Nonprofit property tax exemption has become a major policy issue as the collapse of the housing market, the Great Recession, and property tax caps have threatened local tax collections. Consequently, many local governments have sought to obtain payments in lieu of taxes (PILOTs) from charities that are formally exempt from property taxes. Using a 2010 survey of local government officials in Indiana, this article examines whether support for PILOT policies is related to officials’ personal involvement with nonprofits, their views on government–nonprofit relationships, the type of position they hold, the level of economic distress in the county, local political conditions, and local nonprofit wealth. The findings support most of these hypotheses but also show that attitudes toward PILOTs appear to be shaped by somewhat different concerns than attitudes toward services in lieu of taxes (SILOTs).  相似文献

It is generally understood that households make tradeoffs between housing costs and other living expenses. In this article, we examine the relationship between health-related outcomes and housing-induced financial burdens for renters in one of the most expensive cities in the world, New York, New York. Drawing from the Housing Vacancy Survey for 2011, a representative survey conducted by the U.S. Census Bureau of more than 16,000 households in New York City, we estimate the effect of housing cost burden on the overall health of renters and the extent to which they have postponed various types of medical services for financial reasons. Results show that higher out-of-pocket rent burdens are associated with worse self-reported health conditions and a higher likelihood to postpone medical services for financial reasons. This relationship is particularly strong for those households with severe rent burdens. In addition, housing cost burden is equally or more important than other physical housing characteristics in explaining the variation in self-reported general health status and health care postponement. These findings are robust across specifications with different degrees of household, unit/building, and neighborhood controls, and among longstanding and newer renters. Our findings point to the importance of considering health-related outcomes when designing housing policies, and that housing subsidies should target both renters' out-of-pocket costs and place-based repair and maintenance.  相似文献

Local governments commonly pursue environmental objectives that exceed state and federal minimum requirements. Although research informs our understanding of factors that lead cities to adopt such policy goals, the underlying mechanisms employed to achieve them are not well understood. This article examines factors that drive the choice of policy instruments that cities use to pursue local environmental objectives. The literature links the structure of the local governing body, characteristics of the community and target populations, and the nature of the policy problem to instrument selection. Building on this, the authors model the dynamics shaping cities' use of regulations, financial incentives, or combination thereof, to pursue a variety of different environmental objectives. Results indicate that community racial composition and political leaning influence instrument choice when policy targets the public at large. Alternatively, when policy targets particular stakeholder groups, such as developers, the characteristics of the local governing body are of greater importance.  相似文献

Social media is becoming increasingly important for communication and community building, yet research on the use of social media by non‐profit organisations is limited and largely restricted to content analysis of social media comments. This article contributes to addressing this research gap, through a survey‐based study of the perspectives of key informants in U.K. Local Authority fostering teams on their use of social media. Specifically, it examines the extent to which the Facebook activity of local authority fostering teams is aligned with the principles of successful social media engagement, as represented by dialogic strategies and outcomes. A questionnaire on the use of Facebook was circulated to all local authority fostering teams in England. Findings suggest that although there is progress, many teams are at an early stage in their social media journey and that there is considerable variation between agencies. The limited evidence of engagement in relation to dialogic principles suggests that there is some adoption of a strategic approach. In particular, of the three dialogic principles associated with successful online engagement, two (updating and community building) were applied by about half of local authority fostering teams and the third (engagement) by just over a quarter.  相似文献

Although the relationship between decomposition and postmortem interval has been well studied, almost no studies examined the potential effects of physical disturbance occurring as a result of data collection procedures. This study compares physically disturbed rabbit carcasses with a series of undisturbed carcasses to assess the presence and magnitude of any effects resulting from repetitive disturbance. Decomposition was scored using visual assessment of soft tissue changes, and numerical data such as weight loss and carcass temperature were recorded. The effects of disturbance over time on weight loss, carcass temperature, soil pH and decomposition were studied. In addition, this study aimed to validate some of the anecdotal evidence regarding decomposition. Results indicate disturbance significantly inversely affects both weight loss and carcass temperature. No differences were apparent between groups for soil pH change or overall decomposition stage. An insect-mediated mechanism for the disturbance effect is suggested, along with indications as to why this effect may be cancelled when scoring overall decomposition.  相似文献

Limited research exists on the impact of prison mother and baby unit (MBU) residence. Research in the UK suggests women in MBUs have lower prevalence of mental disorder. Higher rates of mother-child attachment for women in prison nurseries in the US have been reported. Eighty-five pregnant women were interviewed at baseline and 62 followed up in nine different prisons. The Edinburgh Postnatal Depression Scale (EPDS) was used to measure perinatal depression; the World Health Organisation Quality of Life (WHOQOL – BREF), for quality of life; and the Mother-to-Infant Bonding Scale (MIBS) for mother-child bonding. EPDS scores were higher at baseline than follow-up. Women admitted to MBUs had lower EPDS scores at baseline and follow-up, and this reduction was greater than for women not admitted to MBUs. WHO-QOL scores were higher at follow-up than baseline on all domains, except the social domain for those not admitted to MBUs. Findings suggest women with perinatal depression are less likely to be admitted to MBUs, and MBU placement may contribute to a reduction in perinatal depression. Increased QOL-BREF scores at follow-up suggest improved quality of life for all participants. Reduced support post-separation may contribute to lower social domain scores for women not admitted to MBUs.  相似文献

Two hundred prosecuting attorneys completed a survey concerning priorities in taking on animal cruelty cases and the factors that help or hinder prosecuting such cases. Respondents commented on the priority given such cases. Questions also addressed specific kinds of evidence that had been used to decide whether to take on a cruelty case and were used in court. Results showed that prosecutors most frequently relied upon “traditional” sources of evidence, including detailed medical and crime scene reports and good quality photographic evidence. Other sources of forensic evidence such as DNA, computer forensics, forensic accounting, blood, and trace evidence were rarely employed. Veterinary forensic evidence, including forensic necropsies and detailed medical reports, was viewed as an important factor by a majority of prosecutors in deciding whether to accept a case for prosecution and in achieving a successful outcome, but a need for additional training for investigators was indicated.  相似文献

Community college (CC) students make up 45% of American undergraduates, but little is known about their experiences of intimate partner violence (IPV), or accompanying service use and needs. The current study used a sequential confirmatory mixed methods design among a simple random sample of female CC students (n?=?435), of whom 112 have experienced IPV in the past 12 months. Of these IPV survivors, 20 participated in qualitative follow-up interviews. The study assess use and perceived usefulness of college and community based resources, extent of social support, and perceived need for and barriers to service access. Campus based resources were rated as more useful than community based resources. Faculty were identified as important supports for survivors. Those experiencing IPV reported lower rates of social support compared to other students. A range of supports and services were endorsed as possibly useful by survivors. Survivors need services to address life generated risks that compound barriers to college completion created by abuse. CC survivors often balance work and parenting with education, and may benefit from different services than survivors in other educational settings.  相似文献

The legal landscape surrounding adoption by lesbian, gay, bisexual, transgender, or questioning/queer (LGBTQ) parents continues to be dynamic and variable across the United States, yet the topic is generally viewed favorably by Americans and increasing numbers of LGBTQ adults are becoming adoptive parents. In this essay, we explore intersections of sexual orientation, gender identity, and adoption law. We discuss connections between parenting (including adoption) and marriage rights, highlight the influence of varying legal contexts and discrimination for LGBTQ adults who pursue adoption (including case examples from Florida after the gay adoption ban was lifted), and incorporating the perspectives of adoption‐agency personnel working with LGBTQ clients.  相似文献
