Information overload is by no means a new concept, but has come to prominence the last decade. A generally accepted definition of the phenomenon does not exist. The main question in this master thesis is how to define information overload in order to create a connotative concept for information science. This thesis reviews the nature and causes of information overload, and considers possible solutions, both individual and technical, and their relevance to the information professional. The review of the results shows that researchers seldom or never give a legible definition of what the concept information holds.

Around 30,000 people in Sweden suffer stroke every year, out of which about 12,000 end up with language difficulties, aphasia. Behind every person with aphasia there are significant others whose lives are also affected. Studies of how aphasia affects the health of these people are few. The overall aim of the present study was to examine how significant others of people with aphasia perceive their life situation, and how their quality of life is affected by the illness of their partner. Spouses of people with aphasia were contacted through aphasia groups and the Swedish Aphasia Association.

Regulation of rivers by dams and reservoirs is a good example where anthropogenic impact could be considerable both in the local environment, but also has major implications upstream and downstream. This study was accomplished as a literature study of the river Nile, which is extremely important for water supply. The purpose of this study was to investigate the consequences of the construction of the Aswan High Dam, to obtain a consistent flow for water supply, irrigation and power generation in Egypt. Since Egypt has a very hot and dry climate large amounts of water in reservoir is lost to the Nubian aquifer system and by evaporation. The consequences from constructing the dam are considerable.

The combustion engines in today?s vehicles are getting more and more advanced and there are increasing demands on that the engines should operate during optimal conditions. Examples of internal combustion engine parameters which may be carefully controlled are the rate between fuel and air, that this gas mixture is homogenous enough and that it is ignited at the correct moment. Moreover, the requirements of these parameters vary depending on, among other, engine speed and load. To meet these requirements in all occurring operation conditions, it is required that many subsystems work together.

Hungary?s share of renewable energy in 2010 was 7.9 %, and their renewable energy goal for 2020 is 14.65 %. Geothermal energy is one option that could help to achieve the goal, since Hungary has favorable bedrock, the temperature gradient is above average and thepermeability is high. Today Hungary is importing just over half of its primary energy supply. Because of political conflicts between nations Hungary wants to expand its own production of energy.

The purpose with this thesis is to investigate how a number of municipalities in Stockholm County proceed when they allocate land and establish land allocation agreements for exploitation, and to investigate how a number of municipalities define land allocations and land allocation agreements on the occasion of public land sales. The aim of this thesis is to describe the allocation methods a municipally uses when they offer land for sale and to give an insight regarding which correlation different land allocation agreements have in different municipalities.Methods used are: (1) a literature review where the underlying theory for land allocations and land allocation agreements have been studied; (2) a questionnaire have been done to complement the literature review and to provide a picture of how a number of different municipalities in Stockholm County use and apply land allocations; (3) an agreement audit have been done to see the extent to which different agreement terms exists.Responses from the questionnaire, together with the definitions form different municipality?s land allocation policies and the literature review, resulted in a definition of a land allocation and a land allocation agreement. The agreement audit shows that agreement terms regarding: price or price indication, location, cost-sharing and planning costs are the most common agreement terms within the municipalities we have investigated.The study suggests that there is some confusion regarding land allocation agreements and the meaning of these, that became apparent when agreements where gathered, despite a careful explanation that it was land allocation agreements we requested, we still got exploitation agreements and purchase agreements. Therefore, we consider it necessary with an official definition of a land allocation agreement well anchored in the Planning and Building Act together with the rules of development agreements or other legislation.That there is a lack of research within the subject becomes evident when reports, essays, and other literature generally refers so the same sources.Keywords: land allocation, land allocation agreement and public land sales.

ADHD (attention deficit hyperactivity disorder) is a phenomena that is much talked about in both schools and in communities. Today, there is a conflict surrounding the diagnosis ADHD. A part of the conflict takes part between the sociologist Eva Kärfve and Christopher Gillberg, professor in child- and teenage psychology. The roots of this conflict surrounds the much debated line of what is seen as normal and ?too? different, basically how many children that actually should have the diagnosis.

Introduction: More and more companies have realized that keeping and using the knowledge in their companies is getting more important to get or keep a competitive advantage. The companies? organizational culture and knowledge management are essential to create knowledge transfer. Also that the employees and the leaders of the company knows how knowledge- and information transfer arknkoe done best for them. That is why we chose our purpose to be:The aim is to understand the differences between managers and employees perception about knowledge- and information transfer in a manufacturing company.

Den här uppsatsen syftar till att undersöka de psykosociala påfrestningar som heltidsengagerade på studentnationer i Uppsala upplever i sitt arbete. Genom en kvalitativ datainsamling under sammanlagt åtta intervjuer med "heltidare" har deras arbetsmiljö kartlagts med fokus på arbetsmoment som de själva upplever som stressande eller påfrestande.Analysen har sedan skett med bakgrund av tre stressmodeller: krav-/kontroll, effort-/reward och allostatic load. Med stöd av tidigare forskning av Maslach & Leiter, Asplund och Thulin Skantze. Detta har givit en bred och heltäckande uppfattning av hur de psykosociala påfrestningarna påverkar respondenternas utifrån deras egna upplevelser av sin arbetsmiljö.Av de framkomna och analyserade resultaten har flera slutsatser uppkommit. Framför allt kan man konstatera att heltidare har ett i längden ohållbart tungt arbete sett till arbetstiderna.

THE CONSTANT IMPROVAL AND REFINEMENT OF THE MOBILE TECHNOLOGY HAVE MADE IT POSSIBLEto use video in settings where such use couldn't be motivated before, due to economicaland practical reasons. The purpose of the study was to identify and explore possiblechallenges in interorganizational use of video during emergency response work. Thiswas done by a case study of a system designed for the use of video in such situations.The study focused on operational challenges for the fire and rescue services and thehealthcare organisations, where the main challenges identified were intended to beanalysed and discussed in terms of design. The empirical results were gathered throughqualitative interviews with representatives from the fire and rescue services and thehealthcare organisations in Göteborg. This material made it clear that contextual aspectsof emergency response work lead to a couple of challenges connected to the use of videoin such situations.

Many of todays studies show that district heating is one of the betteralternatives as heating source because of its low environmental load.The energy source is often leftovers from other processes producing energy or waste, like garbage or chips.Electricity in combination with geothermal heating is another heating system that has increased sharply during the last years, and also this system decreases the discharges that have negative affectson the environment compared to several other heating methods.This report aims to, concentrated towards these two different heating systems, estimate the amounts of discharges they indirect cause and how the environment is affected.We have calculated the mean value for discharges of carbon dioxide, nitrogen oxide, sulphur oxide and dust generated from electrical power used in Sweden.Through interviews and research we have gained data for the same substances that district heating based on combustion of garbage and biofuel generates.We have also in cooperation with a housing company chosen a building we see representative for many of the new single-family houses built in Sweden today.Based on its shape and appearance we theoretically created three alternatives of the same house, each of them with climate screens different from each other.Together with the amounts of discharged environmental affecting substances, these houses were the base for our calculations and studies when investigating the different heating sources environmental effect.The results have thereafter been analyzed and discussed from different angles..

?Boverket? the Design Regulations in Sweden, also called BKR has for a long timebeen the mandatory standard that has guided and regulated construction design. Butat the end of 2010 BKR was replaced with Eurocode. This report deals with thecomparison of these two standards when it comes to wood construction. Duringwinter 2009/2010 there were many roof collapses due to excessive loads on theroofs across Sweden.

Sociala medier består av digitala plattformar där integration, kommunikation och delning är möjligt mellan användare. Under de senaste åren har nya former av sociala medier växt fram och blivit ett intressant område för forskning. Det har även blivit en ny kanal för marknadsförare att nå ut till sina kunder. Pinterest startades 2010 av Ben Stilbermann med syfte att användare kan dela bilder och skapa sina egna digitala anslagstavlor. Målet med denna studie är att analysera Varför svenskar använder Pinterest för att skapa en bredare förståelse av Pinterest som nytt socialt medium samt presentera dess funktioner, styrkor och svagheter.

AbstractNowadays, companies and organizations manage large amounts of data to be used as support in decision making. A good solution for data management is in the form of data warehouses. A data warehouse is used to gather information from multiple sources within a company and arrange the information in a way that makes it easy to retrieve and analyze. Designing a data warehouse is not a simple task. The study herein will focus on what a data warehouse is and how the ETL process is used for data storage in the data warehouse. ETL stands for Extract, Transform and Load and is the process that retrieves data, transforms it and finally loads it into the data warehouse.

Bakgrund: Vårdplatserna på svenska sjukhus har minskat drastiskt det senaste decenniet.  Detta har inneburit en högre beläggning på de kvarvarande och medfört längre väntetid på landets akutmottagningar. Platsbristen skapar, ibland dagliga, överbeläggningar och utlokaliseringar av patienter.Syfte: Att undersöka hur sjuksköterskor och läkare upplever att vårdplatssituationen påverkar deras arbete och vad detta får för konsekvenser för patienterna.Metod: Kvalitativ design med semistrukturerade intervjuer med tre läkare och nio sjuksköterskor från akutvårdsavdelning med inriktning infektion, mottagning med akutintag och akutmottagning. Analysarbetet genomfördes med Malteruds (2009) innehållsanalys. Resultat: Vårdplatssituationen kommer sig av en brist på vårdplatser inom främst medicindivisionen, samt en oförmåga att hålla de platser som finns öppna på grund av sjuksköterskebrist. Bristen på vårdplatser har inneburit en oförmåga för läkare och sjuksköterskor att utföra sitt arbete i enlighet med sin kompetens och beprövad erfarenhet.Slutsats: Svårigheterna med att finna platser till patienterna på deras hemavdelningar samt de ständiga omflyttningarna av patienter medför svårigheter för vårdpersonalen att ge god medicinsk vård och omvårdnad vilket medför stora risker för patientsäkerheten.
