Evaluating the use of an urban consolidation centre and electric vehicles in central London

The paper focuses on the role that can be played by urban consolidation centres (UCCs) in reducing freight traffic and its environmental impacts in towns and cities. It is based on the before and after evaluation of a trial led by a major stationery and office supplies company in which urban freight deliveries in central London made from a depot in the suburbs using diesel vehicles were replaced with the use of an urban micro-consolidation centre located in the delivery area together with the use of electrically-assisted cargo tricycles and electric vans. The results show that the total distance travelled and the CO2eq emissions per parcel delivered fell by 20% and 54% respectively as a result of this delivery system. However, the evaluation has also indicated that the distance travelled per parcel rose substantially in the City of London delivery area as a result of the electric vehicles having far smaller load limits in both weight and volume compared with diesel vans. But, at the same time, the trial system was able to virtually eliminate CO2eq emissions per parcel delivered in the City of London. The trial proved successful from the company's perspective in transport, environmental and financial terms. The company therefore decided to continue the operation beyond the end of the trial with it being officially launched during 2010.

In vitro study of the effect of wound dressings on planktonic and biofilms from diabetic foot isolates

The management of wound bioburden has previously been evaluated using various antimicrobial wound dressings on bacterial pathogens isolated from various wounds. In this present study, the antimicrobial effect of silver-impregnated dressings (Acticoat and Silvercel) and honey-impregnated dressing (Medihoney™ Apinate) on both planktonic bacteria and quasi-biofilms by Staphylococcus aureus and Proteus mirabilis were assessed using a 6-well plate and standard agar technique. In the 6-well plate assay, a bacterial suspension of 108 colony forming unit (CFU)/mL was inoculated on each dressing in excess Luria-Bertani broth and incubated at 35 – 37°C for 30 and 60 minutes and 24 hours. After each incubation time, bacteria were recovered in sodium thioglycolate solution (STS) and the CFU/mL determined on LB agar. Dressings were cut into circular shapes (2cm diameter and placed on Mueller Hinton agar plates pre-inoculated with bacterial suspensions to determine their zones of inhibition (ZOI) after 24 hours incubation. None of the dressings was effective to significantly inhibit bacterial growth or biofilm formation at all the times tested. Acticoat and Medihoney™ Apinate produced ZOIs between 1.5 – 15 mm against both Staphylococcus aureus and Proteus mirabilis. It is possible that, dressings augmented with antibiotics can significantly reduce quasi-biofilms on standard agar.

The Big Society and the conjunction of crises: Justifying welfare reform and undermining social housing

This article considers the idea of the ‘Big Society’ as part of a long-standing debate about the regulation of housing. Situating the concept within governance theory, the article considers how the idea of the Big Society was used by the UK coalition government to justify a radical restructuring of welfare provision. The fundamental rationale for this transformation was that the UK was forced to respond to a conjunction of crises in morality, the state, ideology and economics. Representing a fundamental departure from earlier attempts at welfare reform, the government has undertaken a reform programme which has had a severe effect on the social housing sector. The article argues that the result has been a combination of libertarianism and authoritarianism, alongside an intentionally more destructive combination of stigmatization and fatalism. The consequence is to undermine the principle of social housing which will not only prove detrimental for residents but raises significant dilemmas for those working in the housing sector.

Parallel languages in the history of language ideology in Norway and the lesson for Nordic higher education

This chapter compares recent policy on the use of English and Norwegian in Higher Education with earlier policies on the relationship between the two standard varieties of Norwegian, and it charts how and why English became a policy issue in Norway. Based on the experience of over a century of language planning, a highly interventionist approach is today being avoided and language policies in the universities of Norway seek to nurture a situation where English and Norwegian may be used productively side-by-side. However, there remain serious practical challenges to be overcome. This paper also builds on a previous analysis (Linn 2010b) of the metalanguage of Nordic language policy and seeks to clarify the use of the term ‘parallelingualism’.
