Disertační práce Porovnávání středoevropských jazyků: za horizont strukturních rysů a lexikálních přejímek se soustředí na zhodnocení a přehodnocení přístupu k výzkumu jazyků střední Evropy. Hlavním cílem předkládané práce je (1) podat přehled dosavadních poznatků o porovnávání středoevropských jazyků, (2) na jeho základě naznačit možné nové směřování němu přispět. Druhá kapitola práce se věnuje areálové lingvistice, jakožto disciplíně zaměřené na výzkum podobnosti a konvergence geograficky blízkých jazyků, a zejména jejímu ústřednímu pojmu . Představuje okolnosti jeho vzniku, jeho různé definice a jeho kritické (pře)hodnocení pracích současných areálových lingvistů. Třetí kapitola sumarizuje výzkum středoevropských jazyků: různé koncepce středoevropského (popř. dunajského) jazykového svazu vzájemné vlivy lexika a frazeologie těchto jazyků a popisy situací jazykového kontaktu v areálu. Tento přehled ukázal, že hlavními doménami porovnávání jazyků areálu dosud byly strukturní rysy a lexikální přejímky a kalky. Novější vývoj lingvistiky, jak je naznačeno ve čtvrté kapitole, však operuje rovněž s jazykovými jednotkami, které překlenují a relativizují -lexikon. Nabízí se tedy, aby se rovněž komparativní výzkum středoevropských jazyků soustředil na tyto jevy zahrnutelné pod pojem idiomatičnosti. Pátá kapitola...

Les systèmes de dialogues sont à même de révolutionner l'interaction entre l'homme et la machine. Pour autant, les efforts pour concevoir des agents conversationnels se sont souvent révélés infructueux, et ceux, malgré les dernières avancées en apprentissage profond et par renforcement. Les systèmes de dialogue palissent de devoir opérer sur de nombreux domaines d'application mais pour lesquels aucune mesure d'évaluation claire n'a été définie. Aussi, cette thèse s'attache à étudier les dialogues débouchant sur un objectif clair (goal-oriented dialogue) permettant de guider l'entrainement, et ceci, dans des environnements multimodaux. Plusieurs raisons expliquent ce choix : (i) cela contraint le périmètre de la conversation, (ii) cela introduit une méthode d'évaluation claire, (iii) enfin, l'aspect multimodal enrichie la représentation linguistique en reliant l'apprentissage du langage avec des expériences sensorielles. En particulier, nous avons développé GuessWhat?! (Qu-est-ce donc?!), un jeu imagé coopératif où deux joueurs tentent de retrouver un objet en posant une série de questions. Afin d’apprendre aux agents de répondre aux questions sur les images, nous avons développés une méthode dites de normalisation conditionnée des données (Conditional Batch Nornalization). Ainsi, cette méthode permet d'adapter simplement mais efficacement des noyaux de convolutions visuels en fonction de la question en cours. Enfin, nous avons étudié les tâches de navigation guidée par dialogue, et introduit la tâche Talk the Walk (Raconte-moi le Chemin) à cet effet. Dans ce jeu, deux agents, un touriste et un guide, s'accordent afin d'aider le touriste à traverser une reconstruction virtuelle des rues de New-York et atteindre une position prédéfinie. / While dialogue systems have the potential to fundamentally change human-machine interaction, developing general chatbots with deep learning and reinforce-ment learning techniques has proven difficult. One challenging aspect is that these systems are expected to operate in broad application domains for which there is not a clear measure of evaluation. This thesis investigates goal-oriented dialogue tasks in multi-modal environments because it (i) constrains the scope of the conversa-tion, (ii) comes with a better-defined objective, and (iii) enables enriching language representations by grounding them to perceptual experiences. More specifically, we develop GuessWhat, an image-based guessing game in which two agents cooper-ate to locate an unknown object through asking a sequence of questions. For the subtask of visual question answering, we propose Conditional Batch Normalization layers as a simple but effective conditioning method that adapts the convolutional activations to the specific question at hand. Finally, we investigate the difficulty of dialogue-based navigation by introducing Talk The Walk, a new task where two agents (a “tourist” and a “guide”) collaborate to have the tourist navigate to target locations in the virtual streets of New York City.

Abstract. Autonomous agents, also known as AI agents, are staples in modern video games. They take a lot of roles, everything from being quest-givers in roleplaying games, to opposing forces in action- and shooter games. Crafting an AI that is not only easy to create, but also retains humanlike and believable behavior, has always represented a challenge to the development industry, and has in several cases ended up with open world games using AI systems that limit the AI agents to simple moving patterns. In this thesis, a form of AI systems more commonly used in simulation games such as The Sims video game series, are taken and implemented in an environment that could possibly be seen in an open world game. After the implementation, a set of tests were performed on a group of testers which resulted in the insight that a majority of the testers, when asked to compare their experience to other games, found this implementation to feel more lifelike and realistic.

Bakgrund och problemdiskussion: Inom organisationer är vd:n ett hett och debatterat samtalsämne när det kommer till verksamhetsstyrning. Inom små till medelstora verksamheter är det inte ovanligt att ägaren är både ägare och vd för verksamheten, vilket betecknas som ett ägarlett företag. När ett företag går från ett ägarlett styre till en extern vd kan det ha en stor inverkan på verksamheten. Ett byte av vd innebär att en ny person kommer att bestämma hur verksamhetens styrning ska utformas och implementeras. Fortsättningsvis innebär det ett stort steg för ägaren när den ska frånsäga sin vd-position och lämna över till en extern vd. Det finns två olika teorier som förklarar relationen mellan ägare och vd. Agentteorin, som antar att människor agerar utifrån sitt eget intresse, och stewardshipteorin, som utgår från att människor agerar utifrån verksamhetens bästa. Syfte: Syftet med studien är att undersöka om verksamhetsstyrning förändras i samband med att en extern vd intar vd-rollen i ett tidigare ägarlett företag. Ytterligare kommer studien att undersöka hur ägaren och den externa vd:n ser på skiftet när en extern vd intar vd-rollen utifrån agentteorin och stewardship. Metod: Studien är en fallstudie som undersöker två företag som har genomgått ett skifte från ägarlett styre till externt styre. Denna studie kompletteras med inblick och erfarenhet från rekryterare inom högre befattningar. Studien utgår från en kvalitativ forskningsstrategi, med induktiva forskningsval som har abduktiva anslag. Det empiriska materialet har samlats in via sju stycken respondenter via semistrukturerade intervjuer. Slutsats: De slutsatser som kan dras från studien är att verksamhetsstyrningen förändras till att bli mer målstyrd när företaget går från ett ägarlett styre till att en extern person intar vd-rollen. Både ägare och vd från respektive verksamhet visar en skiftning av både opportunistiskt beteende och beteende som liknar en ‘steward’. Det innebär att det inte finns ett svart-vitt beteende avseende om individerna agerar efter sitt eget bästa eller efter verksamhetens bästa. Deras synsätt och agerande uppvisar en kombination av båda teorierna i samband med att verksamheten blir mer professionell, strategisk och målstyrd. / Background: Within organisations, the CEO is a well-known and debated subject when it comes to corporate governance in small to medium-sized enterprises (SMEs). When a company moves from an owner-led governance to an external CEO, it can have a major impact on the business. An alteration in the role of CEO would allow for a change in the governance of the business, through potential new individualistic implementations and structural decisions. Furthermore, it is a largely significant step for the owner to relinquish the position of CEO to an external individual. There are two different theories to explain the relationship between owners and CEOs. Agent theory, which assumes that people act in their own interest, and stewardship theory, which assumes that people act in the best interests of the business. Purpose: The purpose of the thesis is to investigate whether corporate governance changes when an external person is appointed CEO in a previously owner-managed company. Furthermore, this thesis will investigate how both the owner and the external CEO perceive the transition when the role of CEO is assigned to an external individual based on agent theory and stewardship theory. Method: The study is a case study examining two case companies that have experienced a shift from owner-led governance to external governance, along with the insight and experience of two senior recruiters. The study is based on a qualitative research strategy, with specific attention to inductive research choices and abductive approaches. The empirical material has been collected via semi-structured interviews and the involvement of seven respondents. Conclusion: The conclusion that can be drawn from the thesis is that the corporate governance changes and becomes more goal-oriented when an external person is the CEO. Both owners and CEOs from each business have a tendency towards both opportunistic and steward-like behavior. This means that there is no specific behavior regarding whether they act in their own best interests or in the best interests of the business. Their views and actions reflect a combination of both theories as the organisation becomes more professional, strategic and goal- oriented.

Ce travail de recherche vise à contribuer au développement de nouveaux outils d'estimation d'erreur globale et locale en ingénierie mécanique. Les estimateurs d'erreur globale étudiés reposent sur le concept d'erreur en relation de comportement à travers des techniques spécifiques de construction de champs admissibles, assurant l'aspect conservatif ou garanti de l'estimation. Une nouvelle méthode de construction de champs admissibles est mise en place et comparée à deux autres méthodes concurrentes, en matière de précision, coût de calcul et facilité d'implémentation dans les codes éléments finis. Une amélioration de cette nouvelle méthode hybride fondée sur une minimisation locale de l'énergie complémentaire est également proposée. Celle-ci conduit à l'introduction et à l'élaboration de critères géométriques et énergétiques judicieux, permettant un choix approprié des régions à sélectionner pour améliorer localement la qualité des champs admissibles. Dans le cadre des estimateurs d'erreur locale basés sur l'utilisation conjointe des outils d'extraction et des estimateurs d'erreur globale, deux nouvelles techniques d'encadrement de l'erreur en quantité d'intérêt sont proposées. Celles-ci sont basées sur le principe de Saint-Venant à travers l'emploi de propriétés spécifiques d'homothétie, afin d'améliorer la précision des bornes d'erreur locale obtenues à partir de la technique d'encadrement classique fondée sur l'inégalité de Cauchy-Schwarz. Les diverses études comparatives sont menées dans le cadre des problèmes d'élasticité linéaire en quasi-statique. Le comportement des différents estimateurs d'erreur est illustré et discuté sur des exemples numériques tirés d'applications industrielles. Les travaux réalisés constituent des éléments de réponse à la problématique de la vérification dans un contexte industriel. / This research work aims at contributing to the development of innovative global and goal-oriented error estimation tools applied to Computational Mechanics. The global error estimators considered rely on the concept of constitutive relation error through specific techniques for constructing admissible fields ensuring the recovery of strict and high-quality error estimates. A new hybrid method for constructing admissible stress fields is set up and compared to two other techniques with respect to three different criteria, namely the quality of associated error estimators, the computational cost and the simplicity of practical implementation into finite element codes. An enhanced version of this new technique based on local minimization of the complementary energy is also proposed. Judicious geometric and energetic criteria are introduced to select the relevant zones for optimizing the quality of the admissible fields locally. In the context of goal-oriented error estimation based on the use of both extraction techniques and global error estimators, two new improved bounding techniques are proposed. They lean on Saint-Venant's principle through specific homotheticity properties in order to obtain guaranteed and relevant bounds of better quality than with the classical bounding technique based on the Cauchy-Schwarz inequality. The various comparative studies are conducted on linear elasticity problems under quasi-static loading conditions. The behaviour of the different error estimators is illustrated and discussed through several numerical experiments carried out on industrial cases. The associated results may open up opportunities and help broaden the field of model verification for both academic research and industrial applications.

Adolescent pregnancies are high risks obstetric occurrences. Antenatal care (ANC) provides opportunities to recognise and treat obstetric complications, enhancing the pregnancy outcomes for mothers and babies. This study investigated factors influencing pregnant adolescents' utilisation of ANC services in Bulawayo, using the Health Belief Model's major tenets. A quantitative descriptive design was used in four phases: 80 adolescents' ANC records were audited; structured interviews were conducted with 200 adolescents attending ANC and with 80 adolescents who had delivered their babies without attending ANC; and 52 midwives completed questionnaires portraying their perceptions on adolescents' utilisation of ANC services in Bulawayo. Documentation of ANC services provided to adolescents did not meet the expected standards. Poor or non utilisation of ANC services was influenced by socio demographic factors, individual perceptions of adolescents about antenatal care, perceived benefits of and perceived barriers to the utilisation of ANC. Most pregnant adolescents could not access these services because they could not pay the ANC and/or delivery fees charged at government clinics/hospitals. Midwives required more training in providing and recording adequate ANC services. Free ANC and delivery services could enhance adolescents' pregnancy outcomes in Zimbabawe. An information brochure on the importance of ANC attendance for adolescents has been compiled, based on the research results (see Annexure J). / Health Studies / D.Litt. et Phil. (Health Studies)

Syftet med denna magisteruppsats har varit att utforska hur Covid-19 pandemin har påverkat ledarskapet och organisationens riktning.    Covid-19 pandemin har påverkar olika delar av ledarskapet. Resultaten visar tydligt att chefer känner sig överbelastade eftersom de måste hantera många administrativa uppgifter och alternerande möten. På grund av brist på tid och balans mellan arbete och privatliv har förmågan att ha en helhetssyn, tolka och ta in perspektiv utifrån och in och inifrån och ut varit en utmaning för ledarna. Resultatet indikerar även på behovet av tydliga kommunikationskanaler mellan ledarna, de anställda och deras kunder om vilka åtgärder som krävs för att anpassa sig till den nya situationen som pandemin har medfört.   Under pandemin har organisationerna tvingats att vidta snabba åtgärder baserat på föreskrifterna och begränsningarna från Folkhälsomyndigheten och regeringen. Etablerade digitala kanaler har använts men nya digitala kanaler har behövts identifieras för att skapa interaktion och relationer inom organisationen samt med kunderna.   Den snabba omvandlingen till den digitala världen har påverkat organisationens riktning att tänka annorlunda, vara mer flexibel och anpassningsbar till nya oväntade förändringar, såsom pandemin. Organisationerna har använt nyckelindikatorer för att identifiera och få en tydlig bild av hur pandemin har påverkat organisationens riktning internt och externt gentemot sina kunder. Denna nya digitala omvandling har också tvingat kunderna att gå in på nya digitala plattformar och interagera online med organisationerna. Den nya digitala medvetenheten från kunderna har framkallat nya digitala krav och tjänster som i sin tur har resulterat i behov av nya digitala självservice tjänster och en högre och starkare digital kompetens från organisationens kundtjänst.   En bidragande diskussion till organisationerna och samhället är att hänvisa till begreppet lönsamhet som en värdeskapande effekt som är hållbar över tid, kopplad till tre element: ledarskap, organisationens riktning och kundbehov. / The purpose of this thesis has been to explore how the Covid-19 pandemic has affected the leadership and the direction of the organization.   The Covid-19 pandemic has affected various parts of the leadership. The results clearly indicate that managers feel overloaded since they have to handle a lot of administrative tasks and alternating meetings. Due to lack of time and balance between work and private life, the ability to have a holistic view, interpret and take in perspectives from outside-in and inside-out has been a challenge for the leaders. The results also indicated the need for clear communication between the leaders and the employees and their customers about what actions are required in order to adapt to the new situation that the pandemic has imposed.   During the pandemic the organizations were forced to take fast action based on the regulations and restrictions from the Public Health Agency and the government. Established digital channels were used but new digital channels had to be identified to create interaction and relations within the organization and with the customers.  The fast transformation to the digital world has affected the direction of the organization to think differently and be more flexible and adaptable to new unexpected changes, such as the pandemic. The organizations have used key indicators to identify and get a clear picture of how the pandemic has affected the direction of the organization internally and externally towards its customers. This new digital transformational shift has also forced the customers to enter new digital platforms and interact online with the organizations. The new digital awareness from the customers has induced new digital requirements and services which in turn have resulted in the need for new digital self-services and a higher and stronger digital competence from the organizations customer service.   A contributing discussion to the organizations and to the society is to refer to the concept of profitability as a value-creating effect sustainable over time, connected by three elements: leadership, direction of the organization and customer need. / <p>2021-06-06</p>
