Influences on consumption of soft drinks and fast foods in adolescents

Soft drink and fast food are energy dense foodstuffs that are heavily marketed to adolescents, and are likely to be important in terms of risk of obesity. This study sought to examine the influences on soft drink and fast food consumption among adolescents as part of a cross-sectional survey of 2,719 adolescents (aged 11-16) from 93 randomly selected schools in New South Wales, Australia. Students provided information on soft drink and fast food consumption, and responded to statements examining influences over consumption. Over half of the boys and more than one third of the girls reported drinking soft drink daily, and consumption peaked in Grade 8 students. A quarter of students reported choosing soft drinks instead of water or milk, and around 40% agreed that soft drink was usually available in their homes. Availability in the home and drinking soft drinks with meals was most strongly associated with consumption in all age groups. Fast food consumption was higher among boys than girls in all age groups. Convenience and value for money yielded the strongest associations with fast food
consumption in boys, while preferring fast food to meals at home and preferring to “upsize” meals were most strongly associated with consumption in girls. Interventions to reduce consumption of soft drinks should target availability in both the home and school environment by removing soft drinks and replacing them with more nutritive beverages. Fast food outlets should be encouraged to provide a greater range of healthy and competitively priced options in reasonable portions.

Influence of the blink interval on tear meniscus height in soft contact lens and nonlens wearers

Purpose: Tear meniscus height (TMH) is an indirect measurement of tear film volume. This study investigated the temporal changes in the TMH during the blink interval in the morning (8–9 am) and at the end of the day (5–6 pm) in both soft contact lens (CL) and nonlens wearers (NLW).

Methods: Fifty participants (25 CL; 25 NLW) were evaluated for their subjective symptoms, TMH, noninvasive break up time, and bulbar hyperemia at the am and pm visits on the same day. The TMH was measured at set intervals between 2 and 15 sec during the blink interval, using an optical coherence tomographer.

Results: The NLW group revealed no changes in a variety of symptoms during the day, whereas the CL group reported an increase in dryness (P=0.03) and grittiness (P=0.02) over the day. For both groups, the TMH and calculated tear meniscus volume revealed lower values immediately after the blink and increased progressively afterwards, mainly due to reflex tearing. The am tear meniscus volume values tended to be higher than the pm values for both groups, but this was not significant (NLW P=0.13; CL P=0.82). Noninvasive break up time deteriorated during the day for both groups but was only significant for the CL group (P=0.002), whereas bulbar hyperemia revealed no statistically significant change for either group.

Conclusions: Reflex tearing may play a substantial role in the TMH differences observed over the blink interval. Standardization of the time when a TMH measurement is performed will be valuable in comparing tear film clinical studies.

Measurement of the refractive index of soft contact lenses during wear

Purpose: To determine whether the refractive index (RI) of a soft contact lens can be evaluated using refractometry while the lens remains on the eye and to compare this with more traditional ex vivo RI measurements.

Methods: A slitlamp apparatus was modified to incorporate a customized Atago hand refractometer. With a double-masked study design, nine adapted symptomatic soft contact lens wearers wore a contact lens in each eye (lotrafilcon B and etafilcon A) in a randomized order. In vivo RI was determined from the relative Brix scale measurements immediately after lens insertion and after 1 and 10 hr of lens wear. Ex vivo refractometry was performed after 10 hr of lens wear for comparison. Means ± standard errors of the means are reported.

Results: In vivo RI values at baseline were 1.422 ± 0.0004 (lotrafilcon B) and 1.405 ± 0.0021 (etafilcon A); after 1 hr of lens wear, values were 1.423 ± 0.0006 and 1.408 ± 0.0007, respectively; and after 10 hr of lens wear, values were 1.424 ± 0.0004 and 1.411 ± 0.0010, respectively. Ex vivo RI values at the end of the 10 hr wearing period were 1.424 ± 0.0003 (lotrafilcon B) and 1.412 ± 0.0017 (etafilcon A). The change in in vivo RI across the day was statistically significant for the etafilcon A lens (repeated-measures analysis of variance, P<0.01) but not for the lotrafilcon B lens (P>0.05).

Conclusions: This novel adaptation of refractometry was able to measure the RI of soft contact lenses during wear (without lens removal). End of day RI measurements using in vivo and ex vivo refractometry were comparable with each other. Future work is required to determine whether this in vivo method can improve our understanding of the relationships between soft contact lens RI, hydration, on-eye lens performance, and symptomology.

Fitting soft center-near design multifocal lenses

The recent launch of the Air Optix Aqua Multifocal lens (Ciba Vision) means that there are three silicone hydrogel (SiHy) multifocal lenses available. The benefits of SiHy materials have been well documented (Dumbleton, 2006), but until recently they weren't available in multifocal designs. With an aging population, it's likely that a large number of contact lens wearers are approaching presbyopia, which will result in a dramatic increase in demand for multifocal lenses.

The langauge of tourism : perfecting soft skills in a flat world

India is Australia's 11th-biggest inbound tourism market, bringing in 148,200 visitors who spent $867 million last year, but by 2020 officials say that could reach 300,000 visitors spending $2.3 billion.
Delhi and Mumbai have been targeted by Australia because they have an emerging middle class and India's highest concentration of affluent households.
The Minister for Tourism, Martin Ferguson, unveiled an India 2020 strategic plan last month at the annual Australian Tourism Exchange in Perth, the largest travel trade show in the southern hemisphere. "We have put a huge effort into attracting tourists from China recently and the next cab off the rank is India," he said.
The plan means that Tourism Australia's "There's Nothing Like Australia" campaign will be rolled out in Delhi and Mumbai and there will be extensive advertising on TV and digital channels as well as print.

Size invariance of fibrous networks of supramolecular soft materials during formation under critical volume confinement

The rheological properties of a hierarchically structured supramolecular soft material are mainly determined by the structure of its network. Controlling the thermodynamic driving force of physical gels (one type of such materials) during the formation has proven effective in manipulating the network structure due to the nature of nucleation and growth of the fiber network formation in such a supramolecular soft material. Nevertheless, it is shown in this study that such a property can be dramatically influenced when the volume of the system is reduced to below a threshold value. Unlike un-confined systems, the network structure of such a soft material formed under volume confinement contains a constant network size, independent of the experimental conditions, i.e. temperature and solute concentration. This implies that the size of the fiber networks in such a material is invariable and free from the influence of external factors, once the volume is reduced to a threshold. The observations of this work are significant in the control of the formation of fibrous networks in materials of this type.

The soft systems approach to understanding trust in alliances in Australia

Alliances are complex projects with high levels of risk and uncertainty. Despite the pain share and gain share commercial arrangement in alliances, Trust is still an issue between the Alliancing Leadership Team (ALT) and Alliancing Management Team relationship (AMT). Although the concept and components of trust have been discussed by various researchers, the characteristic of trust under different situations has not been tested within the procurement research domain. Based on semi-structured interviews with the members of the ALT and AMT of an alliance project in Australia the underlying trust based relationships between the AMT and ALT were investigated using the Soft Systems Methodology (SSM). Results demonstrate that cognitive, affect, system and cognitive-affect based trust are mediated by common good, needs, sharing, breach temptation and mishap situations. This research demonstrates that the adversarial culture of the Australian construction industry cannot be changed by the implementation of trust principles alone. The culture of suspicion dominating the ideological view of the construction industry requires organizational learning between alliance parties to execute appropriate behaviours, aligned with the alliancing philosophy, to effectively achieve ideal collaboration.

Three arguments against ‘soft innovation’: towards a richer understanding of cultural innovation

This paper critiques recent research on innovation in the cultural and creative industries. In particular, this paper examines Paul Stoneman’s idea of ‘soft innovation’ as a jumping off point for discussing theories of cultural innovation more broadly. Three critiques are advanced. Firstly, soft innovation is a theoretical perspective that has developed from neoclassical economics, and is therefore vulnerable to criticisms levelled at neoclassical explanations of economic behaviour. Secondly, the theory of soft innovation can be criticised for being contin- gently inaccurate: the observed reality of cultural industries and marketplaces may not reflect the theory’s premises. Thirdly, because soft innovation defines the significance of an innovation in terms of marketplace success, it implies that only high-selling cultural products are significant, a difficult claim to substantiate. This paper concludes by arguing that our understanding of innovation in the cultural sphere can benefit from a multi-disciplinary approach grounded in the full gamut of human creativity.
