Using data from the Michigan Panel Study of Income Dynamics, this article estimates the impact of the Earned Income Tax Credit (EITC) on economic risk. Risk is measured through the variance of full income (income holding labor supply constant). The results show that the EITC significantly reduces economic risk, but its effects are weaker dollar for dollar than traditional means-tested programs like Food Stamps. The difference is not statistically significant, however. Moreover, for many middle-class people, the risk-reduction benefits of the EITC exceed the tax burden it imposes. This is less true of means-tested transfers. These results are significant for the politics of antipoverty policy. They show that a real-world antipoverty program can generate enough middle-class economic security to build for itself a solid base of political support. 相似文献

Schools across the country are ending the practice of grouping students based on ability, in part, because of research indicating that tracking hurts low-ability students without helping students of other ability levels. Using a nationally representative survey conducted by the National Center for Education Statistics, (NCES) we reexamine the impact of tracking on high school student achievement through the estimation of a standard education production function. This approach allows us to control for the possibility that track is correlated with factors such as class size and teacher education. In addition, we address the possibility that there are unobserved student or school characteristics that affect both achievement and track placement. Our results indicate that abolishing tracking in America's schools would have a large positive impact on achievement for students currently in the lower tracks, but that this increase in achievement would come at the expense of students in upper-track classes. 相似文献

The treatment processes associated with reduced suicidal ideation have received little research attention. This study evaluates the influence on suicidal ideation of theory-based intrapsychic processes: maladaptive cognition and defensive style. Thirty-three community mental health patients completed questionnaires at two time points. Decreases in automatic thoughts were a strong correlate of decreased suicidal ideation, and decreases in immature defenses were a moderate strength correlate. These relationships remained significant even when controlling for initial level of depression. The theorized mechanisms of cognitive-behavioral and psychodynamic therapy had the expected effects on suicidal ideation. The strong association of decreased maladaptive cognitions with decreased suicidal ideation supports further development of cognitive-behavioral suicide interventions and clinical use of cognitive interventions. Psychodynamic processes in suicidal ideation and behavior warrant further exploration. 相似文献

Prime Minister Koizumi’s six consecutive annual visits to Yasukuni shrine played a key role in initiating a new phase of domestic
citizen political mobilization not seen since the early 1970s. This paper is based on field research during the Koizumi years
(2001–2006) centering on domestic groups that conduct activities in “protection” of or “opposition” to Yasukuni shrine. As
a study of street-based politics, this paper seeks to uncover the processes, strategies, and outcomes of citizen responses
to elite political action at Yasukuni Shrine as well as explore meaning of their actions within the context of Japan’s democratic
polity.

His doctoral dissertation, entitled ‘Democracy and Yasukuni: Citizen Reaction to political action at Yasukuni Shrine, 2001–2006’ has served as the basis for conference presentations on Yasukuni and its attendant controversies. 相似文献

Microbial communities have potential evidential utility for forensic applications. However, bioinformatic analysis of high-throughput sequencing data varies widely among laboratories. These differences can potentially affect microbial community composition and downstream analyses. To illustrate the importance of standardizing methodology, we compared analyses of postmortem microbiome samples using several bioinformatic pipelines, varying minimum library size or minimum number of sequences per sample, and sample size. Using the same input sequence data, we found that three open-source bioinformatic pipelines, MG-RAST, mothur, and QIIME2, had significant differences in relative abundance, alpha-diversity, and beta-diversity, despite the same input data. Increasing minimum library size and sample size increased the number of low-abundant and infrequent taxa detected. Our results show that bioinformatic pipeline and parameter choice affect results in important ways. Given the growing potential application of forensic microbiology to the criminal justice system, continued research on standardizing computational methodology will be important for downstream applications. 相似文献
