The present study aims to examine how teachers write polemical articles. This genre often occurs in national standardized tests in Swedish schools. The study seeks to analyze argumentative structures in the articles. It also categorizes assessment notes written by the teachers in response to each others? articles, by interpreting response texts.    The examination shows that there is uncertainty among the teachers about how to create structures in argumentative text types.

The ambition with this study is to look into and create an understanding for how an intranet can work as a support system in work processes in capacity as a source of knowledge. We want to enhance the understanding for which kind of knowledge that can be coded in and transmitted by an intranet, and which that is lost in this process. We also want to clarify what it takes to get this knowledge, in collaboration with the intranet, to support the work in an organization. It is a qualitative case study at a Swedish bank. It consisted of semi standardized, half structured interviews with five people in one of the bank?s local offices.

This thesis aims to investigate if there are any differences in the value relevance of yearly earnings announcements before (2000-2004) and after (2005-2009) IFRS were implemented for listed companies in the European Union. To assess the value relevance of earnings, an earnings response coefficient (ERC) is estimated using a linear OLS-regression model. The regression model uses accounting earnings per share as the explaining variable, with the corresponding return starting from (but not including) the previous year's earnings announcement date, ending at (and including) the current earnings announcement date, as the dependent variable. This study finds that there is no statistically significant difference between the estimated ERCs for the two periods. Although no statistically significant difference is found, data shows that the R2-values, which measure the explanatory power of the regressions, are higher for the period before IFRS.

The limit for mercury in fish, set by health authorities, is exceeded in about half of the lakes in Sweden. Methyl mercury (MeHg) is the most toxic form of mercury and accumulates in fish. Therefore transformation of inorganic mercury (Hg) to methylmercury (MeHg) is an important process that we need to understand in order to possibly counteract the negative effects of mercury in the environment. The seasonal dynamics of mercury biogeochemistry is likely of great importance for the accumulation of MeHg in the aquatic food web. In thesis the chemical speciation and transformations of Hg and MeHg in bottom waters and sediments is followed in Ängessjön, a small lake located on the east coast in the middle of Sweden. The lake is not directly affected by any industrial pollution and concentrations of Hg in the sediment reflect the atmospheric deposition in this area, as well as processes taking place along the hydrological pathways from soil to lake. Samples from sediment, bottom- and streamwater were collected in average every second month during the period Feb.

The purpose of this study is to investigate how teachers approach communication in their mathematics instruction. The communication involves concepts such as teachers' mathematical language, incorrect answers, and various interaction patterns. In line with this, the study also examines how these types of communication may affect students in the classroom. Furthermore, observations and interviews were conducted with five different teachers in Sweden using an observation scheme and an interview guide. The results reveal that four out of the five teachers use both child-directed and adult-directed language when addressing students at different levels of mathematical understanding.

Chlamydia is a sexually transmitted infection. The infection rates have increased in the last decade. During 2008 the trend rates declined in all counties and regions in Sweden. Chlamydia infections have a geographical spatial pattern differences. This is seen from the national surveillance data report from the Swedish Institute for infectious disease control (SMI).

The purpose of this work was to investigate the adherence to basic hygiene routines among staff and to investigate if there is any difference between the adherences in diverse professions. The purpose was also to study how staff rates their own adherence to current guidelines. Data for the study were collected through observations and questionnaires. Altogether 35 people were observed and 15 answered the questionnaire. Maximum adherence was found in the category of "hand disinfection after patient contact" with a score of 96%.

The lions at Kolmårdens zoo are vaccinated against Feline Panleukopenivirus (FPV). In 1994 there was an outbreak among the lions at the zoo of FPV disease. A retrospective study has been made to measure the antibodytiters in vaccinated lions and lions that lived during the outbreak. An ImmunoPeroxidase Monolayer Assay (IPMA) was used to analyze the titers in the sera from the lions. Lions were divided into five groups. Group 1, 2 and 3 contained lions vaccinated one, two and three times respectively (a total of 40 animals). The lions of Group 4 were born in 2004 (six lioncubs) and were vaccinated according to different regimes and the changes in antibodytiters were followed as respose to vaccination during the spring 2005.

Syftet är att undersöka om Sverigefonder under en nio- sju- respektive femårsperiod genererar riskjusterad över- respektive underavkastning. Målet är därefter att härleda avkastningen till en fondförvaltares förmåga att framkalla en skev fond, alternativt till dennes eventuella selektivitets- respektive timingförmåga. Detta med hjälp av Jensens Alfa, Treynor & Mazuys modell samt Asymmetric Response Model. Ett första delsyfte är att utreda i vilken utsträckning avkastningen kan knytas till det fondbolag som förvaltar fonden respektive fondens förvaltare, antal förvaltarbyten, storlek samt omsättningshastighet. Målet är även att koppla egenskaperna till skevhet, selektivitets- samt timingförmåga.

Germany has experienced low birth rates ever since the 1970s when they fell below the replacement levels of 2,1 children per woman. Since then, their birth rate has been around 1,5 children per woman, which has caused an overall aging population. The consequences of the declining birth rates is that the previous generations are becoming larger than the younger generations. This demographic shift raises concern about how its potential implications might affect different aspects of the country and its economy overall. The aim of this paper is to try to discern the dynamic between the share of the labor force in relation to total population, with the share of pensioners in relation to the total population.

The study concerns the unloading of pigs at the slaughter house, both from the pigs view and from the transporters view. The study has been carried out at the slaughter house (SLP) in Helsingborg, Sweden. It includes a questionnaire to all transporters (65 % response) and a direct observation of the unloading. The transporters handling of the pigs, their use of different equipment and the response of the pigs has been studied. The pigs behaviour at unloading and their reactions to environmental factors has also been studied.

The WT1 gene is a complex gene originally known to suppress cancer in kidneys. Studies of WT1 knockout mice have confirmed the important role of WT1 in the pathogenesis of Wilms? tumour, a tumour which counts for 95% of all childhood renal tumours. In that case the WT1 gene acts as a tumour suppressor gene. Subsequent research has shown that the WT1 gene in many other cases acts as an oncogene, e g in leukemia or lung cancer (even though these cancer forms can emerge as a result of many other aetiological factors).

Modern semiconductor design methods makes it possible to design increasingly complex system-on-a-chips (SOCs). Testing such SOCs becomes highly expensive due to the rapidly increasing test data volumes with longer test times as a result. Several approaches exist to compress the test stimuli and where hardware is added for decompression. This master?s thesis presents a test data compression method based on a modified facsimile code.

In this study I investigated whether the strength in the manual response for emotional and neutral stimulus search arrays can explain some of the difference in reaction times (RT:s) for emotional stimuli, or not. Earlier, perceptual, cognitive and attentional processes has mostly been used to explain the variance in RT:s. Thirtythree individuals were asked to, as fast as possible, detect a target picture among distractor pictures in 3 rows x 4 columns arranged search arrays. The pictures were categorized in fear relevant animals (snake, spider) and neutral animals (cat). The results showed, more correct responses for cat target.
