地方创新性立法是推进地方治理法治化的重要手段,鼓励地方立法创新是完善我国立法体制的应有之义。为实现地方创新性立法的规范化,应明确地方性事务的判断标准,引入重大事项请示报告制度,加强立法决策量化论证。     

RACIAL–ETHNIC INTOLERANCE AND SUPPORT FOR CAPITAL PUNISHMENT: A CROSS-NATIONAL COMPARISON*

This article tests cross-nationally the minority group threat thesis that public sentiments toward repressive crime-control policies reflect conflicted racial and ethnic relations. Using multiple data sets representing France, Belgium, the Netherlands, East and West Germany, Italy, Luxembourg, Denmark, Great Britain, Greece, Spain, Finland, Sweden, Austria, Canada, Ireland, and Portugal, we examine whether racial and ethnic intolerance—animus, resentments, or negative sentiments toward minorities—predicts greater support for the death penalty. Our results reveal that the respondents were significantly more likely to express support for capital punishment if they were racially or ethnically intolerant while controlling for other covariates of public opinion. These findings indicate that the link between support for capital punishment and racial and ethnic animus may occur universally in countries with conflicted racial and ethnic relations.     

鸡传染性支气管炎病毒陕西分离株M蛋白基因的变异及其B细胞表位稳定性

以陕西8株鸡传染性支气管炎病毒(AIBV)分离株M蛋白的基因序列为基础,应用DNAStar软件中的MegAlign模块对其进行了同源性分析;用Kyte-Doolittle方法、Jameson-Wolf方法、Karplus-Schulz方法、Plot-Emini方法和Garnier-Robson方法综合预测了其中4株代表毒株的M蛋白B细胞抗原表位和二级结构。结果,8株AIBV的M蛋白主要在10~40 aa和90~175 aa处存在无规律的点突变,与参考毒株H52、M41、SAIB20、LX和Gray的M蛋白的核苷酸序列和预测的氨基酸序列的同源性分别介于87.4%~99.5%和96.3%~99.5%;分离株间的核苷酸序列和预测的氨基酸序列同源性分别介于91.8%~99.8%和95.4%~100%。4株代表株的M蛋白B细胞优势抗原表位都在159~164 aa和181~193 aa肽段区(这2个区域都包含了无规则卷曲和β-转角结构)或其附近。结果表明,AIBV分离株的M蛋白基因相对保守,只存在无规律的点突变,该变异对AIBV M蛋白B细胞表位的稳定性无影响。     

COMMUNITY ACCOUNTABILITY,MINORITY THREAT,AND POLICE BRUTALITY: AN EXAMINATION OF CIVIL RIGHTS CRIMINAL COMPLAINTS*

A growing body of evidence shows that minorities are disproportionately the targets of police brutality, but important theoretical questions about the causes of that inequity remain unanswered. One promising line of research involves structural‐level analyses of the incidence of police brutality complaints; however, existing studies do not incorporate variables from alternative theoretical explanations. Drawing on the community accountability hypothesis and the threat hypothesis, we tested the predictions of two prominent structural‐level explanations of police brutality in a study of civil rights criminal complaints. The study included cities of 150,000+ population (n = 114). The findings reveal that two community accountability variables—ratio percent Hispanic citizens to percent Hispanic police officers and the presence of citizen review—were related positively to police brutality complaints, partially supporting that perspective. Two threat hypothesis measures of threatening people—percent black and percent Hispanic (in the Southwest)—were related positively to complaints, as predicted. The relative degree of support for the two hypotheses is assessed.

Gender Differences in Self-Perceptions and Academic Outcomes: A Study of African American High School Students

There is increasing divergence in the academic outcomes of African American males and females. By most accounts, males are falling behind their female peers educationally as African American females are graduating from high schools at higher rates and are going on to college and graduate school in greater numbers. Some have suggested that school completion and performance is associated with how students feel about themselves. The purpose of this study was to explore gender differences in the relationship between self-perceptions and 2 academic outcomes among a sample of 243 African American high school sophomores. The results suggest that, overall, females are more favorably oriented toward high school completion. Both male and female students with more positive self-perceptions have stronger intentions to complete the current year of high school. Higher grade point averages were more strongly associated with greater self-efficacy for females than for males. Given these findings, increased attention to educational programming, societal messages, and future research is warranted.     

Black Cities/White Cities: Evaluating the Police

It is well known that African Americans and whites hold different views of the police, but nearly all of the previous research has been conducted in majority white settings. This research examines the relationship between race and evaluations of the police in majority black versus majority white contexts. Social dominance theory and the research on racial threat predict that when the racial majority changes, the relationship between race and attitudes toward police will change. We find that, in majority black contexts, the traditional relationship between being black and having negative evaluations of the police disappears, and it disappears because whites' evaluations of the police become more negative. Black evaluations of the police are relatively consistent across racial contexts. Also, white racial attitudes affect police evaluations in majority black contexts, but not in white contexts, while African American racial attitudes are inconsequential in both contexts. Furthermore, if a white citizen is victimized by crime in a black city, it has greater ramifications for evaluations of the police than if the victimization had occurred in a white city. All of this suggests that whites' views of the police may be more racialized than the views of African Americans.     

Race and the City: Neighborhood Context and the Development of Generalized Trust

Previous research has indicated that socio-economic and racial characteristics of an individual's environment influence not only group consciousness and solidarity, but also affect his or her views toward minority or majority groups. Missing from this research is a consideration of how context, social interaction, and interracial experiences combine to shape more general psychological orientations such as generalized trust. In this study we address this gap in the literature by conducting a neighborhood-level analysis that examines how race, racial attitudes, social interactions, and residential patterns affect generalized trust. Our findings suggest not only that the neighborhood context plays an important role in shaping civic orientations, but that the diversity of interaction settings is a key condition for the development of generalized trust.     

Police professionalism and cynicism reconsidered: An assessment of measurement issues

A hierarchical logistic model is used to analyze data on Three Strikes-eligible offenders in California and the counties in which they are sentenced. The analysis finds that discretion is widely exercised by elected prosecutors and judges in the administration of Three Strikes. Discretion functions as a “safety valve” and preserves some sentencing proportionality, but may also allow political concerns to influence sentencing decisions. A more conservative political environment is strongly associated with stricter application of the law. Consistent with racial threat theory, eligible felons are more likely to receive Three Strikes sentences in counties with larger Latino populations. However, the size of the black population has no significant effect. Higher unemployment rates are associated with more stringent application of the law. Prosecutorial and judicial discretion benefits offenders unequally. Controlling for legally relevant factors, black offenders are more likely to receive Three Strikes sentences, while younger ones are less likely.
