双元创新视角下新能源汽车企业创新效率提升路径研究--基于模糊集定性比较分析(fsQCA)

运用DEA模型对我国新能源汽车企业2015—2019年的创新效率进行测算,并基于双元创新视角,选择探索性创新投入、开发性创新投入、政府补贴、企业性质、企业规模和融资约束作为前因解释变量,通过fsQCA方法对提高新能源汽车企业创新效率的有效路径进行识别,总结归纳为“渐进式创新主导型”、“开拓式创新主导型”、“双元创新驱动型”和“政府补贴支持型”四种构型。     

理智与情感:为历史“正名”的方法——从刘保昌长篇小说《楚武王》谈起

历史书写中的“最炫流行风”在今天的文化市场上大行其道——用拆解、谐谑、碎片化、戏拟等方式拉平历史的深度,以“傲慢与偏见”来充抵叙述历史的自信,也经由这种时尚化的叙述使历史以“轻松一刻”的形式实现消费欲望的满足.刘保昌的《楚武王》则疏离“流行前线”,以史料为据,正本清源,守正而出新,为历史“正名”,以彰显历史意识、历史理性的写作姿态,以坚持文学之理想力量的叙事激情,以有文化承担的叙事态度显示出对当代历史小说叙事品格与尊严的坚守.     

城市青年的社会冲突意识研究

了解城市青年对社会群体间冲突的感知,并找到产生这种冲突意识的根源,对改革开放的顺利进行有重要意义。公平感是影响城市青年社会冲突意识的重要因素,以往学者未关注的信任因素也对冲突意识有显著影响,特别是"政治信任"和"一般人际信任"因子,所以,对政府权威机构的信任和社会一般他人的信任都可以有效降低城市青年社会冲突意识。     

China’s Choice of Analytical Models for Its Anti-Monopoly Law

Modern analytical models for anti-monopoly laws are a core element of the application of those laws. Since the Anti-Monopoly Law of the People’s Republic of China was promulgated in 2008, law enforcement and judicial authorities have applied different analytical models, leading to divergent legal and regulatory outcomes as similar cases receive different verdicts. To select a suitable analytical model for China’s Anti-Monopoly Law, we need to consider the possible contribution of both economic analysis and legal formalism and to learn from the mature systems and experience of foreign countries. It is also necessary to take into account such binding constraints as the current composition of China’s anti-monopoly legal system, the ability of implementing agencies and the supply of economic analysis, in order to ensure complementarity between the analytical model chosen and the complexity of economic analysis and between the professionalism of implementing agencies and the cost of compliance for participants in economic activities. In terms of institutional design, the models should provide a considered explanation of the legislative aims of the law’s provisions. It is necessary, therefore, to establish a processing model of behavioral classification that is based on China’s national conditions, applies analytical models using normative comprehensive analysis, makes use of the distribution rule of burden of proof, improves supporting systems related to analytical models and enhances the ability of public authorities to implement the law.     

Spatial variation in soil inorganic nitrogen across an arid urban ecosystem

We explored variations in inorganic soil nitrogen (N) concentrations across metropolitan Phoenix, Arizona, and the surrounding desert using a probability-based synoptic survey. Data were examined using spatial statistics on the entire region, as well as for the desert and urban sites separately. Concentrations of both NO₃-N and NH₄-N were markedly higher and more heterogeneous amongst urban compared to desert soils. Regional variation in soil NO₃-N concentration was best explained by latitude, land use history, population density, along with percent cover of impervious surfaces and lawn, whereas soil NH₄-N concentrations were related to only latitude and population density. Within the urban area, patterns in both soil NO₃-N and NH₄-N were best predicted by elevation, population density and type of irrigation in the surrounding neighborhood. Spatial autocorrelation of soil NO₃-N concentrations explained 49% of variation among desert sites but was absent between urban sites. We suggest that inorganic soil N concentrations are controlled by a number of ‘local’ or ‘neighborhood’ human-related drivers in the city, rather than factors related to an urban-rural gradient.

科学家的精神动力与爱国主义

一、科学家献身国防的精神动力爱因斯坦曾在普朗克六十寿诞的庆祝会上指出有三种科学探索的动机:“在科学的庙堂里有许多房舍,住在里面的人真是各式各样,而引导他们到那里去的动机实在也各不相同。有许多人所以爱好科学,是因为科学给他们以超乎常人的智力上的快感,科学是他们自己的特殊娱乐,他们在这种娱乐中寻求生动活泼的经验和雄心壮志的满足;在这座庙堂里,另外还有许多人所以把他们的脑力产物奉献在祭台上,为的是纯粹功利的目的……对于这些人来说,只要有机会,人类活动的任何领域他们都会去干;他们究竟成为工程师,官吏,商人,还是科学家,…

论空间权

空间权是一种新型权利,空间权法理是传统土地所有权理论的新发展。空间权与土地权利的关系密切而复杂,准确恰当地定位两者的关系是空间权研究的核心问题。
