基于运营支撑系统的广电统筹综合运营

数字电视整体转换给广电运营商带来前所未有的历史机遇,＂三网融合＂政策为广电综合业务的开展拓展了更宽阔的途径。通过技术和政策的推动,广电运营商彻底改变了以往业务单一、经营粗放的困境。运营支撑系统由于其自身的灵活性和可扩展性,作为广电整体转换后,所有业务统一接入和管理的综合平台,在广电实际运营过程中扮演着越来越重要的角色。本文通过介绍现代广电运营支撑系统的基础＂eTOM模型＂和一个实际建设的案例,说明在实际运营中,系统所起到的重要作用。

Characterization of two-dimensional cellular automata over ternary fields

The set of papers [3], [4], [6] and [7] (Chattopadhyay et al., 1999; Dihidar and Choudhury, 2004; Khan et al., 1997, 1999) deals with the behavior of the uniform two-dimensional cellular automata over binary fields (Z₂). Some structural properties and precise mathematical models using matrix algebra over the field Z₂ are reported for characterizing the behavior of two-dimensional nearest neighborhood linear cellular automata with null and periodic boundary conditions [3], [4], [6] and [7] (Chattopadhyay et al., 1999; Dihidar and Choudhury, 2004; Khan et al., 1997, 1999). In this paper, we characterize two-dimensional linear cellular automata transformations by using matrix algebra built on Z₃. We analyze some results for two-dimensional CA with rule numbers 2460N and 2460P. Finally, we investigate the dimension of the kernel of two-dimensional cellular automata defined by the rule number 2460N.     

The case of EAI facilitating knowledge management integration in local government domain

Information Technology (IT) infrastructure integration and knowledge management (KM) share communal objectives e.g. to transform organisations into more effective and efficient, agile and innovative, and more responsive to market changes. Such an association when assimilates bona fide knowledge management philosophy, it offers the IT departments a headship opportunity for organisational transformation in correlation with the rest of the organisation. Despite more than a decade of active research and practice in this complex problem area, advocates still perceive that Local Government Authorities (LGAs) lack integrated IT infrastructures that have resulted in the generation of data inconsistencies and redundancies, inefficient knowledge exchange and reduction in service quality and delivery. In the recent years, several LGAs have implemented Enterprise Application Integration (EAI) solutions to integrate their IT infrastructure. However, on analysing the relevant research studies, it is noticeable that application of EAI has been practiced at a larger scale in the private domain but to limited scale in the public domain. The shortage of such research studies presents a knowledge gap that needs to be endorsed. This research adapts a Revised Model for Integration Layers (REAL). By adapting to this model, it is exemplified that EAI achieves integration at five layers namely: connectivity, transportation, transformation, process integration and knowledge integration. The methodology for validating this model included a qualitative analysis of data gathered from formal interviews, observations and archive documents guided by initial conceptual observations from the literature. The findings indicate that cases leading to data inconsistencies and replication can be prevented by integrating knowledge through EAI.

多元遥感影像数据融合研究

由于遥感数据越来越丰富,不同传感器获取的影像数据在几何、光谱和空间分辨率等方面存在着一定的局限性和差异性。全色波段和多光谱影像融合得到的影像,兼有全色波段的高空间分辨率和多光谱影像的高光谱分辨率特性,可以满足影像解译的需求,而且融合后更能突出影像的某些特征:如土地利用变化和森林覆盖的变化等等。本文主要是介绍遥感影像融合的基本原理、融合后影像的评定和分析,并且将以主成份影像融合、IHS变换与直方图匹配法的遥感影像融合,进行以南昌市部分地区Quickbird全色影像和多光谱影像的融合实验分析。     

欧亚一体化差异的历史考察

以欧盟为当前形态的欧洲一体化和以东盟为代表的亚洲一体化是当前区域国家协调与合作的典范,也是当代全球化趋势的时代表征。在全面审视欧盟与东盟一体化历史进程的基础上,从政治制度的相异、经济水平的悬殊、思想文化的迥异、领土争端的有无等方面,深入探究两者之间差异的致因,为当前我国合理应对其发展提供价值镜鉴。     

新时期“广东精神”融入地方高职德育的探讨

新时期"广东精神"是广东人民历史沉淀形成的重要精神财富。作为一种区域文化,它是地方高职学生生活学习的文化背景,也是他们德育认知的载体、情感认同的依托、行为塑造的关键。新时期"广东精神"融入高职德育是实现"幸福广东"愿景的需要,也是彰显高职院校的办学特色、增强学校核心竞争力的需要,对当前广东高校思想政治教育具有重要的意义。     

完善我国公务员引咎辞职制度的立法思考

公务员引咎辞职制度作为责任政府建设的重要内容之一,我国公务员引咎辞职尚未形成完整的法律体系。《公务员法》对引咎辞职制度的规定缺乏可操作性,使得政策性规定成为重要实施依据,需以立法形式完善《公务员法》相关规定及配套法律,明确其主体、条件、程序、引咎辞职后的人事安排、监督机制等内容,使其向程序性问责转变,并借鉴西方国家培养以责任意识、民主法制观念为核心的政治文化。
