"我靠虚像生活"--媒介环境的影像阐释

大众传媒越来越深度地参与社会生活,我们对客观现实的认识也越来越依赖大众传媒,现实环境逐渐演变为媒介环境。媒介环境呈现出鲜明的影像特征,“我靠虚像生活”已经成为一种生存状态。运用昆德拉的“意象形态”、柏拉图的“洞穴理论”、李普曼的“拟态环境”、藤竹晓的“拟态环境的环境化”、鲍德里亚的“仿真、超真实、内爆”等理论,可以对此进行不同角度的阐述。公众把媒介环境的影像当成客观环境的真实来把握,就会落入“托马斯公理”所预言的圈套之中,可能使错误理解成为现实。     

世俗化时代的身份变异——当代女性文学中母亲形象的一种写作方式

1990年代以来的世俗化潮流极大影响了包括女性文学在内的当代文学写作.女性文学写作对女性重要角色--母亲身份的质疑与反思,成为引人注目的文学现象,彰显出女性写作的独特意义.对母亲欲望化情感的书写和母女情感的去魅是女性文学写作的两种重要叙事策略,由此实现了母亲形象的世俗化还原,动摇、冲击着男权话语的权力结构.     

Factors Contributing to Gender Differences in Depressive Symptoms: A Test of Three Developmental Models

In a longitudinal study on 115 early adolescents, the impact of major events, relationship stressors, and coping style in interaction with biological changes on depressive outcome in late adolescence were explored. Three developmental models proposed by Nolen-Hoeksema and Girgus (1994, Psychol. Bull. 115: 424–433), which attempt to explain the emergence of gender differences in adolescent depressive symptoms, were tested. Multiple regression analyses conducted to test Model 1 identified two etiological factors associated with gender differences of depression, namely, stress in the adolescent–mother relationship and a more negative body image. Tests of Model 2 revealed etiological factors which correlated with depression in adolescent girls but not adolescent boys. The correlational patterns of avoidant coping and body image emerged as relevant factors for Model 2. Finally, tests of Model 3 searched for factors which were more likely to be observed in adolescent girls than boys and which would put girls at risk should they interact with a third etiological factor. Early maturational timing emerged as a factor for Model 3.     

体外培养FBs损伤模型的建立及细胞免疫组化研究

首次应用培养人胎肺成纤维细胞 (FBs)损伤模型 ,体外研究创缘FBs合成细胞型纤维连接蛋白 (cellu larfibronectins,cFn)的变化与损伤时间的关系。结果表明 ,损伤使处于静息状态的融合FBs成为具有运动能力和增殖能力的活跃细胞。应用免疫组化ABC法结合图像分析技术 ,观察伤后不同时间创缘FBs内cFn的含量变化。伤后 1h ,可以检测到cFn有变化 ,且在伤后 6h内 ,cFn逐渐增多 ,其变化与损伤时间呈正相关。这对今后应用cFn与损伤时间推断的研究提供了科学依据 ,同时为法医学损伤时间研究开辟了新的途径。     

Adolescent Boys and Body Image: Weight and Muscularity Concerns as Dual Pathways to Body Dissatisfaction

This research evaluated a dual pathway model for body dissatisfaction among adolescent boys. The study provides empirical support for the importance of distinguishing between weight and muscularity concerns in understanding male body image. A total of 128 boys from grades 8 and 11 completed a self-report questionnaire. Results indicated that weight and muscularity concerns each made unique contributions to body dissatisfaction and were associated with distinct individual and peer context characteristics. Weight concern was associated with elevated BMI and more frequent appearance conversations with friends. Muscularity concern was significantly greater among boys who reported more frequent muscle-building conversations, had lower BMI, and were older. The results support the importance of distinguishing between and assessing both muscularity and weight concerns in the development of body image dissatisfaction among adolescent boys.     

一种基于Otsu算法的印章二值化算法

本文提出了一种基于Otsu算法的印章二值化法.该算法通过对算法的改进,考虑了印章图象象素的灰度分布值和它们邻域象素的平均灰度值分布情况.并不是用于整幅印章图象,而是用于分块的印章图象.实验证明,该算法适合印章的二值化处理.

杨柳：江南区域文化的典型象征

从先秦到汉唐,杨柳在北方的分布十分普遍,其文化表现也以北方为主.中晚唐以来,杨柳意象则明显南方化,逐步成为江南风景和文化的典型象征.这一历史转变与北方地区生态环境的整体衰退,社会经济、文化重心的南北转移,杨柳自身的品种结构变化密切相关.作为江南意象的杨柳,包含着物华饶美、水乡清柔、风俗奢乐等多重象征意蕴.     

论警察与媒体的通融

构筑警方与媒体的和谐是我们的应有之义。改善和发展警察公共关系需要借助媒体的力量,良好的媒体关系有助于提升警察形象。媒体是警察与公众联系的桥梁和纽带,警方借助媒体发布正面的信息从而争取公众对警察工作的支持,使“执法者”与服务对象融为一体,共同维护治安、打击犯罪。
