Implementation of risk management in the Australian public university sector: Insights from a collective action model of institutional innovation

Australian public universities are experiencing a change towards a corporate culture. This change process involves the adoption of a range of corporate control processes to facilitate effective governance. This study examines the extent to which one of these processes, risk management, is adopted under an environment of change management. The study draws on a collective action model of institutional innovation as the theoretical framework and utilizes a qualitative research methodology to analyse the extent of the adoption of this process. The findings confirm the theoretical propositions of the model and illustrates that specific actors in the sector frame issues, mobilize collective actions, and engage in contested processes in order to achieve different outcomes in the implementation of risk management. The study has provided insights into these different outcomes and suggests that an important causal factor is the different levels of impact of an organization’s wider influencing forces on the governance paradigm and consequently the various drivers and owners of the process. The study identified these different wider influencing forces and provides avenues for further research to test the theoretical proposition that universities need to recognize these wider influencing forces within their governance framework and address them to minimize tensions or conflicts in developing and implementing its governance processes

The Role of Chromatid Interference in Determining Meiotic Crossover Patterns

Plants, like all sexually reproducing organisms, create genetic variability by reshuffling parental alleles during meiosis. Patterns of genetic variation in the resulting gametes are determined by the independent assortment of chromosomes in meiosis I and by the number and positioning of crossover (CO) events during meiotic recombination. On the chromosome level, spatial distribution of CO events is biased by multiple regulatory mechanisms, such as CO assurance, interference and homeostasis. However, little is known about how multiple COs are distributed among the four chromatids of a bivalent. Chromatid interference (CI) has been proposed as a regulatory mechanism that biases distribution of multiple COs toward specific chromatid partners, however, its existence has not been well-studied and its putative mechanistic basis remains undescribed. Here, we introduce a novel method to quantitatively express CI, and take advantage of available tetrad-based genotyping data from Arabidopsis and maize male meiosis to quantify CI effects on a genome-wide and chromosomal scale. Overall, our analyses reveal random involvement of sister chromatids in double CO events across paired chromosomes, indicating an absence of CI. However, on a genome-wide level, CI was found to vary with physical distance between COs, albeit with different effects in Arabidopsis and maize. While effects of CI are minor in Arabidopsis and maize, the novel methodology introduced here enables quantitative interpretation of CI both on a local and genome-wide scale, and thus provides a key tool to study CI with relevance for both plant genetics and crop breeding

The interface between internal and external audit in the Australian public sector

This study seeks to answer the research question ‘using reliance as the pivotal consideration, what factors determine the efficient and effective interrelationship between internal and external audit?’, within the context of the Australian public sector. A qualitative approach, framed within agency theory, was adopted using a case study and structured interviews. Findings included factors supporting prior literature as well as some unique to the research described here. As a result, this article makes a contribution to the literature examining public sector internal and external audit interrelationships as well as the literature on police audit and performance. It also has practical implications for both the case study site and similar organisations throughout the world

Blau Syndrome-Associated Uveitis: Preliminary Results From an International Prospective Interventional Case Series

PURPOSE: Provide baseline and preliminary follow-up results in a 5-year longitudinal study of Blau syndrome. DESIGN: Multicenter, prospective interventional case series. METHODS: Baseline data from 50 patients from 25 centers worldwide, and follow-up data for patients followed 1, 2, or 3 years at the end of study enrollment. Ophthalmic data were collected at baseline and yearly visits by means of a standardized collection form. RESULTS: Median age at onset of eye disease was 60 months and duration of eye disease at baseline 145 months. At baseline 38 patients (78%) had uveitis, which was bilateral in 37 (97%). Eight patients (21%) had moderate to severe visual impairment. Panuveitis was found in 38 eyes (51%), with characteristic multifocal choroidal infiltrates in 29 eyes (39%). Optic disc pallor in 9 eyes (12%) and peripapillary nodules in 9 eyes (12%) were the commonest signs of optic nerve involvement. Active anterior chamber inflammation was noted in 30 eyes (40%) at baseline and in 16 (34%), 17 (57%), and 11 (61%) eyes at 1, 2, and 3 years, respectively. Panuveitis was associated with longer disease duration. At baseline, 56 eyes (75%) were on topical corticosteroids. Twenty-six patients (68%) received a combination of systemic corticosteroids and immunomodulatory therapy. CONCLUSIONS: Blau uveitis is characterized by progressive panuveitis with multifocal choroiditis, resulting in severe ocular morbidity despite continuous systemic and local immunomodulatory therapy. The frequency and severity of Blau uveitis highlight the need for close ophthalmologic surveillance as well as a search for more effective therapies
