An important activity in urban three-dimensional (3D) mobile navigation is browsing the buildings in the environment and matching them to those in the 3D city map. There are different factors affecting the recognition process such as changes in the appearances of buildings, weather, and illumination conditions. The current aim was to study the salience of different types of visual cues in the r...

As an accountant and economist I once believed it is natural to guide business operations with management accounting information. I held to that belief until about ten years ago when I began to doubt the efficacy of using targets, scorecards, and other forms of quantitative data to guide, assess, and control operating activities. In this talk I describe briefly the journey that led me to doubt ...

This study was designed to examine EFL student writers majoring in English as a foreign language at university level in Iran to describe their vocabulary related problems and the strategies they used to overcome these problems. Thirty EFL students were given a writing task for think-aloud composing. The resulting protocols were coded and analysed. The data were examined in relation to vocabular...

Models of self-regulated learning (SRL) describe the complex and dynamic interplay of learners’ cognitions, motivations, and behaviors when engaged in a learning activity. Recently, researchers have begun to use fine-grained behavioral data such as think aloud protocols and logfile data from educational software to test hypotheses regarding the cognitive and metacognitive processes underlying S...

In the study of random processes, dependence is the rule rather than the exception. To facilitate the related statistical analysis, it is necessary to quantify the dependence between observations. In the talk I will briefly review the history of this fundamental problem. By interpreting random processes as physical systems, I will introduce physical and predictive dependence coefficients that q...

In this study we examined the effectiveness of self-regulated learning (SRL) training in facilitating college students’ science learning with hypermedia. Sixty (N = 60) undergraduate students were randomly assigned to either a training condition or a control condition and used a hypermedia environment to learn about the circulatory system. On Day 1, all participants were administered a pretest ...

[Note: These pages were my rough private notes that I made in preparation for the talk I gave. Needless to say, I didn’t cover all this material in my talk. I am willing, but hesitant, to put it on the web because of three reasons, the primary one being that I haven’t yet put in proper references for any of the results cited. The second reason is that in its next draft I will be separating much...

The development of algebraic topology in the twentieth century is one of the most important advances of its time. However, how did this development get under way? What forces worked to advance the subject, and perhaps more interestingly, to retard the development in its early days? In this talk I will present some historical approaches to these questions and the answers they produce. Toutes les...
