Radiological Risks of Neutron Interrogation of Food

In recent years there has been growing interest in the use of neutron scanning techniques for security. Neutron techniques with a range of energy spectra including thermal, white and fast neutrons have been shown to work in different scenarios. As international interest in neutron scanning increases the risk of activating cargo, especially foodstuffs must be considered. There has been a limited amount of research into the activation of foods by neutron beams and we have sought to improve the amount of information available. In this paper we show that for three important metrics; Activity, Ingestion Dose and Time to Background there is a strong dependence on the food being irradiated and a weak dependence on the energy of irradiation. Previous studies into activation used results based on irradiation of pharmaceuticals as the basis for research into activation of food. The earlier work reports that 24Na production is the dominant threat which motivated the search for 23(n;\gamma)24Na in highly salted foods. We show that 42K can be more significant than 24Na in low salt foods such as Bananas and Potatoes

Vulnerable Users’ Perceptions of Transport Technologies

As the global population continues to grow, age and urbanize, it is vital to provide accessible transport so that neither ageing nor disability constitute barriers to social inclusion. While technology can enhance urban access, there is a need to study the ways by which transport technologies - real-time information, pedestrian navigation, surveillance, and road pricing - could be more effectively adopted by users. The reason for this is that some people, and particularly vulnerable populations, are still likely to reluctantly use (or even avoid using) technologies perceived as 'unknown' and 'complicated'. Based on evidence from British and Swedish case studies on older people's perceptions of the aforementioned transport technologies, as well as on a Swedish case study of visually impaired people's perceptions, this article makes the case that technology is only one tool in a complex socio-technical system, and one which brings challenges. The authors also suggest that although vulnerable populations are not homogeneous when expressing attitudes towards transport technologies, their assessment criteria tend to be 'pro-social' as they usually consider that the societal benefits outweigh the personal benefits. Emphasising aspects linked to the technologies' pro-social potential or relevance to the individual user could increase acceptance

Financing social and cohesion policy in an enlarged EU: plus ça change, plus c'est la même chose?

The development of the Open Method of Coordination, agreement on the Lisbon Agenda and EU enlargement offered the prospect of a new and substantial EU social policy agenda. This article considers EU social and cohesion policies in the context of the recent negotiation of the EU budget for 2007—13. We find the Commission's wish to redistribute EU spending in favour of these policy areas and new member states was thwarted by key political features of EU budget making: CAP spending levels which are downwardly sticky; institutional arrangements which provide for budget making as, at best, a zero-sum game; and the preferences of contributor member states in the EU-15 to contain overall spending while preserving their net budget positions. Questions are thus raised as to the ability of the EU to make any progress, from a budgetary perspective, on the social and cohesion policy agenda in an enlarged EU

Childhood Obesity in Florida: A Narrative Review on Current Trends and Interventions

We examine current research on childhood obesity (CO) trends and intervention strategies in Florida. The fiscal, emotional, and health-related costs related to general obesity are staggering. Unfortunately, CO-related publicity, research, policy, and interventions have not been entirely successful in addressing the problem. Florida ranks 35thnationally in prevalence of CO. Data from the Centers for Disease Control and Prevention (CDC) 2013 report a statistically significant decrease in Florida\u27s rate of CO among 2-4 year-olds participating in Florida’s Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) from 2008-2011. Whereas Florida still has significant room for improvement on the issue of CO, its relatively low CO prevalence indicates a step in the right direction. Information provided herein provides valuable insight, resource information, and motivation to healthcare providers, particularly registered dietitian nutritionists (RDNs). As nutrition experts employed in various areas of society, RDNs are advantageously situated to contribute significantly to the CO solution. Florida appears to benefit from interdisciplinary collaborations among healthcare facilities, schools, faith-based organizations, governmental agencies, and grassroots programs that may play a major role in the current fight against CO

The translation of articles from the United Nations Convention on the Rights of the Child into education legislation:the narrowing of Article 12 as a consequence of translation

This paper is concerned with the inclusion, exclusion and reshaping of articles within the United Nations Convention on the Rights of the Child (CRC) as they are translated into English education legislation. The CRC comprises 54 articles aimed at outlining rights and freedoms for children and was ratified by the United Kingdom (UK) government in 1991. The paper builds on a previous publication by the authors which highlighted how the mobilisation of articles within the CRC into professional practice undergoes multiple translations. This paper takes an in‐depth and critical look at the first stage of the translation process in which articles are mobilised from the CRC into national legislation. Specifically, the paper presents findings from a documentary analysis which explored the translation of principles pertaining to Article 12 of the CRC into English Education Regulations, Acts and Statutory Guidance for schools. Findings demonstrate that the reshaping of the article within education legislation strongly reflects the government's priorities and agendas. The study raises new insights into the need to establish processes to ensure the full mobilisation of Article 12 and questions whether specific principles pertaining to the article could or should be incorporated into national legislative systems.Output Status: Forthcoming/Available Onlin

Vascular endothelial growth factor expression is independent of hypoxia in human malignant glioma spheroids and tumours

We recently showed that severe hypoxia was not universally present adjacent to necrosis in human glioma xenografts and spheroids established from the M059K, M006, M006X, M006XLo and M010b cell lines. Using these glioma models, we wished to test whether oxygen serves as a regulator of cellular VEGF expression in situ. In situ hybridization (ISH) and immunohistochemistry (IHC) were used to detect vascular endothelial growth factor (VEGF) mRNA and protein expression in sections of glioma xenografts and spheroids in which hypoxic regions and regions with well-oxygenated necrosis were identified on contiguous sections by use of the hypoxia-specific marker,3H-misonidazole. Independent validation of the presence of radiobiologically hypoxic cells in M006 xenografts was undertaken using the comet assay. Northern blotting analyses of monolayer cells demonstrated significant up-regulation of VEGF mRNA in the M006X line at oxygen concentrations of 6% and below. ISH analysis of VEGF mRNA showed unexpectedly strong staining for VEGF mRNA across the entire viable rim of M006X and M006XLo glioma spheroids. Similarly, in virtually all xenograft tumours of the M059K, M006 and M010b lines, VEGF ISH showed similar staining across all regions of healthy cells up to the border of necrosis. Only in one M006X tumour was there a suggestion of increased VEGF expression in cells adjacent to necrosis. IHC for VEGF showed good concordance with the ISH results. IHC analysis of the VEGF receptor flt-1 showed strong tumour cell staining in M006XLo glioma cells. In human glioma spheroids and xenograft tumours, regions of severe hypoxia do not correspond to areas of up-regulated VEGF expression; in fact, VEGF expression is quite uniform. Furthermore, this and our previous study demonstrate that levels of VEGF expression vary among sublines (M006, M006X and M006XLo) derived from a single human glioma specimen. © 2000 Cancer Research Campaig
