Development of disease caused by Phytophthora cinnamomi in mature Xanthorrhoe australis

Over the past 30 years, heathland and open forest communities in south-eastern Australia dominated by Xanthorrhoea australis R.Br. have been severely affected by disease caused by Phytophthora cinnamomi Rands. The disease has caused a sharp decline in numbers of individuals within populations of X. australis; however, the etiology of the disease is unclear. The characteristics and disease symptoms induced by P. cinnamomi were analysed within nine mature X. australis plants that had been removed from the field. Seven plants showed typical disease symptoms that ranged from chlorotic leaves through to plant death. Plants showing disease symptoms had different numbers of infected roots, ranging from 0% in one dead plant, 40% infected roots in a plant showing yellowing of leaf tips and 67 and 86%, respectively, in two plants with severe chlorosis. There was variation within the roots, with some infected close to the stem while others were infected at more distal regions. Within stems of all plants, P. cinnamomi was difficult to isolate but was found in the desmium and stem apex and was associated with massive lesions within the central area of the stem. The symptoms of disease in X. australis are caused by a combination of damage to tissues of the roots and stem that may lead to a reduction in water and mineral transport throughout the plant.

Mature women and the New Zealand qualifications framework : realising the potential of recognising prior learning

Against a background of 'second-wave' lifelong learning in Aotearoa New Zealand a new framework for post-compulsory national qualifications was introduced. The resulting competency-based system was argued to present a number of benefits for mature women including flexibility in curriculum and delivery and portability across educational sectors. Competency-based education was to include provision for recognition of prior skills and knowledge gained in formal learning environments and the workplace as well as informal learning environments such as the home and the community. Such recognition was a significant factor in gaining support from women’s groups given the potential to recognize and value the domestic labour of women and the skills and knowledge that flow from it. This article explores the rhetoric around recognition of prior learning and discusses approaches to realise its potential. It then draws on research undertaken in Aotearoa New Zealand to suggest that the potential of recognition of prior learning is yet to be realised.

Towards the mature ePortfolio : some implications for higher education

Electronic portfolios [ePortfolios] are a recent addition to the language of higher education. Commencing with a summary of their role from EDUCAUSE, whose mission is to advance higher education by promoting the intelligent use of information technology, the distinctive characteristics of ePortfolios are outlined and salient differences from conventional portfolios in terms of process and outcomes are explored. Having considered the attributes of a mature ePortfolio, the paper focuses on pedagogical and technological issues for students and staff to move to mature ePortfolios. While accepting the valuable role ePortfolios can play in higher education, and that students increasingly come to the tertiary sector with expectations and experience that appear to warrant this approach, the paper concludes that decision making in this area is not yet adequately supported by research. Educators need to be open to the promise ePortfolios offer their students and staff but be aware of the implications for their adoption.

Mature workers, training and using TLM frameworks

Mature workers have been at the centre of policies aimed at encouraging higher workforce participation, longer working life and enhanced savings for retirement. Low mature age workforce participation rates reflect labour market withdrawal in the face of multiple barriers to participation for many. Their apparent voluntary joblessness conceals the fact that mature workers endure longer periods of unemployment, discrimination, redundancy and other barriers to employment (hence the drift to 'early retirement'). The policy dilemma is not just about addressing discrimination barriers, access to appropriate retraining or skills enhancement for mature workers, but what this tells us about lifelong learning as a means of managing and mitigating risk. The mismatch between work opportunities/skills shortages and the low education and skills base of many mature workers, means it is simplistic to think that working longer might be a short term way to address skills shortages; without an enormous investment in the current ageing cohort. Drawing on Transitional Labour Market (TLM) theory and European reform agendas, this article argues that the link between investment in lifelong education/ skills training and stronger labour market participation needs attention; not just for current cohorts of excluded or underemployed mature workers but to position strategically for future generations.

Older and wiser?: a comparison of the learning and study strategies of mature age and younger teacher education students

'Non-traditional' students are increasingly a part of university populations. This study examined differences between mature age and younger university students in their learning and study strategies as measured by the Learning and Study Strategies Inventory (LASSI). Subjects were 21 mature age and 104 younger teacher education students enrolled in The Bachelor of Teaching (Primary) course at the Royal Melbourne Institute of Technology. Significant correlations were found between the students' LASSI scores and both their self-reported level of global skill and their perceptions of how difficult the course was. There were significant differences between the two groups in terms of their learning and study strategies, with mature age students reporting themselves to be using effective strategies more often, on average, than younger students. The validity and implications of these findings in terms of student learning, support and instruction in study and learning and in predicting academic success are discussed.

Destinations that matter: associations with walking for transport

Associations between access to destinations and walking for transport were examined. Households (N=2650) were selected from 32 urban communities varying in walkability and socio-economic status. Respondents reported perceived proximity of destinations, transport-related walking, reasons for neighbourhood selection, and socio-demographic characteristics. Geographic Information Systems data defined objective measures of access to destinations. Measures of access to destinations were associated with transport-related walking. Associations depended on socio-demographic factors and type of destinations. Workplace proximity was the most significant contributor to transport-related walking, especially among women. Regular walking to work resulted in the accrual of sufficient physical activity for health benefits.

Consumer loyalty versus propensity to switch between providers in mature IT markets (the case of mobile phone market)

The example of the youth mobile phone market is used for pilot empirical testing of a model of consumers’ decision making, based on common features of consumer behaviour in mature markets of information and high technology products. Firstly, we discuss the key properties of mature high technology markets which affect market behaviour and strategies. These properties include: established customer and provider bases; the elements of both oligopolistic and monopolistic competition; very short product life cycle; considerable product differentiation; and using product quality, versioning and price discrimination as planning and marketing tools. Secondly, a model of consumers’ decision making in such markets is suggested on the assumption that a choice is to be made between the following options: to continue using the existing version of the product, to upgrade it with the current provider or to switch to another provider. Product price, quality characteristics, switching costs and network effects are demonstrated to be the variables affecting consumers’ decisions and therefore, these variables should be considered by competing providers when they choose production and marketing strategies. In conclusion, the results of the empirical study are discussed in the context of their possible application to other information and high technology markets.

Objective versus perceived walking distances to destinations : correspondence and predictive validity

Judgments concerning features of environments do not always correspond accurately with objective measures of those same features. Moreover, perceived and objectively assessed environmental attributes, including proximity of destinations, may influence walking behavior in different ways. This study compares perceived and objectively assessed distance to several different destinations and examines whether correspondence between objective and perceived distance is influenced by age, gender, neighborhood walkability, and walking behavior. Distances to most destinations close to home are overestimated, whereas distances to those farther away are underestimated. Perceived and objective distances to certain types of destinations are differentially associated with walking behavior. Perceived environmental attributes do not consistently reflect objectively assessed attributes, and both appear to have differential effects on physical activity behavior.

Competition in mature software markets

A theoretical framework is built for capturing properties of competition in mature monopolistic digital product markets. Based on an empirical study of the market of accounting software for small and medium enterprises, a consumer choice model is suggested, where a rational consumer is already using a particular version of a software package and is considering to chose from the following three options: either to continue using it, or to upgrade to a newer version of the product, or to switch to a competitive product. Consumer decision is justified by software quality, and network effects, under the price and switching costs constrains. A modified consumer demand function is used for the model, and theoretical conditions are analysed for choosing from one of the three above-mentioned options. The results are applicable to a wide range of digital products.

Examining the relationship between event owners and host destinations

The event sector has often come under the scrutiny of the public. A cursory glance at print and electronic media highlights some of the many negative attitudes social commentators and residents of host destinations have of special events. While there are a number of stakeholders of events, two entities which play a pivotal role in whether, when, and how events are delivered are the event governing bodies (or owners) and the host destinations. This paper examines the relationship between these two stakeholders. Research questions guiding this study are: Do event owners vary in their interactions with event destinations? Should event destinations be more discerning in their selection of the events they host? Can event destinations be more discerning in their selection of the events that they bid for?

While considerable research has focused on the relationship between event owners and host destinations during the event bidding process, this study aimed to explore the relationship more generally to provide greater insights into the event planning process. Thus, the study aimed to address a gap in knowledge about event marketing and management to understand motives for destinations to engage with event owners, and ultimately to enhance the quality of the event experience (for both attendees and non-attendees). A qualitative research approach was employed for this study, with elite interviews being the main data collection method.

The findings indicate that the relationship between event owners and host destinations can be highly problematic. A number of factors were identified as contributing to this situation, including the varying objectives that event owners have for their events; the way in which these objectives are congruent (or not) with host destinations objectives for events in their community; and the way in which a potential match or mis-match of objectives impacts a host destination’s ability to leverage an event. Overall, the researchers concluded that when there is disparity between the culture of the event owners’ organisation, and the social culture of the host destination, this situation is exacerbated. When event owners demonstrated empathy and an understanding of the host destination’s culture, and an understanding of the host destination’s aim for delivering an event, greater levels of perceived success are evident.

In the past, the bid process has been highly competitive. Host destinations have been at the mercy of event owners. However, the authors of this study indicate that as a result of this research, host destinations should be more discerning with regard to which event owners they ‘lie in bed with’ to ensure that the outcomes of the events are beneficial for their myriad stakeholders. It is acknowledged that the event planning and execution process is set within a political market square, as per Larson and Wikstrom’s (2001) suggestion, and that this context provides a fertile ground for research on this topic.

Competition in the mature markets of professional versus final consumer information products

Factors are explored of decision making in regard to buying and/or upgrading information products. Mature information product markets are considered. Comparing two cases - professional and final consumer information products - the decision making process is considered on the choice of product variant. We distinguish three groups of users according to their ultimate decisions to either not to upgrade the existing system, or to upgrade it with the existing provider, or to switch to another provider. Consumer decision is based on multiple characteristics of information product quality, network effects, price and switching costs, whereas producers have to compete not only with their competitors, but also with the previous versions of the own products. Based on the considered cases, differences in consumer priorities are discussed in the markets of professional versus final consumer information products.

Differences within and between travel preference, planned travel and choice behavior of Australians traveling to Asian and oversea destinations

This study seeks to examine differences in travel preference, travel intention and destination choice behavior of an aggregated set of Australian travelers. Additionally the study seeks to relate income, age, gender, life cycle and life style of Australians to the preference, planning and choice of Asian and overseas destinations. A large representative sample of 49,000 Australian respondents is utilized. Binomial regression is used to profile travelers to Asia and overseas in general. Specific significant variables and differences are highlighted. There are consistent relationships between travel preference, planning and choice and the set of independent variables of income, life cycle and life style. Age nor gender are not consistently related to travel planning or travel choice. It is apparent that a combination of demographics, e.g. age, income and life cycle, combined with life style will provide a more valuable basis for segmentation of Asian and overseas travel markets. The study aims to profile potential Australian tourists thereby making a contribution to tourism knowledge and market segmentation practice.
