An evaluation of the role and impacts of alien finfish in Asian inland aquaculture

Asia dominates global aquaculture production accounting for over 80% of the total and the mainstay in Asian aquaculture is finfish. Over the years, Asia has experienced a number of inter-continental and intra-continental transfers/introductions/translocation of finfish species, between nations and watersheds, beyond their natural range of distribution, primarily for aquaculture development. In this article all such species are referred to as alien species. An attempt is made to evaluate the importance of the production of alien species in selected Asian nations, using statistics of the Food and Agriculture Organization. Also, negative effects, if any, based on literature surveys, of alien species in relation to displacement of indigenous species, and on biodiversity and/or genetic diversity together with associated pathogen transfers are evaluated. The major alien species, based on their significance to Asian inland aquaculture considered, are the tilapias, catfish, Chinese and Indian major carps and common carp. It is estimated that currently alien species account for nearly 12% of the cultured finfish production (2.6 million tonnes) in Asia, valued at US$ 2.59 billion, and the contribution exceeds 40% when Asian countries excluding China are taken into consideration. Inland finfish aquaculture in some Asian nations, such as Indonesia and the Philippines, is predominated by alien species, and in some others, e.g. Bangladesh and India, the contribution from alien species has been increasing steadily. It is suggested that overall alien finfish species have done little ecological harm to native flora and fauna. However, in the wake of increasing anthropogenic development taking place in watersheds the resulting environments are often made unconducive to indigenous species but not to some alien species, thereby potentially and indirectly making the latter invasive.

Identifying learning preferences in vocational education and training classroom settings

This research was designed to assess whether teachers and trainers of vocational learners noted and valued differences in individual learning preferences and, if so, how those differences were observed in natural classroom, workshop or other formal learning settings. Data were collected from six vocational education and training (VET) learning sites and included a quantitative questionnaire component and an interview component. The questionnaire data were generated from 160 VET teachers and trainers, and there were 13 interviews with individual teachers. The data show that teachers do make observations of style and preference differences and do respond to those differences. They are pragmatic in the ways that they make the observations and conclusions from them, and they organise their ideas about preferences into those to do with mode of delivery and those to do with learning context. Using these observations and their organisation of them, teachers also continuously modify preconceptions they have about individual learners and groups of learners, and those modifications influence teachers' responses to learners.

Part-time research students: the`reserve army` of research students for universities

Over the past twenty years, in Australia, there has been a steady growth in the numbers of part-time research students. However, they have generally been invisible in government policy on research training, and have rarely been the focus of specific treatment in universities, where the full-time scholarship-holder is taken as the norm. Yet, these are people who often undertake their research in their workplaces on problems germane to their work. They do so with relatively less ‘drain on the public purse’ and they are well-placed to ensure their research has effect. This paper suggests that this ‘reserve army’ of research labour—part-time research students—could benefit from the integration of the perspectives that have driven other aspects of adult education with those, often economic rationalist perspectives, that have driven research training policy. In this way, government policy-makers may appreciate that this ‘reserve army’ provides good value, and universities may shape their research training policies and practices to provide support, infrastructure and supervision that matches the needs and contexts of part-time students, and which facilitates ‘technology transfer’ and links between universities and industries and the professions.

Elearning: 40 years of evolution?

Cun-ent rhetoric around the use of 'eLearning' in Higher Education relates particularly to Internet-based flexible eLearning programs that focus on sustaining particular communities of practice. In this paper we argue that this contempormy view of what eLearning comprises arises from a lack of historical perspective on what the focus of educational eLearning programs has been over the past 40 years. Contemporary descriptions of eLearning as a 'new mode of learning' are fallacious and ignore its 40-year evolution from 1: 1 localised didactic models (both constmctivist and behaviourist) to many-to-many distributed social-constmctivist learning models. In addition, the historic divide between Education and Training has led to both the concurrent development of different notions, foci, and labels for technology-enhanced learning in different contexts and situations, and different conceptual origins arising in acquisitive and participatory learning metaphors. We argue that a more inclusive and historically aware conceptual framework is needed to be able to accurately describe what the full repertoire 'eLearning' really embraces

Effectiveness of fire safety education in primary school children

Young children have been identified as a high-risk group in relation to fire-related deaths because of their limited ability to understand the intinsic dangers of fire, to foresee the consequences of playing with fire, or to manage a fire if it were to become out of control.  Children are also not equipped to respond in a meaningful way in the event of a fire.  It is therefore essential that fire safety education be imparted to children in an effective manner so as to equip them to deal with a fire efficiently.  The objective of the present study was to evaluate the 'Fire Ed' program conducted by the Melbourne Metropolitan Fire Brigade for primary school children to determine whether exposure to the curriculum will influence children's knowledge of fire safety behaviours.  Although the program has numerous positive features, its overall effectivenedd has not been evaluated.  It was hypothesised that: a) children will not be aware of essential fire safety information prior to attending the 'Fire Ed' program, and b) children will display a significant gain in fire safety knowledge after participation in the program.  Sixty children from six primary schools participated in the study and they were tested on their level of fire safety knowledge prior to and after partcipation in the 'Fire Ed' program.  Results show that the children's knowledge of fire safety procedures improved significantly after participation in the program when tested after three weeks, however, when their knowledge was examined after five weeks, a significant decline was seen.  The findings show that regular evaluations of fire safety programs are required and that they could be improved by considering the different stages of cognitive development in children.

Australian gp's preferences for education about depression and related disorders

OBJECTIVE: To Investigate Australian general practitioners' experiences of accessing education about depression and their preferences for future education on depression and related disorders.
METHOD: Six hundred and eight anonymous surveys were distributed to GPs through 52 rural and urban divisions of general practice; 420 were retumed.
RESULTS: Educational formats involving direct contact with people having mental health expertise were highly valued. Distance education and web based technologies were least used. In the previous year, women and older GPs had spent more time on education about depression. Most intended to undertake more such education in the future and said that education in psychosocial strategies would be very useful. General practitioners' attitudes to further education about depression were influenced by their gender, practice location, and their previous mental health training.
DISCUSSION: More face-to-face training may be desirable to take advantage of GPs' willingness to spend more time on education about depression and related disorders.

Flexible delivery and student attrition in the vocational education and training sector: case studies of students who dropped out

Government policy in Australia is increasingly encouraging training organisations in the Vocational Education and Training (VET) sector to adopt flexible delivery approaches. This policy shift is supported by key VET stakeholders including Industry Training Advisory Boards. A recurring theme in VET policy documents is an apparent confidence that flexible delivery can meet the diverse needs of individual learners while at the same time providing cost savings. Yet evidence is emerging that Australian VET learners are not typically ready for flexible delivery, and this lack of readiness is reflected in high attrition rates and low pass rates in many flexibly delivered courses. One research project found that over 70% of learners in the Australian VET sector do not have the learning capabilities required to be ready for flexible delivery. A recent review of the module outcomes achieved by VET students nationally found that students studying by external/correspondence and self-paced unscheduled modes had lower module completion rates than students studying by other delivery strategies.

Research on student progress in flexible delivery within the Australian VET sector has largely been quantitative. That research provides useful statistical data on completion and attrition rates for various modes of delivery, but does not explore the reasons underlying the high attrition rates found in flexible delivery. The qualitative research that is available tends to focus on students who successfully complete their courses, not on those who withdraw. As a result, the Australian literature on flexible delivery in the VET sector is lacking in-depth qualitative information about students who enrol in courses but do not complete. In comparison, the broader literature on distance education and flexible delivery in other educational sectors offers some useful insights into student attrition, and can be can be used to inform research into attrition within the Australian VET sector.

This paper reports on aspects of a research project that followed up six adult learners who enrolled in VET courses but who either failed assessment or withdrew. The research project presented the students’ stories in the form of narrative case studies, focussing on the detailed examination of the barriers that each student experienced, and analysing these barriers in relation to issues raised in the literature. This paper reports on two particular themes that emerged from that research project. The literature on distance education and flexible delivery argues that:


· student dropout is often not determined by a single factor, but by the interaction of a number of factors that build up over time;

· students who experience difficulties when studying by flexible delivery can often be reluctant to access the support that is available to them.

This paper uses these themes as a point of reference in presenting the stories of some of the students who participated in the research project.

A rural model for delivering regional continuing nurse education by videoconference : a pilot project

Background : The South West Alliance of Rural Health (SWARH) is an alliance of 33 health care agencies scattered across South West Victoria over a total area of approximately 46 000 square kilometres. SWARH was established to develop and install information technology (IT) infrastructure, hardware and software for all acute public hospitals in the region. The Rural Intercampus Learning Environment Project (March 2003-March 2004) piloted the use of the SWARH regional area IT network to deliver a program of continuing education to Division 1 registered nurses, utilising the expertise of local health professionals. The study was funded by the Department of Human Services, Victoria.

Aims & rationale/Objectives : Establish partnerships for multi-site delivery of programs.
Develop existing educational programs and resources for video and intranet delivery (including IT training and change management).
Collaboratively deliver educational programs utilising SWARHnet to six rural sites.
Explore issues related to the use of the technology in continuing education for rural nurses and the implications for practice.

Methods : Key informant interviews, paper-based audits, and focus groups informed the development of the schedule of the program. Session participants completed a 2-page evaluation questionnaire.

Principal findings : Participants must own the process.
Videoconferencing should be considered an adjunct to traditional education programs.
Videoconferencing most suitable for short education sessions as opposed to full-day workshops.
IT problems are unpredictable and frustrating for all concerned.
IT awareness/training of staff is essential.

Implications : The project proposes a model for coordinating and delivering regional continuing education which has been shown to improve access to education programs across multiple sites. It provides a sustainable organisational framework for the program, which could be applied in continuing professional education programs of other rural health professions, such as dentistry, medicine, allied health and pharmacy.

Managing behavioural symptoms of dementia : Effectiveness of staff education and peer support

This study was designed to investigate the impact of staff education on the behaviour and quality of life of residents with dementia and on staff members' attitudes about working with people with dementia and level of burnout. Staff from three aged care facilities participated in the study (n = 52). These facilities were randomly assigned to one of two intervention groups or a control group. Staff assigned to the intervention groups received an eight-week behaviourally-based programme. Staff from one aged care facility also participated in a peer support group designed to reinforce educational material and facilitate positive changes among staff members. Behavioural symptoms displayed by residents (n = 76) in each of the facilities were also assessed. Assessments were conducted at pre-intervention, post-intervention, three- and six-month follow-up. The results of this study indicated that education or peer support was not associated with an improvement in resident behaviour or quality of life. Education or peer support also did not impact on staff members' level of burnout. There was, however, a change in staff members' attitudes about working with people with dementia. Possible explanations for these findings and implication for further research are considered.

Can a disease-specific education program augment self-management skills and improve Health-Related Quality of Life in people with hip or knee osteoarthritis?

Background: Patient education and self-management programs are offered in many countries to people with chronic conditions such as osteoarthritis (OA). The most well-known is the disease-specific Stanford Arthritis Self-Management Program (ASMP). While Australian and international clinical guidelines promote the concept of self-management for OA, there is currently little evidence to support the use of the ASMP. Several meta-analyses have reported that arthritis self-management programs had minimal or no effect on reducing pain and disability. However, previous studies have had methodological shortcomings including the use of outcome measures which do not accurately reflect program goals. Additionally, limited cost-effectiveness analyses have been undertaken and the cost-utility of the program has not been explored.

Methods/design: This study is a randomised controlled trial to determine the efficacy (in terms of Health-Related Quality of Life and self-management skills) and cost-utility of a 6-week group-based Stanford ASMP for people with hip or knee OA.

Six hundred participants referred to an orthopaedic surgeon or rheumatologist for hip or knee OA will be recruited from outpatient clinics at 2 public hospitals and community-based private practices within 2 private hospital settings in Victoria, Australia. Participants must be 18 years or over, fluent in English and able to attend ASMP sessions. Exclusion criteria include cognitive dysfunction, previous participation in self-management programs and placement on a waiting list for joint replacement surgery or scheduled joint replacement.

Eligible, consenting participants will be randomised to an intervention group (who receive the ASMP and an arthritis self-management book) or a control group (who receive the book only). Follow-up will be at 6 weeks, 3 months and 12 months using standardised self-report measures. The primary outcome is Health-Related Quality of Life at 12 months, measured using the Assessment of Quality of Life instrument. Secondary outcome measures include the Health Education Impact Questionnaire, Western Ontario and McMaster Universities Osteoarthritis Index (pain subscale and total scores), Kessler Psychological Distress Scale and the Hip and Knee Multi-Attribute Priority Tool. Cost-utility analyses will be undertaken using administrative records and self-report data. A subgroup of 100 participants will undergo qualitative interviews to explore the broader potential impacts of the ASMP.

Discussion: Using an innovative design combining both quantitative and qualitative components, this project will provide high quality data to facilitate evidence-based recommendations regarding the ASMP.

The Health Education Impact Questionnaire (heiQ): An outcomes and evaluation measure for patient education and self-management interventions for people with chronic conditions

Objective: This paper describes the development and validation of the Health Education Impact Questionnaire (heiQ). The aim was to develop a user-friendly, relevant, and psychometrically sound instrument for the comprehensive evaluation of patient education programs, which can be applied across a broad range of chronic conditions.

Methods: Item development for the heiQ was guided by a Program Logic Model, Concept Mapping, interviews with stakeholders and psychometric analyses. Construction (N = 591) and confirmatory (N = 598) samples were drawn from consumers of patient education programs and hospital outpatients. The properties of the heiQ were investigated using item response theory and structural equation modeling.

Results: Over 90 candidate items were generated, with 42 items selected for inclusion in the final scale. Eight independent dimensions were derived: Positive and Active Engagement in Life (five items, Cronbach's alpha (α) = 0.86); Health Directed Behavior (four items, α = 0.80); Skill and Technique Acquisition (five items, α = 0.81); Constructive Attitudes and Approaches (five items, α = 0.81); Self-Monitoring and Insight (seven items, α = 0.70); Health Service Navigation (five items, α = 0.82); Social Integration and Support (five items, α = 0.86); and Emotional Wellbeing (six items, α = 0.89).

Conclusion:The heiQ has high construct validity and is a reliable measure of a broad range of patient education program benefits.

Practice Implications: The heiQ will provide valuable information to clinicians, researchers, policymakers and other stakeholders about the value of patient education programs in chronic disease management.

Six year follow-up of students who participated in a school-based physical activity interventions : a longitudinal cohort study

Background
The purpose of this paper was to evaluate the long-term impact of a childhood motor skill intervention on adolescent motor skills and physical activity.

Methods
In 2006, we undertook a follow-up of motor skill proficiency (catch, kick, throw, vertical jump, side gallop) and physical activity in adolescents who had participated in a one-year primary school intervention Move It Groove It (MIGI) in 2000. Logistic regression models were analysed for each skill to determine whether the probability of children in the intervention group achieving mastery or near mastery was either maintained or had increased in subsequent years, relative to controls. In these models the main predictor variable was intervention status, with adjustment for gender, grade, and skill level in 2000. A general linear model, controlling for gender and grade, examined whether former intervention students spent more time in moderate-to-vigorous physical activity at follow-up than control students.

Results
Half (52%, n = 481) of the 928 MIGI participants were located in 28 schools, with 276 (57%) assessed. 52% were female, 58% in Grade 10, 40% in Grade 11 and 54% were former intervention students. At follow-up, intervention students had improved their catch ability relative to controls and were five times more likely to be able to catch: ORcatch = 5.51, CI (1.95 – 15.55), but had lost their advantage in the throw and kick: ORthrow = .43, CI (.23 – .82), ORkick = .39, CI (.20 – .78). For the other skills, intervention students appeared to maintain their advantage: ORjump = 1.14, CI (.56 – 2.34), ORgallop = 1.24, CI (.55 – 2.79). Intervention students were no more active at follow-up.

Conclusion
Six years after the 12-month MIGI intervention, whilst intervention students had increased their advantage relative to controls in one skill, and appeared to maintain their advantage in two, they lost their advantage in two skills and were no more active than controls at follow up. More longitudinal research is needed to explore whether gains in motor skill proficiency in children can be sustained and to determine the intervention characteristics that translate to subsequent physical activity.

Learning 'through' or learning 'about'? The ridiculous and extravagant medium of opera : Gardner's multiple intelligences in pre-service teacher education

In recent years, pre-service teacher education has attempted to incorporate into programs an understanding of Gardner’s theory of multiple intelligences as it applies to schools. In this paper the tension between ‘learning about’ multiple intelligences and ‘learning through’ multiple intelligences supports Gardner’s (1993) distinction between ‘understanding’ and ‘coverage’. This paper examines the use of the performing arts in the professional studies component of our teacher education program. During 2002 at The University of Melbourne, a group of education students were offered the opportunity to develop an opera in order to learn about assessment and curriculum. Thirty-seven of the students volunteered to be involved and over a period of six months met this challenge. Our action research study asked two critical questions. To what extent is the understanding of multiple intelligences by pre-service teachers improved by ‘learning through’? Can pre-service teachers address fundamental issues in curriculum and assessment through the development of a performance? This experience would be of value to other teacher educators.

The influence of Sport Education on student motivation in physical education

Background: Physical educators are faced with trying to provide motivating and enjoyable experiences in physical education. Sport Education is an instructional model that aims to provide positive motivational sport experiences by simulating the features of authentic sport. Research support for Sport Education is positive, however, the effects on student motivation and the motivational climate are not well understood.

Purpose: To investigate the influence of the Sport Education model on student motivation (intrinsic/extrinsic motivation, goal orientations, and perceived motivational climate) in secondary physical education.

Setting: Six classes were selected according to teacher and class availability in the sports of soccer, hockey, and football codes in a co-educational government school.

Participants: Participants were 115 (male = 97, female = 18) Year-8 students (aged 13-14 years), in a Sport Education condition (n = 41) and a Traditional condition (n = 74).

Measures: At pre- and post-test, all participants completed three questionnaires: the Intrinsic Motivation Inventory, the Task and Ego Orientation in Sport Questionnaire, and the Perceived Motivational Climate in Sport Questionnaire.

Intervention: Participants completed either a Sport Education condition or a Traditional condition for one double period (100 minutes) one day per week for 10 weeks (Sport Education condition) or for five weeks (Traditional condition). The Sport Education condition incorporated six distinctive features: seasons, affiliation, formal competition, record keeping, festivity, and a culminating event. The Traditional condition used whole-group instruction led by the teacher.

Research design: The study used a non-equivalent control group design with pre- and post-test procedures. The independent variable was teaching condition and the dependent variable was student motivation (assessed by intrinsic motivation, goal orientations, and motivational climate). The groups were already established and selected for convenience purposes.

Data collection and analysis: Participants completed pre-test measures and then participated in their pre-established classes. Post-test measures were completed in the last class in each condition. A reliability analysis on measures was conducted using Cronach's alphas. A pre-test manipulation check was performed to check for any initial differences in motivation. To compare the difference in changes between conditions on motivation, a series of 2 times 2 repeated measures analyses of variance were conducted. A comparison of the relationship between motivation measures was conducted using Pearson's product moment correlation coefficients.

Findings: There was a significant difference between the conditions on changes in perceived competence, task orientation, and mastery climate, with the Traditional condition decreasing significantly from pre- to post-test compared with the Sport Education condition. There were no significant differences on interest/enjoyment, effort/importance, pressure/tension, ego orientation, or performance climate. A mastery climate was positively related to task orientation and intrinsic motivation and a performance climate was related to ego orientation.

Conclusions: The Sport Education condition was more successful in maintaining high levels of intrinsic motivation, task orientation, and mastery climate than the Traditional condition. That is, the Traditional condition was associated with a decrease in adaptive aspects of motivation for students, whereas the Sport Education condition maintained existing levels of motivation.
