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.
Tillämpning av ett medium : kvalitativ pilotstudie av två generationers användning av iPad
This study aims to investigate and describe the direction of the ideological development of the Swedish gymnastics association Gymniska Förbundet. Between 1928 and 1932, this organization transformed from a purely gymnastic and cultural association into an influential platform for the production of Swedish nationalist ideology. Based on theories of National Socialism?s formation within modern society, the analysis focus on the conditions regulating Gymniska Förbundets relation to modernity. Thus the study examines the association?s ideas in relationship to the concept of modernity.
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.

Människovana grävlingar som testdjur för grythundar. En studie om hur grävlingars beteende och fysiologi påverkas av hundars aggressivitet
In Sweden live badgers are used in tests in order to train and prepare earth dogs for hunting underneath ground. This has for several years causeddebate concerning the welfare of the badgers. It is questioned whether the purpose of the dog training, i.e. to reduce injuries in both dogs and prey, is worth the suffering that is reflected on the badgers. The aim of this investigation was to study 1) stress levels in badgers when used in earth dog training, 2) if the stress load differs when the badgers are exposed to dogs with varying aggression levels (low, moderate, high).
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.

Generationsfonder : En jämförelse mellan generationsfonderna i Sverige
In the future the Swedish pension system will face major problems. With an increasing aging population combined with a decreasing share of working population the financing of the pension system is becoming a bigger problem than previously predicted. This means the individual himself will have a bigger responsibility to invest money for their future retirement. It has been shown that a large proportion of the people who invests for their future pension have neither the interest nor the time to actively invest their pension capital. To make it easier for those who invest for their retirement, some Swedish banks have created so-called generation funds.
Björkbarksextrakt, BBE : en lönsam lösning på betningsproblematiken?
The calculations in this thesis are evaluating the profit as a consequence from treating young stands of pine in Sweden with birch bark extract, BBE. Treatment is to be done with the object to lower or fully reduce the moose browsing on pine. The study is made in three versions. The results from each version separately will follow below.
Version I.: The size of the moose population is in no way affected by the reduced resources of food as a consequence of large scale treatment with BBE on pine. Results show profit at a 3 percent level of interest with the exception of treatment program with more than 4 treatments all together and with the exception of Västerbottens Län with an early first treatment.
Version II.: The population of moose decrease from 10 to 5 individuals per 1000 ha as a consequence from large scale treatment with BBE on young pine stands.
Informal settlements : the world's invisible communities
Since the beginning of the new millennium the world?s population has increased exponentially fast. The majority of this growth has been accommodated for by urbanization of the developing world. This in turn has lead to a wide spread of informal settlements. Thus, areas of urban slums, that have risen illegally on the marginal lands within and at the periphery of the formal city.

Planera för integration : med utgångspunkt i projektet Norra Sorgenfri
Integration is a concept that is very topical in today's multicultural-cultural society. Integration means that everyone should have the same rights, opportunities and obligations to society, regardless of extraction. What counteract integration is segregation, which implies a distinction between different groups and where there exist an inequality between them. Segregation is widespread in Sweden today and the exclusion that it creates needs to be broken.
The aim of this paper is to examine if it is possible to promote integra-tion through physical planning.
Biologiundervisning utomhus : En studie av utomhusundervisningen inom biologiämnet i grundskolans senare år.
Syftet med detta arbete är att studera utomhusundervisning inom biologiämnet i grundskolans senare år. Arbetet syftar även till att fastställa Ekobussens roll i utomhusundervisningen. Frågeställningarna lyder som följande:?Vilken inställning har lärare till utomhusundervisning inom biologi??Vad finns det för fördelar och nackdelar med utomhusundervisning??Vad får elever ut av utomhusundervisning??Hur använder sig lärare av Ekobussen och vilken inställning har de till den?För att få svar på dessa frågor genomfördes en enkätundersökning med lärare och elever samt djupintervjuer av tre lärare.Resultatet i undersökningen visar att både lärare och elever anser att utomhusundervisning inom biologiämnet inte bedrivs i tillräcklig utsträckning. Orsaker till detta är bland annat osäkerhet hos lärare, brist på bra exkursionsplatser i närområdet samt att det är schematekniskt svårt att få tid att komma ut.Undersökningen visar att de stora fördelarna med utomhusundervisning inom biologi är att eleverna anser sig koppla teoretisk och praktisk kunskap samman samt att många sinnen stimuleras vilket underlättar inlärningen..
Enbarnspolitik och saknade kvinnor : en fallstudie av rätten till liv i Indien
It is not unusual that women and children fall behind in development countries. It is not even unusual that these groups are exposed to all forms of discrimination due to the countries lack of capacity to erase poverty. We also know that women and children in a larger extent suffers from the shortage of proper health conditions. India is one of these countries. It is a country where women even before birth are exposed to discriminatory family planning.
