Pour réussir dans la vie professionnelle, a-t-on besoin d'un bon quotient intellectuel (QI) ou d'un bon quotient émotionnel (QÉ)?

Après avoir présenté brièvement deux courants conceptuels à propos de l’intelligence émotionnelle (IÉ), nous abordons l’impact de celle-ci sur sept aspects du monde du travail : le leadership, la formation du personnel, la sélection du personnel, le rendement à la tâche, la gestion des conflits, les attitudes au travail et le bien-être au travail. Alors que l’intelligence émotionnelle promettait au départ de bouleverser le monde du travail, un grand nombre d’études montre que celle-ci ne fait pas le poids, particulièrement au plan de sa validité. Comparée à la valeur prédictive du quotient intellectuel (QI), l’intelligence émotionnelle montre un faible pouvoir prédicteur, en dépit des instruments judicieux que ses promoteurs ont mis au point pour mesurer ses effets.

Measurability characteristics mapping for large volume metrology instruments selection

Measurement and verification of products and processes during the early design is attracting increasing interest from high value manufacturing industries. Measurement planning is deemed as an effective means to facilitate the integration of the metrology activity into a wider range of production processes. However, the literature reveals that there are very few research efforts in this field, especially regarding large volume metrology. This paper presents a novel approach to accomplish instruments selection, the first stage of measurement planning process, by mapping measurability characteristics between specific measurement assignments and instruments.

A Search for a New Particle Decaying to Pairs of Weak Gauge Bosons with the ATLAS Detector

A search for new heavy resonances decaying to boson pairs (WZ, WW or ZZ) using 20.3 inverse femtobarns of proton-proton collision data at a center of mass energy of 8 TeV is presented. The data were recorded by the ATLAS detector at the Large Hadron Collider (LHC) in 2012. The analysis combines several search channels with the leptonic, semi-leptonic and fully hadronic final states. The diboson invariant mass spectrum is studied for local excesses above the Standard Model background prediction, and no significant excess is observed for the combined analysis. 95$\%$ confidence limits are set on the cross section times branching ratios for three signal models: an extended gauge model with a heavy W boson, a bulk Randall-Sundrum model with a spin-2 graviton, and a simplified model with a heavy vector triplet. Among the individual search channels, the fully-hadronic channel is predominantly presented where boson tagging technique and jet substructure cuts are used. Local excesses are found in the dijet mass distribution around 2 TeV, leading to a global significance of 2.5 standard deviations. This deviation from the Standard Model prediction results in many theory explanations, and the possibilities could be further explored using the LHC Run 2 data.

Weak coupling of acoustic-like phonons and magnon dynamics in incommensurate spin ladder compound Sr14Cu24O41

Intriguing lattice dynamics has been predicted for aperiodic crystals that contain incommensurate substructures. Here we report inelastic neutron scattering measurements of phonon and magnon dispersions in Sr14Cu24O41, which contains incommensurate one-dimensional (1D) chain and two-dimensional (2D) ladder substructures. Two distinct acoustic phonon-like modes, corresponding to the sliding motion of one sublattice against the other, are observed for atomic motions polarized along the incommensurate axis. In the long wavelength limit, it is found that the sliding mode shows a remarkably small energy gap of 1.7-1.9 meV, indicating very weak interactions between the two incommensurate sublattices. The measurements also reveal a gapped and steep linear magnon dispersion of the ladder sublattice. The high group velocity of this magnon branch and weak coupling with acoustic phonons can explain the large magnon thermal conductivity in Sr14Cu24O41 crystals. In addition, the magnon specific heat is determined from the measured total specific heat and phonon density of states, and exhibits a Schottky anomaly due to gapped magnon modes of the spin chains. These findings offer new insights into the phonon and magnon dynamics and thermal transport properties of incommensurate magnetic crystals that contain low-dimensional substructures.

'Lines of flight': digital musical instruments, inclusive music bands, meaningful engagement in music-making and learning

In this study I examine the development of three inclusive music bands in Cork city. Derived from Jellison’s research on inclusive music education, inclusive music bands involve students with disabilities coming together with typically developing peers to make and learn music that is meaningful (Jellison, 2012). As part of this study, I established three inclusive music bands to address the lack of inclusive music making and learning experiences in Cork city. Each of these bands evolved and adapted in order to be socio-culturally relevant within formal and informal settings: Circles (community education band), Till 4 (secondary school band) and Mish Mash (third level and community band). I integrated Digital Musical Instruments into the three bands, in order to ensure access to music making and learning for band members with profound physical disabilities. Digital Musical Instruments are electronic music devices that facilitate active music making with minimal movement. This is the first study in Ireland to examine the experiences of inclusive music making and learning using Digital Musical Instruments. I propose that the integration of Digital Musical Instruments into inclusive music bands has the potential to further the equality and social justice agenda in music education in Ireland. In this study, I employed qualitative research methodology, incorporating participatory action research methodology and case study design. In this thesis I reveal the experiences of being involved in an inclusive music band in Cork city. I particularly focus on examining whether the use of this technology enhances meaningful music making and learning experiences for members with disabilities within inclusive environments. To both inform and understand the person centered and adaptable nature of these inclusive bands, I draw theoretical insights from Sen’s Capabilities Approach and Deleuze and Guatarri’s Rhizome Theory. Supported by descriptive narrative from research participants and an indepth examination of literature, I discover the optimum conditions and associated challenges of inclusive music practice in Cork city.

Simulation of Distributed Contact in String Instruments: a Modal Expansion Approach

Impactive contact between a vibrating string and a barrier is a strongly nonlinear phenomenon that presents several challenges in the design of numerical models for simulation and sound synthesis of musical string instruments. These are addressed here by applying Hamiltonian methods to incorporate distributed contact forces into a modal framework for discrete-time simulation of the dynamics of a stiff, damped string. The resulting algorithms have spectral accuracy, are unconditionally stable, and require solving a multivariate nonlinear equation that is guaranteed to have a unique solution. Exemplifying results are presented and discussed in terms of accuracy, convergence, and spurious high-frequency oscillations.

Accessibility Instruments In Planning Practice: Bridging The Implementation Gap

Accessibility concepts are increasingly acknowledged as fundamental to understand cities and urban regions. Accordingly, accessibility instruments have been recognised as valuable support tools for land-use and transport planning. However, despite the relatively large number of instruments available in the literature, they are not widely used in planning practice. This paper aims to explore why accessibility instruments are not widely used in planning practice. To this end, we focus our research on perceived user-friendliness and usefulness of accessibility instruments. First, we surveyed some instrument developers, providing an overview of the characteristics of accessibility instruments available and on developers’ perceptions of their user-friendliness in planning practice. Second, we brought together developers and planning practitioners in some local workshops across Europe and Australia, where participants were asked to use insights provided by accessibility instruments for the development of planning strategies. We found that most practitioners are convinced of the usefulness of accessibility instruments in planning practice, as they generate new and relevant insights for planners. Findings suggest that not only user-friendliness problems but mainly organisational barriers and lack of institutionalisation of accessibility instruments, are the main causes of the implementation gap. Thus user-friendliness improvement may provide limited contributions to the successful implementation of accessibility concepts in planning practice. In fact, there seems to be more to gain from the active and continued engagement of instrument developers with planning practitioners and the institutionalisation of accessibility planning.

Validação do Youth Quality of Life Instrument para a população portuguesa: YQOL-R

É incontornável o estatuto que o conceito de qualidade de vida assume hoje na prática e políticas de saúde pública. Na infância e adolescência é ainda escassa a investigação, tornando-se crucial o desenvolvimento de instrumentos de qualidade vida relacionada com a saúde validados para esta população. O presente trabalho tem como objetivo fundamental analisar as qualidades psicométricas e validar a versão portuguesa do Youth Quality of Life (YQOL-R) (Patrick, et al., 2002). A amostra é constituída por 507 adolescentes, com idades compreendidas entre os 12 e os 19 anos, a frequentar o 3º ciclo do ensino básio e ensino secundário de escolas públicas do ensino regular. Para além do citado instrumento a validar, os jovens preencheram também, para a análise da validade convergente e divergente, o Kidscreen-27 (Gaspar & Matos, 2008) e a Escala da Depressão, Ansiedade e Stresse (EADS-21) (Pais-Ribeiro, Honrado & Leal, 2004). Os resultados mostram que o YQOL-R apresenta uma estrutura fatorial de quatro fatores, semelhantes à versão original americana (individual, relações sociais, ambiente e qualidade de vida em geral). Possui uma boa consistência interna e uma adequada estabilidade temporal. Mostrou correlações significativas e no sentido esperado com as variáveis em estudo. Foram igualmente encontradas diferenças de género em relação à qualidade de vida, sendo os rapazes a reportarem em média níveis mais elevados de perceção da qualidade de vida, comparativamente às raparigas. Futuros estudos devem ser realizados em amostras clínicas para confirmação dos dados. Não obstante esta limitação, o presente estudo contribuiu para a disponibilização de um novo instrumento para avaliação da qualidade de vida em crianças e adolescentes, o qual evidenciou boas propriedade psicométricas, apoiando, assim empiricamente, a sua utilização nas práticas de saúde e investigação em amostras da comunidade. / Nowadays, it´s unavoidable the status that, the concept of quality of life assumes in practices and politics of public health. In childhood and adolescence it´s weak the investigation but it´s crucial the development of instruments of quality of life related to health validated to this population. The present work has an important aim, it´s analyze the psychometric qualities and validate the Portuguese version of Youth Quality of Life (YQOL-R) (Patrick, et al., 2002). The sample consists of 507 adolescents, aged between 12 and 19 years old and they attend the 3 rd cycle of basic education and secondary education schools in villages of regular education. Apart from that instrument, teenagers fill in, also, to the analysis convergent and divergent, the Kidscreen-27 (Gaspar & Matos, 2008) and the Depression, Anxiety and Stress Scale (EADS-21) (Pais-Ribeiro, Honrado & Leal, 2004). The results show that the YQOL-R presents a factorial structure with four factors similar to original American version (individual, social relations, environment and general quality of life), presenting a good internal consistence and an adequate temporal stability. Substantial correlations showed and in the expected way with the variables in study. Have been found differences of gender related to quality of life, boys reported on average higher levels of quality of life perception, comparatively to the girls. Future studies must be performed in clinical samples to confirm the findings. In spite of this restriction, the actual study contributes to providing a new instrument to evaluate the quality of life in children and adolescents, this evidenced good psychometric properties, supported empirically its application in heath practices and investigation in community samples.

Programa de aquisição de alimentos (2003-2010): avaliação da implementação pela CONAB no Rio Grande do Norte

This thesis aimed to evaluate the implementation of the Food Acquisition Program(PAA) through CONAB RN in the period of 2003-2010 with the perception of all agents involved in the implementation of the government program.For the methodological trajectory it was adopted a descriptive bibliographical and documentary approach with triangular qualitative and quantitative, also called evaluative research.The theoretical model was supported by the authors Draibe (2001), Aguilar and Ander-Egg (1994) and Silva(2001), among others, that focused on family farming and evaluation of implementation of public policy having as a category of analysis the size implementation of policy and the latter divided into 10 theoretical dimensions.The universe consisted of three groups: the first were the managers and technicians from CONAB(RN and Brasilia), totaling 15 subjects. The second group was of associations/cooperatives that participated in the programin 2010, totaling a sample in each access of 15 representatives. The third group of subjects totaled with 309 representatives of governmental and non-governmental organizations that received donations of food for the same period. Semi-structured interviews and forms were adopted as instruments of data collection.The data were processed qualitatively by the analysis of content (interviews and documents) and quantitatively by means of statistical tests that allowed inferences and adoption of frequencies. Among the key find ingests that the program is not standing as a structure supported by planning. The interests of the performers do not necessarily converge with the objectives of the Food Acquisition Program (PAA). A shockof goals was identified (within the same program) when comparingthe financial agent (Ministry of Rural Development and of Social Development and Fight Against Hunger Ministry r) and the executor, CONAB/RN. Within the assessed dimensions, the most fragileis the sub-managerial decision-making and Organizational Environment and internal assessment, still deserves attention the sizeof logistical and operational Subsystem, as this also proved weak.The focusin the quest toexpand thequantificationof the resultsof theFood Acquisition Program (PAA)by CONAB/RN does forget a quality management focused on what really should be:the compliance with the institutional objectives of the government program.Finally, the perspective for the traded implementation should be re-examined because excessive discretion by managers along with technical staff has characterized there al role of the Food Acquisition Program (PAA) as public policy. We conclude that the implementation model, which apparently aggregates values to the benefitted citizens, has weakened the context of work on family farms having the management model of the implementation process be reviewed by the Federal Government and point too ther paths, which have as a guide line the emancipation and developmentof the field or in the field andat the same time enables the reduction of nutritional deficiency of beneficiaries in a balanced and coherent way

Conception, fabrication et caractérisation d'un biocapteur SPR à base de guides d'ondes photoniques sur substrat de verre

Résumé : Malgré le nombre croissant de capteurs dans les domaines de la chimie et la biologie, il reste encore à étudier en profondeur la complexité des interactions entre les différentes molécules présentes lors d’une détection à l’interface solide-liquide. Dans ce cadre, il est de tout intérêt de croiser différentes méthodes de détection afin d’obtenir des informations complémentaires. Le principal objectif de cette étude est de dimensionner, fabriquer et caractériser un détecteur optique intégré sur verre basé sur la résonance plasmonique de surface, destiné à terme à être combiné avec d’autres techniques de détection, dont un microcalorimètre. La résonance plasmonique de surface est une technique reconnue pour sa sensibilité adaptée à la détection de surface, qui a l’avantage d’être sans marquage et permet de fournir un suivi en temps réel de la cinétique d’une réaction. L’avantage principal de ce capteur est qu’il a été dimensionné pour une large gamme d’indice de réfraction de l’analyte, allant de 1,33 à 1,48. Ces valeurs correspondent à la plupart des entités biologiques associées à leurs couches d’accroche dont les matrices de polymères, présentés dans ce travail. Étant donné que beaucoup d’études biologiques nécessitent la comparaison de la mesure à une référence ou à une autre mesure, le second objectif du projet est d’étudier le potentiel du système SPR intégré sur verre pour la détection multi-analyte. Les trois premiers chapitres se concentrent sur l’objectif principal du projet. Le dimensionnement du dispositif est ainsi présenté, basé sur deux modélisations différentes, associées à plusieurs outils de calcul analytique et numérique. La première modélisation, basée sur l’approximation des interactions faibles, permet d’obtenir la plupart des informations nécessaires au dimensionnement du dispositif. La seconde modélisation, sans approximation, permet de valider le premier modèle approché et de compléter et affiner le dimensionnement. Le procédé de fabrication de la puce optique sur verre est ensuite décrit, ainsi que les instruments et protocoles de caractérisation. Un dispositif est obtenu présentant des sensibilités volumiques entre 1000 nm/RIU et 6000 nm/RIU suivant l’indice de réfraction de l’analyte. L’intégration 3D du guide grâce à son enterrage sélectif dans le verre confère au dispositif une grande compacité, le rendant adapté à la cointégration avec un microcalorimètre en particulier. Le dernier chapitre de la thèse présente l’étude de plusieurs techniques de multiplexage spectral adaptées à un système SPR intégré, exploitant en particulier la technologie sur verre. L’objectif est de fournir au moins deux détections simultanées. Dans ce cadre, plusieurs solutions sont proposées et les dispositifs associés sont dimensionnés, fabriqués et testés.

Big bang bifurcations in von Bertalanffy’s dynamics with strong and weak Allee effects

The main purpose of this work was to study population dynamic discrete models in which the growth of the population is described by generalized von Bertalanffy's functions, with an adjustment or correction factor of polynomial type. The consideration of this correction factor is made with the aim to introduce the Allee effect. To the class of generalized von Bertalanffy's functions is identified and characterized subclasses of strong and weak Allee's functions and functions with no Allee effect. This classification is founded on the concepts of strong and weak Allee's effects to population growth rates associated. A complete description of the dynamic behavior is given, where we provide necessary conditions for the occurrence of unconditional and essential extinction types. The bifurcation structures of the parameter plane are analyzed regarding the evolution of the Allee limit with the aim to understand how the transition from strong Allee effect to no Allee effect, passing through the weak Allee effect, is realized. To generalized von Bertalanffy's functions with strong and weak Allee effects is identified an Allee's effect region, to which is associated the concepts of chaotic semistability curve and Allee's bifurcation point. We verified that under some sufficient conditions, generalized von Bertalanffy's functions have a particular bifurcation structure: the big bang bifurcations of the so-called box-within-a-box type. To this family of maps, the Allee bifurcation points and the big bang bifurcation points are characterized by the symmetric of Allee's limit and by a null intrinsic growth rate. The present paper is also a significant contribution in the framework of the big bang bifurcation analysis for continuous 1D maps and unveil their relationship with the explosion birth and the extinction phenomena.

Récit d'expérience et entretiens réflexifs comme instruments de formation éducative : une étude narrative en garderie

Cette étude traite du rôle des entretiens réflexifs centrés sur la narration de cas vécus dans le cadre du projet «La carte des cas vécus» (Tochon et Toupin, 1993). Dans un premier temps, nous examinons le rôle des entretiens sous l'angle du soutien à la famille et de la formation parentale. Puis nous analysons leur rôle sous l'angle de la formation des éducatrices à la relation famille-garderie en général et du questionnement éthique en particulier. Il résulte de cette analyse que l'utilisation des entretiens réflexifs centrés sur la narration des cas vécus offre un soutien significatif aux parents, surtout en milieu défavorisé. Pour les éducatrices, bien qu'elles aient profité réflexivement de nos rencontres, un encadrement plus soutenu semble souhaitable avant qu'elles puissent utiliser de manière autonome ces outils. Nous concluons par des suggestions à cet effet et nous mettons en perspective la professionnalisation des éducatrices dans la relation famille-garderie et le soutien à la famille qu'elles peuvent apporter aux parents.

IFRS 9 ‘Financial instruments’: Anticipated effects of the standard change at Kesko Group

IFRS 9 Financial instruments presents the classification and measurement, the impairment and the hedge accounting requirements for accounting of financial instruments. The standard was set by the International Accounting Standards Board to replace IAS 39 Financial instruments: Recognition and Measurement on 1 January 2018. Hence, the long-criticized and complexly experienced requirements for accounting of financial instruments will undergo the most significant reform. This thesis addresses anticipated effects of IFRS 9, focusing on the challenges the new classification and measurement requirements bring forth in the case organization Kesko. This thesis was conducted as an action research, in which, a case study method was applied. The thesis was conducted with a twofold manner, which involved general analysis of IFRS 9 and further covered distinct ambitions related to the case organization. For the general part, empirical data was gathered by interviewing two IFRS experts from KPMG and PwC, while the interviews within the case organization constituted for the case study. Further, the literature on the IFRS 9 was such scant that the theoretical examination was merged with the IFRS experts’ quotations that also strived to contribute to the overall objective of reinforcing the body of research related to the subject. This thesis indicates that IFRS 9 will most fundamentally reform the impairment and the hedge accounting requirements of financial instruments. Regard to impairment, the changes are anticipated to increase the amount of loan-loss provisions, whereas the relaxed hedge accounting requirements are expected to encourage more companies to commence the application of hedge accounting. The thesis provides empirical support on that the term business model for managing financial assets, introduced in IFRS 9, is ably hard to comprehend and remains ambiguous. It goes on to argue that the most prominent issue in defining the business model for managing financial assets is the limits set in IFRS 9 for selling financial assets. In consideration of Kesko, this thesis finds that the key effects of IFRS 9 are anticipated to be the reshaping of the organization’s treasury policy and further examination of the possibility to apply hedge accounting for foreign exchange derivatives. What is more, the thesis presumes that complying the requirements of IFRS 9 Kesko will apply the hold to collect and sell model for managing financial assets in future.
