Det stora cancerlarmet : En studie om riskrapportering i media
This essay is about the risks of reporting science through media. We have exemplified the problems with the alarm about acryl amide that came in 2002 through the diffusionist model. From the beginning it was a debate about how dangerous acryl amide is to us humans, but later on it developed to be a debate about whoever did wrong in the intermediation, because later on it came out that acryl amide maybe didn?t cause cancer at all and the scientists didn?t know how to prove if it did or didn?t. In our essay we have based our theories about how the diffiusionist model often is inadequate, with theorists as Stuart Allan, Anders Ekström and Dorothy Nelkin..
handel med utsläppsrätter : en del av lösningen på koldioxidproblematiken?
In Rio De Janeiro, 1992, was the first document signed that meant a responsibility for industrial countries to decrease their emissions, United Nations Framework Convention on Climate Change (UNFCCC). Thirteen years later was the first legal binding document signed, the Kyoto protocol, and for the first time industrial countries all over the world was bound to decrease their emissions on greenhouse gases. Within the framework of this commitment, three flexible mechanisms (Clean Development mechanism, Joint Implementation and Emission trading) were introduced with the function to reduce the economical costs of the commitment. The flexible mechanisms Emission Trading (ET) is what this report is about.The report starts with a description of carbon dioxide and it?s effect on the environment, thereafter comes a background review of the national agreements who lies as a ground to the implementation of emission trading as a management control measure in Sweden and the rest of the world.Keywords: United Framework Convention on Climate Change, Kyoto protocol, Flexible mechanisms, Emission trading, carbon dioxide .
Prevalence of subclinical mastitis and udder pathogens in small holder dairy farms in Mapepe, Batoka and Choma areas in Zambia
Subclinical mastitis (SCM) is a well-known problem in the dairy sector, where it causes severe economic losses mainly due to reduced milk production. This is a problem not only in the western world but also in developing countries. Surveys from different developing countries have shown a SCM prevalence of 52.4 ? 88.6 % at cow level and 26.7 ? 63.2 % at quarter-level. To combat mastitis is important to optimize the milk production of the cow.
Phosphorus in agricultural soils around the Baltic Sea : comparisons of different laboratory methods as indices for phosphorus leaching to waters
Eutrophication of the Baltic Sea is a serious problem. A major contributing factor is diffuse losses of phosphorus (P) from agricultural land in surrounding countries. In order to estimate P losses, environmental monitoring of small agriculture-dominated catchments is being carried out in most of these countries. Evaluation of the risk of P leaching to waters is usually based on chemical tests originally developed to quantify the amount of soil P available for plant production. The tests are performed in different ways in the different countries and a number of different extraction agents are in use.
Introduktion till Kontinuitetsperspektivet
To explore greatly varied opinion between player and reviewer, in relation to new products in ongoing digital game series, an analytic perspective is suggested, that takes the entire game series into account, instead of analyzing games (who are part of a series) as individual productions. This is explored further by introducing a model to support this perspective, based on the game theories by Katie Salen and Eric Zimmerman, as well as Gordon Calleja. This model and chosen perspective is applied against three separate cases to see whether or not it can give insight into the approach of players (of continuing game series) and the differing opinions of players and reviewers..
Simulering av översvämningar i Nedre Dalälven
Mosquitoes are found in extremely large numbers in the lower parts of the River Dalälven. In the year 2000 the mosquito nuisance was especially high, resulting in foundation of the Biological mosquito control project. Since 2001 mosquito larvae are controlled by using a biological pesticide BTI (Bacillus thuringiensis ssp israelensis). The mosquito fauna in the area is dominated by flood water mosquitoes, a group of mosquitoes that are very aggressive and form new generations of mosquitoes during every single flooding event during the summer. To be able to efficiently control the mosquitoes it is essential to know the extension and locality of the flooding.
Simulering av simulinkmodeller medExtended Kalman FilterTidsoptimering av integrering
Simulation of different systems can be done using a graphical model description of the system based on block diagrams. The simulation software Matlab/Simulink offers a lot of possibilities to describe a huge number of systems, which can be linear as well as nonlinear. The simulation using Matlab/Simulink is done by integration based on different kinds of numerical methods.When nonlinear Simulink-models are simulated, it is often interesting to apply a Kalman filter to handle the noise that may occur within the process as well as corrupting the measurement. However, application of such a filter leads to an extensive time-consumption despite using fast computers. The reason is that the existing Matlab functions are not constructed for time optimal evaluation.
Metod för användning av Geografiska Informations System vid långsiktig vägplanering : en studie genomförd på Sveaskogs marker i Norrbotten
The forest industry is one of the most important industry branches in Sweden. Since the demand of high precision wood deliveries has increased, the demand on a well constructed forest road net also has increased. A good road net gives the wood-supplier competition advantages and also increases its service level towards its customers, lumber-mills and pulp-mills. In some parts of Norrbotten, the road net is still insufficient and not yet built out enough, and that is why it is important to know how to act and where to improve the road net in these areas.
The purpose of this thesis was to create a work-model for long term road planning in areas with no road net or a not yet complete road net. The model has been created in an ArcGis environment, where a long chain of tools has been tied together with the program ?Model builder?.
Relativ deprivation och brottslighet i folkhemmets Sverige 2002-2012
There is a known link between relative deprivation and street crime among market liberal countries. Although some research has been done with cross-national data, there is none to suggest that the observed link is as valid in a country well known for its extended welfare and generous social expenditure like Sweden. The following study uses longitudinal data to see if this recognized link between relative deprivation and street crime also stands in a country with almost a century long tradition of striving for social-, economic- and cultural equality. Even though Sweden, over the last decade, has been subjected to a series of deregulations due to policy changes at national level, and with a following rise in inequality, it is still considered to be one of the most equal countries in the west. It is therefore not unlikely that the high degree of social security will reduce the negative impact of relative deprivation on social relations among its citizens, perhaps enough so that the correlation will be significantly weakened.
Energi- och exergiflöden i stålframställningsprocesser vid
SSAB Tunnplåt AB i Luleå
Energy costs are high nowadays and that is the reason why the energy consumption needs to become as small as possible in most of the companies. To accomplish the small energy usage one needs to map the energy flows, study them and monitor them. One method that can be used for this is energy balance calculation. The method gives an opportunity to separate different energy flows and see where each flow is heading. There is also another method which is more advanced than energy balance calculation.
Re-design på uppdrag av Spotify : Framtagning av designförslag för ny visningsvy för internprogram baserat på kontextuella intervjuer
Spotify is a music service that offers on-demand streaming and is available in several countries worldwide. As the company and the interest for it grows, more and more parties are involved and those involved, including the record labels want to control and get an overview of their products. They want to be able to see, for example, when a product is available on Spotify and in which countries.Spotify is in May 2013 in process of developing a to be used by administrators on Spotify in order to meet the record labels with the information requested. The new software intends being used by administrators but also by the record labels so that they will be able to overview their products availability.We were asked by one of the developers to conduct user interviews and tests to result in a design proposal on how the display page of information about a product could be visualized more clearly so that it suits both record labels and employees at Spotify. The results of our contextual interviews were translated into a prototype with two display pages.
Den grå zonen : En uppsats om hybridregimens karaktärsdrag samt en fallstudie av Ryssland
C-essay in political science by Anna Höjenberg and Maria Stenberg, spring of 2006?The Grey Zone ? An essay on the characteristics of a hybrid regime and a case study of Russia?. Supervisors: Joakim Ekman and Jonas LindeThis essay deals with the concept of hybrid regimes. The purpose is to describe the structure and the content of such a regime-type and try to create a model which can help us to analyse different countries. The essay is divided into two sections.
Den skamlöse Jesus : Tempelrensning, en kamp om heder
This paper aims to explore the possibility of reading the Temple cleansing stories of John and Mark through Bruce J Malina?s honor/shame model, as E. Randolph Richards do. The analysis searches in John?s and Mark?s Temple cleansings for the presence of the notions of honor and shame, as Malina uses those concepts in his model.
Migration och vegetationsupptag av radiocesium i åkermark - en långtidsserie av mätdata samt en långsiktig simuleringsmodell :
Abstract
The accident in 1986 at the nuclear power station in Chernobyl, Ukraine, dispersed radioactive cesium over large areas of Europe. The half life of 137Cs is 30 years and this radionuclide also behaves like potassium, which means that it can easily be taken up by the vegetation or be adsorbed in to the structure of clays, principally illitic clays. When radiocesium decays ionizing radiation is emitted, which is harmful to humans that are exposed, either directly or indirectly through food intake. It is there-fore important to know what happens to the cesium that is dispersed into the environ-ment.
In this project a simulation model was constructed to simulate the adsorption and transport of radiocesium in the soil and plant uptake.
Revisionsutskott i svenska aktiebolag: En statistisk analys
The recent development in several countries? legislation and best practice recommendations in relation to corporate governance in general and audit committees in particular have affected Swedish listed corporations in the form of the Swedish Corporate Governance Code and the coming EU-directive. This paper aims to discover what factors affected Swedish listed companies to form audit committees when this was entirely voluntary. We collected data from the annual reports of 121 Swedish listed companies and formed eleven hypotheses as to what factors we believed affected the voluntary formation of audit committees based on Agency Theory, economies of scale and circumstances specific to the Swedish environment. We then analyzed the data through the use of a multivariate logistic regression model.
