Associations of neighbourhood greenness with physical and mental health : do walking, social coherence and local social interaction explain the relationships?

Background: Studies have shown associations between health indices and access to “green” environments but the underlying mechanisms of this association are not clear.

Objectives: To examine associations of perceived neighbourhood “greenness” with perceived physical and mental health and to investigate whether walking and social factors account for the relationships.

Methods: A mailed survey collected the following data from adults (n  =  1895) in Adelaide, Australia: physical and mental health scores (12-item short-form health survey); perceived neighbourhood greenness; walking for recreation and for transport; social coherence; local social interaction and sociodemographic variables.

Results: After adjusting for sociodemographic variables, those who perceived their neighbourhood as highly green had 1.37 and 1.60 times higher odds of better physical and mental health, respectively, compared with those who perceived the lowest greenness. Perceived greenness was also correlated with recreational walking and social factors. When walking for recreation and social factors were added to the regression models, recreational walking was a significant predictor of physical health; however, the association between greenness and physical health became non-significant. Recreational walking and social coherence were associated with mental health and the relationship between greenness and mental health remained significant.

Conclusions: Perceived neighbourhood greenness was more strongly associated with mental health than it was with physical health. Recreational walking seemed to explain the link between greenness and physical health, whereas the relationship between greenness and mental health was only partly accounted for by recreational walking and social coherence. The restorative effects of natural environments may be involved in the residual association of this latter relationship.

Sexual practices and the duration of last heterosexual encounter : findings from the Australian longitudinal study of health and relationships

This study investigated the association between sexual practices and duration of a sexual encounter. Using data from a population-based computer-assisted telephone survey of 8,656 Australians aged 16 to 64 years, four distinct patterns of sexual practices among respondents were found: “basic sexual encounter” (involving mainly kissing, cuddling, stroking one's partner and being stroked, and vaginal intercourse), “basic sexual encounter plus oral sex,” “all assessed sexual practices” (all sexual behaviors included in the survey), and “mainly vaginal intercourse” (characterized by lower levels of kissing, cuddling, and stroking). For both men and women, respondents classified in the basic sexual encounter plus oral sex, and all assessed sexual practices clusters reported significantly longer durations than those in the basic sexual encounter group, whereas respondents in the mainly vaginal intercourse cluster reported shorter durations. These differences were found even after allowing for demographic differences in sexual duration—specifically, age and partner type of the most recent opposite-sex partner. These findings add to the understanding of what typically happens in a sexual encounter. Overall, longer sexual encounters appear to be associated with the inclusion of the least common sexual practices—namely, oral sex and self-stimulation.

Distribution of an alien aquatic snail in relation to flow variability, human activities and water quality

1. Disturbance and anthropogenic land use changes are usually considered to be key factors facilitating biological invasions. However, specific comparisons of invasion success between sites affected to different degrees by these factors are rare.

2. In this study we related the large-scale distribution of the invading New Zealand mud snail (Potamopyrgus antipodarum) in southern Victorian streams, Australia, to anthropogenic land use, flow variability, water quality and distance from the site to the sea along the stream channel.

3. The presence of P. antipodarum was positively related to an index of flow-driven disturbance, the coefficient of variability of mean daily flows for the year prior to the study.

4. Furthermore, we found that the invader was more likely to occur at sites with multiple land uses in the catchment, in the forms of grazing, forestry and anthropogenic developments (e.g. towns and dams), compared with sites with low-impact activities in the catchment. However, this relationship was confounded by a higher likelihood of finding this snail in lowland sites close to the sea.

5. We conclude that P. antipodarum could potentially be found worldwide at sites with similar ecological characteristics. We hypothesise that its success as an invader may be related to an ability to quickly re-colonise denuded areas and that population abundances may respond to increased food resources. Disturbances could facilitate this invader by creating spaces for colonisation (e.g. a possible consequence of floods) or changing resource levels (e.g. increased nutrient levels in streams with intense human land use in their catchments).

Distribution and abundance of human-specific Bacteroides and relation to traditional indicators in an urban tropical catchment

The study goals were to determine the relationship between faecal indicator bacteria (FIB), the HF183 marker and land use, and the phylogenetic diversity of HF183 marker sequences in a tropical urban watershed

Privatising human rights: what happens to the state`s human rights duties when services are privatised?

Human rights law has traditionally focused on the obligations of states in fulfilment of human rights - how a state-focused approach fits in a world where social services are frequently privatised or contracted out - examples of social service provision, health, education and prisons, and inquiries into the obligations of the state and the private operators in relation to these services - private providers of social services have certain human rights obligations within their respective spheres of activity - the state retains an obligation to guarantee the protection and realisation of human rights of everyone under its jurisdiction, regardless of the character of the service provider.

Holding the purse strings : the continuing evolution of human rights law and the potential liability of the finance industry for human rights abuses

While the responsibility of States and, in more recent times, corporations, has been thoroughly discussed in relation to human right~, a new stage of evolution may be emerging in relation to the liability of the financial backers of an enterprise that is accused of human rights abuses. This article considers the basis in international law for such emerging liability and examines some of the legal avenues used in recent domestic litigation against financial institutions. The article concludes by examining some of the relevant instruments of 'soft' international law and notes that although there is little in the way of concrete legislation or judicial precedent that would hold financial institutions responsible for the actions of those they invest in, the potential for the law to evolve in that direction is clear.

Encouraging critical reflections on privilege in social work and the human services

Critical reflection is promoted by many progressive social work writers as a process for facilitating practitioners' capacity to reflect upon their complicity in dominant power relations. However. the critical social work literature tends to focus attention on those who are disadvantaged. oppressed and excluded. Those who are privileged in relation to gender. class. race and sexuality etc are often ignored. Given that the flipside of oppression and social exclusion is privilege. the lack of critical reflection on the privileged side of social  divisions allows members of dominant groups to reinforce their dominance. This article interrogates the concept of privilege and examines how it is internalised in the psyches of members of dominant groups. After exploring the potential to undo privilege from within. the article encourages social work educators to engage in critical reflections about privilege when teaching social work students about social injustice and oppression.

Diesel exhaust particulate matter induces multinucleate cells and zinc transporter-dependent apoptosis in human airway cells

The cellular effects of biodiesel emissions particulate matter (BDEP) and petroleum diesel emissions particulate matter (PDEP) were compared using a human airway cell line, A549. At concentrations of 25 µg/ml, diesel particulate matter induced the formation of multinucleate cells. In cells treated with a mixture of 80% PDEP:20% BDEP, 52% of cells were multinucleate cells compared with only 16% of cells treated with 20% PDEP:80% BDEP with a background multinucleate rate of 7%. These results demonstrate a causal relation between the formation of multinucleate cells and exposure to exhaust particulate matter, in particular diesel exhaust. Exposure of A549 cells to PDEP induced apoptosis, seen by active caspase-3 expression and the presence of cleaved pancytokeratin. PDEP exhaust was a much stronger inducer of cellular death through apoptosis than BDEP. There was an eightfold increase in the expression of SLC30A3 (zinc transporter-3 or ZnT3) in cells exposed to 80% PDEP:20% BDEP compared to untreated cells. The increase in ZnT3 expression seen in apoptotic cells following PDEP suggests a role for this zinc transporter in the apoptotic pathway, possibly through controlling zinc fluxes. As exposure to diesel exhaust particles is associated with asthma and apoptosis in airway cells, diesel exhaust particles may directly contribute to asthma by inducing epithelial cell death through apoptotic pathway.

Human rights in Asia: A reassessment of the Asian values debate

"This book offers a critical reassessment of the "Asian values" debate, which dominated the human rights discourse in the late 1990s, and a reappraisal of the human rights situation in Asia since then. In this book Asian and non-Asian scholars contextualize the "Asian values" debate and examine in what ways the issues raised then continue to trouble Asian societies. Human rights are seen both in the context of political developments in individual Asian countries as well as in relation to global issues such as the Global War on Terror. The book challenges the reader to critically examine human rights rhetoric and practice both in Asia and globally."--BOOK JACKET.

The relationship between human beings and technological systems

By combining the ontological approaches to technology of Dessauer, Ortega y Gasset and Heidegger, with the psychology of Jung, the integrated and psycho-constructivist approach to technology demonstrates that the relationship between human beings and technological systems is a symptomatic, symbiotic and synchronistic factor of human well-being and adaption.

Uomo universale : the imaginary relation between body and mathematic(s) in architecture

What is the role of the human figure in the drawing of the uomo universale? Interlocked with the “master architect” as a constituent component of the canonical bodies of architecture, is the idea of the uomo universale, the universal man, an idea that was especially compelling to Renaissance masters. In contemporary social theory the uomo universale is read for its generic sense as the “universal subject”. Critical to this is a dialectical sense in which “man” confronts its non-neutral association with a gender specificity, either man or woman. This paper looks at the drawing and image of the uomo universale and explores the distinction between presence and representation, between the visibility of the image, its content and detail and the symbolic role of the image as constitutive of a canon of architecture. Though we are not meant to “see” the human figure as corporeal presence and rather focus our attention on the image as a geometric schema, my argument is that only through the figure is the uomo universale engendered as an image of the highest form of nature.

Nursing and justice as a basic human need

This paper explores the idea that justice is a basic human need akin to those famously depicted in Maslow’s hierarchy of human needs and, as such, warrants recognition as a core element in representative ideas about nursing. Early nurse theorists positioned the principles and practice of nursing as having their origins in ‘universal human needs’. The principle of deriving nursing care from human needs was thought to provide a guide not only for promoting health, but for preventing disease and illness. The nursing profession has had a longstanding commitment to social justice as a core professional value and ideal, obligating nurses to address the social conditions that undermine people’s health.The idea of justice as a universal human need per se and its possible relationship to people’s health outcomes has, however, not been considered. One reason for this is that justice in nursing discourse has more commonly been associated with law and ethics, and the legal and ethical responsibilities of nurses in relation to individualized patient care and, more recently, changing systems of care to improve health and health outcomes. Although this association is not incorrect, it is incomplete.A key aim of this paper is to redress this oversight and to encourage a broader conceptualization of justice as necessary for human survival, health and development, not merely as a professional value, or legal or ethical principle for guiding human conduct.

Piecing together the puzzle of graduate employment : factors that shape the graduate work expectations of human resource management students

Providing graduates with a set of skills and attributes relevant to their future employment remains a key topic in both higher education policy and research. This paper reports findings from a pilot study of human resource management (HRM) students' perceptions of the graduate work experience. Specifically, it focuses on how these perceptions are shaped, driven by a concern for the uncertainty - and even fear - expressed by the study's participants in relation to their future workplace experiences. The influences of three key factors in shaping participants' expectations are discussed: the graduate recruitment experience, previous work experiences and 'graduate work folklore' from the stories of family and friends. With these influences not always providing students with a realistic picture of their future work experience, we conclude that educators need to improve the opportunities for practical experience and industry knowledge through work placements, stronger links with industry and increased exposure to the practicalities of work within the curriculum.

Regulatory design strategies and enforcement approaches for research involving human embryos and cloning in Australia and the United Kingdom – time for a change.

This paper examines regulatory design strategies and enforcement approaches in the context of the UK and Australia’s regulation of research involving human embryos and cloning. The aim is to discuss current regulation in view of the impending review of the Research Involving Human Embryos Act 2002 (Cth) and the Prohibition of Human Reproductive Cloning Act 2002 (Cth). It is argued that the type of regulation used in relation to those who are licensed to research in Australia is unsuitable due to an over-emphasis on deterrence and the authoritarian approach taken by regulatory bureaucracies. The cost and efficiency of the current system is also questioned. The central thesis is that a co-regulatory system that combines the existing framework legislation with self-regulation should be adopted for licence holders. Such regulation of licence holders should include responsive regulatory strategies. ‘Command and control’ design strategies and deterrence approaches present in the current regulatory systems for breaches of legislation by non-licence holders and serious breaches by licence holders should be maintained.
