Onlinespel en upplevelse : en kvalitativ undersökning av ungdomars attityder om onlinespel

Moradi, Armin January 2010 (has links)
AbstractTitle: Onlinegaming – A qualitative study of young people's attitudes about online gaming(Onlinespel – En Kvalitativ undersökning av Ungdomars attityder om onlinespel)Number of pages: 34 (35 including enclosures)Author: Armin MoradiTutor: Else NygrenCourse: Media and Communication Studies CPeriod: Autumn 2009University: Division of Media and Communication, Department of Information Science,Uppsala UniversityPurpose/Aim: The purpose of my thesis is that from a social perspective to examine and discussyoung people aged 16-18 vision of online gaming. Why online games are so popular and to see ifthe stereotype is a reality among young people in their late teens ..I also have a secondary purpose where I want to explore the social function of online games have,and what or what needs it fills in young people's everyday lives.Material/Method: The main method used in this essay has been qualitative group interviewswith 17 high school students. The result from these interviews has then been analysed usingseveral theories, Uses and gratification theory, Socialinteraction theory, Interactivity theory andmedium theory.Main results: The compilation of collected my results have shown that young people makeextensive use of online gaming pastime and to socialize with each other both virtually andphysically. Online gambling has on young people an entirely different meaning than it does forolder generations.For young people online is as natural as watching TV is for the oldergenerations.There are gender differences in perception of online games but it is not at all in the same highdegree as can be expected, the differences were minimal. The participants in my interviews havealso made an association exercise in which I presented as the words of 15-20 seconds to describeother words. Most replied to the word "Homework" that it was "boring" and the word "computergames" was the most frequently used word "fun".Keywords: Uses and gratification theory, Socialinteraction theory, Interactivity theory , Mediumtheory, Online gaming,

Redovisningens användare och änvändning : Externredovisning ur ett småföretagsperspektiv

Petersson, Eva, Söderberg, Malin, Kviberg, Rebecca January 2007 (has links)
Ofta fokuseras det på större företag i undervisningen, men verkligheten är den att de flesta företag i Sverige är små eller medelstora. Det finns olika definitioner av vad ett småföretag är, men ingen är mer rätt än någon annan och i denna uppsats kommer EU:s definition att användas. Alla företag, stora som små, har någon/några som vill ta del av företagets ekonomiska information. De små företagen har oftast inte lika många intressenter som de stora företagen, och därför är det sannolikt att de inte behöver en lika komplicerad och detaljerad redovisning. Dessa mindre företag har under en längre tid haft samma regelverk som de större, men BFN, IASB och lagstiftare har påbörjat ett förenklingsarbete av redovisningsreglerna. För att kunna vara säker på att de nya reglerna verkligen fyller sitt syfte är det viktigt att de uppfyller de krav som företagen och användarna av redovisningsinformationen har. Det är därför viktigt med ytterligare forskning inom området då man fortfarande har relativt lite kunskap om vilka som använder sig av redovisningen och hur. Vi vill med denna uppsats skapa förståelse för vilka småföretagen ser som huvudanvändare av externredovisningen samt hur denna används. Vi vill vidare undersöka om småföretagens syn på huvudanvändarna skiljer sig från de studier och den litteratur som finns på området. För att samla in vårt empiriska material har vi använt oss av telefonintervjuer. Vi har intervjuat 36 småföretag i Jönköpings län, och av respondenterna är hälften byggföretag och den resterande hälften är tjänsteföretag. I denna uppsats har vi kommit fram till att majoriteten av de allra minsta företagen ser upprättandet av externredovisningen som ett nödvändigt ont, och att betydelsen av den har en tendens att öka när antalet anställda och antalet ägare ökar. Detta kan tänkas bero på att kunskapen inte finns i de mindre företagen. Den användning småföretagen ser att de har av externredovisningen är för uppföljning, vid planering, för likviditetsmätning, som beslutsunderlag och för att informera personalen och företagsledningen. Utifrån vår undersökning har det framkommit att småföretagen ser ägare/styrelsen/VD, banken och skattemyndigheten som de främsta huvudanvändarna. Vårt resultat stämmer till stor del in på tidigare studier, men vissa skillnader finns. Vi har även fått andra svar så som kunder, revisorn, leverantörer, konkurrenter och övriga. Revisorn är ett svar som kan diskuteras då ingen från den litteratur vi använt tagit upp detta, men även för att denne i praktiken inte använder sig av redovisningen så som till exempel banken. Slutligen kan det konstateras att storleken har betydelse, då vi kan se skillnader mellan de allra minsta småföretagen och de största. / In most cases within educational fields it is the bigger companies which get most attention, though infact in Sweden there are the small and medium size entities which are of larger number. There are several definitions what a small enterprise stands for and how to define it. Therefore it is hard to say that one definition is better than another, however in this thesis EU’s definition will be used. All companies no matter size have some stakeholders who want to take part of the financial state-ments of the company. The smallest companies have most of the time not that many users/shareholders as the bigger companies and for that reason it is likely that they do not need an equally complicated and detailed accounting. These smaller companies have during some time had the same regulatory laws as the large companies, nevertheless BFN (Bokföringsnämnden, the Swedish government’s accounting experts), IASB and legislates have begun to work with facilitation of the accounting regulatory. To assure that the new rules really fulfil their purpose it is essential that they accomplish the requirements which the companies and users of the accounting have. Thus it is necessary with further research within this area since there is still moderately little knowledge regarding who the users of the accounting are and how they use the information. Our aim with this thesis is to create understanding of whom the small enterprises see as their main user of accounting and how it is used. Further we want to investigate if a small enterprise’s view of a user differs from already existing studies and literature concerning this topic. To collect our empirical material we have chosen to conduct telephone interviews. We have interviewed 36 small enterprises within the Jönköping region in Sweden. Half of the selected companies consist of enterprises from the construction sector and the other half from the service sector. With our research we are able to conclude that the majority of the smallest companies see the accounting as a complex performance that has to be done although the purpose of it has a tendency to enhance along with the number of employees and owners. This could be the consequence of lack of knowledge among the smaller companies. The small enterprises consider their main use of the accounting to be planning, to follow-up, to measure liquidity, basic data for decision making and to provide employees and management with information. On the basis of our study it has emerged that the small enterprises see owner/management/CEO, the bank and the tax authority as the major users. Our result corresponds to some extent with ear-lier research, but there are differences as well. Among our responds we have obtained answers like customers, the accountant, suppliers, competitors and others. It can be discussed why the accountant was mentioned due to none in the literature we have been using brings this up, but also because of that the accountant does not use the accounting in the same way as for example the bank. To conclude we can state that the size does matter when we are able to see differences in the result between the smallest companies and slightly bigger ones.

Little Sewickley Creek: The Redesignation Process of a High Quality Stream to an Exceptional Value Stream

Reinhart, Nathan Todd 22 April 2013 (has links)
The Pennsylvania Department of Environmental Protection has set designated uses for all of the 83,000 miles of waterways based on their quality. Only the highest quality streams are afforded the highest protection with a High Quality (HQ) or Exceptional Value (EV). Little Sewickley Creek is designated as a High Quality-Trout Stocking Fishery and may warrant redesignation as an Exceptional Value waterway. The aim of the study was to provide technical data on the stream to support an EV reclassification. The report has compiled previous data and collected new data in order to file a formal petition to the PA DEP. The petition process involves consideration of physical, chemical, biological data on the stream, along with the land use of the watershed. The report gives an example of a stream located just outside of Pittsburgh that has extremely high biodiversity and deserves the highest protection to preserve it for future generations. / Bayer School of Natural and Environmental Sciences; / Environmental Science and Management (ESM) / MS; / Thesis;

Det sociala intranätet ur ett mottagarperspektiv : – En kvalitativ studie av Skellefteå kommuns nya sociala intranät / The social intranet from a receiver perspective : - A study of Skellefteå Municipality new social intranet

Silfver, Emma January 2013 (has links)
För att en organisation ska fungera måste kommunikationen fungera, för många organisationer och företag har intranätet blivit en av de primära kommunikation- och informations kanaler. Ett intranät stöder främst nedåtriktad information och fungerar som en informationsportal men den tekniska utvecklingen går framåt och nya höjder nås för vad som är tekniskt möjligt att göra. Skellefteå kommun är en organisation som valt att förnya sitt intranät och skapa ett nytt socialt intranät, det sociala intranätet skiljer sig från sin föregångare genom att det inte enbart består av statisk information utan det är kommunikativt. Syftet med den här studien är att undersöka vilken uppfattning anställda inom Skellefteå kommun har om organisationens nya sociala intranät samt hur de använder det. Materialet till studien samlades in genom sex semistrukturerade intervjuer. Teoribildningar som är centrala för studien är blanda annat socialt intranät och eftersom denna studie tar sin ansats ur ett mottagarperspektiv används användningsmodellen då den försöker klargöra hur människan fungerar gentemot medierna. Resultatet visar att det förekommer olika uppfattningar om organisationens nya sociala intranät, majoriteten av intervjupersonerna har en reserverad inställning till det nya intranätet. Resultatet visar även att det nya intranätet primärt används för att söka information och när det kommer till hur det nya sociala intranätet uppfattas som socialt kommunikationsforum kunde ingen av respondenterna ge ett tydligt svar då de uppgav att det inte förts någon diskussion om möjligheten att kommunicera med hjälp av det nya intranätet. / For an organization to function the communication needs to function, for many organizationsand enterprises the intranet have become one of the primary communication and information channels. An intranet supports mainly downward information and acts as an information portal but the technology is constantly evolving and we reach new heights of what is technically possible to do. Skellefteå municipality is an organization that has chosen to renew its intranet and create a new social intranet, the social intranet differs from its predecessor in that it not only consists of static information, it is also communicative. The aim of this study is to investigate the perception that the employees in Skellefteå municipality has on the organization's new social intranet and how they use it. The study´s empirical base is gathered through six semi-structured interviews. Theories that are central to the study are inter alia: social intranets and since this study takes its approach from a receiver perspective the Uses and Gratification perspective is used since it seeks to clarify how humans function in relation to the media. The results show that there are different perceptions of the organization's new social intranet, the majority of the interviewees have a reserved attitude to the new intranet.The results also shows that the new intranet is primarily used for searching information, and when it comes to how the new social intranet is perceived as a social communication forum, none of the respondents could give a clear reply as they stated that there been no discussion of the possibility of communicating through the new intranet.

Organic Residue Analysis and the Earliest Uses of Pottery in the Ancient Middle East

Gregg, Michael William 18 February 2010 (has links)
In this dissertation, I discuss the role of organic residue analysis in identifying economic activities and subsistence practices associated with the first uses of pottery in the Middle East, and present the results of my analyses of 280 potsherds recovered from 22 Neolithic and early Chalcolithic settlements dating between 7300 and 4300 cal BC. The adoption of pottery vessels in the early agricultural villages and pastoral encampments of the Middle East was not a uniform phenomenon, with this new technology not immediately of benefit, apparently, to all human groups. Results of my analyses have demonstrated that ‘conventional’ solvent extraction and alkaline hydrolysis techniques have limited utility in the recovery of diagnostic organic compounds from pottery from early ceramic horizons in the Middle East (Gregg et al. 2007), and that increased yields can be achieved through the use of a microwave-assisted liquid chromatography protocol (Gregg et al. 2009; Gregg and Slater in press). My research has established that there is greater diversity in the fractionation of stable carbon isotopes associated with the synthesis of fatty acids in domesticated animals than has previously been reported. In many instances, the ranges of modern isotopic values that have been used to categorize animal fats in archaeological potsherds in northern Europe cannot distinguish between the ∂13C ratios of ancient dairy residues and carcass fats of ruminant and non-ruminant species in central Europe or the Middle East (Gregg et al. 2009; Gregg and Slater in press). In light of these results, I evaluate the diagnostic potential and limitations of different methodological approaches in the recovery and characterization of organic residues, and propose a series of measures that will allow more confident categorization of the substances in early pottery vessels from the Middle East. I also make a number of recommendations for archaeologists considering the use of organic residue analysis, and suggest some practical ideas on how to develop the degree of confidence necessary to assess the methods used in acquisition of molecular and isotopic data, and ultimately, to evaluate the adequacy of the analytical criteria used to address specific archaeological research questions.

Self-Presentation and Social Interaction on Blogs: A Structural Equation Modeling of the Uses and Gratifications of Blogging

Tian, Qing 21 April 2009 (has links)
This study explored why individuals write personal blogs and the influences of blogging on their lives. Four structural equation models that specified the social and psychological process of blogging were tested in this study. The models included four major components: personal characteristics, blogging motives, blogging behaviors and blogging social outcomes. A total of 412 bloggers recruited online completed the survey questionnaire. A factor analysis revealed nine salient motives for writing personal blogs: self-documentation, information sharing, entertainment, emotion regulation, communication with existing friends, formation of new friendships, identity exploration, pass time and self-presentation. Significant associations between these motives and demographics, including gender, age and education, were also identified. The results of the structural equation modeling suggested that public self-consciousness was positively related to the self-presentation motive, which was in turn positively related to self-presentation in blogs. In the same vein, social anxiety was positively related to the motive to form new friendships, which in turn was positively related to the number of new friends made via blogs and the quality of new friendships. Social anxiety was found to be negatively associated with the number of new friends made, the number of existing friends communicated with, and the quality of existing friendships maintained through blogs, but positively related to the quality of new friendships established via blogs. Self-disclosure was positively related to the number of new friends made, the quality of new friendships and the quality of existing friendships. The mediation effects of blogging motivations and self-disclosure on the relationships between social anxiety and blogging social interaction outcomes were also tested. The content analysis of the responses to an open-ended question indicated that the majority of the respondents believed that blogging had positively influenced their lives. The major benefits of blogging reported by the respondents included keeping in touch with family and friends, making new friends, improved social interaction, writing and thinking ability, expanded vision, emotional relief and social support, identity exploration, and documentation of daily life. Interpretations of the findings, and implications for understanding the social use of the Internet, were discussed.

Un entorno de aprendizaje y una propuesta de enseñanza de Simulación de Eventos Discretos con GPSS

Villarreal, Gonzalo Luján 30 September 2013 (has links)
La enseñanza en el área de simulación de eventos discretos requiere integrar una variedad de conceptos teóricos y ponerlos en práctica a través de la creación y ejecución de modelos abstractos de simulación, con el objetivo de recopilar información que pueda traspolarse hacia los sistemas reales. Para construir modelos, ejecutarlos y analizar los resultados de cada ejecución se utilizan herramientas de software cada vez más sofisticadas que permiten expresar los elementos de los modelos en términos de entidades abstractas y relaciones, y que recopilan gran cantidad de datos y estadísticas sobre cada una de estas entidades del modelo. GPSS es una de estas herramientas, y se compone de un lenguaje de programación por bloques y un motor de simulación que traduce estos bloques en distintas entidades del modelo. A pesar de que su primera versión data de 1961, GPSS es aún muy utilizado por profesionales y empresas, y es una de las herramientas más utilizadas para la enseñanza de simulación de eventos discretos por instituciones académicas de todo el mundo.  El avance de la capacidad de cómputo de las computadoras ha permitido incorporar una mayor cantidad de herramientas y funciones a las distintas implementaciones de GPSS. Mientras que esto representa una ventaja para sus usuarios, requiere también un cada vez mayor esfuerzo por parte de los docentes para enseñar a sus estudiantes a aprovechar todo su potencial. Muchos docentes e investigadores han buscado optimizar la enseñanza de simulación de eventos discretos desde múltiples ángulos: la organización del curso y la metodología de enseñanza, la creación de elementos de aprendizaje que ayuden a aplicar los distintos elementos teóricos, la generación de herramientas para construir modelos GPSS, y la construcción de herramientas para comprender el motor de simulación por dentro. En esta tesis se introduce una herramienta de software que permite construir modelos GPSS de manera interactiva, cuyo diseño fue pensado para integrar los elementos teóricos del curso con los objetos y entidades de GPSS. Esta herramienta también permite ejecutar estos modelos y analizar con alto nivel de detalle su evolución a través del tiempo de simulación, lo que permite a los estudiantes comprender cómo funciona el motor de simulación y cómo interactúan las distintas entidades entre sí. Se incluye también una propuesta de enseñanza basada en una fuerte participación de los estudiantes, que, por medio de esta nueva herramienta, les permite incorporar los conceptos más fácilmente. Esta propuesta de enseñanza fue puesta a prueba con alumnos del área de sistemas, quienes tomaron un curso que contiene los mismos elementos teóricos y prácticos de un curso tradicional, pero con una organización diferente. Entre los resultados logrados se destacan una reducción del tiempo requerido para aprender los conceptos de GPSS cercana al 50%, una mayor capacidad por parte de los alumnos para asimilar conceptos y derivar nuevos conceptos por sí solos, a partir de conceptos adquiridos previamente.

Slagfälten : slagfältsarkeologins möjligheter och begränsningar / The Battlefields : Possibilities and Limitations of Battlefield archaeology

Ekengren, Erik William January 2011 (has links)
This paper explores the theoretical and practical uses and limitations of battle-field archaeology. The author aims to paint a big picture of the subject of exca-vating, understanding and theorising about historical battlefields done every day by archaeologists. Its approach places much weight on a quantity of examples rather than exploring specific excavations in every detail, in an effort to give the reader an understanding about how battlefield archaeology works. It stresses the need for battlefield archaeology as a way of obtaining and securing impor-tant archaeological and historical information before it is lost to science. The author tries to evaluate the subject in a critical and pragmatic fashion in order to establish a clear understanding about the facts of battlefield archaeology.

‘News use’- Informative or Entertaining? : An empirical study of collage students’ motives for using news

Ghorui, Soumita January 2012 (has links)
Collage students’ news consumption has been a very popular research topic in media in pastfew years. But students’ involvement in news dissemination remained unnoticed andunexplored, especially in relation to democratic engagement. This study provides an overviewin this respect along with news consumption. The research reports the outcome of a surveyconducted among 124 Swedish college students, aged between 18 and 24, in spring 2012. Thestudy investigates college students’ news consumption and news dissemination of in terms ofmotives. The analysis suggests that motivations behind collage students’ news consumptionare independent of channels/media. Consumption motives appear to be similar betweentraditional and contemporary news media. Furthermore, news consumption and newsdissemination seem to be driven by completely different motives.
