Using data from 8 random assignment studies and employing meta‐analytic techniques, this article provides systematic evidence that welfare and work policies targeted at low‐income parents have small adverse effects on some school outcomes among adolescents ages 12 to 18 years at follow‐up. These adverse effects were observed mostly for school performance outcomes and occurred in programs that required mothers to work or participate in employment‐related activities and those that encouraged mothers to work voluntarily. The most pronounced negative effects on school outcomes occurred for the group of adolescents who had a younger sibling, possibly because of the increased home and sibling care responsibilities they assumed as their mothers increased their employment.  相似文献

This study examines how two aspects of formalization of grievance procedures affect grievance procedure effectiveness: written versus oral presentation of grievance and the level of union and management authorized to resolve grievances at the first step. Several demographic variables were controlled for: size of bargaining unit, percentage of organization represented, number of grievances filed, and industry. A sample of 46 firms, representing a broad cross-section of unionized companies in the private sector, was obtained with the help of the American Arbitration Association. Results indicate that more formal grievance procedures (e.g., written presentation) are positively related to resolution rates at the first step. The number of grievances field and the size of the bargaining unit were positively related to total resolution rates prior to arbitration. We thank the American Arbitration Association for making this study possible.  相似文献

Codes of Ethics: What Are They Really and What Should They Be?   总被引:4,自引:0,他引:4  
Codes of ethics are prevalent in major corporations around the world. They are seen as the first tangible commitment to being ethical. This paper examines codes of ethics and tries to establish what they are, how they are developed and their net utility. We then proffer the idea of codes as the first part of a five-stage process that leads to an overall corporate commitment to being ethical in one's business dealings.  相似文献

Rural and small town places in developed economies are aging. While attention has been paid to the local transportation needs of rural seniors, fewer researchers have explored their regional transportation needs. This is important given policies that have reduced and regionalized many services and supports. This article explores mobility constraints impeding rural seniors' access to regionalized services using the example of northern British Columbia. Drawing upon several qualitative studies, we explore geographical, maintenance, organizational, communication, human resources, infrastructure, and financial constraints that affect seniors' regional mobility. Our findings indicate that greater coordination across multiple government agencies and jurisdictions is needed and more supportive policies and resources must be in place to facilitate a comprehensive regional transportation strategy. In addition to discussing the complexities of these geographies, the article identifies innovative solutions that have been deployed in northern British Columbia to support an aging population. This research provides a foundation for developing a comprehensive understanding of the key issues that need to be addressed to inform strategic investments in infrastructure and programs that support the regional mobility and, hence, healthy aging of rural seniors.  相似文献

OBJECTIVE: Maryland became the first state to pass a vaccination law requiring college and university students living on campus to obtain a meningococcal vaccination or to sign a waiver refusing vaccination because college students are at increased risk for disease. The authors sought to identify how Maryland colleges addressed the law and determine whether schools were in full compliance. PARTICIPANTS: The authors surveyed 32 college/university administrators via a self-administered questionnaire. METHODS: The authors calculated vaccination and waiver rates and assessed compliance with the law overall and with specific law components. RESULTS: Among 28 participating schools, annual vaccination rates and waiver rates among students during 2000-2004 ranged from 66%-76% and 12%-17%, respectively. Two (7%) schools were compliant with all components of the law. CONCLUSIONS: Mandatory vaccination laws do not ensure compliance at the college and university level. Mandatory reporting, increased education, and collaboration between colleges and universities and public health agencies are needed.  相似文献

The survey reported here found disparities in the impact of the introduction of the National Minimum Wage on disabled people. These were associated with age, gender, impairment and type of employment setting. The main determinant of whether individuals gained from the NMW was their status as claimants of welfare benefits. We also found evidence that paid hours had been reduced to implement the NMW with no net increase in earnings, possibly to enable people to retain benefits entitlements. We make recommendations about how the anomalies can be tackled. It may be unrealistic to expect the Act to have been implemented fully so soon after it became law and some of the anomalies found may eventually disappear. However, many of the inequalities uncovered by this survey are not addressed by the NMW, specifically those inequalities associated with impairment and gender.  相似文献

The community economic development (CED) framework has its rootsat the margins of society but has gained a broader interest.This paper examines some key principles associated with theCED framework. Interviews with practitioners within three CEDorganizations in Vancouver resulted in themes that link CEDas a strategy for sustaining a broader vision of the organizations.CED ventures provide opportunities that enhance the connectionfor marginalized peoples to participate in local community organizations.Yet, there are challenges around delivering services withinan alternative framework operationalized within a market-basedparadigm. Nevertheless, CED initiatives can have far reachingimpacts beyond the individual and the organization. Indeed,CED is about networks of communities within communities.  相似文献

Consider comparing between two treatments a response variable, whose expectation depends on the value of a continuous covariate in some nonlinear fashion. We fit separate segmented linear models to each treatment to approximate the nonlinear relationship. For this setting, we provide a simultaneous confidence band for the difference between treatments of the expected value functions. The treatments are said to differ significantly on intervals of the covariate where the simultaneous confidence band does not contain zero. We consider segmented linear models where the locations of the changepoints are both known and unknown. The band is obtained from asymptotic results.  相似文献

This paper investigates whether children later reported as having been unwanted or mistimed at conception will, when compared with children reported as wanted, show adverse effects when the following criteria are applied: receipt of antenatal care before the sixth month of gestation, supervised delivery, full vaccination of the child, and child growth (stunting). The study uses data from five recent Demographic and Health Survey enquiries in Bolivia, Egypt, Kenya, Peru, and the Philippines. In Peru, children unwanted at conception were found to have significantly worse outcomes than other children, but in the other countries, a systematic effect was found only for receipt of antenatal care. Weak measurement of the complex concept of wantedness may have contributed to these results. Birth order of the child, with which wantedness is inextricably linked, has more powerful and pervasive effects, with first-born and second-born children being much less likely to show adverse effects.  相似文献
