警察公关礼仪与警察形象的塑造

在现代社会中,任何一个社会组织都要处理好与自身发展密切相关的内外公众关系,树立良好的组织形象。充分重视和发挥公关礼仪的功能和作用是警察组织的形象塑造的一个重要方面。本文对警察公共关系工作中礼仪的功能、原则、意义和养成等方面进行了探讨。认为公共关系是一门塑造形象的艺术,人民警察外在的行为、举止等表现,在人民群众心目中形成的形象、地位、信任和支持程度构成了人民警察的形象。而公关礼仪正是塑造形象这一艺术的起点。     

The Peer Appearance Culture During Adolescence: Gender and Body Mass Variations

The purpose of this research was to examine gender and body mass, as factors linked to perceived experiences within the peer appearance culture. The sample included 215 girls and 200 boys who were either in 7th grade or 10th grade. Students provided self-reports on experiences in three domains: appearance culture among friends (appearance conversations and diet/muscle talk), peer evaluations (peer appearance pressure, appearance teasing, and vicarious peer teasing), and peer acceptance concerns (appearance-based acceptance, peer appearance comparison). The results indicated that although girls reported more appearance conversations, boys perceived more appearance pressure and teasing. Boys also admitted that they talked with friends about muscle building at a rate greater than girls talked about dieting. BMI showed distinct gender patterns. BMI was a key attribute that unified the experiences within the appearance culture for overweight girls. Among the boys, BMI was associated with differentiated experiences for underweight and overweight participants.Associate Professor in Educational Psychology at the University of Washington.

Body Image Concerns in Young Girls: The Role of Peers and Media Prior to Adolescence

Peer and media influences have been identified as important conveyors of socio-cultural ideals in adolescent and preadolescent samples. This study aims to explore peer and media influences in the body image concerns and dieting awareness of younger girls, aged 5–8 years. A sample of 128 girls was recruited from the first 4 years of formal schooling. Individual interviews were conducted to assess the aspects of body image, as well as dieting awareness by means of a brief scenario. A number of sources of peer and media influence were examined. It was found that by 6 years of age, a large number of girls desired a thinner ideal figure. Both peer and media influences emerged as significant predictors of body image and dieting awareness. Specifically, girls’ perceptions of their peers’ body dissatisfaction predicted their own level of body dissatisfaction and dieting awareness. Watching music television shows and reading appearance-focused magazines predicted dieting awareness. In particular, girls who looked at magazines aimed at adult women had greater dissatisfaction with their appearance. Thus, the present study highlights that girls aged 5–8 years of age are already living in an appearance culture in which both peers and the media influence body image and dieting awareness.Hayley Dohnt, B.

"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。     

近代视野下西部民族地区的城市发展——以甘宁青区域为考察对象

在现代性因素的“跃进”性扩散下,以洋务运动为先声,19世纪后期的甘宁青地区也开始了缓慢而曲折的早期现代化进程,城市亦随之出现转型并得到一定发展。但是,由于自然地理环境的先天不足,再加上长期战乱不断、对民族关系问题的认识偏差等后天的人为主观能动性的缺失,较之东、中部等地区而言,近代甘宁青地区的城市发展又表现出明显的滞后性:不仅城市发展缓慢,而且城市早期现代化水平也十分有限,这种滞后的城市发展又对区域的发展造成了严重的消极影响。

论宁南山区农村劳动力结构调整问题
