, child behavior, partner relationships) and several secondary outcomes (hardship avoidance, consumption, employment, benefit use). We find no statistically significant effects (powered to detect effects of 0.09 standard deviations) of the cash transfer on any outcomes for the full sample. In pre-specified exploratory analyses, we find significant reductions in material hardship (-0.17 standard deviations) among families with less than $500 of earnings in the previous month, roughly the bottom 50 percent of monthly earnings for the study sample. 相似文献

This article examines the emergence of Aleksandr Dugin as the leader of the Eurasian Movement and later Party in Russia. For much of the 1990s Dugin was a prominent intellectual among the Russian nationalist‐communist opposition, moving from the position of ideologue of a fringe political party ‐ Edvard Limonov's National Bolsheviks — to advisor to the communist speaker of the State Duma, Gennadiy Seleznev. Dugin's ideology combined an anti‐Western interpretation of geopolitics with mysticism, Aryanism, conspirology, authoritarian statism and Eurasianism. Dugin's expanding set of Internet sites became an ideological empire of a virtual society. In 1999, in the aftermath of the NATO intervention in Yugoslavia, Dugin saw an opportunity to move from the marginal opposition to the ideologue of the post‐Yeltsin president. In this capacity, Dugin and his Eurasian Movement emerged as prominent supporters of Vladimir Putin, whom Dugin identified as the embodiment of the ‘Eurasian capitalist’ model of statist development. Dugin developed a close working relationship with Gleb Pavlovsky, a spin doctor for Putin's Kremlin. In the aftermath of 11 September and Putin's move towards supporting the United States in the war on terrorism, Dugin has continued his nominal support for the president, even as he has criticized his pro‐Western policies as anti‐Eurasian and a threat to Russian interests. 相似文献

The authors report on West European trends in follow-up arrangements of national quality assurance procedures. They argue
that external quality assurance ought to adopt a broader conception of quality than is now often the case. Next, the general
public ought to have a guarantee that external quality assurance is valid (through meta-evaluation) and has consequences (through
follow-up arrangements). Follow-up currently is not well developed in many European countries in a formal sense, but is receiving
more attention as external quality assurance is maturing. Finally, the authors link national quality assurance to the European
dimension; an international network could fulfil important functions in making quality assurance transparent and credible
across Europe.

Identification of fentanyl derivatives 总被引:1,自引:0,他引:1
An interpretative approach to the identification of fentanyl homologs and analogs is presented. The techniques employed are liquid/liquid extractions; capillary gas chromatography; and infrared, mass, and nuclear magnetic resonance spectral characterization. Spectral data are presented for eight fentanyl derivatives of clandestine origin. 相似文献

Extant work on status attribution has largely focused on major powers or state capabilities as key explanatory factors driving these social processes and suggests that status considerations increase conflicts between states. We argue for a more comprehensive approach to status attribution that considers international norms as another major factor that is weighed in the attribution process. We contend that states (policymakers) evaluate one another not only on the basis of economic and military capabilities but also on the extent to which there is behavioral conformance with normative expectations and reward one another dependent upon whether these expectations are met. However, this attribution of status is dependent upon the level of contestation pertaining to that norm. Using a data set that assesses consistency with six different norms (resource transference, multilateralism, economic liberalism, democratic governance, respect for human rights, and peaceful dispute resolution), we find that status attribution is associated with norm-consistent behavior but only when these norms are uncontested at the global level. 相似文献
