第43届世乒赛女子单打比赛评析

第43届世界乒乓球锦标赛,中国选手邓亚萍、乔红等在面临欧亚外国选手及“海外兵团”有力挑战后,连闯数关,包揽世乒赛女子单打前三名,说明中国女队的技战术水平在世界乒坛仍占有较大优势,心理素质也日趋成熟,但中国女队也存在后备力量不理想,年轻选手心理素质不够稳定,技术风格不够凶狠等问题,需引起我们思想上足够的重视。     

词汇语义探讨

语义问题是词汇研究的重心。本从词定义的模糊性、词的语义单位及单个词内的语义之间的关系及组织等三方面着手对词汇语义问题进行了探讨。

SIP协议及其在网络中的应用

随着下一代互联网技术的不断发展,人们将不仅仅满足于将现有的PSTN(公共电话网)业务移植到IP网,而是需要电信运营商提供一个优秀的体系架构,将话音业务、视频业务、新兴的互联网业务整合到一个统一的框架中.SIP协议就是其中的关键纽带.

中国足球超级联赛U23新政何以有效?——基于“足协-俱乐部”的博弈

中超联赛自2017赛季推出U23新政以来备受争议。在"上有政策下有对策"的非合作博弈下,U23新政如何才能实现政策初衷?该文首次采用不完全信息静态博弈模型分析了U23新政下足协与俱乐部的博弈均衡。研究表明：（1）足协推行新政的最优概率为俱乐部采取积极策略给足协带来的净收益与消极策略带来的净收益之比,实质上取决于俱乐部的遵从度。（2）在缺乏讨价还价权时,俱乐部对新政采取消极应对策略是为了减少净损失。俱乐部积极应对的最优概率为消极应对的净损失占其与积极应对的加成即期收益损失之和的比值,实为两害相权取其轻。为激励俱乐部采取积极策略,应降低俱乐部消极应对策略的净收益或积极应对策略的加成即期收益。（3）提高U23新政有效性的治标之策是减少U23政策对中下游球队的冲击,实行有差别的U23政策;对U23球员上场时间低于均值的俱乐部,实行等额或超额递减分成机制。治本之策是培育一个可预期、可持续、可盈利的足球市场,俱乐部能够内生出建立百年基业的长效机制;继续深化足协的去行政化改革,使之向完全社团法人转型。

第四十三届世乒赛中国及欧洲优秀男双选手技术分析

运用乒乓球比赛中分段指标评估法，对第四十三届世乒赛中国及欧洲优秀男双选手的技战术运用情况进行分析，认为发抢段和接发抢段技术仍是男双取胜的主要因素：１）通过发球、发抢、接发抢得分；２）通过前三板为相持的主动创造更多机会；在发抢段、接发抢段和相持段中合理地运用了“变化”。     

(International) R&D collaboration and SMEs: The effectiveness of targeted public R&D support schemes

This study analyses the impact and effectiveness of targeted public support for R&D investment at the firm level. We test whether the policy design aiming at incentivizing (international) collaboration and R&D in SMEs achieves input as well as output additionality. Our results show that the targeted public subsidies trigger R&D spending, especially so in internationally collaborating SMEs. We further evaluate the different impact of privately financed and publicly induced R&D investment on innovation performance. The results confirm that the publicly induced R&D is productive as it translates into marketable product innovations. While both types of R&D investments trigger significant output effects, the effect of policy-induced R&D investment on sales from market novelties is highest for international collaborators as well as for SMEs.     

Multinational subsidiary knowledge protection—Do mandates and clusters matter?

International knowledge spillovers, especially through multinational companies (MNCs), have recently been a major topic of academic and management debate. However, most studies treat MNC subsidiaries as relatively passive actors. We challenge this assumption by investigating the drivers of knowledge protection intensity of MNC subsidiaries. We argue that knowledge protection intensity is determined by MNC subsidiary mandates and by opportunities and risks originating from the host region. We hypothesize that not just competence-creating but also competence-exploiting mandates increase knowledge protection intensity. In addition, technological cluster regions in the host country can be expected to provide opportunities for knowledge sourcing and MNC subsidiaries may be willing to protect knowledge less intensively to participate in cluster networks. We test our hypotheses using a dataset of 694 observations of 631 MNC subsidiaries in Germany and develop recommendations for research, managers and policy makers.
