Revision av miljöledningssystemen i statliga myndigheter : Utvärdering av ett verktyg i det systematiska miljöarbetet
The Swedish government decided in 1996 that the governmental authorities are to implemementenvironmental management systems. Each year, the Swedish Environmental ProtectionAgency compiles the authorities? reports on their environmental management systems. Thecompilation shows that not more than 20 % of the authorities perform environmental audits.This study aims to investigate the authorities? view of internal environmental audits, the incentivesof performing them.
Biblioteksbloggen ? en studie om realisering av bloggverksamheter vid folkbibliotek
The purpose of this bachelor thesis was to gain a deeper understanding of and examine how library blogs are realized at public libraries together with the views among librarians regarding the realization of library blogs.The questions we wanted to answer were: ? How is the library blog realized at the public libraries in this study? ? What are the views among the librarians in this study regarding the realization of the library blogs?The analytical model in this thesis is Connie Crosby?s six steps on how libraries successfully can realize their blogs. Four of the six steps were selected: planning, implementation, marketing and measures of success. The methodology used for this study was semi-structured interviews. Two interviews were conducted with three librarians that have partial responsibility of their respective library blogs.The results of the study show that the process of the library blog can look different in different libraries, and that the respondents had clear views on how the realization of a blog should be done.
Lantbrukaren som energiproducent : en fallstudie i energisatsningar inom lantbruket
The intrest and development of bioenergy and energy from renewable sources in Sweden has increased rapidly over the last few years. There are a whole lot of alternatives for those who would like to venture and invest in renewable energy production.
Production of renewable energy opens up many opportunities for forestry and farming to venture a new branch of production, on basis of the primary production. Several of the new energy sources grows on farmland or in the forest. The opportunities exist in the primary products, as well as in refining and reselling, in the value chain of energy.
The starting-point is the Farmer as an energyproducer. This master thesis studies the nature of farmer-own firms, who has invested in production of renewable energy.
Att skapa en välfungerande arbetsprocess Processutveckling på Ericsson i Katrineholm
In process oriented organizations, it is important to have well-functioning work processes tosupport the work being performed. In order to accomplish this, the organization has to makecertain decisions regarding the design and usage of the processes. This master thesis is based ona case study of a work process that is being used for the industrialization of products at Ericssonin Katrineholm. The aim of the study is twofold. One aim is to improve the studied process byidentifying improvement opportunities and carrying out the required adjustments.

Röd Glöd : Granaternas betydelse under yngre järnålder med fokus på Gamla Uppsala
During an excavation at Old Uppsala 571 raw garnets was found. In comparison with similar fragments from other sites in Sweden my aim was to prove a completely domestic production of garnets for cloisonné work. I have chosen to look at the archaeological sites of Old Uppsala, Valsta, Slöinge and Paviken and more closely at the material from Old Uppsala and Valsta. My theoretical framework has been to look at the garnets own agency in the contemporary society.Garnet cloisonné was a popular jewellery form during the Merovingian period on the continent although it came to an end in the early 7th century. It was during this time in Scandinavia a new sort of garnet, technique and paste was introduced and the garnet cloisonné was profoundly used for the gear of the elite and ritual objects.
Kartläggning och analysering av initieringsprocessen : En fallstudie utförd hos Teknikgruppen för RV2012 på Sandvik AB
This thesis has been carried out to the Technology Group at industrial plant Tube Mill2012, which belongs to the Sandvik AB. Technology Group is a unit that takes care ofall requirements and suggestions regarding investigations, test runs and designmodifications. The main objective is to identify and analyze the existing initializationprocess to see where improvement opportunities exist and to come up withsuggestions for improvement, supported by previous research and literature. Anextensive literature search and case study has been conducted to provide a solidfoundation to refer to during the work. Completing the interviews and the workshopgave a clear picture of their unstructured work and approach, how the lowrequirements on the received orders caused problems for the group as well as thelack of a standardized resource allocation method provides major delay factors.Solution proposal then became a very easy process model in five steps with all theinformation gathered in one place.
Funktionsupphandling av solelanläggningar
This thesis aims to contribute to improved functional procurement of photovoltaic systems, PV systems. Functional procurement means that criteria concerning a function are set rather than specifying technical details or products. Possible advantages and difficulties in using functional procurement have been analyzed by interviews, simulations and a case study. Electricity production and surplus production for different scenarios have been simulated via MATLAB. The MATLAB script was also used to generate rules of thumb on feasible solar fraction for six different load profiles; a church, a farm, a car mechanic, an office, an industry and an apartment building.
Locally produced pork ? Västra Götaland
The interest for locally produced food has increased the last couple of years, and some consumers have a willingness to pay a premium for niche products like locally produced food. At the same time it seems like the Swedish pig production are in a negative development period. This study tries to see if locally produced pork could be a possible factor which might affect producers in the county of Västra Götaland views on different aspects regarding their production. Consumers of pork and their point of view regarding locally produced pork were also studied. Surveys to consumers and producers were constructed.
Although previous studies claim the opposite, in the two locations (Högsäter and Uddevalla) where the consumer survey were performed, there were more men than women that always bought locally produced pork.
Local poultry production in rural Zambia and the effect of light on poultry performance
Zambia is a country in Southern Africa where poverty is widespread and the traditional keeping of local poultry therefore plays a crucial role in improving nutrition. Meat and eggs from poultry are important sources of protein but also of income. Improving the poultry production is thereby a method to fight poverty. For poultry, the access to light is an important factor for both growth and egg production. In this paper, the focus is on the traditional village chickens used for both egg and meat production, how they are kept, their health and welfare and if the use of a solar lamp will influence their behaviour, growth and egg production.
Three studies were conducted in Chibombo and Choma Districts in Zambia were 17 farmers were interviewed regarding the village chicken management of which six farmers participated in a solar lamp experiment.
En studie om Lean Production som effektivitetsteori i virkesanskaffningsprocessen : ett hjälpmedel för ökad effektivitet med kunden i fokus
Effektivitet är för många organisationer ett begrepp som förknippas med att utnyttja sina resurser maximalt. Detta är något som även är märkbart inom svenskt skogsbruk, där man idag är mycket mån om att vara resurseffektiv i sin verksamhet. Det finns dock fler innebörder av effektivitet som begrepp. Toyota, med sitt Toyota Production System, och lean production har bevisat att en flödeseffektiv process med kundfokusering kan vara ett framgångsrikt arbetssätt.
Denna studie tar upp lean production som teori i svenskt skogsbruk och knyter an denna mot virkesanskaffningsprocessen.
Styrkan i OEE som arbetsmetod
The E-department at GETRAG All Wheel Drive in Köping have problems with the efficiency on parts of their production equipment. The equipment with the most significant efficiency problems are four automated multifunctional production cells that produces housing for rear drive units. The major part of the problem is the large amount of small stops that causes the low efficiency.The department already worked with logging of interruptions and efficiency calculations before this project started. However this work was not done to the extent considered necessary for a systematic follow-up of the interruptions.The aim of this paper is to point out a more effective and systematic way to work with logging of interruptions and the follow-up. In addition the equipment were studied with a method for efficiency calculation that ? if used properly- is a more powerful and a visually better method than the one used by the company today.As the initial current state analysis of the equipment was made a lack of documented knowledge about the equipment was discovered.
The impacts on Indian farmers when converting to organic cotton production : an organisation theory perspective
Changes in the environment are affecting the world market, and pressures from several stakeholders? are forcing different enterprises to adjust to the current situation. Farmers? difficult working conditions and environmental impacts of the conventional cotton production in India have been highlighted. The small-scale production that is characterising India?s cotton farmers implies an insufficient competition power.
Accessoarer för framtidens kontor
This thesis investigates if a system for small scale electricity production located in anurban environment can be profitable. The work has been divided up into two parts,one extensive literature study and one case study. The purpose of the literature studywas to investigate the area, resulting in a choice of which technology to be studied indepth in a case study.In the case study a system containing small scale wind turbines and photovoltaicsmounted on Gränby Centrums roof was examined. From data containing wind power,wind direction and total irradiation, possible production from a system weresimulated. Three products of each technology were examined in the simulations.From the simulated production an economic analysis was carried out, this toinvestigate if a system is profitable.
The use of artificial insemination in dairy farms in urban/peri-urban Kampala, Uganda : a study of knowledge, attitude and practices
Uganda is one country with fastest growing populations in the world and with more than 25% of the population living in poverty. There is a rapid rural urban migration with increasing demands for food for low income earners especially in these areas. One way to mitigate food insecurity is to increase milk and meat production efficiency, and thus reproductive performance of cows is crucial for good production. A well-documented strategy for improving dairy cow productivity through faster genetic improvement is to breed dairy cows using proven semen via artificial insemination (AI). AI has been used in Uganda for over 60 years but only less than 10 %, a small population of the country?s herd has been bred that way.
The aims were to study knowledge, attitude and practices factors influencing cow fertility results on dairy farms around Kampala using AI and to propose ways of promoting increased use of AI in Uganda.
