The VINEYARD Approach: Versatile, Integrated, Accelerator-Based, Heterogeneous Data Centres.

Emerging web applications like cloud computing, Big Data and social networks have created the need for powerful centres hosting hundreds of thousands of servers. Currently, the data centres are based on general purpose processors that provide high flexibility buts lack the energy efficiency of customized accelerators. VINEYARD aims to develop an integrated platform for energy-efficient data centres based on new servers with novel, coarse-grain and fine-grain, programmable hardware accelerators. It will, also, build a high-level programming framework for allowing end-users to seamlessly utilize these accelerators in heterogeneous computing systems by employing typical data-centre programming frameworks (e.g. MapReduce, Storm, Spark, etc.). This programming framework will, further, allow the hardware accelerators to be swapped in and out of the heterogeneous infrastructure so as to offer high flexibility and energy efficiency. VINEYARD will foster the expansion of the soft-IP core industry, currently limited in the embedded systems, to the data-centre market. VINEYARD plans to demonstrate the advantages of its approach in three real use-cases (a) a bio-informatics application for high-accuracy brain modeling, (b) two critical financial applications, and (c) a big-data analysis application.

Feasibility of Undertaking Off-Site Infant Eye-Tracking Assessments of Neuro-Cognitive Functioning in Early-Intervention Centres

Recent work suggests that differences in functional brain development are already identifiable in 6- to 9-month-old infants from low socio-economic status (SES) backgrounds. Investigation of early SES-related differences in neuro-cognitive functioning requires the recruitment of large and diverse samples of infants, yet it is often difficult to persuade low-SES parents to come to a university setting. One solution is to recruit infants through early intervention children’s centres (CCs). These are often located in areas of high relative deprivation to support young children. Given the increasing portability of eye-tracking equipment, assessment of large clusters of infants could be undertaken in centres by suitably trained early intervention staff. Here, we report on a study involving 174 infants and their parents, carried out in partnership with CCs, exploring the feasibility of this approach. We report the processes of setting up the project and participant recruitment. We report the diversity of sample obtained on the engagement of CC staff in training and the process of assessment itself.We report the quality of the data obtained, and the levels of engagement of parents and infants. We conclude that this approach has great potential for recruiting large and diverse samples worldwide, provides sufficiently reliable data and is engaging to staff, parents and infants.

Efficacité relative des grilles de correction d’un test de jugement situationnel pour la sélection du personnel de centres d’appels

Dans le domaine des centres d’appels, l’affectation d’agents au service à la clientèle efficaces et satisfaits représente une activité cruciale pour toute direction dédiée aux ressources humaines de ces unités d’affaires. Or, pour parvenir à prendre de bonnes décisions d’embauche et de rejet, des instruments de mesure et d’évaluation des compétences sont souvent mis à contribution. À cet effet, les tests de jugement situationnel (TJS) sont de plus en plus utilisés pour la sélection du personnel. L’objet de cette thèse est donc de vérifier l’efficacité relative des différentes méthodes d’élaboration des grilles de correction des TJS. En effet, jusqu’à présent, trois méthodes ont été privilégiées par les concepteurs de tests (Weekley, Ployhart, & Holtz, 2006) : (1) l’approche rationnelle ou théorique (2) l’approche empirique et (3) le recours à des experts. La possibilité qu’une combinaison de ces différentes approches puisse conduire à de meilleurs résultats est également explorée. Pour y parvenir, le résultat total obtenu à un TJS a été mis en lien avec une évaluation du rendement global effectuée par un supérieur immédiat en y appliquant huit grilles de correction différentes. Au total, un échantillon de 312 employés œuvrant dans des emplois de téléopérateurs au sein d’une grande institution financière québécoise ont participé à cette recherche. Dans l’ensemble, les résultats indiquent qu’une approche empirique permet généralement d’obtenir de meilleures statistiques descriptives en termes de distribution et de dispersion des scores pour un processus de sélection. Cependant, des analyses corrélationnelles indiquent qu’une approche multiple ou méthode hybride, basée sur une intégration des informations fournies par différentes sources d’informations (empirique, théorique et basé sur les experts) pour l’élaboration d’une grille de correction d’un TJS, permet de mieux prédire le rendement des employés (r=0,247**) comparativement à l’utilisation de la théorie pour définir les attentes (r=0,162**), le recours à des experts de contenu œuvrant dans le domaine de pratique (r=0,164**) ou l’utilisation d’une approche empirique (r=0,154*). Mots clés : Test de jugement situationnel, grilles de correction, validité critériée, centre d’appels.

Replicating the Networking, Mentoring and Venture Creation Benefits of Entrepreneurship Centres on a Shoestring: A Student-centred Approach to Entrepreneurship Education and Venture Creation

As support for both university-level entrepreneurial education and the use of experiential learning methods to foster student entrepreneurs increases, so too have the number of university-established or affiliated entrepreneurship centers. The activity at the center of this study aimed to combine experiential learning methods with assets associated with entrepreneurship centers, including venture creation, networking, and mentoring. Students were invited to participate in a competition wherein they were guided through the business creation process and pitched their ideas to investor judges who chose the winner and provided capital start-up funding and consulting. This research puts forth that university faculty at institutions without entrepreneurship centers can organize experiences to provide the benefits of entrepreneurship centers. The study used interviews to find that many of the benefits of entrepreneurship centers were able to be replicated using this method. The project is outlined, outcomes are analyzed, and the results and lessons learned are discussed.

Evaluating the potential for urban consolidation centres

This paper focuses upon the potential for Urban Consolidation Centres (UCCs) to alleviate local environmental and traffic problems within urban areas. An international literature review was undertaken, interviews were held with a range of relevant parties, and an evaluation framework was developed. In previous work a narrow focus has typically been adopted and no examples of thorough scheme evaluation were found. A particular concern discussed in the paper is the identification and subsequent allocation of the costs and benefits of implementing and operating a UCC. Lessons learned from existing and attempted UCCs are then presented, and a number of themes and location types that point to successful implementation are identified. The likelihood of a UCC being successful depends considerably upon the legal and planning frameworks in the locality or country involved.
