In all parts of the world, the teaching of history, because of its important ideological dimension, tends to be influenced by social and political changes. The recent upheavals in South Africa have confronted the nation with so many new tasks that it is difficult to decide which of them should have priority. These tasks include the establishing of a new educational curriculum which, paradoxically, no longer includes the subject of history as such. Instead, history is subsumed under the human and social sciences. This article analyses the content of history text books from the primary level upwards and from the 1980s to the most recent publications. On this basis it attempts to assess the extent and limits of the changes within a political setting marked by a tension between the historic struggle for equality and justice and the constraints imposed by the functioning of a liberal economy within the context of the globalization of modern capitalism. The considerable changes in the content of these books seem to be based on two different theoretical models: the multicultural model embodied in the idea of the "rainbow nation"; and the notion of the universality of humanity, transcending the diversity of cultures and confirmed by the findings of archaeology. While these two models can be a basis on which to refute racial inequality, they are not used to combat other forms of inequality, in particular social inequality. 相似文献

A report is given of the investigation of the iodine content of oyster shells taken from the reefs found in the Gulf of Mexico. The pulverized shells as sold on the market contain 200 to 300 parts per billion of iodine. Water soluble and alcohol soluble iodides appear to be absent. The granulated undried shells contain 500 parts per billion of iodine. Apparently there is a loss of iodine due to the temperature at which the pulverized shells are dried. 相似文献

The Minnesota Teacher Attitude Inventory (MTAI) and the Sixteen Personality Factors Questionnaire (16PF) were administered to 395 undergraduate teachers-in-training. The MTAI and the 16PF were compared using canonical analysis. They contained three related factors accounting for 41% of their total variance. It was concluded that teachers' attitudes toward their pupils are determined in large part by measurable personality traits. 相似文献

The Fujian Agriculture and Forestry University-Nova Scotia Agricultural College (FAFU-NSAC) 2 + 2 undergraduate program initiated in 2003 is a model for creative collaboration between China and Canada in undergraduate education. This paper addresses the achievements of the program development and highlights the process for successful curriculum development in the joint program. The authors also discuss some issues and challenges related to the Chinese-Canadian experience in undergraduate education, and propose some recommendations for further collaborations including: enlarging the scale of qualified programs; proposing a systematic baseline to control the program at a macro-level; simplifying coordination procedures with foreign partners; and adjusting the emphasis of courses introduced by the cooperative partner from quantity to quality. 相似文献

Nomographs for determining the filter order of classical filters based on selectivity requirements are presented. The selectivities for a variety of standard classical filters are summarized in equation form and the general selectivity nomograph is constructed. The selectivity equations are then converted into nomograph form by applying the relationship between the transfer function and the response slope. Design examples are presented to demonstrate the usefulness of the selectivity nomographs. These nomographs can be used to gauge filter performance and combined with optimization techniques can yield superior classical filter designs. 相似文献

To evaluate Information Retrieval Systems on their effectiveness, evaluation programs such as TREC offer a rigorous methodology
as well as benchmark collections. Whatever the evaluation collection used, effectiveness is generally considered globally,
averaging the results over a set of information needs. As a result, the variability of system performance is hidden as the
similarities and differences from one system to another are averaged. Moreover, the topics on which a given system succeeds
or fails are left unknown. In this paper we propose an approach based on data analysis methods (correspondence analysis and
clustering) to discover correlations between systems and to find trends in topic/system correlations. We show that it is possible
to cluster topics and systems according to system performance on these topics, some system clusters being better on some topics.
Finally, we propose a new method to consider complementary systems as based on their performances which can be applied for
example in the case of repeated queries. We consider the system profile based on the similarity of the set of TREC topics
on which systems achieve similar levels of performance. We show that this method is effective when using the TREC ad hoc collection. 相似文献

The construction of nomographs for transitional classical filters is described. Gain functions of classical filters are related to filter requirements resulting in a formulation for the general gain nomograph. The transitional filters that are products of approximating polynomials are incorporated into the general gain nomograph resulting in transitional filter nomographs that are sums of the individual nomographs. Nomographs for transitional filters using alternative forms where poles are interpolated are also considered. The resulting nomographs allow for quick optimization of transitional filter frequency response in many cases. Design examples are submitted and discussed. The proposed transitional filter nomographs provide the engineer with increased insight into the selection of classical transitional filters with optimum frequency response. 相似文献

Problem-solving behavior of six novice subjects attempting to solve an electrostatics problem in second-semester calculus-based college physics was observed and recorded. Five of the subjects were characterized as “A” or “B” students and one subject as a “D” student in introductory college physics. Although the A or B subjects were able to arrive at a “correct” solution to the problem, they exhibited major misconceptions about the problem situation as well as minimal qualitative understanding of the problem situation. The A or B subjects were successful in identifying, either from memory or written notes, equations relevant to electrostatics, whereas the D subject was not. The implication of this study is that current instruction in introductory calculus-based college physics and the students' previous science learnings place a premium on acquisition of correct quantitative solutions at the expense of qualitative understanding of physics problem situations. 相似文献
