Burnout in physicians : a case for peer-support

Background: It is well documented that doctors experience a high level of stress in their profession, and that this can lead to physical, psychological, and emotional harm, in particular, burnout. Overseas (especially in the UK and USA), research investigating the levels of stress, burnout, and associated psychiatric morbidity in health professionals, across many specialities, has been carried out with a view to prevention of these adverse outcomes.

Aims: To assess the level of burnout in a sample of New Zealand physicians, the associated work and personal characteristics, and the need for development of a support peer supervision or support system.

Methods: Questionnaires that measured a number of work and personal characteristics, including the Maslach Burnout Inventory, the General Health Questionnaire, and additional questions regarding mistakes, and need for support, were sent to 83 physicians in the Waikato and Bay of Plenty areas. Analysis involved descriptive statistics, with t-tests for comparison with other studies, Pearson Product-Moment correlations between variables and analysis of variance where appropriate.

Results: Of the 50 respondents, 28% experienced high levels of two or three aspects of burnout (emotional exhaustion, depersonalization, low personal accomplishment). Emotional exhaustion correlated with a greater need for support. Most respondents favoured a one-to-one support system.

Conclusion: This study highlights the presence of significant workplace difficulties for physicians and the need to develop a preventative support system for the protection of physicians and the patients in their care.

Little boys : the potency of peer culture in shaping masculinities

This study explores the peer group understandings of five male friends between the ages of six and eight years and seeks to examine the ways in which the group’s social dynamics interact to define, regulate and maintain dominant and collective understandings of masculinities. Within a self-selected affinity context, and drawing on their lived and imagined experiences, the boys’ enact and interpret their social worlds. Adopting the principles of ethnography within a framework of feminist poststructuralism and drawing on theories of ‘groupness’ and gender(ed) embodiment, the boys’ understandings of masculinities are captured and interpreted. The key analytic foci are directed towards examining the role of power in the social production of collective schoolboy knowledges, and understanding the processes through which boys subjectify and are subjectified, through social but also bodily discourses. The boys’ constructions of peer group masculinities are (re)presented through a narrative methodology which foregrounds my interpretation of the group’s personal and social relevances and seeks to be inductive in ways that ‘bring to life’ the boys’ stories. The study illuminates the potency of peer culture in shaping and regulating the boys’ dominant understandings of masculinity. Within this culture strong essentialist and hierarchical values are imported to support a range of gender(ed) and sexual dualisms. Here patriarchal adult culture is regularly mimicked and distorted. Underpinned by constructions of ‘femininity’ as the negative ‘other’, dominant masculinities are embodied, cultivated and championed through physical dominance, physical risk, aggression and violence. Through feminist poststructural analysis which enables a theorising of the boys’ subjectivities as fluid, tenuous and often characterised by contradiction and resistance, there exists a potential for interrupting and re-working particular masculinities. Within this framework, more affirmative but equally legitimate understandings and embodiments can be explored. The study presents a warrant for working with early childhood affinity groups to disrupt and contest the dominance and hierarchy of peer culture in an effort to counter-act broader gendered and heterosexist global, state and institutional structures. Framing these assertions is an understanding of the peer context as not only self-limiting and productive of hierarchies, but enabling and generative of affirmative subjectivities.

Tutor and teacher timescapes : lessons from a home-school partnership

A partnership project was developed in which parents volunteered to support teachers
in training years 1-3 children in computer skills at a primary school in a small, low
socio-economic community. This article identifies the ways teachers and the ‘tutors’
(as the volunteers were called) understood the value of the project. ‘Being a teacher’
and ‘being a volunteer’ were structured by different forms of social engagement,
which in turn influenced the ways individuals were able to work with each other in
collaborative processes. We argue that the discursive practices encoded in homeschool-
community partnership rhetoric represent ruling-class ways of organising and
networking that may be incompatible with those of people from low socio-economic
backgrounds. When such volunteers work in schools their attendance may be sporadic
and short-term whereas teachers would like ‘reliable’ ongoing commitment. This
mismatch wrought of teachers’ and volunteers’ differing everyday realities needs to be
understood before useful models for partnerships in disadvantaged communities may
be realised.

A peer-focused depression prevention program for preadolescent children

This thesis develops and evaluates the effectiveness of a peer-focused cognitive-behavioural depression prevention program (Kool Kids Program [KKP]) for preadolescent children. It was demonstrated that the KKP was partially effective at reducing depressive symptoms and improving the psychosocial functioning of preadolescent children up to 6 months following intervention. The professional portfolio discusses the unique role of clinical psychologists within multidisciplinary teams and the contribution they make to interdisciplinary collaboration. Four case studies are presented.

Exploring positive cross-gender peer relations : Year 10 students' perspectives on cross-gender friendships

Much of the current academic and policy literature on gender and inclusive education calls for schools and teachers to move towards understanding gender as a multidimensional process of negotiated social relations that is informed by a range of discursive practicesbut how students themselves can conceptualize gender relations in these ways is under researched. This paper reports on an aspect of an exploratory study that had as its focus students' perceptions of cross-cultural and cross-gender friendships. This project, funded by a small Australian Research Council grant from La Trobe University, began with surveys of Year 10 students at two schools who have previously participated in gender reform projects. Those students who indicated they had cross-category friendships were then interviewed to elicit narratives that depict their perspectives on these friendships.

Multi-level virtual ring : a foundation network architecture to support peer-to-peer application in wireless sensor network

Two main problems prevent the deployment of peer-to-peer application in a wireless sensor network: the index table, which should be distributed stored rather than uses a central server as the director; the unique node identifier, which cannot use the global addresses. This paper presents a multi-level virtual ring (MVR) structure to solve these two problems.

The index table in MVR is distributed stored by using the DHT technique. MVR is constructed decentralized and runs on mobile nodes themselves, requiring no central server or interruption. Naming system in MVR uses natural names rather than global addresses to identify sensor nodes. The MVR can route directly on the name identifiers of the sensor nodes without being aware the location. Some sensor nodes are selected as the backbone nodes by the backbone selection algorithm and are placed on the different levels of the virtual rings. MVR hashes nodes’ identifiers on the virtual ring, and stores them at the backbone nodes. Furthermore, MVR adopts cross-level routing to improve the routing efficiency.

Experiments using ns2 simulator for up to 200 nodes show that the storage and bandwidth requirements of MVR grow slowly with the size of the network. Furthermore, MVR has demonstrated as self-administrating, fault-tolerant, and resilient under the different workloads.

An examination of the role of the e-tutor

As online learning environments continue to evolve, both teachers and students need to adapt to make the most of opportunities afforded by these environments for teaching and learning. The focus of this paper is on the changing role undertaken by tutors in online learning environments. We present a brief review of the current perspectives on the roles and responsibilities suggested for the e-tutor for effective teaching, and then report on a study where roles of e-tutors in a large wholly online unit were examined. The study supports the view that although the role of the e-tutor is similar to that of the face to face tutor in some respects, there are sufficient differences to make e-tutoring challenging to those who have not undertaken such online activities previously. Ongoing professional development is required to meet the changing demands of the technological environment, as well as the changing needs of
students.

Sharable file searching in unstructured peer-to-peer systems

The existing sharable file searching methods have at least one of the following disadvantages: (1) they are applicable only to certain topology patterns, (2) suffer single point failure, or (3) incur prohibitive maintenance cost. These drawbacks prevent their effective application in unstructured Peer-to-peer (P2P) systems (where the system topologies are changed time to time due to peers' frequently entering and leaving the systems), despite the considerable success of sharing file search in conventional peer-to-peer systems. Motivated by this, we develop several fully dynamic algorithms for searching sharing files in unstructured peer to peer systems. Our solutions can handle any topology pattern with small search time and computational overhead. We also present an in-depth analysis that provides valuable insight into the characteristics of alternative effective search strategies and leads to precision guarantees. Extensive experiments validate our theoretical findings and demonstrate the efficiency of our techniques in practice.
