Charles Perrow used the term “normal accidents” to characterize a type of catastrophic failure that resulted when complex,
tightly coupled production systems encountered a certain kind of anomalous event. These were events in which systems failures
interacted with one another in a way that could not be anticipated, and could not be easily understood and corrected. Systems
of the production of expert knowledge are increasingly becoming tightly coupled. Unlike classical science, which operated
with a long time horizon, many current forms of expert knowledge are directed at immediate solutions to complex problems.
These are prone to breakdowns like the kind discussed by Perrow. The example of the Homestake mine experiment shows that even
in modern physics complex systems can produce knowledge failures that last for decades. The concept of knowledge risk is introduced,
and used to characterize the risk of failure in such systems of knowledge production. 相似文献

It is commonplace to say that the modern economy is knowledge based but a moment’s reflection points to the vacuity of this notion. For all economies are knowledge based and could not be otherwise. The question is rather how is one kind of knowledge based economy to be distinguished from another? This essay proposes that the answer may lie in three directions: (1) in terms of the variety of knowledge that is engaged; (2) in terms of the processes by which the production of knowledge is organised, and its corollary the resources devoted to knowledge production and dissemination; and, (3) in terms of the purposes to which knowledge is put. In respect of each of these dimensions, the rise of the modern university as a custodian of knowledge in Western economy and society has been of central importance; but universities are not alone in this role, a wide range of other agencies, private firms, public research laboratories for instance play an important role in defining a knowledge economy and have done so increasingly since the turn of the nineteenth century—a first indication of the systemic dimensions of a modern knowledge economy. 相似文献

Why culture attracts and resists economic analysis 总被引:1,自引:0,他引:1
Gillian Doyle 《Journal of Cultural Economics》2010,34(4):245-259
The realm of arts and culture can be seen as ephemeral and ill-suited to the ‘intrusion’ of quantitative analysis. Yet, demand
amongst end-users for economic research into cultural and creative industries is stronger today than ever it has been in the
past. Oddly, culture seems to both attract and resist economic analysis. Drawing on an analysis of recent research findings
related to multi-platform strategies in the television industry, this article examines what is distinctive about economics
of culture, and it assesses the appeals but also the challenges associated with conducting scholarly research work in this
particular area. 相似文献

Students need practice in decision making and problem solving, and sociodrama can provide this practice in a safe, nonthreatening context. It helps them to become aware of the typical ways they solve problems, and it increases both social and personal awareness. It may promote acceptance, cooperation, and cohesiveness in the classroom. Students readily adapt to this kind of activity and find it both enjoyable and stimulating. It is recommended as a useful method in the classroom and guidance and counseling setting for helping students understand their own behavior and the behavior of others. 相似文献

Results of the Vocabulary, Reading Comprehension, and Mathematics Concepts subtests for third-, sixth-, and eighth-grade students who took Form 5 of the Iowa Tests of Basic Skills in the 1976 school year were analyzed for sex bias. Statistical significance was found for each subtest for all of the grade levels. Follow-up analyses considered skill classification, sex-stereotypicalness, and item location of the items contributing to the statistical significance. No trends for these factors were found within each grade level for the four subtests considered. For all subtests, fewer items are identified at the third-grade level than for sixth or eighth grade, and these items, in general, favored boys. For the older students, when items are found to function differently for boys and girls, nearly half favor each sex. On the whole, little evidence for sex bias was found for the four subtests and three grade levels examined. 相似文献

The study examined the relationship between play and selected demographic variables (sex and SES) and kindergartners' achievement in prereading, language, and writing. Play was observed and ranked according to Smilansky's cognitive play categories. Prereading and language achievement were measured by the Metropolitan Reading Readiness Test; writing achievement was measured by students' word writing fluency. Sixty-five kindergartners (37 male, 28 female) were tested and observed in the classrooms over a four-week period. Multiple regression and ANOVA procedures were employed to determine the extent to which play, SES, and sex predicted student achievement. Play was a significant predictor of success on all three measures of achievement (p < .01). SES and sex appeared to have little influence on the prediction of achievement. There were significant main effects due to play for all achievement variables (p < .001). Post hoc analyses indicated that dramatic play had the most significant impact on play (p < .05). Pedagogical implications are made. 相似文献
