Distributed $n$-player approachability and consensus in coalitional games
2015
We study a distributed allocation process where, at each time, every player: i) proposes a new bid based on the average utilities produced up to that time, ii) adjusts such allocations based on the inputs received from its neighbors, and iii) generates and allocates new utilities. The average allocations evolve according to a doubly (over time and space) averaging algorithm. We study conditions under which the average allocations reach consensus to any point within a predefined target set even in the presence of adversarial disturbances. Motivations arise in the context of coalitional games with transferable utilities (TU) where the target set is any set of allocations that makes the grand …
Multi-objective human resources allocation in R&D projects planning
2009
In a R&D department, several projects may have to be implemented simultaneously within a certain period of time by a limited number of human resources with diverse skills. This paper proposes an optimisation model for the allocation of multi-skilled human resources to R&D projects, considering individual workers as entities having different knowledge, experience and ability. The model focuses on three fundamental aspects of human resources: the different skill levels, the learning process and the social relationships existing in working teams. The resolution approach for the multi-objective problem consists of two steps: firstly, a set of non-dominated solutions is obtained by exploring the…
Les organisations publiques : des institutions communicantes ? Le cas des Caisses d'Allocations Familiales
2009
L’objectif de cet article est de proposer une approche comprehensive de la communication des organisations publiques a travers le cas des Caisses d’Allocations Familiales (CAF). Les travaux dont il est issu ont eu pour objet d’interroger les representations des cadres, charges de communication et directeurs des CAF autour de la notion d’institution communicante. Il s’agit notamment de preciser si celle-ci releve d’un artefact ou pourrait -et a quelles conditions- constituer un modele valide pour analyser la communication des organisations publiques.
Privatisation, gouvernement d'entreprise et processus décisionnel:une interprétation de la dynamique organisationnelle à travers le cas France Télécom
2001
This article tries to explain the influence of privatization on the decision making process, especially in terms of investments through the corporate governance theory. In this perspective we suggest a conceptual framework based on the analysis of disciplinary mechanisms and their dynamic as a foundation of an explanatory research applied to the France Télécom case.
Studying principals' resource allocation and affecting resource factors for physical education in Finland
2013
The aims of the present study were to investigate principals’ opinions of PE resourcing in schools. Resourcing was divided for different resourcing factors in schools: principals’ money allocation, qualified PE teachers, PE teachers’ in-service education, extracurricular PE and optional PE courses. These resource factors were investigated by associations between school size and different resourcing factors and between school’s regional location and different resourcing factors. Other aims were to study if principals’ and PE teachers’ opinions of PE resourcing diverge and to compare results of PE resourcing to previous PE evaluations study (Huisman 2004) in 2003. A follow-up evaluation 2010 …

Data from: Age-related effects of chronic hantavirus infection on female host fecundity
2016
1. Pathogens often cause detrimental effects to their hosts and, consequently, may influence host population dynamics that may, in turn, feed back to pathogen transmission dynamics. Understanding fitness effects of pathogens upon animal host populations can help to predict the risks that zoonotic pathogens pose to humans. 2. Here we determine whether chronic infection by Puumala hantavirus (PUUV) affects important fitness-related traits, namely the probability of breeding, reproductive effort and mother and offspring condition, in the bank vole (Myodes glareolus). Using 9 years empirical data in a PUUV endemic area in Central Finland, we found differences between reproductive characteristic…
Data from: No inbreeding depression but increased sexual investment in highly inbred ant colonies
2012
Inbreeding can lead to the expression of deleterious recessive alleles and to a subsequent fitness reduction. In Hymenoptera, deleterious alleles are purged in haploid males moderating inbreeding costs. However, in these haplo-diploid species, inbreeding can result in the production of sterile diploid males. We investigated the effects of inbreeding on the individual and colony level in field colonies of the highly inbred ant Hypoponera opacior. In this species, outbreeding winged sexuals and nest-mating wingless sexuals mate during two separate reproductive periods. We show that regular sib-matings lead to high levels of homozygosity and the occasional production of diploid males, which sp…
Screw fixation of radial head fractures: Compression screw versus lag screw—A biomechanical comparison
2009
Abstract Introduction Secondary loss of reduction and pseudarthrosis due to unstable fixation methods remain challenging problems of surgical stabilisation of radial head fractures. The purpose of our study was to determine whether the 3.0 mm Headless Compression Screw (HCS) provides superior stability to the standard 2.0 mm cortical screw (COS). Materials and methods Eight pairs of fresh frozen human cadaveric proximal radii were used for this paired comparison. A standardised Mason II-Fracture was created with a fragment size of 1/3 of the radial head's articular surface that was then stabilised either with two 3.0 mm HCS (Synthes) or two 2.0 mm COS (Synthes) according to a randomisation …
Rationing in a Pandemic: Lessons from Italy.
2020
In late February and early March 2020, Italy became the European epicenter of the COVID-19 pandemic. Despite increasingly stringent containment measures enforced by the government, the health system faced an enormous pressure, and extraordinary efforts were made in order to increase overall hospital beds’ availability and especially ICU capacity. Nevertheless, the hardest-hit hospitals in Northern Italy experienced a shortage of ICU beds and resources that led to hard allocating choices. At the beginning of March 2020, the Italian Society of Anesthesia, Analgesia, Resuscitation, and Intensive Care (SIAARTI) issued recommendations aimed at supporting physicians in prioritizing patients when …
