A conceptual framework for the study of human ecosystems in urban areas

The need for integrated concepts, capable of satisfying natural and social scientists and supporting integrated research, motivates a conceptual framework for understanding the role of humans in ecosystems. The question is how to add humans to the ecological models used to understand urban ecosystems. The ecosystem concept can serve as the basis, but specific social attributes of humans and their institutions must be added. Learning and feedback between the human and natural components of urban ecosystems are key attributes of the integrated model. Parallels with familiar ecological approaches can help in understanding the ecology of urban ecosystems. These include the role of spatial heterogeneity and organizational hierarchies in both the social and natural components of urban ecosystems. Although urban watersheds are commonly highly altered, the watershed approach can serve as a spatial basis for organizing comparative studies of ecosystems exhibiting differing degrees of urbanization. The watershed concept can also spatially organize the hierarchically scaled linkages by which the integrated human ecosystem model can be applied. The study of urban ecosystems is a relatively new field, and the questions suggested by the integrated framework can be used to frame ecosystem research in and associated with urban and metropolitan areas.     

A production engineering approach to robot selection

The successful introduction of robots into an industrial enterprise means real commitment, engineering support, and detailed involvement in the planning of an integrated manufacturing system. In particular, the production engineer is clearly seen in this context to be the system designer. He must therefore be in a position to specify the performance of all man and machine components within the system such that productivity is maximised. Robot types are reviewed, and analogies between man and machine are used to introduce the RTM concept. Finally, a simple method is given for estimating robot throughput times from elementary velocity profiles. The fall-off in throughput due to the effect of many small robot movements is emphasised.     

Implications of government funding of advocacy for third‐sector independence and exploration of alternative advocacy funding models

This paper examines the effect of funding contracts on the capacity of third‐sector organizations to effectively advocate. The relationship is not simple or obvious, with some organizations reporting 'mature relationships' with particular (state) departments, and others reporting difficulty with state or federal government jurisdictions. The paper spells out the negative effects of conflating service funding and advocacy. The paper concludes by exploring alternative institutional arrangements for the resourcing of advocacy including the establishment of a Public Interest Fund administered independently of any government department, one not requiring specific service contracts but rather evidence that it is advocating for the broader public good.     

1 The Fundamental Agency Problem and Its Mitigation

A central tenet of agency theory is that there is potential for mischief when the interests of owners and managers diverge. In those circumstances, and for a variety of reasons, managers may be able to exact higher rents than are reasonable or than the owners of the firm would otherwise accord them. While that foundational element of agency theory is secure, other elements derived directly from agency theory are far less settled. Indeed, even after some 75 years of conceptualization and empirical research, the three principal approaches that have long been proposed to mitigate the fundamental agency problem remain contentious. Accordingly, we provide a review of the fundamental agency problem and its mitigation through independence, equity, and the market for corporate control.     

Disability and mortgage default: an Australian study

Debates on human rights and discrimination regarding housing and disability need to emphasise community care and inclusion as principles for improving policy. A qualitative study of Australian mortgage default reveals special difficulties for households with a member with a disability; that is, illness, impairment or injury limiting everyday activities and enduring for several months. Interviews showed that such households adopted similar strategies to other mortgagors with serious financial difficulties but tended to have fewer and less attractive options. Given the crisis in Australian disability welfare services and the 2010–2011 Productivity Commission inquiry recommending major reforms, these findings can inform policy.

“Who's afraid?”: Attitudes of midwives to the use of information and communication technologies (ICTs) for delivery of pregnancy-related health information

BackgroundUsage rates for information and communication technologies (ICTs) in healthcare have been increasing in recent years, but often lag behind general usage rates for populations as a whole. Research into such differential rates of ICT use across different segments of the population has identified a number of possible causal factors that limit usage.AimThe research investigated midwives’ attitudes and experiences of ICT use to identify potential causal factors that encourage or inhibit their usage in antenatal care.MethodsSemi-structured interviews, focus groups and short surveys were conducted with midwives who provide antenatal education at an Australian metropolitan hospital. Thematic and statistical analyses were used to interpret the data.FindingsAlthough midwives recognised the potential benefits of using ICTs to deliver pregnancy-related health information many had reservations about their use in everyday work. These reservations centred on lack of training in use of ICTs, the perceived legal risks associated with social media, potential violations of patient privacy, misdiagnosis and misunderstandings between midwife and client.ConclusionMidwives face a number of barriers to effective use of ICTs in healthcare including material access, skills access, usage access and motivational access. Motivational access appears to be a key concern due to the high perception of risk associated with social media in particular. Reducing the motivational barriers through a range of interventions with midwifery staff may assist in overcoming other barriers to ICT use in antenatal care. Further research is required to determine whether these findings are generalisable to other healthcare contexts.     

Creativity, Habit, and the Social Products of Creative Action: Revising Joas, Incorporating Bourdieu

Hans Joas's The Creativity of Action (1996) posits that conceiving of all action as fundamentally creative would overcome problems inherent in rational and normative theories of action and would provide an alternative basis for action‐based theories of macrosociological phenomena. Joas conceives of creativity as a response to the frustration of "prereflective aspirations," which necessitates innovative adjustment to reestablish habitual intentions. This conceptualization creates an unsupportable duality between habitual action and creativity that neglects other possible sources of creative action, including habit itself. Combining strengths from Bourdieu's concept of habitus, creativity can be redefined as the necessary adaption of habitual practices to specific contexts of action. Creative action continually introduces novel possibilities in practical action and provokes a variety of social responses to its products. This revised concept of creativity overcomes the dichotomy presented by Joas, identifies a microsocial source of innovation in creative action, and calls attention to patterns of creative authority in society at large .
