Crowdsourcing och den kollaborativa ekonomin är modeller för öppen innovation som blir allt mer centrala i ett samhälle som står inför morgondagens utmaningar. För att ta itu med globala problem krävs det ett globalt samarbete och ett gemensamt ansvar, där delningsekonomin kan bli avgörande. I denna kvantitativa undersökning svarar vi på frågeställningen om hur upptagandet av och beslutsfattandet kring kollaborativa tjänsteinnovationer kan se ut när vi låter 50 studenter ta del av en kollaborativ tjänsteinnovation. Vi undersöker några befintliga kollaborativa tjänster, redogör för relevanta begrepp och visar på hur Diffusion of innovations kan användas för att förstå något så komplext som hur innovationer kan upptas och spridas i sociala system. Vidare visar vi hur ramverk för konceptualisering av crowdsourcing kan användas för att förstå hur miljöaspekten och viljan att samarbeta kan driva en stor grupp människor till att dela på kompetens, resurser och kunskap.

I den här rapporten utvärderas ett antal olika collaborative filtering algoritmer för att ta reda på vilken av dess som lämpar sig bäst för att implementera åt PlanEatSmile i en PHP/MySQL-miljö. Målet är att hitta en algoritm som klarar av att skapa rekommendationer i realtid och med hög precision. Därtill är det viktigt att algoritmen ska kunna skapa rekommendationer åt nya användare (cold-start-problemet) samt att algoritmen ska skala väl när sajten växer.De algoritmer som undersöks är user-based collaborative filtering, item-based collaborative filtering och tendencies collaborative filtering. Samtliga algoritmer undersöks i två versioner. En version som utgår ifrån receptbetyget och en version som omvandlar receptbetygen till  ingrediensbetyg.Algoritmerna testas på data insamlat genom en enkät för att avgöra deras precision.

Fler och fler spel öppnas upp för användargenererat innehåll, vilket ofta resulterar i större mängder material än vad en ensam spelare kan utnyttja. Den unika spelare vill ta del av det som passar just dennes smak.Studien genomfördes med designforskning som metodval och med hjälp av denna metod skapades en artefakt. Med hjälp av den utvecklade artefakten, ett plattformspel som är både enkelt att förstå och spela, kunde en datamängd samlas in ifrån olika spelare. Data byggdes upp av att användarna efter varje slutförd nivå, explicit fick lämna sitt betyg på nivån i en skala mellan 1 och 5.Genom att introducera collaborative filtering och där låta användarens tidigare betyg jämföras med övriga användare kan en predicering av kommande betyg ges. Vid jämförelser av olika collaborative filtering-algoritmer kunde den mest lämpliga upptäckas och senare även användas.Resultaten visar att mer precisa uppskattningar av kommande betyg kan göras av collaborative filteringen än genom att använda nivåns medelbetyg och resultaten leder därför till slutsatsen att collaborative filtering kan ge skräddarsydda spelupplevelser för en unik användare och således förhöja dennes spelupplevelse..

This thesis paper presents experiences and views on collaborative writing from interviews with university students. Analysis of these interviews, focusing on problems with coordination and technological tools,  shows that problems to some extent can be avoided with knowledge of the tools used and knowledge of coordination..

The topic of this essay is whether the private owned ammunition factory Norma Projectile AB was a part of a war economy system from 1938 to 1943. This is done by analyzing specific documents from the company´s archives that expose the connection with Swedish authorities. The selection and analysis of these documents are based on four main criteria?s of the concept war economy. These criteria?s are based on Ivan T.

This study has been carried out as a part of the EC funded project, SMARTDOC IST-2000-28137, with the objective of developing application components that provide highly interactive visualization and collaboration functionalities. The low-level components from the graphics library AVS OpenViz 2.0 are used as the development basis. The application components can be inserted into electronic documents that allow embedded controls such as web documents or Microsoft Word or PowerPoint documents. Instead of displaying results as static images, a SMARTDOC component provides the ability to visualize data and interact with it inside the document. Although the principal goal of the SMARTDOC project is to create components in a number of different application domains this study concentrates on developing a medical imaging application component in collaboration with the project partners AETmed and professor Alan Jackson at the University of Manchester.

Introduction: Mental illness is a public health issue which 20-40 per cent of the inhabitantsin Sweden suffer from. Many factors can lead to mental illness and because of that it isimportant that different organisations and professions collaborate in prevention and healthpromotion work. To develop the collaborative process by noticing difficulties and successes,documenting, follow-up and evaluation is of great importance. Aim: The aim of this literaturereview is to investigate which methods are used for evaluation of health promoting anddisease preventive collaborative projects, which focuses on mental health directly orindirectly, and find out what results these projects has revealed. Method: Literature reviewwith descriptive design.

Collaborative music making on the Internet is not a new phenomenon, but no applications have yet caught on with the vast number of laptop and bedroom studio musicians active today. This is strange considering the inherent social and interactive nature of music, especially amongst trends like Web 2.0 where collaboration and user-generated data is key. In this paper I study the problems these applications face, and why they do not have a greater appeal to musicians. With the results I develop and evaluate my own framework, known as Crescendo Online: a multi-user sequencing and modular synthesis environment, intended to pave the way for a new type of online music creation platform..

In today?s individualistic society, I experience a need to bring forward the importance of collaboration. From a sociocultural perspective, I have chosen to highlight the positive and negative aspects of collaborative learning, with the intention of illustrating the effects for the individual learning and development. I have therefore made an interview with an educationalist, who?s been a teacher all her grown up life, with the intent of illustrating her thoughts on collaborative learning.

The token economy program, which is a method for behaviour modification, has been used worldwide for different groups within different settings in order to vhange behaviour.Research has found the token economy program to be effective. However, research is limited to quantitative and experimental studies, and Swedish research in this field is brief. Nevertheless, the program is used in several institutions n Sweden. A qualitative study in Swedish settings could therefore be useful. The purpose of this paper is to examine the experiences of a token economy program using qualitative interviews.

Background: Running economy is one of the key factors to achieve top performance in endurance events. Little evidence exists for improving running economy using high-intensity interval training while running. Objectives: The purpose of this study was to examine how HIIT affects running economy and VO2max. Method: 14 well-trained athletes (age 35 ± 8,9 years, height 175 ± 11,7 cm and weight 69 ± 12,2 kg) were divided into two separate groups (HIIT and Control). HIIT group performed 3 HIIT exercises every week for 4 weeks and Control group continued with their separate training programs consisting of mostly traditional endurance training. Results: Running economy showed no improvement in HIIT (pre 38,62 and post 38,62 ml/kg/min, p=1.00) but Control improved (pre 45,41 and post 43,37 ml/kg/min, p=0,03). VO2max decreased in HIIT (mean 61,32 to 60,84 ml/kg/min) and in Control (mean 61,99 to 58,47 ml/kg/min)..

Economy and environment has for a long time been studied separately and seen as incompatible. With a growing society and increasing pressure on environmental issues the need of a new economy with the environment included is necessary. This study examine if European Union´s picture of the waste hierarchy match the reality. Since the purpose with the waste hierarchy is to benefit environmental and economy. A survey was made over Käppalaförbundets waste from 2013, to see where the waste falls in the waste hierarchy.
