This thesis argues that Irish can and should be revitalized. Conducted as an observational study, this thesis focuses on interviews with 72 participants during the summer of 2013. All participants live in the Republic of Ireland or Northern Ireland. This thesis investigates what has caused the Irish language to lose power and prestige over the centuries, and which Irish language revitalization efforts have been successful. Findings show that although, all-Irish schools have had a substantial growth rate since 1972, when the schools were founded, the majority of Irish students still get their education through English-medium schools. This study concludes that Irish will survive and grow in the numbers of fluent Irish speakers; however, the government will need to further support the growth of the all-Irish schools. In conclusion, the Irish communities must take control of the promotion of the Irish language, and intergenerational transmission must take place between parents and their children.

Dans l’environnement hospitalier, les infirmiers jouent un rôle pivot dans la prestation de soin, cette population est particulièrement exposée à des niveaux élevés de demande émotionnelle ce qui peut entraîner à terme une insatisfaction, un épuisement professionnel (Dal Santo, Pohl & Battistelli, 2013), un sentiment d’impuissance et d’incapacité à accomplir un travail au niveau attendu (Davezies, 2007). Le soutien organisationnel perçu (SOP) a été supposé et démontré avoir la capacité d’atténuer les effets néfastes des tensions émotionnelles (Pohl, Battistelli & Librecht, 2013; Battistelli, Pohl & Dal Santo, 2012; George, Reed, Ballard; Halbesleben, 2006). Rhoades et Eisenberger (2002) ont ajouté que le soutien du supérieur hiérarchique (SSP) est défini par la perception qu’a le salarié de la manière dont son supérieur valorise sa contribution, et qui est considéré comme la variable qui contribue le plus significativement à la perception du soutien organisationnel. Rhoades et al (2001) ont observés un effet positif du SSP sur l’engagement organisationnel affectif ; (Wayne et al., 1997 ; Moorman et al., 1998) ont démontrés un effet direct du SSP sur le bien-être, la qualité de vie au travail et sur les comportements de citoyenneté organisationnelle. Enfin, le développement récent de la recherche confirme les effets tangibles du soutien du supérieur hiérarchique sur l’engagement affectif, l’intention de quitter et l’épuisement professionnel en témoignent Simons & Jankowski; 2008). Notre réflexion théorique s’articule en trois points. (1) Etudier les tensions psychologiques (conflit travail/famille-famille/travail) et les caractéristiques du travail (Demande psychologique, Contraintes physiques Complexité du travail…) constitue une clé d’entrée qui nécessite (2) une réflexion sur le soutien émotionnel au travail ainsi que les stratégies de régulation émotionnel comme variables modératrices, pour (3) étudier les effets de ces variables modératrices dans les modèles de recherche intégrant l’épuisement professionnel, l’engagement organisationnel, satisfaction au travail, la dissonance émotionnelle et le comportement de citoyenneté organisationnelle . Mots clé: Tensions au travail (conflit travail/famille-famille/travail) – Caractéristiques du travail (Demande psychologique, Contraintes physique, Complexité du travail) Burnout – Engagement organisationnel– Dissonance émotionnelle – comportement de citoyenneté_ Soutien émotionnel au travail –Stratégies de régulation émotionnelle. / The increasing demands of work and their impact on the quality of life of employees are timely. In this perspective, the reflection on the managerial practices deserves to be thorough. This research project has three objectives: to conceptualize, measure and predict the influence of emotional support at work (ESW) on organizational commitment, job satisfaction and organizational citizenship behaviour. Our reflection is based on three points. (1) Study the psychological tensions ( conflicts Work / family -life / work) and job characteristics (psychological demand, physical constraints, Complexity of work ... ) is a key input that requires (2) a reflection on the emotional support at work and emotional regulation strategies as moderating variables for ( 3) study the effects of moderating variables in integrating research models incorporating burnout, organizational commitment , emotional dissonance, job satisfaction and organizational citizenship behaviour. The hospital raises an exemplary manner the dynamics and challenges of local management. We will consider three cases: The University Hospital of Bab El Oued (Algeria), University Hospital of Brugmann, (Belgium) and The University Hospital of Bordeaux (France). To provide some answers, we mobilize two methods: qualitative and quantitative (more about a double measure of perceived SET and a measure of emotional regulation strategies) with a comparison of the target institutions. Key words : Emotional support at work_ psychological tensions (conflict work / life and family / work) - Work Characteristics (psychological demand, physical constraints, Labor Complexity ) Burnout – organizational commitment - emotional dissonance - organizational citizenship behaviour _ Strategies work emotional regulation .

Starting from single floor projects with simple flat slab frame, models with different numbers of floors are considered. The models do not use large rigidity elements such as staircases and lift shafts. The modeling used in this piece adopts simplified criteria for vertical action dimensioning, forming frames with flat slab layers taken as low height beams. These models are evaluated. Based on the results, the work analyzes the application validity of criteria to dismiss consideration of the NBR6118:2003 code presented second order global effort, and compares this against the P-∆ process utilization. Results both with and without inverted beams at the periphery are compared. / O presente trabalho aborda maneiras possíveis de avaliar estruturas de concreto armado destinadas a edifícios de múltiplos pavimentos quanto à instabilidade e necessidade de considerações de esforços de segunda ordem. A partir de plantas simples de estruturas em lajes planas, são considerados modelos com diferentes números de pavimentos. Os modelos não utilizam elementos de grande rigidez, como poços de elevadores e escadas. A modelagem utilizada adota os critérios simplificados para dimensionamento às ações verticais, formando pórticos com faixas de lajes admitidas como vigas de pequena altura. Estes modelos são avaliados. A partir dos resultados, analisa- se a validade a aplicação dos critérios para dispensa de consideração dos esforços globais de segunda ordem apresentados na NBR6118:2003, e se compara com a utilização do processo P-∆. São comparados resultados para estruturas com e sem utilização de vigas invertidas na periferia.

Ce travail porte sur l'étude des effets thermiques dans un palier hydrodynamique, alimentée par une rainure circonférentielle (CGJB) sous charge statique, en tenant compte des phénomènes de rupture de film dans la zone divergente. La recherche expérimentale a été réalisée à l'Université de Poitiers ; elle a permis une détermination minutieuse des champs de pression et de température sur la portée située à l’avant d’un CGJB et dans la section médiane de sa rainure. Ces mesures sous un régime stationnaire sont originales par rapport celles existantes, quel que le type de palier, de par le grand nombre de points de mesure, 180 pour la pression et 144 pour la température, l'instrumentation de haute précision, la large plage de conditions d'exploitation (pression spécifique variant de 0,125 à 2 MPa et vitesse linéaire de l’arbre allant de 5,25 à 21 m/s). Des études du régime transitoire de démarrage au régime stationnaire établi ont été effectuées pour de faibles charges. Des expériences effectuées à l'Université "Politehnica" de Bucarest ont montré une bonne corrélation entre la perte de portance, anti-portance et la rupture du film sur un patin Rayleigh (RSP), ce qui est essentiel pour l'évaluation des phénomènes de rupture dans les paliers. Quelques modèles théoriques ont été utilisés pour évaluer les risques de serrage au démarrage qui est une instabilité thermoélastique catastrophique. Les principaux résultats sont l’obtention d’une base fiable de données expérimentales permettant le développement des modèles théoriques avancés et l’infirmation d’une répartition de pression constante dans la zone divergente et de pression et température constantes dans la rainure d'alime / The main objective of the thesis is to study the thermal effects in steadily loaded circumferential groove journal bearings (CGJBs), including cavitation phenomena occurring in the divergent zone of such bearings. Experimental research conducted at University of Poitiers – Institut Pprime – France enabled a thorough determination of film pressure and temperature fields for the front land of a CGJB plus its mid-groove section, and several performance parameters. Measurements of film pressure and temperature fields under steady-state regime surpassed existing works, regardless of journal bearing design, through: sheer number of land measurement locations, 180 for pressure and for 144 temperature; high precision state of art instrumentation; broad range of operating conditions, 0.125 … 2 MPa specific bearing pressure and 5.25 … 21 m/s shaft speeds. Transient start-up to steady-statestabilization regimes have been investigated at low loads. Experiments at University "Politehnica" of Bucharest – Romania showed a correlation between the downforce thrust and film rupture for a Rayleigh step pin (RSP), important in evaluating divergent zone cavitation phenomena. Theoretical research consisted in developing simple models for evaluating CGJBs performance in steady-state and transient start-up regimes. Several theoretical models were employed for assessing start-up seizure, catastrophic transient thermoelastic instability and damage risk. The major result is a reliable experimental data collection that: enables development of advanced theoretical models; disprove flat film pressure distributions in divergent zones, and constant pressure and temperature in the bearing supply groov

La boîte de transmission principale (BTP) est une des principales sources dubruit perçu dans les cabines d’hélicoptères et pénalise fortement le confort acoustique deséquipages et passagers. Afin de réduire l’impact de cette source, les phénomènes acoustiqueset vibratoires mis en jeu par les boîtes de transmission à engrenages doivent être compris etsimulés durant les phases de développement. De cette façon, le comportementvibroacoustique des BTP pourra être amélioré dès la conception, réduisant ainsi le coût, lamasse et les difficultés d’intégration des solutions d’insonorisation. Ce travail présente lesBTP d’hélicoptères ainsi que le bruit qu’elles génèrent. Il présente également nosdéveloppements concernant la modélisation du comportement dynamique des BTP afin d’encalculer le bruit. Nous avons développé un code éléments finis permettant d’effectuer desétudes paramétriques afin d’ajuster le design des boîtes de transmission lors des phases dedéveloppement. Notre modèle est capable de calculer les efforts dynamiques aux paliers detransmissions composées de plusieurs engrenages cylindriques et spiro-coniques. Enfin, nousanalysons des mesures acoustiques et vibratoires effectuées autour de deux BTP pourplusieurs conditions de couple et vitesse. Ces mesures nous permettent de mieux comprendrele comportement vibroacoustique des BTP et de confirmer certaines tendances observées avecnotre modèle / Main gearbox (MGB) is one of the main noise sources in helicopter cabinsand it strongly penalizes acoustic comfort of crews and passengers. In order to reduce theimpact of this source, acoustic and vibration mechanisms of gearboxes have to be understoodand simulated during the development phases. By this way, MGB vibroacoustic behaviourcould be improved by design, thus reducing cost, additional weight and integration difficultiesof sound-proofing solutions. This work presents helicopters MGB and the noise they generate.It also presents our developments regarding the modelling of MGB dynamic behaviour fornoise computation. We have developed a finite elements code allowing to conduct parametricstudies to tune the gearboxes design in early development phases. Our model is able tocompute dynamic loads on bearings of any transmission composed of several cylindrical andspiral bevel gears. At last, we analyse acoustic and vibration measurements done around twoMGB for several conditions of torque and speed. These measurements allow to betterunderstand MGB vibroacoustic behaviour and to confirm some trends observed with ourmodel

<p>The electrification trend affecting off-road vehicles is paving the way toward dedicated electrified hydraulic actuation systems. Although traditional centralized fluid power architectures are still utilized in many applications for low cost, power density, and reliability, nowadays emission policy results in an increasing interest in developing electro-hydraulic actuator (EHA) solutions. EHAs enable non-throttling actuation and energy recuperation during overrunning loads, leading to higher transmission efficiency and lower fuel consumption. These features in energy efficiency make EHAs competitive in meeting emission regulations compared to conventional hydraulic solutions.</p> <p>The key challenge in developing the EHA solution comes from the high cost and space requirements, especially for the adoption of self-contained EHAs in mobile applications. In this study, two architectures for the EHA are proposed, a closed-circuit architecture and an open-circuit one, to determine the most practical and efficient configuration. The most effective open-circuit architecture with distributed concepts is further investigated for implementation, which requires less modification of the mechanical structures and performs more efficiently than the closed-circuit alternative. The proposed EHA is driven by an electro-hydraulic unit (EHU) consisting of a variable-speed electric motor and a fixed-displacement hydraulic pump, which is relatively cost-effective. A novel hydraulic configuration is proposed, which allows the EHA to cover full-speed operating ranges in four quadrants. </p> <p>To verify the EHA design, the behavior of the proposed system should be predicted prior to costly experiments and demonstrations. For this purpose, an integrated simulation model is developed based on the lumped parameter approach in the Amesim environment. The model includes the electric system, the hydraulic system, and the mechanism to be implemented, which are capable of flexible analysis of functionality, efficiency, and thermal performance.</p> <p>In this work, a dedicated test rig for EHA testing is developed. The test rig can help verify EHA performance, test the control algorithm, and diagnose errors before implementing the system on real applications. The experimental results from the test rig also validate the simulation model. An independent load drive of the test rig allows testing all possible  loading conditions of the proposed EHA, thus demonstrating the energy performance in four quadrants. Thermal behavior is investigated with long duty cycles to determine the need for additional cooling equipment. After the validation of the hydraulic configuration, a power electronics setup is added to the test rig, which allows to drive the EHA system with the novel designed EHUs. Validation on the test platform paves the way for implementation in a vehicle. </p> <p>As a final step, the proposed EHA system is implemented in a reference vehicle, a Case New Holland TV380 skid steer loader. A novel designed EHU is adopted to drive the system for technology demonstration. The energy savings capacity of the EHA is investigated in comparison to the baseline measurements of the traditional open-center hydraulic architecture. The impressive savings from the reduction of throttling losses and energy recovery guide the possible commercialization of such EHAs in mobile hydraulic applications. The controller design of the implemented EHA system is investigated with the aim of improving the dynamic performance, e.g., reducing damping oscillation. Basic power management strategies are also studied to integrate EHA with the power train of current hydraulic machines. Regarding future work, based on this research but not within the scope of this study, the proposed EHA system can be adopted with different types of prime movers, such as axial piston machines as the hydraulic part of an EHU. Furthermore, the design approach proposed in this study can help resize the EHA system for other applications with different loading conditions and power requirements, and the energy savings capability can be further investigated. With this, a comprehensive market analysis will be performed for the commercialization of EHA. </p>

Existentiell hälsa är ett relativt nytt begrepp i Sverige och handlar om vårt sätt attse på och förhålla oss till livet i stort. Trots vissa påvisade hälsoeffekter, harmöjligheten att träna den existentiella hälsan på arbetstid ännu inte nått sammastatus som möjligheten att träna och förbättra den fysiska och psykosocialahälsan.Studiens syfte var att undersöka erfarenheter och upplevda effekter av enarbetsplatsförlagd hälsointervention under en serie av åtta tillfällen, medutgångspunkt i den existentiella hälsoaspekten. Semistrukturerade intervjuergenomfördes med sex informanter som genomgått hälsointerventionen under detsenaste året. Studien är kvalitativ och materialet analyserades med den tolkandefenomenologiska analysmetoden (IPA). Fyra huvudteman identifierades varav detre första kopplas till erfarenheter och det sistnämnda till egenupplevda effekter:Att bli sedd och uppskattad; Vikten av delandet; Existentiell hälsa – en del av migoch Ett nytt förhållningssätt. Resultatet visar på mycket positiva erfarenheter avatt ha blivit sedd som människa mer än som arbetstagare samt en stark gemenskapmed övriga deltagare. Resultaten indikerar en ökad grad av öppenhet och tillit,både till sig själv och till sina kollegor, i takt med träffarna. Detta gav pågruppnivå en upplevd ökad effektivitet i dagliga arbetsuppgifter tack vareförbättrad samarbetsförmåga. På individnivå indikeras en upplevd ökad inrestyrka tack vare starkare självkänsla och integritet. Slutsatsen vi drar av studienär att gruppträning i existentiell hälsa är ett kompletterande verktyg i kampen förförbättrad hälsa, ökad arbetsglädje och effektivitet. / Existential health is a relatively new concept in Sweden and is about our way oflooking at and relating to life in general. Despite some proven health effects, theopportunity to exercise existential health during working hours has not yetreached the same status as the opportunity to exercise and improve physical andpsychosocial health.The purpose of the study was to investigate experiences and perceivedeffects of a workplace-based health intervention over a series of eight occasions,based on the existential health aspect. Semi-structured interviews were conductedwith six informants who had undergone the health intervention during the pastyear. The study is qualitative and the material was analyzed using the interpretivephenomenological analysis method (IPA). Four main themes were identified, ofwhich the first three are linked to experiences and the latter to self-perceivedeffects: Being seen and appreciated; The importance of sharing; Existential health- a part of me and A new approach. The results show very positive experiencesof having been seen as a human being more than as an employee and a strongcommunity with other participants. The results indicate an increased degree ofopenness and trust, both to oneself and to one's colleagues, during the meetings.At a group level, this resulted in a perceived increase in efficiency in daily tasksthanks to improved collaboration skills. At the individual level, a perceivedincreased inner strength is indicated thanks to stronger self-esteem and integrity.The conclusion we draw from the study is that group training based on existentialhealth is a complementary tool in the fight for improved health, increased jobsatisfaction and efficiency.

The honor killing of Fadime Sahindal in 2002 sparked a debate in Swedish media about honor-related violence and oppression. As a professional social worker, it is important to have knowledge in the field to help young women who are exposed to honor-related violence and oppression. The aim of this study is to analyze the working methods and attitudes of social workers and their discretion in the work of honor-oppressed young women. The study is based on six qualitative interviews conducted with professional social workers. Through the interviews, the social workers' experiences, thoughts and opinions about the social service's way of working with honored young women were highlighted. The interviews were analyzed using thematic analysis and interpreted by the theory of honor and discretion. The results show that social workers do not have the right knowledge about honor problems and that they do not have the right tools to meet these young women who are exposed to violence and oppression.

Syftet med studien är att ta reda på de bidragande faktorerna för etableringen av afghanska ensamkommande barn i det svenska samhället och därmed bidra till kunskapsutveckling om målgruppens behov hos yrkespersoner som kommer i kontakt med dessa barn. En kvalitativ metod har applicerats på studien. Studiens frågeställningar har besvarats med semistrukturerade intervjuer av åtta etablerade respondenter som har kommit som ensamkommande barn till Sverige. Utifrån tidigare forskning som handlar om ensamkommande barn och de tre teorierna systemteori, KASAM och Bourdieus fyra kapitalformer, har studiens material analyserats. Studien visar att myndigheternas insatser och stöd har varit uppskattade och betydelsefulla hos ensamkommande barn i deras etableringsprocess. Det framkommer att en kombination av flera yrkespersoners stöd och insatser, exempelvis av socialsekreterare, lärare, boendepersonal, vuxna volontärer, vänner, god man och kontaktperson, har spelat stor roll i ungdomarnas etablering. Studien visar därtill att några centrala faktorer såsom uppehållstillstånd, skapande av sociala nätverk, språkkunskap och yrkespersoners genuina intresse och engagemang att stötta dessa ungdomar, har varit avgörande för dessa ensamkommande barn att komma in i det svenska samhället. Det visas tydligt i studien att ungdomarnas egna ambitioner, drivkrafter, styrka, strategier, vilja och att målmedvetenhet har varit väsentliga i deras etablering. / The purpose of this study is to identify the contributing factors for the establishment of afghan unaccompanied children in Swedish society and thereby contribute to increasing knowledge among professionals who come into contact with this group. A qualitative method has been applied in the study and eight established participants who arrived as unaccompanied children to Sweden have been interviewed through semi-structured interviews. The results have been analysed based on some previous national and international researches on unaccompanied children and also on three theories: system theory, KASAM and Bourdeius' four forms of capital. The study shows that the efforts and support of the authorities have been significant and appreciated by unaccompanied minors in their establishment process. The study also declares that the participation of several professionals, for instance social workers, teachers, housing staff, volunteering adults, friends, gaurdian and contact person have played a major role in the young people’s establishment. Furthermore, the study shows that some central factors such as a residence permit, to have social networks, knowledge of the Swedish language and the extra support from the people involved have been essential for getting into the Swedish society. It is clearly shown in the study that the young peoples’ own ambitions, self motivation, struggles, own strategies, and being purposeful have been essential in their establishment.

Background: The care for the older adults is facing major challenges with the growing proportion of older people. This entails a need to find new ways to cope with the tasks of elderly care, and digitalization is seen as part of the solution. In order to succeed with digitalizing, the first-line managers in elderly care needs knowledge of change management and digitalization. That knowledge needs to be obtained via educational efforts. Aim: The aim of the study was to examine the experiences of first-line managers within elderly care after they recieved training in change management and digitalization. The aim was further to examine their perspectives on the influencing factors when it comes to leading change management in digitalization. Method: The method was a qualitative interview study with an inductive research approach and the sample consisted of first-line managers within elderly care in a medium-sized Swedish municipality. Semi-structured interviews were conducted which were analyzed by qualitative inductive content analysis.  Results: Four main categories emerged; perspectives on implemented educational efforts; identified potential, barriers and needs in change management and digitalization; responsibilities and roles in change management and digitalization; and perspectives on care users when using health and welfare technology. Potential and barriers included assent from management, cooperation between colleagues, influence of the first-line managers' level of interest, resources, goals and strategies. It also included prioritization of daily operations, employee needs, resistance and information about purpose, implementation process and technology. In order for the first-line managers in elderly care to achieve the expected benefit with training on change management and digitalization, the expectations needs to be well defined. Conclusion: Educational efforts in change management and digitalization alone are not enough to achieve a successful implementation of health and welfare technology in municipal care for the elderly. Digitalization is an ongoing process of changes and the first-line managers can-not do it by themselves. The preferred practice is to be able to create the conditions for interested employees to drive the work of digitalization within their respective operation.
