细颗粒物(PM_(2.5))对农村环境空气质量评价的影响分析

为了评估细颗粒物(PM2.5)监测对农村空气质量等级的影响,2014年在3个村庄监测了二氧化硫(SO2)、二氧化氮(NO2)、吸入性颗粒(PM10)和细颗粒物(PM2.5)等污染指标,使用环境空气质量标准(GB 3095-2012)和环境空气质量指数(AQI)法进行评价。结果显示:农村环境空气质量评价等级在细颗粒物(PM2.5)纳入评估后有所降低,等级为优的比例从29.7%下降到1.7%,等级为良的比例从70.3%提高到95.0%,同时轻微污染的比例从0提高到3.3%。环境空气质量指数(AQI)法对空气污染物有了更准确的评价,能评估未超标情况下空气污染物对空气质量的贡献程度。PM2.5与PM10有显著的正相关关系。     

Calculating the Return on Investment (ROI) for Library Consortia

This column focuses on formal collaboration and networking among libraries through consortia. It offers in-depth examinations of issues facing modern library consortia including (but not limited to) e-resource licensing, ebooks, next generation integrated library systems, shared print archiving, shared digital repositories, governance and other relevant topics. Contributions are accepted for this column and must be submitted to George Machovec (george@coalliance.org). Contact the column editor for suggested topics, deadlines and formatting.

Library consortia are under increasing scrutiny regarding their value to member libraries. Most consortia offer a suite of services which can be valued either quantitatively or qualitatively to determine a return on investment for money and time put into consortial activities. Various common consortial activities are discussed with thoughts regarding their value to local libraries. Recommendations and suggestions are provided on how to perform a Cost Benefit Analysis (CBA)/Return on Investment (ROI).     

Building Your Licensing and Negotiation Skills Toolkit

Licensing and the negotiating of electronic resources can be a daunting task for librarians who lack the proper skill sets and are unfamiliar with the intricacies of publisher agreements. Claire Dygert broke down the individual elements of a standard licensing agreement and explained the importance of protecting the rights of libraries. By providing insight from her years of experience, librarians learned how to develop a support network, build confidence, and be more effective negotiators.     

Hybrid Journals: Ensuring Systematic and Standard Discoverability of the Latest Open Access Articles

An important current challenge for research information providers is ensuring the automated discovery of Open Access (OA) content in hybrid journals. We found no evidence of discovery services that are able to systematically identify the crucially important free full-text availability of OA articles regardless of where and how such articles have been published (i.e., in fully OA journals or in hybrid journals). A solution is important because hybrid journals are proliferating and consequently the chances of missing OA articles is real and is happening. Nearly all of the major publishers now provide such journals in order to take advantage of recent changes in research funder requirements, and to be competitive in the new OA business model. By working with a group of scholarly publisher partners and by using standard metadata elements that publishers are already familiar with, we show a systematic and standardized manner to identify OA at the article level. Our proposal is to embed OA-related elements in the metadata freely exposed by publishers for aggregators and discovery services. For example, in the Table of Content (TOC) Really Simple Syndication feeds the publishers use to announce new journal issues and content. Based on the initial results obtained, we discuss the capabilities of our solution, and evaluate the impact produced by our application in the systematic discoverability of OA content from the participating hybrid journals, using an implementation done with the freely available journal current awareness service—JournalTOCs.     

The Impact of Reorganization of Staff Using the Core Competencies as a Framework for Staff Training and Development

In 2012, the Colorado State University Libraries’ Technical Services Department reorganized, which provided the catalyst to reconfigure paraprofessional staff positions. Staff are either part of the state classified system or are considered administrative professionals; both categories dictate the extent to which positions can be expanded to encompass assisting with managing electronic resources. This presentation is an account of how NASIG’s Core Competencies for Electronic Resource Librarians are scalable to be used in restructuring staff positions that assist with managing resources. Special attention will be paid to various modes of training that enable paraprofessionals to learn processes associated with electronic resources work.     

Actions and Updates on the Standards and Best Practices Front

Four standards and best practices recently released or currently underway at the National Information Standards Organization were presented: Knowledge Bases and Related Tools, Presentation and Identification of E-Journals, Open Discovery Initiative, and Open Access Metadata Indicators. Basics outlining the creation work and deliverables were shared for each project. Applicability of these standards and best practices for different stakeholders of the information community were discussed.     

The Unbearable Insecurity of the Electronic Resources Librarian

The article will outline the Core Competencies for Electronic Resources Librarians (NASIG Core Competencies Task Force [July 2013]) and intersect them with the practical everyday working experiences of an e-resources and periodicals librarian. The aim of the article is to convey an understanding of working in a practical library office environment, while being aware of the complexity of the theoretical competencies that are desirable and recommended. While it is aimed mainly at librarians, it should also be of interest to publishers and other vendors as they gain an understanding of what it is that librarians (their customers) do all day.     

Planning for the Budget-ocalypse: The Evolution of a Serials/ER Cancellation Methodology

The University of North Texas (UNT) Libraries are funded almost entirely by undergraduate student use fees. As the undergraduate enrollment has plateaued in recent years, the libraries have not been able to keep up with rising costs, resulting in a series of cuts to the materials budget totaling around $3.25 million. While some of these cuts took the form of reductions in firm orders and dissolution of approval plans, for the past three years the bulk has come from cancellations of serials and electronic resources. With each year’s cuts, the UNT Collection Development department has been forced to modify and refine their deselection process. This article will show the development of UNT’s strategy for determining cancellations using a variety of methods (overlap analysis, usage statistics, faculty input) and tools (EBSCO Usage Consolidation, Serials Solutions 360).     

Techniques for Tracking Perpetual Access

Tracking perpetual access entitlements is a challenging task that is too often simply ignored. Here, the presenter makes the case for the importance of systematically tracking perpetual access and outlines the information that is necessary to record. The presenter also draws on the literature and conversations with ten librarians working on the issue to provide a set of techniques for this task. These techniques incorporate several different systems common to academic libraries and include scenarios that illustrate the use in common situations.
