University marketing and the law: applying the trade practices Act to universities` marketing and promotional activities

Application of the Trade Practices Act and its State equivalents to the  marketing by universities of the courses they teach - ramifications of the Act  are not understood within the wider university community, importantly by   those responsible for marketing courses - the Act prescribes many forms of  conduct not instantly recognised as morally reprehensible and are not  automatically avoided on the ground that they are inconsistent with  acceptable behaviour - the Act creates significant proscriptions, applicable to universities and their staff, which can have serious consequences.

An exploration of the relationships between food lifestyle and vegetable consumption

A short questionnaire was completed by 276 South Australian consumers, which examined postulated relationships between personal values, food lifestyle, demographics and their usual consumption of 24 vegetables. Principal components analyses showed that consumers' vegetable consumption could be divided into several categories, most notably salad and boiled vegetables. In multiple regression analyses different sets of values and lifestyle factors predicted intakes of overall vegetable (Rsq=27 per cent), salad (16 per cent) and boiled (27 per cent) vegetables. Path analysis revealed a complex set of pathways leading from values and personal demographics through motives, perceived food attributes and cooking skills to consumption. These partly confirmed the food lifestyle model proposed by Grunert et al. The findings show that vegetable consumption has a number of contextual and cognitive antecedents but strongly suggest that other likely predictive variables require investigation.

Two important exceptions to the relationship between energy density and fat content: food with reduced-fat claims and high-fat vegetable-based dishes

Objective: To test the hypothesis that many foods with reduced-fat (RF) claims are relatively energy-dense and that high-fat (HF) vegetable-based dishes are relatively energy-dilute.

Design: Nutrient data were collected from available foods in Melbourne supermarkets that had an RF claim and a full-fat (FF) equivalent. Nutrient analyses were also conducted on recipes for HF vegetable-based dishes that had more than 30% energy from fat but less than 10% from saturated fat. The dietary intake data (beverages removed) from the 1995 National Nutrition Survey were used for the reference relationships between energy density (ED) and percentage energy as fat and carbohydrate and percentage of water by weight.

Statistics: Linear regression modelled relationships of macronutrients and ED. Paired t-tests compared observed and predicted reductions in the ED of RF foods compared with FF equivalents.

Results: Both FF and RF foods were more energy-dense than the Australian diet and the HF vegetable-based dishes were less energy-dense. The Australian diet showed significant relationships with ED, which were positive for percentage energy as fat and negative for percentage energy as carbohydrate. There were no such relationships for the products with RF claims or for the HF vegetable-based dishes.

Conclusion: While, overall, a reduced-fat diet is relatively energy-dilute and is likely to protect against weight gain, there appear to be two important exceptions. A high intake of products with RF claims could lead to a relatively energy-dense diet and thus promote weight gain. Alternatively, a high intake of vegetable-based foods, even with substantial added fat, could reduce ED and protect against weight gain.

Section 46 of the Trade Practices Act-has the High Court made a "u-turn" on "taking advantage"?

Examination of High Court decisions on misuse of market power in regard to the element of "taking advantage" reveals inconsistency of application. Whilst being consistent regarding the need for a connection between the market power and the impugned conduct, the High Court has not been consistent regarding the degree of connection required. Two streams have developed, one supporting a high degree of connection, the other a lower degree before a firm is found to have "taken advantage" of its market power. Added to this has been the development of the "rational business explanation" which, it is argued, is either used as a defence to a s 46 action or is premised on the higher threshold of connection. Initially the high Court supported the lower threshold. In later decisions, whilst expressing support for the earlier decisions, in application the High Court favoured the higher threshold and at one point the rational business explanation. This trend appears to have been reversed with the most recent High Court decision which indicates substantive support for the earlier s 46 decisions.

Criminal penalties for contraventions of Part IV of the Trade Practices Act

In 2003 the Dawson Committee, commissioned by the Government, recommended that criminal penalties should be introduced for cartel conduct. The Government accepted this recommendation in principle and set up a working party to consider the implementation difficulties that had been identified in the Dawson Report. Nothing further was heard from the Government until February 2005 when the Government announced that it would introduce criminal penalties for serious cartel conduct. This paper evaluates the Government proposals and makes suggestions for their implementation.

Modification of tissue fatty acid composition in Murray cod (Maccullochella peelii peelii, Mitchell) resulting from a shift from vegetable oil diets to a fish oil diet.

The dynamics of fatty acid composition modifications were examined in tissues of Murray cod fed diets containing fish oil (FO), canola oil (CO) and linseed oil (LO) for a 25-week period and subsequently transferred to a FO (finishing/wash-out) diet for a further 16 weeks. At the commencement of the wash-out period, following 25 weeks of vegetable oil substitution diets, the fatty acid compositions of Murray cod fillets were reflective of the respective diets. After transfer to the FO diet, differences decreased in quantity and in numerousness, resulting in a revert to the FO fatty acid composition. Changes in percentages of the fatty acids and total accumulation in the fillet could be described by exponential equations and demonstrated that major modifications occurred in the first days of the finishing period. A dilution model was tested to predict fatty acid composition. In spite of a general reliability of the model (Y=0.9234X+0.4260, R²=0.957, P<0.001, where X is the predicted percentage of fatty acid; Y the observed percentage of fatty acid), in some instances the regression comparing observed and predicted values was markedly different from the line of equity, indicating that the rate of change was higher than predicted (i.e. Y=0.4205X+1.191, R²=0.974, P<0.001, where X is the predicted percentage of α-linolenic acid; Y the observed percentage of α-linolenic acid). Ultimately, using the coefficient of distance (D), it was shown that the fatty acid composition of fish previously fed the vegetable oil diets returned to the average variability of the fillet fatty acid composition of Murray cod after 70 or 97 days (LO and CO respectively).

Socio-economic inequalities in women`s fruit and vegetable intakes: a multilevel study of individual, social and environmental mediators

Objective: This study employed a multilevel design to test the contribution of individual, social and environmental factors to mediating socio-economic status (SES) inequalities in fruit and vegetable consumption among women. Design: A cross-sectional survey was linked with objective environmental data. Setting: A community sample involving 45 neighbourhoods. Subjects: In total, 1347 women from 45 neighbourhoods provided survey data on their SES (highest education level), nutrition knowledge, health considerations related to food purchasing, and social support for healthy eating. These data were linked with objective environmental data on the density of supermarkets and fruit and vegetable outlets in local neighbourhoods. Results: Multilevel modelling showed that individual and social factors partly mediated, but did not completely explain, SES variations in fruit and vegetable consumption. Store density did not mediate the relationship of SES with fruit or vegetable consumption. Conclusions: Nutrition promotion interventions should focus on enhancing nutrition knowledge and health considerations underlying food purchasing in order to promote healthy eating, particularly among those who are socio-economically disadvantaged. Further investigation is required to identify additional potential mediators of SES–diet relationships, particularly at the environmental level.

Global factor trade with differentiated factor prices and factor intensities

Relaxing the assumption of internationally identical factor intensity techniques in the HOV model creates two challenges. First, computing actual factor intensity techniques of different countries requires detailed input-output tables and factor usage data, which are not always available. Second, determinants of the factor intensity technique differences across countries need to be identified. This paper explores the role of relative factor price differences in the determination of factor intensity technique differences across countries and proposes an inferring method that infers factor intensity techniques of different countries based on relative factor price differences. The HOV model is then modified accordingly.

Commerce mondial des facteurs de production quand les prix des facteurs sont différenciés et les intensités dans l'intensité d'utilisation des facteurs différentes. Relaxer le postulat de techniques à intensité identique de facteurs de production d'un pays à l'autre dans un modèle Heckscher-Ohlin-Vanek (HOV) pose deux défis. D'abord, mesurer les intensités en facteurs des techniques en place dans les divers pays réclame des tableaux interindustriels détaillés et des données sur l'utilisation des facteurs qui ne sont pas toujours disponibles. Ensuite, il faut identifier les déterminants des différences d'intensités en facteurs des techniques d'un pays à l'autre. Ce mémoire explore le rôle des différences dans les prix relatifs des facteurs dans la détermination des différences d'intensité en facteurs d'un pays à l'autre, et propose une méthode qui permet d'inférer les différences d'intensité en facteurs des techniques des divers pays à partir des différences dans les prix relatifs des facteurs. Le modèle HOV est alors modifié en conséquence.

A 'Mobile' technology and waiting for the broadband 'horse trade'

Webcasting in Australia is currently the domain of national broadcasters, independent and community radio stations and the two leading football codes. This paper reports on the findings of a content analysis of 20 leading webcasters as to the content and genres they provide. In examining the factors affecting the 'slow' adoption of webcasting in Australia such as the absence ofa high speed broadband infrastructure, the paper analyses and how its various discourses were framed by the parties concerned, and how the clash of conflicting agendas shaped the negotiations between the main stakeholders, taking on the characteristics of a 'horse trade '. Thereafter, the paper critically examines how other technologies such as mobile phones and Pay TV has begun to take on webcasting, instead of waitingfor the major commercial broadcasters to do so or a new broadband network and a national broadband strategy to be implemented.

A structural events approach to examining long-term change in the Australian trade union movement, 1969-1996

Traditional studies of long-term change in trade union structure have predominantly focused on aggregate trends in union merger activity, in constructing explanations of change. This paper argues that our understanding of structural change in the Australian trade union movement would be better served by a structural events approach that examines the incidence of union formations, dissolutions, and breakaways, in addition to that of union mergers. In doing so, it outlines how these structural events can be identified and measured, and presents the preliminary findings from the methods application.
