Exploring Research Data Hosting at the HKUST Institutional Repository

Abstract

The profusion of data created by modern research has brought about increasing discussion on the practice of data management and the development of such infrastructure. Many universities and libraries are exploring how to address this issue using institutional repositories, the Hong Kong University of Science and Technology (HKUST) Library being one of them. As part of the exploration, the author conducted a case study of datasets at major institutional repositories. This paper visits the issues relating to data archiving, reports common practices of data treatment at institutional repositories, and presents a list of recommendations for experimenting data archiving at the HKUST Institutional Repository.     

Promoting the Visibility of Educational Research through an Institutional Repository

Established in 1994 through the amalgamation of several teacher training colleges, The Hong Kong Institute of Education (HKIEd) is the major multidisciplinary teacher education provider in the Hong Kong SAR. Despite this, the Institute does not have a particularly high research profile when compared with its peer institutions in Hong Kong and around the world. Its research publishing achieves modest exposure and impact in international educational research literature. The Institute has a goal to attain the title of a “university of education” and has identified an improvement in its research output and profile as critical to achieving this. In this context the HKIEd Library embarked on the redevelopment of its institutional repository, changing its direction from being an archive of institutional publications to one which brought together and offered access to the sum total of published output of the Institute since its foundation, in a deliberate effort to promote Institute research. This paper explores the particular approach taken by the Library to the development of the institutional repository, how the repository contributes directly to and aligns with the research strategies of the Institute, and the impact the Repository has had so far on improving the profile of research at HKIEd.

An Integrative View of the Institutional Repositories in Hong Kong: Strategies and Challenges

Abstract

This paper reports on the developmental strategies, challenges and directions of the institutional repositories of the higher educational institutions in Hong Kong. The study integrates the size, content, full text and public accessibility of these repositories. The paper also compares archived output with research output as registered by the Hong Kong University Grants Committee. Percentages of archived work are low for journal and conference papers, but moderate for graduate theses. These deposit rates reflect the differing institutional policies. In recognizing these challenges, the Hong Kong Open Access Committee has been formed to address regional issues in knowledge sharing.

扫描数据支持下CPI编制方法研究

 全球信息技术的迅猛发展,以及由此引发的统计部门源头数据信息化采改革,都对当前CPI价格数据采集提出了更高的要求。而扫描数据的出现,或许能够解决这一问题。与传统的人工价格采集方式相比,扫描数据在降低企业回答负担、减少人工采价而产生的测量误差等方面,有着显著的优势。但是,作为一种高频海量数据,扫描数据对现有的指数计算方法也提出了挑战。目前,各国利用扫描数据编制CPI的方法不尽相同,而新提出的RYGEKS指数可能会有更广阔的前景。笔者对上述方法进行了比较研究,以期为我国利用扫描数据编制CPI提供理论依据。     

数据资产核算研究

数据是数字经济时代重要的生产要素,但是目前国民经济核算体系并没有确认数据的资产属性,数据的价值被极大地忽略了。本文认为数据具有明确的所有权归属和经济收益性,因此具有资产属性,应当扩展国民经济核算体系的资产核算范围,将数据资产纳入资产核算。根据数据的产生过程和特点,本文认为应当以聚合数据作为数据资产识别的单位,确认数据的非生产资产属性。本文建议开展包括数据资产和数据开发资产在内的附属核算,就数据资产估价方法给出了一些建议,并指出了若干需要进一步研究的重要课题。     

The Value of South and Southeast Asian Studies Journal Rankings

Abstract

This article ranks South and Southeast Asian Studies journals along three categories—quality, efficiency, and impact. The ranking summarizes the results of a survey sent to an international sample of South and Southeast Asian Studies scholars. This study is valuable in three ways: as a decision making tool for the South and Southeast Asian Studies academic community, as an evaluation of methodology in journal ranking studies, and as a discussion of the value of journal rankings studies to assessment and evaluation in higher education generally.

统计信用与统计数据质量研究

 统计数据质量问题严重影响着政府决策和社会公信力。本文运用博弈论分析方法,分析了声誉资本大小、失信惩戒力度、报假收益及监督力度是影响统计数据失真的重要因素,证明了引入统计信用可以在有限的成本下防范数据失真,提出了完善统计信用惩戒制度是统计信用发挥作用的制度基础。     

大数据应用的质量控制

数据作为重要的数据资源存在,不论是其内在蕴含的信息价值还是其已经成为人类社会所需数据有机组成的客观事实,都迫使我们去不断加强对大数据的应用。然而,由于大数据作为信息技术应用的副产品,其复杂性、不确定性和涌现性决定了我们应用大数据并非易事,存在着很多质量上的问题,除了具有传统数据所有的质量问题外,还包括一些独特的新问题。为了更好地应用大数据,本文对如何进行大数据应用的质量控制进行了初步的研究。主要内容包括以下三个方面：一是对什么是大数据质量、受哪些因素影响、可能存在哪些质量问题进行了探讨;二是从做好理论准备、建立质量控制方案、重视对小数据研究、加强大数据管理、加强大数据人才培养和加强大数据法制建设六个方面,提出了大数据应用的质量控制的基本想法;三是对大数据应用中需要引起注意的几个方面进行了讨论,并结合例子进行了阐释。

非线性面板数据聚类方法研究

对于一类变量非线性相关的面板数据,现有的基于线性算法的面板数据聚类方法并不能准确地度量样本间的相似性,且聚类结果的可解释性低。综合考虑变量非线性相关问题及聚类结果可解释性问题,提出一种非线性面板数据的聚类方法,通过非线性核主成分算法实现对样本相似性的测度,并基于混合高斯模型进行样本概率聚类,实证表明该方法的有效性及其对聚类结果的可解释性有所提高。

大数据时代统计学重构研究中的几个热点问题

随着新兴科学技术的迅猛发展,我们目前正面临大数据时代。大数据是“未来的新兴石油”,它必将对未来的科技与社会经济的发展产生深远影响。认识大数据这个崭新的概念是一个逐步深化的过程,有必要将对其研究上升为国家意志,因为大数据将深刻影响人类的决策模式和社会经济的运行模式,将发展成为一个极具潜力新兴产业,最终成为解决中国社会经济、政治转型期的重要手段。 迄今为止,能借助的国内外文献不多,虽然国内很多研究工作者希望尽早进入相关的大数据研究领域,却无从下手。为此,本文前瞻性地介绍当今大数据统计学理论研究中的几个热点问题,以期能有更多的他人后续研究。     

周期性普查数据质量评估方法与适用性研究

从普查数据准确性检验到普查数据误差测量,有关周期性普查数据质量的评估研究随着人们对普查数据生产过程的认识而不断发展与完善,先后发展出包括人口统计分析、数据一致性检验、行政记录审核和事后质量抽查等技术思路,包含多种具体的评估方法。根据评估依据与普查系统的关系,这些评估方法可被归纳为内部评估、外部评估以及事后抽查等三种评估途径。通过对每种评估方法特点及其适用性的分析,有利于进一步深化我国周期性普查数据质量评估的理论研究。

数据修订、实时估计与时变参数货币政策规则抉择

本文拓展构建了后顾、同期和前瞻三种类型的货币政策规则,并基于实时数据和最终数据实证分析数据修订和实时估计对货币政策参数的影响效应。研究结果发现,数据修订对泰勒规则的影响取决于不同模型,而且在三种模型设定中,盯住产出缺口和通胀目标的时变参数均在不同程度上受数据修订的影响。特别是,对于最终数据,采用同期性货币政策规则展开估计最为有效;而对于实时数据,则基于后顾性货币政策规则模型估计是最佳的。最后,本文在数据选择和模型匹配上提出相应的对策建议。
