This study examined racial disparity in impacts that welfare use, substance abuse, depression, and intimate partner violence (IPV) make on substantiation of reported child maltreatment. A sample of 1493 African Americans, 848 Hispanics, and 2144 Whites was employed, extracted from the National Survey of Child and Adolescent Well-Being. Logistic regression results indicated that each ethnic subsample had a distinct set of significant risk factors for substantiation. For the African American subsample, relatively long periods spent receiving Temporary Assistance for Needy Families (TANF) reduced likelihood of substantiation, as did caregivers' alcohol dependence. For the Hispanic subsample, TANF receipt lowered substantiation's likelihood, while caregivers' drug use raised its likelihood. For the White subsample, caregivers' TANF receipt and substance abuse showed no significant impact. No subsample's substantiation likelihood appeared significantly affected by depression or IPV. Implications for services are suggested. 相似文献

This article examines whether altruistic behavior is habit forming. The basic premise is that if engaging in altruistic behavior when young is a good predictor of such behavior in adulthood, then this is consistent with the notion that altruistic behavior is habit forming. Using U.S. data, we examine donations of both money and time and find that engaging in charitable behavior when young is a strong predictor of adult altruistic behavior, with all other things equal. A major issue in the interpretation of this result is that the correlation between youthful and adult altruistic behavior may be due to some third variable that affects both. Although it is impossible to rule out such a possibility, we are able to control for family influences that likely could affect lifetime attitudes toward altruism. 相似文献

β-Chloroprene is used in the production of polychloroprene, a synthetic rubber. In 2010, Environmental Protection Agency (EPA) published the Integrated Risk Information System “Toxicological Review of Chloroprene,” concluding that chloroprene was “likely to be carcinogenic to humans.” This was based on findings from a 1998 National Toxicology Program (NTP) study showing multiple tumors within and across animal species; results from occupational epidemiological studies; a proposed mutagenic mode of action; and structural similarities with 1,3-butadiene and vinyl chloride. Using mouse data from the NTP study and assuming a mutagenic mode of action, EPA calculated an inhalation unit risk (IUR) for chloroprene of 5 × 10−4 per µg/m3. This is among the highest IURs for chemicals classified by IARC or EPA as known or probable human carcinogens and orders of magnitude higher than the IURs for carcinogens such as vinyl chloride, benzene, and 1,3-butadiene. Due to differences in pharmacokinetics, mice appear to be uniquely responsive to chloroprene exposure compared to other animals, including humans, which is consistent with the lack of evidence of carcinogenicity in robust occupational epidemiological studies. We evaluated and integrated all lines of evidence for chloroprene carcinogenicity to assess whether the 2010 EPA IUR could be scientifically substantiated. Due to clear interspecies differences in carcinogenic response to chloroprene, we applied a physiologically based pharmacokinetic model for chloroprene to calculate a species-specific internal dose (amount metabolized/gram of lung tissue) and derived an IUR that is over 100-fold lower than the 2010 EPA IUR. Therefore, we recommend that EPA's IUR be updated. 相似文献

The paper illustrates the desirability and feasibility of the computer simulation technique in socio-psychological research. A computer simulation model of a five-man industrial work group is constructed. After the model has successfully passed a two stage validation procedure, an experimentation phase is conducted. In a 2 times 3 replicated factorial experiment, five years of simulated weekly data is used to test several hypotheses which relate the independent variables–supervisory style and worker interpersonal orientation–to productivity, worker job satisfaction and group cohesiveness. The hypotheses were derived from the findings of prior short-lived laboratory and field research. The study indicates that the computer simulation approach is a valuable adjunct to the classical organizational research techniques. 相似文献

The paper reports on a large scale evaluation of two alternative models of undergraduate statistics courses. The traditional course orientation was compared with a problem-solving orientation in which the emphasis was on real world problem-solving, during the winter and spring quarters of 1973–74. The evaluation battery included behavioral and problem-solving skill measures. The findings indicate that improvements in statistics programs can be made. 相似文献

Identifying factors linked to the development of group consciousness is important toward bettering our understanding of group formation processes among marginalized ethnoracial groups. This study examines predictors of group consciousness among Asians and Asian Americans in the United States, focusing on numerous dimensions of this concept, including linked fate, panethnic group identification, and four specific sources of perceived group commonality and interests: (1) cultural, (2) economic, (3) political, and (4) racial. We use data from a national survey to examine socio-structural, political, discrimination, and immigration correlates associated with separate dimensions of Asian group consciousness. We found that perceiving interpersonal discrimination increased the importance of being Asian; heightened the odds of feeling linked fate with other Asian people; and enhanced the odds of identification as “Asian American.” Republicans and Independents were less likely to perceive different elements of Asian group consciousness compared to Democrats. Educational attainment, income, gender, employment status, ethnicity, and English-speaking comfortability had varying effects across certain measures of Asian group consciousness. For Asians and Asian Americans, interpersonal discrimination and certain socio-structural, political, and immigration factors may be especially meaningful toward the development of linked fate, shared group interests and commonalities, and panethnic identification, all of which are key toward activating group consciousness. 相似文献

This article explores the relationship between gender balance in the workforce and attitudes towards abortion worldwide. Studies on macro-level conditions related to abortion attitudes overlook the role of gender balance in the workforce—specifically the degree of female representation in a country's workforce. There are strong reasons why this factor could shape abortion attitudes. We argue that such a gender balance creates necessary conditions to break with traditional, anti-abortion ideology and facilitates dissemination and public acceptance of pro-choice views. We test this argument with two different datasets - the Integrated Values Survey and three waves of the International Social Survey Programme—along with two outcomes: general tolerance towards abortion and tolerance towards abortion for pregnant women of low income. Using three-level random intercept models and multiple controls for individual and country-level conditions, the results support our hypothesis: In countries with higher gender balance in the workforce, individuals display higher tolerance towards abortion. 相似文献

Using data from a unique series of surveys collected between 1963 and 2013, this study examines racial attitudes among young white adults in the Deep South over a 50-year period. Repeated surveys of University of Alabama students in 1963, 1966, 1969, 1972, 1983, 1988, and 2013 measured racial stereotypes, support for racial segregation, and in the 2013 study, racial resentment and support for ameliorative racial policies. Analyses show that in the 1960s endorsement of racial stereotypes was a powerful predictor of support for racial segregation. By the early 1970s, racial integration became a reality in the Deep South and, paralleling broad trends in U.S. society, endorsement of racial stereotypes and support for racial segregation declined. Simultaneously, threats to whites' position in the form of ameliorative racial policies (including affirmative action) emerged along with racial resentment. By 2013, racial resentment, rather than racial stereotyping, was the primary determinant of white students' opposition to racial change. Our findings support Herbert Blumer's (1958) argument that racial prejudice exists in a sense of group position, and that it functions to preserve the advantaged position of the dominant group regardless of changes in the form that prejudice takes. 相似文献

Effective student evaluation of instructor instruments must provide norm, or comparative, data to aid interpretation. This note highlights an innovative factor score comparative report. Rather than merely reporting comparative data on individual questions items, the innovative report provides comparative percentile data on the six factors underlying our thirty-three item questionnaire. The faculty indicated overwhelming support for the new report. The note also briefly mentions three other activities that are essential for student evaluation of instructor data to improve teacher effectiveness. Our goal is to stimulate other colleges to adopt the innovative norming practice once they have validated their local evaluation instruments. College-wide improvement of teaching will occur through such do-it-yourself efforts and only decision science faculty are technically qualified to lead such efforts. 相似文献
