[[alternative]]On the Evolution of ”Liu Quan Jin Gua” in Traditional Chinese Opera
No full text[[abstract]]「劉全進瓜」故事出自《西遊記》第十一回，敘述唐太宗遊地府時，曾答應要給十殿閻羅奉送南瓜。劉全因和妻子吵架，導致其妻李翠蓮自殺，劉全為此捨了性命，願以死進瓜。到了陰間，十殿閻羅明白原委，查看生死簿，發現他夫妻們都有登仙之壽，於是讓劉全還陽，李翠蓮還魂，附身於剛去世的唐御妹李玉英之身，夫妻二人歡歡喜喜還鄉。故事最早見於元代楊顯之的雜劇《劉泉進瓜》，《錄鬼簿》、《太和正音譜》、《元曲選目》、《今樂考證》、《曲錄》均著錄此劇簡名，但今未見傳本。劉全進瓜以其內在的故事張力，在後代戲曲中仍然傳唱不衰，並脫離《西遊記》，以單線發展的形式形成獨立的傳播體系。而在傳播過程中，也被賦予種種內涵，呈現出不同的故事面貌，表現出鮮明的題材選擇傾向。本文即思加以規整，試圖理出此故事演變的軌跡，並看出各種戲曲作品主題思想的差異。[[abstract]]Story of ”Liu Quan Jin Gua” is from the eleventh round of Journey to the West. When Tang Taizong visited the hell, he promised to give pumpkins to Yamaraj. Liu Quan quarreled with his wife, Li Cuilian, and caused her to commit suicide. Liu Quan gave up his life for this and would like to dedicate melons. The story first appeared in the Yuan dynasty. With its inherent story tension, it is still handed down in the future. Separating from Journey to the West, it became an independent communication system by a single line development form. In the process of communication, it was also endowed with various connotations and showed different story appearances and clear tendency to choose themes. In this paper, I would like to regularize and figure out the trajectory of the evolution of this story. In addition, to clarify the differences of main points among the works

Reactive school closure weakens the network of social interactions and reduces the spread of influenza
No full textSchool-closure policies are considered one of the most promising nonpharmaceutical interventions for mitigating seasonal and pandemic influenza. However, their effectiveness is still debated, primarily due to the lack of empirical evidence about the behavior of the population during the implementation of the policy. Over the course of the 2015 to 2016 influenza season in Russia, we performed a diary-based contact survey to estimate the patterns of social interactions before and during the implementation of reactive school-closure strategies. We develop an innovative hybrid survey-modeling framework to estimate the time-varying network of human social interactions. By integrating this network with an infection transmission model, we reduce the uncertainty surrounding the impact of school-closure policies in mitigating the spread of influenza. When the school-closure policy is in place, we measure a significant reduction in the number of contacts made by students (14.2 vs. 6.5 contacts per day) and workers (11.2 vs. 8.7 contacts per day). This reduction is not offset by the measured increase in the number of contacts between students and nonhousehold relatives. Model simulations suggest that gradual reactive school-closure policies based on monitoring student absenteeism rates are capable of mitigating influenza spread. We estimate that without the implemented reactive strategies the attack rate of the 2015 to 2016 influenza season would have been 33% larger. Our study sheds light on the social mixing patterns of the population during the implementation of reactive school closures and provides key instruments for future cost-effectiveness analyses of school-closure policies
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Case Study of Heat Transfer during Artificial Ground Freezing with Groundwater Flow
No full textFor the artificial ground freezing (AGF) projects in highly permeable formations, the effect of groundwater flow cannot be neglected. Based on the heat transfer and seepage theory in porous media with the finite element method, a fully coupled numerical model was established to simulate the changes of temperature field and groundwater flow field. Firstly, based on the classic analytical solution for the frozen temperature field, the model’s ability to solve phase change problems has been validated. In order to analyze the influences of different parameters on the closure time of the freezing wall, we performed the sensitivity analysis for three parameters of this numerical model. The analysis showed that, besides the head difference, the thermal conductivity of soil grain and pipe spacing are also the key factors that control the closure time of the frozen wall. Finally, a strengthening project of a metro tunnel with AGF method in South China was chosen as a field example. With the finite element software COMSOL Multiphysics® (Stockholm, Sweden), a three-dimensional (3D) numerical model was set up to simulate the change of frozen temperature field and groundwater flow field in the project area as well as the freezing process within 50 days. The simulation results show that the freezing wall appears in an asymmetrical shape with horizontal groundwater flow normal to the axial of the tunnel. Along the groundwater flow direction, freezing wall forms slowly and on the upstream side the thickness of the frozen wall is thinner than that on the downstream side. The actual pipe spacing has an important influence on the temperature field and closure time of the frozen wall. The larger the actual pipe spacing is, the slower the closing process will be. Besides this, the calculation for the average temperature of freezing body (not yet in the form of a wall) shows that the average temperature change of the freezing body coincides with that of the main frozen pipes with the same trend
