近年来,随着我国港口资源整合、港区功能调整和港口城市的转型升级,沿海港口与所在城市的关系发展面临新的变化和挑战。本文以我国沿海港口为例,结合定量分析与定性讨论,聚焦我国沿海港口港城关系问题,剖析港城关系的演变及驱动机制。研究发现:我国大部分沿海港口已进入极度协调发展阶段,但发展趋势逐渐放缓,区域分化特征显著,港城协同度差距呈现再扩大的发展趋势。在研究期间,我国城市驱动型港口城市数量显著增加,港口驱动型和港城互驱型港口城市数量减少。建议通过政府政策引导、港产城融合发展和港口转型升级等方式,不断提升我国沿海地区港城关系整体协调发展水平,为新时期我国沿海港口与所在城市的高质量发展提供重要支撑。  相似文献

In this paper, I suggest that the category of ‘ward,’ a designation used for Aboriginal Australians in the 1950s and 1960s, has re-emerged in contemporary Northern Territory (NT) life. Wardship represents an in-between status, neither citizens nor non-citizens, but rather an anticipatory citizenship formation constructed by the Australian state. The ward is a not-yet citizen, and the deeds, acts, and discourses that define the ward's capacities to act as a political subject can maintain their anticipatory nature even as people ‘achieve’ formal citizenship. Wardship can be layered on top of citizen and non-citizen status alike. Rather than accounting for the grey areas between ‘citizen’ and ‘non-citizen,’ therefore, wards exist beyond this theoretical continuum, demanding a more nuanced accounting of political subjectivities and people's relationships to the state.I trace the emergence of the category ‘ward’ in the 1950s and 1960s in Australia and its re-emergence for Aboriginal Australians impacted by the 2007 Northern Territory Emergency Response legislation. The promise of citizenship offered by the status of ‘ward’ is built upon expectations about family life, economic activity, and appropriate behaviour. These assumptions underscore an implicit bargain between individuals and the state, that neoliberalised self-discipline will lead to both formal citizenship rights and a sense of belonging. Built-in impediments, however, ensure that this bargain is difficult, if not impossible, to fulfil.  相似文献

The extent to which North Atlantic Holocene climatic perturbations influenced past human societies is an area of considerable uncertainty and fierce debate. Ireland is ideally placed to help resolve this issue, being occupied for over 9000 yr and located on the eastern Atlantic seaboard, a region dominated by westerly airflow. Irish bog and lake tree populations provide unambiguous evidence of major shifts in surface moisture through the Holocene similar to cycles recorded in the marine realm of the North Atlantic, indicating significant changes in the latitude and intensity of zonal atmospheric circulation across the region. To test for human response to these cycles we summed the probabilities of 465 radiocarbon ages obtained from Irish archaeological contexts and observe enhanced archaeological visibility during periods of sustained wet conditions. These results suggest either increasing density of human populations in key, often defensive locations, and/or the development of subsistence strategies to overcome changing conditions, the latter recently proposed as a significant factor in avoiding societal collapse. Regardless, we demonstrate environmental change is a significantly more important factor in influencing human activity in the landscape than has hitherto been acknowledged.  相似文献

通过对上海及邻近地区地震危害性分析,结合地震研究工作结果,根据上海博物馆文物防震保护的具体要求,研究确定了该博物馆文物防震保护的设防水准及地震动参数。场地地震动输入峰值加速度水准确定为50年超越概率3%,地震动反应谱采用上海市标准《建筑抗震设计规范》(DGJ08-9-92)中给出的地震影响系数曲线(阻尼比0.05),并将输入峰值加速度调整为180gal。研究采用了目前通用的拟合反应谱的方法,通过拟合选定的地震动反应标准谱,合成了6条人造地震波时程曲线,拟合精度控制在相对误差不大于5%;同时结合上海市《建筑抗震设计规范》(DGJ08-9-92)中所附的一条强震记录,共同作为上海博物馆结构地震反应分析的输入地震动。又根据上海博物馆建筑的结构特征分析,结合建筑结沟动力特征的实测结果,通过采用层模型结构时程分析计算方法,计算并获得了在遭遇设防地震时,上海博物馆建筑物每一层的地震动反应,表明上海博物馆建筑各楼层的地震动反应具有明显的楼层放大作用。对各楼层地震动反应的统计分析,给出了上海博物馆建筑物每一层的地震动参数,以此可作为今后文物地震危害性分析,及研究设计隔震装置等防震措施的依据。  相似文献

A framework for quick seismic assessment and retrofit of traditional unreinforced masonry (URM) structures is presented. The proposed methods build on simple principles of structural dynamics and are used as an alternative to detailed time-history analysis, in recognition of the prevailing need for simple and practical methods, compatible with the low-budget and the limited level of knowledge regarding materials, internal force paths, connectivity and condition of older URM structures. An objective is to identify areas in the building that are particularly susceptible to damage and for guiding the types of the required global interventions to improve seismic response. Demand and supply are expressed in terms of relative drift ratios that quantify the intensity of out-of-plane differential translation and in-plane shear distortion of masonry walls. A characteristic traditional building type of timber-laced masonry is used as a model structure for illustration of concepts. The morphology and geometry of the building correspond to a statistical sample of the actual traditional unreinforced masonry buildings (TURM) found in historical centers of many towns in the greater region of Northern Greece. The methodology is particularly useful for setting retrofit priorities and management of the collective seismic risk of historical entities.  相似文献

This paper presents findings from a gendered analysis of resident responses to the 2009 Black Saturday bushfires (wildfires) in Victoria, Australia. One hundred and seventy‐three people lost their lives in the bushfires and more than 2000 houses were destroyed. Previous research on Black Saturday has largely focused on issues of resident preparedness and response, with limited consideration of the role of gender in household decisions and actions. This paper examines the gendered dimensions of risk awareness, preparedness and response among households affected by the bushfires. Data were collected through in‐depth interviews with over 600 survivors and a questionnaire of 1314 households in fire‐affected areas. Analysis revealed that women more often wanted to leave than men, who more often wanted to stay and defend property against the bushfires. Nevertheless, findings suggest that broad‐brush characterisations of staying to defend as a masculine response and leaving as a feminine response are misguided. Although some women expressed a strong desire to leave, others were resolute on staying to defend. Equally, while some men were determined to stay and defend, others had never considered it an option. Despite this, the research identified numerous instances where disagreement had arisen as a result of differing intentions. Conflict most often stemmed from men's reluctance to leave, and was most apparent where households had not adequately planned or discussed their intended responses. The paper concludes by considering the degree to which the findings are consistent with other research on gender and bushfire, and the implications for bushfire safety policy and practice.  相似文献

20多年来,旅游管理课程体系建设取得很大成绩,但依然存在课程老化固化、缺乏对社会需求响应能力等问题。通过往届毕业生、网络、新业态和旅游组织机构等多端口的职业需求信息的监测与评估,在理论和技术上可以构建一个既能响应社会需求,又能满足学生个人兴趣,还能符合国家专业要求的“三位一体”的响应社会需求的旅游动态课程体系。通过该课程体系的建设可以加强现有专业对社会需求的响应能力,减少一些短周期新专业的应急性增设,从而节约教育资源、积累教育资本、避免学生同业竞争、缓解就业压力。基于以上理论和实证研究,云南民族大学旅游管理专业未来至少可以增设美食与营养、旅游技术与工程两门课程以响应社会需求,并形成其核心竞争能力.  相似文献

This paper explores the perceptions of drought by residents in outback South Australia and their associated responses to the drought. Behavioural Geography methodology is used with data drawn from interviews with pastoralists, business owners, and residents of small outback towns and Aboriginal communities. Although they were not resident in the region, the perceptions of tourists were also garnered. The results show that perceptions varied between the groups of people interviewed. Outback residents contrasted their own frugal water use with reports of wasteful behaviour by foreign tourists. Local inhabitants were largely ‘accepting’ of the drought, having survived worse droughts in the past and over many years. They were therefore of the sentiment that they would cope with future droughts. Despite the sentiments of acceptance, the dropping groundwater levels and continued lack of rainfall were leading to growing concerns for the future. The concerns point to a boundary to community resilience to drought in outback South Australia.  相似文献

文章在分析河南省城市化发展阶段性特征的基础上,对城市化和产业结构之间的变动关系进行了对比分析、相关分析和回归分析,并用Arcgis9.3以"产业结构演变城市化响应系数"为指标绘制地图,反映了河南省城市化与产业结构之间作用强弱的空间差异,分析表明,河南省城市化与产业结构存在严重偏差,原因在于城市化与产业结构的非协调发展和产业结构与就业结构的不合理发展;河南省的产业结构演变城市化响应呈现"西高东低"、"北高南低"的地理分布特征。最后针对问题提出了对策。  相似文献
