Degrees of difficulty : an ecological account of learning in Australian higher education

In this article, the difficulties some Australian university students experience in academic learning environments are explored. Particular attention is given to the experiences of students whose difficulties are often portrayed as intrinsic to them, and who are diagnosed as having learning disabilities or 'disorders'. In so doing, dominant neuro-psychological perspectives on students' learning 'problems' are challenged, broadening the discussion to include sociocultural explanations of students' difficulties. Research that foregrounds these students' own accounts of their problems is reported, identifying a number of tests of time, association and dissimulation that they experience in coming to terms with the particular institutional requirements of university life. At the very least, these explanations draw attention to the need for university teaching scholars to also be learners, and to consider their own practices in the construction of learning difficulties for their students.

Prediction intervals to account for uncertainties in travel time prediction

The accurate prediction of travel times is desirable but frequently prone to error. This is mainly attributable to both the underlying traffic processes and the data that are used to infer travel time. A more meaningful and pragmatic approach is to view travel time prediction as a probabilistic inference and to construct prediction intervals (PIs), which cover the range of probable travel times travelers may encounter. This paper introduces the delta and Bayesian techniques for the construction of PIs. Quantitative measures are developed and applied for a comprehensive assessment of the constructed PIs. These measures simultaneously address two important aspects of PIs: 1) coverage probability and 2) length. The Bayesian and delta methods are used to construct PIs for the neural network (NN) point forecasts of bus and freeway travel time data sets. The obtained results indicate that the delta technique outperforms the Bayesian technique in terms of narrowness of PIs with satisfactory coverage probability. In contrast, PIs constructed using the Bayesian technique are more robust against the NN structure and exhibit excellent coverage probability.

Transition from clinical manager to university lecturer : a self-reflective case study

This paper is a case study exploring the author’s use of reflective practice to facilitate the transition in role from a clinical manager with teaching responsibilities in a critical care unit to university lecturer. The similarities and differences in the roles with respect to learner characteristics, teaching contexts and effective teaching strategies are discussed. Brookfield’s model provides the methodological framework for the process of critically reflective practice undertaken to support and inform the transition. This case study describes a novice academic’s reflection through the four lenses of autobiography, the theoretical literature, student feedback and the perspectives of colleagues as she seeks to optimise student engagement and learning using the large lecture as the teaching and learning activity. The author suggests that the use of a framework such as Brookfield’s model that supports critical reflection may be of significant benefit to accelerate the personal and professional growth of new academic staff in their teaching practice.

Psychosocial antecedents of communication, trust, and relationship effectiveness in new product development projects : a functional manager perspective

The basic differences between marketing managers and their technically trained counterpart managers [e.g., research and development (R&D), engineering, and manufacturing managers] in terms of work experience, training, and differing decision-making styles have often been suggested as a source of conflict, which acts as a barrier to effective working relationships and integration during new product development (NPD) work. In this paper, we empirically explore this issue by developing and testing a model of psychosocial differences (thought worlds and psychological distance) between the two groups of managers and their effect on communication, trust, and relationship effectiveness during NPD projects. We find that while thought world differences do still matter, it was from a marketing perspective that they had a stronger effect. These findings have implications for top management trying to manage the functional manager interface during NPD projects. We propose a semi-formalized approach to relationship building that may speed up the acquisition of social data that is often necessary to elevate working relationships to trusting ones and improve the efficiency of NPD work. Our model is tested using data from two samples, 184 technically trained managers and 145 marketing managers from Australian companies involved in NPD work.

Student perceptions of environmental management : profiling the future environmental manager

Large growth is expected in the environment industry in coming decades; especially in Australia where the government's new price on carbon began in July 2012. This growth inevitably raises the question of who will fill new environmental management roles. This article presents the perceptions and expectations of students who are beginning to think about a possible career in this sector; what influences their decision-making and how do they view a career as an environmental manager? Without this information the environment sector will be under prepared for the expectations of incoming recruits and may lose valued students, graduates and employees. We found that prospective environmental managers are passionate and committed individuals who express a desire to help create a better world. They fail, however, to adequately articulate what environmental management entails, and have a poor understanding of the industry. They appear to be worried about financial security in what they see as a growing, but not yet fully mature, industry. The environment sector must therefore take the opportunity to engage these future environmental managers, and to communicate where the field will lead and how it can help this next generation achieve their aspirations to ‘save the planet’.
