Education and Training in the Mining Industry, 1750-1860: European Models and the Italian Case

Mining education was one of the areas of technical savoir transformed during the eighteenth century. Mining academies arose and spread through Europe in the second half of that century. This happened first in the German states and the Austrian dominions, due to the cameralistic system, and soon developed elsewhere through a transfer of the German model to France (Ecole des mines) as well as to other francophone and Spanish-speaking areas (Belgium and Piedmont-Savoy, Spain and America). The mining academies may rightly be considered among the prototypes of technical high schools (Polytechniques and Technische Hochschulen) established during the nineteenth century. In the course of exploring some of the details of this development, the present paper aims at suggesting outlines to be followed in pursuing a comparative analysis of special schools for the training of technicians and mining officers (Bergschulen and Bergakademien). A second aim is to examine more closely the Italian case as a typical example of adaptation, although on a smaller scale, of French and German experiences. This can provide a framework within which to place further microanalyses and case-studies.     

Eugenics and politics in Britain in the 1930s

This paper discusses the surprising resurgence in the fortunes of the British eugenics movement in the 1930s. It is argued that although mass unemployment may in the long run have discredited that version of eugenics in which social dependence and destitution were attributed to genetic defect, in the short run the Depression was often perceived as a vindication of the eugenical creed. In particular, the attempt to reduce the fertility of the unemployed by popularising birth control techniques, and the voluntary sterilization campaign aimed at preventing the propagation of defectives from the so-called Social Problem Group, satisfied the urge felt by many conservative members from the professional classes to respond creatively to the country's crisis, without endangering existing social and economic institutions. It is also shown that not until 1938 did events in Germany cause substantial damage to the cause of eugenics in Britain. In fact, the ‘German experiment’ was actually greeted with approval by certain British eugenists of an authoritarian cast of mind. However, the Society as a whole never identified with these right-wing extremists, thanks in part to the moderating influence exercised by its General Secretary, Dr. C. P. Blacker, whose prime concern was with psycho-medical problems likely to concern people of all party persuasions.     

生物能量在生命体中传递的新理论及应用

生物能量在生物体当中的传递是生命科学中的一个基本问题,它相关于ATP水解放出的能量沿着蛋白质分子的传递。这种传递与蛋白质的动力学相关。根据ATP分子分布和水解的特性以及蛋白质结构的特点,在Davyclov理论的基础上提出了一个新的生物能量传递的理论。在这个理论当中,Amide振动的集体激发状态用一个两量子准相干态表示,系统的哈密顿量不但包含了Amide振动引起的相邻氨基酸残基的位移,而且包含了相邻Amide之间的共振相互作用所引起的氨基酸残基的相对位置的改变。由这个理论得出的传递生物能量的孤子的寿命可得10^-10秒,在这个时间之内孤子能传递过上千个氨基酸残基,因此它能在生物过程中起着重要的作用。这个理论与E．col．的Ramma谱的实验结果和我们做出的胶原蛋白的红外吸收谱等实验结果相一致,因此它可能是生物体中生物能量传递的一个可利用的和正确的理论。

Early laboratories c.1600 - c.1800 and the location of experimental science

Surprisingly little attention has been given hitherto to the definition of the laboratory. A space has to be specially adapted to deserve that title. It would be easy to assume that the two leading experimental sciences, physics and chemistry, have historically depended in a similar way on access to a laboratory. But while chemistry, through its alchemical ancestry with batteries of stills, had many fully fledged laboratories by the seventeenth century, physics was discovering the value of mathematics. Even experimental physics was content to make use of almost any indoor space, if not outdoors, ignoring the possible value of a laboratory. The development of the physics laboratory had to wait until the nineteenth century.     

‘Physics and fashion’: John Tyndall and his audiences in mid-Victorian Britain

This paper explores how the physicist John Tyndall transformed himself from humble surveyor and schoolmaster into an internationally applauded icon of science. Beginning with his appointment as Professor of Natural Philosophy at the Royal Institution in 1853, I show how Tyndall’s worries about his social class and Irish origins, his painstaking attention to his lecturing performance and skilled use of the material and architectural resources of the Royal Institution were vital to his eventual success as a popular expositor and ambassador for science. Secondly I explore the implications of Tyndall’s ‘popularity’ with respect to debates over the meaning and value of scientific ‘popularisation’. In support of recent work challenging diffusionist models of science communication, I show how Tyndall’s interactions with his audiences illustrate the symbiotic relationship between producer and consumer of ‘popular’ science. By examining the views of Tyndall’s critics—notably the ‘North British’ group of physicists—and his defenders and rivals in the domain of popular scientific lecturing, I show that disputes over Tyndall’s authority reflected anxieties about what constituted popular science and the transient boundaries between instruction and entertainment. The term ‘popularisation’ enjoyed many different uses in these debates, not least of all as a rheorical device with which to either exalt or destroy a scientist’s credibility.

William Whewell,natural theology and the philosophy of science in mid nineteenth century Britain

This article aims to reveal the moral and theological dimensions of William Whewell's philosophy of science. It suggests that, in addition to an internalist account of Whewell's method and epistemology, there is a need to view his philosophy of science (and knowledge) within the intellectual context constituted by the assumptions of natural theology. It argues that writers of natural theology saw man's ability to know the world as an indication of his special place in nature, and that epistemological theories were therefore invested with moral and theological significance. Whewell's work is interpreted as an attempt to dissociate natural science from Utilitarianism and empiricist philosophy: he sought to promote a philosophy of science which guaranteed the principles of natural theology and the values of Christianity. But the idealist epistemology which he proposed was criticized by both scientists and theologians. In 1853 (in his book Of the plurality of worlds), again within the framework of natural theology, Whewell attempted to justify this epistemology by affirming the metaphysics of a Christian Platonism. From this position, Whewell defended natural theology against the metaphysical scepticism of both Henry Mansel and the positivists.

Seasonality in the reproductive phenology ofFicus: Its evolution and consequences

Summary Ficus can only reproduce if they are pollinated by mutualistic wasps that breed within the figs. Pollen-loaded wasps enter the figs when the female flowers are receptive. Several weeks later, their offspring load pollen within the fig and then emerge. As individual trees typically produce crops of synchronous figs at long intervals, the shortlived wasps have to move to another, receptive, tree. The wasp population can only survive, and hence the fig population reproduce, if there are trees fruiting all over the year. When only few trees are present within a population gaps in the flowering sequence may lead to the extinction of the local pollinator population. Two models are presented. One investigates the number of trees necessary in order to sustain a local pollinator population when the tree population has a seasonal pattern of fruiting. The second model investigates how such a seasonal pattern may evolve within a fig population as a result of individual selection on the trees. It is shown that pollinator populations are fragilized under seasonal conditions. Hence, the breeding system ofFicus limits their expansion into highly seasonal habitats. Seasonal habitats may also lead to seasonal adjustment of male versus female investments and to the evolution of dioecy.     

Analysis and prediction of the population in Spain: 1910-2000

"The starting hypothesis of this paper was the actual occurrence of important interactions between demographic and socio-economic factors when trying to reach population forecasts that may be more efficient than those obtained by mere extrapolative methods. In order to be able to implement this approach to the Spanish case it has been necessary to reconstruct first the Spanish population series by age and sex groups from 1910 to 1980. Later, we proceed to obtain population forecasts using alternative modeling strategies and comment on the potential problems that the new demographic situation may have for future public policy."
