The aim of this thesis is to study the possibility of the existence of a specialist in bone tools manufacturing during the Mesolithic. The thesis describes the climate during the Mesolithic, argues for an experimental approach, and describes social organization in hunter-gatherer-groups and the processes behind cultural transmission. It also gives some examples of excavation sites in Scandinavia. An experiment simulating a teaching situation is made, in addition to the theoretical information, with the intent to explore how advanced the crafting of bone really is. The physical result is then studied and documented.

Design principles are usually used by interaction designers to help creating a user friendly design by making the designer think about the different aspects of the design. These design principles has been further developed since they emerged in the 1990s, and today they're often used in the field of interaction design. By using the design principles, bad design can be avoided and the frustration of the user reduced. Design patterns is described as structural and behavioral characteristics to improve the environment in user interface amongst other areas. These characteristics could make things easier to understand or improve their appearance, they make tools more usable.The purpose with this essay is to identify design guidelinesto be used by developers when designing surveillance systems.

In Sweden there are many kinds of effort given youths with behavioral problems, one is institutional care. International research display a varying kind of results from this type of treatment. The aim of this study is to examine and illustrate which central components that results in positive treatment, but also starighten important components in KBT. On the basis of research results, important components for positive treatment have been illustrated as; the therapeutic relationship, the integrity of treatment, prosocial-contacts, positive climate in treatment, the continual of treatment, how to bring treatment to an end, the responsivity principle-the principle of need-the risk principle, learning and KBT.  Research also aims to investigate whether these components could be identified in the daily work of youth treatment on institution. This through a qualitative approach including six interviews held with staff working in treatment facilities.

The Disney princess line includes nine films, in our study we have extended this line to include the latest three films from Walt Disney Pictures that follow the same pattern. These films are Tangled (2010), Brave (2012) and Frozen (2013). We have conducted our study using the same method used by England, Descartes and Collier-Meeks (2011) in their study of the first nine films, starting with Snow White and the Seven Dwarfs produced in 1937 to Princess and the Frog from 2009. A quantitative study was executed where we focused on gender role portrayal, the main characters behavioral characteristics and performed rescues. We applied the following theories to our result; the Social Constructivism, Laura Mulvey?s theory of the Male Gaze, Michel Foucault?s theory of power and discourse, intersectionality and Claude E.

The media arena is becoming more and more crowded by various brands and different commercial messages. At the same time, consumers learn how to screen marketing communication and their cognitive ad filters enable them to avoid message elaboration. Thus, new thinking and new communication executions are required in order to surprise the consumers and break through the clutter. In the present study, we have investigated how the choice of media affects attention, memory and several communication effects that the ad can generate in the short as well as in the long term. The study is conducted on a well-known brand within a low-involvement product category.

The purpose of the study was to describe the nurse´s role and experiences aroundpreparation of children in front of peripheral venous catheter (PVC) placement andblood draw. The study used a descriptive design with qualitative approach and wasperformed on a pediatric clinic in Sweden. Semi-structured interviews were performedwith seven nurses of whom the first was a pilot interview, which was included in theresult. The recruitment of nurses was made by a purposeful sampling, maximumvariation sampling, with help of the quality coordinator of the pediatric clinic. Thecollected data was analyzed with the manifest qualitative content method.

By conducting a text analysis this study analyzes possible similarities in the portrayal of story characters between historical Norse myths and contemporary film productions. The chosen historical texts are two stories from Norse mythology which render a myth about Thor and a giant named Hrunge as well as the myth Trymskvädet. The selected movies are two of the comic company Marvel?s productions about super heroes ? Thor and The Avengers. Different categories that this study compares are how the characters are defined by their possessions or artefacts, the actions and the choices which the characters make, and also how their relations, roles and origins are being portrayed.

Metakognitiva processer och förmågor innefattar bland annat människans förmåga att reflektera över sin egen kunskapsnivå och minneskapacitet, och att utifrån detta till exempel kunna reglera tid och inlärningsstrategier vid inlärningssituationer. Kännetecknande för en person som räknas till att vara expert inom en viss domän är bland annat att denne anses kunna övervaka sin kunskapsnivå på ett korrekt sätt. Denna studie undersöker om personer med stor domänkunskap uppvisar en större förmåga till metakognitiv övervakning än vad personer med sämre domänkunskap gör. Aktuell kunskapsdomän i denna studie är deklarativ kunskap kring fotboll, och fotbollsspelare och ledare rekryterades som försöksdeltagare. Förmågan till metakognitiv övervakning mättes med hjälp av mätteknikerna Assessment of Cognitive Monitoring Effectiveness (ACME) och Metacognitive Knowledge Monitoring Assessment (KMA), där försöksdeltagarna i samband med att ett kunskapstest genomförs får avgöra vilka frågor de tror sig kunna eller inte kunna svaret på.

The design process of an interaction design student is mostly collaborative and computer oriented. Based on this, it?s hard to believe that we have not yet found a tool that will facilitate our needs. With this in mind, which elements do we need to promote collaboration in a virtual design process? This thesis will include design processes, collaboration, creativity and virtual awareness, amongst others.

This master thesis covers the development of an automatic tuning process for the existing speed controller for drive systems. The drive systems are resonant two-mass systems where a motor is used to drive a load connected by a shaft. The developed method relies heavily on system identification and the construction of a complete mechanical model of the process. With this approach, the common problem with poor load speed control that derives from measuring only the motor speed can be addressed and solved for a majority of such processes.The automatic tuning method has along with general test functions been implemented in a complete tool for automatic tuning, testing and performance evaluation and reporting for drive systems..

There is much literature covering strategic change under different circumstances but very little concerning how companies act strategically under sudden and radical changes to market conditions. Based on three different events (the terrorist attack in the USA September 11th 2001, the Tjernobyl accident April 26th 1986 and the Islamic revolution in Iran 1979) with such radical changes as a result we chose three companies that were affected (SAS, Asea Atom and Atlas Copco). The result of the events that were studied in this thesis is extremely unusual to their character. The events themselves were sudden and of a temporary nature but the results were long term changes of market conditions. Through personal interviews the authors have tried to establish how the companies have perceived the events and how the top management has strategically handled the situation.

The purpose of this essay was to examine the packaging design´s communications related to the colloquially brand's symbolic capital and how they became meaningful through experience and perceptions that led to the identification processes in the consumer society. There were eight interviews of snuff users who became my main collections materials. My theoretical framework was discourse psychology´s emphasis on language and Bourdieu´s concept provided important tools in the analysis of the material.I could highlight that packaging design and the brand had influenced the informants and given them symbolic beliefs and what it meant to sniff a certain brand. Color, brand awareness and price were crucial in choosing where the informants attributed themselves the cans symbolic values to their identity. It could be inferred high and low status perceptions based on stereotypes in the design itself..

Background: Stroke is one of the leading causes for longlasting sequelae, among themloss in cognitive function, like aphasia. Aphasia effects the patients ability to understandand express themselves in speaking and writing. To be able to reach a good level of care,the careproviders and patients ought to have the same goals and values. This requires agood communication between the careproviders and patients. Which can be problematicfor the caregivers when they don't feel secure in their way of getting close to these patients.Aim: The purpose of this study was to illuminate caregivers experience of caring forpatients with the diagnosis aphasia following stroke.Method: This is a literature study where nine studies, with qualitative design, has beenanalyzed and compiled.

Universal Design is a well established methodology with the fundamental purpose of designing products to be usable for as wide audience as possible, without the need of special adjustment to suit the individual. In this essay, Universal Design has had a clear influence in both the process and the result. The choice to use Universal Design as methodology in this usability evaluation, has essentiallv to do with the target audience.As a part of the design process of MyTobii C8 has Tobii Technology ask for a usability evaluation. MyTobii C8 is an 8" touch screen computer with a windows based operating system which will initiate the software MyTobii C-Series Control. MyTobii C-Series Control is the control panel for MyTobii C8, whose interfaces constitute the platform for various modificarion of the unit.

Syftet med denna studie är att undersöka vilka orsaker det finns för ungdomar som avsluter sina studier på gymnasiet och hur studie- och yrkesvägledare följer upp ungdomarna efter avbrottet. Följande frågeställningar har formulerats: Vilka är de faktorer som gör att ungdomar avbryter sin gymnasieutbildning? Hur ser processen ut från att ungdomarna bestämmer sig för att hoppa av och till att den gör det? Hur arbetar studie- och yrkesvägledare med uppföljning av ungdomar efter avhopp från gymnasiet? Vi har använt oss av kvalitativ metod och genomfört fyra intervjuer med studie- och yrkesvägledare. Tidigare forskning finns kring orsaker till studieavbrott, hur man ska motverka avbrott, vilka konsekvenser avbrotten har och hur studie- och yrkesvägledare arbetar med det. För att analysera det empiriska materialet har teorierna Careership, Social Cognitive Career Theory (SCCT) och Gottfredsons teori. Resultatet som vi fick fram var att det fanns olika orsaker till studieavbrott, de vanligaste var felval, påverkan av omgivning och mobbning. Ungdomarna befinner sig i en svår situation under valet och behöver stöd från omgivningen.
