We examined the Big Five personality traits of Agreeableness, Conscientiousness, Emotional Stability, Extraversion, and Openness, as well as four narrower traits of Aggression, Optimism, Tough-Mindedness, and Work Drive in relation to absences from school for middle- and high-school students. Participants were 248 seventh grade students, 321 tenth grade students, and 282 twelfth grade students. Most of the Big Five absence correlations were significant in the expected direction at all 3 grade levels. While Aggression, Optimism, Work Drive were significantly related to absences, only Work Drive added incremental variance to the prediction of absences beyond the Big Five traits. Study results were generally similar across grade levels. Findings were discussed in terms of dispositional absenteeism, the generalizability of the Big Five trait model, and the utility of more narrowband traits. Implications were drawn for early identification of absence-prone students and the precedent role of personality variables in school absence research on the effects of other variables, programs, and interventions.  相似文献

We analyze the relationship between prenatal WIC participation and birth outcomes in New York City from 1988-2001. The analysis is unique for several reasons. First, we have over 800,000 births to women on Medicaid, the largest sample ever used to analyze prenatal participation in WIC. Second, we focus on measures of fetal growth distinct from preterm birth, since there is little clinical support for a link between nutritional supplementation and premature delivery. Third, we restrict the primary analysis to women on Medicaid who have no previous live births and who initiate prenatal care within the first four months of pregnancy. Our goal is to lessen heterogeneity between WIC and non-WIC participants by limiting the sample to highly motivated women who have no experience with WIC from a previous pregnancy. Fourth, we analyze a large sub-sample of twin deliveries. Multifetal pregnancies increase the risk of anemia and fetal growth retardation and thus may benefit more than singletons from nutritional supplementation. We find no relationship between prenatal WIC participation and measures of fetal growth among singletons. We find a modest pattern of association between WIC and fetal growth among U.S.-born Black twins. Our findings suggest that prenatal participation in WIC has had a minimal effect on adverse birth outcomes in New York City.  相似文献

Abstract: This is a case study of some aspects of teacher education policy formation in Australia. Between 1960 and 1972 the States sought to obtain from the national government specific purpose grant-aid for the training of their teachers, in addition to that already provided indirectly by grants to the States for their universities. The national government gave way, step-by-step, to this pressure, but “imposed” the broad condition of corporate “autonomy” for grant-aided tertiary educational institutions, instead of State departmental “control” of teacher training. The paper also considers what perspectives are suggested by this case study for the development of theories of public policy in the Australian federal system of government.  相似文献

Seeking or receiving compensation after injury is frequently associated with poor recovery. Previous research has shown that the stressful nature of compensation procedures and perceived injustice may cause secondary harm. This study examined compensation system experiences in compensation claimants in Victoria, Australia, and explored the relationship between these experiences and injury outcomes. One hundred and sixty compensable patients (120 male, 75.0 %) aged 18–67 years (M?=?43.01, SD?=?14.31), hospitalized for an injury in a motor vehicle crash (n?=?137) or at work (n?=?23), participated. Participants completed questionnaires about compensation system experience, pain, and psychological symptoms 12 months after injury. Principal component analysis (PCA) of the compensation system experience items revealed three components explaining 66.64 % of the variance in compensation experience: (1) “negative procedural experience” (47.29 %), (2) “compensation supported recovery” (10.43 %), and (3) “positive procedural experience” (8.92 %). Worse experience on all components was associated with worse pain (severity, interference, catastrophizing, disability) and psychological symptoms (anxiety, depression, PTSD, perceived injustice). Compensation system experience reflected both negative and positive procedural factors, and feeling supported through recovery. Most participants reported having positive experiences; however, those who were frustrated or stressed from compensation procedures had worse pain and psychological health outcomes. While this association is likely to be bidirectional with “non-recovery” also impacting on compensation experience appraisals, compensation schemes should nonetheless address modifiable sources of procedural injustice (e.g., arduous paperwork and approvals processes) and reinforce procedures that generate perceptions of support (e.g., timely and appropriate access to health services).  相似文献

The demographic evidence of gender bias in many countries has provided an impetus for finding ways to study the status of women in developing countries. Because of the lack of accurate intra-household data, Deaton [1989 Deaton, A. 1989. Looking for Boy–Girl Discrimination in Household Expenditure Data. World Bank Economic Review, Vol.3, No.1: pp.1–15 [Google Scholar]] introduced a method for using household expenditure data to infer discrimination in the allocation of goods between boys and girls. Few studies of discrimination using the method, however, have detected bias even though alternative indicators suggest it is a serious problem. In this paper, we study the case of Papua New Guinea, a country in which there are many indicators of severe gender bias. Discrimination in the allocation of goods between boys and girls within households in Papua New Guinea is examined using Deaton's outlay-equivalent ratio method. Adding a boy to the household reduces expenditure on adult goods by as much as would a nine-tenths reduction in total outlay per member, but girls have no effect on adult goods expenditure. The hypothesis of Haddad and Reardon [1993 Haddad, L and Reardon, T. 1993. Gender Bias in the Allocation of Resource within Households in Burkina Faso: a Disaggregated Outlay Equivalent Analysis. Journal of Development Studies, Vol.29, No.2: pp.260–76 [Google Scholar]] that gender bias is inversely related to the importance of female labour in agricultural production is not supported. Sensitivity analysis shows that bias in rural areas occurs equally regardless of the age of the household head, while bias against girls may be less in regions of the country that have ethnic groups which practice matrilineal descent.  相似文献

Studies of Web use during elections have focused mainly on the content of Web sites and on the major factors driving parties' and candidates' adoption of the technology. Evaluations of the electoral impact of Web campaigns have been more limited. This article examines the nature and extent of Web use by voters and parties in the 2007 Australian federal election, focusing particularly on the consequences of Web 2.0 campaigning for candidate vote share. The findings show differing levels of commitment to older and newer e-campaigning technology across parties and their supporters and significant electoral advantages are associated with minor parties candidates using Web 2.0 campaign tools. The results confirm existing studies' findings about the impact of Web campaigns on contemporary elections, but that these effects are moderated by the type of Web tools used and party using them.  相似文献

Purpose

Many criminological scholars explore the social causes of crime while giving little consideration to the possibility that genetic factors underlie the observed associations. Indeed, the standard social science method (SSSM) assumes genetic influences do not confound the association between X and Y. Yet, a nascent stream of evidence has questioned the validity of this approach by revealing many criminological variables are at least partially affected by genetic influences. As a result, a substantial proportion of the literature may be misspecified due to uncontrolled genetic factors. No effort has been made to directly estimate the extent to which genetic confounding has biased the associations presented in criminological studies.

Methods

The present study seeks to address this issue by drawing on simulated datasets.

Results/Conclusions

Results suggest genetic confounding may account for a negligible portion of the relationship between X and Y when their correlation (ryx) is larger than the correlation between genetic factors and Y (i.e., ryx > ryg). Genetic confounding appears to be much more problematic when the correlation between X and Y is in the moderate-to-small range (e.g., ryx = .20) and the genetic effect is in the moderate-to-large range (e.g., ryg ≥ .30).  相似文献
