Om familjehemssekreterares handlingsutrymme i umgängesfrågor
The aim of the study is to describe social workers discretion when it comes to the relation between children placed away from home and their biological parents.The study describes how the social worker designs the contacts with the biological parents, for instance the extension for the actual meeting. The results are based on six interviews conducted with social workers who work with foster children. They have responded to questions related to the contact between children and their biological parent. The questions are based on eight vignettes. The contents of the vignettes show different conditions that affect the contact, for example age and foster care attitudes The results of the study have been compared to other previous research in discretion of the social worker and contacts between children and their biological parents.In summary the study shows that there is high degree of independence for the social workers designing their work and that their level of discretion.
Biological control of powdery mildew in greenhouse produced cucumber : an evaluation of two microbiological control agents
Powdery mildew is a serious problem in both field and greenhouse cucumber production and
can cause serious infection and radically reduced yields. Today, powdery mildew is the main
disease in greenhouse produced cucumber.
Disease control should preferably be both efficient and environmentally friendly, which is not
easy to achieve at all times. Alternatives to chemical control of powdery mildews are biological
control, physical control, non-fungicide control and cultivation of resistant or tolerant varieties.
Biological control can be described as the suppression of damaging activities inflicted
of a harmful organism by one or more other organisms, which are called antagonists or natural
enemies. In Sweden, there are currently no registered biological control products available
to control cucumber powdery mildew.
The aim of this study was to investigate the effect of two biological control products in order
to evaluate their ability to prevent or reduce powdery mildew infection to an acceptable level
in greenhouse produced cucumber. In the experiments, different application regimes were also
studied.
Neuropsykiatriska funktionshinder och missbruk: de professionellas syn på riskfaktorer och skyddsfaktorer ur ett utvecklingsekologiskt perspektiv
The purpose of our study is to examine what risk factors can contribute to a child/youth with neuropsychiatric disorders developing an addiction to drugs. We also wanted to find out what protective factors can contribute not to develop an addiction. In order to find out these two different aspects we interviewed twelve professionals to get their view upon the matter. The professionals work within different sectors such as school, healthcare, social services and one of the interviewed is a member of an organization that specialises in neuropsychiatric disorders.When analysing our result of the interviews we used Bronnfenbrenner´s theory on the ecology of human development. What we found was that there are significant risk factors and protective factors on different levels of the child's environment.On the first level, the microsystem, interpersonal relations have an impact on the child's development.
..."för att solen gick inte ner"...... : En studie om morfologi och syntax hos vuxna andraspråksinlärare
Our essay is about the grammar structure that the participants in A- and B- level of a school in the middle of Sweden, in the subject, Swedish as a second language, process. We have collected written productions from an A-level group and a B-level group and made a comparison between them morphologically and syntactically according to the processability theory by Pienemann.Processability theory was applied to Swedish by Pienemann & Håkansson (1999), with five steps in syntax and four steps in morphology. It turned out that the B-level group had much higher processing level of grammar than the A level group and one of the reasons for this can be that grammar is explicitly taught during the first year of studying Swedish as a second language in the school we have chosen to study..
Bäddodling av matpotatis :
This study investigated potato growing in beds as an alternative to conventional ridges.It was based on results from field trials on bed-grown potatoes carried out by Halland Rural Economy and Agricultural Society in 2007, studies of literature and interviews with farmers with experience of bed growing of potatoes.
Due to their shallow root system, potatoes are one of the most drought-sensitive crops. Potatoes are often grown on sandy soils with poor water-holding capacity. Factors such as total yield, tuber size distribution and quality defects are negatively affected when water becomes insufficient. Wide beds have a more flat top which leads to more uniform water infiltration. Further on, beds have lower soil surface area due to its shape, and therefore, retain water more efficient.
In the field trials, which were carried out at the Stjärnarp Estate near Halmstad, potatoes were grown in beds alongside a conventional ridge-grown crop.
Miljö- och samhällsekonomisk analys av behandling av biologiskt avfall
Biogas is a renewable fuel that can be extracted from anaerobic digestion of many differentsubstrates, for example biological household waste. An alternative handling of the waste is tomix it with other wastes and incinerate it in a combined heat and power (CHP) plant. Thisstudy uses life cycle assessment to investigate which type of waste handling that is betterfrom an environmental point of view, anaerobic digestion with biogas production orincineration. The results are based on a case study of a biogas production plant owned by thecompany Ragn-Sells in Vänersborg. The alternative is incineration at a CHP plant inGothenburg.
Socialtjänstens barnskyddsarbete En studie av socialsekreterares riskbedömningar avseende barn som utsätts för våld eller sexuella övergrepp i hemmet.
The overall aim was to examine how the public interest to protect children from violence and sexual abuse at home, is realized by social workers. The study´s central focus was the risk assessments as Social services are obliged to do when they receive a report containing concern that children are being exposed to violence or sexual abuse at home. The study addresses the following questions:o How do social workers go about practically, and what support and knowledge is being used to determine whether the Social services need to intervene for the protection of a child?o What risk and protective factors are taken into account by social workers in the assessment process?o What contextual factors do social workers experience are affecting them in the assessment process?o Which support does the documentation system BBIC provide in the assessment process?The study material was collected through qualitative group interviews, with a modified vignette methodology as tools. The study included a total of twelve social workers, with varying numbers in each interview group.
Kundnöjdhet i revision: En jämförelse mellan företag som reviderats av Big Four och företag som reviderats av någon annan revisionsbyrå
The need for auditing originates from the agency problem that arises due to the separation of ownership and control in companies. The purpose of the audit is to increase credibility of the financial statements that management uses to communicate with owners and other stakeholders. In order for the audit to fulfill its purpose a certain level of quality needs to be obtained. The auditor can also be seen as a provider of a commercial service in which service quality is important. Audit quality can thus be separated into technical quality, which is defined as the probability that the auditor both discovers and reports a breach in the client?s accounting system, and service quality, which relates to the provision of services in general.

Nu kan jag mycket mera : En liten studie i hur delar av Europeisk språkportfolio kan fungera som stöd för formativ bedömning i ämnet engelska, år 4.
The aim of the study is to show how a selected part of the European Language Portfolio, ELP, can support the assessment process for teachers. All the checklists at level A1 and My Language Goals from the Language Biography, a part of the ELP, are implemented and communicated in teaching in a 4th grade class of students. Two teachers are interviewed and both of their classes are compared in the study. One group worked for two weeks with the selected part of the Language Portfolio and the second group followed the regular curriculum for the same period of time. The teachers are interviewed before and after the ELP through support of mind maps.Results show that by using checklists at level A1 and My Language Goals students become aware of their own learning process.
Analys av systemfaktorers påverkan på tillförlitligheten i distributionsnät
In this master thesis outage statistics covering tree years from two distribution grids are analyzed with the purpose to deduce which factors yield outages. The statistics are extensive therefore allowing in-depth analysis of both customer and system related factors. From this starting point and as a model of explanation energy not supplied is studied as the consequence and the measurement of the inconvenience caused by outages. Different methods for calculating energy not supplied are developed and studied and put in comparison to the method used in Network Performance Assessment Model, which is the Swedish frame work for regulating electricity distribution.Analysis of the outage statistics show a relation between the type category of customer and outages that can be deduced to the variance and the density associated with that customer category. Prioritization of different customer categories is elevated also in this aspect.

As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.
Barnens Kostlåda : Ett pedagogiskt arbetsmaterial riktat till förskolebarn. Utvärderat ur barnets perspektiv.
The aim with this master thesis is to analyze a scientific material concerning the context between learning and child/student development, and factors which controls process of learning, to create an image with quality account and teaching in mathematics, which then can raise the mathematical knowledge among students.The phenomena which stand in focus for the investigation is: why there is a negative tendency for development of knowledge in mathematics, among the Swedish students that TIMSSs investigations showed in intercultural comparison within the years 1993, 1999, 2003 and 2007.The method is the ethnographical method, which is based on: analyzing scientific theories about learning child/student development, factors which controls process of learning, and factors which controls process of learning the most and qualitative empiric investigation with qualitatively analyzes the questionnaires, which is about factors which are controlling the process of learning and factors which are controlling the process of learning the most.Result of the theoretical and empiric analyzes shows that factors as school environment, attitude for subjects and teaching, controls and influence the learning. To end a unenthusiastic tendency as a negative development of mathematical knowledge among students that is shown in TIMSS investigation and to elevate the students' performance in mathematics, an elevated qualitative account and teaching in mathematics, by the factors named. Safe school environments as the intercultural meeting place, the teachers influence part to the students' subjects' attitude in mathematics and goal related grading criteria in teaching, is all required for e qualitative teaching in mathematics..
