Physical activity and determinants of physical activity in obese and non-obese children

OBJECTIVE To compare the physical activity (PA) patterns and the hypothesized psychosocial and environmental determinants of PA in an ethnically diverse sample of obese and non-obese middle school children. DESIGN Cross-sectional study. SUBJECTS One-hundred and thirty-three non-obese and 54 obese sixth grade children (mean age of 11.4 +/-0.6). Obesity status determined using the age-, race- and gender-specific 95th percentile for BMI from NHANES-1. MEASUREMENTS Objective measurements were collected of PA over a 7-day period using the CSA 7164 accelerometer: total daily counts; daily moderate (3-5.9 METs) physical activity (MPA); daily vigorous physical activity (greater than or equal to 6 METs; VPA); and weekly number of 5, 10 and 20 min bouts of moderate-to-vigorous physical activity (greater than or equal to 3 METs, MVPA). Self-report measures were collected of PA self-efficacy; social influences regarding PA, beliefs about PA outcomes; perceived PA levels of parents and peers, access to sporting and/or fitness equipment at home, involvement in community-based PA organizations; participation in community sports teams; and hours spent watching television or playing video games. RESULTS Compared to their non-obese counterparts, obese children exhibited significantly lower daily accumulations of total counts, MPA and VPA as well as significantly fewer 5, 10 and 20 min bouts of MVPA. Obese children reported significantly lower levels of PA self-efficacy, were involved in significantly fewer community organizations promoting PA and were significantly less likely to report their father or male guardian as physically active. CONCLUSIONS The results are consistent with the hypothesis that physical inactivity is an important contributing factor in the maintenance of childhood obesity. Interventions to promote PA in obese children should endeavor to boost self-efficacy perceptions regarding exercise, increase awareness of, and access to, community PA outlets, and increase parental modeling of PA.

Effects of perspective taking and entitlement on consumers

Perspective taking involves mentally putting yourself in another's shoes and has been shown to offer interpersonal benefits, however, despite its use in campaigns targeting adolescents, it has been relatively neglected in marketing. This paper examines the moderating effect of entitlement in young adolescent consumers, focusing on perspective taking encouraging a prosocial behavior. This research extends existing marketing literature which to date has examined perspective taking in relation to adult behavior (Davis et al., 2004; Galinsky et al., 2008; Dietvorst et al., 2009), contributing to the study and understanding of adolescent consumers' consumer behavior. Three experiments were conducted which demonstrate that perspective taking benefits occur for nonentitled adolescents but not for entitled adolescents. Effects for perspective taking and entitlement are driven by evaluative concern for nonentitled adolescents and a perceived lack of relational closeness for entitled adolescents.

Parent's socio-economic status and social support as risks for child mortality : consideration of health equity in The Gambia

A matched case-control study of mortality to children under age five was conducted to consider associations with parents' socio-economic status and social support in the Farafenni Demographic Surveillance Site (DSS). Cases and controls were selected from Farafenni DSS, matched on date of birth, and parents were interviewed about personal resources and social networks. Parents with the lowest personal socio-economic status and social support were identified. Multivariate multinomial regression was used to consider whether the children of these parents were at increased risk of either infant or 1-4 mortality, in separate models using either parents' characteristics. There was no benefit found for higher SES or better social support with respect to child mortality. Children of fathers who had the poorest social support had lower 1-4 mortality risk (OR=0.52, p=0.037). Given that socio-economic status was not associated with child mortality, it seems unlikely that the explanation for the link between father's social support and mortality is linked to resource availability. Explanations for the risk effect of father's social ties may lie in decision-making around health maintenance and health care for children.

Total factor productivity growth and convergence in the petroleum industry : empirical analysis testing for convexity

While economic theory acknowledges that some features of technology (e.g., indivisibilities, economies of scale and specialization) can fundamentally violate the traditional convexity assumption, almost all empirical studies accept the convexity property on faith. In this contribution, we apply two alternative flexible production technologies to measure total factor productivity growth and test the significance of the convexity axiom using a nonparametric test of closeness between unknown distributions. Based on unique field level data on the petroleum industry, the empirical results reveal significant differences, indicating that this production technology is most likely non-convex. Furthermore, we also show the impact of convexity on answers to traditional convergence questions in the productivity growth literature.

The Ash Burner

Growing up with his father in a small coastal town, all Ted knows about his mother is that she died when he was a boy. His father has brought them halfway across the world to start anew, but her absence defines and haunts their lives. When Ted meets Anthony and Claire, an intense friendship begins, carrying them to Sydney and university. They introduce him to poetry and art, and he feels a sense of belonging at last. But as the trio’s friendship deepens over the years, Ted must learn to negotiate the boundaries of love, and come to terms with a legacy of secrets and silence. Written with extraordinary grace and sensitivity, The Ash Burner explores beauty and desire, grief and loss, and the search for one’s true self.

Flood victim’s heartbreak : ‘don’t be complacent about the risk’

"No one had higher stakes in the findings of the Queensland Floods Commission of Inquiry than Grantham father Matthew Keep, whose mother, mother-in-law and baby daughter, Jessica, died at Grantham that terrible day in January. For seven months he has read every statement, submission, running log, disaster management plan and media article available. As he has comforted his grieving wife, Stacy, helped care for his two young children Madison, 5, and Jacob, 4, who amazingly survived the flood, and welcomed a new baby into the family, Matthew has searched for answers for himself and his community. Why were authorities not able to warn people in seven towns in Toowoomba and the Lockyer Valley that the worst flash flooding in at least a century was about to strike, killing 22 people? How could such a sudden and catastrophic flood claim three members of his family within minutes?"

Commercial friendships between gay salesmen and straight female customers

Perhaps it is now sacrosanct in marketing to contemplate that many service encounters, especially those in retail settings, are social encounters in which bonds between and among customers and employees are critical drivers of consumption (Beatty et al., 1996; Rosenbaum, 2006). Indeed, within retail settings, it is often possible for salespeople and customers to form so-called “commercial friendships” (Price and Arnould, 1999). These friendships result in both salespeople and their customers having social interactions that are close to those experienced in personal friendships (Swan et al., 2001), and which are extremely satisfying for all parties. Outside of marketing, the social science literature (Grigoriou, 2004; Rumens, 2008; Russell, DelPriore, Butterfield, and Hill, 2013) and popular press (de la Cruz and Dolby, 2007; Hopcke and Rafaty, 1999; Tilmann-Healy, 2001, Whitney, 1990) is replete with knowledge regarding the “absolutely fabulous” friendships (Hopcke and Rafaty, 1999) that often form between gay men and straight women. In fact, Western culture regularly highlights the compatibility of gay men and straight women in film, television, and writing, to the extent that they have now influenced popular thinking on the topic, so that gay men and straight females are viewed as sharing common plights and interests (Rumens, 2008). Yet, thus far, marketing researchers have looked askance at the effect of friendships between gay male employees and heterosexual female customers in consumption settings, such as retail stores and boutiques. Indeed, with the exception of Peretz’s (1995) participant observation regarding how young and outwardly gay salesmen use their ambiguous gender to sell women’s clothing, in a Paris-based luxury boutique, any theoretical explorations regarding retail-based commercial friendships between gay salesmen and female customers are non-existent—until now. This research addresses this apparent chasm in the literature by putting forth an original framework that shows how the emotional closeness between gay salesmen and female customers, due to the absence of sexual interest and inter-female competition, results in an intense emotional closeness, that facilitates pleasurable retail transactions, customer satisfaction, loyalty, and positive word-of-mouth. In doing so, this work extends the commercial friendship paradigm by considering retail-based, commercial friendships between an under-researched marketplace dyad; gay men and straight females. It is worth noting here that some straight women may find the idea of commercial friendships with gay salesmen as undesirable, due to the very notion of having relationships with retail organizations or employees (Noble and Phillips, 2004), or a personal disdain for homosexuality.

Donald Ezekiel AM : passionate and innovative contact lens practitioner and manufacturer

Donald Ezekiel (known to all as ‘Don’) was born in Singapore on September 12, 1936, to a German mother and Iraqi father. His parents were Jewish refugees, who met in Batavia,1 married and alternately lived in Batavia and Singapore. The family established their primary residence in Singapore after Don’s older brother Eric (later to become a haematologist) was born in 1934. The Ezekiel family was forced to flee in 1941 when the Japanese bombed Singapore and were fortunate to obtain passage on a hospital ship to Perth. They returned to Singapore after the war but left again on their own accord in 1951 due to race riots. The Ezekiels sold up everything in Singapore and decided to settle in Perth...

Paternal postnatal depressive symptoms, infant sleeping and feeding behaviors, and rigid parental regulation : a correlational study

Paternal postnatal depression (PND) is now recognized as a serious and prevalent problem, associated with poorer well-being and functioning of all family members. Aspects of infant temperament, sleeping and feeding perceived by parents as problematic are associated with maternal PND, however, less is known about paternal PND. This study investigated depressive symptoms (Edinburgh postnatal depression scale (EPDS)) in 219 fathers of infants aged from 1 to 24 weeks (median 7.0 weeks). Infant predictor variables were sleeping problems, feeding problems and both mother and father reported temperament. Control variables were partner’s support, other support and life events. Rigidity of parenting beliefs regarding infant regulation was also measured as a potential moderating factor. Infant feeding difficulties were associated with paternal depressive symptoms, subsuming the variance associated with both sleep problems and temperament. This relationship was not moderated by regulation beliefs. It was concluded that infant feeding is important to fathers. Fathers of infants with feeding difficulties may not be able to fulfill their idealized construction of involved fatherhood. Role incongruence may have an etiological role in paternal PND.

Videogames: Dispelling myths and tabloid headlines that videogames are bad

Videogamers are often portrayed as adolescent overweight males eating fast food in their bedroom, and videogames often blamed in the media for violent crime, obesity, social isolation and depression. However videogaming is a mainstream activity. In Australia 65% of the population play videogames (Digital Australia 2014), and humanity as a species play about 3 billion hours of videogames a week. This paper dispels the myths and sensationalised negative tabloid headlines that videogames are bad by presenting the latest research showing that videogames can help fight depression, improve brain function and stimulate creativity; that gamers have higher levels of family closeness and better attachment to school; and that videogames help boys and young men to relax, cope and socialise. Children and adolescents deliberately choose to play videogames in the knowledge that they will feel better as a result, and videogame play allow players to express themselves in ways they may not feel comfortable doing in real life because of their appearance, gender, sexuality, and/or age. The potential benefits of videogames to the individual and to society are yet to be fully realised. However already videogames are helping many gamers to flourish in life.

Polybrominated diphenyl ethers and age: analysis of pooled human blood serum from birth to over 60 years

Polybrominated diphenyl ethers (PBDEs) are considered to be a cost effective and efficient way to reduce flammability therefore reducing harm caused by fires. PBDEs are incorporated into a variety of manufactured products and are found worldwide in biological and environmental samples (e.g. Hites et al. 2004). Unlike other persistent organic pollutants there is limited data on PBDE concentrations by age and/or other population specific factors. Some studies have shown no variation in adult serum PBDE concentrations with age (e.g. Mazdai et al., 2003, Meironyte Guvenius et al., 2003) while Petreas et al. (2003) and Schecter et al. (2005) found results to be suggestive of an age trend in adult data but no statistically significant correlation was found. In addition to the data on adult concentrations there is limited data which investigates the levels of PBDEs in infants and young children. Fangström et al. (2005) showed that in seven year olds there was no difference in PBDE concentration when compared to adult concentrations. While Thomsen et al. (2002, 2005) found the concentration of PBDEs in pooled samples of blood serum from a 0-4 years age group to be higher than other age groups (4 to > 60 years). In addition, a family of four was studied in the U.S. and the concentrations were found to be greatest in the 18-month-old infant followed by the 5 year old child, then the mother and father (Fischer et al., 2006). The objectives of this study were to assess age, gender and regional trends of PBDE concentrations in a representative sample of the Australian population.

Representing places never visited: Landscape and the diasporic imagination

While landscape photography’s complicity with the colonial possession of new territory has been substantially discussed and well understood, this paper considers the role of the European landscape as the focus of diasporic desire. The interdisciplinary project, S2Q/Good Blood began as a social history map of Scandinavian and Nordic migration to Queensland in the nineteenth century, incorporating archival material from local collections with visual field trip data gathered in Denmark, Sweden, Norway and Finland. In 2011, some of this material found its way into the installation work, 'my mother is water, my father is wood'. What emerged from this experiment was an imaginary landscape, melding its loci through original photography and video footage in tandem with stock imagery and historical material. This juxtaposition reinforced the represented landscape as a narrative landscape and evidence of the performativity of belonging. This practitioner reflection utilizes Lynette Russell’s research into landscape archaeology to consider the significance of relationships with landscapes that are “not always empirically demonstrable.”

Daubism: Copyright law and artistic works

An artistic controversy over a group of landscape painters called the Daubists provided impetus for copyright law reform in Australia in the early 1990's. In the first exhibition of Daubism in 1991 driller Jet Armstrong painted a crop circle over a painting of the Olgas by Charles Bannon - an artist, print-maker, and the father of the State Premier at the time, John Bannon. He called the resulting work, Crop Circles on a Bannon Landscape. Armstrong also inserted an inverted crucifix over a painting of the Flinders Ranges by Bannon, and renamed the work The Crop Circle Conspiracy Landscape. In response, Bannon took legal action against Armstrong in the Federal Court of Australia on the grounds of false attribution and defamation. He won an interlocutory injunction against Armstrong and the gallery, but then reached a settlement with the Daubists. An anonymous buyer purchased the work for $650 on the condition that it was returned to the painter. In his fight against the Daubists, Bannon received help and support from the National Association for the Visual Arts (NAVA). This professional group used the controversy to campaign for the reform of copyright law - in particular, the need for a moral rights regime. The artistic controversy over the Daubists was a catalyst for the introduction of the Copyright Amendment (Moral Rights) Act 2000 (Cth) in Australia. It offers an illuminating case study of the operation of copyright law in the visual arts.

Team building activities in dance and discoveries from reflective essays

The purpose of this study was to determine if using team building activities within a university Latin dance course enhances cohesion. Students (N=30) completed the Group Environment Questionnaire (GEQ; Carron, Widmeyer, & Brawley, 1985), which measures group integration (individuals’ perceptions of the closeness, similarity, and bonding within the group as a whole) and individual attractions to the group in terms of both task and social cohesion. Students also completed an evaluation of the team building activities and wrote reflective essays about their experiences in the course. The course consisted of twenty 90-minute classes. In the third class students were provided an information sheet describing the research. In the fourth class the students completed a demographics questionnaire and the GEQ. The students completed the GEQ again during the ninth class. In classes 10 to 14 team building activities took up roughly the first third of each class. The students completed the GEQ again in classes 15 and 20. In class 16 the students completed the evaluation. The reflective essays were submitted two weeks after the last class. There were no significant differences across time in social cohesion. Group integration task, however, was significantly higher at times 3 and 4 compared to time 1. Students agreed that the team-building activities helped to bond class members, and felt it was valuable for these activities to be included in the unit in the future. The reflective essays indicated the students felt the team building activities improved social factors, and interpersonal, dance, and personal mental skills.

Commercial friendships between gay sales associates and straight female customers in luxury settings: A proposed theoretical framework

This study investigates friendships between gay sales associates and heterosexual female customers in luxury retail settings. By employing grounded theory methodology, the study integrates theories and findings from diverse literature streams into an original conceptual framework to illustrate the resources gay sales associates and straight female customers receive from and provide to each other during retail exchanges. The study explains why gay male–straight female friendships are uniquely suited for luxury consumption settings. Female customers characterize their friendships with gay sales associates as providing honesty, security, trust, and comfort, which stems from the absence of sexual interest and a lack of inter-female competition. Gay sales associates receive acceptance for who they are and for their displays of unconventional masculinity in retail settings. They also obtain a temporary rite from their female customers, a so-called mandate of privacy, which permits both parties to ignore the bounds of modesty and accept a degree of intimacy. Such intimacy facilitates transactions that require both personalization and customer–employee closeness, such as the selling of high-end apparel, accessories, and jewelry.
