利用频变地震反射系数识别含气储层

地震波在孔隙介质中传播的渐进方程可用于在地震频带内计算法向入射反射系数,这个频变的反射系数可用一个无量纲的参数ε 来表示,ε 可表示为储层流动性参数（即粘滞性的倒数）、流体密度和信号频率的乘积。利用该表达式,对中国新场气田的实际数据进行了计算,新场气田的储层大多为超致密的砂岩并且渗透率很低。在计算结果上观测到了砂岩储层内过渡区的气水界面上反射系数在地震频带内随频率变化的现象。利用该研究结果指导了地震反演并提取了相应的地震属性,这些属性被首先用于进行的流体（气或水）辨别,最后,在此基础上进行了含气和含水储层的识别。     

The impact of international experience on cultural intelligence: an application of contact theory in a structured short-term programme

The objective of this study is to examine the impact of a short-term international experience, which is designed to address the conditions outlined in Allport’s (Allport, G.W. 1954. The Nature of Prejudice. New York: Perseus Book Group) contact hypothesis, on each of the four factors which make up cultural intelligence (CQ). A sample of 135 university students was broken up into test and control groups. The results for the test group suggest that the short-term experience ranging from 7 to 12 days within a structured study abroad service programme, including modest pre-trip preparation, found a significant increase in each of the four factors of CQ. At the same time, there was no significant change in the control group. Implications for human research development research and practice as well as limitations and suggested areas for future research are discussed.     

Dynamic network analysis of contact diaries

Analyzing two-mode networks linking actors to events they attend may help to uncover the structure and evolution of social networks. This classic social network insight is particularly valuable in the analysis of data extracted from contact diaries where contact events produce — and at the same time are the product of relations among participants. Contact events may comprise any number of actors meeting at a specific point in time. In this paper we recall the correspondence between two-mode actor–event networks and hypergraphs, and propose relational hyperevent models (RHEM) as a general modeling framework for networks of time-stamped multi-actor events in which the diarist (“ego”) simultaneously meets several of her alters. RHEM can estimate event intensities associated with each possible subset of actors that may jointly participate in events, and test network effects that may be of theoretical or empirical interest. Examples of such effects include preferential attachment, prior shared activity (familiarity), closure, and covariate effects explaining the propensity of actors to co-attend events. Statistical tests of these effects can uncover processes that govern the formation and evolution of informal groups among the diarist’s alters. We illustrate the empirical value of RHEM using data comprising almost 2000 meeting events of former British Prime Minister Margaret Thatcher with her cabinet ministers, transcribed from contact diaries covering her first term in office (1979–1983).     

礼仪的交织——以抄本清初中国天主教葬礼仪式指南为例

对明末清初中西文化交流的研究,主要集中于思想与科学交流,而较少关注礼仪.但是,礼仪是中国文化很重要的一个特色.作者以清初的丧葬礼仪为例,从社会学及人类学的角度分析中国儒家与欧洲天主教礼仪的互动与交织.在17世纪中期,中国天主教葬礼已经变得较为巩固,然而传教十和中国信徒仍然在为葬礼的具体形式寻求共识.文献显示,广州事件过后,传教士和中国信徒移植天主教礼仪的方法发生了变化,由原来的简单调整,改为进行一系列的重组,因为中国的文化传统是如此之强势.     

语言接触与撒拉语的变化

本文根据撒拉语与汉语之间的语言接触情况,分析了撒拉语在词汇、语音、语法等方面所发生的朝着汉语方向发展的趋势,并指出来自于汉语方面的持续而强烈的影响是撒拉语濒危的主要因素。     

教育科研成果推广应用中的交往圈探析

教育科研成果的推广不仅能促使潜在生产力的转化,更能形成人际交往圈,促进教育与科研的良性互动.本文探讨了教育科研成果推广过程中交往圈的形成及特点、运行机制、交往方式,以期探明教育科研成果推广过程中的交往与日常人际交往的区别,促进教育科研成果的推广与应用.     

论马克思主义人学视野中的交往问题

交往是马克思主义人学的一个重要范畴。深入研究马克思主义人学交往理论 ,具有重大的理论意义和实践价值。本文从交往与人的主体性、交往与人的个性、交往与人的社会性、交往与人的发展、交往与人的解放五个方面深入揭示了交往范畴的人学蕴涵     

从"通事"到"翻译官"--论近代中外语言接触史上的主、被动角色的转移

在对明清以来中外语言接触的研究中,"通事"作为这一过程的重要交流媒介不可忽视.这些在16世纪至19世纪初担当广东沿海中外贸易和交涉事务的翻译人员有的来自民间,有的为官方指派.他们与后来同文馆、广方言馆科班毕业的"翻译官"不只是表面上称呼的不同,更反映出其时位居高官的朝廷大员是在一个十分"被动"的状态下开始学洋语的:由藐视"番人"、"鬼话"到被迫学洋语,识洋务,从对"通事"的不信任到对"翻译官"的竭力培养.同一个角色所处的地位经历的这种"自下到上"的巨大转变,其背后的社会动因值得作一研究.     

Perinatal factors related to post-traumatic stress disorder symptoms 1–5 years following birth

BackgroundThe relationship between perinatal variables and post-traumatic stress disorder (PTSD) symptoms was studied. However, the role of some variables in PTSD symptoms is unclear.AimDetermine the prevalence of PTSD symptoms after 1 year postpartum and their relationship with perinatal variables.MethodsA cross-sectional study with 1531 puerperal women in Spain. Data were collected on socio-demographic variables, perinatal variables (maternal characteristics, procedures during labour and birth, birth outcomes and time since birth) and the newborn. An online questionnaire was used, which included the Perinatal Post-traumatic Stress Questionnaire (PPQ). Crude and adjusted odds ratios (OR) were calculated using binary logistic regression.Findings7.2% (110) of the women were identified as being at risk for probable PTSD symptoms. Protective factors were having a birth plan respected (aOR 0.44; 95%CI 0.19−0.99), use of epidural analgesia (aOR 0.44; 95%CI 0.24−0.80) and experiencing skin-to-skin contact (aOR 0.33; 95%CI 0.20−0.55). Risk factors were instrumental birth (aOR 3.32; 95%CI1.73−3.39), caesarean section (aOR 4.80; 95%CI 2.51–9.15), receiving fundal pressure (aOR 1.72; 95%CI 1.08–2.74) and suffering a third/fourth degree perineal tear (aOR 2.73; 95%CI 1.27–5.86). The area under the model’s ROC curve was 0.82 (95%CI 0.79−0.83).ConclusionsWomen who experience a normal birth, are psychologically prepared for birth (for example, through use of a birth plan), experience skin-to-skin contact with their newborn, and had a sense of physical control through the use of epidural analgesia, are less likely to experience childbirth as traumatic.
