4美国图书馆的今天:实践、趋势与挑战显示文摘目前,美国的图书馆一般都订有策略性规划,有自己的人事分类体系,建立了内部切磋交流机制和组织机构,十分重视用户工作。其发展呈现如下一些趋势:越来越多地使用电子服务方式;注重书目的双重作用;大力开展远程教育和原文传递服务;推行馆舍联合使用和采编外包及联合购买,等等。不断变化的形势,也给美国的图书馆提出了新的挑战,如如何处理科技消费问题、经费预算不稳和馆员短缺问题、资源价格高居不下和网上色情问题,等等。柯素善 顾小明 徐克谦 Angela Lew 2003中国图书馆学报2003,29,6:15
5尺度、变化和恢复力:社区旅游规划的视角显示文摘近年来,恢复力规划逐渐作为可持续发展的一种替代范式,为快速变化中的社区发展和社会-生态转型提供了新的视角。社区恢复力这个新兴概念在很多学科已有所涉猎,旅游学者也从某种程度上逐渐接受这一理念。但大多数关于社区恢复力的研究主要关注的是重大灾难和危机等突发事件,鲜有对渐变事件和过程进行研究。因此,建立一个包含缓慢变量的新框架将进一步拓展恢复力相关研究。论文中建立的旅游恢复力模型包含了从慢到快的变化速率以及从业主到社区旅游收益的不同尺度,并得出一个2×2矩阵,该矩阵中呈现了4种相互区别的恢复力主题、方法和测度,涵盖了从企业家维护日常管理的需求到社区灾难的应急、响应和恢复等诸多方面。作者进而通过对台湾乡村旅游的研究,修订了SCR模型,建立了应对扰动和变化的社区尺度、变化和恢复力系统及子系统推广模型。新的模型改变尺度、变化和恢复力的通用模型,具有等级体系,包含一个系统和至少一个子系统,并以阈值线来界定区分变化程度。另外,对SCR模型的四个象限进行了正式的命名,即管理、资源、规划、治理恢复力/可持续性。Alan August Lew 何景明 高彬 2016资源科学2016,38,9:9
6基于旅游与农业联系的游客餐饮感知研究院评价维度与联系机制显示文摘旅游者在目的地的餐饮消费占旅游者总花费的近三分之一,所以加强旅游者餐饮需求与目的地农业生产联系尤为重要,其中游客对旅游目的地餐饮业的感知影响着游客在目的地的餐饮消费行为和回到客源国后的后续餐饮消费行为。本文以在安徽六安天堂寨景区旅游者餐饮感知的结构性访谈为数据来源,用规范的质性研究程序即翻录数据,整理数据;数据分解与初次注解;完整注解数据;数据段分类与联接;理论建构,研究游客对旅游目的地的餐饮感知评价,初步得出旅游者对目的地餐饮感知的7个评价维度即餐饮价格、地方特色、餐饮产品、关联产业、餐饮开发、餐饮产品的原真性、餐饮卫生维度,在每个感知维度下构建二级评价因子并确定相应的权重。文章基于游客餐饮感知信息初步建构出餐饮业与地方农业的联系机制的研究构架图;最后基于游客视角得出了加强旅游地餐饮业与区域经济联系的管理建议。文章对于研究游客餐评价体系,制定加强旅游业与地方农业联系的政策有一定指导意义。韩国圣 李辉 Alan Lew 2015世界地理研究2015,24,2:9
7软件静态结构的依赖网络建模方法与特性分析显示文摘现有的软件复杂网络建模方法,对模型的定义各不相同,缺少统一的框架,导致不同编程语言、不同粒度的软件模型分析对比困难。针对软件的静态结构,分析对比了现有建模方法的特点,提出了软件依赖网络建模方法,将软件系统抽象为计算服务提供者以及它们之间的依赖关系,实现了不同粒度下网络模型的直观映射;通过对Java软件依赖网络的实例分析,证明其具有小世界、高聚类系数的特性,入度基本服从幂率分布,出度基本服从带指数截断的幂率分布,并指出这些网络特性的软件工程含义,探讨了它们对软件开发和维护的指导意义。钱冠群 张莉 张林 Philip Lew 2008计算机科学2008,35,11:8
8区域旅游流空间结构的高铁效应及机理(英文)显示文摘Chinese railway has entered the 'HSR era', while the structure of 'four vertical and four horizontal' railways for transit passengers is almost completed. Taking the Beijing-Shanghai High-Speed Rail(hereinafter referred to as HSR) as an example, this paper first explores HSR's effects on the spatial structure of regional tourist flows using the social network analysis. Next, it notes changes in the accessibility of regional transportation. After analyzing the factors including initial endowment of regional tourism resources, hospitality facilities, the density of the regional tourism transportation network, and locations, the paper discusses the mechanisms through which HSR affects regional tourist flows. The study shows the following:(1) HSR's effects on the spatial structure of regional tourist flows are manifested through the Matthew effect, the filtering effect, the diffusion effect and the overlying effect, and(2) the Matthew effect of HSR is manifested under an obvious interaction of the location, the initial endowment of tourism resources, hospitality capacity, tourist transportation network density and 'time-space compression'. The filtering effect of HSR is manifested for those tourism nodes without favorable location conditions, endowment of tourism resources, hospitality capacity, or tourist transportation network density and without obvious benefits from 'time-space compression'. Those tourism nodes that boast advantages in terms of location condition, endowment of tourism resources, hospitality capacity, tourist transportation network density and obvious 'time-space compression' will become sources for the diffusion effect. HSR will strengthen the aggregation effects of tourist flow in these diffusion sources, which will thereafter diffuse to peripheral tourist areas, manifesting 'aggregation-diffusion'. HSR has overlapped tourists' spatial traveling range over large-scale spaces. However, the overlying effect is only generated in those tourism nodes with a favorable location condition, an endowment of tourism resources, hospitality capacity, tourist transportation network density, and obvious 'time-space compression'.汪德根 王莉 陈田 陆林 牛玉 ALAN August Lew 2016Journal of Geographical Sciences2016,26,12:7

11Genetic associations with adverse events from anti-tumor necrosis factor therapy in inflammatory bowel disease patients显示文摘AIM To study the type and frequency of adverse events associated with anti-tumor necrosis factor(TNF)therapy and evaluate for any serologic and genetic associations.METHODS This study was a retrospective review of patients attending the inflammatory bowel disease(IBD) centers at Cedars-Sinai IBD Center from 2005-2016. Adverse events were identified via chart review. IBD serologies were measured by ELISA. DNA samples were genotyped at Cedars-Sinai using Illumina Infinium Immunochipv1 array per manufacturer's protocol. SNPs underwent methodological review and were evaluated using several SNP statistic parameters to ensure optimal allele-calling. Standard and rigorous QC criteria were applied to the genetic data, which was generated using immunochip. Genetic association was assessed by logistic regression after correcting for population structure.RESULTS Altogether we identified 1258 IBD subjects exposed to anti-TNF agents in whom Immunochip data were available. 269/1258 patients(21%) were found to have adverse events to an anti-TNF-α agent that required the therapy to be discontinued. 25% of women compared to 17% of men experienced an adverse event. All adverse events resolved after discontinuing the antiTNF agent. In total: n = 66(5%) infusion reactions; n = 49(4%) allergic/serum sickness reactions; n = 19(1.5%) lupus-like reactions, n = 52(4%) rash, n = 18(1.4%) infections. In Crohn's disease, Ig A ASCA(P = 0.04) and Ig G-ASCA(P = 0.02) levels were also lower in patients with any adverse events, and anti-I2 level in ulcerative colitis was significantly associated with infusion reactions(P = 0.008). The logistic regression/human annotation and network analyses performed on the Immunochip data implicated the following five signaling pathways: JAK-STAT(Janus Kinase-signal transducer and activator of transcription), measles, IBD, cytokine-cytokine receptor interaction, and toxoplasmosis for any adverse event. CONCLUSION Our study shows 1 in 5 IBD patients experience an adverse event to anti-TNF therapy with novel serologic, genetic, and pathways associations.Daniel Lew Soon Man Yoon Xiaofei Yan Lori Robbins Talin Haritunians Zhenqiu Liu Dalin Li Dermot PB McGovern 2017World Journal of Gastroenterology2017,23,40:4
