In the last couple of years, an increase of electric bicycle users has been shown in Sweden, a trend that is assumed to continue. With an electric bicycle, the ability to reach a higher speed, and with greater acceleration, enhances compared to a traditional bike. For the surrounding road users, these factors makes it difficult to determine speed and risks which can lead to an increasing uncertain
This paper investigates the relationship between generalized trust and the size of government. Generalized trust has declined during the past 35 years globally. This matters for several reasons including that generalized trust correlates with growth, political participation and stability in society. To test this relationship, we use the World Value Survey and the European Social Survey together wi
Present essay investigates if the systemic riskiness of Eurozone and US systemically important banks decreased subsequently to the Global Financial Crisis of 2007/2008. For each of these institutions, time series of the analytical systemic risk measure MES are estimated based on public information. This is done using a bivariate time series model and involves estimation of time varying conditional
Marketing in the publishing industry is not a new phenomenon, but over the last ten years it has gotten a more central role within publishing. Technology has created new possibilities, but also changed our media habits. These changes have brought on a new kind of marketing. These days, social media marketing occupies a more central role in companies’ marketing strategy – and publishing houses are
Studien syftar till att undersöka hur olika faktorer påverkar svenska börsnoterade fastighetsbolag. Studien är baserad på en kvantitativ metod. Den insamlade empirin har bearbetats i MS Excel för att erhålla finansiella styrmått. Studien grundar sig i tidigare forskning för hur olika faktorer påverkar val av kapitalstruktur. Teorin är baserad på andra marknader men även på fastighetsmarknader i an
This project has investigated the performances of Capsule Networks in comparison to Convolutional Neural Networks (CNNs) on white blood cell image classification at CellaVision. The Capsule Network models that were investigated are EM Routing Capsule Networks (EMCNs) and Dynamic Routing Capsule Networks (DCNs). The models were compared with regards to convergence rate, speed, and accuracy performan
The unattended collection and delivery point (UCDP) is one of several solutions to address the delivery issues arisen by increasing online retail sales. There are four solutions of the UCDP concept: the traditional parcel locker, the automated box design, the automated pillar design and the cart design. Moreover, the physical dimensioning of a UCDP mainly needs to consider the number of orders, or
In empirical economics, the generalized method of moments (GMM) is one of the most widely used methods for estimating models with fixed effects, such as the dynamic panel model. For the dynamic panel model, the two most widely used GMM-based estimators are the so-called difference GMM and system GMM estimators. However, it is typically the case that such estimators are asymptotically biased of order
In recent memory the question of climate change has been at the forefront of a great deal of debates at the international level and with the Paris Agreement and the continuation of COP-meetings in the future, the preoccupation with climate change is sure to continue and to involve many different actors. The question of how a state such as Denmark, traditionally known as a state dedicated to fighti
In recent years, insufficient obstetric care has been a highly debated topic in Swedish media and politics. However, despite reports on e.g. the country’s high prevalence of birthing injuries, the recent closing of numerous maternity wards and a severe lack of midwives, the development of Sweden’s medical birth outcomes has been stable. Thus, based on the assumptions that (I) said quality measurem
Communities of Practice (CoPs) have been featured heavily in the literature of organisational learning and knowledge sharing in recent years. However, the concept denotes a paradigmshifting learning theory that goes beyond a mere management tool. In the present text, we review the CoP literature and argue that it lacks an elaborate explanation of CoPs’ organisation, resorting to saying they are ‘s
Following the UNHCR:s launch of the #IBelong Campaign to End Statelessness by 2024 in November 2014, a Global Action Plan to End Statelessness: 2014 – 2024 was adopted urging states to undertake ten actions to end statelessness, including to facilitate the naturalization of stateless migrants. While the facilitated naturalization of stateless persons would certainly reduce the occurrence of statel
Semantic Web technology has attracted much interest for its ability to integrate and deliver information from different sources, and increasingly, geodata are being published as triple data according to the graph structure laid out in the Resource Description Framework (RDF). Although the Semantic Web already contains a large volume of geotagged information, there is still a lack of suitable geome
The world as we know it today has evolved to be a very connected space, where not only ICT’s (information & communication technologies) have made it easy to interact with individuals around the globe at any time, but also developments in air travel allow to reach ever more distant destinations. Many go as far as describing the world as shrinking or small; it seems that at least it feels smalle
In recent decades, industrialized economies have significantly increased their R&D efforts while economic growth rates have been relatively stable. This goes against the conclusions of most previous economic models of endogenous growth. In this paper, an endogenous growth model has been created in which technology is treated as an income-compensated factor of production. The purpose is to crea
Denna uppsats undersöker hur den svenska barnrättsorganisationen Bris skapar förtroende och visar försiktighet i sina livechattar, som riktar sig direkt till barn och unga under 18 år. Syftet är att undersöka vilka språkliga strategier som kuratorer på Bris använder i sina svar till barnen för att skapa kontakt och närhet, men samtidigt visa respekt och hålla distans. I undersökningen utgår jag fr
The emerging market for meat substitutes has largely been filled with different types of soy products. Although soy usually has a lower environmental impact than meat, soy is not entirely unproblematic. Deforestation and global transportations are two negative effects of the increasing production of soybeans. One of these meat substitutes is tempeh: an Indonesian mold-fermented food usually made o
With a growing trend of electrification of vehicles there is a need for more flexible and advantageous charging options that reduce EV limitations. To overcome these limitations,dynamic charge through Electric Road Systems (ERS) is in development, and fast charging stations are being deployed all over the world. This thesis focuses on combining the use of both technologies, attempting to use an EL
Det har länge funnits ett fokus på att uppnå en säker och trivsam arbetsmiljö. Den fysiska arbetsmiljön har i över 100 år haft arbetslagstiftning och tillsyn för att skydda de anställda på svenska företag. Det var först år 2001 som regeringen gjorde en sammanslagning av Arbetarskyddsstyrelsen och Yrkesinspektionen som skapade Arbetsmiljöverket. Samma år beslutades det om en stor satsning på den ps
En diofantisk ekvation är en polynomekvation i två eller flera variabler, där polynomet har heltalskoefficienter och man söker heltalslösningar. Det enklaste (och kanske mest praktiskt användbara) fallet är det linjära, ax+by=c. I sådant fall är det enkelt att hitta lösningar (x,y), eller visa att inga lösningar existerar, med hjälp av Euklides algoritm eller kedjebråk. För diofantiska ekvationer This thesis deals with some special types of Diophantine equations. Two classic cases of Fermat's equation are shown to have no nontrivial integer solutions, using two different approaches. The rest of the thesis deals with some instances of y^2=x^3+k, commonly known as Mordell's equation. In most cases, no integer solutions exist.
