“十二五”中国地毯进出口市场分析

长期以来,中国地毯产业以出口为主。本文主要分析了"十二五"期间中国地毯产业的进出口情况。分析了中国地毯产业的进出口规模和价格,主要的进出口产品品种及国家,并对我国地毯产业的未来发展进行了展望。预计未来3年,中国地毯出口将进一步增加,进口维持目前水平,甚至减少,而平均出口价格将会进一步被拉低。     

Efficient algorithms for multiple destinations routeing

A number of important problems in computers and telecommunications, such as distributed databases and multipoint multimedia conferencing, all require the solution of a generic problem called multiple destinations routeing (MDR). In this paper, we formulate the MDR problem as a zero-one integer programming problem and propose a technique to reduce the computation required for the optimum solution. Three heuristics are designed for large MDR problems. Heuristic A can offer different degrees of optimality with different amounts of time allowed for the solution. Heuristic B is a modification of Prim's algorithm for the minimum spanning tree. It gives a fairly good solution with very little computation. Heuristic C is based on Heuristic B and is for minimizing the number of edges in the multicast tree (i.e. assuming that all edge weights are the same). It always gives a better solution than Heuristic B. Simulation on two example networks shows that Heuristics A and C always give better solutions (or lower cost connection paths) than the improved RS algorithm, which has up to now been the best heuristic.

公示语的功能特点与汉英翻译研究

公示语是国际化都市、国际旅游目的地语言环境、人文环境的重要组成。公示语所展示的信息状态既有“静态”，也有“动态”；具有指示性、提示性、限制性、强制性四种突出的应用示意功能。对公示语的任何歧意、误解、滥用都会导致不良的社会影响。只有认真探讨英语公示语的功能意义和语言丈化内涵，才能准确而充分地发挥英语公示语在我国深化改革、扩大开放、区域国际化进程中的信息服务作用。     

The assessed value of cultural destinations in Toronto

Theory suggests many benefits to a city from cultural destinations (CDs). This study offers a framework for evaluating CDs through studying visitors to CDs and visitors to other, less cultural destinations, which we call retail destinations (RDs). As each destination represents differing positions along our “cultural continuum,” we examine how visitors perceive the destinations and report their behaviors in each. We selected three CDs and three RDs in Toronto, surveying 30 adults in each destination about their behavior and impressions. Our findings show significant differences between the respondents in the CDs and the RDs. Some findings resonate with existing theory, in that CD respondents were more likely to be highly educated and White, non-Hispanic. However, other findings suggest avenues for examination, in that CD respondents did not report greater wealth or spending than did the RDs but did mention socializing as the primary reason for visiting a CD more so than those visiting an RD. These findings suggest that by encouraging CDs, cities may improve the quality of life for residents and visitors. Thus, cities might do well to use their municipal policy and economic development tools to drive revenues to cultural destinations or to foster CD uses in retail destinations.

IP是品牌进化的高级阶段,是品牌打造的一种新工具。在乐山市加快建设世界重要旅游目的地的背景下,商业化运营"乐山味道"IP有利于丰富旅游业态,更新IP自身产业体系,实现IP自身价值,提升旅游目的地竞争力。文章在对乐山市发展美食旅游IP的优势与乐山市美食旅游品牌化发展现状分析的基础上,认为"乐山味道"IP商业化运营前提为建设完善饮食文化数据库,通过美食IP聚焦、IP塑造、IP运营和IP扩张,实现提量增值的生态式规模化产业链聚集,满足游客对乐山味道及所蕴含的人文内涵的体验与期待。     

A “Group-Division Multiple Access” framework for channel access to multiple destinations

We consider the problem of media-access control in multiple-cell networks, such as ad hoc networks in which clusterheads take on a role similar to base stations. We assume that a single channel is used by all cells, and that the user populations that transmit to different base stations overlap, causing interference in the neighboring cells. Starting with a two-destination network, we introduce the “Group-Division Multiple Access” (GDMA) concept, according to which different groups of users multiplex their transmission in time while being free to use the protocol of their choice within their own group. We show that use of GDMA provides higher stable throughput than a “free-running” scheme (under which all slots are available to all users) when the First-Come First-Serve collision–resolution algorithm is used as the channel-access protocol, and we show how performance depends on the degree of overlap of communication and interference regions. Finally, we show that this approach can be applied to larger cellular-like networks as well.

旅游地社会—生态系统子系统脆弱性比较分析——以大别山区9县(市)为例

基于社会-经济-环境模型和压力-状态-响应模型,采用综合指数法对大别山区典型县域2009—2016年社会、经济和生态子系统脆弱性进行测度和比较分析. 研究发现:(1)经济子系统脆弱性呈快速下降趋势,社会、生态子系统脆弱性有所抬升; 压力指数对系统脆弱性贡献度逐步上升,响应指数贡献度逐步下降,状态指数贡献度相对稳定.(2)3个子系统的压力指数、状态指数、响应指数和脆弱性指数在变化幅度、变化趋势、强弱程度和阶段划分4个方面差异明显.(3)游客密度、城镇化率等社会、经济子系统压力因素成为系统脆弱性降低的主要阻碍因素.
