国家权力、企业家精神与企业经营——以通用机器有限公司(1946~1949)为例

通用机器有限公司是国民政府资源委员会在抗战胜利后创办于上海的国有机械制造企业。资源委员会委派私营企业家马雄冠作为公司负责人,并肯定了马雄冠的"纯商业化"经营路线,使公司能边基建边投产运营,缓解了资金压力,在恶劣的局势下取得较好的成绩。尽管马雄冠为公司注入了企业家精神,但公司的销路问题有赖于资源委员会的重工业建设,其技术引进也由资源委员会负担了大笔先期资金,因此,该公司的成功是良好政企关系的产物。

Quantifying Animal Trajectories Using Spatial Aggregation and Sequence Analysis: A Case Study of Differentiating Trajectories of Multiple Species

The increasing availability of telemetry data with high spatial and temporal resolution promises to greatly advance scientific understandings of the movement patterns of individual organisms across space and time. The amount of data provided by such methods, however, can be challenging to analyze and interpret. In this study, we present a new approach for analyzing animal movements that aggregates telemetry locations into spatial clusters and extracts the information from sequences formed by individuals passing through these spatial clusters. We applied this integrated approach of spatial aggregation and sequence analysis to quantify and compare trajectories of cattle (Bos taurus), mule deer (Odocoileus hemionus), and elk (Cervus elaphus) tracked by automated telemetry at the Starkey Experimental Forest and Range in northeastern Oregon, USA. Our approach effectively differentiated movement patterns of the three species. It provides a useful mean of quantifying movement patterns of species in a landscape.     

全球—地方视角下西安市软件产业集群的创新效应研究

全球—地方关系为产业创新研究提供了新的视角。本文基于全球（通道）—本地（蜂鸣）关系视角构建了软件产业集群创新效应研究的理论框架。以西安市软件产业集群为例,采用Stata13定量分析不同尺度创新合作的创新效应及其影响因素。研究发现,本地和国际创新合作均对集群创新具有积极的影响,且后者比前者的创新效应更强,说明搭建外部通道对集群创新的必要性;本地与国际创新合作交互对不同规模的软件企业产生的创新效应不同,对小型软件企业存在减法效应,对中型软件企业存在加法效应,对大型软件企业具有乘法效应。建立领先软件企业带动的开放创新系统,是西安市软件产业集群提升创新效应的有效路径。

Sino–American relations: new changes and new challenges

Sino–American relations encompass a highly complex array of cooperative and competitive dimensions. Recently, they have evolved around the question of ‘China's rise’ or (as Chinese analysts would state it) ‘peaceful evolution’. This article surveys both the cooperative and competitive structural elements of this important bilateral relationship. It tracks recent transitions in that relationship, arguing that China's new-found status as a ‘responsible stakeholder’ in American eyes will present a new set of American expectations and new forms of strategic collaboration that will seriously test both sides’ policy creativity and ability to adapt to a rapidly changing global environment.     

高光谱成像技术在中国古代书画分析中的应用研究综述

中国古代书画，因其年代久远，递藏情况复杂，多数屡经裁切割补、修复重装，故而有很多历史信息或被叠摞或被遮蔽，导致今人不能以肉眼直接观察而获得，而纸绢接补，墨迹、颜料、印鉴的残损也为书画研究者带来诸多悬而未决的问题。近年来，高光谱技术作为一种非侵入式的光谱成像技术，已逐步应用于各类彩绘文物中，该技术可为中国古代书画研究和保护提供更丰富的信息。本工作以文献调研为基础，简要介绍了高光谱成像的原理及技术特点，对高光谱技术在中国古代书画研究的实践进行总结，梳理了国内外研究者利用高光谱技术在书画、档案及相关彩绘文物的增强显示、物质识别、虚拟修复方面的应用案例，以期为相关研究者提供参考借鉴。     

西夏语“头项”词义考

以往学界认为有关西夏汉文文献中的"头项"意为"头领、首领",也是西夏的一种军事组织,这一认识并不准确。传世汉文西夏文献中的"头项"乃是"头绪、种类"等义,而西夏文文献中的"头项"则是"事宜、事项"的意思,可以用作"同位语"。同一常用词在夏汉文本中词义的不对等,说明西夏语在词义衍生的思维模式层面与汉语是不一致的。     

Wealthy-gentry politics: How are capitalists in China chosen for the ‘Houses’?

Choosing individual private entrepreneurs to be members of the People's Congress (PC) or the Chinese People's Political Consultative Conference (CPPCC) is one of the most important mechanisms for ‘cooperative capitalism’ in China. This article aims to answer two questions: First, what are the differences between factors for winning a seat at the PC and a seat at the CPPCC, respectively? Second, is there any difference between factors that have a significant impact on winning a seat at the county-township level and the prefecture-and-above level of the PC or CPPCC? Based on empirical findings, I have coined the term ‘wealthy-gentry politics’ to conceptualise the fact that behaving as a member of the socially responsible ‘gentry’ plays an increasingly significant role at the higher level and in the PC compared to the lower level and the CPPCC, while economic wealth is just a threshold and party membership is not a guarantee.

挑选私营企业家个体进入两会是中国“合作型资本主义”的一个最重要机制。本文回答两个问题。1）获得人大代表的因素与获得政协委员的因素有何区别？2）获得县镇级两会代表和地级以上两会代表的影响因素是否有区别？ 根据实证研究,笔者发明“财—绅政治”的概念来描述一个事实：负有社会责任的社会贤达在高一级的人大较之低一级的政协发挥了越来越大的作用,财富仅仅是门槛,党籍也不起决定性作用。     

Estimating the number of components in an OSL decay curve using the Bayesian Information Criterion

The optically stimulated luminescence (OSL) decay curve is assumed to consist of a number of first-order exponential components. Improper estimation of the number of components leads to under-or over-fitting of the curve under consideration. Hence, correct estimation of the number of components is important to accurately analyze an OSL decay curve. In this study, we investigated the possibility of using the Bayesian Information Criterion to estimate the optimal number of components in an OSL decay curve. We tested the reliability of this method using several hundred measured decay curves and three simulation scenarios. Our results demonstrate that the quality of the identification can be influenced by several factors: the measurement time and the number of channels; the variability of the decay constants; and the signal-to-noise ratios of a decaying component. The results also suggest that the Bayesian Information Criterion has great potential to estimate the number of components in an OSL decay curve with a moderate to high signal-to-noise ratio.
