Kvävemineralisering från stallgödsel beroende på olika grad av inblandning i mark
The impact of the distribution in the soil volume of two farm manures on the net mineralization and immobilization processes of nitrogen were studied in an incubation experiment. Cattle slurry and broiler litter were placed in the soil with three procedures for incorporation including placement on top of the soil (TOP), in the middle of the soil (MID) and mixed homogenously with the soil (MIX). During the two weeks of incubation, few significant differences in net mineralization were seen between TOP, MID and MIX. However, there was a tendency that MIX led to a larger net immobilization of N than placement at one point (TOP and MID). This is also the result in the literature.
Småföretagsfördelar vid tillväxt
Growth of small businesses is vital to the Swedish economy, and many entrepreneurs want their enterprises to grow. However, the business climate of today is more changing than ever, and attributes becoming increasingly important for companies in order to deal with this are flexibility, speed, and adaptability: characteristics normally attributed to small enterprises. As a larger organization often is associated with more rigidity as a consequence of a higher degree of formalization, entrepreneurs are hesitant to seize growth opportunities, as they fear it will have negative impact on the aforementioned competitive advantages their enterprise possesses as a small business. This simple case study of a growing small enterprise investigates the effects of organizational growth on a small business' organizational structure and through its above mentioned advantages. The study finds that avoiding formalization while growing damages the competitiveness of the firm, and concludes that a degree of formalization is a necessity to maintain the flexibility, speed and adaptability in a growing small business..
Innovate or Evaporate : -En kvalitativ studie av idéhantering på IKEA AB
The thesis focus on how organizations can improve the ability of absorbing coworkers ideas in purpose of gaining long term competitive advantage through innovations. The study was conducted at IKEA AB where a campaign to collect coworkers ideas was a big success given the quantity of ideas collected. This fact allows a comparative analysis of idea management in the shape of campaigns and in comparison, idea management in the everyday line-organization.The analysis show that fundamental factors for innovative environments such as organizational climate, culture and leadership perceives auspiciously by the respondents. However, lack of infrastructure such as systems and processes hinders coworkers ambitions to contribute with ideas.An important issue in idea management is the treatment of incentives for innovation. Results of the study show that the ?soft? incentives ?feedback, encouragement and attention have a higher impact in coworkers willingness to the contribution of ideas than for instance monetary rewards..

Chicago Area Project - ett exempel på hur deltagardemokrati kan genomföras?
There are lots of theories about participatory democracy, but rather few examples of how to create it in practice. In the 1930´s, scientists at the Chicago School, implemented some projects within the Chicago Area Project, with the aim to decrease the youth delinquency in the socio disadvantaged areas surrounding Chicago. In this thesis, I assess wether these projects, and in particular the one at the Russell Square Area, have some common features with the thoughts of two of the most famous participatory democrats, Carole Pateman and Benjamin Barber. My question is if the Chicago Area Project could be seen as an experiment in participatory democracy. I find that participatory democrats could benefit from the experiences of the Chicago Area Project.
Kartläggning av omställningsarbete vid formspruta
This study will chart the changeover work, with a standpoint in the SMED-theory, at the company Peter Ernst AB in Värnamo. They are suppliers in plastic moulding industry and delivers to amongst other Saab in Trollhättan and Scania. The company are in a very competitive market, and they have to make manufacturing more efficient and rationalise their costs to be able to compete. A big problem, which the company has identified, is their long changeovers. It brings higher costs, a more stressful work climate and holds back the company from becoming more efficient.Field studies will be conducted on the changeover, which will be observed and filmed.

Allvarlig lek : Ett experiment i att ta träningsmoment i underhållningsspel på allvar
Detta examensarbete är en undersökning i hur riktlinjer anpassade för Serious Games-genren kan användas i utvecklingen av träningsmoment till ett simpelt kooperativt plattformspusselspel. Undersökningen baserades på en analysmodell vid namn RETAIN (Relevance, Embedding, Transfer, Adaptation, Immersion, Naturalization) vilken utvecklats specifikt för att analysera och hjälpa till vid utvecklingen av inlärningsspel. Denna modell har använts för att analysera plattformspusselspelet Braid, varefter analysen har använts som riktlinjer under utvecklingen av ett eget verk. RETAIN-modellen har även använts för att analysera det egna verket.Efter undersökningen har jag kommit fram till att RETAIN-modellen i sitt originalutförande ej lämpar sig för utveckling av träningsmoment i underhållningsspel då kraven på spel i Serious Games-genren och underhållningsspel är alltför olika..
Priming av självrelevanta ord : Kan attributionsstil påverkas av omedvetna signaler?
Människor tenderar att attribuera framgångar till sig själva och misslyckanden till externa källor, fenomenet kallas för Self-serving bias. Hur individer attribuerar kan enligt forskning påverkas av bland annat graden av självkontroll samt självkänsla. Enligt forskning kan intentioner eller beteendemål aktiveras automatiskt och omedvetet av en utlösande signal, så kallad priming, och därmed aktivt guida en persons självreglering. Denna studie har genom ett experiment, med 56 högskolestudenter, undersökt om priming av självkontroll och självförtroende kan påverka hur en individ attribuerar vid framgång och misslyckande. Resultatet visade ingen signifikant skillnad mellan priminggrupperna.
Hur lokal bioenergi kan bidra till att Uppsala kommun når klimatmålet 2050
The purpose of this thesis was to examine how locally produced bioenergy may contribute to meet the climate target year 2050 in the municipality of Uppsala. The
goal of reduced GHG-emissions from current 6,8 ton CO2-equivalents to 0,5 ton CO2-equivalents per capita and year, year 2050 is based on avoiding harmful penalties
of an increased level of GHG in the atmosphere. By estimating available biomass in the county together with examining future technologies and emission factors for the substrates used, four possible future scenarios has been developed focusing either on electricity generation or production of biofuels. GHG-emissions of year 2050 have been calculated using the software LEAP.
The conclusion is that bioenergy, depending on how it is integrated in the energy system, may reduce greenhouse gas emissions between 0.6 ton CO2-equivalents and 1.4 ton CO2-equivalents per capita or 12% to 25% compared to 5.5 ton CO2-equivalents in the reference scenario 2050. The greatest reduction is obtained if biofuels are produced in combination with energy efficient heat requirements in
buildings..
