title: Topical gradients in plant ecology

authors: Laughlin, Daniel C.

subjects: Community ecology

abstract: Plant ecology spans multiple levels of biological organization and spatio-temporal scales, and over four dozen plant ecology textbooks have been published since Warming's (1895) 'Oecology of Plants.' With increasing emphasis on specialization, students and teachers can feel paralyzed by the vast literature, and as such may lack an adequate appreciation of the history of the field. The objective of this study was to derive a comprehensive set of topics that are covered in plant ecology textbooks, and to ask (1) what are the most important topical gradients among textbooks, and (2) has the emphasis of topics changed over time? The NMS ordination determined that the first gradient represented a clear contrast in emphasis on physiological ecology versus community ecology. The second gradient represented a contrast in emphasis on abiotic environmental factors versus biotic factors. Negative interactions, growth, demography, gas exchange, mineral nutrition, stress, diversity, disturbance, herbivory, paleoecology, ecosystem ecology, pollution, and global change have increased in emphasis over time. The increasing reliance on data and the number of authors per textbook illustrates how the discipline has matured into a rigorous quantitative science that requires a diversity of specializations. These results can be used to inform the development of curricula within a single course or across several years of study, and to assist the development of new and revised textbooks. Plant ecologists need to be familiar with this core set of topics in addition to becoming an expert in a few of them.

title: AFOMP POLICY STATEMENT No 1: The role, responsibilities and status of the clinical medical physicist in AFOMP

authors: Ng, K.H.

subjects: clinical medical physicist

abstract: This document is the first of a series of policy statements being issued by the Asia-Oceania Federation of Organizations for Medical Physics (AFOMP). The document was developed by the AFOMP Professional Development Committee (PDC) and was endorsed for official release by AFOMP Council in 2006. The main purpose of the document was to give guidance to AFOMP member organizations on the role and responsibilities of clinical medical physicists. A definition of clinical medical physicist has also been provided. This document discusses the following topics: professional aspects of education and training; responsibilities of the clinical medical physicist; status and organization of the clinical medical physics service and the need for clinical medical physics service.

title: Cultural vehicles and the Māori print media: What cultural concepts are used to communicate health messages to Māori?

authors: Groot, Shiloh Ann Maree

subjects: health

abstract: Existing research indicates that vaccination programmes to prevent Meningococcal disease have low response rates from Māori which contributes to a belief that Māori are apathetic and irresponsible. Our research question was: How do the Māori and community print media facilitate the promotion of Māori cultural concepts as generators of new meaning, particularly with regard to positive Māori health? This study focuses on the recent health
concern of Meningococcal disease. Twenty-four months of Māori and community print media was scanned to identify how Māori cultural concepts are being applied, modified, and operationalised in order to convey and promote positive health in Māori communities. Contrary to what was expected, the Western medical model with integrated Māori concepts was the main cultural frame employed.
