入境旅游目的地城市的旅游意象评价指标体系研究——以北京和上海为例

本文以北京和上海两个一级入境旅游目的地城市为案例地,构建了包括入境旅游者对旅游资源和旅游商品的兴趣度、对旅游服务质量和对整体旅游环境氛围的评价的入境旅游目的地城市的旅游意象评价指标体系。该体系运用极小极大离差法进行指标的筛选,并应用变异系数法进行指标权重的确定。将所采集的北京和上海的数据代入该评价体系进行计算后发现,上海的总得分高于北京。     

基于多因素综合评价法的城市土地定级评价研究——以银川市为例

多因素综合评价法能全面考虑各种与土地质量直接相关的因素,不仅包含了影响土地价值的经济因素,而且包含了其他因素。本文在分析已有文献的基础上,构建了针对城市土地综合定级评价的指标体系,运用特尔斐法结合方差和均值修正确定指标体系权重,选取银川市建成区的六个样本点,结合多因素综合评价法进行了实例分析,通过对评价结果进行分析,可知分等定级结果符合银川市城市发展建设的实际情况。     

多卷书的著录与标引问题探析

由于多卷书自身的特点及复杂性,在采用CNM ARC格式进行机编著录时会产生许多问题,从而会影响书目资源的共享。对此本文进行了有益的探索,即各分卷共用一个ISBN的多卷书应采用整套著录法,各分卷有独立的ISBN的多卷书应采用分卷著录法;多卷书的分类标引和主题标引均应整套集中标引。     

ANTAEUS Project for the Regional Vulnerability Assessment of the Current Building Stock in Historical Centers

This article presents a methodology for the seismic vulnerability assessment of current buildings, suitable for the study of historical centers at the regional scale. The applicability is demonstrated with reference to four case studies: the historical center of the city of Foggia (Italy) and three other small towns of this province, for a total of 4519 housing units. Field data were collected by several teams of technicians by means of a survey form, provided in electronic format. The subsequent data processing and drawing of vulnerability maps was performed using geographical information system (GIS) technology. The collected data were used also for the validation of the algorithm, by comparing the results with those of the methodology used by the Gruppo Nazionale per la Difesa dai Terremoti (GNDT [Italian National Group for Defense Against Earthquakes]), which is widely adopted in Italy. The results of the research study and the application showed some critical points, related to the poor nature of the information collected and to the reliability of the final results. These issues are analyzed and discussed, proposing a strategy for improving the methodology.     

Of resilient places: planning for urban resilience

This paper argues that resilience of a place cannot necessarily be associated only with the level of its vulnerability to the environment or security. A place-based perspective to resilience helps understand the capacity of communities to withstand or adapt with change. Resilience of a place does not only refer to contingencies—such as formulating immediate responses to crisis situations or incidents such as earthquakes, floods or other disasters in vulnerable areas—but also considers long-term mitigation and adaptation strategies to face social, economic and environmental challenges. To this purpose, the paper applies an evolutionary resilience framework to the case of Transition towns in the UK as resilient places in terms of their capacity for learning, robustness, ability to innovate and adaptability to change. In conclusion, socially innovative actions and initiatives are found to be a primary source of resilience through bottom-up creativity among communities and stakeholders to help improve social relations, support socio-political empowerment and fulfil the basic needs of the people.     

女性老年人肥胖的建成环境影响因素及规划响应研究

随着老龄化的快速发展,老年人在中国已经构成重要的群体,而因肥胖导致的一系列慢性疾病严重影响老年人的寿命和生命质量。身体质量指数（BMI）是衡量肥胖的重要指标。本文以女性老年人为研究对象,运用有序多分类Logistic回归模型,分析建成环境对女性老年人身体质量指数的影响。结果表明,居住地附近是否有适宜的休闲体力活动场所、居住地到休闲体力活动场所的步行时间、一周内去商场的频率、高热量食物的可获得性等建成环境变量与因变量女性老年人BMI等级存在显著联系。根据研究结论,从城市规划的角度提出建成环境优化建议,为构建老龄友好型的健康城市提供基础。     

The role of the past in late medieval hidalgo historical writing and memory

ABSTRACT

This essay is structured around two themes: the writing of history and memory. On the one hand, it analyses the use of the past in Lope García de Salazar's Libro de las buenas andanças e fortunas (1471–5). His approach to history is imbued with nostalgia for a legendary past, and more specifically for a political arrangement between the Lord of Biscay and the lesser nobility (hidalgos) which ensured respect for their privileges. This is set in contrast to a second group of material, legal documentation relating to the town of Escalante in Cantabria. Historically under seigniorial control, the inhabitants created a collective memory that framed a past prior to the fourteenth century which was free of lords and feudal obligations.     

《晋书·地理志》县级封国考论

反映西晋前期政区全貌的《晋书·地理志》中记载了58个县级封国,包括公国、侯国两类。虽然西晋朝廷已设置公、侯、伯、子、男五等爵,但这些封国所对应的爵位,却是位在五等爵之下的一般县公、县侯。各家县公主要是由曹魏宗王降封而来。为县侯者,有功臣、敌国降将、曹魏宗室,还有不少是曹魏时即已受封而入晋后仍保留爵位者。     

Brachiopods of the Yarralumla Formation (Ludlovian), Canberra,Australia

The Yarralumla Formation of Canberra has been considered the stratigraphic equivalent of the earliest Ludlovian Yass Formation of the Yass Syncline north of Canberra. The previously unpublished brachiopod fauna of the Yarralumla Formation is fully described; comparison with that of the Yass Formation confirms approximate age equivalence. Of the eleven species, none of which is new, eight also occur in or a little above the Yass Formation.     

INSTANTANEOUS OPTIMAL CONTROL FOR SEISMIC ANALYSIS OF NON-LINEAR STRUCTURES

In this paper, an effective active control algorithm is developed for the vibration control of non-linear structural systems subjected to earthquake excitation. It is an attempt to include the non-linear characteristics of the structural behaviour throughout the entire analysis (design and validation), accounting for the eventual cumulative structural damage and energy dissipation. This is a very important factor since, in current design practice, structures are assumed to behave nonlinearly when subjected to strong ground motion. The proposed algorithm focusses on the instantaneous optimal control approach for the development of the control algorithm where the nonlinearities are brought into the analysis through a non-linear state vector and a non-linear open loop term. A performance index that is quadratic in the control force and in the non-linear states and is subjected to a non-linear constraint equation, is minimised at every time step. The effectiveness of the proposed non-linear instantaneous optimal control (NIOC) strategy is critically evaluated in comparison with currently available active control techniques. Numerical simulation results indicate that the proposed approach provides a significant reduction of the peak response quantities, such as maximum response deformation, maximum response acceleration, ductility of the system, associated with a reduced maximum control force.
