In this thesis, Twitter data is used to predict the intraday stock return for Tesla, Inc. We present two different methods to extract the tweets’ sentiment: A dictionary-based approach (VADER) and a machine learning approach (SVM). Additionally, we control for other dimensions as the user and discussion dimension. Then a Granger causality test and a lasso regression are conducted on a one- and fiv
Sverige har över tid mött kritik för långa häktningstider och omfattande användning av restriktioner, främst isolering. Uppsatsens syfte är att undersöka vad det är som gör att just Sverige sticker ut jämfört med våra grannländer. För att uppfylla uppsatsen syfte har gällande rätt sammanställts för de tre länderna, Sverige, Danmark och Norge, med hjälp av den rättsdogmatiska metoden. Dessa har seSweden has over time faced criticism for its use of restrictions, such as isolation, for remand prisoners and also the long times that suspects are being held awaiting trial. The purpose of this paper is to investigate what makes the Swedish justice system stand out when compared to fellow Nordic countries. To fullfil the purpose of this paper Sweden’s, Norway’s and Denmark’s legislations have b
Current methods for analysing cellular content require lysing the cells. This can be a drawback when there is a desire to study dynamic processes in the cell as the cells die during the lysis process, and a study over time is not possible. One such example exist inthe field of molecular biology, where diabetes researchers desire to study the insulin geneexpression of beta cells over time, and its d
Molecular properties of spin crossover complexes [Fe(CN)6]4-, [Fe(CN)6]3-, [Co(CN)6]3- and [Co(CN)6]2- were computed using quantum chemical computations at Density Functional Theory (DFT) level of theory to examine how nuclear charge, oxidation state and electron configuration influence energy levels of MC and CT states of the compounds. Across the series, the MC states of the compounds were found
Cua Lo river mouth is a coastal inlet connected to an estuary at the central coast of Vietnam. The area is valuable for maritime trade, fishing industries, and tourism development. Natural disasters during the monsoon period are a problem, causing seasonal flooding. In connection to the inlet lies an elongating sand spit which causes erosion and destruction of residential areas on one side of the
Metal-organic frameworks (MOF) are hybrid organic-inorganic porous materials with a crystalline framework. The MOF frameworks contain specific nano-sized pores that can be used for gas storage, gas separation, drug storage, luminescence sensoring, artificial photosynthesis, drug delivery, catalysis etc. The aim of this study was to encapsulate three diiron hexacarbonyl and one Ni(II) catalysts in
Pentaklorfenol (PCP) är en klorerad aromatisk förening som användes flitigt för att behandla trä mot mikrobiell nedbrytning innan den blev förbjuden på 70-talet. På grund av dess höga löslighet förekommer PCP som en grundvattenförorening kring äldre sågverk. Hjortsberga i södra Sverige är ett exempel på denna typ av förorening och är det område som undersöks i arbetet. Förorenat grundvatten spridsPentachlorophenol (PCP) is a chlorinated aromatic compound that was commonly used for treatment of wood against microbial degradation before it got banned in the 1970s. Due to its solubility in water, PCP is a common groundwater contaminant around old sawmills, for example near Hjortsberga in southern Sweden where this study was performed.. The contaminated groundwater is spreading and leaking int
Vi har i vår studie undersökt hur chefer talar om och beskriver motivation i arbetssammanhang. Vi har även studerat hur den egna förståelsen av motivation återspeglas i hur chefer resonerar kring och arbetar med andras motivation. Våra forskningsfrågor var följande: Hur reflekterar och talar chefer kring motivation i arbetssammanhang? och Har den egna uppfattningen av motivation någon betydelse el
The low-carbon benefits and emissions savings from circular economy (CE) strategies are not yet well understood, yet are crucial for global development within Planetary Boundaries. Using the mineral fraction of waste incinerator bottom ash (MIBA) as construction material in road construction is one application of a CE strategy that could lead to environmental gains by substituting energy-intensive
This explorative case-study examines the dynamics of operationalizing climate change adaptation (CCA) measures in the aftermath of climate change induced natural disaster at the community level in a low-lying coastal Nation State with fragile institutional capacity. It explores the roles and responsibilities different stakeholder groups take and identifies constraints and facilitators for operatio
This thesis focuses on the case study over the Kävlinge catchment located in the south of Sweden, and mainly in the Kävlinge river. This river, which is the mainstream of the catchment, has been subject to modifications due to agricultural activities. Such modifications, like straightening or increasing the depth and channeling sections of the river, will affect the river’s hydrodynamics. These in
The pentadentate ligand 2-(pyridine-2-yl)-N,N-bis(pyridine-2-ylmethyl)quinoline-8-amine was isolated and characterized. Mononuclear iron(II) complexes of the ligand have been synthesized and characterized. Three iron complexes, [Fe(CH3CN)L1][OTf2], [Fe(OTf)L1] and [Fe(Cl)L1][Cl6Fe2O] (L1 = 2-(pyridine-2-yl)-N,N-bis(pyridine-2-ylmethyl)quinoline-8-amine) (OTf = triflate, trifluoromethane sulfonate)
The concept of industrial symbiosis (IS) provides practical solutions for resource efficiency and low-carbon development. The IS represents a collective, multi-industrial approach for companies to improve their economic and environmental performance through the sharing of heat, electricity, water, by-products, information, and reuse of waste. The main challenges to IS emergence include a long dura
Dibenzo[a,e]cyclooctatetraene or dbCOT is a commonly used ligand in transition metal catalysis. Moreover, the Strand group has been using its properties to change shape (from tub-shaped to planar and vice versa upon reduction/oxidation) to develop novel molecular machines. However, the use of dbCOT in both transition metal catalysis and as a building block for molecular machines has been limited b
Denna uppsats utreder huruvida det går att identifiera en särskild rättsordning vad gäller fördelningen av internationellt ansvar mellan EU och dess medlemsstater under blandade avtal, det vill säga internationella avtal som undertecknats av EU och vissa eller alla dess medlemsstater på ena sidan, och en tredje stat eller internationell organisation på den andra. Uppsatsen presenterar slutsatsen This thesis examines whether there exists a special legal regime for the apportionment of international responsibility between the EU and its Member States under mixed agreements. The thesis argues that the sui generis aspects of the EU, such as its constitutional order, its international legal personality, its extensive treaty-making powers, legislative powers, its executive federalist construct,
In this thesis I examine the metapolitics of the French far right, a sphere of organisations and personalities that are waging a counter-hegemonic cultural fight, thought to be a precondition to political change. In France, singularly an incubator for a green nationalist narrative, this “Gramscianism of the right” is today embodied by countless media outlets. This research, grounded in a socio-con
Geologisk tid är inte bara ett tröskelbegrepp, det är en central del i hur vi erfar geovetenskapliga fenomen som utspelar sig på en rumtids-skala som sträcker sig från mikro (exempelvis molnbildning) till makro (exempelvis plattektonik). Om vi vill förstå geovetenskapliga fenomen måste vi gå från det konkreta till det ab-strakta, vi måste gå från att kunna se och ta på fenomen till att enbart kunnGeologic time is more than a threshold concept, it is a central part of how we experience geoscientific phenomena that takes place on a space and time scale ranging from micro (e.g. cloud formation) to macro (e.g. plate tectonics). If we want to understand earth science phenomena, we must move from the concrete to the ab-stract, we must go from being able to see and touch a phenomenon to being abl
This essay explores which sector of the Swedish economy has benefited the most from changes in the exchange rate during the period 1997-2018, which was a time of depreciation. Branches from two-number SNI (Swedish National Industrial Classification) are categorized into three main sectors: services, primary industry and remaining industry, and then matched with SITC data on imports and exports. It
Dammutrivningar har kommit att bli ett alltmer aktuellt ämne efter att nya regler om miljöprövning av vattenkraftverk införts. Syftet med reglerna är att dessa dammar ska få moderna miljövillkor. Detta ska bidra till att de svenska miljömålen uppnås, samt att kravet i EU:s ramdirektiv för vatten avseende god ekologisk status för vattendrag uppfylls. Utöver detta är det troligt att uppmärksamhet riThe subject of dam removal har become increasingly relevant since new regulations concerning environmental impact assessments of waterpower stations. The purpose of this study is to investigate and describe the consequences associated with real estate law that can arise from dam removal, and to review the judicial/legal regulation on dams. A literature study has been conducted, to interpret and sy
