假日旅游高峰对旅游生态环境的破坏及对策分析

假日旅游带来的客流高峰对旅游生态环境造成多层次、多方面的破坏,本文对此进行了较为详尽的分析,并从时间分流、客源分流、信息分流、价格分流和景区分流等角度,对解决假日旅游高峰问题提出建议和措施.     

美国城市旅游

美国城市旅游对我国发展都市旅游有借鉴意义。本介绍了美国在散客旅游方式、旅游交通、城市旅游资源开发、旅游宣传资料以及旅馆业经营方式方面的一些做法。     

旅游线路设计与优化中的运筹学问题

旅游线路设计问题是旅游规划研究中一个重要的问题,本文把运筹学的方法引入旅游研究,探讨旅游线路的优化设计问题。基于定量分析与定性分析相结合的认识,本文重点是展示运筹学方法、图论方法的应用潜力,而没有着力于具体的技术细节。     

国内旅游团利益相关者利益格局均衡发展模式探究

一直以来,很多学者和业内人士把国内旅游团＂旅游服务质量问题＂归结为导游的素质,并探索过多种改善途径,虽取得了一定成效,但仍未达到根本解决的目的.本文从＂利益相关者＂角度思考该问题,认为其症结主要在于各主体间利益关系的失衡,因此尝试通过构建国内旅游团利益相关者利益格局均衡发展模式来解决这一问题.     

基于健康视角的城市就业者通勤模式选择及影响因素研究——以南京市为例

中国城市出现的居住和就业"空间不匹配"现象,对就业者日常通勤时间和方式产生了重要影响,进而影响就业者健康状况。依托南京市居民身体活动和健康状况问卷调查数据,根据不同通勤方式身体活动量的大小将就业者的通勤模式分为积极通勤、公共交通通勤和机动车通勤三种,构建多项Logistic回归模型探究城市就业者通勤模式的选择及相关影响因素。结果表明:(1)就业者对自身健康的主观认知和客观身体健康状况以及是否散步等健康行为显著影响通勤模式的选择;(2)通勤时间、加班等与工作相关的变量与就业者机动车通勤显著正相关,雨雪天气与积极通勤显著负相关;(3)个体社会经济属性中性别、年龄、家庭人口规模以及是否拥有小汽车等显著影响通勤模式选择。基于研究结果,本文对如何引导就业者选择更加积极和可持续的通勤模式提出了政策建议。     

中国古代“飞蝗避境”现象记载与史家观念演变

"飞蝗避境"是始出于西汉末年史料记载中的一种特殊现象,关于其出现原因历来学界多有争论。笔者通过梳理自汉代后记载关于此现象的史料并分析发现,关于"飞蝗避境"现象记载的产生及发展是在基于一定客观现实状况下,史家观念受到汉代天人感应思想及谶纬学说的影响,而将此现象有意识的与良吏、德政相联系,最后发展成为史家记载良吏和贤德人物的固定书写模式。这一过程起于西汉末年,东汉迅速发展,至魏晋之际逐渐发展完善,转变为与"猛虎渡河""鸟雀集庐"等并存的史家书写模式。中唐以后,随着科学技术的发展及天命史观向天理史观的转变,"飞蝗避境"这一书写模式逐渐淡出了人们的视线。     

The Meaning of Things: Kipling’s Formative Journey ‘Home’ in 1889 and the Late Victorian Imperial Tour

The ‘seven years’ hard’ Rudyard Kipling spent as a journalist in north India are generally seen as the making of both his poetic and his politics. But, important as origin, community, identity and ‘my father’s house’ are to Kipling, he should also be seen as a wayfarer of no fixed abode. In 1889 he used his first royalties to return to metropolitan fame by the long way round: Burma, the Straits, Japan, the Pacific and a transcontinental journey past landmarks of his Americanophile boyhood reading. Both distressing and exhilarating, it was a journey that stimulated the productive tension in him between the parochial and the universal. If an upcountry Punjab station had impressed him with the necessity of colonial rule, it was this voyage that engendered his all-embracing imperial vision. If he had honed his eye for ‘local colour’, this trip intimated to him that his metier would lie in culturally translating disparate portions of the empire to one another. Anticipating Baden-Powell’s call to ‘look wider’, vagabonding proved to be an agreeable mode of existence, but metropolitan arrival was to hold its own unforeseen challenges and anxieties. At a time when English writers like Arthur Symons aestheticised their sensation of cultural rootlessness in the figure of the vagabond, Kipling sought to foreground his own vagabondism with a persuasive claim to belonging.     

中国国内观光旅游线路设计中的游时研究

旅游线路是旅行社销售的主要产品,也是目的地旅游开发和市场营销的重要对象,其中游时是旅游线路设计中的核心要素之一。本文通过对北京、上海和广州为旅游出发地的旅游线路的统计分析表明,在中国国内观光旅游线路设计中,游时(出游时间与游览时间的统称)随客源地-目的地之间的距离呈对数增长,其中出游时间T₀(一次旅游的总耗时,单位:天)与出行直线距离D₁(客源地与目的地之间的球面距离,单位:公里)之间具有方程T₀=-4.5769+1.31611n(D₁)所描述的统计关系,而游览时间T₁(游客在目的地逗留的时间,单位:天)与出行直线距离D₁之间具有方程T₁=-4.2188+1.1220ln （D₁）所描述的统计关系。研究还发现,旅行社每日安排游览的景区(点)数目具有随出行距离呈"U"型曲线的特点,平均而言,在目的地逗留期间每天安排游览的景区(点)约为5个;从交通方式上看,随着出行距离的增加,呈现出汽车-火车-飞机交替演变的特点;旅游报价P与出行直线距离D₁之间存在线性相关性,关系式为:P=293.81+1.184 D₁。     

MODELLING OF RC BEAM-COLUMN JOINTS AND STRUCTURAL WALLS

The deformation of beam-column joints may contribute significantly to drift of reinforced concrete (RC) frames. In addition, failure may occur in the joints due to cumulative concrete crushing from applied beam and column moments, bond slip of embedded bars or shear failure as in the case of existing frames with nonductile detailing. When subjected to earthquake loading, failure in RC structural wall is similar to failure of frame joints as it may occur due to cumulative crushing from high flexural stresses, bond slip failure of lap splice, shear failure or a combination of various mechanisms of failure. It is important to include these behavioural characteristics in a simple model that can be used in the analysis of RC frames and RC walls to predict their response under earthquake loading and determine their failure modes.

Global macro models for the beam-column joint and for RC structural walls are developed. The proposed models represent shear and bond slip deformations as well as flexural deformations in the plastic hinge regions. The models are capable of idealising the potential failure mechanism due to crushing of concrete, bond slip or shear with allowance for the simultaneous progress in each mode. The model predictions are compared with available experimental data and good correlation is observed between analytical results and the test measurements.
