Korrelation mellan hållfasthet i kalkcementpelare och oförstärkt lera : En studie av sonderingar utförda på projekt BanaVäg i Väst

A today common soil reinforcement method is the installation of lime-cement columns. Lime-cement columns have been used since the 1970?s and have been a useful method for stabilizing soil at great depths. It is mostly used for stabilizing road and railway embankments because the method is economically viable and the columns are easy to install. The total costs for the installation of the lime-cement columns is dependent on the numbers of installed columns, what percentage of lime and cement that has been used and the pattern in which the columns has been installed.

?Vad spelar det för roll då om inte alla syns på bild?? : En studie av representation i förskolans miljö

The aim of this study is, from a norm-critical approach, to find, investigate and analyse human representation in the visual culture of one preschool in order to understand if the children enrolled are represented or not. The research questions are: In what ways is there imagery of human representations in images and materials designed for play? What skin-colors and origins are dominant in the data collected?We carried out a qualitative study in the form of visual ethnography. This method allowed us to use a combination of different data collection tools such as photography and ethnographic field notes to collect our data. The photographs we took of images and material used for play, was then analysed through semiotic picture analysis.

Att organisera för lärande : En studie av samband mellan gruppens ålderssammansättning och förutsättningar för barns lärande i förskolan

Syftet med denna studie är att undersöka om det finns några mönster och samband i hur förskolepedagoger upplever förutsättningar för barns lärande beroende på ålderssammansättningen i gruppen. Studien är kvantitativ med webbenkät som metod för insamling av data från pedagoger. Undersökningen omfattar alla förskolor inom en kommun i Värmland, totalt 55 kommunala avdelningar och 144 pedagoger. Följande ålderssammansättningar ingår i studien: åldersindelade grupper, småbarnsavdelningar (1-3), avdelningar för äldre barn (3-5) och syskonavdelningar (1-5).Studien har sin utgångspunkt i interaktionistiska teorier, vilket innebär att förskolans verksamhet studeras utifrån olika samspelade aspekter, faktorer och nivåer. I studien ses förutsättningar för barns lärande i förhållande till förskolans kvalitet, vilken i sin tur tolkas som ett komplext fenomen som skapas i samspel mellan olika faktorer på struktur-, process- och resultatnivåer.

Genetiska studier på fågelinfluensa :

In the spring of 2006 we had our first outbreak of avian influenza of highly pathogenic H5N1 (HPAI) among wild birds in Sweden. This disease have impact on poultry industries world wide. Sporadically the virus infects other species than birds and we now know it can even cause fatal infection of humans. There are not yet any confirmed cases of transmission of the disease between humans though a suspected case in an Indonesian family is under investigation. If a mutation occurs that changes the pathogenicity and host affinity to humans we are at a risk of a new pandemia, perhaps like the Spanish flu in 1918-1920.

En arena för alla? : En studie om normbrytare på Stockholms stads idrottsplatser

In Stockholm there are currently five women, out of a total of 102 employees, working in public sports arenas. In sports arenas men are numerically superior amongst the workers as well as the visitors. These arenas are in many ways male dominated, masculinized environments. In this essay I investigate the reasons behind the uneven distribution, in terms of gender, among sports arena workers. I do this by interviewing seven female sports arena workers (the five current and two former), and by observing their workplaces.

Intellektuellt kapital : En fallstudie om problematiken i kreditbedömningsprocessen

Bakgrund och problem: Det föreligger en problematik i kreditbedömningsprocessen som berör svårigheten att bedöma ett  bolags värde samt dess återbetalningsförmåga. Vanligtvis värderas organisationer utefter sina finansiella rapporter men eftersom de inte alltid inkluderar immateriella tillgångar i form av intellektuellt kapital skapas en informationsasymmetri. Informationsasymmetrin kan vara en orsak till eventuella felbedömningar av ett företags riskutsatthet och framtida utveckling och således till ett nekande av sökt kredit. Forskare lägger skulden på redovisningssystemet men vi vill lyfta frågan om problemet även kan ligga i kreditbedömningsprocessen.Syfte: Syftet med föreliggande studie är att undersöka hur banker, i rollen som finansiärer, behandlar intellektuellt kapital hos kunskapsintensiva företag vid en kreditbedömning. Avsikten är att beskriva, tolka samt reflektera kring kreditprocessen för att påvisa vilken betydelse det intellektuella kapitalet har för kreditbeslutet.Metod/Empiri: Studien har utförts som en kvalitativ undersökning baserad på intervjuer och praktikfall.

Soil fertility status and Striga hermonthica infestation relationship due to management practices in Western Kenya

Striga hermonthica, a parasitic weed, has long been believed to be correlated with the declining soil fertility status. However scientists have recently come to question this statement since some recent studies have shown contradictive results. To investigate whether soil fertility status and infestation of Striga hermonthica were correlated and the impact of it were caused by farmer management, 120 farmers in Western Kenya, where Striga hermonthica infestation is prone, participated in this study. In three districts with two sub-locations each, farmers answered a structural questionnaire and identified two fields, one with high and one with low soil fertility. These fields later came to be the basis for this study and soil were therefore also sampled from them.

Fiskevård och delning av fiske vid lantmäteriförrättningar : Studie av FBL 3 kap 8 §

AbstractThis bachelor thesis was performed at the Royal Institute of Technology in Stockholm on behalf of the Land Survey Authority. The thesis is about fish conservation and division of fishing water at official duty. It is the Land Survey Authority that examines division of fisheries, but before a case can be implemented, certain requirements must be achieved such as FBL 3:8, which prevent divisions that are deleterious for fish conservation. The purpose of this thesis is: to obtain a clearer view how FBL 3:8 should be applied in practice, how the application differs between the offices in central Sweden, and how fish care is regulated at both international and national levels.At an international level, in EU the commercial fishery is regulated through the common fisheries policy (CFP). The fisheries policy consists of a reform that will last for 10 years.

Kina i Afrika : En studie av Kinas afrikapolicy

Since the beginning of the new millennium, China has opened itself to the outside world and in an enormous pace increased its contacts and relationships with other countries. The trigger to these dramatic changes of economic and foreign policies is the insight that China can no longer sustain its rapid economic growth, largely based on industrial production, on energy and raw materials from China alone.Good relations with African countries have been of highest priority in China?s strategy of ?Going global?. The new African policy is based on the two principles of mutual benefit and non-interference in internal affairs ? as opposite to the West?s strategy of structural adjustment programmes (SAP), which include massive interference in internal affairs.

What are the positive and negative implications for the empowerment process? Another aim is to find out the role of local and international support in this process. The theoretical framework of this study revolves around the concepts of gender, power and empowerment. Our methods are qualitative interviews and observations.

Organisatoriska mellanrum - En övergripande förklaring till ägarlägenhetens dåliga genomslag?

In year 2009, a new housing form (here referred to as "owned apartments", in Swedish called "ägarlägenheter") was introduced in Sweden. Owned apartments are in many countries the dominating form of housing tenure, but in Stockholm, to where this thesis is delimited, only four have been established in four years. There are many possible reasons for this low establishment, but the thesis writers believe the main reason to be that the owned apartment is situated in an organizational gap. With the hypothesis that the owned apartment is situated in an organizational gap and that there are opportunities to overcome this gap through interorganizational collaboration of the players on the market, this thesis strives towards examining if this is the case.By using Burt's theory of structural holes the concept of organizational gaps are elaborated to fit this context, since this area is previously unexplored.The data has mainly been gathered through in-depth interviews but also through secondary sources such as previous theses and newspaper articles. It has appeared that the majority of the central players are characterized by conservatism.

Det krympande klassrummet : En studie av högstadielärares förutsättningar i ett reformerat skolsystem

Since the 1990?s the Swedish school system has undergone major and recurring structural reforms. Two of the most comprehensive changes has been the shift of primary schools as an integral part of the welfare state to the responsibility of the municipalities as well as the introduction of free school choice for the students. Through two months of participant observations and semi-structured interviews this thesis seeks to answer the question of how these reforms has come to effect the work of teachers in a medium sized public school in a small municipality in the outskirts of Stockholm. Earlier research has shown that public schools in socio-economically vulnerable areas are disadvantaged due to the reformation of the school system (Beach & Sernhede, 2011; Östh, Andersson, & Malmberg, 2013).

Voluntary Redundancy - A tool for restructuring or a temporary pain reliever?

This thesis has two aims: The main purpose is to describe and illustrate how a large Ltd. company can use voluntary redundancy as a tool for restructuring. The additional purpose is to challenge the concept of voluntary redundancy trough outlining alternative ways of reaching the intended achievements of the voluntary redundancy programme. The theoretical framework that has been used primarily contains knowledge assets theories. The chosen theories are intellectual capital and knowledge management theory to approach and analyse the empirical findings.

Avskaffad revisionsplikt för småföretag : Konsekvenser och möjligheter för redovisningskonsulter och revisorer

Background for the research problems: Small companies are very important for the economic stability and development, something which the economic crises in recent years have underlined. Therefore it?s important to minimize administrative costs for smaller companies and also in other ways facilitate their further development. For these reasons accounting has been simplified and auditing abolished for smaller companies in many countries. In Sweden auditing for small companies was abolished nearly three years ago.

Gruppen som pedagogiskt redskap : En studie om gruppstorlekens pedagogiska betydelse i undervisningen.

The focus of this thesis is the group as a pedagogical tool. It investigates whether and how what is known of group size can help further schools in fulfilling knowledge and democracy goals and moreover how such knowledge can influence the principals? management. The mission of school education is to provide the basis for each pupil?s individual development and in the end it is pupils? individual performances which are graded.
