Furthering the use of the strengths and difficulties questionnaire: reliability with younger child respondents

A sample of 917 children, aged 7 to 17 years, their parents, and their teachers each completed the appropriate version of the Strengths and Difficulties Questionnaire (SDQ), and 120 from each group did so again 2 weeks later. The results indicate that the SDQ demonstrates sound interinformant and test-retest reliability. Younger children, whose self-reports have not been assessed in previous studies, were reliable in their responding, although not as reliable as older children by these measures. However, the internal reliability of the various subscales, in particular, the peer problems subscale, is questionable for both older and younger child respondents. Overall the findings suggest that the SDQ's use may be extended cautiously to include self-report from younger children.

Secondary students` perceptions of a constructivist-informed teaching and learning environment for geometric optics

This article describes an exploration of a class of secondary school students perceptions of a constructivist informed teaching and learning environment for geometric optics. The students perceived the environment as one where they could freely express their ideas and be involved in activities. What was also apparent in this exploration was the students' preference for a classroom that involved small group discussions to whole class discussions that reflected a need for time to think about issues. They also have a preference for relevant, practical work that tests their ideas and a preference to have fewer notes that they construct themselves rather than notes dictated by the teacher.

Association of family environment with children's television viewing and with low level of physical activity

Objective: This study examined associations between the family environment and children's television (TV) viewing and likelihood of being low-active.
Research Methods and Procedures: In 2001, children were recruited from 19 primary schools in Melbourne, Australia. Parents completed a questionnaire about their child's TV viewing and the family environment. Children also completed a questionnaire and wore an accelerometer for 8 days. Movement counts were used to identify low-active children (lowest quartile). Data were analyzed in May 2004.
Results: The sample consisted of 878 children (mean age = 11.5 0.6 yrs). Multiple logistic regression revealed that socioeconomic status [adjusted odds ratios (AOR) = 0.4 boys], frequency families watched TV together (AOR = 2.0 boys), mothers' (AOR = 1.8 boys; AOR = 2.5 girls) and fathers' (AOR = 2.6 boys; AOR = 2.8 girls) TV viewing, and rules prohibiting TV during mealtimes (AOR = 0.6 boys; AOR = 0.6 girls) related to children watching TV 2 h/d. Variables associated with low-level physical activity included self-reported enjoyment of Internet use (AOR = 1.7 boys) and preference for watching TV (AOR = 2.3 girls), perception that mother uses computer a lot (AOR = 1.9 boys) and likes using the computer (AOR = 0.6 girls), fathers' reported computer/electronic games use (AOR = 1.7 girls), frequency families used computer together (AOR = 0.4 girls), rules that TV viewing must be supervised (AOR = 1.9 boys; AOR = 0.6 girls), and having pay TV (AOR = 0.6 boys) and electronic games at home (AOR = 2.6 boys).
Discussion: These findings suggest that the relationships between the family environment and TV viewing and low-level activity are complex and that these behaviors are distinct.

Australians' organic food beliefs, demographics and values

Purpose – To examine consumers' beliefs about organic foods and their relationship with socio-demographics and self-transcendence (universal, benevolence) personal values.

Design/methodology/approach – A random questionnaire-based mail survey of 500 Australian (Victorian) adults (58 per cent response) was used. The questionnaire included items on organic food beliefs, the importance of self-transcendence values as guiding principles in life, and socio-demographics. Statistical analyses included cross-tabulations of organic food beliefs by socio-demographics and multiple regression analyses of positive organic food beliefs with personal value and socio-demographic items as the independent variables.

Findings – The majority of participants believed organic food to be healthier, tastier and better for the environment than conventional food. However, expense and lack of availability were strong barriers to the purchasing of organic foods. Generally, women were more positive about organic food than men (e.g. women were more likely to agree that organic food has more vitamins/minerals than conventional food). The personal value factor related to nature, environment and equality was the dominant predictor of positive organic food beliefs, followed by sex. These predictors accounted for 11 per cent of the variance.

Research limitations/implications – A survey response bias needs to be taken into account. However, the response rate was adequate for reporting and differences in age and education between participants and the Victorian population were taken into account in data presentation. Future understanding of consumers' use of organic foods will require the inclusion of a fairly extensive set of potential influences.

Practical implications – Communication appeals based on psychographics may be a more effective way to alter consumers' beliefs about organic foods than those based on demographic segmentation.

Originality/value – To the best of one's knowledge, this is the first study to examine the relationship between personal values, socio-demographics and organic food beliefs in a random population sample. This study is relevant to producers, processors and retailers of organic food and those involved with food and agricultural policy.

Prediction intention to quit in the call centre industry: does the retail model fit?

Purpose – Models of workplace turnover are rarely assessed in contexts other than that in which they were developed. This reduces their generalizability and their usefulness in providing managers with guidance as to what they might do to reduce workers intentions to quit. The purpose of this study is to test a model derived from a study of shop floor retail salespeople in the call centre environment.

Design/methodology/approach – A questionnaire measuring the variables in the model was completed by 126 call centre representatives recruited from 11 call centres in Melbourne, Australia.

Findings – Although the model was supported, the interactions among the variables differed. In particular, stressors played a bigger, albeit indirect, role in the intention to quit.

Practical implications – Call centre managers need to consider carefully the aspects of the work environment that may be stressful. If appropriately addressed, turnover may be reduced, and productivity increased.

Originality/value – This paper demonstrates that the model of turnover derived from shop floor salespeople is generally robust in the call centre setting. It provides management of call centres with some guidance as to the factors associated with turnover and areas that can be addressed to reduce it.

Family food environment and dietary behaviors likely to promote fatness in 5-6 year-old children

Background: The family food environment (FFE) is likely to exert important influences on young children's eating. Examination of multiple aspects of the FFE may provide useful insights regarding which of these might most effectively be targeted to prevent childhood obesity.

Objective: To assess the associations between the FFE and a range of obesity-promoting dietary behaviors in 5–6-year-old children.

Design: Cross-sectional study.

Subjects: Five hundred and sixty families sampled from three socio-economically distinct areas.

Measurements: Predictors included parental perceptions of their child's diet, food availability, child feeding practices, parental modeling of eating and food preparation and television (TV) exposure. Dietary outcomes included energy intake, vegetable, sweet snack, savory snack and high-energy (non-dairy) fluid consumption.

Results: Multiple linear regression analyses, adjusted for all other predictor variables and maternal education, showed that several aspects of the FFE were associated with dietary outcomes likely to promote fatness in 5–6-year-old children. For example, increased TV viewing time was associated with increased index of energy intake, increased sweet snack and high-energy drink consumption, and deceased vegetable intake. In addition, parent's increased confidence in the adequacy of their child's diet was associated with increased consumption of sweet and savory snacks and decreased vegetable consumption. 

Conclusion:  This study substantially extends previous research in the area, providing important insights with which to guide family-based obesity prevention strategies.

The impact of teaching models, group structures and assessment modes on cooperative learning in the student design studio

As a result of ever diminishing teaching resources, an increasing number of architectural educators are setting group design projects, rather then spreading their time thinly over a large number of individual projects. This allows them to co-ordinate longer and more in-depth review sessions on a smaller number of assignment submissions. However, while the group
model may offer an authentic learning model by reflecting design in practice, the approach is not without its obvious shortcomings as a teaching archetype for the assessment of the knowledge and skill competencies of individual students. Hence, what is clear is the need for a readily adoptable andragogy for the teaching and assessment of group design projects.
The following paper describes the background, methodology and findings of a Strategic Teaching and Learning Grant funded research project carried out in the year 2005 at the School of Architecture and Building at Deakin University. The project aimed to inform a change of classroom/studio practice governing the assemblage, teaching and assessment of student design teams. The development through these changes of cooperative and student centred learning principles focused on effective design collaboration and fair assessment should, it will be argued, lead to an enhanced group-learning experience in studio, which will subsequently and ultimately enhance professional practice.

Ensuring quality during monitoring of the learning environment of government primary schools achieved through EUI-PDP for teachers and head teachers

A positive change in the learning environment in schools is visible through ongoing professional development of teachers and administrators. Monitoring the professional development program and providing support to teachers and administrators to transfer their learnings into the school environment ensures some measures of quality. Quality issues led to the launching of the Professional Development Program (PDP) for Primary School Teachers (PSTs) of Sindh by the United Educational Initiative (UEI), a consortium of five Governmental and Non-Governmental Organizations, working under the supervision of Education Sector Reform Assistance (ESRA). Implementation of the UEI-PDP in four districts of Sindh, is ensured by a team of professionals in each district. Recognising that capacity building of district education employees would improve the educational system in the country, 130 Master Trainers were selected, on merit, from the District Education Office for the training of 17,000 teachers and 3000 Head teachers/administrators over a period of two years. This paper developed the design of a Monitoring Process for a Professional Development Program for Primary School Teachers and Administrators. Data was collected through Pre/Post observations, Interviews, Questionnaires and Reports. Such tools make it possible for the monitoring teams to observe, to inquire further, and, along with the Managers, Master Trainers and School Support Team, seek to explain the progress of the program and take corrective action where indicated. Both formative evaluations as well as summative  evaluation techniques are utilized for evaluating the program. The monitoring process that assisted in formative evaluations is described. In order to assist in summative evaluation, data collected through the monitoring process was further developed to categorize the schools where teachers and head teachers are trained. It is hoped that the categorization of the schools may lead to further improvements in those schools which fall in the group for need improvement. It may also initiate further research as to reasons behind why some schools are in the good category and why others fall in the average category.

Validation of a food-frequency questionnaire assessment of carotenoid and vitamin E intake using weighed food records and plasma biomarkers: the method of triads model.

Background: Reliability or validity studies are important for the evaluation of measurement error in dietary assessment methods. An approach to validation known as the method of triads uses triangulation techniques to calculate the validity coefficient of a food-frequency questionnaire (FFQ).

Objective: To assess the validity of an FFQ estimates of carotenoid and vitamin E intake against serum biomarker measurements and weighed food records (WFRs), by applying the method of triads. Design: The study population was a sub-sample of adult participants in a randomised controlled trial of b-carotene and sunscreen in the prevention of skin cancer. Dietary intake was assessed by a self-administered FFQ and a WFR. Nonfasting blood samples were collected and plasma analysed for five carotenoids (a-carotene, b-carotene, b-cryptoxanthin, lutein, lycopene) and vitamin E. Correlation coefficients were calculated between each of the dietary methods and the validity coefficient was calculated using
the method of triads. The 95% confidence intervals for the validity coefficients were estimated using bootstrap sampling.

Results: The validity coefficients of the FFQ were highest for a-carotene (0.85) and lycopene (0.62), followed by b-carotene (0.55) and total carotenoids (0.55), while the lowest validity coefficient was for lutein (0.19). The method of triads could not be used for b-cryptoxanthin and vitamin E, as one of the three underlying correlations was negative.

Conclusions: Results were similar to other studies of validity using biomarkers and the method of triads. For many dietary factors, the upper limit of the validity coefficients was less than 0.5 and therefore only strong relationships between dietary exposure and disease will be detected.

Functional group conflict in information systems development

This paper discusses how interpersonal conflict between IS developers and clients can disrupt IS projects.  It is suggested how potential problems can be avoided by getting the 'soft' factors right which can lead to improvements in information systems development (ISD) processes.  However little is being done in most organisations to review success from this perspective.  Measurement of ISD quality tends to favour the product rather than the human drivers that influence the development of the product.  Several ideas are put forward that can be used to resolve conflict and tp better involve stakeholders in the ISD process.

Using online technologies: does culture matter?

There has been an increase in the number of international students studying information technology programmes in Australia. There is little information about how this group uses online technologies. The overall aim of this research was to investigate how students use online technologies and teaching resources. A secondary aim was to determine whether there were any differences between international and local students using the online environment. The study consisted of two parts: an online survey  questionnaire and an analysis of the student’s use of the online environment. The overall results showed very little difference between two cohorts and that these results would be enhanced by further research into educational and cultural backgrounds.

Security in the online e-learning environment

This paper addresses the role of security in the collaborative e-learning environment, and in particular, the social aspects of security and the importance of identity. It represents a case study, completed in Nov 2004, which was conducted to test the sense of security that students experienced whilst using the wiki platform as a means of online collaboration in the tertiary education environment. Wikis, fully editable Web sites, are easily accessible, require no software and allow its contributors (in this case students) to feel a sense of responsibility and ownership. A comparison between two wiki studies will be made whereby one group employed user login and the other maintained anonymity throughout the course of the study. The results consider the democratic participation and evolution of the work requirements over time, which in fact ascertains the nonvalidity of administrative identification.

Problem-based learning in an online environment

This study describes the investigation of postgraduate students of mixed age and gender distributed across several Australian states as well as off shore who were juggling study with workplace demands. As face to face meeting was impossible because of the geographical distribution of the group members and because the course communication was centred on an online conference space, a small group space was established for each group for the purpose of completing the problem-based learning task. This paper provides a detailed description of the group dynamics and interactive processes required to negotiate an online problem-based learning task. It will also suggest ways to improve the collaborative learning potential of the online environment through well structured and meaningful activities.

Greening political risk: transnational advocacy networks and the World Bank Group

Significant increases in direct private investment in developing countries in recent decades have also led to increased interest in political risk insurance. Of importance to transnational advocacy networks are the environmental and social impacts of guaranteeing loans for private sector projects in developing countries with weak or no social or environmental safeguards. This article examines how transnational advocacy networks have attempted to influence political risk insurers to become sustainable development guarantors through a case study of the World Bank Group’s Multilateral Investment Guarantee Agency (MIGA). Analyzing how advocacy networks influenced MIGA’s projects, policies, and accountability institutions enables greater understanding of how to ‘politicize finance.’ It also assesses the likelihood of shaping political risk insurance identities to become sustainable development guarantors. The outcomes of such an analysis however, question the extent to which politicizing finance necessarily leads to further greening of the international development lending process.

The academic acclimatisation difficulties of international students of the built environment

Teaching models common to Australasia can be antithetical to those of its Asian neighbours. Australasian andragogy is a bottom-up student-centred mode of knowledge transmission promoting extroverted learning styles, whilst in Asia andragogy is commonly a top-down teacher centred model promoting introspective learning. Yet these teaching styles are in opposition to the cultural-systems attributed to Asia and the West. Such socio-cultural differences are recognised in this research as contributing to the difficulties international Built Environment undergraduates experience when asked to learn in multi-disciplinary collaborative teams. This paper presents the initial stages of a study currently running as a reflexive research program aimed at resolving these learning difficulties. The primary aim of this program is to inform a new culturally inclusive andragogy for design teaching. The outcome of the research questions are addressed through a triangulated analysis including: the formative appraisal of student satisfaction through questionnaires; the summative evaluation of student achievement through the analysis of grades and the assessment of knowledge and skills gained through the measure of student design projects; and illuminative evaluation through focus group discussions and the observation of tutorials.
