Correlation analysis-based image segmentation approach for automatic agriculture vehicle 总被引:1,自引:0,他引:1
INTRODUCTION In recent years,harvesting crop by combine has become more and more popular in China.In2003,combines were used to harvest23%of rice and71%of wheat.The work described here is part of a pro-ject aimed at researching automatic combines who follow the cut-uncut edge of the crops automatically to reduce the driver’s fatigue from the intensive work.Much attention has been focused on vision-bas-ed automatic agriculture vehicle.Image segmenta-tion is the key to extracting the guida… 相似文献

Formative assessment originated and developed in a Western context. With its function of learning improvement being evidenced in research, formative assessment has been adopted in assessment initiatives in multiple contexts including that of China. Research, however, reveals that formative assessment as implemented in Chinese contexts is by no means equivalent to what is understood and implemented in the West; rather, in many cases, it is decontextualised and recontextualised, or culturally appropriated. This paper presents findings of a study which examined the culturally appropriated representation of formative assessment within eight universities in a mid-western province of China. Senior administrators in each university were interviewed face-to-face and individually to fulfill three purposes: (1) To clarify understandings of formative assessment in the area of college English education; (2) To explore the existing gap between formative assessment principles and their representation in College English Curriculum Requirements (CECR), and the gap between formative assessment initiatives at the national level and local contexts; and (3) To distill implications for policy-borrowing and effective implementation in the Chinese context. 相似文献

社鼠、雷琼社鼠和针毛鼠都是山地栖息种类,它们染色体的2n数目和形态明显有别于同属的其他各种.体现出它们之间的亲缘关系较近,它们间的核型演化是通过罗伯逊易位和缺失途径,社鼠、雷琼社鼠和针毛鼠有着不同于属中其他种类的生态位,把它们另作一属会恰当些;社鼠和雷琼社鼠的地理分布有所不同.但染色体组型并不差异.认为它们间可能仅是毛色变异,而不存在两个亚种之分. 相似文献

独立学院师资建设问题探析 总被引:9,自引:0,他引:9
民办学校走内涵发展之路,要有一支较为稳定的、高质量的师资队伍,因而对教师管理的改革和研究变得尤为重要。民办师资管理的改革发展,既需要政府制定和执行利于民办教育发展的政策,创造良好的发展环境,也需要民办学校本身科学的经营和管理,这是一项繁琐而长期的工程。当然,只要社会、学校、教师各方面齐心协力,采取有力措施,按教育规律办事,最大限度地激发教师和工作人员的创造活力,我们有理由相信民办学校的内涵发展道路会走得更坚实和宽广。这也是刊发本专题的期望之所在。 相似文献

The article traces the origin and development of the concept of social skills in first and foremost American academic discourse. As soon as the concept of social skills was coined, the concern for people lacking such skills started and has been on the increase ever since (now sharing public attention with related concepts such as self-control, emotional intelligence and empathy). After the analysis of the academic history of the concept follows an examination of the implementation of a range of assessment instruments and training programmes related to social skills (and lack hereof) in contemporary Danish welfare institutions (more specifically, day nurseries and schools, employment and penal services). The analysis forwarded in the article thus demonstrates how an intellectual idea may develop and travel - and on its journey connect to pre-existing cultural logics and societal concerns. The idea of social skills has through its development been made uncontroversial – everybody wants to be skilful. The concept does, however, convey an individualistic view on social life and imposes a reflexivity over own performance on the participants. Further, its normative character contributes to a problematization of those who are perceived to lack these skills. 相似文献
