Food recommendations in domestic education,Belgium 1890–1940

This paper addresses the question of dissemination of nutritional knowledge in textbooks of household schools between 1890 and 1940. It starts by considering the nature of food recommendations in manuals that are used in Belgian household schools, and then deals with the sources that are referred to by those who give food advice, comparing the latter to the state of the art of nutritional knowledge. If, prior to 1925, school manuals referred to working-class households, paid attention to abundant and economical food, recommended meat, hardly cared about breakfast and connected food to health in a general way, the manuals of the late 1920s and 1930s discussed the average consumer, advised limited meat consumption, warned against unbalanced diets that could lead to specific diseases and recommended required amounts of calories and vitamins. Textbook authors rarely referred to their sources – and if they did, international names were hardly mentioned – which raises the question of the value of the information in these textbooks. Yet from the late 1920s onwards, more direct references were made to science and researchers, which may be linked to the strengthening of scientific authority within society.     

One Work in Two Places

Abstract

Over the years, the publishing industry has packaged single works of printed resources with accompanying media such as 3.5″ disks, CD-ROMs, videocassettes, audiocassettes, or web sites. Recognizing the importance of the information provided in the accompanying media and the library clients' access to them, the Library of Rush University (LRU) at Rush-Presbyterian-St. Luke's Medical Center developed and implemented “mixed media” policies and procedures. This paper discusses issues and Rush Library responses to the issues surrounding the management of “mixed media” titles in selection, cataloging, labeling, housing, circulation, loading data files, and the publicity that puts them in the client's hands.     

The first joint BASES/BASEM Conference

The purpose of this study was to evaluate the dietary practices of soccer players of different ages. The diets of the members of four soccer teams (mean ages of 14.0, 15.0, 16.6 and 20.9 years, respectively) were examined. Our results show that the caloric intake per kilogram of body mass was significantly higher among the youngest players when compared with the adult players (P 相似文献

Supplemental Income

The introduction of colour supplements by three ‘quality’ newspapers during the 1960s was a key development in the British press during the decade, and was described by the editor of the Sunday Times as ‘perhaps the most successful single innovation in post-war journalism’. This article provides an overview of the advent of the colour supplements, explaining why they emerged when they did and developed in the manner they did, and exploring some of the difficulties and issues that attended their arrival. The article also demonstrates that sections of the British press were capable of taking advantage of changes in print and advertising culture brought about by the arrival of the post-war consumer society. However, the term ‘colour supplement’ became pejorative shorthand for the perceived vacuity of this new society, in part because of the tension that existed between the editorial and advertising content of these modish new publications. Consequently, the success of the colour supplement experiment was not universally celebrated.
