Some problems in interracial communication: An interracial group case study

An interracial group case study has revealed that sensitization, lack of shared experience, stereotyping, racial intragroup pressures, and variables in physical environment all contribute in varying degrees to the problems arising in interracial interaction.     

The impact of technology and a no remediation policy on non-traditional students

A Hunter College librarian, with public library experience, offered a series of drop-in workshops Saturday afternoons open to all students and questions regarding Web or Windows use in the academic year, 2000-2001. The intention of the workshops was to address the continuous needs of students lacking technological and informational literacy. The success of these workshops led to this investigation of the implications of 21st century technology on non-traditional students from the perspective of bibliographic instruction as well as reference desk service. The perspective is that of the urban educational environment of City University of New York and Hunter College. The histories of open admissions at CUNY and the current efforts to abolish remediation are examined.

Mirroring the Media: The Relationship Between Media Consumption,Media Internalization,and Profile Picture Characteristics on Facebook

Social cognitive theory suggests that stereotypes of attractiveness from mainstream media may function as models for online profile pictures. The present study explores the relationship between media consumption, internalization, and body-ism, clothing, and gaze through a content analysis of the Facebook profile pictures of 288 students, and a survey to assess their media consumption and internalization. The relationship between magazine exposure and pictures was mediated by internalization: magazine readers who internalized media ideals were more likely to select pictures showing their body in revealing clothing. Television viewing had a direct effect on picture selection, but was not mediated by internalization.     

Nothing to Fear? An Analysis of College Students' Fear Experiences With Video Games

This study presents the results of a survey of 269 undergraduate students conducted to examine fright experiences caused by video games. Over half of the participants reported game-induced fear. Sex, sensation-seeking, and empathy all emerged as important individual differences in terms of enjoyment of frightening content, consumption of frightening content, and frequency of fright experience. Interactivity and presentations of realism also predicted fear. This work identifies titles, stimuli, and features that caused fright experience.     

青少年运动缺乏症研究的10大问题

摘要：运动缺乏症（EDD）是一种儿科疾病,特点是中高强度体力活动（MVPA）下降,低于目前的推荐量,也与积极的健康结果（health outcomes）不一致。目前,大多数儿童和青少年符合EDD的诊断标准,因为他们没有达到日常MVPA的最低要求。本文的目的是强调10个与青少年EDD有关的重要研究问题。需要进行重要的研究来更好的定义EDD的临床表现,包括评估体力活动行以确定开始出现EDD的年龄或发育阶段;包括运动技巧和体能的运动起源（kinesiogenesis）的检测;以及对影响青少年MVPA的生活方式因素的评估。关于治疗EDD的干预措施和政策的研究问题,包括评估对卫生保健从业者进行运动医学重要性的教育和训练;确定在临床上识别和治疗EDD青少年的方法的有效性;开发敏感的、特效的、经济的方法以诊断青少年EDD;以及定制方法以促进本病诊疗的医疗保险赔付。如果未来研究不能优化EDD青少年的识别、治疗和管理方案,具有重大影响的生物医学、心理、经济和政治的新的卫生保健问题将会不断出现。
