Developing greater understandings of socio-ecological relationships across urbanizing areas is increasingly recognized as important for the conservation and management of natural resources in a variety of development contexts. Efforts to do so have been hindered by a lack of consistent measures of urbanization and the challenge of integrating socio-cultural characteristics into definitions of urban. We present a novel method for linking perceptual definitions of urban, suburban, and rural to geospatial characteristics and demonstrate how the method can be used to map urban, suburban, and rural areas at multiple scales in central and eastern Massachusetts. Our method can facilitate comparative approaches to urban ecology, be used to scale up socio-ecological studies, and inform conservation research and practice in urbanizing areas. 相似文献

Reciprocal peer dislike was examined as a predictor of school adjustment and social relationship quality. One hundred and fifty‐one [69 male and 74 female, mean (M)age = 9.53, standard deviation (SD)age = .63 years] children completed measures of school liking, loneliness, and friendship quality twice over three months. From ratings of the amount of time participants liked to spend with individual classmates, social network analyses were used to determine reciprocal peer dislike. Curvilinear regression analyses revealed that reciprocal peer dislike at Time 1 predicted changes in the children's loneliness and friendship quality assessed as help, security, and closeness over three months. The findings support the conclusion that reciprocal peer dislike predicts aspects of school adjustment and social relationship qualities. 相似文献

What has happened to Australia's public housing? Thirty years of policy and outcomes, 1981 to 2011 下载免费PDF全文
This paper uses the release of the 2011 Australian Bureau of Statistics (ABS) census results and other recent and historical data sets to explore how Australian public housing has changed over the period 1981–2011. It summarises the contextual factors that have influenced housing provision and consumption in Australia over the past thirty years. The overall supply trends by tenure for Australia and each capital city are set out, followed by analysis of the demographics of public housing tenants, including age, household type, income, mobility, and workforce participation. Issues identified in the paper include insufficient stock and increasingly targeted households, representing a social and financial problem for housing agencies. The current stock is ill‐adapted to tenants' needs; if housing agencies re‐profile the housing to meet such needs, then they risk creating inflexible stock. The paper concludes with reflection on the future of public housing in Australia. 相似文献

It is well established in the literature that fathers who use violence harm women and children. Statutory child protection workers and other human service professionals now face strong injunctions to work with these men. However, insufficient attention has been given to considering the processes for intervening with fathers who use violence and the organisational context to support workers in refocusing their practice. Workers lack clear guidance, and organisations lack specific understandings of how to support workers in this complex area of practice. Australian research used co‐design with professionals in Communities of Practice supported by the Safe & Together Institute to explore the organisational context required to work with fathers who use violence. This paper presents findings of qualitative data gathered from surveys, focus groups, and ethnographic notes of 30 Community of Practice sessions. Working together, practitioners and researchers identified four essential elements to support organisational development and improve practice: leadership by senior managers; recognition that domestic violence work needs to strengthen collaborative working; extensive training, supervising, and coaching; and enhanced worker safety. Worker perspectives are critical in developing practice principles and identifying organisational mechanisms that support practitioners to work safely and effectively with fathers who use violence. 相似文献

Although survey research is one of the most frequently used methods for studying charitable giving, the quality of the data
is seldom stated or known. In particular, social desirability bias (SDB) has been found to distort data validity where respondents
tend to over-report what is socially desirable and vice versa. We argue that this phenomenon has not been fully understood
in the nonprofit context as existing social desirability scales are not appropriate to be used in giving surveys. Thus, this
paper is the first to extend understanding of SDB to the nonprofit context and to explore its motivating factors. Based on
a multidisciplinary literature review and qualitative interviews with various senior practitioners from the fundraising and
marketing research sectors, it is suggested that SDB is a multidimensional construct yielding five dimensions, namely, impression
management, self-deception, level of involvement, perceived benefits and social norms. The paper then discusses the implications
for nonprofit researchers and concludes with directions for future research. 相似文献

This research explores the health insurance coverage of various Hispanic subgroups in comparison to non-Hispanic whites and blacks. The impact of immigration status is also considered as we hypothesize that nativity, duration, and naturalization tap a possible process of structural acculturation that increases access to insurance coverage for Hispanic groups. We find that the immigration variables impact the type of insurance reported. However, race/ethnic disparities continue to exist, with the various Hispanic subgroups more likely to report miscellaneous government health insurance or no health insurance coverage as compared to non-Hispanic whites. 相似文献

Abstract Objective: Given recent approval for administration of a human papillomavirus (HPV) vaccine to men, it is important to assess the HPV-related perspectives of men and women. The purpose of this study was to examine gender differences in HPV knowledge, beliefs, and vaccine acceptance among college students attending 3 historically black colleges/universities in the Southeast. Participants and Methods: A nonprobability sample of 575 students completed a self-report questionnaire. Results: Males were significantly less likely to have heard of HPV, scored lower in HPV knowledge, were less likely to perceive HPV health outcomes as severe and that there was a benefit to vaccinate, reported fewer cues for vaccine acceptance, and perceived more barriers to vaccination compared to females (all p < .05). Conclusions: The gender disparities demonstrated in this study highlight the need to increase HPV-related communication/education to include men and to extend HPV research to a broader segment of the college population. 相似文献

This study examined the psychological well‐being of fathers and father–child relationships in families with a 7‐year‐old child conceived by donor insemination. Twenty‐four donor insemination families and comparison groups of 25 egg donation and 32 unassisted‐conception families were assessed using a standardized interview and questionnaires administered to the father, and father–child dyads participated in an observational assessment of father–child interaction. On the basis of perspectives from Parental Investment Theory and stress‐related models, it was expected that donor insemination fathers would show raised levels of psychological problems and a poorer quality of parenting and have more conflictual relationships with their children than genetically related fathers in egg donation and unassisted‐conception families. These hypotheses were not supported by the findings. Instead, it seems that commitment to parenthood may be more important than genetic relatedness for positive father–child relationships. 相似文献

Social utility theory suggests that labeling video news release (VNR) source material is the ethical decision (Wulfemeyer & Frazier, 1992), yet the persuasion knowledge model predicts that the effectiveness of VNRs will decrease as people become aware of this PR tactic (Friestad & Wright, 1994). Our study found that positive and negative effects were heightened when subjects read about VNRs and viewed a labeled VNR in a newscast. These subjects were most likely to recognize the VNR story source and least likely to perceive the story as credible. Neither reading nor labeling affected evaluations of the VNR message or featured company. 相似文献

Understanding the impact of urbanization on terrestrial biogeochemistry is critical for addressing society’s grand challenge of global environmental change. We used field observations and remotely sensed data to quantify the effects of urbanization on vegetation and soils across a 100-km urbanization gradient extending from Boston to Harvard Forest and Worcester, MA. At the field-plot scale, the normalized difference vegetation index (NDVI) was positively correlated with aboveground biomass (AGB) and foliar nitrogen (N) content and negatively correlated with impervious surface fraction. Unlike previous studies, we found no significant relationship between NDVI or impervious surface area (ISA) fraction and foliar N concentration. Patterns in foliar N appeared to be driven more strongly by changes in species composition rather than phenotypic plasticity across the urbanization gradient. For forest and non-residential development, soil nitrogen content increased with urban intensity. In contrast, residential land had consistently high soil N content across the gradient of urbanization. When field observations were scaled-up to the Boston Metropolitan Statistical Area (MSA), we found that soil and vegetation N content were negatively correlated with ISA fraction, an indicator of urban intensity. Our results demonstrated the importance of accounting for the influence of impervious surfaces when scaling field data across urban ecosystems. The combination of field data with remote sensing holds promise for disentangling the complex interactions that drive biogeochemical cycling in urbanizing landscapes. Empirical data that accurately characterize variations in urban biogeochemistry are critical to gain a mechanistic understanding of urban ecosystem function and to guide policy makers and planners in developing ecologically sensitive development strategies. 相似文献
