鄂西恩施州旅游经济发展策略研究

湖北省恩施土家族苗族自治州蕴藏着巨大的旅游资源,依托州政府2006年“旅游兴州”策略和2009年湖北省“两圈一带”的发展战略,恩施州旅游经济获得了迅速发展.但是在旅游资源开发和旅游经济发展过程中,也存在着一些问题,需要加以解决.本文针对恩施州旅游基础设施、旅游产品开发、旅游市场营销、旅游人才培养等方面进行研究,并提出了相关建议.     

美国冷战战略发展与演变——从杜鲁门到布什

二战之后,美、苏一跃而成为世界上的两个超级大国。由于意识形态的差异,加上战后苏联势力范围的不断扩张,这被美国认为是对其领导下的西方自由世界的严重威胁。自总统杜鲁门提出意图遏制苏联的"杜鲁门主义"之后,二者由战时的合作转为战后的竞争与对抗。一直到冷战结束前的时期内,美国历任总统在上台之后都不约而同地提出貌似具有与其前任不同的内容然而实质却基本不变的冷战战略。美国冷战战略的发展与演变贯穿整个冷战过程的始终,深刻影响着其自身乃至整个世界政治格局的变迁。     

新型城镇化战略下生活体育设施建设的思考——基于CiteSpace可视化分析

新型城镇化包含了以人为本以及通过不断改善民生提高城镇居民生活满意度两方面的战略思想。生 活体育作为新型城镇化中精神文明建设的一个方面,不仅是促进新型城镇化发展的重要手段,也体现着新 型城镇化发展的重要价值。通过发展生活体育,新型城镇化将以提高居民生活质量为目标,提高居民身体 素质的同时提高居民生活满意度。通过CiteSpace可视化分析发现,国内对生活体育研究还处于主题分散 ,框架不明晰的阶段。将在新型城镇化战略指导下,通过搭建生活体育设施建设框架,不仅可以弥补体育 手段和生活体育理论联系的不足,而且可以弥补生活体育设施建设研究领域中缺乏的相关文献回顾,同时 为未来生活体育设施建设提供了理论指导模型。     

中国体育用品业竞争力及提升战略分析

从竞争力结果和竞争力过程两个方面构建了中国体育用品业竞争力的动态模型,并分别从产业基础因素、核心因素和环境因素三个方面对中国体育用品业竞争力过程进行了评价,从竞争优势和产业利润方面对竞争力结果进行了评价,最后,从"促进产业集聚和升级、优化产业生态结构"等七个方面提出了加快体育用品产业可持续发展的战略选择。     

基于突发词对主题模型改进算法的微博热点话题发现研究

[研究目的]针对主流话题发现模型存在数据稀疏、维度高等问题,提出了一种基于突发词对主题模型(BBTM)改进的微博热点话题发现方法(BiLSTM-HBBTM),以期在微博热点话题挖掘中获得更好的效果。[研究方法]首先,通过引入微博传播值、词项H指数和词对突发概率,从文档层面和词语层面进行特征选择,解决数据稀疏和高维度的问题。其次,通过双向长短期记忆(BiLSTM)训练词语之间的关系,结合词语的逆文档频率作为词对的先验知识,考虑了词之间的关系,解决忽略词之间关系的问题。再次,利用基于密度的方法自适应选择BBTM的最优话题数目,解决了传统的主题模型需要人工指定话题数目的问题。最后,利用真实微博数据集在热点话题发现准确度、话题质量、一致性三个方面进行验证。[研究结论]实验表明,BiLSTM-HBBTM在多种评价指标上都优于对比模型,实验结果验证了所提模型的有效性及可行性。     

On Beyond E-journals: Integrating E-books,Streaming Video,and Digital Collections at the HELIN Library Consortium

With trends in collection development moving toward digital, streaming resources, and acquiring sets of materials, the Higher Education Library Information Network (HELIN) Consortium pulled together cataloging, acquisitions, and licensing information through a discovery platform. The discovery layer, in this case Innovative Interface's Encore, harvests disparate collections and enables the library user to easily refine her search through facets. Rice Sanders described the HELIN Consortium's Encore implementation and experiences, while McQuillan highlighted the West Bloomfield Township Public Library use of the Encore platform and other products.     

Topics in dynamic research communities: An exploratory study for the field of information retrieval

Research topics and research communities are not disconnected from each other: communities and topics are interwoven and co-evolving. Yet, scientometric evaluations of topics and communities have been conducted independently and synchronically, with researchers often relying on homogeneous unit of analysis, such as authors, journals, institutions, or topics. Therefore, new methods are warranted that examine the dynamic relationship between topics and communities. This paper examines how research topics are mixed and matched in evolving research communities by using a hybrid approach which integrates both topic identification and community detection techniques. Using a data set on information retrieval (IR) publications, two layers of enriched information are constructed and contrasted: one is the communities detected through the topology of coauthorship network and the other is the topics of the communities detected through the topic model. We find evidence to support the assumption that IR communities and topics are interwoven and co-evolving, and topics can be used to understand the dynamics of community structures. We recommend the use of the hybrid approach to study the dynamic interactions of topics and communities.     

I.D.ology and the technologies of public (school) space: an ethnographic inquiry into the neo-liberal tactics of social (re)production

This paper presents findings from a qualitative UK study exploring the social practices of schoolchildren visiting an interactive science discovery centre. It is promoted as a place for ‘learning through doing’, but the multi-modal, ethnographic methods adopted suggest that children were primarily engaged in (1) sensory pleasure-taking and (2) playing out shifting relations of affect and sociality. In discussing this, the paper does not ask what children are learning, but rather what they are doing – and how this does or does not relate to the scientific principles presented to them. The paper confirms studies suggesting that discovery centres are highly social spaces in which cognitive processing is only one aspect but goes further in suggesting that the twin dimensions of the social and the sensory are so paramount in governing children's responses to exhibits as to eclipse thoughts of science. The findings suggest that old-style live demonstrations are more effective than technologically interactive exhibits in foregrounding scientific concepts.     

Party Identifiers

As Digital Media develops into a mature market, the proper referencing of digital content is increasingly critical. The Identification of Parties who contributes to content is key to ensure efficient discovery services and royalty tracking. Far from being simple numbers, Party Identifiers such as International Standard Name Identifiers (ISNI) are built on rigorous structures meeting the requirements of diverse media such as books, music or films. Designed to accurately identify Natural Persons and Legal Entities alike, Party Identifiers must also support language variances, cultural diversity and stringent data privacy regulations.     

Navigating the MLA Bibliography—Redux: Performance Across Vendor Platforms and Discovery Tools

ABSTRACT

The authors updated their 2009 article on the MLA International Bibliography (MLAIB) by comparing it across three vendor platforms to determine if seemingly comparable searches continued to produce varying results. As much as possible, the authors tested the same searches as were tested in the original article and added additional ones for further exploration. Findings illustrate that while there are fewer differences than was the case previously, differences still exist. The authors also investigated discovery services to identify factors affecting MLAIB searches. The authors discuss the impact of their findings on users, from undergraduates to faculty researchers.
