Using SBAR to Decrease Transfers from the Long-term Care to the Emergency Room

Bowers Garrett, Phyllis Marie 01 January 2016 (has links)
Care of the elderly, long-term care resident in the emergency department is an issue of importance because of the overall impact on healthcare costs, potential for negative outcomes for the resident, and the loss of revenue. The purpose of this project was to decrease avoidable transfer of residents to the Emergency Department. Using the Antecedent, Target, Measurement logic model, poor quality assessment data was deemed the antecedent of the avoidable transfer. The goal of the project was the implementation of a standardized process of assessment that would have decreased avoidable transfer of the resident. The project would have involved training of the nursing staff in the use of the Situation Background Assessment and Recommendation tool for collecting and communicating pertinent data. The tool would have been completed at each acute complaint and would have indicated disposition. Data would have been collected by the Education Coordinator and organized for review and comparison with preintervention data. Social change implications would have included enhanced communication, potential for increased nurse and physician satisfaction which could have potentially increased job satisfaction, and improved recruitment and retention. Autonomy and self-pertinence empowers the nurse to be a stronger advocate. Positive outcomes increase when care is provided by those familiar with the patient norms and the setting. Financial savings can have an impact on the cost of healthcare. This project would also have allowed for and encouraged internal review of process and practices. This project was not implemented and so remains inconclusive.

Does Size Matter? : Abnormal Returns and Market Efficiency at Stockholm Stock Exchange

Einarsson, Per, Wännerdahl, Hampus January 2008 (has links)
Background and purpose In Sweden private savings in stocks has experienced a large increase and in year 2006 there were 6.7 million people, or 77 per cent of the population owning stocks. A recent study shows that more than every other Swede has deficient knowledge in trading with stocks. Since small private investors often do not know how to gather and interpret information they must utilize investment advices. The large increase in private savings in stocks, the lack of investment knowledge together with the large increase in Internet usage has resulted in investment advice seeking on the Internet. One of the largest sources of investment advices on the Internet in Sweden today is Avanza.se. The purpose with our thesis is to describe and analyze if, after a buy recommendation issued at Avanza’s website, the effects with respect to abnormal return and market efficiency differ significantly depending on a company’s capitalization value. Method We have used a quantitative approach to fulfill our purpose. The secondary data required to do so was gathered from the OMX-Group’s website, where historical prices and Index information was collected, and from the online broker Avanza’s website where the buy recommendations were compiled. In order to conduct statistical tests and calculations we have used the statistical software SPSS. Frame of Reference The theories we made use of mainly treated market efficiency and abnormal return. Conclusions We have seen that the recommendations’ effect concerning abnormal return differ signifi-cantly depending on capitalization value, where the effect on companies with smaller capitalization values are larger. We have also found tendencies of market inefficiency at the semi strong level for stocks with smaller capitalization value.

Model for End of Life Treatment of Polymer Composite Materials

Hedlund-Åström, Anna January 2005 (has links)
Because of increasing environmental demands, especially on dealing with products end of life phase, product manufacturers and designers must consider the future disposal of their products. For conventional materials like steel and aluminium well-functioning recycling methods exists. This is not the case for structures of polymer composites, which are used more extensively, especially for structures like vehicles and vessels. Several techniques do exist but they are not yet commercially available. The current disposal methods of polymer composites are landfill and incineration. Polymer composites are materials, which consist of several materials like fibre, matrix, and additives. In the form of sandwich constructions also foam core material is added. This circumstance complicates the waste treatment of composite materials. In this thesis a model for assessing possible future waste treatment techniques for polymer composites including sandwich structures is presented. The model is meant to be used as an aid for preparing future disposal for end of life products for planning waste treatment and for facilitating communication in contacts with waste receivers. Recommendations for waste treatment have been formed for a number of polymer composites. These recommendations are based on the analysis of costs and environmental effects and they compare different scenarios for mechanical material recycling and energy recovery by waste incineration. The result of this study points out material recycling as the preferable method for the main part of the studied materials. But this recommendation is strongly dependent on type of virgin material replaced by the recycled material. Energy recovery can also be considered if the polymer composite waste replaces coal, which is non renewable. Though incineration will always result in a cost for the waste producer. In the recommendations mentioned above no information concerning implementation of the different waste disposal techniques is included. Therefore, in this study a model for assessing possible waste disposal techniques for polymer composites is presented. The model is based on internal factors, which are related to the waste and to the processes. To implement the model relevant waste properties must be identified in order to fulfil the conditions set by the required processes involved. A case study was carried out using the proposed model for assessing different waste disposal techniques for the hull of the Visby Class Corvette in the Royal Swedish Navy. Six different techniques were studied for the hull structure. Since almost all the important waste properties were known and the waste was assessed to be treatable all the included techniques except one are shown to be usable in the future. Many investigations have pointed out material recycling as the best alternative considering environmental effects. This is also valid for polymer composite materials. Since recycling polymer composites is a complicated process, especially recycling thermoset composite it is important to aquire comprehensive information about the constituents of these materials. / QC 20101021

An analysis of the management and economics of salmon aquaculture

Liu, Yajie 05 1900 (has links)
Salmon aquaculture can be a potential solution to bridge the gap between declining capture fisheries and increasing seafood demand. However, the environmental impacts it creates have generated criticism. The overall objectives of this dissertation are to examine the economic consequences of environmental issues associated with salmon aquaculture, and to explore policy implications and recommendations for reducing environmental impacts. These objectives are addressed in five main analyses. The growth of salmon aquaculture is analyzed based on farmed salmon production in the four leading producing countries and the sector as a whole. Analyses indicate that salmon aquaculture is unlikely to continue to grow at its current pace. A joint production function approach is used to estimate pollution abatement costs for the salmon aquaculture industry. Results reveal that pollution abatement costs vary among observations and models. On average, pollution abatement cost is estimated at 3.5% in terms of total farmed salmon production, and 6.5% in terms of total revenue of farmed salmon. The ecological and economic impacts of sea lice from salmon farms on wild salmon population and fisheries are also studied. Analyses suggest that these effects are minor when the sea lice induced mortality rate is below 20%, while they can be severe if the mortality is greater than 30%. Sea lice have greater ecological and economic impacts on pink salmon than on chum salmon. These effects are greater under a fixed exploitation rate than under a target escapement policy. The economic performance of open netcage and sea-bag production systems for salmon aquaculture is compared. Netcage systems appear to be more economically profitable than sea-bag systems when environmental costs are either not or only partially included. Sea-bag systems can be financially profitable only when the salmon they produce can achieve a price premium. Finally, policy implications are explored and recommendations are made for sustaining salmon aquaculture in a holistic manner based on the results from previous chapters. Technologies, economic-based instruments and more stringent environmental policies can be employed to reduce environmental impacts. However, there is no single solution to solve these environmental impacts, and a combination of policy options is needed.

Hiv-positiva kvinnor och deras barn : PM granskning från samtliga Svenska förlossningskliniker

Wallgren, Kim, Ström, Frida January 2013 (has links)
Under år 2011 levde ca 5800 personer i Sverige med diagnosen hiv (humant immunbristvirus) och 18 nya fall upptäcktes via MHV:s screening av gravida kvinnor. Risken att ett barn smittas under graviditet och förlossning är 15-25 % om kvinnan inte behandlas med antiretrovirala läkemedel. Riskerna ökar med ytterligare 10-15 % om kvinnan sedan väljer att amma sitt barn. Barn till kvinnor som behandlas med antiretrovirala läkemedel och har icke mätbara virusnivåer i blodet löper en risk på 0,4-1 % att smittas. RAV (referensgruppen för antivirala medel) uppdaterade 2010 sina behandlingsrekommendationer för hiv-1 positiva kvinnor under graviditet och förlossning. Detta till följd av att WHO ändrade sina riktlinjer samma år. En stor skillnad i rekommendationerna är att kvinnan får möjlighet till en vaginal förlossning om virusmängden och den obstetriska anamnesen tillåter. Syftet med studien var att granska PM för handhavandet av den hiv-1 positiva kvinnan och hennes barn under förlossning och puerperium på förlossningskliniker i Sverige. En kartläggningsstudie valdes med beskrivande och jämförande design. Metoden var att samla in samtliga förlossningsklinikers PM och/eller strategi för omhändertagande av patientgruppen. De insamlade PM:en granskades enligt RAV:s behandlingsrekommendationer och enligt AGREE som är ett validitetssäkrat instrument för granskning av kliniska riktlinjer. Resultatet visar på stor variation i både uppbyggnad av PM och följsamhet till behandlingsrekommendationer. Förlossningsklinikernas behandlingsstrategier skiljer sig också åt beroende på antal förlossningar/år och huruvida de tog emot eller skickade vidare patientgruppen. Vissa förlossningskliniker saknade helt PM och några av dessa tog ändå emot patientgruppen. Generellt sett var PM:ens utformning undermålig gällande uppbyggnad och uppdatering, samt att flera förlossningskliniker ej hade anammat de nya behandlingsrekommendationerna från RAV. / In 2011, approximately 5800 people in Sweden were living with an hiv (human immunodeficiency virus) diagnosis and 18 new cases were detected during antenatal screenings of pregnant women. The risk of a child being infected during pregnancy and delivery is 15-25 % if the woman hasn’t been treated with antiretroviral drugs. The risk will increase a further 10-15 % if the woman choses to breastfeed the child. The children of women that are treated with antiretroviral drugs and has non-measureable levels of virus in the blood runs a risk of 0.4-1 % of being infected. In consequence of WHO changing their guidelines in 2010, RAV (a reference group for antiviral treatment) updated their treatment recommendations for hiv-1 positive women during pregnancy and delivery. A major difference in the recommendation is that the woman is given an option of vaginal delivery, if allowed by the viral levels and obstetrical history.The purpose of this study was to review PM for the handling of the hiv-1 positive woman and her child during delivery and puerperium on maternity clinics in Sweden. A survey study was chosen with descriptive and comparative design. The method was to gather PM and/or strategy for care of the patient group from all clinics. The gathered PMs were reviewed according to RAV’s treatment recommendations and according to AGREE, an instrument for examination of clinical guidelines. The result displayed a great variation in both PM structure and adherence to the treatment recommendations. The care strategy of a maternity clinic was dependent of deliveries per year and also whether the patient group was admitted or referred. Some maternity clinics lacked PMs entirely and some of these would nevertheless admit the patient group. In general, the form of the PMs were substandard regarding structure and maintenance and several of the maternity clinics had not embraced the new treatment recommendations from RAV.

Aktierekommendationer : En jämförelse av aktierekommendationer mellan banker och affärstidningar / Stock Recommendations : A comparison of stock recommendations between Banks and Business Magazines

Farag, Lawan, Kalkan, Kemal January 2012 (has links)
Bakgrund: Det har i tidigare forskningar bevisats att privatpersoner har en tendens att vilja få hög avkastning på kort tid och därför väljer de ofta att investera i aktier. Detta leder till att aktierekommendationer har en stor påverkan på de privatpersoner som vill investera i aktier utan att ha en god kunskap inom ämnet. Det har även visats i olika undersökningar att privatpersoner i majoritet har lägre tillit för affärstidningar än för banker. Syfte: Syftet med denna undersökning är att undersöka banker och affärstidningarnas utfall av aktierekommendationer på den svenska aktiemarknaden. Genomförande: En kvantitativ undersökning genomfördes, där vi valde fyra olika banker och fyra olika affärstidningar. Tidsperioden var tre år, mellan 2010-01-01 och 2012-12-31. Totalt undersöktes 617 köp- och säljrekommendationer under fyra olika perioder; en dag, fem dagar, tio dagar och 30 dagar efter publiceringsdatumet. Resultat: Resultatet av undersökningen antyder på att det finns en skillnad mellan banker och affärstidningar gällande träffsäkerheten på dess publicerade aktierekommendationer. Affärstidningarna har högre antal träffar än bankerna, både när det gäller säljrekommendationer och köprekommendationer. / Background: It has been shown in previous researches that individuals have a tendency to want to get high returns in a short time and therefore often choose to invest in stocks. Stock recommendations have therefore a large impact on the individuals who want to invest in stocks without having good knowledge of the subject. It has also been shown in various studies that the majority of individuals have lower trust in business magazines than for banks. Purpose: The purpose of this study is to investigate the banks and the business magazines outcome of the stock recommendations of the Swedish stock market. Method: A quantitative study was conducted, in which we chose four different banks and four different business magazines. The time period was three years, between 2010-01-01 and 2012-12-31. A total of 617 stock recommendations were investigated during four different periods; one day, five days, ten days and 30 days after the date of publication. Conclusion: The study results indicate that there is a difference between banks and business magazines regarding the accuracy of the published stock recommendations. Business magazines have a higher number of hits than the banks, both in terms of sales recommendations and purchase recommendations.

Mediabevakning och aktiemarknadens reaktion på ny information

Serifler, Levent, Lundborg, Rasmus January 2012 (has links)
Relationen mellan publik media och kapitalmarknader är ett område som studerats under en lång period. Åsikter har väckts om att massmedia är en viktig faktor vid förståelsen av finansiella marknader då media har förmågan att ge upphov till irrationella reaktioner. Utifrån detta har en kritik mot massmedia växt fram som menar att media inte förmedlar viktig information. En del studier visar emellertid att en lättare åtkomst till ny information leder till att priser på finansiella marknader kan justeras mer effektivt.Syftet med denna studie är att förklara hur den historiska mediabevakningen som föregår en aktierekommendation påverkar hela aktiemarknadens aktörer genom att studera den överavkastning som föregår och efterföljer rekommendationen ifråga. Undersökningen har baserats på rekommendationer gällande svenska aktier som är börsnoterade på Large-, Mid- och Small-Cap listorna på Nasdaq OMX Nordic Stockholm under en period som sträcker sig över två år. Underlaget för mediabevakning utgår ifrån artiklar ur stora svenska tidsskrifter och rekommendationerna är hämtade ifrån större analytikerhus.Tidigare forskning har gjorts på aktiemarknadens reaktion vid publicerandet av nya rekommendationer men denna studie tar hänsyn till ytterligare en variabel, antalet historiska publikationer i media, för att försöka skapa ytterligare förståelse på området.Resultatet antyder att den grad av mediabevakning som föregår publicerandet av en aktierekommendation inte har en påverkan på marknadens mottagning av den nya informationen. Den tydligaste skillnaden som kunde ses mellan rekommendationer som föregicks av en hög respektive låg mediabevakning var att rekommendationen som föregicks av en låg mediabevakning visade ett marginellt större utslag vid publikationsdagen. Då denna observation emellertid inte kunde säkerställas statistiskt går det inte att dra några slutsatser utifrån detta resultat och studien kan således inte påvisa att mer lättillgänglig information leder till en mer informerad marknad. / The relationship between public media and capital markets is a subject that has been studied for a long time. Some argue that mass media is an important factor in understanding the financial markets because the media has the ability to generate irrational reactions. On this basis a critique against the media has emerged which believe that the mass media does not publish valuable information. Some studies, however, have concluded that an easier access to new information leads to more efficient price adjustments within the financial markets.The purpose of this study is to explain how the historical media coverage preceding stock recommendations affects the entire stock market by studying the abnormal return that precede and follow the studied recommendations. The study is based on recommendations on Swedish shares listed on the Large-, Mid- and Small-Cap lists on the Nasdaq OMX Stockholm during a period of two years. Media coverage is based on articles from major Swedish magazines while stock recommendations are obtained from major analysts.Previous research has been done on the stock market's reaction to the publication of new recommendations, but this study takes an additional variable into account, the number of historical publications in the media, in an attempt to create further understanding in the field of subject.The results suggest that the degree of media coverage preceding the publication of a stock recommendation do not have an impact on the market's reception of the new information. The most noticeable difference between the recommendations that were preceded by high and low media coverage respectively was that the recommendation which was preceded by low media coverage showed a marginally larger abnormal return at the publication date. Since this observation, however, could not be confirmed statistically the study cannot draw any conclusions from this result and thus the study cannot prove that a larger amount of easily accessible information leads to a more informed market.

Barns eget perspektiv på ”bra” mat : en kvalitativ studie med elever i årskurs tre / Youth's own perspectives on "Good" food : A qualitative study of students in grades three

Badla Nilsson, Leila January 2011 (has links)
This exam is about student’s perception of food and dietary advice. I illustrate food and eating from the youth's own perspective. The aim is to investigate how students perceive as "good" diet. It also reveals that students at the surveyed schools have poor knowledge of what is plate model. In the Swedish curriculum Lgr11 it is clear that the core content for students in grades 1-6 will contain the student include being informed about the selection and use of goods used in the home and how they in turn affect health (National Agency for Education, Lgr11: 43). I have interviewed students in grades 3 through focus groups to make it clear to you as readers to understand their own knowledge about nutrition.
