OBJECTIVE To demonstrate feedback-controlled laser-mediated cartilage reshaping using dynamic measurements of tissue optical properties and radiometric surface temperatures. DESIGN Flat cartilage specimens were reshaped into curved configurations using a feedback-controlled laser device. MATERIALS Fresh porcine nasal septum, stripped of perichondrium and cut into uniform strips (25 x 10 x 1...

Recent years have seen the emergence of Web2.0, in which users are not only passive recipients of the featured content, but actively engaged in constructing it. Sites such as ‘Facebook’, ‘Myspace’ are typical examples of this, as are blogs that allow users to present themselves online, to write about their daily lives or even to establish themselves as an authority on a particular subject. Due ...

The purpose of this study was to increase our understanding of applicant perceptions of feedback by drawing upon feedback process models. In Study 1, participants (N1⁄4 125) completed a personality questionnaire as a first stage of a selection simulation. Results showed that the effect of feedback on attitudes toward the organization was mediated by feedback acceptance. In Study 2, participants...

This study investigates the effect of force-feedback in computer-mediated communication. Participants completed a screen-based maze task with an alleged remote participant in a 2 (task characteristics: cooperative vs. competitive) by 2 (modality: haptic/force-feedback vs. visual) balanced, between-participants experiment. There were a number of cross-over interactions. In the competitive task, ...

To have an effective online communication, individuals need to be self-regulated and self-initiate online conversations when needed. Feedback seeking is a key strategy of self-regulated learning through which individuals can gain more knowledge and become more adapted. Existing studies on feedback seeking mainly focus on personal motivation rather than social factors. Drawing on the theory of p...

Purpose – This paper presents a part of our research work that places an emphasis on Tracking Data Analysis and Visualization (TrAVis) tools, a web-based system, designed to enhance online tutoring and learning activities, supported by computer-mediated communication (CMC) tools. TrAVis is particularly dedicated to assist both tutors and students in the task of exploiting tracking data of commu...

The large-scale adoption of computer mediated communication technologies has resulted in what has been described as “mass interaction”, shared discourse between hundreds, thousands or more individuals. A number of theoretical papers have made the argument that because of the existence of various technological and psychological constraints, the forms that mass interaction takes, can, partly be u...

Much attention has been paid to bilateral negotiation in which the dispute is between only two parties. However, automated multilateral negotiation in which more than two negotiating parties need to reach a joint agreement, has received relatively less attention, even though such negotiations are required in many circumstances (e.g. a group of managers making a joint decision for their company ...

All cellular reactions include feedback loops, both positive and negative. Following all receptor-mediated stimulation there are events that activate the cell response and events that dampen the receptor response back to resting conditions. IgE-mediated activation of mast cells and basophils necessarily includes a variety of signaling events that serve to terminate the activation processes. Som...

this study looks at the communication between users concerning health risks, with the aim of exploring their use of fora and assessing whether participants establish a niche with like-minded users during these exchanges. by integrating a corpus linguistic approach with content analysis and multiple studies on computer mediated health discourse, this study analyses the intense attention paid to ...
