Over time, species colonize new areas naturally or through humans. The colonizers areoften few and founded populations represent only a fraction of the genetic diversityexisting in the original population. If the established population becomes isolated afterthe colonization event genetic diversity will remain low and if the population, in addition,remains small in size for an extended period this will lead to increased inbreeding andpossibly inbreeding depression. Metrioptera roeselii is a common species with awidespread distribution in continental Europe. During the last century, it has expanded tothe Scandinavian Peninsula which is separated from continental Europe by the Baltic Sea.My aim was to test the hypothesis that individuals in isolated populations in Scandinaviaincluding Denmark and the Baltic Sea islands are smaller than individuals in thecontinuous part of its distribution due to low genetic diversity and lacking incoming geneflow.

In Sweden exist a Swedish institute for children?s book which is a national information center. They have an annual "Book tasting" where they present statistics and trends from the latest publications of literature for youth and children.In their ?book tasting?? from 2010 a number of picture books had, as they say, children who descend from non-Swedish culture (Swedish institute for children?s book, 2010). The aim of this thesis is to investigate how the ethnical diversity describes in these picture books from 2010. To understand how the ethnical diversity describes in these books I had two questions which helped me in my research.

The usage of temporary work agencies services is increasing in the Swedish labour market and it has also caused some problems. There have been cases where employers have been accused to circumvent the preferential right to reinstatement by using temporary agency workers rather than rehire preference eligible employees during labour need.The purpose of this thesis is to describe, analyse and enhance the understanding of the preferential rights to reinstatement and study when hiring of temporary agency workers, during the period when there is preference eligible former employees, is permitted. The method being used in this thesis has been applied with particular attention to the directives, laws, legislative history and doctrine.The preferential rights to reinstatement in 25-27 §§ of the Employment Protection Act is a protection which states that the employer has to hire employees or former dismissed employees during increased labour needs. The purpose of this right is that an employer should not be able to terminate an employee due to redundancy and then later hire new employees. An employee is entitled to the preferential right as he/she meets the criteria of the Employment Protection Act.

The purpose of this study was to bibliometrically investigate and describe the research area called ?extrasolar planets?. The research questions were: Which authors were mostly cited within the area when the first authors (and their co-authors) were considered? Which authors were found in most co-occurrences? Did particular author collaborations emerge? To which institutions were most authors affiliated and did the size of the institution have an influence on whether an author was cited? What was the geographic distribution of authors and institutions and were there any patterns of collaboration?Did the image of dominating institutions and countries depend on the viewpoint?How applicable was Lotka?s law on the collected data? The data was collected from citation lists in documents from the database Arxiv.org. The documents were extracted by using the search term ?extrasolar planets?.

Since the turn of the millennium a sharp increase in the interest for bio energy has been observed. Important reasons for this growing interest can be due to the fact that fossil fuels are a finite resource. A net discharge of greenhouse gases occur when fossil fuels are burned. The discharge of greenhouse gases are considered to be the main reason to the greenhouse effect. Means of control to increase the use of bio energy has been introduced and, as intended, the use of bio energy has increased. As a result of the legal provisions the ability to pay for bio energy has increased, which the forest industry view as a problem.

Account receivables tie up large amounts of capital in. Various reports show that the actual time for customer to pay their invoices is getting longer. This is a problem both from a society and a business economic perspective. The purpose of the essay is to find out if Swedish companies have longer credit days than normal contractual terms of payment and if so, can the business cycle or the geographical distribution of sales have an impact and does it make a difference if the companies have an active monitoring of the actual customer credit days. To answer this, we studied 12 listed companies in four different sectors between the years 2000-2008. In the analysis, we reason about the results of the study and how the various factors may have influenced the outcome.

The disintegration of the Soviet Union was a vast experience, not solely for the former members and inhabitants of the Soviet Union, but also for the rest of the world. This thesis examines Estonia and Uzbekistan's different experience with transition. By examining three different aspects of transition I seek to explain Estonia and Uzbekistan's different outcome of transition. Estonia has since their independence been fully aware of the process that started with their independence. They have reformed both the political and economic system, the industry is privatized, institutions democratic and Estonia is today a member of the European Union.

Syftet med denna studie var att undersöka vilka upplevelser unga vuxna har beträffande den virtuella gemenskapen på Internet communities och hur det påverkar deras hälsa och lärande. Studien grundar sig på folkhälsopedagogiskt perspektiv och bygger på en kvalitativ studie. Under genomförandet av arbetet har åtta individer deltagit i individuella intervjuer. I bakgrunden belyser jag hur den teknologiska utvecklingen förändrar det sociala samspelet i samhället. Ökande kommunikation via Internet communities har bidragit till att människor kan ha större sociala nätvärk utan fysiska hinder.

Traditional financial management has lately been criticized, since it gives inadequate and unilateral information for decisions and strategy of the operation. The purpose of this essay is to investigate if a balanced scorecard is able to work together with a budget and become a stronger control system for the management. Essential theory underlies the gathering of data as well as the analysis, and the empirical investigation is based on personal interviews. The conclusions drawn from my analysis are that two parallel control systems could complement each other?s weaknesses.

The aim of this study is to examine the attitude among teachers towards working in subjectspecific groups, so called professional learning communities. The questions being asked arewhat the teachers want to acquire from working in them and how they consider them to beorganised.Previous research show that professional learning communities are means of strengtheningteachers and their teaching from criticism from outside stakeholders such as local politicians,but also parents. They are also means of developing the teaching and the individualteachers at schools.A qualitative study has been made at a Swedish secondary school and is reported in thisstudy. It was done in a hermeneutic discourse and when analysing the results four categoriesof answers appeared. It showed that the teachers working in professional learning communitieswanted to acquire a qualitative discussion regarding what should be taught and in whatway that should be assessed.

Hur kan urban odling skapa nya sociala nätverk mellan människor och få dem att mötas i staden? Litteraturstudien har till syfte att undersöka vilka studier som gjorts kring urban odling och socialt kapital, med fokus på överbryggande socialt kapital. Begrepp som community garden, community, kolonilott samt socialt kapital förklaras inledningsvis för att skapa ett ramverk till litteraturstudien. Socialt kapital kan förklaras som nätverk och sociala kopplingar mellan människor, och överbryggande socialt kapital är då sådana nätverk mellan människor från olika grupper i samhället. En historisk återblick ges kring hur socialt kapital, med fokus på överbryggande socialt kapital, har skapats både i Sverige genom kolonirörelsen och i USA genom olika stadsodlingsprogram från slutet av 1800-talet och fram till idag. Därefter refereras ett antal studier som undersökt kopplingar mellan socialt kapital och kollektiv odling, samt ett antal studier som beskriver kollektiv och urban odling kopplat till nätverk och möten, utan att använda begreppet socialt kapital.

Introduction: Public health is based on the determinants of health. They mutually influence each other. Structural factors and life conditions contribute to health inequality both within and between countries. Health inequality can be seen between different social groups, which can be the cause of differences in living conditions, health behavior and disease vulnerability. One of the consequences of this is segregation which means that certain groups live apart, where this distribution can be connected to economic resources and/or ethnicity.

Time of harvest affects nutritional value and digestibility of haylage since plants are in different developmental stages. The aim of this study was to examine the effect of plant maturity of haylage cut in June, July and August on digestibility and faecal particle size in horses.Forage and faecal samples used for the analysis of apparent dry matter digestibility (DMd) and particle size distribution in faeces were from a feed-study performed in the autumn of 2009. Twelve horses were used in the study, divided into three groups in a change-over experiment. Each group was fed haylage harvested in June, July or August during three periods. Faecal grab samples were taken from each horse and pooled so that one sample represented one horse during one period.

One of the most distinguishing features for companies today is that they must have a close collaboration and keep up a good relationship with their suppliers. This is important for the companies chance of survival and for them to compete in their markets. This essay will discuss the subject of Scania?s long-term collaboration with their suppliers. The purpose of the essay in this case study is to analyze if a long-term cooperation with a supplier is of essence upon renegotiations of continued collaboration.

The purpose of this thesis is to evaluate and update load curves for Fortum Distribution AB. Theload curve method is a tool used to forecast the strain of an electric grid. The method is based oncustomer annual energy consumption, outdoors temperature as well as customer category. Theload curve method was established by Svenska Elverksföreningen at the start of the nineties andfocus was put on standardizing annual energyconsumption, in order to make the method usableacross the nation. Present consumption patterns have changed since the original load curves wereproduced, which leads to a need to update the load curves.The work began with an update of present load curves according to recommendation taken fromanother earlier thesis.
