The population of the world is growing larger and getting older. This growth is causing an increased load on the current healthcare system, thus lowering the standard of healthcare. One group, specially affected by this, is the elderly and their homecare service and retirement homes. To unburden these services, safety alarms were created. However, these are in much need of design, ergonomic and te
Distance-based accessibility measures are often built using vector representations of origin and destination features, and Euclidean or network-based distances. There are few comparisons of how the choice of feature representations and distance types affects results. Existing comparisons often use Spearman’s rank correlation coefficients. This study seeks to understand the effect of using differen
Syftet med denna studie är att undersöka huruvida det föreligger något statistiskt samband mellan CSR och lönsamhet. 183 stycken företag listade på Nasdaq OMX Stockholm har undersökts mellan åren 2013 och 2014. Lönsamhet studeras ur det marknadsbaserade måttet, Tobins Q och CSR mäts ur både mänskliga rättigheter- och miljö genom Folksams Index över ansvarsfullt företagande. Vidare undersöker studi
This thesis explores the ontological assumptions made about the (sexed) nature of humans in four feminist theoretical accounts of sex and gendered power. The four works analysed are: Simone de Beauvoir’s The Second Sex, Gayle Rubin’s ”The Traffic in Women”, Judith Butler’s Gender Trouble and Elisabeth Grosz’ Time Travels. The ontological assumptions are analyzed with a critical realist approach an
Firms’ stock return volatility varies across countries, and the factors driving the volatility can contribute both positively and negatively to economic growth. We show that across 3,673 firms during the time interval 2001 to 2016, stocks of Swedish firms have on average lower volatility compared to stocks of foreign European firms of similar size, age, and market-to-book value. The lower volatili
How does Donald Trump’s passionate Twitter usage impact consumer confidence? This paper develops a new time series measure of Donald Trump’s Twitter based on a sentiment analysis using data from June 2016 to March 2018. Furthermore, we capture the economic sentiment based on computational text analysis using economic news articles from January 2000 to March 2018, assuming that Trump acts as an ext
This thesis empirically investigates the question if US firm’s capital structures are stable over longer periods of time and which firm characteristics drive optimal leverage. The analysis is based on a Compustat panel data sample consisting of 2,900 US firms between 1985 and 2016. After analyzing the stability of firm’s capital structure via a “narrow band” and a “relative bucket approach” an err
The purpose of this study is to examine how social workers in Sweden engage in policy practice to influence policies, guidelines and methods that contradict their professional values. Based on Hirschman’s theory of exit, voice and loyalty, we analyse social workers’ strategies for change. The study problematizes some challenges social workers face in order raise their voices, but focuses on possib
As globalization and technological innovations continue to support the rise of multinational corporations, it has become increasingly pressing for business to cater to a worldwide audience. Particularly, websites from these companies must be both navigable and easily comprehendible to individuals across cultures to cater to global audiences. Interestingly, however, few studies have explored how in
There has been previous research on the subject of preferred stock and its classification as debt or equity. This thesis adds to the discussion by incorporating a comprehensive measure for financial standing. In this thesis, preferred stock returns of 74 companies are regressed on the returns of bond and common equity and a measure of default probability. The result of the study is that the majori
In September of 2017, the Swedish government introduced a proposal for a new Consultation Act that would require the government and other state agencies to consult with the indigenous Sami people on issues of importance to them. The aim of the proposed law is to strengthen and promote the influence of the Sami people over their own affairs. This thesis analyses whether the proposal is in line with
With a starting point in the notion that witnesses are a neglected category of individuals of the criminal justice system, this study critically examines policy discourses within the jurisdictive process regarding witnesses’ legal position. By conducting a discourse analysis with a critical approach, the study analyzes a corpus of textual data comprised by a subset of policy documents on the area
Toeplitz operators acting on Hilbert spaces of analytic functions are among the most well studied examples of concrete operators. In our work we are interested in a cut-off property of such operators; namely, if the operator is small enough, does it have to be zero? Or more in general, must its symbol be of a particular form? There have been several such results, and in the Hardy space the answer
In the suburbs of Milan, Italy, where the tarmac merges with the fields, the district of Chiaravalle and its Cistercian abbey withstand the passing of time. This is the setting, where the cultural association Terzo Paesaggio operates, aiming at the reactivation of the relationship between the local human community and its environment through an interdisciplinary approach based on landscape archite
Vårt långtidsminne har en avgörande roll i våra liv. Det ligger till grund för vår uppfattning av det som har hänt, det som händer just nu och det som kommer hända i framtiden. Två viktiga funktioner av långtidsminnet är förmågan att urskilja liknande intryck från varandra och från tidigare minnen samt förmågan att framgångsrikt associera fram det som har hänt med hjälp av mindre beståndsdelar. De
The purpose of having a high-quality education system is not only to increase the human capital level of the younger population, but also a mechanism to minimize the differences between children’s chances to succeed in life. Children who come from poor backgrounds and have low educated parents will be given a possibility to succeed through a high-quality education system. This thesis will investig
Det blir allt vanligare att verksamheter lanserar chatbottar som en del av sin kundsupport. Möjligheten att erbjuda sina kunder snabb respons dygnet runt är lockande. Men alla användare verkar inte lika positiva, chatbottarna kan ge konstiga svar eller presentera dåliga lösningar. Med hjälp av en kvantitativ undersökning utvärderas användares upplevda acceptans gentemot support bestående av chat
The argument put forward in this paper is that stocks listed on the Stockholm Stock Exchange, from 1993 to 2016, exhibits return continuation over an intermediate-horizon. The best performing strategy, which selects stocks based on the previous six months’ returns and holds the portfolio for three subsequent months, yields an average monthly return of 2.33%. Moreover, results are robust after risk
