Innovative data collection methods in criminological research: editorial introduction

Novel technologies, such as GPS, the Internet and virtual environments are not only rapidly becoming an increasingly influential part of our daily lives, they also have tremendous potential for improving our understanding of where, when and why crime occurs. In addition to these technologies, several innovative research methods, such as neuropsychological measurements and time-space budgets, ha...

Issues Related to Data Analysis and Quantitative Methods in PER

On the very same quiz, Question #8 asks the students to choose a vector diagram that most closely represents the gravitational forces that the earth and moon exert on each other. The three most popular choices are shown in the figure below. There are a number of issues that always arise, implicitly or explicitly, when conducting quantitative research and carrying out data analysis in Physics Ed...

Collection-focused Parallelism

Constructing parallel software is, in essence, the process of associating ‘work’ with computational units. The definition of work is dependent upon the model of parallelism used, and our choice of model can have profound effects on both programmer productivity and run-time efficiency. Given that the movement of data is responsible for the majority of parallelism overhead, and accessing data is ...

Investigating Model Behavioural Analysis: A Critical Examination of Two Methods

Two methods for model behavioural analysis are implemented on a simple 2 order nonlinear model. The results of applying Ford’s behavioral approach are compared with those obtained using both system-wide and variable-specific loop eigenvalue elasticity analysis. Differences in the division of the time span into analysis intervals are identified as are discrepancies in the outcomes. The effort re...
