Risk för våld : Förändring i bedömd risk för framtida våld för rättspsykiatriska patienter dömda för dödligt våld eller misshandel
Abstract. Risk assessment for future violence is an important part of today's forensic psychiatry, and including dynamic risk factors in risk assessment is important because it has been shown that risk can change over time. However, previous research has suggested that perpetrators of homicide are different than perpetrators of other violent crimes. The aim of this study was to describe and analyze risk assessments of future violence for forensic psychiatric patients convicted for homicide (n = 45) and forensic psychiatric patients convicted for assault (n = 91). To do this, differences within the groups and between the groups were analyzed.
Beteenden hos geparder i två stora svenska djurparker
Cheetahs in the wild are declining due to hunting, lack of prey, exploitation of habitats and loss of cubs to predators. Those are the main reasons to why cheetahs are kept in captivity today for conservation. Many cheetahs kept in captivity are seen pacing ? a behaviour that arise when the animal is prohibited from performing natural behaviours. It is believed to being attributed to a lack of stimulation in the environment where they are being held.
Läsförmåga bland högstadieelever utan och med läs- och skrivsvårigheter
The study?s aim was to examine reading ability in secondary school students. The participants; 30 grade 7 students (13 years old) and 30 grade 8 students (14 years old) without literacy problems, and eleven grade 8 students whom either had documented literacy problems or received special education for it, were selected through convenience sample. Text comprehension was tested by three texts which are called the Skobigotexts. Three reading settings were applied: listening, silent reading and silent reading with textsupport.
Vaddå ekonomisk utsatt? : Tankar om ekonomisk utsatthet bland barnfamiljer med utländsk bakgrund i Växjö kommun
AbstractThis thesis is centered on the economic condition and background of immigrants living in Sweden, with focus on Araby, Växjö. To guide us through this enormous work we formulated research questions, which are:Why have foreigners (immigrants) a greater risk of becoming economic vulnerable? How does economic vulnerability effect families with children?What strategies do families adopt under hard economic conditions? What strategies does the society adopt in assisting families, by economic aid, that are economic vulnerable? Our sample was from a school where we administered an open ended questionnaire to selected students and we also had a comprehensive interview session with ten families in the community so as to have a complete picture of their living condition and how they think people are economically vulnerable.We concentrated on the causes, consequences and strategies of how economic vulnerability is handled by immigrants in Sweden. In our analysis we found out, though our respondents? answers, that the causes of economic vulnerable are background, language, priorities et cetera.
Stress, self-efficacy och livstillfredsställelse : Finns det köns och åldersskillnader
ABSTRACTThe aim of this quantitative study was to investigate if stress, self-efficacy and life satisfaction varied with gender and age. The sample was selectively chosen in the municipality, country council, private sector and in the trade business. 237 participants were included in the study, of which 94 were men and 143 were women. Age was split in two categories: younger adults (18-40 years) and older adults (41-65 years). The results showed that there were correlations between the dependent variables: stress, self-efficacy and life satisfaction.
Torkningstekniker i den preoperativa handdesinfektionen - en experimentell studie
ABSTRACTIntroduction: Preoperative hand disinfection aims to prevent surgical site infections. After the preparing hand wash, drying is performed using an aseptic technique. It?s important to dry hands thoroughly in order to achieve the full effect of the alcohol based hand disinfection. Due to the lack of a evidence-based guideline on this procedure, the hand drying techniques differ among operating theatre nurses, depending on which technique seen as the most appropriate.
Soil carbon in small-holder plantain farms, Uganda : a comparison between agroforestry and non-agroforestry
Smallholder farmers in Uganda suffer from declining productivity. With a rapidly increasing population, marginal land is taken into production and the current land
management leads to loss in soil fertility and escalation in soil erosion. There are studies indicating that the use of agroforestry increases soil organic carbon (SOC)
compared to systems without trees. Soils which are high in carbon have many advantages, for example better water holding capacity, which can reduce stress on
crops during drought.
The aim of this study was to determine the effect agroforestry has on SOC concentration in small-holder farming systems in Uganda. The intended system to
study was farms practicing agroforestry methods or not in intercropped plantain (cooking banana) fields.
Följsamhet till en kvalitetsnorm för fall- och fallprevention inom geriatrisk slutenvård : En studie baserad på journalgranskning
PurposeThe purpose of this study has been to investigate the documentation process following the guiding principles of the Quality Norms for Fall Prevention concerning fall risk assessment, risk identification, fall preventive measures, information and the making of an individual care plan.MethodThis study is a quantitative, descriptive and retrospective journal review study. There were 100 journals examine the existing documentation concerning fall risk assessment of patients who received treatment in geriatric patient care. The sample was consecutively.ResultsThe results showed that fall risk assessment was documented in 79 of 100 examined journals. 56 (71 %) of the fall risk assessments were made within 24 hours. In 59 of 100 journals the patient, relatives or former caretakers was asked whether the patient had had a fall within the last year, and in 61 of 100 journals it was documented that the nursing staff had made an assessment that the patient was going to have a fall during his or her length of stay if no preventive measures were set in.The majority of fall risk factors and fall preventive measures were documented within the areas of walking and transfer. It was documented that the patient was informed of fall risk, fall risk factors and fall preventive measures in 15 of 100 journals.
Synoptisk provtagning i vattendrag med eutrofieringsproblem : En studie för att identifiera områden för prioritering av åtgärder
In Halland, agriculture is the major source of eutrophication of water. In the study, synoptic sampling were performed in the three watercourses Nyrebäcken, Skintan and Vinån all located in the county of Halland. Sampling occurred during the period February to May on three occasions with different flow rates: high, low and base flow. Samples were taken in the mainstream and tributaries with intention to show how big the impact of eutrophication it is in the water and to assess the impact of the tributariesThe results show that all watercourses are affected by eutrophication. Nyrebäcken has the highest concentrations of nitrogen and phosphorus in the mainstream, then Skintan and last Vinån.
Hur gör de? : En kvalitativ studie av hur fyra samhällskunskapslärare tolkar och anser sig använda det demokratiska uppdraget och värdegrunden.
AbstractThe purpose of my study was to examine how four social studies teachers in upper secondary school interprets the democratic educational mission and core values, and if they believe that the same values are tools to influence the students' democratic approach and if they think it is possible. It is also the study's minor purpose to make an analysis of my findings and previous research in the area to explain any similarities or differences in the social studies teacher's interpretation and practice of the democratic educational mission and core values. I used qualitative semi-structured interviews as a method in which the interview questions were based on my research questions. The two criteria I had for my sample of respondents was that there would be social studies teacher at a upper secondary school and that I wanted to have two of each sex. Their interpretation and how they think they practice the democratic educational mission and core values are similar.
Optimization of immunoassay parameters in multiplex in the high throughput protein detection technique Proximity Extension Assay
The ability to detect protein-based biomarkers, which are linked to different diseases like colorectal cancer, is very important as a diagnostic tool. Usually complex biological samples like blood are studied which will contribute to different technical issues when performing an assay. The aim with the project is to optimize and develop the high throughput protein detection technique Proximity Extension Assay, PEA, into a 96-plex panel, in hopes of discovering an expression profile for colorectal cancer. PEA was developed by Olink Bioscience and allows specific proteins in a sample to be quantitatively transformed into nucleic acid sequences that are subsequently detected and quantified with real-time PCR. Two proximity probes containing oligonucleotide sequences bind pairwise to target protein and when brought in proximity, a DNA polymerase will extend a hybridization arm from one probe over to the second forming a double-stranded DNA sequence that can serve as a template in real-time PCR.
Taktisk planering med geografisk hänsyn : fallstudie med Heureka PlanVis på SCA Skogs distrikt Liden
SCA is the largest private owned forest owner in Sweden, with an ownership of 2 million hectares of productive forestland. To manage the planning of such large areas and to fit the traditional organization structure of a Swedish forest company, the planning approach is subdivided into three stages; strategic, tactical and operational.
The strategic part, based on a statistic sample of stands, returns a harvest level estimate which should then be implemented at actual sites in the tactical part. This procedure can lead to incompatible solutions as the strategic solution is not necessarily possible to translate into actual sites in the tactical plan. The geographic aspect is important in tactical planning due to the large costs for moving equipment and maintenance of a large number of forest roads.

The primary purpose of this paper is to find the determinants of first-day returns on the Stockholm Stock Exchange. Our research will cover the 1996 ? 2004 periods. Our secondary purpose is intended to find a profitable trading strategy with regard to future IPOs on the Stockholm Stock Exchange. By using regression analysis, focusing on company specific factors and the IPO process, we hope to find a function exhibiting statistical significance, determining future first-day returns from which construction of a profitable trading strategy will be possible.
Finns det ett samband mellan börsnoterade företags resultat och dess värdering?
Background: What is a share and what determines the value of a company? This is a constant issue that many in the financial world are facing. Many argue that there has been some decoupling between stock valuation and how the company in question is developing operationally after the financial crisis that the world faced during 2008-2009.Problem: It is important to distinguish between the company and the share. A company that is good and well maintained may not be worth buying only because of it. The share is judged by other elements also.
Bedömningsgrunder för avsyning av textila material
Dagligen bedömer människan sin omgivning utifrån sina fem sinnen. Då ett intryck ges från omgivningen sker en process, signaler skickas till hjärnan via nerver ifrån det sinne som stimulerats. På grund av den olika uppsättningen nervceller upplevs samma intryck skilt bland människor. I textilproduktion används visuell bedömning genom hela produktionsprocessen, från garn till färdig vara där tyget slutligen kontrolleras i sin helhet vid avsyningen. Avsyningsprocessen sker vid ett avsyningsbord där en operatör matar fram tyg på bordet.
