Abstract Concept mapping has been widely adopted in the past few decades as an instructional or learning tool for helping students organize their knowledge; nevertheless, several previous studies have indicated the difficulty of applying this approach. In particular, for elementary school students, developing concept maps could be a difficult task, implying the importance of providing supports during the learning process. In this study, a computerized, cooperative concept-mapping approach ...

eal-life problems it is convenient to reduce the number of involved features (variables) in order to reduce the complexity, especially when the number of features is large compared to the number of observations. There are several criteria to tackle this variable reduction problem. Three of the most common are: maximization of the mutual information (MI) between the inputs and the outputs, minimization of the k-nearest neighbors (k-NN) leave-one-out generalization error estimate and minimiz...

(1980)), Systenfie Fmmtional Grammar (SFO; (Halliday, 19671 Halliday, 1970)). The goal of this comparison is the definition of a mapping between the two systems. This attempt ha...

T metric electrical data which can then be used to evaluate the performance of an integrated circuit manufacturing process. The test chips contain test structures which provide specific electrical parameters. Coupled with a computer-controlled parametric test system, they can provide the user with information that cannot otherwise be obtained because of the nature of the measurement, the measurement time, or the cost associated with other methods of performing the measurement. Comp...

The promise of personalized medicine has been touted for many years but has been elusive in some specialties.1 Recently, with the influx of large data sets from “omics”- based methods including genomics, transcriptomics, and metabolomics, personalized approaches to medical practice have come to the forefront and many specialties now use some form of personalized medicine in research and clinical care. This is particularly true in oncology where biomarker-guided treatme...

1. INTRODUCTION The Intelligent Vehicle/ Highway Systems (IVHS) program is a major initiative of government, industry, and academia to apply advanced technology to the operation of the Nation’s surface transportation systems in order to improve mobility, transportation productivity, enhance safety, maximize the use of existing transportation facilities, conserve energy resources, and reduce adverse environmental effects. The IVHS program consists of the following five broad, interrelated ...

1. INTRODUCTION An aspect-oriented program typically consists of a number of modules (or classes) and aspects that can be woven into an executable whole [1][2][3]. The crosscutting mechanism of aspects frees the programmer from interweaving different concerns (i.e. goals, concepts, or areas of interests) in a monotonous program hierarchy imposed by the base language. This greatly facilitates identifying and modularizing separate concerns that crosscut multiple functional componen...

Owing to the advance and popularity of computer and network technologies, computer technology-enhanced learning has attracted the attention of researchers in recent years (Ge & Land, 2004; Liaw, Huang & Chen, 2007; Williams van Rooij, 2009). Although several studies have demonstrated the benefits of learning with computers (eg, Pena-Shaffa & Nichollsb, 2004; Tsai & Tsai, 2003), educators have emphasised the importance and necessity of ‘authentic activities’ in which students can work wi...

Social studies for elementary schools is an interdisciplinary subject which needs to integrate different learning domains of theories and principles so that students can apply them in their daily life. In traditional instruction, most teachers tend to instruct via lectures, and hence students seldom have the chance to organize the learning content and link what they have learned with their daily life experience. In this case, it is likely that only the cognitive objectives at a low level...

The repeated occurrence of turmoils in international financial markets has drawn a striking interest in the linkages between financial markets during times of crisis. Indeed, in turbulent periods we observe an increase in cross-market linkages due to the propagation of shocks from one country to other countries as a consequence of the high integration of financial and goods markets. The increase in cross-market linkages from the pre-crisis period to the crisis period may take the form of int...
