场域视角下的民初第一小说季刊《小说大观》

1915年,中国第一小说季刊《小说大观》创刊。作为面向市场的通俗文学刊物,《小说大观》不仅是集结作家、编辑、出版商这些文学场中主要行动者的重要活动平台,也是交织着政治资本、经济资本和文化资本争斗的场域,其结果进而影响着刊物底色的形成。     

Narrative reasoning and coherent alignment in field placement

ABSTRACT

In social work, field placement is considered an essential component to prepare students for professional practice. A significant degree of disjunction between academic and practical learning also is asserted. The present study aims to explore how students develop their professional competence in field placement and relate their learning outcomes across the university setting and the field. Data from students’ learning contracts and placement reports and a focus-group interview are analysed. Concrete practical experiences and the complexity of problems in specific contexts seem to provide inputs on the development of students’ knowledge, skills and personal competence outside the university setting. Although the students were asked to account for these three dimensions separately, the findings demonstrate their ability to connect and integrate them in the narrative reasoning that characterises students’ reflections on their learning from placement. Moreover, our findings show that all three dimensions are developed in both the university setting and in field placement. Preparing students properly for placement training and calling for specific reports on learning outcomes allow access to meaningful connections that are created and developed between the university setting and field placement.     

理工科大学生课堂环境下二语词汇能力发展研究

通过以接受性词汇量、产出性词汇量、词汇深度知识为词汇能力的三个维度，调查了理工科大学生在课堂环境下经过两年的英语学习词汇能力的发展过程。研究结果发现，经过第一学年的课堂英语学习，他们的接受性词汇量和词汇深度知识都得到了显著发展，而产出性词汇量却没有得到发展。而在经过第二学年的学习后，词汇能力的三个维度都得到了显著发展。接受性词汇量、产出性词汇量与词汇深度知识在不同的学习阶段均有显著相关。     

中国的“电子政府”研究:一个新兴学术领域之思

电子政府既是中国政府实践的一个新现象,也是中国学术研究的一个新领域。作为政府实践的新现象,它需要技术、社会公众与学术的3种支持力量。作为学术研究的新领域,它既意味着学者、话语与理论的三方出场;也意味着从线性、平面与立体的3个维度展开;同时,还可以从过去、当下与未来的3个层面进行理论反思。     

大时代与知识分子的心底波澜

《废都》的出版到《废都》的再版，其本身的历史语境和潜在的文本内涵都是一个令人深思的话题。通过对这一现象的梳理和审视，还原历史影城中的文化冲突之景，挖掘出社会转型期知识分子潜隐心灵的伪狂欢和自我确证的深层次吁求。     

深水基础钢板桩围堰最小入土深度分析

以沪杭高铁横潦泾特大桥河道中央主墩深水基础钢板桩围堰为例，分别采用空间有限元法、平面有限元法和等值梁法，计算钢板桩的最小入土深度。计算结果表明:等值梁法可用于桥梁深水基础钢板桩围堰的最小入土深度计算，且计算结果偏于安全；空间有限元法、平面有限元法和等值梁法所计算的钢板桩最小入土深度依次增大，但变化幅度不大；采用等值梁法计算钢板桩最小入土深度时，对于封底混凝土以下的多层土，可以采取等效土层的方法计算作用在钢板桩上的主动和被动土压力，从而简化土压力的计算。     

薄壁空心高墩温度效应仿真分析

日照温度荷载作用下，混凝土薄壁空心高墩的应力和变形，是造成墩身工程事故的主要因素之一。以晋济高速公路仙神河大桥150.07 m高的八边形薄壁空心高墩为研究对象，在ANSYS平台上进行二次开发，编制了薄壁空心高墩结构温度场和温差效应分析的专用程序，并给出实例验证了二次开发成果的准确性。同时利用二次开发成果，对八边形薄壁空心高墩在日照温差荷载作用下的温差效应进行了仿真分析。计算结果表明:日照引起的薄壁空心高墩结构的温差应力和变形较大，不容忽视。

Euler characteristic heuristic for approximating the distribution of the largest eigenvalue of an orthogonally invariant random matrix

The Euler characteristic heuristic has been proposed as a method for approximating the upper tail probability of the maximum of a random field with smooth sample path. When the random field is Gaussian, this method is proved to be valid in the sense that the relative approximation error is exponentially smaller. However, very little is known about the validity of the method when the random field is non-Gaussian. In this paper, as a milestone to developing the general theory about the validity of the Euler characteristic heuristic, we examine the Euler characteristic heuristic for approximating the distribution of the largest eigenvalue of an orthogonally invariant non-Gaussian random matrix. In this particular example, if the probability density function of the random matrix converges to zero sufficiently fast at the boundary of its support, the approximation error of the Euler characteristic heuristic is proved to be small and the approximation is valid. Moreover, for several standard orthogonally invariant random matrices, the approximation formula for the distribution of the largest eigenvalue and its asymptotic error are obtained explicitly. Our formulas are practical enough for the purpose of numerical calculations.
