The International Tin Study Group, which parallels in general the other international study groups established for commodities, was created by an international conference held in London in October, 1946. Its functions are to review periodically the world supply and demand position of tin and to make recommendations to the member governments.

AbstractWe propose a simple model of the international monetary system. We study the world supply and demand for reserve assets denominated in different currencies under a variety of scenarios: a hegemon versus a multipolar world; abundant versus scarce reserve assets; and a gold exchange standard versus a floating rate system. We rationalize the Triffin dilemma, which posits the fundamental instability of the system, as well as the common prediction regarding the natural and beneficial emergence of a multipolar world, the Nurkse warning that a multipolar world is more unstable than a hegemon world, and the Keynesian argument that a scarcity of reserve assets under a gold standard or at the zero lower bound is recessionary. Our analysis is both positive and normative.

Purpose: To investigate the amount of gas released from Zenith thoracic stent-grafts using standard saline flushing vs the carbon dioxide flushing technique. Methods: In an experimental bench setting, 20 thoracic stent-grafts were separated into 2 groups of 10 endografts. One group of grafts was flushed with 60 mL saline and the other group was flushed with carbon dioxide for 5 minutes followed by 60 mL saline. All grafts were deployed into a water-filled container with a curved plastic pipe; the deployment was recorded and released gas was measured using a calibrated setup. Results: Gas was released from all grafts in both study groups during endograft deployment. The average amount of released gas per graft was significantly lower in the study group with carbon dioxide flushing (0.79 vs 0.51 mL, p=0.005). Conclusion: Thoracic endografts release significant amounts of air during deployment if flushed according to the instructions for use. Application of carbon dioxide for the flushing of thoracic stent-grafts prior to standard saline flush significantly reduces the amount of gas released during deployment. The additional use of carbon dioxide should be considered as a standard flush technique for aortic stent-grafts, especially in those implanted in proximal aortic segments, to reduce the risk of air embolism and stroke.

A few years ago, the academic community around the world focused its attention on an immense international attempt to study on the one hand the differences among the school systems of twelve countries and, on the other, their effect on ach ievement, interests. and attitudes of certain groups of school-attendi ng youngsters. Those objectives and their findings were reported through many publications, most notable in International Study of Achievement in Mathematics (Husén, 1967). These publications have motivated me to raise some serious questions.

The possibilities of real individualization of education in Russian universities are constrained by the peculiarities of the type of organization of the educational process. Almost all Russian universities are characterized by stream-group organization of training, in which study groups and streams are formed once for the entire period of study. Students of each study group during the entire period of study have a common curriculum and a common schedule of training sessions. Opportunities for individualization of curricula and programs are very limited and confined to the choice of a foreign language and one of several disciplines of the socio-economic cycle. In modern higher education, the stream-group organization of education is preserved only in Russian universities, universities of the post-soviet and partially post-socialist space. Most universities in the rest of the world uphold the principles of individually-oriented organization of training, according to which each student has an opportunity to choose from the curriculum modules to study in the next semester, choose the teachers and the time of classes. In accordance with the choice of students, groups and streams are formed, which retain only during the current semester. Thus, we emphasize, not individual persons but all the students of modern universities have individual curricula and schedules of training sessions. The article discusses the opportunities and prospects of the individualization of education at Russian universities.

SummaryThe British system for anticoagulant control based on the use of a national reagent with a national system of reporting supported by national quality control using lyophilized plasma preparations appears to offer a model which many countries abroad seem interested in adopting to solve their own national problems. Good progress has already been made in this direction in some Commonwealth countries and in South Africa. At a symposium at the 3rd Mediterranean Congress on Thromboembolism in 1973 invited participants from all over the world agreed to set up an International Study Group to provide an international organisation for anticoagulant control, and an encouraging start has been made.

International education! Since the publishing of the International Study of Achievement in Mathematics: A Comparison of Twelve Countries this past spring, many mathematics educators have taken a closer look at the educational systems of the world. It is appropriate that The Arithmetic Teacher should fea ture international mathematics education in this issue. One of the articles here deals with the study mentioned above; the other articles describe various national systems or experiments in mathematics education. Nearly all the articles have some international flavor.

The International Lead and Zinc Study Group held its second session, attended by delegates from 23 countries, in Geneva, September 12–15, 1960, according to the press. Mr. G. J. MacMahon (United Kingdom) presided over the session, the main purpose of which was reportedly to review the current statistical situation in lead and zinc. In regard to lead, the Study Group was stated to have observed that, after taking into account net trade with the centrally-planned economies, the balance between new supplies and demand showed a statistical surplus of lead metal of 21,000 tons for 1960 and 26,000 tons for 1961, with producers' stocks of lead metal at the very high level of 334,000 tons in July of the current year, divided about evenly between the United States and the rest of the world. New supplies, the report continued, appeared to be in better balance with anticipated demand than in recent years, but statistics, which as of the end of June showed metal stocks in the hands of producers to amount to 276,000 tons, did not indicate any immediate prospect of a significant change in stocks. With regard to zinc, it was announced that the steady rise in consumption was expected to continue in 1960 and 1961, and an even greater increase in production was forecast, although most. delegations were said to feel that action by the Study Group was not necessary, since stocks in many countries were at normal levels or below. In reply to concern expressed by some delegations about the continued existence of protective restrictions and about releases from noncommercial stocks, governments were urged not to impose additional barriers to trade in this field, and both governments and industries were urged to avoid any course which might frustrate the efforts being made to bring about a satisfactory balance between supply and demand.
