Backlash as god forced into schools

The Victorian Education Department is forcing public primary schools to run Christian education classes taught by volunteers, angering parents and schools that do not want to host them.

Intergenerational differences in food, physical activity, and body size perceptions among African migrants

We assessed intergenerational differences in food, physical activity, and body size perceptions among refugees and migrants from the Horn of Africa living in Victoria, Australia. We used a qualitative design and obtained data from 48 participants (18 individual interviews; 3 semistructured focus groups). Three major themes emerged: (a) food and physical activity, (b) preference of body size and social expectations, and (c) perceived consequences of various body sizes. For parents, large body size was perceived to equate with being beautiful and wealthy; slimness was associated with chronic illness and poverty. Parents adopted strategies that promoted weight gain in children. These included tailored food practices and restricting children’s involvement in physical activity. For young people, slimness was the ideal body size endorsed by their peers, and they adopted strategies to resist parental pressure to gain weight. Obesity-prevention programs in this subpopulation need to adopt a multigenerational approach.

Aspects of parenting and family functioning associated with obesity in adolescent refugees and migrants from African backgrounds living in Australia

Objective: To investigate the relationship between parenting style and family functioning, and BMI, among adolescent migrants and refugees from African countries.

Method: A total of 104 parents and their adolescent offspring completed questionnaires assessing the variables of interest, and anthropometric data were collected from them.

Results: Parents reported higher maternal involvement, lower levels of paternal involvement, higher levels of positive parenting, greater use of ‘other’ (non-corporal) discipline styles, greater satisfaction and better communication than did their offspring. Parents also reported greater family cohesion and flexibility than adolescents, and saw their families as more enmeshed and more rigid. Parenting style and family functioning were not strong predictors of BMI according to either report. For adolescents, inconsistent discipline and lack of parental supervision accounted for significant variance in BMI.

Conclusions: Inconsistent discipline and lack of parental supervision may be related to adolescent BMI. Further studies with larger samples are required to confirm these relationships with the view to informing obesity prevention programs for this target population.

Implications: Prevention or intervention programs aimed at reducing the prevalence of overweight and obesity need to consider parenting style in their design.

Making Connections in Geelong : migrants, social capital and growing regional cities

Migration has been increasingly used to compensate for demographic trends and skill shortages in developed countries. This has resulted in policies to encourage migration to regional areas in order to relieve pressures on liveability and infrastructure in big cities. Like many other regional cities in Victoria, Geelong actively encourages migrants from overseas, from Melbourne and from other parts of rural and regional Australia, by promoting workforce participation, and enhancing lifestyles to attract and retain a growing population. A number of countries including Australia, Canada, Italy and Spain have policies to encourage immigration to locations other than large urban centres to stimulate regional economic development and to ensure immigrants fill skill shortages in regional areas. However, migrants do not always stay long in the regional locations where they initially settle, and new migrants are needed to replace their skills. Given the Australian and Victorian government policy imperatives of encouraging regional migration there is a need to understand how migrants and their families make the social connections that contribute to wellbeing and their retention in regional areas such as Geelong. This paper emerges from a research project on this challenge at Deakin University, in Geelong It discusses some of the issues associated with regional migration and describes how a sound, theoretically informed understanding of social capital can assist employers, governments and community groups (formal and informal) to effectively assist migrants to make social connections and therefore remain in regional cities.

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.

Lost at sea: genetic, oceanographic and meteorological evidence for storm-forced dispersal

For many species, there is broad-scale dispersal of juvenile stages and/or long-distance migration of individuals and hence the processes that drive these various wide-ranging movements have important life-history consequences. Sea turtles are one of these paradigmatic long-distance travellers, with hatchlings thought to be dispersed by ocean currents and adults often shuttling between distant breeding and foraging grounds. Here, we use multi-disciplinary oceanographic, atmospheric and genetic mixed stock analyses to show that juvenile turtles are encountered ‘downstream’ at sites predicted by currents. However, in some cases, unusual occurrences of juveniles are more readily explained by storm events and we show that juvenile turtles may be displaced thousands of kilometres from their expected dispersal based on prevailing ocean currents. As such, storms may be a route by which unexpected areas are encountered by juveniles which may in turn shape adult migrations. Increased stormy weather predicted under climate change scenarios suggests an increasing role of storms in dispersal of sea turtles and other marine groups with life-stages near the ocean surface.

'Everybody has settled in so well': How migrants make connections and build social capital in Geelong

Australian and Victorian Government policies encourage settlement in regional areas for international migrants, refugees and internal migrants. Migrants to regional areas are diverse in terms of their area or country of origin, skills and occupation, family status and other demographic characteristics. The regional cities to which they migrate are also varied in terms of their community resources, social and cultural capital. The objective shared by all of these cities is for migrants to engage successfully with their new communities. Just how this occurs is the subject of debate and a lack of clarity. This therefore calls for a sound, theoretically informed understanding of how employers and community groups (formal and informal) can effectively assist migrants to make social connections in regional cities, and practical strategies which respond to these insights. The well-established social determinants of health tell us that the more socially included, connected and stable workforce and their families are, the better will be their physical and mental health and wellbeing.

Testing the navigational abilities of ocean migrants: displacement experiments on green sea turtles (Chelonia mydas)

Like many animals migrating through the oceans, sea turtles face difficult navigational tasks when they have to reach distant, specific sites. The paradigmatic case of Brazilian green turtles (Chelonia mydas), which nest on the tiny Ascension Island in the middle of the Atlantic Ocean, has often been the subject of hypotheses concerning their navigational mechanisms. To investigate their nature, we displaced 18 females from Ascension and tracked them by satellite after release from eight different points in the ocean, 60–450 km away from the island. Four turtles moved to Brazil soon after the release, 4 moved in various directions before heading to Brazil, and 10 reached the island. All the successful trips, bar 1, were winding but ended with a final straight segment of variable length, as if the turtles were searching for a sensory contact with the island which they obtained at various distances. The approach to Ascension mostly occurred from the direction opposite to the trade wind, suggesting a navigational role of wind-borne information originating from the island.

Oceanic long-distance navigation : do experienced migrants use the earth's magnetic field?

Albatrosses and sea turtles are known to perform extremely long-distance journeys between disparate feeding areas and breeding sites located on small, isolated, oceanic islands or at specific coastal sites. These oceanic journeys, performed mainly over or through apparently featureless mediums, indicate impressive navigational abilities, and the sensory mechanisms used are still largely unknown. This research used three different approaches to investigate whether bi-coordinate navigation based on magnetic field gradients is likely to explain the navigational performance of wandering albatrosses in the South Atlantic and Indian Oceans and of green turtles breeding on Ascension Island in the South Atlantic Ocean. The possibility that magnetic field parameters can potentially be used in a bi-coordinate magnetic map by wandering albatrosses in their foraging area was investigated by analysing satellite telemetry data published in the literature. The possibilities for using bi-coordinate magnetic navigation varied widely between different areas of the Southern Oceans, indicating that a common mechanism, based on a bi-coordinate geomagnetic map alone, was unlikely for navigation in these areas. In the second approach, satellite telemetry was used to investigate whether Ascension Island green turtles use magnetic information for navigation during migration from their breeding island to foraging areas in Brazilian coastal waters. Disturbing magnets were applied to the heads and carapaces of the turtles, but these appeared to have little effect on their ability to navigate. The only possible effect observed was that some of the turtles with magnets attached were heading for foraging areas slightly south of the control turtles along the Brazilian coast. In the third approach, breeding female green turtles were deliberately displaced in the waters around Ascension Island to investigate which cues these turtles might use to locate and return to the island; the results suggested that cues transported by wind might be involved in the final stages of navigation.
