As is usual, the volumes of Biographical Memoirs contain much material of interest to the student of the mathematical, physical, engineering, biological and medical sciences. Often a memoir has been written in collaboration with another Academy or Society. In the present volume the memoir of Shiing-Shen Chern is an expanded version of an obituary notice by Nigel Hitchin that appeared in the Bulletin of the London Mathematical Society . Chern was a great geometer, who revolutionized differential geometry and whose mathematical tools are now common currency in geometry, topology and theoretical physics. His proof of the Gauss–Bonnet theorem, which was a pivotal event in the history of differential geometry, led to the importance of the Chern classes. Moreover. S.-S. Chern was extremely influential in the development of mathematics and geometry both in the USA, at the Institute of Advanced Study, Princeton, and Chicago and Berkeley, and in China, in Shanghai and Nankei.

Shiing-Shen Chern was a towering figure in mathematics, both for his contributions to differential geometry and as a source of inspiration and encouragement for all mathematicians, and particularly those in China. Born in the final year of the Qing dynasty, and educated at a time when China was only beginning to set up Western-style universities, he lived to preside over the 2002 International Congress of Mathematicians in Beijing. He was a co-founder of the Mathematical Sciences Research Institute in Berkeley and its first Director in 1981; he also set up the Nankai Institute for Mathematics in 1985. His contributions to differential geometry were of foundational importance for the global viewpoint that developed in the postwar years, and the mathematical tools he introduced are now the common currency in geometry, topology and even aspects of theoretical physics.

History Of

The history of the evolution of medical research is characterized by a long period of division between the basic biological sciences and the health sciences, reflecting the seventeenth-century trends towards the experimental and the empirical. It was not until the middle of the twentieth century that, by their ability to straddle both worlds, the work of small groups of basic scientists in the USA and Europe led to closer integration between the medical sciences. This change in direction is well exemplified by the work of the Cambridge scientists Max Perutz, Vernon Ingram and Herman Lehmann, from 1950 onwards. Their research, and its later development by others, was to lay the basis for what became known as ‘molecular medicine’, and at the same time set the scene for a more integrated approach to medical research that continued into the new millennium.

Positive Economics

The article examines in detail the argument of M. Friedman as expressed in his famous article "Methodology of Positive Economics". In considering the problem of interconnection of theoretical hypotheses with experimental evidence the author illustrates his thesis using the history of the Galilean law of free fall and its role in the development of theoretical physics. He also draws upon methodological ideas of the founder of experimental economics and Nobel prize winner V. Smith.

History Of

In Hungary one can mostly find references to the psychological processes of politics in the writings of publicists, public opinion pollsters, philosophers, social psychologists, and political analysts. It would be still important if not only legal scientists focusing on political institutions or sociologist-politologists concentrating on social structures could analyse the psychological aspects of political processes; but one could also do so through the application of the methods of political psychology. The authors review the history of political psychology, its position vis-à-vis other fields of science and the essential interfaces through which this field of science, which is still to be discovered in Hungary, connects to other social sciences. As far as its methodology comprising psycho-biographical analyses, questionnaire-based queries, cognitive mapping of interviews and statements are concerned, it is identical with the psychiatric tools of medical sciences. In the next part of this paper, the focus is shifted to the essence and contents of political psychology. Group dynamics properties, voters’ attitudes, leaders’ personalities and the behavioural patterns demonstrated by them in different political situations, authoritativeness, games, and charisma are all essential components of political psychology, which mostly analyses psychological-psychiatric processes and also involves medical sciences by relying on cognitive and behavioural sciences. This paper describes political psychology, which is basically part of social sciences, still, being an interdisciplinary science, has several ties to medical sciences through psychological and psychiatric aspects.

The Impact

The history of human society is replete with examples of advances in technology overrunning the ability of societal organizations to efficiently handle the resulting massive societal dislocations. The social impacts of the “Industrial Revolution of the 18th and 19th Centuries” illustrate how profound such effects can be. The automation-computer-robotics revolution now underway also has the potential for serious societal changes. In this regard public works activities are subject to increasing amounts of automation with impacts upon current and net total employment and training needs. To evaluate the present status of automation in the USA, questionnaires were sent to public works authorities in 110 cities or agencies. The current degree of automation, the impact upon employment and the skills now needed by public works employers were queried. It was found that in most cases automation was just starting; but that as complete automation as was possible was inevitable given the increasing complexity of the tasks, the demands of the public and the long term prospects for public works funding. In many cases the candidates now in the work force were not properly trained for automation needs. Retraining and changes in the educational system appeared necessary if the employees now needed were to be continuously available. Public works management as well as several labor organizations appeared to be aware of this need and were organizing to handle the training problem and the changes in employment qualifications now necessary. It appeared to be a consensus that the larger societal effects of automation should be handled by society as a whole.

Selective Culling

AbstractBovine respiratory disease (BRD) is a frequent disease concern in dairy cattle and is most commonly diagnosed in young dairy heifers. The impact of BRD is highly variable, depending on the accuracy and completeness of detection, effectiveness of treatment, and on-farm culling practices. Consequences include decreased rate of weight gain, a higher culling risk either as heifers or as cows, delayed age at first service, delayed age at first calving, and in some cases, lower future milk production. In this data set of 104,100 dairy replacement heifers from across the USA, 36.6% had one or more cases diagnosed within the first 120 days of age with the highest risk of new cases occurring prior to weaning. Comparison of the raising cost for heifers with BRD and those without a recorded history of BRD resulted in an estimated cost per incident case occurring in the first 120 days of age of $252 or $282, depending upon whether anticipated future milk production differences were considered or not. Current market conditions contributed to a cost estimate that is significantly higher than previously published estimates, driven in part by the losses associated with selective culling of a subset of heifers that experienced BRD.

A 25-year-old Filipino woman living in the USA was evaluated for a 5-month history of left eye pain and a subsequent orbital mass. Histopathological analysis of the lacrimal mass showed a mixed inflammatory process with necrotising granulomas and positive cultures for Mycobacterium tuberculosis. She was treated with antituberculosis therapy, with resolution of symptoms. Tuberculosis dacryoadenitis is extremely rare in the USA and other developed countries. It requires a high degree of clinical suspicion with special attention to the patient’s history to make the correct diagnosis. It can be treated successfully with antituberculosis therapy.
