Local government policymakers across the developed world have frequently employed municipal amalgamation to improve the operation of local councils, and New Zealand is no exception. This paper empirically examines claims made in Potential Costs and Savings of Local Government Reform in Hawke’s Bay that the merger of the five local authorities in the Hawke’s Bay Region of New Zealand would generate significant cost-savings. We empirically test for the existence of scale economies in a single merged Hawke’s Bay council and find that no cost-savings can be expected. This removes a key argument for a forced Hawke’s Bay amalgamation. 相似文献

Efficiency approaches to the question of whether population size matters to optimal local government have proved largely inconclusive. However, recent exploratory empirical work employing an effectiveness approach – as proxied by citizen satisfaction survey data – offers a promising way forward. The present paper seeks to build upon an earlier cross-sectional analysis of Victorian local government by employing longitudinal data over a three-year period – 2008 to 2010 – for Victorian local authorities. The greater depth of data confirmed the positive associations with population density but suggests that negative linear relationships dominate over parabolic associations for population size. This result underlines the need for the collection of more local government citizen satisfaction data by Australian local government systems, given its potentially fruitful application in tackling contentious questions in contemporary local government policy debates. 相似文献

Adolescent romantic relationships have the potential to affect psychological functioning well into adulthood. This study assessed adolescent romantic relationship qualities as long-term predictors of psychological functioning utilizing a longitudinal multi-method, multi-informant study of 80 participants (59% female; 54% Caucasian, 35% African American, 11% mixed or other race) assessed at age 17 along with their romantic partners and at ages 25–27. Controlling for gender, family income, and baseline mental health, partner-reported hostile conflict at age 17 predicted relative increases in internalizing behaviors from age 17 to 27. In contrast, observed teen support with their partner during a help-seeking task at age 17 predicted relative decreases in externalizing behaviors over time. The results are interpreted as suggesting qualities that may help determine whether adolescent romances have positive vs. negative long-term psychological health implications. 相似文献

This paper examines the long‐term effect of project‐based housing assistance—public housing and private assisted housing—on work, earnings, and welfare receipt. We use the Panel Study of Income Dynamics–Assisted Housing Database to identify women ever living in project‐based assisted housing and to create comparison groups using propensity scores. Analyses show no evidence that moving into this type of assisted housing is associated with sustained reductions in employment rates, work hours, or earnings. Although welfare rates decline, they remain higher for assisted housing recipients compared with nonrecipients. Overall, these findings align with those of recent experimental and nonexperimental studies that include other forms of housing assistance and cover different time periods. © 2009 by the Association for Public Policy Analysis and Management. 相似文献

The present study provides a comparative analysis of sexual-minority and heterosexual emerging adult women’s experiences seeking support for sexual issues from parents and friends. Participants included 229 college women (88 sexual-minority women; 141 heterosexual women), ranging from 18 to 25 years of age, who provided written responses to an inquiry about a time they went to friends and parents for support for a issue related to their sexuality. Responses indicated that the majority of participants had sought support from either a parent or a friend and that mothers and female friends were more likely involved than fathers or male friends, respectively. Sexual issues that participants reported discussing with parents and friends were inductively grouped into five categories: dating and romantic relationships, sexual behavior, sexual health, identity negotiation, and discrimination and violence. Issues that were discussed differed based on sexual orientation identity and the source of support (parent or friend); they did not differ by age. Participants generally perceived parents and friends’ responses as helpful, though sexual-minority participants perceived both parents and friends’ responses as less helpful than did heterosexual participants. Overall, results suggest both similarities and differences between sexual-minority and heterosexual young women’s experiences seeking support for sexual issues from parents and friends. 相似文献

Student engagement is an important contributor to school success, yet high school students routinely describe themselves as
disengaged. Identifying factors that alter (increase) engagement is a key aspect of improving support for student achievement.
This study investigated students’ perceptions of autonomy, teacher connection, and academic competence as predictors of changes
in student engagement within the classroom from the start to the end of a course. Participants were 578 (58% female) diverse
(67.8% White, 25.2% African American, 5.1% Hispanic, 1.2% Asian American) high school students from 34 classrooms who provided
questionnaire data both at the start and the end of a single course. Novel results from a cross-lagged model demonstrated
that students who perceived their classrooms as allowing and encouraging their own autonomy in the first few weeks increased
their engagement throughout the course, rather than the typical decline in engagement that was demonstrated by students in
other classrooms. This finding is unique in that it extended to both students’ perceptions of engagement and observations
of student engagement, suggesting a fairly robust pattern. The pertinence of this finding to adolescent developmental needs
and its relationship to educational practice is discussed. 相似文献
