数字学术环境下学术图书馆发展新形态研究——以空间、资源和服务“三要素”为视角

[目的/意义]基于对学术图书馆空间发展、资源建设和用户服务发展历程的梳理,剖析其在数字学术环境下的发展现状,为学术图书馆的空间再造、资源与服务整合提供思路,为提升服务效能、提高核心竞争力和可持续发展能力提供参考。[方法/过程]首先,对数字学术及数字学术环境进行定义,阐释数字学术与学术图书馆的互动关系。接着,分析学术图书馆从IC、LC、KC到创客空间的演变过程及其特点,考察国内外数字学术空间的发展现状及其原因。然后,从图书馆资源数据化、关联数据化及开放共享两个角度呈现数字学术环境下图书馆的资源建设现状与特点。最后,选取信息素养服务、研究数据服务和出版服务作为数字学术环境下图书馆用户服务的新内容进行分析。[结果/结论]学术图书馆空间创意化、资源与服务多元化是图书馆整合功能、高效运转以实现自我发展和满足用户需求的体现,也是图书馆为应对数字技术、数字化环境带来的机遇与挑战所做出的积极回应。     

基于动态数据整合的学者影响力h指数趋势监测与分析

[目的/意义]很多学科服务机构已经把学科数据的定期分析和提供学科报告作为学科服务的重要手段,但这种学科数据分析报告服务仅具有周期性,并不能及时跟踪动态变化的学科数据。本研究的目的是以h指数分析为例,对学者影响力进行动态追踪和监测,探索一种基于动态数据整合的面向预测的新型学科服务模式。[方法/过程]通过对国内和国外两个研究团队h指数发展、逐年变化趋势进行文献计量分析,获取团队成员自有成果发表年以来逐年的论文数量及其引用数据,并计算累积被引次数,逐年提取h指数。[结果/结论]团队成员中h指数增长趋势轨迹各不相同,需结合各成员任职年限、h指数增长率等数据对其在团队中的作用进行判断,论文最后对不同的h指数变化趋势在科研管理中的作用进行总结和概括。

以“主体间互动”为焦点的课堂观察与评价——新课程背景下课堂教学评价三步曲

以新课程对课堂教学的新认识和要求为出发点,关注课堂教学作为师生“主体间互动”的对话交往过程,发展区别于传统模式的课堂教学评价的三步曲。新课程背景下的课堂教学评价以“双向互动”的课堂观察为起点,随后从新课程提出的关于有效的课堂教学的标准出发,重新厘定课堂教学综合评析的主要维度,并辅以课堂教学评价的反思,以充分强调评价与教学的整合,推进课堂教学有效性和最优化的功能,促成学生和教师的共同发展。     

Casting the assessment net wide: Capturing all student learning

North Georgia College and State University has joined a national effort to move away from the isolated approach to measuring student learning. Educators from three divisions offer their perspectives.     

From teaching from the heart to teaching with a heart: Segmenting filipino college students’ views of their teachers’ caring behavior and their orientations as cared-for individuals

Caring, as a universal human phenomenon, should permeate elementary, secondary and tertiary level instruction. The practice of teaching, especially at the tertiary level, is not only substantial and procedural but relational as well. To teach with a heart is the essence that makes teaching a form of caring. When teaching is viewed as a form of caring, teachers become relational geniuses in their own right. This study is an attempt to segment Filipino college students’ views (n=1000) of their teachers’ caring behavior and their orientations as cared-for individuals. The identified clusters of teacher roles that indicate caring behavior imply that acts of teaching become acts of caring depending on how the teachers, theefficient cause of education, perform their ordinary tasks in the context ofextraordinariness. Such extraordinariness spells out a big difference in the way teachers practice the so-calledsingle loop caring or caring visibility anddouble- loop caring or caring presence. The former refers to teaching from the heart while the latter pertains to teaching with a heart. Interestingly, the extent to which teachers’ caring behavior is felt and experienced by the students positively shapes their orientations as cared-for individuals.     

SOFC temperature evaluation based on an adaptive fuzzy controller

The operating temperature of a solid oxide fuel cell （SOFC） stack is a very important parameter to be controlled, which impacts the performance of the SOFC due to thermal cycling. In this paper, an adaptive fuzzy control method based on an affine nonlinear temperature model is developed to control the temperature of the SOFC within a specified range. Fuzzy logic systems are used to approximate nonlinear functions in the SOFC system and an adaptive technique is employed to construct the controller. Compared with the traditional fuzzy and proportion-integral-derivative （PID） control, the simulation results show that the designed adaptive fuzzy control method performed much better. So it is feasible to build an adaptive fuzzy controller for temperature control of the SOFC.
