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。     

基于云模型的电子商务网站潜力评测模型

从投资者的角度对电子商务网站潜力进行评测需要准确、完整、自然的表达。作为一种普适的定性定量转换模型，云模型在评价领域已得到一定程度的应用。在网站潜力评测指标的评价和各指标权重的确定上均引入云模型，有效地减弱了该类研究中人为确定的主观性和理论计算的强硬区分，使结果更接近没有明确分界的自然语言评价。

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.

探析如何改善高职院校图书馆读者服务工作

高职院校是我国高校体系的一个重要组成部分,高职院校图书馆担负着为本院校的教学和科研服务的重任,而读者服务工作是图书馆的工作的核心。高职院校图书馆由于客观和主观的原因,在读者服务中存在一些问题,这些问题如果不能妥善解决,就会影响图书馆的读者服务质量。本研究分析了高职院校图书馆在读者服务中存在的比较有代表性的问题,并根据问题出现的原因提出了相应的解决对策。     

Changes in productivity and profitability of wool-growing farms that follow recommendations from agricultural and veterinary studies

Objective To estimate the changes in productivity and profitability in a group of wool-growing farms as they adopted major recommendations from agricultural and veterinary studies.
Farms Four wool-growing farms in south western Victoria were selected from the clients of the Mackinnon Project, a farm consultancy service run from the University of Melbourne. Each farm had closely followed recommended procedures, kept comprehensive financial and physical records and had been clients for at least 5 years. The comparison group was the South Western Victoria Monitor Farm Project (SWVMFP), about 45 farms in the same region as the study farms that were monitored annually by Agriculture Victoria.
Procedure For a 7-year period, the financial and physical performance of both groups of farms was estimated. Stocking rate, wool production, gross farm income, farm operating costs, net farm income and return on assets were compared.
Results Mean gross farm income of the four study farms steadily rose from 86% of the average SWVMFP farm before the adoption of recommendations to an average of 155%. During the same period, net farm income rose from 70% to 207% of the average of the SWVMFP. Return on asset of the four farms rose irregularly from 26% to 145% of the average of the SWVMFP. Farm operating costs on the four farms were higher than for the SWVMFP group, but the ratio of costs remained relatively constant.
Conclusion The adoption of proven research results was associated with large increases in net farm income. An increase in gross income, rather than a reduction in costs was the main reason for this. Research results offer a way to increase the financial viability of wool-growing farmers, many of whom are currently unable to maintain their lifestyle, resources and infrastructure.     

从森林绿色核算看我国林业政策的优化

为了更好地为林业管理决策服务和为政策制定提供依据,该文在对国内外绿色核算研究综述的基础上,论述了绿色核算的概念,探讨了森林绿色核算的政策应用. 文章通过对我国2000、2004年的森林绿色核算研究结果的认真分析指出:2000—2004年,我国森林eaGDP(经环境调整的GDP)增加了0.11%,反映出林业对国民经济的贡献是不断增加的; 在我国森林环境服务、社会效益中,土壤保育、森林防护效益最大,固碳供养、水源涵养效益次之,森林游憩效益最小. 因此,在森林间接效益利用中,受益最大的是农业、水利、电力等部门,受益最小的是林业部门本身. 该文还对我国的森林绿色核算结果进行了政策优化分析,提出了加强政府对森林资源保护的直接管制和补偿,提供资助,加强森林资源保护的地方标准、法律的制定,促进林业人力资本的发展,明确产权等建议,以促进实现社会经济发展与森林资源增长的目标.      

微地形DEM的最佳点云密度选取

[目的]通过对微地形DEM的最佳点云密度进行分析研究,从中选取出最佳点云密度,以实现高效、快速获取地表微地形观测结果的目的,既可降低计算成本,又能够保证观测精度。[方法]通过对多个扫描测次的点云数据进行深入的研究,确定出针对该数据最佳DEM水平分辨率为4mm,对原数据进行7种等级的压缩生成对应的DEM。采用平均误差、中误差、标准差3种最常见的DEM精度指标对生成的DEM进行精度评价分析。[结果](1)在点云压缩程度15%时,随着点云密度的减小,平均误差基本没有变化,维持在极低的数值上;点云压缩程度15%时,平均误差随着点云密度的减小而迅速的增大。(2)在点云压缩程度10%时,随着点云密度的减小,标准差基本没有变化;点云压缩程度10%时,标准差随着点云密度的减小而迅速增大。(3)在点云压缩程度20%时,随着点云密度的减小,中误差基本没有变化,维持在极低的数值上;点云压缩程度20%时,中误差随着点云密度的减小而迅速的增大。[结论]对比验证分析结果表明,20%的点云压缩密度为生成微地形DEM最佳的点云密度。
