Different proposals have been made in recent years to exploit Social Web tagging data to improve recommender systems. The tagging data was used for example to identify similar users or viewed as additional information about the recommendable items. In this work we propose to use tags as a means to express which features of an item users particularly like or dislike. Users would therefore not on...

Most human figure models used in ergonomic analyses present postural comfort ratings based on joint angles, and present a single comfort score for the whole body or on a joint-by-joint basis. The source data for these ratings is generally derived from laboratory studies that link posture to ratings. Lacking in many of these models is a thorough treatment of the distribution of ratings for the p...

Hierarchical Cellular Networks (HCN) offer more efficient channel utilization and better quality of service (QoS) under the high tele-traffic condition compared to the single-tier system. One of the important measures of QoS in HCN as in any single-tier system is the handoff dropping rate. Although the existing approaches such as guard channel and queuing can reduce forced termination probabili...

Purpose: Radial head resection and open reduction and internal fixation (ORIF) are the traditional techniques for the treatment of radial head fractures (RHFs). The existing literature has not identified which is superior. We performed a meta-analysis of the current literature on excision and ORIF for RHFs to reach a relatively conclusive answer. Methods: A search was performed in PubMed, OVID,...

Résumé : Le but de ce travail est de faciliter l’interprétation d’une classification pyramidale construite sur un tableau de données symboliques. Alors que dans une hiérarchie binaire le nombre de paliers est égal à n-1, si n est le nombre d’individus à classer, dans le cas d’une pyramide ce dernier peut atteindre n(n-1)/2. Afin de réduire ce nombre, on élague la pyramide et on utilise un critè...

Abstract This paper is positioned at the interface of second/foreign language (L2) assessment and Conversation Analysis-Second Language Acquisition (CA-SLA). It explores challenges ratability in assessing interactional competence (IC) from three dimensions: an overview conceptual terminological convergence/divergence CA-SLA L2 literature, a micro-analytic Analysis test-taker interactions, opera...

The returns and risks of high-yield bond (HYB) lie between the stocks and Treasury bonds. In view of investment opportunities and the rate of return, the advantages of HYB are both lower risks and higher shares. Therefore, HYB has become one of important components in the portfolios. The purpose of this study is to identify critical factors related to the selection of HYB. Primary criteria to e...
