Designing Game Narrative to Evoke Players’ Empathy

Guo, Yu January 2022 (has links)
The paper would focus on the game narrative and empathy, more specifically, the primary goal of this paper is to see how game narrative evokes players’ empathy and get some narrative design principles that can be used in future game design and research. To fulfill the research goal of the paper, I will analyze three role-playing games To the Moon(2011), A Bird Story(2014), and Finding Paradise(2017). They are all developed by a designer Kan Gao, and focus on storytelling, especially To the Moon, receiving praise for its narrative and was given the "Best Story" award by GameSpot(“To the Moon,” 2022). The result of the paper can complement the study on the intersection of game narrative and empathy, also it can supply some practical cases in the game field for Keen’s(2006) narrative empathy theory. And the study can help researchers to study deeper in this field, and provide more empathic narrative design strategies for game designers. And those devices about plot twists, flashbacks, camera angles, etc, may also apply to the literature and film creation for evoking the audience’s empathy.

Det osynliga våldet : En kvalitativ innehållsanalys av nyhetsrapporteringen om våld i äldres parrelationer / The Invisible Violence : A qualitative content analysis of news reporting regarding intimate partner violence in elderly couples

Lindström, Emilia January 2022 (has links)
Syftet med denna studie var att få kunskap om hur nyhetsmedia rapporterar om våld i äldres parrelationer. Fokus var att studera hur våldet framställs och förklaras samt hur förövare, offer och deras relation framställs i nyhetsartiklar. Studien utgår från en förståelse att medias framställning av våldet påverkar allmänhetens uppfattning om våldet. Med utgångspunkt i detta syftar studien till att få ökad kunskap om vilken bild av våld i äldres parrelationer som kommuniceras till allmänheten genom nyhetsmedia.  Denna kvalitativa studie baseras på totalt 33 stycken nyhetsartiklar publicerade mellan januari 2019 och mars 2022 i Dagens Nyheter, Svenska dagbladet, Expressen och Aftonbladet. Resultatet visar på att nyhetsrapporteringen främst handlar om dödligt våld. Våldet förstås som enskilda och isolerade händelser, där en förståelse av våldet som våld i nära relation är frånvarande. Beskrivningarna av förövare, offer och deras relation gör att de framställs enligt ålderistiska och stereotypa bilder av äldre. / The purpose of this study was to gain knowledge about how the news media reports on intimate partner violence among elderly couples. The focus was on studying how the violence is portrayed and explained and how perpetrators, victims and their relationships are portrayed in news articles. The study is based on an understanding that the media's portrayal of the violence affects the public's perception of the violence. Based on this, the study aims to gain increased knowledge about the image of violence in the elderly’s couple relationships that is communicated to the public through news media.  This qualitative study is based on a total of 33 news articles published between January 2019 and March 2022 in the Swedish newspapers Dagens Nyheter, Svenska Dagbladet, Expressen and Aftonbladet. The results show that the media’s reporting is mainly about lethal violence. The violence is portrayed as individual and isolated events, where an understanding of the violence as domestic violence is absent. The media's descriptions of perpetrators, victims and their relationships lead to that they are presented according to ageist and stereotypical images of the elderly.

Multiple Asteroid Retrieval Mission

Gargioni, Gustavo 11 May 2020 (has links)
In this thesis, the possibility of enabling space-mining for the upcoming decade is explored. Making use of recently-proven reusable rockets, we envision a fleet of spacecraft capable of reaching Near-Earth asteroids. To analyze this idea, the goal of this problem is to maximize the asteroid mass retrieved within a spacecraft max life span. Explicitly, the maximum lifetime of the spacecraft fleet is set at 30 years. A fuel supply-chain is proposed and designed so that each spacecraft is refueled before departing for each asteroid. To maximize access to the number of asteroids and retrievable mass for each mission, we propose launching each mission from an orbit with low escape velocity. The L2-Halo orbit at the libration point in the Earth-Moon system was selected due to its easy access from Low-Earth Orbit and for a cislunar synergy with NASA Gateway. Using data from NASA SmallBody and CNEOS databases, we investigated NEAs in the period between 2030 and 2060 could be captured in the ecliptic plane and returned to L2-Halo with two approaches, MARM-1 and MARM-2. Together, these databases provide all information for every asteroid's close approach known today. Returning the asteroid as a whole is explored in the MARM-1 method, while MARM-2 evaluates the possibility of reaching larger asteroids and returning a fragment of their masses, such that it optimizes the available cargo weight per time of flight of each mission. The following results are compared with previous work from the community. The results show a 96% reduction in the cost per kg, with an enormous increase in retrieved mass. With these results, this thesis shows that not solely energy or dynamic optimization will be responsible for proving space mining feasibility, but rather a combination of those and business best practices. Proving feasibility for space mining is a complex and immense problem. Although this thesis opens new possibilities for future work on the field and sparkes the interest of private endeavors, the final solution for this problem still requires additional exploration. / M.S. / In this thesis, the possibility of enabling space-mining for the upcoming decade is explored.

L'impact d'un accident vasculaire cérébral léger sur la qualité de vie des proches

Tellier, Myriam 04 1900 (has links)
Introduction : Les personnes ayant eu un accident vasculaire cérébral léger (AVCL) sont autonomes pour l’accomplissement des activités de la vie quotidienne de base, mais peuvent présenter des déficits subtils pour l’accomplissement d’activités complexes qui ne sont pas dépistés durant l’hospitalisation. Le retour à domicile parmi les proches est souvent le moment où certaines difficultés apparaissent. L’objectif de cette étude est d’explorer la perception des proches de leur qualité de vie, trois mois après le retour à domicile de la personne ayant eu l’AVCL. Méthodologie : Cette étude qualitative repose sur un paradigme constructiviste. Des entrevues individuelles semi-dirigées ont été menées à l’aide d’un guide d’entrevue, auprès de proches de personnes ayant eu un premier AVCL trois mois auparavant. Une transcription du contenu des entrevues a été faite sous forme de verbatim, suivie d’une analyse de contenu. Résultats : Huit entrevues ont été complétées (âge moyen 56,9 ans – ratio hommes/femmes de 2/6). Six thèmes ont été identifiés : personne ayant eu l’AVCL, vie quotidienne, relation conjugale, récidive, santé et services. L’AVCL engendre plusieurs incapacités (personne ayant eu l’AVCL) et les proches interrogés rapportent une augmentation de leurs tâches quotidiennes ce qui limite leurs activités personnelles (vie quotidienne). Ils mentionnent également devoir passer du rôle de conjoint à celui de parent, ce qui modifie la dynamique de couple (relation conjugale). Les proches se disent anxieux face au risque de récidive (récidive) et certains présentent des malaises physiques comme des maux de tête et un manque d’énergie (santé). Les proches affirment n’avoir accès à aucun service et que le seul soutien dont ils bénéficie est celui de leur entourage (services). Conclusion : Le retour à domicile de la personne AVCL engendre diverses conséquences sur le quotidien des proches, ce qui affecte leur qualité de vie. / Introduction: Mild stroke clients are often independent in basic activities of daily living but may present subtle deficits that impact on complex activities and roles. The purpose of this study was to explore the perceived quality of life of close family members three months after the stroke client was discharged home. Method: Qualitative design based on a constructivist paradigm. Interviews were conducted with family members of mild stroke clients three months after discharge. An interview guide was used and the audio content was transcribed, followed by a content analysis. Results: Eight interviews were conducted (mean age 56.9 ± 9.2 years; men=2/8). Six essential themes emerged from the data. According to participants, mild stroke clients present sequelae that interfere with complex tasks (patient), increasing the burden on other family members who have to limit their personal activities (daily living). Spouses reported sometimes acting like a parent, which caused tensions in the relationship (conjugal relationship). Anxiety is related to the risk of stroke recurrence (relapse) and some family members present physical symptoms and a lack of energy (health). However, family members do not have access to services despite support from their relatives (services). Conclusion: The results of this exploratory study strongly suggest that even a ‘mild’ stroke has an impact on the daily lives of close family members and affects their quality of life.

Modélisation et résolution de problèmes généralisés de tournées de véhicules / Modeling and solving the generalized routing problems

Ha, Minh Hoang 14 December 2012 (has links)
Le problème de tournées de véhicules est un des problèmes d’optimisation combinatoire les plus connus et les plus difficiles. Il s’agit de déterminer les tournées optimales pour une flotte de véhicules afin de servir un ensemble donné de clients. Dans les problèmes classiques de transport, chaque client est normalement servi à partir d’un seul nœud (ou arc). Pour cela, on définit toujours un ensemble donné de nœuds (ou arcs) obligatoires à visiter ou traverser, et on recherche la solution à partir de cet ensemble de nœuds (ou arcs). Mais dans plusieurs applications réelles où un client peut être servi à partir de plus d’un nœud, (ou arc), les problèmes généralisés qui en résultent sont plus complexes. Le but principal de cette thèse est d’étudier trois problèmes généralisés de tournées de véhicules. Le premier problème de la tournée sur arcs suffisamment proche (CEARP), comporte une application réelle intéressante en routage pour le relevé des compteurs à distance ; les deux autres problèmes, problème de tournées couvrantes multi-véhicules (mCTP) et problème généralisé de tournées sur nœuds (GVRP), permettent de modéliser des problèmes de conception des réseaux de transport à deux niveaux. Pour résoudre ces problèmes, nous proposons une approche exacte ainsi que des métaheuristiques. Pour développer la méthode exacte, nous formulons chaque problème comme un programme mathématique, puis nous construisons des algorithmes de type branchement et coupes. Les métaheuristiques sont basées sur le ELS (ou Evolutionary Local Search) et sur le GRASP (ou Greedy Randomized Adaptive Search Procedure). De nombreuses expérimentations montrent la performance de nos méthodes. / The Routing Problem is one of the most popular and challenging combinatorial optimization problems. It involves finding the optimal set of routes for fleet of vehicles in order to serve a given set of customers. In the classic transportation problems, each customer is normally served by only one node (or arc). Therefore, there is always a given set of required nodes (or arcs) that have to be visited or traversed, and we just need to find the solution from this set of nodes (or arcs). But in many real applications where a customer can be served by from more than one node (or arc), the generalized resulting problems are more complex. The primary goal of this thesis is to study three generalized routing problems. The first one, the Close-Enough Arc Routing Problem(CEARP), has an interesting real-life application to routing for meter reading while the others two, the multi-vehicle Covering Tour Problem (mCTP) and the Generalized Vehicle Routing Problem(GVRP), can model problems concerned with the design of bilevel transportation networks. The problems are solved by exact methods as well as metaheuristics. To develop exact methods, we formulate each problem as a mathematical program, and then develop branch-and-cut algorithms. The metaheuristics are based on the evolutionary local search (ELS) method et on the greedy randomized adaptive search procedure (GRASP) method. The extensive computational experiments show the performance of our methods.

Intégration de systèmes d'acquisition de données spatiales et spectrales haute résolution, dans le cadre de la génération d'informations appliquées à la conservation du patrimoine / Integration of high resolution spatial and spectral data acquisition systems for monitoring purposes in cultural heritage applications

Simon Chane, Camille 26 March 2013 (has links)
Cette thèse s'intéresse au recalage de données issues de capteurs 3D et multispectraux pour l'étude du patrimoine.Lorsque l'on étudie ce type d'objet, il y a souvent peu de points saillants naturels entre ces jeux de données complémentaires. Par ailleurs, l'utilisation de mires optiques est proscrite.Notre problème est donc de recaler des données multimodales sans points caractéristiques.Nous avons développé une méthode de recalage basé sur le suivi des systèmes d'acquisition en utilisant des techniques issues de la photogrammétrie.Des simulations nous ont permis d'évaluer la précision de la méthode dans trois configurations qui représentent des cas typiques dans l'étude d'objets du patrimoine.Ces simulations ont montré que l'on peut atteindre une précision du suivi de 0.020 mm spatialement et 0.100 mrad angulairement en utilisant quatre caméras 5 Mpx lorsque l'on numérise une zone de 400 mm x 700 mm.La précision finale du recalage repose sur le succès d'une série de calibrations optiques et géométriques, ainsi que sur leur stabilité pour la durée du processus d'acquisition.Plusieurs tests ont permis d'évaluer la précision du suivi et du recalage de plusieurs jeux de données indépendants; d'abord seulement 3D, puis 3D et multispecrales.Enfin, nous avons étendu notre méthode d'estimation de la réflectance à partir des données multispectrales lorsque celles-ci sont recalées sur un modèle 3D. / The concern and interest of this PhD thesis is the registration of featureless 3D and multispectral datasets describing cultural heritage objects.In this context, there are few natural salient features between the complementary datasets, and the use of targets is generally proscribed.We thus develop a technique based on the photogrammetric tracking of the acquisition systems in use.A series of simulations was performed to evaluate the accuracy of our method in three configurations chosen to represent a variety of cultural heritage objects.These simulations show that we can achieve a spatial tracking accuracy of 0.020 mm and an angular accuracy of 0.100 mrad using four 5 Mpx cameras when digitizing an area of 400 mm x 700 mm. The accuracy of the final registration relies on the success of a series of optical and geometrical calibrations and their stability for the duration of the full acquisition process.The accuracy of the tracking and registration was extensively tested in laboratory settings. We first evaluated the potential for multiview 3D registration. Then, the method was used for to project of multispectral images on 3D models.Finally, we used the registered data to improve the reflectance estimation from the multispectral datasets
