Sjuksköterskors uppfattning om triagebedömning på en barnakutmottagning
Triage, which means "to sort", determine the priority of the patients need of care. The aim of the present study was to describe nurses? perception of triage at a pediatric emergency department. A questionnaire with open- and closed-ended questions were distributed to all 25 nurses that worked at a pediatric emergency department. The answer frequency was 48 % (n=12).
Rekreationsanpassad skötselplan för Skedalaskogen :
In this master thesis we suggest a recreational directed forest management plan for the
Skedalaskogen. The forest is situated 10 kilometres east of the city of Halmstad and is owned by the municipality.
We have in literature and in research investigated what people like and want in the forest, how to manage the forest for recreation according to for example tree species, mixtures and density. We tried to adapt the forestry methods more to recreational thinking. We have also looked at issues like what is rare and not rare in this part of the country according to nature and forest, where people live and which connection they have to the Skedalaskogen.
The Skedalaskogen is a quite big area, totally 830 hectares. The area have about 100 000
visitors a year.
Bortom historiens slut : En jämförande undersökning av nio U-länders demokratiska utveckling
Bortom historien slut ? Beyond the end of historyAccording to Robert Dahl there are seven criteria that have to be fulfilled in order for a state to be democratic. Dahl also states that there are several factors that effect the development of democracy. In today?s world it is mostly developing countries that have failed to bring about democratic changes.
Avgång av lustgas från luftningsprocessen på Käppalaverket
The requirements for wastewater treatment plants (WWTP) are gradually increasing, partly because of higher incoming loads, which in turn require a more efficient treatment process. In parallel with environmental and economic goals there are also desires to lower energy consumption without compromising the wastewater treatment. Furthermore, there is a demand on WWTP´s to alter eutrophication in aquatic systems through better nitrogen and phosphorus removal. An increasing number of WWTP´s have acquired biological nitrogen and phos-phorus removal. A by-product of this type of biological treatment is the formation of nitrous oxide, which is a potent greenhouse gas.
Självbedömning i förhållande till uppnått resultat : Nationella prov och processbarhetsanalys på sfi
The aim of this essay is to investigate which of the goals in the syllabus, and with that what knowledge of Swedish, four students taking the SFI (Swedish for Immigrants) level 3 course believed themselves to have attained and to compare their self-assessments with their results on the National Test of Swedish for adult immigrants.The method used for the investigation is the individual interview. In addition to taking the National Test, the participants in the investigation were asked to mark the goals they believe themselves to have attained.The results show that the informants who best demonstrated awareness of their own knowledge are able to talk freely about their knowledge and difficulties, and when they mark the goals they believe they have attained, these correspond, on the whole, to how they responded in the interviews.One of the informants finds it more difficult than the others to assess her knowledge. A comparison between her experiences and the National Test results revealed several inconsistencies. For example, she claims that she can communicate in Swedish, but still she didn?t pass the test..
PPM - Passivt Placerande för Många : En analytisk studie av premiepensionsspararnas avsaknad av strategier för fondval
Introduction: In 1998, the pension system was changed and the so called PPM system was introduced. The PPM system is partly fund-based, partly distribution-based. There are approximately 700 different investment funds to choose between, at a maximum five for each individual. For persons who are not familiar with the financial market, the choice might be difficult. The lions? part of the investors do not seem to have an active strategy.
Optimering av biologisk fosfor och kvävereduktion i ett reningsverk för hushållsspillvatten
In connection with Henriksdals wastewater treatment plant (WWTP) a smaller plant is situated called Sjöstadsverket where new methods for wastewater treatment are tested and evaluated in different process lines. On one of the lines experiments with enhanced biological phosphorous removal (EBPR), have been carried out to evaluate if it is a good alternative to traditional chemical phosphorus removal. This thesis evaluates the results from the experiments conducted during fall 2005.The incoming water from Hammarby Sjöstad consists of only household wastewater, which gives a wastewater with high concentrations of nutrients and organic carbon. This is partly positive, because one of the limiting factors for effective biological phosphorus removal is the lack of easily biodegradable organic carbon. The high concentrations of ammonium and phosphorus demand a high reduction to achieve the requirements of outgoing concentration.To optimize the process experiments with different recirculations and different aeration techniques have been made.
Utvärderande bibliometri: en jämförelse mellan två kvalitetsindikatorer
This master's thesis aims to explore the field of evaluative bibliometrics. In short, this field of research uses bibliometrics - i.e. the application of mathematical and statistical methods to books and other media of communication - as a research assessment tool. In recent years, evaluative bibliometrics has been an increasingly used method in research evaluation and is today used and implemented in many countries worldwide. Today, in Sweden, we can also see that evaluative bibliometrics is highly recognised and, in some cases, used in practice.
Två sidor av samma mynt : En studie om mötet inom ekonomiskt bistånd
The overarching aim of this paper is to study the professional encounter in its complexity. The requirements for receiving welfare is set by the professional and it's the professionals decision if they are met in the proper manner. This makes the assessment of the clients conditions and the correctness of the assessment hence important. There are several levels which is necessary for the social worker to take into consideration.We have therefore made a socio-analysis by using a theoretical model of Johansson (2006) where he uses the Social Psychology of the encounter to create a model with four levels, which is always present in the professional encounter: structural, positional, relational, and experience level. Our base was that the one responsible for handling these levels was the professional which led us to search for literature concerning the professional approach.Our study is formed as a qualitative case-study. Our empirical data consist of qualitative interviews with four social workers handling social allowance.The results shows that the complexity of the professional encounter requires a professional approach.
Lärare om bedömning och betygssättning : Hur ser bedömningen och betygssättningen ut på olika skolor och hur likvärdig är den?
This essay examines how high school teachers in physical education and health thinks about assessment and grading. The essay show how teachers assess pupils during lessons and how teachers grade their students. The survey was based on interviews, in which six different teachers answered questions on the topic of assessment and grading. The issues surrounding assessment was linked to the theoretical concepts of formative and summative assessment, to see if the assessment methods teachers use. The issues surrounding grading was related to the theoretical concepts of validity and reliability in order to see how similar the grading is.The essay provides a picture of how the assessment and rate again looks different teachers.
En granskning av det internationellt använda frågeformuläret International Outcome Inventory for Hearing Aids (IOI-HA).
Assessment of hearing aids can be done by inventories. The result of the inventories can show the patients need and how the hearing aids works in the patients daily life. The result of the inventories can be influenced by the difference in languages and the cultures. The inventory IOI-HA should not be sensitive to those factors.The aim of this study was to compare and analyse material, method and to report and analyse the result from a pilot study made at Sahlgrenska University.The result showed that IOI-HA is a natural inventory which is able to be used internationally. The four studies in England, USA, the Netherlands, and Germany showed that the psychometric properties are similar across languages and cultures.
Grundvattensänkning till följd av järnvägstunnel genom Hallandsås : miljökonsekvenser relaterade till förändrad kväveomsättning i mark
This thesis was carried out to give some background information to a report of SLU (Swedish University of Agricultural Sciences) for the Swedish National Rail Administration (Banverket). The requested information was to provide basic data for an environmental impact assessment of the construction of the tunnel through Hallandsås. The aim with the thesis work was to discuss and quantify the leaching of nitrate and the emission of nitrous oxide from the soil at the groundwater level established through the tunnel project. The nitrogen related processes that could be affected were described and discussed. The different areas where a decreased groundwater level can cause changes in the nitrogen processes are the wet and moist areas.
Nötköttsproduktion : -En jämförelse av djurskyddslagstiftning, är svensklagstiftning mer optimal för djurvälfärden?
Sweden?s animal legislation was adopted in 1988 and is one of the most rigorous legislations in the world. Despite this, Sweden import beef from countries where animal legislation is not in accordance to the Swedish legislation. The meat consumption in Sweden has, just like the importation of beef, increased while Sweden?s own beef production has decreased.
Epiphytic lichens associated with different traffic intensities along the highway E4
Inventories of epiphytic lichens on Scots pine (Pinus sylvestris) were conducted at three sites in east central Sweden: along the newly build motorway (Road E4), along the old road (Road 600) and in a reference site, to compare the effects of traffic pollution on lichen diversities. At each site, species richness, lichen mean sensitivity value (MK), air quality index of the forest stand/sample plot (LKI) and nitrogen impact value (N) were calculated and it was tested if there was any difference between the sites. Twenty-four species were observed in total, and Parmeliopsis ambigua and Hypogymnia physodes were the most common species at all sites. At Road E4, fewer lichen species were observed than at the other sites and this might be due to the impact of air pollution. The species richness at Road 600 was similar to that of the reference site, which might be explained by the improved air quality.
Hydrauliken i Ångersjöns fosforfällor : bestämning av flödesvägar och åtgärdsförslag för optimal fosforbindning vid avloppsrening med reaktiva filter
Discharge of untreated wastewater leads to unnaturally high levels of nitrogen and
phosphorus in rivers, lakes and the sea, which results in unbalanced ecosystems with
eutrophication and lack of oxygen. Part of the phosphorus in surface waters is coming from
on-site wastewater treatment from scattered households with unsatisfactory purification.
Blast furnace slag is a by-product from iron production, and has in laboratory trials showed good phosphorus binding capacity. To test blast furnace slag as a reactive filter media for phosphorus separation in a full scale experiment, a wastewater treatment plant has been built behind the picnic area at Ångersjön alongside the road E4 in central-eastern Sweden. The plant contains two parallel lines, one with blast furnaces slag and the other with Filtralite-P as phosphorus sorbent. Both filters have showed decreasing phosphorus purification effect with time in spite of a low wastewater load.
