Abstract: Staphylococcus aureus is responsible for numerous food poisonings due to the production of enterotoxins by strains contaminating foodstuffs, especially dairy products. Several parameters, including interaction with antagonistic flora such as Lactococcus lactis , a lactic acid bacterium widely used in the dairy industry, can modulate S. aureus proliferation and virulence expression. We developed a dedicated S. aureus microarray to investigate the effect of L. lactis on staphylococcal gene expression in mixed cultures. This microarray was used to establish the transcriptomic profile of S. aureus in mixed cultures with L. lactis in a chemically defined medium held at a constant pH (6.6). Under these conditions, L. lactis hardly affected S. aureus growth. The expression of most genes involved in the cellular machinery, carbohydrate and nitrogen metabolism, and stress responses was only slightly modulated: a short time lag in mixed compared to pure cultures was observed. Interestingly, the induction of several virulence factors and regulators, including the agr locus, sarA , and some enterotoxins, was strongly affected. This work clearly underlines the complexity of L. lactis antagonistic potential for S. aureus and yields promising leads for investigations into nonantibiotic biocontrol of this major pathogen.

Abstract: There have been relatively few attempts to construct local housing market models in the United Kingdom—particularly models with an explicit treatment of land supply. In this paper we report the results of a pilot study designed to test the practicability of estimating a system of equations which describe housing market dynamics at the local level. Former district council areas in Central Scotland are used as a proxy for local housing markets within a region, thereby providing a panel dataset. A simple supply — demand system with separate equations for inward and outward household migration is modelled using two-stage least squares. The empirical results are varied, with some equations and coefficients performing more closely in line with prior expectations than others. House price levels are explained largely with reference to household income, socioeconomic status, and past levels of house price growth. Higher price levels and higher deprivation diminish inward migration. There are also suggestions in the results that higher rates of new-build supply partly cause higher inward migration. The rate of outward migration increases with ethnicity and wealth and decreases with deprivation. The empirical performance of the new-build supply equation is poor although the results do yield some interesting insights. House building output generally decreases as the proportion of ‘small’ sites in the land supply increases. There is also evidence that house building output decreases as land supply in neighbouring areas increases. We conclude the paper by outlining further directions for modelling prices, supply, and migration at local housing market level. In particular, the case is made for further work involving the collection of wider and longer panel datasets and for extending the pilot study work beyond Scotland.

Abstract: The article contributes to debate on the future of the council tax by focusing on the revaluation of council tax bands. Originally, no revaluations were foreseen and as yet none has occurred in Britain. The article argues there is a strong equity argument for frequent revaluations. An assessment of the potential impact of a revaluation is undertaken for a s le area of 11 local authority areas in Scotland. This research finds that, while addressing the equity issue, a revaluation is likely to create more disruption to local government, personal finances and the housing market than revaluations within a capital value-based tax system.

Abstract: Energy saving measures, if incorporated into existing and new buildings, can help the UK to achieve its ambitious goal to reduce carbon emissions by 80 per cent by 2050. Yet, the penetration of such technologies has been slow in the commercial real estate market. This paper examines the attitudes and preferences of office end users and their acceptance of carbon emission reducing technologies. It employs conjoint analysis to model the real estate decision-making of 150 respondents who claimed to have an input into their organisation’s choice of premises. The findings demonstrate that functionality and accessibility remain top priorities in occupiers’ choice of premises. Lower rents, improved corporate image and productivity are revealed as attributes that could compensate occupiers for energy-efficient attributes that restrict control over internal environment and operation of equipment. The paper discusses instruments to promote greater acceptance and penetration of carbon emission reducing design features in the office market.

Abstract: Arguments about sustainable urban form have generally been in normative terms without recourse to its practicality. The paper shows that the essential elements of urban form are outcomes of real estate markets. The focus of the research is to examine the economic sustainability constraints to the adaptation of the existing urban form via housing market development viability. To address the task a number of econometric models are linked together to estimate spatial patterns of viability in five cities. The results demonstrate a substantial difference between cities that can be attributed not to urban form per se but to socioeconomic factors. This demonstrates that in practice it is impossible to orce the physical structure of cities from their economic and social structure. Viability is also influenced strongly by public policy through the location of social housing. The research suggests that a driving force/constraint for development viability is the level of neighbourhood house prices. Large swathes of negative viability are found even without accounting for the additional costs of brownfield development, suggesting that there are major constraints to the reconfiguration of housing markets in some cities in a piecemeal way.

Abstract: Economic research on UK housing markets has only recently got to grips with measuring and modelling the impact of planning and other public interventions, although their importance has long been recognised in theory. The interurban panel dataset utilised in this study does represent a step forward, by permitting more robust econometric estimation and by incorporating a wider, more balanced range of determinant factors. A coherent set of relationships governing the key market outcomes-house prices, new building, migration and vacancies-can be established. The modelling framework is used to explore differences in behavioural responses between markets in 'high' and 'low' demand states. Simulations are used to track the impact on market outcomes of different policy strategies applied in different types of locality. Supply measures needed to achieve national targets for house price growth reduction are assessed. Measures acting on both demand-side and supply-side variables in areas of high and low demand are compared. These suggest that output is more sensitive than price to policies and that quite strong, concerted policies would be needed to impact significantly on the major market imbalances currently seen.

Abstract: A major unproven hypothesis in housing economics is that regional ripple effects are caused by household migration between regions. This paper examines household migration and price ripples at the level of local housing markets driven partly by the fact that such migration linkages are likely to be more pronounced between local, rather than regional, housing markets. Following a review of regional housing market studies, several hypotheses linking the existence of lead-lag relationships and cointegration with the scale of migratory linkages between local housing market areas (LHMAs) are proposed. Using private housing transactions data for Strathclyde, a sub-region of Scotland, the paper identifies two clusters of LHMAs that differ in terms of their migratory linkages with Glasgow, the hypothesised leading housing market of the sub-region. Tests for lead-lag relationships and cointegration confirm the link between migration and house price changes.
