Journal description

The Lancet is the world's leading independent general medical journal. The journal's coverage is international in focus and extends to all aspects of human health.The Lancet is published weekly from editorial offices in London and New York. It aims to publish the best original primary research papers, and review articles of the highest standard. The Lancet is stringently edited and peer-reviewed to ensure the scientific merit and clinical relevance of its diverse content. Drawing on an international network of advisers and contributors, The Lancet meets the needs of physicians by adding to their clinical knowledge and alerting them to current issues affecting the practise of medicine world wide. The blend of challenging editorials, signed commentaries, original research, commissioned reviews, an international news section, and the views of readers in the letters pages make The Lancet an essential weekly read for physicians all over the world.The Lancet is available by personal subscription to individual physicians. It is also available by subscription to institutions, libraries, and biomedical companies.Visit The Lancet's World Wide Web site to find out more - http://www.thelancet.com

Speaking at meetings is a quicker way of reporting work than writing articles. Unfortunately, as the number of medical meetings increases, the communications delivered become harder to understand. There are several reasons for this. Formerly the contents of papers often consisted of brief descriptions of clinical or pathological conditions, whereas today scientific papers may occupy an entire session. Greater care is then demanded from the speaker and sometimes more intelligence from his audience. Priority is given to research. Also, the trend towards specialisation — each speciality with its own jargon and terminology — creates problems in intercommunication. One sometimes wonders whether general meetings will not soon become impracticable. Nevertheless, none of these developments should prevent a communication being understood, provided that it is properly delivered. Sometimes in a meeting lasting many hours, one communication only may be conspicuous for its clarity and fine slides — its presentation so concise and easy that few appreciate the work that went into its construction.
This paper describes the work of the research and intelligence unit in Teesside Health Department, and illustrates the use of information in health-service planning. The validity of this more scientific approach to management is demonstrated. It is concluded that a research and information function should be developed as soon as possible, because of the need for the provision of data for decision-making in the early days of the reorganised N.H.S.
In a previous paper (JAAVSO37, 2009, p. 71) we used self-correlation to analyze AAVSO visual observations of twenty-three L-type (irregular) pulsating red giants, and found that they exhibited a continuous spectrum of behavior, from truly irregular to semiregular. In this paper, we carry out Fourier analysis of the same stars, partly to investigate whether some of their irregularity might be due to multiperiodicity, and partly to look for evidence of possible spurious periods of one year and one month, due to the methodology of visual observing. We find evidence of such spurious periods in many stars. We have also analyzed an additional seventeen L-type pulsating red giants, using both self-correlation and Fourier techniques. Several show evidence of spurious one-month or one-year periods. Only XY Lyr, VY UMa, and possibly DY Vul and BU Gem show evidence of intrinsic periodicity. Several show little or no variability. The rest vary irregularly on time scales of a few hundred days. We find no evidence that irregularity in L-type variables is due to multiperiodicity.
