论张爱玲小说中叙述者与人物的距离控制

张爱玲小说中的叙述者在时间、情感上与人物保持着距离,这样的距离控制使得她的小说呈现出一种苍凉、冷峻的叙述风格,具有一种穿透人性隐秘的深度和力量。     

定向越野应用于农村中学生中长跑训练的实验研究

多年来,学生对中长跑兴趣低,一直是中长跑训练的难点,也是我国学生心肺功能和耐力素质较差的原因之一。该研究将一种新兴的体育运动项目———定向越野运动引入农村学校中长跑训练中,以期提高学生对中长跑的兴趣,培养自觉锻炼的习惯,使学生的心肺功能和耐力素质得以提高。

Generalized minimum distance estimators of a linear model with correlated errors

R^p of a linear regression model of the type Y = Xθ + ɛ, where X is the design matrix, Y the vector of the response variable and ɛ the random error vector that follows an AR(1) correlation structure. These estimators are asymptotically analyzed, by proving their strong consistency, asymptotic normality and asymptotic efficiency. In a simulation study, a better behaviour of the Mean Squared Error of the proposed estimator with respect to that of the generalized least squares estimators is observed.

An isomorphism check for two-level fractional factorial designs

Two fractional factorial designs are isomorphic if one can be obtained from the other by reordering the treatment combinations, relabelling the factor levels and relabelling the factors. By defining a word-pattern matrix, we are able to create a new isomorphism check which is much faster than existing checks for certain situations. We combine this with a new, extremely fast, sufficient condition for non-isomorphism to avoid checking certain cases. We then create a faster search algorithm by combining the Bingham and Sitter [1999. Minimum aberration fractional factorial split-plot designs. Technometrics 41, 62–70] search algorithm, the isomorphism check algorithm of Clark and Dean [2001. Equivalence of fractional factorial designs. Statist. Sinica 11, 537–547] with our proposed isomorphism check. The algorithm is used to extend the known set of existing non-isomorphic 128-run two-level regular designs with resolution ?4$?4$ to situations with 12, 13, 14, 15 and 16 factors, 256- and 512-run designs with resolution ?5$?5$ and ?17$?17$ factors and 1024-run even designs with resolution ?6$?6$ and ?18$?18$ factors.     

西美尔"距离"的现代性解读

面对工具理性对个体生存的全面控制,以及现代生活的诗性缺乏,西美尔提出"距离"这一概念.在他看来,现代资本主义工业文明导致个性日益沦丧,因此,现代个体及艺术只有远离被工具理性控制的现代生活,才能对异化文明进行抵御,最终实现个体的审美救赎.     

网络媒介与网络文学的后现代性

印刷文学的线性阅读、文本的封闭性、对时空限制的打破以及交流的私人化等特点被认为是产生现代性的重要因素之一,而网络媒介交互性、去中心化等属性体现着以多元性为精神内核的后现代特质。基于文本介质对文本内容有着重要制约的认识,本文认为,网络媒介的媒介属性塑造了网络文学的特质,这种形塑的路径具体表现在三个方面：一是距离感的消失,二是图像增殖,三是拟像、对话与播撒并存等,正是这些因素使网络文学表现出与后现代性相类似的特质。     

The Impact of Perceived Flood Exposure on Flood‐Risk Perception: The Role of Distance

Natural hazards, such as major flood events, are occurring with increasing frequency and inflicting increasing levels of financial damages upon affected communities. The experience of such major flood events has brought about a significant change in attitudes to flood‐risk management, with a shift away from built engineering solutions alone towards a more multifaceted approach. Europe's experience with damaging flood episodes provided the impetus for the introduction of the European Floods Directive, requiring the establishment of flood‐risk management plans at the river‐basin scale. The effectiveness of such plans, focusing on prevention, protection, and preparedness, is dependent on adequate flood awareness and preparedness, and this is related to perception of flood risk. This is an important factor in the design and assessment of flood‐risk management. Whilst there is a modern body of literature exploring flood perception issues, there have been few examples that explore its spatial manifestations. Previous literature has examined perceived and real distance to a hazard source (such as a river, nuclear facility, landfill, or incinerator, etc.), whereas this article advances the literature by including an objectively assessed measure of distance to a perceived flood zone, using a cognitive mapping methodology. The article finds that distance to the perceived flood zone (perceived flood exposure) is a crucial factor in determining flood‐risk perception, both the cognitive and affective components. Furthermore, we find an interesting phenomenon of misperception among respondents. The article concludes by discussing the implications for flood‐risk management.
