The aim of the present study was to examine a model positing that association with deviant peers mediates the relation between adolescent perceived parenting behaviors (maternal monitoring and involvement), the interaction of these parenting behaviors, and delinquency in a sample of 135 urban African American adolescents (13–19 years of age). Regression analyses revealed a monitoring by involvement interaction among African American females, suggesting that maternal monitoring may effectively reduce delinquency among African American female adolescents, and that this reduction may be enhanced by increased maternal involvement. Among African American males, only the relation between association with deviant peers and delinquency was supported, suggesting that maternal parenting behaviors may, in isolation, be insufficient in the prevention of delinquent behaviors in African American male adolescents. The results suggest that the pathways from parenting to association with deviant peers and delinquency may differ in males and females, and the salience of certain parenting behaviors may differ across gender. This article is based on research that was submitted by the first author in partial fulfillment of the requirements of the master’s degree in psychology at the University at Albany, State University of New York.

Sweden's new multipillar pension system includes a system of mandatory fully funded individual accounts. The Swedish system offers contributors more than 600 fund options from a variety of private-sector fund managers. However, in the most recent rounds of fund choice, more than 90 percent of new labor market entrants have not made an active choice of funds and thus have ended up in a government-sponsored default fund. The Swedish system offers a number of lessons about implementing a mandatory individual account tier. Centralized administration keeps administrative costs down but requires considerable lead time. A very large number of fund options are likely to be offered unless strong entry barriers are in place. Engaging new labor market entrants in fund choice is likely to be difficult. A significant percentage of those making an active fund choice may choose funds that are very specialized and risky. Finally, special care must be devoted to designing a default fund and continual consumer communication.  相似文献

Results obtained from three commercial immunoassay kits, Abuscreen, TDx, and EMIT, commonly used for the initial test of urine cannabinoids (and metabolites) were correlated with the 11-nor-delta 9-tetrahydrocannabinol-9-carboxylic acid (9-THC-COOH) concentration as determined by GC/MS. Correlation coefficients obtained based on 26 (out of 1359 total sample population) highly relevant samples, are 0.601 and 0.438 for Abuscreen and TDx. Correlation coefficients obtained from a parallel study on a different set of 47 (out of 5070 total sample population) highly relevant specimens are 0.658 and 0.575 for Abuscreen and Emit. The immunoassay concentration levels, that correspond to the commonly used 15 ng/ml GC/MS cutoff value for 9-THC-COOH, as calculated from the regression equations are 82 ng/ml and 75 ng/ml for TDx and EMIT and 120 ng/ml and 72 ng/ml for Abuscreen manufactured at two different time periods. The difference of these calculated corresponding concentrations provides quantitative evidence of the reagent specificity differences.  相似文献

The growth of mass media has complicated the relatioship between the courts and the media. Free press and fair trial rights are kept in balance by the use of judicial restraints and remedies such asvoir dire, change of venue, and gag orders. This balance has shifted back and forth during the past two decades. Current case law and legal codes are inconsistent and provide insufficient guidance to judges in their use of restraints and remedies. Nor is there a body of empirical research on the impact of news coverage and juror behavior capable of informing the courts at this time. In this paper, we review and critically assess the empirical social science literature as it pertains to the legal issues involving free press and fair trial. We argue that carefully conducted empirical research could provide important information to the courts. We suggest research directions and methodological caveats to increase legal relevance and scientific validity.  相似文献

Despite the significant role that skin color plays in material well-being and social perceptions, scholars know little if anything about whether skin color and afrocentric features influence political cognition and behavior and specifically, if intraracial variation in addition to categorical difference affects the choices of voters. Do more phenotypically black minorities suffer an electoral penalty as they do in most aspects of life? This study investigates the impact of color and phenotypically black facial features on candidate evaluation, using a nationally representative survey experiment of over 2000 whites. Subjects were randomly assigned to campaign literature of two opposing candidates, in which the race, skin color and features, and issue stance of candidates was varied. I find that afrocentric phenotype is an important, albeit hidden, form of bias in racial attitudes and that the importance of race on candidate evaluation depends largely on skin color and afrocentric features. However, like other racial cues, color and black phenotype don’t influence voters’ evaluations uniformly but vary in magnitude and direction across the gender and partisan makeup of the electorate in theoretically explicable ways. Ultimately, I argue, scholars of race politics, implicit racial bias, and minority candidates are missing an important aspect of racial bias.  相似文献

This study examines factors that may influence an employee to exit an organization. Factors that are considered to influence exit are derived primarily from Hirschman’s model of exit, voice, loyalty, and neglect. Other variables considered are public service motivation, job satisfaction, pay satisfaction, gender, race, supervisory status, and agency. The study evaluates the relationships between these variables using data obtained from the United States’ 2010 Federal Employee Viewpoint Survey. Overall, the data suggest that there is a slight tendency of public employees to be intrinsically motivated.  相似文献

An increasing number of studies in political communication focus on the “sentiment” or “tone” of news content, political speeches, or advertisements. This growing interest in measuring sentiment coincides with a dramatic increase in the volume of digitized information. Computer automation has a great deal of potential in this new media environment. The objective here is to outline and validate a new automated measurement instrument for sentiment analysis in political texts. Our instrument uses a dictionary-based approach consisting of a simple word count of the frequency of keywords in a text from a predefined dictionary. The design of the freely available Lexicoder Sentiment Dictionary (LSD) is discussed in detail here. The dictionary is tested against a body of human-coded news content, and the resulting codes are also compared to results from nine existing content-analytic dictionaries. Analyses suggest that the LSD produces results that are more systematically related to human coding than are results based on the other available dictionaries. The LSD is thus a useful starting point for a revived discussion about dictionary construction and validation in sentiment analysis for political communication.  相似文献

The pursuit of intelligence on the German economy by the United States Army Air Corps prior to 1942 revealed great gaps in US knowledge of the German economy. This encouraged joint efforts with British Intelligence. The Air Corps exploited sources creatively to find German industrial targets. Its specialized needs persuaded it to try to establish an Air Corps intelligence gathering section. The Air Corps clashed with the Army over access to economic data. Its need for economic intelligence merged with its political goal of making strategic bombing its primary mission. Intelligence gathering efforts ultimately translated into the creation of air warfare strategy.  相似文献
