This paper reports on an empirical study that investigates the effects of the personality trait of neuroticism on the academic performance of students who practiced pair programming during one academic semester. The experiment was conducted at The University of Auckland involving 270 first year undergraduate students enrolled in an introductory programming course. In this study, we hypothesized that neuroticism or lack of 'emotional stability' potentially affects pair students' academic performance. However, from the analysis of our results we found lack of evidence to support this. A correlation analysis showed significant positive associations between the conscientiousness personality trait and almost all performance criteria, thus corroborating evidence reported in the educational psychology literature. © 2010 ACM.

International Conference on Frontiers in Handwriting Recognition

Arbitrary orientation and sparse data content are common characteristics of torn document. To ensure accuracy and reliability in computer-based analysis, content-zone segmentation is required. In our previous work, we studied segmentation of handwritten and printed text. A questioned document-piece in the form of an office note, however, might also contain non-text data like logos, graphics, and pictures. Hence a more precise content-zone classification is required. In this paper we propose a two-Tier approach for non-text, handwriting and printed text segmentation. The first Tier aims to discriminate text and non-text regions. The second Tier classifies handwritten and printed text within all text zones identified during the first Tier. Gabor features and chain-code features are used in Tier-1 and Tier-2, respectively. By using SVM classifier we successfully identified 97.65% of 31,227 text regions in our current test data. The proposed approach identified 98.69% of printed and 96.39% of handwritten text amongst all identified text regions. © 2010 IEEE.

This position paper describes the Human-computer Interaction (HCI) field studies component of the multidisciplinary Patient Records Enhancement Project (PREP). PREP seeks to understand variability of data found in primary care electronic records, in particular the balance between coded data and doctor's 'free text' notes. HCI fieldwork will establish variables that affect recording practices. In field studies we observe and record data recording practices in general practice (GP) surgeries, interview staff, video consultations with real patients and video consultations with standardized patients (played by medical actors). By standardizing patients we can compare the impact of other variables: different doctors, in different surgeries, using different e-health systems. Our early findings suggest that variability is due to a complex web of reasons, driven by personal, contextual and organizational processes. Findings from thematic analysis will result in design implications for studies by epidemiologists and public health researchers, design of NHS training and work processes, and design of electronic health record interfaces. © 2011 ICST.

The need of interoperable e-government services is addressed through the use of web services where sensitive services need to be granted to only authorized subjects from different organizations. In this paper, we propose a Trust and Dynamic Role Based Access Control model (TDRBAC) which deals with the specific requirements of e-government services. It effectively enhances the access control level since it is based on the trust level notion. The trust level evaluation is based on contextual attributes to assign to user role the appropriate view during the active session. The TDRBAC model is sensitive to the internal or external arisen events and it incorporates them in the access decision which makes it suitable for e-government dynamic environment. © 2010 IEEE.

This paper presents a semi-automatic method for the visualization and analysis of motion in signed language from a digital video. The method detects the different parts of the signer's bare skin on the video, tracks the motion of the different parts of the body and represents the frame-wise motion of the parts of the body with statistical descriptors. Results of an experiment are demonstrated and discussed. The main linguistic issue deals with the relationship between signs and transitional sequences. Evidence is provided for the claim that lexical-phonological and transitional sequences are qualitatively different in terms of their motion characteristics. © 2010 Proceedings of the International Conference on Speech Prosody.

Automatic identification of an individual based on his/her handwriting characteristics is an important forensic tool. In a computational forensic scenario, presence of huge amount of text/information in a questioned document cannot be always ensured. Also, compromising in terms of systems reliability under such situation is not desirable. We here propose a system to encounter such adverse situation in the context of Bengali script. Experiments with discrete directional feature and gradient feature are reported here, along with Support Vector Machine (SVM) as classifier. We got promising results of 95.19% writer identification accuracy at first top choice and 99.03% when considering first three top choices. © 2010 IEEE.

Gene regulation is controlled by transcription factor proteins which themselves are encoded as genes. This gives a network of interacting genes which control the functioning of a cell. With the advent of genome wide expression measurements the targets of given transcription factor have been sought through techniques such as clustering. In this paper we consider the harder problem of finding a gene's regulator instead of its targets. We use a model-based differential equation approach combined with a Gaussian process prior distribution for unobserved continuous-time regulator expression profile. Candidate regulators can then be ranked according to model likelihood. This idea, that we refer to as ranked regulator prediction (RRP), is then applied to finding the regulators of Gata3, an important developmental transcription factor, in the development of ear hair cells. ©2010 IEEE.

We present the information extraction system Text2SemRel. The system (semi-) automatically constructs knowledge bases from textual data consisting of facts about entities using semantic relations. An integral part of the system is a graph-based interactive visualization and search layer. The second contribution in this paper is the presentation of a case study on the (semi-)automatic construction of a knowledge base consisting of gene-disease associations. The resulting knowledge base, the Literature-derived Human Gene-Disease Network (LHGDN), is now an integral part of the Linked Life Data initiative and represents currently the largest publicly available gene-disease repository. The LHGDN is compared against several curated state of the art databases. A unique feature of the LHGDN is that the semantics of the associations constitute a wide variety of biomolecular conditions. © 2010 ACM.

Because of restricted energy of the sensor nodes, the location error, costs of communication and computation should be considered in localization algorithms. The DV-Hop algorithm was detailedly analyzed and the main reasons for the error were pointed out, aiming at the different position anchor nodes' effect on location error, a novel localization algorithm called DV-Hop_Bon (DV-Hop based on optimal nodes) based on optimal nodes was put forward. Finally, it was simulated on Matlab, the results of the simulation show that the novel localization algorithm improves the localization precision with a short communication radius. Therefore it can be applied to wireless sensor networks widely.
