1.WTO与中国:挑战和机遇并存近年来,中国已崛起为世界上发展最快的大国。预期2002年的GDP将增长7.5~8个百分点。以欧洲的视角来看,中国社会正受益于一大批受过高等教育的技艺精湛的人才,他们不畏变革,勇于创新,乐于接受新技术。在这片土地上,变革被真正地看作一个坚实的文化特征,这或许得益于古老的亚洲传统哲学。中国将接受入世的挑战。这或许是漫长和艰难的过程,但终将使中国在市场经验中受益。中国入世将为世界大国注入重要内容。2.WTO与中国传媒产业中国传媒业对世界的开放将是中国在今后的数年里面临的最大… 相似文献

Intrinsic Factors for Continued ERP Learning: A Precursor to Interdisciplinary ERP Curriculum Design
Kuanchin Chen Muhammad Razi Thomas Rienzo 《Decision Sciences Journal of Innovative Education》2011,9(2):149-176
Unilateral enterprise resource planning (ERP) curriculum improvements from the instructor's perspective are likely to generate only limited success. Understanding student motivations and beliefs with ERP systems is the missing link to effective ERP education. Relatively little attention in the ERP literature has been given to student learning associated with ERP experience, and almost none to factors influencing current and expected student beliefs and behaviors relative to ERP. The complexity of ERP systems demands that beliefs and behaviors be considered when planning ERP curricula. In the present study, the Theory of Planned Behavior was extended to examine students’ intentions to explore additional aspects of ERP after their class exercises. When considering all students, attitude and subjective norm had positive and significant effects on intentions to continue ERP learning. Subjective norm also affected attitude, and availability of support materials had a positive effect on subjective norm. Distinctive patterns are found for the construct relationships between student groups who valued ERP education (the engaged) and those who placed little or no value on ERP education (the undecided). Results from competing model analyses indicate that support materials influenced the engaged and undecided groups differently. Strategies for ERP curriculum design are provided. 相似文献

A study of students from a primary school and its local secondary school was conducted to investigate students' relative interests
in geology and biology during the years prior to Year 10. Students from Years 1, 3, 5, 7 and 9 were interviewed, using an
innovative interview technique, and results show that interest in both subjects appears to be fairly evenly distributed throughout
all years. This paper reports on the study conducted and illustrates the success of the interview technique developed to accommodate
all students, especially those from younger year levels.

Personal Review: Sources of sulfide in waste streams and current biotechnologies for its removal 总被引:6,自引:0,他引:6

Sulfide-containing waste streams are generated by a number of industries. It is emitted into the environment as dis- solved sulfide (S2- and HS-) in wastewaters and as H2S in waste gases. Due to its corrosive nature, biological hydrogen sulfide removal processes are being investigated to overcome the chemical and disposal costs associated with existing chemically based removal processes. The nitrogen and sulfur metabolism interacts at various levels of the wastewater treatment process. Hence, the sulfur cycle offers possibilities to integrate nitrogen removal in the treatment process, which needs to be further optimized by appropriate design of the reactor configuration, optimization of performance parameters, retention of biomass and optimization of biomass growth. The present paper reviews the biotechnological advances to remove sulfides from various environments. 相似文献

The purpose of this study was to estimate the optimal body size, limb-segment length, girth or breadth ratios for 100-m backstroke mean speed performance in young swimmers. Sixty-three young swimmers (boys [n = 30; age: 13.98 ± 0.58 years]; girls [n = 33; age: 13.02 ± 1.20 years]) participated in this study. To identify the optimal body size and body composition components associated with 100-m backstroke speed performance, we adopted a multiplicative allometric log-linear regression model, which was refined using backward elimination. The multiplicative allometric model exploring the association between 100-m backstroke mean speed performance and the different somatic measurements estimated that biological age, sitting height, leg length for the lower-limbs, and two girths (forearm and arm relaxed girth) are the key predictors. Stature and body mass did not contribute to the model, suggesting that the advantage of longer levers was limb-specific rather than a general whole-body advantage. In fact, it is only by adopting multiplicative allometric models that the abovementioned ratios could have been derived. These findings highlighted the importance of considering somatic characteristics of young backstroke swimmers and can help swimming coaches to classify their swimmers and enable them to suggest what might be the swimmers’ most appropriate stroke (talent identification). 相似文献
