The article focuses on the trial of Quantas Airways Ltd. and its decisions by the Australian Competition Tribunal which focuses on the analysis of public and private benefits and the differences between them. It discusses the decisions by the Canadian Competition Tribunal in the trial of Superior Propane Inc. It further focuses on merger authorization decisions and the welfare standards employed in making these decisions. It suggests the need of interpreting public benefits in the decisions.

CD22 has been suggested to contribute to Alzheimer's disease (AD) pathogenesis by inhibiting microglial amyloid β (Aβ) phagocytosis. Soluble CD22 (sCD22) generated by cleavage from cell membranes may be a marker of inflammation and microglial dysfunction; but alterations of sCD22 levels in AD and their correlation with AD biomarkers remain unclear. Plasma sCD22 levels were measured in cognitively normal non-AD participants and patients with preclinical AD and AD dementia from a Chinese cohort and the Australian Imaging, Biomarkers and Lifestyle Flagship Study of Ageing. Plasma sCD22 levels were elevated in patients with preclinical and dementia AD. Plasma sCD22 levels were negatively correlated with cerebrospinal fluid (CSF) Aβ42 levels and Aβ42/Aβ40, and positively correlated with CSF phosphorylated tau levels and brain Aβ burden, but negatively correlated with cognitive function. Moreover, higher plasma sCD22 levels were associated with faster cognitive decline during follow-up. These findings suggest that CD22 plays important roles in AD development, and that sCD22 is a potential biomarker for AD.

Introduction: The importance of the nursing role in chronic heart failure (CHF) management is increasingly recognised. With the recent release of the National Health and Hospitals Reform Commission (NHHRC) report in Australia, a review of nursing roles in CHF management is timely and appropriate., Aim: This paper aims to discuss the implications of the NHHRC report and nursing roles in the context of CHF management in Australia., Method: The electronic databases, Thomson Rheuters Web of Knowledge, Scopus and the Cumulative Index to Nursing and Allied Health Literature (CINAHL), were searched using keywords including; "heart failure", "management", "Australia" and "nursing". In addition policy documents were reviewed including statements and reports from key professional organisations and Government Departments to identify issues impacting on nursing roles in CHF management., Results: There is a growing need for the prevention and control of chronic conditions, such as CHF. This involves an increasing emphasis on specialist cardiovascular nurses in community based settings, both in outreach and inreach health service models. This review has highlighted the need to base nursing roles on evidence based principles and identify the importance of the nursing role in coordinating and managing CHF care in both independent and collaborative practice settings., Conclusion: The importance of the nursing role in early chronic disease symptom recognition and implementing strategies to prevent further deterioration of individuals is crucial to improving health outcomes. Consideration should be given to ensure that evidence based principles are adopted in models of nursing care., (Copyright © 2010 Australian College of Critical Care Nurses Ltd.

There is an increasing need to address the educational needs of students with English as a second language. The authors assessed the value of a Web-based activity to meet the needs of students with English as a second language in a bioscience subject. Using telephone contact, we interviewed 21 Chinese students, 24 non-Chinese students with English as a second language, and 7 native English-speaking students to identify the perception of the value of the intervention. Four themes emerged from the qualitative data: (1) Language is a barrier to achievement and affects self-confidence; (2) Enhancement intervention promoted autonomous learning; (3) Focusing on the spoken word increases interaction capacity and self-confidence; (4) Assessment and examination drive receptivity and sense of importance. Targeted strategies to promote language acculturation and acquisition are valued by students. Linking language acquisition skills to assessment tasks is likely to leverage improvements in competence., (Copyright 2011, SLACK Incorporated.)
