Intuitive haptic control surface for mobile robot motion control

Haptic human-machine interfaces and similar techniques to enhancing human-robotic interaction offer significant potential over conventional approaches. This work considers achieving intuitive motion control of a tracked mobile robotic platform utilising a 3D virtual haptic cone. The 3D haptic cone extends upon existing approaches by introducing of a third dimension to the haptic control surface. It is suggested that this approach improves upon existing methods by providing the human operator with an intuitive method for issuing vehicle motion commands whilst still facilitating simultaneous real-time haptic augmentation regarding the task at hand. The presented approach is considered in the context of mobile robotic teleoperation however offers potential across many applications. Using the 2D haptic control surface as a benchmark, preliminary evaluation of the 3D haptic cone approach demonstrates a significant improvement in the ability to command the robot to cease motion.

Engagement and learning through social software in finance : the trading room experience

The introduction of a social software blog space called “The Trading Room” in an undergraduate Finance unit for an assessment task generated a great deal of activity to support student learning. A subsequent evaluation of this pilot demonstrated that students perceived high value in the opportunity it provided for them to reaffirm theories, obtain individualized feedback and benchmark their work against others. Whilst assessment is generally seen as both the carrot and the stick of learning, and certification; students in the study reported that they would still participate in reading and posting to the “Trading Room” blog even if there was no assessment requirement! Additionally they did not see any value in the environment as a purely social space, reporting that they saw it primarily as a professional educational community. It would appear that just as there are different communities in the real world social space, there are also different types of communities in the online space. Context, structure and activity design, perhaps are the most important facets of online interaction for learning.

Practical application of the Delphi technique in a bicultural mental health nursing study in New Zealand

Background. Numerous studies have employed the Delphi technique to seek expert opinion about aspects of clinical practice. When researching literature on the Delphi technique, however, we discovered discrepancies in its application, and a lack of detail when reporting design, administration, and analysis methods. Such lack of specificity hinders the replicability and assessment of the clinical and cultural validity and reliability of Delphi studies.

Aim. The aim of this paper is to detail the practical application of the Delphi technique as a culturally and clinically valid means of accessing expert opinion on the importance of clinical criteria.

Methods. Reference is made to a bicultural New Zealand mental health nursing clinical indicator study that employed a three-round reactive Delphi survey. Equal proportions of Maori and non-Maori nurses (n = 20) and consumers (n = 10) rated the importance of 91 clinical indicator statements for the achievement of professional practice standards. Additional statements (n = 21) suggested by Delphi participants in round 1 were included in subsequent rounds. In round 2, participants explained the rating they applied to statements that had not reached consensus in round 1, and summarized responses were provided to participants in round 3. Consensus was considered to have been achieved if 85% of round 3 ratings lay within a 2-point bracket on the 5-point Likert-scale overall, or in one of the Maori nurse, non-Maori nurse, or consumer groups. A mean rating of 4·5 after round 3 was set as the importance threshold.

Findings. Consensus occurred overall on 75 statements, and within groups on another 24. Most statements (n = 86) reached the importance benchmark.

Conclusions. When rigorous methods of participant selection, group composition, participant feedback, and determination of consensus and importance are employed, the Delphi technique is a reliable, cost-effective means of obtaining and prioritizing experts judgements.

Cooperative inquiry in a business school : scope, process and dimensions

The presentation will describe a cooperative inquiry project being undertaken within the School of Management and Marketing, Faculty of Business and Law. This project involves both HRM and Management academics and was commenced in February 2008 with the broad aim of developing an ongoing teaching and learning dialogue within these discipline areas to enhance teaching and learning.
The project is also aimed at enabling individuals and unit teams to develop and pursue their own priorities in teaching and learning and align these with the goals and objectives of the Faculty and University.
In the presentation we will describe the scope, nature and methods of the inquiry and the outcomes of the project to date. One major outcome to date has been a comprehensive review of all the units within the HRM and Management majors. This review has, in turn, lead to the initiation of four further projects.
These include an activity to benchmark the School’s HRM and Management units against universities in Australia and overseas; a literature review entitled ‘Linking practice, research and the scholarship of teaching’; a project that seeks to integrate individual and institutional needs; and an action research project to capture the process of change within the Management and HRM team. These four projects will be described briefly in the presentation.

What (a) difference a degree makes : the evaluation of the new social work degree in England

After many years of debate in the UK about the need for a degree-level qualification in social work, the arguments for a minimum degree-level qualification were accepted. The requirements for the degree in England were developed drawing on work from a number of sources, including a benchmark statement for undergraduate degrees in social work and focus groups with stakeholders. The new degree in England, launched in 2003, involves one extra year’s study; improvements in the qualifying standard for social work; and specific curriculum and entrance requirements. At the time of launching the degree, the government department responsible for funding (Department of Health) commissioned a three-year evaluation of the implementation of the new degree to establish whether the new qualifying level leads to improvements in the qualified workforce. The aim of the evaluation is to describe the experiences of those undertaking the degree, collect the views of the various stakeholders about the effectiveness of the degree and measure the impact of a degree-level qualification on those entering the workforce. This article, written by the team undertaking the evaluation of the England degree, explores the reasons for the methodological approach adopted and the issues that have arisen in setting up the research.

High prices for generics in Australia : more competition might help

It is commonly believed that dispensed prices of medicines in Australia are substantially lower than those in other developed countries, particularly the US. This article reports the results of an analysis comparing dispensed prices for the most commonly prescribed and the highest cost items in Australia with dispensed prices in the US. Although a large majority of items are less expensive in Australia than in the US, Australian prices are higher for a substantial number of products, particularly generic drugs. This article examines various policies affecting the pricing of generics in Australia. It is postulated that the main cause for higher prices for a substantial number of generic products is the lack of price competition. This results from government policy which ensures that a price reduction by one company is communicated immediately to all competitors in that market along with an invitation to match the reduced price. The dominant strategy for all suppliers is to only reduce their price in response to a reduction in price by a competitor. The result is a lack of differentiation in pricing across brands of a medicine on the Schedule of Pharmaceutical Benefits. The government could improve the structure of the generics market and encourage greater competition by ceasing to disclose competitor firms’ offers to other competitors. The government could conduct pricing reviews of each generic product relatively infrequently (eg, only once annually or every 18 months). At the time of the pricing review, the government would request confidential offers on price for a generic from all players in the market. Brands should then all be listed under the Pharmaceutical Benefits Scheme (PBS) at the offered price. Prices offered by the individual supplier would apply until the next pricing review. The PBS would continue to subsidise up to the price of the lowest priced brand, with brand premiums applying to all brands priced higher than the benchmark price. Such an approach would provide opportunity for players in the market to capture market share by being thelowest priced brand.

GEM New Zealand's different approach

At 13.9% of the adult population, New Zealand's ''Total Early-Stage Entrepreneurial Activity'' is highest amongst developed countries. This benchmark uses the Global Entrepreneurship Monitor (GEM) methodology. New Zealand has a high level of opportunity entrepreneurship and a moderate level of necessity entrepreneurship. New Zealand's entrepreneurial firms contribute about half of all new jobs created annually. Informal investment is a more important source of financing to entrepreneurs than venture capital. The proportion of female entrepreneurs has slipped over the past three years. Maori are more entrepreneurial than the rest of population. The study argues that New Zealand has an excellent innovation policy but no entrepreneurship policy.

Momentum profits in Australian listed property trusts

This paper examines the profitability of momentum trading strategies in Australian listed property trusts (LPTs). Monthly value-weighted momentum portfolios are formed using the monthly excess returns of LPTs for the period from 1990 to 2005. Overall the findings confirm that a momentum trading strategy in Australian LPTs is a profitable strategy. More specifically, momentum strategies are profitable after adjusting for variance and downside risk where the momentum returns substantially outperform the benchmark. An analysis using different study periods confirm the findings about momentum. The practical implication from this study is that investors can generate substantial abnormal returns by adopting a momentum trading strategy, particularly with a long strategy (i.e. winner portfolios).

The structural and behaviourial barriers to sustainable real estate development

Sustainable real estate development appears, on literal translation of both terms, to be an oxymoron - however it is a concept that the real estate profession needs to embrace knowledgably. On one hand it can be argued that real estate development is required for continued economic growth and the adoption of sustainability measures is required to mitigate climate change and global warming. Over the last few years there has been growth in the number of sustainability tools available to designers and operators of buildings. For example, in the US the LEED scheme enables designers to assess the environmental impact of their design and to benchmark the sustainability of the design against industry recognised criteria. LEED follows a similar format to the UK’s Building Research Establishment Environmental Assessment Method (BREEAM) introduced in 1990 and the Australian ‘GreenStar’ introduced in 2004. Even though there are an increasing number of sustainability tools available to designers, it still remains that the degree of uptake of the tools has been sporadic. This paper discusses the barriers to sustainable real estate development. Firstly it identifies the barriers to uptake and secondly it establishes the structural barriers in the market which prevent the wider uptake of tools.
