关于中国现代史分期问题的思考

目前,史学界对于中国现代史的分期看法不一,形成不同的主张：或以重大政治历史事件为标准,或依据《关于建国以来党的若干历史问题的决议》,或以经济社会发展目标模式为分期标准。这些标准都不符合中国通史的学科分期要求。中国现代史作为通史,其分期应当以社会形态的变迁为标准,应根据社会主义的不同发展模式,将其划分为新民主主义时期或社会主义的准备时期、苏联模式社会主义时期或传统社会主义时期、中国特色社会主义时期或现代社会主义时期。     

试论中国政府形象构建的路径选择——以全球化为背景

良好的政府形象是政府巩固统治合法性的基础,是社会稳定和发展的必要条件,也是政府赢得国际良好声誉的保障。在全球化背景下,政府形象本身所承载的价值也被提升和扩展到全球,因此政府形象构建面临着前所未有的压力和挑战。就我国政府形象构建而言,应进一步增强形象塑造意识,着力构建能力型政府和开放型透明政府,以构建起理想的政府形象体系。     

提炼嘉兴主题文化彰显禾城特色魅力——嘉兴城市主题文化建设构想

为了彰显嘉兴城市的特色魅力,必须提炼嘉兴主题文化。基于嘉兴城市文化的基本特点和嘉兴城市的独特元素,根据城市主题文化提炼的5个原则,嘉兴城市主题文化可以提炼为"棹歌会府,粽子都会",并可从三个方面来构建:一是"以‘棹歌升处,粽香天下’进行城市宣传,推介嘉兴历史文化名城的新形象";二是"以‘棹歌’、‘粽子’进行文化创意,打造嘉兴文化创意产业的新起点";三是"以‘棹歌’、‘粽子’进行视觉形象塑造,构筑嘉兴城市生活的新环境"。     

论散文创作与图像艺术的审美互生——以西部散文为例

图像艺术与话语文本的结合是文学创作中的一个重要命题。随着当代视觉艺术的发展,文学创作的视觉化趋势更加明显,并体现在图像艺术与文学话语的结构组合与意蕴融合中。文心画意是散文家自觉的审美追求,影响着散文的叙事、写景与抒情。西部散文中就有许多图文并茂的作品集,成为散文创作与图像艺术审美互生的艺术表征。     

西南联大时期的许宝騄与戴世光

许宝騄、戴世光是我国近现代数理统计和社会经济统计领域的两面旗帜。他们二位在上世纪30年代分别留学英国和美国，获得统计学博士和硕士学位。抗日战争爆发后，分别在1940年、1938年回到昆明，任教西南联大。在极其困难的条件下，他们不仅在算学系、经济学系系统讲授数理统计和社会经济统计等课程，而且作出了有重大国际影响的研究成果。艰苦而乐观的生活趣事既反映了当时特殊的时代背景，更彰显出他们高尚的人格品德。     

Never easy to say “sorry”: Exploring the interplay of crisis involvement,brand image,and message appeal in developing effective corporate apologies

This study examines how the interplay among crisis involvement, brand image, and message appeal impacts the effectiveness of an apology in the context of a corporate crisis. To determine apology effectiveness, a 2 (crisis involvement: high vs. low) × 2 (brand image: symbolic vs. functional) × 2 (message appeal type: emotional vs. informational) experimental design was employed. The results demonstrate that the three-way interaction is significant, especially in the low-crisis involvement condition. The study concludes with a discussion of theoretical and practical implications and directions for future research.

A robust automatic clustering algorithm for probability density functions with application to categorizing color images

This study develops a robust automatic algorithm for clustering probability density functions based on the previous research. Unlike other existing methods that often pre-determine the number of clusters, this method can self-organize data groups based on the original data structure. The proposed clustering method is also robust in regards to noise. Three examples of synthetic data and a real-world COREL dataset are utilized to illustrate the accurateness and effectiveness of the proposed approach.     

Business reform outcomes: Why so different?

Post-crisis policy making increasingly focuses on doing business reforms. We argue that the effects of those reforms will be different across countries. To understand the reasons for the reform outcome divergence, we advance a novel firm-size distribution (FSDs) argument. At the center of the argument is the fact that FSDs are different across countries and stable over time. Then, if a given doing business reform induces firms of different size to grow differently, this will produce a variety of reform outcomes across countries. To advance the argument, we set up a tractable general equilibrium (GE) model and study how firms of different size grow after a doing business reform. The model predicts that larger firms will grow faster than smaller firms after the reform. The model predictions are tested on the Enterprise Surveys (ES) data, merged with the Doing Business indicators. We confirm that firms of different size grow differently after a Doing Business reform. Thus, based on the notable differences of firm size distributions across countries, identical reforms to start, operate and close a business will produce a variety of reform outcomes across countries.
