Nätverk på nätet: Innovativt värdeskapande genom samarbete

A constantly increasing number of magazines are using the Internet as a business channel. One of these is Allt om Mat (All about Food). Together with expressen.se, Allt om Mat developed a food website, alltommat.se, which was introduced at the beginning of 2008. In this essay we investigate how alltommat.se developed its service concept. Further, we look at how this development has influenced and been influenced by relations among the three actors and the users.

Dolt i det öppna

Communication is a part of everyday life. The more sensitive information we handle, the more interesting the question around security of your information becomes. There are two ways of handling security around the information you want to communicate, either you control the means by which you are communicating. Or you control the way you communicate, making you able to use existing communication channels. Existing methods within cryptography enables two parties to communicate information securely.

En studie av zero knowledge-identifikationsprotokoll för smarta kort

Zero knowledge protocols is a lesser known type of protocol that can be used for identification. These protocols are especially designed not to reveal any information during an identification process that can be misused later on, neither by the one who should be convinced of the identity of the user, nor by anyone else that is eavesdropping. Many of these protocols are also especially designed for implementation in smart cards. The more common type of card with a magnetic stripe has during the last few years become more susceptible to attacks since they are easily copied. Smart cards combined with a secure identification protocol has been predicted to be the solution to this problem.

Spårtaxisystem i Uppsala

An increased awareness about the global warming has created a demand for more information on how the climate is affected by different activities.This master thesis was initiated by Tricorona, a Swedish company that offers its customers analysis and calculation of their climate impact. Tricorona also supplies climate neutralisation with CERs, in accordance with the Kyoto protocol and controlled by the UN. This work demands updated emission factors for greenhouse gases. An emission factor gives information about the greenhouse gasintensity of a service or a product [kg CO2-eq./ functional unit].The purpose of this thesis is to examine how electricity, district heating, hotels, taxis, food and materials affect the climate and how emission factors for these areas can be calculated.This was done by reviewing and comparing different studies and by interviewing experts. The information was evaluated and recommendations on calculations and emission factors were made.The consumption of energy is the main source of greenhouse gas emissions for district heating, electricity, hotels, taxis and materials.

Samverkan 4 U : En studie om samverkan med organisationen Here 4 U

The present study sought to examine the collaborative role of the student organization Here 4 U and the impact of this collaboration on the organization and its partners. As a point of departure a questionnaire was distributed to supervisors, principals and other cooperation partners of Here 4 U, the most prominent quantitative results of which were related to previous research, new institutional theory and empowerment theory. It turned out that partners interacting with Here 4 U felt that the collaboration was necessary and wanted to continue with it. The respondents to the questionnaire were asked to define the concept of collaboration. Factors emphasized by respondents included feeling of community, security, and common goals.

Ledningens skådespel: Hur tolkar aktieanalytiker bolagsledningars framföranden?

There has been an increase in the importance and amount of information concerning publicly traded stocks in recent years. When analyzing and valuing stocks finding new ways of collecting information has therefore increased in importance. This thesis aims to explore how meetings with management can impact the stock valuation done by the security analysts. Furthermore the case study examines what kind of information analysts can receive by interpreting management at these meetings. This case study of ten Swedish security analysts show that the analyst?s stock valuation is directly or indirectly affected by the meetings.

Järnberikning av mjöl : exemplifierat med Egypten och Iran

The purpose of this study is to give an overview about iron fortification from the view of technique and health. Example of a technical aspect is different iron compounds which are used for fortification like ferrous sulfate, ferrous fumarate and elemental iron. In the aspect of health the big question is if iron fortification can improve the health in reducing the prevalence of anemia. The study focuses on flour fortification with iron in Egypt and Iran and involves a literature study with scientific articles. Also information from WHO (World Health Organization), FAO (Food and Agriculture Organization) and FFI (Flour Fortification Initiative) are used.Fortification means an intentionally increasing of the content of micronutrient in foods with the aim to improve the food quality and deliver a nutritional benefit to the consumer.

Om solidaritet och ansvarstagande i världen : en diskursanalytisk studie kring internationaliseringen av svensk försvars- och säkerhetspolitik

The world is increasingly coalescing, ecologically, economically and culturally. Many problems can no longer be solved within the own state borders and the limitation of the territorial state is obvious. Jürgen Habermas means that a world domestic politic without a world government is what this progress need. Therefore it is important that national interests become less central and the solidarity between people is given priority in international relations. The focus of this thesis is therefore a critical discourse analysis of the current position of the internationalisation of Swedish security and defence policy.

En app för smartare måltidsplanering

This thesis is based on design theory about how to build an application for the mobile platform, a scientific analysis and an application for grocery shopping and meal planning. The thesis also contains a valuation of the research and of the application. The valuation of the application was done by a usability test and an analysis of the results of the test.The application of the thesis has an easy navigation system, which is time saving and simple to use. Finding recipes with the associated ingredients is a quick fix. The search function can be used for searching freely after recipes as well as for separate ingredients. That makes it possible for the user to create own recipes from available ingredients.

The prototype was based on the activity theory of Engeström. An ongoing project started in spring 2003. The purpose of the project is further development of IMIS with special focus in the diabetes healthcare. Participants in the project are scientists and students at BTH, ALMI Företagspartner, Blekinge FoU-enhet, Barndiabetesförbundet Blekinge, Blekinge Diabetesförening, Vårdcentralen Ronneby and Vårdcentralen Sölvesborg.

Klimatförändringar och dess effekter på ogräsfloran i Sverige :

Land management for food production is a fundamental human activity and one of the greatest challenges of the 21st century will be to increase the global food to accommodate a world growing to 10 billion or more people, while undergoing climate change. The increasing temperature and the current and projected increase in concentrations of CO2 lead to concern over possible impacts on agricultural pests. This assay is summarizing the knowledge of weeds in a changing climate in Sweden. Global warming and other climatic changes will affect the growth, phenology, and geographical distribution of weeds. The climate change will also affect the weed composition indirect by causing changes in the agriculture.

Säkerhetsmedvetenhet vid daglig IT-interaktion hos hemanvändare

Dagligen interagerar människor med IT-system och internetanvändning har blivit en viktig del i många människors liv. Med fler användare än någonsin hanteras ofantliga mängder information och samhället ställer allt högre krav på IT-säkerhet. När det gäller att skydda sin integritet, tillgänglighet och sekretess vid internetanvändning fokuseras det ofta på tekniska åtgärder, såsom brandvägg och antivirusprogram. De tekniska åtgärderna skyddar användaren till viss del, men det räcker inte för att förhindra ett bekvämt och naivt mänskligt beteende. När säkerheten brister beror det oftast på den mänskliga faktorn.

Barn som söker negativ uppmärksamhet : En intervjustudie om ett av förskollärarens pedagogiska dilemman

The purpose of this qualitative interview study was to examine which approach experienced pre-school teachers have on children that seek negative attention. The study contains five informants in a city in the middle of Sweden and they all have at least 10 years of experience after their diploma from a pre-school teachers? program. The questions I aimed to answer were the following: How did the pre-school teachers define the expression ?negative attention?? What approach did they have on children that seek negative attention? What effects do the childrens? seeking of negative attention generate on their self-esteem and sense of security? How possible do the pre-school teachers feel it is to achieve the goals of the pre-schools? curricula that every child should get their needs respected and met, when they work with children that seek negative attention? The results showed that the teachers think of them as resources in the group and that they need to think of the environment around these children both at home and at the pre-school to better meet their needs.
