Hur påverkas immersion i rollspel av framställandet av icke spelbara karaktärer? / How is immersion in roleplaying games affected by the portrayal of NPCS?

Nordenberg, Katarina, Johnsson, Karl-Kristoffer January 2022 (has links)
Emergent narrativ är narrativ som uppstår genom interaktion med spelet. Det har undersökts hur framställandet av icke-spelar-karaktärer har påverkat immersionen, d.v.s. hur mycket spelarna lever sig in i spelet, i ett sådant narrativ. En rollspelskampanj har skapats i två versioner. I den ena versionen varr orcherna platta, våldsamma karaktärer som framställdes med syftet att enbart fungera som fiender för spelaren. I den andra versionen mötte spelaren unika orcher som alla hade egna utseenden, personligheter och mål.  Resultatet tyder på att framställandet av NPC:erna är viktigt och att bra NPC:er har en positiv effekt på rollspelet, men att detta beroende på andra faktorer kanske inte är en absolut nödvändighet. Framtida arbete bör syfta till att undersöka vilka andra faktorer som kan påverka samt sätta arbetet i en bredare kontext. / <p>Det finns övrigt digitalt material (t.ex. film-, bild- eller ljudfiler) eller modeller/artefakter tillhörande examensarbetet som ska skickas till arkivet.</p>

The Digital Workplace - Integrating Chaotic Knowledge Processes

Åkerblom, Victor January 2012 (has links)
Genom fallet QlikTech ger denna uppsats en aktuell inblick i hur kunskapshantering kan hanteras i en kunskapsintensiv kontext. Medarbetare har i dag möjligheter att samarbeta inom olika interaktiva digitala miljöer för att hitta och dela med sig av kunskap och erfarenheter. Denna uppsats fokuserar på att undersöka hur digitala Communitys uppkommer, växer fram och integreras för att uppnå global kunskapsdelning inom organisationer. Detta ses som en framgångsfaktor för att ta vara på kunskapsintensiva utvecklingsföretags kretivitet och innovationskraft.Genom ett tolkande tillvägagångssätt, analyseras åtta semistrukturerade kvalitativa intervjuer med medarbetare på QlikTech för att undersöka hur olika informationssystem används för att stödja olika kunskaps- och kollaborationsprocesser. Intervjuerna kompletteras med observationer and dokumentanalyser för att nå djupare insikter.Resultaten tyder på att användare använder system med fördefinierade strukturer för att dokumentera officiell kunskap, och system med framväxande strukturer för informell dialog och samarbete. Olika system kompletterar varandra, då kunskap förs över mellan system. Gräsrotsinitierande informationssystem kompenserar för glappet mellan officiella IT-implementationer och sociala kommunikationsbehov.Teknologi och praktik utvecklas hand-i-hand. Då diskussioner, idéer, perspektiv och kontext kan upprätthålls i emergent social software platforms, t.ex. Salesforce.com, kan komplext problemlösande underlättas i datorstött samarbete. Dessa plattformar minimerar glappet mellan den formella och sociala kommunikationen inom communities of practice, vilket ger förutsättningar för organisatorisk lärande.På QlikTech växer digitala communitys fram organiskt över tid. Organisationer använder data- och text mining och relaterade teknologier för att brygga fragmenterade communitys för att uppnå kapacitet att nå isolerade kunskapskällor genom sökning. Organisationer kan lägga till sociala lager över dessa fragmenterade back-end-system, designade för att bilda övergripande gränssnitt mot användare som underlättar samarbete och driver på innovation inom arbetsplatsen. / This thesis provides contemporary insights how knowledge management can be approached by a knowledge-intensive organisation. Knowledge workers today have unprecedented means to collaborate in different spaces of knowledge sharing. By analysing the case of QlikTech, results indicate that knowledge management is an integral part of knowledge-intensive organisations.By adapting an interpretive approach, eight semi-structured qualitative interviews with employees at QlikTech are analysed to find out how different information systems support different knowledge and collaboration processes. The interviews are complemented by on-the-job observations and analysis of documents to reach deeper understanding.Results indicate that users use systems with predefined structures to document official knowledge, and systems with emergent structures for informal dialogue and collaboration. Different systems complement each other, as knowledge is transferred between systems. Grass root initiated information systems compensate for the gap between official technology implementations and the social communication needs.Technology and practice co-evolve. As discussions, ideas, perspectives and context can be sustained in emergent social software platforms, such as Salesforce.com, complex problem-solving can be enabled in computer-supported cooperative work. These platforms minimise the gap between the formal and social communication within communities of practice, which facilitates organisational learning.At QlikTech, digital communities emerge organically over time. Organisations can use data and text mining, natural language processing and information extraction technologies to bridge fragmented communities to gain the capabilities to access dispersed knowledge sources through search. Organisations can add a social layer of these fragmented back-end systems, designed for building cross-functional employee-facing communities that drive collaboration and accelerate innovation in the workplace.

The effects of short-term sea level rise on vegetation communities in coastal Mississippi

Andrews, Brianna Michelle 13 May 2022 (has links)
Salt marshes are important habitats that provide many ecosystem services, but they are susceptible to the impacts of sea level rise (SLR), often resulting in emergent vegetation loss. In areas with enough sediment input, marshes can keep pace with SLR by gaining elevation or through upland migration. However, salt marshes in areas with limited sediment input, such as the Grand Bay National Estuarine Research Reserve, often cannot keep pace with sea level rise. Additionally, the rate of SLR is increasing making it more difficult for marshes to keep pace. To assess the short-term response of marsh vegetation to sea level rise, percent cover, stem density, and elevation, data from 2016 to 2020 in four different marsh elevation zones were analyzed in this study. Results demonstrated that the four marsh elevation zones are responding disparately to SLR. These findings indicate that it is imperative to implement restoration plans to account for site variability to conserve these vital habitats.

Electronic Picturebooks: Do they Support the Construction of Print Knowledge in Young Emergent Literacy Learners?

Allison, Jean Caramanico January 2016 (has links)
This dissertation presents the results of an intervention study examining whether electronic picturebook applications on a tablet computer support the development of print knowledge in preschool age children in low literacy childcare environments. Print knowledge is one of the earliest literacy skills to develop and there is evidence that children who enter kindergarten without this skill are less likely to be reading on grade level two years later (Piasta et al., 2012; Whitehurst & Lonigan, 1998). Since print knowledge is so critical for later literacy development, it is important to make sure that all children acquire this capacity. The sample for this study consisted of 3 and 4 year old children who attended six low literacy classrooms in four childcare centers located in Delaware and Chester Counties. Classrooms were randomly assigned as either experimental or control. A tablet computer preloaded with interactive electronic picturebooks was added to the experimental classroom for children to interact with during free play. Teachers were told not to use the tablet for individual, small or large group reading and there were no other changes to the literacy environment. Children were allowed to play with the tablet as a free choice activity. There were no changes to the literacy environment of the control classrooms. A pre-test/post-design using the Get Ready To Read Screening tool measured changes in children’s print knowledge learning over the three month period of time in which the study was conducted. The quality of the literacy environment was measured at the beginning and end of the study. Additional data were gathered through teacher and family questionnaires and classroom observation. The frequency and duration of tablet use was also tracked. The results indicate that there were no positive significant differences in print knowledge from pre to post test. This indicates that the teacher is still the most critical component of the emergent literacy environment. / Educational Psychology

Towards Emergent Configurations in the Internet of Things

Alkhabbas, Fahed January 2018 (has links)
The Internet of Things (IoT) is a fast-spreading technology that enables new types of services in several domains, such as transportation, health, and building automation. To exploit the potential of the IoT effectively, several challenges have to be tackled including the following ones. First, the proposed IoT visions provide a fragmented picture, leading to a lack of consensus about IoT systems and their constituents. A second set of challenges concerns the environment of IoT systems that is often dynamic and uncertain, e.g. devices can appear and be discovered at runtime as well as become suddenly unavailable. Additionally, the in- volvement of human users complicates the scene as people’s activities are not always predictable . The majority of existing approaches to en- gineer IoT systems rely on predefined processes to achieve users’ goals. Consequently, such systems have significant shortcomings in coping with dynamic and uncertain environments. To piece together the fragmented picture of IoT systems, we sys- tematically identified their characteristics by analyzing and synthesizing existing taxonomies. To address the challenges related to the IoT envir- onment and the involvement of human users, we used the concept of Emergent Configurations (ECs) to engineer IoT systems. An EC consists of a dynamic set of devices that cooperate temporarily to achieve a user goal. To realize this vision, we proposed novel approaches that enable users to achieve their goals by supporting the automated formation, en- actment, and self-adaptation of IoT systems. / <p>Note: The papers are not included in the fulltext online.</p><p>Paper I in dissertation as manuscript.</p>

Capabilities Engineering:Promoting Change-Reduction and Constructing Change-Tolerant Systems

Ravichandar, Ramya 05 June 2008 (has links)
We propose a Capabilities-based approach for constructing complex emergent systems such that they are change-tolerant, and the development effort promotes change-reduction. The inherent complexity of software systems increases their susceptibility to change when subjected to the vagaries of user needs, technology advances, market demands and other change inducing factors. Despite the inevitability of change, traditional Requirements Engineering strives to develop systems based on a fixed solution. This is a mostly unsuccessful approach as evidenced by the history of system failures. In contrast, we utilize Capabilities — functional abstractions that are neither as amorphous as user needs nor as rigid as system requirements — to architect systems to accommodate change with minimum impact. These entities are designed to exhibit desirable characteristics of high cohesion, low coupling and balanced abstraction levels. Capabilities are generated by a two-phased process called Capabilities Engineering. Phase I mathematically exploits the structural semantics of the Function Decomposition graph — a representation of user needs — to formulate change-tolerant Capabilities. Phase II optimizes these Capabilities to conform to schedule and technology constraints. Results from an empirical evaluation of a real-world Course Evaluation System indicate, with statistical significance, that a Capabilities-based design is more change-tolerant than a requirements-based design. In addition, we observe that the use of the CE process inherently reduces change, otherwise generated, during the regular development effort. Empirical analysis on the change-requests of Sakai, a complex emergent system, supports this claim. Finally, we observe that the process of Capabilities Engineering assists in pre-requirement specification traceability by bridging the complexity gap between the problem and solution spaces. / Ph.
