遥感与地理信息系统:向空间信息综合处理的方向发展

近年来，由于城市与区域规划、自然资源管理、农业研究、地形制图以及地质勘探等地球相关学科的发展，时及时、准确的信息需求急剧增加。地理信息系统(GIS)是解决这个问题的一个较成熟的方法。该系统具有处理和显示的双重功能，可以进行有效的数据存贮和检索，还可以同’数字遥感数据相结合。但是，遥感数据和地理信息系统是基于不同的空间概念，二者的有效结合尚存在障碍。本文指出了所存在的主要问题及其解决方案。目前，在地形制图/数字高程模型(DEM)的自动提取、地图特征提取、空间分辫率的改善和城市及区域规划等领域，都有遥感和地理信息系统综合应用的范例。

一种基于机器学习提取多类视频关键帧的方法

提出了一种不局限于视频种类的关键帧提取方法。这种基于机器学习提取视频关键帧的方法能有效地提取视频的关键部分。与以往传统的抽取关键帧方法相比,此方法不是针对某一类视频而设计的。为验证此方法,首先应用GIST描述符提取每幅图像的GIST特征,然后一个类稀疏模型来判断每幅图像的重要程度,最后选择具有高可靠得分的图像帧作为视频的关键帧,提取的关键帧将用于总结视频的主要内容。该方法仅需要一个模型来完成提取关键帧的工作,而不必为每一类视频都训练一个新模型。     

ALTAR: achieving learning through action research

This paper describes a collaborative action research (AR) study that took place between a U.K. university and a large U.K. manufacturing organisation, Britvic Soft Drinks Ltd. The ALTAR (Achieving Learning Through Action Research) project involved a number of AR cycles involving participants at different levels of the collaborating organisation. Britvic was already in the process of adopting knowledge management (KM) software but it was recognised that they could better exploit KM technologies by undertaking the AR project described in the paper. The project involved developing academic theory into practical concepts that influenced actions in the organisation and fed back into the academic research. The ALTAR approach and findings are described in this paper and conclusions are drawn about the AR study and its implications for AR, KM and for the future study of organisational learning through AR. The conclusions of the work are of practical use to managers in a variety of organisations and will inform academic research into cognate disciplines using the AR process.

Chinese cryptography: The Chinese Nationalist Party and intelligence management, 1927–1949

This paper is the first scholarly attempt to examine the history of Chinese cryptography and the role it played in building the intelligence network of the Chinese Nationalist Party (KMT) from 1927 to 1949. Rather than investigating the institutional structure of intelligence, I focus on Chinese characters, the primary medium that made cryptology and intelligence possible. Given that the Chinese writing system is by nature nonalphabetic and thus noncipherable, how did cryptography work in Chinese? How did the state and its scientists reengineer Chinese characters for the purposes of secret communication? This paper argues that due to the Chinese writing system itself, Chinese cryptography was bound to the use of codebooks rather than ciphers; thus, “codebook management” was central to building intelligence networks in China.

The STAR system: an interactive pronunciation tutor for young children

Between 1990 and 1998, the Speech Research Unit at the Defence Evaluation and Research Agency (DERA), and Hereford and Worcester County Council Education Department, a U.K. local education authority, conducted research into the use of speech recognition technology in an interactive computer-based pronunciation tutor for 5–7 year-old primary school children. The goal of the project was to develop a robust, autonomous system that would enable a child to practice the pronunciation of a given set of words by speaking them to a computer, which provided immediate feedback on whether the pronunciation was acceptable. This paper describes the development of the underlying speech recognition technology, the prototype real-time system which was developed, and the results of pilot trials of the system in a U.K. primary school.     

Making ERPs work: accountants and the introduction of ERP systems

In the last 10 years, the majority of large companies have attempted to install Enterprise Resource Planning (ERP) systems, replacing functional systems with a standardised company-wide system. However, making an ERP system work, we contend, is more than an issue of technical expertise or social accommodation: it is an ongoing, dynamic interaction between the ERP system, different groups in an organisation and external groups, such as vendors, management consultants and shareholders. This paper builds this argument using the example of management accountants in the U.K. based on evidence from a survey and several case studies. Drawing on work by Scarbrough and Corbett, we apply and develop a model, the technology power loop, linking technology, the control of technology and expertise to explain issues of how ERP systems are made to work and how expert groups seek to influence this development. We show, using empirical evidence from a survey and several case studies, that the relationship of accountants and technologies such as ERPs has become increasingly intertwined, but accountants continue to use their position to reshape their professional expertise wherever possible. However, our evidence also shows that neglect in this area allows other groups to wrest control from management accountants and make ERPs work for themselves.
