The purpose of this study was to create a model for examining the relationships between computer-mediated-communication (CMC) apprehension, CMC skill, and CMC presence. Using structural-equation modeling, the study found that CMC apprehension and CMC skill negatively corelated with each other ( .36). Furthermore, CMC apprehension was not shown to relate to CMC presence ( .09), but CMC presence ...

In the investigation of corticomuscular coherence (CMC), it remained unclear why some subjects do not present significant CMC. We predicted that such subjects will develop CMC as a result of learning as indexed by improved performance during a visuomotor task. We investigated CMC, cortical motor spectral power (SP), and performance in 14 subjects during isometric compensation of a static force ...

A consistent finding in computer-mediated communication (CMC) and Internet research is that, compared to face-toface communication, CMC results in higher levels of self-disclosure. We identified four possible mediators that may carry the influence of CMC on self-disclosure: self-presentation, similarity, self-awareness, and direct questioning. The validity of these mediators was tested in an ex...

Mutant mice of mi/mi genotype are osteopetrotic and deficient in tissue mast cells due to a defect in osteoclasts and mast cells. In an effort to further understand the mechanisms behind why mi/mi mouse-derived cultured mast cells (mi/mi-CMC) responded to interleukin-3 (IL-3), but not to the proliferative stimuli presented by fibroblasts, mi/mi-CMC and congenic normal (+/+) mouse-derived CMC (+...

The objective of this study was to assess whether carboxymethyl cellulose- (CMC-) based hydrogel containing BioC (biphasic calcium phosphate (BCP); tricalcium phosphate (TCP) : hydroxyapatite (Hap) = 70 : 30) and bone morphogenic protein-2 (BMP-2) led to greater bone formation than CMC-based hydrogel containing BioC without BMP-2. In order to demonstrate bone formation at 4 and 8 weeks, plain r...

This study integrates the literature on computer anxiety and communication apprehension to determine their joint impact upon individual attitudes toward using and use of computer mediated communication (CMC). We introduce the application-specific CMC anxiety, defined as an individual’s level of fear or apprehension associated with actual or anticipated use of information technology to communica...

Although there are many studies which have observed the overall impacts of Computer-Mediated Communication (CMC) or Information Systems, and many empirical studies which analysed specific impacts partially, there are few studies which have focused on the overall relationship between CMC management and job satisfaction. Therefore, this study aims to clarify the overall CMC impact framework: CMC ...

Tongue movements contribute to oral functions including swallowing, vocalizing, and breathing. Fine tongue movements are regulated through efferent and afferent connections between the cortex and tongue. It has been demonstrated that cortico-muscular coherence (CMC) is reflected at two frequency bands during isometric tongue protrusions: the beta (β) band at 15-35Hz and the low-frequency band a...

Cortico-muscular coherence (CMC) reflects interactions between muscular and cortical activities as detected with EMG and EEG recordings, respectively. Most previous studies utilized EMG rectification for CMC calculation. Yet, recent modeling studies predicted that EMG rectification might have disadvantages for CMC evaluation. In addition, previously the effect of rectification on CMC was estima...
