信息污染是信息传播中的一种异化现象。目前,信息污染正以多种表现形式作用于高校校园,给高校思想政治教育教学带来一定的影响。就大学生而言,信息污染导致大学生出现新的信息匮乏,冲击大学生主流意识形态,造成大学生对社会的认知偏差及引发大学生信息污染疾病;从思想政治教育教学本身而言,信息污染使得教育教学环境更加复杂,教师的权威地位被消解、教育教学内容不可控制、教育教学方法亟待变革、教育教学目的难以实现。 相似文献

目前,在大量快速传递的有用或有益的信息中混杂了一些伪劣的信息,包括无用的、虚假的、反道德、不健康的内容等,这就是信息污染。信息污染是因为“信息量成指数增加”、“信息爆炸”、信息质量低下、信息传播过程中的各种干扰和破坏引起的。而且由于信息传播方便,污染后的信息又被迅速传播出去,造成更大的污染。信息污染主要表现在五个方面: 相似文献

信息不对称在环境规制过程中普遍存在。基于信息不对称和治理成本两个基本变量条件下的企业间污染治理决策进行静态和动态博弈分析,通过分析发现：信息不对称环境下,污染企业都有率先不进行污染治理的环境机会主义动机,若治理成本在可承受范围内,污染企业环境治理决策与信息不对称产生的机会主义空间大小关系更为密切。 相似文献

Dorothy Williams Louisa Coles 《Educational research; a review for teachers and all concerned with progress in education》2013,55(2):185-206
Background The use of research evidence produced by others is seen as central to the reflective practice of school teachers. There have been many recent UK initiatives aimed at improving access to research evidence, but there are still concerns about the lack of engagement by teachers. Previous research has looked at this issue from different perspectives, including the content and relevance of educational research, the relationships between researchers and teachers, accessibility and presentation of research and the culture of the school. The research presented here seeks to make a contribution to understanding the diffusion of research in the teaching profession by examining the issues from an information literacy perspective. Purpose This paper examines the use of research information by UK school teachers, placing an emphasis on their information literacy—i.e. teachers' strategies and confidence in their abilities to find, evaluate and use research information, which is defined as the published output of a planned piece of research. Sample Survey data were collected from 312 teachers and 78 head teachers from nursery, primary and secondary schools in Scotland, England and Wales. The sample included a wide range of teaching experience, ages, subject responsibilities, school locations and sizes, although there was a bias towards teachers who were motivated to use research evidence. Interviews were conducted with 28 teachers from primary, secondary, nursery and special education schools, and a further 15 teachers took part in group exercises. Interview and group exercise samples were more varied in their levels of research involvement. Design and methods A mixed methodology was used. The questionnaire survey sought background data on more general attitudes towards research, as well as data on information access and confidence in finding and using general and research information. This was supplemented by qualitative evidence on information strategies and experiences from scenario or vignette interviews. Group exercises in which teachers discussed their responses to specific examples of research information were useful in focusing on strategies for evaluating information. Results While survey respondents were, on balance, positively motivated towards the use of research evidence, their actual use of information from research was limited. They considered the most prominent barriers to their use of research information were associated with lack of time and lack of ready access to sources. This is likely to be a limiting factor in terms of the development of teacher confidence in finding, evaluating and using the kinds of information sources which are increasingly available to support their professional development. In fact survey evidence from the more research-motivated sample indicated that teachers were considerably less confident in finding and using research information than general information. Their confidence was slightly higher in finding research information (e.g. 67.1% and 60.9% were either confident or very confident in defining information needs and locating information respectively) compared to using research information (for example, 56.5% were either confident or very confident in organizing and synthesizing information). However, evidence from the more mixed interview and group exercise samples also revealed a range of concerns about lack of skills and knowledge needed to search and evaluate information effectively. Conclusions The findings suggest that information literacy may be a factor in limiting the use of research information, exacerbating the perceived challenges of lack of time and lack of ready access to information sources. From an information perspective, teachers' use of research evidence is likely to be enhanced by greater development of information literacy; more attention to local information dissemination strategies; and the development of an information culture and ethos within schools. 相似文献

The current study uses a grounded theory approach to explore dimensions and bi-national comparisons of active information seeking efforts (seeking) for and passive information acquisition (scanning) of drug-related information among two college student samples from the United States (N = 25) and Israel (N = 39). Specifically, the study focuses on seeking and scanning related to amphetamines and marijuana, two frequently used drugs among college populations, about which information is easily accessible. Results of semi-structured interviews suggest that information scanning and seeking about marijuana and amphetamines are common, particularly from peers and from the Internet. The analysis uncovers themes relating to young adults’ drug-related, information-seeking behaviors, including cross-source information acquisition across interpersonal and media sources, and motivations for engaging in active efforts to seek drug-related information. These findings extend research on information seeking and scanning and suggest future research should examine predictors and effects of these behaviors in the context of substance use. 相似文献
