This article describes some of the highlights of the author's work with Harold Guetzkow while he was a doctoral student in political science at Northwestern University in the mid-1960s. Harold was a model of professionalism and the author had the great opportunity to learn about the profession during their publication of the "Inter-Nation…

We present a Monte Carlo simulation of a cylindrical luminescent volume and a typical lens-detector system. The results of this simulation yield a graphically simple picture of the regions within the cylindrical volume from which this system detects light. Because the cylindrical volume permits large angles of incidence, we use a modification of…

A simple algorithm was implemented in a spreadsheet program to simulate the circular dichroism spectra of proteins from their secondary structure content and to fit [alpha]-helix, [beta]-sheet, and random coil contents from experimental far-UV circular dichroism spectra. The physical basis of the method is briefly reviewed within the context of…

Participants made categorical or coordinate spatial judgments on the global or local elements of shapes. Stimuli were composed of a horizontal line and two dots. In the Categorical task, participants judged whether the line was above or below the dots. In the Coordinate task, they judged whether the line would fit between the dots. Stimuli were…

Several classroom activities using a model of a seashore and an oil spill demonstrate the basic properties of oil spills in oceans. Students brainstorm about how to best clean up the mess. They work in teams, and after agreeing on how they will proceed, their method is tested by measuring the amount of oil removed and by rating the cleanliness of…

This article addresses modeling oscillation in continuous time. It criticizes Steele and Ferrer's article "Latent Differential Equation Modeling of Self-Regulatory and Coregulatory Affective Processes" (2011), particularly the approximate estimation procedure applied. This procedure is the latent version of the local linear approximation procedure…

Confirmatory factor analytic procedures are routinely implemented to provide evidence of measurement invariance. Current lines of research focus on the accuracy of common analytic steps used in confirmatory factor analysis for invariance testing. However, the few studies that have examined this procedure have done so with perfectly or near…

Steinley and Brusco (2011) presented the results of a huge simulation study aimed at evaluating cluster recovery of mixture model clustering (MMC) both for the situation where the number of clusters is known and is unknown. They derived rather strong conclusions on the basis of this study, especially with regard to the good performance of…

The AACSB requires continuous improvement of business school outcomes through a comprehensive Assurance of Learning program. Measuring ethical decision making poses an interesting challenge for schools making it central to their mission. The authors provide an innovative and effective approach to assessing ethical decision making and closing the…

The Guide to Blended Learning is an introduction using technology and distance education teaching strategies with traditional, face-to-face classroom activities. This Guide has been designed to assist teachers adopt blended learning strategies through a step-by-step approach taking constructivist and design-based approach and reflecting on…

Previous research has shown that ESL students' poor integration into their immersion environments can affect their academic success negatively, which called for structured support for such students. The current study investigated the efficacy of an IEP elective course that was designed to a) promote lower-level students' English use outside the…

Courses in virtual learning environments can leave recently enrolled participants in a state of loneliness, confusion and boredom. What course content is essential in the course, where can more information be found and which assignments are mandatory? Research has stated that learner control and motivation are crucial issues for successful online…

Distance learning has provided an excellent platform for students in geographically remote locations while enabling them to learn at their own pace and convenience. A number of technologies are currently being utilized to conceptualize, design, enhance and foster distance learning. Teleconferences, electronic field trips, podcasts, webinars, video…

Teachers' beliefs about language learning and teaching are largely shaped during pre-service teacher education. Although many empirical studies have analyzed various dimensions of how student teachers' beliefs and practices are formed, the literature is scarce with the research on student teacher's beliefs about oral corrective feedback. For the…

The meaningful knowledge creation about molecular geometry has always been the challenge of chemistry learning. In particular, microscopic world of chemistry science (example, atoms, molecules, structures) used in traditional two dimensional way of chemistry teaching can lead to such problem as students create misconceptions. In recent years,…
