Young people with intellectual disabilities attending mainstream and segregated schooling: perceived stigma, social comparison and future aspirations

Mainstream schooling is a key policy in the promotion of social inclusion of young people with learning disabilities. Yet there is limited evidence about the school experience of young people about to leave mainstream as compared with segregated education, and how it impacts on their relative view of self and future aspirations. Sixty young people with mild to moderate intellectual disabilities in their final year of secondary school participated in this study. Twenty-eight individuals came from mainstream schools and 32 attended segregated school. They completed a series of self-report measures on perceptions of stigma, social comparison to a more disabled and non-disabled peer and the likelihood involved in attaining their future goals. The majority of participants from both groups reported experiencing stigmatized treatment in the local area where they lived. The mainstream group reported significant additional stigma at school. In terms of social comparisons, both groups compared themselves positively with a more disabled peer and with a non-disabled peer. While the mainstream pupils had more ambitious work-related aspirations, both groups felt it equally likely that they would attain their future goals. Although the participants from segregated schools came from significantly more deprived areas and had lower scores on tests of cognitive functioning, neither of these factors appeared to have an impact on their experience of stigma, social comparisons or future aspirations. Irrespective of schooling environment, the young people appeared to be able to cope with the threats to their identities and retained a sense of optimism about their future. Nevertheless, negative treatment reported by the children was a serious source of concern and there is a need for schools to promote the emotional well-being of pupils with intellectual disabilities.

Iron and zinc status in multiple sclerosis patients with pressure sores

Measurements of weighted dietary intakes and plasma determinations of albumin, iron, zinc, ascorbic acid and TIBC were carried out on twenty female multiple sclerosis patients in a long-stay hospital for disabled people. The group included ten patients with a recent history of pressure sores, closely matched with ten patients without pressure sores. Mean daily intake of carbohydrate was found to be higher in the non-pressure sore group whilst intake of zinc was lower in this group. Intakes of all other nutrients were comparable between the two groups. For both groups, intakes of energy, folate, vitamin D, iron and zinc were less than recommended values. Mean plasma levels of albumin and iron were towards the lower limit of the normal range, whilst that for zinc was considerably less than the normal range. Plasma TIBC was slightly above the normal range. Levels of plasma iron and zinc were significantly lower in the pressure sore group. The data indicate that severely disabled hospitalized patients with multiple sclerosis may be at risk of poor nutritional status. The results suggest that in the presence of pressure sores, there are increased requirements for specific nutrients, notably zinc and iron. Consideration is given to the possible value of supplementation of these individuals.

Patents for plants: context and current status

One of the important themes in any discussion concerning the application of genetic transformation technology in horticulture or elsewhere is the role of Intellectual Property Rights (IPR). This term covers both the content of patents and the confidential expertise, usually related to methodology and referred to as “Trade Secrets”. This review will explain the concepts behind patent protection, and will discuss the wide-ranging scope of existing patents that cover novel genotypes of plants as well as all aspects of transgenic technology, from selectable markers and novel promoters to methods of gene introduction. Although few of these patents have any significant commercial value there are a small number of key patents that may restrict the “freedom to operate” of any company seeking to exploit the methods in the production of transgenic varieties. Over the last twenty years, these restrictions have forced extensive cross-licensing between ag-biotech companies and have been one of the driving forces behind the consolidation of these companies. Although such issues may have limited relevance in the horticultural sector, and are often considered to be of little interest to the academic scientist working in the public sector, they are of great importance in any debate about the role of “public-good breeding” and of the relationship between the public and private sectors.

Contested H2O: science, policy and politics in water resources management in Chile

This paper critically explores the politics that mediate the use of environmental science assessments as the basis of resource management policy. Drawing on recent literature in the political ecology tradition that has emphasised the politicised nature of the production and use of scientific knowledge in environmental management, the paper analyses a hydrological assessment in a small river basin in Chile, undertaken in response to concerns over the possible overexploitation of groundwater resources. The case study illustrates the limitations of an approach based predominantly on hydrogeological modelling to ascertain the effects of increased groundwater abstraction. In particular, it identifies the subjective ways in which the assessment was interpreted and used by the state water resources agency to underpin water allocation decisions in accordance with its own interests, and the role that a desocialised assessment played in reproducing unequal patterns of resource use and configuring uneven waterscapes. Nevertheless, as Chile’s ‘neoliberal’ political-economic framework privileges the role of science and technocracy, producing other forms of environmental knowledge to complement environmental science is likely to be contentious. In conclusion, the paper considers the potential of mobilising the concept of the hydrosocial cycle to further critically engage with environmental science.

Understanding the long term success of UK construction firms: the extent and role of 'hidden' corporate social responsibility

The construction sector is often described as lagging behind other major industries. At first this appears fair when considering the concept of corporate social responsibility (CSR). It is argued that CSR is ill-defined, with firms struggling to make sense of and engage with it. Literature suggests that the short-termism view of construction firms renders the long-term, triple-bottom-line principle of CSR untenable. This seems to be borne out by literature indicating that construction firms typically adopt a compliance-based approach to CSR instead of discretionary CSR which is regarded as adding most value to firms and benefiting the broadest group of stakeholders. However, this research conducted in the UK using a regional construction firm offers a counter argument whereby discretionary CSR approaches are well embedded and enacted within the firms’ business operations even though they are not formally articulated as CSR strategies and thus remain 'hidden'. This raises questions in the current CSR debate. First, is ‘hidden’ CSR relevant to the long term success of construction firms? and to what extent do these firms need to reinvent themselves to formally take advantage of the CSR agenda?

Effects of chronic consumption of fruit and vegetable puree-based drinks on vasodilation, plasma oxidative stability and antioxidant status

Background: Fruit and vegetable-rich diets are associated with a reduced cardiovascular disease (CVD) risk. This protective effect may be a result of the phytochemicals present within fruits and vegetables (F&V). However, there can be considerable variation in the content of phytochemical composition of whole F&V depending on growing location, cultivar, season and agricultural practices, etc. Therefore, the present study investigated the effects of consuming fruits and vegetables as puree-based drinks (FVPD) daily on vasodilation, phytochemical bioavailability, antioxidant status and other CVD risk factors. FVPD was chosen to provide a standardised source of F&V material that could be delivered from the same batch to all subjects during each treatment arm of the study. Methods: Thirty-nine subjects completed the randomised, controlled, cross-over dietary intervention. Subjects were randomised to consume 200 mL of FVPD (or fruit-flavoured control), daily for 6 weeks with an 8-week washout period between treatments. Dietary intake was measured using two 5-day diet records during each cross-over arm of the study. Blood and urine samples were collected before and after each intervention and vasodilation assessed in 19 subjects using laser Doppler imaging with iontophoresis. Results: FVPD significantly increased dietary vitamin C and carotenoids (P < 0.001), and concomitantly increased plasma α- and β-carotene (P < 0.001) with a near-significant increase in endothelium-dependent vasodilation (P = 0.060). Conclusions: Overall, the findings obtained in the present study showed that FVPD were a useful vehicle to increase fruit and vegetable intake, significantly increasing dietary and plasma phytochemical concentrations with a trend towards increased endothelium-dependent vasodilation.

Effects of acute consumption of a fruit and vegetable puree-based drink on vasodilation and oxidative status

Epidemiological studies indicate that diets rich in fruits and vegetables (F&V) are protective against cardiovascular diseases (CVD). Pureed F&V products retain many beneficial components, including flavonoids, carotenoids, vitamin C and dietary fibres. This study aimed to establish the physiological effects of acute ingestion of F&V puree-based drink (FVPD) on vasodilation, antioxidant status, phytochemical bioavailability and other CVD risk factors. 24 Subjects, aged 30-70 years, completed the randomised, single-blind, controlled, crossover test meal study. Subjects consumed 400 ml FVPD, or fruit-flavoured sugar-matched control, after following a low-flavonoid diet for 5 days. Blood and urine samples were collected throughout the study day and vascular reactivity was assessed at 90-minute intervals using laser Doppler iontophoresis (LDI). FVPD significantly increased plasma vitamin C (P=0.002) and total nitrate/nitrite (P=0.001) concentrations. There was a near significant time by treatment effect on ex vivo LDL oxidation (P=0.068), with a longer lag phase after consuming FVPD. During the 6 hours after juice consumption the antioxidant capacity of plasma increased significantly (P=0.003) and there was a simultaneous increase in plasma and urinary phenolic metabolites (P<0.05). There were significantly lower glucose and insulin peaks after ingestion of FVPD compared with control (P=0.019 and P=0.003) and a trend towards increased endothelium-dependent vasodilation following FVPD consumption (P=0.061). Overall, FVPD consumption significantly increased plasma vitamin C and total nitrate/nitrite concentrations, with a trend towards increased endothelium-dependent vasodilation. Pureed F&V products are useful vehicles for increasing micronutrient status, plasma antioxidant capacity and in vivo NO generation, which may contribute to CVD risk reduction.
