Is the modern pig suited for organicproduction environments?
With a starting point in the legislation for organic production set up by the Swedishcertification organization KRAV, the reasons to why these regulations are important isexplained and how pigs are affected by these rules. The study also shows how well the pigscope in the organic environment considering the origin of the genetic material; from theconventional pig population. The conclusion is that pigs do function fairly well in the organicproduction environment and the traits affecting their functionality involve: motheringabilities, strong legs, good meat quality, good sow durability and longevity, capacity to eatmuch roughage and dark skin color. There are however still many ways of improving theorganic population of pigs to make them more adjusted to the organic environment; forexample different traits brought into the breeding goals and the choice of good parent animals..
Jag får kommentarer, alltså är jag : En studie i bloggkommentarers betydelse och bloggskapande med skrivprocessen som utgångspunkt
In 2012 blogging reached an all time high in Sweden. Around 400,000 people made blog posts at least one time during this year. Blogs have publishing as a main purpose and can after publication be read by anyone with a computer, smartphone or tablet with an Internet connection. This makes the blogger open to response through comments that can be either constructive or destructive. No research has been made regarding blog comments and their effect on bloggers and their writing process.
Förväntningsgapets dynamik
Title: The dynamics of the Audit expectation gapIntroduction: The audit expectations gap is the difference that exists between what auditors and users of accounting information expects an independent auditor to do. Since the definition arose in 1974, much research has been done about the gap. What is relatively unexplored is how the gap changes over time within a country, and how it is affected by external events. This lack of knowledge has motivated this study.Problem: How has the audit expectation gap changed in Sweden, from the emergence of the definition until today? In which way have corporate scandals and legislative changes affected the gap?Purpose: The aim is to identify and create an understanding of how the audit expectation gap has changed in Sweden.
Kan man genom kartstudier förutse häckningsframgång för ängshök (Circus pygargus) i Uppland? :
Montagu´s harrier (Circus pygargus) is a diurnal, Eurasian raptor, which migrates from its northern breeding grounds to winter in sub-Saharan Africa. In Sweden, its core breeding area is centred on the island of Öland, with a stable breeding population of approximately 40 pairs. The province of Uppland is on the northern end the distribution range, where 4-8 pairs have regularly bred since the 1980s.
In Sweden, the Montagu?s harrier is classified as an endangered (EN) species. This classification is partly due to a lack of preferred nesting habitat, such as shrub-lands or dense wetlands with Claudium spp.
SIDAs Watergate : En ide?historisk undersö?kning av debatten om svenskt bistånd till det indiska befolkningsprojektet 1977?1980
In 1975 the Indian president Indira Gandhi proclaimed the emergency period which would go on until 1977. Under this time approximately 8 million men and women were sterilized in the name of family planning. Many of them did not volunteer. This was not just an Indian con- cern because the family planning program was largely funded by international aid. The Swe- dish involvement in the program was debated 1977?1980, in what has been called ?SIDA?s Watergate?.

Slutfasstyrning av robot : en jämförelse mellan LQ och MPC
Arbetet har utförts på Saab Bofors Dynamics i Karlskoga och dess syfte var att undersöka om det är möjligt att använda modellbaserad prediktionsreglering, MPC, vid slutfasstyrning av en viss typ av robot. Som referensram används linjärkvadratisk reglering, LQ, eftersom denna reglermetod har undersökts tidigare och visat sig fungera bra vid slutfasstyrning, dock för en annan typ av robot. Anledningen till att man vill undersöka om det är möjligt att använda MPC är att styrlagen enkelt tar hand om begränsningar på systemet på ett direkt och intuitivt sätt.Styrlagarnas uppgift är att styra en robot i dess slutfas då det finns krav och önskemål på roboten som bör vara uppfyllda. Till exempel finns det begränsningar på styrsignalen samt önskemål om att träff ska ske i en viss träffpunkt och även med en viss träffvinkel. För att utvärdera resultaten undersöks och jämförs de två styrlagarnas prestanda och robusthet.För att kunna utvärdera styrlagarnas egenskaper och jämföra dem implementeras de båda i en befintlig detaljerad simuleringsmiljö, som har utvecklats på Saab Bofors Dynamics i Karlskoga.De prestanda och robusthetstester som har utförts uppvisar små skillnader på de två styrlagarna och slutsatsen blir därmed att det är möjligt att använda modellbaserad prediktionsreglering vid slutfasstyrning av en viss typ av robot eftersom det sedan tidigare är känt att linjärkvadratisk reglering är en bra styrlag att använda.

attraktrivitet och regionplanering : Hur ska osby kunna ha en positiv ekonomisk tillväxt och befolkningsutveckling i region skåne?
AbstractAttractiveness may be defined by a variety of factors but you should see it in the public planning as it is to have a positive population growth and economic growth, through working with communications, service, housing, to name a few. This is done primarily through direct projects both within the municipality and through various partnerships between local and regional level. The progress we have seen in recent years has gone more towards a clear shell level, particularly a regional level where these have had a much greater freedom with clear geographical boundaries in between each other. Within these regions there are also clear regional groupings that have common interests and competing between each other. In my thesis, we have been distinguished including three levels of scale levels.
Energisystem med utnyttjande av restprodukter för gödsling av Salixodling för energiproduktion : studier av kretslopprojektet i Enköping och dess applicering på en kommun i Ryssland.
The purpose of this work is to study a circulation project in Enköping municipality, where the society?s rest products are used to make beneficial products. In Enköping the rest products from waste treatment plants and private sewers are used to fertilize and irrigate Salix plantations that later are harvested and burned at the local combined heating and power plant, ENA Energy AB, to produce electricity and heat. Possibilities to apply this kind of project ona municipality in Russia are also explored.Guryevsk municipality in Kaliningrad region was chosen since there is a need to improve energy systems and reduce emissions to water and air. This municipality strives to become environmentally friendly.
Analys av hemområdesstorlek hos mellansvenska vildsvin (Sus scrofa scrofa)
The wild boar population grows rapidly in number in Sweden, and it has been predicted that the annual number of shot wild boar will soon exceed the cull of moose. According to estimates, the Swedish population encompassed some 150 000 individuals in 2010. The mean annual harvest has increased by 30% since 1990, indicating that the wild boar is a species we must learn to manage sustainably. A successful management of the boars aims for a population in balance with agriculture and traffic, and also provides good hunting opportunities. For this to be possible, understandings of several aspects of the ecology of wild boar is needed.
The sows in this study had an average homerange of 707 hectares during summer, and 659 hectares in winter.
Hassel (Corylus avellana) som indikator på markanvändningshistorik
Hazel (Corylus avellana L.) is a common feature of meadows and pastures where it can grow in large populations and become very old. Is it possible to use the size of hazel stools for age determination and is it possible to use the size distribution of a population to provide information about how the land has been used? Hazel populations on ground where the lake-water level had been lowered, has been studied to validate an already developed growth model of hazel clones. Different hazel populations, on wooded meadows affected by mowing or grazing or overgrown meadows, were studied to evaluate the method utilizing hazel as land use indicator. The growth model was used to compare the size distributions of hazel populations with historical periods, which has been important for changes in agriculture or demography.

Another aim is to compare migration patterns in Norrköping with those of other municipalities in Sweden.Several data sets have been used, each of them extracted from population statistics carried out by Statistics Sweden (SCB).Data mining using association analysis is used for finding the migration pattern within Norrköping?s municipality and several questions are examined using descriptive statistics.
Den svenska guldgruvan - befolkningsregistren : Teknikens betydelse för utveckling av forskningsinfrastrukturen kring de svenska befolkningsregistren
In this paper we examine the possibilities to develop the population based research in Sweden by using technological advancements. The problem that exists with population based research today is that there is a contrast between conducting important research on one side and preserving the individuals? integrity on the other. To examine this problem we are studying two projects that are active in this area. The two projects are SIMSAM (Swedish Initiative for research on Microdata in the Social and Medical Sciences) and DDB (Demografiska databasen).
Vem vill bli socionom? - en studie om social snedrekrytering på Socialhögskolan i Lund
This essay aimed to give a basis for the departement of social work in Lund in its task to recruit students from underrepresented parts of the population to the departement and to the university by presenting which social groups are underrepresentated. The research also aimed to give an explanation of how the backgrounds of the student´s have influenced them and lead them to undertake studies of social work. The main questions were: - What background do the students at the departement of social work have as seen from the variables; sex, age, national background, class, parents' educational level, society of childhood and direction of upper secondary school? - How can the background of the students at the departement of social work be explaned by the theories of Pierre Bourdieu? The research was performed with a quantative method based on a questionnaire. The data received by the questionnaire were compared with data of the general students population and of the population of Sweden at large.
