Turning around the poorest neighbourhoods: learning the lessons from twenty years of neighbourhood-based regeneration strategies in England

In the past two decades governments in Britain have launched a series of initiatives designed to reduce the disparities between areas of affluence and deprivation. These initiatives were funded by central government and were delivered through a series of partnership boards operating at the neighbourhood level in areas with high levels of deprivation. Drawing on similar approaches in the US War on Poverty, the engagement of residents in the planning and delivery of projects was a major priority. This chapter draws on the national evaluations of three of these programmes in England: the Single Regeneration Budget, the New Deal for Communities and the Neighbourhood Management Pathfinders. The chapter begins by identifying the common characteristics of these programmes, known as area-based initiatives because they targeted areas of concentrated deprivation with a population of about 10,000 people each. It then goes on to discuss the three national programmes and summarises the main findings in relation to how far key indicators changed for the better. The final section sets out the ways in which policy objectives changed in 2010 after the election of a coalition government. This produced a shift to what was called the ‘Big Society’ where the rhetoric favoured a transfer of power away from central government towards the local, neighbourhood, level. This approach favoured self-help and a call to volunteering rather than channelling resources to the areas in greatest need. The chapter closes by reviewing the relatively modest achievements of this centralist, big-state approach to distressed neighbourhoods of 1990–2010.

Entangled semantics

In the context of monolingual and bilingual retrieval, Simple Knowledge Organisation System (SKOS) datasets can play a dual role as knowledge bases for semantic annotations and as language-independent resources for translation. With no existing track of formal evaluations of these aspects for datasets in SKOS format, we describe a case study on the usage of the Thesaurus for the Social Sciences in SKOS format for a retrieval setup based on the CLEF 2004-2006 Domain-Specific Track topics, documents and relevance assessments. Results showed a mixed picture with significant system-level improvements in terms of mean average precision in the bilingual runs. Our experiments set a new and improved baseline for using SKOS-based datasets with the GIRT collection and are an example of component-based evaluation.

Sustainable Chemical Regulation in a Global Environment

The globalisation and unintended impacts of chemicals sets substantial challenges for sustainable development and the protection of natural resources such as land and water. Currently, there are three key chemical Conventions, the Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and their Disposal which came into force in 1992, the 1993 Rotterdam Convention on Trade in Dangerous Chemicals and the Stockholm Convention on Persistent Organic Pollutants (POPs) (2004). These Conventions have as common features a mechanism for assessment of chemical safety, a process for the addition of new chemicals to a list of controlled substances and capacity building in developed countries. However, they only cover a small fraction of the chemicals manufactured and traded across the world. Defining effective regulation of chemicals is an on-going debate that has the potential to have a significant impact on vested commercial and political interests. A sustainable chemical industry should take account of evidence-based standards and through legal mechanisms adopt long-term precautionary evaluations rather than short-term market driven decisions. It is argued in this paper that effective international chemical regulation in the future will come from the adoption of sound chemical management and corporate social responsibility, but it recognised that this will face the challenge of economic disparity between countries and the potential export of regulatory risk from big chemical conglomerates to poorly regulated jurisdictions.

A influência da marcha com tripé nos parâmetros metabólicos em jovens e idosos

Introdução: Os parâmetros metabólicos durante a marcha normal e a sua regulação são importantes devido ao metabolismo oxidativo ser o principal meio através do qual o organismo humano gera energia para realizar as atividades do quotidiano. Nem sempre a marcha é realizada de forma independente e necessita do apoio de auxiliares de marcha, como o tripé, que tem por função ampliar a base de sustentação e melhorar o equilíbrio. Objetivo: Analisar a influência de utilização de um tripé na marcha, na despesa energética em jovens e idosos saudáveis Métodos: Realizou-se um estudo observacional transversal numa amostra de 21 voluntários, com idade entre 18 a 25 anos e mais ou igual a 60 anos. Realizaram-se as avaliações com o Cosmed K4b2 (Cosmed, Rome, Italy), sendo através do mesmo que os dados foram recolhidos. Foi utilizado o teste de Friedman, com P <0,05. Resultados: Os resultados obtidos para o gasto energético nos jovens foram inferiores aos valores obtidos pelos idosos. Relativamente ao metabolismo energético o substrato energético utilizado pelos jovens foi o proteico e o lipídico pelos idosos. Entre sexos foram os homens quem tiveram um maior gasto energético. Conclusão: O uso do tripé durante a marcha não influencia o gasto energético em adultos jovens e/ou idosos saudáveis.

Biomimetic norfloxacin sensors made of molecularly-imprinted materials for potentiometric transduction

A biomimetic sensor for norfloxacin is presented that is based on host-guest interactions and potentiometric transduction. The artificial host was imprinted into polymers made from methacrylic acid and/or 2-vinyl pyridine. The resulting particles were entrapped in a plasticized poly(vinyl chloride) (PVC) matrix. The sensors exhibit near-Nernstian response in steady state evaluations, and detection limits range from 0.40 to 1.0 μgmL−1, respectively, and are independent of pH values at between 2 and 6, and 8 and 11, respectively. Good selectivity was observed over several potential interferents. In flowing media, the sensors exhibit fast response, a sensitivity of 68.2 mV per decade, a linear range from 79 μM to 2.5 mM, a detection limit of 20 μgmL−1, and a stable baseline. The sensors were successfully applied to field monitoring of norfloxacin in fish samples, biological samples, and pharmaceutical products

Ciprofloxacin-imprinted polymeric receptors as ionophores for potentiometric transduction

A 3D-mirror synthetic receptor for ciprofloxacin host–guest interactions and potentiometric transduction is presented. The host cavity was shaped on a polymeric surface assembled with methacrylic acid or 2-vinyl pyridine monomers by radical polymerization. Molecularly imprinted particles were dispersed in 2-nitrophenyl octyl ether and entrapped in a poly(vinyl chloride) matrix. The sensors exhibited a near-Nernstian response in steady state evaluations. Slopes and detection limits ranged from 26.8 to 50.0mVdecade−1 and 1.0×10−5 to 2.7×10−5 mol L−1, respectively. Good selectivity was observed for trimethoprim, enrofloxacin, tetracycline, cysteine, galactose, hydroxylamine, creatinine, ammonium chloride, sucrose, glucose, sulphamerazine and sulfadiazine. The sensors were successfully applied to the determination of ciprofloxacin concentrations in fish and in pharmaceuticals. The method presented offered the advantages of simplicity, accuracy, applicability to colored and turbid samples and automation feasibility, as well as confirming the use of molecularly imprinted polymers as ionophores for organic ion recognition in potentiometric transduction.

Por fim, será realizada uma reflexão crítica do desempenho como docente de saxofone no âmbito do estágio e uma conclusão de toda a seção da prática pedagógica.

Coordinated runtime adaptations in cooperative open real-time systems

This paper proposes an one-step decentralised coordination model based on an effective feedback mechanism to reduce the complexity of the needed interactions among interdependent nodes of a cooperative distributed system until a collective adaptation behaviour is determined. Positive feedback is used to reinforce the selection of the new desired global service solution, while negative feedback discourages nodes to act in a greedy fashion as this adversely impacts on the provided service levels at neighbouring nodes. The reduced complexity and overhead of the proposed decentralised coordination model are validated through extensive evaluations.

Design and evaluation of multi-band RF energy harvesting circuits and antennas for WSNs

Radio frequency (RF) energy harvesting is an emerging technology that will enable to drive the next generation of wireless sensor networks (WSNs) without the need of using batteries. In this paper, we present RF energy harvesting circuits specifically developed for GSM bands (900/1800) and a wearable dual-band antenna suitable for possible implementation within clothes for body worn applications. Besides, we address the development and experimental characterization of three different prototypes of a five-stage Dickson voltage multiplier (with match impedance circuit) responsible for harvesting the RF energy. Different printed circuit board (PCB) fabrication techniques to produce the prototypes result in different values of conversion efficiency. Therefore, we conclude that if the PCB fabrication is achieved by means of a rigorous control in the photo-positive method and chemical bath procedure applied to the PCB it allows for attaining better values for the conversion efficiency. All three prototypes (1, 2 and 3) can power supply the IRIS sensor node for RF received powers of -4 dBm, -6 dBm and -5 dBm, and conversion efficiencies of 20, 32 and 26%, respectively. © 2014 IEEE.

Influence of grease rheology on thrust ball bearings friction torque

The friction torque and the operating temperatures in a thrust ball bearing were measured for seven different types of greases, including three biodegradable greases having low toxicity. These friction torque tests were performed using a modified Four-Ball machine. Rheological evaluations of the lubricating greases were made using a rheometer. Bleed oils were extracted from the greases and the dynamic viscosities were measured. In order to compare the performance of the lubricant greases in terms of friction, the grease characteristics were related to experimental results, showing that the interaction between thickener and base oil have strong influences in the bearing friction torque.
