Trycksår : ? undersköterskors kunskaper om att förebygga trycksår

Background and aims: The population of older people in our society is increasing. Agerelated changes in the skin results in a diminished perception of pain and pressure and a decreased microcirculation in the skin affects its ability to adapt to injury. Occurrence of pressure sore on geriatrikal clinics are 5-10%, witch means that between five and ten thousand patients gets daily treat for pressure sores. When the patient gets a pressure sore the need for help increases. A common apprehension is that if the patient?s affects with pressure sores it?s because of deficiency in care.

Lärare och skolbibliotekarie ett udda par som bör dra jämnt. En studie i samarbete på en högstadieskola

This Masters thesis concerns collaboration between teachers and librarians. Three theoretical perspectives, profession, power and legitimacy, are used to analyse the results of written interviews with eight teachers and one librarian at a comprehensive school. We did not find evidence of any deeper collaboration between teachers and the librarian. The effects of profession had little impact on the relation although the involved parties seemed to appreciate differences in education and points of view. The teacher retains power over education and grades while the librarian holds sway over the physical library and the purchase of books and other media.

Att skriva sig till läsning : Möjligheter och begränsningar ur ett pedagogiskt perspektiv

This thesis intends to analyse conditions for a successful implementation of consociational democracy, as a democratic model in Afghanistan. The lack of critical reviews regarding the democratisation-process in Afghanistan initiated the purpose of this study.Lijpharts democracy model was used as the basis in the comparative study. Along with empirical evidence regarding how the complex process of democracy in Afghanistan is progressing, the study investigated whether the identified conditions occurred or not.The choice of which democracy model to use can be crucial for the democratic possibilities to even survive and become established in conflict-affected communities. The principle of consociational democracy is that it is an empirically based normative model that aims to organise the state in a way that works against the risks of majority domination and oppression against the minority.The empirical case study revealed that a majority of the conditions were not met, which then can counteract the possibilities for consociational democracy in Afghanistan. The study has critically examined the prospects for the success of consociational democracy in Afghanistan, and it can be assessed that there is a limited probability for a successful applying of this model..

Jämförelsestudie mellan AP-fondernas Sverigeportföljer och storbankernas Sverigefonder 2002-2006

The first four AP-funds have a well-diversified Swedish portfolio, which is managed in similar way as the largest Swedish bank funds. Up until today, there has not been any comparable study that focuses specifically on this part of the AP-funds. Our aim is two-folded; First we will look at how well the AP-funds have managed their Swedish assets compared with Swedish funds of the four largest banks in Sweden during 2002-2006. This will be done by looking at some important key ratios and both absolute and active return. Secondly we will present a descriptive analysis of the management structure within the respective organisations, to be able to draw conclusions regarding the possible deviations in investment return.

När förmänniskan blev den moderna människan

The subject of this bachelor-level thesis in archaeology in the transition from archaic sapiens to anatomically modern humans, and what might have caused this transition. A part of the study aims to prove or disprove whether an increased consumption of shellfish might have caused this development. Another part of the essay deals with the connection of said evolution and the suggested emergence of cultural and ritual practices in South Africa circa 100 000 BP and an evaluation of the arguments concerning the aquatic ape hypothesis, and their usefulness for the subject.The result of investigation of the theory about the increased consumption of marine resources as a probable cause of the last biological step of creating our species points to the conclusion that it is a probable explanation. There is even some evidence that there could be a connection between consumption of marine resources and the "Out of Africa 2"-theory. It is harder to find a proven connection between the suggested emergence of cultural and ritual practices, even some evidence seems to strengthen the idea.

Patienters upplevelser av epiduralanestesi i samband med kirurgi - En intervjustudie av epiduralanestesin

ABSTRACTIntroduction: An increasing number of patients in Sweden receive epidural anaesthesia (EDA) in connection to surgery. Caring for patients with acute pain is a responsibility that is strongly established within the profession of the nurse anaesthetist. If the care provided by the nurse anaesthetist for patients who receive epidural anaesthesia is to evolve then further insight and knowledge is required regarding the individual´s experience.Aim: To describe patients' experiences in receiving epidural anaesthesia based on an earlier perioperative start-up of the EDA.Method: Based on a qualitative approach, the aim is to conduct semi-structured interviews with patients who receive EDA in connection to abdominal or gynaecological surgery. Research subjects' statements in the context of the interviews will be transcribed and then analysed using qualitative content analysis. In order to evaluate the chosen method regarding data collection and analysis model an exploratory pilot study was conducted.

Kan markfuktighetskartor användas för att hitta skogsmark med hög bonitet? : ett gis-baserat försök med dtw-index och laserskannad övre höjd

The depth-to-water-index (DTW-index) is derived from digital elevation models (DEM) to map soil wetness, in terms of distance from soil surface to the ground water table. The aim of this GIS based study was to investigate the existence of a relationship between DTW-index and forest site productivity (SP). The belief of such an assumed relationship was based on knowledge that the ground water level is related to site properties that can either promote or impede tree growth. Data primarily comprised rasters of the Krycklan catchment in northern Sweden and depicted DTW-index and a laser scanned vegetation height. The 100th height percentile of each pixel in the vegetation raster was assumed to mirror the top-height, letting it act as a relative measure of SP within a delineated area of equal stand age.

Antibiotic resistance associated with bacteria in irrigation water : a case study of irrigation ponds in Southern Sweden

The focus of this project was to characterize the occurrence of ESBL-­?producing bacteria in two irrigation water ponds in Southern Sweden. Samples were taken from two ponds nearby each other, from which analyses were made based on levels of community and individual isolates. Community samples were used for attempts for characterization of resistance patterns in irrigation water using the Omnilog PM-­?plate system. The growth of community microbiota in the presence of the following antibiotic substances was assessed; amikacin, gentamicin, kanamycin, penicillin G, ampicillin, piperacillin, trimethoprim, potassium tellurite and ciprofloxacin. Isolates were pure cultured using semi-­?selective media: LB, Rainbow Agar, mEnterococcus, 0.1 TSA and VRBD. A total of 177 isolates were isolated randomly. Each isolate was identified using the Omnilog GENIII-­?system of biochemical characterization. Further, the isolates were tested on Brilliance ESBL-­?agar for their ability to grow. Out of the total number of isolates, 30 were selected, preferably Enterobacteriaceae or Pseudomonas spp., based on their high similarity to library strain during the identification in the Omnilog-­?system. These were further characterized using Etest-­?sticks. Three selected strains were picked for further analyses using exogenous isolation for attempts to simulate horizontal gene transfer, and Omnilog PM-­?panels containing various antibiotics of interest. Selections of samples were chosen for molecular tests targeting plasmid-­?borne resistance genes CTX-­?M1, CTX-­?M2 and SHV. The method for assessing community-­?resistance patterns showed ambiguous data that was difficult to interpret; further optimization is recommended. For all tested PM-­?plates, generally greatest differences between substances were found among wells with the strongest concentration of antibiotic substance. A total of 175 isolates displayed ability to grow on ESBL-­?agar. Etests confirmed ability of isolates to resist many ?-­?lactam antibiotics and many were clinically resistant to certain substances. No plasmids were transferred during exogenous isolation. During molecular tests, a few matches were found for the CTX-­?M1 gene. Isolates analyzed with Omnilog PM-­?plates showed resistance to most compounds tested. The isolates showed greatest resistance toward penicillin G, ampicillin, amikacin, kanamycin and trimethoprim. In the study, it was established that resistance among bacteria was frequently occurring in the irrigation water, and ?-­?lactamase producing bacteria was very common. Extended studies are needed to assess the frequency-­? and occurrence of horizontal gene transfer (HGF) in this environment. Although some potential corresponding data is found, it is at this point not possible to determine whether the resistances are due to antibiotics used in veterinary medicine, human medicine or one additional reason is travel and trade. in irrigation water using the Omnilog PM-­?plate system.

Från top down till bottom up : - Att förklara och utvärdera psykosocialt arbete inom hälso- och sjukvården

Today, activities funded with public funds needs to present relevant and reliable information which shows the results obtained. Requirements increase in welfare activities to be run based on scientific, empirical knowledge. This applies particularly to social work. The social work is, however, poorly researched in areas such as knowledge of interventions in the content, context and effects. One way to evidence-base social work can be to conduct regular and qualified assessments.

Med avfall upp till knäna - En osteologisk studie av tafonomi och medeltida avfallshantering i kvarteret Blekhagen i Lund

The subject of this master level thesis in historical osteology, is a study of waste management in the medieval town of Lund. The aims of the study is achieved through looking at the taphonomic aspects of bonefragments from the quarter Blekhagen. The study is divided in two separate sections, one that is a litterature study of what is known about waste management, and another one that contains a taphonomic and spatial analysis. Through examination of the taphonomic variables weathering, average weight and trampling and a spatial analysis, I am able to deduce that there are signs of controlled waste management in the material. It is not possible to draw any general conclusions about waste management in the medieval town however.
