Imputation of data is the process of filling in missing values in an incomplete data set. Missing data is a common problem in many fields, not least in clinical research. This report aims to evaluate different methods for imputing missing data in health records of dialysis patients. The imputed data will, in a related project, be used to predict hospitalizations of dialysis patients. The hope is t
Development towards a connected world where anything can talk to anything is ongoing. Calvin is a research project at Ericsson that simplifies the development of peer-to-peer applications for the Internet of Things. Calvin is created in order to let the developer of an application for the Internet of Things focus on the implementation instead of having to worry about underlying protocols, hardware
The United States is the only OECD country to not provide universal health coverage to its citizens. While majority of the population is able to obtain insurance through employer-sponsored plans, many low-income adults fall victim to the ‘coverage gap’ – earning too much to qualify for state-funded social programs, in jobs that fail to provide a viable alternative. The central aim of the Affordabl
Previous studies have proven that stress factors linked to academic achievement is the main cause of stress in the life of a student. However other reports have indicated that other factors concerning casual sexual behaviors and attitudes may have a negative effect on the well-being of students. Questionnaires were handed out to 227 students at Lund University, 83 men and 143 women, to investigate
Bakgrund: Vi upplever att de tongivande forskarna inom den nordiska tjänsteforskningen är alltför konceptuella i sina slutsatser, då de sällan tar hänsyn till vad som djupgående krävs i kontexten inom olika verksamhetsområden. Då framgångsrika tjänsteverksamheter inte enbart är individanpassade, utan även situationsanpassade, finner vi att de förutsättningar som specifikt människonära tjänsteverks
This report presents a mathematical kinetic model describing the recovery of metal ions as metal sulfides, using sulfate reducing bacteria (SRB). Metal recovery from industrial waste is a potential beneficial and unused source of metals. The developed kinetic model is implemented and simulated in the computer programs MATLAB R2014b and Aspen Plus V8.8. The MATLAB simulation is performed on the bio
The building sector is the greatest single contributor to anthropogenic greenhouse gas emissions. A change in the patterns of building practices has the potential to contribute to mitigate the sector’s CO 2 emissions. Contemporary governance mechanisms see Non-Governmental actors take a considerable proportion of the action with market mechanisms. Building Councils as multi-stakeholder, non-state
This study analyses the effect of an exogenous increase in Chinese imports on political views in 9 EU countries over the period 2000-2009 by exploiting initial regional variation in industry specialization of labour markets. The labour market data is combined with data on industry specific Chinese imports to create a measurement of region-specific exposure to import penetration. To avoid endogenei
Inn ultra-relativistic heavy-ion collisions, QCD matter undergoes a phase transition to a strongly interacting Quark Gluon Plasma (QGP) where quarks and gluons are deconfined. The expansion of this plasma is well described by ideal hydrodynamics, suggesting that it behaves like a perfect, reversible, liquid. The particles emerging from the expansion are then highly correlated, showing collective b
Consumerism contributes to sustainability problems of social fragmentation and environmental degradation. In response to this the sharing economy is a relatively new and rapidly growing phenomenon. While the for-profit sharing economy has received considerable academic attention and critique, there is a lack of research that explores the alternative: the non-profit sharing economy. This paper addr
Det kommersiella värdet av personuppgifter och behandling av dessa är av stort värde för aktörer i den digitala ekonomin. Den ökade insamlingen och behandlingen av personuppgifter utgör risker och utmaningar, inte bara för att skydda EU: s medborgares integritet och personuppgifter, men också för den fria konkurrensen på den inre marknaden. Nya aktörer kan behöva ha tillgång till personuppgifter fThe commercial value of personal data and the processing of these is of great value for players in the digital economy. The increased collection and processing of personal data poses risks and challenges not only to the protection of EU citizens’ privacy and personal data, but also to the competitive environment on the internal market. New entrants may need access to personal data in order to comp
In this study, we analyze the hedging activities for risk management purposes of 31 shipping companies headquartered in Europe and North America and its impact on ROIC, in the period between 2009 and 2014. We also study how ROIC interacts with hedging and investments undertaken by the firms in our sample. If some of the assumptions of the Modigliani & Miller (1958) framework are relaxed, hedgi
This master thesis investigates how personal narrative and emotion might be understood as a feminist strategy in the work True Stories, an autobiographical project by contemporary French artist Sophie Calle. This is done through the application of Judith Butler's theory on heteronormativity, performativity and subversive acts, as well as Sara Ahmed's thought on emotion. The result shows ho
Denna uppsats undersöker översättning och lokalisering av dataspel för den svenska marknaden. Studien utförs mot bakgrund av att engelskan har en mycket stark ställning i Sverige och inom dataspelsgenren. Uppsatsen bygger på en korpus som består av 104 dataspel som har sålts i Sverige åren 2009-2015, vilka har hämtats från försäljningsstatistik som finns tillgänglig från organisationen Dataspelsbr
The microstructure in cortical bone greatly affect the toughness of the bone and the crack propagation during fracture. The two main structural features, Haversian canals and osteons, have been previously studied in order to increase the knowledge of the biomechanics of bone. In studies where X-ray microtomography has been the imaging method of choice, the microstructure has been analysed based on
Within the mobile age, it has become critical to protect users’ privacy from privacy-invasive apps that access and collect personal information unnecessary for the apps function and, companies who share and sell user data. The advancements in mobile technology have led to the creation of voice-activated intelligent personal assistants (IPAs) which have been linked to privacy issues among users due
Sammanfattning Denna uppsats syftar till att undersöka hur individer skapar sin sociala identitet genom grön konsumtion med utgångspunkt i Fairtrade-caféet Barista. Vidare ämnar denna uppsats undersöka anledningarna till varför individer konsumerar grönt ur ett konsumtionsteoretiskt perspektiv och detta har således lett oss till följande frågeställningar: Hur skapar konsumenter sina gröna ident
Since Actor-Network Theory emerged in the mid-1980s, the approach has transcended disciplinary boundaries and has similarly gained prominence within geography. Moreover, also the main proponents of the approach have endeavoured in linking Actor-Network Theory to geographical lines of inquiry and sought to develop a spatial vocabulary that matches its distinctive thought system. However, few attemp
In an efficient market, assets reflect all available information. Hence, investors cannot earn abnormal returns by conducting fundamental analysis since all financial data is impounded in the asset. The only way for an investor to earn higher returns is by incurring increased risk. However, a growing body of evidence appears to contradict market efficiency and common notion of risk compensation. P
Colombia is a country characterized by an intense internal armed conflict, which has its foundation in political instability followed by discontent among the population of the country. With the rise of drug lords, rebel groups, paramilitaries and army the conflict has continuously intensified towards the government, which has left countless of civilians displaced and vulnerable. The political corr
