Överlevnadsanalys och avyttringsorsaker - för ackordhäststiftelsens hästar 1967-2012

Few scientific studies have studied the subject of longevity among horses over a longer period of time. The knowledge about the Swedish riding school horse population concerning injuries and diseases is insufficient. Generally speaking, riding school horses in Sweden have a more undiversified way to work and work more hours in the arena compared to privately owned horses that have more variety in their possible use. Statistical data from the insurance company Agria have shown that horses in riding schools and education facilities have 22 % higher risk to use their veterinary insurance and 79 % higher risk to be put down and use their life insurance, compared to horses in private care. To create an increased understanding for longevity is it important to have knowledge about the different causes of culling. The aim with this study is to increase the knowledge and enable problem solving within the subject of longevity, median length of life and causes of death.

Synchronizing migration with birth: an exploration of migratory tactics in female moose

Migration and giving birth are crucial decisions for animals during their life cycle, which may have lasting consequences on their population demography and fitness. Migration can entail a variety of possible effects for an individual, such as access to high quality food and reduced risk for predation. The moose (Alces alces) in northern Sweden is partially migratory and moose females are known to give birth to one or two calves. The synchrony between time of calving and timing of migration has not been compared before, especially in terms of energy maximizing and time minimizing perspectives, which may provide vital cues for fitness benefits of migration. I investigated effect of timing of birth and individual life history on distance, timing, stopovers and duration of 190 individually marked female moose that have been tracked for multiple years in ten different areas in northern Sweden.

Price adjustment and vacancies on theStockholm market ? Estimation of rent levelsdue to office-allocations

The Stockholm office market segment have for a long time been considered a safe havenwhen it comes to withstand negative turmoil in the form of rental compression due toeconomic fluctuation, especially in the CBD demographic. Recently however, a large numberof banks and institutions, amounting to some 200000 square meters, have decided to relocateto more peripheral locations with the aim of cost reductions on rent. This mass exodus isstudied with focus on rental dynamics as the result of increased vacancies. Other variables arestock changes and employment. The method is econometric combined with an interviewseries.

Demokratiteoretisk analys av läromedel i Samhällskunskap : En kvalitativ studie om det demokratiteoretiska innehållet i läromedel för Samhällskunskap 1a1 och 1b under GY-2011

This qualitative study is done with the purpose of creating understanding for the theoretical democratic content in educational materials for Civic Education courses 1a1 and 1b during GY-11, so teachers create an intentional approach when using educational materials in their democratic education. This was motivated as important considering the reduction in obligatory Civic Education for the vocational programs. The study was conducted using a hermeneutic qualitative reading method where the educational materials, more specifically two series with one book for each course, was read with purpose of creating understanding for the democratic content according to ideal democratic models: deliberative democracy, participatory democracy and electoral democracy. A text voice analysis was also conducted using Bakhtins theory of dialogic and monologue text that contributed to the general result concerning the democratic content. The results show that the electoral democracy ideal is dominant in all educational materials, there is hence no striking difference between the democratic content in 1a1 and 1b educational materials.

Organiserade samverkansnätverk: en kartläggning av en population i Sverige och en studie av styrgruppssammansättningens påverkan på framgång

Genom att samarbeta med andra aktörer på marknaden kan företagen gemensamt bli mer effektiva och konkurrenskraftiga i syfte att tillsammans uppfylla kundernas mer komplexa och specifika önskemål genom att erbjuda helhetslösningar. Detta ligger till grund för den växande nätverksbildning som många företag insett betydelsen av. Organiserade samverkansnätverk är en typ av företagsnätverk som består av ett antal små eller medelstora medlemsföretag. Medlemsföretagen verkar på en begränsad geografisk yta och målet med nätverket är att uppnå specifika affärsresultat. Syftet med denna uppsats var att identifiera en population av organiserade samverkansnätverk i Sverige samt undersöka hur styrgruppens sammansättning kan påverka nätverkets framgång.

Hur hushållas det med mark och vatten? en studie av tillämpningen av hushållningsbestämmelserna i 3 och 4 kap MB

The national spatial planning guidelines and the subsequent legal regulation in the Natural Resources Act and the Environmental Code has been a part of the Swedish planning system for almost 40 years. In the recent years, critics have claimed that the regulations are outdated and does not work the way it was intended. This paper examines closer why it is perceived that the regulations does not work, with a focus on how the national interests are managed in the municipal planning. Why is the national interests not applied in the municipal planning as intended? Is the error in the system or in the implementation of it? The aim of this essay is to study the gap between theory and practice by studying how the land management provisions in the Environmental Code is applied in five selected municipalities. The aim is also to find interesting issues for futher studies of the topic.

Kunskapsläge och attityder till vildsvin (Sus scrofa) och dess förvaltning i Sverige

The wild boar (Sus scrofa) is since its recent establishment and increasing density a controversial species in Sweden. But the attitudes towards the wild boar are poorly documented so far. To improve this knowledge, a questionnaire was sent out to chosen people (n=400) connected to the management and/or land use activities. The study got 162 replies (reply frequency 40,5%) and the results show varying attitude trends among organizations and individuals, with some aspects coherent within groups and some not. Farmers and their organization showed the most negative attitudes towards wild boars, which was expected due to the practical and economic problems they suffer from this species. People involved with forestry were more positive to wild boars, probably because the species does not affect forest growth etc severely, and may even promote plant establishment by the rooting.

Flödeslogistik vid Laponia Hotel

The aim of this report is to analyse the logistics of a medium sized restaurant and give an overall solution for improvements on the restaurant's logistics. The restaurant of interest belongs to Laponia Hotel and is located in Arvidsjaur, Sweden. Investments for over 100.000 Euros are planned for the hotel, which includes a reconstruction of the restaurant. The details on how the restaurant will be reconstructed are not yet known. I therefore chose to analyse the problemin general terms and find a solution that is focused on the logistic system itself rather than its layout.

Den Sociala Identitetens Inverkan På Subjektiva Bedömningar Av Att Dela Värderingar Med "Andra" - En psykologisk analys av motstridiga uppgifter i Integrationsbarometern 2004

This study examined some contradictive results in a report from the Swedish board of Integration. The contradiction was concerning the Swedish populations dismissive judgments of experience a shared ground of values between the Swedish society and those witch are generally held within Islam. These dismissive judgments were given at the same time as the population reported to have a lacking knowledge of Islam in general. To test for psychological aspects of these contradictions, the analysis was based on the theoretical ground of Social Identity Theory and Theory of Attributions. The study used an existing survey that examines people´s estimations of their own and other members of society´s fulfilling of democratic values.

Konceptstudie av drivmodul till bandskotare med hybriddrift

BAE Systems Hägglunds has a long history of producing high performance terrain tracked vehicles (mostly for military applications), and they are now aiming at developing a tracked forwarder with similar techniques.The forwarder will be of series hybrid type where a diesel engine via a generator will power the motors (one for each drive wheel). Thanks to individually controlled motors and the gentle rubber tracks, this forwarder is calculated to have a considerably higher average speed in the terrain and to be more gentle to the soil. The forwarder with a weight of 11 metric tons and a load capacity of 15 metric tons is specified to have an average working speed of 7-10 km/h, a top speed in terrain of 15 km/h and a top speed on roads of 40 km/h.This master?s thesis aims at developing a conceptual design of the forwarder?s drive module which includes electric motor, gear unit, brake and drive wheel.To investigate if the requirements can be fulfilled a study of the dimensioning loading scenarios has been carried out. The resulting needs regarding the torque has been considered in order to determine the required gear ratios for different motor options.

Centralitet och periferi i det nya Europa : Städer som regionala nav i samarbete och konkurrens

European cities of today are under the challenge to find ways to stay competitive and flourish in a rapidly changing world, where the old patterns of centrality and periphery not necessarily holds true. New and improved communication networks, a changed political geography in Europe, and the globalisation of not only the financial and industrial markets but also to a certain extent the globalisation of people, have all led to great challenges for cities and regions.In a changed spatial reality the classic monocentric models are challenged by newer models of urbanisation. The polycentric urban region is one such model which has been used to describe urban regions like the Randstad in the Netherlands and the Rhein-Ruhr region in Germany. Regions which lack the single dominant central city of the monocentric models of old, and instead shows a high degree of more equal-sized and sometimes more specialised cities in regional cooperation. The polycentric urban region is in that aspect a possible model for how other urbanised regions in Europe may act to be able to position themselves as attractive urban regions and regional hubs in the European urban network.Polycentric urban regions are not a universal solution, though.

The purpose of this bachelor?s thesis is to examine how public librarians and people engaged in sports associations think of the possibility of collaboration between their organizations regarding children and youth and furthermore how they think this collaboration and collaboration in general would or should be practiced. This is done in the light of the increasing necessity of collaboration in today?s information society as well as the view that reading and sports could make a good match. Focus is placed on the libraries? perspective and also on the respondents? perceptions and thoughts.

Analys av kvalitet i en webbpanel : Studie av webbpanelsmedlemmarna och deras svarsmönster

During 2012, the employer of this essay carried out a telephone survey with 18000 participants and a web panel survey with 708 participants. Those who partook in the telephone survey were given a choice to join the web panel. The purpose of this work is to study the participants of the telephone survey and see if they reflect the Swedish population with regards to several socio-demographic factors. Also, we intend to investigate if the propensity to join the web panel differs for participants of the telephone survey with regards to various socio-demographic affiliations. It is also of interest to study if the response pattern is different for participants of the telephone survey that would like to join the web panel and those who reject.

Frekvensreglering i det nordiska kraftsystemet

Svenska Kraftnät is (together with the other transmission system operators of the Nordic power system) responsible for keeping balance between the generated and demanded power in the Nordic power system. Spontaneous load variations and system disturbances, however, lead to power imbalance followed by frequency variations. The frequency deviations can be limited to an acceptable level by the spinning reserve, mainly by hydro power control. But there are also other system properties which have a great influence on the frequency and system stability. The frequency and voltage dependence of the loads have a direct influence on the power balance.
