(2001)Journal ArticleThree-dimensional numerical simulations of electron-beam-induced current (EBIC) near a vertical silicon grain boundary are demonstrated. They are compared with an analytical model which excludes the effect of carrier generation other than in the bulk base region of a solar cell structure. We demonstrate that in a wide range of solar cell structures recombination in the space charge region (SCR) significantly affects the EBIC results and hence needs to be included in the data evaluation. Apart from these findings, simulations of a realistic silicon solar cell structure (thick emitter, field-dependent mobility, etc.) are demonstrated.

(2009)Book ChapterSocial justice, and its application as a key social work value, has a particular resonance in the institutions of the criminal justice system. Promoting equality of access and resources, doing case work, and advocating for the rights of those who are imprisoned, is a complex task. Australian prisons are filled overwhelmingly with the poor, the socially impoverished, the geographically disadvantaged, the alienated and the dispossessed. Whilst this population is characterised by the social and economic disadvantage that is familiar to many social work settings, there are two complicating factors for social workers in Corrective Services. The first is that this population has also committed crime or at least has been accused of committing crime. The second is that prisons are closed institutions, where the internal workings are largely invisible to the general public. The life circumstances of prisoners (both inside and outside of prisons), even if extremely difficult, tend not to elicit a great deal of sympathy. In popular discourse, the fact and impact of the crime committed understandably overshadows the fact of the offender’s personal disadvantage. Because prisoners are out of sight, a simplistic and frequently dehumanising image of the prisoner is able to flourish, but of course it is entirely possible for someone to be both a decent individual, for example helping people in need, volunteering in emergencies, being a good friend, and a criminal. As Sotiri observed: "When I worked at [agency name] (a post-release NGO) we used to joke about how often we, as workers would say about our clients ‘he’s such a nice guy’. Because of course at some point many of our clients were not ‘nice guys’. Many had committed horrible crimes, or had at least acted ruthlessly and selfishly in their quest to obtain money and drugs." Although the fact of the crime is relevant, especially for some targeted rehabilitative work, working with this population requires a critical and holistic approach. This ensures that a client’s criminal behaviour does not entirely define who that person is. This is particularly important when working with a person leaving prison. Depending upon their role, social workers may need to consider not only the crime, but also the reasons why someone has committed crime, as well as the whole range of needs the person might have.

(2006)Journal ArticleUrban Aboriginal communities were asked about their experiences of human services. The misuse of Aboriginal liaison staff, the attitudes of staff and policy-makers, the invisibility of Aboriginal clients, poor communication, lack of access to services, client rights and lack of integration were raised. Respect for Aboriginal persons' social citizenship is discussed.

(2004)Journal ArticleBased on research by Dr Eileen Baldry, Dr Desmond McDonnell, Peter Maplestone and Manu Peeters. The project, conducted jointly by AHURI UNSW-UWS and RMIT-NATSZEM Research Centres, explored prisoners post-release housing circumstances and social integration and connections with re-offending. A sample of people being released from prison in NSW and Victoria over a 3 month period was interviewed and followed up at three, six and nine month intervals post-release.

(2008)Journal ArticlePurpose: Genetic testing for hereditary cancer facilitates medical management and improves health outcomes. Genetic testing is not currently available for prostate cancer, but trials are underway to investigate if antiandrogens and selenium have a preventive role for at-risk individuals. To inform future genetic counseling, we sought to understand the pre-existing beliefs and behaviors of men with a family history of prostate cancer and explore their intention to adopt possible preventive behaviors in response to test results. Methods: A survey was completed by 280 men (response: 59%). Results: The belief that diet influenced prostate cancer risk was held by 73% of participants, whereas 37% believed in medication/natural therapies. Thirty-nine percent reported at least one change to their diet, alcohol consumption, smoking, exercise patterns, vitamin/mineral/supplement intake and/or medication/natural therapy in response to their family history. The men expressed interest in genetic testing with 92% `definitely` or `probably` interested. Definite interest was associated with number of affected relatives and prostate cancer-related anxiety. A positive genetic test would motivate 93% of men to make at least one behavioral change. Conclusions: Participants commonly believed behavioral factors influenced prostate cancer risk and reported that they would alter their behavior to reduce risk after (hypothetical) genetic testing.
