Development of Trigger Levels to Assess Catchment Disturbance on Stream Suspended Sediment Loads in the Magela Creek Catchment,Northern Territory,Australia

Trigger levels for fine suspended sediment (FSS) load in streams are required to identify rainfall-runoff events that have significantly elevated FSS loads, compared with expected background loads, as a result of catchment disturbance. Stream FSS load data collected in the mine-impacted Magela Creek catchment in the wet-dry tropics were used to derive water quality management trigger levels for two approaches – a Before-After-Control-Impact Paired difference design (BACIP) and a regression relationship between observed FSS load and corresponding event discharge characteristics. The results indicate that both the BACIP and regression relationship approaches behave similarly, with similar FSS load events elevated above trigger levels. Notwithstanding this, it is recommended that in order to reliably assess the location and magnitude of a catchment disturbance on FSS load, a combination of BACIP and regression relationship approaches must be adopted. In this study, an event with a FSS load above trigger levels associated with both BACIP and the regression relationship fitted for the downstream site is considered to be significantly elevated as a result of a disturbance within the mine-impacted region. While this technique cannot conclusively determine whether the cause of the disturbance is mine-related or natural (such as fire or bank erosion), it is an efficient statistical method of identifying events that warrant further investigation and management action, if required.     

How Political Support Influences Red Tape through Developmental Culture

This study examines the interrelationship between external political support, internal organizational factors, and red tape, using a sample of information managers from state health and human service agencies. The study defines a red tape model and tests the model by structural equation modeling method. The study finds that political support has a direct effect on red tape. The higher the political support, the lower the level of red tape. The study also confirms an indirect effect of political support on red tape, mediated by developmental culture. Indirect effect through goal clarity has the correct sign but is not statistically significant. Practical recommendations are made for the political environment to provide the opportunity for managerial reforms that are often advocated.     

SEM在中国旅游研究中的方法论应用问题

本文使用元分析的研究方法,选取发表在《旅游学刊》、《旅游科学》、《旅游论坛》和《北京第二外国语学院学报》上的42篇关于结构方程模型（SEM）应用的文献进行分析。重点围绕样本容量、测量变量、模型评价以及研究局限等4个方面讨论SEM在中国旅游研究应用中的方法论问题,并在此基础上提出若干改进意见。     

基于归属感及价值感视角的用户参与影响研究——以在线旅游社区为例

近年来关于用户参与的研究大受欢迎,但鲜有研究从用户参与广度和深度出发,基于社区归属感及服务个人价值独特视角深入探讨用户参与对用户忠诚的影响。本文以在线旅游社区为例,以个人价值理论和基本心理需要理论为基础,采用情境问卷法构建了包含用户参与、用户忠诚、社区归属感及服务个人价值的结构方程模型。研究表明：用户参与广度和深度对用户忠诚都有显著正向影响;安宁生活价值、社会融合价值和社区归属感显著中介于用户参与和忠诚的关系,其中社会融合价值中介作用最强,但社会认同价值没有发挥显著中介作用。本文的新发现在丰富学术界对用户参与相关研究的同时,还对在线旅行企业如何提高用户忠诚有较大参考意义。     

水体游憩环境的体验感知测评——以丹东为例

水体游憩环境是一种服务于人们游憩活动,融环境、经济、社会等功能于一体的生态体验景观网络。以辽宁丹东的青山沟镇、大梨树村、大孤山镇(大鹿岛)及长甸镇(河口岛)等四个村镇为例,采用结构方程模型(SEM)验证了水体生态体验景观网络中活动、背景、体验及利益等行动体属性之间的结构关系,为水体游憩环境规划管理模式的构建奠定理论基础。在模型验证过程中,运用SPSS11.0及AMOS6.0软件测试水体景观网络行动体的结构关系模型及相互作用路径系数;拟合度检验表明,该结构方程模型具有较高的可靠性。     

Effect of dimensions of place attachment on residents’ word-of-mouth behavior

The purpose of this study is to examine and compare the effect of residents’ different dimensions of place attachment on their word-of-mouth (WOM) behavior in two cities: Sydney, Australia and Shanghai, China. A six-dimensional construct of place attachment is proposed based upon a detailed literature review: four attitudinal dimensions (place identity, place dependence, affective attachment, social bonding) and two interactional dimensions (place memory, place expectation) are proposed to reflect different aspects of a resident's attachment to a place. To test the dimensionality of place attachment and relationships between constructs, a survey was completed by 691 residents in the two targeted cities (361 from Sydney and 330 from Shanghai), and a structural equation modeling instrument was applied to analyze the data. The findings of the empirical study statistically support the dimensionality of place attachment proposed, and reveal that, in general, interactional dimensions of place attachment have an effect on WOM behavior. The results suggest that WOM behavior of residents of the two cities is influenced by different attitudinal dimensions of place attachment: Shanghai resident's place identity and social bonding predict one-to-one WOM, while Sydney residents’ affective attachment to Sydney influences their one-to-one WOM behavior. This analysis provides insights into residents’ psychology and behavior in different tourism destinations, as well as important inputs for the sustainable development of destination branding and C2C tourism communication in these two cities.     

On children's independent mobility: the interplay of demographic,environmental, and psychosocial factors

In the past 50 years, a marked reduction has occurred in European and North American children's freedom of movement and outdoor play. Using a structural equation model, the present study investigates the interaction between personal, environmental, and psychosocial factors that affect children's independent mobility. The study involved 313 mothers of 8–10-year-old Italian children. The results supported the hypothesized model: the age of the child, the maternal perception of social danger, and positive potentiality of outdoor autonomy were the most influential variables on children's independent mobility, measured as an index. Further, the maternal perceptions mediated the influence of the other demographic, psychosocial, and environmental variables on independent mobility.     

旅游目的地形象结构与游客行为意图——基于潜在消费者的本土化验证研究

旅游目的地形象一般被认为是由认知形象、情感形象和总体形象构成的三维结构,是影响旅游行为的重要因素,但却很少有经验研究证明该结构及形象与旅游行为之间的关系。本研究以江苏周庄旅游形象为例,用结构方程分析（SEM）方法检验形象结构三维度之间的关系,以及目的地形象与游客行为意图的关系。研究发现：①认知形象对情感形象有较强的正向影响（路径系数=0．77）;②情感形象对总体形象有显著正向影响（路径系数=0．26）;③认知形象对总体形象有显著正向影响（路径系数=0．37）;④情感形象和总体形象对游客行为意图有显著正向影响（路径系数分别为0．33、0．14）,而认知形象对游客行为意图的直接影响不明显（路径系数=0．11）,情感形象对认知形象的影响未得到支持。研究证明了目的地形象三成分结构及其在中国文化背景下的适用性,以及情感形象是影响游客行为意图的最主要的形象成分。论文最后指出了本研究的意义、存在问题及对将来研究的建议。
