Exploring and modelling elements of information management that contribute towards making positive impacts: An outcome based approach for senior managers in a local government setting

This paper reports on the first stage of an investigation into monitoring and evaluating the impact of information management (IM) within a local government context. The overall study will utilise a combination of principles from various results-based, outcomes-based and social change approaches (Logical Framework Analysis, Most Significant Change, and Outcomes Mapping) in an attempt to move Leicestershire County Council away from a culture focused on traditional performance measurement, i.e. percentage change in use of services provided to the public, to something of real value. Interviews with 20 senior managers highlighted the important IM issues for Leicestershire County Council as a local government. These initial findings showed that maintaining high quality, trusted, and governed information and knowledge resources were of great value to the organisation. Analysis showed that 85% of senior managers interviewed considered IM to be “critical” in the achievement of organisational outcomes. Further analysis enabled the development of an initial framework indicating key areas where IM can have impact. These key areas will become the focus of further research, where applying a combination of approaches aforementioned will define the boundary partners, their specific outcomes and progress markers with possible impacts proposed. This detail will help to develop a framework for measuring the impact of IM.     

从教育测量走向教育评价——论新课程改革后高考考试评价制度改革的趋向

我国近三十年来的高考考试评价制度基本上是立足于对学生的教育测量,随着高中新课程的开展和对教育评价研究的深入,当前的高考考试评价改革应该从教育测量向教育评价转变。本文从理论上论证这种转变的合理性和必要性,总结了我国部分省市区在推行把综合素质评价列入高考招生内容的做法,并对下一步的改革措施提供了具体的建议。     

信息社会统计——一门正在形成的新学科

信息社会统计的研究,目前主要有几种视角所对应的理论:长波理论和相应的信息技术——经济范型,S曲线,社会指标理论。它面临着信息技术统计、信息经济统计和信息社会统计的挑战。应从学科建制角度加强"信息社会统计"研究,建立其理论基础,建立新的统计概念指标类型和综合测度。参考文献15。

教育权利：从机会均等到实现权利保障的平等——关于教育公平研究的综述

对教育公平的研究不外乎是关于教育公平所涉及到的受教育权利和实现机制的公平性及其评价的研究。具体为对受教育权利的研究,其中最为核心的就是对教育机会均等的研究;更进一步的就是对受教育权利或受教育机会均等的实现机制,即对教育资源配置公平的研究;再进一步就是对怎样评价这种受教育权利及其实现机制,即对教育（资源配置）公平测度的研究。     

Validation of a research-based student survey of instruction in a college of education

As a preparer of students for the profession of teaching, a college, school, or department of education in higher education has an expectation that instructors teach competently. In higher education, the student survey of instruction is one of the most important among other indicators of teaching effectiveness. This article presents a validation of a new student survey of instruction in a college of education. In this validation, we found the new survey to be as troublesome as the previous survey. Four major findings emerged from this study that offer hope for a new and improved survey of instructional effectiveness. These findings involve estimating reliability, subscore validity, course relevance and rigor of the instructor, and construct-irrelevant variables that threaten validity. Given the failed validation, many cogent observations provide guidance for the design and development of improved forms that may overcome these threats to validity and guide others in validating teaching effectiveness surveys.     

一种新颖的数字图像篡改检测方法

检测数字图像复制—粘贴型篡改是目前研究热点之一。多数复制—粘贴篡改检测方案只对刚性平移篡改具有较好的检测精度,无法有效应对更复杂的几何变换和常规信号攻击。为优化数字图像复制—粘贴篡改检测效率和精度,首次提出一种使用极坐标复指数变换（PCET）与一致性敏感哈希（CSH）的高效检测算法。首先,计算滑动窗口 PCET 系数,将其作为不变的图像局部特征|然后,根据这些特征,利用 CSH 算法快速、精确地匹配大量密集分块|最后,使用基于密集线性滤波的后处理算法消除匹配结果中的错误匹配并定位重复区域,得到最终检测结果。根据实验结果可知,该算法不仅检测精度平均提高 12.06%,而且处理时间平均缩短315.64s。因此利用对几何变换和常规信号攻击鲁棒的 PCET 系数刻画图像局部特征,并采用基于图像一致性的快速高精度匹配算法 CSH,可有效优化复制—粘贴篡改检测精度和效率。     

基于四阶累积量的CSPRIT算法

分析了基于二阶统计的CSPRIT算法在空间相关高斯噪声环境中存在的问题,提出将四阶累积量与CSPRIT算法相结合,处理一维二元相移键控信号（BPSK）和多元幅移键控信号（MASK）,实现信号到达角（DOA）的估计和波束形成器的构造。与基于二阶统计的CSPRIT算法相比,基于四阶累积量的改进算法能够有效抑制空间相关的高斯噪声,提高信号估计精度。计算机仿真验证了该算法的有效性。     

Developing science, technology and innovation indicators: What we can learn from the past

The science-technology-innovation system is one that is continuously and rapidly evolving. The dramatic growth over the last 20 years in the use of science, technology and innovation (STI) indicators appears first and foremost to be the result of a combination of, on the one hand, the ease of computerized access to an increasing number of measures of STI and, on the other hand, the interest in a growing number of public policy and private business circles in such indicators. Such growing interest might be expected in societies that increasingly use organised science and technology to achieve a wide variety of social and economic objectives and in which business competition is increasingly based on innovation. On the basis of 40 years of indicators work, we argue that frontiers and characteristics of STI indicators that were important last century may no longer be so relevant today and indeed may even be positively misleading.
