The purpose of the thesis is to study whether any special professional norms exist with regard to principals’ leadership of the democratic mission which is presented to the schools. The aim is to identify norms in order to be able to later analyse and understand them. Norms exist in groups of various types, and by using the term “norm” I am addressing the actions of principals, rather than their i
Since IPCC AR4 in 2007, climate science has made continual progress for more than three years. This is reflected both in the number of new scientific papers, but also in the development of the research agenda. By and large, the physical climate science as assessed by IPCC Working Group I in AR4 appears robust in the light of more recent research. The knowledge base is of course continuously develo
Popular Abstract in Swedish Resultaten som presenteras i denna doktorsavhandling visar att det går att spara stora mängder energi genom att använda samma typ av värmeväxlare, som normalt används i bilar och lastbilar, i livsmedelsbutikernas kyldiskar. För att hålla maten kall när den ligger ute i butiken cirkuleras en kyld luftström runt i kyldiskarna. Denna kyls i en så kallad värmeväxlare som Provisions are stored and displayed in supermarkets and grocery stores, at a temperature lower than the ambient, in display cabinets, which are responsible for a significant amount of the energy use in this sector. During the 1990s, major changes in the regulations governing the use of synthetic refrigerants took place in Sweden. This resulted in many refrigeration systems being converted to syste
Popular Abstract in English Over thirty years of experience shows that energy efficiency is the easiest, fastest, and cheapest strategy to reduce today’s rampant energy use. To enhance energy efficiency, governmental intervention and business strategies are needed. The question of which governmental policies are the most effective to support energy efficiency remains unanswered. Policy learning anExperience shows that energy efficiency improvements are the most cost-effective path to meeting global energy challenges. To promote energy efficiency, various policy instruments have been in place since the 1970s. Nevertheless, energy efficiency improvements still lag behind their potential in the building sector, which indicates that there is a lack of knowledge about the performance of policie
One of the most important factors governing durability of concrete structures is reinforcement corrosion, and to prevent degradation associated with it, it is desirable to use large concrete covers. However, if the concrete cover is increased, the majority of design methods will predict that the crack widths at the concrete surface increase significantly. This can be contradictory, since the same

Abstract The increased focus on social capital theory has made its way into labour economics. This has led to the creation of a vast literature about the use of networks and informal search methods in the labour-market, a literature that to some extent also deals with immigrants search behaviour and their relatively high unemployment rate. Characteristic for the literature in the area is the lack
Betsafe is still a young company that have seen a great success in a short span of time. To remain successful it is therefore important that they don’t become complacent and remain visionary. However, a successful company must also balance its risk‐taking. In the end it is vital to find the right opportunities that fits the company and of course to be able to make the right decisions. In this proj
Under början av 1900-talet införde alla nordiska länder, förutom Norge, en möjlighet för frihetsberövade kvinnor att medföra sitt spädbarn i anstalten under straffverkställigheten. Regleringarna grundades på arvsbiologiska aspekter, då det var vanligt att de små barnen fortfarande ammades av sina mödrar och de var beroende av modersmjölken för att överleva. Med tiden har dock regleringarnas syfte In the beginning of the 20th century all Nordic countries except Norway introduced a possibility for imprisoned women to bring their infants with them during their sentence. The legislation was considered necessary due to the fact that the infant still was breast-fed by their mother. Child psychologist and psychoanalysist John Bowlby (from Great Britain) developed the affiliation theory during th
Abstract Toxic cyanobacterial blooms can form in both freshwater and marine environments, which could threaten the health of human beings and animals. The genera that are known for causing the scums in freshwater are Anabaena, Microcystis, Cylindrospermopsis and Planktothrix. In order to control lake water quality and minimize the potential health risk associated with the cyanobacterial blooms, th
A risk evaluation with regards to fire safety has been performed at Torpa Stenhus. The focus of the evaluation was the safety of the people inside the building in case of a fire. As part of the education for future fire protection engineers at LTH a risk evaluation report is performed in the course Brandteknisk riskvärdering (VBR054). Torpa Stenhus was built during the 15th century and is located
Climate change places pressure on rural land in terms of carbon sequestration, biomass for substitution and adaptation of crops. Land use can both positively and negatively influence the runoff regime, therefor a catchment perspective is important when developing climate strategies. This is also important with respect to flood-risk that will increase with climate change. Here I investigate if ther
Geofysiska mätmetoder kan tids- och kostnadseffektivt skapa tvådimensionella (2D) och tredimensionella (3D) modeller som avspeglar geologin och som kan användas som ett verktyg för kartläggning av grundvattentillgångar.

Bostadsmarknaden har genomgått flertal förändringar sedan 1990-talet och haft en positiv trend under 2000-talet. De senaste åren har marknaden för nyproducerade bostadsrätter förändrats på grund av kreditrestriktionerna som införts. Fastighetsutvecklare har svårare att hitta köpare som är villiga att teckna bindande förhandsavtal och det råder en viss osäkerhet på marknaden för nyproducerade bostaThe housing market in Sweden has had a positive trend since the 1990s. In recent years, the market for newly produced condominiums has changed due to credit restrictions enforced by new legislation. To sell condominiums for new production, binding preliminary contracts (in Swedish: förhandsavtal) and special tenure contracts (in Swedish: Upplåtelseavtal) are used. In those contracts the seller und

One third of Sweden's total annual greenhouse gas emissions originate from the transport sector today and great changes are thus needed in order to reach the net zero emission target by 2045. One of the most important measures discussed is an increased electrification of the transport sector and a solution with potential to contribute to this transition is electric road systems (ERS), where ve
Salinity gradient energy (SGE) can play an important role in the energy transition from fossil-based sources to renewable sources. Its potential is estimated to be around 625 TWh·a-1 corresponding to 3% of global electricity consumption [1]. SGE sources are most abundant in the estuaries where rivers meet seawater. However, it is also available in different forms such as brackish water, brine etc
Internationella skiljeförfaranden blir allt vanligare i den globala ekonomin. De sker ofta i neutral jurisdiktion där ingen av parterna, till synes, gynnas av vald jurisdiktions lagar. Skiljeförfaranden anses ofta som en av de bättre tvistelösningsformerna då de är effektiva, förutsebara och parterna får själva utforma förfarandena. Det är speciellt fördelaktigt om de rättsliga relationerna mellan
Fjärrvärme är en teknologi som har stor potential att bidra till att möjliggöra ett fossilfritt samhälle. För att uppnå denna potential, finns det dock en del förbättringar som måste göras för att förbättra fjärrvärmeverksamheten i stort, minska förlusterna från systemen och därmed öka konkurrenskraften hos fjärrvärme som teknologi. Ett flertal studier har visat att ett sätt att göra detta, och däDistrict Heating is a technology with the potential to enable a fossil-free society. However, to realize this potential, some improvements need to be made in order to improve District Heating operation at large, decrease losses in the systems, and thus increase the competitiveness of District Heating as a technology. Several have shown that a possible solution, to increase the efficiency of Distri
