How to future proof a Business Model : Capture and capitalize value in the field of Urban Mining
Context: During the 21st century several alarming reports have been published that deals with the depletion and pollutant of the earth by human interference. The earth is an ending resource and so are the mountains and bedrocks which are continuously mined in order to harvest its minerals. The idea behind Urban Mining is to (re)invent processes enabling further purpose for materials both from old deposits and new products providing secondary raw materials and energy. This thesis aims to investigate the challenges and opportunities of how firms and organizations can and will be able to strike a better balance between product-/service systems, economic growth and environmental stewardship in the context of Urban Mining as an approach. With the innovation of processes, technology, business- planning and creation in focus.Objective: How to future proof a business model for Urban Mining by the usage of business model design.Method: This thesis will be conducted using a case study approach, meaning that it will incorporate qualitative, exploratory and descriptive characteristics - aiming towards enabling both applied and fundamental research.Results: The result evaluates the business model element differences between traditional C&D industry and Urban Mining industry.
Ett förlorat kulturarv? : Digitala personarkiv ? problem, lösningar och framtid
This thesis has focused on digital born personal archives; how they are different from analog paper archives and possible ways to overbridge these differences. It is also studied how archivists and librarians are dealing with digital archives, what they think about new proactive solutions when collecting private papers and collections and positive and negative effects with this way to work. The thesis is delimitated to only private collections and digital created material. It do not concern digitized material or electronic documents in government or business organizations.The challenges in digital curation and administration are discussed in aspect of the Records Continuum Model.

Migration of a very large database with Swedish demographic data, using Microsoft SQL Server
SMC is in the process of developing a micro simulation model. The existing micro simulation model developed at Cornell University for US data, CorSim, is one of the fundamental parts for the new micro simulation at SMC. To develop the Swedish model, Swedish data on all individuals in Sweden during 11 years are also available. These data are organized in a database. This paper describes the process of rebuilding the database to a more useful structure.

This master thesis is a study of the Swedish hydropower capacity to balance wind power. The Swedish government has decided that it should be possible to produce 30 TWh from wind power in the year 2020. The Swedish municipalities have to have plans for wind power plants with total yearly generation of 30 TWh. Wind power is an variable energy source that needs to be balanced by other energy sources. In Sweden the Swedish hydropower can be used for balancing a large scale introduction of wind power.
The implicit heteronormativity
Our society is based on a heterosexual norm. This may lead to the fact that LGBT-persons have a poorer health status than the heterosexual population. The nurse education lacks information and courses that highlights sexual identity. This is defective since healthcare staff needs knowledge on the subject to be able to treat patients in a professional and respectful manner. The purpose of this study was to illustrate how heteronormativity influences the treatment of patients within a healthcare context.
Utvärdering av lokal styrelse i Veberöd - En deliberativ demokratisk utvärdering
This thesis evaluates the user board of the elememtary school in Veberöd, Sweden. In this process an evaluation model is developed. The model itself gets evaluated in a meta-evaluation to improve the model for future use.The starting point of the evaluation is the deliberative democracy theory. Although Sweden is a representative democracy an official desire exists to have a democracy with deliberative qualities. The evaluation model is constructed to fit this context and is therefore, not only, set out from classical goal-based evaluation but also from deliberative democratic evaluation.
?Vård i annans hem? - användning av arbetsmaterialet i Huddinge kommuns hemtjänst/boendestöd och personlig assistans
AbstractThe importance of good construction planning affects the final costs of the production and the timing of the project. Planning for building projects has been studied with the aim of identifying how three week planning appears in the construction industry today.A case study has been conducted in Navisworks Simulate to assess whether the software is suitable to connect the task schedule with the BIM model to create a 4D model. 4D models are used for performing 4D construction simulation to visualize the project. In order to use the benefits of the model, investment in equipment and software is required. This means higher costs for the companies.
Reformation of the credit rating industry - Is there a need?
The credit rating industry is a complex and fascinating industry. Its history stretches back more than 150 years and has gradually increased in importance. During its history the dynamics of the industry have changed. The extended-principal-agent model was developed by synthesizing different principal-agent-relationships into one model. This model provides a holistic understanding of the credit rating industry and illustrates the interdependence between the different relationships.
Förslag till modell av kemikaliespridning i mark anpassad för användning vid räddningsinsats - Kemspill Mark 4.0
After emergencies involving chemical spills it is of great importance that correct measures are taken with short notice, both for the security of people and in order to minimize future environmental consequences. The RIB-unit at the Swedish Rescue Services Agency initiated this study, the aim of which is to propose changes to the existing chemical transport calculation tool: Chemical Spill 3.4, included in RIB - Integrated Decision Support for Civil Protection, so that it can be used for decision support as well as in preventive work. A rough estimation of chemical transport in the subsurface is considered being of great importance when making decisions during emergency response operations.The proposition presented in this report is a non site specific chemical transport model which is designed to give a rough estimation of NAPL flow in homogenous isotropic soil shortly after an instantaneous release. The model can be used at two levels; both in situations without access to information on subsurface properties, and with more accuracy in situations with knowledge of the included parameters. For that reason the user can choose among predefined alternatives or assign the parameters a numeric value to increase the quality of the model output.
Estimering av kreditbetyg - Syntetisk rating med Ordered Probit Model
Calculations of net present value are based on a discount rate, which requires knowledge about the company?s cost of debt. A common way to do this is by observing the company?s credit rating, when no credit rating is given it?s possible to use a synthetic rating model based on quantitative data to estimate a credit rating. Thus, the aim of this study is to increase the understanding of which quantitative data, in terms of key figures, that can be used to explain the given credit ratings for companies from the Nordic countries.In developing the model, key figures found significant in previous studies are being tested for whether or not they are applicable for companies from the Nordic countries.

ISIT-modellen - Vägledning för att realisera en verksamhets informationssäkerhetsmål
The ISO standard ISO/IEC 17799/SS-627799-2 is a guidance for organizations to
realize their information security goals. In spite of this standard, studies
show flaws regarding information security in organizations. In particular flaws
regarding overall view, knowledge and clear roles and responsibilities have
been observed.
The ISIT (Information Security Integrated Three level) model and its
guidelines, developed in this thesis, help organizations to identify the
required processes and procedures as well as the logical process flow. The
thesis is based on theoretical studies and a case study within a multinational
company.
Känslighets- och osäkerhetsanalys av parametrar och indata i dagvatten- och recipientmodellen StormTac
Three methods of sensitivity and unceartainty analysis have been applied to the operative stormwater- and recipient model StormTac. The study area is the watershed of lake Flaten in the municipality Salem. StormTac?s submodels for stormwater, pollutant transport and the recipient are cosidired. In the sensitivity assessment, the model parametres and inputs were varied one at a time by a constant percentage according to the ?one at a time? (OAAT) method and the response of the outputs were calculated.
Är du kvar på ditt gamla dammiga bibliotek? Bilden av bibliotekarien i svensk skönlitteratur 1982-2002
The aim of this Masters thesis is to examine how the images of librarians are conceived and held by the public. It has often been claimed that librarians are subject to widely spread negative stereotyping. My purpose is to study the nature and origin of these stereotypes. Since popular media is one source of these stereotypes and images I have chosen to look into how librarians are characterized in 20 Swedish novels written between 1982-2002. The questions this thesis aims to answer are: What images of librarians occur in the novels? How are the tasks of the librarians respectively described in the novels? How are female and male librarians respectively described? The analysis of the novels is then compared with interviews with three professional librarians about their view of their professional role and their perceptions of its status and image.
