The theory of the firm is employed to explain behaviour of the church. Churches produce a set of products including entertainment, a variety of socially valuable public goods, eternal life and alteration of otherwise fated events. Most importantly, it reduces transactions costs by enforcing a system of property rights. Enforcement is enhanced by the promise of heaven and threat of hell, two innovations uniquely available to the church. Some implications of the model using the standard Cross‐cultural Sample of the Human Relations Area Files are tested.

It has often been said that a great part of the strength of Aslib lies in the fact that it brings together those whose experience has been gained in many widely differing fields but who have a common interest in the means by which information may be collected and disseminated to the greatest advantage. Lists of its members have, therefore, a more than ordinary value since they present, in miniature, a cross‐section of institutions and individuals who share this special interest.

This article explores the cultural politics of civic pride through Hull's year as UK City of Culture (UKCoC) in 2017. It unpicks some of the socio-political meanings and values of civic pride in Hull and critiques the ways in which pride, as an indicator of identity and belonging, was mobilised by UKCoC organisers, funders and city leaders. It argues for more nuanced and critical approaches to the consideration and evaluation of pride through cultural mega events (CMEs) that can take account of pride's multiple forms, meanings and temporalities.

A multidimensional, mixed methods approach is taken, incorporating the critical analysis of Hull2017 promotional materials and events and original interviews with a range of stakeholders.

The desire for socio-economic change and renewed identity has dominated Hull's post-industrial sense of self and is often expressed through the language of pride. This article argues that UKCoC organisers, cognisant of this, crafted and tightly controlled a singular pride narrative to create the feeling of change and legitimise the entrepreneurial re-branding of the city. At the same time, UKCoC organisers overlooked the opportunity to engage with and potentially reactivate the political culture of Hull, which like other “left behind” or “structurally disadvantaged” places, is becoming increasingly anti-political.

Through the case study of a relatively unresearched and under-represented city, this paper contributes to cultural policy literatures concerned with critically assessing the benefits and shortcomings of Cultural Mega Events and to a more specific field concerning Cities of Culture and the political cultures of their host cities. This paper also contributes to an emerging literature on the centrality of pride through the UK's post-Brexit Levelling Up agenda, suggesting that pride in place is becoming figured as a “universal theme” of the neoliberal city script.

Since their creation through the Industrial Training Act 1964 to hear appeals against levies, the jurisdiction of industrial tribunals has grown considerably. One aspect of this jurisdiction, unfair dismissal, is examined here. Basic principles related to the law of unfair dismissal are examined. The practice and procedure of an industrial tribunal solely in connection with unfair dismissal cases are examined in greater detail. A case study is used to illustrate the important aspects of procedure. Appendices give relevant forms and extracts from the appropriate Code of Practice.

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.

Problems of competence grow out of institutional culture and from the way these institutions shape the profession and its members. Toward that end, this chapter is organized around three general considerations. First, we discuss some general issues about leader quality. Second, the present shape of the leadership corps in higher education will be discussed. Finally, we introduce several 21st century leadership core competencies (Brooks & Normore, 2009) for consideration to hiring personnel so they do not repeatedly select and promote unqualified leaders who stifle creativity and encourage conformity.

The purpose of this study is to review and summarise the existing available literature on lightweight cladding systems to provide detailed information on fire behaviour (ignitibility, heat release rate and smoke toxicity) and various test method protocols. Additionally, the paper discusses the challenges and provides updated knowledge and recommendation on selective-fire mechanisms such as rapid-fire spread, air cavity and fire re-entry behaviours due to dripping and melting of lightweight composite claddings.

A comprehensive literature review on fire behaviour, fire hazard and testing methods of lightweight composite claddings has been conducted in this research. In summarising all possible fire hazards, particular attention is given to the potential impact of toxicity of lightweight cladding fires. In addition, various criteria for fire performance evaluation of lightweight composite claddings are also highlighted. These evaluations are generally categorised as small-, intermediate- and large-scale test methods.

The major challenges of lightweight claddings are rapid fire spread, smoke production and toxicity and inconsistency in fire testing.

The review highlights the current challenges in cladding fire, smoke toxicity, testing system and regulation to provide some research recommendations to address the identified challenges.

Heat treatment, in view of later knowledge, is seen to have other effects than to destroy or lower the vitality of micro‐organisms initially present; there are the more obvious changes of flavour and of consistency brought about by the partial cooking, but there are also the possible lowering of the vitamin potency and the still more subtle changes in the salts which may, after heat treatment, be rendered less available than in the raw product. The importance of these considerations cannot be too much stressed when it is remembered that heat treatment is, generally speaking, an inherent stage in the process of canning. It is the heat treatment which preserves the goods, the sealing of the can being merely a means of prevent re‐contamination. The chemist, no less than the physiologist, has been much concerned with the changes in foods caused by heat treatment as a method of preservation, and, as a result of his investigation, there is now a better understanding of the changes which take place, with a consequent improvement in the methods of processing. For a number of years, however, this country, in common with many others, has relied, in so far as its supplies of meat are concerned, on products preserved by “cold,” and the freezing of beef, the chilling of mutton, have made available to us the cattle of the Argentine and the sheep of New Zealand. Initially the processes employed were crude, the post‐mortem changes were imperfectly understood, conditions of storage, before, during and after shipment, were haphazard, and the methods of defrosting far from scientific. How far the methods have advanced, and to what extent the scientist has been concerned in the elucidation of the many problems, will be realised from the reports of the Food Investigation Board. It is not suggested that all the advance is due to the work of the Low Temperature Station a Cambridge—much has been done in other countries‐but the investigations carried out by the scientists a this station have been fundamental. Food producers in America were the first to realise the importance of the latest development in freezing, the advent of the “ Quick Freezing Processes ” marking a distinct advance in technique. When cellular tissue is normally frozen and subsequently defrosted, rupture of the cells may have occurred and the structure of the substance consequently partially broken down. When, however, the tissue is quickly brought down to a very low temperature, it is found that in many cases this breakdown in tissue does not take place. These principles have been applied to commercial installations, and fish, meat, fruit and vegetables so treated show on defrosting remarkably little change in character. Preservation by desiccation is a method employed for certain materials with great success. Sun‐drying of fruits (sultanas and dates, to quote but two) and the sun‐drying of cereal products such as macaroni is still practised. An important industry concerned with the drying of milk has developed in most milk‐producing countries, whilst dried eggs and dried egg‐albumin form important items of commerce. It is obvious that the object of concentrating such substances as fruit juices, milk and vegetables and animal liquid extracts is ideally to reduce the water content and obtain a product which, when the water is ultimately restored, gives a solution or material having the original taste, aroma and food value. The effect of heat is often, however, to change these characteristics, and although by the use of a vacuum the temperature to which the substance is submitted is lowered, changes still take place, and much of the aroma depending on volatile constituents is lost. To a very great extent this has been overcome by a method of desiccation which is essentially partial freezing, a method which has not yet received much publicity as it has only lately emerged from the experimental stage. The practical application of this principle is due to Dr. G. A. Krause, of Munich, who has invented and designed a dual process of concentration. In this process the liquid is first concentrated by freezing out water as ice, which is removed by mechanical separation in a centrifuge. By ingenious mechanical and regenerative devices this process has been made extremely efficient, the losses being only 1–2 per cent. of the original juice, although the efficiency is not maintained when the solids‐content of the product has been raised to 40–50 per cent. This liquid is then further concentrated by evaporation at a low temperature, about 10°–15° C. The differential evaporation of water as compared with the aromatic flavour constituents occurs because the removal of water as vapour at this temperature depends solely on the rate of diffusion of the molecules into the gas space. As water has a small molecule compared with the large molecules of the esters, ethers and alcohols of the flavouring substances, it escapes more readily ; the conditions of evaporation as given in the patent are all designed to aid this escape. A reduction in pressure may be used to speed up the process without interfering with the differential diffusion, and the provision of an atmosphere of small molecules (e.g., hydrogen) also has the same effect. A large surface for the evaporation is made by spreading the liquid as a thin continuously renewed film. The condenser is situated very near the evaporating liquid to remove the water molecules quickly (a distance of 3 cm. is the maximum diffusion path). The atmosphere may be circulated or disturbed to hasten the diffusion and, most ingenious of all, it may be blown towards the evaporating liquid when, if a velocity is used just greater than that of the heavy molecules leaving a liquid surface, the loss of flavour may be entirely eliminated while the rate of water evaporation is only reduced by 10 per cent. By these means a concentrate containing as much as 65 per cent. solids and capable of storage without deterioration at ordinary temperatures may be prepared, and 80 per cent. of the original vitamins retained. The use of refrigeration in the preservation of food has necessitated the use of refrigerated transport to complete the links between producer, manufacturer, retailer and customer. The variety of commodities and the different conditions they need create varying demands on the methods of insulating and refrigerating transport vehicles. The British railways have 4,000 refrigerated railway vans, and such vans, containing perishable produce, came regularly to England from Austria and Italy by way of the train ferries. These vans are designed for fairly high temperatures, 35–40° F., and long hauls, and use ice as a refrigerant. At the other end of the scale is the road vehicle, which may have a temperature as low as 0° F., but is only on its journey about 12 hours. It is in these road vehicles that the greatest advances have been made, for conditions in England do not justify the railways in expenditure on elaborate equipment. The early road vehicles were insulated boxes on a lorry chassis and were refrigerated by ice and salt, which was “messy” and caused bad corrosion of the chassis. The introduction of an eutectic solution, virtually a mixture of a freezing salt and water in a definite proportion, which was frozen as a whole in a sealed tank, was made some few years ago. This removed the “messiness,” conserved the salt and produced greater efficiency and a more stable temperature.
