Vad har känsla av sammanhang och upplevt socialt stöd för samband med individens sinnestämning
The aim of this study was to examine the relations between sense of coherence (SOC), perceived social support and mood, the study also included gender and civil status in the analysis. In the analysis mood was the dependent variable. The study included 81 respondents, all students from Växjö university, who answered a survey with three parts: SOC 13, Mood Adjective Checklist (MACL), and an own constructed instrument that measured perceived social support. The result showed that those with a high SOC tended to have a greater mood. High scores on perceived social support also were related to a greater mood.

Abstract Title: High-Risk Funds vs. Mutual- Index FundsA study of macro -variables influence on different funds choice Level: Final assignment for Bachelor Degree in Business Administration Author: Moses Yokie & Bo Lemar Supervisor: Ogi Chun & Cheick Wagué Date: 2011-05-25 Aim: The purpose with this thesis is to compare two different types of mutual-index fond and a high-risk fund in relation to the macro variables. The purpose also includes an investigation about if an investor will receives a higher return on high-risk fund than on mutual-index fund in a 10 years period.Method: A quantitative method has been use in this study, where the information has been received from Morningstar. Microsoft Excel has been used to process the collected data in order to calculate the expected return and the risk measures. The result is presented in graphs and tables on the empirical capital, in order to analyse and compare it with the theories and the selected macro- variables to see if there will be any correlation. Conclusion: This research shows that there is no possibility that the macro-variable factors can benefit an investment on high-risk fund or on mutual-index fund in the short run.
Sannolikheter i fotbollsmatcher : -Kan man skapa användbara odds med hjälp av statistiska metoder?
Betting under ordered forms has been around for a long time, but the recent increase in Internet betting and the large sums of money that are now involved makes it even more important for betting companies to have correct odds. The purpose of the essay is to calculate probabilities for outcomes of football games using a statistical model and to see if you can find better odds than a betting company.The data contains the 380 games from the 2004/2005 season and the variables form, head-to-heads, league position, points, home/away, average attendance, promoted team, distance and final league position from previous season. After performing an ordered probit regression we only find the variable ?form of the away team? to be significant at the 5 % level. We suspect the presence of multicollinearity and perform a VIF-test which confirms this. To fix this problem we perform a second ordered probit regression where a number of variables are combined to index variables. In the second regression we once again find only one significant variable.
Rökgaskondensering och skrubber till vedeldade villapannor :
This paper deals with the opportunities for the technique of condensation, for wood fired household heaters, on the Swedish market. In this project the condenser is preceded by a scrubber and both energy exchange and separation of unburnt particles have been studied.
The facility studied is connected to a wood stove at 30 kW. The tests would show that the effect from the stove never reached above 16 kW. This might be a result of the low temperature of the water going into the stove, from the condenser. In addition to this the wood was not of highest quality and the stove could have needed some maintenance before the tests.
Har analytikernas roll på aktiemarknaden blivit mindre relevant: En studie av analytikernas påverkan på aktiers avkastning
The purpose of this thesis is to investigate if the stock market reacts differently to accounting information, depending on the stock market climate. The study focuses solely on stocks listed on the OMX Stockholm 30 during each year from 2005 to 2009. By applying the concept of Earnings Response Coefficient we can estimate how the market reacts to accounting information. The dependent variable in the equation is the market reaction on unexpected earnings, in the study described as the abnormal return on stock. For quality purposes we measure this on a ±1,5,10 and 20 days basis.
Hur påverkas aktiemarknaden av räntan, valuta- och obligationsmarknaden? : En empirisk studie under perioden 2005-2009
Introduction: Interplay between all the different subsystems of the financial markets is currently considered as an important internal force in the market. In a financially liberalized economy exchange rate stability is a basis for a wellbeing stock market. If these interactions between all the different subsystems of the financial markets are not detected, this means that there is information inefficiency in the markets.Problem: Can we find any correlation between changes in currency, interest rate and bonds with the stock market index? If so, how do these changes affect the Stockholm Stock Exchange?Purpose: The purpose of this study is to examine if there is any linkage between the interest rate, currency and bonds with the stock market. The researchers wanted to find out how these variables affect the stock market index OMX S30 which consists of the 30 largest companies on the Stockholm Stock Exchange.Method: This research has been based on a quantitative approach.
Bottensubstrat och dess inverkan på reducering av BOD5, COD och TKN i lakvatten genom konstruerade rotzonsanläggningar : En pilotstudie vid Univates, Lajeado ? RS Brasilien
Treatment wetlands been showed efficient for reducing pollutant in waste water. In Lajeado ? RS, Brazil the landfill has poor leachate water treatment. It is necessary to supplement the treatment plant because they need to reduce BOD, COD and nitrate of the water going to recipient. A subsurface flow wetland (SSF) can be a good choice. In order to be able to design an efficient SSF it is important to understand how the grain sizes of a substrate affect the reducing of pollutants in waste water.
Trafikstyrning med variabel trafikutrustning : en behovsanalys för Vägverket Region Stockholm
When traffic in large cities increases, it becomes more vulnerable to disturbances such as accidents, stalled vehicles or construction; therefore, traffic jams are more likely to occur. For better control of the traffic at a disturbance the Swedish National Road Administration (SNRA) has traffic equipment which can be controlled from a command centre. This traffic equipment consists of gates and signs with variable messages. This report will discuss the system used for traffic control in Stockholm. It will present proposals designed to improve it.
When you ain't got nothing, you've got nothing to lose : En kvalitativ studie om stigmatiserade individers möjligheter att återinträda i samhällsgemenskapen
Denna uppsats behandlar ett antal stigmatiserade individers möjligheter att återinträda i samhällsgemenskapen efter ett liv i missbruk eller på institution. Detta har skildrats genom individernas livsresa, från inspärrning/inskrivning på totala institutioner till det vakuum som uppstår när de blivit frisläppta eller utskrivna, och vad de därefter har för möjligheter att förändra sin identitet och bli en del av samhällsgemenskapen. Vi har inriktat oss på en verksamhet, som fångar upp personer i ett mellanläge, efter inspärrning men före samhällsintegrering. Verksamheten har till skillnad från statliga behandlingsverksamheter en acceptans för Harm Reduction. I tidigare forskning har vi beskrivit missbruksvården och den svenska narkotikapolitiken.
Hur påverkasogräsuppkomsten av jordbearbetning :
Today it is common to spray against most weeds by using very expensive weed-killers.
The goal for every farmer is to have as low costs as possible for their use of machines and weed-killers.
Therefore it is in everyones interest to find other methods to fight the weeds.
Finding a way to reduce the rise and growth of weeds already at the preparation of the soil would lower the number of laps over the field and also decrease the amount of weed-killing dose.
Tests show that by harrow in the dark it is possible to reduce the population of weeds with up to 60%, but the normal reduction would be about 20-30%.
To verify the results above we made tests by using two different methods of preparing the soil. We tested ploughing and harrowing in daylight and during night. Later we checked the number of different weeds in areas prepared in daylight and during night.
By studying the results from the different methods used we found a considerable reduction of some kinds of weeds in areas prepared during night..

E-learning ? en utbildningsmetod och dess nytta
Companies that invest in e-learning have different expectations regarding the outcome of the investment. According to literature and articles it is common that companies see reduction of costs as the primary benefit with e-learning. Therefore we ask ourselves the question if companies have attained the expected benefit of the investment in e-learning and to what extent cost reduction have been a determining factor in the investments? The purpose of the thesis is to examine if companies that invest in e-learning have attained the expected benefits. We also want to examine what the reason for investing in e-learning is and if cost reduction is the primary reason for investing.
Undersökning av affinitet till TS1-218, TS1-2182 och HE1-Q enkelkedjeantikroppar i multicellulära tumörsfäroider cytokeratin 8 för TS1-218, TS1-2182 och HE1-Q enkelkedjeantikroppar i multicellulära tumörsfäroider
In vitro-test för upptäckt och behandling av tumör eller mikrometastaser har de senaste 30 åren gjort stora framsteg tack vare immunokemi och nya framgångsrika cellodlings- tekniker som bättre reproducerar celltillväxt i tre dimensioner (3D) och det omgivande stromat (multicellulär tumörsfäroidodling). TS1-218 scFv (single chain variable fragment) är en monoklonal antikropp som har affinitet till ett protein tillhörande cytoskelettet (cytokeratin). Av TS1-218 har skapats olika varianter (en dimer TS1-2182 och en mutant HE1-Q) med syftet att öka affinitet och retentionstid på platsen för dess verkan. I det här projektet försökte vi att testa och jämföra egenskaper hos alla 3 joderade antikropparna genom att inkubera odlade Hela Hep 2 tumörcellssfäroider med dessa antikroppar. Alla tre antikroppsvarianter visade god förmåga att penetrera sfäroider och att binda deras epitop i cytokeratin 8.

De svenska börsbolagens prioriteringar mellan investeringspolitik och utdelningspolitik : En studie av sambandet mellan investeringspolitik och utdelningspolitik i förhållande till börsvärde
The relationship between dividend policy and investment is a controversial area and the relationship between these two may differ depending on the company's priorities. The study examines this more closely by studying dividend policy's impact on investment and how it differs depending on the company?s market capitalization. The study is based on companies listed on the OMX Stockholm within the segments Large Cap and Small Cap, during the period between 2003-2012. Secondary data was obtained from each company's annual reports where relevant data was used to operationalized into measurable variables.
