introduction: citation tracking is a bibliometrics method to analyze the scientific impact of journal articles which can be done through scopus (sc), google scholar (gs), or isi web of knowledge (wos). in the current study, we analyzed the citations to 2006-2012 articles of iranian journal of nuclear medicine (ijnm) in the sc and gs. methods: we retrieved the relevant data from sc and gs offici...

The sinewave generators based the switched-capacitor (SC) technologies are implemented in transistor level. This analogue sinewave generator consists of two parts: an approximate sinewave generator and a filter. The structure of this generator is robust and easily-controlled, in which an approximate sinewave is firstly generated based on SC circuits and then filter the harmonics. The main advan...

social capital (sc) is important as much as physical capital and theorists discussed its functions in enhancement of countries. successfulness in international fields is far behind reach without due attention to capacity of countries. these capacities are known as competitiveness capacity (cc) in political literature. twelve indexes have been recognized for the cc which covers different dimensi...

We describe the design of Instructor Rating Markets in which students trade on the ratings that will be received by instructors, with new ratings revealed every two weeks. The markets provide useful dynamic feedback to instructors on the progress of their class, while at the same time enabling the controlled study of prediction markets where traders can affect the outcomes they are trading on. ...

Much of the debate surrounding the use of lecture-based classes as a method for teaching science has focused on the passive role assumed by students in lecture (1, 2, 3). The communication channel is primarily instructor-to-student. Numerous studies have shown that student performance in science classes improves with increasing levels of active participation by students in classroom discussions...

Students' judgments of their own learning are often misled by perceptions of fluency-the ease with which information is presented during learning. Lectures represent important learning experiences that contain variations in fluency, but have not been extensively studied. In the current study, students watched a 22-min videotaped lecture that was delivered by the same instructor in either a flue...
