Medicare is a large government health insurance program in the United States that covers about 60 million people. This paper analyzes the effects of Medicare insurance on health for a group of people in urgent need of medical care: people with cancer. We used a regression discontinuity design to assess impacts of near-universal Medicare insurance at age 65 on cancer detection and outcomes, using population-based cancer registries and vital statistics data. Our analysis focused on the three tumor sites for which screening is recommended both before and after age 65: breast, colorectal, and lung cancer. At age 65, cancer detection increased by 72 per 100,000 population among women and 33 per 100,000 population among men; cancer mortality also decreased by nine per 100,000 population for women but did not significantly change for men. In a placebo check, we found no comparable changes at age 65 in Canada. This study provides the first evidence to our knowledge that near-universal access to Medicare at age 65 is associated with improvements in population-level cancer mortality.  相似文献

Living with a nuclear-armed enemy is unattractive, but, strangely, states seldom use their military power to prevent the enemy’s entry into the nuclear club. It is puzzling why preventive strikes against nuclear programs have been quite rare. I address this puzzle by considering the role of conventional retaliation, a subfield of deterrence that so far has received scant attention in the literature. I theorize the concept of conventional retaliation and test its explanatory power. First, I explore all historical cases where states struck another state’s nuclear installations and find none occurring when the proliferator threatened conventional retaliation. Second, I explore two cases where a strike was most likely, but the would-be attacker balked and find smoking-gun evidence that the threat of conventional retaliation restrained the would-be attacker. This evidence supports my claim that the threat of conventional retaliation is sufficient to deter a preventive strike against emerging nuclear states.  相似文献

Building on the transactionalist paradigm in the tradition of Karl W. Deutsch as well as on Arndt Sorge’s theory of tiered social spaces, this study examines why everyday actions and attitudes are more centered on Europe (i.?e. “Europeanized”) in some EU member states than in others. Analyzing a variety of survey data on the EU-27 countries with partial correlation models, it is shown that the macro-level determinants of Europeanization differ between actions and attitudes. While actions are more Europe-centered in small and affluent countries, attitudes are more Europe-centered in post-communist states as well as in countries that are located in the geographical center of the EU and that do not have a protestant religious tradition. Contrary to transactionalist theory, the Europeanization of actions does not coincide with the Europeanization of attitudes: “doing Europe” and “feeling Europe” do not go hand in hand.  相似文献

This article analyses the impact of the euro crisis on national parliaments and examines their response to the deepening of EU fiscal integration and the correspondent limitation of their budgetary autonomy. It argues that the sovereign debt crisis has provoked the emergence of new channels of parliamentary involvement in EU economic governance. National parliaments have acquired various rights of approval in the European Semester, strengthened the accountability of national governments, reinforced their scrutiny over budgeting, improved their access to information, and created domestic and supranational avenues for deliberation and political contestation of European integration. In these respects, they have undergone further Europeanisation. While these reforms do not outweigh the centralisation of EU powers, they represent an embryonic step in the parliamentary adaptation to the nascent EU fiscal regime. Yet they are unlikely substantially to influence EMU policy‐making processes, because of the democratic disconnect inherent in the EU's multilevel constitution.  相似文献

To investigate the dual-target rapid serial visual presentation (dtRSVP) task as a measure of deviant sexual interest (i.e. a sexual interest in children), we administered a dtRSVP with gender- and age-specific pictorial stimuli to child sex offenders (n = 69), other sex offenders (n = 43), non-sex offenders (n = 14), and community controls (n = 88). We hypothesized that (1) stimuli belonging to the preferred gender and age group presented as targets (both T1 and the subsequent T2) in the serial sequence would be more accurately detected than non-preferred stimuli and that (2) this increased detection would reduce the detection of targets later in the serial sequence (T2) due to an attentional blink. Our findings supported hypothesis 1 and partly supported hypothesis 2. Although we found group differences, individual indices based on detection rates did not allow for individual-level diagnostic categorization of participants.  相似文献

Drawing from group theories of race-related attitudes and electoral politics, we develop and test how anxiety influences the relative weight of prejudice as a determinant of individuals’ support for racial policies. We hypothesize that prejudice will more strongly influence the racial policy preferences of people who are feeling anxious than it will for people who are not. Using an experimental design we manipulate subjects’ levels of threat and find significant treatment effects, as hypothesized. We find that individuals’ racial policy attitudes are partially conditional on their affective states: individuals who feel anxious report less support for racial policies than those individuals who do not feel anxious, even when this threat is stimulated by non-racial content. More broadly, we conclude that affect is central to a better understanding of individuals’ political attitudes and behaviors.  相似文献
