海明威短篇小说中的叙事视角分析

诺贝尔文学奖获得者海明威是现代叙事学开创的先锋。以海明威多篇短篇小说为例,分析其作品中的不同叙事视角后发现,他的作品通常采用第一人称叙事、第三人称叙事,并频繁、灵活地进行叙事聚焦的切换与转移,给读者身临其境的感觉。同时,叙事视角的灵活运用也留给读者更大的想象空间,使其叙事更具张力。     

A backward procedure for change-point detection with applications to copy number variation detection

Change-point detection regains much attention recently for analyzing array or sequencing data for copy number variation (CNV) detection. In such applications, the true signals are typically very short and buried in the long data sequence, which makes it challenging to identify the variations efficiently and accurately. In this article, we propose a new change-point detection method, a backward procedure, which is not only fast and simple enough to exploit high-dimensional data but also performs very well for detecting short signals. Although motivated by CNV detection, the backward procedure is generally applicable to assorted change-point problems that arise in a variety of scientific applications. It is illustrated by both simulated and real CNV data that the backward detection has clear advantages over other competing methods, especially when the true signal is short.

“五四”小说叙述视角的变革——以1921-1931年的《小说月报》及其他小说作品为例

“五四”时期,中国小说叙述视角发生了全面变革,第一人称限制视角与第三人称限制视角在小说中的出现打破了中国传统小说全知全能的叙述模式,引发了小说叙述视角的变革,促进了中国现代小说的成型与发展。文章以1921—1931年的《小说月报》及其他小说作品为例,对此作了较为全面和深入的回顾与探讨。     

编辑主张与改革前《小说月报》的风格

作为民初重要的文学杂志,改革前的<小说月报>在中国文学由传统向现代的转型中起了十分重要的作用.本文以媒介主体探讨为入口,考察了不同的编辑及其主张对改革前的<小说月报>风格的影响,主要表现为王蕴章和恽铁樵这两位编辑主张对<小说月报>的封面和插图,栏目设置,杂志定位和内容取舍几个方面的影响.它们使改革前的<小说月报>风格也经由了由介于雅俗之间到以雅为主的变化.

短面板约束下固定效应空间动态面板模型的估计与模拟

空间动态面板数据(SDPD)模型中被解释变量初值极易带有内生性,采用一般拟极大似然(QML)方法容易造成参数估计偏误,特别是当样本结构为n大T小的时候。鉴于此,本文在一般QML基础上,通过重塑误差项的方差-协方差矩阵,修正拟似然函数表达式,得到修正QML,进而估计短面板下含空间、时间、误差三类关联项的固定效应SDPD模型,基于数值模拟和实例应用检验一般QML与修正QML的估计效果。数值模拟结果表明：修正QML比一般QML更精确、更稳健,均方误差修正率随样本短面板结构的增大而增大。实例应用不仅重新评估环境规制与技术创新之间的空间效应,回归结果也再次证实从数值模拟中得出的结论。     

自觉为民族代言的歌者——评白涛的《长调与短歌》

作为蒙古族诗人,白涛是一位自觉地为养育他的民族代言的歌者。他不仅投入了饱满的感情,而且是一种理性的认知。他站立于内蒙古草原这片坚实的大地上,他的写作,是有根性的写作。蒙古族历史文化之深厚博大,足以令他敬畏、仰视,因而,狂放的诗人变得温顺、谦虚、虔诚。白涛的诗,颇具朴野之气,保持着原始的淳朴。在寻根问祖中,他获得了归属、认同,找到了回家的感觉,找寻回了自己的精神原乡。粗线条,大轮廓,写意笔法,绝不谨毛失貌。白涛的文化焦虑是显在的,来自不同方向的力,相排斥,相抗拒,化而为诗,形成作品内在的思想张力。     

Is Video-Game Playing a Risk Factor for Pathological Gambling in Australian Adolescents?

Very little research has been conducted to examine the relationship between video-game playing and gambling in adolescence. In this study, 2,669 adolescents aged 13–17 years were surveyed to obtained details of their involvement in gambling and video-game playing as well as a measure of pathological gambling (the DSM-IV-J). The results showed that, the frequency of video game playing was significantly related to pathological gambling, but that the effect size was very small and largely accounted for by the greater popularity of both activities amongst boys. There was some evidence for stronger associations between technologically similar activities, namely arcade video games and an interest in gaming machines, but other factors discussed in the paper may also account for this association. In summary, the findings suggested that playing video-games is unlikely to be a significant risk factor for pathological gambling during adolescence.

Inflation in Transition Economies: An Empirical Analysis

The present research works with yearly data on backward looking measures of inflation i.e. GDP deflator series for Bulgaria, Czech Republic, Estonia, Hungary, Kazakhstan, Kyrgyzstan, Latvia, Lithuania, and Slovakia. Because of the data limitations in the transition economies annual series are converted to smooth quarterly series before they are employed for inflation prognosis using state space models. The results show statistically significant evidence of time-varying volatility in Bulgaria, Czech Republic, Estonia, Hungary, Kazakhstan, Kyrgyzstan, Latvia, Lithuania, and Slovakia using critical values obtained from χ₃² distributions. The results also show that the non-normality hypothesis cannot be rejected in all the series using critical values due McCulloch (J Bus Econ Stat 15:74–81, 1997). The efficiently estimated inflation forecast range between 0.925 for Bulgaria to 99.106 for Latvia. The estimated value of the characteristic exponent α of 2.000 for Hungary, and for the other countries having α equal to 1.999 shows tendency toward normal behavior in exception of Bulgaria, where α equals 1.861.
