信息传播媒体对农村小学生学习成绩的影响——以电视、电脑和手机为例

利用大规模随机抽样调查数据,分析了农村小学生看电视、用电脑和手机等信息传播媒体对他们学习成绩的影响,发现周间和周末使用这些传播媒体对学习成绩影响不同。看电视可以满足他们的娱乐和信息需求,周末适量地收看电视节目与他们的学习成绩之间呈现正相关关系;由于电脑和手机在农村小学生手中只充当游戏机的功能,使用这些媒体的时间与他们的学习成绩之间存在负相关关系,并且使用这些媒体的时间和对学习成绩的影响在男女生之间存在显著差异。     

Enacted Goal Attention in Family Conversations about End-of-life Health Decisions

Most extant research on end-of-life communication in families has been based on the assumption that more communication is better communication. We used a multiple goals theoretical perspective to demonstrate that the quality of communication about end-of-life decisions matters. Members of 121 older parent/adult child dyads (N = 242) engaged in an elicited conversation about end-of-life health choices and reported their assessments of the conversation. Using multilevel linear modeling, we found that outside ratings of a person's communication quality (i.e., attention to task, identity, and relational goals) as well as outside ratings of the partner's communication quality were positively associated with the person's reported conversational satisfaction and hopefulness and negatively associated with the person's hurt feelings and relational distancing.     

Sibling communication satisfaction as a function of interpersonal solidarity,individualized trust,and self‐disclosure

The purpose of this study was to examine sibling communication satisfaction, with a specific focus on interpersonal solidarity, individualized trust, and self‐disclosure. Respondents (N = 360) were asked to report on a relationship with either an older sister, younger sister, older brother, or younger brother. Results indicate that interpersonal solidarity is the largest predictor of sibling communication satisfaction, followed by individualized trust, and self‐disclosure.     

Spaces of emergent memory: Detroit’s 8 Mile wall and public memories of civil rights injustice

This article introduces emergent memory, a conceptual extension to rhetorics of public memory, to describe memory’s genesis in sites built without commemorative commitments. Examining Detroit’s “8 Mile Wall,” a site built to reinforce segregated housing, this project argues the rhetorical tenets of emergent memory present in this space. As a relic of segregated history, the wall symbolically recalls the city’s controversial past, but has recently been the subject of a local mural project to redefine the wall’s purpose. Some consider this a step toward reclamation, as it visually repositions the disturbing remnant. For others, the murals simply cannot overwrite troubling memories of the city’s discriminatory history. This essay uses emergent memory to describe how the wall’s complicated mnemonic legacy simultaneously harkens to a difficult history and how the mural additions use that same legacy to convey an optimistic future for Detroit and those marked by this urban space.     

Writing in Mathematics: An Alternative Form of Communication for Academically Low‐Achieving Students

Abstract. Classroom communication figures prominently in current math reform efforts. In this study, we analyze how one teacher used writing to support communication in a seventh‐grade, low‐track mathematics class. For one school year, we studied four low‐achieving students in the class. Students wrote in journals on a weekly basis. Using classroom observations and interviews with the teacher, we developed profiles of the four students, capturing their participation in class discussions. The profiles highlighted an important similarity among the four students: marginal participation in both small‐group and whole‐class discussions. However, our analysis of the students' journals identified multiple instances where the students were able to explain their mathematical reasoning, revealing their conceptual understanding, ability to explain, and skill at representing a problem. In this respect, journals potentially facilitate another important form of classroom communication. The promise of writing is that it offers an alternative to the visions of classroom communication that are strictly oral in nature.
