数字图书馆服务环境的重塑

对数字图书馆服务环境重塑的必要性进行了阐述,并从四个方面对数字图书馆服务环境重塑进行了探讨与研究,希望能推动我国数字图书馆的发展。     

高校学科馆员服务模式探讨——以“藏、参、教—联3＋1”模式为例

将国内外高校学科馆员服务内容归纳为一种模式,即学科馆员＂藏、参、教—联3＋1＂模式。所谓＂藏＂,即馆藏建设;＂参＂,即参考咨询;＂教＂,即教育培训;＂联＂,即院系联系。阐述了该模式四个要素的意义及其相互之间的关系,并对普通高校实施学科馆员服务提出了建议。     

云计算环境下图书馆信息服务创新的基本路径

云计算正在推动图书馆信息服务变革,图书馆的云时代即将到来。通过创新发展环境、创新信息资源共建共享模式、创新图书馆业务流程、创新信息资源安全策略及创新图书馆信息服务队伍等,推动云计算环境下图书馆信息服务创新。     

移动信息服务在农村地区初始采纳的实证研究

建设社会主义新农村是我国政府的重要任务,而新农村建设的关键任务之一是推进具有信息化特征的现代农业。在农村地区信息化背景下,研究驱动农村用户采纳移动信息服务的主要因素。根据使用移动信息服务的内部动机和外部动机,主要研究娱乐、信息、社会互动、长期在线和方便性等5个因素并建立了模型。根据实证数据验证了模型,最后得到了一些重要结论,反映了农村地区在移动信息服务采纳中的现状,可为电信部门推广农村业务提供帮助。     

新世纪“图书馆有偿服务”研究综述

有偿服务一直是图书馆界的热门话题。综观新世纪以来关于"图书馆有偿服务"的研究脉络,其主要内容大致涵盖以下几大部分:"有偿服务的研究脉络与发展趋势"、"收费价格"、"收费管理"等。     

多元文化及其图书馆服务策略

阐述了多元文化的涵义、形成背景及其社会价值,论述了多元文化在世界范围内的发展趋势和我国当今社会注重开发、利用多元文化的必要性,提出了网络环境条件下的图书馆开展多元文化服务应采取的策略和具体措施。     

35技术在城市森林研究中的应用

总结国内外3s技术在城市森林研究领域应用现状，分析其不足，即遥感学家与植物生态学家缺乏沟通、被动遥感优势尚未挖掘、生态系统服务制图滞后、生态系统管理中忽视信息系统建设，以及景观规划的精确性与客观性有待提高等，在此基础上提出相应改进建议，以期为我国城市森林的3S技术应用和城市森林建设工作提供借鉴。     

National Evaluation of User Profiles in Aquaculture

One problem with information delivery to a specific segment of the agricultural community is identifying the characteristics and needs of the end-user. Such a profile could be used for evaluation of the products or services provided. The Aquaculture Information Center of the National Agricultural Library was able to construct to such a profile based on historical data as well as current assessments from several United States aquaculture information groups. Analysis of this data provided specific and general direction for future products and services within the aquaculture information community. Findings also highlighted the important need for further tracking of such data, emphasis on continued networking among information groups, and creation of formal guidelines for aquaculture information access for the end-user.     

Anthropogenic effects on the physical and chemical properties of subtropical coastal urban soils

We investigated the effects of various anthropogenic factors on urban soil properties in subtropical, coastal Tampa, FL, USA. Specifically, we explored the influence of (i) urbanization as measured by land use, land cover, population density and years since urban development and (ii) socioeconomic conditions as reflected in household income and property values on bulk density (BD) and several key soil chemical properties. Results indicate that Tampa’s urban soils were affected to varying degrees by these factors with chemical properties being more variable than BD. Across land uses significant differences were found for Mehlich‐1 (M1) extractable P, Ca and Na. A similar trend was observed for land‐cover classes, although significant differences were also found for pH and M1‐Cu. Soil properties had no statistically significant relationship with population density. However, time since urbanization did with M1‐P and Na varying significantly across age categories. For our socioeconomic analyses, M1‐K and Mg levels differed significantly by household income while pH, P, Ca and Na values differed significantly by property value. Overall, our findings indicate that despite their inherent heterogeneity, there are identifiable patterns among subtropical coastal urban soil properties. We suggest that a more thorough understanding of these patterns and their drivers is an essential first step towards developing soil management strategies aimed at maintaining environmental quality and ecosystem services in subtropical cities.
