Overcoming data constraints to create meaningful ecological models

Many techniques used to model ecosystems cannot be meaningfully applied to large-scale ecological problems due to data constraints. Disparate collection methods, data types and incomplete data sets, or limited theoretical understanding mean that a wide range of modelling techniques used to model physical processes or for problems specific to species or populations cannot be used at an ecosystem scale. In developing an ecological response model for the Coorong, a South Australian hypersaline estuary, we combined several flexible modelling approaches in a statistical framework to develop an approach we call ‘ecosystem states’. This model uses simulated hydrodynamic conditions as input to predict one of a suite of states per space and time, allowing prediction of likely ecological conditions under a variety of scenarios. Each ecosystem state has defined sets of biota and physico-chemical parameters. The existing model is limited in that its predictions have yet to be tested and, as yet, no spatial or temporal connectivity has been incorporated into simulated time series of ecosystem states. This approach can be used in a wide range of ecosystems, where enough data are available to model ecosystem states. We are in the process of applying the technique to a nearby lake system. This has been more difficult than for the Coorong as there is little overlap in the spatial and temporal coverage of biological data sets for that region. The approach is robust to low-quality biological data and missing environmental data, so should suit situations where community or management monitoring programs have occurred through time.

Ethics education in the Australian accounting curriculum: a longitudinal study examining barriers and enablers

Abstract: The increasing significance of ethics in the accounting profession is evidenced by the seminal events that witnessed the collapse of major corporations (eg. Enron and WorldCom); regulatory interventions (eg. Sarbanes-Oxley Act in the USA and the CLERP 9 Act in Australia); and calls for increased ethics interventions in the accounting curriculum. This project has two objectives: to investigate the nature of ethics education in the Australian accounting curriculum and how it has changed from 2000 to 2012; and to analyse the barriers to enhancing ethics education by soliciting the opinions of Heads of Department/Schools of Australian universities. Compared with early empirical evidence, universities responded to the call for ethics education with increased levels of ethics intervention, but had failed to enhance the extent of ethics education coverage in the intervening period in which the data were collected. He lack of qualified staff and research opportunities represent major obstacles to the enhancement of ethics education.

Professional development and accountability: working with newly appointed staff to foster quality

The aim of this paper is to examine some issues in professional development and the accountability of academic staff particularly in regard to newly appointed staff. It examines ways in which universities can assist new staff develop their skills in the various aspects of their academic role and identifies the responsibilities of the university and heads of departments in this task. It illustrates these issues by reference to a case study of a major Australian university which has recently adopted a department-based scheme for the professional development of academic staff. This scheme, amongst other things, involves new staff in planning sessions with the head of their department and the keeping of records of responsibilities, achievements, needs for professional development and the resources which will be provided to assist staff. The introduction of any scheme for accountability of staff or of professional development is likely to encounter some resistance in the prevailing academic ethos. The paper will examine ways in which the genuine fears of some groups can be addressed and how such schemes may be developed and introduced in a sensitive fashion.

Measuring organisational capabilities in the higher education sector

Purpose – Drawing on the resource-based view (RBV), the purpose of this paper is to develop a framework and instrument to measure the organisational capabilities of university schools/ departments. In doing so, this study provides evidence of the way competitive resources are bundled to generate organisational capabilities that give university schools/departments a sustainable competitive advantage. Design/methodology/approach – A questionnaire to measure the resources that contribute to the capabilities of university schools/departments was developed. Constructs were determined, and the questionnaire was refined based on an analysis of responses from 166 Heads of schools/departments across all 39 Australian public universities. Findings – Heads conceive of the development of capabilities within their schools/departments along the core operating functions of research, teaching, and networking. Reliability and supplementary analysis confirm these constructs have strong convergent and discriminant validity as well as internal consistency. Research limitations/implications – The findings confirm that effective management and coordination of research, teaching, and networking with important stakeholders are keys to success. The framework and instrument developed in this paper also provides the opportunity to investigate university performance through the perspective of the RBV, which will enhance the understanding of the determinants of universities’ performance. Practical implications – The framework and questionnaire developed in this study can be utilised by Heads as a diagnostic tool to gain an understanding of their department’s/school’s organisational capabilities in the areas of research, teaching, and networking. Originality/value – This paper is the first study to develop a framework and questionnaire to measure organisational capabilities for university academic schools/departments.
