Structural rationalizations and regionalization of the agricultural sector in Sweden has lead to unevenness in thedistribution of plant nutrients. Nutrients are lost from crop producing farms as harvest products are sold, whilefarms with animal production often have manure in excess of their needs. In addition to this the retention ofwater and nutrients in naturally occurring wetlands has decreased due to a reduction of wetlands in number andsize in the agricultural landscape. This increases nutrient levels in agricultural run-off and causes eutrophicationas well as nutrient losses from arable soils. One potential solution to both problems would be to store nutrientrichsurface water from agricultural areas and use it for irrigation of agricultural crops.

En homogen grupp är inte svaret på en lyckad klass : Pedagogers attityder till inkludering av särskolans elever i ordinare grundskola.

Metodik för bestämning av åkerdikens status : fallstudie av ett dike i Munktorps socken

Agricultural drainage ditches are links between fields, lakes and oceans, having the potential to transport e.g. sediment and nutrients. When in a good condition, drainage ditches can act as sinks for e.g. phosphorus and sediments and prevent eutrophication downstream. The aim of this study was to determine the condition of one agricultural drainage ditch and to come up with suggestions for appropriate measures. The aim was also to determine which of the ditch?s properties that were possible to evaluate visually, which processes they represented as well as which properties required complementary physical analysis. This in order to contribute to the work of developing a method for determining the status/condition of agricultural drainage ditches.

Taylor i kebabfabriken

Efter millenniumskiftet uppfattas det som närmast ?rätt? att moderna framtidsinriktade verksamheter, stora som små, bör arbeta med kvalitetsstyrning[1].  Åtgärder inom kvalitetsstyrning innebär att moderera och justera tillverkningsprocessen så att de producerade enheterna håller sig till en standard[2]. Företag ställs ständigt inför flera olika alternativ om hur de kan förändra sitt arbetssätt, och öppna sig för att ta till sig olika kvalitetshöjande koncept. Dessa ska leda till att organisationen och dess processer blir mer effektiva och produktiva, för att i sin tur sänka kostnader, maximera vinsten, bemöta kundernas efterfråga, och kunna leverera billigare produkter av högre kvalitet på ett snabbare och enklare sätt.

Rimligt tvivel? : En studie om historievetenskaplig stringens i en juridisk kontext

What happens when historical theories are used as evidence in a trial? Is it possible for historians to use their own scientific tools when acting as participants in a juridical process? And how do judges deal with historical evidence? The aim of this study is to answer these questions by analyzing a specific trial, known as ?Härjedalsmålet?. Härjedalsmålet was a court case about the Sami people?s right to let their reindeer graze on private property grounds in Härjedalen during the winter season. Their claim to this right was based on prescription of time immemorial.

Hästens, Equus caballus, termiska komfort - hur kan djurskyddskontrollanter bedöma hästens välfärd?

This review paper summaries scientific research about horse thermoregulation and the consequences of using a blanket. Horse owners put blankets on their horses to protect them when they are clipped, to protect them from bugs, to keep them clean and so on. This can have consequences for the horse which their owners might be unaware of. I have tried to answer following questions by searching the available scientific literature; ? How can the horse maintain thermoregulation? ? Is there a risk of suffering when horses wear a blanket? ? Is there a risk of suffering when horses do not wear a blanket? ? How can animal inspectors estimate the welfare of horses when they wear or do not wear a blanket? My result shows that horses who wear a blanket have an increased risk of becoming overheated, develop a chafing, have an increased exposure hazard and have a restrained natural behaviour.

Historiografi och paradigm i forskningen om kalla kriget : En komparativ analys av diplomatihistoria och internationella relationer

Adopting a socio-cultural approach to the study of cold war historiography, this master?s degree essay is a comparative study of the two main disciplinary fields of cold war scholarship, diplomatic history and international relations theory (IR). The study applies the theory of scientific development formulated by Thomas Kuhn and the concept of paradigm on the field of cold war research.Diplomatic history and IR shows many similarities in their development, and in the importance different schools has had in scholarly debate. These different schools are analysed as paradigms, a concept that has been more willingly adopted within IR than in diplomatic history. The transition from what historian John Lewis Gaddis has termed Old Cold War History to New Cold War History is discussed in terms of paradigms and paradigm shift.

Kunskapen, professionen och makten ? En kvalitativ studie om socionomens villkor och förutsättningar

My main purpose with this study is to investigate how the social worker relates to knowledge, power and profession. From this purpose has also the concept ?to be a social worker? emerged.The study is based on a qualitative study and consists of semi-structured interviews with seven social workers from different fields of expertise.The result of the study shows that the knowledge is dependent of different fields of expertise. But in the contact with the client, regardless of field of expertise, the knowledge is gathered through a reflective pattern. Through theoretical attempts and earlier experience from social workers, this is brought to life in this unique meeting.

Vägen till jämställdhet - Kvinnor i styrelserum eller män i förskolan? : En kritisk analys av den svenska jämställdhetsdiskursen

Equality between the sexes has been discussed in Sweden for more than 50 years. In the 60´s and during the 70´s the discourse that dominated the debate was based on the assumption that both men and women needed to liberate themselves from their traditional gender roles. In this approach information and education was perceived as the key to equality. During the 80´s however, power and subordination became the main focal point of concern within this debate, and focus upon changing the patriarchal power structures dominating society were perceived as the principal key for establishing equality between the sexes. Today, the latter discourse still dominates both the scientific and the political perspective upon equality.

Sexualitet bland äldre - En litteraturstudie som belyser äldres behov av sexualitet

The aim of this literature review was to put together scientific knowledge about the need of sexuality among elderly people, so that the nurse in the future can use this knowledge in nursing. The research questions that will be answered are: In what extent do elderly people have the need to experience sexuality? In what extent do elderly people have the possibility to practice their sexuality? In what degree do the nursing staff respect and understand elderly people's need of sexuality? How can nursing staff support elderly people in their sexuality? The method used to answer the research questions was analysis and interpretation of ten scientific articles. The results, which are presented within ten categories, shows that elderly people have a need of sexuality. Loneliness, lack of privacy and knowledge and attitudes are factors that affect elderly people's possibility to express their sexuality.

PRESTIGE, KARRIÄR OCH OPEN ACCESS Forskares syn på publicering i vetenskapliga tidskrifter

Dissatisfaction with the current market for scientific publishing, dominated by a few large publishers able to obtain high subscription fees, gave birth to the Open Access movement. One problem for the Open Access movement, which aims at making research results freely available, is that scientists are reluctant to publish in journals that are free on the Internet, so called Open Access journals. This master's thesis aims at showing how scientists reason about their own publishing in scientific journals. It is investigated which factors are important when scientist decide on which journals to send their articles. The aim is to increase the understanding of scientists' views on Open Access.Six interviews were conducted with scientists in Biomedicine at Lund University.

The river Selångersån runs through thenorthern Swedish city of Sundsvall, splittingthe city in two as it winds through thevalley between Södra- and Norra Stadsbergetand out into the Baltic Sea.The river is a national interest of nature conservationbut at the same time in the middleof an urban development string for the city,creating a complex situation of developmentcontra conservation of natural environment.This project attempts to create a strategy oflandscape urbanism for the area surroundingSelånger Bay, four kilometers upstreamalong Selångersån. A sensitive wetland, todayrather forgotten but with great potentialfor introducing wild nature as an active partof the city. Or rather, initiating a processwhere the built environment can infiltrateand enrich the natural environment gradually.A city park in this location to initiate thisprocess could be a joint project of the city?sresidents with the scope to become a projectin constant development.The idea of the project is to offer a large ecologicalpark and meeting place near the citycenter. This will be achieved by clarifyingthe activities and values that already existin the park, such as the largest living deltai the region, football fields and a medievalchurch ruin, and by creating new paths.
