The engineering profession of the world can be expected to give more attention to the animal-plant food cycles in the years ahead and to determine new methods of preserving for complete utilization the critical and exhaustible supplies of plant foods for the generations yet to live. Coincidentally with this obligation which the engineer must assume, there is the romantic but very real task ahead of applying the same intensive interest in the ultimate preservation of foods as the agriculturists have displayed in producing them. The food preservation arts and sciences have now progressed forward far enough that the engineering profession can well assure the world that diets can henceforth be determined on the basis of what is good for man. With the coordination of our implements of electrical power, internal-combustion engine, propelled transportation, excellent network of road. ways and mechanical inventions, and with the competent support of the food technologists, the bacteriologists and the chemists, the engineering profession should be able to assure the multitudes that the world's ability to preserve is now prepared to equal the world's capacity to produce food. When complete coordination is effected, and production, preservation and distribution become daily realities, then the profession will have reached new heights in engineering, achievement, statesmanship and service. 相似文献

Within a relatively short geological time frame, Neolithic man, or more probably woman, domesticated all the major cereal grains, legumes, and root crops that the world's people depend on for most of their calories and protein. Until very recently, crop improvement was in the hands of farmers. The cornerstones of modern plant breeding were laid by Darwin and Mendel in the late 19th century. As the knowledge of genetics, plant pathology, and entomology have grown during the 20th century, plant breeders have made enormous contributions to increased food production throughout the world. There have been major plant breeding break-throughs for maize and wheat, and promising research activities to raise yields in marginal production environments are ongoing. Since it is doubtful that significant production benefits will soon be forthcoming from the use of genetic engineering techniques with higher plants, especially polyploid species, most research funds for crop improvement should continue to be allocated for conventional plant breeding research. 相似文献

The imponderable now is time. Certainly, it is in short supply if we hope to improve the world's prospects for food production. The requisite scientific skills that can contribute to greater world agricultural production exist in a uniquely concentrated form in the U.S. universities. Incentives for increased university involvement in technical assistance created by the International Development and Food Assistance Act of 1975 will not become effective until a mechanism which guarantees adequate and long-term funding is established. A continuing dialogue to define the nature and scope of needed reforms is necessary if maximum involvement of U.S. scientists in agricultural technical assistance is to be realized. Such involvement is vital in meeting the food needs of the developing world. 相似文献

Changing man 总被引：1，自引：0，他引：1

The human condition is changing both culturally and biologically. Although the cultural evolution overshadows the biological, the two are connected by feedback relationships; culture has a biological foundation. Natural selection continues to operate in modern mankind, but its action ought to be supplemented by artificial selection. The problems of the management of human evolution are, however, as much sociological as they are biological. The success of any eugenical program depends on the creation of favorable conditions for human development and self-actualization. In particular, the urgency of the problem of uncontrolled overpopulation exceeds at present that of genetic improvement. Contrary to the alarmist views of some biologists, the evolutionary perspectives for the human species may be regarded as favorable, although, of course, subject to improvement. Man should be the maker of his history, including his evolutionary history. The trend toward increasing social mobility and equality of opportunity may have desirable genetic effects because of the positive assortative mating which it encourages. It makes possible the realization of many hitherto concealed genetically conditioned talents and aptitudes. Rapid progress of both molecular and organismic, Cartesian and Darwinian, biology gives hope of development of new and powerful methods of genetic engineering, control of gene action, betterment of the environment, and improved understanding of the evolutionary processes in the living world, including man. 相似文献

本文以十六世纪前后英国历史转变的情况入手,从经济、政治和文艺的关系,说明了文艺复兴的时代背景及人文主义的产生。莎士比亚在这一时代背景和人文主义的影响下,写出了他的不朽名著《哈姆雷特》一剧。哈姆雷特这一人文主义的典型人物,在莎氏的笔下,把复仇和实现理想结合起来,从受到一系列严重打击而“垮”了的情况下,最后报了杀父之仇。本文分析指出了《哈姆雷特》之所以是个悲剧的主要点是在于主人翁没有完成他最高的理想:重整脱了节的时代,建立起他理想的社会。其原因是时代和哈姆雷特思想和地位的局限。他没有也不可能与人民群众一起,铲除邪恶,实现他人文主义的理想。 相似文献

I suggest that the teacher who wants to indoctrinate his students in the traditional role of the scientist as a neutral fact finder should not use historical materials of the kind now being prepared by historians of science: they will not serve his purposes. He may wish to follow the advice of philosopher J. C. C. Smart, who recently suggested that it is legitimate to use fictionalized history of science to illustrate one's pronouncements on scientific method (56). On the other hand, those teachers who want to counteract the dogmatism of the textbooks and convey some understanding of science as an activity that cannot be divorced from metaphysical or esthetic considerations may find some stimulation in the new history of science. As historian D. S. L. Cardwell has argued (57, p. 120): . . . [I]f the history of science is to be used as an educational discipline, to inculcate an enlightened and critical mind, then the Whig view . . . cannot do this. For it must emphasize the continuities, the smooth and successive developments from one great achievement to the next and so on; and in doing so it must automatically endow the present state of science with all the immense authority of history. He suggests that the critical mind might be inhibited by seeing the present as the inevitable, triumphant product of the past. The history of science could aid the teaching of science by showing that "such puzzling concepts as force, energy, etc., are man-made and were evolved in an understandable sequence in response to acutely felt and very real problems. They were not handed down by some celestial textbook writer to whom they were immediately self-evident" (57, p. 120). The past may give some hints on how to survive the most recent recurrence of public hostility to science. Rather than blaming historians such as Kuhn for encouraging antiscientific attitudes, as one physicist did in a public address in 1972 (58), one might consider this criticism of the older style of science history, published in 1940 by W. James Lyons (59, p. 381): The historians of science are responsible, it would appear, for the unpopularity of science among those most acutely affected by the depression. In their clamor to enhance the scientific tradition, and hoard for science all credit for the remarkable and unprecedented material advances which studded the century and a quarter preceding 1930, these historians have been more enthusiastic than accurate . . . science emerged [in the popular mind] as the most prominent force responsible for making this modern world so startlingly different from all preceding ages. Thus when, for many people, the modern world, in spite of all its resources, began to slip from its role of "best of all imaginable worlds," science came in for a proportionate share of blame. Had a more accurate picture of the part science has played been presented, science would not now be the object of so much suspicion and resentment. In more recent times, hostility to science has been intensified by the image of the "objective," robot-like scientist lacking emotions and moral values. If the new approach to the history of science really does give a more realistic picture of the behavior of scientists, perhaps it has a "redeeming social significance." Then, rather than limiting the conception of science to the strict pattern allowed by traditional local standards, one might try to change those standards in such a way as to reflect the freedom that the boldest natural philosophers have always exercised. 相似文献

The key parameters to technological growth have been identified as societal resources and societal expectations. Both of these are evident functions of technology, and their combined effects can be expected to continue technology's historical exponential growth. This growth pattern would be substantially altered only if we assume that knowledge is bounded or if society makes a conscious decision to stop the flow of resources into the production of new technological options. Although such conscious selection among individual technical fields is to be expected, it is very unlikely to apply to the totality of technology since, as society grows more complex it continuously creates new needs (priority factor), which in turn provide new opportunities for the application of technological options (payoff factor). The analysis also clearly emphasizes the important role which awareness of new technologies plays in forming societal expectations. These considerations indicate that the technological component of the world simulation model proposed by Meadows et al. (1) and Forrester (2) is best represented by an exponential growth function. The importance of this has been shown by Boyd (3) (Fig. 1), whose "technological optimist" curve has slightly less than exponential growth. Private comnmunication with Boyd indicates that an exponential assumption would reduce the time for equilibrium by several decades. Boyd also indicated that in his modification of the world dynamics model, an exponential technological growth would eventually dominate all other parameters in determining the long-term approach to a steady state. It is evident that the behavior of any world system model is very sensitive to the growth and interaction assumptions for its principal parameters. Thus, model studies should not be easily presumed to represent reality. The one conclusion that appears to be valid regardless of approach is the evident merit of reducing population growth. The parameter for quality of life shown in Fig. 1, parts 2 and 5, is the product of material levels, overcrowding, food, and pollution. The one factor that a "technological optimist" cannot expect to substantially alter in this model is the effect of overcrowding (Fig. 1, parts 3 and 6). Certainly, the many clear values of reducing population growth and improving the environment do not appear to require the justification of a world system analysis. In like manner, it seems appropriate to encourage the "technological optimist" to provide future options for societal choice, even though there may be present philosophical uncertainties as to their eventual merits. Unlike resources found in nature, technology is a manmade resource whose abundance can be continuously increased, and whose importance in determining the world's future is also increasing. 相似文献
