Lillån : Statusbedömning enligt EU:s ramdirektiv för vatten
In Sweden, the County Administration board is responsible for improving the water quality in lakes and watercourses according to the European Union Water Framework Directive. In Västmanland county, where river Lillån is situated, the County Administration of Västmanland have the main responsibility for the aquatic environment in that area. The knowledge about the different watercourses in the chatchment of river Lillån is today limited. The aim with this study was to evaluate the ecological quality of River Lillån based on water chemistry analyses and benthic fauna investigations. The aim was also for the benthic fauna to compere different samplingsites and sampling methods with each other in order to see how the species composition changes in the river, and to see the advantages and disadvantages with different sampling tecniques.
Formativ bedömning och individanpassad undervisning i matematik. En inblick i hur dessa metoder ter sig i grundskolan.
Syftet med arbetet är att undersöka hur lärare resonerar kring hur de arbetar med formativ bedömning och individanpassad undervisning i matematikundervisningen i grundskolan. Vi har därför undersökt detta område närmare genom en empirisk enkätstudie. Vårt urval har bestått av respondenter som dagligen möter denna problematik och som har erfarenheter inom området d.v.s. grundskollärare.
Hälften av respondenterna hävdade att de individanpassade matematikundervisningen i stor utsträckning, resterande i måttlig eller liten utsträckning. Gällande frågan om formativ bedömning svarade omkring hälften av respondenterna att implementeringen av formativ bedömning sker i stor utsträckning och resterande i liten eller måttlig utsträckning.
Risk Management : Revisionsbyråernas arbete med att hantera risker vid klientaccepterande
SAMMANFATTNINGGenom de skandaler som revisionsbranschen mött har ökande krav på branschen uppkommit. Det kan finnas risker i dagens samhälle som inte existerat eller varit aktuella tidigare men på grund av de förändringar som skett i samhället nu framträtt. Vi ville studera hur revisionsbyråerna förhåller sig till dessa samt hur de finner en väg att hantera dem. Studiens syfte var undersöka om det finns något aktivt arbete med att hantera de risker som är förknippade med accepterandet av klienter, det lyder:Syftet med vår uppsats är att studera om det finns ett aktiv arbete med Risk Management på revisionsbyråerna samt i så fall hur detta går till och vilka risker som de då främst vill undvika vid accepterande av klienter. Vi vill även studera hur revisionsbyråerna hanterar de risker som de väljer att acceptera.Då vi hade uppfattningen att det är ohållbart för revisionsbyråerna att inte på något vis hantera de risker de ställs inför föll det sig troligt för oss at de större byråerna aktivt arbetar med Risk Management.
Miljömärkningar och medvetenhet : En studie om unga vuxnas medvetenhet kring miljömärkningar
Dagens samhälle är präglat av materialism och dagens konsumtionsmönster är ohållbara ur miljömässig synpunkt. Konsumtionen skapar därmed miljöproblem och ett viktigt styrmedel för att göra den mer hållbar är miljömärkning. Miljömärkta produkter produceras på ett miljöansvarigt sätt utan kemiska bekämpningsmedel och gödsel som är skadliga för både människa och miljö. Syftet med denna studie var att undersöka den nuvarande medvetenheten kring miljömärkningar hos unga vuxna på Möckelngymnasiet. Metoden för studien var enkätutdelning till skolklasser som går sista året på gymnasiet.
Planering och gestaltning för träning och motion
Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.
Samband mellan anknytning och självkänsla hos ungdomar. En pilotstudie
Background:When the patient is critically ill the family is in a vulnerable position. The nurse's role is to support and help the family to find meaning in the difficult situation and to provide realistic hope. Balancing between the patient's and the family's needs is difficult. Knowledge about how nurses experience difficulties in the interaction with family is required in order to grant good care too critically ill patients and their family-members.Aim:To describe nurses' perceived difficulties in the interaction with family-members of critically ill patients.Method:The study is a qualitative literature-based study based on qualitative research. Results: The analysis resulted in four main themes; difficult disunion, environmental constraints, interpersonal difficulties and communicative difficulties.
Finansiell risk och lönsamhet i Svenska fastighetsbolag under 2008
Syfte: Studiens syfte är att analysera och undersöka om det finns något samband mellan den finansiella risken och lönsamheten. Det övergripande syftet är att se om valet av finansiell risk fungerar som finansieringsstrategi i verkligheten.Metod: Studien bygger på den deduktiva ansatsen där teorier kommer att testas och analyseras mot empiriska data tagna från årsredovisningar. Den kvantitativa metoden används då data från 305 stycken årsredovisningar ska användas för att finna om det finns samband och variation mellan finansiell risk och lönsamhet definierad som vinstmarginal, Rt och Re. Årsredovisningarna utgörs av sekundärdata som samlats in från databasen Retriever. De statistiska metoder som används är bland annat medelvärde, standardavvikelse, regressions- och korrelationsanalys, hypotesprövning och t-test.Resultat och slutsats: Såväl korrelation- och regressionsanalys som hypotesprövning och t-test visar att det finns samband mellan finansiell risk och lönsamhet definierad som Re.
Mjölkureahalten som mått på vom-mikrobernas kväveförsörjning och kons miljöbelastning
The aim of this literature study was to analyze how milk urea concentration is working as a measure of the nitrogen supply to rumen microbes and indicator of the environmental load. Questions included in this literature study were how to improve the dairy cattle nitrogen efficiency and what correlations there are between milk urea, nitrogen efficiency and crude protein content in the feed. Effects on the reproduction from high ration protein content are also addressed. Dairy cattle are today fed with large proportions of protein which could lead to high expenditure of feed and environmental pollutions. The nitrogen can be lost to the environment by different pathways; leaching, denitrification or by emission to the air.

Metoder för prediktion av kardiovaskulär sjukdom med njurfunktionen
This study examines if the prediction of cardiovascular disease in hypertensive patients can be improved upon when renal function and microalbuminuria are added to the classical risk factors The predictive capability of a model is measured by discrimination, calibration, reclassification and Harrell's C.The results are ambigious. In most cases, microalbuminuria should be included in the model, but the results regarding the other measures of renal function are varied. Therefore, the selection of risk factors to include in the model depends on which measure of prediction one prioritizes..
Vatten som säkerhetsfråga : Med FN:s konstruktion av vattenfrågan som utgångspunkt
ABSTRACTThe aim of this study is to analyse if the UN today constructs the water issue as a security issue and to argue about in which way the organization in that case does so alternatively why it can be said that the UN doesn?t construct the water issue as a security issue.In order to reach this purpose the following questions will be answered:?Does the UN construct the water issue as a security issue today?-If yes, in which way?-If no, why can it be said that the organisation doesn?t?The methods used are qualitative literature studies of policy documents on water from the UN. The focus is to analyze the ideas about water and to apply my theory on the concept of security, which is Barry Buzan?s framework on security, to these ideas.The main results showed that the UN strongly constructs the water issue as an environmental security issue for environments and species and in relatively strong terms also constructs it as an environmental security issue for civilisations. In rare cases the organisation constructs it as a societal security issue, but the UN doesn?t construct the water issue as a military, political or economic security issue..
Hållbar avfallshantering : Ur ett ekonomiskt- och miljöperspektiv
Economy and environment has for a long time been studied separately and seen as incompatible. With a growing society and increasing pressure on environmental issues the need of a new economy with the environment included is necessary. This study examine if European Union´s picture of the waste hierarchy match the reality. Since the purpose with the waste hierarchy is to benefit environmental and economy. A survey was made over Käppalaförbundets waste from 2013, to see where the waste falls in the waste hierarchy.

En strategisk planeringsmodell: Att införa medborgarkontor i ett folkbibliotek med hjälp av strategisk planering
This Masters thesis is concerned with the complex planning process of setting up a citizen bureau in a public library. The aim is to find out how citizen bureaux are designed and to suggest a simplified model of strategic planning. The planning process is studied from a business perspective in the library context, and this perspective is also used to study citizen bureaux and their written plans elsewhere. A combination of qualitative methods are used: observations, focus group discussions and interviews. Observations in the public library showed a great need for an environmental analysis as well as structure to the planning process.
Efficient hedging in an illiquid market
Vattenfall hedge its future electricity production in order to decrease fluctuations in theresult. Hedging can in a simplified way be described as selling the future electricity deliveriesin long-term contracts so that the future price of the delivery becomes fixed. The contractsused are electricity forwards traded at the Nordic electricity market Nord Pool. Animbalance between buyers and sellers can lead to a situation where the forward price notequals the expected spot price. The difference between the forward price and the expectedspot price is referred to as the market risk premium.
