城市文化软实力构建的“网都”范式

当前全球数字网络化的发展浪潮和历史背景下,"网都"型文化中心城市建设成为转变城市文化发展方式、提升城市文化软实力的新的战略路径和城市设计愿景。城市发展的"网都"形态具有多元文化范式,要根据不同城市的特点和文化基础,推进网络媒介城市(media city)、网络文化产业高地、网络文化名城、互联网总部基地、文化科技融合的创新引领中心、网络文化宜居之都、互联网枢纽城市等不同类型的"网都"建设。不同的网都范型(paradigm)关切到城市文化软实力的不同层面,存在着从硬文化实力向软文化实力的渐变和过渡谱系;既可以单独构建特色网络文化城市的核心性格与差异化竞争力,也可以综合构建城市文化软实力的体系化架构。     

Limit Theorems for Semi-Markov Queues and Their Applications

We begin by definition of semi-Markov flow and discussion of its properties. Asymptotic behavior of multi-server and single-server queueing systems is studied under assumption of time-compression or service time growth. The results obtained are used for calculation of large systems reliability. Statistical estimates of parameters involved are also provided.     

Labor Market Disparities Between African Americans and Afro Caribbeans: Reexamining the Role of Immigrant Selectivity

Black immigrants from the Caribbean have long attained greater labor market success than African Americans. The most recent studies show that Afro Caribbeans have earnings that are approximately 16% greater than African Americans and that Afro Caribbeans are as much as 21% more likely to be employed than African Americans. The most prominent explanation for greater Afro Caribbean success is that, because they have chosen to migrate, Afro Caribbeans are positively self‐selected on characteristics that are key for success in the U.S. labor market. Proponents of immigrant selectivity argue that migrants have greater levels of both hard and soft skills than nonmigrants. Using data from the National Survey of American Life—the first social survey to provide a nationally representative sample of both African Americans and Afro Caribbeans—this study finds that Afro Caribbeans have greater hard skills than African Americans but split the difference on two measures of soft skills: African Americans and Afro Caribbeans are matched on John Henryism, but African Americans have greater personal mastery than Afro Caribbeans. Contrary to expectations, controlling for differences in hard and soft skills does not provide for a meaningful reduction in labor market disparities between African Americans and Afro Caribbeans.     

论特色文化城市理论体系建构研究与实践创新——中国本土化特色文化核心价值的理论体系与范式建构

本文从世界新文化产业分工理论和"城市文化资本"理论的双重视角出发,首次提出了本土化特色文化城市理论的结构框架、研究与建构入径、新的理论内核,特别是在总结、研究、比较国内外特色文化城市发展的历史经验和理论研究成果的前提下,提出了中国本土化的特色文化城市的核心价值论、"双核理论"和特色文化城市的理论研究与建构操作的整体范式。     

人才流动的增智效应对我国酒店业人才开发的启示

人才是酒店资源中最重要的资源,酒店的人才管理兼具投资性大和流动性强的特点,如何进行有效的人才投资、又防止人才过度流失是酒店人力资源开发和管理中的一个重要课题。按照人才流动的增智效应理论,人才的合理流动将带来酒店业的发展;即使显而易见的酒店业之间的人才流失,也会带来酒店人才开发管理中深层次的增智效应,必将有利于提升酒店管理水平和服务质量,并给出积极的应对策略。     

低压及欠平衡钻井中注气量对井内压力的影响

以多相瞬变流理论为基础,建立了井筒内气液两相流动模型,并对低压欠平衡钻井中注气量对井内压力的影响关系和规律进行计算和分析。计算分析结果表明,注气量对井内压力的影响除与注气量本身大小有关外,还与井深、井眼与钻柱结构尺寸、井内液相流量和性质等因素密切相关。单纯增大注气量并不一定就必然会导致井内压力的降低,这取决于所给条件下构成井筒内气液两相流体的静液压力和流阻间的平衡关系。介绍的模型及方法对确定低压欠平衡钻井过程中各相关参数、地面压缩机组的配置、以及设计方案等有一定指导意义。     

1981—2014年中国资本服务流量测算——基于截断正态退役分布和几何役龄效率剖面

通过梳理资本核算理论框架,结合中国实际情况测量了1981-2014年资本服务流量。资本分类、组合役龄效率-退役剖面计算、资本回报率确定和初始单位效率生产性资本存量估计等方面与既有研究有所不同。测量结果表明:按照1990年不变价格,各类资本服务流量呈增加趋势,其中无形资产服务流量前期较为波动;设备类服务流量增速最高;总资本服务增长率前期呈V型后期呈倒U型,与GDP增速变动不一致,整体来看前者高于后者;比较发现测量结果高于其它研究,差距先收敛后扩大。     

Backward capacity-filtering for electronics Fabs

In electronics Fabs such as semiconductor Fabs and liquid crystal display (LCD) Fabs, which are capital-intensive, finite-capacity planning is critical to achieving full-capacity production and on-time production. However, existing finite-capacity planning methods do not adequately reflect the actual capacity profiles of an electronics Fab. In this paper, we propose a new Fab-level capacity-filtering procedure to generate finite-capacity plan: a backward capacity-filtering procedure for generating finite-capacity release plan. When developing the Fab-level filtering procedures, we use stage-level capacity-filtering algorithms as a key building block. In this study, we enhance the previous capacity-filtering algorithms proposed by one of the authors in order to facilitate the practical requirements of electronics Fabs. We apply the proposed capacity-filtering method to a modern LCD–TFT Fab in Korea. Performance analyses demonstrate that the proposed method is superior to existing methods.     

智库建设的困境摆脱与国家软实力提升

智库是国家软实力的重要体现。改革开放以来，国家软实力的提升为智库建设的机制创新创造了有利条件。但在新时期新的历史条件下，由于体制内官方智库的非自主性、体制外智库发展的滞后性、智库设置和定位的模糊化、智库建设和发展的保障不足等仍影响着国家软实力的提升。不断加强官方智库建设，高度重视半官方智库建设，加大民间智库的扶持力度，引导大学附属型智库的积极发展，建立各类智库的互动合作机制，是我国进一步提升国家软实力的必由之路。     

Security branding and digital narrations. Security issues representation on Twitter

In the contemporary multicentric world, sovereign states have to manage carefully the construction of their image, defining their role and aspirations. With the re-definition of the state centric politics, stories become relevant: communication is a form of power, and networked forms of communication are becoming progressively a way to conquer the transnational public spheres. Through strategic narratives of foreign politics, states try to set up the ‘tales’ of international affairs and foreign strategies, to suggest a world vision, a causal interpretation, determining frames that affect transnational actors’ position in the international environment. Sovereign states develop these kind of frame using tools and theories referred to the commercial branding tradition to promote and support their own policies and identity. We decided to investigate how that process is made through information diffusion on digital platforms.

In this work, it has been analyzed the content presented through Twitter posts by the Foreign Ministries accounts of four different States dissimilar for geopolitical positioning and security concerns (USA; Israel; France; Sweden), for a period of three months (9/1/2015-11/30/2015); leading to the identification of different models and characteristic patterns of self-representation.

The thematic content analysis, based on the identification of macrocategories and micro-issues, has led to the identification of different models and characteristic patterns of self-representation, determined by domestic vicissitudes, and has shown some regularities, caused by the branding vocation of autobiographical online contents.
