Vad finns det för värden i matematikböcker? : En analys av värden förmedlade i läromedel för gymnasieskolans kurs i matematik A

I denna uppsats studeras förekomsten av värden i geometrikapitel i läromedel för gymnasieskolans Matematik A. En metod baserad på innehållsanalys som använts i en tidigare studie om förekomst av värden i algebrakapitel har vidareutvecklats. Sammanlagt 955 uppgifter i geometrikapitlen i fem olika läroböcker har analyserats. Resultatet visar på en skillnad mellan intentionerna i gymnasieskolans styrdokument och det utrymme olika värden ges. Även skillnader mellan det utrymme studerade läromedel ger åt olika värden har påvisats..

Kvällens sista beställning: från Kungsgatan till akuten : En studie om effekten av Ansvarsfull alkoholservering på krogvåldet i centrala Karlstad

This thesis represents my individual final research in Societal Risk Management. The aim of the study is to research whether the method called Responsible Beverage Serving has had the desired effect of diminished alcohol-related violence in Karlstad City, after its implementation into the ordinary operational agenda for Karlstad district in the county of Wermland. According to the method, the alcohol-related damages as well as alcohol-related violence in a society can be reduced by refusing to serve minors and clients who are excessively intoxicated.In order to be able to reach the aim of the thesis, the subsequent questions must be answered;Has excessive drinking reduced in the bars and clubs in Karlstad City?Has it become more difficult for minors to be served alcohol in the bars and clubs in Karlstad City?Has the police reported amount of assaults outdoors diminished regarding the alcohol-related violence in Karlstad City?This research is an intervention study and uses a quasi-experimental design. The intervention itself is the method called Responsible Beverage Serving.

Effektivisering av urvalsprocesser vid analysering av björnspillning : Ett förslag till den svenska förvaltningen av brunbjörn Ursus arctos

The aim with this report is to formulate a strategic method to optimize selection processes of DNA-samples from a faeces inventory to identify as many individuals in as few analyzes as possible, and by that keep down the costs of brown bear management. Brown bear management in Sweden founds today on results from faeces inventory and is substantially led by the county administration boards. Data from the years of 2004 and 2009´s inventories in Västerbotten was used to test and evaluate different methods in selection processes of which faeces that should be sampled. Comparison were made between making selection by chance, by spatial distribution and by calculating variations in logistic regressions coefficient b, in other words bear density and probability in finding same individual in several faeces. We can show making selection by chance is the most uncertain method.

Laborativ matematik : Är det ett gynnsamt arbetssätt i matematikundervisningen?

Att eleverna i skolan ska utvecklas och nå de mål och kunskapskrav som finns skrivna i läroplanen är en central del i skolvärlden. Men hur når man då dessa på bästa sätt? Hur ska man som lärare veta vilken undervisning som är bäst för sina elever? I läroplanen står att eleverna ska ges en varierad undervisning där eleverna själva ska få gestalta, prova och utforska (Lgr11). Syftet med denna litteraturstudie är att undersöka om laborativa arbetsätt i matematik är gynnsamt för eleverna. I studien framställs att arbeta laborativt kan vara gynnsamt men till en viss del och att det beror på en del olika faktorer, som exempelvis lärarens roll och hur väl uppgiften och materialet framträder varandra..

NUDGING Kan nudging leda oss till att äta mer klimatsmart - Ett empiriskt experiment på IKEA med syfte att få restauranggästerna att äta mer vegetariskt

Food consumption generates externalities such as carbon dioxide emissions, which contribute to global warming. The principal issue is that emissions are not covered by the "polluter pays principle". For this reason, new policy instruments need to be tested and implemented to correct the externalities. In food production, beef and dairy production has the largest environmental impact in terms of carbon emissions. As food is a necessity, simply reducing production will not solve the problem.

Risk för bostadsägare - en analys av risken vid förändringar av ränta och elpris

Since 1996 the Swedish households have ten folded their volume of loans for own homes that is attached to a floating interest rate. Also in 1996 the Swedish electric market was deregulated. These two facts have increased the volatility in the household expenses for these two commodities. This thesis studies the risk for homeowners attached to the exposure against the electric and the credit market. The risk model used is Cost-at-Risk which is usually used by public authorities for analysing the risk involved with national debt.

Utvärdering av Sensus amningsutbildning för blivande föräldrar

ABSTRACTStatistics show that breastfeeding prevalence for Sweden has fallen since the mid 90´s. Studies show that breastfeeding offers health benefits to both mother and child and that the mothers' belief and confidence in their ability to breastfeed is a key factor to having a positive breastfeeding outcome. In 2010, Amningshjälpen in collaboration with Sensus studieförbund, started a nursing course, for mothers-to-be, who wished to breastfeed their babies and its aim was to prepare them for a successful and enjoyable experience.Objective: To examine whether a preparatory breastfeeding course can affect mothers' confidence in their ability to breastfeed and if that ability can affect the breastfeeding outcome when the child reaches four months. A further aim is to investigate the experience of  perceived problems surrounding breastfeeding and what affect these might have on the mothers' confidence in breastfeeding when the child reaches four months.Design/Methods: A quantitative approach with prospective experimental design was used to evaluate the study. The questionnaire Breastfeeding Self-Efficacy Scale Short Form (BSES-SF) was used three times to measure women's trust in lactation.

Utvecklingen av dödsfall till följd av oavsiktlig skada i länder under snabb ekonomisk utveckling

Purpose.The purpose of this essay was formulated as to examine the relationship between the development of deaths caused by unintentional injury and fast economic development in a country. The purpose is to create a picture of the development in the chosen countries.Background.Injuries and the deaths that sometimes follow are a problem for all communities, if nothing else just because of costs and the absence of incomes for the state. Countries ability to restrain these deaths should be of interest. Studies show that the number of deaths causedby unintentional injuries correlates inversely with the GDP/c, we can therefore expect that better economic conditions leads to fewer deaths and vice versa. It has been shown that an economic crisis often leads to considerably higher death rates.

Simulering som utbildningsverktyg

Simulatorer används för utbildning, forskning och utveckling och det område där simulering troligen haft störst betydelse i modern tid är flygutbildning. En simulator är kostnadseffektiv och utsätter inte eleven för de risker som är förknippat med flygning och kan helt eller delvis ersätta utbildning på verkliga flygplan. Hur mycket flygtid som en simulatorutbildning kan ersätta är beroende av simulatorns realism. Syftet med studien var att fördjupa sig i simulering som utbildningsverktyg samt kartlägga användandet av flygsimulatorer vid flygskolor och simulatorinstruktörernas uppfattning om realism i simuleringen. Med kartläggningen kan man bilda sig en uppfattning hur utveckling i informatik i form av förbättrad realism och val av lämplig nivå av realism har bidragit till dagens pilotutbildning i Sverige.

Vaccinering mot H1N1 : En studie av vad som påverkade svenska individers vaccinationsbeslut 2009

The Swine flu (H1N1) erupted in 2009 and wasquickly spread over the world and developed into a pandemic, with a great threat against people?s health. It was soon discovered that the H1N1?virus had a different character than the seasonal flu, since it especially affected younger individuals and the consequences from the disease were expected to be more severe. In Sweden it was decided to provide a free of charge vaccination against the H1N1-virus, and the Swedish vaccination ratiobecome relatively high compared to other countries.

Pedagogers integrering av matematik i tematiskt arbete

Hur upplever och integrerar pedagoger, i grundskolan, matematik i tematiskt arbete. För att undersöka detta genomfördes åtta intervjuer med pedagoger, på skolor i Sverige, som profilerar sig med tematiskt arbete på deras hemsida. Metoden som valdes för att genomföra undersökningen var kvalitativa intervjuer. Resultatet visade att matematik är det ämne som pedagoger är sämst på att integrera. Det visades sig även att pedagoger upplever matematik som det svåraste ämne att integrera i sin tematiska undervisning, vilket även forskning visat..

En studie av lösensdagseffekt på aktiekursens volatilitet

The purpose of this study is to examine the expiration day effect on a stocks volatility due to stock option expiration, which is every third Friday in the month on Stockholm stock exchange. Volatility is the standard deviation of a stock. It measures the uncertainty about a stocks future movement. When volatility increases, the chance or probability of a stock going up or down increases. It?s a common rumor among stock traders that stock volatility tends to increase nearby expiration day.

Underifrånperspektiv - en analys av utvärderingen av demokrati och delaktighetsmålet i storstadssatsningen i Malmö

The Swedish metropolitan politics have had the bottom-up perspective as a major principle to evolve the democratic participation in segregated areas. My objective was to investigate if a bottom-up perspective has been used as a method of evaluation in a sample of 10 evaluation reports made about democratic participation in Malmö.The key questions were; In the evaluations:- How was the bottom-up perspective and related concepts defined?- What criterias and theories were used?- What values surfaced?- What methods were used?- Has a critical approach been used?The method used is analysis using the theories of Critical Social Method by Alvesson & Deetz, Values in evaluation by House & Howe and Choices of perspective by Eliasson.None of the analysed evaluations have used participatorial methods. As participation is defined mainly statistically, the criterias are usually quantitative measurements, though the evaluators agree that democracy is a matter of quality. There is a common lack of theoretical basis of analysis and methodology description.

El Niño Southern Oscillation och dess atmosfäriska fjärrpåverkan.

This paper is a literature study aiming to describe scientists newest theories andknowledge concerning the El Niño and Southern Oscillation. Firstly I have described the?normal? conditions with rising and sinking air in Hadley- and Walker-cells in theequatorial Pacific and from there moved on to explaining the reversed circulation patternsand higher sea surface temperatures (SST) leading to rising air and anomalousprecipitation in eastern Pacific constituting the El Niño phenomenon. My outermostinterest regarding El Niño has been the associated teleconnections, especially in nontropicalareas. I have described the El Niño effect on the Indian summer monsoon, ontropical cyclones and on storms and precipitation on higher latitudes.

"Att ha matematik" - ett begränsat fenomen : En fenomenografisk studie av elevers uppfattningar om vad det innebär att ha matematik

Syftet med min studie är att belysa elevers uppfattningar om vad det innebär att ha matematik. Delar av studien ägnas åt att lyfta fram uppfattningar som elever i behov av särskilt stöd, d.v.s. elever med åtgärdsprogram, har. Åtta elever intervjuades i en fenomenografisk studie om vad de lägger i begreppet "att ha matematik".Studien visar att det finns en uppfattning att det individuella arbetet är grunden för att ha matematik och att kommunikation mellan elever ses som ett avsteg från matematiken. Det kvantitativa formella matematikarbetet med läroboken betonas av eleverna.Men samtidigt finns också en uppfattning att matematik kan has i samlärande.
