Teaching English in Mixed-ability Classrooms. Some teachers' thoughts on responding to the needs of all learners
Vårt syfte var att undersöka några lärares tankar om hur det är att tillmötesgå elevers behov i en context präglad av olika kunskapsnivåer. Vi lyssnade genom semi-structurerade intervjuer på erfarna lärare och analyserade deras olika sätt att närma sig klassrum innehållandes olika kunskapsnivåer. Vi intervjuade tre engelsk lärare från ett högstadium och fyra lärare från en gymnasie skola. Våra iakttagelser visar att varierad undervisning är det bästa sättet att möta alla elevers behov och att det är nödvändigt att ha extra material till både avancerade elever och svagare elever. Våra intervjuer framhävde också vikten av kontinuerlig bedömning och behovet att individualisera så mycket som möjligt .
Säsongsvis avverkning : det operativa traktvalets påverkan på den säsongsmässiga uthålligheten i ett bolagsdistrikts traktbank
Due to soft grounds in combination with seasonal variation in soil humidity, there is a lack of stands that are possible to cut during spring and autumn in some geographical regions. For Holmen Skog this sometimes means that a large proportion of the contracted private forest is cut during the winter when the ground is frozen. One consequence of this is that the proportion of winter stands in the stand bank of own forest increases while spring and autumn stands becomes a scarcity. This in combination with milder winters, especially when there is a long period of reduced bearing capacity in spring or autumn, means that the situation rapidly can become critical.
The overall goal with this study was to generate basic data for decision support in the work to achieve a sustainable distribution between own forest and contracted private forest in the stand bank.
The study took place at Holmen Skog, district of Umeå, during autumn 2007 and was based on interviews and an analysis of harvest planning and delivery data.
The study showed that there is a problem with how the cutting is distributed between own and contracted private forest during the year and that it foremost is the proportion of winter thinning of own forest that has increased in the stand bank.
Nutrient efficiency in Swedish dairy cows fed total mixed rations or partial mixed rations
The relatively poor economy in European dairy farming might be improved from efficient feeding systems and dietary management. Increasing herd sizes and transition to loose housing systems in Sweden, increases the possibilities for other feeding systems than separate feeding that is the traditional feeding system in Sweden. Other possible feeding systems are partial mixed ration (PMR) and total mixed ration (TMR), where the TMR system sometimes is associated with overfeeding and thereby increased environmental impact and high feed cost. Diets providing nutrients above or below animal requirements are considered as unbalanced, which in turn are associated with reductions in health, fertility and milk production. On the other hand, a balanced feed ration improves feed efficiency, nitrogen utilization and profitability.
Höggallring i praktiskt skogsbruk : beskrivning av en gallringsmodell för granskog som tillämpas på Trolleholms Gods
When Norway spruce is planted with large initial spacing and grows on highly productive sites in southern Sweden, a high proportion of the stems gets broad annual rings. The thinning programme carried out at the estate of Trolleholm aims to extract stems with too broad ring width. The 3-4 first thinnings are carried out as thinning from above, where only the thickest trees are removed. The internal distance may not fall below 5-7 meters depending on the number of thinning (short distance in young stands).
The aim of this study was to examine the thinning model that is carried out at the estate of Trolleholm. A volume table is calculated to describe the model, and data is collected on temporary plots.
Det här är Mixed Martial Arts! : En kvantitativ innehållsanalys om hur svensk dagspress framställer MMA
Purpose/aim: This study was performed in order to describe how Mixed Martial Arts (MMA) is reported in Swedish daily newspapers during a five-year period. MMA is a relative new sport in Sweden and it is important that the description by the Swedish daily newspapers is accurate and balanced. Then this sport will have the same opportunities to grow as already well-established sports in Sweden. Material/Method: The material consists of 159 articles from six different daily newspapers gathered from 2006-12-07 to 2011-12-07. Quantitative content analysis is used to investigate how the newspapers describe MMA. The result from this quantitative analysis are then compiled, analysed and discussed by applying theories of agenda setting, framing and moral panic. Main results: The result shows that the Swedish daily newspapers give a relative neutral and balanced picture in their coverage of MMA but they are affected to a certain degree of moral panic.
Stamräkning och identifiering av åtgärdsbehov i röjnings- och gallringbestånd med hjälp av låghöjdsbilder
This report is an assessment of the feasibility of using aerial photographs to estimate number of stems per hectare in young forest stands, used together with upper height to determine the need for pre-commercial thinning or ordinary thinning cutting. Aerial photo-interpretation was conducted in 2007 on assignment of Stora Enso Skog AB. A mean height function based on stand age produced with data from Bergvik Skog AB?s 2006 forest inventory assessment was used as a proxy for upper height and used together with photo-interpreted number of stems per hectare to determine the need for thinning cutting according to Bergvik Skog AB?s definitions. The test area is located north of Falun on Bergvik Skog AB?s land.Flight altitude was approximately 900 m above ground and the aerial photos were taken by L&L Flygbildteknik AB.
Begomovirus prevalence and diversity in the TYLCV resistant tomato cultivar Shanty in Nicaragua
Every year begomovirus infections cause severe constraints to the tomato production in Nicaragua. Extensive yield losses are followed by large economical losses, both for the country and the single farmer. During recent years the use of begomovirus resistant or tolerant tomato cultivars has increased in Nicaragua as an effort to improve yields. Still, begomovirus infection is a large threat to the tomato production. Therefore, ongoing work in Nicaragua is focusing on finding new, better, begomovirus tolerant or resistant tomato cultivars.
Stubbehandling med pergamentsvamp och urea mot sporinfektioner av rotticka i bestånd av hybridlärk
Root rot is a big hurter and a huge economic problem for the Swedish and European forestry. The severest hurter is Heterobasidion annosum (Fr.) Bref and it occurs as two different species in Sweden. Commonly referred to as the P-type (Heterobasidion annosum s.s. (Fr.) Bref.) and the S-type (Heterobasidion parviporum Niemelä & Korhonen). Therefore a lot of research has been carried out in this topic to find a solution and reduce this problem, one alternative that have shown to be profitable is stump treatment in thinnings.
Bioenergi från röjningsgallringar : en jämförande studie av fyra flödeskedjor från avlägg till förbrukare
When the Swedish Forestry Act was changed in 1994, brushing of young stands became non mandatory. Since then the annual need for brushing in the country has increased by about 100 000 hectares per year. In later years the price for biomass energy has increased to the same level as pulp wood. The high price on biomass energy and the large areas of stands in the need of brushing has created a new market with its own technical, economical and environmental conditions. There is a development of various techniques to manage the forestry stands with late brushing.

Veto: En motivanalys av FN:s säkerhetsråds fem permanenta medlemmars agerande i konflikten i Syrien.
Aim: The aim of this study is to analyse the possible motives behind the actions of the five permanent members of the UN Security Council in relation to the conflict in Syria. The background of this aim is the Arab Spring and the protests and violence that have followed the uprising. While, in Libya, the UN Security Council adopted resolutions that allowed sanctions against the Libyan government, no such resolutions have been adopted yet in Syria.Theory: The principal theory of the analysis is Stephen D. Krasner´s theory on sovereignty.Method: I have researched various resolutions and statements done in the Security Council, together with official statements from the actors, through Hadenius´ motive analysis methodology and Gilje & Grimen and Ödmans theories on hermeneutics.Conclusion: The conclusion of the analysis is that there, in the case of Syria and Libya, are two different parties in the Security Council. One that stands for sovereignty and one that stands for intervention.
Plantering av gran (Picea abies) på kalhyggen och självföryngring under högskärmar av björk (Betula pendula och Betula pubescens) : föryngringsresultat 7-10 år efter avverkning
The aims of the silvicultural method natural regeneration of spruce (Picea abies L. Karst) in birch (Betula pendula and pubescens) shelterwoods are to establish a new stand of tree seedl-ings and to protect those from high groundwater levels, frost damages and grass competition during its first life years.
The aim of this work has been to (i) describe how shelterwood and stand characteristics influ-ence the results from using natural regeneration of spruce protected by a shelterwood of birch, and to (ii) compare those regeneration results with planting of spruce after soil scarification in clear-cut areas.
Totally 17 harvesting sites have been inventoried and 15 of those included natural regenera-tion in birch shelterwoods, and two were subjects to soil scarification and planting of spruce. The sites represented 7-10 year old final cuts and are located in the coastal (eastern) region of the province of Norrbotten in Sweden. In all areas shelterwood and stand characteristics, as well as the number of main crop seedlings and the height of the highest main crop spruce seedling, were estimated and registered in all areas.
?Jag hade nog bara varit skuggan av vad jag är idag? - En kvalitativ studie om Mixed Martial Arts betydelse för dess manliga utövare
Mixed Martial Arts (MMA) är en kampsportsgren som blandar tekniker från diverse andrakampsporter och där utövaren växlar mellan brottning, så kallad grappling (brottning medlås), samt stående kamp. Sporten har tidigare mött på hårt motstånd och diskuterats en hel delbland annat i media, men dess popularitet har växt mycket det senaste decenniet. Många somidag väljer att börja träna kampsport väljer just MMA.Syftet med uppsatsen är att undersöka vad MMA fyller för funktion för dess utövare. Fokusligger i att undersöka hur stor påverkan MMA har i utövarens liv och hur man kopplar ihopMMA med sin egen identitet. Detta gör vi genom att med MMA-utövares egna berättelserexemplifiera hur detta kan ta sig till uttryck.Studien genomfördes med en kvalitativ undersökningsmetod och det empiriska materialet harsamlats in genom totalt fyra individuella intervjuer.
Jämförelse mellan sådd och naturlig föryngring av tall i Härjedalen
The purpose of this study was to compare naturally regenerated Scots pine (Pinus sylvestris (L.)) against seeded Scots pine in terms of benefits and differences. An inventory was performed at a number of different sites, 4 ? 6 years after soil scarification and data on the number of new established plants, their height growth as well as ground-line diameter was collected. Information about site conditions such as altitude, quarter exposure and frost risk was also collected. A review of previous studies was conducted in addition to the field study.
Fortsatt gran eller självföryngrad björk efter stormfällning? : en ekonomisk analys
The southern part of Sweden, Skåne, is frequently exposed to storms causing great damage to Norway spruce (Picea abies L. Karst.) stands. A storm during the winter 1999/2000 raised the attention of the problem. A lot of forest owners got large areas of spruce stands wind thrown during this storm. Can naturally regenerated birch (Betula sp.) be an alternative on these wind-exposed sites? This was the main question I was facing when discussilig the problems with Esben Möller Madsen, Söderåsens forest district.
The aim of this master thesis was to present an economic analysis of Norway spruce versus
birch.
