In spite of microbiological Quality Assurance (QA), which has been employed for many years to guarantee the quality of food products in their early stages, food poisoning outbreaks are still increasing. Although food handlers must be educated still further in matters of hygiene, QA (on the microbiological analysis of food) should not be allowed to rest on its laurels, and its present limitations and possible improvements in its specifics and applications are treated here.

The Hazard Analysis and Critical Control Point (HACCP) system is superior to end product testing because it predicts potential problems and specifies control systems to prevent them occurring. Another advantage is that control, by features that are fast, cheap and easy to monitor, is focused at the critical points in the operation. Further, HACCP is a team approach that involves all members of staff in food safety. HACCP can be used in almost any situation. An ad hoc working group of the Codex Alimentarius Food Hygiene Committee recently produced a draft agreement on the principles of HACCP and their application to food operations. Included in this is a logic‐based decision tree for the determination of Critical Control Points.

The work set out to design and develop an overheating risk tool using the UKCP09 climate projections that is compatible with building performance simulation software. The aim of the tool is to exploit the Weather Generator and give a reasonably accurate assessment of a building's performance in future climates, without adding significant time, cost or complexity to the design team's work.

Because simulating every possible future climate is impracticable, the approach adopted was to use principal component analysis to give a statistically rigorous simplification of the climate projections. The perceptions and requirements of potential users were assessed through surveys, interviews and focus groups.

It is possible to convert a single dynamic simulation output into many hundreds of simulation results at hourly resolution for equally probable climates, giving a population of outcomes for the performance of a specific building in a future climate, thus helping the user choose adaptations that might reduce the risk of overheating. The tool outputs can be delivered as a probabilistic overheating curve and feed into a risk management matrix. Professionals recognized the need to quantify overheating risk, particularly for non‐domestic buildings, and were concerned about the ease of incorporating the UKCP09 projections into this process. The new tool has the potential to meet these concerns.

The paper is the first attempt to link UKCP09 climate projections and building performance simulation software in this way and the work offers the potential for design practitioners to use the tool to quickly assess the risk of overheating in their designs and adapt them accordingly.

Traditional microbiological methods to monitor the growth or survival of microbes are very labour‐intensive and rather expensive and the knowledge acquired is not cumulative. Predictive microbiology as an alternative approach has been developed utilizing mathematical models to predict the microbial inactivation, survival or growth during food processing. The purpose of this paper is to review the evolutions and limitations of primary mathematical models in predictive microbiology.

Primary models deal with the variation of microbial populations against time under particular environmental and cultural conditions. According to the behaviour of micro organisms during food processing and storage, primary models can be divided into inactivation/survival models and growth models. Literature is reviewed to assess the performance of these mathematical models.

In order to predict microbial survival or growth curves, some empirical mathematical models have been used. Most of them have no or little microbiological or physiological basis, which make the interpretation of some model parameters difficult and their performances do not match observed microbiological outcomes. To produce a more accurate mathematical model, more mechanisms are necessary to interpret model parameters with a biological basis.

The paper reviews the evolution and limitations of primary mathematical models, which may help future model development.

This paper describes supported employment, its growth as an alternative to traditional day services and research which indicates potentially beneficial outcomes in the areas of increased employee income, social integration, satisfaction, engagement in activity, employer satisfaction, and in the relationship between financial costs and savings. Outcomes may be reduced due to welfare benefit restrictions that hamper transition into employment, and more part‐time jobs are found as a result in the UK compared to the USA. Providers face problems with low expectations among carers, lack of knowledge of disability among employers, and their funding is precarious. If people with severe disabilities are not to be excluded from supported employment, commissioners need to consider the outcomes they require and the priority needs of clients when setting day service contracts.

This research looked at the TATE [Through Assistive Technology to Employment] Project and its delivery of ICT/AT to people with learning disabilities. It tested whether the Project affected the independence, skills, choice and control exercised by people with learning disabilities, and if staff attitudes and skills were changed. A purposive sample of 29 people with learning disabilities were selected, and keyworkers were surveyed with a postal questionnaire at two time periods. Questionnaires covered AT/ICT received and any outcomes in: independence; skills; choice and control. Staff were asked about changes in their skills and attitudes. Questionnaires were transcribed and organised into common themes. Staff became supportive of assistive technology and developed ICT skills. Service users used ICT, and developed ‘life stories’ using Powerpoint. A variety of AT was also installed leading to increased independence, confidence and skills. AT/ICT can improve independence and services by putting people with a learning disability at the centre of a well planned and resourced strategy.

This article focuses on the development and current situation of services for people with learning disabilities in England. Deinstitutionalisation started in the 1960s, when a series of scandals in hospitals were brought to public attention. In response, the 1971 government White Paper Better Services for the Mentally Handicapped was published, and the first community‐based services were introduced. Further policy papers attempted to modernise social services in the following period. The 2001 White paper Valuing People is the most recent policy framework specific to people with intellectual disabilities. It identifies rights, independence, choice and inclusion as the four leading principles for services and support, and will be of primary importance for future development. However, at present implementation is in the very early stages. Not least, the intense implementation of market mechanisms by the Thatcher Government in the 1980s and 1990s has led to a situation that is hard to grasp, the organisation of care and support varying from authority to authority.

This paper describes the piloting of an approach to social services inspection using a range of objective research evidence as part of the Social Services Inspectorate's inspection process in 1997, in eight local authorities in England. The Welsh Centre for Learning Disabilities Applied Research Unit worked with the Social Services Inspectorate to collect details on residential and day services in advance of the inspection process. The paper repeats the findings of this Report and of the collaboration.

That there has been a flood of this type of case in recent years—a flood which shows no signs of abating —must be manifest to all. In a paper “Food Sampling: Changing Trends” presented to a Sessional Meeting of the Royal Society of Health last March, Dr. H. Amphlett Williams, public analyst, tabulated a comparison of prosecutions in England and Wales reported in this Journal for five years before the War (1936–40) with five years since (1956–60). This showed that in the first period, “foreign body” cases were non‐existent compared with 37 per cent of total cases reported in the second period. It also showed that cases concerned with adulteration were 39 per cent of the total and milks, in particular, 41 per cent compared with 12 and 16 per cent respectively for the post‐war period.
