论阿英的新文学史料学思想及其前瞻性

作为新文学史料学的开拓者,阿英树立了与时代同步的史料观,并以史家宽广的眼光和标准来观照史料。他较早地认识并阐述了新文学版本的重要性,形成了独辟蹊径、逐渐成熟的选文思想。他不仅以文学性和艺术性来评判文学史料的价值,而且大胆地肯定被作家本人所删弃的作品的史料价值;他不仅阐述了日记、书信的历史参考价值,并且在确认"文坛指掌图"价值的同时,充分认识到史料工作的特殊价值和独立品格,将其与文学创作视为是同等重要的学术事业。研究阿英的新文学史料学思想及其前瞻性,对于正确认识史料工作的地位,激励研究者致力于史料学学科建设和发展,具有重要的促进作用。

基于农民视角的宅基地流转社会效益评价——以张家港市为例

因近几年农村宅基地流转的频繁,特从农民的角度,以目前主要进行的征收模式、出租模式为研究对象,根据阿玛蒂亚·森的可行能力理论建立宅基地流转社会效益评价指标体系,并运用模糊综合评价法评价宅基地流转后产生的社会效益.研究发现：征收模式的社会效益相对较高,出租模式的社会效益相对较低,由此提出进一步完善农村宅基地流转的政策建议.     

Assessment of landscape patterns affecting land surface temperature in different biophysical gradients in Shenzhen, China

The urban heat island (UHI) effect is one of the important ecological effects of urbanization. This study focuses on the different effects of landscape patterns on LST within different land covers. The land cover was measured by surface biophysical components, including vegetation fraction (VF) and impervious surface area (ISA), acquired by a linear spectral mixture model (LSMM). LST was derived from Landsat-5 TM thermal infrared (TIR) data using the generalized single-channel method. Landscape patterns were measured by landscape metrics, including the Shannon diversity index (SHDI), the aggregation index (AI), patch density (PD), and fractal dimension area-weighted mean index (FRAC_AM). Shenzhen, a rapidly urbanizing city in China, was taken as the case study area. Results showed that VF and ISA are more important than spatial patterns in determining LST. However, these effects change in densely covered areas. VF and LST are negatively correlated, with the inflection of the regression curves being 45 %. In areas with VF lower than 45 %, the correlation between LST and VF is monotonically linear. In areas with VF higher than 45 %, landscape patterns can act to decrease LST. The aggregation index (AI) and the largest patch index (LPI) can contribute to decreasing LST significantly. Impervious surfaces contribute to high temperature, and the inflection point of the regression curves is 70 %. In areas with ISA higher than 70 %, a fragmented pattern of impervious surfaces can lower LST. These findings provide insights for planners into how the strategic use of landscape to mitigate UHI effects may vary for different land covers.     

汶川地震灾后社会工作介入模式探讨

社会工作介入汶川地震灾后重建,形成政府主导、社会组织主导、高校主导的三种模式,这三种模式各有优缺点。汶川地震灾后重建,出现重社区公共基础设施建设,轻社会服务、轻社区文化与精神建设的现象。社会工作介入灾后重建,也存在一些问题,如社会工作没纳入救灾体系,缺乏制度性建设;社会工作社会认知度不高,缺乏合法性;社会工作服务无固定经费来源,缺乏保障性;社会工作服务基本靠外来援助,缺乏长期性;社会工作无统一服务标准,缺乏规范性;社会工作服务注重预防与恢复,缺乏发展性等。通过我国灾害社会工作的实践探索,已初步形成可以操作的一定模式,这一行之有效的模式应该是：以政府为主导、以民办社工机构为服务主体、以社区能力建设为主要内容的灾后重建社会工作服务体系。     

近代城市黑幕小说的再审视——以《上海秘幕》及《北京黑幕大观》为中心

文字而冠以黑幕,本就带有浓重的商业炒作色彩,这在小说市场化、商品化的近代城市并不为过。问题在于学界过高期待其匡时警世的社会功能而忽略了其作为文学消费品的消遣娱乐实质,因而毁之赞之,众说纷纭。当下有必要站在客观的立场,重新审视这波一百年前兴起的文学浪潮。     

创化传统融通中外——老舍与赵树理小说的“戏剧性”及其比较

老舍和赵树理小说之所以深受读者喜欢,与其对“戏剧性”元素的创造性借用大有关系.他们在小说情节经营上的戏剧性追求,一方面表现为适时设置假定性情境,激化新的矛盾冲突,使情节环环相扣、曲折多变;同时又注重渲染故事的传奇性,通过设计奇巧的情节或安插突转,以增强读者的阅读趣味和感官冲击.在叙述话语上企慕“出口就响”的口语化、动作性,造就了其小说作品浅近通俗又生动活泼的戏剧性特点.老舍和赵树理还借鉴了传统戏曲的人物“亮相”元素,在主要人物出场时对其进行有选择的形象“拼贴”,成为其作品人物形象和性格达成生动鲜明的重要手段.

项目化教学在软装陈设设计教学中的运用

软装陈设设计作为一种新型艺术学科,广受学生欢迎.其主要是运用相关设计原理,通过不同的视觉效果的传达,从而提出一个给人带来视觉冲击的合适的设计方案.目前,高校中关于软装陈设设计这门学科的相关教学课程不完整和不系统,教学质量还有待改进.这就要求高校在相关教学的过程中,逐渐改变教学方式和方法,巧妙利用项目化教学,提高整个教学的质量.基于此,该文主要针对项目化教学在软装陈设设计教学中的运用进行了探讨.     

A class of nonparametric bivariate survival function estimators for randomly censored and truncated data

This paper proposes a class of nonparametric estimators for the bivariate survival function estimation under both random truncation and random censoring. In practice, the pair of random variables under consideration may have certain parametric relationship. The proposed class of nonparametric estimators uses such parametric information via a data transformation approach and thus provides more accurate estimates than existing methods without using such information. The large sample properties of the new class of estimators and a general guidance of how to find a good data transformation are given. The proposed method is also justified via a simulation study and an application on an economic data set.
