Tabu Search to Plan Schedules in a Multiskill Customer Contact Center

2006

International audience; We have studied a realistic case of scheduling problem in a customer contact center, dealing with multiskill agents. Our model combines the last two steps of the standard approach by determining shifts and by assigning them to agents at the same time (scheduling and rostering). Moreover, we have considered realistic vacations, according to legal constraints and preferences of agents. We have envisioned entire weeks of work, with variable meal times and meal durations, without overtime. In this paper, we define the problem and describe a Tabu search based solution.

A soldier’s occupational physical task requirements are diverse and varied. However, the type of physical training that most effectively improves soldiers’ occupational task requirements has not been studied previously. The purpose of this study was to determine the important strength characteristics for soldiers during a repeated simulated military task course, and the type of training that may be effective to improve these abilities during a specialized military training period. Forty-two (n = 42) soldiers participated in the study. They were divided into three training groups; a soldier task-specific training group (TSG, n = 17), a strength training group (STG, n = 15), and a control gro…

Serious Game Design for Flooding Triggered by Extreme Weather

2017

Managing crises with limited resources through a serious game is deemed as one of the ways of training and can be regarded as an alternative to a table-top exercise. This article presents the so-called “Operasjon Tyrsdal” serious game, inspired by a real case of extreme weather that hit the west coast of Norway. This reference case is used to add realism to the game. The game is designed for a single player, while the mechanics are framed in such a way that the player will have limited resources, and elevated event pressure over time. Beside applying an iterative Scrum method with seven Sprint cycles, we combined the development work with desk research and used the involvement of testers, i…

Comparing Freedom House Democracy Scores to Alternative Indices and Testing for Political Bias: Are US Allies Rated as More Democratic by Freedom Hou…

2014

AbstractSeveral scholars have criticized the Freedom House democracy ratings as being politically biased. Do countries indeed incorrectly receive better ratings that have stronger political ties with the United States? This article tests whether differences between a number of alternative indices of democracy and the FH ratings can be explained in a systematic manner by variables that record relationships between the US and the countries under investigation. Differentiating between the periods before 1988 and after 1989, strong and consistent evidence of a substantial bias in the FH ratings is obtained for the former period. For the latter period, the estimates are less consistent, but stil…

A VR-based serious game to regulate joy in adolescents: A comparison of different devices

2016

Adolescence is a crucial period to learn Emotional Regulation (ER) strategies to prevent future psychological problems. This work is aimed to test the efficacy of GameTeen System (GT-System), a serious game that teaches ER strategies to regulate joy (VAS scale) and perceived arousal (FAS scale) in a non-clinical sample of adolescents. We conducted a between-participants experiment in which participants (N = 63) played a joy induction game, and then an ER game using one of three types of devices (computer, smartphone, and RGB-D camera). Results revealed that GT-System was only effective in increase perceived arousal after the joy induction game and decrease after the ER game. Statistically s…

Design and validation of a tennis tool to control on-court technical and tactical training content

2021

In high performance tennis, different aspects like physical-conditioning, strategy-tactic, technical-biomechanical, psychology and skills acquisition have received large attention from the researchers. Nevertheless, the programming, periodization and planning of training sessions and competitions have not been as studied in depth. Coaches still use their experience, trial-error and subjective perceptions as methods of conducting these fundamental tasks. This article presents the design and validation of an instrument to control the technical and tactical training content on-court. The instrument was conceived by 9 experts and validated by 23 experienced coaches, who used on-court tennis ex…

Cytoplasmic incompatibility between Old and New World populations of a tramp ant

2020

Reproductive manipulation by endosymbiotic Wolbachia can cause unequal inheritance, allowing the manipulator to spread and potentially impacting evolutionary dynamics in infected hosts. Tramp and invasive species are excellent models to study the dynamics of host-Wolbachia associations because introduced populations often diverge in their microbiomes after colonizing new habitats, resulting in infection polymorphisms between native and introduced populations. Ants are the most abundant group of insects on earth, and numerous ant species are classified as highly invasive. However, little is known about the role of Wolbachia in these ecologically dominant insects. Here, we provide the first d…

Predicción del estado nutricional a través de la calidad de vida y el patrón del sueño en ancianos con deterioro cognitivo

2019

Resumen Objetivo: establecer y analizar una posible relación entre el estado nutricional, el patrón de sueño y la calidad de vida en una muestra de pacientes con disfunción cognitiva. Participantes y método: estudio observacional y descriptivo de un grupo de casos con una muestra constituida por 48 personas mayores (65 años o más) que aceptaron participar en el estudio y vivían en Valencia (España). EuroQol (EQ-5D), Cuestionario de Oviedo del sueño (COS), Mini Mental State de Folsteisn (MMSE) y Mini Nutritional Assessment (MNA) se utilizaron para evaluar el caso de cada individuo. La asociación de variables se evaluó mediante la correlación entre las tres variables. Finalmente, para verific…
