The National Climate change Adaptation Research Plan: Indigenous Communities (2011) highlighted that research on Indigenous communities and climate change, including the variables of impacts, vulnerability and adaptive capacity and adaptation has been limited. While most research has focused on identifying the biophysical impacts of climate change, a minority of studies have considered the Indigenous knowledge and peoples whom continue to reside in Australia and care for; ‘country’;. The report concluded that “there is a need for research that expands knowledge about these and other dimensions of Indigenous adaptation to climate change.“ This paper reviews work in progress on a NCCARF funded research project that is seeking to investigate select coastal urban and per-urban Indigenous community vulnerability to, and capacity for climate change adaptation. Working collaboratively with Indigenous communities resident in Adelaide, Heywood/Portland, Mornington Peninsula, Stradbroke Island and Brisbane, it seeks to explore and articulate strategies that enhance Indigenous capacity to climate change including possible protocols, frameworks, processes and procedures that may lead directly to a more informed appreciation of what is transpiring around Australia’s coastal per-urban regions for their Indigenous communities who still hold strong bonds and responsibilities to their ‘country’.

Over the last two decades, the concept of resilience has become the focus of a growing body of gerontological research. However, there is a dearth of qualitative research that explores how socio-economic and socio-cultural factors shape older people's resilience. This study addresses this gap and explores the concept of resilience through the lens of 25 Australians from a variety of backgrounds, investigating the resilience strategies they employed in the face of different challenging life events. A qualitative narrative methodology involving one focus group and semi-structured interviews was employed. A stratified convenience sample of 34 people aged 60 and over participated in semi-structured interviews between 2009 and 2011. The study describes the meaning participants assigned to the term resilience, and focuses on the range of resilience responses and strategies they employed, bringing to light some key commonalities and differences. The study's findings suggest that access to economic and cultural resources and the nature of the adversity older people face can shape and limit their resilience strategies. The article outlines how the concept of resilience could be incorporated into aged care practice and argues that resilience-focused interventions that potentially broaden the resilience repertoire of older people should be explored within an aged care context.

To understand whether prolonged confinement results in reductions in physical activity and adaptation in the musculoskeletal system, six subjects were measured during 520 d isolation in the Mars500 study. We tested the hypothesis that physical activity reduces in prolonged confinement and that this would be associated with decrements of neuromuscular performance. Physical activity, as measured by average acceleration of the body's center of mass ("activity temperature") using the actibelt® device, decreased progressively over the course of isolation (p<0.00001). Concurrently, countermovement jump power and single-leg hop force decreased during isolation (p<0.001) whilst grip force did not change (p≥0.14). Similar to other models of inactivity, greater decrements of neuromuscular performance occurred in the lower-limb than in the upper-limb. Subject motivational state increased non-significantly (p = 0.20) during isolation, suggesting reductions in lower-limb neuromuscular performance were unrelated to motivation. Overall, we conclude that prolonged confinement is a form of physical inactivity and is associated with adaptation in the neuromuscular system.

In the context of emergency services and first responders (i.e. military), the ability to select personnel who have the innate ability to work well in highly charged environments would be advantageous. While there have been some efforts to explore the relationship between personality traits and physiological reactivity in the context of the emergency services, differences in stress responses between civilians and military personnel have not yet been investigated. Therefore the aim of the current study was to examine the relationship between personality, resilience and physiological stress responses. Fifteen civilians and 16 military personnel completed online personality (IPIP) and resilience (CD-RISC) inventories prior to commencing the experimental component of the study. The Mannheim Multi-component Stress Test (MMST) which utilises cognitive, audio, visual and motivational components was employed to elicit an acute stress response. Measures of correct responses and reaction time were sampled during the MMST. Prior to and following exposure to the MMST, positive and negative affect were measured (PANAS), and heart rate was sampled continuously across the study period. Results indicated that Military participants rated significantly lower than civilians on neuroticism; however there were no differences between groups for resilience or any of the other personality traits. Military participants displayed less emotional reactivity and less negative affect following the MMST testing period, and appeared to perform better on the MMST when compared to the civilian sample. However, there was no significant difference in heart rate measures between groups. Collectively, these results provide support for the broaden and buildhypothesis and the transactional stress theory. The results also build on previous empirical stress literature and support the effectiveness of the MMST in laboratory induced stress. Suggestions for future research in the area of resiliency and stress will be discussed. From an applied context, further research in this area may assist in military recruitment processes to place individuals in roles to which they are most suited within the Defence Force.

Compassion fatigue is a term used to describe behaviour and emotions experienced by those who help people who have experienced trauma. It is viewed as a potential consequence of stress related to such exposure and is understood to be influenced by the practitioner’s empathic response. The aims of this study were to obtain greater understanding of social workers experience of working with distressed clients; examine what develops personal, professional and organisational resilience; and explore ways in which workers can be better protected from compassion fatigue. The research design was qualitative using semi-structured interviews involving six social workers presently working with distressed clients or clients known to have experienced distress. Four major themes were identified using thematic analysis: (i) the complexities of social work, (ii) supportive and unsupportive contexts, (iii) promoting personal well-being/selfprotection and (iv) resilience as a changing systemic and complex process. The findings provide important insights into the participants’ experiences of working with distressed clients and, more specifically, their experience of compassion fatigue and stories of resilience. The research provides clear direction for future research at organisational, educational and interpersonal levels.

Energy and communication infrastructure for disaster resilience in rural and regional Australia, Regional Studies. Australia's rural and regional areas are prone to frequent natural disasters with extensive socio-economic impacts. Resultant damage to large-grid energy and communication networks can lead to widespread, lengthy outages, signalling the need for alternative infrastructure developments to aid disaster risk reduction and resilience-building (DRRR). Distributed smart renewable energy micro-grid systems can mitigate adverse impacts through outage prevention and rapid service restoration, increase rural and regional resilience, and offer communities opportunities for socio-economic development. However, renewable energy and digital communications policy uncertainty currently adversely affects disaster preparedness and investment in alternative infrastructure, undermining rural and regional futures.

■ Human well-being has several key components: the basic material needs for a good life, freedom and choice, health, good social relations, and personal security. Well-being exists on a continuum with poverty, which has been defined as"pronounced deprivation in well-being."
■ How well-being and ill-being, or poverty, are expressed and experienced is context- and situation-dependent, reflecting local social and personal factors such as geography, ecology, age, gender,and culture.These concepts are complex and value-laden.
Ecosystems are essential for human well-being through their provisioning, regulating, cultural, and supporting services. Evidence in recent decades of escalating human impacts. on ecological systems worldwide raises concerns about the consequences of ecosystem changes for human well-being.
■ Human well-being can be enhanced through sustainable human interaction with ecosystems with the support of appropriate instruments, institutions, organizations, and technology. creation of these through participation and transparency may contribute to people's freedoms and choices and to increased economic, social,and ecological security.
■ Some believe that the problems from the depletion and degradation of ecological capital can be largely overcome by the substitution of physical and human capital. Others believe that there are more significant limits to such substitutions.The scope for substitutions varies by socioeconomic status.
■ We identify direct and indirect pathways between ecosystem change and human well-being,whether it be positive or negative.lndirect effects are characterized by more complex webs of causation, involving social, economic, and political threads. Threshold points exist beyond which rapid changes to human well-being can occur.
■ Indigent poorly resourced, and otherwise disadvantaged communities are generally the most vulnerable to adverse ecosystem change. Spirals, both positive and negative, can occur for any population, but the poor are more vulnerable.      
■ Functioning institutions are vital to enable equitable access to ecosystem services. lnstitutions sometimes fail or remain undeveloped because of powerful individuals or groups. Bodies that mediate the distribution of goods and services may also be appropriated for the benefit of powerful minorities.
■ For poor people, the greatest gains in well-being will occur through more equitable and secure access to ecosystem services. In the long run, the rich can contribute greatly to human well-being by reducing their substantial impacts on ecosystems and by facilitating greater access to ecosystem services by the poor.
■ We argue ecological security warrants recognition as a sixth freedom of equal weight with participative freedom, economic   facilities, social opportunities, transparency guarantees, and protective security.

Patellar tendinopathy, a common condition in sport, can be recurrent and resistant to treatment, Risk factors include the level of training, biomechanics, and genetic factors. This review discusses several programs based on eccentric exercise and suggests principles for nonoperative treatment including improving shock absorption, load modification, and adaptation of the tendon to sporting stress. The level of pain that patients are asked to tolerate during tendon-exercise programs varies among programs, and it is unclear what level is optimal to stimulate tendon recovery. Rehabilitation presents several challenges: It can take a long time (3-12 months), exercise prescription in an athlete who is continuing to compete is not straightforward, and guidelines for treatment progression are poor, Nonoperative treatment can fail because of inappropriate exercise prescription and poor athlete compliance. If this occurs and surgical intervention is required, the athlete might still have an unpredictable outcome. Solutions to these problems require additional clinical research.

This paper proposes a hyperlink-based web page similarity measurement and two matrix-based hierarchical web page clustering algorithms. The web page similarity measurement incorporates hyperlink transitivity and page importance within the concerned web page space. One clustering algorithm takes cluster overlapping into account, another one does not. These algorithxms do not require predefined similarity thresholds for clustering, and are independent of the page order. The primary evaluations show the effectiveness of the proposed algorithms in clustering improvement.

Purpose – The purpose of this study is to examine empirically the relationship between psychic distance and adaptation of the retail offer across a range of countries.

Design/methodology/approach – Data were collected using a mail survey of randomly selected non-food retailers that operated stores in at least three foreign countries.

Findings – Findings of this study suggest that a substantial proportion of retail offer adaptation is explained by psychic distance. In particular, differences in market structure, business practices and language between the home and foreign market significantly increase the extent to which retailers adapt their offer.

Research limitations/implications – The research findings may be limited in terms of their generalisability across retail sectors, as the study focused on non-food retailers only.

Practical implications – These results have implications for researchers and managers in suggesting that we need to go beyond consumer behaviour differences to explain fully the degree to which international firms standardise or adapt their strategies in foreign markets.

Originality/value – Much of the existing research into standardisation and adaptation is limited in terms of geographic scope and a focus on the marketing strategies of manufacturing and export firms. Thus, this paper addresses a substantial gap in existing research by empirically examining the relationship between psychic distance and adaptation in a retail context and across a range of countries.

Background: Depression is becoming increasingly prevalent in young people and is occurring earlier. General practitioners are prescribing antidepressants more frequently for this group, yet they are usually not the answer to the problem. Objective: This article examines the increase in prevalence rates of childhood and adolescent depression. We draw on recent research into resilience and positive psychology to suggest guidelines for the GP in helping young people and their parents develop better coping skills in the short term, and greater resilience in the long term. Discussion: Resilience is the ability to bounce back after encountering difficulties, negative events, hard times or adversity and to be able to return to the original level of emotional wellbeing. It is the capacity to maintain a healthy and fulfilling life despite adversity. Young people who have the skills to be resilient have a lower likelihood of becoming depressed or suicidal and a higher likelihood of maintaining emotional wellbeing. Self efficacy, optimistic and helpful thinking, and maintaining a success orientation are all important skills in being resilient.

Currently, traditional development issues such as economic stagnation, poverty, hunger, and illness as well as newer challenges like environmental degradation and globalisation demand attention. Sustainable development, including its economic, environmental and social elements, is a key goal of decisionmakers. Optimal economic growth has also been a crucial goal of both development theorists and practitioners. This paper examines the conditions under which optimal growth might be sustainable, by assessing the costs and benefits of growth. Key environmental and social aspects are considered. The Ecol-Opt-Growth-1 model analyses economic–ecological interactions, including resource depletion, pollution, irreversibility, other environmental effects, and uncertainty. It addresses some important issues, including savings, investment, technical progress, substitutability of productive factors, intergenerational efficiency, equity, and policies to make economic growth more sustainable—a basic element of the sustainomics framework. The empirical results support growing concerns that costs of growth may outweigh its benefits, resulting in unsustainability. Basically, in a wide range of circumstances, long term economic growth is unsustainable due to increasing environmental damage. Nevertheless, the model has many options that can be explored by policy makers, to make the development path more sustainable, as advocated by sustainomics. One example suggests that government supported abatement programs are needed to move towards sustainable development, since the model runs without abatement were infeasible. The optimal rate of abatement increases over time. Abatement of pollution is necessary to improve ecosystem viability and increase sustainability. Further research is necessary to seek conditions under which alternative economic growth paths are likely to become sustainable.

The potential for resilient behaviors and emotional intelligence involves an interplay between the individual and his or her broader environment. Studies that have examined resilience explore factors or characteristics that assist individuals to thrive from and in adversity. These protective factors are part of an individual’s general makeup. Some of these factors are considered genetic, such as a personality that is outgoing and social; however, many protective behaviors can be learned. Coping in the face of adversity involves emotional intelligence and resilience, both of which can be developed through support and education. In this context, fostering resilience and emotional intelligence has the potential to improve clinical outcomes for mental health consumers.

Recent political, economic and social trends pose threats to the sustainability both of ecosystems and of human health. Australia’s environmental management record is poor, and while by international standards Australians enjoy good health, this is variable (AIHW, 2000). Within developed nations, heart disease, depression, alcohol dependence and stroke are major health issues (Mathers et al. 2002). In Australia, mental disorder is the number one contributor to the disease burden (Vos & Mathers 2000). Recent research has highlighted the role of social capital as a key determinant of health (Kawachi et al., 1997). Despite this, Putnam (1995) observes that social connectedness and civic engagement are in decline. People have less time for leisure and for volunteering, as many juggle paid work and caring for children. Anecdotal evidence suggests that engagement in civic environmentalism has human health benefits, relating to a combination of exposure to natural environments and increased social capital (Maller, Brown, Townsend & St. Leger, 2002). This link is supported by Furnass (1996) who defines well-being as including: satisfactory human relationships, meaningful occupation, opportunities for contact with nature, creative expression, and making a positive contribution to human society. Research conducted by Deakin University confirms the efficacy of linking people and places through civic environmentalism for addressing both ecosystem sustainability and human health and wellbeing. The research has included a pilot study to explore the human health benefits of membership of a local parkland ‘Friends’ group, and a more detailed follow-up study. The aims of the pilot study included:- To identify the range of motivations for joining the Friends group;- To document members’ perceptions of the benefits gained from membership of the group;- To assess the potential for Friends groups to be used as an ‘upstream’ health promotion measure.Face-to-face interviews were conducted with eleven members of a ‘Friends’ group in the eastern suburbs of Melbourne. Data was analysed thematically and key findings included:- Motivations: environmental; social; and pragmatic.- General benefits: community belonging; personal satisfaction; learning opportunities; physical activity; and better environment.- Health benefits: physical health; mental health; and social support. There was unanimous support for the use of ‘Friends’ groups as a tool for health promotion.The follow-up study, in the western suburbs of Melbourne, expanded on the pilot study by measuring the group’s social capital and by collecting self-report data on levels of health service usage. Data was collected through face-to-face interviews and a questionnaire. The findings were similar to the pilot study in relation to the motivations, benefits and the health promotion potential of such groups. However, health service usage data highlighted an apparent anomaly: while respondents perceived significant health benefits, some were nevertheless utilising health services at a relatively high level. This poses some questions requiring further exploration: Is this due to the poorer baseline health of the high health service usage members compared with their fellow members? Does involvement in the group offer health benefits that enable people who would otherwise be too unhealthy to participate in community groups to continue such involvement?If this is the case, then we may do well to look to locally-based mechanisms for promoting ecological sustainability as a tool also for promoting human health. Instead of prescribing a pill, connecting people and places through engagement with a local friends group may address our health problems at the same time as addressing local environmental problems.
