The educative value of values

There appears to be increasing interest among certain educational institutions to include values as a prominent feature of their practice (Buckley & Erricker, 2004). One recent example is the Victorian Curriculum Assessment Authority (VCAA) who released a discussion paper earlier this year, which indicates that values are to play a much greater role in government schools. However, endeavouring to promote values as common standards can be criticised to be problematic in our pluralist society, because not all values are necessarily valuable.

This paper reviews the VCAA paper and attempts to respond to Nietzsche’s (1998) challenge to question the value of our values, by offering guidance as to how the educative value of values might be determined. Such an examination is expected to identify a potential tension between a particular civic education and that of a more philosophic and universally educative perspective. In order to do this, a differentiation between a value (noun) as ‘objective fact’ and value (verb) as a ‘subjective relation’ is made. This paper will adopt an existential perspective by drawing upon consequentialism, intentionality and the works of Kierkegaard and Dewey, to argue that emphasis should be placed on the subjective aspects of educative valuing without fostering an objective/subjective divide.

The habitat value of Gorse Ulex europaeus L. and Hawthorn Crataegus monogyna Jacq. for birds in Quarry Hills Bushland Park, Victoria

Weeds are one of the primary threats to biodiversity; however, their impacts on wildlife can vary. This research investigated the habitat value of Gorse Ulex europaeus L. and Hawthorn Crataegus monogyna Jacq. and the impacts of its removal on birds in a bushland park in Victoria. The area search method was used to survey birds in vegetation dominated by these two weeds, in native vegetation and in areas where a weed removal program was undertaken; this included revegetated areas. The highest bird species richness and abundance was found in sites dominated by the weeds. At sites where the weed removal program was in the early stages, a much lower species richness and abundance occurred. The final stage of the weed removal program, where revegetated areas were older than five years, supported high richness and abundance of birds, but not as high as that of sites dominated by the weeds; nor was the composition the same. Thus, even after five years, revegetation may not provide for the bird community that was originally supported by weeds. This is an important weed management consideration in this park, and should be for weed removal projects elsewhere

Enabling strategic transformations with enterprise systems : beyond operational efficiency

The last few decades have seen the widespread adoption of large-scale, integrated, packaged software suites collectively called Enterprise Systems. However, most studies done so far have largely focused on the operational efficiency achieved by using these systems. This paper reports on research-in-progress that seeks to explore the strategic potential of Enterprise Systems to enable business transformations. In doing so, a new model is proposed that places the emphasis on the potential of Enterprise Systems to achieve innovation and reshape business strategy, rather than merely focusing on operational benefits. This model proposes that Enterprise Systems, when used to integrate, optimise and informate, can help firms achieve alliance innovation, process innovation and reshaped business strategy. The paper also provides preliminary empirical evidence that supports the propositions. This model will be tested further through primary case studies and a survey. This research, once completed, will assess the strategic role of Enterprise Systems in enabling business transformations beyond operational benefits.

A preliminary analysis of the cost-effectiveness of the National Bowel Cancer Screening Program – demonstrating the potential value of comprehensive real world data

Background The complexity and cost of treating cancer patients is escalating rapidly and increasingly difficult decisions are being made regarding which interventions provide value for money. BioGrid Australia supports collection and analysis of comprehensive treatment and outcome data across multiple sites. Here we use preliminary data regarding the National Bowel Cancer Screening Program (NBCSP) and stage-specific treatment costs for colorectal cancer (CRC) to demonstrate the potential value of real world data for cost-effectiveness analyses (CEA).

Methods Data regarding the impact of NBCSP on stage at diagnosis was combined with stage-specific CRC treatment costs and existing literature. An incremental CEA was undertaken from a government healthcare perspective, comparing NBCSP to no-screening. The 2008 invited population (n=681,915) was modelled in both scenarios. Effectiveness was expressed as CRC-related life years saved (LYS). Costs and benefits were discounted at 3% per annum.

Results Over the lifetime and relative to no-screening, NBCSP was predicted to save 1,265 life-years, prevent 225 CRC cases and cost an additional $48.3 million, equivalent to a cost-effectiveness ratio of $38,217 per LYS. A scenario analysis assuming full participation improved this to $23,395.

Conclusions This preliminary CEA based largely on contemporary real world data suggests population-based FOBT screening for CRC is attractive. Planned ongoing data collection will enable repeated analyses over time, using the same methodology in the same patient populations, permitting an accurate analysis of the impact of new therapies and changing practice. Similar CEA using real world data related to other disease types and interventions appears desirable.

The value of experiential learning for providing a contextual understanding of the construction process

This research investigates effectiveness of real site visits within an undergraduate course. Experiential learning is a process of providing education, based on the experiences and observations of real-world examples. Some of the theory of experiential learning has been used to examine whether site visits assist the students learning experience.

The results of the research show that students generally have a positive attitude towards site visits and see them as beneficial. Although the study identified that some aspects of construction technology could be easily replaced by computer simulations and the like, other aspects of the curriculum are more effectively taught by retaining real site visits. The research was intended to provide a more structured approach to determining the value of site-based learning in construction-related courses.

The value of oral history in natural resource management : the Balcombe Estuary Reserve, Mount Martha, Victoria

This study investigates the benefits of using oral history as a tool for the sustainable management of estuaries. Twenty-two semi-structured interviews were conducted to generate oral history records for the Balcombe Estuary Reserve, a small estuary in a periurban zone on the Mornington Peninsula, Victoria. These interviews establish a more complete picture of changes in land use and ecological change to the estuary since European settlement of the area, and document community values. The interviews were followed with a survey to further explore management issues in the area. Use of oral history was found to be an effective approach to assist holistic estuarine management, especially when complemented by other sources of information.

A note on the property rights theory and the ex ante value of information

This paper examines the ex ante value of information in the property rights model where the possibility exists that an investing agent can be provided with relevant information before investments are undertaken. When contracts are incomplete, from an ex ante perspective, informing the investing agent does not necessarily increase the expected surplus resulting from a relationship between two economic agents. The paper highlights the fact that the second-best nature of the problem that arises from contractual incompleteness can ensure this.

Assessment of fracture risk : value of random population-based samples - the Geelong Osteoporosis Study

Fracture risk is determined by bone mineral density (BMD). The T-score, a measure of fracture risk, is the position of an individual's BMD in relation to a reference range. The aim of this study was to determine the magnitude of change in the T-score when different sampling techniques were used to produce the reference range. Reference ranges were derived from three samples, drawn from the same region: (1) an age-stratified population-based random sample, (2) unselected volunteers, and (3) a selected healthy subset of the population-based sample with no diseases or drugs known to affect bone. T-scores were calculated using the three reference ranges for a cohort of women who had sustained a fracture and as a group had a low mean BMD (ages 35-72 yr; n = 484). For most comparisons, the T-scores for the fracture cohort were more negative using the population reference range. The difference in T-scores reached 1.0 SD. The proportion of the fracture cohort classified as having osteoporosis at the spine was 26, 14, and 23% when the population, volunteer, and healthy reference ranges were applied, respectively. The use of inappropriate reference ranges results in substantial changes to T-scores and may lead to inappropriate management.
