The combined effect of light intensity and temperature on the chlorophyll and carotenoid pigments of phytoplankton

Chlorophyll a and other photosynthetic pigments are used as indicators of phytoplankton biomass, composition and physiological state. Extraction and HPLC procedures were developed to analyse for chlorophyll and carotenoid pigments. The effect of the environment on pigment production must be quantified before the pigments can be used to accurately estimate biomass or quantitatively describe phytoplankton composition.

Interpersonal features of talk in interpreted medical consultations

This linguistic study examined the interpersonal features of the talk between doctors and patients in consultations where a professional medical interpreter was required for them to communicate. Such features affect the relationship between doctor and patient and can impact on medical outcomes. The findings will assist interpreters and doctors in talking to patients and forms part of a larger project to develop a theory of medical interpreting.

Factors influencing consistency of triage using the Australasian triage scale : implications for guideline development

Objective: To examine the influence of the nurse, the type of patient presentation and the level of hospital service on consistency of triage using the Australasian Triage Scale.

Methods: A secondary analysis of survey data was conducted. The main study was undertaken to measure the reliability of 237 scenarios for inclusion in a national training programme. Nurses were recruited from a quota sample of Australian ED according to peer group. Analysis was performed to determine concordance: the percentage of responses in the modal triage category. Analysis of variance (anova) and Pearson correlations were used to investigate associations between the explanatory variables and concordance.

Results: A total of 42/50 (84%) participants returned questionnaires, providing 9946 scenario responses for analysis. Significant differences in concordance were observed by variables describing the type of patient presentation and level of urgency. Mean scores for the comparison group (adult pain; 70.7%) were higher than the groups involving a mental health or pregnancy presentations (61.4%; P≤ 0.001; 65.0%; P= 0.02). Modal responses at the extreme ends of the scale were higher than in the middle categories (P≤ 0.001). There was a significant main effect on concordance by type of service according to peer group (P= 0.03). Of the nine variables that described nurse characteristics, age was the only factor to influence the outcome (P= 0.05).

Conclusion: We identified significant problems with the consistency of triage for mental health and pregnancy presentations. Further research is needed to improve the guidelines on the implementation of the Australasian Triage Scale for these populations.

The communication skills used by deaf children and their hearing peers in a question-and-answer game context

Communication is frequently characterized by a sequence of questions and answers. Little is known about how well students who are deaf or hard of hearing (deaf/HH) understand their hearing classmates in the context of an inclusive setting. This study explored the communication skills used by deaf/HH children when asking and answering questions in a “trivia” game with their hearing peers. Thirty-four children with normal hearing and 34 children with a hearing loss ranging from mild to profound (>90 dB HL) participated in this study. Each of the 34 dyads included 1 child with normal hearing and 1 child with hearing loss, matched by gender and grade level at school. Dyads were videotaped and analyzed. Pairs were compared in terms of their capacity to repeat the question, strategies used to seek information, and accuracy of responses. Results showed that the group of hearing children was able to repeat more questions verbatim compared to the deaf/HH children. The deaf/HH group required a significantly greater number of repetitions, sought a greater number of general clarifications, and correctly answered more questions compared with the group of hearing children. The implications of these findings are discussed in terms of peer communication and pragmatic skill development.

Planning practices in Australian family businesses

Australian family businesses have a poor track record of undertaking formal business planning. This paper reports on the business planning behaviour of
Australian family businesses from a survey of 5,000 businesses across all types and sizes of industries. Our survey found that around one-third of family
businesses undertake formal planning activities. Thus, there has been no improvement in family business planning practices from that reported in 2003. The reluctance of Australian family businesses to undertake contingency and risk planning, as well as human resources planning, leaves Australian family businesses highly exposed in these difficult economic times.

Corporate social responsibility reporting : a business strategy by Australian banks?

The growth of voluntary corporate social responsibility (CSR) reporting reflects society's expectations for business to set higher ethical standards and to undertake business in a way that meets the profit imperative (the bottom line). Additionally, the community expects socially and environmentally responsible behaviour practices; the so-called triple bottom line approach. The paper briefly reviews the development of corporate social responsibility reporting from the perspective of two large Australian banks and attempts to understand their motivation for voluntary disclosure. Stakeholder theory and game theory provide a means to analyse why banks undertake CSR reporting. The paper compares Westpac and National Australia Bank's CSR reporting over the period 2004-2005 utilising external rating agencies and CSR reports to determine the extent of disclosure in relation to employees, environment, community and customers. The paper concludes with a discussion of the pros and cons of CSR, the role of regulation and recommendations for future policy direction.
