the progress made in the field of information technology has increasingly encouraged social researchers to conduct social studies. researchers employ technology acceptance model (tam, davis, 1984, 1985.2000) to analyze the mechanism and the use it and the social factors affecting it. the attitude towards the computer is one of the variables of tam. the purpose of the present paper is to study t...

with the rapid emergence of 3d applications and virtual environments in computer systems; the need for a new type of interaction device arises. this is because the traditional devices such as mouse, keyboard, and joystick become inefficient and cumbersome within these virtual environments. in other words, evolution of user interfaces shapes the change in the human-computer interaction (hci). in...

This study reports the impact of examining either with digital or paper-based tests in science subjects taught across secondary level. With our method, we compare percentile ranking scores two cohorts earned computer- and teacher-made assessments to find signals a testing mode effect. It was found that overall, at cohort gender levels, pupils were rank-ordered equivalently both modes. Furthermo...

OBJECTIVE This study examined the validity of a computer-based cognitive test that was recently designed to screen the elderly for cognitive impairment. DESIGN Criterion-related validity was examined by comparing test scores of impaired patients and normal control subjects. Construct-related validity was computed through correlations between computer-based subtests and related conventional ne...

BACKGROUND Different methods for changing blood test-ordering behavior in primary care have been proven effective. However, randomized trials comparing these methods are lacking. OBJECTIVE To compare the effect of two versions of BloodLink, a computer-based clinical decision support system, on blood test ordering among general practitioners. DESIGN Randomized trial. SETTING 44 practices o...

an analytical nonlinear stress-strain model and a microscopic damage index for confined and unconfined concretes together with a macroscopic damage index for reinforced concrete (rc) structures under cyclic loading are proposed. in order to eliminate the problem of scale effect, an adjustable finite element computer program was generated to simulate rc structures subjected to cyclic loading. by...

With an incidence of 0.03% of all tumors, carotid body tumors (CBTs) are extremely rare. We present the case of a 63 year old female patient with an asymptomatic right sided neck mass of 3 cm diameter. Doppler ultrasound and contrast-enhanced CT confirmed the clinical suspicion of carotid body tumor. The patient underwent complete surgical excision of the Shamblin group II tumor and an adjacent...
