Landskapsplanering ur ett hållbarhetsperspektiv :

Environmental problems are accelerating with energy consumption and the release of greenhouse gases as the major issues. This affects landscape planning mostly through environmentally hazardous transportation and heating of buildings. In environmental work, the term "Sustainable development" is often used. This term was coined in the Bruntland report in 1987. A number of frameworks have been developed to clarify the term and to remind the user about relevant aspects of sustainability.

Effekt av sönderdelningsgrad och planteringsdjup på uppkomsten från rhizom av Tussilago farfara :

Tussilago farfara, coltsfoot, is a troublesome perennial weed with deep lying rhizome, which can vegetatively generate new plants. The mechanical control of coltsfoot that is used today, "starvation", which consists of several cultivations of the soil, which fragmentises the rhizome. This results in production of new shoots, which leads to depletion of nutrient resources; as long the new plant is not allowed to establish. However, very little research has been done to investigate how the starving technique affects the regenerative ability of coltsfoot. The purpose of this experiment with coltsfoot was to investigate how fragmentation and burial depths affect the time of emergence, number of emerged shoots per rhizome fragment, number of shoots per node, and if the germination ability within nodes changes during the experiment.

Avgiftens kapitalisering i slutpriset för bostadsrätter - En studie om hur avgiftens kapitaliseringsgrad över slutpriset på bostadsrätter i Vasastan/Norrmalm förändrats mellan 2006-2014

Prior studies have shown the relationship between capitalised monthly fees and sales price for tenant-owned apartments in Stockholm. However, few studies have been conducted explaining the effects of capitalised monthly fees over time and how it has changed with, for in-stance, increasing sales prices and fluctuating interest rates. The aim of this study is to deter-mine if the effect of capitalised monthly fees on sales prices of tenant-owned apartments has changed between 2006 and 2014, in Vasastan/Norrmalm in Stockholm. The study shows that there are statistically significant results indicating that capitalised effect of monthly fees on sales prices has in fact changed over the studied time period. The results differ with apartment size (number of rooms) and the conclusion is that there is an effect of time on one, two and three bedroom apartments but not for apartments with four bedrooms or more..

Röjningsformen och stamantalets effekt på höjd- och diametertillväxt i toppröjda och konventionellt röjda tallbestånd.

Topping is a precommercial thinning (PCT) method where secondary stems are cut higher above the ground compared to conventional PCT. The secondary stems continue to live for a period and are supposed to compete with the main stems and promote their quality.The objective of the study was to compare the effect of PCT on height and diameter growth between topping and conventional PCT. The study also analysed the relationship between height and diameter growth and the number of stems after PCT.Nine topped stands and six conventional precommercially thinned stands were visited between February 28th and March 5. One sample plot per hectare was laid out in the investigated stands. In every sample plot the number of stems was counted and five main stems were measured for height, height growth since PCT, diameter and diameter growth since PCT.The results showed significantly higher effect on height growth after topping as compared to conventional PCT but no significant difference in the effect of diameter growth between topping and conventional PCT.

Passivhus av helväggselement i träull

Environmental destruction is a growing problem in our world. Almost every day there are new reports concerning that we have to do something about the greenhouse gasses. Simultaneously is the human constantly more eager to have a life with higher standards and therefore uses more energy. The environment is a question that is highly up-to-date and more people try to find solutions on how to save our planet. One way to decrease the energy demand is to build passive houses, where the houses don?t have any active heating.

Frontningens Effekt på Försäljningen och Kundens Utvärdering av Butiken - Ett Experiment i den Naturliga Butiksmiljön

The research done in the field of product completeness/incompleteness is limited. The lack of research causes a knowledge gap in the retailing industry, concerning the actual effects on consumer choice, as well as on the overall store evaluation. This report tests the current theories of the subject, and also further aim to explore the effects of completeness/incompleteness on consumer's product choice. The results display an inconsistent effect on consumer's product choice when the completeness/incompleteness in a grocery store is tested. Some products benefit by being incomplete, while others show no such effect.

Energieffektivitet och kvalitet på inomhusluft i radon förorenade bostadshus

To build a sustainable future should we first understand that; every aspect of our daily lives can affect the environment. It?s important that we take responsibility for understanding how we impact the environment and change our actions accordingly. The worlds total energy consumption equivalent to 80 million MWh / year. This corresponds to about 220 million MWh / day.Energy consumption is one of the main reasons for increased greenhouse gases when the reduction of this consumption has a great demand worldwide.In order to prevent the energy that consumed the buildings must be energy efficient but there is a conflict between radon ventilation and energy conservation in a building, given that ventilation can consume as much energy (currently 29-59% of energy-efficient houses use), especially in a cold climate as in Norway.

The Best Thesis of the Year!: A study on the effect of customer generated ratings in advertising

In this thesis, the impact of collective ratings on customers? perception of a product is examined. The empirical data comes from an experimentally designed survey where the effect of collective ratings is measured in the setting of a traditional advertisement for a feature film. In contrast to what previous research would suggest be to the expected outcome, the authors of this paper concludes that in comparison with alternative designs of advertisements, there are no measurable advantages of including collective ratings in advertisements from the marketers point of view. We find two explanations to the result: (1) people tend to self-report that they are more influenced by collective ratings than they actually are, and (2) the advertisement which lacked a rating could be as attractive due to cultural interpretations of white spaces..

Företagsrekonstruktion och förmånsrättsreformen : Vad är det som gick snett?

Sweden needs a policy that stimulates economic growth. Year 1996 the Business Reorganization Act (1996:764) came into force. The goal with this law was to savebusiness, make it profitable and avoid unnecessary bankruptcies. Shortly afterwards itturned out that the law had no positive effect. A very few numbers of companies appliedfor reconstruction and the number of applications for bankruptcies continued to increase.In 2004, in order to stabilize the situation and bring about neutrality between twoproceedings, company reorganization and bankruptcy, the government proposed thereform of priority rules.

Straff utan Brott : En studie av män som fått sina öron avhuggna i Irak

This is a study of seven men that have suffered from a cruel punishment. The punishment involved getting their ear/ears cut off, prison with more torture and their families being deported from their homes to another town.My sample involved seven Iraqi men who suffered from this punishment during Saddams regime, they got this punishment because they refused to fight against Iran and Kuwait. I went to Iraq and met with the men in person and did interviews with them to understand the effect of the punishment on their personalities, and how the punishment have influenced their lives and interaction with other people in the society and around them.The study focuses on their suffering and how they have been able to live with this stigma. The method the study has used is the kvalitative method that involved interviewing them in their country Iraq and analyse their answers and then come to the results. My study was between 26 of March 2004 to 26 of April 2004.My study is based on the theory of social interaction and especially the symbolic interaction theories of G.H.

Produktplaceringar och påverkan - en kvantitativ studie av produktplaceringar i rörlig media

In the ever increasing media clutter it is hard for marketers to make their products stand out. New ways of reaching consumers are constantly arising. This study seeks to further investigate the phenomenon known as product placement, delimited to movies/television. By conducting an experiment we tested whether different presumptions matters for what effect a product placement will have on attitude and if these could be affected. We also looked at if the level of product integration effect attitude and realism enhancement.

Welfare impact of social breeding value and straw for growing-finishing pigs

Animal welfare is of increasing concern in present society. In commercial pig farming, animal welfare problems are common. One of the causes for these problems is the barren environment in which pigs are housed, which can cause oral manipulation of pen mates. Providing straw might be one solution to this problem. Another solution could be reached through genetic selection.

Transientanalys för Forsmark block 2 och 3 : Studie av hur val av driftpunkt och pumpreglering påverkar torrkokningsgränsvärdet

The dry out criterion (MCPR) has been calculated for the most limiting H2-events for Forsmarks unit 2 and 3, at operating points that are normally not analyzed before each cycle. The operating points that normally are regarded as the ones with the lowest margin to dry out are the ones where the thermal power is the highest at agiven recirculation flow. This report shows that this is not the case for Forsmark 3. MCPR-values at partial power operating points are higher for the limiting case inside rather than on the boundary of the region of operation. It is therefore recommended that the method for determining the dry out criterion for Forsmark 3 is revised to account for this effect.

Värdepremium på den svenska marknaden - En residualvinstvärdering med säkerhetsmarginal

This paper attempts to investigate the correlation of 12 month abnormal returns and the fundamental value of stocks in theSwedish stock market between the year 2000-2011. Also, the paper tries to apply and evaluate the concept of the margin ofsafety. In estimating the fundamental value we use the residual income valuation model and three different estimationapproaches of the beta coefficient in order to correct for financial and operational biases. We find that our different portfoliosearn abnormal returns. However, this could be explained by the size effect and P/B effect.

Samband mellan virulensgener och VTEC-infektioner : Riskklassificeringssystem för VTEC

To curb greenhouse gases and mitigate climate change is one of the biggest challenges human society face today. Carbon dioxide (CO2) has accumulated rapidly in the atmosphere as a consequence of burning of fossil fuels and deforestation. The aim of this study is to explore two methods to store carbon dioxide in geological formations and biological sinks. The aim is also to discuss the two mitigation options from a sustainable perspective and whether it can lead to a better environment and benefits for local and global societies. The research questions are: Which method to store carbon dioxide, geological or biological, is the most effective? Which method to store carbon dioxide, geological or biological, has the greatest potential to promote sustainable development for local communities?The method used is a comparative case study and presents four case studies that explore the potential for CO2 storage offshore in Norway and Brazil; and in tropical forests in Mexico and Brazil.
