Story as a vehicle for learning in online role play : a case study

In online role plays, students are asked to engage with a story that serves as a metaphor for real-life experience as they learn and develop skills. However, practitioners rarely examine the characteristics and management of this story as factors in the students' engagement in and learning from the activity. In this paper I present findings from a recent case study which examines these factors in an online role play that has been named as an exemplar and has been run for 19 years in Australian and international universities to teach Middle East politics and journalism. Online role plays are increasingly popular in tertiary education, in forms ranging from simple text-based role plays to virtual learning environment activities and e-simulations. The role play I studied required students to communicate in role via simulated email messages and draw on real-life resources and daily simulated online newspaper publications produced by the journalism students rather than rely on information or automated interactions built into an interface. This relatively simple format enabled me to observe clearly the impact of the technique's basic design elements. I studied both the story elements of plot, character and setting and the non-story elements of assessment, group work and online format. The data collection methods include analysis of student emails in the role play, a questionnaire, a focus group, interviews and the journal I kept as a participant-observer in the role play. In evaluating the qualities and impact of story elements I drew upon established aesthetic principles for drama and poststructuralist drama education.

How precarious employment affects health and safety at work : the case of temporary agency workers

International studies indicate temporary agency workers are more likely to be injured at work than other types of employees. However explanations for this have been less forthcoming. This paper seeks to begin filling this gap. A study was undertaken in Victoria, Australia, of occupational health and safety (OHS) amongst temporary agency workers drawing upon workers' compensation claim files for injured agency and directly hired workers from 1995-2001, and focus groups of temporary agency workers conducted in 2003. In analyzing the results, use was made of risk factors identified in a model that has been developed to explain how precarious employment affects OHS--the pressure, disorganization and regulatory failure (PDR) model (Quinlan and Bohle, 2004, 2009). Drawing principally on qualitative data, the paper finds that whilst agency workers share common risk factors with other forms of precarious workers, unique characteristics associated with the triangular nature of agency employment heighten their vulnerability further.

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.

Multilocus phylogeography of Australian teals (Anas spp.) : a case study of the relationship between vagility and genetic structure

Biogeographic barriers potentially restrict gene flow but variation in dispersal or vagility can influence the effectiveness of these barriers among different species and produce characteristic patterns of population genetic structure. The objective of this study was to investigate interspecific and intraspecific genetic structure in two closely related species that differ in several life-history characteristics. The grey teal Anas gracilis is geographically widespread throughout Australia with a distribution that crosses several recognized biogeographic barriers. This species has high vagility as its extensive movements track broad-scale patterns in rainfall. In contrast, the closely related chestnut teal A. castanea is endemic to the mesic southeastern and southwestern regions of Australia and is more sedentary. We hypothesized that these differences in life-history characteristics would result in more pronounced population structuring in the chestnut teal. We sequenced five nuclear loci (nuDNA) for 49 grey teal and 23 chestnut teal and compared results to published mitochondrial DNA (mtDNA) sequences. We used analysis of molecular variance to examine population structure, and applied coalescent based approaches to estimate demographic parameters. As predicted, chestnut teal were more strongly structured at both mtDNA and nuDNA (ΦST= 0.163 and 0.054, respectively) than were grey teal (ΦST < 0.0001 for both sets of loci). Surprisingly, a greater proportion of the total genetic variation was partitioned among populations within species (ΦSC= 0.014 and 0.047 for nuDNA and mtDNA, respectively) than between the two species (ΦCT < 0.0001 for both loci). The ‘Isolation with Migration’ coalescent model suggested a late Pleistocene divergence between the taxa, but remarkably, a deeper divergence between the southeastern and southwestern populations of chestnut teal. We conclude that dispersal potential played a prominent role in the structuring of populations within these species and that divergent selection associated with ecology and life history traits likely contributed to rapid and recent speciation in this pair.

Exploring the moderating role of growth options on the relation between board characteristics and management earnings forecasts

Manuscript Type
Empirical
Research Question/Issue
This study examines whether director independence, reputation, and financial expertise are related to management earnings forecast (MEF) activity. In particular, we examine whether such a relationship is moderated by firms’ growth options.
Research Findings/Insights
Using Australian archival data for 1,928 firm-years between 1999 and 2006, we find several board characteristics have a significant positive relationship with: (1) the likelihood of firms issuing MEFs; (2) their specificity; (3) their accuracy; and (4) a negative relationship with their bias. For (1), (2), and (3) we show that these relationships are accentuated for firms with high growth options.
Theoretical/Academic Implications
While the theory of voluntary disclosure suggests firms will disclose information that is favorable to them or their managers, well-governed firms issue informative MEFs that potentially reduce information asymmetries in capital markets. We extend the prior literature by showing that such a relation is enhanced in the presence of information asymmetry and moral hazard associated with growth options.
Practitioner/Policy Implications
Our results have strategic implications for nomination committees by showing that independent directors and those with strong reputations and financial expertise enhance the governance of high growth firms. We also inform the regulatory debate by showing that good corporate governance enhancing disclosure quality is context-specific – it is not a case of “one size fits all”.

Kinematics analysis of 6-DOF parallel micro-manipulators with offset U-Joints : a case study

This paper analyses the kinematics of a special 6-DOF parallel micro-manipulator with offset RR-joint configuration. Kinematics equations are derived and numerical methodologies to solve the inverse and forward kinematics are presented. The inverse and forward kinematics of such robots compared with those of 6-UCU parallel robots are more complicated due to the existence of offsets between joints of RR-pairs. The characteristics of RR-pairs used in this manipulator are investigated and kinematics constraints of these offset U-joints are mathematically explained in order to find the best initial guesses for the numerical solution. Both inverse and forward kinematics of the case study 6-DOF parallel micro-manipulator are modelled and computational analyses are performed to numerically verify accuracy and effectiveness of the proposed methodologies.

The contribution of creativity to human development in a new nation: a case study of Afalyca community art centre, Timor-Leste

This article describes the contribution of creativity to human development in the new nation of Timor-Leste, exemplified in a case study of community art centre Afalyca. By taking a creative approach to the challenges of life in his developing country, the young leader of this enterprise, Marqy da Costa, is realising his own potential more fully and offering enriching experiences to others. The impact of his centre on a range of stakeholders, including staff, participants and the wider community is discussed. For participants, the outcomes of their involvement include enjoyable opportunities for creative expression; valued recognition from national and international audiences; the broadening of life experience to encompass new possibilities for self-actualisation; skill development and income from employment and sales.

The factors that have contributed to Afalcya's creative achievements are examined. These include inspiration and assistance received from organisations and individuals in and outside of Timor, family support, and the age and gender of leaders. Also significant are founder Marqy's personal characteristics of artistic talent, social and language skills, love of learning, persistence and conciliatory approach to conflict. Barriers to the realisation of Afalcya's potential include lack of systemic recognition of the value of creativity for sustainable development, unsupportive bureaucracy and gender related restrictions of participation for women. The potential for similar initiatives to contribute to a positive future for Timorese people is explored.

A case study on effect of feed rate on machinability of austempered ductile iron

Austempered Ductile Iron (ADI) is a type of nodular, ductile cast iron subjected to heat treatments - austenitising and austempering. Whilst machining is conducted prior to heat treatment and offers no significant difficulty, machining post heat treatment is demanding and often avoided. Phase transformation of retained austenite to martensite leading to poor machinability characteristics is a common problem experienced during machining. This case study explains the effect of feed rate on machinability of ADI using cutting force analysis and tool failure analysis. The experimental design consists of conducting drilling trials on grade 1200 and 1400 at constant depth of cut, 25mm; constant speed, 45m/min; no coolant and variable feed rates from 0.2 to 0.35 mm/rev (increment of 0.025mm/rev). Metallography and X-ray diffraction technique was carried out in order to identify and quantify the microstructural phases before and after drilling. The results from the trial infer that the best way to machine ADI efficiently without tool failure is using low feeds and high speeds and without coolant.

Contributions of school design to adolescent identity formation : case studies of four Australian secondary schools

The paper presents a summary of the study that examined the relationship between school design and adolescent identity formation. Reviewing theories and empirical studies of identity development, three major processes involved in adolescent identity formation were identified: (1) separation or individuation process, (2) social integration or relational connectedness, and (3) developmental exploration. Two key characteristics of schools that support these identity formation processes were proposed: (1) having a supportive environment addressing needs for individuation and social integration, and (2) providing opportunities for developmental exploration. Implications of these characteristics for school design were studied through a review of research and practices of learning space design. Four secondary schools in Australia which represented an innovative approach to learning space design were then examined to provide insights into these design-related implications and better understand issues and challenges associated with them. The paper concludes with proposing five design principles which supports adolescent identity development through contributing to processes involved in identity formation.

Characteristics and applications of energy storage system to power network - A review

Maintaining reliability and stability of a power systems in transmission and distribution level becomes a big challenge in present scenario. Grid operators are always responsible to maintain equilibrium between available power generation and demand of end users. Maintaining grid balance is a bigger issue, in case of any unexpected generation shortage or grid disturbance or integration of any renewable energy sources like wind and solar power in the energy mix. In order to compensate such imbalance and to facilitate more renewable energy sources with the grid, energy storage system (ESS) started to be playing an important role with the advancement of the state of the art technology. ESS can also help to get reduction in greenhouse gas (GHG) emission by means of integrating more renewable energy sources to the grid. There are various types of Energy Storage (ES) technologies which are being used in power systems network from large scale (above 50MW) to small scale (up to 100KW). Based on the characteristics, each storage technology has their own merits and demerits. This paper carried out extensive review study and verifies merits and demerits of each storage technology and identifies the suitable technology for the future. This paper also has conducted feasibility study with the aid of E-SelectTM tool for various ES technologies in applications point of view at different grid locations. This review study helps to evaluate feasible ES technology for a particular electrical application and also helps to develop smart hybrid storage system for grid applications in efficient way.

Energy performance of medium-sized healthcare buildings in Victoria, Australia- a case study

This paper investigates the energy performance of three medium-sized healthcare buildings in Victoria, Australia, that operate only during the daytime. The aim is to provide preliminary understanding of energy consumption in this particular typology in Australia in relation to the available benchmarks. This paper also identifies the differences of energy consumption between different functional areas within medium health facilities. Building features and operational characteristics contributing to the variations in healthcare energy performance are discussed. The total annual energy consumption data ranging from 167-306 kWh/m(2) or 42-72 kWh/m(3) were compared against international data from various climatic zones. Some of the drivers of energy consumption were determined and potentials for energy and water conservation were identified. Comparison with international standards shows a possibility to achieve lower energy consumption in Victorian healthcare buildings.

Evaluation of University of Queensland Library Spaces: three case studies at St Lucia Campus

Introduction: The paper reports on an evaluation study of spaces in the Social Sciences and Humanities (SSHL), Biological Sciences (BSL) and Walter Harrison Law (WHLL) Libraries of the University of Queensland (UQ). The study was part of an evaluation of the quality and patterns of use of spaces in UQ libraries, which aimed to propose recommendations for future improvements and decision-making. This paper presents a study of areas of weakness in existing SSHL spaces, and impacts of the refurbishment of spaces at BSL and WHLL on students’ experiences. The findings evidence a link between students’ learning experiences and the quality of library spaces.Methods: An online survey, “Students’ Experiences and Perceptions of Library Physical Spaces”, was designed to collect data from students. The survey questions addressed seven topics: (1) overall satisfaction with spaces in the UQ Libraries; (2) welcoming nature of the library entry; (3) lighting; (4) acoustics; (5) furniture; (6) wayfinding; and (7) preferences for different space types in the library.Results: 1505 students completed the surveys, with 1098 responses recorded to open-ended questions on why students visited the libraries and the physical characteristics of the spaces that influenced their experiences. Quantitative and qualitative analysis of the data elucidated key design challenges and considerations. In particular, the data suggested that the provision of individual quiet study spaces remains an important role of academic libraries, with Studying Alone identified as the most important reason for student visits.Conclusions: The findings highlight the importance of individual study spaces and propose a number of recommendations in relation to physical space design and management.Relevance: Academic libraries face the challenge to keep pace with change in relation to students’ demographics, pedagogy and technology. In doing so, it is important to have an understanding of the evolving patterns of students’ learning behaviours, space uses and preferences through ongoing evaluation of library spaces.

Drying and denaturation characteristics of α-lactalbumin, β-lactoglobulin, and bovine serum albumin in a convective drying process

Drying and denaturation kinetics of aqueous droplets of α-lactalbumin (α-lac), β-lactoglobulin (β-lg), and bovine serum albumin (BSA) were measured in a convective drying environment. Single droplets having an initial droplet diameter of 2 ± 0.1 mm and containing 10% (w/v) protein concentration were dried using conditioned air (65 and 80 °C, 2-3% RH, 0.5 m/s velocity) for 600 s. The denaturation of these proteins was measured by using reversed-phase HPLC. At the end of 600 s of drying 13.3 and 19.4% α-lac was found to be lost due to denaturation at 65 and 80 °C, respectively. Up to 31.0% of β-lg was found to be denatured, whereas BSA was not found to be significantly (p > 0.05) denatured in these drying conditions. The formation and strength of skin and the associated morphological features were found to be linked with the degree of denaturation of these proteins. The secondary structure of these proteins was significantly (p < 0.05) affected and altered by the drying stresses. The β-sheet and random coil contents were increased in α-lac by 6.5 and 4.0%, respectively, whereas the α-helix and β-turn contents decreased by 5.5 and 5.0%, respectively. The β-sheet and random coil contents in β-lg were increased by 7.5 and 2.0%, respectively, whereas the α-helix and β-turn contents decreased by 3.5 and 6.0%, respectively. In the case of BSA the β-sheet, α-helix, and random coil contents were found to increase, whereas the β-turn content decreased.
