信息获取权客体辨析     

周淑云  王好运 《图书馆》2015,(1):18-20,27

信息获取权客体是指信息获取权所指向的对象,狭义的信息获取权的客体即信息资源。作为权利客体的信息资源类型多样、特征各异,从信息获取的角度而言,信息资源依据不同的分类标准可分为多种类型。信息资源具有公共性、可再生性、时效性、价值性、稀缺性等特征。信息资源这些特性的存在是信息获取权设立的前提。只有信息获取权得到保障,社会公众信息需求才能得到满足,信息资源的价值方能最大限度地实现。  相似文献

薛鹏 《湖北函授大学学报》2015,(11):24-25

伴随着我国高等教育收费制度的实行,有很大一部分家庭经济困难的学生出现了上学难的问题。为了解决这一难题,从1999年起国家推行了助学贷款制度政策,经过多年的发展,助学贷款对帮助困难学生起到了很大的作用,但是随着时代的发展也难免会出现一些新的问题。本文从当前贷款制度实施过程中出现的问题展开分析,结合实际为完善助学贷款制度提出建议。  相似文献   

内支线船舶岸电系统改造策略及经济影响因素研究     

宋向群  周勇  王文渊  唐国磊 《上海海事大学学报》2015,36(4):43-47

绿色港口建设背景下,为促进港口节能减排,航运公司面临是否对其经营的船舶进行岸电改造的问题.选取内支线船舶为研究对象,以寿命期内船舶在泊期间用电成本净现值最小为目标,构建考虑排放约束的船舶岸电改造策略动态优化模型.采用逐年比较法求解该模型得到最优策略,并研究环境税、岸电价格对改造决策的影响.算例结果表明:船舶剩余寿命大于14 a时,进行岸电改造是经济可行的,且越早实施改造越经济;船舶在泊期间的排放成本约占总用电成本的0.8%~4.0%;环境税征收标准对岸电改造决策影响较小;从经济角度看,低于1.14元/(k W·h)的岸电收费标准宜于船舶岸电系统改造的推广.研究方法及结果可为航运公司运营船舶提供决策参考.  相似文献   

我国兽药产业发展现状分析与建议     

李逸波  周瑾  张亮 《保定学院学报》2015,(2):16-21

我国兽药产业呈现企业总量规模较庞大,结构差异性与区域性明显,不同类别企业产值、产能利用水平差异大,出厂产品的抽检合格率水平较高且较为稳定等特点。但就产业整体来看,我国兽药产业生产环节存在产业集中水平低,规模不经济;低水平重复建设,利润低;产业结构不合理;产业组织内部管理不规范等问题。因此,亟待政府合理规划布局,加速结构调整;政府与企业联合配置资源,保障产业运行效率;企业内部也需以人为本,重视人才与管理,提升企业自身实力。  相似文献   

Flip channel: A microfluidic device for uniform-sized embryoid body formation and differentiation     

Ying-Hua Chen  Chien-Chung Peng  Yi-Chung Tung 《Biomicrofluidics》2015,9(5)

This paper reports a two-layered polydimethylsiloxane microfluidic device—Flip channel, capable of forming uniform-sized embryoid bodies (EBs) and performing stem cell differentiation within the same device after flipping the microfluidic channel. The size of EBs can be well controlled by designing the device geometries, and EBs with multiple sizes can be formed within a single device to study EB size-dependent stem cell differentiation. During operation of the device, cells are positioned in the designed positions. As a result, observation and monitoring specific population of cells can be achieved for further analysis. In addition, after flipping the microfluidic channel, stem cell differentiation from the EBs can be performed on an unconfined flat surface that is desired for various differentiation processes. In the experiments, murine embryonic stem cells (ES-D3) are cultured and formed EBs inside the developed device. The size of EBs is well controlled inside the device, and the neural differentiation is performed on the formed EBs after flipping the channel. The EB size-dependent stem cell differentiation is studied using the device to demonstrate its functions. The device provides a useful tool to study stem cell differentiation without complicated device fabrication and tedious cell handling under better-controlled microenvironments.  相似文献   

The Sporting Lives of Sir Shenton Thomas and the Male European Internees at Changi Prison Camp During the Japanese Occupation of Singapore, 1942–1945     

Peng Han Lim  Mohd Salleh Aman 《国际体育史杂志》2015,32(3):466-483

During the Japanese occupation of British Malaya and Southeast Asia from the years 1942 to 1945 there were reports of POWs being allowed to play cricket, football, rugby and basketball, as told by Kevin Blackburn in The Sportsmen of Changi published in 2012. This research about the sporting lives of a Governor and male European internees at Singapore's Changi prison is likely to be first detailed research on this topic. The authors depended mainly on four published diaries and 262 issues of the men's camp newspaper, Changi Guardian, to account for the male internees' casual and competitive cricket, football, hockey, volleyball, badminton, tennis and boxing matches that were played during internment. The Japanese Military Administration allowed the male internees to organize their daily lives and play games that they indulged in during the pre-War period as the British dominated the Singapore Cricket Club, Penang Cricket Club and Perak Club. The internees were able to play the various games and matches in spite of the limited food and sparse facilities. Many of the cricket and football games that were played were organized as inter-state, inter-club or league matches. These games were played with improvized equipment and rules.  相似文献   

税收政策在美国职业体育场馆建设中的作用及其启示     

王龙飞  王朋 《西安体育学院学报》2015,(1):33-39

运用文献法对税收政策在美国职业体育场馆建设中的作用进行了分析。研究认为税收政策在美国职业体育场馆建设中起到了确保公共财政的充分供给、保障公共财政投入的有效回收、维护纳税主体的公平权益等作用。在此基础上结合我国国情,运用对比分析法,对我国大型综合性体育场馆的税收政策提出启示,认为我国应给予大型综合性体育场馆税收政策支持、运用税收政策拓展大型综合性体育场馆建设资金的融资渠道、通过税收杠杆对大型综合性体育场馆的财政投入进行回收、运用税收政策保障大型综合性体育场馆建设中的税赋公平。  相似文献
