历史街区顾客地方依恋与购物满意度的关系——以苏州观前街为例     

钱树伟  苏勤  郑焕友 《地理科学进展》2010,29(3):355-362

基于“地方依恋”与“美国顾客满意度指数(ASCI)模型”基本理论,通过构建顾客地方依恋与购物满意度之间的结构关系模型,采用通径分析、相关分析及验证性因子分析等研究方法,探讨了苏州观前街历史街区型购物场所顾客地方依恋对购物满意度的影响关系,结果表明：①地方依恋对顾客购物满意度、购物抱怨及购物忠诚度均具有不同程度的影响效应;②地方依恋对顾客购物满意度具有最为显著的正向影响、对购物抱怨的直接负向影响显著、通过顾客购物满意度对购物抱怨具有间接的负向影响,但并不显著;③地方依恋对顾客购物忠诚度的直接影响及以购物满意度为中介变量的间接影响均为显著。最后提出了增进观前街与顾客之间人地情感联结关系,以提高顾客游憩及休闲购物满意度的主要途径。  相似文献

田传远  夏珮伦  张嘉荣  于瑞海  郑小东  顾忠旗  黄继 《海洋科学》2020,44(6):122-130

本实验开展了疣荔枝螺（Thais clavigera Kuster）室内全人工繁育技术研究；具体包括亲螺人工促熟蓄养、卵囊采集、孵化、幼虫培育、变态和采苗等技术研究，同时，还开展了后期面盘幼虫对不同附着基的喜好选择性实验，以及不同饵料和光照对幼虫附着的影响研究。研究表明：雌螺分批产卵，单个雌螺平均每次产出受精卵为61 750粒；在水温27~29℃时，面盘幼虫经过20 d左右的生长发育，壳长达到约600 μm，此时开始附着变态，由浮游生活转变为底栖生活；附着后10 d左右变态为稚螺。后期面盘幼虫对附着基的选择性实验表明，固着牡蛎苗的栉孔扇贝壳和附有底栖硅藻的波纹板，是稚螺理想的附着基。不同饵料和光照对幼虫附着影响实验结果表明：在附着变态期间，自然光照有利于幼虫附着变态；同时，连续投喂糠虾肉糜可显著提高幼虫变态率和稚螺成活率。本研究结果为今后疣荔枝螺产业化繁育提供了重要的理论和技术支持。  相似文献

Neurophysiological control of swimming behaviour,attachment and metamorphosis in black-footed abalone (Haliotis iris) larvae     

AC Alfaro  T Young  K Bowden 《新西兰海洋与淡水研究杂志》2014,48(3):314-334

Experiments were conducted to test the effect of a range of chemicals on larval responses in swimming behaviour, attachment and metamorphosis of the black-footed abalone (Haliotis iris). The effect of antibiotics on larval survival was first tested within negative (filtered seawater) and positive (GABA at 10^?5, 10^?4 and 10^?3 mol L^?1) control assays over 3 days. This experiment corroborated the effectiveness of using antibiotics to improve survival of larvae without obvious synergistic interactions with the GABA inducer or confounding effects of potential bacterial interactions. Chemical treatments (acetylcholine, potassium chloride, dopamine and glutamine) were then tested at various concentrations for their ability to modulate swimming behaviour and induce larval attachment and metamorphosis over 14 days. Generally, larval state shifted from swimming to attached, and from attached to metamorphosed, in the control and treatments over time. However, the peak percentage of attached and metamorphosed larvae varied in time among chemicals and concentrations. While overall percent metamorphosis was minimally enhanced after 14 days of exposure to some chemical treatments at certain concentrations, all treatments displayed significant capacities to down-regulate larval swimming and induce early attachment and metamorphosis. Mortality was recorded throughout the duration of the experiment, and was generally low (<20%) across controls and most treatments for exposures of less than 12 days. Interpretations of specific results from this study are used to elucidate neurophysiological control of larval activities for this abalone species. Comparisons with other marine invertebrates highlight the specificities of chemical cues and endogenous regulatory mechanisms across relatively closely related taxa.  相似文献   

A Photo-elicitation Approach to Exploring the Place Meanings Ascribed by Campers to the Ningaloo Coastline,North-western Australia     

Joanna Tonge  Susan A. Moore  Maria M. Ryan  Lynnath E. Beckley 《The Australian geographer》2013,44(2):143-160

Although there have been numerous studies of the meanings ascribed to terrestrial places, their applicability or otherwise to coastal and marine places has received limited attention. Through the process of photo-elicitation, the meanings ascribed to a remote coastal camping environment are examined, with the coastline of Ningaloo Marine Park in north-western Australia the focus for this study. Thirty participants were provided with digital cameras and the ascribed place meanings were explored when their photographs were discussed in subsequent in-depth interviews. Key meanings related to the physical environment providing opportunities for escape, participating in multiple marine-based activities, bonding with family and like-minded people, and offering a rewarding experience that makes everybody happy. This emergent meaning of ‘everybody's happy’ progresses the understanding of the affective elements of place, especially those realised by families and groups of friends. The paper traces important implications of this meaning, and provides a paradoxical perspective on isolation evident from the interviews, for managing coast-based recreation.  相似文献   

基于ITCM的旅游者地方依恋价值评估——以九寨沟风景区为例   总被引：2，自引：0，他引：2  

肖潇  张捷  卢俊宇  尹立杰 《地理研究》2013,32(3):570-579

旅行费用法(TCM)已被广泛运用于旅游地的游憩价值评估中。地方依恋作为“人—地”关系的重要组成部分,其经济价值的评估对旅游地的发展有重要意义。本文选取九寨沟风景区为案例地,按不同交通工具分类测量了旅游者的旅行费用并构建了旅行费用与地方依恋的结构方程模型。研究发现,地方依恋的两个维度:地方依赖和地方认同之间存在显著的正向影响。地方依赖和地方认同从不同程度上促进了九寨沟游客旅游需求的增长。通过ITCM计算消费者剩余,得出地方依恋对九寨沟总体游憩价值的贡献率为5.6%,直观反映了地方依恋对景区的经济推动作用,对地方理论在经济管理领域的运用及旅游地地方性的营造和整体形象的提升有重要的指导意义。  相似文献   

Effect of charging of aerosols in the lower atmosphere of Mars during the dust storm of 2001     

Marykutty Michael 《Planetary and Space Science》2008,56(13):1696-1702

Aerosols are very important in the Martian climate system. Aerosols get charged by the attachment of ions in the atmosphere. Charging of aerosols reduces the conductivity of the atmosphere as the very mobile ions are lost during the ion-aerosol attachment. During a dust storm the dust opacity increases and more ion-aerosol attachment process occurs and consequently conductivity reduces further. It was found that with the background aerosols (dust opacity ∼0.2), the conductivity close to the surface of Mars was reduced by a factor of 5, but during the dust storm (opacity ∼5) of 2001 the conductivity decreased by about 2 orders of magnitude.  相似文献   

岭南传统民俗节庆重构对居民地方依恋的影响——以广州珠村乞巧节为例     

陶 伟陈慧灵  蔡水清 《地理学报》2014,69(4):553-565

民俗节庆对居民地方依恋的影响研究为认识居民和地方之间的关系,提供了一个新的视角。国内关于地方依恋的探讨尚处于萌芽阶段,应用研究主要以旅游地和旅游者为对象。乞巧节是岭南传统民俗节庆的重要组成部分,在沉寂淡化半个世纪之后又重新兴起,节日的内容形式功能已被重构。本文从新文化地理学的视角,以珠村居民为研究对象,通过问卷调查、深度访谈并结合因子分析的方法来探究民俗节庆的重构与居民地方依恋之间的关系。结果表明：① 乞巧节对珠村世居居民、新移居居民、租房于珠村的居民这三种不同身份居民心理形成过程中的情感、认知和意向都产生了重要作用,乞巧节使居民们更好地融合到了珠村社区。② 重构后的乞巧节在改善原住居民精神生活、优化珠村村落风貌、提升珠村族群的凝聚力、增强文化自豪感、保护乞巧文化及推动珠村的发展等方面产生了重要的影响和作用。③ 重构后的传统民俗节庆生产了新的文化记忆,其如何被居民内化吸收、如何被整合进原生态的乞巧文化中,都有待探索。本研究对丰富地方依恋在微观空间层面的理论和实证研究有着重要意义。  相似文献   

Importance of reversible attachment in predicting E. coli transport in saturated aquifers from column experiments     

《Advances in water resources》2014

Drinking water wells indiscriminatingly placed adjacent to fecal contaminated surface water represents a significant but difficult to quantify health risk. Here we seek to understand mechanisms that limit the contamination extent by scaling up bacterial transport results from the laboratory to the field in a well constrained setting. Three pulses of Escherichia coli originating during the early monsoon from a freshly excavated pond receiving latrine effluent in Bangladesh were monitored in 6 wells and modeled with a two-dimensional (2-D) flow and transport model conditioned with measured hydraulic heads. The modeling was performed assuming three different modes of interaction of E. coli with aquifer sands: (1) irreversible attachment only (best-fit k_i = 7.6 day⁻¹); (2) reversible attachment only (k_a = 10.5 and k_d = 0.2 day⁻¹); and (3) a combination of reversible and irreversible modes of attachment (k_a = 60, k_d = 7.6, k_i = 5.2 day⁻¹). Only the third approach adequately reproduced the observed temporal and spatial distribution of E. coli, including a 4-log₁₀ lateral removal distance of ∼9 m. In saturated column experiments, carried out using aquifer sand from the field site, a combination of reversible and irreversible attachment was also required to reproduce the observed breakthrough curves and E. coli retention profiles within the laboratory columns. Applying the laboratory-measured kinetic parameters to the 2-D calibrated flow model of the field site underestimates the observed 4-log₁₀ lateral removal distance by less than a factor of two. This is promising for predicting field scale transport from laboratory experiments.  相似文献
