BACKGROUND Pedestrian crossing is an important traffic safety concern. The aim of this paper is to report the protocol for a sequential explanatory mixed methods study that set out to determine the pedestrians' traffic behaviors, the associated factors and exploring the perception of young people about the traffic risky behaviors in crossing the road. The ultimate purpose of the study is to des...

We have developed models of how strategies are constructed and retained as male and female high school and university students gain experience in solving online qualitative chemical analysis problems. The most common strategies that students used when solving online problem-solving simulations were first classified using self-organizing artificial neural networks. This resulted in strategy maps...

The naturalness of qualitative reasoning suggests that qualitative representations might be an important component of the semantics of natural language. Prior work showed that framebased representations of qualitative process theory constructs could indeed be extracted from natural language texts. That technique relied on the parser recognizing specific syntactic constructions, which had limite...

In this work, we analyzed the impact of interventions on populations which exhibit unimodal dynamics. The six landmarks that characterize the “shape” of the unimodal reproduction curve   f x of the difference equation,   1 n n X f X   , are defined and used in order to examine and determine the behavior of dynamics of populations. By using the Li-Yorke criterion for determination of chaos...

This paper proposes an integrated framework for analysis of an electricity supply chain using an integrated SWOT-fuzzy TOPSIS methodology combined with Analytic Hierarchy Process (AHP). The paper is divided into twomain sections. In the firstmain section, the integrated framework comprising a qualitative framework and a quantitative framework is presented. In the qualitative framework, a genera...

The main purpose of this qualitative research was designing an export marketing strategy model for tea product to the target markets. The statistical population was composed of all experts in the field of this research topic (N = 332), the sample size was determined as the same as the statistical population. Second-hand data used for collecting data and a semi-structured interview was used as a...

Controlling a complex dynamic system, such as a plane or a crane, usually requires a skilled operator . Such a control skill is typically hard to reconstruct through introspection . Therefore an attractive approach to the reconstruction of control skill involves machine learning from operators' control traces, also known as behavioural cloning . In the most common approach to behavioural clonin...
