Framtagning av normalt referensintervall för RDW och retikulocyter på hematologiinstrumentet ADVIA 2120
Erythropoiesis is a complex and carefully controlled process which is mainly regulated by erythropoietin. Using flow cytometry cells in a blood sample can be analyzed one by one. ADVIA 2120 using flow cytometry for analysis of red blood cells (RBC) and reticulocytes. Red blood cell distribution width (RDW) is a component of the RBC method. RDW indicates size variation on erythrocytes and is measured as a percentage of the mean cell volume (MCV). By measuring the RDW anemia can be divided into makrocytic, microcytic or normocytic. Reticulocytes refract light more strongly than red blood cells because they contain some cellular debris. The number of reticulocytes in the peripheral blood reflects erythropoiesis in the bone marrow. The purpose of this project was that by approved methods to establish reference ranges for the parameters, RDW and reticulocyte counts.The individuals who participated in the study, n=124, were considered healthy and had varying ethnicity. Reference subjects had not donated blood the last six months and participation in the study was voluntary.The statistic evaluation includes examination of distribution, and reference ranges for both men and women were established using the 2.5:t and 97.5:t percentiles. The calculated reference interval for RDW was between 12.0 ? 14.3% and the calculated reference interval for reticulocytes was between 38.0 ? 112.8 x109 cells/L. The results showed a significant difference between males and females for the parameter reticulocytes was seen. The difference indicates that different reference ranges should be established for men and women (p<0,0001). No significant difference between males and females were seen for RDW (p=0,74) indicating that the same reference ranges can be used for both men and women. .
Betygsättning i Idrott och hälsa 1 : Likvärdig bedömning utifrån lärarens perspektiv
SummaryPatients with burn injuries involving more than 20 percent of the total body surface area lose a lot of fluid and are in the risk of developing a severe hypovolemia. Fluid resuscitation is a corner stone in burn care and is important for preventingfurthercomplications. The most common resuscitation formula is the Parkland Formula. Hourly urine output is a measure used to evaluate if the fluid given is sufficient enough to maintain a sustainable tissue perfusion. Inhalation injury, abuse of alcohol and drugs are some of the factors that may increase the amountoffluid needed.
Medical Care : En jämförelse mellan kursinnehållet och dess utförande i Sverige och i Danmark som leder till ett internationellt certifikat i Medical Care
This thesis has been done at the powder department (GH) at AB Sandvik Coromant in Gimo. With a rheometer measurements has been made on raw materials and powder blends. The focus of this report has been to find correlations between raw material powders and press data, comparisons have also been made between raw materials and powder blends.The rheometer can show information of how a powder act in flow conditions, together with air and with pressure. Analyses has been done comparing the rheometer data with press parameters (for example: rejected orders, weight variations and the compaction pressure) with the goal to find correlations between the powders flow properties and the powders compaction in production.The measurements and analyses have been showing that the powder flow properties depends on the powders composition and that properties like flow rate, aeration and permeability varies between powder blends and batches of the same powder sort. It seems to exist a correlation between the pressure force and the flow rate of a raw material.
Kommunanställdas uppfattning om och nyttjande av kommunens friskvårdsinsatser.
The personnel policy program for the employees in studied municipality includes guidelines for the working environment, saying that health promoting activities is offered to all employees. Objective: To investigate how these activities were used and how the staff perceived the activities offered. The aim was also to find out how well the information about current health promotion efforts reached the staff.Method: A qualitative approach was used in the form of interviews. The sample consisted of municipal employees from seven different work sites. A total of 12 women aged 32-52 years participated. The interviews were recorded and a hermeneutic theory was used to interpret the results.Results: The results showed that most informants used some form of fitness activity. In most cases health care-time was used for anything from walking to organized workouts. The great barrier was lack of information and lack of trained and dedicated health motivators. In several cases, informants had no knowledge about what a health motivator is supposed to do. The informants own suggestions for health promotion interventions included stress management and foot care.Conclusion: The survey showed that respondents were poorly informed about which wellness activities the municipality offered. The result could also be interpreted as a communication gap between the local authority, health motivators and the employees. A request for group activities was detected. .
Bedömning och betyg : grundskolelärares uppfattningar kring tidigare och tydligare kunskapsbedömningar
The school is under constant change and school reform on the conveyor belt. In 2009 the Swedish government introduced new directives for the elementaryschool, including multi-national sample, written testimonials from grade one and grade with several grades rose from grade six. The purpose of this study is to examine currently active primary teacher perceptions of the pupils' learning and development might be affected by those earlier and clearer knowledge assessments, and how teachers perceive this reform on the basis of the Swedish school's motto "a school for all". The study was carried out with a phenomenological approach where the method has been depth interviews with five active primary teachers from grades one to six in a school. The results show that teachers perceive that the earlier and clearer assessments will affect students differently according to student performance and knowledge.
INTERAKTION I EN VIRTUELL GRUPP : gapet i det normbildande ramverket
The existence of social networks on the Internet is today seen as broad, and the number of users of the network is increasing. There seems to be many reasons to which people are using the social networks. Within the network, users can for various reasons create groups with different objectives. One of the reasons is that groups are created in order to influence a company. With a perceived feeling that companies handle the problem differently, we assume the source is the uncertainty about what the groups really are.
Locally produced pork ? Västra Götaland
The interest for locally produced food has increased the last couple of years, and some consumers have a willingness to pay a premium for niche products like locally produced food. At the same time it seems like the Swedish pig production are in a negative development period. This study tries to see if locally produced pork could be a possible factor which might affect producers in the county of Västra Götaland views on different aspects regarding their production. Consumers of pork and their point of view regarding locally produced pork were also studied. Surveys to consumers and producers were constructed.
Although previous studies claim the opposite, in the two locations (Högsäter and Uddevalla) where the consumer survey were performed, there were more men than women that always bought locally produced pork.
Lätt att få ? svårt att gå : Individens upplevelse av anställnings(o)trygghet kopplat till arbetsmarknadsmodellerna i Danmark och Sverige.
Den danska arbetsmarknadsmodellen flexicurity har blivit mycket omtalad och betraktas ofta i media som en optimal modell, där danskarna sägs vara tryggast i Europa i sin arbetssituation. Förespråkare av både den danska och den svenska modellen hävdar tryggheten som en viktig grund i de respektive arbetsmarknadsmodellerna. I det danska systemet ska tryggheten ligga i enkelheten att få nya jobb, till skillnad från i Sverige där tryggheten ska ligga i svårigheten för arbetsgivaren att avskeda personal. Utifrån denna bakgrund är syftet med uppsatsen att jämföra individens upplevelse av den arbetsrelaterade anställningstryggheten i Danmark och Sverige. Finns det skillnader i de faktorer som påverkar den upplevda anställningstryggheten och går dessa att koppla till respektive lands arbetsmarknadsmodell? För att genomföra studien skapades en enkät som delades ut till 30 respondenter i respektive land.
Psykisk ha?lsa vid arbetslo?shet: Pa?verkan pa? arbetsa?terga?ng i ett svensk urval - Unemployment and mental health: The effect on reemployment in a Swedish sample
Mixade vårdsalar, det vill säga där man blandar män och kvinnor, är något som förkommer på sjukhusen runt om i landet och bör uppmärksammas utifrån patientens perspektiv då denne är i beroendeställning av sjukvården och dess vårdmiljö. Det blir allt vanligare att sjukhusen idag har mixade vårdsalar, detta oftast på grund av tids- och platsbrist. Studiens syfte var att beskriva patienters upplevelser av att vårdas på mixad vårdsal på en akut sjukvårdsavdelning inom nedre kirurgi. Studien var kvalitativ med fenomenologisk ansats. En intervjustudie med femton patienter som hade vårdats på mixad vårdsal genomfördes och i resultatet framkom att majoriteten av patienterna upplevde det positivt att vårdas på mixad vårdsal.
Valet av hög revisionskvalité : Vilka faktorer beskriver valet?
This paper analyzes the auditor choices for a sample of 300 predominantly small Swedish firms, all located in Umeå. Our hypothesis was based on the complexity of a firm, the need of external financing, leverage, and the need of extra consultance from the auditfirm. Our definition of auditor quality is based on prior studies, and is frequently used by authors in this area. The assumption is based on that the auditor quality increases with the size of the auditfirm and the degree of the auditor. The auditor quality is therefor depending on the choice between an auditor from the group ?Big 5? or not, and the choice of an auditor with an higher degree.
Vilka faktorer medverkar till att professioner i primärvården förskriver fysisk aktivitet på recept (FaR)?
The aim was to study the factors that contributed to the prescription of physical activity on prescription (PaP) by the professions in primary healthcare. A qualitative method was used in the study.

AbstractTitle: Internal Communication at a large mobile operator (Internkommunikation hos en mobiloperatör - en studie av motivation och upptagningsförmåga av information hos butikschefer)Number of pages: 43Author: Helena IsakssonTutor: Peder Hård af SegerstadCourse: Media and Communication Studies CPeriod: Fall term 2006University: Division of Media and Communication, Department of Information Science, Uppsala University.Purpose/Aim: The purpose of this essay is to gain an insight in how a corporations store managers motivation affects the degree of information they absorb from information channels.Material/Method: The method that had been used in this essay is quantitative. It is based around a questionnaire aimed towards store managers and consequently used it to run regression analysis using the software package SPSS.Main results: The main result of the essay is that the motivation among store managers is positively related to the degree to which they absorb information. Thus, a possible problem exists for the corporation in that they need to make sure that the store managers are and stays motivated. Further, it seems that the longer a store manager has been employed by the corporation the less information is absorbed. The reader should although interpret the results with caution, since the limited sample could bias the estimates.Keywords: Internal communication, organizational communication, motivation, information, information channels and absorption of information..
Kognitiv auktoritet och Wikipedia ? En analys av gymnasieelevers källkritiska granskning av Wikipedia
The main purpose of this master?s thesis is to examine how high school students evaluate the quality of the information available on the online encyclopedia Wikipedia. By doing quantitative research based on questionnaires we expected to find that the means for judging that students use in this situation are most frequently based on a text?s intrinsic qualities in the point of view of its content. It was also our presupposition that 18 and 19 year old high school graduates have received some education in information research and authoritative sources on the Internet.
Skänka pengar och må bra? Ett experiment om produktbaserad biståndsgivning och känslor av välbefinnande
Uppsatsens syfte att ta reda på om individer är mer benägna att skänka pengar om en privatbiståndsorganisation erbjuder produkter i en gåvoshop som sedan skickas till människor i ettredan på förhand bestämt område, jämfört med om organisationen erbjuder mer generellbiståndsgivning till organisationen i stort. Vidare är syftet att testa om det finns ett sambandmellan möjligheten att köpa produkter i en gåvoshop och känslor av välbefinnande hosbiståndsgivaren vid gåvotillfället. Slutligen är uppsatsens syfte att undersöka ombenägenheten att skänka pengar genom möjligheten att köpa produkter i en gåvoshop jämfört med att skänka pengar generellt till en organisation ser olika ut i olika grupper av medborgare.Studien utformas genom ett experiment som genomförs med hjälp av frivilliga påcentralstationen i Göteborg. Hypoteserna prövas genom ett independent sample t-test ochgenom en regressionsanalys med interaktionsvariabler. Resultatet visar att personer som ges möjlighet att köpa produkter inte blir mer benägna att skänka pengar och känner inget högre välbefinnande än personer som ges möjlighet att skänka pengar generellt till organisationen.Däremot verkar högutbildade personer påverkas i högre grad av möjligheten att köpa produkter och det finns ett signifikant samband när utbildning interageras med effekten av typav bistånd på benägenheten att skänka pengar..
