RESEARCH REPORT

The purposes of this study were: to compare students' performance on conceptual and algorithmic chemistry problems; to investigate the relationships between learning orientation, formal reasoning, and mental capacity and students' performance on conceptual and algorithmic problems; and to investigate interactions among learning orientation, formal operational reasoning, and mental capacity. Participants were Grade 11 students enrolled in scientific sections of three Lebanese schools. Learning orientation, formal reasoning and mental capacities were measured using the Learning Approach Questionnaire, the Test of Logical Thinking, and the Figural Intersection Test, respectively. Also, students solved conceptual and low M-demand and high M-demand algorithmic chemistry problems. Students' performance on conceptual and algorithmic problems was compared. Regression analyses were used to examine the predictive power of the cognitive variables on each type of chemistry problems. In addition, performance of meaningful and rote learners was compared on all types of problems. Results showed that students performed significantly better on algorithmic than on conceptual problems. Moreover, meaningful learners outperformed rote learners on a test of conceptual problems while no significant differences existed for both levels of algorithmic problems. The three cognitive variables were significant predictors of performance on conceptual chemistry problems but not on algorithmic problems.

Meeting Highlights: Central & Peripheral Nervous Systems: Summary of the 97th Annual Meeting of the American Society for Clinical Pharmacology and Therapeutics

The 97th annual meeting of the American Society for Clinical Pharmacology and Therapeutics (ASCPT) was held on March 20 – 22, 1996. Lectures, symposia, and poster/slide presentations focused on both new compounds in early clinical development and novel findings with older marketed compounds. Attendees had the opportunity to listen to state-of-the-art lectures on four topics: 1) apoptosis as a mechanism of action of anticancer drugs; 2) structure-based drug design; 3) molecular biology of neurotransmitter uptake systems; and 4) present and future prospects for human gene therapy. In the evenings, workshops and meetings of scientific sections were held that focused on specific topics of interest to the members of ASCPT. The following is a summary of some of the poster and slide presentations made at the ASCPT meeting. Four broad general topics are covered in this summary: 1) studies performed with cytochrome p450 isozymes; 2) studies with new antimigraine compounds; and 3) studies with alpha-1 adrenergic blockers; and 4) general regulatory and drug development issues.

Multiple authorship, basic research, and other trends in the emergency medicine literature (1975 to 1986)

As emergency medicine comes of age, it is interesting to examine the scientific nature of the specialty as reflected in the literature. Representative volumes of three emergency medicine journals were reviewed for number and type of article, institutional origin, article length, and number of authors. For Annals of Emergency Medicine, (AEM) volumes for 1975, 1980, and 1985 were studied. For The American Journal of Emergency Medicine (AJEM) and The Journal of Emergency Medicine (JEM), articles from the first 12 months of publication (1983 to 1984) and the complete 1986 issue were examined. Analysis of the scientific sections of the journals discloses some interesting trends. While the average article length has remained about the same (four to six pages), the average number of authors per article has steadily risen. The percentage of articles listing an academic origin has remained steady in AEM and JEM, but has risen in AJEM. Multicenter collaborations and basic science articles are appearing with significantly increased frequency. A noteworthy trend is the rise in multiple authorship of articles. There have been significant p < 10 −4) increases in the number of multiple-authored (more than three authors) articles in AEM and JEM. As reflected by the literature, scientific progress in EM is maintaining a rapid pace. However, there are increasing numbers of papers with multiple authors. Listing of multiple authors on papers has prompted critlcism of the literature in other medical specialties. If this trend continues, there may be a risk of compromising the integrity of the published research.

Royal Society of Canada

ANNUAL MEETING THE meeting of the Royal Society of Canada for 1945 was held at Queen's University, Kingston, Ontario, during May 20–23, under the chairmanship of the president, Prof. J. K. Robertson, professor of physics at Queen's University. In the scientific sections, one hundred and four fellows, and half as many guests, were in attendance.

ROYAL SOCIETY OF CANADA

ANNUAL MEETING THE annual meeting of the Royal Society of Canada was held at McMaster University, Hamilton, Ontario, during May 25-27. The scientific sections of the Society held their meetings in the Science Building of the University and the general meetings took place in Convocation Hall. The president of the Society, Prof. J. B. Collip, presented the medals at the evening meeting on May 25. The Flavelle Medal was awarded to Prof. B. P. Babkin, research professor of physiology at McGill University, for his outstanding work in analysing the secretory mechanisms of the digestive glands. Prof. John L. Synge, professor of applied mathematics in the University of Toronto, received the first award of the Henry Marshall Tory Medal for outstanding contributions to applied mathematics; and the Willet G. Miller Medal, also awarded for the first time, was presented to Prof. Norman Levi Bowon, distinguished service professor of petrology in the University of Chicago, in recognition of his contributions to geology. Following the presentation of the medals, Dr. Collip read his presidential address on "Science and War". After briefly reviewing the part played by science in former conflicts, Dr. Collip emphasized the important contributions of physicists, chemists and other men of science in the present War. He dealt in some detail with aviation medicine and the co-operation between the men of science and the armed forces in solving many of the problems which modern warfare presents. He referred to the recognition and support that scientific workers are now receiving as an integral part of the war effort, and pointed out that much of this research work is producing results that will be equally important in the post-war period.

Medical Research in Egypt

THE fifth annual report of the Research Institute and the Endemic Diseases Hospitals, Cairo, by the director, Dr. M. Khalil Bey, contains a summary of the reports of the scientific sections and the clinical reports, including investigations on Egyptian splenomegaly, anaemias and various parasitic affections. A report is also included of the work of the Khanka Malaria Research Station. This gives the results of a mosquito survey of the area, with the species of mosquitoes found, and a description of some of the preventive measures undertaken. These include drainage, filling up of water holes and clearance of water-weeds in places. Breeding places of mosquitoes are treated with Paris green when there are Anophelines only, or with mazout oil if Culex larvae are also present. In future, the Institute will be named the “Fouad the First Institute and Hospital for Tropical Diseases”.

The British Medical Association Centenary

All the usual features of the annual gathering were provided, but on a larger and more sumptuous scale, to do honour to the occasion: the scientific sections were more numerous and better attended than ever before; the Exhibition was larger; the entertainments were more lavish and varied, and the brilliance of the social gatherings was unprecedented. Few who were present at the President's Reception will ever forget the vast circle of the Albert Hall with its three tiers of boxes filled with doctors in brilliant academic robes, eclipsing for once the splendour of their wives and daughters, while the huge dance floor was thronged with as many more, and for over an hour a ceaseless procession of members and guests from all parts of the world filed before the President and Lady Dawson.When the British Medical Association celebrated its jubilee, the discovery of the Röntgen ray was yet twenty-three years in the future. The word “Radiology” first appeared in the list of the scientific sections in 1910, when it was added to the title of the Section of Medical Electricity, but that section had been hearing radiological papers for many years previously. Indeed, radiological papers first appear in the programme for 1896: within a year of Röntgen's discovery! Before the Section of Medicine in that year, Dr. John Macintyre of Glasgow demonstrated the use of X rays in medicine with special reference to the soft tissues, while Mr. Mackenzie Davidson showed the surgeons the “apparatus necessary to produce Roentgen X rays, and skiagrams of cases illustrative of its use in surgery.” Next article FiguresReferencesRelatedDetails Volume 5, Issue 56August 1932Pages: 609-672 © The British Institute of Radiology History Published onlineMay 29,2014 Metrics Download PDF
