Étude exploratoire des obstacles à la transition universitaire selon le vécu d’étudiants français et belges

2020

International audience; Transition to Higher Education constitutes a challenging adjustment step for students that deserves major investigation. Yet, the transition obstacles are still overlooked. Most of international studies focused on individual predictors of adjustment and consider transition to Higher Education as a universal and invariant process. However, contextual characteristics of educational environment should be considered because they don’t imply the same requirements for adjustment. In order to address this limitation, this paper realized an exploratory comparison of first year student experience between a French and a Belgian university. The results highlighted similarities …

Downstream Intra-organizational Product Market Competition Between Employees: A Theoretical Approach

2020

To investigate the downstream internal competition and its effect on firm’s performance comprehensive literature review has been conducted. The concentration is on recognized social dimensions, similar focus is on communications, interactions and interrelationship between departments and business units. The Integration of intra-organizational competition and internal social comparison balances the literature review. Although it is quite controversial to practice and encourage internal competition having it’s sustained effect on behavioral of employees. The basis of literature review relies on human tendency to compare and coordinate work activities inside firm’s boundaries. The literature e…

Nonlinear Nonhomogeneous Robin Problems with Almost Critical and Partially Concave Reaction

2020

We consider a nonlinear Robin problem driven by a nonhomogeneous differential operator, with reaction which exhibits the competition of two Caratheodory terms. One is parametric, $$(p-1)$$-sublinear with a partially concave nonlinearity near zero. The other is $$(p-1)$$-superlinear and has almost critical growth. Exploiting the special geometry of the problem, we prove a bifurcation-type result, describing the changes in the set of positive solutions as the parameter $$\lambda >0$$ varies.

Effect of intra-organisational competition on organisational performance indicators

2021

The objective of the research is to investigate intra-organisational competition (IOC) emerging from the interactions of internal social comparison (ISC) and intra-organisational evolution (IOE) effecting organisational performance (OP). Communication between subordinates, comparing contribution, ability to perform and business management strategies resulting in IOC. The attention is on recognised social dimensions and equal emphasis is on business management practices. The literature attempts’ to recognise ISC and IOE and its effect on OP balances the conceptual paper. For the purpose Google Scholar, Emerald Insight, EBSCO Host and Science Direct database has been used. Literature relies o…

Performance comparison of container orchestration platforms with low cost devices in the fog, assisting Internet of Things applications

2020

Abstract In the last decade there has been an increasing interest and demand on the Internet of Things (IoT) and its applications. But, when a high level of computing and/or real time processing is required for these applications, different problems arise due to their requirements. In this context, low cost autonomous and distributed Small Board Computers (SBC) devices, with processing, storage capabilities and wireless communications can assist these IoT networks. Usually, these SBC devices run an operating system based on Linux. In this scenario, container-based technologies and fog computing are an interesting approach and both have led to a new paradigm in how devices cooperate, improvi…

Ranking-Oriented Collaborative Filtering: A Listwise Approach

2016

Collaborative filtering (CF) is one of the most effective techniques in recommender systems, which can be either rating oriented or ranking oriented. Ranking-oriented CF algorithms demonstrated significant performance gains in terms of ranking accuracy, being able to estimate a precise preference ranking of items for each user rather than the absolute ratings (as rating-oriented CF algorithms do). Conventional memory-based ranking-oriented CF can be referred to as pairwise algorithms. They represent each user as a set of preferences on each pair of items for similarity calculations and predictions. In this study, we propose ListCF, a novel listwise CF paradigm that seeks improvement in bot…

On the Computation of Symmetrized M-Estimators of Scatter

2016

This paper focuses on the computational aspects of symmetrized Mestimators of scatter, i.e. the multivariate M-estimators of scatter computed on the pairwise differences of the data. Such estimators do not require a location estimate, and more importantly, they possess the important block and joint independence properties. These properties are needed, for example, when solving the independent component analysis problem. Classical and recently developed algorithms for computing the M-estimators and the symmetrized M-estimators are discussed. The effect of parallelization is considered as well as new computational approach based on using only a subset of pairwise differences. Efficiencies and…

Concurrent Molecular Dynamics Simulation of ST2 Water on a Transputer Array

1988

Abstract A concurrent implementation of a Molecular Dynamics program for ST2 water molecules is presented, which exploits the great potentialities of the Transputer arrays for statistical mechanical calculations. High load-balance efficiency is obtained using a new task decomposition algorithm which evenly distributes particles and interaction calculations among the processors. This approach can also help to solve efficiently the more general problem of task distribution in parallel computing of symmetric pairwise system properties.

Performance Comparison of Duobinary Modulation Formats for 40 Gb/s Long-Haul WDM Transmissions

2006

With their compact spectrum and high tolerance to residual chromatic dispersion, duobinary formats are attractive for the deployment of 40 Gb/s technology on 10 Gb/s WDM Long-Haul transmission infrastructures. Here, we compare the robustness of various duobinary formats when facing 40 Gb/s transmission impairments.
