西夏榷禁制度渊源考

西夏榷禁制度与唐、五代、北宋的榷禁制度关系密切,西夏"巡检"、"三司"、"栏头"、"群牧司"之名移植自五代、北宋。西夏榷盐价格基本与第五琦榷盐改革后税率相仿,榷盐根据不同产地、不同品种定价沿袭自五代定规;西夏榷曲告赏法借鉴自宋,收税职吏"栏头"与北宋后期的栏头更为接近;西夏畜牧榷禁中注籍、号印、禁杀牲畜规定的渊源可溯自唐代。总体而言,北宋榷禁是西夏榷禁制度的主要渊源。     

水—社会领域视角下的国际河流治理

国际河流的经济、社会、生态等多重属性使之成为重要的地缘政治议题。现实主义和制度主义分析容易陷入“领域陷阱”，难以充分呈现中微观层面的多元主体互动以及权力结构和自然要素的相互塑造过程。本文在政治地理学辩证性和关系性的思维基础上，介绍“水—社会领域”概念框架的基本特征及其在国际河流治理中的运用。该框架从权力—空间关系的视角出发，包含多元尺度、多维空间、关系网络和领域建构等分析维度。研究认为，国际河流治理是领域（再）生产的过程，水资源是治理过程不可分割的组成部分，自然与社会具有相互建构的辩证关系。将政治地理学的核心概念“领域”运用于水治理研究中，重新建构本体论和认识论，对国际河流治理的地缘关系解析具有独特的地理学价值和意义。     

长三角企业经营管理人才空间分布及其地理流动网络——基于上市公司董监高团队数据分析

在全球化与知识经济时代的双重背景下，人才尤其是高端人才已然成为衡量区域创新能力与经济发展水平的重要指标，其空间分布与流动趋势开始引起学术界的关注。基于人才履历大数据，应用履历分析、社会网络分析与修正型复合指标划分方法，对长三角地区企业经营管理人才空间分布及其流动网络进行了探究。结果表明：①企业经营管理人才空间分布具有明显地域差异，主要集中于沿海沿江地区，且空间集聚态势日益强化；②企业经营管理人才流动网络结构层级显著，网络链接空间上呈“Z”型分布；人才流动整体呈现出低流动性、“一主四副”结构、集中性、均衡性、极核交互与邻域渗透、跨区域性6大特征；③结合流动方向与活跃程度划分出四种人才流动地域类型，总体呈“破碎化”特征。为合理制定城市人才政策、促进区域高质量一体化发展提供科学借鉴与参考。     

秦系与泉州九日山

唐代著名诗人秦系与泉州九日山之间有密切关系,他为九日山留下丰厚的历史文化遗产。秦系曾两次隐居九日山,第一次为建中元年(780年)来,建中三年或四年离开;第二次为贞元七年(791年)至八年之间来,元和元年(806年)离开。在隐居九日山期间,秦系进行诗歌创作和注《老子》,与薛播、姜公辅、席相、欧阳詹、僧明惠等人有交游。九日山上与秦系相关的史迹,作为重要的历史文化资源,具有史料价值、教化价值和旅游价值。     

Visitors' wayfinding strategies and navigational aids in unfamiliar urban environment

Abstract

The way visitors to a new city wayfind in the digital era has been given less research attention than might be expected. The main aim of this study is to examine differences in wayfinding strategies between three groups of participants who used different navigational aids: a group with a paper map, a group with the Google Maps app, and a group relying on local signage only. Methods included GPS tracking, and voice recording of decision-making using the think-aloud method. 38 participants who had never visited Brisbane, Australia, were recruited and placed in one of the three groups. They undertook a two-hour pedestrian wayfinding task and other research activities in the city centre. The results show there are significant differences in wayfinding strategies used by the three groups of participants. The GPS group preferred to follow the suggested route by their navigator, most of them ‘locking in’ as digital navigators throughout the task. By contrast, the local-signage-only group used a diverse range of strategies to wayfind. Local-signage-only and paper map users tried to locate their position in the city by using piloting or path integration strategies, the GPS group just passively followed the guidance line showed by their device. On completion of the task the digital navigators recognized less spatial information. Surprisingly, the digital navigators did not feel less anxious compared with the two other groups. Urban planners and designers may need to re-think their design strategies to interrupt digital navigation. The provision of a more diverse set of digital navigation options, rather than just shortest-path route identification, is likely desirable to assist navigators who wish to experience more on their pedestrian journeys.     

欧阳修论考史

欧阳修在长期从事文献史料的收集、整理和研究工作中,始终能够坚持创新与求实并重原则,在考史方面得出了一些新的观点和认识,即:考史应"不没其实",力求史实真相;"慎于传疑",不轻易下结论;"勇断不惑",敢于创发己见;"不苟立异",反对刻意标新;"切于人事",排斥天命神学,这些至今仍具有方法论的意义。     

Checking Executive Power: A Simulation Model of Unilateral Executive Behavior

Abstract

What systematic influence does the court exert on unilateral authority? Though questions relating to the expansion and the exercise of unilateral executive power remain a perennial concern in political science, existing studies of the unilateral presidency generally focus on relations between the executive and the legislature, with less attention paid to the impact of the judiciary on executive behavior. Using a system of differential equations to model executive unilateralism and judicial constraints, simulation results identified four broad patterns of unilateral executive behavior and judicial influence. Overall, presidents strategically anticipate reactions from the courts and employ unilateral actions accordingly. Although they are cognizant of the court’s ability to strike down their actions, and thereby harming their preferred policy preferences and legacies, presidents nonetheless act unilaterally, albeit at a lower level. Results add to existing studies in separation of powers and constraints on unilateral executive behavior.
