Denna uppsats behandlar förekomsten av rumslig autokorrelation i residualer till paneldatamodeller med tvåvägsfel. Tre modelltyper undersöks: den linjära paneldatamodellen, en dynamisk paneldatamodell och en spatial paneldatamodell. Ett känt resultat för den linjära modellen, att minsta kvadrat-skattaren tillämpad på oberoende observationer resulterar i en rumslig korrelation i residualserien varsThis thesis examines the spatial autocorrelation in residuals of two-way error panel data models. Three types of models are examined: the standard linear panel data model, the dynamic panel data model, and the spatial lag panel data model. A known theoretical result for the linear model, that the within estimator applied to independent observations results in a spatial correlation in the residuals

The aim of this study was to look into the relationship between language and identity in the swedish novel "Tan". The protagonist is a man who suffers from severe speech, reading and writing disabilities and is based on the true story of the neurologist Broca´s most well known patient.

Data editing is one of the most important processes in order to achieve high quality statistics and is at the same time the most costly processing in statistical production. Therefore, many attempts have been made, over time and worldwide, to find effective ways to improve methods and at the same time limit costs of editing. This thesis dives into the concept of data editing and selective editin

This study investigated the relationship between perception of transformational leadership and burnout experience and determined the mediation effect of organizational factors on this specific relationship within a Swedish construction company. Further, differences between blue- and white-collar workers in the perception of transformational leadership and burnout experiences were examined. It was

In this paper, we look to develop understanding of the nature and potential impact of financial stress and fiscal shocks in the Chinese economy, examining how such stress spreads through the economy and how monetary policy can exaggerate or mitigate the resultant effects. In order to do so, we construct a TVAR model on Chinese quarterly data. To achieve that we develop a financial stress index com

The purpose of this study was to investigate attitudes towards gender and predicates denoting intelligence among Swedish and U.S. citizens between 20 and 35 years (N = 72). Research suggests that stereotypes on gender and cognitive ability begin to affect children around six years of age. These stereotypes may affect children over time and influence what career paths they will one day pursue. Furt

This thesis investigates whether the share of female legislative representation on a national level has an impact on public expenditure on social issues such as health care, education and elderly care. Using panel data primarily from the Comparative Welfare States dataset I perform a within-country analysis over time using both OLS and IV estimations. I use two instruments, laws on gender quota an

The purpose of the report is to study the yellow cycle route in the city of Lund and investigate the inadequacies that could be found on today's route. The yellow cycle route goes from Dalby in the south to Gunnesbo in the north. The method used to answer the questions of this report is literature study and a technical inventory. The analysis of the studied route is based on Lund’s cycle strat

Value at Risk (VaR) is a popular measurement for valuing the risk exposure. Correct estimates of VaR are essential in order to properly be able to monitor the risk. This thesis examines a copula approach for estimating VaR for portfolios of commodities. The predictions are made from a semi- parametric model with Monte Carlo methods. The underlying model is constructed by choosing the best fit from

Problemområde: Turism är en stadigt växande bransch och många reser för att koppla bort från vardagen. Samtidigt ökar medveten om hållbarhetsfrågor vilket genererat ett intresse för verksamheters ansvarstagande i frågan. I studien undersöks hotellens vattenbesparande strategier eftersom det fanns exempel då de påverkats av gästens upplevelse. Det identifierade problemområdet är således hotellens b

För att motverka klimatförändringarna har Sverige satt som mål att växthusgasutsläppen från inrikes transporter ska minska med minst 70 % senast år 2030 i förhållande till år 2010 (utom inrikes luftfart). För att uppnå detta krävs en satsning på förnybar energi. Skånetrafiken har målsättningen att bli fossilbränslefri senast år 2020, dessutom vill de använda biodrivmedel som genererar så lite växt

In our thesis project called (S)ink we combine an experimental computational approach to flooding and sea level rise with a defined architectural context, with the emphasis on a spatial experiences and aesthetics. We explore new emergent fabrication techniques together with a “poetic” concept of a memory and adaptation.

The mobile telecommunication network is growing year after year and it will soon move into the high speed 5G and Internet of Things technology. These new technologies will improve the throughput and data connectivity and due to that the energy consumption in radio and digital units may increase in a Radio Base Station (RBS). There are more than 500 000 off-grid RBSs in the world which are powered

Ni-Ti systemet har en stor mängd tillämpningar, inom områden så spridda som biomedicin och robotteknik. Detta beror till stor del på den intermetalliska föreningen NiTi, vilken är en minnesmetall. Utöver denna egenskap är den intermetalliska föreningen dessutom biokompatibel, har bra mekaniska egenskaper och god resistans mot korrosion. Studier på NiTi har visat att temperaturerna kopplade till deThe Ni-Ti system has a broad range of applications, in areas as diverse as biomedicine and robotics. This is in large due to the NiTi intermetallic compound, which exhibits the shape memory effect. In addition to this property, the intermetallic compound is also biocompatible, has good mechanical properties and good corrosion resistance. Studies on NiTi has shown that the temperatures at which the

The construction sector is one of the biggest contributors to global CO2 emissions and buildings account for a significant part of the energy use in Sweden. Population growth in combination with economic development is putting more pressure on the environment, resulting in escalating consumption trends and larger quantities of raw material extraction. Policies and directives are promoting a circul

A confocal microscope is built to examine molecular powders, and in particular the (PhSn)_4S_6 cluster, that emits white light when irradiated with infrared laser light. The confocal microscope operating at long working distances is assembled and characterized. The components of the setup are first chosen according to requirements of the planned experiment. Thereafter, the microscope is assembled

Det här arbetet ger en enkel introduktion till teorin för så kallade Lie-grupper (uppkallade efter den norske matematikern Sophus Lie), som är en slags matematiska objekt som befinner sig i gränslandet mellan två av matematikens huvudområden: geometri och algebra. Å ena sidan kan Lie-grupper betraktas som släta mångfalder, vilket betyder att de är kurvor, ytor eller högre-dimensionella analoger In this work, we present some of the basic concepts and constructions in the theory of matrix Lie groups. For each matrix Lie group, we use the matrix exponential to construct a Lie algebra, and we then use the matrix exponential to show how different properties of the Lie group affect the Lie algebra and vice versa. In particular, we use the Baker–Campbell–Hausdorff formula to prove a one-to-one

The sexual assaults reported on New Year’s Eve 2015 in Cologne and the reactions towards it have changed political and public opinion on the issues of migration, gender equality, and sexual violence in Germany. Based on theories from postcolonial studies, feminist studies, security studies, approaches on collective trauma, and emotion studies this thesis analyzes ‘Cologne’ as a trauma which has en
