Aide à la prise en compte de contraintes liées aux utilisateurs lors de la conception d'un hypermédia : une étude auprès de concepteurs de sites Web

This study aims at supporting Web designers to consider more user constraints and addressed why designers focus on client constraints and experience difficulties considering user ones. Novice and professional Web designers had either to deal with ergonomic constraints or to ask an human factors specialist for any information they needed to create a site. Study results showed that client constraints were always considered as preponderant by designers regardless of whether or not they had been prescribed by the client. This contrasts sharply with user constraints which had to be prescribed to designers right from the beginning of their activities in order to be considered and respected.     

The plausibility of spiritual intelligence: spiritual experience,problem solving and neural sites

Australian teachers in Church related schools have begun to use the term ‘spiritual intelligence’ in their educational discourse. Is it accurate to describe spirituality as a form of intelligence? This paper explores whether the notion of spiritual intelligence is plausible. It addresses this firstly by discussing the notion of spiritual experience as a mechanism for problem solving—one of the central themes that underlies the concept of intelligence. Secondly, it examines some of the neural sites of the human brain that have been found to be active in those who apperceive spiritual experience. In light of this discussion, this paper argues that although some concerns prevail in considering spirituality as a form of intelligence, the concept of spiritual intelligence may nonetheless be rendered as plausible.     

Time course of brain activation during graphemic/phonologic processing in reading: an ERP study

The present study sought to investigate the time course of brain activation during grapheme-to-phoneme conversion and phonologic processing of legal Italian syllables. To this goal, we monitored a group of right-handed native Italian volunteers performing a phonologic decision task (same/different judgments). ERPs were recorded from 28 scalp sites during silent reading. Analysis of ERP latency showed faster responses to same syllables than to different ones as early as 105 ms at left temporal electrode site and 160 ms at frontal sites. The first effect of phonologic/graphemic incongruity on the amplitude of ERPs was observed at lateral occipital/posterior temporal sites (N185), where physiologic responses were enhanced to incongruous syllables.     

Social networks and web minorities

The conception of appropriate models of information retrieval is a crucial step for the actual growth and development of the web. In addition to traditional information retrieval techniques, nowadays search engines have adopted methods for taking into account the social network deriving from the pattern of interconnections. Using different arguments, it has been shown that this is very effective in practice. In this paper we subscribe that point of view, but state also that social networks based ranking schemes operating on the whole web, like Google’s , prevent small communities to become visible on the Web, regardless of the quality of the information. Hence, we strongly advocate the development of new cognitive models of the whole process of information retrieval which are capable of facing this problem. We give a picture of distributed architectures which incorporates topic-based intelligent agents and personal agents for capturing the user’s profile.     

社交网站真实自我呈现对生活满意度的影响:线上积极反馈和一般自我概念的链式中介作用

为探讨社交网站真实自我呈现、线上积极反馈、一般自我概念和青少年生活满意度的关系,采用社交网站真实自我呈现问卷、线上积极反馈问卷、一般自我概念量表和生活满意度量表对554名中学生进行调查,结果发现:(1)社交网站真实自我呈现、线上积极反馈、一般自我概念和生活满意度两两之间显著正相关;(2)社交网站真实自我呈现对生活满意度没有直接预测作用,但能通过三条路径的间接作用影响青少年生活满意度:通过线上积极反馈的中介作用;通过一般自我概念的中介作用;通过线上积极反馈和一般自我概念的链式中介作用。研究结果进一步揭示社交网站真实自我呈现对生活满意度的作用机制,能为社交网络时代的青少年发展自我概念与提升生活满意度提供有益建议。     

Facebook as a virtual mosque: the online protest against Innocence of Muslims

When the short anti-Islam film the Innocence of Muslims was first posted on YouTube in English, no tangible reactions were seen in the Arab world. However, when the same producer dubbed it into Arabic and posted it on YouTube, street protests started around some parts of the Arab world. The study reported here examines a popular Facebook page identified as The global campaign to counter the hurtful film against the Prophet Muhammed that was created to protest against the Innocence of Muslims film. This study investigated all 6949 Facebook updates and comments that were available on this page by 15 October 2012 and found that a clear majority of posts were Pro-Islamic focusing on prayers for Muhammed and supplications to defend him. This study advances our theoretical understanding of the connection between online and offline religion by providing empirical evidence in relation to this controversial incident.     

社交网站中的自我呈现对青少年友谊质量的影响:积极反馈的中介作用

随着网络的日益普及,社交网站已成为人们活动的新领域和人际交往的新媒介。为探讨社交网站中不同的自我呈现方式、积极反馈与友谊质量的关系,采用问卷法对来自武汉市两所普通中学的817名10~19岁的学生进行调查,其中,男生423人,女生366人。研究采用偏差矫正的百分位Bootstrap法,使用Hayes(2012)编制的SPSS宏对中介效应进行检验,结果发现:(1)真实自我呈现和积极自我呈现与积极反馈、友谊质量显著正相关;(2)社交网站中的真实自我呈现既能直接预测青少年的友谊质量,也能通过积极反馈的中介作用对友谊质量产生影响,而积极自我呈现对青少年的友谊质量没有直接预测作用,只能通过积极反馈的完全中介作用对友谊质量产生影响。     

社交网站支持对大学生社交网站成瘾的影响:有调节的中介模型

探讨社交网站支持对大学生社交网站成瘾的影响机制.采用社交网站支持量表、感觉寻求量表、错失恐惧量表和社交网站成瘾量表对501名大学生进行调查.结果发现:(1)社交网站支持正向预测大学生社交网站成瘾;(2)错失恐惧在社交网站支持与大学生社交网站成瘾间起部分中介作用;(3)感觉寻求调节了社交网站支持对大学生社交网站成瘾的影响...     

自恋与社交网站使用的关系

自恋作为一种人格特质,以膨胀的自我概念、寻求他人持续的关注和肯定为主要特征,而社交网站鼓励多种形式的自我提升行为,深受自恋者的喜欢。在考察社交网站上的一般性使用行为、不同类型社交平台上、不同性质的使用行为以及具体的使用行为时,均发现了自恋的显著预测作用(自我选择效应);不同形式的社交网站使用行为也会强化个体的自恋水平(媒体效应)。自恋和社交网站使用之间相互作用、相互强化(强化螺旋模型)。两者的关系还受性别、年龄和代际差异以及文化等因素的影响。未来研究还需进一步探讨自恋和社交网站使用行为的界定及测量、两者的作用方向以及研究方法的改进等问题。     

社交网站使用与妒忌:向上社会比较的中介作用及自尊的调节作用

采用方便抽样法对630名具有社交网站使用经验的大学生进行问卷调查,探讨社交网站使用对妒忌的影响,以及向上社会比较、自尊在其中的作用机制。结果表明:(1)社交网站使用显著正向预测妒忌;(2)向上社会比较在社交网站使用与妒忌之间起部分中介作用;(3)该中介效应受到自尊的调节。具体来说,相对于高自尊大学生,低自尊大学生的向上社会比较产生更多妒忌。
