Critical infrastructure protection, modelling and management: an Australian commercial case study

This research extends upon the previous work of Pye and Warren (2005) and presents a refinement of the previously proposed critical infrastructure model to enhance further our understanding and apprecication of where the likely inter-play and existance of dependency relationships between infrastructures coexist.

These associations are presented as a number of linkages that exist within each sector of Australia'a critical infrastructure, which is then extended further to the modelling of dependency inter-relationships that exist between critical infrastructures itilising Petri Nets.  The recognition and identification of such reliance relationships between critical infrastructures is necessary to allow both infrastructure owners and the government to identify and effectively manage and maintain the security, stability and availability of their particular critical infrastructure against potential scenario driven effects.  These issues are reflected within a case study as modelled using the Petri Net approach to encapsulate the issues of reliance relationships by drawing upon an Australian commercial case study.

Derivative actions as a mechanism for the protection of minority shareholders in China: a result of convergence or divergence

The protection of minority shareholders has become one of the key features of company law reform in many countries in recent years. Various mechanisms have been created to achieve this objective. Australia has introduced the statutory derivative action procedure mainly based on models drawn from Canada and New Zealand; this provision was inserted into the Corporations Act in March 2000. China has also adopted a similar mechanism – known as the shareholder representative action; this scheme was based upon China’s understanding of statutory derivative actions in Western countries. China’s derivative action mechanism is reflected in amendments to the 2005 PRC Company Law and 2005 Securities Law that both were passed on 27 October 2005 and came into effective on 1 January 2006. The development of statutory derivative actions in different countries demonstrates the interaction between forces of convergence and divergence in company law reforms. This article reviews different mechanisms adopted in the Chinese law for the protection of minority shareholders. It especially focuses on an analysis of the nature of the shareholder representative action and the procedures for its utilisation in China – the equivalent to Western countries’ derivative actions. In comparison with statutory derivative actions in Australia, this article argues that the concept of the shareholder representative action in China rests upon a misunderstanding of Western derivative actions; this has involved a compromise between the dire need to protect shareholders and the ambiguities of a weak court system. As a consequence, China’s reforms in this area are largely a tentative gesture and are therefore unlikely to be very effective.

Protection for sale in a developing country : democracy vs. dictatorship

For a "genuine" small open economy that has experienced both dictatorship and democracy, we find support for the predictions of the Grossman-Helpman (1994) "Protection for Sale" model. In contrast to previous studies, we use various protection measures (including tariffs, the direct measure of the theoretical model) and perform both single-year and panel regressions. Using Turkish industry-level data, the government's weight on welfare is estimated to be much larger than that on contributions. More importantly, we find that this weight is generally higher for the democratic regime than for dictatorship.

Can we obtain realistic parameter estimates for the 'protection for sale' model?

In the Grossman and Helpman (1994) model of endogenous trade protection, sectoral lobbies try to influence an incumbent government that maximizes a weighted sum of political contributions and aggregate welfare. We empirically investigate this model using U.S. and Turkish data. Our specification is more tightly tied to theory than those in existing studies. Additionally, we assume all specific‐factor owners to be organized into different lobbies. These changes, validated by hypothesis tests, yield more realistic parameter estimates of the government's concern for aggregate welfare and of the fraction of population organized into lobbies.

Australian adolescents' sun protection behavior : who are we kidding?

Purpose
To examine the influence of tan preference and skin type on sun protection behaviors of Australian adolescents.

Methods
The Australian Secondary School Alcohol and Drug Questionnaires were conducted in 1993, 1996, 1999 and 2002 among randomly selected students aged 12–-17. Schools were randomly selected from each education sector in each state. The self-administered questionnaire contained questions about tan preferences, skin type and usual SunSmart behavior (use of sunscreen, hats and covering clothing).

Results
The routine use of SunSmart behavior was low in all survey years. There was a significant decrease over time in the proportion of students who practiced SunSmart behavior, with prevalence rates lower in 2002 than in any other survey year (males: p < 0.01 and females: p < 0.01). As desire for a tan increased, routine practice of SunSmart behaviors decreased. Across the four survey periods, male (p < 0.01) and female (p < 0.01) students who preferred no tan were significantly more likely to practice SunSmart behavior than students who preferred any sort of tan. Across the four survey years, male (p < 0.01) and female (p < 0.01) students with skin that ‘just burns’ were most likely to routinely practice SunSmart behavior.

Conclusions
Sun protection practices among adolescents have continued to decline significantly over time. Future educational programs require an innovative approach to modify adolescent behaviors in relation to sun exposure and sun protection.

Sun exposure and sun protection behaviours among young adult sport competitors

Objective: To explore the relationship between sun protection and physical activity in young adults (18-30 years) involved in four organised sports.

Methods: Participants (n=237) in field hockey, soccer, tennis and surf sports completed a self-administered survey on demographic and sun-protective behaviours while playing sport. Differences in sun-protective behaviour were explored by sport and by gender.

Results: Sunburn during the previous sporting season was high (69%). There were differences between sports for sunburn, sunscreen use and reapplication of sunscreen. Lifesaving had the highest rates compared with the other three sports. Hats and sunglasses worn by participants varied significantly by sports. A greater proportion of soccer and hockey players indicated they were not allowed to wear a hat or sunglasses during competition. For all sports, competition was played mainly in the open with no shade provision for competitors while they were playing. There were some gender differences within each of the sports. Female soccer and tennis players were more likely to wear sunscreen compared with males. Female hockey players were more likely to wear a hat compared with males.

Conclusions: Our findings highlight that there is still room for improvement in sun-protective behaviours among young adult sport competitors. There is a need for a systematic approach to sun protection in the sporting environments of young adults.

Implications: Health promotion efforts to increase physical activity need to be paired with sun protection messages.

The importance of human FcyRI in mediating protection to malaria

The success of passive immunization suggests that antibody-based therapies will be effective at controlling malaria. We describe the development of fully human antibodies specific for Plasmodium falciparum by antibody repertoire cloning from phage display libraries generated from immune Gambian adults. Although these novel reagents bind with strong affinity to malaria parasites, it remains unclear if in vitro assays are predictive of functional immunity in humans, due to the lack of suitable animal models permissive for P. falciparum. A potentially useful solution described herein allows the antimalarial efficacy of human antibodies to be determined using rodent malaria parasites transgenic for P. falciparum antigens in mice also transgenic for human Fc-receptors. These human IgG1s cured animals of an otherwise lethal malaria infection, and protection was crucially dependent on human FcγRI. This important finding documents the capacity of FcγRI to mediate potent antimalaria immunity and supports the development of FcγRI-directed therapy for human malaria.

Promoting comprehensive sun protection policies and practices in outdoor sports: a qualitative study of perceived priorities and practicalities

Sun protection policies, environments, practices, and attitudes in sporting club contexts might be significant determinants of sun exposure among adult sporting participants. Face-to-face interviews, using standardised, open-ended questions were conducted with 20 club officials from four sports: soccer, hockey, tennis and surf lifesaving. Thematic content analysis identified a number of salient themes. Formal sun protection policies were well-implemented in surf lifesaving, but less so in soccer, hockey and tennis clubs, which often had informal sun protection practices in place. Officials perceived sun protection to be important, which was related to perceived exposure levels, the type of sport, length of time played and the season. Consistent logistical and practical considerations emerged, including limited resources, availability of shade, and lack of control over sporting facilities, uniform regulations and games scheduling. Sun protection efforts often focused on children more than adult players. Reciprocal responsibility was an important theme, where it was perceived that responsibility for sun protection should be equally shared between the club and the member. In this study it was found that reciprocal responsibility, duty of care and sport-specific practical requirements might significantly influence the success of policy, environmental and education initiatives for sun protection in sporting settings.

Who is responsible for the protection of children? Implicit and explicit interpretations of marketing messages

In this paper, we examine ethical issues related to advertising to children in light of evidence that people can hold ‘implicit’ as well as ‘explicit’ consumer attitudes. From a review of the important features of implicit versus explicit attitudes, we hypothesise three important features of implicit consumer attitudes in children. First, we suggest they are likely to be acquired automatically from, in part, exposure to marketing messages. Second, we predict that these attitudes will be resistant to change through reflection or reason by the child or other person. Third, we hypothesise that children’s implicit consumer attitudes will be powerful predictors of their consumer choices in many situations. We discuss the implications for the ethics of marketing to children, and propose a research framework to begin investigating this important issue.

Including teachers as 'real' partners in child protection

Simultaneous downsizing of child protection services and increasing numbers of child abuse notifications often result in many notifications remaining un-investigated. One possible solution to this problem is to extend the capacity of the child protection system by delegating some of the tasks commonly undertaken by child protection workers to allied professionals. One such group of allied professionals is teachers. In the past, teachers have been recognised for their unique role in notifying suspicions of abuse, however, education professionals are often overlooked for their potential to contribute more than they currently do to child protection. In this paper we suggest that teachers can be included as 'real' and credible partners in the child protection process in a way not previously considered possible.

Protection versus promotion: an empirical investigation

Using Turkish industry-level data from 1983 to 1990, we find that politically organized industries receive both higher protection and promotion than unorganized ones. Tariff rates are decreasing (increasing) in the import-penetration ratio and the absolute value of the import-demandelasticity for organized (unorganized) industries. Subsidy rates are decreasing (increasing) in the output-supply elasticity for organized (unorganized) industries. The results are consistent with the predictions of the Grossman–Helpman model and its extension in this paper. The mix of protection and promotion is inversely related to the ratio of their respective marginal deadweight cost measures.

A comparison study of cerebral protection using Ginkgo biloba extract and Losartan on stroked rats

It has been well documented that oxidative stress is involved in stroke. Currently, many neuroprotective strategies have been targeted at molecules that are able to act as an oxidant to intervene with free-radical mediated apoptosis in the ischemic penumbra. In particular, natural products which contain antioxidant properties have undoubtedly efficacious for stroke treatment. In the current study, therapeutic effects of Ginkgo biloba extract (EGb) against cerebral protection in Wistar rats underwent middle cerebral artery occlusion (MCAO) was evaluated. A comparison study was conducted by using Losartan, an antihypertensive drug. Gene expression levels of pro-apoptotic genes (AT2 receptor, Fas, Bax and Bcl-xS) have shown to have significant reduction by EGb- and Losartan-treated groups as compared to vehicle group. Significant reduction of immunoreactivity of protein production of these genes, together with least nuclear green fluorescence observed in TUNEL, EGb, as an antioxidant drug, is concluded to have potent and promising therapeutic effect for stroke treatment.

Clinical supervision in child protection for community nurses

Community nurses have been recognized as having a key role in the protection and care of children, particularly in relation to the identification and detection of child abuse. In order to fulfill this role in a competent manner, they need to have access to appropriate supervision. The aim of this paper is to explore community nurses' and health care managers' understanding and experience of clinical supervision in child protection. The findings presented here were collected as part of a larger study commissioned by the Greater Glasgow Primary Health Care National Health Service (NHS) Trust. Ninety-nine nurses and nursing managers were interviewed, either individually or in groups, about their professional involvement in child protection issues and support for their involvement in child protection work, as well as their current knowledge and perceived training needs. The interview data was subjected to a thematic analysis. A lack of consensus was found among nurses and managers in Glasgow as to what constitutes clinical supervision and a good deal of variation in nurses' experiences of clinical supervision in the field of child protection. The historical difficulties with regard to supervision were attributed to several aspects of nursing culture. However, both nurses and managers emphasized the need for formal, regular, systematic supervision for all nurses regardless of their specific role with regard to child protection.

Risk and protection factors for different intensities of adolescent substance use: when does the prevention paradox apply?

The 'Prevention Paradox' applies when low-risk individuals in a population contribute the most cases of a condition or problem behaviour by virtue of their being in the majority, thereby recommending a universal or whole of population approach to prevention. The applicability of a universal as opposed to a targeted high-risk approach to the prevention of youth substance use was examined in two studies of children and adolescents conducted in Victoria, Australia. These studies were reanalysed by recombining developmental, social and individual measures to form cumulative risk indices for substance use. In Study 1, a cross-sectional survey of students, most regular tobacco, alcohol and cannabis use by 15/16-year-olds occurred in the moderate and low-risk groups, recommending a universal prevention strategy . However, the majority of illicit drug use occurred in the highest-risk group (top 15%). Furthermore, in younger age groups both legal and illegal drug use was concentrated mainly in the highest risk group. Study 2 used data from a major longitudinal study where risk factors at around age 11/12 years were used to predict substance use at age 17/18 years. Most students who admitted involvement in frequent smoking, heavy drinking and, although to a lesser degree, cannabis were classified as low or average risk. It is concluded that universal prevention strategies are needed for late adolescent alcohol, tobacco and cannabis use and more targeted strategies for addressing harm related to early age drug use, frequent cannabis use and illegal drug use.
