空间视角下旅游休闲场所的主客关系 ——以广州白天鹅宾馆大堂为例     

古恒宇  陶伟 《热带地理》2021,41(1):82-92

利用空间句法理论对广州市白天鹅宾馆大堂的空间组构规律进行分析,并结合深度访谈、参与式观察等质性分析方法,探究空间因素在主客交往过程中的作用机制。结果发现：1）酒店大堂呈现“视觉整合统一,空间分割互补”的空间构型特征,该特征与游客需求相适应。2）大堂中的主客关系表征出接触时间短、受限于特定时空间、地位不平衡等特点,游客在主客关系中的地位高于酒店员工,酒店的盈利性是塑造主客关系不平衡性的主要原因。3）空间对不平衡主客关系的塑造和维持具有重要意义：大堂空间“迎合”了各类旅游休闲者的需求,促进其旅游休闲体验的提升,同时“规训”了酒店员工的行为;空间对部分酒店员工产生了正向的“外溢”作用;空间是展现酒店服务水平的“门面”和“舞台”,酒店管理者试图通过大堂的空间设计维持不平衡的主客关系。4）酒店管理者及员工有意图地为游客营造“家”的感受,提升其满意度及出行体验。“家”的建构与游客现代性背景下的情感有关,在特定的空间构型下可外化为舒适性、便利性等诸多体验,并作用于其消费等行为。  相似文献   

Nonlinear coherent four‐wave interaction in space plasma     

A.V. Volosevich  C.‐V. Meister 《Astronomische Nachrichten》2000,321(4):263-272

According to a widespread point of view, intensive electrostatic structures in the E‐region of the auroral ionosphere can be a consequence of the excitation of the modified two‐stream or Farley‐Buneman (FB) plasma turbulence. But in spite of the successes of the theoretical and experimental research of the auroral radar scattering, it is impossible to explain the existence of auroral echoes with large aspect angles (> 2 deg.), the wave propagation perpendicular to the electron drift velocity and wave scales less than 1 m. In this paper the coherent nonlinear interactions of three and four electrostatic FB‐waves are considered analytically and numerically. The evolution of the nonlinear waves is described by a system of magnetohydrodynamic equations. 1) It is shown that the interaction of three and four coherent waves is the main physical mechanism which leads to the saturation of the FB‐instability. 2) If no dissipative and dispersive effects occur, an explosive instability may be excited. 3) The main result of the interaction of coherent waves is the generation of nonlinear waves and nonlinear structures when the waves are damped linearly and propagate perpendicular to the electron drift velocity. This region corresponds to large aspect angles of the small‐scale waves. 4) Further, the wave interaction causes a nonlinear stabilization of the growth of the high‐frequency waves and a formation of local density structures of the charged particles. The results of the numerical models allow to analyse the possibility of scenarios of the two‐stream plasma instability in the collisional auroral E‐region.  相似文献   

Current-driven plasma turbulence in a magnetic flux tube     

V.E. Zakharov  C.-V. Meister 《Astronomische Nachrichten》1999,320(6):425-436

The behaviour of a multi-component anisotropic plasma in a magnetic flux tube is studied in the presence of current-driven electrostatic ion-cyclotron turbulence. The plasma transport is considered in both parallel and perpendicular directions with respect to the given tube. As one of the sources of the parallel electric field, the anomalous resistivityof the plasma caused by the turbulence is taken into account. The acceleration and heating processes of the plasma are simulated numerically. It is found that at the upper boundary of the nightside auroral ionosphere, the resonant wave-particle interactions are most effective in the case of upward field-aligned currents with densities of a few 10^—6 A/m². The occurring anomalous resistivity maycause differences of the electric potential along the magnetic field lines of some kV. Further it is shown that the thickness of the magnetic flux tube and the intensity of the convection strongly influence the turbulent plasma heating.  相似文献
