Larmbolagets webbplats : En studie om skapandet av en tillgänglig och användbar webbplats

This paper accounts for the work with a website for a company whose real name will not be disclosed in the text of this paper. Instead, they have been assigned the fictitious name Larmbolaget, which can be translated as ?The Alarm Company?.During our work with Larmbolaget?s website, we consulted a selection of accessibility guidelines from the Web Content Accessibility Guidelines (WCAG) 2.0, developed by a working group within the World Wide Web Consortium, as well as a number of design principles and heuristics outlined in this paper. We also conducted several usability tests on users from our intended target group. All the measures taken were an effort to ensure that Larmbolaget?s website be as accessible and usable as possible.Our conclusion is that the resulting website does comply with the accessibility guidelines and design principles described in this paper, and thus we consider it to be accessible and usable to a wide range of users, including those with disabilities..

KASAM, betyg och stress : En undersökning om sambandet mellan KASAM, attityd till betyg samt upplevd stress hos gymnasieelever

The purpose of this study was to investigate the relation between SOC, attitudes towards grades, and perceived stress levels among adolescents, and whether there was any difference in this relation between gender. The first research hypothesis was: "there is a gender difference to the degree of SOC, attitude to grades, and perceived stress level". The second was that "SOC and attitude to grades, predict stress in adolescents". To answer these hypotheses, a questionnaire survey was carried out among upper secondary students, 95 boys and 89 girls. The result of the analysis showed a significant difference between the gender.

Goodwill och Marknaden: En studie av relationen mellan goodwillnedskrivningar och investerare

Following the implementation of IFRS with yearly impairment tests, the question of correlations and causalities between impairments and investors? decision making is gaining interest in academia. This essay will study the relationship between significant goodwill impairments, communicated on the Nasdaq OMX Stockholm webpage between the years 2005-2009, and the impact those announcements have had on investors? decision making. Furthermore, the causality behind the impairments will be in focus.

Identitetsskapande på Internet : En kvalitativ studie om det sociala nätverket Facebook

As computerized communication and the Internet have evolved, the possibility to express and affirm one?s identity in new ways has also been created. Facebook, which has taken a leading role among the social fora on the Internet and succeeded worldwide, is my choice of study due to the number of people that actively choose to present themselves on it. The purpose of this thesis is to study the identity construction on Facebook through the activities a member partakes in, as well as how the presentation of oneself is written and if it is a result of a self-reflective process of the individual.The rationale for the qualitative study has been personal interviews in order to get an insight into how the individuals use and present themselves on Facebook and - in the interaction with others ? how they construct their own identity. My hypothesis has been that we, in the interaction with others, have a great possibility to create and understand our own identities. The study results show that identity formation is a constant process and that it is indeed a self-reflective project.

Uteblev effekterna av 9/11? En analys av förändringen inom EU:s samarbete mot terrorism utifrån historisk institutionalism

In 1992, the European Union began institutionalizing the cooperation against terrorism within the EU structure. Since then, this cooperation has gone through a number of changes. From a historical institutionalistic point of departure we explain these changes by identifying sources of institutional resilience and institutional change. Based on these results, we were able to pose hypotheses of when and what category of change was most likely to take place.The results show that the cooperation against terrorism within the EU was most likely to remain stable because of strong sources of institutional resilience. If change would occur through an increase in the sources of institutional change, it was most likely to be of a less extensive category.

Mobbning - ett groupthink-fenomen? : En gruppsykologisk fördjupning av mobbning

The purpose of this essay was to examine and shed light on bullying as a groupprocess, a social phenomenon taking place in a school setting, to increase the understanding of the phenomenon. A theoretical overview of the litterature on bullying was made to investigate bullying and to give the reader a view of the researchfield. A total of 77 articles was studied. With the intention of studying bullying from a groupsychology perspective a metaanalysis was performed discussing groupphenomenon such as rolebehavior, responsibility, cohesiveness and norms in comparison to bullying episodes.Stemming from this analysis the question whether bullying can be view as a response to groupthink emerged. This question also constituted the secondary aim of this thesis.

Modellering av rotationssystem

This master thesis was conducted during the spring of 2014 at Atlas Copco Rock Drills AB in Örebro. The purpose of the thesis was to develop a simulation model of the rotation system for a hydraulic rock drill. In the future, the model will be used to investigate the phenomena called ?jerky rotation?. In order to validate the simulation model a test bench was designed and tests were made.

Mixture and single-compound toxicity using Daphnia magna : comparisons with estimates of concentration addition and independent action

Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.

Kalvutdragaren - en hjälpande hand? :

The calf extrator?s function has been studied, through measuring traction and how this varies in different situations, in comparison with corresponding manual traction situations. This was done against the background that excessive force at assisted calvings at dystocia can mean life threatening damages on the calf such as grave acidosis, vertebral fractures, femur fractures and rib fractures. The calf extractor has earlier been measured to pull with greater force than the established maximum force of ?two strong men?.

When does the protein profile in milk normalize after antibiotic treatment against clinical mastitis?

Concentration of protein in bovine milk is one of the most significant milk quality parameters, to a large extent determining the price for milk to the producer. Mastitis is a common disease among dairy cows, negatively affecting not only milk yield but also milk protein composition. Milk from mastitic cows tends to have lower cheese yield, negatively affected processability properties and sensory quality, due to changed protein quality and composition. Poorer milk protein quality would have an economically negative impact on dairy industry. Only few studies have investigated the short term effects of mastitis on milk protein composition.

Påverkan av skogsbrand på litiska arkeologiska fynd ? experimentell simulering av brand

This is a paper about the effects from smoldering fire on lithic objects from an archaeological view. The introduction gives the background to this paper, a short orientation to forest wildfires and why the work is limited to: flint, quartz, quartzite and slate. Material and methods describes the stone materials and the setup that was used in the temperature logged tests with three replications for each type of material. The fuel in the burnings was peat on a bottom of sand. Flint showed a more drastic effect from heat compared with the other materials. Slate seems to have greater tendencies to change to darker colour and luster at lower temperatures than the other materials.

Den uteblivna kommunikationen : - Som knäcker dig

Our study illustrates health communication in order to find out how widespread the knowledge is about osteoporosis and how to reach out with health information to the public. Our essay was conducted through quantitative surveys, which included 402 respondents. This in order to highlight the prevailing uncertainty about the public disorder osteoporosis, which is common in Sweden. We wish to examine trough which channels our respondents choose to collect their health information. The thesis framework includes theories such as McGuire?s ProcessingTheory, Agenda setting, Two-step hypothesis and Diffusion of innovation. Through these theories, we analyzed our empirical data that emerged. The results showed that our respondents had very low knowledge of osteoporosis, although theyshowed interest for health information. The results also showed that respondents were consistent intheir actions regarding which channels they came to turn to. They prefered their health informationfrom news papers and family, friends and work colleagues. When asked where they got their information from, the respondents answered mostly from family, friends and work colleagues, followed closely by newspapers. This shows that respondents are more receptive to informationfrom the channels of their own choice. The results also showed that the propensity to change behavior increases with the age of the respondents..

"Hur känd kan jag bli på fem veckor?" : En studie om distribution av musik via Internet.

Internet and the digital channels for distribution have meant big changes for the musicindustry. The physical record that has been symbolising this market for a long time is slowlybeing replaced by digital based music. The technical progress during the last ten years has ledto a democratization of music production. The amateur musicians of today can produce highquality music on their laptops and later distribute it via free music sites. MySpace andYouTube are two of the biggest sites for this free distribution and is therefore my main choiseof study.The purpose of this essay was to find out how and if these changes have made a difference formusicians without a record deal to reach an audience by themselves.

Att hantera sömmar i interaktiva system

The purpose of this paper is to examine how seams in an interactive system should be managed. Seamsin this study refer to the boundaries that arise when users move between for example differentsoftware, products or positioning systems. These seams are a cornerstone of the relatively unexploredarea called seamful design, which is based on that users can avail highlighted seams through activeparticipation in the use of a system. To analyze this area, seamful design is applied to the developmentof an interface of a smoothie vending machine. This smoothie machine thus provides the analyzedinteractive system, which the research questions are applied to as well as answered by.
