On global exponential stability of positive neural networks with time-varying delay

This paper presents a new result on the existence, uniqueness and global exponential stability of a positive equilibrium of positiveneural networks in the presence of bounded time-varying delay. Based on some novel comparison techniques, a testable conditionis derived to ensure that all the state trajectories of the system converge exponentially to a unique positive equilibrium. Theeffectiveness of the obtained results is illustrated by a numerical example.

Points of equilibrium: religious beliefs and economic development policy

Eighty per cent of the world's population professes religious belief. Such beliefs provide precepts on how individuals should conduct their private lives and (often) how society should be organized. Given there are 2.1 billion Christians worldwide and 1.3 billion Muslims, understanding the religious approach to social life based on sacred texts and social teachings of Christianity and Islam has a strong relevance to those interested in implementing international economic development policies. This paper argues that religion can thus play a positive role in development and specifically support development economic policies at the international level. The purpose of this paper is not to present a fully formed development economic policy, but rather to identify teachings of the world's two largest religions – such as preferencing the poor, minimizing inequality and having the economy serve wider realms of society – that directly speak to how sustainable economic development is understood within these faith traditions and how these teachings could scaffold and support and international policy frameworks aimed to achieve sustainable economic development.

Optimistic bias for negative and positive events.

Presents results of an investigation into the occurrence of optimistic bias in relation to both positive and negative events, using absolute judgements to assess perceived risk for each of six events. Participants were asked why they offered different ratings for themselves and for others. The results showed that optimistic bias is a pervasive phenomenon that occurs for both positive and negative events. It occurred for all six events when comparisons were made with an unspecified person of the same age and sex, and occurred for three of six events when comparisons were made with the same-sex best friend. Participants could provide information about their own behaviour that they felt justified their positive outlook; however, they implicitly assumed that the comparison target did not engage in the same behaviour. Concludes that risk-reduction education needs to be made personally relevant to the target audience.

"I will start treatment when I think the time is right":HIV-positive gay men talk about their decision not to access antiretroviral therapy.

In a qualitative study, 20 HIV-infected Australian gay men were interviewed about their decision not to access antiretroviral drug therapy. The main reasons given for the decision were fear of side effects; fear of long-term damage to body organs; the inconvenience of the treatment regimens; belief that the regimen's demands would be a threat to morale; and belief that there was no reason to start therapy in the absence of AIDS-related symptoms. Actions taken by the men to monitor and maintain their health included seeing a doctor regularly; having regular T-cell and viral load tests; and trying to maintain a positive outlook by not letting HIV/AIDS 'take over' their lives. Almost half the men considered they had been subjected to unreasonable pressure to access therapy and there was considerable pride at having resisted this pressure. The findings suggest that the men disagreed with the biomedical model for managing HIV/AIDS only on the question of if and when to access therapy. They also suggest that underlying the men's dissent from the biomedical model was a different mode of thinking than is required by the model: while the model demands thinking that is abstract, the men focused strongly on factors close to the 'here and now' of immediate experience. The practical implications of the findings are explored.

Body image, strategies to change muscles and weight, and puberty. Do they impact on positive and negative affect among adolescent boys and girls?

The purpose of this study was to examine the impact of strategies to both decrease weight and increase muscle tone on negative (depression, anxiety) and positive affect among adolescent males and females. The respondents were 1185 adolescents (587 males, 598 females) who were enrolled in grades 7 and 9 (mean age for MALES=13.22 years; mean age for FEMALES=13.21 years). Respondents completed the Body Image and Body Change Inventory that assessed body image satisfaction, body image importance, body change strategies to decrease weight, body change strategies to increase muscle tone, and food supplements. Respondents also completed the Pubertal Development Scale, the depression and anxiety scales of the Depression Anxiety and Stress Scale, and the positive affect items from the Positive and Negative Affect Scale. Structural equation modelling was used to determine how body satisfaction and importance, body change strategies, and puberty impacted on depression, anxiety, and positive affect. The results demonstrated that for both boys and girls, there was a strong association between body change strategies and negative affect. For boys, body dissatisfaction did not predict negative affect, although this was a strong predictor for girls. Body change strategies did not strongly predict positive affect for either boys or girls, although body image satisfaction was a strong predictor for both genders. The implications of these findings for obtaining a better understanding of the role of pubertal development, body image, and body change strategies in predicting positive and negative affect among adolescent males and females are discussed.

Maintaining life satisfaction: the role of positive cognitive bias

Recent research into population standards of life satisfaction has revealed a remarkable level of uniformity, with the mean values for Western populations clustering at around three-quarters of the measurement scale maximum. While this seems to suggest the presence of a homeostatic mechanism for life satisfaction, the character of such a hypothetical device is uncertain. This paper proposes that well-being homeostasis is controlled by positive cognitive biases pertaining to the self. Most particular in this regard are the positive biases in relation to self-esteem, control and optimism. Past controversies in relation to this proposition are reviewed and resolved in favour of the proposed mechanism. The empirical data to support this hypothesis are discussed in the context of perceived well-being as an adaptive human attribute.

The minimum moral content of law : a critique of Hart's descriptive theory of positive and natural law

Review of H.L.A. Hart's account of the minimum moral content of law - assesses its consistency with the methodology provided in his description of the focal meaning or central case of law - particular focus is Hart's consideration of the ultimate end of man - how difficulties faced by Hart's account of the minimum moral content of law can be overcome.

Positive psychology and the demise of defamation

Defamation is one of the more complex and fluid areas of the law and varies considerably across the Australian jurisdictions. There are moves to unify defamation law. The threshold issue that is raised in any such process is whether there is in fact a justification for continuation of defamation law. Recent advances in happiness studies and positive psychology suggest that the chief interest protected by defamation law, reputation, is over-rated and is not in fact conducive to human well-being. What others think of us is not relevant to our well-being. Anecdotally it seems that people spend much time and energy in a bid to impress others in the hope that they will grow in the estimation of others and the world at large. Hence, the results of the studies into human well-being so far as reputation is concerned may appear counter-intuitive. Nevertheless, the studies are far more convincing than lay assumptions. People are often wrong about what is in their interests. This is recognised in the concept of regret. Individuals yearn for some things, but sometimes when they acquire them they discover that the journey was wasted. Reputation is one such thing. Defamation law perpetuates the myth that reputation is intrinsically important. Defamation should be abolished. In its place, a new cause of action should be introduced whereby damages are awardable for misleading and deceptive communications which cause damage to the individual who is the subject of the communication. This cause of action should be modelled on the misleading and deceptive conduct provisions of the Trade Practices Act 1974 (Cth).

Season-ticket holder satisfaction and sponsor-related behaviour: evidence of a positive relationship

Fan attention and response to sponsorship is affected by a range of variables, including the duration of sponsorship and fan commitment to the sporting organisation. The results of surveys of the members of six Australian Football League clubs indicated that there is a positive relationship between the satisfaction levels of season-ticket holders and their orientation towards club sponsors' products and brands.

Sodium adsorption using activated alumina for application in the dairy industry

Basic activated alumina with negatively charged surface is considered as a potential adsorbent for a targeted molecule with positive polarity. Adsorption of sodium by basic activated alumina was investigated as a method for desalting dairy waste streams, in which sodium ion concentration averaged 600 mg/L. Sodium equilibrium and kinetic adsorption were investigated using basic activated alumina with synthetic brines. The results of equilibrium adsorption show that uptake of sodium by activated alumina is significantly higher when the pH is greater than 8 and increases as the pH of the brines increases until pH reaches around 10. The results of kinetic adsorption show that 90 hours were needed to reach equilibrium for sodium adsorption. Binding and diffusion processes are suggested to have taken place within the activated alumina.

Transferring goodwill : are positive attitudes towards the event related to positive results for the sponsor?

The transfer of positive brand image from the sponsored event to the sponsor is now one of the main reasons cited for engaging in event sponsorship activity. Beyond just simple brand associations though, it has been recognised that patrons often feel "goodwill" towards certain sponsored events and these feelings could also be transferred to enhance sponsorship outcomes. This paper reports on an email survey of over 300 patrons of a non-profit Arts Festival, examining whether "goodwill" can influence sponsorship effectiveness. Specifically, the focus here is on the relationship between positive attitudes toward the event and sponsorship outcomes. The findings suggest that satisfaction with the event is correlated positively with sponsor recall but not recognition. Those with higher degrees of "goodwill" towards the event did have more positive attitudes towards the sponsor and were more likely to recall and recognise sponsors correctly.
