ABSTRACT

Work Integration Social Enterprises (WISE) offer supported work environments for people experiencing disadvantage, including people with disability. This paper reflects on a research project that is mapping the ways in which social enterprises in regional Australian cities produce wellbeing for their employees. Through supported employment programs, these organisations are transforming individual lives, helping to build a sense of self-worth and purpose, and increase individuals’ social skills and capacities. Many of the perceived benefits are associated with a belief in the innate good of paid work. Based upon interviews with employees in the social enterprises, it is apparent that the hopes attached to providing ‘meaningful work’ are considerable. At the same time social enterprises are taking on social responsibilities that were once provided by the state, while also selling their services as employers of disabled and disadvantaged members of society and maintaining commercial viability of the enterprise. Using feminist political economy alongside discussion of the distributive economy, this paper explores how contemporary policy conditions, productivist biases and normative discourses about the value of wage work inflect the forms of wellbeing that can be experienced by WISE workers.  相似文献

This paper focuses on the 'cultural turn' which has taken place in British and to a lesser extent North American and Australian human geography in the last decade. It begins by exploring what constitutes the cultural in what has been dubbed 'new cultural geography'. It then explores contemporary claims that cultural geography has eclipsed or marginalised social geography. The final section evaluates these claims about the demise of the social, arguing that the social has not been evacuated but rather has been redefined. While this paper tells a specific story about a particular tradition and geographical frame of reference, it nonetheless has wider relevance because it provides an example of the differential development of particular sub-disciplinary areas, of the way subdisciplinary knowledges shape each other, and of the way understandings of disciplinary trends are contested.  相似文献

The scientific environmental ethics plays a key role in the recognition of the human- environment interactions. Modern environmental ethics is the philosophical re-thinking of modern human race environmental behavior. The development of environmental ethics theory, as well as its application in reality, determines the viewpoints of environmental ethics. Sustainable development implies harmony on human-environment interactions and inter- generation responsibility, with emphasis on a harmonious relationship among population, resources, environment and development, so as to lay a sustainable and healthy foundation of resources and environment for future generations. The harmonious society construction in China that is raised by the Chinese central government should be covered by environmental ethics. The connotation of open environmental ethics includes a respect for nature, care for the individual human race, and respect for the development of future generations, which means giving consideration to natural values, individual and human race benefits and welfare across generations. The role of environmental ethics in regional development consists of cognition, criticism, education, inspiration, adjusting, legislation and promoting environmental regulations. The major problems in regional development are extensive resource exploration, fast population growth, irrational industrial structure, unfair welfare distribution and the twofold effects of science and technology development. The formulation of environmental ethics that aims at regional sustainable development, can not only harmonize the relationship of population, resource, environment and economic development, but also guide behavior selection, push social and political system transformation, strengthen the legal system, and raise environmental awareness of the public.  相似文献

Abstract:  To date, narrative correspondence has been relatively neglected as a geographical research method. This is particularly true within the subdiscipline of health geography. Drawing on the literature on narrative approaches, as well as a qualitative study of informal carers' experiences of transitions in the place of care for older people in New Zealand, this paper highlights the valuable insights this approach can offer into the interrelationship between people, place and care. More specifically, it explores how caring identities and care related behaviour are constructed and reconstructed over time and space.  相似文献

Positionality and Praxis: Fieldwork Experiences in Rural India   总被引:1,自引:0,他引:1  
This paper provides a reflexive account of conducting fieldwork as a graduate student in the Sunderban area of West Bengal state, India, in the mid‐1990s. Reflecting on my personal experiences of research in a setting that was simultaneously familiar and foreign, I use frames of positionality to understand the impact of explicit and implied power structures on the research process, the relationships between the researcher and those researched, and the transfer of knowledge. This paper argues that the multiple subject positions and identities of both scholar and subjects as presented in the field vary with setting, and that these positionalities affect access to informants, the tenor and outcomes of encounters, and knowledge production. While self‐reflexivity is endorsed as a strategy for critically informed research, active measures such as openness about the agenda and activities undertaken, self‐disclosure, making conscious accommodations for the research subject's work schedule and time constraints, mutual sharing of information, and explicit recognition of the research subjects' expertise through lived experiences are proposed as strategies for equalising the power balance between scholar and subject.  相似文献

The Government of India considers prenatal care programs as a priority activity for promoting safe motherhood and child survival. It relies heavily on electronic mass media, including radio, television, and cinema to educate mothers—two‐thirds of whom are illiterate—about prenatal check‐ups and timing, iron prophylaxis, and tetanus toxoid injections. This study evaluated the effect of mothers' exposure to electronic mass media on knowledge and use of prenatal care services, using data from India's 1998–1999 National Family Health Survey. Multivariate logistic regressions were used to estimate the effects of media exposure by calculating odds ratios of each of the four response variables (complete prenatal care services, prenatal check‐ups, tetanus toxoid injections, and iron prophylaxes) for exposure to mass media. The results indicated that exposure to mass media is related to the use of prenatal care services even when other likely causes of the relationships are statistically controlled at their mean. The effect also showed a north‐south divide among the Indian States, being stronger in northern states as compared with southern states.  相似文献

Emerging organic contaminants (EOCs) in New Zealand freshwaters are not well documented for regulatory assessments. We collected water and sediment samples for measurement of 26 EOC compound concentrations at four waterways within the city of Dunedin (Otago province). Compounds measured ranged from stimulants and depressants to pain-killers and insect repellants. Sampling was conducted before and after the student ‘Orientation Week’ at the University of Otago. Most compounds were below detection limits in all samples. However, caffeine, carbamazepine, cotinine and DEET were all measured at concentrations above detection limits. In general, concentrations of EOC compounds were ~20% higher following the influx of students to the University though student effects varied by site and additional sampling is needed to better assess temporal variation in concentrations. These data indicate that some EOCs are present in New Zealand freshwater ecosystems.  相似文献

Over the last decade a range of social banks and Community Development Finance Initiatives (CDFIs) have developed a social investment sector in the UK. Some of these organisations emphasise their belief in partnership, association, reconnecting and re-humanising the relationship between investors with borrowers in order to reap social returns. ‘Ethical’ investors are encouraged to take sub-market returns on their investments in order for surpluses to be distributed to the organisations’ beneficiaries. Some key theoretical and political questions include: how are investors enrolled in these initiatives? What discourses of ethics are constructed and how do investors relate to them? How do these discourses relate to debates in geography revolving around ‘caring at a distance’? Drawing on work on the Charity Bank and the Industrial Common Ownership Fund (ICOF), this paper analyses how these discourses are constructed and mediates the relationship between investors and borrowers. It explores stakeholders both investors’ and borrowers’ perceptions of these activities as well as the way investors construct their own reasons for investing.  相似文献
