"食品微生物学"是高等院校食品科学与工程、食品质量与安全及其相关专业的一门必修专业基础课,该课程实验技术是食品类专业学生必须掌握的基本技能,而传统的实验教学存在着与就业岗位需求脱节、学生参与度低等诸多问题,难以培养学生独立完成岗位工作的能力。为了培养学生的综合实践能力,适应就业岗位需求,保证该课程的实践教学质量,课题组通过调研30余家就业单位微生物岗位实际,将课程原有实验教学内容整合为两大综合性实验项目,涵盖了食品微生物学全部基本实验技能。实践表明,两大综合性实验项目的开展可有效提高食品微生物学实验教学效果,使学生全面获得食品微生物学的基本实验技能,有助于提高学生的综合能力,实现学生与就业岗位的无缝对接。 相似文献

The results of the last (in the thermonuclear program “Magnetic compression”) MAGO-IX experiment with a plasma chamber including a third compartment designed to compress plasma with a converging liner are presented. An X-ray pulse consisting of an intense peak of 1-μs duration, followed by a low-intensity tail with a duration of more than 10 μs, was recorded. In the MAGO-IX experiment, the neutrons were generated mainly in the third compartment. A neutron yield of 2 × 1012 was obtained. The results demonstrate that the expected compression of preheated plasma in chambers similar to MAGO-IX is promising for achieving thermonuclear ignition. 相似文献

The diffusion of medical technology is largely determined by the marketplace demands supported by national and historical
contexts. Using the cases of cesarean delivery and newborn intensive care in the United States, this article presents the
argument that the interaction of four factors accounts for the rapid diffusion of untested technologies. These factors are
economic expansion in an unrestricted market, the vulnerability of the patient population, a social disposition towards emergency
medicine, and the vested interest of medical specialists.
Jeanne Guillemin is a professor of sociology at Boston College. She served on the National Institutes of Health Consensus
Task Force on Cesarean Birth and authored the section of the task force’s 1981 report on international data on cesarean rates.
She is also the coauthor, with Lynda Lytle Holmstrom, ofMixed Blessings: Intensive Care for Newborns, which analyzes the national and international development of this hospital service, as well as authoring numerous articles
on medical policy. 相似文献

Many of you, reading the title of this report, probably felt a certain confusion about this new, unusual term natural experiment. To dispel this quite natural confusion, let me say immediately that I am proposing this term to designate special investigatory techniques situated somewhere between external, objective observation, on the one hand, and a man-devised laboratory experiment (at present referred to as a psychological experiment), on the other. These original techniques, different from both the first and the second, are actually not completely new and unusual but, on the contrary, are well known to every one of you in their rudimentary form. Considered in more detail, they might perhaps be of considerable interest both theoretically and practically. It is for this reason that I decided to propose a new term to designate them. One cannot, of course, in such a brief report attempt to outline all the possible applications of this method to all the phenomena to which it could be applied; hence, I shall focus on an area that is more familiar to me and, moreover, seems to be especially suited for conducting a natural experiment, namely, research on personality or individuality. 相似文献
