Integrationen av etniska minoriteter i de tre Baltiska staterna

This essay is a comparative empirical study of ethnic integration mainly of the Russian-speaking minorities in the three Baltic states (Estonia, Latvia and Lithuania) in a post-communism setting. As Lithuania has a Polish minority that is as large as the Russian-speaking, they too shall be included in the study but not as thoroughly as the Russian-speaking minority. Thus the problem is: to what degree are the ethnic minorities integrated with the titular nations in Estonia, Latvia and Lithuania? In order to study ethnic integration I have set up a theoretical framework largely based on Weiner?s theory of integration. The theoretical framework focuses on three dimensions: Citizenship, Identity and Segregation.

Den svenska lapphunden - en ras i behov av förändring?

Many pedigree dogs are suffering from inherited diseases or personality disorders caused by selective breeding. The Swedish lapphund is a breed that has been suffering from some loss of genetic variation due to the heavy use of only a few males. Concerns have arisen and crossbreeding has been discussed as a way to manage gene loss. Four breeds has been taken into consideration for this purpose; schipperke, finish lapphund, Norwegian buhund and Norwegian elkhound, black. These breeds has been tested theoretical by a comparison of mentality and health.

Upplevelser av att arbeta med djur på daglig verksamhet : En kvalitativ intervjustudie bland personer med funktionsnedsättning

The central part in all public health work is health promotion and disease preventing actions among the population. Since all public health work includes the whole population, the work has to embrace disabled people as well. Within the disability policies, participation and equality are important goals, which illustrate the importance of a job. In previous studies the positive effects of animal have been detected among persons with disabilities, by better balance, better mobility, larger social network, new knowledge and most of all happiness. The aim of this study was to investigate how people with disabilities experience their health when they are working with animal husbandry at daily activities.

Reformation of the credit rating industry - Is there a need?

The credit rating industry is a complex and fascinating industry. Its history stretches back more than 150 years and has gradually increased in importance. During its history the dynamics of the industry have changed. The extended-principal-agent model was developed by synthesizing different principal-agent-relationships into one model. This model provides a holistic understanding of the credit rating industry and illustrates the interdependence between the different relationships.

Hultsfredsfestivalen : Hur ett evenemang kan inspirera, påverka och utveckla en ort.

Purpose: The purpose with this study is to clarify what importance a co-occurrence event can have on a smaller town, and also what positive and negative consequences it can have on the town seen from a social, economic and political aspect. I will also look at what magnitude the festival have on the local commercial and industrial life and how it affects those who live there. I will also determent how the moving of the festival might come and affect the local businesses, the local population and the community it-self.Method: I will thorough-out this study work with qualitative research methodology. I will there-for process the empirical data that will be collected and used for this study from a qualitative research methodology point of view.

Att möta den som ropar högst : En studie om biståndshandläggares bemötande av demenssjuka individer

The Swedish population is getting older and more elderly will continue to be in need ofsupport from the community to meet their everyday lives. As the population gets olderdementia also increases the spread in the country. Because of this more people withdementia will be in need of help in their everyday lives. This will increase the demandson elderly care in the municipalities where they have to offer good care. As moreindividuals suffering from dementia will be in need of help in their daily lives aid officers'encounters with people suffering from dementia and their relatives or any representativesbecome more common.The study had as objective to study aid officer's reasoning on the treatment of dementedindividuals in need of help.

Fiskarebönder och landskapet i Karlshamns skärgård förr och nu

Hällaryd archipelago, consisiting of approx. 50 islands, islets and skerries, is situated east of Karlshamn city in Blekinge province. The archipelago has been shaped into a rift valley by volcanic activity, the inland ice and maritime climate.The archipelago is divided into seven main islands: Bockö, Västra Bokö, Ekö, Hallö, Joggesö, Mjöö and Tärnö. This essay will connect population changes with land use.

Genflödet från genetiskt modifierade grödor till vilda populationer

Tillämpningen av genetiskt modifierade (GM) grödor har varit utbredd över hela världen och har ökat markant sedan den första GM-grödan blev tillgänglig för kommersiellt bruk 1996. Sedan starten har det tillkommit mycket forskning kring risken för spridning av transgener från grödor till vilda populationer. För att en transgen ska kunna etableras i en vild population så måste tidiga generationer av hybrider överleva för att kunna återkorsas upprepade gånger med den vilda arten, det gör att det genetiska materialet från grödan succesivt reduceras i varje generation tills det att transgenen är det enda DNA från grödan kvar hos avkomman. För att denna process ska vara stabil krävs det en stark selektion för transgenen. Det här sättet för en gen att etableras i en population kallas för introgression och tros ha spelat en stor roll i växternas evolution.

Batterilös strömförsörjning av strömsnål granatelektronik

Detta examensarbete har utförts vid Saab Dynamics AB(SBD) i Karlskoga med syftet att studera gamla konstruktioner av set-back-generatorer. En set-back-generator (SBG) ska ge momentan energi vid utskjutning av en projektil genom att en magnet rör sig genom en spole. SBG har funnits länge men har bedömts ge för lite energi för att kunna driva elektronik. Men nya typer av magneter har potential att öka energiutbytet väsentligt.SBD har ett antal äldre SBG:er och arbetet har varit att utifrån dessa undersöka om det går att utvinna mer energi genom ett utbyte av magnet. Andra parametrar som är viktiga för en SBG:s funktion har också studerats och testats i olika konfigurationer i hopp om ytterligare förbättringar.

Demokratins förutsättningar i Västafrika : En jämförande studie av Ghana och Guinea

In subsequent to Post-colonialism the African nations have dilated into different political directions. While some nations have established well-functioning democracies, others are still under authoritarian regimes. The aim of this thesis is to examine if civil society has an impact on democratic development in West Africa. Therefore the theoretical starting point is Putnam?s theory of social capital, but this study will also examine other possible causal explanations for democratic transition.This study will be based on a comparative analysis of Ghana and Guinea.

Fyraåringars kostvanor och fysiska aktivitet

Övervikt och fetma bland barn är ett snabbt växande hälsoproblem i västvärlden, problemet är bland annat minskad fysisk aktivitet och kost med ett stort fett- och sockerinnehåll Den som varit överviktig som barn kan i större utsträckning få hälsoproblem i vuxen ålder Eftersom detta grundläggs redan i barndomen har distriktssköterskan på barnavårdscentralen en viktig roll att fylla. För att distriktssköterskan skall kunna hjälpa och stötta familjen bör de veta hur fyråringar äter och hur de rör sig. De Svenska näringsrekommendationerna kan vara stöd i samtal med föräldrar. Syftet var att kartlägga fyraåringars kostvanor och fysiska aktivitet och undersöka samband i en regional population i Mellansverige. Kostvanorna hos den regionala populationen av fyraåringar jämfördes med kostvanor hos en nationell population fyraåringar.

En indirekt metod för adaptiv reglering av en helikopter

When a helicopter is flying, the dynamics vary depending on, for example, speed and position. Hence, a time-invariant linear model cannot describe its properties under all flight conditions. It is therefore desirable to update the linear helicopter model continuously during the flight. In this thesis, two different recursive estimation methods are presented, LMS (Least Mean Square) and adaptation with a Kalman filter. The main purpose of the system estimation is to get a model which can be used for feedback control.

Sensory studies of an energy dense drink for elderly people

The average length of life is increasing in the western world, hence the older population is growing. A common health problem among the elderly is malnutrition. Malnutrition causes decreased body strength and is associated with an amplified risk of infections, depression, fractures and increased mortality. The health care system is therefore faced with the challenge to prevent malnutrition among the growing population of elderly. This could be done by providing nutritious foods developed to meet the specific needs of elderly. The overall objective of this project was to test a healthy energy dense drink based on oats targeted for the elderly consumers as a strategy to prevent malnutrition among elderly.

A risk analysis of moose close to roads

For many decades the increase in traffic volume, expansion of highways and infrastructure has lead to an increase of wildlife vehicle collisions which are unfortunately very common in many countries today. They cause great deal of material damage and even kill humans or wildlife. Measures in the form of warning signs, under- and overpasses and fencing have been implemented for a long time with the help of observation by hunters and collisions sites. However this study focuses on the moose?s perspective and the variables that, both spatially and temporally, could have an effect on why and when moose are close to certain types of roads.

Tid är dyrbart och det gäller att göra det bästa möjliga av det man har : Utvärdering av en ledningsgrupp baserad på intervjuer, enkätundersökning och observationer.

The purpose of this study was to identify the positive and negative aspects of the work and dynamics of a management team and from that recommend how the team can improve. The aim was also to investigate whether there was a gap between how the members of the management team comprehend themselves and how the project, section and team managers comprehend the management team. The management team contains of seven core team members and is the head function of a research and development site in central Sweden. The results are based on interviews with the present members of the management team and three former members, a survey among the project, section and team managers and by participating observation on meetings with the team. The results show that the management team is an overall well-functioning team that with some changes and improvements, especially concerning communication and information, can reach even further.
