马歇尔·麦克卢汉以其“媒介即讯息”、“媒介是人的延伸”、“地球村”以及“外爆”和“内爆”等论点和概念闻名于世。让·博德里亚力图发展麦克卢汉的媒介技术文化的学术观点，但他强调的是媒介重要性而不是讯息的重要性，他在将注意力集中于对麦克卢汉的“内爆”和即时传播的各种概念作了激进化的处理之后，提出了自己的电子媒介技术及其文化批评理论的三个关键词：仿真、内爆和超真实。这是博德里亚建立其电子媒介文化批评理论的核心和关键，是他描述技术媒介运作规律的中心概念。要理解博德里亚的理论，必先厘清这三个关键概念。 相似文献

Microfluidic-based protein arrays are promising tools for life sciences, with increased sensitivity and specificity. One of the drawbacks of this technology is the need to create fresh surface chemistry for protein immobilization at the beginning of each experiment. In this work, we attempted to include the process of surface functionalization as part of the fabrication of the device, which would substitute the time consuming step of surface functionalization at the beginning of each protein array experiment. To this end, we employed a novel surface modification using self-assembled monolayers (SAMs) to immobilize biomolecules within the channels of a polydimethylsiloxane (PDMS) integrated microfluidic device. As a model, we present a general method for depositing siloxane-anchored SAMs, with 1-undecyl-thioacetate-trichlorosilane (C11TA) on the silica surfaces. The process involved developing PDMS-compatible conditions for both SAM deposition and functional group activation. We successfully demonstrated the ability to produce, within an integrated microfluidic channel, a C11TA monolayer with a covalently conjugated antibody. The antibody could then bind its antigen with a high signal to background ratio. We further demonstrated that the antibody was still active after storage of the device for a week. Integration of the surface chemistry into the device as part of its fabrication process has potential to significantly simplify and shorten many experimental procedures involving microfluidic–based protein arrays. In turn, this will allow for broader dissemination of this important technology. 相似文献

A growing body of research in recent years has supported the value of emotional intelligence in both effective teaching and student achievement. This paper presents a pre–post, quasi-experimental design study conducted to evaluate the contributions of a 56-h “Emotional Intelligence” training model. The model has been developed and studied in an attempt to address educators’ growing needs to practice and implement “emotionally intelligent” learning environments. One hundred eighty-six teachers from ten elementary schools in Israel participated in this study. Findings indicated an increase in emotional intelligence and empathic concern from the beginning to the end of the course. Further regression indicated that both expression and regulation of emotions predicted empathy at the end of the course. Participants’ reflective assignments indicated an increase in self introspection, emotional awareness, emotional regulation and understanding others. 相似文献

Many college students consider statistical courses as frightening and demanding, yielding high anxiety and low competence, and correlating with maladaptive academic behaviors and low achievement. With undergraduate students, the present pre-post study compared a supportive online teaching program utilizing mandatory statistical exercises (n = 37) with a no intervention, optional exercise statistics class (n = 32). We evaluated whether our statistics teaching intervention decreased test anxiety and academic procrastination and increased academic self-efficacy and academic achievements. Results indicated a decrease in academic procrastination and test anxiety at course end for intervention group and an increase in test anxiety for control group. At the end of the course intervention group reported higher academic self-efficacy and achievements. Teaching statistics using mandatory supportive activities might contribute to more positive psychological outcomes (eg, higher academic self-efficacy and lower academic procrastination) and higher academic achievements. 相似文献

This study investigated associations between student-perceived teacher behaviours and students’ personal goal orientations. Thus, the study applied theoretical concepts from self-determination theory and parenting style in an attempt to enhance understanding of additional environmental characteristics possibly affecting personal goal orientation. Moreover, it examined psychological control in a classroom context, whereas it was previously investigated mainly within parent–child relationships. Junior-high school students (n?=?191) completed questionnaires to reveal their perceptions of teacher practices and their own personal goals. The distinction between teachers’ psychological control and autonomy suppression was supported by confirmatory factor analysis; however, they were highly correlated. When regarded as two dimensions of teachers’ compelling behaviours, they associated positively with performance-approach and performance-avoidance goals and negatively with mastery goals. Teachers are advised to avoid various compelling practices. 相似文献
