Environmental education : from policy to practice

The field of environmental education faces a process of continuous conceptual reconstruction that is underpinned by the complexity of the social and political changes occurring throughout the world as consequences of environmental crises and the different perspectives through which they are understood in different contexts. Thus there is a need to review and reflect on the meanings of environmental education, its theory and its practice. To address such issues the seminar, 'Environmental Education: from policy to practice', was held at King's College London in March 2001, under the sponsorship of the British Council and directed by Justin Dillon. The seminar brought together environmental educators from a broad spectrum--policy developers, researchers and practitioners--from Belize, Botswana, Brazil, Canada, Colombia, Cyprus, the Czech Republic, India, Mexico, the Russian Federation, Singapore, Swaziland, Sweden, the United Kingdom, the United States of America, Venezuela and Zimbabwe. During a thought-provoking six days the seminar discussed a diverse range of ideas about the current trends and future practices in environmental education. In this report we present our 'reading' and reflection on two major aspects of the discussion: the meanings of environmental education and education for sustainable development in different cultures and contexts. This we do from our own positions as academics working on environmental education in Latin American contexts.

Undercarboxylated osteocalcin, muscle strength and indices of bone health in older women

We investigated the association between undercarboxylated osteocalcin (ucOC) and lower-limb muscle strength in women over the age of 70years. The study also aims to confirm the association between bone turnover markers and heel ultrasound measures. A post-hoc analysis using data collected as part of a randomized placebo-controlled trial of vitamin D supplementation. An immunoassay was used to quantify total OC (tOC), with hydroxyapatite pre-treatment for ucOC. We determined associations of absolute and relative (ucOC/tOC; ucOC%) measures of ucOC with lower-limb muscle strength, heel ultrasound measures of speed of sound (SOS) and broadband ultrasound attenuation (BUA), bone turnover markers (BTMs; P1NP and CTx) and the acute phase protein alpha-1-antichymotrypsin (α-ACT). ucOC%, but not absolute ucOC concentration, was positively associated with hip flexor, hip abductor and quadriceps muscle strength (all p<0.05). ucOC% was negatively associated with α-ACT (β-coefficient=-0.24, p=0.02). tOC was positively associated with both P1NP and CTx (p<0.001). For each per unit increase in tOC (μg/L) there was a corresponding lower BUA, SOS and SI (β-coefficient = -0.28; -0.23 and -0.23, respectively; all p<0.04). In conclusion, ucOC% is positively associated with muscle strength and negatively associated with α-ACT. These data support a role for ucOC in musculoskeletal interactions in humans. Whilst tOC is associated with bone health, ucOC% and ucOC may also be linked to falls and fracture risk by influencing muscle function.

Changes in quality of life associated with fragility fractures: Australian arm of the International Cost and Utility Related to Osteoporotic Fractures Study (AusICUROS).

We investigated change in health-related quality of life due to fracture in Australian adults aged over 50 years. Fractures reduce quality of life with the loss sustained at least over 12 months. At a population level, the loss was equivalent to 65 days in full health per fracture.
