洛林吉亚国王罗退尔二世离婚风波迭起的历史动因

基督教会提倡"婚姻不可分解"的理念,这种理念随着基督教会势力的壮大和宗教思想的深入人心,对中世纪西欧封建帝王的婚姻构成了一种道德约束作用。而罗马教延等现实政治生活中的各方势力也常常以此为由,向那些有违婚姻道德的世俗帝王问责发难。洛林吉亚王国的国王罗退尔二世的离婚案即是一起因此而发的政治风波。由于基督教婚姻理念的约束作用,加洛林帝国的分裂瓦解、同宗诸王的纷争内斗、教皇权威开始抬头等众多历史因素的叠加、交织,使得罗退尔二世不仅无法像他的先祖查理曼那样可以自由地离异,反而成了众矢之的,最后以"身死国灭"的历史悲剧黯然收场。     

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.     

On evolutionary economic geography: a literature review using bibliometric analysis

During the past few decades, there has been growing attention paid towards evolutionary economic geography (EEG) perspectives, methodologies, and concepts in various disciplines such as geography, urban studies, and regional science. In order to better understand the development of EEG studies, this paper employs multiple bibliometric analyses. Specifically, it examines the temporal evolution of keyword co-occurrence network and the reference co-citation network of EEG publications during the last few decades to reveal the temporal evolution and spatial distribution of EEG publications, scholarly communication, research fronts, and intellectual structure of the scientific field.     

Rejoinder to Professor Ho’s team on the article entitled ‘On evolutionary economic geography: a literature review using bibliometric analysis’

Professor Ho’s team has raised three questions about our paper entitled ‘On evolutionary economic geography: a literature review using bibliometric analysis’ published in European Panning Studies. The first one is about the number of articles in our search results. The second one is about the databases we have used in the Web of Science system. In the last comment, Professor Ho suggests a new searching strategy – ‘front page’ rule. We have responded to those three comments one by one in this rejoinder.     

地方发展变迁与居民地方感关系研究——以广州荔枝湾涌历史文化街区为例

本文以广州荔枝湾涌历史文化街区为例,运用扎根理论研究荔枝湾涌1940年代以来地方发展变迁与居民地方感的关系,进而挖掘居民地方感变化机制。研究发现：荔枝湾涌居民的地方感主要受生态环境、建筑与配套服务、集体记忆、活动类型、人际关系等因素的影响,其中生态环境起主导性作用;积极地方感主要来源于集体记忆的保留与延续;消极地方感主要来源于破旧的居住环境及落后的配套服务;此外,文章提出内向型地方感和外向型地方感的概念,认为随着城市发展,在地方发展变迁过程中,地方感由内向型地方感转变为内向型和外向型相结合的地方感。两种地方感相互作用,互相调节,更有利于地方稳定、开放、包容地发展。     

Lichenometric constraints on the age of the Huashan Grottoes, East China

Lichenometry is a method of dating that has been widely used in glaciated areas for determining the minimum age of exposure of a geomorphic landform during the late Holocene. This paper presents a regional calibration data set of lichen thallus sizes versus rock surface ages for the Huashan area, East China, based on measurements of yellow-green Rhizocarpon lichens on the known-age substrates at eight sites. An empirical relationship between thallus sizes and rock surface ages was established using both the traditional regression and the Bayesian approaches. Using the Bayesian calibration, the minimum age of the Huashan Grottoes was dated from 450 ± 60 to 330 ± 60 years ago, corresponding to the late Ming Dynasty (AD 1477–1632). These dates are generally consistent with those predicted from the regression-based linear growth curve. Our results suggest that applications of this technique can be safely extended to the non-glaciated areas.     

从“公推”到“票举”：近代天津商会职员推选制度的曲折演进

近代中国具有现代意义的投票选举制度虽然率先在清末的民间工商社团商会中实行,但各地商会的具体实施过程却并非同步进行。上海、苏州等商会正式成立后即开始制订并实行这一制度,天津商会则在清末坚持采用"公推"的方式推举总理、协理和会董,没有真正实施"票举"。到民国初期,天津商会依然认为"公推"优于"票举",直至明定商会必须实行投票选举制度的《商会法》公布之后,天津商会还希望政府"准予特殊办法,仍行公推"。但实施"票举"在当时已是大势所趋,1918年天津商会也在章程中拟订了投票选举制度,并由此进入"票举"会长和会董的新时期。自清末至民国时期天津商会从"公推"到"票举"的曲折演进历程,说明在选举制度的建设中,天津商会的领导人在思想认识和实践操作两个方面都偏向于保守,不仅自身缺乏创造性的举措,而且很少主动借鉴和学习其他商会已有的投票选举制度,这种现象也表明了清末民初各地商会对现代投票选举制度的认识并不完全一致。     

里耶秦简"金布"与《周礼》中的相关制度

本文把里耶秦简中有关"金布"的史料与《周礼》中的相关记载作了比较研究,发现里耶秦简的记载与《周礼》之间在史料上存在着继承与发展的关系.里耶秦简的记载更加制度化,更加细致,而《周礼》的记载则显得比较简略、分散,比较原始.这一研究,不但有利于对《周礼》史料的理解,而且对战国到秦汉社会制度的发展的探讨有重要意义.     

岭南建筑民俗中的易学思想

岭南近现代建筑具有独特的民俗风情,自成一套完整的解释系统,甚至可以说,是较早把现代建筑思想与中国传统文化进行结合的标本。从开平雕楼到客家围龙屋,     

1992年以来我国城镇居民居住消费的变化趋势

1992年之后,我国明确了建立社会主义市场经济体制的目标,城镇住房制度改革取得了实质性突破,城镇居民居住消费发生了深刻变化。居民购房公平自由,私有住房的比重急剧攀升,住房设施日益完善,居住环境不断优化,居住开支迅猛增长,城镇居民居住水平获得了前所未有的提高。然而受不正确的思想观念的影响,在居民居住消费过程中,一些诸如住宅私有率过高、住宅面积过大、一房伴终身等严重脱离实际需要和基本国情的问题日益突出。
