一种基于服务质量的网格服务发现机制

网格服务体系结构的出现对网格服务发现提出了挑战,UDDI上基于关键词和简单分类的服务发现机制已经不能很好满足需要.本文在分析现有相关研究的基础上,提出了基于服务质量的网格服务发现机制,引入服务质量相似度的概念,为网格服务发现提供了一种有效可行的方法.     

探讨影响机械加工精度的因素

零件从设计到生产过程中,加工环节对零件精度影响最大,而零件在机械加工过程中受到许多因素的影响。因此,严格控制零件的精度成为成品加工的一道重要工序。本文从人、机、料、法、环、测等几个因素分析影响机械加工工件精度的原因,以期能进一步提高零件的加工精度。     

基于学习共同体的中小学生学习心理机制及有效教学策略

学习共同体的学习方式有别于传统的教师主讲式的课堂授课形式。学习共同体特别强调"师-生"之间,"生-生"之间缔结一个相互联系、相互制约、彼此促进的共同体来完成学生的学习活动。基于学习共同体的中小学生学习心理机制是一种主动建构、信息加工的过程,即:"1.输入信息、注意保持、认知观念;2.加工信息、内化知识、建构系统;3.改组经验、解决问题、生成能力"。学习共同体旨在教师引导下,让学生通过自主探究、小组讨论、合作分享、获得知识、生成能力。教师实施有效的教学策略,充分发挥学习共同体的功能,会促进培养中小学生的核心素养,提升学生分析问题解决问题能力。     

Special educational needs in mainstream secondary school physical education: learning support assistants have their say

Learning support assistants (LSAs) gained more political and academic attention in Britain after Estelle Morris announced that schools of the future would include more trained staff to support learning to higher standards. LSAs, thus, should form an integral part of the culture of all school departments in Britain, including physical education (PE). The paper uses Antonio Gramsci's concept of hegemony to explore the processes and practices that shape the views and experiences of LSAs and ultimately the extent to which they facilitate an inclusive culture in PE. A web survey gathered the views and experiences of LSAs vis-à-vis the inclusion of pupils with special educational needs (SEN) in mainstream secondary school PE in North-West England. A modified version of the tailored design method participant contact strategy resulted in 343 LSAs starting the web survey, with 154 (45%) following it through to completion. All quantitative data were analysed using Microsoft Excel whilst qualitative data were subjected to thematic analysis. This entailed the identification of recurring themes and patterns present in the data. The findings highlight the hegemonic status of English, maths and science when it comes to the allocation of SEN resources, which most LSAs support and often reinforce. PE is particularly disadvantaged in this hierarchy of subject priority. The majority of LSAs have not received PE-specific training, which brings into question their ability to facilitate inclusion in PE. Moreover, many schools do not appear to value the involvement of LSAs in the planning of differentiated lessons, which could have a negative impact on the PE experiences of some pupils with SEN given that LSAs are perhaps most aware of the specific learning needs of the pupils they support.     

理学方法和唐诗批评的美学趣味

诗学理论中的"性情"说,发展到宋代,受到理学的深刻影响.北宋的中后期开始,理学思想及方法对于诗歌理论和诗学方法的渗透,儒家传统诗教中的"情动于中,而形于言"的内涵,因理学的观念和概念的提出而扩充了.其中首先是对"发乎情志"的界定.此时的"情志",已经不是原先单纯的出于自然的诗人个人情感,而是所谓合乎"天理"的"自然",这样,诗人的自然之情便要受到某种制约,而不是像先前那样,是随意的流泻.这里藏伏下来的因素,日后便成为后代诗学方法中,强调"性情"与"法度"统一的先兆.诗学理论与实践中,所谓的"自然"与"法度",或者"性情"与"法度"的统一,在"理"和"道"的层面上,根本无法实施,而只能落实到具体的诗歌技巧如"平仄"的运用中去.理学范畴中的矛盾最后导致诗歌创作实践中摹拟措施的产生.严羽及<沧浪诗话>中的许多观点的形成,都与宋代理学观念与方法有联系,而并非仅仅是"以禅喻诗".甚至可以说,严羽只是对前期深受理学方法影响的唐诗观的一次专业性总结.     

试论高校扩招后教学质量保障体系的构建

教育教学质量是高校工作永恒的主题。当前,在高等教育规模超常扩张的条件下,应从以下四方面构建教育教学质量的保障体系,确保教育教学质量的稳步提高;树立正确的教育质量观,建立健全教学制度机制,建立教学质量评估体系,加大教学设施建设力度。     

“中间代”或“中生代”：诗人自我意识的一种方式

对“中间代”或“中生代”的命名现象，其实只是这些诗人们“自我意识”的一种表现方式。他们对1990年代与1980年代的诗学差异尤为敏感，同时也就有对共同性的忽视，这导致了他们对自我存在的焦虑，并进而试图通过对自我命名的方式“标新立异”。然而“中间代”或“中生代”并不能构成一个独立于“第三代诗人”或“新生代”的“代”，他们应属于“新生代”的一部分或一种写作倾向，或者应称为“新生代后期诗人”。     

Reflectors as online extraverts?

Increasingly, online learning is perceived as an effective method of instruction. Much recent educational research has focused on examining the purposes and situations for which online education is best suited. In this paper, students enrolled in two online courses are compared with their peers enrolled in equivalent classroom‐based courses to investigate aspects of the relationship between learning style and mode of delivery. Student satisfaction measures are taken from participants in both modes of delivery and compared with student learning style. Feedback from the ‘Reflector’ learning style demonstrates higher satisfaction levels with the online mode of delivery compared with their matched counterparts following equivalent classroom‐based courses. Therefore, whilst ‘Reflectors’ might be regarded as Introverts in the traditional classroom setting, the additional time for reflection offered by online delivery makes this group more likely to contribute to online discussion, report higher satisfaction levels and generally behave more like online Extraverts.
