Professional identity and the contemporary university: a culture of control, accountability and virtuality?

In recent years many changes to the funding and management of universities have taken place. In the current climate of academia in Australia professional academics find themselves immersed in the culture of the managed university that uses the rhetoric of commitment to flexible delivery to put in place systems designed to increase accountability, surveillance and control. At the same time some argue that the focus on research, quality teaching and effective pedagogy has lessened. The empirical research base for this paper has enabled me to better understand some of the emerging trends my university. It looks at how changes to the experience of being academic impact on the work of academics as the power relations of the university continuously reposition them, and how academics in turn display resistance technologies. Changes to the technologies of management/administration of the university have resulted in what some academics have described as a loss of valuing of their knowledge and expertise and which may be seen by some as a threat to their opportunities to conduct productive educational inquiry.

The use of control systems in new product development innovation : advancing the 'help or hinder' debate

New Product Development (NPD) innovation is a critical activity in the current economic environment. In order to manage their NPD innovation projects, firms use Management Controls Systems (MCS). However, the effect that these systems have on NPD innovation is not clear. One stream of research suggests that MCS help NPD innovation while another stream suggests MCS hinder NPD innovation. Past research has shown that the role and style of MCS used may offer explanations on why MCS can both help and hinder NPD innovation. This paper adds another explanation by examining the relationship between three models (divisional, activity/decision and conversion/response) of a commonly used MCS, known as the Stage-Gate Process1 in the NPD innovation literature, and three types of NPD innovation projects (incremental, semi-radical and radical). The insights from an ethnomethodology informed field study are used to understand how and why the firms may use a different MCS (Stage-Gate Process models) for different NPD innovation project types.

A prospective study on building quality : enforcement of control in the Australian housing industry

The Australian housing industry is beset with quality issues with repeated building defects causing problems with customer satisfaction and housing performance. These defects are caused by a combination of initial poor workmanship and poor quality materials and subsequently by poorly executed or inadequate maintenance. These poor work practices increase the cost and maintenance of housing. The waste and rectification work generated by such practices means that the housing industry generally is not engaged with sustainability. Building Control is part of achieving quality of building output. Whilst the Australian Building Code has regulations for initial-build material quality and workmanship, there is no continuing control and effective enforcement over a house over its life span. Sustainability is not dealt with as a topic at all in the Building Code with only energy efficiency concerns regulated. Inadequate knowledge transfer, to the mainly small builders who produce the majority of Australia’s housing, is seen to be a key issue. Mechanisms to make the transfer of knowledge to those who need to use it need to be improved. Building regulations, for example, could be more visual and accessible in their content and small builders should be encouraged to update their knowledge and skills. This comparative research will guide industry service providers in improving their performance and suggest how overall housing quality can be improved (thereby reducing wasteful practices), by considering more appropriate mechanisms for knowledge transfer among industry service providers in the Australian housing industry.

Malware variant detection using similarity search over sets of control flow graphs

Static detection of polymorphic malware variants plays an important role to improve system security. Control flow has shown to be an effective characteristic that represents polymorphic malware instances. In our research, we propose a similarity search of malware using novel distance metrics of malware signatures. We describe a malware signature by the set of control flow graphs the malware contains. We propose two approaches and use the first to perform pre-filtering. Firstly, we use a distance metric based on the distance between feature vectors. The feature vector is a decomposition of the set of graphs into either fixed size k-sub graphs, or q-gram strings of the high-level source after decompilation. We also propose a more effective but less computationally efficient distance metric based on the minimum matching distance. The minimum matching distance uses the string edit distances between programs' decompiled flow graphs, and the linear sum assignment problem to construct a minimum sum weight matching between two sets of graphs. We implement the distance metrics in a complete malware variant detection system. The evaluation shows that our approach is highly effective in terms of a limited false positive rate and our system detects more malware variants when compared to the detection rates of other algorithms.

Desire for control, sense of control and obsessive-compulsive symptoms

While control-related cognitions have often been implicated in discussions of Obsessive Compulsive Disorder (OCD), empirical investigations of the relationship between control-constructs and OCD symptoms have been relatively limited. In this article it was hypothesized that OCD symptoms may be linked with a higher desire to control (DC), but a lower sense of control (SC) over the self and environment, leading to motivation for compulsive symptoms. This hypothesis was investigated in an analogue population, using regression analyses controlling for depression and anxiety. Consistent with predictions, it was found that higher levels of DC and lower levels of SC were associated with higher levels of OCD-related beliefs and symptoms. While control cognitions were linked with the OCD-related beliefs of perfectionism and the over-estimation of threat, they did not relate to cognitions concerning the importance of/need to control thoughts. With respect to specific OCD-symptoms, control cognitions were most strongly related to contamination obsessions/washing compulsions. Implications for theory and treatment are discussed.

Provision of control measures for exposure of the hands to wet-working conditions in Australian workplaces

Objective: To analyze the occupational and demographic characteristics for workers participating in the Australian National Hazard Exposure Worker Surveillance (NHEWS) Survey, who reported the provision of various types of workplace control measures for exposure of the hands to wet-working conditions, and to identify the barriers for the provision of controls. Methods: Computer-assisted telephone interviews were conducted with 4500 workers in 2008. Workers were asked about the types of control measures provided to them in the workplace for exposure of the hands to liquids. Results: Workplace size was the strongest predictor for the provision of control measures. Compared to workplaces with fewer than five employees, workers in workplaces with 200 or more employees were more likely to report provision of gloves, barrier creams and moisturizers, labeling and warning, and ongoing training and education about skin care. Conclusion: Smaller workplaces have poorer access to control measures to mitigate exposure to wet work.

Self-reported racism and experience of toothache among pregnant Aboriginal Australians: the role of perceived stress, sense of control, and social support

Objectives We hypothesized that the psychosocial factors perceived stress and sense of personal control mediated the relationship between self-reported racism and experience of toothache. We hypothesized that social support moderated this relationship. Methods Data from 365 pregnant Aboriginal Australian women were used to evaluate experience of toothache, socio-demographic factors, psychosocial factors, general health, risk behaviors, and self-reported racism exposure. Hierarchical logistic regression models estimated odds ratios (ORs) and 95 percent confidence intervals (CIs) for experience of toothache. Perceived stress and sense of personal control were examined as mediators of the association between self-reported racism and experience of toothache. Social support was examined as a moderator. Results Self-reported racism persisted as a risk indicator for experience of toothache (OR 1.99, 95 percent CI 1.07-3.72) after controlling for age, level of education, and difficulty paying a $100 dental bill. The relationship between self-reported racism and experience of toothache was mediated by sense of control. The direct effect of self-reported racism on experience of toothache became only marginally significant, and the indirect effect was significant (β coefficient-=-0.04, bias-corrected 95 percent CI 0.004-0.105, 21.2 percent of effect mediated). Stress was insignificant as a mediator. Social support was insignificant as a moderator. Conclusions The findings indicate that high levels of self-reported racism were associated with experience of toothache and that sense of control, but not perceived stress, mediated the association between self-reported racism and experience of toothache among this sample of pregnant Aboriginal Australian women. Social support did not moderate the association between self-reported racism and experience of toothache.
