浅议科学发展观对马克思主义人本思想的践行与发展

党的十六届三中全会所提出的：“坚持以人为本，树立全面、协调、可持续的发展观。促进经济社会和人的全面发展”的科学发展理念，是马克思主义人本思想在当代中国的具体实践，是我们党执政理念和治国理念的重大飞跃。     

Aggregating concept map data to investigate the knowledge of beginning CS students

Concept maps have a long history in educational settings as a tool for teaching, learning, and assessing. As an assessment tool, they are predominantly used to extract the structural configuration of learners’ knowledge. This article presents an investigation of the knowledge structures of a large group of beginning CS students. The investigation is based on a method that collects, aggregates, and automatically analyzes the concept maps of a group of learners as a whole, to identify common structural configurations and differences in the learners’ knowledge. It shows that those students who have attended CS education in their secondary school life have, on average, configured their knowledge about typical core CS/OOP concepts differently. Also, artifacts of their particular CS curriculum are visible in their externalized knowledge. The data structures and analysis methods necessary for working with concept landscapes have been implemented as a GNU R package that is freely available.     

Interactive sculpting of product shape based on constraint manipulation in virtual environment

In product concept design, not only designers with professional CAD skills, but also final customers take part in the design and evaluation of product shape styling. Because customers usually lack surface modelling background and are not familiar with concrete operations of commercial CAD systems, it is difficult for them to express their change intentions of product shape through professional CAD tools if they are not satisfied with the current shape design. This paper puts forward a method for creating, dragging and manipulating constraint and load represented in form of icon entity in interactive sculpting of product shape in virtual environment. The method supports customers manipulation of sculpting constraints or loads on sculpting shapes in virtual reality interaction to control the deformation of product shape. Constraints management based on icon entity is similar to spline lofting operation that is familiar to engineers, so users do not need to know surface details or have any professional knowledge of surface modelling, by only using their physical and engineering experience, they can manipulate the sculpting of product shape intuitively.     

对大学生成长小环境道德建设的探究与思考

社会主义荣辱观是马克思主义道德观的新发展,加强对大学生社会主义荣辱观教育不仅应当重视社会大环境建设,也要对大学生成长小环境道德建设问题进行探究与思考。小环境中如班级、宿舍、社团的道德文化尚存在一系列问题,解决这些问题需要高度重视,并以加强制度建设为核心。     

论毛泽东人民观的情感因素

毛泽东对人民的情感，业自他对中国社会以及人类历史的深刻了解；来自科学理论的指导；来自社会生活的切身体验和所处环境的直接影响；来自长期与革命斗争实践的探索和积累，来自他对人民江山的千秋伟业的倍加珍惜和全力维护。章对此作了较系统较详尽的阐述。

Resource discovery in distributed digital libraries through visual knowledge navigation

INTRODUCTION In this paper, we present our work in the Strand Map Service (SMS), which provides concept map based browsing interfaces for resource discovery in a library independent manner within American Na- tional Science Digital Library (NSDL). As critical components of digital libraries, dis- covery systems provide interfaces that support user to search and browse for resources in digital libraries (Hall et al., 1999). The effectiveness of discovery systems has big impact on the…
