The aim of this study is to propose the application of landscape ecology in planning urban ecological networks to conserve nature in urban landscapes and to develop a sustainable use of urban lands. Compared to the classical planning approach based on socio-economic land suitability, the principles of landscape ecology are helpful simultaneously conserving the ecological processes of landscapes and their steady changes. This approach could help in defining sustainable landscape development, aiming for a balance between both physical and natural systems in urban areas. This research is focused on the ecological networks in Tehran’s metropolitan area as a case study to provide a model for network planning in other urban areas, where urbanization seriously threats the natural environment. In concluding this research, the spatial structure and function of the area are studied and categorized based on the patch-corridor-matrix model. The paper concludes with methods of intervention and suggestions for the structural and functional improvement of urban landscapes towards achieving a more sustainable form of land use planning.  相似文献

Large parts of urban space around the world exist of small-scale plots such as domestic gardens. These small-scale urban spaces carry potential for enhancing biodiversity, sustainability and ecosystem services in and beyond cities. However, domestic gardening and residential garden designs are often guided by aesthetics and ease more than by the aim to create habitat and biological diversity. Yard-management decisions impact socio-ecological systems in various ways, for example through irrigation patterns, fertilization or the use of pesticides or through the choice for exotic species that may become invasive over time. Yard-management decisions can also positively influence the presence of pollinators, improve soil quality or even foster small scale ‘Wildlife Habitats’ that can function as ecological stepping stones to the wider environment. In this paper a pilot assessment is presented of the contribution of residential front-yards in Phoenix (Arizona) and Maastricht (The Netherlands) to biodiversity, ecosystem services and sustainability by applying the BIMBY (Biodiversity in My (Back) Yard) framework.  相似文献

ABSTRACT

This study presents findings from a longitudinal study of the Mulberry Bush School (MBS), a therapeutic residential special school in England which provides an integrated approach to education and care for children aged between 5 and 13 years. Four cohorts were followed (23 = boys; 13 = girls), each for a consecutive 3-year period, approximating children’s time at the MBS. Children showed significant improvements in their socio-emotional, behavioural and academic development. The picture is more mixed for children’s attachment representations, which might be expected of the vulnerable and severely traumatised children who make up the MBS population. The importance of these improvements stem from the fact that they were achieved in the face of the exceptional disadvantages and challenges that characterise the lives of all children who attend the MBS. This is testimony to their achievement, and to the potential of the residential special school as a therapeutic learning environment.  相似文献

This study examined the role of public relations in Antonio Gramsci’s concept of cultural hegemony, specifically in a counterhegemony. Dr. Martin Luther King, Jr.’s preparation for the 1968 Poor People’s Campaign serves as a test case on how public relations can help subordinate groups confront a hegemony. This paper suggests that Gramsci’s philosophy provides an analytical heuristic for researching instances of contestation. Examining counterhegemonic campaigns offer public relations practitioners a means both to think about and to intervene in the world more effectively.  相似文献

Economists often rely on the Berg et al. (1995) trust game, or variants thereof, to identify levels of trust and reciprocity, which are fundamental to discussions of social capital. But to what extent is behavior in this game sensitive to the way the instructions are framed? We use the Berg et al. trust game played for ten rounds with random re-matching to study this. We implement a number of variations in the way the game is presented to subjects. We show that levels of trust, reciprocity and returns to trust are significantly higher under “goal framing”, which highlights the conflict inherent in the game, between self-interest and maximizing social surplus. Furthermore, with such framing, trust measured via the experimental game exhibits significant positive correlation with trust measured via the Social Values Orientation questionnaire.  相似文献

ABSTRACT

The language one uses for self-identification can be instrumental in the development and integration of one’s sense of self. This is particularly true regarding gender, gender identity, and sexual orientation. This seems to be particularly marked with use of the term “queer.” This research project explored terms that college-aged people use for self and other reference, especially use of the word queer. The results from this study provide empirical evidence that college-aged people have reclaimed the word queer as acceptable for gender or sexual orientation identification, although it is not the most frequent term used for their own self-identification.  相似文献

We studied a population of Cooper’s hawks (Accipiter cooperii) in Tucson, Arizona from 1994 to 2005. High rates of mortality of nestlings from an urban-related disease prompted speculation that the area represented an ecological trap and habitat sink for Cooper’s hawks. In this paper, we used estimates of survival and productivity from 11years of monitoring to develop an estimate of the rate of population change, λ, for Cooper’s hawks in the area. We used a Cormack–Jolly–Seber approach to estimate survival of breeding hawks, and a stochastic, stage-based matrix to estimate λ. Despite the urban-related disease, the estimate of λ indicated that the area does not function as a habitat sink for Cooper’s hawks (= 1.11 ± 0.047; P = 0.0073 for the null of λ ≤ 1). Because data required to reliably identify habitat sinks are extensive and difficult to acquire, we suggest that the concept of habitat sinks be applied cautiously until substantiated with reliable empirical evidence.  相似文献

This paper draws on a ‘palette’ of interdisciplinary methods to explore young people’s alcohol consumption practices and experiences in the hyper-diverse suburban locations of Chorlton and Wythenshawe, Manchester, UK. This paper contributes to literature on the emerging theme of hyper-diversity by exposing the heterogeneity of young people’s drinking experiences, with a focus on bars, pubs, streets and parks. I demonstrate how young people’s inclusion and exclusion from such spaces is bound up with the traditional identity markers of age, gender and class, alongside more performative, embodied, emotional and affective aspects; for instance, the atmospheres, smell and soundscapes of particular drinking spaces. More than this, the paper enhances understandings of hyper-diversity by elucidating the ways in which young people’s everynight alcohol-related mobilities and diversity interpenetrate each other. Through analysing young people’s alcohol consumption practices and experiences, I show how young people are hyper-diverse in terms of their alcohol-related lifestyles, attitudes, and activities.  相似文献

In this article, the role of e-technology is explored, with an emphasis on the advantages and disadvantages of its use for health care and mental health research. E-technology is broadly understood to include the Internet and related information technologies, and in recent years, its use has grown rapidly. The Internet is a major source of health information, and there is potential to deliver enhanced services through this medium. In addition, e-technology's role in future mental health service delivery and research will continue to expand as increased numbers of consumers, caregivers, health professionals, and the general population go online, particularly as the technology is refined and made even more user friendly.  相似文献

Abstract

Studies of disability movements have centred on exploring how movements have emerged and how their strategies have been devised to effectively advocate for the rights of the people with disabilities they represent. However, little attention has been focused on examining their organisational contexts and how they shape ideologies and choice of strategies, which have implications for the success of their advocacy endeavours. This article seeks to contribute to knowledge in this area by studying the case of a disabled people’s organisation in Cambodia. The resource dependency of disabled people’s organisations on international development partners results in their ideologies and strategies being driven by the latter. This has not only fragmented their resources, but also made their endeavours less relevant to the needs of people with disabilities. This may act to prevent such organisations from building a common ground for collective action, and from effectively pressing for social change.  相似文献

The current qualitative study involved in-depth semistructured interviews with parents whose children had been taken into custody. Their initial emotional reactions, cognitive processing, and behavioral responses to their child’s detention were examined. Five themes emerged from the data: (1) Parents try to defer immediate interactions with the child rather than react out of emotion; (2) Parents feel anger toward their child, but disappointment and shock are more strongly expressed emotional responses; (3) Parents do not accept the behavior but do not reject their child; (4) Police behaviors communicate the seriousness of the act; and (5) The entire family suffers consequences from the child’s act. Findings highlight the experiences of the parents as they interacted with the juvenile justice system.  相似文献

Attrition represents a significant obstacle to overcome in any longitudinal research project. It is, perhaps, most keenly felt when the data collected are from a qualitative study, since, unlike quantitative longitudinal research, weighting factors cannot be applied to ‘correct’ for any biases in the achieved sample and even a small number of ‘lost’ respondents can equate to a large percentage of the original sample. It is perhaps because of qualitative longitudinal research’s (QLR) reliance on, generally speaking, smaller samples that few have been able to shed much light on which re-contacting procedures are associated with achieving higher rates of retention. In this article, using data from a fifth sweep of a larger but particularly challenging cohort of 199 former probationers, we explore the strategies which helped us maintain high levels of retention in a QLR study. The article contains many practical suggestions which others planning or undertaking similar studies may find useful.  相似文献

The research reported in this article investigates differential item functioning (DIF) in a listening comprehension test. The study explores the relationship between test-taker age and the items’ language domains across multiple test forms. The data comprise test-taker responses (N = 2861) to a total of 133 unique items, 46 items of which were shared across two or more forms. Twenty-one items demonstrated DIF. However, there was no pattern by language domain. Eleven items showing DIF appeared in more than one test form but DIF for these items occurred only once.  相似文献

Since 2000, youth cafes are accorded prominence in Irish youth policies and research. Youth cafes are drug and alcohol free recreational spaces and research shows that they impact positively on young people. Youth cafes are broadly similar to youth clubs, but they are less structured and are primarily youth-led spaces. This paper draws on qualitative materials from a national study of youth cafes in Ireland, arguing that young people’s perceptions of youth cafes are linked to individuality and connectedness. In this paper, we explore these discourses surrounding individuality and connection in detail and argue that youth work in the twenty-first century must simultaneously appeal to young people’s need for space to ‘be’ and to find themselves and provide a structure within which they can relate to others and wider society.  相似文献

This study extends research on financial inclusion by exploring the composition of financial services within communities. Using propensity-score-adjusted probit regression, we explored associations with savings account ownership using restriscted-access, cross-sectional data from the 2015 National Financial Capability Study with merged financial services and community demographic data. Living in communities where the density of banks and credit unions outnumbered that of alternative financial services was associated with lower-income households’ greater probability of owning a savings account, all else being equal. These results have implications for efforts aiming to improve financial inclusion.  相似文献
