Community-based randomised control trials (RCTs) rely heavily on the involvement and collaboration of statutory and third-sector services and their employees. This paper seeks to explore the experiences of practitioners working within a statutory children and family service setting that delivered additional parenting programmes evaluated by an RCT.

Practitioners completed a semi-structured interview about their experiences of the research trial based on a topic guide. Interviews were recorded, transcribed and analysed using thematic analysis.

Results suggest that the experience of being involved in research was mostly positive for practitioners, but also produced additional stress. The research brought them the experience of being involved with national and international teams; and they valued the additional supervision and training that they received. They spoke about the skills that they developed and how they were able to continue to use these after the research trial had ended.

Little is known about how services working alongside major research projects experience their involvement and what impact, if any, this has on them. This may be important as it could influence successful recruitment and retention of practitioners during RCTs, and the successful design and execution of other types of evaluation.

Within the past 20 years hiking and backpacking have enjoyed rapid growth among Americans as favorite outdoor activities. From 1965 to 1977 the number of hikers almost tripled, from 9.9 million to 28.1 million, while national forest visitor days among hikers and mountaineers increased from 4 million in 1966 to 11 million in 1979. Accompanying this growth in interest has been a boom in books about the sport. These include both “how‐to‐do‐it” volumes and guides to specific geographical areas. Each year brings another spate of books, yet to this compiler's knowledge no bibliography of hiking guides to the Rocky Mountains, one of North America's premier outdoor regions, has yet been attempted. This bibliography is an effort to correct that situation.

If I were a wealthy man there are two things I would do : in the first place, I would found a Chair at one of our more progressive medical schools and instal in it a man whose duty it would be to give as part of the clinical training of every student a course of lectures in the prevention of disease by good food. Something must be done to dispel from the medical man's mind the idea that vitamins are a kind of medicine to be prescribed for certain disorders, much as you give quinine to counter malaria. It has been said with much wisdom that it is better to build a fence at the top of the cliff than to maintain an ambulance at the bottom—incidentally, it is also cheaper. We do need to make it more clearly understood that, apart from all humanitarian considerations, the proper feeding of the people is a question of national insurance. This aspect of the future of nutrition has always seemed to me so obvious that it has surprised me that those whose job it is to understand the basic principles of insurance have not appreciated years ago its potential value to them. When I was in Canada recently I found, however, that they had got hold of the idea. One of the largest insurance companies in the Dominion is contributing $500,000 towards the cost of the national nutrition propaganda campaign because they are convinced that it is the most promising project for improving health and increasing expectation of life. The second benefaction I would make would be to finance the sending to each of about half a dozen countries of a small, well qualified and equipped team of young medical men and nutrition experts, trained to correlate on the spot information about diet and the incidence of disease. I would send one team to the heavy meat‐eating areas of the South American plains. They would solve in a year or two the long disputed question whether very high protein intakes are harmful to health and liable to produce certain disorders. I would send another team to South‐Eastern Europe to one of the areas where the peasants live almost entirely on vegetables, coarse bread and goats' milk. Is it true that these people have a very low incidence of digestive disorders and hardly ever suffer from cancer of the digestive tract? We do not know, but a team using standardised methods of examination and survey would not be long in finding the truth. Dr. Sinclair and his Oxford Nutrition Survey team has prepared the model of what is required. Such teams will, I believe, be widely used in the post‐war years. They may actually be required even earlier. They would be invaluable if they could be rushed into territories as soon as they are liberated from the enemy, where their task would be to survey and advise on the nutritional conditions of the liberated people—which in many cases, we fear, are likely to be grievous. War has few virtues. One undoubtedly is that activity in many fields of enterprise is enormously stimulated. Another is that problems can often be lifted clear of the arena of political dispute. This war of liberation will offer some compensation for the devastation and waste of human effort if it brings nearer by years the day when every man, woman and child can be assured that they will never know the want of the foods on which their health depends. Not until that day dawns can the Atlantic Charter, calling for freedom from fear, freedom from want, become reality.

On April 22, 2005, Maytag Corporation's stock price fell 28 percent after the company reported disappointing first-quarter results and significantly reduced its earnings outlook for 2005. The company's sales were declining due to increased foreign competition and its production costs were increasing due to higher energy, materials, and distribution costs. Maytag's management and board clearly understood the need to make strategic decisions to turn around the fate of their company. Maytag could propose a drastic turnaround plan and remain independent, sell itself to either a large domestic competitor such as Whirlpool or a foreign firm such as Haier, or it could choose to go private by selling to a financial buyer (Ripplewood).

This case is designed to introduce and to practice concepts relating to the valuation of an acquisition target from the perspectives of a strategic investor and a private equity (leveraged buyout) firm. More specifically, the exercise is intended to address: (1) corporate strategy relating to takeover contests, (2) sources of value creation in acquisitions, and (3) valuation methodologies used to determine target company values.

The purpose of this paper is to examine the role of school discipline in achieving academic performance. The study aims to clarify the role of permissive vis-à-vis authoritative teaching styles with an overarching hypothesis that better discipline leads to better academic performance. The authors also probe whether uniformed students have better discipline.

The authors analyse Organisation for Economic Co-operation and Development’s Programme for International Student Assessment data on school discipline dimensions: students listening well, noise levels, teacher waiting time, students working well, class start time. Analysis of variance (ANOVA) with post hoc analysis on five geographic groups established by Baumann and Winzar (2016) was applied to test for geographic differences (Europe, Americas, Far East Asia, Rest of Asia, Anglo-Saxon cluster) in school discipline. ANOVA was further used to test for school discipline and academic performance. Third, t-tests on five discipline dimensions were run to test for differences between students who wear uniforms and those who do not.

The results demonstrate differences in school discipline across five geographic clusters, with East Asia leading the way. The authors demonstrate significant differences in discipline for low, medium and high performing students. Peak-performing students have the highest level of discipline. Students wearing a uniform listen better with lower teacher waiting times.

Students peak perform when teachers create a disciplined atmosphere where students listen to teachers, where noise levels in the classroom are low and they do not have to wait to start class and teach. Good discipline allows students to work well and this ultimately leads to better academic performance. Uniforms contribute to better discipline in everyday school operations. The findings support that in general, implementing school uniforms at schools might enhance discipline and allow for better learning. The authors recommend keeping uniforms where they are already used and to consider introducing uniforms where they are not yet common.

AT the close of the year we look back upon twelve very chequered months in the story of librarianship. In the field of libraries as a whole, it may be said that they held their own and indeed that some progress has been made. A few libraries have been opened, mostly branch libraries, but there have been extensions and re‐organisations of central libraries, which point to a universally developing regard for the library service. Even if this has not been dramatic in some places, it has nevertheless been real. Men who were middle‐aged before the war must, however, pass away before we get the right perspective for the conditions of to‐day; that is to say, with few exceptions. We are not speaking of librarians here, but of those who control libraries, but even librarians of the older school have sometimes found it difficult to envisage library service on the scale common in America, which, with adjustments to British circumstances, should be the scale for us throughout the Empire.

MR. F. W. F. ARNAUD, the Public Analyst for the Borough of Portsmouth, delivered a lecture on this subject at the Town Hall on April 27. The lecturer commenced his address by stating that many of the objections to the use of certain preservatives which he might have occasion to put forward were not necessarily his own individual objections, but were the objections of many scientific men who had dealt with all sides of this difficult subject. There was a tendency on the part of some people to regard preservatives as disinfectants, but disinfectants and antiseptics were two different things. A disinfectant not only retarded the growth of microbes, but actually killed them, while an antiseptic preservative merely retarded their growth or formation. Two common antiseptics were sugar and salt. It had been contended that a small dose of a chemical preservative was preferable to a dose of microbes. The effect of a preservative was not to kill the life already present, but to prevent the free multiplication of the organisms present, and the swallowing of a dose of preservative did not necessarily prevent the swallowing of a dose of microbes. There were many old forms of preserving food, such as the use of sugar for fruit and condensed milk; of vinegar for vegetables; and the process of smoking for bacon and fish, smoke being very destructive to microbes; but the oldest form of preservation was the process of salting meat and fish. Another form of preservation was the method of preventing the access of air to perishable articles, as in the cases of eggs and lard. Then there was drying, as in the case of fruit, and chilling, or freezing, as in the cases of meat, milk, poultry, and fish. The temperatures employed for freezing food varied considerably, and depended chiefly upon the length of time during which storage was necessary. If it were only desired to keep meat for a week or two, a low temperature was not necessary, but one of 40 deg. F. was sufficient. Any cooling process was equivalent to the use of a great deal of chemical preservative. A cooling to 50 deg. P. was equivalent to the addition of boric acid to the extent of .05 per cent. At a normal summer temperature of 70 deg. P., two microbes would produce 62,100 in the course of twenty‐four hours; hence the necessity for cooling articles of food. The drawback to most of these methods of preservation was that sugar, salt, and cold were not applicable in every case. Exclusion of air and subsequent sterilisation had their drawbacks also. When sterilisation was complete and the air was exhausted, no putrefaction could take place, and the food should remain indefinitely unchanged. In the matter of tinned meat, the drawback lay chiefly in the failure to ensure complete sterilisation, and in the dissolving of tin, and occasionally lead, from the metal enclosing the food. In the case of tinned meat putrefaction to any considerable extent could be easily recognised by the blown condition of the tin and an absence of the inrush of air when the tin was pierced. Such food was a source of great danger, and if eaten the meat was liable to give rise to ptomaine poisoning—which was occasioned by eating the poisonous products produced by various bacteria. The danger of metallic poisoning could be largely overcome by the use of glass or earthenware vessels. Preservatives in use at the present time were: Benzoates, fluorides, formalin, salicylic acid, sulphites, saccharin, and beta naphthol, generally used singly, though there were some very complicated preservatives on the market. With reference to the use of salt and sugar as preservatives, little or nothing could be said against their use, for sugar was in itself a food and had a well‐known food value. Salt, too, was an essential constituent of our food, for without the elements of which it was composed we could not exist. Naturally, the assimilation of a large quantity of salt was not desirable, but it could not be urged, as, for instance, in the case of boric acid, that it was a substance foreign to the constituents of the human organism, for it was indispensable. Boric acid, however, played no part in any of the essential life processes.
