We consider likelihood based inference in a class of logistic models for case-control studies with a partially observed covariate. The likelihood is a combination of a nonparametric mixture, a parametric likelihood and an empirical likelihood. We prove the asymptotic normality of the maximum likelihood estimator for the regression slope, the asymptotic chisquared distribution of the likelihood ...
Abstract In this special issue, I bring together two studies to provide a comprehensive overview on diverse and interactive instructional methods aimed to facilitate higher levels of learning. One study explored the effects of group interaction using different instructional strategies focusing on the learning process using the Community of Inquiry framework. The other study investigated the eff...
CONTEXT Immigration is a major force sustaining the incidence of tuberculosis (TB) in the United States. OBJECTIVE To describe trends and characteristics of foreign-born persons with TB and the implications for TB program planning and policy development. DESIGN, SETTING, AND SUBJECTS Descriptive analysis of US TB surveillance data from case reports submitted from 1993 to 1998. MAIN OUTCOM...
Many researchers have focused on the question of whether or not there is a difference in learning effectiveness between online and on campus courses. Using the SOLO taxonomy, we explore the quality of learning outcomes of students enrolled in “Computer Network and Internet” classes offered by an institution in wholly online and face to face (blended) learning modes. Students enrolled in the F2F...
The need for better drugs to treat tuberculosis has never been greater. Despite insufficient funding for discovery research, intensive efforts have been made to find and develop new lead compounds capable of reducing the duration of the present treatment known as DOTS (directly observed therapy short course), from 6 to under 4 months. This minireview describes the progress achieved during the l...
We measured hair and plasma concentrations of isoniazid among sixteen children with tuberculosis who underwent personal or video-assisted directly observed therapy and thus had 100% adherence. This study therefore defined typical isoniazid exposure parameters after two months of treatment among fully-adherent patients in both hair and plasma (plasma area under the concentration-time curve, AUC,...
A novel and generic approach named as "history-oriented envisioning" is proposed to qualitatively envision all the possible and the sound situations focusing on our intended partial behaviors and actions of an objective system. Some basic notations called a "partial history" and a "partial situation" are introduced as the extensions of the conventional history and its situations representing qu...
