Students' assessment of their neighbourhood socio-physical environment : difference between Sydney and Beijing

This study compared children's assessments of their neighbourhood environments in Sydney and Beijing.Students from nine high schools in Sydney ( N = 166) and two high schools in Beijing ( N = 234) participated in a survey study. Exploratory factor analysis, AN OVA, and structural equation modeling were used to analyse data. Items in the CNE Scale were clustered into four factors: Route to School, Vegetation & Facilities, Neighbours and Convenience. Significant national difference was found on one factor of neighbourhood environment: Rout to School. Structural equation modeling revealed a significant correlation between the constructs" country" and "neighbourhood socio-physical environment" , implying a relationship between the two. In sum, the findings suggested that children in Sydney were more satisfied with their overall neighbourhood socio-physical environment, especially regarding their routes to school.

The ethical difference of Organization

Noting that from its very inception Organization laid claim to having a central interest in the ethics and politics of organization, in this article we review contributions to the Journal over the past 20 years in order to consider the ethical thinking that has developed. We suggest that there is a common thread of ethical interest that characterizes much of this work—one that clearly differentiates it from more conventional approaches to business ethics. While business ethics has as its locus of interest the ethicality of organizations themselves, central issues that have emerged in Organization concern how individuals might (or might not) maintain a valued experience of themselves as ethical subjects despite the behaviour of organizations, and how organizational arrangements might be politically contested in the name of ethics. We explore this in relation to a question that unites much of the study of ethics in Organization: how do we live (and work) together in a world beset by difference? We consider this question in terms of the issue of ethical subjectivity and the relation between an ethics of consensus and an ethics of difference. The article concludes much as the Journal started—with the proposal that ethics remains a pressing challenge for critical scholarship and practice.

Training skills of divided attention among older adults

The current study examined whether video game training would help improve divided attention skills among older adults. Twenty-nine (4 males, 25 females) participants aged 50 to 84 years (M = 70) were tested for their skills of divided attention using a memory and reaction time task. Participants were randomly allocated to the experimental group and control group and only those in the experimental group trained with the computer game, Pac-Man Adventures in Time for three hours. Results show that three hours of training are not sufficient to enhance skills of divided attention amongst older adults as the differences in these skills were not significantly different between control and experimental groups. These findings suggest that greater amounts or other methods of training may be required to enhance older adults’ ability to perform dual tasks.

Perceived discrimination and stigmatisation against severely obese women : age and weight loss make a difference

Aims: Patients’ perceptions about weight-related stigma and discrimination were assessed in 2 groups of patients, obese and laparoscopic adjustable gastric banding (LAGB).

Methods: Seven focus group sessions were held including a total of 32 women, 8 obese (body mass index 35+) and 24 who had lost 50% of excess weight following bariatric surgery. During the sessions, participants were asked to consider their experiences in situations including general, family, friends, work place, medical, and educational settings.

Results: Whilst perceptions of discrimination and stigmatisation were common and affected many life situations, they were less prevalent than previous reports. It appeared that it was not the frequency or number of events which affected an individual but the intensity of the experience. Younger women reported greater discrimination than older women and felt the social consequences of obesity to a greater extent. Older women were more concerned about the consequences of being overweight on their health.

Conclusions: Women who had lost weight considered that aspects of their own behaviours when obese contributed to their experiences of discrimination and stigmatisation. Perceptions of discrimination and stigmatisation appear to be influenced by age and current weight status.

The effects of apoptosis vulnerability markers on the myocardium in depression after myocardial infarction

Background : There is an increased incidence of major depressive disorder (MDD) in individuals after myocardial infarction (MI), but the pathophysiological processes mediating this association are unclear. Our previous study demonstrated an increase in pro-apoptotic pathways in the myocardium and hippocampus in MDD, which was reversed by venlafaxine. This study aimed to attempt to confirm the effects of apoptosis vulnerability markers on the myocardium in a model of depression after myocardial infarction.

Methods : Rats were divided into four groups: sham (N = 8), depression (N = 8, chronic mild unpredictable stress and separation were used in the depression group), MI (N = 13) and post-MI depression (N = 7). The rats in all four groups underwent the same open field and sucrose preference behavioral tests. Evan Blue staining was used to determine the area at risk of myocardial infarction in the left ventricle, and 2,3,5-triphenyl tetrazolium chloride (1.5% TTC) dye was used to detect the size of the myocardial infarction. The expression of bax and bcl-2 protein in the myocardium was investigated by immunohistochemistry, and the mRNA expression of bax, bcl-2 and caspase-3 in the myocardium was investigated by real time RT-PCR. Apoptosis was estimated in the myocardium by measuring the Bax:Bcl-2 ratio.

Results : In the depression and post-MI depression rats, there were significantly decreased movements and total sucrose consumption, modeling behavioral deficits and an anhedonic-like state. In terms of myocardial infarction size, no difference was seen between the MI and post-MI depression groups. There was an up-regulated Bax:Bcl-2 ratio in the depression, MI and post-MI depression groups. Furthermore, in the latter group, there was a greater up-regulated Bax:Bcl-2 ratio. However, caspase-3 did not differ among the four groups.

Conclusions : These results of this animal model suggest that active pro-apoptotic pathways may be involved in the nexus between myocardial infarction and depression. This mechanism may be germane to understanding this relationship in humans.

Making a difference for young gifted and talented children

Online resource, Department of Education and Early Childhood Development

Professionals who work with young children who are gifted or talented can make a real difference to them reaching their full potential.

This resource provides early childhood professionals with information and resources to help identify and provide learning for young gifted and talented children (from infancy to eight years old) and their families.

Gifted and talented young children experience wellbeing and positive development when provided with supportive and challenging learning environments that are responsive to their individual strengths and interests.

Every early childhood professional will be working with gifted children. It is estimated that 10–15 per cent of children are gifted, which means a typical early childhood group or school class will contain at least one gifted child. Many will have more, so it is imperative that professionals reflect on their practice and seek professional learning opportunities to increase their understanding and knowledge of giftedness and talent in young children.

Research has shown that educators who have received professional learning opportunities or pre-service preparation in giftedness and talent are better able to recognise and understand giftedness in children, and have more positive attitudes towards it.

The professional learning opportunities in this online resource will assist professionals to identify and engage in good practice when working with young gifted and talented children.

In/exclusion: the politics of difference

The inclusion debate has raised issues in relation to ascertainment, the labelling of 'special' needs, the distribution of human and physical resources and the placement of students on individualized education programmes. This paper contends that the inclusion debate, however, has not addressed critical issues pertaining to the politics of representation and difference. That is, the normative struggles over rights and social justice for the disabled have largely elided differing cultural constructions of disability and the question of who speaks for and represents whom.

A little movement orientated to the geomagnetic field makes a big difference in strong flows

Whilst a range of animals have been shown to respond behaviourally to components of the Earth’s magnetic field, evidence of the value of this sensory perception for small animals advected by strong flows (wind/ocean currents) is equivocal. We added geomagnetic directional swimming behaviour for North Atlantic loggerhead turtle hatchlings (Caretta caretta) into a high-resolution (1/4°) global general circulation ocean model to simulate 2,925-year-long hatchling trajectories comprising 355,875 locations. A little directional swimming (1–3 h per day) had a major impact on trajectories; simulated hatchlings travelled further south into warmer water. As a result, thermal elevation of hatchling metabolic rates was estimated to be between 63.3 and 114.5% after 220 days. We show that even small animals in strong flows can benefit from geomagnetic orientation and thus the potential implications of directional swimming for other taxa may be broad.

Beyond eurocentrism? Heritage conservation and the politics of difference

There is a long-standing debate concerning the suitability of European or ‘western’ approaches to the conservation of cultural heritage in other parts of world. The Cultural Charter for Africa (1976), The Burra Charter (1979) and Nara Document on Authenticity (1994) are notable manifestations of such concerns. These debates are particularly vibrant in Asia today. This article highlights a number of charters, declarations and publications that have been conceived to recalibrate the international field of heritage governance in ways that address the perceived inadequacies of documents underpinning today’s global conservation movement, such as the 1964 Venice Charter. But as Venice has come to stand as a metonym for a ‘western’ conservation approach, intriguing questions arise concerning what is driving these assertions of geographic, national or civilisational difference in Asia. To address such questions, the article moves between a number of explanatory frameworks. It argues declarations about Asia’s culture, its landscapes, and its inherited pasts are, in fact, the combined manifestations of post-colonial subjectivities, a desire for prestige on the global stage of cultural heritage governance and the practical challenges of actually doing conservation in the region.
