Neonicotinoids and honeybee health : the effect of the neonicotinoid clothianidin, applied as a seed dressing in Brassica napus, on pathogen and parasite prevalence and quantities in free-foraging adult honeybees (Apis mellifera)

Sub-lethal doses of neonicotinoids have been shown to negatively impact the health of honeybees. However, most studies to date have exposed bees only artificially to these pesticides under laboratory conditions. There have been just a few well designed and replicated studies of the impacts of realistic neonicotinoid exposure on honeybees foraging under field conditions. In order to close this knowledge gap, and to test the influence of the neonicotinoid clothianidin on honeybees, we used a study system of 16 paired, spatially separated (>4 km) spring oilseed rape fields in the south of Sweden. The fields were paired according to land use, the surrounding landscape and geographical proximity, using GIS.

?Sumpighet och Vattensjuka? en centralmakts påverkan på ettlokalt landskap

The purpose of this study was to examine the goals, possibilities and rationales that could be found in the discussions concerning the digging of ditches by governmental subsidiaries in order to drain the peat bogs of late nineteenth century Sweden. A further aim was to look at the effect on the landscape on a local level i.e. Släthults moss in Bäckaby parish, Småland in the south eastern part of Sweden. In order to be able to explain the connections between politics and landscape changes in a local population and its deciding bodies, influenced by ideas, science and production, a quadruple helix model developed from a triple helix model by Björn-Ola Linér was used. As a model of environmental history, three step thought was used, borrowed from Donald Worster.

Vilka faktorer påverkar ett mjölkföretags tillväxt? : en jämförelse mellan Sverige och Danmark

Dairy farms have during a long time been under pressure and this situation was aggravated during the spring and summer of 2009, when profitability declined to historically low levels. Lower milk price and relatively high input prices have caused Swedish dairy farms great liquidity concerns and profitability problems. For a long time, Denmark has been identified as a leading country for the agrarian development with a leading structural rationalization and willingness to grow. In 2009, it was shown that the Danish agriculture, which is generally more leveraged, has difficulties in maintaining profitability and when market price of land started to fall, the proportion of technically insolvent agricultural enterprises rose dramatically. In light of this prevailing situation, this study highlights differences between Denmark and Sweden with the hope to learn from each other.

Barn och ungdomars hälsa - En enkätstudie om hur elever upplever sin skolmiljö i relation till sin psykosociala hälsa

Den psykosociala hälsan bland Sveriges befolkning blir allt sämre. Undersökningar visar att mellan femton och fyrtio procent av befolkningen lider av oro, nedstämdhet, sömnbesvär och trötthet. Den största ökningen har skett i yngre åldrar med i stort sett fördubblade andelar. Då skolan utgör en central plats i barns och ungdomars liv är det viktigt att den är välfungerande och arbetar för att främja elevernas hälsa. Syftet med studien var undersöka hur eleverna på en skola i Helsingborgs stad upplevde sin skolmiljö i relation till sin psykosociala hälsa samt om skolans hälsofrämjande arbete påverkade elevernas upplevelse av hälsa i positiv riktning.Datainsamling har skett genom enkäter till alla elever i årskurs 4 ? 9.

Så nära mig men ändå på distans En presentation av EFT, Emotionally Focused Couple Therapy och en studie av ett försök att arbeta med delar av EFT i en svensk familjerådgivning

In my work as family counselor I have long seen a pattern with many of the couples I?ve met. Thepattern consists of a movement where one person take an offensive, accusing and sometimeschasing position, whilst the other person is on the retreat. Over and over again I?ve made theexperience that if you help them solve a single problem another one pops up.

Omval på gymnasiet

Genom praktiska och teoretiska studier på studie- och yrkesvägledarprogrammet har vi kunnat se en ökning av de elever som gör ett omval efter ett år på gymnasiet. Syftet med undersökningen var att se bidragande orsaker till att ett eventuellt omval sker. En kvalitativ studie har gjorts genom intervjuer med fem elever som gått ett år på sitt omvalda gymnasieprogram. Detta resultat har ställts i relation till Linda. S Gottfredsons teori kring begreppen begränsningar och kompromisser i studievalet samt SCCT-teorin där fokus ligger på självskattning.

Uthållig estetik i landskapet - om att synliggöra sitt förhållningssätt till hållbarhet : Sustainable landscape aesthetics - to demonstrate ones attitude towards sustainability

Abstract In my work, I have tried to define and clarify the conception of sustainability seen from my perspective as a landscape architect. With a basis in literature studies, I have analysed and commented on different applications, contents and meanings of sustainability and endurance. This compilation is based on how a number of writers, researchers and authorities consider the importance of integrating ecological, social and economic aspects of sustainability in city planning. My perspective has mainly been founded on the anthologies and compilations from the 80´s and 90´s where Per G. Berg and Björn Malbert acted as editors.

BARA MATEMATIK? : En empirisk studie om matematiksvårigheter och dess orsaker

SvenskaDetta är en kvalitativ studie som är baserad på semistrukturerade intervjuer. Syftet med detta arbete är att ta reda på hur två matematiklärare och en specialpedagog ser på/beskriver matematik­svårigheter och hur de arbetar med elevernas matematiksvårigheter som de upp­täcker hos sina elever. Jag är väldigt intresserad av att höra vilka matematik­svårigheter och orsaker till matematiksvårigheter lärarna ser hos sina elever samt lära mig hur skolan och lärarna jobbar med dessa svårigheter hos eleverna. Samtliga informanter hade samma svar på mina forskningsfrågor. I resultaten av hela min studie har jag kommit fram till att orsaker till elevernas matematiksvårigheter bland annat är: dåliga baskunskaper, låga baskunskaper förståelse av positionssystem samt begrepp.

Framtiden för snabbladdning och marknadsaktörerna inom eMobilitys syn på laddinfrastruktur

The electric vehicle market has potential to contribute to Sweden?s national goal to have a fossil fuel independent transport sector by 2030. However, the market answers to a lot of challenges making it difficult for the market to fully reach its potential. The volume of electric vehicles has seen a steady increase during the last year (2012), although many of these vehicles are mostly for PR purposes or bought by the public sector that wants to lead by example. Still, barriers in the form of high purchase costs, an anxiety for the limited battery capacity and the lack of standardisation are some of the problems that the market is struggling to solve.

Survey of regulations concerning pesticides in Sweden and the EU : cultivation techniques and competition aspects for Swedish onion and apple producer

As a member of the EU, Sweden has, in some cases, transferred the controlling rights to the Union. This means that the rules defined by the EU must be followed in all member countries, including Sweden. The European Agricultural policy constitutes the largest part of the EU's annual budget and is in contrast to many other areas fully funded at EU level. The last decade, many new regulations on chemicals and pesticides have been introduced which brought great changes and a lot of work throughout the Union, including Sweden. Sweden has always had a strict policy on chemicals and has been at the forefront when it comes to sustainable agriculture and environmental management.

Konkurrenssituationen fo?r den svenska morotsbranschen :

The Swedish carrot market is dominated by a few big companies and three of them stands for 50 % of the market. During the last twenty years the number of growers has decreased, the area and the harvest have increased. The big producers have invested in advanced and expensive postharvest equipment that fulfils the high standards of the food industry. Few carrot producers are members of an organisation and they keep contacts with there buyers one by one. The buyers are mostly wholesalers and these have during a long period of time decreased the number of suppliers.
