Do children's food preferences align with dietary recommendations?

Objectives: To examine how Australian children's reported everyday food preferences reflect dietary recommendations, and the impact of sociodemographic factors on these associations.

Design:  Cross-sectional survey.

Setting/subjects: Three hundred and seventy-one parents of children aged 2–5 years, recruited from three socio-economic groups in two Australian cities, completed a survey on their child's liking for 176 foods and drinks on a 5-point Likert scale in addition to demographic descriptors. Preferences were compared with the recommendations of the Dietary Guidelines for Children and Adolescents in Australia and the Australian Guide to Healthy Eating.

Results:  Foods in the Extra Foods (non-nutritious foods) and Cereals groups of the Australian Guide to Healthy Eating were highly liked (mean: 4.02 and 4.01, respectively), whilst foods in the Vegetables group were liked least (mean: 3.01). A large percentage of foods in the Cereals and Extra Foods groups were liked (64% and 56%, respectively) in contrast to the other food groups, especially Vegetables (7%). Children liked foods that were higher in sugar (r = 0.29, P < 0.0001) and more energy-dense (r = 0.34, P < 0.0001) but not those higher in saturated fat (r = 0.16, P = 0.03), total fat (r = 0.12, P = 0.12) or sodium (r = 0.10, P = 0.18). Sociodemographic variables (e.g. socio-economic status, parental education, children's age and sex) explained little of the variation in children's food preferences.

Conclusions:  Australian pre-school children's food preferences align with dietary guidelines in some respects, but not others. Interventions are needed to shift children's preferences away from non-nutritious foods that are high in energy density and sugar, and towards vegetables and fruits.

Social justice in Australian higher education policy : an historical and conceptual account of student participation

This article provides a synoptic account of historically changing conceptions and practices of social justice in Australian higher education policy. It maps the changes in this policy arena, beginning with the period following the Second World War and concluding with an analysis of the most recent policy proposals of the Bradley Review. Concurrently, it explores the different meanings ascribed to social justice, equity and social inclusion over this time span and what these have meant and will mean for students, particularly those from low socio-economic backgrounds. It concludes that a relational understanding of social justice – ‘recognitive justice’ – is yet to inform student equity policy in higher education, although this is now what is required in the context of the planned shift from mass to universal participation.

The emergent structure of feeling : what does it mean for critical educational studies and research?

Critical research in education is not what it used to be. It must now engage with a differently structured and globalized world with different social and material conditions for its peoples. This paper sets out to name the contemporary structure of feeling in which education researchers now work, particularly in terms of what now is to be the object of their educational theorizing and research and what are to be the intellectual resources brought to bear on such activity. The intention is to open up debate, recognizing that there are no easy answers and yet acknowledging the need for answers to be attempted. It is, therefore, an invitation premised on an optimism of the will to complement legitimate pessimism of the intellect. It concludes that a critical engagement with these matters demands a modernist/postmodernist, reconstructive/deconstructive reflexivity in the mobilizing of a new sociological imagination applied across the broad spectrum which is educational research.

Target will mean new approach

The Bradley report argues that we need a more "sophisticated approach" to equity. This includes a joined-up approach to TAFE and higher education. We need to think in terms of a tertiary system and to examine the pathways between them for their equity consequences.

Structuring in liquid alkanes between solid surfaces : force measurements and mean-field theory

Measurements have been made of the solvation forces between mica surfaces in the even-numbered n-alkanes from hexane to hexadecane. In all cases the force law is qualitatively very similar, characterized by a decaying oscillatory function of distance, as occurs for simple isotropic liquids. The spacing between successive minima in the force does not increase with carbon number, and is comparable to the width of a linear alkane molecule rather than its length or any average diameter. This suggests that the alkanes have some tendency towards a parallel orientation near the mica surfaces. The measurements give no indication of any strong repulsive component expected from mean-field theories of higher alkanes or polymers. The results of one such theory are presented, and the reasons for its failure to match the experimental data are discussed.

Molecular alignment in nematic liquid crystals : a comparison between the results of experiments at high pressure and predictions based on mean field theories

The effects of high pressure on molecular arrangment in liquid crystals were observed by optical measurements on two nematogens. It was possible to deduce how volume varies as a factor of temperature and pressure and how nematic order parameter changes under the influence of high pressure.

If a holistic approach to social work requires acknowledgement of religion, what does this mean for social work education?

There is growing recognition that promoting wellbeing requires a holistic approach to social work practice which includes understanding the role of religion in the lives of service users. This is reflected in a number of mentions of religion in the new code of ethics produced by the Australian Association of Social Workers. However, any consideration of whether religion has a place in social work should not only occur at the individual level, but also consider faith-based agencies. This paper considers the implications of this for social work education in respect of developing curriculum which acknowledges the religious dimension of the lives of many service users; skill development to enable social workers to broach issues of religion with service users; and working in or with faith-based agencies.

Good boards are strategic : what does that mean for sport governance?

To learn more about the governance of sport organizations, this study explored what meaning board members of national sport organizations (NSOs) attach to the concept of "strategic capability". In so doing, the inquiry also identified factors considered to constrain or enable board strategic function. This paper draws on a body of knowledge developed over 38 years on board strategic function, primarily from the commercial setting but also from the emerging body of work in the nonprofit and sport governance setting. Located within the interpretive research paradigm this study engaged a range of different qualitative methods including cognitive mapping and visual imagery. Working across two NSOs in New Zealand, four elements were generated that served as reference points in mapping out the meaning of a strategically able board. These were categorized as the need to have capable people, a frame of reference, facilitative board processes, and facilitative regional relationships.

Low actuation-voltage shift in MEMS switch using ramp dual-pulse

This paper proposes a ramp dual-pulse actuation-voltage waveform that reduces actuation-voltage shift in capacitive microelectromechanical system (MEMS) switches. The proposed waveform as well as two reported waveforms (dual pulse, and novel dual-pulse) are analyzed using equivalent-circuit and equation models. Based on the analysis outcome, the paper provides a clear understanding of trapped charge density in the dielectric. The results show that the proposed actuation-voltage waveform successfully reduces trapped charge and increases lifetime due to lowering of actuation-voltage shift. Using the proposed actuation-voltage waveform, the membrane reaches a steady state on the electrode faster.

The allometric relationship between mean fibre diameter of mohair and the fleece-free liveweight of Angora goats over their lifetime

As mean fibre diameter (MFD) is the primary determinant of mohair price we aimed to quantify the lifetime changes in mohair MFDas Angora goats aged and grew. Measurements were made over 12 shearing periods on a population of Angora goats representing the current range and diversity of genetic origins including South African, Texan and interbred admixtures of these and Australian sources. Records of sire, dam, birthweight, birth parity, liveweight, fleece growth and fleece quality were taken for does and castrated males (wethers) (n = 267 animals). Fleece-free liveweights (FFL_wt) were determined for each goat at shearing time by subtracting the greasy fleece weight from the liveweight recorded immediately before shearing. A restricted maximum likelihood growth curve model was developed for relating MFD to FFL_wt, age and other measurements.Asimple way of describing the results is:MFD= k (FFL_wt)b E; where k is a parameter that can vary in a systematic way with shearing(age), breed, weaning weight, sire, dam and individual; b is a parameter that is the same for nearly the whole study; and E are independent errors from a log-normal distribution. The analysis shows that ^b = 0.34, with s.e. (^b) = 0.021. Thus, mohair MFD was allometrically related to the cube root of FFLwt over the lifetime of Angora goats. However, the allometric proportionality constant differed in a systematic way with age at shearing, genetic strain, weaning weight, sire, dam and individual. For Texan-breed goats, MFD decreased as weaning weight increased (P = 0.00016). The findings indicate that management factors that affect liveweight and weaning weight have lifetime effects on mohair fibre diameter and therefore the value of mohair and the profitability of the mohair enterprise.
