Re-viewing Adult Learning: A Collaborative Self-Directed Learning Model for Adult Educators

The CSDL model for adult education suggests the incorporation of autonomy and collaboration to traditional SDL. An exploratry model that addresses individual and group choice, control, resources and benefits is proposed

Perceptions of Medical Students of the Role of the Speech-language Pathologist in HIV/AIDS Intervention

Survey research was utilized to explore Medical students’ perceptions of Speech-Language Pathologists’(SLP) and Medical Practitioner’s roles in meeting the healthcare needs of people living with HIV/AIDS(PLWHA). Results identified participants’ knowledge and perceptions. Recommendations suggest interprofessional education and training for both professions, at the pre-professional and professional levels

Mapping canopy nitrogen-scapes to assess foraging habitat for a vulnerable arboreal folivore in mixed-species Eucalyptus forests

Herbivore foraging decisions are closely related to plant nutritional quality. For arboreal folivores with specialized diets, such as the vulnerable greater glider (Petauroides volans), the abundance of suitable forage trees can influence habitat suitability and species occurrence. The ability to model and map foliar nitrogen would therefore enhance our understanding of folivore habitat use at finer scales. We tested whether high-resolution multispectral imagery, collected by a lightweight and low-cost commercial unoccupied aerial vehicle (UAV), could be used to predict total and digestible foliar nitrogen (N and digN) at the tree canopy level and forest stand-scale from leaf-scale chemistry measurements across a gradient of mixed-species Eucalyptus forests in southeastern Australia. We surveyed temperate Eucalyptus forests across an elevational and topographic gradient from sea level to high elevation (50–1200 m a.s.l.) for forest structure, leaf chemistry, and greater glider occurrence. Using measures of multispectral leaf reflectance and spectral indices, we estimated N and digN and mapped N and favorable feeding habitat using machine learning algorithms. Our surveys covered 17 Eucalyptus species ranging in foliar N from 0.63% to 1.92% dry matter (DM) and digN from 0.45% to 1.73% DM. Both multispectral leaf reflectance and spectral indices were strong predictors for N and digN in model cross-validation. At the tree level, 79% of variability between observed and predicted measures of nitrogen was explained. A spatial supervised classification model correctly identified 80% of canopy pixels associated with high N concentrations (≥1% DM). We developed a successful method for estimating foliar nitrogen of a range of temperate Eucalyptus species using UAV multispectral imagery at the tree canopy level and stand scale. The ability to spatially quantify feeding habitat using UAV imagery allows remote assessments of greater glider habitat at a scale relevant to support ground surveys, management, and conservation for the vulnerable greater glider across southeastern Australia

We are playing football: Seeing the game on Panapompom, PNG

© Royal Anthropological Institute 2011.This article is about football, played by men from Panapompom in Papua New Guinea's Milne Bay province. Football is problematic not because it is culturally appropriated or modified, but rather because Panapompom desired accurately to reproduce the appearance of the international game. As such it questions conventional frames of reference. An interpretation in terms of culture obscures Panapompom interests in football: its globally recognizable character. It mattered profoundly that Panapompom people played football. Yet framing football as a universal sporting institution is equally inadequate, erasing the specific political project that was embedded in the game. Displacing the interpretative framings, I argue that football itself provides a context in which Panapompom people can judge themselves in relation to others, who are defined in terms of colonial and postcolonial discourses on ‘development’. Taking football as a contextualizing image, Panapompom people appear in distinctive ways in the field of relationships that it defines.ESR
