Migration of a very large database with Swedish demographic data, using Microsoft SQL Server

SMC is in the process of developing a micro simulation model. The existing micro simulation model developed at Cornell University for US data, CorSim, is one of the fundamental parts for the new micro simulation at SMC. To develop the Swedish model, Swedish data on all individuals in Sweden during 11 years are also available. These data are organized in a database. This paper describes the process of rebuilding the database to a more useful structure.

I andra hand en studie av attraktiviteten hos boenden med hållbarhetsanspråk

There is an irregularity in the interregional migration in Sweden. An increasing proportion ofthe population is drawn to the metropolitan areas, which creates problems for the smallermunicipalities and towns when their population declines. At the same time, our whole societyis faced with a great challenge: we need to redirect towards a sustainable development, wherethe environmental issues are discussed and dealt with to secure that all present and futuregenerations are given equal opportunities to live a good life.The aim of this study is to, focusing mainly on the environmental dimension of thesustainability concept, examine the attractivity of housing with sustainability claims. Toanswer this, three research questions were used:? Was the migration motive to reduce their environmental impact a part of the decision tomove, among migrants who had moved to housing with sustainability claims?? If the motive was a part of the decision, how much impact did it have compared to othermigration motives?? Which factors in housing aiming at sustainability are considered important by peopleliving in housing with sustainability claims?The research questions have been answered using quantitative data, gained in the form of selfadministeredquestionnaires which were distributed in four different residential areas withsustainability claims in the county of Västra Götaland, Sweden.

Framtidens forntid : Geofysisk och geokemisk prospektering av järnåldersgården RAÄ 108, Fresta sn, Uppland

This paper deals with archaeological prospection of an Iron Age farm site in Toland, Fresta parish, Uppland County in Sweden. The purpose of the paper has been to see whether the geophysical methods applied (GPR & EM-38) could produce useful results that could motivate its use in similar surveys in the future. Geochemistry has been used for the purpose of identifying possible activity areas on the site. The results have shown that it is possible with a GPR survey to identify postholes originating from the Migration Period longhouse at the site. The combining of several methods have been important for the identification and interpretation of several areas of interest..

Unga svenskars temporära migration till Oslo : En intervjustudie av sex unga vuxnas beslut att flytta till Oslo och tillbaka

I denna studie undersöks unga svenskars erfarenheter av temporär migration till Oslo, Norge. Syftet med studien var att öka förståelsen för ungas temporära arbetsmigration; både beslutsprocessen inför emigrationen, och vad som påverkar vistelsens varaktighet. Detta har undersökts genom djupintervjuer med sex respondenter som alla har gemensamt att de är från Västerbotten, har bott i Oslo, och sedan flyttat tillbaka till Sverige. Intervjuerna analyserades därefter med hjälp av en kvalitativ innehållsanalys.Resultatet visar att en av de viktigaste aspekterna i beslutsprocessen var respondenternas önskan om att tjäna pengar för att kunna resa. Migration kan därmed ses som ett medel för att förverkliga sina resedrömmar.

Beteende hos lekvandrande lax i Klarälven ? utvärdering av en fiskfälla

During the migration season in 2013 a study on spawning migrating salmon and the effect of water flow on the behavior was conducted of the salmon at the Forshaga hydropower station in the River Klarälven. The River Klarälven with its nine hydropower plants on the Swedish side, constituting migration obstacles for the migrating salmon. Fortum Generation AB has together with the County Administrative Board restored a salmon trap at the lowermost hydropower station in Forshaga, aiming at making it possible for the salmon to swim into the trap, and thereafter be transported by truck past the power plants and then continue their journey to the spawning grounds on their own. Unfortunately, it is believed that the trap does not work as well as it should. In this study, I focused on salmon position in relation to water flow and if the number of salmon that swam into the fish trap differed between salmon with previous experience of the trap (experienced) and salmon without experience (unexperienced).

The role of FGFs in the elicitation of different cellular responses

Fibroblast growth factors are signaling peptides that controls important cellular processes such as proliferation, differentiation, migration, adhesion and survival. Through binding to different types of receptors on the cell surface, these peptides can have different effect on the target cell. Which effect that is achieved depends on many factors. Thus, each of the 24 known FGFs different biological responses. The FGF receptors (FGFR 1-4) initiates different intracellular pathways which in turn leads to different biological responses.

Barnets talan - en studie om beaktandet av barnperspektiv i den svenska Migrationsdomstolen : / The voice of a child - a study regarding a child perspective in the Migration Court of Law in Sweden

The following essay examines the conditions of whether a child perspective is recognised in the second authority of the new Swedish asylum process, the Migration Court of Law and inquire into the viewpoint of these decision makers as to what a child perspective in this context represents.The method used was a qualitative study that contained interviews with eight respondents, divided into four judges and four jurors. The material gained from the respondents was then analysed by using theories regarding a child perspective and theories that deal with interpretation of a text, ethics and court sociology.A few conditions of whether a child perspective is recognised has been revealed and we also found that the child perspective in theory is a wide perspective, that includes many aspects of how a child is recognised. In practice, however, the child perspective can be divided into two separate perspectives where one of them involves an adults view of a child?s perspective, and the other involves the perspective of a child, the child?s own view of its existence and perceived reality..

Från diskurs till praktik? En studie om säkerhetiseringen av irreguljär migration och dess konsekvenser

This thesis discusses the theory of securitization in relation to the issue of irregularmigration, from EU level to national level. By using discourse analysis, the purpose isto explore whether the discourse leads to practice when it comes to nationalimplementation of EU debates on return policy. The material used in this workconsists of policy documents regarding the Return Directive from the EuropeanCommission as well as the Reva Project in Swedish migration policy. The mainobjective of the Reva Project is to make the process of returning irregular immigrantsmore effective and it has been strongly criticized, both by media and public opinion.The conclusion of this case study is that even if the security rhetoric may appearstronger on the EU level, the main elements of the security discourse are stillportrayed in the implementation on the national level. Based on this analysis we canmake the presumption that discourse develops into practice in the case of returnpolicy in the EU-member state relation..

Passage efficiency and migration behavior for adult Atlantic salmon at a Half-Ice Harbor fish ladder

Due to exploitation of the world?s rivers, the upstream migration of anadromous species is frequently delayed or even prevented. To mitigate these problems and allow fish to migrate past obstacles, structures such as fish ladders have been developed. However, recent studies show that many of the present fish passage facilities are deficient. Monitoring and evaluation of passage facilities is therefore crucial to enable necessary adjustments.

Migration losses of Atlantic salmon (Salmo salar L.) smolts at a hydropower station area in River Åbyälven, Northern Sweden : passage fates at a reservoir, a power house and a bypass structure

A large number of rivers in northern Sweden have hydropower developments that cause negative effects on both up- and downstream migrations of anadromous species like Atlantic salmon. So far, most attention has focused on the hindrances of adult fish during their upstream spawning migration. However, since turbines in power stations cause losses on downstream passing fish, the focus on negative effects on smolts has increased. The aim of this study was to compare three different causes of losses of salmon smolts passing downstream through a power station area in the flow-controlled River Åbyälven in northern Sweden.A total of 61 wild salmon smolts were caught and radio-tagged in the River Åbyälven during their downstream migration in June 2009. The salmon smolts were released at three locations, 1.1 km upstream from the power station, in the turbine intake and in the upper part of a fishway, acting both for up- and downstream fish passage.

Hur påverkar ålder och fetthalt laxsmoltens utvandring till havet?

AbstractPrevious studies have shown that wild smolt have 2.5-4.5 times higher survival rate than smolt grown in culture and that starved reared smolt behave more like wild born smolt. The purpose of this project was to study whether there are differences in migration patterns and survival during migration to the coast between wild and reared smolt and between different types of reared smolt.In 2009, 25 smolts in three different groups were tagged with acoustic transmitters: Wild Born, conventionally reared 2-year and 1 ?year old smolt. For the 2010 trial there was also added a group of reared 2 ?year old smolt that were starved before release.

Migrationspolitik och xenofobi : En studie av emigranters och flyktingars rättigheter i Grekland

AbstractThe purpose of this study is to examine how Greece?s migration system functions and how immigration and asylum policies manifest themselves during the countries current severe economic crisis. More precisely, examining how the regulatory framework and policies regarding refugees' and migrant situation effects practical implementation. The research questions raised are; - How are refugees and other migrants' rights in Greece respected, from a legal, political and moral perspective? What impact can racism have on the treatment of refugees and other migrants? A contextual analysis of ideas through an analysis of the political programs/agendas was used and contrasted, through theories concerning racism, nationalism and globalization to further nuance the situation concerning refugees' rights.

Strategi, syften och visioner för intranät : av intranät i samband med uppgradering.

Intranets can streamline workflow processes, improve communication and add value to the employees of an organization. Companies that don?t take advantage of the potential in their intranet is a common phenomenon. In connection with a migration project dealing with a switch of content management system it turned out that SAS Technical Services lacked clear objectives and strategies for the use of their intranet. Thereby they didn?t make the most of the possibilities an intranet brings.The work with this thesis began with collecting the experiences the company could take with them from the migration project.

Helicobacter spp. i digestionskanalen hos svenska katter : en metodologisk och klinisk studie

Following the accident at the nuclear power plant in Chernobyl in 1986, great volumes of137Cs were distributed over large parts of the former Soviet Union and Europe. Over Scotland,radiocaesium was deposited as wet deposition. Due to the relatively long physical half-life of30 years, there are still measurable activity concentrations in the natural environment. Thisstudy was made on two organic soils, Knockandy Hill and Rora Moss, situated in the easternpart of the central highlands of Scotland. At these two sites, studies on migration and transferbetween soil and plants were conducted.
