Relating emotional intelligence to academic achievement among university students in Barbados
This study investigated the relationships between emotional intelligence and academic
achievement among 151 undergraduate psychology students at The University of the
West Indies (UWI), Barbados, making use of Barchard (2001)’s Emotional Intelligence
Scale and an Academic Achievement Scale. Findings revealed significant positive
correlations between academic achievement and six of the emotional intelligence
components, and a negative correlation with negative expressivity. The emotional
intelligence components also jointly contributed 48% of the variance in academic
achievement. Attending to emotions was the best predictor of academic achievement
while positive expressivity, negative expressivity and empathic concern were other
significant predictors. Emotion-based decision-making, responsive joy and responsive
distress did not make any significant relative contribution to academic achievement,
indicating that academic achievement is only partially predicted by emotional
intelligence. These results were discussed in the context of the influence of emotional
intelligence on university students’ academic achievement.peer-reviewe
The role of trait emotional intelligence and social and emotional skills in students’ emotional and behavioural strengths and difficulties : a study of Greek adolescents’ perceptions
The emergence of the Trait Emotional Intelligence construct shifted the interest in
personality research to the investigation of the effect of global personality characteristics
on behaviour. A second body of research in applied settings, the Social and Emotional
Learning movement, emphasized the cultivation of emotional and social skills for
positive relationships in a school environment. In this paper we investigate the role of
both personality traits and social and emotional skills, in the occurrence of emotional and
behavioural strengths and difficulties, according to adolescent students’ self-perceptions.
Five hundred and fifty-nine students from state secondary schools in Greece, aged 12-14
years old, completed The Trait Emotional Intelligence Questionnaire-Adolescent Short
Form, The Matson Evaluation of Social Skills with Youngsters, and The Strengths and
Difficulties Questionnaire. It was found that students with higher Trait Emotional
Intelligence and stronger social and emotional skills were less likely to present
emotional, conduct, hyperactivity and peer difficulties and more likely to present
prosocial behaviour. Gender was a significant factor for emotional difficulties and grade
for peer difficulties. The paper describes the underlying mechanisms of students’
emotional and behavioural strengths and difficulties, and provides practical implications
for educators to improve the quality of students’ lives in schools.peer-reviewe
3D medical volume segmentation using hybrid multiresolution statistical approaches
This article is available through the Brunel Open Access Publishing Fund. Copyright © 2010 S AlZu’bi and A Amira.3D volume segmentation is the process of partitioning voxels into 3D regions (subvolumes) that represent meaningful physical entities which are more meaningful and easier to analyze and usable in future applications. Multiresolution Analysis (MRA) enables the preservation of an image according to certain levels of resolution or blurring. Because of multiresolution quality, wavelets have been deployed in image compression, denoising, and classification. This paper focuses on the implementation of efficient medical volume segmentation techniques. Multiresolution analysis including 3D wavelet and ridgelet has been used for feature extraction which can be modeled using Hidden Markov Models (HMMs) to segment the volume slices. A comparison study has been carried out to evaluate 2D and 3D techniques which reveals that 3D methodologies can accurately detect the Region Of Interest (ROI). Automatic segmentation has been achieved using HMMs where the ROI is detected accurately but suffers a long computation time for its calculations
A Tutorial on Bayesian Nonparametric Models
A key problem in statistical modeling is model selection, how to choose a
model at an appropriate level of complexity. This problem appears in many
settings, most prominently in choosing the number ofclusters in mixture models
or the number of factors in factor analysis. In this tutorial we describe
Bayesian nonparametric methods, a class of methods that side-steps this issue
by allowing the data to determine the complexity of the model. This tutorial is
a high-level introduction to Bayesian nonparametric methods and contains
several examples of their application.Comment: 28 pages, 8 figure
One-Class Classification: Taxonomy of Study and Review of Techniques
One-class classification (OCC) algorithms aim to build classification models
when the negative class is either absent, poorly sampled or not well defined.
This unique situation constrains the learning of efficient classifiers by
defining class boundary just with the knowledge of positive class. The OCC
problem has been considered and applied under many research themes, such as
outlier/novelty detection and concept learning. In this paper we present a
unified view of the general problem of OCC by presenting a taxonomy of study
for OCC problems, which is based on the availability of training data,
algorithms used and the application domains applied. We further delve into each
of the categories of the proposed taxonomy and present a comprehensive
literature review of the OCC algorithms, techniques and methodologies with a
focus on their significance, limitations and applications. We conclude our
paper by discussing some open research problems in the field of OCC and present
our vision for future research.Comment: 24 pages + 11 pages of references, 8 figure
Multi-layer Architecture For Storing Visual Data Based on WCF and Microsoft SQL Server Database
In this paper we present a novel architecture for storing visual data.
Effective storing, browsing and searching collections of images is one of the
most important challenges of computer science. The design of architecture for
storing such data requires a set of tools and frameworks such as SQL database
management systems and service-oriented frameworks. The proposed solution is
based on a multi-layer architecture, which allows to replace any component
without recompilation of other components. The approach contains five
components, i.e. Model, Base Engine, Concrete Engine, CBIR service and
Presentation. They were based on two well-known design patterns: Dependency
Injection and Inverse of Control. For experimental purposes we implemented the
SURF local interest point detector as a feature extractor and -means
clustering as indexer. The presented architecture is intended for content-based
retrieval systems simulation purposes as well as for real-world CBIR tasks.Comment: Accepted for the 14th International Conference on Artificial

Dimensions of Neural-symbolic Integration - A Structured Survey
Research on integrated neural-symbolic systems has made significant progress
in the recent past. In particular the understanding of ways to deal with
symbolic knowledge within connectionist systems (also called artificial neural
networks) has reached a critical mass which enables the community to strive for
applicable implementations and use cases. Recent work has covered a great
variety of logics used in artificial intelligence and provides a multitude of
techniques for dealing with them within the context of artificial neural
networks. We present a comprehensive survey of the field of neural-symbolic
integration, including a new classification of system according to their
architectures and abilities.Comment: 28 page
