Effekten av uteblivna miljöersättningar för anläggning av våtmarker
Environmental subsidies are used as incitements to farmers for development of sustainable land use. In 2014, applications for funding constructed wetlands were not available. This paper examines the environmental consequences of this lack of funding in one intensively cultivated region Skåne län, southern Sweden.A review of wetland applications between year 2007-2013 show that the average rate of applications has been 31 projects per year with a wetland size of 4,48 ± 1,61ha per project (mean±95% CI). Based on interviews, the result suggests that the lack of funding in one year leads to between 102 and 140 ha of constructed wetlands that is not built. This correspond to a total loss of increased nitrogen retention capacity between 6,0 and 91,7 tons/year and a loss of increased phosphorus retention capacity between 0,17and 2,1 tons/year in the drainage basins of Skåne.Further the interviews show that continuity of environmental regulations and funding is important for the farmers? interest in environmental measures.It is concluded that the total loss of increased retention capacity is small compared to the annual transport of nitrogen and phosphorus in the drainage basins.
Uppfattningar om motivation hos deltagare i SPIRA-projektet på Medlefors folkhögskola
Syftet med studien var att undersöka SPIRA-projektets deltagares uppfattningar om motivation och uppfattningar om projektets eventuella påverkan på motivationen. Samt uppfattningar hos några tidigare deltagare i projektet. SPIRA-projektets syfte är att stärka kompetensen hos sina deltagare och målgruppen är individer som varit arbetslösa i ett år eller mer, alternativt sjukskrivna i minst sex månader. Tidigare forskning inom arbetslöshet och motivation tyder på att de individer som drivs av en motivation med en hög grad autonomi har en större chans att vara lyckosamma. De anses även vara mer ihärdiga i sitt arbetssökande och har ett högre välmående än de som drivs av motivation med en låg grad autonomi.
Ljusets betydelse för rotknoppars groningsvillighet i åkermolke (Sonchus arvensis L.)
This study is about how changed light conditions induce dormancy in plants. It is divided in two parts. First a literature study where quantification of light, the concept dormancy, photoperiod and light quality are discussed. Second an experimental part, where the importance of light for sprouting capacity in root buds of perennial sow thistle (Sonchus arvensis L.) is investigated.In the science in how flowering in plants are induced the concepts short day/long day plants and light dominant/dark dominant are well-established. These concepts can also be applied to how light induce dormancy in plants.
Lönsamhetsbedömning av utökad MR-kapacitet på Karolinska Universitetssjukhuset
This thesis analyses how a radiology department at the largest hospital in Sweden, Karolinska University Hospital, most profitably could expand its capacity for investigating cancer patients using magnetic resonance imaging (MRI). The queues today for patients waiting to be scanned are long, which delays the start of cancer treatments. Meanwhile the hospital has a budget deficit of half a billion SEK, which make any expansion hard. In this thesis we evaluate the alternatives of investing in new machinery; utilize the current machinery better by using them more days annually or through a shift work system. Finally we evaluate a combination of these.
Systemanalys flingtork : Produktionseffektivisering
BillerudKorsnäs is a leading global provider of primary fiber-based packaging materials and on Gruvöns Bruk in Grums, they have chosen to invest millions in the boiler at the facility to increase the total capacity of the factory. This results in the Pulp Flash Dryer at Gruvön being burden more, which makes it important that it is of great reliability and can be run with a high capacity. The reliability of the Pulp Flash Dryer at Gruvön is not as good as one could hope, which leads to reduced availability and production, as well as to increased maintenance costs. There are a number of different reasons for this, but all the casual links are not known.The purpose of this project was to perform a system analysis of the Pulp Flash Dryer to identify bottlenecks and the most critical parts from a capacity- and availability perspective. Appropriate methodology for the system analysis was used and would be used in a structured way to perform the analysis with data from the process and the maintenance system.
Utveckling av kognitiva färdigheter och läsförmåga hos barn med mild och måttlig hörselnedsättning i ett ettårsperspektiv
The capacity to process and to remember information is a basic condition for language ability and for coming reading ability. Reading ability is strongly connected to phonological awareness, receptive vocabulary knowledge and working memory capacity. In what way hearing impairment in children affects development of cognitive skills and later on reading ability is an area that has attracted minor attention for research.The aim with this study was to investigate changes in cognitive skills and reading ability in children with mild or moderate hearing impairment after one year of progress and furthermore if any connections between any increases of the abilities were to be found. Comparisons were made with results from age adequate normal hearing children. Moreover prosodic ability on word-level was tested this year.
Motivation till viktminskning
Eftersom övervikt och fetma är ett stort problem i dagens samhälle är det viktigt att forska i hur en framgångsrik och hållbar viktnedgång frammanas. Denna studie syftar till att utforska människors motivation till viktminskning. Undersökningen har en deduktiv ansats där Self Determination Theory valts som utgångspunkt. Sex personer som aktivt deltar, eller har deltagit, i ett viktminskningsprogram intervjuades i syfte att undersöka motivationsfaktorer till viktminskning samt huruvida de grundläggande psykologiska behoven autonomi, kompetens och social tillhörighet tillfredsställs. Intervjuerna analyserades genom en innehållsanalys där koderna var teoristyrda.
Samspelseffekter vid kapacitetsförbättringar. : Exempel från Dalabanan.
The trend in the transport sector is moving towards eco-friendly, fast and convenient transportation,this results in higher demands on railway transports. To meet the demand and quality requirements,the Swedish railway network will have to expand. The cheapest way is to expand little by little butwhat impact do these small steps actually have on the capacity?This thesis examines the interactions of different improvement for the capacity on a single-trackrailway. Through simulations in the software tool RailSys this report studies what effect block signals,extra meeting stations and rebuilding existing two track passing loops to three track loops have onthe capacity.
Att optimera samhället inför klimatförändringar : Sårbarhet och anpassning på dagordningen
This thesis examines the ways in which adaptation and vulnerability are framed in national and sectorial policy-documents dealing with expected societal impacts of climate change. By using theories of discourse and ideology, the analysis aims to find and understand important ideas and presuppositions that are explicitly or implicitly expressed in these documents in order to make possible and tangible the institutional production of policy within the potentially far-reaching problematique of climate change adaptation and vulnerability. The analysis shows that there are two main perspectives through which vulnerability and adaptation are framed; one focusing limits to societal robustness; and one contesting the institutional capacity to implement adaptations. The author understands these framings as complementarily optimizing preconceived social and economic relations, something that might, in fact, reduce the response capacity of people..
Introjektiv motivation och dess förhållande till arbetsrelaterad stress
Syftet med denna studie var att undersöka introjektiv motivation och arbetsrelaterad stress. Studien grundades i Self-determination theory och delades upp i studie 1 och 2. Syftet med studie 1 var att undersöka huruvida introjektiv motivation kan delas upp i två motivationstyper. Ett mätinstrument utformades för att undersöka sambandet, med data från 77 respondenter. Resultatet visade på ett signifikant, positivt medelstarkt samband.
Utvärdering av utrustning för skörd av äpplen avsedda för färskkonsumtion
During the autumn 2009, a 15 hp degree project was accomplished. The objective of the study was to describe different equipment alternatives, suitable for fresh market apple harvest. A field study was conducted during the harvest period to evaluate the efficiency (kg / person/ hour), using the different equipment. Four different systems are described in the study; Pick-ing-bag, Picking-train, Pluk-O-Trak and the Conveyor Harvester. The information about the systems is based on interviews with growers together with previous studies.
Spetsbärförmåga hos betongpålar slagna i friktionsjord
The purpose of this study was to build a database for point-bearing piles in dense noncohesive soil, predominantly moraine. Further, the database was analysed and areas with difficult geotechnical conditions was identified.The database includes for point-bearing piles driven to refusal in moraine. Piles with mainly shaft friction have been excluded. Only concrete piles have been included. Geographically the database covers almost all geotechnical conditions of Sweden.
Fysisk aktivitet som nytta eller nöje? : En kvantitativ studie av gymnasieelevers motivation för fysisk aktivitet
Föreliggande studie undersökte en eventuell skillnad i fysisk aktivitet mellan inre (intrinsic) och yttre (extrinsic) motiverade gymnasieelever med utgångspunkt från SDT-teorin (Self-Determination Theory) samt även eventuella köns- och åldersskillnader. Enkätformulär med items från IMI- (Intrinsic Motivation Inventory) och EMI- (Extrinsic Motivation Inventory) skalan för motivation tillsammans med det korta IPAQ-formuläret för fysisk aktivitet delades ut till 194 friskole-gymnasieelever från yrkesinriktade program. Resultatet visade att elever som var mer inre motiverade också var mer fysiskt aktiva. Ingen könsskillnad fanns för fysisk aktivitet eller för inre motivation. Inom IMI-subskalan för självständighet hade kvinnorna ett signifikant högre medelvärde än männen.
Skogsåkeriägares inställning till organisationsförändringar :
There are two groups of haulage contractors in roundwood transport , those who are contracted direct by the transport buyer and those who are connected to a freight company which in its turn is contracted by the transport buyer. Today the roundwood haulage is dominated by contractors with one to two lorries. The effort of coordinating transportation for a transport buyer is dependent on how many communication contacts that must be managed (how many individual haulage contractors the transport buyer has to work with). A structural change in the sector that leads to a decrease in the number of haulage contractors but an increase in the capacity of each contractor, makes it possible for a transport buyer to coordinate transports with fewer communication contacts. The reason why a company reaches a certain size can be explained by the number of contracts it makes and manages.
Rätt gåva för rätt tillfälle
This master thesis is a study of the Swedish hydropower capacity to balance wind power. The Swedish government has decided that it should be possible to produce 30 TWh from wind power in the year 2020. The Swedish municipalities have to have plans for wind power plants with total yearly generation of 30 TWh. Wind power is an variable energy source that needs to be balanced by other energy sources. In Sweden the Swedish hydropower can be used for balancing a large scale introduction of wind power.
