Parental awareness and attitudes about food advertising to children on Australian television

Objective: To assess parents' concern regarding television food advertising to children and the marketing methods used, their awareness of existing regulations and support for strengthening restrictions, and to determine whether these factors differ across sociodemographic groups.

Methods: A randomly selected sample of 400 parents of children under 14 years in all Australian States and Territories completed the cross-sectional telephone survey in March 2007. Data were weighted by metropolitan and regional population proportions.

Results: Parents were concerned about unhealthy food advertising to children (67.3%), use of popular personalities (67.7%), toys (76.4%), and advertising volume (79.7%). Older parents, of high socioeconomic status (SES), with fewer household televisions were more likely to be concerned. Only 47.4% of parents were aware of current regulations and those with a tertiary education were more likely to be aware: odds ratio (OR) 2.96 (95% CI: 1.55-5.65). Parents supported a change from self-regulation (92.8%), a ban on unhealthy food advertising to children (86.8%) and, to a lesser extent, a ban on all food advertising (37.3%).

Conclusions and implications: There was widespread parental concern about food advertising and strong support for tighter restrictions. Given that the existing regulations rely on complaints and awareness is low, particularly among parents with lower education levels, a system of external monitoring and enforcement is essential. Clearly more effective regulations are needed to protect children and parental support for this is high.

Do food regulatory systems protect public health?

The purpose of this commentary is to consider the extent to which food regulatory systems protect public health, and how a better job could be done. There are fundamental questions about the role of food regulations in responding to changes in food systems and to food-related public health issues. What is meant by the objective ‘to protect public health and safety’ in the context of food regulation? Are current systems well balanced between promoting trade and protecting health? What is the role of nutrition in food regulation? Should food regulation be used to promote as well as to protect public health? Should laws and regulations be used to intervene in the formulation and marketing of foods, or should ‘the market’ merely provide more choices and information for shoppers and consumers to select healthy diets?

Origins of inflated responsibility in obsessive compulsive disorder

The pivotal role of inflated responsibility beliefs in the maintenance and treatment of obsessive-compulsive disorder (OCD) has been clearly demonstrated (Rachman, 1993; Salkovskis, 1998; Shafran, 1997; van Oppen & Arntz, 1994). Yet little is known about the origins of these beliefs, their contribution to a sense of inflated responsibility or the symptoms of OCD, or the contribution of personality to inflated responsibility and to OCD, The aims of this thesis were to investigate a model of the inter-relationships among the personality dimensions of neuroticism and psychoticism, inflated responsibility and OCD, and the origins of inflated responsibility to inflated responsibility and to OCD. In order to achieve these aims, a scale was developed to assess the origins of inflated responsibility based upon the five pathways proposed by Salkovskis, Shafran, Rachman, and Freeston (1999) and the additional domains of guilt, vigilance and thought-action fusion (Shafran, Thordarson, & Rachman, 1996; Shafran, Watkins & Charman, 1996; Tallis, 1994). Eighty-four participants with OCD (age M = 43.36) and 74 control participants (age M =37.14) volunteered to participate in the two studies of this thesis. The aim of Study 1 was to develop and validate a measure of the Origins of Inflated Responsibility (OIR). The results of the first study yielded a 25-ttem scale, the Origins of Inflated Responsibility Questionnaire (OIRQ) with five independent factors: responsibility, strictness, protection from responsibility, critical incidents, and peer blame which demonstrated both internal reliability and temporal stability over a 2-week period. In Study 2, participants also completed the Responsibility Attitudes Scale (Salkovskis, Wroe, Gledhill, Morrison, Forrester, Richards, ct al. (2000) (a measure of inflated responsibility), the Padua Inventory (Sanavio, 1988) (to measure of the symptoms of OCD)y and the Eysenck Personality Inventory-Revised (Eysenck & Eysenck, 1991). Multivariatc Analysis of Variance revealed that the OCD group scored higher on all variables than the control group except for strictness where the groups were not different, and psychoticism where the OCD group scored lower. A series of Multiple Regression analyses revealed that both group and the OIR contributed to inflated responsibility (R2 = .56). When all variables, OIR, inflated responsibility and neuroticism were entered as predictors of OCD, 60% of the variance in OCD was explained however, 49% of the variance was shared by the independent variables suggesting the presence of some underlying construct. Structural Equation Modelling, where all the constructs in the model were examined simultaneously, revealed that neuroticism contributed to the OIR, inflated responsibility and OCD. The OIR were also significant predictors of inflated responsibility and indirectly through inflated responsibility predictive of OCD. The OIR also directly predicted OCD and when the total effects are considered, their contribution was greater than the total effect for inflated responsibility alone. The results of these studies provide good support for the origins of inflated responsibility proposed by Salkovskis et al. (1999), as measured by the OIRQ developed for use in the current thesis. The results also support the contribution of inflated responsibility and neuroticism, as well as the OIR, to OCD, The large amount of variance shared by the OIR, inflated responsibility and neuroticism suggest that there might be some underlying construct, perhaps of a biopsychosocial nature, that requires further investigation for its role in the onset and maintenance of OCD. The clinical relevance of these findings is discussed in terms of early prevention strategies and interventions.

Board behaviour and the global financial crisis : time for a holistic approach to governance

The heightened focus on corporate governance in the aftermath of the financial crisis and in particular the failure of boards to protect their corporations indicates the timeliness of this paper. Although corporate governance has been traditionally linked to control and compliance, the complexities of the 21st Century have focused attention on the need for more holistic approaches. This paper picks up these developments and using interpretive research, analyses thirteen in-depth interviews conducted with board members and senior management, before and after the crisis. The longitudinal data provides valuable insight into the role of boards, their behaviour, culture and decision-making structures.

Survivin : a target from brain cancer to neurodegenerative disease

Apoptosis is an important contributing factor during neuronal death in a variety of neurodegenerative disorders, including multiple sclerosis, Parkinson's disease and sciatic nerve injury. Whereas several clinical and preclinical studies have focused on the neuroprotective effects of caspase inhibitors, their clinical benefits are still unclear. Here, we discuss novel alternative strategies to protect neuronal cells from apoptotic death using members of the inhibitors of apoptosis (IAP) family. We specifically review the different roles of survivin, which is an important member of the IAP family that serves a dual role in the inhibition of apoptosis as well as a vital role in mitosis and cell division. Due to the various roles of survivin during cell division and apoptosis, targeting this protein illustrates a new therapeutic window for the treatment of neurodegenerative diseases.

The relationship between social capital and depression during the transition to adulthood

Relatively high levels of depression are observed during the transition to adulthood. Hence, it is important to identify the factors that can reduce the incidence of depression at this time. Social capital is theorised to protect against depression by providing greater access to support and psychological resources. Social capital incorporates both interpersonal relationships and broader community-level factors. However, most research has focused on the influence of relationships with parents and peers in the development of depression in young people, with little attention given to the role of broader social capital factors relating to perceptions of and engagement with the wider community. Drawing on longitudinal data from the Australian Temperament Project (ATP), this article examines the effects of close interpersonal relationships (with parents and peers) and broader, community-level aspects of social capital (trust and civic engagement) on depression during the transition to adulthood. Using hierarchical multiple regression, alienation from peers was found to predict higher depression, whereas good communication with peers was associated with a reduction of depressive symptoms. After controlling for the effects of close interpersonal relationships, trust in authorities and organisations made a significant contribution to the prediction of lower depression. Implications for intervention are discussed.

Investigational agents that protect pancreatic islet β-cells from failure

Type 2 diabetes is associated with insulin resistance and reduced insulin secretion, which results in hyperglycaemia. This can then lead to diabetic complications such as retinopathy, neuropathy, nephropathy and cardiovascular disease. Although insulin resistance may be present earlier in the progression of the disease, it is now generally accepted that it is the deterioration in insulin-secretory function that leads to hyperglycaemia. This reduction in insulin secretion in Type 2 diabetes is due to both islet β-cell dysfunction and death. Therefore, interventions that maintain the normal function and protect the pancreatic islet β-cells from death are crucial in the treatment of Type 2 diabetes so that plasma glucose levels may be maintained within the normal range. Recently, a number of compounds have been shown to protect β-cells from failure. This review examines the evidence that the existing therapies for Type 2 diabetes that were developed to lower plasma glucose (metformin) or improve insulin sensitivity (thiazolidinediones) may also have islet-protective function. Newer emerging therapeutic agents that are designed to increase the levels of glucagon-like peptide-1 not only stimulate insulin secretion but also appear to increase islet β-cell mass. Evidence will also be presented that the future of drug therapy designed to prevent β-cell failure should target the formation of advanced glycation end products and alleviate oxidative and endoplasmic reticulum stress.

Book review : Hollywood's copyright wars : from Edison to the internet by Decherney, Peter

A Q methodology study of stakeholders' views about accountability for promoting healthy food environments in England through the responsibility deal food network

In March 2011, the United Kingdom's (UK's) Government launched five Public Health Responsibility Deal Networks to address public health priorities. The Networks used voluntary partnerships to influence peoples' choice architecture to move them toward healthier behaviors. The purpose of this research was to conduct an exploratory study of diverse stakeholders' perspectives about perceived responsibility and accountability expectations to improve food environments in England through the Food Network partnerships. A purposive sample of policy elites (n=31) from government, academia, food industry and non-government organizations sorted 48 statements related to improving food environments in England. Statements were grounded in three theoretical perspectives (i.e., legitimacy, nudge and public health law). PQMethod 2.33 statistical software program used factor analysis to identify viewpoints based on intra-individual differences for how participants sorted statements. The results revealed three distinct viewpoints, which explained 64% of the variance for 31 participants, and emphasized different expectations about responsibility. The food environment protectors (n=17) underscored government responsibility to address unhealthy food environments if voluntary partnerships are ineffective; the partnership pioneers (n=12) recognized government-industry partnerships as legitimate and necessary to address unhealthy food environments; and the commercial market defenders (n=1) emphasized individual responsibility for food choices and rejected government intervention to improve food environments. Consensus issues included: protecting children's right to health; food industry practices that can and should be changed; government working with industry on product reformulation; and building consumer support for economically viable healthy products. Contentious issues were: inadequacy of accountability structures and government inaction to regulate food marketing practices targeting children. We conclude that understanding different viewpoints is a step toward building mutual trust to strengthen accountability structures that may help stakeholders navigate ideologically contentious issues to promote healthy food environments in England.

Metabolic remodelling in obesity and type 2 diabetes: pathological or protective mechanisms in response to nutrient excess?

Altered metabolism in tissues such as the liver, skeletal muscle and adipose tissue is observed in metabolic diseases characterized by nutrient excess and energy imbalance, such as obesity and type 2 diabetes. These alterations in metabolism can include resistance to the hormone insulin, lipid accumulation, mitochondrial dysfunction and transcriptional remodelling of major metabolic pathways. The underlying assumption has been that these same alterations in metabolism are fundamental to the pathogenesis of metabolic diseases. An alternative view is that these alterations in metabolism occur to protect cell and tissue viability in the face of constant positive energy balance. This speculative review presents evidence that many of the metabolic adaptations that occur in metabolic diseases characterized by nutrient excess can be viewed as protective in nature, rather than pathogenic per se for disease progression. Finally, we also briefly discuss the usefulness and potential pitfalls of therapeutic approaches that attempt to correct these same metabolic defects when energy balance is not altered, and the potential links between metabolic survival responses and other chronic diseases such as cancer.

An empirical study on accountability for promoting healthy food environments in England through the public health responsibility deal food network

Objective: In 2011, the United Kingdom launched five Public Health Responsibility Deal Networks inspired by ‘nudge theory’ to facilitate healthy-lifestyle behaviors. This study used Q methodology to examine stakeholders’ views about responsibility and accountability for healthy food environments to reduce obesity and diet-related chronic diseases. Design: A purposive sample of policy elites (n=31) from government, academia, food industry and civil society sorted 48 statements grounded in three theoretical perspectives (i.e., legitimacy, nudge and public health law). Factor analysis identified intra-individual statement sorting differences. Results: A three-factor solution explained 64 percent of the variance across three distinct viewpoints: food environment protectors (n=17) underscored government responsibility to address unhealthy food environments; partnership pioneers (n=12) recognized government-industry partnerships as legitimate; and the commercial market defenders (n=1) emphasized individual responsibility for food choices and rejected any government intervention. Conclusions: Building trust and strengthening accountability structures may help stakeholders navigate differences to engage in constructive actions. This research may inform efforts in other countries where voluntary industry partnerships are pursued to address unhealthy food environments.

Employing sea-level rise scenarios to strategically select sea turtle nesting habitat important for long-term management at a temperate breeding area

Management strategies to protect endangered species primarily focus on safeguarding habitats currently perceived as important (due to high-density use, rarity or contribution to the biological cycle), rather than sites of future ecological importance. This discrepancy is particularly relevant for species inhabiting beaches and coastal areas that may be lost due to sea-level rise over the next 100 years through climate change. Here, we modelled four sea-level rise (SLR) scenarios (0.2, 0.6, 0.9 and 1.3 m) to determine the future vulnerability and viability of nesting habitat (six distinct nesting beaches totalling about 6 km in length) at a key loggerhead sea turtle (Caretta caretta) rookery (Zakynthos, Greece) in the Mediterranean. For each of the six nesting beaches, we identified (1) the area of beach currently used by turtles, (2) the area of the beach anticipated to become inundated under each SLR, (3) the area of beach anticipated to become unsuitable for nesting under each SLR, (4) the potential for habitat loss under the examined SLR, and (5) the extent to which the beaches may shift in relation to natural (i.e. cliffs) and artificial (i.e. beach front development) physical barriers. Even under the most conservative 0.2 m SLR scenario, about 38% (range: 31–48%) total nesting beach area would be lost, while an average 13% (range: 7–17%) current nesting beach area would be lost. About 4 km length of nesting habitat (representing 85% of nesting activity) would be lost under the 0.9 m scenario, because cliffs prevent landward beach migration. In comparison, while the other 2 km of beach (representing 15% nests) is also at high risk, it has the capacity for landward migration, because of an adjoining sand-dune system. Therefore, managers should strengthen actions on this latter area, as a climatically critical safeguard for future sea turtle nesting activity, in parallel to regularly assessing and revising measures on the current high-use nesting habitats of this important Mediterranean loggerhead population.

Attributions of responsibility for motor vehicle accidents and post-injury outcomes.

 This thesis explored the relationship between attributions of responsibility for motor vehicle accidents and post-injury outcomes among a large sample of TAC clients. Results demonstrated that, despite similar levels of physical injury, people who attribute responsibility for accidents to other persons or circumstances experience poorer physical and mental health recovery in comparison to those who attribute responsibility to themselves.
