生活风格对游客旅游照片分享行为的影响——以西安大唐芙蓉园为例

生活美学时代,旅游与生活交织在一起,旅游者的需求和行为正在从匆忙的景观凝视向多元的生活方式转变。生活风格是一种整体偏好,塑造个体的生活模式和行为习惯。旅游活动呈现强烈的情感消费特征。采用结构方程建模方法（SEM）,以情绪评价理论为基础,选择西安大唐芙蓉园为案例地,探讨生活风格通过情感中介变量对游客旅游照片分享行为的影响机制。结果显示：1）生活风格对游客旅游照片分享行为具有不显著的负向影响,在旅游仪式感和自我认同感的中介作用下,对游客旅游照片分享行为产生重要间接影响。2）生活风格对游客的旅游仪式感、真实性感知和自我认同感均具有显著正向影响。3）旅游仪式感、自我认同感对游客旅游照片分享行为有显著正向影响,在生活风格和游客旅游照片分享行为之间发挥中介作用。4）真实性感知对游客旅游照片分享行为具有不显著正向影响,未在生活风格和游客旅游照片分享行为之间发挥中介作用。     

The PWaves From the Amchitka Island Explosions

Summary. There is evidence that the equivalent seismic sources of the Amchitka Island explosions — Longshot, Milrow and Cannikin — depart significantly from the simple model of a point compressional-source in a layered elastic-medium. Consequently modelling the observed seismograms using standard source-models may not be the most efficient method of determining source properties. Here an alternative to modelling is used to obtain information on the seismic sources due to the explosions. Broad-band (BB) estimates of the P signals are obtained from the short-period (SP) seismograms, corrected for attenuation, and interpreted in terms of P, pP and radiation from secondary sources. the main conclusions are:
(i) BB estimates of the radiated displacement from the explosions can be obtained with only a small reduction in the signal-to-noise ratio seen on SP seismograms;
(ii) observations of differences in pulse amplitudes and spectra are not necessarily due to differences in anelastic attenuation;
(iii) P and pP at a given station may differ in shape so that notches in the signal spectrum may not be related to source depth;
(iv) there is evidence of arrivals that others have identified as due to slap-down but which could be interpreted as an overshoot to pP;
(v) direct interpretation of the estimated ground displacement is a better procedure for determining the seismic source properties of explosions than modelling SP seismograms using idealised models as a starting point.
