基于居民出行大数据的我国都市圈识别及其分布格局

都市圈是大城市发展到一定阶段的产物,当前都市圈空间范围界定还存在争议,本文梳理了都市圈的概念和内涵,采用手机信令出行数据识别了全国都市圈的空间分布格局。分析发现,我国大部分都市圈仍处于发育阶段,当出行率阈值为 1% 时全国识别出 27个都市圈。都市圈的分布格局与经济发展水平密切相关,经济发达地区的都市圈数量多、分布密集,如东部沿海和城市群地区。中心城市的人口和经济规模,以及圈域出行距离影响了都市圈的空间范围和圈内联系程度,圈域出行规模与中心城市人口规模呈正相关,外围城市向中心城市的出行率与中心城市经济首位度呈正相关,且符合距离衰减规律。     

雾霾天气对国内游客旅游意愿与行为影响研究——以西安为例

在雾霾天气频繁影响旅游业发展背景下,本研究以西安为案例地,基于问卷调查数据,综合运用统计分析与卡方检验方法,从旅游前、旅游中、旅游后三个阶段,系统探究雾霾天气下国内游客的旅游意愿、行为特征、影响因素与形成机理。结果表明：在当前旅游发展阶段,受旅游机会、成本等因素影响,国内游客普遍对旅游城市雾霾天气影响重视不足,且不同旅游阶段游客旅游意愿与实际行为之间存在较大偏差。同时,游客对旅游城市雾霾天气的响应特征具有极强的内在关联性,且游客对雾霾的关注率、知晓率和游后意愿行为等均受其婚姻状况显著影响,而与其惯常生活环境无关。     

斯坦因1393号文书《晋书·列传》残卷跋

斯坦因一三九三号文书是《晋书》列传第十七、十八、二十、二十四的简编和节略本子,卷中保存了傅玄、傅咸、傅祗、傅宣、向雄、段灼、阎缵、庾峻、庾珉、庾敳、庾纯、庾旉、郭象、陆机等十四人传记,但均极简略。卷中"世"、"民"缺笔,且避"诏"讳,但不避"旦"字,推测应抄写于武后统治时期。     

城市化对典型省际区域旅游业产业效应的实证研究:1996-2008——以江苏、河南和陕西三省为例

选取我国三个典型省际区域作为研究案例,并将城市化对旅游业的产业效应分为城市化对国内旅游、入境旅游和整体旅游发展的三种产业效应进行实证分析,发现区域的差异性也表现出了城市化对旅游业不同的产业效应,主要表现为三省国内旅游、入境旅游和整体旅游发展分别与本省城市化发展存在着相互不同的协整关系.此外,本文还通过对三省整体面板数据计量模型回归,定量分析了城市化对三省整体旅游业的产业效应.文章进一步对产生上述现象的原因进行了分析,并提出了相关政策建议.     

JIN ZHIGUO AND HIS TIBETAN KNIVES

On a sunny afternoon,40 years ago,several Tibetan herdsmen were sitting cross-legged and dice in the yard of a Tibetan-style inn situated to the east of the Potala Palace.A teenage Han Chinese boy walked up to them and his eyes were drawn to a shining knife half-hidden in the leather Tibetan robe     

权力精英结构的饮食表达——基于清代“满汉全席”发明的微观政治学分析

在清代特有的部族政权统治下,满族统治者通过其内部精英的凝聚力和满汉文化之间的相互渗透,强化了封建中央集权,发挥了国家政治行动的力量,维护了满族统治者的特权和利益。在这一系列的政治行为背后,满汉全席这一筵席形式应时出现,并在满族统治者的政治运行过程中发挥着不可替代的作用,作为一种主观构建的筵席仪式,其变化过程表达着满、汉精英之间的权力争夺,体现着清代权力精英结构的变化。     

陕西省几座唐墓壁画白灰层的特性研究

为了研究唐墓壁画白灰层的特性,本研究以乾陵等7座陕西唐墓壁画的白灰层为研究对象,使用超景深显微镜、扫描电子显微镜、X射线衍射仪、热分析仪和万能材料试验机测试了样品的显微结构、物相、无机物和有机物含量以及力学强度,并探讨了影响白灰层疏松程度、强度的因素。实验结果表明白灰层主要由无机物组成,包括碳酸钙、二氧化硅和锰白云石,平均含量88.71%,有机物平均含量9.33%。白灰层厚度一般为3~5mm,平均孔径约1.77μm,总孔数大致为7920个/mm2,平均抗折强度约0.96MPa。无机物与有机物含量比与疏松程度呈反相关性;疏松程度与强度基本上呈反相关性。小孔径、低含水率、锰白云石可能会增大白灰层的强度。该工作深化了唐墓壁画白灰层的研究,为后期寻找更合适的渗透加固材料、工艺奠定了科学基础。     

The Effect of Persuasive Messages on Policy Problem Recognition

Prior theories of individual behavior in recognizing public problems have centered on the role of policy entrepreneurs; institutional effects; information; and cultural, political, and social pressures. Our extension of these theories suggests that policy problem recognition is an attitudinal evaluation process. If the information is considered valid and the new attitude is negative in valence, then a policy problem is recognized. To test this theory, we use an embedded experiment in a national survey to measure the effect of persuasive messages on the concern for global warming. We find that the negativity of the message and the credibility of the source of the message both affect the level of increase in concern for global warming. Further, the impact of the message from the source is conditional based upon the recipient's ideology. This suggests that policy problem recognition is attitudinal and thus incorporates both analytical and affective components.     

Sticking to the Stand of Chinese Culture and Promoting Cultural Self-Confidence and SelfImprovement

Sticking to the stand of Chinese culture is the basic premise of promoting cultural self-confidence and self-improvement. Only by thinking rationally about the inheritance, borrow-in, development, and promotion of culture can we grasp the essence of sticking to the stand of Chinese culture. To inherit the traditional culture, we should combine the new practice with the requirements of the times and take its essence while discarding its dross. The key to learning from foreign cultures is to give priority to ourselves and use them for our purposes. We can not swallow it all down and blindly use it. To develop socialist culture, we should, on the one hand, respect the national cultural tradition and on the other hand, constantly innovate and create a new culture. To carry forward Chinese culture, we need to meet the people’s growing spiritual and cultural demands internally and strengthen the influence of the spread of Chinese civilization, promoting Chinese culture to the world.     

商品链视角下K-pop偶像的生产—消费政治研究

本文引入 Sack 的道德地理相关理论,从商品链中生产与消费节点的地方—道德维度,考察 Kpop 偶像商品链中生产与消费节点间的互动机制。研究表明：①新自由主义理念构建下的地理要素促进了K-pop偶像产业的高效运转,但阻碍了 K-pop练习生的差异化与多元化发展,因此具有消极的内在地理特征。②媒介营造了 K-pop 偶像后现代性的消费场景,满足了消费者对于空间情境、寻求认同以及创造意义的需求,但其对生产地事实的掩盖使得消费空间丧失了地方真实性与复杂性,呈现单一、割裂的内在地理特征。③K-pop偶像的生产与消费景观作为积极的工具道德地理景观促进了商品链的高效运作与循环,但其生产与消费互动具有消极的内在地理特征,不利于人们对客观世界的感知。
