教育信息化应走开源软件之路

随着教育信息化的深入发展,人们发现教育软件开发与应用已经成为制约教育信息化发展的症结。开源软件不但能够胜任教育信息化的需求,降低成本,而且能够随时根据教学需要自主改进程序、促进教学水平和学生创新能力的提高。最后就教育信息化推广使用开源软件提出几点建议。     

商务汉语教材编写初探

随着中国加入 WTO,世界掀起了“汉语热”,可是我国的商务汉语教材却不能满足需要 ,本文就商务汉语教材编写中的一些问题进行了探讨。商务汉语教材的教学对象和教学目的具有特殊性。编写商务汉语教材不仅要遵循一般教材编写的原则 ,还要遵循交际性和开放性的原则。在教材的编写中要注意教学内容的选择和教材的体例设计等问题。     

妻妾成群中的人性抉择--试论《金瓶梅》对男性精神世界变异的反思及其意义

《金瓶梅》的作者借一个大家庭,来表现自己对衰世中人尤其是男性的精神状况的反思。书中描写的男权世界里的这些女性,只是作为男性精神世界的不同组成部分的一种象征,并不具有独立存在的意义。她们分别代表着人心的"理、欲、情、意、气",其冲突实质上是人的内心各种欲望的斗争。其斗争的结果也反映了在这样一个特定的时代里人的精神命运的走向。     

2008北京奥运会中国金牌赶超美国的可能性 —基于东道主效应的分析和预测

 2008年北京奥运会中国代表团能否在家门口实现金牌、奖牌数的新突破从而取代美国成为第一金牌大国，国人充满期待。文章提出了东道国效应的测算办法，利用GM(1,1)模型预测了中美两国可能获得的金牌总数。考虑到东道主效应，中国金牌数赶超美国几成定局。要理智对待金牌和奖牌，当好东道主，展现大国风貌。     

“Serials at Warp Speed: Navigating Transitions,” the 2007 North Carolina Serials Conference

Abstract

Reports on four major serials conferences, the 2007 North Carolina Serials Conference, the 2007 meeting of the Ohio Valley Group of Technical Services Librarians, the Canadian Library Association’s 2007 Pre-Conference, and the 2007 North American Serials Interest Group Conference.     

Leaning into Browser Extensions

abstract

An array of browser extensions has been developed to help researchers locate full-text content, whether that full text is available in an institutional repository, on a publishers site, or in an open access journal. Examples of such browser extensions include Unpaywall, Kopernio, EZproxy tools, and Lean Library. This Balance Point column focuses on the growth of browser extensions, the need they are filling, and their adoption by libraries. Particular attention is paid to the Lean Library browser extension and the services offered by Lean Library. Drawing on the literature and interviews with librarians in the field, the advantages and disadvantages of browser extensions are addressed, as well as security concerns.     

IFLA Library Reference Model,RDA, and Serials in a Nutshell

Abstract

IFLA Library Reference Model (IFLA LRM) represents the consolidation of Functional Requirements for Bibliographic Records (FRBR) and the two other conceptual models of the Functional Requirements (FR) family, the Functional Requirements for Authority Data (FRAD) and the Functional Requirements for Subject Authority Data (FRSAD). IFLA LRM includes a specific section (5.8) devoted to serials. The RDA Steering Committee adopted IFLA LRM as the conceptual model for the development of RDA in November 2016. The 3R (RDA Toolkit Restructure and Redesign) Project’s purpose is partly to make RDA compatible with the IFLA LRM. A beta version of the English-language content of the RDA Toolkit, which incorporates the IFLA LRM, was released in June 2018. This column explores, in lay terms, serials in relation to the IFLA LRM and the RDA Toolkit Restructure and Redesign (3R) Project. The beta version of the restructured and redesigned RDA Toolkit introduces several new concepts relating to serials.     

Determining Process Death Based on Censored Activity Data

This article addresses the problem of estimating the time of apparent death in a binary stochastic process. We show that, when only censored data are available, a fitted logistic regression model may estimate the time of death incorrectly. We improve this estimation by utilizing discrete-event simulation to produce simulated complete time series data. The proposed methodology may be applied to situations where time of death cannot be formally determined and has to be estimated based on prolonged inactivity. As an illustration, we use observed monthly activity patterns from 300 real Open Source Software development projects sampled from Sourceforge.net.     

Credit access,macroprudential rules and policy interventions: Lessons for potential first time buyers

Given the increased popularity of macroprudential measures in the aftermath of the great financial crisis (GFC), a key policy question to arise in certain mortgage markets is whether a significant access to credit issue exists amongst prospective homeowners because of these new policies. In this paper we assess whether such a problem arises in the context of the Irish mortgage market – a market particularly adversely impacted by the GFC. We use a microsimulation model to estimate the level of latent credit demand that could be serviced by the market given prudent credit risk assessment and the current macroprudential regulations. We then compare this demand to current market provision to explore whether a credit gap exists. Finally, we simulate how a public mortgage credit scheme or equity “help-to-buy” type instrument may help credit access. We find both instruments to be effective but would lead to somewhat higher house prices.     

Designing centralized waiting lists for attachment to a primary care provider: Considerations from a logic analysis

Access to a regular primary care provider is essential to quality care. In Canada, where 15 % of patients are unattached (i.e., without a regular provider), centralized waiting lists (CWLs) help attach patients to a primary care provider (family physician or nurse practitioner). Previous studies reveal mechanisms needed for CWLs to work, but focus mostly on CWLs for specialized health care. We aim to better understand how to design CWLs for unattached patients in primary care.In this study, a logic analysis compares empirical evidence from a qualitative case study of CWLs for unattached patients in seven Canadian provinces to programme theory derived from a realist review on CWLs. Data is analyzed using context-intervention-mechanism-outcome configurations.Results identify mechanisms involved in three components of CWL design: patient registration, patient prioritization, and patient assignment to a provider for attachment. CWL programme theory is revised to integrate mechanisms specific to primary care, where patients, rather than referring providers, are responsible for registering on the CWL, where prioritization must consider a broad range of conditions and characteristics, and where long-term acceptability of attachment is important. The study provides new insight into mechanisms that enable CWLs for unattached patients to work.
