Ett gårdsbesök : ger besöket någon kunskap om mjölkproduktion?
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.
Mekaniserad plantering med Eco-Planter i södra Sverige :
This report is a thesis work for a B.Sc. in Forestry exam at the School for Forest Engineers, SLU. The work was an assignment from Södra Skogsägarna and the aim of the work was to investigate the economical and biological output after mechanical planting with Eco-Planter compared with traditional manual planting.
Eco-Planter is a tool for mechanized planting, fixed at the end of the boom on a conventional harvester.
The study confirms that manual planting is less expensive under normal conditions. However, the differences between mechanized and manual planting are not that big and with technical development and/or increased labor costs together with an improved work organization the system with Eco-Planter could be competitive.
The biological output, e.g. planting result and survival rate, seems to be quite good.
Ha?llbar sockerro?rsodling fo?r etanolframsta?llning i Brasilien : Hur slagkraftig a?r dagens ha?llbarhetscertifiering och kan den fo?ra?ndra mark- och vattenpa?verkan fra?n odlingarna?
Climate changes today are mainly caused by anthropogenic activities and the increased emissions of greenhouse gases to the atmosphere and this has raised questions on how to reduce the usage of fossil fuels. Ethanol is a good alternative to conventional gas and has been used in Brazil since the 1970 ?s. In Sweden several newspapers has written about the poor working conditions on many farms thus making the Swedish company SEKAB design a certification for their ethanol to ensure that it can be considered to be a sustainable alternative.Furthermore WWF has developed a certification tool called Bonsucro in cooperation with Coca Cola, Ferrero group, BP and Shell. This is due to the fact that no global certification tool has been available up until now.
Lok Jumbish : utbildning och utveckling i norra Indien
The purpose of the study has been to recognise good development and the factors behind this development. We have chosen an aid-project co-financed first by the Swedish government and later by the government of Great Britain for our study. One of the conditions for good development, according to our chosen theory Another development, is peoples participation. To study good development and peoples participation we conducted a Minor Field Study (MFS) in Rajasthan in the north-west of India in June-August 2001. We had a hermeneutic approach and consequently accomplished interviews and participant observations in the Lok Jumbish project in Rajasthan.

Analys av argument som uttrycks i samband med ett levande rollspel om embryonala stamceller : En designbaserad studie med analysverktyget TKE av hur argumentens kvalitet utvecklas under en undervisningssekvens
Diskussioner om användandet av embryonala stamceller är exempel på ett område där naturvetenskapliga teorier möter en diskussion i samhällshällsdebatten. Värderingar med t ex etiska utgångspunkter påverkar hur naturvetenskaplig forskning bedrivs och hur resultaten från denna forskning tillämpas. När sådana frågor, samhällsfrågor med naturvetenskapligt innehåll, SNI (socioscientific issues, SSI), tas upp i undervisningen är det angeläget att belysa att det i samhällsdebatten förekommer en diskussion där företrädare för ståndpunkter för fram olika argument i frågan. Ett sätt att möta detta behov är att designa en undervisningssekvens som innehåller en rollspelsdiskussion kring en dagordning. Ytterligare bidrag till utvecklingen av argument kan användandet av skrivramar ge.

Lojalitet på arbetet : Ett perspektiv från arbetare till chef
AbstractThis qualitative study has been made to examine which factors that are required to create a work place that can be associated with loyal co-workers. The study covers half structured interviews with nine people on different levels and with different positions, within a manufacturing company in Värmland. Our ambition with this study is to find out if, and if so, in what way the view on loyalty and which factors that are required to encourage loyalty, differ depending on witch level one belongs to in the organization. Our thesis is that our respondents will have various ways of expressing the term loyalty, and that these various ways are linked to the different levels that each employee is currently stationed at.The result of this study shows that the way people look at loyalty, and what loyalty is really about, does not differ that much among our respondents, regardless of their level. The factors that, according to the respondents, are important if one wants to create a work place that can be associated with loyal co-workers are: to be able to feel trust towards and have faith in those one works with, as well as the company and the way things are being run, to be able to experience the feeling of community, and that one is happy with ones work place, as well as ones co-workers.
Polisens utvärdering av farliga hundar enligt lag (2007:1150) om tillsyn över hundar och katter
Aggression is a normal part of a dog?s behaviour repertoire and has always been an evolutionary relevant behaviour. Even if aggression in some contexts is relevant, it is one of the most common problem behaviour reported by dog owners. It has been discussed if some breeds are more likely to show aggression and therefore should be banned. On the 1st of January 2008 a new act was enforced by the Swedish government giving the police force greater authority in decisions to apprehend and euthanize dogs if they after an appropriate evaluation of the dog?s temperament think it is necessary.
Swedish dairy farmers? interest in using price risk management tools : a study of correlating factors
The dairy market will change importantly in the coming years. The quota system, which has regulated the European dairy production, will disappear in 2015 and the European dairy market will then be importantly affected by the volatility characterizing the dynamic of world prices. Besides this, the global demand of dairy products is expected to increase due to the growing world population. Farmers in countries such as the U.S. and New Zealand, when compared to Swedish farmers, show greater familiarity and experience with risk management tools.
En europeisk identitet : en studie av Manuel Castells kriterier vid skapandet av en europeisk identitet
AbstractA European identityA study of Manuel Castells criteria?s to create a European identityC-Essay in Political Science, by Helena Saagpakk, August 2007Supervisor: Björn ÅkerbergPhilosophers and visionaries dreamt early on the idea about a united Europe. This dream was destroyed by the two world wars during the first half of the 20th century. The first community was established in 1950 after the Second World War. This was the beginning of a peaceful cooperation between the member states, and the community later developed into the European Union.
Hållbar utveckling - paradigmskifte inom snabbmatsbranschen? : En flerfallsstudie av hamburgerrestauranger
Sustainability issues have become increasingly high-profile and important in recent decades. In addition, quality issues have come to play a central role in corporate marketing, strategy and management. The word quality can be defined differently in different contexts. This paper focuses on the concept of quality, based on the Total Quality Management perspective, which in Swedish has come to be known as Offensiv kvalitetsutveckling. Offensiv kvalitetsutveckling has been described as a theoretical framework in which an organization continually strives to meet and preferably exceed customer needs and expectations at the lowest cost through continuous improvement, and in which all members of the organization are committed and focused on the organisation's processes. The purpose of this study was twofold. First, to clarify the applicability of the theoretical model Offensiv kvalitetsutveckling as a theoretical explanatory model. Second, to explore how Max Hamburgerrestauranger AB performs according to the values in Offensiv kvalitetsutveckling. A multiple case study was conducted in order to explore these topics. The results showed that Max Hamburgerrestauranger AB is working in a dedicated and value-driven manner, aligned with the values ??that form the basis for Offensiv kvalitetsutveckling. The results also showed that the model for Offensiv kvalitetsutveckling could serve well as a theoretical explanatory model, but that the model would benefit from being developed, enriched or integrated with other models.
Tankar kring Torsk : Isotopanalyser av torskkotor för att undersöka vikten av torskimport i medeltida Sverige
This essay discusses the import of cod (Gadus morhua) in Sweden during the Middle Ages through isotope analysis of cod vertebrae. The isotope analysis is used to trace the cods origin to either the Baltic Sea or the Atlantic Ocean. The bones were subjected to d13C, d15N and d34S analysis; 64 of the analyzed bones met the quality criteria. The isotop data showed that import of Atlantic cod was significant in medeval Sweden. The analysis suggests that there is no specific time or event that the sites start to import cod but this varies from site to site. .
