A retrospective qualitative constant comparative analysis of the stories of English speaking women (N==22) who mothered children age 6 or under, while experiencing abuse at the hands of a male partner, was conducted. The emergent theory of Attentive Surveillance (AS), a vital, proactive, complex process of monitoring and prioritizing, was identified. Two non-linear and interrelated stages emerged. One, Understanding Circumstances (UC) is a gradual increase of awareness that the family environment and a woman’s ability to achieve her mothering standards are affected by her partner’s behavior. The second stage, Prioritizing Standards (PS), is a deliberate or a subconscious balancing act of assessing needs, adapting, and ranking mothering standards while still mothering as close to the original standards as possible. Recommendations for professionals, based on AS, in supporting mothers existing capacities to foster mother-child relationships and healthy child outcomes in the context of intimate partner violence are provided.  相似文献

The Texas death penalty statute originally approved by the United States Supreme Court in Jurek v. Texas (1976) was legislatively amended as a result of the Court’s decision in Penry v. Lynaugh (1989). The changes were intended to focus on increasing jurors’ ability to give mitigating effect to evidence in sentencing. Using data from the Capital Jury Project, we compared juror comprehension of sentencing guidelines, punishment responsibility, and deliberations in sentencing among a sample of 123 Texas jurors who deliberated under the Jurek and Penry statutes. In each area, we found that the amended statute failed to guide capital juror decision-making as intended.  相似文献

Elevators are mechanical transportation devices used to move vertically between different levels of a building. When first developed, elevators lacked the safety features. When safety mechanisms were developed, elevators became a common feature of multistory buildings. Despite their well-regarded safety record, elevators are not without the potential for danger of injury or death. Persons at-risk for elevator-related death include maintenance and construction workers, other employees, and those who are prone to risky behavior. Deaths may be related to asphyxia, blunt force, avulsion injuries, and various forms of environmental trauma. In this review, we report on 48 elevator-related deaths that occurred in nine different medicolegal death investigation jurisdictions within the United States over an approximately 30-year period. The data represents a cross-section of the different types of elevator-related deaths that may be encountered. The review also presents an overview of preventive strategies for the purpose of avoiding future elevator-related fatalities.  相似文献

We use 10 years of California administrative data with a regression kink design to estimate the causal impacts of benefits in the first state-level paid family leave program for women with earnings near the maximum benefit threshold. We find no evidence that a higher weekly benefit amount (WBA) increases leave duration or leads to adverse future labor market outcomes for this group. In contrast, we document that a rise in the WBA leads to an increased likelihood of returning to the pre-leave firm (conditional on any employment) and of making a subsequent paid family leave claim.  相似文献

Facing fragmented institutions and partisan polarization, officials in the United States often attempt to engineer policy change without assembling new legislative majorities. To this end, they have increasingly employed demonstration projects, policy innovations undertaken by administrative agencies designed to test alternative approaches to implementation or service delivery on a limited segment of the target population and for a limited period of time. Despite the increasing importance of demonstration projects, they are an undertheorized source of policy change. In this article, we conceptualize demonstration projects as part of a class of experimental institutions that, while incremental in scope, have the potential to ‘scale up’ into more substantial reforms. Data from three Medicare demonstrations suggest that policy change is more likely when programmes generate strong support constituencies; minimize administrative and infrastructural costs; are undertaken in contexts with few veto points; and align with the time horizons of elected officials.  相似文献

Planning and preparing for life after high school is a central developmental task of American adolescents, and may be even more critical for low-income youth who are less likely to attend a four year college. This study investigates factors that led to the effects of the New Hope Project, a work-based, anti-poverty program directed at parents on youths’ career-related thoughts and planning. The New Hope project was implemented in Milwaukee, WI, during the mid-1990s. 745 families participated (52 % male children; 56 % African American; 30 % Latino, and 15 % White non-Hispanic) and half were randomly selected to receive New Hope benefits, which included earnings supplements, job search assistance, and child and health care subsidies for 3 years. Importantly, effects on youths’ future orientation were found 8 years after the program began (5 years after benefits ended). The present study investigates what factors sustained these positive impacts over time. Results indicate that parental perceptions of reading performance mediate the effects of New Hope on youths’ cynicism about work. Additionally, parental perceptions of reading performance and youths’ educational expectations mediate the effects of New Hope on boys’ pessimism about future employment. These findings highlight the importance of youths’ educational development to their career-related thoughts and planning.  相似文献

The Abbott Government announced its White Paper review of the Australian Federation on June 28, 2014. Set against this backdrop, discussions of the future of Australian local government may provoke an assumption that its role will be cruelled. However, reflection suggests that such an assumption is misplaced. In particular, when the complexities of regionalism in Australia are considered, the potential role of local government begs revisiting. We argue that local government ought to adopt a forthright position in the current debate, particularly with respect to financial reform.  相似文献

Past research has shown that adolescents justify social exclusion based on concerns for group functioning, and yet, to date, no study has evaluated whether group functioning justifications shift or remain stable across different exclusion contexts. In this study, we systematically manipulated exclusion context (i.e., competitive or noncompetitive soccer groups) and individual characteristics of the target of exclusion to test the nature of the interaction between these factors during exclusion judgments. Adolescents’ (N = 201; 61 % Female) exclusion judgments differed across contexts only when an individual’s ability was under consideration. Intergroup (i.e., gender, nationality) and interpersonal (i.e., aggression, shyness) characteristics overwhelmed contextual considerations. Results indicate the complexity of factors weighed by adolescents when making exclusion judgments, and suggest the need for extension of the present findings to understand more fully the interaction between the context of exclusion and individual characteristics in exclusion judgments.  相似文献
