Ett högre uppdrag : om ledarskap för studie- och yrkesorienteringen i grundskolan

Denna studie har haft som syfte att belysa ledarskapet i grundskolan avseende den studie- och yrkesorienterande verksamheten samt förhållandet mellan ledarskap, personalens engagemang och verksamhetens resultat. Avsikten har bland annat varit att synliggöra om skolorna har ett reellt ledarskap avseende verksamheten eller inte. Bedömningsgrunderna för ett reellt ledarskap har inspirerats av den transformativa ledarskapsteorin. Studien baseras på enkätsvar från 107 yrkesverksamma studie- och yrkesvägledare i Stockholms, Skånes och Västerbottens län. Resultatet visar att den stora majoriteten skolor saknar ett reellt ledarskap avseende verksamhetsområdet samtidigt som flera studie- och yrkesvägledare säger sig vilja inta en ledande funktion för detta.

Att marknadsföra politik i Sverige : En fallstudie av tre svenska politiska partiers marknadsföringsstrategi gentemot yngre väljare

BackgroundPolitics in some ways has always been about communication and marketing. In Sweden some people believe that communication and meaningful relations with the voters are of no value, instead it is the political content that is of importance. Media evolution has changed the conditions of political marketing; this has meant that the choices of the right communication channels in political marketing have become more important today than ever. Political competition in Sweden has become more even in recent years, this has called for political communication and marketing to be more planed and well thought out. Political parties have therefore begun to spend millions on marketing themselves.

Utveckling av biotopdatabas och tillämpning av landskapsekologisk analys i Huddinge kommun

På grund av ökad urbanisering och exploatering av grönområden i stadsnära miljöer fragmenteras och reduceras arters habitat vilket bland annat ligger till grund för den globalt minskade biologiska mångfalden. För att stärka och förbättra arters möjlighet till spridning i landskapet, och därmed säkra en hög biologisk mångfald, efterfrågas insamling av data och utveckling av nya metoder för att identifiera ekologiska kärnområden och för att analysera habitatnätverk. Syftet med den här studien är därför att 1) kartera och sammanställa biotoper i en biotopdatabas utifrån tolkning av infraröda flygbilder med digital stereofotogrammetri, 2) undersöka olika metoder att samla in data med hjälp av laser- och höjddata, och 3) att tillämpa landskapsekologisk analys på underlag i biotopkarteringen.Resultatet validerar att tolkning av infraröda flygbilder med digital stereofotogrammetri är en utmärkt källa för att kartera biotoper som medför en tolkningsnoggrannhet på 86 %. Valideringen av kateringen genomfördes med fältkontroller som utvärderades i felmatriser. En metod har även undersökts baserat på tidigare studier för att uppskatta busk- och krontäckning med hjälp av laserdata, men eftersom det saknas validering av resultatet bör den användas som en indikator för att visuellt uppskatta busk- och krontäckning i dagsläget.

Estimation of heterosis and performance of crossbred Swedish dairy cows

The heterosis effect and breed group effect of crossbreds between Swedish Holstein (SH) and Swedish Red (SRB) was estimated in this study. Observations on cows born between 1990 and 2012 were used to estimate the heterosis effect and breed group effect for several traits included in the Nordic breeding goals: production, fertility, udder health, calving performance, survival and other diseases. Breeding within the Holstein dairy breed has earlier been focused on increased milk production and conformation. This, combined with an intensive use of individual animals, has resulted in a radical increase of milk yield in the Holstein dairy cow population all over the world. However, this breeding strategy has resulted in increased inbreeding and several functional traits have impaired.

Samtalet på Facebook : En studie om IKEA Sveriges kommunikation i sociala medier

IntroductionIn this study, we have explained the complexities of social media, as it is still a relatively unexplored area. With the rapidly growing use of social media in recent years, companies have chosen to establish themselves in social networks to advertise themselves and communicate with their customers. In this study we analyze IKEA Sweden and their use of social media on the national market, where focus lies upon IKEA Sweden Facebook-page. The study intends to find out how the company uses social media as a marketing and communication tool and also analyzes the relations and conversations that occur on the Facebook-page. Purpose and research questionsThe purpose of the study was to gain a deeper understanding of how a large Swedish company as IKEA has chosen to use social media and how it's perceived by them. We also intended to find out how IKEA Sweden uses social media in their daily work and how the company communicates through this media channel.

Medvind eller motvind? : granskning av fem tillståndsansökningar från vindkraftprojektering i Sverige

The Swedish Government has decided that Wind power should have a higher contribution to the electricity generation in Sweden. Their goal is that, by 2015, the yearly production by Wind power should generate 10 TWh. In year of 2006, the 760 wind mills in Sweden generated only 0,936 TWh. Despite good wind conditions in a large extend of Sweden's land- and coast areas, the slow rate of new wind mills establishments will likely result in unattainable goals. The major problem for new establishments of wind mills is the extensive and complicated permission process. An expert group of environmental studies (Expertgruppen för miljöstudier) was commissioned by the Government to make a report concerning the problems with the expansion of wind power in Sweden.

Överlevnad, tillväxt och skador i planteringar av sitkagran (Picea sitchensis) efter stormen Gudrun

Sitka spruce (Picea sitchensis (Bong.) Carr) is just like Norway spruce (Picea abies) a species in thegenus picea. The natural range of Sitka spruce is a narrow strip along the west coast of North America. Itis the most coastal of all picea species, and very dependent on the mild and humid climate along thepacific coast.Sitka spruce has been grown a long time in the countries around the North Sea, particularly in GreatBritain where it currently is the most important species in British forestry. Sitka spruce has not beenplanted in Swedish forests to any large extent before the storm Gudrun in 2005. Several studies indicatethat the production of wood biomass is higher for Sitka spruce compared to Norway spruce.

Industrialisering av konsumentprodukt : Från inkommande material till färdigvarulager

This report examines the industrialization of a newly developed household machine on behalf of Technogarden Engineering Resources in Karlstad, Sweden. The report is a part of the final course in the Bachelor Program in Mechanical Engineering at Karlstad University and takes place in spring 2014.An innovator, an investor and a engineering consultant firm have through collaboration developed a new type of gruel machine. The product is in its final stage of construction and is planned to be manufactured in a production located in Sweden, autumn of 2014.To compete against today?s trend in outsourcing manufacturing to low cost countries for better profitability, the industrialization of the gruel machine must be done with a minimum amount of resources in order to become successful, which also describes the problem of this study. Using pre-study material in form of Lean production literature, visiting a successful production site and gathering data from involved engineers a specification was developed which describes what this industrialization must achieve and which requests can be accomplished.

Karaktärisering av äpplesorter : för framställning av juice och cider

The purpose of this study was to evaluate which apple cultivars are best suited for production of juice and cider. The study was limited to 41 cultivars. Common as well as uncommon apple cultivars were selected from available cultivars in the cold storage at Balsgård, Department of Horticultural Plant Breeding and Biotechnology, SLU.The practical part of the study consisted of the apples being pressed, and then the juice characteristics being assessed by appropriate criteria and methods of analysis. The analyses consisted of measurment of soluble sugars with a refractometer (Brix), titration of total acidity, determination of total phenolic content with a spectrophotometer, estimation of alcohol content by density meters and qualitative taste tests.The study did not account for different maturity of cultivars. Different apple cultivars were pressed on separate occasions, before and after Christmas 2010.

Ett gårdsbesök : ger besöket någon kunskap om mjölkproduktion?

Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.

Metodikstudie av trollingfisket i Vänern : Jämförelse av fångstrapportering mellan intervjuer och enkäter gjorda på trollingfiskare samt vädrets påverkan på ansträngning

There are five endemic populations of migratory Atlantic salmon (Salmo salar, Salmonidae) and brown trout (Salmo trutta, Salmonidae) remaining in Lake Vänern, whereof two are salmon and three are trout. There is one population of each species in Klarälven, also one of each in Gullspångsälven and there is a population of trout still remaining in Tidan River. Since the beginning of the 20th century endemic populations of salmon and trout have either vanished or declined dramatically due to the construction of hydropower in the rivers around the lake, and still today the future of the remaining populations remains uncertain. To manage salmonid fishes effectively more knowledge of their ecology throughout their different life-stages is needed. A large part of the Lake Vänern salmonoids lives are spent in the lake, where a mayor mortality factor is recreational fishing, especially angling.
