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.

Quality of life and multiple sclerosis: comparison between people with multiple sclerosis and people from the general population

This paper evaluated the quality of life (QOL) of people with multiple sclerosis (MS) and people from the general population. Gender differences between the 2 groups of respondents and the influence of coping style on adjustment were also evaluated. The participants were 381 (144 males, 237 females) people with MS, and 291 (101 males, 190 females) people from the general population. The results demonstrated that people with MS experienced lower levels of QOL than people from the general population for both the objective and subjective dimensions of all domains (physical health, psychological adjustment, social relationships, environmental adjustment). All coping strategies (problem-focused, focusing on the positive, detachment, wishful thinking, seeking social support) were important predictors of QOL for both males and females with MS, with wishful thinking being the strongest predictor of poor QOL. These results are discussed in terms of the various factors that impact on QOL among people with MS, and the types of coping strategies that are most adaptive in improving the QOL of people with this illness.

A comparison study of cerebral protection using Ginkgo biloba extract and Losartan on stroked rats

It has been well documented that oxidative stress is involved in stroke. Currently, many neuroprotective strategies have been targeted at molecules that are able to act as an oxidant to intervene with free-radical mediated apoptosis in the ischemic penumbra. In particular, natural products which contain antioxidant properties have undoubtedly efficacious for stroke treatment. In the current study, therapeutic effects of Ginkgo biloba extract (EGb) against cerebral protection in Wistar rats underwent middle cerebral artery occlusion (MCAO) was evaluated. A comparison study was conducted by using Losartan, an antihypertensive drug. Gene expression levels of pro-apoptotic genes (AT2 receptor, Fas, Bax and Bcl-xS) have shown to have significant reduction by EGb- and Losartan-treated groups as compared to vehicle group. Significant reduction of immunoreactivity of protein production of these genes, together with least nuclear green fluorescence observed in TUNEL, EGb, as an antioxidant drug, is concluded to have potent and promising therapeutic effect for stroke treatment.

Instructional strategies integrating cognitive style construct : a meta-knowledge processing model

The overarching goal of this dissertation was to evaluate the contextual components of instructional strategies for the acquisition of complex programming concepts. A meta-knowledge processing model is proposed, on the basis of the research findings, thereby facilitating the selection of media treatment for electronic courseware. When implemented, this model extends the work of Smith (1998), as a front-end methodology, for his glass-box interpreter called Bradman, for teaching novice programmers. Technology now provides the means to produce individualized instructional packages with relative ease. Multimedia and Web courseware development accentuate a highly graphical (or visual) approach to instructional formats. Typically, little consideration is given to the effectiveness of screen-based visual stimuli, and curiously, students are expected to be visually literate, despite the complexity of human-computer interaction. Visual literacy is much harder for some people to acquire than for others! (see Chapter Four: Conditions-of-the-Learner) An innovative research programme was devised to investigate the interactive effect of instructional strategies, enhanced with text-plus-textual metaphors or text-plus-graphical metaphors, and cognitive style, on the acquisition of a special category of abstract (process) programming concept. This type of concept was chosen to focus on the role of analogic knowledge involved in computer programming. The results are discussed within the context of the internal/external exchange process, drawing on Ritchey's (1980) concepts of within-item and between-item encoding elaborations. The methodology developed for the doctoral project integrates earlier research knowledge in a novel, interdisciplinary, conceptual framework, including: from instructional science in the USA, for the concept learning models; British cognitive psychology and human memory research, for defining the cognitive style construct; and Australian educational research, to provide the measurement tools for instructional outcomes. The experimental design consisted of a screening test to determine cognitive style, a pretest to determine prior domain knowledge in abstract programming knowledge elements, the instruction period, and a post-test to measure improved performance. This research design provides a three-level discovery process to articulate: 1) the fusion of strategic knowledge required by the novice learner for dealing with contexts within instructional strategies 2) acquisition of knowledge using measurable instructional outcome and learner characteristics 3) knowledge of the innate environmental factors which influence the instructional outcomes This research has successfully identified the interactive effect of instructional strategy, within an individual's cognitive style construct, in their acquisition of complex programming concepts. However, the significance of the three-level discovery process lies in the scope of the methodology to inform the design of a meta-knowledge processing model for instructional science. Firstly, the British cognitive style testing procedure, is a low cost, user friendly, computer application that effectively measures an individual's position on the two cognitive style continua (Riding & Cheema,1991). Secondly, the QUEST Interactive Test Analysis System (Izard,1995), allows for a probabilistic determination of an individual's knowledge level, relative to other participants, and relative to test-item difficulties. Test-items can be related to skill levels, and consequently, can be used by instructional scientists to measure knowledge acquisition. Finally, an Effect Size Analysis (Cohen,1977) allows for a direct comparison between treatment groups, giving a statistical measurement of how large an effect the independent variables have on the dependent outcomes. Combined with QUEST's hierarchical positioning of participants, this tool can assist in identifying preferred learning conditions for the evaluation of treatment groups. By combining these three assessment analysis tools into instructional research, a computerized learning shell, customised for individuals' cognitive constructs can be created (McKay & Garner,1999). While this approach has widespread application, individual researchers/trainers would nonetheless, need to validate with an extensive pilot study programme (McKay,1999a; McKay,1999b), the interactive effects within their specific learning domain. Furthermore, the instructional material does not need to be limited to a textual/graphical comparison, but could be applied to any two or more instructional treatments of any kind. For instance: a structured versus exploratory strategy. The possibilities and combinations are believed to be endless, provided the focus is maintained on linking of the front-end identification of cognitive style with an improved performance outcome. My in-depth analysis provides a better understanding of the interactive effects of the cognitive style construct and instructional format on the acquisition of abstract concepts, involving spatial relations and logical reasoning. In providing the basis for a meta-knowledge processing model, this research is expected to be of interest to educators, cognitive psychologists, communications engineers and computer scientists specialising in computer-human interactions.

The branding of arts and culture : an international comparison

This paper explores the approach of arts and cultural organisations towards branding in Italy and Australia. Data were collected through extended interviews with general managers and marketing managers of 18 arts and cultural organisations, including museums, galleries, theatres and festivals of both countries. Through the analysis of the data collected, five initial elements emerged when seeking to classify the branding paradigms of the organisations, viz., the orientation of the brand management, the type of brand management, the level of customers’ involvement in the brand “idea”, the degree of consistency in branding and attitudes toward risk in branding. For this article, we focus on two particular elements, the orientation of the brand management and the degree of consistency in branding, as these elements have an important influence on how an arts organisation will strategically manage its brand.

On the basis of the assumption that branding is driven by different factors in different countries, the paper identifies two main paradigms/models of branding characterised by specific drivers: marketing tools and strategies in Australian arts and cultural organisations; history and tradition of the cultural product/offer in the Italian ones. What emerges in this study is that the importance of brands in the arts and culture context should not be underrated by arts and cultural managers. Both models (the Italian and the Australian) represent valid examples for managers to look at in relation to the brand management process.

Ecological and life-history factors influencing the evolution of maternal antibody allocation : a phylogenetic comparison

Maternally derived yolk antibodies provide neonates with immune protection in early life at negligible cost to mothers. However, developmental effects on the neonate's future immunity are potentially costly and thus could limit yolk antibody deposition. The benefits to neonatal immunity must be balanced against costs, which may depend on neonate vulnerability to pathogens, developmental trajectories and the immunological strategies best suited to a species' pace of life. We measured yolk antibodies and life-history features of 23 species of small Neotropical birds and assessed the evidence for each of several hypotheses for life history and ecological effects on the evolution of yolk antibody levels. Developmental period and yolk antibodies are negatively related, which possibly reflect the importance of humoral immune priming through antigen exposure, and selection to avoid autoimmunity, in species with a slower pace of life. There is also a strong relationship between body size and yolk antibody concentration, suggesting that larger species are architecturally equipped to produce and transfer higher concentrations of antibodies. These results suggest that developmental effects of maternally derived antibodies, such as imprinting effects on B-cell diversity or autoimmune effects, are important and deserve more consideration in future research.

Scapegoating, self-confidence and risk comparison : the functionality of risk neutralisation and lay epidemiology by injecting drug users

This paper investigates the competing rationalities of scientific and lay epidemiology and how the tension between the two impacts on the efficacy of health promotion messages for injecting drug users (IDUs). It proposes that behaviours, which may be difficult to understand when viewed at an individual level, are, in fact, rational within particular cultural contexts. The study used qualitative semi-structured interviews with 60 heroin users. A number of different types of risk neutralisation were observed in this group of interviewees, including: scapegoating, self-confidence and risk comparison. Interviewees commonly used lay epidemiology to justify and rationalise their risk neutralisation strategies. The paper provides concrete examples of the ways in which this group of IDUs neutralise risk through the use of these strategies. The findings illustrate how many of the psychological constructs surrounding the perception of risk which focus on individual behaviour are fundamentally simplistic and often unhelpful in understanding the behaviours of this group of people. It is concluded that some ‘risk’ behaviours are often functional and rational within the context of prohibitionist drug policies which create an environment in which the IDU often has little real agency to reduce the risks associated with their drug use.

Equilibration strategies in molecular dynamics simulation of polyethers

A comparison of the NVT and NVE ensemble simulations of tetraglyme showed that, in terms of energy, temperature and most of the structural features the results were very similar. However, major differences were observed in dynamic properties, ie in the mean square displacement and in the O--O distances. A fast equilibration method suitable for amorphous polymer systems is also detailed. This was accomplished by the reassignment of the velocity distribution to the particles, after the interruption of an NVE simulation.

A comparison of the classification of disparate malware collected in different time periods

It has been argued that an anti-virus strategy based on malware collected at a certain date, will not work at a later date because malware evolves rapidly and an anti-virus engine is faced with a completely new type of executable not as amenable to detection as the first was. In this paper, we test this idea by collecting two sets of malware, the first from 2002 to 2007, the second from 2009 to 2010 to determine how well the anti-virus strategy we developed based on the earlier set [14] will do on the later set. This anti-virus strategy integrates dynamic and static features extracted from the executables to classify malware by distinguishing between families. The resulting classification accuracies are very close for both datasets, with a difference of only 5.4%, the older malware being more accurately classified than the newer malware. This leads us to conjecture that current anti-virus strategies can indeed be modified to deal effectively with new malware.

This anti-virus strategy integrates dynamic and static features extracted from the executables to classify malware by distinguishing between families. We also perform another test, to investigate the same idea whereby we accumulate all the malware executables in the old and new dataset, separately, and apply a malware versus cleanware classification.

The resulting classification accuracies are very close for both datasets, with a difference of approximately 5.4% for both experiments, the older malware being more accurately classified than the newer malware. This leads us to conjecture that current anti-virus strategies can indeed be modified to deal effectively with new malware.

Comparison of the traditional problem-based learning format and larger, directed, independent study groups

 Problem based learning has been implemented as a pedagogical tool world-wide across a range of health professions since its inception at McMaster University, Canada, in 1969 (Neville & Norman, 2007). In addition to enhancing knowledge and understanding it is also claimed that PBL develops communication skills, encourages teamwork, sharing of information and respect for others, furthers problem solving skills, and allows students to assume responsibility for their own learning (Wood, 2003). However, the cognitive outcomes of PBL and traditional pedagogy (based on didactic teaching) are similar and hence widespread adoption of PBL has been questioned (see Colliver, 2000). Criticisms of PBL include its resource hungry nature, requiring, as it does, experienced tutors to facilitate .learning across several clusters of students dealing with the same problem. Given the actual and anticipated increase in numbers of medical students in Australia other strategies that retain the advantages of PBL, while minimising the demands on faculty, should now be explored. This paper reports our experience with a modification of the traditional PBL approach, termed PBLplus. This innovation was trialled in a regional clinical school, attached to a hospital, with a group of 19 graduate entry students, who had completed an integrated Year 1 / 2 of the MBBS. PBLplus involved allocating students from the whole class to three task directed groups. Groups had specified assignments to complete to facilitate learning across the whole class. A tutor listened to student presentations and provided an interactive presentation. Hence use of tutors was made more efficient, and faculty input was more specialised.

Children's physical activity and screen time : qualitative comparison of views of parents of infants and preschool children

Background
While parents are central to the development of behaviours in their young children, little is known about how parents view their role in shaping physical activity and screen time behaviours.

Methods
Using an unstructured focus group design, parental views and practices around children′s physical activity and screen time (television and computer use) were explored with eight groups of new parents (n=61; child age <12 months) and eight groups of parents with preschool-aged (3–5 year old) children (n=36) in Melbourne, Australia.

Results
Parents generally believed children are naturally active, which may preclude their engagement in strategies designed to increase physical activity. While parents across both age groups shared many overarching views concerning parenting for children′s physical activity and screen time behaviours, some strategies and barriers differed depending on the age of the child. While most new parents were optimistic about their ability to positively influence their child′s behaviours, many parents of preschool-aged children seemed more resigned to strategies that worked for them, even when aware such strategies may not be ideal.

Conclusions
Interventions aiming to increase children′s physical activity and decrease screen time may need to tailor strategies to the age group of the child and address parents′ misconceptions and barriers to optimum parenting in these domains.

Self-management needs during life transitions among younger people with type 2 diabetes : an Australian and Danish cohort comparison

The primary aim of this pilot study is to provide cross-cultural and detailed insights into how psychological and social factors impact on younger people with type 2 diabetes (T2DM) and self-management skille (20-40 years). The specific objectives are to: identify self-management strategies used by younger people with T2DM during life transitions in the period from 20-40 years of age; investigate participants' perception of self-management to identify the specific needs of younger people with T2DM. This research will provide health professionals with insights to the specific needs for young adults with T2DM and will add ground breaking innovative information by investigating cultural comparison between Australia and Denmark.

A comparison of Australian rural and metropolitan cardiovascular risk and mortality: the Greater Green Triangle and North West Adelaide population surveys

Objectives:
Cardiovascular (CVD) mortality disparities between rural/regional and urban-dwelling residents of Australia are persistent. Unavailability of biomedical CVD risk factor data has, until now, limited efforts to understand the causes of the disparity. This study aimed to further investigate such disparities.
