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.
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.
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.
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.
Styrelsearbete över tid - En studie av företagsutvecklingens påverkan på styrelsearbetet i ett onoterat svenskt familjeföretag
In this study we have focused on how board work is affected by companies growth and development. This research has been conducted through a case study of Teleopti AB, a private Swedish family-owned company, together with theory and literature studies. We have studied the development of Teleopti since its founding in 1992 until today and what impact this company's development has had on Teleopti's board work and composition during the same period. Through the study we came to the conclusion that Teleopti's board work has gone from being supportive and advisory to more professional with a higher degree of board involvement. This change has been caused by the reduced information asymmetries, the increased need for board's expertise, the new board dynamics and the CEO change caused by the company's growth..
Värdeskapande i nätverk
The purpose of this thesis is to examine value creation in networks. Based on a case study of Livebookings Network, an online booking service. This thesis has an explorative nature. As a theoretical framework we use theories on value and network dynamics. By combining these theories we develop an operationalized framework that we use to analyze our empirical findings.
Behovsstudie av ett energibutikskoncept för energiförsörjning utanför elnät : ? En småskalig fältstudie i Namibia
The amount of electricity is limited in Namibia and the large distance between towns andvillages complicates the energy supply in the country. Therefore an alternative way to provideaccess to appropriate energy technologies is needed. The Government of the Republic ofNamibia (GRN) has adopted an approach of helping off-grid households by establishing EnergyShops in each region in Namibia and these shops are going to sell basic renewable energy andenergy efficient products. The Renewable Energy Efficiency Institute in Namibia (REEEI), theinitiator of this thesis, is coordinating the establishment of these Energy Shops.The main purpose of this thesis was to examine the needs of energy products for the Namibianpopulation and develop an assessment method for the Energy Shop in how to select appropriateenergy products already on the world market. The purpose was also to develop a method forchoosing an Energy Shop.
Klassiska populationsmodeller kontra stokastiska : En simuleringsstudie ur matematiskt och datalogiskt perspektiv
I detta tvärvetenskapliga arbete studeras från den matematiska sidan tre klassiska populationsmodeller: Malthus tillväxtmodell, Verhulsts logistiska modell och Lotka-Volterras jägarebytesmodell. De klassiska modellerna jämförs med stokastiska. De stokastiska modeller som studeras är födelsedödsprocesser och deras diffusionsapproximation. Jämförelse görs med medelvärdesbildade simuleringar.Det krävs många simuleringar för att kunna genomföra jämförelserna. Dessa simuleringar måste utföras i datormiljö och det är här den datalogiska aspekten av arbetet kommer in.
Kontanthantering i förändring : En fallstudie om samarbetet i strävan mot att minska kontanthanteringen i samhället.
This study examines a case of cooperation between banks, commerce, police and the municipality of Skövde, which in a project has the target to reduce the use of cash by 15 % in the city during 2011. The purpose of this study is to increase the understanding of the importance of cooperation in which different actors come together to reach a common goal, such as speed or interfere with an ongoing change, while they must meet their own interests. In this study the case of cooperation has been studied by using a qualitative approach. The methods used in this study are participant observation and a group interview as well as personal interviews. The theories underlying the study revolve around the concepts of collaboration between organizations with similar interests, changes in society, conflict and resistance to change..
Har musik betydelse för studieresultat
The purpose of my study is to examine if the total study results differ between music classes and regular classes. Are there higher grades in music classes? If so, what are the causes for this? I chose to make an inquiry at two schools in different town districts, with music classes. At those schools I also collected data of pupils grades, and was informed by the principals and the music teachers about the activities. The number of respondents were ninety.The inquiry showed that the grades were markedly better in music classes, and that you can see great differences in well-being, parental engagement and ambition level, compared to regular classes.
Population i isolering : en inventeringsutvärdering
Under 2005 och 2008 inventerades förekomsten av större vattensalamander(Triturus cristatus) i Gävleborgs län. Ett till synes isolerat fynd gjordes väster om Hofors.
Inventeringarna utfördes med flaskfällor och visuell observation och lokaler valdes via kartblad enligt kriterier på vattenytans areal, rörelse och distans till väg. Syftet med detta arbete var att undersöka huruvida den observerade isoleringen var faktisk eller endast ett
resultat av den använda inventeringsmetodiken. Detta arbete baserades på en radie kring en känd population där radien baserades på spridningsdistans, mognadsålder samt tid sedan den förra studien. Lokaler valdes sedan ut inom radien med krav på areal vattenyta och förekomsten av stillastående vatten varpå inventeringar utfördes med flaskfällor.
"Säg mig vad du äter och jag ska säga vem du är" : En kvantitativ studie om efterfrågan av hälsosamma livsmedel
Obesity and overweight are today classified as one of the largest epidemics in the Western world and is threaten a large part of the population. As a reaction to this a major health trend has emerged in recent decades. Every day consumers are exposed to information from the media about what is healthy or unhealthy to eat and the recommendations change frequently.There is great interest in healthy food on the Swedish food market, but still healthy foods only represents a small proportion of the total food sales. The essay examines the gap between the current and potential demand for healthy food and if it can be explained by any of the following factors: lack of information, price, taste or cognitive behavioral.To study these questions a quantitative method have been used and 213 questionnaires were collected. The intention is to draw general conclusions about the entire population.
Folkbibliotek som mötesplats för flyktingar : En undersökning av två folkbibliotek och deras potential att öka socialt kapital i samhället
This essay points at the importance of public libraries as arenas of meetings between refugees and the local population, and by this - creating social kapital in the society as a whole. The researchers Aabø, Audunson and Vårheim have created theories about low-intensive meeting places, that means ? neutral, public places where accidential meetings with different strangers can happen, which can create social capital and trust among each other. To complement these theories I also use Vårheim who have implementet social capital-theories to the sphere of public libraries. These two theories complement each other and can help me investigate two public libraries in a rural area in Sweden.
Flodpärlmusslans status i Laxtjärnbäcken : Effekter på flodpärlmusslan av sedimentbelastning och förekomst av bäckröding
The aim of this present study was to determine and evaluate whether the presence of brooktrout (Salvelinus fontinalis) and sediment load may be a threat against the reproduction anddistribution of freshwater pearl mussel (Margaritifera margaritifera) in a creek located innorthern Sweden. Freshwater pearl mussel is an endangered species and is dependent ofbrown trout (Salmo trutta) to reproduce. Therefore there are concerns of indirect effects onthe population of pearl mussel by competition between brown trout and brook trout. Ditchesfrom a nearby gravel road have been fixed to lower the sediment load into the creek. I tried toevaluate this action plan.
Grey-sided vole and bank vole abundance in old-growth forest patches of different size and connectivity
Vole populations in northern Scandinavia vary in cycles with peaks every third or fourth year as described by the National Environmental Monitoring Programme of small mammals (NEMP). Some vole species have declined in population numbers since the NEMP started in 1971, especially the grey-sided vole (Myodes rufocanus) which is nearly extinct in the forested region. Since small mammals are an important food source for several avian and mammalian predators, the decline in vole numbers is expected to have consequences for the whole food chain, especially if other vole species start to decline in numbers. This study tried to test the hypothesis that presence and abundance of M. rufocanus (a specialist species) and Myodes glareolus (a generalist species) can be predicted by patch size and connectivity of forest patches >60 years old with a minimum of 15% pine >100years old.
