Tid i all oändlighet och förgänglighet. En studie av tidsanvändningen i Sverige sedan 1980-talet

This master thesis in economics discusses the time use of today as well as the observed trends in time use over the last 20 years in Sweden. This is done by analysing time-use and consumption data at the microeconomic level, i.e. by explaining individual behaviour given the economic assumption of a rational behaviour. We reach the conclusion that the value of time is an important explanatory variable concerning the rationality in that time is used differently by different individuals and in the changed use of time. Furthermore, other variables such as social norms and the process benefit of a certain activity, i.e.

Skogsbrukets framtida arbetskraftsförsörjning : skogsmaskinföraryrkets attraktionskraft

The scarcity of qualified forest machine operators as well as the increased competition for competent machine operators among others from the mining industry in Norrland, were the reasons to investigate what attracts and what deters active and potential forest machine operators to the occupation. An interview study was conducted among four groups with four persons in each group. The groups were students in year 1 and 3 respectively at a forestry school at upper secondary school level as well as employees of a forest company and employees of contractors. The majority of all respondents were of the opinion that their interests in machines had been important for the choice of occupation. But for the active machine operators both the interest in the forest and their interest for machines have had importance for choosing this occupation.

EFFEKTIVARE UTLASTNING FÖR LAGER UNDER HÖGSÄSONG PÅ HUSQVARNA AB

Husqvarna AB operates two warehouses located in the area of Jönköping. The most important task is to manage the large volume fluctuations during the peak season. DHL Exel Supply Chain (DESC) run the warehouses and the domestic transportations is outsourced to DHL Express. A number of forwarder agents are responsible for distributing the export gods. In the present situation a bottleneck occurs at the warehouse loading section, and the consequence is fulfill the time of delivery for all customer orders.

Klassning av fjällbjörkskog enligt FAO:s definition av skogsmark med hjälp av flygburen laserskanning

Sweden?s forestry legislation was updated in 2010 and a new definition of forest land was introduced. This definition was adapted to the one used by the Food and Agriculture Organization of the United Nations (FAO) for international statistics on the state of the world's forests. It is in short based on the lands ability to grow forest that reaches 5 meters, 10 % canopy closure and has a continuous distribution, according to FAO at least 0.5 hectares. A country-wide laser scanning is now carried out for the production of a new national elevation model; the laser data also provides information on forest height and density.

Logistiskt förändringsarbete

Idén till uppsatsen uppstod efter att ha läst Jan Carlsson et al: s avhandling och artiklar inom ämnet logistiskt förändringsarbete. Flera forskare problematiserar avsaknaden av teorier inom ämnesområdet samt lyfter fram bristerna i den existerande logistikforskningen som enligt forskarna inte lyckas fånga logistikförändringarnas komplexa natur.Syftet med uppsatsen var att med utgångspunkt från befintlig forskning inom området för logistiskt förändringsarbete och supply chain management, utvärdera och analysera logistiskt förändringsarbete i två företag. Utifrån befintliga teorier sammanställde vi en övergripande syntes med syfte att visa vår tolkning av hur logistiskt förändringsarbete skulle kunna hanteras. Ur denna syntes extraherade vi variabler som ansågs vara av betydelse för den empiriska studien. Undersökningen genomfördes som en fallstudie i två företag med ostrukturerade intervjuer med personer inblandade i förändringsarbetet.Resultaten vi kom fram till var att medvetenheten finns om att ta hänsyn till flera dimensioner i förändringsarbetet men det förarbete företagens utför underbygger inte alltid denna vetskap..

Liv i d?d ved: En unders?kning av f?rh?llningss?tt till d?d ved p? ?ppeltr?d i tr?dg?rdshandb?cker och bland yrkesverksamma tr?dbesk?rare

In this essay, several factors in apple tree care (specifically in relation to whether dead wood should be kept or removed) are highlighted for example, aesthetics and biodiversity. To present some background, the essay begins by introducing some previous literature on dead wood. This leads into how dead wood is treated within forestry. Next, previous research on dead wood in fruit trees is mentioned. Cultural and historical management methods are also highlighted.

Påverkan på Valboåsen från verksamheter inom Svedens industriområde samt närliggande områden : hot mot grundvattnets kvalitet och kvantitet?

The aim of this work was to find out what potential contaminants from roads, residential area and businesses within Svedens industrial area that can affect groundwater quality and quantity. Data collection was from SGU, VISS, internal material from Gävleborg county Administrative Board and Gävle municipality archive. GIS software ArcGIS was used to create the map images in the work. The studied area is located approximately ten kilometers west of Gävle city and consists of the esker Valboåsen, which is a glacifluvial deposit that in its central parts consist of coarse material that is overlaid by sand, clay and silt. North of esker Valboåsen there are the river Gavleån which has an inflow to the groundwater in the esker. This inflow represents the largest part of the groundwater recharge.

Do retention trees affect the composition of ectomycorrhizal fungi? : a comparison between clear-cuts areas with and without retention trees in pine forests

Under det senaste årshundradet har de svenska skogarna genomgått en omfattande förvandling, från mer eller mindre naturligt dynamiska till hårt brukade skogar bestående av monokulturer av tall eller gran. Denna förändring har lett till en minskning av den biologiska mångfalden, att många arter som är beroende av skog har minskat radikalt och hotas av utrotning. Som ett försök att främja variation, biologisk mångfald i allmänhet och förhindra minskningen av rödlistade skogsarter introducerades i början av 90-talet en viss naturvårdshänsyn i brukade skogar. I den här studien utvärderas den påverkan som kalavverkning har och den betydelse hänsynsträd har på artsammansättningen och förekomsten av ektomykorrhizasvampar (EMF) under de första 20 åren efter kalavverkning. Studien utfördes genom extrahering och identifiering av svamp-DNA från jordprover tagna på kalavverkade ytor, nära hänsynsträd och i gammal skog i ett begränsat geografiskt område i norra Sverige.

Effekten av suggans näringsstatus på fostertillväxt och smågrisöverlevnad

The pig industry suffers economical loss due to stillbirths, piglet mortality and low birth weight. This is due to breeding programs that have resulted in larger litters. It has been suggested that these problems are due to the metabolic state of the sow during gestation and the fact that she might not be able to supply her foetuses with enough nutrients for survival and a high and even birth weight. A lot of research has been done to investigate whether body weight and back fat thickness of the sow has any impact on her reproductive traits and if there are any special feed components that improve reproduction. Fibers and unsaturated fatty acids have a positive impact on reproductive traits as long as the sow is fed a sufficient amount of energy and protein during gestation and lactation.

Mjölkraskvigors tillväxt på naturbete :

To turn the dairy heifers out on pasture is the most natural way for the cattle to get feed. At the same time it is cheap and if it is right treated a feed of high nutritive value. The problem today is to get dairy heifers to grow enough when they are grazing at natural pasture for the entire summer. Therefore, the opinions differ whether pasture is a resource or a problem. The increasing interest of pasture production is due to the fact that you can receive grants for preserving valuable natural assets and cultural landscape elements in the pasture land. A high grazing pressure is necessary to preserve an open landscape and a great variety of species. In the same time the heifers have to supply their nutritive needs in order to grow and be large enough to show heat and be pregnant in right time to calve with a sufficient body size and at an economically right age. This paper includes a literature review on natural pasture, pasture production, and growth of dairy heifers together with own interviews with dairy farmers about their point of view to the pasture husbandry on the farms, how they plan for pasture, look after natural pasture, treatment areas and take care of the calves and heifers. The results indicate that the time it takes and the demanded work are the biggest factors to how and why the farmers do as they do..

Brandrelaterade insekters lokala artrikedom i förhållande till olika miljövariabler : Fokus på betydelsen av konnektivitet på brandfält i boreal skog i Västerbottens län

The last century, forest fires have decreased in frequency due to efficient fire-suppression along with the growth of the industrial forestry. Since 1990, fire has been reintroduced under controlled forms to recreate burnt habitats. Many species that are dependent on, or benefits from, forest fires have increased since fire was reintroduced. The importance of connectivity is often addressed in ecological research. This is particularly important for species dependent on short-lived habitats such as burnt forests.

Lönsamhetskalkyl för produktion av gran på markavvattnad och askgödslad myrmark

In Sweden there are about 4 million hectares of bare peat (mire). This land has great potential to be transformed into productive forest land, provided drainage is carried out and, in some cases, even fertilization with ashes. Drainage of mires is necessary because the high groundwater table prevents trees from growing due to reduced oxygen availability. Some of the key nutrients that trees need to grow appear in too small quantities in mires, especially potassium (K) and phosphorus (P). Ash from the combustion of biomass contains these elements and is therefore suitable as a fertilizer.

Alla vägar leder till fantasy: en studie av hur fantasyläsande BHS-studenter går tillväga för att få tag på skönlitteratur

Fantasy literature has a rather strong position in countries with an English-speaking population but not in Sweden. The supply of fantasy in Sweden is much smaller than that in for example United Kingdom. Does this affect the Swedish readers of this genre? If it does, how does it affect them? The aim of this thesis is to find out how a few fantasy-reading students at the Swedish School of Library and Information Science get hold of the fiction they want to read and who and/or what influence their decision of which book to read. In order to avoid confusion we are also going to try to find out how they define fantasy since it varies from person to person what is included in the genre.

Inköp i läkemedelsbranschen- Jämförelse med Best Practice modell - Novo Nordisk Danmark

Läkemedelsbranschen är idag hårt konkurrensutsatt vilket skapar incitament till förändring av de interna processerna av vilka inköp utgör en. Läkemedelsbranschen har av tradition ansetts ha en eftersatt inköpsverksamhet för att vara en så mogen bransch. Vår undersökning gick ut på att jämföra en Best Practice modell för inköp med inköpsverksamheten i läkemedelsbranschen. För läkemedelsbranschen finns helt klart utvecklingsområden och utmaningar i förhållande till den gängse inköpsteorin och Best Practice modellerna. Vid en jämförelse med Best Practice modell för inköp och vårt fall identifierade vi ett antal avvikelser beroende på rationella, politiska och ekonomiska orsaker.

Guld i Sverige - Från urtid till nutid

The Earth and everything else in the universe was created in the Big Bang around 14 billion years ago. A point with tremendous density and mass began to expand and more and more atoms began to form. From the first and lightest like hydrogen and helium to heavier atoms such as iron and eventually gold. The formation of the Earth occurred about 4.6 billion years ago and so the first gold atoms were concentrated only here. It is however believed that much later in Earth's history an extra supply of gold occurred thanks to massive meteorite bombardments.
