If it is a fraud to dye an unripe orange to make it look ripe, why should it be permissible to dye winter butter to make it look like summer butter?”, he says. Or one might add, to dye a biscuit brown to imply the presence of chocolate or to colour a cake yellow to simulate the addition of eggs? Our third heading is, What? What colouring matters should be allowed, and upon what conditions? Great Britain is the only leading country which has not a legal schedule of permitted colours. In this country any colouring agent may be added to food, except compounds of antimony, arsenic, cadmium, chromium, copper, mercury, lead and zinc. Gamboge, picric acid, victoria yellow, manchester yellow, aurantia and aurine are also prohibited. The addition, however, of any other colouring agent which is injurious to health would be an offence under the Food and Drugs Act. Other countries, including the United States of America, France, Canada, Australia, New Zealand, Italy, Spain, Sweden and Denmark have drawn up lists of permissible colours. And so the question arises—is it preferable to draw up a list of permissible colours or one of prohibited colours? It is obvious that if only certain colours are prohibited the remainder may be legally employed so long as they are not injurious to health. Thus a colouring agent may be used for a considerable time before it is proved to be injurious, whereas, if only‐certain colouring agents which have been previously proved to be non‐injurious were permitted, this risk of possible danger to health would be avoided. There is no doubt that in many cases proof of injury to the health of the human being is difficult to obtain. Much of the work that has been carried out to establish whether a particular dye is harmless or not has involved the use of dogs as test subjects. This does not appear to be a very satisfactory method of testing, for obviously dogs may react very differently from human beings towards chemicals. A dog's digestive powers are stronger than those of humans. No one would think of suggesting that bones are suitable food for humans just because dogs love them! Matta found that the capacity to depress the human digestion is possessed not only by poisonous dyes but also by dyes which he had proved to be non‐poisonous to animals. In bacteriology the addition of very small amounts of certain dyes to the culture medium will retard the growth of particular organisms and therefore it would seem possible that some dyes might adversely affect the action of enzymes in the body. So it would seem of importance that, if possible, all colouring matters, before being permitted to be used in food, should be proved by a competent authority to be harmless to human beings. If the effects of colouring matters upon the human digestive processes cannot be easily carried out in the body then it might be possible to perform such tests in vitro, using artificial gastric juice. It may be argued that the proportion of colouring matter added to food, ranging from about 1 part in 2,000 to about 1 part in 300,000, is so small that any particular colouring agent would need to be a deadly poison before any appreciable injurious effect upon health would occur. This argument does not, however, take into account the possible injurious effects which may be caused by the frequent ingestion of colouring matters which may have but mild toxic properties. It is known, for instance, that many synthetic colours have marked antiseptic properties even in highly diluted solutions, and therefore they may adversely affect the digestive processes. In any case, surely it would be wiser to eliminate all risks by requiring that official physiological tests should be carried out upon colouring matters before they are permitted to be used in food. One has to safeguard not only the healthy person but also the very young, the old and those who are of a delicate constitution. A harmless colour has been defined in Canada as one “which will not retard digestion nor have special physiological effects when consumed in quantities corresponding to 2 grains per day per adult.” The Departmental Committee in its report on “The use of preservatives and colouring matters in food,” published in 1924, stated that “It appears to us that definite evidence from direct experiments should be obtained as to the harmlessness of a dye before its use should be permitted in food. We have therefore come to the conclusion that a list of permitted colours should be prepared and that no colours other than those in such a list should be allowed to be used in the preparation of food. The list should, in our opinion, be prepared by the Minister of Health and issued by him, provision being made for the consideration of claims advanced by traders for the recognition and approval of additional colours on satisfactory evidence of harmlessness. We do not think that action such as this should seriously embarrass manufacturing interests, or is a course on which it is unreasonable, in view of the importance of the subject, to insist.” Yet, in spite of these recommendations of the Committee, no list of permitted colours was passed into law, and one wonders why. One argument against the drawing up of a list of prohibited colours is that even if a non‐prohibited colour is proved to the satisfaction of a given Court to be injurious to health that decision is not binding on other Courts and so there may be a lack of uniformity. A certain colour may be permitted in one town and prohibited in the next, which fact might add to the difficulties of the large scale manufacturer whose products are sold over a wide area. The leading manufacturers of dyes for use in food no doubt exercise great care in their preparation and such products are normally free from objectionable impurities, but it is possible that other dyestuff manufacturers are not so particular concerning the purity of their products. For instance, about 1938 a firm was fined for selling “Damson Blue” containing 540 parts of lead per million. Therefore it would seem necessary that some official control over the dyes that are sold for use in food should be introduced. The manufacture of some dyes involves complicated processes, and it is stated that in the production of one particular colour over 100 different chemicals are used and thirty different reactions, occupying several weeks, must be carried out before the finished colour is produced.

The cost per loan for the manual circulation system at the University of Essex Library is calculated for 1970/71 and predicted for 1973/74 and 1976/77. An allowance is made for the time spent by library users when borrowing books. Likely costs for an on‐line circulation system are also calculated. A table is given for manual, off‐line and on‐line circulation systems costs for several university libraries.

In 1993, US Congress launched the Urban Revitalization Demonstration program, later to become known as HOPE VI, a national plan whose declared aim was to transform public housing stock into "bridges of opportunities".

In the following decade, Hope VI has awarded grants to demolish public housing projects and replace them with "attractive developments that not only blend with but enhance the surrounding community while providing housing for families of all incomes" (HUD, 1999). In 1995, Congress repealed the one-for-one replacement requirement and de facto Hope VI was turned primarily into a demolition program.

In 2003, the American Dream Downpayment Act re-authorised the Hope VI program throughout the fiscal year 2006. It now seems that the federal government has no intention to continue its financing.

Despite the extensive debate on the program, a comprehensive analysis of the social, economic and political process underlying the transformation of all the specific sites and a systematic overview of the stories behind these projects, from the first decision to build to the decision to raze are not available.

An atlas with a description of the sites, based on qualitative secondary sources (planning and architecture magazines, urban history and geographic history journals, local authorities reports), and three maps for each of them - before and after the public housing project and after Hope VI, could prove to be very useful. Such a tool would indeed provide the context for an interdisciplinary reflection of how the city affects and is affected by a multitude of variables with particular emphasis on the political controversies on location, and the role of different players - city council, public housing authorities, developers, community residents, unions, the media. At the end, city is "history condensed".

Being impossible for a single researcher to complete such a body of work, this paper intends to make a contribution to the existing literature and focus on the projects built between 1933 and 1949, now demolished or in the way to be demolished in 58 cities, "thanks" to Hope VI (1).

The World Wide Web (WWW) offers exciting new opportunities for small and medium‐sized enterprises (SMEs) to extend their customer base into the global marketplace. However, in order to exploit these advantages in a global strategy, the SME needs to adopt an entirely different approach to strategic planning and management which can enable it to deploy an extensive infrastructure network based on shared resources with other firms. This paper presents a framework for the analysis and design of global strategies within the organisational context of SMEs using Internet‐based information technologies. Central to the framework – SMALL – is the transformation of the key attributes of an SME environment through a virtual organising perspective. The framework is supported by a number of case examples of SMEs operating in a global context and a detailed analysis of three Australian SMEs. It provides a new perspective to strategies for e‐business in SMEs and to e‐business research.

The purpose of this paper is to explore theoretical connections between educational leadership for social justice and support for immigration. The authors seek to identify strengths, weaknesses and opportunities for further study and improved practice.

This is a theoretical research paper that introduces, evaluates and expands two frameworks for understanding leadership and immigration.

Findings suggested that there is a need for educational leadership scholars to more purposefully investigate issues related to social justice and immigration.

This study offers a novel theoretical perspective on leadership, social justice and immigration.

This review paper will look at internationally existing publications in the English language on mental health shared decision making (SDM) implementation of a variety of interventions, including different methodologies and research methods, age groups and countries. The purpose of this paper is to provide an overview of: process, degree and outcomes of implementation; barriers and facilitators; perspectives on implementation by different stakeholders; analysis of the process of implementation in mental health services through the lenses of the normalisation process theory (NPT).

Following a targeted literature search the data were analysed in order to provide an overview of methodologies and methods applied in the articles, as well as of the variables listed above. Three different types of information were included: a content analysis of key issues, reflective understanding coming out of participating in implementation of an SDM project in the form of two narratives written by two key participants in an SDM pilot project and an NPT analysis of the process of implementation.

Only a minority of mental health SDM research focuses on implementation in everyday practice. It is possible and often desirable to achieve SDM in mental health services; it requires a low level of technology, it can save time once routinized, and it is based on enhancing therapeutic alliance, as well as service users’ motivation. Implementation requires an explicit policy decision, a clear procedure, and regular adherence to the aims and methods of implementation by all participants. These necessary and sufficient conditions are rarely met, due to the different levels of commitment to SDM and its process by the different key stakeholders, as well as due to competing providers’ objectives and the time allocated to achieving them.

The review indicates both the need to take into account the complexity of SDM, as well as future strategies for enhancing its implementation in everyday mental health practice. Perhaps because applying SDM reflects a major cultural change in mental health practice, current value attached to SDM among clinicians and service managers would need to be more positive, prominent and enduring to enable a greater degree of implementation.

Previous literature has reported that working with sexual offenders can impact staff negatively (Hatcher and Noakes, 2010). In addition, working with individuals with intellectual disability also appears to be challenging. There are benefits stated of working with sexual offenders and the purpose of this paper is to seek to highlight the challenges and positive experiences of staff members working with sexual offenders who have autism.

As working with this population has not been previously investigated, a semi-structured interview was conducted to explore the challenges and benefits of working with this population. Eight participants were interviewed who work on the autism specialist ward at a forensic secure hospital in the UK.

Template analysis identified three master themes: mediating factors, challenges and consequences, which were incorporated into the Model of Person-Organisation Wellbeing (M-POW). The findings show the specific challenges of working with a population that has not been previously studied.

The study utilised a small, heterogeneous self-selecting sample from one clinical site.

Findings suggest there are a number of specific challenges this staff group face, and steps that can be taken at the personal and organisational level to mediate these. Recommendations are made for how staff are supported in their work from recruitment and induction onwards.

The M-POW highlights mediating factors that can be adjusted to develop more effective coping strategies for working in what, for some, is a challenging environment. This model provides a framework that can be adopted by organisations to ensure that the likelihood of their staff experiencing negative feelings is reduced and also suggests future avenues of research.
