网络中的人际传播   总被引:15,自引:0,他引:15  
人际传播是网络中最常见的传播形态之一。对网上人际传播的需求 ,使网络日益成为人们生活的一部分。人际传播也与网络中的其它传播形态相互交融、相互作用。本文对网络人际传播的方式、特点进行了初步的研究分析 ,并以此说明网络人际传播对于物理世界人际传播活动、人的社会化等方面可能带来的影响。最后本文探讨了受众和传播者如何利用网络人际传播的问题。  相似文献

网络假新闻的不断出现,对新闻的真实性造成了很大的影响。把握好新闻的真实性,关系到网络媒体的公信力。那么,到底如何把握好新闻真实性呢?首先要加强对互联网站的管理,建立健全一整套的网站新闻信息采制发布的审查把关制度,其次要严厉地打击利用网络制造和传播虚假信息、造谣惑众的行动,第三,网站要增强社会道德感和责任感,网络从业人员要提高自己各方面的素质,提高自己对信息的辨别力。同时,也要培养受众的防范意识,使他们不轻信、不传布未经证实的信息。  相似文献

The aim of this study was to investigate the relationships between aspects of organisational communication and dimensions of job satisfaction and general organisational commitment. Participants were 358 staff members from 35 government primary schools in the state of Western Australia, who completed a survey comprising the Organisational Communication in Primary Schools Questionnaire, the Teacher Job Satisfaction Questionnaire and a five item general organisational commitment scale. Factor analyses established 13 aspects of job satisfaction and 9 dimensions of job satisfaction. Multiple regression analyses were used to investigate interrelationships. The findings suggest several aspects of organisational communication were related to job satisfaction and organisational commitment. This article concludes with implications for future research with regard to communication and for the maintenance of optimal levels of job satisfaction and commitment in schools.  相似文献

Capital‐embedded parental involvement in education is essential in enhancing university enrolment and maximising the educational potentials for equality and excellence. Previous studies in this field have mainly utilised Perna's ( 2000 , 2006 ) model, which defines parental involvement as social capital and identifies the additive influences of different types of capital (including social, economic and cultural capital) on university access and choice. Yet, little research to date theorises and disaggregates the interplay among various types of capital as well as the multiplicative capital effects on enrolment. This study addressed this gap. We proposed an ‘interacting multiple capitals’ (IMC) model and hypothesised that parental social capital could moderate the effects of cultural and economic capital on entry to university. To validate the model, a pilot survey was administered to 216 university students of Korean ethnicity in China and investigated the models of involvement adopted by Korean parents in the context of the increasing labour mobility of the Korean adult population. Moderated multiple regression analysis was employed and the results confirmed the hypothesis that capital effects upon university access and choice were multiplicative in nature, with social capital moderating the cultural capital influence on students’ educational aspirations. The study findings show that the interaction of various types of capital variables is sufficiently statistically significant to warrant future research and policy and practical discussion of how to promote parental involvement in university preparation and planning.  相似文献

The study presented in this article forms part of a wider project promoting collaboration between junior researchers from different universities with the objective of rethinking and improving teaching practice in relation to the use of technology. The article describes research carried out during the 2012/13 academic year aimed at developing collaborative action research through technologically mediated agoras involving students from three Spanish universities. The main results of this study show that junior researchers improved their teaching practice through technologically mediated inside and outside agoras. In addition, the transformation of university classrooms into agoras enabled the negotiated reconstruction of knowledge for the analysis of good practice in the use of technology. Likewise, these agoras helped reduce limitations by breaking down the barriers of time, distance and resources for sharing findings and limitations between junior researchers. Furthermore, they pave the way for improvements and their implementation in learning processes during initial teacher training.  相似文献

This paper proposes a design framework to support science education through blended learning, based on a participatory and interactive approach supported by ICT-based tools, called Science Learning Activities Model (SLAM). The development of this design framework started as a response to complex changes in society and education (e.g. high turnover rate of knowledge, changing labour market), which require a more creative response of learners to the world problems that surround them. Many of these challenges are related to science and it would be expected that students are attracted to science, however the contrary is the case. One of the origins of this disinterest can be found in the way science is taught. Therefore, after reviewing the relevant literature we propose the SLAM framework as a tool to aid the design of science courses with high motivational impact on students. The framework is concerned with the assumption that science learning activities should be applicable and relevant to contemporary life and transferable to ‘real-world’ situations. The design framework proposes three design dimensions: context, technology and pedagogy, and aims at integrating learning in formal and informal contexts through blended learning scenarios by using today’s flexible, interactive and immersive technologies (e.g. mobile, augmented reality, virtual reality).  相似文献

Educational literature shows that students from working-class backgrounds are significantly less likely to persist to completion in higher education than middle-class students. This paper draws theoretically and analytically on Bernstein’s ([1990. Class, Codes and Control, Volume IV: The Structuring of Pedagogic Discourse. London: Routledge; 2000. Pedagogy, Symbolic Control, and Identity: Theory, Research, Critique. Lanham: Rowman and Littlefield]) thesis that, through differential framing of pedagogic practices, the curriculum has capacity to accommodate all groups of students. Pedagogic practices in both a science foundation course and four first-year mainstream science courses in a higher education institution in the South African context are examined. Whilst the foundation course exhibits modalities that generally favour access, the mainstream courses have some modalities that appear to be constraining. It is argued from a social justice perspective that holistic curriculum transformations that better enable epistemic transitions are an urgent imperative, and that consideration of differential framing of pedagogic modalities offer a close-up empirical means of conceptualising such reforms.  相似文献

从开放式创新视角讨论了二次创新对创新绩效的影响。基于一个两阶段模型,阐述了内向型与外向型、二次创新对创新绩效的作用机制。以高新技术企业为样本进行了分析,结果发现内向型企业更倾向于选择二次创新;二次创新负向调节内向型与创新绩效之间的关系,正向调节外向型与创新绩效之间的关系。  相似文献

在数字通信中,信道的多径传播和衰落特性常在接收端引起码间干扰(ISI)并降低信噪比,严重影响了通信质量。本文研究了空间分集与盲均衡相结合的空间分集均衡技术(SDE),提出了一种基于等增益合并和判决反馈盲均衡的空间分集均衡算法,以克服码间干扰并消除衰落对通信系统所带来的不利影响。通过计算机仿真对空间分集均衡算法和传统盲均衡算法的性能进行了对比,结果表明空间分集均衡技术优于传统的盲均衡技术,提高了数字通信性能。  相似文献
