De Paard - Visions of Playtopia

Playsam in Kalmar AB are world famous for their design of the toys they sell. Together with their CEO Carl Zedig the goal was to find a new product for the company.  The process has far from been linear, I started off in one direction, got rejected, turned another way and we finally decided to create a rocking horse in a De Stijl style. At the same time taking consideration of the demands from Playsam and myself.Playsam?s products are archetypes of ordinary objects around us such as the car or the aeroplane. The company mainly produces its toys in wood and the stylized shape together with the blank painted surface has become a hallmark for them.De Stijl, the Dutch art movement containing artists, designers and architects such as Piet Mondrian, Theo van Doesburg and Gerrit Rietveld.

Transferfunktionsmodeller modellering och prognoser av Sjötransportindex

We have by Statistics Sweden (SCB) been given the task of using different dynamic regression models in order to forecast service price index for sea transport. The aim is to see whether these models provide better forecasts than those previously used. This essay aim to identify, estimate and evaluate the selected prediction models. Through our data material we were given access to 28 sightings of sea transport index during the period of 2004 q1 to 2010 q4. We have chosen to evaluate three different transfer function models, one ARIMA model and one naive forecasting model. The input variables we decided to test in our transfer function models were the price of petroleum products, the port activity in Swedish ports and the lending rate of Swedish Central bank. The results of our study suggest that transfer function models generally provide better models than the ARIMA model and the naive forecast model.

Ekonomisk tillväxt och utländska direktinvesteringar i Sub-Sahara

The Sub-Saharan countries have for a long time struggled with poverty and conflicts which might have proven hostile for investors. The analysis aims to see if there is a significant correlation between foreign direct investments (FDI) and economic growth and which cultural and institutional factors seem to be significant in this correlation. Considered are also other variables and their influence that might explain what motivates and gives incentives for foreign direct investments (FDI) and are used in the construction of a regression analysis. This to see whether there is an effect on the economic growth in relations to FDI. The results show that FDI is of significance to the economic growth in the region and the study shows that corruption seems to be the most significant institutional factor in the correlation with effect on economic growth and the ability to attract FDI..

Hur ofta hälsar du på din granne? : En kvantitativ studie av integration som förklaringskraft beträffande befolkningssammansättning och radikala högerpopulistiska åsikter

A logical cause of migration is of course immigrants which is a topic always creating discussions. When arriving in a new country a process of integration with the goal to adapt to the environment is started. This study will explore the need for integration and seeks to examine the connection between population composition and radical right opinions.To fulfill the aim, a multivariate regression analysis is done on aggregated level in Sweden with statistics concerning the year of 2010. The relation between ethnic composition and voters support for the Swedish radical right party Sverigedemokraterna is studied as well as integration as an explanatory intermediate factor operationalized through unemployment, financial assistance and trust.The results of the study indicate a positive connection between immigrants from EU/EFTA and the voter support for Sverigedemokraterna. A negative relation is identified between trust and the voter support for Sverigedemokraterna.

Ekonomisk tillv?xt och lycka

This thesis investigates the relationship between economic growth and self-reported happiness in 45 European countries during the periods of 2011 and 2014-2022. In addition to economic growth, the effects of factors such as unemployment, health, and equality are also analyzed. Data has been collected from the World Bank and Our World in Data. To analyze these relationships, a fixed effects regression analysis and clustering are used, supplemented by tests for multicollinearity and scatter plots. The results of the study indicate that economic growth has no significant effect on happiness when our control variables are included in the analysis.

Visuell men inte auditiv och olfaktorisk föreställningsförmåga predicerar med kreativitet

Syftet med föreliggande uppsats var att undersöka relationen mellan olika typer av föreställningsförmåga (visuell, olfaktorisk, auditiv samt visuell bildkontroll) och kreativitet hos vuxna. Ett bekvämlighetsurval genomfördes med 86 deltagare. Instrument för självskattning av mental föreställningsförmåga i de olika sinnesmodaliteterna samt för visuell bildkontroll och kreativitet användes. En multipel regression genomfördes och en närmare granskning visade att endast visuell föreställningsförmåga signifikant predicerade poängen på kreativitetsskalan. Visuell bildkontroll låg precis över gränsen för att vara signifikant.

Angrepp av snytbagge och svart granbastborre i Norrland : skadeläget på SCA's marker en vegetationsperiod efter plantering

Snytbagge (Hylobius abietis L.) och svart granbastborre (Hylastes cunicularius L.) är två allvarliga skadegörare i skogsplanteringar. Det har beräknats att om inte nysatta plantor kan skyddas mot snytbagge skulle angreppen årligen kosta skogsbruket i Sverige mellan 0,5 och 1 miljard kronor som en följd av dyrare föryngringar och minskad skogsproduktion. Tills nyligen visar den praktiska erfarenheten att skadetrycket från snytbagge i Norrland avtar norröver och med ökande avstånd till kusten. Under de senaste åren har dock SCA?s skogspersonal tyckt sig se allvarligare angrepp i Norrlands inland av snytbaggen.

Dikesavståndets inverkan på såtid och skörd

All arable land in Sweden need a proper drainage for an effectively agriculture to take place. Of all arable land in Sweden, about 50% is naturally drained and 50% need artificial drainge. More than half of the tile drained area is in need of new drainage or renewed drainage. A good drainage improves farming and crop growth and increases the opportunity to achieve a high and safe harvest level. Future climate change and agriculture size rationalization will increase the need for good drainage. In this paper, two trials with three drainage distances, performed at Lanna experimental station, were analyzed using a mixed linear model.

Riskpremie i UIP - möjlighet till cross-currency arbitrage? - en jämförande studie av ränta och växelkurs mellan Storbritannien, Tyskland och Sverige.

The thesis explores the Uncovered Interest rate Parity (UIP) and the possibility of cross-currency arbitrage between England, Germany and Sweden. The data is gathered between May 1999 and December 2005 on a monthly basis and is compared using simple regression analysis. The aim is to find out whether UIP holds and, if it does not, a risk premium exists that makes it possible to make arbitrage gains on moving capital between England, Germany and Sweden. It is discovered that UIP does not hold and that cross-currency arbitrage possibilities exist. In the end a an attempt is made to practically show how the arbitrage possibility could be used for a real investor to make risk free gains from the Foreign Exchange market..

Direktavkastningens determinanter

Syftet med uppsatsen är att belysa i vilken utsträckning valda faktorer påverkar direktavkastningen i Sverige samt att klargöra huruvida investerare kan använda faktorerna i syfte att uppnå önskad utdelningsnivå. Metoden som har använts är kvantitativt baserad, den empiriska datan är företrädesvis insamlad från databasen Six Trust, tillhandahållen av LINC vid Lunds Universitet. Angreppssättet har varit deduktivt, där teorier har testats genom multipel regressionStudien visar inte på något entydigt signifikant resultat för de undersökta variablernas förklaringsgrad på direktavkastningen. Resultatet motsäger därmed ett flertal erkända forskares tidigare resultat, däriblad kan nämnas John Lintner(1956) som menade att utdelningen i mycket stor utsträckning kan förklaras av företagens vinster, något vi inte finner stöd för. Vid prognosticering av utdelningsnivån hos svenska börsföretag bör undersökta variabler inte ligga till grund för placering..

Willingness to pay for improved maize seeds among smallholder farmers : a study of the input factor market in Kenya

Kenya is considered to be a developing country. This means that basic needs such as nutrition are not met for an extended period of time (www, Sida 1, 2012). Approximately half of the population is living under the poverty line (www, CIA 1, 2012). Agriculture is the largest sector in the country, employing 75% of the population. These are thereby directly dependent on the sufficiency of outputs received.

De stenbundna skeppen i tra?dens skugga : En studie kring skeppsformade monument fra?n yngre bronsa?lder pa? O?land

Ship formed monuments from the Late Bronze Age on the island of O?land, southeast Sweden, have never been thoroughly dealt with in previous research, despite the fact that the region is suggested to have had a key-role in maritime trade networks. This thesis aims to address the ship formed monuments on O?land in relationship to the monuments in northern Sma?land and the island of Gotland. My goal is to discuss how the ship symbolism was practised during the Late Bronze Age in Scandinavia from a new perspective.

Faktorer som förklarar innovativt beteende hos medarbetare

I en föränderlig värld är det viktigt att snabbt möta skiftande krav ochatt medarbetare är initiativrika, menar både företagare och forskare.Medarbetare som gör mer än plikten kräver och tar egna initiativ,uppvisar Innovative Work Behaviour (IWB). Syftet med studien varatt undersöka om organisationsfaktorerna autonomi, öppet klimat ochrolltvetydighet kan förklara variationer i IWB, med hänsyn taget tillen individuell faktor. Samtliga variabler mättes genom ettfrågeformulär online i ett stickprov om 119 personer.Korrelationsberäkningar visar att samtliga organisationsfaktorer harsignifikanta samband med IWB. En regressionsanalys visar att det ärindividfaktorn som har störst prediktionskraft, följt av öppet klimat,autonomi och bakgrundsvariabeln personalansvar. Studien visar attbåde personlighet och villkor i arbetet har betydelse för IWB..

Qualities and supply of suitable dead wood for Ceruchus chrysomelinus and its dispersal pattern in a translocated population

The wood-living beetle Ceruchus chrysomelinus is a rare species connected to natural forests. In Sweden, it is red-listed as endangered (EN) and an action plan for its preservation has been done by the Swedish Environmental Protection Agency. In this work I have therefore investigated how a translocation of the species succeeded after 17 years. I aimed to study the species dispersal biology, its substrate preferences and the supply of suitable wood on this site. The study was performed during 2012 in Pansaruddens nature reserve close to Uppsala in Sweden, which is a spruce dominated forest.
