游客出游意愿影响因素研究——基于突发公共卫生事件的实证

本文在目标导向行为模型的基础上,构建了游客在面对突发公共卫生事件时各种影响因素对出游意愿影响的理论模型,为系统性的进行影响游客出游意愿的因素研究奠定了基础。在对经历过突发公共卫生事件后有出游经历的游客进行实证研究后,发现出游态度、感知行为控制和积极的预期情感对出游欲望有显著的正向影响;消极的预期情感对出游欲望有显著的负向影响;出游欲望对出游意愿有显著的正向影响。     

台湾自由经济区演化及动力机制研究

随着经济全球化的深入发展,自由经济区在推动国民经济总体发展战略实施与经济体制改革、促进区域经济和城市化发展等方面发挥了重要作用。20世纪60年代,台湾建立了世界上第一个正式以"出口加工区"命名的经济型特区,通过不断转型升级推动了台湾的工业化和社会经济发展。本文通过文献归纳,总结了台湾经历的"出口加工区-科学工业园区-自由贸易港-自由经济示范区"四个发展阶段的特点;从目标、政策法规、管理、产业和空间结构入手,归纳出台湾自由经济区的形成演化规律;并认为要素、产业、效益、创新、政策、市场、环境各动力因素相互作用,构成推动其演化的动力机制。本研究对完善自由经济区形成演化理论探索和国内自贸区建设具有一定参考意义。     

东北地区资源型城市资源诅咒效应及传导机制研究

通过面板数据固定效应模型,利用东北地区23个资源型地级城市1999-2012年的数据,分析了东北地区资源型城市资源诅咒效应的存在性与主要传导机制。结论显示东北地区资源型城市存在资源诅咒效应;物质资本投资对经济发展起到最为明显的促进作用,制造业投入和教育业投入也具有一定的促进作用,但作用不够显著。城市开放程度与经济发展之间呈现负相关关系,而城市类型与经济发展不存在明显相关关系。传导机制方面,资源诅咒效应主要通过抑制制造业发展、物质资本投入和教育业投入来阻碍经济增长,其中对制造业的负面影响是主要传导因素。煤炭和石油型城市体现出较为明显的人力资本挤出,而其他类城市传导机制作用则比较平均。     

20世纪90年代以来封闭社区国内外研究述评

全球化与"新自由主义"背景下,封闭社区已经成为当代城市研究的热点问题,本文对20世纪90年代以来的相关文献进行梳理,以多重维度解读封闭社区的形成与发展之动力机制,探讨了全球化与后福特主义、新自由主义公共策略、公共选择与制度经济学、社会隔离与社会冲突、文化权力与空间等五种研究范式。根据市场、权力、居民群体三方力量的消长,可将诸类案例划分为自发推动、资本驱动以及自上而下三种。对于封闭社区与社会隔离的相关性问题,存在社会结构体制与个人行为态度两个层面的争论。在此基础上,本文对国内的相关领域研究提出了建议与展望。     

地理的空间与文学的意象——以贾平凹小说创作为例

人地关系对文学创作具有深刻影响。贾平凹其人其文在创作理念、叙事方式、人物形象等方面都具有鲜明的地域性特征。本文以贾平凹代表性小说作品为例,考量了商州的地域文化地理要素对贾平凹小说创作产生影响的机制。论文认为,自然地理环境能够构成文学创作的自然意象,人文地理环境能够生发文学创作的民俗文化意象、丰富其地域文化意象,并促成便于营造意象的艺术风格及其嬗变。     

Fluidized sandstone intrusions as an indicator of Paleostress orientation, Santa Cruz, California

The late Miocene sandstone intrusions of northern Santa Cruz County, California, are the largest subaerial exposures of clastic intrusions on earth. The intrusions are sourced from a sandstone, underlying mudstone, accumulated in an outer shelf to upper slope environment. Dikes are the most frequent intrusion type, reach the greatest thickness and tend to strike north‐east and dip steeply. One giant dike is more than 150 m wide. Sills are least frequent, locally > 8 m thick and have no clear preferred geographical distribution. Clustered intrusions are commonly < 10 cm thick and mostly composed of dikes of various attitudes. The majority of the intrusions probably were injected shallowly as some extrude onto the seafloor. The local seafloor extrusion also indicates injection during the deposition of the Santa Cruz Mudstone (7–9 Ma). The intrusions are concentrated at the basin margin. Fluid pressure at the centre of the basin and perhaps hydrocarbons were communicated to the basin margin through the then sand, causing fluid overpressures that contributed to the fluidization and intrusion into the overlying mudstone. Primarily north‐east‐striking, steeply dipping dikes and secondarily, shallowly dipping sills are most significant in terms of regional connectivity of intrusions and physical dilation of the formation. The orientation of the dikes and sills indicates a regional stress field with a horizontal NE–SW maximum and a NW–SE minimum compressive direction. The simultaneous development of dikes and sills suggests similar magnitudes of the minimum and intermediate principal stresses. Preferential weakness along bedding contributed to the development of sills. Palaeomagnetic data indicate no significant block rotation around a vertical axis. The maximum principal stress direction indicated by the intrusions is about 55° to the San Gregorio Fault and about 70° to the San Andreas Fault during the late Miocene. This stress field is similar to the modern stress field and suggests moderate fault weakness.     

Acheulean variability and hominin dispersals: a model-bound approach

Understanding the pattern of hominin dispersal is a fundamental component of Palaeolithic archaeology and palaeoanthropology. A widely held assumption is that bifacial handaxe (i.e. Acheulean or ‘Mode 2’) technologies evolved in Africa and dispersed into northern and western Eurasia via subsequent hominin migrations. To date, however, few formal tests of this hypothesis have been presented. Here, we use a combination of morphometrics, cultural transmission theory, and a dispersal model drawn from population genetics in order to test this hypothesis. The iterative founder effect (repeated bottlenecking) model is assumed to be supported if a significant inverse relationship is found between geographic distance from source along an estimated dispersal route and within-assemblage variance. The results of our analyses support the hypothesis that Acheulean technologies evolved in Africa and dispersed with migrating hominin populations into northern and western Eurasia under the assumptions of this iterative founder effect model. Based on our results we suggest that the occurrence of certain Mode 1 technologies such as those east of the Movius Line, and some assemblages assigned to the Clactonian of Britain, plausibly represent instances where effective population sizes in colonising populations dropped below levels where Mode 2 technologies could be maintained.     

Acheulean variation and selection: does handaxe symmetry fit neutral expectations?

It has been suggested that the property of symmetry observed in Acheulean handaxes was selected for functional, adaptive or social and aesthetic reasons. However, selectionist accounts of variation may be contrasted with the approach taken by population geneticists to molecular variation. Population geneticists always first assume a neutral pattern of variation for molecular data, and only look to non-neutral (e.g., selective) scenarios for pattern and variation in the face of strong evidence against this null model of neutral expectation. Here, using a combination of cultural transmission theory, morphometrics, and the principles of population genetics, (null) neutral expectations for Acheulean handaxe symmetry are tested. The results of the analyses are inconsistent with a null hypothesis of neutral expectation for patterns of handaxe symmetry variation. Rather, the results imply that the property of symmetry in Acheulean handaxes was subject to selection for functional, adaptive or social reasons.     

从施米特“权杖的前厅”看预防权力滥用

德国政治学家卡尔·施米特认为,“权杖的前厅”是权力的剩余价值的衍生物,这是一种非常渠道的政治参与,它具有依赖性和斗争性的根本特性以及多样化的外在表现形式。“前厅”的存在与人的本能以及掌权者的心理需要有着密切的关系,其弊端与危害表明这是一个必须割除的政治毒瘤。阻止“前厅”对政治的干预必须阻止权力的滥用,这就需要建立健全长效的教育机制以及监督和制约权力运行的自律机制和他律机制。
