图书馆精神研究综论与若干基本问题的思考--"图书馆精神跨学科历史思考"系列论文之一

图书馆精神与人类的进取精神相一致，是图书馆的本质在人类社会精神形态领域的体现，是在一定社会和历史条件下，人类社会基于对图书馆本质的认识而形成的反映一定图书馆行业观和图书馆价值观的精神形态，是图书馆发挥其社会职能和历史贡献的内在动力。本文分别从图书馆学基础理论研究和人类文明的历史发展两个角度，对这一问题的研究进展进行了简明的综述，对这一问题研究的深化进行了跨学科的系统思考。

Analysis of Statistical Question Classification for Fact-Based Questions

Question classification systems play an important role in question answering systems and can be used in a wide range of other domains. The goal of question classification is to accurately assign labels to questions based on expected answer type. Most approaches in the past have relied on matching questions against hand-crafted rules. However, rules require laborious effort to create and often suffer from being too specific. Statistical question classification methods overcome these issues by employing machine learning techniques. We empirically show that a statistical approach is robust and achieves good performance on three diverse data sets with little or no hand tuning. Furthermore, we examine the role different syntactic and semantic features have on performance. We find that semantic features tend to increase performance more than purely syntactic features. Finally, we analyze common causes of misclassification error and provide insight into ways they may be overcome.     

工程服务中心:构建工程创新实践教育的支撑体系——上海交通大学国家双创示范基地案例分析

在高等工程教育中学生自主实践创新教学活动极为重要,而当前高校普遍缺乏创新支撑服务平台及灵活的实践服务模式,学生在自主开展实践教学活动时常常需耗费大量的时间和成本去完成创新项目所需资源的准备;一轮轮的教学实践环境建设,由于多围绕课程、学科的培养体系投入,造成设备利用率低,与学生强烈的创新实践需求形成尖锐矛盾。本文基于当前国家双创示范基地中学生创新中心建设,创造性提出以工具借出、设备借用、远程加工、设计IP撮合等为特点的特色服务模式,持续大量地为学生提供基本器具资源使用和加工服务。围绕学生需求提供"创新实践图书馆"式的服务,为学生创造创新实践的服务环境。本文就设备借出、3D打印等具体工程服务分中心建设的内容、目标和服务模式,阐述了这类创新实践服务中心的建设模式,需要解决的问题和实施思路。实践证明,建设工程服务中心能有效解决设备利用率问题,更好地培养大规模勇于投身实践的创新人才,为高校创新人才培养模式开辟新途径。     

Sustainability of independent community archives in China: a case study

There are three models for community archives in China. The first one is where community archives are kept in government-funded/government-established museums or archives. The second is where community archives are kept by scholarly organizations such as universities. The third involves the community establishing its own archive. This last model is very unusual in China. The PiCun Culture and Art Museum of Migrant Labor (PCMML) provides an example of this model as it is the only independent community archives focusing on migrant workers in China. This paper explores the emergence and development of PCMML, its impact on community members and challenges faced including funding and staffing, but also those unique to China—PCMML is greatly influenced by a range of national and local government policies and regulations. Conclusions are that survival strategies for independent community archives in China are dependent on three dimensions: the community itself, society and the government. Cultural consciousness of the community is the premise for the establishment and sustainability of independent community archives, and independent community archives can be the public space to cultivate cultural consciousness of community members and thus activates community members’ agency to document, preserve and disseminate their own history. At the same time, independent community archives also need to engage with broader society to avoid involution and gain support and understanding. Independent community archives are constrained by government policies and regulations, so it is essential for them to develop strategic relationships with government.     

An Investigation of Textbook Vetting and Evaluation Process in Tanzania

Textbook vetting and evaluation process intends to ensure that the materials provided are relevant, of the required quality, suitable ad would enhance learning efficiency and effectiveness. The paper investigates the role of publishers and Tanzania Institute of Education (TIE) in the textbooks vetting and evaluation process; examines factors used to vet, evaluate and approve primary and secondary school textbooks in Tanzania and proposes Strategies that would enhance the textbook vetting, evaluation and process. The study used a mixed method research design. Respondents were selected educational publishers; MoEVT, Baraza la Kiswahili Tanzania, TIE, and Publishers Association of Tanzania. Questionnaire and semi- structured interview were used to collect data which were analysed qualitatively and quantitatively. Major findings of the study were; textbooks vetting and evaluation process is not professionally conducted although standard criteria have been established; there is not well established roles among key players involved in the vetting and evaluation process leading to conflict of interest between TIE and the publishers. The study recommends establishing an independent professional evaluation board and a well-defined timetable and effective communication among various players; enacting a book policy and adopting a limited multiple-textbook publishing system.
