中华文字——文明古国源远流长的语言符号

文字是记录语言的符号,中国是世界上最早创造和使用文字的国家。我国的象形文字比较及致少要早二千余年。殷墟甲骨文并不是最早的文字,我国文字已有八千年以上的历史。从距今七八千年的甘肃大地湾刻划符号到距今六千年前的西安半坡刻划符号,再到五六千年前的良渚文化、龙山文化等等象形文字符号……,中国文字源远流长,是世界上唯一从古至今仍在流行、通用并充满生机和活力的古老文字。中国文字是中华各民族的先民共同创造的,不应称作“汉字”。     

解读《中华人民共和国物权法》关于业主的建筑物区分所有权的规定

《物权法》第六章专章规定了建筑物区分所有权制度,使关乎千家万户的房屋产权有了真正的法律界定和保护依据。为使《物权法》的建筑物区分所有权制度能真正得到实施,业主们需要认清自己权利和义务,树立所有权意识,并通过公民的参与来推动国家配套法规与实施细则的出台。秉承上述两点,文章解读和阐释了《物权法》中建筑物区分所有权的内容、建筑物区分所有权客体的权利归属及建筑物区分所有权业主之间的关系。     

Institutional complementarities: The origins of experimentation in China’s plug-in electric vehicle industry

A vast literature on technology transitions within industries suggests that early phases of new technologies are marked by periods of intense experimentation, but we know little about the conditions under which these periods emerge. We apply inductive, grounded theory-building techniques to examine what prompts firms to experiment across one emerging technology platform—plug-in electric vehicles (PEVs)—in China. Triangulating annual vehicle make and model sales data from 2003 to 2016 (plus monthly data from 2010 to 2016); 112 English and Mandarin archival documents from industry, academic, and news outlets; and 51 semi-structured interviews with industry, government, and academic stakeholders, we develop four in-depth case studies. We find that in contrast to the innovation trajectories of multinational and Chinese arms of joint venture (JV) firms, independent domestic Chinese firms (those with no history of international JV partnerships) are undertaking significant experimentation across multiple levels—infrastructure, core system, subsystem, and component—of the emerging PEV technology platform. We propose the concept of “institutional complementarities” to describe how interactions among institutions—here the national JV regulation and local market support and subsidies—may have turned regional markets into protected laboratories, extending the incubation periods for independent domestic firm experimentation. While this diverse experimentation may be an important antecedent of technology transition, consolidation induced by national policy standardization or competitive pressure may be required for PEV innovations to scale beyond their early, protected regional markets.

On the p-norm joint spectral radius

The p-norm joint spectral radius is defined by a bounded collection of square matrices with complex entries and of the same size. In the present paper the author investigates the p-norm joint spectral radius for integers. The method introduced in this paper yields some basic formulas for these spectral radii. The approach used in this paper provides a simple proof of Berger-Wang's relation concerning the ∞-norm joint spectral radius.

校体联合--体制转型时期高校办高水平运动队的对策

文章针对我国高校试办高水平运动队这一现象，认为在当前体制转型时期，我国大部分普通高校尚未完全具备办高水平运动队的条件，与体工队联合办队是高校办高水平运动队的较好模式，并对这种办法提出了相应建议。     

篮球运动员踝关节柔韧性、本体感觉与踝关节损伤的预期性研究

在篮球运动员群体中，踝关节损伤非常普遍，引起踝关节损伤的内在诱发因素很多。本研究对大学篮球运动员踝关节损伤预期性研究，发现踝关节本体感觉(主要是内翻本体感觉)可以作为同侧肢体踝关节损伤的预测指标，而踝关节柔韧性不能作为踝关节损伤的预测指标；本研究中男女篮球运动员踝关节损伤无显性性别差弄。
