Network analysis of tourist flows: a cross-provincial boundary perspective

In contrast to the extensive research regarding tourist flows on the international, intranational, interregional, intercity, intracity and tourism-spot scales, little attention has been paid to the cross-provincial boundary perspective. In view of the fact that China's provincial administrative boundaries have a long history and a profound influence on the society, culture and economy of neighboring provinces, this study focuses on tourist-flow networks in China that cross ‘provincial’ boundaries. Tourist-flow data from a questionnaire survey and travel-agency-recommended routes were acquired, and the social network analysis method and boundary effect analysis were adopted for the first time to study the cross-boundary tourist flows. Lugu Lake in China was selected for the case study. The spatial distribution and impact factors of cross-boundary tourist flows are discussed, and a scientific basis for future collaborations among cross-boundary tourism destinations is provided. The following conclusions are reached. (1) The spatial structure of cross-boundary tourist-flow networks is complex. There is a core–periphery structure, and each node assumes different roles and functions. (2) Cross-boundary tourist flows are significantly influenced by the boundary-shielding effect, and the properties, direction and extent of the effects are diverse and depend on accessibility, resource endowments, resource heterogeneity and the extent of regional integration. (3) Cross-boundary tourist flows are affected by a boundary-mediating effect, and structural holes play a critical role in the boundary-mediating effect and drive the integration of regional tourism.

Investigating the Periodicities of Step‐Pool Sequences in Alluvial Mountain Streams

Step‐pool mountain streams contain a rhythmic structure that can be characterized by the periodicity, commonly determined using spectral analysis. However, this analysis often requires data series recorded at equal intervals and exhibiting stationary patterns. Previous methods of transforming the original step‐pool sequence into this required format have not been rigorously tested and consequently may generate misleading periodicity results. To this end, we apply both spectral analysis and autoregressive integrated moving average (ARIMA) modeling, a parsimonious stochastic approach to 11 alluvial mountain step‐pool streams for identifying their periodicities. We interpolate the original sequences into those with four different equal‐space intervals, 0.1 m, 0.2 m, 0.3 m, and 0.4 m, and demonstrate that the differencing detrending method is statistically more effective to transform the sequences into stationary ones than the commonly used linear detrending method. Subsequently, we identify periodicities of these sequences using the two approaches and determine the degree of stability for these periodicities for each original step‐pool sequence using R ² values obtained by least squares linear regression between the log‐transformed identified periods and the associated equal‐space intervals. Eight out of 11 step‐pool sequences have relatively stable periodicities (R ² ≥ 0.79) when the spectral analysis approach is used, while those identified using the ARIMA modeling approach are much less stable. Further comparison of periodicities identified using both approaches suggests that periodicities of step‐pool sequences are inherently unstable and hence cannot be appropriately determined based on a single equal‐space interval. A general procedure for identifying the periodicity of a step‐pool sequence using spectral analysis with the differencing detrending method and multiple equal‐space intervals is proposed. The identified periodicities might serve as an independent morphologic index to infer hydraulic processes controlling the formation of the alluvial step‐pools because they are significantly related to spill resistance of the alluvial step‐pools. Investigando las periodicidades de formación de escalones (step‐pools) en corrientes aluviales de montaña Las corrientes en forma de escalones (step‐pools) contienen una estructura rítmica que puede ser caracterizada por su periodicidad, determinada comúnmente usando análisis espectral. Sin embargo, este análisis requiere muchas veces de series de información recogidas a intervalos iguales y que tengan patrones estacionarios establecidos. Métodos precisos para transformar la secuencia original de step‐pools en este formato no han sido rigurosamente probados y consecuentemente pueden generar resultados de periodicidad que pueden ser interpretados erróneamente. Para este fin, los autores utilizan tanto un análisis espectral como un modelo autorregresivo integrado de media móvil (autoregressive integrated moving average ‐ ARIMA) en una aproximación estocástica parsimoniosa (parsimonic stochastic approach) a 11 step‐pools de corrientes de montaña para identificar sus periodicidades. Los autores interpolaron las secuencias originales a dichas corrientes con 4 zonas de igual área con diferentes intervalos: 0.1 m, 0.2 m, 0.3 m., 0.4 m y comprobaron que el método de diferenciación que elimina la tendencia (differencing detrending method) es estadísticamente más efectivo para transformar las secuencias en estacionarias que el comúnmente utilizado método que elimina la tendencia linear. Subsecuentemente, se identificaron periodicidades de secuencias utilizando estas dos aproximaciones y se determinó el grado de estabilidad para estas dos periodicidades para cada secuencia original de los step‐pools usando valores R² obtenidos por una regresión linear mínimo‐cuadrado (Ordinary Least Squares–OLS) entre los periodos identificados vía transformación logarítmica y los intervalos asociados de igual área. 8 de las 11 secuencias de step‐pools analizados tuvieron periodicidades relativamente estables (R2 ≥ 0.79), mientras que aquellas utilizando la aproximación ARIMA resultaron mucho menos estables. Comparación adicionales de las periodicidades identificadas usando ambas aproximaciones sugiere que las periodicidades de las secuencias de step‐pools usando análisis espectral son inherentemente inestables y en consecuencia no pueden ser determinadas apropiadamente basadas en un solo intervalo en zonas de igual área. Se propone así un procedimiento general para establecer la periodicidad de la secuencia de step‐pools usando el análisis espectral junto con el differencing detrending method que elimina la tendencia y múltiples intervalos en zonas de igual área. Las periodicidades identificadas podrían servir como índice morfológico independiente para inferir procesos hidráulicos controlando la formación de step‐pools aluviales, dado que está significativamente relacionado a la resistencia al derrame de dichos step‐pools 阶梯‐深潭山涧包含的韵律结构具有周期性特征,一般通过谱分析的方法探测。然而,这种分析方法通常要求数据序列记录在每个间隔上具有平稳性。由于先前方法对序列的转化没有严格要求平稳性检验,因而可能导致序列结果的误解。为此,本文融合谱分析和移动平均自回归模型（ARIMA）,通过随机简化路径方法对11个冲积山流域阶梯‐深潭山涧序列周期进行判别。主要采用0.1m,0.2m,0.3m,0.4m四种不同等间距对原始序列进行插值,分析表明这个差分校正方法对于序列平稳性的变换比常用线性校正方法在统计上更为有效。因此,对每一原始序列在对数变换的时间和相关等空间间距之间通过最小二乘回归获得R²值,并采取两种方法判别序列周期以确定其稳定度。谱分析方法测试得11个中的8个序列具有相对稳定的周期(R² ≥ 0.79),而采用ARIMA模型进行判别则平稳周期序列数目少得多。通过融合两种方法对序列判别以进一步形成对照,分析表明序列周期存在内部不稳定性,因此不能基于单一的空间间隔来确定周期。从而,本文提出采用谱分析对序列差分校正方法结合多空间间隔的一般方法对序列周期性进行识别。该周期识别方法可作为一个独立形态指数对控制冲积阶梯‐深潭形成的水力过程作出推断,因为该指数与冲积阶梯‐深潭稳定性的表达具有显著相关性。     

乾隆十一年福安教案述論——以巴黎外方傳教會中文檔案爲中心展開

福安是明清時期中國天主教最爲發達的地區之一,也是教案頻發之地,而清乾隆十一年爆發的福安教案在中國傳教史上極具影響力。它不僅是中國天主教傳教史上第一次流血的教案,而且還促成了嘉道時期清政府在立法中訂立了對西洋人治罪的律令專條。這對中國天主教的正常傳播與發展産生了根本性的影響。以往對此事件研究者雖多,但由於資料、檔案屢屢披露發現,故以往成果多有偏頗。本文竭力綜合各類中西原始檔案,深挖全案的過程、原因及影響,以圖超邁。

Seismic Response of Rolling Isolation Systems with Concave Friction Distribution

This article attempted to improve the isolation performance of a rolling isolation system by assuming that the rolling friction force gradually and linearly increased with the relative displacement between the isolator and the ground. After the rolling isolation system under different ground motions was calculated by a numerical analysis method, it obtained more regular results than that of other uneven friction distributions. Results shows that the considered concavely distributed friction force can not only dissipate the earthquake energy, but also change the structural natural period. These functions improve the seismic isolation efficiency of the structural relative displacement in comparison with the general uniform distribution of rolling friction coefficient.     

杭州南宋遗址出土官窑类瓷片的科技研究

本文采用荧光能谱仪(EDXRF)测试了杭州卷烟厂、严官巷、吴庄和太庙四处南宋遗址出土的官窑类瓷片的胎釉元素组成;并根据胎体元素分类情况,制备了光学薄片,运用偏光显微镜对部分官窑瓷片的胎体进行了岩相分析。在此基础上,本文对杭州这些遗址出土官窑类瓷片的窑口问题进行了初步讨论。结果表明四处南宋遗址出土的56块官窑类瓷片当中,有48块样品可能为杭州两窑烧造,而有8块样品的胎体元素组成更接近龙泉黑胎青瓷,结合判别分析和岩相分析结果,这八块样品为龙泉窑烧造的可能性更大,但具体窑口尚需进一步研究。
