伴随着高校后勤管理社会化的逐步深入 ,学生思想政治工作的阵地也发生了转移。但由于陈旧观念和思想误区的存在 ,高校的学生思想政治工作者未能在角色转换中及时调整。如何转变观念 ,明确定位 ,充分发挥宿舍文化在思想政治工作中的教育和导向作用 ,本文作了一些粗浅的探索     

Statistical Power of the Multiple Domain Latent Growth Model for Detecting Group Differences

The latent growth model (LGM) in structural equation modeling (SEM) may be extended to allow for the modeling of associations among multiple latent growth trajectories, resulting in a multiple domain latent growth model (MDLGM). While the MDLGM is conceived as a more powerful multivariate analysis technique, the examination of its methodological performance is very limited. Hence, the present study compared the power of the MDLGM with that of a set of univariate LGMs for detecting group differences in growth rates over time using a Monte Carlo study with a two-group and two-domain design. The results indicated that there were different scenarios where the power rates for the MDLGM were greater than that of the set of LGMs (and vice versa) due to a joint function of the two domains’ intercorrelation size and the group difference effect size.     

基于MDF-Nearest算法的轨迹隐私保护方法

传统轨迹匿名方法在匿名集生成时没有考虑用户多种特征属性,在信息攻击下无法有效保护真实位置;在轨迹形成方面因没有将余弦角度和轨迹间距离作为形成的依据,导致某些虚假轨迹无法有效保护真实轨迹。为改善以上问题,构建一种依据用户多重特征信息构建的匿名集以保证匿名有效性;采用协作用户的真实轨迹并计算相似性,从而生成虚假轨迹相似性高的MDF-Nearest算法。实验结果表明,该方法随着k值的变大与生成轨迹数量的增多,隐私保护效果逐渐改进;与传统k匿名方法相比,该算法时间开销降低41.7%,而隐私保护程度可提高至97.1%。因此该方法能以较低的时间开销,提供质量可靠的位置服务,保护用户信息。     

谈多重复句分析

多重复句分析主要包括两个方面内容 :一是结构层次的确定 ,二是逻辑关系的把握。无论哪一方面的分析 ,都应有规律可寻。抓住关联词语是解决问题的有效途径 ,看划开之后各部分是否具有相对完整性和换位后能否成立是检查层次划分正确与否的有效手段。     

The scholarship of teaching: A comparison of conceptions held by experts and regular academic staff

Over the past decade the scholarship ofteaching has received considerable attention inthe higher education literature as a reactionto the widely cited Carnegie Foundation'sreport ``Scholarship Reconsidered'; however, theconcept has remained devoid of a unifieddefinition. A recent Delphi study conductedwith a selective group of scholars whoseexpertise lies in the area of universityteaching and learning indicated the extent towhich these ``experts' agreed with each other onimportant features and unresolved issues theyassociate with the scholarship of teaching. Building on the results of the Delphi study,the present article discusses the results of asecond survey comparing these ``experts' 'conceptions with those of a larger group ofscholars whose expertise lies in a differentacademic field (``regular academic staff'), inorder to identify the similarities anddifferences in the conceptions of thescholarship of teaching held by each of the twogroups. While regular academic staff werefound to associate the scholarship of teachingmore with good or effectiveteaching ``experts' pointed to notions such aspeer review and scholarly standards. Thediscussion of the results focuses on the notionof consensus reached within and betweenthe two groups. It is argued that in order topromote changes in policy with respect to whatis to count as scholarship, identifying andreporting ``experts' ' conceptions, thoughclearly necessary for promoting moreenlightened discussions on the issue, willremain insufficient. Policy change in academeis more likely to ensue as a result of thewider academic community reaching consensus onthe meaning, and nature, of the scholarship ofteaching. The wider academic community includes``experts', as well as colleagues in departmentsand disciplinary associations. The articleconcludes by exploring the notion of consensusthrough the lens of critical social theory.     

Rethinking researcher–teacher roles and relationships in educational action research through the use of Nel Noddings’ ethics of care

ABSTRACT

Action research approaches have evolved out of a criticism of previous research traditions, where teachers have been seen as research objects, at risk of being marginalized. Such approaches have also arisen out of the view that teaching, learning, and educational research are interrelated. In action research, teachers are seen as professionals, raising their status to subjects, conducting own research. The research is carried out with or by people rather than on someone, which changes the roles and relationships. Ethical dilemmas can arise, especially evident in action research, where the distinctions between researcher and researched are blurred or removed altogether. This paper aims to explore the changing roles and relationships between researchers and teachers in action research through a philosophical analysis based on the writings of Nel Noddings, especially the concept of ethics of care. The analysis creates an opportunity for a rethinking of researcher–teacher roles, focusing on responsibility and knowledge as well as reciprocity and communication. Based on the author’s own action research experiences, various dilemmas are discussed. Obstacles to and opportunities for developing caring relationships between researchers and teachers will also be highlighted. The implications of the study include valuing both researcher and teacher expertise and learning to understand each other’s perspectives as well as giving tailored care. It is also vital to find strategies to contextualize and enact these views and beliefs within the researcher–teacher relationship. Neither researchers nor teachers will have total control over the process, as they stay open to each other’s perspectives and needs based on a caring relationship.

Nearest neighbor search algorithm based on multiple background grids for fluid simulation

The core of smoothed particle hydrodynamics (SPH) is the nearest neighbor search subroutine. In this paper, a nearest neighbor search algorithm which is based on multiple background grids and support variable smooth length is introduced. Through tested on lid driven cavity flow, it is clear that this method can provide high accuracy. Analysis and experiments have been made on its parallelism, and the results show that this method has better parallelism and with adding processors its accuracy become higher, thus it achieves that efficiency grows in pace with accuracy.

多元智能理论视域下钢琴教学价值取向

20世纪80年代,霍华德·加德纳(Howard Gardner)提出了多元智能理论(TheTheory ofMultiple Intelligences)。这一建立在生物学、心理学、人类学、哲学、教育学、社会学之上的新型智力理论所倡导的"智能多元化"的观点,打破了人们对于智能的惯性思维,在教育领域引起了极大反响。越来越多的各国教育工作者对这一理论进行了研究和实践。多元智能理论自20世纪80年代传入我国之后,对我国的教育尤其是音乐教育的改革提供了理论依据。钢琴教学作为音乐教育的分支,在多元智能理论的指导下,其价值取向在重塑钢琴教学价值目标,拓展钢琴教学内容价值基础,丰富钢琴教学方式的价值追求,凸显钢琴教学的全面性几方面产生了变化。
