Kaliumgödsling på torvmark - effekt på tillväxten hos planterade granar (Picea abies)
Peat lands are a great potential resource for increased forest growth in Sweden, there are approximately 6.5 million hectares of peat lands, whereof around 70% produce less wood than one m3sk/ha and year and are therefore classed as forest waste land. There are over 200 000 hectares of peat land that is already drained and wooded, and that may be suitable for fertilization. Forest production on peat soils usually requires drainage and fertilization. Dewatering requires ditching the area, so that the roots can have access to oxygen. Nitrogen is often abundant in the peat but other nutrients; especially potassium is in short supply. The purpose of this work was to examine the effects of potassium fertilization on the growth of spruces that were planted on drained peat land and how different amount of fertilizers affects the growth. Potassium deficiency is strongly growth inhibiting, since potassium is important for substance transport in the tree. Potassium is also important for the carbohydrate formation, and because increasing the sugar content of the cells constitutes a lower freezing temperature does potassium availability in the soil play a major role in the winter resistance of many species. Potassium is not found in any organic compounds in the tree, but is present in cell and tissue fluids. A fertilization trial was started in 1978 in Siljansfors Experimental Forest. The plots in the experiment were fertilized with different amounts of potassium and one plot was left without fertilization. All plots that were fertilized with potassium grew considerably better than the unfertilized plot. The difference in production between the unfertilized plot and the plot that received the most potassium was 7.2 m3sk/ha and year. The unfertilized plot can still be classified as waste land. The theoretical production capacity was estimated using a Swedish system for site quality estimation of wetlands after ditching (dikningsbonitering). The plot with most potassium produced after fertilizationaproximately in level with theoretical estimations. Key words: Peat land, Fertilization, Ditching, Growth, site quality..
Inventory and evaluation of Nairobi Animal Orphanage : focusing on spotted hyena, serval, Sykes' monkey, vervet monkey and on educational elements
The present BSc thesis is part of a newly established collaboration between the Swedish zoo Skansen and Kenya Wildlife Service (KWS), and constitutes of an inventory of the Nairobi Animal Orphanage (AO). As a refuge for wild animals found orphaned, abandoned or injured throughout Kenya, the AO has grown over the years and reached an unsustainable point where external help is needed for solutions and improvements. The aim of the inventory is to specifically consider the husbandry and enclosures of spotted hyena (Crocuta crocuta), serval (Felis serval), Sykes? monkey (Cercopithecus albogularis) and vervet monkey (Chlorocebus aethiops) and with the aid of facts about the species, estimate how well their biological needs are satisfied. Different educational elements are also reviewed since one of the main purposes of the AO is for education.
Gullrisbock (Phytoecia nigricornis) i grus- och sandtäkter i Halland.
This dissertation is done as a preparatory step for the action plan of environmental protection shall issue to preserve the Phytoecia nigricornis in the country when it is red-listed and classified as vulnerable (VU). My task was to investigate the prevalence of the Phytoecia nigricornis in Halland County. They wanted to see if it existed in Halland (Ehnström, 1999). If it did not exist they wanted to know how to improve its habitat.the Phytoecia nigricornis is difficult to inventory because when it is larvae it lives in the roots and lower parts of the trunk of the Solidago Virgaurea plant and the adult beetles only keeps to Solidago Virgaurea by mating and egg laying and larval caterpillars when they hatch (Bily, 1989; Molander, 1999). Often it is overlooked or missed, and one question was whether it existed in the whole country or only in those parts where it was previously found in, Skåne, Blekinge and Östergötland (Ehnström, 1999).One problem for the Phytoecia nigricornis is that their habitats is declining.
Etnisk diskriminering i rekryteringssituationer : Hur skyddet ser ut i Sverige och vad arbetsgivare kan göra för att förhindra diskriminerande rekryteringar
Ethnic discrimination is still a problem in the Swedish employment market. The Ombudsman against Ethnic Discrimination received 154 complaints relating to discrimination due to ethnicity in the working life in 2012. In addition, reported unemployment rates in Sweden differ markedly between native-born and foreign-born. The purpose of this paper is to investigate how protection against ethnic discrimination in recruitment looks like in Sweden and describe different methods an employer may use to prevent that ethnic discrimination occurs in recruitment situations. The first and second issue of the essay concern what protection there is in Sweden against ethnic discrimination in recruitment situations, based on international and national law. The traditional legal dogmatic method, which describes the valid law, is used in these sections.

Kaninhållning för sällskapsbruk
The domesticated rabbit stems from the European Wild rabbit and researchers have found that they share most of the characteristics and behaviors of their wild ancestor. They form mating groups in which strong hierarchic orders are formed and they are known for their ability to dig warrens which serve as one of the most important resources for this species. Although research has been performed to increase the welfare of rabbits kept in laboratory settings little is known about the housing, behavior and welfare of the pet rabbit. Among the research that has been performed within the area results have shown that the animals are kept in small solitary cages and that although many rabbits are purchased mainly for the children many animals cannot be handled by children due to display of aggression. Another conclusion drawn is that the animals are kept in ways that differs greatly from their natural environment.
Kompetensutveckling av personer i ledande befattningar : En studie om mentorskapets inverkan på ledarskapet
Title: Leadership development of individuals in management positions Authors: Carl Renér and Peter Simonsson Institution: Linneaus University, School of Business and Economics Program: Human Resource Management Course: Business administration ? Organization including thesis, 15 credits Supervisor: Olle Duhlin (Linneaus University, School of Business and Economics) Examiner: Mikael Lundgren (Linneaus University, School of Business and Economics) It is widely known that the role of managers may result in stress and a heavy workload. As a result of this negative effects organisations have to counteract and find new solutions and systems to facilitate and assist leaders in their work. A popular method for leadership development has come to show both in research and in practice, especially in recent years, this popular method is known as mentoring. This form of leadership development is often applied in so called mentoring programs.
Är kolrika jordar en källa till fosforläckage? : en sammanställning av data från 130 åkerjordar
Phosphorus (P) is an essential nutrient but a surplus could lead to eutrophication. Furthermore,
the minerals used to produce the mineral phosphate is a non renewable resource.
There are in other words several reasons to reduce the leakage of P and the agriculture is one important area to attend. The aim of this work has been to investigate if carbon-rich arable soils content contain more P than arable soils with low carbon content. Moreover it has been calculated if the carbon-rich soils could pose a risk of P leakage by comparing their delivery of P with the plant uptake. The work has consisted of compiling the results from former gathered and analysed soil samples of 130 Swedish arable soils.
The fractions of P considered are water soluble P (Pw), ammonium lactate-extractable P (P-AL), hydrochloric acid-soluble P (P-HCl), organic ammonium lactate-extractable P (Porg-AL) and inorganic ammonium lactate-extractable P (Porg-HCl).

Subjektivitet är en naturlig del som rekryteraren måste hantera. Det får inte influera omdömet till den grad att kravprofilen inte följs.
Att lyckas med utstationering - En kvalitativ studie kring framgångsfaktorer och svenska expatriater
Denna studies syfte var att undersöka svenska expatriaters erfarenheter kring fram-gångsfaktorer som leder till att lyckas med utstationeringen. Studien fokuserade på framgångsfaktorerna expatriatens personlighet och organisationens agerande.Studien har utgått från Briscoe, Schuler & Claus (2009) definition att en lyckad expat- riat ska ha fullföljt uppdraget, haft en bra kulturell anpassning samt varit effektiv på ar- betet. Vidare är studiens teori uppdelad i två delar; expatriatens personlighet och organi- sationens agerande. Expatriatens personlighet undersöktes genom Big Five, eller fem- faktormodellen över personlighet. Organisationens agerande har baserats på tidigare forskning samt litteratur vilka har belyst rekryteringsprocessen, innan, under och efter uppdraget.Kvalitativa intervjuer valdes som metod för studien.
Analys av system för rening av avloppsvatten i en anaerob membranbioreaktor
The most common way to treat wastewater in Sweden today is by a combination of an activated sludge process and a chemical treatment. These processes are not very energy efficient and may not be the most environmentally friendly. That is why it is interesting to evaluate new alternative methods to see if they can be less harmful to the environment and help to a lower resource consumption. New techniques are tested in a pilot installation at Hammarby Sjöstad, Sjöstadsverket. To be able to evaluate these techniques in a wide perspective system analyses are conducted where different impacts can be considered, advantages and disadvantages in the systems.Five system structures for water treatment have been constructed in Matlab/Simulink in this study.
Merger of equals, fallet Arla Foods
Vid millennieskiftet stod det klart att två av Europas största mejeriföretag skulle fusioneras ihop till ett företaget. Svenska koncernen Arla och den danska MD Foods gick ihop i en så kallad merger of equals vilket innebär att fusionen äger rum mellan likvärdiga parter.Efter fusionen går det att ifrågasätta om fusionen verkligen blev jämn. Eftersom både styrelseordförande och VD:n är danskar samt att koncernledningen till stor del är danskt. Huvudkontoret placerades även i den danska staden Århus. Det är därför osäkert om begreppet merger of equals var ett knep för att få företagets ägare och medlemmar att gå med på att fusioneras.
Fysisk arbetsmiljö i storhushåll - Ur arbetsledares synvinkel
I Sverige upplever dagligen över 1,5 miljoner sysselsatta, sitt arbete som ergonomiskt påfrestande. Inom storhushållsbranschen förekommer många av de vanligaste arbetsmiljöproblemen som t.ex. buller, tunga lyft, dåliga arbetsställningar, bristande ventilation, hala golv, kemiska hälsorisker och farliga maskiner. Arbetet i storhushåll är ofta fysiskt tungt utan att hänsyn tas till att flertalet arbetstagare är kvinnor. Till följd av detta är belastningsskador vanligt förekommande i branschen.
Budgetarbete och organisationsförändring - en studie av budgetprocessen i Borås stad
Alla typer av organisationer använder sig av budget. Budget är en plan som hjälper till att förutsäga framtiden. I kommuner används budgeten som ett verktyg för att visa kommunens omfattning och inriktning av den verksamhet som de bedriver. Kommuner kan använda sig av olika typer av budgetar som till exempel rambudgetering och behovsbudgetering. Kommuner har olika förutsättningar för att bedriva sin verksamhet utifrån antalet invånare, befolkningsstruktur och geografiskt läge.
Ekonomistyrning inom individ- och familjeomsorg : "Sen om himlen ramlat ner och alla har blivit funktionshindrade, det spelar ingen roll, för det ni hade innan ? det får ni nästa år ändå."
The purpose of the study is to describe how financial management functions within the individual and family care services in three mid-sized municipalities.27 interviews with managers and key personnel at three management levels in Örebro, Växjö and Jönkö-ping were conducted using a descriptive approach and qualitative method. In addition governing docu-ments and delineations in regards to these municipalities have been studied.The combined findings show that all municipalities have separate visions and control systems/models for their municipality with focus on management by objectives and politically determined goals, which in-clude economical measurements and requirements for the departments. Moreover, are also tracking sys-tems, which are described as following up on the results thru indicators and/or measurable goals. The municipalities utilize framework financials and budget processing on a high level and its timings appears similar in each municipality.Additionally the study has shown that there is a desire and aspiration to implement central economic goals in all three municipalities. The interviewees describe how they use their leadership to anchor, follow up and create participation in economic objectives and results thru instrumental and institutional leadership.
