Plasma coagulation factor VII activity and its corrlates in healthy men

Objective: The aim of this study was to investigate the plasma coagulation factor VII activity and its correlates in healthy Australian men.
Design: Cross-sectional study.
Setting: Free living subjects.
Subjects: A total of 139 healthy Australian males aged 20–55 y with widely varying intakes of individual fatty acids.
Outcome measures: The concentration of phospholipid fatty acids and the parameters of biochemistry were analysed by standard methods. Citrated plasma factor VII activity was measured by using the ACL 200 system with commercially available kits.
Results: In the stepwise multiple regression, controlled for age, body mass index and dietary groups, the two most important variables of factor VII activity were selected in the forward entry model with R2¼0.474 and Po0.0001 from 19 independent variables, which were significantly correlated with plasma factor VII activity in age-adjusted bivariate analysis where significance was considered at Po0.01. Plasma factor VII activity was strongly negatively correlated with prothrombin time (PT) (Std. Coeff. -0.550), and significantly positively correlated with plasma phospholipid (PL) stearic acid (Std. Coeff. 0.285).
Conclusions: Increased factor VII activity was associated with shortening of PT. All types of fatty-acid concentrations of PLs were
significantly positively correlated with factor VII activity; however, stearic acid was more potent than other fatty acids in healthy Australian men.

Comparison of two modes of delivery of first aid training including basic life support

Aims: Flexible-learning first aid courses are increasingly common due to reduced classroom contact time. This study compared retention of first aid knowledge and basic life support (BLS) skills three months after a two-day, classroom-based first aid course (STD) to one utilizing on-line theory learning at home followed by one day of classroom training (FLEX).
Methods: In this prospective randomized controlled trial, 256 participants with internet access and no first aid related training for at least five years were randomly allocated to a STD or FLEX course. Assessment was conducted immediately after training and again three months later. Each participant was allocated a theory and a BLS score, which were summed and averaged to create an equally-weighted ‘combined score’
of first aid knowledge and skills.
Results: There was no significant difference in theory scores between the STD and FLEX groups immediately after training and after three months. STD participants had significantly higher BLS scores immediately after training (p = 0.001) and three months later (p = 0.046). Males had significantly higher BLS scores after training (p < 0.001), but not three months later (p = 0.02). Participants older than 46 years had significantly lower BLS scores than younger participants (p < 0.001). There was no significant difference in combined scores between the STD and FLEX groups or between genders, education or age groups either immediately after training or three months later.
Conclusion: After replacing one day of classroom-based training with on-line theory training, there was no significant difference in the first aid competencies of the study population, as measured by an equallyweighted
combined score of basic life support and first aid theory.

Height, aging and cognitive abilities across Europe

Previous research has found that as a marker of childhood circumstances, height is correlated with cognitive functioning at older ages. Using data from the Survey of Health, Ageing, and Retirement in Europe (SHARE) and about 17,000 respondents from 11 countries, we find that height is positively and significantly associated with cognitive functioning in later life despite controlling for a myriad of possible confounding factors. A 10 cm increase in height is associated with a 0.04 standard deviation increase in a summary cognitive score (mean 0.02, std. dev. 0.77). We find that being born in a country where the infant mortality rate at the time of birth is high has a negative and significant influence on cognitive functioning in later life. A 10% increase in the infant mortality rate is associated with a 0.1 standard deviation decrease in the summary cognitive score. We also find some evidence that height serves as a protective factor against age related deterioration in cognitive functioning. For persons of average stature, age related decreases in cognition scores are 3–5 percentage points smaller if they move up a quartile in the height distribution. Our results also suggest that there is a significant positive association between height and cognitive abilities across countries for this pre-1950 birth cohort of respondents, with correlations ranging from 0.4 to 0.8.

A shareholder’s contractual right to a dividend and a company’s oppressive conduct in withholding dividend payments: Sumiseki Materials Co Ltd v Wambo Coal Pty Ltd

Traditionally, a shareholder’s expectation of receiving a dividend has been limited by the discretion the board of directors has to recommend the appropriate amount of payment as a dividend. As a general rule, shareholders will only be entitled to a dividend after the dividend is declared (normally, at the general meeting), or when the actual date arrives for the dividend to be paid. Because courts were traditionally reluctant to interfere with the internal management of companies, the remedies available to shareholders to compel a company to declare a dividend were very limited. As a result, if the directors have decided to withhold dividend payment, courts will only make an order requiring dividends to be paid under very exceptional circumstances. In this article, the authors discuss the case of Sumiseki Materials Co Ltd v Wambo Coal Pty Ltd [2013] NSWSC 235, which is exceptional for the court’s recognition of a shareholder’s contractual right to a dividend. The article analyses the court’s approach, which found that withholding dividend payments was oppressive and unfairly prejudicial conduct of the company. It also discusses the significance of shareh9olders entrenching their rights in a company’s constitution, irrespective of the fact that a company has a statutory right to alter its constitution by way of a special resolution.

Food concerns and support for environmental food policies and purchasing.

Consumer support for pro environmental food policies and food purchasing are important for the adoption of successful environmental policies. This paper examines consumers' views of food policy options as their predisposition to purchase pro environmental foods along with their likely demographic, educational and cognitive antecedents including food and environmental concerns and universalism values (relating to care for others and the environment). An online survey to assess these constructs was conducted among 2204 Australian adults in November 2011. The findings showed strong levels of support for both environmental food policies (50%-78% support) and pro environmental food purchasing (51%-69% intending to purchase pro environmental foods). Confirmatory factor analysis and structural equation modelling showed that different cognitive mediators exist along pathways between demographics and the two outcome variables. Support for food policy was positively related to food and environment concerns (std. Beta = 0.25), universalism (0.41), perceived control (0.07), and regulatory issues (0.64 but negatively with food security issues (-0.37). Environment purchasing intentions were positively linked to food and nutrition concerns (0.13), food and environment concerns (0.24), food safety concerns (0.19), food and animal welfare concerns (0.16), universalism (0.25), female gender (0.05), education (0.04), and perceived influence over the food system (0.17). In addition, health study in years 11 and 12 was positively related to the beginning of both of these pathways (0.07 for each). The results are discussed in relation to the opportunities that communications based on the mediating variables offer for the promotion of environmental food policies and purchasing.

Prosecutors’ perceptions of the utility of video-evidence for adult complainants of sexual assault

Playing an adult sexual complainant’s video-recorded police interview as the basis for his or her evidence-in-chief is a reform Australia could adopt to help improve criminal justice responses to these cases. This article presents a qualitative evaluation of prosecutor’s support for this reform and their views about what conditions would determine its utility. Focus groups were held with 13 prosecutors from across New Zealand (which already has this reform) and Australia. Collectively, prosecutors supported the availability of video-evidence for adult complainants. They perceived the utility of this reform depends on the following conditions: (1) the quality of the police interview; (2) how credibly the complainant presents on video; (3) contextual factors that influence the complainant’s ability to give live evidence; and (4) the degree of stakeholder support. These findings suggest that Australia should extend video-evidence to adult complainants of sexual assault guided by careful planning aroundthese four areas.
