Perceived neighborhood environment and park use as mediators of the effect of area socio-economic status on walking behaviors

Background: Access to local parks can affect walking levels. Neighborhood environment and park use may influence relationships between neighborhood socioeconomic status (SES) and walking.

Methods: Self-report data on perceived park features, neighborhood environment, park use, neighborhood walking and sociodemographics
were obtained from a sample of Australian adults, living in high/low SES areas. Surveys were mailed to 250 randomly selected households within 500m of 12 matched parks. Mediating effects of perceived environment attributes and park use on relationships between area-SES and walking were examined.

Results: Mean frequency of local park use was higher for high-SES residents (4.36 vs 3.16 times/wk, P < .01), who also reported higher levels of park safety, maintenance, attractiveness, opportunities for socialization, and neighborhood crime safety, aesthetics, and traffic safety. Safety and opportunity for socialization were independently positively related to monthly frequency of visits to a local park which, in turn, was positively associated with walking for recreation and total walking. Residents of higher SES areas reported an average 22% (95% CI: 5%, 37%) more weekly minutes of recreational walking than their low SES counterparts.

Conclusion: Residents of high-SES areas live in environments that promote park use, which positively contributes to their weekly amounts of overall and recreational walking.

The attractive female body weight and female body dissatisfaction in 26 countries across 10 world regions : results of the international body project 1

This study reports results from the first International Body Project (IBP-I), which surveyed 7,434 individuals in 10 major world regions about body weight ideals and body dissatisfaction. Participants completed the female Contour Drawing Figure Rating Scale (CDFRS) and self-reported their exposure to Western and local media. Results indicated there were significant cross-regional differences in the ideal female figure and body dissatisfaction, but effect sizes were small across highsocioeconomic-status (SES) sites. Within cultures, heavier bodies were preferred in low-SES sites compared to high-SES sites in Malaysia and South Africa (ds = 1.94-2.49) but not in Austria. Participant age, body mass index (BMI), and Western media exposure predicted body weight ideals. BMI and Western media exposure predicted body dissatisfaction among women. Our results show that body dissatisfaction and desire for thinness is commonplace in high-SES settings across world regions, highlighting the need for international attention to this problem.

Impact of learning environment and learning context on student satisfaction : a comparative study of postgraduate students from Asia

The growth of the international education market with increasing export income has created a highly competitive environment among education providers worldwide. WTO reports that this market is now worth around $27 billion a year (Alderman, 2001) while IDP Australia has estimated an increase in the number of students seeking higher education overseas at 7.2 million by 2025. This alludes to the attractiveness of the international education market in the form of both pecuniary and non pecuniary benefits to provider nations and the higher educational institutions and hence the need for strategies to maintain a globally competitive position. This paper looks at the impact of the learning environment and the learning context on student satisfaction among international postgraduate students from Asia studying in Australian universities. The growing competition requires provider institutions to be highly responsive to the needs and aspirations of the diverse student community and to deliver services to create satisfaction and loyalty, which would be critical in sustaining a competitive position. The study, based on the expectancy-disconfirmation paradigm, and a model of post choice satisfaction in the educational setting, uses logistic regression, MANOVA, ANOVA and chi square testing, investigates factors relevant to student learning environment and the learning context to assess satisfaction levels of these students. The sample size used in the study is 371 and is drawn from a mail survey of five leading universities in Australia.

The integration substitute : the role of controls in managing human asset specificity

As the integration solution to the problem of specific assets cannot be replicated on human asset specificity because slavery is illegal, economic theory states that control systems substitute for integration through a balanced structure to help align diverse interests. To understand the intricate design features of the balance, we examine a case-study firm. For low human asset specificity, the restriction and segregation of usable decision rights link with standards. However, incentives are traced to individuals only to the extent task deviations do not create relevant future costs that are difficult to be self-corrected. For high specificity, incentives are related to outputs rather than outcomes, because outcome variations reduce the attractiveness of maintaining the balance. Subjective assessment is used as an efficient alternate ‘balancing’ solution and decision control is shared when available subjective data are inadequate.

Financial inclusion and financial integrity : aligned incentives?

A large percentage of the population in developing countries saves, remits money or accesses credit using informal financial services. Financial inclusion initiatives aim to expand the reach and attractiveness of formal financial services. Recently, the Financial Action Task Force embraced financial inclusion as complementary to anti-money laundering and counter-terrorist financing as it enhances financial transparency. Analyzing preliminary data from FinScope surveys on eight African countries we argue that an increase in access to formal services does not automatically imply an immediate and corresponding reduction of usage of informal services, especially as many individuals use informal and formal services in parallel. We consider customer trade-offs regarding the use of formal and informal services especially considering transparency as a potential disincentive to use formal services. The alignment of financial inclusion and integrity will fail where customers are apprehensive about increased transparency.

Attack vectors against social networking systems : the Facebook example

Social networking systems (SNS’s) such as Facebook are an ever evolving and developing means of social interaction, which is not only being used to disseminate information to family, friends and colleagues but as a way of meeting and interacting with "strangers" through the advent of a large number of social applications. The attractiveness of such software has meant a dramatic increase in the number of frequent users of SNS’s and the threats which were once common to the Internet have now been magnified, intensified and altered as the potential for criminal behaviour on SNS’s increases. Social networking sites including Facebook contain a vast amount of personal information, that if obtained could be used for other purposes or to carry out other crimes such as identity theft. This paper will focus on the security threats posed to social networking sites and gain an understanding of these risks by using a security approach known as “attack trees”. This will allow for a greater understanding of the complexity associated with protecting Social Networking systems with a particular focus on Facebook.

Weight status associations with physical activity intensity and physical self-perceptions in 10-to 11-year-old children

The study examined associations between children’s weight status, physical activity intensity, and physical self-perceptions. Data were obtained from 409 children (224 girls) aged 10–11 years categorized as normal-weight or overweight/obese. Physical activity was assessed using accelerometry, and children completed the Physical Self-Perception Profile. After controlling for the effects of age, maturation, and socioeconomic status vigorous physical activity was significantly associated with normal-weight status among boys (OR = 1.13, p = .01) and girls (OR = 1.13, p = .03). Normal-weight status was significantly associated with perceived Physical Condition (Boys: OR = 5.05, p = .008; Girls: OR = 2.50, p = .08), and Body Attractiveness (Boys: OR = 4.44, p = .007; Girls: OR = 2.56, p = .02). Weight status of 10–11 year old children was significantly associated with time spent in vigorous physical activity and self-perceptions of Body Attractiveness and Physical Condition.

Sex-dependent selection differentially shapes genetic variation on and off the guppy Y chromosome

Because selection is often sex-dependent, alleles can have positive effects on fitness in one sex and negative effects in the other, resulting in intralocus sexual conflict. Evolutionary theory predicts that intralocus sexual conflict can drive the evolution of sex limitation, sex-linkage, and sex chromosome differentiation. However, evidence that sex-dependent selection results in sex-linkage is limited. Here, we formally partition the contribution of Y-linked and non-Y-linked quantitative genetic variation in coloration, tail, and body size of male guppies (Poecilia reticulata)—traits previously implicated as sexually antagonistic. We show that these traits are strongly genetically correlated, both on and off the Y chromosome, but that these correlations differ in sign and magnitude between both parts of the genome. As predicted, variation in attractiveness was found to be associated with the Y-linked, rather than with the non-Y-linked component of genetic variation in male ornamentation. These findings show how the evolution of Y-linkage may be able to resolve sexual conflict. More generally, they provide unique insight into how sex-specific selection has the potential to differentially shape the genetic architecture of fitness traits across different parts of the genome.

CADET - Centre for Advanced Design in Engineering Training

BACKGROUND : The Centre for Advanced Design in Engineering Training (CADET) is a partnership of Deakin University and the Gordon Institute of TAFE that will improve access and pathways into careers to address Australia’s critical engineering skills shortage (Walton, C). Local high schools, Belmont High and Matthew Flinders Girls Secondary College are included as strategic partners. CADET is proposed to be a teaching and learning facility providing a project focused modern engineering approach to students at regional schools and TAFE as well as Deakin’s degree programs. CADET will emphasize engineering design and development through virtual and physical modelling, simulation and prototyping – skills at the heart of the 21st century engineering challenges, and will serve as an attractor to engineering and related professions.

PURPOSE : The purpose of this paper is to present an argument toward the development of a Centre for advanced design in engineering training. CADET is proposed to increase the awareness and attractiveness of engineering as an education and career option, particularly for women, in regional schools, provide under one roof state-of-the-art engineering design, modelling and prototyping facilities, facilitate access and articulation pathways between school, VET and Higher Education, increase the physical capacity to serve student demand in western Victoria, and reinvigorate engineering as an essential component of a skilled regional economy.

DESIGN/METHOD : The evidenced based argument towards the proposed centre for advanced design in engineering training is based on a detailed literature review as well as a research study with industry representatives in engineering design. The learning principles of the model are also investigated and aligned to the proposed centre.

RESULTS : CADET is a change to the way engineering has traditionally been taught. The outcomes of CADET will be to provide a broad range of contemporary/relevant teaching programs, improve the social benefits gained from teaching programs, improve retention rates, advance partnerships that link with rural and regional victoria, and collaborate with local communities to encourage governments to support regional capacity building. Through focus group interviews and open discussions with industry and academia over the past 12 months on the integration of design skills in engineering education, results indicate that the following key skills are essential elements required for a successful project oriented design based learning curriculum are creative & innovative skills, successful industry engagement, and awareness of design skills in early years. Feedback also showed that 80% of the industry representatives are looking to recruit graduates who acquired design-equipped skill and 60% indicated that they want graduates who acquired knowledge through projects.

CONCLUSIONS : CADET projected benefits are significant at the strategic and operational levels. They include access for more women in engineering, facilitates articulation pathways between VET and HE, targeted recognised critical current engineering skills shortage in Australia, improvement of regional access, attractiveness and participation in tertiary education, achievement of a significant improvement in the teaching-research nexus.

Male great bowerbirds create forced perspective illusions with consistently different individual quality

Males often produce elaborate displays that increase their attractiveness to females, and some species extend their displays to include structures or objects that are not part of their body. Such "extended phenotypes" may communicate information that cannot be transmitted by bodily signals or may provide a more reliable signal than bodily signals. However, it is unclear whether these signals are individually distinct and whether they are consistent over long periods of time. Male bowerbirds construct and decorate bowers that function in mate choice. Bower display courts constructed by male great bowerbirds (Ptilonorhynchus nuchalis) induce a visual illusion known as forced perspective for the female viewing the male's display over the court, and the quality of illusion is associated with mating success. We improved the quality of the forced perspective to determine whether males maintained it at the new higher level, decreased the perspective quality back to its original value, or allowed it to decay at random over time. We found that the original perspective quality was actively recovered to individual original values within 3 d.We measured forced perspective over the course of one breeding season and compared the forced perspective of individual males between two successive breeding seasons. We found that differences in the quality of visual illusion among males were consistent within and between two breeding seasons. This suggests that forced perspective is actively and strongly maintained at a different level by each individual male.

Security in uncertain times: policies for increasing the popularity of life annuities among retirees

Life annuities offer retirees an assured income stream for as long as they live. This makes it surprising that they are unpopular in most markets where their purchase is not compelled by government policy. With the numbers of retirees in the population set to increase dramatically, this low take-up rate of life annuities could exacerbate financial insecurity. Consequently, it is in society’s interest to implement non-coercive policies that increase annuitization levels. Although there is research that has focused on the possible causes of low annuitization rates, much of this research falls short of suggesting comprehensive strategies for persuading retirees to annuitize their savings.

The effects of familiarity and group size on mating preferences in the guppy, Poecilia reticulata

In recent years, it has become evident that frequency dependence in the attractiveness of a particular phenotype to mates can contribute to the maintenance of polymorphism. However, these preferences for rare and unfamiliar male phenotypes have only been demonstrated in small, controlled experiments. Here, we tested the preference for unfamiliar mates in groups of six to 96 individuals over 13 days, in the guppy (Poecilia reticulata). We observed individual behaviour in situ to test whether fish discriminate two unfamiliar individuals among many familiar ones. We found that unfamiliar males and females were preferred over the familiar fishes in all groups and that this effect decayed over time. Increasing group sizes and levels of sexual activity did not hamper the preference for unfamiliar mates, providing further support for the role of frequency dependent mate choice in the maintenance of trait polymorphism in natural populations.

Artificial ornaments manipulate intrinsic male quality in wild-caught zebra finches (Taeniopygia guttata)

The addition of red and green color bands is a commonly used method for manipulating male attractiveness in the zebra finch (Taeniopygia guttata), providing insight into the study of maternal investment and sexual selection. The addition of artificial ornaments has been assumed to manipulate a females’ perception of the male, rather than affecting intrinsic qualities of the male himself. Here, however, we reveal that the artificial band color worn by a male changes his body mass, condition, and courtship display rate. Males wearing red color bands in aviaries prior to mate-choice trials had a significantly higher song rate during trials than those wearing green color bands, alongside a significant increase in mass change and condition. Male song rate was found to significantly correlate with female preference alongside a female preference for red-banded males. However, male song rate in turn increased when female response was positive, suggesting a social feedback between the interacting birds. Our data suggest the presence of socially mediated feedback mechanisms whereby the artificial increase in attractiveness or dominance of a male directly affects other aspects of his attractiveness. Therefore, housing birds in social groups while manipulating attractiveness can directly influence other male qualities and should be accounted for by future studies.
